Pilot study on compulsory vaccination coverage

The disappearance of diphtheria and poliomyelitis is the best evidence of the efficacy of the vaccination strategies adopted in Italy. The active offer of the prophylaxis, reinforced by law, has characterised the operational aspects of the strategy. The active surveillance system is the main tool to take under control the effectiveness of health services responsible for vaccination. This system could be more easily implemented if the health services will be given a specific software aiming to handle and evaluate vaccination registers. The present pilot study, performed in the regions Marche and Sardegna, is an example of active surveillance and it is based on the ARVA software produced by the Istituto Superiore di Sanità. The results show a good level of coverage (> 95%) within the second year of life. Unsatisfactory results were obtained on the timing of vaccinations, as recommended by the vaccination schedule, mostly for the third doses.     

Non-coronary cardiac events,younger age,and IVIG unresponsiveness increase the risk for coronary aneurysms in Italian children with Kawasaki disease

Coronary cardiac allograft vasculopathy versus native atherosclerosis: difficulties in classification

Cardiac allograft vasculopathy is regarded as a progressive and diffuse intimal hyperplastic lesion of arteries and veins that leads to insidious vessel narrowing and to allograft ischemic disease, such as acute myocardial infarction or sudden cardiac death. The coronary lesions in transplanted hearts are considered as a particular type of arteriosclerosis with many similarities but also significant differences compared to native coronary atherosclerosis. It is particularly difficult for pathologists to systematically classify the lesions and to elucidate their origins, since over time, the allograft immune responses cause vascular pathology characterized by not only the onset of de novo fibrocellular lesions but also remodeling of already-existing native atherosclerotic lesions in the donor heart. Intraplaque hemorrhages, which result from newly formed leaky microvessels, may cause rapid increase of stenosis and generate a substrate for plaque destabilization. Comparing cardiac allograft vasculopathy from explanted hearts at autopsy with native coronary atherosclerosis from hearts removed at transplantation has revealed that ongoing intraplaque hemorrhages are also an important feature of cardiac allograft vasculopathy and may be important factors in the rapid progression of cardiac allograft vasculopathy.
