ABSTRACT: A 79-year-old woman with colon cancer and multiple liver metastases was admitted to our hospital for systemic chemotherapy. She underwent first cycle of modified FOLFOX6 chemotherapy. She was confused on treatment day 5. Blood test revealed her serum ammonia level to be 121 microg/dl. We diagnosed 5-fluorouracil (5FU)-induced hyperammonemia. Conservative treatment resulted in improvement of metal status. The reason for hyperammonemia after administration of 5FU was the excess production of ammonium from metabolites of 5FU.

ABSTRACT: There have been few studies on the association between human T cell lymphotropic virus type 1 (HTLV-1) infection and cancer risk. It is still controversial whether or not HTLV-1 infection affects the incidence of several cancers. With this background, we aimed to evaluate the relationship between HTLV-1 infection and the occurrence of several types of cancers.
Subjects were 699 patients with cancer aged 50 years and older diagnosed between 1991 and 2004 at the Department of Medicine and Therapeutics, Ryukyu University Hospital, Okinawa, Japan, and 1365 control patients without cancer. The association between HTLV-1 infection and cancer (biliary tract, pancreatic, esophageal, gastric, colorectal, liver, and lung cancers) was analyzed by logistic regression analysis adjusted for age and sex.
The infection rate of HTLV-1 in patients with gastric cancer was significantly lower than in controls (P = 0.01, adjusted odds ratio 0.46). The infection rate of HTLV-1 was not associated with increased or decreased risk of cancers other than gastric cancer.
Our study indicated that the prevalence of HTLV-1 infection in patients with gastric cancer appears to be significantly lower than that in control patients.

ABSTRACT: We report an atypical case of cat scratch disease (CSD), accompanied with encephalopathy that is a rare complication of CSD. A 17-year old man consulted a doctor for his right axillary lymphadenopathy. The history of his contact with cats and the sign of lymphnode swelling and fever suggested a suspect of cat scratch disease. Administration of ampicillin improved his clinical symptoms, but a few days later he suddenly fell into coma after an episode of convulsion. The CT scan of the brain and laboratory tests showed no significant findings except the slightly elevated cell counts and concentration of protein in his cerebrospinal fluid. He was referred to our hospital on the next day for further examinations and treatments for his coma of unknown cause. The physical examination on admission revealed slight neck stiffening and hypertonicity of his right lower limb, but radiological and laboratory tests showed no significant findings. He gradually recovered from his coma without apparent sequelae in three weeks. Indirect fluorescence antibody titers for CSD in his serum showed a significant elevation to 1:160 of IgM and 1:512 of IgG, and his clinical features were compatible to these of CSD with complications of the central nervous system.
