Multisystem Inflammatory Syndrome in Children (MIS-C) is appearing in infants, children, and young adults in association with COVID-19 (coronavirus disease 2019) infections of SARS-CoV-2. Kawasaki Disease (KD) is one of the most common vasculitides of childhood. KD presents with similar symptoms to MIS-C especially in severe forms such as Kawasaki Disease Shock Syndrome (KDSS). The observed symptoms for MIS-C and KD are consistent with Mast Cell Activation Syndrome (MCAS) characterized by inflammatory molecules released from activated mast cells. Based on the associations of KD with multiple viral and bacterial pathogens, we put forward the hypothesis that KD and MIS-C result from antibody activation of mast cells by Fc receptorbound pathogen antibodies causing a hyperinflammatory response upon second pathogen exposure. Within this hypothesis, MIS-C may be atypical KD or a KD-like disease associated with SARS-CoV-2. We extend the mast cell hypothesis that increased histamine levels are inducing contraction of effector cells with impeded blood flow through cardiac capillaries. In some patients, pressure from impeded blood flow, within cardiac capillaries, may result in increased coronary artery blood pressure leading to aneurysms, a well-known complication in KD.
儿童多系统炎症综合征(MIS-C)出现在婴儿、儿童和年轻人中,与COVID-19(冠状病毒病2019)感染SARS-CoV-2有关。川崎病是儿童最常见的血管病之一。KD表现出与misc相似的症状,特别是在严重的形式,如川崎病休克综合征(KDSS)。观察到的MIS-C和KD的症状与肥大细胞活化综合征(MCAS)一致,其特征是活化肥大细胞释放炎症分子。基于KD与多种病毒和细菌病原体的关联,我们提出了KD和MIS-C是由Fc受体结合的病原体抗体激活肥大细胞导致第二次病原体暴露时的高炎症反应引起的假设。在这一假设中,misc可能是与SARS-CoV-2相关的非典型KD或KD样疾病。我们扩展肥大细胞假说,即增加的组胺水平诱导效应细胞收缩,阻碍血液通过心脏毛细血管。在一些患者中,心脏毛细血管内血流受阻的压力可能导致冠状动脉血压升高,导致动脉瘤,这是众所周知的KD并发症。

Introduction: During nonnutritive suck, infants must intermittently swallow. When a swallow occurs, it must interact with respiration in 2 main ways. We have previously labeled HOW the interaction occurs as “swallow-breath interaction” (SwBr), and WHERE in the respiratory cycle the swallow occurs as “phase of respiration incident to swallow” (POR). We have described SwBr and POR in preterm infants with and without bronchopulmonary dysplasia and term infants with neonatal abstinence syndrome. Objective: The objective of this work is to describe SwBr and POR in term infants (TRM) and compare those findings to our previous study of low-risk preterm (LRP) infants. Method: Suckle, swallow, nasal airflow and chest movement were recorded during nonnutritive suck in 12 TRM infants, collecting 94 swallows. SwBr and POR for each swallow were characterized by our previously described method. Generalized estimating equations were developed to relate the 3 types of SwBr and 5 types of POR to gender, birth weight, gestational age, postmenstrual age (PMA), and weeks post-first nipple feed. The percentages of SwBr and POR were compared to 16 LRP infants, with 176 swallows over 35 encounters. Results: TRM infants had more swallows with attenuated respiration (AR) with advancing weeks post-first nipple feed and fewer swallows occurring with obstructive apnea (OA) in males and with increasing birth weight. More swallows occurred at mid-expiration (ME) with increasing gestational age, PMA, and male gender and at mid-inspiration (MI) with increasing weeks post-first nipple feed. Fewer swallows occurred at MI in males. Infants in the LRP group studied before 35 weeks PMA were different from TRM infants but become indistinguishable from TRM infants as PMA approached 40 weeks. SwBr and POR in LRP infants progress towards improved feeding efficiency and safety. These results are similar to studies of nutritive feeding. Conclusion: SwBr and POR during nonnutritive suck in LRP infants become more like TRM infants with advancing PMA. Because the same brainstem centers are activated in both nutritive and nonnutritive suck, investigation of swallow during nonnutritive suck may provide similar information as nutritive feeding with easier analysis.
在非营养性吸吮过程中,婴儿必须间歇性吞咽。当吞咽发生时,它必须以两种主要方式与呼吸作用。我们之前将这种相互作用是如何发生的标记为“吞咽-呼吸相互作用”(SwBr),将吞咽在呼吸循环中发生的位置标记为“呼吸事件到吞咽的阶段”(POR)。我们描述了伴有或不伴有支气管肺发育不良的早产儿和伴有新生儿戒断综合征的足月婴儿的SwBr和POR。目的:本研究的目的是描述足月婴儿(TRM)的SwBr和POR,并将这些发现与我们之前对低危早产儿(LRP)的研究结果进行比较。方法:记录12例TRM患儿非营养性吸吮时的吸吮、吞咽、鼻气流及胸部运动,共收集94只燕子。每个燕子的SwBr和POR用我们之前描述的方法进行表征。建立了广义估计方程,将3种SwBr和5种POR与性别、出生体重、胎龄、经后年龄(PMA)和第一次母乳喂养后周数联系起来。对16只LRP婴儿的SwBr和POR的百分比进行了比较,这些婴儿在35次接触中有176只燕子。结果:TRM婴儿在第一次乳头喂养后数周内出现呼吸减弱(AR)的燕子较多,在男性和出生体重增加时出现阻塞性呼吸暂停(OA)的燕子较少。随着胎龄、PMA和男性的增加,更多的燕子发生在呼气中期(ME)和吸气中期(MI),随着第一次母乳喂养周数的增加。雄性燕子较少出现在MI。LRP组的婴儿在35周PMA之前与TRM组的婴儿不同,但在PMA接近40周时与TRM组的婴儿没有区别。低体重婴儿的SwBr和POR在提高喂养效率和安全性方面取得进展。这些结果与营养喂养的研究结果相似。结论:LRP患儿非营养性吸吮时SwBr和POR与TRM患儿相似,PMA进展。由于相同的脑干中枢在营养和非营养吸吮中都被激活,研究非营养吸吮过程中的吞咽可能提供与营养吸吮相似的信息,并且更容易分析。

This review’s purpose is to identify barriers on adherence of treatment guidelines in the management of pediatric Acute Otitis Media (AOM). The American Academy of Pediatrics (AAP) and American Academy of Family Physicians (AAFP) released revised AOM practice guidelines in 2013. These guidelines address diagnosis and management of AOM in healthy pediatric patients from six months to 12 years of age. AOM is the most common reason children are prescribed antibiotics1. Previous and continued antibiotic overuse presents increasing problems pertaining to antibiotic resistance, overall children’s health, and healthcare costs2. This guideline recommends treatment should be based on presenting signs and symptoms with severity being key in treatment, while conserving antibiotic use. This guideline includes diagnostic criteria, promotes the use of pneumatic otoscopy, and provides appropriate treatment regimens based on findings. Despite this, there is evidence that these guidelines are not being followed in multiple disciplines that provide care to this population. A comprehensive review of the literature obtained from several databases, produced 650 articles after inclusion and exclusion criteria was applied. In order to include the highest possible level of research, the articles were individually reviewed, and 19 articles were included in this review. Major barriers identified included factors regarding providers, parents, AOM severity and complications, concerns for follow-up care, and other clinical related factors. This literature review identified and compares these multidisciplinary barriers in hope of understanding reasons for the lack of guideline adherence and possibly help facilitate behavioral changes to improve patients’ wellbeing.
本综述的目的是确定在小儿急性中耳炎(AOM)治疗中遵守治疗指南的障碍。美国儿科学会(AAP)和美国家庭医生学会(AAFP)于2013年发布了修订后的AOM实践指南。这些指南涉及6个月至12岁健康儿童急性中耳炎的诊断和管理。急性中耳炎是给儿童开抗生素的最常见原因。过去和持续的抗生素过度使用带来了越来越多的与抗生素耐药性、儿童整体健康和医疗保健费用相关的问题2。本指南建议治疗应基于出现的体征和症状,治疗的关键是严重程度,同时保留抗生素的使用。本指南包括诊断标准,促进气动耳镜的使用,并根据发现提供适当的治疗方案。尽管如此,有证据表明,为这一人群提供护理的多个学科并没有遵循这些指导方针。在应用纳入和排除标准后,对从几个数据库获得的文献进行了全面审查,产生了650篇文章。为了纳入尽可能高水平的研究,对文章进行了单独审查,本综述纳入了19篇文章。确定的主要障碍包括有关提供者、家长、AOM严重程度和并发症、对后续护理的关注以及其他临床相关因素。本文献综述确定并比较了这些多学科障碍,希望了解缺乏指南依从性的原因,并可能有助于促进行为改变,以改善患者的健康。

Whole Sporozoite Vaccination: Duration between Successive Immunization Dictates the Fate Of Protective Immunity 全孢子子疫苗接种:连续免疫之间的时间决定了保护性免疫的命运

Whole sporozoite vaccination (WSV) is considered a gold standard for inducing and providing sterile protection against Plasmodium infection. Multiple doses of immunizations with radiation-attenuated sporozoites (RAS) is essential for establishing complete sterile protection against Plasmodium infection in mice as well as in humans. In our recently published article1, we have shown that the pattern of vaccination with RAS determines the degrees of protection in mice and frequent immunization with RAS in optimum time duration helps in generating minimum threshold liver-stage (LS) specific CD8+ T cell memory responses leading to sterile protection. Further, we have shown that the alterations in successive RAS immunization could possibly affect the induction of sterile protection. In summary, animals receiving four successive doses generated 100% sterile protection. However, three successive doses with the same parasite inoculum as four doses, could induce sterile protection in ∼50% mice. Interestingly, mice immunized with the same 3 doses, but with longer gap, could not survive the challenge.
全孢子子疫苗(WSV)被认为是诱导和提供针对疟原虫感染的无菌保护的金标准。用辐射减毒孢子子(RAS)进行多剂量免疫对于在小鼠和人类中建立针对疟原虫感染的完全无菌保护至关重要。在我们最近发表的文章1中,我们已经表明,RAS疫苗接种模式决定了小鼠的保护程度,在最佳时间内频繁接种RAS有助于产生最低阈值肝期(LS)特异性CD8+ T细胞记忆反应,从而导致无菌保护。此外,我们已经表明,连续RAS免疫的改变可能会影响无菌保护的诱导。总之,连续四次给药的动物产生了100%的无菌保护。然而,连续三次接种与四次接种相同的寄生虫,可以在50%的小鼠中诱导不育保护。有趣的是,小鼠接种相同的3次剂量,但间隔较长,无法存活。

Childhood Access to Technology and Cyberbullying 儿童获得技术和网络欺凌
Pub Date : 2019-03-01 DOI: 10.29245/2578-2940/2019/2.1136

Developmental factors and cyberbullying have not been a major focus in the field; most strikingly, the experiences that young children have with technology have been studied far less, relative to their adolescent peers. Prevalence estimates comparing younger and older children are problematic for several reasons; first, researchers have no consensus definition of cyberbullying, and second, prevalence estimates vary so widely that drawing conclusions is difficult. Access to technology is only another factor among several that likely influences the prevalence of cyberbullying, and it appears to vary with age. Access to cell phones and digital technology in adolescence is related to both victim availability and prevalence of cyberbullying itself. Among younger students, those under 12 years old, one study has found that cell phone ownership increases the risk of being both a cyberbully and a cyberbully/victim significantly. One factor that may mediate the impact of cell phone ownership is education on the appropriate and accurate use of digital technology. This type of education has been neglected in elementary schools, but evidence suggests it may be helpful in reducing cyberbullying.
发展因素和网络欺凌并不是该领域的主要焦点;最引人注目的是,与青少年相比,对儿童使用技术的体验的研究要少得多。由于几个原因,比较年幼儿童和大龄儿童的患病率估计存在问题;首先,研究人员对网络欺凌没有一致的定义,其次,对网络欺凌的患病率估计差异很大,很难得出结论。获取技术只是可能影响网络欺凌流行的几个因素中的另一个因素,而且似乎随年龄而变化。青少年使用手机和数字技术与受害者的可用性和网络欺凌本身的普遍性有关。一项研究发现,在12岁以下的年轻学生中,拥有手机大大增加了成为网络欺凌者和网络欺凌者/受害者的风险。可能调节手机拥有率影响的一个因素是对适当和准确使用数字技术的教育。这种类型的教育在小学一直被忽视,但有证据表明,它可能有助于减少网络欺凌。

My grey cells were amnestic about the pathophysiology of the disease of this not so common a case. My whole unit was instantly glued to their smartphones in a jiffy. They were uploading on google and enlightening me with quantum of information that the windows of my brain could not download it in one go. Whoa!!

Kratom: An Opioid-like Herbal Supplement Pediatricians Should Know About Kratom:一种儿科医生应该知道的阿片类草药补充剂
Pub Date : 2019-02-10 DOI: 10.29245/2578-2940/2019/1.1142

Kratom is a legal, widely-available herbal supplement with opioid-like properties increasingly used by those with opioid dependence to self-treat opioid withdrawal. Kratom binds to opioid receptors and can induce withdrawal, dependence, and toxicity. Classification of Kratom as an opioid is controversial. The search for non-opioid alternatives for the treatment of opioid dependence has intensified in the current opioid epidemic. Kratom is heavily advertised as one such safe non-opiate alternative and has been used by pregnant women with chronic opioid use resulting in neonatal abstinence syndrome. Kratom cannot be detected on routine toxicology screening. As kratom use becomes more widespread, pediatric populations will likely be impacted and pediatricians should familiarize themselves with its pharmacology and adverse effects to appropriately counsel parents and care for kratom-exposed patients. This article reviews kratom’s pharmacology, uses, potential benefits as a therapeutic, and risks for pediatric patients.
Kratom是一种合法的,广泛使用的草药补充剂,具有阿片类药物的特性,越来越多地被阿片类药物依赖者用于自我治疗阿片类药物戒断。Kratom与阿片受体结合,可引起戒断、依赖和毒性。克拉通作为阿片类药物的分类是有争议的。在当前阿片类药物流行的情况下,寻找治疗阿片类药物依赖的非阿片类药物替代品的工作已经加强。Kratom被大量宣传为一种安全的非阿片类药物替代品,并已被长期使用阿片类药物导致新生儿戒断综合征的孕妇使用。在常规毒理学筛查中无法检测到Kratom。随着kratom的使用越来越广泛,儿科人群可能会受到影响,儿科医生应该熟悉其药理学和副作用,以适当地咨询父母并照顾接触kratom的患者。这篇文章回顾了kratom的药理学,用途,作为治疗的潜在益处,以及对儿科患者的风险。

Kratom binds to opioid receptors and can induce withdrawal, dependence, and toxicity. Classification of Kratom as an opioid is controversial. The search for non-opioid alternatives for the treatment of opioid dependence has intensified in the current opioid epidemic. Kratom is heavily advertised as one such safe non-opiate alternative and has been used by pregnant women with chronic opioid use resulting in neonatal abstinence syndrome. Kratom cannot be detected on routine toxicology screening.

Preventing Hepatocellular Carcinoma: The Case for Childhood Intervention 预防肝细胞癌:儿童干预的案例
Pub Date : 2018-11-01 DOI: 10.29245/2578-2940/2018/6.1139

Hepatocellular carcinoma (HCC) is on the rise worldwide and in the US, and despite emerging treatment modalities, its overall prognosis remains poor; therefore, there is a need for preventing its development globally. The major factors contributing to HCC development, namely, infections with hepatitis B and hepatitis C viruses, alcoholic cirrhosis, aflatoxin-contaminated food, non-alcoholic fatty liver disease, metabolic syndrome, and smoking are modifiable; and prevention intervention can start in childhood. Vaccination for hepatitis B, screening for and treatment of hepatitis C and intravenous drug users, education to avoid fatty liver, alcoholism, and substance use were shown to be effective ways to curb HCC incidence. A focus on reducing early childhood adversity and training young children to make healthy decisions has been strongly recommended as a prevention strategy to reduce most of HCC risk factors.
肝细胞癌(HCC)在全球和美国呈上升趋势,尽管出现了新的治疗方式,但其总体预后仍然很差;因此,有必要防止其在全球范围内发展。导致HCC发展的主要因素,即乙型和丙型肝炎病毒感染、酒精性肝硬化、黄曲霉毒素污染的食物、非酒精性脂肪性肝病、代谢综合征和吸烟是可以改变的;预防干预可以从儿童时期开始。乙型肝炎疫苗接种、丙型肝炎和静脉注射吸毒者的筛查和治疗、避免脂肪肝、酗酒和药物使用的教育被证明是抑制HCC发病率的有效方法。强烈建议将重点放在减少儿童早期逆境和训练幼儿做出健康决定上,作为减少大多数HCC危险因素的预防策略。
