[Physiopathology of obstructive sleep apnea syndrome].

An excellent grasp of the physiopathology of obstructive sleep apnea syndrome (OSAS) is essential to understanding its diagnostic and therapeutic modalities. A systematic review of the literature was performed on data specific to humans. Two aspects are involved: on one hand, the mechanisms contributing to intermittent obstruction of the upper airways (UA) during sleep and, on the other hand, the impact of this obstruction, e.

International consensus (ICON) on the ENT role in diagnosis of obstructive sleep apnea syndrome.

During the 2017 IFOS ENT World Congress, an international expert panel was asked to clarify the role of ENT in the diagnosis process of the obstructive sleep apnea syndrome (OSA) in adults around the world. OSA is a major public health issue throughout the world. OSA is a highly prevalent disease with heavy clinical, social and economical outcomes.

Obstructive sleep apnoea syndrome: comparison between polysomnography and portable sleep monitoring based on jaw recordings.

Introduction: Obstructive sleep apnoea syndrome (OSAS) constitutes a new major public health problem because of its several pathophysiologic consequences such as cognitive disorders, excessive daytime sleepiness with risks of traffic accidents, cardiovascular implications, and decrease of quality of life. The necessity of a gold-standard polysomnography to ensure an accurate diagnosis implies an expensive, technical and time-consuming examination. Thus, it seems logical to develop new systems so as to diagnose SAS and to make it possible to detect apnoeas/hypopnoeas easily during sleep even at home.

Sinonasal involvement in sarcoidosis: a case-control study of 20 patients.

We conducted a retrospective single-center study to describe the clinical features of sinonasal sarcoidosis (SNS) and to determine whether SNS is associated with a particular clinical phenotype of sarcoidosis. Twenty patients with histologically proven SNS (men/women, 7/13; mean age, 32 +/- 9 yr) were compared with control patients with sarcoid but without sinonasal (SN) involvement. Each patient was matched with 2 controls for the date of admittance in our institution.

Transitory increased blood pressure after upper airway surgery for snoring and sleep apnea correlates with the apnea-hypopnea respiratory disturbance index.

A transitory increase in blood pressure (BP) is observed following upper airway surgery for obstructive sleep apnea syndrome but the mechanisms implicated are not yet well understood. The objective of the present study was to evaluate changes in BP and heart rate (HR) and putative factors after uvulopalatopharyngoplasty and septoplasty in normotensive snorers. Patients (N = 10) were instrumented for 24-h ambulatory BP monitoring, nocturnal respiratory monitoring and urinary catecholamine level evaluation one day before surgery and on the day of surgery.
