Profile of patients consulting in child psychiatry for trichotillomania

Résumé

Introduction Trichotillomania is a disorder characterized by the compulsive pulling out of one’s own hair. It usually starts just before or after puberty, and about 1 to 2% of people have this disorder. But its incidence is variable over the years and socio-demographic data. Objectives Describe the profile of children and adolescents consulting for trichotillomania. Methods An incidence survey was carried out among children and adolescents followed for trichotillomania at the out-patient unit of child psychiatry (Monastir - Tunisia) from January 2003 to September 2020. Results Among the 11000 patients who were followed during the study period, 47 patients presented trichotillomania, corresponding to a rate of 0.42%. Three of them presented with associated trichophagia and two were operated on in pediatric surgery for trichobezoar. A female predominance was noted with a sex-ratio of 0.37. The average age was 9.3 years with extremes ranging from 2 to 15 years. Almost all of the patients were in school. Most of the patients were referred by dermatologists. We retained in these patients: 17% presented an attachment disorder, 14.8% had a depressive disorder, 6.3% had anxiety elements, 6.3% had an intellectual disability, 4.2% had an associated enuresis and one case had a GAD. The treatment was to undergo behavioral measurements or CBT in 91.4%. Pharmacological management was carried out in 46.8% of patients and was mainly based on antidepressants. Conclusions Trichotillomania is a disorder that can be stressful for patients as well as their families. Better knowledge of the profile of these patients is necessary in order to better therapeutic efficacy.
