Pain is the most prominent symptom and clinical finding in osteoarthritis (OA). Acetaminophen and nonsteroidal anti-inflammatory drug (NSAID) therapy are the mainstays of OA analgesia, but other drug and non-drug therapy, joint injections, and surgery may be needed to provide reasonable quality of life. Regularly scheduled, low-dose opioids can produce good relief of chronic nonmalignant pain including pain caused by OA. This paper reviews the potential risks and benefits of opioids, the evidence supporting their use in OA pain, and guidelines for their use in OA pain.

Apoptosis of skeletal muscle cells and the pathogenesis of myositis: a perspective.
Apoptosis is a genetically controlled form of cell death that occurs in many biologic processes including embryogenesis, immune cell development, and maintenance of peripheral immune tolerance. Recent studies have yielded evidence suggesting that apoptosis of parenchymal cells may play a role in providing self-antigens to initiate autoimmune reactions. Skeletal muscle cells are fully differentiated and multinucleated. ⋯ However, the involvement of apoptosis in skeletal muscle pathologies is unclear. This article reviews the available data concerning the occurrence of skeletal muscle cell apoptosis in selected muscle diseases. It also discusses the potential role of muscle cell apoptosis in the development of autoimmune diseases such as idiopathic inflammatory myopathies.

Fibromyalgia is a puzzling syndrome of widespread musculoskeletal pain. In addition to pain, patients with fibromyalgia frequently report that cognitive function, memory, and mental alertness have declined. ⋯ These questions concern the types of cognitive tasks that are problematic for patients with fibromyalgia, the role of psychological factors such as depression and anxiety, the role of physical factors such as pain and fatigue, the nature of patients' perceptions of their cognitive abilities, and whether patients can be tested for cognitive dysfunction. Critical areas for further investigation are highlighted.

Fibromyalgia (FM) is a syndrome of chronic widespread musculoskeletal pain that is accompanied by sleep disturbance and fatigue. Clinical treatment usually includes lifestyle modifications and pharmacologic interventions meant to relieve pain, improve sleep quality, and treat mood disorders. These therapies are often ineffective or have been shown in clinical studies to have only short-term effectiveness. ⋯ Most studies on these treatments have been performed for osteoarthritis, rheumatoid arthritis, or focal musculoskeletal conditions. Clinical trials are scarce; the quality of these trials is often criticized because of small study population size, lack of appropriate control interventions, poor compliance, or short duration of follow-up. However, because of widespread and growing use of alternative medicine, especially by persons with chronic illnesses, it is essential to review efficacy and adverse effects of complementary and alternative therapies.
