Trichotillomania is more related to Tourette disorder than to obsessive-compulsive disorder

Objective: Trichotillomania (TTM) is characterized by the pulling out of one's hair. TTM was classified as an impulse control disorder in DSM-IV, but is now classified in the obsessive-compulsive related disorders section of DSM-5. Classification for TTM remains an open question, especially considering its impact on treatment of the disorder. In this review, we questioned the relation of TTM to tic disorder and obsessive-compulsive disorder (OCD). Method: We reviewed relevant MEDLINE-indexed articles on clinical, neuropsychological, neurobiological, and therapeutic aspects of trichotillomania, OCD, and tic disorders. Results: Our review found a closer relationship between TTM and tic disorder from neurobiological (especially imaging) and therapeutic standpoints. Conclusion: We sought to challenge the DSM-5 classification of TTM and to compare TTM with both OCD and tic disorder. Some discrepancies between TTM and tic disorders notwithstanding, several arguments are in favor of a closer relationship between these two disorders than between TTM and OCD, especially when considering implications for therapy. This consideration is essential for patients.

Tricotilomanía: abordaje diferenciado según la franja etaria en la infancia / Trichotillomania: differentiated approach depending on the age group in children

Introducción: La tricotilomanía se caracteriza por áreas de alopecia causadas por la tracción de cabellos realizada por el mismo paciente y es más frecuente en edades pediátricas. No obstante, existen pocos trabajos sobre esta enfermedad. Este estudio tiene como objetivo delinear las características clínicas y evolutivas de la tricotilomanía en un grupo de niños Resultados: Hubo 47 casos de tricotilomanía, de los cuales 32 (68%) fueron niñas. Se observó una mayor predisposición en el género femenino luego de los 5 años (mientras en las menores de 5 años el 56% estuvo afectada, en las mayores de 5 años el porcentaje se elevó al 76%). La edad media de inicio fue de 6 años, variando entre los 7 meses y los 11 años. La presencia de factores precedentes como cambios en la dinámica familiar, problemas psicológicos y enfermedades se determinó en 29 pacientes y fue más común en los niños mayores de 5 años. La región parieto-temporal fue la más afectada y las pestañas y cejas las menos comprometidas. En el 74% de los casos se inició tratamiento con placebo y se obtuvo una buena respuesta...

Tricotilomania: [revisão] / Trichotillomania: [review]

CONTEXTO: Relatada desde a Antiguidade, a tricotilomania (TTM) somente na última década despertou maior interesse clínico, sendo incluída no DSM-IV-TR (The Diagnostic and Statistical Manual of Mental Disorders 4th Text Revision) como um transtorno do controle dos impulsos não especificado. Dados recentes estimam uma prevalência em torno de 3 por cento, indicando uma incidência mais comum do que se imaginava. Aspectos clínicos e terapêuticos ainda não estão totalmente definidos. OBJETIVO: Revisão sistemática da literatura de vários aspectos da tricotilomania pertinentes à teoria clínica e prática. MÉTODO: Os termos "trichotillomania", "epidemiology", "clinical characteristics", "etiology", "comorbidity" e "treatment" foram consultados nas bases de dados Medline/PubMed, Lilacs, PsycINFO e Cochrane Library. RESULTADOS: Pesquisas com populações não clínicas sugerem que a TTM é mais comum do que se acreditava. Aspectos fenomenológicos, taxonômicos, comorbidades e possibilidades terapêuticas são discutidos. CONCLUSÃO: Apesar de um crescente número de estudos recentes, questões clínicas e terapêuticas permanecem em aberto. Com base nesta revisão da literatura, sugerem-se direções para diagnóstico, tratamento e futuras pesquisas.

BACKGROUND: Recognized since antiquity, only within the last decade has the subject of trichotillomania provoked any larger clinical interest since it has been included in the DSM-IV-TR (The Diagnostic and Statistical Manual of Mental Disorders 4th Text Revision) as a disturbance of the impulse-control disorders not elsewhere classified. Recent data estimates its prevalence at around 3 percent. Although more common than it was imagined before, clinical and therapeutic aspects are still not well defined. OBJECTIVE: Systematic revision in the literature of several aspects of trichotillomania and its clinical and practical theory. METHOD: The term "trichotillomania", "its epidemiology", "clinical characteristics", "etiology", "comorbidity" and "treatment" were searched in the data bases of Medline/ PubMed, Lilacs, PsycINFO and Cochrane Library. RESULTS: Research with no clinical populations suggests that TTM is more common than it was previously suspected. Phenomenological and taxonomical aspects, comorbidity as well as therapeutic possibilities are discussed. CONCLUSION: Despite a growing number of recent studies, clinical and therapeutic aspects remain undefined. Based on this literature's review, directions are suggested concerning diagnosis, treatment and future research.

Pattern of skin disorders in Muzaffarabad: a comparison of pre- and post-earthquake scenario

Psyche and skin are closely related. The anatomical and physiological integrity is maintained when they are congruent in their functioning. Natural calamities and disasters affect this harmony adversely by causing psychological as well as physical trauma, which leads to a number of immediate as well as long term skin ailments. The study was aimed to observe any change in pattern of skin diseases in Muzaffarabad after devastating earthquake of October 8th, 2005. Patients and methods The study was carried out in CMH, Muzaffarabad from March, 2006 to August 2006. Patient's record of same six months of last year was retrieved and was compared with present record. Patients of all ages, with any cutaneous disease, attending the outpatient departments or admitted to the skin ward of Combined Military Hospital Muzaffarabad, from 1St March 2006 to 31St August 2006, were included in the study. A detailed dermatological evaluation was carried out in all patients. Relevant investigations like o scraping for fungus and biopsy were done when required. Indoor as well as outpatients' record for the same period of last year [2005] was retrieved. The information were duly documented and compiled. Prevalence of various common skin disorders was compared in pre and post earthquake scenario and statistical evaluation was done by calculating p-value after applying z-test. In post-earthquake period, overall proportion of skin patients increased when compared with similar per-earthquake period. Infections remained at the top in both scenarios but their proportion increased significantly after earthquake period. Psychocutaneous disorders like, trichotillothania and dermatitis artifacta were also frequently seen in post- earthquake period. Hair, nail, pigmentary disorders, sexually transmitted infections were statistically less frequent in post earthquake period. Eczemas, psoriasis and vitiligo were also less frequently reported. A significant increase in overall proportion of skin patients and prevalence of bacterial infections, viral infections, scabies and certain psychocutaneous disorders was probably related to compromised hygiene and sanitation and psychological trauma as consequence of devastating earthquake of October 8th, 2005
