This article investigates the limitations of Chat Generative Pre-trained Transformer (ChatGPT), a language model developed by OpenAI, as study tool in dermatology. The utilized ChatPDF, an application that integrates PDF files with ChatGPT, to generate American Board Dermatology Applied Exam (ABD-AE)-style questions from continuing medical education articles Journal Dermatology. A qualitative analysis was conducted two board-certified dermatologists, assessing accuracy, complexity, and...
Hair dye products constitute an important source of allergen exposure, and contribute importantly to allergic contact dermatitis in consumers hairdressers.To evaluate the presence potent sensitizers oxidative hair intended for home use on US market.Ingredient labels 107 dyes from 10 major brands were examined used assess prevalence substances known be sensitizers.One hundred six (99%) contained at least one sensitizer, average product (range 0-11). p-Phenylenediamine (PPD) was found 83...
Patch testing, a key diagnostic tool for allergic contact dermatitis, relies heavily on visual assessment of erythema, which is not as prominent or presents differently in skin color. To address this challenge, we used 3D camera and image processing software to analyze patch test reaction grades color patients. Here, present topographic photographs videos doubtful, 1+, 2+, 3+, irritant reactions highlight the infiltration edema through measurements relative height texture changes. By...
Abstract Background Patient‐reported triggers for atopic dermatitis ( AD ) flares include changes in ultraviolet irradiation, humidity and temperature. Objectives To identify the relationships between weather data healthcare utilization patients. Methods Using nationwide registries, clinic (1994–2012) hospital visits (1977–2012) treatment were calculated as well monthly totals of topical corticosteroid TCS (1996–2012) calcineurin inhibitor TCI prescriptions (2003–20012) filled by We averages...
Nickel is the most common allergen detected by patch testing in children. There an increasing number of cases children who have not had exposure to piercing. Although clinical relevance nickel test reactions sometimes uncertain, continued vigilance identify new sources this age group important. Recent case reports described allergic contact dermatitis following toys, but magnitude problem unknown.The aim study was evaluate and cobalt release from children's toys.We purchased 212 toys 18...
The risk of prenatal, obstetric and birth complications in mothers with atopic dermatitis (AD), along treatment use during pregnancy, is unknown.To examine the associations between AD describe dermatologic care received pregnancy.Mother-child pairs, which mother had a history AD, were identified through Danish Medical Birth Registry matched 1 : 10 non-AD pairs. Data on obtained linkage via nationwide registers. Multiple logistic regression was performed.We 668 births from 1997 2014 to women...
Summary Background Several studies have shown nickel and cobalt release from jewellery by using spot tests, but the metal composition of is largely unknown. Objectives To evaluate a large worldwide sample mainly inexpensive items, investigate nickel, lead subsample EN 1811:1998‐required methods. Methods A total 956 metallic components were examined with X‐ray fluorescence spectroscopy. 96 items purchased in U nited S tates investigated for use artificial sweat immersion plasma optical...
Cobalt was recently identified in a leather couch responsible for dermatitis. content/release the United States is unknown. We evaluated cobalt and investigated screening methods identifying leather.One hundred thirty-one swatches were screened with X-ray fluorescence (XRF) spectrometry indicator solution (CIS). Samples positive screens 1 negative control analyzed using inductively-coupled plasma mass (ICPMS).CIS showed that 5 of 131 samples contained cobalt, subsequently found to be between...
Background: China and Thailand produce large amounts of jewellery that are sold domestically abroad. Objective: To identify nickel release metal content in earrings purchased Thailand. Methods: A total 557 were randomly from vendors 11 markets located Beijing, Chengdu, Bangkok, Patong Beach, Hat Yai. Earrings subjected to dimethylglyoxime (DMG) tests 26 the DMG negative further evaluated qualitatively for major minor using X‐ray fluorescence spectrometry. Results: 314 Chinese (31.5%) 243...
Background. Nickel is widely used in coins; nickel may cause contact allergy and allergic dermatitis those who handle them. Objectives. To investigate alloy use, coin composition cobalt release for a worldwide selection of currently circulating coins. Materials methods. Eight hundred fifty coins 361 different denominations or issues from 52 countries were collected analysed with X‐ray fluorescence spectrometry spot tests. Results. Copper–nickel was the most frequently identified alloy, being...
