Alveolar IL-8 has been reported to early identify patients at-risk to develop ARDS. However, it remains unknown how alveolar IL-8 is related to pulmonary and systemic inflammation in patients predisposed for ARDS. We studied 24 patients 2-6h after multiple trauma. ⋯ L, 12% (3-73%) vs. 6% (2-32%), p = 0.1) but correlated significantly with BAL IL-8, IL-6 and IL-1ra. High-risk patients had increased plasma levels of pro- but not anti-inflammatory mediators. The enhanced alveolar and systemic inflammation associated with alveolar IL-8 release should be considered to identify high-risk patients for pulmonary complications after multiple trauma to adjust surgical and other treatment strategies to the individual risk profile.

Varying results have been reported concerning the effect of body mass index (BMI) on polytrauma outcome. Although most studies focus on obesity and its associated preexisting medical diseases as a predictor for increased mortality rates, there is evidence that polytrauma patients with underweight also face an inferior outcome. ⋯ There is a significant correlation between obesity, underweight, and increased mortality in polytraumatized patients. Efforts to promote optimal body weight may reduce not only the risk of chronic diseases but also the risk of polytrauma mortality amongst obese and underweight individuals.

Comparative Study
A 2-year experience, management and outcome of 200 clavicle fractures.
Clavicle fractures can cause pain and functional impairment if not managed appropriately. This article evaluates the prevalence of clavicular fractures, estimates the number of cases requiring operative treatment, evaluates whether removal of implant is a frequent necessity and compares the final functional outcome of the operative and non-operative groups. ⋯ The incidence of clavicle fractures was 1.23%. A small number of patients (11.7%) required operative treatment. We recommend surgical management of symptomatic non-union and removal of metal implant for hardware-related irritation.

Acutrak 2 screws are commonly used for scaphoid fracture fixation. To our knowledge, the variation in compressive force along the screw has not been investigated before. The objectives of our study were to measure variance in compression along the length of the standard Acutrak 2 screw, to identify the region of the screw which produces the greatest compression and to discuss the clinical relevance of this to the placement of the screw for scaphoid fractures. ⋯ There is variation in compression along the length of the standard Acutrak 2 screw and the maximum compression was obtained at the mid-point of the screw. From this study, we would recommend when using an Acutrak 2 screw for internal fixation of scaphoid fractures, to attain maximum compressive force, place the fracture at the mid-point of the Acutrak screw. If this is not possible, then place the fracture towards the proximal half of the screw.
