Increased intracranial pressure is suspected in the pathogenesis of acute mountain sickness (AMS), but no studies have correlated it with the presence or severity of AMS. We sought to determine whether increased optic nerve sheath diameter, a surrogate measure of intracranial pressure, is associated with the presence and severity of AMS. We performed a(More)
BACKGROUND The epidemiology of acute pancreatitis in the United States is largely unknown, particularly episodes that lead to an emergency department (ED) visit. We sought to address this gap and describe ED practice patterns. METHODS Data were collected from the National Hospital Ambulatory Medical Care Survey between 1993 and 2003. We examined(More)
Acute gastric dilatation is a rare complication of anorexia nervosa binge/purge subtype that results from gastrointestinal abnormalities, including decreased gastric motility and delayed gastric emptying. Early diagnosis and intervention is critical since delay may result in gastric necrosis, perforation, shock, and death. We report a 26-year-old female(More)
Objective. We sought to describe the trend in abdominal CT use in adult trauma patients after a point-of-care emergency ultrasound program was introduced. We hypothesized that abdominal CT use would decrease as FAST use increased. Methods. We performed a retrospective study of 19940 consecutive trauma patients over the age of 18 admitted to our level one(More)
CONTEXT Standard teaching is that patients with pneumoperitoneum on plain X-ray and clinical signs of abdominal pathology should undergo urgent surgery. It is unknown if abdominal computed tomography (CT) provides additional useful information in this scenario. AIMS The aim of this study is to determine whether or not CT scanning after identification of(More)
IMPORTANCE With the dramatic growth in the very old population and their concomitant heightened exposure to traumatic injury, the trauma burden among this patient population is estimated to be exponentially increasing. OBJECTIVE To determine the clinical outcomes and predictors of in-hospital and 1-year mortality in nonagenarian and centenarian trauma(More)
BACKGROUND For patients with acute pancreatitis complicated by infected necrosis, minimally invasive techniques have taken hold without substantial comparison with open surgery. We present a contemporary series of open necrosectomies as a benchmark for newer techniques. METHODS Using a prospective database, we retrospectively identified consecutive(More)
BACKGROUND Preoperative diagnostic evaluation (PDE) of penetrating esophageal injury (PeEsIn) can delay treatment and increase morbidity. We sought to study the relationship among PDE, delay in definitive treatment, and patient mortality in PeEsIn. MATERIALS AND METHODS The 2008-2010 National Trauma Data Banks were queried for PeEsIn. Exclusion criteria(More)
BACKGROUND AND OBJECTIVES Meckel's diverticulum is a common anomaly of the gastrointestinal tract that may result in gastrointestinal bleeding, diverticulitis, and small bowel obstruction. This report describes the use of laparoscopy to treat a rare complication of Meckel's diverticulum-small bowel obstruction due to phytobezoar impaction. More generally,(More)
