Acne results in higher anxiety in adolescent girls. Although acne and moderate/severe acne are more common in adolescent boys, the severity of acne was found to be similar in boys and girls with acne. Adolescent girls are more vulnerable than boys to the negative psychological effects of acne.
Background: Psychiatric comorbidity in patients with skin disorders has been reported. Objective: To find out the prevalence of psychiatric disorders in dermatology outpatients and to investigate the factors that affect the psychiatric symptoms. Methods: 256 patients attending our dermatology outpatient clinic completed a 12-item General Health Questionnaire (GHQ) following their dermatologic examination. A standardized personal interview was performed to establish a psychiatric diagnosis in patients sampled by using a stratified random sampling method. Results: The prevalence of psychiatric disorders was found to be 33.4% in the study group. The mean of the total GHQ scores of the sample group (n = 256 patients) was 3.656. The duration of the dermatologic complaints, sex of the subjects, localization of the lesions, and dermatologic diagnosis did not affect the total GHQ scores of the patients. Conclusion: Psychiatric comorbidity in 33.4% of the dermatology outpatients indicates the need for considering emotional factors for an effective management of the cutaneous disorders.
SummaryBackgroundPsoriasis is an inflammatory disease characterized by increased squamous cell proliferation and impaired differentiation. Vitamin D, Calcitriol, and its analogues are successfully used for psoriasis therapy. However, it is unknown why some psoriasis patients are resistant to Vitamin D therapy. Vitamin D mediates its activity by a nuclear receptor. It is suggested that polymorphisms and haplotypes in the VDR gene may explain the differences in response to vitamin D therapy.Material/MethodsIn this study, 102 psoriasis patients and 102 healthy controls were studied for VDR gene polymorphisms. The Fok I, Bsm I, Apa I and Taq I polymorphisms were examined by PCR-RFLP, and 50 subjects received vitamin D therapy to evaluate the association between VDR gene polymorphisms and response to vitamin D therapy. Existence of cutting site is shown by capital letters, and lack was shown by lower case. The haplotypes were analysed by CHAPLIN.ResultsThere was significant difference in allele frequency of T and genotype frequency of Tt between cases and controls (p values 0.038 and 0.04, respectively). The Aa and bb genotypes were significantly higher in early onset than late onset psoriasis (p values 0.008 and 0.04, respectively). The genotypes Ff, ff and TT are significantly different between vitamin D3 therapy responders and non-responders (p values 0.04, 0.0001, 0.009, respectively). To the best of our knowledge, this is the first report showing importance of VDR gene haplotypes in psoriasis, the significance of the Wald and LR (Likelihood Ratio) statistics (p=0,0042) suggest that FfBbAatt is a disease-susceptibility haplotype.ConclusionsHaplotype analysis is a recent and commonly used method in genetic association studies. Our results reveal a previously unidentified susceptibility haplotype and indicate that certain haplotypes are important in the resistance to vitamin D3 therapy and the onset of psoriasis. The haplotypes can give valuable data where genotypes unable to do.
LP may cause ocular surface changes and reduction in tear production, therefore it seems reasonable to evaluate these patients for symptoms and signs of dry-eye disease. We consider that LP should be included in the differential diagnosis of dry-eye disease, as this has important therapeutic and prognostic implications.
There is convincing evidence that vitiligo is a systemic disorder influencing the whole pigmentary system, including melanocytes in the inner ear. Cochlear melanocytes and also melanin-containing cellular elements of the auditory system may be affected in vitiligo and interfere with the conduction of action potentials. We conducted a prospective clinical trial to determine hearing status and auditory evoked potentials in 50 patients affected by vitiligo and compared the results with those of 50 healthy controls. I, III, V latencies and amplitudes and I-III, III-V, I-V interpeak latencies were compared with each group. Statistical evaluation was accomplished using the t-test. With the exception of two subjects, all patients demonstrated normal audiological results. No statistically significant difference was noted between the study group and controls in regard to latencies, interpeak latencies and amplitudes. We conclude that auditory investigations supported by postmortem histopathological studies of the inner ear and brainstem may provide more accurate knowledge in vitiligo patients.
Background: Studies on nickel patch test reactivity and reproducibility of positive tests at different points of the menstrual cycle are heterogeneous. Objective: To investigate if non-reproducibilities of positive nickel sulphate patch tests in the two different phases of ovulatory menstrual cycles with the endocrine evidence of luteal phase adequacy are statistically different. Methods: 15 women (group 1) with positive Finn chamber® nickel patch test results in the follicular phase of the ovulatory cycle and 13 women (group 2) with positive Finn chamber nickel patch test results in the luteal phase of the ovulatory cycle were tested again in the counter-phases of their ovulatory cycle, with a scheduled interval of 6 weeks following the first tests. Reproducibilities of the tests in the two groups were evaluated statistically. Results: 3 of the positive test results in group 1 (20%) and 2 of the positive test results in group 2 (15.4%) were non-reproducible. The difference was not statistically significant. Conclusion: The reproducibility of positive Finn chamber nickel patch tests does not seem to be affected by the changes in the follicular and luteal phases of the ovulatory cycle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
