Acute Pharyngitis01:30

Acute Pharyngitis

2.4K
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:

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

212
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Esophageal Strictures-II: Clinical Features and Management

222
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

1.1K
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...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Summary

Severe dysphagia, or difficulty swallowing, is a key predictor of fever after stroke. Early identification and management of swallowing problems can help reduce fever in stroke patients.

Area of Science:

  • Neurology
  • Clinical Medicine
  • Swallowing Disorders

Background:

  • Post-stroke fever is common and linked to poorer outcomes.
  • Potential causes include infections, stroke severity, comorbidities, and dysphagia.
  • Dysphagia's role in post-stroke fever requires detailed investigation.

Purpose of the Study:

  • To determine if dysphagia severity, assessed through detailed swallowing evaluation, predicts post-stroke fever.
  • To identify specific swallowing parameters associated with fever development after stroke.

Main Methods:

  • Retrospective monocentric cohort study of 923 ischemic or hemorrhagic stroke patients.
  • Detailed, standardized swallowing assessment including clinical exams and fiberoptic endoscopic evaluation.
  • Comparison of patients with and without fever regarding swallowing parameters and clinical characteristics.

Main Results:

  • 13.8% of patients developed fever within 5 days.
  • Moderate-to-severe dysphagia (OR 3.05) and dysphagia with aspiration risk (OR 1.79) independently predicted fever.
  • Stroke severity and urinary catheter use also predicted fever.

Conclusions:

  • Detailed dysphagia assessment, including instrumental testing, predicts post-stroke fever.
  • Early identification and management of severe dysphagia may reduce fever incidence.
  • This highlights dysphagia as a critical factor in post-stroke fever development.
