Current Pain and Headache Reports最新文献

Purpose of the review: Acute postoperative pain impacts a significant number of patients and is associated with various complications, such as a higher occurrence of chronic postsurgical pain as well as increased morbidity and mortality.

Recent findings: Opioids are often used to manage severe pain, but they come with serious adverse effects, such as sedation, respiratory depression, postoperative nausea and vomiting, and impaired bowel function. Therefore, most enhanced recovery after surgery protocols promote multimodal analgesia, which includes adjuvant analgesics, to provide optimal pain control. In this article, we aim to offer a comprehensive review of the contemporary literature on adjuvant analgesics in the management of acute pain, especially in the perioperative setting. Adjuvant analgesics have proven efficacy in treating postoperative pain and reducing need for opioids. While ketamine is an established option for opioid-dependent patients, magnesium and α2-agonists have, in addition to their analgetic effect, the potential to attenuate hemodynamic responses, which make them especially useful in painful laparoscopic procedures. Furthermore, α2-agonists and dexamethasone can extend the analgesic effect of regional anesthesia techniques. However, findings for lidocaine remain inconclusive.

Purpose of review: This review provides an overview of the current and future role of artificial intelligence (AI) and virtual reality (VR) in addressing the complexities inherent to the diagnosis, classification, and management of headache disorders.

Recent findings: Through machine learning and natural language processing approaches, AI offers unprecedented opportunities to identify patterns within complex and voluminous datasets, including brain imaging data. This technology has demonstrated promise in optimizing diagnostic approaches to headache disorders and automating their classification, an attribute particularly beneficial for non-specialist providers. Furthermore, AI can enhance headache disorder management by enabling the forecasting of acute events of interest, such as migraine headaches or medication overuse, and by guiding treatment selection based on insights from predictive modeling. Additionally, AI may facilitate the streamlining of treatment efficacy monitoring and enable the automation of real-time treatment parameter adjustments. VR technology, on the other hand, offers controllable and immersive experiences, thus providing a unique avenue for the investigation of the sensory-perceptual symptomatology associated with certain headache disorders. Moreover, recent studies suggest that VR, combined with biofeedback, may serve as a viable adjunct to conventional treatment. Addressing challenges to the widespread adoption of AI and VR in headache medicine, including reimbursement policies and data privacy concerns, mandates collaborative efforts from stakeholders to enable the equitable, safe, and effective utilization of these technologies in advancing headache disorder care. This review highlights the potential of AI and VR to support precise diagnostics, automate classification, and enhance management strategies for headache disorders.

Objective: Chronic neck pain, a prevalent health concern characterized by frequent recurrence, requires exploration of treatment modalities that provide sustained relief. This systematic review and meta-analysis aimed to evaluate the durable effects of acupuncture on chronic neck pain.

Methods: We conducted a literature search up to March 2024 in six databases, including PubMed, Embase, and the Cochrane Library, encompassing both English and Chinese language publications. The main focus of evaluation included pain severity, functional disability, and quality of life, assessed at least 3 months post-acupuncture treatment. The risk of bias assessment was conducted using the Cochrane Risk of Bias 2.0 tool, and meta-analyses were performed where applicable.

Results: Eighteen randomized controlled trials were included in the analysis. Acupuncture as an adjunct therapy could provide sustained pain relief at three (SMD: - 0.79; 95% CI - 1.13 to - 0.46; p < 0.01) and six (MD: - 18.13; 95% CI - 30.18 to - 6.07; p < 0.01) months post-treatment. Compared to sham acupuncture, acupuncture did not show a statistically significant difference in pain alleviation (MD: - 0.12; 95% CI - 0.06 to 0.36; p = 0.63). However, it significantly improved functional outcomes as evidenced by Northwick Park Neck Pain Questionnaire scores 3 months post-treatment (MD: - 6.06; 95% CI - 8.20 to - 3.92; p < 0.01). Although nine studies reported an 8.5%-13.8% probability of adverse events, these were mild and transitory adverse events.

Conclusion: Acupuncture as an adjunct therapy may provide post-treatment pain relief lasting at least 3 months for patients with chronic neck pain, although it is not superior to sham acupuncture, shows sustained efficacy in improving functional impairment for over 3 months, with a good safety profile.

Purpose of review: The present investigation evaluated integration of novel medication technology to enhance treatment options, while improving patient outcomes in acute pain management. In this regard, we focused on determining the role of development and utilization of cutting-edge pharmaceutical advancements, such as targeted drug delivery systems, as well as non-pharmacologic interventions in addressing acute pain states. Further research in this area is warranted related to the need for increased patient comfort and reduced adverse effects.

Recent findings: Recent innovations and techniques are discussed including pharmacologic drugs targeting sodium and calcium channels, peptide-based pharmacologic drugs, and non-medicinal methods of alleviating pain such as soothing music or virtual reality. The present investigation included review of current literature on the application of these innovative technologies, analyzing mechanisms of action, pharmacokinetics, and clinical effectiveness. Our study also investigated the potential benefits in terms of pain relief, reduced side effects, and improved patient adherence. The research critically examines the challenges and considerations associated with implementing these technologies in acute pain management, considering factors like cost, accessibility, and regulatory aspects. Additionally, case studies and clinical trials are highlighted which demonstrate practical implications of these novel medication technologies in real-world scenarios. The findings aim to provide healthcare professionals with a comprehensive understanding of the evolving landscape in acute pain management while guiding future research and clinical practices toward optimizing their use in enhancing patient care.

Purpose of review: Postoperative nerve injury after nerve block is complex and multifactorial. The mechanisms, etiologies, and risk factors are explored. This review article conducts a literature search and summarizes current evidence and best practices in prevention of nerve injury.

Recent findings: Emerging technology such as ultrasound, injection pressure monitors, and nerve stimulators for peripheral nerve block have been incorporated into regular practice to reduce the rate of nerve injury. Studies show avoidance of intrafascicular injection, limiting concentrations/volumes of local anesthetic, and appropriate patient selection are the most significant controllable factors in limiting the negative consequences of nerve block. Peripheral nerve injury is an uncommon occurrence after nerve block and is obscured by surgical manipulation, positioning, and underlying neural integrity. Underlying neural integrity is not always evident despite an adequate history and physical exam. Surgical stress, independently of nerve block, may exacerbate these neurologic disease processes and make diagnosing a postoperative nerve injury more challenging. Prevention of nerve injury by surgical teams, care with positioning, and avoidance of intrafascicular injection with nerve block are the most evidence-based practices.

Purpose of review: Spinal cord stimulation (SCS) is an increasingly utilized therapy for the treatment of neuropathic pain conditions. Though minimally invasive and reversable, there are several important device-related complications that physicians should be aware of before offering this therapy to patients. The aim of this review is to synthesize recent studies in device-related SCS complications pertaining to cylindrical lead implantation and to discuss etiologies, symptoms and presentations, diagnostic evaluation, clinical implications, and treatment options.

Recent findings: Device-related complications are more common than biologic complications. Device-related complications covered in this review include lead migration, lead fracture, lead disconnection, generator failure, loss of charge, generator flipping, hardware related pain, and paresthesia intolerance. The use of SCS continues to be an effective option for neuropathic pain conditions. Consideration of complications prior to moving forward with SCS trials and implantation is a vital part of patient management and device selection. Knowledge of these complications can provide physicians and other healthcare professionals the ability to maximize patient outcomes.

Purpose of review: This review investigates the roles of artificial intelligence (AI) and virtual reality (VR) in enhancing cognitive pain therapy for chronic pain management. The work assesses current research, outlines benefits and limitations and examines their potential integration into existing pain management methods.

Recent findings: Advances in VR have shown promise in chronic pain management through immersive cognitive therapy exercises, with evidence supporting VR's effectiveness in symptom reduction. AI's personalization of treatment plans and its support for mental health through AI-driven avatars are emerging trends. The integration of AI in hybrid programs indicates a future with real-time adaptive technology tailored to individual needs in chronic pain management. Incorporating AI and VR into chronic pain cognitive therapy represents a promising approach to enhance management by leveraging VR's immersive experiences and AI's personalized tactics, aiming to improve patient engagement and outcomes. Nonetheless, further empirical studies are needed to standardized methodologies, compare these technologies to traditional therapies and fully realize their clinical potential.

Purpose of review: Pain management following cardiac surgery is a critical component in optimizing both short- and long-term patient outcomes, with poor pain management associated with significant acute and chronic opioid use, opioid dependence and a significant rate of opioid related adverse drug events. The significant burden of both acute and chronic pain following cardiac surgery has given rise to the need for multimodel analgesic strategies, to optimize outcomes and minimize side effects.

Recent findings: While significant research has focused recently on the additive value of peripheral nerve blocks, less emphasis has been given to the value of non-opioid based analgesics in preference to traditional opioid based anesthetic and analgesic strategies. In this review, we examine the evidence for several common analgesics, highlighting the evidence supporting efficacy following cardiac surgery, as well as the safety concerns with each agent. We demonstrate the value of a multimodal analgesic strategy to reduce pain scores and improve patient-centered outcomes, and highlight the need for further studies of combination analgesic strategies.

Purpose of review: Patient-centred care (PCC) is deemed essential in the rehabilitation of musculoskeletal pain. Integrating such care within a biopsychosocial framework, enables to address all facets of the individual pain experience, and to manage the individual instead of the condition. This narrative review describes the status quo of PCC physiotherapy management of people with headache within a biopsychosocial model. PubMed, EMBASE, Web of Science, Scopus were searched (update 07.05.2024). The search-query comprised terminology relating to "headache", "patient-centred", "biopsychosocial", "physiotherapy". Additional eligibility criteria were reviews, trials, cohort, case report, case-control studies in English, Dutch, French.

Recent findings: Gaps are exposed in patient-centred physiotherapy management of migraine, tension-type headache, and cervicogenic headache. While a biopsychosocial approach is advised to manage migraine and tension-type headache, its use in clinical practice is not reflected by the literature. A biopsychosocial approach is not advised in cervicogenic headache. Psychosocial-lifestyle interventions are mainly delivered by health-care providers other than physiotherapists. Additionally, psychologically-informed practice is barely introduced in physiotherapy headache management. Though, managing the social context within a biopsychosocial framework is advised, the implementation by physiotherapists is unclear. Comparable conclusions apply to PCC. PCC is recommended for the physiotherapy management of primary and secondary headache. Such recommendation remains however theoretical, not reaching clinical implementation. Yet, a shift from the traditional disease-centred model of care towards PCC is ongoing and should be continued in physiotherapy management. With this implementation, clinical and economical studies are needed to evaluate its effectiveness.

Purpose of review: To review existing literature on biomarkers for post-traumatic headache (PTH).

Recent findings: Preclinical models and clinical findings have started to elucidate the biology that underlies PTH. Traumatic brain injury results in ionic flux, glutamatergic surge, and activation of the trigeminal cervical complex resulting in the release of pain neuropeptides. These neuropeptides, including calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP), play a key role in the pathophysiology of migraine and other primary headache disorders. Only two studies were identified that evaluated CGRP levels in PTH. Neither study found a consistent relationship between CGRP levels and PTH. One study did discover that nerve growth factor (NGF) was elevated in subjects with PTH. There is no conclusive evidence for reliable blood-based biomarkers for PTH. Limitations in assays, collection technique, and time since injury must be taken into account. There are multiple ideal candidates that have yet to be explored.
