Burn injuries are unique in comparison to other types of trauma because of their severity and major systemic impact produced by extensive lesions with disfunctions that can persist even several years after the injury. Multiple complications can occur during burn injury evolution, from which infections are the most severe and the most frequently encountered, requiring adequate diagnosis and treatment. In most burn centers, increased mortality rates associate with severe burn injuries aggravated by the development of sepsis. There are multiple sources of infections in burned patients: lungs, wounds, catheters, gastrointestinal and urinary tract. Pathogens are often multi-resistant bacteria but also fungi and viruses appear as opportunistic infections. The main goal is represented by prevention of organ dysfunction development through specific supportive measures that avoid its onset. Early excision of the burn eschar and wound grafting is essential for patient outcome, decreasing duration of hospitalization, infectious risk and mortality. As a principle, antibiotic treatment in burn infectious complications is started empirically, with broad spectrum agents if the results of microbiological cultures are not available and immediately after the antibiogram is available, targeted antibiotic is introduced. De-escalation strategy is promoted in order to prevent antimicrobial resistance: narrow spectrum drugs with proven efficacy on determined germs are administered, avoiding if possible, reserve antibiotics.
Nasal reconstruction is challenging, considering surgical techniques complexity and difficulties in remodelling a tridimensional structure. Reconstructive requirements are: correct deformity evaluation, selecting the most suitable treatment option, respecting the principle of aesthetic subunit, appropriate reconstruction of each affected nasal layer, long-term stabile functional and aesthetic results. Reconstructive procedures range from simple to very complex. Conventional techniques can fail in restoring a satisfactory appearance in severely disfigured patients, for whom a new possibility arises: Vascularized Composite Allografts (VCA) transplantation. In this paper, we focus on nasal skeletal framework restoration. Structural defects may require a large amount of reconstructive material obtained usually from cartilage or bone autografts. Autologous cartilage is the gold standard in nasal architectural recovery, but in some cases, autologous graft sources are not available, imposing the necessity to use alternative solutions represented by the allografts or alloplastic materials. We analysed the specific features of skeletal allografts used in nasal reconstruction. With current clinical experience, the use of cartilage and bone allografts (especially irradiated cartilage homografts) shows a promising reconstructive option for nasal structural defects. For extensive facial defects, including midface deformities, impossible to restore with traditional surgical techniques, a new reconstructive era was open through the development of the VCA field.
Purpose: This study aimed to characterize the injuries involving periorbital region in our severely burned patients. Method: A 2 years retrospective study was conducted with a total of 210 severe burns admissions. Periorbital burn injuries (all produced in association with facial injuries) were encountered in 126 patients, representing the study group that was further analyzed for multiple parameters: demographics, mechanism of injury, TBSA (total body surface area), burn depth, inhalation injury, need for intubation and mechanical ventilation. The presence and severity of ocular injuries were also evaluated. Results: Analyzing our study group (n=126), we observed the presence of multiple negative prognosis factors: elderly patients, extensive burns, deep burns affecting functional areas, unfavorable mechanism (electric, chemical or explosions), inhalation injuries, need for intubation and mechanical ventilation, leading to severe morbidity and high mortality level. Ocular injuries were encountered in 37 patients (30 primary and 7 secondary lesions). The predominance of primary ocular lesions is explained trough high severity burns encountered in our patients with high mortality and lack of long-term clinical observations. Conclusion: The clinical outcome for periorbital burn injuries depends on patient characteristics, etiology, burn extension and depth, associated lesions, infectious risk and the quality of the treatment applied. Presence of ocular injuries in various severity degrees impose an adequate evaluation and specialized treatment, being associated with important morbidity. In severely burned patients, it is mandatory to apply preventive measures to avoid ocular complications. If exposure keratopathy is detected, prompt ophthalmologic treatment is essential to avoid functional impairment including loss of vision.

Severe burn injuries represent a major challenge to the entire healthcare system in developing countries and even for states with a high standard of care. A clear understanding of the physiopathology of burn injuries is essential for providing an adequate prompt treatment to ensure an optimal patient outcome. Early recognition and treatment of burns complications, especially severe infections represent an important prevention strategy, improving survival after these severe injuries. Specific treatment must be conducted according to the characteristics of the patients in order to reduce morbidity and mortality and avoid the development of antimicrobial resistance. A diagnostic and therapeutic algorithm is presented, centered on infectious source prevention and control with early surgical excision and skin grafting together with culture-guided antimicrobial therapy. It is a known fact that, indifferent of the involved germ, the best intervention for both prophylaxis and treatment of infections in the burn patient is the early excision of the devitalized tissue and subsequent closure of burn wounds with skin grafts, measures that diminish local and systemic mediator releasing effects in burnt tissue, attenuating the progressive inflammatory
