To date, medical guidance for patients undergoing cancer chemotherapy has mainly been with regard to individual medicines. Only a few reports have been available dealing with information on side effects by a regimen unit. Therefore, we accumulated information on side effects and made a pamphlet for patients with malignant lymphoma undergoing peripheral blood stem cell transplantation after Melphalan (L-PAM), Cyclophosphamide (Endoxan), VP-16 (etoposide) and Dexamethasone (LEED)therapy, for the purpose of explanation for patients on pharmacist's rounds.

In the Nagoya City University Hospital, we started an Anti-cancer drug prescription support system according to which physicians input the injection prescription order from the regimen, together with the Outpatient Oncology Unit established in May, 2007. In order to prepare the anti-cancer drug more safely, we constructed a new Anti-cancer drug preparation support system(new system) at the same time. We investigated and evaluated the time and accuracy required for the preparation between the old and new systems.

The authors report cognitive functions of a 13-year-old boy with a cavernous angioma occupying the posterior left parahippocampal gyrus (PHG) and part of the left fusiform gyrus but not hippocampus. Neuropsychological examinations soon after the removal of the tumor showed selective deficits in semantic memory function, as evaluated by the Category Fluency Task and the Wechsler Memory Scale-Revised, while visual memory, attention, and IQ were not affected. These observations suggest the involvement of the PHG in the processing of semantic memory and provide an insight into the neural substrates underlying the distinct cognitive deficits in some of the psychiatric diseases such as schizophrenia.

Inosine triphosphate pyrophosphohydrolase (ITPase) is an enzyme that catalyzes the conversion of inosine triphosphate (ITP) to inosine monophosphate and pyrophosphate. In Caucasian populations it is reported that the frequency of cases showing decreased ITPase activity is 5%. The structure of ITPA gene along with five single nucleotide polymorphisms has been reported in Caucasians.

Infectious disease surveillance schemes have been established to detect infectious disease outbreak in the early stages, to identify the causative viral strains, and to rapidly assess related morbidity and mortality. To make a scheme function well, two things are required. Firstly, it must have sufficient sensitivity and be timely to guarantee as short a delay as possible from collection to redistribution of information.
