[Standard headache and neuralgia treatments and SARS-CoV-2: opinion of the Spanish Society of Neurology's Headache Study Group]. / Tratamientos habituales utilizados en cefaleas, neuralgias y SARS-CoV-2. Posicionamiento del grupo de estudio de cefaleas de la Sociedad Española de Neurología.

Introduction: In recent months, doubts have arisen among patients, general practitioners, and neurologists as to whether some drugs commonly used in patients with headaches and neuralgia may favour or complicate the disease caused by SARS-CoV-2. Material and methods: We collected information on the opinions of scientific societies and medicines agencies (American, European, and Spanish) to clarify doubts regarding the use of drugs such as lisinopril, candesartan, ibuprofen, corticosteroids, carbamazepine, and monoclonal antibodies targeting the calcitonin gene-related peptide in the context of the COVID-19 pandemic. Results: We make recommendations about the use of standard headache treatments in the context of the COVID-19 pandemic, based on the current scientific evidence. Conclusions: At present, there is no robust scientific argument to formally contraindicate any of the standard treatments employed for headaches and neuralgias.

OnabotulinumtoxinA in chronic migraine: predictors of response. A prospective multicentre descriptive study.

BACKGROUND AND PURPOSE: OnabotulinumtoxinA is a treatment specifically approved for the prophylaxis of chronic migraine in adults. The aim of this study was to assess the effectiveness of OnabotulinumtoxinA in chronic migraine after 1 year of treatment in a real-life setting and to identify clinical predictors of outcome. METHODS: We designed a prospective multicentre study performed in 13 hospitals in Spain. Patients underwent a complete medical history and examination. They were treated with OnabotulinumtoxinA every 12 weeks for 1 year. Data about outcome, adverse events, abortive medication use, emergency room use and disability were collected at 3 and 12 months. RESULTS: A total of 725 subjects completed the study. At 12 months, 79.3% showed >50% reduction in number of headaches per month and 94.9% reported no adverse events. Unilaterality of pain, fewer days of disability per month and milder headache at baseline were correlated with good outcome. Duration of disease <12 months increased the chances of response to treatment with OnabotulinumtoxinA (odds ratio, 1.470; 95% confidence interval, 1.123-2.174; P = 0.045). CONCLUSIONS: This study confirmed the effectiveness of treatment with OnabotulinumtoxinA after 1 year of treatment. The chances of a good outcome may be increased by starting treatment in the first 12 months after chronic migraine diagnosis.

Diagnosis and treatment of disorders of intracranial pressure: consensus statement of the Spanish Society of Neurology's Headache Study Group.

Primary intracranial pressure disorders include idiopathic intracranial hypertension and spontaneous intracranial hypotension. Remarkable advances have been made in the diagnosis and treatment of these 2entities in recent years. Therefore, the Spanish Society of Neurology's Headache Study Group (GECSEN) deemed it necessary to prepare this consensus statement, including diagnostic and therapeutic algorithms to facilitate and improve the management of these disorders in clinical practice. This document was created by a committee of experts belonging to GECSEN, and is based on a systematic review of the literature, incorporating the experience of the participants, and establishes practical recommendations with levels of evidence and grades of recommendation.

Orthodontic treatment timing in growing patients.

AIM: The aim of the study is to estimate the orthodontic treatment timing for the main occlusal problems in growing patients. STUDY DESIGN: a cross-sectional study was carried out in Italian primary and secondary schools from 2008 to 2011; 1375 males and 1642 females, aged between 8 and 13 years, were visited. The sample is divided into two main groups: primary school and secondary school. Selected malocclusion signs were registered according to an occlusal index (ROMA index) by trained and calibrated operators. Prevalence of increased overjet, Class III malocclusion, crossbite, deep bite and open bite observed in each group are compared. A significant decrease of prevalence with age is considered a sign of spontaneous improvement of the malocclusion. RESULTS: Descriptive analyses were performed using frequencies, percentages and chi-square tests to evaluate differences for categorical variables. The level of significance was set at p ≤0.05. Data were analysed with the software SPSS 19.0 for Windows. Class III malocclusion, moderate or severe crossbite and severe increased overjet and overbite seem not to improve spontaneously. CONCLUSION: Early treatment of orthodontic problems that do not improve with age may be helpful to avoid worsening of the condition in permanent dentition. Moderate Class II malocclusion and crossbite treatment can be postponed.

Diagnosis and treatment of trigeminal neuralgia: Consensus statement from the Spanish Society of Neurology's Headache Study Group.

INTRODUCTION: Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder affecting one or more branches of the trigeminal nerve. Despite its relatively low global prevalence, TN is an important healthcare problem both in neurology departments and in emergency departments due to the difficulty of diagnosing and treating the condition and its significant impact on patients' quality of life. For all these reasons, the Spanish Society of Neurology's Headache Study Group has developed a consensus statement on the management of TN. DEVELOPMENT: This document was drafted by a panel of neurologists specialising in headache, who used the terminology of the International Headache Society. We analysed the published scientific evidence on the diagnosis and treatment of TN and establish practical recommendations with levels of evidence. CONCLUSIONS: The diagnosis of TN is based on clinical criteria. Pain attributed to a lesion or disease of the trigeminal nerve is divided into TN and painful trigeminal neuropathy, according to the International Classification of Headache Disorders, third edition. TN is further subclassified into classical, secondary, or idiopathic, according to aetiology. Brain MRI is recommended in patients with clinical diagnosis of TN, in order to rule out secondary causes. In MRI studies to detect neurovascular compression, FIESTA, DRIVE, or CISS sequences are recommended. Pharmacological treatment is the initial choice in all patients. In selected cases with drug-resistant pain or poor tolerance, surgery should be considered.

Telemedicine in the management of patients with headache: current situation and recommendations of the Spanish Society of Neurology's Headache Study Group.

INTRODUCTION: The COVID-19 pandemic has caused an unexpected boost to telemedicine. We analyse the impact of the pandemic on telemedicine applied in Spanish headache consultations, review the literature, and issue recommendations for the implementation of telemedicine in consultations. METHOD: The study comprised 3 phases: 1) review of the MEDLINE database since 1958 (first reported experience with telemedicine); 2) Google Forms survey sent to all members of the Spanish Society of Neurology's Headache Study Group (GECSEN); and 3) online consensus of GECSEN experts to issue recommendations for the implementation of telemedicine in Spain. RESULTS: COVID-19 has increased waiting times for face-to-face consultations, increasing the use of all telemedicine modalities: landline telephone (from 75% before April 2020 to 97% after), mobile telephone (from 9% to 27%), e-mail (from 30% to 36%), and video consultation (from 3% to 21%). Neurologists are aware of the need to expand the availability of video consultations, which are clearly growing, and other e-health and m-health tools. CONCLUSIONS: The GECSEN recommends and encourages all neurologists who assist patients with headaches to implement telemedicine resources, with the optimal objective of offering video consultation to patients under 60-65 years of age and telephone calls to older patients, although each case must be considered on an individual basis. Prior approval and advice must be sought from legal and IT services and the centre's management. Most patients with stable headache and/or neuralgia are eligible for telemedicine follow-up, after a first consultation that must always be held in person.

Calcitonin gene-related peptide in migraine: from pathophysiology to treatment.

INTRODUCTION: It has been observed in recent years that levels of such molecules as calcitonin gene-related peptide (CGRP) and, to a lesser extent, the pituitary adenylate cyclase-activating peptide are elevated during migraine attacks and in chronic migraine, both in the cerebrospinal fluid and in the serum. Pharmacological reduction of these proteins is clinically significant, with an improvement in patients' migraines. It therefore seems logical that one of the main lines of migraine research should be based on the role of CGRP in the pathophysiology of this entity. DEVELOPMENT: The Spanish Society of Neurology's Headache Study Group decided to draft this document in order to address the evidence on such important issues as the role of CGRP in the pathophysiology of migraine and the mechanism of action of monoclonal antibodies and gepants; and to critically analyse the results of different studies and the profile of patients eligible for treatment with monoclonal antibodies, and the impact in terms of pharmacoeconomics. CONCLUSIONS: The clinical development of gepants, which are CGRP antagonists, for the acute treatment of migraine attacks, and CGRP ligand and receptor monoclonal antibodies offer promising results for these patients.

Neuromodulation in headache and craniofacial neuralgia: guidelines from the Spanish Society of Neurology and the Spanish Society of Neurosurgery. / Neuromodulación en cefaleas y neuralgias craneofaciales: Guía de la Sociedad Española de Neurología y de la Sociedad Española de Neurocirugía.

INTRODUCTION: Numerous invasive and non-invasive neuromodulation devices have been developed and applied to patients with headache and neuralgia in recent years. However, no updated review addresses their safety and efficacy, and no healthcare institution has issued specific recommendations on their use for these 2 conditions. METHODS: Neurologists from the Spanish Society of Neurology's (SEN) Headache Study Group and neurosurgeons specialising in functional neurosurgery, selected by the Spanish Society of Neurosurgery (SENEC), performed a comprehensive review of articles on the MEDLINE database addressing the use of the technique in patients with headache and neuralgia. RESULTS: We present an updated review and establish the first set of consensus recommendations of the SEN and SENC on the use of neuromodulation to treat headache and neuralgia, analysing the current levels of evidence on its effectiveness for each specific condition. CONCLUSIONS: Current evidence supports the indication of neuromodulation techniques for patients with refractory headache and neuralgia (especially migraine, cluster headache, and trigeminal neuralgia) selected by neurologists and headache specialists, after pharmacological treatment options are exhausted. Furthermore, we recommend that invasive neuromodulation be debated by multidisciplinary committees, and that the procedure be performed by teams of neurosurgeons specialising in functional neurosurgery, with acceptable rates of morbidity and mortality.

Document of revision and updating of medication overuse headache (MOH). / Documento de revisión y actualización de la cefalea por uso excesivo de medicación (CUEM).

INTRODUCTION: Medication overuse headache is a secondary headache in which the regular or frequent use of analgesics can increase the frequency of the episodes, causing the transition from episodic to chronic headache. The prevalence of medication overuse headache is approximately 1-2%, with higher rates among women aged 30-50 years and with comorbid psychiatric disorders such as depression or anxiety, or other chronic pain disorders. It is important to be familiar with the management of this disease. To this end, the Spanish Society of Neurology's Headache Study Group has prepared a consensus document addressing this disorder. DEVELOPMENT: These guidelines were prepared by a group of neurologists specialising in headache after a systematic literature review and provides consensus recommendations on the proper management and treatment of medication overuse headache. The treatment of medication overuse headache is often complex, and is based on 4 fundamental pillars: education and information about the condition, preventive treatment, discontinuation of the drug being overused, and treatment for withdrawal symptoms. Follow-up of patients at risk of recurrence is important. CONCLUSIONS: We hope that this document will be useful in daily clinical practice and that it will update and improve understanding of medication overuse headache management.

Glutamatergic and morphological alterations associated with early life seizure-induced preconditioning in young rats.

Postnatal day (P)20 rats are sensitive to CA1 injury following a single injection of kainic acid (KA) but are resistant to this injury when animals have a history of two neonatal seizures. We hypothesized that the two earlier seizures led to neuroprotection by a preconditioning mechanism. Therefore, morphology, [Ca(2+)](i) and NMDA subunit proteins of the hippocampus were examined after KA was administered once (1 × KA, on P6, P9, P13 or P20), twice (2 × KA, on P6 and P9) or three times (3 × KA, on P6, P9, P13 or P20). After 1 × KA on P20, the Golgi method revealed marked decreases in spine densities and aborization of CA1 and CA3 apical dendrites. After 3 × KA, morphological alterations were attenuated in CA1 neurons and were similar to pruning observed after 1 × KA on P6 or 2 × KA. After 1 × KA at P13, baseline [Ca(2+)](i) was elevated within pyramidal and dentate granule cells. N-methyl-D-aspartate (NMDA) responses were simultaneously enhanced. After 3 × KA, Ca(2+) elevations were attenuated. Immunohistochemistry revealed selective depletion of the NR2A/B subunit modulator in the same areas. NR1 subunit expression was downregulated in the subiculum and increased in the CA3, causing a significant shift in the NR1:NR2A/B ratio throughout the hippocampus. After 1 × KA or 3 × KA at P20, reduced expression was only observed in areas of cell injury. Results indicate that different changes in morphology and excitatory responses occur depending upon when seizures begin. Partial pruning and persistent shift in the NR1:NR2A/B ratio among excitatory synapses of the hippocampus early in life may produce epileptic tolerance and protect against subsequent insults.

Impact of the COVID-19 pandemic on headache management in Spain: an analysis of the current situation and future perspectives. / Impacto de la pandemia COVID-19 en la atención al paciente con cefalea en España: análisis de situación con una mirada al futuro.

INTRODUCTION: The COVID-19 pandemic has had a great impact on healthcare systems. Spain, where headache is the main reason for outpatient neurology consultation, is one of the countries with the most reported cases of the disease. OBJECTIVE: This study aimed to analyse the impact of the COVID-19 pandemic on headache units in Spain and to evaluate how neurologists see the future of these units. METHODS: We conducted a cross-sectional online survey of headache units during the sixth week of the state of alarm declared in Spain in response to the pandemic. RESULTS: The response rate was 74%, with the participation of centres with different characteristics and from all Autonomous Communities of Spain. Limitations in face-to-face activity were reported by 95.8% of centres, with preferential face-to-face consultation being maintained in 60.4%, and urgent procedures in 45.8%. In 91.7% of centres, the cancelled face-to-face activity was replaced by telephone consultation. 95.8% of respondents stated that they would use personal protection equipment in the future, and 86% intended to increase the use of telemedicine. The majority foresaw an increase in waiting lists (93.8% for initial consultations, 89.6% for follow-up, and 89.4% for procedures) and a worse clinical situation for patients, but only 15% believed that their healthcare structures would be negatively affected in the future. CONCLUSIONS: As a consequence of the pandemic, headache care and research activity has reduced considerably. This demonstrates the need for an increase in the availability of telemedicine in our centres in the near future.

CGRP en migraña: de la fisiopatología a la terapéutica / Calcitonin gene–related peptide in migraine: from pathophysiology to treatment

Introducción: En los últimos años se ha observado que moléculas como el péptido relacionado con el gen de la calcitonina (CGRP) y, en menor grado, el péptido activador de la adenilato-ciclasa pituitaria estaban elevadas durante los ataques de migraña y en la migraña crónica tanto en líquido cefalorraquídeo como en suero y que su reducción farmacológica tenía una significación clínica con una mejoría en la migraña de los pacientes. Es lógico por tanto que una de las principales líneas de investigación en migraña se base en el papel del CGRP en la fisiopatología de esta entidad. Desarrollo: Desde el Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología nos planteamos la redacción de este documento, cuyo objetivo es abordar, basándonos en la evidencia publicada, cuestiones tan importantes como el papel del CGRP en la fisiopatología de la migraña, el mecanismo de acción de los anticuerpos monoclonales y de los gepantes, el análisis crítico de los resultados de los diferentes estudios, el perfil del paciente que podría ser candidato al tratamiento con anticuerpos monoclonales y su impacto en términos de farmacoeconomía. Conclusiones: El desarrollo clínico de los gepantes, antagonistas del CGRP, para el tratamiento agudo del ataque de migraña y de los anticuerpos monoclonales contra ligando y contra el receptor del CGRP ofrecen resultados esperanzadores para nuestros pacientes.

Control and eradication of tuberculosis in cattle: a systematic review of economic evidence.

Bovine tuberculosis (TB) is a disease of zoonotic importance for which control and eradication programmes have been carried out in many countries for decades. While the impact of these programmes on public health is still uncertain, the impact on trade is significant because of movement restrictions for animals, costs of testing and culling. The objective of this systematic review was to provide a contribution to the general debate over costs against benefits for the control and eradication of bovine TB in cattle. The search strategy was performed on four electronic databases following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The selection process, data abstraction and quality appraisal were carried out according to the Cochrane Collaboration guidelines. The search identified 66 articles out of which eight fulfilled the inclusion criteria. The evidence gathered in this review by combining the conclusions of the most methodologically sound articles supports the idea that, when multiple cost and benefit components are taken into account, efforts to control or eradicate bovine TB may be effective in reducing disease prevalence, economically viable and worth doing.

INTRODUCCIÓN: En los últimos meses han surgido dudas por parte de pacientes, médicos de familia y neurólogos sobre la posibilidad de que algunos de los fármacos que habitualmente se utilizan en cefaleas y neuralgias puedan facilitar o complicar la infección por el SARS-CoV-2. MATERIAL Y MÉTODOS: Hemos recabado información sobre el posicionamiento de sociedades científicas, así como de las distintas Agencias de Medicamentos (americana, europea y española) para poder esclarecer dudas respecto al uso de fármacos como lisinopril, candesartán, ibuprofeno, corticoides, carbamazepina, anticuerpos monoclonales contra el péptido relacionado con el gen de la calcitonina (CGRP) durante la pandemia por COVID-19. RESULTADOS: Planteamos recomendaciones acerca del uso de fármacos habituales en el tratamiento de las cefaleas en el contexto de la pandemia por COVID-19, basándonos en las evidencias de las que disponemos en el momento actual. CONCLUSIONES: Actualmente no existe ningún argumento científico robusto para contraindicar formalmente ninguno de los tratamientos que se emplean en cefaleas y neuralgias

INTRODUCTION: In recent months, doubts have arisen among patients, general practitioners, and neurologists as to whether some drugs commonly used in patients with headaches and neuralgia may favour or complicate the disease caused by SARS-CoV-2. MATERIAL AND METHODS: We collected information on the opinions of scientific societies and medicines agencies (American, European, and Spanish) to clarify doubts regarding the use of drugs such as lisinopril, candesartan, ibuprofen, corticosteroids, carbamazepine, and monoclonal antibodies targeting the calcitonin generelated peptide in the context of the COVID-19 pandemic. RESULTS: We make recommendations about the use of standard headache treatments in the context of the COVID-19 pandemic, based on the current scientific evidence. CONCLUSIONS: At present, there is no robust scientific argument to formally contraindicate any of the standard treatments employed for headaches and neuralgias
