[Sick building syndrome should be treated more from a reasonable than an evidence-based point of view]

During the past decades, several non-specific syndromes have gradually appeared and eventually been given generic denominations such as "diseases of modern life". One of these is the so called Sick Building Syndrome (SBS), which consists of various combinations of common, non-specific symptoms as well as an absence of signs demonstrable by laboratory tests and other medical examinations or means. The lack of demonstrable biological correlates together with vague etiologic attributions make it unusually problematic to study, resulting in the production of a general, non-specific and sometimes contradictory fund of knowledge. This often transforms instances of SBS to theaters of conflict people by parties with divergent interests. Technical/scientific expertise can provide general advice but not unambiguously contribute to the resolution of the conflicts.
