Patterns of Fever01:26

Patterns of Fever

3.0K
Before understanding the types and patterns of fever, it is essential to know its phases.

Types of Fever01:25

Types of Fever

539
Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

Increased Body Temperature01:25

Increased Body Temperature

1.7K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Bacterial Phylum Spirochaetes01:30

Bacterial Phylum Spirochaetes

110
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

438
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

410
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

科学领域:

  • 传染性疾病
  • 微生物学
  • 公共卫生

背景情况:

  • 肠道热,包括伤寒和偏伤寒,是由Salmonella enterica Typhi和Paratyphi引起的.
  • 这些感染在缺乏水,卫生和卫生设施 (WASH) 的地区普遍存在.
  • 便口传播促进了这些衰弱性疾病的传播.

研究的目的:

  • 提供肠热的全面概述,包括其病因,传播,临床表现,诊断,治疗和预防.
  • 突出区分肠热与其他发烧性疾病的挑战.
  • 强调抗菌素耐药性模式和疫苗接种在疾病管理中的重要性.

主要方法:

  • 对诊断方法的文献审查,包括血液和骨髓培养.
  • 分析推的治疗方案,如阿兹胺,西普罗素和塞夫特里亚.
  • 评估现有的预防策略,包括伤寒V-结合剂疫苗和WASH改进.

主要成果:

  • 肠热的典型症状包括逐渐升高的发烧,不适,头痛和肌痛,这些症状往往因抗菌药物耐药性而复杂化.
  • 血液或骨髓培养是参考诊断,尽管血液培养的敏感性有限.
  • 需要根据局部模式仔细选择治疗.

结论:
