It necessary examine trend occurrence surveillance KD.The patient 2015 2016 conducted 2017, as 24th KD. A questionnaire sent pediatric departments hospitals with >100 beds specialized hospitals, responded by attending...

Abstract Background Distal radius fracture (DRF) is very common worldwide. In particular, aging countries have numerous patients with DRF, resulting in an urgent need for active preventive measures. As few epidemiological studies investigated DRF Japan, we aimed to identify the characteristics of all ages Japan. Methods This descriptive epidemiologic study analyzed data obtained from clinical information diagnosed January 1, 2011, December 31, 2020, at a prefectural hospital Hokkaido, We...

Arterio-enteric fistulas (AEFs) are a rare cause of gastrointestinal bleeding involving direct communication between an artery and the intestinal tract. The duodenum is most common fistula site for AEFs, but none rectal cases known. We present case elderly man with hematochezia due to caused by left internal iliac aneurysm, which was detected on contrast-enhanced computed tomography (CT), showing typical formation ectopic gas images.

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder that, according to the most well accepted hypothesis (1), caused by replicating, transmissible, abnormal forms of host-encoded prion protein (prions). Most CJD cases occur spontaneously (sporadic CJD) or are inherited (genetic CJD). Iatrogenic can after exposure prion-contaminated instruments products in medical/surgical settings. Cadaveric dura mater graft-associated (dCJD) accounts for common form iatrogenic CJD. This...

Since 1987, no study has reported the municipal-level geographical clustering of Kawasaki disease (KD) in Japan. Therefore, aim present was to identify temporal and KD.The annual incidence rates KD for each municipality were calculated using nationwide data from 73 758 patients with (2007-2012). To determine whether existed, we correlations during years, compared these those adjacent municipalities. Spatial scanning analysis used clusters year, surrounding region.The national rate KD,...
