BackgroundTherapeutic plasma exchange (TPE) is an extracorporeal treatment that can be used in adult and pediatric patients with acute demyelinating syndromes of the central nervous system. In this study, the efficacy and safety of TPE was evaluated in 10 pediatric patients who underwent TPE that were unresponsive to corticosteroid treatment.MethodsRecords of 10 pediatric patients who underwent TPE in our pediatric intensive care unit (PICU) between May 2017 and June 2020 were used. Expanded Disability Status Scale (EDSS), Gait Scale (GS), and Visual Outcome Scale (VOS) were applied to the patients before and after TPE.ResultsOf the 10 patients who underwent TPE, five were diagnosed with multiple sclerosis (MS), three with transverse myelitis (TM), and two with acute disseminated encephalomyelitis (ADEM). The median age of the patients was 13.3 years (IQR 8-15), and the median day from symptom onset to onset of TPE was 12.5 days (IQR 7-28). A total of 104 TPE sessions were performed successfully. While no complications were encountered in three patients during the sessions, the most common complication was hypofibrinogenemia. The decrease in EDSS and GS scores was found to be consistent with the clinical response of the patients. There was no statistically significant decrease in the VOS.ConclusionsWith this study, we can say that TPE is a feasible, effective, and safe treatment modality in children with acute demyelinating syndromes of the central nervous system. 相似文献

Although births below 28 completed weeks' of gestation contribute to less than 1% of all preterm births globally, the impact of extreme prematurity (EPT) on neurodevelopmental outcomes across the life-course is disproportionately large. Higher rates and increased severity of neurodevelopmental impairments (NDIs) are reported among extremely preterm infants (EPIs). Cognitive skills, motor skills (manifesting as cerebral palsy) and vision are most commonly affected, with effects pervasive throughout school, adolescence and early adulthood. In addition, poorer academic outcomes and higher rates of psychiatric morbidity are seen among EPTs. Consistent improvements in EPI survival in recent years has not been matched with improvements in neurodevelopmental outcomes, especially for those born at less than 25 gestational weeks. However, over the last 20 years, several national and cross-national cohort studies have helped advance our understanding of extreme prematurity's developmental and life-course consequences. Here we provide an overview of the key findings from 13 multi-centre cohorts measuring neurodevelopmental outcomes and discuss the theoretical and epidemiological perspectives of NDIs in the context of extreme prematurity to guide communication with families and shared care decision-making. 相似文献

While children in general are usually seen as a societal priority, many children are disadvantaged by marginalization, with adverse effects on health and development. Following feasibility studies, the European Commission has now adopted a formal Child Guarantee of service access. This paper links the Feasibility Studies to other reports on the need to address marginalized and institutionalized children. The problems in identifying and quantifying such children are outlined, as are the challenges of planning for these groups of children and the difficulty of finding universal definitions and data. This European Union initiative is timely, given that around a quarter of European children are marginalized, while the effects of Covid-19 will add to this marginalization. 相似文献

One in five children in the UK are affected by domestic violence and abuse. However, primary care clinicians (GPs and nurses) struggle to effectively identify and support children and young people living in homes where it is present. The IRIS+ (Enhanced Identification and Referral to Improve Safety) training and advocacy support intervention aimed to improve how clinicians respond to children and young people affected by domestic violence and abuse. IRIS+ training was delivered as part of a feasibility study to four general practices in an urban area in England (UK). Our mixed method design included interviews and questionnaires about the IRIS+ intervention with general practice patients, including children and young people as well as with clinicians and advocacy service providers. We collected the number of identifications and referrals by clinicians of children experiencing domestic violence and abuse through a retrospective search of medical and agency records 10 months after the intervention. Forty-nine children exposed to domestic violence and abuse were recorded in medical records. Thirty-five children were referred to a specialist domestic violence and abuse support service over a period of 10 months. Of these, 22 received direct or indirect support. The qualitative findings indicated that children benefitted from being referred by clinicians to the service. However, several barriers at the patient and professional level prevented children and young people from being identified and supported. Some of these barriers can be addressed through modifications to professional training and guidance, but others require systematic and structural changes to the way health and social care services work with children affected by domestic violence and abuse. 相似文献

阐述了孙丽平教授治疗小儿咳嗽临床常用的8组对药,即前胡与白前、紫菀与款冬花、苦杏仁与桃仁、橘红与桔梗、瓜蒌与冬瓜子、地龙与僵蚕、川贝母与浙贝母、沙参与麦冬的配伍特点及临床应用心得,并列举其临证经典医案,结合中药学理论和现代药理学研究,总结分析孙教授运用对药治疗小儿咳嗽的学术经验及用药思路。孙教授认为小儿体属稚阳,其咳多起肺虚实之热,主以清热护肺,次以运脾滋阴,主次同疗,则阴阳平矣,强调小儿咳嗽用药,应以辨别个体体质差异为基础,提倡对药组方"肺脾同治、气血通调、阴阳平补"的用药理念。附案例1则,以资验证。 相似文献
