The CIAOW study (Complicated intra-abdominal infections worldwide observational study) is a multicenter underwent in 68 medical institutions during six-month period (October 2012-March 2013). included patients older than 18 years undergoing surgery or interventional drainage to address complicated (IAIs). 1898 with mean age of 51.6 (range 18-99) were enrolled the study. 777 (41%) women and 1,121 (59%) men. Among these patients, 1,645 (86.7%) affected by community-acquired IAIs while...

To determine the value of high-resolution computed tomography (HRCT) in diagnosis diffuse pulmonary diseases, a direct HRCT-pathologic correlative study was performed using four inflated and fixed lungs from autopsy. In normal lungs, smallest artery resolved by HRCT 200 microns diameter; accompanied terminal bronchiole first-order respiratory bronchiole. The distance vessel to corresponding lobular border ranged 3 5 mm. These results suggest that centrilobular area or around bronchioles can...

Coronary heart disease incidence and mortality remain very low in Japan despite major dietary changes increases risk factors that should have resulted a substantial increase coronary rates (Japanese paradox). Primary genetic effects are unlikely, given the Japanese migrating to United States. For men aged 40–49 years, levels of total cholesterol blood pressure been similar States throughout their lifetimes. The authors tested hypothesis subclinical atherosclerosis, artery calcification,...

Usefulness of high-resolution computed tomography (HRCT) in locating pulmonary parenchymal disease relation to the lobule was evaluated 71 patients, including 30 with normal parenchyma and 41 various diseases. Both 10-mm-thick sections 1.5- or 3.0-mm-thick HRCT scans were obtained. Distribution classified as centrilobular, panlobular, perilobular, bronchovascular, nonlobular. Intralobular classification distribution more feasible less severely diseased regions. revealed thickened...

Despite advances in diagnosis, surgery, and antimicrobial therapy, mortality rates associated with complicated intra-abdominal infections remain exceedingly high. The World Society of Emergency Surgery (WSES) has designed the CIAOW study order to describe clinical, microbiological, management-related profiles both community- healthcare-acquired a worldwide context. (Complicated Intra-Abdominal infection Observational Worldwide Study) is multicenter observational currently underway 57 medical...

To compare lung nodule detection performance (LNDP) in computed tomography (CT) with adaptive iterative dose reduction using three dimensional processing (AIDR3D) between ultra-low CT (ULDCT) and low (LDCT).This was part of the Area-detector Computed Tomography for Investigation Thoracic Diseases (ACTIve) Study, a multicenter research project being conducted Japan. Institutional Review Board approved this study informed consent obtained. Eighty-three subjects (body mass index, 23.3 ± 3.2)...

To describe the MR appearance of normal appendix and imaging characteristics acute appendicitis with correlation to pathological severity.A total 20 volunteers participated in this study demonstrate appendices by imaging. A 37 consecutive patients clinically diagnosed were also scanned. T1-weighted (T1WI) spin-echo images, T2-weighted (T2WI) fast spin-echo, fat-suppressed spectral presaturation inversion recovery (T2SPIR) images obtained. The criteria for considering as follows: 1)...

The image quality of a newly developed full-field digital phase contrast mammography (PCM) system and conventional screen-film (SF) were compared via images phantom receiver operating characteristic (ROC) analysis clinical images.Magnified (1.75X) PCM scanned (sampling rate, 43.75 microm) then reduced to original-sized, 25-micron pixel printed on photothermographic film. Along with corresponding SF images, the evaluated subjectively, 38 patients subjected ROC mass microcalcification.In...

To evaluate the use of cine-magnetic resonance imaging (MRI) with a steady-state free precession sequence to monitor and assess small bowel motility.Sequential MRI, using balanced sequence, was performed in eight healthy male volunteers at 0, 15, 30, 45, 60 minutes after oral administration 1500 mL nonabsorbable fluid contractions. Using cine-mode display, contractions were reviewed luminal diameter measured on each image obtain frequency amplitude contractions.The preparation well tolerated...

Sodium-glucose cotransporter 2 inhibitors reduce bodyweight (BW) by creating a negative energy balance. Previous reports have suggested that this BW reduction is mainly loss of body fat and ~20% the lean mass. However, effects sodium-glucose on composition remain unclear. We examined these in Japanese patients with type diabetes mellitus treated insulin.In open-label, randomized controlled trial, 49 overweight (body mass index ≥23 kg/m2 ) inadequate glycemic control (hemoglobin A1c >7.0%)...
