STUDY OBJECTIVE To assess the effect of 1 year of therapy for sleep apnea syndrome (SAS) combining domiciliary nasal-continuous positive airway pressure (N-CPAP) and attempted weight loss on the severity of disease and to evaluate the potential for weaning from continuous positive airway pressure (CPAP). METHODS AND PROCEDURES Ninety-five patients having(More)
STUDY OBJECTIVES Reports on the reproducibility of apnea-hypopnea indexes (AHIs) across sequential polysomnography (PSG) sessions are conflicting, leading to a lack of clear recommendations on the optimal use of this technique: is one night of monitoring sufficient or is a second night required in order to safely reject the diagnosis? DESIGN Retrospective(More)
OBJECTIVE To investigate the dynamics of the synchronization between heart rate variability and sleep electroencephalogram power spectra and the effect of sleep apnea-hypopnea syndrome. METHODS Heart rate and sleep electroencephalogram signals were recorded in controls and patients with sleep apnea-hypopnea syndrome that were matched for age, gender,(More)
In patients with hematological malignancies and splenomegaly, acute abdominal pain in the left upper quadrant is highly suspicious of splenic disease (i.e., hematoma, infarction, or rupture). We report the case of a patient with chronic myelogenous leukemia and splenomegaly who presented an unusual abdominal condition causing pain in the left upper(More)
Static lung volumes, CO-lung transfer, airway resistance, maximal expiratory flows and lung elastic properties were studied in 29 children and adolescents 1-10 years after recovery from acute rheumatic fever. There were essentially no changes in lung function even in the subjects with a residual valvular disease. The only abnormality was a tendency for the(More)
STUDY OBJECTIVES Auto-continuous positive airway pressure (CPAP) has been reported to have no more efficacy than constant CPAP in unselected patients with sleep apnea hypopnea syndrome (SAHS). The aim of this study was to evaluate patients judged to be good candidates for auto-CPAP because of a high within-night variability in pressure requirement. DESIGN(More)
This study was designed to investigate the reproducibility and clinical relevance of several lung function and exercise test indices in a sample of patients with stable severe chronic obstructive pulmonary disease (COPD). Twenty subjects (ages 67.8 +/- 2.0 years, forced expiratory volume in 1s, [FEV1] 39.7 +/- 2.8% predicted) receiving conventional medical(More)
Twenty patients with stable COPD (mean age 67.8 yr; mean FEV1 1.08 1), all limited by ventilation at maximum exercise, were randomly allocated after a four week control period, to an eight week programme of either inspiratory resistive training (IRT), with a P Flex device, or conventional breathing retraining (BR). Exercise performance was evaluated every(More)
A 59-yr-old man presented with mitral endocarditis and negative blood cultures. Antibodies to phase 2 and phase 1 antigens of Coxiella burneti were detected and a diagnosis of Q fever endocarditis was made. Five years earlier, this patient had been successfully treated by aortic valve replacement for a first episode of endocarditis with negative blood(More)
BACKGROUND Continuous positive airway pressure (CPAP) treatment improves the risk of cardiovascular events in patients suffering from severe sleep apnea-hypopnea syndrome (SAHS) but its effect on the link between delta power band that is related to deep sleep and the relative cardiac vagal component of heart rate variability, HF(nu) of HRV, is unknown.(More)
