Fridman, Mikhail; Lam, Alfred King-Yin; Krasko, Olga; Schmid, Kurt Werner; Branovan, Daniel Igor; Demidchik, Yuri
OBJECTIVE: The aims were to analyse the features of papillary thyroid carcinoma in a large cohort of children and adolescents in Belarus and to study the influence of radiation exposure as well as the source of irradiation on the morphological and clinical presentations of tumours. DESIGN AND PATIENTS: The clinical and pathological features of 1086 young patients (age range=4 to 18 inclusive, followed up for >/=18years) with papillary thyroid carcinoma diagnosed during the years 1990 to 2010 were reviewed. The patients were divided into three groups: "external radiation-related", "post-Chernobyl" (internal irradiation-related) and "sporadic". Besides, patients from "post-Chernobyl" cohort (n=936) were further divided into the three equal subgroups according to the dates of surgery, which were corresponding to the early (4-9years), intermediate (10-12years) and long (14-18years) latency periods. RESULTS: Patients in the "external radiation-related" group often showed extra-thyroidal extension in tumours sized =10mm (p=0.002). Distant metastases were more frequently (p=0.006) discovered in patients with papillary thyroid carcinoma in post-Chernobyl group (104 of 936, 11.1%) when compared to juveniles from other two groups. Lateral nodal disease and distant metastases were often noted in post-Chernobyl patients operated during the early and intermediate latency periods only. CONCLUSION: Young patients in Belarus with papillary thyroid carcinoma in the "post-Chernobyl" group differed in many clinical and pathological parameters from those in the "sporadic" group. "External radiation related" papillary thyroid carcinomas were distinguished from other two groups of carcinoma in more advanced local spread and more aggressive behaviour of micro-carcinomas.

Comparative Study of Early Secondary Nasal Revisions and Costs in Patients With Clefts Treated With and Without Nasoalveolar Molding
Patel, Parit A; Rubin, Marcie S; Clouston, Sean; Lalezaradeh, Frank; Brecht, Lawrence E; Cutting, Court B; Shetye, Pradip R; Warren, Stephen M; Grayson, Barry H
The present study aims to determine the risk of early secondary nasal revisions in patients with complete unilateral and bilateral cleft lip and palate (U/BCLP) treated with and without nasoalveolar molding (NAM) and examine the associated costs of care. A retrospective cohort study from 1990 to 1999 was performed comparing the risk of early secondary nasal revision surgery in patients with a CLP treated with NAM and surgery (cleft lip repair and primary surgical nasal reconstruction) versus surgery alone in a private practice and tertiary level clinic. The NAM treatment group consisted of 172 patients with UCLP and 71 patients with BCLP, whereas the non-NAM-prepared group consisted of 28 patients with UCLP and 5 with BCLP. The risk of secondary nasal revision for patients with UCLP was 3% in the NAM group and 21% in the non-NAM group. The risk of secondary nasal revision for patients with BCLP was 7% in the NAM group compared with 40% in the non-NAM group. Using multicenter averages, the non-NAM revision rates were calculated at 37.8% and 48.5% for U/BCLP, respectively. Applying these risks of revision, NAM treatment led to an estimated savings of between $491 and $4893 depending on the type of cleft. In conclusion, NAM can reduce the number of early secondary nasal revision surgeries and, therefore, reduce the overall cost of care.

Nonschwannoma Tumors of the Cerebellopontine Angle
Friedmann, David R; Grobelny, Bartosz; Golfinos, John G; Roland, J Thomas Jr
Although the preponderance of cerebellopontine angle lesions are schwannomas, focused attention to patient clinical history, imaging studies, and tissue biopsies when indicated will aid in detection of less common lesions that might otherwise be misdiagnosed. This is most critical for pathologies that dictate different management paradigms be undertaken.

Parathyroid Localization and Preservation during Transcervical Resection of Substernal Thyroid Glands
Heineman, Thomas E; Kadkade, Prajoy; Kutler, David I; Cohen, Marc A; Kuhel, William I
OBJECTIVE: The feasibility of parathyroid preservation during thyroidectomy has not been well documented for cases in which the thyroid gland extends into the mediastinum. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic referral center. SUBJECTS AND METHODS: In this retrospective cohort study, 70 consecutive patients who had substernal thyroid glands treated with a transcervical thyroidectomy between 1993 and 2013 were compared with 286 thyroidectomies that did not entail substernal extension within that same time period. All localized parathyroid glands were confirmed histologically. RESULTS: Of 160 possible parathyroid glands in the substernal cases, 119 (74%) were histologically confirmed intraoperatively (67 superior and 52 inferior). In nonsubsternal cases, 725 (89%) were histologically confirmed (372 superior and 353 inferior). There was a statistically significant difference between the substernal and nonsubsternal cases in the total number of glands found (P < .0001) and the number of superior and inferior glands that were identified (P = .009 and < 0.0001). CONCLUSIONS: Even when the thyroid gland extends into the mediastinum, it is often possible, although with reduced efficiency, to identify and preserve the parathyroid glands.

The effect of endoscopic olfactory cleft polyp removal on olfaction
Kuperan, Arjuna B; Lieberman, Seth M; Jourdy, Deya N; Al-Bar, Mohammad H; Goldstein, Bradley J; Casiano, Roy R
BACKGROUND: The presence of olfactory cleft polyps in chronic rhinosinusitis with nasal polyposis is well documented, but the effect of endoscopic olfactory cleft polyp surgery on olfaction, versus observation, has not been well studied. This analysis assessed if microdebridement of olfactory cleft polyps yields significant objective smell improvements in those with anosmia or hyposmia. METHODS: A randomized prospective single-blinded study was performed on patients undergoing bilateral endoscopic sinus surgery with profound bilateral nasal polyposis, excluding those younger than 18 years or without olfactory polyps. A preoperative University of Pennsylvania Smell Identification Test (UPSIT), visual analog scale (VAS), and sinonasal outcomes 20 score (SNOT-20), and a follow-up at 6 months was performed. Two cohorts were created, including one with cleft polyp removal (group A) and one with cleft polyps left in place (group B). RESULTS: There were 10 patients in group A and 7 in group B. By using the Wilcoxon signed rank test, the two groups were individually analyzed for changes in the preoperative UPSIT, VAS, and SNOT-20 versus the 6-month test results. In group A, the improvement in the UPSIT, VAS, and SNOT-20 were statistically significant at p < 0.05. For group B only the improvement in the VAS was statistically significant, at p < 0.05. There was a statistically significant difference in clinical smell improvement between group A and B at 6 months (p = 0.00512). CONCLUSIONS: Evidence exists that olfactory cleft polyp surgery improves olfactory function outcomes. Long-term data beyond 6 months is needed to further validate these early promising outcomes.

The impact of compliance in posttreatment surveillance in head and neck squamous cell carcinoma
Deutschmann, Michael W; Sykes, Kevin J; Harbison, John; Cabrera-Muffly, Cristina; Shnayder, Yelizaveta
IMPORTANCE: Posttreatment surveillance (PTS) is a key component in the treatment of patients with head and neck cancer. It is unclear how beneficial this is in improving patients' survival. OBJECTIVE: To determine how compliance with follow-up affects clinical outcomes in patients with head and neck squamous cell carcinoma. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective cohort study at a tertiary academic center of a total of 332 patients with head and neck squamous cell carcinoma who had completed both treatment and follow-up at the University of Kansas Medical Center. Patient and tumor characteristics, socioeconomic status, and geographic data were collected. EXPOSURES: Compliance with PTS. MAIN OUTCOMES AND MEASURES: The effect of compliance with PTS on overall survival. RESULTS: Compliance with PTS, US Census tract income level, and the distance patients travel for follow-up had significant effects on survival (P = .001, P = .001, and P = .01, respectively). Cox proportional hazard models revealed that more advanced disease (hazard ratio [HR], 1.76 [95% CI, 1.21-2.58]; P = .003), middle (HR, 1.64 [95% CI, 1.13-2.39]; P = .009) and moderate (HR, 1.90 [95% CI, 1.18-3.06]; P = .008) census tract income level, and age (HR, 1.03 [95% CI, 1.01-1.04]; P < .001), were significantly associated with an increased risk of death. There was an association between compliance and tobacco cessation (P = .003), as well as the distance a patient lived from the medical center (P = .008). CONCLUSIONS AND RELEVANCE: Patients with head and neck squamous cell carcinoma were significantly more likely to survive with completion of follow-up and tobacco cessation. Compliance with PTS was associated with smoking cessation and traveling less than 200 miles for follow-up.

Anaplastic large-cell lymphoma presenting as a nasopharyngeal mass and cervical lymphadenopathy [Case Report]
Dion, Gregory R; Packer, Mark D
Cervical lymphadenopathy in adults has a broad differential diagnosis, including bacterial and viral infections, Kikuchi-Fujimoto disease, systemic lupus erythematosus, and various neoplasms. Many of its etiologies share similar symptomatology and presentations, which complicates the diagnosis. A thorough history and a comprehensive physical examination, to include nasopharyngoscopy and imaging as indicated by the specific case, are key to determining the origin of the lymphadenopathy and to avoid a missed or delayed diagnosis. Based on our review of the literature, we present the second reported case of anaplastic lymphoma kinase-positive anaplastic large-cell lymphoma presenting in an adult with an obstructing adenoid/nasopharyngeal mass and lymphadenopathy. The mass, which occurred in a 19-year-old woman of Asian descent, caused nasal airway obstruction in the setting of cervical lymphadenopathy that was initially ascribed to mononucleosis.
