Effectiveness and Impact of Capsaicin 8% Patch on Quality of Life in Patients with Lumbosacral Pain: An Open-label Study.
Capsaicin 8% patch (Qutenza™) is mainly used to treat postherpetic neuralgia and HIV-associated neuropathy. Evidence of the efficacy of Qutenza in other forms of neuropathic pain is lacking. ⋯ Lumbosacral pain, peripheral pain, Qutenza, neuropathic pain, capsaicin, patch, quality of life, effectiveness.

Epidural neuroplasty using a Racz catheter has a therapeutic effect. Studies have found no correlation between foraminal stenosis and the outcome of epidural neuroplasty, which is thought to depend on contrast runoff. ⋯ Cervical spinal pain, contrast, contrast runoff, epidural neuroplasty, percutaneous adhesiolysis, Racz catheter.

Trigeminal neuralgia (TN) is a pain appearing in the ophthalmic (V1), maxillary (V2), and mandibular (V3) trigeminal branches. Pharmacologic treatment is the first line for TN; however, many patients prefer to receive minimally invasive treatment rather than medicine because of intolerable side effects. Thermocoagulation radiofrequency (TRF) is a minimally invasive treatment that has been shown to effectively treat the maxillary (V2) and mandibular (V3) divisions, but the safety of TRF treatment of the ophthalmic (V1) division has been controversial. ⋯ Thermocoagulation radiofrequency, pulsed radiofrequency, trigeminal neuralgia, ophthalmic division, trigeminal ganglion, pain, numbness, corneal reflex.

Trigeminal neuralgia (TN) is characterized by paroxysmal pain attacks affecting the somatosensory distributions of the trigeminal nerve. It is thought to be associated with a neurovascular conflict most frequently, but pathomechanisms have not been fully elucidated. In general, no sensory deficit is found in routine clinical examination. There is limited data available, however, showing subtle subclinical sensory deficits upon extensive testing. ⋯ Quantitative sensory testing, trigeminal neuralgia, facial pain, neuropathic pain, microvascular decompression, cranial nerve.
