Insights

An outbreak of fungal peritonitis in chronic ambulatory peritoneal dialysis (CAPD) patients was linked to Candida parapsilosis. Environmental contamination, including pigeon guano, was identified as the source, leading to improved containment measures.

Area of Science:

  • Infectious Diseases
  • Nephrology
  • Mycology

Background:

  • Fungal peritonitis is a serious complication in patients undergoing chronic ambulatory peritoneal dialysis (CAPD).
  • Candida parapsilosis has emerged as a significant cause of fungal infections in healthcare settings.

Purpose of the Study:

  • To investigate an outbreak of fungal peritonitis in CAPD patients.
  • To identify the source and transmission route of Candida parapsilosis causing the peritonitis.

Main Methods:

  • Retrospective analysis of 12 CAPD patients with fungal peritonitis.
  • Microbiological investigation of the CAPD unit, medical ward, and environmental samples.
  • Treatment involved CAPD catheter removal and systemic antifungal therapy.

Main Results:

  • All 12 patients received treatment, with no peritonitis-related deaths.
  • Candida parapsilosis was isolated from the CAPD unit, ward, and pigeon guano.
  • Installation of bird-proof netting correlated with a decrease in peritonitis cases.

Conclusions:

  • Pigeons carrying Candida parapsilosis in their feces likely contaminated the CAPD environment, leading to the outbreak.
  • Environmental control measures, such as bird-proofing, are crucial in preventing fungal peritonitis in CAPD units.
  • Prompt diagnosis and treatment, including catheter removal and antifungal therapy, are essential for patient outcomes.

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
