Review Case ReportsThe Diagnosis and Management of Posttraumatic Headache with Associated Painful Cranial Neuralgias: a Review and Case Series.
Cranial neuralgias are common in the setting of posttraumatic headache. They may exacerbate underlying primary headache disorders and therefore may be overlooked in clinical practice. Frequently, cranial neuralgias generate neuropathic symptoms such as lancinating pain and sensory dysesthesias. Cranial neuralgias are identified based on a clinical history of focal neuropathic pain and physical exam findings including tenderness with palpation and percussion, at times eliciting radiating pain or paresthesias in the corresponding sensory nerve distribution. ⋯ Two patients presented with headaches that met criteria for posttraumatic headache, but their history and physical examination suggested the presence of a focal painful cranial neuralgia. One patient was diagnosed with auriculotemporal neuralgia, which was exquisitely responsive to an auriculotemporal nerve block. The second patient was diagnosed with supratrochlear neuralgia, which was effectively treated with a supratrochlear nerve block. In both cases, adequate treatment of the painful cranial neuralgia resulted in significant improvement of the baseline PTH. Painful cranial neuralgias frequently occur within the clinical spectrum of posttraumatic headache, but are often undiagnosed. Treatment options for painful cranial neuralgias are often different than those traditionally employed for posttraumatic headache without cranial neuralgias, which can include peripheral nerve blockade, neuropathic medications, and in refractory cases, peripheral nerve decompression surgery.

Transverse myelitis (TM) is a spinal cord inflammatory myelopathy that causes motor/sensory loss and urinary retention below the level of the affected spinal cord. Although a few case reports have described the control of neuropathic pain in patients with TM via spinal cord stimulation, no documented case regarding the control of severe allodynia following TM via intrathecal pump has been described. ⋯ Neuropathic pain due to Sjögren's syndrome-related TM could be controlled effectively using the intrathecal morphine pump.

Generator site pain is a relatively common phenomenon in patients undergoing spinal cord stimulation (SCS) that complicates management and effective pain relief. This pain may be managed conservatively, with repositioning of the battery and, in some cases, with explant. Here we explore our experience with management of generator site pain ("pocket pain") in a large single-center study. ⋯ In our institutional experience, pocket pain was inadequately managed with conservative treatments. Being female and having SCS filed under WC increased risk of pocket pain. Future work will explore the nuances in device placement based on body shape and manual activity responsibilities.

To ensure an adequate pain therapy with high patient adherence, it is necessary to know and consider patient preferences. A discrete choice experiment was used to obtain patients' preferences regarding treatment with systemic or topical pain medication. Patients with peripheral neuropathic pain (pNP) were recruited in two pain-focused practices in Germany. ⋯ The impairment of sleep quality was also significant but less important (1.556 [1.346 to 1.798]). Local side effects were more likely to be accepted than systemic side effects. The risk of sexual dysfunction as a side effect of treatment is very important for patients, although it has received little attention in the literature.

Complications and Effects of Dorsal Root Ganglion Stimulation in the Treatment of Chronic Neuropathic Pain: A Nationwide Cohort Study in Denmark.
Dorsal root ganglion (DRG) stimulation is a novel treatment of chronic neuropathic pain and has been shown to be efficacious across several case reports and randomized trials. However, long-term follow-up is limited, as are reports of complication rates. This study presents efficacy and complications for patients treated with DRG stimulation. ⋯ This study suggests a significant, clinically relevant effect of DRG stimulation on neuropathic pain, but also demonstrates substantial problems with maintenance and revision of currently available systems. Consequently, treatment with equipment marketed specifically for DRG stimulation is currently paused in Denmark.
