Headache is an important diagnostic element in pheochromocytoma and it may characterize a body reaction to pathological hormonal oscillations. We observed the pheochromocytoma instability in 20 patients during arterial hypertension and tried to correlate with headache. We found that isolate hypertension is not the only factor in headache pathogenesis. It is possible that changes in catecholamines, adrenomedullin and other neuropeptides may cause some of these symptoms.

Introduction: Central Post-Stroke Pain (CPSP) is a debilitating condition with a significant prevalence in stroke survivors. Set apart by its refractory to treatment neuropathic pain, it appears to arise from lesions in the spino-thalamo-cortical pathways, particularly in the thalamus. Despite advances in neuroimaging techniques, the pathophysiology of CPSP remains poorly understood, with limited diagnostic criteria and therapeutic approaches.

Headache Centre, Department of Advanced Medical and Surgical Sciences, University of Campania "Luigi Vanvitelli", Naples, Italy.
Introduction: When a first anti-CGRP monoclonal antibody (anti-CGRP mAb) fails, switching to a different anti-CGRP mAb is an option often considered, despite this approach is not yet systemically studied.
Methods: We present the findings of a systematic review conducted according to the PRISMA recommendations on published studies - of any design - investigating the clinical outcomes after switching for any reason to different anti-CGRP mAbs.
Results: The literature search retrieved 76 records, while 19 papers were eventually reviewed.
Performance of the CT-Guided C1-C2 Facet (Lateral Atlantoaxial Joint) Injection.
AJNR Am J Neuroradiol
January 2025
University of Utah Department of Radiology and Imaging Sciences (D.A., T.A.H., L.M.S., M.E.P.), Salt Lake City, Utah.
CT-guided C1-C2 facet joint injections are a valuable tool for managing cervicogenic headaches caused by degenerative and inflammatory conditions of the atlantoaxial joint. This video article presents the procedural technique for a CT-guided C1-C2 facet joint injection in a patient with left-sided cervicogenic headache. Despite concerns regarding potential complications such as vascular injury to the vertebral artery and nerve injury to the C2 dorsal root ganglion, careful anatomic planning and imaging guidance allows safe and effective treatment.

Curr Pain Headache Rep
January 2025
Department of Physical Medicine & Rehabilitation, Temple University Hospital, Philadelphia, PA, USA.
Objectives: This study aims to review the societal, economic, and racial factors that impact the usage of spinal cord stimulation for chronic pain. Our working hypothesis is that patients of ethnic minority groups or of lower socioeconomic status (SES) status may have lower implantation rates and usage of spinal cord stimulation (SCS).
Materials And Methods: Our study sourced publications from PubMed, Embase, and Cochrane Library on December 21st, 2023 for SCS for the purposes of pain management.
