“…If diagnosed of CPSP, a douleur neuropathic 4-questionnaire (DN-4) was followed to ascertain whether the pain was a neuropathic Pain (NP). DN-4 is an instrument evaluating pain characteristics through 10 items, total score being 10 [ 9 , 10 ]. If the patient score is ≥ 4, neuropathic pain is diagnosed.…”

BackgroundChronic post-surgical pain (CPSP) after hysterectomy has been recognized as a major clinical problem in the Western World. Reports on post-hysterectomy pain are relatively scarce in China. The aim of the current study was to prospectively investigate the incidence and the potential risk factors of CPSP at 3 months following hysterectomy in Chinese population.MethodsWe assessed and collected data on preoperative socio-demographic characteristics, preexisting pain, anxiety and depression, sexual satisfaction, intra-operative variables, and acute postoperative pain intensity in a cohort of 870 women undergoing hysterectomy. The participants were interviewed to determine their suitability to diagnostic criteria of CPSP 3 months later. Logistic regression analyses were subsequently performed to identify predictors for CPSP.ResultsThe incidence of CPSP at 3 months after hysterectomy was 27.7%. Most of the women with CPSP suffered from mild pain and had a slight impact on daily life with sleep and emotion functional limitation. Risk factors for CPSP after hysterectomy were preoperative anxiety, depression, pelvic pain, preexisting pain, very-moderate sexual dissatisfaction, and acute postoperative pain at movement. Intra-operative dexmedetomidine infusion with 0.5 μg/kg/h was associated with a decreased incidence rate of chronic post-hysterectomy pain.ConclusionTwenty-eight percent of patients after hysterectomy in southern Jiangsu china had CPSP with 92% of those women describing it as mild with sleep and emotion functional limitation. Patients with preoperative anxiety and depression, poor sexual satisfaction, preexisting pain, and acute postoperative pain on movement have been identified to be at risk to develop CPSP.

“…48,56 Indeed, pain affects 20% to 40% of the general population in Latin America (LA) and constitutes a major public health challenge. 39,88,92,93,112 The most frequent pain syndromes are osteoarthritis-related pain, low back pain (LBP), headaches, and neuropathic pain syndromes. 2,5,39,40,92,93,95 For instance, the lifetime prevalence of acute LBP is close to 70%, and it has been suggested that more than half will eventually experience chronification, 12,47 ranking chronic LBP as the first cause of years lived with disability 80,114 worldwide.…”

“…Despite this, few studies have examined the prevalence of NeP in Brazil or examined NeP-related outcomes. Those studies that do exist have reported NeP estimates of 60% among those with chronic pain11 and 10% among the general population 12. Additionally, there does not appear to be any studies reporting the impairment associated with specific NeP etiologies.…”

ObjectivesEstimate the prevalence of neuropathic pain (NeP) among chronic pain patients attending Brazilian hospitals and pain clinics in São Paulo, Ceara, and Bahia and explore clinical characteristics by subtypes: painful diabetic peripheral neuropathy (pDPN), central neuropathic pain (CNP), chronic low back pain with a neuropathic component (CLBP-NeP), postherpetic neuralgia (PHN), post-traumatic neuropathic pain (PTN), and post-surgical neuropathic pain (PSN).MethodsPhysicians screened patients reporting chronic pain for ≥3 months (n=2,118) for probable NeP, using the Douleur Neuropathique 4 questionnaire and physician assessment, and reported their NeP subtype(s), symptoms, and medications. Identified NeP patients completed a questionnaire including treatment experiences, quality of life EuroQol 5 Dimensions [EQ-5D]), pain severity and interference (Brief Pain Inventory [BPI]), and Work Productivity and Activity Impairment scales. Descriptive analyses were performed by NeP subtype.ResultsThe prevalence of probable NeP was 14.5% (n=307). NeP patients were mostly female (80.5%), middle-aged (mean [M]=52.5, SD=13.9), and Pardo (44.3%). Of those diagnosed with an NeP subtype (n=209), the largest proportions were CLBP-NeP (36.8%), followed by pDPN (18.7%), CNP (17.7%), PTN (17.2%), PSN (13.4%), and PHN (3.3%). Across subtypes, the most widely reported symptoms were numbness (range: 62.2%–89.7%) and hyperalgesia (range: 32.1%–76.9%) and the most commonly prescribed pain analgesics were NSAID (range: 18.2%–57.1%), opioids (range: 0.0%–39.3%), and antiepileptics (range: 18.2%–57.1%). PTN and PSN patients reported the least favorable EQ-5D index scores (M=0.42, SD=0.19) and BPI-Pain Severity scores (M=7.0, SD=1.9), respectively. Those diagnosed with CNP had the least favorable BPI-Pain Interference scores (M=6.0, SD=2.7). Patients with PHN reported the least impairment based on EQ-5D index scores (M=0.60, SD=0.04). Those with pDPN had the most favorable BPI scores (BPI-Pain Severity: M=4.6, SD=2.3; BPI-Pain Interference: M=4.7, SD=2.7).ConclusionEvaluation of chronic pain patients in Brazil yielded a 14.5% probable NeP prevalence. NSAIDs and opioids were commonly used, and there was a high incidence of NeP-related symptoms with varying levels of dysfunction across subtypes.
