Abstract
OBJECTIVES Although trichotillomania (TTM) is classified in the obsessive-compulsive disorders (OCD) chapter of the DSM-5, several studies showed that it has several differences. The aim of this study was to examine the phenomenology, comorbidity, and family psychiatric characteristisc of childhood TTM and OCD. METHODS This study compared youth ages 6-17 years with a primary diagnosis of TTM (n = 63) to those with primary OCD (n = 65) on clinical and familial psychiatric characteristics. RESULTS In our study, the findings showed that family history of schizophrenia (42.3%) was higher among patients with TTM than the OCD group, while the history of OCD (55.8%) in the family was significantly higher among the OCD group (p < 0.001). The behaviour of plucking eyebrows was significantly higher among patients with TTM comorbid OCD than patients with only trichotillomania. TTM patients with comorbid OCD had one-dimensional symptom distribution than the presence of the OCD-only group, and the severity of OCD was lower. The incidence of pathological doubting was higher among the TTM group with comorbid OCD, than those with only OCD diagnosis. CONCLUSIONS These findings support significant differences between OCD and TTM. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches.KEYPOINTSWe aimed to compare the trichotillomania in itself and in the presence of OCD with the OCD group.Even if OCD accompanied trichotillomania, OCD symptom dimensions and severity were found to be lower than in the OCD-only group.Trichotillomania is a heterogeneous disorder with different dimensions besides the OCD spectrum.

Abstract
In modern societies, there is a strive to improve the quality of life related to risk of crimes which inevitably requires a better understanding of brain determinants and mediators of aggression. Neurobiology provides powerful tools to achieve this end. Pre-clinical and clinical studies show that changes in regional volumes, metabolism-function and connectivity within specific neural networks are related to aggression. Subregions of prefrontal cortex, insula, amygdala, basal ganglia and hippocampus play a major role within these circuits and have been consistently implicated in biology of aggression. Genetic variations in proteins regulating the synthesis, degradation, and transport of serotonin and dopamine as well as their signal transduction have been found to mediate behavioral variability observed in aggression. Gene-gene and gene-environment interactions represent additional important risk factors for aggressiveness. Considering the social burden of pathological forms of aggression, more basic and translational studies should be conducted to accelerate applications to clinical practice, justice courts, and policy making.

Abstract
Objective: To investigate the clinical implications of obsessive-compulsive disorder (OCD) and ADHD comorbidity in adults. Method: The OCD patients who had and had no diagnosis of adulthood ADHD were compared in terms of several demographic and clinical variables. Results: The mean number of obsessions and compulsions; hoarding, symmetry, and miscellaneous obsessions; ordering/arranging and hoarding compulsions; total, attentional, and motor subscale scores of Barratt Impulsivity Scale (BIS)-11 were more frequent among the patients with OCD-ADHD. The mean age of onset was more likely to be earlier in ADHD-OCD group than in OCD group. Impulsivity, symmetry obsessions, and hoarding compulsions strongly predicted the coexistence between ADHD and OCD. Conclusion: OCD-ADHD comorbidity in adults seemed to be associated with an earlier onset of OCD, with the predominance of impulsivity, and with a different obsessive-compulsive symptom (OC) profile from OCD patients without a diagnosis of ADHD.

Abstract
BACKGROUND Trichotillomania (TTM), excoriation (or skin-picking) disorder and some severe forms of onychophagia are classified under obsessive-compulsive and related disorders. There are different interacting neurotransmitter systems involved in the pathophysiology of impulse-control disorders, implicating noradrenaline, serotonin, dopamine, opioid peptides and glutamate, hence investigators focused on drugs able to act on these transmitters. Our aim was to critically review the efficacy of the drugs employed in impulse-control disorders. METHODS We searched for controlled drug trials to treat TTM, excoriation, and/or nail-biting six databases (PubMed, Cochrane, Scopus, CINAHL, PsycINFO/PsycARTICLES, and Web of Science), using the search strategy: (trichotillomania OR "excoriation disorder" OR "face picking" OR "skin picking" OR "hair pulling" OR onychophagia OR "nail-biting") AND drug treatment on 12 March 2018 for all databases. We followed in our method of identifying relevant literature the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS SSRIs and clomipramine are considered first-line in TTM. In addition, family members of TTM patients are often affected by obsessive-compulsive spectrum disorders. Other drugs used in the treatment of TTM are lamotrigine, olanzapine, N-Acetylcysteine, inositol, and naltrexone. CONCLUSION The treatment of TTM, excoriation disorder and nail-biting is still rather disappointing. Conjectures made from preclinical studies and the relative pathophysiological hypotheses found poor confirmations at a clinical level. There is a need for further studies and the integration of pharmacological and psychotherapeutic. Our results point to the need of integrating personalised medicine principles in the treatment of these patients.

Abstract
Trichotillomania (hair pulling disorder, HPD) is characterized by significant psychological distress, childhood-onset, and, in adults, certain cognitive deficits such as inhibitory control. A total absence of such literature exists within pediatric HPD samples, including research investigating neurocognitive aspects of disparate pulling-styles. The present study aims to address these gaps in the literature. Youth with HPD and healthy controls (N = 45) were compared on an automated neurocognitive task--stop-signal task (SST)--assessing inhibitory control. Youth with HPD (n = 17), controlling for age and attention issues, were found to perform better on the stop-signal reaction time compared to controls (n = 28). No significant relationships between performance on the SST and HPD severity, distress/impairment, or pulling-styles were noted. Findings from the current study suggest that children with HPD may not exhibit deficits in motor inhibition as compared to controls when the effects of age and attentional problems are controlled.

Abstract
Objective Although the relationship between obsessive compulsive disorder (OCD) and impulsivity has long been debated, impulsivity has not been systematically examined in clinical samples of OCD. Meanwhile, recent findings suggest that impulsivity is multi-dimensional construct that can be examined through several constructs. Therefore, this study is aimed to evaluate multiple facets of impulsivity in OCD. Method The recruitment includes 80 OCD and 76 healthy control participants. Participants completed a test battery comprising three behavioral tasks of stop signal task (SST), delay discounting task (DDT) and balloon analog risk test (BART), and one self-report measure of the Barratt Impulsiveness scale (BIS-11). Results OCD subjects showed significantly lower stop signal reaction time of SST reflecting higher action impulsivity and higher delay discounting parameter of DDT suggesting increased choice impulsivity but significantly lower adjusted mean pump of BART implying lower risk taking propensity of BART than healthy control. Conclusion Increased Action and choice impulsivity, and decreased risk taking propensities were found in OCD. These findings seem to be consistent with clinical characteristics of OCD such as greater preference for or avoid risky situations (avoidance), inability to wait tension relief may provoke safety behaviors (compulsion) and inability to stop already started behaviors (repetition).

Abstract
The purpose of the article was to provide an overview of patient-reported outcomes (PROs) and related measures that have been examined in the context of obsessive-compulsive disorder (OCD). The current review focused on patient-reported outcome measures (PROMs) that evaluated three broad outcome domains: functioning, health-related quality of life (HRQoL), and OCD-related symptoms. The present review ultimately included a total of 155 unique articles and 22 PROMs. An examination of the PROs revealed that OCD patients tend to suffer from significant functional disability, and report lower HRQoL than controls. OCD patients report greater symptom severity than patients with other mental disorders and evidence indicates that PROMs are sensitive to change and may be even better than clinician-rated measures at predicting treatment outcomes. Nonetheless, it should be noted that the measures reviewed lacked patient input in their development. Future research on PROMs must involve patient perspectives and include rigorous psychometric evaluation of these measures.

Abstract
Objective: Trichobezoar consists of a compact mass of hair occupying the gastric cavity to a various extent. When the trichobezoar extends past the duodenum it is better referred to as Rapunzel Syndrome. Although trichobezoars are well described in terms of surgical diagnostic and procedure, there are only but very scarce reports on psychiatric literature, usually associated with trichotillomania. The authors present a clinical case of trichobezoar and discuss the most relevant aspects concerning this entity. Methods: Presentation of psychiatric and surgical data concerning the case report. Previously reported cases are also mentioned. Results: Report of a 27-year-old female patient with a trichobezoar submitted to surgical removal, with a prior intervention 4 years before also due to trichobezoar, and with unknown psychiatric antecedents or follow-up. Conclusions: A trichobezoar represents a serious surgical condition. It is important to consider such diagnosis in face of suggestive symptoms, even if signs of trichotillomania are not present. The discrepancies between the prevalence of trichotillomania and trichobezoars due to trichophagia may be due to issues related to self-selection of patients and symptom severity. Such issues may also be important in the study of impulsive-compulsive spectrum models and to their relevance to impulse control disorders.

Abstract
Skin is an organ that has a primary function in tactile receptivity and reacts directly upon emotional stimuli. Dermatological practice involves a psychosomatic dimension. A relationship between psychological factors and skin diseases has long been hypothesized. Psychodermatology addresses the interaction between mind and skin. It is divided into three categories according to the relationship between skin diseases and mental disorders. This article reviews different dermatological conditions under each of the three categories namely psychosomatic disorders, dermatological conditions due to primary and secondary psychiatric disorders. Dermatological conditions resulting from psychiatric conditions like stress/depression and those caused by psychiatric disorders are discussed. This review intends to present the relationship between the 'skin' and the 'mind' specifically from the dermatology point of view. The effects on the quality of life as a result of psychodermatological conditions are highlighted. A multidisciplinary approach for treatment from both dermatologic and psychiatric viewpoints are suggested.

Abstract
In DSM-IV-TR, trichotillomania (TTM) is classified as an impulse control disorder (not classified elsewhere), skin picking lacks its own diagnostic category (but might be diagnosed as an impulse control disorder not otherwise specified), and stereotypic movement disorder is classified as a disorder usually first diagnosed in infancy, childhood, or adolescence. ICD-10 classifies TTM as a habit and impulse disorder, and includes stereotyped movement disorders in a section on other behavioral and emotional disorders with onset usually occurring in childhood and adolescence. This article provides a focused review of nosological issues relevant to DSM-V, given recent empirical findings. This review presents a number of options and preliminary recommendations to be considered for DSM-V: (1) Although TTM fits optimally into a category of body-focused repetitive behavioral disorders, in a nosology comprised of relatively few major categories it fits best within a category of motoric obsessive-compulsive spectrum disorders, (2) available evidence does not support continuing to include (current) diagnostic criteria B and C for TTM in DSM-V, (3) the text for TTM should be updated to describe subtypes and forms of hair pulling, (4) there are persuasive reasons for referring to TTM as "hair pulling disorder (trichotillomania)," (5) diagnostic criteria for skin picking disorder should be included in DSM-V or in DSM-Vs Appendix of Criteria Sets Provided for Further Study, and (6) the diagnostic criteria for stereotypic movement disorder should be clarified and simplified, bringing them in line with those for hair pulling and skin picking disorder.

Abstract
Body-focused repetitive behaviors such as skin picking have gained recent attention in the psychiatric literature. Prevalence of skin picking has not been well researched and is difficult to estimate; however, consequences of such behaviors can include severe medical complications and impaired social and occupational functioning. Given this, this study examined: (1) the prevalence and severity of skin picking in a nonclinical community sample, and (2) associations between skin picking and other measures of psychological functioning. Three hundred and fifty-four participants completed measures of psychological functioning and skin picking frequency and severity. A total of 62.7% endorsed some form of skin picking and 5.4% reported clinical levels of skin picking and associated distress/impact. Direct associations were found between skin picking and depressive, anxiety, and obsessive-compulsive symptoms, which may support the emotional regulation model of pathological skin picking. To establish proper diagnostic classification of pathological skin picking and optimize treatment planning and outcome, further investigation of functional relationships between skin picking and affective distress is needed.

Abstract
In closing, we argue for two conclusions. First, there are advantages to using theoretically neutral terms (such as hypersexual disorder) that go beyond the compulsive-impulsive-addictive distinctions. Although the notion of theory-neutral observation cannot be defended, it is important not to rely on any particular theoretical framework before all the evidence is in. Our current nosology employs a range of contradictory terms and frameworks (eg, impulse control disorder, compulsive gambling and buying, trichotillomania, and kleptomania). In keeping with the approach taken in other DSM categories, it may be useful to find a more theory-neutral term that can cut across these conditions. Second, any conclusions drawn here about the nosology of hypersexual disorder must be tempered by the relative lack of rigorous psychobiological and systematic treatment data. A better understanding of the psychobiology of hypersexual disorder might provide greater confidence in one or the other theoretical model. The A-B-C model proposed here is tentative at best, given the relative absence of supporting data. Further, a richer assessment and treatment literature would allow clearer conclusions about the clinical utility of different nosological approaches. We emphasize the need for much additional work to characterize the phenomenology and psychobiology of hypersexual disorder and other conditions characterized by affective dysregulation, behavioral addiction, and cognitive dyscontrol, in the hope that such research would ultimately lead to improved assessment and management.

Abstract
These practical guidelines for the biological treatment of personality disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the biological treatment of three specific personality disorders, namely borderline, schizotypal and anxious/avoidant personality disorder in addition to some general recommendations for the whole field. The guidelines cover disease definition, classification, epidemiology, course and current knowledge on biological underpinnings, and provide a detailed overview on the state of the art of clinical management. They deal primarily with biological treatment (including antidepressants, neuroleptics, mood stabilizers and some further pharmacological agents) and discuss the relative significance of medication within the spectrum of treatment strategies that have been tested for patients with personality disorders, up to now. The recommendations should help the clinician to evaluate the efficacy spectrum of psychotropic drugs and therefore to select the drug best suited to the specific psychopathology of an individual patient diagnosed for a personality disorder.

Abstract
Obsessive-compulsive and impulsive behaviors co-occur in certain psychiatric conditions. Some have suggested that these disturbances constitute a spectrum of altered psychologies and behaviors that share an underlying neuropathology. We investigate here whether obsessive-compulsiveness and impulsivity reflect related psychological dimensions in a non-clinical adolescent population. Out of 720 high-school students, 672 and 682 completed a questionnaire interview with a Chinese version of the Maudsley Obsessive-Compulsive Inventory (MOCI) and the Barratt Impulsiveness Scale (BIS-11), respectively. Both MOCI and BIS-11 demonstrated good overall internal consistency, each with three major factors identified with Principal Component Analysis. In the 638 participants who completed both questionnaires, the total MOCI and BIS-11 scores did not correlate with each other. However, the MOCI factor "repetitive checking and attention to details" correlated negatively with the BIS-11 factor "inability to plan and look ahead" for all participants, and for males and females separately. The same MOCI factor also correlated negatively with the BIS-11 factors "lack of perseverance and self-control" and "novelty-seeking and acting without thinking" for all participants, and for females but not for males. The MOCI factor "doubt and intrusive thoughts" correlated positively with the BIS-11 factor "lack of perseverance and self-control" for all participants, and for males but not for females. These results suggested that the relationship between obsessive-compulsiveness and impulsivity as measured by the MOCI and the BIS-11 is complicated, with gender playing an important modulatory role. We discuss the relevance of these findings to developing a conceptual scheme to characterize and study the neurobiological basis of obsessive-compulsive and impulsive behaviors.

Abstract
BACKGROUND Pathologic hairpulling (HP), skin picking (SP), and nail biting (NB) are repetitive, intentionally performed behaviors that cause noticeable hair loss or substantial physical damage, and result in clinically significant distress or functional impairment. To date, HP, SP, and NB have received little attention in the psychiatric literature despite being widespread behaviors. METHODS The present article reviews the up-to-date research findings on these three forms of pathologic behavior, highlighting their similarities and differences. RESULTS Despite HP, pathologic grooming behaviors have not yet been explicitly included in the diagnostic nomenclature. Phenomenology, triggers, consequences and functionality of HP, SP, and NB are similar, which suggest their joint diagnostic categorization. Sufferers often fail to admit the self-inflicted nature of their physical damage out of shame and embarrassment, which complicates the recognition and differential diagnosis of sufferers. Thus, practitioners need to be particularly attentive to physical signs possibly related to these behavior disorders. CONCLUSIONS Research suggests that HP, SP, and NB are underrecognized problems that occur on a continuum ranging from mild to severe. Further research is needed, especially regarding the etiology of pathologic HP, SP, and NB, to foster the development of both effective and long-lasting treatments and prevention strategies.

Abstract
Hallopeau, a French dermatologist, coined the term trichotillomania (TM) to describe alopecia (baldness) caused by self-traction of the hair, but the term now encompasses the entire syndrome of pathological hair-pulling. It is a disorder of impulse control. The authors present three (adult and child) cases of TM managed successfully using a combination of pharmacotherapy and a package of behaviour therapy. Some psychopathological aspects of the disorder are also discussed.

Abstract
Trichophagia secondary to trichotillomania can be a potentially life-threatening condition if left untreated. This report documents the unique case of a 16-year-old girl whose untreated trichotillomania led to a trichobezoar requiring surgical intervention and follow-up psychiatric treatment. Challenges in the identification and treatment of the disorder and its complications are discussed as well as the importance of early and accurate diagnosis.

Abstract
BACKGROUND Similarities between obsessive-compulsive disorder (OCD) and trichotillomania (TTM) have been widely recognized. Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions. METHODS Two hundred and seventy eight OCD patients (n = 278: 148 male; 130 female) and 54 TTM patients (n = 54; 5 male; 49 female) of all ages were interviewed. Female patients were compared on select demographic and clinical variables, including comorbid axis I and II disorders, and temperament/character profiles. RESULTS OCD patients reported significantly more lifetime disability, but fewer TTM patients reported response to treatment. OCD patients reported higher comorbidity, more harm avoidance and less novelty seeking, more maladaptive beliefs, and more sexual abuse. OCD and TTM symptoms were equally likely to worsen during menstruation, but OCD onset or worsening was more likely associated with pregnancy/puerperium. CONCLUSIONS These findings support previous work demonstrating significant differences between OCD and TTM. The classification of TTM as an impulse control disorder is also problematic, and TTM may have more in common with conditions characterized by stereotypical self-injurious symptoms, such as skin-picking. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches.

Abstract
Trichotillomania (TTM) is an enigmatic disease characterized by an overwhelming compulsion to pull out one's hair, most notably scalp hair, but also eyebrows, eyelashes, and hair from the extremity, axillary, and pubic areas. Current estimates are that clinically significant hair pulling is manifested by 3.4% of all women during their lifetimes. The overall purpose of our study was to examine the efficacy of a wide variety of treatments as perceived by the women (N=44) who received them. The data were subjected to content analysis and are presented in a quantified manner. Common forms of treatments, including pharmacotherapy, psychotherapy, and behavior modification, were judged by the respondents to be relatively ineffective. Two forms of treatment were found to be effective by a high percentage of the women who employed them: Internet TTM groups and TTM groups associated with a national center. It is important for health care providers to be aware of these treatments, which have not been previously discussed in the literature.

Abstract
Trichotillomania (TTM) is an impulse disorder, in which patients chronically pull hair from the scalp and/or other sites. Very early onset of hair pulling in children under the age of 6 may be more benign and self-limiting than the more common syndrome of late childhood onset hair pulling. While far more women and adolescent girls appear for treatment, survey studies suggest chronic hair pulling also occurs in males. Diagnosis may be complicated by patient and family denial or ignorance of the hair pulling; accurate scalp examination and biopsy can be critical. Classic scalp biopsies for TTM feature trichomalacia, pigment clumps, peribulbar hemorrhage and hair canal pigment casts, and lack lymphocytic infiltrates seen in alopecia areata. Treatment is difficult: the tricyclic antidepressant clomipramine is the most promising agent, although many patients find it difficult to tolerate at adequate dosages, and treatment response may not be maintained over the long term. More benign medications have not demonstrated efficacy in controlled studies. Augmentation with topical preparations or psychotropic medications may be helpful for patients experiencing limited efficacy or relapse. Specialized psychotherapy, known as habit reversal training, is highly recommended; however, the treatment is intensive and highly specialized. Skilled therapists are difficult to locate.

Abstract
Psychogenic excoriation (also called neurotic excoriation, acne excoriée, pathological or compulsive skin picking, and dermatotillomania) is characterised by excessive scratching or picking of normal skin or skin with minor surface irregularities. It is estimated to occur in 2% of dermatology clinic patients and is associated with functional impairment, medical complications (e.g. infection) or substantial distress. Psychogenic excoriation is not yet recognised in the DSM. We propose preliminary operational criteria for its diagnosis that take into account the heterogeneity of behaviour associated with psychogenic excoriation and allow for subtyping along a compulsivity-impulsivity spectrum. Psychiatric comorbidity in patients with psychogenic excoriation, particularly mood and anxiety disorders, is common. Patients with psychogenic excoriation frequently have comorbid disorders in the compulsivity-impulsivity spectrum, including obsessive-compulsive disorder, body dysmorphic disorder, substance use disorders, eating disorders, trichotillomania, kleptomania, compulsive buying, obsessive-compulsive personality disorder, and borderline personality disorder. There are few studies of the pharmacological treatment of patients with psychogenic excoriation. Case studies, open trials and small double-blind studies have demonstrated the efficacy of selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors in psychogenic excoriation. Other pharmacological treatments that have been successful in case reports include doxepin, clomipramine, naltrexone, pimozide and olanzapine. There are no controlled trials of behavioural or psychotherapeutic treatment for psychogenic excoriation. Treatments found to be effective in case reports include a behavioural technique called 'habit reversal'; a multicomponent programme consisting of self-monitoring, recording of episodes of scratching, and procedures that produce alternative responses to scratching; and an 'eclectic' psychotherapy programme with insight-oriented and behavioural components.

Abstract
This study evaluated behavioral and self-report indices of impulsiveness in pathological gambling substance abusers (n=27), non-pathological gambling substance abusers (n=63), and non-pathological gambling/non-substance abusing controls (n=21). The Bechara card task measured preferences for decks of cards that ranged in magnitude and probability of delayed and immediate rewards and punishers. The Stanford Time Perception Inventory (STPI) assessed orientation to the future, the Zuckerman Sensation Seeking Scale evaluated sensation seeking, and the Eysenck and Barratt scales measured impulsivity. A Principal Components analysis revealed that these personality measures comprised three distinct measures of impulsivity: impulse control, novelty seeking and time orientation. Linear contrast analyses revealed that substance abuse and pathological gambling resulted in additive effects on the impulse control and time orientation factors, but not on the novelty-seeking scale. Performance on the card task did not correlate with any of the three factors derived from the personality scale scores, but the presence of both substance abuse and pathological gambling had an additive effect on preferences for decks containing greater immediate gains but resulting in large punishers and overall net losses. These results provide further evidence of an association among substance abuse, pathological gambling, and impulsivity.

Abstract
Multiple approaches to characterization of TTM have been developed, including categoric definitions and dimensional considerations. When TTM is viewed in the context of other disorders with common comorbidities and overlapping similar phenomenologies, such as OCD, body dysmorphic disorder, skin picking, TS, and olfactory reference syndrome, clinical approaches to assessment and differential diagnosis are more complex. This article presents a general overview of TTM included as a background for a heuristic clinical framework for assessing obsessive-compulsive spectrum disorders. A comprehensive behavioral model of TTM as a template is presented in the context of a broader, phenomenologic approach to assessment of several other disorders. These additional conditions were chosen on clinical grounds because they seem to share some phenomenologic characteristics with TTM. It is hoped that combining a phenomenologic approach to the differentiation of repetitive behaviors (as has been valuable in advancing the understanding of repetitive behaviors in TS and OCD), coupled with a paradigmatic comprehensive behavioral assessment and treatment model of TTM, may foster the validation of such approaches for other putative obsessive-compulsive spectrum disorders. Also, the relative intensity and frequency ascribed to the various behavioral and phenomenologic components of the conditions depicted represent clinical impressions, with varying degrees of empiric support, and require objective validation. This approach is meant to serve as a point of departure for clinical assessment of these complex, interesting, and sometimes incompletely diagnosed and inadequately treated conditions. It is hoped that empiric validation or refutation of this conceptualization will stimulate additional research and provide clinicians with a general framework for assessing patients suffering from these difficult conditions.

Abstract
This review explores several aspects of trichotillomania relevant to clinical theory and practice. It is concluded that research outlining the phenomenology and patterns of comorbidity of trichotillomania have been advanced significantly in recent years. However, no current diagnostic category appropriately classifies trichotillomania. Research with nonclinical populations suggests that trichotillomania is more common than previously believed and that additional epidemiological research is warranted. Continued elaboration of existing etiological models incorporating varying theoretical perspectives is also encouraged. Assessment of trichotillomania could also be improved by the continued development of reliable and valid standardized measures. This article reviews both pharmacological and psychological treatments for trichotillomania, with an emphasis on habit-reversal training. Though some interventions appear effective in the short-term, reported relapse rates are high and future research on treatment for trichotillomania should focus on improving long-term outcomes. It is clear that despite a recent flux of research centering on trichotillomania, significant challenges for understanding and treating this psychological disorder still exist for researchers and clinicians. Based on this review of the literature, and on our clinical experience with trichotillomania, we propose directions for future research with this underserved psychiatric group.

Abstract
PURPOSE Trichotillomania is characterized by an irresistible urge to pull one's hair, and may involve the eyelashes or eyebrows. The authors present four cases of trichotillomania, and review the management of this unusual disorder. METHODS The cases of four patients with trichotillomania were reviewed retrospectively. RESULTS All four patients had characteristic areas of broken lashes along the lid in the absence of other signs of disease. Three of the four knew they were plucking the hair, yet could not control it. In the fourth, it was only after a lengthy observation period that she was discovered plucking. CONCLUSIONS Trichotillomania has been infrequently reported in the ophthalmic literature. Management can be difficult. Many of these patients are aware of their behavior, but are unable to curtail it. Others may conceal or deny their habit. Psychiatric counseling may be of some benefit if patients are willing to undergo it.
