Intramural pregnancy is one of the rare forms of ectopic pregnancy and the optimal treatment is unknown. We describe two cases of intramural pregnancy treated with systemic methotrexate, which were diagnosed by pelvic MRI. Medical treatment with methotrexate may be a conservative treatment alternative for intramural pregnancies.

OBJECTIVE: The purpose of this study was to investigate the association between the T102C polymorphism in the serotonin 2A receptor gene and attention-deficit/hyperactivity disorder (ADHD) in Korean patients. METHODS: A total of 189 Korean children with ADHD as well as both parents of the ADHD children and 150 normal children participated in this study. DNA was extracted from blood samples from all of the subjects, and genotyping was conducted. Based on the allele and genotype information obtained, case-control analyses were performed to compare the ADHD and normal children, and Transmission disequilibrium tests (TDTs) were used for family-based association testing (number of trios=113). Finally, according to the significant finding which was showed in the case-control analyses, the results of behavioral characterastics and neuropsychological test were compared between ADHD children with and without the C allele. RESULTS: In the case-control analyses, statistically significant differences were detected in the frequencies of genotypes containing the C allele (chi2=4.73, p=0.030). In the family-based association study, TDTs failed to detect linkage disequilibrium of the T102C polymorphism associated with ADHD children. In the ADHD children, both the mean reaction time and the standard deviation of the reaction time in the auditory continuous performance test were longer in the group with the C allele compared to the group without the C allele. CONCLUSION: The results of this study suggest that there is a significant genetic association between the T102C polymorphism in the serotonin 2A receptor gene and ADHD in Korean children.

OBJECTIVE: The aim of this study was to investigate the gene expression profiles using GeneFishingTM kit in human placentae and their membranes delivered at preterm caused by preterm labor. METHODS: Specimens were obtained from placenta, chorion, and amnion delivered at preterm and term, respectively. Total RNAs were isolated from each specimen. Thereafter, the profiles of expression genes between preterm and term specimens were compared using a new and accurate reverse transcription-polymerase chain reaction (RT-PCR) that involves annealing control primers (ACPs) to identify the genes expressed differentially and screened by basic local alignment search tool (BLAST) search. RESULTS: Using 20 ACPs, 13 differentially expressed genes (DEGs) were identified and sequenced. 7 of them were expressed up-regulation, while 6 were expressed down-regulation in preterm deliveries. A BLAST searches revealed that 11 were known genes and 2 were unknown genes. Among known genes, up-regulated genes were insulin-like growth factor II associated protein, vigilin, acyl-Coenzyme A dehydrogenase, tissue inhibitor of metalloproteinase 1 (TIMP1), ribosomal protein S26 (RPS26), follistatin-like 1 (FSTL1) and down-regulated genes were two mitochondrial DNAs, ribosomal protein S28 (RPS28), transglutaminase 2 (TGM2), heparin sulfate proteoglycan (HSPG, perlecan). CONCLUSION: This study shows that the ACP system is a good method for the identification of preterm-related genes. Furthermore, this study suggests that further analysis of the differentially expressed genes in preterm we have identified should provide insights into the molecular basis of preterm delivery caused by preterm labor.

OBJECTIVES: The aim of this study was to investigate the association between Korean ADHD patients and the l/s polymorphism of serotonin transporter(5-HTTLPR). METHODS: The study sample consisted of 189 Korean ADHD children diagnosed by Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version(K-SADS-PL), both parents of ADHD children, and 150 normal children. DNA were extracted from the blood of all samples, and genotyping was done. Based on the allele and genotype information, not only the case-control analysis between ADHD and normal children but also the family-based association test among ADHD children and their parents. Transmission disequilibrium test(TDT) were performed for family-based associated test(number of trio=113). The results of the clinical rating and neuropsychological tests were compared according to the l/s genotype of ADHD children. RESULTS: In case-control analysis, there were no statistically significant difference of l/s gene polymorphism between ADHD and normal children in various kinds of analysis condition. In family-based association study, TDT failed to detect linkage disequilibrium between l/s gene polymorphism and ADHD in whole ADHD families. However, in the families of ADHD inattentive type only(number of trio=23), l allele was transmitted more preferentially in the proband with ADHD even if the number of families was small(chi-square=4.57, p=.032). In the analysis of the results from the clinical scales and neuropsychological tests in ADHD children, the score of the Novelty- Seeking of ADHD children with l/l genotype was significantly lower than with the other genotypes(F=3.15, p=.047), and that of Self Transcendence was significantly higher(F=4.25, p=.017). CONCLUSION: The results of this study suggest there were no significant genetic association between the 5- HTTLPR gene polymorphism and Korean ADHD.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder with a strong genetic component. Brain-derived neurotrophic factor (BDNF), which participates in the differentiation and survival of dopaminergic and noradrenergic neurons, could play a role in ADHD development. We aimed to explore the relationships between ADHD and BDNF gene polymorphism. METHODS: We conducted a case-control analysis of 202 ADHD subjects and 159 controls, performed a transmission disequilibrium test on 151 trios, and compared the results of a continuous performance test (CPT) according to the genotype of the three single nucleotide polymorphisms (rs11030101, rs6265, rs16917204) in the BDNF gene. RESULTS: In the case-control analysis, the AA genotype of the BDNF rs11030101 polymorphism was significantly associated with ADHD only in girls (p=0.024, odds ratio=3.00). The T-G-G haplotype was significantly less frequent (p=0.005) and A-G-G was more frequent (p=0.048) in girls with ADHD than in control girls (global p=0.027). A multivariate analysis of variance for commission errors on the CPT showed a significant main effect for the rs11030101 genotype (p=0.026) and an interaction effect of the rs11030101 genotype and gender (p=0.032) in ADHD probands. CONCLUSION: These results provide preliminary evidence for a gender-specific association between BDNF and ADHD in the Korean population.

PURPOSE: In this study, we analyzed the short term changes of thyroid function, incidence and risk factors of thyroid dysfunction soon after allogeneic hematopoietic stem cell transplantation (HSCT) in children. METHODS: We enrolled 80 pediatric patients following allogeneic HSCT, at the Catholic HSCT center between January, 2004 and February, 2006. Serum TSH (thyroid stimulating hormone), total serum thyroxine and total serum triiodothyronine levels were systematically measured in 80 patients before the HSCT, and at 1 month, 6 months and 12 months after HSCT. RESULTS: Thyroid function statistically decreased at 1 month after HSCT(P < 0.001). Thyroid dysfunction at 1 month was observed in 43 (54 percent) of 80 patients, 31 (39 percent) of whom presented with euthyroid sick syndrome (ETS). Thyroid dysfunction was normalized within 1 year after HSCT. In univariate analysis, malignant disease and the presence of acute graft-versus-host disease (grade > or = II) were risk factors for ETS (P=0.04, 0.01 respectively). In multivariate analysis, we could not detect an independent risk factor for ETS (P=0.19, 0.06 respectively). CONCLUSION: The present study suggests that the incidence of thyroid dysfunction is high after allogeneic HSCT. Therefore, regular monitoring of thyroid hormone levels after HSCT is required.

OBJECTIVES: Neurobiological and pharmacological research has suggested that the dysregulation of the central noradrenergic systems might be involved in the pathophysiology of ADHD. The aim of this study was to examine the association of the alpha- 1C-adrenergic receptor gene (ADRA1C) with ADHD in Korean subjects. METHODS: In a case-control study, we assessed 186 DSM-IV ADHD probands and 150 normal controls. One hundred and eight trios were studied in a family-based association analysis. Psychiatric diagnoses were derived through structured diagnostic interviews. For the clinical evaluation of the ADHD subjects, the Child Behavior Checklist (CBCL), the ADHD Rating Scale-IV (ARS) and the Junior Temperament and Character Inventory (JTCI) were administered. A computerized continuous performance test (CPT) was used to measure the inattention and impulsivity of the ADHD children. RESULTS: There were no significant differences in the genotype or allele frequencies of the ADRA1C PstI polymorphism between the ADHD and control group (p<0.05). The transmission disequilibrium test (TDT) analysis observed no evidence for biased transmission of any of the alleles of the PstI polymorphism. There were no significant differences in the CPT or JTCI profiles between those ADHD subjects with the CC genotype and those with the other (CT+TT) genotypes at the PstI polymorphism. CONCLUSION: The results of this study do not support the ADRA1C as a major genetic susceptibility factor in ADHD.

PURPOSE: Neutropenia is common in patients receiving myelotoxic chemotherapy. The aim of this study is to compare the efficacy, safety and adverse events between prophylactically administered Leukokine and Grasin. METHODS: An open-label, randomized, phase III study was designed to compare the effects of a subcutaneous injection of Leukokine (CJ Corp.) 100mug/m2 with Grasin (Jeil Pharm. Inc.) in patients receiving induction chemotherapy for acute leukemia. All patients received one dose of G-CSF every day during the study period. Total period of G-CSF injection was not over 14 days. The administration of G-CSF began on day 14 after beginning of chemotherapy under CCG strategy. In other chemotherapies, the injection of G-CSF started on day 1 from end of chemotherapy. Injection of G-CSF stopped after absolute neutrophil count recovery was achieved. RESULTS: The median numbers of times of administration were 9.6 (2~14) /cycle for Leukokine and 8.8 (2~14) /cycle for Grasin. The time to needed for neutrophil recovery more than 1, 000/mm3 was 6.6 4.9 day and 4.7 4.8 day of the Leukokine and Grasin, respectively (P=0.14). The mean duration of neutropenia less than 500/mm3 was 7.6 5.6 days for Leukokine and 6.1 6.0 days for Grasin (P=0.28). The results for the two groups were also not significantly different in adverse events, physical examination and laboratory findings. CONCLUSION: Leukokine was safe and well tolerated in these patients population. Injection of Leukokine provided neutrophil recovery with safety and efficacy similar to that provided by Grasin.
