Insights

Haemophilus parainfluenzae bacteremia is rare but occurred in a teen after ERCP and cholecystectomy. Prompt IV ceftriaxone treatment led to recovery and abscess resolution.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Infectious Diseases

Background:

  • Haemophilus parainfluenzae commonly colonizes the human respiratory tract.
  • Gastrointestinal infections and bacteremia are uncommon manifestations of H. parainfluenzae.

Observation:

  • A 17-year-old male developed H. parainfluenzae bacteremia and an intraabdominal abscess.
  • This occurred within three days of undergoing ERCP with sphincterotomy and elective cholecystectomy.

Findings:

  • The patient presented with H. parainfluenzae bacteremia and intraabdominal abscess post-procedurally.
  • Treatment with intravenous ceftriaxone resulted in symptom improvement and abscess resolution.

Implications:

  • This case highlights a rare pediatric infection following specific gastrointestinal procedures.
  • It underscores the convergence of risk factors for H. parainfluenzae bacteremia in a single patient.

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

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...

Acute Pyelonephritis I: Introduction01:27

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

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.
