    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

    Preventing, treating, and predicting barbering: A fundamental role for biomarkers of oxidative stress in a mouse model of Trichotillomania.
    PLoS One 2017 20;12(4):e0175222. Epub 2017 Apr 20.
    Department of Comparative Medicine, Stanford University, Stanford, California, United States of America.
    Barbering, where a "barber" mouse plucks hair from its cagemates or itself, is both a spontaneously occurring abnormal behavior in mice and a well validated model of Trichotillomania (TTM). N-Acetylcysteine, (NAC) a cysteine derived food additive, is remarkably effective in treating TTM patients, but its mechanism of action is unknown. Reactive Oxygen Species (ROS), also known as free radicals, form as a natural byproduct of the normal metabolism of oxygen. Read More

    Department of General Psychology, University of Padova, via Venezia 8, 35131 Padova, Italy.
    Etiological models of trichotillomania (TTM) conceptualize hair pulling as a dysfunctional emotion regulation strategy; accordingly, some research has found that affective states change differentially across the hair pulling cycle. We explored emotional changes in a sample of Italian individuals reporting TTM. Eighty-nine participants reporting TTM completed a 12-item section of the Italian Hair Pulling Questionnaire online and rated the extent to which they had experienced 12 affective states before, during, and after hair pulling.

    Obsessive-compulsive skin disorders: a novel classification based on degree of insight.
    J Dermatolog Treat 2016 Oct 24:1-5. Epub 2016 Oct 24.
    b Department of Dermatology, Psoriasis and Skin Treatment Center , University of California San Francisco , San Francisco , CA , USA.
    Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5.

    Hair plucking, stress, and urinary cortisol among captive bonobos (Pan paniscus).
    Zoo Biol 2016 Sep 17;35(5):415-422. Epub 2016 Aug 17.
    Department of Anthropology, University of Oregon, Eugene, Oregon.
    Hair plucking has been observed in many captive primate species, including the great apes; however, the etiology of this behavioral pattern is poorly understood. While this behavior has not been reported in wild apes, an ethologically identical behavior in humans, known as trichotillomania, is linked to chronic psychosocial stress and is a predominantly female disorder. This study examines hair plucking (defined here as a rapid jerking away of the hair shaft and follicle by the hand or mouth, often accompanied by inspection and consumption of the hair shaft and follicle) in a captive group of bonobos (N = 13) at the Columbus Zoo and Aquarium in Columbus, Ohio.
