RESUMEN

BACKGROUND: Headache is the most frequent symptom of cerebral venous thrombosis (CVT) but there is limited information about the frequency and phenotype of headache, weeks to months after cerebral venous thrombosis (post-cerebral venous thrombosis headache, PCH). OBJECTIVE: To assess the frequency, characteristics and predictors of PCH. METHODS: In this cross-sectional study, the frequency and characteristics of PCH were assessed in cerebral venous thrombosis survivors. Patients were interviewed between six months and five years after the cerebral venous thrombosis diagnosis. Clinical and imaging characteristics at the time of cerebral venous thrombosis diagnosis, as well as history of headache prior to cerebral venous thrombosis were compared in subjects with (GroupPCH) and without PCH (Groupcontrol). RESULTS: Subjects (n = 100; 82% women) were assessed, on average, at 1.1 ± 1.6 years of follow-up. PCH was present in 59% of the patients, phenotypes of tension-type-like headache were present in 31/59 (52.6%) and of migraine-like headache in 16/59 (27.1%). History of primary headache prior to cerebral venous thrombosis was significantly more common (OR: 6.4; 95% CI: 1.7-36.3) in GroupPCH (33.9%) than in Groupcontrol (7.3%). CONCLUSION: PCH was present in more than half of the patients. History of prior headache may be a risk factor for PCH. Prospective studies are required to confirm these findings and determine mechanisms, as well as interventions for prevention and treatment of PCH.

RESUMEN

OBJECTIVE: To describe the clinical, neurological, neuroimaging, and cerebrospinal fluid (CSF) findings associated with encephalopathy in patients admitted to a COVID-19 tertiary reference center. METHODS: We retrospectively reviewed records of consecutive patients with COVID-19 evaluated by a consulting neurology team from March 30, 2020 through May 15, 2020. RESULTS: Fifty-five patients with confirmed SARS-CoV-2 were included, 43 of whom showed encephalopathy, and were further divided into mild, moderate, and severe encephalopathy groups. Nineteen patients (44%) had undergone mechanical ventilation and received intravenous sedatives. Eleven (26%) patients were on dialysis. Laboratory markers of COVID-19 severity were very common in encephalopathy patients, but did not correlate with the severity of encephalopathy. Thirty-nine patients underwent neuroimaging studies, which showed mostly non-specific changes. One patient showed lesions possibly related to CNS demyelination. Four had suffered an acute stroke. SARS-CoV-2 was detected by RT-PCR in only one of 21 CSF samples. Two CSF samples showed elevated white blood cell count and all were negative for oligoclonal bands. In our case series, the severity of encephalopathy correlated with higher probability of death during hospitalization (OR = 5.5 for each increment in the degree of encephalopathy, from absent (0) to mild (1), moderate (2), or severe (3), p < 0.001). CONCLUSION: In our consecutive series with 43 encephalopathy cases, neuroimaging and CSF analysis did not support the role of direct viral CNS invasion or CNS inflammation as the cause of encephalopathy.

RESUMEN

BACKGROUND: Rapidly progressive dementia (RPD) is usually associated with Creutzfeldt-Jakob disease, a fatal condition. Current advances in the understanding of immune-mediated diseases allow the diagnosis of previously unrecognized treatable RPDs. OBJECTIVE OF THE STUDY: The objective of the study was to describe the prevalence and causes of RPD in a neurology service, identifying potentially reversible causes. METHODS: We carried out a cross-sectional evaluation of all patients admitted to the neurology unit of a tertiary hospital in Brazil between March 2012 and February 2015. We included patients who had progressed to moderate or severe dementia within a few months or up to 2 years at the time of hospitalization, and used multivariable logistic regression analysis to identify factors associated with a favorable outcome. RESULTS: We identified 61 RPD (3.7%) cases among 1648 inpatients. Mean RPD patients' age was 48 years, and median time to progression was 6.4 months. Immune-mediated diseases represented the most commonly observed disease group in this series (45.9% of cases). Creutzfeldt-Jakob disease (11.5%) and nonprion neurodegenerative diseases (8.2%) were less common in this series. Outcome was favorable in 36/61 (59.0%) RPD cases and in 28/31 (89.3%) of immune-mediated cases. Favorable outcome was associated with shorter time from symptom onset to diagnosis and abnormal cerebrospinal fluid findings. CONCLUSIONS: Immune-mediated diseases were the most common cause of RPD in this series. Timely evaluation and diagnosis along with institution of appropriate therapy are required in RPD, especially in view of potentially reversible causes.

RESUMEN

A 46-year-old man presented with severe visual loss and optic atrophy associated with optociliary shunt vessels. The diagnostic work-up revealed intracranial hypertension and cerebral venous sinus stenosis, with no evidence of previous thrombosis. In view of the severe visual dysfunction, both eyes were submitted to optic nerve sheath fenestration. After surgery, a regression of collateral vessels was observed in both eyes.

RESUMEN

Therapeutic plasma exchange (TPE) can improve disability recovery after neuromyelitis optica spectrum disease (NMOSD) attacks, but its effectiveness and safety in Latin-American patients with access barriers and diverse ethnicity is underexplored. We carried out a retrospective cohort study with NMOSD patients that underwent TPE. 84 NMOSD attacks in 68 patients were evaluated. Despite a median 25-day delay from symptom onset to TPE, 65,5% of patients showed significant improvement. Adverse events occurred in 39% of patients, usually transitory and with no fatalities.

RESUMEN

Optic neuritis (ON) admits diverse differential diagnoses. Petzold proposed diagnostic criteria for ON in 2022, although real-world application of these criteria is missing. We conducted a retrospective review of patients with ON. We classified patients into definite or possible ON, and into groups A (typical neuritis), B (painless), or C (binocular) and estimated the frequency of etiologies for each group. We included 77 patients, with 62% definite and 38% possible ON. CRION and NMOSD-AQP4 negative-ON were less commonly seen in definite ON. Application of the 2022 criteria revealed a lower-than-expected frequency of definite ON, particularly for seronegative non-MS causes.

RESUMEN

BACKGROUND: Optic neuritis (ON), a major cause of visual impairment in young adults, is generally associated with rapid visual recovery when treated with intravenous methylprednisolone treatment (IVMPT). However, the optimal duration of such treatment is unknown, ranging from three to seven days in clinical practice. We aimed to compare the visual recovery in patients treated with 5-day or 7-day duration IVMPT. METHODS: We performed a retrospective cohort study of consecutive patients with ON in São Paulo, Brazil, from 2016 to 2021. We compared the proportion of participants with visual impairment in 5-day and 7-day treatment schedules at discharge, at 1 month and between 6 and 12 months after the diagnosis of ON. The findings were adjusted to age, severity of the visual impairment, co-intervention with plasma exchange, time from symptom onset to IVMPT and the etiology of the ON to mitigate indication bias. RESULTS: We included 73 patients with ON treated with 5 or 7-day duration of 1 g/d intravenous methylprednisolone therapy. Visual impairment at 6-12 months in the 5-day or the 7-day treatment groups was similar (57% x 59%, p > 0.9, Odds Ratio 1.03 [95% CI 0.59-1.84]). The results were similar after adjusting for prognostic variables and when observed at different time points. CONCLUSION: Visual recovery is similar in patients treated with 5-day and 7-day duration treatments of 1 g/day intravenous methylprednisolone, suggesting a ceiling effect. Limiting the duration of the treatment can reduce hospital stay and costs, without interfering with clinical benefit.

RESUMEN

Obesity and headache disorders are two very common conditions in the general population that have been increasing in incidence over the last decades. Recent studies have shown a significant relationship between obesity and headaches, particularly migraine, with an important role in whether the disease is chronic. On the other hand, no such association was found with tension-type headaches. Studies showing an overlapping of hunger-control pathways and those involved in the pathophysiology of migraine may justify the close association between obesity and migraine. Moreover, a secondary headache for which obesity is a strong risk factor is idiopathic Intracranial Hypertension (pseudotumor cerebri), with several studies showing the impact of weight reduction/bariatric surgery in the treatment of the disease. In conclusion, since obesity is a modifiable risk factor, it is important for physicians treating patients with headaches, and particularly migraine, to be aware of the association between these two disorders.

RESUMEN

BACKGROUND: Idiopathic Intracranial Hypertension (IIH) is a secondary headache with a steadily growing incidence. Currently, there is little evidence to guide the treatment of IIH. OBJECTIVE: To review the pathophysiology of IIH, with focus on the role of obesity as a risk factor, and the implications for new therapeutic perspectives. METHODS: in this narrative review, we summarized the current knowledge on treatment options highlighting available evidence for managing intracranial hypertension, obesity, and headache. RESULTS: Clinical Presentation: headache is the most common symptom and a significant cause of quality-of-life impairment. Visual loss is common in the diagnosis. Pathophysiology: there is no unified theory able to explain all symptoms and the evolution of the disease. There is growing data pointing to metabolic changes and obesity with a central role in IIH pathophysiology. Treatment: most published data on IIH treatment is related to pressure control and protection from visual loss. Acetazolamide and cerebrospinal fluid diversion are the best options available. Optic nerve sheath fenestration might be useful to temporally control the pressure over the optic nerve and thus protect from visual deterioration. Recently, venous sinus stenting has proven to be a safe option in selected cases. Finally, bariatric surgery has proven to effectively control elevated intracranial pressure. CONCLUSION: IIH is a potential cause of high disability. Early recognition is important, and treatment should be tailored to the needs of each case. There is a lack of research on headache management, which might persist after ICP control.

RESUMEN

The Brazilian Headache Society (Sociedade Brasileira de Cefaleia, SBCe, in Portuguese) nominated a Committee of Authors with the aim of establishing a consensus with recommendations regarding prophylactic treatment for episodic migraine based on articles published in the worldwide literature, as well as personal experience. Migraine affects 1 billion people around the world and more than 30 million Brazilians. In addition, it is an underdiagnosed and undertreated disorder. It is well known within the medical community of neurologists, and especially among headache specialists, that there is a need to disseminate knowledge about prophylactic treatment for migraine. For this purpose, together with the need for drug updates and to expand knowledge of the disease itself (frequency, intensity, duration, impact and perhaps the progression of migraine), this Consensus was developed, following a full online methodology, by 12 groups who reviewed and wrote about the pharmacological categories of the drugs used and, at the end of the process, met to read and establish conclusions for this document. The drug classes studied were: anticonvulsants, tricyclic antidepressants, monoclonal anti-calcitonin gene-related peptide (anti-CGRP) antibodies, beta-blockers, antihypertensives, calcium channel inhibitors, other antidepressants (selective serotonin reuptake inhibitors, SSRIs, and dual-action antidepressants), other drugs, and polytherapy. Hormonal treatment and anti-inflammatories and triptans in minimum prophylaxis schemes (miniprophylaxis) will be covered in a specific chapter. The drug classes studied for part I of the Consensus were: anticonvulsants, tricyclic antidepressants, monoclonal anti-CGRP antibodies, and beta-blockers.


A Sociedade Brasileira de Cefaleia (SBCe) nomeou um Comitê de Autores com o objetivo de estabelecer um consenso com recomendações sobre o tratamento profilático da enxaqueca episódica com base em artigos da literatura mundial e da experiência pessoal. A enxaqueca é um distúrbio subdiagnosticado e subtratado que acomete um bilhão de pessoas no mundo e mais de 30 milhões de brasileiros. É conhecido na comunidade médica de neurologistas e, sobretudo, dos especialistas em cefaleia, a necessidade de se divulgar o conhecimento sobre o tratamento profilático da enxaqueca. Com esta finalidade, aliada às necessidades de atualizações de drogas e de se aumentar o conhecimento sobre a doença em si (frequência, intensidade, duração, impacto e talvez a progressão da enxaqueca), foi elaborado este Consenso, com metodologia totalmente on-line, por 12 grupos que revisaram e escreveram sobre as categorias farmacológicas das drogas e, ao final, reuniram-se para a leitura e conclusão do documento. As classes de drogas estudadas para este Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais do antipeptídeo relacionado ao gene da calcitonina (peptídeo relacionado ao gene da calcitonina ­ anti-CGRP), betabloqueadores, anti-hipertensivos, inibidores dos canais de cálcio, outros antidepressivos (inibidores seletivos de recaptação de serotonina, ISRSs, e antidepressivos de ação dual), outras drogas, e politerapia. O tratamento hormonal, bem como anti-inflamatórios e triptanas em esquema de profilaxia mínima (miniprofilaxia), será abordado em um capítulo próprio. As classes de drogas estudadas na parte I do Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais anti-CGRP, e betabloqueadores.

RESUMEN

BACKGROUND: Migraine affects 1 billion people worldwide and > 30 million Brazilians; besides, it is an underdiagnosed and undertreated disorder. OBJECTIVE: The need to disseminate knowledge about the prophylactic treatment of migraine is known, so the Brazilian Headache Society (SBCe, in the Portuguese acronym) appointed a committee of authors with the objective of establishing a consensus with recommendations on the prophylactic treatment of episodic migraine based on articles from the world literature as well as from personal experience. METHODS: Meetings were held entirely online, with the participation of 12 groups that reviewed and wrote about the pharmacological categories of drugs and, at the end, met to read and finish the document. The drug classes studied in part II of this Consensus were: antihypertensives, selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, calcium channel blockers, other drugs, and rational polytherapy. RESULTS: From this list of drugs, only candesartan has been established as effective in controlling episodic migraine. Flunarizine, venlafaxine, duloxetine, and pizotifen were defined as likely to be effective, while lisinopril, enalapril, escitalopram, fluvoxamine, quetiapine, atorvastatin, simvastatin, cyproheptadine, and melatonin were possibly effective in prophylaxis of the disease. CONCLUSIONS: Despite an effort by the scientific community to find really effective drugs in the treatment of migraine, given the large number of drugs tested for this purpose, we still have few therapeutic options.

RESUMEN

BACKGROUND: Neurological manifestations of COVID-19 are still incompletely understood. Neurological manifestations may be due to direct viral effect on neurons and glial cells, to an immune-mediated response to the virus, or to a hypercoagulable state and associated endothelial damage, as well as to severe systemic disease with prolonged intensive care unit stay. OBJECTIVE: To describe two patients with severe SARS-CoV-2 infection and delayed recovery of consciousness after sedation withdrawal, in whom MRI disclosed multifocal white matter brain lesions, compatible with the diagnosis of acute disseminated encephalomyelitis. METHODS: Observational report of two cases of severe COVID-19 infection in patients from two tertiary hospitals in São Paulo, Brazil. RESULTS: These patients underwent neurologic and systemic evaluation for delayed awakening after sedation withdrawal. MRI displayed multifocal centrum semiovale lesions, suggestive of demyelinating inflammation. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) for SARS-CoV-2 was negative in both cases. CONCLUSION: A recurrent pattern of multifocal white matter lesions can occur in COVID-19 patients, possibly associated with delayed awakening. Additional studies are necessary to elucidate the role of the viral infection and of inflammatory and immune-mediated associated changes in neurological manifestations of COVID-19.

RESUMEN

BACKGROUND: More than one-third of COVID-19 patients present neurological symptoms ranging from anosmia to stroke and encephalopathy. Furthermore, pre-existing neurological conditions may require special treatment and may be associated with worse outcomes. Notwithstanding, the role of neurologists in COVID-19 is probably underrecognized. OBJECTIVE: The aim of this study was to report the reasons for requesting neurological consultations by internists and intensivists in a COVID-19-dedicated hospital. METHODS: This retrospective study was carried out at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Brazil, a 900-bed COVID-19 dedicated center (including 300 intensive care unit beds). COVID-19 diagnosis was confirmed by SARS-CoV-2-RT-PCR in nasal swabs. All inpatient neurology consultations between March 23rd and May 23rd, 2020 were analyzed. Neurologists performed the neurological exam, assessed all available data to diagnose the neurological condition, and requested additional tests deemed necessary. Difficult diagnoses were established in consensus meetings. After diagnosis, neurologists were involved in the treatment. RESULTS: Neurological consultations were requested for 89 out of 1,208 (7.4%) inpatient COVID admissions during that period. Main neurological diagnoses included: encephalopathy (44.4%), stroke (16.7%), previous neurological diseases (9.0%), seizures (9.0%), neuromuscular disorders (5.6%), other acute brain lesions (3.4%), and other mild nonspecific symptoms (11.2%). CONCLUSIONS: Most neurological consultations in a COVID-19-dedicated hospital were requested for severe conditions that could have an impact on the outcome. First-line doctors should be able to recognize neurological symptoms; neurologists are important members of the medical team in COVID-19 hospital care.

RESUMEN

We report the cases of two women who presented a clinical condition compatible with the SUNCT (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing) syndrome. Both presented normal clinical and neurological examination and MRI compatible with microangiopathy. The first one related headache attacks for three years, occurring several times a day when she masticated or yawned. She had a history of multiple failed therapies. The pain was controlled after the use of gabapetin (600 mg per day). The second one related she had daily headaches for six months that occurred from 20 to 40 times per day. At the first visit to the ambulatory, she related she was using carbamazepine (600 mg per day) and chlorpromazine (15 mg per day) having a partial response. Administration of gabapentin (1200 mg per day) led to complete resolution of the pain attacks, but the patient continue to have episodes of conjunctival injection.

RESUMO Obesidade e cefaleias são duas condições muito frequentes na população geral e que vem aumentando em incidência nas últimas décadas. Estudos recentes têm demonstrado uma significativa relação entre obesidade e cefaleia, particularmente na enxaqueca, com papel importante na cronificação da doença. Por outro lado, não se observa tal associação com cefaleia do tipo tensão. Trabalhos que mostram uma sobreposição das vias de controle da fome e daquelas envolvidas na fisiopatologia da enxaqueca podem justificar a íntima associação entre obesidade e enxaqueca. Além disso, uma cefaleia secundária para a qual a obesidade é um forte fator de risco é a Hipertensão Intracraniana Idiopática (pseudotumor cerebral), inclusive com diversos estudos mostrando o impacto da redução do peso/cirurgia bariátrica no tratamento da doença. Concluindo, visto que a obesidade é um fator de risco modificável, é importante para os médicos que tratam de pacientes com cefaleia e, particularmente, enxaqueca, estarem cientes da associação entre essas duas comorbidades.

RESUMEN

ABSTRACT Background: Idiopathic Intracranial Hypertension (IIH) is a secondary headache with a steadily growing incidence. Currently, there is little evidence to guide the treatment of IIH. Objective: To review the pathophysiology of IIH, with focus on the role of obesity as a risk factor, and the implications for new therapeutic perspectives. Methods: in this narrative review, we summarized the current knowledge on treatment options highlighting available evidence for managing intracranial hypertension, obesity, and headache. Results: Clinical Presentation: headache is the most common symptom and a significant cause of quality-of-life impairment. Visual loss is common in the diagnosis. Pathophysiology: there is no unified theory able to explain all symptoms and the evolution of the disease. There is growing data pointing to metabolic changes and obesity with a central role in IIH pathophysiology. Treatment: most published data on IIH treatment is related to pressure control and protection from visual loss. Acetazolamide and cerebrospinal fluid diversion are the best options available. Optic nerve sheath fenestration might be useful to temporally control the pressure over the optic nerve and thus protect from visual deterioration. Recently, venous sinus stenting has proven to be a safe option in selected cases. Finally, bariatric surgery has proven to effectively control elevated intracranial pressure. Conclusion: IIH is a potential cause of high disability. Early recognition is important, and treatment should be tailored to the needs of each case. There is a lack of research on headache management, which might persist after ICP control.


RESUMO Antecedentes: A Hipertensão Intracraniana Idiopática (HII) é uma cefaleia secundária com incidência crescente. Atualmente há pouca evidência disponível na literatura referente ao manejo da HII. Objetivo: O entendimento da fisiopatologia e o papel central da obesidade como fator de risco para HII abriu novas perspectivas de tratamento. Métodos: nessa revisão narrativa, objetivamos revisar as principais opções de tratamento disponíveis atualmente para o manejo da HII, controle da obesidade e da cefaleia. Resultados: Apresentação clínica: a cefaleia é o sintoma mais comum e uma importante causa de impacto na qualidade de vida, e o déficit visual é um achado comum no diagnóstico. Fisiopatologia: atualmente não existe uma teoria unificada capaz de explicar satisfatoriamente os sintomas e a evolução da doença. Um crescente corpo de evidências aponta para o papel central das alterações metabólicas e da obesidade na fisiopatologia da HII. Tratamento: a maioria dos dados publicados sobre HII estão relacionados a medidas para controle da hipertensão intracraniana e proteção da visão. Acetazolamida e Derivação Ventriculo Peritoneal são as principais alternativas com esse fim. A fenestração do nervo óptico pode ser útil como medida termporaria de controle da pressão sobre o nervo óptico e proteção contra a progressão do déficit visual. Cirurgia bariátrica se mostrou efetiva no controle da pressão intracraniana. Conclusão: A HII é uma causa importante de incapacidade cujo reconhecimento precoce é importante. O tratamento deve ser individualizado. Atualmente há uma importante defasagem de evidências sobre o manejo da cefaleia nesse grupo de pacientes.

RESUMEN

Abstract Background Migraine affects 1 billion people worldwide and > 30 million Brazilians; besides, it is an underdiagnosed and undertreated disorder. Objective The need to disseminate knowledge about the prophylactic treatment of migraine is known, so the Brazilian Headache Society (SBCe, in the Portuguese acronym) appointed a committee of authors with the objective of establishing a consensus with recommendations on the prophylactic treatment of episodic migraine based on articles from the world literature as well as from personal experience. Methods Meetings were held entirely online, with the participation of 12 groups that reviewed and wrote about the pharmacological categories of drugs and, at the end, met to read and finish the document. The drug classes studied in part II of this Consensus were: antihypertensives, selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, calcium channel blockers, other drugs, and rational polytherapy. Results From this list of drugs, only candesartan has been established as effective in controlling episodic migraine. Flunarizine, venlafaxine, duloxetine, and pizotifen were defined as likely to be effective, while lisinopril, enalapril, escitalopram, fluvoxamine, quetiapine, atorvastatin, simvastatin, cyproheptadine, and melatonin were possibly effective in prophylaxis of the disease. Conclusions Despite an effort by the scientific community to find really effective drugs in the treatment of migraine, given the large number of drugs tested for this purpose, we still have few therapeutic options.

RESUMEN

Abstract The Brazilian Headache Society (Sociedade Brasileira de Cefaleia, SBCe, in Portuguese) nominated a Committee of Authors with the aim of establishing a consensus with recommendations regarding prophylactic treatment for episodic migraine based on articles published in the worldwide literature, as well as personal experience. Migraine affects 1 billion people around the world and more than 30 million Brazilians. In addition, it is an underdiagnosed and undertreated disorder. It is well known within the medical community of neurologists, and especially among headache specialists, that there is a need to disseminate knowledge about prophylactic treatment for migraine. For this purpose, together with the need for drug updates and to expand knowledge of the disease itself (frequency, intensity, duration, impact and perhaps the progression of migraine), this Consensus was developed, following a full online methodology, by 12 groups who reviewed and wrote about the pharmacological categories of the drugs used and, at the end of the process, met to read and establish conclusions for this document. The drug classes studied were: anticonvulsants, tricyclic antidepressants, monoclonal anti-calcitonin gene-related peptide (anti-CGRP) antibodies, beta-blockers, antihypertensives, calcium channel inhibitors, other antidepressants (selective serotonin reuptake inhibitors, SSRIs, and dual-action antidepressants), other drugs, and polytherapy. Hormonal treatment and anti-inflammatories and triptans in minimum prophylaxis schemes (miniprophylaxis) will be covered in a specific chapter. The drug classes studied for part I of the Consensus were: anticonvulsants, tricyclic antidepressants, monoclonal anti-CGRP antibodies, and beta-blockers.


Resumo A Sociedade Brasileira de Cefaleia (SBCe) nomeou um Comitê de Autores com o objetivo de estabelecer um consenso com recomendações sobre o tratamento profilático da enxaqueca episódica com base em artigos da literatura mundial e da experiência pessoal. A enxaqueca é um distúrbio subdiagnosticado e subtratado que acomete um bilhão de pessoas no mundo e mais de 30 milhões de brasileiros. É conhecido na comunidade médica de neurologistas e, sobretudo, dos especialistas em cefaleia, a necessidade de se divulgar o conhecimento sobre o tratamento profilático da enxaqueca. Com esta finalidade, aliada às necessidades de atualizações de drogas e de se aumentar o conhecimento sobre a doença em si (frequência, intensidade, duração, impacto e talvez a progressão da enxaqueca), foi elaborado este Consenso, com metodologia totalmente on-line, por 12 grupos que revisaram e escreveram sobre as categorias farmacológicas das drogas e, ao final, reuniram-se para a leitura e conclusão do documento. As classes de drogas estudadas para este Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais do antipeptídeo relacionado ao gene da calcitonina (peptídeo relacionado ao gene da calcitonina — anti-CGRP), betabloqueadores, anti-hipertensivos, inibidores dos canais de cálcio, outros antidepressivos (inibidores seletivos de recaptação de serotonina, ISRSs, e antidepressivos de ação dual), outras drogas, e politerapia. O tratamento hormonal, bem como anti-inflamatórios e triptanas em esquema de profilaxia mínima (miniprofilaxia), será abordado em um capítulo próprio. As classes de drogas estudadas na parte I do Consenso foram: anticonvulsivantes, antidepressivos tricíclicos, anticorpos monoclonais anti-CGRP, e betabloqueadores.

RESUMEN

For twelve years, the subject of this report, a 38-year-old man, presented a clinical condition compatible with the SUNCT (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing) syndrome. He presented a stabbing and intense daily pain located in the left pre-auricular and temporal regions. Each of these intense pain attacks lasted around one minute and presented a frequency of two to eight times per day. The pain was associated with ipsilateral lacrimation, conjunctival injection and rhinorrhea. MRI revealed a pituitary tumor with little suprasellar extent. The subjects serial assays of prolactin, GH, TSH and ACTH were within normal levels. Following transsphenoidal hypophysectomy, with complete removal of the tumor, the subject no more presented pain. The pathological diagnosis was non-secreting adenoma. Fourteen months after the surgery, he remains symptom-free.
