Randomized Controlled Trial Multicenter Study Comparative StudyLumiracoxib is effective in the treatment of osteoarthritis of the knee: a prospective randomized 13-week study versus placebo and celecoxib.
The objective of this study was to evaluate the efficacy, safety and tolerability of lumiracoxib compared with placebo and celecoxib in patients with osteoarthritis (OA). Following a 3- to 7-day washout period for previous non-steroidal anti-inflammatory drugs, 1,600 patients aged >or=18 years with primary knee OA were randomized to receive lumiracoxib 200 or 400 mg once daily (o.d.), celecoxib 200 mg o.d. or placebo for 13 weeks. Primary efficacy variables were OA pain intensity in the target knee, patient's global assessment of disease activity and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale and total scores at week 13. ⋯ The incidence of adverse events was similar across the groups. Lumiracoxib 200 mg o.d. is a well-tolerated and effective treatment option for OA of the knee, providing pain relief and improved functional status with efficacy superior to placebo and similar to celecoxib. Lumiracoxib demonstrated a tolerability profile similar to placebo and celecoxib.

Case ReportsRemitting seronegative symmetrical synovitis with pitting edema in leprosy.
A 67-year-old man, who had widespread and well-defined erythematous violaceous hyperkeratotic plaques on his skin, was diagnosed with borderline tuberculoid leprosy. The patient began treatment with clofazimine, rifampicin, and dapsone, but 15 days afterwards he complained of acral edema with godet sign. Magnetic resonance imaging was done, and the case was interpreted as remitting seronegative symmetrical synovitis with pitting edema. About 8 mg/day of methylprednisolone were started with excellent response.

Randomized Controlled Trial Comparative StudyComparison of intra-articular tenoxicam and oral tenoxicam for pain and physical functioning in osteoarthritis of the knee.
This study was designed to compare efficacy of local administration of a nonsteroidal anti-inflammatory drug with systemic administration in patients with osteoarthritis (OA) of the knee. For this purpose, intra-articular tenoxicam and oral tenoxicam therapies were applied and the improvement in control of pain and physical functioning were evaluated. A total of 69 patients with OA of the knee were randomized into three groups. ⋯ There was no significant difference between the oral and intra-articular tenoxicam treatment regimens. The results of this study showed that treatment of OA of the knee with intra-articular tenoxicam is as effective as that with oral tenoxicam. It can be thought that intra-articular administration can be preferred to oral therapy due to minimal possibility of systemic side effects.

ReviewUpdate on guidelines for the treatment of chronic musculoskeletal pain.
Chronic musculoskeletal pain is a major - and growing - burden on today's ageing populations. Professional organisations including the American College of Rheumatology (ACR), American Pain Society (APS) and European League Against Rheumatism (EULAR) have published treatment guidelines within the past 5 years to assist clinicians achieve effective pain management. Safety is a core concern in all these guidelines, especially for chronic conditions such as osteoarthritis that require long-term treatment. ⋯ There are as yet no updated official guidelines that incorporate these new data and regulatory advice. An international multidisciplinary panel, the Working Group on Pain Management, has generated new recommendations for the treatment of moderate-to-severe musculoskeletal pain. These guidelines, formulated in response to recent developments concerning COX-2 inhibitors and other NSAIDs, focus on paracetamol as the baseline drug for chronic pain management; when greater analgesia is desired, the addition of weak opioids is recommended based on a preferable GI and cardiovascular profile, compared with non-steroidal anti-inflammatory drugs.

Persistent pain represents a major quality-of-life burden for patients and a challenge for their physician. Chronic pain often arises from multiple tissue sources and involves multiple chemical mediators and pain transmission pathways. Successful long-term pain management requires analgesic regimens that can treat pains of multiple origin and type. ⋯ Rational combinations of analgesic drugs offer a viable approach to managing persistent pain that involves multiple sites or pathways. The combination of paracetamol plus tramadol brings together two well-known analgesics that have different but complementary mechanisms of analgesic action. Laboratory studies have demonstrated that these agents interact to produce synergistic analgesia with a desirable safety/efficacy profile.
