摘要:

SummaryThe author presents and discusses the various factors involved in the modifications observed in coronary circulation. He stresses the importance of the enzymatic systems participating in cardiac metabolism and also of their inhibitors and activators. It is likely that the modifications in ionic equilibrium are responsible for the modifications of cardiac contraction.

摘要:

SummaryIn order to discuss by-pass indications for coronary syndroms, it is necessary to know perfectly well the anatomical lesions.Unfortunately, chances of success are not too good in this field, especially for the following reasons : the usual size of the stenosis, the small section of the corresponding arteries, the special risks due to the abnormal myocardium.Surgery can nevertheless be considered in certain cases, especially when medical treatment fails; the best indication being syphilitic angina pectoris.In far more common atherosclerosis, the theoretical indications for bypass would be : angina pectoris at exertion, lasting since more than six months, appearing in a young worker—a few cases of status anginosus, resisting to all coronary and extra-coronary treatments - perhaps even certain cases of incipient cardiac failure in young patients with coronary insufficiency.A good coronary arteriography should allow to select the few cases with enough localized anatomical lesions to permit good surgical compensation. One should prove by coronary arteriography that the permeability restored by surgery can usually be maintained, despite the small section of the coronary ramifications.

摘要:

SummaryThe author recalls the history of Fieschi operation and the experimental work done about it. He reports his own experience in using that technic and the results obtained with regard to the clinical condition of the patients and their E.C.G. tracing. When this operation seems insufficient, the author performs an epipericardio-epicardiopexy, which removes the avascular membrane of the pericardium and facilitates the appearance of anastomoses and the development of collateral coronary circulation.

摘要:

SummaryHypercalcemia with alkalosis may be encountered in other clinical conditions than milk-alkali syndrome.Three patients, one with parathyroid adenoma, the two others with metastatic malignancy, had very high blood level of calcium and alkalosis.In two cases, a previous treatment with sodium citrate or sodium bicarbonate may partly explain this shift in blood pH.Metabolic studies revealed the following facts:1)Renal function was seriously impaired in two patients, creatinine clearance technique disclosed slight reduction of the glomerular function in a third one.2)In two patients, urinary output of calcium was high.3)Hypokaliemia was observed twice, a normal potassium level in blood was demonstrated in the hypoparathyroid subject although a severe degree of uremia.4)Normal urinary potassium output was demonstrated in one of the hypokalicmic patient showing a disturbance in renal handling of potassium. This finding may be attributed to alkalosis or to hypercalcemia.5)Paradoxical aciduria was observed in two patients. Evidence for potas-sium depletion in these cases was lacking.6)Phosphoremia remained in the normal range in all patients. Low nor-mal values were observed in one patient with metastatic malignancy. Phos-phate clearance values were slightly increased in this case.

摘要:

SummaryA case of polyradiculoneuritis following chickenpox is related. So far only ten other cases have been described in the literature. Modern concepts concerning the etiology of the disease are briefly discussed.
