Topical diclofenac is widely used in the treatment of pain and inflammation. This comprehensive review assesses the safety and efficacy of topical diclofenac in a range of painful and inflammatory disorders. ⋯ This evidence-based review shows topical diclofenac to be an effective and well tolerated treatment in painful and inflammatory conditions, at least in the short-term. However, only published RCT studies have been included in this analysis, which may exclude some interesting data from non-RCT studies. Future trials of topical diclofenac need to be of longer duration, be better reported and consider a broader spectrum of acute and chronic pain indications.

The estimated prevalence of dietary-supplement use among US adults was 73% in 2002. Appropriate use of dietary supplements within the paradigm of evidence-based medicine may be a challenge for medical doctors and non-physician clinicians. Randomized, controlled, clinical trial data, which are considered the gold standard for evidence-based decision making, are lacking. Standardized guidelines for the use of dietary supplements are lacking, and dietary supplements can bear unsupported claims. ⋯ The use of dietary supplements may be associated with adverse events. Although there are new regulatory requirements for dietary supplements, these products will not require FDA approval or submission of efficacy and safety data prior to marketing under the new regulation. A limitation to the literature used for this review is the lack of prospective, randomized clinical trials on the safety and efficacy of dietary supplements. Clinicians should be aware of all the dietary supplements that their patients consume, and help their patients make informed decisions appropriate to their medical care.

Review
A review of Paget's disease of bone with a focus on the efficacy and safety of zoledronic acid 5 mg.
Paget's disease of bone, the second most common metabolic bone disease in the United States, is characterized by localized areas of excessive bone resorption coupled with accelerated bone formation, resulting in new bone that is less structurally organized and is weaker than normal bone. Complications of Paget's disease can include bone pain, osteoarthritis, skeletal deformity, hearing loss, and fractures. The objective of this review is to provide a comprehensive overview of current standards of treatment in Paget's disease. ⋯ The etiology of Paget's disease is unclear, but some evidence suggests genetic and viral components. Bisphosphonates restore normal bone turnover and relieve bone pain, but oral formulations may be limited by complicated dosing regimens and poor gastrointestinal absorption. The bisphosphonate, zoledronic acid is administered as a single intravenous infusion and offers antiresorptive efficacy and longer-lasting remission.

Review Case Reports
A practical overview of tizanidine use for spasticity secondary to multiple sclerosis, stroke, and spinal cord injury.
Tizanidine is an imidazoline central alpha(2)-adrenoceptor agonist widely used to manage spasticity secondary to conditions such as multiple sclerosis (MS), stroke, and spinal cord injury (SCI). While there is widespread use of tizanidine in clinical practice, little practical information is available to assist prescribers with the effective use of tizanidine for spasticity management. The aim of this review is to provide an up-to-date overview of tizanidine and its use in the management of spasticity associated with acquired (SCI), static (stroke), and progressive neurological (MS) diseases. ⋯ There is a large body of evidence for the effective use of tizanidine monotherapy in the management of spasticity. A case study demonstrates that combination therapy can effectively control spasticity while better managing dose-dependent adverse events, although additional studies need to be performed to confirm these results.

To review data on the prevalence of vitamin D inadequacy and its causes in postmenopausal women in Eastern Asia. ⋯ Non-uniform, epidemiological studies indicate a high prevalence of vitamin D inadequacy in postmenopausal women in Eastern Asia. Recommended remedial approaches are education campaigns and broad-based provision of vitamin D supplementation.
