Neuropathic pain (NP) is a very frequent and unrecognized condition in clinical practice. Therefore, it is important to have a reliable instrument to assess pain subtypes in various cultures. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) has been widely used and validated in many countries. Up to now, there has been no reliability study of this instrument in Brazil. ⋯ This LANSS version was found to be a reliable instrument for the evaluation of pain complaints due to a variety of causes. The profile of pain scores was similar to that observed in other countries.

Randomized Controlled Trial
Randomized double-blind sham-controlled crossover study of short-term effect of percutaneous electrical nerve stimulation in neuropathic pain.
Percutaneous electrical nerve stimulation (PENS) is an electrical neuromodulation technique that has shown its therapeutic potential in various chronic pain conditions over the past few years, but well-blinded controlled studies are lacking. ⋯ PENS therapy appears to be effective in providing short-term pain relief in chronic pain conditions. Studies, involving larger sample sizes and longer follow-up are recommended.

We assessed primary care clinician-provided guideline-concordant care as documented in patients' medical records, predictors of documented guideline-concordant care, and its association with pain-related functioning. Patients were participants in a randomized trial of collaborative care for chronic musculoskeletal pain. The intervention featured patient and primary care clinician education, symptom monitoring and feedback to clinicians by the intervention team. ⋯ As measured by medical record review, additional training and clinician feedback did not increase provision of documented guideline-concordant pain care, and adherence to guidelines by primary care clinicians did not improve clinical outcomes for patients with chronic musculoskeletal pain.

Randomized Controlled Trial
Effects of corticosteroids injection in rotator cuff tears.
The aim of this study was to evaluate the effect of intraarticular injections of corticosteroids (triamcinolone) in patients with symptomatic rotator cuff tears (RCT). ⋯ Our study indicates that intraarticular injection of triamcinolone improves pain relief for 3 months in RCT and its action is not prolonged or potentiated by two injections of the drug done at 21-day intervals.

The physiological sensation of pain and rapid response to stimuli serve as an adaptive way to avoid harmful situations. Our purpose was to investigate why this protection disappears or almost disappears for patients with congenital indifference to pain (CIP). ⋯ We speculate that the mutations may be the cause of partial deletion of pain perceptionin in our probands, and the novel polymorphism V1104L may have a predictive role in the pain sensation of healthy individuals.
