The Psychosocial Impact of Chronic Facial Dermatoses in Adults.

INTRODUCTION: Skin diseases have negative psychological and social consequences, especially when they are chronic and affect a visible area of the body, such as the face. OBJECTIVES: The purpose of this study is to investigate and compare the psychosocial impact of three common chronic dermatoses of the face: acne, rosacea, and seborrheic dermatitis. METHODS: The Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), and Social Appearance Anxiety Scale (SAAS) were used to compare acne, rosacea, and seborrheic dermatitis patients and healthy controls. The relationships between DLQI, HADS, and SAAS results were investigated, as well as their associations with disease duration and severity. RESULTS: The study included 166 acne patients, 134 rosacea patients, 120 seborrheic dermatitis patients, and 124 controls. The patient groups had significantly higher DLQI, HADS, and SAAS scores than the control group. Rosacea patients had the highest DLQI and SAAS scores, as well as the highest anxiety prevalence. Patients with seborrheic dermatitis had the highest rate of depression. The DLQI, HADS, and SAAS results were moderately correlated with each other, but their relationship with disease duration and severity was insignificant or weak at best. CONCLUSIONS: Chronic facial dermatoses have a detrimental impact on mood and quality of life. Although patients with acne, rosacea, and seborrheic dermatitis have distinct lesions, the outcomes in terms of quality of life, anxiety, and depression are largely similar. Furthermore, these patients report similar levels of social anxiety as a result of their overall appearance.

Novel mutation identified in the DDB2 gene in patients with xeroderma pigmentosum group-E.

BACKGROUND: Xeroderma pigmentosum (XP) is a rare photosensitive syndrome, which is divided into eight complementation groups (XP-A to XP-G and XPV) and characterized by skin cancers diagnosed at early age. A family of seven members (age range between 5 and 47 years) with carriers of the novel nonsense mutation that causes XP-E type were included in the current study. METHODS: DNA was isolated from peripheral blood samples of the proband, and cancer predisposition genes were sequenced with next-generation sequencing. The demographic features and the laboratory, clinical, and histopathological findings of patients were evaluated. RESULTS: In the proband, squamous cell carcinoma was first diagnosed in the right-eye cornea at the age of 13 years and then in the left-eye cornea at the age of 15 years. Later, the patient was diagnosed with basosquamous cell carcinoma on the dorsum of the nose at the age of 18 years. After genetic analysis, a novel nonsense c.1063C>T(p.Arg355Ter) pathogenic variation that causes XP-E type was detected as homozygous in the DDB2 gene of the proband and her siblings, 11 and 5 years of age, and as heterozygous in her parents and a 22-year-old brother. CONCLUSION: Because of the occurrence of early termination codon, truncated nonfunctional proteins or proteins with deleterious loss or gain-of-function activities are synthesized in nonsense mutation. Thus, to avoid the development of pathological lesions, it is important that such patients with nonsense mutation stay away from agents that might cause DNA damage and develop an appropriate lifestyle according to this condition.

Keratoconus Could Be Associated With Psoriasis: Novel Findings From a Comparative Study.

PURPOSE: To explore the relationship between keratoconus (KC) and psoriasis. METHODS: One hundred ten eyes of 55 patients with psoriasis (study group, SG) and 110 eyes of age-sex-matched 55 healthy volunteers (control group, CG) were included in the study. All cases underwent a detailed dermatological and ophthalmological examination including corneal topography. Moreover, Psoriasis Area and Severity Index (PASI) scoring of the patients was carried out in the SG. A thorough comparison of pachymetric, aberrometric, and topometric values between the groups was performed, and the results were interpreted. A χ test, Mann-Whitney U test, and Pearson correlation test were used for statistical assessment. RESULTS: Although the average Kmax (44.6 in the SG; 44.5 in the CG; P = 0.613) and Belin/Ambrósio enhanced ectasia total deviation value (1.34 in SG; 1.20 in CG; P = 0.880) were similar between the groups, the mean index of vertical asymmetry value in the SG (0.14 mm) was significantly higher than that in the CG (0.11 mm) (P = 0.041). Moreover, 28 eyes from 16 patients with psoriasis were found to be associated with KC because 26 of those 28 eyes were KC suspects and 2 of them were definite KC. A positive correlation was found among topometric parameters, especially between duration of the disease and PASI score. A negative correlation was discovered between topometric parameters and the early beginning of psoriasis. CONCLUSIONS: Serious changes in topography maps may occur in psoriatic patients. The changes were found to be more evident in the presence of a higher PASI score and the early beginning and longer duration of the disease. The results hinted a potential relationship between psoriasis and KC.
