Homeostatic Imbalances in Body Temperature

Homeostatic Imbalances in Body Temperature

Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

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...

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:

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:

Disorders of Hemostasis

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Decreased Body Temperature

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Summary

This summary is machine-generated.

Pseudothrombocytosis, a spurious high platelet count, can be caused by leukocyte fragments, especially in heatstroke cases. Peripheral blood smear analysis and fluorescence platelet counts help identify this artifact.

Area of Science:

Hematology
Clinical Pathology
Medical Diagnostics

Background:

Spurious results in hematology analyzers can lead to misdiagnosis.
Pseudothrombocytosis, falsely elevated platelet counts, is a known artifact.
Abnormal cell cytoplasm has been previously implicated in pseudothrombocytosis.

Observation:

A rare case of pseudothrombocytosis was observed in a patient with heatstroke.
The condition was linked to fragments of mature leukocytes.
Discrepancies between fluorescence (PLT-F) and impedance (PLT-I) channels were noted.

Findings:

Leukocyte fragments, not platelets, were the cause of the elevated platelet count.
Peripheral blood smear analysis confirmed the presence of these fragments.
The PLT-F channel effectively differentiated true platelets from leukocyte fragments.

Implications:

Accurate identification of pseudothrombocytosis is crucial for correct diagnosis and treatment.
Heatstroke can present with unusual hematological findings.
Utilizing both peripheral blood smear review and advanced analyzer channels improves diagnostic accuracy.
