Increased Body Temperature01:25

Increased Body Temperature

663
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:

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

121
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...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

3.4K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

377
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Area of Science:

  • Endocrinology
  • Internal Medicine
  • Pathophysiology

Background:

  • Fever is commonly attributed to infectious or inflammatory causes.
  • Endocrine disorders are often overlooked as potential sources of fever.
  • Understanding the link between endocrine system and fever is crucial for comprehensive diagnosis.

Purpose of the Study:

  • To explore the multifaceted connections between fever and endocrine dysfunction.
  • To introduce the concept of 'endocrine fever' encompassing various endocrine-related febrile conditions.
  • To highlight the importance of considering endocrine etiologies in unexplained fever.

Main Methods:

  • Literature review of endocrine disorders associated with fever.
  • Analysis of clinical presentations linking endocrine dysfunction and fever.
  • Categorization of fever causes within endocrine pathologies and treatments.

Main Results:

  • Impaired resistance to infection in conditions like diabetes and Cushing's syndrome can cause fever.
  • Specific endocrine disorders such as hyperthyroidism, subacute thyroiditis, carcinoid syndrome, and pheochromocytoma can present with fever.
  • Fever is an adverse effect of certain endocrine treatments, including bisphosphonates and antithyroid drugs.

Conclusions:

  • 'Endocrine fever' is a recognized phenomenon linking endocrine dysfunction and febrile states.
  • Increased awareness of these associations can improve diagnostic accuracy for fever of unknown origin.
  • Prompt diagnosis and management of endocrine fever can lead to better patient outcomes.
