INTRODUCTION Acute hypercapnic respiratory failure (AHRF) is a serious condition observed in some patients with sleep apnea-hypopnea syndrome (SAHS). The objective of the present study was to study the clinical characteristics of SAHS patients who develop AHRF and their prognosis. PATIENTS AND METHOD A total of 70 consecutive SAHS patients who survived an AHRF episode and 70 SAHS patients pai...

Abstract Introduction Obstructive sleep apnea (OSA) is typically treated with positive airway pressure (PAP) therapy in symptomatic patients ≥ 5 obstructive respiratory events (apneas, hypopneas or effort related arousals) per hour of sleep. In this case, we present a patient severe OSA isolated to REM who demonstrated significant improvement on PAP therapy, despite an overall apnea-hypopnea in...

There is a growing interest in photoplethysmography (PPG) for the continuous monitoring of cardio-respiratory signals by portable instrumentation aimed at early diagnosis cardiovascular diseases. In this context, it conceivable that PPG sensors working different wavelengths simultaneously can optimize identification apneas and quantification associated heart-rate changes or other parameters dep...

Aim: Complex sleep apnea syndrome (CompSAS) is characterized by the onset of central apneas or a Cheyne-Stokes breathing pattern in some patients with obstructive sleep apnea syndrome (OSAS) who were treated with continuous positive airway pressure (CPAP). The etiology of CompSAS is unclear, but derangement of respiratory control has been proposed. We sought to compare clinical and polysomnogra...

Adenoidectomy is a commonly performed surgery in children, even though its effectiveness is still under investigation. However, in children with risk factors such as age under 3 years old, associated comorbidities, or severe obstructive sleep apneas, a high postoperative respiratory morbidity is possible. We report the case of a 15-month-old boy with Noonan syndrome and a complex clinical histo...

A case report is presented which demonstrates the effectiveness of comprehensive orthodontic treatment combined with orthognathic surgery in the correction of malocclusion and reduction in the sequelae of Obstructive Sleep Apnea (OSA). The patient's severe OSA was improved to very mild as evaluated by full overnight polysomnogram. The orthodontic treatment included the expansion of both dental ...
