Comparative Study
Snowboard head injury: prospective study in Chino, Nagano, for two seasons from 1995 to 1997.
The popularity of snowboarding has been growing rapidly throughout the world. To date, however, the risk of head injury associated with this relatively new winter sport, especially in comparison with alpine skiing, has not been well analyzed. This study was conducted to assess the risk of head injury in snowboarding and to elucidate its features in comparison with skiing head injury. ⋯ These results indicate that snowboarders, particularly beginners, are at higher risk for head injury, frequently involving occipital impact, and could lead to more major head injuries. We propose that measures should be taken to protect the head, especially the occiput, in snowboarding.

An accurate assessment of deep dermal burns within the first week after burn is still an unresolved clinical problem. Infrared-excited fluorescence of indocyanine green was examined as a method of early determination of burn depth. ⋯ Deep partial-thickness burns were differentiated from deep dermal full-thickness burns in a porcine skin burn model independent of body location. Diagnosis was possible between 1 and 72 hours after injury.

Reconstructive microsurgery has been part of the treatment for severe tibial fractures for over 20 years. ⋯ In the past 5 years, the flap survival rate and the microvascular free flap operation methods were the same as they were in the 1980s, but the methods for enhancing the fracture union or reconstructing the bone defect has changed.

Randomized Controlled Trial Comparative Study Clinical Trial
Combat trauma airway management: endotracheal intubation versus laryngeal mask airway versus combitube use by Navy SEAL and Reconnaissance combat corpsmen.
Airway management takes precedence regardless of what type of life support is taking place. The gold standard for airway control and ventilation in the hands of the experienced paramedic remains unarguably the endotracheal tube. Unfortunately, laryngoscopy and endotracheal intubation require a skilled provider who performs this procedure on a frequent basis. Special Operations corpsmen and medics receive training in the use of the endotracheal tube, but they use it infrequently. The use of alternative airways by Navy SEAL and Reconnaissance combat corpsmen has not been evaluated. Our objective was to compare the ability of Special Operations corpsmen to use the endotracheal tube (ETT), laryngeal mask airway (LMA), and esophageal-tracheal combitube (ETC) under combat conditions. ⋯ The Special Operations corpsmen easily learned how to use the ETC and LMA. In this study, they showed the ability to appropriately use the ETT as well as the ETC and LMA. For SEAL corpsmen, the alternative airways should not replace the ETT; however, on occasion an advanced combat casualty care provider may not be able to use the laryngoscope or may be unable to place the ETT. The LMA and ETC are useful alternatives in this situation. If none of these airways are feasible, cricothyrotomy remains an option. Regardless of the airway device, refresher training must take place frequently.

We conducted a prospective study in patients with multiple injuries investigating the time course of trauma-related changes of systemic immunologic defense mechanisms. ⋯ In patients who died of severe trauma and in whom the cause of death was multiple organ failure, a significantly lower production of antiendotoxin antibodies was measured shortly before death. An insufficient immune defense (dysergy) may be involved in the pathomechanisms leading to the development of organ dysfunction.
