[Cross-sectional study of school integration of asthmatic children in a general population sample].

Aims: Asthma is one of the most frequently encountered chronic illnesses in children. The aim of the present study was to investigate the problem of integration of asthmatic subjects at school by assessing the reactions of parents and teachers, and also by considering the medical aspects.

Population And Methods: A cross-sectional random study was carried out during autumn 1994 including 4,251 primary school children aged between five and 14 years, and including teachers from 188 classes and 26 schools in Grenoble and its inner suburbs.

[Giant thymic lipoma: anatomical, radiologic and clinical aspects].

We report the case of a 51-year-old man who presents with worsening dyspnea at exercise caused by a large thymic lipoma (6 kg). We present the clinical, radiological, and spiral CT scan features of this rare and benign tumor and correlate them with the pathologic findings.

Accuracy of oximetry for detection of respiratory disturbances in sleep apnea syndrome.

Study Objective: The cost and inconvenience of polysomnography make simplified techniques of screening desirable in the strategy of diagnosis of sleep apnea syndrome (SAS). We have evaluated, in a prospective study of 301 consecutive patients referred for suspected sleep disorders, an index (delta index) that detects apneic events by quantifying arterial oxygen saturation (SaO2) variability.

Setting: Regional sleep laboratory taking referrals from general practitioners and specialists.

Mechanism of gluconeogenesis inhibition in rat hepatocytes isolated after in vivo hypoxia.

Gluconeogenesis was studied in hepatocytes isolated from fasted rats submitted to 24 h of hypoxic exposure (inspired O2 fraction 0.1) or to room air. Hepatocytes from hypoxic rats compared with controls exhibited a lower gluconeogenic rate with lactate (5.
