Bortezomib, an effective anticancer drug for multiple myeloma, often causes peripheral neuropathy which is mainly characterized by numbness and painful paresthesia. Nevertheless, there is no effective strategy to escape or treat bortezomib-induced peripheral neuropathy (BIPN), because we have understood few mechanism of this side effect. In this study, we evaluated behavioral and pathological characteristics of BIPN, and investigated pharmacological efficacy of various analgesic drugs and adjuvants on mechanical allodynia induced by bortezomib treatment in rats.

Background And Aims: The age distribution of patients with hepatocellular carcinoma (HCC) now peaks at nearly 70 years in Japan and this is continually increasing. Whether such elderly patients with HCC aged 80 years or older should be treated, and if so, how they should be selected for treatment remains uncertain. The present study was undertaken to determine any differences in the clinical characteristics and prognostic features between patients with HCC aged 80 years or older and those younger than 80 years of age.

Background/aims: Whether or not generalists and specialist physicians can make an appropriate adaptation of their practice patterns when caring for their patients currently remains a matter of debate. The present study was undertaken to explore whether the clinical characteristics of hepatocellular carcinoma at its time of detection, the initial treatment options and the survival vary between patients with hepatocellular carcinoma associated with cirrhosis who were treated by hepatologists and those who were treated by non-hepatologists.

Methodology: A retrospective study with 626 patients with hepatocellular carcinoma associated with cirrhosis was performed.

We used color Doppler ultrasonography (US) to evaluate bowel wall thickening in ulcerative colitis and to determine the value of this modality in this application. Twelve patients (6 men and 6 women) with ulcerative colitis underwent both gray-scale and color Doppler US. Bowel wall thickness and wall echotexture were recorded by gray-scale US, and the presence of intramural color Doppler flow and arterial signal were evaluated by color Doppler US.
