Migraine is a cyclic condition with attacks consisting mainly of intense headaches, sensory intolerance, and nausea or vomiting. Loss of consciousness during attacks is often attributed exclusively to a neurally mediated reflex to pain, although it may also be due to migraine's autonomic impairment, with cardiac conduction abnormalities, probably in relation to a degree of reduced sympathetic function. We report the case of a 51-year-old woman presenting episodes of syncope exclusively after vomiting during migraine attacks. ⋯ The patient was implanted with a pacemaker without further syncopes on subsequent attacks. This case highlights the importance of clinical suspicion and investigation of syncope during migraine attacks. Recurrent syncope during migraine should not be attributed to pain to avoid misdiagnosis and ensure the treatment of other important causes of syncope.

The Marburg and Ebola viruses belong to the Filoviridae family and are known to cause emerging zoonotic diseases. These viruses have a high case fatality rate and are easily transmissible from person to person, which makes them capable of triggering outbreaks, including in non-endemic regions, and are also considered agents of bioterrorism. Fruit bats are the natural reservoirs of these filoviruses. ⋯ However, for the Zaire Ebola virus (EBOV), monoclonal antibodies have already been licensed for treatment and post-exposure prophylaxis, in addition to three vaccines available. Due to the public health importance and the possibility of cases outside Africa, this review aims to improve clinical knowledge and the approach to suspected cases of FD. Improved surveillance and preparedness for potential global outbreaks are essential measures to effectively respond to these public health threats and to ensure that healthcare professionals are well-informed and prepared to deal with these diseases.
