Types of Fever01:25

Types of Fever

775
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

6.0K
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...

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.

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:

Acute Pyelonephritis I: Introduction01:27

Acute Pyelonephritis I: Introduction

195
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...

    Area of Science:

    • Internal Medicine
    • Clinical Diagnostics

    Background:

    • Fever of unknown origin (FUO) is a rare clinical syndrome posing significant diagnostic challenges.
    • Over 200 diseases can manifest as FUO, broadly categorized into infections, non-infectious inflammatory diseases, malignancies, and miscellaneous disorders.

    Purpose of the Study:

    • To provide up-to-date clinical research evidence on FUO.
    • To propose a concise, clue-oriented diagnostic approach for FUO.

    Main Methods:

    • Review of clinical research evidence.
    • Analysis of characteristic symptoms, clinical signs, and laboratory findings associated with FUO categories.

    Main Results:

    • Individual diagnostic clues for FUO are often non-specific.
    • Effective interpretation of hallmark clinical features within a differential diagnostic context is crucial.

    Conclusions:

    • A systematic, clue-oriented approach can aid in the diagnosis of FUO.
    • Clinicians must identify and correctly interpret clinical features to navigate the diagnostic complexities of FUO.
