BACKGROUND Ventilator associated pneumonia is a major cause of morbidity in the intensive care unit. Difficulties in identification of the risk factors, in diagnosing and in prevention, have intensified the problem. OBJECTIVES To measure the incidence of ventilator associated pneumonia in intensive care unit and to identify the risk factors associated. METHODS A prospective observational co...
INTRODUCTION Nosocomial infections are a major and a frequent problem in neonatal intensive care units and increase morbidity, mortality, and costs. The objective of this study was to identify the risk factors associated with nosocomial infections in a neonatal intensive care unit. METHODS Nested case control study. Records from patients were registered: gestational age, sex, birth weight, ce...
This study was designed to examine the effects of histamine on gastric motility and its specific receptor in the circular smooth muscle of the human gastric corpus. Histamine mainly produced tonic relaxation in a concentration-dependent and reversible manner, although histamine enhanced contractility in a minor portion of tissues tested. Histamine-induced tonic relaxation was nerve-insensitive ...
There is little information concerning the long term outcome of patients with gastro-oesophageal reflux disease (GORD). Thus 109 patients with reflux symptoms (33 with erosive oesophagitis) with a diagnosis of GORD after clinical evaluation and oesophageal testing were studied. All patients were treated with a stepwise approach: (a) lifestyle changes were suggested aimed at reducing reflux and ...
background: icu patients especially those under mechanical ventilation or with a history of coagulation disorders are at the risk of stress ulcer development and related gi bleeding. typically h2 blockers administration showed prophylactic role to control gastric acidity. preliminary studies have shown that administration of intravenous omeperazol is effective. the object of this study was to c...
Two separate studies of 24 hour intragastric acidity were carried out in normal volunteers and duodenal ulcer patients to define the interaction of food and the antisecretory effects of H2-receptor blockers. Both investigations were double blind randomised comparisons using ranitidine 300 mg with either different meal times or ad libitum snacks after an evening meal. Meals taken after drug admi...
BACKGROUND Ventilator associated pneumonia (VAP) is a type of nosocomial pneumonia associated with increased morbidity and mortality. Knowledge about the incidence and risk factors is necessary to implement preventive measures to reduce mortality in these patients. METHOD A prospective study was conducted at a tertiary care teaching hospital for a period of 20 months from November 2009 to Jul...
Recently, we have demonstrated that anti-ulcer drugs, such as H2-receptor blockers and proton pump inhibitors, promote the development of immediate type food allergy toward digestion-labile proteins in mice. The aim of this study was to examine the allergological relevance of these findings in humans. In an observational cohort study, we screened 152 adult patients from a gastroenterological ou...
The contributions of histamine (H1 or H2) receptor-mediated responses and, therefore, the effects of histamine blocking agents are unclear with regard to regulation of proximal epicardial and distal resistance coronary arteries. This study was designed to evaluate the effects of selective H1- and H2-receptor antagonists on epicardial and resistance vessels in the closed chest dog model. Histami...
infantile haemangiomas (ih) are the most common vascular tumors occurring in early childhood, with a prevalence of approximately 5-10% of infants. these vascular tumors are divided into two main groups including infantile haemangioma and vascular malformations. although, haemangioma of infancy are common, benign and self-limited tumors, a significant percent of these lesions are associated with...
