Abstract
PURPOSE Although different forms of lidocaine are used for migraine attack headaches, the effect of intravenous lidocaine is still limited. This study aimed to investigate the effects of intravenous lidocaine infusion for the treatment of migraine attack headaches. METHODS A hundred patients with migraine attacks, aged between 18 and 65, were randomly divided into two groups. The lidocaine group (n = 50) received a 1.5 mg/kg lidocaine bolus and a 1 mg/kg infusion (first 30 min), followed by a 0.5 mg/kg infusion for a further 30 min intravenously. The non-steroidal anti-inflammatory drug (NSAID) group (n = 50) received 50 mg dexketoprofen trometamol and saline at the same volume as the lidocaine at the same time intervals intravenously. The Visual Analog Scale (VAS) pain scores, additional analgesia requirement, side effects, and revisits to the emergency department were recorded. RESULTS The VAS score was significantly lower in the lidocaine group than in the NSAID group for the first 20th and 30th minutes (p = 0.014 and p = 0.024, respectively). There was no difference between the VAS scores for the remaining evaluation times (p > 0.05). In terms of secondary outcomes, rescue medication requirement was not different between the two groups at both the 60th and 90th minutes (p > 0.05). However, the number of patients revisiting ED within 48-72 h was statistically less in the lidocaine group than in the NSAID group (1/50 vs. 8/50; p = 0.031). CONCLUSION Intravenous lidocaine may be an alternative treatment method for patients with migraine attack headaches in the emergency department.

Abstract
BACKGROUND The restrictions taken to control the rapid spread of COVID-19 resulted in a sudden, unprecedented change in people's lifestyle, leading to negative consequences on general health. This study aimed to estimate the impact of such changes on migraine severity during 2020 March-May lockdown. METHODS Patients affected by migraine with or without aura, diagnosed by expert physicians, completed a detailed interview comprehensive of: assessment of migraine characteristics; measure of physical activity (PA) levels; measure of the intake frequency of main Italian foods; the Insomnia Severity Index (ISI) questionnaire investigating sleep disorders. RESULTS We included 261 patients with a mean age of 44.5 ± 12.3 years. During social distancing, 72 patients (28%) reported a headache worsening, 86 (33%) an improvement, and 103 (39%) a stable headache frequency. A significant decrease of the PA levels during COVID-19 quarantine in the whole study sample was observed (median total metabolic equivalent task (METs) decreased from 1170 to 510; p < 0.001). Additionally, a significant difference was reported on median ISI scores (from 7 to 8; p < 0.001), which were increased in patients who presented a stable or worsening headache. CONCLUSIONS Our study confirmed that the restrictions taken during the pandemic have affected the practice of PA levels and sleep quality in migraine. Hence, PA and sleep quality should be assessed to find strategies for an improvement in quality of life.

Pediatric neurology. 2021;:68-73
Abstract
BACKGROUND A combination of parenteral medications (often referred to as standard combination therapy) is frequently used in the treatment of acute migraine in the pediatric emergency department (PED). The primary aim of this study was to evaluate the two-hour, 24-hour, and seven-day impact of one such regimen on pain in children who present to the PED. Standard combination therapy for purposes of our study is defined as a bolus of intravenous saline, and a combination of intravenous ketorolac, prochlorperazine, and diphenhydramine. METHODS This prospective observational study included 120 children between the ages seven and 18 years who presented to the PED with migraine, whose parents could read and understand the consent form in English, and who were treated with standard combination therapy. The primary outcome measure for this study was the change in severity of pain as noted by the child using the Faces Pain Scale-Revised. We analyzed normally distributed continuous variables by mean and standard deviation, whereas non-normally distributed continuous variables are reported by median and interquartile range. RESULTS Nonparametric Friedman testing on the entire cohort (n = 120) noted that there was a statistically significant change in the Faces pain scale from before administration of standard combination therapy to the two-hour, 24-hour, and one-week time point with a reduction in pain score of 87.5%, 100%, and 50%, respectively, at the three time points. CONCLUSIONS This study noted moderate relief of pain after administration of standard combination therapy, which persisted at one-week after administration.

Headache. 2021;(4):603-611
Abstract
OBJECTIVE To compare the efficacy of intravenous chlorpromazine versus intravenous prochlorperazine for the treatment of acute migraine in adults presenting to the emergency department (ED). BACKGROUND Migraine is a common, incapacitating neurological condition. Although chlorpromazine and prochlorperazine are known to be safe, efficacious treatments for migraine, they have never been directly compared. DESIGN We performed a prospective, randomized, double-blind clinical trial at a tertiary hospital in Melbourne, Australia. Adults aged 18-65 years, who presented with migraine, were eligible for recruitment. Sixty-six patients were randomized to either chlorpromazine 12.5 mg or prochlorperazine 12.5 mg, both infused in 500 ml of sodium chloride 0.9% over 30 min. Headache severity score, nausea severity score, and the presence of photophobia and phonophobia were assessed at 0, 30, 60, and 120 min. Adverse effects and the need for rescue therapy were recorded. The primary outcome was a reduction in headache severity score from baseline at 60 min post-commencement of the study medicine infusion. RESULTS Sixty-five patients were included in the analysis. There was a median reduction in headache severity score at 60 min of 3.0 (interquartile range 1.0-4.0) in the chlorpromazine arm versus 2.0 (1.0-4.0) in the prochlorperazine arm (median difference -0.5 (95% confidence interval, -1.9 to 0.9)). We saw no evidence of a difference in secondary outcomes at 30, 60, or 120 min. Side effects were reported in 16/32 (50%) patients in the chlorpromazine group versus 7/33 (21%) in the prochlorperazine group (p = 0.020). Rescue therapy was required in 7/32 (22%) patients in the chlorpromazine group versus 12/33 (36%) in the prochlorperazine group (p = 0.277). CONCLUSIONS Both chlorpromazine and prochlorperazine are efficacious treatments for acute migraine in adult patients presenting to the ED. This trial found no evidence of superiority of either agent over the other. Caution should be used when prescribing these medicines in the borderline hypotensive patient; in that circumstance, prochlorperazine should be preferentially used.

Abstract
OBJECTIVE To study Ramadan's effect on migraine from the start to the end of the month and the tolerability of patients with migraine to fasting. BACKGROUND Fasting is a well-known trigger for migraine. Whether this effect on migraine is the same throughout the whole month, or whether it varies from the first to the last days of the month, has not been studied yet. METHODS A prospective cohort observational study was carried out on persons with migraine who fasted from 24 April to 23 May during Ramadan 2020. Each patient was asked to fill out their headache diary starting from Shaaban (the month before Ramadan) to the end of Ramadan. The Ramadan diary was divided by 10 days each, by which the patient was asked to accurately describe their migraine attacks in terms of frequency, duration, and intensity by using the Visual Analog Scale. Migraine attacks during the first day of fasting were assessed separately. RESULTS A total of 292 known persons with migraine from Egypt completed the study. Their median age was 33 years; 72/292 (24.7%) were male, and 220/292 (75.3%) were female. About 126/236 (53.4%) of the patients had migraine attacks on Ramadan's first day, most of them during fasting. The frequency of migraine attacks was significantly increased in Ramadan (median 4, interquartile range [IQR] 2-7) compared with Shaaban (median 3, IQR 1-6), p = 0.009. The number of attacks was significantly reduced in both the second (median 1, IQR 0-2.25) and the third 10 days of Ramadan (median 1, IQR 1-3) compared with the first 10 days (median 3, IQR 1-5) (p < 0.001 for each). CONCLUSION Ramadan's potential exacerbating effect on the frequency of migraine attacks should be discussed with patients with migraine. This effect appears to be limited to the first 10 days of Ramadan and then subsides with successive days of fasting.

Abstract
OBJECTIVE To evaluate the efficacy and safety of intravenous (IV) Ibuprofen for acute treatment of migraine. BACKGROUND IV nonsteroidal anti-inflammatory drugs (NSAIDs) are an alternative to oral NSAIDs, especially in patients with severe migraine who have emesis or gastroparesis. To date, only three IV NSAIDs (ketorolac, ibuprofen, and meloxicam) are available in the United States for use in moderate and severe pain, but no placebo-controlled trial is available for migraine. We performed a single-center, double-blind, randomized, placebo-controlled pilot study to evaluate the efficacy and safety of IV ibuprofen as an acute treatment of migraine (NCT01230411). METHODS Individuals with episodic migraine were screened at the Jefferson Headache Center. Qualified subjects were treated for migraine attacks within 2-72 h following the headache onset with either 800 mg of IV ibuprofen or placebo in 250 ml saline bolus. Migraine pain intensity (4-point Likert scale) and associated symptoms were assessed at predetermined time points (0.25, 0.5, 1, 1.5, 2, 4, 8, 24 h). The primary endpoint was pain relief at 2 h after infusion. Important secondary endpoints included pain freedom at 2 h, sustained relief over 24 h, use of rescue therapy, and absence of associated symptoms. Adverse events (AEs) were also collected. RESULTS Seventy-four participants were enrolled between 2011 and 2017. Forty-four subjects (female 33/44; 75.0%) with mean (SD) age 41.0 (11.2) 11.2 years came for the treatment. All treated subjects (n = 44) were included in the analysis. Among them, 23 were randomized to receive IV ibuprofen. Both groups were demographically similar except for longer migraine duration (i.e., years lived with disease) in the active treatment than in the placebo group. At 2 h posttreatment, pain relief was found in 74% (17/23) and 48% (10/21) after IV ibuprofen and placebo, respectively (odds ratio [OR] 3.12, 95% CI: 0.88-11.0; p = 0.078). Other secondary endpoints at 2 and 24 h were not significant. The longitudinal repeated-measures analysis within 2 h on ibuprofen treatment showed significant pain relief (OR 2.47, 95% CI 1.08-5.7; p = 0.033) and absence of associated symptoms: photophobia (OR 4.0, 95% CI 1.57-10.3; p = 0.004), phonophobia (OR 3.12, 95% CI 1.16-8.4; p = 0.025), and osmophobia (OR 3.45, 95% CI 1.01-11.8; p = 0.048). AEs were observed in seven subjects in both groups, with arm pain being the most common. No serious AE was reported. CONCLUSION This study did not meet the primary endpoint but showed pain relief and elimination of several associated symptoms within 2 h on repeated-measures analysis. Although limited by small sample size and high placebo response, our results indicate that IV ibuprofen may be a safe and effective option for acute treatment of migraine, but more extensive studies are necessary.

Abstract
BACKGROUND The association of migraine with vascular comorbidities is long-established. The contribution of the "traditional" cardiovascular risk factors to this connection remains unclear. OBJECTIVE To determine-quantify the differences in the serum lipid concentrations between lipid-lowering agents-naïve individuals with migraine and healthy controls (HC). METHODS The study protocol was not preregistered with an online systematic review-protocol registry. A literature search involving MEDLINE, EMBASE, CENTRAL, Google Scholar, and the OpenGrey database was performed. Case-control, cross-sectional, or cohort studies involving HC and participants with migraine (with and without aura regardless of the use of prophylactic treatment) that quantitatively assessed serum low-density lipoprotein cholesterol (LDL-C) (primary index) and/or total cholesterol (TC) and/or high-density lipoprotein cholesterol (HDL-C) and/or triglycerides (TG) (secondary indices) were retrieved. Articles including participants with known dyslipidemia (or under lipid-lowering medications) or with secondary causes of dyslipidemia (aside from the subjectively assessed lifestyle parameters) were excluded. Studies with abstracts and full texts not published in English and articles reporting the implementation of other study designs (reviews, meta-analyses, commentaries, case reports, etc.) were excluded as well. Conference abstracts and English abstracts from studies with full texts not published in English were evaluated as part of the gray literature. Each step of the review process was performed by two investigators independently, and relevant data were abstracted based on standardized extraction forms. Any discrepancies were resolved by a third investigator. RESULTS Seventeen studies (16 case-control and 1 cross-sectional) fulfilled the eligibility criteria. Retrieved articles involved adult participants, principally during the fourth decade of life. Results were compatible with higher LDL-C levels in migraine individuals (1370) than in HC (1215) [12 studies, mean difference (MD) = 10.4 mg/dl, 95% confidence interval (CI) = (1.6, 19.2)]. Similarly, higher TC levels were determined in migraine patients [14 studies, migraine = 1325, HC = 1213, MD = 10.6 mg/dl, 95% CI = (1.8, 19.3)], as were TG levels [15 studies, migraine = 1526, HC = 1262, MD = 11.8 mg/dl, 95% CI = (3.6, 20.0)]. HDL-C concentrations were not different between the two groups [14 studies, migraine = 1488, HC = 1328, MD = -0.4 mg/dl, 95% CI = (-2.2, 1.5)]. Prespecified sensitivity analysis following the exclusion of studies not presenting comparable body mass index values between the groups nullified the significant difference regarding LDL-C levels [MD = 5.3 mg/dl, 95% CI = (-0.1, 10.8)]. Subgroup analyses as well as the direct comparison of migraine with aura and migraine without aura individuals were compatible with no difference regarding lipid concentrations, but only a small fraction of the retrieved studies presented relevant figures. CONCLUSIONS Although our results are of limited generalizability, since most retrieved studies were performed in Turkey (nine studies), TC abnormalities may provide part of the explanation for the unfavorable cardiovascular profile of migraine patients. Lifestyle may be partly or entirely accountable for the determined increased serum TC. Additional studies that will completely address the effect that lifestyle parameters exert on lipid concentrations are required to better capture existing abnormalities.

Retrospective Observational Study on Riboflavin Prophylaxis in Child and Adolescent Migraine.
Das, R, Qubty, W
Pediatric neurology. 2021;:5-8
Abstract
BACKGROUND We evaluated the efficacy of riboflavin in pediatric migraineurs. METHODS A retrospective observational study was performed on 42 patients (aged six to 18 years) with migraine who were evaluated from January to December 2019 at Dell Children's Medical Center in Austin, Texas. Weight-based dosing of riboflavin was recommended for migraine prevention. Descriptive statistics were used to study the population demographics. Nonparametric tests were used for inferential statistics to study the effect of riboflavin on headache frequency, intensity, and duration. RESULTS Patients treated with riboflavin had a significant reduction in headache days per month (frequency) at the first follow-up visit at 2 to 4 months (T1) (11.07 ± 10.52 days) compared with the baseline T0 (21.90 ± 9.85 days); P < 0.001 in regard to the primary outcome in 42 patients (mean age, 13.38 ± 3.38). Mean headache intensity decreased from 8.85 (±6.41; T0) to 2.30 (±2.51; T1); P < 0.001 on a 0 to 10 scale. The headache duration also reduced significantly from 18.23 ± 17.07 hours (T0) to 10.18 ± 10.49 hours (T1); P = 0.001. There was a positive correlation between riboflavin efficacy and reduced use of acute medications (rs = 0.304; P = 0.05). Riboflavin was useful in reducing the frequency and intensity in two patients with new daily persistent headache. CONCLUSIONS Patients treated with riboflavin had a reduction in headache frequency, use of acute medications, and days of school missed. Riboflavin prophylaxis also reduced migraine intensity and duration. Riboflavin is recommended as a safe, inexpensive, and effective nutraceutical in the treatment of pediatric migraine.

A new hypothesis linking oxytocin to menstrual migraine.
Bharadwaj, VN, Porreca, F, Cowan, RP, Kori, S, Silberstein, SD, Yeomans, DC
Headache. 2021;(7):1051-1059
Abstract
OBJECTIVE To highlight the emerging understanding of oxytocin (OT) and oxytocin receptors (OTRs) in modulating menstrual-related migraine (MRM). BACKGROUND MRM is highly debilitating and less responsive to therapy, and attacks are of longer duration than nonmenstrually related migraine. A clear understanding of the mechanisms underlying MRM is lacking. METHODS We present a narrative literature review on the developing understanding of the role of OT and the OTR in MRM. Literature on MRM on PubMed/MEDLINE database including clinical trials and basic science publications was reviewed using specific keywords. RESULTS OT is a cyclically released hypothalamic hormone/neurotransmitter that binds to the OTR resulting in inhibition of trigeminal neuronal excitability that can promote migraine pain including that of MRM. Estrogen regulates OT release as well as expression of the OTR. Coincident with menstruation, levels of both estrogen and OT decrease. Additionally, other serum biochemical factors, including magnesium and cholesterol, which positively modulate the affinity of OT for OTRs, both decrease during menstruation. Thus, during menstruation, multiple menstrually associated factors may lead to decreased circulating OT levels, decreased OT affinity for OTR, and decreased expression of the trigeminal OTR. Consistent with the view of migraine as a threshold disorder, these events may collectively result in decreased inhibition promoting lower thresholds for activation of meningeal trigeminal nociceptors and increasing the likelihood of an MRM attack. CONCLUSION Trigeminal OTR may thus be a novel target for the development of MRM therapeutics.

Abstract
Due to the healthcare burden associated with migraines, prompt and effective treatment is vital to improve patient outcomes and ED workflow. This was a prospective, randomized, double-blind trial. Adults who presented to the ED with a diagnosis of migraine from August of 2019 to March of 2020 were included. Pregnant patients, or with renal impairment were excluded. Patients were randomized to receive intravenous magnesium, prochlorperazine, or metoclopramide. The primary outcome was change in pain from baseline on a numeric rating scale (NRS) evaluated at 30 min after initiation of infusion of study drug. Secondary outcomes included NRS at 60 and 120 min, ED length of stay, necessity for rescue analgesia, and adverse effects. A total of 157 patients were analyzed in this study. Sixty-one patients received magnesium, 52 received prochlorperazine, and 44 received metoclopramide. Most patients were white females, and the median age was 36 years. Hypertension and migraines were the most common comorbidities, with a third of the patients reporting an aura. There was a median decrease in NRS at 30 min of three points across all three treatment arms. The median decrease in NRS (IQR) at 60 min was -4 (2-6) in the magnesium group, -3 (2-5) in the metoclopramide group, and -4.5 (2-7) in the prochlorperazine group (p = 0.27). There were no statistically significant differences in ED length of stay, rescue analgesia, or adverse effects. Reported adverse effects were dizziness, anxiety, and akathisia. No significant difference was observed in NRS at 30 min between magnesium, metoclopramide and prochlorperazine.
