Cecal insertion and withdrawal times with wide-angle versus standard colonoscopes: a randomized controlled trial.

Background & Aims: The aim of this study was to see if a 170 degrees angle of view (wide angle [WA]) colonoscope allowed faster withdrawal without decreasing adenoma detection.

Methods: Eight colonoscopists at 2 institutions participated in the study. Patients were randomized so that each colonoscopist performed 50% of the exams with a 160 series (140 degrees angle of view; standard [ST]) colonoscope and 50% with a prototype 160 series colonoscope with a 170 degrees angle of view (WA instrument).

Cochlear temperature correlates with both temporalis muscle and rectal temperatures. Application for testing the otoprotective effect of hypothermia.

Conclusions: During systemic hypothermia, the internal temperature of the rat cochlea correlates best with the temporalis muscle and rectal temperatures. These positive correlations will be used in future studies to assess the efficacy of mild and moderate hypothermia to protect hearing against the progressive loss caused by electrode insertion in a clinically relevant model of cochlear implantation trauma.

Objective: To monitor the internal temperature of the cochlea during induced systemic hypothermia using a reference tissue instead of an internal cochlear temperature probe.

Evaluation of hearing and auditory nerve function by combining ABR, DPOAE and eABR tests into a single recording session.

In this article, we describe an efficient method for testing both auditory receptor and auditory nerve function in a single recording session. Auditory receptor function is tested in response to pure tone, tone burst and click acoustic stimuli (i.e.

Small Bowel Ischemia.

Small bowel ischemia is a relatively uncommon disorder requiring prompt recognition and aggressive management if significant morbidity and mortality are to be averted. The pathophysiology of the ischemic event usually will determine the management approach used. Factors to be considered include whether the ischemia is the consequence of arterial or venous occlusive disease; the cause and nature of the ischemia (ie, a consequence of arterial spasm, inflammation, complete or incomplete occlusion); whether the occlusion is the result of an embolus or thrombosis; the preexistence and degree of development of arterial collateral channels; and the existence and extent of comorbid conditions.
