Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

Male Breast cancer is an uncommon disease with an incidence of I per cent of all breast cancers. Male breast cancer usually appears as a small mass with well-defined contour which is eccentrically located in relation to the nipple on mammogram. We report a case of breast cancer in a 51-year-old man with mammographic appearance of large hyperdense mass with nipple inversion and axillary lymphadenopathy, gray-scale sonographic finding of homogeneous solid mass and mu Itiple tumor vessels with in the mass on color Doppler ultrasound.

Thanatophoric dysplasia is the most common lethal congenital chondrodysplasia with characteristic features of narrow thorax, short rib, severe platyspondyly, short bowed limbs and skull deformity, etc. It is not a hereditary disorder and there is usually no family history of dysplasia. We experienced a case of thanatophoric dysplasia at 38 weeks of gestation with antenatal sonographic and abdominal radiographic findings of small thorax, short bowed extremities with surrounding thickened soft tissues and marked platyspondyly. Soon atter delivery, the baby died and post-mortem radiographs showed the characteristic findings of thanatophoric dysplasia.

Urinary protein per se causes renal tubular injury and stimulates immunologic reaction. The extent of proximal tubular injury can be estimated by measuring the amount of 24 hours urinary beta2-microglobulin (U beta2-MG). The aim of this study was whether U beta2-MG level could predict the response to the initial steroid treatment for the patients with minimal change nephrotic syndrome (MCNS). We analyzed 58 adult patients (33 M, 25 F), aged 33+/-15 years (range 16-76), with biopsy-proven MCNS treated with 40 to 60mg of oral prednisolone daily up to 16 weeks. The responsiveness (44 cases) inculded complete and partial remission or steroid resistance (14 cases). No difference was found between the steroid responsive and resistant group with regard to age, BUN, serum creatinine, albumin, cholesterol, and urinary protein. The levels of U beta2- MG (microgram/g creatinine) were 250808+/-478917 and 1648+/-2386 in resistan ia Kwang-Yul Chang, et al.:Prediction of Steroid Responsiveness in Adult Minimal Change Nephrotic. Syndrome Using Urinary beta2-Microglobulint group and responsive group, respectively (P<0.05). The cut off value was 400microgram/ g creatinine with 78% of sensitivity and 48% of specificity. The likelihood ratio for the resistance was 2.5 to 2.8 with the U beta2-MG levels over 400 ug/g creatinine and was 0.2 to 0.3 below that value. Multivariate analysis confirmed that higher U beta2- MG level was associated with a lower likelihood of steroid responsiveness, independent of age, sex, creatinine, serum protein, and urinary protein. This study showed that the pretreatment U beta2- MG level may be used to identify subgroup of patients with MCNS who are more likely to be responsive to initial steroid treatment.

OBJECTIVE: The objective of the study was to estimate socioeconomic burden of polycystic ovary syndrome (PCOS) during the reproductive life span using current definitions and prevalence or incidence data. METHODS: Questionnaires were given to 8,588 reproductive women reviewed at Ewha Womans University Mokdong hospital. The PCOS affected approximately 10.4% of reproductive-aged women (11 million women in Korea, prevalence rate according to 1990 National Institutes of Health PCOS diagnosis criteria). We tied general societal cost data for the different health consequences to reproductive-age PCOS costs, using prevalence data. RESULTS: We estimated the mean annual cost of the initial evaluation to be 76 hundred million won, that of hormonally treating menstrual dysfunction, providing infertility care, diagnosis/treatment of endometrial hyperplasia, GDM, type 2 DM, and hypertension to be 280 billion won. The total annual socioeconomic cost of evaluating and providing care to reproductive-aged PCOS women in Korea is 350 billion won. CONCLUSION: Because the cost of the diagnostic evaluation accounted for a relatively minor part of the total socioeconomic costs, more widespread screening for PCOS appears be a cost-effective strategy, leading to earlier diagnosis and intervention and possibly the amelioration and prevention of serious sequelae.

Authors analysed and present chest X-ray findings of serologically proven leptospirosis from Seoul NationalUniversity Hospital, either admitted or referred for serological verification, during recent 2 years. Radiologicalfindings were correlated with the lung specimen finding of experimentally induced leptospirosis in guinea pig. Theresults are as follows: 1. 24 cases(56%) showed positive X-ray findings. 2. Predominent radiological patterns ofinvolved lung were tiny dot, small nodule, rosette density in 11 cases, massive confluent consolidation in 4cases, and diffuse ill-defined veilly increased density in 9 cases. 3. Distribution of pulmonary lesions werebilateral (100%), non-lobar, non-segmental(95%), and there were conspicuous tendency of peripheral lungpredominence. 4. Extrapulmonary manifestation, such as pleural effusion or cardiomegaly was rare. 5. Pulmonarylesions resolved completely usually 5 to 10 days after their appearance. 6. From the gross and microscopicfindings of serially sacrified guinea pig's lung and a case of autopsy, authors conlcuded that fine dot-likedensity in chest X-ray was due to petechial hemorrhage in intraalveolar space at initial stage, growing up toressette density or confluent consolidation as the petechia extends to surrounding lung forming purpura andcoalescent hemorrhage.

A retrospective analysis of CT and MR findings was performed in five patients with histologically proved chordoma including one with chondroid chordoma. All tumors were mostly isodense to gray matter on unenhanced CT, and the single intensities were iso or low and high on T1 and T2-wgighted MR iages, respectively. The tumors had an increase in their density on enhanced CT and MR in four patients, but a chondroid chordoma was poorly enhanced after injection of contrast medicum on CT. Four tumors contained calcifications in CT images and two lesions showed hemorrhage in MR images. Cavernous sinus was involved in all patients, and brain stem and basilar artery were compressed by the tumors in three cases. Pituitary gland was only displaced upward in three patients. Clivus was destroyed in all cases, and sella turcica and sphenoid bone were involved in three patients. CT is better than MR in demonstrating calcifications and bone destruction. In defining the extension of tumor, MR appears to be superior to CT in evaluation of the relationship between the tumor and the surrounding structures.

OBJECTIVES: The health examination survey was conducted in order to estimate the prevalence of major chronic diseases in a community. METHODS: A multi-stage stratified probability sample of 1,656 persons, aged from 20 to 69 years, was drawn out from Kuri City. All sampled persons were personally informed of the purpose, content and procedures of the survey and mobile examination center was run between 6 AM and 9 PM for the convenience of the participants. RESULTS: 854 persons (339 males and 515 females) completed this survey with a response rate of 53.4%. Prevalent diseases in male were hypertension(19.0%), HBs Ag carrier(9.8%), impaired glucose tolerance(8.7%), diabetes mellitus(6.3%), hypercholesterolemia(3.4%), anemia(2.7%) and degenerative arthritis(2.6%) in order of prevalence rate. Prevalent diseases in female were osteoporosis(22.5%), impaired glucose tolerance(17.3%), anemia(12.8%), hypertension(12.4%), degenerative arthritis (6.6%), HBs Ag carrier(5.8%), diabetes mellitus(5.4%) and hypercholesterolemia(3.5%) in order of prevalence rate. CONCLUSIONS: This results suggest that hypertension was most prevalent in adult male whereas diabetes mellitus including IGT, osteoporosis were most prevalent in adult female, in Kuri City.

PURPOSE: The purpose of this study is to evaluate the characteristics of parotid gland tumors to help in the differentiation between benign and malignant lesions. MATERIAL AND METHODS: The CT findings of 22 patients with surgically proven parotid gland tumors were reviewed. Analysis was focused on the density and margin characteristics of the tumors, and the relationahip between the tumor and surrounding structures. RESULTS: Those tumors were pleomorphic adenoma (n=8), Warthin's tumor (n=5), basal cell adenoma (n=l), lipoma (n=l), dermold cyst (n=l), adenold cystic carcinoma (n=2), mucoepidermoid carcinoma (n=l), epidermold carcinoma (n=l), and carcinoma in pleomorphic adenoma (n=l). Most of benign and malignant tumors were heterogeneous in denstiy on contrast enhanced CT scans. In 5 of 6 malignant cases, the tumors had irregular or ill-defined margin and a tendancy to involve or cross the superficial layer of deep cervical fascia with obliteration of subcutaneous fat. Two malignant tumors invaded surrounding structures. CONCLUSION: Although the heterogeneous density of tumor is not a specific finding for malignancy at CT, following findings, such as, irregular or blurred margin of the lesion, the involvement of fascial plane, and the infiltration of surrounding structures may suggest the possibility of malignant parotid tumor.

PURPOSE: Spontaneous subarachnoid hemorrhage(S-SAH) is a relatively rare disease with good clinical course and prognosis. The purpose of this study is to evaluate the cisternal blood distribution on CT in patient with S-SAH. MATERIALS AND METHODS: Out of 406 patients with subarachnoid hemorrhage on brain CT scan, 11 patients confirmed to be S-SAH by angiography and clinical follow-up were examined. We analysed the CT findings of these 11 cases retrospectively. RESULTS: Five patients had only perimesencephalic distribution of hemorrhage:the prepontine, the interped- uncular, and the suprasellar cisterns were involved in 4 cases each, the basal sylvian cistern in 3 cases, and the ambient cistern in 2 cases. The quadrigeminal and a portion of the lateral sylvians were also involved in 1 case each. Six patients revealed cisternal hemorrhage extending beyond the perimesencephalic cistern into the ventricles, cortical sulci, and lateral sylvian fissure. Intraventricular hemorrhage was noted in 3 cases of these 6 patients. CONCLUSION: Our study suggests that uncomplicated clinical course and normal anglographic finding are more important than CT distribution of cisternal hemorrhage in diagnosing S-SAH.
