Background: In the neonatal period, cortisol concentrations are expected to increase during significant stress and are important for survival. Extreme preterm infants may develop adrenal insufficiency in the early neonatal period. Cortisol is 90% bound to cortisol binding globulins (CBG) in the circulation; therefore measurements of plasma cortisol can be compromised by conditions that alter CBG levels. Measurement of free cortisol is the best indicator of adrenal glucocorticoid secretion and can be determined in the saliva. Few studies have been reported on salivary cortisol determination in the neonatal period and particularly, extremely premature infants. Methods: There were 65 infants (36 males). Mean gestation 25.3 ± 1.3 weeks. We obtained early morning plasma and salivary cortisol sampling before day 5 of postnatal age from extremely premature babies less than 28 weeks gestation. Saliva was obtained using 4 standard universal swabs by placing one swab at a time in the infant's mouth for 1-2 min. No salivary stimulants were used. Salivary cortisol was measured by competitive ELISA using a commercially available kit SLV-2930 (DRG, Germany) according to the manufacturer's instructions. Plasma cortisol was measured using DPC Immulite 2000 using a solid phase 2 site chemiluminescent immunometric assay. Results: Mean plasma cortisol levels were 400 nmol/L ± 42.8 SEM, and mean salivary cortisol levels were 127.5 nmol/L ± 66.5 SEM. Plasma cortisol was positively correlated with salivary cortisol (r=0.41, p<0.001). Conclusion: The study showed a reasonable correlation between salivary and plasma cortisol concentrations obtained early in the morning in the extremely preterm infants.
背景:在新生儿时期,皮质醇浓度预计会在显著的压力下增加,对生存很重要。极早产儿可能在新生儿早期出现肾上腺功能不全。在循环中,皮质醇90%与皮质醇结合球蛋白(CBG)结合;因此,血浆皮质醇的测量可能会受到改变CBG水平的条件的影响。游离皮质醇的测量是肾上腺糖皮质激素分泌的最佳指标,可在唾液中测定。很少有研究报道唾液皮质醇测定在新生儿时期,特别是极早产儿。方法:65例婴幼儿(男36例)。平均妊娠25.3±1.3周。我们采集了小于28周妊娠的极早产儿在出生后第5天的清晨血浆和唾液皮质醇样本。使用4个标准的通用拭子获得唾液,每次将一个拭子放入婴儿口中1-2分钟。不使用唾液刺激剂。唾液皮质醇采用竞争性ELISA法测定,使用市售试剂盒SLV-2930 (DRG,德国),根据制造商的说明。血浆皮质醇测量使用DPC Immulite 2000采用固相2位点化学发光免疫测定法。结果:平均血浆皮质醇水平为400 nmol/L±42.8 SEM,平均唾液皮质醇水平为127.5 nmol/L±66.5 SEM。血浆皮质醇与唾液皮质醇呈正相关(r=0.41, p<0.001)。结论:本研究显示极早产儿清晨唾液和血浆皮质醇浓度之间存在合理的相关性。

Aim: To assess the usefulness of postnatal renal ultrasound in newborns with isolated external ear anomalies in the presence of a normal renal ultrasound on the routine surveillance prenatal ultrasound. Study design: 80 consecutive patients with isolated minor ear anomalies were collected retrospectively starting from December 2008 till February 2011; the prevalence of renal anomalies detected in postnatal ultrasound in those patients was compared with that detected in prenatal ultrasound. Results: Our study included only 64 patients with isolated minor ear anomalies who have prenatal and postnatal ultrasound while 16 patients were excluded (14 patients with no recorded data regarding the prenatal ultrasound, one patient with associated imperforate anus and another patient with unilateral undescended testes). Out of the 64 patients, only one patient was reported to have unilateral pyelactasis in prenatal ultrasound but was reported to be normal on postnatal ultrasound. Otherwise all prenatal renal ultrasound findings were normal on both the prenatal and postnatal renal ultrasound findings. Conclusion: There is no difference in the detection of renal anomalies between postnatal renal ultrasound in infants with isolated minor ear anomalies compared with that found on routine prenatal ultrasound.
目的:探讨在常规监测的产前超声检查中,在肾超声正常的情况下,产后肾超声对孤立外耳异常新生儿的诊断价值。研究设计:回顾性收集自2008年12月至2011年2月连续80例孤立性轻微耳部异常患者;将产前超声检查与产后超声检查中肾脏异常的发生率进行比较。结果:本研究仅纳入了64例经产前和产后超声检查的孤立性轻微耳部异常患者,排除了16例患者(14例无产前超声记录,1例伴有肛门闭锁,1例伴有单侧睾丸隐睾)。在64例患者中,只有1例患者在产前超声中被报道为单侧肾盂瘘,但在产后超声中被报道为正常。此外,所有产前和产后肾脏超声检查结果均正常。结论:孤立性轻微耳部异常婴儿出生后肾超声与常规产前超声对肾脏异常的检出率无差异。

Background: The aims of this study were to determine prognostic factors and to devise a new scoring system for neurodevelopmental outcomes in infants with neonatal seizures. Methods: A retrospective review of medical records was performed for infants treated for neonatal seizures from March 2010 to December 2015 at the neonatal intensive care unit at Haeundae Paik Hospital. Neurologic outcomes were assessed at the post-conceptional age of 24 months. To assess the risk factors associated with poor neurologic outcomes, various factors including clinical characteristics, EEG findings, and the results from neuroimaging work-ups were analyzed with univariate and multiple logistic regression analyses (SPSS version 18.0). Results: Of the 174 enrolled infants, 57 (32.8%) showed abnormal neurologic outcomes. Seven potential predictors of adverse outcomes, selected by binary logistic regression analysis, were used to devise a scoring system. These included birth weight, time of onset, EEG findings, neuroimaging results, seizure type and severity and etiology. The variables were assigned binary scores with a total arithmetic composite score ranging from 0 to 7. A cutoff score of ≥ 3 provided the greatest sensitivity and specificity. Normalization or persistent normal findings at follow-up EEG within 3 months after seizure on-set were also associated with neurologic outcomes (p<0.05). Conclusion: We propose scoring system uses seven variables to provide early prognostic information on unfavorable neurodevelopmental outcomes in infants with neonatal seizures and reliably predicts long-term neurologic outcomes at the time of seizure onset.
背景:本研究的目的是确定新生儿癫痫发作的预后因素,并设计一种新的神经发育结局评分系统。方法:回顾性分析2010年3月至2015年12月在白海云台医院新生儿重症监护室治疗的新生儿癫痫患儿的医疗记录。在受孕后24个月评估神经系统预后。为了评估与神经系统预后不良相关的危险因素,采用单变量和多元logistic回归分析(SPSS 18.0版)对临床特征、脑电图结果和神经影像学检查结果等各种因素进行分析。结果:174例入组婴儿中,57例(32.8%)出现神经系统预后异常。通过二元逻辑回归分析选择七个潜在的不良结果预测因子,设计一个评分系统。这些包括出生体重、发病时间、脑电图结果、神经影像学结果、癫痫发作类型、严重程度和病因。这些变量被赋以二进制分数,算术综合总分从0到7。临界值≥3提供了最大的敏感性和特异性。癫痫发作后3个月内随访脑电图恢复正常或持续正常也与神经系统预后相关(p<0.05)。结论:我们提出的评分系统使用7个变量提供新生儿癫痫发作不利神经发育结局的早期预后信息,并可靠地预测癫痫发作时的长期神经预后。

A Review of Anesthetic Effects on the Developing Brain - Animal versus Human Models 麻醉对发育中的大脑的影响——动物与人模型的比较
Pub Date : 2016-11-21 DOI: 10.4172/2167-0897.1000240
F. Quraishi, Ming Xiong
In the last 30 years a large amount of data, both animal and human, has come out indicating that perhaps the most commonly used general anesthetics (inhaled anesthetics such as nitrous oxide and iso/sevo/desflurane, but also propofol) may have an effect on the neurodevelopment of an unborn fetus. The neurotoxic effects of volatile anesthetics have been tested numerous times in animal models ranging from rats to primates, and there is a large amount of reliable data which have confirmed that these agents do, in fact, cause interruption and even degeneration of neuronal development, with clinically significant cognitive and behavioural changes neonatal. Does this data apply to the human model?
在过去的30年里,大量的动物和人类数据表明,也许最常用的全身麻醉剂(吸入麻醉剂,如氧化亚氮和异/七/地氟醚,还有异丙酚)可能对未出生胎儿的神经发育有影响。挥发性麻醉药的神经毒性作用已经在从大鼠到灵长类动物的动物模型中进行了多次测试,并且有大量可靠的数据证实,这些药物确实会导致神经元发育中断甚至退化,并在临床上引起新生儿显著的认知和行为改变。这些数据适用于人体模型吗?

Patent Ductus Arteriosus (PDA) is present in 40-60 percent of preterm infants with its incidence inversely proportional to the gestational age. Management of PDA in extreme prematurity and extremely low birth weight infants is controversial specially with newer literature showing no significant benefits in long term outcomes in infants who were treated as compared to those who were not treated. Further the mortality and morbidities in preterm infants may not be entirely related to PDA as previously ascribed. Hence there is controversy as to which preterm infants benefit from treatment, when should they be treated and which treatment modalities should be used. We have reviewed the current literature to bring out the controversies in the answer to these questions.
动脉导管未闭(PDA)存在于40- 60%的早产儿,其发病率与胎龄成反比。极端早产和极低出生体重婴儿的PDA管理是有争议的,特别是最新的文献显示,与未接受治疗的婴儿相比,接受治疗的婴儿在长期预后方面没有显著的益处。此外,早产儿的死亡率和发病率可能并不完全与PDA有关。因此,对于哪些早产儿能从治疗中受益、何时应该治疗以及应该使用哪种治疗方式,存在争议。我们回顾了目前的文献,提出了这些问题的答案的争议。

MECP2 Mutations Associated with Rett Syndrome - Molecular Approaches 与Rett综合征相关的MECP2突变-分子方法
Pub Date : 2016-11-04 DOI: 10.4172/2167-0897.1000237
V. Ramakrishnan
Rett syndrome (RTT) is defined as a monogenic, X-linked neurological disorder leading to delayed neurodevelopment in females and characterized by scoliosis, seizures, microcephaly, intellectual disability, repetitive hand movement, impaired sleep, excessive saliva, autonomic symptoms, typically little or no verbal skills. Worldwide RTT has been estimated to affect 1 in every 10-15,000 live female births in all ethnic groups [1]. Methyl-CpG binding protein 2 (MECP2) located at chromosomal position q28, containing 4 exons with five protein domains, was identified as the gene responsible for RTT in the year 1999 [2]. This gene was identified by the binding of methyl-CpG binding domain (MBD) to nucleic acid sequences that are being methylated at cytosine. Subsequently, the functional domains such as the nuclear localization signal (NLS) and transcriptional repression domain (TRD) were also identified [3]. MECP2 protein involve in various functions such as chromatin architecture, heterochromatin rearrangement, nuclear organization, regulates splicing and DNA methylation [4].
Rett综合征(RTT)被定义为一种单基因、x连锁的神经系统疾病,导致女性神经发育迟缓,其特征是脊柱侧凸、癫痫发作、小头畸形、智力残疾、手部重复运动、睡眠受损、唾液过多、自主神经症状,通常很少或没有语言技能。据估计,在世界范围内,所有种族中每10- 1.5万名活产女性中就有1人患有RTT。甲基cpg结合蛋白2 (MECP2)位于染色体q28位置,包含4个外显子和5个蛋白结构域,是1999年[2]发现的RTT基因。该基因通过甲基cpg结合域(MBD)与胞嘧啶甲基化的核酸序列结合而被鉴定。随后,还鉴定出了核定位信号域(NLS)和转录抑制域(TRD)等功能域。MECP2蛋白参与染色质结构、异染色质重排、核组织等多种功能,调控剪接和DNA甲基化[4]。

Objective: Baseline sound level in a tertiary level NICU were measured and compared before and after educational intervention to evaluate the impact of a noise awareness educational program in decreasing the sound level in nursery.  Methods: The study was conducted in a tertiary level NICU. Participants were NICUdoctors, staff and parents of babies admitted in NICU. Participants were educatedregarding hazards of increased sound level in NICU and measures to reduce the sound level. Sound level in NICU was monitored using a sound meter at seven different time periods every day for 2 weeks. After 1 week of educational intervention period of NICU doctors, staff and parents, post intervention readings in similar format were checked again for 2 weeks. 1.3 Results: There was a significant reduction in sound levels (61.9+ 7.37dBA to 56.2+ 5.12dBA, p=0.002) at pre-intervention and post intervention period respectively. There was a significant difference in sound levels (p<0.01) within the groups at different time periods. 1.4 Conclusion: Noise in the NICU is more than the recommended sound levels of 45 dBA. Activity of people on floor is a significant contributor. Educational interventions of doctors, staff and parents can reduce sound levels significantly, and should be promoted in every NICU.
目的:对某三级新生儿重症监护病房的基线声级进行测量并比较教育干预前后的差异,评价噪声意识教育项目对降低托儿所声级的效果。方法:在某三级新生儿重症监护病房进行研究。参与者包括新生儿重症监护病房的医生、工作人员和新生儿的父母。对参与者进行了有关新生儿重症监护室中声级增加的危害和降低声级的措施的教育。采用声级计监测新生儿重症监护病房每天7个不同时段的声级,连续2周。NICU医生、工作人员及家长教育干预期1周后,再次检查干预后2周类似格式的读数。1.3结果:干预前和干预后的声级分别显著降低(61.9+ 7.37dBA至56.2+ 5.12dBA, p=0.002)。不同时段各组间声级差异有统计学意义(p<0.01)。1.4结论:新生儿重症监护病房的噪声超过了推荐的45 dBA声级。地板上的人的活动是一个重要的贡献者。医生、工作人员和家长的教育干预可以显著降低声级,应在每个新生儿重症监护室推广。

McKusick-Kaufman syndrome (MKKS) is a rare autosomal recessive disorder. We report the case of McKusick-Kaufman syndrome in a term female neonate. Antenatal ultrasound found a large cystic abdominal mass corresponding to hydrometrocolpos with bilateral hydronephrosis. This finding was confirmed after birth and its association to polydactyly permitted us to give the diagnosis of MKKS. Exploratory laparotomy revealed vaginal atresia and suspected the association to Hirschprung disease. MKKS is difficult to diagnose antenatally and complementary explorations should be done after birth to establish a definitive diagnosis.
McKusick-Kaufman综合征(MKKS)是一种罕见的常染色体隐性遗传病。我们报告的情况下,McKusick-Kaufman综合征在一个足月的女性新生儿。产前超声发现腹部大囊性肿块,与双侧肾积水相对应。这一发现在出生后得到证实,其与多指畸形的关联使我们能够给出MKKS的诊断。剖腹探查发现阴道闭锁,怀疑与Hirschprung病有关。MKKS在产前很难诊断,应在出生后进行补充检查以确定诊断。

The combined prevalence of partial or complete agenesis of the corpus callosum (ACC) is estimated at 0.02-0.5%.This common brain malformation mainly due to a prenatal abnormality commissuration. We report a case of diagnosis of isolated fetal CCA. Magnetic resonance imaging appears to be an important adjunct as it allows direct visualization. The prognosis in isolated agencies of the corpus callosum remains uncertain.
胼胝体部分或完全缺失(ACC)的综合患病率估计为0.02-0.5%。这种常见的脑畸形主要是由于产前畸形合拢所致。我们报告一例孤立性胎儿CCA的诊断。磁共振成像似乎是一个重要的辅助手段,因为它允许直接可视化。胼胝体孤立分支的预后仍不确定。
