dyspepsia is a common gastrointestinal symptom reported in 2.9-29% of the adult iranian population. this symptom usually results from functional disease, but in one-third of cases an organic cause such as peptic ulcers, esophagitis, and in less than one percent gastric cancer can be found. the timing of an endoscopic evaluation, the value of acid reducing agents, herbal medicine and the role of...

BACKGROUND Upper gastrointestinal (GI) malignancies are an uncommon cause of dyspepsia but of great concern. The aim of this study was to determine the association between alarm features and each type and stage of upper GI malignancies. METHODS Patients who underwent endoscopy for symptoms of dyspepsia between January 2008 and December 2009 were retrospectively collected. Alarm features studi...

ackground & Aims: Alarm features such as dysphaia, weight loss, or anemia raise concern of an upper astrointestinal malignancy in patients with dyspepia. The aim of this study was to determine the diagostic accuracy of alarm features in predicting maligancy by performing a metaanalysis based on the ublished literature. Methods: English-language studes were identified by searching MEDLINE, EMBAS...

BACKGROUND The diagnostic value of alarm features of serious infections in low prevalence settings is unclear. AIM To explore to what extent alarm features play a role in referral to the emergency department (ED) by GPs who face a febrile child during out-of-hours care. DESIGN AND SETTING Observational study using semi-structured, routine clinical practice data of febrile children (<16 year...

Alarms in the ICU sound frequently and 85-99% of cases do not require clinical intervention. As alarm frequency increases, clinicians develop ‘alarm fatigue’ resulting in desensitization, missed alarms, and delayed responses. This is dangerous for the patient when an alarm-provoking event requires clinical intervention but is inadvertently missed. Alarm fatigue can also cause clinicians to: set...

Background. The value of endoscopy in dyspeptic patients is questionable. Aims. To examine the prevalence of significant endoscopic findings (SEFs) and the utility of alarm features and age in predicting SEFs in outpatients with dyspepsia. Methods. A retrospective analysis of outpatient adults who had endoscopy for dyspepsia. Demographic variables, alarm features, and endoscopic findings were r...

A telecommunication system produces daily a large amount of alarm data which contains hidden valuable information about the system behavior. The knowledge discovered from alarm data can be used in finding problems in networks and possibly in predicting severe faults. In this paper, we devise a solution procedure for mining sequential alarm patterns from the alarm data of a GSM system. First, by...
