Endoscopic ultrasonography (EUS) investigates the inner side of the digestive tract and the adjacent structures, associating the endoscopic image to the ultrasonographic vision made by a miniaturized ultrasonograph. The technological innovations and a greater attention to the users, have made more complex the organization, the process and the management of the patients. In such panorama, the technical operator of endoscopy, is the competent professional that coordinates the whole necessary organization for diagnostic-therapeutic interventions assuring their feasibility, guaranteeing efficiency and safety of environmental hygiene and strumentario and a specific and competent relief approach to the patients and their relatives.

One hundred-twenty-six pediatricians were questioned about their attitudes concerning the practice of immunization, their feelings about the new vaccines (measles, mumps, german measles, hepatitis b) and about the pertussis vaccine. 80% of them reported that indications and contraindications were still unclear: Down's syndrome and atopic eczema are still thought to be real contraindications--despite the mass of papers suggesting that they are not so--, moreover 95% of the participants persists into the unnecessary evaluation of the antibody title following hepatitis b immunization. We conclude that it would be wise to periodically diffuse to pediatricians update recommendations about the extended immunization program, especially in our region, were still an high number of children are not properly immunized.
