Procedures for acute headache treatment in an emergency room

Importância do problema: cefaléia é dos sintomas mais comuns na prática clínica, responsável por cerca de 9% dos atendimentos em unidades primárias de saúde e por 1% a 3% dos atendimentos em unidades de emergência, acarretando, portanto, considerável impacto econômico sobre o serviço público de saúde.Comentários: a maioria das unidades de emergência, em nosso meio, não dispõem de drogas utilizadas em outros países para tratamento agudo da cefaléia, como os compostos ergotamínicosou triptanos. Os autores revisam aspectos diagnósticos e terapêuticos das cefaléias primárias agudas, propondo protocolos para seu tratamento em uma unidade de emergência.Headache is one of the most common symptoms in the clinical practice and it is responsible for about 9% of the appointments in primary care units and for 1% to 3% in the emergency rooms, leading to a considerable economic impact in the public health care system. Most of the emergency rooms in Brazil does not have drugs, like ergotics compounds and tryptans, used in other countries for the acute treatment of headache. The authors make a review of the diagnostic and therapeutic aspects of the acute primary headaches, suggesting protocols for its treatment in an emergency unit

Twenty years of coordination technologies: State-of-the-art and perspectives

Since complexity of inter- and intra-systems interactions is steadily increasing in modern application scenarios (e.g., the IoT), coordination technologies are required to take a crucial step towards maturity. In this paper we look back at the history of the COORDINATION conference in order to shed light on the current status of the coordination technologies there proposed throughout the years, in an attempt to understand success stories, limitations, and possibly reveal the gap between actual technologies, theoretical models, and novel application needs

Custos hospitalares das cefaléias agudas em uma unidade de emergência pública brasileira

Cefaléia é uma das queixas mais freqüentes na prática médica e causa bastante comum de atendimento em unidades de emergência, implicando custos consideravelmente altos. Foram estudados retrospectivamente os casos de cefaléia atendidos na Unidade de Emergência do Hospital das Clinicas de Ribeirão Preto (UE) no ano de 1996. Neste ano, 1254 pacientes procuraram a UE com queixa de cefaléia aguda, sendo que 64 necessitaram de internação. O custo estimado com o atendimento, investigação e tratamento clínico das cefaléias agudas foi da ordem de R$138,573.31 (US$ 76,985.17). Os gastos apenas com exames laboratoriais foram R$23,801.54 (US$ 13,223.07). Os custos cirúrgicos foram R$5,817.90 (US$ 3,232.17). Os custos totais foram RS$144,391.21 (US$ 80,217.34), o que equivale a R$115,14 (US$ 63.97) por paciente. Tais cálculos estimulam discussão adicional acerca de custos e eficácia do modelo de saúde vigente, em que os recursos financeiros são precários e as necessidades da população dependente do estado são proporcionalmente maiores

Thunderclap headache attributed to reversible cerebral vasoconstriction: view and review

Thunderclap headache attributed to reversible cerebral vasoconstriction (THARCV) is a syndrome observed in a number of reported cases. In this article we reviewed this new headache entity (idiopathic form) using the clinical-radiological findings of 25 reported patients. In this series of patients 72% were women, the mean age at the onset of first headache episode was 39.4 +/- 2.3 years. In addition to the sine quanon condition of being abrupt and severe (thunderclap) at the onset, the headache was usually described as being explosive, excruciating, or crushing. The feature of pulsatility, accompanied or not by nausea was described by 80% of the patients. Forty percent of the cases manifested vomiting and 24% photophobia. Usually the headache was generalized, and in three cases it was unilateral at least at the onset. In 21 of 25 patients (84%) there was at least one recurrence or a sudden increase in the intensity of the headache. A past history of migraine was present in 52% of the patients. Precipitating factors were identified in 56% of the patients. Sexual intercourse was described by six patients. Of the 25 patients with THARCV syndrome studied, 12 (48%) developed focal neurological signs, transitory ischemic attack (n = 1), or ischemic stroke (n = 11, 44%), and two (8%) of them manifested seizures. The THARCV syndrome is a neurological disturbance perhaps more frequent than expected, preferentially affecting middle aged female migraineurs, and having an unpredictable prognosis, either showing a benign course or leading to stroke
