  1. A preliminary report on the initiation of a clinical research program in an orthopaedic surgery department: roadmaps and tool kits. (United States)

    Merwin, Sara L; Fornari, Alice; Lane, Lewis B


    A formal research program enhances resident training experience, productivity and hones critical appraisal skills. This initiative sought to investigate if an academic orthopaedic surgery department could implement a clinical research program, with the goal of increasing resident scholarly activity, a requirement of the Resident Review Committee, and achieve a parallel aim of enhancing the research focus of faculty. A multifaceted intervention including a needs assessment, appropriation of dedicated research staffing, development of tracking tools and policies, and a formalized research curriculum, followed by additional research time for residents was planned and implemented. The impact of all of these efforts is measured with specific outcomes, pre and post implementation. The North Shore-LIJ Orthopaedic Surgery Department is a high volume clinical and education program with 17 fulltime core faculty and 18 residents at 2 tertiary hospitals. Residents were the focus of the intervention. The participation of faculty as principal investigators and sponsors was a key component to ensure success. The following outcomes were observed post intervention: increases in institutionally-required research training for faculty/residents, number of IRB protocols submitted, abstracts submitted to national meetings, percentage of time faculty report they spend on research activities, additional hours allocated to the new Department sponsored research curriculum and an additional research rotation for trainees. The official inception of a formalized program (2012) with a structured research process, invigorated faculty and trainees to formulate clinical research inquiries, generate hypotheses, create protocols and design and implement protocols. Structured tools, an experienced clinical research "champion" and commitment from departmental leadership were demonstrated as effective in transforming the focus of a clinical department into one with a nascent clinical research program

  2. Conversions from anatomic shoulder replacements to reverse total shoulder arthroplasty: do the indications for initial surgery influence the clinical outcome after revision surgery? (United States)

    Holschen, Malte; Franetzki, Bastian; Witt, Kai-Axel; Liem, Dennis; Steinbeck, Jörn


    The most frequent indications for anatomic shoulder replacement are glenohumeral osteoarthritis and fractures of the humeral head. If anatomic shoulder prostheses fail, reverse total shoulder arthroplasty is often the only remaining treatment option. This study evaluates the influence of indications for primary shoulder arthroplasty on the clinical outcome after conversion to reverse total shoulder arthroplasty. From 2010 to 2012, 44 failed shoulder arthroplasties were converted to reverse total shoulder arthroplasty. Forty-four patients were available for follow-up after a mean of 24 months (14-36 months). Twenty-three of them had received an initial shoulder replacement because of osteoarthritis, while the remaining 21 patients had been treated for a fracture of the humeral head. At follow-up, patients were assessed with X-rays, constant-, and ASES scores. The total number of observed complications was higher in patients revised because of failed fracture arthroplasty (24 vs. 9%). Patients initially treated for osteoarthritis achieved a higher ASES score (71 vs. 59 points; p = 0.048). The normalized constant score was not different between the two observed groups (osteoarthritis 73% vs. fracture 67%: p = 0.45). Complications occurred more often in patients who had initially suffered from a fracture of the humeral head (fracture 23.8% vs. osteoarthritis 8.7%). Scapular notching was more frequent after initial fracture arthroplasty (33 vs. 14%). Indications for initial shoulder replacement have an influence on the clinical outcome after conversion to reverse total shoulder arthroplasty. Patients initially treated for a fracture of the humeral head have a lower subjective outcome and a higher complication rate in comparison with patients initially treated for osteoarthritis.

    Full Text Available Abstract Background The optimal initial local treatment for patients with Graves’ ophthalmopathy (GO is not fully characterized. The purpose of this retrospective study is to describe the clinical outcomes of RT as initial local therapy for GO and define predictors of the need for post-RT salvage bony decompressive surgery. Methods 91 patients with active GO and without prior surgery were treated with RT as initial local therapy between 01/1999 and 12/2010, with a median follow-up period of 18.3 months (range 3.7 - 142 months. RT dose was 24 Gy in 12 fractions. 44 patients (48.4% had prior use of steroids, with 31 (34.1% being on steroids at the initiation of RT. The most common presenting symptoms were diplopia (79%, proptosis (71% and soft tissue signs (62%. Results 84 patients (92.3% experienced stabilization or improvement of GO symptoms. 58 patients (64% experienced improvement in their symptoms. 19 patients (20.9% underwent salvage post-RT bony decompressive surgery. Smoking status and total symptom score at 4 months were independent predictors of post-RT bony decompression with odds ratios of 3.23 (95% CI 1.03 – 10.2 and 1.59 (95% CI 1.06 – 2.4, respectively. Persistent objective vision loss at 4 months post-RT was the most important symptom type in predicting salvage decompression. Chronic dry eye occurred in 9 patients (9.9% and cataracts developed in 4 patients (4.4%. Conclusions RT is effective and well tolerated as initial local therapy for active GO, with only 21% of patients requiring decompressive surgery post RT. Most patients experience stabilization or improvement of GO symptoms, but moderate to significant response occurs in the minority of patients. Smoking status and total symptom severity at 4 months, primarily persistent objective vision loss, are the primary determinants of the need for post-RT salvage bony decompression. Patients who smoke or present with predominantly vision loss symptoms should be

    Full Text Available Abstract Background The consequence of the low rate of penetrating injuries in Europe and the increase in non-operative management of blunt trauma is a decrease in surgeons' confidence in managing traumatic injuries has led to the need for new didactic tools. The aim of this retrospective study was to present the Corso di Chirurgia del Politrauma (Trauma Surgery Course, developed as a model for teaching operative trauma techniques, and assess its efficacy. Method the two-day course consisted of theoretical lectures and practical experience on large-sized swine. Data of the first 126 participants were collected and analyzed. Results All of the 126 general surgeons who had participated in the course judged it to be an efficient model to improve knowledge about the surgical treatment of trauma. Conclusion A two-day course, focusing on trauma surgery, with lectures and life-like operation situations, represents a model for simulated training and can be useful to improve surgeons' confidence in managing trauma patients. Cooperation between organizers of similar initiatives would be beneficial and could lead to standardizing and improving such courses.

  5. [Initial experience in robot-assisted colorectal surgery in Mexico]. (United States)

    Villanueva-Sáenz, Eduardo; Ramírez-Ramírez, Moisés Marino; Zubieta-O'Farrill, Gregorio; García-Hernández, Luis

    Colorectal surgery has advanced notably since the introduction of the mechanical suture and the minimally invasive approach. Robotic surgery began in order to satisfy the needs of the patient-doctor relationship, and migrated to the area of colorectal surgery. An initial report is presented on the experience of managing colorectal disease using robot-assisted surgery, as well as an analysis of the current role of this platform. A retrospective study was conducted in order to review five patients with colorectal disease operated using a robot-assisted technique over one year in the initial phase of the learning curve. Gender, age, diagnosis and surgical indication, surgery performed, surgical time, conversion, bleeding, post-operative complications, and hospital stay, were analysed and described. A literature review was performed on the role of robotic assisted surgery in colorectal disease and cancer. The study included 5 patients, 3 men and 2 women, with a mean age of 62.2 years. Two of them were low anterior resections with colorectal primary anastomoses, one of them extended with a loop protection ileostomy, a Frykman-Goldberg procedure, and two left hemicolectomies with primary anastomoses. The mean operating time was 6hours and robot-assisted 4hours 20minutes. There were no conversions and the mean hospital stay was 5 days. This technology is currently being used worldwide in different surgical centres because of its advantages that have been clinically demonstrated by various studies. We report the first colorectal surgical cases in Mexico, with promising results. There is enough evidence to support and recommend the use of this technology as a viable and safe option.

  9. Femtosecond lasers in ophthalmology: clinical applications in anterior segment surgery (United States)

    Juhasz, Tibor; Nagy, Zoltan; Sarayba, Melvin; Kurtz, Ronald M.


    The human eye is a favored target for laser surgery due to its accessibility via the optically transparent ocular tissue. Femtosecond lasers with confined tissue effects and minimized collateral tissue damage are primary candidates for high precision intraocular surgery. The advent of compact diode-pumped femtosecond lasers, coupled with computer controlled beam delivery devices, enabled the development of high precision femtosecond laser for ophthalmic surgery. In this article, anterior segment femtosecond laser applications currently in clinical practice and investigation are reviewed. Corneal procedures evolved first and remain dominant due to easy targeting referenced from a contact surface, such as applanation lenses placed on the eye. Adding a high precision imaging technique, such as optical coherence tomography (OCT), can enable accurate targeting of tissue beyond the cornea, such as the crystalline lens. Initial clinical results of femtosecond laser cataract surgery are discussed in detail in the latter portion part of the article.

  11. Clinical trial networks in orthopaedic surgery. (United States)

    Rangan, A; Jefferson, L; Baker, P; Cook, L


    The aim of this study was to review the role of clinical trial networks in orthopaedic surgery. A total of two electronic databases (MEDLINE and EMBASE) were searched from inception to September 2013 with no language restrictions. Articles related to randomised controlled trials (RCTs), research networks and orthopaedic research, were identified and reviewed. The usefulness of trainee-led research collaborations is reported and our knowledge of current clinical trial infrastructure further supplements the review. Searching yielded 818 titles and abstracts, of which 12 were suitable for this review. Results are summarised and presented narratively under the following headings: 1) identifying clinically relevant research questions; 2) education and training; 3) conduct of multicentre RCTs and 4) dissemination and adoption of trial results. This review confirms growing international awareness of the important role research networks play in supporting trials in orthopaedic surgery. Multidisciplinary collaboration and adequate investment in trial infrastructure are crucial for successful delivery of RCTs.

    Nakamura, Hiroshige; Suda, Takashi; Ikeda, Norihiko; Okada, Morihito; Date, Hiroshi; Oda, Makoto; Iwasaki, Akinori


    As surgical robots have become increasingly used, verification of their usefulness in the general thoracic surgery field is required. Initial results of robot-assisted thoracoscopic surgery in Japan were investigated. A questionnaire survey was performed to retrospectively examine the current status of robotic surgery for general thoracic disease in Japan. The subjects were 112 cases performed by the end of September 2012 at 9 institutions. There were 60 cases of primary lung cancer, 38 cases of anterior-middle mediastinal disease, and 14 cases of posterior mediastinal disease. In lung cancer cases, the operative time was 284.7 min, the blood loss was 129 mL, the drainage period was 3.3 days, and the conversion rate was 3.3 %. The incidence of postoperative complications was 6.7 %. The postoperative hospital stay was 8.2 days. In cases of anterior-middle mediastinal disease, the operative time was 184.3 min, the blood loss was 43.8 mL, the drainage period was 2.3 days, and there was no conversion. The incidence of postoperative complications was 7.9 %. The postoperative hospital stay was 7.1 days. In cases of posterior mediastinal disease, the operative time was 142.6 min, the blood loss was 61.4 mL, the drainage period was 1.6 days, and there was no conversion. No postoperative complication developed in any case. The postoperative hospital stay was 5 days. In all cases underwent robotic surgery, there was no operation related mortality. Robotic surgery was safely introduced, and the incidence of postoperative complications tended to be low, although the operative time was long. Preparations for its employment in advanced medical care and coverage by national health insurance are urgent issue.

  13. [Impact of digital technology on clinical practices: perspectives from surgery]. (United States)

    Zhang, Y; Liu, X J


    Digital medical technologies or computer aided medical procedures, refer to imaging, 3D reconstruction, virtual design, 3D printing, navigation guided surgery and robotic assisted surgery techniques. These techniques are integrated into conventional surgical procedures to create new clinical protocols that are known as "digital surgical techniques". Conventional health care is characterized by subjective experiences, while digital medical technologies bring quantifiable information, transferable data, repeatable methods and predictable outcomes into clinical practices. Being integrated into clinical practice, digital techniques facilitate surgical care by improving outcomes and reducing risks. Digital techniques are becoming increasingly popular in trauma surgery, orthopedics, neurosurgery, plastic and reconstructive surgery, imaging and anatomic sciences. Robotic assisted surgery is also evolving and being applied in general surgery, cardiovascular surgery and orthopedic surgery. Rapid development of digital medical technologies is changing healthcare and clinical practices. It is therefore important for all clinicians to purposefully adapt to these technologies and improve their clinical outcomes.

  14. Factors Associated with Gender-Affirming Surgery and Age of Hormone Therapy Initiation Among Transgender Adults (United States)

    Beckwith, Noor; Reisner, Sari L.; Zaslow, Shayne; Mayer, Kenneth H.; Keuroghlian, Alex S.


    Abstract Purpose: Gender-affirming surgeries and hormone therapy are medically necessary treatments to alleviate gender dysphoria; however, significant gaps exist in the research and clinical literature on surgery utilization and age of hormone therapy initiation among transgender adults. Methods: We conducted a retrospective review of electronic health record data from a random sample of 201 transgender patients of ages 18–64 years who presented for primary care between July 1, 2010 and June 30, 2015 (inclusive) at an urban community health center in Boston, MA. Fifty percent in our analyses were trans masculine (TM), 50% trans feminine, and 24% reported a genderqueer/nonbinary gender identity. Regression models were fit to assess demographic, gender identity-related, sexual history, and mental health correlates of gender-affirming surgery and of age of hormone therapy initiation. Results: Overall, 95% of patients were prescribed hormones by their primary care provider, and the mean age of initiation of masculinizing or feminizing hormone prescriptions was 31.8 years (SD=11.1). Younger age of initiation of hormone prescriptions was associated with being TM, being a student, identifying as straight/heterosexual, having casual sexual partners, and not having past alcohol use disorder. Approximately one-third (32%) had a documented history of gender-affirming surgery. Factors associated with increased odds of surgery were older age, higher income levels, not identifying as bisexual, and not having a current psychotherapist. Conclusion: This study extends our understanding of prevalence and factors associated with gender-affirming treatments among transgender adults seeking primary care. Findings can inform future interventions to expand delivery of clinical care for transgender patients. PMID:29159310

  16. Clinical implications of medulloblastoma subgroups: incidence of CSF diversion surgery. (United States)

    Schneider, Christian; Ramaswamy, Vijay; Kulkarni, Abhaya V; Rutka, James T; Remke, Marc; Tabori, Uri; Hawkins, Cynthia; Bouffet, Eric; Taylor, Michael D


    While medulloblastoma was initially thought to comprise a single homogeneous entity, it is now accepted that it in fact comprises 4 discrete subgroups, each with its own distinct demographics, clinical presentation, transcriptomics, genetics, and outcome. Hydrocephalus is a common complication of medulloblastoma and not infrequently requires CSF diversion. The authors report the incidence of CSF diversion surgery in each of the subgroups of medulloblastoma (Wnt, Shh, Group 3, and Group 4). The medical and imaging records for patients who underwent surgery for medulloblastoma at The Hospital for Sick Children were retrospectively reviewed. The primary outcome was the requirement for CSF diversion surgery either before or within 60 days of tumor resection. The modified Canadian Preoperative Prediction Rule for Hydrocephalus (mCPPRH) was compared among subgroups. Of 143 medulloblastoma patients, treated from 1991 to 2013, sufficient data were available for 130 patients (15 with Wnt, 30 with Shh, 30 with Group 3, and 55 with Group 4 medulloblastomas). Of these, 28 patients (22%) ultimately underwent CSF diversion surgery: 0% with Wnt, 29% with Shh, 29% with Group 3, and 43% with Group 4 tumors. Patients in the Wnt subgroup had a lower incidence of CSF diversion than all other patients combined (p = 0.04). Wnt patients had a lower mCPPRH score (lower risk of CSF diversion, p = 0.045), were older, had smaller ventricles at diagnosis, and had no leptomeningeal metastases. The overall rate of CSF diversion surgery for Shh, Group 3, and Group 4 medulloblastomas is around 30%, but no patients in the present series with a Wnt medulloblastoma required shunting. The low incidence of hydrocephalus in patients with Wnt medulloblastoma likely reflects both host factors (age) and disease factors (lack of metastases). The absence of hydrocephalus in patients with Wnt medulloblastomas likely contributes to their excellent rate of survival and may also contribute to a higher quality

    Intestinal complications of stenosis or fistula may occur during the course of Crohn's disease (CD), and surgery is performed in a fair number of patients. The risk factors for initial surgery in a Japanese hospital-based cohort of CD patients were evaluated. This study was a single-center, retrospective, cohort study. The subjects were 520 patients who underwent inpatient and outpatient treatment at our hospital, had a definitive diagnosis of CD, and no previous surgery. Three parameters were investigated: (i) cumulative incidence of stenosis and fistula; (ii) cumulative rate of initial surgery for each disease type; and (iii) risk factors at diagnosis for initial surgery. (i) Stenosis and fistula increased with time, with stenosis or fistula appearing in about half of the patients after 5 years. (ii) The cumulative rate of initial surgery was about 50% after 10 years. (iii) The patient factors at diagnosis of current smoker, upper gastrointestinal disease, stricturing, penetrating, moderate to severe stenosis of the jejunum, moderate to severe stenosis of the ileum, and moderate to severe stenosis of the terminal ileum were risk factors for initial surgery. Stenosis or fistula appeared in about half of the patients after 5 years from diagnosis. When upper gastrointestinal disease or complicated small intestinal lesions are seen at the time of diagnosis, the cumulative rate of initial surgery is significantly higher. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

  18. Factors influencing career choice after initial training in surgery.

    LENUS (Irish Health Repository)

    McHugh, Seamus


    INTRODUCTION: Irish general surgery faces a recruitment crisis with only 87 of 145 (60%) basic surgical training (BST) places filled in 2009. We assessed basic surgical trainees to identify objective, and potentially modifiable, factors that influence ultimate recruitment into a general surgical career. METHODS: Candidates commencing BST training during a 5-year period between 2004 and 2008 were included in a quantitative study. In addition a total of 2,536 candidates, representing all those who commenced surgical training in Ireland since 1960 were identified through the Royal College of Surgeons in Ireland (RCSI) database and invited to complete an online survey. Statistical analysis was performed using SPSS version 15, with p < 0.05 considered significant. RESULTS: During the 5-year quantitative study period there were 381 BST trainees. Gender was a significant predictor of career choice with women more likely to ultimately choose a nonsurgical career after initial surgical training (p = 0.049). Passing surgical membership examinations (MRCS) also was predictive of remaining in surgery (p = 0.005). Training region was not a significant predictor of ultimate career choice. There were 418 survey respondents. The influence of role models was most commonly cited as influencing candidates in choosing to commence surgical training. Candidates who rated "academic opportunity" (p = 0.023) and "intellectual challenge" (p = 0.047) as factors that influenced their decision to commence surgical training were more likely to ultimately continue their careers in a surgical speciality. CONCLUSIONS: This study describes the career pathway of surgical trainees and confirms the importance of academic achievement in discriminating between candidates applying for surgical training schemes.

    Directory of Open Access Journals (Sweden)

    Reşit Murat Açıkalın


    Full Text Available Aim: The aim of this study was to analyze the results of stapes surgery, which is done to improve the air-bone gap in otosclerosis, and to show its benefit in hearing. Methods: We retrospectively analyzed 42 patients in terms of audiologic evaluation results, smoking status, tinnitus and complications. Air-bone gap closure was classified as successful (gap 10 dB and unsuccessful (no gap closure or worse. Results: The mean preoperative air-bone gap was 37.43 dB. Air-bone gap closure was successful or partially successful in 39 patients (92.86% and unsuccessful in two patients (4.76. There was no relationship between the success of the surgery and smoking. All 42 had tinnitus preoperatively. Tinnitus healed in 28 patients postoperatively. One patient had tympanic membrane perforation postoperatively. Conclusion: Although there are some complications, stapes surgery in patients with otosclerosis is a reliable and effective option.

  1. Positron emission mammography: initial clinical results. (United States)

    Levine, Edward A; Freimanis, Rita I; Perrier, Nancy D; Morton, Kathryn; Lesko, Nadia M; Bergman, Simon; Geisinger, Kim R; Williams, Rodney C; Sharpe, Connie; Zavarzin, Valera; Weinberg, Irving N; Stepanov, Pavel Y; Beylin, David; Lauckner, Kathryn; Doss, Mohan; Lovelace, Judy; Adler, Lee P


    Evaluation of high-risk mammograms represents an enormous clinical challenge. Functional breast imaging coupled with mammography (positron emission mammography [PEM]) could improve imaging of such lesions. A prospective study was performed using PEM in women scheduled for stereotactic breast biopsy. Patients were recruited from the surgical clinic. Patients were injected with 10 mCi of 2-[18F] fluorodeoxyglucose. One hour later, patients were positioned on the stereotactic biopsy table, imaged with a PEM scanner, and a stereotactic biopsy was performed. Imaging was reviewed and compared with pathologic results. There were 18 lesions in 16 patients. PEM images were analyzed by drawing a region of interest at the biopsy site and comparing the count density in the region of interest with the background. A lesion-to-background ratio >2.5 appeared to be a robust indicator of malignancy and yielded a sensitivity of 86%, specificity of 91%, and overall diagnostic accuracy of 89%. No adverse events were associated with the PEM imaging. The data show that PEM is safe, feasible, and has an encouraging accuracy rate in this initial experience. Lesion-to-background ratios >2.5 were found to be a useful threshold value for identifying positive (malignant) results. This study supports the further development of PEM.

  2. Clinical innovations in Philippine thoracic surgery. (United States)

    Danguilan, Jose Luis J


    Thoracic surgery in the Philippines followed the development of thoracic surgery in the United States and Europe. With better understanding of the physiology of the open chest and refinements in thoracic anesthetic and surgical approaches, Filipino surgeons began performing thoracoplasties, then lung resections for pulmonary tuberculosis and later for lung cancer in specialty hospitals dealing with pulmonary diseases-first at the Quezon Institute (QI) and presently at the Lung Center of the Philippines although some university and private hospitals made occasional forays into the chest. Esophageal surgery began its early attempts during the post-World War II era at the Philippine General Hospital (PGH), a university hospital affiliated with the University of the Philippines. With the introduction of minimally invasive thoracic surgical approaches, Filipino thoracic surgeons have managed to keep up with their Asian counterparts although the problems of financial reimbursement typical of a developing country remain. The need for creative innovative approaches of a focused multidisciplinary team will advance the boundaries of thoracic surgery in the Philippines.

  3. Strategic laparoscopic surgery for improved cosmesis in general and bariatric surgery: analysis of initial 127 cases. (United States)

    Nguyen, Ninh T; Smith, Brian R; Reavis, Kevin M; Nguyen, Xuan-Mai T; Nguyen, Brian; Stamos, Michael J


    Strategic laparoscopic surgery for improved cosmesis (SLIC) is a less invasive surgical approach than conventional laparoscopic surgery. The aim of this study was to examine the feasibility and safety of SLIC for general and bariatric surgical operations. Additionally, we compared the outcomes of laparoscopic sleeve gastrectomy with those performed by the SLIC technique. In an academic medical center, from April 2008 to December 2010, 127 patients underwent SLIC procedures: 38 SLIC cholecystectomy, 56 SLIC gastric banding, 26 SLIC sleeve gastrectomy, 1 SLIC gastrojejunostomy, and 6 SLIC appendectomy. SLIC sleeve gastrectomy was initially performed through a single 4.0-cm supraumbilical incision with extraction of the gastric specimen through the same incision. The technique evolved to laparoscopic incisions that were all placed within the umbilicus and suprapubic region. There were no 30-day or in-hospital mortalities or 30-day re-admissions or re-operations. For SLIC cholecystectomy, gastric banding, appendectomy, and gastrojejunostomy, conversion to conventional laparoscopy occurred in 5.3%, 5.4%, 0%, and 0%, respectively; there were no major or minor postoperative complications. For SLIC sleeve gastrectomy, there were no significant differences in mean operative time and length of hospital stay compared with laparoscopic sleeve gastrectomy; 1 (3.8%) of 26 SLIC patients required conversion to five-port laparoscopy. There were no major complications. Minor complications occurred in 7.7% in the SLIC sleeve group versus 8.3% in the laparoscopic sleeve group. SLIC in general and bariatric operations is technically feasible, safe, and associated with a low rate of conversion to conventional laparoscopy. Compared with laparoscopic sleeve gastrectomy, SLIC sleeve gastrectomy can be performed without a prolonged operative time with comparable perioperative outcomes.

  4. Clinical assessment and management of general surgery patients via synchronous telehealth. (United States)

    Cain, Steven M; Moore, Robert; Sturm, Lauren; Mason, Travis; Fuhrman, Caitlin; Smith, Robin; Bojicic, Irfan; Carter, Brandon


    Objective This paper describes how a clinical team at Landstuhl Regional Medical Center (LRMC) successfully integrated synchronous telehealth (TH) into their routine clinical practice. Methods and materials Synchronous TH encounters were performed using Polycom® software on surgeons' computers with high-definition (HD) cameras on monitors at distant sites and PolyCom HDX9000® Telehealth Practitioner Carts at originating sites. Patients provided consented and were presented to general surgeons by nurses and medical technicians at Army health clinics throughout the European Theater. Results In calendar year (CY) 2014, five general surgeons and two surgical physician assistants (PAs) at Landstuhl Regional Medical Center along with registered nurses (RNs) at six originating clinic sites throughout Europe completed 130 synchronous TH encounters for 101 general surgery patients resulting in 73 completed and 16 recommended surgeries. Eighty-eight percent of patients had a completed or recommended surgery. No surgeries or procedures planned after initial TH evaluation were cancelled. Originating site clinics ranged in distance from 68 miles to 517 miles. Acceptance by providers, patients and clinic staff was high. Conclusion Synchronous TH was effective and safe in evaluating common general surgical conditions. We excluded sensitive and complex conditions requiring a nuanced physical examination. The TH efforts of the general surgery staff have resulted in high-quality, seamless and predictable TH activities that continue to expand into other surgical and medical specialties beyond general surgery. Seven surgeons and two PAs use synchronous TH regularly serving patients over a broad geographic area.

  5. Piezoelectric surgery in implant dentistry: clinical applications

    Directory of Open Access Journals (Sweden)

    Lydia Masako Ferreira


    Full Text Available Pizosurgery has therapeutic characteristics in osteotomies, such as extremely precise, selective and millimetric cuts and a clear operating field. Piezoelectricity uses ultrasonic frequencies, which cause the points specially designed for osteotomy to vibrate. The points of the instrument oscillate, allowing effective osteotomy with minimal or no injury to the adjacent soft tissues, membranes and nerve tissues. This article presents the various applications of piezoelectricity in oral implant surgery such as: removal of autogenous bone; bone window during elevation of the sinus membrane and removal of fractured implants. The cavitational effect caused by the vibration of the point and the spray of physiological solution, provided a field free of bleeding and easy to visualize. The study showed that the piezoelectric surgery is a new surgical procedurethat presents advantages for bone cutting in many situations in implant dentistry, with great advantages in comparison with conventional instrumentation. Operating time is longer when compared with that of conventional cutters.

    The objective of this study was to evaluate the safety and feasibility of robot-assisted thoracoscopic surgery (RATS). From May 2009 to May 2013, 48 patients with intrathoracic lesions underwent RATS with the da Vinci® Surgical System was reported (11 lobectomies, 37 mediastinal tumour resections). RATS was successfully and safely completed in all 48 patients. Conversion of the operation to open surgery was not needed in any patient. The average operation time was 85.9 min, average blood loss 33 ml, and average hospital stay 3.9 days. No patient required blood transfusion. The only recognized adverse event was the development of a bronchopleural fistula in one patient. RATS appears feasible and safe in thoracic surgery. More investigation will be needed in order to determine its possible long-term benefits and cost effectiveness. Copyright © 2014 John Wiley & Sons, Ltd.

  7. Complications in paediatric craniofacial surgery: an initial four year experience. (United States)

    Jones, B M; Jani, P; Bingham, R M; Mackersie, A M; Hayward, R


    107 children undergoing transcranial craniofacial surgery in a paediatric hospital have been reviewed to assess the incidence and type of complications which arose. This represents the first 4 years' experience of the craniofacial team. There were no deaths or permanent adverse sequelae of surgery. A total of 53 complications were seen in 42 patients. In 9.3% of patients they were potentially life-threatening, serious in 12.1% and of a minor nature in 28%. The more serious complications were related either to haemorrhage and/or vasovagal shock at operation or to infection post-operatively. Infants undergoing monoblock frontofacial advancements and those with tracheostomies were at particular risk.

    Latella, G; Cocco, A; Angelucci, E; Viscido, A; Bacci, S; Necozione, S; Caprilli, R


    The severity of clinical activity of Crohn's disease is high during the first year after diagnosis and decreases thereafter. Approximately 50% of patients require steroids and immunosuppressants and 75% need surgery during their lifetime. The clinical course of patients with Crohn's disease first diagnosed at surgery has never been investigated. To assess the clinical course of Crohn's disease first diagnosed at surgery for acute abdomen and to evaluate the need for medical and surgical treatment in this subset of patients. Hospital clinical records of 490 consecutive Crohn's disease patients were reviewed. Patients were classified according to the Vienna criteria. Sex, extraintestinal manifestations, family history of inflammatory bowel diseases, appendectomy, smoking habit and medical/surgical treatments performed during the follow-up period were assessed. Kaplan-Meier survival method and Cox proportional hazards regression model. Of the 490 Crohn's disease patients, 115 had diagnosis of Crohn's disease at surgery for acute abdomen (Group A) and 375 by conventional clinical, radiological, endoscopic and histologic criteria (Group B). Patients in Group A showed a low risk of further surgery (Log Rank test pacute abdomen showed a low risk for reintervention and less use of steroids and immunosuppressants during follow-up than those not operated upon at diagnosis. Early surgery may represent a valid approach in the initial management of patients with Crohn's disease, at least in the subset of patients with ileal and complicated disease.

    The author comments on the care for patients victim of accidents with radioactive material. He analyses not only the procedures done in the treatment of skin injuries and prevention of complications, but principally the steps to be followed by all surgical team to deal with this special kind of patient. He puts emphasis in the fact that is necessary measuring radiation levels by specialized personnel during all the surgical act, and whenever there is a high level of radiation the drape, gloves, gowns should be changed and contaminated areas clean. The conclusion introduces procedures to be taken after surgery. (author)

    Irish general surgery faces a recruitment crisis with only 87 of 145 (60%) basic surgical training (BST) places filled in 2009. We assessed basic surgical trainees to identify objective, and potentially modifiable, factors that influence ultimate recruitment into a general surgical career.

  12. [Guidelines for clinical practice for bariatric surgery]. (United States)

    Ciangura, Cécile; Nocca, David; Lindecker, Valérie


    Bariatric surgery is intended for subjects with BMI ≥ 40 kg/m(2) or ≥ 35 kg/m(2) with comorbidities. In any case, the indication can only be envisaged in patients who have had access to specialized medical care, and agree with a prolonged medical follow-up. After 60 years old, physiological age and comorbidities need to be highly considered. In genetic obesity and craniopharyngioma, surgery is exceptional. Main contraindications consist in severe disorders in feeding behaviour, non-stabilized psychiatric disorders, alcoholism, drug addiction, inability to participate in prolonged medical follow-up. Surgical process includes many important stages: preparation and information by a multidisciplinary team (identify contraindication, give optimal information, look for and treat comorbidities [as sleep apneoas syndrome, diabetes, cardiopulmonary disease], assess nutritional and psychological status and feeding behaviour); the decision of intervention during a concerted analysis by a multidisciplinary team; follow-up (for life) led to screen for nutritional deficiencies and surgical complications, to reinforce diet and physical activity counselling, to adapt to new situations (as pregnancy), and advise psychological care if necessary.

  13. [Implementation of a department of plastic surgery in a university clinic for trauma surgery]. (United States)

    von Dercks, N; Fakler, J; Langer, S; Josten, C


    Since May 2012 plastic surgery for trauma patients at the University Hospital Leipzig is provided by an autonomous department. This study analyzed the effect of plastic surgery on the changes in diagnosis-related groups (DRG) at a clinic for trauma surgery. Within the first 2 years 37 patients (29 male and 8 female of which 38 were inpatient cases) were admitted to the clinic for trauma surgery and additionally received plastic surgery treatment. The appropriate DRG assignment as well as associated codes and revenues were recorded and compared with and without plastic surgery. A total of 261 operations were performed on these patients of which 71 were performed by the department of plastic surgery. The mean revenue was 22,156.44 EUR±20,578.22 EUR with a mean cost weighting of 7.2±6.7. Excluding plastic surgery treatment the mean revenue was 19,378.44 EUR±20,688.40 EUR and the mean cost weighting was 6.3±6.7. Thus, additional proceeds by the plastic surgery treatment were 2778.00 EUR±3857.01 EUR per case. The mean increase of the cost weighting was 0.9±1.3. A change of the DRG grouping occurred in 20 out of 38 cases treated. The mean length of stay (LoS) was 40.2±26.6 days. In the first year this was 17.9±22.4 days more than the mean national LoS of the appropriate DRG and 10.9±19.3 days in the second year. This means an average cost reduction of 4774.59 EUR per case. The implementation of a department for plastic surgery increased the revenues. Additional profits should be achieved by process enhancement and not by prolonged LoS.

    Nakamori, Kenji; Tomihara, Kei; Noguchi, Makoto


    Surgical extraction of the third molar is the most commonly performed surgical procedure in the clinical practice of oral surgery. Third molar surgery is warranted when there is inadequate space for eruption, malpositioning, or risk for cyst or odontogenic tumor formation. Preoperative assessment should include a detailed morphologic analysis of the third molar and its relationship to adjacent structures and surrounding tissues. Due to developments in medical engineering technology, computed ...

    Agata Frask


    Full Text Available The aim of this review was to assess the results of published experience with bariatric SILS surgery, with a particular focus on treatment feasibility and safety. An EMBASE and MEDLINE database search was performed identifying 13 articles totalling 87 patients in the laparoscopic adjustable gastric banding (LAGB group, 10 patients in the laparoscopic sleeve gastrectomy (LSG group, and 1 patient in the Roux-en-Y SILS group. In most series the learning curve was steep and operating times halved with time, reaching 53 min for LAGB and 90 min for LSG. In single case reports using strict selection criteria patients were discharged up to 24 hours following surgery. Treatment safety was satisfactory. Only two studies reported some minor complications with rates of up to 9.8%, including port malposition, port site infection, and seroma or haematoma formation. There were no complications in other studies. LAGB, LSG and Roux-en-Y surgeries were feasible although technically demanding and difficult.

  16. Type A aortic dissection in Marfan syndrome: extent of initial surgery determines long-term outcome. (United States)

    Rylski, Bartosz; Bavaria, Joseph E; Beyersdorf, Friedhelm; Branchetti, Emanuela; Desai, Nimesh D; Milewski, Rita K; Szeto, Wilson Y; Vallabhajosyula, Prashanth; Siepe, Matthias; Kari, Fabian A


    Data on outcomes after Stanford type A aortic dissection in patients with Marfan syndrome are limited. We investigated the primary surgery and long-term results in patients with Marfan syndrome who suffered aortic dissection. Among 1324 consecutive patients with aortic dissection type A, 74 with Marfan syndrome (58% men; median age, 37 years [first and third quartiles, 29 and 48 years]) underwent surgical repair (85% acute dissections; 68% DeBakey I; 55% composite valved graft, 30% supracoronary ascending replacement, 15% valve-sparing aortic root replacement; 12% total arch replacement; 3% in-hospital mortality) at 2 tertiary centers in the United States and Europe over the past 25 years. The rate of aortic reintervention with resternotomy was 24% (18 of 74) and of descending aorta (thoracic+abdominal) intervention was 30% (22 of 74) at a median follow-up of 8.4 years (first and third quartiles, 2.2 and 12.7 years). Freedom from need for aortic root reoperation in patients who underwent primarily a composite valved graft or valve-sparing aortic root replacement procedure was 95±3%, 88±5%, and 79±5% and in patients who underwent supracoronary ascending replacement was 83±9%, 60±13%, 20±16% at 5, 10, and 20 years. Secondary aortic arch surgery was necessary only in patients with initial hemi-arch replacement. Emergency surgery for type A dissection in patients with Marfan syndrome is associated with low in-hospital mortality. Failure to extend the primary surgery to aortic root or arch repair leads to a highly complex clinical course. Aortic root replacement or repair is highly recommended because supracoronary ascending replacement is associated with a high need (>40%) for root reintervention.

    Full Text Available Laparoscopic colorectal surgery is less traumatic when compared to traditional surgery techniques, with well-established advantages. The objective of this study was to report the experience in laparoscopic surgical treatment of colorectal diseases. METHOD: Catalog all patients submitted to laparoscopic colorectal surgery performed by one surgeon and perform a descriptive analysis of key data from these records. RESULTS: The study analyzed data from 43 patients who underwent laparoscopic colorectal surgery. Most were females (n=30; 69.77% in relation to males (n=13; 30.23%, mean age of 57.21 years old. Among the indications for surgery, diverticular disease was the most frequent (n=20; 46.51%, followed by malignancy (n=13; 30.23%. Most patients underwent rectosigmoidectomy (n=28; 65.12%, followed by right hemicolectomy (n=6; 13.95%, with conversions in five cases (11.63%. The study observed a tendency towards increased number of surgeries, reduced average operative time as well as decreased conversions to laparotomy along the studied period. CONCLUSION: Laparoscopic colorectal surgery is a safe procedure, and with the technical development of the team, the results have been increasingly good.A videolaparoscopia colorretal apresenta-se como uma tática operatória menos traumática com vantagens bem-estabelecidas.

  18. The Hispanic Clinic for Pediatric Surgery: A model to improve parent-provider communication for Hispanic pediatric surgery patients. (United States)

    Jaramillo, Joshua; Snyder, Elizabeth; Dunlap, Jonathan L; Wright, Robert; Mendoza, Fernando; Bruzoni, Matias


    26 million Americans have limited English proficiency (LEP). It is well established that language barriers adversely affect health and health care. Despite growing awareness of language barriers, there is essentially a void in the medical literature regarding the influence of language disparity on pediatric surgery patients. This study was designed to assess the impact of patient-provider language concordance on question-asking behavior and patient satisfaction for pediatric surgery patients. Participants included families of patients in a General Pediatric Surgery Clinic categorized into 3 groups by patient-provider language concordance: concordant English-speaking, LEP concordant Spanish-speaking, and LEP discordant Spanish-speaking using an interpreter. Clinical visits were audio recorded and the number of patient-initiated questions and the length of clinical encounter were measured. Families were administered a surgery-specific, 5-point Likert scale questionnaire modeled after validated surveys concerning communication, trust, perceived discrimination and patient-provider language concordance. Regression models were performed to analyze associations between language concordance and patient's question-asking behavior and between language concordance and survey results. A total of 156 participants were enrolled including 57 concordant-English, 52 LEP concordant-Spanish and 47 LEP-discordant-Spanish. There was significant variation in the mean number of patient-initiated questions among the groups (p=0.002). Both the English and Spanish concordant groups asked a similar number of questions (p=0.9), and they both asked more questions compared to the Spanish-discordant participants (p=0.002 and p=0.001). Language discordance was associated with fewer questions asked after adjustment for socioeconomic status. Language concordant participants rated higher scores of communication. Both Spanish-concordant and Spanish-discordant patients reported significantly increased

  19. Extraocular muscle surgery for extorsion after macular translocation surgery new surgical technique and clinical management. (United States)

    Holgado, Sandra; Enyedi, Laura B; Toth, Cynthia A; Freedman, Sharon F


    To report a new extraocular muscle surgery procedure for large-angle extorsion, and clinical management of subjective tilt and diplopia after full macular translocation (MT360). Consecutive retrospective case series. Seven patients with downward MT360 were evaluated after MT360, both before (preoperative) and after (postoperative) extraocular muscle surgery, with at least 6 months' follow-up. Information gathered included demographics, visual acuity, ocular motility, torsion by Maddox rod, ocular history, and symptoms of visual disturbance. Surgery on extraocular muscles was performed based on the magnitude of torsion measured after MT360 surgery. Maddox rod testing of torsion after MT360, and both preoperative and postoperative extraocular muscle surgery. Mean preoperative torsion was reduced from 45.4+/-11.3 degrees to 8.3+/-4.8 degrees (at 6 months after MT360) (P = 0.03). Extraocular muscle surgery slightly reduced the mean hypertropia of the operated eye (preoperative, 20+/-10 prism diopters [PD], vs. postoperative, 11+/-6 PD) (P = 0.06). Mean exotropia was affected minimally by extraocular muscle surgery (preoperative, 22+/-31 PD, vs. postoperative, 20+/-24 PD). Three patients required a second extraocular muscle surgery (performed on the fellow eye) to correct residual extorsion and diplopia. Overall, 85% (6/7) of patients were free of both diplopia and tilt after 1 or 2 extraocular muscle surgeries. Although our patients continued to have significant horizontal/vertical strabismus postoperatively, the extraocular muscle surgery performed was successful in reducing the torsional misalignment enough such that the remaining diplopia could be successfully ignored or suppressed.

  20. Initial axillary surgery: results from the BreastSurgANZ Quality Audit. (United States)

    Chong, Chilton; Walters, David; de Silva, Primali; Taylor, Corey; Spillane, Andrew; Kollias, James; Pyke, Chris; Campbell, Ian; Maddern, Guy


    The aim of this study was to establish the preference and reasons for initial axillary surgery performed on women with invasive breast cancer in Australia and New Zealand using data from the Breast Surgeon's Society of Australia and New Zealand Quality Audit (BQA) according to whether sentinel lymph node (SLN) biopsy, axillary lymph node dissection (ALND) or no axillary surgery was used. Patient data from 1999 to 2011 were categorized according to primary tumour size (≤3 cm or >3 cm) and analysed by year of diagnosis, type of initial axillary surgery and frequency of second axillary surgery following SLN biopsy. Patient age at diagnosis, health insurance status, surgeon caseload and hospital location were also examined as factors affecting the likelihood of performing different types of axillary surgery. Seventy thousand six hundred and eighty-eight episodes of early breast cancer with axillary surgery data were reported to the BQA in the study period. The proportion of patients undergoing SLN biopsy as the first operation increased over this period in both tumour size groups with a concomitant decline in the use of ALND as the first operation over the same interval. Elderly women (>70 years old) were four times less likely to undergo axillary surgery for their initial management when compared with women aged 41-70 years old (P < 0.001). Factors favouring ALND as the initial surgery over SLN biopsy included larger tumour size, elderly age, uninsured status and having surgery in a regional centre. From 1999 to 2011, SLN biopsy as the initial axillary surgery has been widely adopted by surgeons reporting to the BQA. Future evaluation of the BQA data in the following 3-5 years will be performed to monitor this progression. © 2013 Royal Australasian College of Surgeons.

  2. Clinical significance of computed tomography assessment for third molar surgery. (United States)

    Nakamori, Kenji; Tomihara, Kei; Noguchi, Makoto


    Surgical extraction of the third molar is the most commonly performed surgical procedure in the clinical practice of oral surgery. Third molar surgery is warranted when there is inadequate space for eruption, malpositioning, or risk for cyst or odontogenic tumor formation. Preoperative assessment should include a detailed morphologic analysis of the third molar and its relationship to adjacent structures and surrounding tissues. Due to developments in medical engineering technology, computed tomography (CT) now plays a critical role in providing the clear images required for adequate assessment prior to third molar surgery. Removal of the maxillary third molar is associated with a risk for maxillary sinus perforation, whereas removal of the mandibular third molar can put patients at risk for a neurosensory deficit from damage to the lingual nerve or inferior alveolar nerve. Multiple factors, including demographic, anatomic, and treatment-related factors, influence the incidence of nerve injury during or following removal of the third molar. CT assessment of the third molar prior to surgery can identify some of these risk factors, such as the absence of cortication between the mandibular third molar and the inferior alveolar canal, prior to surgery to reduce the risk for nerve damage. This topic highlight presents an overview of the clinical significance of CT assessment in third molar surgery.

  3. Initial evaluation of a femtosecond laser system in cataract surgery. (United States)

    Chang, John S M; Chen, Ivan N; Chan, Wai-Man; Ng, Jack C M; Chan, Vincent K C; Law, Antony K P


    To report the early experience and complications during cataract surgery with a noncontact femtosecond laser system. Hong Kong Sanatorium and Hospital, Hong Kong Special Administrative Region, China. Retrospective case series. All patients had anterior capsulotomy or combined anterior capsulotomy and lens fragmentation using a noncontact femtosecond laser system (Lensar) before phacoemulsification. Chart and video reviews were performed retrospectively to determine the intraoperative complication rate. Risk factors associated with the complications were also analyzed. One hundred seventy eyes were included. Free-floating capsule buttons were found in 151 eyes (88.8%). No suction break occurred in any case. Radial anterior capsule tears occurred in 9 eyes (5.3%); they did not extend to the equator or posterior capsule. One eye (0.6%) had a posterior capsule tear. No capsular block syndrome developed, and no nuclei were dropped during irrigation/aspiration (I/A). Anterior capsule tags and miosis occurred in 4 eyes (2.4%) and 17 eyes (10.0%), respectively. Different severities of subconjunctival hemorrhages developed in 71 (43.8%) of 162 eyes after the laser procedure. The mean surgical time from the beginning to the end of suction was 6.72 minutes ± 4.57 (SD) (range 2 to 28 minutes). Cataract surgery with the noncontact femtosecond laser system was safe. No eye lost vision because of complications. Caution should be taken during phacoemulsification and I/A to avoid radial anterior capsule tears and posterior capsule tears.

    Mair, Tim


    "Clinical governance" is the term used to describe a systematic approach to maintaining and improving the quality of patient care within a health system. This article introduces the concept of clinical governance as a tool for improving the quality of care. It also discusses the potential value of a large database of colic surgery in implementing some of the components of clinical governance in the field of equine colic surgery.

  6. An initial experience with a digital drainage system during the postoperative period of pediatric thoracic surgery (United States)

    Costa, Altair da Silva; Bachichi, Thiago; Holanda, Caio; Rizzo, Luiz Augusto Lucas Martins De


    ABSTRACT Objective: To report an initial experience with a digital drainage system during the postoperative period of pediatric thoracic surgery. Methods: This was a prospective observational study involving consecutive patients, ≤ 14 years of age, treated at a pediatric thoracic surgery outpatient clinic, for whom pulmonary resection (lobectomy or segmentectomy via muscle-sparing thoracotomy) was indicated. The parameters evaluated were air leak (as quantified with the digital system), biosafety, duration of drainage, length of hospital stay, and complications. The digital system was used in 11 children (mean age, 5.9 ± 3.3 years). The mean length of hospital stay was 4.9 ± 2.6 days, the mean duration of drainage was 2.5 ± 0.7 days, and the mean drainage volume was 270.4 ± 166.7 mL. The mean maximum air leak flow was 92.78 ± 95.83 mL/min (range, 18-338 mL/min). Two patients developed postoperative complications (atelectasis and pneumonia, respectively). The use of this digital system facilitated the decision-making process during the postoperative period, reducing the risk of errors in the interpretation and management of air leaks. PMID:28117476

  7. Benign prostatic hyperplasia: clinical treatment can complicate cataract surgery

    Directory of Open Access Journals (Sweden)

    Fernando Facio


    Full Text Available PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords "benign prostatic hyperplasia", "intraoperative floppy iris syndrome", "adrenergic alpha-antagonist" and "cataract surgery". In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2009. RESULTS: The first report of intraoperative floppy iris syndrome (IFIS was observed during cataract surgery in patients taking systemic alpha-1 AR antagonists in 2005. It has been most commonly seen related to use of tamsulosin. Changes of medication and washout periods of up to 2 weeks have been attempted to reduce the risk of complications in the setting of cataract surgery. CONCLUSION: Patients under clinical treatment for BPH should be informed about potential risks of this drug class so that it can be discuss with their healthcare providers, in particular urologist and ophthalmologist, prior to cataract surgery.

  8. Early surgery versus initial conservative treatment in patients with spontaneous supratentorial lobar intracerebral haematomas (STICH II): a randomised trial (United States)

    Mendelow, A David; Gregson, Barbara A; Rowan, Elise N; Murray, Gordon D; Gholkar, Anil; Mitchell, Patrick M


    Summary Background The balance of risk and benefit from early neurosurgical intervention for conscious patients with superficial lobar intracerebral haemorrhage of 10–100 mL and no intraventricular haemorrhage admitted within 48 h of ictus is unclear. We therefore tested the hypothesis that early surgery compared with initial conservative treatment could improve outcome in these patients. Methods In this international, parallel-group trial undertaken in 78 centres in 27 countries, we compared early surgical haematoma evacuation within 12 h of randomisation plus medical treatment with initial medical treatment alone (later evacuation was allowed if judged necessary). An automatic telephone and internet-based randomisation service was used to assign patients to surgery and initial conservative treatment in a 1:1 ratio. The trial was not masked. The primary outcome was a prognosis-based dichotomised (favourable or unfavourable) outcome of the 8 point Extended Glasgow Outcome Scale (GOSE) obtained by questionnaires posted to patients at 6 months. Analysis was by intention to treat. This trial is registered, number ISRCTN22153967. Findings 307 of 601 patients were randomly assigned to early surgery and 294 to initial conservative treatment; 298 and 291 were followed up at 6 months, respectively; and 297 and 286 were included in the analysis, respectively. 174 (59%) of 297 patients in the early surgery group had an unfavourable outcome versus 178 (62%) of 286 patients in the initial conservative treatment group (absolute difference 3·7% [95% CI −4·3 to 11·6], odds ratio 0·86 [0·62 to 1·20]; p=0·367). Interpretation The STICH II results confirm that early surgery does not increase the rate of death or disability at 6 months and might have a small but clinically relevant survival advantage for patients with spontaneous superficial intracerebral haemorrhage without intraventricular haemorrhage.

    Teertstra, Hendrik J.; Loo, Claudette E.; Bosch, Maurice A.A.J. van den; Muller, Sara H.; Gilhuijs, Kenneth G.A.; Tinteren, Harm van; Rutgers, Emiel J.T.


    The purpose of this study was to assess the potential value of tomosynthesis in women with an abnormal screening mammogram or with clinical symptoms. Mammography and tomosynthesis investigations of 513 woman with an abnormal screening mammogram or with clinical symptoms were prospectively classified according to the ACR BI-RADS criteria. Sensitivity and specificity of both techniques for the detection of cancer were calculated. In 112 newly detected cancers, tomosynthesis and mammography were each false-negative in 8 cases (7%). In the false-negative mammography cases, the tumor was detected with ultrasound (n=4), MRI (n=2), by recall after breast tomosynthesis interpretation (n=1), and after prophylactic mastectomy (n=1). Combining the results of mammography and tomosynthesis detected 109 cancers. Therefore in three patients, both mammography and tomosynthesis missed the carcinoma. The sensitivity of both techniques for the detection of breast cancer was 92.9%, and the specificity of mammography and tomosynthesis was 86.1 and 84.4%, respectively. Tomosynthesis can be used as an additional technique to mammography in patients referred with an abnormal screening mammogram or with clinical symptoms. Additional lesions detected by tomosynthesis, however, are also likely to be detected by other techniques used in the clinical work-up of these patients. (orig.)

  10. Predictors of Initial Levels and Trajectories of Anxiety in Women Prior to and For Six Months Following Breast Cancer Surgery (United States)

    Kyranou, Marianna; Puntillo, Kathleen; Dunn, Laura B.; Aouizerat, Bradley E.; Paul, Steven M.; Cooper, Bruce A.; Neuhaus, John; West, Claudia; Dodd, Marylin; Miaskowski, Christine


    Background The diagnosis of breast cancer in combination with the anticipation of surgery evokes fear, uncertainty, and anxiety in most women. Objective In patients who underwent breast cancer surgery, study purposes were to examine how ratings of state anxiety changed from the time of the preoperative assessment to 6 months after surgery and to investigate whether specific demographic, clinical, symptom, and psychosocial adjustment characteristics predicted the preoperative levels of state anxiety and/or characteristics of the trajectories of state anxiety. Interventions/Methods Patients (n=396) were enrolled preoperatively and completed the Spielberger State Anxiety inventory monthly for six months. Using hierarchical linear modeling, demographic, clinical, symptom, and psychosocial adjustment characteristics were evaluated as predictors of initial levels and trajectories of state anxiety. Results Patients experienced moderate levels of anxiety prior to surgery. Higher levels of depressive symptoms and uncertainty about the future, as well as lower levels of life satisfaction, less sense of control, and greater difficulty coping predicted higher preoperative levels of state anxiety. Higher preoperative state anxiety, poorer physical health, decreased sense of control, and more feelings of isolation predicted higher state anxiety scores over time. Conclusions Moderate levels of anxiety persist in women for six months following breast cancer surgery. Implications for Practice Clinicians need to implement systematic assessments of anxiety to identify high risk women who warrant more targeted interventions. In addition, ongoing follow-up is needed in order to prevent adverse postoperative outcomes and to support women to return to their preoperative levels of function. PMID:24633334

    : The purpose of this study is to report our 2-year experience of performing endoscopic intracardiac procedures using the da Vinci Surgical System. Our teams at Kanazawa University and Tokyo Medical University groups began using the da Vinci Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA) in 2005. This series represents the first Japanese application of robotic technology for totally endoscopic open-heart surgery. : From January 2008 to February 2009, 10 patients (mean age: 46.8 ± 16.3 years, 70% women) underwent endoscopic atrial septal defect closure and resection of the left atrial myxoma using the da Vinci Surgical System and peripheral cardiopulmonary bypass technique. Of the 10 patients, nine were classified as New York Heart Association class II and 1 patient exhibited atrial arrhythmias. In addition, two patients required mitral valve plasty (n = 2) and tricuspid annuloplasty (n = 1). : Mean da Vinci Surgical System working time was 140.7 ± 57.4 minutes. Mean cardiopulmonary bypass and aortic cross clamp times were 103.1 ± 37.1 and 30.0 ± 16.9 minutes, respectively. There were no conversions to sternotomy or small thoracotomy. There were no hospital deaths. Mean intensive care unit and hospital stays were 1 day and 3.1 ± 0.3 days, respectively. All patients appreciated the cosmetic result and fast recovery. : Closed-chest atrial septal defect closure and myxoma resection performed using robotic techniques achieved excellent results and rapid postoperative recovery and provided an attractive cosmetic advantage over median sternotomy.

  12. Biochemical consequences of bariatric surgery for extreme clinical obesity. (United States)

    Sarker, Anita; Meek, Claire L; Park, Adrian


    Obesity, defined as a body mass index over 30 kg/m(2) for adults, poses a major healthcare challenge with important economic, personal and social consequences. Although public health measures, lifestyle change and pharmacological therapies have an important role in the management of obesity, patients with established morbid obesity (body mass index over 40 kg/m(2)) may also require bariatric surgery. Bariatric or metabolic surgery is associated with effective and enduring weight loss but is also known to improve glucose homeostasis, blood pressure and dyslipidaemia. Patients who have bariatric surgery need lifelong clinical follow-up to identify and prevent nutritional deficiencies and other complications. Clinical biochemistry laboratories have an important role in the nutritional assessment of obese patients and in the identification of complications following bariatric surgery. The aim of this article is to review the different bariatric procedures available and to summarize their complications, especially nutrient deficiencies and those of particular relevance to clinical biochemistry laboratories. © The Author(s) 2015.

  13. Initial experience using a femtosecond laser cataract surgery system at a UK National Health Service cataract surgery day care centre. (United States)

    Day, Alexander C; Dhallu, Sandeep K; Maurino, Vincenzo; Wilkins, Mark R


    To describe the initial outcomes following installation of a cataract surgery laser system. National Health Service cataract surgery day care unit in North London, UK. 158 eyes of 150 patients undergoing laser-assisted cataract surgery. Laser cataract surgery using the AMO Catalys femtosecond laser platform. intraoperative complications including anterior and posterior capsule tears. docking to the laser platform, successful treatment delivery, postoperative visual acuities. Mean case age was 67.7±10.8 years (range 29-88 years). Docking was successful in 94% (148/158 cases), and in 4% (6/148 cases) of these, the laser delivery was aborted part way during delivery due to patient movement. A total of 32 surgeons, of grades from junior trainee to consultant, performed the surgeries. Median case number per surgeon was 3 (range from 1-20). The anterior capsulotomy was complete in 99.3% of cases, there were no anterior capsule tears (0%). There were 3 cases with posterior capsule rupture requiring anterior vitrectomy, and 1 with zonular dialysis requiring anterior vitrectomy (4/148 eyes, 2.7%). These 4 cases were performed by trainee surgeons, and were either their first laser cataract surgery (2 surgeons) or their first and second laser cataract surgeries (1 surgeon). Despite the learning curve, docking and laser delivery were successfully performed in almost all cases, and surgical complication rates and visual outcomes were similar to those expected based on national data. Complications were predominately confined to trainee surgeons, and with the exception of intraoperative pupil constriction appeared unrelated to the laser-performed steps.

  14. Clinical applications of gamma-detection probes - radioguided surgery

    International Nuclear Information System (INIS)

    Schneebaum, S.; Stadler, J.; Skornick, Y.


    Radioguided surgery (RGS) is a surgical technique that enables the surgeon to identify tissue ''marked'' by a radionuclide before surgery, based on the tissue characteristics, the radioactive tracer and its carrying molecule, or the affinity of both. Thus, yet another tool has been added to the inspection and palpation traditionally used by the surgeon. Current clinical applications of radioguided surgery are: radioimmunoguided surgery (RIGS) for colon cancer, sentinel-node mapping for malignant melanoma (which has become state-of-the-art), sentinel-node mapping for breast, vulvar and penile cancer, and detection of parathyroid adenoma and bone tumour (such as osteid osteoma). Although the same gamma-detecting probe (GDP) may be used for all these applications, the carrier substance and the radionuclide differ. MoAb and peptides are used for RIGS, sulphur colloid for sentinel-node mapping, iodine-125 for RIGS, technetium-99m for sentinel node, parathyroid and bone. The mode of injection also differs, but there are some common principles of gamma-guided surgery. RIGS enables the surgeon to corroborate tumour existence, find occult metastases, and assess the margins of resection; this may result in a change on the surgical plan. Sentinel lymph-node (SLN) scintigraphy for melanoma guides the surgeon to find the involved lymph nodes for lymph-node dissection. SLN for breast cancer is being investigated with promising results. This procedure has also changed the outlook of lymph-node pathology by giving the pathologist designated tissue samples for more comprehensive examination. Gamma-guided surgery will result in more accurate and less unnecessary surgery, better pathology and, hopefully, in better patient survival. (orig.)

  15. Vibration for Pain Reduction in a Plastic Surgery Clinic. (United States)

    Eichhorn, Mitchell George; Karadsheh, Murad Jehad; Krebiehl, Johanna Ruth; Ford, Dawn Marie; Ford, Ronald D


    Patients can experience significant pain during routine procedures in the plastic surgery clinic. Methods for clinical pain reduction are often impractical, time-consuming, or ineffective. Vibration is a safe, inexpensive, and highly applicable modality for pain reduction that can be readily utilized for a wide variety of procedures. This study evaluated the use of vibration as a viable pain-reduction strategy in the clinical plastic surgery setting. Patients requiring at least 2 consecutive procedures that are considered painful were enrolled in the study. These included injections, staple removal, and suture removal. In the same patient, one half of the procedures were performed without vibration and the other half with vibration. After completing the procedures, the patients rated their pain with vibration and without vibration. The patient and the researcher also described the experience with a short questionnaire. Twenty-eight patients were enrolled in the study. Patients reported significantly less pain on the Numeric Rating Scale pain scale when vibration was used compared with the control group (p reduction. It significantly reduces the pain experienced by patients during minor office procedures. Given its practicality and ease of use, it is a welcome tool in the plastic surgery clinic.

  16. Impact of bariatric surgery on clinical depression. Interrupted time series study with matched controls. (United States)

    Booth, Helen; Khan, Omar; Prevost, A Toby; Reddy, Marcus; Charlton, Judith; Gulliford, Martin C


    Obesity is associated with depression. This study aimed to evaluate whether clinical depression is reduced after bariatric surgery (BS). Obese adults who received BS procedures from 2002 to 2014 were sampled from the UK Clinical Practice Research Datalink. An interrupted time series design, with matched controls, was conducted from three years before, to a maximum of seven years after surgery. Controls were matched for body mass index (BMI), age, gender and year of procedure. Clinical depression was defined as a medical diagnosis recorded in year, or an antidepressant prescribed in year to a participant ever diagnosed with depression. Adjusted odds ratios (AOR) were estimated. There were 3045 participants (mean age 45.9; mean BMI 44.0kg/m(2)) who received BS, including laparoscopic gastric banding in 1297 (43%), gastric bypass in 1265 (42%), sleeve gastrectomy in 477 (16%) and six undefined. Before surgery, 36% of BS participants, and 21% of controls, had clinical depression; between-group AOR, 2.02, 95%CI 1.75-2.33, P<0.001. In the second post-operative year 32% had depression; AOR, compared to time without surgery, 0.83 (0.76-0.90, P<0.001). By the seventh year, the prevalence of depression increased to 37%; AOR 0.99 (0.76-1.29, P=0.959). Despite matching there were differences in depression between BS and control patients, representing the highly selective nature of BS. Depression is frequent among individuals selected to undergo bariatric surgery. Bariatric surgery may be associated with a modest reduction in clinical depression over the initial post-operative years but this is not maintained. Copyright © 2014 The Authors.

Methods: This was a prospective, non-randomized, observational, comparative cohort study in which Trabectome surgery was used alone in patients with POAG or EXG. Trabectome surgery was considered to have failed when at least one of the following three criteria was fulfilled: intraocular pressure (IOP ≥21 mmHg and a <20% reduction below the baseline IOP on two consecutive follow-up visits 3 months or more after surgery; need for additional glaucoma surgery; and an increase in number of medications compared with baseline. Results: The subjects were 32 males (34 eyes and 46 females (48 eyes. POAG was observed in 43 eyes and EXG in 39 eyes. IOP after Trabectome surgery decreased significantly from 22.3±6.8 mmHg at baseline to 14.0±3.9 mmHg (23.0% reduction at month 24 in all cases (P<0.0000. The success rate at 2 years was 51.2% for all cases (POAG, 50.9%; EXG, 49.2%. There was no significant difference in success rate between POAG and EXG (P=0.91. Preoperative IOP (P=0.033 and number of medications (P=0.041 were significant factors for surgical success/failure in multivariate logistic regression. No serious complications were observed. Conclusion: Trabectome surgery achieved favorable IOP control and was equally effective in patients with POAG and those with EXG. Its effects were influenced by preoperative IOP and number of preoperative medications. Keywords: Trabectome, primary open-angle glaucoma, exfoliation glaucoma, success rate, risk factors

  19. Plastic surgery training: evaluating patient satisfaction with facial fillers in a resident clinic. (United States)

    Iorio, Matthew L; Stolle, Ellen; Brown, Benjamin J; Christian, Cathalene Blake; Baker, Stephen B


    Resident cosmetic surgery clinics, or "chief clinics," are arguably the most effective way to provide cosmetic surgery training. Approximately 70 % of plastic surgery training programs utilize a "chief resident clinic" to augment their cosmetic surgery experience, even though a quantitative outcome scale is lacking to guide education. We report the use of the FACE-Q, a novel patient outcome tool, to evaluate patients' satisfaction with nonsurgical facial rejuvenation performed by residents. The FACE-Q "Satisfaction with Facial Appearance Overall Scale" was administered to patients prior to and 1 week after undergoing nonsurgical facial rejuvenation performed by plastic surgery residents. All patients received nonsurgical facial rejuvenation with botulinum toxin A and hyaluronic acid as part of resident facial aesthetics training. Eleven patients completed the pre- and postinjection FACE-Q survey. Average overall facial appearance satisfaction scores of 47.6 pre- and 51.1 postinjection were found (p < 0.037), with a total possible score of 68. Ten patients (91 %) reported feeling satisfied or very satisfied with the overall appearance of their face following injection. Despite resident inexperience and patient awareness that novices were performing the procedures, our experience supports use of the FACE-Q to optimize and endorse resident cosmetic surgery clinics. The learning curve for facial cosmetic procedures can be adversely affected by limited time available or exposure to improvement variables when initially performing the procedure. It is imperative to any technique that direct, and preferably quantitative, feedback is given so that an immediate modification can be generated and successive patient outcomes improved.

  20. [The clinical application of functional endoscopic sinus surgery and conventional technique in sinus surgery]. (United States)

    Zhang, X; Wang, Z; Wang, N


    To properly understand the basic theory and the clinical application of the functional endoscopic sinus surgery and the traditional technique. The indications, extend of excision, operative approach, complication and curative effect of 1,740 cases(3,140 sides) done in the China-Japan Friendship Hospital and Jining Jiaotong Hospital were analysed. Among them, 522 cases(1,032 sides, 30%) received the traditional technique for sinusitis; 1,218 cases(2,108 sides, 70%) received functional endoscopic sinus surgery. Three hundred and ninety-eight cases of traditional ethmoid sinus operation and 352 of functional sinus surgeries were followed-up and their cure rates were 80% and 93% respectively. Both groups had no serious complications. The main indications of functional sinus surgery are infectious nasal sinus diseases or meatus nasi lesion that may interfere with the drainage. Such kinds of diseases have high morbidity than the diffused polyposis and deserves attention. Traditional operations for frontal and maxillary sinusitis should be controlled appropriately, but the traditional sphenoid sinus operation is still an effective treatment for the diffused polyposis.

  1. Humidification during laparoscopic surgery: overview of the clinical benefits of using humidified gas during laparoscopic surgery. (United States)

    Binda, Maria Mercedes


    The peritoneum is the serous membrane that covers the abdominal cavity and most of the intra-abdominal organs. It is a very delicate layer highly susceptible to damage and it is not designed to cope with variable conditions such as the dry and cold carbon dioxide (CO2) during laparoscopic surgery. The aim of this review was to evaluate the effects caused by insufflating dry and cold gas into the abdominal cavity after laparoscopic surgery. A literature search using the Pubmed was carried out. Articles identified focused on the key issues of laparoscopy, peritoneum, morphology, pneumoperitoneum, humidity, body temperature, pain, recovery time, post-operative adhesions and lens fogging. Insufflating dry and cold CO2 into the abdomen causes peritoneal damage, post-operative pain, hypothermia and post-operative adhesions. Using humidified and warm gas prevents pain after surgery. With regard to hypothermia due to desiccation, it can be fully prevented using humidified and warm gas. Results relating to the patient recovery are still controversial. The use of humidified and warm insufflation gas offers a significant clinical benefit to the patient, creating a more physiologic peritoneal environment and reducing the post-operative pain and hypothermia. In animal models, although humidified and warm gas reduces post-operative adhesions, humidified gas at 32 °C reduced them even more. It is clear that humidified gas should be used during laparoscopic surgery; however, a question remains unanswered: to achieve even greater clinical benefit to the patient, at what temperature should the humidified gas be when insufflated into the abdomen? More clinical trials should be performed to resolve this query.

    Sara Socorro Faria


    Full Text Available INTRODUCTION: Optimum treatment for postoperative pain has been of fundamental importance in surgical patient care. Among the analgesic techniques aimed at this group of patients, thoracic paravertebral block combined with general anesthesia stands out for the good results and favorable risk-benefit ratio. Many local anesthetics and other adjuvant drugs are being investigated for use in this technique, in order to improve the quality of analgesia and reduce adverse effects. OBJECTIVE: Evaluate the effectiveness and safety of paravertebral block compared to other analgesic and anesthetic regimens in women undergoing breast cancer surgeries. METHODS: Integrative literature review from 1966 to 2012, using specific terms in computerized databases of articles investigating the clinical characteristics, adverse effects, and beneficial effects of thoracic paravertebral block. RESULTS: On the selected date, 16 randomized studies that met the selection criteria established for this literature review were identified. Thoracic paravertebral block showed a significant reduction of postoperative pain, as well as decreased pain during arm movement after surgery. CONCLUSION: Thoracic paravertebral block reduced postoperative analgesic requirement compared to placebo group, markedly within the first 24 h. The use of this technique could ensure postoperative analgesia of clinical relevance. Further studies with larger populations are necessary, as paravertebral block seems to be promising for preemptive analgesia in breast cancer surgery.

  4. [Support Team for Investigator-Initiated Clinical Research]. (United States)

    Fujii, Hisako


    Investigator-initiated clinical research is that in which investigators plan and carry out their own clinical research in academia. For large-scale clinical research, a team should be organized and implemented. This team should include investigators and supporting staff, who will promote smooth research performance by fulfilling their respective roles. The supporting staff should include project managers, administrative personnel, billing personnel, data managers, and clinical research coordinators. In this article, I will present the current status of clinical research support and introduce the research organization of the Dominantly Inherited Alzheimer Network (DIAN) study, an investigator-initiated international clinical research study, with particular emphasis on the role of the project management staff and clinical research coordinators.

  5. Progress in clinical research in surgery and IDEAL. (United States)

    McCulloch, Peter; Feinberg, Joshua; Philippou, Yiannis; Kolias, Angelos; Kehoe, Sean; Lancaster, Gillian; Donovan, Jenny; Petrinic, Tatjana; Agha, Riaz; Pennell, Christopher


    The quality of clinical research in surgery has long attracted criticism. High-quality randomised trials have proved difficult to undertake in surgery, and many surgical treatments have therefore been adopted without adequate supporting evidence of efficacy and safety. This evidence deficit can adversely affect research funding and reimbursement decisions, lead to slow adoption of innovations, and permit widespread adoption of procedures that offer no benefit, or cause harm. Improvement in the quality of surgical evidence would therefore be valuable. The Idea, Development, Exploration, Assessment, and Long-term Follow-up (IDEAL) Framework and Recommendations specify desirable qualities for surgical studies, and outline an integrated evaluation pathway for surgery, and similar complex interventions. We used the IDEAL Recommendations to assess methodological progress in surgical research over time, assessed the uptake and influence of IDEAL, and identified the challenges to further methodological progress. Comparing studies from the periods 2000-04 and 2010-14, we noted apparent improvement in the use of standard outcome measures, adoption of Consolidated Standards of Reporting Trials (CONSORT) standards, and assessment of the quality of surgery and of learning curves, but no progress in the use of qualitative research or reporting of modifications during procedure development. Better education about research, integration of rigorous evaluation into routine practice and training, and linkage of such work to awards systems could foster further improvements in surgical evidence. IDEAL has probably contributed only slightly to the improvements described to date, but its uptake is accelerating rapidly. The need for the integrated evaluation template IDEAL offers for surgery and other complex treatments is becoming more widely accepted. Copyright © 2018 Elsevier Ltd. All rights reserved.

  6. Laparoscopic pectopexy: initial experience of single center with a new technique for apical prolapse surgery

    Directory of Open Access Journals (Sweden)

    Ahmet Kale

    Full Text Available ABSTRACT Objective: To share our first experience with laparoscopic pectopexy, a new technique for apical prolapse surgery, and to evaluate the feasibility of this technique. Materials and Methods: Seven patients with apical prolapse underwent surgery with laparoscopic pectopexy. The lateral parts of the iliopectineal ligament were used for a bilateral mesh fixation of the descended structures. The medical records of the patients were reviewed, and the short-term clinical outcomes were analyzed. Results: The laparoscopic pectopexy procedures were successfully performed, without intraoperative and postoperative complications. De novo apical prolapse, de novo urgency, de novo constipation, stress urinary incontinence, anterior and lateral defect cystoceles, and rectoceles did not occur in any of the patients during a 6-month follow-up period. Conclusion: Although laparoscopic sacrocolpopexy has shown excellent anatomical and functional long-term results, laparoscopic pectopexy offers a feasible, safe, and comfortable alternative for apical prolapse surgery. Pectopexy may increase a surgeon's technical perspective for apical prolapse surgery.

  7. Bariatric Surgery in the United Kingdom: A Cohort Study of Weight Loss and Clinical Outcomes in Routine Clinical Care (United States)

    Douglas, Ian J.; Bhaskaran, Krishnan; Batterham, Rachel L.; Smeeth, Liam


    Background Bariatric surgery is becoming a more widespread treatment for obesity. Comprehensive evidence of the long-term effects of contemporary surgery on a broad range of clinical outcomes in large populations treated in routine clinical practice is lacking. The objective of this study was to measure the association between bariatric surgery, weight, body mass index, and obesity-related co-morbidities. Methods and Findings This was an observational retrospective cohort study using data from the United Kingdom Clinical Practice Research Datalink. All 3,882 patients registered in the database and with bariatric surgery on or before 31 December 2014 were included and matched by propensity score to 3,882 obese patients without surgery. The main outcome measures were change in weight and body mass index over 4 y; incident diagnoses of type 2 diabetes mellitus (T2DM), hypertension, angina, myocardial infarction (MI), stroke, fractures, obstructive sleep apnoea, and cancer; mortality; and resolution of hypertension and T2DM. Weight measures were available for 3,847 patients between 1 and 4 mo, 2,884 patients between 5 and 12 mo, and 2,258 patients between 13 and 48 mo post-procedure. Bariatric surgery patients exhibited rapid weight loss for the first four postoperative months, at a rate of 4.98 kg/mo (95% CI 4.88–5.08). Slower weight loss was sustained to the end of 4 y. Gastric bypass (6.56 kg/mo) and sleeve gastrectomy (6.29 kg/mo) were associated with greater initial weight reduction than gastric banding (2.77 kg/mo). Protective hazard ratios (HRs) were detected for bariatric surgery for incident T2DM, 0.68 (95% CI 0.55–0.83); hypertension, 0.35 (95% CI 0.27–0.45); angina, 0.59 (95% CI 0.40–0.87);MI, 0.28 (95% CI 0.10–0.74); and obstructive sleep apnoea, 0.55 (95% CI 0.40–0.87). Strong associations were found between bariatric surgery and the resolution of T2DM, with a HR of 9.29 (95% CI 6.84–12.62), and between bariatric surgery and the resolution of

  8. Routine clinical application of virtual reality in abdominal surgery. (United States)

    Sampogna, Gianluca; Pugliese, Raffaele; Elli, Marco; Vanzulli, Angelo; Forgione, Antonello


    The advantages of 3D reconstruction, immersive virtual reality (VR) and 3D printing in abdominal surgery have been enunciated for many years, but still today their application in routine clinical practice is almost nil. We investigate their feasibility, user appreciation and clinical impact. Fifteen patients undergoing pancreatic, hepatic or renal surgery were studied realizing a 3D reconstruction of target anatomy. Then, an immersive VR environment was developed to import 3D models, and some details of the 3D scene were printed. All the phases of our workflow employed open-source software and low-cost hardware, easily implementable by other surgical services. A qualitative evaluation of the three approaches was performed by 20 surgeons, who filled in a specific questionnaire regarding a clinical case for each organ considered. Preoperative surgical planning and intraoperative guidance was feasible for all patients included in the study. The vast majority of surgeons interviewed scored their quality and usefulness as very good. Despite extra time, costs and efforts necessary to implement these systems, the benefits shown by the analysis of questionnaires recommend to invest more resources to train physicians to adopt these technologies routinely, even if further and larger studies are still mandatory.

  9. Progressive Surgical Autonomy in a Plastic Surgery Resident Clinic (United States)

    Scott, Jillian K.; Gao, Lani; Lee, Tara M.; Waldrop, Jimmy L.; Sargent, Larry A.; Kennedy, J. Woody; Rehm, Jason P.; Brzezienski, Mark A.


    Background: Resident clinics are thought to catalyze educational milestone achievement through opportunities for progressively autonomous surgical care, but studies are lacking for general plastic surgery resident clinics (PSRCs). We demonstrate the achievement of increased surgical autonomy and continuity of care in a PSRC. Methods: A retrospective review of all patients seen in a PSRC from October 1, 2010, to October 1, 2015, was conducted. Our PSRC is supervised by faculty plastic surgery attendings, though primarily run by chief residents in an accredited independent plastic surgery training program. Surgical autonomy was scored on a 5-point scale based on dictated operative reports. Graduated chief residents were additionally surveyed by anonymous online survey. Results: Thousand one hundred forty-four patients were seen in 3,390 clinic visits. Six hundred fifty-three operations were performed by 23 total residents, including 10 graduating chiefs. Senior resident autonomy averaged 3.5/5 (SD = 1.5), 3.6/5 (SD = 1.5), to 3.8/5 (SD = 1.3) in postgraduate years 6, 7, and 8, respectively. A linear mixed model analysis demonstrated that training level had a significant impact on operative autonomy when comparing postgraduate years 6 and 8 (P = 0.026). Graduated residents’ survey responses (N = 10; 100% response rate) regarded PSRC as valuable for surgical experience (4.1/5), operative autonomy (4.4/5), medical knowledge development (4.7/5), and the practice of Accreditation Council of Graduate Medical Education core competencies (4.3/5). Preoperative or postoperative continuity of care was maintained in 93.5% of cases. Conclusion: The achievement of progressive surgical autonomy may be demonstrated within a PSRC model. PMID:28607848

  10. Evidence-based use of pulsed electromagnetic field therapy in clinical plastic surgery. (United States)

    Strauch, Berish; Herman, Charles; Dabb, Richard; Ignarro, Louis J; Pilla, Arthur A


    The initial development of pulsed electromagnetic field (PEMF) therapy and its evolution over the last century for use in clinical surgery has been slow, primarily because of lack of scientifically-derived, evidence-based knowledge of the mechanism of action. Our objective was to review the major scientific breakthroughs and current understanding of the mechanism of action of PEMF therapy, providing clinicians with a sound basis for optimal use. A literature review was conducted, including mechanism of action and biologic and clinical studies of PEMF. Using case illustrations, a holistic exposition on the clinical use of PEMF in plastic surgery was performed. PEMF therapy has been used successfully in the management of postsurgical pain and edema, the treatment of chronic wounds, and in facilitating vasodilatation and angiogenesis. Using scientific support, the authors present the currently accepted mechanism of action of PEMF therapy. This review shows that plastic surgeons have at hand a powerful tool with no known side effects for the adjunctive, noninvasive, nonpharmacologic management of postoperative pain and edema. Given the recent rapid advances in development of portable and economical PEMF devices, what has been of most significance to the plastic surgeon is the laboratory and clinical confirmation of decreased pain and swelling following injury or surgery.

    Full Text Available This was a retrospective review of a consecutive series of patients with spinal disease in year 2000, who underwent posterior fusion and instrumentation with Harrington distraction and Cotrel-Dobousset system to evaluate causes of hardware failure. Many cases of clinical failure has been observed in spinal instrumentation used in spinal disorder like spondylolisthesis, fractures, deformities, … . Thirty six cases that were operated because of spinal disorders like spondylolisthesis, fractures, deformities, …, were included in this study. Seventeen of this cases had breakage of device. Factors like age at surgery, type of instrumentation, angles before and after surgery and …, were compared in two groups of patients. The most common instrument breakage was pedicle screw breakage. Pseudoarthrosis was the main factor that was presented in failure group (P value<0.001. Other important causes were, age of patient at surgery (P value=0.04, pedicle screw placement off center in the sagittal or coronal plane of the pedicle (P value=0.04. Instrumentation loads increased significantly as a direct result of variations in surgical technique that produce pseudoarthrosis, pedicle screw placement off center in the sagittal plane of the pedicle, or using less than 6 mm diameter screw. This factor can be prevented with meticulous surgical technique and using proper devices.

    Predin Tanja


    Full Text Available Introduction. Periodontitis is a destructive inflammatory disease of the tooth-supporting tissues, primarily caused by Gram-negative microorganisms. Thus, the primary objective of cause-related initial periodontal therapy is disruption and removal of the subgingival biofilm. Objective. The aim of this study was to evaluate the clinical and microbiological effects of the initial therapy in patients diagnosed with chronic periodontitis. Methods. Forty patients with chronic periodontitis were included in the study. As a part of the clinical assessment undertaken prior to the initial therapy, as well as one month and three months post-therapy, plaque index, gingival index, papilla bleeding index, probing pocket depth and clinical attachment level were recorded. Microbiological testing was performed prior to the initial therapy and three months after therapy. Polymerase chain reaction assays were used to determine the presence of Porphyromonas gingivalis, Tannerella forsythensis, Prevotella intermedia and Aggregatibacter actinomycetemcomitans. Results. All clinical parameters were significantly reduced after therapy. The prevalence of Aggregatibacter actinomycetemcomitans was reduced by 22.5%, which was a statistically significant decrease compared to the baseline. The prevalence of Porphyromonas gingivalis, Tannerella forsythensis and Prevotella intermedia tended to decrease after therapy; however, the difference did not reach statistical significance. Conclusion. The results of the present study demonstrated the beneficial effects of the initial periodontal therapy on both the clinical and microbiological parameters.

    Yasuhiro Sumino


    Full Text Available Laparoendoscopic single-site surgery (LESS is a step toward the development of minimally invasive surgery. It is initially difficult for surgeons with limited experience to perform the surgery. We describe two cases of left adrenalectomy with a LESS combined with the addition of an accessory port. After a 2.5-cm skin incision was made at the level of the paraumbilicus to insert the primary 12-mm trocar for the laparoscope, a 5-mm nonbladed trocar was placed through the skin incision side-by-side with the primary trocar. A second 3-mm nonbladed trocar was then placed along the anterior axillary line; a multichannel trocar was not used as a single port. Both adrenalectomies were completed successfully. In patients with a minor adrenal tumor, a combined technique using LESS and an additional port is easier than LESS alone and may, therefore, be a bridge between the conventional laparoscopic approach and LESS.

    Corneli, Amy; Hallinan, Zachary; Hamre, Gerrit; Perry, Brian; Goldsack, Jennifer C; Calvert, Sara B; Forrest, Annemarie


    The mission of the Clinical Trials Transformation Initiative, a public-private partnership co-founded by the U.S. Food and Drug Administration and Duke University, is to develop and drive adoption of practices that will increase the quality and efficiency of clinical trials. The Clinical Trials Transformation Initiative works collaboratively with key stakeholders, implements "fit-for-purpose" evidence-gathering projects, and develops actionable recommendations and tools to address the challenges faced by the clinical trials enterprise. In pursuit of its mission, The Clinical Trials Transformation Initiative follows an innovative and collaborative, five-step methodology: (1) state the problem and identify impediments to research, (2) gather evidence to identify gaps and barriers, (3) explore results by analyzing and interpreting findings, (4) finalize solutions by developing recommendations and tools, and (5) drive adoption through disseminating and implementing recommendations and tools. This article describes each step of the Clinical Trials Transformation Initiative's methodology, with a specific focus on describing the evidence-gathering activities.

  15. Clinical impact of oncoplastic surgery in a specialist breast practice. (United States)

    Kollias, James; Davies, Giles; Bochner, Melissa A; Gill, Peter G


    Oncoplastic breast surgery is an integral and fundamental component of the clinical management of breast cancer. The aim of this study was to determine the proportion of oncoplastic and reconstructive breast cancer procedures undertaken within a specialist breast practice. An audit of breast-related cancer procedures was undertaken for patients with early breast cancer between 1 January 2001 and 31 December 2005, treated at the Royal Adelaide Hospital and in private practice. The proportion of oncoplastic and breast reconstructive procedures was calculated to determine the clinical effects on a specialist breast-surgical practice. Breast cancer resection procedures accounted for 1514 of 2113 of operations (72%). Most of these (897 of 1514, 59.2%) were wide local excision or re-excision procedures. Total breast reconstruction operations (i.e. autogenous tissue flaps, tissue expander/implant reconstructions) accounted for 251 procedures. Of these, 67 (26.7%) were carried out at the time of simple mastectomy. Contralateral breast procedures (i.e. reduction mammaplasty, mastopexy and augmentation) accounted for 138 procedures and nipple-areola reconstruction/tattoo accounted for 153 procedures. Oncoplastic procedures, such as skin-sparing mastectomy, latissimus dorsi miniflap and therapeutic mammaplasty accounted for 57 of 599 procedures (9.5%). Breast reconstruction and oncoplastic operations accounted for 599 of 2113 procedures (28%). Specialist breast surgeons trained in breast reconstruction and oncoplastic techniques can expect a substantial proportion of their breast practice to include such operative procedures (28% in this series). Subspecialist training in breast surgery should incorporate experience in breast reconstructive and aesthetic surgery for trainees who wish to practise as specialist breast surgeons in the future.

  16. [Pulmonary Metastasis from a Phyllodes Tumor of the Breast Developing Sixteen Years after Initial Surgery]. (United States)

    Chang, Sung-Soo; Nakano, Takayuki; Okamoto, Taku; Takabatake, Daisuke


    We report a case of solitary pulmonary metastasis from a phyllodes tumor of the breast appearing 16 years after initial surgery. The patient was a 56-year-old woman who had undergone surgical extirpation of a left breast tumor diagnosed as phyllodes tumor (borderline malignancy) in 1998, and a right breast tumor diagnosed as fibromatosis in 2000. Sixteen years after the initial operation, she consulted our hospital because of a chest X-ray abnormality detected at a screening examination. Chest computed tomography revealed a well defined nodular shadow in the left upper lobe of the lung. Surgery was done since primary lung cancer was suspected. However, pathological diagnosis was a pulmonary metastasis from the phyllodes tumor of the left breast. Right breast tumor was also diagnosed as a metastasis from the left breast tumor by histopathological re-evaluation.

    Wu, S D; Han, J Y


    Objective: To discuss the preliminary experience of single incision laparoscopic colorectal surgery. Methods: The clinical data and surgical outcomes of 104 selected patients who underwent single incision laparoscopic colorectal surgery in the 2 nd Department of General Surgery, Shengjing Hospital of China Medical University from January 2010 to September 2015 were retrospectively analyzed. There were 62 male and 42 female patients, aging from 21 to 87 years with a mean of (61±12) years. Eighty-five patients were diagnosed with malignancy while the rest 19 cases were benign diseases. All the procedures were performed by the same surgeon using the rigid laparoscopic instruments. Surgical and oncological outcomes were analyzed in 4 kinds of procedures which are over 5 cases respectively, including low anterior resection, abdominoperineal resection, radical right colon resection and radical sigmoidectomy. Results: Single incision laparoscopic colorectal surgery was performed in 104 selected patients and was successfully managed in 99 cases with a total conversion rate of 4.8%. Radical procedures for malignancy in cases with the number of patients more than 5 were performed for 74 cases. For low anterior resection, 35 cases with an average surgical time of (191±57) minutes, average estimated blood loss of (117±72) ml and average number of harvested lymph nodes of 14.6±1.1. For abdominoperineal resection, 9 cases with an average surgical time of (226±54) minutes, average estimated blood loss of (194±95) ml and average number of harvested lymph nodes of 14.1±1.5. For radical right colon resection, 16 cases with an average surgical time of (222±62) minutes, average estimated blood loss of (142±68) ml and average number of harvested lymph nodes of 15.4±2.4. For radical sigmoidectomy, 14 cases with an average surgical time of (159±32) minutes, average estimated blood loss of (94±33) ml and average number of harvested lymph nodes of 13.9±1.5. The overall

  19. Early clinical outcomes after small incision lenticule extraction surgery (SMILE). (United States)

    Recchioni, Alberto; Hartwig, Andreas; Dermott, Jay; Vaswani, Sundeep; Bhatt, Jay; Morris, Robert; O'Donnell, Clare


    Dry eye is known to impact on clinical outcomes after laser vision correction and the use of a newer 'all femtosecond laser' surgical approach may be associated with less impact on the ocular surface post-operatively. The purpose of this study was to evaluate the early clinical outcomes and tear instability after the first small incision lenticule extraction (SMILE) cases undertaken by three surgeons at a single site in the UK. Retrospective audit. Seventy-one eyes of 37 patients underwent SMILE surgery using the Zeiss VisuMax laser system (Carl Zeiss Meditec, Germany). Uncorrected and corrected distance visual acuity, spherical equivalent refraction, fluorescein enhanced tear break up time, simulated keratometry and complications were evaluated pre- and post-operatively where applicable. The study population consisted of 21 males and 16 females. The mean±standard deviation age was 33±8years. The results showed that 100% of eyes achieved 20/40 or better and 88% achieved 20/20 or better uncorrected distance visual acuity. The spherical equivalent refraction after surgery was within ±0.50D in 82% of eyes at three months. There was no significant difference in tear break up time from pre-operative levels at three months. Complications were infrequent. This early data from surgeons' first SMILE procedures suggest SMILE provides good outcomes in terms of refractive predictability and visual acuity with minimal impact on the tear film. Longitudinal research will further improve our understanding of the longer-term impact of SMILE on clinical outcomes, ocular surface metrics and patient reported outcomes. Copyright © 2017.

  20. Open-heart Surgery Complications Following Programmed Education and Nurses' Clinical Competence

    Directory of Open Access Journals (Sweden)

    Mahnaz Rakhshan


    Full Text Available Heart surgery can lead to certain complications that, if not diagnosed and treated on time, can be fatal. In view of the fact that nurses' clinical competence affects the quality of clinical judgment, the present study aimed to explore the effect of programmed education and nurses' clinical competence on complications following open-heart surgeries. The results of the present study showed that a closer attention to regular and programmed education and informing of open-heart surgery patients, especially before surgery and at the time of discharge, along with the clinical competence of nurses in ICUs, can reduce the incidence of post-surgery complications. Since the nurses' clinical competence greatly affects their clinical judgments and quality of care, paying greater attention to the nurses' education through systematic programs and increasing the clinical competence can lead to fewer post-heart-surgery complications; this, in turn, reduces the length of stay and the ensuing costs.

  2. [Clinical effects of simple hallux valgus surgery for transfer metatarsalgia]. (United States)

    Wang, X J; Bao, B X; Wei, F Y; Zhang, J Z


    Objective: To analyze the clinical effects of simple hallux valgus surgery for transfer metatarsalgia. Methods: From September 2011 to November, a total of 21 patients(30 feets)with transfer metatarsalgia of hallux valgus and underwent the simple hallux valgus surgery without lateral metatarsal shortening osteotomy In Department of Orthopedics, Beijing Tongren Hospital, Capital Medical University, were enrolled in the study.The hallux valgus angle (HVA), intermetatarsal angle (IMA) , AOFAS scale and analogue score (VAS) were measured pre-operation and a half year, one year, two years after operation.The data were measured repeatedly and analyzed with analysis of variance. Results: The mean preoperative HVA changed [(39.6±9.7), (14.2±7.9), (14.8±7.9), (13.2±6.5)°] at 6 months, 1 year and 2 years follow-up; the mean IMA decreased [(13.8±4.0), (4.5±4.3), (5.8±3.9), (5.4±4.9)°] at 6 months, 1 year and 2 years follow-up(all P surgeries. The mean AOFAS for hallux , AOFAS for lesser toes and VAS were improved from 58.96 to 95.42, from 84.38 to 92.04 and from 7.5 to 1.3, respectively. All the results are statistically significant( P <0.001). Conclusion: These results suggest that a simple osteotomy of the first metatarsal provides excellent outcomes with a low rate of complications when compared with the combining lateral metatarsal shortening osteotomy.

  3. [Incidence and clinical impact of seizures after surgery for chronic subdural haematoma]. (United States)

    Battaglia, F; Lubrano, V; Ribeiro-Filho, T; Pradel, V; Roche, P-H


    Seizures can occur in patients who have surgery for a chronic subdural hematoma. However, the incidence of seizures and their impact on the clinical course of patients in the perioperative period is not well known. In this retrospective study, we reviewed 161 cases of patients treated for chronic subdural hematoma in our institution. The surgical procedures consisted in trephine craniotomy in 156 cases, burr-hole craniotomy in three cases, and bone flap craniotomy in two cases. All the patients had systematic antiepileptic drug prophylaxis. In our patients' population, the incidence of seizures was 10.6% before surgery and 14.9% after surgery. Low initial score on the Glasgow Coma Scale (Pcognitive impairment (P=0.005) were associated with a higher rate of postoperative seizures. In our study, the mortality rate was 14.9%. Low initial score on the Glasgow Coma Scale (P=0.068) and postoperative seizures (P=0.002) were associated with a higher mortality rate. We have shown that patients suffering from seizures may have worse outcome. The benefit of a systematic perioperative prophylaxis using antiepileptic drugs has to be evaluated.

  4. Children's surgery: a national survey of consultant clinical practice. (United States)

    Mason, David G; Shotton, Hannah; Wilkinson, Kathleen A; Gough, Michael J; Alleway, Robert; Freeth, Heather; Mason, Marisa


    To survey clinical practice and opinions of consultant surgeons and anaesthetists caring for children to inform the needs for training, commissioning and management of children's surgery in the UK. The National Confidential Enquiry into Patient Outcome and Death (NCEPOD) hosted an online survey to gather data on current clinical practice of UK consultant surgeons and anaesthetists caring for children. The questionnaire was circulated to all hospitals and to Anaesthetic and Surgical Royal Colleges, and relevant specialist societies covering the UK and the Channel Islands and was mainly completed by consultants in District General Hospitals. 555 surgeons and 1561 anaesthetists completed the questionnaire. 32.6% of surgeons and 43.5% of anaesthetists considered that there were deficiencies in their hospital's facilities that potentially compromised delivery of a safe children's surgical service. Almost 10% of all consultants considered that their postgraduate training was insufficient for current paediatric practice and 20% felt that recent Continued Professional Development failed to maintain paediatric expertise. 45.4% of surgeons and 39.2% of anaesthetists considered that the current specialty curriculum should have a larger paediatric component. Consultants in non-specialist paediatric centres were prepared to care for younger children admitted for surgery as emergencies than those admitted electively. Many of the surgeons and anaesthetists had consultant surgeons and anaesthetists providing a competent surgical service for children. Postgraduate curricula must meet the needs of trainees who will be expected to include children in their caseload as consultants. Trusts must ensure appropriate support for consultants to maintain paediatric skills and provide the necessary facilities for a high-quality local surgical service.

  6. Ketamine in adult cardiac surgery and the cardiac surgery Intensive Care Unit: An evidence-based clinical review

    Directory of Open Access Journals (Sweden)

    Michael Mazzeffi


    Full Text Available Ketamine is a unique anesthetic drug that provides analgesia, hypnosis, and amnesia with minimal respiratory and cardiovascular depression. Because of its sympathomimetic properties it would seem to be an excellent choice for patients with depressed ventricular function in cardiac surgery. However, its use has not gained widespread acceptance in adult cardiac surgery patients, perhaps due to its perceived negative psychotropic effects. Despite this limitation, it is receiving renewed interest in the United States as a sedative and analgesic drug for critically ill-patients. In this manuscript, the authors provide an evidence-based clinical review of ketamine use in cardiac surgery patients for intensive care physicians, cardio-thoracic anesthesiologists, and cardio-thoracic surgeons. All MEDLINE indexed clinical trials performed during the last 20 years in adult cardiac surgery patients were included in the review.

    Kalarchian, Melissa A.; Marcus, Marsha D.; Courcoulas, Anita P.; Cheng, Yu; Levine, Michele D.


    Background Studies of the impact of pre-surgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed. Objective To evaluate whether a pre-surgery behavioral lifestyle intervention improves weight loss through 24-months post-surgery. Setting Bariatric Center of Excellence at a large, urban medical center. Methods Candidates for bariatric surgery were randomized to a 6-month behavioral lifestyle intervention or to 6 months of usual pre-surgical care. The lifestyle intervention consisted of 8 weekly face-to-face sessions followed by 16 weeks of face-to-face and telephone sessions prior to surgery; the intervention also included 3 monthly telephone contacts after surgery. Assessments were conducted at 6-, 12- and 24-months post-surgery. Results Participants who underwent surgery (n = 143) were 90.2% female and 86.7% White. Average age was 44.9 years, and average BMI was 47.5 kg/m2 at study enrollment. At follow-up, 131 (91.6%), 126 (88.1%), 117 (81.8%) patients participated in the 6-, 12- and 24 month assessments, respectively. Percent weight loss from study enrollment to 6- and 12-months post-surgery was comparable for both groups, but at 24-months post-surgery, the lifestyle group had significantly smaller percent weight loss than the usual care group (26.5% vs. 29.5%, respectively, p = 0.02). Conclusions Pre-surgery lifestyle intervention did not improve weight loss at 24 months post-surgery. Findings raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients. PMID:26410538

    Translation of basic research results into routine patient care is delayed in parts by lack of institutionalization in clinical research. In this article the research structure and organization of our Department of Cardiac, Thoracic, Transplantation and Vascular Surgery are described.Basic research, separately directed, is accomplished in the Leibniz Research Laboratories for Biotechnology and Artificial Organs (LEBAO) and within the scope of the Excellence cluster "REBIRTH--from Regenerative Biology to Reconstructive Therapy".Clinical research is directed by heads of the subdepartments of our institution (valve and coronary surgery, aortic surgery, surgical electrophysiology, vascular surgery, thoracic surgery, cardiac assist systems, thoracic transplantation, intensive care and pediatric heart surgery).A separate subdepartment for clinical research is responsible for study coordination and accompanies clinical studies from study design and patient screening to publication. This subdepartment also serves as a constant contact to sponsors and superordinated research organizations within the Hannover Medical School.

  9. An initial experience with a digital drainage system during the postoperative period of pediatric thoracic surgery. (United States)

    Costa, Altair da Silva; Bachichi, Thiago; Holanda, Caio; Rizzo, Luiz Augusto Lucas Martins De


    To report an initial experience with a digital drainage system during the postoperative period of pediatric thoracic surgery. This was a prospective observational study involving consecutive patients, ≤ 14 years of age, treated at a pediatric thoracic surgery outpatient clinic, for whom pulmonary resection (lobectomy or segmentectomy via muscle-sparing thoracotomy) was indicated. The parameters evaluated were air leak (as quantified with the digital system), biosafety, duration of drainage, length of hospital stay, and complications. The digital system was used in 11 children (mean age, 5.9 ± 3.3 years). The mean length of hospital stay was 4.9 ± 2.6 days, the mean duration of drainage was 2.5 ± 0.7 days, and the mean drainage volume was 270.4 ± 166.7 mL. The mean maximum air leak flow was 92.78 ± 95.83 mL/min (range, 18-338 mL/min). Two patients developed postoperative complications (atelectasis and pneumonia, respectively). The use of this digital system facilitated the decision-making process during the postoperative period, reducing the risk of errors in the interpretation and management of air leaks. Relatar a experiência inicial com um sistema de drenagem digital no pós-operatório de cirurgia torácica pediátrica. Estudo observacional e prospectivo envolvendo pacientes consecutivos do ambulatório de cirurgia torácica pediátrica da instituição, com idade até 14 anos, e com indicação de ressecção pulmonar (lobectomia e/ou segmentectomia através de toracotomia poupadora muscular). Os parâmetros avaliados foram perda aérea (quantificada com o sistema digital), biossegurança, tempo de drenagem, tempo de internação e complicações. O sistema digital foi utilizado em 11 crianças, com média de idade de 5,9 ± 3,3 anos. A média do tempo de internação foi de 4,9 ± 2,6 dias, a de tempo de drenagem foi de 2,5 ± 0,7 dias, e a de volume de drenagem foi de 270,4 ± 166,7 ml. A média da perda aérea máxima foi de 92,78 ± 95,83 ml

  10. Initial experience of a novel ergonomic surgical chair for laparoscopic pelvic surgery

    Directory of Open Access Journals (Sweden)

    Full Text Available INTRODUCTION: We present the initial experience of a novel surgical chair for laparoscopic pelvic surgery, the ETHOS TM (Bridge City Surgical, Portland, OR. MATERIALS AND METHODS: The ETHOS chair has an adjustable saddle height that ranges from 0.89 to 1.22 m high, an overall width of 0.89 m, and a depth of 0.97 m. The open straddle is 0.53 m and fits most OR tables. We performed 7 pelvic laparoscopy cases with the 1st generation ETHOS TM platform including 2 laparoscopic ureteral reimplantations, 5 laparoscopic pelvic lymphadenectomies for staging prostate cancer in which one case involved a laparoscopic radical retropubic prostatectomy, performed by 2 different surgeons. RESULTS: All 7 pelvic laparoscopic procedures were successful with the ETHOS TM chair. No conversion to open surgery was necessary. Survey done by surgeons after the procedures revealed minimal stress on back or upper extremities by the surgeons from these operations even when surgery was longer than 120 minutes. Conversely, the surgical assistants still had issues with their positions since they were on either sides of the patient stressing their positions during the procedure. CONCLUSION:The ETHOS chair system allows the surgeon to operate seated in comfortable position with ergonomic chest, arms, and back supports. These supports minimize surgeon fatigue and discomfort during pelvic laparoscopic procedures even when these procedures are longer than 120 minutes without consequence to the patient safety or detrimental effects to the surgical team.

  11. Surgery as a Double-Edged Sword: A Clinically Feasible Approach to Overcome the Metastasis-Promoting Effects of Surgery by Blunting Stress and Prostaglandin Responses

    Surgery remains an essential therapeutic approach for most solid malignancies, including breast cancer. However, surgery also constitutes a risk factor for promotion of pre-existing micrometastases and the initiation of new metastases through several mechanisms, including the release of prostaglandins and stress hormones (e.g., catecholamines and glucocorticoids). However, the perioperative period also presents an opportunity for cell mediated immunity (CMI) and other mechanisms to eradicate or control minimal residual disease, provided that the deleterious effects of surgery are minimized. Here, we discuss the key role of endogenous stress hormones and prostaglandins in promoting the metastatic process through their direct impact on malignant cells, and through their deleterious impact on anti-cancer CMI. We further discuss the effects of anesthetic techniques, the extent of surgery, pain alleviation, and timing within the menstrual cycle with respect to their impact on tumor recurrence and physiological stress responses. Last, we suggest an attractive perioperative drug regimen, based on a combination of a cyclooxygenase (COX)-2 inhibitor and a β-adrenergic blocker, which we found effective in attenuating immune suppression and the metastasis-promoting effects of surgery in several tumor models. This regimen is clinically applicable, and could potentially promote disease free survival in patients operated for breast and other types of cancer.

    Lin, Ning; Qiu, Jin-hua; Wu, Yu-lian; Lin, Zheng; Cao, Lian-fang; Lin, Xiao-dan; Lu, Li-qin; Jiang, Ping; Zhu, Su-yun


    To study 3 different strategies of urine drainage following hypospadias urethroplasty, the clinical nursing in their application, and their effects. We retrospectively analyzed the clinical data of 595 cases of hypospadias treated by urethroplasty. After surgery, 133 of the patients underwent urine drainage by suprapubic cystostomy (group A), 202 by urethral stent- tube indwelling (group B), and 260 by early initiative micturition with the urethral stent-tube (group C). All the patients received routine postoperative nursing care required for hypospadias repair. Operations were successfully completed in all the cases. Group C showed a remarkably shorter hospital stay and lower incidence rates of urinary fistula and urethral stricture than groups A and B (Ppostoperative complications, decrease difficulties and workload of nursing care, and shorten the hospital stay of the patient.

    Gebhart, Martina


    The number of patients undergoing bariatric surgery because of morbid obesity is increasing rapidly. Therefore, it is an important issue to be aware of outcome and complications after bariatric surgery. This mini-review presents a compilation of important gastrointestinal symptoms, as pain, diarrhea and dumping, and includes treatment options. It characterizes possible micronutrient deficiencies, gives instructions concerning the adaptation of drugs and illustrates possible adverse outcomes, such as excessive weight loss, insufficient weight loss and weight gain after bariatric surgery.

  15. Surgical aspects of Operation Bali Assist: initial wound surgery on the tarmac and in flight. (United States)

    Read, David; Ashford, Bruce


    The explosion of three bombs on 12 October 2002 in Kuta, Bali resulted in mass casualties akin to those seen in war. The aim of the present report is to describe the sequence of events of Operation Bali Assist including triage, resuscitation and initial wound surgery in Bali at Sanglah Hospital in the aeromedical staging facility (ASF), Denpasar airport and the evacuation to Darwin. A descriptive report is provided of the event and includes; resuscitation, anaesthesia, initial burns surgery management including escharotomy and fasciotomy, head injury management and importance of supplies and medical records with a description of the evacuation to Darwin. Operation Bali Assist involved five C130 Hercules aircraft and aeromedical evacuation medical and nursing teams managing 66 casualties in the Denpasar area and their evacuation to Royal Darwin Hospital with ketamine the most useful anaesthetic agent and cling film the most useful burns dressing. Twelve procedures were performed at the ASF including seven escharotomies, three fasciotomies and two closed reductions. One escharotomy was performed in flight. The important lessons learnt from the exercise is the inclusion of a surgeon in the aeromedical evacuation team, the importance of debridement and delayed primary closure, the usefulness of cling film as a burns dressing and the importance of continuous assessment. Future disaster planning exercises need to consider a patient age mix that might be expected in a shopping mall, rather than the young adult encountered in Bali, a more familiar age mix for Australian Defence Force medical staff.

  16. Quality improvement initiative: Preventative Surgical Site Infection Protocol in Vascular Surgery. (United States)

    Parizh, David; Ascher, Enrico; Raza Rizvi, Syed Ali; Hingorani, Anil; Amaturo, Michael; Johnson, Eric


    Objective A quality improvement initiative was employed to decrease single institution surgical site infection rate in open lower extremity revascularization procedures. In an attempt to lower patient morbidity, we developed and implemented the Preventative Surgical Site Infection Protocol in Vascular Surgery. Surgical site infections lead to prolonged hospital stays, adjunctive procedure, and additive costs. We employed targeted interventions to address the common risk factors that predispose patients to post-operative complications. Methods Retrospective review was performed between 2012 and 2016 for all surgical site infections after revascularization procedures of the lower extremity. A quality improvement protocol was initiated in January 2015. Primary outcome was the assessment of surgical site infection rate reduction in the pre-protocol vs. post-protocol era. Secondary outcomes evaluated patient demographics, closure method, perioperative antibiotic coverage, and management outcomes. Results Implementation of the protocol decreased the surgical site infection rate from 6.4% to 1.6% p = 0.0137). Patient demographics and comorbidities were assessed and failed to demonstrate a statistically significant difference among the infection and no-infection groups. Wound closure with monocryl suture vs. staple proved to be associated with decreased surgical site infection rate ( p site infections in the vascular surgery population are effective and necessary. Our data suggest that there may be benefit in the incorporation of MRSA and Gram-negative coverage as part of the Surgical Care Improvement Project perioperative guidelines.

    Although the technical developments of radiotherapy have been remarkable, there are currently few reports on the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as initial treatment in this three-dimensional conformal radiotherapy era. Thus, we retrospectively evaluated the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as the initial treatment. Thirty-two patients who underwent radiotherapy were enrolled in this study. The dose per fraction was 2.0–3.5 Gy. Because the treatment schedule was variable, the biological effective dose (BED) was calculated. Local control (LC) and overall survival (OS) rates from the completion of radiotherapy were calculated. The 1-, 2-, 3-, 4-, and 5-year LC rates were 51.5%, 24.5%, 19.6%, 19.6%, and 13.1%, respectively. LC rates were significantly higher for the high BED group (≥75 Gy10) than for the lower BED group (<75 Gy10). All patients who reported pain achieved pain relief. The duration of pain relief was significantly higher for the high BED group than for the lower BED group. The 1-, 2-, 3-, 4-, and 5-year OS rates were 82.6%, 56.5%, 45.2%, 38.7%, and 23.2%, respectively. There was a trend toward higher OS rates in with higher BED group compared to lower BED group. For patients with unresectable locally recurrent rectal cancer treated with surgery alone, radiotherapy is effective treatment. The prescribed BED should be more than 75 Gy10, if the dose to the organ at risk is within acceptable levels.

  18. Depression in young people: initial presentation and clinical course. (United States)

    McCauley, E; Myers, K; Mitchell, J; Calderon, R; Schloredt, K; Treder, R


    This project was designed to provide prospective data on the clinical presentation and longitudinal course of depression in children and adolescents. Children and their parent(s) completed a structured diagnostic interview (Schedule for Affective Disorders and Schizophrenia for School Age Children) at intake, and then yearly for 3 years. Collateral data were collected on school, social, and family functioning. Mean length of initial depressive episode was 35.6 weeks, SD of 26 weeks. Of the 65 depressed youths who completed the 3-year follow-up, 35 (54%) disclosed another episode of depression. Demographic, family-environment, and diagnostic variables were explored as predictors of characteristics of initial episode, recurrence of depression, and psychosocial competence at follow-up. Female gender and presence of a coexisting anxiety disorder were significantly related to severity of initial depression. Family environment was the only predictor significantly related to overall psychosocial competence over 3 years. The findings confirm depression in youth as a valid clinical phenomenon, with substantial risk of recurrence. Increased levels of stress in the family environment were associated with poorer overall outcomes.

    Kalarchian, Melissa A; Marcus, Marsha D; Courcoulas, Anita P; Cheng, Yu; Levine, Michele D


    Studies on the impact of presurgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed. To evaluate whether a presurgery behavioral lifestyle intervention improves weight loss through a 24-month postsurgery period. Bariatric Center of Excellence at a large, urban medical center. Candidates for bariatric surgery were randomized to a 6-month behavioral lifestyle intervention or to 6 months of usual presurgical care. The lifestyle intervention consisted of 8 weekly face-to-face sessions, followed by 16 weeks of face-to-face and telephone sessions before surgery; the intervention also included 3 monthly telephone contacts after surgery. Assessments were conducted 6, 12, and 24 months after surgery. Participants who underwent surgery (n = 143) were 90.2% female and 86.7% White. Average age was 44.9 years, and average body mass index was 47.5 kg/m(2) at study enrollment. At follow-up, 131 (91.6%), 126 (88.1%), 117 (81.8%) patients participated in the 6-, 12-, and 24-month assessments, respectively. Percent weight loss from study enrollment to 6 and 12 months after surgery was comparable for both groups, but at 24 months after surgery, the lifestyle group had significantly smaller percent weight loss compared with the usual care group (26.5% versus 29.5%, respectively, P = .02). Presurgery lifestyle intervention did not improve weight loss at 24 months after surgery. The findings from this study raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients.

  20. Process, cost, and clinical quality: the initial oral contraceptive visit. (United States)

    McMullen, Michael J; Woolford, Samuel W; Moore, Charles L; Berger, Barry M


    To demonstrate how the analysis of clinical process, cost, and outcomes can identify healthcare improvements that reduce cost without sacrificing quality, using the example of the initial visit associated with oral contraceptive pill use. Cross-sectional study using data collected by HealthMETRICS between 1996 and 2009. Using data collected from 106 sites in 24 states, the unintended pregnancy (UIP) rate, effectiveness of patient education, and unit visit cost were calculated. Staff type providing education and placement of education were recorded. Two-way analysis of variance models were created and tested for significance to identify differences between groups. Sites using nonclinical staff to provide education outside the exam were associated with lower cost, higher education scores, and a UIP rate no different from that of sites using clinical staff. Sites also providing patient education during the physical examination were associated with higher cost, lower education scores, and a UIP rate no lower than that of sites providing education outside of the exam. Through analyzing process, cost, and quality, lower-cost processes that did not reduce clinical quality were identified. This methodology is applicable to other clinical services for identifying low-cost processes that do not result in lower clinical quality. By using nonclinical staff educators to provide education outside of the physical examination, sites could save an average of 32% of the total cost of the visit.

  1. Secondary cytoreductive surgery including rectosigmoid colectomy for recurrent ovarian cancer: operative technique and clinical outcome. (United States)

    Bristow, Robert E; Peiretti, Michele; Gerardi, Melissa; Zanagnolo, Vanna; Ueda, Stefanie; Diaz-Montes, Teresa; Giuntoli, Robert L; Maggioni, Angelo


    To describe the operative technique and associated clinical outcomes of patients undergoing rectosigmoid colectomy as a component of secondary cytoreductive surgery for recurrent ovarian cancer. Consecutive patients undergoing rectosigmoid colectomy for recurrent epithelial ovarian cancer between 1/01 and 12/07 were retrospectively identified and clinical data abstracted from the medical record. The surgical technique, associated morbidity, and clinical outcomes are described. Fifty-six patients were identified. The median age at secondary surgery was 56 years; 78.6% had advanced-stage disease at initial diagnosis; 69.6% had grade 3 tumors; 73.2% had serous histology. Complete cytoreduction to no gross residual disease was achieved in 85.7% of cases. Concurrent distal ureterectomy/partial cystectomy was required in 8 cases (14.3%). The median number of regional cytoreductive procedures outside the pelvis was 1 (range=0-4). A stapled coloproctostomy was performed in 98.2% of patients; a protective colostomy/ileostomy was constructed in 7 cases (12.5%), and one patient (1.8%) underwent end colostomy. The median EBL was 500 cm(3) and the median operative time was 225 min. Blood transfusion was administered to 48.2% of patients. Post-operative morbidity occurred in 23.2% of patients, with a bowel fistula rate of 5.4% and a mortality rate of 1.8%. The median LOS was 9 days. Post-operative platinum-based chemotherapy was administered in 73.2% of patients. The median overall survival time from secondary surgery was 38.4 months. Rectosigmoid colectomy can contribute significantly to a maximal cytoreductive surgical effort for recurrent ovarian cancer. Despite technical differences, including a frequent requirement for resection of the distal urinary tract, morbidity is comparable to rectosigmoid colectomy performed for primary cytoreduction and the associated survival outcome appears favorable.

  2. Rectal prolapse as initial clinical manifestation of colon cancer. (United States)

    Chen, C-W; Hsiao, C-W; Wu, C-C; Jao, S-W


    Rectal prolapse as the initial clinical manifestation of colorectal cancer is uncommon. We describe the case of a 75-year-old woman who was diagnosed as having adenocarcinoma of the sigmoid colon after presenting with complete rectal prolapse. The tumor caused rectosigmoid intussusception and then it prolapsed out through the anus. She underwent rectosigmoidectomy and rectopexy. The postoperative course was uneventful. The relationship between colorectal cancer and rectal prolapse has not been clearly established. This case report describes an unusual presentation of colorectal cancer. It suggests that rectal prolapse can present as the initial symptom of colorectal cancer and may also be a presenting feature of the occult intra-abdominal pathology. The importance of adequate investigation such as colonoscopy should be emphasized in patients who develop a new onset of rectal prolapse.

  4. Endoscopic endonasal transsphenoidal surgery using the iArmS operation support robot: initial experience in 43 patients. (United States)

    Ogiwara, Toshihiro; Goto, Tetsuya; Nagm, Alhusain; Hongo, Kazuhiro


    Objective The intelligent arm-support system, iArmS, which follows the surgeon's arm and automatically fixes it at an adequate position, was developed as an operation support robot. iArmS was designed to support the surgeon's forearm to prevent hand trembling and to alleviate fatigue during surgery with a microscope. In this study, the authors report on application of this robotic device to endoscopic endonasal transsphenoidal surgery (ETSS) and evaluate their initial experiences. Methods The study population consisted of 43 patients: 29 with pituitary adenoma, 3 with meningioma, 3 with Rathke's cleft cyst, 2 with craniopharyngioma, 2 with chordoma, and 4 with other conditions. All patients underwent surgery via the endonasal transsphenoidal approach using a rigid endoscope. During the nasal and sphenoid phases, iArmS was used to support the surgeon's nondominant arm, which held the endoscope. The details of the iArmS and clinical results were collected. Results iArmS followed the surgeon's arm movement automatically. It reduced the surgeon's fatigue and stabilized the surgeon's hand during ETSS. Shaking of the video image decreased due to the steadying of the surgeon's scope-holding hand with iArmS. There were no complications related to use of the device. Conclusions The intelligent armrest, iArmS, seems to be safe and effective during ETSS. iArmS is helpful for improving the precision and safety not only for microscopic neurosurgery, but also for ETSS. Ongoing advances in robotics ensure the continued evolution of neurosurgery.

  5. Association of time-to-surgery with outcomes in clinical stage I-II pancreatic adenocarcinoma treated with upfront surgery. (United States)

    Swords, Douglas S; Zhang, Chong; Presson, Angela P; Firpo, Matthew A; Mulvihill, Sean J; Scaife, Courtney L


    Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

  6. Clinical Practice Guidelines Decrease Unnecessary Echocardiograms Before Hip Fracture Surgery. (United States)

    Adair, Chris; Swart, Eric; Seymour, Rachel; Patt, Joshua; Karunakar, Madhav A


    Preoperative assessment of geriatric patients with a hip fracture may include transthoracic echocardiography (TTE), which increases resource utilization and cost and may delay surgery. The purpose of this study was to evaluate preoperative TTE utilization at a single institution in order to determine (1) how often TTE is ordered in accordance with clinical practice guidelines (CPGs), (2) how frequently TTE reveals cardiac disease that may alter medical or anesthesia management, and (3) whether following CPGs reduces unnecessary TTE utilization without potentially missing important disease. A retrospective review of data on 100 geriatric patients with a hip fracture who had undergone preoperative TTE was performed. Charts were reviewed to evaluate if TTE had been obtained in accordance with the published CPGs from the American College of Cardiology/American Heart Association (ACC/AHA). TTE reports were reviewed for the presence of disease that was important enough to cause modifications in anesthesia or perioperative management, including new left ventricular systolic or diastolic dysfunction, moderate or severe valvular disease, and pulmonary hypertension. Finally, the sensitivity and specificity of accordance with the ACC/AHA CPGs for predicting which patients would have TTE that identified important disease were calculated. The TTE was ordered in accordance with the published ACC/AHA CPGs for 66% of the patients. TTE revealed disease with the potential to modify anesthesia or medical management in 14% of the patients-for all of whom the TTE had been indicated according to ACC/AHA guidelines (i.e., the guidelines were 100% sensitive). In this study population, following the ACC/AHA guidelines could have prevented the performance of TTE in 34% of the patients without missing any disease (40% specificity). Preoperative TTE for patients with a hip fracture is frequently obtained outside the recommendations of established CPGs. Utilization of CPGs such as the ACC

  8. Implementing a robotics curriculum at an academic general surgery training program: our initial experience. (United States)

    Winder, Joshua S; Juza, Ryan M; Sasaki, Jennifer; Rogers, Ann M; Pauli, Eric M; Haluck, Randy S; Estes, Stephanie J; Lyn-Sue, Jerome R


    The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.

  9. "Minimally invasive video-assisted thyroidectomy. Initial experience in a general surgery department". (United States)

    Dobrinja, Chiara; Trevisan, Giuliano; Liguori, Gennaro


    The aim of this study is to analyze our preliminary results from minimally invasive video-assisted thyroidectomy (MIVAT) and demonstrate the feasibility of MIVAT also in non-referral centers. We report our initial experience based on a series of 47 patients selected for MIVAT at General Surgery Department of University of Trieste during a period from May 2005 to February 2007. The eligibility criteria were rigorously observed. Age, goiter volume, major diameter of the dominant nodule, operative times, pathologic findings, postoperative pain, length of hospital stay, cosmetic results, and complications were retrospectively analyzed. Thyroid lobectomy was successfully accomplished in 33 cases, total thyroidectomy in 14. Conversion to standard cervicotomy was required in three patients (6%). Mean operative time of lobectomy was 82.6 min and 118.7 for total thyroidectomy. Postoperative complications included 11 (23.4%) transient hypocalcemias, 2 (4.2%) hematomas, and 2 (4.2%) temporary laryngeal nerve palsies. None-recurrent nerve palsies was observed. The cosmetic result was excellent in most cases. Our experience demonstrates that MIVAT, after adequate training, is feasible and safe, with results comparable to conventional thyroidectomy, also in a General Surgery Department, from a dedicated team, with a sufficient and specific activity volume.

  11. A Case of Phosphoglyceride Crystal Deposition Disease in the Pelvic Soft Tissues Recurring after Initial Surgery

    Directory of Open Access Journals (Sweden)

    Yuki Yamada


    Full Text Available Phosphoglyceride crystal deposition disease (PGDD is a rare disease entity that is characterized by phosphoglyceride crystal deposition that stimulates the formation of masses in soft tissue scars or bones. We report a case of PGDD in the pelvic soft tissues that recurred after initial surgical treatment. A 50-year-old woman was referred to our hospital for the evaluation of pelvic masses that were observed on an abdominal ultrasound. Magnetic resonance imaging (MRI revealed masses in the pelvic region, with the largest being 10 cm in diameter. The masses were diagnosed as ovarian malignant tumors, and an exploratory laparotomy was performed. Operative findings revealed them to be foreign body granulomas, and the patient was diagnosed with PGDD. The patient had a history of cesarean delivery at the age of 24 years. PGDD is extremely rare, but it should be considered in the differential diagnosis of abdominal masses in patients with a history of abdominal surgery.

  12. Acute pancreatitis following scoliosis surgery: description and clinical course in 14 adolescents. (United States)

    El Bouyousfi, Maalik; Leveque, Christine; Miladi, Lotfi; Irtan, Sabine; Hamza, Jamil; Oualha, Mehdi


    Acute pancreatitis is a possible complication after scoliosis surgery. Although some risk factors have been documented in the literature, clinical description of pancreatitis diagnosis and ensuing course still remain very poor. The aim of this study was to describe characteristics of acute pancreatitis after scoliosis surgery. A descriptive, retrospective and single-center study of fourteen adolescents with postoperative acute pancreatitis after spine fusion surgery in scoliosis management between April 2003 and August 2012 was performed. Acute pancreatitis occurred within 9.5 days (4-51) after surgery. Abdominal pain was atypical and was expressed in only half of the children. Ileus, nausea and vomiting were the most frequent signs. None of the acute pancreatitis cases was severe. Acute pancreatitis is an early complication of scoliosis surgery. Clinical signs are atypical and non-severe and can induce misleading forms. Presence of delayed digestive problems should alert the clinician to the risk of pancreatitis in the aftermath of scoliosis surgery.

  13. Clinics of Oblivion: Makeover Culture and Cosmetic Surgery

    Directory of Open Access Journals (Sweden)

    Meredith Jones


    Full Text Available This paper examines cosmetic surgery tourism, arguing that it can be meaningfully analysed as part of makeover culture. It shows that while cosmetic surgery tourism sits at a junction of cosmetic surgery and medical tourism, it also has much in common with contemporary tourism practices. The paper posits cosmetic surgery tourism not only as an economic and globalised phenomenon but also as a set of practices that are experienced, and that take place on the body (see also Cook, 2010; Bell et al. 2011. Chris Rojek’s work on contemporary tourist practices is deployed in order to argue that the cosmetic surgery tourist’s body is itself the ‘site’ to be visited and discovered; it is also the souvenir that is brought home. When body and site are brought together in cosmetic surgery tourism, they form a potent nexus that is unique to a contemporary moment tied up with globalisation and consumption, where both identity and self-transformation are managed through the body.

  14. Hospital-level Variation in Utilization of Surgery for Clinical Stage I-II Pancreatic Adenocarcinoma. (United States)

    Swords, Douglas S; Mulvihill, Sean J; Skarda, David E; Finlayson, Samuel R G; Stoddard, Gregory J; Ott, Mark J; Firpo, Matthew A; Scaife, Courtney L


    To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

  15. Adolescent Idiopathic Scoliosis – case report of a patient with clinical deterioration after surgery

    Directory of Open Access Journals (Sweden)

    Weiss Hans-Rudolf


    Full Text Available Abstract Background Although there is no evidence that the long-term effects of scoliosis surgery are superior to the long-term effects of Adolescent Idiopathic Scoliosis (AIS itself, patients can fear the consequences of not under going this surgery due to incorrect or insufficient information. The main indication for surgical treatment in patients with AIS, is cosmetic. However spinal surgery may, along with other negative side effects, actually cause postoperative clinical deterioration. This complication of surgery has not yet been described in international literature. Case presentation A 15-year old female patient originally presenting with a well-compensated double curve pattern scoliosis. The patient was advised to undergo surgery due to the long-term negative impact of signs and symptoms of scoliosis upon her health. The patient agreed to surgery, which was performed in one of Germanys leading centres for spinal surgery. The thoracolumbar curve was corrected and fused, while the thoracic curve, clearly showing wedged vertebrae, defined as structural scoliosis, remained untreated. This operation left the patient with an unbalanced appearance, with radiological and clinical imbalance to the right. The clinical appearance of the patient though clearly deteriorated post-surgery. Furthermore, the wedged disc space below the fusion area indicates future problems with possible destabilisation accompanied probably by low back pain. Conclusion Scoliosis surgery for patients with AIS is mainly indicated for cosmetic or psychological reasons. Therefore the treatment leading to the best possible clinical appearance and balance has to be chosen. Patients should be informed that surgery will not necessarily improve their health status. Clinical deterioration after surgery may occur, and such information is crucial for an adequate informed consent.

  16. Clinical laboratory reference intervals in pediatrics: the CALIPER initiative. (United States)

    Jung, Benjamin; Adeli, Khosrow


    Reference intervals provided on laboratory reports are essential for appropriate interpretation of test results, and can significantly impact clinical decision-making and the quality of patient care. Careful determination and/or validation of reference intervals by the laboratory for use in the patient population it serves are therefore important to ensure their proper utility. Unfortunately, critical gaps currently exist in accurate and up-to-date pediatric reference intervals for accurate interpretation of laboratory tests performed in children and adolescents. These critical gaps in the available pediatric laboratory reference intervals have the clear potential of contributing to erroneous diagnosis or misdiagnosis of many diseases of childhood and adolescence. Most of the available "normal" ranges for laboratory tests were determined over 2 decades ago on older instruments and technologies, and are no longer relevant considering the current testing technology used by clinical laboratories. It is thus critical and of utmost urgency that a more acceptable and comprehensive database be established. In the present review, we discuss the considerations and challenges faced when generating and validating reference intervals in accordance to the current guidelines published by the Clinical Laboratory Standards Institute (CLSI). We raise particular attention to the present-day deficiencies in available pediatric reference intervals, and highlight the special issues and unique difficulties that are additionally faced when establishing reference intervals in children. Finally, we highlight a recent Canadian initiative, the CALIPER project, whose mandate is to establish and maintain a database of comprehensive and up-to-date pediatric reference intervals to be eventually made available to all clinical laboratories worldwide.

    Raylman, Raymond R; Abraham, Jame; Hazard, Hannah; Koren, Courtney; Filburn, Shannon; Schreiman, Judith S; Kurian, Sobha; Majewski, Stan; Marano, Gary D


    The goal of this initial clinical study was to test a new positron emission/tomography imager and biopsy system (PEM/PET) in a small group of selected subjects to assess its clinical imaging capabilities. Specifically, the main task of this study is to determine whether the new system can successfully be used to produce images of known breast cancer and compare them to those acquired by standard techniques. The PEM/PET system consists of two pairs of rotating radiation detectors located beneath a patient table. The scanner has a spatial resolution of ∼2 mm in all three dimensions. The subjects consisted of five patients diagnosed with locally advanced breast cancer ranging in age from 40 to 55 years old scheduled for pre-treatment, conventional whole body PET imaging with F-18 Fluorodeoxyglucose (FDG). The primary lesions were at least 2 cm in diameter. The images from the PEM/PET system demonstrated that this system is capable of identifying some lesions not visible in standard mammograms. Furthermore, while the relatively large lesions imaged in this study where all visualised by a standard whole body PET/CT scanner, some of the morphology of the tumours (ductal infiltration, for example) was better defined with the PEM/PET system. Significantly, these images were obtained immediately following a standard whole body PET scan. The initial testing of the new PEM/PET system demonstrated that the new system is capable of producing good quality breast-PET images compared standard methods. © 2011 The Authors.

  20. Endogenous and exogenous fluorescence of gastrointestinal tumors: initial clinical observations (United States)

    Borisova, Ekaterina; Plamenova, Lilia; Keremedchiev, Momchil; Vladimirov, Borislav; Avramov, Latchezar


    The limitations of standard endoscopy for detection and evaluation of cancerous changes in gastrointestinal tract (GIT) are significant challenge and initiate development of new diagnostic modalities. Therefore many spectral and optical techniques are applied recently into the clinical practice for obtaining qualitatively and quantitatively new data from gastrointestinal neoplasia with different level of clinical applicability and diagnostic success. One of the most promising approaches is fluorescence detection using naturally existing fluorescent molecules or added fluorescent markers. Deltaaminolevulinic acid / protoporphyrin IX is applied for exogenous fluorescent tumor detection in the upper part of gastrointestinal tract. The 5-ALA is administered per os six hours before measurements at dose 20mg/kg weight. Highpower light-emitting diode at 405 nm is used as a source and the excitation light is passed through the light-guide of standard video-endoscopic system to obtain 2-D visualization. Both kinds of spectra - autofluorescence signals and protoporphyrin IX signal are recorded and stored using a fiber-optic microspectrometer, as in endoscopy instrumental channel a fiber is applied to return information about fluorescence signals. In such way 1-D detection and 2-D visualization of the lesions' fluorescence are received. The results from in vivo detection show significant differentiation between normal and abnormal tissues in 1-D spectroscopic regime, but only moderate discrimination in 2-D imaging.

    Qiao, T; Gao, P Y; Lü, X X; Chen, M Y; Wei, L


    Objective: To evaluate the efficacy of pleural abrasion in treatment of spontaneous pneumothorax with video-assisted thoracic surgery (VATS) for bullae resection. Methods: The clinical data of 158 patients with initial spontaneous pneumothorax who underwent video-assisted thoracic wedge resections with or without pleural abrasion in Henan Provincial People's Hospital from June 2010 to June 2015 were retrospectively analyzed. The patients were assigned to two equal groups according to whether pleural abrasion was applied or not: experimental group (with pleural abrasion) and control group (without pleural abrasion); and there were 79 patients in each group.There were 62 males and 17 females aged 15-60 years (mean age 34 years) in pleural abrasion group. And there were 70 males and 9 females aged 18-60 years (mean age 38 years) in non-pleural abrasion group.After surgery, all patients were evaluated for postoperative pain, chest tube removal time, hospital stay and other complications.Independent samples t test was used to compare the data between groups. Results: Surgeries for 158 patients were performed successfully.No mortality occurred.There was no conversion to thoracotomy.Postoperative pain, operation time, intraoperative blood loss, chest tube removal time, pleural canals flowand average hospital stay in non-pleural abrasion group was significantly lower for 4.4, 19 minutes, 10 ml, 21 hours, 87 ml and 1.4 days respectively when compared with those in pleural abrasion group ( t =32.478, 7.140, 11.093, 7.288, 10.246, 8.070, all P tube removal time and hospital stay in non-pleural abrasion group are all lower than those in pleural abrasion group.And there is no significant difference in the recurrence of pneumothorax between the two groups after VATS bullae resection.

    A pilot study was performed in patients with recurrent back pain after spinal fusion surgery to evaluate the ability of 18 F-NaF PET/CT imaging to correctly identify those requiring surgical intervention and to locate a site amenable to surgical intervention. In this prospective study 22 patients with recurrent back pain after spinal surgery and with equivocal findings on physical examination and CT were enrolled for evaluation with 18 F-NaF PET/CT. All PET/CT images were prospectively reviewed with the primary objective of identifying or ruling out the presence of lesions amenable to surgical intervention. The PET/CT results were then validated during surgical exploration or clinical follow-up of at least 15 months. Abnormal 18 F-NaF foci were found in 16 of the 22 patients, and surgical intervention was recommended. These foci were located at various sites: screws, cages, rods, fixation hardware, and bone grafts. In 6 of the 22 patients no foci requiring surgical intervention were found. Validation of the results by surgery (15 patients) or on clinical follow-up (7 patients) showed that 18 F-NaF PET/CT correctly predicted the presence of an abnormality requiring surgical intervention in 15 of 16 patients and was falsely positive in 1 of 16. In this initial investigation, 18 F-NaF PET/CT imaging showed potential utility for evaluation of recurrent symptoms after spinal fusion surgery by identifying those patients requiring surgical management.

  5. A study of the correlation between patient-reported outcomes and clinical outcomes after cataract surgery in ophthalmic clinics. (United States)

    Mollazadegan, Kaziwe; Lundström, Mats


    To analyse the relationship between patient-reported outcome measures and clinical outcome measures in 42 individual Swedish cataract surgery settings. The study material consisted of follow-up data on cataract extractions collected by the Swedish National Cataract Register in 2008-2011. Patient-reported outcome was measured using the Catquest-9SF questionnaire. A total of 9707 pairs of questionnaires completed before and after a cataract extraction were analysed together with clinical data. The analyses were performed for each clinic. For almost all clinics, a factor related to a poor patient-reported outcome after surgery was a good preoperative self-assessed visual function. For some clinics, up to 50% of the patients stated that they were very satisfied with their vision before surgery. For single clinics, different factors such as large anisometropia (≥3D), capsule complications, biometry prediction error (≥3D) and ocular comorbidity were related to a poor patient-reported outcome. In situations where the clinical outcome was good and the patient-reported outcome was poor, problems with near-vision activities after surgery was the main factor noted. Analysing factors related to a poor patient-reported outcome for each clinic showed large variation. Weak indication for surgery, refractive problems after surgery, surgical complications and a poor chance of visual recovery due to ocular comorbidity were among the reasons for a poor patient-reported outcome. Post-operative care in terms of establishing a good near vision seemed to be another problem for some clinics. © 2014 Acta Ophthalmologica Scandinavica Foundation.

  6. Laparoscopy-assisted ERCP (LA-ERCP) following bariatric gastric bypass surgery: initial experience of a single UK centre. (United States)

    Paranandi, Bharat; Joshi, Deepak; Mohammadi, Borzoueh; Jenkinson, Andrew; Adamo, Marco; Read, Samantha; Johnson, Gavin J; Chapman, Michael H; Pereira, Stephen P; Webster, George J


    Bariatric gastric bypass surgery is being increasingly performed, but endoscopic retrograde cholangiopancreatography (ERCP) in these patients poses a unique challenge because of a lack of per-oral access to the stomach. Small series suggest a higher technical success rate using laparoscopy-assisted ERCP (LA-ERCP) than with an enteroscopic approach via the Roux-en-Y anastomosis. We present initial experience of LA-ERCP in our unit. Retrospective case series of consecutive patients undergoing LA-ERCP in our unit between September 2011 and July 2014. Data was retrieved from electronic, clinical and endoscopy records. Seven LA-ERCPs were performed. All seven patients were female, with median age 44 years (range 36-71). Indications included symptomatic bile duct stones (5/7), benign papillary fibrosis (1/7) and retained biliary stent (1/7). 5/7 (71%) patients had had a prior cholecystectomy. To facilitate LA-ERCP, laparoscopic gastrostomy ports were created in all patients. Duodenal access, biliary cannulation and completion of therapeutic aim were achieved in all patients. 6/7 (86%) patients required endoscopic sphincterotomy. The median duration of procedures was 94 min (range 70-135). Median postoperative length of stay was 2 days (range 1-9). One patient developed mild postprocedural acute pancreatitis, and another patient developed a mild port-site infection. Otherwise, no procedure-related complications were seen. All patients remained well on follow-up (median 14 months (range 1-35) from date of ERCP), with no evidence of further biliary symptoms. Our early experience of LA-ERCP is that it is safe and effective. The technique may require particular consideration, as bariatric surgery is increasingly performed, in a patient group at significant risk of bile duct stones.

  7. Resident Cosmetic Clinic: Practice Patterns, Safety, and Outcomes at an Academic Plastic Surgery Institution. (United States)

    Qureshi, Ali A; Parikh, Rajiv P; Myckatyn, Terence M; Tenenbaum, Marissa M


    Comprehensive aesthetic surgery education is an integral part of plastic surgery residency training. Recently, the ACGME increased minimum requirements for aesthetic procedures in residency. To expand aesthetic education and prepare residents for independent practice, our institution has supported a resident cosmetic clinic for over 25 years. To evaluate the safety of procedures performed through a resident clinic by comparing outcomes to benchmarked national aesthetic surgery outcomes and to provide a model for resident clinics in academic plastic surgery institutions. We identified a consecutive cohort of patients who underwent procedures through our resident cosmetic clinic between 2010 and 2015. Major complications, as defined by CosmetAssure database, were recorded and compared to published aesthetic surgery complication rates from the CosmetAssure database for outcomes benchmarking. Fisher's exact test was used to compare sample proportions. Two hundred and seventy-one new patients were evaluated and 112 patients (41.3%) booked surgery for 175 different aesthetic procedures. There were 55 breast, 19 head and neck, and 101 trunk or extremity aesthetic procedures performed. The median number of preoperative and postoperative visits was 2 and 4 respectively with a mean follow-up time of 35 weeks. There were 3 major complications (2 hematomas and 1 infection requiring IV antibiotics) with an overall complication rate of 1.7% compared to 2.0% for patients in the CosmetAssure database (P = .45). Surgical outcomes for procedures performed through a resident cosmetic clinic are comparable to national outcomes for aesthetic surgery procedures, suggesting this experience can enhance comprehensive aesthetic surgery education without compromising patient safety or quality of care. 4 Risk. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

  8. [Clinical features and weight loss in patients with morbid obesity after bariatric surgery]. (United States)

    Guisado, J A; Vaz, F J; López-Ibor, J J; Rubio, M A


    To analyze the psychological status of morbidly obese patients suffering changes after surgical procedure for weight reduction. We analyze the weight loss in 100 morbidly obese patients (85 female, 15 male) after bariatric surgery (vertical banded gastroplasty). We correlated the percentage of weight loss with the age of these patients, initial weight (body mass index at surgery), quality of life, eating behaviour, psychopathology, personality, and marital status. We have found relation between initial weight and weight loss (heavier patients lose more weight). The percentage of weight loss is associated with the Eating Behaviour (Body Dissatisfaction, Disinhibition), the Quality of Life (Positive Affect), the Psychopathology (Hostility), the Personality Traits (Narcissist), and the Marital Status (Idealistic Distortion). The weight loss in morbidly obese patients after surgery is major in the more obese one. The satisfactory weight loss after surgery improve the eating behaviour, quality of life, psychological and marital status.

  9. The clinical utility of new combination phenylephrine/ketorolac injection in cataract surgery

    Directory of Open Access Journals (Sweden)

    Lawuyi LE


    Full Text Available Lola Elizabeth Lawuyi, Avinash Gurbaxani Moorfields Eye Hospital Dubai, Dubai, UAE Abstract: The maintenance of mydriasis throughout cataract extraction surgery and the control of ocular inflammation are crucial for successful surgical outcomes. The development of miosis during cataract surgery compromises the visualization of the surgical field and working space for surgeons. This may lead to complications that include posterior capsular tear and associated vitreous loss, longer surgical time, and postoperative inflammation. Postoperative inflammation is often uncomfortable and frustrating for patients. It causes pain, redness, and photophobia. This compromises the best-uncorrected vision following surgery and often leads to multiple clinic visits. This article examines the literature published on the current treatments used to manage mydriasis, pain, and inflammation in cataract extraction surgery. Combination phenylephrine/ketorolac injection offers an exciting new class of medication for use in cataract surgery. With the recent approval of Omidria™ (combination of phenylephrine 1% and ketorolac 0.3% by the US Food and Drug Administration (FDA for intraocular use, we review the clinical utility of this new combination injection in cataract surgery. PubMed, MEDLINE, and conference proceedings were searched for the relevant literature using a combination of the following search terms: cataract extraction surgery, pupil dilation (mydriasis, miosis, phenylephrine, ketorolac, Omidria™, intracameral mydriatic. Relevant articles were reviewed and their references checked for further relevant literature. All abstracts were reviewed and full texts retrieved where available.

    Elaine Ferreira Lasaponari


    Full Text Available OBJECTIVE: to assess the efficiency of the Calatonia technique about clinical parameters and pain in the immediate post-surgical phase. METHOD: a randomised study was carried out with 116 patients subjected to a cholecystectomy, by laparoscopy, divided into an experimental group (58 patients and a placebo group (58 patients. The experimental group received the Calatonia technique, while the placebo was only subjected to non-intentional touches. RESULTS: The placebo group and the experimental group were considered homogeneous in terms of the variables: sex, age, physical status classification, duration of surgical procedures and also the time spent recovering in the Post-Anaesthetic Recovery Room. The only variable to show a statistically significant difference was the axillary temperature of the body. In relation to pain, the experimental group showed significant results, and hence it is possible to deduce that the relaxation caused by the Calatonia technique brought some relief of the general situation of pain. CONCLUSION: The application of Calatonia can take up the function of a resource complementary to assistance in the period immediately after surgery.

  11. Clinical supervision for clinical psychology students in Uganda: an initial qualitative exploration. (United States)

    Hall, Jennifer; Kasujja, Rosco; Oakes, Peter


    Burn out in clinical psychologists working in low income countries has been reported. Clinical supervisory structures do not yet exist in Uganda. A way to decrease levels of burn out and increase quality of care for people with mental illness is through clinical supervision. The aim of this study was to explore the initial experiences of supervision for clinical psychology students in Uganda to ascertain whether or not clinical supervision is culturally appropriate, and what aspects of supervision had been helpful and unhelpful. A qualitative design with thematic analysis was utilized. A focus group was held with 12 second year clinical psychology students to ask their experiences of receiving supervision. Data analysis created five themes. Firstly, the negative emotions that resulted from the training processed were discussed, and how supervision helped and did not help the students to manage these. Secondly, the students voiced that supervision helped them to learn through observational experiences, co-therapist roles and parallel processes within the supervisory relationship. Thirdly, supervision had taught the clinical psychology students their role as a clinical psychology student, how to act within the Ugandan mental health system and skills to conduct therapy. Fourthly, suggestions for the future of supervision were given, with the students requesting for it to start earlier in the training, for supervisors who can meet with the students on a regular basis to be selected and for the training the students receive at university to match the skills required on their placements, with a request for more practical techniques rather than theory. The final theme related to left over miscellaneous data, such as the students agreeing with each other. The students stated that supervision was helpful overall, implying that clinical supervision is culturally appropriate for clinical psychology students in Uganda. Suggestions for future supervision were given. In order to

    Wichmann, Matthias W; Eben, Ricarda; Angele, Martin K; Brandenburg, Franzis; Goetz, Alwin E; Jauch, Karl-Walter


    Recent clinical data indicate that fast-track surgery (multimodal rehabilitation) leads to shorter postoperative length of hospital stay, faster recovery of gastrointestinal function as well as reduced morbidity and mortality rates. To date, no study has focused on the effects of fast-track surgery on postoperative immune function. This study was initiated to determine whether fast-track rehabilitation results in improved clinical and immunological outcome of patients undergoing colorectal surgery. Forty patients underwent either conventional or fast-track rehabilitation after colorectal surgery. In addition to clinical parameters (return of gastrointestinal function, food intake, pain score, complication rates and postoperative length of stay), we determined parameters of perioperative immunity by flow cytometry (lymphocyte subgroups) and enzyme-linked immunosorbent assay (interleukin-6). Our findings indicate a better-preserved cell-mediated immune function (T cells, T-helper cells, natural killer cells) after fast-track rehabilitation, whereas the pro-inflammatory response (C-reactive protein, interleukin-6) was unchanged in both study groups. Furthermore, we detected a significantly faster return of gastrointestinal function (first bowel movement P<0.001, food intake P<0.05), significantly reduced pain scores in the postoperative course (P < 0.05) and a significantly shorter length of postoperative stay (P<0.001) in patients undergoing fast-track rehabilitation. Fast-track rehabilitation after colorectal surgery results in better-preserved cell-mediated immunity when compared with conventional postoperative care. Furthermore, patients undergoing fast-track rehabilitation suffer from less pain and have a faster return of gastrointestinal function in the postoperative course. In addition, postoperative length of hospital stay was significantly shorter in fast-track patients.

  13. The psychological and social characteristics of patients referred for NHS cosmetic surgery: quantifying clinical need. (United States)

    Cook, Sharon A; Rosser, Robert; Toone, Helen; James, M Ian; Salmon, Peter


    Elective cosmetic surgery is expanding in the UK in both the public and private sectors. Because resources are constrained, many cosmetic procedures are being excluded within the National Health Service. If guidelines on who can receive such surgery are to be evidence-based, information is needed about the level of dysfunction in patients referred for elective surgery and whether this is related to their degree of physical abnormality. Consecutive patients referred to a regional plastic surgery and burns unit for assessment for elective cosmetic surgery completed standardised measures of physical and psychosocial dysfunction, and indicated their perception of the degree of their abnormality and their preoccupation with it. We distinguished between patients referred for physical reasons or appearance reasons only, and compared levels of physical and psychosocial dysfunction in each with published values for community and clinical samples. Surgeons indicated patients' degree of objective abnormality, and we identified the relationship of dysfunction with perceived and objective abnormality and preoccupation. Whether patients sought surgery for physical or appearance reasons, physical function was normal. Those seeking surgery for appearance reasons only had moderate psychosocial dysfunction, but were not as impaired as clinical groups with psychological problems. Patients seeking the correction of minor skin lesions for purely appearance reasons reported excellent physical and psychosocial function. Level of function was related (negatively) to patients' preoccupation with abnormality rather than to their perceived or objective abnormality. In general, patients referred for elective cosmetic surgery did not present with significant levels of dysfunction. Moreover, levels of functioning were related to preoccupation rather than to objective abnormality. Therefore, for most patients, whether surgical treatment is generally appropriate is questionable.

    Santos, Thiago-de-S; Santos, Jadson-A.; Maia, Marcelo-C; Mendonça, Carla-G


    Objective: Pain reduction has been the subject of continuous research in the field of oral and maxillofacial surgery since postoperative pain with ranging of intensity and duration may affects the patient submitted in an oral surgical procedure. The aim of present study was to compare the analgesic effectiveness between two different anesthetic solutions (articaine and lidocaine) in third molar surgery. Study Design: A prospective, randomized and clinical study with patients submitted to third molar surgery at two distinct times. The visual analogue scale, the McGill Pain Questionnaire and the analgesic consumption record were used to measure the pain after each surgical time. Results: Duration of surgery, latency, the amount of anesthetic used and analgesic consumption showed clinical differences with highlights of articaine, though statistical significance was not observed (Pthird molar.

    Sun, Chenggang; Li, Xin; Sun, Jintang; Zou, Peng; Gao, Shubo; Zhang, Peixun


    To study the clinical treatment features of biliary tract and pancreatic surgery complicated by acute pancreatitis. A retrospective analysis of 21 cases of biliary tract and pancreatic surgery complicated by acute pancreatitis in the Department of General Surgery in our hospital during May 2005 to July 2011 was performed; the clinical treatment features were analyzed in terms of surgical option, onset interval of acute pancreatitis after last surgery, length of stay in hospital and Ranson score. There was no statistic difference between the two groups (A: The onset interval of acute pancreatitis after last surgery acute pancreatitis after last surgery > 0.5 year) in pathogenetic condition and length of stay in hospital. All patients were discharged after treatment, a follow-up of 6-18 months found no recurrence of pancreatitis. There is no relevance between the treatment feature and onset interval of biliary and pancreatic surgery complicated by acute pancreatitis. The disease is still treated meanly with symptomatic and supportive treatment, while the etiological treatment is also particularly important.

    Bariatric surgery is currently the most effective treatment for morbid obesity and its associated metabolic complications. To ensure long-term postoperative success, patients must be prepared to adopt comprehensive lifestyle changes. This review summarizes the current evidence and expert opinions with regard to nutritional care in the perioperative and long-term postoperative periods. A literature search was performed with the use of different lines of searches for narrative reviews. Nutritional recommendations are divided into 3 main sections: 1) presurgery nutritional evaluation and presurgery diet and supplementation; 2) postsurgery diet progression, eating-related behaviors, and nutritional therapy for common gastrointestinal symptoms; and 3) recommendations for lifelong supplementation and advice for nutritional follow-up. We recognize the need for uniform, evidence-based nutritional guidelines for bariatric patients and summarize recommendations with the aim of optimizing long-term success and preventing complications.

    Septic arthritis has to be suspected in children with joint effusion and fever so as to perform joint aspiration, which will confirm the diagnosis by bacteriological methods, and to perform surgical treatment by joint lavage. Since development of current molecular methods, such as real-time PCR, Kingella kingae has become the first microbial agent of osteoarticular infections in young children, whereas Staphylococcus aureus is second. C-reactive protein (CRP) is an aid used to diagnose septic arthritis, but its elevation could be moderate. In a previous study, conducted at our hospital, 10% of children hospitalized for S. aureus or K. kingae septic arthritis had a CRP levelseptic arthritis could be made by other parameters, we analyzed the clinical and biologic features of these patients and compared them to those of children hospitalized for septic arthritis with initial CRP ≥10 mg/L. Among the 89 children with septic arthritis, 10% (n=9) had initial CRPseptic arthritis had no fever, CRP elevation, or fibrinogen elevation. In the CRP-negative group, three of four children with S. aureus arthritis and one of five with K. kingae arthritis had a high CRP level (34, 40, 61, and 13 mg/L, respectively) 3 days after surgery and antibiotic treatment. One child with K. kingae septic arthritis and initial CRParthritis. In the S. aureus arthritis group, none of the children with initial CRP10 mg/L during septic arthritis in children, it could be negative in up to 20% of patients in different studies. However, a mild inflammatory syndrome or even a CRPseptic arthritis. Therefore, a first episode of monoarthritis in children has to be considered as septic arthritis and treatment should not be delayed. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Tanaka, Shinnosuke; Matsuo, Katsuichi; Sasaki, Takamitsu; Nakano, Masahiho; Shimura, Hideo; Yamashita, Yuichi


    The clinical outcomes and advantages of laparoscopic surgery for Crohn's disease have not yet been recognized in general. The aim of this study was to critically assess the clinical outcomes, safety, cosmesis, quality of life (QOL) and feasibility of laparoscopic surgery for primary Crohn's disease. The study subjects consisted of 48 patients who had primary surgical treatment for Crohn's disease, 28 through conventional laparotomy and 20 in whom surgery was laparoscopically assisted. The short-term and long-term outcomes, cosmesis, and postoperative QOL were evaluated in both groups. There were no statistically significant differences in the patient characteristics between the two groups. In the laparoscopic group, non-resected procedures were significantly more frequent (p cosmetic results were very satisfactory in 11 patients (64.7%). There were no severe complications and no increase of the recurrence rate for laparoscopic surgery. Moreover, there was no definite clinical disadvantage and no prolonged operating time in the laparoscopic procedures. Laparoscopic surgery for primary Crohn's disease is safe and feasible in selected patients without severe adhesion, fistula or abscess, and was associated with better cosmesis than conventional open surgery. Therefore, laparoscopic procedures should be considered as the preferred operative approach for a primary bowel resection.

  2. Clinical trials recruitment planning: A proposed framework from the Clinical Trials Transformation Initiative. (United States)

    Huang, Grant D; Bull, Jonca; Johnston McKee, Kelly; Mahon, Elizabeth; Harper, Beth; Roberts, Jamie N


    Patient recruitment is widely recognized as a key determinant of success for clinical trials. Yet a substantial number of trials fail to reach recruitment goals-a situation that has important scientific, financial, ethical, and policy implications. Further, there are important effects on stakeholders who directly contribute to the trial including investigators, sponsors, and study participants. Despite efforts over multiple decades to identify and address barriers, recruitment challenges persist. To advance a more comprehensive approach to trial recruitment, the Clinical Trials Transformation Initiative (CTTI) convened a project team to examine the challenges and to issue actionable, evidence-based recommendations for improving recruitment planning that extend beyond common study-specific strategies. We describe our multi-stakeholder effort to develop a framework that delineates three areas essential to strategic recruitment planning efforts: (1) trial design and protocol development, (2) trial feasibility and site selection, and (3) communication. Our recommendations propose an upstream approach to recruitment planning that has the potential to produce greater impact and reduce downstream barriers. Additionally, we offer tools to help facilitate adoption of the recommendations. We hope that our framework and recommendations will serve as a guide for initial efforts in clinical trial recruitment planning irrespective of disease or intervention focus, provide a common basis for discussions in this area and generate targets for further analysis and continual improvement.

  3. Initial clinical experience with frameless radiosurgery for patients with intracranial metastases

    International Nuclear Information System (INIS)

    Kamath, Reena; Ryken, Timothy C.; Meeks, Sanford L.; Pennington, Edward C.; Ritchie, Justine; Buatti, John M.


    Purpose: To review the initial clinical experience with frameless stereotactic radiosurgery (SRS) for treating intracranial metastatic disease. Methods and Materials: Sixty-four patients received frameless SRS for intracranial metastatic disease. Minimum follow-up was 6 months with none lost to follow-up. Patients had a median of 2 metastases and a maximum of 4. The median number of isocenters was 2 with median arcs of 10 and median dose of 17.5 Gy. Thirteen patients were treated for progressive/recurrent disease after surgical resection or whole brain radiotherapy (WBRT). Fifty-one patients were treated with frameless SRS as an an adjunct to initial treatment. Of the total treated, 17 were treated with SRS alone, 20 were treated with WBRT plus SRS, 16 were treated with surgical resection plus SRS, and the remaining 11 were treated with surgical resection plus WBRT plus SRS. Results: With a median actuarial follow-up period of 8.2 months, ultimate local control was 88%. The median time to progression was 8.1 months. The median overall survival was 8.7 months. Of the 17 patients treated with SRS alone, 86% had ultimate local control with mean overall survival of 7.1 months. Of the 13 patients who received surgical resection plus SRS without WBRT as primary treatment, there was 85% ultimate local control with an overall survival of 10.3 months. Three patients treated with initial surgery alone had recurrence treated with SRS 2-3 months after resection. All these patients obtained local control and median survival was >10 months. Of the 13 patients who received WBRT followed by SRS as boost treatment, 92% had local control and mean overall survival was 7.3 months. Of 7 patients who received SRS after recurrence after WBRT, 100% had local control with median survival of 8.2 months. For 8 patients who received surgery followed by WBRT and SRS, local control was 50%; however, ultimate intracranial control was achieved in 7 of 8 patients with repeat SRS and surgical

    The use of three-dimensional replicas created using laserlithography has recently become popular for surgical planning and intraoperative navigation in plastic surgery and oral maxillofacial surgery. In this study, we investigated many clinical applications that we have been involved in regarding the production of three-dimensional replicas. We have also analyzed the features, application classes, and advantages of this method. As a result, clinical applications are categorized into three classes, which are 'three-dimensional shape recognition', 'simulated surgery', and 'template'. The distinct features of three-dimensional replicas are 'direct recognition', 'fast manipulation', and 'free availability'. Meeting the requirements of surgical planning and intraoperative navigation, they have produced satisfactory results in clinical applications. (author)

    The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

  7. Splenectomy with chemotherapy vs surgery alone as initial treatment for splenic marginal zone lymphoma (United States)

    Milosevic, Rajko; Todorovic, Milena; Balint, Bela; Jevtic, Miodrag; Krstic, Miodrag; Ristanovic, Elizabeta; Antonijevic, Nebojsa; Pavlovic, Mirjana; Perunicic, Maja; Petrovic, Milan; Mihaljevic, Biljana


    AIM: To evaluate the clinical characteristics of splenic marginal-zone lymphoma (SMZL) following antigen expression and the influence of therapeutic approaches on clinical outcome and overall survival (OS). METHODS: A total of 30 patients with typical histological and immunohistochemical SMZL patterns were examined. Splenectomy plus chemotherapy was applied in 20 patients, while splenectomy as a single treatment-option was performed in 10 patients. Prognostic factor and overall survival rate were analyzed. RESULTS: Complete remission (CR) was achieved in 20 (66.7%), partial remission (PR) in seven (23.3%), and lethal outcome due to disease progression occurred in three (10.0%) patients. Median survival of patients with a splenectomy was 93.0 mo and for patients with splenectomy plus chemotherapy it was 107.5 mo (Log rank = 0.056, P > 0.05). Time from onset of first symptoms to the beginning of the treatment (mean 9.4 mo) was influenced by spleen dimensions, as measured by computerized tomography and ultra-sound (t = 2.558, P = 0.018). Strong positivity (+++) of CD20 antigen expression in splenic tissue had a positive influence on OS (Log rank = 5.244, P 0.05) effects on the OS. The expression of other antigens (immunohistochemistry) also had no effect on survival-rate, as measured by a χ2 test (P > 0.05). CONCLUSION: Initial splenectomy combined with chemotherapy has been shown to be beneficial due to its advanced remission rate/duration; however, a larger controlled clinical study is required to confirm our findings.

  8. Treatment Success: Investigating Clinically Significant Change in Quality of Life Following Bariatric Surgery. (United States)

    Reynolds, Claire L; Byrne, Susan M; Hamdorf, Jeffrey M


    One of the most important outcomes following bariatric surgery is an improvement in health-related quality of life (QOL). This study aimed to explore what degree of weight loss is required after bariatric surgery in order to achieve a clinically significant change in QOL from pre-surgery to 4 to 5 years after surgery. Participants were assessed prior to having surgery (N = 280) and were invited to participate in a follow-up study 4 to 5 years after surgery. Sixty-seven of the original participants agreed to take part and completed a Web-based survey, which included the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire. Several analyses were conducted to examine the association between weight loss and clinically significant change in QOL. Mean age was 48.13 ± 10.37 years, 51 (76%) were female, 62 (92.5%) Caucasian, and mean baseline body mass index (BMI) was 41.11 ± 6.03 kg/m 2 . The mean percent of excess weight loss (EWL) was 46% (17% total weight loss), and 64% (n = 43) achieved a clinically significant change in QOL. The majority of those who lost ≥40% EWL had a clinically significant change in QOL, and their odds of achieving this change were 2.81 times higher than those that did not. Results indicated that an EWL of ≥40% may be sufficient for the majority of patients to achieve clinically significant change, but that ≥50% is a better predictor of clinically significant change.

    Kuchinka, Jakub; Nawacki, Łukasz; Bryk, Piotr; Matykiewicz, Jarosław; Wawrzycka, Iwona; Kozieł, Dorota; Rogula, Tomasz; Głuszek, Stanisław


    Obesity, at present, seems to be a very serious health problem all over the world. The surgery is said to be the most successful treatment of obesity. With the increase in the quantity of conducted bariatric procedures, the number of revision treatments increases as well. The aim of the study was to analyze the indications, results and complications after repeated bariatric surgeries. The repeated bariatric procedures performed in 2009-2015 have been retrospectively analyzed. The endpoint of the study was the evaluation of early surgical treatment results-up to 30th day after repeated surgery. Overall, amongs 103 obese patients with a BMI over 35 kg / m2, qualified for bariatric treatment 7 revision surgeries were conducted (6.8%). Two operations were carried out by laporotomy, other by laparoscopy. In the study group, neither any deaths were noted in perioperative period nor life-threatening complications. The frequency of complications-Surgical site infection and bleeding from the staple lines of stapler in the study group appeared to be 28.6%. Qualification for repeated bariatric surgeries should be based on a thorough analysis of the condition of the patient, previous outcome of the bariatric treatment: evaluation of weight loss as well as possible complications of the original surgery.

  14. Advanced nurse practitioner scheduled return clinic: a clinical audit of a quality initiative. (United States)

    Canty, Louise; Kearney, Anthony


    Emergency care settings in Ireland have struggled with a high volume of service users in recent years. This nationwide crisis led to the establishment of the National Emergency Medicine Programme Strategy in 2012, which identified two key performance indicators for efficiency in emergency care: the patient experience time, which should not exceed six hours from the time of registration to the time of discharge; and patients who do not wait for treatment (DNW) should make up less than 5% of those attending emergency care services. This article explores a quality initiative to improve DNW rates using scheduled return clinics, implemented by a group of advanced nurse practitioners in an emergency department in a Dublin hospital. It reviews the literature on scheduled return clinics and discusses the rationale for the initiative, its implementation, barriers to its introduction and an audit of its effectiveness. ©2018 RCN Publishing Company Ltd.

    Schneider, M; Werner, J; Weitz, J; Büchler, M W


    The structural organization of research facilities within a surgical university center should aim at strengthening the department's research output and likewise provide opportunities for the scientific education of academic surgeons. We suggest a model in which several independent research groups within a surgical department engage in research projects covering various aspects of surgically relevant basic, translational or clinical research. In order to enhance the translational aspects of surgical research, a permanent link needs to be established between the department's scientific research projects and its chief interests in clinical patient care. Importantly, a focus needs to be placed on obtaining evidence-based data to judge the efficacy of novel diagnostic and treatment concepts. Integration of modern technologies from the fields of physics, computer science and molecular medicine into surgical research necessitates cooperation with external research facilities, which can be strengthened by coordinated support programs offered by research funding institutions.

  17. Relation between Carcinoembryonic Antigen Levels in Colon Cancer Tissue and Serum Carcinoembryonic Antigen Levels at Initial Surgery and Recurrence. (United States)

    Saito, Gota; Sadahiro, Sotaro; Okada, Kazutake; Tanaka, Akira; Suzuki, Toshiyuki; Kamijo, Akemi


    Carcinoembryonic antigen (CEA) is widely used for postoperative surveillance of colon cancer. Even if serum CEA is negative at initial surgery, it may turn positive at recurrence. We investigated the relation between serum CEA levels and the immunohistochemical staining status of CEA in the primary and resected metastatic tissues. Out of 224 patients with recurrent colon cancer between 1998 and 2012, we studied 46 patients in whom serum CEA levels were measured and immunohistochemical staining for CEA was possible in the primary and metastatic tissues. The positive rate of serum CEA did not differ between initial surgery and recurrence, regardless of whether the cutoff value was set at 5 or 10 ng/ml (p = 0.829, p = 0.671). There was no relation between the CEA staining status and serum CEA level at initial surgery. However, the CEA staining status of metastatic tissue was significantly related to the serum CEA level at recurrence (p = 0.0046 and p = 0.0026). The immunohistochemical staining status of CEA in metastatic tissue is closely related to the serum CEA level. This finding suggests that serum CEA levels are influenced not only by the CEA production capacity of cancer cells but also by the ability of the surrounding tissue to release CEA into the blood. © 2016 The Author(s) Published by S.

  18. Clinical application of navigation surgery using augmented reality in the abdominal field. (United States)

    Okamoto, Tomoyoshi; Onda, Shinji; Yanaga, Katsuhiko; Suzuki, Naoki; Hattori, Asaki


    This article presents general principles and recent advancements in the clinical application of augmented reality-based navigation surgery (AR based NS) for abdominal procedures and includes a description of our clinical trial and subsequent outcomes. Moreover, current problems and future aspects are discussed. The development of AR-based NS in the abdomen is delayed compared with another field because of the problem of intraoperative organ deformations or the existence of established modalities. Although there are a few reports on the clinical use of AR-based NS for digestive surgery, sophisticated technologies in urology have often been reported. However, the rapid widespread use of video- or robot assisted surgeries requires this technology. We have worked to develop a system of AR-based NS for hepatobiliary and pancreatic surgery. Then we developed a short rigid scope that enables surgeons to obtain 3D view. We recently focused on pancreatic surgery, because intraoperative organ shifting is minimal. The position of each organ in overlaid image almost corresponded with that of the actual organ with about 5 mm of mean registration errors. Intraoperative information generated from this system provided us with useful navigation. However, AR-based NS has several problems to overcome such as organ deformity, evaluation of utility, portability or cost.

  19. Predictors of relaparotomy after nontrauma emergency general surgery with initial fascial closure. (United States)

    Kim, Jerry J; Liang, Mike K; Subramanian, Anuradha; Balentine, Courtney J; Sansgiry, Shubhada; Awad, Samir S


    Relaparotomy after emergency surgery for nontrauma intraabdominal catastrophes (NTIAC) is morbid. Our objective was to identify patients who likely will need on-demand relaparotomy after surgery for NTIAC. A retrospective chart review of patients from 1998 to 2008 identified cases of NTIAC surgery with fascial closure. Demographics, comorbidities, intraoperative findings, morbidity, and mortality were analyzed. Relaparotomy was defined as any return to the operating room with surgical re-entry of the abdominal cavity. A total of 129 patients underwent NTIAC surgery with fascial closure. Twenty-nine patients (22%) required relaparotomy and 100 patients (78%) did not. Multivariate analysis identified the following predictors of relaparotomy: peripheral vascular disease (P = .04), alcohol abuse (P = .02), body mass index of 29 kg/m(2) or greater (P = .04), the finding of any ischemic bowel (P = .02), and operating room latency of 60 hours or longer (P = .01). Patients with 2 or more of these predictors had a 55% risk of relaparotomy whereas patients with fewer than 2 of these predictors had a 9% risk (P surgery do worse when they require relaparotomy. We have identified preoperative and intraoperative predictors that may help identify patients at high risk of on-demand relaparotomy. Published by Elsevier Inc.

    Guan, Dandan; Lin, Hui; Lv, Zhenye; Xin, Ying; Meng, Kexin; Song, Xiangyang


    A new technique of oncoplastic breast surgery (OBS) using laparoscopically harvested pedicled omental flap has been developed in the past 10 years. This study aimed to evaluate the feasibility of this technique. Twenty-five patients underwent OBS using laparoscopically harvested omental flap. Operative time, blood loss, complications, recurrence, and cosmetic outcomes were prospectively analyzed. Between June 2010 and March 2014, 25 patients were recruited in our study. The surgery was performed successfully in 24 patients. All these patients recovered uneventfully after the surgery. Mean operative time was 310 min, ranging from 205 to 410 min. Mean blood loss was 70 ml, ranging from 20 to 150 ml. Patients were followed up for 32 months on average, ranging from 6 to 51 months. Four patients complained of mild epigastric discomfort. One patient had local recurrence and distant bone and liver metastasis and died 11 months after the surgery. One patient was diagnosed with metastases in the lung, bone, and liver without local recurrence 2 years after surgery. The cosmetic satisfaction rate was 91.7% and 95.8% by surgeon and patients, respectively. OBS with laparoscopically harvested omental flap might be a feasible technique with a good cosmetic outcome.

  3. Development and implementation of a clinical pathway approach to simulation-based training for foregut surgery. (United States)

    Miyasaka, Kiyoyuki W; Buchholz, Joseph; LaMarra, Denise; Karakousis, Giorgos C; Aggarwal, Rajesh


    Contemporary demands on resident education call for integration of simulation. We designed and implemented a simulation-based curriculum for Post Graduate Year 1 surgery residents to teach technical and nontechnical skills within a clinical pathway approach for a foregut surgery patient, from outpatient visit through surgery and postoperative follow-up. The 3-day curriculum for groups of 6 residents comprises a combination of standardized patient encounters, didactic sessions, and hands-on training. The curriculum is underpinned by a summative simulation "pathway" repeated on days 1 and 3. The "pathway" is a series of simulated preoperative, intraoperative, and postoperative encounters in following up a single patient through a disease process. The resident sees a standardized patient in the clinic presenting with distal gastric cancer and then enters an operating room to perform a gastrojejunostomy on a porcine tissue model. Finally, the resident engages in a simulated postoperative visit. All encounters are rated by faculty members and the residents themselves, using standardized assessment forms endorsed by the American Board of Surgery. A total of 18 first-year residents underwent this curriculum. Faculty ratings of overall operative performance significantly improved following the 3-day module. Ratings of preoperative and postoperative performance were not significantly changed in 3 days. Resident self-ratings significantly improved for all encounters assessed, as did reported confidence in meeting the defined learning objectives. Conventional surgical simulation training focuses on technical skills in isolation. Our novel "pathway" curriculum targets an important gap in training methodologies by placing both technical and nontechnical skills in their clinical context as part of managing a surgical patient. Results indicate consistent improvements in assessments of performance as well as confidence and support its continued usage to educate surgery residents

    To evaluate the radiological findings and clinical course of the complications arising after nonbiliay laparoscopic gastrointestinal surgery (NLGS). We retrospectively reviewed the clinical records of 131 patients who underwent NLGS (83 cases involving colorectal surgery, 18 splenectomies, 14 appendectomies, ten adrenalectomies, three lumbar sympathectomies, two Duhamel's operation, and one peptic ulcer perforation repair) over a four-year period. Among these 131 patients, the findings of fifteen in whom postoperative complications were confirmed were analysed. The radiologic examinations these patients underwent included CT (n=3D8), barium enema and fistulography (n=3D4), ultrasonography (n=3D3), ascending venography of the lower legs (n=3D2), and penile Doppler sonography (n=3D1). We evaluated the radiologic findings and clinical courses of early (within 2 weeks) and late (after 2 weeks) postoperative complications. Sixteen cases of postoperative complications developed in fifteen patients ; in 14 (17%) after colorectal surgery and in one (6%) after splenectomy. Eleven of the sixteen cases (69%) involved early complications, consisting of an abscess in three, ischemic colitis in two, hemoperitoneum in one, perforation of the colon in one, pancreatitis in one, recto-vaginal fistula in one, deep vein thrombosis after colorectal surgery in one, and abscess after splenectomy in one. The remaining five cases (31%) involved late complications which developed after colorectal surgery, comprising anastomosic site stricture in two, abdominal wall (trocar site) metastasis in one, colo-cutaneous fistula in one, and impotence in one. Among the 16 cases involving postoperative complications, recto-vaginal fistula, colon perforation, and abdominal wall metastasis were treated by surgery, while the other thirteen cases were treated conservatively.

    Sanoop K Zachariah


    Full Text Available Background: Single-incision laparoscopic surgery is considered as a more technically demanding procedure than the standard laparoscopic surgery. Based on an initial and early experience, single-incision laparoscopic appendectomy (LA was found to be technically advantageous for dealing with appendicitis in unusual anatomical locations. This study aims to highlight the technical advantages of single-incision laparoscopic surgery in dealing with the abnormally located appendixes and furthermore report a case of acute appendicitis occurring in a sub-gastric position, which is probably the first such case to be reported in English literature. Materials and Methods: A retrospective analysis of the first 10 cases of single-incision LA which were performed by a single surgeon is presented here. Results: There were seven females and three males. The mean age of the patients was 30.6 (range 18-52 years, mean BMI was 22.7 (range 17-28 kg/m 2 and the mean operative time was 85.5 (range 45-150 min. The mean postoperative stay was 3.6 (range 1-7 days. The commonest position of the appendix was retro-caecal (50% followed by pelvic (30%. In three cases the appendix was found to be in abnormal locations namely sub-hepatic, sub-gastric and deep pelvic or para-vesical or para-rectal. All these cases could be managed with this technique without any conversions Conclusion: Single-incision laparoscopic surgery appears to be a feasible and safe technique for dealing with appendicitis in rare anatomical locations. Appendectomy may be a suitable procedure for the initial training in single-incision laparoscopic surgery.

    Li, Jia; Lei, Tao; Liu, Yaming; Wei, Jingchao; Shen, Yong


    Adjacent segment disease (ASD) is one of the problematic complications following anterior cervical decompression and fusion (ACDF). The impact of additional surgery with instruments is still unknown. The objective of this study was to investigate the surgical outcomes of additional ACDF with instruments for symptomatic ASD after an initial ACDF using autogenous iliac grafts without instruments. A total of 56 patients who underwent an additional ACDF with instruments for symptomatic new radicular or myelopathic symptoms from ASD between 2006 and 2012. In this study, subjects were 30 men and 26 women with a mean age of 59.2 ± 9.7 years (range, 50-70 years) at revision surgery. Clinical evaluations were performed preoperatively and repeated at 3 years after operation. There were no cases of intraoperative complications, major neurological or vascular, pseudoarthrosis or wound complications. All of them reported significant improvements in JOA, NDI and VAS on arm pain and neck pain from the preoperative means (P< 0.05). According to our study, additional ACDF with instruments had achieved favorable clinical results on patients who underwent initial ACDF using autogenous iliac grafts without instruments for symptomatic new radiculopathy or myelopathy.

  8. Proposing a validated clinical app predicting hospitalization cost for extracranial-intracranial bypass surgery.

    Full Text Available United States healthcare reforms are focused on curtailing rising expenditures. In neurosurgical domain, limited or no data exists identifying potential modifiable targets associated with high-hospitalization cost for cerebrovascular procedures such as extracranial-intracranial (ECIC bypass. Our study objective was to develop a predictive model of initial cost for patients undergoing bypass surgery.In an observational cohort study, we analyzed patients registered in the Nationwide Inpatient Sample (2002-2011 that underwent ECIC bypass. Split-sample 1:1 randomization of the study cohort was performed. Hospital cost data was modelled using ordinary least square to identity potential drivers impacting initial hospitalization cost. Subsequently, a validated clinical app for estimated hospitalization cost is proposed (, 1533 patients [mean age: 45.18 ± 19.51 years; 58% female] underwent ECIC bypass for moyamoya disease [45.1%], cerebro-occlusive disease (COD [23% without infarction; 12% with infarction], unruptured [12%] and ruptured [4%] aneurysms. Median hospitalization cost was $37,525 (IQR: $16,225-$58,825. Common drivers impacting cost include Asian race, private payer, elective admission, hyponatremia, neurological and respiratory complications, acute renal failure, bypass for moyamoya disease, COD without infarction, medium and high volume centers, hospitals located in Midwest, Northeast, and West region, total number of diagnosis and procedures, days to bypass and post-procedural LOS. Our model was validated in an independent cohort and using 1000-bootstrapped replacement samples.Identified drivers of hospital cost after ECIC bypass could potentially be used as an adjunct for creation of data driven policies, impact reimbursement criteria, aid in-hospital auditing, and in the cost containment debate.

  9. [Clinical research status of laparoscopic gastric cancer surgery in China, Japan and South Korea]. (United States)

    Li, Guoxin; Chen, Xinhua; Yu, Jiang; Liu, Hao


    Laparoscopic surgery has its unique minimally invasive advantages, however, taking the complex and difficult D2 lymph node dissection for advanced gastric cancer into consideration, laparoscopic gastrectomy was only applied in the treatment of early gastric cancer at its preliminary stage. With the development of more than a decade, many multicenter clinical data have confirmed the safety, feasibility and effectiveness of laparoscopic radical gastrectomy for early gastric cancer. Based on high-quality evidence-based medicine evidence, laparoscopic gastrectomy has been recommended as an optional treatment for stage I( gastric cancer by the Japanese Gastric Cancer Treatment Guidelines 2014(ver.4). However, the safety and effectiveness of laparoscopic gastrectomy for advanced gastric cancer remains controversial due to the lack of high-level evidence-based clinical evidence. Currently, China, Japan and South Korea are trying to clarify its safety and effectiveness by conducting well-designed multicenter prospective randomized controlled trials. To date, CLASS-01 trial in China, whose secondary endpoint indicated that laparoscopic gastrectomy with D2 lymphadenectomy for advanced gastric cancer can be safely performed by experienced surgeons, has provided the highest level evidence for the controversy in the world. At ASCO 2016, the safety reports from Korea's KLASS-02 trial also presented the similar conclusion. The long-term oncologic outcomes of the both researches were particularly promising. Retrospecting the whole development of gastric cancer surgery, it is not difficult to find that its mainstream direction is gradually shifted from "extended and standardized surgical resection" to "individual and precise surgery" for the safety and postoperative quality of life. The new concept of minimally invasive surgery built on laparoscopic surgery emphasizes more than shortening the surgical incision, but minimizing tissue trauma and maximizing functional preservation.

    Malleshi, Suchetha N; Joshi, Mahasweta; Nair, Soumya K; Ashraf, Irshad


    Clinical audit is a quality improvement process that aims to improve patient care through a systematic review of care against explicit criteria. It is a cyclic and multidisciplinary process which involves a series of steps from planning the audit through measuring the performance to implementing and sustaining the change. Although audit contains some facets of research, it is essential to understand the difference between the two. Auditing can be done right from the record maintaining, diagnosis and treatment and postoperative evaluation and follow-up. The immense potential of clinical audit can be utilized only when open-mindedness and innovativeness are encouraged and evidence-based work culture is cultivated.

  11. Consecutive operative procedures in patients with Marfan syndrome up to 28 years after initial aortic root surgery. (United States)

    Puluca, Nazan; Burri, Melchior; Cleuziou, Julie; Krane, Markus; Lange, Rüdiger


    Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively. Overall, 73 patients (26 women) were selected for the study. The median age at 1st operation was 30 years (3-68 years). Indications for aortic root surgery were aneurysm (78%) and dissection (22%). Initially, 33 Bentall procedures and 40 valve-sparing root replacement procedures were performed, with a 97% rate of follow-up completion. The median follow up was 8 years (0-28 years). Survival at 1, 10 and 15 years was 100%, 85% and 82%, respectively. During follow-up monitoring, 48 subsequent procedures were performed in 33 patients (aorta, 23; aortic valve, 11; mitral valve, 7 and combined procedures, 7). The 30-day mortality rate after subsequent procedures was 4.2%. Freedom from subsequent operation and death (combined end-point) after 5, 10 and 15 years was 70%, 53% and 34%, respectively. After the initial surgery, subsequent procedures required in the setting of Marfan syndrome most often involve the remaining native aorta, followed by the aortic and mitral valves. The continued need for additional operative procedures remains high, even decades after the initial surgeries are undertaken. Therefore, long-term patient monitoring at specialized centres is imperative.

    The purpose of this study was to determine the diagnostic accuracy of synthetic MR sequences generated through post-acquisition processing of a single sequence measuring inherent R1, R2, and PD tissue properties compared with sequences acquired conventionally as part of a routine clinical pediatric brain MR exam. Thirty-two patients underwent routine clinical brain MRI with conventional and synthetic sequences acquired (22 abnormal). Synthetic axial T1, T2, and T2 fluid attenuation inversion recovery or proton density-weighted sequences were made to match the comparable clinical sequences. Two exams for each patient were de-identified. Four blinded reviewers reviewed eight patients and were asked to generate clinical reports on each exam (synthetic or conventional) at two different time points separated by a mean of 33 days. Exams were rated for overall and specific finding agreement (synthetic/conventional and compared to gold standard consensus review by two senior reviewers with knowledge of clinical report), quality, and diagnostic confidence. Overall agreement between conventional and synthetic exams was 97%. Agreement with consensus readings was 84% (conventional) and 81% (synthetic), p = 0.61. There were no significant differences in sensitivity, specificity, or accuracy for specific imaging findings involving the ventricles, CSF, brain parenchyma, or vasculature between synthetic or conventional exams (p > 0.05). No significant difference in exam quality, diagnostic confidence, or noise/artifacts was noted comparing studies with synthetic or conventional sequences. Diagnostic accuracy and quality of synthetically generated sequences are comparable to conventionally acquired sequences as part of a standard pediatric brain exam. Further confirmation in a larger study is warranted. (orig.)

    Greco, Elisa; Englesakis, Marina; Faulkner, Amy; Trojan, Boguslawa; Rotstein, Lorne E; Urbach, David R


    Quality of Care rounds, also known as Mortality and Morbidity conferences, are an important and time-honored forum for quality audit in clinical surgery services. The authors created a modification to their hospital's Quality of Care rounds by incorporating a clinical librarian, who assisted residents in conducting literature reviews related to clinical topics discussed during the rounds. The objective of this article is to describe the authors' experience with this intervention. The clinical librarian program has greatly improved the Quality of Care rounds by aiding in literature searches and quality of up-to-date, evidence-based presentations.

  4. Incidence and risk factors for lower limb lymphedema after gynecologic cancer surgery with initiation of periodic complex decongestive physiotherapy. (United States)

    Deura, Imari; Shimada, Muneaki; Hirashita, Keiko; Sugimura, Maki; Sato, Seiya; Sato, Shinya; Oishi, Tetsuro; Itamochi, Hiroaki; Harada, Tasuku; Kigawa, Junzo


    Lower limb lymphedema (LLL) is one of the most frequent postoperative complications of retroperitoneal lymphadenectomy for gynecologic cancer. LLL often impairs quality of life, activities of daily living, sleep, and sex in patients with gynecologic cancer. We conducted this study to evaluate the incidence and risk factors for LLL after gynecologic cancer surgery in patients who received assessment and periodic complex decongestive physiotherapy (CDP). We retrospectively reviewed 126 cases of gynecologic cancer that underwent surgery involving retroperitoneal lymphadenectomy at Tottori University Hospital between 2009 and 2012. All patients received physical examinations to detect LLL and underwent CDP by nurse specialists within several months after surgery. The International Society of Lymphology staging of lymphedema severity was used as the diagnostic criteria. Of 126 patients, 57 (45.2%) had LLL, comprising 45 and 12 patients with stage 1 and stage 2 LLL, respectively. No patient had stage 3 LLL. LLL was present in 37 (29.4%) patients at the initial physical examination. Multivariate analysis revealed that adjuvant concurrent chemoradiotherapy and age ≥ 55 years were independent risk factors for ≥ stage 2 LLL. To minimize the incidence of ≥ stage 2 LLL, gynecologic oncologists should be vigilant for this condition in patients who are ≥ 55 years and in those who undergo adjuvant chemoradiotherapy. Patients should be advised to have a physical assessment for LLL and to receive education about CDP immediately after surgery involving retroperitoneal lymphadenectomy for gynecologic cancer.

  5. Have Smartphones Contributed in the Clinical Progress of Oral and Maxillofacial Surgery? (United States)

    Dhuvad, Jigar M; Dhuvad, Mukesh M; Kshirsagar, Rajesh A


    Dental surgeons who encounter complex situations, such as those in unscheduled care, often have limited resources to provide a structured and specialty care. Therefore, there is always a need for cost-effective, easy to handle, easy to carry "Smartphones". The purpose of this paper was to undertake a review of literature on "Smartphone in Oral and Maxillofacial Surgery" online data-base and discuss the case series with emphasis on the role of attending dental surgeon and the maxillofacial surgeon. The available literature relevant to oral and maxillofacial surgery in online data-base of the United States National Library of Medicine: PubMed ( was searched. The inclusion criterion was to review the published clinical papers, abstracts and evidence based reviews on 'Uses of Smartphone in Oral and Maxillofacial Surgery'. Six articles were found with the search term "Smartphone in Oral and Maxillofacial Surgery" in the literature searched. Five articles met the inclusion criteria for the study. The relevant data was extracted, tabulated, and reviewed to draw evidence-based conclusions for uses of smartphone in oral and maxillofacial surgery. Utilization of smartphones in oral and maxillofacial surgery facilitate in differential diagnosis, treatment, follow up, prevention of the disease further and thereby improve the quality of patient care without requiring the presence of the maxillofacial surgeon in remote areas.

  6. Value of Prophylactic Postoperative Antibiotic Therapy after Bimaxillary Orthognathic Surgery: A Clinical Trial

    Directory of Open Access Journals (Sweden)

    Majid Eshghpour


    Full Text Available Introduction: Antibiotic therapy before or after orthognathic surgery is commonly recommended by surgeons to minimize the risk of wound infection. This article evaluates the value of Prophylactic antibiotic therapy in order to diminish the incidence of postoperative wound infection after orthognathic surgery.   Materials and Methods: Fifty candidates for bimaxillary orthognathic surgery were divided into cases and controls. Cefazolin (1g was administered intravenously to all participants 30 mins prior to surgery followed by a similar dose 4 hours later. Case-group patients ingested amoxicillin (500 mg orally for 7 days after surgery. Postoperative wound infection was assessed using clinical features, and the P-value significance was set at P  Results: Both groups were similar according to gender, age, and operating time. During the follow-up period no infection was observed in either the case or control group.   Conclusion:  The results of this study suggest that long-term postoperative antibiotic therapy is not essential for the prevention of postoperative infection, and that application of aseptic surgical technique and hygiene instruction after surgery are sufficient.

  7. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal carcinomatosis: initial experience in Oaxaca, Mexico. (United States)

    García-Matus, Rolando; Hernández-Hernández, Carlos Alberto; Leyva-García, Omar; Vásquez-Ciriaco, Sergio; Flores-Ayala, Guillermo; Navarro-Hernández, Quetzalli; Pérez-Bustamante, Gerardo; Valencia-Mijares, Norma Miriam; Esquivel, Jesus


    Peritoneal carcinomatosis (PC) has been traditionally considered a terminal disease with median survivals reported in the literature of 6 to 12 months. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are playing an ever increasing role in the treatment of these patients. Excellent results have been achieved in well-selected patients but there is a very steep learning curve when starting a new program. A program for peritoneal surface malignancies in which patients with PC of gastrointestinal or gynecological origin were treated using multimodality therapy with combinations of systemic therapy, cytoreductive surgery (CRS), and HIPEC was initiated in December 2007 at "Hospital Regional de Alta Especialidad de Oaxaca," Mexico. We present the results of our initial experience. From December 2007 to February 2011, 26 patients were treated with CRS and HIPEC. There were 21 female patients. Most common indication (46%) was recurrent ovarian cancer. Mean duration of surgery was 260 minutes. Mean Peritoneal Cancer Index was 9. Twenty-three (88.5%) patients had a complete cytoreduction. Major morbidity and mortality rates were 19.5 and 3.8 per cent, respectively. Mean hospital stay was 8 days. At a mean follow-up of 20 months, median survival has not been reached. Rigorous preoperative workup, strict selection criteria, and mentoring from an experienced cytoreductive surgeon are mandatory and extremely important when starting a center for PC.

  9. Risk stratification for the development of respiratory adverse events following vascular surgery using the Society of Vascular Surgery's Vascular Quality Initiative. (United States)

    Genovese, Elizabeth A; Fish, Larry; Chaer, Rabih A; Makaroun, Michel S; Baril, Donald T


    Postoperative respiratory adverse events (RAEs) are associated with high rates of morbidity and mortality in general surgery, however, little is known about these complications in the vascular surgery population, a frail subset with multiple comorbidities. The objective of this study was to describe the contemporary incidence of RAEs in vascular surgery patients, the risk factors for this complication, and the overall impact of RAEs on patient outcomes. The Vascular Quality Initiative was queried (2003-2014) for patients who underwent endovascular abdominal aortic repair, open abdominal aortic aneurysm repair, thoracic endovascular aortic repair, suprainguinal bypass, or infrainguinal bypass. A mixed-effects logistic regression model determined the independent risk factors for RAEs. Using a random 85% of the cohort, a risk prediction score for RAEs was created, and the score was validated using the remaining 15% of the cohort, comparing the predicted to the actual incidence of RAE and determining the area under the receiver operating characteristic curve. The independent risk of in-hospital mortality and discharge to a nursing facility associated with RAEs was determined using a mixed-effects logistic regression to control for baseline patient characteristics, operative variables, and other postoperative adverse events. The cohort consisted of 52,562 patients, with a 5.4% incidence of RAEs. The highest rates of RAEs were seen in current smokers (6.1%), recent acute myocardial infarction (10.1%), symptomatic congestive heart failure (9.9%), chronic obstructive pulmonary disease requiring oxygen therapy (11.0%), urgent and emergent procedures (6.4% and 25.9%, respectively), open abdominal aortic aneurysm repairs (17.6%), in situ suprainguinal bypasses (9.68%), and thoracic endovascular aortic repairs (9.6%). The variables included in the risk prediction score were age, body mass index, smoking status, congestive heart failure severity, chronic obstructive pulmonary

  10. Use of computer-based clinical examination to assess medical students in surgery. (United States)

    El Shallaly, Gamal E H A; Mekki, Abdelrahman M


    To improve the viewing of the video-projected structured clinical examination (ViPSCE), we developed a computerized version; the computer-based clinical examination (CCE). This was used to assess medical students' higher knowledge and problem solving skills in surgery. We present how we did this, test score descriptive statistics, and the students' evaluation of the CCE. A CCE in surgery was administered to assess a class of 43 final year medical students at the end of their surgical clerkship. Like the ViPSCE, the exam was delivered as a slide show, using a PowerPoint computer program. However, instead of projecting it onto a screen, each student used a computer. There were 20 slides containing either still photos or short video clips of clinical situations in surgery. The students answered by hand writing on the exam papers. At the end, they completed evaluation forms. The exam papers were corrected manually. Test score descriptive statistics were calculated and correlated with the students' scores in other exams in surgery. Administration of the CCE was straightforward. The test scores were normally distributed (mean = median = 4.9). They correlated significantly with the total scores obtained by the students in surgery (r = 0.68), and with each of the other exam modalities in surgery, such as the multiple choice and structured essay questions. Acceptability of the CCE to the students was high and they recommended the use of the CCE in other departments. CCE is feasible and popular with students. It inherits the validity and reliability of the ViPSCE with the added advantage of improving the viewing of the slides.

  11. Online and smartphone based cognitive behavioral therapy for bariatric surgery patients: Initial pilot study. (United States)

    Zhang, Melvyn W B; Ho, Roger C M; Cassin, Stephanie E; Hawa, Raed; Sockalingam, Sanjeev


    The respective rates of obesity in Canada and the United states are estimated to be 24.1% and 34.1%. Due to the increased incidence of obesity, Bariatric surgery has been recognized as one of the treatment options. Despite the success of Bariatric surgery, studies have proposed that it has neglected the contributions of other factors, such as psychological factors in the causation as well as the maintenance of obesity amongst individuals. Cognitive behavioral therapy (CBT) is largely a psychosocial intervention that has been shown to be efficacious, as studies have demonstrated that even brief CBT interventions could help in the reduction of binge eating and maintenance of weight loss. Previously identified problems with regards to the integration and the provision of such interventions include that of geographical barriers. In order to overcome the geographical barriers, telephone-based CBT has been conceptualized. Over the past decade, there has been massive advancement and development in Internet, Web-based and smartphone technologies, but there is still a paucity of applications in this area. Our current research objective is to determine if bariatric surgery patients will be receptive towards an online and smartphone based CBT intervention. The Bariatric Surgery Online CBT portal and Smartphone companion application was developed between July 2013 and December 2013. A low-cost methodology of developing the online portal was adopted. In terms of development, 4 core development phases were adopted. These included that of: a) Formulation of users' requirements, b) System design and development, c) System evaluation and d) System deployment and pilot application. The bariatric surgery workgroup from the Toronto Western Hospital helped with the recruitment of the subjects from the outpatient specialist service. Links to the web-portal was provided to each of the participants recruited. Since the inception of the online portal to date, in terms of usage rates, there

  12. One-Stop Clinic Utilization in Plastic Surgery: Our Local Experience and the Results of a UK-Wide National Survey (United States)

    Gorman, Mark; Coelho, James; Gujral, Sameer; McKay, Alastair


    Introduction. “See and treat” one-stop clinics (OSCs) are an advocated NHS initiative to modernise care, reducing cancer treatment waiting times. Little studied in plastic surgery, the existing evidence suggests that though they improve care, they are rarely implemented. We present our experience setting up a plastic surgery OSC for minor skin surgery and survey their use across the UK. Methods. The OSC was evaluated by 18-week wait target compliance, measures of departmental capacity, and patient satisfaction. Data was obtained from 32 of the 47 UK plastic surgery departments to investigate the prevalence of OSCs for minor skin cancer surgery. Results. The OSC improved 18-week waiting times, from a noncompliant mean of 80% to a compliant 95% average. Department capacity increased 15%. 95% of patients were highly satisfied with and preferred the OSC to a conventional service. Only 25% of UK plastic surgery units run OSCs, offering varying reasons for not doing so, 42% having not considered their use. Conclusions. OSCs are underutilised within UK plastic surgery, where a significant proportion of units have not even considered their benefit. This is despite associated improvements in waiting times, department capacity, and levels of high patient satisfaction. We offer our considerations and local experience instituting an OSC service.

  13. Clinical Experiences of Non-fusion Dynamic Stabilization Surgery for Adjacent Segmental Pathology after Lumbar Fusion. (United States)

    Lee, Soo Eon; Jahng, Tae-Ahn; Kim, Hyun-Jib


    As an alternative to spinal fusion, non-fusion dynamic stabilization surgery has been developed, showing good clinical outcomes. In the present study, we introduce our surgical series, which involves non-fusion dynamic stabilization surgery for adjacent segment pathology (ASP) after lumbar fusion surgery. Fifteen patients (13 female and 2 male, mean age of 62.1 years) who underwent dynamic stabilization surgery for symptomatic ASP were included and medical records, magnetic resonance images (MRI), and plain radiographs were retrospectively evaluated. Twelve of the 15 patients had the fusion segment at L4-5, and the most common segment affected by ASP was L3-4. The time interval between prior fusion and later non-fusion surgery was mean 67.0 months. The Visual Analog Scale and Oswestry Disability Index showed values of 7.4 and 58.5% before the non-fusion surgery and these values respectively declined to 4.2 and 41.3% postoperatively at 36 months (p=0.027 and p=0.018, respectively). During the mean 44.8 months of follow-up, medication of analgesics was also significantly reduced. The MRI grade for disc and central stenosis identified significant degeneration at L3-4, and similar disc degeneration from lateral radiographs was determined at L3-4 between before the prior fusion surgery and the later non-fusion surgery. After the non-fusion surgery, the L3-4 segment and the proximal segment of L2-3 were preserved in the disc, stenosis and facet joint whereas L1-2 showed disc degeneration on the last MRI (p=0.032). Five instances of radiologic ASP were identified, showing characteristic disc-space narrowing at the proximal segments of L1-2 and L2-3. However, no patient underwent additional surgery for ASP after non-fusion dynamic stabilization surgery. The proposed non-fusion dynamic stabilization system could be an effective surgical treatment for elderly patients with symptomatic ASP after lumbar fusion.

  14. The use of bioabsorbable staple line reinforcement for circular stapler (BSG "Seamguard") in colorectal surgery: initial experience. (United States)

    Franklin, Morris E; Ramila, Guillermo Portillo; Treviño, Jorge M; González, John J; Russek, Karla; Glass, Jeffrey L; Kim, Greg


    Of all the complications associated with colorectal surgery, the most devastating and constant, despite all techniques being performed properly is anastomotic leakage, especially in left colon and rectal resections with rates as high as 50% when the rectum is involved. In 2005, our center published the preliminary experience with the use of linear staple line reinforcement for colon surgery. The purpose of this paper is to present a series of cases using a new conformation of bioabsorbable reinforcement for circular staplers in 5 patients, 2 patients with rectal cancer, 2 patients with diverticular disease, and 1 patient with sigmoid cancer. These initial data are very promising and has encouraged us to continue using this device on further patients.

  15. Consequences of insufficient treatment planning for flapless implant surgery for a mandibular overdenture: a clinical report. (United States)

    Bidra, Avinash S


    Flapless implant surgery is an emerging modality of treatment in implant dentistry that is known to offer several advantages. However, this procedure is inadvisable for situations where there is an absence of labial/buccal bone, reduced width of alveolar ridge, or a need for alveoloplasty to create prosthetic space. This clinical report describes the biologic and prosthodontic consequences of placing implants through flapless surgery and without preoperative treatment planning. Importance of proper treatment planning and a detailed discussion of prosthetic/restorative space analysis are discussed.

  16. Awake surgery between art and science. Part I: clinical and operative settings. (United States)

    Talacchi, Andrea; Santini, Barbara; Casagrande, Francesca; Alessandrini, Franco; Zoccatelli, Giada; Squintani, Giovanna M


    Awake surgery requires coordinated teamwork and communication between the surgeon and the anesthesiologist, as he monitors the patient, the neuroradiologist as he interprets the images for intraoperative confirmation, and the neuropsychologist and neurophysiologist as they evaluate in real-time the patient's responses to commands and questions. To improve comparison across published studies on clinical assessment and operative settings in awake surgery, we reviewed the literature, focusing on methodological differences and aims. In complex, interdisciplinary medical care, such differences can affect the outcome and the cost-benefit ratio of the treatment. Standardization of intraoperative mapping and related controversies will be discussed in Part II.

  17. Using Texting for Clinical Communication in Surgery: A Survey of Academic Staff Surgeons. (United States)

    Firdouse, Mohammed; Devon, Karen; Kayssi, Ahmed; Goldfarb, Jeremy; Rossos, Peter; Cil, Tulin D


    Text messaging has become ubiquitous and is being increasingly used within the health care system. The purpose of this study was to understand texting practices for clinical communication among staff surgeons at a large academic institution. Staff surgeons in 4 subspecialties (vascular, plastics, urology, and general surgery) were surveyed electronically. A total of 62 surgeons from general surgery (n = 33), vascular surgery (n = 6), plastic surgery (n = 13), and urology (n = 10) completed the study (response rate 30%). When conveying urgent patient-related information, staff surgeons preferred directly calling other staff surgeons (61.5%) and trainees (58.8%). When discussing routine patient information, staff surgeons used email to reach other staff surgeons (54.9%) but preferred texting (62.7%) for trainees. The majority of participants used texting because it is fast (65.4%), convenient (69.2%) and allows transmitting information to multiple recipients simultaneously (63.5%). Most felt that texting enhances patient care (71.5%); however, only half believed that it enhanced trainees' educational experiences. The majority believed that texting identifiable patient information breaches patient confidentiality. Our data showed high adoption of text messaging for clinical communication among surgeons, particularly with trainees. The majority of surgeons acknowledge security concerns inherent in texting for patient care. Existing mobile communication platforms fail to meet the needs of academic surgeons. Further research should include guidelines related to texting in clinical practice, educational implications of texting, and technologies to better meet the needs of clinicians working in an academic surgical settings.

  18. Relationship Between Academic Performance and Student Self-Assessment of Clinical Performance in the College of Podiatric Medicine and Surgery. (United States)

    Yoho, Robert M; Vardaxis, Vassilios; Millonig, Kelsey


    Student self-assessment is viewed as an important tool in medical education. We sought to identify the relationship between student academic performance and third-year clinical performance self-assessment. No such study exists in podiatric medical education. Third-year podiatric medical students from the classes of 2012 through 2014 completed a self-assessment of their performance for each of five broad clinical podiatric medical domains (Professionalism, Medicine, Radiology, Surgery, and Biomechanics/Orthopedics). The assessment was completed after students finished the first 12 weeks of their third-year clinical rotations (PRE) and a second time at the conclusion of the third year (POST). The mean self-assessment score for PRE and POST surveys for all combined domains was determined for each student. This mean was compared with the student's 3-year cumulative grade point average (GPA). Students' clinical experiences for the year were essentially identical. No statistically significant correlation was identified between cumulative GPA and the PRE and POST clinical self-assessments or with the change between PRE and POST assessments based on the Pearson correlation test for each class separately or on the pooled data. Published studies in allopathic medical education have shown that students with lower GPAs tend to rate their clinical performance higher in initial clinical performance self-assessment. Our results show that student academic performance was not correlated with clinical performance self-assessment. These findings may be due to the explicit description of successful clinical competency completion, the orientation students receive before the start of clinical training, and the continuous feedback received from clinical preceptors.

    Full Text Available Background: Golimumab is a TNF-blocking agent indicated as a second-line therapy in ulcerative colitis. Purpose: To research the effectiveness and safety of golimumab in patients with ulcerative colitis in clinical practice. Methods: Retrospective study of the effectiveness and safety of golimumab in patients with ulcerative colitis. All patients received golimumab 200 mg subcutaneously at week 0, and golimumab 100 mg subcutaneously at week 2. After the induction treatment, each patient received 50 mg sc. every 4 weeks in patients with body weight less than 80 kg, and 100 mg every 4 weeks in patients with body weight greater than or equal to 80 kg. Results: Study of a group of 23 ulcerative colitis patients, 7 of whom were naive to any anti-TNF therapy, and 16 patients who had previously been treated with an anti-TNF agent other than golimumab (non-naive patients. The average treatment time with golimumab was 14.3 weeks. Globally, withdrawal of corticosteroids was observed in 74% of cases. Clinical response was observed in 85.5% of patients who had not received biological treatment previously, and in patients who had previously received biological treatment the response rate was 75%. Conclusions: In this short study, golimumab seems to be an alternative treatment in naive and non-naive anti-TNF ulcerative colitis patients. It is also a safe therapy, given that there were no adverse effects in the patients studied.

    Sánchez-Margallo, Francisco M; Sánchez-Margallo, Juan A; Moyano-Cuevas, José L; Pérez, Eva María; Maestre, Juan


    Surgical environments require special aseptic conditions for direct interaction with the preoperative images. We aim to test the feasibility of using a set of gesture control sensors combined with voice control to interact in a sterile manner with preoperative information and an integrated operating room (OR) during laparoscopic surgery. Two hepatectomies and two partial nephrectomies were performed by three experienced surgeons in a porcine model. The Kinect, Leap Motion, and MYO armband in combination with voice control were used as natural user interfaces (NUIs). After surgery, surgeons completed a questionnaire about their experience. Surgeons required <10 min training with each NUI. They stated that NUIs improved the access to preoperative patient information and kept them more focused on the surgical site. The Kinect system was reported as the most physically demanding NUI and the MYO armband in combination with voice commands as the most intuitive and accurate. The need to release one of the laparoscopic instruments in order to use the NUIs was identified as the main limitation. The presented NUIs are feasible to directly interact in a more intuitive and sterile manner with the preoperative images and the integrated OR functionalities during laparoscopic surgery.

  1. Clinical Application of Three-Dimensional Printing Technology in Craniofacial Plastic Surgery (United States)

    Kim, Namkug


    Three-dimensional (3D) printing has been particularly widely adopted in medical fields. Application of the 3D printing technique has even been extended to bio-cell printing for 3D tissue/organ development, the creation of scaffolds for tissue engineering, and actual clinical application for various medical parts. Of various medical fields, craniofacial plastic surgery is one of areas that pioneered the use of the 3D printing concept. Rapid prototype technology was introduced in the 1990s to medicine via computer-aided design, computer-aided manufacturing. To investigate the current status of 3D printing technology and its clinical application, a systematic review of the literature was conducted. In addition, the benefits and possibilities of the clinical application of 3D printing in craniofacial surgery are reviewed, based on personal experiences with more than 500 craniofacial cases conducted using 3D printing tactile prototype models.

    The aim of this study was to determine the clinical effectiveness and cost-effectiveness of laparoscopic, laparoscopically assisted (hereafter together described as laparoscopic surgery) and hand-assisted laparoscopic surgery (HALS) in comparison with open surgery for the treatment of colorectal cancer. Electronic databases were searched from 2000 to May 2005. A review of economic evaluations was undertaken by the National Institute for Health and Clinical Excellence in 2001. This review was updated from 2000 until July 2005. Data from selected studies were extracted and assessed. Dichotomous outcome data from individual trials were combined using the relative risk method and continuous outcomes were combined using the Mantel-Haenszel weighted mean difference method. Summaries of the results from individual patient data (IPD) meta-analyses were also presented. An economic evaluation was also carried out using a Markov model incorporating the data from the systematic review. The results were first presented as a balance sheet for comparison of the surgical techniques. It was then used to estimate cost-effectiveness measured in terms of incremental cost per life-year gained and incremental cost per quality-adjusted life-year (QALY) for a time horizon up to 25 years. Forty-six reports on 20 studies [19 randomised controlled trials (RCTs) and one IPD meta-analysis] were included in the review of clinical effectiveness. The RCTs were of generally moderate quality with the number of participants varying between 16 and 1082, with 10 having less than 100 participants. The total numbers of trial participants who underwent laparoscopic or open surgery were 2429 and 2139, respectively. A systematic review of four papers suggested that laparoscopic surgery is more costly than open surgery. However, the data they provided on effectiveness was poorer than the evidence from the review of effectiveness. The estimates from the systematic review of clinical effectiveness were

  3. Clinical negligence claims in pediatric surgery in England: pattern and trends. (United States)

    Thyoka, Mandela


    We hypothesized that there has been an increase in the number of successful litigation claims in pediatric surgery in England. Our aim was to report the incidence, causes, and costs of clinical negligence claims against the National Health Service (NHS) in relation to pediatric surgery. We queried the NHS Litigation Authority (NHSLA) on litigation claims among children undergoing pediatric surgery in England (2004-2012). We decided a priori to only examine closed cases (decision and payment made). Data included year of claim, year of payment of claim, payment per claim, paid-to-closed ratio, and severity of outcome of clinical incident. Out of 112 clinical negligence claims in pediatric surgery, 93 (83%) were finalized-73 (65%) were settled and damages paid to the claimant and 20 (18%) were closed with no payment, and 19 (17%) remain open. The median payment was £13,537 (600-500,000) and median total cost borne by NHSLA was £31,445 (600-730,202). Claims were lodged at a median interval of 2 (0-13) years from time of occurrence with 55 (75%) cases being settled within the 3 years of being received. The commonest reasons for claims were postoperative complications (n=20, 28%), delayed treatment (n=16, 22%), and/or diagnosis (n=14, 19%). Out of 73, 17 (23%) closed claims resulted in case fatality. Conclusion: Two-thirds of all claims in pediatric surgery resulted in payment to claimant, and the commonest reasons for claims were postoperative complications, delayed treatment, and/or diagnosis. Nearly a quarter of successful claims were in cases where negligence resulted in case fatality. Pediatric surgeons should be aware of common diagnostic and treatment shortfalls as high-risk areas of increased susceptibility to clinical negligence claims.

    Introduction Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. Methods From March/2012 thru March 2015, 37 patients consecutively underwent conservative operations of the aortic valve and/or aortic root. Mean age was 48±16 years and 81% were males. The aortic valve was bicuspid in 54% and tricuspid in the remaining. All were operated with the aid of intraoperative transesophageal echocardiography. Surgical techniques consisted of replacing the aortic root with a Dacron graft whenever it was dilated or aneurysmatic, using either the remodeling or the reimplantation technique, besides correcting leaflet prolapse when present. Patients were sequentially evaluated with clinical and echocardiographic studies and mean follow-up time was 16±5 months. Results Thirty-day mortality was 2.7%. In addition there were two late deaths, with late survival being 85% (CI 95% - 68%-95%) at two years. Two patients were reoperated due to primary structural valve failure. Freedom from reoperation or from primary structural valve failure was 90% (CI 95% - 66%-97%) and 91% (CI 95% - 69%-97%) at 2 years, respectively. During clinical follow-up up to 3 years, there were no cases of thromboembolism, hemorrhage or endocarditis. Conclusions Although this represents an initial series, these data demonstrates that aortic valve repair and/or valve sparing aortic root surgery can be performed with satisfactory immediate and short-term results.

    Full Text Available Deep brain stimulation (DBS is an effective treatment for multiple movement disorders and shows substantial promise for the treatment of some neuropsychiatric and other disorders of brain neurocircuitry. Optimal neuroanatomical lead position is a critical determinant of clinical outcomes in DBS surgery. Lead migration, defined as an unintended post-operative displacement of the DBS lead, has been previously reported. Despite several reports, however, there have been no systematic investigations of this issue. This study aimed to: 1 quantify the incidence of lead migration in a large series of DBS patients, 2 identify potential risk factors contributing to DBS lead migration, and 3 investigate the practical importance of this complication by correlating its occurrence with clinical outcomes.A database of all DBS procedures performed at UF was queried for patients who had undergone multiple post-operative DBS lead localization imaging studies separated by at least two months. Bilateral DBS implantation has commonly been performed as a staged procedure at UF, with an interval of six or more months between sides. To localize the position of each DBS lead, a head CT is acquired ~4 weeks after lead implantation and fused to the pre-operative targeting MRI. The fused targeting images (MR + stereotactic CT acquired in preparation for the delayed second side lead implantation provide an opportunity to repeat the localization of the first implanted lead. This paradigm offers an ideal patient population for the study of delayed DBS lead migration because it provides a large cohort of patients with localization of the same implanted DBS lead at two time points. The position of the tip of each implanted DBS lead was measured on both the initial post-operative lead localization CT and the delayed CT. Lead tip displacement, intracranial lead length, and ventricular indices were collected and analyzed. Clinical outcomes were characterized with validated rating

  7. Virtual reality in the treatment of body image disturbances after bariatric surgery: a clinical case. (United States)

    Riva, Giuseppe; Cárdenas-López, Georgina; Duran, Ximena; Torres-Villalobos, Gonzalo M; Gaggioli, Andrea


    Bariatric surgery is an operation on the stomach and/or intestines that helps patients with extreme obesity to lose weight. Even if bariatric surgery, compared with traditional obesity treatment, is more effective in reducing BMI, this approach does not achieve equal results in every patient. More, following bariatric surgery common problems are body image dissatisfaction and body disparagement: there is a significant difference between the weight loss clinicians consider successful (50% of excess weight) and the weight loss potential patients expect to achieve (at least 67% of the excess weight). The paper discusses the possible role of virtual reality (VR) in addressing this problem within an integrated treatment approach. More, the clinical case of a female bariatric patient who experienced body dissatisfaction even after a 30% body weight loss and a 62% excess body weight loss, is presented and discussed.

    This study aimed to evaluate the initial outcomes of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in terms of tumor response and safety. HCC patients who were not indicated for standard curative local modalities and who were treated with PBT at Samsung Medical Center from January 2016 to February 2017 were enrolled. Toxicity was scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was evaluated using modified Response Evaluation Criteria in Solid Tumors (mRECIST). A total of 101 HCC patients treated with PBT were included. Patients were treated with an equivalent dose of 62-92 GyE 10 . Liver function status was not significantly affected after PBT. Greater than 80% of patients had Child-Pugh class A and albumin-bilirubin (ALBI) grade 1 up to 3-months after PBT. Of 78 patients followed for three months after PBT, infield complete and partial responses were achieved in 54 (69.2%) and 14 (17.9%) patients, respectively. PBT treatment of HCC patients showed a favorable infield complete response rate of 69.2% with acceptable acute toxicity. An additional follow-up study of these patients will be conducted.

    Full Text Available ABSTRACT OBJECTIVE: To identify the characteristics of patients with spinal cord injury (SCI undergoing surgery. METHODS: Previously, 321 patients with SCI were selected. Clinical and socio-demographic variables were collected. RESULTS: A total of 211 patients were submitted to surgery. Fall and injuries in the upper cervical and lumbosacral regions were associated with conservative treatment. Patients with lesions in the lower cervical spine, worse neurological status, and unstable injuries were associated with surgery. Individuals undergoing surgery were associated with complications after treatment. The authors assessed whether age influenced the characteristics of patients submitted to surgery. Subjects with <60 years of age were associated with motorcycle accidents and the morphologies of injury were fracture-dislocation. Elderly individuals were associated to fall, SCI in the lower cervical spine and the morphology of injury was listhesis. Subsequently, the authors analyzed the gender characteristics in these patients. Women who suffered car accidents were associated to surgery. Women were associated with paraparesis and the morphologic diagnosis was fracture-explosion, especially in the thoracolumbar transition and lumbosacral regions. Men who presented traumatic brain injury and thoracic trauma were related to surgery. These individuals had a worse neurological status and were associated to complications. Men and the cervical region were most affected, thereby, these subjects were analyzed separately (n= 92. The presence of complications increased the length of hospital stay. The simultaneous presence of morphological diagnosis, worst neurological status, tetraplegia, sensory, and motor alterations were associated with complications. Pneumonia and chest trauma were associated with mortality. CONCLUSION: These factors enable investments in prevention, rehabilitation, and treatment.

  10. Robotic surgery for rectal cancer: current immediate clinical and oncological outcomes. (United States)

    Araujo, Sergio Eduardo Alonso; Seid, Victor Edmond; Klajner, Sidney


    Laparoscopic rectal surgery continues to be a challenging operation associated to a steep learning curve. Robotic surgical systems have dramatically changed minimally invasive surgery. Three-dimensional, magnified and stable view, articulated instruments, and reduction of physiologic tremors leading to superior dexterity and ergonomics. Therefore, robotic platforms could potentially address limitations of laparoscopic rectal surgery. It was aimed at reviewing current literature on short-term clinical and oncological (pathological) outcomes after robotic rectal cancer surgery in comparison with laparoscopic surgery. A systematic review was performed for the period 2002 to 2014. A total of 1776 patients with rectal cancer underwent minimally invasive robotic treatment in 32 studies. After robotic and laparoscopic approach to oncologic rectal surgery, respectively, mean operating time varied from 192-385 min, and from 158-297 min; mean estimated blood loss was between 33 and 283 mL, and between 127 and 300 mL; mean length of stay varied from 4-10 d; and from 6-15 d. Conversion after robotic rectal surgery varied from 0% to 9.4%, and from 0 to 22% after laparoscopy. There was no difference between robotic (0%-41.3%) and laparoscopic (5.5%-29.3%) surgery regarding morbidity and anastomotic complications (respectively, 0%-13.5%, and 0%-11.1%). Regarding immediate oncologic outcomes, respectively among robotic and laparoscopic cases, positive circumferential margins varied from 0% to 7.5%, and from 0% to 8.8%; the mean number of retrieved lymph nodes was between 10 and 20, and between 11 and 21; and the mean distal resection margin was from 0.8 to 4.7 cm, and from 1.9 to 4.5 cm. Robotic rectal cancer surgery is being undertaken by experienced surgeons. However, the quality of the assembled evidence does not support definite conclusions about most studies variables. Robotic rectal cancer surgery is associated to increased costs and operating time. It also seems to be

    Sarah M. Westberg, Pharm.D.


    Full Text Available Objectives: To develop and deliver an effective pharmacist-led educational initiative to clinic staff to advance medication reconciliation in the electronic medical record of an outpatient internal medicine clinic.Methods: An educational initiative designed to improve the ability of nursing staff in medication reconciliation was launched in the outpatient internal medicine clinic of a regional healthcare system. The education was provided by the pharmacist to clinic nursing staff, including registered nurses, licensed practical nurses, and certified medical assistants. The impact of this training was measured through pre-initiation and post-implementation surveys, competency assessments and an audit. Results: The educational initiative was successfully designed and delivered to clinic nursing staff. Assessment of the initiative found that all nursing staff completing competency assessments successfully passed. Pre-initiation- and post-implementation- survey responses on the self-assessed ability to gather and document accurate medication lists did not show significant changes. Informal observations in the clinic indicated that this initiative changed the culture of the clinic, creating increased awareness of the importance of accurate medications and increased emphasis on medication reconciliation.Conclusions: The expertise of pharmacists can be utilized to educate nursing staff on the skills and abilities necessary to gather and document accurate medication lists. This study did not find measurable changes in the accuracy of medication lists in this clinic. Future research is needed to determine the best methods to train health professionals in medication reconciliation to ensure accurate medication lists in the outpatient setting.

    Insufficient weight loss or persistent abdominal complaints are reasons for revisionary operations in bariatric surgery. The selection of the secondary procedure is influenced by clinical and by patho-anatomical factors like the size of the gastric pouch. The purpose of this study was to evaluate multi-slice computed tomography (MSCT)-based volumetric assessment of gastric pouches, gastric sleeves, and anastomoses in patients after bariatric surgery. Twenty-six patients after bariatric surgery received abdominal MSCT immediately after oral administration of an ionic contrast agent solution and intravenous administration of buthylscopalamine. Indications were insufficient weight loss after primary operation, persistent upper abdominal complaints, and decline of bariatric analysis and reporting outcomes system (BAROS) score. The gastric volumes, diameter of the gastrojejunostomy, and the proximal part of the Roux limb were measured on volume rendering images and freely angulated reformations. Evaluation of gastric volumes was successful in 25 examinations (96%). The diameters of gastrojejunostomy as well as the dimensions of the Roux limb were evaluable in all cases. After gastric bypass surgery, a pouch volume >30 ml was found in ten, a widening of the gastrojejunostomy in eight, and a dilated Roux limb in six cases. Two patients presented a combination of a wide anastomosis and a strongly dilated Roux limb. Patients after biliopancreatic diversion had gastric volumes between 210 and 840 ml. Other findings were a fistula, an intragastral stenosis, and internal hernias. MSCT allows crucial patho-anatomical measurements and provides helpful information for selecting the appropriate revisionary operation after bariatric surgery.

    The feasibility, safety and oncological outcomes of laparoscopic surgery for transverse and descending colon cancers in a community hospital setting were evaluated. Twenty-six patients with transverse or descending colon cancers who underwent laparoscopic surgery at our hospital were included in this retrospective analysis (group A). Their outcomes were compared with those of 71 patients who underwent laparoscopic surgery for colon cancer at other tumor sites (group B). There were no significant differences between the two groups in terms of operative time, estimated blood loss, postoperative hospital stay and morbidity rate. Extended lymphadenectomy was performed more frequently and the number of harvested lymph nodes was significantly higher in group B than in group A. However, no recurrence developed in group A, while recurrence occurred in four patients from group B. The 3-year disease-free survival rates were 100% for group A and 93.5% for group B. The 3-year overall survival rates were 100% for group A and 91.6% for group B. Laparoscopic surgery for transverse and descending colon cancers can be performed safely with oncological validity in a community hospital setting, provided there is careful selection of the patients and adequate lymphadenectomy considering the clinical stage of their disease. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

  16. Minimally invasive video-assisted parathyroidectomy. Initial experience in a General Surgery Department. (United States)

    Dobrinja, C; Trevisan, G; Liguori, G


    The aim of this study is to analyze our preliminary results from minimally invasive video-assisted parathyroidectomy (MIVAP) and demonstrate the feasibility of MIVAP also in non-referral centers. During a period from June 2005 to January 2008, in the General Surgery Department of University of Trieste, we operated on 39 patients with primary hyperparathyroidism (pHPT). MIVAP by an anterior approach was proposed for 23 (59%) patients with sporadic pHPT and one unequivocally enlarged parathyroid gland on pre-operative ultrasound and 99mTc-SestaMIBI scintigraphy without associated goiter and without previous neck surgery. Intra-operatively, a quick parathyroid assay was used during the last 11 surgical procedures. All patients underwent pre-operative and post-operative investigations of calcemia, phoshoremia and PTH levels and vocal cord function. Age, operative times, pathologic findings, post-operative pain, calcemia, length of hospital stay, cosmetic results, and complications were retrospectively analyzed. MIVAP was successfully accomplished in 22 cases. Conversion to standard cervicotomy was required in one patient (4.34%). Mean operative time was 67 min. Post-operative complications included 1 (4.34%) transient hypocalcemia. No laryngeal nerve palsies, no definitive hypocalcemias, no persistent pHPT and no recurrent pHPT were observed. The cosmetic result was excellent in all cases. Our preliminary results demonstrate that MIVAP for localized single-gland adenoma, after adequate training, seems to be feasible with significant advantages, especially in terms of cosmetic results, post-operative pain, and post-operative recovery even in a General Surgery Department, if performed by a dedicated team, with a sufficient and specific activity volume.

  18. Initial experience with laparoscopic single-incision triangulated umbilical surgery (SITUS) in simple and radical nephrectomy. (United States)

    Nagele, Udo; Walcher, Ute; Herrmann, Thomas R W


    New transumbilical laparoendoscopic procedures are an emerging field in urologic surgery. We introduced the concept of single-incision triangulated umbilical surgery (SITUS) in 2009. SITUS technique uses straight optics and instruments in a triangulated fashion via three trocars placed through an umbilical incision resulting in a familiar laparoscopic environment. Aim of the study was to demonstrate the feasibility of SITUS in simple and radical nephrectomy in daily routine. From October 2009 to July 2010, in 3 patients with cirrhotic kidneys a simple and in 12 patients a radical nephrectomy was performed in SITUS technique. The umbilical fold was incised at three-fourth of its circumference; in the patient with radical nephrectomy, additionally small "c"-shaped skin flaps were removed. After achieving a pneumoperitoneum by Verres technique, a 5-mm camera port and then a cranial 5 mm and a caudal 11 mm working trocar were placed with at a distance of 5-10 cm with the aid of two Langenbeck hooks, thus allowing triangulation except in the radical nephrectomy patients, where an 11-mm caudal trocar (Endopath, Ethicon, Hamburg, GER) was used. Using long conventional laparoscopic instruments, En-Seal pressure coagulator and dissector (Erbe, Tuebingen, Germany), Hem-O-Lock clips (Weck, Teleflex, USA), and a 30° 5-mm optic (Karl Storz, Tuttlingen, GER), the interventions were executed like conventional laparoscopic transperitoneal procedures. OR time was mean 127 min [120, 153] for cirrhotic kidney nephrectomy group and mean 137 min [91, 185] in the radical nephrectomy group. Mean hemoglobin drop was 1.5 g/dl [1.2, 1.7] in benign cases and 2.4 [1.1, 4.9] in radial nephrectomies. All except one diabetic patient with wound infection had an uneventful follow-up without postoperative complications. The patients were discharged at postoperative day 5 [3, 29]. SITUS technique for simple and radical nephrectomy is an attractive alternative to conventional laparoscopy and single

    Full Text Available The Modular Prosthetic Limb (MPL was examined for its feasibility and usability as an advanced, dexterous upper extremity prosthesis with surface electromyography (sEMG control in with two individuals with below-elbow amputations. Compared to currently marketed prostheses, the MPL has a greater number of sequential and simultaneous degrees of motion, as well as wrist modularity, haptic feedback, and individual digit control. The MPL was successfully fit to a 33-year-old with a trans-radial amputation (TR01 and a 30-year-old with a wrist disarticulation amputation (TR02. To preserve anatomical limb length, we adjusted the powered degrees of freedom of wrist motion between users. Motor training began with practicing sEMG and pattern recognition control within the virtual integration environment (VIE. Prosthetic training sessions then allowed participants to complete a variety of activities of daily living with the MPL. Training and Motion Control Accuracy scores quantified their ability to consistently train and execute unique muscle-to-motion contraction patterns. Each user also completed one prosthetic functional metric—the Southampton Hand Assessment Procedure (SHAP for TR01 and the Jebsen-Taylor Hand Function Test (JHFT for TR02. Haptic feedback capabilities were integrated for TR01. TR01 achieved 95% accuracy at 84% of his VIE sessions. He demonstrated improved scores over a year of prosthetic training sessions, ultimately achieving simultaneous control of 13 of the 17 (76% attempted motions. His performance on the SHAP improved from baseline to final assessment with an increase in number of tasks achieved. TR01 also used vibrotactile sensors to successfully discriminate between hard and soft objects being grasped by the MPL hand. TR02 demonstrated 95% accuracy at 79% of his VIE sessions. He demonstrated improved scores over months of prosthetic training sessions, however there was a significant drop in scores initially following a mid

    Tenaerts, P; Madre, L; Landray, M


    The Clinical Trials Transformation Initiative reflects on 10 years of working to improve the quality and efficiency of clinical trials. This article highlights many of the Clinical Trials Transformation Initiative's accomplishments and offers examples of the impact that the Clinical Trials Transformation Initiative has had on the clinical trials enterprise. After conducting more than 25 projects and issuing recommendations for specific strategies to improve the design and execution of clinical trials, some common themes and lessons learned have emerged. Lessons include the importance of engaging many stakeholders, advanced planning to address critical issues, discontinuation of non-value added practices, and new opportunities presented by technology. Through its work, the Clinical Trials Transformation Initiative has also derived some operational best practices for conducting collaborative, multi-stakeholder projects covering project selection, project team dynamics and execution, and multi-stakeholder meetings and team discussions. Through these initiatives, the Clinical Trials Transformation Initiative has helped move the needle toward needed change in the clinical trials enterprise that has directly impacted stakeholders and patients alike.

    Shaikh, Rehan Moinuddin; Al-Yafi, A.; Malak, M.


    Objective was to evaluate the causes of cancellation rate of elective ocular surgeries in our tertiary care center and to analyze the need of Anesthesia Preoperative Medicine Clinic (APMC). We conducted a prospective study from January 21, 2006 till 30 June, 2006 at King Fahd Armed Forces Hospital, Jeddah, Saudi Arabia. The selected patients for the surgery have gone through pre operative investigations including CBC, Random blood sugar, coagulation profile, renal function tests, urea and electrolytes, IOL calculation and their medical condition assessment for the chronic disease. Study was conducted on 240 patients from whom 180 were adults and 60 were pediatrics. Out of 240 patients, 45 patients were cancelled in which 40 were adults and 5 were pediatric patients. In 45 patients 23 were male and 22 were female having a ratio of 1:1. Age was ranging from one year to 60+ an average of 58 years. Surgeries include was anterior segment, pediatric, retinal and oculoplastic. All these patients 45/240 were postponed at a percentage of 19%. The causes of cancellation were, improper control of diabetes, poor control of hypertension, cardiac problem, chest infection or influenza in children, overburden list and miscellaneous. All these patients were cancelled by anesthesia (28 patients), by surgeon (9 patients) and medical team (8 patients) in the ward as the patients were at high risk for the surgeries. So the reason in maximum patient was lack of anesthesia preoperative medicine clinic. The number of cancellation of ocular surgery can be minimized by proper assessment of the patient at anesthesia pre-operative medicine clinic (APMC). (author)

  2. Octogenarians' post-acute care use after cardiac valve surgery and recovery: clinical implications. (United States)

    Edmiston, Elizabeth; Dolansky, Mary A; Zullo, Melissa; Forman, Daniel E


    Octogenarians receiving cardiac valve surgery is increasing and recovery is challenging. Post-acute care (PAC) services assist with recovery, yet services provided in facilities do not provide adequate cardiac-focused care or long-term self-management support. The purpose of the paper was to report post-acute care discharge rates in octogenarians and propose clinical implications to improve PAC services. Using a 2003 Medicare Part A database, we studied post-acute care service use in octogenarians after cardiac valve surgery. We propose expansion of the Geriatric Cardiac Care model to include broader clinical therapy dynamics. The sample (n = 10,062) included patients over 80 years discharged from acute care following valve surgery. Post-acute care services were used by 68% of octagarians following cardiac valve surgery (1% intermediate rehabilitation, 35% skilled nursing facility, 32% home health). The large percentage of octagarians using PAC point to the importance of integrating geriatric cardiac care into post-acute services to optimize recovery outcomes. Copyright © 2017 Elsevier Inc.

    Postoperative atrial fibrillation (AF) is associated with increased morbidity, mortality, and resource utilization. Current prediction models for postoperative AF are based primarily on Western populations. In this study, we sought to develop a clinical prediction rule for postcardiac surgery AF for a multiethnic Asian population. Two thousand one hundred sixty-eight patients undergoing coronary artery bypass graft or valve surgery with cardiopulmonary bypass were prospectively enrolled in this observational study between August 2008 and July 2012 at Singapore's 2 national heart centers. Postoperative AF was defined as an irregularly irregular electrocardiogram rhythm without identifiable P wave after surgery and before hospital discharge that lasted more than an hour, or affected hemodynamics (ie, systolic blood pressure 120 minutes (OR, 1.92; 95% CI, 1.47-2.52, P Chinese ethnicity (Chinese versus Indian OR, 2.09; 95% CI, 1.28-3.41, P = 0.003) or Malay (Malay versus Indian OR, 2.43; 95% CI, 1.36-4.05, P = 0.002) to be independently associated with postoperative AF. The area under the receiver-operator characteristic curve of the model was 0.704 (95% CI, 0.674-0.734). Internal validation produced an area under the receiver-operator characteristic curve of 0.756 (95% CI, 0.690-0.821). Clinical risk factors for AF after cardiac surgery in an Asian population are similar to that reported from primarily Western populations, but specific ethnicity influences susceptibility.

    To compare pulmonary function, functional capacity, and clinical outcomes among conventional mechanical ventilation (CMV), early open-lung (EOL), and late open-lung (LOL) strategies after off-pump coronary artery bypass surgery (OPCAB). Prospective, randomized, and double-blinded study. Two hospitals of the Federal University of Sao Paulo, Brazil. Ninety-three patients undergoing elective first-time OPCAB. Patients were randomized into 3 groups: CMV (n=31); LOL (n=32) initiated upon intensive care unit (ICU) arrival; EOL (n = 30) initiated after intubation. Spirometry was performed at bedside preoperatively and on postoperative days (PODs) 1, 3, and 5. Partial pressure of arterial oxygen (PaO2) and pulmonary shunt fraction were evaluated presurgically and on POD 1; 6-minute walk test (6MWT) was performed presurgically and on POD 5. Both open-lung groups demonstrated higher forced vital capacity and forced expiratory volume in 1 second on PODs 1, 3 and 5 compared to the CMV group (pLOL groups were compared. Both open-lung strategies were able to promote higher pulmonary function preservation and greater recovery of functional capacity with better clinical outcomes after OPCAB. No difference in outcome was found when comparing initiation of OLS intraoperatively or after ICU arrival. Copyright © 2016 Elsevier Inc. All rights reserved.

    To determine the accuracy of post-operative MR in predicting residual disease in women with positive margins, emphasizing the size thresholds at which residual disease can be confidently identified. This IRB-approved HIPAA-compliant retrospective study included 175 patients with MR after positive margins following initial surgery for breast cancer. Two expert readers independently re-evaluated MR images for evidence of residual disease at the surgical cavity and multifocal/multicentric disease. All patients underwent definitive surgery and MR findings were correlated to histopathology. 139/175 (79.4%) patients had residual disease at surgery. Average overall sensitivity, specificity, PPV and NPV for residual disease at the surgical cavity were 73%, 72%, 91% and 45%, respectively. The readers identified 42/45 (93%, reader 1) and 43/45 (95%, reader 2) patients with residual invasive disease at the cavity of ≥5 mm and 22/22 (100%, both readers) patients with disease ≥10 mm. Average sensitivity, specificity, PPV and NPV for unknown multifocal/multicentric disease were 90%, 96%, 93% and 86%, respectively. Post-operative breast MR can accurately depict ≥5-mm residual disease at the surgical cavity and unsuspected multifocal/multicentric disease. These findings have the potential to lead to more appropriate selection of second surgical procedures in women with positive margins. (orig.)

  6. Uptake of an innovation in surgery: observations from the cluster-randomized Quality Initiative in Rectal Cancer trial. (United States)

    Simunovic, Marko; Coates, Angela; Smith, Andrew; Thabane, Lehana; Goldsmith, Charles H; Levine, Mark N


    Theory suggests the uptake of a medical innovation is influenced by how potential adopters perceive innovation characteristics and by characteristics of potential adopters. Innovation adoption is slow among the first 20% of individuals in a target group and then accelerates. The Quality Initiative in Rectal Cancer (QIRC) trial assessed if rectal cancer surgery outcomes could be improved through surgeon participation in the QIRC strategy. We tested if traditional uptake of innovation concepts applied to surgeons in the experimental arm of the trial. The QIRC strategy included workshops, access to opinion leaders, intraoperative demonstrations, postoperative questionnaires, and audit and feedback. For intraoperative demonstrations, a participating surgeon invited an outside surgeon to demonstrate optimal rectal surgery techniques. We used surgeon timing in a demonstration to differentiate early and late adopters of the QIRC strategy. Surgeons completed surveys on perceptions of the strategy and personal characteristics. Nineteen of 56 surgeons (34%) requested an operative demonstration on their first case of rectal surgery. Early and late adopters had similar perceptions of the QIRC strategy and similar characteristics. Late adopters were less likely than early adopters to perceive an advantage for the surgical techniques promoted by the trial (p = 0.023). Most traditional diffusion of innovation concepts did not apply to surgeons in the QIRC trial, with the exception of the importance of perceptions of comparative advantage.

    M Chokkalingam


    Full Text Available Background: Frozen shoulder is a condition characterized by pain and global restriction of movement with loss of external rotation. Cardiac surgery may predispose frozen shoulder as patients tend to immobilize their upper limbs after surgery. Objectives: The aim of this study is to analyze the clinical profile of patients presenting with symptoms of periarthritis shoulder and to determine the incidence of frozen shoulder among patients undergoing cardiac surgery as well as to find the factors associated with its development. Methods: It is a clinical observational study done in the Cardiology Department of Chettinad Hospital and Research Institute, Chennai, between August 2015 and May 2016, on 100 patients who underwent cardiac surgery and attended the follow-up session as an outpatient. Data were collected by face-to-face interview using a standardized questionnaire. Respondents presenting with pain and restricted movement of shoulder joint with positive limitation in lateral rotation, abduction, and medial rotation (LAM test were considered to have frozen shoulder. Each participant was followed up for 3 months postcardiac surgery. Results: The mean age of the study participants was 53.63 ± 13.03 years, and 65% were males. Of the 100 participants, 20 (20% developed frozen shoulder. Age (P < 0.01, diabetes mellitus (<0.01, hypertension (P < 0.001, type of surgery (P < 0.02, and regularity of physiotherapy follow-up (P < 0.01 had significant association with positive LAM test on univariate analysis. However, on multivariate logistic regression analysis, only hypertension and physiotherapy regularity were found to have a trend toward a significant independent association with the occurrence of frozen shoulder (P = 0.090 and 0.097, respectively. Conclusion: The present study shows that cardiac surgery increases the risk of developing frozen shoulder during the early postoperative period. Statistically significant correlation existed between

  8. Coronary surgery in patients with preexisting chronic atrial fibrillation: early and midterm clinical outcome. (United States)

    Rogers, Chris A; Angelini, Gianni D; Culliford, Lucy A; Capoun, Radek; Ascione, Raimondo


    The purpose of this study was to investigate the effect of preexisting atrial fibrillation on early and midterm clinical outcome in patients undergoing coronary surgery. All elective patients undergoing coronary artery bypass grafting surgery between April 1996 and September 2002 were investigated. Patients were grouped according to their preoperative cardiac rhythm: sinus rhythm (SR) or preexisting atrial fibrillation (AF). In-hospital clinical outcomes and 5-year patient survival and cardiac-related event-free survival were compared using regression methods to adjust for differences between the groups. In all, 5,092 patients were identified, 175 (3.4%) with a history of preexisting AF. These patients were older (median, 64 versus 68 years) and had higher Parsonnet scores (median, 4 versus 8) than the SR group. Previous myocardial infarction, cerebrovascular accident, hypertension, diabetes mellitus, renal impairment, peripheral vascular disease, ejection fraction less than 50%, previous surgery, congestive heart failure, and use of angiotensin-converting enzyme inhibitors were also more common in the AF group. There were 60 in-hospital deaths (1.2%), with no difference between the two groups (odds ratio 1.02, 95% CI: 0.35 to 2.94). Atrial fibrillation patients were more likely to need intraoperative inotropes (p = 0.044), postoperative intra-aortic balloon pump (p = 0.038), and were less likely to be discharged within 6 days (p = 0.017). The risk of death in the 5 years after surgery was higher in the AF group (relative risk 1.49, 95% CI: 1.06 to 2.08, p = 0.020). In the AF group, 109 (62.2%) patients were cardioverted spontaneously by surgery, but only 69 (39.4%) remained in SR until discharge. Longer-term rhythm follow-up data were available for 48 of these 69 patients, and only 36 remained in SR at a median follow-up of 1,483 days (interquartile range, 1,120 to 2,209). Spontaneous conversion to SR after surgery did not confer a midterm survival benefit (p = 0

    Bori, G; Gómez-Durán, E L; Combalia, A; Trilla, A; Prat, A; Bruguera, M; Arimany-Manso, J


    The specialist in orthopaedic and traumatological surgery, like any other doctor, is subject to the current legal provisions while exercising their profession. Mandatory training in the medical-legal aspects of health care is essential. Claims against doctors are a reality, and orthopaedic and traumatological surgery holds first place in terms of frequency of claims according to the data from the General Council of Official Colleges of Doctors of Catalonia. Professionals must be aware of the fundamental aspects of medical professional liability, as well as specific aspects, such as defensive medicine and clinical safety. The understanding of these medical-legal aspects in the routine clinical practice can help to pave the way towards a satisfactory and safe professional career. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2015 SECOT. Published by Elsevier Espana. All rights reserved.

  10. A Review of Current Clinical Applications of Three-Dimensional Printing in Spine Surgery. (United States)

    Cho, Woojin; Job, Alan Varkey; Chen, Jing; Baek, Jung Hwan


    Three-dimensional (3D) printing is a transformative technology with a potentially wide range of applications in the field of orthopaedic spine surgery. This article aims to review the current applications, limitations, and future developments of 3D printing technology in orthopaedic spine surgery. Current preoperative applications of 3D printing include construction of complex 3D anatomic models for improved visual understanding, preoperative surgical planning, and surgical simulations for resident education. Intraoperatively, 3D printers have been successfully used in surgical guidance systems and in the creation of patient specific implantable devices. Furthermore, 3D printing is revolutionizing the field of regenerative medicine and tissue engineering, allowing construction of biocompatible scaffolds suitable for cell growth and vasculature. Advances in printing technology and evidence of positive clinical outcomes are needed before there is an expansion of 3D printing applied to the clinical setting.

    The present study evaluated gingival recession 1 year following apical surgery of 70 maxillary anterior teeth (central and lateral incisors, canines, and first premolars). A visual assessment of the mid-facial aspect of the gingival level and of papillary heights of treated teeth was carried out...... using photographs taken at pre-treatment and 1-year follow-up appointments. In addition, changes in the gingival margin (GM) and clinical attachment levels (CAL) were calculated with the use of clinical measurements, that is, pre-treatment and 1-year follow-up pocket probing depth and level of gingival...... margin. Changes in GM and CAL were then correlated with patient-, tooth-, and surgery-related parameters. The following parameters were found to significantly influence changes in GM and CAL over time: gingival biotype (P gingival recession than thick biotype...

  12. Aggressive clinical approach to obesity improves metabolic and clinical outcomes and can prevent bariatric surgery: a single center experience. (United States)

    Cadegiani, Flavio A; Diniz, Gustavo C; Alves, Gabriella


    The number of bariatric procedures has exponentially increased in the past decade, as a result of the lack of successful clinical weight-loss interventions. The main reasons for the failure of clinical obesity management are: (1) anti-obesity medications are administered as monotherapies (or pre-combined drugs); (2) lack of combination between pharmacotherapy and non-pharmacological modalities; (3) short duration of pharmacotherapy for obesity; (4) lack of weight-loss maintenance strategies; (5) misunderstanding of the complex pathophysiology of obesity; and (6) underprescription of anti-obesity medications. We developed a protocol that can potentially overcome the drawbacks that may lead to the failure of clinical therapy for obesity. The aim of this study is therefore to report the clinical and metabolic effects of our proposed obesity-management protocol over a 2-year period, and to determine whether this more intensive approach to obesity management is feasible and a possible alternative to bariatric surgery in patients with moderate-to-severe obesity. This retrospective study involved 43 patients in whom bariatric surgery was indicated. Patients underwent an intensive anti-obesity protocol that included pharmacotherapy with multiple drugs; intense surveillance with monthly body analysis by air-displacement plethysmography, electrical bioimpedance, and 3D body scans; weekly psychotherapy; diet planning with a dietician every 2 months; and exercises at least 3 times a week with exercises prescribed by a personal trainer at least once a month. Body weight (BW), total weight excess (TWE), obesity class, body mass index, fat weight, muscle weight, waist circumference, and visceral fat were analyzed. Markers of lipid and glucose metabolism, liver function, and inflammation were also evaluated. Therapeutic success was defined as >20% BW loss or >50% decrease in TWE after 1 year. Significant improvements were observed in all clinical and metabolic parameters. Thirty

    Study Design A 3D-2D image registration algorithm, “LevelCheck,” was used to automatically label vertebrae in intraoperative mobile radiographs obtained during spine surgery. Accuracy, computation time, and potential failure modes were evaluated in a retrospective study of 20 patients. Objective To measurethe performance of the LevelCheck algorithm using clinical images acquired during spine surgery. Summary of Background Data In spine surgery, the potential for wrong level surgery is significant due to the difficulty of localizing target vertebrae based solely on visual impression, palpation, and fluoroscopy. To remedy this difficulty and reduce the risk of wrong-level surgery, our team introduced a program (dubbed LevelCheck) to automatically localize target vertebrae in mobile radiographs using robust 3D-2D image registration to preoperative CT. Methods Twenty consecutive patients undergoing thoracolumbar spine surgery, for whom both a preoperative CT scan and an intraoperative mobile radiograph were available, were retrospectively analyzed. A board-certified neuroradiologist determined the “true” vertebra levels in each radiograph. Registration of the preoperative CT to the intraoperative radiographwere calculated via LevelCheck, and projection distance errors were analyzed. Five hundred random initializations were performed for eachpatient, andalgorithm settings (viz., the number of robust multi-starts, ranging 50 to 200) were varied to evaluate the tradeoff between registration error and computation time. Failure mode analysis was performed by individually analyzing unsuccessful registrations (>5 mm distance error) observed with 50 multi-starts. Results At 200 robust multi-starts (computation time of ∼26 seconds), the registration accuracy was 100% across all 10,000 trials. As the number of multi-starts (and computation time) decreased, the registration remained fairly robust, down to 99.3% registration accuracy at 50 multi-starts (computation time

    The aim of the study was to investigate sociodemographic and clinical characteristics of people with gender dysphoria and differences of sociodemographic and clinical characteristics between female-to-male (FtM) and male-to-female (MtF) transsexual individuals. This study examined retrospectively sociodemographic and clinical characteristics of 139 cases with the diagnosis of gender dysphoria who were willing to undergo sex reassignment surgery and were referred to the Cerrahpaşa Medical Faculty between 2007-2013. Among 139 patients with gender dysphoria 102 were MtF (73,4%), and 37 patients were FtM (26,6%). In MtFs, rates of working in jobs which do not require high education level, unemployment, being a sex worker (p < 0,001), drug use (p = 0,017), and not having the health insurance (p < 0,001) were found to be significantly higher than FtMs. Rates of receiving psychotherapy for gender dysphoria (p = 0,001) and starting hormone therapy under the supervision of a doctor (p < 0,001) were significantly higher in FtMs, however higher rates of taking hormone therapy (p < 0,001) and undergoing surgery for sex reassignment (p < 0,001) were observed in the MtFs. There are significant differences both in sociodemographic characteristics and clinical characteristics between MtFs and FtMs. However further studies would be needed to identify underlying causes.

    Multicenter prospective pilot study. To evaluate if continuous physical activity monitoring by a personal electronic 3-dimensional accelerometer device is feasible and can provide objective data that correlates with patient-reported outcomes following spine surgery. Self-reported health-related quality-of-life (HRQOL) metrics are inherently limited by being very subjective, having a low frequency of data collection, and inconsistent follow-up. Inclusion criteria: adults (18+), thoracolumbar deformity or degenerative disease, and regular access to a computer with internet connection. Physical activity parameters included: number of daily steps, maximum hourly steps, and activity intensity. Patients completed the Oswestry Disability Index (ODI), the Short-Form Health Survey 36 (SF-36), and the Scoliosis Research Society-22r (SRS22) preoperatively and postoperatively at 6 weeks, 3 months, and 6 months. Thirty-two patients were enrolled, 8 (25%) withdrew, 1 (3.1%) died, and 1 (3.1%) did not end up undergoing surgery resulting in 22 (68.8%) available patients. Mean preoperative and postoperative step ranges were 1278±767 to 17,800±6464 and 891±587 to 12,655±7038, respectively. Eleven patients improved in mean total daily steps at the final postoperative month with 2 having significant improvements (P0.05) and 6 patients had significantly lower mean total daily steps at 6 months (PPhysical Component Summary, SRS Activity, SRS Appearance, SRS Mental, SRS Satisfaction, and SRS Total score at 6 months postoperative (PPhysical Component Summary were significantly correlated with preoperative average total daily steps (r=-0.61, P=0.0058 and r=0.60, P=0.0114, respectively).

    Full Text Available BACKGROUND Chronic venous insufficiency presents with a spectrum of clinical features ranging from pain or heaviness of affected limbs to non-healing ulcers over the lower limbs and usually require some form of surgical intervention, performing direct perforator vein division preferably by subfascial endoscopic perforator ligation surgery for perforator incompetence, as despite aggressive conservative therapy including compression, lifestyle modification and venotonic medications which are of high cost treatment with increased risk of increasing symptoms. MATERIALS AND METHODS A prospective longitudinal clinical study of 30 patients selected by systematic sampling method from November 2014 to September 2015 at our institution was conducted to determine the results of subfascial endoscopic perforator vein surgery (SEPS in perforator incompetence. RESULTS For venous clinical severity scoring pre operatively and after 3 weeks post-surgery, the mean for VCSS pre-operatively was 6.66 and a standard deviation of 2.399. The T value was calculated and was found to be 4.9321 and p value of 0.00001(p value less than 0.05 is significant. Similarly for the cases with active ulcer, the size assessment pre-operatively and post-SEPS was again analysed using student t test and the mean ulcer size prior to surgery was found to be 3.3 and standard deviation of 1.984. The T value was calculated and was found to be 1.789009 and a p value of 0.04 (p value less than 0.05 is significant. CONCLUSION Our study concluded that favourable and significant ulcer healing rate with improvement and reduction in clinical severity suggests that SEPS plays an important role in surgical management of advanced stages of venous insufficiency.

  17. Late Post-Conditioning with Sevoflurane after Cardiac Surgery--Are Surrogate Markers Associated with Clinical Outcome?

    Directory of Open Access Journals (Sweden)

    John M Bonvini

    Full Text Available In a recent randomized controlled trial our group has demonstrated in 102 patients that late post-conditioning with sevoflurane performed in the intensive care unit after surgery involving extracorporeal circulation reduced damage to cardiomyocytes exposed to ischemia reperfusion injury. On the first post-operative day the sevoflurane patients presented with lower troponin T values when compared with those undergoing propofol sedation. In order to assess possible clinical relevant long-term implications in patients enrolled in this study, we performed the current retrospective analysis focusing on cardiac and non-cardiac events during the first 6 months after surgery.All patients who had successfully completed the late post-conditioning trial were included into this follow-up. Our primary and secondary endpoints were the proportion of patients experiencing cardiac and non-cardiac events, respectively. Additionally, we were interested in assessing therapeutic interventions such as initiation or change of drug therapy, interventional treatment or surgery.Of 102 patients analyzed in the primary study 94 could be included in this follow-up. In the sevoflurane group (with 41 patients 16 (39% experienced one or several cardiac events within 6 months after cardiac surgery, in the propofol group (with 53 patients 19 (36%, p=0.75. Four patients (9% with sevoflurane vs. 7 (13% with propofol sedation had non-cardiac events (p=0.61. While a similar percentage of patients suffered from cardiac and/or non-cardiac events, only 12 patients in the sevoflurane group compared to 20 propofol patients needed a therapeutic intervention (OR: 0.24, 95% CI: 0.04-1.43, p=0.12. A similar result was found for hospital admissions: 2 patients in the sevoflurane group had to be re-admitted to the hospital compared to 8 in the propofol group (OR 0.23, 95% CI: 0.04-1.29, p=0.10.Sevoflurane does not seem to provide protection with regard to the occurrence of cardiac and non

    John, Hannah Eliza; Niumsawatt, Vachara; Whitaker, Iain S.


    Background Infrared thermography (IRT) has become an increasingly utilized adjunct to more expensive and/or invasive investigations in a range of surgical fields, no more so than in plastic surgery. The combination of functional assessment, flow characteristics and anatomical localization has led to increasing applications of this technology. This article aims to perform a systematic review of the clinical applications of IRT in plastic surgery. Methods A systematic literature search using the keywords ‘IRT’ and ‘dynamic infrared thermography (DIRT)’ has been accomplished. A total of 147 papers were extracted from various medical databases, of which 34 articles were subjected to a full read by two independent reviewers, to ensure the papers satisfied the inclusion and exclusion criteria. Studies focusing on the use of IRT in breast cancer diagnosis were excluded. Results A systematic review of 29 publications demonstrated the clinical applications of IRT in plastic surgery today. They include preoperative planning of perforators for free flaps, post operative monitoring of free flaps, use of IRT as an adjunct in burns depth analysis, in assessment of response to treatment in hemangioma and as a diagnostic test for cutaneous melanoma and carpal tunnel syndrome (CTS). Conclusions Modern infrared imaging technology with improved standardization protocols is now a credible, useful non-invasive tool in clinical practice. PMID:27047781

    To perform precise orthopaedic surgery, we have been developing a surgical method using a custom-made surgical device designed based on preoperative three-dimensional computer simulation. The purpose of this study was to investigate the preliminary results of its clinical application for corrective osteotomy of the upper extremity. Twenty patients with long bone deformities of the upper extremities (four cubitus varus deformities, nine malunited forearm fractures, six malunited distal radial fractures and one congenital deformity of the forearm) participated in this study. Three-dimensional computer models of the affected bone and the contralateral normal bone were constructed from computed tomography data. By comparing these models, the three-dimensional deformity axis and the accurate amount of deformity around it were quantified. Three-dimensional deformity correction was then simulated. A custom-made osteotomy template was designed and manufactured as a real plastic model aiming to reproduce the preoperative simulation in the actual operation. In the operation, we put the template on the bone surface, cut the bone through a slit on the template, and corrected the deformity as preoperatively simulated, followed by internal fixation. Radiographic and clinical evaluations were made in all cases before surgery and at the most recent follow-up. Corrective osteotomy was achieved as simulated in all cases. All patients had bone fusion within six months. Regarding the cubitus varus deformity, the average carrying angle and tilting angle were 5deg and 28deg after surgery. For malunited forearm fractures, angular deformities on radiographs were nearly nonexistent after surgery. All radiographic parameters in malunited distal radius fractures were normalized. The range of forearm rotation in cases of forearm malunion and that of wrist flexion-extension in cases of malunited distal radius improved after surgery. (author)

  20. Evaluation of Preemptive Use of Analgesia of The Skin, Before and After Lower Abdominal Surgery: A Prospective, Double-Blind, Randomized Clinical Trial

    Directory of Open Access Journals (Sweden)

    P Kashefi


    Full Text Available Background: Perioperative pain is prevalent and poorly treated. Apart from that it makes the recovery from surgery unpleasent, pain often remains as a residual side effect of surgery, even though the tissue healing is complete. An essential observation is that tissue injury and the resulting nociceptor barrage initiates a cascade of events that can indelibly alter pain perception. Preemptive analgesia is the concept of initiating analgesic therapy before the onset of the noxious stimulus so as to prevent the nociceptor barrage and its consequences. However, anticipated clinical potency of preemptive analgesia, though has firmly grounded in the neurobiology of pain, has not been yet realized. As data accumulates, it has become clear that clinical studies emulating those from the laboratory and designed around a relatively narrow definition of preemptive analgesia have been largely unsupportive of its use. Nevertheless, preemptive analgesic interventions that recognize the intensity, duration, and somatotopic extent of major surgery can help reduce perioperative pain and its longer-term sequelae. surgeons spend a lot of time treating the pain of lower abdominal surgery. Methods: A total number of 48 consecutive patients who were going to undergo elective lower abdominal surgery. Were randomly assigned in two groups of 24 each. In one group the patients received an injection of 0.5 % bupivacaine in the planned skin for incision just before lower abdominal surgery, and in the other group, they received an equal amount of 0.5% bupivacaine after the surgery had been done. Pain was objectified by a numerical visual pain score, in the 24 hours following the lower abdominal surgery. Results: There were no differences in postoperative pain scores on the visual analog scale (VAS: In groups 1and 2, VAS at hour 4 were 6.37±1.13 versus 6.29±1.19; At hour 8 were 5.54 ± 1.17 versus 5.37±1.09; and at hour 12 were 4.5 ± 1.31 versus 4.45 ± 1

    Body dysmorphic disorder (BDD) is a relative contraindication for facial plastic surgery, but formal screening is not common in practice. The prevalence of BDD in patients seeking facial plastic surgery is not well documented. To establish the prevalence of BDD across facial plastic and oculoplastic surgery practice settings, and estimate the ability of surgeons to screen for BDD. This multicenter prospective study recruited a cohort of 597 patients who presented to academic and private facial plastic and oculoplastic surgery practices from March 2015 to February 2016. All patients were screened for BDD using the Body Dysmorphic Disorder Questionnaire (BDDQ). After each clinical encounter, surgeons independently evaluated the likelihood that a participating patient had BDD. Validated instruments were used to assess satisfaction with facial appearance including the FACE-Q, Blepharoplasty Outcomes Evaluation (BOE), Facelift Outcomes Evaluation (FOE), Rhinoplasty Outcomes Evaluation (ROE), and Skin Rejuvenation Outcomes Evaluation (SROE). Across participating practices (9 surgeons, 3 sites), a total of 597 patients were screened for BDD: 342 patients from site 1 (mean [SD] age, 44.2 [16.5] years); 158 patients, site 2 (mean [SD] age, 46.0 [16.2] years), site 3, 97 patients (mean [SD] age, 56.3 [15.5] years). Overall, 58 patients [9.7%] screened positive for BDD by the BDDQ instrument, while only 16 of 402 patients [4.0%] were clinically suspected of BDD by surgeons. A higher percentage of patients presenting for cosmetic surgery (37 of 283 patients [13.1%]) compared with those presenting for reconstructive surgery (21 of 314 patients [6.7%]) screened positive on the BDDQ (odds ratio, 2.10; 95% CI, 1.20-3.68; P = .01). Surgeons were only able to correctly identify 2 of 43 patients (4.7%) who screened positive for BDD on the BDDQ, and the positive likelihood ratio was only 1.19 (95% CI, 0.28-5.07). Patients screening positive for BDD by the BDDQ had lower

  2. Clinical and Socio-demographic Predictors of Postoperative Vital Exhaustion in Patients after Cardiac Surgery (United States)

    Miller, Pamela S.; Evangelista, Lorraine S.; Giger, Joyce Newman; Dracup, Kathleen; Doering, Lynn V.


    Background Vital exhaustion, a psychological state characterized by extreme fatigue, is an independent predictor of future cardiac events. However, the attributes of vital exhaustion following coronary artery bypass (CABG) surgery are poorly understood. Objective The study objective was to assess correlates of vital exhaustion following CABG surgery. Methods In a descriptive, exploratory study, 42 patients who had CABG surgery were evaluated for exhaustion four to eight weeks post-hospital discharge. Demographic and clinical data were obtained from self-report and medical chart review. Results Of the total sample (mean age 67.9±12.5, 90% male, 70% Caucasian, 3.12±1.3 grafts), approximately 41% reported exhaustion. When compared to their exhausted post-CABG counterpart, non-exhausted post-CABG patients had a significantly higher frequency of preoperative insulin use. Exhausted patients were significantly more likely to have higher left ventricular ejection fraction ([LVEF], OR 1.07, p=0.04), and elevated hemoglobin (OR 2.98, p=0.03) and eosinophils (OR 1.02, p=0.02) than those who were not exhausted. Conclusion Clinicians should evaluate all patients for exhaustion post-CABG surgery; patients with elevated LVEF, hemoglobin, and eosinophil levels warrant increased scrutiny. PMID:23453010

    Smith, Stephen Ridley; Draganic, Brian; Pockney, Peter; Holz, Phillip; Holmes, Ryan; Mcmanus, Brendan; Carroll, Rosemary


    Adequate postoperative analgesia is essential for recovery following colorectal surgery. Transversus abdominis plane (TAP) blocks have been found to be beneficial in improving pain following a variety of abdominal operations. The objective of this study was to determine if TAP blocks are useful in improving postoperative recovery following laparoscopic colorectal surgery. A prospective double-blind randomized clinical trial, involving 226 consecutive patients having laparoscopic colorectal surgery, was performed by a university colorectal surgical department. Patients were randomized to either TAP blockade using ultrasound guidance, or control, with the primary outcome being postoperative pain, as measured by analgesic consumption. Secondary outcomes assessed were pain visual analogue score (VAS), respiratory function, time to return of gut function, length of hospital stay, postoperative complications, and patient satisfaction. A total of 142 patients were followed up to trial completion (74 controls, 68 interventions). Patients were well matched with regard to demographics. No complications occurred as a result of the intervention of TAP blockade. There was no difference between groups with regards to analgesic consumption (161 mEq morphine control vs 175 mEq morphine TAP; p = 0.596). There was no difference between the two groups with regards to the secondary outcomes of daily VAS, respiratory outcome, time to return of gut function, length of hospital stay, postoperative complications, and patient satisfaction. We conclude that TAP blockade appears to be a safe intervention but confers no specific advantage following laparoscopic colorectal surgery.

    This is a prospective randomized and controlled study, approved by the local ethical committee of Saarland (Germany). The aim of the current study was to analyze segmental motion following artificial disc replacement using disc prosthesis over 1 year. A second aim was to compare both segmental motion as well as clinical result to the current gold standard (anterior cervical discectomy and fusion [ACDF]). ACDF may be considered to be the gold standard for treatment of symptomatic degenerative disc disease within the cervical spine. However, fusion may result in progressive degeneration of the adjacent segments. Therefore, disc arthroplasty has been introduced. Among these, artificial disc replacement seems to be promising. However, segmental motion should be preserved. This, again, is very difficult to judge and has not yet been proven. A total of 49 patients with cervical disc herniation were enrolled and assigned to either study group (receiving a disc prosthesis) or control group (receiving ACDF, using a cage with bone graft and an anterior plate). Roentgen stereometric analysis (RSA) was used to quantify intervertebral motion immediately as well as 3, 6, 12, 24, and 52 weeks after surgery. Also, clinical results were judged using visual analog scale and neuro-examination at even RSA follow-up. Cervical spine segmental motion decreased over time in the presence of disc prosthesis or fusion device. However, the loss segmental motion is significantly higher in the fusion group, when looked at 3, 6, 12, 24, and 52 weeks after surgery. We observed significant pain reduction in neck and arm after surgery, without significant difference between both groups. Cervical spine disc prosthesis remains cervical spine segmental motion within the first 1 year after surgery. The clinical results are the same when compared with the early results following ACDF.

    Full text: The objective of this paper is to evaluate the uses of different human bone tissue allografts in bucomaxillary surgery between 2005 and 2007. Presentation of our experience using single freeze dried bone allografts and associated to bovine collagen membranes (commercial registered). Twenty patients were treated with cortical struts, cancellous chips, morsellized and morsellized demineralized bone. All the grafts were processed at the INDT multi tissue bank from cardiac arrest and brain death cadaveric donors. All the tissues were radiosterilized by Gamma radiation. Bone allografts were used: 1) to optimize bone support increasing maxillar or mandible bone before implant surgery. 2) in dehiscences and fissures during the implant surgery. 3) to stimulate bone regeneration in alveolar cavity, post-apicectomies, and cystectomies as well as for bone defects. The patients were periodically evaluated using standardized protocols. All the cases were successful showing clinic and radiologically osseointegration after 6 and 12 months. Results were evaluated considering surgical technique and patients bucomaxillary rehabilitation. Clinical uses of bone allografts confirm in our experience, as scientific literature outcomes shows, are useful in patients that refuses autografts ablation. (Author)

  9. Clinical and endocrinological evaluation of 16 acromegalic patients treated by transsphenoidal surgery. (United States)

    Leavens, M E; Samaan, N A; Jesse, R H; Byers, R M


    Sixteen patients with acromegaly treated with transsphenoidal pituitary surgery were evaluated with the measurement of serum human growth hormone (HGH) before and after intravenous stimulation with thyrotropin-releasing hormone (TRH). Fourteen of these patients showed a significant rise of serum HGH after TRH stimulation before surgery. After surgery, 12 patients with Grade 2 noninvasive adenomas had normal fasting serum HGH levels which did not stimulate with TRH. Two of these patients showed high serum HGH levels both at fasting and after TRH stimulation and required a second operation to remove residual adenoma within the sella before adequate lowering of HGH was achieved. Evidence of recurrent adenoma has not occurred clinically or biochemically in this group of 12 patients followed for an average of 24 months (2 to 60 months). The results were unsatisfactory in four of these 16 patients. One patient who has a postoperative HGH of 9 ng/ml which still stimulates with TRH has made clinical improvement, but must have residual adenoma in the sella or invasive adenoma in the dura and tumor capsule. Additional treatment with irradiation has been given. Failure to achieve satisfactory results in the other three patients was attributed to the presence of locally invasive adenoma; one in the sphenoid sinus, and the other two possibly as a consequence of previous operative procedures.

  10. Making a difference: using the safe surgery checklist to initiate continuing education for perioperative nurses in low-income settings. (United States)

    Leifso, Genelle


    The WHO Safe Surgery Checklist (2008) patient safety focus and communication prompts are widely accepted. In many low-income regions (as defined by the World Bank and accepted by the World Health Organization) perioperative nurses have little or no formal training; continuing and in-service education are virtually unknown; nor does an articulated "culture of safety" exist. In 2009 the Canadian Network for International Surgery (CNIS) piloted a two-day perioperative nursing course, in Addis Ababa, Ethiopia, using lectures, case studies, skills sessions, and role-play exercises based on the SSSL Checklist outline and protocols. Canadian instructors (who are certified after taking the Canadian Network for International Surgery-sponsored Instructor's Course) have since returned and taught at additional sites in Ethiopia and Uganda. Course participants now include perioperative nurses, anaesthetists, and junior surgical residents--mirroring the interdisciplinary teamwork that is crucial to safe perioperative patient care. The course's facilitated discussions focus on workplace and practice issues in order to allow for appropriate evaluation and planning of future educational initiatives. Participants complete pre- and post-course questionnaires, which evaluate baseline and post-course knowledge, and further follow-up is completed four months after course completion. This article explains the need for aiding in the expansion of perioperative nursing knowledge and skill in low-income settings and provides the author's personal perspective and experience in responding to this need. Her experience as facilitator in a pilot project and subsequent course development described. The objective is to discuss ways that other perioperative nurses can work to make a positive difference on professional practice and patient care in low-income regions.

  11. A national evaluation of clinical and economic outcomes in open versus laparoscopic colorectal surgery. (United States)

    Keller, Deborah S; Delaney, Conor P; Hashemi, Lobat; Haas, Eric M


    Surgical value is based on optimizing clinical and financial outcomes. The clinical benefits of laparoscopic surgery are well established; however, many patients are still not offered a laparoscopic procedure. Our objective was to compare the modern clinical and financial outcomes of laparoscopic and open colorectal surgery. The Premier Perspective database identified patients undergoing elective colorectal resections from January 1, 2013 to December 31, 2013. Cases were stratified by operative approach into laparoscopic and open cohorts. Groups were controlled on all demographics, diagnosis, procedural, hospital characteristics, surgeon volume, and surgeon specialty and then compared for clinical and financial outcomes. The main outcome measures were length of stay (LOS), complications, readmission rates, and cost by surgical approach. A total of 6343 patients were matched and analyzed in each cohort. The most common diagnosis was diverticulitis (p = 0.0835) and the most common procedure a sigmoidectomy (p = 0.0962). The LOS was significantly shorter in laparoscopic compared to open (mean 5.78 vs. 7.80 days, p value to both patient and provider.

    To understand statewide variation in preoperative cardiology consultation prior to major vascular surgery and to determine whether consultation was associated with differences in perioperative myocardial infarction (poMI). Medical consultation prior to major vascular surgery is obtained to reduce perioperative risk. Despite perceived benefit of preoperative consultation, evidence is lacking specifically for major vascular surgery on the effect of preoperative cardiac consultation. Patient and clinical data were obtained from a statewide vascular surgery registry between January 2012 and December 2014. Patients were risk stratified by revised cardiac risk index category and compared poMI between patients who did or did not receive a preoperative cardiology consultation. We then used logistic regression analysis to compare the rate of poMI across hospitals grouped into quartiles by rate of preoperative cardiology consultation. Our study population comprised 5191 patients undergoing open peripheral arterial bypass (n = 3037), open abdominal aortic aneurysm repair (n = 332), or endovascular aneurysm repair (n = 1822) at 29 hospitals. At the patient level, after risk-stratification by revised cardiac risk index category, there was no association between cardiac consultation and poMI. At the hospital level, preoperative cardiac consultation varied substantially between hospitals (6.9%-87.5%, P 66%) had a reduction in poMI (OR, 0.52; confidence interval: 0.28-0.98; P cardiology consultation for vascular surgery varies greatly between institutions, and does not appear to impact poMI at the patient level. However, reduction of poMI was noted at the hospitals with the highest rate of preoperative cardiology consultation as well as a variety of medical services, suggesting that other hospital culture effects play a role.

  13. Triclosan-coated sutures reduce wound infections after spinal surgery: a retrospective, nonrandomized, clinical study. (United States)

    Ueno, Masaki; Saito, Wataru; Yamagata, Megumu; Imura, Takayuki; Inoue, Gen; Nakazawa, Toshiyuki; Takahira, Naonobu; Uchida, Kentaro; Fukahori, Nobuko; Shimomura, Kiyomi; Takaso, Masashi


    Surgical site infection (SSI) is a serious postoperative complication. The incidence of SSIs is lower in clean orthopedic surgery than in other fields, but it is higher after spinal surgery, reaching 4.15% in high-risk patients. Several studies reported that triclosan-coated polyglactin 910 sutures (Vicryl Plus; Ethicon, Inc., Somerville, NJ, USA) significantly reduced the infection rate in the general surgical, neurosurgical, and thoracic surgical fields. However, there have been no studies on the effects of such coated sutures on the incidence of SSIs in orthopedics. To compare the incidence of wound infections after spinal surgery using triclosan-coated suture materials with that of noncoated ones. A retrospective, nonrandomized, and clinical study. From May 2010 to April 2012, 405 patients underwent a spinal surgical procedure in the Department of Orthopedic Surgery of two university hospitals. The primary outcome was the number of wound infections and dehiscences. Two hundred five patients had a conventional wound closure with polyglactin 910 suture (Vicryl) between May 2010 and April 2011 (Time Period 1 [TP1]), and 200 patients underwent wound closure with triclosan-coated polyglactin 910 suture (Vicryl Plus) between May 2011 and April 2012 (TP2). Statistical comparisons of wound infections, dehiscence, and risk factors for poor wound healing or infection were performed. None of the authors has any conflict of interest associated with this study. There were two cases of wound dehiscence in TP1 and one in TP2 (p=.509). Using noncoated sutures in TP1, eight patients (3.90%) had wound infections, whereas one patient (0.50%) had wound infections in TP2 (using triclosan-coated sutures); the difference was significant (p=.020). The use of triclosan-coated polyglactin 910 sutures instead of polyglactin 910 sutures may reduce the number of wound infections after spinal surgery. Copyright © 2015 Elsevier Inc.

  14. Antibiotics in periodontal surgeries: A prospective randomised cross over clinical trial

    Directory of Open Access Journals (Sweden)

    Sheetal Oswal


    Full Text Available Aims and Objectives: (1 To evaluate the need of antibiotics in periodontal surgeries in reducing postsurgical infections and explore if antibiotics have any key role in reducing or eliminating inflammatory complications. (2 To establish the incidence of postoperative infections in relation to type of surgery and determine those factors, which may affect infection rates. Materials and Methods: A prospective randomized double-blind cross over clinical study was carried out for a period of 1-year with predefined inclusion and exclusion criteria. All the patients included in the study for any periodontal surgery were randomly divided into three categories: Group A (prophylactic, Group B (therapeutic, and Group C (no antibiotics. Patients were followed up for 1-week after surgery on the day of suture removal and were evaluated for pain, swelling, fever, infection, delayed wound healing and any other significant findings. Appropriate statistical analysis was carried out to evaluate the objectives and P < 0.05 was considered as statistically significant. Results: No infection was reported in any of 90 sites. Patients reported less pain and postoperative discomfort when prophylactic antibiotics were given. However, there were no statistical significant differences between the three groups. Summary and Conclusion: There was no postoperative infection reported in all the 90 sites operated in this study. The prevalence of postoperative infections following periodontal surgery is <1% and this low risk does not justify the routine use of systemic antimicrobials just to prevent infections. Use of prophylactic antibiotics may have role in prevention of inflammatory complication, but again not infection.

  15. The differential impact of plastic surgery subspecialties on the financial performance of an academic clinical practice. (United States)

    Chao, Albert H; Khansa, Ibrahim; Kaiser, Christopher; Bell, Julian; Miller, Michael J


    In an academic center, plastic surgery provides multiple important and distinct services. Limited data exist on how each service affects a department clinically and financially. All new patient consultations and surgical cases between 2004 and 2012 were reviewed. Conversion rates from consultation to surgery and relative value units were calculated. Professional and facility revenues, costs, and net income were ascertained. These measures were compared between different subspecialties. A total of 12,020 new patient consultations and 5741 surgical cases were reviewed. Total growth in consultations was greatest for breast reconstruction (396.8 percent), followed by aesthetic (83.8 percent), oncology (12.9 percent), general (-16.9 percent), and burn/trauma (-75.0 percent). The conversion rate from consultation to surgery was highest in breast reconstruction (57.0 ± 3.1 percent) and oncology (56.9 ± 6.6 percent), followed by burn/trauma (47.0 ± 6.8 percent), general (46.1 ± 3.5 percent), and aesthetic (37.0 ± 4.8 percent). Total growth in professional net income was greatest for breast reconstruction (1241.4 percent), followed by oncology (378.4 percent), general (159.7 percent), aesthetic (130.5 percent), and burn/trauma (-20.9 percent). Total growth in facility net income was greatest for breast reconstruction (7619.5 percent), followed by oncology (2648.0 percent), aesthetic (432.3 percent), general (283.3 percent), and burn/trauma (108.7 percent). Breast reconstruction exhibited the greatest growth in consultations, and oncologic consultations demonstrated the highest consultation-to-surgery conversion rate. The higher consultation volume and conversion rate associated with breast reconstruction resulted in greater financial gains for both the department and the hospital. These findings may be of utility in the development of academic plastic surgery programs.

    Multicenter retrospective study. To investigate the risk of symptomatic recurrent laryngeal nerve palsy (RLNP) following cervical spine surgery, to examine risk factors for its development, and to report its treatment and outcomes. A multicenter study from 21 high-volume surgical centers from the AOSpine North America Clinical Research Network was performed. Each center screened for rare complications following cervical spine surgery, including RLNP. Patients were included if they underwent cervical spine surgery (levels from C2 to C7) between January 1, 2005 and December 31, 2011. Data were analyzed with regard to complication treatment and outcome. Cases were compared to a control group from the AOSpine CSM and CSM-I studies. Three centers reported 19 cases of RLNP from a cohort of 1345 patients. The reported incidence of RLNP ranged from 0.6% to 2.9% between these 3 centers. Fifteen patients (79%) in the RLNP group were approached from the left side. Ten patients (52.6%) required treatment for RLNP-6 required medical therapy (steroids), 1 interventional treatment (injection laryngoplasty), and 3 conservative therapy (speech therapy). When examining outcomes, 73.7% (14/19) of cases resolved completely, 15.8% (3/19) resolved with residual effects, and in 10.5% (2/19) of cases this could not be determined. In this multicenter study examining rare complications following cervical spine surgery, the risk of RLNP after cervical spine surgery ranged from 0.6% to 2.9% between centers. Though rare, it was found that 16% of patients may experience partial resolution with residual effects, and 74% resolve completely.

  18. Prospective, randomized, multi-institutional clinical trial of a silver alginate dressing to reduce lower extremity vascular surgery wound complications. (United States)

    Ozaki, C Keith; Hamdan, Allen D; Barshes, Neal R; Wyers, Mark; Hevelone, Nathanael D; Belkin, Michael; Nguyen, Louis L


    Wound complications negatively affect outcomes of lower extremity arterial reconstruction. By way of an investigator initiated clinical trial, we tested the hypothesis that a silver-eluting alginate topical surgical dressing would lower wound complication rates in patients undergoing open arterial procedures in the lower extremity. The study block-randomized 500 patients at three institutions to standard gauze or silver alginate dressings placed over incisions after leg arterial surgery. This original operating room dressing remained until gross soiling, clinical need to remove, or postoperative day 3, whichever was first. Subsequent care was at the provider's discretion. The primary end point was 30-day wound complication incidence generally based on National Surgical Quality Improvement Program guidelines. Demographic, clinical, quality of life, and economic end points were also collected. Wound closure was at the surgeon's discretion. Participants (72% male) were 84% white, 45% were diabetic, 41% had critical limb ischemia, and 32% had claudication (with aneurysm, bypass revision, other). The overall 30-day wound complication incidence was 30%, with superficial surgical site infection as the most common. In intent-to-treat analysis, silver alginate had no effect on wound complications. Multivariable analysis showed that Coumadin (Bristol-Myers Squibb, Princeton, NJ; odds ratio [OR], 1.72; 95% confidence interval [CI], 1.03-2.87; P = .03), higher body mass index (OR, 1.05; 95% CI, 1.01-1.09; P = .01), and the use of no conduit/material (OR, 0.12; 95% CI, 0.82-3.59; P silver-eluting alginate dressing showed no effect on the incidence of wound complications.

    Yamamoto, Kazuhito


    This study was designed to determine the clinical usefulness of radioimmunoguided surgery (RIGS) using the human-mouse chimeric Fab monoclonal antibody A7 (chA7Fab) for colorectal cancer patients. Whole murine monoclonal antibody A7 (whole A7) and chA7Fab were labelled with 125 I and 131 I, and their biodistributions were investigated experimentally and clinically. Radioactivities of the antibodies in the tissues were measured by a portable gamma detecting probe (GDP) purchased from Neoprobe Corp.. Of the four labelled antibodies used in a mouse model, 125 I-chA7Fab revealed the highest tumor/surrounding tissue ratio and all values were greater than 2.0. All tumor/surrounding tissue ratios of 131 I-chA7Fab were greater than 1.5, but the values were lower than those of 125 I-chA7Fab. Due to the limited clinical use of 125 I in Japan, 131 I was used as a radio-tracer for chA7Fab in the clinical trial. RIGS using 131 I-chA7Fab was performed on ten colorectal cancer patients. Tumor localization was intraoperatively determined in four of ten patients using the GDP. Liver metastasis and lymph node metastasis were identified in two patients and one patient, respectively. The GDP revealed tumor/surrounding tissue ratios of 1.5 or greater in eight of the ten resected tumors. Although radioimmunoguided surgery using chA7Fab is a promising tool to intraoperatively determine the tumor localization of colorectal cancer, 125 I and not 131 I should be used as a tracer for radioimmunoguided surgery to increase the accuracy of chA7Fab.

    Sarah M. Westberg


    Full Text Available Objectives: To develop and deliver an effective pharmacist-led educational initiative to clinic staff to advance medication reconciliation in the electronic medical record of an outpatient internal medicine clinic. Methods: An educational initiative designed to improve the ability of nursing staff in medication reconciliation was launched in the outpatient internal medicine clinic of a regional healthcare system. The education was provided by the pharmacist to clinic nursing staff, including registered nurses, licensed practical nurses, and certified medical assistants. The impact of this training was measured through pre-initiation and post-implementation surveys, competency assessments and an audit. Results: The educational initiative was successfully designed and delivered to clinic nursing staff. Assessment of the initiative found that all nursing staff completing competency assessments successfully passed. Pre-initiation- and post-implementation- survey responses on the self-assessed ability to gather and document accurate medication lists did not show significant changes. Informal observations in the clinic indicated that this initiative changed the culture of the clinic, creating increased awareness of the importance of accurate medications and increased emphasis on medication reconciliation. Conclusions: The expertise of pharmacists can be utilized to educate nursing staff on the skills and abilities necessary to gather and document accurate medication lists. This study did not find measurable changes in the accuracy of medication lists in this clinic. Future research is needed to determine the best methods to train health professionals in medication reconciliation to ensure accurate medication lists in the outpatient setting.

  1. An evidence-based clinical guideline for the use of antithrombotic therapies in spine surgery. (United States)

    Bono, Christopher M; Watters, William C; Heggeness, Michael H; Resnick, Daniel K; Shaffer, William O; Baisden, Jamie; Ben-Galim, Peleg; Easa, John E; Fernand, Robert; Lamer, Tim; Matz, Paul G; Mendel, Richard C; Patel, Rajeev K; Reitman, Charles A; Toton, John F


    The objective of the North American Spine Society (NASS) Evidence-Based Clinical Guideline on antithrombotic therapies in spine surgery was to provide evidence-based recommendations to address key clinical questions surrounding the use of antithrombotic therapies in spine surgery. The guideline is intended to address these questions based on the highest quality clinical literature available on this subject as of February 2008. The goal of the guideline recommendations was to assist in delivering optimum, efficacious treatment with the goal of preventing thromboembolic events. To provide an evidence-based, educational tool to assist spine surgeons in minimizing the risk of deep venous thrombosis (DVT) and pulmonary embolism (PE). Systematic review and evidence-based clinical guideline. This report is from the Antithrombotic Therapies Work Group of the NASS Evidence-Based Guideline Development Committee. The work group was composed of multidisciplinary spine care specialists, all of whom were trained in the principles of evidence-based analysis. Each member of the group was involved in formatting a series of clinical questions to be addressed by the group. The final questions agreed on by the group are the subject of this report. A literature search addressing each question and using a specific search protocol was performed on English language references found in MEDLINE, EMBASE (Drugs and Pharmacology), and four additional, evidence-based databases. The relevant literature was then independently rated by at least three reviewers using the NASS-adopted standardized levels of evidence. An evidentiary table was created for each of the questions. Final grades of recommendation for the answers to each clinical question were arrived at via Web casts among members of the work group using standardized grades of recommendation. When Level I to IV evidence was insufficient to support a recommendation to answer a specific clinical question, expert consensus was arrived at by

  2. Current Evidence for Clinical Efficacy of Platelet Rich Plasma in Aesthetic Surgery: A Systematic Review. (United States)

    Frautschi, Russell S; Hashem, Ahmed M; Halasa, Brianna; Cakmakoglu, Cagri; Zins, James E


    Platelet rich plasma (PRP) has attracted attention in a number of surgical fields due to a wide variety of potential clinical benefits. Yet PRP has not gained wide popularity in aesthetic surgery as a result of uncertainty surrounding objective clinical evidence. We aim to describe the current applications, define preparation and activation, explore effectiveness, and propose a classification system to facilitate comparisons across studies. A comprehensive review of the literature regarding the use of platelet rich plasma in aesthetic surgery was performed. Data gathered included: PRP application, study type, subject number, centrifugation, anticoagulation, activation, PRP composition, and outcomes. Thirty-eight reports were identified. Applications included injection into aging skin (29%), scalp alopecia (26%), lipofilling (21%), fractional laser (13%), and facial surgery (11%). The majority of studies (53%) were case series without controls. Leucocytes were sparsely defined (32%). The concentration of injected and/or baseline platelets was rarely clarified (18%). The mechanism of activation was described in 27 studies (71%), while anticoagulation was uncommonly elucidated (47%). While most studies (95%) claim effectiveness, objective measures were only utilized in 17 studies (47%). Current studies produce context-dependent results with a lack of consistent reporting of PRP preparation, composition, and activation in aesthetic applications, making meaningful meta-analysis unrealistic. Thus the method of PRP preparation warrants increased attention. We recommend a set of descriptors, FIT PAAW (described below), to produce scientifically grounded conclusions, facilitating a clearer understanding of the situations in which PRP is effective. 4 © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

  3. Preoperative neutrophil response as a predictive marker of clinical outcome following open heart surgery and the impact of leukocyte filtration.

    LENUS (Irish Health Repository)

    Soo, Alan W


    Open heart surgery is associated with a massive systemic inflammatory response. Neutrophils, are the main mediator of this response. We hypothesised that the degree of neutrophil activation and inflammatory response to open heart surgery varies individually and correlates with clinical outcome. The aim of this study was to determine if individual clinical outcome can be predicted preoperatively through assessment of in-vitro stimulated neutrophil responses. Following that, the effects of neutrophil depletion through leukocyte filters are examined.

  4. Giant cell tumor of the bone: aggressive case initially treated with denosumab and intralesional surgery

    Energy Technology Data Exchange (ETDEWEB)

    Von Borstel, Donald; Strle, Nicholas A. [Oklahoma State University Medical Center, Department of Radiology, Tulsa, OK (United States); Taguibao, Roberto A. [University of California, Irvine, UCI Medical Center, Department of Pathology, Orange, CA (United States); Burns, Joseph E. [University of California, Irvine, UCI Medical Center, Department of Radiological Sciences, Orange, CA (United States)


    Giant cell tumor of the bone (GCTB) is a locally aggressive benign tumor, which has historically been treated with wide surgical excision. We report a case of a 29-year-old male with histology-proven GCTB of the distal ulna. The initial imaging study was a contrast-enhanced magnetic resonance imaging (MRI) examination of the left wrist, which was from an outside facility performed before presenting to our institution. On the initial MRI, the lesion had homogenous T2-hyperintense and T1-hypointense signal with expansive remodeling of the osseous contour. A radiographic study performed upon presentation to our institution 1 month later showed progression of the lesion with atypical imaging characteristics. After confirming the diagnosis, denosumab therapy was implemented allowing for reconstitution of bone and intralesional treatment. The patient was treated with five doses of denosumab over the duration of 7 weeks. Therapeutic changes of the GCTB were evaluated by radiography and a post-treatment MRI. This MRI was interpreted as suspicious for worsening disease due to the imaging appearance of intralesional signal heterogeneity, increased perilesional fluid-like signal, and circumferential cortical irregularity. However, on subsequent intralesional curettage and bone autografting 6 weeks later, no giant cells were seen on the specimen. Thus, the appearance on the MRI, rather than representing a manifestation of lesion aggressiveness or a non-responding tumor, conversely represented the imaging appearance of a positive response to denosumab therapy. On follow-up evaluation, 5 months after intralesional treatment, the patient had recurrent disease and is now scheduled for wide-excision with joint prosthesis. (orig.)

  5. Clinical trial of modified ankylos implants for extraoral use in cranio- and maxillofacial surgery. (United States)

    Schlegel, Karl Andreas; Schultze-Mosgau, Stefan; Eitner, Stefan; Wiltfang, Joerg; Rupprecht, Stephan


    Epithetic solutions in the maxillofacial region are indicated if plastic surgery reconstruction is not a valid option for an extensive defect. The purpose of this study was to examine whether the extraoral implants used provided sufficient retention to be used as anchoring aids. Between November 1999 and September 2002, 33 identical modified Ankylos implants for extraoral anchorage were placed in 10 patients for the fixation of various epitheses in the midfacial (eye, nose) and ear regions in the course of a clinical trial. Over a follow-up period of 2 to 34 months, all implants remained osseointegrated (as confirmed radiographically), and the implants and epithetic restorations were clinically stable. The results demonstrated that the lasting retention of maxillofacial epitheses provided by implants assures patients that their epitheses are securely fixed. The demonstrated extraoral implant system not only achieved sufficient osseointegration but also showed good clinical handling and easy fixation possibilities for epithetic anchorage.

  6. Clinical efficacy of dexmedetomidine in the diminution of fentanyl dosage in pediatric cardiac surgery. (United States)

    Sun, Yingying; Ye, Hongwu; Xia, Yin; Li, Yuanhai; Yuan, Xianren; Wang, Xing


    This study aims to explore the clinical efficacy of dexmedetomidine (DEX) in the diminution of fentanyl dosage in pediatric cardiac surgery based on some clinical and biochemical parameters. Fifty pediatric patients (American Society of Anesthesiologists II), 1-6 years old, were randomly allocated into two groups: group F (control group), in which patients received normal saline and high dosage of fentanyl (30 μg/kg), and group D, in which patients were given DEX and low dosage of fentanyl (15 μg/kg). Some hemodynamic and clinical parameters of the two groups were recorded. Furthermore, stress hormone (serum cortisol, norepinephrine, blood glucose) levels and cytokine (interleukin 6, tumor necrosis factor alpha) levels in the two groups were compared with each other. Stress hormone levels, cytokine levels, hemodynamic parameters and the consumption of sevoflurane did not differ between the two groups. Meanwhile, the extubation time was significantly shorter in Group D than F (Pfentanyl supplemented with DEX almost had the same anesthesia effects and inflammation extent compared with high dose of fentanyl, which suggested that infusion DEX might decrease fentanyl consumption in pediatric cardiac surgery.

  7. Mohs micrographic surgery for the treatment of hidradenocarcinoma: the Mayo Clinic experience from 1993 to 2013. (United States)

    Tolkachjov, Stanislav N; Hocker, Thomas L; Hochwalt, Phillip C; Camilleri, Michael J; Arpey, Christopher J; Brewer, Jerry D; Otley, Clark C; Roenigk, Randall K; Baum, Christian L


    Hidradenocarcinoma (HAC) is a rare malignant adnexal neoplasm with reported metastatic potential and undefined optimal treatment. To review clinical characteristics and outcomes of patients with HAC treated with Mohs micrographic surgery (MMS). The authors performed a retrospective chart review of patients with HAC treated by MMS at Mayo Clinic from 1993 to 2013, recording patient demographics, tumor characteristics, MMS stages to clearance, follow-up, recurrence, metastasis, and mortality. Ten patients underwent MMS for HAC more than 20 years. The average age was 62.8 years, with 6 females and 4 males. Occipital scalp was the most common location (40%), followed by extremities (30%) and face (20%). In 5 of 7 cases (71%), "cyst" was the working clinical diagnosis. The average preoperative lesion area was 3.18 cm, with an average of 1.5 MMS stages required for clearance. Mean postoperative follow-up was 7 years (range, 5-205 months). No tumors treated with MMS recurred, metastasized, or led to disease-related mortality. Mohs micrographic surgery seems to be a useful treatment modality for HAC. This is the largest reported series of HAC treated with MMS with long-term follow-up.

    Symptomatic intracranial hemorrhage (ICH) may lead to permanent neurological disability of patients and has impeded the extensive clinical application of deep brain stimulation (DBS). The present study was conducted to discuss the incidence, prevention, and treatment of symptomatic ICH after DBS surgery. From January 2009 to December 2014, 396 patients underwent DBS with a total of 691 implanted leads. In all, 10 patients had symptomatic ICH. We analyzed these cases' clinical characteristics, including comorbid diagnoses and coagulation profile. We described the onset of ICH, imaging features, clinical manifestations, treatment, neurological impairment, and outcome of DBS. Of the 10 patients with symptomatic ICH, 2 had hypertension. Three cases of ICH occurred within 12 h of the procedure; four cases within 24 h. Five experienced grand mal seizures concurrently with hemorrhage. Unilateral frontal lobe hemorrhage occurred in all cases. In seven cases, hematomas occurred around the electrodes. Some hematomas were not well-circumscribed and had perihematomal edema. Conservative therapy was administered to 8 patients, and 2 patients underwent craniotomy and hematoma evacuation. All electrodes were successfully preserved. Neurological dysfunction in all patients gradually improved. Nine patients ultimately experienced effective symptom relief of Parkinson's disease with DBS. Symptomatic ICH should be identified as soon as possible after implantation surgery and treated effectively to limit neurological deficit and preserve DBS leads.

  9. From Diagnosis to Treatment: Clinical Applications of Nanotechnology in Thoracic Surgery (United States)

    Digesu, Christopher S.; Hofferberth, Sophie C.; Grinstaff, Mark W.; Colson, Yolonda L.


    Synopsis Nanotechnology is an emerging field of medicine with significant potential to become a powerful adjunct to cancer therapy, and in particular, thoracic surgery. Using the unique properties of several different nanometer-sized platforms, therapy can be delivered to tumors in a more targeted fashion, with less of the systemic toxicity associated with traditional chemotherapeutics. In addition to the packaged delivery of chemotherapeutic drugs, nanoparticles show potential to aid in the diagnosis, pre-operative characterization, and intraoperative localization of thoracic tumors and their lymphatics. With increasing interest in their clinical application, there is a rapid expansion of in vitro and in vivo studies being conducted that provide a better understanding of potential toxicities and hopes of broader clinical translation. Focused research into nanotechnology’s ability to deliver both diagnostics and therapeutics has led to the development of a field known as nanotheranostics which promises to improve the treatment of thoracic malignancies through enhanced tumor targeting, controlled drug delivery, and therapeutic monitoring. This article reviews the various types of nanoplatforms, their unique properties, and the potential for clinical application in thoracic surgery. PMID:27112260

    Full Text Available Abstract Background Several guidelines on adeno-tonsillar disease have been proposed in recent years and some discrepancies in relation both to clinical manifestations and indications for surgical treatment have emerged. The aim of the study was to verify what influence (adeno-tonsillectomy guidelines have had on the clinical behaviour of ENT specialists in Italy. Our study is a retrospective and multi-centre case series with chart review. Methods The survey involved 14,770 children, aged between the ages of 2 and 11, who had undergone adeno-tonsillar surgery between 2002 and 2008 in fourteen Italian tertiary and secondary referral centres. Anova test was used for the statistical analysis, assuming p Results The frequency of adeno-tonsillar surgeries did not change significantly (p>0.05 during the study period and following the Italian policy document publication. Overall, adeno-tonsillectomy was the most frequent intervention (64.1%, followed by adenoidectomy (31.1% and tonsillectomy (4.8%. The indications for surgery did not change significantly for each of the operations (p>0.05, with the exception of adeno-tonsillectomy in case of feverish episodes due to acute recurrent tonsillitis ≥ 5 without nasal obstruction (decreased p= 0.010 , even when the feverish episodes due to acute recurrent tonsillitis were Conclusions The recommendations first developed in Italy in a 2003 policy document and then resumed in guidelines in 2008, were not implemented by ENT units involved in the survey. The study highlights the fact that the indications for adeno-tonsillar operations are based on the overall clinical presentation (comorbidity rather than on a single symptom. Guidelines are necessary to give coherent recommendations based on both the findings obtained through randomized controlled trials and the data collected from observational studies.

  13. Oral magnesium supplementation reduces the incidence of gastrointestinal complications following cardiac surgery: a randomized clinical trial. (United States)

    Moradian, Seyed Tayeb; Ghiasi, Mohammad Saeid; Mohamadpour, Alireza; Siavash, Yadollah


    Gastrointestinal complications are common after coronary artery bypass graft surgery. These complications are ranged from nausea and vomiting to mesenteric ischemia and liver failure. It seems that nausea, vomiting, and constipation are related to magnesium deficiency. This study was designed to examine the effect of oral magnesium supplementation on the incidence of gastrointestinal complications in patients undergoing cardiac surgery. In a single blinded randomized clinical trial, 102 patients who were undergoing coronary artery bypass graft surgery were randomly allocated into two groups, 52 patients in the intervention and 50 patients in control group. Patients in the experimental group received 800 milligram magnesium oxide (2 tablets each of them containing 240 mg elemental magnesium) daily from the admission to discharge from hospital. The incidence of post-operative nausea and vomiting, constipation, and atrial fibrillation was compared between the groups. Our results showed that postoperative hypomagnesemia is present in 41.20 and 70.80 percent of the patients in the intervention and control group patients, respectively. The overall incidence of constipation was 62%. Patients who received magnesium supplementation experienced less atrial fibrillation, nausea, vomiting, and constipation. Our data showed that oral magnesium supplementation could reduce the postoperative complications. Despite the better status in the intervention group, the hypomagnesemia was present in many of intervention group patients. It seems that supplementation with higher doses is needed.

    Gosling, D B; Chan, T K J


    PurposeTo report the clinical experience of using the Tecnis PCB00 (Abbott Medical Optics, Santa Ana, CA, USA) preloaded one-piece intraocular lens (IOL) in the setting of a tertiary referral centre for paediatric cataract.MethodsA retrospective case note review of all paediatric cataract surgeries using the Tecnis PCB00 IOL, at a single UK paediatric ophthalmology department.ResultsNine eyes in seven patients received the IOL between December 2014 and January 2016. All patients underwent lens aspiration and insertion of the IOL 'in the bag.' The indications for surgery included developmental cataract (8/9) and traumatic cataract (1/9). Mean age at the time of surgery was 7 years (range 2-14). The median improvement in logMAR best-corrected visual acuity was 0.475 (range 0.250-1.500). The mean follow-up duration was 5 months (range 1-13). No operative or post-operative complications occurred as a result of using the device.ConclusionThe Tecnis PCB00 preloaded IOL appears to be a safe and effective device in treating paediatric cataract.

  16. Comparison of the clinical and quality-of-life outcomes after the inside-out TVT-O procedure with or without concomitant transvaginal gynaecological surgery. (United States)

    Cho, M K; Kim, C H; Kang, W D; Kim, J W; Kim, S M; Kim, Y H


    The study was undertaken to compare the clinical and quality-of-life (QoL) outcomes of the inside-out transobturator vaginal tape (TVT-O)-only procedures and TVT-O procedures with concomitant transvaginal gynaecological surgery for the treatment of stress urinary incontinence (SUI). A review of charts from January 2006 to March 2010 identified 305 patients with urodynamic stress incontinence for whom we performed the TVT-O. Of the initial 305 patients, 272 (89.2%) were re-examined for complications 1 month, 4 months, 1 year and 2-4 years postoperatively (122 TVT-O only; 150 TVT-O + other transvaginal gynaecological surgery). They were also evaluated with the Urogenital Distress Inventory Questionnaire (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) 1-4 years after the procedure. The median follow-up was 37.3 months. The success rate was 89.3% in the TVT-O-only group vs 93.3% in the TVT-O with concomitant gynaecological surgery group (p =0.729). The QoL score was quite good for 91.8% of the TVT-O-only patients and for 96.7% of the TVT-O with concomitant gynaecologic surgery patients (p =0.405). In conclusion, gynaecological operations performed concomitantly with the TVT-O procedure do not affect the clinical and QoL outcomes of the TVT-O procedure.

    Czarnetzki, Christoph; Elia, Nadia; Frossard, Jean-Louis; Giostra, Emiliano; Spahr, Laurent; Waeber, Jean-Luc; Pavlovic, Gordana; Lysakowski, Christopher; Tramèr, Martin R


    Patients undergoing emergency procedures under general anesthesia have impaired gastric emptying and are at high risk for aspiration of gastric contents. Erythromycin has strong gastric prokinetic properties. To evaluate the efficacy of erythromycin lactobionate in gastric emptying in patients undergoing emergency surgery. The Erythro-Emerge trial was a single-center, randomized, double-blinded, placebo-controlled clinical trial in patients undergoing emergency surgery under general anesthesia at Geneva University Hospitals. We included 132 patients from March 25, 2009, through April 10, 2013, and all patients completed the study. Randomization was stratified for trauma and nontrauma procedures. The randomization code was opened on April 23, 2013, and analyses were performed through July 26, 2013. We performed an intention-to-treat analysis. Patients were randomized to intravenous erythromycin lactobionate, 3 mg/kg, or placebo 15 minutes before tracheal intubation. Patients were followed up for 24 hours. The primary outcome was a clear stomach, defined as less than 40 mL of liquids and no solids and identified through endoscopy immediately after intubation. The secondary outcome was the pH level of residual gastric content. A clear stomach was diagnosed in 42 of 66 patients (64%) receiving placebo compared with 53 of 66 patients (80%) receiving erythromycin (risk ratio, 1.26 [95% CI, 1.01-1.57]). In the population undergoing surgery for nontrauma, the association between receipt of erythromycin and having a clear stomach (adjusted odds ratio [95% CI]) was statistically significant (13.4 [1.49-120]; P = .02); in the population undergoing surgery for trauma, it was not (1.81 [0.64-5.16]; P = .26). Median (interquartile range) pH of the residual gastric liquid was 2 (1-4) in 36 patients receiving placebo and 6 (3-7) in 16 receiving erythromycin (P = .002). Patients receiving erythromycin had nausea (20 [30%] vs 4 [6%]) and stomach cramps (15 [23%] vs 2 [3

  18. Clinical Predictors of Diabetes Insipidus After Transcranial Surgery for Pituitary Adenoma. (United States)

    Wang, Songquan; Li, Deling; Ni, Ming; Jia, Wang; Zhang, Qing; He, Jue; Jia, Guijun


    Diabetes insipidus (DI) is a well-known complication of transsphenoidal pituitary adenoma surgery. However, the risk factors for DI after transcranial surgery have not been clarified. In this study, the clinical parameters for predicting DI after transcranial surgery were investigated. The perioperative records of 90 patients who underwent transcranial (TC) surgery at the authors' institution between November 2011 and March 2013 were chosen from 1657 patients with pituitary adenoma and retrospectively analyzed. The degree of deformation of the third ventricle and hypothalamus were assessed by preoperative magnetic resonance imaging. Immediate postoperative DI was found in 30 patients (33.3%). Persistent DI was noted in 11 patients (12.6%). Compared with patients in the nonpostoperative DI group, those with postoperative DI had a higher degree of deformation of the third ventricle and hypothalamus (P < 0.001). In a binary logistic regression analysis, the degree of deformation of the third ventricle and hypothalamus (odds ratio [OR], 3.079; 95% confidence interval [CI], 1.600-5.925; P = 0.001) had a significant positive correlation with immediate postoperative DI, as well as postoperative hemorrhage (OR, 6.235, 95% CI, 1.457-26.689; P = 0.014). Postoperative hemorrhage (OR, 4.363; 95% CI, 1.021-18.647; P = 0.047) showed a positive correlation with permanent DI, as well as the degree of deformation of the third ventricle and hypothalamus (OR, 2.336; 95% CI, 1.005-5.427; P = 0.049). The degree of deformation of the third ventricle and hypothalamus assessed by preoperative magnetic resonance imaging may help to predict postoperative DI. Postoperative hemorrhage might increase the incidence of postoperative DI, whether it is immediate postoperative DI or permanent DI. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Purpose. To evaluate the clinical outcomes after uncomplicated cataract surgery with implantation of an aspheric toric intraocular lens (IOL during a 6-month follow-up. Methods. Prospective study including 27 consecutive eyes of 18 patients (mean age: 66.1±11.4 years with a visually significant cataract and corneal astigmatism ≥ 0.75 D and undergoing uncomplicated cataract surgery with implantation of the Tecnis ZCT toric IOL (Abbott Medical Optics. Visual, refractive, and keratometric outcomes as well as IOL rotation were evaluated during a 6-month follow-up. At the end of the follow-up, patient satisfaction and perception of optical/visual disturbances were also evaluated using a subjective questionnaire. Results. At 6 months after surgery, mean LogMAR uncorrected (UDVA and corrected distance visual acuity (CDVA were 0.19±0.12 and 0.14±0.10, respectively. Postoperative UDVA of 20/40 or better was achieved in 92.6% of eyes. Mean refractive cylinder decreased significantly from −3.73±1.96 to −1.42±0.88 D (p<0.001, while keratometric cylinder did not change significantly (p=0.44. Mean absolute IOL rotation was 1.1±2.4°, with values of more than 5° in only 2 eyes (6.9%. Mean patient satisfaction score was 9.70±0.46, using a scale from 0 (not at all satisfied to 10 (very satisfied. No postoperative optical/visual disturbances were reported. Conclusion. Cataract surgery with implantation of the Tecnis toric IOL is an effective method of refractive correction in eyes with corneal astigmatism due to the good IOL positional stability, providing high levels of patient’s satisfaction.

  20. [Spinal cord stimulation and failed back surgery syndrome. Clinical results with laminectomy electrodes]. (United States)

    García March, Guillermo; Bordes, Vicente; Roldán, Pedro; Real, Luis; González Darder, José Manuel


    Spinal cord stimulation is a widely-accepted technique in the treatment of back pain resulting from failed back surgery. Classically, stimulation has been carried out with percutaneous electrodes implanted under local anaesthesia and sedation. However, the ease of migration and the difficulty of reproducing electrical paresthesias in large areas with such electrodes has led to increasing use of surgical plate leads, which have the disadvantage of the need for general anaesthesia and a laminectomy for implantation. Our objective was to report the clinical results, technical details, advantages and benefits of laminectomy lead placement under epidural anaesthesia in failed back surgery syndrome cases. Spinal cord stimulation was performed in a total of 119 patients (52 men and 67 women), aged between 31 and 73 years (average, 47.3). Epidural anaesthesia was induced with ropivacaine. In all cases we inserted the octapolar or 16-polar lead in the epidural space through a small laminectomy. The final position of the leads was the vertebral level that provided coverage of the patient's pain. The electrodes were connected at dual-channel or rechargeable pulse generators. After a mean follow-up of 4.7 years, the results in terms of improvement of the previous painful situation was satisfactory, with an analgesia level of 58% of axial pain and 60% of radicular pain in more than 70% of cases. None of the patients said that the surgery stage was painful or unpleasant. No serious complications were included in the group, but in 6 cases the system had to be explanted because of ineffectiveness or intolerance of long-term neurostimulation. This study, with a significant number of patients, used epidural anaesthesia for spinal cord stimulation of lead implants by laminectomy in failed back surgery syndromes. The technique seems to be safe and effective. Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España. All rights reserved.

  1. Mandibular third molar surgery in 396 patients at a Norwegian university clinic: Morbidity recorded after 1 week utilizing an e-infrastructure for clinical research. (United States)

    Øyri, Hauk; Bjørnland, Tore; Barkvoll, Pål; Jensen, Janicke Liaaen


    To evaluate morbidity 1 week after mandibular third molar (3M) surgery in the authors' department. A prospective 1-year clinical study of patients followed up for 1 week after 3M surgery was performed. Consecutive patients of 18 years or older having 3M surgery under local anaesthesia were included. Patients not able to attend a follow-up appointment after 1 week were excluded. Demographic data, indication for surgery and clinical findings were recorded. Outcome variables were days requiring analgesic, days absent from work/school and complications. All data recording was performed utilizing an e-infrastructure for clinical research (InReach, University Health Network, Three hundred and ninety-six patients were examined 1 week after surgery. Mean number of days requiring analgesics was 3.8 and mean number of days absent from work/school after surgery was 0.6. Minor complications were reported by 7% of patients. Female patients reported more days requiring analgesics compared to male patients. Smokers had a higher odds ratio for being absent ≥ 3 days. Prophylactic removal of 3Ms was associated with fewer days requiring analgesics and days absent from work/school as compared to teeth with local disease. Overall morbidity after 3M surgery was low. Compared to patients subjected to therapeutic removal of 3Ms, patients undergoing prophylactic removal seem to have less pain and a faster return to normal activities.

    Limited data have been reported on bariatric surgery within a large, high-volume regional multicenter integrated healthcare delivery system. Review clinical characteristics and short- and intermediate-term outcomes and adverse events from a bariatric surgery program within an integrated healthcare delivery system. Single high-volume, multicenter regional integrated healthcare delivery system. Adult patients who underwent primary bariatric surgery during 2010-2011 were reviewed. Clinical characteristics, outcomes, and weight loss results were extracted from the electronic medical record. A total of 2399 patients were identified within the study period. The 30-day rates of clinical outcomes for Roux-en-Y gastric bypass (RYGB; n = 1313) and sleeve gastrectomy (SG; n = 1018) were 2.9% for readmission, 3.0% for major complications, .8% for reoperation, and 0% for mortality. One-year and 2-year weight loss results were as follows: percent weight loss (%WL) was 31.4 (±SD 8.5) and 34.2±12.0% for SG and 34.1±9.3 and 39.1±11.9 for RYGB; percent excess weight loss (%EBWL) was 64.2±18.0 and 69.8±23.7 for SG and 68.0±19.3 and 77.8±23.7 for RYGB; percent excess body mass index loss (%EBMIL) was 72.9±21.0 and 77.7±22.4 for SG and 76.6±22.1% and 85.6±21.6 for RYGB. Follow-up for each procedure at 1 year was 76% for SG (n = 778) and 80% for RYGB (n = 1052) and at 2 years was 65% for SG (n = 659) and 67% for RYGB (n = 875). A large regional high-volume multicenter bariatric program within an integrated healthcare delivery system can produce excellent short-term results with low rates of short- and intermediate-term adverse outcomes.

  3. Randomized clinical trial of surgery versus conservative therapy for carpal tunnel syndrome [ISRCTN84286481

    Directory of Open Access Journals (Sweden)

    Turner Judith A


    Full Text Available Abstract Background Conservative treatment remains the standard of care for treating mild to moderate carpal tunnel syndrome despite a small number of well-controlled studies and limited objective evidence to support current treatment options. There is an increasing interest in the usefulness of wrist magnetic resonance imaging could play in predicting who will benefit for various treatments. Method and design Two hundred patients with mild to moderate symptoms will be recruited over 3 1/2 years from neurological surgery, primary care, electrodiagnostic clinics. We will exclude patients with clinical or electrodiagnostic evidence of denervation or thenar muscle atrophy. We will randomly assign patients to either a well-defined conservative care protocol or surgery. The conservative care treatment will include visits with a hand therapist, exercises, a self-care booklet, work modification/ activity restriction, B6 therapy, ultrasound and possible steroid injections. The surgical care would be left up to the surgeon (endoscopic vs. open with usual and customary follow-up. All patients will receive a wrist MRI at baseline. Patients will be contacted at 3, 6, 9 and 12 months after randomization to complete the Carpal Tunnel Syndrome Assessment Questionnaire (CTSAQ. In addition, we will compare disability (activity and work days lost and general well being as measured by the SF-36 version II. We will control for demographics and use psychological measures (SCL-90 somatization and depression scales as well as EDS and MRI predictors of outcomes. Discussion We have designed a randomized controlled trial which will assess the effectiveness of surgery for patients with mild to moderate carpal tunnel syndrome. An important secondary goal is to study the ability of MRI to predict patient outcomes.

  4. Robotic versus laparoscopic surgery for rectal cancer: a comparative study of clinical outcomes and costs. (United States)

    Ielpo, Benedetto; Duran, H; Diaz, E; Fabra, I; Caruso, R; Malavé, L; Ferri, V; Nuñez, J; Ruiz-Ocaña, A; Jorge, E; Lazzaro, S; Kalivaci, D; Quijano, Y; Vicente, E


    The costs involved in performing robotic surgery present a critical issue which has not been well addressed yet. The aims of this study are to compare the clinical outcomes and cost differences of robotic versus laparoscopic surgery in the treatment of rectal cancer and to conduct a literature review of the cost analysis. This is an observational, comparative study whereby data were abstracted from a retrospective database of patients who underwent laparoscopic and robotic rectal resection from October 2010 to March 2017, at Sanchinarro University Hospital, Madrid. An independent company performed the financial analysis, and fixed costs were excluded. A total of 86 robotic and 112 laparoscopic rectal resections were included. The mean operative time was significantly lower in the laparoscopic approach (336 versus 283 min; p = 0.001). The main pre-operative data, overall morbidity, hospital stay and oncological outcomes were similar in both groups, except for the readmission rate (robotic: 5.8%, laparoscopic: 11.6%; p = 0.001). The mean operative costs were higher for robotic surgery (4285.16 versus 3506.11€; p = 0.04); however, the mean overall costs were similar (7279.31€ for robotic and 6879.8€ for the laparoscopic approach; p = 0.44). We found four studies reporting costs, three comparing robotic versus laparoscopy costs, with all of them reporting a higher overall cost for the robotic rectal resection. Robotic rectal resection has similar clinical outcomes to that of the conventional laparoscopic approach. Despite the higher operative costs of robotic rectal resection, overall mean costs were similar in our series.

  5. Clinical indications and perspectives for intraoperative cone-beam computed tomography in oral and maxillofacial surgery. (United States)

    Pohlenz, Philipp; Blessmann, Marco; Blake, Felix; Heinrich, Sven; Schmelzle, Rainer; Heiland, Max


    Intraoperative cone-beam computerized tomography (CBCT) imaging has been introduced in oral and maxillofacial surgery. Using midfacial fractures as the pioneer model, this study describes the spectrum of further promising clinical indications for intraoperative CBCT and a clinical combination with intraoperative navigation. One hundred seventy-nine patients admitted for surgical treatment of the facial skeleton were included in the study. Intraoperatively, 3-dimensional images were generated with the mobile CBCT scanner Arcadis Orbic 3D, obtained from Siemens Medical Solutions, in a variety of indications. The acquisition of the data sets was uncomplicated, and image quality was sufficient to assess the postoperative result in all cases. In the example of a facial gunshot injury, a navigation system for intraoperative localization of the metal foreign bodies was used.

  6. Post-Surgical Clinical Monitoring of Soft Tissue Wound Healing in Periodontal and Implant Surgery. (United States)

    Pippi, Roberto


    Clinical features of surgical soft tissue wound healing in dentistry have been rarely discussed in the international literature. The aim of the present paper is to highlight both the main clinical findings of surgical wound healing, especially in periodontal and implant dentistry, and the wound healing monitoring procedures which should be followed. Wound inspection after careful food and plaque debridement is the essential part of wound healing monitoring. Periodontal and peri-implant probing should be performed only after tissue healing has been completed and not on a weekly basis in peri-implant tissue monitoring. Telephone follow-up and patient self-assessment scales can also be used the days following surgery to monitor the most common surgical complications such as pain, swelling, bleeding, and bruising. Wound healing monitoring is an important concern in all surgical procedures since it allows to identify signs or/and symptoms possibly related to surgical complications.

  7. Relationship between magnetic resonance imaging and clinical results of decompression surgery for cervical myelopathy

    International Nuclear Information System (INIS)

    Okumura, Hiroshi


    MR imaging was investigated before and after surgery in 60 cases of cervical myelopathy. A preoperative high-signal-intensity area in the spinal cord was thought to be an important indicator of poor prognosis, because the recovery ratio of the preoperative high-signal group was 32±24%, while that of the normal-signal group was 86±15%. But, a high-signal-intensity area had no significant correlation with the morbidity period, preoperative clinical severity and degree of cord compression. There was a significant correlation between postoperative MR imaging and the neurological prognosis. And, atrophy and high-signal-intensity area in the spinal cord were frequently seen in cases of poor neurological postoperative recovery, corresponding to the morbidity period, preoperative clinical severity and degree of cord compression. MR imaging can serve as a useful tool to assess cervical myelopathy and to forecast the postoperative prognosis. (author)

  8. Clinical significance of 201Tl reverse redistribution in patients with aorto-coronary bypass surgery

    International Nuclear Information System (INIS)

    Nishimura, Tsunehiko; Uehara, Tashiisa; Hayashida, Kohei; Kozuka, Takahira


    Detection of myocardial ischemia by the stress thallium scan has traditionally been performed using transient defect analysis on exercise, followed by redistribution studies. Worsening of the 201 Tl myocardial image from exercise to redistribution is referred to as reverse redistribution. In this study, we found reverse redistribution in 10 (21%) of 48 angina pectoris patients who had undergone aortocoronary bypass surgery. The clinical significance of this phenomenon in these patients was investigated in relation to angiographic and surgical findings. Reverse redistribution was found to occur in regions which were supplied by bypass grafts. These areas showed increased coronary blood flow and rapid thallium washout. Our results indicate that a perfusion defect in the bypass region of the redistribution image might be caused by relatively rapid washout in the bypass graft region compared to the adjacent normal myocardium. These results should be considered in the clinical interpretation of stress thallium scans. (orig.)

  9. [Quality of oral surgery and patients' satisfaction in state and municipal clinics]. (United States)

    Kayalov, R M; Abakarov, S I; Grinin, V M

    The aim of the multicenter study was to assess quality of oral surgical procedures and patients' satisfaction in state and municipal clinics in different regions of Russian Federation. A questionnaire survey was conducted in 3 regions of Russian Federation: European (Moscow, Tula, Tambov, Kaluga, Volgograd), North (Saint-Petersburg, Novgorod, Tver) and South (Armavir, Derbent, Kaspiysk, Kislovodsk, Makhachkala, Pyatigorsk, Rostov, Sochi, Stavropol). Sixty-six males and 34 females undergoing surgical dental treatment in public and municipal dental clinics (total number - 100 patients) at the age of 20 to 70 years (an average age was 36,3 and 39.5, respectively) were included in the study. Comparative analysis of patients' satisfaction rates in relation with expert evaluated quality of oral surgery is presented.

  10. Image-Guided Surgery Using Invisible Near-Infrared Light: Fundamentals of Clinical Translation

    Directory of Open Access Journals (Sweden)

    Sylvain Gioux


    Full Text Available The field of biomedical optics has matured rapidly over the last decade and is poised to make a significant impact on patient care. In particular, wide-field (typically > 5 cm, planar, near-infrared (NIR fluorescence imaging has the potential to revolutionize human surgery by providing real-time image guidance to surgeons for tissue that needs to be resected, such as tumors, and tissue that needs to be avoided, such as blood vessels and nerves. However, to become a clinical reality, optimized imaging systems and NIR fluorescent contrast agents will be needed. In this review, we introduce the principles of NIR fluorescence imaging, analyze existing NIR fluorescence imaging systems, and discuss the key parameters that guide contrast agent development. We also introduce the complexities surrounding clinical translation using our experience with the Fluorescence-Assisted Resection and Exploration (FLARE™ imaging system as an example. Finally, we introduce state-of-the-art optical imaging techniques that might someday improve image-guided surgery even further.

  11. Academic Productivity, Knowledge, and Education in Plastic Surgery: The Benefit of the Clinical Research Fellow. (United States)

    Carney, Martin J; Weissler, Jason M; Koltz, Peter F; Fischer, John P; Wu, Liza C; Serletti, Joseph M


    Academic research productivity is limited by strenuous resident and faculty schedules but nevertheless is imperative to the growth and success of our discipline. The authors report institutional experience with their clinical research fellowship model, providing two positions per year. A critical analysis of research productivity was performed for all trainees, faculty, and research fellows from 2000 to 2015. Academic productivity was determined by the number of peer-reviewed publications, podium presentations, and h-index. Academic fate of previous research fellows was also noted. During the 16-year timeframe, 484 articles were published in print. Notably, 92 articles were published from 2000 to 2007 and 392 articles were published from 2008 to 2015 (p = 0.0066), demonstrating linear growth after instituting the research fellowship. In addition, 33 articles were published from 2002 to 2004 before leadership change, 47 from 2005 to 2007 after leadership change but before fellowship, and 58 from 2008 to 2010 in the first few years of the fellowship (p = 0.0204). Overall, 39.9 percent of publications appeared in Plastic and Reconstructive Surgery, with a total of 77 different peer-reviewed journal inclusions. American Association of Plastic Surgeons, American Society of Plastic Surgeons, and Northeastern Society of Plastic Surgeons podium presentations totaled 143 between 2005 and 2015. Of the eight previous fellows who applied into integrated and independent programs, 100 percent have matched. Incorporation of a formalized research fellowship into a plastic surgery program can drastically increase clinical research contribution in a reproducible fashion.

  12. Clinical and metabolic results of fasting abbreviation with carbohydrates in coronary artery bypass graft surgery. (United States)

    Feguri, Gibran Roder; Lima, Paulo Ruiz Lúcio; Lopes, Andréa Mazoni; Roledo, Andréa; Marchese, Miriam; Trevisan, Mônica; Ahmad, Haitham; Freitas, Bruno Baranhuk de; Aguilar-Nascimento, José Eduardo de


    Limited information is available about preoperative fasting abbreviation with administration of liquid enriched with carbohydrates (CHO) in cardiovascular surgeries. To evaluate clinical variables, security of the method and effects on the metabolism of patients undergoing fasting abbreviation in coronary artery bypass graft (CABG) surgery. Forty patients undergoing CABG were randomized to receive 400 ml (6 hours before) and 200 ml (2 hours before) of maltodextrin at 12.5% (Group I, n=20) or just water (Group II, n=20) before anesthetic induction. Perioperative clinical variables were evaluated. Insulin resistance (IR) was evaluated by Homa-IR index and also by the need of exogenous insulin; pancreatic beta-cell excretory function by Homa-Beta index and glycemic control by tests of capillary glucose. Deaths, bronchoaspiration, mediastinitis, stroke and acute myocardial infarction did not occur. Atrial fibrillation occurred in two patients of each group and infectious complications did not differ among groups (P=0.611). Patients of Group I presented two days less of hospital stay (P=0.025) and one day less in the ICU (P0.05). A decline in the endogenous production of insulin was observed in both groups (P<0.001). Preoperative fasting abbreviation with the administration of CHO in the CABG was safe. The glycemic control improved in the ICU; there was less time in the use of dobutamine and length of hospital and ICU stay was reduced. However, neither IR nor morbimortality during hospital phase were influenced.

  15. Clinical significance of surgery for gastric submucosal tumours with size enlargement during watchful waiting period. (United States)

    Miyazaki, Yasuhiro; Nakajima, Kiyokazu; Kurokawa, Yukinori; Takahashi, Tsuyoshi; Takiguchi, Shuji; Miyata, Hiroshi; Yamasaki, Makoto; Hirota, Seiichi; Nishida, Toshirou; Mori, Masaki; Doki, Yuichiro


    The true impact of surgery for small, asymptomatic and biopsy-negative gastric submucosal tumours (SMTs) with size enlargement during 'watchful waiting' period has not been fully understood. From 2005 to 2012, 100 patients with gastric SMTs underwent surgery. Twenty-three of them with size enlargement during observation period were enrolled in the retrospective analysis. Data included clinicopathologic findings, genetic findings, operative outcomes and prognoses. All patients (13 males, 10 females), with median age of 54 (41-71), had their lesions detected by routine health check-up (n=21) or incidentally (2). The tumours were 1.8 (0.5-4.0)cm in size at their initial detection, and enlarged up to 3.2 (2.0-7.0)cm at the operation during 63.0 (14.6-233.7) months. As surgical procedure, laparoscopic partial gastrectomy accounted for the majority (78.3%). Histologic examination revealed gastrointestinal stromal tumour (GIST) (21) and schwannoma (2). Although 16 out of 21 GISTs were categorised into 'Very low' (1), and 'Low' (13) risk according to Fletcher's classification, 'Intermediate' (5) and 'High' (2) risk were identified in the series. No recurrences/metastases were noted in 23.2 (0.9-87) months of postoperative follow-up. Our study revealed the existence of high mitotic GISTs in asymptomatic, small gastric SMTs with size enlargement, and laparoscopic surgery was safely applied to majority of those cases. Prompt surgical intervention should therefore be considered for those lesions. Copyright © 2013 Elsevier Ltd. All rights reserved.

  16. A Prospective Assessment of Clinical and Patient-Reported Outcomes of Initial Non-Operative Management of Ventral Hernias. (United States)

    Holihan, Julie L; Flores-Gonzalez, Juan R; Mo, Jiandi; Ko, Tien C; Kao, Lillian S; Liang, Mike K


    Little is known about the clinical or patient-reported outcomes with non-operative management of ventral hernias. The aim of this prospective study is to determine the clinical and patient-reported outcomes of patients undergoing initial non-operative treatment of their ventral hernia. This was a prospective observational study of patients undergoing non-operative management of ventral hernias. Primary outcome was rate of surgical repair of the ventral hernias. Secondary outcomes included rate of emergency repair, elective repair, and emergency room visits. In addition, validated measurement tools for patient satisfaction and cosmetic satisfaction with their abdomen, abdominal pain, and patient function (modified Activities Assessment Scale, AAS) were utilized. Of 128 patients who underwent non-operative management of a ventral hernia, 99(77.3%) patients were followed for a median (interquartile range) of 12.2(10.4-13.5) months. Twenty (20.2%) patients had at least 1 emergency room visit associated with their hernia. One-quarter (n = 2323.2%) underwent ventral hernia repair following enrollment. Twenty (20.2%) underwent elective repair, and 3 (3.0%) underwent emergent repair. Based on the modified AAS survey, patients who were managed non-operatively experienced no change in patient centered outcomes, while patients converted to operative management had improved scores. While the short-term risk of emergency surgery with non-operative management of ventral hernias is moderate, the chance of an emergency room visit and surgery is high. Patients who undergo non-operative management of their ventral hernias have no change in patient-reported outcomes at one year, while those converted to operative management experience improvement.

  18. The Effectiveness of Nurse-Led Preoperative Assessment Clinics for Patients Receiving Elective Orthopaedic Surgery: A Systematic Review. (United States)

    Sau-Man Conny, Chan; Wan-Yim, Ip


    Nurse-led preoperative assessment clinics (POAC) have been introduced in different specialty areas to assess and prepare patients preoperatively in order to avoid last-minute surgery cancellations. Not all patients are referred to POACs before surgery, and the benefits of nurse-led POACs are not well documented in Hong Kong. The purpose of this systemic review was to identify the best available research evidence to inform current clinical practice, guide health care decision making and promote better care. The Joanna Briggs Institute (JBI) approach for conducting systematic review of quantitative research was used. Data bases searched included all published and unpublished studies in Chinese and English. All studies with adult patients who required elective orthopaedic surgery e.g. total knee replacement, total hip replacement, reduction of fracture or reconstruction surgery etc. in a hospital or day surgery center and attended a nurse-led POAC before surgery were included. Ten studies were critically appraised. Results showed that nurse-led POACs can reduce surgery cancellation rates. These studies suggested a reduction in the rate of postoperative mortality and length of hospital stay. In addition, the level of satisfaction towards services provided was significantly high. Although POACs are being increasingly implemented worldwide, the development of clinical guidelines, pathways and protocols was advocated. The best available evidence asserted that nurses in the POAC could serve as effective coordinators, assessors and educators. The nurse-led practice optimized patients' condition before surgery and hence minimized elective surgery cancellations. Copyright © 2016 American Society of PeriAnesthesia Nurses.

    Vujovic, Olga; Yu, Edward; Cherian, Anil; Perera, Francisco; Dar, A. Rashid; Stitt, Larry; Hammond, A.


    Purpose: To examine the effect of clinical presentation and interval to breast surgery on local recurrence and survival in early-stage breast cancer. Methods and Materials: The data from 397 patients with Stage T1-T2N0 breast carcinoma treated with conservative surgery and breast radiotherapy between 1985 and 1992 were reviewed at the London Regional Cancer Program. The clinical presentation consisted of a mammogram finding or a palpable lump. The intervals from clinical presentation to definitive breast surgery used for analysis were 0-4, >4-12, and >12 weeks. The Kaplan-Meier estimates of the time to local recurrence, disease-free survival, and cause-specific survival were determined for the three groups. Cox regression analysis was used to evaluate the effect of clinical presentation and interval to definitive surgery on survival. Results: The median follow-up was 11.2 years. No statistically significant difference was found in local recurrence as a function of the interval to definitive surgery (p = .424). A significant difference was noted in disease-free survival (p = .040) and cause-specific survival (p = .006) with an interval of >12 weeks to definitive breast surgery. However, the interval to definitive surgery was dependent on the presentation for cause-specific survival, with a substantial effect for patients with a mammographic presentation and a negligible effect for patients with a lump presentation (interaction p = .041). Conclusion: The results of this study suggest that an interval of >12 weeks to breast surgery might be associated with decreased survival for patients with a mammographic presentation, but it appeared to have no effect on survival for patients presenting with a palpable breast lump.

    Holub, Z.; Kliment, L.; Jabor, A.; Sprongl, L.


    Objective was to determine the differences in inflammatory response and clinical outcome of current clinical practice in women undergoing laparoscopic myomectomy (LM) and abdominal myomectomy (AM) for symptomatic fibroid. A total of 36 women entered the study between October 2004 to June 2005 at the Department of Gynecology and Obstetrics and the Endosopy Training Center at the Baby Friendly Hospital in Klando, Czech Republic, based upon an ultrasonographic assessment size of dominant fibroid (DM) before surgery. All women were allocated to one of 2 groups: group 1 (n=17), DM -6cm, treated with open myomectomy. Surgical characteristics, hospital stay and complications were analyzed. Blood samples for assay of the acute phase reactants and markers of tissue trauma [C-reactive protein (CRP), interleukin-6 (IL-6), serum amyloid kinase (CK)] were taken preoperatively and on the first and third postoperative day. The difference between the groups in mean size of DM was statistically significant (4.8 cm in group 1 versus 6.9 cm in group 2, p<0.05). Statistically, significant differences were found between the compared groups in intra-operative blood loss (p<0.05) and length of hospital stay (p<0.001). No complication was reported after LM. There were significantly higher levels of CRP, IL-6, SAA, WBC and CK in both groups after surgery. Increased levels of IL-6, WBC and CK were greatest on the first postoperative day in the open group. The serum CRP, IL-6, SAA, WBC, CK and the fall in the hemoglobin were statistically different between the 2 groups. Compared with open myomectomy, LM was associated with a less intensive inflammatory response and a more favorable clinical outcome. (author)

  1. Pricing strategy for aesthetic surgery: economic analysis of a resident clinic's change in fees. (United States)

    Krieger, L M; Shaw, W W


    The laws of microeconomics explain how prices affect consumer purchasing decisions and thus overall revenues and profits. These principles can easily be applied to the behavior aesthetic plastic surgery patients. The UCLA Division of Plastic Surgery resident aesthetics clinic recently offered a radical price change for its services. The effects of this change on demand for services and revenue were tracked. Economic analysis was applied to see if this price change resulted in the maximization of total revenues, or if additional price changes could further optimize them. Economic analysis of pricing involves several steps. The first step is to assess demand. The number of procedures performed by a given practice at different price levels can be plotted to create a demand curve. From this curve, price sensitivities of consumers can be calculated (price elasticity of demand). This information can then be used to determine the pricing level that creates demand for the exact number of procedures that yield optimal revenues. In economic parlance, revenues are maximized by pricing services such that elasticity is equal to 1 (the point of unit elasticity). At the UCLA resident clinic, average total fees per procedure were reduced by 40 percent. This resulted in a 250-percent increase in procedures performed for representative 4-month periods before and after the price change. Net revenues increased by 52 percent. Economic analysis showed that the price elasticity of demand before the price change was 6.2. After the price change it was 1. We conclude that the magnitude of the price change resulted in a fee schedule that yielded the highest possible revenues from the resident clinic. These results show that changes in price do affect total revenue and that the nature of these effects can be understood, predicted, and maximized using the tools of microeconomics.

    Therattil, Paul J; Yueh, Janet H; Kordahi, Anthony M; Cherla, Deepa V; Lee, Edward S; Granick, Mark S


    Outpatient wound care plays an integral part in any plastic surgery practice. However, compliance with hand hygiene measures has shown to be low, due to skin irritation and lack of time. The objective of this trial was to determine whether single-use, long-acting antiseptics can be as effective as standard multiple-use hand hygiene methods in an outpatient surgical setting. A prospective, randomized controlled trial was performed in the authors' outpatient plastic surgery clinic at Rutgers New Jersey Medical School, Newark, NJ to compare the efficacy of an ethyl alcohol-based sanitizer (Avagard D Instant Hand Aniseptic, 3M Health Care, St. Paul, MN), a benzalkonium chloride-based sanitizer (Soft & Shield, Bioderm Technologies, Inc, Trenton, NJ, distributed by NAPP Technologies, Hackensack, NJ ), and soap and- water handwashing. Subjects included clinic personnel, who were followed throughout the course of a 3-hour clinic session with hourly hand bacterial counts taken. During the course of the trial, 95 subjects completed the clinic session utilizing 1 of the hand hygiene methods (36 ethyl alcohol-based sanitizer, 38 benzalkonium chloride-based sanitizer, and 21 soap-and-water handwashing). There was no difference between hand bacterial counts using the different methods at 4 hourly time points (P greater than 0.05). Hand bacterial counts increased significantly over the 3-hour clinic session with the ethyl alcohol-based sanitizer (9.24 to 21.90 CFU, P less than 0.05), benzalkonium chloride-based sanitizer (6.69 to 21.59 CFU, P less than 0.05), and soap-and-water handwashing (8.43 to 22.75 CFU, P less than 0.05). There does not appear to be any difference in efficacy between single-use, long-acting sanitizer, and standard multiple-use hand hygiene methods. Hand bacterial counts increased significantly over the course of the 3-hour clinic session regardless of the hand hygiene measure used. Hand condition of subjects was improved with the ethyl alcohol

  3. Higher clinical performance during a surgical clerkship is independently associated with matriculation of medical students into general surgery. (United States)

    Daly, Shaun C; Deal, Rebecca A; Rinewalt, Daniel E; Francescatti, Amanda B; Luu, Minh B; Millikan, Keith W; Anderson, Mary C; Myers, Jonathan A


    The purpose of our study was to determine the predictive impact of individual academic measures for the matriculation of senior medical students into a general surgery residency. Academic records were evaluated for third-year medical students (n = 781) at a single institution between 2004 and 2011. Cohorts were defined by student matriculation into either a general surgery residency program (n = 58) or a non-general surgery residency program (n = 723). Multivariate logistic regression was performed to evaluate independently significant academic measures. Clinical evaluation raw scores were predictive of general surgery matriculation (P = .014). In addition, multivariate modeling showed lower United States Medical Licensing Examination Step 1 scores to be independently associated with matriculation into general surgery (P = .007). Superior clinical aptitude is independently associated with general surgical matriculation. This is in contrast to the negative correlation United States Medical Licensing Examination Step 1 scores have on general surgery matriculation. Recognizing this, surgical clerkship directors can offer opportunities for continued surgical education to students showing high clinical aptitude, increasing their likelihood of surgical matriculation.

  4. The effect of music intervention in stress response to cardiac surgery in a randomized clinical trial. (United States)

    Nilsson, Ulrica


    To evaluate the effect of bed rest with music on the first postoperative day to decrease stress for patients who have undergone heart surgery. A repeated-measures randomized controlled trial was used. The study took place in a cardiothoracic intermediary unit of a university hospital in Sweden. Fifty-eight patients who had undergone open coronary artery bypass grafting or aortic valve replacement surgery were included. Stress response was assessed by determining the serum cortisol, heart rate, respiratory rate, mean arterial pressure, arterial oxygen tension, arterial oxygen saturation, and subjective pain and anxiety levels. At 12:00 noon on postoperative day 1, patients were allocated to receive 30 minutes of uninterrupted bed rest with music and then 30 minutes of bed rest or alternatively 60 minutes of uninterrupted bed rest. The music was soft and relaxing, included different melodies in new-age style, played with a volume at 50 to 60 dB, and distributed through a music pillow connected to an MP3 player. After 30 minutes of bed rest, there was a significant difference in s-cortisol levels between the groups; 484. 4 mmol/L in the music group versus 618.8 mmol/L in the control group (P < .02). However, this difference in s-cortisol levels was not found 30 minutes later (ie, after a total of 60 minutes). There was no difference in heart rate, respiratory rate, mean arterial pressure, arterial oxygen tension, arterial oxygen saturation, and subjective pain and anxiety levels between the groups. There is sufficient practical evidence of stress reduction to suggest that a proposed regimen of listening to music while resting in bed after open heart surgery be put into clinical use.

    Falter, Florian; Razzaq, Nabeel; John, Martin; Fassl, Jens; Maurer, Markus; Ewing, Sean; Hofmeyr, Ross


    Unfractionated heparin is the mainstay of anticoagulation during cardiac surgery on cardiopulmonary bypass (CPB) due to its low cost, quick onset, and ease of reversal. Since over 30 years, the activated clotting time (ACT) has been used to assess the level of heparin activity both before and after CPB. We compared two different methods of measuring the ACT: i-STAT, which uses amperometric detection of thrombin cleavage, and Hemochron Jr, which is based on detecting viscoelastic changes in blood. We included 402 patients from three institutions (Papworth Hospital, Cambridge, UK; Groote Schuur, Cape Town, South Africa; University Hospital Basel, Basel, Switzerland) undergoing elective cardiac surgery on CPB in our study. We analyzed duplicate samples on both devices at all standard measuring points during the procedure. The correlation coefficient between two Hemochron and two i-STAT devices was .9165 and .9857, respectively. The within-subject coefficient of variation (WSCV) ranged from 8.2 to 13.6% for the Hemochron and from 4.1 to 9.1% for the i-STAT. We found that the number of occasions where one of the duplicate readings was >1,000 seconds while the other was below or close to the clinically significant threshold of 400 seconds were higher for the Hemochron. We found the i-STAT to systematically return higher measurements. We conclude that the i-STAT provides a more reliable test for heparin activity and assesses safe anticoagulation during cardiac surgery on pump. The fact the that the i-STAT reads higher than the Hemochron leads to the recommendation to validate the methods against each other before changing devices.

    The purpose of this study was to analyze clinical outcomes from cervical cancer and stratify patients into risk groups for prognostic factors for early-stage disease. We retrospectively reviewed patients with stage IB or IIA cervical cancer treated with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) following primary surgery at Samsung Medical Center from 2001 to 2011. Adjuvant RT was added for patients with intermediate-risk factors, and adjuvant CCRT was performed on high-risk patients after surgery. We reviewed 247 patients—149 in the high-risk group and 98 in intermediate-risk group. The median follow-up was 62 months. Loco-regional failure (LRF) alone occurred in 7 patients (2.8%), distant metastasis alone in 37 patients (15.0%) and LRF with DM in 4 patients (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates for both groups were 79.7% and 87.6%, respectively. In the high-risk group, the 5-year DFS and OS probabilities were 72.5% and 81.9%, respectively. Histologic type, pathologic tumor size, and the number of pelvic lymph node (PLN) metastasis were significant prognostic factors for DFS and OS. We suggest a scoring system (0–3) using these prognostic factors to predict poor prognosis in high-risk patients. Using this system, patients with higher scores have higher recurrence and lower survival rates. In the high-risk cervical-cancer group who received primary surgery and adjuvant CCRT, non-squamous type, large tumor size and the number of PLN metastasis were significant prognostic factors, and the number of these factors was associated with survival rates.

    Postoperative pneumonia is sometimes a life-threatening complication of surgery for lung cancer. We retrospectively reviewed patients who developed postoperative pneumonia after surgery for lung cancer in order to assess the clinical, microbiological, and therapeutic features of this complication. Between 2001 and 2009, 836 patients underwent pulmonary resection for lung cancer in our hospital. Postoperative pneumonia developed in 23 patients (2.8%). Diagnoses of pneumonia were performed on postoperative day 6.8±3.4 (mean± standard deviation (SD)). Plain chest radiography revealed abnormal shadows on the operative side in 20 patients; 2 patients had bilateral pneumonia and 1 underwent pneumonectomy. Computed tomography was performed in 17 patients, and, among them, 13 patients (76.5%) had infiltrative shadows in the caudal or dorsal portion of the operative side of the lung. Nine patients (39.1%) were intubated in order to perform mechanical ventilation, and 4 of them died. Sputum cultures were performed in 12 patients, and pathogenic microorganisms were isolated in 4 (33.3%). The culturing of endotracheal specimens was carried out in 12 patients; among them, normal flora of the oral cavity was isolated in 4 patients (33.3%), no microorganisms were identified in 1 patient (8.3%), and pathogenic microorganisms were isolated in 7 patients (58.3%). The patients whose specimens tested positive for pathogenic microorganisms tended to develop severe pneumonia. We conclude that the insufficient drainage of respiratory tract secretions and silent aspiration after lung surgery are associated with the development of postoperative pneumonia. Further, obtaining and analyzing lower respiratory tract secretions is an important step in the management of postoperative pneumonia. (author)

  8. Skin closure methods after single port laparoscopic surgery: a randomized clinical trial. (United States)

    Park, Sue Yeon; Kim, Kye Hyun; Yuk, Jin-Sung; Ji, Hyun Young; Lee, Jung Hun


    To compare postoperative cosmetic outcomes according to different umbilical closure methods after single port laparoscopic surgery (SP-LS). A total of 138 women who were scheduled to receive elective SP-LS were randomized to undergo closure of the umbilical incision with either a subcutaneous suture only without subcuticular skin suture (case group, n=68) or both a subcutaneous suture and subcuticular skin suture (control group, n=70) after fascial closure. At postoperative months 1 and 3, the umbilical scar was evaluated using the Vancouver scar scale (VSS), the patient and observer scar assessment scale, and a visual analog scale (VAS). Overall satisfaction with scar cosmesis and surgery was assessed with the VAS. There was no significant difference in the clinical characteristics and operative data between the groups. The objective and subjective scar assessments and the overall satisfaction with scar cosmesis were not different between the groups. In the control group, four (5.7%) women experienced wound discharge and were treated with conservative treatments and delayed closure. In women who completed the first and second assessments, the changes in the scar assessment and overall satisfaction with the scar according to time after surgery were not different in either group, but the patient scar assessment scale in both groups and the VSS in the case group improved. After SP-LS, the approximation of the fascia and subcutaneous layer seems to be enough for the closure of an umbilical incision. Skin closure with subcuticular sutures did not improve the postoperative cosmetic outcomes and might lead to impaired wound healing. However, large randomized trials with various closure techniques and materials are needed to confirm this finding. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available CONTEXT AND OBJECTIVE: Taking the outcome of mortality into consideration, there is controversy about the beneficial effects of neuraxial anesthesia for orthopedic surgery. The aim of this study was to compare the effectiveness and safety of neuraxial anesthesia versus general anesthesia for orthopedic surgery. DESIGN AND SETTING: Systematic review at Universidade Federal de Alagoas. METHODS: We searched the Cochrane Central Register of Controlled Trials (Issue 10, 2012, PubMed (1966 to November 2012, Lilacs (1982 to November 2012, SciELO, EMBASE (1974 to November 2012 and reference lists of the studies included. Only randomized controlled trials were included. RESULTS: Out of 5,032 titles and abstracts, 17 studies were included. There were no statistically significant differences in mortality (risk difference, RD: -0.01; 95% confidence interval, CI: -0.04 to 0.01; n = 1903, stroke (RD: 0.02; 95% CI: -0.04 to 0.08; n = 259, myocardial infarction (RD: -0.01; 95% CI: -0.04 to 0.02; n = 291, length of hospitalization (mean difference, -0.05; 95% CI: -0.69 to 0.58; n = 870, postoperative cognitive dysfunction (RD: 0.00; 95% CI: -0.04 to 0.05; n = 479 or pneumonia (odds ratio, 0.61; 95% CI: 0.25 to 1.49; n = 167. CONCLUSION: So far, the evidence available from the studies included is insufficient to prove that neuraxial anesthesia is more effective and safer than general anesthesia for orthopedic surgery. However, this systematic review does not rule out clinically important differences with regard to mortality, stroke, myocardial infarction, length of hospitalization, postoperative cognitive dysfunction or pneumonia.

    Full Text Available Abstract Background Sexual dysfunction following surgery for rectal cancer may be frequent and often severe. The aim of the present study is to evaluate the occurrence of this complication from both a clinical point of view and by means of neurophysiological tests. Methods We studied a group of 57 patients submitted to rectal resection for adenocarcinoma. All the patients underwent neurological, psychological and the following neurophysiological tests: sacral reflex (SR, pudendal somatosensory evoked potentials (PEPs, motor evoked potential (MEPs and sympathetic skin responses (SSRs. The results were compared with a control group of 67 rectal cancer patients studied before surgery. Only 10 of these patients could be studied both pre- and postoperatively. 10 patients submitted to high dose preoperative chemoradiation were studied to evaluate the effect of this treatment on sexual function. Statistical analysis was performed by means of the two-tailed Student's t test for paired observations and k concordance test. Results 59.6% of patients operated reported sexual dysfunction, while this symptom occurred in 16.4% in the control group. Moreover, a significantly higher rate of alterations of the neurophysiological tests and longer mean latencies of the SR, PEPs, MEPs and SSRs were observed in the patients who had undergone resection. In the 10 patients studied both pre and post-surgery impotence occurred in 6 of them and the mean latencies of SSRs were longer after operation. In the 10 patients studied pre and post chemoradiation impotence occurred in 1 patient only, showing the mild effect of these treatments on sexual function. Conclusion Patients operated showed severe sexual dysfunctions. The neurophysiological test may be a useful tool to investigate this complication. The neurological damage could be monitored to decide the rehabilitation strategy.

  11. A randomized clinical trial of continuous aspiration of subglottic secretions in cardiac surgery patients. (United States)

    Kollef, M H; Skubas, N J; Sundt, T M


    To determine whether the application of continuous aspiration of subglottic secretions (CASS) is associated with a decreased incidence of ventilator-associated pneumonia (VAP). Prospective clinical trial. Cardiothoracic ICU (CTICU) of Barnes-Jewish Hospital, St. Louis, a university-affiliated teaching hospital. Three hundred forty-three patients undergoing cardiac surgery and requiring mechanical ventilation in the CTICU. Patients were assigned to receive either CASS, using a specially designed endotracheal tube (Hi-Lo Evac; Mallinckrodt Inc; Athlone, Ireland), or routine postoperative medical care without CASS. One hundred sixty patients were assigned to receive CASS, and 183 were assigned to receive routine postoperative medical care without CASS. The two groups were similar at the time of randomization with regard to demographic characteristics, surgical procedures performed, and severity of illness. Risk factors for the development of VAP were also similar during the study period for both treatment groups. VAP was seen in 8 patients (5.0%) receiving CASS and in 15 patients (8. 2%) receiving routine postoperative medical care without CASS (relative risk, 0.61%; 95% confidence interval, 0.27 to 1.40; p = 0. 238). Episodes of VAP occurred statistically later among patients receiving CASS ([mean +/- SD] 5.6 +/- 2.3 days) than among patients who did not receive CASS (2.9 +/- 1.2 days); (p = 0.006). No statistically significant differences for hospital mortality, overall duration of mechanical ventilation, lengths of stay in the hospital or CTICU, or acquired organ system derangements were found between the two treatment groups. No complications related to CASS were observed in the intervention group. Our findings suggest that CASS can be safely administered to patients undergoing cardiac surgery. The occurrence of VAP can be significantly delayed among patients undergoing cardiac surgery using this simple-to-apply technique.

    Thavikulwat, Alisa T; Fisher, Susan G; Thevenet-Morrison, Kelly; Pongtawigorn, Pornthep; Ramchandran, Rajeev S


    To evaluate the quality and efficacy of the Ban Phaeo Mobile Eye Clinic (BPMEC) model in providing cataract surgery to rural Thailand. Retrospective review of 4-week postoperative visual acuity (VA) of 7040 patients receiving unilateral cataract surgery at 75 sites from October 2008 to March 2011. BPMEC conducted screening, surgery, and follow-up at partnering local hospitals that otherwise do not offer eye care. The primary outcome was achievement of VA ≥20/70, which was secondarily analyzed by cataract extraction method (phacoemulsification, phaco, or extracapsular cataract extraction, ECCE) and intraocular lens (IOL) type (foldable acrylic or rigid polymethylmethacrylate). Preoperatively, 249 eyes (4%) had uncorrected VA ≥20/70. Four weeks postoperatively, 5957 (85%) had VA ≥20/70, 3288 (47%) had VA ≥20/40, and 69 (1%) were lost to follow-up. Phaco was performed in 6324 eyes (90%), 1581 (25%) receiving foldable IOLs. A total of 1403 eyes (89%) undergoing phaco with a foldable IOL had postoperative VA ≥20/70, compared to 4058 (85%) and 496 (69%) of those undergoing phaco with a rigid IOL (p < 0.05) and ECCE with a rigid IOL (p < 0.001), respectively. Overall, 37 eyes were left aphakic. Reported intraocular complications included zonular dehiscence (37 eyes), retained lens fragment (2 eyes), wound leakage (1 eye), and posterior capsule tear (1 eye). The 4-week uncorrected postoperative VAs met the World Health Organization's quality target of VA ≥20/70 for eyes undergoing phaco and were comparable to those published by an urban hospital in Bangkok.

  13. Development of preoperative planning software for transforaminal endoscopic surgery and the guidance for clinical applications. (United States)

    Chen, Xiaojun; Cheng, Jun; Gu, Xin; Sun, Yi; Politis, Constantinus


    Preoperative planning is of great importance for transforaminal endoscopic techniques applied in percutaneous endoscopic lumbar discectomy. In this study, a modular preoperative planning software for transforaminal endoscopic surgery was developed and demonstrated. The path searching method is based on collision detection, and the oriented bounding box was constructed for the anatomical models. Then, image reformatting algorithms were developed for multiplanar reconstruction which provides detailed anatomical information surrounding the virtual planned path. Finally, multithread technique was implemented to realize the steady-state condition of the software. A preoperative planning software for transforaminal endoscopic surgery (TE-Guider) was developed; seven cases of patients with symptomatic lumbar disc herniations were planned preoperatively using TE-Guider. The distances to the midlines and the direction of the optimal paths were exported, and each result was in line with the empirical value. TE-Guider provides an efficient and cost-effective way to search the ideal path and entry point for the puncture. However, more clinical cases will be conducted to demonstrate its feasibility and reliability.

    S. V. Mukhtarulina


    Full Text Available Objective: to study variants of retroperitoneal vascular structure and its clinical implications on retroperitoneal surgery in patients with cervical cancer IA–IIB stage.Materials and methods. 101 patients who underwent paraaortic and bilateral pelvic lymphadenectomy were included in this study. 10 patients of the first group with anomalies of inferior vena cava, renal arteries and veins, common iliac vein and ovarian vessels were compared with 91 patients of the second group without anomalies.Results. Variants of major retroperitoneal vascular structure were present in 10 (9.9 % patients. Supernumerary renal arteries and veins observed in 5 (4.9 % patients; retroaortic left renal vein type I and II – in 3 (3.0 % patients. Double vena cava inferior detected in 1 (1.0 % patient. Patients with variants of retroperitoneal vascular structures hadn’t vessel injury. There was no difference in intraoperative hemorrhage, transfusion red blood cell, rate of intraoperative hemoglobin and removed paraaortic lymph nodes between the groups. Risk factors for intraoperative bleeding in patients with cervical cancer, depending on the presence or absence of anomalies of retroperitoneal vessels had no significant difference.Conclusion. Despite the fact that the variants of retroperitoneal vascular structures are rare (9.9 %, the success of retroperitoneal surgery is associated with the knowledge of vascular variations which decrease serious, life-threatening complications.

  15. Hypnosis in the Perioperative Management of Breast Cancer Surgery: Clinical Benefits and Potential Implications (United States)

    Roelants, Fabienne; Pospiech, Audrey; Momeni, Mona; Watremez, Christine


    The aim of this review is to summarize data published on the use of perioperative hypnosis in patients undergoing breast cancer surgery (BCS). Indeed, the majority of BCS patients experience stress, anxiety, nausea, vomiting, and pain. Correct management of the perioperative period and surgical removal of the primary tumor are clearly essential but can affect patients on different levels and hence have a negative impact on oncological outcomes. This review examines the effect of clinical hypnosis performed during the perioperative period. Thanks to its specific properties and techniques allowing it to be used as complementary treatment preoperatively, hypnosis has an impact most notably on distress and postoperative pain. During surgery, hypnosis may be applied to limit immunosuppression, while, in the postoperative period, it can reduce pain, anxiety, and fatigue and improve wound healing. Moreover, hypnosis is inexpensive, an important consideration given current financial concerns in healthcare. Of course, large randomized prospective studies are now needed to confirm the observed advantages of hypnosis in the field of oncology. PMID:27635132

  16. Clinical Prediction of Deeply Infiltrating Endometriosis before Surgery: Is It Feasible? A Review of the Literature

    Directory of Open Access Journals (Sweden)

    Márcia Mendonça Carneiro


    Full Text Available Background. Endometriosis is a chronic benign gynecologic disease that can cause pelvic pain and infertility affecting almost 10% of reproductive-age women. Deeply infiltrating endometriosis (DIE is a specific entity responsible for painful symptoms which are related to the anatomic location of the lesions. Definitive diagnosis requires surgery, and histological confirmation is advisable. The aim of this paper is to review the current literature regarding the possibility of diagnosing DIE accurately before surgery. Despite its low sensitivity and specificity, vaginal examination and evaluation of specific symptoms should not be completely omitted as a basic diagnostic tool in detecting endometriosis and planning further therapeutic interventions. Recently, transvaginal ultrasound (TVUS has been reported as an excellent tool to diagnose DIE lesions in different locations (rectovaginal septum, retrocervical and paracervical areas, rectum and sigmoid, and vesical wall with good accuracy. Conclusion. There are neither sufficiently sensitive and specific signs and symptoms nor diagnostic tests for the clinical diagnosis of DIE, resulting in a great delay between onset of symptoms and diagnosis. Digital examination, in addition to TVS, may help to gain better understanding of the anatomical extent and dimension of DIE which is of crucial importance in defining the best surgical approach.

    Nishimura, Reiki; Nagao, Kazuharu; Miyayama, Haruhiko [Kumamoto City Hospital (Japan)] [and others


    Significant risk factors for recurrence of breast cancer after breast-conserving therapy, which has become a standard treatment for breast cancer, are positive surgical margins and the failure to perform radiation therapy. In this study, we evaluated the clinical significance of radiation therapy after primary surgery or breast recurrence. In 344 cases of breast-conserving surgery, disease recurred in 43 cases (12.5%), which were classified as follows: 17 cases of breast recurrence, 13 cases of breast and distant metastasis, and 13 cases of distant metastasis. Sixty-two patients (16.7%) received radiation therapy. A positive surgical margin and younger age were significant risk factors for breast recurrence in patients not receiving postoperative radiation therapy but not in patients receiving radiation therapy. Radiation therapy may be beneficial for younger patients with positive surgical margins. Furthermore, radiation therapy after recurrence was effective in the cases not treated with postoperative radiation but not in cases with inflammatory recurrence. Patients with breast recurrence alone had significantly higher survival rates than did patients with distant metastases regardless of breast recurrence. These findings suggest that the adaptation criteria of radiation therapy for local control must be clarified. (author)

    Full Text Available South Africa bears the greatest burden of HIV infection globally with the most infected people living in KwaZulu-Natal (KZN. Decentralised medical care for HIV positive patients and antiretroviral therapy (ART delivery to primary health care facilities were proposed nationally to achieve adequate ART coverage for patients in need of treatment. This study described the HIV positive patients who accessed medical care and were initiated on ART at two existing government Primary Health Care (PHC clinics with no added donor support, in Ilembe, KZN. This was an observational descriptive study of ART initiation from 01 April 2008 to 30 April 2009. Data were collected from clinical records kept on site. HIV Testing and the pre-ART programmes which consisted of medical care prior to ART initiation are briefly described. Socio-economic, demographic and clinical characteristics of patients who were initiated on ART were sampled and described. A minority (2.95% of the study population tested for HIV of which 36.0%tested positive. Majority (60.0% of patients who joined the pre-ART programme care did not return. The ART sample consisted of 375 patients of whom 65.0%were women, 85.9%were unmarried, 61.6%were unemployed and 50.4%had a secondary level of education. Tuberculosis (TB prevalence and incidence at ART initiation were 22.1%and 14.7%respectively. The prevalence of Syphilis and Hepatitis B co-infections were 13.1%and 8.6 %respectively. Two thirds of female patients (66.4% received a Pap smear result of which the majority (62.3% were abnormal. Uptake for HIV testing followed by relevant CD4 testing was poor. High TB, Hepatitis B and Syphilis co-infection was noted amongst patients initiated on ART. Cervical cancer screening must be intensified. Although ART initiation with no added external resources was successful, record keeping was suboptimal.

    Laparoscopic rectal resection is technically challenging, with outcomes dependent upon technical performance. No robust objective assessment tool exists for laparoscopic rectal resection surgery. This study aimed to investigate the application of the objective clinical human reliability analysis (OCHRA) technique for assessing technical performance of laparoscopic rectal surgery and explore the validity and reliability of this technique. Laparoscopic rectal cancer resection operations were described in the format of a hierarchical task analysis. Potential technical errors were defined. The OCHRA technique was used to identify technical errors enacted in videos of twenty consecutive laparoscopic rectal cancer resection operations from a single site. The procedural task, spatial location, and circumstances of all identified errors were logged. Clinical validity was assessed through correlation with clinical outcomes; reliability was assessed by test-retest. A total of 335 execution errors identified, with a median 15 per operation. More errors were observed during pelvic tasks compared with abdominal tasks (p technical performance of laparoscopic rectal surgery.

  2. Predictors, Prognosis, and Management of New Clinically Important Atrial Fibrillation After Noncardiac Surgery: A Prospective Cohort Study. (United States)

    Alonso-Coello, Pablo; Cook, Deborah; Xu, Shou Chun; Sigamani, Alben; Berwanger, Otavio; Sivakumaran, Soori; Yang, Homer; Xavier, Denis; Martinez, Luz Ximena; Ibarra, Pedro; Rao-Melacini, Purnima; Pogue, Janice; Zarnke, Kelly; Paniagua, Pilar; Ostrander, Jack; Yusuf, Salim; Devereaux, P J


    Despite the frequency of new clinically important atrial fibrillation (AF) after noncardiac surgery and its increased association with the risk of stroke at 30 days, there are limited data informing their prediction, association with outcomes, and management. We used the data from the PeriOperative ISchemic Evaluation trial to determine, in patients undergoing noncardiac surgery, the association of new clinically important AF with 30-day outcomes, and to assess management of these patients. We also aimed to derive a clinical prediction rule for new clinically important AF in this population. We defined new clinically important AF as new AF that resulted in symptoms or required treatment. We recorded an electrocardiogram 6 to 12 hours postoperatively and on the 1st, 2nd, and 30th days after surgery. A total of 211 (2.5% [8351 patients]; 95% confidence interval, 2.2%-2.9%) patients developed new clinically important AF within 30 days of randomization (8140 did not develop new AF). AF was independently associated with an increased length of hospital stay by 6.0 days (95% confidence interval, 3.5-8.5 days) and vascular complications (eg, stroke or congestive heart failure). The usage of an oral anticoagulant at the time of hospital discharge among patients with new AF and a CHADS2 score of 0, 1, 2, 3, and ≥4 was 6.9%, 10.2%, 23.0%, 9.4%, and 33.3%, respectively. Two independent predictors of patients developing new clinically important AF were identified (ie, age and surgery). The prediction rule included the following factors and assigned weights: age ≥85 years (4 points), age 75 to 84 years (3 points), age 65 to 74 years (2 points), intrathoracic surgery (3 points), major vascular surgery (2 points), and intra-abdominal surgery (1 point). The incidence of new AF based on scores of 0 to 1, 2, 3 to 4, and 5 to 6 was 0.5%, 1.0%, 3.1%, and 5.3%, respectively. Age and surgery are independent predictors of new clinically important AF in the perioperative setting. A

    A retrospective study. To report midterm clinical and radiographic results of Graf artificial ligament stabilization in the treatment of degenerative spondylolisthesis and to evaluate the role of this procedure and its surgical indications for surgical success. Nonfusion surgeries including artificial disc replacement and ligamentoplasty are increasingly gaining interest to avoid adverse effects of spinal fusion. Sixty-four consecutive patients with degenerative spondylolisthesis underwent artificial ligament stabilization. Surgical indication was symptomatic degenerative spondylolisthesis with adjacent segment pathologies (6.3%). One patient (1.6%) underwent consequent spinal arthrodesis at the ligamentoplasty level. Artificial ligament stabilization did not improve the vertebral slip but maintained lordosis and preserved segmental motion in 80% of patients. This procedure is an effective alternative to spinal arthrodesis in the treatment of symptomatic degenerative spondylolisthesis (Grade I) with minimal disc space narrowing and coronal facet tropism.

  4. Assessing transgastric Natural Orifice Transluminal Endoscopic Surgery prior to clinical implementation

    DEFF Research Database (Denmark)

    Donatsky, Anders Meller


    The objective was to investigate whether transgastric Natural Orifice Transluminal Endoscopic Surgery (NOTES) could be implemented safely in clinical practice. The experimental studies proved ultrasonography guided access through the stomach to be feasible and safe without iatrogenic complications...... visualisation of anatomical structures of interest in the diagnostics and staging of upper gastrointestinal cancers. Another problem with TG NOTES is the risk of intra-abdominal infections. Using a multimodal decontamination regimen reduced the rate of intra-abdominal pathology, but the risk of intra......-abdominal abscess formation as a result of contamination from the access route was still present. To reduce this contamination, mouthwash with chlorhexidine was effective in a human randomised study. The same study also found significant higher bacterial load in the stomach of patients using proton pump inhibitor...

    Full Text Available Abstract Background Clinical officers perform much of major emergency surgery in Malawi, in the absence of medical officers. The aim of this study was to validate the advantages and disadvantages of delegation of major obstetric surgery to non-doctors. Methods During a three month period, data from 2131 consecutive obstetric surgeries in 38 district hospitals in Malawi were collected prospectively. The interventions included caesarean sections alone and those that were combined with other interventions such as subtotal and total hysterectomy repair of uterine rupture and tubal ligation. All these surgeries were conducted either by clinical officers or by medical officers. Results During the study period, clinical officers performed 90% of all straight caesarean sections, 70% of those combined with subtotal hysterectomy, 60% of those combined with total hysterectomy and 89% of those combined with repair of uterine rupture. A comparable profile of patients was operated on by clinical officers and medical officers, respectively. Postoperative outcomes were almost identical in the two groups in terms of maternal general condition – both immediately and 24 hours postoperatively – and regarding occurrence of pyrexia, wound infection, wound dehiscence, need for re-operation, neonatal outcome or maternal death. Conclusion Clinical officers perform the bulk of emergency obstetric operations at district hospitals in Malawi. The postoperative outcomes of their procedures are comparable to those of medical officers. Clinical officers constitute a crucial component of the health care team in Malawi for saving maternal and neonatal lives given the scarcity of physicians.

  6. Clinical implementation of intraoperative cone-beam CT in head and neck surgery (United States)

    Daly, M. J.; Chan, H.; Nithiananthan, S.; Qiu, J.; Barker, E.; Bachar, G.; Dixon, B. J.; Irish, J. C.; Siewerdsen, J. H.


    A prototype mobile C-arm for cone-beam CT (CBCT) has been translated to a prospective clinical trial in head and neck surgery. The flat-panel CBCT C-arm was developed in collaboration with Siemens Healthcare, and demonstrates both sub-mm spatial resolution and soft-tissue visibility at low radiation dose (e.g., <1/5th of a typical diagnostic head CT). CBCT images are available ~15 seconds after scan completion (~1 min acquisition) and reviewed at bedside using custom 3D visualization software based on the open-source Image-Guided Surgery Toolkit (IGSTK). The CBCT C-arm has been successfully deployed in 15 head and neck cases and streamlined into the surgical environment using human factors engineering methods and expert feedback from surgeons, nurses, and anesthetists. Intraoperative imaging is implemented in a manner that maintains operating field sterility, reduces image artifacts (e.g., carbon fiber OR table) and minimizes radiation exposure. Image reviews conducted with surgical staff indicate bony detail and soft-tissue visualization sufficient for intraoperative guidance, with additional artifact management (e.g., metal, scatter) promising further improvements. Clinical trial deployment suggests a role for intraoperative CBCT in guiding complex head and neck surgical tasks, including planning mandible and maxilla resection margins, guiding subcranial and endonasal approaches to skull base tumours, and verifying maxillofacial reconstruction alignment. Ongoing translational research into complimentary image-guidance subsystems include novel methods for real-time tool tracking, fusion of endoscopic video and CBCT, and deformable registration of preoperative volumes and planning contours with intraoperative CBCT.

  7. Identification of Best Practices for Resident Aesthetic Clinics in Plastic Surgery Training: The ACAPS National Survey (United States)

    Wu, Cindy; Bentz, Michael L.; Redett, Richard J.; Shack, R. Bruce; David, Lisa R.; Taub, Peter J.; Janis, Jeffrey E.


    Introduction: Resident aesthetic clinics (RACs) have demonstrated good outcomes and acceptable patient satisfaction, but few studies have evaluated their educational, financial, or medicolegal components. We sought to determine RAC best practices. Methods: We surveyed American Council of Academic Plastic Surgeon members (n = 399), focusing on operational details, resident supervision, patient safety, medicolegal history, financial viability, and research opportunities. Of the 96 respondents, 63 reported having a RAC, and 56% of plastic surgery residency program directors responded. Results: RACs averaged 243 patient encounters and 53.9 procedures annually, having been in existence for 19.6 years (mean). Full-time faculty (73%) supervised chief residents (84%) in all aspects of care (65%). Of the 63 RACs, 45 were accredited, 40 had licensed procedural suites, 28 had inclusion/exclusion criteria, and 31 used anesthesiologists. Seventeen had overnight capability, and 17 had a Life Safety Plan. No cases of malignant hyperthermia occurred, but 1 facility death was reported. Sixteen RACs had been involved in a lawsuit, and 33 respondents reported financial viability of the RACs. Net revenue was transferred to both the residents’ educational fund (41%) and divisional/departmental overhead (37%). Quality measures included case logs (78%), morbidity/mortality conference (62%), resident surveys (52%), and patient satisfaction scores (46%). Of 63 respondents, 14 have presented or published RAC-specific research; 80 of 96 of those who were surveyed believed RACs enhanced education. Conclusions: RACs are an important component of plastic surgery education. Most clinics are financially viable but carry high malpractice risk and consume significant resources. Best practices, to maximize patient safety and optimize resident education, include use of accredited procedural rooms and direct faculty supervision of all components of care. PMID:26146599

    The number of obese pediatric patients requiring anesthesia is rapidly increasing. Although fentanyl is a commonly used narcotic during surgery, there are no pharmacokinetic (PK) data available for optimal dosing of fentanyl in adolescents with clinically severe obesity. An institutional review board-approved exploratory pilot study was conducted in six adolescents aged 14-19 years undergoing bariatric surgery. Mean total body weight (TBW) and mean BMI were 137.4 ± 14.3 kg and 49.6 ± 6.4 kg/m 2 (99.5th BMI percentile), respectively. Fentanyl was administered intravenously for intraoperative analgesia based on ideal body weight per standard of care. PK blood samples were drawn over a 24-h post-dose period. Fentanyl PK parameters were calculated by non-compartmental analysis. Mean fentanyl AUC 0-∞ was 1.5 ± 0.5 h·ng/mL. Systemic clearance of fentanyl was 1522 ± 310 mL/min and 11.2 ± 2.6 mL/min·kg TBW. Volume of distribution was 635 ± 282 L and 4.7 ± 2.1 L/kg TBW. While absolute clearance was increased, absolute volume of distribution was comparable to previously established adult values. These results suggest that fentanyl clearance is enhanced in adolescents with clinically severe obesity while volume of distribution is comparable to previously published studies. NCT01955993 (

    Full Text Available Objective: In patients receiving bone marrow transplantation (BMT, their mucosa becomes altered and sclerotic changes in the female external genital organs occur. Although a few studies have specifically addressed vulvar and vaginal graft versus host disease (VVGvHD and its repercussions on the sexual health and quality of life of patients, VVGvHD can be overlooked by health practitioners. The objective of the study is to describe the initiation of a health care clinic specializing in VVGvHD in a general tertiary hospital. Methods: A VVGvHD clinic was founded as a part of BMT daycare in a joint initiative of the nursing staff and the medical director of the department and a gynecologist specializing in vulva and vaginal disease. Patients were assessed for vulvovaginal symptoms, such as dryness, burning, itching, pain to touch, pain during intercourse, and dysuria. These patients might be subsequently referred to the VVGvHD clinic according to their needs assessed by daycare nurses. Treatment guidelines were developed by the specialist gynecologist. Results: A total of 81 women aged 2–66 years (median age = 38 years visited the clinic from 2009 to 2015. Of these women, 70 received an allogeneic transplant and 11 underwent autologous transplantation before consultation in our clinic. VVGvHD was detected in 54% of the patients. Conclusions: The VVGvHD clinic was developed to fulfill the specific needs of female patients who underwent BMT. The pioneer clinic was founded as a joint effort of the multidisciplinary team. Evidence supporting the optimum treatment for this condition is insufficient. This was the main reason for performing this study to explore the clinic that was newly based in Israel. VVGvHD may be a fluctuating condition with frequent deterioration and improvement. Therefore, regular clinical examinations are necessary.

    Full Text Available Introduction. Hallux rigidus is observed in approximately 2.5% of the adult population. Until now neither a unified classification of hallux rigidus appears to exist nor any clear principles to choose the surgical method. The variety of clinical and radiological signs explains the difficulties in establishing a comprehensive classification system and in selection of the criteria for surgical procedure. There are few published reports about hallux rigidus percutaneous surgical treatment. Existing papers are dedicated to a limited number of percutaneous techniques.The purpose of this study was to evaluate the efficacy of percutaneous techniques for surgical treatment of the first metatarsophalangeal joint osteoarthritis; to specify factors determining the choice of procedure; to develop a grading system of the hallux rigidus severity which will help in selection of surgery. Materials and methods. Based on 156 surgeries (107 patients the author demonstrated the possibilities of percutaneous techniques in the surgical treatment of hallux rigidus of different stages as well as provided a brief description of used surgical techniques.Results. The mean age of patients was 48.8 years (ranged from 18 to 73. The mean follow-up was 7 months (ranged from 3 to 54. At the specified time the treatment outcomes of 103 patients (150 feet were analyzed. Mean hospital stay was 0.78 days (ranged from 0 to 1. No infectious or wound-healing problems were observed. Overall, the patients were completely satisfied with the outcomes of 89 surgical treatment, qualified satisfaction was reported with patients in respect of outcomes of 57 surgeries. Four unsatisfactory outcomes were observed. The role of the relatively long first metatarsal in the development of hallux rigidus was confirmed. Conclusion. Percutaneous techniques provide successful treatment for all stages of hallux rigidus. The choice of a specific surgical technique may be challenging and requires

    D'haese, Jan; Vervaeke, Stijn; Verbanck, Nathalie; De Bruyn, Hugo


    The number of clinical reports giving detailed information on clinical outcomes with guided surgery is rather scarce despite its large-scale introduction over the last decade. The aim of this report was to determine implant survival and success in terms of peri-implant bone loss and evaluate whether smoking affects the outcome. A total of 26 cases with a partially or totally edentulous maxilla were selected for implant treatment using the Facilitate software system (Astra Tech). In totally edentulous cases, six fluoride-modified OsseoSpeed implants (Astra Tech) were inserted. Immediately after implantation, abutments were screwed onto the implants. Within 8 hours, a provisional screw-retained fiber-reinforced acrylic fixed dental prosthesis was screwed on the abutments. For the partial cases, the surgical guide rested on the remaining teeth and implants were not immediately loaded. In total 13 out of 114 implants were lost within 12 months after surgery, resulting in 88.6% survival at 1 year. Twelve of those failures occurred in smokers, leading to 69.2% implant survival compared to 98.7% in nonsmokers. Implants were lost in 7 out of 26 (26.9%) patients; only 1 out of 17 nonsmokers (5.9%) compared to 6 out of 9 (66.7%) smokers lost one or more implants. In total, 38.5% of the subjects with a full immediately loaded fixed dental prosthesis experienced implant failures compared with 15.4% of the partially delayed loaded cases. The overall mean bone loss based on all implants was 0.47 mm (SD, 0.94). Mean bone loss was 0.36 mm for nonsmokers and 0.62 mm for smokers. On the basis of the current case control study, it is tempting to suggest that smoking is an exclusion factor when placing implants using stereolithographic guided surgery in conjunction with immediate loading. There is still not enough scientific evidence to show if this method is as safe and predictable as the traditional method.

  13. Recent advances in bariatric/metabolic surgery: appraisal of clinical evidence. (United States)

    Lee, Wei-Jei; Almulaifi, Abdullah


    Obesity and associated type 2 diabetes mellitus (T2DM) are becoming a serious medical issue worldwide. Bariatric surgery has been shown to be the most effective and durable therapy for the treatment of morbid obese patients. Increasing data indicates bariatric surgery as metabolic surgery is an effective and novel therapy for not well controlled obese T2DM patients. The review of recent developments in bariatric/metabolic surgery covers 4 major fields. 1) Improvement of safety: recent advances in laparoscopic/metabolic surgery has made this minimal invasive surgery more than ten times safer than a decade ago. The safety profile of laparoscopic/metabolic surgery is compatible with that of laparoscopic cholecystectomy now. 2) New bariatric/metabolic surgery: laparoscopic sleeve gastrectomy (LSG) is becoming the leading bariatric surgery because of its simplicity and efficacy. Other new procedures, such as gastric plication, banded plication, single anastomosis (mini) gastric bypass and Duodeno-jejunal bypass with sleeve gastrectomy have all been accepted as treatment modalities for bariatric/metabolic surgery. 3) Mechanism of bariatric/metabolic surgery: Restriction is the most important mechanism for bariatric surgery. Weight regain after bariatric surgery is usually associated with loss of restriction. Recent studies demonstrated that gut hormone, microbiota and bile acid changes after bariatric surgery may play an important role in durable weight loss as well as in T2DM remission. However, weight loss is still the cornerstone of T2DM remission after metabolic surgery. 4) PATIENT SELECTION: patients who may benefit most from bariatric surgery was found to be patients with insulin resistance. For Asian T2DM patients, the indication of metabolic surgery has been set to those with not well controlled (HbA1c > 7.5%) disease and with their BMI > 27.5 Kg/m(2). A novel diabetes surgical score, ABCD score, is a simple system for predicting the success of surgical therapy

  14. Endocrine and nutritional management of the post-bariatric surgery patient: an Endocrine Society Clinical Practice Guideline. (United States)

    Heber, David; Greenway, Frank L; Kaplan, Lee M; Livingston, Edward; Salvador, Javier; Still, Christopher


    We sought to provide guidelines for the nutritional and endocrine management of adults after bariatric surgery, including those with diabetes mellitus. The focus is on the immediate postoperative period and long-term management to prevent complications, weight regain, and progression of obesity-associated comorbidities. The treatment of specific disorders is only summarized. The Task Force was composed of a chair, five additional experts, a methodologist, and a medical writer. It received no corporate funding or remuneration. Bariatric surgery is not a guarantee of successful weight loss and maintenance. Increasingly, patients regain weight, especially those undergoing restrictive surgeries such as laparoscopic banding rather than malabsorptive surgeries such as Roux-en-Y bypass. Active nutritional patient education and clinical management to prevent and detect nutritional deficiencies are recommended for all patients undergoing bariatric surgery. Management of potential nutritional deficiencies is particularly important for patients undergoing malabsorptive procedures, and strategies should be employed to compensate for food intolerance in patients who have had a malabsorptive procedure to reduce the risk for clinically important nutritional deficiencies. To enhance the transition to life after bariatric surgery and to prevent weight regain and nutritional complications, all patients should receive care from a multidisciplinary team including an experienced primary care physician, endocrinologist, or gastroenterologist and consider enrolling postoperatively in a comprehensive program for nutrition and lifestyle management. Future research should address the effectiveness of intensive postoperative nutritional and endocrine care in reducing morbidity and mortality from obesity-associated chronic diseases.

    Ann Green

    Full Text Available INTRODUCTION: To combat the AIDS epidemic and increase HIV treatment access, the South African government implemented a nurse-based, doctor-supported model of care that decentralizes administration of antiretroviral treatment (ART for HIV positive patients through nurse initiated and managed ART. Médecins Sans Frontières (MSF implemented a mentorship programme to ensure successful task-shifting, subsequently assessing the quality of clinical care provided by nurses. METHODS: A before-after cross-sectional study was conducted on nurses completing the mentorship programme in Khayelitsha, South Africa, from February 2011-September 2012. Routine clinical data from 229 patient folders and 21 self-assessment questionnaires was collected to determine the number of patients initiated on ART by nurses; quality of ART management before-after mentorship; patient characteristics for doctor and nurse ART initiations; and nurse self-assessments after mentorship. RESULTS: Twenty one nurses were authorized by one nurse mentor with one part-time medical officer's support, resulting in nurses initiating 77% of ART eligible patients. Improvements in ART management were found for drawing required bloods (91% vs 99%, p = 0.03, assessing adherence (50% vs 78%, p<0.001 and WHO staging (63% vs 91%, p<0.001. Nurse ART initiation indicators were successfully completed at 95-100% for 11 of 16 indicators: clinical presentation; patient weight; baseline blood work (CD4, creatinine, haemoglobin; STI screening; WHO stage, correlating medical history; medications prescribed appropriately; ART start date; and documented return date. Doctors initiated more patients with TB/HIV co-infection and WHO Stage 3 and 4 disease than nurses. Nurse confidence improved for managing HIV-infected children and pregnant women, blood result interpretation and long-term side effects. CONCLUSIONS: Implementation of a clinical mentorship programme in Khayelitsha led to nurse initiation of a

    Daniele Bernardeschi


    Full Text Available Objective. To evaluate the cutaneous and the inner ear tolerance of bioactive glass S53P4 when used in the mastoid and epitympanic obliteration for chronic otitis surgery. Material and Methods. Forty-one cases have been included in this prospective study. Cutaneous tolerance was clinically evaluated 1 week, 1 month, and 3 months after surgery with a physical examination of the retroauricular and external auditory canal (EAC skin and the presence of otalgia; the inner ear tolerance was assessed by bone-conduction hearing threshold 1 day after surgery and by the presence of vertigo or imbalance. Results. All surgeries but 1 were uneventful: all patients maintained the preoperative bone-conduction hearing threshold except for one case in which the round window membrane was opened during the dissection of the cholesteatoma in the hypotympanum and this led to a dead ear. No dizziness or vertigo was reported. Three months after surgery, healing was achieved in all cases with a healthy painless skin. No cases of revision surgery for removal of the granules occurred in this study. Conclusion. The bioactive glass S53P4 is a well-tolerated biomaterial for primary or revision chronic otitis surgery, as shown by the local skin reaction which lasted less than 3 months and by the absence of labyrinthine complications.

  17. Initial impact of a dedicated postgraduate laparoscopic mini-residency on clinical practice patterns. (United States)

    Chou, David S; Abdelshehid, Corollos S; Uribe, Carlos A; Khonsari, Sephir S; Eichel, Louis; Boker, John R; Shanberg, Allan M; Ahlering, Thomas E; Clayman, Ralph V; McDougall, Elspeth M


    Laparoscopic surgical techniques are difficult to master, especially for surgeons who did not receive this type of training during their residencies. We have established a 5-day mentor-preceptor- proctor-guided postgraduate "mini-residency" (M-R) experience in minimally invasive surgery. The initial results from the first 16 participants in the laparoscopic M-R modules are presented. On the first and the last day of the M-R, all participants underwent surgical skills testing using an open-surgery, standard laparoscopic, and robot-assisted laparoscopic format. A written examination was also administered on the last day. The influence of M-R on the participants' practice pattern was then assessed by a follow-up questionnaire survey 1 to 7 months after their attendance. Data from the first 16 participants were analyzed. Of note, the score was significantly improved for only one of the four tested laparoscopic skills (i.e., threading a suture through loops). Nonetheless, on the follow-up survey, of the 15 respondents, two laparoscopically naïve participants had performed laparoscopic nephrectomy, and of the eight participants who had prior renal-ablative laparoscopic experience, four had performed advanced reconstructive laparoscopic cases. A 5-day dedicated postgraduate M-R in laparoscopy appears to be helpful for urologists wishing to incorporate this surgical approach into their practices. The "take rate" among participants is initially at the 40% level, similar to what has been previously reported after a 1 to 2-day hands-on didactic laparoscopy course.

  18. Factors influencing radiographic and clinical outcomes in adult scoliosis surgery: a study of 448 European patients. (United States)

    Koller, Heiko; Pfanz, Conny; Meier, Oliver; Hitzl, Wolfgang; Mayer, Michael; Bullmann, Viola; Schulte, Tobias L


    In adult scoliosis surgery (AS) delineation of risk factors contributing to failure is important to improve patient care. Treatment goals include deformity correction resulting in a balanced spine and horizontal lowest instrumented vertebra (LIV) in fusions not ending at S1. Therefore, the study objectives were to determine predictors for deformity correction, complications, revision surgery, and outcomes as well as to determine predictors of postoperative evolution of the LIV-take-off angle (LIV-TO) and symptomatic adjacent segment disease (ASD). The authors performed a retrospective analysis of 448 patients who had AS surgery. Patients' age averaged 51 years, BMI 26, and follow-up of 40 months. According to the SRS adult scoliosis classification, 51 % of patients had major lumbar curves, 24 % each with single thoracic or double major curves. 54 % of patients had stable vertebra at L5 and 34 % of patients had fusion to S1. The mean number of posterior fusion levels was eight and implant density 73 %. Among standard radiographic measures of deformity the LIV-TO was assessed on neutral and bending/traction-films (bLIV-TO). Clinical outcomes were assessed in 145 patients with degenerative-type AS using validated measures (ODI, COMI and SF-36). Prediction analysis was conducted with stepwise multiple regression analyses. Preoperative thoracic curve (TC) was 53° and 33° at follow-up. Preoperative lumbar curve (LC) was 43° and 24° at follow-up. Curve flexibility was low (TC 34 %/LC 38 %). TC-correction (38 %) was predicted by preoperative TC (r = 0.9) and TC-flexibility (r = 0.8). LC-correction (50 %) was predicted by preoperative LC (r = 0.8), LC-flexibility (r = 0.8) and screw density (r = 0.7). Preoperative LIV-TO was 18.2° and at follow-up 9.4° (p < 0.01). 20 % of patients had a non-union (18 % at L5-S1). The risk for non-union at L5-S1 increased with age (p = 0.04), low screw density (p = 0.03), and postoperative sagittal imbalance [(T9-tilt (p = 0.01), C7

    A prospective, longitudinal study was conducted to examine Big Five personality characteristics as predictors of adherence to clinic-based rehabilitation activities following anterior cruciate ligament (ACL) reconstruction surgery. Participants (72 men, 36 women) completed a questionnaire assessing Big Five personality dimensions prior to surgery. For the first 7 weeks after surgery, participants' rehabilitation session attendance was recorded and rehabilitation professionals rated participants' adherence during rehabilitation sessions.. Results of multiple regression analyses indicated that the 5 personality factors explained 11 percent of the variance in attendance and 17 percent of the variance in adherence ratings, that agreeableness was a significant positive predictor of attendance, and that conscientiousness and openness to experience were significant positive predictors of adherence ratings. As a potential contributor to adherence, personality warrants consideration when implementing rehabilitation programs after ACL surgery.

  20. Recent advances in bariatric/metabolic surgery: appraisal of clinical evidence


    Lee, Wei-Jei; Almulaifi, Abdullah


    Abstract Obesity and associated type 2 diabetes mellitus (T2DM) are becoming a serious medical issue worldwide. Bariatric surgery has been shown to be the most effective and durable therapy for the treatment of morbid obese patients. Increasing data indicates bariatric surgery as metabolic surgery is an effective and novel therapy for not well controlled obese T2DM patients. The review of recent developments in bariatric/metabolic surgery covers 4 major fields. 1) Improvement of safety: recen...

  1. Retrospective analysis of patients clinical manifestations before and after pheochromocytoma surgery. (United States)

    Balazovjech, I; Davidova, H; Breza, J


    A retrospective analysis of presurgical clinical picture and blood pressures of 34 patients with histologically verified pheochromocytoma. Assessment of clinical state, blood pressure and prognosis in the course of patients control hospitalizations from 2001 to 2002. The study was designed as a synoptic one, based on a retrospective analysis of 34 patients records with histologically verified pheochromocytoma (26 women and 8 men). Our assessments of clinical symptomatology, maximum paroxysmal hypertension values, average blood pressure values in patients with persistent arterial hypertension, arterial hypertension grade and circadian index were based on patients records. Patients epinephrectomies were followed during their control hospitalizations to assess their clinical state. Their blood pressures were evaluated by means of their circadian monitoring. From the 34 patients, 21 were diagnosed with solitary pheochromocytomas. The circadian index persistence analysis prior to the surgery was associated with circadian blood pressure monitoring in 21 patients. It was lost in 57% of patients. During their control hospitalization as many as 82% of patients preserved their circadian blood pressure variability with a more than 10% decrease in the night time, 5 patients did not preserve their circadian blood pressure variability. Seven from the original 34 patients died: Three of them died from their primary disease, one 63-year old man died from shock following tumour extirpation. The death of other 3 patients was not associated with their primary disease. Long-lasting survival of patients with pheochromocytoma after surgical treatment--except for those with malignant disease--was demonstrated. Although our assessment of the resulting treatment effects was positive, a long-term follow-up is inevitable because of a difficult pathologic-anatomical verification of the malignant nature of the disease as well as of the risk of tumour relapse assessment.

However, the positive diagnostic value of this noninvasive test in clinically suspected pulmonary embolism is not very high (10%–18%. Since thromboembolic risks increase considerably in hospitalized patients with advanced age, this study aims to determine the importance of lower extremity venous color flow duplex scan in this particular subgroup of patients with clinically suspected pulmonary embolism. The effects of clinical presentation and risk factors on the results of duplex scan have been also studied. Methods: Between July 2007 and January 2010, 95 consecutive Lebanese geriatric ($60 years of age inpatients with clinically suspected pulmonary embolism assessed in an academic tertiary-care center for complete lower extremity venous color flow duplex scan were retrospectively reviewed. Age varied between 60 and 96 years (mean, 79.9 years. Forty patients were males and 55 females. Absence of compressibility was the most important criteria for detecting acute venous thrombosis. Results: Out of 95 patients, 33 patients (34.7% were diagnosed with recent deep venous thrombosis of lower extremities (14 proximal and 19 distal using complete venous ultrasound. Nine of these 33 patients (27.2% had a history of venous thromboembolism and eleven (33.3% presented with edema of lower

    Counts, J M


    This article addresses the importance of public health, hospital, and clinical laboratories in the role of patient care, disease prevention, and surveillance. It also focuses on the coordination and planning that needs to take place between these institutions in order to develop a more cost-effective and responsive laboratory delivery system. The Washington Clinical Laboratory Initiative is an innovative state initiative illustrating that coordinated and integrated strategic planning of public and private sector laboratories can be accomplished within a state. It also has increased interaction, collaboration, and communication between health practitioners, health plans, hospitals, laboratories, government agencies, and academicians. This accomplishment has enabled the establishment of public policy concerning laboratory reimbursement and development of standards of laboratory practice.

  4. Cauda equina syndrome as the initial presenting clinical feature of medulloblastoma: a case report

    Al-Otaibi Faisal


    Full Text Available Abstract Introduction Medulloblastoma is one of the most common pediatric brain malignancies. The usual presenting clinical features are related to posterior fossa syndrome or/and hydrocephalus. Cauda equina syndrome is a very rare presentation for this disease. Case presentation We describe the case of a three-year-old boy with cauda equina syndrome as the initial presenting clinical feature for medulloblastoma. He was initially diagnosed as having a spinal tumor by magnetic resonance imaging scan. Subsequently, a cranial magnetic resonance imaging scan revealed a posterior fossa tumor with features of dissemination. He had substantial improvement after treatment. This case report is complemented by a literature review related to this unusual presentation. Conclusions Medulloblastoma primarily presenting with cauda equina syndrome is very rare. However, spinal drop metastasis should be considered in the pediatric age group to avoid suboptimal management.

  5. [Emotional stress as a clinical model to study the pathogenesis of the initial phase of the general adaptation syndrome]. (United States)

    Anikhovskaya, I A; Dvoenosov, V G; Zhdanov, R I; Koubatiev, A A; Mayskiy, I A; Markelova, M M; Meshkov, M V; Oparina, O N; Salakhov, I M; Yakovlev, M Yu


    General adaptation syndrome (GAS), the basis of the development of which is stress phenomenon, is an essential component of the pathogenesis of many diseases and syndromes. However, the patho genesis of GAS hitherto is considered exclusively from the endocrinological viewpoint. This relates primarily to the initial phase of the GAS, a clinical model for the study of which may be psycho-emotional stress (PES), which we studied using three groups of volunteers. The first one consists of 25 students who were waiting for unaccustomed physical activity (17 men) and play debut on the stage (8 women). The second group consists of 48 children (2-14 years) who expected for "planned" surgery. The third group of volunteers is made up of 80 students (41 women and 39 men) during the first exam. The concentration of cortisol, endotoxin (ET), the activity of antiendotoxin immunity (AEI) and the haemostatic system parameters were determined in the blood serum of volunteers in various combinations. We found laboratory evidence for PES at 92% of students of the first group, 58% of children of the second one and in 21% of students of the third group of volunteers (mostly women). The concentration of ET increased at 13 (52%) volunteers of the first group with a significant increase of average indicators in the whole group (from 0.84 ± 0.06 to 1.19 ± 0.04 EU/ml). At children of the second group, the average concentration of ET increased even more significantly (from 0.42 ± 0.02 to 1.63 ± 0.11 EU/ml), which was accompanied by the activation of the hemostasis system. A degree of the activation was directly dependent on the level of ET in the general circulation and on an activity of AEI. Examination stress in the third group of volunteers is accompanied by activation of plasma hemostasis (increased initial thrombosis rate and reduced the time it starts, lag-period) in 26% of female students and 15% of male students. We suggest that it is possible to use the PES as a clinical model

  6. Photography in Dermatologic Surgery: Selection of an Appropriate Camera Type for a Particular Clinical Application. (United States)

    Chen, Brian R; Poon, Emily; Alam, Murad


    Photographs are an essential tool for the documentation and sharing of findings in dermatologic surgery, and various camera types are available. To evaluate the currently available camera types in view of the special functional needs of procedural dermatologists. Mobile phone, point and shoot, digital single-lens reflex (DSLR), digital medium format, and 3-dimensional cameras were compared in terms of their usefulness for dermatologic surgeons. For each camera type, the image quality, as well as the other practical benefits and limitations, were evaluated with reference to a set of ideal camera characteristics. Based on these assessments, recommendations were made regarding the specific clinical circumstances in which each camera type would likely be most useful. Mobile photography may be adequate when ease of use, availability, and accessibility are prioritized. Point and shoot cameras and DSLR cameras provide sufficient resolution for a range of clinical circumstances, while providing the added benefit of portability. Digital medium format cameras offer the highest image quality, with accurate color rendition and greater color depth. Three-dimensional imaging may be optimal for the definition of skin contour. The selection of an optimal camera depends on the context in which it will be used.

  7. Economic impact of clinical variability in preoperative testing for major outpatient surgery. (United States)

    Gil-Borrelli, Christian Carlo; Agustí, Salomé; Pla, Rosa; Díaz-Redondo, Alicia; Zaballos, Matilde


    With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

  8. Surgical checklist for cataract surgery: progress with the initiative by the Royal College of Ophthalmologists to improve patient safety (United States)

    Kelly, S P; Steeples, L R; Smith, R; Azuara-Blanco, A


    Purpose The World Health Organisation (WHO) identified patient safety in surgery as an important public health matter and advised the adoption of a universal peri-operative surgical checklist. An adapted version of the WHO checklist has been mandatory in the National Health Service since 2010. Wrong intraocular lens (IOL) implantation is a particular safety concern in ophthalmology. The Royal College of Ophthalmologists launched a bespoke checklist for cataract surgery in 2010 to reduce the likelihood of preventable errors. We sought to ascertain the use of checklists in cataract surgery in 2012. Patients and methods A survey of members of the Royal College of Ophthalmologists seeking views on the use of checklists in cataract surgery. Four hundred and sixty-nine completed responses were received (18% response rate). Results Respondents worked in England (75%), Scotland (11%), Wales (5%), Northern Ireland (2%), the Republic of Ireland (1%), and overseas (6%). Ninety-four per cent of respondents support the use of a checklist for cataract surgery and 85% say that they always use a checklist before cataract surgery. Sixty-seven per cent of cataract surgeons stated they undertake a pre-operative team brief. Thirty-six per cent use a cataract surgery checklist developed locally, 18% use the college's bespoke cataract surgery checklist, 39% use a generic surgical checklist, and 4% reported that they do not use a checklist. Conclusion Ninety-three per cent of cataract surgeons responding to the questionnaire report using a surgical checklist and 67% use a team brief. However, only 54% use a checklist, which addresses the selection of the correct intraocular implant. We recommend wider adoption of checklists, which address risks relevant to cataract surgery, in particular the possibility of selection of an incorrect IOL. PMID:23703633

    To study the clinical characteristics of children with an initial onset of IgA nephropathy with nephrotic syndrome and compare them with children with primary nephrotic syndrome, in order to provide a theoretical basis for the differential diagnosis of the two diseases. Fifty children diagnosed with an initial onset of IgA nephropathy with nephrotic syndrome were included in this study. Seventy-two children diagnosed with an initial onset of primary nephrotic syndrome served as the control group. The clinical and laboratory examination characteristics were compared between the two groups. The IgA nephropathy group had significantly higher incidence rates of gross haematuria, microscopic haematuria, hypertension, acute kidney injury, low serum high-density lipoprotein cholesterol, anemia, low serum complement C4, steroid resistance, and nephritis-type nephrotic syndrome and a significantly lower incidence of elevated serum IgE compared with the control group (Psyndrome and primary nephrotic syndrome. Children with IgA nephropathy presenting nephrotic syndrome manifest mainly as nephritis type and steroid-resistant type in the clinical classification. Cinical manifestations accompanied by serum levels of high-density lipoprotein cholesterol and IgE are helpful for differential diagnosis of IgA nephropathy presenting nephrotic syndrome and primary nephrotic syndrome.

    Male genital dysfunction was recognized as a complication following anterior approach lumbar surgery. Disruption of efferent sympathetic pathways such as the abdominal aortic plexus (AAP) and superior hypogastric plexus (SHP) which lied pre-abdominal aorta and iliac artery had been thought as the main reason. Though there were some clinical reports of retrograde ejaculation, the applied anatomic study of the autonomic nerve anterior to the lumbar was little. The purpose was to find out a lumbar surgery approach which was ejaculation preservation through the detailed study of the anatomy and histology observation of the autonomic nerve anterior to the lumbar vertebrae. The lumbar region of ten male cadavers was dissected and analyzed. We investigated the relationship between the peritoneum and abdominal aorta, iliac artery and sacral promontory fascia, as well as the trend and distribution of the autonomic nerve and SHP anterior to the L5-S1. We also observed the distribution of autonomic nerve at retroperitoneum through hematoxylin and eosin (HE)-stained tissues pre-aorta, para-aorta, and pre-vertebrae sacrales. Superior hypogastric plexus, which deviated to left, located in a triangle formed by the common iliac arteries and its bilateral branches, its truck sited anterior to the lumbarsacral space in seven cases (70%), and anterior to sacrum in three cases (30%); at the aortic bifurcation, SHP strided over left iliac artery from left-hand side, then located in front of sacrum in four cases (40%), and sifted to the left at the lumbar sacral promontory in six cases (60%); from both anatomic and histological view, the autonomic nerve plexus lying in an fascia layer of retroperitoneum. At the anterior approach lumbar surgery of trans-peritoneum, we should choose the right-hand side incision; the SHP should be pushed aside carefully from right to left along intervertebral disc. The accurate surgical plane was at the deeper layer of autonomical nerve fascia; we also

  11. Application of platelet-rich plasma in plastic surgery: clinical and in vitro evaluation. (United States)

    Cervelli, Valerio; Gentile, Pietro; Scioli, Maria Giovanna; Grimaldi, Monica; Casciani, Carlo Umberto; Spagnoli, Luigi Giusto; Orlandi, Augusto


    The clinical use of platelet-rich plasma (PRP) for a wide variety of application has been reportedly employed most prevalently in problematic wounds, maxillofacial and hemi-facial atrophy, Romberg Syndrome, and diabetic foot ulcers. To our knowledge, PRP has never been described in the enhancement of fat grafting during tissue-engineering application in vivo. The authors describe the preparation of PRP and its use in a series of 43 patients who underwent plastic, reconstructive, and maxillofacial surgery for chronic lower extremity ulcers (n = 18) and multiple facial applications (n = 25). PRP mixed with fat grafting was used in 76% patients affected by multiple facial diseases and in 88.9% patients affected by lower extremity ulcers. PRP injection alone was used in the remaining patients. The authors observed that after a 7.1-week and 9.7-week (average) course of twice-daily wound treatment with PRP suspended on a collagen base, 61.1% and 88.9% of chronic lower extremity ulcers underwent to 100% reepithelization compared with 40% and 60% of controls (n = 10) treated with hyaluronic acid and collagen medication. In patients treated with reconstructing three-dimensional projection of face by fat grafting and PRP, we observed a 70% maintenance of contour restoring and three-dimensional volume after 1 year compared to only 31% of controls (n = 10) treated with fat grafting alone. In vitro, PRP induced a significant increase in the number of adipose-tissue-derived stem cells compared to control cultures. These results documented that PRP accelerates chronic skin ulcer reepithelization and improves maintenance and function of fat graft in patients who underwent plastic reconstructive surgery, possibly by stimulating adipose-tissue-derived stem cell proliferation.

  12. Reduction of postoperative pulmonary complications after lung surgery using a fast track clinical pathway. (United States)

    Muehling, Bernd M; Halter, Gisela L; Schelzig, Hubert; Meierhenrich, Rainer; Steffen, Peter; Sunder-Plassmann, Ludger; Orend, Karl-Heinz


    Fast track programs, multimodal therapy strategies, have been introduced in many surgical fields to minimize postoperative morbidity and mortality. In terms of lung resections no randomized controlled trials exist to evaluate such patient care programs. In a prospective, randomized controlled pilot study a conservative and fast track treatment regimen in patients undergoing lung resections was compared. Main differences between the two groups consisted in preoperative fasting (6h vs 2h) and analgesia (patient controlled analgesia vs patient controlled epidural analgesia). Study endpoints were pulmonary complications (pneumonia, atelectasis, prolonged air leak), overall morbidity and mortality. Analysis was performed in an intention to treat. Both study groups were similar in terms of age, sex, preoperative forced expiratory volume in one second (FEV(1)), American Society of Anesthesiologists score and operations performed. The rate of postoperative pulmonary complications was 35% in the conservative and 6.6% in the fast track group (p=0.009). A subgroup of patients with reduced preoperative FEV(1) (<75% of predicted value) experienced less pulmonary complications in the fast track group (55% vs 7%, p=0.023). Overall morbidity was not significantly different (46% vs 26%, p=0.172), mortality was comparable in both groups (4% vs 3%). We evaluated an optimized patient care program for patients undergoing lung resections in a prospective randomized pilot study. Using this fast track clinical pathway the rate of pulmonary complications could be significantly decreased as compared to a conservative treatment regimen; our results support the implementation of an optimized perioperative treatment in lung surgery in order to reduce pulmonary complications after major lung surgery.

    Yajima, M; Baba, K; Yanagisawa, N; Nishida, T; Yamakawa, K; Takemura, H; Nishida, S; Iwamoto, T


    From December 1996 to June 1998, we performed transurethral surgery of the prostate using a thick loop, VaporTome developed by Circon ACMI on 23 patients with symptomatic benign prostatic hyperplasia (BPH). The mean international prostate symptom score decreased significantly, from 22.6 at baseline to 9.0, 6.5, 4.9 and 5.3 at 1, 3, 6 and 12 months after operation, respectively. The mean quality of life index also decreased significantly, from 5.5 to 1.8, 1.8, 1.4 and 1.2, respectively. The mean peak flow rate increased significantly, from 6.2 preoperatively to 15.8, 17.1, 16.6 and 17.4 ml/sec at 1, 3, 6 and 12 months after operation, respectively. The mean prostate volume decreased significantly, from 66.9 to 24.8, 17.3, 19.0 and 18.2 ml. The mean residual urine decreased significantly, from 167.9 to 11.4, 9.4, 12.8 and 20.4 ml. As for overall efficacy, the rate of excellent and good cases at 1, 3, 6 and 12 months was 80.9, 89.4, 94.7 and 85.8%, respectively. No serious complications were observed. Our clinical results suggest that transurethral surgery for BPH using VaporTome has several potential advantages including high efficacy, minimal morbidity compared with standard transurethral resection of the prostate and lower cost compared with other minimally invasive procedures.

    Rosa, Simone Corrêa; Macedo, Jefferson Lessa Soares DE; Casulari, Luiz Augusto; Canedo, Lucas Ribeiro; Marques, João Vitor Almeida


    to evaluate the profile of patients submitted to post-bariatric plastic surgery at the North Wing Regional Hospital, Brasília, DF. we conducted a prospective, descriptive and analytical study of patients submitted to Roux-en-Y gastroplasty, and subsequently to plastic surgery, from January 2011 to December 2016. We assessed body mass index before gastroplasty and after surgery plastic surgery, postoperative complications and comorbidities. we studied 139 patients (130 women and nine men), with a mean age of 41 years, who underwent 233 operations. The mean BMI at the time of plastic surgery was 27.44kg/m2. The mean weight loss was 47.02kg and the mean maximum BMI was 45.17kg/m2. The mean time between bariatric surgery and plastic surgery was 42 months. The most important co-morbidities before plastic surgery were arterial hypertension (11.5%), arthropathy (5.4%), diabetes mellitus (5%) and metabolic syndrome (4.3%) (pprofile of post-bariatric patients who underwent plastic surgery was similar to that reported in the literature, except for the low rate of associated surgeries and postoperative complications. Plastic surgery in post-bariatric patients has led to an improvement in the quality of life in most of these patients.

  15. Delayed Adjacent Level Spondylodiscitis after Initial Surgery with Instrumented Spinal Fusion: A Report of Three Cases and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Narihito Nagoshi


    Full Text Available To date, 2 cases of adjacent level spondylodiscitis occurring a few months after initial spinal fusion were reported. However, the development of delayed adjacent level spondylodiscitis is very rare. The authors report 3 cases of spondylodiscitis that occurred at the proximal adjacent level of the fused spine more than 1 year after the initial surgery. Antibiotic treatment was initially chosen in all three cases. In two of the cases, progressive neurological deficit occurred at the level of the infection due to compression of neural elements and spinal instability. For these patients, additional spinal fusion was performed. In each of the three cases, the selected treatment resulted in successful bony fusion at the level of the spondylodiscitis. According to the National Nosocomial Infections Surveillance System, deep wound infection is defined as occurring within 1 year after surgery with instrumentation. The spondylodiscitis in the present cases occurred more than 1 year after the initial surgery, suggesting that these cases may be considered as adjacent segment disease rather than surgical site infection.

    Macleod, Liam C; Odisho, Anobel Y; Tykodi, Scott S; Holt, Sarah K; Harper, Jonathan D; Gore, John L


    To use econometric methods to assess comparative overall survival of patients with metastatic renal cell carcinoma (mRCC) managed with initial cytoreductive nephrectomy (CN) vs initial systemic therapy. Randomized data demonstrate improved survival for CN preceding cytokine-based therapy in mRCC. This benefit may be attenuated in the contemporary mRCC era given more effective systemic therapies. Patients over age 65 with mRCC from the Surveillance, Epidemiology, and End Results registries linked with Medicare claims from 2006 to 2011 were categorized by initial treatment. We applied sequential survival analysis methods to assess the association between initial CN and overall survival (OS) including Cox proportional hazards models, propensity scoring, and instrumental variable analysis to account for measured and unmeasured selection bias. Of 537 patients analyzed, 190 had initial CN followed by targeted therapy and 347 had initial targeted therapy. Median OS in the initial CN group was 17.4 months (interquartile range 9.8-32.0), compared with 9.2 months (interquartile range 4.3-18.0) for initial targeted therapy. Cox proportional hazards analysis revealed initial CN was associated with improved OS (hazard ratio 0.50, 95% confidence interval [CI] 0.38-0.65). Propensity matching demonstrated a survival advantage for initial CN of 5.8 months (95% CI 1.9-9.7). Accounting for unmeasured confounding with instrumental variable analysis demonstrated a trend toward improved survival with initial CN (hazard ratio 0.29 [95% CI 0.08-1.00]). Initial CN is associated with improved survival compared with initial systemic therapy in a contemporary population-based mRCC cohort. Copyright © 2017 Elsevier Inc. All rights reserved.

  18. Immediate occlusal loading in edentulous jaws, CT-guided surgery and fixed provisional prosthesis: a maxillary arch clinical report. (United States)

    Drago, Carl; del Castillo, Robert; Peterson, Thomas


    Immediate occlusal loading (IOL) in edentulous jaws has been reported in numerous publications with implant cumulative survival rates consistent with conventional, unloaded healing protocols. Computed Tomography (CT)-guided surgery has more recently been developed and accepted as an additional treatment modality for maxillary and mandibular implant placement, with or without IOL. Reports as to the accuracy of planned versus actual implant placement in CT-guided surgeries have indicated that CT-guided surgery is not 100% accurate; standard deviations have been reported with values between 1 and 2 mm in terms of actual versus planned placement. The purpose of this article is to review the clinical parameters associated with IOL, and CT-guided surgery in edentulous jaws; and to present a clinical case illustrating the clinical and laboratory phases of treatment. The illustrated treatment was accomplished with an IOL protocol and includes fabrication and placement of a laboratory-processed provisional maxillary prosthesis. This particular protocol had slightly increased costs relative to conventional implant placement; however, the clinicians and patient benefited from improved accuracy of the provisional prostheses and decreased chairtime for the clinical procedures. The benefits and limitations of this treatment protocol are also discussed. © 2010 by The American College of Prosthodontists.

  19. Minimal Clinically Important Differences for American Orthopaedic Foot & Ankle Society Score in Hallux Valgus Surgery. (United States)

    Chan, Hiok Yang; Chen, Jerry Yongqiang; Zainul-Abidin, Suraya; Ying, Hao; Koo, Kevin; Rikhraj, Inderjeet Singh


    The American Orthopaedic Foot & Ankle Society (AOFAS) score is one of the most common and adapted outcome scales in hallux valgus surgery. However, AOFAS is predominantly physician based and not patient based. Although it may be straightforward to derive statistical significance, it may not equate to the true subjective benefit of the patient's experience. There is a paucity of literature defining MCID for AOFAS in hallux valgus surgery although it could have a great impact on the accuracy of analyzing surgical outcomes. Hence, the primary aim of this study was to define the Minimal Clinically Important Difference (MCID) for the AOFAS score in these patients, and the secondary aim was to correlate patients' demographics to the MCID. We conducted a retrospective cross-sectional study. A total of 446 patients were reviewed preoperatively and followed up for 2 years. An anchor question was asked 2 years postoperation: "How would you rate the overall results of your treatment for your foot and ankle condition?" (excellent, very good, good, fair, poor, terrible). The MCID was derived using 4 methods, 3 from an anchor-based approach and 1 from a distribution-based approach. Anchor-based approaches were (1) mean difference in 2-year AOFAS scores of patients who answered "good" versus "fair" based on the anchor question; (2) mean change of AOFAS score preoperatively and at 2-year follow-up in patients who answered good; (3) receiver operating characteristic (ROC) curves method, where the area under the curve (AUC) represented the likelihood that the scoring system would accurately discriminate these 2 groups of patients. The distribution-based approach used to calculate MCID was the effect size method. There were 405 (90.8%) females and 41 (9.2%) males. Mean age was 51.2 (standard deviation [SD] = 13) years, mean preoperative BMI was 24.2 (SD = 4.1). Mean preoperative AOFAS score was 55.6 (SD = 16.8), with significant improvement to 85.7 (SD = 14.4) in 2 years ( P value

    Park, Moon Soo; Kelly, Michael P; Lee, Dong-Ho; Min, Woo-Kie; Rahman, Ra'Kerry K; Riew, K Daniel


    Postoperative malalignment of the cervical spine may alter cervical spine mechanics and put patients at risk for clinical adjacent segment pathology requiring surgery. To investigate whether a relationship exists between cervical spine sagittal alignment and clinical adjacent segment pathology requiring surgery (CASP-S) following anterior cervical fusion (ACF). Retrospective matched study. A total of 122 patients undergoing ACF between 1996 and 2008 were identified, with a minimum of 2 years of follow-up. Radiographs were reviewed to measure the sagittal alignment using C2 and C7 sagittal plumb lines, distance from the fusion mass plumb line to the C2 and C7 plumb lines, the alignment of the fusion mass, caudally adjacent disc angle, the sagittal slope angle of the superior end plate of the vertebra caudally adjacent to the fusion mass, T1 sagittal angle, overall cervical sagittal alignment, and curve patterns by Katsuura classification.

    Since 2001, the National Drug Abuse Treatment Clinical Trials Network (CTN) has worked to put the results of its trials into the hands of community treatment programs, in large part through its participation in the National Institute on Drug Abuse - Substance Abuse and Mental Health Services Administration Blending Initiative and its close involvement with the Center for Substance Abuse Treatment’s Addiction Technology Transfer Centers. This article describes 1) the CTN’s integral role in the Blending Initiative, 2) key partnerships and dissemination pathways through which the results of CTN trials are developed into blending products and then transferred to community treatment programs, and 3) three blending initiatives involving buprenorphine, motivational incentives, and motivational interviewing. The Blending Initiative has resulted in high utilization of its products, preparation of over 200 regional trainers, widespread training of service providers in most U.S. States, Puerto Rico, and the U.S. Virgin Islands, and movement toward the development of web-based implementation supports and technical assistance. Implications for future directions of the Blending Initiative and opportunities for research are discussed. PMID:20307793

  3. Designing a Clinical Data Warehouse Architecture to Support Quality Improvement Initiatives. (United States)

    Chelico, John D; Wilcox, Adam B; Vawdrey, David K; Kuperman, Gilad J


    Clinical data warehouses, initially directed towards clinical research or financial analyses, are evolving to support quality improvement efforts, and must now address the quality improvement life cycle. In addition, data that are needed for quality improvement often do not reside in a single database, requiring easier methods to query data across multiple disparate sources. We created a virtual data warehouse at NewYork Presbyterian Hospital that allowed us to bring together data from several source systems throughout the organization. We also created a framework to match the maturity of a data request in the quality improvement life cycle to proper tools needed for each request. As projects progress in the Define, Measure, Analyze, Improve, Control stages of quality improvement, there is a proper matching of resources the data needs at each step. We describe the analysis and design creating a robust model for applying clinical data warehousing to quality improvement.

    Determine the cost and cost-effectiveness of single-visit (same-day) antiretroviral treatment (ART) initiation compared to standard of care initiation. Cost-effectiveness analysis of individually randomized (1 : 1) pragmatic trial of single-visit initiation, which increased viral suppression at 10 months by 26% [relative risk (95% confidence interval) 1.26 (1.05-1.50)]. Primary health clinic in Johannesburg, South Africa. HIV positive, adult, nonpregnant patients not yet on ART or known to be eligible who presented at the clinic 8 May 2013 to 29 August 2014. Same-day ART initiation using point-of-care laboratory instruments and accelerated clinic procedures to allow treatment-eligible patients to receive antiretroviral medications at the same visit as testing HIV positive or having an eligible CD4 cell count. Comparison was to standard of care ART initiation, which typically required three to five additional clinic visits. Average cost per patient enrolled and per patient achieving the primary outcome of initiated 90 days or less and suppressed 10 months or less, and production cost per patient achieving primary outcome (all costs per primary outcome patients). The average cost per patient enrolled, per patient achieving the primary outcome, and production cost were $319, $487, and $738 in the standard arm and $451, $505, and $707 in the rapid arm. Same-day treatment initiation was more effective than standard initiation, more expensive per patient enrolled, and less expensive to produce a patient achieving the primary outcome. Omitting point-of-care laboratory tests at initiation and focusing on high-volume clinics have the potential to reduce costs substantially and should be evaluated in routine settings.

    To establish a pilot clinical quality registry (CQR) to monitor the quality of care and device performance for breast device surgery in Australia. All patients having breast device surgery from contributing hospitals in Australia. A literature review was performed which identified quality indicators for breast device surgery. A pilot CQR was established in 2011 to capture prospective data on breast device surgery. An interim Steering Committee and Management Committee were established to provide clinical governance, and guide quality indicator selection. The registry's minimum dataset was formulated in consultation with stakeholder groups; potential quality indicators were assessed in terms of (1) importance and relevance, (2) usability, (3) feasibility to collect and (4) scientific validity. Data collection was by a two-sided paper-based form with manual data entry. Seven sites were recruited, including one public hospital, four private hospitals and two day surgeries. Patients were recruited and opt-out consent used. The pilot breast device registry provides high-quality population-based data. It provides a model for developing a national CQR for breast devices; its minimum dataset and quality indicators reflect the opinions of the broad range of stakeholders. It is easily scalable, and has formed the basis for other international surgical groups establishing similar registries. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Background/Aim. Surgical and chronic wounds in vascular patients might contribute to limb loss and death. Vacuum-assisted closure (VAC - Kinetic Concepts, Inc. (KCI, has been increasingly used in Western Europe and the USA clinical practice for 15 years. Advantages of this method are faster wound healing, wound approximation, lower wound related treatment costs and improved quality of life during treatment. Evidence related to the usage of VAC therapy in vascular patients and cost effectiveness of VAC therapy in a developing country are lacking. The aim of this study was to explore results of VAC therapy in vascular surgery comparing to conventional methods and to test cost effects in a developing country like Serbia. Methods. All patients with wound infection or dehiscence operated at the tertiary vascular university clinic in the period from January 2011 - January 2012, were treated with VAC therapy. The primary endpoint was wound closure, while secondary endpoints were hospital stay, the number of weekly dressings, costs of wound care, working time of medical personnel. The patients were divided into groups according to the wound type and location: wound with exposed synthetic vascular implant (25%, laparotomy (13%, foot amputation (29%, major limb amputation (21%, fasciotomy (13%. The results of primary and secondary endpoint were compared with the results of conventional treatment during the previous year. Results. There was one death (1/42, 2.38% and one limb loss (1/12, 2.38% in the VAC group, and 8 deaths (8/38, 21.05% and 5 (5/38, 13.15% limb losses in the patients treated with conventional therapy. In the VAC group there was one groin bleeding (1/12, 2.38%, one groin reinfection (1/12, 2.38% and one resistance to therapy with a consequent limb loss. Costs of hospital stay (p < 0.001 and nursing time (p < 0.001 were reduced with VAC therapy in the group with exposed graft. Conclusion. VAC therapy is the effective method for care of

IOP measurement during the postoperative periods was classified based on the postoperative day: week 1 (1–7 days, month 1 (8–41 days, month 2 (42–70 days, month 3 (71–97 days, month 4 (98–126 days, and final (after 127 days. The mean postoperative follow-up was 286.5 days for orbits with at least 6 months of follow-up. Univariate and multivariate linear regression analyses were performed to assess the correlation between the IOP reduction percentage and clinical factors.Results: The mean IOP increased from 16.9 to 18.6 mmHg (10.1% at postoperative week 1 and decreased to 14.4 mmHg (14.5% after 2 months. Minimal little changes were observed postoperatively in the IOP after 2 months. Preoperative IOP had a significant positive effect on the reduction percentage both at postoperative week 1 (β=2.51, P=0.001 and after 2 months (β=1.07, P=0.029, and the spherical equivalent showed a positive correlation with the reduction level at postoperative week 1 (β=1.71, P=0.021.Conclusion: Surgical decompression caused a significant reduction in the IOP in thyroid-associated orbitopathy, and the amount of reduction was closely related to preoperative IOP; however, it may also cause a transient elevation in the IOP during the early postoperative phase in highly myopic eyes.

    The aim of this study was to compare the efficacy of preoperative and postoperative dexketoprofen trometamol for pain control after third molar surgery. Sixty subjects indicated for impacted mandibular third molar surgery were randomly assigned to two groups: preoperative (group 1, n = 30) and postoperative (group 2, n = 30) administration. Group 1 received 25 mg of dexketoprofen trometamol 30 min before surgery and 1 placebo capsule (same color and size with active drug) immediately after surgery. Group 2 received the placebo capsule 30 min before surgery and 25 mg of dexketoprofen trometamol immediately after surgery. Pain intensity was assessed using a numeric rating scale (NRS) during the first 8 h. The time of the need for a second dose of dexketoprofen trometamol, after the first administration, was recorded. The data were analyzed using mixed-model repeated-measures (MMRM), Wilcoxon rank-sum, and Kaplan-Meier analysis. After the 8 h period, no statistically significant difference was observed in the intensity of pain (MMRM, p = 0.41); and no significant difference in the time for a second dose (p = 0.956). In conclusion, preoperative administration of dexketoprofen trometamol is a reasonable clinical approach that is as effective as conventional postoperative pharmacological treatment, with the advantage of allowing early analgesia before pain develops.

  9. Sick leave and disability pension before and after initiation of antirheumatic therapies in clinical practice. (United States)

    Neovius, M; Simard, J F; Klareskog, L; Askling, J


    To investigate sick leave and disability pension in rheumatoid arthritis (RA) in relation to the initiation of biological and non-biological antirheumatic therapies in clinical practice. Patients aged 19-60 years initiating non-biological mono (n=2796) or combination disease-modifying antirheumatic drug (DMARD) therapy (n=973), or biological agents (n=4787) were identified in the Swedish Rheumatology Quality Register between 1999 and 2007. Sick leave and disability pension data (1995-2010) were retrieved from national registers. During the year before the start of mono DMARD, combination DMARD and biological treatment, 10%, 12% and 43% of patients received disability pension benefits, respectively. The corresponding combined annual sick leave and disability pension days were 78 (54+25), 132 (105+27) and 190 (79+111). Irrespective of treatment type, initiators were characterised by a history of increasing sick leave and disability pension. Treatment start was associated with a break in this trajectory: sick leave decreased while disability pension increased, resulting in a net stabilisation of total days. Higher levels of days on sick leave and disability pension at treatment start were observed in patients initiating biologics in 1999 (236 days/year) compared with 2007 (150 days/year; pleave and disability pension increased rapidly before the initiation of antirheumatic therapy, which was associated with a halt but not a reversal of this development. Work ability is a metric of importance for clinical practice, signalling large remaining needs in the RA population, and the need for intervention earlier in the disease process.

    Retrospective cohort comparative study. To determine the prevalence of major complications, identify risk factors, and assess long-term clinical benefit after revision adult spinal deformity surgery. No study has analyzed risk factors for major complications in long revision fusion surgery and whether or not occurrence of a major complication affects ultimate clinical outcome. Analysis of consecutive adult patients who underwent multilevel revision surgery for spinal deformity with a minimum 2-year follow-up was performed. All complications were classified as either major or minor. Outcome analysis was conducted with the Scoliosis Research Society and Oswestry Disability Index scores. A total of 166 patients (mean age = 53.8 years) were identified with a mean follow-up of 3.5 years (range: 2-7). Primary diagnoses included idiopathic/de novo scoliosis (107), degenerative (35), trauma (7), neuromuscular scoliosis (6), congenital deformity (5), ankylosing spondylitis (2), tumor (2), Scheuermann kyphosis (1), and rheumatoid arthritis (1). Most common secondary diagnoses that necessitated revision surgery were adjacent segment disease, fixed sagittal imbalance, and pseudarthrosis. Overall, 34.3% of patients developed major complications (19.3% perioperative; 18.7% follow-up). Associated risk factors for perioperative complications were patient- (age > 60 years, medical comorbidities, obesity) and surgery-related (pedicle subtraction osteotomy). Performance of a 3-column osteotomy and postoperative radiographic changes that suggested progressive loss of sagittal correction were recognized as risk factors for follow-up complications. Equivalent outcome scores were reported by patients preoperatively, but those experiencing follow-up complications reported lower scores at the final follow-up. Overall, 34.4% of patients experienced major complications after long revision fusion surgery. Different risk factors were identified for perioperative versus follow-up complications

  11. Ultrasound-guided breast-sparing surgery to improve cosmetic outcomes and quality of life. A prospective multicentre randomised controlled clinical trial comparing ultrasound-guided surgery to traditional palpation-guided surgery (COBALT trial) (United States)


    Background Breast-conserving surgery for breast cancer was developed as a method to preserve healthy breast tissue, thereby improving cosmetic outcomes. Thus far, the primary aim of breast-conserving surgery has been the achievement of tumour-free resection margins and prevention of local recurrence, whereas the cosmetic outcome has been considered less important. Large studies have reported poor cosmetic outcomes in 20-40% of patients after breast-conserving surgery, with the volume of the resected breast tissue being the major determinant. There is clear evidence for the efficacy of ultrasonography in the resection of nonpalpable tumours. Surgical resection of palpable breast cancer is performed with guidance by intra-operative palpation. These palpation-guided excisions often result in an unnecessarily wide resection of adjacent healthy breast tissue, while the rate of tumour-involved resection margins is still high. It is hypothesised that the use of intra-operative ultrasonography in the excision of palpable breast cancer will improve the ability to spare healthy breast tissue while maintaining or even improving the oncological margin status. The aim of this study is to compare ultrasound-guided surgery for palpable tumours with the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumour-free margins, cosmetic outcomes and quality of life. Methods/design In this prospective multicentre randomised controlled clinical trial, 120 women who have been diagnosed with palpable early-stage (T1-2N0-1) primary invasive breast cancer and deemed suitable for breast-conserving surgery will be randomised between ultrasound-guided surgery and palpation-guided surgery. With this sample size, an expected 20% reduction of resected breast tissue and an 18% difference in tumour-free margins can be detected with a power of 80%. Secondary endpoints include cosmetic outcomes and quality of life. The rationale, study

    Yumioka, Tetsuya; Iwamoto, Hideto; Masago, Toshihiko; Morizane, Shuichi; Yao, Akihisa; Honda, Masashi; Muraoka, Kuniyasu; Sejima, Takehiro; Takenaka, Atsushi


    To evaluate the influence of prior abdominal surgery on surgical outcomes of robot-assisted radical prostatectomy in an early single center experience in Japan. We reviewed medical records of patients with localized prostate cancer who underwent robot-assisted radical prostatectomy from October 2010 to September 2013 at Tottori University Faculty of Medicine, Yonago, Tottori, Japan. Patients with prior abdominal surgery were compared with those with no prior surgery with respect to total operative time, port-insertion time, console time, positive surgical margin and perioperative complication rate. Furthermore, the number of patients requiring minimal adhesion lysis was compared between the two groups. Of 150 patients who underwent robot-assisted radical prostatectomy, 94 (63%) had no prior abdominal surgery, whereas 56 patients (37%) did. The mean total operative time was 329 and 333 min (P = 0.340), mean port insertion time was 40 and 34.5 min (P = 0.003), mean console time was 255 and 238 min (P = 0.145), a positive surgical margin was observed in 17.9% and 17.0% patients (P = 0.896), and the incidence of perioperative complications was 25% and 23.4% (P = 0.825), respectively, in those with and without prior abdominal surgery. In the prior abdominal surgery group, 48 patients (80.4%) required adhesion lysis at the time of trocar placement or while operating the robotic console. Robot-assisted radical prostatectomy appears to be a safe approach for patients with prior abdominal surgery without increasing total operative time, robotic console time, positive surgical margin or the incidence of perioperative complications. © 2014 The Japanese Urological Association.

    Shah Shagun B


    Full Text Available Endoscopic Endonasal Trans-sphenoid Surgery (EETS aided by avant-garde neuro-navigation techniques, ultrasonic aspirators and bone curettes has come of age. Endoscopic surgery supersedes conventional microscopic approach due to better visualization, avoidance of craniotomy, brain retraction and undue neurovascular manipulation with less morbidity, blood loss and improved safety. Anaesthetic techniques must be tailored to cater for such advances in surgery.

  16. Clinical guidelines for management of diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion after pituitary surgery. (United States)

    Lamas, Cristina; del Pozo, Carlos; Villabona, Carles


    Changes in water metabolism and regulation of vasopressin (AVP) or antidiuretic hormone (ADH) are common complications of pituitary surgery. The scarcity of studies comparing different treatment and monitoring strategies for these disorders and the lack of prior clinical guidelines makes it difficult to provide recommendations following a methodology based on grades of evidence. This study reviews the pathophysiology of diabetes insipidus and inappropriate ADH secretion after pituitary surgery, and is intended to serve as a guide for their diagnosis, differential diagnosis, treatment, and monitoring.

  20. Effectiveness of surgery and individualized high-dose hyperfractionated accelerated radiotherapy on survival in clinical stage I non-small cell lung cancer. A propensity score matched analysis

    International Nuclear Information System (INIS)

    Jimenez, Marcelo F.; Baardwijk, Angela van; Aerts, Hugo J.W.L.; De Ruysscher, Dirk; Novoa, Nuria M.; Varela, Gonzalo; Lambin, Philippe


    Background and purpose: Surgery is considered the treatment of choice for early-stage non-small cell lung cancer (NSCLC). Patients with poor pulmonary function or other comorbidities are treated with radiotherapy. The objective of this investigation is to compare the 3-year survival of two early-stage NSCLC populations treated in two different hospitals, either by surgical resection (lobectomy) or by individualized high-dose accelerated radiotherapy, after matching patients by propensity scoring analysis. Methods: A retrospective comparative study has been performed on two series of consecutive patients with cytohistological diagnosis of NSCLC, clinically staged IA by means of PET-scan (radiotherapy group) and pathologically staged IA (surgery group). Results: A total of 157 cases were initially selected for the analysis (110 operated and 47 treated by radiotherapy). Patients in the radiotherapy group were older, with higher comorbidity and lower FEV1% with 3-years probability of survival for operated patients higher than that found for patients treated by radiotherapy. After matching by propensity scoring (using age and FEV1%), differences disappear and 3-years probability of survival had no statistical differences. Conclusions: Although this is a non-randomized retrospective analysis, we have not found 3-years survival differences after matching cases between surgery and radiotherapy. Nevertheless, data presented here support the continuous investigation for non-surgical alternatives in this disease.

  1. Clinical application of micro-implant anchorage in initial orthodontic retraction. (United States)

    Wahabuddin, Shaji; Mascarenhas, Rohan; Iqbal, Mahamad; Husain, Akhter


    Micro-implant is a device that is temporarily fixed to bone for the purpose of enhancing orthodontic anchorage either by supporting the teeth of the reactive unit or by obviating the need for the reactive unit altogether, and which is subsequently removed after use. The purpose of this study was to evaluate the clinical efficiency of micro-implants in reinforcing anchorage during the initial retraction of anterior teeth, check the rate of initial retraction for 8 weeks, and assess the stability of micro-implants during this period. Eighteen micro-implants were placed (10 in the maxilla and 8 in the mandible) and immediately loaded with 200-250 g of force using 9-mm closed coil Nitinol springs. The amount of space closure was measured every 2 weeks until the eighth week. Cephalometric measurements were made at the end of the study to evaluate anchor loss, if any. Micro-implant stability was also assessed. The rate of initial retraction in the maxilla at the end of 8 weeks was 1.65 mm/quadrant and 1.51 mm/quadrant in the mandible. The amount of retraction on the left side of the arches was 1.66 mm/quadrant and 1.49 mm/quadrant on the right side. The average initial retraction for both arches per month was 0.78 mm. An anchor loss of 0.1 mm (0.06%) was observed in the maxilla while no mandibular anchor loss was recorded. The rate of initial retraction observed in the maxilla was more than that achieved in the mandible. Initial retraction was also more on the left side of the arches. There was no anchor loss in the mandible. The micro-implant-reinforced anchorage was helpful in minimizing anchor loss and accepted heavy traction forces but did not bring about a faster rate of retraction.

  2. Has increased clinical experience with methotrexate reduced the direct costs of medical management of ectopic pregnancy compared to surgery? (United States)

    Westaby, Daniel T; Wu, Olivia; Duncan, W Colin; Critchley, Hilary O D; Tong, Stephen; Horne, Andrew W


    There is a debate about the cost-efficiency of methotrexate for the management of ectopic pregnancy (EP), especially for patients presenting with serum human chorionic gonadotrophin levels of >1500 IU/L. We hypothesised that further experience with methotrexate, and increased use of guideline-based protocols, has reduced the direct costs of management with methotrexate. We conducted a retrospective cost analysis on women treated for EP in a large UK teaching hospital to (1) investigate whether the cost of medical management is less expensive than surgical management for those patients eligible for both treatments and (2) to compare the cost of medical management for women with hCG concentrations 1500-3000 IU/L against those with similar hCG concentrations that elected for surgery. Three distinct treatment groups were identified: (1) those who had initial medical management with methotrexate, (2) those who were eligible for initial medical management but chose surgery ('elected' surgery) and (3) those who initially 'required' surgery and did not meet the eligibility criteria for methotrexate. We calculated the costs from the point of view of the National Health Service (NHS) in the UK. We summarised the cost per study group using the mean, standard deviation, median and range and, to account for the skewed nature of the data, we calculated 95% confidence intervals for differential costs using the nonparametric bootstrap method. Methotrexate was £1179 (CI 819-1550) per patient cheaper than surgery but there were no significant savings with methotrexate in women with hCG >1500 IU/L due to treatment failures. Our data support an ongoing unmet economic need for better medical treatments for EP with hCG >1500 IU/L.

Methods We conducted a retrospective cost analysis on women treated for EP in a large UK teaching hospital to (1 investigate whether the cost of medical management is less expensive than surgical management for those patients eligible for both treatments and (2 to compare the cost of medical management for women with hCG concentrations 1500–3000 IU/L against those with similar hCG concentrations that elected for surgery. Three distinct treatment groups were identified: (1 those who had initial medical management with methotrexate, (2 those who were eligible for initial medical management but chose surgery (‘elected’ surgery and (3 those who initially ‘required’ surgery and did not meet the eligibility criteria for methotrexate. We calculated the costs from the point of view of the National Health Service (NHS in the UK. We summarised the cost per study group using the mean, standard deviation, median and range and, to account for the skewed nature of the data, we calculated 95% confidence intervals for differential costs using the nonparametric bootstrap method. Results Methotrexate was £1179 (CI 819–1550 per patient cheaper than surgery but there were no significant savings with methotrexate in women with hCG >1500 IU/L due to treatment failures. Conclusions Our data support an ongoing unmet economic need for better medical treatments for EP with hCG >1500 IU/L.

  4. Tape recorded hypnosis in oral and maxillofacial surgery--basics and first clinical experience. (United States)

    Hermes, Dirk; Truebger, Daniel; Hakim, Samer George; Sieg, Peter


    Surgical treatment of diseases of the oral and maxillofacial region under local anaesthesia is quite commonly restricted by limited patient compliance. 'Medical Hypnosis' could be an alternative to treatment under pharmacological sedation. With this method, both autosuggestive and other suggestive procedures are used for anxiolysis, relaxation, sedation and analgesia of the patient. The purpose of this paper was to see whether there could be any potential for this treatment when operating on oral and maxillofacial patients. During a 1-year-trial period, 209 operations under combined local anaesthesia/medical hypnosis were carried out on 174 non-preselected patients between the ages of 13 and 87 years. The surgical range covered oral, plastic and reconstructive, oncological, septic and trauma operations. Medical hypnosis turned out to be a reliable and standardizable method with high patient compliance. Remarkable improvements in treatment conditions for both patient and surgeons were achieved in 93% of cases. Controlled clinical studies are now necessary to obtain objective data on the effectiveness of hypnosis-induced intraoperative effects in oral and maxillofacial surgery.

    We examined 39 cases (1.6%) of post-operative brain damages out of 2,445 sequential cases of cardiovascular surgery in NCVC during past three years. In this study, we investigated clinical course and CT findings of each patient in details and analyzed the causes of the post operative brain damages. Of 39 cases, 23 (59%) were complicated with cerebral ischemia, 8 (21%) with subdural hematoma (SDH), 2 (5%) with intracranial hemorrhage (ICH) and 1 (2%) with subarachnoid hemorrhage (SAH), respectively. 5 cases (13%) had unclassified brain damages. In 23 cases of cerebral ischemia there were 5 cases of hypotension-induced ischemia, 4 cases of hypoxic encephalopathy, 3 cases of ischemia induced by intra-operative maneuvers, 3 cases of embolism after operation and a single case of 'microembolism'. Seven cases could not be classified into any of these categories. Duration of ECC was 169.9 {plus minus} 48.5 min on the average in patients with such brain damages as SDH, ICH, SAH and cardiogenic embolism, which were thought not to be related with ECC. On the other hand, that of the patients hypotensive ischemia or 'microembolism' gave an average value of 254.5 {plus minus} 96.8 min. And these patients were thought to have occurred during ECC. There was a statistically significant difference between these two mean values. (J.P.N.).

    The aim of this clinical trial is to evaluate the influence of high and low ligation of the inferior mesenteric artery with apical lymph node dissection on the anastomotic blood supply, lymph node retrieval rate, operative time and anastomotic leakage rate in rectal cancer surgery. A total of 57 Chinese patients were randomly distributed into group A and group B and underwent radical resection of rectal cancer. Patients in group A underwent high ligation of the inferior mesenteric artery, and patients in group B underwent apical lymph node resection around the root of the inferior mesenteric artery with preservation of the left colic artery. The marginal artery stump pressure was measured after colon and artery reconstruction. Systemic pressure, distal colon length, operative time and lymph node retrieval rate were measured and recorded. The results were analysed and related to patient characteristics and post-operative complications. The anastomotic blood supply negatively and linearly correlated with age and distal colon length and showed a positive linear correlation with systemic pressure. Patients who received low ligation with apical lymph node dissection had a better anastomotic blood supply than those who received high ligation. No differences were found in lymph node retrieval rate, operative time and anastomotic leakage rate. Anastomotic leakage was associated with a worse anastomotic blood supply. Low ligation with apical lymph node dissection in rectal cancer treatment provides better anastomotic blood supply but is not associated with differences in node retrieval rate or operation time. © 2015 Royal Australasian College of Surgeons.

  7. [Predictive methods versus clinical titration for the initiation of lithium therapy. A systematic review]. (United States)

    Geeraerts, I; Sienaert, P


    When lithium is administered, the clinician needs to know when the lithium in the patient’s blood has reached a therapeutic level. At the initiation of treatment the level is usually achieved gradually through the application of the titration method. In order to increase the efficacy of this procedure several methods for dosing lithium and for predicting lithium levels have been developed. To conduct a systematic review of the publications relating to the various methods for dosing lithium or predicting lithium levels at the initiation of therapy. We searched Medline systematically for articles published in English, French or Dutch between 1966 and April 2012 which described or studied a method for dosing lithium or for predicting the lithium level reached following a specific dosage. We screened the reference lists of relevant articles in order to locate additional papers. We found 38 lithium prediction methods, in addition to the clinical titration method. These methods can be divided into two categories: the ‘a priori’ methods and the ‘test-dose’ methods, the latter requiring the administration of a test dose of lithium. The lithium prediction methods generally achieve a therapeutic blood level faster than the clinical titration method, but none of the methods achieves convincing results. On the basis of our review, we propose that the titration method should be used as the standard method in clinical practice.

    Mateo-Negreira, J; López-Cuello, P; Pipa-Muñiz, I; Rodríguez García, N; Murcia-Mazón, A; Suárez-Suárez, M A


    Long term clinical and radiological evaluation of results, survival, and peri- operative and post-operative complications of the patients who have been operated on for revision total hip arthroplasty using the impaction allografting and cemented rod technique. An observational, analytical, prospective and non-random study was conducted on 26 patients who underwent revision total hip arthroplasty in our Hospital (1997-98). They were clinically and radiologically assessed, and a survival analysis of the implant was performed. Statistically significant differences were identified in the pre- and post-operative values, according to Harris and Merle D́Aubigne scores. The femoral components survival was considered as an endpoint of the revision replacement, which was 84% at a mean of 13 years. There were 9 intraoperative complications (6 were fractures) and they significantly affected the length of hospital stay. No post-operative complications were observed in 70% of the patients. None of the analysed variables had any influence on the radiological subsidence of the femoral component. Several techniques aim to solve the bone stock deficiency in revision total hip arthroplasty, but only impaction grafting attempts to recover it. The Ling's technique shows an improvement over the Merle D́Aubigne and Harris scores, in the medium-long term. The intraoperative complications are mainly an increase in the length of hospital stay and the number of days needed to be able to sit down. Ling's technique is a good option to consider in young patients where it is foreseeable that there is a new revision surgery in the future. Copyright © 2015 SECOT. Published by Elsevier Espana.

    Omidi-Kashani, Farzad; Hootkani, Alireza; Jarahi, Lida; Rezvan, Manizheh; Moayedpour, Amir


    Surgical techniques used in the treatment of patients with high grade lumbar spondylolisthesis (> 50% slippage) are usually associated with a great deal of controversies. We aim to evaluate the surgical outcomes of high grade spondylolisthesis treated with an intraoperative temporary distraction rod. We retrospectively studied 21 patients (14 females and 7 males), aged 50.4 ± 9.2 years, who had high grade lumbar spondylolisthesis that was treated with intraoperative temporary distraction rods, neural decompression, pedicular screw fixation, and posterolateral fusion involving one more intact upper vertebra. The mean follow-up period was 39.2 months. Radiologic and clinical outcomes were measured by slip angle, slip percentage, correction rate, Oswestry Disability Index (ODI), visual analogue scale (VAS), patient's satisfaction rate in the pre- and postoperative period. Data were analyzed by SPSS ver. 11.5. Analysis of the preoperative visits and final follow-up visits indicated that surgery could improve ODI, lumbar VAS, and leg VAS from 60.5% to 8.2%, from 6.7 to 2.2, and from 6.9 to 1.3, respectively. Slip angle and slip percentage were also changed from -8° to -15° and from 59.2% to 21.4%, respectively. Mean correction rate at the final follow-up visit was 64.1%. Loss of correction was insignificant and a neurologic complication occurred in one patient due to misplacement of one screw. Excellent and good levels of satisfaction were observed in 90.5% of the patients. In the surgical treatment of refractory high grade spondylolisthesis, the use of a temporary distraction rod to reduce the slipped vertebra in combination with neural decompression, posterolateral fusion, and longer instrumentation is associated with satisfactory clinical and radiologic outcomes.

  12. The disparity of frontline clinical staff and managers' perceptions of a quality and patient safety initiative. (United States)

    Parand, Anam; Burnett, Susan; Benn, Jonathan; Pinto, Anna; Iskander, Sandra; Vincent, Charles


    Arguably, a shared perspective between managers and their clinical staff on an improvement initiative would allow for most effective implementation and increase programme success. However, it has been reported that research has failed to differentiate between managers and line employees on quality management implementation and examine their differences in perceptions of quality and safety initiatives. The aim of this study was to compare clinical frontline staff and senior managers' perceptions on the importance of an organization-wide quality and safety collaborative: the Safer Patients Initiative (SPI). A quantitative study obtained 635 surveys at 20 trusts participating in SPI. Participants included the teams and frontline staff involved within the programme at each organization. Independent T-tests were carried out between frontline staff and senior managers' perceptions of SPI programme elements, success factors and impact & sustainability. Statistically significant differences were found between the perceptions of frontline staff and senior managers on a wide number of issues, including the frontline perceiving a significantly larger improvement on the timeliness of care delivery (t = 2.943, P = 0.004), while managers perceived larger improvement on the culture within the organization for safe, effective and reliable care (t = -2.454, P = 0.014). This study has identified statistically significant disparities in perceptions of an organization-wide improvement initiative between frontline staff and senior managers. This holds valuable implications for the importance of getting both frontline and management perspectives when designing such interventions, in monitoring their performance, and in evaluating their impact. © 2010 Blackwell Publishing Ltd.

  13. "Salvage microbiology": detection of bacteria directly from clinical specimens following initiation of antimicrobial treatment.

    Directory of Open Access Journals (Sweden)

    John J Farrell

    Full Text Available PCR coupled with electrospray ionization mass spectrometry (ESI-MS is a diagnostic approach that has demonstrated the capacity to detect pathogenic organisms from culture negative clinical samples after antibiotic treatment has been initiated. [1] We describe the application of PCR/ESI-MS for detection of bacteria in original patient specimens that were obtained after administration of antibiotic treatment in an open investigation analysis.We prospectively identified cases of suspected bacterial infection in which cultures were not obtained until after the initiation of antimicrobial treatment. PCR/ESI-MS was performed on 76 clinical specimens that were submitted for conventional microbiology testing from 47 patients receiving antimicrobial treatment.In our series, 72% (55/76 of cultures obtained following initiation of antimicrobial treatment were non-diagnostic (45 negative cultures; and 10 respiratory specimens with normal flora (5, yeast (4, or coagulase-negative staphylococcus (1. PCR/ESR-MS detected organisms in 83% (39/47 of cases and 76% (58/76 of the specimens. Bacterial pathogens were detected by PCR/ESI-MS in 60% (27/45 of the specimens in which cultures were negative. Notably, in two cases of relapse of prosthetic knee infections in patients on chronic suppressive antibiotics, the previous organism was not recovered in tissue cultures taken during extraction of the infected knee prostheses, but was detected by PCR/ESI-MS.Molecular methods that rely on nucleic acid amplification may offer a unique advantage in the detection of pathogens collected after initiation of antimicrobial treatment and may provide an opportunity to target antimicrobial therapy and "salvage" both individual treatment regimens as well as, in select cases, institutional antimicrobial stewardship efforts.

  14. Accuracy of administrative and clinical registry data in reporting postoperative complications after surgery for oral cavity squamous cell carcinoma. (United States)

    Awad, Mahmoud I; Shuman, Andrew G; Montero, Pablo H; Palmer, Frank L; Shah, Jatin P; Patel, Snehal G


    The purpose of this study was to describe and compare how postoperative complications after oral cavity squamous cell carcinoma (SCC) surgery are reported in medical records, institutional billing claims, and national clinical registries. The medical records of 355 previously untreated patients who underwent surgery for oral cavity SCC at our institution were retrospectively reviewed for postoperative complications. Information was compared with claims and National Surgical Quality Improvement Program (NSQIP) data. We identified 219 patients (62%) experiencing 544 complications (10% major). Billing claims identified 29% of these patients, 36% of overall complications, and 98% of major complications. Of overlapping patients, NSQIP identified 27% of patients, 33% of overall complications, and 100% of major complications noted on chart abstraction. The incidence of minor postoperative complications after oral cavity SCC surgery is relatively high. Both claims data and NSQIP accurately recorded major complications, but were suboptimal compared to chart abstraction in capturing minor complications. © 2014 Wiley Periodicals, Inc.

  15. Clinical application of the Nd-YAG and Ho-YAG lasers in otolaryngology: head and neck surgery (United States)

    Kukwa, Andrzej; Tulibacki, Marek P.; Dudziec, Katarzyna; Wojtowicz, Piotr


    The authors present their clinical experience regarding the possibilities of application of Nd:YAG and Ho:YAG lasers for the treatment of disorders in the area of the upper respiratory tract sinuses and ears. This technique makes it possible to perform a number of procedures in local anesthesia which considerably improves the economic effectiveness of the treatment. In case of the Nd:YAG laser they have also utilized the effect of deep coagulation of the soft tissues, whereas the Ho:YAG laser energy was applied for the surgery of bone tissue. The surgeries performed using laser beam enabled very good effect of treatment. They are competitive compared wit the methods used by traditional surgery.

    Lefranc, Michel; Zouitina, Yassine; Tir, Mélissa; Merle, Philippe; Ouendo, Martial; Constans, Jean-Marc; Godefroy, Olivier; Peltier, Johann; Krystkowiak, Pierre


    To study the impact of not performing awake clinical evaluation during the robot-assisted implantation of subthalamic nucleus deep brain stimulation (STN-DBS) electrodes on the stimulation parameters and clinical outcomes in patients with Parkinson disease (PD). A total of 23 patients with PD underwent robot-assisted surgery for the bilateral implantation of STN-DBS electrodes. Thirteen patients received general anesthesia (GA) and a limited intraoperative evaluation (side effects only), and the other 10 patients received local anesthesia (LA) and a full evaluation. The primary endpoint was the therapeutic window (TW), defined as the difference between the mean voltage threshold for motor improvement and the mean voltage threshold for side effects in the active contacts at 12 months after surgery. Motor scores were measured as well. The TW was similar in the LA and GA groups, with mean ± standard deviation values of 2.06 ± 0.53 V and 2.28 ± 0.99 V, respectively (P = 0.32). In the short term, the Unified Parkinson Disease Rating Scale (UPDRS) III score in the "off-drug, on-stim" condition fell to a similar extent in the LA and GA groups (by 40.3% and 49%, respectively; P = 0.336), as did the UPDRS III score in the "on-stim, on-drug" condition (by 57% and 70.7%, respectively; P = 0.36). Asleep, robot-assisted implantation of STN-DBS electrodes (with accurate identification of the STN and positioning of the DBS lead) produced the same motor results and TW as awake surgery.

  20. Contribution of clinical gait analysis to single-event multi-level surgery in children with cerebral palsy. (United States)

    Khouri, N; Desailly, E


    Clinical gait analysis (CGA) has been proven useful in understanding the gait disturbances seen in children and adolescents with cerebral palsy. Another major benefit provided by CGA is a clinical and scientific evaluation of how orthopaedic surgical procedures modify gait. The information provided by instrumented CGA complements the clinical data, and the two must be interpreted jointly. Although there is some variability in the surgical details of therapeutic strategies, CGA undoubtedly influences the planning of surgery. Although CGA improves surgical outcomes, these remain challenging to predict. CGA seems cost-effective. Internal hip rotation gait is used as an example to illustrate those benefits.

  1. Oral Anticoagulant Use After Bariatric Surgery: A Literature Review and Clinical Guidance. (United States)

    Martin, Karlyn A; Lee, Craig R; Farrell, Timothy M; Moll, Stephan


    Bariatric surgery may alter the absorption, distribution, metabolism, or elimination (disposition) of orally administered drugs via changes to the gastrointestinal tract anatomy, body weight, and adipose tissue composition. As some patients who have undergone bariatric surgery will need therapeutic anticoagulation for various indications, appropriate knowledge is needed regarding anticoagulant drug disposition and resulting efficacy and safety in this population. We review general considerations about oral drug disposition in patients after bariatric surgery, as well as existing literature on oral anticoagulation after bariatric surgery. Overall, available evidence on therapeutic anticoagulation is very limited, and individual drug studies are necessary to learn how to safely and effectively use the direct oral anticoagulants. Given the sparsity of currently available data, it appears most prudent to use warfarin with international normalized ratio monitoring, and not direct oral anticoagulants, when full-dose anticoagulation is needed after bariatric surgery.

  2. Clinical outcome in relation to timing of surgery in chronic pancreatitis: a nomogram to predict pain relief. (United States)

    Ahmed Ali, Usama; Nieuwenhuijs, Vincent B; van Eijck, Casper H; Gooszen, Hein G; van Dam, Ronald M; Busch, Olivier R; Dijkgraaf, Marcel G W; Mauritz, Femke A; Jens, Sjoerd; Mast, Jay; van Goor, Harry; Boermeester, Marja A


    To evaluate the effect of timing of surgery on the long-term clinical outcome of surgery in chronic pancreatitis (CP). Cohort study with long-term follow-up. Five specialized academic centers. Patients with CP treated surgically for pain. Pancreatic resection and drainage procedures for pain relief. Pain relief (pain visual analogue score ≤4), pancreatic function, and quality of life. We included 266 patients with median follow-up of 62 months (interquartile range, 31-112). Results were presented as odds ratios (ORs)with 95% confidence intervals after correction for bias using bootstrap-corrected analysis. Pain relief was achieved in 149 patients (58%). Surgery within 3 years of symptoms was independently associated with more pain relief (OR, 1.8; 95% CI, 1.0-3.4; P = .03) and less endocrine pancreatic insufficiency (OR, 0.57; 95% CI, 0.33-0.96; P = .04). More pain relief was also observed in patients not taking opioids preoperatively (OR, 2.1; 95% CI, 1.2-4.0; P = .006) and who had 5 or fewer endoscopic treatments prior to surgery (OR, 2.5; 95% CI, 1.1-6.3; P = .04). The probability of achieving pain relief varied between 23% and 75%, depending on these risk factors. The timing of surgery is an important risk factor for clinical outcome in CP. Surgery may need to be considered at an earlier phase than it is now, preferably within 3 years of symptomatic CP. Likelihood of postoperative pain relief can be calculated on an individual basis using the presented nomogram.

    To examine the extent to which a clinical intervention resulted in reduced BMI z scores among 2- to 12-year-old children compared to routine practice (treatment as usual [TAU]). The Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project is a multifaceted initiative to prevent childhood obesity among low-income children. At the federally qualified community health centers (FQHCs) of two communities (Intervention Site #1 and #2), the following were implemented: (1) pediatric weight management training, (2) electronic decision supports for clinicians, (3) on-site Healthy Weight Clinics, (4) community health worker integration, and (5) healthful clinical environment changes. One FQHC in a demographically matched community served as the TAU site. Using electronic health records, we assessed BMI z scores and used linear mixed models to examine BMI z score change over 2 years in each intervention site compared to a TAU site. Compared to children in the TAU site (n = 2,286), children in Intervention Site #2 (n = 1,368) had a significant decline in BMI z scores following the start of the intervention (-0.16 units/y; 95% confidence interval: -0.21 to -0.12). No evidence of an effect was found in Intervention Site #1 (n = 111). The MA-CORD clinical interventions were associated with modest improvement in BMI z scores in one of two intervention communities compared to a TAU community. © 2017 The Obesity Society.

  7. Comparison between prostaglandin E1, and esmolol infusions in controlled hypotension during scoliosis correction surgery a clinical trial. (United States)

    Goma, Hala Mostafa


    scoliosis correction surgery is common in children, and adolescents. Deliberate hypotension is indicated in scoliosis correction procedures, because bloodless field is needed for exposure of the nerve roots, and to decrease the need for blood transfusion. Protection of the kidneys during deliberate hypotension is essential. The ideal hypotensive drug maintains the renal function and the urine output during the period of hypotension. Aim of this study is to compare Prostaglandin E1, and Esmolol hypotensive effects, bleeding score, and their effects on the serum creatnine, and urine output. Twenty patients under went hypotensive anesthesia during scoliosis correction procedure, were enrolled in this clinical trial. In group 1 (n = 10) (Esmolol infusion), group 2 (n = 10) (prostaglandin E1 infusion), Parameters were measured: Mean arterial blood pressure, Heart rate, (preoperative, just after induction, 15 minutes, 30 minutes, 60 minutes after starting the infusions, and 15 minutes after discontinuation of infusions). The bleeding score was assessed at (15 minutes, 30 minutes, 60 minutes after starting the infusions). heart rate was significantly higher in prostaglandin E1 group than Esmolol group at 15, 30, 45, and 60 minutes. There was significant difference in the bleeding score only after 30 minutes, The target mean blood pressure (50 mmHg) was achieved at 30 minutes in group 2 (prostaglandin E1), while it was achieved at 60 minutes in group 1 (Esmolol group). There were significant differences in Mean blood pressure between both groups at 15, 30, 45, 60 minutes after starting the infusions. Creatnine level was significantly lower in prostaglandin E1 group, while the introperative urine output was significantly higher in prostaglandin E1 group. Prostaglandin E1 hypotensive effects started earlier than Esmolol and its bleeding score is better than esmolol especially at thirty minutes after initiation of the infusion. Prostaglandin E1 can maintain renal function and

    The purpose of this study was to evaluate the clinical effect on the biochemical inflammatory markers of a single oral high dose of cholecalciferol in vitamin D-deficient patients undergoing the surgical removal of lower third molars.A randomized, split-mouth, single-blind study was conducted on 25 vitamin D-deficient patients ranging between 18 and 40 years of age requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina.All patients, with vitamin D3 blood levels ≦30 ng/mL, underwent bilateral surgical removal. The first extraction (control group) being conducted with the administration of a placebo, the second one (test group) being conducted with the preliminary administration of 300,000 IU of cholecalciferol 4 days before the procedure.At each surgery, clinical indexes, such as pain, edema and any functional limitation have been recorded. Clinical and biochemical parameters were registered 4 days before, immediately after, 3 and 7 days after the surgical procedure. The data obtained were processed using paired t-test. The clinical outcome parameters showed a slight to moderate improvement between the control and the vitamin-D treatment group, with statistical significance being obtained regarding the edema at defined time points. Interleukin-1-beta, interleukin-6, and tumor necrosis factor-alpha values were significantly lower (P surgery. The increase of vitamin D serum levels showed an impact on the outcome of the third molar surgery, eliciting a reduced inflammatory response and leading to a more favorable clinical course.

    Liu, Wen P.; Mirota, Daniel J.; Uneri, Ali; Otake, Yoshito; Hager, Gregory; Reh, Douglas D.; Ishii, Masaru; Gallia, Gary L.; Siewerdsen, Jeffrey H.


    Augmentation of endoscopic video with preoperative or intraoperative image data [e.g., planning data and/or anatomical segmentations defined in computed tomography (CT) and magnetic resonance (MR)], can improve navigation, spatial orientation, confidence, and tissue resection in skull base surgery, especially with respect to critical neurovascular structures that may be difficult to visualize in the video scene. This paper presents the engineering and evaluation of a video augmentation system for endoscopic skull base surgery translated to use in a clinical study. Extension of previous research yielded a practical system with a modular design that can be applied to other endoscopic surgeries, including orthopedic, abdominal, and thoracic procedures. A clinical pilot study is underway to assess feasibility and benefit to surgical performance by overlaying CT or MR planning data in realtime, high-definition endoscopic video. Preoperative planning included segmentation of the carotid arteries, optic nerves, and surgical target volume (e.g., tumor). An automated camera calibration process was developed that demonstrates mean re-projection accuracy (0.7+/-0.3) pixels and mean target registration error of (2.3+/-1.5) mm. An IRB-approved clinical study involving fifteen patients undergoing skull base tumor surgery is underway in which each surgery includes the experimental video-CT system deployed in parallel to the standard-of-care (unaugmented) video display. Questionnaires distributed to one neurosurgeon and two otolaryngologists are used to assess primary outcome measures regarding the benefit to surgical confidence in localizing critical structures and targets by means of video overlay during surgical approach, resection, and reconstruction.

  10. Chest radiography in the initial episode of bronchospasm in children: can clinical variables predict pathologic findings? (United States)

    Walsh-Kelly, C M; Kim, M K; Hennes, H M


    To determine whether historical or clinical variables can accurately discriminate among children, experiencing a first episode of bronchospasm, with chest radiography findings that are normal, consistent with reactive airway disease (RAD), or pathologic. We assembled a prospective case series of patients in our tertiary, academic, pediatric emergency department. All patients aged newborn to 18 years presenting to the ED with their initial episode of wheezing were enrolled. Six hundred thirty-three patients presented to the ED during the study period. Pathologic radiographic findings were identified in 39 (6.2%). Radiographs revealing normal findings and evidence of RAD were noted in 25.4% and 68%, respectively. No single variable accurately predicted all pathologic radiographs. Discriminant function analysis identified nine variables, which we combined into a model. The model failed to accurately discriminate among patients with radiographs revealing evidence of a pathologic condition, normal chest findings, and RAD. No clinical variables, isolated or combined into a model, accurately identify patients with pathologic radiography findings. Continued use of chest radiography as a diagnostic intervention in the initial episode of childhood bronchospasm is recommended.

    Diffuse pulmonary alveolar hemorrhage (DAH) is caused by various disorders and is a medical emergency that often results in acute respiratory failure requiring prompt diagnosis and aggressive treatment. However, the relationships between the prognosis and the initial clinical feature in DAH remain unclear. We investigated the relationships between initial clinical features and prognosis in 14 cases of DAH. We examined 14 patients with DAH about laboratory data, CT scan findings, treatment and outcome. Three of 14 patients died of acute respiratory failure due to DAH. In the laboratory data on admission, the patients with over 230 IU/L of serum lactate dehydrogenase (LDH) levels had a poor outcome. In pulmonary function data on admission, the patients with under 300 of PaO 2 /FiO 2 (P/F) ratio had poor outcome. On CT scan findings on admission, the patients with consolidation shadows had a poor outcome compared to the patients with ground-glass shadows. In our data, serum LDH concentration, P/F ratio and CT scan findings on admission are important factors in the prognosis of DAH. (author)

  15. Clinical trials to reduce pancreatic fistula after pancreatic surgery-review of randomized controlled trials. (United States)

    Kitahata, Yuji; Kawai, Manabu; Yamaue, Hiroki


    Pancreatic fistula is one of severe postoperative complications that occur after pancreatic surgery, such as pancreaticoduodenectomy (PD) and distal pancreatectomy (DP). Because pancreatic fistula is associated with a higher incidence of life-threatening complications. In order to evaluate procedure or postoperative management to reduce pancreatic fistula after pancreatic surgery, we summarized some randomized controlled trials (RCTs) regarding pancreaticoenterostomy during PD, pancreatic duct stent during PD, procedure to resect pancreatic parenchyma during DP, and somatostatin and somatostatin analogues after pancreatic surgery. At first, we reviewed nine RCTs to compare pancreaticogastrostomy (PG) with pancreaticojejunostomy (PJ) during PD. Next, we reviewed five RCTs, to evaluate the impact of pancreatic duct stent during PD. Regarding DP, we reviewed six RCTs to evaluate appropriate procedure to reduce pancreatic fistula after DP. Finally, we reviewed eight RCTs to evaluate the impact of somatostatin and somatostatin analogues after pancreatic surgery to reduce pancreatic fistula. The best way to prevent pancreatic fistula after pancreatic surgery remains still controversial. However, several RCTs clarify a useful procedure to reduce in reducing the incidence of pancreatic fistula after pancreatic surgery. Further RCTs to study innovative approaches remain a high priority for pancreatic surgeons to prevent pancreatic fistula after pancreatic surgery.

    To illustrate the reliability of the Pang-Rotenberg (PR) sign as a prognosticator of snoring surgery. Our hypothesis was that patients who are PR-positive have better snoring reduction scores and outcomes than PR-negative patients after nose and palate surgery. A multicenter prospective series of 153 patients with snoring. All patients graded the snoring intensity on a visual analog scale (VAS). All 137 patients enrolled had both the nose surgery and palate surgery. The control group consisted of 16 patients who underwent nasal surgery alone. There were 122 men and 15 women, the mean age was 44.6 years old, and mean body mass index was 26.1. There were 15 simple snorers and 122 obstructive sleep apnea patients. Patients who were PR-positive showed significantly better postoperative snoring VAS reduction (from 9.04 to 1.02) compared to those patients who were PR-negative (from 8.91 to 3.14) (P snoring VAS reduction from 9.21 to 6.72. After adjusting for covariates that influence the snoring VAS change due to surgery, we found that PR-negative patients achieved an average of 5.78 improvement in snoring VAS, whereas PR-positive patients achieved an average of 8.02 improvement in snoring VAS (P snoring reduction, after combined nose and palate surgery, for patients with troublesome snoring. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

  17. Clinical considerations in the use of forced-air warming blankets during orthognathic surgery to avoid postanesthetic shivering (United States)

    Park, Fiona Daye; Park, Sookyung; Chi, Seong-In; Kim, Hyun Jeong; Kim, Hye-Jung; Han, Jin-Hee; Han, Hee-Jeong; Lee, Eun-Hee


    Background During head and neck surgery including orthognathic surgery, mild intraoperative hypothermia occurs frequently. Hypothermia is associated with postanesthetic shivering, which may increase the risk of other postoperative complications. To improve intraoperative thermoregulation, devices such as forced-air warming blankets can be applied. This study aimed to evaluate the effect of supplemental forced-air warming blankets in preventing postanesthetic shivering. Methods This retrospective study included 113 patients who underwent orthognathic surgery between March and September 2015. According to the active warming method utilized during surgery, patients were divided into two groups: Group W (n = 55), circulating-water mattress; and Group F (n = 58), circulating-water mattress and forced-air warming blanket. Surgical notes and anesthesia and recovery room records were evaluated. Results Initial axillary temperatures did not significantly differ between groups (Group W = 35.9 ± 0.7℃, Group F = 35.8 ± 0.6℃). However, at the end of surgery, the temperatures in Group W were significantly lower than those in Group F (35.2 ± 0.5℃ and 36.2 ± 0.5℃, respectively, P = 0.04). The average body temperatures in Groups W and F were, respectively, 35.9 ± 0.5℃ and 36.2 ± 0.5℃ (P = 0.0001). In Group W, 24 patients (43.6%) experienced postanesthetic shivering, while in Group F, only 12 (20.7%) patients required treatment for postanesthetic shivering (P = 0.009, odds ratio = 0.333, 95% confidence interval: 0.147–0.772). Conclusions Additional use of forced-air warming blankets in orthognathic surgery was superior in maintaining normothermia and reduced the incidence of postanesthetic shivering. PMID:28879279

    Full Text Available Aim: Percutaneous endoscopic gastrostomy is the most preferable procedure for nutritional support in patients starving for a long time, who have difficulty in swallowing or feeding by oral way due to various diseases. The five years%u2019 experience of this surgery clinic was obtained in this study. Material and Method: The indications, complications and long term follow-up were recorded by physicians for 197 patients who had undergone percutaneous endoscopic gastrostomy. We used standart pull method for lite application of gastrostomy. Results: Percutaneous endoscopic gastrostomy was performed successfully in 141 (%71 chronic neurological patients, 35 (%17 patients with malignancy and 21 (%10 patients with various diseases with especially long time ventilation. It was performed on 141 male and 56 female patients, with a median age of 52.7 years (range 14-93 years. One hundred thirdy nine (total mortality 71% patients died because of the primary disease and after being discharged from the hospital. There was no mortality attributable to the procedure. The median time the patients used percutaneous endoscopic gastrostomy was 101.4 days (range 1-322 days excluding 37 (19% patients in whom the communication was lost during follow-up. There were a catheter leakage early in 34 and later in 19 patients, unsettled cathether in 6 patients, obstruction in 8 patients and catheter area inflamation in patients. PEG was performed twice in 7 patients. Discussion: Percutaneous endoscopic gastrostomy is a safe and reliable procedure for enteral feeding. The important complications are generally related to catheter care. In order to reduce complicatoins in the long run, further education of caretakers of patients and organization of the nutrition outpatient unit is advisable.

  19. Video-Assisted Thoracoscopic Surgery in Patients With Clinically Resectable Lung Tumors

    Directory of Open Access Journals (Sweden)

    H. Sakai


    Full Text Available To investigate the feasibility of thoracoscopic resection, a pilot study was performed in patients with clinically resectable lung tumors. In 40 patients, Video-assisted thoracic surgery (VATS was performed because of suspicion of malignancy. There were 29 men and 11 women with a median age of 54.8 years (range 18 to 78. Preoperative indications were suspected lung cancer and tumor in 27 patients, assessment of tumor resectability in 7 patients, and probability of metastatic tumors in 6 patients. The final diagnoses in the 27 patients with suspected lung cancer were 12 primary lung cancers, 6 lung metastases, and 9 benign lesions. The success rates for VATS (no conversion to thoracotomy were 1 of 12 (8.3% for resectable stage I lung cancer, 8 of 12 (66.7% for metastatic tumors, and 9 of 9 (100% for benign tumors. With VATS, 6 of 7 patients (85.7%, possible stage III non-small cell lung cancer, an explorative thoracotomy with was avoided, significantly reducing morbidity. The reasons for conversion to thoracotomy were 1 oncological (N2 lymph node dissection and prevention of tumor spillage and 2 technical (inability to locate the nodule, central localization, no anatomical fissure, or poor lung function requiring full lung ventilation. The ultimate diagnoses were 19 lung cancers, 12 metastatic lung tumors, and 9 benign lung tumors. Our data show the limitations of VATS for malignant tumors in general use. These findings, together with the fact that experience in performing thoracoscopic procedures demonstrates a learning curve, may limit the use of thoracoscopic resection as a routine surgical procedure, especially when strict oncological rules are respected.

    Elmistekawy, Elsayed; Gee, Yen-Yen; Une, Dai; Lemay, Matthieu; Stolarik, Anne; Rubens, Fraser D


    Temporary pacemaker wires are placed in the majority of patients after cardiac surgery. There is no information on mechanical factors related to wire removal. Clinical information related to temporary wire use and removal was prospectively collected from a large cardiac surgical unit over one year. Measurements of maximal tension that nurses and doctors would apply to remove temporary wires was determined using a hand-held portable scale. In a prospective trial, patients (n = 41) had their wires extracted in series to the portable scale to determine the maximal tension required for safe removal. Ventricular wires were placed in 86.5 % of patients during the observed year. Pacing facilitated weaning from CPB in over 15 % of patients and pacer dependence was seen in 2.1 %. No patients suffered major complications after wire removal. There was no difference in the tension that physicians or nurses would apply to comfortably extract temporary wires. In the prospective trial, there was no difference in the tension required for removal of atrial or ventricular wires (atrial 18.3 ± 17.9 oz versus 14.5 ± 14.2 oz, p = 0.430). There were no patient factors that correlated with the degree of resistance and there was no significant difference between the tension required to remove wires with (21.0 ± 22.5 oz) or without (14.1 ± 5.1 oz) an atrial button. Temporary epicardial wire removal is innocuous and was not associated with any complications. In some patients tension required for safe removal exceeded 20 ounces. Strategies to standardize wire removal may prevent complications and may minimize unnecessary wire retention.

    Freundlich, Robert E; Ehrenfeld, Jesse M


    A variety of existing perioperative informatics tools offer clinicians and researchers the opportunity to improve the delivery of care and clinical outcomes for patients undergoing cardiac and vascular surgery. Many of these tools can be used to improve the reliability of the care delivery process through the application of clinical decision support tools and/or quality improvement methodologies at a number of junctures. In this review, the authors will offer a concise overview of the existing perioperative informatics literature, with a focus on tools considered to be of utility in confronting the unique challenges inherent to cardiac and vascular surgery. The authors also highlight areas that they believe are of interest for future targeted inquiry. Copyright © 2017 Elsevier Inc. All rights reserved.

    To examine the clinical and ultrasonographic (US) outcomes of reducing methotrexate (MTX) dosage upon initiating adalimumab (ADA) in MTX-inadequate responders with moderately to severely active rheumatoid arthritis (RA). MUSICA (NCT01185288) was a double-blind, randomized, parallel-arm study of 309 patients with RA receiving MTX ≥ 15 mg/week for ≥ 12 weeks before screening. Patients were randomized to high dosage (20 mg/week) or low dosage (7.5 mg/week) MTX; all patients received 40 mg open-label ADA every other week for 24 weeks. The primary endpoint was Week 24 mean 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP) to test for noninferiority of low-dosage MTX using a 15% margin. US images were scored using a 10-joint semiquantitative system incorporating OMERACT definitions for pathology, assessing synovial hypertrophy, vascularity, and bony erosions. Rapid improvement in clinical indices was observed in both groups after addition of ADA. The difference in mean DAS28-CRP (0.37, 95% CI 0.07-0.66) comparing low-dosage (4.12, 95% CI 3.88-4.34) versus high-dosage MTX (3.75, 95% CI 3.52-3.97) was statistically significant and non-inferiority was not met. Statistically significant differences were not detected for most clinical, functional, and US outcomes. Pharmacokinetic and safety profiles were similar. In MUSICA, Week 24 mean DAS28-CRP, the primary endpoint, did not meet non-inferiority for the low-dosage MTX group. Although the differences between the 2 MTX dosage groups were small, our study findings did not support routine MTX reduction in MTX inadequate responders initiating ADA.

    Love, Kaitlin M; Mehaffey, J Hunter; Safavian, Dana; Schirmer, Bruce; Malin, Steven K; Hallowell, Peter T; Kirby, Jennifer L


    Many insurance companies have considerable prebariatric surgery requirements despite a lack of evidence for improved clinical outcomes. The hypothesis of this study is that insurance-specific requirements will be associated with a decreased progression to surgery and increased delay in time to surgery. Retrospective data collection was performed for patients undergoing bariatric surgery evaluation from 2010-2015. Patients who underwent surgery (SGY; n = 827; mean body mass index [BMI] 49.1) were compared with those who did not (no-SGY; n = 648; mean BMI: 49.4). Univariate and multivariate analysis were performed to identify specific co-morbidity and insurance specific predictors of surgical dropout and time to surgery. A total of 1475 patients using 12 major insurance payors were included. Univariate analysis found insurance requirements associated with surgical drop out included longer median diet duration (no-SGY = 6 mo; SGY = 3 mo; Psurgery dropout. Additionally, surgical patients had an average interval between initial visit and surgery of 5.8±4.6 months with significant weight gain (2.1 kg, Psurgery insurance requirements were associated with lack of patient progression to surgery in this study. In addition, delays in surgery were associated with preoperative weight gain. Although prospective and multicenter studies are needed, these findings have major policy implications suggesting insurance requirements may need to be reconsidered to improve medical care.

    . This is also confirmed by many other studies with however minor scientific evidence levels. Reduction of post-operative pain, surgical time and overall costs are discussed. Authors believe that scientific research should focus more in identifying which clinical situations can get greatest benefits from implant guided surgery. This should be done with research protocols such as RCT that assess comprehensively the advantages and disadvantages of fully digital surgical protocols.

    Liu, Ali; Wang, Jun-Mei; Li, Gui-Lin; Sun, Yi-Lin; Sun, Shi-Bin; Luo, Bin; Wang, Mei-Hua


    The goal of this study was to assess the clinical and pathological features of benign brain tumors that had been treated with Gamma Knife surgery (GKS) followed by resection. In this retrospective chart review, the authors identified 61 patients with intracranial benign tumors who had undergone neurosurgical intervention after GKS. Of these 61 patients, 27 were male and 34 were female; mean age was 49.1 years (range 19-73 years). There were 24 meningiomas, 18 schwannomas, 14 pituitary adenomas, 3 hemangioblastomas, and 2 craniopharyngiomas. The interval between GKS and craniotomy was 2-168 months, with a median of 24 months; for 7 patients, the interval was 10 years or longer. For 21 patients, a craniotomy was performed before and after GKS; in 9 patients, pathological specimens were obtained before and after GKS. A total of 29 patients underwent GKS at the Beijing Tiantan Hospital. All specimens obtained by surgical intervention underwent histopathological examination. Most patients underwent craniotomy because of tumor recurrence and/or exacerbation of clinical signs and symptoms. Neuroimaging analyses indicated tumor growth in 42 patients, hydrocephalus in 10 patients with vestibular schwannoma, cystic formation with mass effect in 7 patients, and tumor hemorrhage in 13 patients, of whom 10 had pituitary adenoma. Pathological examination demonstrated that, regardless of the type of tumor, GKS mainly induced coagulative necrosis of tumor parenchyma and stroma with some apoptosis and, ultimately, scar formation. In addition, irradiation induced vasculature stenosis and occlusion and tumor degeneration as a result of reduced blood supply. GKS-induced vasculature reaction was rarely observed in patients with pituitary adenoma. Pathological analysis of tumor specimens obtained before and after GKS did not indicate increased tumor proliferation after GKS. Radiosurgery is effective for intracranial benign tumors of small size and deep location and for tumor recurrence

    Kim, Sunkyung; Zhu, Yong; Romitti, Paul A; Fox, Deborah J; Sheehan, Daniel W; Valdez, Rodolfo; Matthews, Dennis; Barber, Brent J


    The long-term efficacy of corticosteroid treatment and timing of treatment initiation among Duchenne muscular dystrophy (DMD) patients is not well-understood. We used data from a longitudinal, population-based DMD surveillance program to examine associations between timing of treatment initiation (early childhood [before or at age 5 years], late childhood [after age 5 years], and naïve [not treated]) and five clinical outcomes (age at loss of ambulation; ages at onset of cardiomyopathy, scoliosis, and first fracture; and pulmonary function). Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using survival analysis. DMD patients who initiated corticosteroid treatment in early childhood had a higher risk of earlier onset cardiomyopathy compared to cases who initiated treatment in late childhood (HR = 2.0, 95% CI = [1.2, 3.4]) or treatment naïve patients (HR = 1.9, 95% CI = [1.1, 3.2]), and higher risk of suffering a fracture (HR = 2.3, 95% CI = [1.4, 3.7] and HR = 2.6, 95% CI = [1.6, 4.2], respectively). Patients with early childhood treatment had slightly decreased respiratory function compared with those with late childhood treatment. Ages at loss of ambulation or scoliosis diagnosis did not differ statistically among treatment groups. We caution that the results from our study are subject to several limitations, as they were based on data abstracted from medical records. Further investigations using improved reporting of disease onset and outcomes are warranted to obtain a more definitive assessment of the association between the timing of corticosteroid treatment and disease severity.

  7. Robenacoxib versus meloxicam for the management of pain and inflammation associated with soft tissue surgery in dogs: a randomized, non-inferiority clinical trial. (United States)

    Gruet, Philippe; Seewald, Wolfgang; King, Jonathan N


    Non-steroidal anti-inflammatory drugs (NSAIDs) are used routinely to control pain and inflammation after surgery in dogs. Robenacoxib is a new NSAID with high selectivity for the cyclo-oxygenase (COX)-2 isoform of COX. The objective of this study was to evaluate the efficacy and tolerability of robenacoxib for the management of peri-operative pain and inflammation associated with soft tissue surgery in dogs. The study was a prospective, randomized, blinded, positive-controlled, non-inferiority, multi-center clinical trial. A total of 174 dogs undergoing major soft tissue surgery were included and randomly allocated in a 2:1 ratio to receive either robenacoxib (n = 118) or the positive control, meloxicam (n = 56). Each dog received an initial dose subcutaneously prior to surgery (robenacoxib 2 mg/kg, meloxicam 0.2 mg/kg), followed by daily oral doses (robenacoxib 1-2 mg/kg, meloxicam 0.1 mg/kg) for 12 days (range 10-14) after surgery. Pain and inflammation were assessed subjectively using the Glasgow Composite Pain Scale (GCPS) by clinicians as the primary end point and additional evaluations by the clinicians and animal owners as secondary endpoints. Both treatments provided similar pain control, with no significant differences between groups for any efficacy variable using non-parametric analyses (Mann-Whitney U test). In no dog was analgesic rescue therapy administered. Non-inferior efficacy of robenacoxib compared to meloxicam was demonstrated statistically for the primary and all secondary endpoints using parametric analysis of variance, although the data were not normally distributed even after log transformation. For the primary endpoint (reciprocal of the modified GCPS score), the relative efficacy of robenacoxib/meloxicam was 1.12 with a 95% confidence interval of 0.97-1.29. A treatment regimen of robenacoxib by subcutaneous injection followed by oral tablets had good tolerability and non-inferior efficacy compared to meloxicam for the

  8. Pain measurement and management in elderly patients : Clinical studies in long term hospital care and after cardiac surgery


    Pesonen, Anne


    The proportion of patients over 75 years of age, receiving all different types of healthcare, is constantly increasing. The elderly undergo surgery and anaesthetic procedures more often than middle-aged patients. Poor pain management in the elderly is still an issue. Although the elderly consumes the greatest proportion of prescribed medicines in Western Europe, most clinical pharmacological studies have been performed in healthy volunteers or middle-aged patients. The aim of this study was t...

  12. Hospital Discharge Information After Elective Total hip or knee Joint Replacement Surgery: A clinical Audit of preferences among general practitioners

    Directory of Open Access Journals (Sweden)

    Andrew M Briggs


    Full Text Available AbstractThe demand for elective joint replacement (EJR surgery for degenerative joint disease continues to rise in Australia, and relative to earlier practices, patients are discharged back to the care of their general practitioner (GP and other community-based providers after a shorter hospital stay and potentially greater post-operative acuity. In order to coordinate safe and effective post-operative care, GPs rely on accurate, timely and clinically-informative information from hospitals when their patients are discharged. The aim of this project was to undertake an audit with GPs regarding their preferences about the components of information provided in discharge summaries for patients undergoing EJR surgery for the hip or knee. GPs in a defined catchment area were invited to respond to an online audit instrument, developed by an interdisciplinary group of clinicians with knowledge of orthopaedic surgery practices. The 15-item instrument required respondents to rank the importance of components of discharge information developed by the clinician working group, using a three-point rating scale. Fifty-three GPs and nine GP registrars responded to the audit invitation (11.0% response rate. All discharge information options were ranked as ‘essential’ by a proportion of respondents, ranging from 14.8–88.5%. Essential information requested by the respondents included early post-operative actions required by the GP, medications prescribed, post-operative complications encountered and noting of any allergies. Non-essential information related to the prosthesis used. The provision of clinical guidelines was largely rated as ‘useful’ information (47.5–56.7%. GPs require a range of clinical information to safely and effectively care for their patients after discharge from hospital for EJR surgery. Implementation of changes to processes used to create discharge summaries will require engagement and collaboration between clinical staff

  15. Design and initial evaluation of a virtual pediatric primary care clinic in Second Life(®). (United States)

    Jane Cook, Mary


    To present an example of an innovative educational strategy using a theoretical framework for the design and evaluation of a virtual world simulation for family nurse practitioner (FNP) students. The example arises from a primary care pediatric clinic developed for FNP students in Second Life(®) to supplement experiences in clinical practice sites. The simulation uses a case-based interactive format. The educational strategy is based on constructivist learning theory and experiential learning principles. Report of initial prototype testing of faculty and FNP students is reported. Virtual-world simulations have the potential to provide a safe environment for students to practice clinical decision making for pediatric patients. However, attention to the context, pedagogy, learner, and the capabilities of the technology is essential to provide a quality educational experience. Preparation of FNP students can include quality educational experiences in a virtual world when guided by a theoretical framework. ©2012 The Author(s) Journal compilation ©2012 American Academy of Nurse Practitioners.

    The past three decades have seen rapid improvements in the diagnosis and treatment of most cancers and the most important contributor has been research. Progress in rare cancers has been slower, not least because of the challenges of undertaking research. The International Rare Cancers Initiative (IRCI) is a partnership which aims to stimulate and facilitate the development of international clinical trials for patients with rare cancers. It is focused on interventional--usually randomized--clinical trials with the clear goal of improving outcomes for patients. The key challenges are organisational and methodological. A multi-disciplinary workshop to review the methods used in ICRI portfolio trials was held in Amsterdam in September 2013. Other as-yet unrealised methods were also discussed. The IRCI trials are each presented to exemplify possible approaches to designing credible trials in rare cancers. Researchers may consider these for use in future trials and understand the choices made for each design. Trials can be designed using a wide array of possibilities. There is no 'one size fits all' solution. In order to make progress in the rare diseases, decisions to change practice will have to be based on less direct evidence from clinical trials than in more common diseases.

  17. Objective Surgical Skill Assessment: An Initial Experience by Means of a Sensory Glove Paving the Way to Open Surgery Simulation? (United States)

    Saggio, Giovanni; Lazzaro, Alessandra; Sbernini, Laura; Carrano, Francesco Maria; Passi, Davide; Corona, Arianna; Panetta, Valentina; Gaspari, Achille L; Di Lorenzo, Nicola


    Simulation and training in surgery are very promising tools for enhancing a surgeon's skill base. Accurate tracking of hand movements can be a strategy for objectively gauging a surgeon's dexterity, although "open" work is much more difficult to evaluate than are laparoscopic tasks. To the authors' knowledge, a system taking into account the movements of each finger joint has never been applied to open surgery simulation. This work intends to make up for this shortcoming and to perform a data analysis of the surgeon's entire gesture. The authors developed a sensory glove to measure flexion/extension of each finger joint and wrist movement. Totally 9 experts and 9 novices performed a basic suturing task and their manual performances were recorded within 2 days of measurements. Intraclass correlation coefficients were calculated to assess the ability of the executors to repeat and reproduce the proposed exercise. Wilcoxon signed-rank tests and Mann-Whitney U-tests were used to determine whether the 2 groups differ significantly in terms of execution time, repeatability, and reproducibility. Finally, a questionnaire was used to gather operators' subjective opinions. The experts needed a similar reduced execution time comparing the 2 recording sessions (p = 0.09), whereas novices spent more time during the first day (p = 0.01). Repeatability did not differ between the 2 days, either for experts (p = 0.26) or for novices (p = 0.86). The 2 groups performed differently in terms of time (p paving the way to a more complex project involving open surgery simulation. Copyright © 2015 Association of Program Directors in Surgery.

  18. Can teenage novel users perform as well as General Surgery residents upon initial exposure to a robotic surgical system simulator? (United States)

    Mehta, A; Patel, S; Robison, W; Senkowski, T; Allen, J; Shaw, E; Senkowski, C


    New techniques in minimally invasive and robotic surgical platforms require staged curricula to insure proficiency. Scant literature exists as to how much simulation should play a role in training those who have skills in advanced surgical technology. The abilities of novel users may help discriminate if surgically experienced users should start at a higher simulation level or if the tasks are too rudimentary. The study's purpose is to explore the ability of General Surgery residents to gain proficiency on the dVSS as compared to novel users. The hypothesis is that Surgery residents will have increased proficiency in skills acquisition as compared to naive users. Six General Surgery residents at a single institution were compared with six teenagers using metrics measured by the dVSS. Participants were given two 1-h sessions to achieve an MScoreTM in the 90th percentile on each of the five simulations. MScoreTM software compiles a variety of metrics including total time, number of attempts, and high score. Statistical analysis was run using Student's t test. Significance was set at p value <0.05. Total time, attempts, and high score were compared between the two groups. The General Surgery residents took significantly less Total Time to complete Pegboard 1 (PB1) (p = 0.043). No significant difference was evident between the two groups in the other four simulations across the same MScoreTM metrics. A focused look at the energy dissection task revealed that overall score might not be discriminant enough. Our findings indicate that prior medical knowledge or surgical experience does not significantly impact one's ability to acquire new skills on the dVSS. It is recommended that residency-training programs begin to include exposure to robotic technology.

  19. The feasibility of solo-surgeon living donor nephrectomy: initial experience using video-assisted minilaparotomy surgery. (United States)

    Lee, Yong Seung; Jeon, Hwang Gyun; Lee, Seung Ryeol; Jeong, Woo Ju; Yang, Seung Choul; Han, Woong Kyu


    Today, many kinds of surgery are being conducted without human assistants. Living donor nephrectomy (LDN) using video-assisted minilaparotomy surgery (VAM) has been performed by solo-surgeon using Unitrac® (Aesculap Surgical Instrument, Germany). We examined the results from VAM-solo-surgeon living donor nephrectomy (SLDN) and conventional VAM-human-assisted living donor nephrectomy (HLDN). Between July 2007 and April 2008, 82 cases of VAM-LDN were performed by two surgeons. From these cases, we randomly assigned 35 cases to undergo solo-surgery (group I) and the other 47 cases to undergo surgery with one human assistant (group II). All VAM-LDN procedures were performed in the same manner. Only the roles of a first assistant were substituted by the Unitrac® in group I. We compared the perioperative and postoperative data, including operative time, estimated blood loss, and hospital stay, between the two groups. We also investigated cases that developed complications. There were no significant differences in the patient demographic data between the two groups (P > 0.05). The mean operative time was 201.9 ± 32.9 min in group I and 202.4 ± 48.3 min in group II (P = 0.954), whereas mean blood loss was 209.7 ± 167.3 ml in group I and 179.6 ± 87.8 ml in group II (P = 0.294). Postoperative hospital stay were 5.4 ± 1.1 days in group I and 5.5 ± 1.6 days in group II (P = 0.813). The incidence of perioperative complications was not significantly different between the two groups. Our study demonstrates that VAM-SLDN can be performed safely, is economically beneficial, and is comparable to VAM-HLDN in terms of postoperative outcomes.

  20. Malnutrition in pregnancy following bariatric surgery: three clinical cases of fetal neural defects. (United States)

    Pelizzo, Gloria; Calcaterra, Valeria; Fusillo, Mario; Nakib, Ghassan; Ierullo, Antonio Maria; Alfei, Alessandro; Spinillo, Arsenio; Stronati, Mauro; Cena, Hellas


    Bariatric surgery results in decreased food intake and a variable degree of malabsorption. Without adequate supplementation, the most common complications of this surgery are nutritional disorders. Pregnancy following surgery for obesity is a particular condition requiring strict monitoring of nutrient intake necessary for fetal development and a favourable neonatal prognosis. Malnutrition in pregnancy and congenital neural malformations are reported in three women who had previously undergone bariatric surgery (1, 5 and 18 years before pregnancy, respectively). Two patients underwent the Roux en Y bypass and one bilio-pancreatic diversion with gastroplasty. None of the three received pre-conceptional nutritional counselling. Patients 1 and 2 did not undergo postoperative nutritional surveillance; nutrient supplementation was started at 22 and 20 weeks gestation, respectively. In patient 3, supplementation was stopped at six weeks gestation. Newborns 1 and 2 presented with dorsal myelomeningocele and ventricular dilation. Both underwent surgery and a ventriculo-peritoneal shunt was inserted in the first month of life. Newborn 3 had microcephaly, bilateral microphthalmia and sensorineural deafness. Diet and nutritional status, before and during pregnancy, play an important role in the early processes of fetal development and neonatal outcome. Women of childbearing age who have had bariatric surgery, should be encouraged to follow a well-balanced diet as part of a weight management strategy. They should be advised to take recommended maternal supplements.

  1. Randomized clinical trial examining the effect of music therapy in stress response to day surgery. (United States)

    Leardi, S; Pietroletti, R; Angeloni, G; Necozione, S; Ranalletta, G; Del Gusto, B


    Music therapy could reduce stress and the stress response. The aim of this study was to investigate the role of music therapy in alleviating stress during day surgery. Sixty patients undergoing day surgery were randomized to one of three groups, each containing 20 patients. Before and during surgery, patients in group 1 listened to new age music and those in group 2 listened to a choice of music from one of four styles. Patients in group 3 (control group) heard the normal sounds of the operating theatre. Plasma levels of cortisol and subpopulations of lymphocytes were evaluated before, during and after operation. Plasma cortisol levels decreased during operation in both groups of patients who listened to music, but increased in the control group. Postoperative cortisol levels were significantly higher in group 1 than in group 2 (mean(s.d.) 14.21(6.96) versus 8.63(2.72) ng/dl respectively; P < 0.050). Levels of natural killer lymphocytes decreased during surgery in groups 1 and 2, but increased in controls. Intraoperative levels of natural killer cells were significantly lower in group 1 than in group 3 (mean(s.d.) 212.2(89.3) versus 329.1(167.8) cells/microl; P < 0.050). Perioperative music therapy changed the neurohormonal and immune stress response to day surgery, especially when the type of music was selected by the patient.

    The objective of this study was to examine the post-operative complications of surgical procedures in oral or pharyngeal carcinoma by analyzing and comparing between patients who underwent salvage surgery after chemoradiation and radiation. A retrospective review was performed of 18 patients who underwent salvage surgery and reconstruction after concurrent chemoradiotherapy (CCRT group), and another 41 patients who underwent salvage surgery and reconstruction after radiation therapy (RT group). No perioperative deaths or life threatening systemic complications occurred, and all flaps survived completely in both groups. Surgical site infection (SSI) occurred in five patients (12.2%) in the RT group and seven patients (38%) in the CCRT group. SSI other than donor site infection occurred in four patients (9%) in the RT group and four patients (22%) in the CCRT group. The rate of SSI excluding donor site infection did not differ significantly between patients who underwent salvage surgery after CCRT and RT. The rate of donor site infection was higher in the CCRT group than in the RT group (p=0.04). This study showed that salvage surgery after CCRT or RT can be performed safely, without significant morbidity or mortality. However, patients who received CCRT are at risk for major complications caused by minor troubles, and thus reconstruction after salvage surgery should be performed with sufficient care. (author)

  3. Treatment of degenerative cervical spondylosis with radiculopathy. Clinical practice guidelines endorsed by The Polish Society of Spinal Surgery. (United States)

    Latka, Dariusz; Miekisiak, Grzegorz; Jarmuzek, Pawel; Lachowski, Marcin; Kaczmarczyk, Jacek


    Degenerative cervical spondylosis (DCS) with radiculopathy is the most common indication for cervical spine surgery despite favorable natural history. Advances in spinal surgery in conjunction with difficulties in measuring the outcomes caused the paucity of uniform guidelines for the surgical management of DCS. The aim of this paper is to develop guidelines for surgical treatment of DCS. For this purpose the available up-to-date literature relevant on the topic was critically reviewed. Six questions regarding most important clinical questions encountered in the daily practice were formulated. They were answered based upon the systematic literature review, thus creating a set of guidelines. The guidelines were categorized into four tiers based on the level of evidence (I-III and X). They were designed to assist in the selection of optimal and effective treatment leading to the most successful outcome. The evidence based medicine (EBM) is increasingly popular among spinal surgeons. It allows making unbiased, optimal clinical decisions, eliminating the detrimental effect of numerous conflicts of interest. The key role of opinion leaders as well as professional societies is to provide guidelines for practice based on available clinical evidence. The present work contains a set of guidelines for surgical treatment of DCS officially endorsed by the Polish Spine Surgery Society. Copyright © 2015 Polish Neurological Society.

    This study aimed to evaluate the diagnostic yield of preoperative computed tomography (CT) imaging and the validity of surgical intervention based on the clinical decision to perform surgery for lung cancer or suspected lung cancer. We retrospectively evaluated 1755 patients who had undergone pulmonary resection for lung cancer or suspected lung cancer. CT scans were performed on all patients. Surgical intervention to diagnose and treat was based on a medical staff conference evaluation for the suspected lung cancer patients who were pathologically undiagnosed. We evaluated the relation between resected specimens and preoperative CT imaging in detail. A total of 1289 patients were diagnosed with lung cancer by preoperative pathology examination; another 466 were not pathologically diagnosed preoperatively. Among the 1289 patients preoperatively diagnosed with lung cancer, the diagnoses were confirmed postoperatively in 1282. Among the 466 patients preoperatively undiagnosed, 435 were definitively diagnosed with lung cancer, and there were 383 p-stage I disease patients. There were 38 noncancerous patients who underwent surgery with a diagnosis of confirmed or suspected lung cancer. Among the 1755 patients who underwent surgery, 1717 were pathologically confirmed with lung cancer, and the diagnostic yield of preoperative CT imaging was 97.8%. Among the 466 patients who were preoperatively undiagnosed, 435 were compatible with the predicted findings of lung cancer. Diagnostic yields of preoperative CT imaging based on clinical evaluation are sufficiently reliable. Diagnostic surgical intervention was acceptable when the clinical probability of malignancy was high and the malignancy was pathologically undiagnosed. (author)

  5. Gamma Imaging-Guided Minimally Invasive Breast Biopsy: Initial Clinical Experience. (United States)

    Brem, Rachel F; Mehta, Anita K; Rapelyea, Jocelyn A; Akin, Esma A; Bazoberry, Adriana M; Velasco, Christel D


    The purpose of this study was to evaluate our initial experience with gamma imaging-guided vacuum-assisted breast biopsy in women with abnormal findings. A retrospective review of patients undergoing breast-specific gamma imaging (BSGI), also known as molecular breast imaging (MBI), between April 2011 and October 2015 found 117 nonpalpable mammographically and sonographically occult lesions for which gamma imaging-guided biopsies were recommended. Biopsy was performed with a 9-gauge vacuum-assisted device with subsequent placement of a titanium biopsy site marker. Medical records and pathologic findings were evaluated. Of the 117 biopsies recommended, 104 were successful and 13 were canceled. Of the 104 performed biopsies, 32 (30.8%) had abnormal pathologic findings. Of those 32 biopsies, nine (28.1%) found invasive cancers, six (18.8%) found ductal carcinoma in situ (DCIS), and 17 (53.1%) found high-risk lesions. Of the 17 high-risk lesions, there were three (17.6%) lobular carcinomas in situ, five (29.4%) atypical ductal hyperplasias, two (11.8%) atypical lobular hyperplasias, one (5.9%) flat epithelial atypia, and six (35.3%) papillomas. Two cases of atypical ductal hyperplasia were upgraded to DCIS at surgery. The overall cancer detection rate for gamma imaging-guided biopsy was 16.3%. In this study, gamma imaging-guided biopsy had a positive predictive value of total successful biopsies of 16.3% for cancer and 30.8% for cancer and high-risk lesions. Gamma imaging-guided biopsy is a viable approach to sampling BSGI-MBI-detected lesions without sonographic or mammographic correlate. Our results compare favorably to those reported for MRI-guided biopsy.

  6. Clinical outcomes after injection of a compounded pharmaceutical for prophylaxis after cataract surgery: a large-scale review. (United States)

    Tyson, Sydney L; Bailey, Robert; Roman, Janika S; Zhan, Tingting; Hark, Lisa A; Haller, Julia A


    To evaluate relevant clinical outcomes following a transzonular intravitreal injection of a compounded triamcinolone-moxifloxacin-vancomycin (TMV) formulation for postoperative prophylaxis after cataract surgery in a retrospective review of medical records from a private practice, single-specialty ambulatory center in New Jersey, USA. The analysis included 1541 cases from 922 patients who underwent cataract surgery with an intravitreal injection of TMV from November 2013 to December 2014. Cataract surgery was performed by a standard clear corneal phacoemulsification technique. Transzonular injection was used to deliver TMV directly into the anterior vitreous after implantation of an intraocular lens. There were no major intraoperative complications associated with the transzonular injection technique. There were no cases of postoperative endophthalmitis. Nearly 92% of cases (n = 1413/1541) did not require supplemental medication after surgery. The rate of breakthrough inflammation at Days 14-21 was 9.2% (n = 132/1429). The rate of visually significant postoperative cystoid macular edema was 2.0% (n = 28/1429). The rate of clinically significant postoperative intraocular pressure increase was low: 0.9% (n = 13/1425) of cases had an at least 10 mmHg increase at Days 14-21 or 90. Four of these cases had intraocular pressure at least 30 mmHg. The rates of infection and inflammation reported in this retrospective review of a transzonular injection of TMV for prophylaxis after cataract surgery appear similar to reported rates with alternative prophylactic therapies such as topical drops. The transzonular injection of TMV may have advantages in terms of patient compliance.

  7. Reference markers in computer aided orthopaedic surgery: rotational stability testings and clinical implications. (United States)

    Kendoff, Daniel; Gardner, Michael J; Krettek, Christian; Hüfner, Tobias; Citak, Musa


    Navigation procedures rely on the stability of the reference arrays (RA) fixed to the bony anatomy. The risk of inadvertent collision and unnoticed movements of the RA may occur, and limb movements might also provocate collisions. Consequently, relevant measurements failures during the navigated procedure might occur and reduce the overall precision of the system. The magnitude of torque to destabilize an RA from its bony-fixation is unknown. The purpose of this study was to determine the ability of standard RA's to resist applied torque. A digital torque application device was developed to allow for precise torque application to the RA system at four cadavers. Clockwise, gradually increasing rotational force was applied to the RA in 1, 2, or 3 Nm, held for 1 s and released, repeated in 10 cycles. One pin fixation systems with 4.0 Schanz pins were used. A second RA was fixed 20 cm proximal to the tested RA. A navigation system was used to measure the relative positions of both RA's during torque application. The rotational differences at torque application were calculated and statistically evaluated. Results revealed averaged 1.0 degrees rotation [range (r), 1.0-1.1 degrees ] with first cycle of 1 Nm torque, the last cycle averaged 1.0 degrees (r, 1.0-1.1 degrees ) with no significant differences in rotation between any of the cycles (p > 0.5). Torque of 2 Nm resulted in 1.8 degrees rotation (r, 1.5-1.8 degrees ) with no significant increases between first and second cycle (p = 0.56), second and third trials (p = 0.35) while fourth cycle averaged 2.0 degrees , with significant increase (p = 0.011). All subsequent cycles resulted in significant increases. Torque of 3 Nm produced 2.9 degrees of rotation for initial cycle (r,2.5-3.3 degrees ), with significant increases with each cycle (p or =2 Nm may cause loosening of the RA, thus may lose its original position relative to the bone. Surgeons using computer aided surgery systems should be aware of possible

  8. Medication use among pediatric patients with chronic musculoskeletal pain syndromes at initial pain clinic evaluation. (United States)

    W Guite, Jessica; Sherry, David D; Jarvis, Esther W; O Lewen, Margaret; Khan, Sarosh; Wickham Kraemer, Francis


    To characterize medication use by adolescents with chronic musculoskeletal pain syndromes before an initial multidisciplinary clinic visit. A cross-sectional sample of 120 adolescents and parents reported on standardized assessment measures, with medication use data extracted from the medical chart and categorized. On average, 3.2 medications were reported; 70% used more than one pain-specific medication including opioids (17%), nonopioids (31%), psychotropics/neuropathics (45%) and other medications (13%). Adolescents with complex regional pain syndrome consistently reported greatest use of opioid, psychotropic/neuropathic and other pain medications. A regression model explained 17% of the variance in pain medication use. Nonpain medication use and disability contributed unique variance - pain duration and intensity did not. Greater attention to factors contributing to prescriptive practices, medication use and long-term outcomes is warranted.
