Contact dermatitis to hair dye: an update.

Exposure to hair dyes has long been known as a significant risk factor for development of allergic contact dermatitis among the exposed population as these lead to severe eczema of face and upper trunk in the consumer and hand eczema in hair-dressers. Currently, para-phenylenediamine (PPD) is the main ingredient used in permanent hair color products in the market and is the most important allergen. Prevalence of PPD sensitization is high in patients with contact dermatitis across all continents, with hair dye use being the commonest cause. In order to decrease the burden of disease, use of alt…

A case of irritant contact dermatitis with leech.

Medicinal leeches are invertebrated parasites that have been used for medical purposes for centuries as one of the traditional treatment methods. Medicinal leeches are used for wound and flap healing in the plastic and reconstructive surgery, in the treatment of venous insufficiency, varicosities, hemorrhoids, and in many other diseases. However, due to medicinal leech therapy (hirudotherapy) complications such as anaphylaxis, local allergic reactions, anemia, and mucosal synechiae can occur. In this article, we report a case of an irritant contact dermatitis in a patient who experienced sever…

Minor criteria for atopic dermatitis in children.

Atopic dermatitis (AD) is a common pruritic, eczematous skin disorder that runs a chronic and relapsing course. Major and minor criteria exist as guideline for arriving at a diagnosis of AD. Minor features vary with ethnicity and genetic background and can be used to aid diagnosis. A descriptive study was conducted including 210 patients of 1-12 years age who had concurrent or past history of AD according to criteria of Hanifin and Rajka. This study was conducted in the department of Dermatology of three different Hospitals of Bangladesh. Out of 33 sub-criteria of Hanifin and Rajka, 20 of whic…

The role of contact allergy in atopic dermatitis.

Although allergic contact dermatitis (CD) was previously thought to occur less frequently in patients with atopic dermatitis (AD), more recent studies show that it is at least as common in patients with AD as in the general population, if not more so. Thus, patients with AD should be considered for patch testing (PT). Although conflicting data exist, the severity of the AD may impact the PT results. Furthermore, younger patients may yield more positive PT results. Hand eczema and compositae allergy are more common in atopic patients. Reassuringly, PT is positive for topical antiseptic and cort…

Extrinsic and intrinsic types of atopic dermatitis.

Atopic dermatitis (AD) can be categorized into the extrinsic and intrinsic types. Extrinsic or allergic AD shows high total serum IgE levels and the presence of specific IgE for environmental and food allergens, whereas intrinsic or non-allergic AD exhibits normal total IgE values and the absence of specific IgE. While extrinsic AD is the classical type with high prevalence, the incidence of intrinsic AD is approximately 20% with female predominance. The clinical features of intrinsic AD include relative late onset, milder severity, and Dennie-Morgan folds, but no ichthyosis vulgris or palmar …

The role of food allergy in atopic dermatitis.

Atopic dermatitis (AD) affects ∼10% of children. Food allergy is a known provoking cause of AD in a subset of affected children. A literature search of PubMed and Medline was conducted to review the epidemiology and pathophysiology of AD, with special focus on the role of food allergy in the development of AD, its management, and its long-term preventive strategies. A literature search of PubMed and Medline was conducted. Food allergens readily provoke AD in ∼35% of patients, as proven through double-blind placebo-controlled food challenge studies. Milk, egg, wheat, soy, and peanut account for…

Contact dermatitis with a highlight on silver: a review.

Contact dermatitis is an inflammatory reaction in the skin that arises from exposure to an irritant or allergen. Irritant contact dermatitis is the most common form of dermatitis and occurs when any substance disrupts the epidermal skin barrier. All individuals are susceptible to this type of reaction. Allergic contact dermatitis is a delayed Type IV hypersensitivity reaction that occurs in individuals that have previously been sensitized to a particular antigen. Patients with wounds are at particular risk of developing either an allergic or irritant contact dermatitis. Various contribut…

DESIGN: Retrospective cohort study. SETTING: National Institutes of Health (NIH). PATIENTS: Patients seen at the NIH during the 1972-2010 period who had clinical findings consistent with DH, whose normal skin showed the presence of granular IgA deposits at the dermoepidermal junction on direct immunofluorescence (DIF) examination, whose age of disease onset was known, who had DH for at least 2 years, and who…

Geographical distribution of cercarial dermatitis in Norway.

Bird schistosomes can cause a disease called cercarial dermatitis, or swimmer's itch, in humans. The disease occurs when people have direct contact with fresh water or sea water containing the free-swimming cercariae of the flukes. The symptoms are well known, and include intense itching, maculae, papulae, urticariae and, in some cases, local oedema with enlarged lymph nodes and fever. In this study, we present the geographical distribution of freshwater cercarial dermatitis in Norway. The study is based on random reports obtained from both individuals and physicians treating patients with itc…
