ABSTRACT
Abstract Background Spontaneous intracranial hypotension (SIH) is a secondary cause of headache and an underdiagnosed disease. The clinical presentation can be highly variable. It typically presents with isolated classic orthostatic headache complaints, but patients can develop significant complications such as cerebral venous thrombosis (CVT). Objective To report 3 cases of SIH diagnosis admitted and treated in a tertiary-level neurology ward. Methods Review of the medical files of three patients and description of clinical and surgical outcomes. Results Three female patients with SIH with a mean age of 25.6 ± 10.0 years old. The patients had orthostatic headache, and one of them presented with somnolence and diplopia because of a CVT. Brain magnetic resonance imaging (MRI) ranges from normal findings to classic findings of SIH as pachymeningeal enhancement and downward displacement of the cerebellar tonsils. Spine MRI showed abnormal epidural fluid collections in all cases, and computed tomography (CT) myelography could determine an identifiable cerebrospinal fluid (CSF) leak in only one patient. One patient received a conservative approach, and the other two were submitted to open surgery with lamino-plasty. Both of them had uneventful recovery and remission in surgery follow-up. Conclusion The diagnosis and management of SIH are still a challenge in neurology practice. We highlight in the present study severe cases of incapacitating SIH, complication with CVT, and good outcomes with neurosurgical treatment.
Resumo Antecedentes Hipotensão intracraniana espontânea (HIE) é uma causa secundária de cefaleia e uma doença subdiagnosticada. A apresentação clínica pode ser muito variável. Tipicamente, se apresenta com queixas isoladas de cefaleia ortostática clássica, porém pode evoluir com complicações significativas como trombose venosa cerebral (TVC). Objetivo Relatar 3 casos de diagnóstico de hipotensão intracraniana espontânea manejados em uma enfermaria de neurologia de nível terciário. Métodos Revisão dos prontuários de três pacientes e descrição dos resultados clínicos e cirúrgicos. Resultados Três pacientes do sexo feminino com média de idade de 25.6 ± 10.0 anos. As pacientes apresentavam cefaleia ortostática e uma delas apresentou sonolência e diplopia devido a TVC. A ressonância magnética (RM) do encéfalo varia de achados normais até achados clássicos de HIE como realce paquimeníngeo e deslocamento inferior das tonsilas cerebelares. A RM da coluna mostrou coleções anormais de líquido epidural em todos os casos e a mielografia por tomografia computadorizada (TC) foi capaz de determinar fístula liquórica identificável em apenas uma paciente. Uma paciente recebeu abordagem conservadora e as outras duas foram submetidas a cirurgia aberta com laminoplastia. Ambas tiveram recuperação e remissão sem intercorrências no seguimento cirúrgico. Conclusão O diagnóstico e manejo da hipotensão intracraniana ainda são desafios na prática neurológica. Destacamos no presente estudo casos graves, complicação com TVC e bons resultados com tratamento neurocirúrgico.
ABSTRACT
ABSTRACT BACKGROUND: This study identified and summarized all Cochrane systematic reviews (SRs) on the effects of ten integrative practices that were recently added to the Brazilian public healthcare system (SUS). DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina (EPM), Universidade Federal de São Paulo (Unifesp). METHODS: Review of Cochrane SRs on the following interventions were identified, summarized and critically assessed: apitherapy, aromatherapy, bioenergetics, family constellation, flower therapy, chromotherapy, geotherapy, hypnotherapy, hand imposition or ozone therapy. RESULTS: We included a total of 16 SRs: 4 on apitherapy, 4 on aromatherapy, 6 on hypnotherapy and 2 on ozone therapy. No Cochrane SR was found regarding bioenergetics, family constellation, chromotherapy, clay therapy, flower therapy or hand imposition. The only high-quality evidence was in relation to the potential benefit of apitherapy, specifically regarding some benefits from honey dressings for partial healing of burn wounds, for reduction of coughing among children with acute coughs and for preventing allergic reactions to insect stings. CONCLUSION: Except for some specific uses of apitherapy (honey for burn wounds and for acute coughs and bee venom for allergic reactions to insect stings), the use of ten integrative practices that have recently been incorporated into SUS does not seem to be supported by evidence from Cochrane SRs.

Introdução Distúrbios neurológicos e neurocirúrgicos são altamente prevalentes no Brasil. O atendimento inicial é realizado por médicos generalistas, o que demonstra a importância dos estudos práticos e teóricos em neurologia e neurocirurgia nos cursos de graduação em medicina. Objetivos Descrever a escolha da especialidade médica dos formandos da Liga Acadêmica de Neurocirurgia da Escola Paulista de Medicina (LNC-EPM) e mapear a composição dos cursos de neurologia e/ou neurocirurgia e a presença de ligas acadêmicas dessas disciplinas nas escolas médicas do Brasil. Métodos Levantamento pessoal ou por rede social com todos os membros da liga de neurocirurgia da EPM de 2007 a 2015 quanto a conclusão do curso e a residência escolhida. Envio de um formulário online para todas as escolas médicas cadastradas no Conselho Federal de Medicina (CFM). Resultados e Discussão Cinquenta e sete graduandos de medicina já participaram da LNC-EPM, sendo que 45 já concluíram a graduação, 6 fizeram neurocirurgia e 5 neurologia. Conseguimos respostas de 128 das 173 escolas médicas cadastradas no CFM. Um total de 91% das escolas respondeu que possuem curso de neurologia estruturado. Esses cursos dividem-se em: 32 exclusivamente teóricos, com 12 abordando a neurocirurgia; 84 teórico-práticos, com 51 abordando a neurocirurgia. Apenas 19% das faculdades apresentam curso próprio estruturado de neurocirurgia, sendo que metade destes é apenas teórico. Um total de 66% das universidades tem liga acadêmica das disciplinas citadas. Conclusão Nota-se que a presença de ligas acadêmicas de neurologia e neurocirurgia em 66% das escolas médicas brasileiras é, muitas vezes, usada para suprir conhecimento teórico-prático que deveria ser abordado na graduação. Infelizmente, apenas 9,5% das escolas tem curso teórico-prático próprio de neurocirurgia na grade curricular, um fato que é preocupante devido à alta prevalência das doenças neurológicas na população.

ABSTRACT BACKGROUND: Probiotics have been used for a range of clinical situations and their use is strongly encouraged by the media worldwide. This study identified and summarized all Cochrane systematic reviews about the preventive effects of probiotics in clinical practice. DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina (EPM), Universidade Federal de São Paulo (Unifesp). METHODS: We included all Cochrane reviews on any probiotics when they were used as preventive interventions and compared with no intervention, placebo or any other pharmacological or non-pharmacological intervention. RESULTS: 17 Cochrane systematic reviews fulfilled our inclusion criteria and were summarized in this report. None of the reviews included in the present study provided high-quality evidence for any outcome. The benefits from use of probiotics included decreased incidence of antibiotic-associated diarrhea and Clostridium difficile-associated diarrhea; decreased incidence of upper respiratory tract infections and duration of episodes; decreased need for antibiotics and absences from school due to colds; and decreased incidence of ventilator-associated pneumonia. Probiotics seem to decrease the incidence of gestational diabetes mellitus, birthweight, risk of vaginal infection and incidence of eczema. CONCLUSION: Despite the marketing and the benefits associated with probiotics, there is little scientific evidence supporting the use of probiotics. None of the reviews provided any high-quality evidence for prevention of illnesses through use of probiotics. More trials are needed to gain better knowledge of probiotics and to confirm when their use is beneficial and cost-effective.
