Insights

Prosthetic joint infections from Brucella species are uncommon. This case highlights a rare instance of Brucella prosthetic joint infection occurring fourteen years after initial treatment for systemic brucellosis.

Area of Science:

  • Infectious Diseases
  • Orthopedics
  • Microbiology

Background:

  • Brucellosis is a zoonotic infection caused by Brucella species.
  • Prosthetic joint infections (PJIs) are serious complications of orthopedic surgery.
  • Brucella species are an infrequent cause of PJIs.

Observation:

  • A patient presented with a prosthetic joint infection 14 years after successful treatment for systemic brucellosis.
  • The infection involved a previously implanted prosthetic joint.

Findings:

  • This case demonstrates a rare late-onset prosthetic joint infection due to Brucella species.
  • The findings suggest that Brucella can remain dormant or cause delayed infections in prosthetic joints.

Implications:

  • Clinicians should consider Brucella as a potential pathogen in late-presenting prosthetic joint infections, even years after initial treatment.
  • This case underscores the importance of long-term follow-up for patients treated for brucellosis, particularly those with prosthetic implants.
  • Further research may elucidate mechanisms of delayed Brucella PJI and inform diagnostic and therapeutic strategies.

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: 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...
