Primary Central Nervous System Lymphoma(PCNSL): Treatment Result of 23 Cases

The authors report below a clinical study of 23 patients bearing 31 primary central nervous system lymphomas diagnosed between January 1985 and December 1994. The cohort included 13 men and 10 women whose mean age was 46 years, ranging from 28 to 61 years. No patient had antecedent of human immunodeficiency virus positivity but one had a past history of rheumatoid arthritis. The duration of symptom was less than 8 weeks in 52% of the patients. Symptom groups included increased intracranial pressure(78%), focal neurological decificit(52%), neuropsychiatric symptoms(43%), and seizures(13%). The histopathologcal diagnosies were done in 19 cases(10 cases by resective surgery, 9 cases by open or stereotactic biopsy). The others were diagnosed by the typical clinical course such as rapid disappearance of lesions after steroid therapy, and/or radiological findings. Histological subtypes(National Cancer Institute Working Formulation) was confirmed in 8 patients including 3 cases of diffuse larger cell type. Phenotype was determined in 7 patients: 4 were B-cell type and 3 were T-cell type. One patient committed suicide during the radiation therapy and was therefore excluded from the survival analysis. All but two patients received radiation therapy. Five patients received chemotherapy. The over-all Kaplan-Meier survival rate was 46% at 2 years and 15.5% at 5 years. On univariate analysis, statistically significant prognostic factor associated with survival was not found but the higher Karnofsky score and single lesion were found to be favorable to the long-term survival. In the statistical analysis of the patients who received radiation therapy, surgical resection did not significantly influence the survival.

A Clinical study of Flexion Contractures of the Injured Fingers / 대한정형외과학회잡지

One of the commonest and most serious problems of the injured hand is flexion contractures of the fingers. Such deformities not only functionally impair the digit, but also reduce or restrict the functional capability of the entire hand. We reviewed 150 digits of 73 patients with flexion contractures of the fingers which had been treated at National Medical Center from Jan. 1976 to Dec. 1985. The results were as follows: 1. The duration of flexion contractures which were scattered from 4 months to 17 years and average duration of contracture was 20.6 months. 2. The methods of treatment were Z-plasty, adhesiolysis, capsulotomy, excision of both collateral ligaments, stripping of extensor mechanism and volar plate and release of flexor tendon sheath according to injury mechanism and duration of contracture. 3. The postoperative results showed up 32 (21.3%) excellent, 78 (52%) good, 24 (16%) fair and 16 (10.7%) poor. 4. The postoperative results of burned injury which showed up-8 excellent, 11 good out of 20 cases they are supposed to have satisfactory results. 5. Crushing injury which had intraarticular fracture or comminution show up unsatisfactory results. 6. It seems obvious that the early active motion of interphalangeal joint is important to improve joint function. 7. The arc of motion was retained in a more functional position postoperatively than preoperatively.
