BACKGROUND: Dementia has emerged as a leading public health problem with elderly persons and its early detection is important for treatment in curable cases. Although dementia screening tests are available, they are still complex and time consuming in practice and therefore difficult to use. Our goal was to validate the time and change(T&C) test, a simple, standardized method for detecting dementia in the elderly populations. METHODS: Participants were 59 patients aged 65 years or older at an urban hospital from November 1 to December 31, 2001. The time test evaluated the understanding of clock hands indicating 11:10, and the change test the ability making 1,000 Won from a group of coins consisting one 500 Won, seven 100 Won, seven 50 Won. T&C ratings were validated against a reference standard based on physician`s diagnosis. Test-retest reliability and inter-observer reliability were assessed. RESULTS: The T&C test had a sensitivity of 73.0%, specificity of 90.9%, positive predictive value of 93.1%, and negative predictive value of 66.7%. Test-retest and inter-observer agreement rates were 95% and 95%, respectively. The T&C test was not influenced by education. The time and change tests took a mean of 7.5 seconds and 19.6 seconds to complete respectively, and was acceptable to participants. When timed cut points were added, the T&C test had a sensitivity of 86.5%, specificity of 40.9% and test-retest and inter-observer agreement rates were 77.3% and 81.8%, respectively. CONCLUSION: The T&C test is a simple, accurate reliable, performance-based tool for detection of dementia in the elderly.

Clinical observation was performed on 81 cases who were received exchange transfusion at Ilsin Christian Hospital from January, 1986 to Decrmber, 1990. The results obtained were as follows: 1) Among 6,388 cases of neonatal jaundice, the exchange transfusion was performed on 81 cases (1.27%). 2) There was no sex predominance (male 40, female 41). The birth weight of 75 cases(92.6%) ranged from 2,500 gm 4,000 gm. 3) The most predominant delivery type was normal vaginal delivery (66 cases, 81.5%). Instrumental delivery was 9 cases (11.1%) that was higher than control group (4.2%). 4) Analysing the exchanged 81 cases, sepsis accounted for 28 cases (34.6%) of the total exchanged group:ABO incompatibility 25 cases (30.9%), complicated causes 13 cases(16.0%), unknown causes 12 cases (14.8%) and Rh incompatibility 1 cases (1.2%). 5) Repeated exchange transfusion was required in 12 cases (16.0%). 6) In 20 cases (24.7%), exchange transfusion was performed on 7 days or more after birth. In 4 cases (4.9%), including 1 cases of Rh incompatibility, exchange transfusion was done within 24 hours after birth. 7) The most common organism of sepsis, which was the most predominant etiology of exchange transfusion was E. coli in 12 cases (31.5%). 8) After exchange transfusion, serum bilirubin, Hb and reticulocyte count were decreased by 24%, 22% and 36%, respectively.

Cerebral venous thrombosis is come from thromboplebitis of infectious origin and bland occlusion of cerebral vein by various causes. Although the main cause of cerebral venous thrombosis is thrombophlebitis, the bland occlusion causes it infrequently as a form of an infarct state. We report a case of cerebral venous infarction caused by splenectomy induced thrombocytosis.

Hantaan and related viruses have been implicated as causative agents for a diverse group of human diseases known collectively as "hemorrhagic fevers with renal syndrome" (HFRS). Outbred SD rats obtained within 24 hours after birth were inoculated by intracerebral (the first group) or intramuscular routes (the second group) with 10(9.5)/ml DL50 of Hantaan seed virus suspension in 0.02 ml and 0.1 ml, respectively. Brain, lung, liver, kidney and spleen were used for virus antigen detection by immunofluorecence and histopathologic examination. In the first group, immunofluorescent intensity of virus antigen was increased in all organs (especially brain) and persisted until time of death(day 9). The histopathologic changes were relatively mild in brain and spleen and unremarkable in liver, lung and kidney. In the second group, immunofluorescent intensity of virus antigen was markedly increased in brain until time of death(day 17), but decreased in other organs. The histopathologic findings, such as meningoencephalitis, interstitial pneumonitis with focal hemorrhage, and lymphoid hyperplasia of splenic white pulp were much prominent compared to the first group. However, those of liver and kidney were unremarkable. The chronology of virologic and pathologic findings in Hantaan-infected suckling rats suggests a possible immune-mediated mechanism in disease pathogenesis.

The status of renal replacement therapy in Korea as follows ; 1) The response rate to questionaire was 57.9% of the 226 hemodialysis centers in Korea and data file was sent in the 62.4% of responder. 2) The number of dialysis center was 226 and the number of hemodialysis machine was 3,507 and annual increasing rate were 8,7%, 14.0%, respectively. 3) The total number of ESRD patients was 20,244 and prevalance and incidence of ESRD were 431.9 and 101.1 patients per million population(ppm). 4) The proportion of renal replacement therapy was hemodialysis(HD) 53.3%, peritoneal dialysis(PD) 17.196, renal transplants(KT) 29.5%. 5) The proportion of long-term and elderly patients was markedly increased comparing 1985 (long term dialysis 20% vs. 2%, over 60 year old patients 26.2% vs. 13.8%. 6) The primary cause of renal disease was diabetic nephropathy 34.09o, chronic glomerulone-phritis 20.8%, hypertensive nephropathy 15.7%. 7) The mean BMI(body mass index,' kg/M)in over 18 year old patients was 20.7+/-2.7 kg/M in the HD and 22.23.0 kg/M in the PD. 71.9M of HD patients and 73.2% of PD were in the normal range (18.5-24.9). 8) The fistula survival rate was 6 month 93.4%, 1 yr 91.7%, 3 yr 87.6%, 5 yr 84.7%. 9) The cause of death were cardiac disease 31.8%, miscellaneous 23.5%, vascular disease 17.2%, infection 14.2%, liver disease 1.2%, social cause 5.9%.
