BACKGROUND AND OBJECTIVES: Auriculotherapy is widely used to relieve painful conditions, therefore, allowing systematic reviews on the subject. However, they did not propose a unified bank of points of possible choice, their possible combinations or described the location of such points, thus making it the objective of this study. CONTENTS: The systematic review of revisions methodology (Overview) was chosen to achieve the proposed goal. The quality of such material was ascertained by the tool Assessment of Multiple Systematic Reviews, and the databases consulted were PEDro database, Pubmed, Scielo, and LILACS. The keywords and boolean index applied were: auriculotherapy AND pain; ear acupuncture AND pain, ear acupressure AND pain; auricular therapy and pain; auricular medicine AND pain. A total of 242 studies were found, but only six were systematic reviews in humans involving pain and auriculotherapy alone (without association with another technique). The methodological quality of the studies was high (8-10/11 Assessment of Multiple Systematic Reviews). There is variability in the neurophysiological explanation of action, many possible disorders that can be approached with auriculotherapy (acute, chronic, trauma, pre-and postoperative pain among others). Auriculotherapy showed to be promising in the remission of the pain, adjunct to the conventional treatment, low risk, cost, and easy administration. CONCLUSION: There are several ways of justifying its neurophysiological effects, and the most used points were ShenMen, the corresponding somatotopic region and the cavum conchae region (vagal stimulation). Auriculotherapy meets the needs of Auriculotherapy: neurophysiology, points to choose, indications and results on musculoskeletal pain conditions: a systematic review of reviews Auriculoterapia: neurofisiologia, pontos de escolha, indicações e resultados em condições dolorosas musculoesqueléticas: revisão sistemática de revisões

Aim: To evaluate the effects of whole-body vibration in the sciatic nerve of oophorectomized Wistar rats, on nociceptive and morphological parameters, such as fiber, axon, and myelin sheath diameters, G ratio, number of nerve fiber and nuclei of Schwann cells, and percentage of connective tissue. Method: Sixty-four rats were used in the groups sham-operate and oophorectomy (n = 32/group); after surgical procedures, each group was subdivided into four: euthanized in the 12 th week, untreated and treated for four weeks; and euthanized in the 16 th week, untreated and treated for eight weeks. The treatment with vibration was performed with a 60 Hz frequencies, for 10 minutes, three days a week, with duration of 4 or 8 weeks. Nociception was evaluated later, in the right paw, by means of a digital analgesimeter, prior to surgery, at the beginning and at the end of the protocol. After the trial period, the sciatic nerve was dissected for examination of the general morphology of the tissue and morphometric analysis; later, the animals were euthanized. Results: Regarding nociception and the morphometry of the sciatic nerve, independent of oophorectomy and treatment time, there was no statistically significant difference within and between groups. Also, the general morphology of the tissue in all groups had characteristics that were preserved. Conclusion: The mechanical vibration did not alter the nociceptive threshold and the morphological aspects of nerve fibers in oophorectomized Wistar rats.

Background Gout traditional treatment consists of anti-inflammatory drugs, analgesics and other rheumatic controllers, however, the occurrence of drug interactions occurs with a certain degree of toxicity, requiring that other methods be used to relieve symptoms. An alternative treatment is cryotherapy due to its capacity for analgesia.

BACKGROUND AND OBJECTIVES: The deleterious effects of rheumatoid arthritis on periarticular tissues have not yet been fully elucidated. Therefore, the search for treatments that can modulate the inflammatory profile and tissue remodeling is pertinent. The present study evaluated the effects of low-level laser therapy (LLLT) on the morphology of periarticular tissues and synovial membrane of rats in a rheumatoid arthritis model. METHODS: Sixty-four male rats were divided into acute (7 days) and chronic (28 days) inflammatory periods, with four groups (n=8) each, being: CG (control group), LG (lesion group), CLaG (laser control group) and LLaG (laser lesion group). The animals of the lesion groups received two inoculations of Freund's Complete Adjuvant at a concentration of 50µL, the first at the base of the tail, and the second at the right knee. The animals in the control groups were injected with isotonic sodium chloride solution. The ClaG and LLaG were treated with 660nm LBI, 5J/cm 2 in the right knee. After the experimental period, the animals were euthanized, and the knees were processed for light microscopy. RESULTS: The CG and CLaG morphological analysis had normal aspects. The LG showed synovitis, femur, and tibia with changes in the periosteum, with inflammatory cells and bone modifications. In the LLaG, the synovial membrane showed signs of improvement. Bone tissue in the chronic period showed morphological aspects, denoting tissue remodeling.
