Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

2.5K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

550
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Gastritis III: Clinical Manifestations and Management

1.1K
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

488
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Conditioned Taste Aversion01:14

Conditioned Taste Aversion

473
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.2K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Area of Science:

  • Gastroenterology
  • Emergency Medicine
  • Medical Imaging

Background:

  • A previously healthy 57-year-old male experienced acute onset of over 10 episodes of vomiting.
  • Symptoms began 6 hours prior to emergency department presentation, following a large meal.

Observation:

  • Physical examination revealed epigastric tenderness.
  • Vital signs were unremarkable upon presentation.
  • Point-of-care ultrasound (POCUS) of the abdomen was performed, with findings presented in Figure 1.

Findings:

  • Ultrasound images (Figure 1) showed transverse and longitudinal views of the epigastrium.
  • The POCUS findings are critical for differentiating potential diagnoses.

Implications:

  • Accurate and timely diagnosis is essential for appropriate patient management.
  • POCUS serves as a valuable tool in the emergency setting for rapid abdominal assessments.
  • The case highlights the importance of considering various gastrointestinal emergencies presenting with vomiting.
