Pulsed radiofrequency (PRF) is a treatment where an intermittent electrical pulse is applied to a painful nerve. CASE REPORT: Twelve patients who reported odontogenic were enrolled. After a positive anesthetic block test at the affected nerve, a PRF procedure was performed. After the procedure, patients were asked to report the degree of tolerability of the procedure, and each patient was reevaluated after one and 6 months in terms of overall satisfaction, reduction of pain, and number of attacks. A total of 18 procedures were performed over 12 patients; 8 patients reported significant clinical improvement . Maximum and mean self-reported pain ratings decreased significantly at both the one- and 6-month follow-ups. CONCLUSION: The use of PRF in treating odontogenic pain appears to show promising results: it is feasible, safe, and associated with little discomfort for the patient.

Priapism may occur as a rare complication following intrathecal narcotic administration.

Following an intrathecal injection of a bolus dose of 100 mcg of morphine, the patient noted the development of an erection lasting 8 hours. A diagnosis of intrathecal morphine-induced priapism was made. CONCLUSION: This report presents the first case in the literature of priapism induced by noncontinuous intrathecal morphine injection in the context of an intrathecal pump trial. A specific mechanism has not yet been defined; however, we believe multiple factors play a role in the body’s response to morphine.

CASE REPORT: A 46-year-old man was urgently treated with a self-expanding stent for idiopathic right carotid artery dissection. However, the patient complained of moderate oppressive pain in the right orbit and forehead immediately after stent placement. Further examination revealed a right eye miosis and right ptosis. No anhidrosis was noted. A diagnosis of Raeder’s syndrome was made based on partial Horner’s syndrome and pain in the first branch of the trigeminal nerve. We noticed that he had hypertension and started antihypertensive medication. After starting the antihypertensive medication, his blood pressure stabilized, and his periorbital pain disappeared dramatically as his blood pressure fell. However, Horner’s symptoms (miosis and ipsilateral ptosis) were still present. CONCLUSION: We experienced a case of Raeder’s syndrome that occurred after stenting of the carotid artery. Neuralgia improved by treatment of hypertension. It should be noted that the paratrigeminal neuralgia of Raeder’s syndrome after carotid stenting can be caused by hypertension.

The case report highlights the need for multidisciplinary education on regional nerve blockade in pediatric palliative medicine. CASE REPORT: The patient was a 5-year-old girl with relapsed metastatic Wilms tumor who presented with recurring malignant pleural effusion, necessitating chest tube insertion. She received a thoracic ESB via catheter to successfully manage uncontrolled pain. Radiation was needed, but radiation providers refused to continue ESB treatment, erroneously citing possible interactions between ESB and radiation therapy. The catheter was removed, and the patient suffered from complications before passing away. CONCLUSION: Interdisciplinary education on regional nerve blockade in pediatrics is imperative to prevent premature removal of anesthetic catheters during treatment, thereby causing unnecessary pain after risk of placement is undertaken. Further, we propose that the ESB is feasible for palliative pain management despite patient age and size.

Despite a number of treatment options, patients with CRPS often suffer from significant impairment and unsatisfactory pain relief. An option rarely considered in managing this condition is amputation due to concerns of pain recurrence or disease progression. CASE REPORT: A 50-year-old man with a history of refractory CRPS on high-dose opioids (over 400 morphine daily equivalents) presented with a request to consider amputation. After extensive interdisciplinary discussion, it was decided to proceed with amputation resulting in successful resolution of his CRPS symptoms with aggressive peri- and postoperative ketamine infusions and a comprehensive therapy program. The patient is now 6 years post amputation and denies phantom limb pain or the spread of CRPS to other limbs. He was subsequently tapered off all opioid medication and has only needed the occasional acetaminophen for pain.

Neuromodulation technology that does not include implantable pulse generators (IPGs) but a 4- or 8-contact electrode array with embedded electronics and a small, externally worn rechargeable transmitter reduces the complications related to the implant of an IPG. PNS has traditionally been performed with a tonic stimulation protocol. This case series describes a wireless PNS device at subthreshold frequencies for the treatment of neuropathic pain of peripheral nerve origins. CASE REPORT: No adverse events were reported, and no complications were encountered during implantation. All patients reported more than 50% pain relief during the one-week trial period, sustained pain relief with various placements and number of electrodes, and an important improvement in quality of life and sleep. Mean VAS scores decreased 78% at one month (n = 11) and remained stable at 6 months with 91% reduction (n = 5) and 76% reduction (n = 1) at 12 months. Mean PGIC at 6 months was 7 of 7. CONCLUSION: Percutaneous placement of an externally powered neurostimulation device adjacent to the affected peripheral nerve(s) is an effective, minimally invasive, and reversible method of pain control in patients with neuropathic pain. PNS using subthreshold frequencies effectively controls neuropathic pain from multiple peripheral nerve targets.
