OBJECTIVE:Surgical residents often begin the internship without prerequisite skills necessary for appropriate patient care. The purpose of this study was to develop a surgical internship readiness elective or senior medical student (SMS) "Boot Camp" for fourth-year medical students to prepare them for the rigors of surgery internship. DESIGN:Sixteen fourth-year medical students completed a series of clinical and didactic sessions over a 4-week elective. Students evaluated the effectiveness of the elective with a pre- and post-survey that focused on confidence levels in 4 areas: anatomic dissection, administrative skills, technical skills, and patient management. Students also participated in a focus group session that identified strengths and weaknesses of the elective. Students were also assessed on performance by anesthesiology faculty in the mock patient code and by nursing faculty in mock nursing page sessions. RESULTS:Upon completion of the elective, students rated themselves as more confident in all 57 categories on the survey. During the focus group session, students identified several strengths of the elective and offered recommendations for improvements in the elective. CONCLUSION:The SMS "Boot Camp" gave fourth-year medical students confidence and an opportunity to develop necessary prerequisite skills to begin the surgery internship.
OBJECTIVE:Prior data have shown that resident duty-hour reform has not affected faculty work hours; yet the preservation of faculty hours may have been at the expense of productivity. We sought to examine change in clinical productivity.DESIGN:Anonymous survey and analysis of faculty relative value units (RVU) database.SETTING:A single, large academic medical center.PARTICIPANTS:All clinical faculty in the Department of Surgery.METHODS:An anonymous survey was distributed to surgical faculty 18 months after reform and compared with surveys taken before and after reform. Opinions regarding productivity and working hours were solicited. P values were determined by chi-square or Student t-tests. Relative value unit data, reflecting clinical productivity, were compared before and after reform. Regression was performed with dependent variable "lnRVU" and independent variables "calendar month," "pre/post" July 2003, and "surgeon." The coefficient on "pre/post" reflected average change in RVUs.RESULTS:A total of 49 of 73 surveys were returned (67% response). Faculty reported an average of 68.0+/-7.0 weekly work hours (p=NS compared with previous survey). In the current survey, 35% felt their overall productivity had fallen due to reform. Among these, 83% felt academic productivity had suffered, 11% were unsure, and 1 person (6%) believed academic productivity was preserved. The majority (82%) reported preserved clinical productivity, 6% reported a decrease, and 12% were unsure. Overall, 60% reported doing work previously done by residents. When RVU data were examined, the coefficient on change pre- and post-reform indicated a 5.7% increase in productivity (p=0.005). However, this effect was driven by 5 surgeons with a greater than 75% increase in productivity, all young faculty, early in practice. Excluding these, there was no significant change (0.6% increase, p=0.77).CONCLUSIONS:Faculty have preserved work hours and clinical productivity, despite a tendency to take on work previously done by residents. This suggests that academic activities may have suffered.
BACKGROUND:In an attempt to prevent or alter the course of acute renal failure, many surgeons continue to use low-dose dopamine. This article critically reviews the physiologic reasons why low-dose dopamine is not clinically efficacious.METHODS:A critical review of English language literature.RESULTS:The effect of dopamine on renal blood flow remains controversial. If dopamine does increase renal blood flow, the vascular anatomy of the kidney would limit its effectiveness. Rather than improving renal function, dopamine has been shown to impair renal oxygen kinetics, inhibit feedback systems that protect the kidney from ischemia, and may worsen tubular injury. Dopamine has not been proven useful in the prevention or alteration of the course of acute renal failure as a result of heart failure, cardiac surgery, abdominal aortic surgery, sepsis, and transplantation. Dopamine has been associated with multiple complications involving the cardiovascular, pulmonary, gastrointestinal, endocrine, and immune systems.CONCLUSIONS:Based on the anatomy and physiology of the kidney, low-dose dopamine would not be expected to improve renal failure and this has been demonstrated by the lack of efficacy in clinical trials.
There are currently no clear guidelines for use of pan- or selective CT in elderly trauma patients and this subject matter remains controversial. The aim of this study is to compare the outcome of elderly trauma patients in a level 1 trauma centre who required a pan- or selective CT scan on admission.The Trauma Audit Research Network database was reviewed to identify eligible patients (≥65 years) over a one-year period, from January 2018 to January 2019. Patients’ demographics, mechanism of injury, injury severity score, length of hospital stay (LOS), mortality and type of CT scans done were recorded. The inclusion criteria were elderly patients ≥65 years involved in acute trauma setting (less than one day between incident and emergency department presentation and blunt mechanism of injury). Exclusion criteria were patients <65 years, perforating mechanism of injury and patients with delayed presentation more than one day after the incident, and patients who have not got any CT scan at presentation. Statistical analyses were undertaken on SPSS (version 25.0; IBM, New York, USA).In total, 481 patients with the mean age of 80.8 years were evaluated (48.6% male). Among them 232 cases were multiple injuries while 249 were single system injuries. And 235 patients (48.8%) underwent pan-CT in whom 66.8% were multiple injuries; 246 (51.1%) did selective CT scan in whom 69.5% were single system injuries. In multiple injury patients, performing a pan-CT scan on presentation was associated with shorter LOS compared to those who had a selective CT, in which 76.4% patients spent < 21 days in the pan-CT group compared to 16.0% for those investigated by selective CT scan (p < 0.001); and 2.5% spent > 60 days in pan-CT group compared to 64% in selective CT group (p < 0.0001). Performing pan-CT was also associated with lower need to repeat CT (p < 0.01). In patients with a single system injury, no differences were found in LOS or the need to repeat CT if either pan-CT or selective CT were requested.We recommend doing pan-CT scan in all elderly patients with multiple system injuries as it decreases the LOS and the need for another CT during hospital stay. No difference in LOS or the need to repeat another CT if pan-CT or selective CT were requested initially in single system injuries. Although age and injury severity score are poor predictors for the need to do pan-CT, the mechanism of injury may be helpful.
The purpose of this study is to review the patterns of cervical spine evaluation in blunt trauma patients to identify redundant, inefficient, or risky practices at our community hospital.
ittoral cell angioma (LCA) is a benign tumor of the spleen that as first described by Falk et al in 1991 when they illustrated 7 cases of “a novel type of vascular tumor.” In 1998, Bisceglia t al made the association of LCA with epithelial malignancies. ince then, a total of 74 cases have been reported, 25 (33%) of hich are associated with other malignancies, and 16 cases are ssociated with other issues of immune dysregulation. The first ase of LCA associated with transitional cell carcinoma (TCC) f the bladder is reported.
Bronchopulmonary sequestration is an uncommon developmental abnormality that frequently presents as an incidental mass. Differential diagnosis includes malignancy. Reports of extralobar abdominal pulmonary sequestration in adults are sparse. Only 2.5% of all pulmonary sequestrations are detected below the diaphragm. The authors present a case of a 45-year-old woman and a literature review. Computed tomography, magnetic resonance imaging, and operative and pathologic findings are provided. A review of diagnosis and therapy is presented.
Disorders of fatty tissue metabolism and body contour are frequently described in the literature. Several different syndromes have been ascribed to recurring characteristics of fatty deposition with similar underlying etiologies. These syndromes can generally be classified into the lipomatoses (abnormal accumulations of fat) and the lipodystrophies (abnormal fat atrophy). The authors describe a case of isolated symmetrical lipomatosis of the soft tissue overlying the trochanters that developed a recurrence after treatment with liposuction. They have attempted to match this patient's disorder into 1 of several reported syndromes, with benign symmetric lipomatosis and acquired partial lipodystrophy at the top of the differential diagnosis. However, some characteristics of this patient may warrant a separate categorization for her condition. In this case report, the current literature on disorders of fatty tissue metabolism is reviewed and a discussion of relevant factors and issues surrounding their clinical significance and management is provided.
BACKGROUND:Currently over 5000 patients are receiving hemodialysis in Australia, which is an increase by approximately 7% each year. Distal ischemia secondary to the steal syndrome (ISS) is an uncommon but recognized complication. Several methods are now available to manage this problem including ligation, banding, and distal revascularization with interval ligation (DRIL). The aim of this report is to review the experience of the authors on this complication and its management at Royal Perth Hospital.METHODS:The Vascular Physiology Laboratory Database was used to identify those patients referred for investigation of ISS. Data were collected retrospectively from these patients' files concerning their demographics, graft particulars, and type of interventional procedure. Patients were then recalled to assess long-term patency and current venous access and for postoperative vascular studies.RESULTS:Eighteen people were identified with ischemic symptoms. The mean age was 66 (range, 44 to 82). Fourteen (77.8%) were men, and 15 (83.3%) were diabetic. Renal failure was secondary to diabetes in 8 patients, hypertension in 3, and a combination of both in 7 patients. Intervention was via the DRIL procedure in 12, ligation in 5, and banding in 1. One patient underwent angioplasty of the ulnar artery before DRIL. At follow-up (between 1 and 12 months), all DRIL bypass were patents. The 5 ligated patients all improved, and the patient who underwent banding thrombosed their graft.CONCLUSION:The DRIL procedure should be considered the standard operation to manage ISS in that it manages the ischemia while maintaining the functional fistula. It is, however, still necessary to ligate some fistulae and seek alternative access. There are still no preoperative indicators as to who will suffer ISS.
urgical residency training is undergoing a forced metamorhosis in the 80-hour workweek era. Prior surgical residents ained knowledge, technical skill, and judgment through an immersion model,” working 100 to 120 hours per week in a uccessful but unstructured educational model. Newer trainng models like the “mentorship model,” “case-based model,” nd “night float model” offer new ideas aimed at improving fficacy of surgical residency training to accommodate the 80our workweek. In developing new models, care must be aken not to optimize resident training at the expense of patient are. Continuity of care has been recognized by the Surgery esidency Review Committee (SRRC) as an “essential” part of urgical residency training. The literature lends support to he idea of continuity of care improving patient care through ecreased complications in hospitalized patients. The SRRC has taken the poorly defined term continuity of are and defined 6 elements in which the same surgery resident ust be involved: (1) Determine or confirm a diagnosis, (2) rovide preoperative care, (3) discuss the case with the attendng physician, (4) select and accomplish the appropriate proceure, (5) direct postoperative care, and (6) follow up after disharge. Compliance with continuity of care is important at ll levels of training, especially for senior-level residents. To ur knowledge Anderson and Sidhu are the only other 2 roups closely analyzing compliance rates of surgical residents ith each of the 6 elements of patient care defined by the RRC. The goals of surgical training should strive for “perfect ontinuity,” in which the same resident maintains involvement ith the same patient through all 6 elements of care. Anderon and Sidhu attained perfect continuity rates of 23.7% and 0%, respectively. Our objective is to provide updated data on
PURPOSE:We continue to increase the amount of evaluations to improve the outcomes of our residency programs. Although ongoing faculty evaluations clearly are an important part of faculty development, their value in terms of improving the program needs to be evaluated. The questions asked were as follows: (1) Do faculty evaluations continue to improve the faculty over the course of successive evaluation periods? (2) Are there groups of faculty who would benefit the most from faculty evaluation feedback? (3) Are there any specific objective categories within the evaluation that carry more value and may help to shorten this form?METHODS:Forty-two faculty members were evaluated by 40 surgical residents with an assessment form developed by surgical residents that assessed faculty members by 10 different criteria. The initial set of data was collected, and attending surgeons were given an intervention in the form of a letter detailing how they had been assessed in each of the 10 categories. The attending surgeons were evaluated again 6 months later and were given an intervention in the form of verbal feedback regarding their evaluations. The attending faculty members were then assessed 1 year after that. One way analyses of variance and Fisher Protected Least Significant Difference (PLSD) were used to analyze the resulting data to determine if there were significant differences in the faculty evaluations. A part-whole correlation was performed that correlated the 10 evaluation criteria against the mean score on each evaluation, and partial eta-squared analysis was used to determine which criterion had the largest effect on the overall means.RESULTS:The means for the 42 faculty members as a whole continued to improve from the first to the final evaluation period, with 30 faculty members increasing their mean score (18 significantly) and 12 decreasing their mean score (4 significantly). Seven of the 10 evaluation criteria's means improved sequentially by feedback session. These were (1) Didactic Teaching, (2) Teaching Rounds, (3) Attendance at Didactic Activities, (4) Allows [Resident] Autonomy to Make Independent Decisions, (5) Provides Feedback, (6) Stimulates Critical Thinking with Use of Literature, and (7) Encourages and Maintains an Atmosphere of Professional Mutual Respect for All Members of Health Care Team (Role Model). The faculty group with the lowest evaluations improved significantly more than those of both the middle and the role model group, with the middle and the role model groups improving, but not significantly differently from each other. Of the criteria that improved, only Provides Feedback improved significantly from the first to second and the second to third evaluation periods. The three criteria with the highest correlation coefficients were Role Model (0.76), Provides Feedback (0.75), and Stimulates Critical Thinking (0.74). The results from the partial eta-squared test showed that the criterion with the largest effect size was Provides Feedback (0.28). These analyses indicate that the criterion Provides Feedback was both highly correlated with the average score on a faculty member's evaluation and was more responsible than any other criteria for the overall improvement in the mean evaluation score of the faculty members.CONCLUSIONS:(1) Ongoing faculty evaluations indeed are a powerful tool to improve the faculty as a whole. (2) The faculty members with the lowest evaluations showed the largest amount of improvement. (3) Providing feedback to the residents seems to be the most valued factor by the residents for faculty evaluations and perhaps could become the basis of the evaluation for the most accomplished faculty.
OBJECTIVES:To assess the impact of a focused academic support program on American Board of Surgery In-Training Examination (ABSITE) scores and Qualifying Examination (QE) outcomes. METHODS:A mandatory intervention program was begun in April 2001 for residents with ABSITE Total Test (TT) percentiles <31. Program elements included: 1) individual faculty mentoring and personal learning plan 2) QE videotape review sessions 3) Surgical Education and Self-Assessment Program (SESAP) 4) monthly rotation evaluations, and 5) quarterly status feedback. A free medical evaluation was offered. Mock orals participation, educational psychologist consultation, and voluntary followup mentoring were added later. Study data were reviewed for 2003-2005 Chief Residents including ABSITE scores, QE results, conference attendance, rotation Overall Performance ratings, and resident surgeon case volumes. Results were compared for the academic intervention (AI) and no intervention (NI) groups. RESULTS:Fifteen residents graduated during the study period. Eight residents completed nine interventions; seven returned to TT percentiles >30 (7/8, 88%). First post-intervention ABSITE gains were large compared to NI and national peer groups. Standard Score (SS) TT gains were maintained until residency completion by four AI residents. Median AI PGY-5 TT percentile was 32 and three scores were
In many jurisdictions with Graduated Driver Licensing systems, such as those in North America, Australia, and New Zealand, parents play an important role in teaching their child how to drive and facilitating their access to formal driver education. This study explored parents’ views on these processes in a theoretically grounded manner using the Goals for Driver Education (GDE) Framework. The GDE framework groups influences on young driver behaviour into four interconnected hierarchical levels: vehicle manoeuvring (Level 1), mastery of traffic situations (Level 2), goals and contexts for driving (Level 3) and goals for life and skills for living (Level 4). Fourteen parents of novice drivers participated in five focus groups held in urban and regional locations in South East Queensland, Australia. A six-step thematic analysis was used consisting of (1) familiarisation with the data, (2) generation of initial codes, (3) searching for themes, (4) reviewing themes, (5) defining and naming themes and (6) producing the report. Parents indicated that they were more likely to outsource the teaching of skills at Levels 1 and 2 of the GDE to professional driving instructors as they were concerned that they would pass bad habits onto their child or they were unaware of the road rules that their child was required to follow. Parents believed that they were able to more effectively teach skills located on Levels 3 and 4 of the GDE framework because they had a greater knowledge of their child when compared with professional educators. The study findings can be used to develop an intervention that would support parents to more effectively supervise learner drivers.
In this study we characterized Amblyomma americanum (Aam) tick calreticulin (CRT) homolog in tick feeding physiology. In nature, different tick species can be found feeding on the same animal host. This suggests that different tick species found feeding on the same host can modulate the same host anti-tick defense pathways to successfully feed. From this perspective it's plausible that different tick species can utilize universally conserved proteins such as CRT to regulate and facilitate feeding. CRT is a multi-functional protein found in most taxa that is injected into the vertebrate host during tick feeding. Apart from it's current use as a biomarker for human tick bites, role(s) of this protein in tick feeding physiology have not been elucidated. Here we show that annotated functional CRT amino acid motifs are well conserved in tick CRT. However our data show that despite high amino acid identity levels to functionally characterized CRT homologs in other organisms, AamCRT is apparently functionally different. Pichia pastoris expressed recombinant (r) AamCRT bound C1q, the first component of the classical complement system, but it did not inhibit activation of this pathway. This contrast with reports of other parasite CRT that inhibited activation of the classical complement pathway through sequestration of C1q. Furthermore rAamCRT did not bind factor Xa in contrast to reports of parasite CRT binding factor Xa, an important protease in the blood clotting system. Consistent with this observation, rAamCRT did not affect plasma clotting or platelet aggregation. We discuss our findings in the context of tick feeding physiology.
The placement of hemodialysis catheters are widely performed by vascular surgeons and surgical residents for use in both the hospital and the outpatient setting. Although long-term complications of this type of vascular access are relatively uncommon, an appreciation is warranted for the life-threatening complication of right atrial thrombus (RAT). Once recognized, medical or surgical management is mandatory to prevent further consequences from RAT. The optimal treatment for catheter-induced RAT is still controversial. Our case and review illustrates how the routine placement of a malpositioned hemodialysis catheter in a young man can lead to the serious complication of RAT that necessitated cardiac surgery after thrombolysis failed. We describe the successful surgical management of a hemodialysis catheter-induced RAT and suggest that in cases of large, mobile RATs with adherence to both atrial wall and catheter, suspicion or evidence of pulmonary embolus (PE), and low-risk surgical candidates, open thrombectomy may be an optimal and definitive treatment.
Perforated Meckel's diverticulum (MD) is a rare complication of pregnancy. Its diagnosis, however, must be considered in all cases of intra-abdominal disease, as its presentation is similar to appendicitis. Prompt diagnosis and appropriate treatment is imperative in these cases due to the high rate of perforation leading to fetal and maternal morbidity and mortality. The usual lesion affecting a patient with MD and a review of the literature on other unusual causes of an acute abdomen in pregnancy is presented in the following report.
