Although pain is indispensable for survival, chronic pain places a heavy burden on humans. As the efficacy of opioid treatment is limited, the development of alternative methods of pain relief without medication is desirable. Recently, we have developed a novel method of physical analgesia using an adhesive "pyramidal thorn patch." When we apply about 3 trials of these patches on the skin of a pain region, the pain region moves toward the spinal cord like a "cutaneous rabbit," and finally, the pain vanishes. ⋯ Transient receptor potential (TRP) channels serve as mechanosensitive channels within these mechanoreceptors. We further propose that activation of the nerves connected with the mechanoreceptors releases oxytocin, which has an antinociceptive function and activates TRP channels to hyperpolarize the pain signal nerves. We believe that our system will pave the way for alternative pain treatment.

Pain is the leading cause of emergency department (ED) visits for individuals living with sickle cell disease (SCD). The care that is delivered in the ED is often cited by patients with SCD as the area of health care in greatest need of improvement. In 2014, the National Heart, Lung, and Blood Institute released guidelines for the care of SCD, including recommendations for the management of acute sickle cell pain in the ED. ⋯ Presented in this article are 4 tenets of implementing guideline-adherent emergency sickle cell care gleaned from the available literature and continuous quality improvement efforts at our institution. These include: (1) strategies to reduce negative provider attitudes toward patients with SCD; (2) strategies to reduce time-to-first-dose of analgesic medication; (3) strategies to improve ED pain care beyond the first dose of medication; and (4) strategies to improve ED patient safety. Application of the principles discussed within can improve patient and provider satisfaction, quality, and safety.

Patients with sickle cell disease (SCD) suffer from intense pain that can start during infancy and increase in severity throughout life, leading to hospitalization and poor quality of life. A unique feature of SCD is vaso-occlusive crises (VOCs) characterized by episodic, recurrent, and unpredictable episodes of acute pain. Microvascular obstruction during a VOC leads to impaired oxygen supply to the periphery and ischemia reperfusion injury, inflammation, oxidative stress, and endothelial dysfunction, all of which may perpetuate a noxious microenvironment leading to pain. ⋯ This review presents up-to-date developments in our understanding of the pathobiology of pain in SCD. To help focus future research efforts, major gaps in knowledge are identified regarding how sickle pathobiology evokes pain, pathways specific to chronic and acute sickle pain, perception-based targets of "top-down" mechanisms originating from the brain and neuromodulation, and how pain affects the sickle microenvironment and pathophysiology. This review also describes mechanism-based targets that may help develop novel therapeutic and/or preventive strategies to ameliorate pain in SCD.

It is hypothesised that a single injection fascia iliaca compartment block (FICB) administered in the pre-operative setting provides better analgesic control for traumatic hip fractures and is not associated with major adverse effects. Systemic analgesics, whilst effective, could lead to cardiovascular, respiratory and cognitive impairment. As a consequence, undertreatment of acute pain remains prevalent in adult patients with hip fractures, with a consistent decline seen in analgesic administration with age. ⋯ Out of 3757 citations, eight RCTs were included in the final quantitative analysis, comprising of 645 participants. Acute pain was significantly reduced in FICB during positioning and movement, standardised mean difference (SMD)=-1.82 (95% CI:-2.26 to -1.38, p<0.00001) but was variable at rest (p=0.20). There was a reduced incidence of analgesia breakthrough (n=57 versus n=73), drowsiness/sedation (n=1 versus n=22), desaturation (n=0 versus n=4) and nausea and vomiting (n=3 versus n=7) in the FICB arm. There were similar numbers of patients across both arms that reported localised bruising (n=3). Only one study was at low risk of bias.emermed;34/12/A891-a/F1F1F1Figure 1emermed;34/12/A891-a/F2F2F2Figure 2 CONCLUSIONS: FICB is superior in controlling acute pre-operative pain in adult patients with traumatic hip fractures. The benefit is more evident during positioning and mobilisation of the limb. FICB has a better safety profile and reduces dependency on systemic analgesia.

There is no consensus on the management of low back pain in the ED and evidence suggests that these patients are likely to receive unwarranted imaging and inappropriate opioid prescription.The purpose of this study is to review the available literature pertaining to the clinical management of acute low back pain in the ED. ⋯ More high quality trials are needed to determine an evidence-based management protocol for the treatment of acute low back pain in the ED.
