US3 Allergy in dental practice

ORAL DISEASES, Issue 2006

Allergy reactions of the oral mucosa comprise an array of clinical manifestations, some of them difficult to differentiate from toxic reactions. Type-I reactions are most frequently seen related to application of polymers in the oral cavity, such as orthodontic bonding and fissure sealant materials. There may also be systemic manifestations such as urticaria. Type-IV reactions may be seen related to most dental materials used, from amalgam and gold to polymers. These reactions appear as chronic reddening and/or ulceration of the oral mucosa. Lichenoid reactions have histopathological characteristics compatible with type-IV allergy reactions and are the most prevalent material-adverse reactions seen in the oral cavity. Recent advances have been made in characterizing the more prevalent allergens on oral mucosa, such as methacrylates, natural rubber latex (NRL) proteins, rubber glove chemicals and disinfectants. This improved understanding has clearly enhanced the success, particularly for type I NRL allergies. Skin patch tests, applying a series of dental materials in non-toxic concentrations on the skin, have been used to identify sensitization. However, the value of those tests can be questioned. Although obvious advances have been made in characterizing dental allergens and understanding potential exposure, improved diagnostic and management techniques are still needed. Corticosteroid therapy is all too often the only treatment. Drug allergy including local anaesthetics, and systemic antibiotics and NSAIDs, may also present in the dental environment, causing life-threatening emergencies specially in 'at risk patients'. The GDP has to know the principles of prevention, diagnosis and management of these situations. [source]

Cutaneous allergic reactions to tattoo ink

JOURNAL OF COSMETIC DERMATOLOGY, Issue 4 2009
Ravneet Ruby Kaur BSN
Summary Tattoo artists use many compounds to create tattoo pigment and several allergic reactions can occur as a result of these additives. The compositions of many inks have been identified; however, as new mixtures are created it becomes difficult to identify the specific ingredients in a particular ink. Allergic reactions to a particular pigment can manifest in several ways including allergic contact dermatitis and photoallergic dermatitis. Subsequently, tattoo ink or pigment allergy reactions can be classified as acute inflammatory reactions, allergic hypersensitivities, and granulomatous, lichenoid, and pseudolymphomatous types of reactions. This paper will review the clinical manifestations and the most common compounds associated with cutaneous reactions to tattoo ink. [source]

The management of the allergic child at school: EAACI/GA2LEN Task Force on the allergic child at school

The management of the allergic child at school: EAACI/GA2LEN Task Force on the allergic child at school. Allergy 2010; 65: 681,689. Abstract Allergy affects at least one-quarter of European schoolchildren, it reduces quality of life and may impair school performance; there is a risk of severe reactions and, in rare cases, death. Allergy is a multi-system disorder, and children often have several co-existing diseases, i.e. allergic rhinitis, asthma, eczema and food allergy. Severe food allergy reactions may occur for the first time at school, and overall 20% of food allergy reactions occur in schools. Up to two-thirds of schools have at least one child at risk of anaphylaxis but many are poorly prepared. A cooperative partnership between doctors, community and school nurses, school staff, parents and the child is necessary to ensure allergic children are protected. Schools and doctors should adopt a comprehensive approach to allergy training, ensuring that all staff can prevent, recognize and initiate treatment of allergic reactions. [source]
