Types of Fever

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 Temperature

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.

Patterns of Fever

Patterns of Fever

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

Methods of reducing fever

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.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Acute Pharyngitis

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Summary

The heptavalent pneumococcal conjugate (PCV7) vaccine has significantly reduced bacteremia in young children, shifting the focus of fever causes to urinary tract infections and necessitating updated management guidelines.

Area of Science:

Pediatrics
Infectious Diseases
Immunology

Background:

Fever in children under 3 years old is a common clinical presentation.
Previous management guidelines were based on higher rates of bacteremia.

Purpose of the Study:

To review the impact of PCV7 vaccine and viral detection methods on fever management in young children.
To highlight changes in the epidemiology of serious infections.

Main Methods:

Review of literature published since 2002.
Analysis of changes in bacteremia rates post-PCV7 introduction.
Discussion of diagnostic advancements like PCR for viral identification.

Main Results:

PCV7 vaccine introduction led to a decrease in bacteremia to 1%.
Urinary tract infections are now the most common cause of fever in this age group.
PCR testing aids in early viral diagnosis and reduces antibiotic overuse.

Conclusions:

Current fever management guidelines for children under 3 require revision due to decreased bacteremia.
Development of better markers for predicting serious bacterial infections is needed.
Further research on host immune responses is crucial.
