Background: Flour dust is one of the allergens in the workplaces and its occupational exposure can cause respiratory impairments. The purpose of this study was to investigate the respiratory effects of exposure to flour dust in flour mill workers. Methods: This cross-sectional study was carried out at 6 flour producing factories in Razavi and South Khorasan provinces, Iran. Study subjects incl...
Background: Asthma is a life-threatening disease that can cause death due to bronchospasm. In addition to clinical symptoms such as wheezing, acute paroxysmal dyspnea, chronic cough after exposure to cold air or cough after exercise, spirometry is also necessary for the diagnosis of asthma. The association between respiratory symptoms and a positive methacholine challenge test (MCT) is still co...
Background and aims: The purpose of this study was to assess the prevalence of respiratory symptoms (phlegm, cough, shortness of breath and wheezing) and lung functional impairments associated with occupational inhalation exposure to carbon black (CB) dust among employees of a rubber industry. Methods: All of the eligible, CB exposed, employees of the industry (72 subjects) as well as 69 unex...
cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...
The centronuclear myopathies (CNMs) are a group of inherited neuromuscular disorders classified as congenital myopathies. While several causative genes have been identified, some patients do not harbor any of the currently known mutations. These diverse disorders have common histological features, which include a high proportion of centrally nucleated muscle fibers, and clinical attributes of m...
introduction: evaluation of persistent vertigo in post infarct patients is very important as the management depends on whether the cause is purely of central origin or due to associated vestibular affliction. case report: a patient with left sided dorsolateral medullary syndrome and persistent vestibular symptoms was evaluated. vestibular test battery showed abnormal smooth pursuit, bilateral...
Introduction: Ischemic preconditioning (IPC) protects skeletal muscles from ischemia-reperfusion injury and improves physical exercise performance. The purpose of the present study was to determine whether application of remote ischemic preconditioning (RIPC) of upper limbs would affect the pulmonary function tests and the maximal oxygen consumption (VO2max). Methods: Twenty healthy trained...
Background: Acquired paralysis of the diaphragm is a condition caused by trauma, surgical injuries, (lung cancer surgery, esophageal surgery, cardiac surgery, thoracic surgery), and is sometimes of an unknown etiology. It can lead to dyspnea and can affect ventilatory function and patients activity. Diaphragmatic plication is a treatment method which decreases inconsistent function of diaphragm...
