Osteoarthritis is the most common form of arthritis, its prevalence increasing with age: as much as 80% of the population over 75 years show radiologic signs of the condition. Symptoms include pain, stiffness, and functional impairment; however, not all patients are symptomatic. Management starts with nonpharmacologic interventions, followed by pharmacologic means, and ultimately by surgical intervention. ⋯ They make use of educational occupational, and physical advisers, and they use their medication on demand. The basis of this self-administered pharmacologic management is paracetamol-acetaminophen, sometimes in combination with NSAIDs. A promising option for the future is the development of symptomatic slow-acting drugs for osteoarthritis that possess structure-modifying properties.

Randomized Controlled Trial Comparative Study Clinical Trial
Valdecoxib is more efficacious than rofecoxib in relieving pain associated with oral surgery.
Inhibition of the cyclooxygenase (COX)-2 enzyme has been shown previously to reduce pain and inflammation. Valdecoxib is a new highly selective COX-2 inhibitor with a rapid onset of action and significant analgesic properties. This study compared the analgesic efficacy of valdecoxib and rofecoxib in treating postoperative pain in patients undergoing oral surgery. ⋯ Valdecoxib also demonstrated efficacy that was superior to that of rofecoxib with respect to the percentage of patients requiring rescue medication or experiencing regimen failure (p < or =.05). Valdecoxib, rofecoxib, and placebo were equally well tolerated. This study demonstrates that valdecoxib provides significantly greater analgesic efficacy than rofecoxib in the management of pain after oral surgery.

Upper respiratory tract febrile illnesses caused by various viruses, mycoplasma, chlamydia infections, and/or inflammatory diseases are usually observed a few days to a few (several) weeks before the onset of Reye's syndrome, Stevens-Johnson syndrome, autoimmune hepatitis (hepatotropic virus infections), or hepatotoxicity associated with therapeutic administration of acetaminophen in persons with varying degrees of deficits of important enzymatic activity. Activation of systemic host defense mechanisms by inflammatory component(s) results in depression of various induced and constitutive isoforms of cytochrome P-450 mixed-function oxidase system superfamily enzymes in the liver and most other tissues of the body. ⋯ On the other hand, it must be emphasized that inhibition of metabolism of several drugs, as well as influence on the concentration and/or ratio of various cytokines in inflamed tissues, may exert beneficial effects in patients with different diseases, thus opening new therapeutic possibilities. Clinically relevant interactions may be exemplified by the effects of some fluoroquinolone antibiotics, such as pefloxacin and ciprofloxacin, which probably have a steroid-sparing effect in some patients with frequently relapsing nephrotic syndrome, and an increased bioavailability of several drugs following concomitant intake with freshly pressed grapefruit juice, eventually caused by inhibition of their metabolism, mediated mainly by CYP3A and specifically inhibited by naturally occurring flavonoids.

Randomized Controlled Trial Multicenter Study Clinical Trial
Valdecoxib, a COX-2-specific inhibitor, is an efficacious, opioid-sparing analgesic in patients undergoing hip arthroplasty.
Opioid agents are highly effective analgesics after orthopedic surgery but are associated with several adverse effects. Valdecoxib is a new, highly selective cyclooxygenase (COX)-2-specific inhibitor with a rapid onset of action and significant analgesic properties that is being developed for the management of acute pain. The objective of this study was to demonstrate the opioid-sparing efficacy of valdecoxib as part of a multimodal treatment of pain associated with hip arthroplasty. ⋯ Valdecoxib and placebo were equally well tolerated. Pre- and postoperative administration of valdecoxib reduces the amount of morphine required for postoperative pain relief and provides greater analgesic efficacy compared with morphine alone. Thus, valdecoxib has significant clinical utility for acute pain management in orthopedic surgery patients.

The objective of this article is to provide a concise overview of the most likely biological and chemical agents that could be used as biochemical weapons. The diagnosis, pathology, prevention, decontamination, treatment, and disposition of these biological and chemical agents are presented in a tabular format for quick reference purposes. The information provided outlines the bare essentials needed to deal with any emergency or catastrophic event involving these agents.
