Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.

The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.

Medulloepithelioma(diktyoma) is a uncommon congenital tumor that is generally believed to arise from the embryonic neuroepithelium of the medullary tube. This tumor usually arises from the ciliary body epithelium. But medulloepitheliomas of the retina and optic nerve may also occur, although it is extremely rare, because the embryonal medullary epithelium that lines the optic vesicle is continuous with the epithelium lining the cavity of the optic nerve during the early embryonal period. The occurrence of medulloepithelioma of the optic nerve is exceptionally rare, with only a few cases have been previously reported. We report a first case of medulloep-ithelioma of the optic nerve head in Korea in a 5-year-old girl who presented with a poor vision and squint of the left eye.

OBJECT: In order to compare several Obstetric characteristics and outmmes of teenage pregnancy. METHODS: The 10 year clinical records of 11,583 women undergoing Cesarean section and delivery were reviewed in the department of Obstetrics and Gynecology, Incheon Christian Hospital from July 1, 1989 to June 30, 1999. There were seventy-eight pregnancies under age 20 and we compared them with two hundred pregnancies aged 20-29 who were randomly chosen during the same periods as the control group. RESULT: The following results were obtained. The proportion of birth by teenagers increased from 0.5% of all birth in 1989 to 2.61% in 1999. The most of cases were in high teen group, age 14- 19.The majority(50.5%) were in the age of 19. Seventy two cases(92.3%) had no previous pregnant history. Six cases had one previous pregnant history. The frequencies of prenatal care were significantly lower than that of the control group(p<0.05). The mean gestational period was 36+4weeks, and showed significant difference between the study group and the control group(39+3 weeks). The incidence of preterm labor was significantly different between the two proups(p<0.05). But the incidence of postterm delivery were not significantly different between the two groups. The mean weight gain of pregnant teenagers revealed 10.64kg, significantly less profound than the control group. The matemal weight gain of control group revealed 12.95kg, respectively. The mean birth weight(2.54kg) of infant was significantly less profound than the control group. The incidence of birth of small for gestational age(birth weight 1,500-2,499gm ; 14.5%) was significantly increased among study group than the control group(1%). The rate of abdominal delivery(21.8%) were not significantly decreased than the control group(47%). The incidence of cephalopelvic disproportion and malpresentation for cesarean section were somewhat higher than the control group, and were statistically significant(p<0.05). During the antepartun period, anemia, pyelonephritis, and preterm labor occurred more frequently in the teenage pregnancy than the control group, but not statistically significant. Among postpartum complications, incidence of anemia(51.3%) increased significantly. The perinatal mortality, intrauterine growth retardation, congenital anomaly occurred more frequently than the control group. CONCLUSION: These results show that pregnancy of teenage will be comeout high risk and complications. And then we will be more concern and study about teenage pregnancy.

Authors reviewed clinical records of 92 patients with tetanus from January 1974 to December 1983 at Severance Hospital and the following results wre obtained. 1) There were about 2.2 times more cases of neonatal tetanus than that of nonneonatal. The admitted cases of tetanus decreased in 1980's compared to those of 1970's. 2) The male versus female ratio was 3 : 1 not only in nonneonatal but also in neonatal teanus. 3) There was a tendency of higher mortality when the site of injury was on the central part of the body than on the distal. 4) Most cases of tetanus developed after the injury with bactrial contamination as expected, but a few cases are due to only trivial injury such as acupuncture or injection without overt contamination. 5) There was a close relationship between the incubation period and mortality in neonatal tetaus but no such definite relationship in nonneonatal tetaus. 6) The duraton of admission was about 3 weeks and the majority of deaths occureed in less than one week of admission. 7) There was no statistically significant difference in mortality between the group who used tetanus antitoxin from animal and that who used human tetanus immuneglobulin.

p27kip1, a cyclin dependent kinase inhibitor, has been recognized as a negative regulator of cell cycle. To investigate the role of p27kip1 on progression of cancer and apoptotic pathway, we analyzed p27kip1 expression using immunohistochemical stain in 40 cases of prostatic adenocarcinoma and apoptotic index by TUNEL method in 30 cases of prostatic adenocarinoma. Both were correlated with Gleason grade and Gleason score. Loss of p27kip1 expression was more frequent in prostatic adenocarcinomas of higher score (Gleason score 7 to 10) (60.7%) than in those of lower score (Gleason score 4 to 6) (33.3%) (p<0.05). The value of mean apoptotic index of carcinoma was 1.13+/-0.26, 1.80+/-0.91, 2.06+/-0.79, and 2.12+/-0.82 in grade 2, 3, 4, and 5, respectively, and was positively correlated with grade of carcinoma (p<0.05). Mean apoptotic index of higher Gleason score (score 7 to 10; 2.05+/-0.63) was also significantly increased than in lower Gleason score (score 4 to 6; 1.34+/-0.39) (p<0.05). Mean apoptotic index in cases with and without p27kip1 expression was 1.92+/-0.86 and 1.89+/-0.81, respectively (p>0.05). These results suggest that loss of p27kip1 expression and increased apoptotic index may be the morphologic markers to predict the behavior of prostatic adenocaricnoma. The role of p27kip1 on apoptotic pathway seems to be meager in this study and needs further study.

10.Novel Role of Invariant Natural Killer T-cell in Glycemic Control: Regulation by human Adenovirus 36.
Journal of Bacteriology and Virology 2013;43(3):229-232
Obesity is associated with a state of chronic low-grade inflammation. This abnormal inflammation state may cause metabolic dysfunction. Many studies have supported the claim that immune cells such as adipose tissue macrophage and invariant natural killer T-cells (iNKT) are related to the development of metabolic diseases like diabetes. It has recently been reported that while human adenovirus 36 (Ad36) infection is associated with human obesity, it also helps to improve the serum level of lipid factors (glycemic control). However, the detailed cellular mechanism remains unclear. This study (The Journal of Clinical Investigation, 2012;122:3343-54) showed that iNKT cell-deficient mice on a low-fat diet used as a control for high-fat diet boasted insulin resistance phenotype without adipose tissue inflammation. The results of this study offer insight into the possibility of a novel role for iNKT related to the improvement of metabolic diseases, especially insulin resistance, and hint that Ad36-induced inflammation may be associated with iNKT in adipose tissue, while also playing a role in the improvement of glycemic control.
