introduction: the respiratory system is both a route of entry and exit for toxins and injurious agents, as well as being a target for chemical substances and pathogens. therefore, an understanding of the structure and function of the migratory cell populations of pulmonary tissues including alveolar macrophages is central in a number of important disease processes. this study aimed to identify ...

a 69-year-old woman was admitted to hospital 4 times from november 2007 to june 2009. the patient had silicosis complicated by broncholithiasis, esophagobronchial fistula, and relapsed tuberculosis. she had worked as a stone crusher for 3 years and was exposed to a large amount of quartz dust. barium esophagography, gastroesophageal endoscopy, and biopsy suggested esophageal-related chronic inf...

results a total of 43 (12 males and 31 females, with mean age of 41.90 ± 8.64 years) patients underwent minithoracotomy for open lung biopsy. minithoracotomy mortality rate was 0% compared to the 0 - 5.2% reported for thoracoscopy. the mean hospital stay for minithoracotomy was 2.3 ± 0.97 days compared to 4.9 ± 1.53 days reported for thoracoscopy (p < 0.05). the complication rate was 0.05% and ...

background: trinitrotoluene (tnt) is one of the most well-known and oldest explosive agents. in the recent decade, bioenvironmental, biochemical, and biological effects of tnt exposure have been more in the spotlight. in this study, we aimed to evaluate spirometric parameters in workers of a tnt factory exposed to tnt and other related fumes and dusts compared with the unexposed controls. metho...

context worldwide prevalence of respiratory diseases, suffering from such diseases, and heavy cost of treatment, which all may result from lack of etiological understanding of these diseases in modern medicine, were the main factors to conduct the current study. in the present study, the causes and symptoms of asthma were evaluated and compared with those of some other respiratory diseases. ira...

background: in many cases of ild (interstitial lung disease), overlap diagnosis is considered. here, a few cases with diagnosis of a variety of ilds, where eventual open lung biopsy has been performed are selected. reference will be made to reliable sources to show that nsip can still be a variant of uip (usual interstitial pneumonia) with better treatment response and prognosis. case presentat...

background ureaplasma urealyticum (u. urealyticum) and mycoplasma hominis (m. hominis) are two important pathogens in neonatal respiratory tract infections. as low gestational age and birth weight increase the colonization rate with these pathogens, and they are also risk factors of chronic lung disease (cld), it is difficult to establish a statistically significant relation between these two f...

background although the aim of cardiac computed tomographic angiography (cta) is to visualize the cardiac, coronary, and great vessels, portions of noncardiac structures such as lung, mediastinum, bones and abdomen are visible on the scan. some have suggested that the scans should be evaluated in all field of view. some other believe that reporting accidental findings can lead to unnecessary fo...

Health risks from asbestos exposures have been evaluated, considering past professional histories when exposures at workplaces were higher than today. A linear no-threshold (LNT) model has been applied, although its relevance is unproven. Fibers are often found in the lungs and pleura of deceased people. Fiber findings do not prove that a disease is caused by asbestos. It is reasonable to assum...
