[Liver changes in people of conscription age--"carriers" of hepatitis B and C viruses].

89 liver needle biopsies from young persons--HBV and HCV carriers--were studied histologically, immunohistochemically, morphometrically and electron microscopically. Groups with compensatory-adaptive and degenerative liver lesions, those with mild manifestations of a chronic virus infection, and those with chronic hepatitis of minimal and weak activity were identified. Latent chronic hepatitis is found in 68.5% of HBV and HCV carriers. Morphological picture of HCV infection is more pronounced as compared to that of HBV infection. The role of eosinophils in the development of hepatitis B and C forms lacking clinical symptoms is demonstrated.

[Experience in teaching microscopic diagnosis to beginning pathologists].

The following methods of microscopic diagnosis training are proposed: the analysis of microscopic slides using the microscope equipped with video camera visualizing images on the screen of telemonitor with a group of 2-4 physicians; situation tasks using histological slides from legal postmortems; discussion with trainees of their conclusions on current biopsies obtained by these trainees; situational tasks on the sets of biopsies of last years.

[The diagnosis of acute liver failure in the surgical clinic].

An analysis of 50 case histories of surgical patients who died from nonhepatic diseases has shown that acute hepatic insufficiency is often hyperdiagnosed. Possible causes of this hyperdiagnosis resulting from insufficient information and wrong interpretation of laboratory findings are discussed.
