This study aimed to explore the pathways between family functioning and mental health in people with neuropathic pain, as well as to discuss the mediating role of pain intensity, self-perceived burden, pain catastrophizing, and functional status. ⋯ Nurses' comprehensive assessment and management of neuropathic pain from both the family and individual levels, such as family functioning, pain intensity, self-perceived burden, pain catastrophizing, and functional status, may be beneficial in promoting patients' mental health. In addition, it is necessary to identify why good family functioning is associated with higher pain intensity and intervene in this regard.

Botulinum toxin (BoNT), a presynaptic inhibitor of acetylcholine (Ach) release at the neuromuscular junction (NMJ), is a successful and safe drug for the treatment of several neurological disorders. However, a wide and recent literature review has demonstrated that BoNT exerts its effects not only at the "periphery" but also within the central nervous system (CNS). Studies from animal models, in fact, have shown a retrograde transport to the CNS, thus modulating synaptic function. ⋯ In this new light, BoNT might interfere with the activity of spinal, brain stem, and cortical circuitry, modulating excitability and the functional organization of CNS in healthy conditions. Botulinum toxins efficacy on CNP is the result of a wide and complex action on many and diverse mechanisms at the basis of the maladaptive plasticity, the core of the pathogenesis of CNP. This systematic review aims to discuss in detail the BoNT's mechanisms and effects on peripheral and central neuroplasticity, at the basis for the clinical efficacy in CNP syndromes.

Randomized Controlled Trial
CT-guided Dorsal Root Ganglion Ozone Injection Combined With Pulsed Radiofrequency for Acute Herpes Zoster Neuralgia Treatment of Middle-aged and Elderly People: A Randomized, Double-Blinded, Controlled Trial.
To investigate the efficacy and safety of pulsed radiofrequency of the dorsal root ganglion combined with ozone injection for treating acute herpes zoster (HZ) neuralgia in middle-aged and elderly adults. ⋯ The results indicated that ozone injection in the dorsal root ganglion combined with pulsed radiofrequency therapy was more effective in treating acute HZ neuralgia in middle-aged and elderly adults. It provides patients with longer-lasting pain relief, decreased incidence of PHN and the doses of medication, and improved quality of life than with Pulsed Radiofrequency treatment.

Pain catastrophizing is a significant factor in the recovery of patients with chronic pain. This topic has not received the warranted attention in clinical practice, while the outcomes of pain interventions have been suboptimal. This study explores the current situation of pain catastrophizing in patients with chronic neuropathic pain, its influencing factors, and further analyzes the complex relationship between these factors. ⋯ Pain severity, disease type, alexithymia, psychological resilience, and somatization all had a significant effect on pain catastrophizing. Healthcare workers must provide timely and accurate assessments of patients' pain levels to help prevent the onset of pain catastrophizing. Adopting measures to improve alexithymia and somatization symptoms, and focusing on enhancing patients' psychological resilience can also help reduce the level of pain catastrophizing. Cognitive behavioral therapy may be an effective treatment method for pain catastrophizing.

Quantitative sensory testing (QST) has been used for decades to study sensory abnormalities in multiple conditions in which the somatosensory system is compromised, including pain. It is commonly used in pharmacologic studies on chronic pain but less so in conjunction with neuromodulation. This review aims to assess the utility of QST in spinal cord stimulation (SCS) protocols. ⋯ We recommend the adoption of QST into future clinical research protocols, using either the full QST protocol or a less time-demanding short-form QST.
