From January 2017 to June 2018 more than 7000 measles cases were reported in Italy, of which more than 400 among unvaccinated healthcare workers. We described a measles outbreak occurred in Western Liguria, Italy, characterized by a high involvement of healthcare workers and hospital visitors. Suspected measles cases and data regarding vaccination status and clinical management of the patients were collected by reviewing 3 different surveillance systems: the routine mandatory notification system, the National Integrated Surveillance System for Measles and Rubella and the regional reference laboratory for measles diagnosis. Thirty-six cases were reported, with a median age of 31 years and >95% in unvaccinated subjects. One death occurred, 15 cases were hospitalized. Hospital transmission was confirmed or suspected in 12 cases; amongst this cases, 5 were healthcare workers (a gynaecologist, an obstetric nurse, a radiologist, a physiotherapist and a nurse working in an infectious disease ward), all certified unvaccinated. Phylogenetic analysis revealed the circulation of a single B3 genotype variant. Our experience highlighted the key role of nosocomial transmission and the need for targeted strategies, in particular (i) to implement a measles catch-up immunization campaign in susceptible groups, especially in healthcare workers, (ii) to intensify the check of immunisation status of healthcare workers and to offer vaccination for those who need it, (iii) to improve timeliness and completeness of surveillance systems. Efforts are needed to guarantee the safety of the hospital and the reliability of the healthcare workers. Only high vaccination coverage among HCWs can prevent the diffusion of measles in the hospital setting.

Colorectal cancer patients’ responses to neoadjuvant therapy undergo broad inter-individual variations. The aim of this systematic review is to identify a molecular signature that is predictive of colon cancer downstaging and/or downgrading after neoadjuvant therapy. Among the hundreds analysed in the available studies, only 19 messenger-RNAs (mRNAs) and six micro-RNAs (miRNAs) were differentially expressed in responders versus non-responders in two or more independent studies. Therefore, a mRNA/miRNA signature can be designed accordingly, with limitations caused by the retrospective nature of these studies, the heterogeneity in study designs and the downgrading/downstaging assessment criteria. This signature can be proposed to tailor neoadjuvant therapy regimens on an individual basis.

Influenza is one of the most common infectious diseases in travellers, especially in those returning from subtropical and tropical regions. In late June 2018 an influenza A(H1N1)pdm09 virus infection was diagnosed in a 36-years-old man, returned from a travel in Shanghai and hospitalized at the Ospedale Policlinico San Martino, Genoa, Italy, with a diagnosis of fever and an uncommon clinical presentation characterised by a persistent leukopenia. Phylogenetic analysis revealed a closeness with influenza A(H1N1)pdm09 strains circulating in the US in May-June 2018. Prompt recognition of influenza infection led to a proper case management, demonstrating the crucial role of the continuous influenza surveillance programme.
