AHI Outcomes Are Superior after Upper Airway Reconstructive Surgery in Adult CPAP Failure Patients.

Objective: This study aims to evaluate Apnea-Hypopnea Index (AHI) outcomes of upper airway adult obstructive sleep apnea (OSA) reconstructive surgery, as compared with outcomes of suboptimal continuous positive airway pressure (CPAP) therapy, in response to reviews claiming unreliable surgical AHI reduction.

Study Design: Prospective cohort study.

Setting: Single-surgeon series at medical centers within Wollongong, Australia.

Rare presentation of Rosai-Dorfman disease mimicking a cervical intramedullary spinal cord tumor.

Background: Rosai-Dorfman disease, or sinus histiocytosis with massive lymphadenopathy, is a rare, benign, lymphoproliferative disorder that commonly manifests as a massive painless cervical lymphadenopathy with associated fever and weight loss. Central nervous system involvement is extremely rare, and cervical spinal cord manifestation has not been reported.

Methods: A 76-year-old man presented with a 10-week history of right hemiparesis.
