Comparative Study
Differential profile of facial injuries among mountainbikers compared with bicyclists.
Bicyclists and mountainbikers are prone to facial trauma. In the current study, we present a large series of cycling-related sports trauma to the face in an effort to identify the injury pattern among mountainbikers compared with bicyclists. ⋯ Appropriate design of helmets with faceguards will reduce the incidence of facial injuries caused by cycling-related accidents and incentives are needed for making helmet use compulsory for all cyclists, particularly for mountainbikers.

Bomb blast survivors occasionally suffer from profound shock and hypoxemia without signs of external injury. We hypothesize that a vagally mediated reflex such as the pulmonary defensive reflex is the cause of shock from blast wave injury. This study was a prospectively randomized, controlled animal study. ⋯ Our data implicate a vagally mediated reflex such as the pulmonary defensive reflex as the cause of shock seen immediately after a blast pressure wave injury.

Major inherent risks associated with percutaneous dilatational tracheostomy include loss of airway during endotracheal tube manipulation, inability to cannulate the trachea below the endotracheal tube, and difficulties related to neck anatomy. ⋯ This technique provides improved safety from loss of airway and illuminates the need for concomitant bronchoscopy.

Flap reconstruction around the ankle and heel is a technically demanding procedure. Some patients have contraindications for microsurgery, however, limiting the options for local tissue transfer. In this study, we describe our experience with a new flap technique for ankle and heel coverage. ⋯ This report demonstrates that our design of this modified wide-base reverse sural flap is suitable for flap reconstruction around the ankle and heel; especially for patients who have difficulty in receiving microsurgery. The surgical procedure is simple, and the results are satisfactory.

These studies address the question of the relative roles of humoral and neural pathways in the genesis and control of the fever component of the acute phase response. ⋯ Fever development for animals receiving LPS in experiment 1 demonstrates a temporal relationship -- with increments in plasma levels of LPS and pyrogenic cytokines obtained in experiment 2 after administration of LPS either i.p. or i.v. Vagotomy had no discernible effect on the responses regardless of the route of administration of LPS.
