ReviewReport of the 1997 Asia Pacific Consensus Conference on the management of Helicobacter pylori infection.
While European and United States guidelines for the management of Helicobacter pylori infection have been developed, there are no guidelines for the Asian Pacific. International experts and recognised local authorities met in Singapore in 1997 to develop appropriate guidelines, taking into account the high background prevalence of infection, high incidence rates of gastric cancer and resource limitations. Recommendations were made based on randomised controlled trials or where this was not possible, they were based on the current best available evidence or on good clinical practice. ⋯ Treatment regimens need to attain an eradication rate of 90% or greater by per protocol analysis and 80% or greater by intention-to-treat analysis. A number of 7-day regimens were recommended based on available evidence. These regimens were considered likely to maximize the chances of successful eradication with one course of treatment, thereby reducing the risk of acquired antibiotic resistance and leading to long term cost savings.

A prospective clinical study of isoniazid-rifampicin-pyrazinamide-induced liver injury in an area endemic for hepatitis B.
In order to evaluate the incidence, predisposing factors and clinical course of antituberculous drug-induced liver injury in hepatitis B surface antigen (HBsAg)-positive carriers and non-carriers, in an area endemic for hepatitis B, we prospectively followed 240 patients (154 male, 86 female; mean age 40 years) who had received daily isoniazid, rifampicin, ethambutol and pyrazinamide for the treatment of pulmonary tuberculosis. Patients with heavy alcohol consumption, with pretreatment serum alanine aminotransferase (ALT) elevation and who had less than 3 months post-treatment follow-up were excluded from the study. Thirty-one (13%) patients were positive for serum HBsAg before treatment. ⋯ Only one 61-year-old HBsAg carrier developed severe jaundice after 6 months antituberculous therapy; he subsequently died of hepatic failure. In conclusion, the incidence of antituberculous drug-induced liver injury was significantly higher in patients > 35 years of age than in patients < or = 35 years of age, but was not different between HBsAg carriers and non-carriers. Mortality occurred in an aged HBsAg carrier superimposed with antituberculous drug-induced liver injury.

Case ReportsCase report: acanthosis nigricans in association with primary biliary cirrhosis: resolution after liver transplantation.
A case is described of a 58 year old Caucasian male with primary biliary cirrhosis (PBC) who first presented with acanthosis nigricans of both axillae, skin pigmentation, which was pronounced over the posterior surface of the neck, and generalized pruritus. Following orthotopic liver transplantation for progressive liver disease, the skin pigmentation, pruritus and acanthosis nigricans resolved. It is believed that this is the first reported case of acanthosis nigricans occurring in association with PBC, a phenomenon that resolved after liver transplantation.

Potentiation of carbon tetrachloride-induced liver damage by dibutylyl-3',5'-cyclic AMP in unstarved rats.
It has been reported that carbon tetrachloride-induced liver damage is potentiated by starvation partly due to fat accumulation in the liver and a decrease in hepatic reduced glutathione concentration and that dibutylyl-3',5'-cyclic AMP (DBcAMP) affects fuel metabolism and decreases hepatic reduced glutathione. We investigated the effects of DBcAMP on carbon tetrachloride-induced liver damage both in unstarved and starved rats. In unstarved rats, intraperitoneal administration of DBcAMP potentiated an increase in serum alanine aminotransferase activity and fatty vacuolization in the liver, both of which were induced by carbon tetrachloride. ⋯ It was suggested that DBcAMP potentiated carbon tetrachloride-induced liver damage in unstarved rats, probably due to hepatic fat accumulation and a decreased hepatic reduced glutathione concentration. The former could increase the affinity of the liver for carbon tetrachloride and the latter could accelerate carbon tetrachloride-induced lipid peroxidation. It was also suggested that DBcAMP failed to affect carbon tetrachloride-induced liver damage in starved rats, probably because starvation had already decreased hepatic glutathione concentration and DBcAMP had different effects on fuel metabolism compared with effects observed in unstarved rats.

Case ReportsLaparoscopic observation of retroperitoneal cystic lymphangioma.
A case of retroperitoneal cystic lymphangioma observed laparoscopically is reported. In a 60 year old asymptomatic male patient, an 8 cm multi-loculated cystic lesion was detected incidentally near the splenic hilum with ultrasonography. Endosonography, computed tomography and magnetic resonance imaging revealed the lesion with thin wall and clear fluid. ⋯ The tumour was resected, and microscopic examination showed proliferated lymph channels intespersed by lymph follicles. Diagnosis of cystic lymphangioma was established. Laparoscopy seems a useful pre-operative method.
