Dietary supplement comprised of β-carotene, vitamin C, vitamin E, and magnesium: failure to prevent music-induced temporary threshold shift.

This study examined potential prevention of music-induced temporary threshold shift (TTS) in normal-hearing participants. A dietary supplement composed of β-carotene, vitamins C and E, and magnesium was assessed using a randomized, placebo-controlled, double-blind study design. Dosing began 3 days prior to the music exposure with the final dose consumed approximately 30-min pre-exposure.

Improved behavior after adenotonsillectomy in children with higher and lower IQ.

Objectives: To examine whether high intellectual ability, in comparison to average or lower performance, reflects the consequences of sleep-disordered breathing and limits behavioral benefit observed 6 months after adenotonsillectomy.

Methods: Children aged 3-12 years (n=147) recruited from otolaryngology practices at two hospitals and assessed with Conners' Parent Rating Scales and an age range-appropriate intellectual measure, the Stanford-Binet Intelligence Scale at baseline and 6 months after clinically-indicated adenotonsillectomy. Subjects were classified as having high (IQ≥110), average (90≤IQ<110), or low (IQ<90) cognitive ability.

Analysis of High-, Intermediate-, and Low-Volume Surgeons When Performing Hysterectomy for Uterovaginal Prolapse.

Objectives: To determine if surgeon volume is associated with differences in the use of apical colpopexy and cystoscopy and in the rate of intraoperative complications during hysterectomy for prolapse.

Methods: We performed a multicenter retrospective review of hysterectomies done for uterovaginal prolapse at 4 hospital systems between January 1, 2008, and December 31, 2011. Low (≤10 cases)-, intermediate (11-49 cases)-, and high (≥50 cases)-volume surgeon groups for the 4-year period were established a priori.

Differences in Patterns of Preoperative Assessment Between High, Intermediate, and Low Volume Surgeons When Performing Hysterectomy for Uterovaginal Prolapse.

Objective: The aim of the study was to determine whether surgeon case volume is associated with preoperative evaluation of pelvic organ prolapse before a hysterectomy for uterovaginal prolapse including a complete objective evaluation of prolapse (Baden-Walker or Pelvic Organ Prolapse Quantification), an offer of nonsurgical options for therapy (pessary), and a preoperative assessment of urinary incontinence

Methods: We performed a multicenter retrospective review of hysterectomies done for uterovaginal prolapse at 4 hospital systems between January 1, 2008 and December 31, 2011. The number of hysterectomies per surgeon for 4 years was evaluated to establish low-volume (≤10 cases), intermediate-volume (11-49 cases), and high-volume (≥50 cases) groups. Rates of preoperative standardized prolapse evaluations, offer of pessary, and evaluation of stress urinary incontinence were determined by chart review of 15% of the hysterectomy cases.

Periodic leg movements during sleep in children scheduled for adenotonsillectomy: frequency, persistence, and impact.

Objective: The aim of this study was to assess the frequency and potential clinical impact of periodic leg movements during sleep (PLMS), with or without arousals, as recorded incidentally from children before and after adenotonsillectomy (AT).

Methods: Children scheduled for AT for any clinical indications who participated in the Washtenaw County Adenotonsillectomy Cohort II were studied at enrollment and again 6 months thereafter. Assessments included laboratory-based polysomnography, a Multiple Sleep Latency Test (MSLT), parent-completed behavioral rating scales, neuropsychological testing, and psychiatric evaluation.
