BACKGROUND/AIMS In treating many cases of postoperative adhesive small bowel obstruction (ASBO), we have found that if a long tube is not effective in conservative treatment, the surgical timing requires careful consideration. The aim of this study was to clarify the limits of conservative treatment, long tube management, and surgical timing. METHODOLOGY(More)
The aim of this study was to investigate whether different fabrication processes, such as the computer-aided design/computer-aided manufacturing (CAD/CAM) system or the manual build-up technique, affect the fracture resistance of composite resin-based crowns. Lava Ultimate (LU), Estenia C&B (EC&B), and lithium disilicate glass-ceramic IPS e.max press (EMP)(More)
Carcinomatous meningitis is clinically less common than brain metastasis or spinal cord compression, but has dire consequences for both the quality of life and the overall survival of patients with various kinds of malignancies. It occurs in about 5% of all adult cancer patients, though autopsies may double this number. The primary tumors that frequently(More)
The surfaces of hydroxyapatite-glass-titanium (HA-G-Ti) functionally gradient composite and titanium bars were treated with electrochemical apatite deposition, and a cathodic current was applied at 62 degrees C in a solution containing calcium and phosphate ions. Specimens with and without the electrochemical surface treatment were implanted in the femurs(More)
INTRODUCTION Some of our patients showed a recurrence of adhesive small bowel obstruction (ASBO) with nonoperative management. The aim of this study was to evaluate the parameters predicting the recurrence of ASBO in patients managed with a long tube. METHODS Of 234 patients with ASBO admitted from April 1998 to September 2002, a total of 91 who recovered(More)
The purpose of this study was to evaluate the influence of a disinfection technique based on photolysis of H2O2 on the mechanical properties and color change of acrylic denture base resin. Resin specimens were immersed in 1 M H2O2 irradiated with light-emitting diode (LED) light at 400 nm for 1 week. The immersion duration of 1 week (168 h) corresponded to(More)
OBJECTIVES The purpose of the present study was to analyze the relationship between fracture load of monolithic zirconia crowns and axial/occlusal thickness and to evaluate the fracture resistance of monolithic zirconia crowns with reduced thickness in comparison with that of monolithic lithium disilicate crowns with regular thickness.

A 60-year-old man suffered from inoperable recurrent undifferentiated thyroid cancer and was scheduled to undergo chemotherapy. He had no known allergy to medications. In the first regimen, he was given IV granisetron and betamethasone before IV 120 mg paclitaxel was administered. Five minutes after the paclitaxel infusion, he developed anaphylactic shock(More)
