Are family history of psoriasis , stressful life events , and recent infectious disease risk factors for a first episode of acute guttate psoriasis : results of a case-control study?
The study confirmed that recent pharyngeal infection is a risk factor for guttate psoriasis. It also documented the strong association between guttate psoriasis and a family history of psoriasis. Finally, the study added evidence to the belief that stressful life events may represent risk factors for the onset of psoriasis. By relying on the clinical diagnosis we possibly underestimate the association of guttate psoriasis with infection.
Birth origin thus impacts the development of atypical ethologically-defined behavioural profiles, reminiscent of certain depressive-like symptoms. The use of unbiased behavioural observations might allow the identification of animal models of human mental/behavioural disorders and their most appropriate control groups.
