INTRODUCTION Clinical studies indicate that contact allergy to glucocorticosteroids (GCS) is not rare and has been increasingly reported over the past decade. Among the risk factors for developing contact hypersensitivity to topical corticosteroids, chronic inflammatory skin diseases and polyvalent contact allergy seem to be most important. AIM To present the structure of contact allergy in t...

Possible relations between prevalence of sick building syndrome (SBS) and environmental, occupational, and personal factors were studied in a random sample (0.1%) of the general population aged 20-65 in a three county region in middle Sweden. Childhood exposure to environmental tobacco smoke from smoking mothers and a childhood in urban areas was related to SBS symptoms. Current urban residency...

Approximately 10% of the population in the USA suffer from nickel allergy, and many are unable to wear jewellery or handle coins and other objects that contain nickel. Many agents have been developed to reduce the penetration of nickel through skin, but few formulations are safe and effective. Here, we show that applying a thin layer of glycerine emollient containing nanoparticles of either cal...

Ancylostomum caninum larvae cause damage to the host at the point of entry through the skin leaving a wound vulnerable to secondary infections. As the larvae migrate through the skin an inflammatory response, dermatitis, is often stimulated which can be exacerbated in hosts which give hypersensitive responses. We assessed a 44-year-old man with contact dermatitis diagnosed as nickel allergy but...

Prof. Carlo Crosti, Clinica Dermatologica, Ospedale San Paolo, Via A Di Rudini, 8, I-20142 Milano (Italy) Despite its frequency, pompholyx or dyshidrotic eczema presents many unresolved problems of aetiology, pathogenesis and therapy. As its invariable histopatholog-ical picture of spongiotic dermatitis indicates, pompholyx is a non-specific reaction somehow related to the particular anatomy of...

UNLABELLED Nickel is a very common metal contained in many everyday objects and is the leading cause of ACD (Allergic Contact Dermatitis). Nickel is present in most of the constituents of a normal diet, but some food groups are usually considered to be richer. However, the nickel content of specific food can vary widely, depending on many factors. Thus, the daily intake of nickel is also highly...

BACKGROUND Fixed orthodontic appliances with the use of stainless steel brackets and archwires made of nitinol have a corrosive potential in the oral environment. Nickel and chromium ions released from these appliances act as allergens apart from being cytotoxic, mutagenic and carcinogenic in smaller quantities in the range of nanograms. This study was done to evaluate the release of nickel and...
