Case Reports
A case of rectal Dieulafoy's lesion successfully treated by transcatheter arterial embolization.
A 50-year-old man showed massive lower gastrointestinal bleeding without a triggering episode. An emergency colonoscopy revealed a protruding vessel in the lower rectum with no active bleeding. No underlying ulcer was seen within the surrounding mucosa. ⋯ During the second angiography, sudden bleeding occurred. Angiography showed extravasation of contrast medium from the distal branch of the superior rectal artery. Transcatheter arterial embolization was performed, and was very effective.

The use of post-mortem radiological imaging is becoming increasing widespread in forensic medicine. These images can help improve the quality and safety of autopsy. ⋯ Autopsy showed that both artifacts were pieces broken off of a sharp instrument. Some possible benefits of postmortem MSCT include the ability to reconstruct visual images of weapons and the possible prevention of injury to autopsy personnel.

The purpose of this study was to determine the features of chest computed tomography (CT) in children with swine-origin influenza A (H1N1) virus (S-OIV). ⋯ Multifocal consolidation with central distribution is a common CT finding in children with S-OIV, but there are few GGO-dominant cases. Widespread consolidation (segmental or lobar) is also common.

The aim of this study was to evaluate the influence of passive maternal smoking on blood flow velocities in arteries of the fetal-placental-maternal circulation. ⋯ Effects of passive maternal smoking on the fetal-placental-maternal unit were comparable to those with active maternal smoking as determined by the means of increased resistance in the maternal vasculature and adaptive changes of cerebroplacental circulation for maintaining fetal cerebral circulation.

Comparative Study
Newly developed compression fractures after percutaneous vertebroplasty: comparison with conservative treatment.
The aim of this study was to investigate the incidence and timing of subsequent fractures in patients treated with and without percutaneous vertebroplasty (PVP). ⋯ PVP did not increase the incidence of new compression fractures compared with conservative treatment, but half of the new fractures at the adjacent vertebral bodies occurred sooner.
