INTRODUCTION Symptoms of dyspepsia are common but most patients do not have major upper gastrointestinal pathology. Endoscopy is recommended for dyspeptic patients over the age of 45, or those with certain "alarm" symptoms. We have evaluated the effectiveness of age and "alarm" symptoms for predicting major endoscopic findings in six practising endoscopy centres. METHODS Clinical variables of...

Objective- The objective of the present study was to determine the changes in heart rate, respiratory rate and arterial Oxygen saturation (SpO2) by administration of three drug combinations during upper gastrointestinal endoscopy. Design- Experimental study. Animals- 21 healthy and adults dog were randomly divided into three groups. Procedures- The IV combination of 6.5 mg/kg ketamine and 0....

BACKGROUND While the effectiveness of upper endoscopy has been established for acute nonvariceal upper gastrointestinal tract hemorrhage, its optimal timing has not been clearly defined. Early endoscopy has been advocated for its ability to achieve prompt diagnosis, risk stratification, and therapeutic hemostasis. OBJECTIVE To determine whether early vs delayed endoscopy improves patient and ...

BACKGROUND Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. AIMS To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. METHODS...

a total of360 iranian combatants who were exposed to mustard gas by the iraqi forces in the war fronts were studied. acute effects and gastrointestinal (gi) complications of sulfur mustard (s m) intoxication were studied separately in iranian combatants admitted to imam reza hospital from january 1984, to may 198x, in order to record the clinical and paraclinical findings, a special examination...

Nonvariceal upper gastrointestinal bleeding is unique from variceal bleeding in terms of patient characteristics, management, rebleeding rates, and prognosis, and should be managed differently. The majority of nonvariceal upper gastrointestinal bleeds will not rebleed once treated successfully. The incidence is 80 to 90% of all upper gastrointestinal bleeds and the mortality is between 5 to 10%...
