[Evaluation of the risk of obstructive sleep apnea in patients awaiting general anesthesia in Burkina Faso].

Introduction: General anaesthesia and surgery increase morbidity and mortality in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) who are not known to have OSAHS and therefore not treated before surgery. The objective of this study is to evaluate the risk of OSAHS using the STOP-BANG questionnaire (SBQ) in patients undergoing general anaesthesia in Burkina Faso.

Material And Method: This is a cross-sectional study concerning patients having received pre-anaesthetic consultation from 1st July 2020 to 30th June 2021.

Auto-adjusted versus fixed positive airway pressure in patients with severe OSA: A large randomized controlled trial.

Background And Objective: Continuous positive airway pressure (CPAP) in the treatment of severe obstructive sleep apnoea (OSA) can be used in fixed CPAP or auto-adjusted (APAP) mode. The aim of this prospective randomized controlled clinical study was to evaluate the 3 month-efficacy of CPAP used either in fixed CPAP or APAP mode.

Methods: Eight hundred one patients with severe OSA were included in twenty-two French centres.

[Study about the prevalence of the obstructive sleep apnoea syndrome in Vietnam].

Introduction: Epidemiological studies on obstructive sleep apnoea syndrome (OSAS) in Asia, South East Asia in particular, are few. The EPSASIE study aimed to determine the prevalence of OSAS in an adult Vietnamese population and to describe its characteristics.

Methods: This is a prospective, observational, multicenter study.

[The effects of inhaled steroids withdrawal in COPD].

The key pathophysiological feature of chronic obstructive pulmonary disease (COPD) is an abnormal inflammatory bronchial reaction after inhalation of toxic substances. The priority is the avoidance of such toxic inhalations, but the use of anti-inflammatory drugs also seems appropriate, especially corticosteroids that are the sole anti-inflammatory drug available for this purpose in France. The risks associated with the prolonged use of these parenteral drugs are well known.

[The place of inhaled corticosteroids in COPD].

Introduction: Clinical trials have provided some evidence of a favorable effect of inhaled corticosteroids on the frequency of exacerbations and on the quality of life of patients with chronic obstructive pulmonary disease (COPD). In contrast, ICS have little or no impact on lung function decline and on mortality.

State Of The Art: Inhaled corticosteroids are recommended only in a minority of COPD patients, those with severe disease and repeated exacerbations and probably those with the COPD and asthma overlap syndrome.
