Even though pruritus affects a significant number of people with chronic disease, it is rarely adequately treated. Drug therapies often rely on antihistamines, which have not shown to be beneficial in systemic pruritus. ⋯ Although there is literature describing itch in patients with cancer, this article is limited to pathogenesis and treatment of systemic itch secondary to chronic, noncancer diseases. We summarize recent systematic reviews, although the studies included in these reviews are often small, and mostly cohort studies.

Neuropathic pain in burn patients - A common problem with little literature: A systematic review.
The prevalence of neuropathic pain (NP) in burn patients is reported in the literature to be as high as 80%1. Given the complexity of NP in burn patients and the wide range of treatments available, a systematic review of the literature is warranted to summarize our current understanding of management and treatment of NP in this population. ⋯ Despite NP afflicting the majority of burn patients long after their injury, this systematic review demonstrates insufficient evidence on the pathophysiology, outcomes, and risk factors in NP, as well as the efficacy of various therapies. Future prospective and randomized studies evaluating the etiology of these factors can substantially improve our treatment strategies. This can allow for the development of well-delineated and evidence-based protocols in NP management in hopes of improving quality of life and both psychological and physical function in burn patients.

Exploring the interplay of atopic dermatitis severity with sleep and mental health: a case-control study in adult patients.
Atopic dermatitis (AD) is a chronic inflammatory skin disease often associated with non-atopic comorbidities. Recently, a severity-dependent relationship between AD and sleep/mental health diseases has been proposed. However, few studies investigated these comorbidities and their association with AD severity through validated questionnaires. This study aimed to use a set of validated instruments to assess the impact of AD on sleep and psychological disorders and estimate the association of itch and AD severity with sleep disorders and psychological symptoms, distinguishing between clinical-oriented and patient-oriented measures. ⋯ The study demonstrated poor sleep quality and high levels of insomnia, depression, and stress in AD patients, with an aggravated psychological status for adults with more severe skin disease. We suggest implementing a multidisciplinary approach to AD management/treatment that considers objective and subjective measures of disease severity.

Post-burn pruritus is one of the most common complaints reported by patients with limited evidence for a gold-standard treatment. ⋯ Current evidence suggests that current modalities have a statistically significant, but not clinically significant, reduction in pruritus. This review highlights the limited quality of evidence in the literature and the poor quality of reporting among excluded studies.

The current study aims to characterize brain morphology of pain as reported by small fiber neuropathy (SFN) patients with or without a gain-of-function variant involving the SCN9A gene and compare these with findings in healthy controls without pain. The Neuropathic Pain Scale was used in patients with idiopathic SFN (N = 20) and SCN9A-associated SFN (N = 12) to capture pain phenotype. T1-weighted, structural magnetic resonance imaging (MRI) data were collected in patients and healthy controls (N = 21) to 1) compare cortical thickness and subcortical volumes and 2) quantify the association between severity, quality, and duration of pain with morphological properties. ⋯ The association between itch sensations of pain and sensorimotor and midcingulate structures provides a novel basis for further examining neurobiological underpinnings of itch in SFN. PERSPECTIVE: Cortical thickness and subcortical volume alterations in SFN patients were found in pain hubs, more profound in SCN9A-associated neuropathy, and correlated with itch and durations of pain. These findings contribute to our understanding of the pathophysiological pathways underlying chronic neuropathic pain and symptoms of itch in SFN.
