Macrophage activation syndrome (MAS) is a reactive form of hemophagocytic lymphohistiocytosis, complicating Still's disease, both in paediatric and adult patients. In this work, we aimed to investigate clinical picture and outcome of Still's disease patients developing MAS. We performed a retrospective analysis of patients, both paediatrics and adults, affected by Still's disease attending our department. During the follow-up, each patient was investigated for MAS occurrence and possible predictors, clinical and laboratory factors, were analysed. We evaluated 50 patients affected by Still's disease, 21 paediatric and 29 adult patients. Ten patients experienced MAS (five adult and five paediatric patients) and its development significantly reduced the survival rate when compared with patients without this complication (p < 0.0001). The analysis of possible predictors showed that high-value systemic score (p = 0.03) and high levels of serum ferritin (p = 0.002) were independently associated with an increased likelihood of MAS. MAS occurrence significantly reduced survival rate in both paediatric and adult patients affected by Still's disease. The high levels of serum ferritin and an elevated systemic score, at the time of diagnosis, were significantly associated with MAS.
on behalf of the Surveys in Pediatric Infectious Diseases study group∥∥∥∥Background: Antibiotics represent the most widely prescribed drugs in children worldwide, both in hospital and community settings. A comprehensive approach to understanding the reasons and determinants of antibiotic prescription in the pediatric age is needed. This study aimed to assess parents' attitudes and perspectives about antibiotic use.
Methods: Prospective observational study was conducted in all ItalianRegions between February 1 and April 30, 2020, using a standardized questionnaire. Results: Six thousand six hundred twenty-five parents from all Italian regions completed the survey. Seventy-six percent of parents were aware that only bacteria are the target of antibiotics, but 92.9% knew that the antibiotic has no direct effect on fever. Antibiotic self-prescription (10.4%) or by remote consultation by phone call (19.9%) or message (9.6%) were relatively common. Ninety-three percent of parents were aware that excessive use of antibiotics could select resistant bacteria and 84.7% of them knew that they could actively fight antibiotic resistance. About two thirds of participants (66.1%) received information on antibiotic resistance from their family pediatrician. Parents born of Italy or those with lower income had a higher probability of having less information from pediatricians or knowledge of proper antibiotic use. Discussion: Our study suggests that parents' knowledge and attitudes toward antibiotic use and prescription are improving compared with previous studies, while there is still a gap regarding antibiotic resistance, particularly on practices that can reduce its burden. Our study's negative finding is that families from low-income settings or those born abroad have significantly more misconceptions about important antibiotic practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
