OBJECTIVES Acinetobacter baumannii (A. baumannii) is a well-described cause of nosocomial outbreaks and can be highly resistant to antimicrobials. We investigated A. baumannii outbreaks at two Kentucky hospitals to find risk factors for Acinetobacter acquisition in hospitalized patients. METHODS We performed case-control studies at both hospitals. We(More)
Rupture of the diaphragm is almost always due to major trauma and is most commonly associated with road-traffic accidents. We report a case of delayed presentation of a 35-year-old woman with a ruptured diaphragm, 11 days following apparent minor blunt trauma. This case illustrates how the diagnosis of ruptured diaphragm can be missed and demonstrates the(More)
BACKGROUND The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the(More)
Survivors of successful resuscitated cardiac arrest have a high incidence of severe neurological deficits. The pathophysiology of cerebral injury is thought to be multifactorial, and therapeutic mild hypothermia is one of the strategies that have been shown to minimise this complication. In this article, we outline the theoretical basis for this strategy as(More)
INTRODUCTION The prevalence of hiatal hernias and para-oesophageal hernias (PEHs) is lower in Asian populations than in Western populations. Progressive herniation can result in giant PEHs, which are associated with significant morbidity. This article presents the experience of an Asian acute care tertiary hospital in the management of giant PEH and(More)
INTRODUCTION Arterial base excess is an established marker of shock and predictor of survival in trauma patients. However, venous blood is more quickly and easily obtained. This study aimed to determine if venous base excess could replace arterial base excess as a marker in trauma patients at presentation and if venous base excess is predictive of survival(More)
BACKGROUND We studied the safety, effectiveness, and limitations of airway stenting using self-expanding metal stent (SEMS) in patients with malignant central airway obstruction (CAO). METHODS A retrospective review of records of patients undergoing SEMS placement for malignant CAO during year 2013 - 2014 was done. RESULTS Sixteen patients (11 males and(More)
INTRODUCTION The use of an additional biopsy from the gastric body may help improve the detection of Helicobacter pylori during endoscopy. This study aimed to determine whether such an additional biopsy is necessary in routine rapid urease test (RUT), and whether acid suppression and antibiotic therapy affect RUT results. METHODS Patients recruited had(More)
We report a case of a primary parahiatal hernia that was repaired laparoscopically with a composite mesh. A 51-year-old woman presented with vomiting and epigastric pain. CT scan showed a giant paraesophageal hernia with intrathoracic gastric volvulus. Intraoperatively, a diaphragmatic muscular defect was found lateral to an attenuated left crus of the(More)
