Abstract Background The diagnostic and treatment strategies for children are limited because of the small number of children with COVID-19. A large proportion of infected children are asymptomatic or have mild symptoms. We report our experience regarding clinical characteristics, laboratory, radiologic findings, and outcomes of children with COVID-19. Materials and Methods This retrospective single-center study was conducted on children with COVID-19. The data on epidemiologic characteristics, clinical features, laboratory, and radiologic findings of patients were extracted from the hospital information management system records, and patients' forms filled upon admission. Results The median age of children was 121 months, 46.8% of the patients were females and 53.2% were males. Of the 581 children assessed, a total of 222 (38.2%) had positive test results; 69 of them (31.1%) were asymptomatic. The median absolute lymphocyte and eosinophil counts were statistically significantly lower in symptomatic children (p = 0.001; p = 0.02). Neutrophil lymphocyte ratio was statistically significantly higher in the symptomatic children (p = 0.001). Of 72 computed tomography scans, 35 (48.6%) were normal, and only 29 (40%) were consistent with classic/probable/indeterminate COVID-19 predominant pattern. Conclusion Our results showed a few laboratory abnormalities in asymptomatic polymerase chain reaction positive children; therefore, unnecessary investigation might be avoided and clinicians should consider clinical symptoms.
摘要背景 儿童的诊断和治疗策略受到限制,因为患有新冠肺炎的儿童人数很少。很大一部分受感染的儿童没有症状或症状轻微。我们报告了我们在新冠肺炎儿童的临床特征、实验室、放射学检查结果和结果方面的经验。材料和方法 这项回顾性单中心研究是针对新冠肺炎儿童进行的。从医院信息管理系统记录中提取患者的流行病学特征、临床特征、实验室和放射学检查结果数据,并在入院时填写患者表格。后果 儿童的中位年龄为121个月,46.8%的患者为女性,53.2%为男性。在接受评估的581名儿童中,共有222名(38.2%)的检测结果呈阳性;其中69例(31.1%)无症状。有症状儿童的淋巴细胞和嗜酸性粒细胞绝对计数中位数在统计学上显著降低(p = 0.001;p = 0.02)。有症状儿童的中性粒细胞淋巴细胞比率在统计学上显著较高(p = 在72次计算机断层扫描中,35次(48.6%)正常,只有29次(40%)符合经典/可能/不确定的新冠肺炎主要模式。结论 我们的研究结果显示,在无症状聚合酶链式反应阳性儿童中存在一些实验室异常;因此,可以避免不必要的调查,临床医生应该考虑临床症状。

Abstract Croup is an acute inflammatory condition affecting upper airways and commonly seen in children with younger age group. Croup is most commonly due to acute viral infection and rarely because of bacterial and atypical agents. Here, we report a 3-month-old child who presented to us with classic signs and symptoms of croup and was also positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Child's mother also tested positive for SARS-CoV-2. SARS-CoV-2 infection presenting with stridor and croup is very rare and probably represents a new manifestation which should be considered in a young infant presenting with croup.
group是一种影响上呼吸道的急性炎症,常见于年龄较小的儿童。该组最常见的是由于急性病毒感染,很少是因为细菌和非典型病原体。在这里,我们报告了一个3个月大的婴儿,他向我们提出了典型的体征和症状,并且对严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)也呈阳性。孩子的母亲也被检测出SARS-CoV-2阳性。SARS-CoV-2感染表现为喘鸣和组群是非常罕见的,可能代表了一种新的表现,应考虑在出现组群的年幼婴儿。

Abstract Objective Ultrasound (US) is an established imaging modality in adult sports medicine but is not commonly used in the diagnosis of pediatric sports conditions, such as Little League shoulder (LLS). This study was conducted to determine the reliability of US measurement of width of the physis at the proximal humerus in diagnosed LLS and to compare US to radiography (RA) in detecting a difference between the affected (dominant) (A) and unaffected (U) shoulders. Materials and Methods Ten male baseball players diagnosed with LLS were enrolled in the study. US images of the proximal humeral physis at the greater tuberosity of both shoulders were obtained by an US-trained sports medicine physician, and the physeal width was measured. Blinded to prior measurements, a separate physician performed measurements on the stored US images. Measurements were compared with RA on the anteroposterior (AP) view for both A and U at the time of the initial visit and for A at follow-up. Results The physeal width (mm) at A and U at the initial visit averaged 5.94 ± 1.69 and 4.36 ± 1.20 respectively on RA, and 4.15 ± 1.12 and 3.40 ± 0.85 on US. Median difference of averaged US measurements between A and U at initial evaluation was 0.75 mm (p = 0.00016). A linear model showed US measurements to be predictive of RA on A (R2 = 0.51) and U (R2 = 0.48). Conclusion US was able to reliably measure the width of the proximal humeral physis and detect a difference between A and U. US correlated well with RA (standard for LLS). US should be considered by the US-trained physician for the diagnosis of LLS.
【摘要】目的超声(US)是成人运动医学中公认的影像学手段,但在儿童运动疾病的诊断中并不常用,如小联盟肩(LLS)。本研究旨在确定超声测量肱骨近端骨骺宽度在LLS诊断中的可靠性,并将超声与x线摄影(RA)在检测受影响(主)(a)肩和未受影响(U)肩之间的差异方面进行比较。材料与方法选取10名诊断为LLS的男性棒球运动员为研究对象。由美国训练的运动医学医师获得双肩大结节处肱骨近端体的美国图像,并测量体宽度。不知道之前的测量结果,另一位医生对存储的美国图像进行测量。将A和U在初次就诊时以及A在随访时的正位(AP)视图测量值与RA进行比较。结果初诊时A、U处骨骺宽度(mm) RA平均值分别为5.94±1.69、4.36±1.20,US平均值为4.15±1.12、3.40±0.85。A和U在初始评估时平均US测量值的中位数差为0.75 mm (p = 0.00016)。线性模型显示US测量值可预测A (R2 = 0.51)和U (R2 = 0.48)的RA。结论US能可靠地测量肱骨近端物理宽度,并能检测出a和u之间的差异。US与RA (LLS的标准)有良好的相关性。在美国接受培训的医生诊断LLS时应考虑US。

Abstract Background Growth potential is influenced by race, ethnicity, and environmental factors and assessment of growth using standardized charts is important for quality improvement initiatives in health care delivery and public health interventions of any nation. Objective This article aims to develop regional gestational age and gender-specific reference for birth weight and to compare it with published literature. Methodology This study was conducted in a teaching hospital in Puducherry, India and included 2,507 singleton babies. Babies with major congenital anomalies, maternal chronic illness, and nonavailability of first trimester dating scan were excluded. Detailed anthropometric measurement was done for these babies by single investigator as per established norms, their gestation- and sex-specific mean weight and weight percentiles were calculated and compared with existing data. Results Both 10th and 90th percentiles were lower across all gestational ages compared with existing international standards. The proportion of late preterm and term small for gestational age (SGA) babies was 23% using Fenton-2013 reference chart, 14% using Intergrowth-21 chart, and 10% using the current study data (p < 0.0001). The proportion of large for gestational age (LGA) babies was 8.5%, using study data. Mean birth weight of male and female term babies born to primiparae were significantly higher compared with multiparae (p = 0.03 and 0.02, respectively). Conclusion Indian babies may be overdiagnosed as SGA or underdiagnosed as LGA based on existing western standards in which our patient population is underrepresented. There is a need for gestational age-, gender-, and parity-specific regional growth charts for better characterization of anthropometric measures of Indian babies.
摘要背景 增长潜力受种族、民族和环境因素的影响,使用标准化图表评估增长对于任何国家的医疗保健和公共卫生干预的质量改进举措都很重要。客观的 本文旨在开发地区胎龄和出生体重的性别参考,并将其与已发表的文献进行比较。方法论 这项研究是在印度普杜切里的一家教学医院进行的,包括2507名单身婴儿。排除患有严重先天性畸形、母亲患有慢性疾病和无法进行孕早期约会扫描的婴儿。由一名研究人员根据既定规范对这些婴儿进行了详细的人体测量,计算了他们的妊娠期和性别特异性平均体重和体重百分比,并与现有数据进行了比较。后果 与现有的国际标准相比,所有胎龄的第10和第90个百分位数都较低。使用Fenton-2013参考图,晚期早产和足月小于胎龄(SGA)婴儿的比例为23%,使用Intergrowth-21图为14%,使用当前研究数据为10%(p < 0.0001)。根据研究数据,妊娠期大婴儿(LGA)的比例为8.5%。初产妇所生的男性和女性足月婴儿的平均出生体重明显高于多产妇(p = 分别为0.03和0.02)。结论 根据现有的西方标准,印度婴儿可能被过度诊断为SGA,也可能被低估为LGA,在这些标准中,我们的患者群体代表性不足。为了更好地描述印度婴儿的人体测量指标,需要制定特定于胎龄、性别和胎次的区域生长图。

Abstract A very limited amount of data are available regarding the follow-up of celiac disease (CD) treatment in Iran. The aim of this study is to investigate antitissue transglutaminase (atTG) normalization interval and the associated factors in CD patients. This retrospective study included CD patients enrolled in Children's Medical Center, Tehran University of Medical Sciences. The initial atTG titer and histological evaluation (with Marsh grade ≥2) were recorded. The atTG titer was assessed in each follow-up until the time of normalization where children were strictly on gluten-free diet. The age at the time of diagnosis, gender, Marsh grade at the time of diagnosis, other comorbidities, and family history of CD patients were recorded to determine the association of these factors with antibody normalization interval. In total, 71 patients were recruited in the study of which 34 (47.89%) subjects had atTG level below 20 U/mL at the average interval of 31.36 ( ±  2.89) months (95% confidence interval: 25.7–37.02). There was no significant difference between the antibody normalization interval and different age ranges and Marsh grade. Cox regression demonstrated that gender, age ranges, Marsh grade, positive family history of CD, and the presence of comorbidities did not significantly predict longer antibody normalization interval.
关于伊朗乳糜泻(CD)治疗的随访数据非常有限。本研究旨在探讨乳糜泻患者抗组织转谷氨酰胺酶(atTG)正常化间隔及相关因素。本回顾性研究纳入了德黑兰医科大学儿童医学中心的乳糜泻患者。记录初始atTG滴度和组织学评价(Marsh分级≥2)。在每次随访中评估atTG滴度,直到儿童严格采用无谷蛋白饮食的正常化时间。记录患者诊断时的年龄、性别、诊断时的Marsh分级、其他合并症、家族史,以确定这些因素与抗体正常化间隔的关系。研究共纳入71例患者,其中34例(47.89%)患者atTG水平低于20 U/mL,平均间隔31.36(±2.89)个月(95%可信区间:25.7-37.02)。抗体正常化间隔与不同年龄范围及Marsh分级无显著差异。Cox回归分析显示,性别、年龄范围、Marsh分级、CD家族史阳性、是否存在合并症并不能显著预测更长的抗体正常化时间间隔。

Abstract Many antenatal sonographies are out of indication and may be asked due to mothers' requests or other factors. However, these features are not fully understood. This study aimed to assess the association of sociodemographic, obstetric, and attitudinal factors that may affect the number of ultrasound scans. In a cross-sectional study in six hospitals affiliated with Mashhad University of Medical Sciences, 360 mothers who had a delivery or were expected to be near childbirth were enrolled in the study. The mean number of sonographies was compared between different study variables by using Mann–Whitney, Kruskal–Wallis, and Pearson's Chi-squared tests. Moreover, the Spearman Rho test was used to assess the correlation between different variables and the number of sonographies. Totally, 300 cases remained in the study. The mean age of the mothers was 25.95 ± 4.77 years, and the average number of ultrasonographies was 3.50 ± 1.35. In case of sociodemographic features, the level of education (r = 0.23; p < 0.001) and several recent miscarriages (r = 0.140; p = 0.01) were correlated with number of sonographies. However, there was no association between maternal age and marriage age with several sonographies (p > 0.05). Furthermore, mothers with higher family income (p = 0.010), those with medical insurance (p = 0.010), those who had male fetuses (p = 0.020), those who were clerk or student (p = 0.003), and those who were not aware of the sonography risks (p = 0.020) had more requests for sonography. It seems that financial factors and awareness of sonography risks play an essential role in sonography requests by mothers.
摘要许多产前超声检查是不适应症的,可能是由于母亲的要求或其他因素而被询问的。然而,这些特征并没有被完全理解。本研究旨在评估可能影响超声扫描次数的社会人口统计学、产科和态度因素之间的关系。在马什哈德医学科学大学附属的六家医院进行的一项横断面研究中,360名分娩或预计即将分娩的母亲参与了这项研究。使用Mann–Whitney、Kruskal–Wallis和Pearson的卡方检验对不同研究变量之间的声像图平均数量进行比较。此外,Spearman-Rho检验用于评估不同变量与声像图数量之间的相关性。共有300例病例仍在研究中。母亲的平均年龄为25.95岁 ± 4.77岁,平均超声检查次数为3.50次 ± 1.35.就社会人口特征而言,教育水平(r = 0.23;p  0.05)。此外,家庭收入较高的母亲(p = 0.010),有医疗保险的人(p = 0.010),有男性胎儿者(p = 0.020),职员或学生(p = 0.003),以及那些没有意识到超声检查风险的人(p = 0.020)有更多的超声检查要求。财务因素和对超声检查风险的认识似乎在母亲提出超声检查要求中起着至关重要的作用。

Furthermore, mothers with higher family income (p = 0.010), those with medical insurance (p = 0.010), those who had male fetuses (p = 0.020), those who were clerk or student (p = 0.003), and those who were not aware of the sonography risks (p = 0.020) had more requests for sonography. It seems that financial factors and awareness of sonography risks play an essential role in sonography requests by mothers.","PeriodicalId":41283,"journal":{"name":"Journal of Child Science","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49366530","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}

Abstract Magnetic resonance imaging (MRI) scans for children are a challenge for anesthesiologists since the child must be sedated enough to stand still. But anesthetic drugs used for sedation might have serious side effects and monitorization resources and accessibility to the patient during MRI scan is limited. We retrospectively examined 977 pediatric patients' files who had MRI scans in our hospital. We observed that children received one of the four combinations of anesthetic drugs: group 1 received midazolam, propofol, and ketamine; group 2 received midazolam and ketamine; group 3 received midazolam and thiopental; and group 4 received midazolam and propofol combination for sedation. The patients in group 1 had significantly higher vomiting rates than the patients in group 4 (p = 0.005). We observed bronchospasm in patients in group 1 (p = 0.006) and group 3 (p = 0.001), more than in patients in group 4. Nausea and vomiting ratios were lower in group 4. In patients with nausea and vomiting within a week after the procedure, statistically significant lower neutrophil–lymphocyte ratio values (p = 0.012) were observed. All four anesthetic combinations used in the trial provided safe anesthesia for the children, during the MRI scan. The anesthetic choice must be made according to the procedure time and patient's comorbidities. In this trial, we observed minimum side effects with midazolam and propofol combination.
摘要儿童核磁共振成像(MRI)扫描对麻醉师来说是一个挑战,因为儿童必须服用足够的镇静剂才能站立不动。但用于镇静的麻醉药物可能会有严重的副作用,MRI扫描期间患者的监测资源和可及性有限。我们回顾性地检查了977名在我们医院进行MRI扫描的儿科患者的档案。我们观察到,儿童接受了四种麻醉药物组合中的一种:第一组接受咪唑安定、丙泊酚和氯胺酮;第2组给予咪唑安定和氯胺酮;第3组给予咪唑安定和硫喷妥钠;第4组给予咪唑安定和丙泊酚联合镇静。第1组患者的呕吐率明显高于第4组患者(p = 0.005)。我们观察到第1组患者的支气管痉挛(p = 0.006)和第3组(p = 0.001),高于第4组患者。第4组恶心呕吐率较低。在术后一周内出现恶心和呕吐的患者中,中性粒细胞-淋巴细胞比值降低具有统计学意义(p = 0.012)。试验中使用的所有四种麻醉剂组合在MRI扫描期间为儿童提供了安全的麻醉。必须根据手术时间和患者的合并症来选择麻醉剂。在本试验中,我们观察到咪唑安定和丙泊酚联合用药的副作用最小。

Abstract Globally, infective group A rotavirus (RVA) enteric infection in children culminates in acute diarrheal disease, severe dehydration, and mortality in children under the age of 5 years, particularly in sub-Saharan Africa. This research sought to determine the prevalence of RVA diarrhea among children aged below 5 years in Ondo state, as one of the necessary frameworks before instituting a vaccine campaign, and to expand knowledge on the epidemiology of RVA diarrhea in Nigeria. In a cross-sectional descriptive study between October 2012 and September 2014, convenience sampling was adopted to obtain demographic information, clinical details, and stool samples from accented under five children who sought treatment for acute gastroenteritis at designated hospitals in Akure and Owo, Nigeria. A total of 390 stool samples were collected from children with acute diarrhea and tested for VP6 RVA antigen using enzyme immunoassay. Data generated were analyzed using descriptive statistics and chi-square at α 0.05. From the 390 children hospitalized for diarrhea, 240 samples (240/390; 61.5%) were from males, while 150 samples (150/390; 38.5%) were from females, representing a male:female ratio of 1.6:1. RVAs were found in 24.2% (58/240) males and 28% (42/150) females, giving a male-female ratio of 1:1.2 and total prevalence of 25.6% (100/390). RVA infection was inversely proportional to the age as a rate of 11.8% was observed in children aged above 36 months and 31.8% (35/110) in children 7 to 12 months, while the highest rate (45.7%) was among children ≤ 6 months old. No significant difference was found (chi-square = 0.712) in the induction of diarrhea in children from Akure and Owo, neither was there any significant difference in the rates of infection between the boys and girls in Akure (chi-square = 0.576) nor in Owo (chi-square = 0.333). Seasonal association (chi-square = 5.802) in RVA infection was observed in the rainy season of year 2013/2014 period. RVA diarrhea occurred year-round at a prevalence of 25.6%, predominantly in females. A seasonal fluctuation was observed in the rainy and dry seasons of the 2-year period. RVA diarrhea occurred predominantly in children aged below 18 months of age, and may thus help in determining the optimal period/schedule of any immunization program.
摘要在全球范围内,儿童感染性A组轮状病毒(RVA)肠道感染最终导致5岁以下儿童急性腹泻、严重脱水和死亡,特别是在撒哈拉以南非洲。这项研究旨在确定翁多州5岁以下儿童RVA腹泻的流行率,作为开展疫苗接种活动前的必要框架之一,并扩大对尼日利亚RVA腹泻流行病学的了解。在2012年10月至2014年9月的一项横断面描述性研究中,采用方便抽样的方法,从尼日利亚阿库雷和奥沃的指定医院寻求急性肠胃炎治疗的五岁以下儿童中获取人口统计信息、临床细节和粪便样本。共收集了390份急性腹泻儿童的粪便样本,并使用酶免疫测定法检测VP6 RVA抗原。使用描述性统计和卡方(α0.05)对生成的数据进行分析。在390名因腹泻住院的儿童中,240份样本(240/390;61.5%)来自男性,150份样本(150/390;38.5%)来自女性,男女比例为1.6:1。在24.2%(58/240)的男性和28%(42/150)的女性中发现RVA,男女比例为1:1.2,总患病率为25.6%(100/390)。RVA感染率与年龄成反比,36个月以上儿童为11.8%,7-12个月儿童为31.8%(35/110),而儿童感染率最高(45.7%) ≤ 6个月大。未发现显著差异(卡方 = 0.712)在阿库尔和奥沃儿童腹泻的诱导中,阿库尔男孩和女孩的感染率也没有任何显著差异(卡方 = 0.576)也不在Owo(卡方 = 0.333).季节关联(卡方 = 5.802)。RVA腹泻全年发生率为25.6%,主要发生在女性中。在2年的雨季和旱季观察到季节性波动。RVA腹泻主要发生在18个月以下的儿童中,因此可能有助于确定任何免疫计划的最佳时期/时间表。

Abstract Celiac disease (CD) is a multisystemic autoimmune disorder triggered by gluten, and the only known remedy available for this malady is a gluten-free diet (GFD). Therefore, we performed a systematic review to correlate the influence of different factors in compliance to a GFD. We searched PubMed database, from inception to April 2019. As inclusion criteria we considered population under 18 years, confirmed diagnosis of CD without related comorbidities and the study objective being the factors affecting compliance to a GFD. The variables compared were age, parent's education level, parental knowledge about CD, family type, celiac association membership, quality of life, and perception of difficulties in maintaining a GFD. We identified 1,414 articles, 35 articles were eligible for full text assessment and 12 were included in the study since they studied similar variables. Our work has found some limitations namely a variety of methods to assess GFD compliance, a limiting definition of compliance, a parental bias in data, an absence of standardization in age categories, and a majority of studies being observational in their nature. Age as well as parental knowledge of CD and family type are key factors in pediatric GFD compliance. Nevertheless environmental, social, and family factors were also related with compliance. Further studies are needed to fully disclose the causality relation between these factors and compliance.
摘要腹腔疾病(CD)是一种由麸质引发的多系统自身免疫性疾病,唯一已知的治疗方法是无麸质饮食(GFD)。因此,我们进行了一项系统审查,以将不同因素对GFD依从性的影响联系起来。我们搜索了PubMed数据库,从成立到2019年4月。作为纳入标准,我们考虑了18岁以下的人群,确诊为CD且无相关合并症,研究目标是影响GFD依从性的因素。比较的变量包括年龄、父母的教育水平、父母对CD的了解、家庭类型、腹腔协会成员、生活质量和对维持GFD困难的感知。我们确定了1414篇文章,35篇文章符合全文评估条件,12篇文章被纳入研究,因为它们研究了类似的变量。我们的工作发现了一些局限性,即评估GFD依从性的各种方法、依从性的有限定义、父母在数据中的偏见、年龄类别缺乏标准化,以及大多数研究都是观察性的。年龄以及父母对CD和家庭类型的了解是儿童GFD依从性的关键因素。然而,环境、社会和家庭因素也与依从性有关。需要进一步的研究来充分揭示这些因素与依从性之间的因果关系。
