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 sustained extreme cold exposure, and severe...

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.

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...

Factors Affecting Body Temperature

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

Assessing Body Temperature - Axilla

Assessing Body Temperature - Axilla

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

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.

Summary

This case study highlights a rare association between thymoma and persistent hypothermia. Investigating thymoma is crucial when other causes of low body temperature are ruled out.

Background:

Thymomas are rare, slow-growing tumors with diverse presentations, including paraneoplastic syndromes.
Paraneoplastic disorders associated with thymoma often involve autoantibodies, leading to conditions like myasthenia gravis or hypogammaglobulinemia.
Persistent hypothermia is an exceptionally rare presentation of thymoma, with only one prior case reported.

Purpose of the Study:

To report a second case of thymoma associated with persistent hypothermia.
To emphasize the importance of considering thymoma in the differential diagnosis of unexplained hypothermia.

Main Methods:

Case presentation of an 88-year-old male with Type A thymoma and persistent hypothermia.
Comprehensive investigation to exclude other causes of hypothermia.
Symptomatic management of hypothermia with rewarming and management of pleural effusion.

Main Results:

The patient's persistent hypothermia was found to be solely attributable to the thymoma.
Symptoms of hypothermia were effectively managed with external rewarming techniques.
Dyspnea improved following pleural effusion management and talc pleurodesis.

Conclusions:

Thymoma should be considered in the differential diagnosis of unexplained hypothermia, particularly after common causes have been excluded.
This case adds to the limited literature on the association between thymoma and hypothermia, suggesting a potential autoimmune or regulatory mechanism.
