    A case-control study was conducted to reveal the relative risk of cadaveric dura mater graft transplantation for Creutzfeldt-Jakob disease. Fifty-two cases with Creutzfeldt-Jakob disease that were reported to the surveillance of the disease, and 102 age- and sex-matched hospital controls were selected. Information on family history, occupations, and medical history was collected. Eight cases and no control had a history of cadaveric dura mater graft transplantation. Surgical operations without the dura mater graft, blood transfusion, and acupuncture did not elevate the risk. cadaveric dura mater transplantation, case-control studies, Creutzfeldt-Jakob disease, risk factors.

    Objective. To clarify whether patients with Kawasaki disease have a higher death rate than the age-matched healthy, population after.the disease occurrence. Study design. Between July 1982 and December 1992, 52 collaborating hospitals collected data on all patients having a new definite diagnosis of Kawasaki disease. Patients were followed until December 31, 1997, or death. The expected number of deaths was calculated from Japanese vital statistics data and compared with the observed number. Results. Of 6576 patients enrolled, 25 (19 males and 6 females) died. The standardized mortality ratio (SMR) was 1.35. In spite of the high SMRs during acute phase, the mortality rate was not high after the acute phase for all patients. Although the SMR after the acute phase was 0.76 for those without cardiac sequelae, 6 males (no females) with cardiac sequelae died during this period and the SMR for the male group with cardiac sequelae was 2.77. Conclusion. The mortality rate among males with cardiac sequelae due to Kawasaki disease was 2.8 times as high as in general population, whereas mortality rates for females with the sequelae and both males and females without sequelae were not elevated.

    A nationwide epidemiologic survey of idiopathic hypoparathyroidism and pseudohypoparathyroidism was conducted in 1998 to clarify the prevalence of the two disorders in Japan. From a total of 14, 100 departments of pediatrics, internal medicine, neurology, and endocrinology in whole Japan, 2952 (20.9%) study departments were selected at random. Of these departments receiving the first questionnaire, 1855 (62.8%) responded. From these departments 390 patients with idiopathic hypoparathyroidism and 203 with pseudohypoparathyroidism who visited the hospitals in 1997 were reported. The total numbers of patients were estimated to be 900 (690-1100) for idiopathic hypoparathyroidism and 430 (330-520) for pseudohypoparathyroidism (95% confidence intervals in parentheses). Using these data, the period prevalence of the diseases were 7.2 (5.5-8.8) per million population in idiopathic hypoparathyroidism, and 3.4 (2.6-4.2) in pseudohypoparathyroidism (95% confidence intervals in parentheses).

    By May 1996, 43 cases of Creutzfeldt-Jakob disease with cadaveric dura transplantation were reported during a nationwide survey in Japan. With the assumption that the number of patients receiving the transplantation each year was 20,000, the incidence of the disease among patients receiving cadaveric dura grafts was compared with the annual incidence in the general population. Cumulative incidence was between 0.017 and 0.048%. The estimated relative maximum risk was 104.9, and even the minimum relative risk was as high as 29.2.

    Objective: The purpose of this study was to find whether the number of incidents of Creutzfeldt-Jakob disease has increased during the last decade in Japan. Methods: The chronological trend was observed by examining the data from a nationwide epidemiologic survey conducted by a special committee sponsored by the Ministry of Health and Welfare of Japan in May 1996. The subjects of the survey were patients with Creutzfeldt-Jakob disease who had been diagnosed between January 1985 and May 1996. Although the number of patients reported each year increased continually during the 11-year 5-month period, there were two issues that remained to cast doubt on the accuracy of this apparently obvious chronological trend: (1) the existence of hospitals that did not respond to the survey, and (2) the existence of hospitals where no information was available before a specific time during the observation period. To make up for the incomplete data, the following two methods were proposed: (1) for those hospitals where the precise annual incidence was not known, the average annual incidence for those years when the information was available should be used to make up for the missing data and (2) when a hospital did not have the information for certain years, it would be considered to be a nonrespondent for those years the response rate should be calculated year-by-year then the total number of patients should be obtained by the reported number of patients divided by the response rate. The first method underestimates the annual trend if a trend does exist. To evaluate the trend mathematically, linear regression and quadratic regression models were used, in which the independent variable was the calendar year, the dependent variable, the number of patients. Results: With either method, a trend for increases in incidence was noted. Statistical significance was obtained for the increasing trend in each model. It was found that the quadratic regression model was a better fit than the linear model. Conclusion: The incidence of Creutzfeldt-Jakob disease in Japan has increased during the last decade.

    The projected numbers of patients with diabetes mellitus (ICD 9th 250) 15 years from now were estimated. First, the numbers of patients with the disease in 1984, 1987, 1990, and 1993 were calculated by age and sex using data from the National Patient Surveys conducted by the Ministry of Health and Welfare. Then, population prevalence for calendar years 1996, 1999, 2002, 2005, and 2008 were estimated based on the past data using linear regression models. Finally, the total numbers of patients were calculated from the estimated prevalence multiplied by the estimated population figure of the national government. The prevalence and the numbers of patients are estimated to increase, and the numbers will be 1.7 million among males and 1.5 million among females in 2008. Besides, because of the increases of both the aged population and the disease prevalence, the proportion of patients aged 65 years or over will become as large as 40% of total male patients and 60% of females.

    Background and Methods. It is not certain whether patients with Kawasaki disease have a higher death rate than the age-matched healthy population. We therefore undertook a study to investigate this question. Between July 1982 and December 1988, 53 collaborating treatment centers collected data on all patients who had an unequivocal new diagnosis of Kawasaki disease; patients who had recurrent disease or whose first visit to the treatment center occurred more than 14 days after the onset of symptoms were excluded. Patients were followed from the time of the first visit to the treatment center until December 31, 1989, or until death, whichever occurred first. The expected number of deaths was calculated from Japanese vital-statistics data and compared with the number observed. Results. Of 4676 patients who met the eligibility criteria, 4608 (98.5 percent) were followed through either the end of the study or the date of death. Thirteen patients (10 boys and 3 girls) died during the study period. The number of deaths expected was 7.61 (ratio of observed to expected deaths, 1.71; 95 percent confidence interval, 0.91 to 2.92). The ratio was 2.04 (95 percent confidence interval, 0.98 to 3.76) for boys and 1.11 (95 percent confidence interval, 0.23 to 3.23) for girls. During the acute phase of the disease (the first two months after onset), the ratios of observed to expected deaths were higher: 9.86 overall (95 percent confidence interval, 3.95 to 20.31), 13.33 for boys (95 percent confidence interval, 4.89 to 29.07), and 3.85 for girls (95 percent confidence interval, 0.10 to 21.42). After the acute phase, however, both sexes had ratios of observed to expected deaths that were lower than 1, and the difference from the control population was not statistically significant. Conclusions. The mortality rate among boys with Kawasaki disease in Japan is twice that among healthy boys of the same age, and most deaths occur within two months of diagnosis. The mortality rate among girls with the disease appears similar to that among healthy girls, although the numbers are very small.
