ETFAD/EADV eczema task force 2009 position paper on diagnosis and treatment of atopic dermatitis

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2010

Abstract Background, The diagnosis of atopic dermatitis (AD) is made using evaluated clinical criteria. Management of AD must consider the symptomatic variability of the disease. Methods, EADV eczema task force developed its guideline for atopic dermatitis diagnosis and treatment based on literature review and repeated consenting group discussions. Results and Discussion, Basic therapy relies on hydrating topical treatment and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin antagonists is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the topical calcineurin inhibitors, tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial/antiseptic treatment. Systemic antihistamines (H1) can relieve pruritus, but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. ,Eczema school' educational programmes have been proven to be helpful. [source]

Lichenoid photodermatitis associated with nimesulide

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2001
Umit Tursen MD
An 81-year-old-female patient presented with a 2 week history of erythematous to violaceous lichenoid papules and plaques exhibiting a reticulated pattern on the ,,V'' area of the chest and dorsal hands. Fine, whitish reticulated networks were present over the surface of many well developed papules. The lesions were sharply demarcated and moderately pruritic (Fig. 1). Figure 1. ,Violaceous lichenoid papules with reticular pattern located on the ,,V'' area of the chest The result of routine complete blood cell count, urinalysis, erythrocyte sedimentation rate, liver and kidney function tests were within normal limits. Antinuclear and anti-DNA antibodies were negative, and total C3 and C4 complement levels were normal. Hepatitis B surface antigen, anti-Hepatitis B surface antigen, anti-Hepatitis B core IgM antibody were negative, while anti-Hepatitis C virus antibody was positive. A skin biopsy specimen obtained from the neck of our patient revealed an interface lichenoid dermatitis accompanied by individual necrotic epidermal keratinocytes, parakeratosis and eosinophils in the infiltrate (Fig. 2).

The eruption resolved within 5 days. The rash returned following nimesulide rechallenge. [source]

Position paper on diagnosis and treatment of atopic dermatitis

ABSTRACT The diagnosis of atopic dermatitis (AD) is made using evaluated clinical criteria. Management of AD must consider the symptomatic variability of the disease. It is based on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment is used for exacerbation management. Topical corticosteroids remain the first choice. Systemic anti-inflammatory treatment should be kept to a minimum, but may be necessary in rare refractory cases. The new topical calcineurin inhibitors (tacrolimus and pimecrolimus) expand the available choices of topical anti-inflammatory treatment. Microbial colonization and superinfection (e.g. with Staphylococcus aureus, Malassezia furfur) can have a role in disease exacerbation and can justify the use of antimicrobials in addition to the anti-inflammatory treatment. Evidence for the efficacy of systemic antihistamines in relieving pruritus is still insufficient, but some patients seem to benefit. Adjuvant therapy includes ultraviolet (UV) irradiation preferably of UVA wavelength; UVB 311 nm has also been used successfully. Dietary recommendations should be specific and only given in diagnosed individual food allergy. Stress-induced exacerbations may make psychosomatic counselling recommendable. ,Eczema school' educational programmes have proved to be helpful. [source]

Narrow-band ultraviolet B phototherapy in patients with recalcitrant nodular prurigo

ABSTRACT Management of nodular prurigo has been less than satisfactory. Conventional therapies such as systemic antihistamines and topical steroids have not been particularly successful. The effects of narrow-band ultraviolet B (NB-UVB) phototherapy in the treatment of various inflammatory dermatoses have been proven, however, no data exist on the efficacy and the duration of remission in NB-UVB monotherapy for nodular prurigo. The aim of this study was to evaluate the effect of NB-UVB phototherapy on recalcitrant nodular prurigo. NB-UVB phototherapy was performed once a week on 10 patients with recalcitrant nodular prurigo. The initial dose was 0.4 J/cm2, and the dose was increased by 0.1 J/cm2 for each treatment. The treatment was performed until the eruption was almost clear. In each patient, a mean cumulative dose of 23.88 J/cm2 was applied over a mean of 24.3 irradiations. The mean maximum daily dose of ultraviolet B was 1.2 ± 0.4 J/cm2. NB-UVB phototherapy notably improved the eruption of nodular prurigo in all patients. Follow up at 1 year revealed that only one patient had relapsed. The remaining nine patients continued to derive long-term benefits. NB-UVB phototherapy appears to be an effective treatment for recalcitrant nodular prurigo, offering long-term benefits in the majority of those treated. [source]
