    Japanese thoracic surgeons have created personal relationship with European and North American surgeons. During the last 10 years, official relation between Japanese Association for Chest Surgery(JACS) and European Society of Thoracic Surgeons (ESTS) has been established besides personal interaction, and communication among the thoracic surgeons in Asia was prompted through Asia Thoracoscopic Surgery Education Program( ATEP). International relationship through academic associations is expected to contribute to encouraging general thoracic surgeons.

    Chronic venous insufficiency is a highly prevalent condition, with significant health and economic repercussions. Although important therapeutic developments have been introduced in recent years, the majority are dealt with by general surgeons in national health hospitals. These surgeons do not have the required and continuous training, and continue to perform classic surgery techniques. Also, their presence at scientific, organisational meetings and training is almost nil. We present an update on developments in phlebology, and tapping into the preliminary results of a national survey, we reflect on the current status of phlebology and beyond for those general surgeons who should have a role in this field.

    Since its inception in 1977, the Canadian Association of General Surgeons (CAGS) has struggled with its responsibility to represent general surgeons in practices across this country. The CAGS has tended to be mute in the presentation of many of its accomplishments, which have improved the role of specialists in community practice, training programs and the subspecialties of general surgery. With the forthcoming changes in direction for the Royal College of Physicians and Surgeons of Canada, based on a recent external survey, the CAGS has a golden opportunity to advocate for a clear identity, autonomous from the Royal College for the purposes of scientific meetings, continuing professional development, scientific and practice affiliation with other surgical specialty societies, and new developments with corporate sector support for advancements in science technology and education. Advocacy for general surgery must be stressed as the priority for the CAGS into the future.

    With the changing delivery of orthopaedic surgical care, there is a need to define the knowledge and competencies that are expected of an orthopaedist providing general and/or acute orthopaedic care. This article provides a proposal for the knowledge and competencies needed for an orthopaedist to practice general and/or acute care orthopaedic surgery. Using the modified Delphi method, the General Orthopaedic Competency Task Force consisting of stakeholders associated with general orthopaedic practice has proposed the core knowledge and competencies that should be maintained by orthopaedists who practice emergency and general orthopaedic surgery. For relevancy to clinical practice, 2 basic sets of competencies were established. The assessment competencies pertain to the general knowledge needed to evaluate, investigate, and determine an overall management plan. The management competencies are generally procedural in nature and are divided into 2 groups. For the Management 1 group, the orthopaedist should be competent to provide definitive care including assessment, investigation, initial or emergency care, operative or nonoperative care, and follow-up. For the Management 2 group, the orthopaedist should be competent to assess, investigate, and commence timely non-emergency or emergency care and then either transfer the patient to the appropriate subspecialist's care or provide definitive care based on the urgency of care, exceptional practice circumstance, or individual's higher training. This may include some higher-level procedures usually performed by a subspecialist, but are consistent with one's practice based on experience, practice environment, and/or specialty interest. These competencies are the first step in defining the practice of general orthopaedic surgery including acute orthopaedic care. Further validation and discussion among educators, general orthopaedic surgeons, and subspecialists will ensure that these are relevant to clinical practice. These

    variation with respect to cost per case and cost of individual items used during isolated rotator cuff repair. Suture anchors represent the most expensive and variable surgeon-directed cost. The wide cost variation seen in all cost categories illustrates both the effect of surgeon choice in procedure cost and the opportunity for significant cost savings in cases of isolated rotator cuff repair. Engaging surgeons in discussion on cost can positively influence the value of care provided to patients if costs can be reduced without affecting the quality of patient outcomes.

    Effective teaching for general surgery residents requires that faculty members with colorectal expertise actively engage in the education process and fully understand the current context for residency training. In this article, we review important national developments with respect to graduate medical education that impact resident supervision, curriculum implementation, resident assessment, and program evaluation. We argue that establishing a culture of respect and professionalism in today's teaching environment is one of the most important legacies that surgical educators can leave for the coming generation. Faculty role modeling and the process of socializing residents is highlighted. We review the American College of Surgeons' Code of Professional Conduct, summarize some of the current strategies for teaching and assessing professionalism, and reflect on principles of motivation that apply to resident training both for the trainee and the trainer.

  11. Ureteral inguinal hernia: an uncommon trap for general surgeons

    2017-01-01

    Inguinal hernias involving the ureter, a retroperitoneal structure, is an uncommon phenomenon. It can occur with or without obstructive uropathy, the latter posing a trap for the unassuming general surgeon performing a routine inguinal hernia repair. Ureteral inguinal hernia should be included as a differential when a clinical inguinal hernia is diagnosed concurrently with unexplained hydronephrosis, renal failure or urinary tract infection particularly in a male. The present case describes a patient with a known ureteroinguinal hernia who proceeded to having a planned hernia repair and ureteric protection. The case is a reminder that when faced with an unexpected finding such an indirect sliding inguinal hernia, extreme care should be taken to ensure that no structures are inadvertently damaged and that a rare possibility is the entrapment of the ureter in the inguinal canal.

  13. Preventing infection in general surgery: improvements through education of surgeons by surgeons.

    LENUS (Irish Health Repository)

    McHugh, S M

    2011-08-01

    Surgical patients are at particular risk of healthcare-associated infection (HCAI) due to the presence of a surgical site leading to surgical site infection (SSI), and because of the need for intravascular access resulting in catheter-related bloodstream infection (CRBSI). A two-year initiative commenced with an initial audit of surgical practice; this was used to inform the development of a targeted educational initiative by surgeons specifically for surgical trainees. Parameters assessed during the initial audit and a further audit after the educational initiative were related to intra- and postoperative aspects of the prevention of SSIs, as well as care of peripheral venous catheters (PVCs) in surgical patients. The proportion of prophylactic antibiotics administered prior to incision across 360 operations increased from 30.0% to 59.1% (P<0.001). Surgical site dressings were observed in 234 patients, and a significant decrease was found in the percentage of dressings that were tampered with during the initial 48h after surgery (16.5% vs 6.2%, P=0.030). In total, 574 PVCs were assessed over the two-year period. Improvements were found in the proportion of unnecessary PVCs in situ (37.9% vs 24.4%, P<0.001), PVCs in situ for >72h (10.6% vs 3.1%, P<0.001) and PVCs covered with clean and intact dressings (87.3% vs 97.6%, P<0.001). Significant improvements in surgical practice were established for the prevention of SSI and CRBSI through a focused educational programme developed by and for surgeons. Potentially, other specific measures may also be warranted to achieve further improvements in infection prevention in surgical practice.

  15. Emergent management of postpartum hemorrhage for the general and acute care surgeon

    Directory of Open Access Journals (Sweden)

    Blankenship Charles L

    2009-11-01

    Full Text Available Abstract Background Postpartum hemorrhage is one of the rare occasions when a general or acute care surgeon may be emergently called to labor and delivery, a situation in which time is limited and the stakes high. Unfortunately, there is generally a paucity of exposure and information available to surgeons regarding this topic: obstetric training is rarely found in contemporary surgical residency curricula and is omitted nearly completely from general and acute care surgery literature and continuing medical education. Methods The purpose of this manuscript is to serve as a topic specific review for surgeons and to present a surgeon oriented management algorithm. Medline and Ovid databases were utilized in a comprehensive literature review regarding the management of postpartum hemorrhage and a management algorithm for surgeons developed based upon a collaborative panel of general, acute care, trauma and obstetrical surgeons' review of the literature and expert opinion. Results A stepwise approach for surgeons of the medical and surgical interventions utilized to manage and treat postpartum hemorrhage is presented and organized into a basic algorithm. Conclusion The manuscript should promote and facilitate a more educated, systematic and effective surgeon response and participation in the management of postpartum hemorrhage.

  16. Learning styles of medical students, general surgery residents, and general surgeons: implications for surgical education

    2010-01-01

    Background Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. Methods The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. Results A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p < 0.03) from the converging learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. Conclusions We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents. PMID:20591159

    Full Text Available Abstract Background There appear to be geographical differences in decisions to perform mastectomy or breast conserving surgery for early-stage breast cancer. This study was carried out to evaluate general surgeons' preferences in breast cancer surgery and to assess the factors predicting cancer practice in Iran. Methods A structured questionnaire was mailed to 235 general surgeons chosen from the address list of the Iranian Medical Council. The questionnaire elicited information about the general surgeons' characteristics and about their work experience, posts they have held, number of breast cancer operations performed per year, preferences for mastectomy or breast conserving surgery, and the reasons for these preferences. Results In all, 83 surgeons returned the completed questionnaire. The results indicated that only 19% of the surgeons routinely performed breast conserving surgery (BCS and this was significantly associated with their breast cancer case load (P Conclusion The findings indicate that Iranian surgeons do not routinely perform BCS as the first and the best treatment modality. Further research is recommended to evaluate patients' outcomes after BCS treatment in Iran, with regard to available radiotherapy facilities and cultural factors (patients' compliance.

  2. General versus vascular surgeon: impact of a vascular fellowship on clinical practice, surgical case load, and lifestyle.

    2010-02-01

    An applicant shortage for vascular surgery (VS) residencies exists despite an increase in available training positions created to meet the growing demands for vascular surgeons. After 3 years of practice as an American Board of Surgery (ABS)-certified/board-eligible general surgeon, the author of this study attended an accredited 1-year VS training fellowship and received an ABS certificate of Added Qualifications in VS. The purpose of this review was to investigate the implications completing a vascular fellowship has had on VS procedure patterns, vascular procedure competency, clinical practice, career, and lifestyle with the aim of attracting trainees to the field of VS. The author's operative logs were reviewed retrospectively to summarize vascular procedures performed before and after the vascular fellowship. Statistical analysis was performed comparing the types and volume of vascular procedures before and after the vascular fellowship. Changes in professional career and personal life also were examined. The author performed 401 vascular procedures during 2.8 years as a general surgeon. In the first 3.4 years after the vascular fellowship, vascular procedure volume increased to 1563. The mean number of vascular procedures performed per year increased from 143.2 as a general surgeon to 459.7 as a vascular surgeon. The three major differences in vascular procedures occurring after the vascular fellowship were (1) a threefold increase in the number of vascular procedures performed, (2) a shift from major open to venous and endovascular procedures, and (3) an increase in case complexity. Specializing in VS also has resulted in increased career opportunities, more career satisfaction, a direct financial benefit, and more flexibility for lifestyle and family. Because of these positive changes, the author encourages medical students and residents interested in VS to explore the specialty early, seek vascular surgeons to serve as mentors, and enter one of the new VS

    The Abdominal Compartment Syndrome (ACS) is a clinical entity recognized for over a century, but only recently its risk criteria, monitorization and treatment have been defined by the World Society of the Abdominal Compartment Syndrome (WSACS). The general surgeon's involvement is vital since this syndrome is common in surgical patients and because its treatment may culminate in a laparostomy. 250 questionnaires of 17 questions were distributed among general surgeons attending the XXVIII Portuguese Congress of Surgery. The data were analyzed using SPSS® v16. We received 36,4% (91) of the delivered questionnaires, most of which from male surgeons (63,7%), from central hospitals (75,8%), working 42 h per week (70.3%), whose average of age was 38 years. About half of the respondents received training in Intensive Care Units. All surgeons had already heard about measuring the Intra- abdominal Pressure (IAP), which was being performed at 89% of their hospitals. About 40% of surgeons only admitted intra-abdominal hypertension above 20 mmHg (only 22% indicated the correct value of 12 mmHg). 36,3% of surgeons suggested that a decompressive laparostomy must be carried out for primary ACS if IAP greater then 20 mmHg with new organ failure; 36.3% favoured the "Vacuum-pack"-like system, and 56% only re-operate the patients "as needed". 48,4% of surgeons had already performed decompressive laparostomy, 66% of which had residence training in a ICU (p = 0,005). Respondents also pointed an average mortality related to ACS of 81% without laparostomy, and a reduction to 38,5% after performing that procedure. Only 26% of the surgeons were aware of the WSACS consensus definitions and recommendations, of those, 83% had already performed a laparostomy (Pdivulgation.

    1996-10-01

    Information retrieval has progressed from a reliance on traditional print sources to the modern era of computer databases and online networks. Surgeons, many from remote areas not served by professional medical libraries, must develop and maintain skills in information retrieval and management in both electronic and standard formats. One hundred thirty-three New Mexico general surgeons were surveyed to identify their information-seeking patterns in five areas: retrieval purposes, retrieval sources, barriers to access, techniques used, and continuing education needs. Ninety-nine (74.4%) surgeons responded to the survey. Ninety-five percent utilize professional meetings, the medical literature, and physician colleagues as information sources. Only 17% utilize the outreach services of the state's only medical school library. Common retrieval barriers were practice demands (71%), isolation from medical schools (30%), computer illiteracy (28%), and rural environment (25%). Continuing education topics related to information management would be valuable to 61% of the surgeons. Sixty-nine percent believe their current ability to access biomedical information is adequate, despite most frequently accessing their personal libraries for information related to decision-making or patient management. These data suggest that, despite significant information needs, surgeons have not embraced newer forms of information retrieval. It is imperative that surgeons acquire and maintain modern information retrieval skills as a means of remaining up-to-date in their profession. Professional surgical organizations and medical librarians should collaborate on these continuing education ventures.

Minilaparotomies were performed by a nephrologist in a minor surgery room under local anesthesia. Conventional laparotomies were performed by a surgeon in an operating room under general anesthesia.Results: Two nephrologists inserted 157 peritoneal catheters, and seven general surgeons inserted 185 peritoneal catheters. The groups had similar characteristics: the mean age was 55 years, 49.5% were men, and the primary diagnoses were diabetic nephropathy, hypertensive nephropathy, and unknown etiology. The implant was successful for 98.09% of group A and 99.46% of group B. There was no procedure-related mortality.

    This study compared the outcomes of infants who underwent surgery in neonatal intensive care units by pediatric surgeons and by general surgeons. This was a retrospective study of infants who underwent surgery in neonatal intensive care units between 2010 and 2014. A total of 227 patients were included. Of these patients, 116 were operated on by pediatric surgeons (PS) and 111 were operated on by general surgeons (GS). The outcome measures were the overall rate of operative complications, unplanned reoperation, mortality rate, length of stay, operative time, and number of total number of operative procedures. The overall operative complication rate was higher in the GS group compared with the PS group (18.7% vs. 7.0%, p=0.0091). The rate of unplanned reoperations was also higher in the GS group (10.8% vs. 3.5%, p=0.0331). The median operation time (90min vs. 75min, p=0.0474) and median length of stay (24days vs. 18days, p=0.0075) were significantly longer in the GS group. The adjusted odd ratios of postoperative complications for GS were 2.9 times higher than that of PS (OR 2.90, p=0.0352). The operative quality and patient outcomes of the PS group were superior to those of the GS group. III. Copyright © 2017 Elsevier Inc. All rights reserved.

  11. Does general surgery residency prepare surgeons for community practice in British Columbia?

    Hwang, Hamish

    2009-06-01

    Preparing surgeons for clinical practice is a challenging task for postgraduate training programs across Canada. The purpose of this study was to examine whether a single surgeon entering practice was adequately prepared by comparing the type and volume of surgical procedures experienced in the last 3 years of training with that in the first year of clinical practice. During the last 3 years of general surgery training, I logged all procedures. In practice, the Medical Services Plan (MSP) of British Columbia tracks all procedures. Using MSP remittance reports, I compiled the procedures performed in my first year of practice. I totaled the number of procedures and broke them down into categories (general, colorectal, laparoscopic, endoscopic, hepatobiliary, oncologic, pediatric, thoracic, vascular and other). I then compared residency training with community practice. I logged a total of 1170 procedures in the last 3 years of residency. Of these, 452 were performed during community rotations. The procedures during residency could be broken down as follows: 392 general, 18 colorectal, 242 laparoscopic, 103 endoscopic, 85 hepatobiliary, 142 oncologic, 1 pediatric, 78 thoracic, 92 vascular and 17 other. I performed a total of 1440 procedures in the first year of practice. In practice the break down was 398 general, 15 colorectal, 101 laparoscopic, 654 endoscopic, 2 hepatobiliary, 77 oncologic, 10 pediatric, 0 thoracic, 70 vascular and 113 other. On the whole, residency provided excellent preparation for clinical practice based on my experience. Areas of potential improvement included endoscopy, pediatric surgery and "other," which comprised mostly hand surgery.

    The Charcot foot (CF) consists of a progressive deterioration of the bones and joints, most common in diabetic patients with advanced neuropathy. The great problem is that can be confused with other processes, delaying the diagnosis and specific treatment. The aim is to analyze the cases of CF diagnosed in our hospital and especially to highlight the role of the general surgeon. Retrospective study of all registered cases diagnosed of CF between the diabetic population of our Department of Health. A review of the literature was performed. From 2008 to 2012, there 7 cases of CF were diagnosed (prevalence 1:710). Two of the patients were diagnosed erroneously of cellulitis. The average time of delay in the diagnosis was 10 weeks (minimum 1, maximum 24). The initial treatment was immobilization of the extremity. Once the edema was eliminated, an offload orthesis was placed according to Sanders's anatomical classification. Evolution was favorable in 5 patients, 1 patient needed amputation, and other one died of acute cardiac pathology. The CF is a more frequent pathology than we believe. The general surgeon is the fundamental prop in the diagnosis and initial treatment. Before the presence of inflammation and edema of the foot in a patient with diabetes and severe neuropathy, once cellulitis, osteomyelitis, and TVP are ruled out, Charcot neuroarthropathy should be considered.

    Joseph Lovell, trained in medicine at Harvard and in military medicine/surgery by the War of 1812, became the first Surgeon General to sit on the reorganised army staff at the tender age of 29 in 1818. With a keen intellect, medical acumen, and wartime experiences for his tools and a close supporting relationship with Commanding General Jacob Jennings Brown and Secretary of War John C Calhoun (1728-1850), Lovell constructed an efficient and effective organisational and administrative framework for the new Medical Department of the US Army. Moreover, he not only redefined the role of the American military physician but also established the professional dignity, respectability and value of the medical officer among line officers and staff. Lovell's 18-year tenure came to an abrupt end, but the operational framework he created became both foundation and legacy for his successors.

    Background Preparing surgeons for clinical practice is a challenging task for postgraduate training programs across Canada. The purpose of this study was to examine whether a single surgeon entering practice was adequately prepared by comparing the type and volume of surgical procedures experienced in the last 3 years of training with that in the first year of clinical practice. Methods During the last 3 years of general surgery training, I logged all procedures. In practice, the Medical Services Plan (MSP) of British Columbia tracks all procedures. Using MSP remittance reports, I compiled the procedures performed in my first year of practice. I totaled the number of procedures and broke them down into categories (general, colorectal, laparoscopic, endoscopic, hepatobiliary, oncologic, pediatric, thoracic, vascular and other). I then compared residency training with community practice. Results I logged a total of 1170 procedures in the last 3 years of residency. Of these, 452 were performed during community rotations.

    2016-07-18

    Minimally invasive direct thoracic interbody fusion (MIS-DTIF) is a new single surgeon procedure for fusion of the thoracic vertebrae below the scapula (T6/7) to the thoracolumbar junction. In this proof of concept study, we describe the surgical technique for MIS-DTIF and report our experience and the perioperative outcomes of the first four patients who underwent this procedure. In this study we attempt to establish the safety and efficacy of MIS-DTIF. We have performed MIS-DTIF on six spinal levels in four patients with degenerative disk disease or disk herniation. We recorded surgery time, blood loss, fluoroscopy time, complications, and patient-reported pain. Throughout the MIS-DTIF procedure, the surgeon is aided by biplanar fluoroscopic imaging and electrophysiological monitoring. The surgeon approaches the spine with a series of gentle tissue dilations and inserts a working tube that establishes a direct connection from the outside of the skin to the disk space. Through this working tube, the surgeon performs a discectomy and inserts an interbody graft or cage. The procedure is completed with minimally invasive (MI) posterior pedicle screw fixation. For the single level patients the mean blood loss was 90 ml, surgery time 43 minutes, fluoroscopy time 293 seconds, and hospital stay two days. For the two-level surgeries, the mean blood loss was 27 ml, surgery time 61 minutes, fluoroscopy time 321 seconds, and hospital stay three days. We did not encounter any clinically significant complications. Thirty days post-surgery, the patients reported a statistically significant reduction of 5.3 points on a 10-point sliding pain scale. MIS-DTIF with pedicle screw fixation is a safe and clinically effective procedure for fusions of the thoracic spine. The procedure is technically straightforward and overcomes many of the limitations of the current minimally invasive (MI) approaches to the thoracic spine. MIS-DTIF has the potential to improve patient outcomes and

    To understand what influences career satisfaction among general surgeons in urban and rural areas in Canada in order to improve recruitment and retention in general surgery. Semistructured interviews were conducted with 32 general surgeons in 2010 who were members of the Canadian Association of General Surgeons and who currently practice in either an urban or rural area. Interviews explored factors contributing to career satisfaction, as well as suggestions for preventive, screening, or management strategies to support general surgery practice. Findings revealed that both urban and rural general surgeons experienced the most satisfaction from their ability to resolve patient problems quickly and effectively, enhancing their sense of the meaningfulness of their clinical practice. The supportive relationships with colleagues, trainees, and patients was also cited as a key source of career satisfaction. Conversely, insufficient access to resources and a perceived disconnect between hospital administration and clinical practice priorities were raised as key "systems-level" problems. As a result, many participants felt alienated from their work by these systems-level barriers that were perceived to hinder the provision of high-quality patient care. Career satisfaction among both urban and rural general surgeons was influenced positively by the social aspects of their work, such as patient and colleague relationships, as well as a perception of an increasing amount of control and autonomy over their professional commitments. The modern general surgeon values a balance between professional obligations and personal time that may be difficult to achieve given the current system constraints.

    Appendectomy is the most common urgent procedure in children, and surgical outcomes may be affected by the surgeon's experience. This study's aim is to compare appendectomy outcomes performed by pediatric surgeons (PSs) and general surgery residents (GSRs). A retrospective review of all patients younger than 16y treated for appendicitis at two different campuses of the same institution during the years 2008-2009 was performed. Appendectomies were performed by PS in one campus and GSR in the other. Primary end points included postoperative morbidity and hospital length of stay. During the study period, 246 (61%) patients were operated by senior GSR (postgraduate year 5-7) versus 157 (39%) patients by PS. There was no significant difference in patients' characteristics at presentation to the emergency room and the rate of appendeceal perforation (11% versus 15%, P=0.32), and noninfectious appendicitis (5% versus 5% P=0.78) also was similar. Laparoscopic surgery was performed more commonly by GSR (16% versus 9%, P=0.02) with shorter operating time (54±1.5 versus 60±2.1, P=0.01). Interestingly, the emergency room to operating room time was shorter for GSR group (419±14 versus 529±24min, P<0.001). The hospital length of stay was shorter for the GSR group (4.0±0.2 versus 4.5±0.2, P=0.03), and broad-spectrum antibiotics were used less commonly (20% versus 53%, P<0.0001) and so was home antibiotics continuation (13% versus 30%, P<0.0001). Nevertheless, postoperative complication rate was similar (5% versus 7%, P=0.29) and so was the rate of readmissions (2% versus 5%, P=0.52). The results of this study suggest that the presence of a PS does not affect the outcomes of appendectomies. Copyright © 2013 Elsevier Inc. All rights reserved.

    The number of polytrauma patient with associated brain injury or commonly referred as 'head injury' has increased tremendously in recent times courtesy to road traffic accident or other causes. This prospective observational study was conducted in patients of head injury admitted through emergency in the department of general surgery in NRS Medical College, Kolkata during the year 2011 to determine the pattern of head injury patients admitted and nature of intervention. A total number of 3861 patients were admitted in a single year. Obviously this represents the tip of the iceburg. Traumatic brain injury was the highest in the age group of 31-40 years (33.5%) followed by 21-30 years (29.1%) in the most fruitful phase of life. The traumatic brain injury death was more common in males. The maximum number of cases was from rural areas ie, farmers and labours. To minimise the morbidity and mortality resulting from head injury there is need for better maintenance of roads, improvement of road visibility and lighting, rigid enforcement of traffic rules and imparting road safety education to school children. Despite valiant efforts and advancement in medical sciences and infrastructure in the form of neurosurgery departments and trauma care units to cope with the changing world of trauma, there still remains a huge responsibility and a definite part to be played by the general surgeons to manage head injury patient even in tertiary hospitals.

    The question of whether cigarette smoking was associated with lung cancer was central to the expansion of epidemiology into the study of chronic diseases in the 1950s. The culmination of this era was the 1964 report of the Advisory Committee to the Surgeon General, a landmark document that included an objective synthesis of the evidence of the health consequences of smoking according to causal criteria. The report concluded that cigarette smoking was a cause of lung cancer in men and sufficient in scope that "remedial action" was warranted at the societal level. The 2014 Surgeon General's report commemorates the 50th anniversary of the 1964 report. The evidence on the health consequences of smoking has been updated many times in Surgeon General's reports since 1964. These have summarized our increasingly greater understanding of the broad spectrum of the deleterious health effects of exposure to tobacco smoke across most major organ systems. In turn, this evidence has been translated into tobacco control strategies implemented to protect the public's health. The Surgeon General report process is an enduring example of evidence-based public health in practice. Substantial progress has been made, but cigarette smoking remains one of the most pressing global health issues of our time.

    The primary aim of this study was to establish concordance of general surgeon's prescribing practice with local IV-oral antibiotic guidelines. The secondary aim was to evaluate the effect of introducing educational antibiotic measures. The Rogers Diffusion of Innovation Model was used to explore the adoption of antibiotic stewardship practices. In this prospective, cohort study, data was collected on 100 pre and 100 post awareness intervention programme patients. The educational intervention comprised raising awareness of a) the guidelines b) pre-intervention results c) introducing an IV-oral antibiotic prompt sheet. The concordance with local guidelines was compared between pre- and post-intervention groups using Fisher's Exact Test or Pearson's Chi Test (SPSS Statistics V22). The concordance of general surgical doctors with local IV-oral antibiotic guidelines was poor and did not improve significantly following the awareness intervention programme. There was no uptake of the antibiotic prompt sheet. There was a trend towards increase in the number of patients switched from IV to oral antibiotics at 48-72 h and significant increase (p review IV antibiotics. Antibiotic governance measures failed to inspire even an initial group of innovators to use the antibiotic prompt sheets. It appears educational measures are effective in improving prescribing behavior and intent amongst a group of early adopters, but this fails to reach a critical mass. In order to improve antibiotic governance and embark upon the Rogers Diffusion of Innovation Curve, more must be done to engage general surgical doctors in timely, judicious antibiotic prescribing.

    According to the 2014 Surgeon General's Report, smoking in early pregnancy can cause orofacial clefts. We sought to examine the implications of this causal link for the potential prevention of orofacial clefts in the United States. Using published data on the strength of the association between orofacial clefts and smoking in early pregnancy and the prevalence of smoking at the start of pregnancy, we estimated the attributable fraction for smoking as a cause of orofacial clefts. We then used the prevalence of orofacial clefts in the United States to estimate the number of orofacial clefts that could be prevented in the United States each year by eliminating exposure to smoking during early pregnancy. We also estimated the financial impact of preventing orofacial clefts caused by maternal smoking based on a published estimate of attributable healthcare costs through age 10 for orofacial clefts. The estimated attributable fraction of orofacial clefts caused by smoking in early pregnancy was 6.1% (95% uncertainty interval 4.4%, 7.7%). Complete elimination of smoking in early pregnancy could prevent orofacial clefts in approximately 430 infants per year in the United States, and could save an estimated $40.4 million in discounted healthcare costs through age 10 for each birth cohort. Understanding the magnitude of the preventable burden of orofacial clefts related to maternal smoking could help focus smoking cessation efforts on women who might become pregnant. © 2014 Wiley Periodicals, Inc.

    Every general dental practitioner and oral and maxillofacial surgeon needs a thorough knowledge of the diagnosis and management of medical emergencies. Cardiopulmonary arrest is the most urgent of emergencies and diagnosis must be done as soon as possible. This paper discusses the importance of the International Liaison Committee on Resuscitation which forms the guidelines for cardiopulmonary resuscitation (CPR), highlighting the important changes in the guidelines of CPR from the year 2000 to 2010, the basic sequence of performing CPR and also the role of defibrillation and the use of automated external defibrillators. Finally the five part chain of survival which is of utmost importance to dental health care professionals and oral and maxillofacial surgeons. All dental health care personnel and oral & maxillofacial surgeons should recognize the importance of the changes in the guidelines of CPR, be trained and allowed to use a properly maintained defibrillator, to respond to cardiac arrest victims.

    We surveyed Canadian General Surgeons to examine decision-making in early stage breast cancer. A modified Dillman Method was used for this mail survey of 1443 surgeons. Practice patterns and factors that influence management choices for: preoperative assessment, definition of margin status, surgical techniques and recommendations for re-excision were assessed. The response rate was 51% with 41% treating breast cancer. Most (80%) were community surgeons, with equal distribution of low/medium/high volume and years of practice categories. Approximately 25% of surgeons "sometimes or frequently" performed diagnostic excisional biopsies while 90% report "frequently" or "always" performing preoperative core biopsies. There was marked variation in defining negative and close margins, in the use of intra-operative margin assessment techniques and recommendations for re-excision. Responses revealed significant variation in attitudes and practices. These findings likely reflect an absence of consensus in the literature and potential gaps between best evidence and practice.

    Full Text Available Abstract The reports of US Surgeon General on smoking are considered the authoritative statement on the scientific state of the art in this field. The previous report on nicotine addiction published in 1988 is one of the most cited references in scientific articles on smoking and often the only citation provided for specific statements of facts regarding nicotine addiction. In this commentary we review the chapter on nicotine addiction presented in the recent report of the Surgeon General. We show that the nicotine addiction model presented in this chapter, which closely resembles its 22 years old predecessor, could only be sustained by systematically ignoring all contradictory evidence. As a result, the present SG's chapter on nicotine addiction, which purportedly "documents how nicotine compares with heroin and cocaine in its hold on users and its effects on the brain," is remarkably biased and misleading.

  8. Reducing Tobacco Use. A report of the Surgeon General. Executive Summary.

    Science.gov (United States)

    2000-12-22

    This report of the Surgeon General on smoking and health, Reducing Tobacco Use, appears at a time of considerable upheaval in the arena of tobacco use control and prevention. Legal and legislative efforts to protect children from tobacco initiation and to diminish the prevalence of smoking among adults are in a state of flux, with some important gains and some sobering setbacks. Major changes in the public stance of the tobacco industry have evoked a reevaluation of strategies for controlling and preventing tobacco uptake. Enormous monetary settlements have provided the resources to fuel major new comprehensive antitobacco efforts, but the ultimate cost and benefit of these resources are still to be determined. Into this changing landscape, the report introduces an assessment of information about the value and efficacy of the major approaches that have been used--educational, clinical, regulatory, economic, and comprehensive--to reduce tobacco use. The report evaluates the scientific evidence for each approach, attempts to place the approaches in the larger context of tobacco control, and provides a vision of the trajectory for tobacco use prevention and control based on these available tools. Thus, although our knowledge about tobacco control remains imperfect, we know more than enough to act now. Widespread dissemination of the approaches and methods shown to be effective in each modality and especially in combination would substantially reduce the number of young people who will become addicted to tobacco, increase the success rate of young people and adults trying to quit using tobacco, decrease the level of exposure of nonsmokers to environmental tobacco smoke, reduce the disparities related to tobacco use and its health effects among different population groups, and decrease the future health burden of tobacco-related disease and death in this country. These achievable improvements parallel the health objectives set forth in Healthy People 2010, the national

    There is overlap between general, abdominal and vascular surgery on one hand and plastic surgery on the other hand, e.g., in hernia surgery, in particular, recurrent hernia, reconstruction of the abdominal wall or defect closure after abdominal or vascular surgery. Bariatric operations involve both special fields too. Plastic surgeons sometimes use skin and muscle compartments of the abdominal wall for reconstruction at other regions of the body. This article aims to i) give an overview about functional, anatomic and clinical aspects as well as the potential of surgical interventions in plastic surgery. General/abdominal/vascular surgeons can benefit from this in their surgical planning and competent execution of their own surgical interventions with limited morbidity/lethality and an optimal, in particular, functional as well as aesthetic outcome, ii) support the interdisciplinary work of general/abdominal/vascular and plastic surgery, and iii) provide a better understanding of plastic surgery and its profile of surgical interventions and options.

    Legislation proposed in 2009 to expand GME set institutional primary care and general surgery production eligibility thresholds at 25% at entry into training. The authors measured institutions' production of primary care physicians and general surgeons on completion of first residency versus two to four years after graduation to inform debate and explore residency expansion and physician workforce implications. Production of primary care physicians and general surgeons was assessed by retrospective analysis of the 2009 American Medical Association Masterfile, which includes physicians' training institution, residency specialty, and year of completion for up to six training experiences. The authors measured production rates for each institution based on physicians completing their first residency during 2005-2007 in family or internal medicine, pediatrics, or general surgery. They then reassessed rates to account for those who completed additional training. They compared these rates with proposed expansion eligibility thresholds and current workforce needs. Of 116,004 physicians completing their first residency, 54,245 (46.8%) were in primary care and general surgery. Of 683 training institutions, 586 met the 25% threshold for expansion eligibility. At two to four years out, only 29,963 physicians (25.8%) remained in primary care or general surgery, and 135 institutions lost eligibility. A 35% threshold eliminated 314 institutions collectively training 93,774 residents (80.8%). Residency expansion thresholds that do not account for production at least two to four years after completion of first residency overestimate eligibility. The overall primary care production rate from GME will not sustain the current physician workforce composition. Copyright © by the Association of American medical Colleges.

    Background and Objective: Existence of doctors with high performance is one of the necessary conditions to provide high quality services. There are different motivations, which could affect their performance. Recognizing Factors which effect the performance of doctors as an effective force in health care centers is necessary. The aim of this article was evaluate the effective factors which influence on clinical performance of general surgery of Tehran University of Medical Sciences in 2015. Methods: This is a cross-sectional qualitative-quantitative study. This research conducted in 3 phases-phases I: (use of library studies and databases to collect data), phase II: localization of detected factors in first phase by using the Delphi technique and phase III: prioritizing the affecting factors on performance of doctors by using qualitative interviews. Results: 12 articles were analyzed from 300 abstracts during the evaluation process. The output of assessment identified 23 factors was sent to surgeons and their assistants for obtaining their opinions. Quantitative analysis of the findings showed that “work qualification” (86.1%) and “managers and supervisors style” (50%) have respectively the most and the least impact on the performance of doctors. Finally 18 effective factors were identified and prioritized in the performance of general surgeons. Conclusion: The results showed that motivation and performance is not a single operating parameter and it depends on several factors according to cultural background. Therefore it is necessary to design, implementation and monitoring based on key determinants of effective interventions due to cultural background. PMID:27157161

    The Surgeon General's Report, Oral Health in America, is the first comprehensive assessment of oral, dental, and craniofacial health in the history of our nation. The intent of this first-ever Report is to alert Americans to the full meaning of oral health and its importance to general health and well-being across the lifespan. Moreover, the Report has been released at a time in human history of enormous changes as well as opportunities. The convergence of public health policies, "quality of life" expectations, global informatics, a new century of biotechnology, the completion of the Human Genome Project, changes in the management of health care, and the acknowledgment of enormous health disparities herald a call to action. These profound dynamics particularly affect children and their caregivers and the multitude of social, economic, and health issues associated with special patients and developmental disabilities. This paper will highlight the issues, provide recommendations, and suggest a call to action.

    Full Text Available Evolvement of urology as a separate scientific discipline depends on several factors. Endoscopic diagnostics, radiological diagnostics, and operative techniques in general surgery, had provided an ability to perform more complex and longer operations. Urology had evolved from the great schools of surgery in Germany and France, and their the most important surgeons, who were intersted in urological surgery. The first endoscope was introduced in 1806, and received today’s form in 1879. Application of "X" rays in medicine started in 1895, and it was later applied as a cystography, retrograde pyelography as well as intravenous urography. The most important thing for the operative technique evolution were application of anhestesia, asepsis and new hemostatic devices. During the one century long development, urology had passed the way from completely unknown field, up to the discipline with the best diagnostic preciseness.

    Full Text Available Abstract Background In order to get sickness benefit a sick-listed person need a medical certificate issued by a physician; in Sweden after one week of self-certification. Physicians experience sick-listing tasks as problematic and conflicts may arise when patients regard themselves unable to work due to complaints that are hard to objectively verify for the physician. Most GPs and orthopaedic surgeons (OS deal regularly with sick-listing issues in their daily practice. The aim of this study was to explore perceived problems and coping strategies related to tasks of sickness certification among general practitioners (GP and orthopaedic surgeons (OS. Methods A cross-sectional study about sickness certification in two Swedish counties, with 673 participating GPs and 149 OSs, who answered a comprehensive questionnaire. Frequencies together with crude and adjusted (gender and working years Odds ratios were calculated. Results A majority of the GPs and OSs experienced problems in sickness certification every week. To assess the patient's work ability, to handle situations when they and the patient had different opinions about the need for sickness absence, and to issue prolongation certificates when the previous was issued by another physician were reported as problematic by a majority in both groups. Both GPs and OSs prolonged sickness certifications due to waiting times in health care or at Social Insurance Office (SIO. To handle experienced problems they used different strategies; OSs issued sickness certificates without personal appointment more often than the GPs, who on the other hand reported having contact with SIO more often than the OSs. A higher rate of GPs experienced support from management and had a common strategy for handling sickness certification at the clinic than the OSs. Conclusion Most GPs and OSs handled sickness certification weekly and reported a variety of problems in relation to this task, generally GPs to a higher extent

To improve patient coordination, systematic structures, guidelines, and processes for creating, transferring, and recognizing information are needed to facilitate referral routines. Methods: Prospective observational survey of implementation of electronic medical record (EMR-supported guidelines for surgical treatment. Results: One university clinic, two local hospitals, 31 municipalities, and three EMR vendors participated in the implementation project. Surgical referral guidelines were developed using the Delphi method; 22 surgeons and seven general practitioners (GPs needed 109 hours to reach consensus. Based on consensus guidelines, an electronic referral service supported by a clinical decision support system, fully integrated into the GPs' EMR, was developed. Fifty-five information technology personnel and 563 hours were needed (total cost 67,000 £ to implement a guideline supported system in the EMR for 139 GPs. Economical analyses from a hospital and societal perspective, showed that 504 (range 401–670 and 37 (range 29–49 referred patients, respectively, were needed to provide a cost-effective service. Conclusion: A considerable amount of resources were needed to reach consensus on the surgical referral guidelines. A structured approach by the Delphi method and close collaboration between IT personnel, surgeons and primary care physicians were needed to

    Following an extensive literature search and a consensus conference with subject matter experts the following conclusions can be drawn: 1. Robotic surgery is still at its infancy, and there is a great potential in sophisticated electromechanical systems to perform complex surgical tasks when these systems evolve. 2. To date, in the vast majority of clinical settings, there is little or no advantage in using robotic systems in general surgery in terms of clinical outcome. Dedicated parameters should be addressed, and high quality research should focus on quality of care instead of routine parameters, where a clear advantage is not to be expected. 3. Preliminary data demonstrates that robotic system have a clinical benefit in performing complex procedures in confined spaces, especially in those that are located in unfavorable anatomical locations. 4. There is a severe lack of high quality data on robotic surgery, and there is a great need for rigorously controlled, unbiased clinical trials. These trials should be urged to address the cost-effectiveness issues as well. 5. Specific areas of research should include complex hepatobiliary surgery, surgery for gastric and esophageal cancer, revisional surgery in bariatric and upper GI surgery, surgery for large adrenal masses, and rectal surgery. All these fields show some potential for a true benefit of using current robotic systems. 6. Robotic surgery requires a specific set of skills, and needs to be trained using a dedicated, structured training program that addresses the specific knowledge, safety issues and skills essential to perform this type of surgery safely and with good outcomes. It is the responsibility of the corresponding professional organizations, not the industry, to define the training and credentialing of robotic basic skills and specific procedures. 7. Due to the special economic environment in which robotic surgery is currently employed special care should be taken in the decision making process when

    Histopathology has continued to develop into a complex discipline of laboratory medicine in the last 30 years. Implementation of new techniques such as immunohistochemistry, in situ hybridization, molecular pathology and gene profiling yields a large amount of information which is used not only to establish diagnosis, but also for prediction and prognosis. The basic conditions for precision and correctness of this information which directly influence the choice of therapy and the outcome for the patient, and eventually the health and the life of the patient, are obtaining a suitable specimen and the best laboratory processing. The first step in this procedure is collection of samples, fixation and submission to the pathology laboratory - the pre-analytical phase. Knowledge of the principles of this phase and their implementation in daily practice in surgery is of main importance for the quality and quantity of information obtained. We introduce the basic rules for proper handling of different specimens depending on the use of conventional and "new" histopathology methods.

    There is no significant biography that records the accomplishments of Sir Wilfred Trotter, who was a general surgeon in its pure sense at a time when surgical specialization was in its infancy. Trotter was born in the 1870s in England. Despite being bedridden during his childhood with a musculoskeletal condition he was able to study medicine at London University, and eventually became Professor and Chair of Surgery at the University College Hospital, a position he held until his death in November 1939. He made many contributions to surgical care, particularly in the field of oncology. He attended to many famous people, including King George V and Sigmund Freud and was greatly honoured in his own milieu. He was named honorary surgeon and Sargent Surgeon to the king. In addition, he was a thoughtful individual who addressed problems in human behaviour, contradicting the stereotype of the contemporary surgeon.

    Experimental medicine has evolved tremendously in the last few years. In particular, the introduction of novel techniques, in-vitro models, knock-out/transgenic animals and high-through put analytical methodologies have resulted in a deeper understanding of cellular pathophysiology and diseases. The daily clinical management has benefited by the introduction of biomarkers and targeted therapies. This development has been accompanied by increasing specialisation across all fields of research and medicine. Therefore, clinical-translational research requires a team of competent partners nowadays. The visceral surgeon can contribute significantly to these projects. The present review highlights several aspects of translational research and put chances and potential pitfalls into perspective in context with the work of the visceral surgeon.

    Developmental dysplasia of the hip (DDH) and flatfoot are common pediatric orthopedic disorders, being referred to and managed by both general and pediatric orthopedic surgeons, through various modalities. Our study aimed to evaluate their consensus and perspective disagreements in terms of diagnostic and therapeutic approaches of the mentioned deformities. Forty participants in two groups of general orthopedic surgeons (GOS) (n=20) and pediatric orthopedic surgeons (POS) (n=20), were asked to answer an 8-item questionnaire on DDH and flexible flatfoot. The questions were provided with two- or multiple choices and a single choice was accepted for each one. Chi-square and Fisher's exact tests was performed to compare the responses. For a neonate with limited hip abduction, hip ultrasonography was the agreed-upon approach in both groups (100% POS vs 71% GOS), and for its interpretation 79% of POS relied on their own whereas 73% of GOS relied on radiologist's report (P=0.002). In failure of a 3-week application of the Pavlik harness, ending it and closed reduction (57% POS vs. 41% GOS) followed by surgery quality assessment with CT scan (64% POS vs. 47% GOS) and without the necessity for avascular necrosis evaluation (79% POS vs. 73% GOS) were the choice measures. In case of closed reduction failure, open reduction via medial approach was the favorite next step in both groups (62% POS and 80% GOS). For the patient with flexible flat foot, reassurance was the choice plan of 79% of pediatric orthopedists. Our findings demonstrated significant disagreements among the orthopedic surgeons. This proposes insufficiency of high-level evidence.

    2009-01-01

    From time immemorial mentoring has been the angular stone sustaining the building of medical and surgical education. Good teachers are not necessarily good mentors, and good mentors are not always good teachers. A combination of both is very plausible and should be encouraged. Today, the qualities of a good mentor, in our case the surgeon-mentor, should include respect, time, commitment, trust, determination, encouragement, patience, and opportunity for independence. The mentee would need to respond to similar virtues of trust, encouragement, and respect. The reciprocal consideration of equally divided roles would be clearly desirable. Recognizing the importance of a good mentor and making this role the priority of medical schools would enhance our ability to form better professionals. It would certainly promote professionalism, better patient care, and research.

  6. Direct solution to the minimal generalized pose.

    2015-03-01

    Pose estimation is a relevant problem for imaging systems whose applications range from augmented reality to robotics. In this paper we propose a novel solution for the minimal pose problem, within the framework of generalized camera models and using a planar homography. Within this framework and considering only the geometric elements of the generalized camera models, an imaging system can be modeled by a set of mappings associating image pixels to 3-D straight lines. This mapping is defined in a 3-D world coordinate system. Pose estimation performs the computation of the rigid transformation between the original 3-D world coordinate system and the one in which the camera was calibrated. Using synthetic data, we compare the proposed minimal-based method with the state-of-the-art methods in terms of numerical errors, number of solutions and processing time. From the experiments, we conclude that the proposed method performs better, especially because there is a smaller variation in numerical errors, while results are similar in terms of number of solutions and computation time. To further evaluate the proposed approach we tested our method with real data. One of the relevant contributions of this paper is theoretical. When compared to the state-of-the-art approaches, we propose a completely new parametrization of the problem that can be solved in four simple steps. In addition, our approach does not require any predefined transformation of the dataset, which yields a simpler solution for the problem.

A retrospective analysis of data obtained from different surgical units in a single center in Qatar over a 3-month period in 2012. A total of 101 patients who underwent surgery and followed regimes for surgical prophylaxis as per hospital guidelines were included in the study. Results. The overall use of antibiotic was 89%, whereas the current practice did not match the recommended hospital protocols in 53.5% of cases. Prolonged antibiotics use (59.3% was the commonest reason for nonadherence followed by the use of an alternative antibiotic to that recommended in the protocol (31.5% and no prophylaxis was used in 9.2% of cases. The rate of compliance was significantly higher among clean surgery than clean contaminated group (P=0.03. Forty-four percent of clean and 65% of clean-contaminated procedures showed noncompliance with the recommended surgical antimicrobial prophylaxis hospital guidelines. Conclusion. Lack of adherence to hospital protocols is not uncommon. This finding remains a challenge to encourage clinicians to follow hospital guidelines appropriately and to consistently apply the surgical antibiotic prophylaxis. The role of clinical pharmacist may facilitate this process across all surgical disciplines.

    To compare self-directed interactive video-based instruction (IVBI) with instructor-led teaching in the acquisition of basic surgical skills by House Surgeons at University of Medicine 1, Yangon. A prospective, 1:1 randomized controlled trial was conducted. Participants were randomized into 2 teaching arms: (1) self-directed IVBI or (2) instructor-led teaching. Self-directed IVBI participants were provided with a portable DVD player that could play, fast forward, rewind, and skip through skills modules. Participants in the instructor-led teaching group were taught in small groups by standardized instructors. Pretesting and posttesting of 1-handed knot tie, 2-handed knot tie, vertical mattress suture, and instrument tie was performed using the Objective Structured Assessment of Technical Skills (OSATS). Students randomized to self-directed IVBI completed an exit survey to assess satisfaction. Demographic data were collected of all participants. University of Medicine 1, Yangon, Myanmar. Fifty participants were randomly selected from 78 eligible House Surgeons who were enrolled in their basic surgery rotation. Demographic characteristics and baseline skills were comparable in participants randomized to IVBI and instructor-led teaching. Mean OSATS score increased from pretest to posttest in both groups (p < 0.001). The mean posttest OSATS score of the IVBI group was 0.72 points below that of the instructor-led teaching group (90% CI: -3.8 to 5.2), with the 90% CI falling below the a priori noninferiority margin, satisfying criteria for noninferiority. More than 90% of students marked either "agree" or "strongly agree" to the following statements on the exit survey: further expansion of IVBI into other skills modules and integration of IVBI into training curriculum. IVBI is noninferior to instructor-led teaching of surgical skills based on OSATS scores. House Surgeons highly rated self-directed IVBI. Self-directed IVBI has the potential to significantly reduce the

    Surgeon-industry conflict of interest (COI) has become a source of considerable interest. Professional medical societies, industry, and policy makers have attempted to regulate potential COI without consideration for public opinion. The objective of this study was to report on the opinions of individuals representing the general public regarding surgeon-industry consulting relationships. Web-based survey. Survey was administered using a "spine Web site," and opinions are collected on surgeon-industry consulting and regulation. Associations among responses to similar questions were assessed to ensure validity and subgroup analysis performed for respondent age, sex, education, insurance, employment, and patient status. Six hundred ten of 642 surveys had complete data. The sample population comprised more females and was older and more educated than the American population. About 80% of respondents felt it was ethical and either beneficial or of no influence to the quality of health care if surgeons were consultants for surgical device companies. Most felt disclosure of an industry relationship was important and paying surgeons royalties for devices, other than those they directly implant, would not affect quality of care. Respondents support multidisciplinary surgeon-industry COI regulation and trust doctors and their professional societies to head this effort. Despite the known potential negative impact of surgeon-industry COI on patient care, this study revealed that this does not seem to be reflected in the opinion of the general public. The respondents felt that disclosure is deemed one of the most important means of self-regulation and COI management, which is in agreement with current trends of most spine societies and journals that are increasing the stringency of disclosure policies.

    The widespread robotic surgery in the world highlighted the relevance of the training programs for young urologists and residents. In the last years, urologic societies and some independent robotic surgeons strongly worked to standardize some general and specific training modules. Theoretical and practical sections of robotic training programs have been recently specified. The role of simulators, dry and wet laboratories, bedside assistance, and modular (step-by-step) training at console represent the most relevant elements of robotic surgeon training. Ideally, these didactic tools should be available in modern training centers. The development of structured robotic training programs should be considered as one of the priorities that the urologic community must take into account in the near future.

    The surgeon aims at a direct, complete removal of the pathology. In spite of the modern advancements of imaging facilities and precision instrumentations, unsatisfactory results and recurrences are not uncommon. This paper provides a general review of the four specific areas in surgery that would benefit from Chinese medicine. Extensive searches were made on four surgical areas based on available English language journals, viz. low-back pain, chronic ulcers, renal calculus, and enuresis in children, in the past 10 years. The quoted communications are mainly related to clinical evidences, while a smaller number of crucial laboratory reports are also included. Low-back pain, a most frequent orthopaedic problem, would benefit from acupuncture treatment. Chronic leg ulcers could achieve better results of healing using herbal supplements. Problems of renal stones, besides the conventional methods of removal, could be further supplemented with herbal drinks that aim at prevention of recurrences. Enuresis in children, an untreatable common condition, may respond well to acupuncture. Surgeons should keep an open mind. In case of difficulties, they could seriously consider options of traditional treatment.

    This study examines the analytic validity of a software tool designed to provide individuals with risk assessments for colorectal cancer based on personal health and family history information. The software is compatible with the US Surgeon General's My Family Health Portrait (MFHP). An algorithm for risk assessment was created using accepted colorectal risk assessment guidelines and programmed into a software tool (MFHP). Risk assessments derived from 150 pedigrees using the MFHP tool were compared with "gold standard" risk assessments developed by three expert cancer genetic counselors. Genetic counselor risk assessments showed substantial, but not perfect, agreement. MFHP risk assessments for colorectal cancer yielded a sensitivity for colorectal cancer risk of 81% (95% confidence interval: 54-96%) and specificity of 90% (95% confidence interval: 83-94%), as compared with genetic counselor pedigree review. The positive predictive value for risk for MFHP was 48% (95% confidence interval: 29-68%), whereas the negative predictive value was 98% (95% confidence interval: 93-99%). Agreement between MFHP and genetic counselor pedigree review was moderate (κ = 0.54). The analytic validity of the MFHP colorectal cancer risk assessment software is similar to those of other types of screening tools used in primary care. Future investigations should explore the clinical validity and utility of the software in diverse population groups.Genet Med 17 9, 753-756.

    Despite the significant contribution of surgical spending to health care costs, most surgeons are unaware of their operating room costs. To examine the association between providing surgeons with individualized cost feedback and surgical supply costs in the operating room. The OR Surgical Cost Reduction (OR SCORE) project was a single-health system, multihospital, multidepartmental prospective controlled study in an urban academic setting. Intervention participants were attending surgeons in orthopedic surgery, otolaryngology-head and neck surgery, and neurological surgery (n = 63). Control participants were attending surgeons in cardiothoracic surgery, general surgery, vascular surgery, pediatric surgery, obstetrics/gynecology, ophthalmology, and urology (n = 186). From January 1 to December 31, 2015, each surgeon in the intervention group received standardized monthly scorecards showing the median surgical supply direct cost for each procedure type performed in the prior month compared with the surgeon's baseline (July 1, 2012, to November 30, 2014) and compared with all surgeons at the institution performing the same procedure at baseline. All surgical departments were eligible for a financial incentive if they met a 5% cost reduction goal. The primary outcome was each group's median surgical supply cost per case. Secondary outcome measures included total departmental surgical supply costs, case mix index-adjusted median surgical supply costs, patient outcomes (30-day readmission, 30-day mortality, and discharge status), and surgeon responses to a postintervention study-specific health care value survey. The median surgical supply direct costs per case decreased 6.54% in the intervention group, from $1398 (interquartile range [IQR], $316-$5181) (10 637 cases) in 2014 to $1307 (IQR, $319-$5037) (11 820 cases) in 2015. In contrast, the median surgical supply direct cost increased 7.42% in the control group, from $712 (IQR, $202-$1602) (16 441 cases

    People with negative self-views may fail to generalize appropriately from success experiences (e.g., Wood, Heimpel, Newby-Clark, & Ross, 2005). We drew on theories regarding self-views (Swann, Griffin, Predmore, & Gaines, 1987) and abstraction (Semin & Fiedler, 1991), as well as past linguistic framing work (e.g., Marigold, Holmes, & Ross, 2007, 2010; Salancik, 1974), to create a new technique to encourage people with negative self-views to generalize broadly from a success experience to the self-concept. We call this technique directed abstraction. In Experiment 1, participants with negative self-views who completed a directed abstraction writing task following success feedback regarding a novel laboratory task generalized more from that success, reporting higher ability levels and greater expectations of future success in the relevant domain. In Experiment 2, directed abstraction produced similar results (including more positive self-related affect, e.g., pride) after participants recalled a past public speaking success. In Experiment 3, participants high in fear of public speaking gave two speeches in a context designed to be challenging yet also to elicit successful performances. Directed abstraction helped these participants generalize from their success to beliefs about their abilities, expectations about the future, and confidence as a speaker. In Experiment 4, directed abstraction following success on a verbal task increased persistence in the face of failure on a subsequent verbal task. We discuss implications for understanding how and when people generalize from a success, compare directed abstraction to existing interventions, and suggest practical applications for this influence technique.

    Surgical trainees are facing limited training opportunities since the introduction of the European Working Time Directive. Smartphone sales are increasing and have usurped computer sales for the first time. In this context, smartphones are an important portable reference and educational tool, already in the possession of the majority of surgeons in training. Technology in the palm of our hands has led to a revolution of accessible information for the plastic surgery trainee and surgeon. This article reviews the uses of smartphones and applications for plastic surgeons in education, telemedicine and global health. A comprehensive guide to existing and upcoming learning materials and clinical tools for the plastic surgeon is included. E-books, podcasts, educational videos, guidelines, work-based assessment tools and online logbooks are presented. In the limited resource setting of modern clinical practice, savvy plastic surgeons can select technological tools to democratise access to education and best clinical care.

  3. The surgeon and the child.

    For many reasons pediatric surgeons have been asked to do all general and thoracic procedures in children. The profession has responded by training more, but the core of special cases requiring pediatric surgical expertise has not changed, and there is concern that the many surgeons now in training will not each do enough cases to attain and maintain operative expertise. This presentation examines the psychological, educational, and surgical literature on the development of expertise, especially operative expertise. From this I conclude that individual surgeon volume when gained in deliberate practice with a coach and with effort is essential, and that several technologies hold promise for allowing deliberate practice in simulation environments. I propose that in order to avoid a decline in pediatric surgical operative expertise we must reorganize pediatric surgical training and practice to align with Optimal Resources for Children's Surgery and the evolution of training in general surgery.

    To explore the relationship between in-hospital mortality following adult cardiac surgery and the time since primary clinical qualification for the responsible consultant cardiac surgeon (a proxy for experience). Retrospective analysis of prospectively collected national registry data over a 10-year period using mixed-effects multiple logistic regression modelling. Surgeon experience was defined as the time between the date of surgery and award of primary clinical qualification. UK National Health Service hospitals performing cardiac surgery between January 2003 and December 2012. All patients undergoing coronary artery bypass grafts and/or valve surgery under the care of a consultant cardiac surgeon. All-cause in-hospital mortality. A total of 292,973 operations performed by 273 consultant surgeons (with lengths of service from 11.2 to 42.0 years) were included. Crude mortality increased approximately linearly until 33 years service, before decreasing. After adjusting for case-mix and year of surgery, there remained a statistically significant (p=0.002) association between length of service and in-hospital mortality (odds ratio 1.013; 95% CI 1.005-1.021 for each year of 'experience'). Consultant cardiac surgeons take on increasingly complex surgery as they gain experience. With this progression, the incidence of adverse outcomes is expected to increase, as is demonstrated in this study. After adjusting for case-mix using the EuroSCORE, we observed an increased risk of mortality in patients operated on by longer serving surgeons. This finding may reflect under-adjustment for risk, unmeasured confounding or a real association. Further research into outcomes over the time course of surgeon's careers is required. © The Royal Society of Medicine.

  5. An examination of the advances in science and technology of prevention of tooth decay in young children since the Surgeon General's Report on Oral Health.

    2009-01-01

    This paper addresses a number of areas related to how effectively science and technology have met Healthy People 2010 goals for tooth decay prevention. In every area mentioned, it appears that science and technology are falling short of these goals. Earlier assessments identified water fluoridation as one of the greatest public health accomplishments of the last century. Yet, failure to complete needed clinical and translational research has shortchanged the caries prevention agenda at a critical juncture. Science has firmly established the transmissible nature of tooth decay. However, there is evidence that tooth decay in young children is increasing, although progress has been made in other age groups. Studies of risk assessment have not been translated into improved practice. Antiseptics, chlorhexidine varnish, and polyvinylpyrrolidone iodine (PVI-I) may have value, but definitive trials are needed. Fluorides remain the most effective agents, but are not widely disseminated to the most needy. Fluoride varnish provides a relatively effective topical preventive for very young children, yet definitive trials have not been conducted. Silver diamine fluoride also has potential but requires study in the United States. Data support effectiveness and safety of xylitol, but adoption is not widespread. Dental sealants remain a mainstay of public policy, yet after decades of research, widespread use has not occurred. We conclude that research has established the public health burden of tooth decay, but insufficient research addresses the problems identified in the report Oral Health in America: A Report of the Surgeon General. Transfer of technology from studies to implementation is needed to prevent tooth decay among children. This should involve translational research and implementation of scientific and technological advances into practice.

  6. Deformed diffusion and generalized Laplacian for directed networks

    CERN Document Server

    Fanuel, Michaël

    2015-01-01

    A diffusion equation on a complex network is usually implemented with the help of the combinatorial Laplacian which incorporates information about the network structure. In this paper, a deformed diffusion equation on directed networks, governed by a generalized Laplacian, is introduced within a framework of discrete differential forms, closely related to combinatorial Hodge theory. Edge directions are incorporated with the help of an edge flow $1$-form, whose deforming impact is controlled by a coupling constant. Hence, information about the community structure is encoded in the dominant modes in the long time limit. On the one hand, for a small deformation of the combinatorial Laplacian, the dominant modes of the deformed diffusion allow to uncover community structures which are only encoded in the edge directions. We show that the dynamics distinguishes two categories of nodes, i.e. the nodes with a majority of outgoing links from the nodes with a majority of incoming links. Furthermore, the categorization...

    The relationships between industry and medical professionals are controversial. The purpose of our study was to evaluate surgeons' current opinions regarding the industry-surgery partnership, in addition to self-reported industry ties. After institutional review board approval, a survey was sent via RedCap to 3,782 surgeons across the United States. Univariate and multivariable regression analyses were performed to evaluate the responses. The response rate was 23%. From the 822 responders, 226 (27%) reported at least one current relationship with industry, while 297 (36.1%) had at least one such relationship within the past 3 years. There was no difference between general surgery versus other surgical specialties (P = .5). Among the general surgery subspecialties, respondents in minimally invasive surgery/foregut had greater ties to industry compared to other subspecialties (P = .001). In addition, midcareer surgeons, male sex, and being on a reviewer/editorial board were associated with having industry ties (P industry are important for innovation. Our study showed that relationships between surgeons and industry are common, because more than a quarter of our responders reported at least one current relationship. Industry relations are perceived as necessary for operative innovation. Copyright © 2017 Elsevier Inc. All rights reserved.

    Many burns surgeons avoid excision and direct closure of acute burns owing to concerns over wound dehiscence, scarring and infection. There is no evidence in the literature to support this practice. We present outcomes of a prospective series of 100 patients who underwent excision and direct closure of 138 burns over a 2-year period, along with results from a survey sent to 33 senior burns surgeons to gauge attitudes towards direct closure in burns surgery. 47% of survey respondents never perform direct closure. Dehiscence was cited as the most common concern, followed by hypertrophic scarring (HTS). In our cohort, the superficial dehiscence rate was 12% and the HTS rate was 16%, with no scarring contractures. Patients with healing time greater than 14 days were more likely to develop HTS (p=0.008), as were those with wound dehiscence (p=0.014). Patients undergoing part-grafting in addition to direct closure took significantly longer to heal than those undergoing direct closure alone (p=0.0002), with the donor site or graft delaying healing in the majority. Excision and direct closure of acute burn wounds avoids donor site morbidity and has an acceptable complication rate. It is a safe and effective treatment for full thickness burns in selected cases.

    Financial incentives are the only form of compensation that will motivate surgeons at an academic health sciences center to perform the tasks outlined in the hospital's mission statement. A questionnaire divided into 5 sections: demographics, compensation, time allocation, benefits and incentives, and motivational factors. The Department of Surgery, The Toronto Hospital, Toronto, Ontario. All academic surgeons (N=64) practicing at The Toronto Hospital in July 1997. Of the 64 eligible mailed surveys, there were responses for 59. Of these 59 surgeons, 48 (81%) receive compensation through a fee-for-service method. However, only 32 (54%) of the surgeons prefer the fee-for-service method, while 18 (31%) prefer salary and 9 (15%) prefer an alternative system. On average, these academic surgeons spend 44% of their time teaching or performing research, for which they receive 14% of their total income. Of the motivational factors assessed, financial bonuses are a positive motivational factor for all "surgeon tasks." In addition, task-specific motivational factors were established for research, teaching, and operating, including research facilities, mentorship and prestige, and interesting case types, respectively. Surgeons are not appropriately renumerated for time spent on academic activities, and many would prefer an alternative form of compensation to the fee-for-service method. Knowledge that surgeons are receptive to tasks supporting the hospital's mission statement leads us to conclude that appropriate motivation can shape the activity of academic surgeons. Financial rewards ranked the highest as a motivational factor for all surgeon tasks; however, task-specific motivational factors were identified. Overall, multiple factors, specifically targeted to the individual, will serve to motivate. Thus, compensation packages based on individual preferences and personal motivational factors will be the most successful.

    Full Text Available OBJECTIVE: To investigate and characterize the professional stereotypes associated with general medicine and surgery among Brazilian medical residents. METHODS: A randomized sample of residents of the General Medicine and Surgery Residence Programs were interviewed and their perceptions and views of general and surgical doctors were compared. RESULTS: The general practitioner was characterized by the residents in general to be principally a sensitive and concerned doctor with a close relationship with the patient; (45%; calm, tranquil, and balanced (27%; with intellectual skills (25%; meticulous and attentive to details (23%; slow to resolve problems and make decisions (22%; and working more with probabilities and hypotheses (20%. The surgeon was considered to be practical and objective (40%; quickly resolving problems (35%; technical with manual skills (23%; omnipotent, arrogant, and domineering (23%; anxious, stressed, nervous, and temperamental (23%; and more decided, secure, and courageous (20%. Only the residents of general medicine attributed the surgeon with less knowledge of medicine and only the surgeons attributed gender characteristics to their own specialty. CONCLUSION: There was considerable similarity in the description of a typical general practitioner and surgeon among the residents in general, regardless of the specialty they had chosen. It was interesting to observe that these stereotypes persist despite the transformations in the history of medicine, i.e. the first physicians (especially regarding the valorization of knowledge and the first surgeons, so-called "barber surgeons" in Brazil (associated with less knowledge and the performance of high-risk procedures.OBJETIVOS: Investigar e caracterizar entre residentes brasileiros os estereótipos profissionais associados ao médico clínico e ao cirurgião.

    1999-11-01

    William Cheselden was Great Britain's foremost surgeon/scientist in the first half of the 18th century. Cheselden directly challenged the Company of Barber-Surgeons' exclusive right to control dissection in London by being the first to conduct a regular series of anatomy lectures and demonstrations outside of the Company's Hall. He incorporated his lecture syllabus into a handbook of anatomy, The Anatomy of the Humane Body, which was used by students for nearly 100 years. Cheselden also wrote the text and drew the illustrations for a majestic atlas of comparative osteology, the Osteographia, or the Anatomy of the Bones. Cheselden used his superior knowledge of anatomy to reduce the morbidity and mortality associated with perineal lithotomy, one of the few operations possible in his era. Sagacious and pragmatic, Cheselden recognized that the enlightened practice of surgery beginning to take root in 18th-century London could flourish only under an autonomous body of surgeons. Cheselden used his personal funds and political skills to urge Parliament to pass legislation for the dissolution of the combined Company of Barber-Surgeons and the establishment of separate and distinct Surgeons' and Barbers' Companies. After disjoinder of the two groups on May 2, 1745, Cheselden served as one of the Wardens of the new Company of Surgeons--a predecessor of the Royal College of Surgeons of England. In 1746, Cheselden, who helped design the first Surgeons' Hall, served as the Company's Master.

    Full Text Available Herein is constructed, using General Relativity, the space metric along the Earth’s trajectory in the Galaxy, where the Earth traces outs a complicated spiral in its orbital motion around the Sun and its concomitant motion with the solar system around the centre of the Galaxy. It is deduced herein that this space is inhomogeneous and anisotropic. The observable properties of the space, characterizing its gravitation, rotation, deformation, and curvature, are obtained. The theory predicts that the observable velocity of light is anisotropic, due to the anisotropy and inhomogeneity of space caused by the presence of gravitation and the space rotation, despite the world-invariance of the velocity of light remaining unchanged. It is calculated that two pairs of synchronised clocks should record a different speed of light for light beams travelling towards the Sun and orthogonal to this direction, of about 4×10−4 c (i. e. 120 km/sec, 0.04% of the measured velocity of light c. This effect should have oscillations with a 12-hour period (due to the daily rotation of the Earth and 6 month period (due to the motion of the Earth around the Sun. The best equipment for detecting the effect is that being used by R. T. Cahill (Flinders University, Australia in his current experiments measuring the velocity of light in an RF coaxial-cable equipped with a pair of high precision synchronized Rb atomic clocks.

  1. A chronic generalized bi-directional brain-machine interface

    A bi-directional neural interface (NI) system was designed and prototyped by incorporating a novel neural recording and processing subsystem into a commercial neural stimulator architecture. The NI system prototype leverages the system infrastructure from an existing neurostimulator to ensure reliable operation in a chronic implantation environment. In addition to providing predicate therapy capabilities, the device adds key elements to facilitate chronic research, such as four channels of electrocortigram/local field potential amplification and spectral analysis, a three-axis accelerometer, algorithm processing, event-based data logging, and wireless telemetry for data uploads and algorithm/configuration updates. The custom-integrated micropower sensor and interface circuits facilitate extended operation in a power-limited device. The prototype underwent significant verification testing to ensure reliability, and meets the requirements for a class CF instrument per IEC-60601 protocols. The ability of the device system to process and aid in classifying brain states was preclinically validated using an in vivo non-human primate model for brain control of a computer cursor (i.e. brain-machine interface or BMI). The primate BMI model was chosen for its ability to quantitatively measure signal decoding performance from brain activity that is similar in both amplitude and spectral content to other biomarkers used to detect disease states (e.g. Parkinson's disease). A key goal of this research prototype is to help broaden the clinical scope and acceptance of NI techniques, particularly real-time brain state detection. These techniques have the potential to be generalized beyond motor prosthesis, and are being explored for unmet needs in other neurological conditions such as movement disorders, stroke and epilepsy.

  2. Transplant surgeon formation: vocation, incentives, between old and new surgeon generations.

    Science.gov (United States)

    Iaria, G; Cardillo, A

    2006-05-01

    The training of the transplant surgeon is one of the most difficult paths in medicine. The transplant surgeon must be trained as a general and a vascular surgeon; he has to be skilled and upgraded in transplant surgical technique; he has to decide the suitability of the donor and of the organs as well as the immunosuppressive therapy for each recipient; he must know the intensive care unit, hepatology, and nephrology. The transplant surgeon has to deal with surgical, infectious, and metabolic complications after organ transplantation. Thus, clinical formation of the transplant surgeon is multifactorial and always upgraded. However, transplants never happen in the morning; retrivals are more likely to be in the night (especially the holidays ones). "Weekend" is a word not frequently used by transplant surgeons. Moreover, when the transplant procedure happens, the normal activity of the ward and of the outpatient clinic were have to be done. The transplant surgeon must have a sort of "vocation" for such a job. Organ harvesting setting is a good proof of adaptability, always during nighttime, often in small hospitals with operating room nurses unfamiliar with the procedure, sometimes waiting for some colleagues or delaying the surgery. This vocation is enhanced by enthusiasm, but incentives are necessary to feed this love. Incentives should be professional and economic; transplant surgeons should be allowed to make clinical decisions, to choose the surgical technique of transplantation, to control the decision process. Lastly, due to the "total on call," the surgeon should profit from a right salary avoiding extramural activities.

  3. Leo Doyle, master surgeon.

    Science.gov (United States)

    Vellar, I

    2000-10-01

    On 3 March 1953 Leo Doyle died at the Mercy Hospital, Melbourne. The day before he died Leo Doyle had been operating at the Mercy Hospital when he took ill. Doyle's final illness was almost certainly the result of the severe aortic stenosis that had been developing over some years. His death at the relatively young age of 61 ended the career of a man described by Sir Gordon Gordon Taylor as the greatest technical surgeon that he had ever seen. In all likelihood Australian surgery will never see the likes of Doyle, a virtuoso surgeon, again. And yet to many of the surgeons who were Doyle's contemporaries and to those who followed him he remained somewhat of an enigma. Perhaps in some way the description of the great French surgeon Baron Dupuytren may also be applicable to Leo Doyle: known to all, loved by many, understood by few. By all accounts Leo Doyle's surgical repertoire knew no bounds. He operated with equal facility on the central nervous system, the head and neck, in the thorax, abdomen and pelvis and he was more than competent in gynaecology, urology and orthopaedics. In the latter part of his career he became, par excellence, a cancer surgeon. He was, arguably, Australia's first surgical oncologist. No procedure was deemed too complicated or demanding. Like some other superb technicians his judgement at times did not match his technical ability. Doyle was one of the first surgeons in Australia to perform hindquarter amputation and he helped to pioneer the operations of total gastrectomy and oesophagogastrectomy. An avid reader of the surgical literature, he possessed an enormous library which was matched by an equally large collection of surgical instruments. Unlike Devine he published relatively little. He was not a good clinical teacher, preferring to teach by example in the operating theatre. Although interested in music and the visual arts, surgery was his life.

  11. Direct Modulation of Microtubule Stability Contributes to Anthracene General Anesthesia

    2013-01-01

    Recently, we identified 1-aminoanthracene as a fluorescent general anesthetic. To investigate the mechanism of action, a photoactive analogue, 1-azidoanthracene, was synthesized. Administration of 1-azidoanthracene to albino stage 40–47 tadpoles was found to immobilize animals upon near-UV irradiation of the forebrain region. The immobilization was often reversible, but it was characterized by a longer duration consistent with covalent attachment of the ligand to functionally important targets. IEF/SDS-PAGE examination of irradiated tadpole brain homogenate revealed labeled protein, identified by mass spectrometry as β-tubulin. In vitro assays with aminoanthracene-cross-linked tubulin indicated inhibition of microtubule polymerization, similar to colchicine. Tandem mass spectrometry confirmed anthracene binding near the colchicine site. Stage 40–47 tadpoles were also incubated 1 h with microtubule stabilizing agents, epothilone D or discodermolide, followed by dosing with 1-aminoanthracene. The effective concentration of 1-aminoanthracene required to immobilize the tadpoles was significantly increased in the presence of either microtubule stabilizing agent. Epothilone D similarly mitigated the effects of a clinical neurosteroid general anesthetic, allopregnanolone, believed to occupy the colchicine site in tubulin. We conclude that neuronal microtubules are “on-pathway” targets for anthracene general anesthetics and may also represent functional targets for some neurosteroid general anesthetics. PMID:23484901

    Barriers to successful innovation can be identified and potentially addressed by exploring the perspectives of key stakeholders in the innovation process. Cardiac surgeons in Canada were surveyed for personal perspectives on biomedical innovation. Quantitative data was obtained by questionnaire and qualitative data via interviews with selected survey participants. Surgeons were asked to self-identify into 1 of 3 categories: "innovator," "early adopter," or "late adopter," and data were compared between groups. Most surgeons viewed innovation favourably and this effect was consistent irrespective of perceived level of innovativeness. Key barriers to the innovation pathway were identified: (1) support from colleagues and institutions; (2) Canada's health system; (3) sufficient investment capital; and (4) the culture of innovation within the local environment. Knowledge of the innovation process was perceived differently based on self-reported innovativeness. The majority of surgeons did not perceive themselves as having the necessary knowledge and skills to effectively translate innovative ideas to clinical practice. In general, responses indicate support for implementation of leadership and training programs focusing on the innovation process in an effort to prepare surgeons and enhance their ability to successfully innovate and translate new therapies. The perspectives of cardiac surgeons provide an intriguing portal into the challenges and opportunities for healthcare innovation in Canada. Copyright © 2012 Canadian Cardiovascular Society.

    Ergonomic practice increases the productivity, quality, and longevity of the dermatologic surgeon. When used properly, magnification devices can be ergonomic and beneficial additions to the dermatologic surgeon's practice. Herein, we review the available magnification options for the dermatologic surgeon and evaluate the options based on cost, design, and functional advantages and disadvantages. Magnification for the dermatologic surgeon may be a useful tool for a healthier, more efficient, and higher-quality practice.

    For the last 100 years, General Relativity (GR) has taken over the gravitational theory mantle held by Newtonian Gravity for the previous 200 years. This article reviews the status of GR in terms of its self-consistency, completeness, and the evidence provided by observations, which have allowed GR to remain the champion of gravitational theories against several other classes of competing theories. We pay particular attention to the role of GR and gravity in cosmology, one of the areas in which one gravity dominates and new phenomena and effects challenge the orthodoxy. We also review other areas where there are likely conflicts pointing to the need to replace or revise GR to represent correctly observations and consistent theoretical framework. Observations have long been key both to the theoretical liveliness and viability of GR.We conclude with a discussion of the likely developments over the next 100 years.

    The generalized least squares (LS) problem appears in many application areas. Here W is an m × m symmetric positive definite matrix and A is an m × n matrix with m≥n. Since the problem has many solutions in rank deficient case, some special preconditioned techniques are adapted to obtain the minimum 2-norm solution. A block SOR method and the preconditioned conjugate gradient (PCG) method are proposed here. Convergence and optimal relaxation parameter for the block SOR method are studied. An error bound for the PCG method is given. The comparison of these methods is investigated. Some remarks on the implementation of the methods and the operation cost are given as well.

    Herniations of the cervical disk in plastic surgeons are far more common in practice than the paucity of reported cases would indicate. A likely explanation may be the peculiar, nonergonomic positions that plastic surgeons must hold during surgery while wearing a headlight and loupes. From January 2003 to December 2006, at Tri-Service General Hospital, Taiwan, 4 plastic surgeons experienced herniations of the cervical disk. Magnetic resonance imaging study indicated there was disk herniation or bulging with spinal cord impingement. Two plastic surgeons received cervical diskectomy, corpectomy with strut reconstruction using titanium cages. These 2 surgeons were symptom-free 2 years after their operations. The other 2 plastic surgeons were under conservative physical therapy with persistent symptoms. The clinical evidence indicated that cervical disk herniation is an occupational hazard in plastic surgeons. To prevent prolonged hyperflexion and twisting of the neck, we proposed wearing a cervical brace during surgery for the plastic surgeons at Tri-Service-General Hospital since January 2008. No more plastic surgeons have experienced herniation of the cervical disk since then. The results indicated that wearing a cervical brace may be an effective measure to protect plastic surgeons from cervical disk disease.

    Fernández del Castillo-Sánchez, Carlos

    2012-01-01

    Our vocation has called us to become physicians and we have learned and practiced surgery as part of our medical training and knowledge. Surgery is an art expressed during each intervention carried out with effectiveness and devotion; enjoying the pleasure to perform it without hurry, with harmony, fluency and cleanness. Therefore, medicine and surgery belong to the same vocation being at service of people with the clear mission to heal patients and if we favor it, this activity will get our attention firmly and forever. A physician is a sensitive person that understands the sadness and happiness consequence of his actions at the office, operating room, research and relationships with colleagues. This provides him a pleasant experience of practicing medicine and especially surgery. Medical and surgical professions produce an irresistible attraction and they are very rewarding experiences; however, as time goes by there are effects over physician's health. Surgeons will switch from an active professional role into a passive agent and will need to assess himself and answer if he is still in optimal conditions to practice medicine. Therefore, every surgeon must be prepared to grow old from the start and preserve his Faith once retirement has been accepted as the next step in his career.

    Rounding by trauma surgeons is a complex multidisciplinary team-based process in the inpatient setting. Implementation of lean methodology aims to increase understanding of the value stream and eliminate nonvalue-added (NVA) components. We hypothesized that analysis of trauma rounds with education and intervention would improve surgeon efficacy. Level 1 trauma center with 4300 admissions per year. Average non-intensive care unit census was 55. Five full-time attending trauma surgeons were evaluated. Value-added (VA) and NVA components of rounding were identified. The components of each patient interaction during daily rounds were documented. Summary data were presented to the surgeons. An action plan of improvement was provided at group and individual interventions. Change plans were presented to the multidisciplinary team. Data were recollected 6 mo after intervention. The percent of interactions with NVA components decreased (16.0% to 10.7%, P = 0.0001). There was no change between the two periods in time of evaluation of individual patients (4.0 and 3.5 min, P = 0.43). Overall time to complete rounds did not change. There was a reduction in the number of interactions containing NVA components (odds ratio = 2.5). The trauma surgeons were able to reduce the NVA components of rounds. We did not see a decrease in rounding time or individual patient time. This implies that surgeons were able to reinvest freed time into patient care, or that the NVA components were somehow not increasing process time. Direct intervention for isolated improvements can be effective in the rounding process, and efforts should be focused upon improving the value of time spent rather than reducing time invested.

    The cost and logistics of deploying the American College of Surgeons (ACS)/Association of Program Directors in Surgery (APDS) National Technical Skills Curriculum across all training years are not known. This information is essential for residency programs choosing to adopt similar curricula. A task force evaluated the authors' institution's existing simulation curriculum and enhanced it by implementing the ACS/APDS modules. A 35-module curriculum was administered to 35 general surgery residents across all 5 clinical years. The costs and logistics were noted, and resident satisfaction was assessed. The annual operational cost was $110,300 ($3,150 per resident). Cost per module, per resident was $940 for the cadaveric module compared with $220 and $240 for dry simulation and animal tissue-based modules, respectively. Resident satisfaction improved from 2.45 to 4.78 on a 5-point, Likert-type scale after implementing the ACS/APDS modules. The ACS/APDS skills curriculum was implemented successfully across all clinical years. Cadaveric modules were the most expensive. Animal and dry simulation modules were equivalent in cost. The addition of tissue-based modules was associated with high satisfaction. Copyright © 2014 Elsevier Inc. All rights reserved.

    Burnout is common in professions such as medicine in which employees have frequent and often stressful interpersonal interactions where empathy and emotional control are important. Burnout can lead to decreased effectiveness at work, negative health outcomes, and less job satisfaction. A relationship between burnout and job satisfaction is established for several types of physicians but is less studied among surgeons who treat musculoskeletal conditions. We asked: (1) For surgeons treating musculoskeletal conditions, what risk factors are associated with worse job dissatisfaction? (2) What risk factors are associated with burnout symptoms? Two hundred ten (52% of all active members of the Science of Variation Group [SOVG]) surgeons who treat musculoskeletal conditions (94% orthopaedic surgeons and 6% trauma surgeons; in Europe, general trauma surgeons do most of the fracture surgery) completed the Global Job Satisfaction instrument, Shirom-Malamed Burnout Measure, and provided practice and surgeon characteristics. Most surgeons were male (193 surgeons, 92%) and most were academically employed (186 surgeons, 89%). Factors independently associated with job satisfaction and burnout were identified with multivariable analysis. Greater symptoms of burnout (β, -7.13; standard error [SE], 0.75; 95% CI, -8.60 to -5.66; p < 0.001; adjusted R(2), 0.33) was the only factor independently associated with lower job satisfaction. Having children (β, -0.45; SE, 0.0.21; 95% CI, -0.85 to -0.043; p = 0.030; adjusted R(2), 0.046) was the only factor independently associated with fewer symptoms of burnout. Among an active research group of largely academic surgeons treating musculoskeletal conditions, most are satisfied with their job. Efforts to limit burnout and job satisfaction by optimizing engagement in and deriving meaning from the work are effective in other settings and merit attention among surgeons.

    We as plastic surgeons are engrossed and consumed by our quest to optimize patient care. In so doing, we are often distracted by that aspect of our practice which has direct bearing on patient care yet for which we are the least prepared--the business aspect. The entire population of Canadian plastic surgeons was surveyed in an effort to establish real and perceived needs of this group with respect to the business management of their practices. The survey elicited demographic information, information on business educational background, interest, and current commitment in acquiring business knowledge, and a final category of questions dealing with how well these surgeons function as business managers. Of the 315 plastic surgeons surveyed, 122 (39 percent) responded, which, in and of itself, indicates an interest in this aspect of their practices. Twelve respondents were excluded from the study for various reasons. Eighty of the 110 remaining respondents (72 percent) used a hospital-integrated facility for both emergency and elective outpatient procedures. Eighty-four of the 110 respondents (76 percent) indicated that 10 percent of their hours per week of inpatient booked operating time was canceled. Ninety-three percent of respondents felt that a business course to familiarize surgeons with common business situations and areas of personal finance would be beneficial. Few were previously educated in business, and similarly, few had great ongoing interest in business, although the majority of respondents used publications specifically dealing with financial matters (provided by the Canadian Medical Association). Twenty-three percent of respondents saw themselves in a growing role as businesspeople; 24 percent felt this dual role was enjoyable, while 29 percent felt this role was forced on them. A total of 21 percent of respondents did not see themselves as businesspeople at all. The six basic functions of a manager (planning, acquiring, organizing, actuating

    Conflict of interest (COI) as it applies to medical education and training has become a source of considerable interest, debate, and regulation in the last decade. Companies often pay surgeons as faculty for educational events and often sponsor and give financial support to major professional society meetings. Professional medical societies, industry, and legislators have attempted to regulate potential COI without consideration for public opinion. The practice of evidence-based medicine requires the inclusion of patient opinion along with best available evidence and expert opinion. The primary goal of this study was to assess the opinion of the general population regarding surgeon-industry COI for education-related events. A Web-based survey was administered, with special emphasis on the surgeon's role in industry-sponsored education and support of professional societies. A survey was constructed to sample opinions on reimbursement, disclosure, and funding sources for educational events. There were 501 completed surveys available for analysis. More than 90% of respondents believed that industry funding for surgeons' tuition and travel for either industry-sponsored or professional society educational meetings would either not affect the quality of care delivered or would cause it to improve. Similar results were generated for opinions on surgeons being paid by industry to teach other surgeons. Moreover, the majority of respondents believed it was ethical or had no opinion if surgeons had such a relationship with industry. Respondents were also generally in favor of educational conferences for surgeons regardless of funding source. Disclosures of a surgeon-industry relationship, especially if it involves specific devices that may be used in their surgery, appears to be important to respondents. The vast majority of respondents in this study do not believe that the quality of their care will be diminished due to industry funding of educational events, for surgeon

    Femoral component size selection during total knee arthroplasty should not vary from surgeon to surgeon for patients with the same bone size. This study explored if systematic variations in femoral component size selection exist. Thirteen surgeons' choices of femoral component size (Duracon, n = 1388; Triathlon, n = 740) were analyzed using a generalized linear model with femoral component size as the dependent variable and surgeon identification, years in practice, and adult reconstruction fellowship training as the independent variables. The model adjusted for differences in bone size. It was found that more experienced surgeons implant larger femoral components. New instruments and training protocols may be necessary to adjust for surgeon experience.

    During the war time when Polish borders had not been established yet, apart from having two surgical departments Jagiellonian University, Krakow had surgical departments in the Bonifratow, Izraelicki and Military Hospitals. More surgical departments were opened up in later years in pubic Health System Hospitals, among them were Narutowicz at near Pradnicka street and Sisters of Mercy at Lea street. Other well-known Krakow surgeons operated in smaller, private surgeries, such as: Dom Zdrowia (House of Health) or Zwiazkowy (Union) Clinic. At that time only 30 Surgeons worked in Kraków. They were outstanding specialists with a broad practice. Among them were Maksymilian Rutkowski, Jan Glatzel, Stanislaw Nowicki, Michal Hladij. Gradually, younger surgeons started to join them. they were: Jan Kowalczyk, Jerzy Jasienski, Stanislaw Kania, Wladyslaw Laszczak, Jozef Bugusz, Jozef Gasinski. Many of them who worked in the surgical hospitals in Krakow, left the city after obtaining a professorship (like Kornel Michejda, professor at the University of Wilno) or became heads of wards, like Zygmunt Drobniewicz, Alfons Mackowski and Tadeusz Guschlbauer. All of these surgeons were highly respected by the medical community as well as by the general public in their respective town and surrounding areas. A large income allowed that best of them to fund and supply their own wards. Occasionally, however, among the less successful surgeons, an uncompromising competition for patients developed. These events were disapproved and condemned by the medical establishment. Many surgeons led an active life outside of their profession. A surgeon with an exceptionally colorful personality was Jan Glatzel: witty, highly intelligent, a connoisseur of fine art, book lover with an active social life. Maksymilian Rutkowski was active in charitable organizations, helping to support Bratnia Pomoc Medykow.

    1997-01-01

    This article describes the position of woman surgeons in the Netherlands. In 1913 the first woman, Heleen Robert, was accepted as member of the Dutch Society of Surgery. Three others, Jeanne Knoop, Frieda van Hasselt and Rosalie Wijnberg, followed during the next ten years. The nomination of Rosalie Wijnberg caused a turbulent discussion as she was working as a gynaecologist and not as a surgeon. One can wonder about this argument as other members were gynaecologists too. It seems that the male attitudes towards women were changing as more women entered the male dominated field. Nevertheless, from 1931 on, the year in which the registration of specialists was created, a number of women succeeded in obtaining a registration in surgery. Four of them were interviewed: dr. D.A.E. Norel, A.G. Wiersum-de Kwaadsteniet, J. Leeksma-Lievense and A.A. Fierstra. The general opinion still is that surgery is not a female profession. At the moment there are some twenty women working as general surgeon compared to a seven hundred men.

    Healthcare professionals can be seriously affected when they are involved in major clinical incidents. The impact of such incidents on staff is of particular relevance to surgery, as the operating room is one of the highest-risk areas for serious complications. This qualitative study aimed to assess the personal and professional impact of surgical complications on surgeons. This single time point study involved semistructured, individual interviews with general and vascular surgeons, consultants and senior registrars from two National Health Service organizations in London, UK. Twenty-seven surgeons participated. Many were seriously affected by major surgical complications. Surgeons' practice was also often affected, not always in the best interest of their patients. The surgeons' reactions depended on the preventability of the complications, their personality and experience, patient outcomes and patients' reactions, as well as colleagues' reactions and the culture of the institution. Discussing complications, deconstructing the incidents and rationalizing were the most commonly quoted coping mechanisms. Institutional support was generally described as inadequate, and the participants often reported the existence of strong institutional blame cultures. Suggestions for supporting surgeons in managing the personal impact of complications included better mentoring, teamwork approaches, blame-free opportunities for the discussion of complications, and structures aimed at the human aspects of complications. Those involved in the management of surgical services need to consider how to improve support for surgeons in the aftermath of major surgical incidents. © 2013 British Journal of Surgery Society Ltd.

    This study analyzed the homepages of 250 cosmetic surgeons' websites by focusing on the representation of cosmetic surgery providers, cosmetic surgery recipients, and cosmetic surgery practice itself. Based on a literature review, some common elements of the webpages were preidentified as the indicators of professionalism or commercialism. Subsequently, each homepage was scrutinized for their presence and salience. Overall, cosmetic surgeons' websites were high in professionalism and low in commercialism in their representation of the service providers. In depicting the recipients, the websites were moderate in both professionalism and commercialism. The representation of practice was low in professionalism and moderate in commercialism. Implications of these findings for doctors, regulators, and consumer advocates are discussed and directions for future research are proposed.

Thirty-six of 43 (83.7%) invited surgeons participated in the study. According to their MBI scores, surgeons suffered from low (10, 27.8%), moderate (23, 63.9%), and high (3, 8.3%) levels of burnout. Comparatively, 23 (63.9%) demonstrated moderate burnout according to their ProQOL scores. Substantial psychiatric morbidity was observed in 16 (44.0%) surgeons per their GHQ-12 scores. Consumption of alcohol was noted in 29 (80.6%) surgeons, and 12 (33.4%) had AUDIT scores characterizing their alcohol use in excess of low-risk guidelines or as harmful or hazardous drinking. Surgeons of Fijian nationality showed higher MBI emotional exhaustion and depersonalization scores compared with surgeons of other nationalities. Surgeons with an awareness of the availability of counseling services at their hospitals showed low AUDIT and ProQOL burnout scores. Smokers, alcohol drinkers, and kava drinkers showed higher AUDIT scores. This study highlights a level of occupational stress and burnout among surgeons in Fiji and a lack of awareness of their mental and physical well-being. The authors recommend that occupational stress and burnout intervention strategies be put in place in hospitals in Fiji.

    Statistical regularity in the dynamics of wind direction has been found. The density distribution of the increment of the wind-direction angle has been approximated using a generalized advanced logistic distribution. The advanced logistic distribution involves an additional power-law parameter. The parameters of the approximation function have been computed from experimental data using the method of least squares. The consistency of the proposed function with meteorological data has been tested using Pearson's chisquared test and the Kolmogorov test.

    The surgeon of the new millennium has come a long way from his humble beginnings in the Middle Ages as the lowly barber-surgeon. The skills and techniques developed by outstanding surgeons like Astley Cooper of the 19th century have withstood the test of time and have been refined by subsequent generations of surgical masters. The scientific basis of modern surgery was put on a firm footing in the early 19th century through the discovery of anaesthesia and microorganisms as a cause of many diseases and surgical complications. The 20th century brought about rapid progress in medicine, information technology (IT) and the life sciences, and closed with a big bang with the completion of the sequencing of the human genome. For the surgeon of the 21st century to remain relevant, he must embrace the concept of the Total Surgeon. Not doing so will render him irrelevant in the course of time, for having good surgical technique alone is insufficient. He must also lead in scientific endeavours to push the frontiers of the life sciences in attempts to solve the insoluble, and be scholarly in thought, attitude and behaviour. In other words, he must be a Surgeon-Scientist-Scholar.

    Casualties in military conflict produce patterns of injuries that are not seen in routine surgical practice at home. In an era of increasing surgical sub-specialization the deployed surgeon needs to acquire and maintain a wide range of skills from a variety of surgical specialties. Improvised explosive devices (IEDs) have become the modus operandi for terrorists and in the current global security situation these tactics can be equally employed against civilian targets. Therefore, knowledge and training in the management of these injuries are relevant to both military and civilian surgeons. To create this kind of military surgeon the so-called "DUO-plus" model for the training of surgical officers (specialization general surgery plus a second specialization either in visceral surgery or orthopedics/trauma surgery) has been developed in the Joint Medical Service of the German Bundeswehr. Other relevant skills, such as emergency neurotraumatology, battlefield surgery with integrated oral and craniomaxillofacial surgery and emergency gynecology, are integrated into this concept and will be taught in courses. Log books will be kept in accordance with the training curricula. On successful completion of the program medical officers will be officially appointed as Medical Officer "Einsatzchirurg" by their commanding officers for a maximum of 5 years and it will be necessary to renew it after this period. These refresher programs will require participation in visiting physicians programs in the complementary surgical disciplines in order to retain the essential specific skills.

  10. Plaster of Paris: the orthopaedic surgeon heritage.

    2016-08-01

    Plastering is one of the most ancient of the building handicrafts. Plaster is the common name for calcium sulphate hemi hydrate made by heating the mineral gypsum, the common name for sulphate of lime. In the tenth century the Arabs used liquid plaster in orthopaedic treatment. At the beginning of the nineteenth century, patients with fractures of the lower extremities-and often of the upper extremities as well-were treated in bed with restriction of all activity for many weeks until the fractures united. It was the practice of surgeons to dress wounds and fractures at frequent intervals. The bandages, pads, and splints were removed, the fractures manipulated, and the dressings reapplied. The search for simpler, less cumbersome methods of treatment led to the development of occlusive dressings, stiffened at first with starch and later with plaster of Paris. The ambulatory treatment of fractures was the direct result of these innovations. Two military surgeons, Antonius Mathijsen of the Netherlands, and Nikolai Ivanovitch Pirogov of Russia, were responsible for the introduction of the new plaster bandage technique. At the beginning of the twentieth century the technique was improved by Jean-François Calot, a French surgeon, who invented the hand manufacture of plaster bandage as a roll. During the twentieth century, walking cast and ambulation for fresh fractures were developed with plaster and pin incorporated in plaster; the open fracture care concept was introduced with plaster of Paris by Trueta before the external fixation.

    OBJECTIVE: To determine whether surgical subspecialty training in colorectal surgery or frequency of rectal cancer resection by the surgeon are independent prognostic factors for local recurrence (LR) and survival. SUMMARY BACKGROUND DATA: Variation in patient outcome in rectal cancer has been shown among centers and among individual surgeons. However, the prognostic importance of surgeon-related factors is largely unknown. METHODS: All patients undergoing potentially curative low anterior resection or abdominoperineal resection for primary adenocarcinoma of the rectum between 1983 and 1990 at the five Edmonton general hospitals were reviewed in a historic-prospective study design. Preoperative, intraoperative, pathologic, adjuvant therapy, and outcome variables were obtained. Outcomes of interest included LR and disease-specific survival (DSS). To determine survival rates and to control both confounding and interaction, multivariate analysis was performed using Cox proportional hazards regression. RESULTS: The study included 683 patients involving 52 surgeons, with > 5-year follow-up obtained on 663 (97%) patients. There were five colorectal-trained surgeons who performed 109 (16%) of the operations. Independent of surgeon training, 323 operations (47%) were done by surgeons performing < 21 rectal cancer resections over the study period. Multivariate analysis showed that the risk of LR was increased in patients of both noncolorectal trained surgeons (hazard ratio (HR) = 2.5, p = 0.001) and those of surgeons performing < 21 resections (HR = 1.8, p < 0.001). Stage (p < 0.001), use of adjuvant therapy (p = 0.002), rectal perforation or tumor spill (p < 0.001), and vascular/neural invasion (p = 0.002) also were significant prognostic factors for LR. Similarly, decreased disease-specific survival was found to be independently associated with noncolorectal-trained surgeons (HR = 1.5, p = 0.03) and surgeons performing < 21 resections (HR = 1.4, p = 0.005). Stage (p < 0

    It has become commonplace for patients to access online reviews of physicians when making choices about health care, just as any consumer would in today's computer-dependent world. Previous studies have shown that online reviews of physicians are generally positive. However, 1 negative review has the potential to adversely affect business and reputations. To characterize the online presence of plastic surgeons in Southern California as portrayed by physician rating websites (PRWs). An extensive online database of board-certified plastic surgeons was used to generate a list of surgeons within a 50-mile radius of Pomona, CA. Ratings from the PRWs HealthGrades.com, Vitals.com, and UCompareHealthcare.com were cataloged by number of reviews and ratings. Two hundred sixty-three surgeons were evaluated with the most-represented cities being Beverly Hills (N=47), Los Angeles (N=31), and Newport Beach (N=27). Ninety-seven percent of the surgeons were rated on at least 1 of the 3 PRWs chosen. In general, surgeons were rated highly, with a mean rating of 85%, SD, 14% (Pconscious of their online reputations. Overall, the ratings were high, regardless of the number of reviews.

    The Syntax score has been established as a tool to determine the complexity of coronary artery disease and as a guide for decision-making among coronary artery bypass surgery and percutaneous coronary intervention. The purpose of this review is to systematically examine what the Syntax score is, and how the surgeon should integrate the information in the selection and treatment of patients. We reviewed the results of the SYNTAX Trial, the clinical practice guidelines, as well as the benefits and limitations of the score. Finally we discuss the future directions of the Syntax score.

    Pleth variability index (PVI), a noninvasive dynamic indicator of fluid responsiveness has been demonstrated to be useful in the management of the patients with goal directed fluid therapy under general anesthesia, but whether PVI can be used to optimize fluid management under combined general and epidural anesthesia (GEN-EPI) remains to be elucidated. The aim of our study was to explore the impact of PVI as a goal-directed fluid therapy parameter on the tissue perfusion for patients with GEN-EPI. Thirty ASA I-II patients scheduled for major abdominal surgeries under GEN-EPI were randomized into PVI-directed fluid management group (PVI group) and non PVI-directed fluid management group (control group). 2 mL/kg/h crystalloid fluid infusion was maintained in PVI group, once PVI>13%, a 250 mL colloid or crystalloid was rapidly infused. 4-8 mL/kg/h crystalloid fluid infusion was maintained in control group, and quick fluid infusion was initiated if mean arterial blood pressure (BP)PVI than control group, PPVI-based goal-directed fluid management can reduce the intraoperative fluid amount and blood lactate levels in patients under GEN-EPI, especially the crystalloid. Furthermore, the first hour following GEN-EPI might be the critical period for anesthesiologist to optimize the fluid management.

  17. Kant and the cosmetic surgeon.

    Carey, J S

    1989-07-01

    Philosophers know that modern philosophy owes a great debt to the intellectual contributions of the 18th century philosopher Immanuel Kant. This essay attempts to show how cosmetic surgeons, and all surgeons at that, could learn much from his work. Not only did Kant write about the structure of human reasoning and how it relates to appearances but he also wrote about the nature of duties and other obligations. His work has strongly influenced medical ethics. In a more particular way, Kant wrote the most important work on aesthetics. His theory still influences how philosophers understand the meaning of the beautiful and how it pertains to the human figure. This essay presents an exercise in trying to apply Kantian philosophy to aesthetic plastic surgery. Its intention is to show cosmetic surgeons some of the implicit and explicit philosophical principles and potential arguments undergirding their potential surgical evaluations. It is meant to challenge the surgeon to reconsider how decisions are made using philosophical reasoning instead of some of the more usual justifications based on psychology or sociology.

    Full Text Available Directional ocean wave data is usually analysed using the so-called linear model of the sea surface, but experience has shown that the results may deviate substantially from the predictions of the theory, in particular in the high frequency range. A general theory is presented here which includes the linear model as a special case. Properties of commonly used parameters under the influence of currents and non-linearities are easily explained within the general theory. Some results from the NORWAVE heave/pitch/roll data buoy operated offshore Norway are also presented.

    Full Text Available The classical Dijkstra’s algorithm to find the shortest path in graphs is not applicable to multigraphs. In this study the authors generalize the classical Dijkstra’s algorithm to make it applicable to directed multigraphs. The modified algorithm is called by Generalized Dijkstra’s algorithm or GD Algorithm (GDA in short. The GDA outputs the shortest paths and the corresponding min cost. It is claimed that GDA may play a major role in many application areas of computer science, communication, transportation systems, in particular in those networks which cannot be modeled into graphs but into multigraphs."

    2012-02-17

    Recent work by Lundeen et al. [Nature (London) 474, 188 (2011)] directly measured the wave function by weakly measuring a variable followed by a normal (i.e., "strong") measurement of the complementary variable. We generalize this method to mixed states by considering the weak measurement of various products of these observables, thereby providing the density matrix an operational definition in terms of a procedure for its direct measurement. The method only requires measurements in two bases and can be performed in situ, determining the quantum state without destroying it.

    Ranking of surgeons and hospitals focuses on procedure volume and hospitality. The National Surgical Quality Improvement Program provides vetted outcomes of surgical quality and therefore can direct improvement. Our statewide collaborative's analysis creates personalized surgeon data to drive quality improvement. Statewide National Surgical Quality Improvement Program data generated specific measures from 103,656 general/vascular cases and identified individual surgeon's outcome of occurrences and length of procedure. We assumed a normal distribution and called the top 2.5 per cent as exemplars and the bottom 2.5 per cent as outliers. For length of operation, a standard duration was calculated, and identified outliers as longer than the 95th percentile of the upper confidence interval/procedure. Since 2009, sharing best practice reduced statewide mortality rate by 31.5 per cent and postoperative morbidity by 33.3 per cent. For length of surgery, long outliers have more complications (urinary tract infection, organ space/surgical site infection, sepsis, septic shock, prolonged intubation, pneumonia, deep venous thrombosis, deep incisional infection, and wound disruption). No significant trends in surgeon performance were seen over 24 months. A statewide collaborative has resulted in substantial risk-adjusted reductions in surgical morbidity and mortality. These results of the individual surgeon demonstrate best practices are shared, a proven tool for improvement in our collaborative.

    The use of smartphones and their associated applications (apps) provides new opportunities for physicians, and specifically orthopaedic surgeons, to integrate technology into clinical practice. The purpose of this study was twofold: to review all apps specifically created for orthopaedic surgeons and to survey orthopaedic residents and surgeons in the United States to characterize the need for novel apps. The five most popular smartphone app stores were searched for orthopaedic-related apps: Blackberry, iPhone, Android, Palm, and Windows. An Internet survey was sent to ACGME-accredited orthopaedic surgery departments to assess the level of smartphone use, app use, and desire for orthopaedic-related apps. The database search revealed that iPhone and Android platforms had apps specifically created for orthopaedic surgery with a total of 61 and 13 apps, respectively. Among the apps reviewed, only one had greater than 100 reviews (mean, 27), and the majority of apps had very few reviews, including AAOS Now and AO Surgery Reference, apps published by the American Academy of Orthopaedic Surgeons and AO Foundation, respectively. The national survey revealed that 84% of respondents (n = 476) have a smartphone, the majority (55%) have an iPhone, and that 53% of people with smartphones already use apps in clinical practice. Ninety-six percent of respondents who use apps reported they would like more orthopaedic apps and would pay an average of nearly $30 for useful apps. The four most requested categories of apps were textbook/reference, techniques/guides, OITE/board review, and billing/coding. The use of smartphones and apps is prevalent among orthopaedic care providers in academic centers. However, few highly ranked apps specifically related to orthopaedic surgery are available, and the types of apps available do not appear to be the categories most desired by residents and surgeons.

    2013-08-01

    Recognizing direct relationships between variables connected in a network is a pervasive problem in biological, social and information sciences as correlation-based networks contain numerous indirect relationships. Here we present a general method for inferring direct effects from an observed correlation matrix containing both direct and indirect effects. We formulate the problem as the inverse of network convolution, and introduce an algorithm that removes the combined effect of all indirect paths of arbitrary length in a closed-form solution by exploiting eigen-decomposition and infinite-series sums. We demonstrate the effectiveness of our approach in several network applications: distinguishing direct targets in gene expression regulatory networks; recognizing directly interacting amino-acid residues for protein structure prediction from sequence alignments; and distinguishing strong collaborations in co-authorship social networks using connectivity information alone. In addition to its theoretical impact as a foundational graph theoretic tool, our results suggest network deconvolution is widely applicable for computing direct dependencies in network science across diverse disciplines.

    2015-01-01

    Our recent publication demonstrated that unprofessional behavior on Facebook is common among surgical residents. In the formulation of standards and curricula to address this issue, it is important that surgical faculty lead by example. Our current study refocuses on the Facebook profiles of faculty surgeons involved in the education of general surgery residents. The American College of Surgeons (ACS) web site was used to identify general surgery residencies located in the Midwest. Departmental web sites were then searched to identify teaching faculty for the general surgery residency. Facebook was then searched to determine which faculty had profiles available for viewing by the general public. Profiles were then placed in 1 of the 3 following categories: professional, potentially unprofessional, or clearly unprofessional. A chi-square test was used to determine significance. In all, 57 residency programs were identified on the ACS web site, 100% of which provided an institutional web site listing the surgical faculty. A total of 758 general surgery faculty were identified (133 women and 625 men), of which 195 (25.7%) had identifiable Facebook accounts. In all, 165 faculty (84.6%) had no unprofessional content, 20 (10.3%) had potentially unprofessional content, and 10 (5.1%) had clearly unprofessional content. Inter-rater reliability was good (88.9% agreement, κ = 0.784). Clearly unprofessional behavior was found only in male surgeons. For male surgeons, clearly unprofessional behavior was more common among those in practice for less than 5 years (p = 0.031). Alcohol and politics were the most commonly found variables in the potentially unprofessional group. Inappropriate language and sexually suggestive material were the most commonly found variables in the clearly unprofessional group. Unprofessional behavior on Facebook is less common among surgical faculty compared with surgical residents. However, the rates remain unacceptably high, especially among men and

    2008-03-01

    Several studies have addressed the issue of manpower needs in pediatric surgery. The number of training programs has multiplied dramatically over the past decade. The distribution of surgeons is more significant than the absolute change in numbers--are major metropolitan areas seeing a more dramatic increase than less populated areas? To evaluate the geographic and demographic changes associated with this increase, we used choropleth and geomapping techniques to evaluate the change in number and distribution of American Pediatric Surgical Association (APSA) members (and by proxy, pediatric surgeons) in the United States over the past decade. Data regarding membership were obtained from APSA. In 1996, management companies changed, and accurate data for initial year of membership were only available after 1996. Online sources (www.services.alphaworks.ibm.com/manyeyes/home and www.mapresso.com) were used for data analysis. There was a 175% increase in the number of APSA members over the past decade. The geographic distribution parallels the state population to some extent but is uneven. The number of APSA members by state over time is displayed in color density maps. Predictions of prior manpower studies were generally accurate. The number of pediatric surgeons in the United States has rapidly increased in the past decade, with no sign of diminution in this trend. Increases in the number of surgeons correlates with state population, indicating a tendency for surgeons to reside in more densely populated areas, as expected. Areas with a disproportionately high or low number of surgeons can be identified via choropleth mapping.

    2014-09-01

    Surgeons are the physicians with the highest rates of documented disruptive behavior. We hypothesized that a unified conceptual model of disruptive surgeon behavior could be developed based on specific individual and system factors in the perioperative environment. Semi-structured interviews were conducted with 19 operating room staff of diverse occupations at a single institution. Interviews were analyzed using grounded theory methods. Participants described episodes of disruptive surgeon behavior, personality traits of perpetrators, environmental conditions of power, and situations when disruptive behavior was demonstrated. Verbal hostility and throwing or hitting objects were the most commonly described disruptive behaviors. Participants indicated that surgical training attracts and creates individuals with particular personality traits, including a sense of shame. Interviewees stated this behavior is tolerated because surgeons have unchecked power, have strong money-making capabilities for the institution, and tend to direct disruptive behavior toward the least powerful employees. The most frequent situational stressors were when something went wrong during an operation and working with unfamiliar team members. Each factor group (ie, situational stressors, cultural conditions, and personality factors) was viewed as being necessary, but none of them alone were sufficient to catalyze disruptive behavior events. Disruptive physician behavior has strong implications for the work environment and patient safety. This model can be used by hospitals to better conceptualize conditions that facilitate disruptive surgeon behavior and to establish programs to mitigate conduct that threatens patient safety and employee satisfaction.

    Under the Physician Payments Sunshine Act, "payments or transfers of value" by biomedical companies to physicians must be disclosed through the Open Payments Program. Designed to provide transparency of financial transactions between medication and device manufacturers and health care providers, the Open Payments Program shows financial relationships between industry and health care providers. Awareness of this program is crucial because its interpretation or misinterpretation by patients, physicians, and the general public can affect patient care, clinical practice, and research. This study evaluated nonresearch payments by industry to orthopedic surgeons. A retrospective cross-sectional review of the first wave of Physician Payments Sunshine Act data (August through December 2013) was performed to characterize industry payments to orthopedic surgeons by subspecialty, amount, type, origin, and geographic distribution. During this 5-month period, orthopedic surgeons (n=14,828) received $107,666,826, which included 3% of those listed in the Open Payments Program and 23% of the total amount paid. Of orthopedic surgeons who received payment, 45% received less than $100 and 1% received $100,000 or more. Median payment (interquartile range) was $119 ($34-$636), and mean payment was $7261±95,887. The largest payment to an individual orthopedic surgeon was $7,849,711. The 2 largest payment categories were royalty or license fees (68%) and consulting fees (13%). During the study period, orthopedic surgeons had substantial financial ties to industry. Of orthopedic surgeons who received payments, the largest proportion (45%) received less than $100 and only 1% received large payments (≥$100,000). The Open Payments Program offers insight into industry payments to orthopedic surgeons. [Orthopedics. 2016; 39(6):e1058-e1062.]. Copyright 2016, SLACK Incorporated.

    nerve regeneration and nerve grafting, and after many years of devoted research, he devised successful operations for facial nerve paralysis. For this and early vascular work, he is often credited as the first English surgeon to reintroduce classical Hunterian methods of experiment into surgery. He was honored as the founder and President of The Society of British Neurological Surgeons in 1926. Perhaps best known as a general and aural surgeon, Ballance was second only to Horsley in reputation as a pioneer British neurological surgeon. Described as a painstakingly slow but delicate and meticulous operator, Ballance made a contribution to neurosurgery and temporal bone surgery that was immense.

    Handedness is perhaps the most studied human asymmetry. Laterality is the preference shown for one side and it has been studied in many aspects of medicine. Studies have shown that some orthopaedic procedures had poorer outcomes and identified laterality as a contributing factor. We developed a questionnaire to assess laterality in orthopaedic surgery and compared this to an established scoring system. Sixty-two orthopaedic surgeons surveyed with the validated Waterloo Handedness Questionnaire (WHQ) were compared with the self developed Orthopaedic Handedness Questionnaire (OHQ). Fifty-eight were found to be right hand dominant (RHD) and 4 left hand dominant (LHD). In RHD surgeons, the average WHQ score was 44.9% and OHQ 15%. For LHD surgeons the WHQ score was 30.2% and OHQ 9.4%. This represents a significant amount of time using the non dominant hand but does not necessarily determine satisfactory or successful dexterity transferable to the operating room. Training may be required for the non dominant side.

    To ensure qualified health care professionals at public hospitals in the future, it is important to understand which factors attract health care professionals to certain positions. The aim of this study was to explore motives for choosing employment at either public or private hospitals in a group of Danish surgeons, as well as to examine if organizational characteristics had an effect on motivation. Eight qualitative interviews were conducted with surgeons from both public and private hospitals sampled using the snowball method. The interviews were based on a semi-structured interview guide and analyzed by means of phenomenological theory. Motivational factors such as personal influence on the job, the opportunity to provide the best possible patient care, challenging work tasks colleagues, and ideological reasons were emphasized by the surgeons as important reasons for their choice of employment. Motivational factors appeared to be strongly connected to the structure of the organization; especially the size of the organization was perceived to be essential. It is worth noting that salary, in contrast to the general belief, was considered a secondary benefit rather than a primary motivational factor for employment. The study revealed that motivational factors are multidimensional and rooted in organizational structure; i.e. organizational size rather than whether the organization is public or private is crucial. There is a need for further research on the topic, but it seems clear that future health care planning may benefit from taking into account the implications that large organizational structures have for the staff working within these organizations. not relevant. not relevant.

    Endosomal entrapment is a key hurdle for most intracellular protein-based therapeutic strategies. We report a general strategy for efficient delivery of proteins to the cytosol through co-engineering of proteins and nanoparticle vehicles. The proteins feature an oligo(glutamate) sequence (E-tag) that binds arginine-functionalized gold nanoparticles, generating hierarchical spherical nanoassemblies. These assemblies fuse with cell membranes, releasing the E-tagged protein directly into the cytosol. Five different proteins with diverse charges, sizes, and functions were effectively delivered into cells, demonstrating the generality of our method. Significantly, the engineered proteins retained activity after cytosolic delivery, as demonstrated through the delivery of active Cre recombinase, and granzyme A to kill cancer cells.

  13. Cooperative Output Regulation of Nonlinear Multiagent Systems under a General Directed Graph

    2015-01-01

    Full Text Available This paper studies the cooperative output regulation problem for a class of nonlinear multiagent systems modeled by nonlinear dynamics under a general directed communication topology. A type of distributed internal model is introduced to convert the cooperative output regulation problem into a robust stabilization problem of a so-called augmented system. Based on the Lyapunov stability theorem and M-matrix theorem, a kind of distributed output feedback controller only using the relative outputs of neighboring agents together with its stability analysis is further proposed with the aid of the backstepping technology, under which the outputs of the followers will asymptotically converge to that of the leader if, for each follower, there exists at least a directed path from the leader to the follower. Finally, a numerical example is provided to illustrate the effectiveness of the analytic results.

    2012-01-01

    A graph is said to be a cover graph if it is the underlying graph of the Hasse diagram of a finite partially ordered set. The direct product G X H of graphs G and H is the graph having vertex set V(G) X V(H) and edge set E(G X H) = {(g_i,h_s)(g_j,h_t): g_ig_j belongs to E(G) and h_sh_t belongs to E(H)}. We prove that the direct product M_m(G) X M_n(H) of the generalized Mycielskians of G and H is a cover graph if and only if G or H is bipartite.

  15. The Directed Dominating Set Problem: Generalized Leaf Removal and Belief Propagation

    2015-01-01

    A minimum dominating set for a digraph (directed graph) is a smallest set of vertices such that each vertex either belongs to this set or has at least one parent vertex in this set. We solve this hard combinatorial optimization problem approximately by a local algorithm of generalized leaf removal and by a message-passing algorithm of belief propagation. These algorithms can construct near-optimal dominating sets or even exact minimum dominating sets for random digraphs and also for real-world digraph instances. We further develop a core percolation theory and a replica-symmetric spin glass theory for this problem. Our algorithmic and theoretical results may facilitate applications of dominating sets to various network problems involving directed interactions.

    2016-01-01

    Optically active artificial structures have attracted tremendous research attention. Such structures must meet two requirements: Lack of spatial inversion symmetries and, a condition usually not explicitly considered, the structure shall preserve the helicity of light, which implies that there must be a vanishing coupling between the states of opposite polarization handedness among incident and scattered plane waves. Here, we put forward and demonstrate that a unit cell made from chiraly arranged electromagnetically dual scatterers serves exactly this purpose. We prove this by demonstrating optical activity of such unit cell in general scattering directions.

  17. Diagonal Loading of Robust General-Rank Beamformer for Direction of Arrival Mismatch

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available This study presents a technique which utilizes the movement of the peak of the main beam towards the presumed signal direction with negative diagonal loading for robust general-rank beamformer. The main beam symmetry along presumed signal direction is improved by this movement. When desired signal is contained in the data snapshots, the conventional beamformers face the problem of performance degradation even if there is a small mismatch between the presumed and the actual signal direction. Diagonal loading is a popular technique to mitigate this problem. There is no definite criterion to find diagonal loading level. A new diagonal loading method has been proposed in the literature which utilizes the movement of the peak of main beam towards the presumed signal direction with positive diagonal loading. The proposed technique works iteratively for the selection of negative diagonal loading level to move the main beam at a position to get the beam symmetry at desired level and hence the desired robustness. The mismatched signal will not be cancelled as long as it is within the half of the width of the main beam. But there is the tradeoff between this robustness and interference cancelling capability.

    We sought to compare postoperative outcomes of female surgeons (FS) and male surgeons (MS) within general surgery. FS in the workforce are increasing in number. Female physicians provide exceptional care in other specialties. Differences in surgical outcomes of FS and MS have not been examined. We linked the AMA Physician Masterfile to discharge claims from New York, Florida, and Pennsylvania (2012 to 2013) to examine practice patterns and to compare surgical outcomes of FS and MS. We paired FS and MS operating at the same hospital using cardinality matching with refined balance and compared inpatient mortality, any postoperative complication, and prolonged length of stay (pLOS) in FS and MS. Overall practice patterns differed between the 663 FS and 3219 MS. We identified 2462 surgeons (19% FS, 81% MS) at 429 hospitals who met inclusion criteria for outcomes analysis. FS were younger (mean age ± SD FS: 48.5 ± 8.4 years, MS: 54.3 ± 9.4y; P best fit for them regardless of sex.

    Acute hepatobiliary pathology is a common general surgical emergency referral. Diagnosis requires imaging of the biliary tree by ultrasonography. The accuracy and impact of surgeon-performed ultrasonography (SUS) on the diagnosis of emergent hepatobiliary pathology was examined. A prospective study, over a 6-month period, enrolled all patients with symptoms or signs of acute hepatobiliary pathology. Patients provided informed consent and underwent both SUS and standard radiology-performed ultrasonography (RUS). SUS was performed using a 2-5-MHz broadband portable ultrasound probe by two surgeons trained in ultrasonography, and RUS using a 2-5-MHz fixed unit. SUS results were correlated with those of RUS and pathological diagnoses. Fifty-three consecutive patients underwent 106 ultrasonographic investigations. SUS agreed with RUS in 50 (94.3 per cent) of 53 patients. SUS accurately detected cholelithiasis in all but two cases and no patient was inaccurately diagnosed as having cholelithiasis at SUS (95.2 per cent sensitivity and 100 per cent specificity). As an overall complementary diagnostic tool SUS provided the correct diagnosis in 96.2 per cent of patients. Time to scan was significantly shorter following SUS (3.1 versus 12.0 h, P < 0.05). SUS provides a rapid and accurate diagnosis of emergency hepatobiliary pathology and may contribute to the emergency management of hepatobiliary disease.

    The importance of non-technical skills to surgical performance is gaining wide acceptance. This article discusses the core cognitive and social skills categories thought to underpin medical knowledge and surgical expertise, and describes the rise of non-technical skill models of assessment in surgery. Behavior rating systems such as NOTSS (Non-Technical Skills for Surgeons) have been developed to support education and assessment in this regard. We now understand more about these critical skills and how they impact surgery. The challenge in the future is to incorporate them into undergraduate teaching, postgraduate training, workplace assessment, and perhaps even selection.

    Genitourinary prosthetics are used for correction of functional deficits and to improve the quality of lives of affected patients. General surgeons must evaluate patients scheduled for nonurologic surgery with urologic devices that can impact their perioperative management. Lack of recognition of these prosthetics preoperatively can lead to unnecessary morbidity for the patient and have legal implications for the surgeon. Close consultation with a urologist may avoid common complications associated with these devices and allows for surgical assistance when operative misadventures do occur. This article reviews 3 common urologic prosthetics: testicular prosthesis, artificial urinary sphincter, and penile prosthesis.

    Full Text Available Background and Objectives: To characterize the impact of pregabalin on sleep in patients with generalized anxiety disorder (GAD and to determine whether the impact is a direct or an indirect effect, mediated through the reduction of anxiety symptoms. Methods: A post-hoc analysis of data from a randomized, double-blind, placebo- and active-controlled study in patients with GAD was conducted. Patients received pregabalin 300 mg/day, venlafaxine XR 75 mg/day or placebo for a week, followed by pregabalin 300-600 mg/day, venlafaxine XR 75-225 mg/day, or placebo for 7 weeks. Treatment effect on sleep was evaluated using the Medical Outcomes Study Sleep Scale. Anxiety symptoms were assessed with the Hamilton Anxiety Rating Scale. A mediation model was used to estimate separately for both treatment arms the direct and indirect treatment effects on sleep disturbance. Results: Compared with placebo (n = 128, treatment with pregabalin (n = 121 significantly reduced scores on the sleep disturbance subscale and Sleep Problems Index II at both week 4 and week 8, and the sleep adequacy subscale at week 8. Venlafaxine XR (n = 125 had no significant effect on these measures. The mediation model indicated that 53% of the total pregabalin effect on sleep disturbance was direct (p < 0.01 and 47% indirect, mediated through anxiety symptoms (p < 0.05. Conclusions: Pregabalin decreased sleep disturbance in patients with GAD both directly, and indirectly by reducing anxiety symptoms. Given the drug specificity of the results, this study provides evidence of an additional important pathway of action for pregabalin and its efficacy in GAD.

    The aim of this study was to determine the prevalence of burnout syndrome among Brazilian oral and maxillofacial surgeons and its relationship with socio-demographic, clinical, and habit variables. The sample of this study comprised 116 surgeons. The syndrome was quantified using the Maslach Burnout Inventory (General Survey), which defines burnout as the triad of high emotional exhaustion, high depersonalization, and low personal accomplishment. The criteria of Grunfeld et al. were used to evaluate the presence of the syndrome (17.2%). No significant differences between the surgeons diagnosed with and without the syndrome were observed according to age (P=0.804), sex (P=0.197), marital status (P=0.238), number of children (P=0.336), years of professional experience (P=0.102), patients attended per day (P=0.735), hours worked per week (P=0.350), use of alcohol (P=0.148), sports practice (P=0.243), hobbies (P=0.161), or vacation period per year (P=0.215). Significant differences occurred in the variables sex in the emotional exhaustion subscale (P=0.002) and use or not of alcohol in the personal accomplishment subscale (P=0.035). Burnout syndrome among Brazilian surgeons is average, showing a low personal accomplishment. Copyright © 2014 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    Assessment and remedial clinical education of practicing surgeons is feasible and possibly beneficial. Retrospective series. Urban academic medical center. Licensed surgeons. Structured assessment and remedial clinical education based on resident-education models. Assessment and clinical education results. Forty-seven general, general/vascular, and colorectal surgeons were assessed by the University of California, San Diego, Physician Assessment and Clinical Education program in 2000 to 2010. Forty-six (98%) were male (mean [SD] age, 54 [11] years; range, 34-80 years). Thirty-three (70%) came from state medical board actions: 25 from California's disciplinary division, 2 from California's licensing division, 3 from other state boards, and 3 self-referred during other state board actions. Fourteen (30%) came from health care organizations: 8 from California hospitals, 3 from hospitals in other states, 2 self-referred during hospital proceedings, and 1 self-referred during a medical group investigation. Twenty-three (49%) underwent a 2-day assessment only, including a 1-hour mock oral board examination: 8 "passed" with no recommendations; 6, with minor recommendations; 6 had major recommendations; and 3 "failed." Twenty-four surgeons (51%) also completed 26 five-day clinical education programs, with 20 "passes," 1 minor recommendation, 3 major recommendations, and 2 "fails." A program of assessment and remedial clinical education of surgeons designed to meet the needs of one medical board is being used by nongovernmental organizations as well, and it seems to meet the needs of some individual surgeons. This type of program may play a role in the profession's self-regulation.

  12. Impact of Surgeon Experience During Carotid Endarterectomy Operation and Effects on Perioperative Outcomes

    Directory of Open Access Journals (Sweden)

    Volkan Yüksel

    Full Text Available Abstract Objective: We evaluated the effect of surgeon experience on complication and mortality rates of carotid endarterectomy operation. Methods: Fifty-nine consecutive patients who underwent carotid endarterectomy between January 2013 and February 2016 were divided into two groups. Patients who had been operated by surgeons performing carotid endarterectomy for more than 10 years were allocated to group 1 (experienced surgeons; n=34. Group 2 (younger surgeons; n=25 consisted of patients operated by surgeons independently performing carotid endarterectomy for less than 2 years. Both groups were compared in respect of operative results and postoperative complications. Results: No intergroup difference was found for laterality of the lesion or concomitant coronary artery disease. In group 1, signs of local nerve damage (n=2; 5.9% were detected, whereas in group 2 no evidence of local nerve damage was observed. Surgeons in group 1 used local and general anesthesia in 3 (8.8% and 31 (91.2% patients, respectively, while surgeons in group 2 preferred to use local and general anesthesia in 1 (4% and 24 (96% patients, respectively. Postoperative stroke was observed in group 1 (n=2; 5.9% and group 2 (n=2; 5.8%. Conclusion: Younger surgeons perform carotid endarterectomy with similar techniques and have similar results compared to experienced surgeons. Younger surgeons rarely prefer using shunt during carotid endarterectomy. The experience and the skills gained by these surgeons during their training, under the supervision of experienced surgeons, will enable them to perform successful carotid endarterectomy operations independently after completion of their training period.

    Lorincz, Attila; Langenburg, Scott; Klein, Michael D

    2003-06-01

    Surgical robots are enabling devices for minimally invasive (laparoscopic) surgery (MIS). They use a computer to enhance a surgeon's skills as hand movements are transmitted to robotic arms. The computer filters tremor, which becomes important at high magnifications of 10 to 15 times available in MIS. It also provides motion scaling so that large hand movements are converted to very small movements of the robotic arm. The robotic arms also have wrists that make suturing and knot tying far more accurate and efficient. Surgical robots are currently used clinically for procedures such as MIS Nissen fundoplication, cholecystectomy, and splenectomy. Laboratory experience indicates that they may provide advantages for newborn procedures such as portoenterostomy for biliary atresia and repair of esophageal atresia and tracheoesophageal fistula. They have a potential for making possible MIS procedures, which can only be done open now, and for introducing entirely new procedures as well as for the performance of procedures by operators distant from the patient.

    The purpose of this study is to determine which patient- and tumor-related and clinical variables influence dedicated breast surgeons' and general surgeons' referrals for preoperative breast MRI for patients with newly diagnosed breast cancer. Surgeons who perform breast surgery responded to a survey from June 16, 2014, through August 11, 2014. Participants self-identified as breast or general surgeons and provided professional practice details. They used Likert scores (range, 1-7 with increasing likelihood to order MRI) to weigh numerous patient- and tumor-related and clinical variables. Mean likelihood scores were calculated and compared using a linear mixed model. A p ≤ 0.05 was considered statistically significant. Two hundred eighty-nine surveys from 154 (53%) breast surgeons and 135 (47%) general surgeons showed an overall likelihood to refer for patients with a BRCA mutation (mean Likert score, 6.17), familial (mean Likert score, 5.33) or personal (mean Likert score, 5.10) breast cancer history, extremely dense breasts (mean Likert score, 5.30), age younger than 40 years (mean Likert score, 5.24), axillary nodal involvement (mean Likert score, 6.22), tumor that is mammographically occult (mean Likert score, 5.62) or fixed to the pectoralis (mean Likert score, 5.49), tumor that is a candidate for neoadjuvant treatment (mean Likert score, 5.38), multifocal or multicentric disease (mean Likert score, 5.22), invasive lobular carcinoma (mean Likert score, 5.20), T3 (mean Likert score, 4.48) or T2 (mean Likert score, 4.41) tumor, triple-negative breast cancer (mean Likert score, 4.66), a patient who is a candidate for mastectomy requesting breast conservation therapy (mean Likert score, 5.27), and radiologists' recommendations (mean Likert score, 5.19). Across all patient ages, breast surgeons referred more often than did general surgeons (mean Likert score, 4.32 vs 3.92; p = 0.03), especially for patients with BRCA mutation (mean Likert score, 6.39 vs 5.93; p

  17. Adaptive finite element modeling of direct current resistivity in 2-D generally anisotropic structures

    Science.gov (United States)

    Yan, Bo; Li, Yuguo; Liu, Ying

    2016-07-01

    In this paper, we present an adaptive finite element (FE) algorithm for direct current (DC) resistivity modeling in 2-D generally anisotropic conductivity structures. Our algorithm is implemented on an unstructured triangular mesh that readily accommodates complex structures such as topography and dipping layers and so on. We implement a self-adaptive, goal-oriented grid refinement algorithm in which the finite element analysis is performed on a sequence of refined grids. The grid refinement process is guided by an a posteriori error estimator. The problem is formulated in terms of total potentials where mixed boundary conditions are incorporated. This type of boundary condition is superior to the Dirichlet type of conditions and improves numerical accuracy considerably according to model calculations. We have verified the adaptive finite element algorithm using a two-layered earth with azimuthal anisotropy. The FE algorithm with incorporation of mixed boundary conditions achieves high accuracy. The relative error between the numerical and analytical solutions is less than 1% except in the vicinity of the current source location, where the relative error is up to 2.4%. A 2-D anisotropic model is used to demonstrate the effects of anisotropy upon the apparent resistivity in DC soundings.

    To determine the incidence of burnout among American surgeons and evaluate personal and professional characteristics associated with surgeon burnout. : Burnout is a syndrome of emotional exhaustion and depersonalization that leads to decreased effectiveness at work. A limited amount of information exists about the relationship between specific demographic and practice characteristics with burnout among American surgeons. Members of the American College of Surgeons (ACS) were sent an anonymous, cross-sectional survey in June 2008. The survey evaluated demographic variables, practice characteristics, career satisfaction, burnout, and quality of life (QOL). Burnout and QOL were measured using validated instruments. Of the approximately 24,922 surgeons sampled, 7905 (32%) returned surveys. Responders had been in practice 18 years, worked 60 hours per week, and were on call 2 nights/wk (median values). Overall, 40% of responding surgeons were burned out, 30% screened positive for symptoms of depression, and 28% had a mental QOL score >1/2 standard deviation below the population norm. Factors independently associated with burnout included younger age, having children, area of specialization, number of nights on call per week, hours worked per week, and having compensation determined entirely based on billing. Only 36% of surgeons felt their work schedule left enough time for personal/family life and only 51% would recommend their children pursue a career as a physician/surgeon. Burnout is common among American surgeons and is the single greatest predictor of surgeons' satisfaction with career and specialty choice. Additional research is needed to identify individual, organizational, and societal interventions that preserve and promote the mental health of American surgeons.

    Bilateral Breast Reduction (BBR) is a common procedure performed by Breast and Plastic surgeons in the UK. No consensus exists regarding preoperative screening for malignancy or for selective criteria for such screening. Preoperative BBR screening practices among UK Breast and Plastic surgeons are unknown. Ascertain the preoperative and postoperative BBR screening practices of UK Breast and Plastic surgeons. A questionnaire was posted to all 434 Breast and 335 Plastic surgeons in the UK. All results were analysed with relevant statistical methods. 64% of Breast surgeons and 72% of Plastic surgeons responded. 40% of Breast surgeons and 91% of Plastic surgeons perform BBR. Routine radiological screening: 92% Breast 41% Plastic (p Plastic. Routine histology for BBR specimens: 96% Breast 90% Plastic. Selective screening of patients aged 30-40 years old: Breast 38% Plastic 10%. Selective screening of patients aged 40-50: Breast 78%, Plastic 53%. Selective screening of patients with strong family history of breast cancer: Breast 72%, Plastic 91%. Selective screening of patients with previous breast cancer: Breast 77%, Plastic 93%. There are significant differences in practice between UK Breast surgeons and Plastic surgeons in preoperative oncological screening for BBR. The large discrepancy in preoperative radiological screening, reflects a ubiquitous pro-screening ideology among Breast surgeons not prevalent among Plastic surgeons. These results will provoke debate towards the direction of consensus to ultimately reflect best practice. Copyright © 2010. Published by Elsevier Ltd.

    The New Zealand Medical Association commits the New Zealand doctor to evidence-based medicine, scholarship, teaching, collaboration and communication. To assess this commitment, one measure, contribution to the peer-reviewed literature, was examined for one group of New Zealand doctors: plastic surgeons. Plastic surgeons with a current practising certificate were identified on the New Zealand medical register (April 2016). Scopus database was searched for publications by each. Sixty-five surgeons authored 541 unique items in 134 journals, generating 8,047 citations. Between medical graduation and specialty qualification, a mean 1.8 items were published per practitioner (range 0-11). Twenty-three practitioners (35.4%) did not publish during this time. Between specialty qualification and the end of 2015, mean number of items published per surgeon was 7.3 (range 0-97). Thirteen (20.0%) surgeons had not published since specialist qualification. The general trend was for surgeons to become less productive with increasing time in practice. Mean surgeon h-index was 4.4 (range 0-26). Four surgeons (6.2%) had not published at any time. As a group, but with exceptions and less so in later practice, New Zealand plastic surgeons would seem to demonstrate commitment to evidence-based medicine, scholarship, teaching, collaboration and communication expected of a New Zealand doctor, as evidenced by peer-review publication.

    In a dynamic health care system, strong leadership has never been more important for surgeons. Little is known about how to design and conduct effectively a leadership program specifically for surgeons. We sought to evaluate critically a Leadership Development Program for practicing surgeons by exploring how the program's strengths and weaknesses affected the surgeons' development as physician-leaders. At a large academic institution, we conducted semistructured interviews with 21 surgical faculty members who applied voluntarily, were selected, and completed a newly created Leadership Development Program in December 2012. Interview transcripts underwent qualitative descriptive analysis with thematic coding based on grounded theory. Themes were extracted regarding surgeons' evaluations of the program on their development as physician-leaders. After completing the program, surgeons reported personal improvements in the following 4 areas: self-empowerment to lead, self-awareness, team-building skills, and knowledge in business and leadership. Surgeons felt "more confident about stepping up as a leader" and more aware of "how others view me and my interactions." They described a stronger grasp on "giving feedback" as well as a better understanding of "business/organizational issues." Overall, surgeon-participants reported positive impacts of the program on their day-to-day work activities and general career perspective as well as on their long-term career development plans. Surgeons also recommended areas where the program could potentially be improved. These interviews detailed self-reported improvements in leadership knowledge and capabilities for practicing surgeons who completed a Leadership Development Program. A curriculum designed specifically for surgeons may enable future programs to equip surgeons better for important leadership roles in a complex health care environment. Copyright © 2016 Elsevier Inc.

    Much of the decision-making in orthopaedics rests on uncertain evidence. Uncertainty is therefore part of our normal daily practice, and yet physician uncertainty regarding treatment could diminish patients' health. It is not known if physician uncertainty is a function of the evidence alone or if other factors are involved. With added experience, uncertainty could be expected to diminish, but perhaps more influential are things like physician confidence, belief in the veracity of what is published, and even one's religious beliefs. In addition, it is plausible that the kind of practice a physician works in can affect the experience of uncertainty. Practicing physicians may not be immediately aware of these effects on how uncertainty is experienced in their clinical decision-making. We asked: (1) Does uncertainty and overconfidence bias decrease with years of practice? (2) What sociodemographic factors are independently associated with less recognition of uncertainty, in particular belief in God or other deity or deities, and how is atheism associated with recognition of uncertainty? (3) Do confidence bias (confidence that one's skill is greater than it actually is), degree of trust in the orthopaedic evidence, and degree of statistical sophistication correlate independently with recognition of uncertainty? We created a survey to establish an overall recognition of uncertainty score (four questions), trust in the orthopaedic evidence base (four questions), confidence bias (three questions), and statistical understanding (six questions). Seven hundred six members of the Science of Variation Group, a collaboration that aims to study variation in the definition and treatment of human illness, were approached to complete our survey. This group represents mainly orthopaedic surgeons specializing in trauma or hand and wrist surgery, practicing in Europe and North America, of whom the majority is involved in teaching. Approximately half of the group has more than 10 years

    Previous studies have demonstrated correlations between personality traits and job performance and satisfaction. Evidence suggests that personality differences exist between surgeons and nonsurgeons, some of which may develop during medical training. Understanding these personality differences may help optimize job performance and satisfaction among surgical trainees and be used to identify individuals at risk of burnout. This study aims to identify personality traits of surgeons and nonsurgeons at different career points. We used The Big Five Inventory, a 44-item measure of the five factor model. Personality data and demographics were collected from responses to an electronic survey sent to all faculty and house staff in the Departments of Surgery, Medicine, and Family Medicine at The Ohio State University College of Medicine. Data were analyzed to identify differences in personality traits between surgical and nonsurgical specialties according to level of training and to compare surgeons to the general population. One hundred ninety-two house staff and faculty in surgery and medicine completed the survey. Surgeons scored significantly higher on conscientiousness and extraversion but lower on agreeableness compared to nonsurgeons (all P personality differences between surgical and nonsurgical specialties. The use of personality testing may be a useful adjunct in the residency selection process for applicants deciding between surgical and nonsurgical specialties. It may also facilitate early intervention for individuals at high risk for burnout and job dissatisfaction. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Leadership theory: implications for developing dental surgeons in primary care?

    Science.gov (United States)

    Willcocks, S

    2011-02-12

    The development of leadership in healthcare has been seen as important in recent years, particularly at the clinical level. There have been various specific initiatives focusing on the development of leadership for doctors, nurses and other health care professions: for example, a leadership competency framework for doctors, the LEO programme and the RCN clinical leadership programme for nurses. The NHS has set up a Leadership Council to coordinate further developments. However, there has not been the same focus in dentistry, although the recent review of NHS dental services (Steele review) has proposed a need for leadership initiatives in NHS dentistry as a medium-term action. Central to this will be a need to focus on the leadership role for dental surgeons. Leadership is all the more important in dentistry, given the change of government and the policy of retrenchment, major public sector reform, the emergence of new organisations such as new commissioning consortia, possible changes to the dental contract, new ways of working, and changes to the profession such as the requirements for the revalidation of dental surgeons. The question is: which leadership theory or approach is best for dental surgeons working in primary care? This paper builds on earlier work exploring this question in relation to doctors generally, and GPs, in particular, and planned work on nurses. It will seek to address this question in relation to dental surgeons working in primary care.

  8. Surgeon's view of the skull base from the lateral approach.

    Science.gov (United States)

    Goldenberg, R A

    1984-12-01

    This paper presents the surgical anatomy of the skull base and infratemporal fossa. The information has been derived from the author's own experience in surgical and cadaver dissection, standard anatomical references, and selected experience of other skull base surgeons. Because the lateral approach has become the utilitarian method of exposure, the intricate detailed anatomy is demonstrated from this view at five levels of dissection, so the surgeon may gain a practical understanding of the surgical relationship of critical structures. Consistent anatomical landmarks can be used by the surgeon in the location of these critical structures. The styloid process, sphenoidal spine, and middle meningeal artery identify the internal carotid artery as it enters the carotid canal. The bony or fibrous septum that divides the jugular foramen into neural and vascular compartments may be used to better identify nerves IX, X, and XI. The zygomatic root is useful for location of the middle fossa dura. The lateral pterygoid plate leads directly to the foramen ovale. The increased precision of dissection permitted by use of the microscope requires an increased level of knowledge of anatomical structures in this area. It is hoped that the information presented in this paper will assist surgeons in the meticulous and thorough removal of skull base tumors and in the preservation of neural and vascular structures that are presently being sacrificed.

  9. The surgeon and human immunodeficiency virus.

    The moral dilemmas faced by surgeons worldwide who treat patients infected with the human immunodeficiency virus (HIV) can be viewed against the background of experience in sub-Saharan countries, where the community prevalence is in excess of 25% (90% of hospital inpatients). When seeking consent for an HIV test before surgery, frank communication regarding the surgeons' perspective of risks to themselves and the patient is helpful. When consent for a test must be obtained from a substitute decision-maker, the surgeon should consider if the patient would want the decision-maker to know the result. Understanding the natural history of HIV in the surgical setting can help deal with the uncertainties encountered and should be a research priority for developing countries. International professional organizations are useful platforms for the exchange of ideas when surgeons encounter uncertainty by increasing access to journals and creating opportunities for discussion. Although supervisory bodies in some parts of the world prevent HIV-infected surgeons from putting patients at risk by offering surgery, the withdrawal of their services in developing countries can cause more harm than good. Surgeons in that position may be entitled to offer surgery but only with full disclosure of the risk of HIV infection to the patient. The decision-making process known as "accountability for reasonableness" allows surgeons to determine fairness, legitimacy, and acceptability when making resource allocation decisions involving patients with HIV.

    2015-11-01

    Since the days of Sushruta, innovation has shaped the history of plastic surgery. Plastic surgeons have always been known as innovators or close followers of innovations. With this descriptive international survey study, the authors aimed to evaluate the future of plastic surgeons by analyzing how plastic surgery and plastic surgeons will be affected by new trends in medicine. Aesthetic surgery is the main subclass of plastic surgery thought to be the one that will change the most in the future. Stem cell therapy is considered by plastic surgeons to be the most likely "game changer." Along with changes in surgery, plastic surgeons also expect changes in plastic surgery education. The most approved assumption for the future of plastic surgery is, "The number of cosmetic nonsurgical procedures will increase in the future." If surgeons want to have better outcomes in their practice, they must at least be open minded for innovations if they do not become innovators themselves. Besides the individual effort of each surgeon, international and local plastic surgery associations should develop new strategies to adopt these innovations in surgical practice and education.

  11. Skeletal metastases - the role of the orthopaedic and spinal surgeon.

    2012-09-01

    Developments in oncological and medical therapies mean that life expectancy of patients with metastatic bone disease (MBD) is often measured in years. Complications of MBD may dramatically and irreversibly affect patient quality of life, making the careful assessment and appropriate management of these patients essential. The roles of orthopaedic and spinal surgeons in MBD generally fall into one of four categories: diagnostic, the prophylactic fixation of metastatic deposits at risk of impending fracture (preventative surgery), the stabilisation or reconstruction of bones affected by pathological fractures (reactive surgery), or the decompression and stabilisation of the vertebral column, spinal cord, and nerve roots. Several key principals should be adhered to whenever operating on skeletal metastases. Discussions should be held early with an appropriate multi-disciplinary team prior to intervention. Detailed pre-assessment is essential to gauge a patient's suitability for surgery - recovery from elective surgery must be shorter than the anticipated survival. Staging and biopsies provide prognostic information. Primary bone tumours must be ruled out in the case of a solitary bone lesion to avoid inappropriate intervention. Prophylactic surgical fixation of a lesion prior to a pathological fracture reduces morbidity and length of hospital stay. Regardless of a lesion or pathological fracture's location, all regions of the affected bone must be addressed, to reduce the risk of subsequent fracture. Surgical implants should allow full weight bearing or return to function immediately. Post-operative radiotherapy should be utilised in all cases to minimise disease progression. Spinal surgery should be considered for those with spinal pain due to potentially reversible spinal instability or neurological compromise. The opinion of a spinal surgeon should be sought early, as delays in referral directly correlate to worse functional recovery following intervention

    2008-02-01

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

    Introduction: Most everyday activities, performed over a long period leads to performance degradation of skeletal muscles as well as spinal column which is reflected in the reduction of maximum force, reduction of the speed of response, reducing control of the movement etc. Although until now many mathematical models of muscles are developed, very small number takes into account the fatigue, and those models that take into account changes in the characteristics of muscles for extended activities, generally considered tiring under certain conditions. Given that the current models of muscle fatigue under arbitrary conditions of activation and load are very limited, this article presents a new model that includes scale of muscles overload. Material and Methods: There are three female cardiac surgeons working performing these surgeries in operating rooms, and their average anthropometric measures for this population is: a) Weight: 62 kg; b) Height: 166 cm.

We wish to emphasize that the experiment or surgical procedure lasted for two positions for five hours, with the position “1” lasted 0.5 hours, and position “2” lasted about 4.5 hours. The additional load arm during surgery is about 1.0 kg. Results: The analysis was done in three positions: “Operating position 1”, “Operating position 2 ‘, and each of these positions will be considered in its characteristic segments. These segments are: when the body takes the correct position, but is not yet burdened with external load, then when the surgeon receives the load and the third position when the load is lifted at the end of the position.

    2017-06-01

    Surgeons are increasingly performing procedures on awake patients. Communication during such procedures is complex and underexplored in the literature. Surgeons were recruited from the faculty of 2 hospitals to participate in an interview regarding their approaches to communication during awake procedures. Three researchers used the constant comparative method to transcribe, code, and review interviews until saturation was reached. Twenty-three surgeons described the advantages and disadvantages of awake procedures, their communication with the awake patient, their interactions with staff and with trainees, the environment of awake procedures, and how communication in this context is taught and learned. Surgeons recognized communication during awake procedures as important and reported varied strategies for ensuring patient comfort in this context. However, they also acknowledged challenges with multiparty communication during awake procedures, especially in balancing commitments to teaching with their duty to comfort the patient.

    The generalized hard sphere model which incorporates the effects of attraction and repulsion is used to predict flow measurements in tests involving extremely low freestream temperatures. For the two cases considered, a Mach 26 nitrogen shock and a Mach 20 nitrogen flow over a flat place, only rotational excitation is deemed important, and appropriate modifications for the Borgnakke-Larsen procedure are developed. In general, for the cases considered, the present model performed better than the variable hard sphere model.

    2008-06-01

    Full Text Available Abstract Background All patients who undergo surgery for colon cancer are followed up according to the guidelines of the Norwegian Gastrointestinal Cancer Group (NGICG. These guidelines state that the aims of follow-up after surgery are to perform quality assessment, provide support and improve survival. In Norway, most of these patients are followed up in a hospital setting. We describe a multi-centre randomized controlled trial to test whether these patients can be followed up by their general practitioner (GP without altering quality of life, cost effectiveness and/or the incidence of serious clinical events. Methods and Design Patients undergoing surgery for colon cancer with histological grade Dukes's Stage A, B or C and below 75 years of age are eligible for inclusion. They will be randomized after surgery to follow-up at the surgical outpatient clinic (control group or follow-up by the district GP (intervention group. Both study arms comply with the national NGICG guidelines. The primary endpoints will be quality of life (QoL (measured by the EORTC QLQ C-30 and the EQ-5D instruments, serious clinical events (SCEs, and costs. The follow-up period will be two years after surgery, and quality of life will be measured every three months. SCEs and costs will be estimated prospectively. The sample size was 170 patients. Discussion There is an ongoing debate on the best method of follow-up for patients with CRC. Due to a wide range of follow-up programmes and paucity of randomized trials, it is impossible to draw conclusions about the best combination and frequency of clinic (or family practice visits, blood tests, endoscopic procedures and radiological examinations that maximize the clinical outcome, quality of life and costs. Most studies on follow-up of CRC patients have been performed in a hospital outpatient setting. We hypothesize that postoperative follow-up of colon cancer patients (according to national guidelines by GPs will not have

    2015-12-01

    Effective treatment of orthopedic injuries requires a multidisciplinary team, including physical and occupational therapists, athletic trainers, massage therapists, and acupuncturists. Orthopedic surgeons commonly encounter these practitioners but may not be familiar with the training, credentialing, and most importantly, the appropriate use of members of this team. There are general similarities in practice locations as well as types of symptoms addressed by the providers discussed, which include the treatment of physical pain, evaluation and treatment of physical impairment, and some facilitation of adaptation to the limitations caused by injuries. Across the 5 types of providers discussed there are widely varying training and licensing requirements, specializations, and continuing education requirements to maintain licensure. This article provides a focused review of these members of the multidisciplinary team and highlights the current American Academy of Orthopaedic Surgeons recommendations for the use of occupational and physical therapists for orthopedic conditions, including hip fractures, total hip arthroplasty, and anterior cruciate ligament reconstruction.

    2015-02-01

    Outcome studies of immediate implant-based breast reconstruction have focused largely on patient factors, whereas the relative impact of the surgeon as a contributing variable is not known. As the procedure requires collaboration of both a surgical oncologist and a plastic surgeon, the effect of the surgeon team interaction can have a significant impact on outcome. This study examines outcomes in implant-based breast reconstruction and the association with patient characteristics, surgeon, and surgeon team familiarity. A retrospective review of 3142 consecutive implant-based breast reconstruction mastectomy procedures at one institution was performed. Infection and skin necrosis rates were measured. Predictors of outcomes were identified by unadjusted logistic regression followed by multivariate logistic regression. Surgeon teams were grouped according to number of cases performed together. Patient characteristics remain the most important predictors for outcomes in implant-based breast reconstruction, with odds ratios above those of surgeon variables. The authors observed significant differences in the rate of skin necrosis between surgical oncologists with an approximately two-fold difference between surgeons with the highest and lowest rates. Surgeon teams that worked together on fewer than 150 procedures had higher rates of infection. Patient characteristics are the most important predictors for surgical outcomes in implant-based breast reconstruction, but surgeons and surgeon teams are also important variables. High-volume surgeon teams achieve lower rates of infection. This study highlights the need to examine modifiable risk factors associated with optimum implant-based breast reconstruction outcomes, which include patient and provider characteristics and the surgical team treating the patient.

    2012-01-01

    We construct the manifold describing the family of plane monochromatic light waves with all directions, polarizations, phases and intensities. A smooth description of polarization, valid over the entire sphere S^2 of directions, is given through the construction of an orthogonal basis pair of complex polarization vectors for each direction; any light beam is then uniquely and smoothly specified by giving its direction and two complex amplitudes. This implies that the space of all light beams is the six dimensional manifold S^2 X C^2, the Cartesian product of a sphere and a two dimensional complex vector space. A Hopf map (i.e mapping the two complex amplitudes to the Stokes parameters) then leads to the four dimensional manifold S^2 X S^2 which describes beams with all directions and polarization states. This product of two spheres can be viewed as an ordered pair of two points on a single sphere, in contrast to earlier work in which the same system was represented using Majorana's mapping of the states of a ...

    2008-02-01

    Whether new to private practice or a seasoned practitioner, an oral and maxillofacial surgeon (OMS) needs to understand how to handle complicated and often stressful negotiations of contracts for which he or she usually is untrained. This article is designed to give a general understanding of certain common contractual language. It is not comprehensive in scope, but it attempts to cover contracts that are most often seen by an OMS in practice. It is a general discussion of common legal concepts that could face an OMS, but it is not, nor is it intended to be, legal advice.

  7. Recent and past musical activity predicts cognitive aging variability: direct comparison with general lifestyle activities.

    Studies evaluating the impact of modifiable lifestyle factors on cognition offer potential insights into sources of cognitive aging variability. Recently, we reported an association between extent of musical instrumental practice throughout the life span (greater than 10 years) on preserved cognitive functioning in advanced age. These findings raise the question of whether there are training-induced brain changes in musicians that can transfer to non-musical cognitive abilities to allow for compensation of age-related cognitive declines. However, because of the relationship between engagement in general lifestyle activities and preserved cognition, it remains unclear whether these findings are specifically driven by musical training or the types of individuals likely to engage in greater activities in general. The current study controlled for general activity level in evaluating cognition between musicians and nomusicians. Also, the timing of engagement (age of acquisition, past versus recent) was assessed in predictive models of successful cognitive aging. Seventy age and education matched older musicians (>10 years) and non-musicians (ages 59-80) were evaluated on neuropsychological tests and general lifestyle activities. Musicians scored higher on tests of phonemic fluency, verbal working memory, verbal immediate recall, visuospatial judgment, and motor dexterity, but did not differ in other general leisure activities. Partition analyses were conducted on significant cognitive measures to determine aspects of musical training predictive of enhanced cognition. The first partition analysis revealed education best predicted visuospatial functions in musicians, followed by recent musical engagement which offset low education. In the second partition analysis, early age of musical acquisition (memory in musicians, while analyses for other measures were not predictive. Recent and past musical activity, but not general lifestyle activities, predicted variability

    The aim of the study was to evaluate the knowledge, attitude, and practices of dental surgeons in the city of Karachi providing treatment to pediatric patients. A cross-sectional study was conducted to evaluate the knowledge, attitude, and practices of dental surgeons in the city of Karachi providing treatment to pediatric patients. A cluster-sampling technique was used and 200 dental surgeons from six different dental institutions were selected. A self-constructed questionnaire was distributed to the dental surgeons that comprised 20 closed-ended questions. The data was entered and analyzed for frequency and percentages by using Statistical Package for the Social Sciences (SPSS) version 19. The results showed that 76 (38%) dental surgeons took the responsibility of managing pediatric patient when given; 68 (34%) dental surgeons allowed the parents in the clinic; 111 (55.5%) dental surgeons are of the view that colorful and fun environment in dental clinic make the child at ease; 59 (29.5%) always demonstrate the dental procedure to the child to eradicate imaginary fears; 94 (47.0%) dental surgeons preferred the child to be treated in general anesthesia (GA) to avoid difficult behavior of the child; 135 (67.5%) dental surgeons did not show syringe needle or any instrument to the child. All the members of dental profession must be aware of patient perceptions, preferences, and fear to meet patient’s needs. Dental studies should include guidelines and techniques to train the upcoming dentists for excellent practice in pediatric dentistry. How to cite this article Wali A, Siddiqui TM, Khan R, Batool K.

    Full Text Available Background: Heterogeneity of surgical care exists among surgeons regarding the conduct of thyroidectomy and parathyroidectomy.Aim: To identify the current patterns of technical conduct of operation amongst surgeons performing thyroidectomy or parathyroidectomy.Methods: A survey was designed and beta-tested on five surgical oncologists for face validity and usability. The final version of this survey was constructed and disseminated using the professional version of the internet-based survey mechanism Survey Monkey and consisted of two eligibility questions and 22 questions regarding thyroidectomy/parathyroidectomy treatment patterns. The survey was disseminated electronically to American Association of Endocrine Surgeons (AAES and American College of Surgeons (ACS members. Survey results were collected, tabulated and analyzed. Responses among groups were compared using two sample T- tests. Significant responses were subsequently analyzed in generalized linear models to ascertain if significance remained with control of covariates.Results: Of 420 initial web survey visits, 236 (56.2% surveys were completed. The majority of respondents reported being 'fellowship trained', experienced and 'high-volume' surgeons. The most common fellowship trainings were endocrine (46%, oncology (22%, head & neck (13%, or combinations of the three fellowships (14%. Most surgeons reported that they dissect the course of the recurrent laryngeal nerve (RLN without using neuromonitoring. Nearly a third of respondents reported routinely using the Harmonic scalpel during the conduct of the operations. Significant differences emerged regarding operative technique according to residency training type, fellowship training, surgeon volume, and practice setting, but only those associated with residency training type and annual surgeon surgical volume remained significant within generalized linear models.Conclusion: Most surgeons who responded to this survey do not routinely

  16. Surgeons and non-surgeons prefer haptic feedback of instrument vibrations during robotic surgery.

    Koehn, Jacqueline K; Kuchenbecker, Katherine J

    2015-10-01

    Clinical robotic surgery systems do not currently provide haptic feedback because surgical instrument interactions are difficult to measure and display. Our laboratory recently developed a technology that allows surgeons to feel and/or hear the high-frequency vibrations of robotic instruments as they interact with patient tissue and other tools. Until now, this type of feedback had not been carefully evaluated by users. We conducted two human-subject studies to discover whether surgeons and non-surgeons value the addition of vibration feedback from surgical instruments during robotic surgery. In the first experiment, 10 surgeons and 10 non-surgeons (n = 20) used an augmented Intuitive da Vinci Standard robot to repeatedly perform up to four dry-lab tasks both with and without haptic and audio feedback. In the second experiment, 68 surgeons and 26 non-surgeons (n = 94) tested the same robot at a surgical conference: each participant spent approximately 5 min performing one or two tasks. Almost all subjects in both experiments (95 and 98 %, respectively) preferred receiving feedback of tool vibrations, and all subjects in the second experiment thought it would be useful for surgeons to have the option of such feedback. About half of the subjects (50, 60 %) preferred haptic and audio feedback together, and almost all the rest (45, 35 %) preferred haptic feedback alone. Subjects stated that the feedback made them more aware of tool contacts and did not interfere with use of the robot. There were no significant differences between the responses of different subject populations for any questions in either experiment. This study illustrates that both surgeons and non-surgeons prefer instrument vibration feedback during robotic surgery. Some participants found audio feedback useful but most preferred haptic feedback overall. This strong preference for tool vibration feedback indicates that this technology provides valuable tactile information to the surgeon.

  17. Direct calculation of the lattice Green function with arbitrary interactions for general crystals.

    2012-06-01

    Efficient computation of lattice defect geometries such as point defects, dislocations, disconnections, grain boundaries, interfaces, and free surfaces requires accurate coupling of displacements near the defect to the long-range elastic strain. Flexible boundary condition methods embed a defect in infinite harmonic bulk through the lattice Green function. We demonstrate an efficient and accurate calculation of the lattice Green function from the force-constant matrix for general crystals with an arbitrary basis by extending a method for Bravais lattices. New terms appear due to the presence of optical modes and the possible loss of inversion symmetry. By separately treating poles and discontinuities in reciprocal space, numerical accuracy is controlled at all distances. We compute the lattice Green function for a two-dimensional model with broken symmetry to elucidate the role of different coupling terms. The algorithm is generally applicable in two and three dimensions to crystals with arbitrary number of atoms in the unit cell, symmetry, and interactions.

  18. Controlled quantum secure direct communication by entanglement distillation or generalized measurement

    Tan, Xiaoqing; Zhang, Xiaoqian

    2016-05-01

    We propose two controlled quantum secure communication schemes by entanglement distillation or generalized measurement. The sender Alice, the receiver Bob and the controllers David and Cliff take part in the whole schemes. The supervisors David and Cliff can control the information transmitted from Alice to Bob by adjusting the local measurement angles θ _4 and θ _3. Bob can verify his secret information by classical one-way function after communication. The average amount of information is analyzed and compared for these two methods by MATLAB. The generalized measurement is a better scheme. Our schemes are secure against some well-known attacks because classical encryption and decoy states are used to ensure the security of the classical channel and the quantum channel.

    2007-02-01

    The aim of this study was to determine the characteristics of parenteral antimicrobial therapy (PAT) in the general practice setting in Italy, the characteristics of patients and the presence of possible external factors (induced prescriptions). 204 General Practitioners (GPs) enrolled during a one-year period the first ten patients to whom they prescribed a PAT, collecting data about clinical characteristics, compliance, outcome and the therapy prescribed or induced. Results indicate that 1,892 patients received a PAT. The use of PAT was preferred for elderly patients. In 55.2% of cases the site of infection was in the lower respiratory tract, followed by urinary tract (14%) and upper respiratory tract (12%). In 98% of cases the route of administration was intramuscular. The first motivation for PAT was in about 50% of cases the severity of the illness, afterward the prescription induced by a specialist in 16% of cases, and in 9% of cases the failure of oral antibiotic therapy.

    The Eco29k I restriction endonuclease is a Sac II isoschizomer that recognizes the sequence 5'-CCGCGG-3' and is encoded, along with the Eco29k I methylase, in the Escherichia coli strain 29k. We have expressed the Eco29k I restriction-methylation system (RM2) in E. coli strain TG1 to produce the strain AXE688. We have developed a directed molecular evolution (DME) mutagenesis method that uses Eco29k I to restrict incoming parental DNA in transformed cells. Using our DME method, we have demonstrated that our AXE688 strain results in mutated directed molecular evolution libraries with diversity greater than 10(7) from a single transformation and with greater than 90% recombinant clones.

    2007-08-01

    Practice nursing is an integral component of British and New Zealand primary care, but in Australia it remains an emerging specialty. Despite an increased focus on the Australian practice nurse role, there has been limited strategic role development, particularly relating to national health priority areas. This paper reports the third stage of a Project exploring the Australian practice nurse role in the management of cardiovascular disease (CVD). This stage involved a consensus development conference, undertaken to identify strategic, priority recommendations for practice nurse role development. 1. Practice nurses have an important role in developing systems and processes for CVD management; 2. A change in the culture of general practice is necessary to promote acceptance of nurse-led CVD management; 3. Future research needs to evaluate specific models of care, incorporating outcome measures sensitive to nursing interventions; 4. Considerable challenges exist in conducting research in general practice; and 5. Changes in funding models are necessary for widespread practice nurse role development. The shifting of funding models provides evidence to support interdisciplinary practice in Australian general practice. The time is ripe, therefore, to engage in prospective and strategic planning to inform development of the practice nurse role.

    Although numerous leadership development programs (LDPs) exist in health care, no programs have been specifically designed to meet the needs of surgeons. This study aimed to elicit practicing surgeons' motivations and desired goals for leadership training to design an evidence-based LDP in surgery. At a large academic health center, we conducted semistructured interviews with 24 surgical faculty members who voluntarily applied and were selected for participation in a newly created LDP. Transcriptions of the interviews were analyzed using analyst triangulation and thematic coding to extract major themes regarding surgeons' motivations and perceived needs for leadership knowledge and skills. Themes from interview responses were then used to design the program curriculum specifically to meet the leadership needs of surgical faculty. Three major themes emerged regarding surgeons' motivations for seeking leadership training: (1) Recognizing key gaps in their formal preparation for leadership roles; (2) Exhibiting an appetite for personal self-improvement; and (3) Seeking leadership guidance for career advancement. Participants' interviews revealed four specific domains of knowledge and skills that they indicated as desired takeaways from a LDP: (1) leadership and communication; (2) team building; (3) business acumen/finance; and (4) greater understanding of the health care context. Interviews with surgical faculty members identified gaps in prior leadership training and demonstrated concrete motivations and specific goals for participating in a formal leadership program. A LDP that is specifically tailored to address the needs of surgical faculty may benefit surgeons at a personal and institutional level. Copyright © 2016 Elsevier Inc. All rights reserved.

    The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society. © The Author(s) 2015.

    Contemporary way of living accompanied by everday frustrations, a frequent use of medicaments, an easy application of corticosteroids, complexity of an opeation, so as an increased incidence of polytraumas --those are the factors responsible for an increasing rate of stress ulcus. The rate of 54 verified stress ulcus in the period from 1969-1979 in Regional Medical Centre of Banja Luka, at Surgical Department, are very often indicative of this disease. Thirty eight operatively treated patients are indicative of severity of this disease. The authors are reporting their experiences in resolving this disease by method of vagotomy with partial gastrectomy in comparison to simple sutures of acutely developed ulcus in addition to PS vagotomy. Perforation, which has, usually, been bigger than the chronic ulcus, we had in 31 cases. If the reports of the world authors are reliable, perforation occurs in 5% of cases only, therefore it is clear how many such conditions has remained undetected or treated under various other "working" diagnoses: (DIC, consumer coagulopathy, fibrinolysis, etc.". The stress ulcus is the disease which is a danger to any patient at Surgical Department.

    2012-01-01

    Full Text Available Aim: Hernia surgery is the second most common surgical intervention performed by general surgeons following emergent surgeries. Shouldice herniorraphy is a classical surgery which is in the high tension repair group. This technique should be known by every surgeon. Also being an alternative method, it can be a necessity in cases in which tension free methods can not be performed. In the present study we investigated the advantages, disadvantages and complications of the Shouldice herniorraphy and Lichtenstein technique with the review of the technical literature. Material and Method: We compared 75 patients who were diagnosed with inguinal hernia and treated with Lichtenstein herniorraphy with 33 patients who were treated with Shouldice herniorraphy in Samsun Bafra Public Hospital between April 2007 and May 2008. Age, sex, hernia type, anesthesia method, mean hospitalisation length, early and late post operative complications were recorded. Result: Early post operative complications were urinary retention, wound infection and hematoma. The patients under spinal anesthesia with urinary retention were treated with urinary catheterization. Superficial wound infection was treated with drainage and antibiotic threapy. Among late postoperative complications; we observed paresthesia in the thigh in one patient in the Shouldice group and relapse hernia in one patient in the Lichtenstein group. Discussion: We suggest that this surgical technique which should be known by every surgeon should be taught to new surgery attenders as an alternative technique. This technique can be an alternative method and also may be the first choice in patients in whom tension free methods can not be applicated.

    2014-06-01

    Full Text Available INTRODUCTION: Nutrition care refers to nutrition-related advice or counselling provided by health professionals in an attempt to improve the nutrition behaviour of patients. AIM: The aim of this study was to describe the practices of a sample of Australian general practitioners (GPs when providing nutrition care to adult patients. METHODS: Eighteen GPs (13 male, 5 female were observed by fourth-year medical students during their general practice rotation. Each GP was observed for five consultations that included nutrition care, totalling 90 observed consultations. In each consultation, students completed a 31-item nutrition care checklist of nutrition care practices that could feasibly occur in a standard consultation. Each practice was marked with either a ‘yes’ (completed, ‘no’ (did not complete or ‘completed by practice nurse prior to or after the consultation’. RESULTS: Twenty-eight nutrition care practices were observed at least once. The most frequently observed practices were measuring and discussing blood pressure (76.7%; n=69, followed by general questions about current diet (74.4%; n=67. Approximately half of the consultations included a statement of a nutrition-related problem (52.2%; n=47, and the provision of nutrition advice that focused on a nutrient (45.6%; n=41 or food group (52.2%; n=47. Consultations with male GPs, as well as GPs with more than 25 years of experience, were associated with an increased number of nutrition care practices per consultation. DISCUSSION: The GPs performed nutrition care practices in varying frequencies. Further research is required to identify the most effective GP nutrition care practices to improve the nutrition behaviour of patients.

  10. Fine- and hyperfine-structure effects in molecular photoionization: I. General theory and direct photoionization

    Germann, Matthias

    2016-01-01

    We develop a model for predicting fine- and hyperfine intensities in the direct photoionization of molecules based on the separability of electron and nuclear spin states from vibrational-electronic states. Using spherical tensor algebra, we derive highly symmetrized forms of the squared photoionization dipole matrix elements from which which we derive the salient selection and propensity rules for fine- and hyperfine resolved photoionizing transitions. Our theoretical results are validated by the analysis of the fine-structure resolved photoelectron spectrum of O$_2$ (reported by H. Palm and F. Merkt, Phys. Rev. Lett. 81, 1385 (1998)) and are used for predicting hyperfine populations of molecular ions produced by photoionization.

    Hill, Austin; Althausen, Peter L; O'Mara, Timothy J; Bray, Timothy J

    2013-06-01

    The financial realities of providing trauma care to injured patients can make it difficult to produce an accurate assessment of the cumulative value orthopaedic trauma surgeons provide to healthcare and university institutions. As with many political battles in the field of medicine, physicians who have been diligently focused on providing patient care were completely unaware of the impending upheaval around them. Whether orthopaedic trauma surgeons are employed or in some type of partnership with hospitals, too often surgeons find the relationship one-sided. In order to effectively negotiate with hospitals, surgeons must demonstrate the comprehensive value they provide to their respective healthcare institutions and universities. Orthopaedic trauma surgeons make direct and indirect financial contributions to the hospital in addition to educational and community services. The sum total of these valued contributions helps fund non-revenue generating programs, provides marketing opportunities, and improves the regional and national reputation of the healthcare institution. This paper provides a comprehensive review of the value contributed to healthcare institutions by orthopaedic trauma surgeons and will serve as a blueprint for all surgeons to accurately account for and demonstrate their value to hospitals while providing efficient and compassionate care to our patients.

    Nine PWA improved on the trained abstract words; seven PWA also showed generalization to concrete words in the same context-category. The region with the highest node degree in the trained abstract network across PWA was left inferior frontal gyrus pars triangularis (L IFGtri; while the highest node degree in the generalized concrete network was left precentral gyrus. Regions that showed increased connectivity for both training and generalization included L IFGtri, right middle frontal gyrus (MFG, and bilateral angular gyrus. Regions that showed increased connectivity regardless of whether or not treatment was given and whether or not treatment was successful included left MFG and bilateral superior frontal gyrus. Additionally, PWA who generalized showed more left than right hemisphere changes in both abstract and concrete networks; while PWA who improved on the trained abstract words, but did not generalize to concrete words showed more left than right hemisphere changes for the abstract network, but more right than left hemisphere changes for the concrete network. These results suggest that (a direct training and generalization are tapping into similar neural mechanisms, and (b changes in the left hemisphere coincide with better treatment outcomes.

    Waeleh, Nazreen; Majid, Zanariah Abdul

    2014-10-01

    Direct block multistep method is developed for the numerical solution of second order ordinary differential equations (ODEs). This method was designed for computing the solution at four points simultaneously using variable step size. The development of this method based on numerical integration and using interpolation approach which are similar to the Adams method. In order to gain an efficient and reliable numerical approximation, this developed block method is implemented in the predictor corrector mode using simple iteration technique. This method has also been proven as a convergence method under suitable conditions of stability and consistency. Several tested problems are taken into account in the numerical experiments and were compared with the existing method. The results obtained showed that this developed block method managed to produce good results.

    A podcast is an audio program distributed online typically freely available through an RSS feed (essentially an on-demand internet radio show). This medium has grown steadily in listenership and popularity since its inception in the early 2000s, especially thanks to popular distribution platforms such as iTunes, and web-enabled listening devices (i.e. smart phones). In terms of science reporting, many high impact journals now produce podcasts to supplement their publications (e.g. Nature, Science, etc.). However, smaller and/or more specialized journals often can't afford to promote their content via podcasts, thus limiting their authors to rely on traditional media and press releases supplied by their colleges and universities. This is where independent or unaffiliated podcasts can fill an open niche: providing a platform for scientists to discuss their research in their own words aimed at a general audience. Traditional press releases often follow a similar pattern, and many science news outlets essentially report the press releases verbatim with little additional content or reporting from primary sources. Podcasts suffer from no such restrictions, and they can be as long and in-depth as the subject matter necessitates. Furthermore, many news outlets no longer employ dedicated science reporters. Science is covered, if at all, by reporters without specialized scientific knowledge or training. This deficit leads to a much higher potential for science news stories to be incorrectly reported, or misinterpreted by the general public. A podcast allows a lab group or department the opportunity to edit the content for brevity and clarity, affording scientists a better chance of getting their research presented to the public in an accurate and representative way. Finally, podcasts allow the public to hear the voice of the scientist, humanizing the hard work they do, and potentially positively influencing the way the public reacts to science as a discipline.

    Purpose Postictal pulmonary edema (PPE) is almost invariably present in human and animal cases of sudden unexpected death in epilepsy (SUDEP) coming to autopsy. PPE may be a contributing factor in SUDEP. The incidence of postictal PPE is unknown. We retrospectively investigated PPE following generalized tonic clonic seizures (GTCS) in the epilepsy monitoring unit. Methods Chest X-Rays (CXR) following each GTCS were obtained in 24 consecutive patients. Relationship of CXR abnormality to seizure duration, ictal/postictal oxygen desaturation (SpO2), apnea and presence of postictal generalized EEG suppression (PGES) was investigated using logistic regression. Results Eleven of 24 patients had CXR abnormalities following a GTCS. In these 11 patients, 22 CXR were obtained and abnormalities were present in 15 CXR. Abnormalities included PPE in 7 patients, of which 2 also had focal infiltrates. In 4 patients focal infiltrates were present without PPE. There was no significant difference in mean time to CXR (225 min) following GTCS in the abnormal CXR group versus the normal group of patients (196 min). Mean preceding seizure duration was longer (p=0.002) in GTCS with abnormal CXR (259.7 sec) versus GTCS with normal CXR (101.2 sec). Odds-ratio for CXR abnormality was 20.46 (p=0.006) with seizure duration greater than 100 sec versus less than 100 sec. On multivariable analysis, only the seizure duration was a significant predictor of CXR abnormality (p=0.015). Conclusions Radiographic abnormalities are not uncommon following GTCS. The presence of CXR abnormality is significantly associated with the duration of the preceding GTCS. Severe, untreated PPE may be relevant to the pathophysiology of SUDEP. PMID:25844030

    Most studies examining endophytic fungi associated with grasses (Poaceae) have focused on agronomically important species in managed ecosystems or on wild grasses in subtropical, temperate and boreal grasslands. However grasses first arose in tropical forests, where they remain a significant and diverse component of understory and forest-edge communities. To provide a broader context for understanding grass-endophyte associations we characterized fungal endophyte communities inhabiting foliage of 11 species of phylogenetically diverse C(3) grasses in the understory of a lowland tropical forest at Barro Colorado Island, Panama. Our sample included members of early-arising subfamilies of Poaceae that are endemic to forests, as well as more recently arising subfamilies that transitioned to open environments. Isolation on culture media and direct PCR and cloning revealed that these grasses harbor species-rich and phylogenetically diverse communities that lack the endophytic Clavicipitaceae known from diverse woodland and pasture grasses in the temperate zone. Both the incidence and diversity of endophytes was consistent among grass species regardless of subfamily, clade affiliation or ancestral habitat use. Genotype and phylogenetic analyses suggest that these endophytic fungi are predominantly host generalists, shared not only among distinctive lineages of Poaceae but also with non-grass plants at the same site.

    Utilization of social media both in the private and professional arenas has grown rapidly in the last decade. The rise of social media use within health care can be viewed as the Internet-based corollary of the patient-centered care movement, in which patient perspectives and values are central to the delivery of quality care. For orthopedic surgeons and their practices, general-purpose online social networks, such as Facebook and Twitter, are convenient platforms for marketing, providing patient education and generating referrals. Virtual health communities are used less frequently by orthopedic surgeons but provide forums for patient engagement and active surgeon-to-patient communication via blogs and ask-the-doctor platforms. This commentary reviews the current state of social media use in orthopedic practice, with particular emphasis on managing the extension of the surgeon-patient relationship online, including the unique practice risks social media poses, such as privacy concerns, potential liability, and time consumption.

    Haptic feedback is drastically reduced in laparoscopic surgery compared to open surgery. Introducing enhanced haptic feedback in laparoscopic instruments might well improve surgical safety and efficiency. In the design process of a laparoscopic grasper with enhanced haptic feedback, handle design should be addressed to strive for optimal usability and comfort. Additionally, the surgeons' perspective on the potential benefits of haptic feedback should be assessed to ascertain the clinical interest of enhanced haptic feedback. A questionnaire was designed to determine surgeons' use and preferences for laparoscopic instruments and expectations about enhanced haptic feedback. Surgeons were also asked whether they experience physical complaints related to laparoscopic instruments. The questionnaire was distributed to a group of laparoscopic surgeons based in Europe. From the 279 contacted subjects, 98 completed the questionnaire (response rate 35 %). Of all respondents, 77 % reported physical complaints directly attributable to the use of laparoscopic instruments. No evident similarity in the main preference for graspers was found, either with or without haptic feedback. According to respondents, the added value of haptic feedback could be of particular use in feeling differences in tissue consistencies, feeling the applied pressure, locating a tumor or enlarged lymph node, feeling arterial pulse, and limiting strain in the surgeon's hand. This study stresses that the high prevalence of physical complaints directly related to laparoscopic instruments among laparoscopic surgeons is still relevant. Furthermore, the potential benefits of enhanced haptic feedback in laparoscopic surgery are recognized by laparoscopic specialists. Therefore, haptic feedback is considered an unmet need in laparoscopy.

    Facebook is the leading online media platform used by plastic surgeons. This study examined Facebook use among plastic surgeons and its perceived impact. A survey on Facebook use was distributed to two groups of plastic surgeons: 500 with professional Facebook pages and 500 without Facebook pages. Responses were stripped of identifying information and analyzed for statistical significance (p exposure (67 percent). Many surgeons (15 to 36 percent) did not follow the direct impact of Facebook on their practices. Some reported that Facebook was responsible for only one to 50 professional Web site hits and less than 5 percent of their new patient referrals in the past year. Estimated conversion-to-surgery rates were highly variable for Facebook users and nonusers. Most Facebook nonusers (67 percent) expected a "neutral" impact, expressing more concerns about unsolicited advertising (51 percent) and wasting time (47 percent). Plastic surgeons tend to perceive Facebook's impact on their practices as positive, but most do not track its direct effects on professional Web site hits, new referrals, or conversion-to-surgery rates. Plastic surgeons using Facebook are encouraged to monitor these parameters to determine whether its continued use is actually worthwhile.

    The design of general-purpose wearable computers demands particular care for how human perception, cognition, and action work and work together. The authors propose a human body-and-mind centric (egocentric as opposed to device-centric) design framework and present initial findings from deploying...... it in the design of a wearable personal assistant (WPA) for orthopedic surgeons. The result is a Google Glass-based prototype system aimed at facilitating touchless interaction with x-ray images, browsing of electronic patient records (EPR) when on the move, and synchronized ad hoc remote collaboration...

    To test how practice interruptions affect worker productivity, we estimate how temporal breaks affect surgeons' performance of coronary artery bypass grafting (CABG). Examining 188 surgeons who performed 56,315 CABG surgeries in Pennsylvania between 2006 and 2010, we find that a surgeon's additional day away from the operating room raised patients' inpatient mortality by up to 0.067 percentage points (2.4% relative effect) but reduced total hospitalization costs by up to 0.59 percentage points. Among emergent patients treated by high-volume providers, where temporal distance is most plausibly exogenous, an additional day away raised mortality risk by 0.398 percentage points (11.4% relative effect) but reduced cost by up to 1.4 percentage points. This is consistent with the hypothesis that as temporal distance increases, surgeons are less likely to recognize and address life-threatening complications. Our estimates imply additional intraprocedural treatment intensity has a cost per life-year preserved of $7871-18,500, well within conventional cost-effectiveness cutoffs.

  5. Has medical history importance for surgeons?

    Wangensteen, O W

    1975-03-01

    Surgeons will do well to remember that the two most important contributions to the growth and extension of surgery came from two disciplines, not then regarded as the most innovative. Anesthesia came from dentistry, the work primarily of W.T.G. Morton of Boston; prophylactic surgical antisepsis originated with the obstetrician Semmelweis, who developed a scheme of prophylactic chemical antisepsis that still remains the core of surgical antisepsis. In the mid 1880's, largely as a result of the work of Chamberland and others of the Pasteur school, surgeons in France and Germany substituted thermal for chemical antisepsis, whenever applicable. Whereas Lister's influence was tremendous in fostering acceptance of antisepsis by surgeons, by the end of his professorial career he had begun his capitulation to prophylactic antisepsis, which was complete by 1896 to the very practices that Semmelweis had proved the value of almost five decades previously. These were 19th century innovations. The greatest boon to surgery's advance in this century has been control of cellulitic infections through chemotherapeutic agencies, the sulfonamides and antibiotics. The tremendous upsurge of interest in research at the end of World War II brought surgeons to a fuller realization of the significant part they could play in the advance of their discipline. Intimate alignment of surgeons with physiologists of the circulation begot intracardiac surgery, a significant innovation with consequences of tremendous import for greater medicine's advance. Today, surgeons attacking the problem of tissue transplantation are aligning themselves with biochemists, geneticists, immunologists, experimental pathologists, and pharmacologists in their broad approach to the phenomenon of allograft rejection. The great extension of vascular surgery since World War II has made jewelers of surgeons of small tubular structures. The technical phases of these demanding operative procedures have largely been overcome

    The duty of a doctor to take care presumes the person who offers medical advice and treatment to unequivocally possess the skills and knowledge to do so. However, a sense of responsibility cannot be guaranteed in the absence of accountability, which in turn requires a comprehensive medical law system to be in place. Such a system is almost non-existent in Pakistan. Keeping the above in mind, we designed this study to assess the knowledge, attitudes and practices of surgeons regarding malpractice at a tertiary care center in Pakistan. This was an observational, cross-sectional, questionnaire-based study conducted during a three month period from 31st March, 2012 to 30th June, 2012 at Civil Hospital, Karachi. Surgeons who were available during the period of our study and had been working in the hospital for at least 6 months were included. Self-administered questionnaires were distributed after seeking informed, written consent. The specialties included were general surgery, cardiothoracic surgery, neurosurgery, ophthalmology, otolaryngology, plastic surgery, pediatric surgery, orthopedic surgery, oral and maxillofacial surgery and gynecology and obstetrics. The study questionnaire comprised of four sections. The first section was concerned with the demographics of the surgeons. The second section analyzed the knowledge of the respondents regarding professional negligence and malpractice. The third section assessed the attitudes surgeons with regard to malpractice. The last section dealt with the general and specific practices and experiences of surgeons regarding malpractice. Of the 319 surgeons interviewed, 68.7% were oblivious of the complete definition of malpractice. Leaving foreign objects inside the patient (79.6%) was the most commonly agreed upon form of malpractice, whereas failure to break news in entirety (43.9%) was most frequently disagreed. In the event of a medical error, majority (67.7%) were ready to disclose their error to the patient. The most

    Improved surgical outcomes in children have been associated with pediatric surgical specialization, previously defined by surgeon operative volume or fellowship training. The present study evaluates pediatric surgical outcomes through classifying surgeons by degrees of pediatric versus adult operative experience. A cross-sectional study was performed using nationally representative hospital discharge data from 1998 to 2007. Patients under 18 years of age undergoing inpatient operations in neurosurgery, otolaryngology, cardiothoracic, general surgery, orthopedic surgery, and urology were included. An index was created, calculating the proportion of children treated by each surgeon. In-hospital mortality and length of stay were compared by index quartiles. Multivariate analysis was adjusted for patient and hospital characteristics. A total of 119,164 patients were operated on by 13,141 surgeons. Within cardiothoracic surgery, there were 1.78 (p=0.02) and 2.61 (ppediatric specialization respectively with the highest quartile. For general surgery, a 2.15 (p=0.04) increase in odds for mortality was found when comparing surgeons between the lowest and the highest quartiles. Comparing the least to the most specialized surgeons, length of stay increased 1.14 days (p=0.02) for cardiothoracic surgery, 0.58 days (p=0.04) for neurosurgery, 0.23 days (p=0.02) for otolaryngology, and decreased by 1.06 days (psurgery. The present study demonstrates that surgeons caring preferentially for children-as a proportion of their overall practice-generally have improved mortality outcomes in general and cardiothoracic surgery. These data suggest a benefit associated with increased referral of children to pediatric practitioners, but further study is required. Copyright © 2013 Elsevier Inc. All rights reserved.

    Our objective was to evaluate the level of occupational risk, attitude and behaviour of surgeons towards HIV-infected patients. A questionnaire survey of 264 randomly selected surgeons in training or in practice in five different health institutions in southeast Nigeria within a five-month period was carried out. A 94% response rate was obtained with completed questionnaires from 264 surgeons. The respondents included obstetricians and gynaecologists (n = 78), general surgeons (n = 121), orthopaedic surgeons (n = 40), dental surgeons (n = 10), ophthalmologists (n = 6), urologists (n = 5), and ear, nose and throat surgeons (n = 4). Of them, 31% (n = 82) were qualified surgeons in practice, while the remaining 69% (n = 182) were resident surgeons in training. In the past five years, 40.2% (n = 106) and 26% (n = 70) of the respondents reported needle-stick injuries and blood splash, respectively, during surgery. The majority of the victims were resident surgeons, obstetricians and gynaecologists, and orthopaedic surgeons. Level of clinical experience and high patient blood loss are likely to contribute to this observation. In all, 89% (n = 236) were engaged in the risky practice of operating on patients with open wounds in their hand and the wounds were contaminated with blood in 5% of cases. During surgical procedures, all (100%) respondents wore protective apron, 65.2% (n = 172) wore double gloves and 30.3% (n = 80) used protective goggles. The use of double gloves and protective eye wear increased remarkably over the past decade, probably because the fear of occupational transmission of HIV was substantial. In total, 83% (n = 220) of the respondents had some reservations about treating patients infected with HIV, while 13.3% (n = 35) viewed them with fear. The remaining 3.4% (n = 9) had a more positive attitude towards HIV-infected patients. Further, 92% advocated preoperative screening, with special precaution during surgery, if the results are positive. In

    Full Text Available OBJECTIVES: Analysis of discrepancies between patient and surgeon expectations before total hip arthroplasty (THA should enable a better understanding of motives of dissatisfaction about surgery, but this question has been seldom studied. Our objectives were to compare surgeons' and patients' expectations before THA, and to study factors which affected surgeon-patient agreement. METHODS: 132 adults (mean age 62.8+/-13.7 years, 52% men on waiting list for THA in three tertiary care centres and their 16 surgeons were interviewed to assess their expectations using the Hospital for Special Surgery Total Hip Replacement Expectations Survey (range 0-100. Patients' and surgeons' answers were compared, for the total score and for the score of each item. Univariate analyses tested the effect of patients' characteristics on surgeons' and patients' expectations separately, and on surgeon-patient differences. RESULTS: Surgeon and patient expectations' mean scores were high (respectively 90.9+/-11.1 and 90.0+/-11.6 over 100. Surgeons' and patients' expectations showed no systematic difference, but there was little agreement on Bland and Altman graph and correlation coefficient was low. Patients had higher expectations than surgeons for sports. Patients rated their expectations according to trust in physician and mental quality of life, surgeons considered disability. More disabled patients and patients from a low-income professional category were often "more optimistic" than their surgeons. CONCLUSION: Surgeons and patients often do not agree on what to expect from THA. More disabled patients expect better outcomes than their surgeons.

    The generalized CP transformations can only be consistently defined in the context of $\\Delta(3n^2)$ lepton symmetry if a certain subset of irreducible representations are present in a model. We perform a comprehensive analysis of the possible automorphisms and the corresponding CP transformations of the $\\Delta(3n^2)$ group. It is sufficient to only consider three automorphisms if $n$ is not divisible by 3 while additional eight types of CP transformations could be imposed for the case of $n$ divisible by 3. We study the lepton mixing patterns which can be derived from the $\\Delta(3n^2)$ family symmetry and generalized CP in the semi-direct approach. The PMNS matrix is determined to be the trimaximal pattern for all the possible CP transformations, and it can only take two distinct forms.

    Based on the closed connections among the homogeneous balance (HB) method and Clarkson-Kruskal (CK) method, we study the similarity reductions of the generalized variable coefficients 2D KdV equation. In the meantime it is shown that this leads to a direct reduction in the form of ordinary differential equation under some integrability conditions between the variable coefficients. Two different cases have been discussed, the search for solutions of those ordinary differential equations yielded many exact travelling and solitonic wave solutions in the form of hyperbolic and trigonometric functions under some constraints between the variable coefficients.

    Superplastic forming has been extensively applied to manufacture parts and components with complex shapes or high-precisions. However, superplastic formation is in multi-stress state. In a long time, uniaxial tensile constitutive equation has been directly generalized to deal with multi-stress state. Whether so doing is feasible or not needs to be proved in theory. This paper first summarizes the establishing processes of superplastic tensile and bulging constitutive equation with variable m, and, using the analytical expressions of equivalent stress ? and equivalent strain rateof free bulge based on the fundamentals of continuum medium plastic mechanics, derives the analytical expressions of optimum loading rules for superplastic free bulge. By comparing the quantitative results on typical superplastic alloy ZnAl22, it is shown that one-dimensional tensile constitutive equations cannot be directly generalized to deal with two-dimensional bulging quantitative mechanical problems; only superplastic bulging constitutive equation based on bulging stress state can be used to treat the quantitative mechanical problems of bulge.

    Optimizing recruitment of the next surgical generation is paramount. Unfortunately, many nonsurgeons perceive surgeons' lifestyle as undesirable. It is unknown, however, whether the surgeons-important opinion makers about their profession-are indeed dissatisfied. We analyzed responses to a survey mailed to all surgeons who were certified by the American Board of Surgery in 1988, 1992, 1996, 2000, and 2004. We performed multivariate analyses to study career dissatisfaction and inability to achieve work-life balance, while adjusting for practice characteristics, demographics, and satisfaction with reimbursement. A total of 895 (25.5%) surgeons responded: mean age was 46 years; 80% were men; 88% were married; 86% had children; 45% were general surgeons; 72% were in urban practice; and 83% were in nonuniversity practice. Surgeons worked 64 hours per week; ideally, they would prefer to work 50 hours per week (median). Fifteen percent were dissatisfied with their careers. On multivariate analysis, significant (p career to their own children. On multivariate analysis, significant risk factors were nonuniversity practice (OR 2.5) and dissatisfaction with reimbursement (OR 3.4). In all, 33.5% did not achieve work-life balance. On multivariate analysis, dissatisfaction with reimbursement (OR 3.0) was a significant risk factor. Respondents' lives could be improved by "limiting emergency call" (77%), "diminishing litigation" (92%), and "improving reimbursement" (94%). Most surgeons are satisfied with their careers. Areas in need of improvement, particularly for nonuniversity surgeons, include reimbursement, work hours, and litigation. Strong local and national advocacy may not only improve career satisfaction, but could also render the profession more attractive for those contemplating a surgical career.

    Full Text Available Smartphones have the ability to benefit plastic surgeons in all aspects of patient care and education. With the sheer number of applications available and more being created everyday, it is easy to miss out on apps which could be of great relevance. Moreover, the range of android applications available has not been extensively discussed in the literature. To this end, we have compiled an exhaustive list of android smartphone applications, which we feel can help our day to day functioning. The apps have been extensively reviewed and neatly described along with all their potential uses. In addition, we have made an effort to highlight ′non-medical′ or efficiency apps which can improve departmental functioning. These apps have not been described in prior articles, and their functionality might not be known to all. We believe that the technology savvy plastic surgeon can make maximum use of these apps to his benefit.

    The facial plastic surgeon potentially has a conflict of interest when confronted with the patients requesting surgery, due to the personal gain attainable by agreeing to perform surgery. The aim of this review is to discuss the potential harm the surgeon can inflict by carrying out facial plastic surgery, beyond the standard surgical complications of infection or bleeding. It will discuss the desire for self-improvement and perfection and increase in the prevalence facial plastic surgery. We address the principles of informed consent, beneficence and non-maleficence, as well as justice and equality and how the clinician who undertakes facial plastic surgery is at risk of breaching these principles without due care and diligence.

    Surgeons and nurses sometimes perceive a high workload on the surgical wards, which may influence admission decisions and staffing policy. This study aimed to explore the relative contribution of various patient and care characteristics to the perceived patients' care intensity and whether differences exist in the perception of surgeons and nurses. We invited surgeons and surgical nurses in the Netherlands for a conjoint analysis study through internet and e-mail invitations. They rated 20 virtual clinical scenarios regarding patient care intensity on a 10-point Likert scale. The scenarios described patients with 5 different surgical conditions: cholelithiasis, a colon tumor, a pancreas tumor, critical leg ischemia, and an unstable vertebral fracture. Each scenario presented a mix of 13 different attributes, referring to the patients' condition, physical symptoms, and admission and discharge circumstances. A total of 82 surgeons and 146 surgical nurses completed the questionnaire, resulting in 4560 rated scenarios, 912 per condition. For surgeons, 6 out of the 13 attributes contributed significantly to care intensity: age, polypharmacy, medical diagnosis, complication level, ICU-stay and ASA-classification, but not multidisciplinary care. For nurses, the same six attributes contributed significantly, but also BMI, nutrition status, admission type, patient dependency, anxiety or delirium during hospitalization, and discharge type. Both professionals ranked 'complication level' as having the highest impact. The differences between surgeons and nurses on attributes contributing to care intensity may be explained by differences in professional roles and daily work activities. Surgeons have a medical background, including technical aspects of their work and primary focus on patient curation. However, nurses are focused on direct patient care, i.e., checking vital functions, stimulating self-care and providing woundcare. Surgeons and nurses differ in their perception of

    The Balanced Budget Act of 1997 mandated reductions in physician reimbursement. This reduction in payments could be envisioned to limit expenditures on 2 counts: first, individual fees would be lower, producing inherent savings. Furthermore, reducing fees should depress the incentive to work, thereby generating additional savings from reduced output. A rival point of view holds that lower fees might paradoxically lead to greater spending because surgeons compensate for per-case reductions by performing more cases. If this income-targeting hypothesis is correct, lower per-case fees leads to increased volume. Increased work output has particularly sizable economic effects in fields like orthopedic surgery because the total cost of orthopedic interventions is usually many times larger than the physician's fee (largely owing to the cost of implants). As such, increases in work volume more than negate the potential savings from lower surgeon's fees.This phenomenon was studied in the context of total knee arthroplasty. In the decade spanning 1996 to 2005, inflation-adjusted physician reimbursement decreased by approximately 5% per year, leading to a cumulative drop in reimbursement from $2847 to $1685. Nonetheless, because the number of procedures performed increased from 253,841 to 498,169 and because payments to hospitals far exceeded payments to surgeons, total expenditures for total knee arthroplasty increased dramatically: more than $7.1 billion additional was spent on hospital payments. Continuing to pay surgeons less is apt to continue to cost more. Counter to intuition, the best strategy for controlling overall spending might be higher, not lower, surgical fees.

    Royal Darwin Hospital (RDH) is the only major hospital for the 'Top End' of Northern Territory and Western Australia. As retrieval distances exceed 2600 km, resident generalist surgeons undertake all emergency neurosurgery. Retrospective clinical study from RDH records and review of prospectively collected datasets from RDH Intensive Care Unit and National Critical Care Trauma Response Centre for all emergency neurosurgery patients between 2008 and 2013. Data were obtained from 161 patients with 167 admissions (73% male, 39% indigenous) who underwent 195 procedures (33 per year), including burr hole, craniotomy, cerebral and posterior fossa craniectomy, elevation fracture and ventricular drain. Trauma accounted for 68%, with alcohol as a known factor in 57%. Subdural haematoma (SDH) accounted for 53%. Severity of head injury at presentation correlated with outcome (R(2) = 0.12, P 24 h (P = 0.023) and specific diagnoses of acute SDH (P = 0.006), acute-on-chronic SDH (P = 0.053) and infection (P = 0.052). Indigenous patients were younger (40 versus 55 years, P < 0.001) and more likely to have alcohol as a factor in trauma cases (71% versus 49%, P = 0.027). Time from injury to hospital was high for accidents at a remote location (12.9 versus 1.3 h, P < 0.001); however, Glasgow Outcome Scales (P = 0.13) were no different to accident at metropolitan Darwin. General surgeons at RDH perform a wide range of emergency neurosurgical procedures primarily for trauma. Factors contributing to poor outcomes included remote location of trauma and delay in reaching the hospital. Outcomes at 3 months appear acceptable. © 2015 Royal Australasian College of Surgeons.

  2. Can a Plastic Surgeon be a Department Chairman?….Really?

    Science.gov (United States)

    Neumeister, M W

    2016-04-01

    There is significant responsibility in being a Department of Surgery Chairman within a medical school. The Chairman is appointed by the Dean of Medicine to lead surgery in a path that serves the mission of the school. The Department of Surgery Chairman is charged with facilitating the academic, operational, and programmatic surgical initiatives of the School of Medicine. Traditionally the Chairman of Surgery has been a general surgeon but now our educational and clinical experiences have changed making traditional leadership less intuitive. Plastic surgeons appointed as current Chairman of the Department of Surgery are rare in the United States. Whereas, general surgeons may have less interaction with other surgical sub-specialties today, Plastic surgeons have more interaction crossing all disciplines of surgery. Innovation and creativity that defines our discipline, seems to fit well with Department leadership where strategic planning, vision and curriculum development, and the pursuit of academic and clinical quality remain core essentials to plastic surgery. This article is an editorial of my philosophy as a plastic surgeon leading a Department of Surgery.

  3. Ergonomic assessment of the posture of surgeons performing endoscopic transurethral resections in urology

    2009-10-01

    Full Text Available Abstract Background During transurethral endoscopic prostate and bladder operations the influence of an ergonomic redesign of the arrangement of the operation equipment - including the introduction of a video-assisted resection method ('monitor endoscopy' instead of directly viewing onto the operation area via the endoscope ('direct endoscopy' - was studied with respect to the postures of the surgeons. Methods Postures were analysed on the basis of video recordings of the surgeons performed in the operation theatre during live operations and subsequent visual posture estimation executed by an observer. In particular, head, trunk and arm positions were assigned to posture categories according to a newly developed posture classification schema. 10 urological operations with direct endoscopy and 9 with monitor endoscopy were included. Results Application of direct endoscopy coincides with distinct lateral and sagittal trunk and head inclinations, trunk torsion and strong forearm and upper arm elevations of the surgeons whereas operations with monitor endoscopy were performed with an almost upright head and trunk and hanging arms. The disadvantageous postures observed during direct endoscopy are mainly caused by the necessity to hold the endoscope continuously in close contact with the eye. Conclusion From an ergonomic point of view, application of the video-assisted resection method should be preferred in transurethral endoscopic operations in order to prevent awkward postures of the surgeons and to limit muscular strain and fatigue. Furthermore, the application of the monitor method enables the use of a chair equipped with back support and armrests and benefits the reduction of postural stress.

    the training of military surgeons (specialisation general surgery plus a second sub-specialisation either in visceral surgery or orthopaedics/trauma surgery) has been developed in the Joint Medical Service of the German Bundeswehr. Other relevant skills, such as emergency neurotraumatology, battlefield surgery with integrated oral and craniomaxillofacial surgery, and emergency gynaecology are also integrated into this concept and will be addressed in special courses. On successful completion of this training programme, military surgeons will be officially appointed as "Einsatzchirurg" for a duration of 5 years. After this time, it will be obligatory to renew this "combat ready" status. The buildings and materials in German military medical treatment facilities provide for excellent working conditions. The training programme for military surgeons in its end-2010 version has been designed specifically with data about injury pattern and non-battle diseases as well as the political situation and professional requirements in the civilian sphere in mind.

  5. Mentoring during residency education: a unique challenge for the surgeon?

    Science.gov (United States)

    Pellegrini, Vincent D

    2006-08-01

    A mentor serves as role model, counselor, and advocate for an understudy or protégé. The art and science of mentoring have been investigated most thoroughly in the educational literature, yet there are unique situational and individual considerations in the surgical arena that may warrant special consideration. The general attributes of successful mentors are not foreign to academic surgeons but may require deliberate cultivation to optimize mentorship in the context of academic medicine. Moreover, the stages of productive mentoring may be counter to the learned adaptive behaviors and instinctive personality traits of some accomplished surgeon educators. Indeed, examples of failed mentorship are common in our medical centers and, specifically, in surgical training programs. The behavioral adaptation that supports surgical decision-making under conditions of incomplete data and unusual stress often devalues succession planning and derivation of satisfaction from the success of other members of the team. Accordingly, fostering effective mentoring relationships in academic surgery will require a concerted effort to develop appropriate behaviors conducive to the mentoring process. The personal and professional growth of our students as well as the succession planning for our specialty are dependent upon the successful creation of an environment conducive to mentoring in academic orthopaedics.

  6. John M. T. Finney: distinguished surgeon and Oslerphile

    2016-01-01

    John Finney (1863–1942) was born near Natchez, Mississippi. After receiving his medical degree from Harvard, he interned at Massachusetts General Hospital and then went to Baltimore to become one of the first interns at the new Johns Hopkins Hospital. He met William Osler the day the hospital opened and became a lifelong admirer of “the Chief.” Finney specialized in gastrointestinal surgery and was recognized for his expertise in the field. Osler recommended Finney to a physician colleague, writing, “You could not be in better hands…. Finney has been most successful and his judgment is so good.” Finney served for 33 years under William Halsted at Hopkins. After Halsted's death, Finney was offered the chair of surgery at Johns Hopkins but declined. He was a founder and first president of the American College of Surgeons. He also served as president of the American Surgical Association and the Society of Clinical Surgery. Finney became chief surgical consultant for the Allied Expeditionary Forces in World War I. He was decorated by the United States, France, and Belgium. Finney was a master surgeon and a role model for generations of students and physicians. PMID:26722185

  7. Vascular injuries during gynecological laparoscopy: the vascular surgeon's advice

    Directory of Open Access Journals (Sweden)

    Marcello Barbosa Barros

    Full Text Available CONTEXT: Iatrogenic vascular problems due to laparoscopy are a well recognized problem and lead to significant repercussions. In this context, a ten-year review of cases topic is presented, based on experience gained while heading two important vascular surgery services. CASES: Five patients with vascular injuries during elective laparoscopy are described. These patients presented with seven lesions of iliac vessels. All cases were evaluated immediately and required laparotomy, provisional hemostasis and urgent attendance by a vascular surgeon. Direct suturing was performed in three cases. One aortoiliac bypass and one ilioiliac reversed venous graft were made. Venous lesions were sutured. One case of a point-like perforation of the small bowel was found. There were no deaths and no complications during the postoperative period. DISCUSSION: Important points on this subject are made, and advice is given. There needs to be immediate recognition of the vascular injury, and expert repair by a vascular surgeon is recommended, in order to significantly reduce the degree of complications.

    Due to high noise levels in the voxel kinetics, development of reliable parametric imaging algorithms remains one of most active areas in dynamic brain PET imaging, which in the vast majority of cases involves receptor/transporter studies with reversibly binding tracers. As such, the focus of this work has been to develop a novel direct 4D parametric image reconstruction scheme for such tracers. Based on a relative equilibrium (RE) graphical analysis formulation (Zhou et al 2009b Neuroimage 44 661-70), we developed a closed-form 4D EM algorithm to directly reconstruct distribution volume (DV) parametric images within a plasma input model, as well as DV ratio (DVR) images within a reference tissue model scheme (wherein an initial reconstruction was used to estimate the reference tissue time-activity curves). A particular challenge with the direct 4D EM formulation is that the intercept parameters in graphical (linearized) analysis of reversible tracers (e.g. Logan or RE analysis) are commonly negative (unlike for irreversible tracers, e.g. using Patlak analysis). Subsequently, we focused our attention on the AB-EM algorithm, derived by Byrne (1998, Inverse Problems 14 1455-67) to allow inclusion of prior information about the lower (A) and upper (B) bounds for image values. We then generalized this algorithm to the 4D EM framework, thus allowing negative intercept parameters. Furthermore, our 4D AB-EM algorithm incorporated and emphasized the use of spatially varying lower bounds to achieve enhanced performance. As validation, the means of parameters estimated from 55 human 11C-raclopride dynamic PET studies were used for extensive simulations using a mathematical brain phantom. Images were reconstructed using conventional indirect as well as proposed direct parametric imaging methods. Noise versus bias quantitative measurements were performed in various regions of the brain. Direct 4D EM reconstruction resulted in notable qualitative and quantitative accuracy

    2015-11-01

    Often in geophysical monitoring experiments time-lapse inversion models vary too smoothly with time, owing to the strong imprint of regularization. Several methods have been proposed for focusing the spatiotemporal changes of the model parameters. In this study, we present two generalizations of the minimum support norm, which favour compact time-lapse changes and can be adapted to the specific problem requirements. Inversion results from synthetic direct current resistivity models that mimic developing plumes show that the focusing scheme significantly improves size, shape and magnitude estimates of the time-lapse changes. Inversions of the synthetic data also illustrate that the focused inversion gives robust results and that the focusing settings are easily chosen. Inversions of full-decay time-domain induced polarization (IP) field data from a CO2 monitoring injection experiment show that the focusing scheme performs well for field data and inversions for all four Cole-Cole polarization parameters. Our tests show that the generalized minimum support norms react in an intuitive and predictable way to the norm settings, implying that they can be used in time-lapse experiments for obtaining reliable and robust results.

  10. A ROBUST PHASE-ONLY DIRECT DATA DOMAIN ALGORITHM BASED ON GENERALIZED RAYLEIGH QUOTIENT OPTIMIZATION USING HYBRID GENETIC ALGORITHM

    2007-01-01

    A robust phase-only Direct Data Domain Least Squares (D3LS) algorithm based on generalized Rayleigh quotient optimization using hybrid Genetic Algorithm (GA) is presented in this letter. The optimization efficiency and computational speed are improved via the hybrid GA composed of standard GA and Nelder-Mead simplex algorithms. First, the objective function, with a form of generalized Rayleigh quotient, is derived via the standard D3LS algorithm. It is then taken as a fitness function and the unknown phases of all adaptive weights are taken as decision variables.Then, the nonlinear optimization is performed via the hybrid GA to obtain the optimized solution of phase-only adaptive weights. As a phase-only adaptive algorithm, the proposed algorithm is simpler than conventional algorithms when it comes to hardware implementation. Moreover, it processes only a single snapshot data as opposed to forming sample covariance matrix and operating matrix inversion. Simulation results show that the proposed algorithm has a good signal recovery and interferences nulling performance, which are superior to that of the phase-only D3LS algorithm based on standard GA.

  11. A generalized computationally efficient inverse characterization approach combining direct inversion solution initialization with gradient-based optimization

    2017-03-01

    A computationally efficient gradient-based optimization approach for inverse material characterization from incomplete system response measurements that can utilize a generally applicable parameterization (e.g., finite element-type parameterization) is presented and evaluated. The key to this inverse characterization algorithm is the use of a direct inversion strategy with Gappy proper orthogonal decomposition (POD) response field estimation to initialize the inverse solution estimate prior to gradient-based optimization. Gappy POD is used to estimate the complete (i.e., all components over the entire spatial domain) system response field from incomplete (e.g., partial spatial distribution) measurements obtained from some type of system testing along with some amount of a priori information regarding the potential distribution of the unknown material property. The estimated complete system response is used within a physics-based direct inversion procedure with a finite element-type parameterization to estimate the spatial distribution of the desired unknown material property with minimal computational expense. Then, this estimated spatial distribution of the unknown material property is used to initialize a gradient-based optimization approach, which uses the adjoint method for computationally efficient gradient calculations, to produce the final estimate of the material property distribution. The three-step [(1) Gappy POD, (2) direct inversion, and (3) gradient-based optimization] inverse characterization approach is evaluated through simulated test problems based on the characterization of elastic modulus distributions with localized variations (e.g., inclusions) within simple structures. Overall, this inverse characterization approach is shown to efficiently and consistently provide accurate inverse characterization estimates for material property distributions from incomplete response field measurements. Moreover, the solution procedure is shown to be capable

    The war service of Lilian Violet Cooper, the first female surgeon of the Royal Australasian College of Surgeons, is well recognized. Not so well known however, are the other pioneering female doctors who also undertook work as military surgeons during World War I. At least four of the 14 Australian female doctors that undertook overseas war service during World War I were engaged as surgeons and treated Australian, British and Allied casualties. These women operated in London, in Egypt and on the frontlines of the Macedonian campaign. While none of these other women became Fellows of the Royal Australasian College of Surgeons, their war efforts deserve recognition.

    2012-04-01

    Most general thoracic operations in the United States are performed by general surgeons. Results obtained by those identified as general surgeons are often compared with those identified as thoracic surgeons. We interrogated the American College of Surgeons National Surgical Quality Improvement Project database over a 5-year period to compare outcomes in patients who underwent similar operations by surgeons identified as either thoracic surgeons or general surgeons. We employed propensity-score matching to minimize confounding when estimating the effect of surgeon identity on postoperative outcomes. During the study period, thoracic surgeons performed 3,263 major pulmonary or esophageal operations, and general surgeons performed 15,057 similar operations. Compared with patients operated on by general surgeons, patients operated on by thoracic surgeons had significant excess multivariate comorbidities, including insulin-dependent diabetes mellitus, chronic obstructive pulmonary disease, concurrent pneumonia, congestive heart failure, previous cardiac surgery, dialysis-dependent renal failure, disseminated cancer, prior sepsis, and previous operation within 30 days. Likewise, patients in highest risk categories had operations performed by thoracic surgeons more commonly than by general surgeons. Unadjusted comparisons for mortality and serious morbidity showed significantly worse mortality and pulmonary complications in patients operated on by thoracic surgeons. However, with propensity matching according to surgeon type, thoracic surgeons had significantly fewer serious adverse outcomes compared with general surgeons, and this decreased morbidity occurred in a higher risk cohort. Our results show that patients operated on by thoracic surgeons have higher acuity compared with patients operated on by general surgeons. When patients are matched for comorbidities and serious preoperative risk factors, thoracic surgeons have improved outcomes, especially with regard to

    On April 6, 1917, the United States declared war on Germany and entered what was then called the Great War. Among the first officers sent to Europe were 21 orthopaedic surgeons in the so-called First Goldthwait Unit. Prior to the war, orthopaedics had been a nonoperative "strap-and-buckle" specialty that dealt primarily with infections, congenital abnormalities, and posttraumatic deformity. The Great War changed all of that forever, creating a new surgical specialty with emphasis on acute treatment, prevention of deformity, restoration of function, and rehabilitation.

    2013-05-01

    We surveyed 331 patients undergoing total hip or knee arthroplasty pre-operatively, and patients and surgeons were both surveyed 6 and 12 months post-operatively. We identified variables (demographic factors, operative factors and patient expectations) as possible predictors for discordance in patient-surgeon satisfaction. At 12 months, 94.5% of surgeons and 90.3% of patients recorded satisfaction with the outcome. The discordance between patient and surgeon satisfaction was mainly due to patient dissatisfaction-surgeon satisfaction. In an adjusted analysis, the strongest predictors of discordance in patient-surgeon satisfaction were unmet patient expectations and the presence of complications. Advice to potential joint arthroplasty candidates regarding the decision to proceed with surgery should be informed by patient reported outcomes, rather than the surgeon's opinion of the likelihood of success.

    Advancing surgical technology and decreasing resident learning hours have limited exposure to perioperative training, necessitating more effective and efficient perioperative teaching by faculty surgeons. Participation in collaborative efforts and process improvement can change behaviors and enhance teaching. To promote deliberate teaching of residents, change resident perception of their teachers, and produce sustainable improvements by objectively measuring surgeons' perioperative teaching performance. This 3-phase observational study of surgeons' perioperative teaching behaviors included university-based surgeons, general surgery residents, and preclinical student observers and involved elective cases at a 600+ bed tertiary hospital. Initially, we measured teaching behaviors by surgeons unaware of study objectives, provided aggregate and confidential individual feedback, and developed standardized preoperative briefings and postoperative debriefings. Phase 2 applied a deliberate teaching model and reinforced behaviors with continuous process improvement efforts (Plan, Do, Check, Act) and repeat observations. Phase 3 used resident prompts to enhance teaching behaviors and demonstrate sustainability. Resident surveys conducted 3 times assessed perceptions of deliberate guidance by faculty when compared with national benchmarks. Introduction of deliberate faculty preprocedural focusing and postprocedural reinforcement to facilitate resident learning. More frequent and complete perioperative teaching by faculty and the perception of enhanced teaching by residents. Faculty more commonly and more completely performed the 10-step preoperative briefings and postoperative debriefings (P teaching styles significantly improved and residents' survey-reported assessments of faculty teaching improved over national data for describing procedural steps (P = .02) and requests for resident self-evaluation (P = .006).

    Purpose: Population-based studies suggest underuse of radiation therapy, especially after mastectomy. Because radiation oncology is a referral-based specialty, knowledge and attitudes of upstream providers, specifically surgeons, may influence patients' decisions regarding radiation, including whether it is even considered. Therefore, we sought to evaluate surgeons' knowledge of pertinent risk information, their patterns of referral, and the correlates of surgeon knowledge and referral in specific breast cancer scenarios. Methods and Materials: We surveyed a national sample of 750 surgeons, with a 67% response rate. We analyzed responses from those who had seen at least 1 breast cancer patient in the past year (n=403), using logistic regression models to identify correlates of knowledge and appropriate referral. Results: Overall, 87% of respondents were general surgeons, and 64% saw >10 breast cancer patients in the previous year. In a scenario involving a 45-year-old undergoing lumpectomy, only 45% correctly estimated the risk of locoregional recurrence without radiation therapy, but 97% would refer to radiation oncology. In a patient with 2 of 20 nodes involved after mastectomy, 30% would neither refer to radiation oncology nor provide accurate information to make radiation decisions. In a patient with 4 of 20 nodes involved after mastectomy, 9% would not refer to radiation oncology. Fewer than half knew that the Oxford meta-analysis revealed a survival benefit from radiation therapy after lumpectomy (45%) or mastectomy (32%). Only 16% passed a 7-item knowledge test; female and more-experienced surgeons were more likely to pass. Factors significantly associated with appropriate referral to radiation oncology included breast cancer volume, tumor board participation, and knowledge. Conclusions: Many surgeons have inadequate knowledge regarding the role of radiation in breast cancer management, especially after mastectomy. Targeted educational

    Full Text Available BACKGROUND: Efforts to provide a valid picture of surgeons' individual performance evolution should frame their outcomes in relation to what is expected depending on their experience. We derived the learning curve of young thyroidectomy surgeons as a baseline to enable the accurate assessment of their individual outcomes and avoid erroneous conclusions that may derive from more traditional approaches. METHODS: Operative time and postoperative recurrent laryngeal nerve palsy of 2006 patients who underwent a thyroidectomy performed by 19 young surgeons in five academic hospitals were monitored from April 2008 to December 2009. The database was randomly divided into training and testing datasets. The training data served to determine the expected performance curve of surgeons during their career and factors influencing outcome variation using generalized estimating equations (GEEs. To simulate prospective monitoring of individual surgeon outcomes, the testing data were plotted on funnel plots and cumulative sum charts (CUSUM. Performance charting methods were utilized to present outcomes adjusted both for patient case-mix and surgeon experience. RESULTS: Generation of performance curves demonstrated a gradual reduction in operative time from 139 (95% CI, 137 to 141 to 75 (71 to 80 minutes, and from 15.7% (15.1% to 16.3% to 3.3% (3.0% to 3.6% regarding the nerve palsy rate. Charts interpretation revealed that a very young surgeon had better outcomes than expected, whereas a more experienced surgeon appeared to be a poor performer given the number of years that he had already spent in practice. CONCLUSIONS: Not considering the initial learning curve of surgeons exposes them to biased measurement and to misinterpretation in assessing their individual performance for thyroidectomy. The performance chart represents a valuable tool to monitor the outcome of surgeons with the expectation to provide safe and efficient care to patients.

    This study surveyed a group of US and international orthopaedic surgeons to prioritize areas of improvement in primary total knee arthroplasty (TKA). Specifically, we assessed surgeon responses regarding the top five areas of TKA needing improvement; which were stratified by: a) US surgeons, b) international surgeons, c) US surgeons' implant-brand-loyalty, and d) surgeons' years of experience and case volume. Four hundred and eighteen surgeons who were board-certified, in practice for at least two years, spent 60% of their time in clinical practice, and performed a minimum of 25 lower extremity joint arthroplasties per year were surveyed. They chose the top five areas (among 17) needing improvement for TKA. Results were stratified by surgeons' location (US and international), implant-brand-loyalty, years of experience, and case volume. Functional outcomes was the top identified area for improvement (US 63% and international 71%), followed by brand loyalty (Company I 68%, other brand 59%, and multi-brand/no loyalty 66%), years of experience (early-career 64%, mid-career 63%, and late-career 75%) and case volume (low-volume 69%, mid-volume 60%, and high-volume 71%). Following this was costs for US surgeons (47%) and implant survivorship for international surgeons (57%). While costs were the next highest area for specific Company-loyal surgeons (57%), implant survivorship was the next highest area for the other two cohorts. Implant survivorship was the second most important area of improvement regardless of years of experience and for low- and mid-volume surgeons. Surgeons identified functional outcomes as the most important area needing improvement. Cost of implants was more important for American as compared to international surgeons.

  1. Congenital Ulnar Drift in a Surgeon

    2015-01-01

    Full Text Available Windblown hand is a term used in many instances to describe ulnar deviations of the fingers with or without other malformations. In 1994 Wood reviewed all of the descriptions of cases of windblown hand and pointed out how many variants of congenital ulnar drift there are, suggesting that the many variations seen may all belong to a larger type of arthrogryposis. While the most common cause of ulnar deviation of the fingers is rheumatoid arthritis, it can also be caused by other conditions such as windblown hand or Jaccoud’s arthropathy. While most hand surgeons are familiar with presentations of congenital ulnar drift, few of them are knowledgeable about Jaccoud’s arthropathy as this is usually discussed within medical communities such as Rheumatology. We present a case of a surgeon who has had noticeable ulnar deviation of the digits at the level of the metacarpophalangeal joint since his early 20s. We propose that the current case is a demonstration of a type of windblown hand that has some hereditary component but is not immediately obvious at birth and presents physically more like Jaccoud’s arthropathy than traditional windblown hand.

    In this article, I will outline the origin of cardiothoracic surgical (CTS) training at Indiana University (IU) and its evolution to the present. I will describe my educational background, surgical training in this specialty, and my role as an educator of CT surgeons. I will describe our faculty and the structure of the CTS residency. Finally, I will describe a newly adopted smart phone "App" called SIMPL, which allows the resident and faculty to quickly (50% of the most critical aspects of each surgical procedure, the resident's performance during the critical portion of the operation from poor to excellent, and the degree of difficulty of the operation from simple to complex. The attending surgeon and the resident data are then forwarded to the SIMPL database where the SIMPL software aggregates data for each resident and procedure producing a report at the end of the rotation of the resident's performance relative to his peers. This additional evaluation process will better ensure that our CTS residents are "practice ready" when they complete their training.

  3. Denis Browne: maverick or master surgeon?

    The current generation of surgeons may remember Denis Browne only as an inventor of surgical instruments which few people use, an innovator of procedures condemned as inadequate, and a personality bristling with controversy: a maverick indeed. And yet this assessment belies his influence as the founder of modern paediatric surgery in the development of British surgery. Further, his innovative operations in a range of paediatric lesions were revolutionary in the context of the time. Browne was born in 1892 and educated in Australia, although his whole surgical career was in England. He had a remarkable family background; unique Australian experiences in childhood, when he commenced to display independence and individuality of spirit, through University, where he gained 'Blues' in tennis and shooting, to war, where he served in Gallipoli and France; and to controversies that surrounded him in his battle to establish paediatric surgery as a legitimate surgical discipline. He certainly had a prickly personality and a particular venom reserved for orthopaedic surgeons and anatomists, but his achievements may have been possible only by one possessed of such a strong and towering character.

    Achieving a balance between one's career and personal life is a never-ending challenge. As a surgeon, add-on cases and double-booked clinics can lead to long hours at work and make availability for family time unpredictable. It may seem like the threat of interruption because of patient needs always loom. Disruptions to family time extend beyond the long hours spent in surgery and clinics. Inattentiveness at home because of the technology tethers that keep one available for constant questions and patient care issues can also distract from time spent with family. Although the practice of an orthopaedic trauma surgeon can involve unpredictable schedules and patient care issues, there are means of mitigating the chaos that can envelop one's personal life as a result of a chosen career track. Clear priorities and expectations in both personal and professional arenas can improve the work-life balance. Flexible jobs that allow for more time with family do exist. Negotiating for this flexibility and self-assurance in holding fast to personal ideals are important in achieving a successful balance.

    Because of the infrequent application of cardiac assist devices for postcardiotomy heart failure, most published reports include the results of learning curves from multiple surgeons. Between October 1986 and June 2001, a single surgeon used 35 Sarns Centrifugal Pumps as ventricular assist devices in 21 patients with severe hemodynamic compromise after open heart surgery (0.88% incidence). Patients' ages ranged from 39 to 77 (mean, 59.6 years). Three patients required right ventricular assist devices, 4 left ventricular assist devices, and 14 had biventricular assist devices. For all, the indication for application was inability to wean from cardiopulmonary bypass despite multiple inotropes and intraaortic balloon pumping. All were expected to be intraoperative deaths without further mechanical assistance. Patients were assisted from 2 to 434 h (median, 48 h). Fifteen patients (71.4%) were weaned from device(s), and 11 patients (52.4%) were hospital survivors. Actuarial survival in those dismissed from the hospital was 78% at 5 years and 39% at 10 years. Patients facing certain demise after cardiac surgery can be salvaged with temporary centrifugal mechanical assist. Results are competitive with that achieved with more sophisticated devices. Hospital survivors enjoy reasonable longevity.

  6. Influence of patient symptoms and physical findings on general practitioners' treatment of respiratory tract infections: a direct observation study

    Full Text Available Abstract Background The high rate of antibiotic prescriptions general practitioners (GPs make for respiratory tract infections (RTI are often explained by non-medical reasons e.g. an effort to meet patient expectations. Additionally, it is known that GPs to some extent believe in the necessity of antibiotic treatment in patients with assumed bacterial infections and therefore attempt to distinguish between viral and bacterial infections by history taking and physical examination. The influence of patient complaints and physical examination findings on GPs' prescribing behaviour was mostly investigated by indirect methods such as questionnaires. Methods Direct, structured observation during a winter "cough an cold period" in 30 (single handed general practices. All 273 patients with symptoms of RTI (age above 14, median 37 years, 51% female were included. Results The most frequent diagnoses were 'uncomplicated upper RTI/common cold' (43% followed by 'bronchitis' (26%. On average, 1.8 (95%-confidence interval (CI: 1.7–2.0 medicines per patient were prescribed (cough-and-cold preparations in 88% of the patients, antibiotics in 49%. Medical predictors of antibiotic prescribing were pathological findings in physical examination such as coated tonsils (odds ratio (OR 15.4, 95%-CI: 3.6–66.2 and unspecific symptoms like fatigue (OR 3.1, 95%-CI 1.4–6.7, fever (OR 2.2, 95%-CI: 1.1–4.5 and yellow sputum (OR 2.1, 95%-CI: 1.1–4.1. Analysed predictors explained 70% of the variance of antibiotic prescribing (R2 = 0,696. Efforts to reduce antibiotic prescribing, e.g. recommendations for self-medication, counselling on home remedies or delayed antibiotic prescribing were rare. Conclusions Patient complaints and pathological results in physical examination were strong predictors of antibiotic prescribing. Efforts to reduce antibiotic prescribing should account for GPs' beliefs in those (non evidence based predictors. The method of direct observation was

    The direct radiative forcing (DRF) of sulfate aerosols depends highly on the atmospheric sulfate loading and the meteorology,both of which undergo strong regional and seasonal variations.Because the optical properties of sulfate aerosols are also sensitive to atmospheric relative humidity,in this study we first examine the scheme for optical properties that considers hydroscopic growth.Next,we investigate the seasonal and regional distributions of sulfate DRF using the sulfate loading simulated from NCAR CAM-Chem together with the meteorology modeled from a spectral atmospheric general circulation model (AGCM) developed by LASG-IAP.The global annual-mean sulfate loading of 3.44 mg m -2 is calculated to yield the DRF of -1.03and -0.57 W m-2 for clear-sky and all-sky conditions,respectively.However,much larger values occur on regional bases.For example,the maximum all-sky sulfate DRF over Europe,East Asia,and North America can be up to -4.0 W m-2.The strongest all-sky sulfate DRF occurs in the Northern Hemispheric July,with a hemispheric average of -1.26 W m-2.The study results also indicate that the regional DRF are strongly affected by cloud and relative humidity,which vary considerably among the regions during different seasons.This certainly raises the issue that the biases in model-simulated regional meteorology can introduce biases into the sulfate DRF.Hence,the model processes associated with atmospheric humidity and cloud physics should be modified in great depth to improve the simulations of the LASG-IAP AGCM and to reduce the uncertainty of sulfate direct effects on global and regional climate in these simulations.

    Social media has changed the way plastic surgeons interact with their colleagues, patients, and friends. Social media is a rapidly changing phenomenon that it is critical to plastic surgeons and their practice. Plastic surgery can be marketed directly to consumers and therefore social media can provide a valuable platform to interact with potential patients and to define a surgeon's expertise and practice online. Social media impacts search engine optimization algorithms, increasing web traffic to a surgeon's site, and it can affect patients' perceptions of the practice and surgeon. Social media is a powerful tool, but it should be harnessed wisely to avoid potential pitfalls. This article provides an overview of social media, an outline of resources for surgeons to use, and some tips and tricks for new users. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    The accuracy of risk adjustment is important in developing surgeon profiles. As surgeon profiles are obtained from observational, nonrandomized data, we hypothesized that selection bias exists in how patients are matched with surgeons and that this bias might influence surgeon profiles. We used the Society of Thoracic Surgeons risk model to calculate observed to expected (O/E) mortality ratios for each of six cardiac surgeons at a single institution. Propensity scores evaluated selection bias that might influence development of risk-adjusted mortality profiles. Six surgeons (four high and two low O/E ratios) performed 2298 coronary artery bypass grafting (CABG) operations over 4 years. Multivariate predictors of operative mortality included preoperative shock, advanced age, and renal dysfunction, but not the surgeon performing CABG. When patients were stratified into quartiles based on the propensity score for operative death, 83% of operative deaths (50 of 60) were in the highest risk quartile. There were significant differences in the number of high-risk patients operated upon by each surgeon. One surgeon had significantly more patients in the highest risk quartile and two surgeons had significantly less patients in the highest risk quartile (p < 0.05 by chi-square). Our results show that high-risk patients are preferentially shunted to certain surgeons, and away from others, for unexplained (and unmeasured) reasons. Subtle unmeasured factors undoubtedly influence how cardiac surgery patients are matched with surgeons. Problems may arise when applying national database benchmarks to local situations because of this unmeasured selection bias. PMID:23204823

    2015-01-01

    Iterative reconstruction algorithms for computed tomography (CT) through total variation regularization based on piecewise constant assumption can produce accurate, robust, and stable results. Nonetheless, this approach is often subject to staircase artefacts and the loss of fine details. To overcome these shortcomings, we introduce a family of novel image regularization penalties called total generalized variation (TGV) for the effective production of high-quality images from incomplete or noisy projection data for 3D reconstruction. We propose a new, fast alternating direction minimization algorithm to solve CT image reconstruction problems through TGV regularization. Based on the theory of sparse-view image reconstruction and the framework of augmented Lagrange function method, the TGV regularization term has been introduced in the computed tomography and is transformed into three independent variables of the optimization problem by introducing auxiliary variables. This new algorithm applies a local linearization and proximity technique to make the FFT-based calculation of the analytical solutions in the frequency domain feasible, thereby significantly reducing the complexity of the algorithm. Experiments with various 3D datasets corresponding to incomplete projection data demonstrate the advantage of our proposed algorithm in terms of preserving fine details and overcoming the staircase effect. The computation cost also suggests that the proposed algorithm is applicable to and is effective for CBCT imaging. Theoretical and technical optimization should be investigated carefully in terms of both computation efficiency and high resolution of this algorithm in application-oriented research.

    Cosmetic, aesthetic and cutaneous surgical procedures require qualified specialists trained in the various procedures and competent to handle complications. However, it also requires huge investments in terms of infrastructure, trained staff and equipment. To be viable advertising is essential to any establishment which provides cosmetic and aesthetic procedures. Business men with deep pockets establish beauty chains which also provide these services and advertise heavily to sway public opinion in their favour. However, these saloons and spas lack basic medical facilities in terms of staff or equipment to handle any complication or medical emergency. To have a level playing field ethical advertising should be permitted to qualified aesthetic surgeons as is permitted in the US and UK by their respective organisations. PMID:28529421

  12. Mapping a surgeon's becoming with Deleuze.

    2015-12-01

    The process of 'becoming' shapes professionals' capability, confidence and identity. In contrast to notions of rugged individuals who achieve definitive status as experts, 'becoming' is a continuous emergent condition. It is often a process of struggle, and is always interminably linked to its environs and relationships. 'Becoming' is a way of understanding the tensions of everyday practice and knowledge of professionals. In this paper, we explore the notion of 'becoming' from the perspective of surgeons. We suggest that 'becoming', as theorised by Deleuze, offers a more nuanced understanding than is often represented using conventional vocabularies of competence, error, quality and improvement. We develop this conception by drawing from our Deleuze-inspired study of mapping experience in surgery. We argue for Deleuzian mapping as a method to research health professionals' practice and experience, and suggest the utility of this approach as a pedagogical tool for medical education.

    Foreign body oesophagus is one among the common otorhinolaryngology emergencies that we come across. Artificial partial denture impaction in the oesophagus is often an ENT surgeon's nightmare. This study was done in the department of otorhinolaryngology, Government Medical College Kozhikode for a period of 2 years. All patients presented with history of accidental swallowing of partial denture followed by dysphagia. Radiological evaluation was done and subsequently oesophagoscopy and removal of the denture was done. In failed cases exploration and removal of foreign body was required. Complications were found in partial denture with metal wire clasps. It is better to avoid using malfitting dentures with small base, those with metal wire clasps and be cautious of using dentures in alcoholics and unconscious patients.

    In Brazil's sixteenth-century history, very few references are made to health professionals. On the expedition of Edward Fenton, dispatched by the English Crown in 1582 to set up a trading post in Asia, was the famous barber-surgeon and physician John Banister. The naval squadron, diverted from its original route to repeat the feats of Sir Francis Drake, stopped over in Africa, crossed the Atlantic and anchored off the Santa Catarina coast in Brazil. In these waters, the expedition degenerated into piracy and returned unsuccessful to Europe. John Banister is considered the person who liberated English anatomy from mediaeval slavery, shedding upon it the light of the Renaissance. It was the first time that anyone of this importance in the area of health had visited these latitudes.

    This study aimed to investigate treatment protocols and opinions towards direct pulp capping (DPC) amongst New Zealand (NZ) general dental practitioners (GDP) through a Practice Based Research Network (PBRN) study. Mixed-methods approach using qualitative thematic and quantitative analysis. An on-line survey containing Likert scale items and open-ended questions was distributed to GDPs on the Dental Council of New Zealand (DCNZ) register (2012) to collect information on practitioner demographics, treatment protocols, continuing professional development (CPD) and philosophies towards DPC. RESULTs: Two hundred and ten GDPs from North and South Islands providing care in main centres and rural areas engaged with the PBRN and participated in the study. Almost all performed DPC treatment although it was not a common procedure. DPC was perceived as 'successful' or 'very successful' by 95% of respondents, mostly for cases of reversible pulpitis. Most provided DPC for patients of all ages but younger patients were perceived to have the best clinical outcomes. Calcium hydroxide and MTA were the most commonly used materials for DPC. MTA was believed to have the best outcome but cost and handling properties were barriers to its use. The majority of respondents had participated in CPD related to vital pulp therapy and regarded this treatment as conservative and providing time and financial benefits compared with more invasive treatment. Clinicians' timeframes for assessing healing were variable, and combined clinical and radiographic findings were considered most useful. New Zealand dentists perceive DPC as a successful and conservative treatment in selected cases. The findings have provided insights into engagement of NZ dentists in using research to inform everyday clinical practice through a PBRN study.

  16. Surgeon unemployment: would practice sharing be a viable solution?

    2016-04-01

    Surgeon unemployment has become a crisis within Canadian surgery in recent years. Without dedicated governmental workforce planning, ensuring that new residency graduates can find employment will require new models of employment. Practice sharing, whereby a new graduate and a senior surgeon partner to divide their practices, allows the senior surgeon to wind down and the newer surgeon to ramp up. Importantly, this arrangement builds in formal mentoring, which is so important in the early years of starting a surgical practice. Practice sharing may be a solution for the workforce issues currently afflicting new surgical graduates across Canada.

    Several studies have identified an increased risk of suicide among patient populations which a plastic surgeon may have a high risk of encountering: women undergoing breast augmentation, cosmetic surgery patients, and breast cancer patients. No formal guidelines exist to assist a plastic surgeon when faced with such a patient, and not every plastic surgery team has mental health clinicians that are readily accessible for consultation or referral. The goal of this clinical guide is to offer plastic surgeons a set of practical approaches to manage potentially suicidal patients. In addition, the authors review a screening tool, which can assist surgeons when encountering high-risk patients.

    2012-01-01

    Objective: To assess the capability of operating abdominal and orthopaedic surgeons to analyze a set of standardized ECG. Methods: Twenty operating abdominal and orthopaedic surgeons at a university hospital were included. Each participant analyzed a set of five standardized ECG with an answering scheme for eight different items, giving a maximum score of 40. The answers were matched according to specialty and experience of the doctors of less than 5 years, between 5 and 10 years or more than 10 years. The reference standard was set by two independent consultants in cardiology. Results: The mean overall score was 25.25 (63.13%±4.78%) varying between 38 (95%) and 20(50%). Abdominal surgeons performed a mean score of 27.625 (69.06%±9.53%), and orthopaedic surgeons 23.67 points (59.17%±3.69%). The difference between the performance of abdominal and orthopaedic surgeons was not significant (P=0.09). 20/20 surgeons identified ST-elevation and no surgeon accepted the ECG showing acute ST-elevation myocardial infarction as normal. Conclusions: Abdominal and orthopaedic surgeons provided an answering scheme are able to interprete the ECG and identify both the normal and the ECG showing life-threatening pathology. The hypothesis that surgeons were unable to interprete the ECG must be rejected.

    2012-04-01

    Due to increased economic challenges in the management of hospitals head surgeons do not only need excellent surgical expertise but also significant management qualities. The personality of head surgeons should include authenticity, sincerity, fairness and the ability to cooperate. Visionary leadership, strategic thinking and strategic management of the personnel are further prerequisites for success. Besides good abilities in communication head surgeons need knowledge of the operating figures for interpretation. To keep up with the own capabilities time and self-management is essential. A survival as head surgeon is likely if these qualities and abilities exist.

    Since the number of applicants to residencies in general surgery in Argentina seems to be decreasing, we designed this work with the objective of studying the factors considered undesirable by students when choosing surgery as a specialty. Between March and April 2012, one-hundred students were surveyed with a structured questionnaire with true/false binary answers in an observational case-control design. The survey contained 26 statements that made reference to characteristics of surgery as a specialty, or about the personality and lifestyle of surgeons, as they could be perceived by students. As a control group the same survey was applied to 20 surgeons who were in contact with the students and that could represent a role model for them during their rotation in surgery. Comparison between students and surgeons showed no difference in most answers, except in «surgery has poor reimbursement» (OR: 8,9; P=.0001), «there is not enough job demand» (OR: 8,1; P=.015), «surgery restrains intellectual development» (OR: 17,5; P=.014), «surgeons have too many non-scheduled activities» (OR: 9,36; P=.024), «they have a limited patient-physician relationship» (OR: 3,61; P=.009), «they have little time for family» (OR: 4,27; P=.036) and «they are exposed to infectious diseases» (OR: 5,90; P=.007). Women would be as interested as men in working as surgeons; a remarkable fact when considering that the surgical specialties have been predominantly filled by men. The fact that surgeons mostly coincide with the views of students means that role models should be reviewed to promote vocations. Copyright © 2013 AEC. Published by Elsevier Espana.

    2014-09-01

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: is there a difference in cardiothoracic surgery outcomes in terms of morbidity or mortality of patients operated on by a sleep-deprived surgeon compared with those operated by a non-sleep-deprived surgeon? Reported search criteria yielded 77 papers, of which 15 were deemed to represent the best evidence on the topic. Three studies directly related to cardiothoracic surgery and 12 studies related to non-cardiothoracic surgery. Recommendations are based on 18 121 cardiothoracic patients and 214 666 non-cardiothoracic surgical patients. Different definitions of sleep deprivation were used in the studies, either reviewing surgeon's sleeping hours or out-of-hours operating. Surgical outcomes reviewed included: mortality rate, neurological, renal, pulmonary, infectious complications, length of stay, length of intensive care stay, cardiopulmonary bypass times and aortic-cross-clamp times. There were no significant differences in mortality or intraoperative complications in the groups of patients operated on by sleep-deprived versus non-sleep-deprived surgeons in cardiothoracic studies. One study showed a significant increase in the rate of septicaemia in patients operated on by severely sleep-deprived surgeons (3.6%) compared with the moderately sleep-deprived (0.9%) and non-sleep-deprived groups (0.8%) (P = 0.03). In the non-cardiothoracic studies, 7 of the 12 studies demonstrated statistically significant higher reoperation rate in trauma cases (P sleep deprivation in cardiothoracic surgeons on morbidity or mortality. However, overall the non-cardiothoracic studies have demonstrated that operative time and sleep deprivation can have a significant impact on overall morbidity and mortality. It is likely that other confounding factors concomitantly affect outcomes in out-of-hours surgery. © The Author 2014. Published by Oxford University Press on behalf of

    The absence of a best practice treatment standard contributes to clinical variation in medicine. Often in the absence of evidence, a standard of care is developed and treatment protocols are implemented. The purpose of this study was to examine whether the standard of care for the treatment of nondisplaced scaphoid fractures is uniform among orthopedic surgeons. A survey of orthopedic surgeons actively practicing in the US or abroad was conducted to elicit preferred treatment strategies for nondisplaced scaphoid fractures. The surgeons were recruited at orthopedic conferences, clinical visits, and via email. The survey included demographic questions along with a short clinical vignette. The option for fracture management included surgical versus nonsurgical treatment. For those who chose nonsurgical treatment, type/duration of immobilization was recorded. Cost analysis was performed to estimate direct and indirect costs of various treatment options. A total of 494 orthopedic surgeons completed the survey. The preference for surgical treatment was preferred in 13% of respondents. Hand/upper extremity specialists were significantly more likely to operate compared with generalists (p = 0.0002). Surgeons younger than forty-five were nearly twice as likely to choose surgery (p = 0.01). There was no clear consensus on duration of immobilization as 30% of surgeons chose 6 weeks, 33% selected 8 weeks, and 27% opted for 12 weeks. Total cost of surgery was 49% greater than that of nonoperative treatment. With each additional week of immobilization for nonoperative treatment, the total costs of surgical treatment near that of nonoperative treatment. There exist clear trends in how specific demographic groups choose to treat the nondisplaced scaphoid fracture. Whether these trends are the result of generational gaps or additional subspecialty training remains difficult to determine, but there is need to pursue a more consistent approach that benefits the patients and the

    The importance of effective team leadership for achieving surgical excellence is widely accepted, but we understand less about the behaviors that achieve this goal. We studied cardiac surgical teams to identify leadership behaviors that best support surgical teamwork. We observed, surveyed, and interviewed cardiac surgical teams, including 7 surgeons and 116 team members, from September 2013 to April 2015. We documented 1,926 surgeon/team member interactions during 22 cases, coded them by behavior type and valence (ie, positive/negative/neutral), and characterized them by leadership function (conductor, elucidator, delegator, engagement facilitator, tone setter, being human, and safe space maker) to create a novel framework of surgical leadership derived from direct observation. We surveyed nonsurgeon team members about their perceptions of individual surgeon's leadership effectiveness on a 7-point Likert scale and correlated survey measures with individual surgeon profiles created by calculating percentage of behavior types, leader functions, and valence. Surgeon leadership was rated by nonsurgeons from 4.2 to 6.2 (mean, 5.4). Among the 33 types of behaviors observed, most interactions constituted elucidating (24%) and tone setting (20%). Overall, 66% of interactions (range, 43%-84%) were positive and 11% (range, 1%-45%) were negative. The percentage of positive and negative behaviors correlated strongly (r = 0.85 for positive and r = 0.75 for negative, p leadership. Facilitating engagement related most positively (r = 0.80; p = 0.03), and negative forms of elucidating, ie, criticism, related most negatively (r = -0.81; p = 0.03). We identified 7 surgeon leadership functions and related behaviors that impact perceptions of leadership. These observations suggest actionable opportunities to improve team leadership behavior.

    We assessed surgeon and hospital level variation in robot-assisted radical prostatectomy costs and predictors of high and low cost surgery. The study population consisted of a weighted sample of 291,015 men who underwent robot-assisted radical prostatectomy for prostate cancer by 667 surgeons at 197 U.S. hospitals from 2003 to 2013. We evaluated 90-day direct hospital costs (2014 USD) in the Premier Hospital Database. High costs per robot-assisted radical prostatectomy were those above the 90th percentile and low costs were those below the 10th percentile. Mean hospital cost per robot-assisted radical prostatectomy was $11,878 (95% CI $11,804-$11,952). Mean cost was $2,837 (95% CI $2,805-$2,869) in the low cost group vs $25,906 (95% CI $24,702-$25,490) in the high cost group. Nearly a third of the variation in robot-assisted radical prostatectomy cost was attributable to hospital characteristics and more than a fifth was attributable to surgeon characteristics (R-squared 30.43% and 21.25%, respectively). High volume surgeons and hospitals (90th percentile or greater) had decreased odds of high cost surgery (surgeons: OR 0.24, 95% CI 0.11-0.54; hospitals: OR 0.105, 95% CI 0.02-0.46). The performance of robot-assisted radical prostatectomy at a high volume hospital was associated with increased odds of low cost robot-assisted radical prostatectomy (OR 839, 95% CI 122-greater than 999). This study provides insight into the role of surgeons and hospitals in robot-assisted radical prostatectomy costs. Given the substantial variability, identifying and remedying the root cause of outlier costs may yield substantial benefits.

    2017-01-01

    Background and Objective: Hysterectomy is one of the most common surgical procedures women will undergo in their lifetime. Several factors affect surgical outcomes. It has been suggested that high-volume surgeons favorably affect outcomes and hospital cost. The objective is to determine the impact of individual surgeon volume on total hospital costs for hysterectomy. Methods: This is a retrospective cohort of women undergoing hysterectomy for benign indications from 2011 to 2013 at 10 hospitals within the University of Pittsburgh Medical Center System. Cases that included concomitant procedures were excluded. Costs by surgeon volume were analyzed by tertile group and with linear regression. Results: We studied 5,961 hysterectomies performed by 257 surgeons: 41.5% laparoscopic, 27.9% abdominal, 18.3% vaginal, and 12.3% robotic. Surgeons performed 1–542 cases (median = 4, IQR = 1–24). Surgeons were separated into equal tertiles by case volume: low (1–2 cases; median total cost, $4,349.02; 95% confidence interval [CI] [$3,903.54–$4,845.34]), medium (3–15 cases; median total cost, $2,807.90; 95% CI [$2,693.71–$2,926.93]) and high (>15 cases, median total cost $2,935.12, 95% CI [$2,916.31–$2,981.91]). ANOVA analysis showed a significant decrease (P < .001) in cost from low-to-medium– and low-to-high–volume surgeons. Linear regression showed a significant linear relationship (P < .001), with a $1.15 cost reduction per case with each additional hysterectomy. Thus, if a surgeon performed 100 cases, costs were $115 less per case (100 × $1.15), for a total savings of $11,500.00 (100 × $115). Conclusion: Overall, in our models, costs decreased as surgeon volume increased. Low-volume surgeons had significantly higher costs than both medium- and high-volume surgeons.

    The objective of this study was to determine the profile (credentials, training, and type of practice) of female academic general surgeons and factors that influenced their career choice. A survey was sent to female academic surgeons identified through general surgery residency programs and American medical schools. The women had to be Board eligible/certified by the American Board of Surgery or equivalent Board and have an academic appointment in a Department of Surgery. Data were analyzed using the SPSS program. Two hundred seventy women (age range, 32-70 years) completed the survey (98.9% response rate). Fellowships were completed by 82.3 per cent (223/270), most commonly in surgical critical care. There were 134 (50.2%, 134/367) who had two or more Board certificates, most frequently (46%, 61/134) in surgical critical care. Full-time academic appointments were held by 86.7 per cent of women, most as assistant professors, clinical track; only 12.4 per cent were tenured professors. The majority of women described their practice as "general surgery" or "general surgery with emphasis on breast." The most frequent administrative title was "Director." Only three women stated that they were "chair" of the department. The top reason for choosing surgery was "gut feeling," whereas "intellectual challenge" was the reason they pursued academic surgery. When asked "Would you do it again?", 77 per cent responded in the affirmative. We conclude that female academic surgeons are well trained, with slightly more than half having two or more Board certificates; that most female academic surgeons are clinically active assistant or associate professors whose practice is "general surgery," often with an emphasis on breast disease; that true leadership positions remain elusive for women in academic general surgery; and that 77 per cent would choose the same career again.

    The objective of the present study was to explore how women surgeons manage their work-life balance in three environmental and cultural settings. Members of the Japan Association of Women Surgeons (JAWS), the United States of America (US) based Association of Women Surgeons (AWS), and the Women's Chapter of the College of Surgeons of Hong Kong (WCHK) were surveyed. Among 822 women surgeons contacted, 252 responded (response rate 31.8 %; 55.5 % JAWS, 28.2 % AWS, and 25.3 % WCHK). Japanese women surgeons think that work is the number one priority, whereas US and Hong Kong China (HK) respondents think the number one priority is home life. Work satisfaction level was generally high among women surgeons in all countries; however, 19 % of US surgeons are somewhat dissatisfied with their work and 76.1 % think that men are treated more favorably than women at work. Whereas 51.6 % of Japanese women surgeons think that men are treated more favorably than women at home, at the same time they placed more importance on the role of women in the family. More than half of Japanese women surgeons are "uncertain" about their career path in the future, whereas 55.2/87.1 % of US/HK respondents are optimistic. All surgeons recommended expanding support for child rearing or nursing care during work hours, promoting a flexible work schedule and changing some of the older conventional ideas about gender role. It is essential to address women surgeons' concerns to enable them to have a clearer vision and a challenging career, and to be more certain about their personal and professional goals.

    This paper presents a simple and general direct modulation strategy that enables to copy directly modulated waveforms onto output voltages of a multilevel three-phase Diode Clamped Inverter (DCI). A general modelling of this converter is presented. A space vector scheme is developed without using Park transforms. Based on this algorithm, the location of the reference voltage vector is determined and the voltage vectors for the modulation are deduced. Simultaneously, their durations are calculated. The proposed algorithm is general and can be directly applied to a (n+1) levels inverter independently on its topology (Diode Clamped Inverter, Neutral Point Clamped, Flying Capacitor Inverter...). To verify this algorithm, both control algorithms of a 5-level DCI and a 11-level DCI are considered and simulation results are given.

    -US surgeons. Intra-rater reliability for management was substantial in both US and non-US surgeons. The TLISS incorporates generally accepted features of spinal injury assessment into a simple patient evaluation tool. The management recommendation of the treatment algorithm component of the TLISS shows good inter-rater and substantial intra-rater reliability in both non-US and US based spine surgeons. The TLISS may improve communication between health providers and may contribute to more efficient management of thoracolumbar injuries.

    Direct C-H functionalization and arylation of benzyl ethers has been accomplished via photoredox organocatalysis. The productive merger of a thiol catalyst and a commercially available iridium photoredox catalyst in the presence of household light directly affords benzylic arylation products in good to excellent yield. The utility of this methodology is further demonstrated in direct arylation of 2,5-dihydrofuran to form a single regioisomer.

    Whole-body (WB) dynamic PET has recently demonstrated its potential in translating the quantitative benefits of parametric imaging to the clinic. Post-reconstruction standard Patlak (sPatlak) WB graphical analysis utilizes multi-bed multi-pass PET acquisition to produce quantitative WB images of the tracer influx rate K i as a complimentary metric to the semi-quantitative standardized uptake value (SUV). The resulting K i images may suffer from high noise due to the need for short acquisition frames. Meanwhile, a generalized Patlak (gPatlak) WB post-reconstruction method had been suggested to limit K i bias of sPatlak analysis at regions with non-negligible 18F-FDG uptake reversibility; however, gPatlak analysis is non-linear and thus can further amplify noise. In the present study, we implemented, within the open-source software for tomographic image reconstruction platform, a clinically adoptable 4D WB reconstruction framework enabling efficient estimation of sPatlak and gPatlak images directly from dynamic multi-bed PET raw data with substantial noise reduction. Furthermore, we employed the optimization transfer methodology to accelerate 4D expectation-maximization (EM) convergence by nesting the fast image-based estimation of Patlak parameters within each iteration cycle of the slower projection-based estimation of dynamic PET images. The novel gPatlak 4D method was initialized from an optimized set of sPatlak ML-EM iterations to facilitate EM convergence. Initially, realistic simulations were conducted utilizing published 18F-FDG kinetic parameters coupled with the XCAT phantom. Quantitative analyses illustrated enhanced K i target-to-background ratio (TBR) and especially contrast-to-noise ratio (CNR) performance for the 4D versus the indirect methods and static SUV. Furthermore, considerable convergence acceleration was observed for the nested algorithms involving 10-20 sub-iterations. Moreover, systematic reduction in K i % bias and improved TBR were

    Beauty is a mystery that has been with us for ages. Scholars and scientists have investigated its roots and effects, and its presence is ubiquitous. Has the construct of beauty changed over time? Is our sense of beauty learned or innate? What IS beauty, and can we quantify it? A substantial amount of work supports a Darwinian theory of selection, which predicts a survival advantage based on physical attractiveness. However, there is evidence that certain perceptions of beauty change with time. Indeed, the recent globalization of modern society has wrought changes in our perceptions of beauty. Are patients electing cosmetic surgery procuring a survival advantage, or are they bypassing genetics and setting a new standard for beauty? As facial plastic surgeons, we must be poised to respond to this metamorphosis and understand its roots. Although there is some equivocation and debate about this elusive subject, it is our duty to stay abreast of the current dynamic to make sound judgments that are in the best interests of our patients.

    To determine the frequency of different occupational hazards among dental surgeons in Karachi. Cross-sectional survey. Amulticenter study conducted at Ameen Diabetic and Dental Hospital, Dental OPD, Karachi Medical and Dental College, and Abbasi Shaheed Hospital, Karachi, from February to March 2014. Dentists, practicing in different areas of Karachi, were given a self-administered questionnaire. It comprised of a form containing information about the socio-demographic profile of dentists and questionnaires regarding occupational hazards experienced in practice. Atotal of 130 dentists, involved in clinical practice, were randomly selected. There were 45 (35%) males and 85 (65%) females. The average age was 39 ±5.76 years. Out of 130 dentists, 93.8% (122/130) had occupational hazard during practice. Cervical back pain was observed in 81.96% dentists followed by knee / elbow joint pain in 53.27%, eye infection in 44.615%, impaired hearing in 40.98%, psychological stress in 41.80% and material allergy was 12.29%. Various spinal and joint pains, eye infections, impaired hearing, stress and material allergy represented occupational hazard to 93.8% of the surveyed dentists.

    Suicide and interpersonal violence (i.e. victimization and perpetration) represent pressing public health problems, and yet remain mostly addressed as separate topics. To identify the (1) frequency and overlap of suicide and interpersonal violence and (2) characteristics differentiating subgroups of violence-related experiences. A health survey was completed by 2,175 respondents comprised of three groups: college students ( n = 702), adult members of a sexuality special interest organization ( n = 816) and a community adult sample ( n = 657). Latent class analysis was used to identify subgroups characterized by violence experiences; logistic regression was used to identify respondent characteristics differentiating subgroups. Overall rates of violence perpetration were low; perpetration, victimization and self-directed violence all varied by sample. Adults with alternative sexual interests reported high rates of victimization and self-directed violence. Analyses indicated two subgroups: (1) victimization + self-directed violence and (2) self-directed violence only. The victimization + self-directed violence subgroup was characterized by older, White, female and sexual orientation minority persons. The self-directed violence subgroup was characterized by younger, non-White, male and straight counterparts engaging with more sexual partners and more frequent drug use. Findings support the Centers for Disease Control and Prevention (CDC) definition of suicide as self-directed violence. Suicide intervention and prevention should further account for the role of violent victimization by focusing on the joint conceptualization of self-directed and interpersonal violence. Additional prevention implications are discussed.

    A prospective questionnaire. The aim of this study was to evaluate factors that patients consider when selecting a spine surgeon. The rise in consumer-driven health insurance plans has increased the role of patients in provider selection. The purpose of this study is to identify factors that may influence a patient's criteria for selecting a spine surgeon. Two hundred thirty-one patients who sought treatment by one spine surgeon completed an anonymous questionnaire consisting of 26 questions. Four questions regarded demographic information; 16 questions asked respondents to rate the importance of specific criteria regarding spine surgeon selection (scale 1-10, with 10 being the most important); and six questions were multiple-choice regarding patient preferences toward aspects of their surgeon (age, training background, etc.). Patients rated board certification (9.26 ± 1.67), in-network provider status (8.10 ± 3.04), and friendliness/bedside manner (8.01 ± 2.35) highest among factors considered when selecting a spine surgeon. Most patients (92%) reported that 30 minutes or less should pass between check-in and seeing their surgeon during a clinic appointment. Regarding whether their spine surgeon underwent training as a neurosurgeon versus an orthopedic surgeon, 25% reported no preference, 52% preferred neurosurgical training, and 23% preferred orthopedic training. Our findings suggest that board certification and in-network health insurance plans may be most important in patients' criteria for choosing a spine surgeon. Advertisements were rated least important by patients. Patients expressed varying preferences regarding ideal surgeon age, training background, proximity, medical student/resident involvement, and clinic appointment availability. The surgeon from whom patients sought treatment completed an orthopedic surgery residency; hence, it is notable that 52% of patients preferred a spine surgeon with a neurosurgical background.

    In the absence of a defined retirement age, academic surgeons need to develop plans for transition as they approach the end of their academic surgical careers. The development of a plan for late career transition represents an opportunity for departments of surgery across Canada to initiate a constructive process in cooperation with the key stakeholders in the hospital or institution. The goal of the process is to develop an individual plan for each faculty member that is agreeable to the academic surgeon; informs the surgical leadership; and allows the late career surgeon, the hospital, the division and the department to make plans for the future. In this commentary, the literature on the science of aging is reviewed as it pertains to surgeons, and guidelines for late career transition planning are shared. It is hoped that these guidelines will be of some value to academic programs and surgeons across the country as late career transition models are developed and adopted.

    To compare patient's pain and surgeon's comfort during ECCE performed under retrobulbar anesthesia and phacoemulsification under topical anesthesia. 120 patients scheduled for planned routine cataract extraction were divided in 2 groups: group 1-60 eyes, ECCE under retrobulbar anesthesia and group II-60 eyes, phacoemulsification under topical anesthesia. Immediately after operation patients were asked, to answer questions about their feeling during surgery. Simultaneously, the surgeon filled up the questionnaire, concerning patients behavior during the entire procedure. Statistically significant higher level of pain was reported in group I (ECCE). The most painful moment of the procedure was retrobulbar injection. During surgery pain feeling in both groups was similar. Both types of anesthesia provided very good level of surgeon's comfort. The longer operation, the higher level of pain and lower surgeon's comfort were reported in both groups. Patients having ECCE performed under retrobulbar anesthesia reported more pain comparing to phacoemulsification under topical anesthesia. Both anesthesia methods provided high level of surgeon's comfort.

    2010-05-01

    By 1942, Loyal Davis had firmly established himself as a preeminent civilian neurosurgeon. With military operations rapidly escalating, he was recruited to serve in the European Theater of Operations as a consultant to the Surgeon General. Davis brought tremendous experience, insight, and leadership to this position; however, he found the military system in which he was suddenly immersed inefficient and impassive. His requests for even basic equipment became mired in endless bureaucracy even as his communiqués to the Chief Surgeon in the European Theater and to the Surgeon General's staff in Washington seemed to fall short of their intended recipients. Then, when he attempted to vent his frustrations to his academic colleagues, he was nearly court-martialed. Notwithstanding, Davis became the first to formally recognize high-altitude frostbite and also developed protective headgear for airmen, and later in his service, he joined a contingent of senior medical leaders who visited the Soviet Union to study their system of combat casualty care. Subsequent to his service on active duty, Davis returned to his academic practice at Northwestern where he used his position as editor of Surgery, Gynecology, and Obstetrics to advocate for change within the military medical corps. Others like Davis have contributed greatly to the advancement of combat casualty care both during active service and long after their time in uniform. This paper examines the lessons from Davis's experiences as a military neurosurgeon and his continued advocacy for change in the medical corps along with additional recent examples of change effected by former military surgeons. For those currently serving, these lessons illustrate the value of contributing wherever a need is recognized, and for those who have served in the past, they demonstrate the importance of having a continued voice with junior combat surgeons and the military leadership.

    2012-02-01

    Aim The use of a minimally invasive approach to treat appendicitis has yet to be universally accepted. The objective of this study was to examine recent trends in Ireland in the surgical management of acute appendicitis. Method Data were obtained from the Irish Hospital In-Patient Enquiry system for patients discharged with a diagnosis of appendicitis between 1999 and 2007. An anonymous postal survey was sent to all general surgeons of consultant and registrar level in Ireland to assess current attitudes to the use of laparoscopic appendectomy. Results The use of laparoscopic appendectomy increased throughout the study and was the most common approach for appendectomy in 2007. Multivariate analysis revealed age under 50 years (OR = 1.51), female sex (OR = 2.84) and residence in high-density population areas (OR = 4.15) as predictive factors for undergoing laparoscopic appendectomy in the most recent year of the study. While 97% of surgeons reported current use of laparoscopy in patients with acute right iliac fossa pain, in most cases it was selective. Surgeons in university teaching hospitals (42 of 77; 55%) were more likely to report using laparoscopic appendectomy for all cases of appendicitis than those in regional (six of 23; 26%) or general (13 of 53; 25%) hospitals (P = 0.048). Conclusion This study has demonstrated a significant increase in laparoscopic appendectomy, yet a variety of patient and surgeon factors contribute to the choice of procedure. Differences in the perception of benefit of the laparoscopic approach amongst surgeons appears to be an important factor in determining the operative approach for appendectomy.

    Jan Wolff

    Full Text Available INTRODUCTION: Staff time is a relevant resource in the delivery of health care interventions. Its measurement is a prerequisite for unit costing but usually complex. The aim of this study was to analyse the distribution of surgeons' work time among types and places of activities. A second aim was to use these data to calculate costs per unit of output. METHODS: A self-reporting work sampling study was carried out at a department of Urology. All of twelve surgeons involved in clinical care participated in a two-week analysis of their work time. RESULTS: A total of 2,485 data-points were collected, representing about 1,242 hours of work time. Surgeons spent the greater part of their work time in direct patient care, but substantial shares were required for documentation and organisation. Assistants were mainly required at the wards and consultants at the operating theatre and the outpatient unit. Staff costs of surgeons were 32 € and 29 € per patient day at the wards, respectively, 1.30 € per minute at the operating theatre and 32 € per visit at the outpatient unit. CONCLUSION: Results provided a basis for costing of health care interventions at the study site. However, future research should focus on the establishment of standardised terminology in order to increase transferability of results.

    Full Text Available Abstract Background The aim of this study was to explore the ethical challenges in surgery from the surgeons' point of view and their experience of being in ethically difficult situations. Methods Five male and five female surgeons at a university hospital in Norway were interviewed as part of a comprehensive investigation into the narratives of nurses and physicians about being in such situations. The transcribed interview texts were subjected to a phenomenological-hermeneutic interpretation. Results No differences in ethical reasoning between male and female surgeons were found. They reasoned in both action and relational ethical perspectives. Surgeons focused on their relationships with patients and colleagues and their moral self in descriptions of the ethical challenges in their work. Dialogue and personal involvement were important in their relationships with patients. The surgeons emphasized the importance of open dialogue, professional recognition, and an inclusive and accepting environment between colleagues. Conclusion The surgeons are personally challenged by the existential realities of human life in their relationships with patients. They realized that ethical challenges are an inherent part of performing surgery and of life itself, and say that they have to learn to "live with" these challenges in a way that is confirmed both socially and by their inner moral self. This means accepting their personal and professional limitations, being uncertain, being fallible, and being humble. Living with the ethical challenges of surgery seems to contribute to the surgeons' confidence and vulnerability in their professional identity.

    The Human Genome Project was launched in 1989 in an effort to sequence the entire span of human DNA. Although coding sequences are important in identifying mutations, the static order of DNA does not explain how a cell or organism may respond to normal and abnormal biological processes. By examining the mRNA content of a cell, researchers can determine which genes are being activated in response to a stimulus. Traditional methods in molecular biology generally work on a "one gene: one experiment" basis, which means that the throughput is very limited and the "whole picture" of gene function is hard to obtain. To study each of the 60,000 to 80,000 genes in the human genome under each biological circumstance is not practical. Recently, microarrays (also known as gene or DNA chips) have emerged; these allow for the simultaneous determination of expression for thousands of genes and analysis of genome-wide mRNA expression. The purpose of this article is twofold: first, to provide the clinical plastic surgeon with a working knowledge and understanding of the fields of genomics, microarrays, and bioinformatics and second, to present a case to illustrate how these technologies can be applied in the study of wound healing.

    Purpose Comparison of resident surgeon performance efficiencies in femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification. Patients and methods A retrospective cohort study was conducted on consecutive patients undergoing phacoemulsification cataract surgery performed by senior ophthalmology residents under the supervision of 1 attending physician during a 9-month period in a large Veterans Affairs medical center. Medical records were reviewed for demographic information, preoperative nucleus grade, femtosecond laser pretreatment, operative procedure times, total operating room times, and surgical complications. Review of digital video records provided quantitative interval measurements of core steps of the procedures, including completion of incisions, anterior capsulotomy, nucleus removal, cortical removal, and intraocular lens implantation. Results Total room time, operation time, and corneal incision completion time were found to be significantly longer in the femtosecond laser group versus the traditional phacoemulsification group (each Pcataract surgery is generally less efficient when trainees have more experience with traditional phacoemulsification. FLACS was found to have a significant advantage in completion of capsulotomy, but subsequent surgical steps were not shorter or longer. Resident learning curve for the FLACS technology may partially explain the disparities of performance. Educators should be cognizant of a potential for lower procedural efficiency when introducing FLACS into resident training. PMID:28203055

    A study of orthopedic surgeons in rural and regional Southeast Australia to determine attitudes to investigation and management of osteoporosis found they believe follow-up in regard to osteoporosis after MTF is important; responsibility for follow-up diagnosis and management lies with primary health care and current communication systems are poor. The investigation and treatment of osteoporosis after minimal trauma fracture (MTF) is regarded as sub-optimal. There is strong evidence of the benefit of identifying and treating osteoporosis after MTF, and there has been discussion of the possible role that orthopedic surgeons might play in the management of osteoporosis after MTF. The study surveyed orthopedic surgeons in rural and regional Southeast Australia to determine their attitudes to investigation and management of osteoporosis, the role health professionals should play, and the communication and co-ordination of follow-up care. A survey was developed and piloted prior to being posted to 69 orthopedic surgeons asking for their opinions about the general management of osteoporosis, and the roles and responsibilities of health professionals in dealing with osteoporosis following an MTF. Responses were received from 42 participants (60.8%) with the majority of respondents agreeing that it is important to treat osteoporosis following MTF. Less than 15% of respondents felt that it was their responsibility to initiate discussion or treatment or investigation after MTF. No respondent felt that the coordination of osteoporosis care was good and 45% stated it was poor. Communication after discharge is mostly left to the hospital (30%), while 20% stated they did not follow up at all. This study shows that many rural orthopedic surgeons believe that follow-up in regard to osteoporosis after MTF is important, that responsibility for follow-up diagnosis and management of osteoporosis lies with primary health care and the current communication systems are poor.

    Background Literature exists regarding the perioperative role of internists. Internists rely on this literature assuming it meets the needs of surgeons without actually knowing their perspective. We sought to understand why surgeons ask for preoperative consultations and their view on the internist's role in perioperative medicine. Methods Survey of surgeons in Saskatoon, Saskatchewan, Canada regarding an internist's potential role in perioperative care. Results Fifty-nine percent responded. The majority request a preoperative consultation for a difficult case (83%) or specific problem (81%). While almost half feel that a preoperative consultation is to "clear" a patient for surgery, 33% disagree with this statement. The majority believe the internist should discuss risk with the patient. Aspects of the preoperative consultation deemed most important are cardiac medication optimization (93%), cardiac risk stratification (83%), addition of β-blockers (76%), and diabetes management (74%). Conclusion Surgeons perceive the most important roles for the internist as cardiac risk stratification and medication management. Areas of controversy identified amongst the surgeons included who should inform the patient of their operative risk, and whether the internist should follow the patient daily postoperatively. Unclear expectations have the potential to impact on patient safety and informed consent unless acknowledged and acted on by all. We recommend that internists performing perioperative consults communicate directly with the consulting physician to ensure that all parties are in accordance as to each others duties. We also recommend that the teaching of perioperative consults emphasizes the interdisciplinary communication needed to ensure that patient needs are not neglected when one specialty assumes the other will perform a function.

    To estimate the cardiovascular workforce needed by 2030 to meet the needs of our population and to quantify its costs. Our field is changing. The volume of surgery and the nature of the surgery are changing. The nation's population grew from 227,000,000 to 282,000,000 between 1980 and 2000, and by 2030 the population is estimated to be 364,000,000. At the same time, the applications for fellowship in our specialty are decreasing at an alarming rate. The American Board of Thoracic Surgery has certified 4500 cardiothoracic surgeons since 1975, but only 1300 in the last 10 years. The US Department of Health and Human Services predicts only 3620 full-time cardiothoracic surgeons in 2020. Will we have enough cardiovascular and thoracic surgeons? Retrospective examination of the pertinent literature and with a modified Richard Cooper's economic trend analysis, a population algorithm with a ratio of physicians to population of 1.42 per 100,000. Each thoracic surgeon is predicted to practice 30 years from Board certification to retirement. The Balanced Budget Act will not be revised; therefore, we will certify 100 graduates from our programs per year. The assumed salaries will be 50,000 dollars with benefits of 30% and 15,000 dollars of additional Direct Medical Education costs. The population in 2030 will be 364,000,000 with 5169 cardiothoracic surgeons needed at that time. Unfortunately, there will be approximately only 3200 cardiothoracic surgeons in practice with a shortage of approximately 2000. To maintain our current status per 100,000 population from 2011 to 2030, we will have to train 4000 residents. The total person years would be approximately 28,000. The cost for this is more than 2,000,000,000 dollars. The annual cost for this training prorated over 20 years would be more than 110,000,000 dollars. We must train approximately 4000 surgeons, an extra 100 per year, in our specialty to meet the needs of the population by 2030. That will cost approximately 2

    In revealing the conditions for the deduction of input VAT, the essential questions concern the nature of the so-called ‘direct and immediate link’ test and thus also the criteria for the important distinction between direct costs and general costs. The ‘direct and immediate link’ test...... is of general importance to all types of costs, but judged from the case law of the ECJ it has especially materialised itself when it comes to costs related to the acquisition, holding or sales of shares. The purpose of this article is therefore twofold. On the one hand it deals with the difficult question...... of distinguishing between direct and general costs. On the other hand the aim is to describe and analyse the law as it stands regarding the treatment of shares in the EU VAT system, with a special focus on the right to deduct input VAT on costs re-lating to transactions in shares. As a part of this analysis the aim...

  20. There is no direct generalization of positive partial transpose criterion to the three-by-three case

    2016-11-01

    We show that there cannot exist a straightforward generalization of the famous positive partial transpose criterion to three-by-three systems. We call straightforward generalizations that use a finite set of positive maps and arbitrary local rotations of the tested two-partite state. In particular, we show that a family of extreme positive maps discussed in a paper by Ha and Kye [Open Syst. Inf. Dyn. 18, 323-337 (2011)], cannot be replaced by a finite set of witnesses in the task of entanglement detection in three-by-three systems. In a more mathematically elegant parlance, our result says that the convex cone of positive maps of the set of three-dimensional matrices into itself is not finitely generated as a mapping cone.

    Conclusion: In some procedures types a significant part of the variability in operative time is due to the interaction between the surgeon and anesthesiologist. Reviewing operative records should allow identification of efficient/inefficient combinations.

  2. Concussion in Sports: What Do Orthopaedic Surgeons Need to Know?

    2016-12-01

    A concussion is a relatively common sports-related injury that affects athletes of all ages. Although orthopaedic surgeons are not expected to replace sports medicine physicians and neurologists with regard to the management of concussions, orthopaedic surgeons, particularly those who are fellowship-trained in sports medicine, must have a current knowledge base of what a concussion is, how a concussion is diagnosed, and how a concussion should be managed. Orthopaedic surgeons should understand the pathophysiology, assessment, and management of concussion so that they have a basic comprehension of this injury, which is at the forefront of the academic literature and North American media. This understanding will prepare orthopaedic surgeons to work in concert with and assist sports medicine physicians, athletic trainers, and physical therapists in providing comprehensive care for athletes with a concussion.

    2016-05-09

    On July 14, 2015, ProPublica published its Surgeon Scorecard, which displays "Adjusted Complication Rates" for individual, named surgeons for eight surgical procedures performed in hospitals. Public reports of provider performance have the potential to improve the quality of health care that patients receive. A valid performance report can drive quality improvement and usefully inform patients' choices of providers. However, performance reports with poor validity and reliability are potentially damaging to all involved. This article critiques the methods underlying the Scorecard and identifies opportunities for improvement. Until these opportunities are addressed, the authors advise users of the Scorecard-most notably, patients who might be choosing their surgeons-not to consider the Scorecard a valid or reliable predictor of the health outcomes any individual surgeon is likely to provide. The authors hope that this methodological critique will contribute to the development of more-valid and more-reliable performance reports in the future.

    The author gives here some considerations about A. Vesalius through his life and his works as a surgeon. He was the father of the anatomical revolution against Galen but was also an eminent clinician and surgeon. He was immediately able to adapt his surgical practice whenever the promising methodology was identified (see Consilia). The author concludes with a critical analysis of the Chirurgia magna in septem libros digesta attributed to A. Vesalius.

    Declining total joint arthroplasty reimbursement and rising implant prices have led many hospitals to restrict access to newer, more expensive total joint arthroplasty implants. The authors sought to understand arthroplasty surgeons' perspectives on implants regarding innovation, product launch, costs, and cost-containment strategies including surgeon gain-sharing and patient cost-sharing. Members of the International Congress for Joint Reconstruction were surveyed regarding attitudes about implant technology and costs. Descriptive and univariate analyses were performed. A total of 126 surgeons responded from all 5 regions of the United States. Although 76.9% believed new products advance technology in orthopedics, most (66.7%) supported informing patients that new implants lack long-term clinical data and restricting new implants to a small number of investigators prior to widespread market launch. The survey revealed that 66.7% would forgo gain-sharing incentives in exchange for more freedom to choose implants. Further, 76.9% believed that patients should be allowed to pay incremental costs for "premium" implants. Surgeons who believed that premium products advance orthopedic technology were more willing to forgo gain-sharing (P=.040). Surgeons with higher surgical volume (P=.007), those who believed implant companies should be allowed to charge more for new technology (Pinnovation advances the field but support discussing the "unproven" nature of new implants with patients. Many surgeons support alternative payment models permitting surgeons and patients to retain implant selection autonomy. Most respondents prioritized patient beneficence and surgeon autonomy above personal financial gain. [Orthopedics. 201x; xx(x):xx-xx.]. Copyright 2017, SLACK Incorporated.

  6. Surgeons' Emotional Experience of Their Everyday Practice - A Qualitative Study.

    Full Text Available Physicians' emotions affect both patient care and personal well-being. Surgeons appear at particularly high risk, as evidenced by the high rate of burnout and the alarming consequences in both their personal lives and professional behavior. The aim of this qualitative study is to explore the emotional experiences of surgeons and their impact on their surgical practice.27 purposively selected liver and pancreatic surgeons from 10 teaching hospitals (23 men, 4 women participated. Inclusion took place until data saturation was reached. Data were collected through individual interviews and thematically analyzed independently by 3 researchers (a psychologist, a psychiatrist, and a surgeon. 7 themes emerged from the analysis, categorized in 3 main or superordinate themes, which described surgeons' emotional experience before, during, and after surgery. Burdensome emotions are present throughout all 3 periods (and invade life outside the hospital-surgeons' own emotions, their perception of patients' emotions, and their entwinement. The interviewees described the range of emotional situations they face (with patients, families, colleagues, the influence of the institutional framework (time pressure and fatigue, cultural pressure to satisfy the ideal image of a surgeon, as well as the emotions they feel (including especially anxiety, fear, distress, guilt, and accountability.Emotions are ubiquitous in surgeons' experience, and their exposure to stress is chronic rather than acute. Considering emotions only in terms of their relations to operative errors (as previous studies have done is limiting. Although complications are quite rare events, the concern for possible complications is an oppressive experience, regardless of whether or not they actually occur.

  7. How do Orthopedic Surgeons Address Psychological Aspects of Illness?

    2017-01-01

    Full Text Available Background: Orthopaedic surgeons have a pivotal role in transitioning the care of orthopedic patients from a biomedical to a biopsychosocial model. In an effort to foster this transition, we designed a study aimed to determine surgeons’ attitudes and practice of noticing, screening, discussing psychological illness with patients, as well as making referrals to address psychosocial issues in patients in need. Additionally, we asked surgeons to rank order potential barriers to and reasons for referrals to psychosocial treatment.   Methods: Orthopaedic surgeons members of the Science and Variation Group and Ankle Platform (N =350 completed demographics, and a 4-part survey assessing the degree to which surgeons notice, assess, screen and refer for psychological treatments, as well ranked ordered barriers to engaging in these processes. Results: As a group surgeons were neutral to referral for psychological treatment and formal screening of psychological factors, and somewhat likely to notice and discuss psychological factors. Surgeons were more likely to refer for psychological treatment if they engaged in research, or if they reside in South America as opposed to North America. The highest ranked barriers to screening, noticing, discussing and referring for psychological treatment were lack of time, stigma and feeling uncomfortable. Conclusion: Overall surgeons are likely to notice and discuss psychological factors, but less likely to formally screen or refer for psychological treatment. Transition to biopsychosocial models should focus on problem solving these barriers by teaching surgeons communication skills to increase comfort with discussing psychoemotional factors associated with orthopedic problems. The use of empathic communication can be very helpful in normalizing the difficulty of coping with an orthopedic condition, and may facilitate referral.

    Surgeons frequently treat the consequences of self-harm. Self-harm is a common problem and presentations to Irish hospitals are increasing. It increases the risk of suicide and is associated with long term morbidity. Appropriate management can improve the prognosis. Surgeons require a number of skills to appropriately manage patients who self-harm. In this review we outline those skills including diagnosis, communication, capacity and risk assessment.

    Missed injuries sustain an important issue concerning patient safety and quality of care. The purpose of this study is to examine the effect of surgeon commitment to trauma care on missed injuries. We hypothesised that surgeons committed to the trauma service has less missed injuries than surgeons not committed to the trauma service would have. By retrospective analysis of 976 adult patients admitted to the trauma intensive care unit (ICU) at an urban, university-based trauma centre. Missed injuries were compared between two groups; in group 1 the patients were evaluated and treated by the surgeons who were committed to the trauma service and in group 2 the patients were evaluated and treated by surgeons practicing mainly in other specialties. Patients had significantly lower rates of missed major or life-threatening injuries when treated by group 1 surgeons. Logistic regression model revealed significant factors associated with missed major or life-threatening injuries including ISS and groups in which patients were treated by different group surgeons. Physicians will perform better when they are trained and interested in a specific area than those not trained, or even not having any particular interest in that specific area. Surgeons committed to the trauma service had less missed injuries in severely injured patients, and it is vital to improve patient safety and quality of care for trauma patients. Staff training and education for assessing severely injured patients and creating an open culture with detection and reduction of the potential for error are important and effective strategies in decreasing missed injuries and improving patient safety.

    This study examines burnout in a national sample of transplant surgeons. Data analyses were conducted on a sample of 209 actively practicing transplant surgeons. Measures included the Maslach Burnout Inventory, a demographic survey, and the Surgeon Coping Inventory. Burnout was reflected in 38% of surgeons scoring high on the Emotional Exhaustion dimension, whereas 27% showed high levels of Depersonalization, and 16% had low levels of Personal Accomplishment. Several significant predictors of emotional exhaustion were identified and included questioning one's career choice, giving up activities, and perceiving oneself as having limited control over the delivery of medical services (R2= 0.43). Those who perceived themselves as having a higher ability to control delivery of medical services and who felt more appreciated by patients had lower levels of depersonalization and were less likely to question their career choice (R2= 0.16). Surgeons with high personal accomplishment experienced greater professional growth opportunities, perceived their institution as supportive, felt more appreciated by patients, and were less likely to question their career (R2= 0.24). The prioritization of goals to reflect both professional and personal values accounted for a significant amount of the variance in predicting both emotional exhaustion and personal accomplishment in separate regression equations. Recommendations to decrease burnout would include greater institutional support, increased opportunities for professional growth, and greater surgeon control over important services to facilitate efficient work. Coping strategies to moderate stress and burnout are also beneficial and should include prioritizing goals to reflect both professional and personal values.

  12. Depth Perception of Surgeons in Minimally Invasive Surgery.

    2016-10-01

    Minimally invasive surgery (MIS) poses visual challenges to the surgeons. In MIS, binocular disparity is not freely available for surgeons, who are required to mentally rebuild the 3-dimensional (3D) patient anatomy from a limited number of monoscopic visual cues. The insufficient depth cues from the MIS environment could cause surgeons to misjudge spatial depth, which could lead to performance errors thus jeopardizing patient safety. In this article, we will first discuss the natural human depth perception by exploring the main depth cues available for surgeons in open procedures. Subsequently, we will reveal what depth cues are lost in MIS and how surgeons compensate for the incomplete depth presentation. Next, we will further expand our knowledge by exploring some of the available solutions for improving depth presentation to surgeons. Here we will review the innovative approaches (multiple 2D camera assembly, shadow introduction) and devices (3D monitors, head-mounted devices, and auto-stereoscopic monitors) for 3D image presentation from the past few years.

    Individual performance indicators for cardiac surgeons in the UK were published in 2004. A comprehensive update published in 2009 reported statistically significant decreases in mortality rates suggesting that the publication of this data may have contributed to this improvement in outcomes. In view of this, the authors present an assessment of the attitudes of cardiac surgeons to individual performance tables, having performed this by sending questionnaires exploring the surgeon's views on performance tables to UK cardiac surgeons in 2005 and 2009. The responses demonstrated that whilst the majority of cardiac surgeons (68.8%) were initially opposed to performance tables, the number welcoming their introduction increased significantly (22.9-48.5%) over the four-year period. The attitude of the consultants towards the possible effect of this data on the management of high-risk patients also changed, with fewer consultants believing they would (P=0.0001) or may (P=0.023) avoid these patients. The observed change in attitude of cardiac surgeons may be due to acclimatization to an established system of audit, improved mortality rates, a desire for more transparency following the Bristol Enquiry, or improved risk stratification. These findings may be of benefit to those tasked with initiating these indicators elsewhere.

    Surgery is a demanding and stressful field in Korea. Occupational stress can adversely affect the quality of care, decrease job satisfaction, and potentially increase medical errors. The aim of this study was to investigate the occupational stress and career satisfaction of Korean surgeons. We have conducted an electronic survey of 621 Korean surgeons for the occupational stress. Sixty-five questions were used to assess practical and personal characteristics and occupational stress using the Korean occupational stress scale (KOSS). The mean KOSS score was 49.31, which was higher than the average of Korean occupational stress (45.86) or that of other specialized professions (46.03). Young age, female gender, long working hours, and frequent night duties were significantly related to the higher KOSS score. Having spouse, having hobby and regular exercise decreased the KOSS score. Multiple linear regression analysis showed that long working hours and regular exercise were the independent factors associated with the KOSS score. Less than 50% of surgeons answered that they would become a surgeon again. Most surgeons (82.5%) did not want to recommend their child follow their career. Korean Surgeons have high occupational stress and low level of career satisfaction.

    Full Text Available Abstract Background Emergency surgery has become a neglected specialization in Europe and in many other parts of the world. In certain medical fields, emergency surgery isn't even considered an autonomous specialization. However every emergency surgeon must have a good formation in General Surgery but exist huge disparities between different European surgical formative systems. Methods An analysis of the main problems of the European surgical formative system was conducted. Results This discrepancy between formative systems is absolutely unacceptable and presents a notable hazard for the European Union, considering that surgical certifications are reciprocally recognized between programs within all European Union states. Conclusion Considering the increasing possibilities to move inside the European Union, is necessary to improve the European surgical formative system to warrant an uniform formation for all surgeons.

    Introduction: Much is debated on the quality of life of pediatric surgeons practicing in India, all based on anecdotal and personal experiences. There is no systematic study on this. This study addresses this and attempts to glean a clearer picture of the life as a pediatric surgeon in India. Methodology: This questionnaire-based study was administered via an online survey to all Indian Association of Pediatric Surgeons members. The responses were anonymous and investigators blinded. Data were collated and analyzed using STAT11.1. Results: A total of 173 pediatric surgeons responded. Eighty-six percent were men. About 73.7% of the surgeons were between 31 and 50 years of age. Almost 63.4% practiced in urban areas, whereas 36% in other smaller towns. About 0.6% reported that their practice was rural. Almost 26.4% were in private/solo practices, whereas 53.4% were in institution-based practice. Almost 80% felt that they were adequately trained while starting their practice. About 78% are professionally satisfied with their work. Only 44.5% of surgeons felt that they were compensated adequately financially. Reading was the favorite pass time. Almost 40% of the surgeons felt that they were either overweight or obese. About 41% of the surgeons exercise more than 3 times a week. Only 11.4% smoke, whereas 36% drink. Fifty-three percent of surgeons felt that their personal savings were adequate. Seventy-six percent use Facebook. Sixty-eight percent were satisfied with their quality of life. Age was significantly associated with professional satisfaction, financial satisfaction, and quality of life and all improve as one's age progresses. None were affected with one's gender, type of practice, and the place of practice. Age, weight, exercise, and one's savings significantly affected ones quality of life. Conclusion: This is the first study which objectively highlights that most surgeons are happy professionally and financially in due course of time and demolishes the common

    For the oral and maxillofacial surgeon, many patients will be on heparin products during surgery. So far, there is no standardized approach to treating anticoagulated patients during oral and maxillofacial surgical procedures. When a patient is on heparin therapy, heparin may be stopped 4 to 6 hours before surgery and resumed once hemostasis is achieved, usually within 24 hours. If low-molecular-weight heparin is administered, the treatment is generally stopped at least 12 hours before surgery and then resumed in a similar fashion. Local measures are generally enough to provide adequate hemostasis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available High-resolution ultrasound has gained increasing popularity as an aid in the diagnosis of rotator cuff pathology. With the advent of portable machines, ultrasound has become accessible to clinicians. Aim: This study was conducted to evaluate the accuracy and reliability of ultrasound in diagnosing rotator cuff tears by a shoulder surgeon and comparing their ability to that of a musculoskeletal radiologist. Materials and Methods: Seventy patients undergoing shoulder arthroscopy for rotator cuff pathology underwent preoperative ultrasonography (US. All patients were of similar demographics and pathology. The surgeon used a Sonosite Micromax portable ultrasound machine with a 10-MHz high frequency linear array transducer and the radiologist used a 9-12 MHz linear array probe on a Siemens Antares machine. Arthroscopic diagnosis was the reference standard to which ultrasound findings were compared. Results: The sensitivity in detecting full thickness tears was similar for both the surgeon (92% and the radiologist (94%. The radiologist had 100% sensitivity in diagnosing partial thickness tears, compared to 85.7% for the surgeon. The specificity for the surgeon was 94% and 85% for the radiologist. Discussion: Our study shows that the surgeons are capable of diagnosing rotator cuff tears with the use of high-resolution portable ultrasound in the outpatient setting. Conclusion: Office ultrasound, by a trained clinician, is a powerful diagnostic tool in diagnosing rotator cuff tears and can be used effectively in running one-stop shoulder clinics.

    We consider the solution of nonlinear programs in the case where derivatives of the objective function and nonlinear constraints are unavailable. To solve such problems, we propose an adaptation of a method due to Conn, Gould, Sartenaer, and Toint that proceeds by approximately minimizing a succession of linearly constrained augmented Lagrangians. Our modification is to use a derivative-free generating set direct search algorithm to solve the linearly constrained subproblems. The stopping criterion proposed by Conn, Gould, Sartenaer and Toint for the approximate solution of the subproblems requires explicit knowledge of derivatives. Such information is presumed absent in the generating set search method we employ. Instead, we show that stationarity results for linearly constrained generating set search methods provide a derivative-free stopping criterion, based on a step-length control parameter, that is sufficient to preserve the convergence properties of the original augmented Lagrangian algorithm.

    Full Text Available Objective: Robotic surgical systems offer better workplace in order to relieve surgeons from prolonged physical efforts and improve their surgical outcomes. However, robotic surgery could produce musculoskeletal disorders due to the prolonged sitting position of the operator, the fixed position of the console viewer and the movements of the limbs. Until today, no one study has been reported concerning the association between robotics and musculoskeletal pain. The aim of this work was verify the prevalence of musculoskeletal disorders among Italian robotic surgeons. Material and methods: Between July 2011 and April 2012 a modified Standardized Nordic Questionnaire was delivered to thirty-nine Italian robotic centres. Twentytwo surgeons (56% returned the questionnaires but only seventeen questionnaires (43.5% were evaluable. Results: Seven surgeons (41.2% reported musculoskeletal disorders, by since their first use of the robot which significantly persisted during the daily surgical activity (P < 0.001. Regarding the body parts affected, musculoskeletal disorders were mainly reported in the cervical spine (29.4% and in the upper limbs (23.5%. Six surgeons (35.3% defined the robotic console as less comfortable or neither comfortable/uncomfortable with a negative influence on their surgical procedures. Conclusions: In spite of some important limitations, our data showed musculoskeletal disorders due to posture discomfort with negative impact on daily surgical activity among robotic surgeons. These aspects could be due to the lack of ergonomic seat and to the fixed position of the console viewer which could have produced an inadequate spinal posture. The evaluation of these postural factors, in particular the development of an integrated and more ergonomic chair, could further improve the comfort feeling of the surgeon at the console and probably his surgical outcomes.

  3. GPHS-RTG system explosion test direct course experiment 5000. [General Purpose Heat Source-Radioisotope Thermoelectric Generator

    1984-03-01

    The General Purpose Heat Source-Radioisotope Thermoelectric Generator (GPHS-RTG) has been designed and is being built to provide electrical power for spacecrafts to be launched on the Space Shuttle. The objective of the RTG System Explosion Test was to expose a mock-up of the GPHS-RTG with a simulated heat source to the overpressure and impulse representative of a potential upper magnitude explosion of the Space Shuttle. The test was designed so that the heat source module would experience an overpressure at which the survival of the fuel element cladding would be expected to be marginal. Thus, the mock-up was placed where the predicted incident overpressure would be 1300 psi. The mock-up was mounted in an orientation representative of the launch configuration on the spacecraft to be used on the NASA Galileo Mission. The incident overpressure measured was in the range of 1400 to 2100 psi. The mock-up and simulated heat source were destroyed and only very small fragments were recovered. This damage is believed to have resulted from a combination of the overpressure and impact by very high velocity fragments from the ANFO sphere. Post-test analysis indicated that extreme working of the iridium clad material occurred, indicative of intensive impulsive loading on the metal.

  4. Direct oral anticoagulants in atrial fibrillation: can data from randomized clinical trials be safely transferred to the general population? No.

    2015-09-01

    Direct oral anticoagulants (DOAC) represent an innovative and relevant treatment for the prevention of cardiac embolism in patients with atrial fibrillation (AF). Their introduction has been followed by an ample debate on their appropriate use, considering that they can offer an effective treatment for the many patients with AF, which are not taking any effective anticoagulant treatment, even though they have a substantial thromboembolic risk (1). On the other hand, DOAC are much less tested in everyday clinical practice and much more expensive than anti-vitamin k anticoagulants (AVKs). Starting from the quite favorable results of the available randomized controlled trials (RCTs)--showing that DOAC are at least non-inferior to AVK and that may be even better for some outcomes--this article discusses their transferability to the majority of AF patients. In summary, the body of evidence supports the efficacy and safety of DOAC in patients carrying demographic and clinical characteristics similar to subjects included in RCT, but their use in less well-characterized subpopulations requires particular caution, while waiting for more reliable data from the real world.

  5. The changing health care marketplace: current industry trends, new provider organizational structures, and effects on plastic surgeons.

    1998-09-01

    Current market forces are driving the health care industry in new directions. The managed care industry is currently undergoing a market shakeout, as manifested by consolidation, increased competition, and lower profits. Medicare is fighting to remain solvent by lowering fees paid to providers, driving patients into managed care plans, and cracking down on billing irregularities. For providers, the combined effect of these trends is lower fees, increased risk-sharing, and increased overhead. Plastic surgeons face new demands in this environment. They must increase their efficiency and form new alliances with other providers. These alliances allow plastic surgeons to maintain a steady stream of patients, to manage risk, to negotiate more lucrative contracts with managed care organizations, and to increase efficiency. To achieve these alliances, plastic surgeons must alter the organizational structure of their practices. Several corporate practice models are becoming more prevalent; these include large group practices, physician practice management companies, and integrated delivery systems. Each structure has advantages for plastic surgeons, but each also requires plastic surgeons to trade varying degrees of financial and professional autonomy for market strength.

  6. Neurosurgeons in Japan Are Exclusively Brain Surgeons.

    2017-03-01

    In Japan, neurosurgeons have traditionally mainly treated brain diseases, with most cases involving the spine and spinal diseases historically being treated by orthopedists. Nowadays, spinal surgery is 1 of the many subspecialties in the neurosurgical field in Japan. Most patients with neurological deficits or suspected neurological diseases see board-certified neurosurgeons directly in Japan, not through referrals from family physicians or specialists in other fields. Problems originating in the spine and spinal cord have been overlooked or misdiagnosed in these situations. Neurosurgeons in Japan must rethink the educational program to include advanced trauma life support and spinal surgery. Copyright © 2016. Published by Elsevier Inc.

    Full Text Available Abstract Background Over the course of the past 40 years, there have been a significant number of changes in the way in which lymphomatous disease is diagnosed and managed. With the advent of computed tomography, there is little role for staging laparotomy and the surgeon's role may now more diagnostic than therapeutic. Aims To review all cases of lymphoma diagnosed at a single institution in order determine the current role of the surgeon in the diagnosis and management of lymphoma. Patients and methods Computerized pathology records were reviewed for a five-year period 1996 to 2000 to determine all cases of lymph node biopsy (incisional or excisional in which tissue was obtained as part of a planned procedure. Cases of incidental lymphadenopathy were thus excluded. Results A total of 297 biopsies were performed of which 62 (21% yielded lymphomas. There were 22 females and 40 males with a median age of 58 years (range: 19–84 years. The lymphomas were classified as 80% non-Hodgkin's lymphoma, 18% Hodgkin's lymphoma and 2% post-transplant lymphoproliferative disorder. Diagnosis was established by general surgeons (n = 48, ENT surgeons (n = 9, radiologists (n = 4 and ophthalmic surgeons (n = 1. The distribution of excised lymph nodes was: cervical (n = 23, inguinal (n = 15, axillary (n = 11, intra-abdominal (n = 6, submandibular (n = 2, supraclavicular (n = 2, periorbital (n = 1, parotid (n = 1 and mediastinal (n = 1. Fine needle aspiration cytology had been performed prior to biopsy in only 32 (52% cases and had suggested: lymphoma (n = 10, reactive changes (n = 13, normal (n = 5, inadequate (n = 4. The majority (78% of cervical lymph nodes were subjected to FNAC prior to biopsy whilst this was performed in only 36% of non-cervical lymphadenopathy. Conclusion The study has shown that lymphoma is a relatively common cause of surgical lymphadenopathy. Given the limitations of FNAC, all suspicious lymph nodes should be biopsied following FNAC even

    Minimally invasive repair of pectus excavatum (MIRPE) or similar procedures for pectus excavatum (PE) repair, nowadays no longer performed by one single speciality, may not always achieve sufficient aesthetic results, particularly in the infrapectoral or infraxiphoidal region. Reasons for this include the diaphragm inhibiting correct positioning of the bars, as well as asymmetric deformities which may still be present after remodelling attempts. Furthermore, some cases develop a mild recurrence or partial concavity once the correction bar is removed. However, any secondary re-do MIRPE procedure remains risky because of adhesions between the pleura, lung, pericardium, thoracic wall as residuals from the primary intervention. Treatment options as secondary correction for these deformities may include open access surgery, resection or reshaping of deformed costal cartilage. Moreover, augmentation of a residual concave area can be achieved by autologous transplantation of resected over-abundant cartilage, as well as by liposhifting or implantation of customized alloplastics. A physician dealing with PE corrections should be familiar with various shaping and complementary reconstructive techniques in order to provide the best options for a variety of expressions of anterior wall deformities. Among treating surgeons, there is an awareness that no single method can be applied for every kind of funnel chest deformity. An appropriate technique, either as a single approach for the ordinary deformities or in conjunction with ancillary procedures for the intricate cases, should be selected carefully based on the heterogeneity of symptoms, severity, expectations and surgical skill in addition to the available equipment. Out of a variety of such ancillary procedures available and based on experience within general plastic reconstructive surgery, some techniques for PE repair are explained and illustrated here with their advantages and disadvantages.

Medical records were reviewed for demographic information, preoperative nucleus grade, femtosecond laser pretreatment, operative procedure times, total operating room times, and surgical complications. Review of digital video records provided quantitative interval measurements of core steps of the procedures, including completion of incisions, anterior capsulotomy, nucleus removal, cortical removal, and intraocular lens implantation.Results: Total room time, operation time, and corneal incision completion time were found to be significantly longer in the femtosecond laser group versus the traditional phacoemulsification group (each P<0.05. Mean duration for manual completion of anterior capsulotomy was shorter in the laser group (P<0.001. There were no statistically significant differences in the individual steps of nucleus removal, cortical removal, or intraocular lens placement. Surgical complication rates were not significantly different between the groups.Conclusion: In early cases, resident completion of femtosecond cataract surgery is generally less efficient when trainees have more experience with traditional phacoemulsification. FLACS was found to have a significant advantage in completion of capsulotomy, but subsequent surgical steps were not shorter or longer. Resident learning curve for the

    While demand for cardiovascular surgery is expected to increase gradually along with the rapid increase in cardiovascular diseases with respect to the aging population, the supply of thoracic and cardiovascular surgeons has been continuously decreasing over the past 10 years. Consequently, this study aims to achieve guidance in establishing health care policy by analyzing the supply and demand for cardiovascular surgeries in the medical service area of Korea. After investigating the actual number of cardiovascular surgeries performed using the National Health Insurance claim data of the Health Insurance Review and Assessment Service, as well as drawing from national statistics concerning the elderly population aged 65 and over, this study estimated the number of future cardiovascular surgeries by using a cell-based model. To be able to analyze the supply and demand of surgeons, the recent status of new surgeons specializing in thoracic and cardiovascular surgeries and the ratio of their subspecialties in cardiovascular surgeries were investigated. Then, while taking three different scenarios into account, the number of cardiovascular surgeons expected be working in 5-year periods was projected. The number of cardiovascular surgeries, which was recorded at 10,581 cases in 2014, is predicted to increase consistently to reach a demand of 15,501 cases in 2040-an increase of 46.5%. There was a total of 245 cardiovascular surgeons at work in 2014. Looking at 5 year spans in the future, the number of surgeons expected to be supplied in 2040 is 184, to retire is 249, and expected to be working is 309-an increase of -24.9%, 1.6%, and 26.1%, respectively compared to those in 2014. This forecasts a demand-supply imbalance in every scenario. Cardiovascular surgeons are the most central resource in the medical service of highly specialized cardiovascular surgeries, and fostering the surgeons requires much time, effort, and resources; therefore, by analyzing the various factors

    The origins of New Spain Inquisition whose jurisdiction extended also to Philippine Islands, are related herein. Physicians and surgeons who worked as Inquisition officers are discussed, from the first Dr. Juan de la Fuente who was appointed on May 9, 1572, to Dr. Pedro del Castillo, appointed on September 24, 1644. Likewise, physicians and surgeons judged by the Holy Office are mentioned. During the XVI century, those judged were few and insignificant personages, the first was the Irish Protestant William Corniels a barber surgeon, who arrived with the John Hawkins' pirate fleet in 1568 and settled in Guatemala. Some physicians and surgeons were judged as "Judaizers" during the first half of the XVII century. Many physicians and surgeons were prosecuted in Mexico, as well as in the Philippine Islands, in the second half of the XVIII century because they were Freemasons or supporters of French Revolution ideology. Among those was the unfortunate Dr. Enrique Esteban Morel, who introduced into Mexico the method of antivariolar inoculation at the time of the great epidemic out-break of 1779. It should be a gesture of justice to build a memorial in the ancient Inquisition Palace to honor this Public Health's worthy physician.

    Surgeons are the physician group most commonly identified as "disruptive physicians." The aim of this study was to develop a conceptual model of the results of disruptive surgeon behavior and to identify the coping strategies used by perioperative staff. Perspectives of 19 individuals of diverse occupations in the perioperative setting were drawn together using a grounded theory methodology. Effects of disruptive behavior described by participants included shift in attention from the patient to the surgeon, increased mistakes during procedures, deterrence from careers in surgery, and diminished respect for surgeons. Individual coping strategies employed in the face of intimidation include talking to colleagues, externalizing the behavior, avoidance of perpetrators, and warning others. Using grounded theory analysis, we were able to elucidate the impact of disruptive surgeon behavior in the perioperative environment. This conceptual model may be used to understand and counter the negative effects of manipulation and intimidation of hospital staff and trainees and to build on current programmatic strengths to improve surgical environments and training.

    2016-10-04

    Antibiotic resistance continues to receive national attention as a leading public health threat. In 2015, President Barack Obama proposed a National Action Plan to Combat Antibiotic-Resistant Bacteria to curb the rise of "superbugs," bacteria resistant to antibiotics of last resort. Whereas many antibiotics are prescribed appropriately to treat infections, there continue to be a large number of inappropriately prescribed antibiotics. Although much of the national attention with regards to stewardship has focused on primary care providers, there is a significant opportunity for surgeons to embrace this national imperative and improve our practices. Local quality improvement efforts suggest that antibiotic misuse for surgical disease is common. Opportunities exist as part of day-to-day surgical care as well as through surgeons' interactions with nonsurgeon colleagues and policy experts. This article discusses the scope of the antibiotic misuse in surgery for surgical patients, and provides immediate practice improvements and also advocacy efforts surgeons can take to address the threat. We believe that surgical antibiotic prescribing patterns frequently do not adhere to evidence-based practices; surgeons are in a position to mitigate their ill effects; and antibiotic stewardship should be a part of every surgeons' practice.

    Guidelines recommend that oncologists discuss treatment-related fertility issues with young cancer patients as early as possible after diagnosis and, if appropriate, expedite referral for fertility preservation (FP). This study sought to determine the attitudes and practices of Canadian breast surgeons regarding fertility issues, as well as barriers to and facilitators of fertility discussion and referrals. Semistructured telephone interviews were conducted with 28 site lead surgeons (SLSs) at 28 (97 %) of 29 centers (25 % cancer centers, 64 % teaching hospitals) across Canada participating in RUBY, a pan-Canadian research program for young women with breast cancer. In addition, 56 (65 %) of 86 of their surgical colleagues (non-site lead surgeons [NSLSs]) completed an online survey of their oncofertility knowledge, attitudes, and practices. Of the 28 SLSs (43 % male, 36 % in practice knowledge, 25 % discussed fertility only if mentioned by the patient, 21 % believed fertility discussion and referral were the mandate of the medical oncologist, and 45 % did not know of an FP center in their area. More than 80 % of the NSLSs (54 % male, 30 % in practice knowledge was low among the SLSs, especially the NSLSs, and barriers to referral were identified. An oncofertility knowledge translation intervention specifically for breast surgeons is being developed to increase surgeon knowledge and awareness of oncofertility issues and referral.

  16. The Adenovirus E4-ORF3 Protein Stimulates SUMOylation of General Transcription Factor TFII-I to Direct Proteasomal Degradation

    Rebecca G. Bridges

    2016-01-01

    Full Text Available Modulation of host cell transcription, translation, and posttranslational modification processes is critical for the ability of many viruses to replicate efficiently within host cells. The human adenovirus (Ad early region 4 open reading frame 3 (E4-ORF3 protein forms unique inclusions throughout the nuclei of infected cells and inhibits the antiviral Mre11-Rad50-Nbs1 DNA repair complex through relocalization. E4-ORF3 also induces SUMOylation of Mre11 and Nbs1. We recently identified additional cellular targets of E4-ORF3 and found that E4-ORF3 stimulates ubiquitin-like modification of 41 cellular proteins involved in a wide variety of processes. Among the proteins most abundantly modified in an E4-ORF3-dependent manner was the general transcription factor II–I (TFII-I. Analysis of Ad-infected cells revealed that E4-ORF3 induces TFII-I relocalization and SUMOylation early during infection. In the present study, we explored the relationship between E4-ORF3 and TFII-I. We found that Ad infection or ectopic E4-ORF3 expression leads to SUMOylation of TFII-I that precedes a rapid decline in TFII-I protein levels. We also show that E4-ORF3 is required for ubiquitination of TFII-I and subsequent proteasomal degradation. This is the first evidence that E4-ORF3 regulates ubiquitination. Interestingly, we found that E4-ORF3 modulation of TFII-I occurs in diverse cell types but only E4-ORF3 of Ad species C regulates TFII-I, providing critical insight into the mechanism by which E4-ORF3 targets TFII-I. Finally, we show that E4-ORF3 stimulates the activity of a TFII-I-repressed viral promoter during infection. Our results characterize a novel mechanism of TFII-I regulation by Ad and highlight how a viral protein can modulate a critical cellular transcription factor during infection.

    2011-11-01

    Full Text Available Introduction: The last two decades have seen the adoption of simulation-based surgical education in various disciplines. The current study’s goal was to perform a needs assessment using the results to inform future curricular planning and needs of surgeons and learners. Methods: A survey was distributed to 26 surgeon educators and interviews were conducted with 8 of these surgeons.  Analysis of survey results included reliability and descriptive statistics. Interviews were analyzed for thematic content with a constant comparison technique, developing coding and categorization of themes. Results: The survey response rate was 81%. The inter-item reliability, according to Cronbach’s alpha was 0.81 with strongest agreement for statements related to learning new skills, training new residents and the positive impact on patient safety and learning.   There was less strong agreement for maintenance of skills, improving team functioning and reducing teaching in the operating room. Interview results confirmed those themes from the survey and highlighted inconsistencies for identified perceived barriers and a focus on acquisition of skills only.  Interview responses specified concerns with integrating simulation into existing curricula and the need for more evaluation as a robust educational strategy. Conclusion: The findings were summarized in four themes: 1 use of simulation, 2 integration into curriculum, 3 leadership, and 4 understanding gaps in simulation use. This study exemplifies a mixed-methods approach to planning a surgical simulation program through a general needs assessment.

    Although many older adults prefer to avoid burdensome interventions with limited ability to preserve their functional status, aggressive treatments, including surgery, are common near the end of life. Shared decision making is critical to achieve value-concordant treatment decisions and minimize unwanted care. However, communication in the acute inpatient setting is challenging. To evaluate the proof of concept of an intervention to teach surgeons to use the Best Case/Worst Case framework as a strategy to change surgeon communication and promote shared decision making during high-stakes surgical decisions. Our prospective pre-post study was conducted from June 2014 to August 2015, and data were analyzed using a mixed methods approach. The data were drawn from decision-making conversations between 32 older inpatients with an acute nonemergent surgical problem, 30 family members, and 25 surgeons at 1 tertiary care hospital in Madison, Wisconsin. A 2-hour training session to teach each study-enrolled surgeon to use the Best Case/Worst Case communication framework. We scored conversation transcripts using OPTION 5, an observer measure of shared decision making, and used qualitative content analysis to characterize patterns in conversation structure, description of outcomes, and deliberation over treatment alternatives. The study participants were patients aged 68 to 95 years (n = 32), 44% of whom had 5 or more comorbid conditions; family members of patients (n = 30); and surgeons (n = 17). The median OPTION 5 score improved from 41 preintervention (interquartile range, 26-66) to 74 after Best Case/Worst Case training (interquartile range, 60-81). Before training, surgeons described the patient's problem in conjunction with an operative solution, directed deliberation over options, listed discrete procedural risks, and did not integrate preferences into a treatment recommendation. After training, surgeons using Best Case/Worst Case clearly presented a choice between

    Education in the knowledge, skills, and attitudes necessary for a surgeon to perform at an expert level in the operating room, and beyond, must address all potential cognitive and technical performance gaps, professionalism and personal behaviors, and effective team communication. Educational strategies should also seek to replicate the stressors and distractions that might occur during a high-risk operation or critical care event. Finally, education cannot remain fixed in an apprenticeship model of "See one, do one, teach one," whereby patients are exposed to the risk of harm inherent to any learning curve. The majority of these educational goals can be achieved with the addition of simulation-based education (SBE) as a valuable adjunct to traditional training methods. This article will review relevant principles of SBE, explore currently available simulation-based educational tools for pediatric surgeons, and finally make projections for the future of SBE and performance assessments for pediatric surgeons.

    Communication between the bariatric surgeon and the obese patient is very important as it influences the expectations of patients with regard to surgery, aim of the surgery and the understanding of the mechanisms of failure of surgery. Furthermore, the incidence of certain psychopathology in these patients makes it necessary for the surgeon to have the ability to communicate to the patient the need for motivation and the maintenance of healthy life habits. Although the topic is subjective, in this article we review several useful recommendations to optimize communication before and after surgery. Finally, we emphasize the need to create workshops to train the bariatric surgeon in these issues that we consider so important. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U.

    This article reviews the pioneering efforts of Joseph Bell, the model for Sherlock Holmes, in the surgical care of children during the antiseptic era. I reviewed biographies of Sir Arthur Conan Doyle; the biography of Joseph Bell; his surgical textbook, Edinburgh Medical Journals; and the history of the Royal Edinburgh Hospital for Sick Children. Dr Bell was a colleague of Joseph Lister and one of the first surgeons to apply antiseptic methods to operations involving children. He was the surgeon appointed to the first surgical ward of the Royal Edinburgh Hospital for Sick Children; in that role, he cared for many children with surgical diseases. Dr Joseph Bell, by his compassion for children and his surgical skill, was indeed a pioneer pediatric surgeon. Copyright 2010 Elsevier Inc. All rights reserved.

    The present day healthcare system in Germany is rapidly changing, even more so after the introduction of diagnosis-related groups. The basic requirements for every surgeon remain manual skills, a profound clinical knowledge and the ability for clinical decision-making even in difficult situations. However, these key elements of surgical education no longer fulfill the requirements for today's leaders in surgery. New requirements, consisting of administrative duties, strategic decision-making and department management are too complex to be made only intuitively. Nowadays surgeons also need a profound education in management skills and knowledge of economic mechanisms in order to run an efficient, profitable, patient-oriented surgical department. Every surgeon who aims at obtaining a leadership position should acquire the necessary knowledge and skills.

    The integrity of the medical literature about robotic surgery remains unclear despite wide-spread adoption. We sought to determine if payment from Intuitive Surgical Incorporated (ISI) affected quality of the research produced by surgeons. Publicly available financial data from the CMS website regarding the top-20 earners from ISI for 2015 was gathered. Studies conducted by these surgeons were identified using PubMed. Inclusion criteria consisted of publications about the da Vinci(®) robot on patient outcomes. The primary outcome of our study was if the study conclusion was positive/equivocal/negative towards the robot. Secondary outcomes included authorship, sponsorship, study controls, and disclosure. The top earners received $3,296,844 in 2015, with a median of $141,959. Sub-specialties included general surgery (55%), colorectal (20%), thoracic (15%), and obstetrics/gynecology (10%). Of the 37 studies, there was 1 RCT, with observational studies comprising the rest. The majority of the studies (n = 16, 43%) had no control population, with 11 (30%) comparing to same institution/surgeon, Though ISI sponsored only 6 (16%) studies, all with positive conclusions, 27 (73%) studies had positive conclusions for robot use, 9 (24%) equivocal, and only 1 (3%) negative. Overall, 13 earners had lead authorship and 11 senior. This initial pilot study highlights a potential bias as current literature published by benefactors demonstrates low quality and highly positive conclusions towards approval of the robot. This substantiates the need for a large, systematic review of the potential influence of sponsoring surgeons on medical literature. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Several studies have shown that wound infection (surgical site infection [ ssi ] rates fall when surgeons are provided with data on their performance. Since 1987, the authors have been performing concurrent surveillance of surgical patients and confidentially reporting surgeon-specific ssi rates to individual surgeons and their clinical directors, and providing surgeons with the mean rates of their peers. The program has been gradually refined and expanded. Data are now collected on wound infection risk and report risk adjusted rates compared with the mean for hospitals in the United States National Nosocomial Infections Surveillance (nnis data bank. Since inception through to December 1993, ssi rates have fallen 68% in clean contaminated general surgery cases (relative risk [rr] 0.36, 95% ci 0.2 to 0.6, P=0.0001, 64% in clean plastic surgery cases (rr 0.35, 95% ci 0.06 to 1.8, 72% in caesarean section cases (rr 0.23, 95% ci 0.03 to 1.96 and 42% in clean cardiovascular surgery cases (rr 0.59, 95% ci 0.34 to 1.0. In clean orthopedic surgery the ssi rate remained stable from 1987 through 1992. In 1993 a marked increase was experienced. Reasons for this are being explored. Overall there was a 32% decrease in ssi rate between the index year and 1993 or, in percentage terms, 2.8% to 1.9% (rr 0.65, 95% ci 0.51 to 0.86, P=0.002. ssi surveillance should become standard in Canadian hospitals interested in improving the quality of surgical care and reducing the clinical impact and cost associated with nosocomial infection.

    Anorectal procedures are often performed in an outpatient setting using a variety of anesthetic techniques. One technique that has not been well studied is surgeon-administered conscious sedation along with local anesthetic. The purpose of this study was to evaluate the use of this technique with emphasis on safety, efficacy, and patient satisfaction. Chart review was performed on 133 consecutive patients who had anorectal procedures at an outpatient surgery center. Additionally, 65 patients were enrolled prospectively and completed a satisfaction survey. Inclusively, charts of 198 patients who underwent outpatient anorectal surgery under conscious sedation and local anesthesia under the direction of a colorectal surgeon from 2004 through 2008 were reviewed. Parameters related to patient and procedural characteristics, safety, efficacy, and satisfaction were evaluated. Surgeon-administered sedation consisted of combined fentanyl and midazolam in 90 per cent. Eighty per cent of procedures were performed in the prone position and 23 per cent were in combination with an endoscopic procedure. Eighty-two per cent were classified as American Society of Anesthesiologists Grade 1 or 2. Transient mild hypoxemia or hypotension occurred in 4 and 3 per cent of the patients, respectively. Mean operative time was 29 minutes with a mean stay in the postanesthesia care unit of 37 minutes. There were no early major cardiac or respiratory complications. Ninety-seven per cent of the patients surveyed reported a high degree of satisfaction. Surgeon-administered conscious sedation with local anesthesia was well tolerated for outpatient anorectal surgeries. Additional studies are needed to confirm the safety and efficacy of this technique.

    The purpose of our study was to assess safety and efficacy of cataract surgery (CS) under topical anesthesia alone, i.e. without pre-anesthetic evaluation and without direct presence of an anesthesiologist. To this end we assessed the incidence of patients' preoperative anxiety, perioperative adverse events and patients' and surgeons' satisfaction. Patients undergoing CS under topical anesthesia over a one-month period were included. An anesthesiologist and nurse anesthetist were present in the area and could intervene in case of an adverse event. Patients' anxiety was scored using the Amsterdam Preoperative Anxiety & Information Scale (APAIS), and their satisfaction with the Iowa Satisfaction with Anesthesia Scale (ISAS). Surgeons' satisfaction was scored with a VAS from 0 to 10 (0: surgery not possible & 10: excellent surgical conditions). One hundred and twenty-four consecutive patients were included; mean age was 71 (±9.4) years. Mean APAIS I was 6.4/20 (±3.7). Mean APAIS II was 3.1 (±1.8). Mean ISAS score was 5.5/6 (±0.6), indicating high patient satisfaction. Surgeon satisfaction score was 8.9/10 (±1.7). Twenty-three adverse events occurred of which 16 required interventions by the anaesthesiologist or surgeon: 5 supplemental local or regional anaesthesia, 6 iv-analgesia, 5 management of hypertension. These preliminary data suggest that a simplified topical anesthesia protocol for ambulatory CS appears to be feasible and safe, as long as an anesthesia team is present in the area to intervene if needed.

    In addition to technical expertise, surgical competence requires effective non-technical skills to ensure patient safety and maintenance of standards. Recently the Royal Australasian College of Surgeons implemented a new Surgical Education and Training (SET) curriculum that incorporated non-technical skills considered essential for a competent surgeon. This study sought to compare the non-technical skills of experienced surgeons who completed their training before the introduction of SET with the non-technical skills of more recent trainees. Surgical trainees and experienced surgeons undertook a simulated scenario designed to challenge their non-technical skills. Scenarios were video recorded and participants were assessed using the Non-Technical Skills for Surgeons (NOTSS) scoring system. Participants were divided into subgroups according to years of experience and their NOTSS scores were compared. For most NOTSS elements, mean scores increased initially, peaking around the time of Fellowship, before decreasing roughly linearly over time. There was a significant downward trend in score with increasing years since being awarded Fellowship for six of the 12 NOTSS elements: considering options (score -0·015 units per year), implementing and reviewing decisions (-0·020 per year), establishing a shared understanding (-0·014 per year), setting and maintaining standards (-0·024 per year), supporting others (-0·031 per year) and coping with pressure (-0·015 per year). The drop in NOTSS score was unexpected and highlights that even experienced surgeons are not immune to deficiencies in non-technical skills. Consideration should be given to continuing professional development programmes focusing on non-technical skills, regardless of the level of professional experience. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Full Text Available Background and rationale of the study: Although Sharps injuries are a preventable hazard faced by medical personnel in the operating room yet it continues to be one of the hidden problems among HCP. The potential consequence of such injuries includes transmission of blood-borne pathogens with detrimental effects. Despite the advances in technology and increased awareness of medical staff, annually around 600 thousand to one million workers are affected thus considered as one of the most serious threats facing health care workers specially surgeon.Methodology: a cross sectional study of Zagazig University Hospitals surgical departments. Using a sample composed of 287 surgeons randomly chosen from different surgical departments. A questionnaire assessed in addition to personal and professional characteristics, the history of sharp injuries, types of instrument causing the injury, their post exposure prophylaxis including reporting. The results: There were total 287 surgeons participated in this study. (47% of the respondent surgeons had been exposed to at least one episode of sharp injury in the preceding 3 months and most of the exposures (68% occurred in the operation room. The injury was mainly caused during suturing (83%. The commonest devices, accused in most of the injuries were suturing needle and scalpel (74 and 59%. The majority of the surgeons (62% didn’t report the SI and it was largely explained by the majority of the sampled respondents (89% were not aware of the reporting system existing in their hospital.Conclusions: The most common reason of underreporting  in our study was the lack of awareness that all injuries must be reported.Recommendations: The observed high level of under reporting reflects the need for education on prevention. Our results can guide in planning an education program for the surgeons to increase awareness about dangers of sharp injuries and help improve the reporting strategy  and other potential

    The use of epidural ropivacaine may result in significant haemodynamic fluctuations during combined epidural and general anaesthesia. We designed this study to investigate whether epidural anaesthesia with a goal-directed approach, when combined with general anaesthesia, improved haemodynamic stability in elderly patients undergoing major abdominal surgery. Seventy-five elderly patients undergoing major abdominal surgery were randomly and evenly assigned to one of three groups receiving intraoperative epidural anaesthesia with either ropivacaine 0.1% (Group 1), ropivacaine 0.375% (Group 2) or ropivacaine 0.375% for abdominal wall pain and ropivacaine 0.1% for visceral pain (Group 3). General anaesthesia was induced using a target-controlled infusion of combined propofol and remifentanil. The remifentanil target concentration was adjusted according to the mean arterial pressure and heart rate, and vasoactive agents were administered to maintain stable haemodynamics. The need for vasoactive drug administrations was 1.4 (standard deviation 0.9) in Group 3 (n=24), representing a significantly lower frequency of administration compared with Groups 1 (n=24) and 2 (n=24) (P epidural anaesthesia with different ropivacaine concentrations can improve haemodynamic stability when combined with general anaesthesia for elderly patients undergoing major abdominal surgery.

    Periods of economic downturn place special demands on the plastic surgeon whose practice involves a large amount of cosmetic surgery. When determining strategy during difficult economic times, it is useful to understand the macroeconomic background of these downturns and to draw lessons from businesses in other service industries. Business cycles and monetary policy determine the overall environment in which plastic surgery is practiced. Plastic surgeons can take both defensive and proactive steps to maintain their profits during recessions and to prepare for the inevitable upturn. Care should also be taken when selecting pricing strategy during economic slowdowns.

    Full Text Available Patient-specific bone and joint replacement implants lead to better functional and aesthetic results than conventional methods [1], [2], [3]. But extracting 3D shape information from CT Data and designing individual implants is demanding and requires multiple surgeon-to-engineer interactions. For manufacturing purposes, Additive Manufacturing offers various advantages, especially for low volume manufacturing parts, such as patient specific implants. To ease these new approaches and to avoid surgeon-to-engineer interactions a new design software approach is needed which offers highly automated and user friendly planning steps.

    Workers' compensation is an employer-funded insurance program that provides financial and medical benefits for employees injured at work. Because many occupational injuries are musculoskeletal in nature, the orthopaedic surgeon plays an important role in the workers' compensation system. Along with establishing the correct diagnosis and implementing an appropriate treatment plan, the clinician must understand the fundamental components of the workers' compensation system to manage an injured employee. Ultimately, effective claim management requires collaboration among the employer, the employee, the legal representatives, the insurance company, and the orthopaedic surgeon.

  16. Surgeon`s adherence to guidelines for surgical antimicrobial prophylaxis-a review

    Directory of Open Access Journals (Sweden)

    Ru Shing Ng

    2012-05-01

    Full Text Available AbstractSurgical site infections are the most common nosocomial infection among surgical patients. Patients who experience surgical site infections are associated with prolonged hospital stay, rehospitalisation, increased morbidity and mortality, and costs. Consequently, surgical antimicrobial prophylaxis (SAP, which is a very brief course of antibiotic given just before the surgery, has been introduced to prevent the occurrence of surgical site infections. The efficacy of SAP depends on several factors, including selection of appropriate antibiotic, timing of administration, dosage, duration of prophylaxis and route of administration. In many institutions around the globe, evidence-based guidelines have been developed to advance the proper use of SAP. This paper aims to review the studies on surgeons’ adherence to SAP guidelines and factors influencing their adherence. A wide variation of overall compliance towards SAP guidelines was noted, ranging from 0% to 71.9%. The misuses of prophylactic antibiotics are commonly seen, particularly inappropriate choice and prolonged duration of administration. Lack of awareness of the available SAP guidelines, influence of initial training, personal preference and influence from colleagues were among the factors which hindered the surgeons’ adherence to SAP guidelines. Immediate actions are needed to improve the adherence rate as inappropriate use of SAP can lead to the emergence of a strain of resistant bacteria resulting in a number of costs to the healthcare system. Corrective measures to improve SAP adherence include development of guidelines, education and effective dissemination of guidelines to targeted surgeons and routine audit of antibiotic utilisation by a dedicated infection control team.

    It is chronically surplus of doctors in the world of cardiac surgery. There are too many cardiac surgeons because cardiac surgery requires a large amount of manpower resources to provide adequate medical services. Many Japanese cardiac surgeons do not have enough opportunity to perform cardiac surgery operations, and many Japanese cardiac surgery residents do not have enough opportunity to learn cardiac surgery operations. There are physician assistants and nurse practitioners in the US. Because they provide a part of medical care to cardiac surgery patients, American cardiac surgeons can focus more energy on operative procedures. Introduction of cardiac surgery specialized nurse practitioner is essential to deliver a high quality medical service as well as to solve chronic problems that Japanese cardiac surgery has had for a long time.

  18. Isolated specialist or system integrated physician – different views on sickness certification among orthopaedic surgeons: an interview study

    Directory of Open Access Journals (Sweden)

    Swartling Malin

    2008-12-01

    Full Text Available Abstract Background Sickness certification is a frequent and sometimes problematic task for orthopaedic surgeons. Our aim was to explore how orthopaedic surgeons view their sick-listing commission and sick-listing practice. Methods Semi-structured interviews with seventeen orthopaedic surgeons from five orthopaedic clinics in four Swedish counties. The focus was on the experiences of these physicians in relation to handling of sickness certification. Phenomenographic analysis was performed to reveal differences in existing views. Results The orthopaedic surgeons' views on sick-listing seemed mainly to be a consequence of how they perceived their role in the healthcare system. Three categories were found: The "isolated specialists", whose work and responsibilities were confined to the orthopaedic clinic, and did not really include sickness certification; the "orthopaedic advisers", who saw themselves mainly as advice-givers in the general health care system and perceived sickness certification as part of their job; the "system-integrated physicians", who perceived the orthopaedic clinic as one part of the healthcare system and whose ultimate goal was to get the patient well functioning in her life again with regained work ability, seeing sick-listing as one of the instruments to achieve this. Some informants described difficulties in handling conflicting opinions with patients in relation to the need for sick-leave. Conclusion Orthopaedic surgeons certify a large proportion of total sickness benefits. Some orthopaedic surgeons may certify sickness benefits sub-optimally for patients and society due to a narrow view of their role in the health care system or due to poor skills in handling discordant opinions with the patient. This problem can be addressed at the level of the individual physician and at the system level.

  19. A general strategy to facilely design ratiometric electrochemical sensors in electrolyte solution by directly using a bare electrode for dual-signal sensing of analytes.

    2017-01-01

    In this paper, we have described a general strategy to facilely design ratiometric electrochemical sensors in electrolyte solutions, directly using a bare electrode for dual-signal sensing of analytes. Two types of substances (methylene blue/MB, doxorubicin/DOX) with different electrochemical signal peaks were added into electrolyte solutions (phosphate buffered saline, NaCl), where one was the analyte (DOX) and the other was used as a reference (MB). A linear plotting of DOX concentration [DOX] versus ratiometric electrochemical signal peak intensity (IDOX/IMB) was achieved, with a good linear coefficient and low detection limit of DOX (0.4nM). Experimental results implied that this ratiometric electrochemical sensor (ECS) of DOX enabled highly selective and sensitive detection of DOX in real samples, with high detection recoveries. In comparison with previous reports about ratiometric ECS, this as-proposed strategy can directly fabricate a ratiometric ECS in electrolyte solution (not on electrode), only using a bare electrode for dual- signal sensing of analytes. This strategy is not only novel and facile, but also flexible and general, as adequately confirmed in experiments, which would facilitate a further development in the facile fabrication and efficient applications of electrochemical sensors.

    2016-11-01

    The new direct oral anticoagulants-dabigatran etexilate, rivaroxaban, and apixaban- have predictable pharmacokinetic and pharmacodynamic profiles and are alternatives to warfarin. However, many surgeons are wary of these drugs, as there is limited evidence on how to manage bleeding in patients taking them, and only recently has a specific antidote been developed to reverse their anticoagulant effect. Management of the newer agents requires careful adherence to primary measures of bleeding care, knowledge of their mechanism of action, and familiarity with the unapproved and untested reversal strategies that may be required in patients with life-threatening bleeding.

    To determine the extent to which members of the general population have talked to their physician about their wishes regarding medical treatment at the end of life, to describe the prevalence of advance directives on euthanasia, and to identify associated factors. This study used data from the cross-sectional Health Interview Study (HIS) 2008 that collected data from a representative sample (N = 9651) of the Belgian population. Of all respondents, 4.4 % had spoken to their physician about their wishes regarding medical treatment at the end of life, while 1.8 % had an advance directive on euthanasia. Factors positively associated with discussions regarding wishes for medical treatment at the end of life were being female, being older in age, having poorer health status and having more GP contacts. People older than 55 years and living in Flanders or Brussels were more likely than the youngest age categories to have an advance directive on euthanasia. Younger people, men, people living in the Walloon region of Belgium, people without a longstanding illness, chronic condition or disability and people with few GP contacts could represent a target group for education regarding advance care planning. Public information campaigns and education of physicians may help to enable the public and physicians to engage more in advance care planning.

    Dual antiplatelet therapy is the cornerstone treatment for patients with acute coronary syndrome. Recent Canadian Guidelines recommend the use of dual antiplatelet therapy for 1 year after coronary artery bypass grafting in patients with acute coronary syndrome, but considerable variability remains. We performed a survey of 75 Canadian cardiac surgeons to assess the use of dual antiplatelet therapy. Whereas 58.6% of respondents indicated that the benefits of dual antiplatelet therapy were seen irrespective of how patients were managed after acute coronary syndrome, 36.2% believed that the benefits of dual antiplatelet therapy were limited to those treated medically or percutaneously. In regard to the timing of dual antiplatelet therapy administration, 57% of respondents indicated that dual antiplatelet therapy should be given upstream in the emergency department, whereas 36.2% responded that dual antiplatelet therapy should be given only once the coronary anatomy has been defined. The majority surveyed (81%) weighed bleeding risk as being more important than ischemic risk reduction. In stable patients after acute coronary syndrome, the majority of surgeons would wait approximately 4 days after the last dose of P2Y12 antagonist before coronary artery bypass grafting. Only 44.6% indicated that they routinely use dual antiplatelet therapy postrevascularization in the setting of acute coronary syndrome. Rather, most surgeons use dual antiplatelet therapy for select patients, such as those with a stented vessel without a bypass graft, endarterectomy, or off-pump coronary artery bypass grafting. Cardiac surgeons exhibit variation in their attitudes and practice patterns toward dual antiplatelet therapy after coronary artery bypass grafting, and in approximately half of cases, their practice does not adhere to current guideline recommendations.

    Full Text Available Yusta W Simwita, Berit I Helgheim Department of Logistics, Molde University College, Molde, Norway Purpose: Worldwide more than two billion people lack appropriate access to surgical services due to mismatch between existing human resource and patient demands. Improving utilization of existing workforce capacity can reduce the existing gap between surgical demand and available workforce capacity. In this paper, the authors use discrete event simulation to explore the care process at an orthopedic department. Our main focus is improving utilization of surgeons while minimizing patient wait time.Methods: The authors collaborated with orthopedic department personnel to map the current operations of orthopedic care process in order to identify factors that influence poor surgeons utilization and high patient waiting time. The authors used an observational approach to collect data. The developed model was validated by comparing the simulation output with the actual patient data that were collected from the studied orthopedic care process. The authors developed a proposal scenario to show how to improve surgeon utilization.Results: The simulation results showed that if ancillary services could be performed before the start of clinic examination services, the orthopedic care process could be highly improved. That is, improved surgeon utilization and reduced patient waiting time. Simulation results demonstrate that with improved surgeon utilizations, up to 55% increase of future demand can be accommodated without patients reaching current waiting time at this clinic, thus, improving patient access to health care services.Conclusion: This study shows how simulation modeling can be used to improve health care processes. This study was limited to a single care process; however the findings can be applied to improve other orthopedic care process with similar operational characteristics. Keywords: waiting time, patient, health care process

    The U.S. Centers for Medicare & Medicaid Services (CMS) recently released the Open Payments database (OPD) detailing payments from industry to physicians and teaching hospitals. We seek here to provide an overview of the data with a focus on the orthopaedic community. We analyzed payments in the OPD from August 1 to December 31, 2013. The OPD consists of three individual databases: General Payments, Research Payments, and Ownership. Physician identification number, physician specialty, payment type, and payment value were collected. Physicians assigned to multiple specialties were excluded. Comparisons were made between orthopaedic surgeons and the remainder of the top fifteen specialties by payment value. In all, 2,697,015 payments with physicians were recorded; 491,223 of these payments (18.2%) were made to physicians with multiple listed specialties and were excluded. Excluding these potentially misattributed payments did not have a significant impact on the trends identified, and $394.5 million in payments remained. Orthopaedic surgeons represented 3.4% of payments but 25.6% of value, and 13,347 orthopaedic surgeons (68.9% of all active orthopaedic surgeons) were listed in the OPD. Payments over $10,000 represented only 1.6% of payments to orthopaedic surgeons but 75.5% of value. The majority of these payments (56.1%) were royalties. The median payment value for orthopaedic surgeons listed in the OPD was $38.11, with two payments per surgeon; the median aggregated value was $132.56 per surgeon. Orthopaedic surgeons listed in the OPD were more likely to receive payments for travel compared with all other specialties (p orthopaedic surgeons and industry are highly prevalent. A small subset of orthopaedic surgeons received large royalties, which accounted for a majority of the transactional value provided by industry. Orthopaedic surgeons were the recipients of more payments for travel and for royalties than all other specialties except neurological surgery

    To detect and measure surgeons' head movement during laparoscopic simulator performance to determine whether expert surgeons have economy of motion in their head movement, including change of direction, compared with intermediate and novice surgeons. We investigated head movement as an objective tool for assessment of laparoscopic surgical skill and its potential use for assessing novice surgeons' progress on the learning curve. After obtaining institutional review board approval, medical students, urology residents, and attending staff surgeons from an academic institution were recruited. Participants were grouped by level of experience and performed tasks on the Electronic Data Generation for Evaluation laparoscopic simulator. Surgeons wore a commercially available wireless electroencephalogram monitor as a flexible, adjustable, and lightweight headband with 7 sensors-2 forehead sensors, 2 ear sensors, and 3 reference sensors. The headband incorporates a 3-axis accelerometer enabling head movement quantification. A variance analysis was used to compare the average head movement acceleration data between each group. Tulane University Medical Center, New Orleans, LA, an academic medical center and the principal teaching hospital for Tulane University School of Medicine. A total of following 19 participants were recruited for the study and stratified by surgical experience into novice (n = 6), intermediate (n = 9), and expert (n = 4) laparoscopy groups: 6 medical students, 9 urology residents (postgraduate years 1 to5), and 4 attending urologists, respectively. Analysis of the average acceleration rate of head movement showed statistically significant differences among groups on both the vertical axis (p = 0.006) and horizontal axis (p = 0.018) in the laparoscopic suturing task. This demonstrated the ability to distinguish between experts and novice laparoscopic surgeons. The average acceleration among groups did not demonstrate statistical significance on the

    Throughout the perioperative period, anesthetists and surgeons jointly provide care for patients. The advances in medicine and surgery, the practice of perioperative quality medicine and the recent application of enhanced recovery program after surgery have necessitated strengthening the place of each in its area of expertise while developing the spirit team and communication. Thus, alongside the surgeon who was once considered the head of the surgical team, the anesthetist's role has been to consolidate for the management of the surgical patient and had his spot empower themselves in the eye of the patient with the birth an own contract with the patient (due in particular to the obligation to preanesthetic consultation by the decree of December 5, 1994). This has led to a new division of responsibility between these actors: jurisprudence has abandoned the exclusive responsibility of the surgeon, devoted own responsibility of the anesthetist with a division (if any) of responsibility between the anesthetist and the surgeon.

    The Amundsen-Scott South Pole Research station located at the geographic South Pole, is the most isolated, permanently inhabited human outpost on Earth. Medical care is provided to station personnel by a non-surgeon crew medical officer (CMO). During the winter-over period from February to October, the station is isolated, with no incoming or outgoing flights due to severe weather conditions. In late June, four months after the station had closed for the austral winter, a 31 year old meteorologist suffered a complete rupture of his patellar tendon while sliding done an embankment. An evacuation was deemed to be too risky to aircrews due to the extreme cold and darkness. A panel of physicians from Massachusetts General Hospital, Johns Hopkins University and the University of Texas Medical Branch were able to assess the patient remotely via telemedicine and agreed that surgery was the only means to restore mobility and prevent long term disability. The lack of a surgical facility and a trained surgical team were overcome by conversion of the clinic treatment area, and intensive preparation of medical laypersons as surgical assistants. The non-surgeon CMO and CMO assistant at South Pole, were guided through the administration of spinal anesthetic, and the two-hour operative repair by medical consultants at Massachusetts General Hospital. Real-time video of the operative field, directions from the remote consultants and audio communication were provided by videoconferencing equipment, operative cameras, and high bandwidth satellite communications. In real-time, opening incision/exposure, tendon relocation, hemostatsis, and operative closure by the CMO was closely monitored and guided and by the remote consultants. The patient s subsequent physical rehabilitation over the ensuing months of isolation was also monitored remotely via telemedicine. This was the first time in South Pole s history that remote teleguidance had been used for surgery and represents a model for

    The aims of this study were to determine whether male vs. female oral and maxillofacial surgery (OMS) residents, academic surgeons (i.e., faculty members), and private practitioners in the U.S. differed in their general career satisfaction and job/professional satisfaction. Survey data were collected in 2011-12 from 267 OMS residents (response rate 55%), 271 OMS academic surgeons (response rate 31%), and 417 OMS private practitioners (response rates 13% web-based survey and 29% postal mail survey). The results showed that while the male vs. female OMS private practitioners and academic surgeons did not differ in their career satisfaction, the female residents had a lower career satisfaction than the male residents (on four-point scale with 4=most satisfied: 3.03 vs. 3.65; pcareer, and were more likely to consider a career change in the next five years than the male residents. While these male and female oral and maxillofacial surgeons in private practice and academia did not differ in their career and job satisfaction, the male and female residents differed significantly, with female residents reporting a significantly poorer career and job satisfaction than male residents. Future research needs to explore ways to improve career and professional satisfaction of female OMS residents.

    Self-directed violence (SDV), which includes suicidal ideation with and without intent, suicidal preparatory behaviors and attempts with and without harm, non-suicidal self-directed violence, and completed suicide, has been a rising concern in the military. Military shipboard personnel may represent a unique subset of this population due to the distinct nature of deployment stressors and embedded supports. As such, one might expect differences in the prevalence of SDV between this group and other active duty personnel, signifying a distinct operational impact. This study analyzed the prevalence of SDV among personnel assigned or deployed to U.S. Navy aircraft carriers, and examined whether occurrences varied by descriptors commonly identified in the literature (e.g., age, gender, marital status, pay grade/rank). This study also examined characteristics specific to life aboard a U.S. Navy aircraft carrier in order to better understand the issues particular to this population. Descriptive analyses and relative risk findings suggested similarities in demographic risk factors to the general military population, but also striking differences related to occupational specialty and assigned department. This study is the first to shed light on risk and protective factors relevant to shipboard personnel.

    To assess current habits for surgical hand preparation among veterinary surgical specialists and to compare data with current guidelines for hand asepsis techniques. Survey of veterinary surgical specialists. Diplomates of the American (ACVS) and European Colleges of Veterinary Surgeons (ECVS). An internet-based survey of hand preparation methods before surgical procedures was conducted of 1300 listed ACVS and ECVS Diplomates. A 42.6% response rate was obtained. Approximately, 80% of respondents use disinfecting soaps as a primary method for hand antisepsis. Of those, 81% use chlorhexidine-based scrubs and 7% use a neutral soap followed by a hydroalcoholic solution. Contrary to current recommendations of the World Health Organization and scientific evidence supporting use of hydro-alcoholic rubs for presurgical hand preparation, veterinary surgical specialists still use surgical scrub solutions containing disinfecting soaps. © Copyright 2011 by The American College of Veterinary Surgeons.

    The art and science of outcomes analysis, quality improvement, and patient safety continue to evolve, and cardiothoracic surgery leads many of these advances. The Society of Thoracic Surgeons (STS) National Database is one of the principal reasons for this leadership role, as it provides a platform for the generation of knowledge in all of these domains. Understanding these topics is a professional responsibility of all cardiothoracic surgeons. Therefore, beginning in January 2016, The Annals of Thoracic Surgery began publishing a monthly series of scholarly articles on outcomes analysis, quality improvement, and patient safety. This article provides a summary of the status of the STS National Database as of October 2016 and summarizes the articles about the STS National Database that appeared in The Annals of Thoracic Surgery 2016 series, "Outcomes Analysis, Quality Improvement, and Patient Safety."

    2016-06-01

    Concentric tube robots have potential for use in a wide variety of surgical procedures due to their small size, dexterity, and ability to move in highly curved paths. Unlike most existing clinical robots, the design of these robots can be developed and manufactured on a patient- and procedure-specific basis. The design of concentric tube robots typically requires significant computation and optimization, and it remains unclear how the surgeon should be involved. We propose to use a virtual reality-based design environment for surgeons to easily and intuitively visualize and design a set of concentric tube robots for a specific patient and procedure. In this paper, we describe a novel patient-specific design process in the context of the virtual reality interface. We also show a resulting concentric tube robot design, created by a pediatric urologist to access a kidney stone in a pediatric patient.

    Orthopaedic surgery has progressed over the years because of innovative work of pioneering orthopaedic surgeons; new developments in internal fixation techniques and implants codeveloped with the orthopaedic manufacturing industry have improved treatment greatly. This article analyzes and reviews the relationship of orthopaedic surgeons to the orthopaedic implant industry, analyzing three broad categories of the relationship: (1) physicians receiving gifts from industry; (2) the orthopaedic industry's financial support of educational and research endeavors of academic trauma and other centers; and (3) the relationship of the industry with innovators in the field of orthopaedic surgery by retainer fees, royalties, and stock options from industry. The ethical relationship requires: (1) putting the patient's concerns first above vested interests; (2) an awareness of a potential for abuse; and (3) a level of awareness of the relationship and the ability to explain and inculcate this relationship in the teaching program of young residents to maintain the high standards that have been set.

    The diagnosis and treatment of colorectal cancer is one of the main diseases of gastrointestinal surgeons. It is very important to master the adjuvant chemotherapy of colorectal cancer for gastrointestinal surgeons. In recent years, with the development of a number of clinical trials and the appearance of new drugs, fluorouracil combined with oxaliplatin had been established as the standard regimen of adjuvant chemotherapy for colorectal cancer. In the current guidelines, stage III( colon cancer is the indication for adjuvant chemotherapy, while stage II( colon cancer should receive adjuvant chemotherapy is uncertain. Unlike colon cancer, adjuvant therapy of rectal cancer is not evidence-based. Especially, the indication and duration of adjuvant chemotherapy for rectal cancer after neoadjuvant chemoradiotherapy remain controversial. Adjuvant therapy of colorectal cancer still needs further investigation.

    Various websites are dedicated to rating physicians. The goals of this study were to: (1) evaluate the prevalence of orthopedic surgeon ratings on physician rating websites in the United States and (2) evaluate factors that may affect ratings, such as sex, practice sector (academic or private), years of practice, and geographic location. A total of 557 orthopedic surgeons selected from the 30 most populated US cities were enrolled. The study period was June 1 to July 31, 2013. Practice type (academic vs private), sex, geographic location, and years since completion of training were evaluated. For each orthopedic surgeon, numeric ratings from 7 physician rating websites were collected. The ratings were standardized on a scale of 0 to 100. Written reviews were also collected and categorized as positive or negative. Of the 557 orthopedic surgeons, 525 (94.3%) were rated at least once on 1 of the physician rating websites. The average rating was 71.4. The study included 39 female physicians (7.4%) and 486 male physicians (92.6%). There were 204 (38.9%) physicians in academic practice and 321 (61.1%) in private practice. The greatest number of physicians, 281 (50.4%), practiced in the South and Southeast, whereas 276 (49.6%) practiced in the West, Midwest, and Northeast. Those in academic practice had significantly higher ratings (74.4 vs 71.1; P<.007). No significant difference based on sex (72.5 male physicians vs 70.2 female physicians; P=.17) or geographic location (P=.11) were noted. Most comments (64.6%) were positive or extremely positive. Physicians who were in practice for 6 to 10 years had significantly higher ratings (76.9, P<.01) than those in practice for 0 to 5 years (70.5) or for 21 or more years (70.7).

    For ease of use and to aid precision, left-handed instruments are invaluable to the left-handed surgeon. Although they exist, they are not available in many surgical centres. As a result, most operating theatre staff (including many left-handers) have little knowledge of their value or even application. With specific reference to cardiac surgery, this article addresses the ways in which they differ, why they are needed and what is required - with tips on use.

    2017-07-01

    Background Three-dimensional (3D) printing has developed as a revolutionary technology with the capacity to design accurate physical models in preoperative planning. We present our experience in surgeon-based design of 3D models, using home 3D software and printing technology for use as an adjunct in vascularized bone transfer. Methods Home 3D printing techniques were used in the design and execution of vascularized bone flap transfers to the upper extremity. Open source imaging software was used to convert preoperative computed tomography scans and create 3D models. These were printed in the surgeon's office as 3D models for the planned reconstruction. Vascularized bone flaps were designed intraoperatively based on the 3D printed models. Results Three-dimensional models were created for intraoperative use in vascularized bone flaps, including (1) medial femoral trochlea (MFT) flap for scaphoid avascular necrosis and nonunion, (2) MFT flap for lunate avascular necrosis and nonunion, (3) medial femoral condyle (MFC) flap for wrist arthrodesis, and (4) free fibula osteocutaneous flap for distal radius septic nonunion. Templates based on the 3D models allowed for the precise and rapid contouring of well-vascularized bone flaps in situ, prior to ligating the donor pedicle. Conclusions Surgeon-based 3D printing is a feasible, innovative technology that allows for the precise and rapid contouring of models that can be created in various configurations for pre- and intraoperative planning. The technology is easy to use, convenient, and highly economical as compared with traditional send-out manufacturing. Surgeon-based 3D printing is a useful adjunct in vascularized bone transfer.

    There is little information available on the results of radial and astigmatic keratotomy surgery that is performed by beginning refractive surgeons. A retrospective review of all refractive keratotomies performed by Corneal Fellows in the University of California, Los Angeles, Department of Ophthalmology between October 1985 and October 1991 was performed. Data from all eyes with at least 3 months of follow-up were analyzed. Visual acuity, refractive error, and complication rates were compared with published case series. The mean preoperative spherical equivalent for the 79 eyes analyzed was -3.97 diopters (D) (range, -0.75 to -8.50 D). The mean postoperative spherical equivalent was -0.44 D (range, +1.50 to -3.88 D). The postoperative spherical equivalent was within 1.00 D of emmetropia in 85% of eyes, and uncorrected visual acuity was 20/40 or better in 94% of eyes. There were no vision-threatening complications. No patient lost more than one line of best-corrected visual acuity. Radial and astigmatic keratotomies that are performed by beginning refractive surgeons in a supervised setting can be safe and effective procedures with results comparable with those obtained by experienced refractive surgeons.

    2010-08-01

    Full Text Available Abstract Introduction Although the causes of sarcoidosis are still unknown, past and current studies have provided evidence that this disease may be associated with occupational exposure to specific environmental agents. We describe a case of sarcoidosis in a dental surgeon with long exposure to inorganic dusts. To the best of our knowledge, this is the first report of this kind in the literature. Case presentation At the beginning of 2000, a 52-year-old Caucasian man, who worked as a dental surgeon, presented with shortness of breath during exercise, cough and retrosternal pain. After diagnosis of sarcoidosis, a scanning electronic microscopy with X-ray microanalysis of biopsy specimens was used in order to determine whether the disease could be traced to an occupational environmental agent. Results showed the presence of inorganic dust particles within sarcoidotic granulomas, and demonstrated that the material detected was identical to that found in a powder used by our patient for several years. Conclusions Although these results cannot be considered as definitive proof, they do however provide strong evidence that this disease may be associated with material used by dental surgeons.

    This study was designed to assess the importance of communication between surgeons and radiographers in the operation of image intensifiers during orthopaedic surgery. This study was designed and conducted as single-centre, observational study. Fifteen medical officers and 15 radiographers were involved in this study. Each of the 15 radiographers was assigned to a medical officer. The 15 pairs were then each given a task to simulate achieving 'perfect circles' on fluoroscopy for distal locking of an intramedullary nail.

    Oral and maxillofacial surgeons traditionally have musculoskeletal pain. The aim of this study was to determine the postural preferences of oral and maxillofacial surgeons and their effect on musculoskeletal pain. The authors designed and implemented a cross-sectional study. The association of demographic characteristics with postural preferences and use of loupes was explored. Then, the relation of demographic characteristics, postural preferences, and use of loupes to painful musculoskeletal complaints was analyzed. Contingency analysis was used to compare participants' responses and multiple logistic regression analysis was used to identify relevant predictor variables. The sample was composed of 153 oral and maxillofacial surgeons, of which 32% indicated that they had ever had pain attributable to their practice that lasted longer than 2 weeks. Practitioners reported neck and back pain as being most common. Eighty-four percent of practitioners stood for extractions and placement of implants. Those who stood did so for visibility. Practitioners who sat indicated they did so for orthopedic reasons (P < .001). Thirty-one percent of practitioners indicated loupes use. Those who used loupes were more likely to report pain (P = .022). Most respondents stood and did not use loupes. Those who did use loupes were more likely to report pain. Those who stood did so for visibility; those who sat did so for orthopedic reasons. Almost one third of respondents reported pain lasting at least 2 weeks during practice. Copyright © 2017.

    Full Text Available Burn traumas are a type of trauma that causes adverse changes in all the functions of the organism. Multi-disciplinary approaches are of great importance in the treatment of burn traumas. Among those involved in the treatment of burns are people of many branches such as surgeons, infection specialists, rehabilitation specialists, psychiatrists, and nurses. And there is a need for a single specialist in charge to coordinate the disciplines in the stage of organizing to treatment. The person to take on this task is often a surgeon specialized in burns. Research has shown that auxiliary personnel involved in burn treatment in Turkey are in need of training on up-to-date information. The surgeon in charge should actively participate in research and training activities, and train the relevant personnel through knowledge transfer so that burn treatment could remain effective in the light of current developments, which would be the fundamental way for burn centers to take their technique- and skill-based practices further.

    2006-07-01

    The traditional didactic approach to improving the skill set of surgeons has been shown to have minimal impact. Surgeons, like other adults, learn best by doing, by practicing what they do. and by challenging themselves to take on increasingly difficult scenarios. To be effective, surgical practice requires deconstruction of a procedure into key elements, each of which is repeated until optimal results are achieved before moving on to the next element. Given the multifactorial nature of a procedure such as minimally invasive surgery for total knee arthroplasty, surgeons need to introduce incremental changes into their operating environment to allow for realistic self-assessment during postoperative self-debriefing. One technique, visualization, can be used for virtual practice. In the future, surgical simulators may allow for true virtual practice as well as systematic recording of results. However, psychomotor skills are only one component of surgical success. Intuition and innovation are also key, but these components are more difficult to teach and to learn. The key ingredient to successful practice and ultimate self-improvement in surgery, as in other pursuits in life, is that a person be self-motivated and competitive and have a strong desire to improve coupled with appropriate practice routines that can lead to improvement.

    Full Text Available Although exact statistics are not available, Indian plastic surgeons see around 7,00,000-8,00,000 burn admissions annually with around 10,00,000 cleft patients yet to be operated. In spite of this voluminous load, India does not have national health programs for the various deformities Indian plastic surgeons typically treat. As Plastic Surgeons, it is our social responsibility to treat these patients and bring ′ muskan ′ (smile in Hindi back into their lives. Project Muskan was initiated as an innovative model for targeting these patients and is probably one of its kind in the field of plastic surgery in our country. It is unique because it is a perfect collaboration of government institutions, a Non Government Organization (NGO, and cooperative sectors providing free health care at the doorstep. Identification of the patients was done with the help of the extensive milk dairy network in the state of Gujarat. Provision of transport and other facilities was done by the NGOs and quality health care provision was taken care of by the government hospital. Project Muskan started from a single village but now covers around 3000 villages and tribal areas of Gujarat. It is a system that can be easily reproducible in all hospitals and has reestablished the faith of the common man in government institutes.

    There has been a long-standing desire to implement a multi-institutional, multispecialty program to address surgical quality improvement for children. This report documents results of the initial phase of the American College of Surgeons National Surgical Quality Improvement Program Pediatric. From October 2008 to December 2009, patients from 4 pediatric referral centers were sampled using American College of Surgeons National Surgical Quality Improvement Program methodology tailored to children. A total of 7,287 patients were sampled, representing general/thoracic surgery (n = 2,237; 30.7%), otolaryngology (n = 1,687; 23.2%), orthopaedic surgery (n = 1,367; 18.8%), urology (n = 893; 12.3%), neurosurgery (n = 697; 9.6%), and plastic surgery (n = 406; 5.6%). Overall mortality rate detected was 0.3% and 287 (3.9%) patients had postoperative occurrences. After accounting for demographic, preoperative, and operative factors, occurrences were 4 times more likely in those undergoing inpatient versus outpatient procedures (odds ratio [OR] = 4.71; 95% CI, 3.01-7.35). Other factors associated with higher likelihood of postoperative occurrences included nutritional/immune history, such as preoperative weight loss/chronic steroid use (OR = 1.49; 95% CI, 1.03-2.15), as well as physiologic compromise, such as sepsis/inotrope use before surgery (OR = 1.68; 95% CI, 1.10-1.95). Operative factors associated with occurrences included multiple procedures under the same anesthetic (OR = 1.58; 95% CI, 1.21-2.06) and American Society of Anesthesiologists classification category 4/5 versus 1 (OR = 5.74; 95% CI, 2.94-11.24). Specialty complication rates varied from 1.5% for otolaryngology to 9.0% for neurosurgery (p Pediatric has the potential to identify outcomes of children's surgical care that can be targeted for quality improvement efforts.

    The Epic electronic health record (EHR) platform supports structured data entry systems (SDES), which allow developers, with input from users, to create highly customized patient-record templates in order to maximize data completeness and to standardize structure. There are many potential advantages of using discrete data fields in the EHR to capture data for secondary analysis and epidemiological research, but direct data acquisition from clinicians remains one of the largest obstacles to leveraging the EHR for secondary use. Physician resistance to SDES is multifactorial. A 35-item questionnaire based on Unified Theory of Acceptance and Use of Technology, was used to measure attitudes, facilitation, and potential incentives for adopting SDES for clinical documentation among 25 pediatric specialty physicians and surgeons. Statistical analysis included chi-square for categorical data as well as independent sample t-tests and analysis of variance for continuous variables. Mean scores of the nine constructs demonstrated primarily positive physician attitudes toward SDES, while the surgeons were neutral. Those under 40 were more likely to respond that facilitating conditions for structured entry existed as compared to the two older age groups (p = .02). Pediatric surgeons were significantly less positive than specialty physicians about SDES effects on Performance (p = .01) and the effect of Social Influence (p = .02); but in more agreement that use of forms was voluntary (p = .02). Attitudinal differences likely reflect medical training, clinical practice workflows, and division specific practices. Identified resistance indicate efforts to increase SDES adoption should be discipline-targeted rather than a uniform approach.

    Rising health care costs, decreasing reimbursement rates, and changes in American health care are forcing physicians to become increasingly business-minded. Both academic and private plastic surgeons can benefit from being educated in business principles. The authors conducted a systematic review to identify existing business curricula and integrated a business principles curriculum into residency training. The authors anonymously surveyed their department regarding perceived importance of business principles and performed a systematic literature review from 1993 to 2013 using PubMed and Embase to identify residency training programs that had designed/implemented business curricula. Subsequently, the authors implemented a formal, quarterly business curriculum. Thirty-two of 36 physicians (88.9 percent; 76.6 percent response rate) stated business principles are either "pretty important" or "very important" to being a doctor. Only 36 percent of faculty and 41 percent of trainees had previous business instruction. The authors identified 434 articles in the systematic review: 29 documented formal business curricula. Twelve topics were addressed, with practice management/administration (n = 22) and systems-based practice (n = 6) being the most common. Four articles were from surgical specialties: otolaryngology (n = 1), general surgery (n = 2), and combined general surgery/plastic surgery (n = 1). Teaching formats included lectures and self-directed learning modules; outcomes and participant satisfaction were reported inconsistently. From August of 2013 to June of 2015, the authors held eight business principles sessions. Postsession surveys demonstrated moderately to extremely satisfied responses in 75 percent or more of resident/fellow respondents (n = 13; response rate, 48.1 percent) and faculty (n = 9; response rate, 45.0 percent). Business principles can be integrated into residency training programs. Having speakers familiar with the physician audience and a

    The diagnosis of tumors and pseudotumors depends on three pillars: the clinician, the radiologist, and the pathologist. The first two can establish a presumptive diagnosis on the basis of the clinical presentation and findings on complementary tests, whereas the pathologist will have to reach the definitive diagnosis after analyzing the biopsy specimens. Obviously, the clinician and radiologist should reach a consensus regarding the diagnostic orientation; however, for this to happen there must be a relationship between the two professionals and they must work together for the benefit of the patient. Orthopedic surgeons, like any other group of specialists, would like to have radiologists working in their own center who are dedicated to the organ/system they treat, in this case the locomotor apparatus, and who can provide them with their opinion about the different images obtained. This point is very important and especially so for tumors, because this type of disease is uncommon and few specialists are dedicated to it. For this reason, when faced with a lesion that has the characteristics of a tumor, orthopedic surgeons would like radiologists to give the most accurate description of the images as possible, defining the characteristics of benignity or malignancy of the process as well as indicating the risk of fracture in a metastatic lesion. On the other hand, orthopedic surgeons would ask for a clear and comprehensible description of the images obtained in complementary tests, because orthopedic surgeons have less experience in this type of images and they are often difficult to interpret. Another aspect that is often mentioned in discussions among orthopedic surgeons is the importance of having a radiology department that performs interventional procedures. Radiologists that perform interventional procedures can facilitate our work very much, both in the diagnosis and in the treatment of certain bone tumors. Finally, we would like to stress the importance of

    Analyses of volume-outcome relationships in adult surgery have found that hospital and physician characteristics affect patient outcomes, such as length of stay, hospital charges, complications, and mortality. Similar investigations in children's surgical specialties are fewer in number, and their conclusions are less clear. To review the evidence regarding surgeon or hospital experience and their influence on outcomes in children's surgery. A MEDLINE and EMBASE search was conducted for English-language studies published from January 1, 1980, through April 13, 2012. Titles and abstracts were screened in a standardized manner by 2 reviewers. Studies selected for inclusion had to use a measure of hospital or surgeon experience as a predictor variable and had to report postoperative outcomes as dependent response variables. Included studies were reviewed with regard to methodologic quality, and study results were extracted. Sixty-three studies were reviewed. Significant heterogeneity was detected in exposure definitions, outcome measures, and risk adjustment, with the greatest heterogeneity seen in appendectomy studies. Various exposure levels were examined: hospital level in 48 (68%) studies, surgeon level in 11 (17%), and both in 9 (14%). Nineteen percent of studies did not adjust for confounding, and 57% did not adjust for sample clustering. The most consistent methods and reproducible results were seen in the pediatric cardiac surgical literature. Forty-nine studies (78%) showed positive correlation between experience and most primary outcomes, but differences in outcomes and exposure definitions made comparisons between studies difficult. In general, hospital-level factors tended to correlate with outcomes for high-complexity procedures, whereas surgeon-level factors tended to correlate with outcomes for more common procedures. Data on experience-related outcomes in children's surgery are limited in number and vary widely in methodologic quality. Future studies

    Graduating military preliminary interns are often required to fill flight surgeon billets. General surgery preliminary interns get experience evaluating surgical and trauma patients, but receive very little training in primary care and flight medicine. At a joint military and civilian training program, we developed a supplemental curriculum to help transition our interns into flight medicine. From 2013 to 2016, we developed a lecture series focused on aerospace medicine, primary care, and specialty topics including dermatology, ophthalmology, orthopedics, pediatrics, psychiatry, and women's health. During the 2016 iteration attended by 10 interns, pre- and post-participation 10-item Likert scale surveys were administered. Questions focused on perceived preparedness for primary care role and overall enthusiasm for flight medicine. Open-ended surveys from 2013 to 2016 were also used to gauge the effect of the curriculum. The composite number of agreement responses (indicating increased comfort with presented material) increased 63% after course completion. Disagreement responses and neutral responses decreased 78% and 30%, respectively. Open-ended surveys from 14 participants showed an overall positive impression of the curriculum with all indicating it aided their transition to flight medicine. Survey responses indicate an overall perceived benefit from participation in the curriculum with more confidence in primary care topics and improved transition to a flight medicine tour. This model for supplemental aerospace medicine and primary care didactics should be integrated into any residency program responsible for training military preliminary interns who may serve as flight surgeons.

    Fenestrated endovascular aneurysm repair (FEVAR) allows endovascular treatment of thoracoabdominal and juxtarenal aneurysms previously outside the indications of use for standard devices. However, because of considerable device costs and increased procedure time, FEVAR is thought to result in financial losses for medical centers and physicians. We hypothesized that surgeon leadership in the coding, billing, and contractual negotiations for FEVAR procedures will increase medical center contribution margin (CM) and physician reimbursement. At the UMass Memorial Center for Complex Aortic Disease, a vascular surgeon with experience in medical finances is supported to manage the billing and coding of FEVAR procedures for medical center and physician reimbursement. A comprehensive financial analysis was performed for all FEVAR procedures (2011-2015), independent of insurance status, patient presentation, or type of device used. Medical center CM (actual reimbursement minus direct costs) was determined for each index FEVAR procedure and for all related subsequent procedures, inpatient or outpatient, 3 months before and 1 year subsequent to the index FEVAR procedure. Medical center CM for outpatient clinic visits, radiology examinations, vascular laboratory studies, and cardiology and pulmonary evaluations related to FEVAR were also determined. Surgeon reimbursement for index FEVAR procedure, related adjunct procedures, and assistant surgeon reimbursement were also calculated. All financial analyses were performed and adjudicated by the UMass Department of Finance. The index hospitalization for 63 FEVAR procedures incurred $2,776,726 of direct costs and generated $3,027,887 in reimbursement, resulting in a positive CM of $251,160. Subsequent related hospital procedures (n = 26) generated a CM of $144,473. Outpatient clinic visits, radiologic examinations, and vascular laboratory studies generated an additional CM of $96,888. Direct cost analysis revealed that grafts

    Full Text Available Peripheral nerve injuries remain a challenge for reconstructive surgeons with many patients obtaining suboptimal results. Understanding the level of injury is imperative for successful repair. Current methods for distinguishing healthy from damaged nerve are time consuming and possess limited efficacy. Confocal laser endomicroscopy (CLE is an emerging optical biopsy technology that enables dynamic, high resolution, sub-surface imaging of live tissue. Porcine sciatic nerve was either left undamaged or briefly clamped to simulate injury. Diluted fluorescein was applied topically to the nerve. CLE imaging was performed by direct contact of the probe with nerve tissue. Images representative of both damaged and undamaged nerve fibers were collected and compared to routine H&E histology. Optical biopsy of undamaged nerve revealed bands of longitudinal nerve fibers, distinct from surrounding adipose and connective tissue. When damaged, these bands appear truncated and terminate in blebs of opacity. H&E staining revealed similar features in damaged nerve fibers. These results prompt development of a protocol for imaging peripheral nerves intraoperatively. To this end, improving surgeons' ability to understand the level of injury through real-time imaging will allow for faster and more informed operative decisions than the current standard permits.

  11. Health care delivery and the training of surgeons.

    Most countries have mastered the art of cost containment by global budgeting for public expenditure. It is not as yet clear whether the other option, managed care, or managed competition will accomplish cost control in America. Robert Evans, a Canadian health care expert, remains skeptical. He says, "HMO's are the future, always have been and always will be." With few exceptions, the amount spent on health care is not a function of the system but of the gross domestic product per person. Great Britain is below the line expected for expenditure, which may be due to truly impressive waiting lists. The United States is above the line, which is probably related to the overhead costs to administer the system and the strong demand by patients for prompt and highly sophisticated diagnostic measures and treatments. Canada is on the line, but no other country has subscribed to the Canadian veto on private insurance. Reform or changes are occurring in all countries and will continue to do so. For example, we are as terrified of managed care in Canada as you are of our brand of socialized insurance. We distrust practice by protocol just as you abhor waiting lists. From my perspective as a surgeon, I envision an ideal system that would cover all citizens, would maintain choice of surgeon by patients, would provide mechanisms for cost containment that would have the active and continuous participation of the medical profession, and would provide for research and development. Any alteration in health care delivery in the United States that compromises biomedical research and development will be a retrogressive, expensive step that could adversely affect the health of nations everywhere. Finally, a continuing priority of our training programs must be to ensure that the surgeon participating in this system continues to treat each patient as an individual with concern for his or her own needs.

    Hemophilia will be encountered in the oral and maxillofacial surgeon's office. A thorough understanding of hemophilia is necessary to safely care for these patients. One must understand the severity of the patient's hemophilia as well as whether or not inhibitors are present. The patient's surgical management will be influenced by these two factors. In addition to the possible need to transfuse factors or desmopressin, special care must be taken perioperatively to avoid bleeding complications.

    In 1980, posttraumatic stress disorder (PTSD) officially became classified as an anxiety disorder in the Diagnostic and Statistical Manual of Mental Disorders, 3rd edition. Since then, there has been increasing recognition that PTSD is a prevalent disorder that may have significant impact on the quality of life for survivors of traumatic events. More recently, methodologically sound research has begun to provide important insight into this disorder. The following review serves to provide the trauma surgeons information on PTSD in terms of its diagnosis, prevalence, risk factors, treatment strategies, and outcomes, with the goal of minimizing the sequelae of PTSD and maximizing postinjury quality of life.

    2005-08-01

    Improvised explosive devices have created a new class of casualties that presents a unique surgical challenge for oral and maxillofacial surgeons. The injury pattern and severity are different from those seen in conventional trauma patients. Because of battlefield circumstances, patients are sometimes delayed significantly in their transport to a trauma center, and they frequently arrive at a trauma center with hypotension, hypothermia, and acidosis. Definitive care is delayed while the hemodynamic status and life-threatening injuries are stabilized. Hospital triage protocols must be well established in advance to prepare a timely response to the mass casualty event. Proper resource use is an ever-evolving challenge for hospital staff during these times.

    Motion pictures are made to entertain and enlighten people, but they are viewed differently by different people. What one considers to be a tearjerker may induce giggles in another. We have gained added interest in this because our professional pictures contain plastic surgery in their venue. We have recently reviewed 21 motion pictures that were made from 1928 to 2006 and that includes plastic surgical procedures in their content. As a habit, we tried to analyze them from a surgical point of view. About one third (35.7%) of the patients were criminals, whereas 14.3% of them were spies. One third of the procedures were done by illegitimate "surgeons," whereas a quarter of the procedures (25%) were performed by renowned surgeons. Surgeons who were in love with the patients did the rest (25%) of the operations. The complication rate was 14.3%; the surgery was successful in 85.7% of cases, but were the patients happy with the results? This was not the case in the movies. Only 7.7% were happy; 14.5 % of them were eminently unhappy. Why the discrepancy? It is difficult to analyze the minds of the people in the film, but considering that the majority of the characters in the films were rather unsavory, one may deduce that a crooked mind functions differently. Motion pictures have advanced greatly in the past several decades with the advent of improved mechanical and electronic devices, and plastic surgery as also advanced in tandem. This surgical field has become a common procedure in our daily life. It is readily available and mostly painless. However, the public sees it in only one way, that is, that the performing physicians are highly compensated. Very few consider the efforts and the suffering that accompanies each and every surgical procedure as it is performed. Perhaps, it is too much to hope for a day that will come when we will see a film that portrays the mental anguish that accompanies each and every procedure the plastic surgeon makes.

    As surgeons progress through their careers, they are often entrusted with leadership roles in administration, education, research, and patient management. Insights into one's own personality type and leadership style as well as an understanding of the value of emotional intelligence are critical for success. Knowledge of group dynamics and team leading; networking; techniques in leading, changing, and innovation; as well as proficiency in negotiation and conflict resolution are also essential to the development of leadership skills.

This paper presents a pre-operative review and a conceptual framework for intra-operative planning for Mohs micrographic surgery and reconstruction. The key concepts presented are based on a series of (1) reviews regarding clinically significant points aimed at improving outcomes for reconstructive surgery, (2) anatomical dissections of fresh frozen cadavers, and (3) surgical experience of the authors. Basic anatomical concepts have been assimilated, surgically evaluated and re-directed toward the dermatologic surgeon in the hope that improved anatomic competence will reduce surgical hesitance. © 2015 Wiley Periodicals, Inc.

    The Patient Protection and Affordable Care Act, sometimes referred to as Obamacare, was signed into law on March 23, 2010. It represents the most extensive overhaul of the country's health care system since the passage of Medicare and Medicaid in 1965. The Affordable Care Act has two goals. The first goal is to reduce the uninsured population in the United States. Key elements to covering the uninsured include the following: (1) expanding Medicaid coverage for low-income individuals and (2) establishing health insurance marketplaces for moderate-income individuals with subsidies and tax cuts in an effort to make health insurance more affordable. The second goal of the Affordable Care Act is to address concerns about quality and the overall cost of U.S. health care. It is imperative that plastic surgeons thoroughly understand the impact that the Affordable Care Act will undoubtedly have on the country, on our patients, and on our clinical practices. Plastic surgery will see many changes in the future. This will include an overall increase in the number of insured patients, a push toward joining accountable care organizations, and a shift in payment systems to bundled reimbursement for episodes of care. In this article, the authors describe how these changes are likely to occur and what plastic surgeons must do to be part of the change.

    The aim of this study was to compare double gloves (DGs) with single gloves (SGs) during orthopedic and trauma surgery in prevention of blood contact between patients and surgeons. DGs and SGs were collected after orthopedic operations, tested for size, site, and number of perforations. Medical records were reviewed for age, sex, type of operation, duration, and postoperative wound infection. Data were compared using t-test with level of statistical significance at P < 0.05. Five hundred seven operations yielded 1204 DGs and 830 pairs SGs. In DGs, perforations were detected in 220 outer glove and 39 inner glove (10.7%). In SGs, 226 perforations were detected (13.3%). The incidence of perforations in inner gloves of the double indicator glove was 1.6% (P < 0.001). During surgery, perforations were recognized in DGs in 67% compared with 12% in SGs (P < 0.005). This study confirms that DGs form an efficient barrier between patients and surgeons.

    Arthur Rainsford Mowlem, the junior of the 'big four' plastic surgeons, with Harold Delf Gillies, Thomas Pomfret Kilner and Archibald Hector McIndoe, came to prominence managing casualties of the Second World War. Rainsford Mowlem's ancestor was John Mowlem, the creator of the construction firm. Rainsford worked his passage to the United Kingdom from New Zealand in 1927 and did not return to New Zealand but retired at the age of 60 to enjoy 23 more years in Spain. He was the driving force between 1934 and 1939 at the Plastic Surgery Unit at St James's Hospital, Balham, and instigated the North London Plastic Surgery Unit at Hill End, St Albans, from 1939 to 1953 and subsequently developed the Unit after moving to Mount Vernon Hospital, Northwood, Middlesex. After successfully hosting the International Meeting of Plastic Surgeons in London in 1959, he received recognition and honours in America but soon afterwards he surprised colleagues by retiring in 1962. Despite his significant contributions, he did not receive national honours but his life outside surgery was active including Trusteeship of the Mowlem Estate at Swanage in Dorset for 40 years.

    With technological improvements in body armour and increasing use of improvised explosive devices, it is the injuries to head, face and neck are the cause for maximum fatalities as military personnel are surviving wounds that would have otherwise been fatal. The priorities of battlefield surgical treatment are to save life, eyesight and limbs and then to give the best functional and aesthetic outcome for other wounds. Modern day battlefields pose unique demands on the deployed surgical teams and management of head and neck wounds demands multispecialty approach. Optimal result will depend on teamwork of head and neck trauma management team, which should also include otolaryngologist. Data collected by various deployed HFN surgical teams is studied and quoted in the article to give factual figures. Otorhinolaryngology becomes a crucial sub-speciality in the care of the injured and military otorhinolaryngologists need to be trained and deployed accordingly. The otolaryngologist's clinical knowledge base and surgical domain allows the ENT surgeon to uniquely contribute in response to mass casualty incident. Military planners need to recognize the felt need and respond by deploying teams of specialist head and neck surgeons which should also include otorhinolaryngologists.

    The appropriate diagnosis and treatment of bone tumors requires close collaboration between different medical specialists. Imaging plays a key role throughout the process. Radiographic detection of a bone tumor is usually not challenging. Accurate diagnosis is often possible from physical examination, history, and standard radiographs. The location of the lesion in the bone and the skeleton, its size and margins, the presence and type of periosteal reaction, and any mineralization all help determine diagnosis. Other imaging modalities contribute to the formation of a diagnosis but are more critical for staging, evaluation of response to treatment, surgical planning, and follow-up.When necessary, biopsy is often radioguided, and should be performed in consultation with the surgeon performing the definitive operative procedure. CT is optimal for characterization of the bone involvement and for evaluation of pulmonary metastases. MRI is highly accurate in determining the intraosseous extent of tumor and for assessing soft tissue, joint, and vascular involvement. FDG-PET imaging is becoming increasingly useful for the staging of tumors, assessing response to neoadjuvant treatment, and detecting relapses.Refinement of these and other imaging modalities and the development of new technologies such as image fusion for computer-navigated bone tumor surgery will help surgeons produce a detailed and reliable preoperative plan, especially in challenging sites such as the pelvis and spine.

    Introduction Our nation suffers from a shortage in surgeons. This deficiency must be addressed at the medical student level. Increasing faculty and resident interaction with junior students augments surgical interest. Our surgical interest group has recently redefined its role to address these concerns. Methods A multifocal approach has been implemented to increase interest in the surgical specialties. Each academic year, senior students recruit first and second year students to our group to establish early exposure. Members receive didactic presentations from surgical faculty, addressing various topics, on a biweekly basis. In addition, scrubbing, knot-tying, and suturing workshops address technical skills throughout the semester. Membership and match data were collated and analyzed. Results Over the past 5 years, the enrollment in the student interest group increased significantly from 112 to 150. Accordingly, we have observed a parallel increase in the number of students who have successfully matched into surgical residencies. A record number of students (37) from the class of 2013 matched into surgical specialties, representing an 85% increase over the last decade. After creating bylaws and electing societal officers, the group has been recognized by the school's Student Council and given financial support. At present, the group is fiscally solvent with support from the institution, surgery department, and faculty. Conclusion As the demand for surgeons increases so too does the need to increase student interest in surgery. Our school has been successful because of our surgical interest group, and we encourage other schools to adopt a similar approach. © The Author(s) 2016.

    2016-01-01

    Hip resurfacing has been proposed as an alternative to traditional total hip arthroplasty in young, active patients. Much has been learned following the introduction of metal-on-metal resurfacing devices in the 1990s. The triad of a well-designed device, implanted accurately, in the correct patient has never been more critical than with these implants. Following Food and Drug Administration approval in 2006, we studied the safety and effectiveness of one hip resurfacing device (Birmingham Hip Resurfacing) at our hospital in a large, single-surgeon series. We report our early to mid-term results in 1333 cases followed for a mean of 4.3 years (2 to 5.7) using a prospective, observational registry. The mean patient age was 53.1 years (12 to 84); 70% were male and 91% had osteoarthritis. Complications were few, including no dislocations, no femoral component loosening, two femoral neck fractures (0.15%), one socket loosening (0.08%), three deep infections (0.23%), and three cases of metallosis (0.23%). There were no destructive pseudotumours. Overall survivorship at up to 5.7 years was 99.2%. Aseptic survivorship in males under the age of 50 was 100%. We believe this is the largest United States series of a single surgeon using a single resurfacing system.

  7. [What rhinoplasty surgeons should know about body dysmorphic disorder (BDD)].

    2014-08-01

    Body dysmorphic disorder (BDD) is a psychiatric disorder characterized by an excessive concern with a non-existing or slight defect in physical appearance. BDD patients frequently show impaired judgment regarding the psychiatric origin of their concerns and often seek aesthetic treatment to resolve their appearance concerns. The central position of the nose in the face makes the nose one of the most common areas of concern in patients with BDD. Thus, aesthetic rhinoplasty is suspected to be one of the most frequently requested and performed surgical procedures in this population. However, there is a growing consensus that BDD should be considered a contraindication for aesthetic rhinoplasty, as favourable outcome is unlike [1-5]. In order to prevent patients from undergoing unsatisfying surgery and in the context of the increasing importance of medico-legal arguments, the rhinoplasty surgeon should be familiar with BDD. This article provides a focused review of issues pertaining to BDD that are relevant to the rhinoplasty surgeon. © Georg Thieme Verlag KG Stuttgart · New York.

    Mobile phone applications (Apps) have become a vital assistant to medical personnel in today's technologically advanced era. The utility of Apps with case logbook capabilities has not yet been explored. To assess and evaluate all currently available surgical and procedural case logbook Apps. A comprehensive search was conducted in April 2015 on the Android Play Store, iTunes (Apple App Store, iOS), and BlackBerry World for surgical and/or procedural logbooks. The search terms'surgical logbook', 'logbook', 'procedure logbook' and 'surgical log' were used. Apps which could not be utilized as a surgical/procedural logbook were excluded. Each App was individually assessed and rated using preset criteria, by the unit consultant, registrars, and medical officer. In total, 2 740 Apps were assessed. After applying our exclusion criteria, only 16 Apps were relevant, and 11 suitable for critical review. Data sizes ranged from 510Kb to 12.2Mb. Costing of the Apps ranged from ZAR 0.00 to ZAR 105.32. The overall study scores revealed the following top five rated Apps: Surgical Logbook by Surgilog; Surgeon Logbook Pro; Surgery Notebook, Surgical Logbook, and Universal Logbook. The current mobile Apps available are efficient in replacing traditional case logbooks. The use of the 'Smart Logbook' may become common practice in the life of the modern-day surgeon.

  9. A new model for the global biogeochemical cycle of carbonyl sulfide - Part 1: Assessment of direct marine emissions with an oceanic general circulation and biogeochemistry model

    The global budget of tropospheric carbonyl sulfide (OCS) is believed to be at equilibrium because background air concentrations have remained roughly stable over at least the last decade. Since the uptakes of OCS by leaves (associated to photosynthesis) and soils have been revised significantly upwards recently, an equilibrated budget can only be obtained with a compensatory source of OCS. It has been assumed that the missing source of OCS comes from the low latitude ocean, following the incident solar flux. The present work uses parameterizations of major production and removal processes of organic compounds in the NEMO-PISCES Ocean General Circulation and Biogeochemistry Model to assess the marine source of OCS. In addition, the OCS photo-production rates computed with the NEMO-PISCES model were evaluated independently using UV absorption coefficient of chromophoric dissolved organic matter (derived from satellite ocean color) and apparent quantum yields available in the literature. Our simulations show global direct marine emissions of COS in the range of 573-3997 Gg S yr-1, depending mostly on the quantification of the absorption rate of chromophoric dissolved organic matter. The high estimates on that range are unlikely, as they correspond to a formulation that most likely overestimate photo-production process. Low and medium (813 Gg S yr-1) estimates derived from the NEMO-PISCES model are however consistent spatially and temporally with the suggested missing source of Berry et al. (2013), allowing thus to close the global budget of OCS given the recent estimates of leaf and soil OCS uptakes.

  16. Three-port colectomy: reduced port laparoscopy for general surgeons. A single center experience.

    Science.gov (United States)

    Cocorullo, Gianfranco; Tutino, Roberta; Falco, Nicolò; Salamone, Giuseppe; Gulotta, Gaspare

    Le resezioni coliche laparoscopiche sia per patologie benigne che maligne sono state investigate da importanti RCT che ne hanno dimostrato la sovrapponibilità alla tecnica open convenzionale. La laparoscopia con un numero ridotto di trocar ha da quel momento trovato ampio sviluppo nell’ottica di massimizzare i benefici della mini-invasività. Proponiamo un’analisi dei nostri risultati nell’utilizzo della tecnica three-port nella emicolectomia sinistra attraverso un confronto con la classica resezione laparoscopica con quattro/ cinque accessi. Come è noto i laparoceli si sviluppano maggiormente su incisioni mediane mentre non vi è differenza tra lo sviluppo di questi dopo tecnica open o laparoscopica. Nell’ottica della chirurgia a numero ridotto di accessi, la tecnica single-port sembra dare vantaggi di minor traumatismo ma ciò a costo di aumentate difficoltà di esecuzione, aumento dei tempi operatori e dell’utilizzo di strumenti per lo più dedicati, con incisioni ombelicali che possono superare i 5 cm. Le resezioni coliche three port consentono di ridurre il numero di accessi e dunque delle complicanze a questi correlate con l’utilizzo di strumentazione standard e la possibilità di esecuzione su larga scala da parte di ogni chirurgo. L’analisi che abbiamo eseguito ha dimostrato nella nostra serie una riduzione dei tempi operatori nella tecnica three port e ciò può essere dovuto all’inserimento dei trocar addizionali ed al loro controllo ma soprattutto alla possibilità/ necessità del chirurgo esperto di essere meno influenzato da fattori quali una equipe non dedicata. Non sono stati evidenziati vantaggi nella riduzione della degenza operatoria. Il tasso di conversione è stato maggiore nella tecnica a ridotto numero di accessi, questo è possibile sia un bias legato alle conversioni precoci prima del posizionamento di restanti trocar in casi particolarmente complessi. In conclusione, la tecnica three port appare comparabile alla tradizionale laparoscopica, fornendo i vantaggi della riduzione del numero di accessi e delle complicanze a questi correlate.
