Annotated Bibliography, Oct 2014

The following is a sampling of editorials and papers published in response to the ARUBA trial (listed as number 1 below). I can summarize the critics by noting that the nicest thing anyone said about the trial was that that the authors are to be “commended” for at least trying….followed by elaboration of multiple, and presumably fatal, study design flaws. The point, counter-point by Drs. Mohr and Amin-Hanjani is particularly interesting since it puts it into perspective from a specific patient standpoint.

Should scientists care about the Kardashian Index?

Knowing of my interest in professional use of social media, especially Twitter, my friend and mentor, Dr Pratik Mukherjee, shared with me an interesting column from the Science magazine. I found it an interesting easy read. It can be thought provoking regardless of how you feel about social media use.

Jua You, a news intern at Science, has published a column on September 17th issue of Science magazine. She has looked at the Kardashian Index (K-index) for the “top 50 science stars of Twitter”. The controversial K-index was recently proposed by Genomicist Neil Hall, and is the ratio … Continue reading >>

Use of Non-Echo-Planar Diffusion-Weighted MR Imaging for the Detection of Cholesteatomas in High-Risk Tympanic Retraction Pockets

Fellows’ Journal Club September 2014

(3 of 3)

HASTE DWI was used to examine 16 patients before cholesteatoma surgery and the findings were compared with those seen intraoperatively. HASTE DWI showed 90% sensitivity, 100% specificity, 100% positive predictive value, and 85.7% negative predictive value in this group of patients. Only 1 false-negative finding in an infected cholesteatoma occurred.

EIC signature

Abstract

BACKGROUND AND PURPOSE
Non-echo-planar DWI MR imaging (including the HASTE sequence) has been shown to be highly sensitive and specific for large cholesteatomas. The purpose of this study was to determine the diagnostic accuracy of HASTE DWI for the detection of … Continue reading >>

Screening CT Angiography for Pediatric Blunt Cerebrovascular Injury with Emphasis on the Cervical “Seatbelt Sign”

Editor’s Choice September 2014

(3 of 3)

The authors investigated the significance of several clinical and imaging risk factors, most specifically the “cervical seatbelt sign,” in the anterior neck in pediatric patients with suspected blunt cerebrovascular injury as seen by CTA. They found that this common indication for neck CTA was not associated with blunt cerebrovascular injury. With the exception of Glasgow Coma Scale score, no single risk factor was statistically significant in predicting vascular injury.

Abstract

BACKGROUND AND PURPOSE
There are no standard screening guidelines to evaluate blunt cerebrovascular injury in children. The purpose of this retrospective study was
