Presence of ipsilateral acoustic reflex artifact may result in clinical misidentification.

Objective: Upon calibration of a specific commercially available immittance device, an artifact was consistently measured in a calibration cavity when in ipsilateral acoustic reflex mode. These results were replicated in a controlled fashion, raising concerns about how clinical results might potentially be misinterpreted.

Design: Responses were measured from an Interacoustics Titan and Grason-Stadler Tympstar Pro immittance device coupled to a 0.

Relation of Ratio of Left Ventricular Ejection Fraction to Left Ventricular End-Diastolic Pressure to Long-Term Prognosis After ST-Segment Elevation Acute Myocardial Infarction.

Risk stratification of patients with ST-segment elevation acute myocardial infarction (STEMI) is suboptimal. We assessed the prognostic value of the left ventricular ejection fraction to left ventricular end-diastolic pressure (LVEF/LVEDP) ratio in patients with STEMI who underwent primary percutaneous coronary intervention (PPCI). The study included 1,283 patients with STEMI.

Binaural Interference: Quo Vadis?

The reality of the phenomenon of binaural interference with speech recognition has been debated for two decades. Research has taken one of two avenues; group studies or case reports. In group studies, a sample of the elderly population is tested on speech recognition under three conditions; binaural, monaural right and monaural left.

Auditory adaptation testing as a tool for investigating tinnitus origin: two patients with vestibular schwannoma.

Objective: To enhance the understanding of tinnitus origin by disseminating two case studies of vestibular schwannoma (VS) involving behavioural auditory adaptation testing (AAT).

Design: Retrospective case study.

Study Sample: Two adults who presented with unilateral, non-pulsatile subjective tinnitus and bilateral normal-hearing sensitivity.

Microbubble oscillations in capillary tubes.

In diagnostic medicine, microbubbles are used as contrast agents to image blood flow and perfusion in large and small vessels. The small vessels (the capillaries) have diameters from a few hundred micrometers down to less than 10 μ m. The effect of such microvessels surrounding the oscillating microbubbles is currently unknown, and is important for increased sensitivity in contrast diagnostics and manipulation of microbubbles for localized drug release.
