The technique of percutaneous screw fixation, with increasing popularity, has been successfully conducted in non-displaced, stable scaphoid fractures resulting in shortened immobilization duration and prompt functional retrieval. The purpose of this study was to evaluate the surgical technique and to explore the potential benefits of using percutaneous screw fixation in unstable scaphoid fractures. ⋯ The technique of percutaneous screw fixation was successfully used to treat 11 unstable scaphoid fractures. The encouraging outcome of this treatment option and the prompt functional recovery deserve further investigation. Further randomized prospective studies to explore the specific indications and ubiquitous benefits of the technique presented herein are recommended.

The current seroprevalence of human immunodeficiency virus (HIV), hepatitis B, and hepatitis C in the Canadian trauma population is unknown. Establishing the seroprevalence of these diseases is vital for education, postexposure prophylaxis, and counseling, and to establish potential screening guidelines. The purpose of this study was to determine the seroprevalence of HIV, hepatitis B, and hepatitis C in the trauma population of London, Ontario, Canada. ⋯ This is the first study to determine the rates of HIV, hepatitis B, and hepatitis C in the Canadian trauma population. Our trauma population demonstrated a threefold higher hepatitis C seroprevalence rate compared with the general population. Hepatitis C poses the highest risk to the trauma team of the three bloodborne diseases studied. With no vaccine or postexposure prophylaxis currently available for hepatitis C, this study highlights the importance of prevention and the strict use of universal precautions in the setting of trauma.

Pregnant women represent a major challenge in trauma care because of the risks to both mother and child and because of the difficulties in following standard protocols. ⋯ We suggest that normal lifestyle choices contribute to an increased risk of major trauma during pregnancy and merit greater awareness throughout the year.

Comparative Study
A salmon thrombin-fibrin bandage controls arterial bleeding in a swine aortotomy model.
Recently, a wide variety of bandages have been formulated to attempt to improve the effectiveness of emergency intervention in situations of uncontrolled bleeding. The best of these dressings contain a mixture of human thrombin and fibrinogen. The presence of human components in these bandages, although effective, increases the cost of the dressing and raises questions of availability of raw materials and transmission of pathogens. The purpose of this study was to investigate the efficacy of dressings composed of salmon thrombin and fibrinogen in a swine aortotomy model. ⋯ Fibrin dressing using salmon-derived thrombin and fibrinogen is effective in controlling severe, uncontrolled bleeding. This dressing may offer an alternative to dressings composed of human coagulation proteins.

The epidemiology and prognosis of fireworks-related injuries treated at a tertiary eye care center in less developed nations remain unknown. ⋯ Fireworks-related ocular injuries commonly affect young male subjects of northern India. Visual outcome is better in eyes having better initial BCVA or closed globe injury and if relative afferent pupillary defect, bottle rocket injury, intraocular foreign body, and endophthalmitis are absent.
