The susceptibility of healthy children to neostigmine by hypodermic injection was studied in controlled experiments on 45 children ranging in age from 1 month to 12 years. Minimum effective doses (MED) of neostigmine were determined by their effect in stimulating salivary and sweat glands, and in increasing gastrointestinal motility. The MED of neostigmine for stimulation of salivation is in all age groups smaller (by 6 to 38 per cent) than the MED increasing gastrointestinal motility. The average MED either for glandular (.025 to .036 mg./kg.) or gastrointestinal (.036 to .045 mg./kg.) activity fails to show significant differences among the various age groups when expressed in terms of body weight. Exceptions were found exclusively in children weighing more than 30 kg. The findings do not support the view that a physiologic vagotonia is present in infants.

The susceptibility of apparently healthy children of all age groups to atropine by oral and subcutaneous administration was studied in carefully controlled experiments on 129 children. The minimal effective dose (MED) of atropine was determined by its effect in suppressing sialorrhea elicited either mechanically by chewing gum and/or pharmacologically by subcutaneous injection of methacholine. Variations in individual susceptibility to atropine are large in all age groups and independent of the route of administration (oral, hypodermic.) The average MED/kg. body weight following oral administration is somewhat smaller in infants of 1 to 12 months and children from 12 to 36 months (0.16 and 0.14 mg./kg., respectively) than in older children in the age groups of 3 to 6 years and 6 to 12 years (0.22 and 0.20 mg./kg., respectively). Comparable results are obtained by hypodermic administration. The ratio between the MED by mouth and the MED by hypodermic injection is approximately 3:1 in all age groups. The determination of the susceptibility of children of various ages of atropine fails to adduce evidence supporting the assumption of an increased resistance to atropine or of a physiologic vagotonia in infants. The relation of the MED of atropine in apparently healthy children to the doses recommended in pediatric therapy is discussed. The calculation of the dosage of atropine by body weight is recommended.

Predictable serum levels of streptomycin can be obtained by calculating dosage on a basis of mg./unit body weight. Dosage can be determined in this fashion in all age groups. The serum streptomycin levels following single intramuscular injections of 6.6, 11.0, and 15.4 mg./kg. body weight are graphically illustrated. The serum level following a single intramuscular injection falls more slowly during the newborn period. This is probably the result of dehydration and consequent low urine output. Healthy children with apparently normal kidney function show little accumulation of streptomycin in the serum during intermittent intramuscular injection at the three and six hour intervals. Eleven mg./kg. body weight every six hours is recommended as a satisfactory dosage schedule when it is desirable to keep the blood streptomycin level constantly above 5 µ. per milliliter.

Liver Elastography

Abstract Purpose Liver elastography is increasingly being applied in screening for and follow-up of pediatric liver disease, and has been shown to correlate well with fibrosis staging through liver biopsy. Because time is of the essence when examining children, we wanted to evaluate if a reliable result can be achieved with fewer acquisitions. Materials and Methods 243 healthy children aged 4–17 years were examined after three hours of fasting. Participants were divided into four age groups: 4–7 years; 8–11 years; 12–14 years and 15–17 years. Both two-dimensional shear wave elastography (2D-SWE; GE Logiq E9) and point shear wave elastography (pSWE; Samsung RS80A with Prestige) were performed in all participants, while transient elastography (TE, Fibroscan) was performed in a subset of 87 children aged 8–17 years. Median liver stiffness measurement (LSM) values of 3, 4, 5, 6, 7, and 8 acquisitions were compared with the median value of 10 acquisitions (reference standard). Comparison was performed for all participants together as well as within every specific age group. We investigated both the intraclass correlation coefficient (ICC) with absolute agreement and all outliers more than 10 %, 20 % or ≥ 0.5 or 1.0 kPa from the median of 10 acquisitions. Results For all three systems there was no significant difference between three and ten acquisitions, with ICCs ≥ 0.97. All systems needed 4 acquisitions to achieve no LSM deviating ≥ 1.0 kPa of a median of ten. To achieve no LSM deviating ≥ 20 % of a median of ten acquisitions, pSWE and TE needed 4 acquisitions, while 2D-SWE required 6 acquisitions. Conclusion Our results contradict recommendations of 10 acquisitions for pSWE and TE and only 3 for 2D-SWE.

According to the authors, rationing the age-related EEG parameters in children should be based on personal psychical characteristics. A comparative analysis of personal psychical characteristics and electroencephalographic data was carried out in 300 apparently healthy children aged 3-15 years. According to this principle, two subgroups of conditionally healthy children in each age group were singled out: 1) with an immature attention function and 2) with an increased anxious background that do not reach the pathological level. Registration and analysis of EEG was performed by the Neurokariograf computer complex (MBN, Moscow) using mathematical processing methods.The EEG interpretation was based on the principle of assessing the functional state of a child's brain using a three-component model according to: 1) wakefulness level and its dissociation, 2) severity of signs of the EEG neurotic pattern, 3) directionality of formation of traits of the system-functional brain organization (severity of signs functional hypofrontality).lt was found the presence of EEG signs was indicative of a lower level of wakefulness in children with an immature function of attention in all age groups, compared with the indicators of the average population of group and children with an increased background of anxiety. Children with an increased background of anxiety have a tendency to prevalence and excessive spatial synchronization of the alpha rhythm. ln healthy children, the fact of a decrease in wakefulness and the presence of signs of anxiety in the clinic and in EEG patterns indicates individual personalities and should not be considered as pathology.

Abstract Objectives It is unclear whether body weight status (underweight/normal weight/overweight/obese) is associated with allergic disease. Our objective was to investigate the relationship between body weight status (body mass index; BMI) and atopic allergic disease in prepubertal children, and to compare children with atopic allergic diseases with non atopic healthy children. Methods A prospective cross sectional study of 707 prepubertal children aged 3–10 years was performed; the participants were 278 atopic children with physician-diagnosed allergic disease (allergic rhinitis and asthma) (serum total IgE level >100 kU/l and eosinophilia >4%, or positivity to at least one allergen in skin test) and 429 non atopic healthy age- and sex-matched controls. Data were collected between December 2019 and November 2020 at the Pediatric General and Pediatric Allergy Outpatient Clinics of Bezmialem Vakıf University Hospital. Results Underweight was observed in 11.6% of all participants (10.8% of atopic children, 12.2% of healthy controls), and obesity in 14.9% of all participants (18.0% of atopic children, 12.8% of controls). Obese (OR 1.71; 95% CI: 1.08–2.71, p=0.021), and overweight status (OR 1.62; 95% CI: 1.06–2.50, p=0.026) were associated with an increased risk of atopic allergic disease compared to normal weight in pre-pubertal children. This association did not differ by gender. There was no relationship between underweight status and atopic allergic disease (OR 1.03; 95% CI: 0.63–1.68, p=0.894). Conclusions Overweight and obesity were associated with an increased risk of atopic allergic disease compared to normal weight among middle-income and high-income pre pubertal children living in Istanbul.

Plasma Leptin

Mechanisms regulating circulating leptin are incompletely understood. We developed a radioimmunoassay for mouse leptin to examine the influence of age, dietary fat content, and fasting on plasma concentrations of leptin in the background strain for the ob/ob mouse, the C57BL/6J mouse. Plasma leptin increased with age [5.3 +/- 0.6 ng/ml at 2 mo (n = 23) vs. 14.2 +/- 1.6 ng/ml at 11 mo (n = 15), P < 0.001]. Across all age groups (2-11 mo, n = 160), log plasma leptin correlated with body weight (r = 0.68, P < 0.0001), plasma insulin (r = 0.38, P < 0.001), and amount of intra-abdominal fat (r = 0.90, P < 0.001), as revealed by magnetic resonance imaging. Plasma leptin was increased by a high-fat diet (58% fat for 10 mo) and reduced by fasting for 48 h. The reduction of plasma leptin was correlated with the reduction of plasma insulin (r = 0.43, P = 0.012) but not with the initial body weight or the change in body weight. Moreover, the reduction in plasma leptin by fasting was impaired by high-fat diet. Thus plasma leptin in C57BL/6J mice 1) increases with age or a high-fat diet; 2) correlates with body weight, fat content, and plasma insulin; and 3) is reduced during fasting by an action inhibited by high-fat diet and related to changes of plasma insulin.

Objective.To determine the accuracy of the Broselow Tape (BT) versions 2007 and 2011 in estimating weight among pediatric population.Methods.A cross-sectional study was conducted at King Fahad Medical City and six schools across Riyadh province on 1–143-month-old children. BT 2007 and 2011 estimated weights were recorded. Both tapes via the child’s height produce an estimated weight, which was compared with the actual weight.Results.A total of 3537 children were recruited. The height (cm) of the subjects was97.7±24.1and the actual weight (kg) was16.07±8.9, whereas the estimated weight determined by BT 2007 was15.87±7.56and by BT 2011 was16.38±7.95. Across all the five age groups, correlation between actual weight and BT 2007 ranged between 0.702 and 0.788, while correlation between actual weight and BT 2011 ranged between 0.698 and 0.788. Correlation between BT 2007 and BT 2011 across all the five age groups ranged from 0.979 to 0.989. Accuracy of both the tape versions was adversely affected when age was >95 months and body weight was >26 kilograms.Conclusions.Our study showed that BT 2007 and 2011 provided accurate estimation of the body weight based on measured body height. However, 2011 version provided more precise estimate for weight.
