Laryngeal Contact Ulcer.

A 47-year-old man presented to the otolaryngology service with complaint of 6 months of intermittent globus sensation. He reported constant throat clearing and subjective lowering of his voice. Flexible nasolaryngoscopy revealed a large pedunculated mass originating from the left vocal process of the arytenoid, lying superior to the vocal fold.

Sinonasal Ameloblastoma.

Ameloblastomas are benign but aggressive odontogenic tumors that most commonly affect the posterior mandible. Approximately 15% occur in the maxilla, with a subset thought to originate from the epithelial lining of the sinonasal cavities. Histologically, sinonasal ameloblastomas are identical to those of the oral cavity, with classical features of palisaded columnar basilar cells surrounding a central proliferation that resembles the stellate reticulum of a developing tooth.

Surgical management of arrested hydrocephalus: Case report, literature review, and 18-month follow-up.

Objective: Arrested hydrocephalus is stable ventriculomegaly without evidence of neurologic deterioration or symptoms. Management of arrested hydrocephalus in asymptomatic adults is controversial, with little clinical data. This case highlights the potential for decompensation in adults with arrested hydrocephalus and reviews the literature regarding pathophysiology and management of this clinical entity.

Antibiotic Impregnated External Ventricular Drains: Meta and Cost Analysis.

Objective: To determine whether antibiotic impregnated external ventricular drains (AI-EVDs) are effective in preventing ventriculostomy associated infection (VAI), and to examine their cost effectiveness.

Methods: A comprehensive literature search was performed for published data through May 2014, including randomized controlled trials and observational cohort studies comparing AI-EVDs with nonimpregnated controls. A meta-analysis of included studies was performed using a random effects model.
