Appropriate imaging utilization in Japan: a survey of accredited radiology training hospitals.

Purpose: To survey whether imaging is being performed appropriately in Japan, and to survey whether radiologists intervene to ensure imaging requests are appropriate.

Methods: An online survey was sent to radiologists at accredited radiology training hospitals. The survey included the radiologists' perspectives on whether imaging is performed appropriately at their institutions and whether they intervene if the indication for imaging is inappropriate/ambiguous.

[Diseases and procedures apt to conflict with patients: an analysis of medical malpractice litigation cases].

The aim of this study was to explore effective ways to prevent conflicts between patients and healthcare professionals by analyzing 836 malpractice cases. The analysis revealed two points that especially influence court decisions: disease prognosis and inadequate informed consent. Regarding prognosis, decisions are more in favor of the defendant (medical institution) in diseases with poor prognoses, such as sepsis and anaphylaxis, than in diseases with typically good prognoses, such as acute epiglottitis and strangulation ileus.

[Pitfalls in informed consent: a statistical analysis of malpractice law suits].

In medical malpractice law suits, the notion of informed consent is often relevant in assessing whether negligence can be attributed to the medical practitioner who has caused injury to a patient. Furthermore, it is not rare that courts award damages for a lack of appropriate informed consent alone. In this study, two results were arrived at from a statistical analysis of medical malpractice law suits.

MRGX is a novel transcriptional regulator that exhibits activation or repression of the B-myb promoter in a cell type-dependent manner.

MRGX is a novel transcription factor that is a member of the mortality factor 4 (MORF4)-related gene family. MRG15, a closely related family member, is in a complex with the retinoblastoma tumor suppressor protein Rb and activates the B-myb promoter, which is tightly controlled by Rb/E2F through the E2F binding site. In this study we investigated the effect of MRGX on the B-myb promoter.

MR microscopy of articular cartilage at 1.5 T: orientation and site dependence of laminar structures.

Objective: To evaluate MR microscopic images of normal-appearing porcine hyaline cartilage ( n=15) in vitro obtained with an MR microscope using an independent console system (MRMICS) at 1.5 T.

Design And Results: The MRMICS is a portable imaging system consisting of a radiofrequency system, gradient power supplies and a personal computer.
