Insights

Meningococcal W infections are rising in Europe. This case highlights isolated hip arthritis caused by meningococcal W135 in a child, without other invasive disease symptoms.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Rheumatology

Background:

  • Invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup W (MenW) has increased in Europe.
  • While sepsis and meningitis are common, focal complications like arthritis can also occur.

Observation:

  • A 6-year-old patient presented with isolated arthritis of the hip.
  • The patient did not exhibit signs of invasive meningococcal disease such as sepsis or meningitis.

Findings:

  • The arthritis was confirmed to be caused by meningococcal serotype W135 (MenW135).
  • This represents a rare presentation of focal meningococcal infection without systemic invasive disease.

Implications:

  • Highlights the importance of considering meningococcal W135 as a cause of isolated arthritis in children.
  • May prompt earlier diagnosis and appropriate antibiotic treatment for focal meningococcal infections.

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...
