The conventional surgical treatment (excision and skin autograft or flap) often fails to prevent unpredictable and un-controlled extension of the radiation necrotic process. We report here our second experience of therapeutic management of a radiation accident victim combining surgery and cellular therapy using autologous Mesenchymal Stem Cells (MSC). The patient presented a very severe arm radiation burn which was treated by several surgical times: iterative excisions, skin graft, latissimus muscle dorsi flap and forearm radial flap). Local autologous MSC were administrated as an adjuvant to improve the surgical approach. The clinical evolution (radiation pain and healing progression) was favourable and no recurrence of radiation inflammatory waves was observed during the eight month patient’s follow-up suggesting that MSC act as ”cell drug” in modulating radiation inflammatory processes. Thes...

A la phase aiguë, l'intubation doit être précoce en cas de lésions cutanées étendues ou d'inhalation de fumées. Chez le brûlé, le délai idéal entre l'intubation et la conversion en trachéotomie n'est pas clairement établi par les études cliniques. en réanimation, la trachéotomie percutanée devint la méthode de choix. La trachéotomie offre un bénéfice en terme de sécurité et d'efficacité de la ventilation. Toute technique s'accompagne de complications trachéales, en particulier en cas d'inhalation ou d'infection pulmonaire.

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. Methods: From 1991 to 1996, CEA were applied to a mean 37217% of total body surface area (TBSA) of 30 patients. These patients had 78210% average burn size, 65216% average third-degree burn size, 90% prevalence of endoscopically con®rmed inhalation injury and 37% prevalence of other serious conditions. Results: CEA achieved permanent coverage of a mean 26215% of TBSA, an area greater than that covered by conventional autografts (a mean 25 2 10% of TBSA). Survival was 90% in these severely burned and otherwise traumatized patients. Final CEA take was a mean 69 2 23%. In subset analyses, only younger age was signi®cantly associated with better CEA take p 0X0001 in univariate analysis, p < 0.04 in multivariate analysis, Student's t-test). Conclusions: Epicel CEA successfully provided extensive, permanent burn coverage in severely traumatized patients, proving an important adjunct to achievement of a high survival rate in a patient population whose prognosis previously had been poor. In our experience CEA appear to have a very high bene®cial value in the management of burns >60% TBSA. In some cases studied it is very likely that CEA was a life-saving treatment.

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 ␥-irradiated human skin biopsies were dissociated and fibroblasts were isolated and grown for several days. Cells next underwent PCC-FISH painting of whole chromosome 4, and the number of excess chromosome segments per metaphase was determined. An ex vivo reference curve correlating the number of excess chromosome segments per metaphase to the radiation dose was established and used to assess the dose delivered to the skin of one of the victims of the radiological accident that occurred at Lia in Georgia in December 2001. Specifically, the victim suffering from moist desquamation underwent skin excision in Hospital Percy (France). Measurement of excess chromosome segments per metaphase was done in fibroblasts isolated and grown from removed wounded skin and subsequent conversion to radiation doses was performed. The radiation dose map obtained was shown to be in accordance with clinical data and physical dosimetry as well as with conventional biodosimetry. These results demonstrated that PCC-FISH painting applied to skin fibroblasts may be a suitable technique for dose estimation. To assess its worth, this approach needs to be extended to future accidents involving localized radiation exposure.

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. 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). Studies were selected by a single reviewer. Overall, 99 studies met the selection criteria (89 randomized controlled trials [RCTs], 3 meta-analyses [1 of which came from 1 of the selected systematic reviews], 7 systematic reviews, and 1 cost-effectiveness study). The RCTs, meta-analyses, and cost-effectiveness studies were critically appraised by 2 reviewers to assess the clinical evidence level according to a modification of Sackett&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s 1989 criteria. Ninety-three articles were finally graded. We found no level A studies, 14 level B studies (11 RCTs and 3 meta-analyses), and 79 level C studies. Hydrocolloid dressings proved superior to saline gauze or paraffin gauze dressings for the complete healing of chronic wounds, and alginates were better than other modern dressings for debriding necrotic wounds. Hydrofiber and foam dressings, when compared with other traditional dressings or a silver-coated dressing, respectively, reduced time to healing of acute wounds. Our systematic review provided only weak levels of evidence on the clinical efficacy of modern dressings compared with saline or paraffin gauze in terms of healing, with the exception of hydrocolloids. There was no evidence that any of the modern dressings was better than another, or better than saline or paraffin gauze, in terms of general performance criteria. More wound care research providing level A evidence is needed.
