Article Abstract
Background: While hydroxyurea is the mainstay of treatment for many of the comorbidities associated with sickle cell disease, its effect on obstructive sleep apnea has not been fully investigated. The purpose of this project is to help characterize the effects of hydroxyurea on obstructive sleep apnea in children with sickle cell disease and determine its therapeutic role in the condition.
Methods: Chart review was conducted on two pediatric patients with sickle cell disease who experienced resolution of obstructive sleep apnea following hydroxyurea administration.
Results: After undergoing approximately 11 months of hydroxyurea therapy, sleep apnea symptoms improved and obstructive sleep apnea resolution was confirmed by repeat polysomnography in both cases. This resolution was largely secondary to a reduction in the obstructive component of the apnea hypopnea index, highlighting a previously unreported association.
Conclusions: As adenotonsillectomy is associated with significant risks in patients with sickle cell disease, it appears reasonable to consider a period of observation for improvement of obstructive sleep apnea following hydroxyurea administration rather than directly proceeding with surgery.

Objectives: This non-randomised clinical study aimed to identify the phenotypic characteristics that distinguish responders from non-responders. Additionally, it sought to establish a predictive model for treatment response to obstructive sleep apnoea (OSA) using mandibular advancement devices (MAD), based on the analysed phenotypic characteristics.
Material And Methods: This study, registered under identifier NCT05596825, prospectively analysed MAD treatment over 6 years using two-piece adjustable appliances according to a standardised protocol.

Purpose: Obstructive sleep apnea (OSA) affects up to 936 million adults globally and is linked to significant health risks, including neurocognitive impairment, cardiovascular diseases, and metabolic conditions. Despite its prevalence, OSA remains largely underdiagnosed. This study aimed to enhance OSA awareness and risk assessment using the STOP-Bang questionnaire in a telemedicine format.

: Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder characterized by intermittent upper airway obstruction, leading to significant health consequences. Traditional diagnostic methods, such as polysomnography, are time-consuming and resource-intensive. : This study explores the potential of proton-transfer-reaction mass spectrometry (PTR-MS) in identifying volatile organic compound (VOC) biomarkers for the non-invasive detection of OSA.
