BACKGROUND: Stroke has relevant morbidity and mortality despite appropriate treatments and early diagnosis. Beside common risk factors such as diabetes and atrial fibrillation, infections can be involved in stroke pathogenesis, probably causing a systemic release of cytokines and other inflammatory mediators, triggering a latent pro-thrombotic state or damaging the vascular endothelium. In other cases, infections can occur as stroke-like syndromes, requiring a high grade of suspicion to avoid a delay in establishing a correct diagnosis. RESULTS: Treatment of stroke or stroke-like syndromes of infectious origin can be difficult. When a previous infective event triggers stroke, Alteplase administration can be associated with a higher incidence of bleeding and the extension of the ischaemic area can be major than expected. On the other hand, when stroke is part of some infectious diseases' presentation as in endocarditis, bacterial or tuberculous meningitis and meningo-vascular syphilis, a correct diagnosis can be difficult. The management of these stroke-like syndromes is not standardised because common treatments proven to be effective for patients with stroke of vascular origin can worsen the prognosis, as it can be demonstrated after to be incorrect Alteplase administration to patients with endocarditis with septic embolism to the brain is associated with an increase of the risk of haemorrhage. CONCLUSIONS: Stroke or stroke-like syndrome of infectious origin can be observed in an important proportion of case presenting with sensory-motor deficit of unknown origin; their accurate diagnosis has a considerable impact in terms of treatment choices and outcome.

INTRODUCTION: The pregnancy-associated immunological and hormonal changes may alter the immune response to infectious agents, including hepatitis viruses. Therefore, this phenomenon may affect the clinical course and the outcome of acute viral hepatitis in pregnant women. EVIDENCE ACQUISITION: For this reason, we have focused on epidemiological and pathogenetic aspects of the fulminant liver failure caused by acute viral hepatitis reviewing PubMED in April of 2017. EVIDENCE SYNTHESIS: Although all the viruses might cause a fulminant acute viral hepatitis in a pregnant woman, the large majority of fulminant failure reported in the literature had been related to hepatits E virus (HEV) mainly and had been concentrated in Indian subcontinent and some African areas, whereas the problem seems to be very low or absent in the remaining geographical areas. However, the rate of maternal mortality due to fulminant E hepatitis may vary inside the endemic areas of India and Africa, likely due to the circulation of HEV genotypes with different degree of virulence. The other hepatitis viruses have not been reported to cause a greater risk for fulminant hepatitis in pregnant women respect to non-pregnant ones, except Herpes simplex virus, that has been associated to some cases of fatal hepatitis in absence of a prompt antiviral therapy. CONCLUSIONS: AVH should be considered when the pregnant woman develop fever, abdominal pain, malaise, nausea and anicteric hepatic dysfunction.
