One of the trauma surgeons' daily challenges is the balancing act between negative laparotomy and missed abdominal injury. We opted to characterize the indications that prompted a negative trauma exploratory laparotomy and the rate of missed abdominal injuries in an effort to optimize patient selection for laparotomy. At the Los Angeles County + University of Southern California Medical Center, negative laparotomies and missed injuries are consecutively captured and reviewed at the weekly mortality + morbidity (MM) conferences. All written reports of the MM meetings from January 2003 to December 2008 were reviewed to identify all patients who underwent a negative laparotomy or a laparotomy as a result of an initially missed abdominal injury. Over the 6-year study period, a total of 1871 laparotomies were performed, of which 73 (3.9%) were negative. The rate of missed injuries requiring subsequent laparotomy was 1.3 per cent (25 of 1871). The negative laparotomy rate and the rate of missed injuries did not vary significantly during the study period (2.8 to 4.7%, P = 0.875, and 0.7 to 2.9%, P = 0.689). Penetrating mechanisms accounted for the majority of negative laparotomies (58.9%). The primary indication for negative laparotomy was peritonitis (54.8%) followed by hypotension (28.8%) and suspicious computed tomographic scan findings (27.4%). The complication rate after negative laparotomy was 14.5 per cent, and of these, 10.1 per cent were directly related to the procedure. A low but steady rate of negative laparotomies and missed abdominal injuries after trauma remains. Negative laparotomies and missed abdominal injuries when they occur are still associated with significant complication rates and a prolonged length of stay.

The predictive factors to regain a heartbeat following emergency department resuscitative thoracotomy (EDT) for trauma are poorly understood. The objective of the present study was to prospectively assess the electrolyte profile, coagulation parameters, and acid-base status from intracardiac blood samples in trauma patients subjected to open cardiopulmonary resuscitation (CPR) in the presence of established cardiac arrest.

The objective of our study was to compare the performance of low-dose linear slit digital radiography (DR) with computed radiography (CR) for the detection of trauma sequelae in the chest including rib fractures, pneumothorax, and lung contusion.

Traumatic brain injury is one of the most common reasons for admission to hospital emergency departments. However, optimal diagnosis and treatment protocols remain controversial. The aim of this study is to assess whether a specific group of patients can be discharged from the hospital without 24-h neurological observation.

The purpose of the present retrospective study was to evaluate the post-traumatic healing of the pulp and periodontium of 32 permanent teeth with horizontal root fractures. Twenty-nine patients, 8-48 years old, who presented at our department with a root fracture between January 2001 and April 2007, participated in the study. Root-fractured teeth with a loosened or dislocated coronal fragment were repositioned and splinted for 14-49 days (average: 34 days). In cases of severe dislocation of the coronal fragment, prophylactic endodontic treatment was performed. Follow-up examinations were conducted routinely after 1,2,3,6, and 12 months. For this study, follow-up took place for up to 7 years post trauma. Of 32 root-fractured teeth, 29 (91%) survived. 10 teeth (31%) exhibited pulpal healing; 13 teeth (41%) were prophylactically endodontically treated within 2 weeks of injury. At the fracture line, interposition of calcified tissue was evident in 6 teeth (19%), and interposition of granulation tissue was observed in 8 teeth (25%). The prognosis of the root-fractured teeth was good, and one-third of the teeth with root fractures possessed a vital pulp at the final examination.

Many guidelines exist on how to treat patients with multiple injuries correctly in an accident and emergency setting. The aim of the present work was to find out how well patients are treated focusing on trauma induced coagulopathy (TIC), and what anaesthetists involved in trauma care think about their own experiences with TIC.

Posttraumatic stress disorder (PTSD) and circulating cellular adhesion molecules (CAMs) predict cardiovascular risk. We hypothesized a positive relationship between PTSD caused by myocardial infarction (MI) and soluble CAMs. We enrolled 22 post-MI patients with interviewer-rated PTSD and 22 post-MI patients with no PTSD. At 32±6months after index MI, all patients were re-scheduled to undergo the Clinician-Administered PTSD Scale (CAPS) interview and had blood collected to assess soluble CAMs at rest and after the CAPS interview. Relative to patients with no PTSD, those with PTSD had significantly higher levels of soluble vascular cellular adhesion molecule (sVCAM)-1 and intercellular adhesion molecule (sICAM)-1 at rest and, controlling for resting CAM levels, significantly higher sVCAM-1 and sICAM-1 after the interview. Greater severity of PTSD predicted significantly higher resting levels of sVCAM-1 and soluble P-selectin in patients with PTSD. At follow-up, patients with persistent PTSD (n=15) and those who had remitted (n=7) did not significantly differ in CAM levels at rest and after the interview; however, both these groups had significantly higher sVCAM-1 and sICAM-1 at rest and also after the interview compared to patients with no PTSD. Elevated levels of circulating CAMs might help explain the psychophysiologic link of PTSD with cardiovascular risk.

Hypercoagulability of the blood might partially explain the increased cardiovascular disease risk in posttraumatic stress disorder (PTSD) and is also triggered by anticipatory stress. We hypothesized exaggerated procoagulant reactivity in patients with PTSD in response to a trauma-specific interview that would be moderated by momentary stress levels. We examined 23 patients with interviewer-diagnosed PTSD caused by myocardial infarction (MI) and 21 post-MI patients without PTSD. A second diagnostic (i.e., trauma-specific) interview to assess posttraumatic stress severity was performed after a median follow-up of 26 months (range 12-36). Before that interview patients rated levels of momentary stress (Likert scale 0-10) and had blood collected before and after the interview. The interaction between PTSD diagnostic status at study entry and level of momentary stress before the follow-up interview predicted reactivity of fibrinogen (P=0.036) and d-dimer (P=0.002) to the PTSD interview. Among patients with high momentary stress levels, PTSD patients had greater fibrinogen (P=0.023) and d-dimer (P=0.035) reactivity than non-PTSD patients. Among patients with low momentary stress levels, PTSD patients had less d-dimer reactivity than non-PTSD patients (P=0.024); fibrinogen reactivity did not significantly differ between groups. Momentary stress levels, but not severity of posttraumatic stress, correlated with d-dimer reactivity in PTSD patients (r=0.46, P=0.029). We conclude that momentary stress levels moderated the relationship between PTSD and procoagulant reactivity to a trauma-specific interview. Procoagulant reactivity in post-MI patients with PTSD confronted with their traumatically experienced MI was observed if patients perceived high levels of momentary stress before the interview.

High prevalence of trauma has been reported in psychosis. While role of trauma as a risk factor for developing psychosis is still debated, its negative impact on outcome has been described. Few studies have explored this issue in first-episode psychosis (FEP) patients. We assessed rate of stressful events, as well as premorbid and outcome correlates of past sexual and/or physical abuse (SPA) in an epidemiological FEP patients cohort.
