Patients with diabetes mellitus may be at increased risk of accidents, mainly because of hypoglycemia. A variety of approaches have been adopted in an attempt to quantify this risk, but there has not been, to date, a systematic study using a national trauma register. In this study, we report findings from the Scottish Trauma Audit Group database. ⋯ This study confirms that patients taking insulin are at increased risk of accidents. Among the different types of injury, only low-impact falls were significantly increased. This is most likely related to an increased tendency for insulin-treated patients to fall during a hypoglycemic episode. However, patients with diabetes may also be at higher risk of sustaining a fracture after a fall. The number of car crashes involving drivers with insulin-dependent diabetes is small, and the rate is not significantly greater than that of the background population. Further study of the causes and consequences of falls in diabetic patients is warranted.

Experimental studies have shown that hemorrhagic shock is associated with the expression of inducible heat proteins, especially heat shock protein (Hsp) 72, in liver, brain, heart, and kidney. Moreover, induction of Hsp 72 by various stressors before the onset of shock has been associated with the attenuation of organ injury caused by hemorrhage. However, it is not known whether Hsp 72 is expressed after severe trauma in humans. The purpose of this study was therefore to determine whether Hsp 72 could be detected in the serum of patients early after severe trauma and whether serum levels of Hsp 72 might correlate with survival of trauma patients or the severity of the postinjury inflammatory response. ⋯ Hsp 72 can be detected in the serum of severely traumatized patients within 30 minutes after injury. Elevated initial serum levels of Hsp 72 (serum levels > 15 ng/mL) are associated with survival after severe trauma, but are not related to the incidence or severity of the postinjury inflammatory response or organ dysfunction.

Factors thought to influence the decision for limb salvage include injury severity, physiologic reserve of the patient, and characteristics of the patient and their support system. ⋯ Soft tissue injury severity has the greatest impact on decision making regarding limb salvage versus amputation.

The purpose of this report is to analyze the clinical presentation, diagnosis, and outcome of surgical treatment in patients with popliteal arteriovenous fistulas (AVFs) in order to make trauma surgeons aware of the various issues patients with popliteal AVFs might present. ⋯ Trauma of the popliteal space requires special attention, since blood vessel injuries in that zone might result in serious complications. Popliteal traumatic AVFs result in a high rate of leg amputation and long-standing fistulas produce cardiac overload. The presence of thrill and bruit over the injury site should alert the examiner to consider the existence of AVF. Angiography is a reliable diagnostic tool, and should be used in all vitally stable patients. Surgical or nonsurgical closure of AVF will prevent local and systemic complications that might be irreversible in long-standing fistulas.

In a statistical outcome analysis covering 10 years, 554 patients with isolated head trauma were analyzed. The aim of this study was to combine clinical and computed tomographic characteristics in a prognostic scoring system determining outcome after head injury. ⋯ The presented scaling system allows a predictive value in mortality and morbidity to be determined for each patient suffering from brain trauma.
