We modified our established and clinically relevant ARDS model of smoke inhalation injury and septic shock by administration of combined antibiotics (AB) such as piperacillin and ciprofloxacin, to more closely mimic the clinical intensive care setting. Twenty-three sheep were subjected to the injury, and allocated to four groups for a 96 h study period: sham (n=5 non-injured); control (n=6: injured); AB6h (n=6: injured, antibiotics started 6 h post-injury); AB12h (n=6: injured, antibiotics started 12 h post-injury). All sham animals survived 96 h. ⋯ Eighty three percent of AB6h and fifty percent of AB12h survived 96 h. Median survival times were significantly improved in the treated groups compared with the control group: 24 h in control vs. 80.5 h in AB6h, and 65 h in AB12h animals. Combined ciprofloxacin and piperacillin therapy was effective, reduced nitric oxide production and mortality, and will allow future long-term studies in this model.

To explore the epidemiology of childhood electrocution in Bangladesh, a population-based cross-sectional survey was conducted between January and December 2003. Nationally representative data was collected from 171,366 rural and urban households, comprising of a total population of 819,429. The average incidence rate of non-fatal childhood electrocution was 53.2 per 100,000 population-year. ⋯ Rural children are at higher risk compared to urban. Home is the most common place of childhood electrocution. A national strategy and prevention program is necessary to address morbidity and mortality of children due to electrocution.

Persistent and extensive skeletal muscle catabolism is characteristic of severe burns. Whole body protein metabolism, an important component of this process, has not been measured in burned children during the long-term convalescent period. The aim of this study was to measure whole body protein turnover in burned children at discharge (95% healed) and in healthy controls by a non-invasive stable isotope method. Nine burned children (7 boys, 2 girls; 54±14 (S.D.)% total body area burned; 13±4 years; 45±20 kg; 154±14 cm) and 12 healthy children (8 boys, 4 girls; 12±3 years; 54±16 kg; 150±22 cm) were studied. A single oral dose of (15)N-alanine (16 mg/kg) was given, and thereafter urine was collected for 34 h. Whole body protein flux was calculated from labeling of urinary urea nitrogen. Then, protein synthesis was calculated as protein flux minus excretion, and protein breakdown as flux minus intake. At discharge, total protein turnover was 4.53±0.65 (S.E.)g kg body weight(-1) day(-1) in the burned children compared to 3.20±0.22 g kg(-1) day(-1) in controls (P=0.02). Expressed relative to lean body mass (LBM), the rates were 6.12±0.94 vs. 4.60±0.36 g kg LBM(-1) day(-1) in burn vs. healthy (P=0.06). Total protein synthesis was also elevated in burned vs. healthy children, and a tendency for elevated protein breakdown was observed. ⋯ Total protein turnover is elevated in burned children at discharge compared to age-matched controls, possibly reflecting the continued stress response to severe burn. The oral (15)N-alanine bolus method is a convenient, non-invasive, and no-risk method for measurement of total body protein turnover.

Severe facial burns cause significant deformities that are technically challenging to treat. Conventional treatments almost always result in poor aesthetic and functional outcomes. This is due to the fact that current treatments cover or replace the delicate anatomical facial tissues with autologus grafts and flaps from remote sites. ⋯ The psychosocial and ethical issues associated with this new treatment have some nuances but generally have many similarities with solid organ and more recently hand transplantation, both of which have been performed clinically for 40 and 10+ years respectively. Herein, we will discuss the technical and immunological aspects of facial tissue transplantation. The psychosocial and ethical issues will be discussed separately in another article in this issue.

Randomized Controlled Trial
Hydroxyethylstarch supplementation in burn resuscitation--a prospective randomised controlled trial.
Hydroxyethylstarches (HES) are thought to be beneficial in trauma and major surgery management, due to their volume expansion and anti-inflammatory properties. This study examined the use of 6% (HES) in burn resuscitation. ⋯ Patients treated with HES-supplemented resuscitation required less fluid, showed less interstitial oedema and a dampened inflammatory response compared to patients receiving isotonic crystalloid alone.
