[Ulcerative colitis complicated by pyoderma gangrenosum and multiple aseptic abscesses].

A woman in her 30s was diagnosed with ulcerative colitis (UC) 4 years ago and treated with tacrolimus, azathioprine, and prednisolone 5mg (PSL). Skin ulcers appeared on the right lower leg during the course of treatment, diagnosed as pyoderma gangrenosum (PG). The patient initially improved with an increased PSL and infliximab dose, but then developed multiple skin ulcers and folliculitis throughout her body.

Efficacy of using red dichromatic imaging throughout endoscopic submucosal dissection procedure.

Background: Management of bleeding during endoscopic submucosal dissection (ESD) is critical. Red Dichromatic Imaging (RDI), a novel image-enhanced endoscopy technology, has been reported to improve the visibility of deep vessels and bleeding source compared to white light imaging (WLI). We hypothesized that using RDI during the entire cutting process (full time RDI ESD: FTR-ESD), higher R0 resection rate, shorter procedure time and fewer complications could be achieved.

The distribution and function of aquaporins in the kidney: resolved and unresolved questions.

The membrane water channel aquaporin (AQP) family is composed of 13 isoforms in mammals, eight of which are reportedly expressed in the kidney: AQP1, 2, 3, 4, 6, 7, 8, and 11. These isoforms are differentially expressed along the renal tubules and collecting ducts. AQP1 and 7 are distributed in the proximal tubules, whereas AQP2, 3, and 4 occur in the collecting duct system.
