Mesaroli G, Davidge KM, Davis AM, Perruccio AV, Choy S, Walker SM, Stinson JN. Age and Sex Differences in Pediatric Neuropathic Pain and Complex Regional Pain Syndrome: A Scoping Review. Clin J Pain 2024; 40:428-439. [PMID: 38616343 DOI: 10.1097/ajp.0000000000001217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 04/02/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND Age and sex differences may exist in the frequency (incidence, prevalence) or symptoms of neuropathic pain (NP) and complex regional pain syndrome (CRPS) due to biopsychosocial factors (eg, neurodevelopment, physiological and hormonal changes, psychosocial differences) that evolve through childhood and adolescence. Age and sex differences may have implications for evaluating screening and diagnostic tools and treatment interventions. OBJECTIVE To map the existing literature on pediatric NP and CRPS with respect to age and sex distributions, and age and sex differences in symptomology and frequency. METHODS A scoping literature review was conducted. Databases were searched from inception to January 2023. Data were collected on study design, setting, demographics, and age and sex differences in frequency and symptoms. RESULTS Eighty-seven studies were included. Distribution of participants with CRPS (n=37 studies) was predominantly early adolescence (10 to 14 y) and female sex, while NP (n=42 studies) was most commonly reported throughout adolescence (10 to 19 y) in both sexes. Forty-one studies examined age and sex differences in frequency; 6 studies reported higher frequency in adolescence. Very few studies (n=11) examined differences in symptomology. DISCUSSION Large epidemiological studies are required to further understand age and sex differences in frequency of pediatric NP and CRPS. Age and sex differences must be considered when evaluating screening and diagnostic tools and treatment interventions to ensure relevance and validity to both sexes and across ages. Validated tools will improve understanding of age-dependent and sex-dependent differences in symptoms, pathophysiology, and psychosocial impact of pediatric NP and CRPS.

Walker SM, Peters J, Verriotis M, Farag F, Jay MA, Howard RF. Sensitivity and Specificity of a Neuropathic Screening Tool (Self-Report Leeds Assessment of Neuropathic Symptoms and Signs, S-LANSS) in Adolescents With Moderate-Severe Chronic Pain. THE JOURNAL OF PAIN 2024; 25:451-465. [PMID: 37741521 DOI: 10.1016/j.jpain.2023.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Revised: 08/27/2023] [Accepted: 09/07/2023] [Indexed: 09/25/2023]
Abstract
Neuropathic screening tools improve recognition of neuropathic pain in adults. Although utilized in pediatric populations, the sensitivity, specificity and methodology of screening tool delivery have not been compared in children. We evaluated the Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) in adolescents (10-18 years) referred to a tertiary pediatric pain clinic. History and examination by specialist clinicians and multidisciplinary assessment informed classification of the primary pain type. In a prospective cohort, scores were obtained at interview (S-LANSS interview; n = 161, 70% female), and following substitution of self-reported signs with examination findings in the primary pain region (Leeds Assessment of Neuropathic Symptoms and Signs, LANSS examination). Secondly, we retrospectively retrieved questionnaires self-completed by adolescents at their initial clinic appointment (S-LANSS self-completed; n = 456, 73% female). Thirdly, we explored relationships between patient-reported outcomes and S-LANSS scores. S-LANSS interview scores varied with pain classification, and S-LANSS self-completed scores were similarly highest with neuropathic pain (median [interquartile range]: 18 [11, 21]) and complex regional pain syndrome (21 [14, 24]), variable with musculoskeletal pain (13 [7, 19]) and lowest with visceral pain (6.5 [2, 11.5]) and headache (8.5 [4, 14]). As in adults, the cutpoint score of 12/24 was optimal. Sensitivity was highest with inclusion of examination findings and lowest with self-completion (LANSS examination vs S-LANSS interview vs S-LANSS self-completed: 86.3% vs 80.8% vs 74.7%), but specificity was relatively low (37.8% vs 36.7% vs 48%). High S-LANSS scores in non-neuropathic groups were associated with female sex and high pain catastrophizing. The S-LANSS is a sensitive screening tool for pain with neuropathic features in adolescents, but needs to be interpreted in the context of clinical evaluation (clinicaltrials.gov NCT03312881). PERSPECTIVE: This article reports high sensitivity of the S-LANSS screening tool for identifying pain with neuropathic features in adolescents with moderate-severe chronic pain. However, as sensitivity is lower than in adult populations, further interdisciplinary evaluation is necessary to inform diagnosis and management.

Phenotyping peripheral neuropathic pain in male and female adolescents: pain descriptors, somatosensory profiles, conditioned pain modulation, and child-parent reported disability. Pain 2021; 162:1732-1748. [PMID: 33394878 DOI: 10.1097/j.pain.0000000000002172] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 11/09/2020] [Indexed: 12/13/2022]
Abstract
ABSTRACT Neuropathic pain (NeuP) can be difficult to diagnose and manage in children. Data regarding prevalence and sex-dependent differences are limited, and more detailed phenotyping is needed. This observational cohort study recruited adolescents (10-17 years) with NeuP or complex regional pain syndrome (CRPS). After pain history and NeuP questionnaires, quantitative sensory testing was performed. Individual z-score plots were calculated with body-region control measures and matched to mechanism-related sensory profiles (sensory loss, thermal hyperalgesia, and mechanical hyperalgesia). Conditioned pain modulation was assessed with pressure pain threshold and a contralateral cold conditioning stimulus, and meaningful conditioned pain modulation defined as twice the standard error of measurement. Patients and parents completed validated questionnaires for child quality of life (QoL), pain catastrophizing, and self-reported anxiety/depression. Males (n = 23) and females (n = 43) with NeuP (n = 52) or CRPS (n = 14) reported moderate-severe pain with neuropathic sensory descriptors. Mixed patterns of sensory gain/loss at pain sites were not sex-dependent. Thermal hyperalgesia was common in both NeuP and CRPS, whereas sensory loss occurred only with NeuP and in a smaller proportion than adult cohorts. Conditioned pain modulation was inhibitory in 54%, facilitatory in 14%, and nonresponders had variable cold conditioning sensitivity. Males and females reported marked impairment of QoL, increased emotional distress, and pain catastrophising. Child-parent QoL scores correlated, but catastrophizing scores were discordant when parents or adolescents reported higher anxiety/depression. NeuP in adolescents is associated with significant pain, physical impairment, and psychosocial impairment. Quantifying alterations in somatosensory profiles, descending modulation, child and parent psychological function will inform individualized therapy and stratification for future clinical trials.

Neuropathic pain in children: Steps towards improved recognition and management. EBioMedicine 2020; 62:103124.

Abstract
Neuropathic pain in children can be severe and persistent, difficult to recognise and manage, and associated with significant pain-related disability. Recognition based on clinical history and sensory descriptors is challenging in young children, and screening tools require further validation at older ages. Confirmatory tests can identify the disease or lesion of the somatosensory nervous system resulting in neuropathic pain, but feasibility and interpretation may be influenced by age- and sex-dependent changes throughout development. Quantitative sensory testing identifies specific mechanism-related sensory profiles; brain imaging is a potential biomarker of alterations in central processing and modulation of both sensory and affective components of pain; and genetic analysis can reveal known and new causes of neuropathic pain. Alongside existing patient- and parent-reported outcome measures, somatosensory system research methodologies and validation of mechanism-based standardised end-points may inform individualised therapy and stratification for clinical trials that will improve evidence-based management of neuropathic pain in children.

Abstract
Validated diagnostic tools to diagnose chronic neuropathic and mixed pain in children are missing. Therapeutic options are often derived from therapeutics for adults. To investigate the international practice amongst practitioners for the diagnosis and treatment of chronic, neuropathic pain in children and adolescents, we performed a survey study among members of learned societies or groups whose members are known to treat pediatric pain. The survey included questions concerning practitioners and practice characteristics, assessment and diagnosis, treatment and medication. We analyzed 117 returned questionnaires, of which 41 (35%) were fully completed and 76 (65%) were partially completed. Most respondents based the diagnosis of neuropathic pain on physical examination (68 (58.1%)), patient history (67 (57.3%)), and underlying disease (59 (50.4%)) combined. Gabapentin, amitriptyline, and pregabalin were the first-choice treatments for moderate neuropathic pain. Tramadol, ibuprofen, amitriptyline, and paracetamol were the first-choice treatments for moderate mixed pain. Consensus on the diagnostic process of neuropathic pain in children and adolescents is lacking. Drug treatment varies widely for moderate, severe neuropathic, and mixed pain. Hence, diagnostic tools and therapy need to be harmonized and validated for use in children.

Abstract
BACKGROUND Advances in pain assessment approaches now indicate which measures should be used to capture chronic pain experiences in children and adolescents. However, there is little guidance on how these tools should best be administered and reported, such as which time frames to use or how pain scores are categorised as mild, moderate, or severe. OBJECTIVE To synthesise current evidence on unidimensional, single-item pain intensity scale selection, administration, interpretation, and reporting. METHODS Databases were searched (inception: 18 January 2016) for studies in which unidimensional pain intensity assessments were used with children and adolescents with chronic pain. Ten quality criteria were developed by modifying existing recommendations to evaluate the quality of administration of pain scales most commonly used with children. RESULTS Forty-six studies met the inclusion criteria. The highest score achieved was 7 out of a possible 10 (median: 5; IQR: 4-6). Usage of scales varied markedly in administrator/completer, highest anchors, number of successive assessments, and time referent periods used. CONCLUSIONS Findings suggest these scales are selected, administered, and interpreted inconsistently, even in studies of the same type. Furthermore, methods of administration are rarely reported or justified making it impossible to compare findings across studies. This article concludes by recommending criteria for the future reporting of paediatric chronic pain assessments in studies.

Abstract
There have been significant advances in the treatment of acute pain in children alongside increased academic interest in the field. This has led to improvements in both efficacy and safety alongside the development of multidisciplinary pain services. Despite this, however, there are still high rates of acute pain reported in children in both inpatient and outpatient settings. In this article, we discuss some of the challenges faced by healthcare workers in designing effective multidisciplinary treatment regimens, understanding the implications for long-term pain and pain processing of acute pain and analgesic interventions as well as ongoing issues around research, education and resource.

Abstract
We reviewed the referral pattern of children with chronic pain to a specialized pediatric pain clinic. Data were obtained from referring physicians and medical records and during an interview with patients and their parents by physicians and a psychologist. We analyzed the following: referral diagnosis, demographics, duration of symptoms, number of physicians previously consulted, school attendance, sports activities, presence of psychological disorders, final team diagnosis, and outcomes. Children had been experiencing pain for 34 ± 55 months. Patients had consulted on average 3 physicians in addition to their pediatrician. 32% of the patients had missed at least 10 days of school in a calendar year, and 47% had stopped playing sports. 15% had an operation because of pain that had been unsuccessful. The most common missed diagnosis was anxiety (25%) and depression (13%). 69% of the patients were back to school and/or playing sports within 4 months from our initial consultation. 32% of the patients did not make any progress during the follow-up period. The most common reasons for failure to improve were no compliance with the recommended treatments and poorly controlled major mood disorder. The time to refer children with chronic pain for specialized care could be extremely long causing significant social and psychological consequence.

Abstract
PURPOSE The aim of this study was to explore how children aged 10-18 years describe their neuropathic pain (NP). METHOD This is a qualitative descriptive study using inductive content analysis. Semi-structured interviews were conducted with eight children, aged 10-18 years with varying diagnoses, who were experiencing NP. RESULTS All children were able to describe their NP using a variety of strategies, including use of literal and figurative language. While some sensory descriptors commonly reported by adults were used, descriptions of NP pattern and impact were also integral to their narratives. Children were able to differentiate NP from nociceptive pain. Parents clarified and gave context to pain reports. CONCLUSIONS NP is a complex experience necessitating consideration of the different ways that children describe their symptoms. Involvement of parents is invaluable to the process of taking a pain history with a child who is being screened for NP. Implications for Rehabilitation The findings of the study may inform the screening process for NP in children to facilitate earlier identification. Clinicians should consider the variety of ways that children may express their NP symptoms and the resulting impact. Clinicians should probe further when children report that symptoms are hard to describe or "weird". Presence of a parent during the child's pain assessment may assist with gathering a more complete picture.

A randomized controlled trial of amitriptyline versus gabapentin for complex regional pain syndrome type I and neuropathic pain in children. Scand J Pain 2016; 13:156-163.

Abstract
BACKGROUND Treatment of neuropathic pain in children is challenging, and requires a multimodal approach of pharmacologic, physical, and psychological therapies; however there is little evidence to guide practice. Amitriptyline and gabapentin are first-line drugs for treating neuropathic pain in adults, yet no studies have examined their efficacy, or compared them directly, to determine which might be better for pain relief and sleep disturbance in children. METHODS After informed consent was obtained, 34 patients aged 7-18 years diagnosed with complex regional pain syndrome type I (CRPS I) or a neuropathic pain condition were randomly allocated to receive either amitriptyline or gabapentin. Patients were followed for 6 weeks and assessed for pain intensity, sleep quality and adverse events. We blinded study personnel, including health-care providers, participants, parents, the research coordinator and the data analyst. Patients then completed quantitative sensory testing (QST) and a psychosocial pain assessment with the team psychologist, within 1-3 days of the start of the trial. RESULTS At the end of the 6-week trial, patients on both drugs had important reductions in pain, having surpassed the minimally important difference (MID) of 1. The difference between the groups however was not statistically significant. For the secondary outcomes, we found no statistically significant difference between the two drugs in sleep score or adverse events suggesting that both drugs improve sleep score to a similar degree and are equally safe. CONCLUSIONS Amitriptyline and gabapentin significantly decreased pain intensity scores and improved sleep. There were no significant differences between the two drugs in their effects on pain reduction or sleep disability. IMPLICATIONS Although larger, multi-centred trials are needed to confirm our findings, including long-term follow-up, both drugs appear to be safe and effective in treating paediatric patients in the first-line treatment of CRPS I and neuropathic pain over 6-weeks.

Abstract
PURPOSE OF REVIEW This article summarizes recent data related to the safety and efficacy of postoperative analgesia in children that influence clinical practice recommendations. RECENT FINDINGS Postoperative pain continues to be experienced by hospitalized children and following discharge after short stay or ambulatory surgery. Updated recommendations for post-tonsillectomy analgesia exclude codeine and suggest regular administration of paracetamol and NSAID, but evidence for the most appropriate dose and type of opioid for rescue analgesia is limited. The incidence of opioid-related respiratory depression/oversedation in hospitalized children ranges from 0.11 to 0.41%, with recent large series identifying high-risk groups and contributory factors that can be targeted to minimize the risk of serious or permanent harm. Data demonstrating feasibility and safety of regional analgesic techniques is increasing, but additional and procedure-specific evidence would improve technique selection and inform discussions of efficacy and safety with patients and families/carers. Persistent postsurgical pain is increasingly recognized following major surgery in adolescents. Evaluation of potential predictive factors in clinical studies and investigation of underlying mechanisms in laboratory studies can identify targets for both pharmacological and nonpharmacological interventions. SUMMARY Recommendations for postoperative pain in children continue to evolve, with data incorporated from randomized controlled trials, case series and large audits. Management of pain following surgery in children needs to not only encompass efficacy and safety in the immediate perioperative period, but also consider pain following discharge after ambulatory surgery and the potential risk of persistent postsurgical pain following major surgery.

Abstract
PURPOSE OF REVIEW This review highlights new data and current trends of well tolerated and effective paediatric regional anesthesia. Historically, the practice of paediatric regional anesthesia was based largely on information from adult studies, but recent literature contains information on paediatric specific risks and benefits of old and new techniques as well as the impact of new ideas and technologies. RECENT FINDINGS Excellent pain relief with regional anesthesia is well demonstrated in children. Several databases of paediatric regional anesthesia (over 46,000 regional anesthetics) demonstrate overall safety and lack of major complications. Detailed analysis demonstrates additional safety and decreased failure rates of peripheral compared with neuraxial nerve blocks. Ultrasound technology confers additional safety and efficacy benefits.Increasingly, data support the safety and efficacy of novel peripheral nerve blocks, transversus abdominis plane and ultrasound-guided paravertebral, and the use of perineural catheters for both inpatients and outpatients. Regional anesthesia as a sole agent for surgical anesthesia and the use of regional anesthesia for pain in nonsurgical pain patients remains underutilized. SUMMARY Paediatric specific data for regional anesthesia are available to help guide optimal pain management. The paediatric regional anesthesia literature lags behind literature available for adult populations and increased studies are needed for additional information for informed decision-making.
