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 as Proteus,...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Area of Science:

  • Ophthalmology
  • Infectious Diseases

Background:

  • Dacryocystitis commonly presents as pre-septal cellulitis.
  • Orbital abscesses are rare complications due to anatomical barriers.

Purpose of the Study:

  • To report a rare case of dacryocystitis presenting as post-septal cellulitis.
  • To highlight the importance of considering orbital abscess in specific patient populations.

Main Methods:

  • Case report of a postmenopausal woman with dacryocystitis and underlying malignancy.
  • Treatment involved antibiotic therapy and dacryocystorhinostomy.

Main Results:

  • The patient presented with post-septal cellulitis, a rare manifestation of dacryocystitis.
  • Successful management with antibiotics and surgery prevented recurrence.

Conclusions:

  • Orbital abscess should be considered in postmenopausal women with dacryocystitis.
  • Prompt diagnosis and surgical intervention are vital to prevent vision loss.
