Current Pain and Headache Reports最新文献

Purpose of review: Complex Regional Pain Syndrome (CRPS) is a neuropathic pain disorder characterized by pain disproportionate to the inciting event that is constant for an extended duration. Numerous treatment options for this condition have been explored with unsatisfactory results in many cases. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist typically used as an anesthetic and analgesic, presents a promising potential treatment for CRPS in patients who fail to respond to traditional therapies.

Recent findings: Numerous studies report significant improvement in the degree of pain, mobility of extremities, and other parameters after ketamine infusion in patients with CRPS. Although adverse effects were not reported often, some subjects experienced nausea, vomiting, headache or psychotropic or psychomimetic symptoms which could be mitigated with cessation of the drug. Although more research is needed to determine optimal dosing and duration, ketamine seems to be a safe and effective treatment for refractory cases of CRPS.

Conclusion: The present investigation summarizes existing knowledge and research surrounding ketamine infusions for CRPS to provide a well-rounded depiction of advantages and disadvantages for physicians who may be considering it for patients with this challenging and complex condition.

Purpose of review: The purpose of this review is to describe the development and key features of the Prospera™ Spinal Cord Stimulation (SCS) System, as well as the clinical evidence supporting its use. Prospera delivers therapy using a proprietary multiphase stimulation paradigm and is the first SCS system to offer proactive care through automatic, objective, daily, remote device monitoring and remote programming capabilities.

Recent findings: Results from the recently published BENEFIT-02 trial support the short-term safety and efficacy of multiphase stimulation in patients with chronic pain. BENEFIT-03 is an ongoing, multicenter, single-arm study with 24-month follow-up; interim analyses suggest that multiphase therapy is safe and effective and that patients and clinicians have positive experiences with remote device management. Preliminary evidence suggests that the Prospera SCS System represents an opportunity to improve patient care by combining an effective multiphase stimulation paradigm with an efficient proactive care model.

Purpose of commentary: The number of facilities and physicians that offer pain management services has grown significantly since the 1970s. Despite the rise in prevalence of individuals with chronic pain during that time, interventional pain physicians remain underutilized. One reason why this may be the case is a large number of patients are referred directly to surgical specialists prior to being seen by an interventional pain physician. With the rising cost of healthcare, a shift away from surgical specialists and towards pain specialists as part of a multidisciplinary care team may help reduce the cost of care for chronic pain patients.

Recent findings: Through comparing the costs for patients with various types of chronic back pain, it was found that those who were treated by a pain physician rather than a surgeon saved up to over $8000 USD. Despite the cost benefits, it is important to recognize that healthcare disparities still exist which prevent patients from accessing interventional pain physicians. These disparities include patient location and insurance coverage. Overall, the treatment paradigm should start with non-invasive treatments, followed by minimally invasive procedures, with surgical interventions reserved as a last resort for when less invasive measures fail. Early incorporation of a multidisciplinary care team that includes chronic pain management services is critical for providing appropriate and cost-effective patient care.

Purpose of review: This review aims to understand the foundations of cognitive behavioral therapy (CBT) and biofeedback, their indications for therapy, and evidence-based support.

Recent findings: Both CBT and biofeedback are noninvasive therapy options for patients who are suffering from a variety of chronic pain conditions, including chronic low back pain, headache, fibromyalgia, and temporomandibular disorder (TMD). CBT has been shown to be effective in treating multiple chronic pain conditions.

Purpose of review: Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disorder predominantly affecting individuals of Mediterranean and Middle Eastern descent, including those with certain heritages including Sephardic Jewish, Armenian, Turkish, and Arab. The disorder affects up to 1 in 200 people making it a very common etiology for pain states worldwide, including serositis mediated painful states of the chest, joint, and abdomen.

Recent findings: Defined by recurrent episodes of fever and inflammation, FMF can lead to not only severe pain, but complications such as renal amyloidosis, if untreated. This narrative review explores the genetic basis, clinical manifestations, diagnostic criteria, and current management strategies for FMF. Mutations in the MEFV gene result in the dysregulation of the pyrin inflammasome, leading to excessive production of inflammatory cytokines. Diagnosis primarily relies on clinical criteria supported by genetic testing. Colchicine remains the cornerstone of treatment, effectively preventing inflammatory attacks and complications. For colchicine-resistant patients, IL-1 antagonists like anakinra and canakinumab show promise, although their long-term benefits require further investigation. The present investigation underscores the importance of early diagnosis and integrated treatment approaches to improve patient outcomes, pain management, and quality of life.

Purpose of review: The purpose of this review is to provide the most recent update and summary on the consideration, benefits and application of regional anesthesia in the ICU setting, as it pertains to the management of perioperative pain.

Recent findings: Regional anesthesia and analgesia have become ubiquitous in the perioperative setting, with numerous indications and benefits. As integral part of the multimodal analgesia approach, various regional blocks have been increasingly utilized in critically ill patients. We focus this review on various regional techniques employed for critically ill patients after cardiac, thoracic, and major abdominal surgery, including neuraxial and novel truncal blocks. Effective pain management in critically ill patients poses many challenges and is extremely important. Regional anesthesia, in combination with other analgesia modalities, while still under-utilized, can help reduce acute perioperative pain, stress response, opioid use and related side effects and expedite recovery and improve clinical outcomes.

Purpose of review: Post-laparoscopic shoulder pain (PLSP) can slow patient recovery and extend hospital stays, making its management crucial for patients undergoing laparoscopic surgery. Current consensus guidelines say little about how to prevent or manage PLSP. In this context, a multimodal approach to PLSP management that maybe extend beyond the pharmaceutical interventions currently employed. A variety of devices comprising both invasive and noninvasive approaches are available to patients, serving as adjuvants to analgesics. In this review, we explore the potential causes of PLSP. Additionally, by searching relevant databases and reviewing existing literature, we provide a comprehensive summary of current PLSP management strategies excluding analgesics.

Recent findings: A total of 30 articles were reviewed. The review identified a number of different treatments for PLSP, including trendelenburg position, discharge of residual gas, pulmonary recruitment manoeuvre, low-pressure pneumoperitoneum and phrenic nerve block, among others. However, the inconsistencies in the study designs resulted in disparate conclusions. While the current studies provide valuable insights, there is a clear need for further research in this area.

Purpose of review: The purpose of this review is to provide an update regarding recent research and recommendations in the care of mild traumatic brain injury (mTBI).

Recent findings: New diagnostic criteria for mTBI have recently been developed by the American Congress of Rehabilitation Medicine through the Delphi method and this will help to standardize assessment, diagnosis, and treatment. Symptoms of mTBI are diverse and can sometimes become persistent. Treatment of mTBI should be patient-centered and may require subspeciality referral and coordinated, inter-disciplinary, or multi-disciplinary treatment.

Management of acute and chronic pain following surgery remains a critical patient management challenge, with poor pain management associated with negative patient satisfaction, increased opioid consumption and a high incidence of adverse events. Chest surgery specifically carries a high incidence of significant early and chronic post operative pain. The high incidence, prolonged duration of pain, and adverse effects associated with chronic opioid analgesia, has given rise to the need for non-opioid pain management strategies. Cryoneurolysis, also known as cryoanalgesia, has emerged as a promising option for both acute and chronic pain management. While cryoneurolysis was first developed over fifty years ago, its utilization was limited by technical implementation challenges and limitations in identifying target structures percutaneously. Advances both in cryoneurolysis delivery devices as well as ultrasound have reinvigorated interest in the technique, with recent studies highlighting the advantages of cryoneurolysis, including its favorable side effect profile, long duration of efficacy and relative technical simplicity. The purpose of this review is to examine techniques for cryoneurolysis, and explore recent evidence for safety and efficacy of the technique following different surgical procedures.

Purpose of review: The objective of this review is to describe recent updates in the understanding of dialysis headache. These recent findings will be placed in a historical context that reviews the clinical features, classification, epidemiology, pathophysiology, and treatment of dialysis headache.

Recent findings: There is something intrinsic to the dialysis procedure itself that leads to headaches in susceptible individuals. Proposed mechanisms include fluid and electrolyte shifts, blood pressure parameters, the release of neuroinflammatory particles, and the mechanics of the dialysis procedure. Recent findings quantify the potential roles of CGRP and substance P in dialysis headache pathophysiology. Advances in dialysis techniques, like online hemodiafiltration, have also been found to vastly reduce headache incidence. Caffeine, which has anecdotally been considered potentially therapeutic for dialysis headache, may not actually provide benefit. Dialysis headache significantly impairs quality of life in many individuals on hemodialysis, a procedure which is itself already burdensome. A clearer understanding of the pathophysiology of dialysis headache has the potential to drive therapeutic advances.
