Atopic dermatitis (AD) is a frequent and burdensome disease. The objectives of this study were (1) to assess the willingness to pay (WTP) and quality of life (Qol) in AD patients and (2) to compare the results with data on other chronic skin diseases. To collect data, a non-interventional, cross-sectional nationwide postal survey on adult patients with clinically diagnosed AD was performed; socio-demographic data, clinical features/symptoms, WTP and QoL were recorded. WTP was assessed in three different approaches, including relative and absolute figures. Data from n = 384 AD patients (mean age 42.0, range 18-92, 69.8 % female) were analyzed. WTP for complete healing was on median
Rosacea patients show a moderate WTP and average QoL reduction is mild. WTP proved to be a valid tool to assess patients' burden of disease. Patient education and the development of effective treatment options might still improve patients' satisfaction.
Nail involvement in psoriasis is common and mostly occurs with other lesions but can also occur alone. Besides psychosocial and aesthetic impairments, patients often complain about functional impairment. Nail psoriasis is a predictor for more severe psoriasis, decreased quality of life, and a higher risk for the development of psoriatic arthritis. Onychomycosis and other differential diagnoses should be excluded prior to treatment. This article presents an overview of different clinical appearances of nail psoriasis, the essential diagnostic assessment before treatment, important differential diagnoses, and published data on treatment options for nail psoriasis.
In many countries, utility measures are required for allocation decisions. Unlike the EuroQoL-5D (EQ-5D), the dermatology life quality index (DLQI) has not been developed for the derivation of utilities. Purpose of this study was to develop and test an algorithm for the transformation of DLQI scores into utilities. Pre-existing data of two cross-sectional studies (for development, n = 1,511; for cross-validation n = 2,009) of German psoriasis patients were reanalyzed. Both EQ-5D global score and EQ-5D visual analogue scale (VAS) were used as utility measures. Correlations were computed to identify predictors of EQ-5D utilities. Linear stepwise regressions were conducted using DLQI and further possible predictors to find the optimal mapping algorithm. Using only DLQI as predictor resulted in coefficients of determination of r (2) = 0.235 (EQ-5D global score) and r (2) = 0.242 (EQ-5D VAS). In the final algorithm, seven predictors were included which correctly predicted EQ-5D VAS for 60.4 % (development database) and 60.8 % of all patients (cross-validation database) within a range of ±15 units. The algorithm explained 31.3 % of the EQ-5D variance in the development database and 26.8 % in the cross-validation database. In conclusion, mapping of DLQI on EQ-5D in psoriasis patients has severe limitations in validity and clinical relevance.
Recurrent vulvovaginal candidosis is a frequent disease with a serious impact on women's quality of life. Mostly, recurrences are caused by identical Candida strains suggesting C. albicans persistence in the female anogenital area. Objectives of the presented work were to identify the site of C. albicans persistence, to determine clinical symptoms and signs related to C. albicans positive vulvar cultures and to introduce a new therapeutic approach in women with RVVC. Women with an acute, culture-confirmed episode of RVVC at time of visit were included in this prospective case series. Swabs were obtained from both vagina and inter-labial sulcus. Women received a combined 20-day regimen of 100 mg oral fluconazole and ciclopiroxolamin cream topically. Follow-up visits were at 3, 6, 9 and 12 months. Of 139 women, 105 (76%) had at least one C. albicans positive culture from the external vulva. Vulvar positive cultures correlated with pruritus (OR 5.4; P < 0.001), vulvar edema (OR 3.8; P = 0.03) and fissures (OR 2.4; P = 0.03). Recurrence rates were 27%, 33% and 34% (at 6, 9, 12 months, respectively). The external vulva appears to represent a site of C. albicans persistence and source of endogenous re-infection in patients with RVVC. The combined treatment compared favorably with published fluconazole maintenance regimens.
Allergic diseases are a common, often burdensome problem in the German population, but nevertheless the medical treatment of people affected is still insufficient. The proportion of patients receiving sublingual immune therapy as causal treatment is comparatively low. Active steps are needed to improve the utilization behavior of patients, e. g. to take advice of an allergy specialist.
Background: The antifungal activity of coriander oil has already been demonstrated in vitro. Objective: Evaluation of the efficacy and tolerability of 6% coriander oil in unguentum leniens in the treatment of interdigital tinea pedis. Methods: Half-side comparative pilot study on subjects with symmetric, bilateral interdigital tinea pedis. Active drug and placebo control were applied twice daily on the affected areas, and follow-up visits were performed on days 14 and 28. Results: 40 participants (mean age 52.5 years, 60% male) were included in the study. For 6% coriander oil in unguentum leniens, a highly significant improvement of the clinical signs (p < 0.0001) was observed during the entire observation period; the number of positive fungal cultures also tended to decrease (p = 0.0654). The tolerability of the tested substances was good. Conclusion: Coriander oil is effective and well tolerated in the treatment of interdigital tinea pedis.
Covering the whole spectrum of dermatology, the dermatology departments of German university medical centers show extraordinary performances in both patient care and scientific research. They considerably contribute to the overall performance and the economic outcome of the German university medical centers and are an integral part of these institutions.
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.
