1.Atypical Ductal Epithelial Hyperplasia in Breast: Marnrnographic, Sonographic, and MR Findings.
Journal of the Korean Radiological Society 1994;31(3):559-566
PURPOSE: To document the radiologic characteristic findings of atypical ductal epithelial hyperplasia, we analyzed film mammographic, ultrasonographic, and MRI findings of our cases. MATERIALS AND METHODS: We analyzed 23 cases of surgically proven ADH, excluding carcinoma in ipsilateral breast. Presence and pattern of neodensity, microcalcification, and architectural distortion were reviewed on mammography. Echo pattern and ductal parenchymal morphology were analyzed on ultrasonography, and enhancement speed and pattern analysis were performed on MRI. RESULTS: On film mammography, ADH showed tendency of neodensity(10 of 23 cases), m icrocalcification(11 of 23 cases), with less parenchymal distortion of surrounding structures(7 of 23 cases). On ultrasonography, ADH was demonstrated as inhomogenous to intermediate echoic nodule(16 of 20 cases) with ragged border(19 of 20 cases), however, its boundary was thin or nearly absent(16 of 20 cases), and showed smooth ductal echography(11 of 20 cases). Gd-DTPA contrast dynamic MR study showed relatively slow and less enhancement in 4 out of 5 cases, with progressive inclination of the speed curve of enhancement in later period of dynamic study. CONCLUSION: Multimodality image approach is needed for better evaluation of ADH, however, excisional biopsy is recommended for confirmative diagnosis and proper treatement.

In order to discover difference that may exist in quantity of medical care services, length of stay and hospital changes between insured and non-insured patients, records for primary Cesarean section patients discharged between July 1978 and June 1980 from a university hospital were examined. In addition, Cesarean section rates among the total deliveries for a two-year period between the groups were studied. The results showed that volume of services was greater and length of stay was longer among the insured, however, charges were higher among the non-insured. Cesarean section rates were statistically significantly different between insured and non-insured patients for every age group except the group of 35 or more.

Rickets is a syndrome, characterised pathophysiologically by a failure of normal mineralization of bone and epiphyseal cartilage and clinically by skeletal deformity in growing children. The four principal causes of rickets are; vitamin D deficency, renal tubular insufficiency, chronic renal insufficiency, and hypophosphatasia. Of these, vitamin D resistant rickets may result from primary defect in function of the renal tubular reabsorption for phosphorus, later accompsnied with secondary hyperparathyroidism. We experiened a rare case of hypophosphstemic vitamin D resistant rickets accompanied with secondary hyperparathyroidism in adolescence.

Apert described acrocephalosyndactyly as a clinical entity in 1906. At first he included a patient with craniofacial deformities combined with syndactyly of both the upper and lower extremities. This is a rare congenital disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. More than 200 cases have been reported in the world literature, and three cases in Korea. Authors experienced one case of the classic pattern of Apert's syndrome and treated surgically for syndsctyly.

PURPOSES: This study examined the relationship between risk behaviors and sexual knowledge, sexual attitudes, and sexual experiences of male high school students. METHOD: A cross-sectional, descriptive study was conducted. Data were collected from 2 male high schools in metropolitan Gwangju. Five hundred forty-eight boys were enrolled in this study. Descriptive statistics, factor analysis, t-test or ANOVA, and Pearson's correlation were used for data analysis. RESULTS: The mean sexual knowledge and sexual experience scores were relatively low, 0.60 out of 1 point, and 0.75 out of 4 points, respectively. Three attitude types of the students were identified: permissible, conservative and pleasure seeking attitude. The score of the permissible type was affected by the subjects' exposure to pornographic material. The score of the conservative type was affected by alcohol consumption and acquaintances with a heterosexual friend. The score of the pleasure seeking type was affected by their exposure to pornographic material, alcohol consumption, smoking, going to a video-room, and acquaintances with a heterosexual friend. There was a negative correlation between the permissible type and sexual knowledge, and a positive correlation between the conservative and pleasure seeking types and sexual experience. CONCLUSION: Male high school students who have been exposed to risk behaviors have a higher likelihood of indulging in sexual activity, and the pleasure seeking type appears to be related to sexual experience. An educational program may be needed to prevent risky behaviors and sexual experiences in male high school students considering their sexual attitude type.

BACKGROUND AND PURPOSE: The systemic inflammatory response syndrome(SIRS), as defied recently by critical-care specialists, may result from various etiologies including infection, bum, or trauma. The purpose of this study was to determine whether TNF- alpha is associated with the development of systemic inflammatory response syndrome caused by multiple trauma. METHODS: The study population consisted of 21 patients with multiple trauma presented emergency department within 2 hours after insult were enrolled in this study Multiple blood samples were serially drawn to measure seam TNF-alpha level on admission, 12 hours, 24 hours, and every day until 5 days after injury. Serum TNF-alpha was measured by ELISA ("Sandwich type"). Blood samples of fifteen volunteers were used as a reference value far serum TNF-alpha. RESULTS: Serum TNF-alpha. levels of SIRS group were persistency elevated above reference value until 3 days after on admission. Peak seam TNF-alpha level at 12 hours after admission was higher in SIRS group than non-SIRS group(p< 0.05). There was no significant correlation between injury severity score and TNF-alpha levels on regression analysis, all patients with ISS higher than 16 had SIRS. No one had SIRS among patients with ISS less than 16. CONCLUSION: the result of this study suggests that persistent elevation of TNF-alpha and degree of injury severity are associated with the development of systemic inflammatory response syndrome in multiple trauma.

Allogenic peripheral blood stem cell transplantation could be used instead of allogenic bone marrow in treatment of leukemia in children. This 10-year-old female patient with high-risk acute lymphoblastic leukemia received a myeloablative regimen followed by allogenic peripheral blood stem cell transplantation from an HI A-identical sibling donor. Neutrophil recovery to greater than 500/pL occurred at day 11 and platelets recovered to greater than 20,000/pL at day 13. Allogenic peripheral blood stem cell transplantation can be performed safely and may result in a rapid neutrophil and platelet engraftment, without any apparent increased risk of acute graft versus host disease.
