Background: 3DCRT (three-dimensional conformal radiotherapy) and IMRT (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. However, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. The purpose of this study is to evaluate the imp...

introduction: gastro-esophageal reflux (ger) is common among children of different ages and treatment is necessary since it could turn in to gastroesophageal reflux disease (gerd) and cause complications. in patients that do not respond to medical treatment and patients that have complications such as repeated apnea, pneumonia, stricture caused by esophagitis and failure to thrive, surgical tre...

background and objective: preterm birth is a public health problem and late preterm birth (deliveries between 34-36 weeks of gestation) accounts for 75% of all preterm births. antenatal betamethasone can reduce the severity of respiratory distress in preterm infants and its effect is accepted in 24-34 weeks of gestation. our goal was to determine the neonatal outcomes of betamethasone prescript...

we aimed to evaluate clinical, high resolution computed tomography (hrct) and pulmonary function test (pft) findings after 18-23 years of exposure in veterans of sulphur mustard (sm) exposure. we performed a cross-sectional study of 106 patients. inclusion criteria were 1: documented exposure to sm as confirmed by toxicological analysis of their urine and vesicular fluid after exposure 2: singl...
