[The behavior of various muscle enzymes in hypothyroidism].

The behaviour in hypothyroidism of certain muscular enzymes (CK, TOE, LDH, AST) was studied. A significant increase in these enzymes occurs in basal conditions and is gradually normalised by substitution therapy. This response might serve to distinguish hypothyroidism from other conditions causing an increase in muscular enzyme levels.

[Cardiovascular manifestations of dermatopolymyositis].

The cardiovascular symptoms of six patients suffering from polymyositis were considered with reference to Pearson's classification. Transmural ischaemia type ventricular repolarisation anomalies were noted in two patients while clinica signis of cardiopathy were not present. A progressive disturbance in intraventricular condition was noted in one case.

[Renal angiomyolipoma. Analysis of a clinical case in the light of current diagnostic possibilities].

A clinical case of renal angiomyolipoma is examined. Until a few years ago diagnosis of this condition was almost exclusively intraoperative or during autopsy. Today, the introduction of new diagnostic techniques like echotomography and CT permit the identification of the lesion and its differentiation from other spreading renal processes.

[Carcinoid cardiopathy].

A series of 5 males and 2 females aged 23-73 yr with carcinoid cardiopathy is presented, all of them with clinical and instrumental signs of liver metastasis. The main clinical signs were dyspnoea and asthenia rendered ingravescent by effort, and, in the later stage, a frank picture of congestive cardiac decompensation. All subjected presented stethoscopic evidence of tricuspid valvulopathy, combined with pulmonary stenosis in 2 cases.
