Lymph Node Metastases from Non-Melanoma Skin Cancer of the Head and Neck.

Non-melanoma skin cancer (NMSC) represents the most common malignancy in the world, comprising exceedingly common lesions such as basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) and rare lesions such as Merkel cell carcinoma. Risk factors are widely recognized and include ultraviolet (UV) light exposure, radiation exposure, immunosuppression, and many others. As a whole, survival and functional outcomes are favorable, but each histopathological subtype of NMSC behaves differently. Treatment regimens for the primary site usually include wide surgical excision and neck dissection in cases of clinically involved metastatic lymph nodes. The elective management of draining nodal basins, however, is a contested topic. Nearly all subtypes, excluding BCC, have a significant risk of lymphatic metastases, and have been studied with regard to sentinel lymph node biopsy (SLNB) and elective neck dissection. To date, no studies have definitively established a true single standard of care, as exists for melanoma, for any of the NMSCs. As a result, the authors have sought to summarize the current literature and identify indications and management options for the management of the cervical lymphatics for each major subtype of NMSC. Further research remains critically necessary in order to develop complete treatment algorithms.

Utility of Second-Look Endoscopy with Debridement After Pediatric Functional Endoscopic Sinus Surgery in Patients with Cystic Fibrosis.

OBJECTIVES: To determine the utility of Second-look endoscopy with debridement (SLED) after functional endoscopic sinus surgery (ESS) in pediatric cystic fibrosis (CF) patients. To compare outcomes in pediatric CF patients undergoing sinus surgery for chronic sinusitis with or without SLED. To describe findings present at the time of SLED. METHODS: Retrospective chart review of 61 ESS procedures performed at a tertiary care pediatric center from 2013 to 2016. Data collected included demographics, SLED findings, and 6-month pre-/postoperative disease specific outcomes including incidence of sinonasal and pulmonary exacerbations and revisions. RESULTS: Sixty-one cases were reviewed. SLED was performed in 38 cases on average 22.4 days postoperatively. Average preoperative Lund-Mackay score was 14.9 and 14.8 among patients undergoing ESS with and without SLED, respectively. Pre-/postoperative intranasal steroid use and extent of surgery performed was similar among all patients. At the time of SLED, rates of synechiae, polyps and maxillary antrostomy obstruction were 26.3%, 23.7%, and 7.9%, respectively. The incidence and number of days to onset of postoperative sinonasal exacerbations requiring antibiotic therapy within 6 months of ESS were 1.0 (SD 1.0) and 85 days (SD 45.7); and 1.3 (SD 1.0) and 80.4 days (SD 40.5) for patients undergoing ESS with and without SLED, respectively (P value .33). The number of days to first pulmonary exacerbation was 113.9 (SD 45.5) and 47.4 (SD 34.1) among SLED and non-SLED patients, respectively (P value .01). No significant difference was observed in revision rates and time to revision ESS (30% and overall average 1.4 years, respectively). CONCLUSION: The utility of SLED among pediatric CF patients remains unclear. While debridement did not have a significant impact on sinonasal exacerbations or revision rates, pulmonary exacerbations for patients undergoing SLED were delayed. Further studies are needed to clarify the impact of SLED.

Student Leadership Development Initiative: A Pilot for a Sustainable, Replicable Model for Incorporating Leadership into Medical Education.

INTRODUCTION: Today's medical students are tomorrow's leaders. As leadership training becomes incorporated into undergraduate medical education, there is a need for validated educational models that are both effective and replicable. METHODS: Between April 2017 and October 2017, groups of 15 to 20 medical students participated in sessions with an exemplary physician leader incorporating a guided interview format and discussion about her or his career. Prepared questions ensured leadership domains were covered. The program was evaluated using a post-session survey. RESULTS: One hundred percent of survey respondents (N = 58) reported that the session was a good use of time. Seventy-eight percent felt more prepared to lead a team; 93% learned specific ways to improve their leadership skills. DISCUSSION: This leadership program is a unique model to provide leadership education to medical students that is both effective and replicable.

Predictors of Postoperative Urinary Tract Infection After Bariatric Surgery.

BACKGROUND: In bariatric surgery patients, urinary tract infections (UTIs) are one of the most common postoperative infections. In this study, we sought to determine if preoperative patient factors and perioperative processes contribute to an increased risk of UTI. METHODS: A retrospective analysis was performed of patients who underwent bariatric surgery at a single institution between March 2012 and May 2016. Standard protocol was antibiotic prophylaxis with cefazolin. Patients with a penicillin allergy received clindamycin. Urinary catheters were placed selectively. A univariate and multivariate analyses were performed to determine risk factors for patients who developed a UTI within 30 days postoperatively. RESULTS: Six hundred ninety-four patients (82.7% female) underwent bariatric surgery in the study interval. UTIs were more common in females (4.9 vs. 1.7%, p = 0.12). On univariate analysis age, operative time, length of stay, urinary catheter placement, clindamycin prophylaxis, and revisional surgery were significantly correlated with UTI. A multivariate logistic regression model revealed the risk of UTI increased 5.38-fold [95% confidence interval (CI) 2.41-12.05] with clindamycin use, 6.37-fold [95% CI 2.22-18.18] with revision surgery, and 1.25-fold [95% CI 1.05-1.49] for every 5 years gained in age. CONCLUSIONS: Older age, clindamycin prophylaxis, and revisional procedures are significantly associated with an increased rate of UTI following bariatric surgery. Several identified variables are modifiable risk factors and targets for a quality improvement initiative to decrease the rate of UTI in bariatric surgery patients.

Perioperative bleeding and blood transfusion are major risk factors for venous thromboembolism following bariatric surgery.

BACKGROUND: Morbidly obese patients are at increased risk for venous thromboembolism (VTE) after bariatric surgery. Perioperative chemoprophylaxis is used routinely with bariatric surgery to decrease the risk of VTE. When bleeding occurs, routine chemoprophylaxis is often withheld due to concerns about inciting another bleeding event. We sought to evaluate the relationship between perioperative bleeding and postoperative VTE in bariatric surgery. METHODS: The American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) dataset between 2012 and 2014 was queried to identify patients who underwent bariatric surgery. Gastric bypass (n = 28,145), sleeve gastrectomy (n = 30,080), bariatric revision (n = 324), and biliopancreatic diversion procedures (n = 492) were included. Univariate and multivariate regressions were used to determine perioperative factors predictive of postoperative VTE within 30 days in patients who experience a bleeding complication necessitating transfusion. RESULTS: The rate of bleeding necessitating transfusion was 1.3%. Bleeding was significantly more likely to occur in gastric bypass compared to sleeve gastrectomy (1.6 vs. 1.0%) (p < 0.0001). For all surgeries, increased age, length of stay, operative time, and comorbidities including hypertension, dyspnea with moderate exertion, partially dependent functional status, bleeding disorder, transfusion prior to surgery, ASA class III/IV, and metabolic syndrome increased the perioperative bleeding risk (p < 0.05). Multivariate analysis revealed that the rate of VTE was significantly higher after blood transfusion [Odds Ratio (OR) = 4.7; 95% CI 2.9-7.9; p < 0.0001). Predictive risk factors for VTE after transfusion included previous bleeding disorder, ASA class III or IV, and COPD (p < 0.05). CONCLUSIONS: Bariatric surgery patients who receive postoperative blood transfusion are at a significantly increased risk for VTE. The etiology of VTE in those who are transfused is likely multifactorial and possibly related to withholding chemoprophylaxis and the potential of a hypercoagulable state induced by the transfusion. In those who bleed, consideration should be given to reinitiating chemoprophylaxis when safe, extending treatment after discharge, and screening ultrasound.
