To determine the cytokine release during normothermic cardiopulmonary bypass, we have measured plasmatic levels of tumor necrosis factor-alpha and interleukins-1 beta, 6, and 8 in 10 patients during the first 24 hours after the start of bypass. Arterial blood samples were collected at intervals before, during, and after bypass. Interleukin-1 beta was not(More)
Rats were treated with propylthiouracil (PTU) for 10-day periods beginning at different ages. Daily injections of L-thyroxine (T4) were administered concurrently with PTU to a group of rats which served as one control group. Peripheral auditory function was evaluated by the brainstem response audiometry (BSRA) technique performed at 12, 16, 25 and 120 days(More)
Cardiac valve replacement is a rare but not exceptional eventuality in patients with relapsing polychondritis. One case requiring aortic and mitral valve replacement and its follow up is described. From the review of the literature an additional twenty patients who required cardiac valve replacement are analyzed. The mean delay between the first onset of(More)
To evaluate the ability of ECG-gated spin-echo (SE)-MR imaging vs. cine-MR imaging to assess coarctation of the aorta, 11 patients aged 15-45 years, with known or suspected coarctation of the aorta, and five patients suspected of re-stenosis or postoperative false-aneurysms after coarctation repair were examined by multisection SE-MR imaging and(More)
Among 128 consecutive patients operated upon between 1972 and 1984 at the Marie-Lannelongue Surgical Centre for incomplete persistent atrioventricular canal, 102 could be followed up for periods ranging from 18 months to 11 years. Of the 23 patients lost sight of, 19 were foreigners. One patient died during the first postoperative month and two died during(More)
Respiration, as judged by gas exchange and pulmonary function, is improved in preterm infants kept in the prone rather than the supine position. The influence of position on the breathing pattern as documented by the pneumogram was studied in 14 stable preterm infants with recent clinical apnoea. Ten of the infants had oximetry and nasal flow studies(More)
PURPOSE To compare transesophageal echocardiography (TEE) and magnetic resonance (MR) imaging in the diagnosis of dissection of the thoracic aorta. MATERIALS AND METHODS Thirty-one consecutive patients with clinically suspected aortic dissection and 10 postoperative patients underwent transesophageal color Doppler echocardiography and MR imaging.
