Numerous publications describe chronic pain following surgery in both adults and children. However, data in the paediatric population are still sparse and both prevalence of chronic pain after surgery and risk factors of this complication still undetermined. ⋯ Patients scheduled for spine surgery and presenting with preoperative pain should be considered at risk of chronic pain after surgery and managed accordingly by the chronic and/or acute pain team. Postoperative opioid consumption should be lowered as possible by using multimodal analgesia and regional analgesia such as postoperative epidural analgesia.

Dysfunction of GABAergic inhibitory controls contributes to the development of neuropathic pain. We examined our hypotheses that (1) chronic constriction injury (CCI)-induced neuropathic pain is associated with increased spinal GABAergic neuron apoptosis, and (2) hyperbaric oxygen therapy (HBO) alleviates CCI-induced neuropathic pain by inhibiting GABAergic neuron apoptosis. ⋯ Increased apoptotic GABAergic neurons induced by activation of key proteins of mitochondrial apoptotic pathways in the dorsal horn of the spinal cord is critical in CCI-induced neuropathic pain. The inhibitory role of HBO in GABAergic neuron apoptosis suppresses ongoing neuropathic pain.

Review Meta AnalysisTranscutaneous electrical nerve stimulation (TENS) for neuropathic pain in adults.
Neuropathic pain, which is due to nerve disease or damage, represents a significant burden on people and society. It can be particularly unpleasant and achieving adequate symptom control can be difficult. Non-pharmacological methods of treatment are often employed by people with neuropathic pain and may include transcutaneous electrical nerve stimulation (TENS). This review supersedes one Cochrane Review 'Transcutaneous electrical nerve stimulation (TENS) for chronic pain' (Nnoaham 2014) and one withdrawn protocol 'Transcutaneous electrical nerve stimulation (TENS) for neuropathic pain in adults' (Claydon 2014). This review replaces the original protocol for neuropathic pain that was withdrawn. ⋯ In this review, we reported on the comparison between TENS and sham TENS. The quality of the evidence was very low meaning we were unable to confidently state whether TENS is effective for pain control in people with neuropathic pain. The very low quality of evidence means we have very limited confidence in the effect estimate reported; the true effect is likely to be substantially different. We make recommendations with respect to future TENS study designs which may meaningfully reduce the uncertainty relating to the effectiveness of this treatment modality.

External nasal neuralgia is a rare syndrome of atypical facial pain for which there is limited reports in the scientific literature. We aim to review diagnosis and provide an update on treatments for this rare condition. ⋯ Etiology has been documented as post-traumatic due to direct trauma to the nose area and in few case reports, idiopathic. Sensory innervation of the nose arises from the ophthalmic and maxillary divisions of the trigeminal nerve. Direct injury to the nerve appears to be the etiology of post-traumatic external nasal neuralgia. Pathophysiology for idiopathic nasal neuralgia is poorly understood but it appears to be of a central etiology given lack of response to intranasal anesthetics. Pain can be episodic with episodes of tingling sensation lasting up to 30 min, two to three times per day, but for some patients it can be constant bruised sensation of mild to moderate pain. Diagnostic workup including magnetic resonance imaging of brain and computerized tomography of the sinuses are usually negative, but there have been few cases of a nasal contact point. Routine blood work including erythrocyte sedimentation rate is negative. Treatment for this rare condition is varied with very few patients responding to tricyclic antidepressants, specifically amitriptyline. Another medication used as prevention is pregabalin with good results as well. Most patients respond to nerve blockade with local anesthetic to the external nasal nerve and sphenopalatine ganglion block and radiofrequency ablation. More reports of this condition need to be published in the scientific literature to assist with proper diagnosis and treatment of this condition.
