Sleep medecine

OBJECTIVES: We aimed to assess sleep quality of Tunisian medical students during home confinement due to the COVID-19 pandemic, and to analyze the relationship between sleep quality and sociodemographic, clinical, confinement-related and psychological variables. METHODS: A correlational cross-sectional study was conducted from April 11th to May 3rd 2020. Medical students who have been in home confinement and who accepted to participate in an online survey were targeted...

QUESTION: A 12-year-old child underwent adenotonsillectomy for treatment of obstructive sleep apnea (OSA) but continues to snore at night and struggles with attentiveness at school. The child's parent uses a continuous positive airway pressure (CPAP) machine at night and wonders whether the same therapy could be used in children. ANSWER: Unlike in adults, pediatric OSA is commonly related to adenotonsillar hypertrophy and is often amenable to treatment with adenotonsillectomy...

Most of the continuous positive airway pressure (CPAP) devices currently in use allow telemonitoring of observance, leaks and the apnoea-hypopnoea index (AHI). La Société française de recherche et de médecine du sommeil (SFRMS) and La Société de pneumologie de langue française (SPLF) workgroup offer to CPAP prescribers and to home care providers a scientific document which has the following purposes: to underline the relevance of the telemonitoring of leaks and the AHI, to define alert thresholds, to describe the principal mechanisms generating excessive leaks and high AHI, and to propose a diagnostic algorithm...

There are in France several millions of shift-workers and night-workers (20 to 25% of employees). These workers are therefore subject to variations in their working and rest schedules. These regular schedule changes are associated with repeated desynchronization of circadian biological clock. The negative impacts on sleep are insomnia, drowsiness, and reduced sleep time in 24hours. There is also a proven effect on the occurrence of a metabolic syndrome, with a likely effect on obesity, type 2 diabetes, blood pressure and coronary artery disease...

Night work is not only a work performed at night. It has also to be considered as a specifically organized work with its own duties and moving tasks in a different relational context. Primary preventive assessments regarding work schedules and occupational associated constraints have to be considered beside family potential consequences. Taking account of the consensually accepted impact of night-shift work on health, particularly on sleep, we recommend an annual medical visit for night-shift workers. We also recommend to declare the night shift diseases to the Regional committee of occupational diseases via the "alinea 4"...

Circadian rhythm sleep disorders (CRSD) result from a disturbed endogenous clock (intrinsic CRSD) or from a misalignment between the biological clock and an imposed environment (extrinsic CRSD). Among intrinsic CRSD, one distinguishes the delayed sleep-wake phase disorder, the advanced sleep-wake phase disorder, the irregular sleep-wake rhythm disorder and the non-24-hour sleep-wake rhythm disorder. Shift work disorder, jet lag disorder and circadian sleep-wake disorder not otherwise specified are extrinsic CRSD...

Circadian rhythm sleep-wake disorders are characterized either by sleep schedules that do not correspond to the usual schedules usually imposed by the light/dark cycle and by socio-professional activities, or by an unusual number of sleep episodes 24h. These two anomalies of the sleep-wake cycle are caused by an alteration of the circadian system or its mechanisms of entraining. The clinician has various tools that will confirm the diagnosis of circadian rhythm sleep-wake disorders. These diagnostic tools determine the alteration of the circadian system by generally estimating the circadian phase or else confirm the misalignment of sleep relative to the external environment...

The objective of this study was to develop a shared-care model to enable primary-care physicians to participate more fully in meeting the complex, multidisciplinary healthcare needs of patients with multiple sclerosis (MS). DESIGN: The design consisted of development of consensus recommendations and a shared-care algorithm. PARTICIPANTS: A working group of 11 Canadian neurologists involved in the management of patients with MS were included in this study. MAIN MESSAGE: The clinical management of patients with multiple sclerosis is increasing in complexity as new disease-modifying therapies (DMTs) become available, and ongoing safety monitoring is required...

Gambiense Human African Trypanosomiasis (HAT), or sleeping sickness, is a vector-borne disease affecting largely rural populations in Western and Central Africa. The main method for detecting and treating cases of gambiense HAT are active screening through mobile teams and passive detection through self-referral of patients to dedicated treatment centres or hospitals. Strategies based on active case finding and treatment have drastically reduced the global incidence of the disease over recent decades. However, little is known about the coverage and transmission impact of passive case detection...

OBJECTIFS: Nous exposons un recueil de 2 cas cliniques montrant les différences de thérapeutiques entre un syndrome d'apnée du sommeil avec Hypertension artérielle systémique seule versus un autre cas de syndrome d'apnée du sommeil avec à la fois une hypertension artérielle systémique et une hypertension pulmonaire. le suivi tant clinique qu'écho-cardiographique du syndrome d'apnée du sommeil bien que parait simple, cache de multiples pièges qu'il faut savoir les rechercher d'une façon méthodique...

The Drugs for Neglected Diseases initiative (DNDi), with headquarters in Geneva, is a non-profit drug research and development (R&D) organization and Product Development Partnership (PDP) which was established in 2003 by 7 founding organizations such as Médecins Sans Frontières (MSF), the Pasteur Institute, The Specific Programme for Research and Training in Tropical Diseases (WHO-TDR), etc. DNDi has worked mainly on the development of new treatments for neglected tropical diseases (NTDs), which is difficult to achieve under market economy conditions...

BACKGROUND: Mumbai has a population of 21 million, and an increasingly recognised epidemic of drug-resistant tuberculosis (DR-TB). OBJECTIVE: To describe TB infection control (IC) measures implemented in households of DR-TB patients co-infected with the human immunodeficiency virus (HIV) under a Médecins Sans Frontières programme. METHODS: IC assessments were carried out in patient households between May 2012 and March 2013. A simplified, standardised assessment tool was utilised to assess the risk of TB transmission and guide interventions...

Since 1 July 2012, as a result of a labour arbitration ruling in the province of Quebec and the subsequent agreement negotiated by the Fédération des médecins résidents du Québec, all 3,400 medical residents training in Quebec have been on a 16-hour duty schedule for in-house calls. This is a major change within medical teaching sites, as well as a professional and educational challenge for physicians-in-training and their supervisors. The Quebec ruling now raises similar issues for all medical residents in Canada because of its legal basis, namely the Canadian Charter of Rights and Freedoms...

In medical humanitarian assistance, the diagnosis of diseases plays a crucial role. Laboratory investigations are one of the main diagnostic tools utilized in Médecins Sans Frontières' (MSF) programs. Currently MSF supports and/or operates more than 130 laboratories in approximately 45 countries. The variety of analysis offered depends largely on the context of the program and the availability of context adapted tools and ranges from sophisticated laboratories specializing in tuberculosis culture to small laboratories within a primary health care program or operating as mobile clinics...

BACKGROUND: Active case detection through mass community screening is a major control strategy against human African trypanosomiasis (HAT, sleeping sickness) caused by T. brucei gambiense. However, its impact can be limited by incomplete attendance at screening sessions (screening coverage) and diagnostic inaccuracy. METHODS: We developed a model-based approach to estimate the true prevalence and the fraction of cases detected during mass screening, based on observed prevalence, and adjusting for incomplete screening coverage and inaccuracy of diagnostic algorithms for screening, confirmation and HAT stage classification...

BACKGROUND: Algorithms to diagnose gambiense human African trypanosomiasis (HAT, sleeping sickness) are often complex due to the unsatisfactory sensitivity and/or specificity of available tests, and typically include a screening (serological), confirmation (parasitological) and staging component. There is insufficient evidence on the relative accuracy of these algorithms. This paper presents estimates of the accuracy of five algorithms used by past Médecins Sans Frontières programmes in the Republic of Congo, Southern Sudan and Uganda...

BACKGROUND: Human African trypanosomiasis (HAT), or sleeping sickness, is a fatal neglected tropical disease if left untreated. HAT primarily affects people living in rural sub-Saharan Africa, often in regions afflicted by violent conflict. Screening and treatment of HAT is complex and resource-intensive, and especially difficult in insecure, resource-constrained settings. The country with the highest endemicity of HAT is the Democratic Republic of Congo (DRC), which has a number of foci of high disease prevalence...

BACKGROUND: Children with human African trypanosomiasis (HAT) present with a range of generally non-specific symptoms. Late diagnosis is frequent with often tragic outcomes. Trypanosomes can infect the foetus by crossing the placenta. Unequivocal cases of congenital infection that have been reported include newborn babies of infected mothers who were diagnosed with HAT in the first 5 days of life and children of infected mothers who had never entered an endemic country themselves. METHODS: This review systematically summarizes the literature on the vertical transmission of HAT, to our knowledge for the first time...

BACKGROUND: Sleep disturbances are frequently reported in the older adult population and benzodiazepines are the drugs most often prescribed to treat these problems. Nearly 25% of the older adult population uses these drugs and 83% of benzodiazepine users report sleep problems. Although the Collège des Médecins du Québec suggests a maximum length of use of 3 months, according to most studies the mean length of benzodiazepine use is longer. The goal of this study was to document the association between length of benzodiazepine use and sleep quality as reported by adults 65 years older and over...
