Centre d'investigation et de recherche sur le sommeil, Centre hospitalier universitaire vaudois, 1011 Lausanne.

Obstructive sleep apnea (OSA) is a frequent pathology with clinical implications. Its comorbidity with the complaint of insomnia is common, and has been increasingly studied in recent years, due to the multiple negative synergies highlighted by these two conditions, notably on all-cause excess mortality, cardiovascular risk, quality of life and sleep, as well as mental health. This comorbidity between insomnia and sleep apnea has recently been referred to as COMISA («co-morbid insomnia and sleep apnea»).

Adaptive servo-ventilation (ASV) effectively treats sleep-disordered breathing, including central sleep apnea (CSA) and coexisting obstructive sleep apnea (OSA). The prospective, multicenter European READ-ASV (Registry on the Treatment of Central and Complex Sleep-Disordered Breathing with Adaptive Servo-Ventilation) registry investigated the effects of first-time ASV therapy on disease-specific quality of life (QoL). The registry enrolled adults with CSA with or without OSA who had ASV therapy prescribed between September 2017 and March 2021.

Whole-night sleep electroencephalogram (EEG) is plagued by several types of large-amplitude artifacts. Common approaches to remove them are fraught with issues: channel interpolation, rejection of noisy intervals, and independent component analysis are time-consuming, rely on subjective user decisions, and result in signal loss. Artifact Subspace Reconstruction (ASR) is an increasingly popular approach to rapidly and automatically clean wake EEG data.

Dysphagia is a frequent complication in neurologically impaired patients, which can lead to aspiration pneumonia and thus prolonged hospitalization or even death. It is essential therefore, to detect and assess dysphagia early for best patient care. Fiberoptic endoscopic and Videofluoroscopy evaluation of swallowing are the gold standard exams in swallowing studies but neither are perfectly suitable for patients with disorders of consciousness (DOC).

  • Adaptative servo-ventilation (ASV) is effective in treating central sleep apnea but its real-world usage and effects on quality of life are not well understood.
  • This study followed 801 patients prescribed ASV from 2017 to 2021, analyzing their symptoms, quality of life (QoL), and reasons for ASV therapy.
  • Common reasons for ASV usage included persistent CSA and CSA associated with cardiovascular disease, with many patients showing severe symptoms and low quality of life scores at baseline. One-year follow-up data will help assess the impact of ASV on their QoL and overall health outcomes.*

Hallermann-Streiff syndrome (HSS) is a rare congenital syndrome with different anomalies including midface hypoplasia, beak nose and micrognathia. The upper airways narrowness can lead to severe respiratory complications such as obstructive sleep apnoea syndrome (OSAS), particularly in infancy. The management of these severe OSAS is difficult and poorly documented in literature.

Stroke prediction is a key health issue for preventive medicine. Atrial fibrillation (AF) detection is well established and the importance of obstructive sleep apneas (OSA) has emerged in recent years. Although autonomic nervous system (ANS) appears strongly implicated in stroke occurrence, this factor is more rarely considered.

Benzodiazepines have proven to be highly effective for treating insomnia and anxiety. Although considered safe when taken for a short period of time, a major risk-benefit dilemma arises in the context of long-term use, relating to addiction, withdrawal symptoms, and potential side effects. For these reasons, benzodiazepines are not recommended for treating chronic sleep disorders, anxiety disorders, nor for people over the age of 65, and withdrawal among long-term users is a public health issue.

Neurostimulation of the hypoglossal nerve is a new alternative treatment to CPAP (Continuous Positive Airway Pressure) for patients with moderate-to-severe OSAS (Obstructive Sleep Apnea Syndrome) with anteroposterior pharyngeal obstruction visualized during a Drug Induced Sleep Endoscopy (DISE). Implantation and follow-up are performed at the CHUV with the collaboration between the SAOS-ronchopathie unit, the maxillofacial and dental surgery division and the center for investigation and research on sleep (CIRS). In this article, we present the technique, its indication and the outcomes through a recent review of the literature.

Obstructive sleep apnea syndrome (OSAS) and arterial hypertension (HT) are two frequent, often concomitant diseases, who are both associated with an increased cardiovascular risk. In the last years, an association between these two entities has been established. The purpose of this article is to review the current knowledge about the link between HT and OSAS, the pathophysiological mechanisms involved in the common genesis of the two conditions and the characteristics suggesting an underlying OSAS in a hypertensive subject.

Objective: Subjective health complaints (SHC) are frequent in musicians. These complaints may be particularly distressing in this population because they are performance relevant. This paper aims at testing a model positing that (a) perseverative cognition (PC) predicts sleep duration/quality, (b) sleep duration/quality predicts SHC and (c) mood is a mediator of these associations.

[Sleep apnea : diagnostic and therapeutic modalities in case of failure of the CPAP].

Rev Med Suisse

October 2018

Service d'ORL et de chirurgie cervico-faciale, CHUV, 1011 Lausanne.

Obstructive sleep apnea (OSA) is a sleep disorder that affects 49 % of men and 23% of women over 40 years old. CPAP is currently the treatment of choice for severe OSAS, but there are mild to moderate cases of OSAS with poor compliance or intolerance to CPAP, for which alternative treatments should be considered. In this article, we present a tool for evaluation of the upper airways, the DISE (Drug-induced sleep endoscopy), the OAM (mandibular advancement device), the bimaxillary advancement osteotomy, the hypoglossal nerve stimulation and the positional treatment.

Sleep is characterized, from a behavioral point of view, by a physical quiescence. However, sleep can be disrupted by movements which can occur before falling asleep, during the sleep-wake transition, or during sleep. Some of these movements may be considered quasi-physiological because they are very common in the general population and have little or no clinical impact.

Snoring, chronic rhinitis and fragmentation of sleep are common symptoms in pregnancy, especially in the third trimester. The prevalence of obstructive sleep apnea is also increased in pregnant women and can be associated with pregnancy induced hypertension, preeclampsia and diabetes mellitus. The fetus is as well exposed to a higher risk of prematurity and intra-uterine growth restriction.

[Epidemiology, risk factors and phenotypes of sleep breathing disorders].

Presse Med

April 2017

Centre hospitalier universitaire Vaudois, centre d'investigation et de recherche sur le sommeil, rue du Bugnon, BH06-204, 1011 Lausanne, Suisse. Electronic address:

Recent epidemiological studies show that the prevalence of sleep-disordered breathing seems to be higher than previously estimated in the middle to older aged general population with approximatively 49% of men and 23% of women being affected. This higher than expected prevalence of sleep-disordered breathing seems to be due to the high sensitivity of current recording techniques and to the new and more inclusive definition of respiratory events (hypopnea definition in particular). Male sex, age, and truncal obesity (large neck girth, high waist to hip ratio) are the main risk factors for sleep-disordered breathing.
