Congenital kyphoscoliosis is an abnormal curvature of spine that is due to presence of vertebral anomalies which cause an imbalance in the longitudinal growth of the spine. Congenital kyphoscoliosis is often rigid and its correction can be difficult. It is often resistant to conservative treatment and more patients require surgical treatment than those with idiopathic curvature. The indication for the conservative treatment with Milwaukee brace is much limited. Largely Milwaukee brace is a delaying tactic to correct the spinal curvature until its growth is further advanced and it is more amenable for fusion. This paper was aimed to review our experience with 49 patients with congenital scoliosis, kyphosis and kyphoscoliosis who were treated surgically with various methods of preoperative correction, from Jan. 1968 to Dec. 1983, in special reference to new classification, proposed for common application to both kyphosis and scoliosis, and following results were obtained. 1.The average age when scoliosis was observed was 6.9 years, but the average age of surgery was deferred until 15.2 years. 2. The distribution of curve pattems were 1 cervicothoracic, 24 thoracic, 12 thoracolumbar, 7 lumbar and 1 lumbosacral curve in 45 scoliotic curves and 13 thoracic, 13 thoracolumbar and 4 lumbar curves in 30 kyphotic curves. The average degrees of deformity were most severe in thoracolumbar curves both in kyphosis and scoliosis. 3. The new morphological classification, which could be applicable to both kyphosis and scoliosis, was proposed. The type of unsegmented bar with contralateral hemivertebra was most common both in kyphosis and scoliosis. 4. Preoperative average degrees of scoliosis was 58.7 degrees and final correction was 20.6 degrees (35.1%) with loss of comection of 3.7 degrees (6.3%). Preoperative average degrees of kyphosis was 63.7 degrees and final correction was 20.1 degrees (42.5%) with loss of correction of 7.0 degrees (11.0%). 5. The surgical method with anterior and posterior fusion was the best treatment of severe kyphoscoliossis, in the aspect of final correction and loss of correction. 6. The lumbar curve was most amenable to treatment with the best final correction and the least loss of correction.

This report describes the pathologic features of 17 cases of Castleman's disease, examined at the Department of Pathology, Seoul National University Hospital during a period from 1973 to 1989. The lesions in 12 cases were hyaline-vascular type and the remainders plasma cell type. The pathologic features favoring the plasma cell type over the hyaline vascular type included a sufficient number to large-sized follicles. However, a histologic overlapping between two types was present. In the hyaline vascular type the age of the patients ranged from 7 to 76 years and they appeared to be no particular sex predominence. The majority of the lesions occurred in the neck and within the chest. Almost all cases presented with a solitary mass except three cases. Neither conventional symptoms nor systemic manifestations were associated. The plasma cell type was characterized by presentation of constitutional symptoms, involvement of intra abdominal and inguinal lymphnodes, in association with unusual clinicopathologic features including IgA nephropathy, diabetes mellitus, systemic progressive sclerosis, peripheral neuropathy, and anemia. Immunohistochemical study was performed in three cases of the plasma cell type. Two cases revealed poly-clonal plasma cell infiltration. In a patient with IgA nephropathy, however, serum IgA was increase and a strong immunoreactivity to IgA heavy chain was found. Another case, associated with systemic progressive sclerosis and neuropathy, revealed monoclonal plasma cell infiltration (IgG and lambda light chain). The above results support a possibility that in some of the plasma cell type an altered immune mechanism is involved in its pathogenesis.

Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

Cancer is considered to occur through abnormal growth and differentiation processes, in which oncogenes and tumor suppressor genes are deeply related. Cellular responses to DNA-damaging agents are believed to be critical determinants of human tumorigenesis. Cell cycle arrests and DNA repair following DNA damage require the coordination of multiple gene products that, as a whole, serve to maintain the integrity of the genome. Within the cell cycle, both G1-S and G2-M phase transitions are under constant surveillance by checkpoint genes for the protection of cells from either exogenous or endogenous DNA-damaging agents. p53 tumor suppressor gene mediates cell cycle perturbations in response to DNA damage, and play a role in cell death, genetic stability, and cancer susceptibility. Recently, gene therapy with p53 tumor suppressor gene is expected as a new effective therapeutic strategy in many kinds of cancer. By using retroviral vector system, we transduced p53 tumor suppressor gene into human osteosarcoma cells, and analysed its growth suppression and apoptosis inducing effects. Combined effects of p53 gene therapy with chemotherapeutic agent or radiation were also analysed. Titer of ecotrophic p53 retrovirus was 5.0x10/ml, and that of amphotrophic p53 retrovirus was 2.0x10/ml when NIH3T3 cells were used as target cells. Human osteosarcoma cells infected with amphotrophic p53 retroviruses showed increased p21waf1 gene expression, which acts as a major cyclin-dependent kinase inhibitor in DNA damage responses. In normal DMEM media, human skin fibroblasts infected with amphotrophic p53wt retroviruses showed very slow growing (1.7 fold increase in doubling time) and very low saturation density (50% decrease in cell density). In media containing chemotherapeutic agent, human osteosarcoma cells infected with p53wt retroviruses died rapidly; 75% of them died within 4 days and all of them died within 10 days of incubation with chemotherapeutic agent. Their DNAs were extracted and electrophoresed in agarose gel, and we identified DNA ladders characteristic of apoptotic cell death. When human osteosarcoma cells infected with p53 retroviruses were irradiated with ultraviolet light, more than 95% of cancer cells died within 1 day; whereas mock infected cells showed only less than 5% of cell death. These findings suggest that retroviral vector mediated p53 tumor suppressor gene transfer into cancer cells can suppress tumor cell growth and decrease tumor cell density effectively. These findings also suggest that effective induction of tumor cell apoptosis can be obtained when p53 gene therapy is used in combination with chemotherapy or radiotherapy.

This review-article is aimed at shedding a light upon the nature of age-associated changes in the human skeletal system. When the anatomical, physiological and biochemical consequences of bone aging are considered together with the hardening, drying and the diminished repair capabilities of the elderly, it can be seen that fractures assume greater importance as a clinical problem in the geriatric population. Older people start out with a deficit of cortical bone, making them more fracture prone and once fractures occur, the necessary treatments (immobilization, use of casts, etc.) accelerate the rate of bone loss. In addition, aged individuals stand a higher risk for complications of the hospital and enforced bed rest that may ensue. The problems resulting from bone loss in the elderly may be partially alleviated by providing adequate health service support which should include consideration of the following points : 1. Age, sex and general health status ; 2. Habits and inclinations towards physical activities ; 3. Nutritional and endocrine background ; 4. Presence of any specific bone diseases, including osteoporosis, osteoarthritis, osteomalacia and ankylosis ; 5. Psychosocial adaptability and other behavioral elements.

A new case of the recently experienced intraocular cysticercosis associated with multiple skin lesions (subcutaneous nodules) is presented. Clinical picture of this case was characteristic with bizarre shape retinal hemorrhage, and clinical diagnosis was possible by the fluorescein angiography of fundus. Trans-scleral extraction of the subretinal cysticercus was performed successfully without rupture of a cyst-capsule through the infero-temporal quadrant of sclera near to the equator of right eye. Diagnosis of ocular cysticercosis was confirmed by histo-parasitological examination on the extracted cyst of 5 x 7 mm in size. Oral medication is generally not amenable treatment for the intraocular cysticercosis, and less traumatic surgical removal is the only effective method for the improvement of visual function or preservation of the eye itself. The immense review of literatures on the ocular cysticercosis including the subretinal invas ion was attempted.

During the reproductive period, human endometrium undergoes a pattern of cyclic change. Human endometrium undergoes a complex pattern of proliferation, secretory activity, and menstruation over an approximately 28 days period. Proliferative activity is highest during late proliferative phase under influence of estrogen, and minimal activity in the late secretory and menstrual phase. To study a possible change of telomerase activity during menstrual cycle, telomerase activities in normal and hormone treated endometrium were tested using telomerase repeat amplification protocol(TRAP) assay. Telomerase activities were detected in 9 of 10 proliferative endometrium(90%), and maximal activity was shown in late proliferative phase. Only 3 of 10 secretory endometrium(30%) revealed weak activity. However telomerase activity was not detected in menstrual phase endometrium(N 2) and senile endometrium(N=3). Four of tamoxifen treated endometrium(N 4) and 1 of provera treated endometrium(N 3) Levels of telomerase activity of treated endometrium(N 4) and late proliferative endometrium(N 6) were as high as them of detected in endometrial cancer and hyperplasia. Above findings reveal that telomerase activity of endometrium is changed according to menstrual cycle, And the level of telomerase activity is related to proliferative activity of endometrium that is dependent on the status of female sex steroid hormone and tamoxifen treatment.

9.Effects of Community-based Comprehensive Fall Prevention Program on Muscle Strength, Postural Balance and Fall Efficacy in Elderly People.
Journal of Korean Academy of Nursing 2014;44(6):697-707
PURPOSE: The purposes of this study was to develop a comprehensive community-based fall prevention program and to test the effects of the program on the muscle strength, postural balance and fall efficacy for elderly people. METHODS: The design of this study was a nonequivalent control group pretest-posttest design. There were 28 participants in the experimental group and 29 in the control group. The program consisted of balance exercises, elastic resistance exercises and prevention education. The program was provided five times a week for 8 weeks and each session lasted 90 minutes. Data were analyzed using chi2-test, independent t-test and paired t-test using the SPSS program. RESULTS: Muscle strength of the lower extremities, postural balance and fall efficacy scores significantly improved in the experimental group compared to the control group. CONCLUSION: These results suggest that this program can improve lower extremity muscle strength, postural balance and fall efficacy in elders. Therefore, this program is recommended for use in fall prevention programs for elders living in the community.

PURPOSE: This study was aimed to evaluate the recurrence rate of a giant cell tumor (GCT) of the bone. MATERIALS AND METHODS: The medical records of fifty four patients who were diagnosed with a giant cell tumor of the bone between March 1980 and December 2008 were analysed retrospectively. Among 54 patients, 27 were men, remaining 27 were women with the mean age of 33.1 years (range, 13-67 years). The mean duration of follow-up was 67.1 months. RESULTS: Twenty-one patients (38.9%) had a local recurrence. The mean time to recurrence was 21.5 months (range, 2-59 months). The local recurrence rate of the upper extremities was higher than that of lower extremities. According to Campanacci classification, patients with a grade I diseae had lower recurrence rate than those with grade II or III disease. There was no significant differences in the recurrence rates based on cryotherapy, the filling of bone cement or bone grafts and surgical margin. CONCLUSION: To prevent local recurrence of GCT of bone, curettage of the tumor and elimination of the remaining cells are more important than adjuvant therapy.
