The outcomes of transanal endorectal pull-through for Hirschsprung's disease according to the mucosectomy-commencing points: A study based on the results of a nationwide survey in Japan.

Background/aim: Although the mucosectomy-commencing points on transanal endorectal pull-through (TAEPT) differ among reports, the optimal point is unclear. This study assessed the outcomes among different mucosectomy-commencing points.

Methods: We conducted a nationwide survey from 2008 to 2012.

Nationwide survey of outcome in patients with extensive aganglionosis in Japan.

Purpose: Hirschsprung's disease-related short bowel syndrome (HDSBS) is characterized by aganglionosis that extends orally to 75 cm from Treitz's band. The condition is reported be associated with a high mortality rate of 50-80%. This retrospective study aimed to survey the current trends in HDSBS treatment in Japan.

Personal Authentication Analysis Using Finger-Vein Patterns in Patients with Connective Tissue Diseases--Possible Association with Vascular Disease and Seasonal Change.

Objective: To examine how connective tissue diseases affect finger-vein pattern authentication.

Methods: The finger-vein patterns of 68 patients with connective tissue diseases and 24 healthy volunteers were acquired. Captured as CCD (charge-coupled device) images by transmitting near-infrared light through fingers, they were followed up in once in each season for one year.

Near-infrared finger vein patterns for personal identification.

We have demonstrated a personal identification system that is based on near-infrared finger vein patterns. Finger vein patterns of 678 volunteers are acquired by transmitting near-infrared light through a finger and capturing the image with a CCD camera. These vein patterns are enhanced by a background-reduction filter.
