PURPOSE To examine the epidemiology of hospital admissions for acute pancreatitis in the United States. METHODS We compiled data from the 1988-2003 National Hospital Discharge Survey and analyzed it with respect to patient demographics, hospital type and region, procedures performed, length of hospital stay, and inpatient mortality. RESULTS Hospital(More)
BACKGROUND The comet-tail technique of chest ultrasonography has been described for the diagnosis of cardiogenic pulmonary edema. This is the first report describing its use for the diagnosis and monitoring of high-altitude pulmonary edema (HAPE), the leading cause of death from altitude illness. METHODS Eleven consecutive patients presenting to the(More)
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)
Gain-of-function mutations in fibroblast growth factor receptors have been identified in numerous syndromes associated with premature cranial suture fusion. Murine models in which the posterior frontal suture undergoes programmed fusion after birth while all other sutures remain patent provide an ideal model to study the biomolecular mechanisms that govern(More)
OBJECTIVES To determine the direct medical costs of hospitalizations for acute pancreatitis in the United States and analyze the demographic characteristics of hospitalized patients. METHODS We searched the 2003 Healthcare Cost and Utilization Project-National Inpatient Sample for hospitalizations with a primary discharge diagnosis of acute pancreatitis.(More)
BACKGROUND There is currently no systematic approach to evaluating the severity of intraoperative adverse events (iAEs). STUDY DESIGN A 3-phase project was designed to develop and validate a novel severity classification scheme for iAEs. Phase 1 created the severity classification using a modified Delphi process. Phase 2 measured the classification's(More)
Gene therapy has moved from the promise of laboratory investigation to the reality of clinical practice in just the last decade. Various methods for delivery of genes to host cells have been developed and utilized both in vitro and in vivo. From the perspective of the plastic surgeon, gene therapy holds the promise to augment healing in clinical situations(More)
BACKGROUND Clostridium difficile is the most common cause of nosocomial diarrhea, affecting up to 10% of hospitalized patients. Preliminary studies suggest an association between vitamin D status and C difficile infections (CDIs). Our goal was to investigate whether serum 25-hydroxyvitamin D (25(OH)D) levels are associated with CDI severity. METHODS We(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)
Pancreaticoduodenectomy for trauma (PDT) is a rare procedure, reserved for severe pancreaticoduodenal injuries. Using the National Trauma Data Bank (NTDB), our aim was to compare outcomes of PDT patients to similarly injured patients who did not undergo a PDT. Patients with pancreatic or duodenal injuries treated with PDT (ICD-9-CM 52.7) were identified in(More)
