Application of negative pressure at the mouth during tidal expiration (NEP) provides a simple, rapid, noninvasive method for detecting expiratory flow limitation during spontaneous breathing. Patients in whom NEP elicits an increase in flow throughout expiration are not flow-limited (FL). In contrast, patients in whom application of NEP does not elicit an(More)
Expiratory flow limitation and dyspnea during resting breathing are common in patients with severe chronic obstructive pulmonary disease (COPD). Although single lung transplantation (SLT) is used to treat end-stage COPD, its effects on flow limitation and dyspnea are not well established. We assessed expiratory flow-limitation and dyspnea in 13 COPD(More)
Self-inflicted acute drug overdose in suicidal elderly patients appears to be a growing challenge to public health. To the best of our knowledge, little has been published on this topic. Thus we undertook a retrospective study, from January 1969 to October 1989, in a medical ICU. Ninety-two suicidal, elderly patients (54 women, 38 men) with a mean age of 77(More)
CLINICAL SETTING Purulent collections in the pleural cavity usually occur as complications of pneumonia in immunodeficient or socially underprivileged patients. PUNCTURE ASPIRATION The key to diagnosis, pleural aspiration is indicated in case of sufficiently abundant collections, especially in patients with fever. Exploratory puncture is a therapeutic(More)
