Role of acrylates in the development of contact dermatitis in diabetic patients-A Polish dermatology tertiary centre experience.

BACKGROUND: In recent years, an increasing number of contact dermatitis cases triggered by acrylates contained in diabetes medical devices have been reported. Acrylates seem to play a major role in the development of irritant contact dermatitis and allergic contact dermatitis (ACD) in diabetic patients. OBJECTIVES: To study a group of patients with contact dermatitis caused by diabetes medical devices with a focus on acrylates as possible allergens responsible for contact dermatitis. PATIENTS AND METHODS: Fifteen patients with diabetes mellitus type 1 and contact dermatitis from diabetic devices were patch tested to 25 acrylate allergens. RESULTS: Three patients (20%) reacted to the following allergens: three patients reacted to isobornyl acrylate (IBOA) and one of them additionally to 2-hydroxyethyl acrylate (2-HEA); results were of clinical relevance. All three patients were using insulin pumps and glucose sensors (GS)-in one patient contact dermatitis was towards the insulin pump and the GS, in one patient only towards the insulin pump and in one patient only towards the GS. Twelve patients (80%) did not show any skin reaction towards the allergens tested. CONCLUSION: A majority of diabetic patients showed no reactions towards any acrylate allergen tested; yet, the presence of untested allergens must be kept in mind. IBOA proved to be a cause of ACD in diabetes patients. 2-HEA might be another culprit allergen, but its presence in the devices must first be confirmed.

Contact Dermatitis to Diabetes Medical Devices.

Skin adverse reactions to diabetes medical devices have been reported frequently over recent years. Adhesives attaching glucose sensors and continuous insulin infusion sets to the skin are proven to cause both allergic contact dermatitis and irritant contact dermatitis in patients with diabetes mellitus. Several allergens contained in adhesives and/or parts of medical devices are documented to cause allergic contact dermatitis, with acrylate chemicals being the most common culprit-especially isobornyl acrylate (IBOA), but also 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate or cyanoacrylates. Epoxy resin, colophonium and nickel were also identified as causative allergens. However, repetitive occlusion, maceration of the skin and resulting disruption of the skin barrier seem to have an impact on the development of skin lesions as well. The purpose of this study is to highlight the burden of contact dermatitis triggered by diabetes medical devices and to show possible mechanisms responsible for the development of contact dermatitis in a group of diabetic patients.

Is There a Need to Educate Patients with Atopic Dermatitis in Baseline Therapy?

INTRODUCTION: The baseline therapy of atopic dermatitis (AD) includes emollient therapy, prevention of triggering factors and proper patients' education. Appropriate level of education about AD among patients is crucial for successful treatment of the disease. AIMS: To compare and evaluate the level of knowledge about baseline therapy in atopic dermatitis (AD) between the adults with AD and the parents of children with AD. MATERIALS AND METHODS: Adult patients with AD (n=180) and parents of children with AD (n=106) completed an original questionnaire covering issues of emollient therapy and bathing. For statistical comparison a chi - square test was used with significance level of 0,05. RESULTS: With significance level of 0,05, the chi - square test showed a statistically significant difference comparing both groups. 52,38% adults and 68,73% parents proved to know the principles of basic therapy (p<0,05). 55,00% adults and 50,00% parents have not been informed how to apply emollients appropriately (p>=0,05). 75,56% and 74,53%, respectively, seek additional education about it (p>=0,05). 63,89% adults and 49,06% parents have not been informed about the principles of bathing (p<0,05). 70,00% and 74,54%, respectively, expect more comprehensive explanation of bathing rules (p>=0,05). CONCLUSIONS: Adults with AD have lesser knowledge about baseline therapy than parents of children with AD. Both groups express a very strong need for education about baseline therapy in AD.

Contributors to Preterm Birth: Data from a Single Polish Perinatal Center.

Preterm birth may result from overlapping causes including maternal age, health, previous obstetric history and a variety of social factors. We aimed to identify factors contributing to preterm birth in respect to new social and environmental changes in the reproductive patterns. Our cross-sectional study included 495 mother-infant pairs and was based on maternal self-reporting in an originally developed questionnaire. Neonates were divided into two groups: 72 premature babies (study group) and 423 full-term babies (control group). We analyzed maternal, sociodemographic and economic characteristics, habits, chronic diseases, previous obstetric history and pregnancy complications. For statistical analysis, Pearson's Chi-squared independence test was used with a statistical significance level of 0.05. Preterm births were more common among mothers living in villages (p < 0.001) and with lower education level (p = 0.01). Premature births were also positively associated with mothers who were running their own businesses (p = 0.031). Mothers with a history of previous miscarriages gave birth at a significantly older age (p < 0.001). The most frequent pregnancy complications were hypothyroidism (41.4%), pregestational and gestational diabetes mellitus (DM; 17.8%) and hypertension (8.1%). Pregestational DM significantly influenced the occurrence of prematurity (p < 0.05). Pregestational DM, being professionally active, a lower education level and living outside cities are important risk factors of prematurity.
