[Obstructive sleep apnea syndrome and cardiovascular diseases].

Obstructive sleep apnoea syndrome is due to pharyngeal obstruction of inspiratory airflow with preservation of thoraco-abdominal respiratory movements. This disease has been described for about thirty years, but is now the subject of growing interest. According to the increasingly abundant literature on this subject, OSAS is associated with essentially cardiovascular morbidity and mortality (systemic hypertension, pulmonary hypertension, heart failure, coronary heart disease, arrhythmias, cerebral vascular accidents and sudden death).

Decreased autologous rosette-forming T lymphocytes in alcoholic cirrhosis: absence of correlation with other T cell markers and with delayed cutaneous hypersensitivity.

Autologous rosette-forming T lymphocytes were enumerated in periphal blood of patients with established alcoholic cirrhosis and compared with T lymphocytes forming rosettes with sheep red blood cells (total and 'active' rosette-forming cells; RFC). Decreased autologous RFC was the most frequent T lymphocyte abnormality observed in 43 patients and was shown to occur even in patients with normal total and 'active' RFC. No correlation was found between autologous RFC and total or 'active' RFC.
