Cataract prevalence increases with age. As the world's population ages, cataract-induced visual dysfunction and blindness is on the increase. This is a significant global problem. The challenges are to prevent or delay cataract formation, and treat that which does occur. Genetic and environmental factors contribute to cataract formation. However, reducing ocular exposure to UV-B radiation and stopping smoking are the only interventions that can reduce factors that affect the risk of cataract. The cure for cataract is surgery, but this is not equally available to all, and the surgery which is available does not produce equal outcomes. Readily available surgical services capable of delivering good vision rehabilitation must be acceptable and accessible to all in need, no matter what their circumstances. To establish and sustain these services requires comprehensive strategies that go beyond a narrow focus on surgical technique. There must be changes in government priorities, population education, and an integrated approach to surgical and management training. This approach must include supply of start-up capital equipment, establishment of surgical audit, resupply of consumables, and cost-recovery mechanisms. Considerable innovation is required. Nowhere is this more evident than in the pursuit of secure funding for ongoing services.
BACKGROUND: Several prostate cancer (PCa) susceptibility loci have been reported, but attempts to confirm them in independent data sets have produced inconsistent results. It is not yet clear, how much of this variation is due to differences between different populations. HPCX was originally identified in a combined data set of PCa families from the USA and Scandinavia. Considerable differences in the frequency of linked families were observed in this heterogeneous family sample as well as in following studies. METHODS: In order to estimate the significance of HPCX in the German population, DNA samples from 104 PCa families were genotyped at six polymorphic markers spanning a region of approximately 14 cM on Xq27-28, which includes the proposed HPCX candidate locus. RESULTS: In the entire data set, a maximum NPL Z score of 1.20 (P = 0.11) at marker DXS984 was observed. Statistically significant evidence for linkage was obtained in the subset of 63 families with early-onset disease (i.e., < or = 65 years) with a maximum NPL Z score of 2.32 (P = 0.009) at the same location. CONCLUSION: Our results confirm the existence of a prostate cancer susceptibility gene on Xq27-28 also in the German population.
