Experiences of 26 cases of electrical bone stimulation on normal adult rabbits was documented in this paper. The cathodic electrode was introduced longitudinally into the medullary cavity of the proximal tibia and the anodic electrode was introduced transversely in the distal femur of the same side. The contralateral tibia was used as the control, of which the Teflon coated Kirschner wire was introduced longitudinally into the medullary cavity. 10uA of direct current was passed continuously through the fixed wires between the proximal tibia and distal femur. At the second, fourth and sixth week, random bone scan with 99m-Tc was performed and the animals were sacrificed. The specimen X-rays of the tibia and femur were taken and the specimens were prepared for the microscopic study. The followings are obtained from this experimental study. 1. The rate of new bone formation is 69.2% in the stimulated group and 7.7% in the control group. There were also fibrosis and cartilage formation as well as the new bone formation. The fibrosis and cartrilage formation are observed only in the electrically stimulated side and their occurances are 69.2% and 11.1% respectively. So The new bone formation and fibrosis are definitely increased in the bones of the cathodic electrical stimulation than those of the control side. 2. The intramembraneous ossification is the predominent feature of this electrically stimulated new bone formation. 3. Bone and soft tissue necrosis was the main microscopic feature in the anode side. 4. Since new bone, fibrous tissue and sometimes new cartilage were observed in this study, it seems that the cathodic electrical stimulation is not specific for the new bone formation, but induce crude tissues such as bone, cartilage, fibrous tissue or vessels. Furthermore, it can be postulated that the 10uA electrical stimulation is only one of the best electrical environment for the formation of the crude tissues, especially for bone and fibrous tissue.

Giant cell tumor of tendon sheath(GCTTS) is a benign mesenchymal lesion composed of cytologically bland mononuclear cells admixed with multinucleated giant cells. Our report describes the clinical and pathologic features of a 36-year-old female's tumor with a two years history over the lateral side of the left little finger, Especially, we could observe the characteristic thre types of cells in an electromicroscopic study, histiocyte-like cells, fibroblast-like cells and multinucleated giant cells. In lmmunohistochemical studies, we demonstrated that the tumor cells of GCTTS exhibit a phenotype consistent with histiocyte differentiated to Langerhan's cell.

Fractures of the neck of the femur have always presented great challenges to orthopedic surgeons and still remain as one of the unsolved fracture as far as treatment and results are concerned. With life expectancy increasing with each decade, becoming more and more patients suffering from femoral neck fractures and their sequelae. The objoct of this study is to observe the relationship between the clinical results and the degree of displacement of fracture, degree of osteoporosis and duration between injury and operation in femoral neck fractures treated with multiple pin fixation. The author clinically analyzed 56 patients of the femoral neck fractures treated with closed reduction and multiple Knowles pinning followed by more than 1 year at Korea University Hospital from January 1986 to December 1991. There were 20 male and 36 female. The age of patients were ranged from 32 to 88 years(average:65.1 years) and most commonly occurred in 7th decade (23cases,41%). The most common cause was slip down(44 cases;79%). The most common type of fracture was stage III (48%) following to Gardens classification. The obtained results were as follows; 1. Union occurred in 49 cases(88%). 2. Among fifty-six cases, five cases(9%) of avascular necrosis, two cases(4%) Of non-union, two cases(4%) of malunion and one case of posttraumatic arthritis were occurred. 3. The functional results by Lunceford criteria were excellent in 30 cases(53% ), good in 13 cases(23%), fair in 5 cases(10%) and poor in 8 cases(14%). 4. Unsatisfactory results were noted in Garden stage II or IV, osteoporosis below Singh index 3 and delayed treatment over 1 week. Above results suggest that multiple Knowles pinning in femoral neck fractures offers high union rate and low complication rate, and so is also one of salvaging method of femoral head.

A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

BACKGROUND: With the rapid growth of the elderly population, osteoporosis has become a major health problem worldwide. Although health knowledge and self-efficacy are important assets to facilitate healthy behaviors and disease prevention, such information as it relates to individuals and their bone health is limited. The purpose of this study was to assess the levels of knowledge, self-efficacy, and health behaviors on promoting bone health in middle-aged Korean women. METHODS: This is a cross-sectional survey study. A convenience sampling of middle-aged women (> or =40 years) was done at a community health center in Korea. Bone mineral density was measured by dual energy X-ray absorptiometry with the DEXXUM T. The level of knowledge was measured with the Knowledge of Osteoporosis Scale, and self-efficacy with the Osteoporosis Self-efficacy Scale. A questionnaire for bone health behaviors was developed for this study. Collected data were analyzed through descriptive methods, independent t-test, analysis of variance, and Pearson's correlation analysis. RESULTS: A total of 150 middle-aged women whose mean age was 59.8+/-11.5 years participated in the study. Most (74%) were menopausal. Less than one-quarter of participants (22.7%) had osteoporosis and less than half (42%) had osteopenia based on the T-score at the left femur neck site. Level of knowledge (mean score, 10.35) and self-efficacy (mean score, 47.67) ranged from low to moderate. Intake of calcium and vitamin D-rich foods was insufficient in our subjects. Bone health behaviors had significant positive relationships with knowledge (r=0.22, P=0.008) and self-efficacy (r=0.29, P<0.001) on promoting bone health. CONCLUSIONS: These results indicate that educational interventions are needed to enhance knowledge and confidence and to encourage middle-aged women to engage in bone health behaviors.

Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two canals and from unilateral to bilateral involvement during the reposition maneuver. This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.

Ectopic pregnancy refers to gestation in which the fertilized ovum implants on any other tissure than tbe mucus membrane lining the uterine cavity. Cornual (intertitial) pegnancy is a relatively uncommon but potentially catastrophic form of ectopic pregnancy, defined as implantation in the intramural portion of a fallopian tube. A hydatidiform mole usually occupies the uterine cavity but it's occurrence in the uterine tube is extremely rare. Only a few cases of primary hydatidifm mole of the tube have been reported. We experienced a case of ectopic hydatidiform mole in the uterine cornua and so present it with brief review of literatures.
