RESUMEN

BACKGROUND: Argentina has one of the largest territories in the world, which spreads over a lengthy latitudinal span. Its population is mainly composed of a mixture of South American natives and the descendants of numerous waves of European immigrants. Results from a previous study suggested that the prevalence of migraine in Argentina is the lowest in the region. Here we aimed to reassess the prevalence of migraine in Argentina applying a more sensitive and specific screening tool. METHODS: We conducted a random computer assisted telephonic interview (n= 2500) using the Migraine Screen Questionnaire to evaluate the prevalence of migraine and some of its features among Argentinian adults. RESULTS: The overall prevalence of migraine was 9.5% (14% in females and 5% in males). Estimated migraine prevalence rates ranged between 6.3% and 12% across different regions. The approximated prevalence of high frequency and chronic migraine were 1.9% and 1.5% of the total population respectively. Consumption of analgesics on 10 or more days per month was reported by 18% of migraine sufferers (≈1.7% of the population). CONCLUSIONS: The prevalence of migraine in Argentina is higher than previously reported. Prevalence rates vary extensively across the territory. Specifically evaluating the determinants of these variations might be a promising avenue of research.

RESUMEN

OBJECTIVE: The aim of this retrospective cohort study was to analyze responses to intravenous (IV) phenytoin (PHT) for trigeminal neuralgia (TN) crisis in a group of patients treated at our institution. BACKGROUND: TN is one of the most common causes of facial pain. Its treatment relies on preventive therapy with either carbamazepine or oxcarbazepine. During severe pain episodes, patients may be unable to eat, drink, or even swallow oral medication, requiring in-hospital treatment. There is scarce evidence to support IV medication use for TN, making management of this condition difficult. METHODS: We reviewed clinical records of patients with TN crisis consulting the emergency department at a tertiary neurological referral center in Buenos Aires, Argentina, treated with IV PHT as analgesic strategy, and with at least 1-month posttreatment follow-up. Demographic features, magnetic resonance imaging findings, and therapeutic management were analyzed. RESULTS: Thirty-nine patients with TN were included, 18 (46.2%) receiving IV PHT more than once (total number of infusions administered, 65). Immediate pain relief was observed in 89.2% (58/65) and 15.4% (10/65) presented side effects. CONCLUSIONS: We recommend IV PHT as acute rescue treatment in TN crisis.

RESUMEN

OBJECTIVE: The aim of this study was to describe a group of patients with chronic headache disorders (CH) and medication overuse headache (MOH) treated with intravenous chlorpromazine (IVC). We hypothesized that IVC is an effective and safe addition to well-known treatment strategies for CH and MOH management. INTRODUCTION: Up to 4% of the general population could experience CH. Most cases occur in women, in association with MOH. To date, evidence to support different treatment strategies is lacking. Although IVC is frequently used in the emergency room (ER), documentation on its use as supportive treatment for CH and for withdrawal management of MOH is poor. METHODS: A retrospective cohort of patients hospitalized to receive treatment for CH in a specialized neurological center in Argentina was analyzed. RESULTS: A total of 35 CH patients were included. Of the 35 patients, 33 (94%) patients also presented MOH. Patients reported only minor side effects to IVC administration (mainly drowsiness and symptomatic hypotension). Three months after inpatient treatment, the number of ER visits made by these patients decreased from an average of 2.8 in the 3 months prior to hospitalization to 0.7 after it (72%, P = .009). Headache frequency decreased in 20/34 (59%) patients during the same time period. Pain levels had dropped from a mean of 8 points at admission (in the scale of 1-10) to 2 points at discharge. In the first 3 months of follow-up, the average number of days per month in which patients experienced headache decreased from 28.9 to 15.4 days (53.3%, P < .0001). CONCLUSION: In this particular group of inpatients, there were no significant safety issues with IVC administration and the study might suggest that the efficacy of IVC as an add-on treatment for CH and MOH.

RESUMEN

BACKGROUND AND PURPOSE: The relationship between unruptured intracranial aneurysms (UIAs) and chronic headache and the impact of aneurysm treatment on headache outcome are controversial. The aim of this study was to determine clinical features of a supposedly primary headache in patients with UIA. We also assessed changes in headache characteristics after UIA treatment. METHODS: We examined clinical and imaging data of patients in whom a UIA was diagnosed during diagnostic workup of a suspected primary headache. Medical records were reviewed and personal telephone follow-ups were performed after UIA treatment to assess changes in the frequency and intensity of the headache. RESULTS: Forty-two patients (76%) reported a substantial improvement in headache frequency and intensity after UIA treatment. Forty-five patients (81%) reported a decrease in headache frequency from a median of 8 days/month before treatment to 1 day/month after treatment (95% confidence interval [CI] 81-83, P < .001). The average intensity in an analog pain scale was 7.7 ± 1.6 before treatment and 5.6 ± 2.4 after treatment (P < .001). Higher headache frequency was associated with a greater odd of improvement after treatment (odds ratio 1.12, 95% CI 1.0-1.26, P = .03). No associations were found between the type of headache, type of treatment (endovascular versus surgical), number, size, or localization of the aneurysms and the response to treatment. CONCLUSIONS: The treatment of UIA had a robust beneficial effect on previous headache. Although a "placebo" effect of aneurysm treatment cannot be ruled out, these results suggest a potential association between UIA and certain chronic headaches usually considered to be primary.

RESUMEN

AIMS: To describe headache characteristics among celiac disease (CD) patients and to analyze the relationship between CD and headache. METHODS: An online survey analyzing the characteristics of headache and its response to the gluten-free diet (GFD) in celiac patients was published on Argentinean Celiac social networks, open to the public to complete. The results were analyzed using chi-square test or Mann-Whitney test accordingly. RESULTS: A total of 1,517 subjects completed the survey, and 866 (55.2%) met the inclusion criteria (headache and CD confirmed with positive biopsy). The subjects were predominantly female (94.5%) and had a median age of 39 ± 11.27 years. Tension-type headache was the most prevalent headache type (52%), followed by migraine without (32.5%) and with aura (15.4%), respectively. Of the included participants, 24% reported headache as the main symptom that resulted in the diagnosis of CD. Following initiation of GFD, headache frequency and intensity improved significantly more in participants with migraine than tension-type headache (P = .02 and P = .013, respectively). Compliance to GFD was higher among subjects with severe manifestations (77% vs 66%, P = .05), and compliant individuals showed a 48% improvement in headache frequency (P = .049). An association between food transgressions and headache was better recognized by migraineurs (P = .02). CONCLUSION: These results suggest that strict compliance to the GFD could improve headache in celiac patients with headache, even in those without gastrointestinal symptoms. This observation could provide an additional factor when convincing patients to follow a GFD, thus reducing the morbidity related to CD.

RESUMEN

INTRODUCCIÓN: La migraña es un trastorno muy prevalente que se estima que afecta a alrededor del 15% de los sujetos adultos. Durante los últimos años, se ha evaluado la eficacia y la seguridad de los anticuerpos monoclonales que actúan sobre la vía del péptido relacionado con el gen de la calcitonina (AM-PRGC) en la migraña. Diversos grupos de trabajo internacionales han intentado clarificar y normatizar el uso de estos medicamentos en la migraña. Sin embargo, en muchas ocasiones se extrapolan datos de otras regiones que no contemplan la realidad de cada lugar o son difíciles de implementar. OBJETIVO: Proveer recomendaciones sobre el uso de AM-PRGC en pacientes con migraña en Argentina. DESARROLLO: Un grupo de expertos de Argentina conformado por neurólogos, mediante metodología de ronda de encuestas en la distancia y reuniones presenciales, llevó adelante la elaboración del consenso pretendido para el uso de AM-PRGC en pacientes con migraña en Argentina. Se establecieron las recomendaciones basadas en la evidencia publicada y en el criterio de los expertos que participaron. Las recomendaciones se enfocaron en el momento de usar los AM-PRGC en la migraña tanto crónica como episódica, la duración, los cuidados y el entorno para hacerlo. CONCLUSIÓN: Las recomendaciones establecidas en el presente consenso permitirán optimizar el manejo de los AM-PRGC en pacientes con migraña en Argentina


INTRODUCTION: Migraine is a very prevalent disorder that is estimated to affect about 15% of adult subjects. Recently, the efficacy and safety of monoclonal antibodies that act on the calcitonin gene-related peptide pathway (MA-CGRP) has been evaluated in migraine. Several groups around the world have developed consensus guidelines about the use of monoclonal antibodies, however, in some regions is difficult to extrapolate the recommendations. AIM: To provide recommendations for the use of MA-CGRP in migraine in Argentina. DEVELOPMENT: A group of neurology experts from Argentina, by using the online surveys methodology as well as face to face meetings developed the intended consensus for the use of MA-CGRP in migraine in Argentina. Recommendations were established based on published evidence and the expert opinion. Recommendations focused on how, when, treatment duration and patients follow up. CONCLUSION: The recommendations of this consensus guidelines attempt to optimize the use of MA-CGRP in migraine in Argentina
