Summary
Peristomal dermatitis, common in ostomates, is often irritant contact dermatitis. Patch testing revealed allergies to preservatives and fragrances are infrequent causes of this skin condition.
Area of Science:
- Dermatology
- Ostomy Care
Background:
- Skin disorders are a frequent complication for individuals with ostomies, contributing to over a third of stoma nurse consultations.
- Irritant contact dermatitis is the most prevalent skin issue, accounting for more than 50% of problems in some studies.
Purpose of the Study:
- To document the experience and findings of patch testing for peristomal dermatitis.
Main Methods:
- Patients were identified from a specialized skin-stoma clinic database.
- Patch testing was conducted using various chemicals, and the results were analyzed.
Main Results:
- Out of 850 ostomy patients, 149 underwent patch testing.
- Only 4.7% (seven patients) showed relevant positive reactions, none linked to stoma appliance components.
- Preservatives and fragrances were the most common allergens identified.
Conclusions:
- Distinguishing allergic from irritant contact dermatitis is challenging in the occluded peristomal area due to similar clinical presentations.
- Allergic reactions are uncommon causes of peristomal dermatitis, despite continuous skin exposure to ostomy care products.

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:

01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:23Skin 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...
