概括

基本血小板血 (ET) 在儿童中很少见. 本案例研究详细介绍了一名被诊断患有ET的14岁儿童,强调了诊断挑战和成功的氧尿素治疗,以控制高血小板数量和症状.

科学领域:

儿科血液学儿科血液学
在瘤学瘤学.
分子诊断学分子诊断

背景情况:

血栓细胞瘤在儿童中很常见,通常是炎症或铁缺乏的次要原因.
基本血小板血 (ET) 是一种骨髓增殖性新生体,在儿科患者中异常罕见.
儿科ET可以导致血栓/出血事件,并可能导致骨髓纤维化或白血病的进展.

研究的目的:

报告一个罕见的儿科必需血小板血 (ET) 病例.
为了说明儿童ET的诊断复杂性和管理策略.
强调需要专门针对儿科的指导方针和研究.

主要方法:

一个14岁的女性病例报告出现了反复复发的形,红血,疼痛,麻醉和头痛的症状.
排除了血栓细胞瘤和雷诺现象的二次原因.
诊断工作包括骨髓活检,腹部超声波和JAK2 V617F突变分析.

主要成果:

确诊了JAK2 V617F突变和持久性血栓细胞瘤 (> 1,092 × 109/L) 的基本血栓细胞血症 (ET).
最初用乙撒利酸治疗显示部分改善;基尿素导致显著的血小板减少和临床益处.
患者在三年随访期间保持稳定,没有不良反应或白血病转变.

结论:

儿科ET很少见,在诊断上具有挑战性,并且需要排除反应性原因,骨髓和分子评估.
由于缺乏儿科专用指导方针,管理是复杂的,通常依赖于成人协议.
细胞还原疗法和长期随访至关重要;基于证据的儿科策略需要多中心研究.

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Aip1p Dynamics Are Altered by the R256H Mutation in Actin

Disease-causing mutations in actin can alter cytoskeletal function. Cytoskeletal dynamics are quantified through imaging of fluorescently tagged proteins using total internal fluorescence microscopy. As an example, the cytoskeletal protein, Aip1p, has altered localization and movement in cells expressing the mutant actin isoform,...
