Primary ciliary dyskinesia (PCD) is associated with abnormalities in the structure of a function of motile cilia, causing impairment of muco-ciliary clearence, with bacterial overinfection of the upper and lower respiratory tract (chronic oto-sino-pulmonary disease), heterotaxia (situs abnormalities), with/without congenital heart disease, abnormal sperm motility with male infertility, higher f...

Respiratory viruses can cause a wide spectrum of pulmonary diseases, ranging from mild, upper respiratory tract infections to severe and life-threatening lower respiratory tract infections, including the development of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Viral clearance and subsequent recovery from infection require activation of an effective host immune resp...

BACKGROUND: Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most important and pathogenic mycoplasma in chicken production. The tendency of avian mycoplasma for interaction with other pathogen is well-known. Interaction within several disease-producing factors in respiratory tract exacerbate the disease and known as multicausal respiratory disease. OBJECTIVES: In recent years...

Respiratory are a cause functional morphological disorders mucosa which is protective barrier against various damaging agents. It necessary to use complex drugs that preserve restore physiolo...

OBJECTIVE To characterize social inequalities that represent risk conditions for respiratory tract diseases in children and to describe geoprocessing techniques to identify homogeneous social groups and intervention actions for health promotion. METHODS The study area comprised the surroundings of a health school center in the city of S o Paulo. Based on 1991 census, housing data on 49 census...

Respiratory infections have been implicated in the origin and exacerbation of asthma in a variety of ways; however, systemisation of this knowledge in a way helpful for disease management remains suboptimal. Several conceptual issues need to be taken into account: the fact that the effects of an infection may vary according to genetic background, the current immune status of the host, and paral...

In order to assess the effect of air pollution on pediatric respiratory morbidity, we carried out a time series study using daily levels of PM10, SO2, NO2, ozone, and CO and daily numbers of pediatric respiratory emergency room visits and hospital admissions at the Children's Institute of the University of Sao Paulo Medical School, from August 1996 to August 1997. In this period there were 43,6...

BACKGROUND The microbiota of the gastrointestinal tract have profound influence at multiple levels, even on the development and maintenance of lung immunity and inflammation. Aim of this review is to evaluate the current knowledge about the specific impact on children's respiratory tract infections from probiotics, live microbes with the power to modify intestinal microbial populations and exer...
