CT has revolutionized the evaluation and management of patients with head injuries. CT is noninvasive and rapidly provides accurate information regarding the presence, extent and nature of intracranial lesions resulting from trauma. We have reviewed the CT scans of 114 patients, who got head injury with confirmed to skull fracture in plain film. The result were as follows; 1. Of all cases, traffic accident was the most frequent cause and in children fall down was more than 50%. 2. Compound linear fracture was the most frequent type fractures in plain skull film. 3. Of all 114 case, epidural hematoma was 16%, subdural hematoma was 18.4%, intracerebral hematoma was14.4%, subdural hygroma was 2.4%, normal finding was 50%. 4. Mortality rate was 13.2%. 5. Fracture was detected by CT about 28.9%, depression fracture was more easily detected in CT. 6. Incidence rate of countercoup lesion was14.0% and mortality rate was higher than same site lesion, 7. The shape of epidural hematoma was biconvex in 75%, planoconvex in 25%. 8. The shape of subdural hematoma was crescentic shape 82.6%, biconvex shape 8.7%, planoconvex shape 8.7%.

The aim of this study was to evaluate the risk factors of recurrences after their first febrile convulsions in infants and young children. Dlinical studies were made on 187 cases of febrile convulsions who were admitted to the Department of pediatrics of wallace Memorial Baptist Hospital from March, 1990 to December, 1992. 1) 63 cases of 187 cases had recurrences after their febrile convulsions. Thus, the recurrence rate was 33.7%. 2) The male to female ratio was 2.1:1. And there were no significant differences in recurrence rates between sexes. 3) The recurrence rate was significantly higher in those whose initial febrile convulsions were developed before first 18 months of life than those whose initial convulsions were after 18 months of age (49.5% vs. 12.5%). 4) The time interval from initial attack to recurrence was within 12 months in 80% of cases. 5) Our study revealed that the seizure characteristics of the initial febrile convulsion are not important as predictive factors about the probability of recurrences. 6) Among the total 187 cases, family history were present in 52 cases (27.8%). And there were significantly higher recurrence rates if their families show the same history of febrile convulsion (63.5% vs. 22.2%). 7) The risk of recurrence was much higher in patients whose first febrile history of febrile convulsion at the same time.

Compared with osteosarcoma of bone, primary osteosarcoma of the soft tissue is very rare. Extraskeletal osteosarcoma is also a highly malignant pleomorphic sarcoma composed of cells exhibiting primarily osteoblastic, and to a lesser extent, chondroblastic differentiation. A case of extraskeletal osteosarcoma in the right sole is presented in a 67 year old male. The patient had noticed a progressively enlarging soft tissue mass, during about 14 months. This sarcoma was located in the soft tissues without attachment to the skeleton, as determined by examination of the X-Ray findings. The mass of right plantar portion was simply excised and pathologically confirmed to be an extraskeletal osteosarcoma. The clinical and pathological features of this sarcoma are described, and brief review of the literature is made.

Subclavian vein catheterization is a well estab1ished technique in adults for central venous pressure monitoring and the infusion of irritant solutions. Its use in small children is less common, preaumably because of technical difficulties in inserting the catheter and the disk of major complications. During cardiac surgery heparinization potentially adds to the risk of hematoma forma-tion. But it is often preferred becauae of the greater stability of the catheter on the anterior chest wall and allows a greater freedom of the neck and upper limb movement. We have experienced 62 open heart surgeries for congenital heart disease between April 14th and Oecember 31th 1986. In 47 children ranging in age from 11 months to 15 years, there was a high succes rate and no morbidity. It is concluded that infraclavicular subclavian vein catheterization is a useful means of measuring central venous presaure and establishing a central infusion line in children undergoing open heart surgery.

The clincopathologic features of microcystic adnexal carcinoma are presented. Microcystic adnexal carcinoma is a recently described, very rare neoplasm characterized by a locally aggressive growth pattern, and as far as we know, only two reports on the microcystic adnexal carcinoma have been published in the Korean literature. Recently we experienced two cases of microcystic adnexal carcimoma occurred in a 32-year-old male and 27-year-old female patient. They had 2.5 x 2.0 x 2.0 cm and 1.2 x 0.9 x 0.9 cm sized, slowly growing mass in the glabella and below the lower lip, respectively. The immunohistochemical staining for CEA antigen stains the glandular structures but not pilar structures. So we thinked that this tumor would be originated from primitive adnexal cells differentiating into both pilar and eccrine structures.

PURPOSE: To provide for popularization of out-patient surgery, we investigated actual problems occurring after minimally invasive surgery in children. MATERIALS AND METHODS: We reviewed the medical records of 132 patients(154 operations) who performed minimal invasive surgery from January, 1996 to June 1998. All problems following operation were identified in terms of kinds, degrees, and their correlations, including fever, pain, nausea, vomiting, and wound condition, etc. RESULTS: The age of the patients were 0.1 to 16 years(mean, 4.5 years). Of 154 operations hydrocelectomy were 84, orchiopexy 41, and they were 81.2% of all. Operation time were 25 minutes to 150minutes(mean, 63minutes). There were 170 postoperative problems including mild ones, among whom 100 patients revealed changes in body temperature over 37.0degrees C and 43 patients high fever over 37.5degrees C and these fevers were resolved spontaneously even with conservative treatment in short duration excluding one patient who took 39.3degrees C sustaining for 3 days and had a mild touch of flu before operation. 5 patients complained severe wound pain to be injected analgesics without actual wound problem such as bleeding or hematoma, etc. One patient couldn`t void urine to need nelaton catherization one time. CONCLUSIONS: With proper selection and strict preoperative preparation of patients, meticulous anesthesia and operation, careful postoperative check and easy call to doctor, there would be no critical problems following minimally invasive urologic surgery in children.

In order to resolve enamel demineralization around orthodontic bracket, fluoride-releasing materials, glass ionomer cements and fluoride-containing resin, were introduced in orthodontic department. There were many studies about their fluoride release, but their results were controversial. The purpose of this study was to clarify the pattern and amounts of fluoride release from glass ionomer cements and a fluoride-containing resin during 70 days in vitro. Disc shaped specimens were prepared and immersed in polyethylene tube containing 2m1 distilled deionized water. The daily amounts of the fluoride released from each specimens were measured after experiment 1 day, 3 days. 7 days, 14 days, 42 days and 70 days. They were measured by fluoride-specific electrode combined pH/ Ion meter. The following results were as follow, 1. Fluorides released from fluoride-containing resin during 1 day were significantly less than those from glass ionomer cements. 2. On experiment 70 days, mean daily amounts of fluoride released from Miracle-Mix(R) were 3.4microgram/cm2, those from Fuji GC II(R) were 2.7microgram/cm2, those from Orthobond(R) were 2.3microgram/cm2, those from Fuji GC LC(R) were 1.4microgram/cm2 and those from fluoride-containing resin, Heliomolar(R), were 0.lmicrogram/cm2. 3. There were no significant differences in daily amounts of fluoride released from between self-curing glass ionomer cements and light-curing glass ionomer cements. Amounts of released fluoride varied among commercially available products. 4. In all experimental materials, amounts of released fluoride decreased rapidly until experimental 3 days and then decreased slowly until 14 days and more slowly until 70 days.
