The incidence of allergic contact dermatitis (ACD) due to personal care products is rising in parallel with increasing product availability and consumer interest. Hair products specifically represent a significant source of potential allergens, including preservatives, surfactants, emulsifiers, fragrances, adhesives, and dyes. ACD due to hair care products can present as dermatitis in the distinctive "rinse-off" distribution, involving the neck, eyelids, and lateral face in addition to the scalp. Herein, the authors review ingredients in hair care products that can cause ACD and practical tips for allergen identification.

Background: Higher health care utilization has been proven among US children with eczema than those without, but disparities may exist among sociodemographic subgroups. Objective: To determine health care utilization trends among children with eczema across sociodemographic factors. Methods: We included children (0-17 years old) from the US National Health Interview Survey 2006-2018. We calculated the survey-weighted health care utilization by determining proportion of children attending a well-child checkup, seen by a medical specialist, and seen by a mental health professional in the previous 12 months for children with and without eczema, by race (white, black, American Indian/Alaska Native, Asian, and multiracial), Hispanic ethnicity (yes/no), age (0-5, 6-10, 11-17), and gender (male/female) subgroups using SPSS complex samples. Joinpoint regression was used to estimate piecewise log-linear trends in the survey-weighted prevalence, annual percentage change, and disparities between subgroups. Results: We included 149,379 children-there was higher health care utilization in children with eczema than those without. However, when comparing the average annual percentage change (AAPC), white children had a significantly higher AAPC of "attending a well-child checkup" than black children. In addition, only white children showed a significantly increasing trend in being "seen by a medical specialist," whereas all other minority race subgroups had stagnant trends. For those "seen by a mental health professional," there were increasing trends only in the male and non-Hispanic subgroups out of all the sociodemographic subgroups. Conclusion: Improving awareness among primary care physicians to refer children with moderate-to-severe eczema to medical specialists (eg, allergists, dermatologists, and mental health/attention-deficit/hyperactivity disorder professionals) when necessary could improve quality of life and reduce emergency department visits-especially among minority race, Hispanic, and female children.

Background: Contact dermatitis is a common condition in the general population, with a global prevalence of 20%. It is an inflammatory skin disease that is classified as irritant contact dermatitis (80%) and allergic contact dermatitis (ACD) (20%). In addition, it is the most common presentation of occupational dermatoses and is one of the primary reasons for seeking medical attention among military personnel. Only few studies have compared the characteristics of contact dermatitis in soldiers and civilians. Objective: To compare the characteristics of ACD between civilians and soldiers. Methods: This large retrospective study was conducted in Israel and involved 1800 civilians and 750 soldiers with suspected ACD. All patients underwent relevant patch tests based on their clinical presentation and medical history. Results: At least 1 positive allergic reaction was found in 382 civilians (21.22%) and 208 soldiers (27.73%) (nonsignificant). Moreover, 69 civilians (18.06%) and 61 soldiers (29.32%) had at least 1 positive occupational allergic reaction (P < 0.05). Widespread dermatitis was significantly more common among soldiers. The most frequent occupations among civilians with positive allergic reactions were hairdressers/beauticians. "Professional, technical, and managerial occupations" were the most frequent categories among soldiers (24.6%), with computing professionals being the most common occupation (46.67%). Conclusion: Military personnel and civilians have different characteristics associated with ACD. Therefore, considering these characteristics before placement in a workplace can help prevent ACD.

Background: Patch testing is gold standard for identifying the source of allergic contact dermatitis (ACD). Objective: To report patch testing results from the Massachusetts General Hospital (MGH) Occupational and Contact Dermatitis Clinic from 2017 to 2022. Methods: Retrospective analysis of patients referred to MGH for patch testing, 2017-2022. Results: In total, 1438 patients were included. At least 1 positive patch test (PPT) reaction was observed in 1168 (81.2%) patients and at least 1 relevant PPT reaction was observed in 1087 (75.6%) patients. The most common allergen with a PPT was nickel (21.5%), followed by hydroperoxides of linalool (20.4%) and balsam of Peru (11.5%). Sensitization rates statistically increased over time for propylene glycol and decreased for 12 other allergens (all P values <0.0004). Limitations: Retrospective design, single institution tertiary referral population, and variations in allergens and suppliers across the study period. Conclusion: The field of ACD is constantly evolving. Regular analysis of patch test data is crucial to identify emerging and diminishing contact allergen trends.
