The aim of the current study was to prospectively determine the safety and the diagnostic accuracy of the 13C-UBT for the detection of H. pylori using the point-of-care continuous BreathID®Hp and the breath sampling bag test, BreathID®Hp Lab System, in a pediatric population. Fifty-three children performed the 13C-UBT via both the BreathID®Hp and the BreathID® Hp Lab System and were asked to provide a stool sample for conventional H. pylori antigen testing. BreathID®Hp sensitivity was 93.3% [95% CI (68.05%; 99.83%)] and specificity was 100% [95% CI (86.77%; 100.00%)] compared to stool antigen. The overall agreement in detection of H. pylori using the BreathID®Hp breath test versus the stool antigen test was 97.56% [95% CI (87.14%; 99.94%)]. BreathID®Hp Lab System sensitivity was 93.3% [95% CI (68.05%; 99.83%)] and specificity was 100% [95% CI (87.23%; 100.00%)] compared to stool antigen. The overall agreement in detection of H. pylori using the BreathID®Hp Lab System breath test versus the stool antigen test was 97.62% [95% CI (87.43%; 99.94%)]. One minor possibly related adverse event was recorded. Conclusions: Both the BreathID®Hp and the BreathID®Hp Lab System breath sample collection devices were safe and accurate in diagnosis of H. pylori infection in children. *Correspondence to: Sunny Z Hussain, Willis-Knighton Pediatric GI Specialist/ Willis-Knighton Health System, Shreveport, LA, USA, Tel: 318-212-5858; Fax 318212-5877; E-mail: Shussain@wkhs.com Tzippora Shalem, The Kamila Gonczarowski Institute of Gastroenterology, Shamir (Assaf Harofeh) Medical Center and the Sackler School of Medicine, Tel Aviv University, Israel, E-mail: tzippi.shalem@gmail.com","PeriodicalId":91786,"journal":{"name":"Pediatric dimensions","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67503922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several antenatal, perinatal and postnatal factors may contribute to the development of BPD [3,4]. It is postulated that early lung injury, inflammation, immaturity and arrestment of lung development play an important role in the pathogenesis of BPD [5,6]. Various strategies, including vitamin A and caffeine has been shown beneficial for prevention or treatment for BPD [7,8]. However, none of these therapies can eliminate this complication. Postnatal corticosteroids therapies, in particular, dexamethasone has been used in infant with evolving BPD and in infant with difficult extubation. However, systemic dexamethasone therapy in premature infants is not generally recommended because of the long-term adverse neurodevelopmental outcomes [9,10]. Inhaled steroids refer to less complication than systemic steroids, but technically difficult and the effects are limited [11]. Our research showed that, by using surfactant as vehicle, intratracheal administration of surfactant/ budesonide compared with surfactant alone significantly decreased the incidence of BPD or death without apparent immediate and long-term side effect [12]. This new therapeutic regimen is based on a physical phenomenon “Marangoni effect”’ that surfactant can be used as an effective vehicle to facilitate the delivery of a topical steroid, budesonide, to the lung periphery. Budesonide will remain in the lung [13] for some time and inhibit the lung inflammation. Pharmacokinetic study showed that more than 80% of budesonide remained in the lungs for up to 8 hours after intra-tracheal instillation of surfactant/budesonide [13]. With a proper concentration ratio between budesonide and surfactant (survanta/ budesonide ≥50, or curosurf/budesonide ≥160), addition of budesonide to surfactant would not affect the biophysical and chemical stability of surfactant. Preliminary follow up study showed insignificant side effect.","PeriodicalId":91786,"journal":{"name":"Pediatric dimensions","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67503665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cumulative risk scoring may be a useful tool to design more effective interventions to help high-risk young children reach their developmental potential in impoverished rural regions. Objective: To develop a risk score comprised of easily obtainable factors to design interventions and identify high-risk children who would most benefit from the interventions. Methods: Mother-child behavior interaction surveys and Ages and Stages Questionnaire, Third Edition (ASQ-3) developmental screens were completed in a convenience sample of 148 mothers with children aged 12-52 months in rural Guatemala. Associations between abnormal scores in the ASQ-3 developmental domains and demographic variables and mother-child interactions were examined. Scores were calculated by assigning 1 point for each of the included factors: 1) Maternal Demographic Risk score (DR): having no formal education, cannot read and write, having 3 or more children, and having 4 or more pregnancies; 2) Mother-Child Interaction score (MCI): sings songs, tells stories, plays with child with toys, converses with child while feeding, points to and names objects for child, and reads books to child; and 3) Combined Risk score (CR): combined two significant demographic elements and two significant negative mother-child interactions. Results: At baseline, 58% of children had abnormal scores in ≥1 ASQ-3 domain, and 35% in ≥2 domains. The probability of having ≥2 domains with abnormal scores increased significantly with an increasing DR score (OR, 1.46 [95% CI, 1.15-1.86] p<0.05) and an increasing CR score (OR, 2.08 [95% CI, 1.41-3.07], p<0.05). Conclusion: Rural Guatemalan children have high rates of ASQ-3 defined abnormal scores. A combined demographic and mother-child interaction cumulative risk index appears to be a useful tool to predict which children have abnormal scores across multiple domains. This CRI should be validated with more structured developmental testing that is not based on parent report. *Correspondence to: Stephen Berman, Director, Center for Global Health, Colorado School of Public Health, Mail Stop A090, 13199 E Montview Blvd, Suite 310, Aurora, CO 80045, USA, E-mail: stephen.berman@childrenscolorado.org Received: December 15, 2019; Accepted: December 27, 2019; Published: December 30, 2019 Introduction Child development is a global health priority. Approximately 4 in 10 children living in the developing world have developmental delays early in life. This risk of developmental delay is probably considerably higher for children born into rural impoverished communities [1].

It is further intended to determine if the functional classifications present a predictive factor for one or several types of CP established by the Surveillance of Cerebral Palsy in Europe (SCPE). An observational study was developed in schools in the Region of Murcia during the months of March to June 2018. Participants included children and adolescents from 3 to 18 years of age evaluated individually under the same conditions by a physiotherapist with more than 10 years of experience and following the available manuals. A high correlation between the scales was found. Spastic unilateral CP presented a greater prognosis in the development of the functional abilities described by the functional scales. The study shows how the classification systems complement each other to provide a better description of the functional profile of children with CP, and the four scales involve a predictive factor for some types of CP. *Correspondence to: Sergio Montero-Mendoza, Ministry of Education, Youth and Sports of the Region of Murcia (Spain), Physiotherapy Department, Catholic University of San Antonio (UCAM), Murcia, Spain, E-mail: smontero@ucam.edu","PeriodicalId":91786,"journal":{"name":"Pediatric dimensions","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67503503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
