Management of congenital choledochal cyst with intrahepatic involvement.

The clinical features and surgical treatment of 75 patients with choledochal cysts with intrahepatic involvement (Type IV-A) were evaluated. Seventeen were in this series and 58 were reviewed from the literature. It was of interest that the incidence of Type IV-A choledochal cysts was nearly 30%, considerably higher than had been previously assumed. This type is commonly found in older children and young adults. Abdominal pain and fever indicative of biliary tract infection are more frequent seen than in patients with Type I, and a mass is not commonly palpable. Surgical treatment of Type IV-A must achieve bile drainage from the intrahepatic cysts as well as from the choledochal cyst. For this reason, as well as the prevention of later development of cancer in the wall of the cyst, hepaticoenterostomy at the porta hepatis with partial resection of the wall of the intrahepatic cyst (or partial hepatectomy if possible) combined with excision of the intrahepatic cyst is recommended as the procedure of choice for type IV-A cysts.

Bilateral intracerebellar calcification associated with cerebellar hematoma. Case report.

A case of bilateral intracerebellar calcificaiton associated with cerebellar hematoma on the left side is reported. Clinical and microscopic examination failed to clarify the causes of calcification and hematoma. It is postulated that hemorrhage occurred from time to time through the fragile calcified vessel walls, since some portions of the organized hematoma were composed of massive erythrocytes.

Congenital bile duct cysts: Classification, operative procedures, and review of thirty-seven cases including cancer arising from choledochal cyst.

Congenital bile duct cysts are observed in any part of the bile duct from the liver to the duodenum. Reports of cases of cancer arising from it are increasing. Excision of the choledochal cyst seems to be the treatment of choice and partial resection of the intrahepatic cyst followed by intrahepatic cystoenterostomy at the porta hepatis is necessary for type IV-A cysts.

The fine structural localization of S-100 protein in rodent cerebellum.

This report describes the first fine structural locations of S-100 protein in the hamster cerebellum. Innovations in tissue fixation as well as tracer preparation enable localization of S-100 protein to several critical cellular and subcellular sites. Certain neuronal elements, Purkinje cells, contain S-100 protein in both cytoplasm and nucleus. Specific membrane structures including plasma membranes and the nuclear membranes of Purkinje cells are strikingly positive. Localization of S-100 protein to the pericapillary astrocytic endfeet as well as regions of the synapse are of particular biological interest. The clear nuclear localization of the molecule suggests a role in the genetic expression of the developing mammalian brain.

Immunocytochemical localization of simian virus 40 T antigen with peroxidase-labeled antibody fragments.

T antigen was localized in simian virus 40 lytically infected and transformed cells by Fab' antibody conjugates at the ultrastructural level. This virus-specific protein appeared in the cytoplasm of permissive cells as early as 3 h after infection. At later time intervals, the T antigen was localized in both the cytoplasm and nucleus and finally (24 h) in the nucleus. These results suggest a synthesis of T antigen on cytoplasmic ribosomes, with subsequent transfer to the nucleus.
