Objective: To design and validate a nursing screening procedure for diabetic peripheral neuropathy in primary care., Methods: The study was carried out in three phases. 1)Construction of an item bank to form the procedure with an exit score describing the patient's clinical situation. 2)Test and reduction of the initial tentative procedure on a sample of 50 patients using community nurse consultations, eliminating the components with low inter-intra nurse reliability. 3)Validation of the version of the procedure obtained in the previous step on a sample of 106 patients. Calculation of validity and reliability by eliminating components with low criterion validity with respect to the results of the diagnostic electromyography used as a reference standard. Cut-off points were estimated for the use of the procedure as a screening tool, predictive values, performance, internal consistency and inter-nurse reliability., Results: The initial tentative procedure consisted of 12 components that were reduced to 10. In the process of validation of this second version the procedure was simplified again, eventually comprising 6 components, with a cut-off point of 2.5 in its output scale, the point at which it reaches adequate values of sensitivity and negative predictors to be used as a screening instrument. For this cut-off point the inter-intra nurse reliability, criterion validity and predictive validity reached acceptable values., Conclusions: NeuDiaCan as a nursing screening procedure for diabetic peripheral neuropathy in primary care is valid, reliable and easy to use., (Copyright © 2019 Elsevier España, S.L.U.

Background and Objectives: Calcitonin is a polypeptide hormone regulating the metabolism calcium in the body. For many years calcitonin has been used to maintain and improve bone mineral density and to reduce the fracture rate. Many studies showed that calcitonin had analgesic role in several painful circumstances. This pain-ameliorating effect is irrelevant to its osteoclastic inhibitory effect and mechanisms like altering Na+ channel and serotonin receptor expression or hypothesis including the endorphin-mediated mechanism were used to explain this effect. In this study we performed a thorough review on the role of calcitonin as an analgesic agent in different scenarios and investigated the fact that calcitonin can be a feasible medication to relieve pain., Method: Many studies focused on the analgesic effect of calcitonin in several painful circumstances, including acute pains related to vertebral fractures, metastasis, migraine and reflex sympathetic dystrophy as well as neuropathic pains related to spinal injuries or diabetes, and phantom pain. Also, calcitonin was showed to be a useful additive to local anesthesia in the case of controlling postoperative pain or trigeminal neuralgia more effectively. However we faced some contradictory data for conditions like lumbar canal stenosis, complex regional pain syndrome, phantom pain and malignancies., Conclusion: This study showed that calcitonin could be helpful analgesic agent in different painful situations. Calcitonin can be considered an eligible treatment for acute pains related to vertebral fractures and a feasible alternative for the treatment of the acute and chronic neuropathic pains where other medications might fail., (Copyright © 2019 Sociedade Brasileira de Anestesiologia.
