Xavier Calvet, Jordi Bruix, Pere Ginés, Concepció Bru, Manel Sole, Ramón Vilana, Joan Rodés – 1 October 1990 – To investigate the prognostic factors in Western patients with hepatocellular carcinoma, 206 patients with confirmed diagnoses of hepatocellular carcinoma were studied in terms of survival. All patients were diagnosed between 1983 and 1987.
Ping‐Ing Lee, Mei‐Hwei Chang, Chin‐Yun Lee, Hong‐Yuan Hsu, Juei‐San Chen, Pei‐Jer Chen, Ding‐Shinn Chen – 1 October 1990 – During a follow‐up period of 3.2 ± 1.6 (1 to 8.6) yr, 1,087 serum specimens from 230 HBsAg carrier children were tested for hepatitis B virus markers.
Ulrich Gärtner, Tobias Goeser, Adolf Stiehl, Richard Raedsch, Allan W. Wolkoff – 1 October 1990 – In patients with cholestasis, levels of sulfated bile acids rise. Sulfate esters of chenodeoxycholic acid are the most abundant of these bile acid sulfates. These compounds are taken up by the liver and excreted into bile, although their plasma clearance and biliary excretion are reduced compared with that of unsulfated bile acids. It is not clear whether this is due to differences in intrinsic hepatic uptake or biliary excretion.

Marshall M. Kaplan – 1 October 1990 – Ten histological criteria were evaluated semiquantitatively in the liver biopsies of 60 patients with rheumatoid arthritis (RA) before initiation of methotrexate (MTX) and were compared with 40 biopsies taken during MTX treatment (mean cumulative dose 1,322 mg). Mesenchymal changes (Kupffer cell proliferation, portal tract infiltration) and parenchymal alterations (nuclear variability, ballooning, fatty infiltration) were very common without statistically significant difference between the 2 groups.

Bruce A. Runyon – 1 October 1990 – Spontaneous bacterial peritonitis is diagnosed when (a) the ascitic fluid culture is positive, (b) the ascitic fluid neutrophil count is ≥ 250 cells/mm3 and (c) there is no evident intraabdominal surgically treatable source for infection. Few details are available regarding the variant of ascitic fluid infection in which the culture grows bacteria (pure growth of a single type of organism), but the neutrophil count is <250 cells/mm3.
Wouter H. Lamers, Willem Been, Robert Charles, Antoon F. M. Moorman – 1 October 1990 – Urea cycle enzymes and glutamine synthetase are essential for NH3 detoxification and systemic pH homeostasis in mammals. Carbamoylphosphate synthetase, the first and flux‐determining enzyme of the cycle, is found only in a large periportal compartment, and glutamine synthetase is found only in a small, complementary pericentral compartment.
