Functional neural mechanisms of sensory phenomena in obsessive-compulsive disorder.

J Psychiatr Res 2018 Nov 21;109:68-75. Epub 2018 Nov 21.

Department of Psychiatry, New York University School of Medicine, New York, NY, USA; Nathan Kline Institute for Psychiatric Research, Orangeburg, NY, USA. Electronic address:

Sensory phenomena (SP) are aversive or uncomfortable sensations that accompany and/or drive repetitive behaviors in obsessive-compulsive disorder (OCD). Although SP are associated with significant distress and may respond less well to standard treatments than harm-related obsessions, little is known about their underlying neurobiology. The present study used functional magnetic resonance imaging (fMRI) to measure brain functioning related to severity of SP during a "body-focused" videos task designed to elicit activation in sensorimotor brain regions.

Use of antipsychotic drugs in dermatology.

Clin Dermatol 2018 Nov - Dec;36(6):765-773. Epub 2018 Aug 16.

Department of Medicine, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada.

Antipsychotic drugs can be beneficial in dermatology because of their both central nervous system and peripheral effects. All antipsychotic drugs have a central postsynaptic dopamine D2 receptor blocking effect, which underlies their antipsychotic action. The antipsychotic drugs have varying degrees of histamine H1-receptor, cholinergic muscarinic receptor, and α1-adrenergic receptor blocking effects, which can affect cutaneous perception and the autonomic reactivity of the skin and can be potentially beneficial in the management of certain histamine or sympathetically mediated dermatologic manifestations (eg, urticaria, pruritus, hyperhidrosis).

Use of antiepileptic mood stabilizers in dermatology.

Clin Dermatol 2018 Nov - Dec;36(6):756-764. Epub 2018 Aug 16.

Department of Medicine, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada.

Several antiepileptic drugs (AEDs) are approved by the US Food and Drug Administration for the treatment of bipolar disorder (valproic acid, divalproex, lamotrigine, carbamazepine) and some cutaneous neuropathic pain syndromes (carbamazepine, gabapentin, pregabalin). The AEDs may be effective in the management of (1) chronic pruritus, including pruritus due systemic disease, including uremia, neuropathic pain, neuropathic pruritus, and complex cutaneous sensory syndromes, especially where central nervous system (CNS) sensitization plays a role; (2) management of emotional dysregulation and the resultant repetitive self-excoriation or other cutaneous self-injury in patients who repetitively stimulate or manipulate their integument to regulate emotions (prurigo nodularis, lichen simplex chronicus, skin picking disorder, trichotillomania); (3) management of dermatologic clinical manifestations associated with autonomic nervous system activation (hyperhidrosis, urticaria, flushing; these often occur in conjunction with psychiatric disorders with prominent autonomic activation and dysregulation, eg, social anxiety disorder, posttraumatic stress disorder); and (4) when certain anticonvulsants have a direct therapeutic effect (eg, in psoriasis); currently the use of AEDs for such cases is largely experimental. Gabapentin (dosage range 300-3600 mg daily) is the most widely studied AED mood stabilizer in dermatology and is especially effective in situations where CNS sensitization is a mediating factor.

Assessment and treatment of trichotillomania (hair pulling disorder) and excoriation (skin picking) disorder.

Clin Dermatol 2018 Nov - Dec;36(6):728-736. Epub 2018 Sep 19.

The OCD and Related Disorders Program, Massachusetts General Hospital, Boston, Massachusetts, USA. Electronic address:

Recommendations are provided for the assessment and treatment of trichotillomania (hair pulling disorder, or HPD) and excoriation disorder (skin picking disorder, or SPD), two body-focused repetitive behavior (BFRB) disorders, based on their severity, comorbidities, and behavioral style. Habit reversal training (HRT) and stimulus control are first-line behavioral treatments that can be used in cases of all severity levels and may be particularly helpful when pulling or picking is performed with lowered awareness/intention. Acceptance and commitment therapy (ACT) and dialectical behavior therapy (DBT) are behavioral treatments that can be employed to augment HRT/stimulus control, especially when negative emotions trigger the pulling or picking.

Department of Psychological and Brain Sciences, Texas A&M University, College Station, TX, USA; Department of Psychology, Marquette University, Milwaukee, WI, USA.

Body-focused repetitive behaviors (BFRBs), such as hair pulling, skin picking, and nail biting are common habits, but their pathological manifestations have been considered rare. Growing evidence suggests pathological forms of these behaviors can be conceptualized as a class of related disorders. However, few previous studies have examined the collective prevalence of related pathological BFRBs. Read More

The psychodynamic significance of trichotillomania: a case study.

Riv Psichiatr 2018 Jul-Aug;53(4):214-217

Cattedra di Psichiatria, Dipartimento di Medicina dei Sistemi, Università di Roma Tor Vergata.

In this paper we present a case of trichotillomania which lasted 33 years, starting with the patient's menarche at 12 years old, and lasting until her first and only pregnancy at 45 years old. We explore the psychodynamic meaning of the hair pulling, both in light of the problems related to introjective and projective processes which, in the kleinian view, gives structure to the internal world and, according to Margaret Mahler, individuation-separation theory. The hypotheses on the significance of this symptom are discovered in part in light of the material which emerged from the patient's intermittent participation in group psychotherapy for nearly five years prior to her pregnancy.

Ectoparasite defence in humans: relationships to pathogen avoidance and clinical implications.

Philos Trans R Soc Lond B Biol Sci 2018 Jul;373(1751)

Department of Anthropology and Center for Behavior, Evolution and Culture, University of California, Los Angeles, Los Angeles, CA 90095-1553, USA.

Currently, disgust is regarded as the main adaptation for defence against pathogens and parasites in humans. Disgust's motivational and behavioural features, including withdrawal, nausea, appetite suppression and the urge to vomit, defend effectively against ingesting or touching sources of pathogens. However, ectoparasites do not attack their hosts via ingestion, but rather actively attach themselves to the body surface. Read More

Trichotillomania Ranging from "Ritual to Illness" and as a Rare Clinical Manifestation of Frontotemporal Dementia: Review of Literature and Case Report.

Int J Trichology 2018 Mar-Apr;10(2):84-88

Department of Neurology, National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India.

Frontotemporal dementia (FTD) is the most common form of dementia in the younger age group and often exists with comorbid obsessions and compulsions in up to 80% of the patients. Trichotillomania or compulsive "hair-pulling" disorder is a rare manifestation of FTD and is a poorly evaluated symptom in this condition. The release of "grooming functions" due to frontal disinhibition is often attributed to the evolutionary perspective; however, recent findings also implicate the role of neurotransmitter dysfunction.
