herein, we reported on a case of solid type of pulmonary actinomycosis in a 10-year-old boy. he had productive cough for 40 days. bronchoscopy was normal. cmputed tomography revealed a solid large mass in the upper lobe of his left lung with mimicking malignant leisions. he was referred for surgery and underwent left upper lobectomy. macroscopically, the specimen measured 13×9×5 cm and was crea...
Background: Several epidemiological studies conducted on underground miner’s show that exposure to elevated levels of radioactive radon gas is expected to increase the risk of lung cancer. Relative risk of lung cancer is almost linear with radon exposure. Elevated concentrations of radon are not only reported within mines but also for closed indoor environment of general public houses....
Introduction: Exposure to dust is an essential factor in the brick production industry. Determining the mortality rate from silicosis and lung cancer is very important in exposure to crystalline silica dust. Therefore, this study was conducted to risk assessment of workers in machine factories and traditional brick production workshops. Materials and Methods: This cross-sectional study was con...
Abstract Background: Lung cancer is one of the most common cancers around the world. The aim of this study was to use Extended Cox Model (ECM) with Bayesian approach to survey the behavior of potential time-varying prognostic factors of Non-small cell lung cancer. Materials and Methods: Survival status of all 190 patients diagnosed with Non-Small Cell lung cancer referring to hospitals in ...
Background and purpose: Lung cancer is the third cause of death and amongst the five common cancers in Iran. The aim of this study was to analyze the survival rate of patients with lung cancer and identifying the variables influencing their survival. Materials and methods: In a retrospective cohort study, the data was extracted from the medical records of 259 patients with lung cancer who had ...
In spite the emergence of potent and broad spectrum antibiotics and recent advances in bronchoscopy and pulmonary physiotherapy, still there is a high rate of morbidity and mortality because of lung abscess. The objective of this study is the indication of risk factors, which have undesirable effects on the prognosis of lung abscess. In a retrospective study, all cases of lung abscess who was c...
NAD(P)H: quinone oxidoreductase 1 (NQO1) is an endogenous cellular defence mechanism against several carcinogenic quinones derived from cigarette smoke. NQO1 C609T polymorphism is a strong determinant of NQO1 structure and function. The people with mutant allele for this polymorphism has significantly reduced NQO1 activity. In this study, we tried to evaluate the risk of lung cancer as...
oral glutamine supplementation is highly effective in preventing and delaying radiation-induced esophagitis, one of the most common discomforting side effects of radiation to the thoracic area among lung cancer patients. according to the literature, lung cancer is the leading cause of death among all cancers with the highest incidence worldwide. this paper aims to emphasize the importance of or...
background: to determine which radiotherapy parameters are associated with the tumor response of locally advanced non-small cell lung cancer (nsclc) patients undergoing concurrent chemoradiotherapy. materials and methods: thirty one patients with iiia/iiib nsclc underwent chemoradiotherapy with a median dose of 63 gy. on our actual treatments, we made radiotherapy planning to cover the planning...
background: radon is the second leading cause of lung cancer after smoking. in canada, the health authorities have no access to comprehensive profile of the communities built over uranium-rich micro-geological settings. the present indoor radon monitoring guideline is unable to provide an accurate identification of health hazards due to discounting several parameters of housing characteristics....
