Marginal zone lymphoma.

Abstract

Marginal zone lymphomas (MZLs) comprise 3 distinct entities: extranodal MZL of mucosa-associated lymphoid tissue (MALT), splenic MZL, and nodal MZL. Gastric MALT lymphoma is the most common extranodal MZL and often develops as a result of chronic Helicobacter pylori gastritis. Such cases frequently respond to antibiotics directed against H. pylori. Antigen-driven lymphomatous disease can also be seen in the association of Borrelia burgdorferi with MALT lymphoma of the skin, Chlamydia psittaci with MALT lymphoma of the ocular adnexa, Campylobacter jejuni with immunoproliferative disease of the small intestine, and hepatitis C with splenic MZL. This article discusses the pathogenesis and clinical features of MZL and the treatment options available to patients.

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.
