Deglutition01:25

Deglutition

6.6K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

1.1K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.1K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

2.0K
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...

Glucose Transporters01:27

Glucose Transporters

27.8K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Summary
This summary is machine-generated.

Swallowing can trigger fainting (deglutition syncope) due to vagus nerve stimulation. A hiatal hernia causing an intrathoracic stomach was identified as the cause in one patient.

Area of Science:

  • Neurology
  • Gastroenterology
  • Cardiology

Background:

  • Deglutition syncope is a rare neurally mediated reflex syndrome.
  • It involves the vagus nerve's influence on the heart, esophagus, and stomach.
  • Swallowing can inhibit the cardiac conduction system, leading to syncope.

Observation:

  • The case involved a 48-year-old man experiencing syncopal episodes while eating.
  • These episodes were linked to an intrathoracic stomach.
  • The underlying cause was identified as a hiatal hernia.

Findings:

  • The patient's syncope was directly caused by an intrathoracic stomach due to a hiatal hernia.
  • This case highlights an unusual cause of deglutition syncope.
  • Esophageal disorders are common causes, but anatomical abnormalities can also play a role.

Implications:

  • This case expands the understanding of deglutition syncope causes.
  • It emphasizes the importance of considering anatomical abnormalities in diagnosing swallow syncope.
  • Accurate diagnosis and management of hiatal hernias may prevent recurrent syncopal episodes.
