RESUMO
BACKGROUND AND OBJECTIVE: Body dysmorphic disorder (BDD) is a mental disorder that is difficult to diagnose, causes a lot of suffering and is more prevalent in dermatology patients than in the general population. Our objective was to screen for possible cases of BDD in patients with acne and to determine the prevalence according to DSM-IV and DSM-5 criteria, as well as to analyse the relationship between dermatological and sociodemographic variables. METHODS: A total of 245 patients diagnosed with acne in 11 dermatological centres in Spain were included in the study by members of the Aragon Psychodermatology Research Group and Spanish Research Group of Psychiatric Dermatology. We used the Body Dysmorphic Disorder Questionnaire (BDDQ) as a screening tool. RESULTS: In our sample, we obtained a prevalence for BDD of 10.6% (95% CI: 7.6-13.6%). The prevalence was the same with DSM-IV or DSM-5 criteria. Possible cases of BDD were predominantly women (P = 0.021), and 56% had non-inflammatory lesions vs. 30% of negative patients (P = 0.002). Positive patients as possible cases of BDD spent more than two hours on average a day worrying about their appearance. Most people only worried about one part of their body (86%), and in 95% of the cases, the part of their body that worried them was the face. The three most frequent compulsive behaviours in patients who screened positive for BDD were mirror checking (90.7%), camouflaging (79.1%) and using make-up (72.1%). CONCLUSIONS: As a consequence of the high prevalence of possible cases of BDD in patients with acne observed in our study, there is a need for dermatologists to screen for BDD so that they can be referred to a mental health unit to confirm the diagnosis and be offered treatment to reduce the progression of psychosocial deterioration and the development of comorbid disorders.

INTRODUCTION: Chronic scratching is common to many skin disorders. Being a female and presenting a high level of psychopathology are risk factors for chronic scratching. Yet, it is unclear why. Certain personality characteristics that are more prevalent in women are also known to influence emotional states (i.e. emotional tension). OBJECTIVE: The present study aims to explore whether these personality styles might help understand why gender and emotional distress are associated with scratching. MATERIAL AND METHODS: We compared the personality patterns of 103 patients (69.9% women) diagnosed with Lichen Simplex Chronicus, against a sample of healthy individuals. RESULTS: Significant differences were found in the personality styles of men and women with LSC. Women were more pessimistic, oriented to fulfil the needs of others, traditional, insecure, submissive, and reserved, with moderate (d=.43) to strong (d=.96) size effects ranges. Some of these differences, such as in traditionalism, dutifulness, other-orientation, and pessimism, were also observed when compared with healthy men and women, with small (d=.03) to moderate (d=.47) size effects ranges. CONCLUSIONS: These psychological factors may help explain the mechanisms underlying gender differences in chronic scratching, at least in Lichen Simplex Chronicus. The findings might open new avenues for research and treatment.

BACKGROUND AND OBJECTIVES: Positive immunostaining for the tumor suppressor protein p16 is associated with the presence of mucosal or αsubtypes of human papillomavirus (HPV) in cervical and genital squamous cell carcinoma (SCC). The aim of this study was to determine whether p16 immunostaining is also associated with mucosal HPV in extragenital SCC. MATERIAL AND METHODS: Paraffin sections of lesions located in the genital region (8 genital warts, 3 intraepidermal SCCs, and 7 invasive SCCs) and extragenital area (29 intraepidermal SCCs corresponding to Bowen disease and 10 invasive SCCs) were stained for p16 by immunohistochemistry. Mucosal HPV was detected by polymerase chain reaction (PCR). RESULTS: In the genital area, p16 immunostaining was negative in genital warts and positive in all 3 intraepidermal SCCs and 2 invasive SCCs (29%). Mucosal HPV was detected in 6 genital warts and 2 intraepidermal SCCs (100% after exclusion of 3 lesions that could not be analyzed by PCR) and in the 2 invasive SCCs that were positive for p16. In the extragenital area, 19 intraepidermal SCCs (95%) and 2 invasive SCCs (20%) were immunopositive for p16. Mucosal HPV was detected in 4 intraepidermal SCCs (p16 immunopositive) and 1 invasive SCC (p16 immunonegative). In intraepidermal SCCs, p16 immunostaining facilitated the identification of dermal microinfiltration or invasion of normal skin appendages. CONCLUSIONS: According to our results, unlike in genital SCCs, p16 immunopositivity is independent of the presence of HPV in extragenital SCCs. Compared with intraepidermal SCCs, the absence of p16 protein in invasive SCCs in the extragenital area would indicate progression of the disease.

Burning mouth syndrome is characterized by a painful burning or stinging sensation affecting the tongue or other areas of the mouth without obvious signs of an organic cause on physical examination. A burning mouth sensation can occur in several cutaneous or systemic diseases that must be ruled out prior to making a diagnosis of burning mouth syndrome, since this term is used exclusively to refer to idiopathic forms and is included within the cutaneous sensory disorders. In most cases, patients with burning mouth syndrome have accompanying psychologic or psychiatric conditions. Consequently, the syndrome has traditionally been included among the psychogenic dermatoses. However, it is currently unclear whether psychologic factors are a cause or a consequence of the syndrome, or whether each exacerbates the other. Recent studies propose the etiology to be neurologic, either neuropathic or related to taste.
