The current article reviews the cognitive-behavioral (CB) and operant-behavioral perspectives on chronic pain and suggests an answer to the question why changes in behaviors, attitudes, and emotions are associated with decreases in pain severity and impact discussing potential psychobiological mechanisms that may underlie cognitive and behavioral techniques. The impact of learning such as classical and operant conditioning in behaviors and physical responses including baroreflex sensitivity (BRS), as well as the influence of cognitions on pain perception and impact will be presented to explain general efficacy of cognitive-behavior therapy (CBT) and operant-behavioral therapy (OBT) in the treatment of people with fibromyalgia (FM) describing some of the limitations of published outcome studies. ⋯ We provide recommendations of how to move forward in approaching studies of CBT and OBT efficacy as a function of better understanding of patient characteristics and contextual factors. We advocate for the potential of the CB perspective and principle of learning for all health care providers regardless of discipline or training and will give examples for making more effective the patient-rheumatologist-relationship by using the principles discussed.

Systemic autoinflammatory diseases are a group of inherited disorders of the innate immunity characterized by the recurrence of febrile attacks lasting from few hours to few weeks and multi-district inflammation of different severity involving skin, serosal membranes, joints, gastrointestinal tube and central nervous system. The vast majority of these conditions is caused by mutations in genes involved in the control of inflammation and apoptosis mechanisms. The group includes familial Mediterranean fever, mevalonate kinase deficiency syndrome, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndromes, hereditary pyogenic and granulomatous disorders. Their diagnostic identification derives from the combination of clinical and biohumoral data, though can be sometimes confirmed by genotype analysis.

TNFalpha has a key role in cell recruitment, proliferation and death, expression of adhesion molecules and immune responses. In RA, TNFalpha is involved in matrix degradation and osteoclastogenesis. TNFalpha inhibitors are either soluble receptors (etanercept) or monoclonal antibodies (infliximab and adalimumab; golimumab and certolizumab are in development). ⋯ TNFalpha antagonists produce more QALYs than traditional DMARDs, counteracting higher costs. The efficacy, safety, and quality of life benefits of TNFalpha antagonists suggest using them possibly earlier than today, even in clinically moderate RA. Thanks to its overall profile, etanercept might be considered as one of the first-choices in TNFalpha antagonism in RA management.

Comparative Study
[Nailfold capillaroscopy and blood flow laser-doppler analysis of the microvascular damage in systemic sclerosis: preliminary results].
Systemic sclerosis (SSc) is characterized by altered microvascular structure and function. Nailfold videocapillaroscopy (NVC) is the tool to evaluate capillary morphological structure and laser-Doppler Blood flowmetry (LDF) can be used to estimate cutaneous blood flow of microvessels. The aim of this study was to investigate possible relationships between capillary morphology and blood flow in SSc. ⋯ LDF can be employed to evaluate blood perfusion in the microvascular circulation in SSc patients. The blood flow changes observed with the LDF seem to correlate with the severity of microvascular damage in SSc as detected by NVC.

Randomized Controlled Trial Comparative Study
Efficacy and safety of two generic copies of nimesulide in patients with low back pain or knee osteoarthritis.
Two generic bioequivalent copies of the same drug sometimes do not achieve therapeutic equivalence. This may produce adverse events in clinical practice if the therapeutic index of that drug is narrow. ⋯ T and N are equally effective and safe forms of nimesulide for pain management in low back pain and knee osteoarthritis. Price per daily dose is a relevant parameter for making a choice. However, regulations regarding drug bioequivalence criteria should be met for drug marketing authorization submission.
