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.
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:
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.

Patterns of Fever

Before understanding the types and patterns of fever, it is essential to know its phases.
Acute Pyelonephritis I: Introduction01:27

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Summary
This summary is machine-generated.

Fever in infants requires prompt evaluation, especially in neonates and those with risk factors like sickle cell disease. Early identification and management of serious infections, including MRSA and HSV, are crucial for preventing severe outcomes.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Emergency Medicine

Background:

  • Fever is a common pediatric symptom, defined as a rectal temperature >38.0°C (100.4°F).
  • Home-documented fevers require similar management as those in the Emergency Department (ED).
  • Certain populations, including neonates and children with sickle cell disease, are at higher risk for serious febrile illness.

Purpose of the Study:

  • To outline the evaluation and management of pediatric fever.
  • To identify high-risk populations and specific pathogens requiring urgent attention.
  • To emphasize the importance of considering less common but serious causes of fever.

Main Methods:

  • Review of current guidelines and literature on pediatric fever management.
  • Discussion of diagnostic criteria for sepsis workup in infants.
  • Highlighting clinical and laboratory indicators for risk stratification.

Main Results:

  • Febrile infants <28 days old require a full sepsis workup and parenteral antibiotics.
  • Low-risk infants aged 1-4 months can be identified using clinical/laboratory criteria.
  • Consideration of Methicillin-resistant Staphylococcus aureus (MRSA) and Herpes Simplex Virus (HSV) infections is essential.

Conclusions:

  • Prompt and appropriate management of pediatric fever is critical.
  • Risk stratification aids in determining the intensity of workup and treatment.
  • Awareness of specific pathogens like MRSA and HSV improves patient outcomes.
