Japanese encephalitis - serial CT findings and neuropathology in an autopsy case.

The patient was a 17-year-old man, who developed Japanese encephalitis in the autumn of 1990 in Japan. He was admitted to our hospital 4 days after onset because of consciousness disturbance. On admission, neurological examination demonstrated left hemiparesis, neck stiffness, and Kernig's sign. He developed generalized tonico-clonic seizure, and required a respirator on the next day of admission. Brain CT 10 days after onset demonstrated hypodensities in the right hippocampus, and the CT obtained 39 days after onset showed whole brain atrophy and hypodensities in the anterior portion of the bilateral thalamus. He died 40 days after onset. Postmortem examination demonstrated perivascular and parenchymal infiltration of lymphocytes and macrophages, proliferation of microglia and astrocytes, and necrosis in the gray matter of the brain. Involvement of the hippocampus and thalamus on CT seemed to reflect the severe lesions characterized by cellular infiltration and necrosis. We discussed for the first time the correlation of CT and neuropathological findings in a patient with Japanese encephalitis.

[Public music concerts in a psychiatric hospital: effects on public opinion and as therapy for patients].

We investigate the effects of music therapy concerts, which were held 60 times over a four year period, 1992 to 1996, in Geiyo Psychiatric Hospital, Kochi Prefecture and found that; 1) Musicians who performed at the concerts were not only from Kochi prefecture but also from other prefectures (10 times) and from four foreign countries (7 times). 2) Live concerts in a small hall had a positive influence on patients and drew the patient's attention and interest away from their hallucinations and delusions to the real world. Moreover, the concerts provided the patients with chances to acquire social graces such as being well-groomed. 3) Explanations by the musicians, interviews with the musicians and the seasonal choruses accompanied by the musicians were helpful to give the patients motives for recovering communication skills and to interact with society. 4) Inquiries to the patients about the concerts indicated discrepancies between the poor observed estimations during the concerts (83.3%) and the good subjective impressions expressed by the patients (82.0%), suggesting that the patients were not good at expressing their internal emotions through facial expressions or attitudes. 5) Many citizens including children came to the concerts and/or gave aid to the hospital because the concerts were open to the public and we suggest that this contributed to improving the general publics' image of psychiatric hospitals. Questionnaires revealed that 90% of people in a control group had a bad image of psychiatric hospitals in Japan, but only 32% of the members of the general public who attended our concerts had a bad image of psychiatric hospitals. In addition, the revolving ratio of the hospital beds rose from 0.4 to 1.2 over the four years, which also suggests a beneficial effect on the patients.
