AI Article Synopsis
- The study examined the link between stasis dermatitis (SD) and allergic contact dermatitis (ACD) in patients who underwent patch testing.
- Out of 38,723 patients studied, 303 were diagnosed with SD, with 46.7% also having ACD, indicating a significant association between the two conditions.
- Key allergens identified in SD patients included fragrance mix I and bacitracin, predominantly originating from personal care products and topical medications, highlighting the importance of patch testing for better diagnosis and treatment.
Article Abstract
Background: Few studies explored the relationship between stasis dermatitis (SD) and allergic contact dermatitis (ACD).
Objective: To examine trends, associations, and clinical relevance of ACD in patients referred for patch testing who had a final SD diagnosis.
Methods: Retrospective analysis from 2001 to 2016 of 38,723 patients from the North American Contact Dermatitis Group.
Results: After patch testing, 303 (0.7%) patients were diagnosed with SD; 46.7% had a concomitant diagnosis of ACD. Patients with vs. without a final SD diagnosis had similar proportions of ≥ 1 positive allergic reaction (59.7% vs. 64.7%; Chi-square, P = 0.0724) but higher odds of allergic reactions to fragrance mix I, bacitracin, quaternium-15, Myroxylon pereirae, benzalkonium chloride, ethyleneurea melamine formaldehyde, diazolidinyl urea, and propylene glycol. The most commonly relevant allergens in patients with final SD diagnosis were fragrance mix I, Myroxylon pereirae, bacitracin, quaternium-15, and formaldehyde. The most common allergen sources were personal care products, topical medications and other health aid products.
Conclusion: Nearly half of patients with a final SD diagnosis were also diagnosed with ACD, supporting the role of patch testing in select SD patients.

Patients suffering epilepsy caused by the gain-of-function mutants of the hKCNT1 potassium channels are drug refractory. In this study, we cloned a novel human KCNT1B channel isoform using the brain cDNA library and conducted patch-clamp and molecular docking analyses to characterize the pharmacological properties of the hKCNT1B channel using thirteen drugs. Among cinchona alkaloids, we found that hydroquinine exerted the strongest blocking effect on the hKCNT1B channel, especially the F313L mutant.

Introduction A subject of ongoing debate within the National Football League (NFL) community revolves around the comparative risk of anterior cruciate ligament (ACL) injuries on natural versus artificial turf field surfaces. There have been mixed results as to whether there is a difference in injury rates depending on the playing surface and what factors might play a role in affecting these rates. Methods This study aims to compare the incidence of in-game knee ligament tears in the NFL during the 2020-2023 seasons.

Introduction: Autism spectrum disorder (ASD) represents a multifaceted set of neurodevelopmental conditions marked by social deficits and repetitive behaviors. Astragaloside IV (ASIV), a natural compound derived from the traditional Chinese herb Astragali Radix, exhibits robust neuroprotective effects. However, whether ASIV can ameliorate behavioral deficits in ASD remains unknown.

Toluene-2,5-diamine sulfate (PTDS), also known as toluene diamine sulfate or 2,5-diaminotoluene sulfate, is an aromatic amine that can be used as a paraphenylenediamine (PPD) hair dye alternative. Patients may develop contact allergy to PTDS, and it is often omitted from standard patch test screening series, possibly leading to underdiagnosis. The American Contact Dermatitis Society named PTDS the Allergen of the Year for 2025, aiming to raise awareness of its dual role as both an allergen and an alternative for some PPD-allergic individuals.
