We experienced a case of anterior mediastinal teratoma in 26 month old boy with 2 month history of cough and dyspnea. The diagnosis was easily established by chest CAT which revealed calcific densities, while plane radiographs of chest revealed no evidence of calcification. Operation was done with good result and remained in good condition thereafter. A brief review of the related literature was made on this subject.

BACKGROUND: Following several decades of decline, the incidence of tuberculosis has recently begun to increase in many countries and the control of this disease has been impeded by the emergence of multi-drug resistant tuberculosis (MDR-TB). The development of rapid diagnostic methods and effective new drugs are needed to control MDR-TB. One of the new drugs for MDR-TB is rifabutin (RBU) which has been known to be effective in some patients with MDR-TB. A few reports showed that some types of mutaitions of the rpoB gene, which were known to be present in 96-98% of rifampicin-resistant M. tuberculosis, were associated with the rifampicin-resistant but RBU-susceptible phenotype. This study was performed to investigate the correlation between RBU susceptibility and the patterns of rpoB gene mutations in Korean MDR-TB. METHODS: Sixty-five clinical isolates of multi-drug resistant Mycobacterium tuberculosis, gathered from patients two visited the Asan Medical Center from July 1997 to June 1999, were investigated. Clinical responses to rifabutin-containing regimen were evaluated. An RBU susceptibility test and sequencing analysis of rpoB gene were performed, and the result were analyzed to confirm which mutations correlated with RBU-susceptible MDR-TB. RESULTS: Fifty-three of 56 (95%) clinical isolates of MDR-TB had 60 mutations of the rpoB gene. The most frequent mutations were found at codon 531 (43%), and two mutations were combined in seven clinical isolates. Five of 53 (10%) clinical isolates showed the RBU-susceptible phenotype, and in them the characteristic patterns of point mutations were found at codon 509, 516, and 526. CONCLUSION: The frequency and pattern of mutations of the rpoB gene of Korean MDR-Tb isolates were similar to those in western countries, where the prevalence of tuberculosis is low, but some show RBU-susceptible phenotypes. RBU-susceptible MDR-TB isolates showed the characteristic pattern of mutations of the rpoB gene which could be used to rapidly diagnose RBU susceptibility.

PURPOSE: To obtain normative data on bone mineral density of each region of interest (ROI) measured by Hologic model dual-energy x-ray absorptiometry (DXA) of children and adolescents. METHODS: Cross sectional results from 723 healthy Korean children and adolescents (10-20 years of age) in the Korean National Health and Nutrition Examination Surveys were analyzed. We used age- and sex-specific reference data for bone mineral density (BMD) of the lumbar spine, femur neck, and total body except head from Hologic DXA device as recommended by the International Society for Clinical Densitometry. RESULTS: The bone mineral density of each ROI increased with age in both boys and girls. Maximal increase in the lumbar BMD occurred between ages 11 and 12 in girls and between ages 12 and 14 in boys. However, the increases of BMD in each ROI were different. The plateaus of the lumbar spine and whole body except head BMD in girls occurred at ages 15 and 17, respectively. The plateaus of BMD in each ROI occurred at age 17 in boys. CONCLUSION: Most of the skeletal mass, including lumbar spine and total body except head, is reached before the end of the second decade. This study provides reference values for bone density of each ROI measured with DXA for children and adolescents.

BACKGROUND: There has been much interest in the involvement of wind-up in the hyperalgesia and allodynia of chronic pain syndrome. To investigate the behavioral parallels of this wind-up phenomenon, we evaluated the effects of intrathecal morphine, clonidine and MK801 on the formalin test in the rats. METHOD: All experimental animals were divided randomly into six groups. In group 1(n=7), normal saline 50 l was administered through the intrathecal catheter(PE10, 8 cm in length). In group 2(n=7), morphine 10 g was administered through the catheter. In group 3(n=7), group 4(n=7), group 5(n=7) and group 6(n=7), clonidine 10 g, clonidine 20 g, MK801 1 g, MK801 10 g was administered in same manner, respectively. Thirty min after recoverying from anesthesia, 50 l 5% formalin was injected in the hind paw. To quantify the formalin response, we counted the number of spontaneous flinching for 60 min. RESULT: Intrathecal morphine(group 2) decreased the number of paw flinches in both phases 1 and 2 readily compared to control(p<0.05). In the clonidine(group 3 and 4), both groups decreased the number of flinching in both phases 1 and 2, but there was no significant difference between two groups. In group 5, intrathecal MK-801 decreased the number of paw flinches in phase 2. In group 6, intrathecal MK-801 decreased the number of paw flinches in both phases 1 and 2. CONCLUSION: This study suggest that wind-up is readily blocked by pretreatment of morphine, clonidine and MK801.

Ror fetal sex determination by the PCR method, oilgoprimers to Y- chromosome gene, DYZI, SRY, and AMGL were synthesized genomic DNA was extracted from male and female placenta for the control use. DYZI represented 154 bp single band to 0.001 pg/ml male genomic DNA but did not represent 154 bp band in female genomic DNA, SRY represented 341 bp bandto 1 pg/ml male genomic DNA in 2% agarose gel eleftrophoresis stained with ethidium bromide. DYZI was 1,000 fold sensitive than Sry and AMGL. DYZI and SRY could not identify the PDR failure from female but AMGL identified to 1,000-fold. During the dyal ampiification of female genomic DNA mixed with male genomic DNA, 0.00125 pg/nl, 1:400 part, male genomic DNA contamination represented male band but SRY amplification did not represent male band. It was suggested that SRY gene was deleted in two 46,XY felmle cases. For fetal sex determination, PCR with DYZL, SRY, and AMGL was performed in 10 cases. For fetal sex determination, PCR with DYZL, SRY, and AMGL with karyotyping in 10 cases of chorionic villi sex dietermination, PCR with DYZI, SRY, and AMGL was performed in 10 cases. For feral sex determination, PCR with DYZI, SRY, and AMGL with karyothping result, fetal sex determination, PCR with DYZI, SRY, and AMGL was performed in 10 Cases of choricinic villi and 15 cases of amnionic cells. By the comparison with karyotyping result, fetal sex determination was achieved successfully in all 23 samlies using PCR of SRY and AMGL but false result was detected in 3 cases(13%) using DYZI. Acording to our results, it was concluded that DYZL was 1,000-fold sensitive than SRY and AMGL but could not be used because of its false results, and AMGL and SRY must be used concomitantly for precise sex determination.

OBJECTIVE: To study the clinical characteristics of pregnancy induced hypertension(PIH). METHODS: Five hundred seventy-five cases of PIH and 7,702 cases of normotensive pregnancies who were delivered their infants at Wonkwang University Hospital from January, 1994 to December, 1998 were selected for the study. The data were collected by review of the hospital record and the statistical analysis was performed using Chi-square tests, and statistical significance was defined as p<0.05. RESULTS: The incidence of PIH was 7.1% of total deliveries. Among the PIH, the incidence of mild preedampsia was found in 59%, severe preeclampsia in 36%, and edampsia in 5%. The most prevalent gestational period was 38-42wks gestation in mild PIH and 33-37wks gestation in severe PIH & eclampsia. The incidence of cesarean section was significantly higher in severe PIH & eclampsia(72.2%) than in mild PIH(48.7%) and normotensive pregnancies(39.7%). The incidence of hypoalbuminemia, preterm labor, placental abruption, disseminated intravascular coagulation, and pulmonary edema were significantly higher in severe PIH & edampsia than in mild PIH and normotensive pregnancies. Compared with normotensive pregnancies or mild PIH, severe PIH & eclampsia had significantly elevated risks for low birth weight, intrauterine growth retardation, fetal distress, low apgar score, meconium stained, and neonatal deaths. CONCLUSION: The incidence of PIH is not decreasing and it still an important role in the cause of maternal and perinatal mortality and morbidity in Korea. So, further studies are necessary to prepare a guide for the treatment of PIH.
