In management of STEMI, time to treatment is critical. PCI is always better than thrombolytic therapy. According to ACC/AHA guidelines, door to balloon time for PCI should be less than 120 minutes. However, according to data from MITI trial if the patient is seen within 70 minutes of onset of symptoms, prehospital fibrinolytic therapy is very useful and is associated with better outcomes. Even ...

ABSTRACT Objective: Teaching basic life support to schoolchildren is well established as one of the most effective strategies in increasing bystander CPR rates. However, there a lack scientific evidence concerning Portuguese pediatric population. The present study aims evaluate outcome training session on theoretical knowledge and self-efficacy, immediately after 6 months later, Methods: A tota...

PURPOSE Weak direct currents induce lasting alterations of cortical excitability in animals and humans, which are controlled by polarity, duration of stimulation, and current strength applied. To evaluate its anticonvulsant potential, transcranial direct current stimulation (tDCS) was tested in a modified cortical ramp-stimulation model of focal epilepsy. METHODS The threshold for localized s...

OBJECTIVE To improve the psychometric properties of the objective structured clinical examination (OSCE) and elevate staff motivation. METHODS The OSCE was conducted in May 2006 at the Department of Surgery, King Saud University, Riyadh, Saudi Arabia as a pilot study for 95 students split over 2 consecutive days lasting 120 minutes each day. There were 15 actual stations on each day consistin...

The authors evaluated the efficacy of an electronic treatment for pain, using an ion flow generator, BE-101 model by Bio-Ejt, on 19 patients suffering from acute pain of an arthrorheumatic nature. Each patient was treated for two weeks every other day (6 sittings), each sitting lasting 20 minutes at an intensity of about 30 microAmper for both transducers. The results demonstrated that this tec...

BACKGROUND Since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in NICU. This study aimed to investigate the effects of prone and supine positions on oxygenation (SPO(2)) in premature infants under mechanical ventilation and comparing infants' oxygen...

It was the aim of this study to investigate differences in fluoride bioavailability in different oral areas after the application of amine fluoride (AmF) and sodium fluoride (NaF). The null hypothesis suggested no differences in the fluoride bioavailability. The tongue coating was removed and biofilm samples from the palate, oral floor and cheeks were collected. All subjects brushed their teeth...
