The Prevalence and Clinical Features of Body Dysmorphic Disorder Among Dermatology Patients in the Eastern Province of Saudi Arabia

Background and objective Body dysmorphic disorder (BDD), which affects 1.7% to 2.4% of people worldwide, is usually encountered for the first time by nonpsychiatric physicians. Up to 37% of cases have been documented in dermatology clinics. This study aims to estimate the prevalence of BDD among Saudis attending dermatology clinics because the literature is lacking in this field, especially in the Eastern Province. Methods This is a cross-sectional study, conducted in 2023. A total of 412 Saudi Eastern Province residents, aged 18 years and older, were included in the study and given a self-administered web-based questionnaire. The study uses the Body Dysmorphic Disorder Questionnaire as one of its three primary measurements, together with sociodemographic data, and dermatological and previous psychological histories. Results A total of 412 participants were enrolled in this study. Of the total sample, 64.5% had more than one skin condition, with the rest having only one one. The most received cosmetic treatment in this study was topical agents. It was estimated that the prevalence of BDD is 9.5% among the studied population. However, it was found that there are no significantly associated factors with the prevalence of BDD. Conclusions This study reports a prevalence of 9.5% among people visiting dermatological clinics. The prevalence is alarming, which emphasizes the importance of enhancing the awareness of BDD among dermatologists and developing certain guidelines to identify and refer these patients to mental health professionals.

Update on Diagnosis and Management of Onychophagia and Onychotillomania

Onychophagia (nail biting) and onychotillomania (nail picking) are chronic nail conditions categorized as body-focused repetitive behavior (BFRB) disorders. Due to a limited awareness of their clinical presentations, embarrassment on the part of patients, and/or comorbid psychiatric conditions, these conditions are frequently underrecognized and misdiagnosed. This article reviews the prevalence, etiology, diagnostic criteria, historical and physical exam findings, and treatment options for these conditions. The PubMed/MEDLINE database was searched for relevant articles. Onychophagia and onychotillomania are complex disorders necessitating a detailed patient history and physical examination and a multidisciplinary treatment approach for successful diagnosis and management. Due to the dearth of clinical trials for treatment of nail biting and nail picking, large clinical trials are necessary to establish standardized therapies.

Pediatric Onychophagia: A Survey-Based Study of Prevalence, Etiologies, and Co-Morbidities

BACKGROUND

Onychophagia, defined as habitual nail biting, is a common disorder affecting 6-45% of the population and is more prevalent in children.

OBJECTIVES

Our primary objective was to determine the prevalence of nail biting in the pediatric population. Secondary objectives were to assess the presence of psychiatric co-morbidities associated with nail biting, and the effect of treatment on nail biting.

METHODS

An anonymous voluntary survey was administered to participants at an outpatient academic pediatric clinic at Weill Cornell Medicine. Age, sex, psychiatric diagnosis, treatment sought, family history, and frequency of nail biting were analyzed across 282 enrolled patients aged 3-21 years. One patient was subsequently excluded due to incomplete data.

RESULTS

Of 281 patients, 101 (37%) reported past or present nail biting lasting more than a month. Median age of onset was 5 years old (range 1-13 years). A significantly higher percentage of biters (18%; 19/104) than non-biters (6%; 11/177) were diagnosed with a psychiatric disorder (p < 0.01). Amongst biters, concurrent fingernail and toenail involvement was much less common (12%; 12/104) than that of fingernails alone (88%; 92/104). However, the ratio of fingernail and toenail biters to fingernail biters alone was greater in those with psychiatric diagnosis (0.36) than without (0.09) (p = 0.07).

CONCLUSIONS

Our study highlights behavioral patterns as well as familial, psychiatric, and other factors associated with pediatric nail biting. Familiarity with such factors, the clinical presentation of onychophagia, and available treatment options may aid in reducing its severity in affected patients and overall prevalence.
