Auriculotemporal neuralgia (ATN) is an infrequent syndrome consisting in strictly unilateral pain in the temporal region associated with nerve tenderness, which can be successfully treated with anesthetic blockade. We analysed clinical characteristics and treatment response in a series of eight patients. ⋯ ATN is uncommon in headache units. Gabapentin is a good alternative therapeutic option to anesthetic blockade.

Stellate Ganglion Block for Debilitating Photophobia Secondary to Trigeminal, Postherpetic Neuralgia.
The primary objective of this case report was to demonstrate the therapeutic benefit of stellate ganglion block in trigeminal postherpetic neuralgia. ⋯ The patient demonstrated significant reduction in her VAS pain score and improved functional capacity for approximately 6 months after the intervention. This case report provides evidence that sympathectomy via a stellate ganglion block can treat photophobia secondary to postherpetic neuralgia in the V1 distribution.

Case ReportsSpinal Cord Stimulation for Treatment of Neuropathic Pain Associated With Erythromelalgia.
Erythromelalgia is a rare disorder associated with neuropathic pain that commonly affects the lower extremities. This pain is often refractory to multimodal treatment. Both pharmacologic management and interventional anesthetic blocks have been used with varying and often limited success. To date, little experience has been gained with the use of spinal cord stimulation in treating pain associated with erythromelalgia. ⋯ Spinal cord stimulation may be a promising treatment of neuropathic pain associated with erythromelalgia.

The efficacy of epidural spinal cord stimulation on chronic neuropathic pain due to failed back surgery syndrome or nerve root lesions is well reported. There is even literature reporting the effects of spinal cord stimulation in controlling peripheral vascular lesions as in peripheral arteriopathies or diabetic neuropathies and in complex regional pain syndrome type II. This is probably due to an effect of epidural spinal cord stimulation, mainly on the parasympathetic nervous system. ⋯ This is the first case report of severe chronic pain syndrome due to a widespread lymphangioma successfully treated by means of epidural spinal cord stimulation.

Both early life stress and neuropathic pain induce morphological and functional abnormalities of the nervous system that are associated with emotional regulation. In our previous study, early life stress enhanced nerve injury-induced hyperalgesia in adult male and female mice. In the present study, using phosphorylated extracellular signal-regulated kinase (p-ERK) as a marker of neuronal activation, we examined the effect of early life stress on neuronal function following partial sciatic nerve ligation (PSL). ⋯ The present data suggest that early life stress sex-dependently and site-specifically increases neuronal activity in the brain. In addition, increased neuronal activity in multiplebrain regions of mice subjected to early life stress may enhance hyperalgesia after nerve injury. WHAT DOES THIS STUDY ADD?: Maternal separation and social isolation (MSSI) increased p-ERK in the paraventricular nucleus (PVN) and amygdala of male mice. MSSI increased p-ERK in the medial prefrontal cortex and nucleus accumbens of female mice. Neuropathic pain increased p-ERK in the PVN and amygdala of female MSSI mice.
