Purpose: We measured T 1 and T 2 values of cerebral postmortem magnetic resonance (PMMR) imaging and compared the data of cadavers with that of living human subjects.Materials and Methods: We performed PMMR imaging of the brains of 30 adults (22 men, 8 women; mean age, 58.2 years) whose deaths were for reasons other than brain injury or disease at a mean of 29.4 hours after death. Before imaging, the bodies were kept in cold storage at 4°C (mean rectal temperature, 15.6°C). We measured T 1 and T 2 values in the brain bilaterally at 5 sites (bilateral caudate nucleus, putamen, thalamus and gray matter and white matter of the frontal lobe) and compared the data of PMMR imaging with that from MR imaging of the corresponding sites in 24 healthy volunteers (9 men, 15 women; mean age, 51.8 years). We also investigated the influence of body temperature on T 1 and T 2 values.Results: Compared with MR imaging findings in the living subjects, PMMR imaging showed significantly shorter T 1 values in the caudate nucleus, putamen, thalamus and gray matter and white matter of the frontal lobe and significantly longer T 2 values in the gray matter and white matter of the frontal lobe; T 2 values in the caudate nucleus, putamen, and thalamus showed no such differences. T 1 values correlated significantly with body temperature in all 5 brain sites measured, but T 2 values did not.Conclusion: Compared with findings of cerebral MR imaging in living adult subjects, those of PMMR imaging tended to demonstrate shorter T 1 values and longer T 2 values. We attribute this to increased water content of tissue, reduced pH, and reduced body temperature after death.

This results suggested that the stone number, stone history and urological complication were highly related to ipsilateral stone recurrence after stone free status by ESWL. Extracorporeal shock was lithotripsy had probability of higher stone recurrence rate.

Long-term results were analyzed in terms of tumor progression and survival in patients with superficial bladder cancer who were enrolled in the second intravesical chemoprophylactic study of the Japanese Urological Cancer Research Group for Adriamycin, which was started in July 1982. This study was a prospective, randomized, controlled trial conducted on primary tumors treated with a long-term instillation regimen that involved control versus intravesical instillations of Adriamycin or mitomycin C given once a week for the first 2 weeks, once every other week for 14 weeks, once a month for 8 months, and once every 3 months for 1 year, for a total of 21 instillations in 2 years. An analysis of the prophylactic effects of such treatment on bladder tumors after TUR has previously been performed, and the results have been published elsewhere. The present study represents a follow-up of the above trial. Of the 671 cases previously analyzed with regard to tumor prophylaxis, 158 cases (23.5%) were eligible to be followed for tumor progression and survival. A detailed comparison of the background factors between these 158 patients and the other 513 cases revealed no statistically significant difference. Thus, the 158 evaluable cases might reasonably be considered to represent all patients enrolled in the second study, and the results were thought to be reasonable enough to reflect the long-term efficacy of the long-term instillation regimen adopted in this study. The median follow-up for these 158 cases was 6.6 years. Tumor progression in terms of the disease stage and/or grade occurred in 43 of 127 patients who received prophylactic instillations and in 12 of 31 control cases. No significant difference in the incidence of tumor progression was found between the treatment and the control groups. In addition, no difference in survival was observed between the treatment group and the control group. Survival was also compared between patients who showed tumor progression and those who did not. All patients whose tumors did not progress survived, whereas the 7-year survival of those exhibiting tumor progression was less than 90%.

In Japan, freeze-dried live attenuated mumps vaccine has been used optionally since 1981. The effectiveness of mumps vaccination has been established by worldwide research since 1971. On the other hand, because of it' s live activity several untoward effects have been reported. Vaccination-related mumps orchitis is a rare adverse effect of mumps vaccine. Only 9 cases of vaccination-related mumps orchitis have been reported in Japan. We describe a case of orchitis following mumps vaccination in adolescence. A 16 years-old male has admitted because of acute orchitis with high fever and painful swelling of right testis. The patient had received vaccination with freeze-dried live attenuated mumps vaccine 16 days before admission. After admission, the bed-rest had completely relieved the symptoms on 6th hospital day. The impaired testis has maintained normal size and consistency 6 months after discharge.
