Case Reports
Unusual presentations of thoracic disc herniation treated by thoracic epidural block: Case reports.
Herniation of the thoracic intervertebral disc (HTD) is a rare disease that accounts for <1% of all disc herniations. Physicians may make diagnostic errors due to the variable clinical features and limited experience of HTD. In this report, we present 2 unusual cases of HTD. ⋯ Multilevel HTD of the mid- to lower-thoracic spine may present as abdominal bulging with atrophy of the abdominal wall muscles. We also report another case of concomitant symptomatic thoracic radiculopathy from HTD and postherpetic neuralgia at the adjacent level. Thoracic transforaminal epidural block may be considered a conservative therapeutic approach for HTD.

Meta Analysis
Nerve pathology and neuropathic pain after whiplash injury: a systematic review and meta-analysis.
There is no clear understanding of the mechanisms causing persistent pain in patients with whiplash-associated disorder (WAD). The aim of this systematic review was to assess the evidence for nerve pathology and neuropathic pain in patients with WAD. EMBASE, PubMed, CINAHL (EBSCO), and MEDLINE were searched from inception to September 1, 2020. ⋯ Similar sensory dysfunction and nerve mechanosensitivity was seen in WAD grade II, which contradicts its traditional definition of absent nerve involvement. Our findings strongly suggest a subset of patients with WAD demonstrate signs of peripheral nerve pathology and neuropathic pain. Although there was heterogeneity among some studies, typical WAD classifications may need to be reconsidered and include detailed clinical assessments for nerve integrity.

Thermic rhizolysis is a reliable therapy for pharmaco-resistant trigeminal neuralgia (TN). Temperature, duration of electrocautery and needle location can influence the efficacy and complications of the therapy. ⋯ We have adapted the technique of radiofrequency rhizolysis for TN. Our procedure allows individual peroperative adaptation of the parameters of thermocoagulation, according to the specific position of the electrode during rhizolysis. Preliminary results on a series of 22 patients have shown promising results.
