A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

PURPOSE: The purpose of this study was to provide basic data on preventive child abuse program development. METHOD: Data were collected on 105 high-risk families of child abuse intervention was obtained from their main child rearer who raised the child under 18 years, olds during 10 months period from May, 2000 to March 2001. RESULT: The results were as follows : 1. Child abuse occurred in the subject's home, in the case of mild child abuse, 'throwing an object at the child' had the highest percentage 39.1%, in severe child abuse, 'rod, stick, belt, broom beating or using a variety of objects such as' had the highest percentage 49.5%, and in very severe child abuse, 'hospitalized by belting' had the highest percentage 3.8%. 2. The degree of child abuse potential showed high risk child abuse score with a mean of 213.3. The degree of beliefs in corporal punishment showed that subjects perceived corporal punishment of children positively with a mean of 32.2. 3. With respect to the child abuse potential, there were significant correlations with the subjects' age (r=.294, p=.002), education level (r=-.442, p=.000), and family income (r=-.355, p=.000). CONCLUSION: From this study not only child abuse occurrence but also child abuse potential were severely increased in poor livelihood families. Therefore to the high risk group, individual preventive approach must be applied.

BACKGROUND AND OBJECTIVES: This study was intended to test how the inflammation at the Bacille Calmette-Guerin (BCG) inoculation site (BCGitis) can be a useful a diagnostic feature of Kawasaki disease (KD). SUBJECTS AND METHODS: All subjects were infants at the time of admission, and had received BCG vaccination during their neonatal period. There were 54 patients with complete KD (group 1) and 29 patients with incomplete KD (group 2). All 83 patients had BCGitis during the acute phase of illness. Data regarding the coronary artery diameters in 31 age-matched controls were used for comparison. RESULTS: The 2 patient groups did not differ in clinical and laboratory variables. During the acute phase, the median z scores of the left anterior descending coronary artery (LAD) diameter were 0.20, 0.42, and -0.48 in groups 1, 2, and control respectively, and that of right coronary artery (RCA) diameters were -0.15, -0.16, and -1.17 respectively. The z scores in both patient groups were greater than those in controls (p=0.0014 in LAD and p<0.0001 in RCA between group 1 and controls; p=0.0023 in LAD and p<0.0001 in RCA between group 2 and controls). A similar pattern was observed during the subacute and convalescent phases. CONCLUSION: BCGitis is a useful feature in the diagnosis of incomplete KD in infants who received BCG vaccine during neonatal period.

OBJECTIVE: Since IVF program was first established, various types of media and culture systems have been developed either in-house or commercially. The aim of this study was to compare the efficacy of in-house Maria Research Center (MRC) media to that of commercially available Sydney IVF media in human day 3 embryo transfer cycles. METHODS: Three hundred sixty nine couples were included in this prospective, randomized, and comparative study. All couples undergoing IVF treatment at the Maria Fertility Hospital were randomly assigned to either Sydney IVF (n=178) or MRC (n=191) media. RESULTS: No difference was observed between the MRC media and Sydney IVF media groups with respect to fertilization rate (74.4% vs. 75.5%). The clinical pregnancy and implantation rates of MRC media (47.1% and 20.0%, respectively) were also similar to those of Sydney IVF media (44.4% and 19.4%, respectively). However, the proportion of embryos with good quality on day 3 was significantly higher in the MRC media group than the Sydney IVF media group (50.2% vs. 43.2%) (p<0.05). CONCLUSION: MRC media were as effective as Sydney IVF media for sustaining embryo development and pregnancy rates. The present study implies that MRC media can be a suitable alternative to commercially available media for human IVF-ET program.

A 9-year-old Korean boy with lissencephaly was found dead at home. He had previously been diagnosed with lissencephaly that presented with infantile spasm on the basis of magnetic resonance imaging and electroencephalogram results. Antemortem chromosomal banding revealed a normal karyotype. A legal autopsy was requested to eliminate the possibility of neglect or abuse by his parents. The autopsy findings revealed type I lissencephaly with the associated microcephaly. No external wounds or decubitus ulcers were noted. Postmortem fluorescence in situ hybridization for the LIS1 locus and nucleotide sequence analysis of the whole coding regions of the LIS1 gene did not reveal any deletions. The antemortem and postmortem findings revealed that lissencephaly syndrome was associated with isolated lissencephaly sequence. External causes of death were excluded by the full autopsy and toxicology test results. Because patients with mental retardation are frequently victimized and suffer neglect or abuse, thorough external and internal examinations should be conducted at the time of autopsy.

Long QT syndrome(LQTS) is characterized by prolongation of the QT interval, frequent episodes of syncope, and ventricular tachycardia leading to sudden cardiac death in adolescents and young adults. Early diagnosis and prompt treatment to reduce the risk of life-threatening cardiac events is crucial, however sudden onset convulsive syncope may be misdiagnosed as epilepsy and lead to antiepileptic drug therapy for many years. We experienced a case of six-year-old boy who were having seizure triggered by exercise and being treated with antiepileptic drugs. He had normal EEG and brain MRI but his ECG revealed prolonged QT interval(QTc=477 ms) and treadmill test induced polymorphic ventricular tachycardia. After applying beta-blocker, he had no more seizure attacks. We report a case of long QT syndrome misdiagnosed as epilepsy with a brief review of related literatures.

PURPOSE: To describe clinical features of cyclic vomiting syndrome(CVS), managements during episodes, prophylactic drugs as long term therapy and to investigate the disease course and prognostic factors of CVS. METHODS: Thirty two children who fulfilled the diagnostic criteria of CVS and who presented to Seoul National University Children's Hospital from March 1989 to December 2000, were included. Data were obtained from chart review and telephone interview. RESULTS: All had recurrent, self-limited episodes and were free of symptoms between episodes. During the acute phase of episodes, lorazepam and ondansetron were effective in some patients. Various prophylactic drugs were tried and some patients recovered after the use of clobazam, clonazepam, erythromycin and imipramine. Among 32 patients, 18 had recovered from CVS. The age at recovery was 9.4 +/- 4.0 years. It took 3.4 +/- 2.2 years from the onset to the recovery. The age at onset was later in the recovery group than in the non-recovery group(6.1 +/- 3.2 vs 1.7 +/- 1.8 years; P=0.015) and the duration of episodes was longer in the recovery group(5.2 +/- 1.6 vs 2.3 +/- 1.2 days; P=0.003). CONCLUSION: Many patients recovered from CVS spontaneously. The prognosis in patients with later onset of the disease and the longer duration of episodes seemed to be better. Prophylactic drugs such as clobazam, clonazepam, erythromycin and imipramine may be beneficial. A total approach including trials of prophylactic drugs, removal of the triggering factor and psychiatric support is needed in the management of CVS.

Forty eight female Sprague-Dawley rats received a subcutaneous implant containing 12.5 mg estradiol ant the age of 3 weeks. Three rats were killed in 1, 2, 3, 4, 6 weeks and in every month during 2~12 months after implantation, and the breasts were examined by light microscope. In all rats, enlargement of terminal end buds was obseved in 1~2 weeks, maximum development of hyperplastic alveolar nodules in 3 weeks, and marked dilatation and secretion of alveoli or ducts in 1~12 months after implantation. Ductal epithelial hyperplasia was observed in 27 rats and carcinomas developed in 23 rats in 2~12 months after implantation. It was thought that the changes induced by estradiol are more similar to the human breast lesions, compared with changes induced by chemical carcinogens such as dimethylbenzanthracene(DMBA), because breast carcinomas developed in close relationship with ductal epithelial hyperplasia in both estradiol-treated rats and humans, but not in DMBA-treated rats.

PURPOSE: This study was conducted to evaluate the role of adiponectin, leptin, and tumor necrosis factor-alpha (TNF-alpha) in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) in obese children, and to elucidatethe relationship between these adipokines and insulin resistance. METHODS: A total of 61 obese children (M : F=42 : 19, mean age 11.2+/-1.3 years) admitted to our facility between March 2004 and June 2005 were included in this study. Patients were divided into three groups based on their NAFLD status obese children without fatty liver (N=23); obese children with simple steatosis (N=20); and obese children with non-alcoholic steatohepatitis (NASH) (N=18). The serum levels of adiponectin, leptin, and TNF-alpha were measured, and insulin resistance determined by homeostasis model assessment (HOMA-IR) was calculated to estimate insulin resistance. In addition, the VSR (visceral-subcutaneous fat ratio) was estimated using abdominal computed tomography. RESULTS: There was no difference in serum TNF-alpha and leptin levels observed between the 3 groups (22.13+/-6.37 vs. 21.35+/-6.95 vs. 25.17+/-9.30; p=0.342 & 20.29+/-8.57 vs. 16.42+/-6.85 vs. 20.10+/-7.86; p=0.330). However, the serum adiponectin level was significantly lower in children with non-alcoholic steatohepatitis (NASH) than in the other two groups (6.08+/-1.38 in children without steatosis vs. 5.69+/-0.79 in simple steatosis vs. 4.93+/-1.75 in NASH; p=0.026). In addition, the VSR was significantly increased in the NASH group (0.31+/-0.08 vs. 0.32+/-0.11 vs. 0.47+/-0.14; p=0.001), and HOMA-IR revealed a significant difference among the three groups (4.77+/-3.67 vs. 6.89+/-7.05 vs. 10.42+/-6.73; p=0.000). However, there was no significant correlation observed between the adiponectin levels and the HOMA-IR or the VSR (r=-0.117; p=0.450 & r=-0.106; p=0.499). CONCLUSION: Insulin resistance may affect the development of hepatic steatosis and steatohepatitis in children, and the results of this study suggest that, of several adipokines evaluated, adiponectin is important in the progression of steatosis to steatohepatitis in obese children.
