[Retrospective analysis of the incidence of midline supratentorial neoplasms in children and young patients: craniopharyngiomas, hypophyseal and pineal neoplasms].

The authors analyzed, in a retrospective study made at the Pathology Department of the Medical School of the University of São Paulo, 1632 cases of intracranial neoplasms in a period of 50 years (1931-1981). The investigation concentrated on 592 cases (36.2%) of patients with age ranging from 0 to 20 years. The overall number of craniopharyngiomas in this group was 21 (3.5%); 8 cases (1.35%) of hypophyseal neoplasms, and 4 cases (6%) of pineal neoplasms. Neoplastic infiltration of the hypophysis and pineal was present in 24 cases (4.0%). No metastases were observed. The description and importance of these findings, and their correlation with data from other authors are presented.

[Progressive systemic sclerosis, B-cell malignant lymphoma of the ileum and thyroid adenocarcinoma].

A patient with progressive systemic sclerosis with rapid evolution to death is presented. The post-morten examination revealed besides the typical changes of the progressive systemic sclerosis in the skin, kidneys, heart and blood vessels a B-cell ileal malignant lymphoma with generalized metastases, and an adenocarcinoma of the thyroid gland. A possible mechanism involved in the association of these diseases might be the action of the oncogenes modifying the cellular hormostasis and the immunological tolerance.

Later complications on diabetic patients: nephropathies in necropsy material.

The purpose of the present study was to analyze in detail the kidney lesions of diabetic patients. Revision of the histopathologic aspects of this nephropathy was performed, seeking to approach the pathophysiology of its formation. In 200 consecutive necropsies of cadavers of diabetic patients examined at the Pathology Department of the Medical School of the São Paulo University, some degree of nephropathy was found in 158 cases. The slides from paraffin sections of these cases were reviewed according to a morphologic protocol previously established. Diffuse, nodular and mixed glomerulosclerosis were encountered in 42.2%, 21.5% and 5.7% respectively. Subcapsular drop and exudative lesion appeared in 12.7% and 15.2% of the cases. We also encountered arteriosclerosis in 81.6%, arteriolosclerosis in 88.6%, necrotizing papillitis in 11.4% and acute and chronic pyelonephritis in 23.4% and 20.9% respectively. We concluded that glomerular and vascular hyalin alterations were the most frequent findings in diabetic patients.

Thyroid papillary carcinoma lipomatous type: report of two cases.

The authors present two cases of a new variant of papillary carcinoma of the thyroid gland with an unusual lipomatous component. The first case occurred in a 50-year-old woman: the thyroid gland showed lipomatous foci in the stroma of the papillary carcinoma. The second case occurred in a 38-year-old man with the same lipomatous component appearing in small foci. In both cases, the lipomatous tissue was found within the stroma. As far as we known, there are only tree other reports of this type of thyroid gland carcinoma in the literature.

Study in necropsy material of "cause-specific mortality" in diabetics, in São Paulo-Brasil.

Specific causes of death in diabetic patients was studied in retrospective work from necropsies performed at the Medicine School of the University of São Paulo from 1931 until 1989. From 145,043 necropsies, 813 indexed cases were found: 449 females (55.2%) and 364 males (44.8%). The race ratio of patients was: 584 (71.8%) white, 208 (25.6%) negro and 21 (2.6%) asiatic. The predominant age of death incidence was between the fifth and sixth decades. The main causes reported were infections (42.68%), coma (12.79%), neurologic involvement (11.56%) and cardiac diseases (11.07%); indeterminate causes of death were related in 7.4% of cases. Our results differ from the others of literature mainly in two points: the high prevalence of infectious diseases and the proportional low incidence of cardiopathies. We concluded that, in our casuistic, infectious diseases in diabetic patients represent an important cause of death establishing important clinical parameters for their care.
