In this study 112 end-stage renal disease patients on hemodialysis were analyzed for their state of well-being, cognition, ambulatory capacity, and dexterity. The Nottingham Health Profile, the locomotion and dexterity sections of the Office of Population Censuses and Surveys disability scale, the modified Mini Mental State examination and a weighted index of comorbidity were used for assessment. The study revealed that good cognition, good mood, young age, and milder comorbid conditions were positively linked with good functional levels of locomotion and dexterity. The test instruments used in the investigation were considered simple to use and were effective in revealing relationships between the above-mentioned parameters.
Various malignant tumors of the liver, especially liver angiosarcoma, have been described after occupational exposure to vinyl chloride monomer. We present the case records and pathologic findings of two plastic industry workers who had been exposed to high concentrations of vinyl chloride. These workers developed hepatic neoplasms, angiosarcoma, or hemangiopericytoma. We discuss the histogenesis of these tumors; the common vascular origin and the mutual transformation of these two tumors suggest that the hemangiopericytoma may also have developed during occupational exposure to high concentrations of vinyl chloride monomer.
