Hearing Loss in Children with 22q11.2 Deletion Syndrome.

Objectives: Hearing loss is considered common in children with 22q11.2 deletion syndrome (22q11.2DS), with a few prior studies reporting a 32%-78% prevalence; mild-moderate conductive hearing loss has been reported most commonly.

Weight Gain After Adenotonsillectomy in Children With Mild Obstructive Sleep-Disordered Breathing: Exploratory Analysis of the PATS Randomized Clinical Trial.

Importance: It is unknown whether adenotonsillectomy causes undesirable weight gain in children with mild obstructive sleep-disordered breathing (oSDB).

Objective: To compare changes in anthropometric measures in children with mild oSDB treated with adenotonsillectomy vs watchful waiting.

Design, Setting, And Participants: This was an exploratory analysis of the Pediatric Adenotonsillectomy Trial for Snoring (PATS) randomized clinical trial of adenotonsillectomy vs watchful waiting for mild oSDB (snoring with obstructive apnea-hypopnea index of <3 events/hour) that took place at 7 pediatric tertiary care centers across the US and included 458 children aged 3.

Multi-institutional Assessment of Otitis Media Epidemiology Using Real-world Data.

Objectives: To determine rates and risk factors of pediatric otitis media (OM) using real-world electronic health record (PEDSnet) data from January 2009 through May 2021.

Study Design: Retrospective cohort study.

Setting: Seven pediatric academic health systems that participate in PEDSnet.

Recurrent missense variant identified in two unrelated families with MPZL2-related hearing loss, expanding the variant spectrum associated with DFNB111.

MPZL2-related hearing loss is a rare form of autosomal recessive hearing loss characterized by progressive, mild sloping to severe sensorineural hearing loss. Thirty-five previously reported patients had biallelic truncating variants in MPZL2, with the exception of one patient with a missense variant of uncertain significance and a truncating variant. Here, we describe the clinical characteristics and genotypes of five patients from four families with confirmed MPZL2-related hearing loss.

Clinical Characteristics of Primary Snoring vs Mild Obstructive Sleep Apnea in Children: Analysis of the Pediatric Adenotonsillectomy for Snoring (PATS) Randomized Clinical Trial.

Importance: It is unknown whether children with primary snoring and children with mild obstructive sleep apnea (OSA) represent populations with substantially different clinical characteristics. Nonetheless, an obstructive apnea-hypopnea index (AHI) of 1 or greater is often used to define OSA and plan for adenotonsillectomy (AT).

Objective: To assess whether a combination of clinical characteristics differentiates children with primary snoring from children with mild OSA.
