The accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER) lumen leads to ER stress, which is related to cellular reactive oxygen species (ROS) production. Neuropathic pain may result from spinal dorsal horn (SDH) ER stress. In this study, we examined the cause-effect relationship between ER stress and neuropathic pain using the spinal nerve ligation(SNL) rat model. We showed that ER stress was mutually promotive with oxidative stress during the process. We also tested the hypothesis that spinal sensitization arose from reduced activities of GABA-ergic interneurons and that spinal sensitization was mediated by SDH ER stress...

OBJECTIVE: Systemic amyloidosis is a disease that often involves multiple organ systems, including the peripheral nervous system. Patients may present with severe, refractory neuropathic pain; however, the optimal treatment approach for pain for these patients remains unclear. CASE REPORT: A man with severe, refractory neuropathic pain in his bilateral upper and lower extremities and the trunk secondary to amyloid neuropathy is presented. Multiple medication trials, including neuropathic and opioid agents, produced considerable adverse effects and minimal relief...

Neuropathic pain is a complex, chronic pain condition and the treatment is a major clinical challenge. Recent studies have shown that two FDA approved drugs dexmedetomidine (DEX) and midazolam (MZL), may be useful in treating neuropathic pain, but the mechanism is not fully dementated. Here, we investigated the effects and mechanisms of DEX and MZL treatment in the peripheral nerve injury model. Intramuscular injection with DEX and MZL attenuated the development of mechanical allodynia and thermal hyperalgesia in rats with chronic constriction injury (CCI)...

INTRODUCTION: Diabetic peripheral neuropathy (DPN) affects almost 30% to 50% of patients with diabetes, 40% to 60% of whom suffer from diabetic peripheral neuropathic pain (DPNP). Few studies have focused on individual experiences of DPNP in patients with diabetes. The purpose of this qualitative study was to elucidate the effects of DPNP on daily life and individual feelings regarding living with DPNP from the perspective of Turkish patients. METHOD: A total of 14 patients were interviewed, and interpretative phenomenological analysis was used to identify themes...

Cannabinoids appear to possess many potential medical uses, which may extend to pain control. A narrative review of the literature has found a variety of studies testing botanical and synthetic cannabinoids in different pain syndromes (acute pain, cancer pain, chronic noncancer pain, fibromyalgia pain, migraine, neuropathic pain, visceral pain, and others). Results from these studies are mixed; cannabinoids appear to be most effective in controlling neuropathic pain, allodynia, medication-rebound headache, and chronic noncancer pain, but do not seem to offer any advantage over nonopioid analgesics for acute pain...

Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Depending on its pathophysiological mechanism, it may be classified into nociceptive, neuropathic, and mixed pain. If pain is moderate to severe, a strong opioid should be administered and, when this is the case, morphine is the drug of choice. If morphine is ineffective or causes intolerable adverse effects, opioid rotation is recommended. Our objective was to describe the drug management for mixed pain used in patients assisted by the Palliative Care team of Hospital General de Niños Pedro de Elizalde between August 2011 and September 2015...

The use of deep brain stimulation (DBS) of the thalamus has been proven to be a safe and efficacious treatment for the management of many diseases. The most common indication for thalamic DBS remains essential tremor (ET), one of the most common movement disorders in the world. ET patients should be considered for surgical intervention when their tremor has demonstrated to be refractory to medication, a characteristic estimated to be present in roughly 50% of ET cases. Advantages of DBS over thalamotomy include its reversibility, the ability to adjust stimulation settings to optimize efficacy and minimize side effects, the ability to perform bilateral procedures safely, and an association with a lower risk of postoperative cognitive problems...

A painful neuroma is a common complication of a peripheral nerve injury or amputation, and it can cause tremendous pain that is resistant to most analgesics. Furthermore, painful neuromas have a high postoperative recurrence rate. Painful neuromas are often accompanied by functional disorders, drastically reducing the patient's quality of life. Several pathophysiological mechanisms have been proposed to explain this type of neuropathic pain, including peripheral and central sensitisation and the involvement of nerve growth factor, α-smooth muscle actin, the cannabinoid CB2 receptor and structural changes in neuroma fibres...

Following injury to a peripheral nerve, patients may complain of pain over the distribution of the same contralateral nerve, a phenomenon referred to as contralateral pain or mirror pain (MP). Symptoms of MP usually begin after the neuropathic pain from the original nerve injury has become chronic. Chronic neuropathic pain can lead to sensitization and spread of pain. Because the diagnosis of MP can be missed, patients may undergo multiple treatment procedures that prove to be ineffective in relieving the pain...

Meralgia paresthetica is a neuropathic pain disorder resulting from an entrapment neuropathy of the lateral femoral cutaneous nerve. This condition results in pain, paresthesias and numbness over the anterolateral aspect of the thigh. We present a case of meralgia paresthetica and discuss both the clinical and histopathological findings as they relate to one another. We report a case of meralgia paresthetica refractory to conservative treatment who underwent neurectomy with successful treatment of symptoms...

STUDY DESIGN: Cross-sectional study. OBJECTIVES: Central neuropathic pain (CNP) is common after spinal cord injury (SCI). The psychological impact of CNP is not clear. Previous studies reported depression and pain catastrophizing among patients with SCI and CNP; however, the lack of control groups prevented discerning whether these were attributed to CNP or to the SCI itself. The aim was to examine the psychological distress among individuals with SCI with and without CNP and controls to evaluate its impact and possible source...

Video-assisted thoracoscopic surgery is a widespread technique that has been linked to improved postoperative respiratory function, reduced hospital length of stay and a higher level of tolerability for the patients. Acute postoperative pain is of considerable significance, and the late development of neuropathic pain syndrome is also an issue. As anaesthesiologists, we have investigated the available evidence to optimize postoperative pain management. An opioid-sparing multimodal approach is highly recommended...

REVIEW
Karli Montague, Marzia Malcangio
In cancer treatments a dose-limiting side-effect of chemotherapeutic agents is the development of neuropathic pain, which is poorly managed by clinically available drugs at present. Chemotherapy-induced painful neuropathy (CIPN) is a major cause of premature cessation of treatment and so a greater understanding of the underlying mechanisms and the development of novel, more effective therapies, is greatly needed. In some cases, only a weak correlation between chemotherapy-induced pain and neuronal damage is observed both clinically and preclinically...
