Neurilemmoma is a benign neoplasm arising from the Schwann cell of the nerve sheath. They are usually painless and are most common in the upper extremity. Pathologically, neurilemmoma is encapsulated and made up of organized elements: the Antoni A cells, the Antoni B cells and the Verocay bodies. Two cases of solitary benign neurilemmoma of the sciatic nerve are presented with a review of the literature. Tumors were completely enucleated and confirmed by pathological examination. The post-operative course has been satisfactory showing no recurrence for the period of more than one year.

The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. The injuries to the ankle joint result in a severe functional disturbance because of complex anatomical characteristics around the ankle joint. 69 patients(72 cases) of the ankle fracture that were treated in Orthopedic Dept. Chonbuk National University Hospital from Jan. 1979 to Dec. 1983 were analized in clinical and radiological aspects. The following results were obtained: 1. Among the 69 patients, male was 54 and female 15 with ratio of 3.5: 1.The average age was 32. 2. Main cause of fracture was traffic accident(58%). 3. The musculoskeletal system was injured most frequently associated with the ankle fracture(66%). 4. According to the ankle fracture classification, the most common type was Pronation-external rotation type in Lauge-Hansen classification, and the type C in Weber classification. 5.The average duration of cast immobilization was 8.8 weeks in closed reduction and 7.4 weeks in open reduction. 6. The lateral malleolar fracture involving the distal tibiofibular syndesmosis was very important in ankle stability so accurate anatomical reduction by internal fixation was necessary for satisfactory functional results. 7. In clinical and radiological analysis, the better results were obtained from open reduction.

The following case of solitary bone cyst of the proximal femur was misdiagnosed as fibrous dysplasia because of similarity of X-ray findings and was confirmed by histological findings. The cyst was treated by curettage, packing with autogenous iliac bone and kiel bone graft and internal fixation with Ender nail. The most recent evaluation one year after surgery showed no pain and recurrence.

In the orthopedic Department of Jeonbug National University Hospital, twenty-five open tibial shaft fractures were reviewed and analyzed with osteomedullography and bone scanning with radioactive isotopes from June 1981 to October 1983. The results are as follows. 1. The cases of injury were mostly traffic accident(70.8%) and majority was found between second decade and third decade. Males were 11 times more frequent than females. 2. In the shape and location of fractures, comminuted fracture(60%) was most common, and fracture of middle one third(48%), lower one third(28%) were in order. 3. In the open tibial fractures, Grade I. of soft tissue injury was most frequent(64%). As inthe plate fixation was required, we should it placed atypically on the posterior surface of the tibia. 4. In the osteomedullography at 3 months after treatment, the rate of positive finding was 80 and intraosseous crossing vein(Kaski sign 1) was observed most frequently. 5. In the profile of the bone scanning with radioactive isotopes, the rate of single-peak uptake was 76% and twin-peak uptake was 24%. 6. In the negative Osteomedullogram and twin-peak uptake on the profile of the bone scanning, bone graft was necessary. 7. In the case of difficult diagnosis for union process of tibia fracture, osteomedullography and bone scanning with radioactive isotopes were considered useful method of early diagnosis.

Intraventricular hemorrhage is a common hemorrhagic cerebral disorder in premature, but occurs much less frequently in the full-term newborn. In order to obtain documentation of clinical and ultrasonographic characteristics of intraventricular hemorrhage in full-term, we performed cerebral ultrasonography on 602 newborn infants who had been admitted to neonatal intensive care unit at the Deppartment of Pediatrics, Yonsei University College of Medicine between December 1989 and June 1991. 15 cases (2.5%) of intraventricular hemorrhage were analysed. The results were as follows: 1) Among 15 cases with intraventricular hemorrhage, there was no obstetrical and perinatal complication in 8 cases (53%) and 13 cases (87%) were neurologically normal at birth. 2) Sudden onset of dramatic neurologic abnormalitis inclued seizures, fever, bulging fontanel, irritability, lethargy, vomiting in cases (73%) and the remainder (27%) had no clinical symptoms and signs. 3) The age at diangosis of hemorrhage was before 72 hours in 5 cases (33%), between 4 and 7 days in 2 cases (13%), at 8 to 28 days in 8 cases (53%), 8 of 15 cases (53%) had Grade 1 IVH, four with Grade 2, cases with Grade 3, and 1 case of these infant demonstrated Grade IV IVH. The source of hemorrhage was subependymal germinal matrix in 12 cases (80%) and choroid plaxus in 3 cases (20%). 4) Precipitating factors were cerebral venous infarction in 7 cases, hypoxic injury in 5, and 3 other infants had no identifiable medical risk factors. 5) Among all 15 survivors, 2 of 3 infants with choroid plexus hemorrhage required placement of a ventriculo-peritoneal shunt, in the other case, ventriculomegaly decreased spontaneously.

The antihypertensive effect of acebutolol was observed in 26 cases of essential hypertension, and following results were obtained. 1) Mean decrease in systolic and diastolic blood pressure by oral acebutolol was 21mmHg and 11mmHg. The results of antihypertensive therapy revealed good control in 30.8%, fair control in 34.6%, poor in 11.5% and failure in 23.1% of the cases. In 65.4% of the cases, good or fair control of hypertension which means drop of diastolic pressure to the level of less than 100mmHg was observed. 2) Mean drop in heart rate was 7/min. 3) Average daily dose was 508+/-171.9mg. 4) The side effect of oral acebutolol was mild gastrointestinal discomfort in two cases.

The brachial plexus injury causes a catastrophic loss of functions of the corresponding upper extremity. However, for a long time, it must have been treated by conservative methods. Recently, with the development of the microsurgery, the brachial plexus lesions were begun to be treated by surgical means, such as neuroiysis, interfascicuiar nerve graft, or neurotization. We experienced seven cases, managed by interfaseicular nerve graft under the operating microscope, and here we presented four cases with the over-one-year results after operations.
