Clinical survey was performed on 413 cases of twin pregnancies and their 816 twin babies who were born at IlSin Christian Hospital during 5years from January 1987 to December 1991. The result of study was as follows: 1) there was 413 twin pregnancies among 40,711 deliveries, so the incidence of twins was 1:98.6. Average male-female sex ratio of twins was 1.3:1, same sex pairs rate was 86% and different sex ratio was 14%. 2) The incidence of relation with maternal age was highest between 25 years old and 29 years old but the ratio of twin delivery to total delivery was 0.9% so, was not higher than other age group. 3) The incidence of relation with maternal parity was highest at first pregnancy but the ratio of twin delivery to total delivery was highest at second pregnancies. 4) Normal birth weight infants were 45.7%, low birth weight infants were 54.3% and very low birth weight infants was 9.3%. Fullt-erm infants were 63.7% and prematurity were 35.4%. 5) The incidence of feto-fetal transfusion was 7.3%. 6) Perinatal death rate was 76.3 and was more higher in second babies. The most common cause of perinatal death was prematurity, followed by respiratory complication, congenital anomaly, infection and asphyxia. Still-births were 8 cases.

BACKGROUND: According to the areas and people that are examined, there are many differences in the prevalence of syphilis in Korea. However, the reactive rate of the serologi test for syphilis showed an increase in the 1960s, and it has deerea@sed from the beginning of the 1970s. OBJECTIVE: Comparing the results of tke serologic test for syphilis which lotad been performed for the 5 years(1987-1991) on the physical examines and pregnant women who were considered as healthy, with the results with normal people, who were considered as healthy, which had been already reported, we tried to observe the change of reactive rate of serologic test for syphili. METHODS: The serologic test for syphilis, including serum VDRL test and serum TPHA test, were carried out on 25,254 healthy adults(20,405 were physical examineea eamined at National Medical Center and 4,849 were pregnant women delivered at National Medical Cer ter). RESULTS: The reaetive rate of serum VDRL test was 0.8% in 25,25 the althy adults(physical examinees 0.8%, pregnant women 0.7%). There were no stistically differerces between the annual incidences. 85.5% of VDRL-reactive subjects showed low VDRL titers(below 1:4) by the quantitative serum VDRL test, The biologic false positive reaction of serum VDRL test was 29(19.5%) in 149 VDRL-reactive subjects, using serum TPHA test as a standard. CONCLUSION: This study suggested thai, there was a decrease in the prevslence of syphilis in Korea.

PURPOSE: To evaluate the diagnostic value of gross bloody stools as a predictor of intussusception. METHODS: We reviewed 159 cases retrospectively that had an ultrasound examination for diagnosis of intussusception from January 2001 to December 2003 at Ilsin Christian Hospital. We compared each symptom and assessed the diagnostic value of gross bloody stools in the patients with suspected intussusception. RESULTS: Thirty-six of the 159 patients had intussusception. Of 36 patients with intussusception, 19 (52.8%) children were male and 28(77.8%) children were younger than two years. The most common symptom was intermittent abdominal pain or irritability. But its frequency among the intussusception (24.2%) was lower than frequency of gross bloody stools(50.9%). The sensitivity, specificity, positive predictive value(PPV) and negative predictive value(NPV) of gross bloody stools in patients with suspected intussusception were as follows; sensitivity=77.8%(95% CI 60.8-89.9), specificity=78.0%(95% CI 69.7-85.0), PPV=50.9%(95% CI 37.1-64.6), NPV=92.3%(95% CI 85.4-96.6)(Diagnostic accuracy 78.0 %; 95% CI 70.7-84.2). CONCLUSION: It is useful for diagnosis of intussusception to confirm the presence of gross blood in stools.

The skin manifestations of secondary syphilis, termed syphilid, show macular, papular and papulosquamous rashes in most cases, but may show lots of other clinical findings. We report a case of syphitid simulating purpura annulsris telangieitodes in 25-year-old male who had a history of genital ulcer 2 months ago. The skin lesion showed diffuse erythematous, 1-3 cm sized, telangiectatic annular patchea and purpuric plaques on both lower extremities and discrete papulosquamous rashes on both soles. The results of the serologic test for syphili was found to be reactive to 32 dilution in serum VDRL test and positive in serum TPHA test. Histovathologically, we could observe the obscuring of dermoepidermal juction, coat-sleeve-like perivascular infiltrate composed of mononuclear cells and a few plasma cells, and endothelial swellings. Afte the treatment with benzathine penicillin G, the titer of serurn VDRL test was decreased abruptly to 4 dilution and the skin lesions disappeared completely.

Recently, [I-123]IPT SPECT has been used for early diagnosis of Parkinson's patients(PP) by imaging dopamine transporters. The dynamic time activity curves in basal ganglia(BG) and occipital cortex(OCC) without blood samples were obtained for 2 hours. These data were then used to measure dopamine transporters by operationally defined ratio methods of (BG-OCC)/OCC at 2 hrs, binding potential Rv=k3/k4 using graphic method or RA= (ABBG-ABOCC)/ABOCC for 2 hrs, where ABBG represents accumulated binding activity in basal ganglia(integral 0 120minBG(t)dt) and ABOCC represents accumulated binding activity in occipital cortex(integral 0 120minBG(t)dt). The purpose of this study was to examine the IPT pharmacokinetics and investigate the usefulness of simplified methods of (BG-OCC)/OCC, RA, and RA which are often assumed that these values reflect the true values of k3/k4. The rate constants K1, k2, k3 and k4 to be used for simulations were derived using [I-123]IPT SPECT and aterialized blood data with a standard three compartmental model. The sensitivities and time activity curves in BG and OCC were computed by changing K1 and k3(only BG) for every 5min over 2 hours. The values (BG-OCC)/OCC, RA, and Rv were then computed from the time activity curves and the linear regression analysis was used to measure the accuracies of these methods. The rate constants K1, k2, k3, k4 at BG and OCC were 1.26+/-5.41%, 0.044+/-19.58%, 0.031+/-24.36%, 0.008+/-22.78% and 1.36+/-4.76%, 0.170+/-6.89%, 0.007+/-23.89%, 0.007+/-45.09%, respectively. The Sensitivities for ((delta S/S)/(delta k3/k3)) and ((delta S/delta S)/(delta K1/K1)) at 30min and 120min were measured as (0.19, 0.50) and (0.61, 0.23), respectively. The correlation coefficients and slopes of ((BG-OCC)/OCC, RA, and Rv) with k3/k4 were (0.98, 1.00, 0.99) and (1.76, 0.47, 1.25), respectively. These simulation results indicate that a late [1-123]IPT SPECT image may represent the distribution of the dopamine transporters. Good correlations were shown between (BG-OCC)/OCC, RA or Rv and true k3/k4,, although the slopes between them were not unity. Pharmacokinetic computer simulations may be very useful technique in studying dopamine transpoter systems.

PURPOSE: Neonatal hyperbilirubinemia has benign courses in most cases, but the possibility of toxicity of hyperbilirubinemia required courses examination of every newborn infant to identify the severity of hyperbilirubinemia progress. This study aims to see how the body surface area of newborns influences the decline rate of serum bilirubin level in conventional phototherapy. METHODS: Based on the charts of the Pediatrics Department, Dae-Dong Hospital from January 2003 to December 2006, we analyzed 168 neonates diagnosed as neonatal hyperbilirubinemia (serum bilirubin > or =15 mg/dL) in retrospective way. We excluded newborn infants under 37 weeks of gestation and under 2,500 g birth weight and classified neonates into four groups by the calculation results of body surface area:males above 75 percentile (group A), males below 25 (group B), females above 75 (group C), and females below 25 (group D). RESULTS: Out of 168 samples, the number of group A, B, C, D was 30, 20, 20, 15 respectively. In conventional phototherapy, the mean decline rates of serum bilirubin of group B and D recording 2.09 mg/dL/day and 1.77 mg/dL/day, were significantly faster than those of group A and C recording 1.63 mg/dL/day and 1.41 mg/dL/day (P<0.01). No significant differences were found in different duration of phototherapy between groups below 25 percentile and those above 75 in both genders. CONCLUSION: In conclusion, body surface area influences of infants the decline rate of serum bilirubin level in conventional phototherapy.

A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.

Although basic mechanisms of atopic dermatitis remain largely speculative, many studies on pathogenesis suggest the importance of food and inhalent allergens. To evaluate the frequency of food and house dust mite hypersensitivity and differences in this frequency according to ages, we measured the levels of specific IgE antibodies to egg white, egg yolk, milk, soy, and house dust mites in 119 children with atopic dermatitis. The results showed that 53% of patients had positive RAST to any one kind of allergens. The frequency of food and house dust mite hypersensitivity were 34.5%, 30.3 %, respectively. Among allergens, house dust mites and egg white are the most prevalent allergens in all atopic dermatitis patients. The Prevalence of egg white is most common under the age of 2 years, but those of house dust mites are the dust mites are the highest in the ages of 5-12 years. In conclusion, we recommend an egg restriction diet in atopic dermatitis patients who are less than 2 years old when their symptoms do not improve with general skin care.
