ABSTRACT
Erythromelalgia is a rare disorder characterized by episodic burning pain with redness and warmth of the extremities. Topical and systemic medications are the mainstay of management. We reviewed the published evidence for using procedural interventions to manage erythromelalgia, including their proposed mechanism of action and possible adverse effects, and included information in this review on epidural infusion, sympathetic ganglion block, sympathectomy, pulsed radiofrequency, spinal cord stimulation, dorsal root ganglion stimulation, brain stimulation, transcranial magnetic stimulation, and botulinum toxin injections. Both successful and unsuccessful outcomes have been reported. Although these procedural interventions extend the therapeutic options for erythromelalgia, the evidence for their use is limited. Case reports and small case series comprise most of the evidence. Based on our review, a multidisciplinary approach to management may be needed for patients with erythromelalgia.
ABSTRACT
INTRODUCTION: Dermatologic complaints are a common reason for emergency department visits. METHODS: Retrospective chart review from 1 January 2015 to 31 December 2019. Patients in the Mayo Clinic Emergency Department receiving dermatology consultation were included. RESULTS: Dermatitis (24.7%, n = 113), infection (20.4%, n = 93), and drug reaction (10.3%, n = 47) accounted for the majority of diagnoses. Emergency department providers often provide no diagnosis (38%) or a differential diagnosis (22%), and dermatology consultation frequently alters diagnosis (46%) and treatment (83%). Patients receiving in-person consultations are admitted more frequently than those receiving teledermatology consultations (40% vs. 16%, p < 0.001). Primary diagnostic concordance with subsequent dermatology evaluation is high for in-person (94%) and teledermatology (88%) consultations. DISCUSSION: This is the largest study of emergency department dermatology consultations in the United States and the first to compare in-person and teledermatology emergency department consultation utilization in clinical practice. These modalities are utilized in a complementary fashion at our institution, with severe dermatologic diagnoses seen in-person. The valuable role of emergency department dermatologists is highlighted by frequent changes to diagnosis and treatment plans that result from dermatology consultation. Furthermore, our data suggest that teledermatology is an effective modality with the potential to expand access to dermatologic expertise in the emergency department setting.
