Current pain and headache reports

Fibromyalgia is a frequent cause of chronic widespread pain and affects up to 5% of the general population. Diagnosis and treatment have been especially challenging due to limited knowledge of etiology and poor response to conventional treatment of pain. Appreciation for the interactions of neurobiologic, psychologic, and behavioral factors in the disease pathogenesis has led to improved treatment options that can be effective in individual patients. Current evidence advocates a multifaceted program emphasizing patient education, medications for improving symptoms, and aggressive use of exercise and cognitive-behavioral approaches to retain or restore function.

ReviewAn update on nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 inhibitors.
Selective inhibitors of the cyclooxygenase-2 enzyme were developed to treat pain and inflammation while reducing the risk of the serious gastrointestinal side effects seen with nonselective nonsteroidal anti-inflammatory drugs (NSAIDs). The results of several clinical trials have demonstrated an apparent increased risk of serious cardiovascular events in patients taking the COX-2-selective inhibitors. ⋯ An increase in cardiovascular risk actually has been seen with anti-inflammatory drugs of the NSAID class, regardless of whether they are selective or nonselective inhibitors. The US Food and Drug Administration has recommended that all such drugs carry a black box warning for gastrointestinal and cardiovascular risks.

Tension-type headache (TTH) is a very common problem that usually causes only minimal to moderate discomfort and little disability. If episodic TTH evolves to chronic TTH, then the morbidity in terms of discomfort, disability, and use of medication escalates dramatically. ⋯ There is a modest increase in prevalence between the ages of 30 and 50 years and a decrease to 25% to 35% prevalence after the age of 60 years. TTH appears to remain a problem for most sufferers throughout their lives.

Medication-overuse headache (MOH) can be caused by almost all anti-headache drugs including analgesics, ergots, triptans, and combined preparations The prevalence of chronic daily headache (CDH) appears to be between 2% and 4% in the general population. Current epidemiologic studies suggest that MOH accounts for approximately 50% of these cases. ⋯ Prednisone decreases the duration of headache in the first days of withdrawal therapy. The only strategy to reduce the prevalence of MOH is to prevent the development of MOH in the first place by restriction of anti-headache drugs and constant education of patients.

ReviewThe use of opioids in the treatment of osteoarthritis: when, why, and how?
As life expectancy increases every decade, the incidence and prevalence of osteoarthritis (OA) also will increase. Despite progress in our knowledge of the pathophysiology of OA, the management of OA-mediated pain continues to challenge physicians. Concern regarding the cardiovascular effects of cyclooxygenase-2 inhibitors and the gastrointestinal and renal side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) in general has limited the use of these medications in the management of chronic non-cancer pain. ⋯ When used as part of a multimodal approach to pain control, opioids are a safe and effective treatment for joint pain, including that of OA. Patients for whom NSAIDs are contraindicated, or for whom combined acetaminophen, tramadol, and NSAID therapy is ineffective, may be started on low-dose opioids and titrated as needed and tolerated. Patient education and informed consent, exercise, complementary medicine, and the use of a controlled substance agreement increases the likelihood of patient compliance with treatment guidelines, improving functional capacity and quality of life.
