Twenty seven fractures of the femoral neck in 26 elderly patients treated by primary replacement with the endoprosthesis were reviewed. The end results of 18 hips of 17 patients who were followed up at least over 6 months were as follows. The average age was sixty-seven years. Seventeen fractures occurred in women and ten in men. Of these 18 hips, eleven hips were excellent or good. Poor results were in two hips; one developed deep seated infection and the other patient who could walk with crutch after bilateral endoprosthetic replacement because of Lt hip pain. It is considered that this method is the best treatment in the rehabilitation of elderly patients after high femoral neck fracture, because of its low morbidity and high success rate in returning the geriatric orthopaedic patients to independence.

Ninety six patients treated at Seoul Red Cross Hospital from Jan. 1979 to Dec. 1982 were analized in clinical and radiological aspect. The results obtained from this study were as followings; 1. Among the 96 patients, male was 67 patients and female was 29 patients (M:F=2.5:1). The average age was 32. 2. The causes of the injury were traffic accident, slipping down, falling down and sports injuries in orders. 3. According to the classification of Lauge-Hansen, supination external rotation type (38.5%) was the most common type. 4. 65 cases (67.7%) were treated by open reduction and 31 cases (32.3%) by closed reduction. The better result was obtained by open reduction than closed reduction. 5. Accurate reduction and rigid internal fixation of the lateral malleolus was most important in treatment of the ankle fractures. 6. Classification of Lauge-Hansen was useful in diagnosis and treatment of the ankle fractures.

BACKGROUND: Care for prehospital cardiac arrest is one of the major concerns of emergency medical services. But, in Korea, prehospital emergency medical service systems are not yet well established. We tried to offer one of the fundamental data for development of these systems. METHODS: After application of exclusion criteria, 183 patients who transferred to emergency center of our hospital after cardiac arrest in consecutive 24 months from Jan,1,1994 to Dec,31,1995 were included in this study. Retrospective review of the hospital charts of these patients was done. For statistical analysis, we divided patients to some categories. t-test or chi-square analysis was used. RESULTS: 24 patients of the 183 patients were secondary visitors(cardiac arrest was occurred during transfer from other hospitals), 159 patients were primary visitors. In the primary visitor group, only one third was ambulance visitors, and there is no statistical differences between arrest time of ambulance visitors and non-ambulance visitors(35+/-27 vs 37+/-24 min, p=NS). No organized bystander CPR was done. After arrival, 131 patients received CPR and 87 patients(66.4%) were not responded, 31 patients(23.1%) experienced transient ROSC, 13 patients(10.0%) survived until discharge, and only 2 patients(1.5%) were returned to their lives. CONCLUSION: We failed to find significant statistical survival differences between ambulance visitors and non-ambulance visitors, between presumed cardiac etiology group and non-cardiac etiology group. Survival rate was high in witnessed arrest group than unwitnessed arrest group(14.5% vs 2.1%, p=0.015).

The fabella, a sesamoid bone that occasionally is found in humans on the gliding surface of the lateral head of the gastrocnemius, is a sign of an atavistjc pattern. The authors examined radiograph of knees of 817 patients for the presence of fabella and determined the incidence of fabella in traumatic patients as compared with non-traumatic patients with primary osteoarthrosis or vague pain in that knees. The results were as followes: l. 31.0% of 626 adult patients had at least a unilateral fabella. 2. There was no difference in the incidence of fabella according to sex (p<0.01). 3. The youngest boy showing the fabella was aged 12 years & 8 months, the youngest girl 15 years & 2 months. 4. 87.1% of the patients who had a fabella had one bilaterally. 5. Fabellae were more common in the patients with primary osteoarthrosis or vague pain in that knees. 6. It is our opinion that the presence of fabella is more important in the clinical aspect in Korea.

The wrist joint is exposed to trauma easily which is a small portion of human body. Because there are many structures(tendons, vessels and nerves) in the wrist, it is necessary to examine carefully and treat properly when it is damaged. We have treated 230 cases of soft tissue injuries around the wrist and the result can be summarized as follows; 1. Among the 230 cases, the male ratio was 85% and the highest incidence was in the third decade. 2. Right side injuries were more than left and flexor surface injuries were more than extensor surface. 3, The main cause of injury was glass, 149 cases(64.8%) and the next on was knife, 37 cases(16%). 4. Injuries in the night were more than daytime. 5. Injuries in the summer were more than winter.

A pathologic fracture is a fracture of a bone with preexisting structural weakness. When considering the local treatment of pathologic fractures, those resulting from disorders which cause a generalized weakness of the whole or part of the skeleton can be largely treated conservatively. And those because of localized bone destruction or weakness often require operative treatment. For ten years from 1973 to 1983, we observed and analysed 26 cases of pathologic fractures, excluding those due to osteoporosis. The results were as follows: 1. The age distribution showed an even pattern, and the male to female ratio was 58% (15 Males): 42% (11 Females). 2. The underlying etiologies were infection in 6 cases (23%), disturbance in skeletal development in 7 cases (27%), benign tumorous lesion in 10 cases (38%) and malignant tumorous lesion in 3 cases (12%). 3. The most common site was femur, 54% (14 cases). 4. Previous treatment was carried on 38% (10 cases). 5. Of the 26 cases, conservative treatment was done in 4 cases (15%) and surgical treatment was done in 22 cases (85%).

Branch retinal vein occlusion(BRVO) is the most frequent entity of retinal vascular abnormality following diabetic retinopathy; a review of diagnosis for all our new outpatients verifies this, Sudden loss of visual acuity occur in the vast majority of BRVO patients. Other complications are macular edema, capillary nonperfusion, neovascularization, vitreous hemorrhage and so on. We did a clinical analysis of 71 patients with BRVO(71 eyes), who were considered to be treated with laser photocoagulation to prevent vitreous hemorrhage. We confirmed the fact that laser photocoagulation could prevent vitreous hemorrhage to a significant degree, but we were unable to demonstrate any statistical correlation between the occurrence of vitreous hemorrhage and the time of laser photocoagulation.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.

10.A Case of Ectopic Orbital Meningioma.
Journal of the Korean Ophthalmological Society 1988;29(3):471-476
A 37 year-old male was suffered from proptosis without visual loss for 5 months. The orbit CT scan showed an eyeball-sized, extraconal, intraorbital soft tissue mass. The mass was removed by modified Kronlein operation and was diagnosed as the transitional type of meningioma by light microscopic and electron microscopic findings. After, surgery, there is no recurrence after 6 months.
