Background: From

BackgroundFor years the Robert Koch Institute (RKI) has been annually pooling and reviewing the data from the German population-based cancer registries and evaluating them together with the cause-of-death statistics provided by the statistical offices. Traditionally, the RKI periodically estimates the number of new cancer cases in Germany on the basis of the available data from the regional cancer registries in which registration is complete; this figure, in turn, forms the basis for further important indicators.MethodsThis article gives a brief overview of current indicators - such as incidence, prevalence, mortality, survival rates - on the most common types of cancer, as well as important ratios on the risks of developing and dying of cancer in Germany.ResultsAccording to the latest estimate, there were a total of 436,500 new cancer cases in Germany in 2004. The most common cancer in men is prostate cancer with over 58,000 new cases per annum, followed by colorectal and lung cancer. In women, breast cancer remains the most common cancer with an estimated 57,000 new cases every year, also followed by colorectal cancer. These and further findings on selected cancer sites can be found in the current brochure on "Cancer in Germany", which is regularly published by the RKI together with the Association of Population-based Cancer Registries in Germany (GEKID). In addition, the RKI made cancer-prevalence estimates and calculated current morbidity and mortality risks at the federal level for the first time. According to these figures, the 5-year partial prevalence - i.e. the total number of cancer patients diagnosed over the past five years who are currently still living - exceeds 600,000 in men; the figure is about the same among women. Here, too, the most common cancers are prostate cancer in men and breast cancer in women. The lifetime risk of developing cancer, which is more related to the individual, is estimated to be higher among men (48.5%) than among women (40.3%). In roughly rounded figures, therefore, about every second person in Germany develops cancer in the course of their lives. One in four men and one in five women die of cancer.ConclusionsIn recent years, population-based cancer registration in Germany has come significantly closer to the aim of the complete, nationwide coverage of cancer. The continuous improvements in the data situation help describe cancer development in Germany.

ABSTRACT.Purpose: To study and classify retinal lesions in patients with birdshot disease using wide-field autofluorescence imaging and correlate them according to patients' visual status. Methods: A multicentre study was carried out on 76 eyes of 39 patients with birdshot disease, analysing colour images and under autofluorescence using the wide-field Optomap â imaging system. This was combined with a complete clinical exam and analysis of the macula with OCT. Results: In over 80% of the eyes, a chorioretinal lesion has been observed under autofluorescence with a direct correlation between the extent of the lesion and visual status. The presence of macular hypo-autofluorescence was correlated with a decreased visual acuity, due to the presence of a macular oedema, active clinical inflammation or an epiretinal membrane. The hypo-autofluorescence observed correlated with the duration of the disease and the degree of inflammation in the affected eye, indicating a secondary lesion in the pigment epithelium in relation to the choroid. The pigment epithelium was affected in a diffuse manner, as in almost 50% of the eyes the wider peripheral retina was affected. Conclusion: Wide-field autofluorescence imaging could appear to be a useful examination when monitoring patients, to look for areas of macular hypoautofluorescence responsible for an irreversible loss of vision.

The German Environmental Survey for Children (GerES IV) is the environment-related module of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) of the Robert Koch Institute and the fourth GerES of the Federal Environment Agency. The main objective of GerESs is to analyse and document the extent, distribution and determinants of exposure to environmental pollutants of the German general population. GerES IV was performed from 2003 to 2006. A total of 1.790 children aged 3-14 years from 150 sampling locations participated in GerES IV. Samples of blood, urine, tap water, house dust and indoor air were analysed. Hearing tests, measurements of traffic noise and interviews to get exposure-related information were conducted. First results indicate a clear decrease of the exposure to arsenic, lead and mercury. Cotinine concentrations in urine can be used to classify the exposure of children to environmental tobacco smoke. The examination of the tap water used in the subjects' households indicates that in some households the guideline values of the German Drinking Water Ordinance were not always met. This is the case for nickel, copper and lead which are used as pipe material for domestic plumbing.
