RESUMEN
@#A review of serum prostate-specific antigen (PSA) values from January 1994 to May 1997 and their correlation with the histopathology of prostate specimens was carried out in the Department of Pathology, Port Moresby General Hospital. The study has shown that this biochemical investigation has not been properly used for the maximum benefit of the patient population. Remedial measures are suggested to improve the sensitivity and specificity of PSA in a setting with limited resources.

@#Intestinal infarction is a rare complication of systemic lupus erythematosus (SLE). A 26-year-old Papua New Guinean female who developed such a complication and underwent emergency laparotomy is described. The pathological changes in the mesenteric vessels and possible pathogenetic mechanisms are discussed. The relevant literature is briefly reviewed.
RESUMEN
@#Twenty years after the first surveys of liver disease were done cirrhosis and hepatocellular carcinoma were still found to be the most important liver diseases in Papua New Guinea. Hepatitis B virus appears to be the main cause of both these conditions. Data from a number of different sources suggest a prevalence of hepatitis B positivity of about 17%. The most significant new finding was grade 3 iron deposition in 8 patients. This raises the question as to whether iron storage disease may now contribute to the spectrum of liver disease in Papua New Guinea. Many biopsies in the 1960s and 1980s were interpreted as nonspecific hepatitis; in the light of recent observations, at least some of these may have been due to hepatitis C infection.
