background: hepatitis b virus potentially accelerates graft rejection and mortality in renal transplantation population. vaccination of graft candidates without prior immunization against hbv seems essential before transplantation but some candidates of transplantation have not received hbv vaccine at the time of receiving graft. we aimed to evaluate immunogenicity of an enhanced regimen (4 dos...

BACKGROUND Previous experimental studies have been conducted to evaluate the biomechanical effects of posterior cruciate ligament reconstruction; but no consensus has been reached on the preferred method of reconstruction. METHODS The 3D finite element mesh of a knee joint was reconstructed from computed tomography and magnetic resonance images. The ligaments were considered as hyperelastic m...

We report herein improved methods for the safe and successful completion of endoscopic papillectomy (EP). Between January 2008 and November 2011, 12 patients underwent double-snare retracting papillectomy for the treatment of lesions of the major duodenal papilla. The main outcomes were en bloc resection rates, pathological findings, and adverse events. All of the patients (mean age, 60.1 years...

BACKGROUND The tensile force applied to an anterior cruciate ligament graft determines the maximal anterior translation; however, it is unknown whether the tensile force is transferred to the intra-articular portion of the graft and whether the intra-articular tension and maximal anterior translation are maintained shortly after ligament reconstruction. METHODS Ten cadaveric knees were recons...

Recent biomechanical studies have shown that an anatomic double-bundle posterior cruciate ligament (PCL) reconstruction is superior in restoring normal knee laxity compared with the conventional single-bundle isometric reconstruction. We describe a modification of an endoscopic PCL reconstruction technique using a double-bundle Y-shaped hamstring tendon graft. A double- or triple-bundle semiten...

BACKGROUND The efficacy of using a double-bundle versus single-bundle graft for posterior cruciate ligament reconstruction has not been demonstrated. HYPOTHESIS A double-bundle graft restores knee kinematics better than a single-bundle graft does in tibial inlay PCL reconstructions. STUDY DESIGN Controlled laboratory study. METHODS Eight cadaveric knees were subjected to 6 cycles from a 4...

Introduction: It is important to preserve epithelial and connective tissue attachment at its original level after periapical surgery. The aim of this study was to compare the periodontal parameters after using the papilla base flap and the sulcular full-thickness flap procedures. Methods: Fourteen healthy patients with no periodontal disease referred for surgical treatment of periapical lesions...

Two hundred forty interdental papilla sites in 20 healthy patients were investigated. Interdental papilla heights of maxillary anterior teeth were measured from the gingival zenith, along with clinical crown lengths. Percentages of papilla height to crown length were computed and defined as papilla proportion, mesial papilla proportion (MPP), and distal papilla proportion (DPP). Mean interdenta...

BACKGROUND Posterior Cruciate Ligament (PCL) ruptures are common sports injuries. One of the key controversies in PCL reconstruction is whether double-bundle reconstruction provides biomechanical and clinical outcomes superior to single-bundle reconstruction. METHODS We performed a comprehensive search in multiple databases to evaluate the advantages of single-bundle or double bundle reconstr...
