During the past 10years, Clostridium difficile infections (CDI) have become a major public health challenge. Their epidemiology has changed with a rise in the number of cases and an increase in severe episodes. Recurrence and failure of conventional treatments have become more common. ⋯ Fidaxomicin is a novel antibiotic drug with interesting features, including an efficacy not inferior to vancomycin and a lower risk of recurrence. Finally, for multi-recurrent forms, fecal microbiota transplantation seems to be the best option. We present the available data in this review.

Hereditary hemorrhagic telangiectasia (HHT), is a rare, hereditary vascular dysplasia, characterized by recurrent epistaxis, mucocutaneous telangiectasias and visceral arteriovenous malformations. The vascular endothelial growth factor VEGF seems to play a crucial role in the pathogenesis of this disease. Recently bevacizumab, a humanized monoclonal VEGF inhibitor, has shown promise in treating patients with HHT. ⋯ The use of modulators of angiogenesis such as bevacizumab is a possible therapeutic target in HHT.
