Cerebral blood flow abnormalities with central sparing on arterial spin labeling in mild encephalopathy associated with excitotoxicity: a case report.

Background: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and mild encephalopathy associated with excitotoxicity (MEEX) are the most frequent acute encephalopathies in pediatric patients in Japan. AESD typically presents with biphasic seizures and delayed reduced diffusion in the subcortical area, called bright tree appearance (BTA), on radiological examination. In patients with AESD, arterial spin labeling (ASL) shows decreased cerebral blood flow (CBF) in the hyperacute stage and increased CBF in the acute stage, suggesting the usefulness of ASL for the early diagnosis of AESD.

Echogenicity in transrectal ultrasound is determined by sound speed of prostate tissue components.

Typically, conventional transrectal ultrasound (TRUS) imaging of the cancer tissue is hypoechoic in echo texture. However, TRUS does not reliably distinguish between cancerous and non-cancerous tissue in the prostate. In the present study, sound speed of prostate needle biopsy specimens were measured by ultrasound speed microscope (USM) to construct a database for interpreting clinical TRUS images.

Ultrasonic tissue characterization of prostate biopsy tissues by ultrasound speed microscope.

Ultrasound speed microscope was developed for quantitative measurement of ultrasonic parameters of soft tissues. The system can measure the ultrasonic attenuation and sound speed in the tissue using fast Fourier transform of a single pulsed wave instead of burst waves used in conventional acoustic microscopy. Prostate biopsy tissues were formalin-fixed and sectioned approximately 5-6 μm in thickness.

New cystoscopic diagnosis for interstitial cystitis/painful bladder syndrome using narrow-band imaging system.

Objectives: Diagnosing the bladder lesions associated with interstitial cystitis/painful bladder syndrome (IC/PBS) is sometimes difficult for general urologists. We therefore aimed to develop an IC/PBS diagnosis method using a cystoscope with a narrow-band imaging (NBI) system that can detect mucosal angiogenic lesions.

Methods: Fifty-two subjects suspected of having IC between October 2006 and June 2007 were included in this study.

[One-year experience of Men's Outpatient Health Care Unit without specifying the category of disease].

The Men's Outpatient Health Care Unit was established in April 2006 in Kyoto City Hospital. In this outpatient unit, medical services are provided to males of all ages and with any category of complaints. For patients' privacy, the unit is situated on a different floor from the other outpatient ward, and all-male staff handles from reservation to examination.
