The incidence of cancer is higher in transplant patients than in the normal population, mostly due to the assumption of immunosuppressants able to reduce the possibility of rejection. In addition, immunocompromised patients have a greater susceptibility to EBV, HPV and HIV, infectious agents that by themselves may favor the onset of malignancies. Post-transplant lymphoproliferative diseases (PLDs) are among the most frequent neoplasms in transplant patients which like other aggressive neoplasms may be identified by the [18f] fluoro-D-deoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). ⋯ In the present study, FDG-PET/CT examination was of great use for an early identification and for an early treatment of PTLDs and other neoplasms.

This study is a meta-analysis of the published studies on the relationship between methylenetetrahydrofolate reductase (MTHFR) C667T polymorphism and the risk of late- onset Alzheimer 's disease (LOAD) in Italian cohorts. ⋯ The present meta-analysis showed only trend of association between MTHFR C677T polymorphism and LOAD in Italian population; however, it also demonstrated an increased susceptibility of LOAD in patients having MTHFR 677TT genotype. Further studies are needed to establish whether MTHFR polymorphisms can be used as non-invasive biomarker for LOAD.
