Summary
A woman developed allergic gastritis from dental work. Replacing her gold, palladium, and zirconium crowns with titanium resolved her stomach pain, suggesting a delayed-type allergy to dental materials.
Area of Science:
- Allergy and Immunology
- Gastroenterology
- Dental Materials Science
Background:
- Contact allergic gastritis is rare, particularly in patients with nickel allergy.
- Dental restorations can contain various metals, posing potential risks for allergic reactions.
Observation:
- A 46-year-old woman presented with gastrointestinal complaints and lichenoid mucosal lesions after receiving new dental crowns and bridges.
- Gastroscopy revealed eosinophilic gastritis, and patch testing showed allergies to gold, palladium, and zirconium, among other metals.
Findings:
- The patient's dental work contained gold, palladium, and zirconium chloride.
- Replacing the metal-containing dental restorations with titanium-based ones led to the complete resolution of her gastrointestinal symptoms.
Implications:
- Delayed-type hypersensitivity to dental materials can manifest as allergic gastritis.
- Careful material selection and allergy testing are crucial in patients with unexplained gastrointestinal symptoms and dental work.

01:27Gastritis-I: Introduction and Types
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

01:23Gastritis III: Clinical Manifestations and Management
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...

01:17Gastritis-II: Pathophysiology
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:29Gastroesophageal Reflux Disease II: Clinical Features and Management
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.

01:30Other Disorders of Digestive System
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...
