The pathology of noncirrhotic portal fibrosis: a review of 32 autopsy cases.

A wide spectrum of clinical and morphologic changes in 32 autopsy cases of noncirrhotic portal fibrosis have been described. The disease frequently occurs in younger patients with a long history of splenomegaly, usually with a history of hematemesis. Females are affected almost equally as often as males in contrast to cirrhosis. The patients tolerate the bleeding episodes well. Death is usually due to massive hemorrhage. The diagnosis is achieved through a process of exclusion. A critical analysis of hemodynamic data, a splenoportogram, liver function tests (particularly Bromsulphalein retention) and angiographic data is mandatory. Needle biopsy of the liver appears to have limited value in making the diagnosis. The gross anatomic findings vary from a nearly normal liver to gross nodularity, seen particularly on the posteroinferior surface. In some cases these nodules are seen to physically impede the portal blood flow and contribute to portal hypertension. Phlebosclerosis of the smaller radicles of the portal vein and irregular scarring are the outstanding morphologic features of the disease. These changes are usually associated with irregular dilatation of some of the larger intrahepatic branches of the portal vein as well as fibroelastosis with or without occluding or organizing thrombi in both intra- and extrahepatic branches of the portal vein. The changes in hepatic venous radicles are characterized by irregular sclerosis, which seems to contribute significantly toward postsinusoidal block in advanced cases. The probable mode of evolution is discussed.

Amebic peritonitis.

Fifteen cases with generalized amebic peritonitis have been described. Early surgical intervention combined with intensive resuscitation and specific chemotherapy has given good results. Mortality associated with colonic perforation may be reduced by performing staged procedures. Chances of survival may be improved through early diagnosis by suspecting an amebic cause in cases of generalized peritonitis in endemic areas.

Hepatitis B virus infection in northern India. Prevalence, subtypes, and seasonal variation.

Previous reports from India have been limited to the incidences of hepatitis B antigen (HB Ag) in health and disease. This paper reports on a study undertaken over the last two years to determine the incidence of hepatitis B virus infection, the serotypes prevalent among apparently healthy individuals and patients with liver diseases, and the seasonal incidence of sporadic acute hepatitis in this geographic area. The incidences of infection in health and disease show an endemic pattern. The Y subtype predominates among healthy carriers and patients with chronic liver diseases, whereas the D subtype predominates in patients with acute hepatitis. The similarity of subtypes of HB Ag among the majority of healthy carriers and patients with chronic liver diseases suggests that the majority of asymptomatic carriers (subclinically infected) would develop chronic liver disease. The proportion of HB Ag-positive cases of acute hepatitis was significantly higher during the two summer seasons than during the two winter seasons; this could be due to more frequent transmission of the virus by the faecal/urinary-oral route and its activation during the summer months, especially in areas with poor hygienic conditions. The urinary/faecal excretion of virus could thus maintain the natural transmission of the virus in such an environment.
