A review of assistive technologies for people with Parkinson's disease.

The population is aging and with this, the incidence of age related diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD) are increasing. Assistive Technology (AT) is viewed as one of the possible solutions which can be used to meet the needs of persons suffering from PD. AT can enable a person to carry out a task which otherwise they would be unable to undertake independently. An AT can have many functions which range from helping people to use a computer, to monitoring someone's condition. Within this paper we attempt to categorize the different types of AT for persons with PD. Each of the technologies will be compared and contrasted and an overview of what is currently available presented. The paper concludes with some visionary comments on how the current levels of AT may change in the future.

Polymorphisms in the interleukin 10 gene promoter are associated with susceptibility to aggressive non-Hodgkin's lymphoma.

Interleukin-10 (IL-10) is mainly an anti-inflammatory cytokine produced by a number of cells including normal and neoplastic B cells. It has been implicated in autoimmunity, transplantation tolerance and tumourigenesis. Polymorphisms in the IL-10 gene promoter genetically determine inter-individual differences in IL-10 production. The aim of this study was to determine whether polymorphisms in the IL-10 gene promoter play a role in predisposing an individual to lymphoma. We analysed the frequencies of three single base substitutions in the IL-10 promoter in patients with aggressive lymphoma (B-cell DLCL n = 46, other aggressive histologies n = 17), Hodgkin's disease (n = 44) or low/intermediate grade lymphoma (n = 46), compared to healthy controls. The frequency of the low-IL-10 producing AA allele (at position -1082) was significantly higher in patients with aggressive lymphoma compared to controls (p = 0.0344, Odds ratio 1.974, 95% C.I 1.066-3.655). Similarly, the frequency of the low IL-10 producing ATA or the intermediate-IL-10- producing ACC haplotype was significantly higher in patients with aggressive disease compared to controls (p = 0.0255, Odds ratio 1.647, 95% C.I 1.077-2.518). No association was found between IL-10 genotypes and Hodgkin's disease or less aggressive forms of lymphoma. Thus, polymorphisms in the IL-10 gene promoter which are associated with a low IL-10 producing phenotype may influence susceptibility to aggressive forms of lymphoma or may contribute to the pathogenesis of this disease.
