ABSTRACT

BACKGROUND: Psoriasis is a hyperproliferative, cutaneous disorder with the potential to lower levels of folate. This may result in raised levels of homocysteine, an independent risk factor for the development of cardiovascular disease. OBJECTIVE: A study was conducted to compare levels of red-cell folate (RCF) and homocysteine in patients with psoriasis and in healthy controls. Levels of homocysteine were also examined in the context of other major cardiovascular risk factors. METHODS: In total, 20 patients with psoriasis and 20 controls had their RCF, homo-cysteine and other conventional cardiovascular risk factors assessed. RESULTS: Patients with psoriasis had a trend towards lower levels of RCF. Significantly raised levels of homocysteine were found in patients with psoriasis compared with controls (P = 0.007). There was no correlation between homocysteine levels, RCF levels or disease activity as measured by the Psoriasis Area and Severity Index. Patients with psoriasis had higher body mass index (P < 0.004) and higher systolic blood pressure (P < 0.001) than controls. This may contribute to the excess cardiovascular mortality observed in patients with psoriasis.

ABSTRACT

BACKGROUND: It has been established internationally that road traffic accidents (RTAs) involving older drivers follow clearly different patterns of timing, location and outcomes from those of younger age groups. Older pedestrians are also a vulnerable group and fewer analyses have been undertaken of the phenomenology of their injuries and fatalities. We studied the pattern of pedestrian RTAs in Ireland over a five-year period with the aim of identifying differences between older pedestrians (aged 65 or older) and younger adults. METHODS: We examined the datasets of the Irish National Road Authority (now the Road Safety Authority) from 1998-2002. We analysed patterns of crashes involving older pedestrians (aged 65) and compared them with younger adults (aged 18-64). RESULTS: Older people represented 36% (n = 134) of pedestrian fatalities and 23% of serious injuries while they only account for 19% of total RTAs. Mortality in RTA is more than doubled for older pedestrians compared to younger adults (RR 2.30). Most accidents involving older pedestrians happen in daylight with good visibility (56%) and in good weather conditions (77%). CONCLUSIONS: Older pedestrians are particularly vulnerable in RTAs. These occur more frequently during daylight hours and in good weather conditions. This may point to a need for prevention strategies that are targeted at the traffic environment and other road users rather than at older people.
