Introduction: Given the lack of data, we aimed to explore which therapeutic endpoints pediatric patients with eosinophilic esophagitis (EoE) and their parents consider to be relevant. Methods: We created an educational brochure on EoE and a questionnaire, both of which were content-validated by pediatric patients and parents. Validated documents were sent to 112 patients and parents. They ranked the importance (5 levels) of short (during next 3 months) and long-term (≥1 year) treatment effect on symptoms, quality of life, endoscopic inflammation, stricture formation, histological inflammation, and fibrosis. Results: A total of 45 parents and 30 pediatric patients ≥11 years completed the questionnaires. Pediatric patients identified improvement in the following domains as most important in the short- and long-term, respectively: symptoms (73% vs. 77%), QoL (53% vs. 57%), histologic inflammation (47% vs. 50%), histologic fibrosis (40% vs. 33%), endoscopic inflammation (47% vs. 40%), and strictures (33% vs. 40%). Parents of children ≥11 years old classified improvement in the following domains as most important in the short- and long-term, respectively: symptoms (70% vs. 83%), QoL (63% vs. 80%), histologic inflammation (67% vs. 77%), histologic fibrosis (47% vs. 63%), endoscopic inflammation (77% vs. 80%), and strictures (40% vs. 53%). Agreement between caregiver and children on the short-term importance of treatment outcomes was as follows: symptoms (77%), QoL (40%), histologic inflammation and fibrosis (47% and 43%), endoscopic inflammation and strictures (50% and 40%). Conclusion: Pediatric patients and parents attributed most importance to improvement in symptoms and QoL. Agreement between parents and patients regarding therapy goals is limited.

Abstract There is a high frequency of diarrhea and vomiting in childhood. As a consequence the focus of the present review is to recognize the different body fluid compartments, to clinically assess the degree of dehydration, to know how the equilibrium between extracellular fluid and intracellular fluid is maintained, to calculate the effective blood osmolality and discuss both parenteral fluid maintenance and replacement.

Objective: Necrotizing enterocolitis of the neonate is an acute inflammatory intestinal disease that can cause necrosis and sepsis. Chorioamnionitis is a risk factor of necrotizing enterocolitis. The gut represents the biggest vagus-innervated organ. Vagal activity can be measured via fetal heart rate variability. We hypothesized that fetal heart rate variability can detect fetuses with incipient gut inflammation., Design: Prospective animal study., Setting: University research laboratory., Subjects: Chronically instrumented near-term fetal sheep (n = 21)., Measurements and Main Results: Animals were surgically instrumented with vascular catheters and electrocardiogram to allow manipulation and recording from nonanesthetized animals. In 14 fetal sheep, inflammation was induced with lipopolysaccharide (IV) to mimic chorioamnionitis. Fetal arterial blood samples were drawn at selected time points over 54 hours post lipopolysaccharide for blood gas and cytokines (interleukin-6 and tumor necrosis factor-α enzymelinked immunosorbent assay). Fetal heart rateV was quantified throughout the experiment. The time-matched fetal heart rate variability measures were correlated to the levels of interleukin-6 and tumor necrosis factor-α. Upon necropsy, ionized calcium binding adaptor molecule 1+ (Iba1+), CD11c+ (M1), CD206+ (M2 macrophages), and occludin (leakiness marker) immunofluorescence in the terminal ileum was quantified along with regional Iba1+ signal in the brain (microglia). Interleukin-6 peaked at 3 hours post lipopolysaccharide accompanied by mild cardiovascular signs of sepsis. At 54 hours, we identified an increase in Iba1+ and, specifically, M1 macrophages in the ileum accompanied by increased leakiness, with no change in Iba1 signal in the brain. Preceding this change on tissue level, at 24 hours, a subset of nine fetal heart rate variability measures correlated exclusively to the Iba+ markers of ileal, but not brain, inflammation. An additional fetal heart rate variability measure, mean of the differences of R-R intervals, correlated uniquely to M1 ileum macrophages increasing due to lipopolysaccharide., Conclusions: We identified a unique subset of fetal heart rate variability measures reflecting 1.5 days ahead of time the levels of macrophage activation and increased leakiness in terminal ileum. We propose that such subset of fetal heart rate variability measures reflects brain-gut communication via the vagus nerve. Detecting such noninvasively obtainable organ-specific fetal heart rate variability signature of inflammation would alarm neonatologists about neonates at risk of developing necrotizing enterocolitis and sepsis. Clinical validation studies are required.

Background and Aim: Sometimes, a temporary increase in alkaline phosphatase level is found in healthy infants and toddlers without evidence of liver or bone disease. The condition is customarily termed transient benign hyperphosphatasemia of infancy and early childhood. Most textbooks do not refer to the condition. The aim of the study was to promote broader awareness of transient benign hyperphosphatasemia., Methods: We completed a systematic review of the literature using the principles underlying the UK Economic and Social Research Council guidance on the conduct of narrative synthesis and the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement., Results: The 142 reports retained for analysis included 813 cases (male:female ratio 1.1:1.0): 80 in subjects older than 18 years and 733 in subjects 18 years or younger. The alkaline phosphatase ratio, calculated by dividing the measured level by the upper limit of normal, was ≥5.0 in ≈70% and the duration of the elevation was ≤4 months in 80% of the cases. Transient benign hyperphosphatasemia often followed a benign infection, but available data fail to demonstrate a causal link. The prevalence of transient benign hyperphosphatasemia ranged from 1.1% to 3.5% in infants 2 to 24 months of age., Conclusions: Transient benign hyperphosphatasemia is likely the most common cause of hyperphosphatasemia among healthy infants and toddlers. Sometimes it also occurs in older children and adults, indicating that the traditional term transient benign hyperphosphatasemia of infancy and early childhood may not be correct. The elevation in alkaline phosphatase persists for >4 months in ≈20% of the cases. Recognition of this benign condition is crucial to avoid unnecessary investigations.
