    The aim of this case report was to describe the surgical sequence of crown lengthening to apically reposition the dentogingival complex, in addition to an esthetic restorative procedure. Many different causes can be responsible for short clinical crown. In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length. According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment.

    Although electronic health record (EHR) systems have potential benefits, such as improved safety and quality of care, most ophthalmology practices in the United States have not adopted these systems. Concerns persist regarding potential negative impacts on clinical workflow. In particular, the impact of EHR operating room (OR) management systems on clinical efficiency in the ophthalmic surgery setting is unknown. To determine the impact of an EHR OR management system on intraoperative nursing documentation time, surgical volume, and staffing requirements. For documentation time and circulating nurses per procedure, a prospective cohort design was used between January 10, 2012, and January 10, 2013. For surgical volume and overall staffing requirements, a case series design was used between January 29, 2011, and January 28, 2013. This study involved ophthalmic OR nurses (n = 13) and surgeons (n = 25) at an academic medical center. Electronic health record OR management system implementation. (1) Documentation time (percentage of operating time documenting [POTD], absolute documentation time in minutes), (2) surgical volume (procedures/time), and (3) staffing requirements (full-time equivalents, circulating nurses/procedure). Outcomes were measured during a baseline period when paper documentation was used and during the early (first 3 months) and late (4-12 months) periods after EHR implementation. There was a worsening in total POTD in the early EHR period (83%) vs paper baseline (41%) (P system implementation was associated with worsening of intraoperative nursing documentation time especially in shorter procedures. However, it is possible to implement an EHR OR management system without serious negative impacts on surgical volume and staffing requirements.

    Full Text Available The Sushruta Samhita is an Ayurvedic text, by the legendary Sushruta, foundational to Ayurvedic medicine (Indian traditional medicine, with innovative chapters mainly on surgery. There is a general impression that Sushruta Samhita is only an ancient Indian Ayurvedic text book of surgery. Sushruta Samhita contains 184 chapters and description of 1120 illnesses, 700 medicinal plants, a detailed study on anatomy, 64 preparations from mineral sources and 57 preparations based on animal sources. It still retains the land mark position in the field of surgical texts. In addition to his worldwide known work of historical significance on plastic surgery, he also made similar unique contributions on numerous aspects of medicine, such as fracture and dislocations, urinary stones, skin diseases including leprosy, Pancha Karma (Purification procedures, toxicology, pediatrics, eye diseases, psychiatry, obstetrics and gynaecology, etc. A very limited conceptual work has been performed on the selected chapters of Sushruta Samhita. Therefore a review conceptual study has been carried out on the various surgical concepts of Sushruta Samhita. Outcome of this study shows, Sushruta Samhita is written in the aphorism form and the techniques described in it are eminently in line with technical abilities of the times. It is need of the hour to explore the hidden truth by decoding the versions of the texts.

    Minimally invasive therapy (MIT) is one of the most important trends in modern medicine. It includes a wide range of therapies in videoscopic surgery and interventional radiology and is performed through small incisions. It reduces hospital stay-time by allowing faster recovery and offers substantially improved cost-effectiveness for the hospital and the society. However, the introduction of MIT has also led to new problems. The manipulation of structures within the body through small incisions reduces dexterity and tactile feedback. It requires a different approach than conventional surgical procedures, since eye-hand co-ordination is not based on direct vision, but more predominantly on image guidance via endoscopes or radiological imaging modalities. ARIS*ER is a multidisciplinary consortium developing a new generation of decision support tools for MIT by augmenting visual and sensorial feedback. We will present tools based on novel concepts in visualization, robotics and haptics providing tailored solutions for a range of clinical applications. Examples from radio-frequency ablation of liver-tumors, laparoscopic liver surgery and minimally invasive cardiac surgery will be presented. Demonstrators were developed with the aim to provide a seamless workflow for the clinical user conducting image-guided therapy.

    Twenty cases of craniopharyngiomas treated surgically between 1972 and 1979 have been studed neuro-ophthalmologically. The visual fields demonstrated asymetrical bitemporal hemianopsia, occasionally homonymous hemianopsia and central scotomas. The visual function was followed up for a period of one to 8 years after the operation. Improvement and retention of the visual function were observed in 88% of cases with subtotal resection and irradiation, 45% of cases with partial resection and irradiation, and 0% of totally resected cases. Histopathologically, the dense adhesion and tumor invasion in the optic chiasm were observed in autopsy cases. From the viewpoint of operative results and autopsy findings, the subtotal excision with irradiation is advocated for the treatment of craniopharyngiomas, particularly in the adult cases.

    Significant advances in veterinary diagnostic and surgical techniques have been made over the past several decades. Many of these advances, however, have not reached the field of marine mammal medicine. A number of limitations exist: risks of anesthesia, anatomical challenges, difficulties with wound closure, environmental constraints, equipment limitations, and perceived risks. Despite these limitations, surgical treatments have been successfully utilized in marine mammals. While surgery is performed in pinnipeds more frequently than in cetaceans, studies conducted in the 1960s and 1970s on dolphin sleep and hearing demonstrated that general anesthesia can be successfully induced in cetaceans. Since this pioneering work, a small number of successful surgeries have been performed in dolphins under both general anesthesia and heavy sedation. While these surgical procedures in pinnipeds and cetaceans have typically been limited to wound management, dentistry, ophthalmic procedures, fracture repair, and superficial biopsy, a number of abdominal surgeries have also been performed. Recently there have been pioneering successes in the application of minimally invasive surgery in marine mammals. Many of the anatomical challenges that almost prohibit traditional laparotomies in cetacean species and present challenges in pinnipeds can be overcome through the use of laparoscopic techniques. Due to the limited number of pinnipeds and cetaceans in captivity and, thus, the limited case load for veterinarians serving marine mammal species, it is vital for knowledge of surgical procedures to be shared among those in the field. This paper reviews case reports of surgical procedures, both traditional and laparoscopic, in pinnipeds and cetaceans. Limitations to performing surgical procedures in marine mammals are discussed and surgical case reports analyzed in an effort to determine challenges that must be overcome in order to make surgery a more feasible diagnostic and treatment

    In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

    In clinical practice performing any surgical procedure is inconsistent because all surgical procedures carry definitely some degree of risk. Worldwide every year millions of patients go under knife, but many of them are enduring great pain and shelling out thousands and dollars for surgeries they don't really need. This review work was planned with an intention to focus attention towards it with reporting cited evidences of unnecessary surgical operations and discuss ethical issues concern with it. In present review the references search included standard citations Google scholar, MEDLINE and PUBMED. We also used Google search engine for screening various news concern with highlighting this topic in community and online media. For articles we go through more than 60 articles from worldwide and 12 news media views from Google search in last one year. We used following quotes for their search-unnecessary surgeries, second opinion, ethical issues in unnecessary surgeries. Geographical variations were also kept in view. Our intension was highlighting ethical issues concern with unnecessary surgical operations. Henceforth we excluded such work that does not concern with ethical issues. Unnecessary surgery is that which is medically unjustifiable when the risks and costs are more than the likely therapeutic benefits or relief to the patient based on the patient's lifestyle requirements. To avoid or minimize such interventions basic seeding of ethics in curriculum and strict laws will definitely helpful in clinical practice. In conclusion, our aim was to highlight this major issue and underline need of competency based medical bioethics education in Indian scenario.

    2016-09-01

    A reliable means for measuring temperatures generated during surgical procedures is needed to recommend best practices for inserting fixation devices and minimizing the risk of osteonecrosis. Twenty four screw tests for three surgical procedures were conducted using the four thermocouples in the bone and one thermocouple in the screw. The maximum temperature rise recorded from the thermocouple in the screw (92.7±8.9°C, 158.7±20.9°C, 204.4±35.2°C) was consistently higher than the average temperature rise recorded in the bone (31.8±9.3°C, 44.9±12.4°C, 77.3±12.7°C). The same overall trend between the temperatures that resulted from three screw insertion procedures was recorded with significant statistical analyses using either the thermocouple in the screw or the average of several in-bone thermocouples. Placing a single thermocouple in the bone was determined to have limitations in accurately comparing temperatures from different external fixation screw insertion procedures. Using the preferred measurement techniques, a standard screw with a predrilled hole was found to have the lowest maximum temperatures for the shortest duration compared to the other two insertion procedures. Future studies evaluating bone temperature increase need to use reliable temperature measurements for recommending best practices to surgeons.

    The inability of some children to tolerate detailed eye examinations often necessitates general anaesthesia (GA). The objective was to assess the incremental cost effectiveness of paediatric eye examinations carried out in an outpatient sedation unit compared with GA. An episode of care cost-effectiveness analysis was conducted from a societal perspective. Model inputs were based on a retrospective cross-over cohort of Canadian children aged 68 successful procedures per child. The result was robust to varying the cost assumptions. Cross-over designs offer a powerful way to assess costs and effectiveness of two interventions because patients serve as their own control. This study demonstrated significant savings when ophthalmological exams were carried out in a hospital outpatient clinic, although with slightly fewer procedures completed.

    2015-09-01

    To ensure optimal results, we must do our utmost to achieve targets based on order, symmetry and precision, our ultimate aim being to strive towards the desired harmony, planned contrast and exact proportions. Orthodontic-surgical treatments require specific finishing procedures, which most often call for multidisciplinary, or even transdisciplinary, collaboration. Finishing will involve the dental arches just as much as the orofacial environment. Above all, treatment of this kind demands a highly targeted approach in combination with well-defined and perfectly executed techniques. To finish a case satisfactorily, reasonable targets should be aimed for to ensure they are achieved. One must be ambitious and yet wise. A tight alliance of surgeon and orthodontist will nurture convincing and achievable projects and good, lifelong outcomes. Following the consolidation phase, roughly 4 to 6 weeks post-surgery, we can initiate the final orthodontic treatment, which, in effect, constitutes a mini-treatment in its own right. "Details make perfection, but perfection is not a detail" (Leonardo Da Vinci). "A lucid mind is the ante-chamber of intelligence" (Léo Ferré). In the order of life, every form of unity is always unique, and if each of us is unique, it is because everyone else is too. Ambition, wisdom, lucidity and efficiency will guarantee a successful result, the successful result. We must not be mere observers of our treatments, but the architect, project manager and site foreman at one and the same time. One could talk ad infinitum about finishing orthodontic-surgical cases because everything else leads up to the case-finishing and even the fullest description could never be exhaustive.

    To design and implement a teaching skills curriculum that addressed the needs of an ophthalmology residency training program, to assess the effect of the curriculum, and to present important lessons learned. A teaching skills curriculum was designed for the Harvard Medical School (HMS) Residency Training Program in Ophthalmology. Results of a needs assessment survey were used to guide curriculum objectives. Overall, 3 teaching workshops were conducted between October 2012 and March 2013 that addressed areas of need, including procedural teaching. A postcurriculum survey was used to assess the effect of the curriculum. Massachusetts Eye and Ear Infirmary, a tertiary care institution in Boston, MA. Overall, 24 residents in the HMS Residency Training Program in Ophthalmology were included. The needs assessment survey demonstrated that although most residents anticipated that teaching would be important in their future career, only one-third had prior formal training in teaching. All residents reported they found the teaching workshops to be either very or extremely useful. All residents reported they would like further training in teaching, with most residents requesting additional training in best procedural teaching practices for future sessions. The pilot year of the resident-as-teacher curriculum for the HMS Residency Training Program in Ophthalmology demonstrated a need for this curriculum and was perceived as beneficial by the residents, who reported increased comfort in their teaching skills after attending the workshops.

    2010-01-01

    The historical pathway to current surgical endodontic procedures and their applications has been tortuous and tumultuous. Influenced heavily in their development by the European sector, these surgical procedures faced many challenges over the decades. Fortunately for today's practitioners, influential members of the oral surgery community, and a few staunch believers in retaining devitalized teeth, persisted in their investigation of and search for improved procedures that had predictable outcomes. Many so-called "revolutionary" or newer techniques practiced today are but a re-emergence of surgical concepts that were lost in the archives of time. With the advent of evidence-based endodontics, these procedures are now supported extensively by science and by the integration of science into materials usage, technique applications and outcomes research. However, in many respects, this story is just beginning, as the "roots" of surgical endodontics are explored.

    2015-01-01

    Pneumatic tourniquet has been frequently utilized in various surgical specialties to facilitate surgical procedures on the extremities. However, its use for surgical procedures of hemodialysis access has been limited to some surgeons in the United States and often confined to the hospital settings under general anesthesia or regional nerve block. We have successfully employed a pneumatic tourniquet system for surgical procedures of hemodialysis access under conscious sedation and local anesthesia in an outpatient setting. Because prolonged tourniquet inflation is associated with ischemic pain and other potential complications, we have limited the continuous inflation time to pneumatic tourniquet use is well tolerated under conscious sedation and not associated with significant adverse events. These and other reported data suggest that pneumatic tourniquet can reduce procedure time, minimize required dissection, reduce vascular trauma by eliminating vascular clamps and potentially improve the outcomes of surgical procedures of hemodialysis access. These advantages may be translated into cost savings for hemodialysis access care. This review discusses practical issues of pneumatic tourniquet use and its applications in surgical procedures of hemodialysis access. © 2014 Wiley Periodicals, Inc.

    Surgical site infections have been categorized by the Centers for Medicare and Medicaid Services as "never events". The incidence of surgical site infection following laparoscopic urological surgery and its risk factors are poorly defined. We evaluated surgical site infection following urological laparoscopic surgery and identified possible factors that may influence occurrence. Patients who underwent transperitoneal laparoscopic procedures during a 4-year period by a single laparoscopic surgeon were retrospectively reviewed. Surgical site infections were identified postoperatively and defined using the Centers for Disease Control criteria. Clinical parameters, comorbidities, smoking history, preoperative urinalysis and culture results as well as operative data were analyzed. Nonparametric testing using the Mann-Whitney U test, multivariable logistic regression and Spearman's rank correlation coefficient were used for data analysis. In 556 patients undergoing urological laparoscopic procedures 14 surgical site infections (2.5%) were identified at mean postoperative day 21.5. Of the 14 surgical site infections 10 (71.4%) were located at a specimen extraction site. Operative time, procedure type and increasing body mass index were significantly associated with the occurrence of surgical site infections (p = 0.007, p = 0.019, p = 0.038, respectively), whereas history of diabetes mellitus (p = 0.071) and intraoperative transfusion (p = 0.053) were found to trend toward significance. Age, gender, positive urine culture, steroid use, procedure type and smoking history were not significantly associated with surgical site infection. Body mass index and operative time remained significant predictors of surgical site infection on multivariate logistic regression analysis.

    Full Text Available Bariatric surgery is now accepted as a safe and effective procedure for morbid obesity. The frequency of bariatric procedures is increasing with the adoption of the laparoscopic approach. The general surgeons will be facing many more of such patients presenting with common general surgical problems. Many of the general surgeons, faced with such situations, may not be aware of the changes in the gastrointestinal anatomy following bariatric procedures and management of these clinical situations will therefore present diagnostic and therapeutic challenges. We hereby present a review of management of few common general surgical problems in patients with a history of bariatric surgery.

    2014-07-01

    Ophthalmology has been an early adopter of personalized medicine. Drawing on genomic advances to improve molecular diagnosis, such as next-generation sequencing, and basic and translational research to develop novel therapies, application of genetic technologies in ophthalmology now heralds development of gene replacement therapies for some inherited monogenic eye diseases. It also promises to alter prediction, diagnosis and management of the complex disease age-related macular degeneration. Personalized ophthalmology is underpinned by an understanding of the molecular basis of eye disease. Two important areas of focus are required for adoption of personalized approaches: disease stratification and individualization. Disease stratification relies on phenotypic and genetic assessment leading to molecular diagnosis; individualization encompasses all aspects of patient management from optimized genetic counseling and conventional therapies to trials of novel DNA-based therapies. This review discusses the clinical implications of these twin strategies. Advantages and implications of genetic testing for patients with inherited eye diseases, choice of molecular diagnostic modality, drivers for adoption of personalized ophthalmology, service planning implications, ethical considerations and future challenges are considered. Indeed, whilst many difficulties remain, personalized ophthalmology truly has the potential to revolutionize the specialty.

    Although medical treatment and endoscopic interven-tions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Al-though pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complica-tion and pancreatic exocrine or/and endocrine dysfunc-tion rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to ana-lyze its outcome. Because of its hybrid nature, combin-ing both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical proce-dure performed for chronic pancreatitis.

    It has become widely accepted that whenever animals are used in scientific procedures, the 3Rs principle of replacement, reduction and refinement described by William Russell and Rex Burch should be adhered to. Animals should be replaced with non-sentient alternatives if possible, the number of animals used should be reduced and experimental procedures should be refined to minimise pain, suffering and distress. Administration of analgesic agents to animals undergoing surgical procedures is a refinement used to alleviate pain. In this study, a structured literature review was carried out to examine current trends in analgesic administration to rabbits undergoing experimental surgical procedures. 128 papers from 51 peer-reviewed journals were selected for inclusion in this review.

    Current surgical treatment of prostate cancer is typically accomplished by either open radical prostatectomy (ORP) or robotic-assisted laparoscopic radical prostatectomy (RALRP).Intra-operative procedural differences between the two surgical approaches may alter the molecular composition of resected surgical specimens,which are indispensable for molecular analysis and biomarker evaluation.The objective of this study is to investigate the effect of different surgical procedures on RNA quality and genome-wide expression signature.RNA integrity number (RIN) values were compared between total RNA samples extracted from consecutive LRP (n=11 ) and ORP (n=24) prostate specimens.Expression profiling was performed using the Agilent human whole-genome expression microarrays.Expression differences by surgical type were analyzed by Volcano plot analysis and gene ontology analysis.Quantitative reverse transcription (RT)-PCR was used for expression validation in an independent set of LRP (n=8) and ORP (n=8) samples.The LRP procedure did not compromise RNA integrity.Differential gene expression by surgery types was limited to a small subset of genes,the number of which was smaller than that expected by chance.Unexpectedly,this small subset of differentially expressed genes was enriched for those encoding transcription factors,oxygen transporters and other previously reported surgery-induced stress-response genes,and demonstrated unidirectional reduction in LRP specimens in comparison to ORP specimens.The effect of the LRP procedure on RNA quality and genome-wide transcript levels is negligible,supporting the suitability of LRP surgical specimens for routine molecular analysis.Blunted in vivo stress response in LRP specimens,likely mediated by CO2 insufflation but not by longer ischemia time,is manifested in the reduced expression of stress-response genes in these specimens.

    Septic arthritis of the knee is encountered on a regular basis by orthopedists and nonorthopedists. No established therapeutic algorithm exists for septic arthritis of the knee, and there is much variability in management. This study assessed the number of surgical procedures, arthroscopic or open, required to eradicate infection. The study was a retrospective analysis of 79 patients who were treated for septic knee arthritis from 1995 to 2011. Patients who were included in the study had native septic knee arthritis that had resolved with treatment consisting of irrigation and debridement, either open or arthroscopic. Logistic regression analysis was used to explore the relation between the interval between onset of symptoms and index surgery and the use of arthroscopy and the need for multiple procedures. Fifty-two patients met the inclusion criteria, and 53% were male, with average follow-up of 7.2 years (range, 1-16.2 years). Arthroscopic irrigation and debridement was performed in 70% of cases. On average, successful treatment required 1.3 procedures (SD, 0.6; range, 1-4 procedures). A significant relation (P=.012) was found between time from presentation to surgery and the need for multiple procedures. With arthroscopic irrigation and debridement, most patients with septic knee arthritis require only 1 surgical procedure to eradicate infection. The need for multiple procedures increases with time from onset of symptoms to surgery.

    An assessment of the rate of surgical site infections associated with elective paediatric otolaryngology surgical procedures. Prospective data was collected for a 3-week period for all children undergoing surgery where either mucosa or skin was breached. The parents of the children were requested to complete a questionnaire at 30 days after the operation. Data was collected on 80 consecutive cases. The majority of cases were admitted on the day of the procedure. The procedures included adenotonsillectomy (24), grommets (12), cochlear implantation (6), bone-anchored hearing aid (2), submandibular gland excision (1), branchial sinus excision (1), cystic hygroma excision (3), nasal glioma excision (1), microlaryngobronchoscopy (13), tracheostomy (3) and other procedures (14). Nearly half the cases had more than one operation done at the same time. 26/80 (32.5%) patients had a temporary or permanent implant inserted at the time of operation (grommet, bone-anchored hearing aid, cochlear implant). 25/80 (31%) operative fields were classed as clean and 55/80 (68.7%) as clean contaminated operations. The duration of the operation varied from 6 min to 142 min. Hospital antibiotic protocol was adhered to in 69/80 (86.3%) cases but not in 11/80 cases. In our series, 3/80 (3.7%) patients had an infection in the postoperative period. Surgical site infections do occur at an appreciable rate in paediatric otolaryngology. With the potential for serious consequences, reduction in the risk of surgical site infections is important. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available As surgeons, we are morally committed to respecting the right of self-determination of patients, thus an informed consent is necessary before any operative intervention. Many neurosurgical patients are incapable of giving consent because of impaired consciousness. Moreover, neurosurgical procedures involve high risks and often are time sensitive; therefore obtaining consent is a challenging job. Patients and their family members need immense courage, understanding, and trust before giving consent for a surgical procedure to a doctor. Lawsuits against doctors are on the rise and it is important to understand "what is consent?" in legal parlance.

  3. A novel surgical procedure for bridging of massive bone defects

    2005-02-01

    Full Text Available Abstract Background Bony defects arising from tumor resection or debridement after infection, non-union or trauma present a challenging problem to orthopedic surgeons, as well as patients due to compliance issues. Current treatment options are time intensive, require more than one operation and are associated with high rate of complications. For this reason, we developed a new surgical procedure to bridge a massive long bone defect. Methods To bridge the gap, an in situ periosteal sleeve is elevated circumferentially off of healthy diaphyseal bone adjacent to the bone defect. Then, the adjacent bone is osteotomized and the transport segment is moved along an intramedullary nail, out of the periosteal sleeve and into the original diaphyseal defect, where it is docked. Vascularity is maintained through retention of the soft tissue attachments to the in situ periosteal sleeve. In addition, periosteal osteogenesis can be augmented through utilization of cancellous bone graft or in situ cortical bone adherent to the periosteal sleeve. Results The proposed procedure is novel in that it exploits the osteogenic potential of the periosteum by replacing the defect arising from resection of tissue out of a pathological area with a defect in a healthy area of tissue, through transport of the adjacent bone segment. Furthermore, the proposed procedure has several advantages over the current standard of care including ease of implementation, rapid patient mobilization, and no need for specialized implants (intramedullary nails are standard inventory for surgical oncology and trauma departments or costly orthobiologics. Conclusions The proposed procedure offers a viable and potentially preferable alternative to the current standard treatment modalities, particularly in areas of the world where few surgeons are trained for procedures such as distraction osteogenesis (e.g. the Ilizarov procedure as well as areas of the world where surgeons have little access to

    The trend toward transoral access, be it for pathology or facial cosmetic surgery, has become increasingly popular over the last two decades with facial incisions being used more and more sporadically than otherwise. Transoral access because of its inherent limitations, retraction of the oral and perioral tissues without inducing physical or thermal injury makes it a daunting task for the operating surgeon. The use of conventional retractors in conjunction with surgical instruments can lead to inadvertent injury to the perioral tissues resulting in untoward postoperative sequelae leading to patient discomfort and delayed recovery. This article elucidates the versatility of a simple photographic retractor (spandex) as a useful adjunctive tool in the retraction and protection of the perioral tissues for almost all transoral surgical procedures.

    Full Text Available Background/Aim. Primary coxarthrosis occurs often in older population. There is possibility of implanting both endoprothesis simultaneously in bilateral coxarthrosis which decreases hospitalization and reduces the expenses and possibility of complication that can occur during general anesthesia. The most serious indications for bilateral total hip arthroplasty in one procedure are younger patients with serious bilateral osteoarthrosis of the hips, without added diseases. Absolute contraindication is found in patients with persistent ductus arteriosus and septal defect. The aim of this study was to point out the possibility and advantages of a single-staged bilateral hip arthroplasty and introducing it in our orthopedic practice. Methods. The procedure was accomplished in 19 patients. The standard total hip arthroplasty surgical technique was performed, followed by the usual antibiotic and anticoagulant therapy. Results. Only one complication - acetabular part instability we recorded, followed by luxation that was surgically managed. Conclusion. This procedure can be performed routinely in selected population and should be reserved for major medical centers capable to provide adequate postoperative care.

    Breast augmentation offers a high rate of satisfaction but the local complications remain frequent. These are mainly capsular contracture, malpositions of implant, acute or infraclinical infections. The causes of these complications are multifactorials. The goal of this chapter is to determine the effect of the surgical technique on the result. We think that if no routine procedure can be proposed, a reflexion on the objectives of the breast augmentation and the adaptation of the surgical technique is necessary for each surgeon. We identify twelve aims and discuss them: rigorous preoperative planning, determination of the position of the implant, creation of an adapted implant pocket, as much atraumatic as possible dissection, no bacterial contamination, no foreign particles, respect of the implant, drainage or not, efficient suture, pain and discomfort control, need for contension and clear postoperative advices. These objectives being precised, we integrate them in a chronological surgical process under the form of questions. Each surgeon can then choose his answers by evaluating the arguments, which led to his choices.

    Necessary restorative requirements for full coverage are adequate axial wall height of the preparation for retention as well as sufficient vertical width of sound tooth structure cervically for the crown margins. In cases where adequate healthy tooth structure does not exist coronally to the epithelial attachment due to various crown damages, the margins of the crown might traumatize the periodontal attachment and the periodontium will be jeopardized iatrogenically. Teeth with inadequate axial Reight of the clinical crown, subgingival caries, vertical or horizontal fractures will require surgical crown lengthening procedures before prosthetic treatment is performed. These procedures may either involve only the soft tissues or bone remodeling as well. Irrespective of the procedure, crown lengthening must be performed with the objective of at least 3 mm. of healthy tooth structure coronally to the bone. This width will permit the formation of a new dentinogingival junction and the existence of 1-2 m.m. of sound tooth structure coronally to the new attachment line for the construction of a biologically acceptable crown margin. The purpose of this article is to discuss the clinical problem and underline the importance of crown lengthening procedures as a preparatory step for prosthetic treatment in fixed partial dentures.

    As extracorporeal membrane oxygenation (ECMO) is increasingly used for patients with cardiac and/or pulmonary failure, the need for noncardiac surgical procedures (NCSPs) in these patients will continue to increase. This study examined the NCSP required in patients supported with ECMO and determined which variables affect outcomes. The National Inpatient Sample Database was examined for patients supported with ECMO from 2007 to 2010. There were 563 patients requiring ECMO during the study period. Of these, 269 (47.8%) required 380 NCSPs. There were 149 (39.2%) general surgical procedures, with abdominal exploration/bowel resection (18.2%) being most common. Vascular (29.5%) and thoracic procedures (23.4%) were also common. Patients requiring NCSP had longer median length of stay (15.5 vs. 9.2 days, p = 0.001), more wound infections (7.4% vs. 3.7%, p = 0.02), and more bleeding complications (27.9% vs. 17.3%, p = 0.01). The incidences of other complications and inpatient mortality (54.3% vs. 58.2%, p = 0.54) were similar. On logistic regression, the requirement of NCSPs was not associated with mortality (odds ratio [OR]: 0.91, 95% confidence interval [CI]: 0.68-1.23, p = 0.17). However, requirement of blood transfusion was associated with mortality (OR: 1.70, 95% CI: 1.06-2.74, p = 0.03). Although NCSPs in patients supported with ECMO does not increase mortality, it results in increased morbidity and longer hospital stay.

    To explore whether surgical teams with greater stability among their members (ie, members have worked together more in the past) experience lower rates of sharps-related percutaneous blood and body fluid exposures (BBFE) during surgical procedures. A 10-year retrospective cohort study. A single large academic teaching hospital. Surgical teams participating in surgical procedures (n=333,073) performed during 2001-2010 and 2,113 reported percutaneous BBFE were analyzed. A social network measure (referred to as the team stability index) was used to quantify the extent to which surgical team members worked together in the previous 6 months. Poisson regression was used to examine the effect of team stability on the risk of BBFE while controlling for procedure characteristics and accounting for procedure duration. Separate regression models were generated for percutaneous BBFE involving suture needles and those involving other surgical devices. RESULTS The team stability index was associated with the risk of percutaneous BBFE (adjusted rate ratio, 0.93 [95% CI, 0.88-0.97]). However, the association was stronger for percutaneous BBFE involving devices other than suture needles (adjusted rate ratio, 0.92 [95% CI, 0.85-0.99]) than for exposures involving suture needles (0.96 [0.88-1.04]). Greater team stability may reduce the risk of percutaneous BBFE during surgical procedures, particularly for exposures involving devices other than suture needles. Additional research should be conducted on the basis of primary data gathered specifically to measure qualities of relationships among surgical team personnel.

  11. Soft Tissue Surgical Procedures for Optimizing Anterior Implant Esthetics

    Andreas L. Ioannou

    2015-01-01

    Full Text Available Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon’s rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

    Guidelines recommend surgical antibiotic prophylaxis for clean-contaminated procedures but none for clean procedures. The purpose of this study was to describe variations in surgical antibiotic prophylaxis for outpatient urological procedures at United States children's hospitals. Using the PHIS (Pediatric Health Information System®) database we performed a retrospective cohort study of patients younger than 18 years who underwent clean and/or clean-contaminated outpatient urological procedures from 2012 to 2014. We excluded those with concurrent nonurological procedures or an abscess/infected wound. We compared perioperative antibiotic charges for clean vs clean-contaminated procedures using a multilevel logistic regression model with a random effect for hospital. We also examined whether hospitals that were guideline compliant for clean procedures, defined as no surgical antibiotic prophylaxis, were also compliant for clean-contaminated procedures using the Pearson correlation coefficient. We examined hospital level variation in antibiotic rates using the coefficient of variation. A total of 131,256 patients with a median age of 34 months at 39 hospitals met study inclusion criteria. Patients undergoing clean procedures were 14% less likely to receive guideline compliant surgical antibiotic prophylaxis than patients undergoing clean-contaminated procedures (OR 0.86, 95% CI 0.84-0.88, p variation was seen for hospital level compliance with surgical antibiotic prophylaxis for clean-contaminated procedures (range 9.8% to 97.8%, coefficient of variation 0.36) than for clean procedures (range 35.0% to 98.2%, coefficient of variation 0.20). Hospitals that used surgical antibiotic prophylaxis appropriately for clean-contaminated procedures were likely to use surgical antibiotic prophylaxis inappropriately for clean procedures. More variation was seen in hospital level guideline compliance for clean-contaminated procedures. Copyright © 2017 American Urological

    Full Text Available The laryngeal mask airway (LMA is a supraglottic airway management device. The LMA is preferred for airway management in paediatric patients for short duration surgical procedures. The recently introduced ProSeal (PLMA, a modification of Classic LMA, has a gastric drainage tube placed lateral to main airway tube which allows the regurgitated gastric contents to bypass the glottis and prevents the pulmonary aspiration. This study was done to compare the efficacy of ProSeal LMA with an endotracheal tube in paediatric patients with respect to number of attempts for placement of devices, haemodynamic responses and perioperative respiratory complications. Sixty children, ASA I and II, weighing 10-20 kg between 2 and 8 years of age group of either sex undergoing elective ophthalmological and lower abdominal surgeries of 30-60 min duration, randomly divided into two groups of 30 patients each were studied. The number of attempts for endotracheal intubation was less than the placement of PLMA. Haemodynamic responses were significantly higher (P<0.05 after endotracheal intubation as compared to the placement of PLMA. There were no significant differences in mean SpO 2 (% and EtCO 2 levels recorded at different time intervals between the two groups. The incidence of post-operative respiratory complications cough and bronchospasm was higher after extubation than after removal of PLMA. The incidence of soft tissue trauma was noted to be higher for PLMA after its removal. There were no incidences of aspiration and hoarseness/sore throat in either group. It is concluded that ProSeal LMA can be safely considered as a suitable and effective alternative to endotracheal intubation in paediatric patients for short duration surgical procedures.

    Surgical skills and simulation courses are emerging to meet the demand for vascular simulation training for vascular surgical skills, but their educational effect has not yet been described. We sought to determine the effect of an intensive vascular surgical skills and simulation course on the procedural knowledge and self-rated procedural competence of vascular trainees and to assess participant feedback regarding the course. Participants underwent a 1.5-day course covering open and endovascular procedures on high-fidelity simulators and cadavers. Before and after the course, participants completed a written test that assessed procedural knowledge concerning index open vascular and endovascular procedures. Participants also assessed their own procedural competence in open and endovascular procedures on a 5-point Likert scale (1: no ability to perform, 5: performs independently). Scores before and after the course were compared among postgraduate year (PGY) 1-2 and PGY 3-7 trainees. Participants completed a survey to rate the relevance and realism of open and endovascular simulations. Fifty-eight vascular integrated residents and vascular fellows (PGY 1-7) completed the course and all assessments. After course participation, procedural knowledge scores were significantly improved among PGY 1-2 residents (50% correct before vs 59% after; P educational effect.

    Correction of leg length discrepancy during hip arthroplasty is a technical challenge. Although resurfacing proposed to young subjects presents a number of advantages (stability, bone stock, etc.), it does not correct leg length discrepancy. We propose an original femoral lengthening technique concomitant to resurfacing performed through the same approach, consisting in a Z-shaped subtrochanteric osteotomy. Resurfacing was performed first and the femoral and acetabular reaming material was used for autografting. The series comprised five cases followed for a mean 42.2 months (range, 33-64 months). The mean surgical time was 100 min (range, 76-124 min). Weightbearing was authorized in all cases at the 8th week. The mean lengthening was 32 mm (range, 25-40 mm). Healing was observed in all cases. This surgical technique, reserved for very young subjects who accept an 8-week postoperative period without weightbearing, can be proposed in cases with substantial preoperative leg length discrepancy.

  19. Novel surgical procedures in glaucoma: advances in penetrating glaucoma surgery.

    2008-03-01

    Despite late modifications and enhancements, traditional penetrating glaucoma surgery is not without complications and is reserved for patients in whom pharmacologic treatment and/or laser trabeculoplasty do not suffice to control the intraocular pressure. This article critically reviews recent advances in penetrating glaucoma surgery with particular attention paid to two novel surgical approaches: ab interno trabeculectomy with the Trabectome and implantation of the Ex-PRESS shunt. Ab interno trabeculectomy (Trabectome) achieves a sustained 30% reduction in intraocular pressure by focally ablating and cauterizing the trabecular meshwork/inner wall of Schlemm's canal. It has a remarkable safety profile with respect to early hypotonous or infectious complications as it does not generate a bleb, but it can be associated with early postoperative intraocular pressure spikes that may necessitate additional glaucoma surgery. The Ex-PRESS shunt is more commonly implanted under a partial thickness scleral flap, and appears to have similar efficacy to standard trabeculectomy offering some advantages with respect to the rate of early complications related to hypotony. Penetrating glaucoma surgery will continue to evolve. As prospective randomized clinical trials become available, we will determine the exact role of these surgical techniques in the glaucoma surgical armamentarium.

    2012-05-01

    General guidelines exist for the use of recombinant activated factor VII (rFVIIa) to maintain haemostasis during surgery in congenital haemophilia A and B patients with high responding inhibitors (CHwI). Individual surgical plans are required and based upon historical therapy response, adverse events and anticipated procedure. Surgical interventions are feasible, yet it remains unclear how many US hemophilia treatment centres (HTCs) perform procedures in this fragile population. To better understand the US HTC surgical experience in CHwI patients and the number/types of procedures performed, a 21-question survey was sent to 133 US HTCs, with follow-up for response clarification and to non-responders. 98/133 HTCs (74%) responded, with 87 currently treating CHwI patients. In the last decade, 76/85 HTCs performed 994 surgeries on CHwI patients. Sites were experienced in the following procedures: central line insertion/removal (73 HTCs), dental (58), orthopaedic (52), abdominal (23), cardiovascular (14) and otolaryngologic (11). Experience with orthopaedic surgeries included synovectomies - arthroscopic (23 HTCs), radioisotopic (22), and open (7); joint replacement (18); fracture repair (14); and arthrodesis (8). Treatment modalities included rFVIIa bolus (83 HTCs) or continuous infusions (9), plasma-derived activated prothrombin complex concentrate (pd-aPCC) (55), antifibrinolytics (51), topical haemostatic agents (29), factor VIII (16) and fibrin sealants (14). Protocols for bypassing agents were used by 31/92 (33%) HTCs. Most US HTCs surveyed care for CHwI patients (74%) and have experience in minor surgery; fewer HTCs reported complex orthopaedic surgical experience. Identification of best practices and surgical barriers is required to guide future initiatives to support these patients.

    Full Text Available Maria Adriana Cataldo, Nicola PetrosilloSecond Infectious Diseases Division, National Institute for Infectious Diseases, “Lazzaro Spallanzani”, Rome, ItalyAbstract: Fungi are a frequent cause of nosocomial infections, with an incidence that has increased significantly in recent years, especially among critically ill patients who require intensive care unit (ICU admission. Among ICU patients, postsurgical patients have a higher risk of Candida infections in the bloodstream. In consideration of the high incidence of fungal infections in these patients, their strong impact on mortality rate, and of the difficulties in Candida diagnosis, some experts suggest the use of antifungal prophylaxis in critically ill surgical patients. A clinical benefit from this strategy has been demonstrated, but the economic impact of the use of antifungal prophylaxis in surgical patients has not been systematically evaluated, and its cost–benefit ratio has not been defined. Whereas the costs associated with treating fungal infections are very high, the cost of antifungal drugs varies from affordable (ie, the older azoles to expensive (ie, echinocandins, polyenes, and the newer azoles. Adverse drug-related effects and the possibly increased incidence of fluconazole resistance and of isolates other than Candida albicans must also be taken into account. From the published studies of antifungal prophylaxis in surgical patients, a likely economic benefit of this strategy could be inferred, but its usefulness and cost–benefits should be evaluated in light of local data, because the available evidence does not permit general recommendations.Keywords: antifungal prophylaxis, cost-effectiveness, economics, surgery, fungal infection

    Full Text Available Ophthalmology is an expensive field and imaging is an indispensable modality in ophthalmology; and in developing countries including India, it is not possible for every ophthalmologist to afford slit-lamp photography unit. We here present our experience of slit-lamp photography using digital camera. Good quality pictures of anterior and posterior segment disorders were captured using readily available devices. It can be a used as a good teaching tool for residents learning ophthalmology and can also be a method to document lesions which at many times is necessary for medicolegal purposes. It's a technique which is simple, inexpensive, and has a short learning curve.

    Although atrial fibrillation is well tolerated by most patients, in some patients the consequences may be severe. The Maze procedure is a new open-heart operation that creates a carefully designed maze of incisions in the atrial myocardium; this maze then acts as an electrical conduit to channel atrial impulses from the sinoatrial node to the atrioventricular node. The Maze procedure has been shown to restore sinus rhythm and atrial systole (thus reducing the risk of thromboembolism), improve hemodynamics, alleviate palpitations, and eliminate the need for antiarrhythmic and anticoagulant drugs. We describe our first patient to undergo this operation.

  5. Surgical Treatment of Canine Glaucoma: Filtering and End-Stage Glaucoma Procedures.

    Maggio, Federica; Bras, Dineli

    2015-11-01

    Canine glaucoma is a common cause of vision loss associated with raised intraocular pressure, and leads to damage of the retina and optic nerve head. In most cases, medical treatment alone cannot provide long-term management of intraocular pressure control and preservation of vision. Surgical intervention is usually recommended to either decrease aqueous humor production, or increase its outflow. Among the current available procedures, filtering techniques are aimed at increasing aqueous humor outflow. Proper surgical timing and a combination of cyclodestructive and filtering procedures have been recently suggested to improve the long-term success of surgical treatment in dogs. Bleb fibrosis and surgical failure are still common occurrences in filtration surgery with relapse of glaucoma and vision loss. End stage procedures, such as enucleation, evisceration with intrascleral prosthesis, and chemical ablation of the ciliary bodies are then recommended to address chronic discomfort in buphthalmic and blind eyes.

    To evaluate the feasibility of incorporating hand-held computing technology in a surgical residency program, by means of hand-held devices for surgical procedure logging linked through the Internet to a central database. Division of General Surgery, University of Toronto. A survey of general surgery residents. The 69 residents in the general surgery training program received hand-held computers with preinstalled medical programs and a program designed for surgical procedure logging. Procedural data were uploaded via the Internet to a central database. Survey data were collected regarding previous computer use as well as previous procedure logging methods. Utilization of the procedure logging system. After a 5-month pilot period, 38% of surgical residents were using the procedure-logging program successfully and on a regular basis. Program use was higher among more junior trainees. Analysis of the database provided valuable information on individual trainees, hospital programs and supervising surgeons, data that would assist in program development. Hand-held devices can be implemented in a large division of general surgery to provide a reference database and a procedure-logging platform. However, user acceptance is not uniform and continued training and support are necessary to increase acceptance. The procedure database provides important information for optimizing trainees' educational experience.

    Yasuo Noda

    Full Text Available PURPOSE: To elucidate the merits of robotic application for vitreoretinal maneuver in comparison to conventional manual performance using an in-vitro eye model constructed for the present study. METHODS: Capability to accurately approach the target on the fundus, to stabilize the manipulator tip just above the fundus, and to perceive the contact of the manipulator tip with the fundus were tested. The accuracies were compared between the robotic and manual control, as well as between ophthalmologists and engineering students. RESULTS: In case of manual control, ophthalmologists were superior to engineering students in all the 3 test procedures. Robotic assistance significantly improved accuracy of all the test procedures performed by engineering students. For the ophthalmologists including a specialist of vitreoretinal surgery, robotic assistance enhanced the accuracy in the stabilization of manipulator tip (from 90.9 µm to 14.9 µm, P = 0.0006 and the perception of contact with the fundus (from 20.0 mN to 7.84 mN, P = 0.046, while robotic assistance did not improve pointing accuracy. CONCLUSIONS: It was confirmed that telerobotic assistance has a potential to significantly improve precision in vitreoretinal procedures in both experienced and inexperienced hands.

    The purpose of this study was to examine the volume and variability of noncardiac surgeries performed in children with congenital heart disease (CHD) requiring cardiac surgery in the first year of life. Patients who underwent cardiac surgery by 1 year of age and had a minimum 5-year follow-up at 22 of the hospitals contributing to the Pediatric Health Information System database between 2004 and 2012 were included. Frequencies of noncardiac surgical procedures by age 5 years were determined and categorized by subspecialty. Patients were stratified according to their maximum RACHS-1 (Risk Adjustment in Congenital Heart Surgery) category. The proportions of patients across hospitals who had a noncardiac surgical procedure for each subspecialty were compared using logistic mixed effects models. 8857 patients underwent congenital heart surgery during the first year of life, 3621 (41%) of whom had 13,894 noncardiac surgical procedures by 5 years. Over half of all procedures were in general surgery (4432; 31.9%) or otolaryngology (4002; 28.8%). There was significant variation among hospitals in the proportion of CHD patients having noncardiac surgical procedures. Compared to children in the low risk group (RACHS-1 categories 1-3), children in the high-risk group (categories 4-6) were more likely to have general, dental, orthopedic, and thoracic procedures. Children with CHD requiring cardiac surgery frequently also undergo noncardiac surgical procedures; however, considerable variability in the frequency of these procedures exists across hospitals. This suggests a lack of uniformity in indications used for surgical intervention. Further research should aim to better standardize care for this complex patient population.

    Patients with incurable malignancies can require surgical intervention. We prospectively evaluated patients treated with palliative surgery to qualitatively assess peri-operative outcomes. Eligible patients were assessed at a tertiary care cancer center. Demographic information and peri-operative morbidity and mortality were collected. Semi-structured qualitative interviews were obtained pre-operatively and post-operatively (1 month). Qualitative evaluation was performed using content analysis and an inductive approach. Twenty-eight patients were approached and 20 consented to interview. Data saturation was achieved after 14 patients. Median patient age was 58% and 56% were female. Peri-operative morbidity and mortality were 44% and 22%, respectively. "No other option" was seen as a dominant pre-operative theme (14 of 18). Other pre-operative themes included a "poor understanding of prognosis and the role of surgery in overall treatment plan". Post-operative themes included a "perceived benefit from surgery" and "satisfaction with decision-making", notwithstanding significant complications. Improved understanding of prognosis and the role of surgery were described post-operatively. Despite limited options and a poor understanding of prognosis, many patients perceived benefit from palliative surgery. However, peri-operative mortality was substantial. A robust and thorough patient-centered discussion about individual goals for surgery should be undertaken by surgeon, patient and family prior to embarking on a palliative operation.

    Surgical crown lengthening has been proposed as a means of facilitating restorative procedures and preventing injuries in teeth with structurally inadequate clinical crown or exposing tooth structure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biologic width. However, very little has been done in humans. Aims. The purpose of the study was to evaluate the potential changes in the periodontal tissues, particularly the biologic width, following surgical crown lengthening by two surgical procedures before and after crown placement. Methods and Material. Twenty (20) patients who needed surgical crown lengthening to gain retention necessary for prosthetic treatment and/or to access caries, tooth fracture, or previous prosthetic margins entered the study. The following parameters were obtained from line angles of treated teeth (teeth requiring surgical crown lengthening) and adjacent sites: Plaque and Gingival Indices (PI) & (GI), Position of Gingival Margin from reference Stent (PGMRS), Probing depth (PD), and Biologic Width (BW). Statistical Analysis Used. Student "t" Test. Results. Initial baseline values of biologic width were 2.55 mm (Gingivectomy procedure B1 Group) and 1.95 mm (Ostectomy procedure B2 Group) and after surgical procedure the values were 1.15 mm and 1.25 mm. Conclusions. Within the limitations of the study the biologic width, at treated sites, was re-established to its original vertical dimension by 3 months. Ostectomy with apically positioned flap can be considered as a more effective procedure than Gingivectomy for Surgical Crown Lengthening.

    1991-11-01

    Fifteen pair of commercially available gloves were tested under conditions that occur during radio frequency electrosurgery to determine their potential to cause burns or shocks. Two pair of gloves showed a hydration effect that produced sufficiently low direct current resistance, 1500 and 5000 ohms, to be a potential shock or burn hazard. All intact gloves passed in excess of 0.75 A of radio frequency current by capacitive coupling. Eleven pair of gloves displayed dielectric breakdown of the latex or neoprene at voltages between 2200 and 2600 volts; the remaining gloves ranged from 5800 to 7000 volts. Under specific conditions all gloves tested have the potential to cause burns or shocks to the surgeon during electrosurgical procedures. To avoid burns, shocks, or glove perforation, surgeons should be aware of situations that put them at high risk.

    A prototype manipulator system was developed for ophthalmologic microsurgery. The system, consisting of two parallel X-Y stages, can mechanically maintain a fixed-point of rotation at the surface of the eye, potentially reducing trauma during surgical procedures. The initial prototype was designed to function in concert with the da Vinci Surgical System for gross positioning. Robotic tests demonstrated the mechanical fitness of the prototype while an in vitro surgical sclerectomy was performed to demonstrate functionality of the approach.

    Full Text Available Mohanad Shukry, Jeffrey A MillerUniversity of Oklahoma Health Sciences Center, Department of Anesthesiology, Children’s Hospital of Oklahoma, Oklahoma City, OK, USAAbstract: Dexmedetomidine was introduced two decades ago as a sedative and supplement to sedation in the intensive care unit for patients whose trachea was intubated. However, since that time dexmedetomidine has been commonly used as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. This review focuses on the application of dexmedetomidine as a sedative and/or total anesthetic in patients undergoing procedures without the need for tracheal intubation. Dexmedetomidine was used for sedation in monitored anesthesia care (MAC, airway procedures including fiberoptic bronchoscopy, dental procedures, ophthalmological procedures, head and neck procedures, neurosurgery, and vascular surgery. Additionally, dexmedetomidine was used for the sedation of pediatric patients undergoing different type of procedures such as cardiac catheterization and magnetic resonance imaging. Dexmedetomidine loading dose ranged from 0.5 to 5 μg kg-1, and infusion dose ranged from 0.2 to 10 μg kg-1 h-1. Dexmedetomidine was administered in conjunction with local anesthesia and/or other sedatives. Ketamine was administered with dexmedetomidine and opposed its bradycardiac effects. Dexmedetomidine may by useful in patients needing sedation without tracheal intubation. The literature suggests potential use of dexmedetomidine solely or as an adjunctive agent to other sedation agents. Dexmedetomidine was especially useful when spontaneous breathing was essential such as in procedures on the airway, or when sudden awakening from sedation was required such as for cooperative clinical examination during craniotomies.Keywords: dexmedetomidine, sedation, nonintubated patients

    Isolated tricuspid valve (ITV) operations are infrequent and the decision to operate is controversial. We report a series of ITV operations to outline the current disease status requiring this uncommon procedure with an emphasis on the results of tricuspid valve repair (TVr) versus replacement (TVR). Using our prospective cardiac surgery database, 57 patients who underwent ITV operations between 01/02-03/14 were identified. Median follow up time was 3.5 years [interquartile range (IQR), 0.8-6.7 years]. Fifty-seven patients underwent ITV surgery with a mean age of 54.4±14.9 yrs and 61% were women. Baseline characteristics were similar between patients who underwent TVr (n=18) or TVR (n=39). The etiologies of TV dysfunction were: ITV endocarditis 14/57 (25%), persistent TV regurgitation after left-sided valve surgery in 12/57 (21%), traumatic biopsies and iatrogenic injury from pacing leads in 11/57 (19%), orthotopic heart transplant 9/57 (16%), carcinoid syndrome 3/57 (5%), congenital 2/57 (5%) and idiopathic 5/57 (9%). Overall, 32/57 (56%) patients had prior heart surgery; of which 10/32 (31%) were TV procedures. Bioprosthetic prostheses were used in 34/39 (87%) patients. Of those who had repair, 11/18 (61%) had ring annuloplasty, 3/18 (17%) bicuspidization, and 3/18 (17%) De Vega annuloplasty and one had vegetectomy. Operative mortality was 5.1% (n=2) and 16.7% (n=3) for TVR and TVr groups, respectively (P=0.32), with an overall mortality rate of 8.6%. Postoperative complications included new onset renal failure in 6/39 (15%) of TVr and 2/18 (11%) of TVR (P=0.71) and there were no strokes. Overall survival rates and degree of residual RV dysfunction were similar for the two groups (both P=0.3). Five-year survival was 77% and 84% for TVr and TVR respectively (P=0.52). There was no difference in rates of recurrent tricuspid regurgitation for TVr and TVR (35.7% vs. 23.5%, respectively, P=0.4). ITV surgery is associated with improved but still relatively high

    There is a need for more uniform, structured education focused on surgical procedures. We offer a standardized, step-by-step, web-based procedural training method with which surgeons can train more interns efficiently. The basis of this learning method is formed by 3D films in which surgical procedures are performed in clearly defined steps and the anatomic structures behind the surgical operating planes are further dissected. This basis is supported by online modules in which, aside from the operation, preparation and postoperative care are also addressed. Registrars can test their knowledge with exams. Trainers can see what the registrars studied, how they scored and how they progressed with their clinical skills. With the online portfolio we offer building blocks for certification and accreditation. With this clearly structured research method of constant quality, registrars are less dependent on the local trainer. In addition, through better preparation, the operation capacity can be used more efficiently for the training.

    Full Text Available Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

    2013-01-01

    Surgical procedures for the surgical management of duodenal ulcer had evolved through many stages, over the years. It started with gastroenterostomy alone, then followed by subtotal gastrectomy, vagotomy alone, vagotomy and gastro-jejunostomy, vagotomy and pyloroplasty, and highly selective vagotomy - all which started as open surgical procedures. Now unless there are complications the treatment is essentially medical following the work of Marshall and Warren. Currently, even when surgery is indicated, minimal invasive procedures are preferred. Four main types of pyloroplasties are well known. They are Weinberg, Heinecke-Mikulicz, Finney and Jaboulay. Vagotomy can be truncal, selective, and highly selective. Accepted surgical treatment for gastric ulcer is the distal gastric resection to include the ulcerated area, but not resecting more than 50-60% of the stomach. In the uncommon cases of Zollinger-Ellison syndrome, aggressive gastric surgery, the use of drugs, and the resection of the tumour have all been recommended in appropriate cases. With the discovery of Helicobacter pylori and its effective medical treatment, surgery has little role in the initial management of peptic ulcer disease. The place of the history of the surgical procedures employed earlier in the treatment of this disease would remain relevant.

    The introduction of telemanipulator systems into cardiac surgery enabled the heart surgeon to perform minimally invasive procedures with high precision and stereoscopic view. For further improvement and especially for inclusion of autonomous action sequences, implementation of force-feedback is necessary. The aim of our study was to provide a robotic scenario giving the surgeon an impression very similar to open procedures (high immersion) and to enable autonomous surgical knot tying with delicate suture material. In this experimental set-up the feasibility of autonomous surgical knot tying is demonstrated for the first time using stereoscopic view and force feedback. Copyright 2005 John Wiley & Sons, Ltd.

    Full Text Available Introduction This paper deals with otologic surgical procedures performed in a an Ear, Nose and Throat Depertment during a 15-year period. The authors compared the number of otologic surgical procedures with the number of laryngomicroscopies and procedures performed in Waldeyer's ring. RESULTS From January 1, 1987 to December 31, 2001, 1184 patients underwent the following surgical procedures in total endotracheal anesthesia: 285 paracenteses, 473 ventilation tubes insertions, 175 antrotomies or mastoidectomies, 194 tympanoplasties, 34 radical mastoidectomies, 4 facial nerve decompressions, 5 exostoses or osteoma of the external auditory canal operations and 14 stapedectomies. DISCUsSION Otologic surgical procedures are presented in table 1. In Yugoslav literature Topolac reports approximately 700 tympanoplasties in a 10-year period (1968-1978. Radonjić and associates report 2272 ear operations in the period 1975-1985. Distribution of operations is presented in table 2, whereas in table 3 we can see that the number of operated ears is much greater than the number of operated patients. CONCLUSION We think that the number of operations is not bigger, because we operate only in critical cases. Our human and technical resources should provide advanced ear microsurgery, but only with financial and organizational support.

    Despite the fact that ophthalmology is one of the foremost branches of medicine, conceptualization of the structure and function of the eye barely advanced in ancient Western civilizations. At the early recovery of Persian civilization (9(th) century AD) after the extinction of the Sassanid Empire (7(th) century AD), translations of Greek medical textbooks played an important role in the development of medicine and the emergence of great Persian physicians such as Rhazes, Avicenna and others. Rhazes was a leading Persian physician whose medical teachings have as yet not been thoroughly explored. In addition to numerous books and articles in various fields, he authored a great medical Encyclopedia (al-Hawi al-Kabir) in 25 volumes. In this article, we are going to compare Rhazes' particular viewpoints about ophthalmology with those of other famous Persian physicians and some recent essays and textbooks. For this purpose we reviewed Rhazes' second volume of al-Hawi that is dedicated exclusively to ophthalmology and contains some major topics of ophthalmology including anatomy, physiology, pathology, diseases, disorders and treatments. Important themes were carefully extracted and compared with the tenets of modern ophthalmology. After collating Rhazes' viewpoints with the latest findings in this field, it was concluded that he had brilliantly written about the signs and symptoms, etiology and treatment of many eye disorders more than a thousand years ago. The amazing point is that there was no accurate equipment at the time to help him in his investigations. This study proved that Rhazes' theories conform to recent knowledge about ophthalmology in many aspects, and could therefore be the subject of further investigations.

    There are different views on the effects of resident involvement on surgical outcomes. We hypothesized that resident participation in surgical care does not appreciably alter outcomes. We analyzed an American College of Surgeons NSQIP subset of inpatients having procedures with high complexity, including 4 surgical specialties (general surgery, cardiothoracic surgery, neurosurgery, and vascular surgery) with the highest mean work relative value units. We evaluated surgical outcomes in patients having procedures performed by the attending surgeon alone, or by the attending surgeon with assistance from at least one surgical resident (PGY1 to PGY≥6). Outcomes measures included operative mortality, composite morbidity, and failure to rescue (FTR). Propensity-score matching minimized the effects of nonrandom assignment of residents to procedures. In 266,411 patients, unmatched comparisons showed significantly higher operative mortality and composite morbidity rates, but decreased FTR, in operations performed with resident involvement. After propensity-score matching, there were small but significant resident-related increases in composite morbidity, but significant improvement in FTR. Senior-level resident involvement translated into improved outcomes, especially in cardiothoracic surgery procedures where >63.6% of procedures had PGY≥6 resident involvement. Resident involvement attenuated the significant worsening of operative mortality and FTR associated with multiple serious complications in individual patients. Measures of resource use increased modestly with resident involvement. We found substantial improvement in FTR with resident involvement, both in unmatched and propensity-matched comparisons. Senior-level resident participation seemed to attenuate, and even improve, surgical outcomes, despite slightly increased resource use. These results provide some reassurance about teaching paradigms.

    Generally, surgical treatment is recommended for Rockwood type 5 traumatic acromioclavicular joint dislocations. Since 1980, the authors have performed the modified Dewar procedure, the modified Cadenat procedure, and anatomical reconstruction of the coracoclavicular ligaments for this injury. The goal of this study was to determine the ideal surgical procedure for acromioclavicular joint dislocations by comparing these 3 procedures. The modified Dewar procedure was performed on 55 patients (Dewar group), the modified Cadenat procedure was performed on 73 patients (Cadenat group), and anatomical reconstruction of the coracoclavicular ligaments was performed on 11 patients (reconstruction group). According to the UCLA scoring system, therapeutic results averaged 27.3 points in the Dewar group, 28.2 in the Cadenat group, and 28.4 in the reconstruction group. The incidence of residual subluxation or dislocation in the acromioclavicular joint was evaluated at final radiographic follow-up. Subluxation occurred in 21 patients in the Dewar group, 18 in the Cadenat group, and 3 in the reconstruction group. Dislocation occurred in 3 patients in the Dewar group. Osteoarthritic changes in the acromioclavicular joint occurred in 20 patients in the Dewar group, 9 in the Cadenat group, and 1 in the reconstruction group. The modified Cadenat procedure can provide satisfactory therapeutic results and avoid postoperative failure or loss of reduction compared with the modified Dewar procedure. However, the modified Cadenat procedure does not anatomically restore the coracoclavicular ligaments. Anatomic restoration of both coracoclavicular ligaments can best restore acromioclavicular joint function. Copyright 2013, SLACK Incorporated.

  8. Guidelines on the facilities required for minor surgical procedures and minimal access interventions.

    2012-02-01

    There have been many changes in healthcare provision in recent years, including the delivery of some surgical services in primary care or in day surgery centres, which were previously provided by acute hospitals. Developments in the fields of interventional radiology and cardiology have further expanded the range and complexity of procedures undertaken in these settings. In the face of these changes there is a need to define from an infection prevention and control perspective the basic physical requirements for facilities in which such surgical procedures may be carried out. Under the auspices of the Healthcare Infection Society, we have developed the following recommendations for those designing new facilities or upgrading existing facilities. These draw upon best practice, available evidence, other guidelines where appropriate, and expert consensus to provide sensible and feasible advice. An attempt is also made to define minimal access interventions and minor surgical procedures. For minimal access interventions, including interventional radiology, new facilities should be mechanically ventilated to achieve 15 air changes per hour but natural ventilation is satisfactory for minor procedures. All procedures should involve a checklist and operators should be appropriately trained. There is also a need for prospective surveillance to accurately determine the post-procedure infection rate. Finally, there is a requirement for appropriate applied research to develop the evidence base required to support subsequent iterations of this guidance.

    To compare patient-reported outcome measures (PROMs) after different dental surgical procedures over a 1-week post-surgical period and in relation to duration of the surgery, and periosteal releasing incisions. To evaluate the prevalence of post-surgical complications. Four hundred and sixty-eight healthy dental patients requiring surgeries, such as crown lengthening (CL), open flap debridement (OFD) and implant installation (IMP) in the National Dental Centre, Singapore (2009-2011), were consecutively recruited. PROMs on bleeding, swelling, pain and bruising were obtained using Visual Analogue Scales (VAS) on days 0, 3, 5 and 7 post-operatively. On the day of surgery, the IMP procedure gave the lowest median VAS for all four PROM parameters. After a week, OFD still had a significantly higher VAS for swelling, pain and bruising. Patients who underwent procedures lasting more than 60 min. had higher VAS for all parameters except bleeding. After considering other important confounders, type of surgery procedure was no longer associated with the VAS score for any of the parameters. Time after surgery, male gender and shorter surgery duration reduced post-operative VAS for one or more of the parameters. Longer surgeon experience helps reduce VAS scores only for bleeding. Prevalence for tenderness to palpation was 11.6%, 8.9% and 12.2% for IMP, CL and OFD, respectively, 1-week post-operatively. Swelling and suppuration occurred rarely. The median VAS scores for all PROM parameters were generally low and reduced to near zero over a week following all three surgical procedures tested. Time after surgery and shorter surgery duration were associated with lower VAS scores in all the PROM parameters in this cohort of patients. Surgery type was not associated significantly with VAS after adjustment with other important confounders. Low prevalences of post-surgical complications were reported. © 2014 John Wiley & Sons A/S.

    Thoracic surgical procedures can be either thoracotomy or thoracoscopy. In thoracotomy, the incision could be either muscle-cutting or muscle-sparing incision. The posterolateral thoracotomy incision is used for most general thoracic surgical procedures. This incision, which involves division of the latissimus dorsi and serratus anterior muscles, affords excellent exposure of the thoracic cavity. However, it is associated with significant morbidity, including impaired pulmonary function, postoperative chest pain, and restricted arm and shoulder movement. Various muscle-sparing incisions have been proposed to decrease the morbidity. Postthoracotomy pain originates from pleural and muscular damage, costovertebral joint disruption, and intercostal nerve damage during surgery. Inadequate pain relief after surgery affects the quality of patient's recovery and exposes the patients to postoperative morbidities. There is a tendency nowadays among thoracic surgeons and anesthesiologists toward the area of enhanced recovery after thoracic surgery which requires careful titration of the anesthetic drugs in awake patients undergoing thoracoscopic procedures. There is a common feeling among thoracic anesthesiologists that potthoracoscopy procedures produce less pain intensity versus thoracotomy which is partially true. However, effective management of acute pain following either thoracotomy/thoracoscopy is needed and may prevent these complications and reduce the likelihood of developing chronic pain. In this report, we are going to review the newly introduced postthoracotomy/thoracoscopy pain relief modalities with special reference to the new tendency of awake thoracic surgical procedures and its impact on enhanced recovery after surgery.

    Arthrodesis is the most reliable and durable surgical procedure for the treatment of a joint disorder, with the main disadvantage of loss of motion of the fused joint. The distal radioulnar joint can be arthrodesed, while forearm pronation and supination are maintained or even improved by creating a pseudoarthrosis of the ulna just proximal to the arthrodesis. This is known as the Sauvé-Kapandji procedure. This procedure is not void of possible complications, such as nonunion or delayed union of the arthrodesis, fibrous or osseous union at the pseudoarthrosis, and painful instability at the proximal ulna stump. All of these can be prevented if a careful surgical technique is used. Copyright © 2010 Elsevier Inc. All rights reserved.

    Full Text Available INTRODUCTION: There are various procedures available for ptosis correction. Successful outcome not only depends on correct technique but also choosing appropriate procedure for each patient. Selection of procedure is based on available levator function and also other factors like etiology, severity, Bell’s phenomenon etc. If such varied procedure s are performed in a group of patients based on standard criteria and results are evaluated systematically we can determine what works best for a given patient . AIM : Evaluation of outcome of various surgical procedures for upper eyelid ptosis . METHODOLOGY : 25 eyelids of 20 patients who presented to a tertiary centre in south India with complaint of drooping of upper lid were considered. All subjects underwent complete ocular examination corrected visual acuity and detailed ptosis evaluation with particular emphasis on measurement of levator muscle function, MRD1 (margin reflex distance - 1, palpebral fissure width in different gazes and margin crease distance. The effect of various factors like MRD1, MCD, levator function were assessed, the amount of correction required and appropriate surgical procedure was chosen. Surgical procedure of Levator resection, frontalis sling operation, anterior levator aponeurosis advancement, o r other ptosis correction procedures under appropriate anaesthesia were performed. Post - operative evaluation in terms of visual acuity, MRD, Interpalpebral fissure height, lid symmetry, lagophthalmos and complications (if any was done. RESULTS : Levator muscle resection was done in 28% of eyelids, frontal sling surgery in 60% of eyelids, Levator muscle plication in 8% eyelids and levator muscle disinsertion with frontal sling surgery in 4% eyes. Undercorrection was seen in about 44% of eyelids in varying degrees. 56% of the eyes had optimal correction. Symmetric correction was achieved in 76% of eyelids.

    LENUS (Irish Health Repository)

    Laing, Tereze A

    2012-02-01

    BACKGROUND: The surgical management of pressure ulcers traditionally involved staged procedures, with initial debridement of necrotic or infected material followed by reconstruction at a later date when the wound was deemed viable and free of gross infection. However, over the past decade, it has been suggested that a single-stage procedure, combining initial debridement and definitive reconstruction, may provide advantages over staged surgery. We present our experience with the staged approach and review the current evidence for both methods. SUBJECTS AND SETTINGS: : We reviewed medical records of all patients referred to our service for pressure ulcer management between October 2001 and October 2007. The National Rehabilitation Hospital is the national center in Ireland for primary rehabilitation of adults and children suffering from spinal and brain injury, serving patients locally and from around the country. METHODS: All subjects who were managed surgically underwent a 2-stage procedure, with initial debridement and subsequent reconstruction. The main outcome measures were length of hospital stay, postoperative morbidity and mortality, and time to complete ulcer healing. RESULTS: Forty-one of 108 patients with 58 pressure ulcers were managed surgically. All patients underwent initial surgical debridement and 20 patients underwent subsequent pressure ulcer reconstruction. Postreconstructive complications occurred in 5 patients (20%). The mean time to complete ulcer healing was 17.4 weeks. Partial flap necrosis occurred in 3 patients, but there were no episodes of flap failure. CONCLUSIONS: We achieved favorable results with a 2-stage reconstruction technique and suggest that the paucity of evidence related to single-stage procedures does not support a change in surgical management.

    With a thorough knowledge of the anatomy of the foot, and basic surgical instruments, digit surgery can be performed in field situations. Sepsis of the distal interphalangeal and proximal interphalangeal joints should be treated surgically because conservative treatment is often ineffective. Most of the diseases described in this article are chronic and often the animals have been suffering for some time. Perioperative analgesia is important to alleviate the pain of those animals. All those procedures should be performed under local or regional anesthesia. Copyright © 2017 Elsevier Inc. All rights reserved.

    2011-02-01

    Fee splitting and co-management are common practices in ophthalmology. These arrangements may conflict with the ethical principles governing the doctor-patient relationship, may constitute professional misconduct, and at times, may be illegal. Implications and perceptions of these practices may vary between different cultures. Full disclosure to the patient may minimize the adverse effects of conflicts of interest that arise from these practices, and may thereby allow these practices to be deemed acceptable by some cultural morays, professional guidelines, or by law. Disclosure does not necessarily relieve the physician from a potential ethical compromise. This review examines the practice of fee splitting in ophthalmology, its legal implications, the policies or guidelines governing such arrangements, and the possible ethical ramifications. A comparative view between 3 countries, Canada, the United States, and Oman, was conducted; illustrating that even in disparate cultures, there may be some universality to the application of ethical principles.

    The Agency for Healthcare Research and Quality and the Leapfrog Group use hospital procedure volume as a quality measure for pancreatic resection (PR), abdominal aortic aneurysm (AAA) repair, esophageal resection (ER), and coronary artery bypass grafting (CABG). However, controversy exists regarding the strength and validity of the evidence for the volume-outcome association. The purpose of this study was to reevaluate the volume-outcome relationship for these procedures. Discharge data for 261,412 patients were extracted from the 2008 Nationwide Inpatient Sample. The relationship between hospital procedure volume and mortality was rigorously assessed using hierarchical general linear modeling with restricted cubic splines, adjusted for patient demographics, comorbid disease, and elective procedure status. Unadjusted mortality rates were PR (4.7%), AAA (12.7%), ER (5.8%), and CABG (2.2%), and the majority of operations were elective. Hospital procedure volume was not a statistically significant predictor of in-hospital mortality for any of the 4 procedures. Strong predictors of mortality included age, elective procedure status, renal failure, and malnutrition (P procedure volume is not a significant predictor of mortality for the performance of pancreatectomy, AAA repair, esophagectomy, or CABG. Procedure volume by itself should not be used as a proxy measure for surgical quality. Patient mortality risk is primarily attributable to patient-level characteristics such as age and comorbidity.

    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

    There are two basic approaches for the surgical correction of presbyopia: increasing depth of focus (e.g. by means of multifocal laser abrasion of the cornea), Or restoring accommodation in the sense of a dynamic change in ocular refraction (accommodative intraocular lenses, scleral expansion). Pseudoaccommodative procedures are able to achieve satisfactory near vision, albeit at the price of lower performance in the intermediate range and decreased image quality. The restoration of accommodation remains problematic, partly because the mechanism of accommodation and the development of presbyopia are still not fully understood. Some surgical procedures are based on concepts, the validity of which is not confirmed or which even contradict experimental evidence. Thus, it is necessary to assess the results and presumed mechanisms critically and objectively.

    To analyse the trend in ambulatory surgery procedures in Catalonia (Spain) hospitals with regard to the activity in inpatient care units and structural resources in surgery. A descriptive study was performed using data from the Statistics of Health Facilities with Inpatient Care of the Health Department of the Catalan Government from 2001 to 2011. Data from acute care hospitals were analysed and were classified in public and private hospitals. The percentage of ambulatory surgical procedures increased by 63.2% and the percentage of inpatient surgery decreased by 23.5% (this trend was more pronounced in public hospitals). This result coincided with a decrease of structural resources in surgery (beds and operating rooms) and with an improvement in inpatient surgical activity (a decrease in the mean length of stay and bed occupancy rate in all hospitals). Structural surgery resources were optimized and efficiency was improved in surgery inpatient care units. Copyright © 2015 SESPAS. Published by Elsevier Espana. All rights reserved.

    Organized health services in Bosnia and Herzegovina started with the foundation of several vakuf hospitals (in Sarajevo, Tuzla, Banja Luka, Mostar and Travnik) financed by the fund of the Gazi Husrev-beg vakuf. In these hospitals services was provided by the qualified health professionals, mainly educated at the schools of medicine in Turkey, Italy, Austria, Hungary, Switzerland and other countries. Majority of them worked as civil and military physicians in the above mentioned vakuf hospitals, but also in the Turkey army hospitals situated in the all larger settlements in Bosnia and Herzegovina. During the period when B&H was managed by the Turkey and Austro-Hungarian empire there was no specialized ophthalmology services. During the Austro-Hungarian management there was a Surgical-oculist department within the Land Hospital in Sarajevo, which treated 4.47% of patients with eye diseases, among total number of in-patients, and according to the health service at the end of year 1900, during that year there there was 3238 general surgeries and 633 ophthalmology surgeries performed. In the Kingdom of Yugoslavia, beside establishment of the independent Eye department within the General State hospital in Sarajevo, in1923, also started development of the ophthalmology service within Surgical Department in Mostar, which was lead in 1929 by the ophthalmologist, and which grew in 1931 into independent Eye Department, as the second of that type in B&H. Specialized ophthalmology service in Banja Luka started to develop within the Surgery Department in 1931, and independent Eye Department was founded in 1945. Medical Faculty in Sarajevo was founded on 16th November 1946. Also on founded on the same day is the Eye Clinic, and appointed as its first director was Professor Vladimir Cavka MD., one of the first full time professors of the Medical Faculty in Sarajevo, founder of the Peoples society of B&H (Academy of Sciences and Arts of B&H) and the magazine, Medicinski arhiv

    It is well established that emotions are organized around two motivational systems: the defensive and the appetitive. Individual differences are relevant factors in emotional reactions, making them more flexible and less stereotyped. There is evidence that health professionals have lower emotional reactivity when viewing scenes of situations involving pain. The objective of this study was to investigate whether the rating of pictures of surgical procedure depends on their personal/occupational relevance. Fifty-two female Nursing (health discipline) and forty-eight Social Work (social science discipline) students participated in the experiment, which consisted of the presentation of 105 images of different categories (e.g., neutral, food), including 25 images of surgical procedure. Volunteers judged each picture according to its valence (pleasantness) and arousal using the Self-Assessment Manikin scale (dimensional approach). Additionally, the participants chose the word that best described what they felt while viewing each image (discrete emotion perspective). The average valence score for surgical procedure pictures for the Nursing group (M = 4.57; SD = 1.02) was higher than the score for the Social Work group (M = 3.31; SD = 1.05), indicating that Nursing students classified those images as less unpleasant than the Social Work students did. Additionally, the majority of Nursing students (65.4%) chose "neutral" as the word that best described what they felt while viewing the pictures. In the Social Work group, disgust (54.2%) was the emotion that was most frequently chosen. The evaluation of emotional stimuli differed according to the groups' personal/occupational relevance: Nursing students judged pictures of surgical procedure as less unpleasant than the Social Work students did, possibly reflecting an emotional regulation skill or some type of habituation that is critically relevant to their future professional work.

    Prolonged preoperative fasting can be associated with adverse outcomes, particularly in children. Our aims were to assess the time pediatric patients fasted prior to surgical or radiologic procedures and evaluate whether fasting (NPO) orders complied with national guidelines. We measured NPO start time, time of last intake, and time test or surgery was scheduled, took place, or was cancelled in 219 pediatric patients. Findings demonstrate that pediatric patients experienced prolonged fasting before procedures and that the majority of NPO orders were non-compliant with national guidelines. We have developed strategies to reduce fasting times and ensure compliance with recommended national fasting standards.

    Patients with a cleft lip or palate often present alterations in the labial aspect of the ridge, resulting in a shallow vestibule. This study compares the results of two different surgical procedures on deepening of the labial sulcus. Ten patients with a cleft lip and palate were separated into two groups and underwent different vestibuloplasty procedures. An experimental group used a removable retention splint. Preoperative and 4-month postoperative sulcus heights were measured and analyzed statistically. No statistically significant differences could be detected between groups. The results indicated that to reach consistent results, a larger number of patients must be submitted to this evaluation.

HEMOPATCH (Sealing Hemostat is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG. NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

    In order to examine whether thorough surgical hand disinfection (handwashing plus hand disinfection) between consecutive operations is necessary, tests were carried out simulating normal clinical conditions. The tests were performed according to the guidelines for the evaluation of disinfection procedures of the German Society for Hygiene and Microbiology. Surgical hand disinfection was as follows: handwashing with soap without antimicrobial additives and subsequent 5-min disinfection with 60% n-propanol. This was followed by simulated operations of 30 or 120 min duration with a 30-min break between operations, during which half of the test group kept on the surgical gloves, while the other half removed them. The second surgical hand disinfection was done without prior handwashing by 50% of the test group. The disinfection time was reduced from 5 to 1 min by 50% of the test group. The results were evaluated by means of explorative data analysis and inductive statistical methods. Removing the surgical gloves during the interoperative break did not result in significantly higher numbers of colony forming units (cfu) compared with retaining the gloves. This was also the case after a subsequent handwashing. At the second surgical hand disinfection, after a simulated operation of 60 min duration (including break), there was no significant difference in the numbers of cfus between the test group who had washed their hands and those who had not. Reducing the disinfection time from 5 min to 1 min was not associated with a significant increase in the number of cfus. However, after a simulated operating time of 150 min (including the break), the second surgical hand disinfection with handwashing resulted in a significantly lower number of microorganisms than disinfection alone. In half the tests, the numbers of cfu were significantly lower when the test group disinfected their hands for 5 min rather than 1 min.

    Full Text Available BACKGROUND Dexmedetomidine, an α2 agonist is an approved drug for sedation and co-analgesia, but may cause hypotension and bradycardia. Ketamine, which provides profound analgesia and dissociative anaesthesia when used with dexmedetomidine may counteract the adverse haemodynamic effects as both have opposing actions on the cardiovascular system apart from providing satisfactory sedation and analgesia during minor surgical procedures. OBJECTIVE To study the sedoanalgesic efficacy and haemodynamic changes of dexmedetomidine infusion along with subanaesthetic dose of ketamine for minor surgical procedures. MATERIALS AND METHODS After Institutional Ethical Committee approval and informed patient consent, 30 ASA physical status I and II patients of age between 20-50 years planned for split skin grafting were selected and included in the study, which was done over a period of four months. The patients were given continuous infusion of loading dose of dexmedetomidine of 1 µg/kg over 10 minutes. Ketamine 0.8 mg/kg IV was given one minute before the start of the procedure and subsequently maintained with dexmedetomidine infusion @ 0.5 µg/kg/hr. Pain and sedation score, haemodynamic changes, requirement of additional dose of ketamine, and occurrence of emergence delirium were observed. RESULTS The sedation level during the procedure and the pain score in the immediate postoperative period were satisfactory. 28 patients did not have any discomfort whereas 2 patients required additional 0.8 mg/kg of IV ketamine. Hypotension occurred in 3 patients and bradycardia in 2 patients. There was nausea in 2 patients whereas emergence delirium or respiratory depression was not seen in any of the patients. CONCLUSION Dexmedetomidine infusion with subanaesthetic dose of ketamine can be used satisfactorily for minor surgical procedures.

    Full Text Available Introduction: Preservation of the health of periodontium is very important for the long-term success of restored teeth and a balance should always be created between the patients’ esthetic requirements and the periodontal health. Failures of crown lengthening procedures are classified into early and late failures. The aim of this study was to evaluate the prevalence of early failures of crown leathering surgical procedures. Materials and methods: In this descriptive/cross-sectional study, 96 patients were selected from those referring to the Department of Periodontitis, Tabriz Faculty of Dentistry, who required crown lengthening procedures. The particulars of these patients were recorded in special forms and the reasons for the failure of surgical procedures were separately determined at 2- and 6-week intervals. In addition, the frequencies of the reasons for failures were determined in percentages and absolute frequencies. Data were analyzed with descriptive statistics (frequencies and percentages using SPSS 21. Statistical significance was set at P<0.05. Results: Evaluation of patients 6 weeks after surgery showed a failure rate of 14.5% for crown lengthening procedures in patients referring to the Department of Periodontics, Tabriz Faculty of Dentistry. The most common reasons for such early failures in the 6th week, in descending order, were a lack of sufficient keratinized gingiva around in tooth in question, fracture of the tooth structure after surgery, inadequate surgery (not creating a proper distance between the healthy margin and the crest and the coronal returning of the gingival tissue on the tooth. A lack of sufficient keratinized gingiva around the tooth was the most frequent reason for the early failure of crown lengthening procedure at both study intervals. Conclusion: It can be concluded from the results of the present study that during the 6th postoperative week the crown lengthening procedures exhibited a 14.5% failure rate

    To determine the usefulness and safety of radiological placement of a central venous catheter by prospectively comparing the results of interventional radiology and blind surgery. For placement of a central venous catheter, the blind surgical method was used in 78 cases (77 patients), and the interventional radiological method in 56 cases (54 patients). The male to female ratio was 66:68, and the patients' mean age was 48 (range, 18-80) years. A tunneled central venous catheter was used in 74 cases, and a chemoport in 60. We evaluated the success and duration of the procedures, the number of punctures required, and ensuing complications, comparing the results of the two methods. The success rates of the interventional radiological and the blind surgical procedure were 100% and 94.8%, respectively. The duration of central catheterization was 3-395 (mean, 120) day, that of chemoport was 160.9 days, and that of tunneled central venous catheter was 95.1 days. The mean number of punctures of the subclavian vein was 1.2 of interventional radiology, and 2.1 for blind surgery. The mean duration of the interventional radiology and the blind surgical procedure was, respectively, 30 and 40 minutes. The postprocedure complication rate was 27.6% (37 cases). Early complications occurred in nine cases (6.7%): where interventional radiology was used, there was one case of hematoma, and blind surgery gave rise to hematoma (n=2), pneumothorax (n=2), and early deviation of the catheter (n=4). Late complications occurred in 32 cases (23.9%). Interventional radiology involved infection (n=4), venous thrombosis (n=1), catheter displacement (n=2) and catheter obstruction (n=5), while the blind surgical procedure gave rise to infection (n=5), venous thrombosis (n=3), catheter displacement (n=4) and catheter obstruction (n=8). The success rate of interventional radiological placement of a central venous catheter was high and the complication rate was low. In comparison with the blind

Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages.Keywords: presbyopia, surgical correction, treatment

    The surgical treatment of hepatopancreatobiliary (HPB) diseases requires complex operative procedures. Within the last decades the morbidity (36-50 %) and mortality (surgery shows an increased rate of complications. Postoperative bleeding has a major effect on the outcome and the incidence is 6.7 % after pancreatic surgery and 3.2 % after hepatobiliary surgery. The major causes of early postoperative hemorrhage are related to technical difficulties in surgery whereas late onset postoperative hemorrhage is linked to anastomosis insufficiency, formation of fistulae or abscesses due to vascular arrosion or formation of pseudoaneurysms. In many cases, delayed hemorrhage is preceded by a self-limiting sentinel bleeding. The treatment is dependent on the point in time, location and severity of the hemorrhage. The majority of early postoperative hemorrhages require surgical treatment. Late onset hemorrhage in hemodynamically stable patients is preferably treated by radiological interventions. After interventional hemostatic therapy 8.2 % of patients require secondary procedures. In the case of hemodynamic instability or development of sepsis, a relaparotomy is necessary. The treatment concept includes surgical or interventional remediation of the underlying cause of the hemorrhage. Other causes of postoperative morbidity and mortality are arterial and portal venous stenosis and thrombosis. Following liver resection, thrombosis of the portal vein occurs in 8.5-9.1 % and in 11.6 % following pancreatic resection with vascular involvement. Interventional surgical procedures or conservative treatment are suitable therapeutic options depending on the time of diagnosis and clinical symptoms. The risk of morbidity and mortality after HPB surgery can be reduced only in close interdisciplinary cooperation, which is particularly true for vascular complications.

    Surgical treatment of chronic pancreatitis is indicated for intractable pain. Frey's procedure is an accepted treatment for this disease. The aim of the present study was to describe a single-centre experience in the treatment of chronic pancreatitis using Frey's procedure. A retrospective analysis of 73 patients who underwent a Frey's procedure between 1991 to 2007 and had at least 1 year of follow-up. Demographics, indication for surgery, peri-operative complications and late outcomes were analysed. The median age was 39.9 years. Seventy out of the 73 (95.8%) patients were male. The median pre-operative body mass index (BMI) was 19.1 kg/m(2). All patients had abdominal pain, 34 (46.6%) of them daily and 13 (17.8%) weekly, with moderate or severe intensity in 98.6% (n= 72). The aetiology was secondary to alcohol in 70 patients (95.9%), with a median consumption of 278 g per day. The surgical morbidity rate was 28.7%; there were no deaths. Median post-operative follow-up was 77.0 months; 64 patients (91.4%) had complete pain relief and post-operative BMI was 22.4 kg/m(2) (P<0.001). All patients with pre-operative endocrine and exocrine insufficiencies showed no reversal of the situation. New onset insufficiencies appeared late. Frey's procedure was a safe and effective therapeutic option for the surgical treatment of patients with intractable pain caused by chronic pancreatitis. © 2011 International Hepato-Pancreato-Biliary Association.

    The fidelity of image-guided neurosurgical procedures is often compromised due to the mechanical deformations that occur during surgery. In recent work, a framework was developed to predict the extent of this brain shift in brain-tumor resection procedures. The approach uses preoperatively determined surgical variables to predict brain shift and then subsequently corrects the patient's preoperative image volume to more closely match the intraoperative state of the patient's brain. However, a clinical workflow difficulty with the execution of this framework is the preoperative acquisition of surgical variables. To simplify and expedite this process, an Android, Java-based application was developed for tablets to provide neurosurgeons with the ability to manipulate three-dimensional models of the patient's neuroanatomy and determine an expected head orientation, craniotomy size and location, and trajectory to be taken into the tumor. These variables can then be exported for use as inputs to the biomechanical model associated with the correction framework. A multisurgeon, multicase mock trial was conducted to compare the accuracy of the virtual plan to that of a mock physical surgery. It was concluded that the Android application was an accurate, efficient, and timely method for planning surgical variables.

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reason is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which has to include five requirements: visual fidelity, interactivity, physical properties, physiological properties, sensory input and output. In this report we will describe how to get a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction.

    Background: Complications after surgical procedures in patients with cardiac implantable electronic devices (CIED) are an emerging problem due to an increasing number of such procedures and aging of the population, which consequently increases the frequency of comorbidities. Objective: To identify the rates of postoperative complications, mortality, and hospital readmissions, and evaluate the risk factors for the occurrence of these events. Methods: Prospective and unicentric study that included all individuals undergoing CIED surgical procedures from February to August 2011. The patients were distributed by type of procedure into the following groups: initial implantations (cohort 1), generator exchange (cohort 2), and lead-related procedures (cohort 3). The outcomes were evaluated by an independent committee. Univariate and multivariate analyses assessed the risk factors, and the Kaplan-Meier method was used for survival analysis. Results: A total of 713 patients were included in the study and distributed as follows: 333 in cohort 1, 304 in cohort 2, and 76 in cohort 3. Postoperative complications were detected in 7.5%, 1.6%, and 11.8% of the patients in cohorts 1, 2, and 3, respectively (p = 0.014). During a 6-month follow-up, there were 58 (8.1%) deaths and 75 (10.5%) hospital readmissions. Predictors of hospital readmission included the use of implantable cardioverter-defibrillators (odds ratio [OR] = 4.2), functional class III­-IV (OR = 1.8), and warfarin administration (OR = 1.9). Predictors of mortality included age over 80 years (OR = 2.4), ventricular dysfunction (OR = 2.2), functional class III-IV (OR = 3.3), and warfarin administration (OR = 2.3). Conclusions: Postoperative complications, hospital readmissions, and deaths occurred frequently and were strongly related to the type of procedure performed, type of CIED, and severity of the patient's underlying heart disease.

    The recent surge of new legislation regulating induced abortion in the United States is ostensibly motivated by the desire to protect women's health. To provide context for interpreting the risk of abortion, we compared abortion-related mortality to mortality associated with other outpatient surgical procedures and selected nonmedical activities. We calculated the abortion-related mortality rate during 2000-2009 using national data. We searched PubMed and other sources for contemporaneous data on mortality associated with other outpatient procedures commonly performed on healthy young women, marathon running, bicycling and driving. The abortion-related mortality rate in 2000-2009 in the United States was 0.7 per 100,000 abortions. Studies in approximately the same years found mortality rates of 0.8-1.7 deaths per 100,000 plastic surgery procedures, 0-1.7deaths per 100,000 dental procedures, 0.6-1.2 deaths per 100,000 marathons run and at least 4 deaths among 100,000 cyclists in a large annual bicycling event. The traffic fatality rate per 758 vehicle miles traveled by passenger cars in the United States in 2007-2011 was about equal to the abortion-related mortality rate. The safety of induced abortion as practiced in the United States for the past decade met or exceeded expectations for outpatient surgical procedures and compared favorably to that of two common nonmedical voluntary activities. The new legislation restricting abortion is unnecessary; indeed, by reducing the geographic distribution of abortion providers and requiring women to travel farther for the procedure, these laws are potentially detrimental to women's health.

    Full Text Available Ronald H Silverman1,2 1Department of Ophthalmology, Columbia University Medical Center, 2F.L. Lizzi Center for Biomedical Engineering, Riverside Research, New York, NY, USA Abstract: The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via cilio-destruction, tumors, and other pathologies. Linear and annular transducer arrays offer synthetic focusing in which precise timing of the excitation of independently addressable array elements allows formation of a converging wavefront to create a focus at one or more programmable depths. Most recently, linear array-based plane-wave ultrasound, in which the array emits an unfocused wavefront and focusing is performed solely on received data, has been demonstrated for imaging ocular anatomy and blood flow. While the history of ophthalmic ultrasound extends back over half-a-century, new and powerful technologic advances continue to be made, offering the prospect of novel diagnostic capabilities.

    Antonio Scarpa (1752-1832) was a prominent scholar who contributed greatly to otolaryngology, orthopedics, ophthalmology, neuroanatomy, and surgery. In 1801, he published a textbook on ophthalmology, the first Italian textbook on this subject and the most propagated European ophthalmic textbook in the first half of the 19th century. The book included important descriptions of lacrimal system disorders, many oculoplastic procedures, and the first description of posterior staphyloma.

    Pre-operative red blood cell (RBC) transfusions are often recommended for patients with sickle cell disease (SCD) who require elective surgery under general anesthesia. However, definitive randomized studies demonstrating the benefit of transfusions in this setting have not been conducted. In particular, the merits of transfusion prior to minor or low-risk surgical procedures in children with SCD have not been demonstrated. We hypothesized that children with sickle cell anemia (Hb SS) who have minor elective surgical procedures develop few complications even without pre-operative transfusion. We accessed our Comprehensive Sickle Cell Program's Database to identify all such procedures performed during a 13-year period. Medical records were reviewed to characterize the surgical procedure, the use of transfusions, and perioperative complications. Twenty-eight children with Hb SS had a total of 38 minor surgical procedures. No perioperative transfusions were given in 34 of the cases (85%). Five of these 34 surgeries (15%) were associated with minor post-operative complications (fever or transient pain). No post-operative acute chest syndrome was encountered. Minor or low-risk elective surgical procedures in children with Hb SS may not routinely require pre-operative transfusion. A randomized clinical trial to compare transfusion with no transfusion for minor surgical procedures is needed.

    Complex laparoscopic procedures in urology are technically demanding with an extended learning curve. Robotic systems add significant cost to laparoscopic procedures. We therefore evaluated the use of the Radius Surgical System (RSS), a mechanical manipulator, for complex laparoscopic cases in urology. The RSS (Tuebingen Scientific) consists of two hand-guided surgical manipulators and provides a deflectable and rotatable tip allowing six degrees of freedom. We evaluated the system by using a series of standardized models in the pelvitrainer. We analyzed the effectiveness of the system and the learning curve. We then evaluated the system in the clinical setting during laparoscopic radical prostatectomy. Surgeons with experience on the RSS were compared to surgeons without previous experience on the system. We identified a learning curve in those participants without experience on the system only when performing complete anastomoses in the pelvitrainer. However, this learning curve included less than 10 anastomoses. The first clinical experiences during laparoscopic extraperitoneal radical prostatectomy (n=10) are promising. All anastomoses were patent on routine (X-ray) examination 8 days after surgery. The RSS system is easy to use and we identified a very short learning curve. We now optimize the system for use in urology. This device may facilitate complex laparoscopic procedures without the use of costly robotic systems and should be further evaluated in the experimental and clinical setting.

    Postoperative unplanned readmissions are costly and decrease patient satisfaction; however, little is known about this complication in pediatric surgery. The purpose of this study was to determine rates and predictors of unplanned readmission in a multi-institutional cohort of pediatric surgical patients. Unplanned 30-day readmissions following general and thoracic surgical procedures in children Pediatric. Time-dependent rates of readmission per 30 person-days were determined to account for varied postoperative length of stay (pLOS). Patients were randomly divided into 70% derivation and 30% validation cohorts which were used for creation and validation of a risk model for readmission. Readmission occurred in 1948 (3.6%) of 54,870 children for a rate of 4.3% per 30 person-days. Adjusted predictors of readmission included hepatobiliary procedures, increased wound class, operative duration, complications, and pLOS. The predictive model discriminated well in the derivation and validation cohorts (AUROC 0.710 and 0.701) with good calibration between observed and expected readmission events in both cohorts (p>.05). Unplanned readmission occurs less frequently in pediatric surgery than what is described in adults, calling into question its use as a quality indicator in this population. Factors that predict readmission including type of procedure, complications, and pLOS can be used to identify at-risk children and develop prevention strategies. III. Copyright © 2017 Elsevier Inc.

    Total laryngectomy is a standard procedure in head-and-neck surgery for the treatment of cancer patients. Recent clinical experiences have indicated a clinical benefit for patients undergoing transoral robot-assisted total laryngectomy (TORS-TL) with commercially available systems. Here, a new hybrid procedure for total laryngectomy is presented. TORS-TL was performed in human cadavers (n = 3) using a transoral-transcervical hybrid procedure. The transoral approach was performed with a robotic flexible robot-assisted surgical system (Flex®) and compatible flexible instruments. Transoral access and visualization of anatomical landmarks were studied in detail. Total laryngectomy is feasible with a combined transoral-transcervical approach using the flexible robot-assisted surgical system. Transoral visualization of all anatomical structures is sufficient. The flexible design of the robot is advantageous for transoral surgery of the laryngeal structures. Transoral robot assisted surgery has the potential to reduce morbidity, hospital time and fistula rates in a selected group of patients. Initial clinical studies and further development of supplemental tools are in progress. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

  16. Unintentionally retained foreign bodies after surgical procedures. Analysis of 4547 cases

    Directory of Open Access Journals (Sweden)

    Dário Vianna Birolini

    Full Text Available Objective: this study aims to explore the experience of Brazilian surgeons on Unintentionally Retained Foreign Bodies (RFB after surgical procedures. Methods: A questionnaire was sent to surgeons by electronic mail, between March and July 2012. The questions analyzed their experience with foreign bodies (FB, foreign bodies' types, clinical manifestations, diagnoses, risk factors and legal implications. Results: in the 2872 eligible questionnaires, 43% of the surgeons asserted that they had already left FB and 73% had removed FB in one or more occasions, totalizing 4547. Of these foreign bodies, 90% were textiles, 78% were discovered in the first year and 14% remained asymptomatic. Among doctors with less than five years after graduation, 36% had already left a FB. The most frequently surgical procedures mentioned were the elective (57% and routine (85% ones. Emergency (26%, lack of counting (25% and inadequate conditions of work contributed (12.5% to the occurrence. In 46% of the cases patients were alerted about the FB, and 26% of them sued the doctors or the institution. Conclusions: challenging medical situations, omission of security protocols and inadequate work conditions contributed to RFB. However, RFB occurs mostly in routine procedures such as cesarean or cholecystectomy, and at the beginning of the professional career, highlighting, particularly in poorest countries, the need for primary prevention. Textiles predominated causing clinical repercussions and they were diagnosed in the first postoperative months. Surgeons were sued in 11.3% of the RFB cases.

    Full Text Available INTRODUCTION: Rupture of the pectoralis major muscle appears to be increasing in athletes. However, the optimal treatment strategy has not yet been established. OBJECTIVES: To compare the isokinetic shoulder performance after surgical treatment to that after non-surgical treatment for pectoralis major muscle rupture. METHODS: We assessed 33 pectoralis major muscle ruptures (18 treated non-surgically and 15 treated surgically. Horizontal abduction and adduction as well as external and internal rotation at 60 and 120 degrees/s were tested in both upper limbs. Peak torque, total work, contralateral deficiency, and the peak torque agonist-to-antagonist ratio were measured. RESULTS: Contralateral muscular deficiency did not differ between the surgical and non-surgical treatment modalities. However, the surgical group presented twice the number of athletes with clinically acceptable contralateral deficiency (<20% for internal rotators compared to the non-surgical group. The peak torque ratio between the external and internal rotator muscles revealed a similar deficit of the external rotation in both groups and on both sides (surgical, 61.60% and 57.80% and non-surgical, 62.06% and 54.06%, for the dominant and non-dominant sides, respectively. The peak torque ratio revealed that the horizontal adduction muscles on the injured side showed similar weakness in both groups (surgical, 86.27%; non-surgical, 98.61%. CONCLUSIONS: This study included the largest single series of athletes reported to date for this type of injury. A comparative analysis of muscular strength and balance showed no differences between the treatment modalities for pectoralis major muscle rupture. However, the number of significant clinical deficiencies was lower in the surgical group than in the non-surgical group, and both treatment modalities require greater attention to the rehabilitation process, especially for the recovery of muscle strength and balance.

    The aim of this study was to describe the number and trend of surgical procedures for female genital fistula in England. An online search of Hospital Episode Statistics (HES) data was carried out. Data were available for the 4-year period from 2002-03 until 2005-06. The total number of surgical procedures carried out for female genital fistula steadily increased by 28.7% from 616 in 2002-03 to 793 in 2005-06. The number of surgical procedures performed for rectovaginal fistula exceeded the total number of surgical procedures carried out for vesicovaginal and urethrovaginal fistula in each year of the study period. This pattern needs to be monitored and investigated further.

    Full Text Available Background Healthcare Associated Infections constitute an important problem in Neonatal Units and invasive devices are frequently involved. However, studies on risk factors of newborns who undergo surgical procedures are scarce. Objective To identify risk factors for laboratory-confirmed bloodstream infection in neonates undergoing surgical procedures. Methods This case–control study was conducted from January 2008 to May 2011, in a referral center. Cases were of 21 newborns who underwent surgery and presented the first episode of laboratory-confirmed bloodstream infection. Control was 42 newborns who underwent surgical procedures without notification of laboratory-confirmed bloodstream infection in the study period. Information was obtained from the database of the Hospital Infection Control Committee Notification of infections and related clinical data of patients that routinely collected by trained professionals and follow the recommendations of Agência Nacional de Vigilância Sanitária and analyzed with Statistical Package for Social Sciences. Results During the study period, 1141 patients were admitted to Neonatal Unit and 582 Healthcare Associated Infections were reported (incidence-density of 25.75 Healthcare Associated Infections/patient-days. In the comparative analysis, a higher proportion of laboratory-confirmed bloodstream infection was observed in preterm infants undergoing surgery (p = 0.03 and use of non-invasive ventilation was a protective factor (p = 0.048. Statistically significant difference was also observed for mechanical ventilation duration (p = 0.004, duration of non-invasive ventilation (p = 0.04, and parenteral nutrition duration (p = 0.003. In multivariate analysis duration of parenteral nutrition remained significantly associated with laboratory-confirmed bloodstream infection (p = 0.041. Conclusions Shortening time on parenteral nutrition whenever possible and preference for non-invasive ventilation in neonates

    Surgical procedures involve unique elements related to patient safety. One must be aware of potential complications and safety issues within the practice of dermatologic surgery. Developing a high level of competence in skin surgery will address some safety issues, while implementing protocols and redundancies provides systems-based correction for other safety issues. We provide an in-depth review of patient safety in dermatologic surgery. In particular, we highlight the most common safety issues and methods for reducing error.

    OBJECTIVE Existing studies have shown a high overall rate of adverse events (AEs) following pediatric neurosurgical procedures. However, little is known regarding the morbidity of specific procedures or the association with risk factors to help guide quality improvement (QI) initiatives. The goal of this study was to describe the 30-day mortality and AE rates for pediatric neurosurgical procedures by using the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatrics (NSQIP-Peds) database platform. METHODS Data on 9996 pediatric neurosurgical patients were acquired from the 2012-2014 NSQIP-Peds participant user file. Neurosurgical cases were analyzed by the NSQIP-Peds targeted procedure categories, including craniotomy/craniectomy, defect repair, laminectomy, shunts, and implants. The primary outcome measure was 30-day mortality, with secondary outcomes including individual AEs, composite morbidity (all AEs excluding mortality and unplanned reoperation), surgical-site infection, and unplanned reoperation. Univariate analysis was performed between individual AEs and patient characteristics using Fischer's exact test. Associations between individual AEs and continuous variables (duration from admission to operation, work relative value unit, and operation time) were examined using the Student t-test. Patient characteristics and continuous variables associated with any AE by univariate analysis were used to develop category-specific multivariable models through backward stepwise logistic regression. RESULTS The authors analyzed 3383 craniotomy/craniectomy, 242 defect repair, 1811 laminectomy, and 4560 shunt and implant cases and found a composite overall morbidity of 30.2%, 38.8%, 10.2%, and 10.7%, respectively. Unplanned reoperation rates were highest for defect repair (29.8%). The mortality rate ranged from 0.1% to 1.2%. Preoperative ventilator dependence was a significant predictor of any AE for all procedure groups, whereas

    Nanotechnology involves the creation and use of materials and devices at the size scale of intracellular structures and molecules, and involves systems and constructs in the order of nanotechnology as applied to nanomedicine (e.g., biomimicry and pseudointelligence). Some applications of nanotechnology to ophthalmology are described (including treatment of oxidative stress; measurement of intraocular pressure; theragnostics; use of nanoparticles to treat choroidal new vessels, prevent scarring after glaucoma surgery, and treat retinal degenerative disease with gene therapy; prosthetics; and regenerative nanomedicine). Nanotechnology will revolutionize our approach to current therapeutic challenges (e.g., drug delivery, postoperative scarring) and will enable us to address currently unsolvable problems (e.g., sight-restoring therapy for patients with retinal degenerative disease). Obstacles to the incorporation of nanotechnology remain, such as safe manufacturing techniques and unintended biological consequences of nanomaterial use. These obstacles are not insurmountable, and revolutionary treatments for ophthalmic diseases are expected to result from this burgeoning field.

    It has been more than a year since ophthalmologists and scientists under Dr. Robin Ali's team at the Moorsfield Eye Hospital and the Institute of Ophthalmology, University College London, successfully treated patients with a severely blinding disease, Leber's congenital amaurosis (LCA) using gene therapy. This success does not look to be transient, and this achievement in gene replacement therapy clinical trial for LCA has instilled hope in numerous families with patients suffering from this and similar retinal degenerative diseases, for whom restoration of lost vision has remained a distant dream so far. The encouragement that this success has given is expected to also lead to start of clinical trials for other blinding ocular diseases for which gene therapy experiments at the laboratory and animal levels have been successful. This article reviews the various studies that have led to the understanding of gene therapy outcomes in human ocular diseases and attempts to provide a brief sketch of successful clinical trials.

    This review summarizes the most relevant articles from the field of neuro-ophthalmology published in the Journal of Neurology from January 2012 to July 2013. With the advent of video-oculography, several articles describe new applications for eye movement recordings as a diagnostic tool for a wide range of disorders. In myasthenia gravis, anti-Kv1.4 and anti-Lrp4 have been characterized as promising novel autoantibodies for the diagnosis of hitherto 'seronegative' myasthenia gravis. Several articles address new diagnostic and therapeutic approaches to neuromyelitis optica, which further sharpen its profile as a distinct entity. Additionally, 4-aminopyridine has become a standard therapeutic for patients with cerebellar downbeat nystagmus. Finally, revised diagnostic criteria have been proposed for chronic relapsing inflammatory optic neuropathy based on a careful literature review over the last decade.

    Preservatives are a legal requirement for eye drops in multidose containers. Moreover, they are necessary for stabilization and intraocular penetration for a number of ophthalmic preparations. Most preservatives act in a relatively unspecific manner as detergents or by oxidative mechanisms and thereby cause side effects at the ocular surface. They may also affect the lens, trabecular meshwork and the retina. Benzalkonium chloride is the most commonly used preservative in ophthalmology and is more toxic than other or newer preservatives, such as polyquaternium-1 (Polyquad), sodium perborate, oxychloro-complex (Purite®) and SofZia. Preservative-free topical medication is highly recommended for patients with ocular surface disease, frequent eye drop administration, proven allergy to preservatives and contact lens wear.

    Surgical site infections (SSI) are costly complications that may cause significant morbidity and increase the cost of care, particularly in colorectal surgery. Microbial sealants (MS) are a new class of wound barriers aimed at decreasing SSI; however, there is only evidence of benefit in clean class 1 procedures. Based on its success in class 1 procedures, we hypothesized that a microbial sealant could reduce the rate of SSI by half for clean-contaminated colorectal procedures (class 2). This was a single institution, multihospital, prospective, randomized study approved by the institutional review board. The primary objective was to determine the rate of SSI when microbial sealant (InteguSeal© Kimberly-Clark) is used compared to control (no microbial sealant). Data collected included: open versus laparoscopy, age, body mass index (BMI), diabetes and morbidity [American Society of Anesthesiologists (ASA) class], hospital readmission, reoperation and wound dehiscence. Enrolled subjects received the same preoperative mechanical bowel preparation with oral antibiotics, operative skin preparation (Chloraprep), Surgical Care Improvement Project guidelines implementation), and postoperative care glycemic control for diabetics. A total of 100 subjects were recruited over 15 months (MS-50; no MS-50). The overall incidence of SSI was 12 %, 14 % (7/50) in the MS versus 10 % (5/50) in the no MS group (p = 0.545). SSI incidence with and without microbial sealant was not significantly different in either the open or the laparoscopic subgroup. Laparoscopy decreased absolute risk of SSI by 16 %. Secondary data (age, BMI, diabetes, ASA) and tertiary data (readmission, reoperation, wound dehiscence) were positively correlated with SSI. Microbial sealant as employed in this study did not appear to offer any benefit in a class 2 (clean contaminated) operative procedure when perioperative care is standardized. The relative benefit of laparoscopy was also confirmed but unaffected by

    Aim: Ankyloglossia, commonly known as tongue-tie, is a congenital oral anomaly characterized by a short lingual frenulum that may contribute to feeding, speech and mechanical problems. The purpose of this study is to compare the advantages of laser vis-à-vis conventional frenectomy in both intra- and post-surgical phases. Methods: This study took into consideration two patients, who were respectively 9 and 10-year-old. The first one underwent a common surgical procedure. A Nd:Yap laser device with a micropulsed wavelength of 1340 nm and power of 8 watts was used for the second. The postsurgical discomfort and healing characteristics were evaluated. Results: The results indicated that the Nd:Yap laser has the following advantages when compared to the conventional frenectomy: 1) soft tissue cutting was efficient, with no bleeding, giving a clear operative field; 2) there was no need to use sutures; 3) the surgery was less time-consuming; 4) there was no postsurgical infection and no need for analgesics or antibiotics; 5) wound contraction and scarring were decreased or eliminated; 6) despite the initial slowness of the healing process, the complete and final recovery was faster. Conclusion: Considering the above elements, it is possible to assert that the laser frenectomy has a series of unquestionable advantages if compared to the conventional surgical technique.

    Anxiety and pain are two significant problems experienced by children undergoing elective surgical procedures, which may lead to suboptimal postoperative outcomes. Previous studies have shown a correlation between perioperative anxiety and pain in children. This review aimed to present the best available evidence on the correlation between perioperative anxiety and pain in children undergoing elective surgical procedures, and to determine the relationship between children's demographics, their anxiety and pain level in the perioperative period. Participants were children aged between five to 18 years old who were scheduled for an elective surgical procedure in the hospital setting.No specific intervention was of interest. So long as the primary studies examined correlation of children's anxiety and pain in the perioperative period, they were considered for inclusion.This review focused on children's preoperative level of anxiety; children's postoperative level of anxiety; children's postoperative pain intensity; and/or children's postoperative behavioural changes.This review included quantitative research studies, such as randomised-controlled trials, cohort studies, and descriptive studies which addressed the correlation between perioperative anxiety and perioperative pain in children undergoing elective surgical procedures. A three-step search strategy was utilised in this review. The following databases were searched for articles published in English from the inception date of databases to December 2010: CINAHL, PubMed, Scopus, PsycINFO, Mednar, Trip Database, ProQuest Dissertations and Theses, Scirus ETD and Web of Science. Papers selected for retrieval were assessed independently by two reviewers for methodological quality prior to inclusion in the review using standardised critical appraisal tools from Joanna Briggs Institute. There were no disagreements between the two reviewers, so the third reviewer was not required. Data were extracted using the

    Postoperative ileus is a major complication of abdominal surgical procedures To evaluate the incidence of ileus and gastrointestinal morbidity in patients who received immediate postoperative feeding and bowel stimulation after undergoing major gynecologic surgical procedures. During a 5-year period, the authors tracked demographic, surgical outcome, and follow-up information for 707 patients who underwent major gynecologic operations. All patients received the same postoperative orders, including immediate feeding of a diet of choice and bowel stimulation with 30 mL of magnesium hydroxide (milk of magnesia) twice daily until bowel movements occurred. Of 707 patients, 6 (<1%) had postoperative ileus. No patients experienced postoperative bowel obstruction and 2 patients (0.3%) had postoperative intestinal leak. No serious adverse effects associated with bowel stimulation were reported. Immediate postoperative feeding and bowel stimulation is a safe and effective approach to preventing ileus in patients who undergo major gynecologic surgical procedures.

    We describe a combination of 3 surgical procedures for implant placement in the posterior maxilla with insufficient bone quantity and quality. In these situations, we have performed 3 minimally invasive, safe, and reliable surgical procedures: buccal bone graft with bone harvested from the mandibular molar region, submucous vestibuloplasty using artificial dermis, and bone-added osteotome sinus floor elevation under endoscopic control. These modified procedures can be performed in the office setting under outpatient local anesthesia and may minimize patient discomfort and reduce postoperative complications.

    Regional surgical quality improvement consortiums are becoming more common. Herein we have reported the effectiveness of a statewide consortium focusing on open vascular operative procedures. The statewide Michigan Surgical Quality Consortium was established in 2005 with 16 hospitals that report cases of vascular open operative intervention, in a sampling manner consistent with the private sector National Surgical Quality Improvement Program. Data are abstracted by onsite trained nurses using defined and validated pre-, peri-, and postoperative variables with 30-day follow-up. Outpatient and emergent cases were excluded. We compared outcomes over the course of the consortium (era I, April 2005-March 2007; era II, April 2007-March 2008) via univariate and multivariate techniques. Era I (n = 2,453) and era II (n = 3,409) cases were similar in age (mean, 68 years), gender (61% male), relative value units (mean, 21), and distribution of Current Procedural Terminology codes. Duration of stay and operative time decreased by 15% and 11%, respectively, when comparing era I with era II (P cardiac or renal, complications. When evaluating both eras, modifiable variables (able to be altered by the surgeon) for morbidity included increased length of operation (odds ratio [OR], 1.004; 95% confidence interval [CI], 1.003-1.005; P < .0001), hypertension (OR, 1.46; 95% CI, 1.03-2.1; P = .03), and blood transfusion (OR, 2.8; 95% CI, 2.04-3.88; P < .0001). However, anemic patients (11%; hematocrit <30) who were transfused were less likely to suffer morbidity (OR, 56; 95% CI, 0.47-0.67; P < .0001) than those transfused who were not anemic. The absolute 2% reduction in complications led to a $172 cost savings for the payers per patient in era II compared with era I. A statewide quality-of-care consortium with timely feedback of data was associated with decreased morbidity over a relatively short follow-up period in vascular patients.

    Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgical procedures to prevent transient urinary tract obstruction and postoperative flank pain from ureteral edema and blood clots. Several restrictive conditions that make this procedure difficult and time consuming, however, include the coiled distal ends of the flexible Double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a Double-J stent insertion method using the new J-tube technique. Between July 2011 and May 2013, Double-J stents were inserted using the J-tube technique in 33 patients who underwent a laparoscopic UUT surgical procedure by a single surgeon. The mean stent placement time was 4.8±2.7 minutes, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for Double-J stent insertion during laparoscopic surgical procedures.

    We sought to evaluate the incidence, epidemiology, and factors associated with surgical site infections (SSIs) after lower extremity revascularization procedures involving groin incisions and determine outcomes based on SSI status. This is a single-institution, retrospective cohort study of 106 patients who underwent lower extremity revascularization procedures involving femoral artery exposure through a groin incision at a tertiary referral hospital. The primary outcome was occurrence of SSI at the groin wound. The duration of hospital stay, reoperation within 30 days, discharge disposition, and 30-day mortality were also evaluated. Independent variables included patient demographics and operative variables (i.e., procedure type, transfusion requirements, preoperative antibiotics, intraoperative vasopressors, and operative duration). Statistical analysis included chi-squared tests, t-tests, and multivariable regression analysis. Of the 106 patients who underwent a lower extremity revascularization procedure with a groin incision for femoral artery exposure, 62% were male, and the mean age was 62 years. Comorbidities included hypertension (93%), dyslipidemia (65%), statin use (63%), active smoker (50%), diabetes (24%), and chronic obstructive pulmonary disease (23%). All patients received preoperative antibiotics, 50% required intraoperative pressors, 21% received a blood transfusion, and the mean operative time was 296 min. The overall duration of stay was 10.7 days, the 30-day reoperation rate was 18%, and the 30-day mortality rate was 12%. Overall, 22% developed a seroma or hematoma, and 31% developed a SSI. Patients who developed an SSI compared with those who did not were more likely to have a postoperative seroma or hematoma (55% vs 5%) and to receive a blood transfusion (33% vs 15%), but less likely to be treated with a statin (47% vs 69%) or carry a diagnosis of dyslipidemia (50% vs 72%), respectively, all P surgical site complications after lower

    The benefits of ceramics in biomedical applications have been universally appreciated as they exhibit an extraordinarily broad set of physico-chemical, mechanical and biological properties which can be properly tailored by acting on their composition, porosity and surface texture to increase their versatility and suitability for targeted healthcare applications. Bioceramics have traditionally been used for the repair of hard tissues, such as bone and teeth, mainly due to their suitable strength for load-bearing applications, wear resistance (especially alumina, zirconia and composites thereof) and, in some cases, bone-bonding ability (calcium orthophosphates and bioactive glasses). Bioceramics have been also applied in other medical areas, like ophthalmic surgery; although their use in such a context has been scientifically documented since the late 1700s, the potential and importance of ceramic ocular implants still seem to be underestimated and an exhaustive, critical assessment is currently lacking in the relevant literature. The present review aims to fill this gap by giving a comprehensive picture of the ceramic-based materials and implants that are currently used in ophthalmology and pointing out the strengths and weaknesses of the existing devices. A prospect for future research is also provided, highlighting the potential of new, smart bioceramics able to carry specific added values which could have a significant impact on the treatment of ocular diseases.

    Full Text Available It has been more than a year since ophthalmologists and scientists under Dr. Robin Ali′s team at the Moorsfield Eye Hospital and the Institute of Ophthalmology, University College London, successfully treated patients with a severely blinding disease, Leber′s congenital amaurosis (LCA using gene therapy. This success does not look to be transient, and this achievement in gene replacement therapy clinical trial for LCA has instilled hope in numerous families with patients suffering from this and similar retinal degenerative diseases, for whom restoration of lost vision has remained a distant dream so far. The encouragement that this success has given is expected to also lead to start of clinical trials for other blinding ocular diseases for which gene therapy experiments at the laboratory and animal levels have been successful. This article reviews the various studies that have led to the understanding of gene therapy outcomes in human ocular diseases and attempts to provide a brief sketch of successful clinical trials.

    Although consecutive surgical hand disinfections is common clinical practice, the effect on the bacterial density on hands has not been studied for all commonly used hand rubs. We studied the effect of 2 consecutive applications of hand rubs on resident bacterial hand flora. A propanol-based hand rub (PBHR; Sterillium) and the reference alcohol (60% n-propanol) were tested in a Latin-square design according to EN 12791. The first application of the PBHR was always for 1.5 minutes; the second application was for 1.5, 1, or 0.5 minutes. The reference alcohol was always applied for 3 minutes. Pre-values and post-values were obtained in accordance with EN 12791. The first reference disinfection reduced the bacterial density by 2.87 log(10) (immediate efficacy) and 2.27 log(10) (after 3 hours). The PBHR yielded a similar reduction. Immediately after the second reference disinfection, bacterial density was reduced by 0.45 log(10). Application of the PBHR yielded greater reductions of 0.71 log(10) (after 0.5 minute), 0.79 log(10) (after 1 minute), and 1.12 log(10) (after 1.5 minutes). The difference between all treatments was not significant (P = .089; Friedman test). After 3 hours, bacterial density was further decreased by 1.11 log(10) (reference disinfection), 1.89 log(10) (PBHR, 1 minute), 1.67 log(10) (PBHR, 1.5 minutes), and 1.08 log(10) (PBHR, 0.5 minute). The difference between all treatments was significant (P = .005), but none of the short treatments with the PBHR was significantly less effective than the reference treatment (P > .05; Wilcoxon-Wilcox test). Overall, a simple 1.5-minute application of a well-formulated PBHR for surgical hand disinfection keeps the bacterial density as low as possible ("irreducible minimum") even in 2 consecutive surgical procedures of 3 hours.

    Postoperative nausea and vomiting (PONV) is a common source of patient discomfort and decreased satisfaction. Aromatherapy has been identified as a complementary modality for the prevention and management of PONV. The purpose of this study was to assess the effect of aromatherapy on the severity of postoperative nausea (PON) in women undergoing surgical procedures in the postanesthesia care unit. Women complaining of PON received traditional antiemetics, inhalation of peppermint oil, or saline vapor. A visual analog scale was used to rate nausea at the first complaint; at 5 minutes after intervention; and, if nausea persisted, at 10 minutes after intervention. At both 5 and 10 minutes, statistical analysis showed no significant differences between intervention and nausea rating. Obtaining eligible subjects was challenging. Although many women consented, most received intraoperative antiemetics and did not report nausea postoperatively.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    Obesity has reached an overwhelming high in the United States as well as other developing countries around the world. Alone, approximately 60 million Americans are characterized as obese, and 10 million of them are considered morbidly obese. Many have tried and failed not only to lose the excess weight through fad diets, medically supervised diets, exercise programs, and athletic club memberships, but also to maintain a healthy weight. As a result, weight gain and loss has become a way of life, an unhealthy way of life. This often results in a weight gain of a greater number of pounds than where they started. As a result, many patients and their physicians are looking to weight loss surgery as a permanent solution to the problem of yo-yo dieting. Along with the surgical alterations to the digestive system, nutrition counseling with portion control and regular exercise are part of a comprehensive program for successful long-term weight maintenance. It is the intent of this article to provide the reader with the basic understanding of the normal anatomy of the digestive tract. Then, each surgical procedure will be discussed, enabling the reader to visualize the changes in the digestion and absorption of food. It is these changes in absorption of vitamins and minerals, fats and carbohydrates, and proteins that lead to the various medical complications seen in patients after bariatric surgery.

  5. Environmental Impacts of Surgical Procedures: Life Cycle Assessment of Hysterectomy in the United States

    Science.gov (United States)

    2015-01-01

    The healthcare sector is a driver of economic growth in the U.S., with spending on healthcare in 2012 reaching $2.8 trillion, or 17% of the U.S. gross domestic product, but it is also a significant source of emissions that adversely impact environmental and public health. The current state of the healthcare industry offers significant opportunities for environmental efficiency improvements, potentially leading to reductions in costs, resource use, and waste without compromising patient care. However, limited research exists that can provide quantitative, sustainable solutions. The operating room is the most resource-intensive area of a hospital, and surgery is therefore an important focal point to understand healthcare-related emissions. Hybrid life cycle assessment (LCA) was used to quantify environmental emissions from four different surgical approaches (abdominal, vaginal, laparoscopic, and robotic) used in the second most common major procedure for women in the U.S., the hysterectomy. Data were collected from 62 cases of hysterectomy. Life cycle assessment results show that major sources of environmental emissions include the production of disposable materials and single-use surgical devices, energy used for heating, ventilation, and air conditioning, and anesthetic gases. By scientifically evaluating emissions, the healthcare industry can strategically optimize its transition to a more sustainable system. PMID:25517602

    This study was aimed at investigating the correlation between intraoperative blood loss and operation-related factors in the treatment of bimaxillary protrusion with four different procedures. Ninety-four patients were separated into the following four surgical groups: group 1: anterior subapical osteotomy of the maxilla (ASO Mx) + bilateral parasymphyseal osteotomy of the mandible (BPsO Md) + genioplasty (GeP); group 2: ASO Mx + BPsO Md; group 3: ASO Mx + ASO Md + GeP; and group 4: ASO Mx + ASO Md. Patient- and operation-related factors (age, intraoperative blood loss, operation time, and preoperative and postoperative blood parameters) were compared among the four groups. The mean operation time and intraoperative blood loss were 438.7 minutes and 369.9 mL in group 1; 432.5 minutes and 356.5 mL in group 2; 393.3 minutes and 387.3 mL in group 3; and 353.5 minutes and 289.5 mL in group 4. Intergroup differences in intraoperative blood loss were not significant. A significant correlation between intraoperative blood loss and operation time was found in group 4 but not in the other groups. No significant differences in blood loss were found among the four different surgical procedures in the treatment of bimaxillary protrusion. Copyright © 2016 Elsevier Inc. All rights reserved.

    Orthotopic liver transplantation (OLT) in rats using a whole or partial graft is an indispensable experimental model for transplantation research, such as studies on graft preservation and ischemia-reperfusion injury, immunological responses, hemodynamics, and small-for-size syndrome. The rat OLT is among the most difficult animal models in experimental surgery and demands advanced microsurgical skills that take a long time to learn. Consequently, the use of this model has been limited. Since the reliability and reproducibility of results are key components of the experiments in which such complex animal models are used, it is essential for surgeons who are involved in rat OLT to be trained in well-standardized and sophisticated procedures for this model. While various techniques and modifications of OLT in rats have been reported since the first model was described by Lee et al. in 1973, the elimination of the hepatic arterial reconstruction and the introduction of the cuff anastomosis technique by Kamada et al. were a major advancement in this model, because they simplified the reconstruction procedures to a great degree. In the model by Kamada et al., the hepatic rearterialization was also eliminated. Since rats could survive without hepatic arterial flow after liver transplantation, there was considerable controversy over the value of hepatic arterialization. However, the physiological superiority of the arterialized model has been increasingly acknowledged, especially in terms of preserving the bile duct system and the liver integrity. In this article, we present detailed surgical procedures for a rat model of OLT with hepatic arterial reconstruction using a 50% partial graft after ex vivo liver resection. The reconstruction procedures for each vessel and the bile duct are performed by the following methods: a 7-0 polypropylene continuous suture for the supra- and infrahepatic vena cava; a cuff technique for the portal vein; and a stent technique for the

    Professional basketball players have a high incidence of injuries requiring surgical intervention. However, no studies in the current literature have compared postoperative performance outcomes among common injuries to determine high- and low-risk procedures to these athletes' careers. To compare return-to-play (RTP) rates and performance-based outcomes after different orthopaedic procedures in National Basketball Association (NBA) players and to determine which surgeries are associated with the worst postoperative change in performance. Cohort study; Level of evidence, 3. Athletes in the NBA undergoing anterior cruciate ligament reconstruction, Achilles tendon repair, lumbar discectomy, microfracture, meniscus surgery, hand/wrist or foot fracture fixation, and shoulder stabilization were identified through team injury reports and archives on public record. The RTP rate, games played per season, and player efficiency rating (PER) were determined before and after surgery. Statistical analysis was used to compare the change between pre- and postsurgical performance among the different injuries. A total of 348 players were included. The RTP rates were highest in patients with hand/wrist fractures (98.1%; mean age, 27.0 years) and lowest for those with Achilles tears (70.8%; mean age, 28.4 years) (P = .005). Age ≥30 years (odds ratio [OR], 3.85; 95% CI, 1.24-11.91) and body mass index ≥27 kg/m(2) (OR, 3.46; 95% CI, 1.05-11.40) were predictors of not returning to play. Players undergoing Achilles tendon repair and arthroscopic knee surgery had a significantly greater decline in postoperative performance outcomes at the 1- and 3-year time points and had shorter career lengths compared with the other procedures. NBA players undergoing Achilles tendon rupture repair or arthroscopic knee surgery had significantly worse performance postoperatively compared with other orthopaedic procedures. © 2016 The Author(s).

    Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p cardiac surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

  11. Perspective: authentic patient perspectives in simulations for procedural and surgical skills.

    Science.gov (United States)

    Nestel, Debra; Kneebone, Roger

    2010-05-01

    In this article, the authors consider the role of the patient in simulation-based training and assessment of clinical procedural skills. In recent years, there has been a progressive shift of emphasis from teacher-centered to student-centered education, resulting in a redefinition of approaches to medical education. Traditional models of transmission of information from an expert to a novice have been supplanted by a more student-centered approach. However, medical education is not a matter for teacher and student alone. At the center is always the patient, around whom everything must ultimately rotate. A further shift is occurring. The patient is becoming the focal point of medical teaching and learning. It is argued that this shift is necessary and that simulation in its widest sense can be used to support this process. However, sensitivity to what we are simulating is essential, especially when simulations purport to address patient perspectives. The essay first reviews the history of medical education "centeredness," then outlines ways in which real and simulated patients are currently involved in medical education. Patient-focused simulation (PFS) is described as a means of offering patients' perspectives during the acquisition of clinical procedural and surgical skills. The authors draw on their experiences of developing PFS and preliminary work to "authenticate" simulations from patient perspectives. The essay concludes with speculation on the value of a "complementarity" model that acknowledges the authentic and equal perspectives of patients, students, clinicians, and teachers.

    Monitoring surgical site infection (SSI) performed during hospitalization can underestimate its rates due to the shortening in hospital stay. The aim of this study was to determine the actual rates of SSI using a post-discharge monitoring system. All patients who underwent herniorraphy or mastectomy in the Hospital Universitario Ramón y Cajal from 1 January 2011 to 31 December 2011 were included. SSI data were collected prospectively according to the continuous quality improvement indicators (Indicadores Clinicos de Mejora Continua de la Calidad [INCLIMECC]) monitoring system. Post-discharge follow-up was conducted by telephone survey. A total of 409patients were included in the study, of whom 299 underwent a herniorraphy procedure, and 110 underwent a mastectomy procedure. For herniorrhaphy, the SSI rate increased from 6.02% to 7.6% (the post-discharge survey detected 21.7% of SSI). For mastectomy, the SSI rate increased from 1.8% to 3.6% (the post-discharge survey detected 50% of SSI). Post-discharge monitoring showed an increased detection of SSI incidence. Post-discharge monitoring is useful to analyze the real trend of SSI, and evaluate improvement actions. Post-discharge follow-up methods need to standardised.

    as an intermediate therapeutical option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29% differ extremely from success rates reported in case series (between 56% and 92%. The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion: Aside from low methodological study quality three conceptual problems complicate the interpretation of results. 1. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results

    option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29%) differ extremely from success rates reported in case series (between 56% and 92%). The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion Aside from low methodological study quality three conceptual problems complicate the interpretation of results. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results. However, diversity is noted not only for

    Background One of the main aims of orthodontists is to reduce the treatment time as much as possible, particularly in view of the rise in demand for orthodontic treatment among adult patients. The objective of this systematic review was to examine the effectiveness of corticotomy as a surgical procedure that accelerates orthodontic tooth movement, together with its possible adverse effects. Material and Methods A systematic review of articles in 4 databases, Pubmed, Cochrane, Scopus and Embase, complemented by a manual search, identified 772 articles. The duplicates were eliminated and a critical reading of titles and abstracts led to the rejection of articles that did not meet the objectives of the review, leaving 69. After reading the full text of these articles, 49 were excluded because they did not meet the inclusion criteria. On applying the CONSORT criteria as a quality filter, a further 4 were eliminated due to low quality. Finally, 16 articles (4 systematic reviews and 12 controlled trials) were reviewed. Results All the studies agree that corticotomy prior to orthodontic treatment accelerates dental movement, reducing the treatment time. With regard to side-effects, no periodontal damage was found, although this was only studied in the short term. Conclusions The evidence regarding the results of corticotomy is limited, given the small number of quality clinical studies available. Before this procedure is included as a routine practice in dental surgeries, studies of higher methodological quality are required, studying a greater number of individuals and examining the possible long-term adverse effects and the cost/benefit of the procedure.

  16. Non-photorealistic rendering of virtual implant models for computer-assisted fluoroscopy-based surgical procedures

    Surgical navigation systems visualize the positions and orientations of surgical instruments and implants as graphical overlays onto a medical image of the operated anatomy on a computer monitor. The orthopaedic surgical navigation systems could be categorized according to the image modalities that are used for the visualization of surgical action. In the so-called CT-based systems or 'surgeon-defined anatomy' based systems, where a 3D volume or surface representation of the operated anatomy could be constructed from the preoperatively acquired tomographic data or through intraoperatively digitized anatomy landmarks, a photorealistic rendering of the surgical action has been identified to greatly improve usability of these navigation systems. However, this may not hold true when the virtual representation of surgical instruments and implants is superimposed onto 2D projection images in a fluoroscopy-based navigation system due to the so-called image occlusion problem. Image occlusion occurs when the field of view of the fluoroscopic image is occupied by the virtual representation of surgical implants or instruments. In these situations, the surgeon may miss part of the image details, even if transparency and/or wire-frame rendering is used. In this paper, we propose to use non-photorealistic rendering to overcome this difficulty. Laboratory testing results on foamed plastic bones during various computer-assisted fluoroscopybased surgical procedures including total hip arthroplasty and long bone fracture reduction and osteosynthesis are shown.

    The arthroscopic Latarjet procedure has provided reliable results in the treatment of anterior shoulder instability. However, this procedure remains technically challenging and is related to several complications. The morphology of the coracoid and the glenoid are inconsistent. Inadequate coracoid and glenoid preparing may lead to mismatching between their surfaces. Inadequate screws lengthening and orientation are a major concern. Too long screws can lead to suprascapular nerve injuries or hardware irritation, whereas too short screws can lead to nonunions, fibrous unions or migration of the bone block. The purpose of the study was to investigate the application of virtual surgical planning and digital technology in preoperative assessment and planning of the Latarjet procedure. Twelve patients planned for an arthroscopic Latarjet had a CT scan evaluation with multi-two-dimensional reconstruction performed before surgery. Interobserver and intraobserver reliability were evaluated. The shape of the anterior rim of the glenoid and the undersurface of the coracoid were classified. Coracoid height was measured, respectively, at 5 mm (C1) and 10 mm (C2) from the tip of the coracoid process, corresponding to the drilling zone. Measurements of the glenoid width were then taken in the axial view at 25 % (G1) and 50 % (G2) of the glenoid height with various α angles (5°, 10°, 15°, 20°, 25°, 30°) 7 mm from the anterior glenoid rim. Shapes of the undersurface of the coracoid and the anterior rim of the glenoid were noted during the surgical procedure. Post-operative measurements included the α angle. Concerning coracoid height measurements, there was an almost perfect to substantial intra- and inter-reliability, with values ranging from ICC = 0.75-0.97. For the shape of the coracoid, concordances were, respectively, perfect (ICC = 1) and almost perfect (0.87 [0.33; 1]) for the intra- and interobserver reliabilities. Concerning the glenoid, concordance was

    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

    The First Surgical Clinic of the First Medical Faculty of Charles University and General Faculty Hospital in Prague made operations of the pancreas ever since 1971. In the work sooner or later all approaches to surgical treatment pancreatitis were reflected. The authors present a brief review of results and their own experience since 1994 when duodenum-sparing operations were introduced. Indications for surgical treatment were based on the diagnosis by US, CT and ERCP, in exceptional case MR, after evaluation by a pancreatologist, roentgenologist and surgeon. The group of patients with chronic pancreatitis was extended by 21 patients from a group operated because of preoperative suspicion of a malignant pancreatic tumour not confirmed during and after surgery. In those Whipple's operation was preformed. The same operation was performed in three patients with chronic pancreatitis with serious changes in the area of the head of the pancreas. In 123 patients a drainage and duodenum sparing operation was preformed, of these in 57 according to Beger, 19 according to Frey, 37 Partington-Rochelle's procedure. The authors record two sepsis postoperative complications after the classical Beger operation and the hospital stay was on average by five days shorter as compared with the classical method of Whipple. When evaluating postoperative complaints and problems (pain, malnutrition, physical constitution and social position) the authors recorded equally favourable results as after non-complicated duodenopancreatectomy. They varied, depending on the patients co-operation round 84-87% while authors consider Beger's operation logical because of the removal of the main tissue mass of the head of the pancreas, responsible for pain, complications caused by fibrosis in the area round the bile duct and duodenum, responsible for the deteriation of the compartment syndrome in the left half of the gland. Its result is destruction of the remainder of exocrine and endocrine tissue. Of

    Full Text Available Introduction: The healing process after surgery is a challenging issue for surgeons. Various materials and techniques have been developed to facilitate this process and reduce its period. Fibrin adhesives are often used in cardiothoracic and vascular surgery to seal diffuse microvascular bleeding and in general and plastic surgery to seal wound borders. This Case report and literature review will introduce the various usages of platelet-rich fibrin in different surgical procedures and the method of producing the matrix. Case Report: A 24-year old man with periorbital skin avulsion treated with PRF membrane has been reported and discussed in this paper.  Conclusion: Platelet-rich fibrin is a natural autologous fibrin matrix, which can be produced with a simple blood sample and a table centrifuge. The material has been used in a wide range of surgical procedures to shorten the healing period and reduce post-surgical complications.

    Although orthopedics and ophthalmology seem to be two different medical specialties, numerous studies that have been conducted in the past 35 years have shown a tight connection between several ocular pathologies and an increased risk of hip fractures due to falling. This article aims to review the ocular pathologies that have been proven to be associated with an increased risk of falling, to integrate the results of several studies showing a direct relationship between ocular pathologies and an increased risk of falling and finally to suggest ways in which the incidence of traumatic orthopedic injuries can be reduced by applying ophthalmologic principles.

    Purpose Using a network meta-analysis approach, our study aims to develop a ranking of the six surgical procedures, that is, Plate, titanium elastic nail (TEN), tension band wire (TBW), hook plate (HP), reconstruction plate (RP) and Knowles pin, by comparing the post-surgery constant shoulder scores in patients with clavicular fracture (CF). Methods A comprehensive search of electronic scientific literature databases was performed to retrieve publications investigating surgical procedures in CF, with the stringent eligible criteria, and clinical experimental studies of high quality and relevance to our area of interest were selected for network meta-analysis. Statistical analyses were conducted using Stata 12.0. Results A total of 19 studies met our inclusion criteria were eventually enrolled into our network meta-analysis, representing 1164 patients who had undergone surgical procedures for CF (TEN group = 240; Plate group = 164; TBW group  =  180; RP group  =  168; HP group  =  245; Knowles pin group  =  167). The network meta-analysis results revealed that RP significantly improved constant shoulder score in patients with CF when compared with TEN, and the post-operative constant shoulder scores in patients with CF after Plate, TBW, HP, Knowles pin and TEN were similar with no statistically significant differences. The treatment relative ranking of predictive probabilities of constant shoulder scores in patients with CF after surgery revealed the surface under the cumulative ranking curves (SUCRA) value is the highest in RP. Conclusion The current network meta-analysis suggests that RP may be the optimum surgical treatment among six inventions for patients with CF, and it can improve the shoulder score of patients with CF. Implications for Rehabilitation RP improves shoulder joint function after surgical procedure. RP achieves stability with minimal complications after surgery. RP may be the optimum surgical treatment for

    Full Text Available Background:  Elbow surgery is shared by several subspecialties. We were curious about the most common elbow surgeries and their corresponding diagnoses in the United States.   Methods:  We used the National Hospital Discharge Survey (NHDS and the National Survey of Ambulatory Surgery (NSAS data gathered in 2006-databases that together provide an estimate of all inpatient and ambulatory surgical care in the US.  Results:  An estimated 150,000 elbow surgeries were performed in the US in 2006, 75% in an outpatient setting. The most frequent diagnosis treated operative was enthesopathy (e.g. lateral epicondylitis and it was treated with several different procedures. More than three quarters of all elbow surgeries treated enthesopathy, cubital tunnel syndrome, or fracture (radial head in particular. Arthroscopy and arthroplasty accounted for less than 10% of all elbow surgeries.  Conclusions:  Elbow surgery in the United States primarily addresses enthesopathies such as tennis elbow, cubital tunnel syndrome, and trauma. It is notable that some of the most common elbow surgeries (those that address enthesopathy and radial head fracture are some of the most variably utilized and debated.

    Full Text Available Preoperative routine tests are commonly used to evaluate patients who will have planned elective surgical procedure. In this study, we aimed to identify the preoperative tests required for ASA I-II patients, over 40 years old, who will undergo elective minor and moderate surgeries. Totally 140 patients were included in the study. They were separated into 2 groups equally [Group I (40-59 years and Group II (≥60 years] according to their ages. The patients’ preoperative tests; including chest radiography, electrocardiography, hemoglobin, white blood cell, platelets, glucose, sodium, potassium, aspartate transaminase, alanine transaminase, ürea and creatinine were evaluated together with history and physical examination. After routine monitoring, balance anaesthesia was performed. The patients were followed during the peroperative and postoperative 24 hours for any problems occurred. In Group I; excluding ürea in both male and female patients and haemoglobin in only female patients; preoperative tests had no effect on the management of the asymptomatic patients. In Group II; electrocardiography, chest radiography, ürea, glucose and hemoglobin tests effected the management of the patients in the preoperative and postoperative period. In conclusion, preoperative tests could be ordered according to history and physical examination of the patients.

  14. Bilateral symmetry in vision and influence of ocular surgical procedures on binocular vision: A topical review.

    2016-01-01

    We analyze the role of bilateral symmetry in enhancing binocular visual ability in human eyes, and further explore how efficiently bilateral symmetry is preserved in different ocular surgical procedures. The inclusion criterion for this review was strict relevance to the clinical questions under research. Enantiomorphism has been reported in lower order aberrations, higher order aberrations and cone directionality. When contrast differs in the two eyes, binocular acuity is better than monocular acuity of the eye that receives higher contrast. Anisometropia has an uncommon occurrence in large populations. Anisometropia seen in infancy and childhood is transitory and of little consequence for the visual acuity. Binocular summation of contrast signals declines with age, independent of inter-ocular differences. The symmetric associations between the right and left eye could be explained by the symmetry in pupil offset and visual axis which is always nasal in both eyes. Binocular summation mitigates poor visual performance under low luminance conditions and strong inter-ocular disparity detrimentally affects binocular summation. Considerable symmetry of response exists in fellow eyes of patients undergoing myopic PRK and LASIK, however the method to determine whether or not symmetry is maintained consist of comparing individual terms in a variety of ad hoc ways both before and after the refractive surgery, ignoring the fact that retinal image quality for any individual is based on the sum of all terms. The analysis of bilateral symmetry should be related to the patients' binocular vision status. The role of aberrations in monocular and binocular vision needs further investigation.

    Surgical site infections (SSIs) are a threat to patient safety. However, there are not available data on SSI rates stratified by surgical procedure (SP) in Peru. From January 2005 to December 2010, a cohort prospective surveillance study on SSIs was conducted by the International Nosocomial Infection Control Consortium (INICC) in four hospitals in three cities of Peru. Data were recorded from hospitalized patients using the U.S. Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) methods and definitions for SSI. Surgical procedures (SPs) were classified into 4 types, according to ICD-9 criteria. We recorded 352 SSIs, associated to 13,904 SPs (2.5%; CI, 2.3-2.8) SSI rates per type of SP were the following for this study's Peruvian hospitals, compared with rates of the INICC and CDC-NHSN reports, respectively: 2.9% for appendix surgery (vs. 2.9% vs. 1.4%); 2.8% for gallbladder surgery (vs. 2.5% vs. 0.6%); 2.2% for cesarean section (vs. 0.7% vs. 1.8%); 2.8% for vaginal hysterectomy (vs. 2.0% vs. 0.9%). Our SSIs rates were higher in all of the four analyzed types of SPs compared with CDC-NHSN, whereas compared with INICC, most rates were similar. This study represents an important advance in the knowledge of SSI epidemiology in Peru that will allow us to introduce targeted interventions.

    Milić, Dragan J; Pejić, Miljko A

    2003-01-01

    Hernia repair is one of the most common surgical procedures performed in the United States, with 700,000 operations performed each year. Improvements in surgical technique, together with the development of new prosthetic materials and a better understanding of how to use them, have significantly improved outcomes for many patients. These improvements have occurred most notably in centers specializing in hernia surgery, with some institutions reporting failure rates of less than 1%. In contrast, failure rates for general surgeons, who perform most hernia repairs, remain significantly higher. This has important socioeconomic implications, adding an estimated $28 billion or more to the cost of treating the condition, based on calculations utilizing conservative estimates of failure rates and the average cost of a hernia repair. Success of groin hernia repair is measured primarily by the permanence of the operation, fewest complications, minimal costs, and earliest return to normal activities. This success depends largely on the surgeon's understanding of the anatomy and physiology of the surgical area as well as a knowledge of how to use most effectively the currently available techniques and materials. The most important advance in hernia surgery has been the development of tension-free repairs. In 1958, Usher described a hernia repair using Marlex mesh. The benefit of that repair he described as being "tension-eliminating" or what we now call "tension-free". Usher opened the posterior wall and sutured a swatch of Marlex mesh to the undersurface of the medial margin of the defect and to the shelving edge of the inguinal ligament. He created tails from the mesh that encircled the spermatic cord and secured them to the inguinal ligament. Every type of tension-free repair requires a mesh, whether it is done through an open anterior, open posterior, or laparoscopic route. The most common prosthetic open repairs done today are the Lichtenstein onlay patch repair, the Per

    Water jet dissection represents a promising technique for precise brain tissue dissection with preservation of blood vessels. In the past, the water jet dissector has been used for various pathologies. A detailed report of the surgical technique is lacking. The authors present their results after 208 procedures with a special focus on surgical technique, intraoperative suitability, advantages, and disadvantages. Between March 1997 and April 2009, 208 patients with various intracranial neurosurgical pathologies were operated on with the water jet dissector. Handling of the device and its usefulness and extent of application were assessed. The pressures encountered, potential risks, and complications were documented. The patients were followed 1 to 24 months postoperatively. A detailed presentation of the surgical technique is given. Differences and limitations of the water jet dissection device in the various pathologies were evaluated. The water jet dissector was intensively used in 127 procedures (61.1%), intermittently used in 56 procedures (26.9%), and scarcely used in 25 procedures (12%). The device was considered to be very helpful in 166 procedures (79.8%) and helpful to some extent in 33 procedures (15.9%). In 8 (3.8%) procedures, it was not helpful, and in 1 procedure (0.5%), the usefulness was not documented by the surgeon. The water jet dissector can be applied easily and very safely. Precise tissue dissection with preservation of blood vessels and no greater risk of complications are possible. However, the clinical consequences of the described qualities need to be demonstrated in a randomized clinical trial.

    Complications after surgical procedures in patients with cardiac implantable electronic devices (CIED) are an emerging problem due to an increasing number of such procedures and aging of the population, which consequently increases the frequency of comorbidities. To identify the rates of postoperative complications, mortality, and hospital readmissions, and evaluate the risk factors for the occurrence of these events. Prospective and unicentric study that included all individuals undergoing CIED surgical procedures from February to August 2011. The patients were distributed by type of procedure into the following groups: initial implantations (cohort 1), generator exchange (cohort 2), and lead-related procedures (cohort 3). The outcomes were evaluated by an independent committee. Univariate and multivariate analyses assessed the risk factors, and the Kaplan-Meier method was used for survival analysis. A total of 713 patients were included in the study and distributed as follows: 333 in cohort 1, 304 in cohort 2, and 76 in cohort 3. Postoperative complications were detected in 7.5%, 1.6%, and 11.8% of the patients in cohorts 1, 2, and 3, respectively (p = 0.014). During a 6-month follow-up, there were 58 (8.1%) deaths and 75 (10.5%) hospital readmissions. Predictors of hospital readmission included the use of implantable cardioverter-defibrillators (odds ratio [OR] = 4.2), functional class III--IV (OR = 1.8), and warfarin administration (OR = 1.9). Predictors of mortality included age over 80 years (OR = 2.4), ventricular dysfunction (OR = 2.2), functional class III-IV (OR = 3.3), and warfarin administration (OR = 2.3). Postoperative complications, hospital readmissions, and deaths occurred frequently and were strongly related to the type of procedure performed, type of CIED, and severity of the patient's underlying heart disease.

    To determine the association (1) between shorter operative duration and surgical site infection (SSI) and (2) between surgeon median operative duration and SSI risk among first-time hip and knee arthroplasties. Retrospective cohort study A total of 43 community hospitals located in the southeastern United States. Adults who developed SSIs according to National Healthcare Safety Network criteria within 365 days of first-time knee or hip arthroplasties performed between January 1, 2008 and December 31, 2012. Log-binomial regression models estimated the association (1) between operative duration and SSI outcome and (2) between surgeon median operative duration and SSI outcome. Hip and knee arthroplasties were evaluated in separate models. Each model was adjusted for American Society of Anesthesiology score and patient age. A total of 25,531 hip arthroplasties and 42,187 knee arthroplasties were included in the study. The risk of SSI in knee arthroplasties with an operative duration shorter than the 25th percentile was 0.40 times the risk of SSI in knee arthroplasties with an operative duration between the 25th and 75th percentile (risk ratio [RR], 0.40; 95% confidence interval [CI], 0.38-0.56; P<.01). Short operative duration did not demonstrate significant association with SSI for hip arthroplasties (RR, 1.04; 95% CI, 0.79-1.37; P=.36). Knee arthroplasty surgeons with shorter median operative durations had a lower risk of SSI than surgeons with typical median operative durations (RR, 0.52; 95% CI, 0.43-0.64; P<.01). Short operative durations were not associated with a higher SSI risk for knee or hip arthroplasty procedures in our analysis.

    Full Text Available Background: The aim of this study was to assess how the chosen socio-demographic factors effect the quality of life in the patients after gynaecological surgical procedures. Materials and Methods: Research was conducted in 2007 among 250 women operated in the Department of Reproduction and Gynaecology, the Pomeranian Medical University in Szczecin. In this survey-based study, we used a standardized quality of life questionnaire, the Women’s Health Questionnaire (WHQ, developed by Dr Myra Hunter at London University. Results: The most numerous patients were those with sleep disorders (38,8%, 37,6% of the surveyed complained of troublesome menstrual symptoms, 26,8% of respondents had disturbing somatic symptoms, short memory and problems with concentration. The lowest percentage of women (12,4% felt anxiety and fear associated with the past gynaecological surgical procedure. Conclusions: 1. General satisfaction and good disposition is declared by the majority of patients after gynaecological surgical procedures. 2. Age, education, having a partner, place of residence, and the number of children are the factors which have significant effect on the quality of life in women after gynaecological procedures.

    Full Text Available Introduction: Modern medicine uses increasingly innovative techniques that require more and more capabilities for acquisition. In the urological department is increasing the presence of patients with lower urinary tract symptoms (LUTS and transurethral resection of the prostate (TURP is the standard of care in their surgical treatment. We report our surgical experience and learning curve of using bipolar plasmakinetic devices in the training of urological residents to benign prostatic hyperplasia (BPH treatment. Materials and Methods: 80 patients with benign prostatic enlargement due to BPH were enrolled in the study. TURP has been performed by three urological residents and by an expe- rienced urologist. Patients were evaluated before and 6 months after the endoscopic bipolar plasmakinetic resection using the International Prostate Symptom Score (IPSS, maximum uri- nary flow rate (Qmax, postvoid residual urine (PVR and prostate specific antigen (PSA. Results: Overall 60 procedures were performed, 18 PlasmaKinetic (PK-TURP procedures were completed by the three residents. In the other 42 cases the procedures were completed by the experienced urologist. In eight cases there was a capsular perforation and the experienced urol- ogist replaced the resident to complete the resection. No complications have been reported in the procedures completed by the senior urologist. All complications caused by the residents were man- aged intraoperatively without changing the course of the procedure. Statistical differences were observed regarding IPSS, quality of life (QoL, and PVR at 6-month follow-up when procedures completed by urological residents were compared to those completed by the senior urologist. Conclusion: Bipolar device represents appropriate tools to acquire endoscopic skills. It is safe and it can be used at the first experience of BPH treatment by a resident who has not previ- ously approached this endoscopic surgical procedure.

    Konh, Bardia

    Background: Majority of cancer interventions today are performed percutaneously using needle-based procedures, i.e. through the skin and soft tissue. Insufficient accuracy using conventional surgical needles motivated researchers to provide actuation forces to the needle's body for compensating the possible errors of surgeons/physicians. Therefore, active needles were proposed recently where actuation forces provided by shape memory alloys (SMAs) are utilized to assist the maneuverability and accuracy of surgical needles. This work also aims to introduce a novel needle insertion simulation to predict the deflection of a bevel tip needle inside the tissue. Methods: In this work first, the actuation capability of a single SMA wire was studied. The complex response of SMAs was investigated via a MATLAB implementation of the Brinson model and verified via experimental tests. The material characteristics of SMAs were simulated by defining multilinear elastic isothermal stress-strain curves. Rigorous experiments with SMA wires were performed to determine the material properties as well as to show the capability of the code to predict a stabilized SMA transformation behavior with sufficient accuracy. The isothermal stress-strain curves of SMAs were simulated and defined as a material model for the Finite Element Analysis of the active needle. In the second part of this work, a three-dimensional finite element (FE) model of the active steerable needle was developed to demonstrate the feasibility of using SMA wires as actuators to bend the surgical needle. In the FE model, birth and death method of defining boundary conditions, available in ANSYS, was used to achieve the pre-strain condition on SMA wire prior to actuation. This numerical model was validated with needle deflection experiments with developed prototypes of the active needle. The third part of this work describes the design optimization of the active using genetic algorithm aiming for its maximum flexibility

    Surgical teams need to breathe air that is conducive to their health. An adequate exchange of air ensures oxygen supply, the ventilation of humidity, smells, toxic substances, especially narcotic gases and surgical smoke, pathogens and particles. With regard to the infection risk, DIN 1946 / 4 -differentiates between operation theaters with the highest demand for clean air (operation room class I a), operation theatres with a high demand (operation room class I b) and rooms within the operation theatres without special requirements, meaning that the microbial load in the air is close to or equal to that of normal in-room air quality (room class II). For an operation room class I a, ventilation that displaces the used air is necessary, while a regular ventilation is sufficient for operation room class I b. Because of ambiguous -results in previous studies, the necessity to define a -class I a for operation rooms is being questioned. Therefore, this review focuses on the analysis of the existing publications with respect to this -question. The result of this analysis indicates that so far there is only one surgical procedure, the -implantation of hip endoprosthetics, for which a preventive effect on SSI of a class I a ventilation (displacement of the used air) is documented. One recent study, reviewed critically here, -showed opposite results, but lacks methodological clarity. Thus, it is concluded that evidence for the requirement of operation room classes can only be derived from risk assessment (infection risk by surgical intervention, extent of possible damages), but not from epidemiological studies. Risk assessment must be based on the following criteria: size and depth of the operation field, -duration of the procedure, vascular perfusion of the wound, implantation of alloplastic material and general risk of the patient for an infection. From an infection preventive point of view, no class I a "displacement ventilation" is necessary for small surgical

    To introduce a new surgical procedure for penile reconstruction, emphasizing both the aesthetic appearance and the function by combined free radial forearm flap and dorsalis pedis flap. In this procedure, the penis was subdivided into 2 anatomic subunits: the penile shaft and the glans penis. A sequential innervated radial forearm free flap was combined with a dorsalis pedis free flap to reconstruct the penile shaft and the glans, separately. Cartilage prosthesis was implanted at the same time. Since May 2011, 14 biologically male patients with total penile losses by various reasons were treated with this procedure. Patient satisfaction was evaluated by questionnaire, and sensory testing was performed. The ages of the patients ranged between 21 and 53 years (mean, 35.2 years). The average follow-up period was 38.1 months (range, 25.5-56 months). Twenty-five flaps in 11 patients were 100% viable. One dorsalis pedis flap in a patient underwent partial necrosis. There were no cases of urethral fistula or urethral stenosis, but 1 case of prosthesis infection and 1 case of abdominal hernia were recorded. The sensation of the neophallus recovered 3-6 months after surgery, and the patient satisfaction rate was quite high. The new surgical procedure of combined free radial forearm flap and dorsalis pedis flap for penile reconstruction achieves both satisfactory aesthetic and functional results. We recommend this procedure as an alternative ideal method for total penile reconstruction. Copyright © 2016 Elsevier Inc. All rights reserved.

Methods: A total of 54 patients were retrospectively reviewed, 35 patients underwent subradical hysterectomy and 19 patients received radical hysterectomy, both with simultaneous bilateral salpingo-oophorectomy and pelvic and paraaortic lymphadenectomy. Results: Comparing the surgical outcomes in subradical hysterectomy group vs radical hysterectomy group, there were no significant differences in operative time, estimated blood loss, and hospital stay. After surgery, 37.1% vs 36.8% patients received postoperative radiotherapy in the subradical hyster­ectomy group vs radical hysterectomy group, without statistically significant difference. As for postoperative complications, the early postoperative complication rate in patients who underwent subradical hysterectomy was 14.3%, significantly lower than that in patients submitted to radical hysterectomy (14.3% vs 42.1%, with P=0.043. However, there was no significant difference in late postoperative complication rate between the two surgical procedures. Regarding the clinical prognosis, patients receiving the subradical hysterectomy showed similar survival to their counterparts undergoing the radical procedures. The relapse rate was 5.71% vs 5.26%, respectively, without significant difference. There were no deaths in both surgical groups. Conclusion: For stage II endometrial carcinoma, subradical hysterectomy presented with less early postoperative complications and similar survival duration and recurrence

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reasons is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which must include five requirements: a) visual fidelity, b) interactivity, c) physical properties, d) physiological properties, e) sensory input and output. In this report we describe how to obtain a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction.

A total of 1088 congenital heart surgeries (CHS), performed from 2005 to 2010, were reviewed. A total of 750 cases did not receive magnesium, and 338 cases received magnesium (25 mg/kg). All procedures were classified according to Aristotle score from 1 to 4. Overall, there was a statistically significant decrease in PO JET occurrence between the two groups regardless of the Aristotle score, 15.3 % (115/750) in non-magnesium group versus 7.1 % (24/338) in magnesium group, P < 0.001. In the absence of magnesium, the risk of JET increased with increasing Aristotle score, P = 0.01. Following magnesium administration and controlling for body weight, surgical and aortic cross-clamp times in the analyses, reduction in adjusted risk of JET was significantly greater with increasing Aristotle level of complexity (JET in non-magnesium vs. magnesium group, Aristotle level 1: 9.8 vs. 14.3 %, level 4: 11.5 vs. 3.2 %; odds ratio 0.54, 95 % CI 0.31-0.94, P = 0.028). Our data confirmed that intra-operative usage of magnesium reduced the occurrence of PO JET in a larger number and more diverse group of CHS patients than has previously been reported. Further, our data suggest that magnesium's effect on PO JET occurrence seemed more effective in CHS with higher levels of Aristotle complexity.

    Flail chest is a life-threatening situation that paradoxical movement of the thoracic cage was caused by multiply fractured ribs in two different planes, or a sternal fracture, or a combination of the two. The methods to achieve stability of the chest wall are controversy between surgical fixation and mechanical ventilation. We report a case of a 33-year-old man who fell from a high place with fail chest due to multiple rib fractures bilaterally and horizontal sternal fracture. The conventional surgical stabilization using metal plates by access to the front of the sternum could not provide stability of the flail segment because the fracture surface was obliquely upward and there were multiple bilateral rib fractures adjacent the sternum. The Nuss procedure was performed for supporting the flail segment from the back. Flail chest was resolved immediately after the surgery. The patient was weaned from the mechanical ventilation on third postoperative day successfully and was ultimately discharged without any complications.

    The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of {sup 18}F-FDG. Mean patient dosage of {sup 18}F-FDG was 699 {+-} 181 MBq (range 451-984). Mean time from {sup 18}F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 {+-} 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 {+-} 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 {+-} 135 {mu}Sv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 {+-} 134 {mu}Sv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in {sup 18}F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in {sup 18}F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

    The incidence of hepatocellular carcinoma (HCC) has increased worldwide over the past two decades. Surgical resection and liver transplantation have been demonstrated as potentially curative treatment options, which could be considered in 30% -40% of HCC patients. Recent advancements of surgical treatment have focused not only on the surgical techpiques, but also the hepatic functional reserve evaluation, resectability assessment and the effects of biological characteristics of tumor on prognosis. There is no single variable to evaluate the hepatic functional reserve accurately. Combined Child-Pugh classification, ICGI5, portal vein pressure detection and remanent liver volume measurement are required prior to liver resection. The 5-year survival rate after liver resection for HCC is about 50%. The results are acceptable for some selected patients that underwent tumor resection with thrombectomy, including HCC with portal vein tumor thrombus or bile duct thrombosis. The choice of local resection or regular hepatectomy is still controversial although the former is commonly performed to treat HCC with cirrhosis, and the latter is applied to HCC patients without liver cirrhosis. The results of liver transplanta-tion for HCC are better than liver resection, and the Milan criteria is generally accepted. Any attempts to expand the selection criteria should be cautious because of organ shortage. Salvage transplantation for intrabepatic recurrence after liver resection may be a good choice in some resectable HCC. The recurrence and metastasis after surgical treatment are the main obstacles to achieve better results. Identification of predictive factors could be helpful to develop prevention strategies. Due to the importance of biological characteristics in tumor recurrence and metastasis, a molecular classification to predict prognosis of HCC patients will lead to a more personalized medicine. Targeting key molecules of biological pathways could optimize the therapeutic

    Adults with hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD) frequently require surgery and invasive procedures. However, there is variability in perioperative management guidelines. We describe our periprocedural outcomes in this setting. A retrospective chart review from January 2006 to December 2012 of patients with HA, HB, and VWD undergoing surgery or invasive procedures was conducted. Type of procedures, management including the use of continuous factor infusion, and administration of antifibrinolytics were reviewed. Adverse outcomes were defined as acute bleeding (patients with HA and HB. In all, 24 patients had severe hemophilia and 12 had mild/moderate hemophilia. Twelve patients had inhibitors. There were also 5 female carriers of HA and 6 patients with VWD. There were 34 major surgeries (26 orthopedic, 8 nonorthopedic) and 129 minor surgeries. Continuous infusion was used in 55.9% of major surgeries versus 8.5% of minor surgeries. Antifibrinolytics were administered in 14.7% of major surgeries versus 23.2% of minor surgeries. In all, 4 patients developed acute bleeding and 10 patients developed delayed bleeding. Delayed bleeding occurred in 28.6% of genitourinary procedures and in 16.1% of dental procedures. Five patients acquired an inhibitor and 2 had thrombosis. In conclusion, patients with HA, HB, or VWD had similar rates of adverse outcomes when undergoing minor surgeries or major surgeries. This finding underscores the importance of an interdisciplinary management and procedure-specific guidelines for patients with hemophilia and VWD prior to even minor invasive procedures.

    Full Text Available Introducation: The long-term outcome and clinical results of gaparthroplasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared. The purpose of this study was to compare the effect of gap arthroplasty and costochondral graft methods on reankylosis, a mount of mouth opening and growth. Materials and Methods: A non-randomized, retrospective clinical study of l0 cases (5-12 years old of condylar ankylosis of the mandible, surgically treated during a 10 year period from 2002 to 2012 was performed. Four patients were treated by condylectomy and interpositional flap, whereas six were treated by condylectomy and immediate costachondral rib grafts. The first group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, and computed tomography (CT were used post surgically to evaluate rib graft, condylar growth and function, occlusion, facial, and condylar symmetry. Data were analyzed by SPSS 16 statistical software using Mann-Whitney, Paired T-test and Chi-square tests. Results: Children with long-standing condylar ankylosis of the mandible treated by condylectomy and interpositional flap showed more favorably when activators were used post-surgically. Conclusions: Gaparthroplasty with functional activator post-operatively can be considering for TMJ ankylosis.

    Full Text Available Simulation can be defined as malingering, or sometimes functional visual loss (FVL. It manifests as either simulating an ophthalmic disease (positive simulation, or denial of ophthalmic disease (negative simulation. Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today’s world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician’s responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test(s to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of optical coherence tomography, frequency doubling perimetry (FDP, and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up-to-date information on malingering or simulation in ophthalmology.

    Small renal masses (T1a) are commonly diagnosed incidentally and can be treated with nephron-sparing surgery, preserving renal function and obtaining the same oncological results as radical surgery. Bigger lesions (T1b) may be treated in particular situations with a conservative approach too. We present our surgical technique based on robotic assistance for nephron-sparing surgery. We retrospectively analysed our series of 32 consecutive patients (two with 2 tumours and one with 4 bilateral tumours), for a total of 37 robotic nephron-sparing surgery (RNSS) performed between June 2008 and July 2012 by a single surgeon (G.C.). The technique differs depending on tumour site and size. The mean tumour size was 3.6 cm; according to the R.E.N.A.L. Nephrometry Score 9 procedures were considered of low, 14 of moderate and 9 of hight complexity with no conversion in open surgery. Vascular clamping was performed in 22 cases with a mean warm ischemia time of 21.5 min and the mean total procedure time was 149.2 min. Mean estimated blood loss was 187.1 ml. Mean hospital stay was 4.4 days. Histopathological evaluation confirmed 19 cases of clear cell carcinoma (all the multiple tumours were of this nature), 3 chromophobe tumours, 1 collecting duct carcinoma, 5 oncocytomas, 1 leiomyoma, 1 cavernous haemangioma and 2 benign cysts. Associated surgical procedures were performed in 10 cases (4 cholecystectomies, 3 important lyses of peritoneal adhesions, 1 adnexectomy, 1 right hemicolectomy, 1 hepatic resection). The mean follow-up time was 28.1 months ± 12.3 (range 6-54). Intraoperative complications were 3 cases of important bleeding not requiring conversion to open or transfusions. Regarding post-operative complications, there were a bowel occlusion, 1 pleural effusion, 2 pararenal hematoma, 3 asymptomatic DVT (deep vein thrombosis) and 1 transient increase in creatinine level. There was no evidence of tumour recurrence in the follow-up. RNSS is a safe and feasible technique

    In this Statistical Grand Rounds, we review methods for the analysis of the diversity of procedures among hospitals, the activities among anesthesia providers, etc. We apply multiple methods and consider their relative reliability and usefulness for perioperative applications, including calculations of SEs. We also review methods for comparing the similarity of procedures among hospitals, activities among anesthesia providers, etc. We again apply multiple methods and consider their relative reliability and usefulness for perioperative applications. The applications include strategic analyses (e.g., hospital marketing) and human resource analytics (e.g., comparisons among providers). Measures of diversity of procedures and activities (e.g., Herfindahl and Gini-Simpson index) are used for quantification of each facility (hospital) or anesthesia provider, one at a time. Diversity can be thought of as a summary measure. Thus, if the diversity of procedures for 48 hospitals is studied, the diversity (and its SE) is being calculated for each hospital. Likewise, the effective numbers of common procedures at each hospital can be calculated (e.g., by using the exponential of the Shannon index). Measures of similarity are pairwise assessments. Thus, if quantifying the similarity of procedures among cases with a break or handoff versus cases without a break or handoff, a similarity index represents a correlation coefficient. There are several different measures of similarity, and we compare their features and applicability for perioperative data. We rely extensively on sensitivity analyses to interpret observed values of the similarity index.

    To describe trends in the utilization of surgical procedures for pelvic organ prolapse among women in Olmsted County, MN, we retrospectively identified all county residents undergoing pelvic organ prolapse repair from January 1, 1965 through December 31, 2002. From 1965 to 2002, 3,813 women had pelvic organ prolapse surgeries: 3,126 had hysterectomy combined with pelvic floor repair (PFR) procedures and 687 had PFR alone. The age-adjusted utilization of hysterectomy plus PFR and of PFR alone decreased by 62% (P PFR and women aged 70 years and older undergoing PFR only. The most common indication for PFR was uterovaginal prolapse. Among women in the community, the rate of utilization and age distribution of pelvic organ prolapse surgery changed substantially between 1965 and 2002.

    To determine the frequency of bacteriuria in dogs presenting for elective surgery, to compare the frequency of bacteriuria in dogs presenting for orthopaedic (non-neurological) procedures to that of dogs presenting for soft tissue procedures and to measure the agreement of microscopic visualisation of bacteria in urine sediment with the occurrence of bacterial growth on culture. Prospective cohort study of 140 client-owned dogs. Urine was collected via prepubic cystocentesis prior to or immediately after induction of anaesthesia. Urine was submitted for quantitative bacteriological culture and urinalysis. The dogs' age, sex, weight and breed were recorded, as well as the surgical procedure performed. In total, 80 orthopaedic and 60 soft tissue surgical cases were included in the study; 3 dogs (2.1%) returned bacterial growth on culture (positive urine culture) and 19 (13.6%) recorded urine sediment with pyuria and/or bacteriuria on urinalysis (positive urinalysis). All dogs with positive urine culture were female and two of them underwent orthopaedic procedures. Each bitch had growth of Escherichia coli >10(5)  CFU/mL. The agreement between positive urinalysis and positive urine culture was poor (κ = 0.15). The prevalence of bacteriuria in dogs without clinical signs of urinary tract infection in this population was low (2.1%). An at-risk population could not be identified because of the small number of positive outcomes. A positive urinalysis showed poor agreement with urine culture results and therefore the decision to treat without performing a urine culture is not advised. © 2014 Australian Veterinary Association.

    Management of pacemaker infection in pacing-dependent patients is often challenging. Typically, temporary pacing is used while antibiotic therapy is given for a number of days before reimplantation of a new endocardial system. This results in a prolonged hospital stay and complications associated with temporary pacing. In this study, we examine the feasibility of performing a single combined procedure of epicardial pacemaker implantation followed by system extraction. One hundred consecutive infected pacemaker-dependent patients underwent implantation of 2 epicardial ventricular leads and were converted to a ventricular demand pacing system. The infected pacing system was then extracted during the same procedure. Patients were followed up for 12 months. Significant pericardial bleeding developed during the procedure in 3 patients. The presence of the pericardial drain positioned during the implantation of the epicardial pacing system meant that cardiac tamponade did not occur, allowing surgical repair with sternotomy to be carried out under stable hemodynamic conditions. Two of these 100 patients died in the 30-day postoperative period; 1 death was due to septic shock and 1 to pulmonary distress. Median 1-year epicardial pacing thresholds were stable and excellent (1.4 ± 0.9 volts). However, 1 of the 2 leads developed increased thresholds in 6 patients, which led to the exclusive use of other ventricular lead. A single combined procedure of surgical epicardial pacemaker implantation and pacemaker system extraction appears to be a safe and effective method for managing pacemaker-dependent patients with infected pacemakers.

    Topical antibiotics are not indicated for postsurgical wound infection prophylaxis in clean and clean-contaminated dermatologic surgeries, yet many dermatologists continue to prescribe them. The objective of our systematic review and meta-analysis was to critically assess the efficacy of topical antibiotics in terms of preventing postsurgical wound infections in the dermatology outpatient setting. PubMed, Embase, MD Consult, Science Direct, Springer Link, DynaMed and Cochrane online medical databases were searched from 1980 to 2013. Using random effects modeling, the pooled odds ratio of developing a postsurgical wound infection was 0.71 (95% CI, 0.42-1.19). Pooled data of the four trials in the meta-analysis did not show a statistically significant difference in incidence of postsurgical wound infections between topical antibiotics and petrolatum/paraffin. In the setting of moist occlusive dressings, there is no statistically significant difference in prophylactic efficacy between applying and not applying ointment to surgical wounds. Wounds at increased risk of developing surgical site infections include wounds in diabetics, wounds located in certain anatomic regions, and wounds created by some surgical procedures. Petrolatum should be used instead of topical antibiotics as a prophylactic measure to prevent postsurgical wound infections in the outpatient dermatologic setting.

    Full Text Available Loss of interdental papilla predisposes to phonetic, functional, and esthetic problem. Surgical techniques are manifold, but are challenging and very unpredictable. The purpose of this case report is to present the use of platelet rich fibrin (PRF in the reconstruction of papilla in the maxiallry anterior region of a forty year old woman who presented with loss of interdental papillae in 11, 12 and 11, 21 region. PRF was tucked in to the pouch created with a semilunar pedicle flap and the entire gingivopapillary unit was displaced coronally. Optimal fill was noted at 3 and 6 months postoperatively. Use of PRF may thus be the panacea for interdental papilla augmentation.

    Complete cytoreductive surgery (CCRS) plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is the best-known treatment for pseudomyxoma peritonei (PMP). In 30% of the cases, PMP realize a widespread involvement of the peritoneal cavity. In these extreme situations, we developed, devoted strategies to optimize the feasibility and safety of CCRS. This study describes the surgical resections required for CCRS and the consequent approaches that we propose to achieve CCRS. We defined "huge PMP" by a peritoneal cancer index (PCI) ≥ 28. Surgical procedures of patients operated on between 1994 and 2014 were retrospectively reviewed from a prospective database in a single institution. During this period, 311 patients were operated on and 247 (79%) underwent CCRS + HIPEC. Among them, 100 patients presented "huge" PMP and 54 patients underwent CCRS + HIPEC. In patients with "huge" PMP, the rate of CCRS + HIPEC was 25% before 2002 and reached 71% between 2011 and 2014. We identified 3 conditions for CCRS 1) to guaranty a sufficient length of residual small bowel 2) to preserve the left gastric vessels in order to preserve the superior third of the stomach 3) to ensure that the hepatic pedicle can be entirely cleared from its tumor involvement. None of the other peritonectomy procedures were decisional for CCRS. Our learning curve improved the selection and completion rate of CCRS + HIPEC for "huge PMP". Some anatomical and physiological prerequisites guarantee the feasibility and safety of such extensive surgeries. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape. Following this procedure, her UTI completely resolved and she remained asymptomatic for several years. Seven years later she presented with a solid vaginal mass. Pelvic examination followed by transvaginal ultrasonography and magnetic resonance imaging demonstrated a large vaginal calculus located at the lower third of the anterior vaginal wall adjacent to the bladder neck. This video presents the transvaginal excision and removal of the vaginal calculus.

    Full Text Available Anaplastic carcinoma (AC or undifferentiated carcinoma of the pancreas is a rare variant among the malignant pancreatic neoplasms. These tumors have a poor prognosis with survival measured in months. The role of surgical palliation to improve the quality of life is not well defined in these patients. We report a case of AC of pancreas in a 65-year-old male patient. Patient had upper abdominal pain with frequent bilious vomiting. Computed tomography scan of the abdomen showed a mass in the body of pancreas with possible infiltration of duodenojejunal flexure (DJF. Laparotomy revealed an inoperable mass with posterior fixity and involvement of the DJF. Patient underwent a palliative duodenojejunostomy. Tissue biopsy from the tumor showed pleomorphic type AC with giant cells. Patient had good symptomatic relief from profuse vomiting and progressed well at follow up. AC of pancreas is a rare and aggressive malignancy with dismal outlook. If obstructive symptoms are present due to duodenal involvement, a palliative bypass may be a worthwhile surgical option in selected cases.

    In 1997, the US Food and Drug Administration approved the use of intermittent stimulation of the left vagal nerve as adjunctive therapy for seizure control. Vagal nerve stimulation (VNS) has since been considered a safe and effective treatment for medically intractable seizures. The objective of this study is to present our experience with the surgical procedure and outcomes after VNS insertion in the first 100 consecutive patients treated at the Tel-Aviv "Sourasky" Medical Center (TASMC). All patients who underwent VNS device implantation by the authors at TASMC between 2005 and 2011 were studied. The collected data included age at onset of epilepsy, seizure type, duration of epilepsy, age at VNS device implantation, seizure reduction, surgical complications, and adverse effects of VNS over time. Fifty-three males and 47 females, age 21.2 ± 11.1 years, underwent VNS implantation. Indications for surgery were medically refractory epilepsy. The most common seizure type was focal (55 patients, 55 %). Seizure duration until implantation was 14.4 ± 9 years. Mean follow-up time after device insertion was 24.5 ± 22 months. Complications were encountered in 12 patients. The most common complication was local infection (6 patients, 6 %). Six devices were removed-four due to infection and two due to loss of clinical effect. Currently, 63 patients remain in active long-term follow-up; of these, 35 patients have >50 % reduction in frequency of attacks.VNS is a well-tolerated and effective therapeutic alternative in the management of medically refractory epilepsy. The surgical procedure is safe and has a low complication rate.

    @@ The first laparoscopic hepatectomy case was reportedby Reich et al1 in 1991. Initially the laparoscope was utilized diagnostically for resection and biopsy of superficial liver lesions. Recently due to the technological advancement and instrumental improvement, the laparoscopic hepatic resection procedures have evolved significantly. Among them, the caudate lobectomy is considered to be one of the most challenging surgeries on account of its unique anatomic location in the core of the liver within the abdomen. So far, there are only a few reported laparoscopic caudate lobectomy cases in the literature and the most cases were performed utilizing a traditional procedure.2,3

    Full Text Available Background: The impact of early mobilization on perioperative comorbidities and length of stay (LOS has shown benefits in other medical/surgical subspecialties. However, few spinal series have specifically focused on the "pros" of early mobilization for spinal surgery, other than in acute spinal cord injury. Here we reviewed how early mobilization and other adjunctive measures reduced morbidity and LOS in both medical and/or surgical series, and focused on how their treatment strategies could be applied to spinal patients. Methods: We reviewed studies citing protocols for early mobilization of hospitalized patients (day of surgery, first postoperative day/other in various subspecialties, and correlated these with patients′ perioperative morbidity and LOS. As anticipated, multiple comorbid factors (e.g. hypertension, high cholesterol, diabetes, hypothyroidism, obesity/elevated body mass index hypothyroidism, osteoporosis, chronic obstructive pulmonary disease, coronary artery disease and other factors contribute to the risks and complications of immobilization for any medical/surgical patient, including those undergoing spinal procedures. Some studies additionally offered useful suggestions specific for spinal patients, including prehabilitation (e.g. rehabilitation that starts prior to surgery, preoperative and postoperative high protein supplements/drinks, better preoperative pain control, and early tracheostomy, while others cited more generalized recommendations. Results: In many studies, early mobilization protocols reduced the rate of complications/morbidity (e.g. respiratory decompensation/pneumonias, deep venous thrombosis/pulmonary embolism, urinary tract infections, sepsis or infection, along with the average LOS. Conclusions: A review of multiple medical/surgical protocols promoting early mobilization of hospitalized patients including those undergoing spinal surgery reduced morbidity and LOS.

  7. Development and evaluation of accessories to improve the posture of veterinary surgeons in surgical procedures conducted in the field

    Full Text Available ABSTRACT The study was conducted based on the information collected on rural properties in the state of Goiás, during practical classes of Surgical Clinic in Large Animals at the Veterinary Hospital of the Escola de Veterinária e Zootecnia of the Universidade Federal de Goiás and during the implementation of outreach projects developed by the institution. An acropostite-phimosis surgical procedure in the bulls in the field was selected, lasting over 30 minutes and requiring movements, posture and strength on the part of the surgeon. Devices were proposed and developed to provide improved comfort and safety to surgeons. The first device was a stool to be used by the professional during the execution of the surgical intervention. The use enabled the surgeon to sit down and rest their feet on the ground, reducing knee bending and distributing the support forces in various muscle groups. For the movement restriction of the surgeon, another accessory was developed to support the foreskin of the animal. Made of wood, this other device serves as a support for keeping the foreskin away from the ground and close to the surgeon. Its length, width and thickness established a good relation with the stool height, providing minimal discomfort to the professional. The third device was designed to assist in the immobilization of the animal and increase safety for the patient and surgical team. A fourth accessory was designed to protect the scapular region and avoid the occurrence of injuries in the radial nerve, myopathies and traumas during the rollover or prolonged stay of the animal in lateral decubitus. The choice of the shape, dimensions and softness of the device was mainly based on the weight of the animal. Such devices have proven to be effective, reducing the time of surgery, making cervical and lumbar movement easier, in addition to providing better support to the surgeon, reducing risks of musculoskeletal diseases.

    2008-01-01

    Dexmedetomidine is an alpha2-adrenergic agonist that produces anxiolysis, amnesia, sedation, potentiation of opioid analgesia, and sympatholysis. It is currently approved by the U.S. Food & Drug Administration for the sedation of adults in the intensive care setting for up to 24 hours during mechanical ventilation. Given its beneficial sedative and anxiolytic properties and limited adverse effect profile, it has been used in several other clinical scenarios. The authors present their experience using dexmedetomidine for monitored anesthesia care (MAC) during "awake" ENT procedures such as thyroplasty, a procedure requiring a patient to verbalize when requested but to otherwise remain immobile to allow for completion of the procedure, and in a patient with post-polio syndrome with poor pulmonary reserve requiring esophagoscopy with dilation and botulinum toxin injection for cricopharyngeal dysfunction. Our preliminary experience suggests that dexmedetomidine provides effective sedation as the primary agent for MAC during such procedures in adult patients. The end-organ effects of dexmedetomidine and previous reports of its use during MAC are reviewed.

    2008-09-01

    Neuro-ophthalmology is facing a serious human resource issue. Few are entering the subspecialty, which is perceived as being poorly compensated compared with other subspecialties of ophthalmology. The low compensation comes from the fact that 1) non-procedural encounters remain undervalued, 2) efforts that benefit other medical specialists are not counted, and 3) the relatively low expenses of neuro-ophthalmologists are not factored into compensation formulas. Mission-based budgeting, which forces academic departments to be financially accountable without the expectation of fiscal relief from medical schools or practice plans, has exacerbated the compensation issue. Solutions must come from within neuro-ophthalmology, academic departments, medical schools, and medical practice plans. They include 1) providing educational resources so that neuro-ophthalmologists need not spend so much time teaching the basics, 2) factoring into compensation the impact of neuro-ophthalmologists in teaching and on revenue generation by procedure-based specialists, 3) improving the efficiency of neuro-ophthalmologists in their consultative practices by providing ample clerical support and other measures, 4) providing contractual salary compensation by departments such as neurosurgery to recognize the contributions made by neuro-ophthalmologists, and 5) reorganizing the academic clinical effort as multidisciplinary rather than departmental.

    The medical record not only stores information on actions taken regarding patient care but it is also a source of education for those who read it. Nurses, residents, interns, students and consulting clinicians look to the medical record to gain an understanding of clinical disease and the diagnostic studies and treatment regimens used to affect the disease. We have presented our initial findings and our framework for developing and evaluating The Surgical Illustrator, a software program that will enable clinicians to include in EMRs information that is usually hand drawn in traditional medical records. The future of the EMR will be a direct result of research and development devoted to creating innovative means of conveying clinically pertinent data. Our goal is to make a major contribution to this effort.

    Laparoscopic surgery is associated with a shallow learning curve. AnubiFiX embalming technique enables laparoscopic surgical training on supple embalmed and hence insufflatable human specimens in the dissection room. Aim of the present trial is to test whether dissection-based anatomy education is superior to classical frontal classroom education on the short and long term. A total of 112 medical students were randomized in three groups. Group I attended classroom education, group II laparoscopic dissection-based education and group III received both. All groups completed an anatomy test on human specimens before, immediately after and 3 weeks after the anatomy training. Group II and III scored significantly better compared to group I immediately after the anatomy training (p I-II superior outcomes on the short and long term, as compared to classical frontal classroom education.

    Full Text Available Carcinoma of the external auditory canal (EAC is an unusual head and neck malignancy. The pathophysiology of these tumors is different from other skin lesions because of their anatomical and functional characteristics. Early-stage carcinoma of the EAC can be generally cured by surgical treatment, and reconstruction of the EAC with a tympanoplasty can help to retain hearing, thus improving the patients’ quality of life. In this study, we present two cases of early-stage carcinoma of the EAC treated by canal reconstruction using skin grafts after lateral temporal bone resection. A rolled-up skin graft with a temporal muscle flap was useful for keeping the form and maintaining the postoperative hearing. An adequate size of the skin graft and blood supply to the graft bed are important for achieving a successful operation.

    Introduction: Laparoscopic gastric plication (LGCP) reduces gastric volume without resecting or implanting a foreign body. Although still considered investigational, it could be appropriate for young patients with a low body mass index (BMI) and for those unwilling to undergo sleeve gastrectomy, gastric banding, or bypass. Objectives: The aim of this study was to assess the mid-term results (2 years) of LGCP in terms of safety and efficacy. Methods: A total of 56 obese patients (47 female; mean age=30.5±11.7 years; mean BMI=40.31±4.7 kg/m(2)) were candidates for LGCP from January 2011 to October 2013. Early and late complications, BMI, and excess BMI loss (EBL) were prospectively recorded at 3, 6, 9, 12, 18, and 24 months follow-up. Results: Mean operative time was 72.4±15.6 minutes. No conversion was required. Mean hospital stay was 3 days. Mean %EBL was 34.3±18.40%, 40.1±24.5%, 47.4±30.2%, 46.5±34.6%, 47.8±43.2%, and 55.3±53.6% at 3, 6, 9, 12, 18, and 24 months, respectively. The overall complication rate was 32.14%. Perioperative mortality was zero. Surgical revision was needed in 30 patients: 12 for unsatisfactory weight loss and 18 for gastric prolapse (one acute within 30 days), respectively. Conclusion: LGCP showed high complication rates requiring surgical revision.

    While laparoscopic surgery can be performed using small skin incisions, any resected specimen must still be able to fit through these opening. For procedures, such as cholecystectomies and appendectomies, this is not usually a problem; however, for large specimens such as bowel or large tumors, this becomes problematic. Currently, the standard technique is to attempt piecemeal removal of the specimen or enlarge one of the laparoscopic incisions, effectively creating a mini laparotomy. Creatin...

While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications.

    Full Text Available Background/Aim. Esotropia is the most common manifestation form of strabism accompanied by refraction deviations and amblyopia. The aim of this prospective study was to present the outcomes of surgical treatment of esotropia in children and adolescents. Methods. Within the period from January 1st 2006 to February 1st 2007 at the Clinic for Ophtalmology, Military Medical Academy, Belgrade a total of 25 patients with esotropia (34 eyes and previously corrected refraction anomaly and treated amblyopia were operated on. The patients were 4-19-year of age. All of the patients were submitted to a complete ophtalmologic and orthoptic examination prior to the surgery, and a month, three months and six months after the surgery. The surgery was performed under general anesthesia. Out of the total number of the patients nine were operated on both eyes, while 16 patients on one eye with amblyopia or frequent esodeviation. Nine patients were submitted to retroposition of the inner straight muscle, two to myectomy of the outer straight muscle, while in 14 of the patients a combination of retroposition and myectomy was performed. The patients were divided into three groups according to the preoperative angle at the distance and followed-up accordingly after the surgery. Deviation angle at the distance in the group I was 18-25 DP, in the group II 26-35 PD, while in the group III it was 36-60 PD. Results.

    Is studying and control of the clinical efficacy and safety of ketoprofen lysine salt (КLS) (the commercial name is "Oki" manufacturer by Dompe CPA, Italy) in the form of sachets and solutions for application in postoperative period after dental surgeries procedures. The comparison of the analgetic effect of systemic and local forms of the "Oki" drug, depending on the type and extent of surgery procedures. Was carried out surgical treatment and patients examination in the postoperative period. Surgical procedures included: vestibulolasty, vestibulolasty with apically-displaced flap, vestibulolasty with apically-displaced flap and a free palatal mucogingival graft, removal impacted and dystopic teeth, periodontal surgery. The research was conducted in the Surgical stomatology and Maxillofacial surgery Department (stomatological policlinic of the Nizhny Novgorod State Medical Academy). Was noted rapid advanced of anesthesia when using sachets and solutions of the ketoprofen lysine salt (the commercial name is "Oki" manufacturer by Dompe CPA, Italy) in postoperative period after dental surgical procedures. Was noted a more advanced of analgetic effect in the application therapy by DCI solution when open surgical wound presented. Analgetic effect was observed after 20-30 min and was maintained in the postoperative period to an average of 8 hours. Local application sachets and solution of the ketoprofen lysine salt (KLS ), in our opinion, is the most appropriate and is highly effective when open surgical wound presented. Ketoprofen lysine salt (KLS) has a neutral pH and does not irritate the gastrointestinal tract, that determines the safety of its used.

    Background Simultaneous osteoarthritis (OA) of the ankle joint complicates primary total knee arthroplasty (TKA). In such cases, rehabilitation of TKA is limited by debilitating ankle pain, but varus or valgus ankle arthritis may even compromise placement of knee prosthetic components. Case presentation We present a patient with simultaneous bilateral valgus and patellofemoral OA of the knees and bilateral varus OA of the ankle joints that equally contributed to overall disability. This 63 years old, motivated and otherwise healthy patient was treated by simultaneous bilateral total knee and ankle arthroplasty (quadruple total joint arthroplasty, TJA) during the same anesthesia. Two years outcome showed excellent alignment and function of all four replaced joints. Postoperative time for rehabilitation, back to work (6th week) and hospital stay (12 days) of this special patient was markedly reduced compared to the usual course of separate TJA. Conclusions Simultaneous quadruple TJA in equally disabling OA of bilateral deformed knees and ankles resulted in a better functional outcome and faster recovery compared to the average reported results after TKA and TAA in literature. However, careful preoperative planning, extensive patient education, and two complete surgical teams were considered essential for successful performance. To the best of our knowledge this is the first case report in literature about quadruple major total joint arthroplasty implanted during the same anesthesia in the same patient. PMID:21995682

    Full Text Available Background and Objectives: The purpose of this study was to evaluate the positional changes of the periodontal tissues, particularly the biological width, following surgical crown-lengthening in human subjects. Materials and Methods: A clinical trial study involving 15 patients was carried out for a period of 6 months. Sites were divided into 3 groups: treated (TT sites, adjacent (AD sites and nonadjacent (NAD sites. Free gingival margin [FGM], attachment level, pocket depth, bone level, biological width [BW] were recorded at baseline, 1, 3 and 6 months. Direct bone level after flap reflection was recorded before and after osseous resection at baseline only. Level of osseous crest was lowered based on BW, and supracrestal tooth structure needed using a combination of rotary and hand instruments. Statistical Analysis: Student t test and ANOVA were used. Results: Overall, apical displacement of FGM at TT, AD and NAD sites was statistically significant compared to baseline. The apical displacement of FGM at TT site was more when compared to that at AD and NAD sites at 3 and 6 months. The BW at the TT site was smaller at 1, 3 and 6 months compared to that at baseline. However, at all sites, BW was reestablished to the baseline value at the end of 6 months. Interpretation and Conclusion: The BW at TT sites was reestablished to its original vertical dimension by 6 months. In addition, a consistent 2-mm gain of coronal tooth structure was observed at the 1, 3 and 6-month examinations.

    Surgeons perform complex tasks while exposed to multiple distracting sources that may increase stress in the operating room (e.g., music, conversation, and unadapted use of sophisticated technologies). This study aimed to examine whether such realistic social and technological distracting conditions may influence surgical performance. Twelve medical interns performed a laparoscopic cholecystectomy task with the Xitact LC 3.0 virtual reality simulator under distracting conditions (exposure to music, conversation, and nonoptimal handling of the laparoscope) versus nondistracting conditions (control condition) as part of a 2 x 2 within-subject experimental design. Under distracting conditions, the medical interns showed a significant decline in task performance (overall task score, task errors, and operating time) and significantly increased levels of irritation toward both the assistant handling the laparoscope in a nonoptimal way and the sources of social distraction. Furthermore, individual differences in cognitive style (i.e., cognitive absorption and need for cognition) significantly influenced the levels of irritation experienced by the medical interns. The results suggest careful evaluation of the social and technological sources of distraction in the operation room to reduce irritation for the surgeon and provision of proper preclinical laparoscope navigation training to increase security for the patient.

  4. POEM Procedure: What the Radiologist Needs to Know for This New Surgical Intervention for Achalasia.

    Achalasia is a debilitating condition resulting from the failure of appropriate lower esophageal sphincter relaxation. Traditionally, the treatment of choice for achalasia has been a Heller myotomy, performed either via laparotomy or laparoscopically. The latter method has gained wide popularity in its documented lower postoperative morbidity. Recently, however, a new technique has been developed that can be performed by both thoracic surgeons and endoscopists-Per-Oral Endoscopic Myotomy. This procedure offers an alternative to invasive surgery and provides excellent outcomes with minimal recovery time.(1) This article would help familiarize radiologists with this new technique, as well as both normal and abnormal postoperative appearances.

    To determine the percentage of publication misrepresentation among applicants to an ophthalmology residency, to compare that percentage with published percentages from other specialties, and to compare the number of US-trained applicants vs non-US-trained applicants found to misrepresent published articles. Published articles in peer-reviewed journals listed on residency applications to the Jones Eye Institute from October 10, 2000, to December 1, 2004, were searched, excluding applications that were unavailable or were from current residents and faculty. The type of misrepresentation of published articles and the country of medical school training were recorded. Compared were US-trained applicants vs non-US-trained applicants to determine which group was more likely to list published articles and which group was more likely to have a misrepresented published article. Eight hundred twenty-one of 852 applications (96.4%) were reviewed. Five hundred fifty applicants (67.0%) were from US medical schools, and 271 applicants (33.0%) were from non-US medical schools. Two hundred one applicants (24.5%) listed peer-reviewed published articles. Misrepresentation of published articles was found in 15 applicants (5 US trained and 10 non-US trained). The mean percentage of applicants with misrepresentation per applicant pool was 1.9%, while the mean percentage per applicants listing published articles was 8.1%. The most common misrepresentation found was self-promotion on the author list (50.0%), followed by omission of other authors (25.0%), nonexistent articles (12.5%), and nonauthorship (12.5%). Foreign medical graduates were more likely to list published articles (P = .008) and to have a misrepresented published article (P = .01). Ophthalmology has one of the lowest reported percentages of applicant publication misrepresentation in the literature. Foreign medical graduates were more likely to list published articles and to misrepresent published articles. Self-promotion on

    To investigate the association between intraoperative temperature and surgical site infection (SSI) in colorectal surgery with anesthesia information system data. Continuously measured intraoperative anesthesia information system temperature data for adult abdominal colorectal surgery procedures at a large tertiary center for 1 year were linked to 30-day American College of Surgeons National Surgical Quality Improvement Program SSI outcomes. Univariable and multivariable analyses of SSI to descriptive temperature statistics, absolute and relative temperature threshold times, and other clinically relevant variables were performed. Overall, 1008 patients (48% female, median age: 53 years) underwent major colorectal procedures (7% emergent, 72% open, 173 ± 95 minutes mean procedure time) with median intraoperative temperature 36.0°C, using active rewarming in 92% and 1-hour presurgical antibiotic administration in 91%. Thirty-day overall and organ/space infection rates were 17.4% (175) and 8.5% (86). Maximum, minimum, ending, and median temperatures were similar for those with or without SSI (36.6°C vs 36.5°C, 34.9°C vs 35.0°C, 36.4°C vs 36.2°C, and 36.1°C vs 36.0°C, P = not significant) and percent minutes using incremental cutoffs failed to correlate SSI with temperature. Absolute minutes for higher temperature cutoffs correlated with SSI because of longer procedure times. On multivariable analysis, factors associated with SSI were preoperative diabetes [odds ratio: 1.81 (1.07-3.07), P = 0.022] and blood loss of more than 500 mL [odds ratio: 1.61 (1.01-2.58), P = 0.047]. Although active rewarming remains an accepted and valid process measure, highly granular anesthesia information system temperature data did not demonstrate a correlation between temperature measures and SSI. SSI prevention efforts should focus on more efficacious interventions as opposed to currently mandated publicly reported normothermia measures.

    The reported maternal mortality for morbidly adherent placenta ranges from 7% to 10% worldwide. Current treatment modalities for this potentially life-threatening condition include radical approaches such as elective peripartum hysterectomy with or without bowel/bladder resection or ureteric re-implantation (for placenta percreta infiltrating these organs), and conservative measures such as compression sutures with balloon tamponade and the placenta remaining in situ. However, both conservative and radical measures are associated with significant maternal morbidity and mortality. The present article describes the Triple-P procedure-which involves perioperative placental localization and delivery of the fetus via transverse uterine incision above the upper border of the placenta; pelvic devascularization; and placental non-separation with myometrial excision and reconstruction of the uterine wall-as a safe and effective alternative to conservative management or peripartum hysterectomy.

    2015-01-01

    While laparoscopic surgery can be performed using small skin incisions, any resected specimen must still be able to fit through these opening. For procedures, such as cholecystectomies and appendectomies, this is not usually a problem; however, for large specimens such as bowel or large tumors, this becomes problematic. Currently, the standard technique is to attempt piecemeal removal of the specimen or enlarge one of the laparoscopic incisions, effectively creating a mini laparotomy. Creating a larger incision adds many of the drawbacks of open laparotomy and should be avoided whenever possible. In this article, we present a new technique of combining the repair of an inguinal hernia, umbilical hernia with a duodenal tumor resection in order to extract the specimen through the inguinal hernia orifice.

    Laparoscopy surgery has been widely used for many decades and combined laparoscopic procedures have become favorable choices for concomitant pathologies in the abdomen. However, the type of combination procedures and their safety in obese women have not been well elucidated in obese women. Here we retrospectively reported 147 obese women underwent combined laparoscopic gynecological surgery and cholecystectomy/appendicectomy in our hospital from January 2003 to December 2011. Of the total number of patients (n = 147), various laparoscopic gynecological surgeries were combined with laparoscopic cholecystectomy in 93 patients, and were combined with laparoscopic appendectomy in the rest 54 patients. Patients' ages ranged from 24 to 55 years with an average of 33 years. Our results showed that combined procedures caused various operative time and blood loss, with no difference considering the time to resume oral intake and length of hospital stay. Intraoperative complications occurred in a total of 7 patients (4.8%). None of the patients suffered from major complications after laparoscopic surgery, and minor postoperative complications occurred in 30 patients (20.4%). The follow-up period ranged from 6 to 24 months (average, 18.5 months). None of the patients developed complications during follow-up, except that one patient suffered from colporrhagia. Our results further suggest that the combined abdominal laparoscopic procedures of gynecologic and general surgery are safe and economic choices for obese women, and benefit patients in many ways including lesser pain, shorter hospital stays and earlier recovery.

    Curcumin (diferuloylmethane) is the main curcuminoid of the popular Indian spice turmeric (Curcuma longa). In the last 50 years, in vitro and in vivo experiments supported the main role of polyphenols and curcumin for the prevention and treatment of many different inflammatory diseases and tumors.The anti-inflammatory, antioxidant, and antitumor properties of curcumin are due to different cellular mechanisms: this compound, in fact, produces different responses in different cell types. Unfortunately, because of its low solubility and oral bioavailability, the biomedical potential of curcumin is not easy to exploit; for this reason more attention has been given to nanoparticles and liposomes, which are able to improve curcumin's bioavailability. Pharmacologically, curcumin does not show any dose-limiting toxicity when it is administered at doses of up to 8 g/day for three months. It has been demonstrated that curcumin has beneficial effects on several ocular diseases, such as chronic anterior uveitis, diabetic retinopathy, glaucoma, age-related macular degeneration, and dry eye syndrome. The purpose of this review is to report what has so far been elucidated about curcumin properties and its potential use in ophthalmology.

  12. [Anesthesia in ophthalmology (author's transl)].

    General anesthesia in ophthalmological surgery has become a great fashion. However there are still many problems especially in intraocular surgery. The eye with normal intraocular pressure generally needs no special technique. Most of the usual anesthesia produce a slight hypotonia with the exception of Succinylcholine, whose effect is contrary. Unfortunately this is not the case in eyes with pathologically increased intraocular pressure as in the different forms of glaucoma. Eye surgeons and anesthesists therefore look for solutions to this problem which in principle consist in the application of medicaments, which not seldom are rather agressive. The controlled hypotension by ganglion blockers, the curarisation in the state of being awake, the rapid perfusion of solutions with high osmotique effect (isolated or associated) represent such measures. The one has the disadvantage to be applied during so-called subvigile anesthesias where the security that the patient is asleep is rather doubtful; the other has the disadvantage that it requires a rapid perfusion of solutions with highly osmotic effect. It goes without saying that these conditions represent risks especially if one considers that the candidates for this type of intervention very often are senile persons with prearious cardiovascular equilibrium, with insufficient renal function and with insufficient arterial cerebral circulation. These are some of the problems which are to be discussed.

    2009-03-01

    Full Text Available "nThe response of living tissues to the surgical trauma is associated with varying degrees of tissue repair and involves two distinct processes including replacement and regeneration. Replacement results in scar tissue formation instead of restoration of the normal architecture. However, regeneration leads to restoration of the original architecture leaving no sign of injury. Anti-proliferative agents are used to inhibit tissue responses to surgical trauma. Among them mitomycin- C and 5- FU had gained increasing applications in ophthalmic surgeries, including filtering glaucoma surgeries, laser vision correction with excimer laser by ablative surface refractive surgery, reconstructive surgeries for ocular surface disorders and removal of neoplastic tissues and secondary operations on nasolacrimal ducts. In this review article, the various aspects of applications of these agents including their mechanism of action, function, mode of application and complications in different ophthalmology fields are discussed.

    The scale and variables linked to bariatric surgery's effect on dyslipidemia have not been conclusive. To compare the effect of Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and adjustable gastric banding (LAGB) on dyslipidemia SETTING: National bariatric surgery registry. Plasma lipids and associated variables were compared at baseline and 1 year (12±4 mo) after surgery for registry patients with dyslipidemia enrolled from June 2013 to August 2014. The greatest mean total-cholesterol (TC) reduction was observed post-RYGB, 226.7±26.4 to 181.3±30.9 mg/dL (19.9%, n = 208), followed by post-SG, 227.9±24.4 to 206.7±34.2 mg/dL (8.9%, n = 1515; P<.001). Normal TC levels of below 200 mg/dL were achieved by 76% post-RYGB patients compared with 43.5% post-SG patients (odds ratio [OR] = 6.24, 95% confidence interval [CI]: 3.69-10.53) and 25.6% post-LABG patients (OR = 9.66, 95% CI: 4.11-22.67; P<.01). Although equivalent patterns were observed for low-density-lipoprotein cholesterol (LDL), the levels of high-density-lipoprotein cholesterol (HDL) were most improved post-SG, reaching normal levels in 58.1% of SG male patients versus 39.5% of RYGB male patients (OR = 1.56, 95% CI: 1.04-2.35), (P = .02). The lowering of triglyceride levels by approximately 75% was comparable after SG and RYGB procedures. The type of surgery was the strongest independent predictor for all lipid level improvements or remissions. Male sex was an independent predictor for LDL normalization only (OR = 1.88, 95% CI: 1.24-2.85). Excess weight loss offered no meaningful prediction for lipid improvement (OR = 1.01-1.03). Particular types of bariatric surgeries had different effects on dyslipidemia, independent of weight loss. Overall, the RYGB achieved the biggest reduction in plasma lipids (TC and LDL), although SG did affect HDL. Our results could aid in the decision-making process regarding the most appropriate procedure for patients with dyslipidemia. Copyright © 2017 American

    Patient safety is an international public health priority. Ophthalmology scientific societies and organisations have intensified their efforts in this field. As a tool to learn from errors, these efforts have been linked to the management of medical professional liability insurance through the analysis of claims. A review is performed on the improvements in patient safety, as well as professional liability issues in Ophthalmology. There is a high frequency of claims and risk of economic reparation of damage in the event of a claim in Ophthalmology. Special complaints, such as wrong surgery or lack of information, have a high risk of financial compensation and need strong efforts to prevent these potentially avoidable events. Studies focused on pathologies or specific procedures provide information of special interest to sub-specialists. The specialist in Ophthalmology, like any other doctor, is subject to the current legal provisions and appropriate mandatory training in the medical-legal aspects of health care is essential. 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, and help in increasing patient safety. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    Full Text Available AIM: To report the indications for and techniques of corneal transplantation at Vietnam National Institute of Ophthalmology (VNIO over a period of 12y (2002-2013. METHODS: Records of patients who had undergone corneal transplantation at VNIO from January 1, 2002 to January 1, 2014 were reviewed to determine the indication for and type of corneal transplant performed. Patient age, gender, indication for corneal transplantation and surgical technique were recorded and analyzed. RESULTS: Corneal transplantation were underwent in 1390 eyes of 1278 patients with a mean age of 44.9±18.1y during the period under review. The most common indication was infectious corneal ulcer (n=670; 48.2%, followed by corneal scar (n=333, 24.0%, corneal dystrophy (n=138, 9.9% and failed graft (n=112, 8.1%. Nearly all procedures performed were penetrating keratoplasty (n=1300, 93.5%, with a few lamellar keratoplasty procedures performed: lamellar keratoplasty (n=52, 3.7%, Descemet’s stripping automated endothelial keratoplasty (n=27, 1.9% and deep anterior lamellar keratoplasty (n=11, 0.8%. CONCLUSION: While the most common indication for keratoplasty was infectious keratitis, nearly all indications for corneal transplantation were managed with penetrating keratoplasty. However, lamellar keratoplasty techniques, including deep anterior lamellar keratoplasty and Descemet’s stripping automated endothelial keratoplasty, are being performed with increasing frequency for isolated stromal and endothelial disorders, respectively.

    2013-07-01

    Full Text Available Dental treatment performed in patients receiving oral anticoagulant drug therapy is becoming increasingly common in dental offices.The aim of oral anticoagulant therapy is to reduce blood coagulability to an optimal therapeutic range within which the patient is provided some degree of protection from thromboembolic events. This is achieved at the cost of a minor risk of haemorrhage. Frequently raised questions concern the safety and efficacy of the various anticoagulation regimens and their accompanying thromboembolic and bleeding risks relative to invasive dental procedures.The aim of this literature review is to evaluate the available evidence on the impact of anticoagulant medications on dental treatment and highlight certain patient management issues closely interrelated to various aspects of dental treatment. For that purpose literature search in the electronic database of Medscape, Pubmed-Medline, Science Direct, and EBSCO host, in the data base of Medical University Plovdiv and specialised published books in general medicine and dentistry was made.A total of 33 publications between 1995 and 2013 were identified: 12 review articles, 11 randomized controlled and non-randomised studies, 6 guidelines and practical guides, 1 meta-analysis and 3 specialised books.

  19. Surgical procedure for limbal dermoid and palpebral coloboma-dermoid in English bulldog puppy

    Directory of Open Access Journals (Sweden)

    Božinović Stanko

    2009-01-01

    Full Text Available A dermoid is a malformation, a congenital choristoma, in fact an ectopic part of the skin. This malformation can be located on the eyelids (palpebral, on the palpebral or bulbar part of the conjunctive, on the third eyelid or on the cornea, the limbus edge of the eyelid. Ocular dermoids consist of a cornified squamous-stratified epithelium that can be pigmented to various degrees, located on irregular dermis in which there are hair follicles, sweat and fat glands, and, in rare cases, cartilage and bone can also be observed. Corneal dermoids can be classified into three types: limbal or epibulbar dermoid, a dermoid which covers the greater part or the entire cornea, a dermoid that covers the entire front segment of the eye. Coloboma presents a congenital malformation that is characterized by the absence of an eyelid and it can be located on the upper or on the lower lid. This paper presents the case of an English bulldog puppy in which a limbal dermoid and a palpebral coloboma-dermoid were observed at the same time. In this case, superficial keratectomy was selected for the treatment of the limbal dermoid, while the palpebral colobomadermoid was treated using excision with a plastic reconstruction procedure. A microscopic examination of sample tissue of the corneal demoid showed, on the surface, cornified squamous-stratified epithelium lying on the dermis. The dermis was observed to contain hair follicles, as well as sweat and fat glands.

    The objective of this study was to evaluate an Er:YAG laser (ErL) application for periodontal regenerative surgery in angular bone defects at nine sites in six patients. Debridement was thoroughly performed using a combination of curettage with a Gracey-type curette and ErL irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile saline spray. After applying an enamel matrix derivative and autogenous bone grafting, ErL was used to form a blood clot coagulation on the grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for approximately 30 seconds. Twelve months after surgery the mean probing depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had improved from (+) to (-). Mean intrabony defect depth decreased from 6.0 mm before surgery to 1.0 mm 12 months after surgery. A novel procedure for periodontal regenerative surgery applying ErL irradiation for thorough decontamination during debridement as well as blood coagulation following autogenous bone grafting seems to have achieved favorable and stable healing of periodontal pockets with significant clinical improvement and desirable regeneration of angular bone defects, including one-wall defects.

  1. Management of the temporomandibular joint in inflammatory arthritis: Involvement of surgical procedures

    2017-01-01

    Many conditions may affect the temporomandibular joint (TMJ), but its incidence in individual joint diseases is low. However, inflammatory arthropathies, particularly rheumatoid and psoriatic arthritis and ankylosing spondylitis, appear to have a propensity for affecting the joint. Symptoms include pain, restriction in mouth opening, locking, and noises, which together can lead to significant impairment. Jaw rest, a soft diet, a bite splint, and medical therapy, including disease-modifying antirheumatic drugs (DMARDs) and simple analgesia, are the bedrock of initial treatment and will improve most symptoms in most patients. Symptom deterioration does not necessarily follow disease progression, but when it does, TMJ arthroscopy and arthrocentesis can help modulate pain, increase mouth opening, and relieve locking. These minimally invasive procedures have few complications and can be repeated. Operations to repair or remove a damaged intra-articular disc or to refine joint anatomy are used in select cases. Total TMJ replacement is reserved for patients where joint collapse or fusion has occurred or in whom other treatments have failed to provide adequate symptomatic control. It yields excellent outcomes and is approved by the National Institute of Health and Care Excellence (NICE), UK. Knowledge of the assessment and treatment of the TMJ, which differs from other joints affected by inflammatory arthritis due to its unique anatomy and function, is not widespread outside of the field of oral and maxillofacial surgery. The aim of this article is to highlight the peculiarities of TMJ disease secondary to rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis and how to best manage these ailments, which should help guide when referral to a specialist TMJ surgeon is appropriate.

    For efficient utilization of operating rooms (ORs), accurate schedules of assigned block time and sequences of patient cases need to be made. The quality of these planning tools is dependent on the accurate prediction of total procedure time (TPT) per case. In this paper, we attempt to improve the accuracy of TPT predictions by using linear regression models based on estimated surgeon-controlled time (eSCT) and other variables relevant to TPT. We extracted data from a Dutch benchmarking database of all surgeries performed in six academic hospitals in The Netherlands from 2012 till 2016. The final dataset consisted of 79,983 records, describing 199,772 h of total OR time. Potential predictors of TPT that were included in the subsequent analysis were eSCT, patient age, type of operation, American Society of Anesthesiologists (ASA) physical status classification, and type of anesthesia used. First, we computed the predicted TPT based on a previously described fixed ratio model for each record, multiplying eSCT by 1.33. This number is based on the research performed by van Veen-Berkx et al., which showed that 33% of SCT is generally a good approximation of anesthesia-controlled time (ACT). We then systematically tested all possible linear regression models to predict TPT using eSCT in combination with the other available independent variables. In addition, all regression models were again tested without eSCT as a predictor to predict ACT separately (which leads to TPT by adding SCT). TPT was most accurately predicted using a linear regression model based on the independent variables eSCT, type of operation, ASA classification, and type of anesthesia. This model performed significantly better than the fixed ratio model and the method of predicting ACT separately. Making use of these more accurate predictions in planning and sequencing algorithms may enable an increase in utilization of ORs, leading to significant financial and productivity related benefits.

    2012-01-31

    BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

    Future ophthalmologists will need to have broad skills to thrive in complex health care organizations. However, training for ophthalmologists does not take advantage of all of the postgraduate years (PGYs). Although the traditional residency years seem to have little excess capacity, enhancing the internship year does offer an opportunity to expand the time for ophthalmology training in the same 4 PGYs. Integrating the internship year into residency would allow control of all of the PGYs, allowing our profession to optimize training for ophthalmology. In this white paper, we propose that we could capture an additional 6 months of training time by integrating basic ophthalmology training into the intern year. This would allow 6 additional months to expand training in areas such as quality improvement or time for "mini-fellowships" to allow graduates to develop a deeper set of skills.

    To investigate residents' self-reported satisfaction level with their proficiency in extracapsular cataract extraction (ECCE) surgery and the initial barriers to learning the procedure. This is a single-centre prospective descriptive case series involving eight first-year ophthalmology residents in Singapore National Eye Center. We recorded the demographics, frequency of review by the residents of their own surgical videos and their satisfaction level with their proficiency at each of the ECCE steps using a 5-point Likert scale. All ECCE surgical videos between October 2013 and May 2014 were collected and analysed for the overall time taken for the surgery and the time taken to perform the individual steps of the procedure. The mean age of the residents was 27.6 ± 1.5 years and 62.5% (5/8) were women. More than half (62.5%, 5/8) reviewed their own surgical videos while 37.5% (3/8) discussed the surgical videos with their peers or supervisors. Of the ECCE steps, the residents were most dissatisfied with their proficiency in performing irrigation and aspiration (87.5%, 7/8), followed by suturing (62.5%, 5/8), intraocular lens insertion (62.5%, 5/8) and tin can capsulotomy (62.5%, 5/8). The average time taken for each ECCE case was 55.0 ± 12.2 min and, of all the steps, most time was spent on suturing (20.5 ± 6.8 min), followed by irrigation and aspiration (5.5 ± 3.6 min) and tin can capsulotomy (3.3 ± 1.8 min). The first-year ophthalmology residents were most dissatisfied with their proficiency in irrigation/aspiration, suturing and tin can capsulotomy. More training needs to be directed to these areas during teaching sessions in the operating room, wet laboratory or cataract simulation training sessions.

    2016-10-01

    Perioperative vision loss is a rare complication of orthopaedic surgery and has been documented after spine, knee, hip, and shoulder procedures. It is associated with several ophthalmologic diagnoses, most commonly ischemic optic neuropathy. Although the pathophysiology remains unclear, current evidence suggests that systemic hemodynamic compromise and altered balance of intraocular perfusion contribute to the development of ischemic optic neuropathy. Although vision recovery has been reported, the prognosis of perioperative vision loss is poor, and no proven effective treatment is available. Perioperative vision loss is unpredictable and can occur in healthy patients. Associated risk factors include pediatric or elderly age, male sex, obesity, anemia, hypotension or hypertension, perioperative blood loss, prolonged surgical time, and prone positioning. Preventive strategies include avoiding direct pressure to the eye, elevating the head, optimizing perioperative hemodynamic status, and minimizing surgical time with staged surgical procedures as appropriate.

    Full Text Available INTRODUCTION: This analysis explores the association between elements of surgical efficiency in voluntary medical male circumcision (VMMC, quality of surgical technique, and the amount of time required to conduct VMMC procedures in actual field settings. Efficiency outcomes are defined in terms of the primary provider's time with the client (PPTC and total elapsed operating time (TEOT. METHODS: Two serial cross-sectional surveys of VMMC sites were conducted in Kenya, Republic of South Africa, Tanzania and Zimbabwe in 2011 and 2012. Trained clinicians observed quality of surgical technique and timed 9 steps in the VMMC procedure. Four elements of efficiency (task-shifting, task-sharing [of suturing], rotation among multiple surgical beds, and use of electrocautery and quality of surgical technique were assessed as explanatory variables. Mann Whitney and Kruskal Wallis tests were used in the bivariate analysis and linear regression models for the multivariate analyses to test the relationship between these five explanatory variables and two outcomes: PPTC and TEOT. The VMMC procedure TEOT and PPTC averaged 23-25 minutes and 6-15 minutes, respectively, across the four countries and two years. The data showed time savings from task-sharing in suturing and use of electrocautery in South Africa and Zimbabwe (where task-shifting is not authorized. After adjusting for confounders, results demonstrated that having a secondary provider complete suturing and use of electrocautery reduced PPTC. Factors related to TEOT varied by country and year, but task-sharing of suturing and/or electrocautery were significant in two countries. Quality of surgical technique was not significantly related to PPTC or TEOT, except for South Africa in 2012 where higher quality was associated with lower TEOT. CONCLUSIONS: SYMMACS data confirm the efficiency benefits of task-sharing of suturing and use of electrocautery for decreasing TEOT. Reduced TEOT and PPTC in high volume

    Full Text Available Purpose: To test whether there is an association between the growth in the number of ophthalmic journals in the past years and their mean and maximum impact factor (IF as a common sign of scientific proliferation. Methods: Using data from the 2013 Journal Citation Report database a study of the major clinical medical fields was conducted to assess the correlation between the number of journals and maximum IF in a given field in the year 2013. In the field of ophthalmology, we examined the correlation between year, number of journals, mean IF and maximum IF in the field of ophthalmology throughout the years 2000–2013. Results: In the major medical fields, a positive correlation was found between the number of journals and the maximum IF (quadratic R2 = 0.71, P< 0.001. When studying the field of ophthalmology a positive correlation between the number of journals and mean IF (R2 = 0.84, P< 0.001 and between number of journals and maximum IF (R2 = 0.71, P< 0.001 was detected. Conclusions: Our findings suggest that the variation in the IF can be explained by the number of journals in the field of ophthalmology. In the future, the formation of additional ophthalmology journals is likely to further increase the IFs of existing journals.

    Neuro-ophthalmology is a medical subspecialty concerned on the nervous system diseases with ocular manifestations, this could be both sensory and motor, including ocular movements, papillary responses, and the structure changes of the brain and nervous system with ocular manifestations. Although neuro-ophthalmology in China has achieved some progress, certain problems still exist, such as the professional neuro-ophthalmology team and related academic organization are still absent in China; neuro-ophthalmology knowledge has not been popularized; the new technologies for diagnosis and treatment in neuro-ophthalmology have not been absorbed and applied; the coordination and cooperation with other related disciplines are not enough. We should actively promote the development of neuro-ophthalmology in China, including organization of a professional team of neuro-ophthalmology, popularization of neuro-ophthalmology knowledge to the ophthalmologists, development of research work in neuro-ophthalmology and the collaboration with international neuro-ophthalmologists.

  16. CHANGES OF INTERLEUKIN-6 AND RELATED FACTORS AS WELL AS GASTRIC INTRAMUCOSAL Ph DURING COLORECTAL AND ORTHOPAEDIC SURGICAL PROCEDURES

    2006-01-01

    Objective To investigate the changes of perioperative serum levels of interleukin-6 ( IL-6), C-reactive protein (CRP), and cortisol, as well as gastric intramucosal pH (pHi) and plasma lactate, aiming to compare systemic changes and tissue perfusion during colorectal and orthopaedic surgical procedures. Methods Twenty patients were randomly assigned to two groups, 10 cases of operation on vertebral canal, 10 cases of colorectal radical operation. Venous blood was drawn at 1 day before operation, 2, 4, and 6 hours following skin incision, and 1 day after operation, in order to measure serum IL-6, CRP, and cortisol, pHi and plasma lactate were also measured at the same time points. Results Serum concentrations of IL-6 and cortisol increased gradually following operation, reaching the peak value at 6 hours from the beginning of operation. CRP was not detectable until the first day after operation. Peak concentration of IL-6 had positive relationship with CRP. These variables changed more significantly in colorectal group than that in orthopaedic group (P < 0. 05). pHi decreased gradually, reaching the lowest level at 4 hours from the beginning of operation, and to more extent in colorectal group than that in orthopaedic group ( P < 0. 05 ).Conclusion IL-6 may reflect tissue damage more sensitively than CRP. Colorectal surgery might induce systemic disorder to more extent, in terms of immuno-endocrinal aspect as well as tissue perfusion, reflected with pHi.

    Although the benefit of surgical ablation for atrial fibrillation (AF) performed concomitant to mitral valve surgery is established, whether that performed concomitant to non-mitral cardiac surgery is beneficial remains unclear. In non-mitral, non-left-atriotomy cardiac surgery, the optimal surgical approach for AF remains to be established. Therefore, using the Japan Adult Cardiovascular Surgery Database (JACVSD), we compared 2 surgical ablation procedures [the maze procedure and pulmonary vein isolation (PVI)] performed concomitant to non-mitral cardiac surgery. Of 3402 JACVSD patients who had undergone elective non-mitral cardiac surgery by 2012, 1797 (53%) had undergone concomitant PVI, and 1339 (39%) had undergone the maze procedure. To compensate for patient heterogeneity, we conducted a propensity score-matched analysis of 1952 patients who had undergone PVI or the maze procedure (976 patients each). Operative procedures took significantly longer in the Maze Group. Although postoperative AF occurred in 34.3% of the PVI Group patients and in 31.9% of the Maze Group patients (p = 0.371), the incidence of first-time pacemaker implantation was significantly lower in the PVI Group (1.9 vs. 4.1%, respectively; p = 0.005). There was no significant difference in other morbidities or in operative mortality. Postoperative hospital and ICU stays tended to be longer in the Maze Group. Our data indicate that surgical ablation of AF concomitant to non-mitral cardiac surgery is beneficial. Furthermore, PVI and the maze procedure appear to be of equal benefit in this context, except that the maze procedure may more frequently result in the need for pacemaker implantation.

    Full Text Available The problem of restricted availability and quality of ophthalmologic medical care remains one of the main ones in the national healthcare. The article gives a comparative analysis of the opinions of rural residents of Leningrad region are in need of surgical treatment for ophthalmologic diseases, availability and quality of specialized medical care. A questionnaire was developed based on the methodology proposed by the Federal compulsory medical insurance Fund, through formal interviews of respondents of patients who received specialized ophthalmologic medical care in Leningrad region before opening of eye care hospitals for surgical treatment of cataract and glaucoma (148 patients and afterwards (320 patients. The results show that almost all patients who received treatment after the modernization of ophthalmologic offices are satisfied with the quality of medical care (completely satisfied – 91,3 %, quite satisfied – 7,6 %, which is significantly higher than the figures obtained in the survey of the patients before creation of specialized departments (t=3,6, p<0.05. Availability of medical care before reequipment of ophthalmologic departments in hospitals satisfied 62.8 % of respondents, and after the organization of activities of eye care hospitals – 75, 3 % (t=2,8, p<0.05. However, despite the new form of organization of medical aid, 27.5 % of the respondents are still not satisfied with its transport accessibility. Thus, patients receiving operative treatment of cataract are generally satisfied with the availability and quality of their medical services. Higher ratings of availability and quality of specialized eye medical care were received after opening of eye care hospitals for surgical treatment of cataract and glaucoma in Leningrad region.

    The African Institute of Tropical Ophthalmology (AITO) is an OCCCMED institute, founded in Bamako in 1953. The OCCCMED itself is based at Bobo Dioulasso (Burkina Faso). AITO is a WHO collaborating center for the prevention of blindness. Training is one of the main activities of the institute, along with eye care, research and assessment. The prevalence of blindness in sub-Saharan countries is about 1.2%, with blindness mostly caused by cataracts, trachoma, glaucoma and onchocercosis. The demand for eye care is high but there are currently too few trained personnel to satisfy that demand. Therefore, AITO's role in training eye-care professionals is particularly important. The institute trains ophthalmologists, specialist nurses, eye surgeons (who remove cataracts) and spectacle manufacturers. Training is carried out within the framework of the community and apprenticeship in the workplace. The student must attain specific targets, listed in a "competency passport" issued at the start of training. Clinical and surgical ophthalmology and general eye care are taught. Training costs and grants are mostly paid by the Lions Club International Sight First Program or by the French Overseas Development Ministry. Since 1991, AITO has trained to graduation: 18 ophthalmologists; 24 eye surgeons; 83 specialist nurses; 16 spectacle manufacturers.

    The purpose of this study was to assess for compounded risk of postoperative morbidity with the addition of a simultaneous contralateral breast matching procedure at the time of mastectomy and immediate breast reconstruction. 2005 to 2012 American College of Surgeons National Surgical Quality Improvement Program databases were used to identify cases of mastectomy and immediate breast reconstruction with and without simultaneous contralateral breast matching procedures. Matching procedures included mastopexy, reduction mammaplasty, and augmentation mammaplasty. Thirty-day postoperative morbidity was assessed using univariable and multivariable logistic regression. Of 59,766 mastectomy patients, 24,191 (40 percent) underwent immediate breast reconstruction: 903 (3.7 percent) underwent matching procedures and 23,288 (96.3 percent) did not. Univariable logistic regression demonstrated that the matching procedure group had statistically significantly higher overall morbidity (OR, 1.288; 95 percent CI, 1.022 to 1.623; p = 0.032). Although surgical and systemic morbidity did not differ significantly, the matching procedure group demonstrated higher risk for superficial surgical-site infection (OR, 1.57; 95 percent CI, 1.066 to 2.31; p = 0.022), reconstruction failure (OR, 1.69; 95 percent CI, 1.014 to 2.814; p = 0.044), and pulmonary embolism (OR, 2.54; 95 percent CI, 1.01 to 6.37; p = 0.048). Controlling for possible confounders, multivariable logistic regression rendered the relationship between matching procedure and complications insignificant (OR, 1.17; 95 percent CI, 0.92 to 1.48; p = 0.2). These data suggest that preoperative comorbidities and other patient-related factors may have a larger influence on postoperative morbidity than the addition of a contralateral matching procedure alone.

    This retrospective study analyzed the pool of patients referred for treatment with dental implants over a 3-year period in a referral specialty clinic. All patients receiving dental implants between 2002 and 2004 in the Department of Oral Surgery and Stomatology, University of Bern, were included in this retrospective study. Patients were analyzed according to age, gender, indications for implant therapy, location of implants, and type and length of implants placed. A cumulative logistic regression analysis was performed to identify and analyze potential risk factors for complications or failures. A total of 1,206 patients received 1,817 dental implants. The group comprised 573 men and 633 women with a mean age of 55.2 years. Almost 60% of patients were age 50 or older. The most frequent indication for implant therapy was single-tooth replacement in the maxilla (522 implants or 28.7%). A total of 726 implants (40%) were inserted in the esthetically demanding region of the anterior maxilla. For 939 implants (51.7%), additional bone-augmentation procedures were required. Of these, ridge augmentation with guided bone regeneration was performed more frequently than sinus grafting. Thirteen complications leading to early failures were recorded, resulting in an early failure rate of 0.7%. The regression analysis failed to identify statistically significant failure etiologies for the variables assessed. From this study it can be concluded that patients referred to a specialty clinic for implant placement were more likely to be partially edentulous and over 50 years old. Single-tooth replacement was the most frequent indication (> 50%). Similarly, additional bone augmentation was indicated in more than 50% of cases. Adhering to strict patient selection criteria and a standardized surgical protocol, an early failure rate of 0.7% was experienced in this study population.

    Our goal was to estimate the performance statistics of an electronic surveillance system for surgical site infections (SSIs), generally applicable in French hospitals. Three detection algorithms using 2 different data sources were tested retrospectively on 9 types of surgical procedures performed between January 2010 and December 2011 in the University Hospital of Nantes. The first algorithm was based on administrative codes, the second was based on bacteriological data, and the third used both data sources. For each algorithm, sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated. The reference method was the hospital's routine surveillance: a comprehensive review of the computerized medical charts of the patients who underwent one of the targeted procedures during the study period. A 3,000-bed teaching hospital in western France. We analyzed 4,400 targeted surgical procedures. Sensitivity results varied significantly between the three algorithms, from 25% (95% confidence interval, 17-33) when using only administrative codes to 87% (80%-93%) with the bacteriological data and 90% (85%-96%) with the combined algorithm. Fewer variations were observed for specificity (91%-98%), PPV (21%-25%), and NPV (98% to nearly 100%). Overall, performance statistics were higher for deep SSIs than for superficial infections. A reliable computer-enhanced SSI surveillance can easily be implemented in French hospitals using common data sources. This should allow infection control professionals to spend more time on prevention and education duties. However, a multicenter study should be conducted to assess the generalizability of this method.

AIM To evaluate the results of LIFT procedure in selective fistula patients to know its effectiveness in the management of fistulain-ano. METHODS 12 patients who underwent this procedure were evaluated. This prospective study was conducted over a period of one year after careful selection of patients with transsphincteric fistula with fixed inclusion and exclusion criteria. RESULTS Out of 12 patients, 10 patients were male and 2 were female. The mean age was 38.6 years. Of these, 9 patients were healed completely without any complications. One patient developed abscess which was drained later. One patient required additional procedure in the form of simple fistulotomy. One patient developed transient flatus incontinence which subsided later. One patient developed recurrence in 6 months. CONCLUSION This analysis indicates that the LIFT procedure is primarily effective for transsphincteric fistula patients with an overall fistula closure of 91.66% with low impact of sphincter damage and recurrence rate of 8.33%.

    To test whether there is an association between the growth in the number of ophthalmic journals in the past years and their mean and maximum impact factor (IF) as a common sign of scientific proliferation. Using data from the 2013 Journal Citation Report database a study of the major clinical medical fields was conducted to assess the correlation between the number of journals and maximum IF in a given field in the year 2013. In the field of ophthalmology, we examined the correlation between year, number of journals, mean IF and maximum IF in the field of ophthalmology throughout the years 2000-2013. In the major medical fields, a positive correlation was found between the number of journals and the maximum IF (quadratic R2 = 0.71, Pjournals and mean IF (R2 = 0.84, Pjournals and maximum IF (R2 = 0.71, Pjournals in the field of ophthalmology. In the future, the formation of additional ophthalmology journals is likely to further increase the IFs of existing journals.

    To determine the impact of surgical site infections (SSIs) on health care costs following common ambulatory surgical procedures throughout the cost distribution. Data on costs of SSIs following ambulatory surgery are sparse, particularly variation beyond just mean costs. We performed a retrospective cohort study of persons undergoing cholecystectomy, breast-conserving surgery, anterior cruciate ligament reconstruction, and hernia repair from December 31, 2004 to December 31, 2010 using commercial insurer claims data. SSIs within 90 days post-procedure were identified; infections during a hospitalization or requiring surgery were considered serious. We used quantile regression, controlling for patient, operative, and postoperative factors to examine the impact of SSIs on 180-day health care costs throughout the cost distribution. The incidence of serious and nonserious SSIs was 0.8% and 0.2%, respectively, after 21,062 anterior cruciate ligament reconstruction, 0.5% and 0.3% after 57,750 cholecystectomy, 0.6% and 0.5% after 60,681 hernia, and 0.8% and 0.8% after 42,489 breast-conserving surgery procedures. Serious SSIs were associated with significantly higher costs than nonserious SSIs for all 4 procedures throughout the cost distribution. The attributable cost of serious SSIs increased for both cholecystectomy and hernia repair as the quantile of total costs increased ($38,410 for cholecystectomy with serious SSI vs no SSI at the 70th percentile of costs, up to $89,371 at the 90th percentile). SSIs, particularly serious infections resulting in hospitalization or surgical treatment, were associated with significantly increased health care costs after 4 common surgical procedures. Quantile regression illustrated the differential effect of serious SSIs on health care costs at the upper end of the cost distribution.

    Summary The development of analgesic interventions in paediatric surgical patients is often limited by the inherent difficulties of conducting large randomized clinical trials to test interventions in those patients. Regional anaesthesia is a valid strategy to improve postoperative pain in the adult surgical population, but the effects of regional anaesthesia on postoperative pain outcomes in paediatric patients are currently not well defined. The main objective of the current review was to systematically evaluate the use of regional anaesthesia techniques to minimize postoperative pain in paediatric patients. A systematic search was performed to identify randomized controlled trials that evaluated the effects of the regional anaesthesia techniques on postoperative pain outcomes in paediatric surgical patients' procedures. Seventy-three studies on 5125 paediatric patients were evaluated. Only few surgical procedures had more than one small randomized controlled trial favouring the use of regional anaesthesia to minimize postoperative pain (ophthalmological surgery, cleft lip repair, inguinal hernia, and urological procedures). Additional evidence is required to support the use of specific regional anaesthesia techniques to improve postoperative pain for several surgical procedures (craniectomy, adenotonsillectomy, appendectomy, cardiac surgery, umbilical hernia repair, upper and lower extremity) in paediatric patients. Currently, only a very limited number of regional anaesthesia techniques have demonstrated significant improvement on postoperative pain outcomes for a restricted number of surgical procedures. More studies are needed in order to establish regional anaesthesia as a valid strategy to improve analgesia in the paediatric surgical population.

    Several plants have been found to have effective against number of ophthalmological problems in Navarra. Information was collected using semi-structured ethnobotanical interviews with 686 informants in 267 locations. In order to confirm the pharmacological application of the uses more cited by the informants, a literature review was conducted. A total of 57 pharmaceutical uses were reported, for 19 plants and 13 families, mainly represented by Asteraceae. The most frequently used parts were inflorescences, flowers, aerial parts, leaves and flowered aerial parts. The related affections fell into eleven categories: bloodshot eyes, watery eyes and wounds, improve vision, irrited eyelids, rheums and styes, tired eyes, conjunctivitis, eyewash, ocular problems in general. The most cited plants were: Chamaemelum nobile (L.) All., Santolina chamaecyparissus L. ssp. squarrosa (DC.) Nyman, Sambucus nigra L. ssp. nigra, Rosa agrestis Savi and Calendula officinalis L. None of them have been pharmacologically validated by Official International Organisms. From the therapeutic point of view, Allium sativum L., Foeniculum vulgare Mill., C. officinalis, and S. chamaecyparissus ssp. squarrosa deserve special attention, because ethnobotanical and pharmacological studies suggest that these medicinal plants are effective for ophthalmological problems. The present study constitutes a good basis for further phytochemical and pharmacological research of these four plants, which could be of interest in the design of new inexpensive, effective and safe drugs. The remaining plants are needed to be screened through standard pharmacological and clinical procedures for their activities. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    AIM: To determine factors affecting the outcome of patients with cirrhosis undergoing surgery and to compare the capacities of the Child-Turcotte-Pugh (CTP) and model for end-stage liver disease (MELD) score to predict that outcome.METHODS: We reviewed the charts of 195 patients with cirrhosis who underwent surgery at two teaching hospitals over a five-year period. The combined endpoint of death or hepatic decompensation was considered to be the primary endpoint.RESULTS: Patients who reached the endpoint had a higher MELD score, a higher CTP score and were more likely to have undergone an urgent procedure. Among patients undergoing elective surgical procedures, no statistically significant difference was noted in the mean MELD (12.8 ± 3.9 vs 12.6 ± 4.7, P = 0.9) or in the mean CTP (7.6 ± 1.2 vs 7.7 ± 1.7, P = 0.8) between patients who reached the endpoint and those who did not. Both mean scores were higher in the patients reaching the endpoint in the case of urgent procedures (MELD: 22.4 ± 8.7 vs 15.2 ± 6.4, P = 0.0007; CTP: 9.9 ± 1.8 vs 8.5 ± 1.8, P = 0.008). The performances of the MELD and CTP scores in predicting the outcome of urgent surgery were only fair, without a significant difference between them (AUC = 0.755 ± 0.066 for MELD vs AUC = 0.696 ± 0.070 for CTP, P = 0.3).CONCLUSION: The CTP and MELD scores performed equally, but only fairly in predicting the outcome of urgent surgical procedures. Larger studies are needed to better define the factors capable of predicting the outcome of elective surgical procedures in patients with cirrhosis.

    Full Text Available BACKGROUND & AIM During Nitrous Oxide+ Oxygen anaesthesia and during laparoscopic surgeries using carbon dioxide for creating pneumoperitoneum, if cuff of endotracheal tube is inflated with air, cuff pressure can rise to dangerous limits and it can produce ischemia of tracheal mucosa. Hence distilled water as an alternative agent to air for inflation of cuffs of endotracheal tubes was used for our study. Our aim is to investigate the difference in increase of intra-cuff pressure with time during laparoscopic surgical procedures under general endotracheal anaesthesia with Nitrous oxide+ Oxygen+ relaxant technique when cuffs of endotracheal tube were inflated by air & distilled water. METHODS Fifty patients (n=50 undergoing different laparoscopic surgical procedures under general endotracheal anaesthesia were randomly divided into 2 groups. In group A, air was used & in group D, distilled water was used to inflate the cuffs of endotracheal tubes. General anaesthesia was given with Nitrous oxide+ Oxygen+ relaxant technique. The intra-cuff pressures of endotracheal tube cuffs were recorded in the beginning and at the end of laparoscopic surgical procedures. Increase of pressures with time were recorded and analysed. RESULTS In group in whom we inflated the cuffs with air, there was a significant increase in intra-cuff pressures with time and there was definite diffusion of gases into the cuffs. Increase of pressure with time was statistically highly significant (P=0.00001. But in group in whom we used distilled water to inflate the cuffs, there was no change in the volume of water used for inflation and water came out of cuffs at the end of the laparoscopic surgical procedures. No additional air could be aspirated from the cuffs at the end of laparoscopic surgeries in distilled water group, indicating that there was no diffusion of gases into the cuffs or the gases diffused got dissolved in distilled water. Hence there was no increase of volume

    Full Text Available Bevacizumab is a full-length, humanized monoclonal antibody directed against all the biologically active isoforms of vascular endothelial growth factor (VEGF-A. The antibody was initially designed and studied as an anti-angiogenic strategy to treat a variety of solid tumors. After approval by the US Food and Drug Administration, bevacizumab gained access into ophthalmology to treat various types of neovascular diseases. Since the first report in 2005 more than 100 publications share the experience with bevacizumab in ophthalmology. Two authors independently assessed the research results from Pubmed to April 2007. The reference list is a selection of key publications related to the issue. Currently, there is no well-designed randomized controlled trial yet to establish the efficacy and safety of intraocular bevacizumab for any ocular disease in spite of its assumed characteristics representing the most cost-effective VEGF inhibitor.

    Research on the field of organizational ethics to investigate to which extent ophthalmologic clinics, inserted in the competitive atmosphere, in the condition of organizations in search of survival, subordinate ethics to competitiveness in the managerial praxis, that is, in the administrative sphere. Kohlberg is taken as theoretical reference, approaching the theme of ethical subordination to competitiveness. The instrument to evaluate moral behaviors of organizations, elaborated by Licht, is applied. The quantitative method is used, adopting analytic instruments, such as Q of Yule and non parametric tests, when dealing with the data of 41 ophthalmologic clinics. The results of the research seem to indicate that administrators of ophthalmologic clinics of greater performance subordinate ethical principles to competitiveness, seeking to assure the survival of the company and, when confronted with the instrument to evaluate their moral behavior, proposed by Kohlberg, have a significantly smaller presence in the postconventional stage than administrators of ophthalmologic clinics with a smaller performance. One may affirm, according to non parametric tests, at the level of significance of 0.05, that the levels of moral development of the two groups differ significantly. The obtained results are according to the literature, especially concerning the "paradox of the ethical subordination and competitiveness". They also suggest that the warrant of the survival of the company tends to reduce the perception of the groups in power regarding the problems that happen in the community, and that a reduction of the ethical values subordinated to competition occurs, and such reduction provokes growing feelings of economical disputes in the social sphere.

    The prediction of the risk of a percutaneous transluminal coronary angioplasty has either been based on coronary lesion morphology or on clinical parameters, but a combined angiographic and clinical risk assessment system has not yet been evaluated prospectively. Five experienced interventionalists categorized 7,144 patients with 10,081 stenoses (1.4 lesion/patient) for both the risk and the difficulty of the procedure. Risk categories are as follows: 1 = low risk; 2 = intermediate risk; 3 = high risk. This division was made for percutaneous transluminal coronary angioplasty planning purposes. Category 1 patients denotes those in whom surgical standby is not required; category 2 patients, surgical standby not required but available within 1 hr; category 3 patients, surgical standby required. Difficulty categories are as follows: 1 = easy lesion; 2 = moderately difficult lesion; 3 = difficult lesion. Success was defined as a reduction of the degree of stenosis to less than 50%, without acute myocardial infarction, emergency redilatation, emergency bypass grafting, or death within 1 week. The procedure was not successful in difficulty category 1 in 1.6%, in category 2 in 3.5%, and in category 3 in 9.9%. Complications occurred in risk category 1 in 3.5%, in category 2 in 5.2%, and in category 3 in 12.4%. All differences were statistically significant (P < 0.05). Experienced cardiologists can well predict the risk and success of a coronary angioplasty procedure. This helps to optimize surgical standby, although even in the lowest-risk category complications can occur.

    Full Text Available Introduction: Emergency physicians are among the few specialists besides ophthalmologists who commonly perform ophthalmologic examinations using the slit lamp and other instruments. However, most medical schools in the United States do not require an ophthalmology rotation upon completion. Teaching procedural skills to medical students can be challenging due to limited resources and instructor availability. Our study assesses the effectiveness of a 40-minute hands-on teaching session on ophthalmologic examination for medical students using only two instructors and low-cost equipment. Methods: We performed an interventional study using a convenience sample of subjects. Pre- and post-workshop questionnaires on students’ confidence in performing ophthalmologic examination were administered. We used a paired t-test and Wilcoxon rank test to analyze the data. Results: Of the 30 participants in the study, the mean age was 25 and the majority were first-year medical students. The students’ confidence in performing every portion of the ophthalmologic exam increased significantly after the teaching session. We found that the average confidence level before the teaching session were below 2 on a 1-5 Likert scale (1 being the least confident. Confidence levels in using the slit lamp had the highest improvement among the skills taught (2.17 95% CI [1.84-2.49]. Students reported the least improvement in their confidence in assessing extraocular movements (0.73, 95% CI [0.30-1.71] and examining pupillary function (0.73, 95% CI [0.42-1.04]. We observed the biggest difference in median confidence level in the use of the tonometer (4 with a p-value of <0.05. Conclusion: A 40-minute structured hands-on training session can significantly improve students’ confidence levels in ophthalmologic skills.

    Smart phones are being increasingly used among health professionals. Ophthalmological applications are widely available and can turn smart phones into sophisticated medical devices. Smart phones can be useful instruments for the practice of evidence-based medicine, professional education, mobile clinical communication, patient education, disease self-management, remote patient monitoring or as powerful administrative tools. Several applications are available for different ophthalmological examinations that can assess visual acuity, color vision, astigmatism, pupil size, Amsler grid test and more. Smart phones can be useful ophthalmic devices for taking images of anterior and posterior eye segment. Professional literature and educational material for patients are easily available with use of smart phones. Smart phones can store great amount of informations and are useful for long term monitoring with caution for patient confidentiality. The use of smart phones especially as diagnostic tools is not standardized and results should be carefully considered. Innovative role of smartphone technology and its use in research, education and information sharing makes smart phones a future of ophthalmology and medicine.

    International peer-reviewed publications form the basis of evidence-based medicine and are one of the main indicators of ophthalmology research activity. This paper examines the origins of such articles in relation to geographical location, population demographics and economic research profiles. Publications from five ophthalmology journals over 5 years were analysed using the Medline/Pubmed search engine. Country of origin was ascertained based on the address of the corresponding author. Worldwide ophthalmology research output was analysed in relation to population demographics and research expenditure. In total, 7,754 articles from 67 countries from 2002 to 2006 were analysed. The overall number of articles published increased by over 29% during this period. The United States (US) produced the greatest number of articles. Singapore produced the most publications per 10(6) population. There was a relationship between gross domestic product (GDP) greater than $20,000 and population-adjusted output. The US followed by the United Kingdom and Japan were the greatest gross contributors. Population-adjusted figures revealed that Singapore, Iceland and Australia were the most prolific nations. There was a relationship between GDP and the top-ranked population-adjusted countries. The top 10 most productive population-adjusted countries spend relatively more on research and development than the top 10 gross contributors.

    Full Text Available Western medicine was first introduced to Taiwan by medical missionaries in the mid-19th century. Modernization of medicine was systematically transplanted to Taiwan in the Japanese colonial period, and ophthalmology was established third among hospital departments, following internal medicine and surgery. Dr Hidetaka Yamaguchi, an ophthalmologist, was the first head of the Taihoku Hospital, later known as National Taiwan University Hospital (NTUH; Taipei, Taiwan. Ophthalmologists during the colonial period conducted studies on tropical and infectious eye diseases. After World War II, ophthalmologists at NTUH played an important role in medical education, residency training, studies, and teaching. Dr Yan-Fei Yang established the Taiwan Ophthalmological Society in 1960 and instituted its official journal in 1962. Dr Ho-Ming Lin established the Department of Ophthalmology at the Tri-Service General Hospital in the 1950s and the Veterans General Hospital in the 1960s. Taiwan ophthalmologists eradicated trachoma by 1971. Cataract surgery and penetrating keratoplasty were initially performed in the 1960s. Currently, there are about 1600 ophthalmologists in Taiwan conducting an estimated 120,000 cataract surgeries and 600 corneal transplantations annually. Many subspecialty societies have been established recently that serve to educate Taiwanese ophthalmologists and to connect with international ophthalmic societies. Taiwan ophthalmologists continue to contribute to the advancement of ophthalmic knowledge globally.

    Full Text Available Background and Aims: This study documents a survey of final-year ophthalmology postgraduate students on the subject of their residency training. A similar survey conducted 7 years ago published in IJO had concluded that the residency program was not up to expectations in many centers. Our study aimed to see if ophthalmology training and student perceptions differed since then. Materials and Methods: For our study, we added a few questions to the same questionnaire used in the article "which is the best method to learn ophthalmology? Resident doctors′ perspective of ophthalmology training" published in IJO, Vol. 56 (5. Results: Forty-nine students (62.02% returned completed forms. Most students desired an orientation program on entering residency, and wished to undergo diagnostic training initially. Case-presentation with demonstration and Wet-lab learning were most preferred. There was a big difference between the number of surgeries students actually performed and the number they felt would have been ideal. Conclusion: On the whole, the students still felt the need for improved training across all aspects of ophthalmology.

    Karganov Mikhail

    2015-12-01

    Full Text Available The method of laser correlation spectroscopy (LCS is based on the analysis of the spectrum of quasielastic light scatter during coherent monochromatic laser irradiation of micro-particles in biological fluids (blood serum, urine, oropharyngeal washout fluid, tear fluid etc.. Spectrum provides information on dynamic processes in the analyzed system: translation motion of scattering particles and their orientation and conformation dynamics. Special procedures of cluster analysis make it possible to find out to which linkage group a particular spectrum belongs. LCS allows evaluation of sub-fractional composition of biological fluids in a wide range of molecular sizes (from 1 to 10,000 nm, which determines principal novelty of this approach in ophthalmology.

    Although theory-based schemes for course design are widely used in educational settings, making use of cognitive theory in the design of surgical skills courses in ophthalmology is rare. The primary aim of this study is to describe the application of instructional design, an established theory-based approach in course design, to the development of a surgical skills course for ophthalmology residents. The secondary aim of this study is to assess the educational effect of this theory-based course. A 1-day skills course was designed according to Gagné׳s events of instruction model, which was employed as a template for the instructional sequence of learning steps. Skills acquisition following the implementation of the model was measured with precourse and postcourse assessments. Moorfields Eye Hospital organized the 1-day annual intermediate surgical skills course, which was hosted at the Royal College of Ophthalmologists' microsurgical skills laboratory. A total of 20 ophthalmology residents of Moorfields Eye Hospital participated in the study. A 1-day surgical skills course was formulated according to the instructional design principles outlined. The 4 objectives of the course (corneal suturing, corneal gluing, intravitreal injections, and eyelid suturing) were addressed in a parallel fashion as to allow for multiple objectives to be processed simultaneously, in the context of the instructional design sequence. Assessments demonstrated significant improvement in skills acquisition for the 4 course objectives. Instructional design is a valuable tool for planning effective surgical training courses as it is portable, allowing its application to a wide variety of outcomes and settings, and its terminology is simple and understandable to those working in clinical education.

    Full Text Available Aim: The aim of the present case series report is to illustrate a clinical technique and present the application of onepiece transmucosal implants in flapless surgical procedures, supporting full arch immediate prostheses. Materials and methods: A total of 294 implants (Xive TG, Friadent, Germany have been used to support full arch immediate prostheses, over the last six years and have been in function for at least one year. The surgical placement of five or more implants per case involved immediate extraction and intrasocket flapless placement, combined with minimal flap elevation in the areas of healed extraction sites (43 mandibular and 7 maxillary arches. In all cases immediate provisionalization followed. Detailed three-dimensional cone-beam localized volumetric tomography preceeded the surgical procedures. The delivery of the final ceramo-metal prostheses was accomplished within a 20 day period. Materials and methods: Results Six implants failed to osseointegrate. All other implants are still successfully bearing the final prosthesis for the time that they have been followed. Soft tissue reaction was favorable from both the biologic and esthetic point of view. Conclusion: The flapless placement of one piece implants into edentulous healed sites is a predictable procedure in the presence of abundance of supporting bone as confirmed by 3-D imaging. On the other hand, immediate extraction placement of one piece implants allows the engagement of sound bone located deeper into the socket and provides adequate mechanical support of the soft tissue architecture that is preserved predictably. In all cases the prosthetic procedures are accomplished without disturbing the hardsoft tissue interface as the abutment-prosthesis interface is coronally elevated by the virtual design of the implant.

    We studied the effect of a 1-min hand wash on the bacterial hand flora in two consecutive surgical hand disinfection procedures. A propanol-based hand rub (PBHR; Sterillium) and n-propanol (60%, v/v) were tested in a Latin-square design according to EN 12791 in four variations. The reference alcohol was always applied for 3 min after a 1-min hand wash (variation 1). The PBHR was applied for 1.5 min (first application) or 0.5 min (second application). Variation 2 included a 1-min hand wash before both applications, variation 3 included the hand wash before application 1, in variation 4 hands were not washed at all before application. Pre- and post-values were obtained according to EN 12791. The reference disinfection reduced bacteria by 2.99 log(10) (immediate efficacy) and 2.22 log(10) after 3 h. The second reference disinfection reduced bacteria by 0.95 log(10) (immediate efficacy) and 0.68 log(10) after 3 h. The PBHR always yielded an equivalent reduction with and without a preceding hand wash (p > 0.05; Friedman test). A 1-min hand wash before application of the PBHR did not significantly change its efficacy for surgical hand disinfection in two consecutive surgical procedures of 3 h.

    Google Glass has the potential to become a ubiquitous and translational technological tool within clinical plastic surgery. Google Glass allows clinicians to remotely view patient notes, laboratory results, and imaging; training can be augmented via streamed expert master classes; and patient safety can be improved by remote advice from a senior colleague. This systematic review identified and appraised every Google Glass publication relevant to plastic surgery and describes the first plastic surgical procedures recorded using Google Glass. A systematic review was performed using PubMed National Center for Biotechnology Information, Ovid MEDLINE, and the Cochrane Central Register of Controlled Trials, following modified Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Key search terms "Google" and "Glass" identified mutually inclusive publications that were screened for inclusion. Eighty-two publications were identified, with 21 included for review. Google Glass publications were formal articles (n = 3), editorial/commentary articles (n = 7), conference proceedings (n = 1), news reports (n = 3), and online articles (n = 7). Data support Google Glass' positive impact on health care delivery, clinical training, medical documentation, and patient safety. Concerns exist regarding patient confidentiality, technical issues, and limited software. The first plastic surgical procedure performed using Google Glass was a blepharoplasty on October 29, 2013. Google Glass is an exciting translational technology with the potential to positively impact health care delivery, medical documentation, surgical training, and patient safety. Further high-quality scientific research is required to formally appraise Google Glass in the clinical setting.

    The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97

    Lower extremity acute compartment syndrome after gynecologic surgery in the lithotomy position is a rare, yet potentially devastating complication. A high level of suspicion is paramount for early recognition and mitigation of acute compartment syndrome originating from prolonged surgery in lithotomy position. A 23-year-old female, gravida 1, para 0, underwent a laparoscopic salpingectomy for a ruptured ectopic pregnancy. Surgical time was 90 min. Postoperatively, the patient developed acute compartment syndrome of both legs necessitating emergent bilateral four-compartment fasciotomies, with repeated returns to the operating room for 2nd look procedures and delayed wound closures. The patient regained full function within 3 months and returned to an unrestricted baseline activity level. Technical diligence in applying a lithotomy position is paramount for preventing postoperative lower extremity compartment syndrome. A high level of suspicion for this severe complication in conjunction with early recognition and immediate surgical management can mitigate long-term adverse sequelae and improve postoperative outcomes.

    Full Text Available Abstract Background Little is known about the effects of professional staffing on cancer surgical outcomes. The present study aimed to investigate the association between cancer surgical outcomes and physician/nurse staffing in relation to hospital volume. Methods We analyzed 131,394 patients undergoing lung lobectomy, esophagectomy, gastrectomy, colorectal surgery, hepatectomy or pancreatectomy for cancer between July and December, 2007–2008, using the Japanese Diagnosis Procedure Combination database linked to the Survey of Medical Institutions data. Physician-to-bed ratio (PBR and nurse-to-bed ratio (NBR were determined for each hospital. Hospital volume was categorized into low, medium and high for each of six cancer surgeries. Failure to rescue (FTR was defined as a proportion of inhospital deaths among those with postoperative complications. Multi-level logistic regression analysis was performed to examine the association between physician/nurse staffing and FTR, adjusting for patient characteristics and hospital volume. Results Overall inhospital mortality was 1.8%, postoperative complication rate was 15.2%, and FTR rate was 11.9%. After adjustment for hospital volume, FTR rate in the group with high PBR (≥19.7 physicians per 100 beds and high NBR (≥77.0 nurses per 100 beds was significantly lower than that in the group with low PBR ( Conclusions Well-staffed hospitals confer a benefit for cancer surgical patients regarding reduced FTR, irrespective of hospital volume. These results suggest that consolidation of surgical centers linked with migration of medical professionals may improve the quality of cancer surgical management.

    To describe the scope and outcomes of elective pediatric surgical procedures performed during combat operations. The care of patients in Operation Enduring Freedom (OEF) includes elective humanitarian surgery on Afghan children. Unlike military reports of pediatric trauma care, there is little outcome data on elective pediatric surgical care during combat operations to guide treatment decisions. All elective surgical procedures performed on patients≤16years of age from May 2012 through April 2014 were reviewed. Procedures were grouped by surgical specialty and were further classified as single-stage (SINGLE) or multi-stage (MULTI). The primary endpoint was post-operative complications requiring further surgery, and the secondary endpoint was post-operative follow up. A total of 311 elective pediatric surgical procedures were performed on 239 patients. Surgical specialties included general surgery, orthopedics, otolaryngology, ophthalmology, neurosurgery and urology. 178 (57%) were SINGLE while 133 (43%) were MULTI. Fifteen patients required 32 procedures for post-operative complications. Approximately half of all procedures were performed as outpatient surgery. Median length of stay for inpatient was 2.2days, and all patients survived to discharge. The majority of patients returned for outpatient follow-up (207, 87%), and 4 patients (1.7%) died after discharge. Elective pediatric surgical care in a forward deployed setting is feasible; however, limitations in resources for perioperative care and rehabilitation mandate prudent patient selection particularly with respect to procedures that require prolonged post-operative care. Formal guidance on the process of patient selection for elective humanitarian surgery in these settings is needed. Published by Elsevier Inc.

    Objective We sought to evaluate and compare the outcomes of different surgical protocols for papillary thyroid cancer (PTC) located in the isthmus in a retrospective intention-to-treat analysis. Patients and methods The data of 3,068 patients who received thyroidectomy due to thyroid cancer in our center were reviewed. Of these, 103 patients had a dominant carcinoma located in the isthmus. Various baseline and tumor characteristics and surgical outcomes were evaluated and compared with respect to the different surgical protocols (85 cases with total thyroidectomy and 18 cases with less-than-total thyroidectomy). Univariate and multivariate analyses were performed to identify resected patients who developed recurrence with isthmic PTC. Results The postoperative complication rates were comparable between the two groups (17.6% versus 11.1%, P=0.500). Although the total thyroidectomy group showed a much higher rate (P=0.004) and number (P0.05). Tumor recurrence was observed in five patients, including two patients in the total thyroidectomy group and three patients in the less-than-total thyroidectomy group; the tumor recurrence rate in the total thyroidectomy group was significantly lower than that in the less-than-total thyroidectomy group (P=0.040). Univariate and multivariate analyses indicated less-than-total thyroidectomy as a risk factor for tumor recurrence in PTC cases with tumors located at the isthmus (hazard ratio: 1.870, 95% confidence interval: 1.320–2.218, P<0.001). Conclusion Our findings indicate that total thyroidectomy is an appropriate initial surgical protocol for isthmic PTC due to the lower recurrence rate, comparable postoperative complication rate, and parathyroid function recovery.

    Full Text Available BACKGROUND: Laparoscopic gastrectomy (LG for gastric cancer has increased in popularity due to advances in surgical techniques. The aim of this study is to validate the efficacy and safety of laparoscopic gastrectomy for gastric cancer compared with open gastrectomy (OG. METHODS: The study comprised 3,580 patients who were treated with curative intent either by laparoscopic gastrectomy (2,041 patients or open gastrectomy (1,539 patents between January 2005 and October 2013. The surgical outcomes were compared between the two groups. RESULTS: Laparoscopic gastrectomy was associated with significantly less blood loss, transfused patient number, time to ground activities, and post-operative hospital stay, but with similar operation time, time to first flatus, and time to resumption of diet, compared with the open gastrectomy. No significant difference in the number of lymph nodes dissected was observed between these two groups. The morbidity and mortality rates of the LG group were comparable to those of the OG group (13.6% vs. 14.4%, P = 0.526, and 0.3% vs. 0.2%, P = 0.740. The 3-year disease-free and overall survival rates between the two groups were statistically significant (P<0.05. According to the UICC TNM classification of gastric cancer, the 3-year disease-free and overall survival rates were not statistically different at each stage. CONCLUSIONS: Our single-center study of a large patient series revealed that LG for gastric cancer yields comparable surgical outcomes. This result was also true of local advanced gastric cancer (AGC. A well-designed randomized controlled trial comparing surgical outcomes between LG and OG in a larger number of patients for AGC can be carried out.

    Retinal oximeter is a new machine which has been used in the diagnose, treatment and research of several ophthalmic diseases for recent years. It allows ophthalmologists to gain retinal oxygen saturation directly. Therefore, retinal oximeter might be useful for ophthalmologists to understand ophthalmic diseases more deeper and clarify the impact of ischemia on retinal function. It has been reported in the literatures that retinal oximeter has potentially useful diagnostic and therapeutic indications in various eye diseases such as diabetic retinopathy, central retinal vein and artery occlusion, retinitis pigmentosa, glaucomatous optic neuropathy, et al. In this thesis, the application of retinal oximeter in ophthalmology is reviewed.

    Full Text Available Introduction and Objective. The Nuss procedure is widely used in the treatment of pectus excavatum worldwide. Postoperative pectus bar infection is one of the most serious complications associated with this procedure. Therefore, early detection of signs of implant infection is very important. However, this is difficult, and effective methods have yet to be established. Methods. We use a handheld infrared thermal imaging camera to screen patients for postoperative infection following the Nuss procedure. Here, we report a 28-year-old man with recurrent postoperative (Ravitch procedure pectus excavatum. Results. Infrared thermography camera clearly indicated slight cellulitis in the right chest. Conclusion. Our technique may assist in preventing postoperative bar infection and removal caused by severe bar infection. Furthermore, this camera is potentially suitable for many situations in infection monitoring following subcutaneous implant surgery.

    Full Text Available Purpose. To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK. Methods. We report the case of a 17 years old patient with a history of congenital glaucoma, trabeculectomy and multiple corneal graft rejections, presenting total limbal cell deficiency. To reduce the possibility of graft rejection in the left eye after a new PK, a two step procedure was performed. At first the patient underwent a combined HLA matched limbal stem cells allograft (LAT and AMT and then, 10 months later, a new PK. Results. During 12 months of follow-up, the corneal graft remained stable and smooth, with no sign of graft rejection. Conclusions. In our patient, the prophylactic use of LAT from HLA-matched donors and AMT before PK, may result in a better prognosis of corneal graft survival.

    Purpose: To report the rate of flap-related complications in LASIK surgery performed by in-training ophthalmology residents and to analyze the risk factors for these complications. Methods: We analyzed 273 flap dissections in 145 patients from March 2013 to February 2014. We included all LASIK surgeries performed by 32 ophthalmology residents using a Moria M2 microkeratome. All the flap-related complications were noted. Comparison between both groups with and without complications was performed with an independent Student's t-test and relative risks were calculated. Results: There were 19 flap-related complications out of the 273 flap dissections (6.95%). The most common complication was incomplete flap dissection (n = 10; 3.66%), followed by free-cap (n = 5; 1.83%), and flap-buttonhole (n = 2; 0.73%). There was no significant difference between the complicated and uncomplicated cases in terms of the right versus the left eye, pachymetry results, white-to-white diameter, and spherical equivalent. But this difference was significant for mean keratometry (P = 0.008), K-min (P = 0.01), and K-max (P = 0.03) between these groups. Final visual acuity after rescheduling laser treatment was similar in both groups. Relative risks for flap-related complications were 2.03 for the first LASIK surgery (CI 95% 0.64 to 6.48; P = 0.22) and 1.26 (CI 95% 0.43 to 3.69; P = 0.66) for the surgeon's flap-related complications. Female gender presented an odds ratio of 2.48 (CI 95% 0.68 to 9.00; P = 0.16) for complications. Conclusion: Flap-related complications are common intraoperative event during LASIK surgery performed by in-training ophthalmologists. Keratometries and surgeon's first procedure represent a higher probability for flap related complications than some other biometric parameters of patient's eye. PMID:27621782

    1995-10-01

    The surgical correction of the retention of upper canines is made easier by the direct bonding method, furthermore it increases the chances of successful treatment. At the same time at teen-age the treatment is usually missing, since the persistent milk-teeth in the place of impacted canines are ensuring the aesthetic effect. The late treatment is motivated by aesthetic aspects also by loosing the milk-canines. Thus the indication of the treatment is a cure only from the orthodontist's aspect, from the patient's view it's only the aesthetics.

    2015-11-01

    Full Text Available Objective: To report the clinical presentation of malarial retinopathy in an adult, emphasizing the importance of this diagnosis for the clinical suspicion and prognosis of cerebral malaria. Methods: A 39-year-old caucasian man presented with hemolytic anemia, thrombocytopenia, acidemia and acute renal failure, developing severe encephalopathy. The diagnosis of malaria was done and after systemic stabilization, the patient noticed a central scotoma in the left eye. Ophthalmological examination revealed retinal features of malarial retinopathy. Results: At one-month follow-up, the patient had improved his systemic condition and the left eye scotoma had disappeared. Visual acuity was 20/20 in both eyes and on examination almost all lesions had regressed. Conclusion: Malarial retinopathy is a diagnostic factor and a prognosis indicator of severe infection, usually with brain involvement. The knowledge of the ophthalmological features associated with severe malaria, which is more frequent in children but can also occur in adults, becomes imperative in order to reduce the risk of neurologic sequelae and associated mortality.

    The aim of the study was to investigate the prevalence and the incidence of ocular complications in contact sport disciplines in a large population of professional and amateur athletes over a period of 3 years. We performed a retrospective review of 694 medical records from athletes examinated from 2008 to 2011. The following data were collected during the routine visit for agonistic sports eligibility: medical history, age, weight, years of sport practice, approximate number of matches, head and eyes injuries during and beyond of the match and a through ocular history. All athletes underwent a detailed ophthalmological evaluation. The follow-up of each athlete was carried out during the following routine visit for agonistic sports eligibility. Most common disorders observed were: peripheral retinal degeneration, blepharitis, conjunctival and corneal diseases with a prevalence of 7%, 4%, 7% and 4% respectively. It was observed a positive correlation between peripheral retinal degeneration and age in amateur male boxers. Moreover, we noticed an incidence of 6% of laser therapeutic treatments as a result of retinal holes or degenerations, during the follow-up. Contact sport disciplines did not result in higher prevalence of severe ocular lesion. Both conjuntival diseases and peripheral retinal degenerations represented the ophthalmologic disorders with the higher prevalence in our sample. In particular, peripheral retinal degeneration is remarkable because of the increased risk of retinal detachment. Dyschromatopsie, even if quite rare, should be considered when analysing the reception of shots, since gloves in most cases are either red or blue.

    This work is focused on the detailed computer simulation of the key stages involved in a shape memory alloy (SMA) osteosynthesis bone stapling procedure. To this end, a recently developed three-dimensional constitutive SMA material model was characterized from test data of three simple uniaxial-isothermal-tension experiments for powder metallurgically processed nickel-rich NiTi (PM/NiTi-P) material. The calibrated model was subsequently used under the complex, thermomechanical loading conditions involved in the surgical procedure using the body-temperature-activated PM/NiTi-P bone staple. Our aim here is to assess the immediate and post-surgical performance characteristics of the stapling operation using the material model. From this study: (1) it was found that adequate compressive forces were developed by the PM/NiTi-P bone staple, with the tendency of this force to even increase under sustained thermal loading due to the intrinsic "inverse relaxation phenomena" in the SMA material, (2) the simulation results correlated well with those from experimental measurements, (3) the body-temperature-activated PM/NiTi-P staple was proved to be clinically viable, providing a stable clamping force needed for speedy coaptation of the fractured bones, and (4) these realistic assessments crucially depend on the use of suitable and comprehensive SMA material models.

    Full Text Available AIM To compare the changes in blood glucose level associated with administration of adrenaline containing local anesthetic in diabetic and non-diabetic patients undergoing minor oral surgical procedures. METHODS AND MATERIAL The study included 150 well controlled diabetic patients and 150 non-diabetic healthy patients in age group of 40-60 years who underwent minor oral surgical procedures (trans alveolar extractions, alveoplasty and flap surgeries. Patients in both the group were administered 1.8ml of local anesthetic agent containing 1:100,000 adrenaline for inferior alveolar nerve block and 0.2 ml of anesthetic agent for long buccal nerve block. Blood glucose levels were assessed and compared during pre-operative and one hour post-operative period. STATISTICAL ANALYSIS The comparison of the random blood sugar levels preop and postop in both the groups were compared using paired t test and RBS levels between two groups were analysed using unpaired t test. P value less than 0.05 was considered statistically significant. RESULTS No statistically significant change in post-operative blood glucose level was noted between the diabetic and non-diabetic patients. CONCLUSION The study concluded that it is safe to administer local anesthetic containing 1:100,000 adrenaline in smaller volumes to well controlled diabetic patients.

Both the literature using PubMed and Google Scholar were searched using the following terms: application$, smartphone$, app$, app*, surgery, surgical, surg*, general surgery, general surg*, bariatric$, urology and plastic surgery, ortho*, orthop(a)edic, cardiac surgery, cardiothoracic, neurosurgery, and ophthalmology. The search yielded 38 articles of which 23 were eligible. Each of the key specialties was searched in the Apple iTunes App Store for iPhone iOS and the Google Play Android application store. In total, there were 621 surgical applications for Apple iPhone iOS and 97 identified on Android's Google Play. There has been a 9-fold increase in the number of surgical applications available for the Apple iPhone iOS from 2009 to 2012. Of these applications there were 126 dedicated to plastic surgery, 79 to orthopedics, 41 to neurosurgical, 180 to general surgery, 36 to cardiac surgery, 121 to ophthalmology, and 44 to urology. There was a wide range of applications ranging from simple flashcards to be used for revision to virtual surgery applications that provided surgical exposure and familiarization with common operative procedures. Despite the plethora of surgical applications available for smartphones, there is no taxonomy for medical applications. Only 12% were affiliated with an academic institution or association, which highlights the need for greater regulation of surgical applications. © The Author(s) 2014.

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

    The Sauvé-Kapandji procedure has become popular for the treatment of disorders of the distal radioulnar joint in patients with rheumatoid arthritis, but this procedure is impossible to perform in patients with poor bone quality in the distal part of the ulna. We have modified the procedure for patients with poor bone quality in the distal part of the ulna. The modified procedure involves resecting the distal part of the ulna, making a drill-hole in the ulnar cortex of the distal part of the radius, rotating the resected portion of the ulna 90 degrees, inserting it into the distal part of the radius, and fixing it at that site with use of an AO cancellous-bone screw. In the present report, we describe the new operative technique and report the results after a minimum duration of follow-up of three years. This operation was performed in fifty-six patients (sixty-six wrists) with rheumatoid arthritis. The mean age at the time of the operation was 59.3 years. The mean duration of follow-up was forty-eight months. Patients were evaluated in terms of wrist pain, grip strength, and range of motion. Radiographic evaluation included calculation of the carpal translation index to assess the extent of ulnar translation of the carpus. Osseous union was achieved in all cases. Wrist pain resolved or decreased in all patients. The mean total range of forearm rotation increased from 144 degrees preoperatively to 167 degrees at the time of the most recent follow-up (p Kapandji procedure results in rigid fixation of the grafted bone. The technique provides sufficient osseous support of the carpus even in patients with rheumatoid arthritis and poor bone quality in the distal part of the ulna.

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p 10 days (OR 1.411, p = 0.010), oxygen supplementation (OR 1.645, p = 0.010), nutritional support (OR 1.403, p = 0.009), seizure disorder (OR 1.250, p = 0.021), and longer operative time (per hour increase, OR 1.059, p = 0.029). CONCLUSIONS This study may aid in identifying patients at risk for unplanned readmission following pediatric neurosurgery

    The International Council of Ophthalmology (ICO) is a global organization with a regional focus. Working in partnership with supranational and ICO member societies, the ICO is building a "World Alliance for Sight" to improve access to the highest-quality eye care worldwide. Designed to preserve and restore vision on an international scale, the ICO initiative, "Refocusing Ophthalmic Education," enhances ophthalmic education of residents, subspecialists, medical students, and allied eye care personnel by redefining the most effective ways to teach and in creating beneficial educational opportunities. The "Teaching the Teachers" program helps ophthalmic educators incorporate more effective methods of training and continuing professional development to meet societal needs, achieved in part through regional courses for residency program directors; symposia, and keynote talks presented by ICO's World Ophthalmology Educational Colloquium, Conferences for Ophthalmic Educators, and ophthalmic surgical competency rubrics. Recognizing that standardized curricula are essential for consistent ophthalmic education, the ICO has developed a curricular framework whereby goals, expectations, knowledge base, competencies, and technical training are delineated. The ICO is defining worldwide models of team training and compiling best practice, which will include training-program accreditation to ensure improvement in the education of ophthalmologists. International Council of Ophthalmology Web-based teaching courses, a Webinar Network, and a technology blog further support information and communication technologies for teaching and learning. At the ICO's Center for Ophthalmic Educators (educators.icoph.org), trainers will find valuable teaching resources in multiple languages as well as ways to share ideas and collaborate with peers and other ophthalmic educators.

    Full Text Available Introduction: Anxiety is a common disorder in patients before surgery. Inappropriately managed anxiety can cause psychological and physiological reactions and will affect the process of surgery and recovery. Therefore, this study examined the effects of hand mas-sage on anxiety in patients undergoing ophthalmology surgery using local anesthesia. Methods: In this interventional study, 52 patients who were supposed to undergo oph-thalmology surgery using local anesthesia were studied. Patients were randomly as-signed to two groups of intervention, who received hand massage before surgery (n = 27 and control (n = 25. Massaging lasted for 5 minutes (2.5 minutes on each hand before surgery. Stroking and scrubbing methods were performed by 2 trained research-ers. Anxiety level, blood pressure, heart rate, and respiratory rate were measured before and after the intervention in both groups. Anxiety was evaluated using Spielberger State-Trait Anxiety Inventory. Data was analyzed by chi-square, independent samples t-test, and paired t-test. Results: There were no significant differences in mean anxiety, systolic blood pressure, diastolic blood pressure, heart rate, and respiratory rate between the two groups before the intervention (p > 0.05. However, there was a significant differenc in the mean stress level between the two groups after the intervention (p 0.05. Conclusion: Our findings suggested that 5 minutes of hand massage before ophthalmology surgery (under local anesthesia could reduce anxiety. Therefore, this method can be used to increase patient comfort and reduce anxiety before surgical interventions.

    Various vestibular extension procedures have been described in the literature over the past 6 decades, including the use of free gingival grafts. An acellular dermal allograft has been used as a substitute for autogenous soft tissue grafts in root coverage procedures. This clinical report describes the use of such an allograft as a substitute for palatal donor tissue in the vestibular extension of an edentulous maxillary arch with multiple frenum attachments before fabrication of a complete denture. In this patient, healing was uneventful, and 6-month clinical observations demonstrated an apical positioning of the mucogingival junction with an increase in vestibular depth, and the absence of multiple frenae. The acellular dermal allograft appears to be a useful substitute for autogenous palatal grafts in preprosthetic surgery. This approach has many advantages over the free gingival graft, including no donor site morbidity, unlimited availability, and better color match.

    Hilkert, Sarah M; Cebulla, Colleen M; Jain, Shelly Gupta; Pfeil, Sheryl A; Benes, Susan C; Robbins, Shira L

    As the ophthalmology accreditation system undergoes major changes, training programs must evaluate residents in the 6 core competencies, including appropriately communicating bad news. Although the literature is replete with recommendations for breaking bad news across various non-ophthalmology specialties, no formal training programs exist for ophthalmology. There are many valuable lessons to be learned from our colleagues regarding this important skill. We examine the historic basis for breaking bad news, explore current recommendations among other specialties, and then evaluate a pilot study in breaking bad news for ophthalmology residents. The results of this study are limited by a small number of residents at a single academic center. Future studies from multiple training programs should be conducted to further evaluate the need and efficacy of formal communication skills training in this area, as well as the generalizability of our pilot training program. If validated, this work could serve as a template for future ophthalmology resident training and evaluation in this core competency.

    For the eyeball composed of membrane and liquid, the contrast of ultrasound imaging is not high due to its small variance in acoustic impedance. As a new imaging modality, photoacoustic tomography combines the advantages of pure optical and ultrasonic imaging together and can provide high resolution, high contrast images. In this paper, the feasibility of photoacoustic tomography for ophthalmology is studied experimentally. A Q-switched Nd:YAG pulsed laser with 7-ns pulse width is used to generate photoacoustic signal of a porcine eyeball in vitro. The two-dimensional (2D) optical absorption image of the entire eyeball is reconstructed by time-domain spherical back projection algorithm. The imaging results agree well with the histological structure of the eyeball and show a high imaging contrast.

  15. "Eyes" on the thrones: imperial ophthalmologic nicknames.

    Lascaratos, J

    1999-01-01

    Several Greek and Byzantine sovereigns are known in history by nicknames that are of ophthalmologic origin; the sobriquets derive from characteristics of their eyes or their actions in relation to the eyes. The first was Antigonos I Monophthalmus (the One-eyed), who was the most eminent successor of Alexander the Great and Sovereign of Eastern Mediterranean Asia. He obtained his nickname at an early age when he lost one eye fighting at the seige of Perinthos, as a general of King Philip of Macedon (father of Alexander the Great). Several Byzantine emperors also have a number of similar nicknames, such as Anastasius I Dicoros (with Heterochromia Iridis), Alexius V Ducas Murtzuphlus (with Scowling Eyebrows), and Andronicus I Comnenus Misophaes (Hater of Sunlight, since he blinded a great number of his opponents). To these must be added the Byzantine Empress Zoe Carvounopsina (with Coal-black Eyes).

    Sinusitis is a frequent and very often under-diagnosed condition. Despite the constantly increasing number of antibiotics with improved efficacy, prevention of its complications remains difficult. The prevalence of these complications is estimated at 3.7%. Their clinical presentation is highly variable making the diagnosis difficult and thereby increasing mortality. In this article, historical, epidemiological, pathophysiological, clinical and therapeutic aspects of neuro-ophthalmological complications of sinusitis are reviewed. For didactic reasons, the various complications have been divided into extra-axial, intra-axial, vascular, and orbital. Specific paragraph have been devoted to sinusitis-related bone complications and pain syndromes. It's however obvious that various more or less complex associations of these complications can be seen in daily practice.

    Paraneoplastic syndromes that affect the visual pathways and present with neuro-ophthalmologic signs or symptoms may involve the afferent or efferent systems. Afferent syndromes may involve the optic nerve or retina and, in some cases, these may be associated with systemic neurologic disease. Efferent symptoms typically affect eye movements and may involve the neuromuscular junction or involuntary eye movements. Literature review and personal clinical and research experience. Diagnosis of paraneoplastic syndromes relies on clinical and laboratory evaluations. In the appropriate clinical setting, the presence of specific antibodies may help confirm the diagnosis. In some cases, the visual pathway disturbance precedes a diagnosis of malignancy. Astute observation and selective evaluation and management are critical to establish the correct diagnosis and institute therapeutic approaches that can be sight or life saving.

    2012-01-01

    Full Text Available Background: In today′s world, people are very much aware about their looks and personality. They are getting more concerned about the esthetics and thus are not ready to compromise the appearance of black holes, especially in the anterior region of the mouth. Various techniques like orthodontic correction, prosthetic veneers and various periodontal surgical methods have been used to cover these unaesthetic open embrasures. In the present study, a variant technique given by Beagle in 1992 was used to cover these open gingival embrasures. The technique uses a gingival flap from the labial aspect to close the open gingival embrasures thus solving the problem of black holes. Aims and Objectives: This clinical study was aimed to reconstruct the lost or blunted interdental papillae with gingival tissue for esthetic purpose and for maintaining oral health with the objective to determine the extent to which the procedure can revert the maxillary esthetics. Materials and Methods: The patients selected were those who were having a complaint of at least one black hole in the maxillary anterior region with grade ′0′ or ′1′ type of contour of interdental tissues. A total of 39 open embrasures were surgically closed using this technique. Various indices were taken pre-surgically and then again post surgically. Results: Plaque index and gingival index showed an initial increase in the scores at the end of 1 week. Later, there was a gradual fall till the end of the study. Bleeding index significantly increased at the end of 12 weeks ( P<0.001 but reduced to insignificant levels at the end of 24 weeks ( P<0.09. The sulcus depth increased by about 1.19 mm. There was improvement in the contour of interdental tissues in 51% of cases and in 38.46% the interdental papillae completely obliterated the open embrasures. Conclusion: The surgical technique used here for reconstruction of interdental papilla was fairly successful. However, use of bone grafts or

    Reoperative procedure for the treatment of a failed mitral bioprosthesis is associated with considerable risk. In some cases, mortality is high and might contraindicate the benefit of the procedure. The minimally invasive valve-in-valve (ViV) transcatheter mitral valve implant offers an alternative less-invasive approach, reducing morbidity and mortality. The objective of this paper was to evaluate the mitral ViV approach using the Braile Inovare prosthesis. The transcatheter balloon-expandable Braile Inovare prosthesis was used in 12 cases. Procedures were performed in a hybrid operating room, under fluoroscopic and echocardiographic control. Through left minithoracotomy, the prostheses were implanted through the cardiac apex. Serial echocardiographic and clinical examinations were performed. Follow-up varied from 1 to 30 months. A total of 12 transapical mitral ViV procedures were performed. Patients had a mean age of 61.6 ± 9.9 years and 92% were women. Mean logistic EuroSCORE was 20.1%. Successful valve implantation was possible in all cases. In one case, a right lateral thoracotomy was performed for the removal of an embolized prosthesis. There was no operative mortality. Thirty-day mortality was 8.3%. Ejection fraction was preserved after the implant (66.7%; 64.8%; P  = 0.3). The mitral gradient showed a significant reduction (11 mmHg; 6 mmHg; P  implant in a failed bioprosthesis is an effective procedure. This possibility might alter prosthesis selection in the future initial surgical prosthesis selection, favouring bioprostheses. Further large trials should explore its safety.

    Perianal abscess is the most common disease in anal, almost in man. It is caused by infections of anal glands, and the inflammations spread to the perianal gap, eventually abscess formation in perianal. There are a number of perianal abscess diseases caused by systemic diseases, such as inflammatory bowel disease, cancer and hematological system diseases. Whatever the perianal abscess arises from the infection of anal glands or the systemic diseases, in common, the strategy of therapy is incision and drainage. But after incision and drainage, the formation of fistula rate is higher. Abscess often spread widely in perianal, so improper surgical treatment may cause potentially residual cavity, leading to recurrent abscess and fistula formation. according to the characteristics of the anatomy around the anus, The author takes″three cavity clearance″ to drainage the perianal abscess completely, and achieves certain results.

    The present study was conducted to determine the occurrence of potentially pathogenic free-living amoeba in ophthalmology wards in reference hospitals in Iran. Since an increasing number of Acanthamoeba Keratitis cases after eye surgery and eye trauma have been recently observed in this country, it could be possible that the disinfection procedures undertaken in the clinical setting may not have a good hygiene and disinfection procedures, hence the aim of this study. Therefore, 42 dust and biofilm samples were collected from different areas of ophthalmology wards and checked for the presence of FLA using morphological criteria, PCR based analysis and DNA sequencing. Of the 42 samples from dust and biofilm sources, 18(42.86%) isolates were found to contain FLA and 12(92.3%) isolates belonged to Acanthamoeba T4 genotype. Isolation of the pathogenic genotype T4 from medical instruments, including slit lamp in corneal wards, may be a threat for patients undergoing eye surgery in these wards. Other FLA isolated in this study included Acanthamoeba genotype T5, Vahlkampfia sp, Naegleria australiensis, Vermamoeba vermiformis and Echinamoeba exudans. To our knowledge, this is the first report of the presence of potentially pathogenic FLA in ophthalmology wards in Iran. Improved disinfection methods and monitoring of hospitals ward are thus necessary in this area in order to minimize the risk of infection in patients.

    OBJECTIVE Surgical site infection (SSI) following CSF shunt operations has been well studied, yet risk factors for nonshunt pediatric neurosurgery are less well understood. The purpose of this study was to determine SSI rates and risk factors following nonshunt pediatric neurosurgery using a nationwide patient cohort and an institutional data set specifically for better understanding SSI. METHODS The authors reviewed the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-P) database for the years 2012-2014, including all neurosurgical procedures performed on pediatric patients except CSF shunts and hematoma evacuations. SSI included deep (intracranial abscesses, meningitis, osteomyelitis, and ventriculitis) and superficial wound infections. The authors performed univariate analyses of SSI association with procedure, demographic, comorbidity, operative, and hospital variables, with subsequent multivariate logistic regression analysis to determine independent risk factors for SSI within 30 days of the index procedure. A similar analysis was performed using a detailed institutional infection database from Children's of Alabama (COA). RESULTS A total of 9296 nonshunt procedures were identified in NSQIP-P with an overall 30-day SSI rate of 2.7%. The 30-day SSI rate in the COA institutional database was similar (3.3% of 1103 procedures, p = 0.325). Postoperative time to SSI in NSQIP-P and COA was 14.6 ± 6.8 days and 14.8 ± 7.3 days, respectively (mean ± SD). Myelomeningocele (4.3% in NSQIP-P, 6.3% in COA), spine (3.5%, 4.9%), and epilepsy (3.4%, 3.1%) procedure categories had the highest SSI rates by procedure category in both NSQIP-P and COA. Independent SSI risk factors in NSQIP-P included postoperative pneumonia (OR 4.761, 95% CI 1.269-17.857, p = 0.021), immune disease/immunosuppressant use (OR 3.671, 95% CI 1.371-9.827, p = 0.010), cerebral palsy (OR 2.835, 95% CI 1.463-5.494, p = 0.002), emergency operation (OR 1

    There are currently no assessments of the impact of surgical complications on health-related quality of life in gynecology and gynecologic oncology. This is despite complications being a central focus of surgical outcome measurement, and an increasing awareness of the need for patient-reported data when measuring surgical quality. We sought to measure the impact of surgical complications on health-related quality of life at 1 month postoperatively, in women undergoing gynecologic and gynecologic oncology procedures. This is a prospective cohort study of women undergoing surgery by gynecologic oncologists at a tertiary care academic center from October 2013 through October 2014. Patients were enrolled preoperatively and interviewed at baseline and 1, 3, and 6 months postoperatively. Health-related quality of life measures included validated general and disease-specific instruments, measuring multiple aspects of health-related quality of life, including anxiety and depression. The medical record was abstracted for clinical data and surgical complications were graded using validated Clavien-Dindo criteria, and women grouped into those with and without postoperative complications. Bivariate statistics, analysis of covariance, responder analysis, and multivariate modeling was used to analyze the relationship of postoperative complications to change health-related quality of life from baseline to 1 month. Plots of mean scores and change over time were constructed. Of 281 women enrolled, response rates were 80% (n = 231/281) at baseline, and from that cohort, 81% (n = 187/231), 74% (n = 170/231), and 75% (n = 174/231) at 1, 3, and 6 months, respectively. The primary analytic cohort comprised 185 women with completed baseline and 1-month interviews, and abstracted clinical data. Uterine (n = 84, 45%), ovarian (n = 23, 12%), cervical (n = 17, 9%), vulvar (n = 3, 2%), and other (n = 4, 2%) cancers were represented, along with 53 (30%) cases of benign disease. There

    We present the delivery of high energy microsecond pulses through a hollow-core negative-curvature fiber at 2.94 µm. The energy densities delivered far exceed those required for biological tissue manipulation and are of the order of 2300 J/cm(2). Tissue ablation was demonstrated on hard and soft tissue in dry and aqueous conditions with no detrimental effects to the fiber or catastrophic damage to the end facets. The energy is guided in a well confined single mode allowing for a small and controllable focused spot delivered flexibly to the point of operation. Hence, a mechanically and chemically robust alternative to the existing Er:YAG delivery systems is proposed which paves the way for new routes for minimally invasive surgical laser procedures.

    Full Text Available The conventional medical management of emphysema using bronchodilators and anti-inflammatory agents has a limited benefit in patients having advanced hyperinflation of lungs due to destruction of elastic tissue. The natural course of Chronic Obstructive Pulmonary Disease (COPD has been shown to be altered by only smoking cessation and oxygen therapy so far. The lung volume reduction surgery is viewed as another modality to change the natural history of emphysema in recent years. For patients with more generalized emphysema, resection of lung parenchyma improves elastic recoil and chest wall mechanics. An extensive literature search has demonstrated that carefully selected patients of emphysema (i.e. upper lobe predominant disease, low exercise capacity and Forced Expiratory Volume in First Second (FEV1 and DLco and #8804; 20% of predicted receive benefits in terms of symptomatic improvement and physiologic response following Lung Volume Reduction Surgery (LVRS. The resurgent interest in LVRS and National Emphysema Treatment Trial findings for emphysema have stimulated a range of innovative methods, to improve the outcome and reduce complications associated with current LVRS techniques. These novel approaches include surgical resection with compression/banding devices, endobronchial blockers, sealants, obstructing devices and valves and endobronchial bronchial bypass approaches. Experimental data and preliminary results are becoming available for some of these approaches. Most of the published studies so far have been uncontrolled and unblinded. Overall, extensive research in the near future will help to determine the potential clinical applicability of these new approaches to the treatment of emphysema symptoms.

    The objective of the study is to introduce the surgical procedure of the lumbosubarachnoid-lumboepidural (L-L) shunting performed as treatment for idiopathic normal-pressure hydrocephalus (iNPH) and its follow-up. The subjects were five patients with probable iNPH (aged 78-85 years; mean age 81 years; four males and one female) who were judged to be at high risk from general or lumbar anesthesia due to their systemic complications and age. The L-L shunt operation was performed for all the patients under local anesthesia using Codman-Hakim Programmable Valve(®) (Codman & Shurtleff, Inc., Raynham, Massachusetts, USA). The initial pressure for all patients was set at 8 cmH2O. The evaluation of shunt efficacy and the lumbar epidural space cerebrospinal fluid (CSF) absorption test (injection of contrast media into epidural space) were performed both on the operation day and during follow-up period (9-12 months). The shunt operation was judged to be effective in four out of five patients (regarded as shunt responders), whereas no improvement in symptoms was seen in one patient (regarded as shunt nonresponder) where the shunting had no effect after the initial pressure was changed to 4 cmH2O. The lumbar epidural space CSF absorption test both on the operation day and during the follow-up period confirmed absorption in all patients. The L-L shunting is useful for patients with probable iNPH who are at high risk from general or lumbar anesthesia due to their systemic complications and age. CSF was continuously absorbed in the lumbar epidural space during postoperative follow-up period. A longer follow-up is required to establish this surgical procedure.

    Full Text Available Background: We compared i-gel and ProSeal laryngeal mask airway (PLMA regarding time taken for insertion, effective seal, fiberoptic view of larynx, ease of Ryle′s tube insertion, and postoperative sore throat assessment. Materials and Methods: In a prospective, randomized manner, 48 adult patients of American Society of Anesthesiologists I-II of either gender between 18 and 60 years presenting for a short surgical procedure were assigned to undergo surgery under general anesthesia on spontaneous ventilation using either the i-gel or PLMA. An experienced nonblinded anesthesiologist inserted appropriate sized i-gel or PLMA in patients using standard insertion technique and assessed the intraoperative findings of the study regarding regarding time taken for respective device insertion, effective seal, fiberoptic view of larynx, ease of Ryle′s tube insertion, and postoperative sore throat assessment. Postoperative assessment of sore throat was done by blinded anesthesia resident. Results: The time required for insertion of i-gel was lesser (21.98 ± 5.42 and 30.60 ± 8.51 s in Group I and Group P, respectively; P = 0.001. Numbers of attempts for successful insertions were comparable and in majority, device was inserted in first attempt. The mean airway leak pressures were comparable. However, there were more number of patients in Group P who had airway leak pressure >20 cm H 2 O. The fiberoptic view of glottis, ease of Ryle′s tube insertion, and incidence of complications were comparable. Conclusion: Time required for successful insertion of i-gel was less in adult patients undergoing short surgical procedure under general anesthesia on spontaneous ventilation. Patients with airway leak pressure >20 cm H 2 O were more in PLMA group which indicates its better suitability for controlled ventilation.

    Pediatric patients with cleft lip and palate undergo numerous surgeries throughout their childhood and early adulthood to correct the aesthetic and functional stigmata of their diagnoses. This study identifies patient and clinical factors that contribute to the number of surgeries and anesthesia events children undergo for their cleft repair. Retrospective chart review was performed using the genetic and dysmorphology database at Rady Children's Hospital San Diego. All patients with cleft lip or cleft palate diagnosis who underwent surgery at Rady Children's Hospital San Diego between 1988 and 2014 were included. A sample size of 71 patients was analyzed. Poisson regression was used to determine if there is a relationship between each variable of interest and the number of procedures. For our sample of 71 patients, the average number of surgical procedures was 8.6 (SD, 4.4). The average number of anesthesia events was 6.7 (SD, 3.3). Across and within diagnosis, race and sex were not statistically significant factors in patients' number of surgeries. Patients with bilateral cleft lip and palate (BCLP) and unilateral cleft lip and palate had, on average, 10 and 9.4 procedures, respectively. This is in contrast to patients with unilateral cleft lip and isolated cleft palate who had, on average, 5.3 and 5.9 procedures, respectively. This difference was significant (P value = 0.01). Patients were also compared based on continuity of care. Patients who had their cleft surgeries by multiple plastic surgeons affiliated with our children's hospital had significantly more surgeries (P = 0.01). A surgical outlier subset of 17 patients (24%) was identified who had more than 10 surgeries. These patients also had, on average, 11.3 (unilateral cleft lip and palate) and 11.8 (bilateral cleft lip and palate) anesthesia events; this is in contrast to the nonoutliers who had, on average, 4.1 to 8 anesthesia events. This retrospective review identifies patient and clinical factors

    2002-06-01

    We evaluated the effect of LLLT in 68 patients who presented hypoesthesia due to odontological surgery procedures: dental implant surgeries (N=51); extraction of impacted lower third molars (N=10); endodontics in lower first molars (N=7). Lesions treated within 30 days after the nerve injury had occurred were part of the immediate group, and lesions with more than 30 days from the occurrence of the injury were part of the late group. Treatments were carried out with an infrared diode laser of 40 mW-830nm, continuous wave emission, spot size 3 mm2, and a total dosage of 18 joules per session in a contact mode of application, 20 sessions altogether. The efficacy of laser therapy in peripheral nerve regeneration is also related to the degree of the peripheral nerve lesion, and not only to the lesion duration. LLLT resulted in neurosensory functional improvement in both immediate and late treatments of hypoesthesia.

    2016-01-01

    A systematic review of the literature on the use of regional anesthesia (RA) and patient-controlled analgesia (PCA) was conducted in patients who require orthopedic extremity procedures to determine whether either analgesic technique contributes to a delayed diagnosis of compartment syndrome (CS). A total of 34 relevant articles (28 case reports and six research articles) were identified. Of all case report articles published after 2009, the majority (75%) concluded that RA does not put the patient at an increased risk of a delayed diagnosis of CS. Of these, only two relevant prospective research studies focusing on RA or PCA and their relationship to CS were identified. Neither study resulted in any cases of CS. However, both had relatively small sample sizes. Given the lack of evidence identified in this systematic review, prospective studies or large-scale retrospective data reviews are needed to more strongly advocate the use of one modality of analgesia over the other in this patient population.

    The benefit of administering beta-adrenergic blocking agents perioperatively to surgical patients at high risk for myocardial ischemia has been demonstrated in several well-designed randomized controlled trials. These benefits have included a reduction in the incidence of myocardial complications and an improvement in overall survival for patients with evidence of or at risk for coronary artery disease (CAD). We designed a retrospective study at the Ottawa Civic Hospital to investigate the use of beta-blockers in the perioperative period for high-risk general surgery patients who underwent laparotomy and to explore the reasons for failure to prescribe or administer beta-blockers when indicated. All 236 general surgery patients over the age of 50 years who underwent laparotomy for major gastrointestinal surgery between Jan. 1, 2001, and Dec. 31, 2001, were assigned a cardiac risk classification using the risk stratification described by Mangano and colleagues. The perioperative prescription and administration of beta-blockers were noted as were the patient's heart rate and blood pressure parameters for the first postoperative week, in-hospital adverse cardiac events and death. Of the 143 patients classified as being at risk for CAD or having definite evidence of CAD, 87 (60.8%) did not receive beta-blockers perioperatively. Of those who did, 43 were previously on beta-blockers and 13 had them ordered preoperatively. Patients with definite CAD were significantly more likely than others to receive beta-blockers perioperatively (p nurses irrespective of nil par os status. The mean heart rate and blood pressure parameters for patients receiving beta-blockers postoperatively was 82 beats/min and 110 mm Hg, respectively, and these values were not significantly different from the mean heart rate of patients not receiving beta-blockers. The number of postoperative cardiac events was significantly higher in patients with definite evidence of CAD, and among this group, the

    Full Text Available Interferons alpha and beta have been used worldwide for a few decades, altering the natural history of several severe diseases including hepatitis C, cancer and immune-mediated conditions such as multiple sclerosis. The adverse events profile of interferons is well established, but only isolated reports of ophthalmological complications of interferon therapy have been published. The objective of this study was to carry out a literature systematic review on the subject, bringing to light the need for careful ophthalmological monitoring of patients undergoing interferon treatment. Nearly 500 cases of ophthalmological complications related to interferon have been reported. The most frequent findings were soft exudates, hemorrhages and retina ischemia.

    Understanding the benefits of Medicaid is crucial as states decide whether to expand Medicaid under the Patient Protection and Affordable Care Act. We used the 2001 Medicaid expansion in New York to evaluate changes in use by Medicaid beneficiaries and the uninsured of breast cancer reconstruction, panniculectomy, and lower-extremity trauma management. Data for all patients 19 to 64 years old having undergone the selected procedures between 1998 and 2006 were obtained from the State Inpatient Database. We used an interrupted time series using variance weighted least squares regression to evaluate the effect of Medicaid expansion on the probability that Medicaid beneficiaries or uninsured patients received the procedures. We also determined the predicted use had there been no expansion. New York Census data were used for population-adjusted case-volume calculations. Likelihood of Medicaid as the primary payer increased significantly after expansion, 0.34% per quarter (95% CI, 0.28-0.40), without a decrease in uninsured patients receiving these procedures. This resulted in a 7.2% increase in the proportion of Medicaid beneficiaries receiving these procedures, an additional 1.9 Medicaid cases per quarter per 100,000 New York residents. In subgroup analysis, the proportion of Medicaid beneficiaries increased for breast reconstruction (0.28% per quarter; 95% CI, 0.21-0.35) and panniculectomy (0.19% per quarter; 95% CI, 0.1-0.28) without a decrease for the uninsured. Lower-extremity trauma procedures had a decreasing trend in use by uninsured patients with a slight increase for Medicaid beneficiaries (not significant). Subspecialty surgeons responded to expansion by increasing volume of procedures for Medicaid beneficiaries. This occurred without decline in care for the uninsured, suggesting that Medicaid expansion resulted in increased access for underserved patients. Although more patients received needed care once they had coverage, subgroup analysis identified

    Maintenance of a healthy periodontium is fundamental for the long term success of prosthetic restorations. Thus, prosthetic procedures with subgingival margins may affect the periodontal health if the distances between the junctional epithelium and supracrestal connective tissue attachment aren't respected, or if there is insufficient space to maintain the health of the interproximal tissues, leading to gingival inflammation, connective tissue attachment loss and bone resorption. The restorative alveolar interface (RAI) technique was described as the portion of the root surface extending from the alveolar crest apically to the restorative margin coronally. RAI consists of modifying the restorative margin position into a healthier environment, respecting the biological width and therefore allowing effective plaque control. This paper describes four clinical cases with indication for the RAI technique for maintenance of periodontal health. The cases were associated with prostheses. All cases were evaluated at 90 days and exhibited a healthy periodontal tissue. Successful outcomes were observed in the different indications for the RAI technique.

    Reported analgesic use following experimental surgery is low in rodents and there has been little published information on the frequency of analgesic use in other laboratory species. A structured literature review was conducted to examine analgesic administration in larger laboratory animals. The Scirus search engine was used to identify studies published in peer-reviewed journals that reported carrying out experimental surgery on 'large' laboratory animals, specifically rabbits, pigs, sheep, dogs and non-human primates. Seventy-four studies between 2000 and 2001 and 75 studies between 2005 and 2006 were included in the review. There was an increase in the reported administration of systemic analgesics to these species from 50% in 2000-2001 to 63% in 2005-2006. When all agents with analgesic properties were considered (systemic analgesics, local anaesthetics and anaesthetics with analgesic components), the proportion of papers that reported some form of analgesic administration to 'large' laboratory animals increased from 86% in 2000-2001 to 89% in 2005-2006. Overall rabbits, pigs, sheep, dogs and non-human primates were more likely to receive analgesics following potentially painful experimental procedures than has been reported in laboratory rodents but analgesic administration to 'large' laboratory species is still not optimal.

Demographic data such as cause of corneal perforation, surgical procedures, and visual outcomes were retrospectively analyzed.Results: The causes of corneal perforation (n=31 were divided into infectious (n=8, 26% and noninfectious (n=23, 74% categories. Infectious causes included fungal ulcer, herpetic stromal necrotizing keratitis, and bacterial ulcer. The causes of noninfectious keratopathy included corneal melting after removal of a metal foreign body, severe dry eye, lagophthalmos, canaliculitis, the oral anticancer drug S-1, keratoconus, rheumatoid arthritis, neurotrophic ulcer, atopic keratoconjunctivitis, and unknown causes. Initial surgical procedures included central large corneal graft (n=17, small corneal graft (n=7, and amniotic membrane transplantation (n=7. In two cases the perforation could not be sealed during the first surgical treatment and required subsequent procedures. All infectious keratitis required central large penetrating keratoplasty to obtain anatomical cure. In contrast, several surgical options were used for the treatment of noninfectious keratitis. After surgical treatment, anatomical cure was obtained in all cases. Mean postoperative best corrected visual acuity was better at 6 months (logMAR 1.3 than preoperatively (logMAR 1.8.Conclusion: Surgical therapies for corneal perforations in our hospital included central large lamellar/penetrating keratoplasty, small peripheral patch graft, and amniotic membrane transplantation.

    Guided imagery and music can reportedly reduce pain and anxiety during surgery, but no comparative study has been performed for cutaneous surgery to our knowledge. We sought to determine whether short-contact recorded guided imagery or relaxing music could reduce patient pain and anxiety, and surgeon anxiety, during cutaneous surgical procedures. Subjects were adults undergoing excisional surgery for basal and squamous cell carcinoma. Randomization was to guided imagery (n = 50), relaxing music (n = 54), or control group (n = 51). Primary outcomes were pain and anxiety measured using visual analog scale and 6-item short-form of the State-Trait Anxiety Inventory, respectively. Secondary outcomes were anxiety of surgeons measured by the 6-item short-form of the State-Trait Anxiety Inventory and physical stress of patients conveyed by vital signs, respectively. There were no significant differences in subjects' pain, anxiety, blood pressure, and pulse rate across groups. In the recorded guided imagery and the relaxing music group, surgeon anxiety was significantly lower than in the control group. Patients could not be blinded. Short-contact recorded guided imagery and relaxing music appear not to reduce patient pain and anxiety during excisional procedures under local anesthetic. However, surgeon anxiety may be reduced when patients are listening to such recordings. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    To evaluate the multilayer Gore-Tex patch as temporary coverage of deep, noninfectious corneal defects. Retrospective, interventional case series. University Medical Center Schleswig-Holstein, Kiel, Germany. Thirty-nine eyes of 38 patients with noninfectious, deep corneal defects. Underlying disorders included neurotrophic or immunologic ulcers in 37 eyes (94.9%) and traumatic defects in 2 eyes (5.1%). Intervention procedures: Corneal defects were covered with multiple Gore-Tex layers, of which the uppermost was sutured to the cornea. The Gore-Tex patch was kept in place until an appropriate corneal transplant was obtained and effective systemic immunosuppression was initiated. Long-term preservation of the eye, frequency of resuturing of the Gore-Tex patch, and best-corrected visual acuity. In 38 cases, the eye could be preserved. In 10 eyes, additional sutures were required. Before surgery, the mean best-corrected visual acuity (logMAR) was 1.14 ± 0.45 (20/250), and that at final follow-up was 1.13 ± 0.41 (20/250). The Gore-Tex patch remained in place 4 days to 32 months (mean, 6.4 ± 8.3 months) until corneal transplantation (27 eyes) or until an alternative way of defect coverage could be performed. Three eyes did not require further coverage after explantation of the Gore-Tex patch. In 6 eyes, either the Gore-Tex patch was kept in place or the patients died. Temporary coverage of deep corneal defects with multilayer Gore-Tex patches allows time until an appropriate corneal transplant is obtained. The technique is particularly useful in patients with underlying autoimmune disorders, because an effective systemic immunosuppression can be initiated before corneal transplantation.

    Patients undergoing coronary artery bypass graft (CABG) procedures have higher incidence of difficult laryngoscopy and intubation than general surgery population. Accurate prediction of difficult laryngoscopy in CABG patients is desirable to reduce the hemodynamic response and myocardial oxygen requirements. Recently, thyromental height test (TMHT) has been proposed as one of the highly sensitive and specific bedside tests to predict difficult airway. We, in our prospective observational study, evaluated the accuracy of the TMHT in predicting difficult laryngoscopy. A total of 345 patients undergoing CABG of either sex, in the age group of 35-80 years, American Society of Anesthesiologists 111, undergoing CABG, were studied. Airway assessment was performed with modified Mallampati test with the addition of thyromental distance, sternomental distance, and TMHT. Intraoperatively, direct laryngoscopy was done in accordance with Cormack and Lehane grade of laryngoscopy. The preoperative data and laryngoscopic findings were used together to evaluate the accuracy of TMHT. The sensitivity, specificity, positive and negative predictive values of other three tests were calculated according to standard formula. A total of 345 patients were in the group with mean age of study population at 56.7 (standard deviation 9.1) years (35-80 years). This study showed that almost all tests had good specificity, but sensitivity was poor. However, sensitivity of TMHT was 75% with accuracy of 95%. Receiver operating characteristic curve analysis of TMHT-derived cutoff was 52.17 which increased sensitivity to 81.25% and specificity to 92.3%. TMHT had a higher sensitivity compared to other tests along with good positive and negative predictive value and a very high specificity.

    Full Text Available Background: Patients undergoing coronary artery bypass graft (CABG procedures have higher incidence of difficult laryngoscopy and intubation than general surgery population. Accurate prediction of difficult laryngoscopy in CABG patients is desirable to reduce the hemodynamic response and myocardial oxygen requirements. Recently, thyromental height test (TMHT has been proposed as one of the highly sensitive and specific bedside tests to predict difficult airway. We, in our prospective observational study, evaluated the accuracy of the TMHT in predicting difficult laryngoscopy. Methodology: A total of 345 patients undergoing CABG of either sex, in the age group of 35–80 years, American Society of Anesthesiologists 111, undergoing CABG, were studied. Airway assessment was performed with modified Mallampati test with the addition of thyromental distance, sternomental distance, and TMHT. Intraoperatively, direct laryngoscopy was done in accordance with Cormack and Lehane grade of laryngoscopy. The preoperative data and laryngoscopic findings were used together to evaluate the accuracy of TMHT. The sensitivity, specificity, positive and negative predictive values of other three tests were calculated according to standard formula. Results: A total of 345 patients were in the group with mean age of study population at 56.7 (standard deviation 9.1 years (35–80 years. This study showed that almost all tests had good specificity, but sensitivity was poor. However, sensitivity of TMHT was 75% with accuracy of 95%. Receiver operating characteristic curve analysis of TMHT-derived cutoff was 52.17 which increased sensitivity to 81.25% and specificity to 92.3%. Conclusion: TMHT had a higher sensitivity compared to other tests along with good positive and negative predictive value and a very high specificity.

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

  7. Dental Occlusion and Ophthalmology: A Literature Review

    Stomatognathic system is strictly correlated to other anatomical regions; many studies investigated relationship between temporomandibular joint and posture, several articles describe cranio-facial pain from dental causes, such as trigger points. Until now less interest has been given to connections between dental occlusion and ophthalmology, even if they are important and involving. Clinical experience in dental practice claims that mandibular latero-deviation is connected both to eye dominance and to defects of ocular convergence. The trigeminal nerve is the largest and most complex of the twelve cranial nerves. The trigeminal system represents the connection between somitic structures and those derived from the branchial arches, collecting the proprioception from both somitic structures and oculomotor muscles. The intermedius nucleus of the medulla is a small perihypoglossal brainstem nucleus, which acts to integrate information from the head and neck and relays it on to the nucleus of the solitary tract where autonomic responses are generated. This intriguing neurophysiological web led our research group to investigate anatomical and functional associations between dental occlusion and vision. In conclusion, nervous system and functional pathways strictly connect vision and dental occlusion, and in the future both dentists and oculists should be more and more aware of this correlation for a better diagnosis and therapy.

    Most ophthalmologic disorders secondary to hypercoagulabe state are due to the confluence of congenital and adquired factors. A systematic workup is mandatory. Most of congenital coagulation disorders cause venous trombosis and are inherited autosomal dominantly. In order of frequency these are factor V Leiden mutation (activated protein C resistance), G20210A mutation of the prothrombin gen and protein C, protein S, and antithrombin III deficiencies. Sickle cell anemia can determine arerial and venous thrombosis. In relation with arterial occlusion, the markers most frequently involved are homcysteine fasting levels and the markers of antiphospholipid antibody syndrome. Both of them can also determine venous thrombosis. Several acquired factors can lead to hypoercoagulable state, especially hyperhomocysteinemia, antiphospholipid antibody syndrome, hepatic disease, alcohol and tobacco intake, oral contraceptives, immobilization, surgeries and malignancies. In central venous occlusion is only necessary to rule out hyperhomocysteinemia and antiphospholipid antibody syndrome in young patients without known risk factors. In central artery occlusion, hypercoagulable workup is only recommended for patients less than 50 years-old with unknown emboli source. In this cases protein C, protein S, and antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome will ruled out. In non arteritic ischemic optic neuropathy hypercoagulable work up is not necessary. In amaurosis fugax without known emboli source, it is recommended to rule out etiologies of arterial occlusion, especially antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome.

    Full Text Available Botulinum neurotoxin (BoNT is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines or crow’s feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use. BoNT has gained widespread use in a variety of ophthalmic diseases. The effect of BoNT is temporary, but the therapeutic benefit is usually maintained even after repeated injections. Treatment is usually well tolerated. Complications and side effects associated with the treatment are rare and temporary. Complications occur due to weakness (chemodenervation of adjacent muscle groups, immunological mechanisms and injection technique. Current therapeutic indications, doses, complications and contraindications of BoNT use in the following disorders related to ophthalmology were investigated: aesthetic use, strabismus, blepharospasm, hemifacial spasm, eyelid retraction, entropion, lacrimal hypersecretion syndrome, and facial paralysis.

    2014-01-01

    Facial nerve palsy is associated with significant morbidity and can have different etiologies. The most common causes are Bell’s palsy, Ramsay–Hunt syndrome and trauma, including surgical trauma. Incidence varies between 17 and 35 cases per 100,000. Initial evaluation should include accurate clinical history, followed by a comprehensive investigation of the head and neck, including ophthalmological, otological, oral and neurological examination, to exclude secondary causes. Routine laboratory testing and diagnostic imaging is not indicated in patients with new-onset Bell’s palsy, but should be performed in patients with risk factors, atypical cases or in any case without resolution within 4 months. Many factors are involved in determining the appropriate treatment of these patients: the underlying cause, expected duration of nerve dysfunction, anatomical manifestations, severity of symptoms and objective clinical findings. Systemic steroids should be offered to patients with new-onset Bell’s palsy to increase the chance of facial nerve recovery and reduce synkinesis. Ophthalmologists play a pivotal role in the multidisciplinary team involved in the evaluation and rehabilitation of these patients. In the acute phase, the main priority should be to ensure adequate corneal protection. Treatment depends on the degree of nerve lesion and on the risk of the corneal damage based on the amount of lagophthalmos, the quality of Bell’s phenomenon, the presence or absence of corneal sensitivity and the degree of lid retraction. The main therapy is intensive lubrication. Other treatments include: taping the eyelid overnight, botulinum toxin injection, tarsorrhaphy, eyelid weight implants, scleral contact lenses and palpebral spring. Once the cornea is protected, longer term planning for eyelid and facial rehabilitation may take place. Spontaneous complete recovery of Bell’s palsy occurs in up to 70% of cases. Long-term complications include aberrant regeneration

    Accompany with dramatically growth of large-scale biological databases (such as human genome sequence), improvement of life science and development of international clinical trials, science offers great potential for improving health care through precision medicine. As a hot topic recently, precision medicine might launch a revolution of the methodology in medical research. How to achieve precision medicine in clinical ophthalmology by means of biological data mining is a challenge for ophthalmologist-scientists. The best approach for advanced individual medicine is to buildup the digital ophthalmology, which includes human eye biobank, national biological databases network, clinical department, basic research lab, and international clinical trial center. The system of digital ophthalmology could explore the methods for ophthalmology research, integrate the source of eye biologic databases, promote international cooperation, and thus eventually supply the opportunity for translational medicine.

    considered as an adjunct to cause-related periodontal therapy. The kind of surgery performed, the number of sites included and the moment at which it should performed is decided after evaluating for the initial cause-related therapy results. The ultimate objective of periodontal surgical treatment is the long term preservation of the periodontium. Periodontal surgery can contribute to this end creating accessibility for an adequate scaling and root planning therefore restoring the gingival morphology which facilitates the automatic plaque control of the patient. Developed surgical techniques must be evaluated on the basis of their potential to facilitate the elimination of subgingival deposits, as well as facilitate plaque control and thus improve the long term preservation of the periodontium. In the present article the authors review the basis of surgical periodontal treatment as well as related concepts and considerations, objectives, indications and contraindications, procedures and factors that determine the selection of one or the other surgical technique.

    Due to the strong reduction in the length of hospital stays in the last decade, the period of in-hospital postoperative care is limited. After discharge from the hospital, guidance and monitoring on recovery and resumption of (work) activities are usually not provided. As a consequence, return to normal activities and work after surgery is hampered, leading to a lower quality of life and higher costs due to productivity loss and increased health care consumption. With this study we aim to evaluate whether an eHealth care program can improve perioperative health care in patients undergoing commonly applied abdominal surgical procedures, leading to accelerated recovery and to a reduction in costs in comparison to usual care. This is a multicenter randomized, single-blinded, controlled trial. At least 308 patients between 18 and 75 years old who are on the waiting list for a laparoscopic cholecystectomy, inguinal hernia surgery, or laparoscopic adnexal surgery for a benign indication will be included. Patients will be randomized to an intervention or control group. The intervention group will have access to an innovative, perioperative eHealth care program. This intervention program consists of a website, mobile phone app, and activity tracker. It aims to improve patient self-management and empowerment by providing guidance to patients in the weeks before and after surgery. The control group will receive usual care and will have access to a nonintervention (standard) website consisting of the digital information brochure about the surgical procedure being performed. Patients are asked to complete questionnaires at 5 moments during the first 6 months after surgery. The primary outcome measure is time to return to normal activities based on a patient-specific set of 8 activities selected from the Patient-Reported Outcomes Measurement Information System (PROMIS) physical functioning item bank version 1.2. Secondary outcomes include social participation, self-rated health

  1. Surgical Lasers In Gynecology

    Schellhas, Helmut F.; Barnes, Alfonso E.

    1982-12-01

    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

    To address the use of and knowledge about skills assessment and competency-based training in cataract surgery in European Board of Ophthalmology (EBO) member countries. A survey was emailed directly to all directors of the European societies in ophthalmology. The survey included queries about criteria to undergo training in cataract surgery, regulation of education in cataract surgery, and skills assessment and training methods. In addition, all Danish Eye Departments were further asked to what extent they find assessment tools useful, if competency-based training in cataract surgery would be an improvement, and if an assessment tool would be considered for use in future training of cataract surgeons. Training in cataract surgery in EBO countries is very diverse; although some EBO countries consider it mandatory in residency, most do not. In EBO countries where training is mandatory and regulated by the local health authority, the use of skills assessment tools and competency-based education are more prevalent (e.g., U.K., Ireland, Switzerland, and the Netherlands). In Denmark, training in cataract surgery is not mandatory, and none of the eye departments used assessment scores to evaluate their trainees; 63% did not believe that using assessment tools would improve the outcome of surgical training, and less than one-third would consider frequent use of assessment tools in the future. General unawareness and scepticism toward objective structured assessment of technical skills and a considerable heterogeneity in concept and organization of training in cataract surgery across EBO countries is an issue to address.

    To analyze the self-citation rate (SCR) of ophthalmology journals, determine its possible effect on a journal's impact factor (IF) and compare the SCR of subspecialty journals versus general ophthalmology journals. A retrospective consecutive study of ophthalmology journals listed in the Journal Citations Report (JCR) 2013. We retrieved these parameters from each journal's report: IF, total citations, self-citations, SCR and IF without self-citations (corrected IF). A significant correlation was detected between the number of self-citations and publications (R(2) = 86.3, p = 0.000). Subspecialty journals had a significantly higher SCR than general journals (p = 0.017). No significant difference was found in terms of IF and corrected IF between general and subspecialty journals (p = 0.260 and p = 0.108, respectively). No significant correlation between IF and SCR was detected (p = 0.099). The corrected IF was inversely correlated with SCR (R(2) = -32.6, p = 0.013). An inverse correlation was detected between SCR and IF in the 29 ophthalmology journals with the lowest IF (R(2) = -57.3, p = 0.001). Unlike other fields of medicine, the IF of an ophthalmology journal does not correlate with its SCR. Self-citation is found more often in journals with a low corrected IF and is inversely correlated with IF in the bottom half. © 2014 S. Karger AG, Basel.

    1. With some exceptions, those who choose ophthalmology as a career may approximate the general population in innate manual dexterity. 2. Many factors other than manual dexterity influence the development of surgical skills by residents. 3. If dexterity testing is to be used, the addition or inclusion of tests for spatial aptitudes may be more helpful than simple dexterity tests alone. The predictive value of such tests for surgical performance would need vertification. 4. The development of a special test directly related to handling surgical instruments, to cutting, and to sewing (the criteria) may be more practical than the ones used in this study.

    2016-01-01

    Background Due to the strong reduction in the length of hospital stays in the last decade, the period of in-hospital postoperative care is limited. After discharge from the hospital, guidance and monitoring on recovery and resumption of (work) activities are usually not provided. As a consequence, return to normal activities and work after surgery is hampered, leading to a lower quality of life and higher costs due to productivity loss and increased health care consumption. Objective With this study we aim to evaluate whether an eHealth care program can improve perioperative health care in patients undergoing commonly applied abdominal surgical procedures, leading to accelerated recovery and to a reduction in costs in comparison to usual care. Methods This is a multicenter randomized, single-blinded, controlled trial. At least 308 patients between 18 and 75 years old who are on the waiting list for a laparoscopic cholecystectomy, inguinal hernia surgery, or laparoscopic adnexal surgery for a benign indication will be included. Patients will be randomized to an intervention or control group. The intervention group will have access to an innovative, perioperative eHealth care program. This intervention program consists of a website, mobile phone app, and activity tracker. It aims to improve patient self-management and empowerment by providing guidance to patients in the weeks before and after surgery. The control group will receive usual care and will have access to a nonintervention (standard) website consisting of the digital information brochure about the surgical procedure being performed. Patients are asked to complete questionnaires at 5 moments during the first 6 months after surgery. The primary outcome measure is time to return to normal activities based on a patient-specific set of 8 activities selected from the Patient-Reported Outcomes Measurement Information System (PROMIS) physical functioning item bank version 1.2. Secondary outcomes include social

METHODS: The sample of this systematic review comprised the two Brazilian journals of ophthalmology indexed at Science Citation Index Expanded and six of the foreign journals of ophthalmology with highest Impact Factor® according ISI. All clinical trials (CTs published from January 2009 to December 2010 at the Brazilians journals and a 1:1 randomized sample of the foreign journals were included. The primary outcome was the number of citations through the end of 2011. Subgroup analysis included language. The secondary outcome included likelihood of citation (cited at least once versus no citation, and presence or absence of CONSORT statement indicators. RESULTS: The citation counts were statistically significantly higher (P<0.001 in the Foreign Group (10.50 compared with the Brazilian Group (0.45. The likelihood citation was statistically significantly higher (P<0.001 in the Foreign Group (20/20 - 100% compared with the Brazilian Group (8/20 - 40%. The subgroup analysis of the language influence in Brazilian articles showed that the citation counts were statistically significantly higher in the papers published in English (P<0.04. Of 37 possible CONSORT items, the mean for the Foreign Group was 20.55 and for the Brazilian Group was 13.65 (P<0.003. CONCLUSION: The number of citations and the quality of reporting of clinical trials in Brazilian journals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

    Major vascular injuries in extremities are rare and constitute problems for surgeons and their sequelae strongly influence remote future of the patients. The aim of study is to evaluate surgical treatment of vascular injuries in extremities and some aspects of quality of life. Since 1983 until 2002 sixty four patients with vascular limbs injuries were treated in the department. Remote evaluation has been performed in 33 persons. Severity of limb injuries was measured by Mangled Extremity Severity Score (MESS). In 20 patients (60.6%) very good and good recent results were obtained, satisfactory in 24.2% and bad results in 15.2% persons. Evaluation of functional status has been made by means of locomotion test and Jebsen-Taylor's test, social approval questionnaire, depression Beck's scale, the scale of hypochondria and by an original questionnaire to evaluate the quality of life. As considerable interdependence has been found between the functional status and the following factors: injury severity expressed in MESS (p < 0.01), clinic reception procedure (p < 0.001), ischemia time (p < 0.01), coincidence of other injuries (fractures and dislocations, muscle, tendon and nerve lesions) (p < 0.01), limb amputation (p < 0.01). Hand function significantly influences the quality of life. Patients who were in shock after trauma in the remote assessment showed susceptibility to the lowered mood and depression (p < 0.05). Quality of life is strongly connected with the features of personality, correlating mainly with the mood and tendencies of concentration upon somatic symptoms. Function of the hand influences strongly the quality of life. Amputated patients may in spite of their crippling limitations are able to adapt to everyday life.

    A retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database, a national representative database in Japan. The aim of this study was to examine seasonal variations in the risk of reoperation for surgical site infection (SSI) following spinal fusion surgery. Although higher rates of infection in the summer than in other seasons were thought to be caused by increasing inexperience of new staff, high temperature, and high humidity, no studies have examined seasonal variations in the risk of SSI following spinal fusion surgery in the country where medical staff rotation timing is not in summer season. In Japan, medical staff rotation starts in April. We retrospectively extracted the data of patients who were admitted between July 2010 and March 2013 from the DPC database. Patients were included if they were aged 20 years or older and underwent elective spinal fusion surgery. The primary outcome was reoperation for SSI during hospitalization. We performed multivariate analysis to clarify the risk factors of primary outcome with adjustment for patient background characteristics. We identified 47,252 eligible patients (23,659 male, 23,593 female). The mean age of the patients was 65.4 years (range, 20-101 yrs). Overall, reoperation for SSI occurred in 0.93% of the patients during hospitalization. The risk of reoperation for SSI was significantly higher in April (vs. February; odds ratio, 1.93; 95% confidence interval, 1.09-3.43, P = 0.03) as well as other known risk factors. In subgroup analysis with stratification for type of hospital, month of surgery was identified as an independent risk factor of reoperation for SSI among cases in an academic hospital, although there was no seasonal variation among those in a nonacademic hospital. This study showed that month of surgery is a risk factor of reoperation for SSI following elective spinal fusion surgery, nevertheless, in the country where medical staff rotation timing is not in

    The chiasmal syndrome has distinct ophthalmological features such as visual field loss, optic disc changes, decrease in visual acuity, ocular motor disturbances and exophthalmos. However, the pathological processes in the chiasmal region often give rise to differential diagnostic problems. Before the era of computer tomography (CT) these processes could only be visualized by means of indirect or invasive examination techniques. After introduction of computer tomography these processes could be identified much more easily. The ophthalmological findings are discussed. The most frequent causes of chiasmal syndrome are demonstrated on CT scan. The neuro-radiological differential diagnosis of an enlarged sella turcica is given.

    To evaluate the research productivity of Canadian ophthalmology departments in terms of research volume, impact, funding, and cost-efficiency, and compare these measures with the top 6 U.S. departments. Systemic review. Using the Web of Science, we obtained the number of peer-reviewed research articles and citations in which an author listed an ophthalmology department (or affiliated university or hospital) from 2001 to 2010 in the top 10 ophthalmology and vision sciences journals, as well as the Canadian Journal of Ophthalmology. Federal research funding received from the Canadian Institutes of Health Research and National Institutes of Health was also obtained. The 3 universities that produced the highest number of articles were the University of Toronto (UofT), McGill University, and the University of British Columbia (UBC). UofT also produced the largest number of citations, followed by UBC and Dalhousie University. For the number of citations per article, the top 3 were the University of Ottawa, Dalhousie University, and the University of Calgary. McGill University, the University of Montreal, and UofT received the most federal funding. The 3 Canadian universities with the lowest funding (cost) per article were UofT, UBC, and McMaster University. The top contributors to the Canadian Journal of Ophthalmology from 2001 to 2010 were UofT, the University of Ottawa, and McGill University. Larger Canadian departments tended to generate higher research volume and obtained more federal funding, but smaller departments also contributed significantly, and sometimes surpassed larger departments, in terms of research impact and cost-efficiency. The top 6 U.S. departments generated higher research volume and received more federal research funding than their Canadian counterparts. However, when research impact and cost-efficiency were examined, Canadian departments performed similar to the top U.S. departments. Copyright © 2013 Canadian Ophthalmological Society. Published

    Full Text Available Daniel P Schwartz, Matthew S RobbinsDepartment of Neurology, Montefiore Headache Center, Albert Einstein College of Medicine, Bronx, NY, USAAbstract: Headache is an extraordinarily common complaint presenting to medical practitioners in all arenas and specialties, particularly primary care physicians, neurologists, and ophthalmologists. A wide variety of headache disorders may manifest with a myriad of neuro-ophthalmologic symptoms, including orbital pain, disturbances of vision, aura, photophobia, lacrimation, conjunctival injection, ptosis, and other manifestations. The differential diagnosis in these patients is broad and includes both secondary, or symptomatic, and primary headache disorders. Awareness of the headache patterns and associated symptoms of these various disorders is essential to achieve the correct diagnosis. This paper reviews the primary headache disorders that prominently feature neuro-ophthalmologic manifestations, including migraine, the trigeminal autonomic cephalalgias, and hemicrania continua. Migraine variants with prominent neuro-ophthalmologic symptoms including aura without headache, basilar-type migraine, retinal migraine, and ophthalmoplegic migraine are also reviewed. This paper focuses particularly on the symptomatology of these primary headache disorders, but also discusses their epidemiology, clinical features, and treatment.Keywords: headache, migraine, trigeminal autonomic cephalalgias, neuro-ophthalmologic, aura, photophobia

    Neuro-ophthalmology, as an interdisciplinary, covers at least three disciplines- ophthalmology, neurology and neurosurgery. With limited knowledge in each discipline, doctors often make misdiagnoses for neuro-ophthalmology diseases. Therefore, it is imperative to abandon the distinction between disciplines and combine all the knowledge to diagnose and treat patients in patterns of holistic integrated medicine in order to effectively improve the diagnosis and treatment of neuro-ophthalmology.

    Full Text Available Epidemiological differences can be found between Brazilian and European valvular heart disease patients. The prevalence of heart valve diseases due to rheumatic disease is significantly higher in the Brazilian compared with the European population. Therefore, they could have different risks during and after cardiac surgery. The aim of this study was to evaluate the applicability of the additive and logistic EuroSCORE and EuroSCORE II in a cohort of high-risk patients with valvular heart disease of predominantly rheumatic aetiology submitted to surgery.Between 1 February and 30 December 2009, 540 consecutive patients scheduled for valvular heart surgery were included in this study. In this set of patients, we examined the performance of the additive, logistic, and EuroSCORE II models for predicting in-hospital mortality. Calibration of each model was assessed by comparing predicted and observed in-hospital mortality and by the goodness of fit of the Hosmer-Lemeshow chi-square test. Discrimination performance of the model was evaluated with the receiver operating characteristic (ROC curve analysis.The mean age was 56 ± 16 years, 50.6% were female, and the mortality rate was 16.0% (6.0% in elective surgery and 34.0% in emergency/urgency surgery. Mortality rates were estimated according to the additive and logistic EuroSCORE and EuroSCORE II at 6.1%, 8.7%, and 4.3%, respectively. The AUC was 0.76 (95% confidence interval [95% CI] 0.70-0.81 for the additive EuroSCORE, 0.76 (95% CI 0.70-0.81 for the logistic EuroSCORE and 0.81 (95% CI 0.76-0.86 for EuroSCORE II. Hosmer-Lemeshow goodness-of-fit statistics were P = 0.52, P = 0.07, and P = 0.12 for additive, logistic EuroSCORE, and EuroSCORE II.In this cohort of Brazilian patients with valvular heart disease submitted to surgical procedure, the EuroSCORE models had a good discriminatory capacity; however, the calibration was compromised because of an underestimation of the mortality rate.

To achieve the strengthening of the corneal tissue irradiation with ultraviolet light And is combined with the use of Riboflavin. Riboflavin plays a role of a photosensitizer in the process of photopolymerization and ultraviolet irradiation increases the formation of inter — and intrafibrillary covalent bonds.

The lack of effect of routine procedures is defined as the increase in refractive power of the cornea by 1 Diopter. after treatment and observed in 8.1‑33.3 % of cases. A relatively frequent complication of the standard procedure of crosslinking (10‑90 % is corneal haze. A number of cases of infectious keratitis, including bacterial, protozoan and fungal forms is registered. Rare complications after standard procedure of crosslinking are diffuse lamellar keratitis, melting corneal and endothelial-epithelial dystrophy. After instillation of Riboflavin its diffusion in the corneal stroma is limited by a dense contacts between epithelial cells, resulting in crosslinking often resort to preliminary scarification of epithelium. However, this manipulation is the cause of the complications of crosslinking, as intra — and postoperative pain, infectious keratitis and lethargic regeneration of the epithelium. The permeability of the epithelium for Riboflavin can be enhanced in several ways, for example, modifying physico-chemical properties of Riboflavin molecules or increasing the permeability of the epithelium, for example, by instillation of a 40 % strength solution of glucose. It was shown that the conducting electrophoresis with Riboflavin for

    Although it has been over 15 years since the first recorded use of a robot for a surgical procedure, the field of medical robotics is still an emerging one that has not yet reached a critical mass. Although robots have the potential to improve the precision and capabilities of physicians, the number of robots in clinical use is still very small. In this review article, we begin with a short historical review of medical robotics, followed by an overview of clinical applications where robots have been applied. The clinical applications are then discussed; they include neurosurgery, orthopedics, urology, maxillofacial surgery, radiosurgery, ophthalmology, and cardiac surgery. We conclude with a listing of technology challenges and research areas, including system architecture, software design, mechanical design, imaging compatible systems, user interface, and safety issues.

Materials and Methods: Consecutive surgical records of phaco performed from March 2009 to Sept 2011 by four residents without previous ECCE experience were retrospectively reviewed. The completion rate of the first 30 procedures by each resident was calculated. The main intraoperative phaco parameter records for the first 30 surgeries by each resident were compared with those for their last 30 surgeries. Intraoperative complications in the residents′ procedures were also recorded and analyzed. Results: A total of 1013 surgeries were performed by residents. The completion rate for the first 30 phaco procedures was 79.2 μ 5.8%. The main reasons for halting the procedure were as follows: Anterior capsule tear, inability to crack the nucleus, and posterior capsular rupture during phaco or cortex removal. Cumulative dissipated energy of phaco power used during the surgeries was significantly less in the last 30 cases compared with the first 30 cases (30.10 μ 17.58 vs. 55.41 μ 37.59, P = 0.021. Posterior capsular rupture rate was 2.5 μ 1.2% in total (10.8 μ 4.2% in the first 30 cases and 1.7 μ 1.9% in the last 30 cases, P = 0.008; a statistically significant difference. Conclusion:The step-by-step training program might be a necessary process for a resident to transit from dependence to a self-supported operator. It is also an essential middle step between wet lab training to performing the entire phaco procedure on the patient both effectively and safely.

    Basic knowledge and skills are cornerstone of the diagnosis and treatment of neuro-ophthalmology diseases in ophthalmology practice. Due to the interdisciplinary features of neuro-ophthalmology, neuro-anatomy, neuro-physiology related to eyes, neuro-image and neuro-electrodiagnosis, these should be included in the education for the ophthalmologist. Special attention should be paid to training on capability of logically thinking in neuro-ophthalmology. Multiple ways can be used for the education of ophthalmologists and neurologists for the enhancement of basic knowledge and skills of neuro-ophthalmology in China.

    Full Text Available Purpose To report the surgical technique, procedural outcomes, and feasibility of simultaneous bilateral Video Endoscopic Inguinal Lymphadenectomy (VEIL in the management of patients with indication for inguinal lymphadenectomy. Surgical Technique: VEIL was applied in all patients using the oncological landmarks (the adductor longus muscle medially, the sartorius muscle laterally and the inguinal ligament superiorly. A 1.5 cm incision was made 2 cm distally to the lower vertex of the femoral triangle. A second incision was made 2 cm proximally and 6 cm medially. Two 10 mm Hasson trocars were inserted in these incisions and the working space was insufflated with CO2 at 5-15 mmHg. The final trocar was placed 2 cm proximally and 6 cm laterally from the first port. Results: A total of 5 VEIL procedures in 3 patients were performed. Two patients underwent simultaneous bilateral VEIL while another underwent simultaneous bilateral surgery with VEIL on the right and open lymphadenectomy on the left side due to an enlarged node. All laparoscopic procedures were successfully performed without conversion and maintained the oncological templates. One lymphocele occurred in the patient who underwent the open procedure. None of the patients presented with skin necrosis after the procedure. Mean number of nodes retrieved was 6 from each side and 2 patients presented with positive inguinal nodes. After one year of follow-up no recurrences were observed. Conclusion: Simultaneous lymphadenectomy procedures are feasible. Improvement in operative and anesthesia time could decrease the morbidity associated with inguinal lymphadenectomy while maintaining the oncological principles.

    Optical coherence tomography (OCT) has revolutionised ophthalmology. Due to modern instruments with extremely high resolution there are more and more applications also in neuro-ophthalmological disorders. This review gives an overview on typical changes in OCT for the following diseases: autosomal dominant optic atrophy, Leber hereditary optic neuropathy, toxic, traumatic and compressive optic neuropathy, optic nerve drusen, anterior ischaemic optic neuropathy, optic disc pit, papilledema, optic neuritis (isolated or associated with multiple sclerosis or neuromyelitis optica), neurodegenerative diseases and hereditary retinal diseases. A diagnosis exclusively based on an OCT examination is not always possible, but in several diseases there are pathognomonic changes that directly lead to the correct diagnosis. Particularly with the often complex settings in neuro-ophtalmology the OCT should be seen as a supplementary modality and not as a replacement for other techniques.

    Full Text Available Drug delivery to the inner part of the eye is still a problem in treatment of ocular disease. Iontophoresis has been used in the field of medicine for many years. This technique consists of applying a weak electrical current to drive charged drug molecules across tissue barriers. Transcorneal iontophoresis delivers a high concentration of drug to the anterior segment of the eye (cornea, aqueous humor, ciliary body, iris, and lens, for the treatment of anterior segment diseases. There are different types of iontophoresis such as ophthalmic, transdermal, transungual, oral, buccal, and transnasal. The benefit of iontophoretic drug delivery in ophthalmology lays in its capacity to provide high drug tissue concentration safely, while minimizing the systemic drug exposure. This review summarizes basics of ocular iontophoresis and iontophoretic device, trans corneal and transscleral iontophoresis, and the applications of iontophoresis in ophthalmology.

Eligible apps were identified and downloaded into the iPad tablet computers, and then categorized according to the apps' initial contents and our using experiences. Methods about how to use the iPad's built-in functions of instant video call(FaceTime®and automatic data storage technology(iCloud®were also described together with the apps. Other operating systems of Microsoft's Window Phone and Google's Android were also searched for ophthalmology-relevant apps.RESULTS: The keywords for searching on the Apple's App Store were “ophthalmology” and “eye”. And we could found 111 eligible apps with the former keyword, and 452 ones with the latter one. The integrated uses of the iPad tablet computer were then categorized into five aspects. Based on our clinical practice, we finally summarized the advantages and disadvantages of the iPad tablet computer for ophthalmic practices. However, ophthalmology-relevant apps were found to be very limited in number on the other two platforms.CONCLUSION: The integrated use of self built-in apps and third-party apps can facilitate our clinical work in examination, telemedicine, reference, disease education and literature searching. More studies are needed to verify its validation and reliability in the professional fields, especially eye examinations.

  2. The foundation of experimental ophthalmology by Theodor Leber.

    Jaeger, W

    1988-01-01

    Theodor Leber grew up in Heidelberg as the son of a professor of Romance languages. Initially he planned to study natural sciences. Bunsen's advice led him to medicine. During his studies he succeeded in solving a competition problem posed by Helmholtz in the medical department. A short period of practical work in the eye hospital of Knapp was unsatisfactory. In Vienna with the physiologist Carl Ludwig, he was able in 1863/64, at the age of only 24 years, to demonstrate the blood circulation of the eye by color injections into the arteries and veins. Since that time the schematic drawings of his results can be found in every textbook of ophthalmology. On the occasion of the congress of the German Ophthalmological Society in Heidelberg in 1864, Theodor Leber reported on these findings and met with immense approval. In 1864-67 he followed an invitation as coworker of Liebreich to Paris; in 1867 he became A.v. Graefe's coworker in Berlin; in 1871 he moved to Göttingen, which became the first eye clinic with a laboratory for experimental investigations. The second epoch-making discovery accomplished by Leber was the detection of the fluid exchange in the eye. These results have also been confirmed by modern methods. Therefore, Theodor Leber can be called the father of experimental ophthalmology.

    Electronic storage of patient-related data will replace paper-based patient records in the near future. Because of the high visualization needed in ophthalmology integrated electronic data storage and usage will be very useful. Chronic diseases like glaucoma, macular degeneration and diabetic retinopathy would benefit from long-term data storage and analysis. Unfortunately there are nearly no widely accepted systems available providing these options. Another important point is the simplification of existing diagnostic procedures and nomenclature on an international level. Increasing mobility of patients requires a better portability of existing medical examination data between different physicians. This is the only way to provide continuously high levels of quality in patient care and to simultaneously reduce costs and prevent unnecessary secondary examinations.

    There has been an increasing use of national databases to conduct orthopaedic research. Questions regarding the validity and consistency of these studies have not been fully addressed. The purpose of this study was to test for similarity in reported measures between two national databases commonly used for orthopaedic research. A retrospective cohort study of patients undergoing lumbar spinal fusion procedures during 2009 to 2011 was performed in two national databases: the Nationwide Inpatient Sample and the National Surgical Quality Improvement Program. Demographic characteristics, comorbidities, and inpatient adverse events were directly compared between databases. The total numbers of patients included were 144,098 from the Nationwide Inpatient Sample and 8434 from the National Surgical Quality Improvement Program. There were only small differences in demographic characteristics between the two databases. There were large differences between databases in the rates at which specific comorbidities were documented. Non-morbid obesity was documented at rates of 9.33% in the Nationwide Inpatient Sample and 36.93% in the National Surgical Quality Improvement Program (relative risk, 0.25; p databases in the rates at which specific inpatient adverse events were documented. Sepsis was documented at rates of 0.38% in the Nationwide Inpatient Sample and 0.81% in the National Surgical Quality Improvement Program (relative risk, 0.47; p database studies become more prevalent in orthopaedic surgery, authors, reviewers, and readers should view these studies with caution. This study shows that two commonly used databases can identify demographically similar patients undergoing a common orthopaedic procedure; however, the databases document markedly different rates of comorbidities and inpatient adverse events. The differences are likely the result of the very different mechanisms through which the databases collect their comorbidity and adverse event data. Findings highlight

    Lung transplantation in rats is technically difficult and results may vary. The non-suture cuff technique (non-suture [NS]), which involves using a cuff for anastomoses of vessels and airways, is commonly utilized to perform transplant procedures. However, the standard bronchial cuff may occlude the lumen, resulting in diminished graft survival. In contrast, the non-suture cuff technique for vascular anastomoses with bronchial suturing (bronchial suture [BS]), although more technically difficult, is known to have prolonged bronchial patency. We developed a "modified" NS technique that uses a larger and longer cuff for anastomoses and compared the efficacy of this procedure to the BS technique for lung transplantation. The BS procedure was performed in 146 transplant procedures. The modified NS procedure, which uses a larger cuff than the standard NS procedure, was performed in 113 procedures. Although total ischemic times were comparable, the total operation time in the NS group was significantly shorter than in the BS group (p technique is widely acknowledged to provide prolonged patency of bronchial anastomosis, graft survival in the NS group was observed up 17 months post-transplant. These data show that the NS technique, which is less technically difficult, results in shorter operative times compared with the BS procedure, and results in durable anastomoses of lung grafts.

    The American Academy of Ophthalmology and Otolaryngology grew steadily during its 82-year existence, and since 1979, the American Academy of Ophthalmology has had an accelerated increase in membership and activity. In 1995, as the Academy approached its centennial, the AAO had more than 20,000 members and an annual budget of more than +26 million. Total registration for the 1994 Annual meeting was slightly more than 27,000, an all-time high. Instruction Courses numbered 450,300 scientific papers were presented, and 130 posters were displayed. The original postgraduate course in 1921 served as the predecessor to the more than 700 hours of instruction presented at the 1994 Annual Meeting. The original committee of four was the predecessor of what has become the Secretariats of the Academy. The popular Home Study Courses were the forerunners of the Academy's programs, formulated and supervised by the Education Secretaries. The Clinical Education Programs include the Basic and Clinical Science Courses, Focal Points, Continuing Ophthalmic Video Education, Manuels, Regional Update Courses, Special Focus/Skills Courses, Monographs, PROvision, slide scripts, and other programs produced for allied health personnel, medical students, and other physicians. The Secretaries originate, produce, and oversee all the important functions of the Academy. The individuals who have served the Academy as Secretaries through the years have been dedicated volunteers. Their contributions have been incalculable. In recent years, the various Secretaries have been ably assisted by Associate Secretaries, Advisory Committees, and Subcommittees, spreading the workload of each Secretary. Credit for the success of the Academy's endeavors, while under the guidance of the Secretaries, also must be given to the Academy's many committee chairs and committee members who have diligently worked to achieve their goals and objectives. In 1995, the Executive Vice President, the 11 Secretaries, and the Editor

    Full Text Available Purpose: To study the surgical outcome of triple procedure as penetrating keratoplasty (PKP with conventional extra capsular cataract extraction (ECCE with posterior chamber intraocular lens (PCIOL implantation in patients with both central corneal opacity and advanced cataract at rural set up. Introduction: When corneal opacity and cataract present together then well-established and effective triple procedure is indicated. Prognosis for a clear graft is good in triple, as graft endothelium does not touch the hard nucleus which may occur in two steps or sequential surgery. It provides faster visual rehabilitation. Being single step procedure it reduces patient’s hospital stay, postoperative care and follows up visits. Methodology: In this hospital based observational , three years longitudinal study, we studied the surgical outcome of relatively rare one step triple procedure as PKP with conventional ECCE with PCIOL implantation in sulcus or in bag, in patients with both central corneal opacity and advanced cataract at rural set up. The outcome measures included graft clarity on slit lamp, postoperative unaided visual acuity with Snellen’s chart and the occurrence of postoperative complications after taking IEC permission and informed written consent in local language from study patients. Results: Out of 13 study patients mean age was 61.15yrs (Range50-80yrs. Follow up range was 9-34 months. At final follow up 9 patients (69.23% had clear grafts and 61.52% patients gained visual acuity >6/24. Graft failure was the most common post operative complication in 30.76% followed by Posterior capsular opacification (PCO in 15.38% patients which was treated well with YAG laser capsulotomy. Conclusion: Triple procedure gives good results in respect to graft clarity, unaided vision, and faster rehabilitation.

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    2014-12-01

    In ophthalmology, it is now common practice to record every surgical procedure and to archive the resulting videos for documentation purposes. In this paper, we present a solution to automatically segment and categorize surgical tasks in real-time during the surgery, using the video recording. The goal would be to communicate information to the surgeon in due time, such as recommendations to the less experienced surgeons. The proposed solution relies on the content-based video retrieval paradigm: it reuses previously archived videos to automatically analyze the current surgery, by analogy reasoning. Each video is segmented, in real-time, into an alternating sequence of idle phases, during which no clinically-relevant motions are visible, and action phases. As soon as an idle phase is detected, the previous action phase is categorized and the next action phase is predicted. A conditional random field is used for categorization and prediction. The proposed system was applied to the automatic segmentation and categorization of cataract surgery tasks. A dataset of 186 surgeries, performed by ten different surgeons, was manually annotated: ten possibly overlapping surgical tasks were delimited in each surgery. Using the content of action phases and the duration of idle phases as sources of evidence, an average recognition performance of Az = 0.832 ± 0.070 was achieved.

    To reduce the incidence of postoperative pharyngolaryngeal adverse events, laryngeal mask airway (LMA) manufacturers recommend maximum cuff pressures not exceeding 60 cmH₂O. We performed a prospective randomised study, comparing efficacy and adverse events among patients undergoing laparoscopic surgical procedures who were allocated randomly into low (limiting 25 cmH₂O, L group) and high (at 60 cmH₂O, H group) LMA cuff pressure groups with LMA Supreme. Postoperative pharyngolaryngeal adverse events were evaluated at discharge from postanaesthetic care unit (PACU) (postoperative day 1, POD 1) and 24 hours after discharge from PACU (postoperative day 2, POD 2). All patients were well tolerated with LMA without ventilation failure. Before pneumoperitoneum, cuff volume and pressure and oropharyngeal leak pressure (OLP) showed significant differences. Postoperative sore throat at POD 2 (3 versus 12 patients) and postoperative dysphagia at POD 1 and POD 2 (0 versus 4 patients at POD 1; 0 versus 4 patients at POD 2) were significantly lower in L group, compared with H group. In conclusion, LMA with cuff pressure limiting 25 cmH₂O allowed both efficacy of airway management and lower incidence of postoperative adverse events in laparoscopic surgical procedures. This clinical trial is registered with KCT0000334.

    Unbiased evaluation of trauma core competency procedures is necessary to determine if residency and predeployment training courses are useful. We tested whether a previously validated individual procedure score (IPS) for individual procedure vascular exposure and fasciotomy (FAS) performance skills could discriminate training status by comparing IPS of evaluators colocated with surgeons to blind video evaluations. Performance of axillary artery (AA), brachial artery (BA), and femoral artery (FA) vascular exposures and lower extremity FAS on fresh cadavers by 40 PGY-2 to PGY-6 residents was video-recorded from head-mounted cameras. Two colocated trained evaluators assessed IPS before and after training. One surgeon in each pretraining tertile of IPS for each procedure was randomly identified for blind video review. The same 12 surgeons were video-recorded repeating the procedures less than 4 weeks after training. Five evaluators independently reviewed all 96 randomly arranged deidentified videos. Inter-rater reliability/consistency, intraclass correlation coefficients were compared by colocated versus video review of IPS, and errors. Study methodology and bias were judged by Medical Education Research Study Quality Instrument and the Quality Assessment of Diagnostic Accuracy Studies criteria. There were no differences (p ≥ 0.5) in IPS for AA, FA, FAS, whether evaluators were colocated or reviewed video recordings. Evaluator consistency was 0.29 (BA) - 0.77 (FA). Video and colocated evaluators were in total agreement (p = 1.0) for error recognition. Intraclass correlation coefficient was 0.73 to 0.92, dependent on procedure. Correlations video versus colocated evaluations were 0.5 to 0.9. Except for BA, blinded video evaluators discriminated (p competency. Prognostic study, level II.

    The aim of this pilot trial was to study the feasibility of sentinel node percutaneous preoperative gamma probe-guided biopsy as a valid preoperative method of assessment of nodal status compared to surgical sentinel lymph node biopsy. This prospective study enrolled 10 consecutive patients without evidence of axillary lymph node metastases at preoperative imaging. All patients underwent sentinel node occult lesion localization (SNOLL) using radiotracer intradermic injection that detected a "hot spot" corresponding to the sentinel node in all cases. Gamma probe over the skin detection with subsequent ultrasonographically guided needle biopsy of the sentinel node were performed. The percutaneous needle core histopathological diagnosis was compared to the results of the surgical biopsy. Preoperative sentinel node identification was successful in all patients. The combination of preoperative gamma probe sentinel node detection and ultrasound-guided biopsy could represent a valid alternative to intraoperative sentinel node biopsy in clinically and ultrasonographically negative axillary nodes, resulting in shorter duration of surgery and lower intraoperative risks.

    Full Text Available Background: Paediatric patients often present with different painful conditions that require immediate surgical interventions. Despite a plethora of articles on the ketamine-propofol combination, comprehensive evidence regarding the suitable sedoanalgesia regime is lacking due to heterogeneity in study designs. Methods: This prospective, randomized, double-blind, active-controlled trial was conducted in 100 children, of age 3-14 years, American Society of Anesthesiologist physical status IE-IIE, posted for emergency short surgical procedures. Patients were randomly allocated to receive either 2 mL of normal saline (pre-induction plus calculated volume of drug from the 11 mL of ketamine-propofol solution for induction (group PK, n=50 or fentanyl 1.5 μg/kg diluted to 2 mL with normal saline (pre-induction plus calculated volume of drug from the 11 mL of propofol solution for induction (group PF, n=50. In both the groups, the initial bolus propofol 1 mg/kg i.v. (assuming the syringes contained only propofol, for simplicity was followed by adjusted infusion to achieve a Ramsay Sedation Scale score of six. Mean arterial pressure (MAP was the primary outcome measurement. Results: Data from 48 patients in group PK and 44 patients in group PF were available for analysis. Hypotension was found in seven patients (14.6% in group PK compared with 17 (38.6% patients in group PF (P=0.009. Intraoperative MAP was significantly lower in group PF than group PK when compared with baseline. Conclusion: The combination of low-dose ketamine and propofol is more effective and a safer sedoanalgesia regimen than the propofol-fentanyl combination in paediatric emergency short surgical procedures in terms of haemodynamic stability and lesser incidence of apnoea.

    To develop a near-real-time data warehouse (DW) in an academic ophthalmologic center to gain scientific use of increasing digital data from electronic medical records (EMR) and diagnostic devices. Database development. Specific macular clinic user interfaces within the institutional hospital information system were created. Orders for imaging modalities were sent by an EMR-linked picture-archiving and communications system to the respective devices. All data of 325 767 patients since 2002 were gathered in a DW running on an SQL database. A data discovery tool was developed. An exemplary search for patients with age-related macular degeneration, performed cataract surgery, and at least 10 intravitreal (excluding bevacizumab) injections was conducted. Data related to those patients (3 142 204 diagnoses [including diagnoses from other fields of medicine], 720 721 procedures [eg, surgery], and 45 416 intravitreal injections) were stored, including 81 274 optical coherence tomography measurements. A web-based browsing tool was successfully developed for data visualization and filtering data by several linked criteria, for example, minimum number of intravitreal injections of a specific drug and visual acuity interval. The exemplary search identified 450 patients with 516 eyes meeting all criteria. A DW was successfully implemented in an ophthalmologic academic environment to support and facilitate research by using increasing EMR and measurement data. The identification of eligible patients for studies was simplified. In future, software for decision support can be developed based on the DW and its structured data. The improved classification of diseases and semiautomatic validation of data via machine learning are warranted. Copyright © 2017 Elsevier Inc. All rights reserved.

    It is mandatory to incorporate clinical photography in an ophthalmic practice. Patient photographs are routinely used in teaching, presentations, documenting surgical outcomes and marketing. Standardized clinical photographs are part of an armamentarium for any ophthalmologist interested in enhancing his or her practice. Unfortunately, many clinicians still avoid taking patient photographs for want of basic knowledge or inclination. The ubiquitous presence of the digital camera and digital technology has made it extremely easy and affordable to take high-quality images. It is not compulsory to employ a professional photographer or invest in expensive equipment any longer for this purpose. Any ophthalmologist should be able to take clinical photographs in his/her office settings with minimal technical skill. The purpose of this article is to provide an ophthalmic surgeon with guidelines to achieve standardized photographic views for specific procedures, to achieve consistency, to help in pre-operative planning and to produce accurate pre-operative and post-operative comparisons, which will aid in self-improvement, patient education, medicolegal documentation and publications. This review also discusses editing, storage, patient consent, medicolegal issues and importance of maintenance of patient confidentiality. PMID:22446907

    We present 2 cases of a 3-month-old girl and boy who were diagnosed with an infected pseudoaneurysm 2 months after undergoing left-sided modified Blalock-Taussig shunt (mBTS) operations for pulmonary atresia. Because the shunts in both cases were nearly obstructed, they underwent a 2-stage surgical approach: classic BTS operations through a right thoracotomy to establish sufficient pulmonary flow and infected graft removal through a median sternotomy after close observation of the state of the aneurysms. By utilizing autologous tissue from a different thoracic entry, both patients were successfully managed and recovered without any recurrence of infection.
