Neuropathic pain encompasses a spectrum of conditions that can arise from a lesion or dysfunction of the central or the peripheral nervous system, and it may develop at variable intervals after nerve injury or inflammation. Nerve injuries arising from surgical procedures commonly occur secondary to the surgical trauma, and in rare instances they are a complication of intubation during general anesthesia or endoscopic procedures. A series of 2 cases of bilateral glossopharyngeal neuropathic pain subsequent to endoscopic procedures is presented with a review of the literature concerning the mechanisms of development of neuropathic pain after these procedures. The purpose of these case reports is to make dentists aware of the occurrence, the mechanisms of nerve injuries, and the treatment of neuropathic pain after endoscopic procedures. In the first case, the patient had relief of pain with a combination therapy of clonazepam 1.0 mg in divided doses twice daily and gabapentin 300 mg in divided doses 3 times daily. In the second case, the patient had significant relief of pain with a monotherapy of gabapentin 1200 mg in divided doses 3 times daily.

Chronic postoperative pain after breast surgery is a significant concern, with studies indicating varying rates depending on the type of surgical procedure. The risk of developing neuropathic pain is notably increased with axillary lymph node dissection due to potential nerve injuries. Additionally, the method of breast reconstruction may influence postsurgical pain rates, with conflicting findings on the impact of reconstruction type.

Pain is a prevalent issue among patients, requiring effective management to prevent the transition of acute pain into chronic pain and to mitigate significant clinical and socioeconomic impacts, such as increased morbidity, mortality, prolonged recovery, unplanned readmissions, and diminished quality of life. Despite advancements in pain management guidelines, achieving consistent pain relief remains challenging due to individual differences in pain thresholds, the nature of surgical procedures, patient age, and existing comorbidities. Tapentadol, an opioid that acts as both a μ-opioid receptor agonist and a noradrenaline reuptake inhibitor, presents a promising option for pain management.

The endocannabinoid system (ECS), which is composed of endocannabinoids (eCBs), cannabinoid receptors (CBRs), and associated signaling molecules, has been identified within the brain. In neuropathic pain animal models and patients, long-lasting alterations in the ECS have been observed. These changes of neurons and glial cells in the ECS contribute to the modulation of neuropathic pain.

Neuropathic pain, one of the most refractory pain diseases, remains a formidable medical challenge. There is still an unmet demand for effective and safe therapies to address this condition. Herein, a rat model of nerve injury-induced neuropathic pain is first established to explore its pathophysiological characteristics.

Hyperoside, a natural flavonoid, exhibits a wide range of biological activities, including analgesic effects on acute and chronic inflammatory pain. This study illustrates that repeated intraperitoneal administration or microinjection of hyperoside into the ventrolateral periaqueductal grey (vlPAG) alleviated mechanical allodynia, cold allodynia, and abnormal gait induced by spared nerve injury (SNI) in male mice. Furthermore, repeated hyperoside administration suppressed SNI-induced astrocyte reactivity in the vlPAG.
