In six patients with acanthosis nigricans variable degrees of glucose intolerance, hyperinsulinemia and marked resistance to exogenous insulin were found. Studies of insulin receptors on circulating monocytes suggest that the insulin resistance in these patients was due to a marked decrease in insulin binding to its membrane receptors. When these patients(More)
OBJECTIVE To assess the impact of large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia (CIN) on cervical morphology as assessed by three-dimensional ultrasound. DESIGN Prospective observational study. SETTING University Hospital in Dublin. POPULATION Women with CIN who underwent an LLETZ procedure. METHODS(More)
INTRODUCTION Central venous catheterization is commonly used in critically ill patients and may cause different complications, including infection. Although there are many studies about CVC-related infection, very few have analyzed it in detail. The objective of this study was to analyze the incidence of catheter-related local infection (CRLI) and(More)
OBJECTIVE The aim of this study was to analyze the prevalence of ventilator-associated pneumonia (VAP) using a closed-tracheal suction system vs. an open system. DESIGN Prospective and randomized study, from October 1, 2002, to December 31, 2003. SETTING A 24-bed medical-surgical intensive care unit in a 650-bed tertiary hospital. PATIENTS Patients(More)
To describe the incidence of the catheter-related local infection (CRLI) and catheter-related bloodstream infection (CRBSI) of central venous catheters (CVCs) and arterial catheters (ACs). Prospective, observational study. A 24-bed medical-surgical intensive care unit of a 650-bed university hospital. We included 988 consecutive patients admitted to the ICU(More)
BACKGROUND There is a vast amount of information published regarding the impact of 2009 pandemic Influenza A (pH1N1) virus infection. However, a comparison of risk factors and outcome during the 2010-2011 post-pandemic period has not been described. METHODS A prospective, observational, multi-center study was carried out to evaluate the clinical(More)
INTRODUCTION Which particular arterial catheter site is associated with a higher risk of infection remains controversial. The Centers for Disease Control and Prevention guidelines of 1996 and the latest guidelines of 2002 make no recommendation about which site or sites minimize the risk of catheter-related infection. The objective of the present study was(More)
INTRODUCTION The importance of accidental catheter removal (ACR) lies in the complications caused by the removal itself and by catheter reinsertion. To the best of our knowledge, no studies have analyzed accidental removal of various types of catheters in the intensive care unit (ICU). The objective of the present study was to analyze the incidence of ACR(More)
BACKGROUND Serum soluble CD40 Ligand (sCD40L) levels, which exhibit prothrombotic and proinflammatory properties, have not been studied in patients with traumatic brain injury (TBI). Thus, the objective of this study was to determine whether serum sCD40L levels are associated with severity and mortality in patients with severe TBI. METHODS This was a(More)
