Randomized Controlled TrialSafety and efficacy of Curcuma longa extract in the treatment of painful knee osteoarthritis: a randomized placebo-controlled trial.
Curcuma longa Linn. is widely used for the treatment of disorders associated with inflammation and was evaluated for its safety and efficacy in the treatment of painful knee osteoarthritis (OA). This was a randomized, single blind, placebo-controlled trial. Total of 120 patients (37 males and 83 females) with primary knee OA received either placebo (400 mg twice daily) or NR-INF-02 (500 mg twice daily) or glucosamine sulphate (GS) (750 mg twice daily) alone or combination of NR-INF-02 and GS for 42 days. ⋯ NR-INF-02 treated group showed a significant (p < 0.01) decrease in use of rescue medication, along with clinical and subjective improvement compared to placebo. The tolerability and acceptability profile of NR-INF-02 was better during the trial period. The study demonstrates safety and efficacy of NR-INF-02 as a useful treatment option for patients with primary painful knee OA.

Possible mechanism of protective effect of thalidomide in STZ-induced-neuropathic pain behavior in rats.
Diabetes-induced neuropathic pain is recognized as one of the most difficult type of pain to treat and conventional analgesics are well known to be partially effective or associated with potential toxicity. Recently, it has been demonstrated that thalidomide, besides its teratogenic potential, reduced chronic pain in an SNL experimental pain model. ⋯ It may be concluded that thalidomide has a beneficial effect in neuropathic pain by decreasing cytokines (TNF-α) and nitric oxide level and may provide a novel promising therapeutic approach for managing painful diabetic neuropathy.

In their systematic review, Zhang et al. evaluate randomized controlled trials on the efficacy of Botulinum toxin type A (BoNTA) in helping patients with musculoskeletal disorders. Scoring each trial according to the Jadad scale they note that the studies range from 1 to 5 with an average of 4.1, which they interpret as a testimony of the high quality of the studies included. Unfortunately, we cannot share the author's enthusiasm, as a perfect Jadad score of 5 is no guarantee that a study is of good quality.

Anti-inflammatory and analgesic activity of protocatechuic acid in rats and mice.
Anti-inflammatory and analgesic activity of protocatechuic acid (PCA), a natural product, was evaluated in different rat models (viz., carrageenan-induced paw oedema, cotton pellet-induced granuloma and Freund's adjuvant arthritis) of inflammation and chemical and heat induced mouse models of pain. Treatment with PCA inhibited significantly different biological parameters like hind paw oedema, granuloma exudates formation and arthritis index in carrageenan oedema, cotton pellet granuloma and Freund's adjuvant arthritis, respectively. The biochemical changes viz., glutathione, superoxide dismutase, catalase, lipid peroxidation and NO in oedematous or in liver tissues and serum alanine aminotransferase and lactic dehydrogenase occurred during different types of inflammation were either significantly restored or inhibited with PCA pretreatment. Present experimental findings demonstrate promising anti-inflammatory and analgesic activity of PCA which is comparable with that of standard drugs used.
