Improvement of Pain and Function After Use of a Topical Pain Relieving Patch: Results of the RELIEF Study

Use of Nanotechnology as an Alternative to Opioids for Post-operative Pain Management Following TKA

Introduction

In response to the current opioid crisis, there is a great interest to develop non-pharmacologic approaches to post-operative pain management for patients undergoing total knee arthroplasty (TKA).

Case Report

We report a case of a patient whose post-operative pain following TKA was managed using the newly designed NeuroCuple™ device, a patch based on the use of nanotechnology. The NeuroCuple™ device was placed above the knee by the patient at home. The use of the NeuroCuple™ device allowed the patient completely avoid the use of any opioids at home.

Conclusion

Our report suggests that the use of the NeuroCuple™ device may represent an interesting alternative to opioids for the peri-operative management of pain following a primary, unilateral TKA.

Complementary and alternative medicines chosen for specific health problems: Internet survey using the I-CAM-Q in Japan: A STROBE-compliant cross-sectional study

This study investigated the different complementary and alternative medicines (CAMs) adopted by people in Japan, as well as the health problems treated with CAMs. Understanding more about this topic will facilitate the appropriate incorporation of CAMs into conventional medicine when treating health problems. Data were collected through an online survey based on the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q). The study examined CAM utilization among people aged 20 years or older; 164 valid responses were collected (18.9%). We adopted a cross-sectional design. We then compared the relationships between the specific health problems reported by participants, their self-help practices, and the kinds of healthcare specialists consulted. We also examined participants' reasons for using CAMs and their responses regarding the usefulness of the CAMs adopted. We found that self-help/CAM practices differed for specific health problems. Participants with musculoskeletal and heart problems were more likely to use poultices. Those with respiratory and digestive problems were more likely to practice yoga, tai chi, and qigong. Those with digestive and neurological problems were more likely to use aromatherapy. The I-CAM-Q questionnaire also revealed the purpose and usefulness of the CAMs utilized as well as the participants' attitudes regarding conventional medicine. The study showed that participants find physicians less helpful than other options for treating their health problems. Additionally, when asked whether it was helpful to consult with a specific professional for health problems, there was a higher percentage of participants who answered "Very helpful" for professionals, like massage, judo, acupuncture, and moxibustion therapists, than for physicians. The results of this study will help to inform medical providers of the most appropriate types of CAMs for dealing with various health problems.

The distinctive role of menthol in pain and analgesia: Mechanisms, practices, and advances

Menthol is an important flavoring additive that triggers a cooling sensation. Under physiological condition, low to moderate concentrations of menthol activate transient receptor potential cation channel subfamily M member 8 (TRPM8) in the primary nociceptors, such as dorsal root ganglion (DRG) and trigeminal ganglion, generating a cooling sensation, whereas menthol at higher concentration could induce cold allodynia, and cold hyperalgesia mediated by TRPM8 sensitization. In addition, the paradoxical irritating properties of high concentrations of menthol is associated with its activation of transient receptor potential cation channel subfamily A member 1 (TRPA1). Under pathological situation, menthol activates TRPM8 to attenuate mechanical allodynia and thermal hyperalgesia following nerve injury or chemical stimuli. Recent reports have recapitulated the requirement of central group II/III metabotropic glutamate receptors (mGluR) with endogenous κ-opioid signaling pathways for menthol analgesia. Additionally, blockage of sodium channels and calcium influx is a determinant step after menthol exposure, suggesting the possibility of menthol for pain management. In this review, we will also discuss and summarize the advances in menthol-related drugs for pathological pain treatment in clinical trials, especially in neuropathic pain, musculoskeletal pain, cancer pain and postoperative pain, with the aim to find the promising therapeutic candidates for the resolution of pain to better manage patients with pain in clinics.

Back pain and treatment seeking among community-dwelling older adults: Findings from a population-based survey

This study explores the prevalence and factors associated with back pain and treatment seeking of older people. We used data from the Longitudinal Aging Study in India (LASI), 2017-18. A sample of 31,464 older adults aged 60 years and above was considered for this study. Chi-square test was used to find the significance level for bivariate associations. Additionally, Heckprobit selection model was employed to fulfill the objectives. Among 34% of the participants suffering from back pain, 46.2% used external application, followed by analgesics (40.8%) and therapy (6.6%). Older adults with higher education had a higher probability of seeking therapy than those with no or primary education [β:0.25; CI:0.03,0.48]. Participants from the highest wealth quintile had higher probability of seeking therapy than those from the lowest [β:0.41; CI:0.23,0.58]. The use of therapy, which is globally recommended first line of management for back pain, was least utilized and must be promoted.
