ECG changes associated with spontaneous left-sided pneumothorax.

Abstract

A patient with chronic obstructive pulmonary disease had a 100% pneumothorax on the left side associated with marked ECG changes. The changes occurring in this situation can be confusing. Because of the high prevalence of coronary heart disease in patients presenting with left-sided chest pain, an ECG usually is obtained to rule out acute myocardial infarction, in many instances even before history taking, physical examination, or chest x-ray study is done. Therefore, familiarity with the ECG manifestations of left-sided penumothorax is necessary to avoid delay in establishing the diagnosis and in beginning therapy.

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.
