Insights

A rare fungal infection, Gibellulopsis nigrescens, caused peritonitis in a patient on peritoneal dialysis. Touch contamination from a caregiver's scalp infection was confirmed as the source.

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Nephrology

Background:

  • Peritoneal dialysis (PD) is a vital treatment for kidney failure.
  • Fungal peritonitis is a rare but serious complication of PD.
  • Identifying the source of fungal pathogens is crucial for effective treatment.

Observation:

  • A case of PD-associated peritonitis caused by Gibellulopsis nigrescens is reported.
  • The same fungal species was identified in the patient's caregiver, who had tinea capitis.
  • DNA barcoding confirmed the identical species in both infections.

Findings:

  • Touch contamination from the caregiver's tinea capitis was identified as the source of G. nigrescens peritonitis.
  • The patient recovered after PD catheter removal and systemic amphotericin B treatment.
  • DNA barcoding is effective for identifying fungal pathogens in clinical settings.

Implications:

  • Highlights the risk of fungal infections through caregiver-to-patient touch contamination.
  • Emphasizes the importance of stringent hygiene practices in PD settings.
  • Suggests antifungal prophylaxis or enhanced screening in high-risk caregiver-patient scenarios.

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Ostomy Care

Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
