Efficacy and tolerability of a cocktail of bacteriophages to treat burn wounds infected by Pseudomonas aeruginosa (PhagoBurn): a randomised, controlled, double-blind phase 1/2 trial.

Background: Wound infections are the main cause of sepsis in patients with burns and increase burn-related morbidity and mortality. Bacteriophages, natural bacterial viruses, are being considered as an alternative therapy to treat infections caused by multidrug-resistant bacteria. We aimed to compare the efficacy and tolerability of a cocktail of lytic anti-Pseudomonas aeruginosa bacteriophages with standard of care for patients with burns.

Antibiotics and the burn patient.

Infection is a major problem in burn care and especially when it is due to bacteria with hospital-acquired multi-resistance to antibiotics. Moreover, when these bacteria are Gram-negative organisms, the most effective molecules are 20 years old and there is little hope of any new product available even in the distant future. Therefore, it is obvious that currently available antibiotics should not be misused.

Mass casualty incidents with multiple burn victims: rationale for a Swiss burn plan.

Introduction: Mass casualty incidents involving victims with severe burns pose difficult and unique problems for both rescue teams and hospitals. This paper presents an analysis of the published reports with the aim of proposing a rational model for burn rescue and hospital referral for Switzerland.

Methods: Literature review including systematic searches of PubMed/Medline, reference textbooks and journals as well as landmark articles.

Emerging therapy for improving wound repair of severe radiation burns using local bone marrow-derived stem cell administrations.

The therapeutic management of severe radiation burns remains a challenging issue today. Conventional surgical treatment including excision, skin autograft, or flap often fails to prevent unpredictable and uncontrolled extension of the radiation-induced necrotic process. In a recent very severe accidental radiation burn, we demonstrated the efficiency of a new therapeutic approach combining surgery and local cellular therapy using autologous mesenchymal stem cells (MSC), and we confirmed the crucial place of the dose assessment in this medical management.

[Treatment of radiation burns with surgery and cell therapy. A report of two cases].

Treatment of severe radiation burns remains a difficult challenge. Conventional surgical treatment (excision, skin grafting, skin or muscle flaps) often fails to prevent unpredictable and uncontrolled extension of the necrotic process. We report two clinical cases in which surgery was combined with mesenchymal stem cell (MSC) therapy.

Dressings for acute and chronic wounds: a systematic review.

Objective: To critically review the literature on the efficacy of modern dressings in healing chronic and acute wounds by secondary intention.

Data Sources: Search of 3 databases (MEDLINE, EMBASE, and the Cochrane Controlled Clinical Trials Register) from January 1990 to June 2006, completed by manual research, for articles in English and in French.

Study Selection: The end points for selecting studies were the rate of complete healing, time to complete healing, rate of change in wound area, and general performance criteria (eg, pain, ease of use, avoidance of wound trauma on dressing removal, ability to absorb and contain exudates).

New approach to radiation burn treatment by dosimetry-guided surgery combined with autologous mesenchymal stem cell therapy.

The therapeutic management of severe radiation burns remains a challenging issue. Conventional surgical treatment (excision and skin autograft or rotation flap) often fails to prevent unpredictable and uncontrolled extension of the radiation necrotic process. We report here an innovative therapeutic strategy applied to the victim of a radiation accident (December 15, 2005) with an iridium gammagraphy radioactive source (192Ir, 3.

Evaluation of serum procalcitonin concentration in the ICU following severe burn.

The goal of the study was to analyse plasma procalcitonin (PCT) concentrations during infectious events of burns in ICU. Clinical and laboratory data were collected at admission and twice a week in burned patients admitted with a total body surface area (TBSA) >20%. Procalcitonin was determined using both a semi-quantitative detection (PCT-Q) and a quantitative immunoluminometric method (PCT-Lumi).

Collapse of skin antioxidant status during the subacute period of cutaneous radiation syndrome: a case report.

This case report describes a patient suffering from accidental cutaneous radiation syndrome. Clinical symptoms were characterized by the presence of moist epidermal denudation over approximately 8% of the body surface without signs of necrosis 88 days after radiation exposure. The skin transcriptional profile was obtained and provides a comprehensive overview of the changes in gene expression associated with skin wound healing after irradiation.

[Heparin-induced thrombocytopenia: report of four cases in severely burned patients].

Heparin-induced thrombocytopenia (HIT) is a dangerous complication of heparin therapy caused by an antibody against heparin/Platelet Factor 4 (PF4) complex. HIT complicates about 2% of treatment with unfractionated heparin (UFH). The aim of the study was to determine the incidence of HIT in a burn center and to report four cases in severely burned patients.

[Respiratory dysfunction in burned patients].

Introduction: Smoke inhalation and respiratory complications are still the major causes of mortality in severely burned patients.

State Of The Art: The diagnosis is suspected clinically on the basis of history and physical examination and can be confirmed bronchoscopically. Respiratory failure in burned patients occurs through a number of associated mechanisms.

PCC-FISH in skin fibroblasts for local dose assessment: biodosimetric analysis of a victim of the Georgian radiological accident.

We propose a new method of biodosimetry that could be applied in cases of localized irradiation. The approach is based on excess chromosome segments determination by the PCC-FISH technique in fibroblasts isolated from skin biopsy. Typically, 0 to 10 Gy ex vivo gamma-irradiated human skin biopsies were dissociated and fibroblasts were isolated and grown for several days.

A silver sulphadiazine-impregnated lipidocolloid wound dressing to treat second-degree burns.

Objective: To evaluate the efficacy and tolerance of Urgotul SSD dressing (Laboratoires Urgo) in the treatment of second-degree burns.

Method: This was a national multicentre phase III non-comparative open-label prospective study involving 10 burns units. The 41 subjects were non-immunosuppressed adults with second-degree thermal burn(s), which were clinically non-infected, less than 24 hours old, had a surface area less than 500 cm2 and warranted the local use of silver sulphadiazine.

Urgotul: a novel non-adherent lipidocolloid dressing.

Urgotul belongs to a new class of non-adherent dressings: the lipidocolloid dressings. It is composed of an open weave polyester mesh impregnated with hydrocolloid polymers dispersed within petrolatum. The first clinical trial data are presented.

[Inflammatory reaction and infection in severe burns].

Major burn injury is a lesion where the inflammatory reaction is exported to the whole body. After a short time of hemodynamic changes, this inflammation is kept by necrotic tissues, persistence of an opened wound, and by the pulmonary and gut reactions. When infection starts, it becomes difficult to distinguish its symptoms among the inflammatory signals.

Long-term regeneration of human epidermis on third degree burns transplanted with autologous cultured epithelium grown on a fibrin matrix.

Background: Extensive third degree burn wounds can be permanently covered by the transplantation of autologous cultured keratinocytes. Many modifications to Green and colleagues' original technique have been suggested, including the use of a fibrin matrix. However, the properties of the cultured cells must be assessed using suitable criteria before a modified method of culture for therapeutic purposes is transferred to clinical use, because changes in culture conditions may reduce keratinocyte lifespan and result in the loss of the transplanted epithelium.

Ornithine alpha-ketoglutarate improves wound healing in severe burn patients: a prospective randomized double-blind trial versus isonitrogenous controls.

Objective: To compare the effectiveness on wound healing time in severe burn patients of ornithine alpha-ketoglutarate supplementation of enteral feeding vs. an isonitrogenous control. Previous clinical and experimental studies suggest a beneficial effect of enterally administered ornithine alpha-ketoglutarate supplementation on protein metabolism in burn patients, but few data deal with clinical outcome.

Cultured epithelial autografts in extensive burn coverage of severely traumatized patients: a five year single-center experience with 30 patients.

Objective: We report recent five-year experience in a large, single center series of severely burned and otherwise traumatized patients given cultured epithelial autografts (CEA) from a single commercial laboratory.

Summary Background Data: Initial optimism over CEA application has been tempered by subsequent reports asserting that this modality is unreliable and expensive. Discussion continues over its clinical role.

[Ambulatory treatment of burns in children].

A majority of burns in children may have an ambulatory management for which the paediatrician has an important role. He must assess the severity of the burn by quoting extent, depth and localization of the burn injuries and then send the most severe to a specialized burn centre. The circumstances and the social situation are important in the decision of either hospitalization or ambulatory care, remembering that the burn may correspond to child abuse.

[Pharmacokinetics of fusidic acid in patients with seriously infected burns].

The pharmacokinetics of fusidic acid (FA) were studied in 10 infected severe burns patients (35 +/- 5 yrs, 81 +/- 17 kg) i.e. 43 +/- 10% in 3rd degree.

Initial general management and surgery of six extensively burned children treated with cultured epidermal autografts.

Purpose: The aim of this study was to document the surgical and intensive care methods used in six extensively burned children (EBC), ie, total body surface area (TBSA) burned over 70% or TBSA with deep burns over 60%, treated with cultured epidermal autografts (CEA).

Methods: Six EBC, with a mean age of 7.5 years (range, 2.
