Patterns of Fever01:26

Patterns of Fever

Before understanding the types and patterns of fever, it is essential to know its phases.
Types of Fever01:25

Types of Fever

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

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 response to an infection or illness.
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Methods of reducing fever01:22

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
Pharmacological Methods of Reducing Fever:
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...

Summary

Familial periodic fevers, known as autoinflammatory syndromes, present with recurrent fevers and inflammation. Early clinical suspicion and molecular diagnosis are key for improved patient treatment and outcomes.

Area of Science:

  • Autoinflammatory syndromes
  • Immunology
  • Genetics

Context:

  • Familial periodic fevers are rare autoinflammatory syndromes.
  • Characterized by recurrent systemic inflammation without infection or autoantibodies.
  • Often present with non-specific symptoms and elevated acute phase reactants.

Purpose:

  • To highlight the importance of recognizing autoinflammatory syndromes in clinical practice.
  • To emphasize the role of molecular diagnosis in managing these conditions.
  • To provide a new perspective on treatment and prognosis.

Summary:

  • Autoinflammatory syndromes, including familial periodic fevers, are characterized by recurrent episodes of systemic inflammation.
  • Diagnosis relies on clinical suspicion, exclusion of infection/autoimmunity, and elevated inflammatory markers.
