RESUMO

Fibromyalgia (FM) presents a diagnostic challenge due to its complex symptoms and lack of definitive tests. This study discusses a 54-year-old female initially diagnosed with FM, characterized by widespread pain, fatigue, and tender points. Despite treatment, she developed elevated C-reactive protein (CRP) and anemia after two years, leading to further investigations. These tests revealed non-secretory multiple myeloma, underscoring the importance of vigilant monitoring in FM patients. This case highlights the need for regular CRP measurements and thorough follow-up to detect underlying conditions. Early detection and appropriate intervention are crucial in managing FM and improving patient outcomes.

RESUMO

Background Pain after breast surgery has been described as moderate to severe in intensity and, if inadequately treated, increases postoperative morbidity, hospital cost, and the incidence of persistent postoperative pain. Serratus anterior plane (SAP) block is an interfascial injection technique for analgesia of the chest wall. There is a lack of data with regard to its analgesic and possible opioid-sparing effects in Sub-Saharan Africa. This study aimed to determine the perioperative analgesic effect of serratus anterior plane block administered for breast surgery. Methods This was a prospective, randomized, double-blinded study involving 52 patients and was randomized into the intervention (n = 26) and control (n = 26) groups. One patient in the control group did not receive the allocated intervention, while one in the intervention group lost to follow-up. Complete data of 50 participants, comprising intervention (n=25), was used in the analysis. Patients' demographic and health characteristics, pre-induction, intra-operative, and postoperative hemodynamic parameters were noted. After induction of anesthesia, a blinded anesthetist performed an ultrasound-guided serratus anterior plane block with 0.25% plain bupivacaine or a sham block using 0.9% normal saline (control). Numerical rating scale (NRS) score and incidence of postoperative nausea and vomiting (PONV) were recorded immediately after surgery and at 1, 4, 8, and 24 postoperative hours. Patient satisfaction with analgesic management within the first 24 postoperative hours was also assessed. Results Patients who received SAP block had lower NRS scores at all measured time points, but this was only statistically significant at the fourth postoperative hour (p-value = 0.002). Compared to controls, patients who received SAP had lower intraoperative (11.3±1.5 mg vs. 11.9±1.5 mg, p value = 0.131) and postoperative (4.6±5.7mg vs. 10.5±6 mg, p value=0.001) mean opioid consumption. However, only the reduction in postoperative opioid consumption was found to be statistically significant. Most participants (> 90%) in this study did not experience PONV and were very satisfied with their postoperative pain management. Conclusion Serratus anterior plane block reduces NRS pain scores postoperatively. It also significantly reduces postoperative opioid consumption but does not significantly reduce intraoperative opioid consumption.

RESUMO

Lameness and restricted mobility are a significant concern in companion animals experiencing chronic pain, inflammation, or age-related pathologies. The growing awareness of health risks and side effects associated with the long-term use of prescription analgesics requires different management strategies to address these issues. In this study, we conducted a crossover evaluation of the effect of full spectrum hemp oil dosed orally at 2 mg/kg BID phytocannabinoids for 8 weeks in dogs (n = 37) living with pain in common household settings. Owner-reported canine pain, home activity, accelerometer-based activity, walkway-based gait, and tolerability were assessed at each phase of the study. Secondary endpoints included changes in blood biochemistry, liver enzymes, inflammatory biomarkers, and plasma metabolites. The intervention was positively associated with a decrease in pain scores (-46.2%, p = 0.0016), increased ability to walk up and down the stairs (10.6-14.7%, p < 0.05), and improved daily activity (25.9%, p = 0.0038). Decreases in plasma levels of proinflammatory cytokines TNF-α, IL-6, and IL-8 were also observed. Taken together, these findings suggest that the benefits of nutritional supplementation with hemp oil could include control of pain, greater mobility, and an overall improvement in the animal wellbeing.

RESUMO

BACKGROUND: Older head and neck cancer (HNC) survivors have concerning rates of potentially unsafe opioid prescribing. Identifying the specialties of opioid prescribers for HNC survivors is critical for targeting the settings for opioid safety interventions. This study hypothesized that oncology and surgery providers are primarily responsible for opioid prescriptions in the year after treatment but that primary care providers (PCPs) are increasingly involved in prescribing over time. METHODS: Using linked Surveillance, Epidemiology, and End Results-Medicare data, a retrospective analysis was conducted of adults aged >65 years diagnosed between 2014 and 2017 with stage I-III HNC and who had ≥6 months of treatment-free follow-up through 2019. Starting at treatment completion, opioid fills were assigned to a prescriber specialty: oncology, surgery, primary care, pain management, or other. Prescriber patterns were summarized for each year of follow-up. Multinomial logistic regression models captured the likelihood of opioids being prescribed by each specialty. RESULTS: Among 5135 HNC survivors, 2547 (50%) had ≥1 opioid fill (median, 2.1-year follow-up). PCPs prescribed 47% of all fills (42%-55% each year). PCPs prescribed opioids to 45% of survivors with ≥1 opioid fill, which was a greater share than other specialties. PCPs prescribed longer supplies of opioids (median, 20 days/fill; median, 30 days/year) than oncologists or surgeons. The likelihood of an opioid being prescribed by an oncology provider was four times lower than that of it being prescribed by a PCP. CONCLUSIONS: PCP involvement in opioid prescribing remains high throughout HNC survivorship. Interventions to improve the safety of opioid prescribing should target primary care, as is typical for opioid reduction efforts in the noncancer population.

RESUMO

BACKGROUND: There is a knowledge-to-practice gap regarding parent-delivered pain management, and few studies have investigated parents' and nurses' participation in and acceptance of combined parent-delivered pain-alleviating interventions such as skin-to-skin contact (SSC), breastfeeding, and parental musical presence. This study investigated parents' and nurses' perceptions of and reflections on experiencing combined parent-delivered pain management. METHODS: This qualitative study applies a collaborative participatory action research design using ethnographic data collection methods such as focus groups, video observations, and video-stimulated recall interviews with parents and nurses. RESULTS: The results concern three main categories, i.e., preparation, participation, and closeness, as well as various sub-categories. Preparations were central to enabling combined parent-delivered pain management. Participation was facilitated by parental musical presence, in which parents shifted their attention toward their infant. Closeness and presence during neonatal care helped parents become active during their infant's painful procedures. Parental lullaby singing created a calm and trusting atmosphere and after the procedure, both parents and nurses felt that they had successfully supported the infant through a potentially painful procedure. CONCLUSIONS: Mental and practical preparation is central to implementing combined parent-delivered pain management. When parents and nurses explored the interventions, they found the methods feasible, promoting self-efficacy and confidence in both parents and nurses.

RESUMO

INTRODUCTION: Patients living with substance use disorder (SUD) have complex pain management needs, which may be mismanaged during hospital admission. Ineffectively managed pain following orthopaedic trauma, influenced by clinician biases related to race or SUD diagnosis, may subject patients to worse pain outcomes and subsequent emergency department (ED) encounters. This study examined ED encounters and opioid prescribing for pain-related complaints following orthopaedic trauma, among patients with SUD who identify as Black or African American relative to White patients. METHODS: This retrospective analysis included 1089 patients with a SUD diagnosis discharged from a Level I trauma center, following hospitalization for orthopaedic injuries, between 2016 and 2021. Multivariable regressions assessed the associations among race, opioid prescribing, and ED encounters within 90 days for pain-related care. RESULTS: Among the 1089 patients included in the sample, the proportion of individuals with an ED encounter within 90 days for pain-related care was 12.4 % and 4.5 % for Black and White patients, respectively (odds ratio [OR] = 3.0, p < .001). When adjusting for injury severity and demographics, the difference in ED encounters between Black and White patients remained significant (OR = 2.8, p = .002). Opioid prescription doses did not statistically differ by race. CONCLUSIONS: The difference in ED encounters between Black and White patients with SUDs following orthopaedic trauma may indicate a need to optimize pain management prior to initial discharge and improve post-injury care.

RESUMO

INTRODUCTION: Low back pain (LBP) is the leading global cause of disability. Patients with moderate to severe LBP who respond positively to a diagnostic medial nerve branch block can be offered radiofrequency denervation (RFD). However, high-quality evidence on the effectiveness of RFD is lacking. METHODS AND ANALYSIS: RADICAL (RADIofrequenCy denervAtion for Low back pain) is a double-blind, parallel-group, superiority randomised controlled trial. A total of 250 adults listed for RFD will be recruited from approximately 20 National Health Service (NHS) pain and spinal clinics. Recruitment processes will be optimised through qualitative research during a 12-month internal pilot phase. Participants will be randomised in theatre using a 1:1 allocation ratio to RFD or placebo. RFD technique will follow best practice guidelines developed for the trial. Placebo RFD will follow the same protocol, but the electrode tip temperature will not be raised. Participants who do not experience a clinically meaningful improvement in pain 3 months after randomisation will be offered the alternative intervention to the one provided at the outset without disclosing the original allocation. The primary clinical outcome will be pain severity, measured using a pain Numeric Rating Scale, at 3 months after randomisation. Secondary outcomes will be assessed up to 2 years after randomisation and include disability, health-related quality of life, psychological distress, time to pain recovery, satisfaction, adverse events, work outcomes and healthcare utilisation. The primary statistical analyses will be by intention to treat and will follow a prespecified analysis plan. The primary economic evaluation will take an NHS and social services perspective and estimate the discounted cost per quality-adjusted life-year and incremental net benefit of RFD over the 2-year follow-up period. ETHICS AND DISSEMINATION: Ethics approval was obtained from the London-Fulham Research Ethics Committee (21/LO/0471). Results will be disseminated in open-access publications and plain language summaries. TRIAL REGISTRATION NUMBER: ISRCTN16473239.

RESUMO

BACKGROUND: Femoral nerve block (FNB) is a prevalent method used for postoperative pain management after knee surgery; however, it decreases the strength of the quadriceps muscle and is not conducive to early recovery after surgery. Pectineus muscle plane (PMP) block involves the injection of a local anaesthetic into the fascial plane below the pectineus muscle, where it blocks the obturator and saphenous nerves. However, there is little evidence on the effectiveness of PMP block for analgesia after knee surgery. The aim of this trial is to assess whether PMP block can improve postoperative analgesia, promote early recovery and reduce the length of hospital stay. METHODS AND ANALYSIS: In this randomised controlled study, 46 patients will be randomly allocated into two groups: the PMP block group (n=23) and the FNB group (n=23). The primary outcome measures will include Visual Analog Scale scores for pain at rest and during movement at various time points following knee surgery. Secondary outcomes will include the degree of active flexion, straight leg raise test performance, get-out-of-bed test result, 20 m walk test result, total dose administered via patient-controlled analgesia infusion pumps, hospital stay duration, patient satisfaction and postoperative complications, such as pulmonary embolism and deep vein thrombosis.This study protocol adheres to rigorous standards for ethical conduct and patient safety. The findings from this trial are expected to contribute valuable insights to the optimisation of postoperative pain management strategies and the improvement of early recovery outcomes for patients who undergo knee surgery. ETHICS AND DISSEMINATION: This trial has been approved by the ethics committee of Zhejiang Hospital (2022(128K)) on 17 November 2022, and inpatients who meet the inclusion criteria and diagnostic requirements are eligible for this study. Any subsequent protocol and informed consent document amendments must be approved by the responsible ethics committee. All communications with the regulatory authorities and the ethics committee must be recorded. All recruited patients will be informed of the trial purposes and their duties within the trial before randomisation. Recruited patients can withdraw from the study at any time without providing any specific reason. The patient data will be stored in a separate, safe place, but that it may be reviewed by the relevant investigator. The results will be published in international peer-reviewed medical journals.

RESUMO

Background: External oblique intercostal block (EOIB) is effective in relieving pain in the T6 to T10 dermatomes; however, there is limited evidence comparing EOIB with conventional regional anesthesia. In this randomized controlled trial, it was hypothesized that EOIB would provide more effective analgesia than wound infiltration (WI) in laparoscopic gastrectomy. Methods: Thirty-two patients (aged 20-85 years) with American Society of Anesthesiologists Performance Status of 1 to 2, scheduled for laparoscopic gastrectomy, were randomly divided into EOIB and WI groups. Both procedures were performed using 40 mL of 0.25% levobupivacaine. The primary outcome was the numerical rating scale (NRS) score 12 h postoperatively. Secondary outcomes were NRS at 2, 24, and 48 h postoperatively, variation in quality of recovery-15 score on postoperative days 1 and 2 from preoperative baseline, postoperative fentanyl consumption, and variation in World Health Organization Disability Assessment Scale 2.0 scores between baseline and 3 months postoperatively. Plasma concentrations of levobupivacaine and pinprick sensation in the T4-11 dermatomes post-EOIB were evaluated to determine the exploratory endpoints. Results: There were no differences in the NRS scores 12 h postoperatively at rest and during movement between the EOIB and WI groups (mean standard deviation 1.3 [1.1] vs. 1.5 [1.4] and 3.1 [1.6] vs. 3.8 [1.7], respectively). Secondary outcomes did not differ significantly between the groups. The time to peak plasma concentration of levobupivacaine following EOIB was 45 min. Conclusions: No significant differences in NRS scores were observed between the analgesic effects of EOIB and WI at 12 h postoperatively.

RESUMO

INTRODUCTION: Obesity patients undergoing laparoscopic bariatric surgery (LBS) are frequently encountered perioperative adverse events related to opioids-based anaesthesia (OBA) or opioids-free anaesthesia (OFA). While modified opioid-sparing anaesthesia (MOSA) has been shown to lower the occurrence of adverse events related to OBA and OFA. This study is to assess the efficacy of MOSA in enhancing the recovery quality among individuals undergoing LBS. METHODS AND ANALYSIS: A single-centre, prospective, double-blind, randomised controlled trial is conducted at a tertiary hospital. A total of 74 eligible participants undergoing elective LBS will be recruited and randomly allocated. Patients in the MOSA group will receive a combination of low-dose opioids, minimal dexmedetomidine, esketamine and lidocaine, while in the OBA group will receive standard general anaesthesia with opioids. Patients in both groups will receive standard perioperative care. The primary outcome is the quality of recovery-15 score assessed at 24 hours after surgery. Secondary outcomes include pain levels, anxiety and depression assessments, gastrointestinal function recovery, perioperative complication rates, opioid consumption and length of hospital stay. ETHICS AND DISSEMINATION: Ethical approval has been provided by the Ethical Committee of Yan'an Hospital of Kunming City (approval No. 2023-240-01). Eligible patients will provide written informed consent to the investigator. The outcomes of this trial will be disseminated in a peer-reviewed scholarly journal. TRIAL REGISTRATION NUMBER: The study protocol is registered at https://www.chictr.org.cn/ on 19 December 2023. (identifier: ChiCTR2300078806). The trial was conducted using V.1.0.

RESUMO

BACKGROUND: Dermatosurgical procedures are predominantly performed under local anesthesia, yet there are few studies on perioperative pain management for extensive or staged procedures under local anesthesia. The purpose of this study was to assess pain during dermatologic surgery, describe perioperative pain management, and identify factors that influence pain perception. PATIENTS AND METHODS: This prospective, monocentric study included inpatients undergoing dermatologic surgery under local anesthesia from April to December 2021. Preoperative demographic data, a pain questionnaire, and four psychometric questionnaires (PCS, LOT-R, SFQ, PHQ-9) were collected. Postoperative pain and analgesic use during the first 24 hours were recorded. RESULTS: A total of 120 patients (with a total of 191 interventions) were included in the study. Mean postoperative pain was reported to be very low (NRS < 2). Preoperative pain and expected postoperative pain were found to be predictive of postoperative pain. There was a strong correlation between catastrophizing and preoperative anxiety (r = 0.65) and a moderate correlation between depression and preoperative anxiety (r = 0.46). CONCLUSIONS: Dermatologic surgery under local anesthesia is generally considered painless. During preoperative counseling and assessment, attention should be paid to patients who fear surgery, report pain, or anticipate postoperative pain, as they have an increased risk of experiencing postoperative pain.

RESUMO

BACKGROUND: Factor VII deficiency is considered a contraindication to neuraxial anesthesia due to the risk of an epidural hematoma. CASE REPORT: A 32 year old G1P0 parturient with severe factor VII deficiency presented for an anesthesiology consultation at 32 weeks gestation. Initial coagulation studies were significant for an elevated INR (2.0) and a low factor VII level of 6%. After interdisciplinary discussion, it was decided that neuraxial analgesia could be offered if her coagulation studies corrected after administration of recombinant activated factor VII (rFVIIa). The patient presented at 36 weeks gestation for a rFVIIa challenge. She received 22 mcg/kg rFVIIa and coagulation studies were analyzed 20 minutes later which showed complete correction of the coagulopathy. The patient presented to the hospital at 39 weeks and 3 days for delivery, received 2 mg rFVIIa and 20 minutes later, successfully received an epidural catheter. Her INR was monitored every 3 hours during her labor course and rFVIIa was given if the INR was 1.3 or greater. She required three additional doses over 22 hours. No bleeding or thrombotic events occurred, and the patient was discharged home without complications. CONCLUSION: This case highlights the safe management of an epidural catheter in a parturient with severe factor VII deficiency.

RESUMO

INTRODUCTION: Poststroke spasticity (PSS) affects up to 40% of patients who had a stroke. Botulinum neurotoxin type A (BoNT-A) has been shown to improve spasticity, but the optimal timing of its application remains unclear. While several predictors of upper limb PSS are known, their utility in clinical practice in relation to BoNT-A treatment has yet to be fully elucidated. The COLOSSEO-BoNT study aims to investigate predictors of PSS and the effects of BoNT-A timing on spasticity-related metrics in a real-world setting. METHODS AND ANALYSIS: The recruitment will involve approximately 960 patients who have recently experienced an ischaemic stroke (within 10 days, V0) and will follow them up for 24 months. Parameters will be gathered at specific intervals: (V1) 4, (V2) 8, (V3) 12, (V4) 18 months and (V5) 24 months following enrolment. Patients will be monitored throughout their rehabilitation and outpatient clinic journeys and will be compared based on their BoNT-A treatment status-distinguishing between patients receiving treatment at different timings and those who undergo rehabilitation without treatment. Potential predictors will encompass the Fugl-Meyer assessment, the National Institute of Health Stroke Scale (NIHSS), stroke radiological characteristics, performance status, therapies and access to patient care pathways. Outcomes will evaluate muscle stiffness using the modified Ashworth scale and passive range of motion, along with measures of quality of life, pain, and functionality. ETHICS AND DISSEMINATION: This study underwent review and approval by the Ethics Committee of the Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy. Regardless of the outcome, the findings will be disseminated through publication in peer-reviewed journals and presentations at national and international conferences. TRIAL REGISTRATION NUMBER: NCT05379413.

RESUMO

Chronic pain is a complex condition that often poses diagnostic and management challenges due to its multifactorial etiology. This case report describes a 49-year-old pastor who presented with a three-year history of chronic pain affecting multiple sites, including the neck, bilateral shoulders, thoracic region, lower back, and bilateral knees. Additionally, he experienced shortness of breath on mild exertion, which adversely affected his ability to converse and speak publicly. The patient had a rapid resting heart rate of 100-120 beats per minute, occasional palpitations, and a 24-hour electrocardiogram that confirmed 15% premature ventricular complexes with bigeminy and trigeminy. He complained of limited appetite with early satiety, intermittent nausea, and regurgitation. Despite consultations with multiple specialists, no underlying causes were identified in the cardiac, respiratory, gastrointestinal, or psychological domains. Ultrasound-guided bilateral vagus nerve hydrodissection using 5% dextrose without local anesthetics was administered three times at monthly intervals, resulting in remarkable pain relief within three months and the effects persisted at the nine-month follow-up. Tachycardia was no longer perceived, resting heart rate slowed to 70-80 beats per minute, shortness of breath improved, and public speaking ability was restored. The patient's early satiety, nausea, and reflux complaints were resolved. This case report highlights the potential effectiveness of this novel intervention for chronic pain. Further research is warranted to validate these findings and explore the mechanism of action.

RESUMO

BACKGROUND: Spinal cord stimulation (SCS) provides pain relief for some patients with persistent spinal pain syndrome type 2 (PSPS 2), but the precise mechanisms of action and prognostic factors for a favorable pain response remain obscure. This in vivo human genome-wide association study provides some pathophysiological clues. METHODS: We performed a high-density oligonucleotide microarray analysis of serum obtained from both PSPS 2 cases and pain-free controls who had undergone lower back spinal surgery at the study site. Using multivariate discriminant analysis, we tried to identify different expressions between mRNA transcripts from PSPS 2 patients relative to controls, SCS responders to non-responders, or SCS responders to themselves before starting SCS. Gene ontology enrichment analysis was used to identify the biological processes that best discriminate between the groups of clinical interest. RESULTS: Thirty PSPS 2 patients, of whom 23 responded to SCS, were evaluated together with 15 pain-free controls. We identified 11 significantly downregulated genes in serum of PSPS 2 patients compared with pain-free controls and two significantly downregulated genes once the SCS response became apparent. All were suggestive of enhanced inflammation, tissue repair mechanisms and proliferative responses among the former. We could not identify any gene differentiating patients who responded to SCS from those who did not respond. CONCLUSIONS: This study points out various biological processes that may underlie PSPS 2 pain and SCS therapeutic effects, including the modulation of neuroimmune response, inflammation and restorative processes.

RESUMO

BACKGROUND: Dexamethasone palmitate (DEP), a prodrug of dexamethasone (DEX), is a synthetic corticosteroid medication distinguished by the inclusion of a fatty acid component known as palmitate. This study introduces DEP as a novel therapeutic option for spinal epidural injection, aiming to provide safer and longer-lasting pain relief as an alternative to for patients with spinal stenosis. METHODS: 40 rats were randomly divided into four groups: those receiving epidural administration of normal saline (NS), and DEP in the lumbar spinal stenosis (LSS) model, and non-model rats receiving epidural NS administration. Paw withdrawal thresholds to mechanical stimulation and motor function (neurogenic intermittent claudication) were observed for up to 21 days. Hematology and blood chemistry analyses were performed 1 week after drug therapy. Tissue samples were collected for steroid pathology examination to evaluate adhesion degree, perineural area inflammation, and chromatolysis in the dorsal root ganglion (DRG), and adrenal gland. RESULTS: The DEX and DEP groups demonstrated significant recovery from mechanical allodynia and motor dysfunction after 2 weeks of drug therapy (p<0.001). However, by the third week, the effect of DEX started to diminish while the effect of DEP persisted. Furthermore, the DEP group exhibited reduced fibrosis and less chromatolysis than the NS group. No steroid overdose or toxin was observed in any group. CONCLUSION: The epidural administration of DEP demonstrated therapeutic efficacy in reducing allodynia and hyperalgesia resulting from chronic DRG compression, thus offering prolonged pain relief. These findings underscore the potential of DEP as a promising treatment alternative for pain associated with LSS, serving as a viable substitute for .

RESUMO

We present the case of a 56-year-old female with a significant medical history of cholelithiasis and recurrent choledocholithiasis. Following an elective cholecystectomy, an obstructing gallstone in the common bile duct led to a series of interventions, including endoscopic retrograde cholangiopancreatography and stent placement. The patient was scheduled for a robot-assisted laparoscopic common bile duct exploration. Due to severe adhesions, the procedure was converted to open with a large right upper quadrant incision. Intraoperative continuous external oblique block and catheter placement were performed at the end of surgery in the OR. Peripheral nerve blocks have become an integral part of multimodal pain management strategies. This case report describes the successful implementation of an ultrasound-guided right external oblique intercostal block and catheter placement for postoperative pain control and minimization of opioids. This case highlights the efficacy and safety of ultrasound-guided peripheral nerve blocks for postoperative pain management. Successful pain control contributed to the patient's overall postoperative recovery.

RESUMO

Pain management is often difficult in the setting of multi-site trauma such as that caused by motor vehicle accidents (MVA), which is especially compounded in the setting of polysubstance abuse. This often results in patients with poor pain tolerance requiring escalating doses of opioid therapy, which creates a vicious cycle. The use of peripheral nerve blocks (PNB) has been shown to decrease overall opioid consumption and can be used effectively to manage postoperative pain in this patient population. Our case report aims to highlight the importance of PNBs as part of a multimodal approach to pain management in patients with polytrauma in the setting of polysubstance abuse.
