病毒物种在急诊室显著影响儿科喘恶化. 甲状腺病毒感染与较轻的病例有关,而肠道病毒D68则导致更严重的喘发作.
科学领域:
- 儿科急救医学 儿科急救医学
- 传染性疾病 传染性疾病
- 呼吸系统医学 呼吸系统医学
背景情况:
- 呼吸系统病毒通常会在儿童中引发喘恶化.
- 病毒感染特征对儿科喘呈现和急诊室治疗反应的具体影响尚不清楚.
研究的目的:
- 为了调查患有急诊室喘恶化儿童的病毒感染特征.
- 确定病毒因素,恶化的严重程度和治疗结果之间的关联.
主要方法:
- 对107名儿童 (4-18岁) 的前性研究,这些儿童因喘恶化而接受治疗.
- 鼻子抽样的病毒元基因组分析,以确定病毒存在,载量和物种.
- 使用小儿喘严重程度 (PAS) 评分,临床印象和生命体征来评估恶化严重程度;治疗反应定义为没有额外治疗的出院.
主要成果:
- 86%的分析样本 (73名儿童) 检测到病毒,其中犀牛病毒A (RV-A),RV-C和肠道病毒D68是最常见的.
- RV-A与较轻的恶化 (OR=0.25) 和更好的治疗反应相关.
- 肠道病毒D68与更严重的恶化相关 (OR=8.3),没有显著的治疗反应相关性. 病毒载量与表明严重程度的生命体征相关.
结论:
- 病毒物种显著影响儿科喘恶化严重程度和治疗反应.
- 早期的病原体识别可以指导急诊室的治疗策略.
- 需要进一步的研究,以了解病毒特异性恶化的病理生物学,并优化治疗.

Asthma-I: Introduction
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
