Neuropathic pain, a disease of the somatosensory nervous system, afflicts many individuals and adequate management with current pharmacotherapies remains elusive. The glutamatergic system of neurons, receptors and transporters are intimately involved in pain but, to date, there have been few drugs developed that therapeutically modulate this system. Glutamate transporters, or excitatory amino acid transporters (EAATs), remove excess glutamate around pain transmitting neurons to decrease nociception suggesting that the modulation of glutamate transporters may represent a novel approach to the treatment of pain. This review highlights and summarizes (1) the physiology of the glutamatergic system in neuropathic pain, (2) the preclinical evidence for dysregulation of glutamate transport in animal pain models, and (3) emerging novel therapies that modulate glutamate transporters. Successful drug discovery requires continuous focus on basic and translational methods to fully elucidate the etiologies of this disease to enable the development of targeted therapies. Increasing the efficacy of astrocytic EAATs may serve as a new way to successfully treat those suffering from this devastating disease.

Objective: To analyze the efficacy and tolerability of aceclofenac in the treatment of patients with acute non-specific musculoskeletal pain in the lower back (ANBP) compared with other NSAIDs (dexketoprofen, nimesulide and lornoxicam), as well as to assess the impact of NSAIDs therapy on the relative risk of recurrence and chronicity of this pathology.
Material And Methods: The study involved 80 patients (47 women and 33 men), average age 52.6 [47.

This study evaluates the clinical impact of comprehensive nursing care on senior patients suffering from postherpetic neuralgia (PHN), a chronic neuropathic pain condition resulting from the reactivation of the varicella-zoster virus. A total of 102 elderly patients diagnosed with PHN and treated at our hospital were divided into two groups: the control group, which received conventional nursing care, and the intervention group, which received comprehensive nursing care. Comparative analyses were conducted on pain levels, sleep quality, symptoms of depression and anxiety before and after the intervention.

In pancreatic cancer, significant alterations occur in the local nervous system, including axonogenesis, neural remodeling, perineural invasion, and perineural neuritis. Pancreatic cancer can impact the central nervous system (CNS) through cancer cell-intrinsic factors or systemic factors, particularly in the context of cancer cachexia. These peripheral and central neuropathic changes exert substantial influence on cancer initiation and progression.

Purpose: Neuropathic corneal pain (NCP) has been recognized as a distinct disease, yet treatment options remain limited. The aim of this pilot study was to explore the effectiveness of extranasal neurostimulation (EXNS) as a potential pain relief strategy for individuals with the peripheral component of NCP.
Methods: A retrospective study was performed to identify patients who were diagnosed with refractory peripheral or mixed NCP and subsequently underwent a single session of EXNS.
