Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most serious adverse event of ERCP. Therefore, it important to identify high-risk patients who require prophylactic measures. The aim this study was develop a practical prediction model for PEP that identifies patients.Patients underwent ERCP at three tertiary hospitals between April 2010 and September 2012 were enrolled. dataset divided into training set (two centers) validation (one center). Using set,...

Despite increased risk for coronary artery disease and acute myocardial infarction (AMI), prior studies have found that smokers with AMI lower mortality rates than nonsmokers, a phenomenon often termed 'smoker's paradox'. The present study was designed to examine the etiology of paradox', especially respect association inflammation. subjects included 528 consecutive patients who were admitted within 24 hours onset underwent successful intervention. Of subjects, 232 (44%) smokers. cardiac...

Whether young cervical cancer patients have poorer prognosis compared to older ones has remained controversial over the past half century. The last three decades seen a rise in morbidity and mortality among Japanese women with cancer. This reflects fact that importance of prevention not been fully recognized due limited clinical studies. We examined relationship between age cancer.We retrospectively medical records consecutive International Federation Gynecology Obstetrics stage IB IIB at...

The predictors of cardiac rupture (CR) in patients with acute myocardial infarction (AMI) treated successful primary coronary angioplasty have not been identified.Of 433 consecutive AMI subjects who underwent reperfusion by within 24 h onset, CR occurred 11 (2.5%), free wall 9, and ventricular septal perforation 2. Rates females, diabetes mellitus anterior were higher the group than others (p < 0.05). There no significant differences between 2 groups terms left (LV) function soon after...

Pancreatic metastases (PMs) account for 1% to 2% of pancreatic tumors, and their prognostic significance is poorly defined. We evaluated the incidence clinical characteristics primary tumors defined factors.This retrospective study 39 Japanese tertiary referral hospitals (January 2005 August 2015) analyzed patient tumor survival time. Kaplan-Meier analysis Cox proportional hazards models were applied evaluate overall factors, respectively.We enrolled 159 patients with a pathologic diagnosis...

Some colorectal cancer patients harboring FGFR (fibroblast growth factor receptor) genetic alterations, such as copy number gain, mutation, and/or mRNA overexpression, were selected for enrollment in several recent clinical trials of inhibitor, because these alterations preclinically reported to be associated with inhibitor sensitivity well poor prognosis, invasiveness, metastatic potential. However, few enrolled responsive inhibitors. Thus, practical strategies are eagerly awaited that can...

Trigeminal neuralgia (TN) occasionally affects older adults, frequently worsens, and becomes refractory to medication. Older adult patients with TN may consider microvascular decompression (MVD) for their treatment. No study examines MVD effects on patients' health-related quality of life (HRQoL). The present evaluates the HRQoL aged 70 years before after MVD.Adult who underwent evaluated using 36-Item Short-form (SF-36) Health Survey 6 months MVD. were divided into four groups according...
