A low grade endometrial stromal sarcoma is a rare malignant tumor in woman. We experienced this infrequent malignant tumor in a 36 years old woman showing metas- tasis to both ovaries, omentum, rectum and mesenteric lymph nodes, and she was treated by total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by VAC(vincristi n, actinomycin, cyclophoshamide) chemotherapy. The authors report this case with the clinicopathologic findings and brief review of literature.

PURPOSE: Adolescence is a period of growth and development in body structure and physiologic, psychologic, and social functioning. Smoking and drinking in this period are very harmful and may lead to other forms of substance abuse. We surveyed the actual aspects of smoking and drinking among Korean adolescents and analyzed associated factors. METHODS: A survey was performed among adolescents using a questionnaire about smoking and drinking. Data were collected from students who visited pediatric clinics for routine school examinations from July to November 2007. RESULTS: A total of 2,546 adolescents (smoking 1,512; drinking 1,034) participated in the study. The overall smoking and drinking rates were 29.2% and 48.2%, respectively, and the mean age at the first instance of smoking and drinking was 13.8 and 14.1 years, respectively. Among drinking adolescents, 30.1% were offered a drink by their parents, although most adolescents were encouraged to smoke or drink by their friends. Dissatisfaction with family and school life, economic status, and school performance was associated with a higher smoking and drinking rate (P<0.001). Broken families were associated with a high rate of smoking, but peer satisfaction was not related to smoking or drinking. The frequency and amount of smoking and drinking in adolescents were as high as those in adults. Social sanctions seemed insufficient to keep adolescents from smoking and drinking. CONCLUSION: Adolescent smoking and drinking are highly influenced by family and school environments, so more active social sanctions are required, including parental involvement and legislation preventing adolescents from smoking and drinking.

OBJECTIVE: The purpose of this study is to evaluate the effect of functional electrical stimulation (FES) on hemiplegic shoulder subluxation in post-acute stroke patients. METHOD: Forty-four patients who had shoulder subluxation as a consequence of their first stroke were included and randomly assigned to either a control group (22 subjects) or a study group (22 subjects). Patients in both groups received physiotherapy and used an arm sling. The study group received, FES therapy to shoulder muscles (supraspinatus and posterior deltoid) for 30 minutes, five days a week for 6 weeks. The effect of FES therapy was evaluated by assessment of the severity of subluxation using radiologic measurements before and after treatment. RESULTS: 1) The severity of subluxation was significantly increased after 6 weeks (p<0.05) in the control group. In the study group, it was reduced but the difference was not statistically significant (p>0.05). 2) In the group of patients with early treatment (onset duration, less than 6 months), the control group showed a significant increase in subluxation (p<0.05), but the study group showed significantly reduced (p<0.05) shoulder subluxation after treatment period. 3) In the group of patients with mild shoulder subluxation before treatment (less than 1 finger breadth), the control group showed a significant increase in subluxation (p<0.05), but the study group showed significantly reduced (p<0.05) shoulder subluxation after treatment period. CONCLUSION: The FES therapy is effective in preventing and reducing the severity of hemiplegic shoulder subluxation in post-acute stroke patients, especially if duration since stroke onset was less than six months and the severity of subluxation before treatment was mild.

Leptin, the product of ob gene, is an endocrine hormone that regulates adipose tissue mass. Recently, leptin has been found to generate a growth signal involving a tyrosine kinase-dependent intracellular pathway and promote angiogenic processes via activation of leptin receptor (Ob-R) in endothelial cells. However, it is not clear how leptin functions to promote multi-step processes involved in the neovascularization at the atherosclerotic plaque. We have examined the expression of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) and Ob-R in human atherosclerotic lesions, leptin-mediated angiogenesis in vivo and in vitro. Immunohistochemical analysis of human atherosclerotic aorta revealed an increased expression of Ob-R in the intima of neorevascularized regions and of both MMPs and TIMPs predominantly in the endothelial lining of intimal neovessels and macrophages/foam cells. In the rat corneal angiogenesis assay, leptin elicited a comparable sensitivity of angiogenic activity to those of vascular endothelial growth factor (VEGF). The immunohistological analysis of the leptin-treated rat cornea showed definitive rises in Ob-R, MMPs and TIMPs expression as well as those of VEGF receptor (VEGFR-1). Leptin (10-40 ng/ml) induced proliferation of the human umbilical vein endothelial cells (HUVECs) and elevation of MMP-2, MMP-9, TIMP-1, and TIMP-2 expression in a dose-dependent manner. Leptin also induced increases of MMP-2, MMP-9, TIMP-1, and Up-regulated the human coronary artery smooth muscle cells (HCASMCs). These findings suggest that leptin, a hormone with pluralistic properties including a mitogenic activity on vascular endothelial cells, plays a role in matrix remodeling by regulating the expression of MMPs and TIMPs. Taken together, our findings further provide evidences for leptin's role as an angiogenesis inducer in the normal organ (rat cornea) and in aberrant vasculature under duress like atherosclerosis.

Twin pregnancies are increasing these days due to recent development of the technology in treating infertility and twin pregnancies tend to cause more congenital anomaly than singleton pregnancies do. Although anencephaly is not uncommon, occurring in about one in every 1,000 births, anencephaly developed in a twin pregnancy is very rare. We experienced a twin pregnancy which consisted of an anencephalic fetus and a normal one. This pregnancy was conceived by IVF and ET. This pregnancy was continued without having special problems and was delivered at 36 weeks of gestation by cesarean section due to SROM (spontaneous rupture of membrane). The anencephalic fetus weighed 1,430 gm and was already dead in the uterus. The other weighed 2,660 gm and showed no external anomaly. Its Apgar score was 8 in 1 minute and 9 in 5 minute. The pregnancy resulted in a cesarean section delivery of one dead anencephalic fetus and one normal healthy fetus. We report with a brief review of literature a case of a twin pregnancy, conceived by IVF and ET, in which anencephaly was associated with a normal fetus.

PURPOSE: To evaluate the quantitative accuracy of three-dimensional (3D) images by means of comparing distance measurements on the 3D images with direct measurements of dry human skull according to slice thickness and scanning modes. MATERIALS AND METHODS: An observer directly measured the distance of 21 line items between 12 orthodontic landmarks on the skull surface using a digital vernier caliper and each was repeated five times. The dry human skull was scanned with a Helical CT with various slice thickness (3, 5, 7 mm) and acquisition modes (Conventional and Helical). The same observer measured corresponding distance of the same items on reconstructed 3D images with the internal program of V-works 4.0 TM (Cybermed Inc., Seoul, Korea). The quantitative accuracy of distance measurements were statistically evaluated with Wilcoxons' two-sample test. RESULTS: 11 line items in Conventional 3 mm, 8 in Helical 3 mm, 11 in Conventional 5 mm, 10 in Helical 5 mm, 5 in Conventional 7 mm and 9 in Helical 7 mm showed no statistically significant difference. Average difference between direct measurements and measurements on 3D CT images was within 2 mm in 19 line items of Conventional 3 mm, 20 of Helical 3 mm, 15 of Conventional 5 mm, 18 of Helical 5 mm, 11 of Conventional 7 mm and 16 of Helical 7 mm. CONCLUSION: Considering image quality and patient's exposure time, scanning protocol of Helical 5 mm is recommended for 3D image analysis of the skull in CT.

Acute multifocal bacterial nephritis is a severe form of acute renal infection in which heavy leucocytic infiltrates occurs throughout kidney. Therefore, in contrast to uncomplicated acute pyelonephritis, it frequently causes acute renal failure. We here report an unusual case of acute multifocal bacterial nephritis which caused acute real failure and massive proteinuria. A 44-year old man was referred to our hospital because of high fever and both flank pain and non-oliguric acute renal failure. He had pyuria and massive proteinuria(5.87g/day), and serum creatinine level of 3.6mg/dL. We initially suspected hemorrhagic fever with renal syndrome. But immunofluorescent antibody for Hantavirus was negative and E. coli was isolated at urine. Computed tomography showed multifocal areas of wedge-shaped low densities in both kidneys. Kidney biopsy revealed tubulointerstitial infiltration of leucocyte without glomerular change. After treatment of antibiotics, proteinuria completely disappeared and serum creatinine level decreased to 1.0mg/dL.

A case of antiphospholipid antibody syndrome, accompanied by valvular heart disease and Moya moya syndrome, has never been reported. Here, we report on a case that had mitral regurgitation and Moya moya syndrome, associated with antiphospholipid antibody syndrome secondary to systemic lupus erythematosus. This patient underwent a mitral valve replacement for mitral valve regurgitation. The postoperative course was uneventful, and the pathological findings of the mitral valve showed a degenerative change, due to chronic inflammation, a proliferative fibrous change and calcification, but without thrombus formation. However, the patient returned to the hospital with a cerebral hemorrhage, which was caused by Moya moya syndrome. Surgical drainage was performed, and the patient was discharged without any complications. The patient is on anticoagulation and immunosuppression drugs, with no problems to date.

BACKGROUND: The aim of this study was to investigate the favorable factors for gonadotropin-releasing hormone (GnRH) agonist treatment with regard to the growth velocity and the predicted adult height (PAH) in central precocious puberty (CPP) girls. METHODS: We reviewed the clinical and auxological parameters in 46 CPP girls who were treated with GnRH agonist at the pediatric endocrinology clinic of Korea University Hospital from January 2001 to August 2007. We divided the two groups according to the growth velocity of 5 cm/yr and we assessed the related factors associated with growth velocity. We also assessed the changes in PAH for two years. RESULTS: The pretreatment chronological age and bone age were significantly younger in the high growth velocity group (> 5 cm/yr) compared to that of the low growth velocity group (7.8 +/- 0.9 year vs. 8.4 +/- 0.5 year, 9.4 +/- 1.2 year vs. 10.1 +/- 0.9 year, respectively) (P < 0.05). The PAH after treatment was significantly greater in the high growth velocity group (> 5 cm/yr)(P < 0.05). Growth velocity during treatment had negative correlation with the pretreatment chronological age and positive correlation with the PAH after one and two years of treatment (r = -0.45, P < 0.05 and r = 0.51, P < 0.01). PAH had positive correlation with the treatment duration (r = 0.31, P < 0.05). CONCLUSION: In our study, the growth velocity during GnRH agonist treatment was negatively related to age at the initiation of treatment. Therefore, earlier treatment is important to improve the outcomes and to maintain appropriate growth velocity in CPP girls.

OBJECTIVES: The objective of this study was to investigate the effect of pharmacological treatments for attention-deficit hyperactivity disorder (ADHD) on motor coordination, using the Developmental Coordination Disorder Questionnaire (DCDQ). METHODS: The participants were recruited from April 2015 to November 2016 from the Department of Psychiatry of Asan Medical Center and were treated for 3 months with methylphenidate or atomoxetine. The illness severity at baseline and 3 months were scored using the ADHD Rating Scale (ARS), Clinical Global Impression-Severity Scale (CGI-S) and/or Clinical Global Impression-Improvement Scale (CGI-I). A total of 39 children with ADHD (age 8.0±1.4 years, 36 boys) completed the Advanced Test of Attention (ATA) and their parents completed the DCDQ at baseline and 3 months. The paired t-test, mixed between-within analysis of variance and correlation analysis were used. RESULTS: The CGI-S (p<0.001), ARS (p<0.001), and fine motor/hand writing (p=0.005) on the DCDQ were significantly changed between pre-treatment and post-treatment. When the participants were divided into those who were suspected of having developmental coordination disorder (DCD) (n=23) and those who probably did not (n=16), the control during movement, fine motor/hand writing and general coordination scores on the DCDQ showed the main effects for group (p<0.001, p<0.001 and p<0.001, respectively). The fine motor/hand writing on the DCDQ has a significant main effect for time [F(1,37)=7.31, p=0.010, η2=0.405] and the interaction effect between group and time was also significant [F(1,37)=4.63, p=0.038, η2=0.111]. The baseline visual commission error on the ATA is significantly correlated with the changes in the DCDQ total scores (r=0.330, p=0.040). CONCLUSION: Our results provide preliminary evidence that pharmacological treatment for ADHD improves not only the core symptoms of ADHD, but also the motor coordination. Further studies are needed to confirm the effect of the pharmacological treatment for ADHD on the motor coordination.
