[Markers of type B viral hepatitis].

The discovery of Australian antigen (HBsAg) has led to an increasing deal of knowledges about the virus of type B hepatitis (HBV); several markers of HBV have been detected and are becoming disposable for clinical and epidemiological purposes. The HBsAg is carried by 3 types of particulate structures discovered by electron microscopy as small spherical particles having diameter around 22 nm, long filaments and spherical particles having an overall diameter of the 42 nm (Dane-particle) with an electron-dense core. Dane-particle core contains circular double-stranded DNA molecules and an enzyme, the DNA polymerase. At present, Dane-particle is thought to represent the HBV, having properties consistent with those of a complete virus. Four antigen/antibody systems related to viral type B hepatitis have been discovered; they have been designated with the following nomenclature: HBsAg/anti-HBs, HBcAg/anti-HBc, HBeAg/anti-HBe, epilon antigen/anti epilson. The availability of the HBV markers for clinical purposes will permit a better understanding of the sequence of the biological reactions as well as of the clinical and epidemiological features concerning this viral infection: incubation period, acute disease, resolution, chronic carrier state, actively or passively immunized subject, persistent or subsided infectivity, prognosis.

[Isolated hepatosplenic tuberculosis: 1 case].

A 27-year-old woman presented with high spiking fevers, progressive malaise, weight loss, and marked hepatosplenomegaly. The clinical picture and laboratory findings (including hepatic scintiscan, coeliac arteriography and abdominal lymphangiography) prompted surgical exploration of hypochondriac organs. On laparotomy, both liver and spleen surface exhibited extensive inflammatory lesions. Histopathologic investigations on hepatic tissue showed microscopic caseating granulomata. Specific stains and cultures for mycobacterium, fungi etc. were negative in tissue preparations. Antituberculous and steroid therapy elicited a rapid response. Follow-up observations indicated the resolution of specific hepatic lesions.

[Type B viral hepatitis. Recent findings].

The discovery of hepatitis B surface antigen by Blumberg in 1965 offered a specific marker that could readily be employed in the clinical, epidemiological and experimental investigation of type B viral hepatitis. It has since been followed by the continuous gathering of further knowledge concerning this disease. The morphology and immunological and biochemical features of virus B, the epidemiology and prevention of hepatitis B, and marker determination techniques are examined in an overview of the present situation.

Metastatic involvement of the pancreas from renal cell carcinoma treated by surgery.

A solitary late recurrence of renal cell carcinoma is very unusual. A case of triple pancreatic metastases of renal carcinoma is presented in a male patient who 9 years previously had undergone left radical nephrectomy. Although there are no specific signs, arteriography, computed tomography and intraoperative ultrasonography can give additional information to detect this rare localization. Surgical resection, when possible, is the most useful treatment for this metastatic lesion.
