Community-acquired pneumonia (CAP) remains a frequent cause of morbidity and mortality worldwide even in industrialised countries, and its incidence is highest among children aged <5 years. Over the last two years, three international guidelines have been updated with new evidence concerning the incidence, aetiology and management of childhood CAP, but there are still some major problems in standardisation. The main aim of this review is to consider the available data concerning the aetiology, diagnosis, evaluation of severity, and treatment of paediatric CAP. Analysis of the literature shows that there are a number of unanswered questions concerning the management of CAP, including its definition, the absence of a paediatric CAP severity score, the difficulty of identifying its aetiology, the emergence of resistance of the most frequent respiratory pathogens to the most widely used anti-infectious agents, and the lack of information concerning the changes in CAP epidemiology following the introduction of vaccines against respiratory pathogens. More research is clearly required in various areas, and further efforts are needed to increase vaccination coverage with the already available vaccines in order to reduce the occurrence of the disease.
we read with great interest the article by Pata et al. published online on June 2 nd in the Journal (1). Indeed, the current Covid‐19 epidemic in Italy and the associated, two months (March‐April) strict lockdown have impacted on the overall epidemiology and use of adult and pediatric medical resources –also due to dramatic changes in lifestyle.
Background and Objectives: Recent literature suggests that lung ultrasound might have a role in the diagnosis and management of bronchiolitis. The aim of the study is to evaluate the relationship between an ultrasound score and the clinical progression of bronchiolitis: need for supplemental oxygen, duration of oxygen therapy and hospital stay. Materials and Methods: This was a prospective observational single-center study, conducted in a pediatric unit during the 2017–2018 epidemic periods. All consecutive patients admitted with clinical signs of acute bronchiolitis, but without the need for supplemental oxygen, underwent a lung ultrasound in the first 24 h of hospital care. The lung involvement was graded based on the ultrasound score. During clinical progression, need for supplemental oxygen, duration of oxygen therapy and duration of hospital stay were recorded. Results: The final analysis included 83 patients, with a mean age of 4.5 ± 4.1 months. The lung ultrasound score in patients that required supplemental oxygen during hospitalization was 4.5 ± 1.7 (range: 2.0–8.0), different from the one of the not supplemented infants (2.5 ± 1.8; range: 0.0–6.0; p < 0.001). Ultrasound score was associated with the need for supplemental oxygen (OR = 2.2; 95% CI = 1.5–3.3; p < 0.0001). Duration of oxygen therapy was not associated with LUS score (p > 0.05). Length of hospital stay (coef. = 0.5; 95% CI = 0.2–0.7; p < 0.0001) correlates with LUS score. Conclusion: Lung ultrasound score correlates with the need of supplemental oxygen and length of hospital stay in infants with acute bronchiolitis.
Allergic colitis (AC) typically develops in the first weeks or months of life and is characterized by the presence of red blood in the stools of healthy breastfed or formula fed infants. In this paper, we describe a case of rectal bleeding in monozygotic preterm twins that was resolved with the introduction of a cow's milk protein-free diet (CMPFD). The occurrence of this disorder in monozygotic twins raises the question as to whether the underlying abnormality in the immune regulation, which leads to poor acquisition of tolerance to cow's milk proteins, might be inherited or environmentally acquired. The case also highlights the use of the probiotic Lactobacillus GG (LGG) in the treatment of allergic colitis.
Anesthetics and other products used during the perioperative period may influence immune function not only merely by reducing the HPA-axis stress response but also by directly modulating innate and adaptive immune responses. Most of the literature on the immune effects of anesthetics has been derived from in vitro or animal studies, due to the number of confounding variables in “real life” surgical settings. These immunosuppressive effects might not normally have clinical consequences for an immune-competent patient, but may act as important modifiers in postoperative morbidity and mortality. Furthermore, some inhibitory effects on neutrophil functions may provide a therapeutically beneficial effect under specific surgical clinical conditions, such as ischemia-reperfusion injury.
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.
