Increased Body Temperature01:25

Increased Body Temperature

859
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...

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:

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:

Asthma-III: Symptoms and Complications

2.6K
Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Summary

Influenza-like illness can mask serious conditions like osteomyelitis. Consider broader diagnoses in patients with prolonged or focal flu symptoms, especially those appearing critically ill.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Radiology

Background:

  • Emergency departments often diagnose influenza (flu) solely based on typical symptoms during flu season.
  • This can lead to overlooking serious conditions that mimic flu but require different management.
  • It is crucial to consider alternative diagnoses in patients presenting with atypical or prolonged flu-like symptoms.

Purpose of the Study:

  • To highlight the importance of considering non-influenza diagnoses in pediatric patients with severe or prolonged flu-like symptoms.
  • To present a case of frontal bone osteomyelitis initially presenting as influenza-like illness.

Main Methods:

  • Case report of an 11-year-old male with prolonged flu-like symptoms.
  • Laboratory tests revealed influenza type B and elevated inflammatory markers.
  • Imaging studies, including sinus CT, were performed due to symptom severity and progression.

Main Results:

  • The patient initially presented with typical influenza symptoms but developed frontal forehead edema.
  • Sinus CT confirmed frontal bone osteomyelitis.
  • Despite surgical drainage, the patient experienced recurrent abscesses and superior sagittal sinus thrombosis.

Conclusions:

  • Prolonged or focal flu-like symptoms, particularly in ill-appearing children, warrant a broader differential diagnosis.
  • Osteomyelitis and other serious infections should be considered when symptoms deviate from typical influenza presentations.
  • Early and comprehensive investigation is vital to prevent severe complications.
