Anaesthesia, Rajmata Vijaya Raje Scindia Medical College, Bhilwara, IND.

Trichobezoar, a rare disorder commonly seen in psychiatric patients having a habit of plucking and eating their own hair, is a ball of hair admixed with gastro-intestinal secretions that leads to the blocking of the passage of food particles. Presentation of the disease is variable, ranging from asymptomatic to severe complications including obstruction and perforation. We report a case of a 27-year-old female patient who presented with an acute abdomen and on laparotomy, gastric perforation secondary to large gastric trichobezoar was found. Read More

The role of compulsivity in body-focused repetitive behaviors.

J Psychiatr Res 2022 May 5;151:365-367. Epub 2022 May 5.

Department of Psychiatry, Faculty of Medicine, University of Southampton, UK; Southern Health NHS Foundation Trust, Southampton, UK.

Trichotillomania (TTM) and skin picking disorder (SPD) have been characterized as body-focused repetitive behaviors (BFRBs) and have been grouped in the DSM-5 as part of the obsessive-compulsive and related disorders. Despite the clinical similarities between BFRBs and the compulsions of OCD, there has been little research regarding the degree to which compulsivity underpins these behaviors. 88 adults (69 female; mean age 30.

Department of Psychiatry & Behavioral Neuroscience, University of Chicago, Pritzker School of Medicine, Chicago, IL, USA. Electronic address:

Background: Individuals with trichotillomania (TTM), a disorder characterized by repetitive pulling out of one's own hair, often have co-occurring ADHD, but little is known about this comorbidity. Additionally, there have been intimations in the literature that treatment of ADHD with stimulants may worsen TTM symptoms. This study aims to examine clinical aspects of individuals with TTM and co-occurring ADHD. Read More

Radiol Case Rep 2022 Jun 22;17(6):2243-2246. Epub 2022 Apr 22.

Haematology Unit, Department of Internal Medicine, Sarawak General Hospital, Ministry of Health, Sarawak, Malaysia.

We report a case of Rapunzel's syndrome associated with trichotillomania in a 16-year-old girl who presented to our Haematology unit with complaints of fatigue, abdominal distention, and early satiety. Initial evaluation demonstrated anaemia, thrombocytosis, and a left hypochondrial mass suggestive of splenomegaly. Read More

We present a systematic literature review followed by meta-analyses assessing whether peripheral oxytocin (OXT) levels among psychiatric patients differ from healthy controls, considering the moderating role of methodological aspects and samples' characteristics. The following electronic databases were searched: PubMed, Web of Science, PsycINFO, SciELO, LILACS, and Scopus. Read More

Sociodemographic variables, clinical characteristics, and treatments in children with trichotillomania in terms of age and gender: a multicenter study.

Nord J Psychiatry 2022 Mar 30:1-10. Epub 2022 Mar 30.

Department of Child and Adolescent Psychiatry, Ataturk University, Erzurum, Turkey.

Objective: Although trichotillomania (TTM) is a common, typically pediatric-onset disorder, data on the phenomenology of TTM in children, accompanying comorbid psychiatric disorders, and treatment options are extremely limited. In our study, it was aimed to investigate these variables and related factors in patients undergoing psychiatric evaluation and follow-up.

Method: The study included 79 children and adolescents between the ages of 4 and 17 who were diagnosed with TTM and followed up in four different Child and Adolescent Psychiatry outpatient clinics between 2015 and 2020. Read More

Pain perception and physiological correlates in body-focused repetitive behavior disorders.

CNS Spectr 2022 Mar 22:1-8. Epub 2022 Mar 22.

Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, California, USA.

Background: Behaviors typical of body-focused repetitive behavior disorders such as trichotillomania (TTM) and skin-picking disorder (SPD) are often associated with pleasure or relief, and with little or no physical pain, suggesting aberrant pain perception. Conclusive evidence about pain perception and correlates in these conditions is, however, lacking.

Methods: A multisite international study examined pain perception and its physiological correlates in adults with TTM (n = 31), SPD (n = 24), and healthy controls (HCs; n = 26). Read More

A prospective clinical cohort-based study of the prevalence of OCD, obsessive compulsive and related disorders, and tics in families of patients with OCD.

BMC Psychiatry 2022 03 17;22(1):190. Epub 2022 Mar 17.

Chaim Sheba Medical Center, Post Trauma Center, Ramat-Gan, Israel.

Background: The lifetime prevalence of obsessive - compulsive disorder (OCD) is currently estimated at 2 - 3% and the prevalence in first-degree family members is estimated to range between 10 and 11%. Separating OCD from other anxiety disorders and including it into the new "obsessive - compulsive and related disorders" (OCRDs) category has had a dramatic impact on the diagnosis, while also contributing to the better understanding of the genetics of these disorders. Indeed, grouping OCD with body dysmorphic disorder (BDD), and body-focused repetitive behaviors such as trichotillomania (hair pulling), onychophagia (nail biting), and excoriation (skin picking) into the same diagnostic family has resulted in a much greater lifetime prevalence (> 9%).

Neural basis of associative learning in Trichotillomania and skin-picking disorder.

Behav Brain Res 2022 05 18;425:113801. Epub 2022 Feb 18.

Psychology Program, University of Applied Sciences Europe, Berlin, Germany.

Disorders such as Trichotillomania (TTM) and skin-picking disorder (SPD) are associated with reduced flexibility and increased internally focused attention. While the basal ganglia have been hypothesized to play a key role, the mechanisms underlying learning and flexible accommodation of new information is unclear. Using a Bayesian Learning Model, we evaluated the neural basis of learning and accommodation in individuals with TTM and/or SPD. Read More

Quality of life in trichotillomania: An assessment of specific life domains.

Ann Clin Psychiatry 2022 02;34(1):27-32

Department of Psychiatry and Behavioral Neuroscience, University of Chicago Chicago, Illinois, USA.

Background: The Quality of Life Inventory (QOLI) gauges importance and satisfaction ratings in areas of life such as work, health, and family. An examination of QOLI scores among individuals with trichotillomania (TTM), a hair-pulling disorder, might provide insight on domain-specific interventions to counteract factors that may be contributing to lower quality-of-life (QOL) scores.

Methods: Three hundred thirty-three adults with TTM and 90 healthy controls (age 18 to 65) completed the QOLI and various symptom severity measures. Read More

A Hierarchical Personality Approach Toward a Fuller Understanding of Onychophagia and Compulsive Buying.

Psychol Rep 2022 Feb 11:332941211061696. Epub 2022 Feb 11.

New Kensington Campus, Penn State University , Kensington, PA, U.S.A.

Purpose: Employing a hierarchical model of personality, prior research suggests that cardinal traits such as conscientiousness and agreeability predict central traits such as materialism and need for arousal that in turn impact surface traits such as onychophagia and compulsive buying. More research is needed to explore additional central traits and their effect on onychophagia and compulsive buying. Thus, the goal of the current research is to examine how another central trait-negative perfectionism-impacts onychophagia and compulsive buying. Read More

Trichotillomania: What Do We Know So Far?

Skin Appendage Disord 2022 Jan 1;8(1):1-7. Epub 2021 Sep 1.

Phillip Frost Department of Dermatology and Cutaneous Surgery, University of Miami School of Medicine, Miami, Florida, USA.

Trichotillomania is defined as an obsessive-compulsive or related disorder in which patients recurrently pull out hair from any region of their body. The disease affects mainly female patients, who often deny the habit, and it usually presents with a bizarre pattern nonscarring patchy alopecia with short hair and a negative pull test. Trichoscopy can reveal the abnormalities resulting from the stretching and fracture of hair shafts, and biopsy can be necessary if the patient or parents have difficulties in accepting the self-inflicted nature of a trichotillomania diagnosis.
