Evaluating the Irritant Factors of Silicone and Hydrocolloid Skin Contact Adhesives Using Trans-Epidermal Water Loss, Protein Stripping, Erythema, and Ease of Removal

A composite silicone skin adhesive material was designed to improve its water vapor permeability to offer advantages to wearer comfort compared to existing skin adhesive dressings available (including perforated silicone and hydrocolloid products). The chemical and mechanical properties of this novel dressing were analyzed to show that it has a high creep compliance, offering anisotropic elasticity that is likely to place less stress on the skin. A participant study was carried out in which 31 participants wore a novel silicone skin adhesive (Sil2) and a hydrocolloid competitor and were monitored for physiological response to the dressings. Trans-epidermal water loss (TEWL) was measured pre- and postwear to determine impairment of skin barrier function. Sil2 exhibited a higher vapor permeability than the hydrocolloid dressings during wear. Peel strength measurements and dye counter staining of the removed dressings showed that the hydrocolloid had a higher adhesion to the participants' skin, resulting in a greater removal of proteins from the stratum corneum and a higher pain rating from participants on removal. Once the dressings were removed, TEWL of the participants skin beneath the Sil2 was close to normal in comparison to the hydrocolloid dressings that showed an increase in skin TEWL, indicating that the skin had been highly occluded. Analysis of the skin immediately after removal showed a higher incidence of erythema following application of hydrocolloid dressings (>60%) compared to Sil2, (<30%). In summary, this modified silicone formulation demonstrates superior skin protection properties compared to hydrocolloid dressings and is more suitable for use as a skin adhesive.

Analgesic effect of structured anal skin care for perianal dermatitis after low anterior resection in the rectal cancer patients: prospective, single-center, open-label, therapeutic confirmatory, randomized clinical trial

Purpose

This prospective, single-center, open-label, therapeutic confirmatory, randomized clinical trial aimed to assess the alleviation of anal pain by applying structured anal skin care including skin protectants in rectal cancer patients with low anterior resection syndrome (LARS) combined with anal pain.

Methods

From December 2017 to May 2020, 42 patients with LARS (scores of ≥21) and anal pain (visual analogue scale [VAS] score of ≥3) were randomly assigned and observed for 4 weeks. The conventional treatment consisted of dietary management, sitz baths, prohibition of anal scrubbing, loperamide, and dioctahedral smectite. In the anal care group, cleanser, barrier cream, and barrier spray were applied to the anal skin after defecation following the conventional treatment. The primary outcome was analgesic effect on anal pain after 2 weeks of structured treatment (anal care group) or conventional (control group). The cutoff for analgesic effect was a decrease in the anal pain score (VAS score of ≥2 or ≥30% reduction).

Results

As a primary outcome, the analgesic effect was significantly higher in the anal care group (P = 0.034). The incontinence-associated dermatitis skin condition score was significantly improved in the anal care group than control group after 4 weeks (P = 0.023). There were no significant differences in LARS scores and quality of life scores between 2 groups.

Conclusion

Structured anal skin care has a significant analgesic effect in reducing anal pain and improving anal skin conditions in patients with LARS after rectal cancer surgery.

A new approach with a novel silicone adhesive stoma bag: a clinical study on peristomal skin and quality of life

The care of peristomal skin is a major challenge for people living with a stoma, as well as stoma care nurses. Peristomal skin complications include medical adhesive-related skin injuries/skin stripping, moisture-associated skin damage and contact dermatitis. There is also a limited choice of hydrocolloid adhesive stoma bags. This article reports on the introduction of Genii™, a new stoma bag that sticks with a unique breathable silicone adhesive. The study investigated the experiences of 61 colostomates over a 6-week period, examining the effect on their peristomal skin and their quality of life, in terms of sleep, self-image, social confidence and exercise, and overall product performance. The majority of study participants reported a positive experience when using the stoma bag.

Novel stoma appliances to minimise complications and improve patient outcomes

Stomas are created for a number of reasons and, if they are formed without the opportunity for preoperative care and consideration, such as siting, stoma care needs can be more complex in the long term. Patient quality of life can be negatively affected by the incidence of stoma related complications, such as leakage or sore skin. A new range of products, Aura Plus, distributed by CliniMed Ltd in the UK, were evaluated on more than 200 patients with a stoma and assessed for comfort, ease of application, security and leakage. Case studies highlight positive patient outcomes following the use of Aura Plus, and demonstrate how Aura Plus can benefit patients experiencing different needs with their stoma care, such as leakage, peristomal skin complications or a parastomal hernia.
