概括
溶血性尿性综合征 (HUS) 和血栓性血栓细胞衰竭紫外线 (TTP) 是一种罕见的疾病,其特征是血栓性微血管病变 (TMA). 本综述阐明了Siga毒素-HUS,非典型HUS和TTP之间的区别,有助于儿童和成人的诊断和管理.
科学领域:
- 血液学 血液学 血液学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 遗传学 遗传学 是一个
背景情况:
- 溶血性尿性综合征 (HUS) 和血栓性血栓细胞衰竭紫外线 (TTP) 是一种罕见的疾病,呈现为血栓性微血管病变 (TMA).
- TMA涉及微血管血栓形成,导致血小板数量低,血液溶解性贫血和器官功能障碍.
- 从历史上看,区分HUS和TTP依赖于临床表现,这些表现往往重叠.
研究的目的:
- 为了审查TMA综合征的分子分类:滋賀毒素产生大肠杆菌HUS (STEC-HUS),非典型的HUS (aHUS/CM-TMA) 和TTP.
- 划分TMA在儿科和成年人群中的不同病因和临床表现.
- 通过强调与患者年龄相关的关键特征和差异来指导诊断和管理.
主要方法:
- 文献审查侧重于STEC-HUS,aHUS/CM-TMA和TTP.
- 分析病原机制,临床表现,诊断标准和管理策略.
- 疾病特征和患病率在儿科和成人患者中的比较.
主要成果:
- 现在,TMA综合征的分类基于潜在的机制:STEC-HUS,aHUS/CM-TMA (补充失调) 和TTP (ADAMTS13缺乏).
- 儿科TMA主要是STEC-HUS,其他原因是aHUS/CM-TMA和肺炎球菌HUS;像先天性TTP这样的罕见疾病在婴儿中发生.
- 成人TMA更频繁地涉及次要原因和获得的ADAMTS13缺乏症,导致由于更广泛的差异诊断导致诊断延迟.
结论:
- 分子分类已经完善了对TMA综合征的理解和分化.
- 特定于年龄的病因和表现需要针对HUS和TTP量身定制的诊断和管理方法.
- 了解这些区别对于及时有效的患者护理至关重要,特别是在成年人中,诊断可能更复杂.

Levels of Health Promotion and Illness Prevention
12.7K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.

Models of Health Promotion and Illness Prevention II
1.6K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

Continuing Care
1.5K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Classification of Illness
7.5K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...
