Increased Body Temperature01:25

Increased Body Temperature

665
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 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 fever

661
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.

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Summary
This summary is machine-generated.

Occupational exposures can cause fevers, including hypersensitivity pneumonitis (HP) from organic dusts and metal fume fever from inorganic substances. Recognizing these occupational fevers is crucial for diagnosis and preventing severe lung disease.

Area of Science:

  • Occupational Medicine
  • Pulmonary Medicine
  • Toxicology

Background:

  • Febrile conditions are often infectious but can stem from occupational exposures.
  • A thorough occupational history is vital for diagnosing exposure-related fevers.
  • Hypersensitivity pneumonitis (HP) and organic dust toxic syndrome (ODTS) are key considerations for organic dust exposure.

Purpose of the Study:

  • To highlight the importance of occupational history in diagnosing febrile conditions.
  • To differentiate between hypersensitivity pneumonitis (HP) and organic dust toxic syndrome (ODTS).
  • To discuss metal fume fever as a distinct occupational febrile illness.

Main Methods:

  • Review of clinical presentations and diagnostic considerations for occupational fevers.
  • Differential diagnosis of interstitial lung disease with unclear etiology.
  • Emphasis on occupational history taking as a diagnostic tool.

Main Results:

  • Occupational exposures, particularly to organic dusts, can lead to significant lung conditions like HP.
  • HP requires timely diagnosis to prevent severe outcomes, including potential lung transplantation.
  • Organic dust toxic syndrome (ODTS) and metal fume fever are distinct syndromes with specific triggers and prognoses.

Conclusions:

  • Occupational history is paramount in identifying the etiology of febrile illnesses.
  • Hypersensitivity pneumonitis (HP) is a serious occupational lung disease that must be considered in unexplained interstitial lung disease.
  • Metal fume fever, though usually benign, presents with characteristic flu-like symptoms following inorganic dust inhalation.
