Third-degree or full-thickness burns refer to lesions that extend to the epidermis, dermis, and subcutaneous tissue. The pathophysiology of burn wounds is characterized by tissue inflammation, edema, and hypertrophic scarring. Farnesol is a natural 15-carbon organic compound that possesses many biological effects. ⋯ On days 7 and 14 post wounding, histopathological observations revealed that the HPMC:farnesol gel ratios of 1:2 and 2:1 exerted the greatest tissue-repairing effects on the skin after third-degree burns compared with skin untreated or treated with a commercial burn gel and HPMC alone. These findings were consistent with the in vivo quantitative collagen-producing assay, wound healing scoring, and IL-6 Western blot results. These findings demonstrated that the fabricated liposomal farnesol gel is potentially able to promote wound healing after third-degree burns.

The occurrence of acute respiratory distress syndrome (ARDS) significantly increases the mortality and morbidity of major burns; there are few laboratory markers that predict the development of ARDS in severe burns. This study was to investigate the relationship between complete blood count (CBC) parameters and the incidence of ARDS in severe burn patients. ⋯ The findings of this study suggest that an elevated RDW is associated with an increased risk of ARDS and RDW is an independent risk factor in the prediction of ARDS after severe burns.

Paediatric population still represents a high burden of hospitalisations among burns inpatients. Children under five years old have a distinct aetiology distribution comparing to other age groups, representing in Portugal a fifth of all hospitalisations with burns. We aimed to describe the demographic and clinical burden of burns requiring hospitalization, as well as hospitalization charges, among this age group in Portugal. ⋯ This Portuguese nation-wide study on hospitalisations with burns highlights that 90% of all burns were due to hot liquid or object and a major impact of patients younger than 2years old in this age group. Urban vs rural difference in hospitalization rate should also be considered for further health inequalities' studies. As conclusion, ongoing attention needs to be dedicated to paediatric burn prevention and safety cost-effective strategies, particularly in relation to scalds, to further reduce the incidence of burn hospitalisations in children and the associated hospital costs.

Burns cause acute damage to the peripheral nervous system with published reports identifying that neurological changes after injury remain for a prolonged period. To shed some light on potential mechanisms, we assessed injury etiology and patterns of nervous system morbidity after injury by comparing long-term hospital admissions data of burns patients and other non-burn trauma patients with uninjured people. ⋯ Results suggest that injury patients are at increased risk of peripheral nervous system morbidity after discharge for a prolonged period of time. The time patterns associated with incident nervous system conditions suggest possible differences in underlying pathology and long-term patient care needs. Further research is needed to elucidate the underlying neuropathology.

Biofilm forms when bacteria surrounded by an extracellular matrix aggregate on a surface. It can develop on many surfaces, including wound dressings; this can be particularly nefarious for burn patients undergoing skin grafting (autograft) for burn wound coverage as they often suffer from compromised immune system function. Autograft donor sites are particularly vulnerable to biofilm formation; as such, timely healing of these sites is essential. ⋯ Samples of each wound dressing, which were in contact with the skin graft donor site, were prepared for analysis under the scanning electron microscope (SEM) using an original method developed by our research group that aims to maintain the integrity of the biofilm microstructure. Samples prepared by this method were then analyzed using SEM, which allowed the characterization of biofilm and the evaluation of bacterial density on the studied dressing samples. To this day, this imaging technique has been rarely employed for dressing analysis and this is the first time that it is employed for in situ biofilm visualization for this particular application.
