    Since the last eruption in 1888-90, the volcanic activity on Vulcano Island (Aeolian Archipelago, Italy) has been limited to fumarolic degassing. Fumaroles are mainly concentred at the active cone of La Fossa in the northern sector of the island and are periodically characterized by increases in the temperature as well as in the amount of both CO2 and He .Seismic background activity at Vulcano is dominated by micro-seismicity originating at shallow depth (<1-1.5 km) under La Fossa cone. This seismicity is related to geothermal system processes and comprises long period (LP) events. LPs are generally considered as the resonance of a fluid-filled volume in response to a trigger. We analyzed LP events recorded during an anomalous degassing period (August-October 2006) applying a high precision technique to define the shape of the trigger source. Absolute and high precision locations suggest that LP events recorded at Vulcano, during 2006, were produced by a shallow focal zone ca. 200 m long, 40 m wide and N30-40E oriented. Their occurrence is linked to magmatic fluid inputs that by modifying the hydrothermal system cause excitation of a fluid-filled cavity

    Systematic Data Monitoring and Analysis of Cardiovascular Off-label Prescriptions in Pediatrics: Focus on Angiotensin-Converting Enzyme Inhibitors (ACE-I) and Beta Blockers

    Introduction: Many efforts have been made to stimulate clinical trials (CTs) in pediatrics but most of the drugs are still authorized only in adults and used off-label in the pediatric population. Aim: To assess how widespread is the off-label prescription in Italy and to identify areas of unmet medical need by applying a model for the systematic collection and analysis of data. Methods: A study was performed using 2015 data from the Italian Medicines Utilization Monitoring Centre Health Database (OsMed). A study sample of 3,726,583 pediatric patients, was considered. Cardiovascular drugs were selected for this study. Assessment of the off-label use, the analysis of the pharmacovigilance signals, a bibliographic research and the analysis of ongoing CTs were carried out. Results: In 2015, 8,544 pediatric patients received treatment with a cardiovascular drug. Angiotensin converting enzyme inhibitors (ACE-I) followed by beta&nbsp;blockers agents are the most prescribed molecules. Eight molecules were selected and an in-depth analysis conducted. The PhV network showed only one record of adverse reaction as off-label in 2015. The results show several therapeutic areas of use in pediatrics. Conclusion: Off-label in pediatrics is largely widespread in Europe and US and our results show it is also present in Italy. Molecules selected are used off-label for therapeutic areas such as oncologic, hematological and rare diseases. Results of pharmacovigilance suggests underreporting. The analysis carried out in this study could be an open track for a systematic monitoring activity and of interest for prescribers, pediatricians and other healthcare professionals during the clinical practice
