BACKGROUND AND OBJECTIVES Contact allergy is associated with a significant morbidity all over the world. This study was performed to investigate the pattern of sensitization by contact allergens in the local population. DESIGN AND SETTING Retrospective study to investigate patch test reactivity among patients with clinical diagnosis of contact dermatitis who were referred to the allergy clini...

BACKGROUND The standard assay for the clinical detection of contact allergy against nickel is the patch test. For research purposes, the in vitro lymphocyte transformation test (LTT) is mostly applied. However, the in vivo application of allergens includes the potential of sensitization, whereas the LTT demands 6 days of cell culture and radioactive labelling procedures. OBJECTIVE The purpose...

Allergic reactions are of increasing concern to practitioners in health-related fields. In modern orthodontic practice, adverse patient materials both an irritant and a allergic nature. Allergy patients undergoing treatment can be seen due several reasons these include nickel allergy, allergy the acrylic resins that used during treatment, latex products, etc. Safe effective practice depends on ...

BACKGROUND Surveillance on common allergens identified by patch testing plays an important role in emerging allergen detection, which leads to both individual and societal level prevention. OBJECTIVE To study the changes in the pattern of contact sensitization and to identify risk factors associated with allergens. METHOD The data of 206 patients who underwent patch testing at King Chulalon...

BACKGROUND AND OBJECTIVE Nickel is one of the most prevalent causes of contact allergy in the general population. This study focuses on human exposure to airborne nickel and its potential to induce allergic sensitization. MATERIALS AND METHODS The study group consisted of 309 children at school-starter age living in the West of Germany in the vicinity of two industrial sources and in a rural ...

Nickel is the twenty-second most abundant element and the seventh most abundant transitional metal. It is an ubiquitous trace element and it is mostly adopted to manufacture stainless steel used to produce food processing equipment and containers. The metal allergy is often caused from Ni and females are affected more commonly than males. When Ni allergy develop it tends to persist life-long. F...

OBJECTIVES To determine the prevalence of metal contact allergy among the children seen at a health center children with metal allergies in terms of risk factors. METHODS This was an uncontrolled cross-sectional study undertaken at a health center in Belo Horizonte, Brazil. Children aged from 0 to 12 years were recruited when they presented at the health center for routine pediatric consultat...

INTRODUCTION Contact with nickel-releasing coins as a cause of hand dermatitis has been debated. AIM Studying a hand dermatitis risk from handling Kuwaiti cupronickel coins among nickel-allergic and nickel non-allergic subjects. MATERIAL AND METHODS One hundred hand dermatitis patients (group I: nickel-allergic) and 100 matched patients (group II: nickel non-allergic) were selected from ove...

Metals, especially nickel, are the most common contact allergens in children. Recent data has shown increased incidence of allergy in industrialized countries. Sensitization can occur at any age, even in neonates. Costume jewelry, particularly earrings, is linked to increased sensitization to nickel. Sensitization to cobalt often occurs by the use of costume jewelry. The most common source of s...
