概括

儿科脊髓疾病 (SCD) 影响骨和肌肉发育. 与举重的同龄人相比,不举重的儿童的骨密度和肌肉强度明显较低.

科学领域:

儿科整形外科儿科整形外科
神经学神经学
骨健康研究骨健康研究

背景情况:

儿童脊髓疾病 (SCD) 很少见,但可能导致严重的肌肉骨并发症.
人们对骨健康及其在儿科SCD患者的发展的了解有限,特别是在澳大利亚.

研究的目的:

研究和描述被诊断患有脊髓疾病的儿童的骨和肌肉发育.
评估承重状态对儿科SCD肌肉骨结局的影响.

主要方法:

在墨尔本皇家儿童医院 (The Royal Children's Hospital,Melbourne) 进行了一项涉及十名患有SCD的儿科参与者的横截面研究.
用外围定量计算断层扫描 (pQCT) 扫描来评估骨健康.
进行了血液检查,以分析骨健康的生物化学.

主要成果:

与举重的儿童相比,非举重的儿童表现出明显较低的小腿椎骨密度 (Z-score -6.5 vs. -2.4) 和肌肉横截面积 (Z-score -4.7 vs. -1.1).
在所有参与者的半径中观察到骨面积和强度的减少.
在一些参与者身上发现了性酸酶,酸盐和25-氧维生素D水平的异常.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
