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.

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.
Pharmacological Methods of Reducing Fever:

Burn Injuries

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

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:

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

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:
Classification of Asthma

Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Summary

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) persist in developing nations. Secondary prophylaxis within coordinated programs is the most effective control strategy, as vaccines remain distant.

Area of Science:

Cardiology
Infectious Diseases
Public Health

Background:

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are rare in affluent nations but prevalent in developing countries and marginalized populations.
Over a century of research has improved understanding, yet epidemiological shifts necessitate updated perspectives and data from high-incidence regions.
Current diagnostic guidelines are being adapted for increased sensitivity in high-ARF populations.

Purpose of the Study:

To address the need for updated understanding of ARF and RHD in light of epidemiological shifts.
To highlight the necessity of improved data from developing countries.
To explore new strategies for primary prevention and effective control programs.

Main Methods:

Review and synthesis of existing research on ARF and RHD epidemiology and management.
Analysis of current diagnostic guideline adaptations.
Evaluation of primary and secondary prevention strategies.

Main Results:

ARF and RHD remain significant public health issues in specific global populations.
Vaccine development faces considerable challenges in serotype coverage, safety, and accessibility.
Primary prophylaxis has limitations as a population-based strategy.

Conclusions:

New primary prevention approaches are essential.
Secondary prophylaxis, integrated into coordinated programs, is the most effective method for controlling ARF and RHD.
Further research and data from developing countries are crucial for effective disease control.
