Background

Children are vulnerable to Human Cytomegalovirus (HCMV) infection, the majority of infections of which are asymptomatic, which often leads to missed diagnoses. Missing early diagnosis and treatment may have adverse consequences for the child. Therefore, the purpose of this study was to evaluate the hematological parameters and clinical symptoms in HCMV-infected infants and children under 6 years old.

Method

This study conducted a retrospective analysis of laboratory data from 223 children aged 0 day to 6 years who had undergone urine HCMV-DNA test at the Luohu People's Hospital. We categorized children into two groups based on the results of their urine HCMV-DNA test: the HCMV infected group and the HCMV non-infected group. Furthermore, we divided them into different age groups: 0–21 days, 22 days–<6 months, 6 months–<1 year, 1–<2 years, and 2–6 years.

Results

The lymphocyte percentage (L%) and lymphocyte count (LYM) of HCMV-infected children aged 0–6y were significantly higher than those of the control group (P < 0.05). The alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT) of HCMV-infected children aged 0–<1y and aspartate aminotransferase (AST) of HCMV-infected children aged 0d–<2y were significantly higher than those of the control group (P < 0.05), but this difference was not evident among older children. We found that GGT was highest in HCMV-infected children aged 0–21d and decreased with the increase of age. Furthermore, our data indicate that older children exhibit a reduced diversity of illnesses after infection.

Conclusion

We conclude that HCMV infection can increase lymphocytes in the peripheral blood of children aged from 0 to 6 years and can cause more severe hepatobiliary injury in younger children.

背景：儿童易受人类巨细胞病毒（HCMV）感染，大多数感染无症状，这往往导致漏诊。错过早期诊断和治疗可能对儿童造成不良后果。因此，本研究的目的是评估hcmv感染的婴儿和6岁以下儿童的血液学参数和临床症状。方法：回顾性分析罗湖市人民医院223例0 ~ 6岁儿童尿液HCMV-DNA检测的实验室资料。我们根据尿液HCMV- dna检测结果将儿童分为两组：HCMV感染组和HCMV未感染组。结果：0 ~ 6岁HCMV感染患儿外周血淋巴细胞百分率（L%）和淋巴细胞计数（LYM）均显著高于对照组(P)。结论：HCMV感染可使0 ~ 6岁患儿外周血淋巴细胞升高，低龄患儿肝胆损伤更严重。

Objective

Early prognostication in infants with neonatal hypoxic-ischemic encephalopathy (HIE) is crucial for follow-up management. Alternations of microstructural integrity of neural fiber tracts in large-scale neural networks might predict neurological outcomes.

Methods

All consecutively-admitted patients with neonatal HIE from 2016 to 2020 were enrolled. Diffusion tensor imaging (DTI) tractography was performed at 4–7 days of age. Neurodevelopmental outcomes at 24 months of age were assessed with Bayley Scales of Infant Development, 3rd edition.

Results

A total of 62 HIE infants were enrolled, and 53 of these underwent DTI. Fractional anisotropy (FA) and mean diffusivity (MD) were measured to indicate the microstructural integrity of tracts, including the arcuate fasciculus, uncinate fasciculus, inferior fronto-occipital fasciculus, corticospinal tract (CST), and optic radiations (OR). Lower FA values of target tracts were associated with lower developmental scores at 24 months of age, particularly in the CST and OR (all P ≤ 0.003). The prognostic accuracy of FA values in CST surpassed that in the region of thalamus/basal ganglia (area under curves 0.839, 95 % CI: 0.728–0.950 vs. 0.755, 95 % CI: 0.583–0.928). Furthermore, the correlation between FA values in target tracts and developmental scores was most significant in infants with HIE stage III and this was not affected by therapeutic hypothermia.

Conclusion

Tract integrity in the CST and OR detected by DTI provides valuable insights for early prognostication in infants with HIE, regardless of therapeutic hypothermia.

目的：新生儿缺氧缺血性脑病（HIE）的早期预后对后续治疗至关重要。大规模神经网络中神经纤维束微观结构完整性的改变可能预测神经预后。方法：选取2016 ~ 2020年所有连续入院的新生儿HIE患者。4-7日龄进行弥散张量成像（DTI）示束造影。使用Bayley婴儿发育量表（第三版）评估24月龄时的神经发育结果。结果：共纳入62例HIE患儿，其中53例接受了DTI治疗。测量分数各向异性（FA）和平均扩散率（MD）来指示束的微观结构完整性，包括弓状束、钩状束、额枕下束、皮质脊髓束（CST）和视光辐射（OR）。靶束FA值较低与24月龄时发育评分较低相关，尤其是CST和OR（均P≤0.003）。FA值对CST的预后准确性优于丘脑/基底节区（曲线下面积0.839,95% CI: 0.728-0.950 vs. 0.755, 95% CI: 0.583-0.928）。此外，靶束FA值与发育评分之间的相关性在HIE III期婴儿中最为显著，并且不受治疗性低温的影响。结论：DTI检测CST和OR的气道完整性为HIE婴儿的早期预后提供了有价值的见解，无论治疗性低温如何。

Elevated blood pressure (BP) and hypertension are common in children and adolescents, significantly increasing the risk of cardiovascular disease (CVD) in adulthood. Accurately assessing the prevalence and significance of pediatric hypertension requires a clear definition. The use of age-, sex-, and height-dependent percentiles to define pediatric hypertension began in 1977. Since then, several national and international clinical practice guidelines have refined its classification, diagnosis, and management, with notable contributions from The Fourth Report in 2004, the European Society of Hypertension (ESH) in 2016, and the American Academy of Pediatrics (AAP) in 2017. The 2017 AAP guideline redefined pediatric hypertension, increasing the number of children classified with elevated BP or hypertension. Despite these advancements, a universal diagnostic criterion for pediatric hypertension is still lacking. This review aims to summarize recent research on pediatric hypertension, focusing on evolving definitions, persistent knowledge gaps, and future directions. Addressing pediatric hypertension early with a lifespan approach is essential to reducing the global prevalence of hypertension and its associated CVD burden. The need for continued study and innovative strategies is underscored by research gaps in the prevention, detection, classification, and treatment of pediatric hypertension.

血压升高（BP）和高血压在儿童和青少年中很常见，显著增加了成年后心血管疾病（CVD）的风险。准确评估儿童高血压的患病率和意义需要明确的定义。1977年开始使用年龄、性别和身高依赖百分位数来定义小儿高血压。从那时起，一些国家和国际临床实践指南已经完善了其分类，诊断和管理，其中包括2004年的第四次报告，2016年的欧洲高血压学会（ESH）和2017年的美国儿科学会（AAP）。2017年AAP指南重新定义了儿童高血压，增加了血压升高或高血压的儿童数量。尽管取得了这些进展，但儿童高血压的普遍诊断标准仍然缺乏。本文综述了儿童高血压的最新研究，重点介绍了不断发展的定义、持续存在的知识差距和未来的发展方向。采用生命周期方法早期处理儿童高血压对于降低高血压的全球患病率及其相关的心血管疾病负担至关重要。在儿童高血压的预防、检测、分类和治疗方面的研究差距强调了继续研究和创新策略的必要性。

Background

Mixed receptive-expressive language disorder (MLD) may have long-term impacts on development, sociobehavioral problems, and mental health issues in children. Speech and language therapy (SLT) has been proven to improve developmental language disorder (DLD) in childhood, and post-SLT improvements in language development are more prominent in younger children with DLD than in older children. However, there is still limited evidence on MLD. Therefore, this study aimed to investigate whether post-SLT improvements occur in children with MLD and whether there are age-related differences in improvements.

Materials and methods

A retrospective study was conducted to achieve this aim. We examined medical records from September 2020 to May 2023 and collected information on children who received SLT for DLD. Children who were diagnosed with MLD by the Comprehensive Development Inventory for Infants and Toddlers (CDIIT) and underwent post-SLT reassessment by the CDIIT were included for analysis. All subjects were furthermore categorized into 2 groups based on their age at initial assessment: ≤3 years and >3 years. The pre- and post-intervention CDIIT scores were compared.

Results

A total of 41 children with MLD were included. The main effect of assessment time showed significant improvements in all language domain after SLT (all p < 0.01, η² > 0.14). While the main effect of age group revealed that post-SLT improvement was not influenced by age group classification, indicating comparable post-SLT improvements between the two age groups (all p > 0.05). Furthermore, the comparison of pre- and post-intervention differences between the two age groups did not yield significant differences, indicating that 12-week SLT was beneficial for children with MLD in both age groups.

Conclusion

The present study indicated that post-SLT improvement occurred in all language domains among children with MLD. Furthermore, comparable improvement was observed between the two age groups, indicating that SLT is beneficial for children with MLD across different age ranges.

背景：混合性接受-表达语言障碍（MLD）可能对儿童的发育、社会行为问题和心理健康问题产生长期影响。言语和语言治疗（SLT）已被证明可以改善儿童时期的发展性语言障碍（DLD），并且SLT后的语言发展改善在年幼的DLD儿童中比在年龄较大的儿童中更为突出。然而，关于MLD的证据仍然有限。因此，本研究旨在探讨slt后的改善是否发生在MLD儿童身上，以及这种改善是否存在与年龄相关的差异。材料和方法：为达到此目的进行回顾性研究。我们检查了2020年9月至2023年5月的医疗记录，并收集了接受SLT治疗DLD的儿童的信息。通过婴幼儿综合发展量表（CDIIT）诊断为MLD的儿童，并通过CDIIT进行slt后再评估，纳入分析。所有受试者根据初测年龄分为≤3岁和≤3岁两组。比较干预前和干预后的CDIIT评分。结果：共纳入41例MLD患儿。评估时间的主效应在语言学习后各语言领域均有显著改善（p < 0.05）。而年龄组的主要效应显示，slt后的改善不受年龄组分类的影响，表明两个年龄组之间的slt后改善具有可比性（均p < 0.05）。此外，两个年龄组的干预前后差异比较没有产生显著差异，表明12周的SLT对两个年龄组的MLD儿童都是有益的。结论：本研究表明，轻度语言障碍儿童的所有语言领域都出现了slt后的改善。此外，在两个年龄组之间观察到可比性的改善，表明SLT对不同年龄范围的MLD儿童有益。

Background

Wilms tumor (WT) is the most common renal malignancy in children. With current treatments, the 5-year overall survival (OS) rate for children with WT is approximately 90 %. However, nearly 15 % of patients experience disease recurrence. A rare but severe treatment-related complication is hepatopathy-thrombocytopenia syndrome (HTS). In this study, we evaluated the characteristics, treatment outcomes, and complications of patients with WT, particularly focusing on HTS and relapse cases.

Methods

We conducted a retrospective observational study of WT cases from 2001 to 2021 at a tertiary care hospital in central Taiwan. Patient records were examined to collect information on age at diagnosis, sex, disease stage, treatment, tumor characteristics, treatment complications, and outcomes.

Results

We included 23 pediatric patients with untreated WT. Their median follow-up duration was 102 months. Their median age was 3.4 (0.8–10.8) years. The most common tumor stage was Stage II (9/23, 39.1 %), followed by Stage I (7/23, 30.4 %), III (5/23, 21.7 %), IV (1/23, 4.3 %), and V (1/23, 4.3 %). One patient with Stage IV disease had distant metastasis of the right atrium. Two patients with Stage III disease developed HTS during treatment. Relapse occurred in 3 (13 %) of 23 patients, and the average time to relapse from the initial diagnosis was 25 (range, 9–44) months. All patients survived during the follow-up period, but one continued to experience refractory lung recurrence. Two patients underwent hematopoietic stem cell transplantation for relapse/refractory disease. No disease-related mortality was noted. The 5-year event-free survival and OS rates were 86.2 % and 100 %, respectively.

Conclusion

Although WT generally has a favorable prognosis, physicians should remain mindful of potential treatment-associated complications and the risk of relapse when managing WT in children.

背景：肾母细胞瘤（Wilms tumor， WT）是儿童最常见的肾脏恶性肿瘤。在目前的治疗下，WT患儿的5年总生存率（OS）约为90%。然而，近15%的患者经历疾病复发。一种罕见但严重的治疗相关并发症是肝病-血小板减少综合征（HTS）。在这项研究中，我们评估了WT患者的特征、治疗结果和并发症，特别关注了HTS和复发病例。方法：我们对台湾中部一家三级医院2001年至2021年的WT病例进行回顾性观察研究。检查患者记录以收集诊断时的年龄、性别、疾病分期、治疗、肿瘤特征、治疗并发症和结局等信息。结果：我们纳入了23例未经治疗的WT患儿，他们的中位随访时间为102个月。中位年龄为3.4（0.8-10.8）岁。最常见的肿瘤分期为II期（9/ 23,39.1%），其次为I期（7/ 23,30.4%）、III期（5/ 23,21.7%）、IV期（1/ 23,4.3%）和V期（1/ 23,4.3%）。1例IV期患者右心房有远处转移。两名III期患者在治疗期间出现HTS。23例患者中有3例（13%）复发，从初次诊断到复发的平均时间为25个月（范围9-44个月）。所有患者在随访期间均存活，但有1例持续出现难治性肺复发。2例患者因复发/难治性疾病接受了造血干细胞移植。未发现与疾病相关的死亡率。5年无事件生存率和总生存率分别为86.2%和100%。结论：虽然WT通常具有良好的预后，但医生在处理儿童WT时应注意潜在的治疗相关并发症和复发风险。

Background

Urinary tract infections (UTI) are the leading cause of severe bacterial infection in children under 24 months. Increasing antimicrobial resistance, particularly to third-generation cephalosporins, is a growing concern. This study examines recent resistance trends in young children with UTI in Korea.

Methods

A retrospective study was conducted on children under 24 months who presented with UTI to three university hospitals in Korea between 2010 and 2023. Children diagnosed with UTI and/or acute pyelonephritis with gram-negative bacteria identified in urine cultures were included. Antibiotic susceptibility data of antibiotics commonly used to treat pediatric UTI were collected, focusing on third-generation cephalosporins. Trends in resistance were analyzed according to age group, causative organism, and the presence of congenital anomalies of the kidney and urinary tract.

Results

A total of 10,029 children were included, with a mean age of 4.0 months (IQR, 2.3–6.6 months); 67.9 % were male, and Escherichia coli accounted for 84 % of isolates. Resistance to cefotaxime increased significantly from around 10 % in the early 2010s to over 30 % after 2020. This increasing trend was consistent regardless of age group, causative organism, or presence of congenital anomalies of the kidney and urinary tract, although it showed a decreasing trend after 2021.

Conclusions

There has been a significant rise in resistance to third-generation cephalosporins among young children with UTI in Korea over the past decade. These findings suggest a need to reconsider the empirical use of these antibiotics and consider alternative treatments to effectively manage UTI and prevent kidney scarring in Korean children.

背景：尿路感染（UTI）是24个月以下儿童严重细菌感染的主要原因。日益增加的抗菌素耐药性，特别是对第三代头孢菌素的耐药性日益引起关注。本研究调查了韩国尿路感染幼儿近期的耐药性趋势。方法：对2010年至2023年间在韩国三所大学医院就诊的24个月以下尿路感染患儿进行回顾性研究。被诊断为尿路感染和/或急性肾盂肾炎的儿童在尿培养中发现革兰氏阴性细菌。收集儿童尿路感染常用抗生素的药敏数据，重点收集第三代头孢菌素类药物。根据年龄、病原菌、有无肾、尿路先天性异常等因素分析耐药趋势。结果：共纳入患儿10029例，平均年龄4.0个月（IQR, 2.3 ~ 6.6个月）；男性占67.9%，大肠杆菌占84%。对头孢噻肟的耐药性显著增加，从2010年代初的10%左右增加到2020年后的30%以上。尽管在2021年之后呈下降趋势，但无论年龄组、致病生物或是否存在肾脏和泌尿道先天性异常，这种增长趋势都是一致的。结论：在过去十年中，韩国尿路感染幼儿对第三代头孢菌素的耐药性显著上升。这些发现表明，需要重新考虑这些抗生素的经验性使用，并考虑替代治疗，以有效地管理尿路感染和预防韩国儿童肾脏瘢痕形成。
