Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

The proposed factors that affect the prognosis of osteosarcoma are the patient's age, site and size of the primary lesion, pathologic features(type and grade), duration of symptoms, spread of disease (local or regional extension, distant metastasis) at diagnosis, the patient's sex, serum alkaline phos- phatase(ALP) and lactic dehydrogenase(LDH) levels, chromosomal number or DNA index, response to initial chemotherapy, location of the lesion on the bone, presence or absence of pathologic fracture, and mode of therapy. The purpose of this study is to analyze the factors that affect the 5-year survival rates of osteosarcoma. Total 25 patients were included in this study who had treated form Jan. 1988 to Apr. 1994. The overall 5-year survival rate of 25 patients was 65.43%, and the 5-year survival rates were sig- nificantly higher(P < 0.1) in the groups in which limb salvage operation with neoadjuvant chemothera- py were performed(66.67%), with longer duration of symptoms(>2 months; 83.33%), with lower serum level of LDH( < 300 U/L; 100%), and with smaller mass size( < 10cm; 72.92%). However there were no significant differences in the 5-year survival rates according to age and sex of the patients. We also suggest that the better prognosis will be observed in the patients with the favorable radiologic response to the preoperative chemotherapy.

4.The Expressions of Androgen Receptors and Estrogen Receptors in Bald and Non-bald Area of Androgenic Alopecia.
Korean Journal of Dermatology 2002;40(12):1487-1492
BACKGROUND: Androgenic alopecia, commonly known in men as male pattern baldness is the gradual balding of the scalp in response to androgens in genetically predisposed individuals. Androgens can gradually transform large scalp hair follicles to smaller vellus ones, causing balding. The mechanisms involved are unclear, although androgens are believed to act on the epithelial hair follicle via the mesenchymal derived dermal papilla. During pregnancy, hair growth is increased, as estrogen appears to prolong the anagen phase, and postpartum hair loss may be related to a rapid decrease in estrogen. OBJECTIVE: The aim of the present study was to evaluate the difference of the expressions of androgen receptors(AR) and estrogen receptors(ER) by monoclonal antibodies in biopsy specimens between bald area and non-bald area. METHODS: Immunohistochemical analysis of AR and ER receptor were preformed on the paraffine-embedded tissue sections of bald area and non-bald area in 6 cases of androgenic alopecia using anti-AR and anti-ER monoclonal antibodies with avidin-biotin peroxidase complex procedure. RESULTS: The results were that androgen receptors were higher level in bald area and estrogen receptors showed no difference between bald and non-bald area. CONCLUSION: This study supports that locally increased androgen activities may be related with hair loss in androgenic alopecia and estrogens have less relationship in the pathogenesis of androgenic alopecia.

5.Status of Enterobius vermicularis Iifection in primary school children, Yongyang-Kun, Kyongbuk Province.
The Korean Journal of Parasitology 1984;22(1):138-140
An epidemiological study was undertaken to estimate the prevalence of Enterobius vermicularis infection among the primary (and infant) school children in Yongyang-gun, Kyongsangbuk-do. During the period from 2 to 14 December 1983, a total of 2,227 school children in 13 schools were examined one time by means of scotch-tape anal swab technique with a simple questionaire study on perianal itching, enuresis and school record. The results are as follows:The overall egg positive rate was 64.1 percent and the rate ranged from 46.6 to 86.7 percent by schools. The egg positive rates of boys and girls were 60.5 and 68.0 percent respectively and the difference was statistically significant (p<0.005). There was noted a tendency of decrease in prevalence by increase of the age of children. It was revealed that perianal itching and school record were significantly correlated with E. vermicularis infection (p<0.05) while not in case of enuresis (p>0. l).

BACKGROUND/AIMS: Gastric carcinoma is the most common malignant neoplasm in Korea and is known to be associated with intestinal metaplasia (IM) of gastric epithelium, of which type III IM is suggested to play a special role in the carcinogenesis. This study is to evaluate the subtypes of IM and to measure each subtype in chronic gastritis. Methods: From October 1997 to September 1999, 321 patients with endoscopic chronic gastritis were evaluated the grade of chronic gastritis and IM by histologic and histochemical stain. RESULTS: Chronic inflammation and IM were remarkably severe in men and Helicobacter pylori (H. pylori) positivity was 69.4% in men and 65.2% in women. The frequency of IM was 50.1%, of which 65.4% was in men and 34.6% in women. The frequency of IM subtypes was 43.2%, 11.7% and 45.1% for type I, II and III respectively. Sixty percent of IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. The frequency of type III IM was 61.6% in men and 38.4% in women. Sixty one percent of type III IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. Interestingly, fifty three percent of type III IM was noted in men more than 40 years of age. The prevalence of H. pylori infection in type III IM was similar to in type I and II. The glandular atrophy in type III IM was remarkably severe than that in type I and II. Conclusions: The results of this study show that the proportion of type III IM in chronic gastiritis is remarkably high in Korean and age and sex distribution is similar to that of gastric carcinoma.

7.A Case of Multiple Eyelid Trichilemmoma Associated with Cowden Syndrome.
Journal of the Korean Ophthalmological Society 2013;54(5):803-807
PURPOSE: To report a case of multiple eyelid trichilemmomas associated with Cowden syndrome. CASE SUMMARY: A 27-year-old woman presented with multiple upper and lower eyelid skin masses that developed over several years. The masses were as large as whitish millet, and were around the upper and lower eyelid margin and the face. The patient had previously undergone subtotal thyroidectomy for a thyroid mass and a mass excision for extremity hemangioma. Excisional biopsy was performed for the diagnosis, and trichilemmoma was diagnosed based on histopathologic examination. Consequently, multiple trichilemmoma associated with Cowden syndrome was diagnosed, and breast evaluations for existence of further masses were recommended. On breast examinations, intraductal papilloma and fibroadenoma were detected. CONCLUSIONS: The trichilemmoma was a hair-follicle benign tumor that also appeared on the skin around the eyelid. If multiple trichilemmoma is diagnosed, an association with Cowden syndrome should be considered as well as presence of masses in other organs.

Recently, we have encountered an increasing number of patients who have obtained topical steroids to self-treat various dermatosis. Tinea incognito has been used to describe a dermatophyte infection modified by corticosteroid treatment. Lesions are often atypical appearing and the diagnosis can be delayed or missed. We report a case of tinea incognito with ill-defined erythematous patch and nodules on the right upper eyelid and taken intermittently application with corticosteroid ointment over a period of l year. Mycologic studies including KOH mount and fungus culture were positive for hyphae and colonies of Trichophyton mentagrophytes. The lesion was treated with of itraconazole and cured 3 weeks later.

Localized primary cutaneous amyloidosis consists of three types: nodular, macular, and lichenoid amyloidosis. Lichen amyloidosis is characterized by the appearance of paroxysmally itchy lichenoid papules on the shins. Although the origin of the amyloid is controversial and can not provide any definite answer, some of amyloid substances can be derived from epidermal cells and others from degenerative collagen fibers. We suggested the origin of amyloid in our cases as epidermal keratinocyte and collagen degenerations. Because degeneration of basal keratinocyte is observed on electron microscopy and degeneration of collagen is in H&E and Masson's trichrome stain although amyloid materials are negatively stained against pankeratin antibody and collagen antibody. The skin lesion was improved after triamcinolone intralesional injections which reduce collagen synthesis. We report two cases of lichen amyloidosis which stained negatively for antikeratin antibodies and improved with triamcinolone intralesional injection.
