Blunt abdominal trauma resulting in gallbladder injury: a review with emphasis on pediatrics.
Gallbladder injury in blunt abdominal trauma is a rare and difficult diagnosis. Gallbladder injury is reported to be between 1.9% and 2.1% of all abdominal traumas. It has vague symptoms usually with inconclusive investigation results; hence, it is often diagnosed at laparotomy. The patient typically has vague abdominal pain and occasionally a period of remission depending on the type of gallbladder injury. In pediatrics, blunt abdominal trauma presents additional challenges of difficult historians and compensating physiology. Any delay in diagnosis and definitive management will worsen the prognosis. Making the diagnosis requires astute clinical acumen and radiologic interpretation. The classification system of Losanoff has merit in guiding treatment. While cholecystectomy is the preferred treatment, there are occasions when the gallbladder may be left in situ and these are discussed. ⋯ The authors highlight the incidence of associated visceral injuries in gallbladder trauma (>90%). Gallbladder perforation is more likely in cases when the gallbladder is distended and thin-walled at the time of injury. Therefore, we recommend that gallbladder perforation is suspected in those patients who have drunk alcohol or eaten recently. Despite the developments in modern computed tomography, identifying gallbladder perforation is difficult because of the subtlety and rarity of the condition. We draw attention to the proposed anatomic classification systems because they are of some use in guiding treatment. In the absence of a diagnosis after blunt abdominal trauma and with intra-abdominal free fluid, the clinician faces the difficult decision of whether surgery is indicated for a potential visceral injury. After discussing the available evidence, the authors advocate a low index of suspicion for performing diagnostic laparoscopy.

Comparative Study
Does hypoxia affect intensive care unit delirium or long-term cognitive impairment after multiple trauma without intracranial hemorrhage?
Within the traumatic brain injury population, outcomes are affected by hypoxic events in the early injury period. Previous work shows a high prevalence of cognitive deficits in patients with multiple injuries who do not have intracranial hemorrhage identified on admission head computed tomography scan. We hypothesize that intensive care unit (ICU) delirium and long-term cognitive impairment (LTCI) are more likely in patients who have a hypoxic event within the first 48 hours of ICU admission. ⋯ Hypoxic events in the ICU do not have a direct correlation with ICU delirium or LTCI in the patients with multiple injuries without evidence of intracranial hemorrhage.

Multicenter Study Comparative Study
Unstable cervical spine fracture after penetrating neck injury: a rare entity in an analysis of 1,069 patients.
The value of cervical spine immobilization after penetrating trauma to the neck is the subject of lively debate. The purpose of this study was to review the epidemiology of unstable cervical spine injuries (CSI) after penetrating neck trauma in a large cohort of patients. ⋯ The overall incidence of unstable CSI after penetrating trauma to the neck is exceedingly low at 0.4%. Following GSW to the neck, an unstable CSI was noted in <1% of patients. After cervical SW, however, no spinal instability was noted precluding the need for spinal precautions in these instances.
