Cultured epidermal allografts: Quantitative evaluation of their healing effect in deep dermal burns.

This study summarizes the Brno Burn Centre experience with the application of cultured epidermal allografts (CEAl) in the treatment of deep dermal burns. In a prospective randomised trial on 30 patients with deep dermal burns CEAl obtained from young healthy and examined donors and fixed on tulle grass carrier (Grasolind) were compared with empty Grasolind as the lowest layer of dressing. All the other layers were identical.

The influence of moisture wound healing on the incidence of bacterial infection and histological changes in healthy human skin after treatment of interactive dressings.

In this article the authors discuss the problem faced by physicians when trying to use moisture-retentive dressing in pressure sores (decubitus ulcers). First, they report the results of an in vitro study using a new model of experimental wound (radio-isotopic investigation) that assesses the release of Ringer's solution from interactive dressings continually during fourteen hours. Second, they perform an animal experiment that assesses the incidence of wound infection in defects treated conventionally or using interactive dressings.

Special features of burn injuries in elderly patients.

Types of burns and other aspects of burn injuries and case outcomes were assessed in a group of geriatric patients (> 60 years) and a younger group of patients (40-59 years). Between 1990 and 1999, 137 geriatric patients (47 [34%] males and 90 [66%] females) were admitted to the Burn Centre and Reconstructive Surgery Centre at University Hospital in Brno. We compared findings in this elderly group to those in 176 younger burn patients (126 [72%] males and 50 [28%] females) who were treated at the centre during the same time period.

Our experience with transconjunctival, laser-assisted lower blepharoplasty.

Introduction: Transconjunctival lower blepharoplasty has become more popular in the last decade with the introduction of the CO2 laser as a cutting and resurfacing tool. The authors have 4 years experience with this procedure.

Method: Patient selection, preoperative evaluation and the surgical technique are described in detail.

[The moist wound healing system in an experiment and clinical practice].

We compared two types of moisture-retentive dressings (dressings that are capable of maintaining a moist environment) in wound healing. The conventional method of using an impregnated gauze in combination with a moist wound dressing was compared with TenderWet. First, we report results from an in vitro study and an animal experiment that included assessment of reepithelization and incidence of wound infection.

[Use of skin substitutes in treatment of large hypertrophic scars due to burn injury].

The study concerns a clinical experiment in two patients with a dermal substitute based on atelocollagen and hyaluronic acid, and allogeneic acellular dermis. In both cases two-step grafting was performed. At the first step the dermal substitute was implanted into the wound and it was grafted at the second step with thin dermoepidermal autograft.

[Antimicrobial activity of composite filling materials].

Antimicrobial effects of several composite fillers are monitored in response to a mixed aerobic and anaerobic microbial flora of the oral cavity. None of observed both self-polymerizing and photopolymerizing composites showed antimicrobial effects.
