We reviewed the knee radiographs of 68 cases of arthroscopically-proven discoid lateral meniscus to evaluate usefulness of plain radiographs in diagnosing discoid lateral meniscus. The subject included 42 cases of complete type and 26 cases of incomplete type discoid lateral meniscus. Knee radiographs of 70 cases which had no pathology of the meniscus in knee arthroscopy were used as controls. We excluded patients who had a significant history of trauma and who were under 16 years of age or over 60 to avoid measuring radiographs of skeletally immature or degenerative knees. The absolute values and relative normalized values of specific knee dimensions such as a squared-off appearance of the lateral femoral condyle, widened femorotibial joint space, cupping of the lateral tibial plateau, obliquity of the lateral tibial plateau articular surface, high fibular head and hypoplasia of the Iateral intercondylar spine in discoid lateral meniscus and normal controls were compared. Among these dimensions, high fibular head and widened lateral tibiofemoral joint space showed statistically significant difference between the discoid lateral meniscus group and normal control group. We suggest that these findings could be useful in screening lateral discoid meniscus in plain radiographs.

Two hundred twenty premature infants who were inhalated 02 and under 2500mg birth weight or under 37 weeks of gestational age were examined from January 1990 to June 1991. We performed clinical analysis and results were as follows. 1. Thirty one infants (14.1 %) were diagnosed as retinopathy of prematurity. 2. Male patients were 17 (54.8%) and female patients were 14 (46.2%). There was no significant difference in incidence between male and female (X2=0.01, p>0.05). 3. The first examination was performed at 2.4 weeks cf life in average, and the retinopathy of prematurity was diagnosed at 4.8 weeks in average. 4. Stage 2 was detected in 10 patients (32.3%) and stage 3 was detected in 6 patients (19.4%). 5. Plus sign was found in 2 patients (19%) with stage 2 and 6 patients (100%) with stage 3. 6. The incidence of retinopathy of prematurity was highly associated with low birth weight (<1200gm), small gestational age (<30 weeks), and oxygen concentration (>or=60%). 7. Other associated possible risk factors were hyperbilirubinemia, idiopathic respiratoty distress syndrome, anemia, apnea and transfusion.

BACKGROUND: One of the most, probable pathogenesis of vitiliga is autoimmune. Systemic cor tico st,eroids suppress immunity and may arrest the progression of vitiligo and lead to repigmentation. OBJECTIVE: We have assessed the clinical effect of a oral small oral dose of corticosteroid to minimize side effects in vitiligo patients. METHODS: Thirty four patients(9;male, 25;female) with vitiligo were evaluated in this study. The patients took 7.5mg-20mg prednisolone initially for 2 months and then the dosage was tapered to half of the initial dosiat the 3rd month and half of dose of 3rd month for the last 4th month. We compared the effcct of treatment of vitiligo before and aft.er the study by photographs. and side efferts were issessed at. 1, 2, 3 and 4 month. RESULTS: The arrest of the progression of vitiligo was noticed in 79% of patients and repigmentation was noticed in 59% of patients which is statistically significant. The effect, of treatment according to extent, duiation, type, and site of vitiligo were not statistically significant. The side effects of treatment were minimal and did not affect the course of treatment. CONCLUSION: Small doses of iral corticosteroids are effective without any significant side effects in preventing progression and loiiduce repigmentation of active spreading vitiligo and generalized type of vitiligo that is difficult to treat with topical corticosteroids.
