Despite of their rarity, TTAFs can significantly impact the lives of young individuals involved in sports and other strenuous activities. The mechanism of TTAFs occurrence involves forceful quadriceps contraction against resistance or rapid knee flexion with contracted quadriceps. TTAFs may coincide with other related injuries due to their mechanism of occurrence and commonly present with an abrupt onset of pain, focal soft-tissue swelling and tenderness on palpation. Predisposing factors such as a history of Osgood-Schlatter disease and an extreme body mass index (BMI) could contribute to TTAFs susceptibility. Diagnosis of TTAFs typically relies on X-rays, complemented by computed tomography (CT) and magnetic resonance imaging (MRI) for screening associated injuries and preoperative assessment. While a well-established classification system exists, with the Ogden classification being the most commonly employed, intriguingly, a direct correlation between fracture type and treatment method, as well as the choice of surgical fixation modality, remains elusive. The management of TTAFs encompasses both conservative and surgical approaches, with open reduction internal fixation (ORIF) being the predominant surgical method and the prognosis for this condition is generally favorable. By synthesizing existing knowledge and presenting potential areas of uncertainty, this review aims to offer valuable insights to orthopedic practitioners when they are confronted with this infrequent injury.","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"3 1","pages":"e2521"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12118110/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyzing injury types in suspected CPA cases before and during the pandemic can provide valuable insights. The objective of this study is to compare the incidences and types of injuries detected by skeletal surveys in suspected CPA cases at a large academic children's hospital before and during the COVID-19 pandemic. The study compared the incidences and proportion of specific injury sites, types of traumas, and demographic characteristics before and during the pandemic using Pearson's chi-squared and Fisher's exact tests. A total of 479 patients who underwent skeletal surveys were included, with 306 patients sampled before the pandemic (63.8%) and 173 patients sampled during the pandemic (36.1%). There were no significant differences in age, gender, or ethnicity between the two groups. Highly suspicious CPA incidences were similar before (0.87/month) and during (0.81/month) the pandemic, reflecting 10.5% and 11.6% of all patients who underwent skeletal surveys, respectively. There were no significant demographic differences between the groups. However, the proportion of patients with intracranial or retinal hemorrhage significantly decreased (p < 0.05) during the pandemic, with no significant differences in types of skeletal fractures. In conclusion, the overall incidence of CPA remained similar before and during the pandemic. The significant decrease in intracranial and retinal hemorrhages suggests a potential change in injury patterns or reporting. Further research is needed to understand the factors contributing to these findings.Clinical trial registration: This study is a retrospective clinical trial and therefore not subject to clinical trial registration requirements.","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"3 1","pages":"e2526"},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12118100/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Managing the neonatal airway requires faculties in mask ventilation. Many trainees, however, have limited clinical experience with this skill. An algorithmic method incorporating the steps an airway expert would use for neonatal mask ventilation was designed. The goal of teaching this system, the \"Five Breath Method,\" is to assist trainees with learning and incorporating the steps of neonatal mask ventilation into clinical practice. We hypothesized that for pediatric residents, participating in a teaching session on the Five Breath Method would significantly decrease the time to achieve ventilation (\"air entry\") in a resuscitation scenario. A pilot study was completed on the Five Breath Method with 23 pediatric residents as subjects. Training in the Five Breath Method reduced the time required to achieve air entry using a neonatal simulator. Subjects required 57 [29-149 and 13-180] seconds (median [interquartile range and minimum-maximum]) before the teaching session and 16 [10-35 and 8-60] seconds after learning the Five Breath Method; Z = -4.11, and P < 0.001. For the 14 of the original subjects who were able to participate in the follow-up study 2-5 months later, 24 [22-38 and 12-69] seconds (median [interquartile range and minimum-maximum]) were required to achieve air entry in the identical experimental scenario. This showed an improvement in time to air entry when compared to that before training; Z = -2.42, and P = 0.01552. This study showed that as little as 10 min of training could drastically improve skills. Learning the Five Breath Method also led to retention of skills over time.","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"3 3","pages":"e2520"},"PeriodicalIF":0.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12483298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though spina bifida is divided into several subtypes, myelomeningocele-the most severe form of spina bifida often associated with a markedly diminished quality of life-accounts for a significant portion of cases. A broad range of genetic and environmental factors, many of which are still unknown, influence spina bifida, making it difficult to provide a comprehensive etiology for the disorder. Folic acid supplementation aided by the mandatory fortification of food is preventive; still, spina bifida persists due to numerous other confounding factors that affect risk. This article reviews the latest studies pertaining to the risk factors and genetics involved in spina bifida in an attempt to elucidate the complex background of the congenital malformation. Additionally, this review highlights the significant impact of environmental pollutants, adverse medication effects, and maternal health conditions such as diabetes and obesity on the prevalence of spina bifida. Emerging research on gene-environment interactions provides insight into how specific genetic variants may influence susceptibility to these environmental factors. We also discuss new technologies in genetic sequencing that show promise for the large-scale discovery of genes associated with spina bifida risk. Understanding these intricate interactions is crucial for developing effective prevention and intervention strategies.","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"3 2","pages":"e2517"},"PeriodicalIF":0.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12258106/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that a total of 77 pathogen-positive patients were detected in the 171 patients (culture-positive rate of 45.0%), 15 categories of pathogenic bacteria, and the highest detection rates were 52 cases of Staphylococcus aureus (67.5%), Streptococcus pyogenes in 7 cases (9.1%), and Streptococcus pneumoniae in 5 cases (6.5%). Comparison of these three pathogens revealed that the age of the Staphylococcus aureus and Streptococcus pyogenes groups was significantly older than that of the Streptococcus pneumoniae group (p < 0.05), and that the white blood cell count (WBC) of the Streptococcus pyogenes group was significantly higher than that of the Staphylococcus aureus group (p < 0.05), and that the Streptococcus pyogenes group had a significantly higher procalcitonin (PCT), which was significantly higher in the Streptococcus pneumoniae group (p < 0.05). The results suggest that the pathogenic bacteria of septic arthritis in children are mainly Staphylococcus aureus, Streptococcus pneumoniae infection occurred more commonly in the infant stage, and Staphylococcus aureus and Streptococcus pyogenes were detected frequently in school-age children.

It is very important to study the etiology and pathogenesis of asthma for clinical asthma prevention and treatment. In this study, to understand the correlation between C-X-C motif chemokine ligand 14 (CXCL14) in bone marrow dendritic cells (BMDCs) and antigen presentation of asthma dendritic cells (DCs), an in vitro model of BMDCs was constructed for RNA sequencing (RNA-seq). The changes of CXCL14 in BMDCs after house dust mites (HDM) stimulation were evaluated. Finally, evaluated the inflammation of the lung tissue in mice, and the expression of costimulatory molecules on the DCs surface in the lung tissue was analyzed by flow cytometry. The results showed that CXCL14 was upregulated in BMDCs after HDM stimulation, and its function was related to signal molecule interaction and the immune system. The expression of CXCL14 was increased in the HDM-induced allergic asthma model. Knockdown of CXCL14 reduced the expression of costimulatory molecules CD86, CD80, and major histocompatibility complex II on the surface of DCs in the lung tissue of mice, induced immune tolerance, and reduced lung inflammatory cell infiltration and inflammatory factor levels, providing new ideas and theoretical basis for the clinical treatment of bronchial asthma.","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"3 3","pages":"e2514"},"PeriodicalIF":0.0,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12483293/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
