Impact of Hidradenitis Suppurativa Surgical Treatment on Health-Related Life Quality

(1) Background: Hidradenitis suppurativa is a disease that affects the intimacy of patients. This disease reduces the quality of life and functioning of patients in everyday life. The surgical treatment of HS is one of the treatments for HS that can improve the quality of life. (2) Methods: The main goal of this study was to assess quality of life before the surgical treatment and after the surgical treatment of HS at Center for Burn Treatment in Siemianowice Śląskie, Poland, using the EQ-5D-5L survey before the operation and at follow-up (6 months after). (3) Results: The average quality of life measured with the EQ-5D-5L survey before therapy was 39.3 ± 20.1 (min., 0; max., 60; most frequent value, 50), whereas after surgical treatment, the mean quality of life was 89.5 ± 12.5 (min., 50; max., 100; most frequent value, 100). The average increase in the quality of life was 50.2 ± 19.5 (min., 30; max., 100; most frequent value, 30), and it was statistically significant (p < 0.001)

A Survey of 1000 Respondents on the Polish Population’s Knowledge and Attitudes about Tissue/Organ Donation and Transplantation in Times of Allogeneic Tissue Shortage

Tissue-engineered human allogeneic skin grafts retrieved from a deceased donor play an important role in the therapy of extensive and deeply burned patients. However, there is a vital deficit of allogeneic skin donors, and the reserves of human allogeneic skin grafts are not sufficient. The goal of this work was to analyze the level of knowledge and attitudes of Polish society in the field of transplantation, with particular emphasis on allogeneic skin transplantation. The study used a self-made questionnaire comprised of 23 questions. 1000 respondents took part in this research. The respondents were a diverse group in terms of age, sex, education, and place of residence. The obtained results show a general positive attitude of the respondents towards the idea of transplantology. However, people with lower education presented a more negative attitude towards the donation of tissues and organs. Additionally younger people were not able to clearly declare readiness for organ procurement. What is more data analysis revealed certain gaps in more detailed knowledge and surprising attitudes. In that respect, the lack of awareness about the criteria for determining brain death could be mentioned. There was also a lack of acceptance for skin procurement in specific population groups. It can therefore be concluded that a key role in the success of the idea of transplantation in Poland is the broad and systematic education of the society

Own experience from the use of a substitute of an allogeneic acellular dermal matrix revitalized with in vitro cultured skin cells in clinical practice

As a result of the removal of cells from human allogeneic dermis, a collagen scaffold is obtained, which can be populated de novo with autologous/allogeneic skin cells and transplanted onto the area of skin loss. The optimal method for production of acellular dermal matrices (ADM) has been selected. Three female patients (a mean age of 54 years) were subjected to the transplantation of either autologous or allogeneic keratinocytes and fibroblasts into the holes of acellular dermal matrix (ADM) mesh graft. The method for burn wound treatment based on the use of a viable dermal-epidermal skin substitute (based on ADM and in vitro cultured fibroblasts and keratinocytes) may be the optimal method of burn treatment

Human Acellular Dermal Matrix in Reconstructive Surgery—A Review

Reconstructive surgery often confronts large tissue defects. This creates a need to look for materials that are immunogenic but offer the possibility of tissue filling. ADM—acellular dermal matrix—is a biological collagen matrix without immunogenicity, which is more commonly used in surgical treatment. Reconstructive surgery is still searching for various biocompatible materials that can be widely used in surgery. The available materials have their advantages and disadvantages. This paper is a literature review on the use of human acellular dermal matrix (ADM) in reconstructive surgery (surgical oncology, plastic and reconstructive surgery, and gynecologic reconstructive surgery). ADM appears to be a material of increasing use in various fields of surgery, and thus, further research in this area is required

Chitosan/aminoacid hydrogels with antimicrobial and bioactive properties as new scaffolds for human mesenchymal stem cells culture applicable in wound healing

Application of human mesenchymal stem cells brings a new hope for advanced wound healing. To enable cells culture and their viability maintenance, a new type of biomaterials must be developed. Scaffolds prepared from polymers of natural origin can mimic extracellular matrix. Chitosan, which is a chitin derivative, has many favorable properties like biodegradability or lack of cytotoxicity. Therefore, it is widely applied in medicine and pharmacy. Nevertheless, its chemical modification may lead to the loss of biocompatibility of the material and generate some significant problems with cells culture. In this article a novel strategy of the bioactive and antimicrobial chitosan hydrogel scaffolds is presented. As crosslinking agents non-toxic substances were used such as aspartic acid and glutamic acid. Obtained biomaterials were investigated over their chemical structure, morphology and biological activity. Performed tests using human mesenchymal stem cells confirmed bioactivity and biocompatibility, as well as antibacterial and antifungal properties.Web of Science12111210

Microwave-assisted synthesis and characterization of bioactive chitosan scaffolds doped with Au nanoparticles for mesenchymal stem cells culture

In this work we present a novel strategy for chitosan-based scaffolds. Chitosan is a versatile biopolymer obtained from waste biomass known of its favorable biological properties. Thus it can replace other polymers in the preparation of bioactive scaffolds. To increase its durability chitosan can be crosslinked into form of the hydrogel yet application of toxic crosslinkers may lead to loss of biocompability. Mesenchymal stem cells can be used in cell therapy for advanced wound treatment. However their culture requires special biomaterials application. In this article a novel microwave-assisted synthesis method for bioactive chitosan scaffolds is presented.Web of Science68735935
