Abstract
Background Dermatitis is one of the most common skin disorders across the world. Atopic dermatitis (AD) and contact dermatitis (CD) are its two primary types. Few studies have focused on the causal relationship between fluid intake and dermatitis. With an Mendelian Randomization (MR), this study investigated the potential causal effects of alcohol, coffee, tea, and water intake on the risk of AD and CD. Methods Utilizing genetic variants as instrumental variables (IVs), a two-sample MR analysis was implemented based on data from the UK Biobank and FinnGen r9 consortium. Fluid intake was categorized into alcohol, coffee, tea, and water intake. Causal estimates were analyzed through Inverse Variance Weighted (IVW), MR-Egger, and weighted median methods. Cochran's Q, MR-Egger intercept, and MR-PRESSO tests were conducted to assess potential heterogeneity and pleiotropy. Results Water intake exhibited a significant causal effect on raised CD risk (IVW OR = 2.92, 95% CI: 1.58-5.41, p = <0.01). Coffee intake was associated with increased CD risk (IVW OR = 2.16, 95% CI: 1.19-3.91, p = 0.01). Conversely, tea intake demonstrated a protective effect on AD risk (IVW OR = 0.71, 95% CI: 0.56-0.91, p = <0.01). Conclusion This MR study suggests a potential association where water and coffee intake may be linked to an elevated risk of CD, while tea intake may potentially have a mitigating effect on AD risk. Modifying fluid intake patterns could be a targeted approach for dermatitis prevention, emphasizing the need for additional longitudinal studies to validate and expand upon these findings.

Abstract
Purpose of Review This review highlights recent developments in the field of pediatric allergic contact dermatitis (ACD) and patch testing. We will review updates on the pathophysiology of contact dermatitis, discuss new contact allergens, explore the impact of dupilumab on patch testing, and provide pearls for the diagnosis and management of ACD in children. Recent Findings ACD is not a single immunologic phenomenon but rather has contributions from multiple inflammatory pathways. Emerging contact allergens include ingredients found in “slime” toys, glucose monitors and insulin pumps, and electronic equipment. Data thus far suggests that patch testing results are generally reliable in the face of concurrent dupilumab use. Summary ACD is likely underrecognized and underdiagnosed in pediatric patients, including infants and young children. Providers should keep patient-specific factors and emerging trends in mind when addressing suspected ACD, consider contact dermatitis when they encounter challenging cases of atypical, refractory, or chronic dermatitis, and feel comfortable performing patch testing in children.

Abstract
OBJECTIVE Newborn skincare influences levels of beneficial factors from vernix and vaginal secretions but also the emergence of potential skin pathogens. However, evidence-based national guidelines for newborn skincare do not exist, and actual hospital practices for newborn skincare have not been described. In this study, we test the hypothesis that US maternity hospitals follow differing policies with regard to newborn skincare. METHODS A 16-question survey querying skin care practices was distributed to nursery medical directors at the 109 US hospital members of the Better Outcomes through Research for Newborns network. Data from free text responses were coded by 2 study personnel. Survey responses were analyzed by using descriptive statistics and compared by region of the United States. RESULTS Delaying the first newborn bath by at least 6 hours is a practice followed by 87% of US hospitals surveyed. Discharging newborns without a bath was reported in 10% of hospitals and was more common for newborns born in nonacademic centers and on the West Coast. Procedures and products used for newborn skincare varied significantly. Parental education on tub immersion and soap use was also inconsistent and potentially contradictory between providers. Evidence cited by hospitals in forming their policies is scant. CONCLUSION In this study, we identify similar and strikingly different newborn skincare policies across a national network of US maternity hospitals. Research is needed to identify effects of differing skincare routines on skin integrity, infection rates, and childhood health outcomes to improve the evidence base for the care of newborn skin.

Abstract
Allergic contact dermatitis (ACD), a delayed hypersensitivity skin reaction to environmental allergens, has a prevalence that is similar in children and adults. However, diagnostic testing for ACD in pediatric populations accounts for less than one tenth of all patch tests. The relative infrequency of pediatric patch testing may be attributed to the difficulty in testing in this population, which includes a smaller surface area for patch test placement and maintaining cooperation during patch testing, especially in younger children. Diagnosis can be difficult in children because the appearance of ACD can mimic other common pediatric skin conditions, particularly atopic dermatitis and irritant contact dermatitis. Comprehensive history taking, guided by patient presentation, age group, and location of dermatitis, helps build clinical suspicion. Such clinical suspicion is one of the major reasons behind patch testing, with additional indications being recalcitrant dermatitis and dermatitis with atypical distribution. US pediatric data have shown the top allergens to be metals, fragrances, topical antibiotics, preservatives, and emollients. These trends are important to recognize to guide management and accurate diagnosis, because ACD tends to persist if the allergen is not identified and can affect patients' quality of life.

Abstract
PURPOSE OF REVIEW Contact dermatitis is an economically burdensome pediatric disease, and it is important to know the top allergens that have remained as top offenders for over the last decade. RECENT FINDINGS A comparative analysis of the 20-allergen screen was done against the current top 40 pediatric allergens, and it revealed that the 20-allergen screening series would have theoretically only captured 47.5% of the relevant contact allergens (52.5% failure to detect rate). In addition, the T.R.U.E. Test (SmartPractice, Phoenix, Arizona, USA) would have revealed 60% of the top 40 allergens (40% failure to detect rate). SUMMARY Patch testing in children has become a more common practice, and management requires the identification and avoidance of the offending allergen from the sensitized person's environment.
