Amebic perforation of the colon.

Acute necrotising colitis and perforation of the colon due to amebic infection is usually fatal. Only three patients in the present series of nine survived surgery. Preoperative diagnosis was not possible and because of an extremely friable, blotting paper like colon, this condition was only suspected at laparotomy. Examination of ulcer scrapings for the presence of Entamoeba histolytica or histopathology is confirmatory. Resection anastomosis is mandatory as less extensive local procedures or bypass surgery are not always feasible.

Non-surgery related aspergillus native valvular endocarditis: report of two cases.

Two unusual cases of aspergillus valvular endocarditis without any history of cardiovascular surgery found at autopsy are reported. As there is a chance of dissemination, early diagnosis is important. Clinical awareness can lead to early recognition and effective treatment of this potentially lethal condition.

Intracardiac autonomic ganglion cells in leprosy and dilated cardiomyopathy.

Disturbances in cardiac autonomic functions are known to occur in patients of lepromatous leprosy and dilated cardiomyopathy. We have analyzed the number of cardiac autonomic ganglion cells in patients of lepromatous leprosy (2 cases), dilated cardiomyopathy (2 cases) and compared with those of control subjects (2 cases). The average number of ganglion cells in cases of dilated cardiomyopathy (1164) and leprosy (1138) did not show any significant deviation from the average neuronal number of control subjects (1352).

Pattern of hypertrophy of left ventricle--a histometric analysis of eighteen cases.

The pattern of myocardial hypertrophy in different sites of the left ventricular wall was morphometrically analysed in aortic stenosis (6 cases), hypertensive hypertrophy (5 cases), mitral incompetence (4 cases), and dilated cardiomyopathy (3 cases). The diameter of individual circumferentially oriented mid wall (or middle) fibre was significantly greater than those of subepicardial and subendocardial zones. Thus, hypertrophy does not affect the entire left ventricular myocardium uniformly. It seems to vary according to the spatial configuration of the fibrosis in relation to the cavity.

Morphologic and arteriographic changes in the pulmonary vasculature in children with congenital heart disease.

This study was undertaken to determine the morphologic changes occurring in the pulmonary vasculature in congenital heart disease. Autopsy was performed in twenty cases of congenital heart disease ranging in age from newborn (full term) to 14 years. Postmortem arteriography was performed in most of them followed by histomorphometry. It was found that medial hypertrophy of the muscular pulmonary arteries was the most consistent change and the smallest muscular arteries were the most severely affected. The lesions were focal and randomly distributed. Hence, morphologic observations on open lung biopsies may not be accurate.
