Autonomic Dysfunction May Distinguish Posttraumatic Headache Autonomic Dysfunction May Distinguish Posttraumatic Headache
Patients with posttraumatic headache often present with a similar phenotype as migraineurs, but new research suggests autonomic dysfunction may help tell them apart.Medscape Medical News
Authors: Hoffmann J, May A Abstract Introduction Neuromodulation techniques play an increasing role in the treatment of primary headaches. While initially reserved for refractory cases they are now increasingly taken into consideration in earlier treatment phases and in non-refractory situations. One of the main reasons of this paradigm shift is that most neuromodulation techniques are better tolerated as compared to the majority of pharmacological approaches. However, these techniques have their limitations that should be considered. Areas covered The review provides an overview of the available techniques and their ...
ConclusionThis study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.ResumoIntroduçãoA cefaleia por ponto de contato da mucosa é uma dor direcionada que surge do contato entre o septo nasal e a parede nasal lateral. Evidências corroboram o papel da substância P na cefaleia de contato, de tal forma que a liberação da mesma a partir de terminações nervosas sensoriais possa causar inflamaçã...
A pulmonary arteriovenous malformation (PAVM) is an anomalous connection between a pulmonary artery and a pulmonary vein that lacks a capillary bed. The most common symptoms of PAVM are dyspnea, exercise intolerance, migraine, stroke or transient ischemic attack, and lung hemorrhage. The treatment of choice is transcatheter embolization with the most common embolic devices being coils (multiple manufacturers) or Amplatzer plugs (AVP) (St. Jude Medical, Plymouth, MN) to occlude the malformation. The newest embolic device for PAVM occlusion is the microvascular plug (MVP) (Micro Vascular Plug System, Medtronic, Minneapolis, MN).
Numerous studies conclude sphenopalatine ganglion blockade (SPGB) with local anesthetic provides effective treatment for cephalalgias with few adverse events. The purpose of this study was to demonstrate safety and efficacy of SPGBs.
This study aimed to determine the efficacy of lidocaine versus bupivacaine when performing an intranasal SPG block for the treatment of headache and facial pain.

Conclusions: Treatments used to manage primary headache disorders may be effective in the management of IIH-associated headache, although none have been specifically studied in this condition. Results: Recommendations provided consider a holistic approach to the problem based on existing guidelines and clinical experience.
Background: Photophobia is commonly associated with migraine, meningitis, concussion, and a variety of ocular diseases. Advances in our ability to trace multiple brain pathways through which light information is processed have paved the way to a better understanding of the neurobiology of photophobia and the complexity of the symptoms triggered by light. Purpose: The purpose of this review is to summarize recent anatomical and physiological studies on the neurobiology of photophobia with emphasis on migraine. Recent Findings: Observations made in blind and seeing migraine patients, and in a variety of animal models...
Abstract: A 46-year-old woman being treated with warfarin for antiphospholipid antibody syndrome experienced a rise in international normalized ratio (INR) to 5.4 and developed sudden headache and diplopia. Neuro-ophthalmologic examination disclosed a right fourth nerve palsy. Noncontrast computed tomography revealed a subdural hematoma layered along the right tentorium cerebelli, directly in the path of the nerve. With normalization of the INR, the palsy markedly improved over subsequent weeks. This is a unique case of a nontraumatic subdural hematoma causing a fourth nerve palsy.
This study has shown that 500 mg magnesium oxide appears to be effective in migraine prophylaxis similar to valproate sodium without significant adverse effect.
