[Evaluation of the analgesic activity of a soluble precursor of aspirin in orthopedic surgery].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
We carried out a randomized double-blind trial to evaluate the analgesic effect, rapidity of action and tolerance of calcium carbasalate relative to a placebo, given in a single dose of 1 gr. aspirin equivalent immediately after an orthopedic surgical procedure. Autoevaluation by the patient using a visual scale and overall evaluation of analgesic ...
[Computed x-ray tomography in the detection of venous extension in renal cancer].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
With reference to eleven cases of renal cancer with involvement of the inferior vena cava, CT semeiology of this venous complication is detailed. Furthermore, the authors suggest that the images are capable of a pathological interpretation which may indicate whether the obstruction is caused by the tumor or a thrombus. Lastly, the value and limitat...
[Immunopathology in 35 cases of chronic urticaria].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Although urticaria is usually held to be a type 1 hypersensitivity reaction, it may also be the cutaneous manifestation of vasculitis mediated by immune complexes. In this study of 35 patients with chronic urticaria, the authors attempted to specify the prevalence of vasculitis and its possible correlations with particular clinical and/or immunolog...
[Leukotrienes].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Leukotrienes are released in inflammatory and immediate hypersensitivity reactions. Leukotrienes are novel metabolites of arachidonic acid produced by the lungs and leucocytes. Their formation is catalyzed by a specific 5-lipoxygenase. The key compound of this pathway is leukotriene A4 which is transformed either into leukotriene B4 by enzymatic hy...
[Polypeptides and antagonists].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Polypeptides are endogenous agents, involved in the regulation of many physiologic functions and the pathogenesis of several diseases. Polypeptide antagonists form a group of new chemical entities which may provide valid therapeutic agents. Some polypeptides (angiotensin, kinins) are released through the action of proteolytic enzymes (renin, kallik...
[Treatment of advanced ovarian cancer].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Forty patients with stage III or IV ovarian epithelial carcinoma, mean age 61 +/- 12 years, were treated either with cyclophosphamide-methotrexate-5-FU or with cisplatinum-adriamycin-5-FU-hexamethylmelamine. Median survival from initial surgery was 16 months, 18 months in stage III and 2 months in stage IV disease. 15 patients over 70 years had a m...
[Castleman's tumor with thoracic localization. Apropos of a case].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Castleman tumor usually presents as a mediastinal tumor which is never accurately diagnosed before surgery. Pathological findings and postoperative course establish the benign nature of this tumor. However, plasmocytic forms with prominent hematologic manifestations may be difficult to distinguish from a malignant lymphoma or thymoma. Differential ...
[Determination of urinary xanthurenic acid after oral loading of L-tryptophan in 88 cases of photodermatosis].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
Disturbances in the kynurenine pathway are present in pellagra and pellagroid syndromes. In 88 photodermatoses, the authors found increased urinary excretion of xanthurenic acid after oral load of tryptophan in a number of light-induced eruptions, i.e. benign summer photodermatosis (40%), polymorphous light eruptions (37%), and persistent light rea...
[Evaluation of vascular surgery with digital subtraction angiography. A study of 127 patients].
Published in La semaine des hôpitaux : organe fondé par l'Association d'enseignement médical des hôpitaux de Paris
We have performed digital subtraction angiography (DSA) on 127 patients treated by vascular surgery. This technique was easily and safely performed in outpatients, without any complication. Our experience indicates that DSA is accurate for post operative evaluation in 96% of cases. In digestive arterial surgery, some examinations (3.3%) are insuffi...
