Harold O. Conn – 1 June 1989 – We conducted a prospective study of 321 patients with cirrhosis of the liver and esophageal varices with no history of bleeding to see whether a comprehensive analysis of their clinical features and of the endoscopic appearances of their varices could help to identify those at highest risk for bleeding. Varices were classified endoscopically as suggested by the Japanese Research Society for Portal Hypertension. Patients were followed for 1 to 38 months (median, 23), during which 85 patients (26.5 percent) bled.

Andrew K. Burroughs, Guerrino Mezzanotte, Andrew Phillips, P. Aiden McCormick, Neil McIntyre – 1 June 1989 – The importance of variable time of entry for analysis of survival following variceal bleeding has recently been disputed. In a study of 194 cirrhotic patients with bleeding esophageal varices in whom 2‐day mortality was 3%, statistically significant differences in both survival and rebleeding rates were obtained by shifting the starting point for analysis of survival by 2 weeks following admission to hospital or by 5 days for the analysis of rebleeding.

Stefano Gaiani, Luigi Bolondi, Silvia Li Bassi, Vittorio Santi, Gianni Zironi, Luigi Barbara – 1 June 1989 – The effect of a standard Italian meal on portal hemodynamics was evaluated in 12 normal subjects, in 11 patients with chronic active hepatitis and in 11 patients with liver cirrhosis using duplex Doppler ultrasound, which allows a noninvasive assessment of portal blood flow.

Brian J. McMahon – 1 June 1989 – To combat hepatitis B virus (HBV) infection in Taiwan, a mass immunoprophylaxis program was launched on July 1, 1984, aiming first at prevention of chronic HBV carriage from perinatal mother‐to‐infant infection. In the first 15‐month period, 352721 (78%) of 450585 pregnant women were screened for hepatitis B surface antigen (HBsAg); HBsAg was present in 62359 (18%), with 50% of them categorized as highly infectious.

Raymond S. Koff – 1 June 1989 – A survey of 434 oral surgeons was conducted to examine risk factors for hepatitis B virus (HBV) infection. Overall, 112 (26%) of the participants demonstrated serologic evidence of past or current infection with HBV. Seropositivity was significantly associated with age, number of years in practice, and year of graduation from dental school but not with other variables examined, such as the number of patients seen annually or the number of patients seen who were at high risk of HBV infection.

David Kravetz, Jaime Bosch, Maite Arderiu, M. Pilar Pizcueta, Juan Rodés – 1 June 1989 – The present study investigated whether, in rats with portal hypertension due to cirrhosis of the liver induced by carbon tetrachloride, blood volume restitution following a hemorrhage produces an increase of portal pressure beyond control values, as observed in rats with prehepatic portal hypertension.

Masao Arai, Shigeo Nakano, Fumio Okuno, Yoshiaki Hirano, Kazufumi Sujita, Toshiji Kobayashi, Hiromasa Ishii, Masaharu Tsuchiya – 1 June 1989 – The present experiments were designed to study the effect of chronic ethanol consumption on endotoxin toxicity. The intravenous injection of endotoxin produced a more pronounced increase of serum AST and ALT activities in chronic ethanol‐fed rats, when compared to controls.
