Chronic actinic dermatitis.

Abstract

Chronic actinic dermatitis (CAD) is one of the most frequently encountered photodermatoses in patients older than 50 years of age. It is characterized by persistent redness of the face and other exposed areas. CAD can become so severe that even nonexposed parts of the body develop eczematous lesions and the disease persists during winter. The diagnosis must be confirmed by phototests that show a broad action spectrum with low threshold doses. CAD must be differentiated from photocontact allergy and airborne dermatitis. The histopathologic features in the early stages are comparable to contact dermatitis, whereas in the later stages they may be those of pseudolymphoma. The most popular treatments are azathioprine and PUVA.

The long-term effect of multidisciplinary back training: a systematic review.

STUDY DESIGN: Systematic review of randomized controlled trials. OBJECTIVES: To determine the long-term effect of multidisciplinary back training on the work participation of patients with nonspecific chronic low back pain. SUMMARY OF BACKGROUND DATA: Chronic low back pain is influenced by multiple factors. Multidisciplinary back training represents one of the options to take this multiplicity into account. So far, only evidence of the short-term effectiveness of this approach in terms of work participation is available. METHODS: Electronic databases were searched and the references of various articles were screened for relevant publications. Ten studies met the inclusion criteria. All included studies were evaluated for their methodologic quality. RESULTS: Five of the studies had a low methodologic quality. All high-quality studies found a positive effect on at least one of the 4 outcome measures used. Based on our criteria, effectiveness was found for the outcome measures of work participation and quality of life. No effectiveness was found for experienced pain and functional status. The intensity of the intervention seems to have no substantial influence on the effectiveness of the intervention. CONCLUSION: In the long-term, multidisciplinary back training has a positive effect on work participation in patients with nonspecific chronic low back pain.
