BACKGROUND Only few studies have assessed the relative impact of prenatal and postnatal exposure to tobacco smoke on the child's later asthma or chronic respiratory symptoms and to our knowledge no studies have elaborated respiratory infections and allergies in this context. OBJECTIVE To assess the effects of prenatal and postnatal exposure to tobacco smoke on respiratory health of Russian sc...
Background: Air pollution, especially the phenomenon of dust and particulate matter can cause mortality of many civilians, and causes various diseases including cardiovascular and respiratory diseases. One of the major pollutants in the air is particulate matter that concentration has increased over recent years. So, present study with aim of Quantification Health Endpoints Attributed to partic...
In Lebanon, childhood asthma is an important disease and pesticides are commonly used. The objective of this study was to evaluate whether exposure to pesticides has chronic effects on the respiratory health of Lebanese children. A cross-sectional study was performed on children from a randomly selected sample of Lebanese public schools. Exposure to pesticides was evaluated by a standardised qu...
more than 45,000 of 100,000 exposed patients are suffering from late effects of sulfur mustard (sm) after almost 20 years post-exposure. respiratory complications of sm exacerbate over time and are the greatest cause of long-term disability in exposed patients. a triad of cough, expectoration and dyspnea has been found to be the main symptoms among patients. even those who had not developed acu...
Background: establishing a regular respiratory condition in the infants is one of the basic considerations in NICU. Newborns show noticeable breath alterations in response to even low concentrations of some fragrance. Aim: determining the effect of breast milk odor on oxygen saturation and respiratory rate in premature infants. Methods: In this four-group randomized clinical trial, 180 prematu...

The International Agency for Research on Cancer and the World Health Organization have designated airborne particulates, including particulates of median aerodynamic diameter ≤ 2.5 μm (PM2.5), as Group 1 carcinogens. It has not been determined, however, whether exposure to ambient PM2.5 is associated with an increase in respiratory related diseases. This meta-analysis assessed the association b...
Background and Objectives: Silica is an inorganic material that found in the nature in various forms. The hazards of crystal of silica or α-quartz (free silica) is greater than other forms. Exposure to dust that contains free silica result to pulmonary injury and result to silicosis and death finally. The present research was conducted in order to evaluate the level of workers exposure to free ...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
BACKGROUND Work related dust exposure is a risk factor for acute and chronic respiratory irritation and inflammation. Exposure to dust and cigarette smoke predisposes to exogenous viral and bacterial infections of the respiratory tract. Respiratory infection can also act as a risk factor in the development of atherosclerotic and coronary artery disease. AIMS To investigate the association of ...
