Capsaicin in Pain Management A Spicy Solution to Chronic and Neuropathic Pain

Introduction and purpose: Chronic pain, defined as pain persisting for three months or longer and neuropathic pain which is a type that arises as a result of damage or disease to the somatosensory system, including peripheral fibers (Aβ, Aδ, and C fibers) and central neurons, are serious conditions pose significant challenges for modern medicine. Addressing these challenges often necessitates a multimodal approach to analgesia, involving the use of multiple analgesic agents with different mechanisms of action. Among these agents is capsaicin, a naturally occurring compound found in hot peppers. This study will collect and analyze information about the applications of capsaicin in pain management, its mechanisms of action, efficacy, and safety Brief description of the state of knowledge: Capsaicin is a natural compound found in chili peppers. This alkaloid is a highly selective agonist of the TRPV1 vanilloid receptor. Upon activation of these receptors, skin nociceptors become less sensitive to stimuli. Incorporating capsaicin into standard chronic and neuropathic pain management may enhance, expedite, and streamline the complex process of treatment, ultimately contributing to improved quality of life for patients and communities. It also offers certain benefits in the treatment of obesity, cardiovascular and gastrointestinal pathologies, various types of cancers, neurogenic bladder, and some dermatological conditions. Materials and Methods: Review and summary of research studies available in databases on Google Scholar and PubMed. Summary: Topically applied capsaicin, especially in the form of an 8% patch is a valuable option for treating peripheral chronic and neuropathic pain, including bone and joint pain. The highest quality evidence has been presented in postherpetic neuralgia and HIV-related pain, where treatment efficacy is comparable to standard treatment.

Exploring the relationship between condition severity and health-related quality of life in people with haemophilia A across Europe: a multivariable analysis of data from the CHESS II study

BackgroundHaemophilia A (HA; Factor VIII deficiency) is a congenital X-linked bleeding disorder characterized by trauma-related or spontaneous bleeding events, most notably arising within the intraarticular space and resulting in chronic inflammation and degeneration of affected joints. Endogenous clotting factor activity relative to normal levels determines the severity of HA symptoms, as mild (> 5–40%), moderate (1–5%), or severe (< 1%). Within the current environment of rapid evolution in HA management, we seek to understand the interplay of condition severity and health-related quality of life (HRQoL) to characterise and differentiate unmet needs among people with HA (PwHA).MethodsA generalised linear regression model (GLM) was developed to explore the relationship between HA severity and EQ-5D-5 L index score from adult HA patients sampled in the “Cost of Haemophilia across Europe – a Socioeconomic Survey II” (CHESS II) cross-sectional, retrospective burden of illness study among adults with hereditary haemophilia A or B from eight European countries. HA patients of any severity with no active inhibitors during the 12 months prior to data capture and a completeEQ-5D-5 L response were included. A base GLM model was specified with covariates for demographic and clinical characteristics (age, body mass index, country, employment, HA severity, annual bleeding rate, problem joints, and chronic pain).ResultsOf 381 evaluable patients, 221 (58.0%) had severe HA, 96 (25.2%) had moderate HA, and 64 (16.8%) had mild HA. Among the covariates included in the GLM model and after controlling for haemophilia-related outcomes, a significant association was observed between mild HA and higher EQ-5D-5 L index score (average marginal effects, 0.084; p = 0.016) relative to severe HA. Patient country of residence and magnitude of HA-related chronic pain were also associated with significant differences in index scores, with the latter showing a negative relationship with HRQoL outcomes.ConclusionsCondition severity and chronic pain are significant predictors of HRQoL in PwHA. Durable bleeding protection and effective management of chronic pain have the potential to address unmet treatment needs in this population.

A Review of Remote Monitoring in Neuromodulation for Chronic Pain Management.

Neuromodulation techniques have emerged as promising strategies for managing chronic pain. These techniques encompass various modalities of nerve stimulation, including Spinal Cord Stimulation (SCS), Dorsal Root Ganglion Stimulation (DRG-S), and Peripheral Nerve Stimulation (PNS). Studies consistently demonstrate significant improvements in pain intensity, quality of life, and reduced opioid usage among patients treated with these modalities. However, neuromodulation presents challenges, such as the need for frequent in-person follow-up visits to ensure proper functionality of the implanted device. Our review explored factors impacting compliance in current neuromodulation users and examined how remote monitoring can mitigate some of these challenges. We also discuss outcomes of recent studies related to remote monitoring of neuromodulation. While remote monitoring capabilities for neuromodulation devices is an emerging development, there are promising results supporting its role in improving outcomes for chronic pain patients. Higher patient satisfaction, improved pain control, and reduced caretaker burdens have been observed with the use of remote monitoring. This review discusses the current challenges with neuromodulation therapy and highlights the role of remote monitoring. As the field continues to evolve, understanding the importance of remote monitoring for neuromodulation is crucial for optimizing pain management outcomes.

Pain Management of Refractory Hidradenitis Suppurativa: Case Report

Background: Hidradenitis suppurativa (HS) is a chronic, relapsing, and painful inflammatory condition of the skin. Pain in HS is one of the most common symptoms and has a devastating effect on quality of life. Here, we present a unique case of a patient with HS and pain management guidelines used to treat her condition. Case Report: This is a 42-year-old woman with a history of HS, hypertension, depression who presented with one month of pain in her groin crease, vulva, and rectum. She was recently discharged from the hospital for HS superinfection. She was treated with intravenous and oral antibiotics. She previously tried treatment with acetaminophen, lidocaine 2% jelly, gabapentin 400 mg TID, oxycodone, dilaudid, adalimumab, infliximab, topical clindamycin, intralesional steroid injections, and doxycycline. The pain management specialist recommended continuing treatment with gabapentin 400 mg TID and titrate to 600 mg TID as tolerated, and to follow up with the dermatology team to restart infliximab. Discussion: This case demonstrates a complicated, refractory HS condition that necessitates first, second, and third line treatment modalities. Pain control in HS starts by having best control of the underlying disease. The United States and Canadian Hidradenitis Suppurativa Foundations clinical guidelines suggest acute pain management should include topical analgesics (ie, lidocaine), oral acetaminophen, and oral nonsteroidal anti-inflammatory drugs. Chronic pain management should focus on a multidisciplinary approach. Clinical guidelines recommend escalating oral analgesics for pain that doesn’t respond to first-line agents. Opiate use should follow the World Health Organization pain ladder of tramadol, codeine, hydrocodone, and morphine. Neuropathic pain can be treated with pregabalin or gabapentin, titrated as tolerated by patients. Chronic HS lesions can be treated with wide local scalpel, CO2, or electrosurgical excision, and recurrent nodules can be deroofed or excised. Superior hypogastric plexus block and/or ganglion impar block can be considered for refractory cases. Conclusion: HS is an extremely painful condition severely affecting quality of life. Adequate pain management is vital, and a stepwise approach is recommended.

Mechanism of Action of Mindfulness-Based Interventions for Pain Relief-A Systematic Review.

Background: Currently, no systematic evidence synthesis of the mechanism of action of mindfulness-based approaches exists for pain conditions. Aim: To identify and synthesize experimental and clinical studies examining aspects of the mechanism of action of mindfulness for pain relief. Methods: The following databases and search interfaces were searched: Embase (via Embase.com) and Medline (via PubMed). Additional references were identified via bibliographies of included studies. The following were the inclusion criteria applied: (1) original studies published in peer-reviewed journals, (2) in adult populations that (3) examined the mechanism of action of mindfulness meditation on pain outcomes or (4) provided conclusions regarding the potential mechanism of action of mindfulness meditation. The studies were selected by two independent reviewers. Discrepancies were resolved by discussion. Results: A total of 21 studies published in English met the inclusion criteria, of which 5 studies were clinical studies, which included patients with chronic pain, and 16 studies used experimental pain induction. The investigation into brain mechanisms through functional magnetic resonance imaging and diffusion tensor imaging revealed mindfulness meditation's ability to modulate brain activity, particularly in the anterior cingulate cortex, anterior insula, and orbitofrontal cortex, and to enhance structural and functional connectivity in regions associated with pain perception. Regarding the role of opioids, findings across five studies indicated that the analgesic effects of mindfulness are maintained even when opioid receptors are blocked, suggesting a nonopioidergic pathway for pain modulation. Pain perception studies highlighted that mindfulness practices foster pain acceptance and modify pain control beliefs, serving as key mediators in improving pain outcomes. For experienced versus novice mindfulness practitioners, results demonstrated that long-term practice enhances pain threshold and reduces pain unpleasantness through increased activity in salience and attentional control regions. Conclusion: This systematic review highlights mindfulness meditation as a multifaceted approach to pain management, utilizing mechanisms such as cognitive and emotional reappraisal, nonopioidergic pathways, and enhanced attention in control regions. It emphasizes the role of mindfulness in fostering pain acceptance and altering pain control perceptions, showcasing its broad impact on the neurological and experiential dimensions of pain. However, the predominance of studies on healthy subjects and methodological variations across experiments necessitates careful interpretation of the findings. The review calls for further research to explore the mechanisms of mindfulness in chronic pain populations more deeply, distinguishing the specific effects of mindfulness from nonspecific effects and expanding its applicability in clinical settings for chronic pain management.

Opioid Use and Gut Dysbiosis in Cancer Pain Patients.

Opioids are commonly used for the management of severe chronic cancer pain. Their well-known pharmacological effects on the gastrointestinal system, particularly opioid-induced constipation (OIC), are the most common limiting factors in the optimization of analgesia, and have led to the wide use of laxatives and/or peripherally acting mu-opioid receptor antagonists (PAMORAs). A growing interest has been recently recorded in the possible effects of opioid treatment on the gut microbiota. Preclinical and clinical data, as presented in this review, showed that alterations of the gut microbiota play a role in modulating opioid-mediated analgesia and tolerability, including constipation. Moreover, due to the bidirectional crosstalk between gut bacteria and the central nervous system, gut dysbiosis may be crucial in modulating opioid reward and addictive behavior. The microbiota may also modulate pain regulation and tolerance, by activating microglial cells and inducing the release of inflammatory cytokines and chemokines, which sustain neuroinflammation. In the subset of cancer patients, the clinical meaning of opioid-induced gut dysbiosis, particularly its possible interference with the efficacy of chemotherapy and immunotherapy, is still unclear. Gut dysbiosis could be a new target for treatment in cancer patients. Restoring the physiological amount of specific gut bacteria may represent a promising therapeutic option for managing gastrointestinal symptoms and optimizing analgesia for cancer patients using opioids.

Anesthetic management in orthopaedic surgery for rheumatic patients

Patients with rheumatic diseases frequently require orthopaedic surgeries due to progressive joint damage and deformities. These patients pose unique challenges for anesthesiologists due to systemic involvement, altered anatomy, and chronic pain management needs. This review explores optimal anesthetic strategies to improve surgical outcomes and enhance patient safety in this vulnerable population. Preoperative assessment is crucial for identifying systemic manifestations of rheumatic diseases, including cardiovascular, respiratory, and renal involvement, which can significantly impact anesthetic management. A thorough evaluation helps tailor the anesthetic plan to individual patient needs, ensuring better perioperative care.Regional anesthesia, particularly neuraxial blocks and peripheral nerve blocks, offers significant benefits over general anesthesia in this population. These techniques can reduce postoperative pain, enhance recovery times, and decrease opioid consumption. However, the presence of spinal deformities and anticoagulation therapy in these patients requires careful consideration and meticulous planning. Multimodal analgesia, combining regional techniques with systemic medications, is recommended to manage chronic pain and minimize opioid use postoperatively. Effective pain management strategies are essential for improving postoperative outcomes and patient satisfaction.

Long-Term Outcome and Predictors of Transversus Abdominis Plane Block for Chronic Post-Hernioplasty Pain.

Background/Objectives: Different analgesic techniques have been used in the clinical management of chronic post-hernioplasty pain (CPHP), with variable results. This study aimed to investigate clinical factors associated with long-term outcome of the transversus abdominal plane (TAP) block for CPHP. Methods: We retrospectively analyzed 26 patients with CPHP who were treated with single or multiple TAP blocks with local anesthetic and steroid. Patients were evaluated for pain and neuropathic pain intensity by a Numerical Rating Scale (NRS) and the painDETECT questionnaire (PDQ), for anxiety and depression by the Hospital Anxiety and Depression Scale, and for quality of life by the 12-item Short Form Health Survey (SF12). Results: At 6 months post-treatment, 20 patients (77%) presented substantial (>50%) or moderate (30-50%) CPHP relief and were considered responders. In responders, the 24-h average and maximum NRS pain significantly declined (p < 0.01) from 7.3 ± 1.3 to 2.6 ± 2.1 and from 8.8 ± 1.5 to 5.1 ± 2.0, and the neuropathic PDQ score from 9.1 ± 3.2 to 6.1 ± 1.3; the physical SF12 score improved from 36.5 ± 5.8 to 44.3 ± 7.5 (p < 0.01). Six patients failed to achieve a significant CPHP improvement and were considered non-responders. Non-responders presented a significantly (p < 0.05) longer CPHP, higher body mass index and neuropathic symptoms, and more frequent anxiety, depression, diabetes, and fibromyalgia. Conclusions: The TAP block with local anesthetic and steroid should be considered as a therapeutic option for CPHP. However, medical and psychiatric comorbidities negatively impact the TAP block effectiveness for CPHP.

Low-intensity transcranial focused ultrasound suppresses pain by modulating pain-processing brain circuits

AbstractThere is an urgent and unmet clinical need to develop nonpharmacological interventions for chronic pain management because of the critical side effects of opioids. Low-intensity transcranial focused ultrasound (tFUS) is an emerging noninvasive neuromodulation technology with high spatial specificity and deep brain penetration. Here, we developed a tightly focused 128-element ultrasound transducer to specifically target small mouse brains using dynamic focus steering. We demonstrate that tFUS stimulation at pain-processing brain circuits can significantly alter pain-associated behaviors in mouse models in vivo. Our findings indicate that a single-session focused ultrasound stimulation to the primary somatosensory cortex (S1) significantly attenuates heat pain sensitivity in wild-type mice and modulates heat and mechanical hyperalgesia in a humanized mouse model of chronic pain in sickle cell disease. Results further revealed a sustained behavioral change associated with heat hypersensitivity by targeting deeper cortical structures (eg, insula) and multisession focused ultrasound stimulation to S1 and insula. Analyses of brain electrical rhythms through electroencephalography demonstrated a significant change in noxious heat hypersensitivity-related and chronic hyperalgesia–associated neural signals after focused ultrasound treatment. Validation of efficacy was carried out through control experiments, tuning ultrasound parameters, adjusting interexperiment intervals, and investigating effects on age, sex, and genotype in a head-fixed awake model. Importantly, tFUS was found to be safe, causing no adverse effects on motor function or the brain’s neuropathology. In conclusion, the validated proof-of-principle experimental evidence demonstrates the translational potential of novel focused ultrasound neuromodulation for next-generation pain treatment without adverse effects.

Reimagining chronic pain management: the case for integrated care in India

PurposeThe viewpoint essay focusses on the significance of integrated care (IC) for chronic pain in India, in an attempt to reflect on how pain management and care can be made more accessible and available to patients.Design/methodology/approachThis reflective essay invites looking at chronic pain beyond biomedical perspectives. Insights from the medical humanities and the social sciences are used to emphasise chronic pain as a psychosocial and socio-political phenomenon and not just a biomedical category.FindingsThe essay argues that there are several challenges and barriers to the recognition and validation of chronic pain as a speciality.Originality/valueIC has not received sufficient attention in the Indian context, where medical curricula and training do not sufficiently include an understanding of the multi-faceted aspects surrounding chronic pain. By highlighting the role of humanistic approaches to effectively bridge the gap, this viewpoint essay illustrates the significance of drawing on an integrated or holistic healthcare framework.

Health Resource Utilization and Cost Impact of Integrative Medicine Services for Newly Diagnosed Chronic Pain Patients.

Background: Integrative medicine (IM) is the healing-oriented practice of medicine that emphasizes the relationship between practitioner and patient. It considers the whole person, their environment, lifestyle, and social and cultural factors. It is evidence based and makes use of all appropriate therapies, conventional and complimentary. Objective: To evaluate the impact of IM services on health outcomes and care costs of chronic pain management patients compared with standard care. Methods: This article uses University of New Mexico hospital billing data from 10/2016 to 09/2019 to identify patients with nervous system or musculoskeletal pain. A total of 1,304 patients were matched using propensity scores into IM services (treatment: 652) and standard care (control: 652) cohorts for difference-in-differences analysis. The patients were matched based on age, sex, race, zip code, insurance type, ICD-10s, prescriptions, health care events, and medical claim costs. Results: Patients who used IM services had better health outcomes and lower costs at 3-month, 6-month, and 12-month follow-up. At the 12-month follow-up, the IM group showed a 19% decrease in utilization of inpatient care, a 37% decrease in Emergency Department utilization, and an 11.3% reduction in claim costs compared with the control group. Conclusion: Patients who utilize IM services as part of chronic pain management have overall lower health care costs and better health outcomes. Unfortunately, in the health system studied, less than 3% of patients utilize these services. Promotion of and education about IM services should be aimed at both patients and their providers.

Effect of 8 weeks of cognitive behavioral therapy versus 8 weeks core stabilization training in the management of subjects with non-specific low back pain: a randomized controlled trial

BackgroundPatients with chronic pain usually regard pain as a stressful situation. The literature revealed that chronic pain is associated with social and cognitive dysfunction. Recently, the literature started to support using cognitive behavioral therapy to reduce the effect of chronic nonspecific low back pain.ObjectivesThe study aimed to assess the effect of cognitive behavioral therapy versus core stabilization training in the treatment of subjects with non-specific chronic low back pain.MethodsNinety subjects were enrolled in the current study, with mean age (32.30 ± 4.38) and mean weight (72.27 ± 10.88). They were equally randomized into three equal groups A, B, and C using opaque envelopes and computer-generalized numbers. Group A received cognitive behavioral therapy plus traditional treatment, group B received a core stabilization training program plus traditional treatment, and group C received only traditional treatment. Visual Analog Scale, Fear Avoidance and Belief Questionnaire, and Oswestry Disability Index were used pre- and post-treatment to measure the outcomes in response to the treatment plans.ResultsStatistical analysis revealed that there was a significant decrease in the Visual Analog Scale, Fear Avoidance and Belief Questionnaire, and Oswestry Disability Index post-treatment compared with pre-treatment in group A (P < 0.001), group B (P < 0.001), and group C (P < 0.001). Also, the results revealed that there was a significant decrease in the Visual Analog Scale, Fear Avoidance and Belief Questionnaire work/lifestyle, and Oswestry Disability Index of group A compared with group B (P < 0.05) and group C (P < 0.001) and a significant decrease in outcome measures in group B compared with group C (P < 0.05).ConclusionThe results of the current study support the involvement of cognitive therapy in the management of chronic pain as it guides the patient to be aware of the underlying mechanism of chronic pain and the management maneuvers to overcome such pain. Also, the results provide credit to cognitive behavioral therapy in terms of long-term relief of chronic pain.

A Narrative Review of Ultrasound-Guided and Landmark-based Percutaneous Cryoneurolysis for the Management of Acute and Chronic Pain.

Cryoneurolysis refers to the process of reversibly ablating peripheral nerves with extremely cold temperatures to provide analgesia for weeks to months. With ultrasound-guidance or landmark-based techniques, it is an effective modality for managing both acute and chronic pain. In this review, we summarize the reported literature behind its potential applications and efficacy. Here, we summarize several studies (from case reports to clinical trials) describing the use of ultrasound-guided and landmark-based cryoneurolysis for acute and chronic pain. Acute pain indications included pain related to knee arthroplasty, limb amputations, mastectomies, shoulder surgery, rib fractures, and burn. Chronic pain indications included chronic knee pain (due to osteoarthritis), shoulder pain, painful neuropathies, postmastectomy pain syndrome, phantom limb pain, facial pain/headaches, foot/ankle pain, inguinal pain, and sacroiliac joint pain. For both acute and chronic pain indications, more high quality randomized controlled clinical trials are needed to definitively assess the efficacy of cryoneurolysis versus other standard therapies for a multitude of pain conditions.

Understanding the epidemiology and perceived efficacy of cannabis use in patients with chronic musculoskeletal pain

BackgroundThe belief that cannabis has analgesic and anti-inflammatory properties continues to attract patients with chronic musculoskeletal (MSK) pain towards its use. However, the role that cannabis will play in the management of chronic MSK pain remains to be determined. This study examined 1) the rate, patterns of use, and self-reported efficacy of cannabis use among patients with chronic MSK pain and 2) the interest and potential barriers to cannabis use among patients with chronic MSK pain not currently using cannabis.MethodsSelf-reported cannabis use and perceived efficacy were prospectively collected from chronic MSK pain patients presenting to the Orthopaedic Clinic at the University Health Network, Toronto, Canada. The primary dependent variable was current or past use of cannabis to manage chronic MSK pain; bivariate and multivariable logistic regression were used to identify patient characteristics independently associated with this outcome. Secondary outcomes were summarized descriptively, including self-perceived efficacy among cannabis users, and interest as well as barriers to cannabis use among cannabis non-users.ResultsThe sample included 629 patients presenting with chronic MSK pain (mean age: 56±15.7 years; 56% female). Overall, 144 (23%) reported past or present cannabis use to manage their MSK pain, with 63.7% perceiving cannabis as very or somewhat effective and 26.6% considering it as slightly effective. The strongest predictor of cannabis use in this study population was a history of recreational cannabis use (OR 12.7, p<0.001). Among cannabis non-users (N=489), 65% expressed interest in using cannabis to manage their chronic MSK pain, but common barriers to use included lack of knowledge regarding access, use and evidence, and stigma.ConclusionsOne in five patients presenting to an orthopaedic surgeon with chronic MSK pain are using or have used cannabis with the specific intent to manage their pain, and most report it to be effective. Among non-users, two-thirds reported an interest in using cannabis to manage their MSK pain, but common barriers to use existed. Future double-blind placebo-controlled trials are required to understand if this reported efficacy is accurate, and what role, if any, cannabis may play in the management of chronic MSK pain.
