Despite the fact that 8 years has elapsed since the end of the imposed war, chemically injured victims are still suffering from various long-term complications, most of them respiratory in nature. The progressive nature of respiratory problems in these patients suggests that the immune system must be involved to Initiate a cascade which ends up causing lung injuries. To evaluate this, humo...

Chronic lung disease (CLD) or bronchopulmonary dysplasia (BPD) occurs in preterm infants who require respiratory support in the first few days of birth. Apart from prematurity, oxygen therapy and assisted ventilation, factors like intrauterine/postnatal infections, patent ductus arteriosus, and genetic polymorphisms also contribute to its pathogenesis. The severe form of BPD with extensive infl...

Background: Chronic Obstructive Pulmonary Disease (COPD) is a chronic lung disease characterized by progressive and irreversible obstruction of the airways of the lungs. Different studies have emphasized on the role of Vascular Endothelial Growth Factor (VEGF) in COPD patients. The aim of this study was to investigate the relationship of this factor with disease severity and th...

introduction: pulmonary involvement is the most common cause of mortality and disability in patients with systemic sclerosis and it significantly affects the quality of life in these patients. therefore, early diagnosis and treatment of pulmonary involvement seems necessary in patients with ssc. in this study, we aimed to assess the health-related quality of life (hrqol) in patients with sclero...

A case of a 19-year-old with severe chronic obstructive pulmonary disease is presented. This case illustrates genetic (severe alpha-1 antitrypsin deficiency) and host factors (such as developmental diaphragmatic hernia and the innate response to injury), and environmental (high oxidative stress and lung injury) interactions that lead to severe chronic obstructive lung disease. The development o...

Bronchial provocation challenges with exercise and methacholine were performed on the same day or within a short interval in 52 children with asthma, 22 with other types of chronic lung disease (including cystic fibrosis), and 19 control subjects with no evidence of chronic lung disease. There were no significant differences in the baseline lung function before the two types of challenge in the...

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive lung disease resulting from exposure to cigarette smoke, noxious gases, particulate matter, and air pollutants. COPD is exacerbated by acute inflammatory insults such as lung infections (viral and bacterial) and air pollutants which further accelerate the steady decline in lung function. The chronic inflammatory process in t...

objective: an association between poor oral health and chronic lung disease has recently been reported. the purpose of this study was to explore this potential association between asthma and periodontal disease. materials and methods: this is a descriptive case controlled study. the samples were selected from patients referred to respiratory disease clinic in a hospital in tehran, iran. the stu...

Idiopathic pulmonary haemosiderosis is a rare disorder, with recurrent life-threatening alveolar haemorrhages and chronic lung parenchymal changes. It associated triad of haemoptysis, iron deficiency anaemia, diffuse infiltrates. Although most cases are idiopathic, secondary linked to known diseases has also been observed. Most the remain undiagnosed because disease very low on list differentia...

conclusions since parents’ behaviors affect their children, it is advisable to implement effective interventional programs to increase parents’ awareness about smoking and its harmful environmental effects. results results of the study showed that 76.4% of children knew what a cigarette is; 41.2% had talked about smoking with their parents; 1.4% had asked to buy one due to the attractive appear...
