Multicenter Study Observational Study
Phenotyping peripheral neuropathies with and without pruritus: a cross-sectional multicenter study.
Pruritus often escapes physicians' attention in patients with peripheral neuropathy (PNP). Here we aimed to characterize neuropathic pruritus in a cohort of 191 patients with PNP (large, mixed, or small fiber) and 57 control subjects with deep phenotyping in a multicenter cross-sectional observational study at 3 German sites. All participants underwent thorough neurological examination, nerve conduction studies, quantitative sensory testing, and skin biopsies to assess intraepidermal nerve fiber density. ⋯ The pruritus group had lower intraepidermal nerve fiber density at the thigh, concomitant with a more proximal distribution of symptoms compared with the other PNP groups. Stratification of patients with PNP by using cross-sectional datasets and multinominal logistic regression analysis revealed distinct patterns for the patient groups. Together, our study sheds light on the presence of neuropathic pruritus in patients with PNP and its relationship with neuropathic pain, outlines the sensory and structural abnormalities associated with neuropathic pruritus, and highlights its impact on anxiety levels.

While interdisciplinary multimodal pain treatment (IMPT) is an effective treatment option for chronic low back pain, it is usually accomplished as an inpatient treatment incurring substantial healthcare costs. Day hospital IMPT could be a resource-saving alternative approach, but whether treatment setting is associated with differences in treatment outcomes has not yet been studied. In a retrospective matched cohort study including data from N = 595 patients diagnosed with chronic back pain and undergoing IMPT at the back pain center in Essen, Germany, we investigated the association between treatment setting (ie, inpatient or day patient of an otherwise identical IMPT) and pain intensity, disability, and self-efficacy after treatment. ⋯ Moreover, day patients achieved higher scores in pain-related self-efficacy at discharge, 3- and 6-month post-IMPT (d = 0.62, 0.99, and 1.21, respectively) and reported fewer incapacity-for-work days than inpatients at 6-month post-IMPT (d = 0.45). These data suggest that day hospital IMPT can be as effective as inpatient treatment and might even be more effective for the less afflicted patients. Further research regarding treatment setting and indication could guide optimized and cost-efficient treatments that are more closely tailored to the individual patient's needs.

Many patients experience acute pain, which has been associated with numerous negative consequences. Pain education has been proposed as a strategy to improve acute pain management. However, studies report limited effects with educational interventions for acute pain in adults, which can be explained by the underuse of the person-centered approach. ⋯ The most frequently reported educational preferences were for in-person education while involving caregivers and to obtain information first from physicians, then by other professionals. This review has highlighted the needs and preferences to be considered in pain education interventions, which should be embedded in an approach cultivating communication and partnership with patients and their caregivers. The results still need to be confirmed with different patient populations.

Data were obtained from the Global Burden of Disease study 2019. Joinpoint regression model was used to analyze the temporal trends from 1990 to 2019 of neck pain burden, focusing on age-standardized incidence rates, age-standardized prevalence rates, and age-standardized years lived with disability (YLDs) rates at the global, regional, and national levels. The age-period-cohort analysis was used to estimate the effects of age (5-99 years), period (1990-2019), and cohort (1893-2012) at the global, regional, and national levels. ⋯ Compared with 2019, the incident cases, prevalent cases, and YLDs counts of neck pain were projected to increase by 134%, 142%, and 140% by 2044. The global burden of neck pain has persisted at a relatively elevated level from 1990 to 2019, with projections indicating a continuing upward trend. Future research is urgently needed to better understand the predictors and clinical course of neck pain and to enhance prevention and management strategies.
