[Development of a user-friendly laboratory information system].

We developed user-friendly laboratory information system based on the responses of users who were shown many versions of prototypes. This method was applied to the development of on-line computer systems used by laboratory staff, and resulted in a decrease of difficulty using the systems, an improvement in the productivity of laboratory staff, and a decrease in the time needed for developing the systems.

A case of gallbladder cancer manifesting chylous ascites and chylothorax.

A case of gallbladder cancer manifesting both chylous ascites and chylothorax was reported. A 66-year-old man was hospitalized with milky ascites. The patient was diagnosed as having gallbladder cancer based on findings of endoscopic retrograde cholangiopancreatography (ERCP) and celiac angiography. The diagnosis of chylous ascites was confirmed by the presence of microscopically visible free fat and the biochemical analysis of the fluid. The patient also gradually developed chylous thoracic effusion. Autopsy revealed lymphogenous metastasis in multiple retroperitoneal and mediastinal nodes. Chylothorax and chyloperitoneum are relatively rare. Only five cases have been reported in Japan that manifested both conditions.

HBs antigen subtypes among acute hepatitis patients in Japan: evidence of imported hepatitis.

HBs antigen subtypes were determined among 137 acute hepatitis patients in Japan. The distribution among the 99 male patients was 40 adr, 37 adw, one ayw, and 21 undetermined while that among the 38 female patients was 19 adr, 11 adw, and eight undetermined. The distribution among the male patients was different from that among HBs antigen carriers in Japan, suggesting that they were exposed not only to domestic HBs antigen carriers, but also to other sources. Thirty-one (29 males and two females) of the 137 patients (22.6%) were found to have been abroad at some time during the incubation period. The distribution among them was seven adr, 21 adw, and three undetermined. The majority had the same subtypes that are prevalent in the countries they visited, supporting the hypothesis that most of them had contracted the disease overseas. The remaining 106 patients had a distribution of the subtypes similar to that of domestic HBs antigen carriers. "Imported hepatitis" would be an important cause of acute type B hepatitis in Japan.

Percutaneous ethanol injection in the treatment of liver neoplasms.

The effectiveness of percutaneous ethanol injection therapy was investigated in 30 patients who had hepatocellular carcinoma (18 had a single lesion and 12 had multiple lesions). In patients who had a single lesion, ethanol injection was especially effective. Histopathologic examination, performed in nine cases in this group, showed that the tumor was completely necrotic in six cases, 90% necrotic in two cases, and 70% necrotic in the remaining case. In eight other cases with a single tumor, follow-up angiography showed complete disappearance of the tumor stain. In the other case, CT showed the nonenhanced low-density area. In the 12 patients with multiple lesions, ethanol injection was performed as part of an integrated treatment plan. Eleven were still alive at the end of the study (the mean follow-up period was 5.8 months). We conclude that ethanol injection may be a valuable treatment for hepatocellular carcinoma.
