Brûlures chimiques: notre série sur 25 ans.

Chemical burns raise diagnostic and treatment issues because they have specific appearances and evolution. Our objective was to study the characteristics of chemical burns and to assess the quality of our treatment. This retrospective observational study examined the records of all patients admitted for chemical burns to the burn treatment center of Saint Louis Hospital in Paris from January 1, 1990, through December 31, 2015. During this period, 162 patients came to our center for chemical burn treatment. Most of them were men (67%). The majority of the burns were caused by alkalis (27%) and resulted from workplace accidents (29%). The average time before consultation was 5.36 days. The areas mainly damaged were the hands (36%) and the burn areas averaged 1.2% of the total body surface area (TBSA). Forty-eight patients had at least one deep patch. In total, 59 patients (36.4%) were hospitalized for an average duration of 4.18 days. Thirty-eight of them underwent surgery. Lastly, 92% of the operations had been anticipated from the first consultation. In our center, the population affected, the circumstances and the topography of our patients' burns were similar to the data from the literature. It appears that the principal specificity of our series is a very low body surface burned. This can be attributed to the prevention measures we have in France and underlines their importance. Only 8% of the patients who had surgery were underestimated or their burns became deeper secondarily. This number is lower than the data from other series.

Our 35 years' experience on postburn heterotopic ossification: A three-step treatment.

Our retrospective study of burn patients presents a three-step treatment of heterotopic ossification: excision surgery, early rehabilitation, and analgesia. We included patients admitted to the department for treatment of postburn heterotopic ossification between January 1, 1979, and September 30, 2015. The mean age at the time of the burn was 43.3 years. Men accounted for the majority of burn patients who developed an osteoma (70.8%). The mean total skin area burned was 38.4%. No osteoma justifying surgery was found for any patient with a total burned skin area less than 19%. The burned zones were related to the osteoma development in 94.3% of cases. On average, the surgery took place 10.8 months after the burn. The osteotomy was accompanied by surgical treatment of a contracture in 37.1% of patients. Most of the osteomata were found at the elbows (30), followed by the shoulders (3), and finally the knees (2). Rehabilitation began on D0 after the surgery, except if a flap or a thin-skin graft was used. Regarding analgesia, opiates were prescribed systematically during the immediate postoperative period. Elbow range of motion on flexion improved by a mean of 84.1°. During the postoperative period, we found 2 recurrences of osteoma and 1 elbow hematoma in two separate patients. There were no postoperative infections or neurological sequelae. Our retrospective French study confirmed results found in the international literature. The three-step treatment - excision surgery, early rehabilitation, and antalgia - seems to be the best means of treating osteoma with satisfactory results. Surgery is indicated only in the case of functional impairment and not simply based on imaging.

Burns caused by electronic vaping devices (e-cigarettes): A new classification proposal based on mechanisms.

Introduction With more than 10 million of daily users, e-cigarettes encountered a great success. But in the past few years, the number of medical reports of injuries caused by the explosion of e-cigarettes has significantly increased. This article aims at reporting our series and reviewing the literature to propose a new classification based on the mechanisms of injuries related to e-cigarettes that can guide non-specialists and specialists in the management of these patients. Method We performed a retrospective review of our institutional burn database from June 2016 to July 2017 for injuries caused by or in the context of using an e-cigarette. The patients' demographics (age, gender), burn injury mechanisms, depth, localization, surface and interventions were described. Results Ten patients suffered from burns related to the use of e-cigarettes. The burns were located at the thigh (80%) and the hand (50%) with a mean surface of 3% of TBSA. Four different mechanisms could be described: Type A: thermal burns with flames due to the phenomenon of "thermal runaway", Type B: blasts lesions secondary to the explosion, Type C: chemical alkali burns caused by spreading of the electrolyte solution and Type D: thermal burns without flames due to overheating. These different mechanisms suggest specific surgical and non-surgical management. Conclusion Management of injuries sustained from e-cigarettes' explosions should be approached from the standpoint of mechanisms. Different mechanisms could be associated and should be considered in specific management.

Dealing with tattoos in plastic surgery. Tattoo removal.

Not only has tattooing been socially performed for thousands of years, but it has also been part and parcel of medical practice since antiquity. In our day and age, plastic surgeons are ever more frequently compelled to deal with tattooing - and with tattoo removal procedures, as well. While the process itself may appear harmless, it is not without risk and necessitates use of suitable tools and management by expert hands.

Dealing with tattoos in plastic surgery. Complications and medical use.

Not only has tattooing been socially performed for thousands of years, but it has also been part and parcel of medical practice since antiquity. In our day and age, plastic surgeons are ever more frequently compelled to deal with tattooing, whether in terms of its medical application or its complications. While the process itself may appear harmless, it is not without risk and necessitates use of suitable tools and management by expert hands.
