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.

The periodontal health has been evaluated clinically by various epidemiological indices, and in researches by measurement of gingival crevicular fluid. Laser Doppler flowmetry is a reliable and objective method that allows immediate measurement of erythrocyte flux in approximately one cubic mm of the capillary bed without disturbing the tissues. The purpose of the present study was to determine whether human gingival blood flow was different according to measuring area, measuring time, and sex or not. Forty volunteers with good general and periodontal health, aged early twenties and unmarried, were selected. Laser Doppler flowmetry(floLAB(R), Moor Instruments Ltd., England) was applied to measure the gingival blood flow of marginal gingiva, interdental papilla, attached gingiva and alveolar mucosa. The blood flow of interdental papilla was measured at 9-10 AM, 1-2 PM, and 5-6 PM. The difference of blood flow according to measuring area and measuring time was statistically analyzed by one way ANOVA and Dunkan test, and the difference of blood flow between men and women was statistically analyzed by t-test. (1) Mean blood flow was significantly higher in alveolar mucosa than in the gingiva(p<0.05), and there was no significant difference in blood flow between marginal gingiva and interdental papilla(p>0.1). (2) Mean blood flow was significantly higher at 5-6 PM than at 9-10 AM and 1-2 PM(p<0.05). But there was no significant difference in gingival blood flow between 9-10 AM and 1-2 PM(p>0.1). (3) There was no significant difference in gingival blood flow between men and women(p>0.1). The above results suggest that the measurment of gingival blood flow using laser Doppler flowmetry may be clinically applicable to early determination of gingival inflammation and evaluation of healing status, but further studies are necessary to standardize and simplify the measuring procedure.

There are diverse surgical methods for treating large bladder stones, such as transurethral cystolithotripsy (TUCL), percutaneous suprapubic cystolithotripsy (PCCL), open surgery, and laparoscopic methods. We report here a case of two large bladder stones treated by using a combined surgical method of a laparoscopic approach and direct visual lithotripsy.

Bacillus species are aerobic, gram-positive, spore forming rods that are widely distributed in soil, dust, stream, and other environmental sources and are regarded as natural organism. But certain species of the genus Bacillus, most notably B.cereus, which is associated with food-borne illness, occasionally have been implicated in the occurrence of fatal illness and complication in a compromised host. We roport a case of pneumonia and bacteremia caused by B.cereus in an 81 year-old man, who had no obvious immunologic compromise. The condition was treated with combination of roxithromycin and gentamicin.
