Treatment of Degenerative Lumbar Spinal Stenosis - Article

ABSTRACT: Spinal stenosis is a narrowing of the vertebral canal that compresses spinal nerves and may cause leg pain and difficulty walking. The symptoms of degenerative lumbar stenosis commonly occur in elderly adults and can be treated conservatively with pain-relieving agents or aggressively with decompressive surgery. Most studies of the effectiveness of treatments are poor in quality; however, there appear to be potential relationships between treatments, patient characteristics, and treatment outcomes. Studies indicate the following: (1) local anesthetic block can reduce symptoms on a short-term basis, while epidural steroids offer no additional benefit; (2) patients with moderate or severe symptoms benefit more from surgery than from conservative therapy; and (3) patients with leg pain and severely restricted walking ability regain mobility after surgery. Definitive evidence-based conclusions about the efficacy of conservative or surgical treatments await the results of well-designed clinical trials.

Pulmonary Rehabilitation in the Treatment of Chronic Obstructive Pulmonary Disease - Article

ABSTRACT: Pulmonary rehabilitation is a nonpharmacologic therapy that has emerged as a standard of care for patients with chronic obstructive pulmonary disease. It is a comprehensive, multidisciplinary, patient-centered intervention that includes patient assessment, exercise training, self-management education, and psychosocial support. In the United States, pulmonary rehabilitation is usually given in outpatient, hospital-based programs lasting six to 12 weeks. Positive outcomes from pulmonary rehabilitation include increased exercise tolerance, reduced dyspnea and anxiety, increased self-efficacy, and improvement in health-related quality of life. Hospital admissions after exacerbations of chronic obstructive pulmonary disease are also reduced with this intervention. The positive outcomes associated with pulmonary rehabilitation are realized without demonstrable improvements in lung function. This paradox is explained by the fact that pulmonary rehabilitation identifies and treats the systemic effects of the disease. This intervention should be considered in patients who remain symptomatic or have decreased functional status despite optimal medical management. Medicare now covers up to 36 sessions of pulmonary rehabilitation in patients with moderate, severe, and very severe chronic obstructive pulmonary disease.
