[Changes in human biliary vesicle sizes in pathological states].

Changes in the sizes of aggregates of bile vesicles at various nucleation factors were studied by the method of dynamic spectroscopy. It was found that the sizes of bile vesicles in chronic cholecystitis vary from 90 to 200 nm. It was shown that the presence of a large fraction of bile vesicles characterized by a higher cholesterol concentration can serve as a criterion of acuteness of cholecystitis and the intensity of lithogenesis.

Finno-Ugrians and homicide.

The percentage of Finno-Ugrians in the population in 30 European nations in 1990 was not associated with the national homicide rates.

[Clinical-pathologoanatomic analysis of post-operative thromboembolism of pulmonary artery].

Autopsy and clinical data were analysed for 803 surgical patients whose death was due to pulmonary artery thromboembolism (PAT). PAT was diagnosed intravitally in 32% of the deceased. 87% of the patients with PAT symptoms died within 2 hours.

Characteristics of follicular tumors and nonneoplastic thyroid lesions in children and adolescents exposed to radiation as a result of the Chernobyl disaster.

Background: In addition to the previously reported increase in incidence of thyroid carcinomas in Belarussian children after the Chernobyl disaster in April, 1986, benign thyroid lesions were also found to be increased in the exposed population.

Methods: A total of 60 follicular neoplasms and benign nonneoplastic thyroid lesions arising after the Chernobyl disaster in children and adolescents of 7 to 18 years of age were studied.

Results: The primary diagnoses in this series were follicular carcinoma in 1 (2%) case, follicular adenoma in 9 (15%), cystic adenomatoid nodule with papillae in 18 (30%), multinodular goiter in 18 (30%), diffuse hyperplasia in 2 (3%), diffuse hyperplasia with atypia and nodularity in 5 (8%), lymphocytic thyroiditis in 6 (10%), and thyroid cyst in 1 patient (2%).

Pediatric thyroid cancer after the Chernobyl disaster. Pathomorphologic study of 84 cases (1991-1992) from the Republic of Belarus.

Background: During the initial period after the Chernobyl accident, large amounts of radioactive iodine were released in fallout, resulting in serious exposure to the thyroid gland in the residents of areas around the nuclear power station. Beginning in 1990, a definite increase in the incidence of thyroid cancer was noted in children of the Republic of Belarus.

Methods: Morphologic and clinical features of 84 cases of post-Chernobyl thyroid carcinoma in Belarussian children from 5 to 14 years of age are reported.
