The introduction of the euro has revived interest in the risk of nickel allergy due to the handling of coins. In the present work, the transfer of metallic contamination during the manipulation of coins is examined by means of leaching experiments and manipulation tests. It is shown that pre-existing metallic species present on the surface of the coins are the major source of contamination duri...
BACKGROUND Spectacle contact allergy is not infrequent. The fine scratches on the spectacle frames which may play a role in the sensitization to the potential allergenic components have not been studied. OBJECTIVE We sought the relationship between the scratches on the spectacle frames and the allergic contact dermatitis (ACD) in the Republic of Korea. METHODS A total of 42 Korean patients ...
Background and aim: The frequency of sensitization to contact allergens varies in different countries because of both genetic and, more importantly, allergen exposure variations. The objective is to determine the frequency of sensitization to contact allergens in Iranian patients with dermatitis.Materials and methods: Four hundreds and one patients with a clinical diagn...
There are very few reports on hypersensitivity reactions in association with titanium-based materials so that the existence of allergy to titanium is still put in question. We report on a patient in whom impaired fracture healing and eczema localized to the perioperative area developed upon titanium-based osteosynthesis. Patch testing gave no reactions to titanium nor to nickel, chromium, or co...
Henna tattoo contact dermatitis – a report of four cases and brief review of the selected literature
Temporary henna tattoos have recently become increasingly popular, especially among teenagers. Combining henna with other colouring agents such as para-phenylenediamine (PPD) may increase its potential for contact sensitization, cross-reaction to related compounds, as well as life-long allergy. Several cases of contact dermatitis from temporary tattoos with black henna have been reported in the...
BACKGROUND Burning mouth syndrome (BMS) is a burning or sore mouth in the absence of changes in the oral mucosa. It is often difficult to diagnose and treat. Numerous theories of the etiology have been suggested, including contact allergy. OBJECTIVE To determine the clinical utility of patch testing in patients with BMS. METHODS We retrospectively reviewed the charts of patients diagnosed w...
BACKGROUND The patch test is considered to be the gold standard for diagnosing nickel (Ni) allergy. The lymphocyte transformation test (LTT) can also be used to detect Ni sensitization. However, little is known about the correlation between patch test and LTT reactions to Ni. OBJECTIVE To establish and validate an LTT for Ni sensitization by comparison with patch test reaction and history. ...
