PURPOSE: To analyze the variable MRI features and clinical significance of intracranial cavernous realformation. MATERIALS AND METHODS: Forty patients(mean age 35.4) with cavernous malformation were evaluated by MRI. Eleven patients were surgically confirmed. Cavernous malformations were divided into four categories on the basis of the MR imaging characteristics, especially on T2-weighted image. Type I lesion was defined as an extralesional subacute hemorrhage outside the low signal rim, type II as an intralesional hemorrhage surrounded by low signal rim, type III lesion as an intralesional thrombosis with variegated central core surrounded by low signal rim, and type IV lesion as a focal old hemorrhagic core with small low signal intensity. Type IV was further divided into IVa and IVb, whether the lesion has small iso- or hypersignal central core (IVa) or not (IVb). Follow-up MRI was evaluated in 12 patients who were managed conservatively. Follow-up intervals ranged from 2 weeks to 29 months (mean 6months). RESULTS: Total 80 lesions were detected in 40 patients. Multiple lesions were noted in 10 patients. The topography of the cavernous malformations was supratentorial in 75% and infratentorial in 23%. There were 10 lesions in type I, 15 in type 11, 21 in type III, 14 in type IVa, and 20 in type IVb. Type I lesions mainly showed mass effect and edema. Type III lesions showed minimal contrast enhancements in 7 lesions on delayed images. Type II lesions showed the characteristics of both type I and type III lesions. On follow up images, decrease in size in 5, change of type in 7, rebleeding in 2 and no change in 12 lesions were demonstrated. Hemorrhage, edema and mass effect were combined in the cases of rebleeding. On follow-up study, the estimated risk of bleeding was 32.3%/person-year and 13.7%/lesion-year. CONCLUSION: Cavernous realformations show as variable appearance, on MR imaging suggesting variable stages of evolution. The MR morphologic classification and evaluation of secondary findings are helpful to predict natural course and possibility of rebleeding of the lesion.

This mycological and cultural investigation was made in 86 cases of onychomycosis diagnosed on positive KOH wet mount at Chosun University Hospital from October, 1989 to February, 1990. The results were as follows : l. The ratio of male to female was 1.2:1. According to Zaiass classificat.ion, distal subungual onychomycosis (DSO) was the most predominant type(79 cases) and others, in decreasing frequency, were superficial white onychomycosis (SWO) (Fcases), total dyst,rophic onychomycosis (TDO) (1 cases, and proximal subungual onychomycosis (PSO) was not. found. 2. In DSO, isolat,ed fungi were T. mentagrophyte(31 cases), "i'. rubrum(23 c

Supracondylar osteotomy was performed on 78 knees in 65 patients with poliomyelitis for correction of deformities of the knee at the Department of Orthopedic Surgery, Seoui National Unlversity Hospital, during the 16 years from January 1963 to December 1978. Following observations were made from the review of statistics, technical problems, and complications of the operation. 1. The ages of the patients ranged from 4 years to 28 years, the average being 15 years. Two thirds of the patients were in the second decade. 2. 37 knees (47.4%) had flexion deformity, 19 knees (24.4%) flexion-valgus deformity, and 13 knees (16.7%) flexion-valgus-external rotation deformity. The amount of flexion deformity ranged from 7 degrees to 90 degrees, the average being 22 degrees. Valgus deformity ranged from 3 degrees to 25 degrees, the average being 12 degrees. External rotation deformity ranged from 5 degrees to 30 degrees, the average being 18 degrees. 3. The operative techniques employed were categorized into 5 types. The most common type was a closed wedge hinged osteotomy (Technique I), which was employed on 50 knees (64.1%). Satisfactory results were obtained by combining other procedures, when necessary, i.e. pre-operative skeletal traction, Yount fasciotomy, high tibial rotation osteotomy hamstring transfer and epiphysiodesis. 4. The time required for union was the shortests in the Technique 1 group, and longest in the Technique III group, a complete osteotomy with bone shortening. 5. The most common complication was stiff knee, which was encountered in 10 knees. Residual or recurrent deformity was observed in 4 knees, in 3 of which hamstring transfer was recommended but was not consumated. Delayed union was observed in 3 knees in the Technique II group (closed wedge complete osteotomy) and in 1 knee in the Technique III group. Nonunion occured in 1 knee in the Technique II group. The incidence of complications were higher in the Technique II and III groups, and lowest in the Technique I group.

PURPOSE: It has been known for a long time that infants of insulin dependent diabetic mothers are prone to develop macrosornia, organomegaly, hyperbilirubinemia, respiratory distress syndrome, hypoglycemia, hypocalcemia, septicemia and congenital anomalies in the neonatal period. And echocardiographic asymmetrical- ventricular septal hyper- trophy(ASH) has been observed in the newborn infants of diabetic mothers. The etiology of the ASH remains unknown, although fetal hyperglycemia and subsequent glycogen deposits have been postulated as contributing factors. Therefore, we have studied whether large for gestational age(LGA) has played an important role of developing ASH. METHODS: We compared echocardiographic findings in neonates of LGA and appro- priate for gestational age(AGA), who were admitted to the Department of Pediatrics, Chung Ang University Hospital from April 1994 to March 1997. RESULTS: 1) Mean LVED in LGA and AGA were 1.96+0.06cm and 1.94+0.04cm, respectively. 2) Mean LVPW in LGA and AGA were 0.37+0.05cm and 0.370.05cm, respectively. 3) Mean IVS in LGA and AGA were 0.400.09cm and 0.380.09cm, respectively. 4) Mean IVS/ LVPW in LGA and AGA were 1.09+0.12 and 1.040.17, respectively. There was no statistical significance between two groups in echocardiographic findings. CONCLUSION: There is no relation between LGA and ASH in the neonate. According- ly, we may not need to perform echocardiography LGA routinely.
