From Tugs to Treatments: A Systematic Review on Pharmacological Interventions for Trichotillomania.

Trichotillomania (TTM) is a psychiatric disorder with dermatologic consequences, characterized by recurrent hair-pulling. It affects 1-3% of the population, and often coexists with other psychiatric disorders, leading to emotional distress. Effective management of TTM can be challenging due to underdiagnosis, symptom heterogeneity, and stigma. Pharmacological interventions, including SSRIs and NAC are commonly utilized. The objective of this review is to assess the existing literature on pharmacotherapy for trichotillomania and identify potential avenues for future research and treatment advancements. A systematic review of the literature was performed using PubMed and Scopus databases within the last 10 years. Included studies assessed pharmacotherapy for trichotillomania and provided insights into current evidence and potential directions for future research and treatment advancements. In total, 23 articles were identified that met inclusion criteria. The most successful interventions were NAC, aripiprazole, and monoamine oxidase inhibitors. NAC was identified as the most impressive adjunctive therapy in treatment through its mechanism of decreased glutamate-induced excitatory neuronal damage, with adjunctive antioxidant properties. Most of the other therapeutics that were identified require further research and controlled trials to validate their findings. Even if successful therapeutic outcomes are achieved, it is important to consider the patient's comorbidities and to combine pharmacologic interventions with behavioral therapy interventions to comprehensively manage TTM.

Unmet Needs in Psychodermatology: A Narrative Review.

Psychodermatology, the multidisciplinary field that explores the intricate interplay between the mind and the skin, has gained increasing recognition over the past decade. However, several knowledge gaps and unmet needs persist in the field. The objective of this narrative review was to investigate the unmet needs in the field of psychodermatology as they pertain to medical training, treatment, research, and care access. PubMed was searched from inception through December 2023 to identify articles related to psychodermatology. Findings revealed several unmet needs within the field of psychodermatology. First, there is a need for further investigation into the pathophysiology that links psychological stress to cutaneous disease including the development of novel therapies targeting key neuropeptides. Second, the existing literature focuses primarily on the pharmacologic treatment of body dysmorphic disorder and body-focused repetitive behaviors, as well as delusional parasitosis, for which the first-line agents are selective serotonin reuptake inhibitors and atypical antipsychotics, respectively. However, additional research into the efficacy and safety of the remaining psychotropic medications and the treatment of other common psychocutaneous diseases is required. Finally, there exists a significant gap in knowledge amongst clinicians tasked with treating psychocutaneous diseases. Dermatologists report low rates of training in psychodermatology and discomfort with prescribing psychotropic medications. In conclusion, increasing resources for dermatologist education on psychotropic agent use, development of new drugs targeting stress-induced skin conditions, and research on the psychocutaneous applications of current medications may greatly improve the quality and access of psychodermatology care.

INDIVIDUAL ARTICLE: Prurigo Nodularis: Current Clinicopathologic Overview and Psychodermatological Perspectives.

Prurigo nodularis (PN) is a quintessential neurocutaneous condition characterized by neural sensitization and intractable itch leading to intense scratching. This causes the formation of nodules with epidermal thickening and further release of pro-inflammatory mediators that recruit immune cells and increase dermal nerve proliferation and hypertrophy perpetuating the itch-scratch cycle. Those with PN have a significant quality-of-life (QoL) burden due to itch, anxiety, and sleep disturbance. In addition, PN exhibits psychiatric comorbidities that affect mental wellbeing such as depression, mood disorders, and substance abuse. This paper serves as an overview of the clinicopathologic aspects of PN, the burden of PN on QoL, and the psychodermatological aspects of the disease state.  J Drugs Dermatol. 2023;22:12(Suppl 2):s6-11.

Classification of psychodermatological disorders: Proposal of a new international classification.

INTRODUCTION: Several classifications of psychodermatology disorders have been proposed, with most of them based on two to four main disorder category groups. However, there is, to date, no classification that has resulted from a consensus established by psychodermatology experts. The DSM-5-TR (Diagnostic and statistical manual of mental disorders (5th ed.), Text Revision) and the ICD-11 (International classification of diseases (11th revision)) also do not provide a systematized approach of psychodermatology disorders. Taking into consideration that classifications are a key pillar for a comprehensive approach to the pathologies of each branch of medicine, the proposal of a classification in psychodermatology appeared as a central need for the recognition of psychodermatological disorders, in an attempt to improve their recognition and, in that sense, to find a common language for the development of this subspecialty that crosses dermatology and psychiatry. METHODS: Previously published classifications in psychodermatology were critically reviewed and discussed by expert opinion from an international multidisciplinary panel of 16 experts in psychodermatology and a new classification system is proposed, considering classical concepts in general dermatology and psychopathology. RESULTS: Two main categories of disorders are presented (a main group related to primary mental health disorders and another main group related to primary skin disorders), which are subsequently subdivided into subgroups considering pathophysiological and phenomenological similarities, including key aspects of dermatological examination, namely the presence of visible skin lesions (primary and secondary skin lesions) and psychopathological correlates. CONCLUSION: This new classification aims to unify previous classifications, systematize the disorders that belong to psychodermatology and highlight their tenuous boundaries, to improve their management. It has been built and approved by the Psychodermatology Task Force of the European Academy of Dermatology and Venereology (EADV), the European Society for Dermatology and Psychiatry (ESDaP) and the Association for Psychoneurocutaneous Medicine of North America (APMNA).

Psychological interventions in the treatment of delusional parasitosis: a brief review.

This review synthesized evidence on the most up-to-date treatment outcomes in patients with delusional parasitosis and examined the impact of incorporating psychological interventions in conjunction with psychiatric treatment. The reporting of this review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. PubMed and Google Scholar were searched between 2013 and 2023. Nine studies were included in this review. Partial remission was observed across all cases, irrespective of the treatment approach employed. Complete remission was limited to only three studies. No correlation was observed between the incorporation of psychological intervention in conjunction with psychotropic medication and an enhanced remission outcome. The findings underscore the importance of psychotropic medication as a fundamental component in the treatment of delusional parasitosis. The results highlight that although first- and second-generation psychotropic medications are the mainstay treatment options, they nevertheless play a limited role because of the patients' steadfast delusions of infestations.

Recent advances in trichotillomania: a narrative review.

Trichotillomania, defined as the compulsive pulling out of one's hair, is a psychocutaneous condition associated with functional impairment and decreased quality of life. The pathophysiology of trichotillomania is poorly understood and likely multifactorial, involving alterations in both neural activity and cognitive function. Behavioral treatment options for trichotillomania are limited and are often only modestly effective. Moreover, there are no medications currently approved by the U.S. Food and Drug Administration for its treatment. The gaps in knowledge regarding the neurological underpinnings and behavioral markers of trichotillomania and effective treatment options for it highlight the importance of ongoing research in this field. For this narrative review, PubMed was searched to identify articles related to trichotillomania published until July 2023. Recent advances in research on trichotillomania pathophysiology, diagnosis, clinical associations, and treatment are presented, with particular focus on how this condition uniquely spans the disciplines of both psychiatry and dermatology.

Habit-reversal training: a psychotherapeutic approach in treating body-focused repetitive behaviour disorders.

Body-focused repetitive behaviours (BFRBs) are recurrent, compulsive, destructive behaviours directed towards the body. Although studies have demonstrated a 12-14% prevalence rate, researchers found that dermatologists and psychiatrists show a lack of knowledge regarding psychodermatology resources and information about BFRB disorders (BFRBDs) such as trichotillomania (TTM). There is limited research about treatments including ones investigating the clinical applications of various self-help training such as decoupling (DC) and DC in sensu (DC-is) as well as about habit-reversal training (HRT). HRT is a five-component behavioural intervention that aims to develop a competing response to a specific unwanted behaviour. Studies have found substantial support for HRT's efficacy in treating a variety of maladaptive repetitive behaviours including onychotillomania, TTM, skin-picking disorder and chronic cheek biting. Additionally, many psychotherapies can augmented HRT. Psychotherapies include acceptance and commitment therapy, dialectical behaviour therapy, psychodynamic psychotherapy, mindfulness mediation and the cognitive psychophysiological model. A recently investigated variant of HRT, DC-is, resulted in consistently satisfactory objective and subjective improvement for treating BFRBDs, and HRT showed good subjective but poor objective improvement compared with standard DC. HRT and HRT variants are effective therapeutic treatments for BFRBDs; however, further randomized double-blinded and placebo-controlled trials are required to examine HRT's therapeutic profile.

Psychodermatology knowledge, awareness and patterns of practice among Moroccan dermatologists: a national survey study.

We aimed to assess the knowledge, attitudes and patterns of practice of Moroccan dermatologists and their awareness of psychodermatology (PD). A survey questionnaire was distributed to dermatologists and dermatology trainees from May to July 2022. A total of 112 completed surveys were received. Of these, 63.4% were dermatologists and 36.6% were dermatology residents. Of the participants, 72.3% summarized PD as the psychological impact of dermatological conditions and 50.9% reported frequent involvement with PD. Patients with a psychocutaneous condition represented a significant proportion of dermatological consultations (41.1% of dermatologists stated that 10-25% of their consultations were for psychocutaneous conditions). Only 17% felt 'very comfortable' in the management of PD conditions and 56.3% were not confident prescribing psychotropics. A total of 88.4% had never participated in PD training. Moroccan dermatologists lack a full understanding and proper training in PD. We recommend the incorporation of PD curriculum in training programmes and advocate dermatology and psychiatry liaison.

Psychiatric and psychologic aspects of chronic skin diseases.

Chronic skin diseases can substantially affect a patient's physical, psychologic, and social well-being. Physicians may play a critical role in identifying and managing the psychologic sequelae of the most common chronic skin conditions. Acne, atopic dermatitis, psoriasis, vitiligo, alopecia areata, and hidradenitis suppurativa are chronic dermatologic diseases that put patients at high risk for symptoms of depression, anxiety, and decreased quality of life. Both general and disease-specific scales exist to assess the quality of life in patients with chronic skin disease, the most common being the Dermatology Life Quality Index. The general management approach to the patient with chronic skin disease should incorporate acknowledgment and validation of the patient's struggles; patient education on the potential effect of disease and prognosis; medical management of the dermatologic lesions; coaching on stress management; and psychotherapy. Psychotherapies include talk therapy (eg, cognitive behavioral therapy), arousal-reducing therapies (eg, meditation, relaxation), and behavioral therapies (eg, habit reversal therapy). Improved understanding, identification, and management of the psychiatric and psychologic aspects of the most common chronic skin conditions by dermatologists and other health care providers may positively affect patient outcomes.

The psychological consequences of androgenetic alopecia: A systematic review.

INTRODUCTION: Androgenetic alopecia is the most common cause of hair loss in both males and females. In a society that places significant value on hair and associates it with attractiveness, a lack there of can have damaging psychological consequences. The psychosocial impact of hair loss is often overlooked due to the medically benign nature of offending conditions. Addressing the psychological aspects of androgenetic alopecia can improve holistic patient care and patient outcomes. METHODS: A search was conducted in PubMed using the following search strategy: androgenetic alopecia AND anxiety OR depression OR psychological OR psychosocial OR self-esteem. Studies were excluded if they focused on any other type of alopecia or were published in a language other than English. RESULTS: A total of 13 studies were retained after the initial search process. The included studies date from 1992 to 2021. They all conclude that androgenetic alopecia serves as a significant psychosocial stressor in the lives of those affected. It impairs quality of life according to multiple measures. CONCLUSION: The data examined from these studies shed light on the increased need to attend to the psychosocial comorbidity associated with androgenetic alopecia. These hair-loss patients often present to dermatology clinics to seek treatment but would also benefit from psychological support.

Psychopathological symptoms in dermatology: A basic approach toward psychocutaneous disorders.

Dermatological conditions impact not only an individual's physical body but also their psychological health. Similar to how cutaneous conditions can affect one's psychological health, worsening psychological conditions can exacerbate or even induce dermatological conditions. There are four common psychiatric pathologies typically found in dermatology practices: depressive symptoms, anxiety symptoms, obsessive-compulsive disorder behaviors, and psychosis. Common cutaneous disorders associated with these psychopathological symptoms include, but are not limited to, psoriasis, acne vulgaris, atopic dermatitis, urticaria, trichotillomania, excoriation disorder, and delusions of parasitosis. The goal of this review is to examine the relationship between these four psychopathological symptoms with common psychodermatological conditions and to help providers better diagnose and implement appropriate psychological support to treat their patients.

Somatization in dermatology.

Medically unexplained dermatologic symptoms, such as pruritus, numbness and burning are known as somatization. These cutaneous symptoms can be very difficult to treat because of an absence of an objective explanation and they may not fit neatly into any known dermatological or psychiatric condition. These disorders are more commonly encountered in primary care and in dermatology, rather than in psychiatry. Certain skin disorders, for example, pruritus, could be a manifestation of somatization and others may predispose to somatic symptoms, for example, atopic dermatitis and psoriasis. Although there has been increasing research in the interconnection between psychiatry and dermatology, psychodermatology is a relatively new crossover discipline in clinical practice and recognition of psychodermatological conditions, such as cutaneous somatic disorders, can be difficult. Somatization may occur with or without the existence of a dermatological disease. When a dermatological disorder is present, somatization should be considered when the patient is worrying too much about their skin, spending too much time and energy on it and especially if the patient also complains of many non-cutaneous symptoms. Purely cutaneous somatic conditions include for example, the genital pain syndromes or Gardner-Diamond syndrome, characterized by unexplained bruising, which usually affects women. Effective management tools may include mindfulness therapies, pharmacotherapy with selective serotonin reuptake inhibitors, tricyclic antidepressants and cognitive conduct therapy. Electroconvulsive therapy can also be considered in extremely rare cases for treatment of severe somatization on a background of mood disorders. This paper discusses somatization, its relationship to immunodermatoses and its relevance to clinical practice.

Global Awareness, Knowledge, and Practice Patterns of Psychocutaneous Medicine: A Primary Care Perspective.

Objective: To report findings generated from an analysis of available literature on psychodermatology knowledge, awareness, and practice patterns among dermatologists worldwide to better elucidate their educational needs and referral practices.Data Sources: To identify literature from inception to December 23, 2020, the following search strategy was used within PubMed and Google Scholar databases: psychodermatology OR psychocutaneous disorders OR psychodermatology practice patterns OR psychodermatology awareness OR psychodermatology attitudes OR psychodermatology knowledge. Non-English studies were excluded. Studies were included if they were identified as having collected data from a survey instrument assessing psychodermatology awareness, knowledge, and practice patterns of dermatologists and dermatology trainees.Study Selection and Data Extraction: Of 1,347 records screened, a total of 12 cross-sectional studies were identified as having collected data from 2,466 dermatologists in 18 countries worldwide. Individual study and overall response frequencies were extracted for each variable of interest by an independent reviewer.Results: Although most respondents provided weekly psychodermatologic care, only 13% reported feeling very comfortable treating patients with psychocutaneous concerns. Only 19% of respondents had a clear understanding of psychodermatology, and almost two-thirds of participants had no formal training in psychodermatology. Seventy-three percent of dermatologists reported interest in continuing medical education.Conclusions: A considerable number of patients present to their physician with a psychocutaneous concern. As such, dermatologists, psychiatrists, and primary care providers may benefit from an understanding of the presentations and management of the most common psychodermatology complaints. Incorporation of psychodermatology curriculums into training programs and educational activities should be considered.

Psychological Aspects of Hair Disorders: Consideration for Dermatologists, Cosmetologists, Aesthetic, and Plastic Surgeons.

Hair loss disorders may cause considerable distress to patients. Although many do not pose a significant medical risk, the sociocultural importance of hair is substantial. Often the extent of hair loss does not correlate to the impact on psychosocial function, thus necessitating an individualized approach. Hair loss disorders are interrelated with mental health and at times exert significant psychological percussions, and therefore, providers should address both medical and psychological aspects of treatment. This review contains a discussion of the impact on quality of life of common hair loss disorders and the psychological approaches that providers may utilize to improve care. The incorporation of psychodermatology and psychotrichology in dermatology and psychiatry residency programs is of vital importance. Dermatology and psychiatry liaison clinics may prove useful in the treatment of these patients.

Psychocutaneous Medicine in Iraq: Current Status and Recommendations.

Objective: To evaluate the knowledge and attitudes of Iraqi dermatologists regarding understanding, diagnosing, and treating psychocutaneous disorders.Methods: An online survey questionnaire was randomly distributed among Iraqi dermatologists through Google Forms in August 2020. The dermatologists were asked to provide information on their understanding of psychodermatology, referral patterns, level of comfort in managing psychocutaneous disorders, awareness of community resources, and interest in learning more about psychodermatology.Results: Of 200 distributed questionnaires, 61 were returned. The most common psychocutaneous disorder seen was acne, followed by alopecia areata and vitiligo. About half of the participants reported being neutral about their comfort level in treating psychocutaneous disorders, and approximately half had no formal training in psychodermatology. Almost 60% of participants did not know of any community resources, and three-quarters were willing to seek educational activities on psychodermatology.Conclusions: The study results revealed that Iraqi dermatologists have significant gaps in knowledge, training, and treatment of psychocutaneous disorders. The survey findings reveal the importance of addressing the training needs of young physicians, including dermatologists, psychiatrists, and primary care physicians, in relation to the psychological component of skin diseases.
