BACKGROUND Percutaneous transhepatic cholangioscopy (PTCS) has a major role in the treatment of hepatolithiasis. The aims of this study were to evaluate immediate and long-term results of PTCS treatment and to elucidate the risk factors for recurrence of stones or cholangitis. METHODS A retrospective study was conducted of patients with hepatolithiasis(More)
OBJECTIVES The present study was performed to evaluate the frequency of bipolar disorders among patients (a) presenting with depressive episodes but (b) who have never been diagnosed with bipolar disorder (c) in routine clinical practice in Korean subjects and to identify which clinical features were helpful in discriminating bipolar patients from unipolar(More)
Adverse effects of atypical antipsychotics (AAP) can include obsessive-compulsive (OC) symptoms. Based on biological evidence of the relationship between the glutamatergic system and both OC disorder and AAP, this study aimed to determine whether DLGAP3, coding a post-synaptic scaffolding protein of glutamatergic synapses, is associated with AAP-induced OC(More)
CONTEXT Several studies have indicated that atypical antipsychotics (AAP) induce obsessive-compulsive (OC) symptoms. Research exploring the mechanism of this phenomenon, however, has been extremely limited. Considering the indirect evidence of genetic control and difficulties in developing animal models and performing gene expression studies, genetic(More)
BACKGROUND AND STUDY AIMS Incomplete pancreas divisum (PD) has been generally regarded as merely a normal anatomic variant, without clinical implications. This study compares the prevalence, symptom occurrence rate, clinical presentation, and outcomes of endoscopic treatment in patients with incomplete PD and those with complete PD. PATIENTS AND METHODS(More)
The gene encoding D-amino acid oxidase (DAO), which acts as a receptor for the schizophrenia-associated neurotransmitter, N-methyl-D-aspartate (NMDA), is regarded as a potential candidate gene for schizophrenia. However, the potential association of the DAO gene with schizophrenia has been the subject of some debate. Here, we tested three single nucleotide(More)
There have been numerous studies on the association between 5-HTTLPR (polymorphisms in the promoter region of the serotonin transporter gene) and anxiety-related personality traits, with conflicting results. In this study, we administered Korean version of the Temperament and Character Inventory (K-TCI) to a sample of 158 Korean college students and(More)
The 116C/G polymorphism in the promoter region of XBP1 is known to be associated with bipolar disorders. The G allele of the XBP1-116C/G polymorphism has reduced XBP1-dependent transcription activity compared with the C allele. Valproate treatment has been known to rescue the impaired response of cells with the G allele. We investigated the hypothesis that(More)
AIM To compare the frequency of alleles and genotypes in brain-derived neurotrophic factor (BDNF) val66met polymorphism in ethnically homogenous Caucasian (from Croatia) and ethnically homogenous Asian (from South Korea) healthy participants, as inter-population differences in BDNF val66met may be responsible for the divergent findings in genetic and(More)
OBJECTIVE Genetic variation in the serotonin-2C receptor encoded by the HTR2C gene is one of the genetic determinants of antipsychotic-induced weight gain. Peroxisome proliferator-activated receptors are nuclear receptors regulating the expression of genes involved in lipid and glucose metabolism. In this cross-sectional study, we investigated whether(More)
