title: [Obsessive-compulsive disorders in children. Subtypes of OCD and their relation to infection with group A streptococci].
abstract: The present review describes the theory of a spectrum of obsessive-compulsive disorders (OCD). This spectrum includes such disorders as trichotillomania, eating disorders, body dysmorphic disorder, and possibly pervasive developmental disorders. OCD with an onset in childhood is presented as a specific subtype, with more boys affected and frequently co-morbid with tics and Tourette's syndrome. Furthermore, it seems to be more genetically determined and have more significant deviations, as measured by neuro-imaging studies, than has OCD with an adult onset. The PANDAS theory (paediatric autoimmune neuropsychiatric disorder associated with streptococcal infections) is described. This subtype of OCD is, still on a speculative basis, connected to infections with beta-haemolytic streptococci. The obsessive-compulsive symptoms are characterised by a sudden onset, "sawtoothed" course with relapses and remissions, and are associated with neurological abnormalities. There are still no clinical consequences in terms of penicillin treatment of this PANDAS subtype of OCD.
