Pediatric Contact Dermatitis: A 10-Year Multicenter Retrospective Study.

Although allergic contact dermatitis (ACD) is relatively common in the adult and pediatric populations alike, few studies describe the special features of contact sensitization among the Israeli pediatric populations, none of them is multicenter. Our study aims to describe and analyze patch test results and trends in 4 tertiary care centers between 2012 and 2022. We assessed the results of 357 patch tests performed on children 0-18 years old between 2012 and 2022 in designated clinics in 4 tertiary medical centers.

Toothpaste allergy as a cause of cheilitis in Israeli patients.

Background: Allergic contact cheilitis may appear after exposure to different substances, including dental materials, toothpastes, cosmetics, foods and medications.

Objective: To compare the rate of toothpaste allergy between patients with and without cheilitis and to examine the yield of our proposed toothpaste patch test kit for use in patients with cheilitis.

Methods: A patch test kit containing 11 substances used in toothpastes was formed.
