Causes of fever in returning TRAVELERS: A EUROPEAN MULTICENTER prospective cohort study.
Etiological diagnosis of febrile illnesses in returning travelers is a great challenge, particularly when presenting with no focal symptoms [acute undifferentiated febrile illnesses (AUFI)], but is crucial to guide clinical decisions and public health policies. In this study, we describe the frequencies and predictors of the main causes of fever in travelers. ⋯ Over 40% of returning travelers with AUFI were diagnosed with malaria or dengue, infections that can be easily diagnosed by rapid diagnostic tests. Arboviruses were the most common cause of AUFI (above malaria) and most cases were diagnosed during Aedes spp. high season. This is particularly relevant for those areas at risk of introduction of these pathogens. Empirical antibiotic regimens including doxycycline or azithromycin should be considered in patients with AUFI, after ruling out malaria and arboviruses.

Tolerance and humoral immune response to the yellow fever vaccine in sickle cell disease children treated with hydroxyurea: a multicentre prospective study.
Sickle cell disease (SCD) children are frequent travellers to countries where yellow fever (YF) is endemic, but there are no data regarding the safety and immunogenicity of the vaccine in such children treated with hydroxyurea (HU). The main objective of this study was to compare the tolerance and immune response to YF vaccination in SCD children treated or not with HU. ⋯ YF vaccination seems to be safe and efficient in SCD children treated with HU. Considering the potential risk of severe complications in cases of YF while travelling in Africa for those patients, the benefit-to-risk ratio argues for YF vaccination in all SCD children. Control of a protective antibody titre may also be useful to ascertain an adequate response in those treated with HU.

Schistosomiasis, strongyloidiasis and Chagas disease: the leading imported neglected tropical diseases in Italy.
In recent years, an increasing number of individuals affected by neglected tropical diseases (NTDs) have been observed in Italy, due to migration, international travels and climate changes. Reliable data on the current NTD epidemiology in Italy and the health system preparedness on this issue are not available. ⋯ This survey showed how some NTDs, such as schistosomiasis and strongyloidiasis, are becoming more common in Italy, due to multiple components. A list of seven key actions was proposed, in order to improve diagnosis, management and control of NTDs in Italy.

Delay in schistosomiasis diagnosis and treatment: a multicenter cohort study in Italy.
Barriers to access to care, different diagnostic strategies and low awareness remain challenging issues in the fight against schistosomiasis.Our study aims to examine management of schistosomiasis in migrants attending large tertiary hospitals in Italy, in order to call for a comprehensive approach. ⋯ In our centers, a high proportion of patients were tested late after arrival, and most of them presented with clinical apparent disease. Well-defined strategies and implementation of recent guidelines are needed to improve early diagnosis and to overcome heterogeneity of practice.
