Acute superior vena cava and right atrial tamponade in an infant after open heart surgery.

Early postoperative localized cardiac tamponade occurred in a 4-month old infant after ventricular septal defect repair. The clinical findings were as for acute superior vena cava syndrome. The diagnosis was accurately made using echocardiography and measurement of the superior vena cava and right atrial pressure. Surgical revision was necessary to remove a large clot from the superior vena cava-right atrium junction.

Unusual localisation of a ventricular septal defect following blunt chest trauma.

A 64 year old man presented with a traumatic ventricular septal defect following blunt chest trauma 40 years before. Echocardiography and left ventriculography were helpful in locating the unusual septal defect, which was subpulmonary. The shunt was small, but the anomalous chronic overload led to right ventricular failure. The surgical correction was thus too late to improve right ventricular function.

[Monotherapy, empirical and targetted, with imipenem-cilastatin in sepsis of bacterial origin].

The authors describe an open study in 22 patients with febrile conditions of unknown origin who were treated with imipenem-cilastatin while waiting for routine laboratory and culture tests. These were done immediately at the patients' entry into hospital, after which imipenem-cilastatin treatment was started immediately, and was subsequently confirmed by the isolates and culture tests. The drug was found to be active and to eradicate the responsible organism in all cases. In addition, it was found to be easy to handle and not to give rise to side-effects or changes in laboratory tests.

Hypercoagulable state in hypercholesterolemic subjects assessed by platelet-dependent thrombin generation: in vitro effect of cerivastatin.

BACKGROUND: Hypercholesterolemia is an important risk factor to develop acute thrombotic complications of atherosclerosis like to myocardial infarction and ischemic stroke. Platelets and coagulation factors are strictly involved in the genesis of such thrombotic events and their hyperactivity in hypercholesterolemic patients has been previously reported. Moreover some cholesterol-lowering molecules (statins) seem to be able of reducing platelet activity. METHODS: We performed platelet-dependent thrombin generation (colorimetric method) to assess the coagulative potential of 40 caucasian hypercholesterolemic subjects with respect to normal controls and to the grade of hypercholesterolemia. Moreover we observed the effect of platelets from hypercholesterolemics on thrombin generation in plasma from normal subjects. The effect of Cerivastatin on thrombin generation was evaluated too. RESULTS: Our data show an increased thrombin generation both in mild and high hypercholesterolemic subjects with respect to controls (424.6+/-30.5 vs. 197.1+/-27.4 mIU/ml). No significant difference in the amount of thrombin generation was found between mild and high hypercholesterolemics (399.6+/-20.7 vs. 440.2+/-21.4 mIU/ml). Platelets directly influence thrombin generation and they present an intrinsic hyperactivity that can be modulated by Cerivastatin (223.6+/-24.8 vs. 424.6+/-30.5 mIU/ml). CONCLUSIONS: Mild hypercholesterolemia is associated with an increased thrombinic potential that may be considered an added risk factor to develop thrombotic events. Platelets directly influences this hypercoagulative state and Cerivastatin is able to reduce thrombin generation by way of a direct interaction with platelets.
