BACKGROUND A chronic dermatosis like nummular dermatitis may be complicated by contact dermatitis due to an impaired cutaneous barrier. This study is aimed at evaluating secondary contact dermatitis in patients with nummular dermatitis. METHODS Patch testing with the Indian Standard Series was performed in 50 of 78 patients with a clinical diagnosis of nummular eczema. Significant reactions w...

Contact dermatitis is an inflammatory skin condition induced by exposure to an environmental agent. Eczema and dermatitis are used synonymously to denote a polymorphous pattern of skin inflammation characterized at least in its acute phase by erythema, vesiculation and pruritus. Substances responsible for contact dermatitis after single or multiple exposures are non protein chemicals, i.e. hapt...

Sir, Allergic contact dermatitis is the most common cause of peri-orbital eczema (1). It may be caused by allergens brought in contact with the eyelids by hand transfer (like toluene sulfonamide-formaldehyde resin in nail polishes), by airborne contact (like sesquiterpene lactones) or, most frequently, by direct application of cosmetics or topical ophthalmic medicaments. The percentage of sensi...

Contact dermatitis or eczema is a polymorphic inflammation of the skin. It occurs at the site of contact with irritating or antigenic substances. In the acute phase there is occurrence of itching erythema, papules, and vesicles, whereas in the chronic phase there is dryness, hyperkeratosis, and sometimes fissures. Contact dermatitis can be divided into irritant and allergic types. Allergic cont...

many patients with atopic eczema (ae) would “march” to develop allergic rhinitis (ar) and asthma. physicians, patients and their families often do not appreciate the significance of these diseases as co-morbidities of atopy. the aim of this study was to evaluate the prevalence and severity of airway atopies in patients with ae. ar and asthma severity were assessed in consecutive ae patients see...

Background Allergic contact dermatitis (ACD) is often under-recognized in the pediatric population. In the first years of life ACD it is often confused with other types of dermatitis, such as irritant dermatitis or atopic eczema (AE). In the last two decades an increase in ACD in children and adolescents was observed, reaching similar frequencies to those seen in adults (20-70%). ACD acquired i...

BACKGROUND Linalool is a commonly used fragrance terpene that forms potent sensitizers upon oxidation. In a recent multicentre study, we found that 7% of 2900 patients showed positive patch test reactions to oxidized linalool at 6.0%. No elicitation studies have been performed. OBJECTIVE To identify threshold concentrations for elicitation of allergic contact dermatitis caused by oxidized lin...

BACKGROUND Atopic dermatitis (AD) is a chronically relapsing dermatitis with no known cure. Due to the chronic nature of the condition, frequent and long term topical therapy is used. This may lead to sensitization, resulting in allergic contact dermatitis (ACD). AIMS The aim of the study was to observe the frequency of ACD in atopic patients in this part of the country using Indian standard ...

a positive association between acetaminophen intake and allergic diseases has recently been reported in developed countries with impaired oxidant/antioxidant balance and promotion of atopy as proposed underlying mechanisms. the aim of the study was to explore the relationship between acetaminophen intake and asthma, hay fever, and eczema in the republic of macedonia as a country with acetaminop...
