86; 95% CI, 0.22-1.49). Among children with AD, higher CIS scores were notably associated with male sex, older age, lower household income, public insurance, and comorbid depression and anxiety.

AD was associated with behavioral and functional impairment, similar to psoriasis and other common chronic conditions. There are significant sociodemographic differences in CIS scores.

Mercapto compounds are a category of rubber accelerators that may cause allergic contact dermatitis. This study characterizes patch test reactions to mercaptobenzothiazole (MBT) and mercapto mix (MM) in a large North American population.

The 1994-2016 North American Contact Dermatitis Group screening series data were analyzed. Patients with allergic reactions to either MBT or MM (mercapto+) were included. The following characteristics were analyzed strength of reaction, clinical and occupational relevance, coreactivity with other rubber accelerators, and sources of exposure.

A total of 49,795 patients were tested to mercapto compounds from 1994 to 2016; 633 (1.3%) had positive reactions to MBT and/or MM. The frequency to both MBT and MM significantly decreased over time (P < 0.0001). Mercapto+ patients were significantly more likely to be male, have occupationally related skin disease, and report involvement of the hands and/or feet (P < 0.0001). They were significantly less likely to have face, scalp/ears/neck, or trunk involvement (P ≤ 0.0001). There was significant coreactivity with carba mix (23.4%) and thiuram mix (32.5%). Mercaptobenzothiazole and MM reactions were frequently clinically (81.7% and 83.5%, respectively) and occupationally relevant (29.8% and 33.4%, respectively). Gloves were the most common source (31.3% and 30.9%, respectively).

Patch test positivity to mercapto compounds significantly decreased from 1994 to 2016 but remains clinically and occupationally relevant.

Allergic contact dermatitis (ACD) can exist in the setting of other dermatologic conditions. It is known that the treatment of these conditions can cause ACD, increasing both diagnostic and treatment difficulty.

The aim of this study was to determine the frequency of common dermatologic conditions in the setting of ACD and in specific patient populations.

A retrospective database study was completed using Truven Health to collect information on patch-tested ACD patients. Demographics and diagnostic information were retrieved. Of those with ACD, the presence of 15 dermatologic diagnoses was investigated. Subanalyses were conducted for each condition, including International Classification of Diseases, 10th Revision code specificity, demographics, and diagnostic information.

A total of 6380 patients (76.83% female) were given a diagnosis of ACD via patch testing. Of those with concomitant disease, those most common include atopic dermatitis (23.98%), urticaria (16.69%), and acne (11.51%). Eight of the concomitant conditions were found to have statistical significance in comparing the average age of ACD diagnosis with the selected diagnoses (α = 0.05).

Common dermatologic diseases can exist concomitantly with ACD, many of which can be treated by compounds that precipitate or worsen preexisting ACD. The average age of the diagnosis varies from concomitant diagnoses, which can contribute to difficulty in ACD diagnosis and treatment.

Both insulin pumps and glucose monitors are becoming increasingly convenient, long-lasting, and discrete for patients, but this often requires the use of strong external cutaneous adhesives and increased contact time with the skin. As a consequence, these devices have been associated with a variety of dermatologic reactions, namely, irritant and allergic contact dermatitis. Some of these reactions can be severe, precluding the use of these devices, which puts patients’ long-term health at risk. Herein, we review the history of diabetic devices and reported cutaneous reactions to diabetic devices and commonly cited allergens.

Isothiazolinones are commonly used preservatives, which may cause allergic contact dermatitis. The Lovibond Isothiazolinone Test Kit (LITK) has been reported to successfully identify clinically relevant, occult isothiazolinones in patient personal care products.

The aim of the study was to analyze dish soaps and personal care products that do not declare isothiazolinones (“no-ISO”) for the presence of isothiazolinones via 2 methods LITK and ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).

No-ISO dish soaps (n = 9), a convenience sample of patient products (n = 6), and controls (positive [isothiazolinone declared], n = 5; negative, n = 2) were tested with LITK (X3) and UHPLC-MS/MS.

Several no-ISO dish soaps and personal products were positive for isothiazolinones (LITK, n = 12; UHPLC-MS/MS, n = 3). Ultrahigh-performance liquid chromatography-tandem mass spectrometry specifically identified methylisothiazolinone alone in 1 no-ISO dish soap, methylchloroisothiazolinone in another, and both in a third. Using UHPLC-MS/MS as the criterion standard, we observed the accuracy of LITK for 9 dish soaps was poor (sensitivity, 66.7%; specificity, 20%) and very poor for 6 personal care products (sensitivity, 0%; specificity, 0%).

Personal products may contain undeclared isothiazolinones. The current study found that LITK had poor accuracy for testing dish soap and personal care products. Selleckchem TP0427736 Clinicians should be aware of these factors when managing patients with contact allergy to isothiazolinones.
