[PMID: 38957119 DOI: 10.1111/head.14769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/16/2024] [Accepted: 04/21/2024] [Indexed: 07/04/2024]
Abstract
OBJECTIVES Identify how the American Headache Society (AHS) membership manages status migrainosus (SM) among outpatients. BACKGROUND SM is defined as a debilitating migraine attack lasting more than 72 h. There is no standard of care for SM, including whether a 72-h duration is required before the attack can be treated as SM. METHODS The Refractory Headache Special Interest Group from AHS developed a four-question survey distributed to AHS members enquiring (1) whether they treat severe refractory migraine attacks the same as SM regardless of duration, (2) what their first step in SM management is, (3) what the top three medications they use for SM are, and (4) whether they are United Council for Neurologic Subspecialties (UCNS) certified. The survey was conducted in January 2022. Descriptive statistical analyses were performed. RESULTS Responses were received from 196 of 1859 (10.5%) AHS members; 64.3% were UCNS certified in headache management. Respondents treated 69.4% (136/196) of patients with a severe refractory migraine attack as SM before the 72-h period had elapsed. Most (76.0%, 149/196) chose "treat remotely using outpatient medications at home" as the first step, 11.2% (22/196) preferred procedures, 6.1% (12/196) favored an infusion center, 6.1% (12/196) sent patients to the emergency department (ED) or urgent care, and 0.5% (1/196) preferred direct hospital admission. The top five preferred medications were as follows: (1) corticosteroids (71.4%, 140/196), (2) nonsteroidal anti-inflammatory drugs (NSAIDs) (50.1%, 99/196), (3) neuroleptics (46.9%, 92/196), (4) triptans (30.6%, 60/196), and (5) dihydroergotamine (DHE) (21.4%, 42/196). CONCLUSIONS Healthcare professionals with expertise in headache medicine typically treated severe migraine attacks early and did not wait 72 h to fulfill the diagnostic criteria for SM. Outpatient management with one or more medications for home use was preferred by most respondents; few opted for ED referrals. Finally, corticosteroids, NSAIDs, neuroleptics, triptans, and DHE were the top five preferred treatments for home SM management.

Abstract
PURPOSE OF REVIEW Pain is a complex phenomenon that affects millions of individuals worldwide and poses a significant burden on public health. While pain management typically focuses on pharmacological and physical interventions, emerging research suggests that nutrition plays a crucial role in pain modulation. This narrative review aims to explore the relationship between nutrition and pain, providing a comprehensive overview of recent literature. The review covers various dietary factors, including macronutrients, micronutrients, dietary patterns, and specific dietary interventions. Additionally, the potential mechanisms underlying the impact of nutrition on pain are discussed. The findings highlight the potential for dietary interventions to complement traditional pain management approaches and provide valuable insights for future research and clinical practice. RECENT FINDINGS Literature suggested the impact of healthy nutrition on improvement in pain and that certain types of food may increase and worsen different pain conditions. Nutrition plays an important role in modulating pain. It is important to counsel patients in pain on best diet for their pain condition to alleviate pain. Our article summarizes very well the issue of nutrition and pain and provides a guide to all practitioners caring for patients with chronic pain.

Testing the Role of Glutamate NMDA Receptors in Peripheral Trigeminal Nociception Implicated in Migraine Pain. Int J Mol Sci 2022; 23:ijms23031529. [PMID: 35163452 PMCID: PMC8835926 DOI: 10.3390/ijms23031529] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/20/2022] [Accepted: 01/26/2022] [Indexed: 01/18/2023] Open
Abstract
The pro-nociceptive role of glutamate in the CNS in migraine pathophysiology is well established. Glutamate, released from trigeminal afferents, activates second order nociceptive neurons in the brainstem. However, the function of peripheral glutamate receptors in the trigeminovascular system suggested as the origin site for migraine pain, is less known. In the current project, we used calcium imaging and patch clamp recordings from trigeminal ganglion (TG) neurons, immunolabelling, CGRP assay and direct electrophysiological recordings from rat meningeal afferents to investigate the role of glutamate in trigeminal nociception. Glutamate, aspartate, and, to a lesser extent, NMDA under free-magnesium conditions, evoked calcium transients in a fraction of isolated TG neurons, indicating functional expression of NMDA receptors. The fraction of NMDA sensitive neurons was increased by the migraine mediator CGRP. NMDA also activated slowly desensitizing currents in 37% of TG neurons. However, neither glutamate nor NMDA changed the level of extracellular CGRP. TG neurons expressed both GluN2A and GluN2B subunits of NMDA receptors. In addition, after removal of magnesium, NMDA activated persistent spiking activity in a fraction of trigeminal nerve fibers in meninges. Thus, glutamate activates NMDA receptors in somas of TG neurons and their meningeal nerve terminals in magnesium-dependent manner. These findings suggest that peripherally released glutamate can promote excitation of meningeal afferents implicated in generation of migraine pain in conditions of inherited or acquired reduced magnesium blockage of NMDA channels and support the usage of magnesium supplements in migraine.

Abstract
CONTEXT The International Association for the Study of Pain (IASP) defines chronic pain as pain that persists or recurs for longer than 3 months. Chronic pain has a significant global disease burden with profound effects on health, quality of life, and socioeconomic costs. EVIDENCE ACQUISITION Narrative review. RESULTS There are several treatment options, including pharmacological therapy, physical rehabilitation, psychological therapies, and surgical interventions, for chronic pain management. Magnesium has been FDA-approved for several indications including hypomagnesemia, arrhythmia, prevention of seizures in eclampsia/preeclampsia, and constipation. Magnesium has been used for numerous off-label uses, notably for acute and chronic pain management. The mechanism of magnesium in pain management is primarily through its action as a voltage-gated antagonist of NMDA receptors, which are involved in pain transduction. CONCLUSIONS This narrative review will focus on the current evidence and data surrounding the utilization of magnesium as a treatment option for chronic pain.

Abstract
Status migrainosus (SM) is a subtype of migraine defined by migraine lasting >72 hours and is difficult to treat in clinical practice. Magnesium is commonly used in the treatment of migraine. We conducted a retrospective cohort study to determine if length of admission was associated with IV magnesium therapy in patients with SM. We reviewed the charts of all patients admitted to a large military treatment facility from October 2013 to December 2018 with the admission diagnosis of migraine. There were 333 patients that were reviewed and 141 met the inclusion criteria. Nearly half of patients received IV magnesium therapy with routine care (46.8%, n = 66). IV magnesium therapy was not associated with length of admission (58 hours (IQR 25.5, 86) compared to 42 hours (IQR 25.5, 80.5) respectively, p = 0.47). Of the cases without Neurology consultation, patients who received magnesium therapy (n = 5) had numerically shorter admission but this difference did not meet statistical significance (n = 12) (17 hours (IQR 13.75, 31.25) versus 24.5 hours (IQR 15.25, 58.75), p = 0.0534). This study contributes to the limited pool of available data on the treatment of SM. Prospective research is needed to study magnesium therapy in patients with prolonged migraine.

Abstract
Magnesium as an enzymatic activator is essential for various physiological functions such as cell cycle, metabolic regulation, muscle contraction, and vasomotor tone. A growing body of evidence supports that magnesium supplementation (mainly magnesium sulfate and magnesium oxide) prevents or treats various types of disorders or diseases related to respiratory system, reproductive system, nervous system, digestive system, and cardiovascular system as well as kidney injury, diabetes and cancer. The ongoing pandemic coronavirus disease 19 (COVID-19) characterized by respiratory tract symptoms with different degrees of important organ and tissue damages has attracted global attention. Particularly, effective drugs are still lacking in the COVID-19 therapy. In this review, we find and summarize the effectiveness of magnesium supplementation on the disorders or diseases, and provide a reference to the possibility of magnesium supplementation for supportive treatment in patients with COVID-19.

Abstract
PURPOSE OF REVIEW This article reviews treatment options for patients presenting with headache in the emergency department (ED) and for inpatients, including red flags and status migrainosus (SM). RECENT FINDINGS Most patients presenting with headache in the ED will have migraine, but red flags must be reviewed to rule out secondary headaches. SM refractory to home treatment is a common reason for ED presentation or inpatient admission, but high-quality treatment evidence is lacking. Common treatments include intravenous fluids, anti-dopaminergic agents with diphenhydramine, steroids, divalproex, nonsteroidal anti-inflammatory drugs, intravenous dihydroergotamine, and nerve blocks. Other therapies (e.g., ketamine and lidocaine) are used with limited or inconsistent evidence. There is evidence for inpatient behavioral management therapy. This article details red flags to review in the workup of headache presentation in the ED and provides a step-wise approach to ED and inpatient management. However, more studies are needed to better optimize care.

Abstract
INTRODUCTION Non-traumatic headaches comprise up to 4% of all emergency department (ED) visits. Current practice is moving toward multimodal analgesia regimens that limit narcotic use. OBJECTIVE The objective of this systematic review is to address the following research question: In patients with non-traumatic headaches (Population), does administration of intravenous magnesium sulfate (Intervention) compared to placebo, corticosteroids, dopamine antagonists, ergot alkaloids, non-steroidal anti-inflammatory drugs (NSAIDs), triptans, or usual care result in better pain control, lower rate of recurrence at 24 hours, lower requirements for rescue analgesia, and less adverse medication effects (Outcomes)? METHODS Scholarly databases and relevant bibliographies were searched, as were clinical trial registries and relevant conference proceedings to limit publication bias. Studies were not limited by date, language, or publication status. Inclusion criteria were: (1) randomized clinical trial (RCT), (2) patients age ≥18 years, (3) non-traumatic headache, (4) patients treated in ED or an outpatient acute care treatment center, and (5) magnesium sulfate administered intravenously (IV). Eligible comparison groups included: placebo, conventional therapy, dopamine antagonist, NSAID, corticosteroid, ergot alkaloid, or triptans. RESULTS Out of 4018 identified references, 7 RCTs (545 participants) that treated migraine headaches (n = 6) and benign non-traumatic headaches (n = 1) met inclusion criteria. Pain intensity was improved with magnesium sulfate vs comparators at 60-120 minutes, but not at earlier time points. Result for the endpoint of pain reduction by 50% were conflicting as 3 studies reported that headache was improved, unchanged, and less with magnesium sulfate. Complete pain relief was improved with magnesium sulfate in 1 study, and in the migraine with aura (MA) subgroup in another. The need for rescue analgesia at any point was improved with magnesium sulfate in 1 study, and in the MA subgroup in another. Twenty-four-hour headache recurrence was improved with magnesium sulfate in 1 study, but unchanged in a second. The intended meta-analysis was not performed due to the clinical heterogeneity among studies. CONCLUSION While we cannot draw a firm conclusion on the efficacy or benefit of intravenous magnesium sulfate in the treatment of acute non-traumatic headaches, the existing evidence indicates potential benefits in pain control beyond 1 hour, aura duration, and need for rescue analgesia.

Abstract
Migraine is a major public health problem afflicting approximately 10% of the general population and is a leading cause of disability worldwide, yet our understanding of the basis mechanisms of migraine remains incomplete. About a third of migraine patients have attacks with aura, consisting of transient neurological symptoms that precede or accompany headache, or occur without headache. For patients, aura symptoms are alarming and may be transiently disabling. For clinicians and scientists, aura represents an intriguing neurophysiological event that may provide important insight into basic mechanisms of migraine. Several observations point toward important differences between migraine with and without aura. Compared with migraine without aura, migraine with aura has different heritability, greater association with different conditions including stroke, different alterations of brain structure and function as revealed by imaging studies. A number of studies also indicate that migraine with aura may respond differently to acute and preventive therapies as compared to migraine without aura. The purpose of this review is to provide an overview of these differences in treatment responses, and to discuss the possibility of different therapeutic strategies for migraine with vs. without aura.
