A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness.
Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and
subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid
bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on
two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or
MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus
with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone
may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

Human mitochondrial DNA (mtDNA) is generally used to identify highly degraded forensic samples, particularly when the extracted DNA is not sufficient for nuclear DNA analysis. However, direct sequencing, the most widely used mtDNA analysis method, is laborious and time-consuming, and precludes the simultaneous analysis of many samples. Here, we describe a rapid and simple screening method for mtDNA analysis in Koreans using single base extension (SBE) methods. Sixteen highly polymorphic mtDNA SNPs from the control region were selected, and a multiplex SBE system was constructed to analyze them. Because the developed system consists of two duplex PCRs, which produce small amplicons with fewer than 270 bp, it works well with highly degraded samples such as old skeletal remains. Using this multiplex SBE system, 145 different haplotypes were expected to be observed from 593 unrelated Koreans. Seventy-three haplotypes were expected to be observed only once, and the most frequent haplotype was expected to occur 80 times. Since the mean number of pairwise differences was estimated to be 4.55, the developed system could be useful to exclude samples that do not match evidence and reference samples. Therefore, the multiplex SBE system used in this study will be a useful tool to analyze many samples simultaneously and to efficiently screen out non-matching mtDNA sequences in forensic casework.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

Agenesis of corpus callosum occurs sporadically and may be transmitted as sex-linked, or autosomal-dominant or recessive traits. It has been associated with different syndromes. Clinical pictures vary from severe intellectual and neurologic abnormalities to asymptomatic and normaly intelligent cases. Agenesis of corpus callosum may occur alone, but it is more frequently associated with a high incidence of other anomalies. We report a male infant with agenesis of corpus callosum who was diagnosed to have ileal atresia and duplication.

BACKGROUND: The purpose of this study was to find the factors associated with becoming obese children during the past 2 years in 6th grade children of elementary school and then to evaluate the high risk groups for childhood obesity. METHODS: The 738 children from May to June, 2001 in 6th grade of 5 elementary schools in Busan were the subjects of this study. The children's height and weight in 4th grade and 6th grade were obtained from school health records. We calculated the body mass index in 4th and 6th grades and classified into 3 weight groups (normal, at risk for obesity, and obese) according to the age and sex-specific BMI established by the Korean Academy of Pediatrics. If children's weight group in 4th grade was changed to heavier weight group in 6th grade, we defined it as increased group. Otherwise, we defined it as non-increased group. The association between the increase in weight group and parental and children's characteristics were analyzed by x2-test, x2-test for the trend, t-test, ANOVA and multiple logistic regression. RESULTS: Among the total, 3.3% of children with normal weight and 16.9% of children at the risk for obesity in 4th grade were transformed to increased group in 6th grade, respectively (P<0.001). Children who had excessive appetite (P<0.001), watched TV greater than or equal to 2 hours per day (P=0.004) or had an obese father (P=0.044) were more likely to become increased group. After adjusting for father's obesity, appetite and TV watching time in children, the odds ratio of transforming to increased group after 2 years in children at risk for obesity or in obese child in 4th grade was 2.5 (95% CI: 1.09~5.55) compared to children with normal weight. Children having excessive appetite were 3.2 times (95% CI: 1.42~7.01) more likely to become the increased group after adjusting for father's obesity, TV watching time and weight in 4th grade. Children watching TV greater than or equal to 2 hours/day was 2.8 times (95% CI: 1.27~6.18) more likely to become increased group after adjusting for father's obesity, appetite and weight in 4th grade. CONCLUSION: The risk of becoming obese was higher in children at risk for obesity or obese children in those with excessive appetite or those who have watched TV> or =2 hours/day for the past two years. These findings suggest promotion of educational plan to prevent childhood obesity.

Angiosarcoma is a rare primary malignancy occurring anywhere in the body, but most often in the skin, liver or breast. The radiological findings of angiosarcoma of the breast have rarely been reported. We encountered a case in which the condition involved a 32-year-old woman in whom mammography revealed a obscuved-marginated and lobular-shaped high-density lesion, and ultrasonography demonstrated an ovalshaped, microlobular-marginated, inhomogenous hypoechoic mass which metastasized to the whole body after surgery. We report the radiological findings of this case of angiosarcoma of the breast, and review the literature.

OBJECTIVE: To investigate the association between endometriosis and polymorphisms of N-acetyl transferase 2 (NAT2), glutathione S-transferase M1 (GSTM1), and cytochrome P450 (CYP) 1A1 genes in Korean infertile patients. MATERIALS AND METHODS: A total of 303 infertile patients who had undertaken diagnostic laparoscopy during January, 2001 through December, 2003 at Samsung Cheil Hospital enrolled in this study. The patients were grouped according to laparoscopic findings: minimal to mild endometriosis (group I: n=147), moderate to severe endometriosis (group II: n=57), normal pelvic cavity (n=99). Peripheral blood was obtained and genomic DNA was extracted. The genotypes of each genes were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). For NAT2, RFLP was used to detect the wild type (wt) and mutant (mt) alleles, enabling classification into slow (mt/mt) or fast (wt/wt or wt/mt) acetylation genotypes. For GSTM1, PCR was used to distinguish active (+/- or +/+) from null (-/-) genotypes. For CYP1A1, MspI digestion was used to detect the wild type (A1A1), heterozygote (A1A2) or mutant (A2A2) genotypes. RESULTS: The genotype frequencies of NAT2 slow acetylator was 12.8%, 10.9%, 12.8% in group I, group II and control, respectively. The genotype frequencies of GSTM1 null mutation was 55.3%, 41.8%, 53.2% in group I, group II and control, respectively. The genotype frequencies of CYP1A1 MspI polymorphism was 16.3%, 9.1%, 18.1% in group I, group II and control, respectively. No significant difference was observed between endometriosis and normal controls in the genotype frequencies of the NAT2, GSTM1, CYP1A1 MspI polymorphism. CONCLUSION: The NAT2, GSTM1, CYP1A1 gene polymorphism may not be associated with the susceptibility of endometriosis in Korean women.

PURPOSE: The aim of this study was to investigate the alterations of growth and bone metabolism in SDR induced by dexa administration and to evaluate the effects of GH treatment in dexamethasone(dexa) induced growth and bone metabolism in SDR. METHODS: Forty-five female Sprague-Dawley rats(weight 150-170gm) were divided in 3 groups: Group 1(n=15) received normal saline as control, Group 2(n=15) received dexa(1mg/kg/day), Group 3(n=15) received dexa and rhGH(LG Chem, 1IU/kg/day) simultaneously. Group 2 and 3 were injected rhGH daily, 6 days per week. Each group was divided in three subgroups(n=5) and sacrificed at 4, 6, 8 weeks, respectively. RESULTS: In Group 2, the length of tibia and femur and tibia epiphyseal plate thickness decreased significantly at 4, 6, 8 weeks compared to Group 1, respectively. In Group 2, serum IGF-I and PICP level also decreased at 6, 8 weeks and serum ICTP level increased at 4, 6 weeks compared to Group 1 significantly. In Group 3, the length of tibia and femur increased at 4, 6, 8 weeks compared to Group 2 but there was no statistical significance. In Group 3, tibia epiphyseal plate thickness increased significantly at 6, 8 weeks compared to Group 1. In Group 3, serum IGF-I and PICP level increased significantly at 4, 6, 8 weeks respectively compared to Group 2. But serum ICTP level showed no changes between two groups. Serum PTH level increased in Group 2 compared to Group 1, and decreased in Group 3 compared to Group 2 but no statistical significance was noted, respectively. CONCLUSION: Our data suggest that dexa inhibits longitudinal bone growth and interferes with bone metabolism, both inhibiting bone formation and stimulating bone resorption in SDR. Simultaneous GH administration may abolish alterations of growth and bone metabolism induced by dexa in SDR.
