There is an increased prevalence of imprinting disorders, such as Beckwith-Wiedemann syndrome, associated with human assisted reproductive technologies (ART). Work on animal models suggests that in vitro culture may be the source of these imprinting errors. However, in this study we report that, in some cases, the errors are inherited from the father. We(More)
BACKGROUND & AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is indispensable for the diagnosis of solid pancreatic lesions (SPLs). However, initial attempt of EUS-FNA can be inconclusive. We retrospectively evaluated the ability of repeat EUS-FNA at a tertiary referral hospital to obtain a conclusive cytological diagnosis after the(More)
BACKGROUND AND AIM Published studies have revealed the diagnostic yield of cytology obtained from endoscopic retrograde cholangiopancreatography (ERCP) in distinguishing malignant and benign intraductal papillary mucinous neoplasm (IPMN). However as a result of small sample sizes, the overall magnitude of benefit is unknown. Additionally, the optimal(More)
AIM Percutaneous Endoscopic Gastrostomy (PEG) placement is a useful but invasive method. Recently, the hemodynamic change of ultrathin transnasal esophagogastroduodenoscopy (transnasal EGD) was reported as less than that of conventional transoral EGD (transoral EGD). This study compared hemodynamic changes between transnasal EGD and transoral EGD in the(More)
BACKGROUND Clinical studies have demonstrated that oxaliplatin, a novel platinum derivative, is a potent chemotherapeutic agent, especially when combined with other reagents. The aim of the present study was to explore the mechanism of such action. METHODS Using colon cancer cell lines, we examined changes in cell cycle, apoptosis and mitotic catastrophe(More)
BACKGROUND/PURPOSE To analyze the value of ultrasound scan (US) in the preoperative identification of a contralateral patent processus vaginalis (CPPV), the authors investigated the presence of CPPV by US in children with clinically diagnosed unilateral inguinal hernias. METHODS Three hundred forty-eight patients (168 boys and 180 girls) with unilateral(More)
OBJECTIVES Differential diagnosis of malignant and benign intraductal papillary mucinous neoplasms (IPMNs) is essential to determine the optimal treatment. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is currently used to diagnose pancreatic cystic lesions worldwide, but few studies have focused on the diagnostic yield to distinguish(More)
The aim of this study was to review the efficacy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) in diagnosing gallbladder (GB)-protruded lesions. Thirty-eight patients underwent CH-EUS for the diagnosis of GB-protruded lesions. Twenty-four patients whose major axes of their largest lesions were longer than 10 mm were recruited. The(More)
An 85-year-old woman with rectal carcinoma was referred to our hospital for surgical treatment. She had a history of constipation treated with oral magnesium oxide. She received 34 g of magnesium citrate (Magcolol P(®)) orally for 2 days as a mechanical bowel preparation prior to the operation. Just before the operation, she suddenly developed nausea,(More)
Although a 64-year-old man with pancreatic cancer was referred to our hospital due to difficulty in the bile drainage, he was initially planned to have an operation at another hospital after relief of obstructive jaundice. Laboratory tests on admission revealed obstructive jaundice, pancreatitis and malnutrition (T-Bil 12.1 mg/dL, AMY 1170 IU/L, Alb 2.0(More)
