Increased Body Temperature01:25

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.
Decreased Body Temperature01:29

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...
Methods of reducing fever01:22

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.

Homeostatic Imbalances in Body Temperature01:19

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...
Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Area of Science:

  • Oncology
  • Gastroenterology
  • Medical Devices

Background:

  • Esophageal cancer surgery presents significant challenges, particularly reconstruction using stomach or intestinal tissue, increasing invasiveness and risks for elderly patients.
  • Late diagnosis often precludes surgical intervention for esophageal cancer, limiting treatment options for advanced stages.
  • Current treatments for terminal esophageal cancer, especially when surgery is not feasible, require innovative therapeutic approaches.

Purpose of the Study:

  • To introduce a novel therapeutic device for terminal esophageal cancer patients unsuitable for surgery.
  • To highlight the potential of a noninvasive treatment modality for advanced esophageal malignancy.
  • To evaluate the feasibility of a Swallow Stent with Hyperthermia as an alternative therapy.

Main Methods:

  • Development of a Swallow Stent incorporating a Hyperthermia function.
  • Application of the device in patients with terminal esophageal cancer.
  • Assessment of the stent's noninvasive nature, hyperthermia delivery to carcinoma tissue, and restoration of swallowing function.

Main Results:

  • The developed Swallow Stent is completely noninvasive.
  • The device effectively delivers hyperthermia directly to the esophageal carcinoma tissue.
  • The stent successfully restores the patient's swallowing function.

Conclusions:

  • The Swallow Stent with Hyperthermia represents a promising alternative therapy for terminal esophageal cancer.
  • This innovative device addresses the limitations of traditional surgical interventions for advanced cases.
  • Further research and clinical trials are warranted to establish its efficacy and role in esophageal cancer management.
