“…Reports of self-inflicted dermatoses in patients with schizophrenia are uncommon [ 45 - 47 ]. Rather, most studies demonstrate an association between self-inflicted dermatoses and major depression, obsessive-compulsive disorder (OCD), and anxiety disorders [ 46 , 48 - 50 ]. The higher prevalence of self-inflicted dermatoses among patients with schizophrenia in this study, therefore, contradicts popular findings in the literature.…”

Background Psychodermatological disorders (PDs) and their associations with mental health problems are one of the most frequent research themes in dermatology outpatient settings. Surprisingly, very few studies have been conducted to evaluate PDs among patients with primary psychiatric conditions. As such, the relationship between preexisting psychiatric conditions and comorbid PDs is underrepresented in the literature. Objective This study examined the prevalence and distribution of PDs among adults with primary psychiatric conditions and determined their association with underlying psychiatric diagnoses. Methods We conducted a cross-sectional analysis at a tertiary health care facility in southwestern Nigeria. Comorbid PDs were identified and classified using preexisting classification systems. A bivariate analysis was conducted to determine the association between PDs and underlying psychiatric conditions. The level of statistical significance was set at P<.05. Results The study included 107 patients with mental health disorders, of whom 64 (59.8%) were female. The mean age of the patients was 40.73 (SD 13.08) years. A total of 75 (75/107, 70%) patients had at least one comorbid PD. The prevalence of PDs was highest in patients with affective disorders (15/20, 75%) and least in those with schizophrenia (45/66, 68%). PDs associated with delusions or hallucinations and somatoform symptoms were 9 and 13 times more frequent in patients with anxiety disorders compared to those with other psychiatric conditions (P=.01; odds ratio [OR] 9.88, 95% CI 1.67-58.34 and P=.003; OR 13.13, 95% CI 2.34-73.65), respectively. In contrast, patients with schizophrenia were significantly less likely to be diagnosed with dermatoses resulting from delusions or hallucinations (P=.002; OR 0.04, 95% CI 0.00-0.75). A weak but significant negative association was also found between psychophysiological PDs and anxiety disorders (ϕ=–0.236; P=.02). Conclusions This study provides important insights into the overwhelming burden of psychodermatological conditions in patients with mental health disorders and specific associations with underlying psychiatric diagnosis.

BACKGROUND Psychodermatoses and their associations with mental health problems are one of the most frequent research themes in dermatology out-patient settings. Surprisingly however, very few studies have been conducted to evaluate psychodermatoses among subjects with primary psychiatric disorders. As such, the relationship between pre-existing psychiatric disorders and co-morbid psychodermatoses are underrepresented in literature. OBJECTIVE Aims This study examined the prevalence and distribution spread of psychodermatoses among adults with primary psychiatric disorders and determined the association between psychodermatological disorders and underlying psychiatric diagnosis. METHODS A cross-sectional analytical study involving 107 adult psychiatric patients was conducted at a tertiary healthcare facility in Southwestern Nigeria. Co-morbid psychodermatological disorders (PDs) were identified and classified using pre-existing classification systems. Bivariate analysis was conducted to determine the association between psychodermatoses and underlying psychiatric disorders. The level of statistical significance was set at p < 0.05. RESULTS Seventy-five (70.1%) of mental-health patients had at least one co-morbid psychodermatoses. The prevalence of psychodermatoses was highest in patients with affective disorders (75%) and least in those with schizophrenia(68.2%). PDs resulting from delusions/hallucinations (PDDH) and somatoform PPDMS were 9 and 13 times more frequent in patients with anxiety disorders compared with other psychiatric disorders (p= 0.013 and 0.003 respectively) In contrast, patients with schizophrenia were significantly less likely to be diagnosed with PDDH (p=0.002) A weak but significant negative association was also found between psychophysiological PDs and anxiety disorders (phi = -0.236, p=0.015). CONCLUSIONS This study provides important insights into the overwhelming burden of psychodermatological conditions in mental health patients and specific associations with underlying psychiatric diagnosis.
