To quantify the influence of continuous positive pressure ventilation (CPPV) on hepatic plasma flow (HPF) in 8 critically ill patients submitted to controlled ventilation, we measured simultaneously HPF by the indocyanine green dye (IGD) clearance and cardiac output (CO) by the thermodilution technique, while increasing PEEP from 0--20 cm H2O. CPPV induced(More)
In patients with acquired or congenital heart diseases, the systolic pulmonary artery pressure (PAPs) can be predicted using continuous-wave Doppler ultrasound (CWD) measurement of the peak velocity of a tricuspid regurgitation (TR) jet. The aim of this study was to determine whether CWD could be used to accurately estimate PAP in patients with chronic(More)
Pulsed Doppler echocardiography of the inferior vena cava is an accurate method for the diagnosis of tricuspid regurgitation and impaired right ventricular compliance, two features of pulmonary hypertension. The purpose of this study was to assess the value of Doppler echocardiography of the inferior vena cava for the detection of pulmonary arterial(More)
Objective: To investigate the effects of low-dose dopamine (Dop) on renal hemodynamics and function in patients with brain trauma receiving norepinephrine (NE). Design: Prospective clinical study. Setting: Surgical intensive care unit of a university hospital. Patients: 20 stable, non-septic, mechanically ventilated, sedated patients with brain trauma and(More)
The authors present a retrospective study of 169 cases of premature rupture of the membranes. The diagnosis was made before there was any marked flow of liquor and before labour had started. The authors show that the neonatal infection rate was 12.42%. They first defined their criteria for diagnosing neonatal infection and show what risks are involved(More)
BACKGROUND Lung cancer aetiology and clinical aspects have been mainly studied in men, although specific risk factors probably exist in women. Here we present the rationale, design and organization of the WELCA study (Women Epidemiology Lung CAncer) that has been launched to investigate lung cancer in women, focusing particularly on hormonal and(More)
The existence of chestnut pollinosis in Paris is not generally accepted in spite of the production of very large quantities of chestnut pollen in July. We carried out systematic skin-prick testing with chestnut pollen on 81 patients seen in the allergology department. The results were positive in 17 of the 47 patients presenting seasonal symptoms and in(More)
