The Size of Internal Auditory Canal Diverticula Is Unrelated to Degree of Hearing Loss.

Objectives: To explore the relationship between hearing loss and the internal auditory canal (IAC) diverticula. To determine whether diverticula exist within or medial to the otic capsule and the prevalence in a control population.

Methods: Retrospective review of adult patients with radiologic evidence of an IAC diverticulum, no evidence of otosclerosis, and audiometric testing.

Implementing Contrast Reaction Management Training for Residents Through High-Fidelity Simulation.

Rationale And Objectives: Adverse reactions to intravenous contrast for radiologic examinations can result in significant patient morbidity and mortality. It is critical that radiologists be proficient at recognizing and treating reactions in a timely and appropriate manner. Therefore, we developed a hands-on simulation curriculum to improve residents' ability and comfort in recognizing and responding to contrast reactions.

Prevalence of Internal Auditory Canal Diverticulum and Its Association with Hearing Loss and Otosclerosis.

Background And Purpose: Focal low-attenuation outpouching or diverticulum at the anterolateral internal auditory canal is an uncommon finding on CT of the temporal bone. This finding has been described as cavitary otosclerosis in small case reports and histology series. The purpose of this study was to establish the prevalence of internal auditory canal diverticulum and its association with classic imaging findings of otosclerosis and/or hearing loss.

Ecology of Bats, Their Ectoparasites, and Associated Pathogens on Saint Kitts Island.

Ectoparasites of bats and bat-associated pathogens are poorly studied in the Lesser Antilles Islands. We report on an 11-mo field study on Saint Kitts Island of bat populations, their associated ectoparasites, and pathogens. We report on five ectoparasite species, including four Streblidae (Diptera) and a Spinturnicidae (Acari).

Outcomes of type II endoleaks after endovascular abdominal aortic aneurysm (AAA) repair: a single-center, retrospective study.

Purpose: This study aims to determine incidence and outcomes of type II endoleaks (T2E) after endovascular abdominal aortic aneurysm repair (EVAR).

Methods: A retrospective review of procedural angiograms, computed tomography angiography, and medical records of 202 patients who underwent EVAR with the Gore Excluder stent graft was performed to determine presence and outcomes of T2E.

Results: Median follow-up time for 163 patients meeting inclusion criteria [136 males (83%)] was 24.
