The posterior cruciate ligament(PCL) is one of the most important structures in the knee joing because it provides about 94% of the total restraint to posterior displacement of the tibia & posterior stability of the knee joint. If the posterior instability persisted, rotational instability, injury to meniscus and degenerative change develop within several years. The purpose of this study is to know the result of the posterior cruciate ligament reconstruction using semitendinosus tendon and to know the factors which affected to good result. During the period from January 1989 to December 1994, 16 cases with posterior cruciate ligament reconstruction using semitendinosus tendon were evaluated clinical and radiological results retrospectively and performed stastical analysis using the SPSS. The results were as follows; 1. The average preoperative posterior laxity was 14.1 mm and average postoperative laxity was 6.3 mm. It was improved 7.8 mm. 2. In other associated injured ligament group with or without fracture, above good was in 8 cases and below fair in 6 cases, but there was no significant difference between the two (X²=9.8, df=1, P>0.05). 3. In the poor result group, mean body weight was 80(±13.23)kg and there was significant difference between poor group & fair, good, excellent group(F=3.52, P < 0.05). From these results it would be suggested that PCL reconstruction using semitendinosus tendon is more effective in relatively light weighted group than heavier group.

OBJECT: Pre-ALL is a very rare preteukemic state, which percedes acute lymphocytic leukemia, while MDS(pre-ANLL), usually the well-known type of preleukemic state, precedes acute non-lymphocytic leukemia. Initially it shows transient pancytopenia without any evidence of leukemia in bone marrow findings, followed by acute lymphocytic leukemia after recovery from pancytopenia of a short period within weeks or months. We report a case with pre-ALL in childhood. CASE: A 15-month-old male baby was admitted with the complaints of fever and cough for 5 days and pallor for 2 weeks prior to admission. On admission, CBC showed pancytopenia without any evidence of leukemia, which was recovered spontaneously in a short period, and then was followed by acute lymphocytic leukemia of CALLA negative, early pre-B cell type. During antileukemic chemotherapy, he had suffered from severe bacterial infections and was finally died of sepsis 8 months after first admission. CONCLUSION: We report a case of pre-ALL in childhood, which was preceded by CALLA negative, early pre-B cell ALL, with a review of the literatures, briefly.

BACKGROUND: Alzhiemeranjx disease (AD) and vascular dementia (VD) are common types of dementia. As a result of the development of new specific agents for AD, and because vascular dementia is a potentially preventable dementia, differentiating these diseases is of great importance. The role of EEG spectral analysis in the differential diagnosis between Alzheimer type and vascular dementia is still controversial. Since there have been few studies concerning the differential diagnosis of dementia by EEG, the present study has focused on this aspect. Usefulness of EEG in differen-tial diagnosis of dementia will be elucidated by clarifying relationship between type of dementia and spectral profile of EEG. METHODS: We analyzed the power spectra taken from 16 derivations and spectral profile was constructed by averaging twenty 2 sec epochs in three study groups (normal controls, AD and VD). Spectral profile was divided into three groups; (I) type A, showing a dominant 6.5-12 Hz peak (ii) type B, lacking a dominant peak in the 6.5-12 Hz (iii) type C, corresponding to a flat, low voltage, spectrum. To elucidate the relationship between spectral profile and other factors including diagnosis, statistical test was done. RESULTS: (1) In AD, type C profile was statistically more prevalent than in VD and type A profile was reversed. (2) In AD, Mini-Mental State Examination (MMSE) score was statistically lower in type C profile. (3) Spectral profile was not associated with age, age of symptom onset, and symptom duration. CONCLUSIONS: This study suggested that spectral profile is a useful tool for the differential diagnosis of dementia (AD and VD) and correlated with the severity of disease in AD.

BACKGROUND: The SF-6D, derived from the SF-36, is a preference-based instrument measuring health-related quality of life (HRQOL). Using this tool, we measured the HRQOL of persons disabled by stroke dwelling in Gyeongju city and identified factors affecting the HRQOL. METHODS: As of March 2008, 991 persons who had had a stroke and were aged 50 and over were identified on the Gyeongju city disabled registry. Interviewers specifically trained for this face-to-face survey gathered pertinent information including general and clinical characteristics from June to October 2008. In addition, the health status was measured using the Modified Rankin Scale, the Barthel ADL index, and the SF-36. The SF-6D index was derived from the SF-36. We analyzed the known-group construct validity and convergent validity. Finally, we performed multiple regression analyses to identify factors affecting the HRQOL. RESULTS: Of the 991 potential subjects, 498 persons participated in the interviews (response rate: 50.3%). The SF-6D indices for females and those aged 70 and over were lower than indices for males and those aged 60 and less. Correlation coefficients between the Modified Rankin Scale, the Barthel index, and the SF-6D index were relatively high (-0.533 and 0.555, respectively) and statistically significant (P<0.001). Multiple regression analyses showed that sex, age, smoking, alcohol use, comorbidity, the Modified Rankin Scale, and the Barthel index had an effect on the SF-6D index of persons with stroke, and the Barthel index was the most important factor. CONCLUSIONS: Our results indicate that the SF-6D can be a valid tool for evaluating health states of persons disabled by stroke, and functional limitation was the main factor affecting the HRQOL.
