We have previously described a few peculiar myocardial abnormalities occurring in AIDS patients. In this report we have extended out observations on twenty-eight additional cases where the presence of perivessel fibrosclerosis and sclerosis mostly of intramural arteries, as well focal myocytolysis were confirmed at the autopsy.
More than 50% of AIDS patients show adrenal compromise. The major pathological findings include inflammatory changes of both the cortical and medullary portion with necrosis and haemorrhage. The principal determinant of these abnormalities appears to be CMV infection. We also report the occurrence of focal or subtotal hypophyseal necrosis in the setting of AIDS. These alterations of endocrine glands may deserve attention in the management of the patients.

The formation of multiple aneurysms in the midportion of Dacron grafts has been reported only twice in the surgical literature. In the present case, three aneurysmal dilatations developed 6 years following an orto-femoral Dacron graft implantation. Multiple structural defects in the Dacron prosthesis appear to be the most likely cause of the graft failure.

In order to investigate the morphological and functional changes produced in the colonic mucosa after prolonged exposure to gastric juices, 24 colonic patches were implanted on the gastric body and the gastric antrum. The specimens were removed, two, four or six months after surgery, and several morpho-functional changes were observed. These included a gastric-like transformation of the superficial epithelial cells, the presence, exclusively in the colonic patches implanted in the gastric body, of cells with large osmiophilic cytoplasmic granules and a progressive increase in sialomucin secretion with an almost complete disappearance of sulfomucins.
