Association between Smoking and 30-Day Outcomes in Otologic Surgery.

Objective: To determine the effect of current smoking status on 30-day postoperative adverse events in patients undergoing otologic surgery.

Study Design: Retrospective cohort study.

Setting: Database of the American College of Surgeons National Surgical Quality Improvement Program from 2006 to 2016.

Modification of Osseointegrated Device Parameters to Improve Speech in Noise and Localization Ability: Clinical Recommendations.

Objective: To determine how best to modify osseointegrated (OI) devices or environmental settings to maximize hearing performance.

Study Design: Prospective cohort study.

Setting: Tertiary referral center.

Outcomes review of modern hearing preservation technique in cochlear implant.

Introduction: Preservation of residual hearing in cochlear implantation is a main concern for patients and otologists. New electrode arrays as well as development of minimally invasive technique have allowed the expansion of indication criteria for cochlear implantation. The loss of residual low-frequency hearing is thought to be the result of many factors.

Exposure of Daphnia magna to trichloroethylene (TCE) and vinyl chloride (VC): evaluation of gene transcription, cellular activity, and life-history parameters.

Trichloroethylene (TCE) is a ubiquitous contaminant classified as a human carcinogen. Vinyl chloride (VC) is primarily used to manufacture polyvinyl chloride and can also be a degradation product of TCE. Very few data exist on the toxicity of TCE and VC in aquatic organisms particularly at environmentally relevant concentrations.

OCTO "Outcomes of cochlear implant for the octogenarians: audiologic and quality-of-life".

Objective: The aim of this study is to assess the impact on quality of life, hearing performance, and surgical complications among patients aged 80 years and older, at the time of cochlear implantation.

Design: Retrospective chart review and quality of life assessment.

Setting: Tertiary referral center.

A multimodality vascular imaging phantom with fiducial markers visible in DSA, CTA, MRA, and ultrasound.

The objective was to design a vascular phantom compatible with digital subtraction angiography, computerized tomography angiography, ultrasound and magnetic resonance angiography (MRA). Fiducial markers were implanted at precise known locations in the phantom to facilitate identification and orientation of plane views from three-dimensional (3-D) reconstructed images. A vascular conduit connected to tubing at the extremities of the phantom ran through an agar-based gel filling it.
