The consequences of adventitious infectious agents upon the interpretation of toxicology studies performed in rats and mice are incompletely understood. Several prevalent murine pathogens cause alterations of the respiratory system that can confuse the assessment of chemically induced airway injury. In some instances the pathogenesis of infection with these agents has been relatively well studi...
Background :Despite the presence of many textile and dyeing plants in Iran, we couldn’t find similar studies in this country. Forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. The present study was performed to evaluate the respiratory system in dyeing workers. Methods : In a cross-sectional stu...
Cadmium poisoning has been reported from many parts of the world. It is one of the global health problems that affect many organs and in some cases it can cause deaths annually. Long-term exposure to cadmium through air, water, soil, and food leads to cancer and organ system toxicity such as skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems...
Primary immunodeficiency diseases (PIDs) is a diverse group of diseases, characterized by a defect in the immune system. These patients are susceptible to recurrent respiratory infections, gastrointestinal problems, autoimmune diseases, and malignancies. In most cases, patients with primary immunodeficiency disorders have genetic defects and are monogenic disorders that follow a simple Mendelia...
Introduction Stroke is a common neurological disease that can have a negative effect on all parts of the body. The respiratory system is one of the parts of the body that may be damaged by stroke. The respiratory disorders caused by stroke can occur in all three sections of the breath; including metabolic respiration, behavioral respiration and emotional respiration. Disorder in each of these ...
The respiratory epithelium is a primary site for the deposition of microorganisms that are acquired during inspiration. The innate immune system of the respiratory tract eliminates many of these potentially harmful agents preventing their colonization. Collectins and cationic antimicrobial peptides are antimicrobial components of the pulmonary innate immune system produced by respiratory epithe...
Introduction:Guillain-Barre Syndrome(GBS) is the most common cause of acute flaccid paralysis. Respiratory failure is the most serious short-term complication of GBS and invasive mechanical ventilation is required in 30% of patients.moreover,60% of those who are intubated develop major complications including pnemonia,sepsis,GI bleeding and pulmonary embolism. Thus respiratory failure predictio...
A total of 303 young children with acute respiratory tract illnesses were examined for viral and bacterial agents. The isolation of Haemophilus influenzae from 58 (19.1%) of the children was described in relation to respiratory viruses and other bacterial agents isolated at the same time. H. influenzae was isolated alone in 24 instances. Streptococcus pneumoniae and respiratory syncytial virus ...
Bacteria Etiological Agents Causing Lower Respiratory Tract Infections and Their Resistance Patterns
Background: Lower respiratory tract infections (LTRIs) are among the most common infectious diseases with potential life-threatening complications. Methods: The study consisted of 426 patients with suspected LTRIs from mid and far western region of Nepal between September 2011 and July 2014. The specimens were collected and processed according to the standard microbiological methods at the Cent...
