Insights

Group B Streptococcus (GBS) can cause invasive infections, like large pelvic abscesses, even in non-pregnant adults without underlying conditions. Prompt diagnosis and treatment with antibiotics and image-guided drainage are crucial for successful outcomes.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Radiology

Background:

  • Group B Streptococcus (GBS) typically affects neonates, pregnant women, and immunocompromised adults.
  • GBS is an opportunistic pathogen with a broad host range.
  • Invasive GBS infections are less common in non-pregnant, otherwise healthy adults.

Purpose of the Study:

  • To report a rare case of a large pelvic abscess caused by Group B Streptococcus in a non-pregnant patient without comorbidities.
  • To highlight the importance of considering GBS in the differential diagnosis of abscesses in diverse patient populations.
  • To emphasize the successful management of such infections.

Main Methods:

  • Interventional radiology (IR) guided drainage of the pelvic abscess.
  • Administration of appropriate antibiotic therapy.
  • Microbiological analysis to identify the causative organism.

Main Results:

  • Successful treatment of a large pelvic abscess caused by Group B Streptococcus.
  • The patient, a non-pregnant adult without underlying medical conditions, recovered fully.
  • Image-guided drainage and targeted antibiotics proved effective.

Conclusions:

  • Group B Streptococcus can cause severe, invasive infections, such as large pelvic abscesses, in non-pregnant individuals without comorbidities.
  • Empirical antibiotic coverage for GBS should be considered in patients presenting with abscesses, regardless of traditional risk factors.
  • Interventional radiology plays a key role in the management of complex abscesses.

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...

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...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
