Pharmacologic thromboprophylaxis (PTP) may exacerbate intracranial hemorrhage (ICH) in patients with traumatic brain injury (TBI). We examined risk factors for hemorrhage progression in patients with blunt TBI and hypothesized that PTP would increase ICH progression in a subset of these patients. ⋯ These findings suggest that PTP use is associated with a 13-fold increased odds of further hemorrhage progression in patients whose F/U CT within 1 day of admission showed ICH progression; 16% of this risk can be attributed to receiving PTP. Conversely, PTP may be safe in a subgroup of patients with TBI with no ICH progression on initial F/U CT.

Comparative Study
Improved trauma system multicasualty incident response: comparison of two train crash disasters.
Two train crash multicasualty incidents (MCI) occurred in 2005 and 2008 in Los Angeles. A postcrash analysis of the first MCI determined that most victims went to local community hospitals (CHs) with underutilization of trauma centers (TCs), resulting in changes to our disaster plan. To determine whether our trauma system MCI response improved, we analyzed the distribution of patients from the scene to TCs and CHs in the two MCIs. ⋯ A trauma system performance improvement program allowed us to significantly improve our response to MCIs with improved utilization of TCs and improved distribution of victims according to injury severity and needs.

Since 1999, the Italian guidelines have been used at our department for the management of patients with mild head injury (MHI). According to these guidelines, a computed tomography (CT) scan should be obtained in all patients with coagulopathy and these should routinely undergo strict observation during the first 24 hours after injury; in addition they should have a control CT scan before discharge. With the increased use of anticoagulant therapy in the elderly population, admitting patients in such treatment with a MHI to the emergency rooms has become very common. The aim of our study was to evaluate the need of performing a control CT scan in patients on anticoagulation treatment who showed neither intracranial pathology on the first CT-scan nor neurologic worsening during the observation period. ⋯ According with our data, patients on anticoagulation treatment suffering from MHI could be managed with strict neurologic observation without routinely performing a control CT scan that can be reserved for the rare patients showing new clinical symptoms.

Despite the good and reliable results of the dynamic hip screw (DHS) for stable fracture patterns, complications of excessive sliding of the lag screw and inadequate bone anchorage occur frequently in elderly patients with unstable intertrochanteric fractures. Although polymethylmethacrylate (PMMA) bone cement has been widely used as a secondary fixation to facilitate fixation stability, there has been no prospective study on the clinical significance of PMMA cement to prevent these two complications in unstable fracture patterns. ⋯ With the meticulous augmentation technique demonstrated in this study, the PMMA cemented DHS proved to have better outcome than a conventional DHS for unstable intertrochanteric fractures in elderly patients. Typical complications related to a conventional DHS device for the treatment of such fractures were successfully prevented.

Although a lateral starting point for tibial nailing is recommended to avoid valgus misalignment, higher rates of intra-articular damage were described compared with a medial parapatellar approach. The aim of this anatomic study was to evaluate the fracture level allowing for a safe medial nail entry point without misalignment or dislocation of fragments. ⋯ According to the results of this study, a medial parapatellar approach can be performed without misalignment and fragment dislocation in proximal tibia fractures extending 8 cm or more below the tibial tuberosity.
