We here report the case of a girl with trichotillomania involving her left eyelashes due to low self-esteem. Read More

    Striatal abnormalities in trichotillomania: a multi-site MRI analysis.
    Neuroimage Clin 2018 22;17:893-898. Epub 2017 Dec 22.
    Department of Psychiatry, University of Cambridge, UK.
    Trichotillomania (hair-pulling disorder) is characterized by the repetitive pulling out of one's own hair, and is classified as an Obsessive-Compulsive Related Disorder. Abnormalities of the ventral and dorsal striatum have been implicated in disease models of trichotillomania, based on translational research, but direct evidence is lacking. The aim of this study was to elucidate subcortical morphometric abnormalities, including localized curvature changes, in trichotillomania. Read More

    Corticostriatal circuit defects in Hoxb8 mutant mice.
    Mol Psychiatry 2017 Sep 26. Epub 2017 Sep 26.
    Department of Human Genetics, University of Utah School of Medicine, Salt Lake City, UT, USA.
    Hoxb8 mutant mice exhibit compulsive grooming and hair removal dysfunction similar to humans with the obsessive-compulsive disorder (OCD)-spectrum disorder, trichotillomania. As, in the mouse brain, the only detectable cells that label with Hoxb8 cell lineage appear to be microglia, we suggested that defective microglia cause the neuropsychiatric disorder. Does the Hoxb8 mutation in microglia lead to neural circuit dysfunctions? We demonstrate that Hoxb8 mutants contain corticostriatal circuit defects. Read More

Patients with diagnosed celiac disease may have an urge to swallow their hair due to iron or folat deficiency, which is called pica. Read More

    Excoriation (skin-picking) disorder: a systematic review of treatment options.
    Neuropsychiatr Dis Treat 2017 14;13:1867-1872. Epub 2017 Jul 14.
    SU/UCT MRC Unit on Risk and Resilience in Mental Disorders, Department of Psychiatry and Mental Health, University of Cape Town, South Africa.
    Although pathological skin-picking has been documented in the medical literature since the 19th century, it has only recently been included as a distinct entity in psychiatric classification systems. In the, 5th Edition and the proposed International Classification of Diseases, Eleventh Revision, excoriation (skin-picking) disorder (ED), also known as neurotic excoriation, psychogenic excoriation, or dermatillomania), is described as recurrent picking of skin, leading to skin lesions and significant distress or functional impairment. ED is listed as one of the obsessive-compulsive and related disorders, given its overlap with conditions such as trichotillomania (hair-pulling disorder). Read More

    Trichotillomania is a functionally impairing, often overlooked disorder with no Food and Drug Administration-approved medications indicated for its treatment. The ability of clinical trials to detect the beneficial effects of pharmacologic treatment in trichotillomania has been hampered by the high placebo response rate. Very little is known about baseline demographic and clinical characteristics that may be predictive of placebo response in such patients. Read More

    Dissociation and conversion symptoms in dermatology.
    Clin Dermatol 2017 May - Jun;35(3):267-272. Epub 2017 Jan 21.
    Department of Medicine, Faculty of Medicine, University of Toronto, Ontario, Canada.
    Dissociation and conversion (defined as the somatic component of dissociation) can play an important mediating role in the exacerbation of the stress-reactive dermatoses (eg, psoriasis, idiopathic urticaria, atopic dermatitis), dermatoses that are exacerbated by excessive scratching (eg, lichen simplex chronicus, prurigo nodularis) and koebnerization, and the self-induced dermatoses (dermatitis artefacta, acne excoriée, skin picking disorder, trichotillomania, onychotillomania/onychophagia). Dissociative symptoms often coexist with obsessive-compulsive symptoms in the more severe cases of the self-induced dermatoses. Dissociation can play an important role in cutaneous sensory disorder (eg, scalp dysesthesia syndrome, stomatodynia/glossodynia, vulvodynia/scrotodynia, medically unexplained anesthesia). Read More

    Posttraumatic stress disorder (PTSD) and the dermatology patient.
    Clin Dermatol 2017 May - Jun;35(3):260-266. Epub 2017 Jan 22.
    Department of Medicine, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada.
    Dermatologic symptoms can be associated with posttraumatic stress disorder (PTSD) in several situations: (1) as features of some core PTSD symptoms, such as intrusion symptoms manifesting as cutaneous sensory flashbacks, as autonomic arousal manifesting as night sweats and idiopathic urticaria, and as dissociation manifesting as numbness and dermatitis artefacta; (2) the cutaneous psychosomatic effects of emotional and physical neglect and sexual abuse (eg, infantile eczema, cutaneous self-injury, and body-focused repetitive behaviors such as trichotillomania and skin picking disorder) and eating disorders, which can have dermatologic effects; (3) the direct effect of physical or sexual abuse or catastrophic life events (eg, earthquakes) on the skin; and (4) as a result of significant alterations in hypothalamic-pituitary-adrenal and sympatho-adrenal medullary axes, which can affect neuroendocrine and immune functions, and can lead to exacerbations of stress-reactive inflammatory dermatoses such as psoriasis, chronic urticaria, and atopic dermatitis. Elevated levels of inflammatory biomarkers and impaired epidermal barrier function have been reported in situations involving sustained psychologic stress and sleep deprivation. Some PTSD patients show hypothalamic-pituitary-adrenal axis hyporesponsiveness and higher circulating T lymphocytes, which can exacerbate immune-mediated dermatologic disorders. Read More
