Comparative StudySurgical management of acute odontoid fractures: surgery-related complications and long-term outcomes in a consecutive series of 97 patients.
The purpose of this study was to determine the incidence of surgery for odontoid fractures and to study surgical mortality, surgical morbidity, and long-term outcome in a large, contemporary, consecutive, single-institution, surgical series of odontoid fractures. ⋯ The annual incidence of open fixation of odontoid fractures was 0.45 per 100,000 inhabitants, and the incidence increased with age. The median age at time of surgery was 73.0 years, and the surgical mortality was 4%. Increased odds of nonbony fusion were observed in more displaced fractures and after anterior screw fixations. There were no significant differences between patients treated with anterior screw fixation versus posterior wiring with respect to neck pain, but patients fused with a posterior approach reported significantly more neck stiffness.

Comparative StudyLessons learned from airway pressure release ventilation.
The aim of this article is to review a single institution's experience with airway pressure release ventilation (APRV) with respect to safety, complications, and efficacy at correcting hypercarbia and hypoxemia. ⋯ III.

Comparative StudyThe use of temporary abdominal closure in low-risk trauma patients: helpful or harmful?
Temporary abdominal closure (TAC) has become a widely used technique in severely injured patients. However, there is growing concern that TAC is being overutilized. We sought to identify less severely injured patients who underwent TAC and to compare their outcomes with patients managed with a single-stage laparotomy (SSL). ⋯ : III, therapeutic study.

Comparative StudyA questionable association of stroke volume and arterial pulse pressure under gravitational stress.
The purpose of this study was to examine individual stroke volume-pulse pressure (PP) relationships in healthy young men and women. ⋯ This work highlights the limitations of using PP when assessing trauma patients because of large interindividual differences.

Comparative StudyTargeting the lateral but not the third ventricle induces bone loss in ewe: an experimental approach to generate an improved large animal model of osteoporosis.
Osteoporosis is a chronic disease characterized by bone loss and increased skeletal fragility. Large animal models are required for preclinical testing of new therapeutic approaches. We have recently demonstrated that continuous intracerebroventricular (ICV) application of leptin into the lateral ventricle (LV) induces bone loss in ewe. On the basis of these findings, we reasoned that the third ventricle (TV) is an even better target because of its closer location to the hypothalamus that mediates leptin effects on bone. ⋯ ICV application of leptin into the LV strongly reduces bone formation and leads to a highly significant trabecular bone loss in ewe. In contrast, ICV application of leptin into the TV is technically more demanding and results are unpredictable, because the required use of stainless steel cannula induces peri-implant fibrosis that might prevent leptin to enter the cerebrospinal fluid.
