Decreased Body Temperature01:29

Decreased Body Temperature

620
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...

Methods of reducing fever01:22

Methods of reducing fever

665
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.

Increased Body Temperature01:25

Increased Body Temperature

675
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...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

129
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...

Thermoregulation01:26

Thermoregulation

1.0K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Area of Science:

  • Geriatrics
  • Internal Medicine
  • Pathophysiology

Context:

  • Hypothermia in older patients presents significant morbidity and mortality risks.
  • It frequently signifies atypical presentations of underlying medical conditions.
  • Common causes include infection and accidental exposure to cold.

Purpose:

  • To highlight hypothermia as a key symptom in atypical presentations of underlying conditions in the elderly.
  • To emphasize the importance of prompt diagnostic workups and empirical antibiotic treatment.
  • To guide clinicians in considering non-infectious causes when antibiotics are ineffective.

Summary:

  • Presents two cases of hypothermia in older patients with atypical underlying conditions.
  • Underscores the necessity of thorough diagnostics for infectious diseases and other potential causes.
  • Advocates for prompt initiation of antibiotics and consideration of alternative diagnoses if infections are ruled out or unresponsive.

Impact:

  • Enhances clinical awareness of hypothermia's diverse etiologies in geriatric populations.
  • Promotes timely and appropriate diagnostic strategies for elderly patients presenting with hypothermia.
  • Aims to improve management and reduce mortality associated with hypothermia in older adults.
