Well-differentiated thyroid carcinoma (WDTC) represents a group of thyroid cancers with excellent prognosis. Age, a well-recognized risk factor for WDTC, has been consistently included in various prognostic scoring systems. An age threshold of 45 years is currently used by the American Joint Cancer Committee-TNM staging system for the risk stratification of patients. This study analyzes the relationship between the patients' age at diagnosis and thyroid cancer-specific survival in a population-based thyroid cancer cohort of 2115 consecutive patients with WDTC, diagnosed during 1970-2010, and evaluates the appropriateness of the currently used age threshold. Oncological outcomes of patients in terms of disease-specific survival (DSS) and disease-free survival (DFS) were calculated by the Kaplan-Meier method, while multivariable analysis was done by the Cox proportional hazard model and proportional hazards regression for sub-distribution of competing risks to assess the independent influence of various prognostic factors. The mean age of the patients was 47.3 years, 76.6% were female and 83.3% had papillary carcinoma. The median follow-up of the cohort was 122.4 months. The DSS and DFS were 95.4 and 92.8% at 10 years and 90.1 and 87.6% at 20 years, respectively. Multivariable analyses confirmed patient's age to be an independent risk factor adversely affecting the DSS but not the DFS. Distant metastasis, incomplete surgical resection, T3/T4 stages, Hurthle cell histology, and male gender were other independent prognostic determinants. The DSS was not independently influenced by age until the age of 55 years. An age threshold of 55 years is better than that of 45 years for risk stratification.

PURPOSE: Surgical resection of midface neoplasms and subsequent reconstruction have been shown to have significant negative effects on quality of life (QOL). The purpose of this pilot study was to assess individuals' health-related QOL after maxillectomy and reconstruction with a prosthetic obturator. MATERIALS AND METHODS: The QOL of 25 of 43 patients who underwent maxillectomy and prosthetic obturator reconstruction at the University of California-San Francisco was assessed using 3 questionnaires: University of Washington Quality of Life version 4 (UWQOL), Obturator Functioning Scale (OFS), and Mental Health Inventory (MHI). RESULTS: The response rate to the QOL questionnaires was 92% (23 of 25 patients). Time elapsed from maxillectomy and prosthetic obturator reconstruction to the QOL survey response ranged from 0.3 to 6.6 years (mean, 2.7 years; standard deviation [SD], 1.9 years). The post-treatment mean QOL scores were 77.3 (SD, 13.6) for UWQOL, 72.0 (SD, 12.6) for OFS, and 4.5 (SD, 0.9) for Mental Health Inventory. Individuals who received adjuvant radiation scored lower for speech and appearance (OFS, P = .05, P = .03, respectively) as well as for saliva and overall QOL (UWQOL, P = .02, P = .08, respectively). There was a strong correlation between QOL scores in OFS and UWQOL questionnaires (r = 0.78, P < .001). CONCLUSION: The results of this pilot study suggest that postoperative radiation therapy was the strongest variable affecting QOL in patients with maxillectomy and prosthetic obturator reconstruction. There is further need for a multicenter trial with a larger sample to identify how factors affecting QOL of patients after maxillectomy might influence the choice of reconstruction.

Many burn patients experience more intense pain from the split thickness skin donor site than in the grafted burn wound in their postoperative period. Often, split thickness autografts are harvested from the lateral thigh area, which is innervated by the lateral femoral cutaneous nerve (LFCN). Sonographic nerve localization has been an increasingly popular technique to provide regional nerve blocks and we explore its role in improving pain control during skin harvesting. The LFCN was identified and blocked using ultrasound in 16 patients with a variety of wounds. The donor site was tested and marked after the injection. General anesthesia or sedation was administered after markings were completed. A postoperative survey was performed to assess the return of sensation at the donor site. All blocks were successful with adequate visualization of LFCN using ultrasound. Full anesthesia at the donor site, defined as absence of pain in response to a sharp object prick, was tested at 15 min and confirmed at 20 min after the block. The size of the anesthetized field ranged from 119 to 630 cm(2), with a mean surface area of 268.5 cm(2). Donor site sensation returned within 5-16 h with a mean time of 9.1h. Ultrasound guided LFCN block provides a simple and safe choice of anesthesia for harvesting skin from the lateral thigh.

INTRODUCTION: Many surgeons fear that closed-suction drains serve as a portal for bacterial entry into surgical spaces. Despite a lack of supporting evidence, postoperative antibiotics are often prolonged while drains remain in place. METHODS: Medical records of all patients who underwent intraoperative Jackson-Pratt drain placement and sterile removal over a 12-month period were prospectively analyzed. RESULTS: Fifty-four patients with 101 drains were included. Drains were in place for 5 to 43 days [mean (SD), 13.5 (6.3) days]. Sixty-three percent of drains had positive cultures. All patients received perioperative antibiotics. Thirty-nine patients received postoperative antibiotics [mean (SD), 13.8 (13.8) days]. There were 2 cases of cellulitis. One patient required reoperation. CONCLUSIONS: Sixty-six drains (65.3%) were placed in the presence of prosthetic material. Although nearly two thirds of drains were colonized with bacteria, our wound infection rate was extremely low (5.6%). Thus, closed-suction drains may be left in place for an extended period without increasing the risk of infection, even in the presence of prosthetic material.

Congenital lower lip pits are cardinal findings of van der Woude syndrome [OMIM 119300]. The nosologic context of how lower lip pits are catalogued is easily lost because of insufficient clinical history, subtle findings misidentified as artifacts, lack of awareness by the pathologist, the perception that these are identify/confirm descriptive-diagnosis only, not necessarily an element of an actionable report, and/or the rarity with which these specimens are accessioned (in the authors' experience, less than 1 case per year). We present the salient findings on 19 lower lip pits specimens from the files of a single institution collected over the last 25 years.
