[Bilateral adrenal metastases with the clinical manifestations of hypocorticism in rectal cancer]. / Dvustranni nadbubrechni metastazi s klinichni proiavi na khipokortitsizum pri rak na rektuma.

Metastases in the suprarenal glands are being found in patients with neoplasms but symptomatic hypocorticism is described in single cases only. Computed tomography allows the diagnosis of suprarenal metastases causing hypocorticism while the patients are still alive. A case of a man, 40 years of age, with rectal carcinoma and clinically manifested hypocorticism due to bilateral suprarenal metastases is presented.

[A case of tuberculous myocarditis and rupture of a dissecting aortic aneurysm and of the left coronary artery of the heart during surgery for an aortic heart defect]. / Vurkhu edin sluchai s tuberkulozen miokardit i ruptura na disetsirashta anevrizma na aortata i liavata venechna arteriia na surtseto po vreme na operatsiia na aorten porok na surtseto.

A rare case of tuberculous myocarditis, miliary type, in hematogenic-disseminated tuberculosis of lungs and liver is reported. Some morphological characteristics of tubercules in myocardium require a broad differential diagnosis with idiopathic granulomatous myocarditis, sarcoidosis, lues and brucellosis. Tuberculosis was in combination with isolated heart defect-- insufficiancy of aortic valve, hypertonic disease, atherosclerosis, dissecting aneurysm of ascending aorta and left coronary artery of the heart, complicated by a rupture during the cardiac operation.

[Microcirculation of the aorta and coronary arteries in patients who died of myocardial infarct and generalized arteriosclerosis]. / Vurkhu mikrotsirkulatsiiata na aortata i venechnite arterii na surtseto pri pochinali s infakt na miokarda i generalizirana ateroskleroza.

The authors studied the microcirculation changes in ascending aorta and left coronary artery of the heart in 25 deceased with myocardial infarction, aged from 52 to 80, with two control groups: 20 cases with complicated atherosclerosis, aged from 54 to 80, and 4 cases--without atherosclerosis, aged 30-45. Histological and histochemical investigation methods were used. The authors found grave changes in vasa vasorum of aorta and coronary artery with the formation of arteries of "closing" type, hyperplasia of the muscular layer of the arterial and venous vessels anf fibrosis of their wall in the deceased with healed myocardial infarction and chronic coronary and cardiac insufficiency. Acute disturbance of blood microcirculation was observed in recent myocardial infarction, analogical to that in case of shock. Necrosis of the type of anemic infarctions and stratification of the wall with hemorrhages and fresh thrombosis were found in the media of aorta and coronary artery in myocardial infarction and atherosclerosis. Both necrosis and stratification are associated with the manifested endothelial proliferation, recent and organized thrombus in the small vasa vasorum and grave structural changes in the supplying vessels of aorta and coronary arteries.
