Gender Bias in the Integrated Plastic Surgery Residency: A Snapshot of Current Trends.

According to the American Society of Plastic Surgeons, the male to female ratio of plastic surgeons is approximately 5:1. As more surgical specialties are recruiting female residents, there has been an increase in the amount of females. We set out to examine the current trends in residency recruitment and whether a quantifiable gender bias exists. METHODS: A review of all the integrated plastic surgery programs within the United States was conducted. Data were collected regarding department or division status, the gender of the chairman and the program directors, the number of residents per year and gender of residents per year. The ratio of male to female residents was calculated. RESULTS: A total of 62 residency programs were identified. The vast majority had a male program director with only 8 female program directors identified. The mean ratio of female/male (F/M) residents overall was 1/1.2. Female program directors selected residents in the same ratio as their male counterparts [F/M ratio: 1/1.26 versus 1/1.18, p:0.813]. A linear logistic regression failed to identify the geographic location, department status, gender of the department chairman or the number of residents selected per year as predictors of higher F/M ratio. CONCLUSIONS: There are still fewer female program directors and residents in plastic surgery overall. However, neither was more likely to select a resident of their own gender. This analysis does not rule out the possible self-selection factor.

Validating clinical threshold values for a dashboard view of the compensatory reserve measurement for hemorrhage detection.

BACKGROUND: Compensatory reserve measurement (CRM) is a novel noninvasive monitoring technology designed to assess physiologic reserve using feature interrogation of arterial pulse waveforms. This study was conducted to validate clinically relevant CRM values with a simplified color-coded dashboard view. METHODS: We performed a prospective observational study of 300 injured patients admitted to a level I trauma center. Compensatory reserve measurement was recorded upon emergency department admission. Data collected to complement the analysis included patient demographics, vital signs, lifesaving interventions, Injury Severity Score (ISS), and outcomes. Threshold values of CRM were analyzed for predictive capability of hemorrhage. RESULTS: A total of 285 patients met the inclusion criteria. Mean age of the population was 47 years, and 67% were male. Hemorrhage was present in 32 (11%), and lifesaving intervention was performed in 40 (14%) patients. Transfusion of packed red blood cells was administered in 33 (11.6%) patients, and 21 (7.4%) were taken to the operating room for surgical or endovascular control of hemorrhage. Statistical analyses were performed to identify optimal threshold values for three zones of CRM to predict hemorrhage. Optimal levels for red, yellow, and green areas of the dashboard view were stratified as follows: red if CRM was less than 30%, yellow if CRM was 30% to 59%, and green if CRM was 60% or greater. Odds of hemorrhage increased by 12-fold (odds ratio, 12.2; 95% confidence interval, 3.8-38.9) with CRM less than 30% (red) and 6.5-fold (odds ratio, 6.5; 95% confidence interval, 2.7-15.9) with CRM of equal to 30% to 59% (yellow) when compared with patients with CRM of 60% or greater. The area under the receiver operating characteristic curve for three-zone CRM was similar to that of continuous CRM (0.77 vs. 0.79) but further increased the ability to predict hemorrhage after adjusting for ISS (area under the receiver operating characteristic curve, 0.87). CONCLUSION: A three-zone CRM could be a potentially useful predictor of hemorrhage in trauma patients with added capabilities of continuous monitoring and a real-time ISS assessment. These data substantiate easily interpretable threshold dashboard values for triage with potential to improve injury outcomes. LEVEL OF EVIDENCE: Diagnostic, level II.

Outcomes of Laparoscopic versus Open Fascial Component Separation for Complex Ventral Hernia Repair.

Ventral hernia recurrence rates have improved with advancements in technique. Open and laparoscopic fascial component separation techniques improve recurrence rates by allowing a tension free closure. This study examines laparoscopic component separation (LCS) and open component separation (OCS) techniques in the repair of complex ventral hernias and compares factors affecting patient outcomes. A retrospective chart review of patients who underwent ventral hernia repair with LCS and OCS was conducted between 2009 and 2013. Patient characteristics and outcomes were documented. Hernia recurrence was determined using physical exam and computed tomography if physical exam was equivocal. Univariate and multivariate analyses were performed. Ten patients underwent LCS and 38 underwent OCS. The rate of wound infection in the LCS group was 20 per cent versus 50 per cent in the OCS group. The overall rate of recurrence after LCS was 20 per cent, and 26 per cent in the OCS group. For body mass index > 30, the recurrence rate was 20 per cent in the LCS group and 29 per cent (P = 0.5) in the open group. The use of LCS demonstrates a trend in the reduction of hernia recurrence and wound infection overall and in patients with body mass index > 30 compared with OCS.

Combination chemotherapy regimen in a patient with metastatic malignant pheochromocytoma and neurofibromatosis type 1.

PATIENT: Female, 55 FINAL DIAGNOSIS: Metastatic malignant pheochromocytoma Symptoms: Chest pain • tachycardia • tachypnea MEDICATION: - Clinical Procedure: - Specialty: Oncology. OBJECTIVE: Rare disease. BACKGROUND: Malignant pheochromocytoma is defined as the occurrence of the tumor in an area that is normally devoid of chromaffin tissue, direct tumor invasion, and/or metastasis. Metastatic malignant pheochromocytoma is very rare. Malignant pheochromocytoma carries a poor prognosis with a 5-year survival rate of 44%. The majority of pheochromocytoma cases are sporadic, but a small portion (10%) can be associated with hereditary syndromes such as neurofibromatosis type 1 (NF1). CASE REPORT: A 55-year-old Hispanic woman presented to our care with chest pain. Her past medical problems included hypertension, neurofibromatosis type 1 (NF1), and pheochromocytoma status after right laparoscopic adrenalectomy, which was converted to open procedure about 19 months ago. Initial vital signs were significant for tachycardia, tachypnea, and hypertension. Computed tomography (CT) angiography of the chest was performed to rule out a pulmonary embolism, but instead revealed multiple bilateral lung nodules measuring up to 8 mm, consistent with metastasis. CT of the abdomen and pelvis revealed a lytic lesion in the posterior aspect of the left pedicle and transverse process of L4, and the neck/greater trochanter of the left femur. MIBG scan revealed widespread metastatic disease. She received an outpatient chemotherapy regimen of cyclophosphamide, dacarbazine, and vincristine. CONCLUSIONS: Metaiodobenzylguanidine (MIBG) is an alkyl-guanidine derivative similar to noradrenaline, which accumulates in tissue derived from neural crest cells. Current medical literature suggests that therapeutic 131I MIBG has a response rate of 50-75%. Combination chemotherapy using cyclophosphamide, vincristine, and dacarbazine has been the most widely used regimen for malignant pheochromocytoma. This combination of chemotherapy has been shown to have a high response rate and symptomatic improvement. Numerous therapeutic regimens exist for metastatic malignant pheochromocytoma; however, no regimen has been shown to have a benefit significantly superior to the others.
