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.

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.

BACKGROUND: Patients treated with regional anesthesia often require concomitant medication for comfort and sedation. Propofol is widely used for this purpose, but studies upon awareness or post-operative retrograde amnesia are limited. So we designed this study to investigate the frequency of retrograde amnesia on various effect-site concentrations of propofol by using target controlled infusion (TCI). METHODS: Ninety patients (ASA I, II) undergoing orthopedic or urogenital surgery with spinal, epidural or axillary block were randomly assigned to one of six groups. Target concentrations of propofol in the six groups were respectively 1.0, 1.2, 1.4, 1.6, 1.8, or 2.0 microgram/ml. When the effect site concentration reached the target concentration in each group, we waited for 5 minutes and then lowered the target concentration to 0.5 microgram/ml. When the effect site concentration returned to 0.5 microgram/ml, we again waited for 5 minutes and then showed the patient number and picture cards and asked the patient to memorize them. Subsequently the target concentration was returned to the original level. In the post anesthesia care unit, retrograde amnesia was checked 2 hours after eye opening and then rechecked 24 hours later. RESULTS: The percentages of retrograde amnesia checked 2 hours after eye opening were 27%, 27%, 40%, 40%, 40%, and 53% (number card) and 27%, 27%, 40%, 47%, 53%, and 63% (picture card) for propofol dose of 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0 microgram/ml. A significant correlation was found between the propofol concentration and the percentage of retrograde amnesia for picture but not for the numbered cards. The percentages of retrograde amnesia observed at 24 hours after eye opening were similar to the 2 hour results. CONCLUSIONS: When propofol is used for sedation at 1.0 2.0 microgram/ml, retrograde amnesia increases in proportion to the effect site concentration. Many patients can recall intra-operative awareness, and thus we cannot be assured of effective retrograde amnesia. Therefore although a patient is under deep sedation, careful consideration of awareness and recall is needed.

PURPOSE: This study was conducted to determine the predictors of employment intention for mentally disabled persons. METHODS: Mentally disabled persons who had participated in rehabilitation programs in one of 16 mental health centers and 9 community rehabilitation centers located in Seoul and Kyunggi province were recruited for this study. A random sampling method was used and 414 respondents were used for final analysis. Data was analyzed by Pearson's correlation, and stepwise multiple regression using the SPSS Win 14.0. RESULTS: The predictors influencing employment intention of the mentally disabled person were observed as employment desire (beta=.48), guardian's expectation (beta=.26), professional's support (beta=.23), financial management (beta=.10), eating habits (beta=.07), and quality of life (beta=-.01). Six factors explained 61.1% of employment intention of mentally disabled persons. CONCLUSION: The employment intention of a mentally disabled person was influenced by employment desire, diet self-efficacy, guardian's expectation, professional's support, quality of life, financial management and eating habits.
