Assessment of patch test results carried out during ten years in a city in southern Brazil

Abstract

BackgroundContact dermatitis affects up to 20% of the population. Patch testing for contact allergy may be needed to confirm the diagnosis.ObjectivesTo describe and discuss the results of patch tests performed in a city in southern Brazil.MethodsA cross-sectional analysis was performed on all skin test results over ten years. Variables such as gender, age at the time of testing, and test results were evaluated. Triggering factors, duration of complain, and previous medications used related to the clinical history were retrieved for some patients by reviewing their medical records.ResultsThe sample was composed of 539 patch tests, of which 411 (76.2%) were from women. The age of the tested subjects ranged from 5 to 87 years. The prevalence of positive reactions in the patch tests was 391 (72.5%). The most prevalent positive reaction was to nickel sulfate (196; 36.4%), which had statistical significance when associated with female gender (p<0,001).Study limitationsDatabase obtained through secondary sources (the reports of the exams and the medical records), occurring the incomplete registration of some information.ConclusionsData analysis at the local level is important to define preventive policies.

Effects of slime toy poisoning in children and teenagers

“…In addition, the authors claim that females have higher exposure to allergenic substances and, in general, they are more tempted to seek medical care than males. 41 The limitations of this narrative review are mainly related to the reduced number of studies on the current literature reporting cases of skin reactions associated with slime in children and adolescents. Indeed, the present review was based on data collected from few case reports published in scientific database; perhaps, a higher incidence might be present.…”

Contact Allergy—Emerging Allergens and Public Health Impact

“…In some countries, limitations of the health system or health services offered may also limit the extent of patch testing. Consequently, data from these countries is scarce, e.g., from Nigeria [325], Romania [326], or remote areas of Brazil [327]. However, not only for a better global overview but-as written in the latter publication-to define preventive policies data analysis at the local level, such data are important [327].…”

While existing contact allergy may not necessarily lead to ACD if the allergen(s) can be sufficiently avoided, such avoidance often proves difficult.…”

Kontaktallergien – Neu aufkommende Allergene und Auswirkungen für das Gesundheitswesen

“…Aus diesen Ländern liegen folglich nur wenige Daten vor, z. B. aus Nigeria [325], Rumänien [326] oder entlegenen Regionen Brasiliens [327]. Doch nicht nur für einen besseren globalen Überblick, sondern – wie auch in der letztgenannten Publikation steht – auch für die Ausarbeitung von Präventivmaßnahmen ist die Auswertung von Daten auf lokaler Ebene wichtig [327].…”

Eine bestehende Kontaktallergie muss zwar nicht zwingend zu einer ACD führen, wenn das/die Allergen(e) in ausreichendem Maße gemieden werden können, doch oft erweist sich diese Vermeidung als schwierig.…”
