Psychodermatology: An Association of Primary Psychiatric Disorders With Skin

Anxiety-depression: a pivotal mental factor for accelerating disease progression and reducing curative effect in vitiligo patients

Objective

To clarify the causal relationship between anxiety-depression and the progression and outcomes of vitiligo, providing a basis for enhancing psychological interventions in the treatment of vitiligo.

Methods

A two-sample Mendelian randomization analysis was used to validate the causal relationship between anxiety, depression, and vitiligo. The Hospital Anxiety and Depression Scale (HADS) assessed the psychiatric condition of vitiligo patients. Fisher's chi-square tests and rank sum tests analyzed the differences in clinical characteristics among vitiligo patients with different HADS scores. Regression analysis assessed the correlation between anxiety-depression and disease progression and treatment outcomes.

Results

Mendelian randomization analysis showed that depression significantly increases the risk of vitiligo (OR = 4.46, 95% CI: 1.16-17.18, p = 0.03). According to the HADS scores, clinical characteristics differed significantly among the groups (p < 0.05). Univariate regression analysis demonstrated that both HADS (B = -1.168, p < 0.001, 95% CI: -1.532 to -0.804) and VIDA (B = -2.157, p < 0.001, 95% CI: -3.464 to -0.887) were significantly negative associated factors for disease outcomes. However, HADS (B = -1.006, p < 0.001, 95% CI: -1.475 to -0.657) emerged as the only factor influencing therapeutic efficacy in multivariate regression analysis. A restricted cubic spline graph illustrates a U-shaped relationship between HADS and clinical efficacy, with the most significant impact on therapeutic efficacy occurring when HADS equals 15.

Conclusion

Anxiety-depression exhibit a bidirectional positive causal relationship with vitiligo. Moderate to severe anxiety-depression significantly influences the clinical efficacy of vitiligo treatment.

Low Self-Esteem and Life Satisfaction as a Significant Risk Factor for Eating Disorders among Adolescents

Background: Eating disorders are a problem that is becoming more and more common among younger and younger age groups. Many studies examine the risk factors for EDs, however, the treatment of these diseases is very complicated and requires dietary, psychological and medical intervention. Methods: 233 primary and secondary school students aged 12 to 19 were surveyed using the EAT-26 (Eating Attitudes Test-26) questionnaire, the self-esteem Scale SES and the Cantril scale for life satisfaction. Results: Women, when compared to men, showed lower self-esteem, satisfaction with their appearance, body weight and their lives and at the same time a higher risk of eating disorders in all three areas. Low life satisfaction is often correlated with weight loss greater than 10 kg. Low self-esteem correlated positively with significant weight loss (>10 kg) and more frequent uncontrollable binge eating and exercising (more than 60 min a day) to influence appearance. People with low self-esteem were more likely to be treated for EDs. Subjects dissatisfied with their lives binged, feeling that they could not stop. Conclusion: The younger the person, the more likely they are to develop eating disorders. This is closely correlated with low self-esteem and negative life satisfaction. Men were more likely to be satisfied with their weight, appearance, and life, and were less likely to show ED symptoms.

Stigma, social appearance anxiety and coping in men and women living with skin conditions: A mixed methods analysis

Background

The psychological impact of living with a skin condition can have a profound impact on quality of life and could cause appearance-related social anxiety. Existing research suggests ambiguous findings in relation to whether the impact of living with a skin condition differs between males and females.

Objectives

The present study aimed to explore the association between stigma, coping styles and social appearance anxiety in men and women living with a skin condition in the United Kingdom.

Methods

231 participants (n = 199 females, n = 30 males, n = 2 non-binary) completed a cross-sectional online questionnaire, capturing quantitative data with the social appearance anxiety scale (SAAS), the shortened version of the coping inventory for stressful situations (CISS-21), and qualitative data from free-text comments and thematic content analysis. Respondents were also asked to provide additional free text comments in relation to the challenges faced and how these were managed.

Results

Content analysis revealed that males and females faced daily practical, social and emotional challenges and coped with them in several ways; with higher levels of social appearance anxiety associated with both higher perceived severity of skin condition and younger age. Males and females appeared equally as emotionally affected by living with a skin condition, with the only significant gender difference being females as significantly more likely to engage in avoidant coping behaviours than males.

Conclusions

Living with a skin condition presents daily practical, social, and psychological challenges for males and females that have the potential to impact on quality of life. Findings highlight the need for dermatological care to routinely address these issues, and psychosocial interventions must be made available to promote healthy coping with skin conditions.

Skin signs in eating disorders: a literature review

PURPOSE

To summarize and describe the available knowledge on dermatological manifestation of eating disorders: anorexia nervosa, bulimia nervosa, binge eating disorder and eating disorder not otherwise specified, diagnosed according to Diagnostic and Statistical Manual of Mental Disorders IV-TR and 5th edition.

METHODS

We searched in PubMed, Scopus and Web of Science databases from January 1, 1980 through May 1, 2020 for papers in English language on the skin manifestation of eating disorders. Results were screened using the PRISMA tool.

RESULTS

The study yielded 207 results. According with PRISMA guidelines, 26 papers were included in the review. More than 73% of screened papers (19/26) were case reports. Cross-sectional studies represented the 19.2% of screened papers (5/26). Each eligible study has been screened and analyzed.

CONCLUSION

Huge heterogeneity of skin signs of eating disorders were identified. The number of controlled studies available is very limited, and most papers of interest are case reports or narrative review articles. Larger, more methodologically rigorous studies to evaluate the presence of dermatological issue in eating disorder patients are needed.

LEVEL OF EVIDENCE

Level IV. Evidence obtained from multiple time series analysis such as case studies.

Psychodermatology - a case for sensitization of pharmacists in Mumbai, India

BACKGROUND

Though studies have looked at the attitudes of dermatologists towards psychodermatology, few have highlighted the attitudes of pharmacists towards these conditions.

OBJECTIVES

To study the knowledge, attitudes and practices of pharmacists towards the prescription of psychotropic medications to dermatology patients.

METHODS

This cross-sectional analysis included 80 pharmacists from Mumbai, India. We used an interviewer-administered questionnaire to collect information from pharmacists on their demographics, psychotropic medications in dermatological patients, knowledge about psychocutaneous conditions and comfort about dispensing these medications.

RESULTS

In our study, 37 (46%) of pharmacists received prescriptions of psychotropic drugs from dermatologists; however, 24 (30%) were not comfortable dispensing them. Sixty (75%) pharmacists felt that only psychiatrists should prescribe psychotropic drugs and 37 (46%) felt that they had a right to refuse to dispense prescribed medication; of these, 15 (19%) had actually refused to give medications to patients. Pharmacists who disagreed with the statement that 'the state of mind is associated with medical conditions', were more likely to discourage psychotropic prescription from dermatologists (29% vs 11%, P = 0.04). Pharmacists with experience of more than five years were significantly more likely to refuse to dispense medications (odds ratio: 5.14, 95% confidence interval: 1.02, 25.83; P = 0.047).

LIMITATIONS

We did not have a list of all pharmacists in Mumbai; thus, no sampling frame could be applied.

CONCLUSION

Pharmacists do comment on doctors' prescriptions, discourage certain medications and even refuse to dispense them based on their personal opinions. Since they are the last stop for patients between the doctor and the medication, their inclusion (in addition to dermatologists, psychiatrists and psychologists) in integrated awareness, training and care programs would improve the quality of care of patients with psychocutaneous disorders.

Psychodermatologic pathology in adolescents: findings from the Colombian National Mental Health Survey

Background Associations between mental health and dermatology have generated a new branch of study called psychodermatology, which includes relevant conditions to the adolescent population. However, there is limited research focusing on this field and this specific population. Objective To estimate the prevalence of dermatological pathologies in the Colombian adolescent population and their possible associations with mental health conditions. Methods We performed a secondary analysis of the Colombian National Mental Health Survey results. A representative sample of the adolescent Colombian population answered questions regarding dermatological conditions and mental health disorders. We estimated the prevalence and evaluated associations using the chi squared independence test. Results Of 1753 adolescents, 8.3% (CI95%=[6.8-10.1]) had dermatitis or skin allergies and 4.5% (CI95%=[3.3-6.1]) acne. For dermatitis, we found associations with age, education, and family dysfunction (p-Values=0.024; <0.001; 0.046 respectively). Acne was associated with age, sex, educational level, the number of social groups involved in, alcohol consumption, psychoactive substances use and previous violent experiences (respective p-Values=0.007; 0.004; 0.005; 0.036; 0.002; 0.003; 0.044). Regarding mental health, dermatological conditions were associated with depression, affective disorders, suicide attempt and suicide ideation. Conclusion Our results are the first to describe the prevalence of these disorders in Colombia. This is an exploratory study; nonetheless, it is of great value since it is the first to describe these associations in adolescents in a middle-income country, which should be considered during clinical examinations. Further longitudinal studies evaluating possible causal relationship between psychiatric and dermatological conditions are fundamental to establish causal links.

Management of psychocutaneous disorders: A practical approach for dermatologists

Psychodermatology is a growing specialty which is gaining momentum in different parts of the world. It focuses on the connection between skin and psyche. Psychocutaneous conditions are characterized by those disorders where stress is the key element in exacerbating skin conditions or flare ups of dermatoses like psoriasis and atopic dermatitis. There is a direct relationship of stress with the course, and prognosis of the skin disease. In some situations, there is no skin condition but the lesions are self-inflicted and such disorders are always associated with underlying psychopathology or psychological conflicts. Sometimes emotional problems are more prominent as a result of having skin disease, and the psychological consequences may be more severe than the physical symptoms. Management of these conditions require a combination of psychpharmacology, psychotherapy, and liaison clinics of psychiatry and dermatology. This review focuses on the common management approach which can be adopted by dermatologists in treating patients with psychodermatological disorders, improving doctor-patient relationship and therapeutic bond.
