Integrative Approaches for Cancer Pain Management.

PURPOSE OF REVIEW: The goal of this review is to summarize updates to the broad array of complementary therapies available for cancer pain. This paper will serve as a reference for clinicians managing pain in cancer patients. RECENT FINDINGS: Patients are embracing integrative therapies in growing numbers; clinicians must be prepared to incorporate these therapies into patients' existing treatment regimens. This requires knowledge regarding risks, benefits, and potential interactions with existing cancer therapies. Integrative cancer pain management strategies have shown promise, with several proven effective for the management of cancer pain. Energy therapies, including acupuncture, and biologicals and nutraceuticals including overall diet and vitamin D, have the highest level of evidence for efficacy. The remaining therapies discussed in this chapter may be beneficial for patients on a case-by-case basis; risks and benefits of each individual therapy as described in the text must be further assessed in future rigorous trials to further clarify the role of these complementary therapies in cancer pain management.

The role of diet and non-pharmacologic supplements in the treatment of chronic neuropathic pain: A systematic review.

BACKGROUND/IMPORTANCE: Dietary interventions, vitamins, and nutritional supplementation are playing an increasingly important role in the management of neuropathic pain. Current pharmacological treatments are poorly tolerated and ineffective in many cases. OBJECTIVE: This systematic review aims to study the efficacy of dietary interventions, vitamins, and nutritional supplementation in the management of chronic neuropathic pain in adults. EVIDENCE REVIEW: The review followed PRISMA guidelines and was registered with PROSPERO (#CRD42022300312). Ten databases and gray literature, including Embase.com, MEDLINE and Web of Science, were systematically searched using a combination of keywords and controlled vocabulary related to chronic neuropathic pain and oral non-pharmacological supplements. Studies on adult humans published between 2000 and 2021 were considered for inclusion. The Cochrane Handbook was used to assess risk of bias, and Grading of Recommendations Assessment, Development, and Evaluation was used to determine overall quality of evidence. FINDINGS: Forty studies were included in the final review, and results were categorized according to pain type including pain related to chemotherapy-induced peripheral neuropathy (CIPN, 22 studies, including 3 prospective cohorts), diabetic peripheral neuropathy (DPN, 13 studies, including 2 prospective), complex regional pain syndrome (CRPS-I, 3 studies, including 1 prospective), and other (2 studies, both RCT). The CIPN studies used various interventions including goshajinkigan (4 studies), vitamin E (5), vitamin B12 (3), glutamine (3), N-acetyl-cysteine (2), acetyl-l-carnitine (2), guilongtonluofang (1), ninjin'yoeito (1), alpha-lipoic acid (1), l-carnosine (1), magnesium and calcium (1), crocin (1), and antioxidants (1), with some studies involving multiple interventions. All CIPN studies involved varying cancers and/or chemotherapies, advising caution for generalizability of results. Interventions for DPN included alpha-lipoic acid (5 studies), vitamin B12 (3), acetyl-l-carnitine (3), vitamin E (1), vitamin D (2), and a low-fat plant-based diet (1). Vitamin C was studied to treat CRPS-I (3 studies, including 1 prospective). Magnesium (1) and St. John's wort (1) were studied for other or mixed neuropathologies. CONCLUSIONS: Based on the review, we cannot recommend any supplement use for the management of CIPN, although further research into N-acetyl-cysteine, l-carnosine, crocin, and magnesium is warranted. Acetyl-l-carnitine was found to be likely ineffective or harmful. Alpha-lipoic acid was not found effective. Studies with goshajinkigan, vitamin B12, vitamin E, and glutamine had conflicting results regarding efficacy, with one goshajinkigan study finding it harmful. Guilongtonluofang, ninjin'yoeito, and antioxidants showed various degrees of potential effectiveness. Regarding DPN, our review supports the use of alpha-lipoic acid, acetyl-l-carnitine, and vitamin D. The early use of vitamin C prophylaxis for the development of CRPS-I also seems promising. Further research is warranted to confirm these findings.

Pain management in hidradenitis suppurativa and a proposed treatment algorithm.

Pain contributes substantially to reduced quality of life in individuals living with hidradenitis suppurativa (HS). Although improved understanding of HS pathogenesis and treatment has resulted in improved evidence-based HS management guidelines, comprehensive pain management guidelines have yet to be developed. Few HS-specific data exist to guide pharmacologic analgesia; however, recognizing HS pain as either acute or chronic and predominantly nociceptive (aching and gnawing pain due to tissue damage) versus neuropathic (burning-type pain due to somatosensory nervous system dysfunction) provides a conceptual framework for applying outside pain management practices to HS management. This article incorporates the best available evidence from the HS and pain literature to propose an HS pain algorithm that integrates psychological, pharmacologic, and complementary and alternative treatment modalities.

Techniques for Peripheral Nerve Stimulator Implantation of the Upper Extremity.

OBJECTIVE: To present a technical note on how to perform upper extremity peripheral nerve stimulators for three major nerves: median, ulnar, and radial. DESIGN: Literature review and expert opinion. SETTING: Single academic center. RESULTS: Peripheral nerve stimulation has recently become popular with the development and availability of peripheral nerve stimulators with an external pulse generator. Here, we describe ultrasound anatomy and technical details for peripheral nerve stimulation in the upper extremity for three major nerves: median, ulnar, and radial. CONCLUSIONS: Upper extremity peripheral nerve stimulation can be considered as an option for refractory neuropathic upper extremity pain.

BIOTIN INTERFERENCE WITH ROUTINE CLINICAL IMMUNOASSAYS: UNDERSTAND THE CAUSES AND MITIGATE THE RISKS.

OBJECTIVE: The objectives of this report are to review the mechanisms of biotin interference with streptavidin/biotin-based immunoassays, identify automated immunoassay systems vulnerable to biotin interference, describe how to estimate and minimize the risk of biotin interference in vulnerable assays, and review the literature pertaining to biotin interference in endocrine function tests. METHODS: The data in the manufacturer's "Instructions for Use" for each of the methods utilized by seven immunoassay system were evaluated. We also conducted a systematic search of PubMed/MEDLINE for articles containing terms associated with biotin interference. Available original reports and case series were reviewed. Abstracts from recent scientific meetings were also identified and reviewed. RESULTS: The recent, marked, increase in the use of over-the-counter, high-dose biotin supplements has been accompanied by a steady increase in the number of reports of analytical interference by exogenous biotin in the immunoassays used to evaluate endocrine function. Since immunoassay methods of similar design are also used for the diagnosis and management of anemia, malignancies, autoimmune and infectious diseases, cardiac damage, etc., biotin-related analytical interference is a problem that touches every area of internal medicine. CONCLUSION: It is important for healthcare personnel to become more aware of immunoassay methods that are vulnerable to biotin interference and to consider biotin supplements as potential sources of falsely increased or decreased test results, especially in cases where a lab result does not correlate with the clinical scenario.

Co-Infection of Dengue in a Pregnant Woman With COVID-19 Disease.

The pandemic due to severe respiratory syndrome coronavirus 2 (SARS-Cov-2) was one of the most damaging healthcare emergencies the world has ever seen. Co-infection with dengue virus in COVID-19-positive patients is an additional challenge especially in dengue-endemic areas. Both dengue and COVID-19 infection cause increased morbidity and adverse outcomes in pregnant women, and simultaneous infection of these two illnesses can be further detrimental and sometimes fatal in pregnant women. Here, we present a case of a pregnant woman in her early second trimester with co-infection of dengue and moderate COVID-19 disease who was managed successfully and had a favorable outcome.

Comparison of the Efficacies of Dexmedetomidine and Clonidine in Preventing Postoperative Nausea and Vomiting in Paediatric Patients Undergoing Abdominal Surgeries.

Background Postoperative nausea and vomiting (PONV) is a common complication in paediatric patients undergoing abdominal surgeries. Dexmedetomidine and clonidine, both α2-adrenergic agonists, have been proposed as potential treatments for PONV due to their antiemetic properties. This study aimed to compare the efficacies of dexmedetomidine and clonidine in the prevention of PONV in paediatric patients following abdominal surgeries Methods Eighty patients, aged five to 12 years undergoing abdominal surgeries under general anaesthesia were enrolled in this study. Patients were randomly assigned to receive either a single intravenous dose of 0.5 µg/kg of dexmedetomidine (Group D; n=40) or 1 µg/kg of clonidine (Group C; n = 40) 10 minutes before extubation. PONV was recorded for the next 24 hours. Results The baseline characteristics of patients were comparable. A higher proportion of patients in the clonidine group developed PONV as compared to the dexmedetomidine group (27.5% vs 20.0%, p=0.189). The visual analogue scale (VAS) score of group C was higher than that of group D (1.38±1.55 vs 1.00±1.26) but was not statistically significant. The Paediatric Anaesthesia Emergence Delirium (PAED) scale score or emergence agitation (EA) score was higher in group C during recovery time. The mean arterial pressures and the heart rates were comparable in both groups. No significant side effects were reported. Conclusion Our study concludes that dexmedetomidine and clonidine effectively control PONV in paediatric abdominal surgery, with no significant difference in incidence or severity. Dexmedetomidine significantly reduced PAED scale scores during recovery, indicating better control of EA. The two treatments showed comparable mean arterial pressures and heart rates without significant side effects.

Role of prophylactic tranexamic acid in reducing blood loss during cesarean section: A double-blind placebo-controlled randomized controlled trial.

Background: Postpartum hemorrhage (PPH) is defined by the World Health Organization as blood loss of ≥500 mL within 24 h of delivery. Globally, hemorrhage accounts for 27.1% of maternal deaths, making it the leading direct cause of maternal death. PPH has been identified in more than two-thirds of reported hemorrhage-related deaths, causing 38% of maternal deaths in India. Tranexamic acid, an antifibrinolytic, has been used to control bleeding after PPH is identified. Materials and Methods: Antenatal women admitted for elective cesarean section were randomized into two arms: the case group (received one gram of tranexamic acid 20 min prior to skin incision) and the control group (received a placebo), each group consisting of 36 participants. Clinical Trials Registry - India (CTRI) registration number - CTRI/2021/02/031579. Results: The mean (±standard deviation [SD]) intraoperative blood loss in the case group was 241.25 (±67.83) mL, and in the control group, it was 344.92 (±146.67) mL (P = 0.001), while postoperative blood loss did not differ significantly between the groups (P = 0.1470). In terms of the difference in hemoglobin, there was a significant difference between the two groups (P = 0.001). No significant maternal or neonatal side effects were found. Conclusion: Preoperative tranexamic acid, when given in elective cesarean section, significantly reduces intraoperative blood loss.

Study of the Vertical Transmission of COVID-19 by Using the World Health Organisation Protocol in a Tertiary Care Hospital in Eastern India.

BACKGROUND: The World Health Organisation (WHO) has established criteria to diagnose vertical transmission in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to determine the incidence of vertical transmission of SARS-CoV-2 using WHO criteria in a tertiary care centre in eastern India. METHODS: A hospital-based prospective observational study was conducted from June 2021 to February 2022 on women admitted for delivery with a positive nasopharyngeal (NP) swab and a SARS-CoV-2 real-time reverse-transcriptase polymerase chain reaction (RT-PCR) test. Following the delivery, the amniotic fluid (AF) and swab from the placenta were tested for SARS-CoV-2 by the Truenat test. The umbilical cord and maternal blood were analyzed to detect immunoglobulin M (IgM) and immunoglobulin G (IgG). The nasopharyngeal swabs of the newborns were tested for SARS-CoV-2 by RT-PCR. RESULTS: Forty-eight SARS-CoV-2-positive asymptomatic women were included in the study. Twenty-eight (58.3%) were delivered via cesarean section. Preterm delivery occurred in 13 (27.1%) cases. In only one case, vertical transmission was confirmed as the neonate had a positive nasopharyngeal SARS-CoV-2 RT-PCR test and the cord blood was IgM positive (suggesting an immune response in the neonate). The placenta was positive in three cases, and amniotic fluid was positive in two. However, vertical transmission was deemed unlikely in these cases as there was no evidence of immune response or viral persistence according to the WHO criteria. There was one stillbirth, and it tested negative for SARS-CoV-2. CONCLUSION: This study strengthens the evidence of vertical transmission in COVID-19-positive asymptomatic mothers. The data suggest a low transmission rate.

Comparative Study of Pregnancy Outcomes in Women With COVID-19 Disease During the Three Waves of the Pandemic in Eastern India.

Introduction Healthcare systems around the world were disrupted by the COVID-19 pandemic. Multiple waves were experienced by most countries, and clinical symptoms and severity varied between these waves. A COVID-19 infection in pregnant women may result in complications for both the mother and the fetus and thus pose an additional challenge for clinicians. The study of the different presentations, complications, and pregnancy outcomes during the three waves is important to study the effect of the disease on pregnant women. Objective This study aimed to analyze and compare the clinical presentations, comorbid conditions, complications, and pregnancy outcomes in women with SARS-CoV-2 infection during the three waves of the pandemic. Methodology The present study is a comparative study undertaken at Tata Main Hospital, a referral hospital in Jamshedpur in eastern India. The study period was from May 2020 to February 2022 and was divided according to the three waves of the pandemic. The duration of the first wave was between 1st May 2020 and 28th February 2021; the second wave was between 1st March 2021 and 31st October 2021; and the third wave was between 1st November 2021 and 28th February 2022. A total of 306 pregnant women tested positive for COVID-19 disease during the study period. A retrospective collection of data was done, and clinical findings, laboratory results, comorbid conditions, and outcomes were compared across the three waves. Results During the first wave of the pandemic, 139 COVID-19-positive pregnant women were admitted to our hospital. During the second wave, 110 admitted pregnant women tested positive for SARS-CoV-2 infection, and during the third wave, 57 pregnant women tested positive for SARS-CoV-2 infection. Asymptomatic or mild disease was the most commonly seen presentation during all the waves, but a significantly higher number of moderate and severe cases were seen during the second wave. The second wave also witnessed a higher rate of cesarean sections when compared to the other two waves. The preterm delivery rate was 27.8%, 24.7%, and 25% during the first, second, and third waves of the pandemic, respectively. The third wave of the pandemic had the highest percentage of stillbirths, which was significantly higher than both the first and second waves. The COVID-19 test was positive in four babies during the study period. Conclusion The severity of COVID-19 disease varied among the three waves, and the second wave recorded the maximum number of moderate and severe cases. Maternal mortality was also significantly higher during the second wave. The rate of preterm deliveries was high during all the waves, and the incidence of stillbirths was highest during the third wave.

MR-conditionality failure modes: a comparison across various spinal cord stimulators.

As spinal cord stimulation (SCS) becomes a staple of chronic pain management, the SCS industry must constantly evolve to ensure safety, convenience and enhanced efficacy. Beyond waveforms and size, MR-conditionality is a key differentiator sought out by physicians and patients when choosing SCS devices. Many common SCS complications, including lead migration, can affect the MR-conditionality. The authors reviewed literature published between 2015 and 2024 using PubMed and Google Scholar databases, as well as US FDA labels for magnetic resonance imaging and technical manuals with further confirmation from local representatives. Through extensive review of the literature and direct extraction from each SCS device company, the authors aimed to investigate the specific terms of MR-conditionality under various circumstances. This article provides a collective reference of the MR-conditionality of the currently available SCS devices under normal conditions, as well as with common failure modes, such as lead migration, lead fracture and battery detachment.

This is a narrative review of intravenous ketamine infusions for the treatment of complex regional pain syndrome (CRPS). It briefly covers the definition of CRPS, its epidemiology, and other treatments before introducing ketamine as the article's focus. A summary of ketamine's evidence base and its mechanisms of action is provided. The authors then review ketamine dosages reported in peer-reviewed literature for the treatment of CRPS, and their associated duration of pain relief. The observed response rates to ketamine and predictors of treatment response are also discussed.

Racial and Ethnic Disparities in Inpatient Interventional Pain Management for Lumbar Radiculopathy.

BACKGROUND: Chronic pain is a common reason adults seek care; patients often feel that their pain is inadequately managed. Spine-related pain is the most common chronic pain concern, and lumbar radiculopathy is often the cause. Racial and ethnic disparities in the pharmacologic management of pain are well described, but less is known about these disparities regarding interventional procedures. OBJECTIVE: To study the utilization rates of physical therapy, epidural steroid injection, surgery, and spinal cord stimulation in hospitalized patients with lumbar radiculopathy across different races, ethnicities, and genders. STUDY DESIGN: A retrospective cross-sectional study design. METHODS: The National Inpatient Sample was used to identify 252,790 patients with lumbar radiculopathy, after sample weighting, from 2016-2019. Independent variables were race, ethnicity, age, gender, insurance, geography, year, and severity. Dependent variables were physical therapy, epidural steroid injection, spinal cord stimulator, or surgery (reference group). Conservative management was defined as nonoperative treatment ranging from physical therapy to epidural steroid injection. Data were analyzed with a logistic regression for complex surveys. Regressions were adjusted for age, insurance, geography, and other socioeconomic factors. RESULTS: Most patients were white (78.3%) and received surgery (95.0%). Severe disease was most common among African Americans (9.3%), but was similar across other races, ethnicities, and genders. Medicaid was more common among African Americans and Hispanics. An adjusted analysis showed that African Americans and Hispanics received more epidural steroid injections (odds ratio [OR] = 1.52; 95%CI, 1.3 - 1.8) and (OR = 1.43; 95%CI, 1.1 - 1.8) respectively; and physical therapy (OR = 1.65; 95%CI, 1.1 - 2.5) and (OR = 1.83; 95%CI, 1.2 - 2.8) respectively, than whites compared to surgery. African Americans received a spinal cord stimulator less often than whites compared to surgery (OR = 0.63; 95%CI. 0.4 - 0.9). Women received an epidural steroid injection more frequently than men compared to surgery (OR = 1.29; 95%CI, 1.2 - 1.4). LIMITATIONS: Generalizability is limited because conservative therapies are often outpatient treatments. CONCLUSION: Disparities were observed in lumbar radiculopathy treatment after independent variable adjustment. African Americans received conservative therapy more often than whites despite increased disease severity. Hispanics and women had similar disease severity compared to whites and men, respectively, but received more conservative therapies. Further investigation in outpatient settings is needed to definitively describe these disparities. KEY WORDS: Chronic pain, pain management, back pain, lumbar radiculopathy, epidural steroid injection, spinal cord stimulation, low back surgery, physical therapy, racial disparities, gender disparities.

Missing Cells-A Rare Case of Persisting Thrombocytopenia in Pregnancy With Dengue and Role of Romiplostim in These Cases.

Objective: Dengue cases in pregnancy have high morbidity and mortality. More so if it leads to immune thrombocytopenic purpura which causes a drastic decrease in platelet, increasing chances of bleeding and mortality and pregnancy itself being a state of hemodynamic instability. Case report: Here, we present a case of dengue causing secondary immune thrombocytopenia. Managing these cases is challenging and need a multidisciplinary approach and should be done at a higher center. In previous reports, thrombocytopenia in such cases responded to steroids or IVIG. But in our case patient did not respond to either of them but to Romiplostim. There are only a few studies on the use of Romiplostim in dengue and dengue induced ITP and more study is required. Conclusion: Dengue induced persistent thrombocytopenia is rare but should always be kept in mind in managing these cases.

Relationship Between Pre- and Post-Operative C-Reactive Protein (CRP), Neutrophil-to-Lymphocyte Ratio (NLR), and Platelet-to-Lymphocyte Ratio (PLR) With Post-Operative Pain After Total Hip and Knee Arthroplasty: An Observational Study.

BACKGROUND: Anesthetic technique and postoperative pain management are crucial for total joint arthroplasty (TJA) patients. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP) are new, simple, and cost-effective predictors for prognosis. The predictive value of NLR as an inflammatory marker can predict post-operative pain caused by inflammatory pathways secondary to surgical trauma. CRP is also the most sensitive and specific biomarker of inflammation whereas PLR was also recently considered a possible marker for inflammation which may further contribute to pain and sequelae. Thus, anesthetists can make decisions about the amount, time, and type of analgesic to use based on preoperative values of these parameters to provide maximum postoperative pain control and facilitate early rehabilitation. Thus, the current study was conducted to determine the relationship between CRP, NLR, and PLR levels and the intensity of pain in patients following total hip arthroplasty (THA) and total knee arthroplasty (TKA). MATERIALS AND METHODS: A total of 105 patients scheduled for THA and TKA fulfilling the study's inclusion criteria were enrolled. Inclusion criteria of the study were all the patients giving written consent, ASA Grade I-III, patients between 18 and 90 years who were scheduled for elective lower extremity TJA, and all the patients who remained admitted until stitches were removed. Patients were given intrathecal 15 mg hyperbaric bupivacaine via 25G atraumatic spinal needle in the L3-L4 interspace. The recorded data were demographic characteristics, preexisting comorbidities, number of blood transfusions, and operation time, postoperative analgesics given, duration of hospital stay, time of mobility, pain scoring as per visual analog scale (VAS) scoring system with an aim to establish a relationship between pre- and post-operative (Days 3 & 5) CRP, NLR, and PLR with post-operative pain after THA and TKA. RESULT: The present study demonstrated a significant correlation (p < 0.002) between preoperative and postoperative NLR with pain after TJA whereas PLR and CRP did not show any significant relationship with post-operative pain after THA and TKA. A significantly higher NLR ratio was observed for patients on all the periods of observation (pre-op., Day 3, and Day 5). Pre-op. and Day 5 NLR of patients who required transfusion were significantly higher than those who did not require transfusion and patients with higher NLR values could be mobilized significantly later and had significantly higher duration of hospital stay. The correlation of CRP levels and PLR levels at different time intervals did not show a significant correlation with Day 3 and Day 5 pain scores. CONCLUSION: The present study demonstrated a significant correlation between preoperative and postoperative NLR with pain after TJA.

Awareness, knowledge, and psycho-emotional aspect of infertility among women seeking fertility assistance at a tertiary care hospital in Chhattisgarh, a cross-sectional study.

BACKGROUND: The lack of fundamental knowledge and awareness about the biological process of reproduction is low worldwide but has reportedly higher incidence rates in under-developed countries. Infertility can have a tremendous effect on a woman's psychological and social well-being, pushing her toward mental stress, anxiety, depression self-blame, self-isolation, feeling of worthlessness, and lack of interest in life. The present study was conducted to determine the level of knowledge and awareness regarding factors affecting fertility and also to ascertain the emotional status of females visiting the Obstetrics and Gynecology out-patient department for fertility assistance. MATERIALS AND METHODS: A cross-sectional study was performed by using a questionnaire which had two parts; the first part had questions about awareness and knowledge of the subject of infertility, and the second part had 12 questions that assessed the psychological and emotional status of the participants, and it also explored prevailing myths about infertility based on a validated questionnaire. RESULTS: There was a significant difference in mean knowledge score; those who were more educated had better knowledge of various aspects of infertility. The overall adequacy for knowledge and awareness revealed that only 62 (47.7%) of the participants had adequate knowledge (score >6) regarding female infertility. The mean score for knowledge among all the respondents was 6.61 ± 1.48. The overall emotional and psychological score suggested that 30 (23%) of the respondents were disturbed because of stress because of infertility. CONCLUSION: Infertility can have a serious impact on the psychological well-being of females, and social pressure and stigma associated with childlessness can further worsen the physical and emotional well-being of couples, which needs to be addressed before starting treatment of infertility for a better response to treatment. The limited knowledge and prevailing mis-conceptions regarding infertility need to be sincerely dealt with to complement the medical treatment of infertility.

Low-Dose Naltrexone (LDN) for Chronic Pain at a Single Institution: A Case Series.

Purpose: Low-dose naltrexone (LDN) has increased in popularity as a non-opioid medication that may decrease chronic pain symptoms. LDN is most commonly used to treat fibromyalgia, complex regional pain syndrome (CRPS), and painful diabetic neuropathy. Other studies suggest that LDN provides general symptom reduction in inflammatory conditions such as Crohn's disease and multiple sclerosis. We reviewed our experience with patients to whom we have prescribed LDN to see what types of painful conditions were most responsive to LDN in our patient population. Patients and Methods: Charts from patients who came to the Pain Center between 2014 and 2021 were reviewed. Results: Of the n = 137 patients who were prescribed LDN, 44% had no evidence of ever filling the prescription, and 4.4% of the responses were not charted. Of the remaining who took LDN (n = 70), 64% had some relief and were designated as 'Responders'. The most common pain diagnosis was neuropathic pain which, when added to the diagnosis of complex regional pain syndrome, accounted for 51% of responders to LDN. Patients who experienced greater than 50% pain relief from LDN were more likely to have the diagnosis of neuropathic pain or complex regional pain syndrome (p = 0.038, Fisher's Exact Test). There was a significant difference in the diagnosis of patients who responded to LDN. Patients with spondylosis were much less likely to respond to LDN when compared with other diagnoses (p = 0.00435, Chi-Square Test). Conclusion: Patients with all types of neuropathic pain, including CRPS, were significantly more likely to have pain relief from LDN than patients with spondylosis (p=0.018). The diagnosis of spondylosis was more often associated with a lack of response to LDN than any other diagnosis. Patients may need to have a trial of several weeks before analgesic effects are seen with LDN.

Pain Education and Knowledge (PEAK) Consensus Guidelines for Neuromodulation: A Proposal for Standardization in Fellowship and Training Programs.

The need to be competent in neuromodulation is and should be a prerequisite prior to completing a fellowship in interventional pain medicine. Unfortunately, many programs lack acceptable candidates for these advanced therapies, and fellows may not receive adequate exposure to neuromodulation procedures. The American Society of Pain and Neuroscience (ASPN) desires to create a consensus of experts to set a minimum standard of competence for neurostimulation procedures, including spinal cord stimulation (SCS), dorsal root ganglion stimulation (DRG-S), and peripheral nerve stimulation (PNS). The executive board of ASPN accepted nominations for colleagues with excellence in the subject matter of neuromodulation and physician education. This diverse group used peer-reviewed literature and, based on grading of evidence and expert opinion, developed critical consensus guides for training that all accredited fellowship programs should adopt. For each consensus point, transparency and recusal were used to eliminate bias, and an author was nominated for evidence grading oversight and bias control. Pain Education and Knowledge (PEAK) Consensus Guidelines for Neuromodulation sets a standard for neuromodulation training in pain fellowship training programs. The consensus panel has determined several recommendations to improve care in the United States for patients undergoing neuromodulation. As neuromodulation training in the United States has evolved dramatically, these therapies have become ubiquitous in pain medicine. Unfortunately, fellowship programs and the Accreditation Council for Graduate Medical Education (ACGME) pain program requirements have not progressed training to match the demands of modern advancements. PEAK sets a new standard for fellowship training and presents thirteen practice areas vital for physician competence in neuromodulation.
