Insights

Abdominal pain in children with Group A streptococcal (GAS) pharyngitis may be caused by mesenteric lymphadenitis (mLAD). Point-of-care ultrasound (POCUS) identified mLAD in pediatric patients with GAS pharyngitis and abdominal pain.

Area of Science:

  • Pediatric Emergency Medicine
  • Infectious Diseases
  • Diagnostic Imaging

Background:

  • Abdominal pain is a frequent symptom in pediatric patients diagnosed with Group A streptococcal (GAS) pharyngitis.
  • The underlying cause of abdominal pain associated with GAS infections remains unclear.
  • Point-of-care ultrasound (POCUS) is a valuable tool utilized by pediatric emergency physicians for evaluating abdominal pain in children.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
