The authors report the case of a patient presenting with an acute extradural hematoma and diffuse axonal injury. Control CT scan performed 4 hours later showed the complete resolution of the extradural collection together with increased evidence of shearing injuries. The mechanism of the hematoma resolution may probably be related to the concomitant acute brain swelling.

Randomized Controlled Trial Comparative Study Clinical Trial
Hypertonic saline fluid therapy following surgery: a prospective study.
Successful resuscitation of the injured may be achieved more rapidly and with less fluid using hypertonic crystalloid solutions than with isotonic solutions. This randomized, double-blind study compared 0.9% normal saline (NS) to 1.8% hypertonic saline (HS) in 20 postoperative coronary artery bypass patients suffering uniform injury. Study solutions were administered to maintain physiologic endpoints: heart rate, blood pressure, and pulmonary capillary wedge pressure. ⋯ No deaths occurred and no complication was attributed the hypertonicity of the solution. We conclude that 1.8% hypertonic saline is a safe alternative to isotonic crystalloid therapy in the fluid management of postoperative patients. Decreased third-space losses may occur with HS as suggested by the lower thoracic losses in the HS group; 1.8% NaCl may be the preferred solution in situations where excess free water administration is not desired, and where interstitial edema is detrimental to function and/or survival.

Review Case Reports
Blunt chest trauma with transection of the azygos vein: case report.
A review of the world literature revealed only five reported cases of azygos vein disruption from blunt chest trauma. Four of these were isolated injuries. ⋯ Emergency thoracotomy and venous ligation resulted in successful resuscitation. Shearing forces as a result of deceleration were felt to be a possible etiology.

A subluxation of an unstable cervical spine injury occurring during swimmer's positioning is described. Based on this experience, it is recommended that the initial radiographs be obtained and reviewed without traction or swimmer's positioning. With clinical or radiographic evidence of cervical injury, bilateral oblique views, plain lateral tomography, or computerized axial tomography may be required to evaluate the C7-T1 junction.
