Polysomnographic Oxygen Saturation Findings for Preteen Children versus Adolescents.

Objective Home oximetry is commonly used to screen for obstructive sleep apnea (OSA) in children; however, normal oxygen desaturation levels by disease severity are not well known. It was our objective to determine if oxygen saturation levels differed by OSA severity category in children and if these differences were similar for preteen children and adolescents. Study Design Retrospective case series of children undergoing polysomnography from September 2011 to July 2015.

Hearing loss in Down Syndrome revisited - 15 years later.

Objective: In 2001, the senior authors published a study investigating hearing loss in young children (ages 11 months to 3.8 years) with Down Syndrome (DS). We re-visit this same study population to review current audiologic status, the incidence of pressure equalization tube (PET) placement(s), and rate of tympanic membrane (TM) perforations.

Hearing loss progression and contralateral involvement in children with unilateral sensorineural hearing loss.

Objectives: We undertook this study to determine the rate of hearing loss progression in the affected ear of children with unilateral sensorineural hearing loss and without an enlarged vestibular aqueduct, and the rate of new-onset hearing loss in the contralateral ear.

Methods: We searched the database at our pediatric tertiary care center to identify patients who met the inclusion criteria, examining demographic variables, audiometric data, and presumptive causes.

Results: We identified 198 patients.

Audiologic and temporal bone imaging findings in patients with sensorineural hearing loss and GJB2 mutations.

Objectives/hypothesis: Our objectives were to determine genotype-phenotype correlations in patients with sensorineural hearing loss (SNHL) who undergo testing for GJB2 mutations and to examine the relationship of temporal bone anomalies seen on computed tomography (CT) and GJB2 mutations.

Study Design: We conducted a retrospective review of all children diagnosed with SNHL and who underwent GJB2 testing from 1997 to 2006.

Results: Of 840 patients, 146 (17.
