Due to latency periods that can last for decades, asbestos-related diseases show 18 years after the enforcement of the prohibition of asbestos application in Germany their highest numbers. In the centre of attention are asbestos-induced pleural fibroses, mesotheliomas, asbestoses, lung and laryngeal cancer. Diagnosing and expertizing these diseases causes difficulties, is hitherto non-uniform and does frequently not correspond to the current medico-scientific expertise. This induced the German Respiratory Society as well as the German Society of Occupational and Environmental Medicine in cooperation with the German Society of Pathology, the German Radiology Society and the German Society of Otorhinolaryngology, Head and Cervical Surgery, to develop the above mentioned guideline during seven meetings moderated by AWMF. The required thorough diagnosis is based on the detailed recording of a qualified occupational history. Since the sole radiological and pathological-anatomical findings cannot sufficiently contribute to the causal relationship the occupational history recorded by a general physician and a specialist is of decisive importance. These physicians have to report suspected occupational diseases and to advise patients on social and medical questions. Frequently, problems occur if the recognition of an occupational disease is neglected due to a supposedly too low exposure or too few ferruginous bodies or low fibre concentrations in lung tissue. The new S2k directive summarizing the current medico-scientific knowledge is for this reason, for diagnoses and expert opinions as well as for the determination of a reduced capacity for work a very important source of information.
