The aim of this study is to investigate the effects of parenteral glutamine(GLN) supplementation combined with enteral nutrition (EN) on heat shock protein 90(Hsp90) expression, apoptosis of lymphoid organs and circulating lymphocytes, immunological function and survival in severely burned rats. ⋯ The results of this study show that parenteral GLN supplementation combined with EN may increase the GLN concentrations of plasma and tissues, up-regulate the expression of Hsp90, attenuate apoptosis in lymphoid organ and circulating lymphocyte, enhance the immunological function and improve survival in severely burned rats. Clinically, therapeutic efforts at the modulation of the immune dysfunction may contribute to a favorable outcome in severely burned patients.

For more than 40 years, silver sulphadiazine 1% (SSD) is considered as standard therapy for the conservative treatment of burn wounds. However, in the last 10 years, substantial disadvantages of SSD have been reported in the literature and probably as a result of this, several new dressings for burn wounds have been developed and put on the market. The objective of this systematic review is to evaluate the available evidence on SSD in the conservative treatment of burns, specifically in comparison with the newer burn dressings that are increasingly being used nowadays. ⋯ The results of this systematic review clearly demonstrate that a faster wound healing is obtained with the newly developed burn dressings. Additionally, these new dressings tend to be more comfortable for the patients and easier to use for care givers. The minor differences in antibacterial activity between SSD and the new products did not seem to have any influence on the rate of wound healing. Since rapid wound closure is essential to obtain an optimal functional and aesthetic outcome, it can be concluded from the results of this systemic review that the standard use of SSD in the conservative treatment of burn wounds can no longer be supported.

Ear reconstruction remains a challenging procedure, especially in burn victims. The ear is particularly vulnerable to thermal injury because of its location and the thin integument. The thermal injury could subsequently include skin and the deeper located auricular cartilage framework. ⋯ Furthermore, 3D (bio)printing of cartilage to facilitate reproduction of the ear's complex shape certainly has potential and might find an interesting role in ear reconstruction. In this review, different clinical challenges and options for ear reconstruction in burn patients are described. Subsequently, although still far from large scale clinical application, state of the art developments in the field of tissue engineering and 3D (bio)printing are also discussed.
