Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.9K
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...

Endocarditis II: Clinical Features of Infective Endocarditis

929
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Esophageal Achalasia01:27

Esophageal Achalasia

45
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide...

Chronic Pharyngitis01:23

Chronic Pharyngitis

16.7K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Acute Pharyngitis

6.6K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

52
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...

Area of Science:

  • Oral Medicine
  • Dermatology
  • Pathology

Background:

  • Plasma cell cheilitis is an uncommon inflammatory condition affecting the lips.
  • It is histologically defined by a dense dermal infiltrate of mature plasma cells.
  • Clinical presentation typically involves asymptomatic, erythematous-violaceous plaques.

Observation:

  • A case of plasma cell cheilitis is presented in a 58-year-old male.
  • The condition manifested as angular cheilitis, affecting the lateral oral commissure.
  • The lesions were characterized by ulcerated plaques.

Findings:

  • Histopathological examination revealed a significant dermal infiltrate composed of mature plasma cells.
  • The clinical and histological findings confirmed the diagnosis of plasma cell angular cheilitis.
  • The asymptomatic nature of the plaques was noted.

Implications:

  • This case expands the understanding of the clinical spectrum of plasma cell cheilitis.
  • It underscores the importance of considering plasma cell cheilitis in the differential diagnosis of angular cheilitis.
  • Further research may elucidate specific triggers or management strategies for this rare condition.
