To identify patients at risk of cardiac expansion during hospital stay for a first acute myocardial infarction (AMI), 41 patients underwent right-sided cardiac catheterization soon after admission and serial 2-dimensional echocardiography on days 1, 3 or 4 and between days 7 and 10. Infarct expansion was recognized by echocardiography in 11 patients (27%), most often on the second recording (day 3 or 4). Age, sex, time from onset of pain to catheterization, peak levels of creatine kinase and creatine kinase-MB isoenzyme, heart rate, mean pulmonary artery wedge pressure and left ventricular stroke work index were similar in the 2 groups. Patients in whom infarct expansion developed had a higher incidence of previous systemic hypertension (73% vs 27%, p less than 0.01) and anterior AMI (91% vs 30%, p less than 0.001) and a higher mortality rate at 1 year (73 vs 7%, p less than 0.001) than those who did not. They also had higher systolic (139 +/- 24 vs 126 +/- 18 mm Hg, p less than 0.05) and diastolic (91 +/- 14 vs 75 +/- 13 mm Hg, p less than 0.001) arterial pressures, lower stroke volume index (31 +/- 10 vs 40 +/- 10 ml/m2, p less than 0.01) and much higher systemic vascular resistance (SVR) values (1,713 +/- 380 vs 1,253 +/- 264 dynes s cm-5, p less than 0.0001). In the subgroups of patients with anterior AMI, differences were significant for diastolic arterial pressure, stroke volume index, SVR and mortality.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

The effects of saline (control, group C) and metrenperone (treated, group M) on systemic and pulmonary hemodynamics were determined in conscious 7- to 15-day-old calves after they were intratracheally inoculated with Pasteurella haemolytica. Metrenperone, a specific serotonin (5-hydroxytryptamine) receptor antagonist, was injected intramuscularly (100 micrograms.kg-1) 2 h after the calves were inoculated. Central venous, pulmonary arterial and capillary wedge, and systemic arterial pressures were measured, using fluid-filled catheters. Cardiac output was measured by the thermodilution technique. Heart rate, stroke volume, and pulmonary and systemic vascular resistances were calculated. The parameters were measured hourly from the 1st to the 10th h after inoculation. In group C, cardiovascular response to P. haemolytica inoculation was marked and typically consisted of two systemic hypotensive phases and two pulmonary hypertensive phases. The first phase occurred by the 2nd h post inoculation and was induced by a transient bradycardia and a systemic vasodilation, leading to profound hypotension and reduced venous return. Cardiac performance then transiently recovered, but systemic hypotension persisted. The second hypotensive hypodynamic phase occurred by the 7th h after inoculation, and was associated with a decline in stroke volume, an increase in heart rate, and pulmonary hypertension and vasoconstriction. In group M, the early response to P. haemolytica exposure was similar to that in controls, indicating that, as in sheep, 5-hydroxytryptamine does not contribute to the early hypodynamic response to endotoxemia. In contrast, metrenperone completely abolished late increases in pulmonary arterial pressure and pulmonary vascular resistance, suggesting that 5-hydroxytryptamine contributes to the late pulmonary vasoconstriction. Metrenperone treatment also allowed better restoration of heart rate, and hence, cardiac output was maintained. In conclusion, 5-hydroxytryptamine might have a role in mediating pasteurellic endotoxin induced changes in pulmonary hemodynamics through its type-2 receptors. [less ▲]

Le dosage de l'hémoglobine glyquée est utilisé en pratique quotidienne pour le suivi à long terme de l'équilibre glycémique chez les patients atteints de diabète sucré. De nombreuses techniques ont été décrites depuis une vingtaine d'années, fondées sur différents principes, et dosant différentes formes glyquées de l'hémoglobine. Cela explique que, bien que ce test très informatif soit utilisé au quotidien par les diabétologues, il existe encore une grande disparité des résultats d'un laboratoire à l'autre, rendant leur comparaison impossible.

New linear analogs of surfactin have been synthesized. Their physico-chemical parameters were determined. The results indicate that these linear products show surface activities although they are lowered compared to those of cyclic compounds. The hemolytic activities have also been assayed. In contrast with cyclic surfactins, no significant hemolysis occurs for the linear products in the range of concentrations tested. Moreover, a protective effect against Triton X-100 induced hemolysis has been highlighted for linear surfactins. The concentration at which this protective effect happens is correlated directly to the CMC, and inversely to the acyl chain length of the product. In a hypotonic medium, analogs having a long acyl chain tend to increase the hemolysis, meanwhile the product with the shortest chain tends to decrease it. [less ▲]

RÉ SUMÉ : Le syndrome hémolytique urémique (SHU ) est une affection assez rare chez l’adulte, mais de pronostic réservé. Il traduit une microangiopathie thrombotique essentiellement rénale. Nous rapportons l’histoire d’un jeune patient dont la présentation et l’exploration cliniques rendent le diagnostic de SHU probable. La présentation quelque peu atypique offre non seulement l’occasion de discuter des différents éléments qui plaident en faveur du diagnostic selon les hypothèses physiopathologiques les plus récentes, mais aussi de redéfinir les recommandations de la prise en charge en urgence de cette affection sévère.
