Respiratory diseases are one of the most common health problems among service personnel assigned to contemporary military operations which are conducted in areas characterized by adverse environmental conditions. This article reviews the results of the studies into the prevalence of acute respiratory tract diseases among soldiers of the Polish Military Contingent deployed to Iraq and Afghanista...

Introduction: This research was a retrospective study on the prevalence of nosocomial infections (NIs) and the associated risk factors among the patients admitted to the surgery and internal Intensive Care Units (ICU). Materials and Methods: This cross-sectional descriptive study was conducted on patients admitted to ICUs over one year. Clinical data of patients, including demographic informat...

Feline Viral Upper Respiratory Tract Disease Feline viral upper respiratory tract disease is typified by signs of rhinosinusitis, conjunctivitis, lacrimation, salivation, and/or oral ulcerations. The principal causative agents are feline herpesvirus type 1 (FHV-1 ) and feline calicivirus (FCV). These viruses are host-specific and pose no known human risk. Other infectious agents (e.g. Bordetell...

background: air pollution is one of the most important factors threatening the health of citizens. it increases the prevalence of cardiovascular and respiratory diseases as well as emergency admissions to hospitals in the polluted metropolitan cities. the present study was conducted using air quality (airq) model and aimed to investigate the effects of air pollution on the number of emergency c...

This study is aimed at creating a stochastic model, named Brazilian Climate and Health Model (BCHM), through Poisson regression, in order to predict the occurrence of hospital respiratory admissions (for children under thirteen years of age) as a function of air pollutants, meteorological variables, and thermal comfort indices (effective temperatures, ET). The data used in this study were obtai...

Both allergic rhinitis and bronchial asthma are inflammatory diseases in the respiratory tract. The upper and lower airways share many anatomical, physiological, and histological properties. A close relationship between allergic rhinitis and asthma has been established, and the “united airway disease hypothesis” proposes that upper and lower airway diseases are both manifestations of a single i...

background disability is a relatively common problem in children. the pattern of admission in these children and their common infections may differ from other children because of their special disabilities. objectives we aimed to determine common infectious diseases resulting in admission of these children to our hospital. patients and methods between september 2006 and september 2007, 60 disab...

BACKGROUND Aerosolized medications are increasingly being used to treat respiratory diseases in dogs. No previous studies assessing respiratory tract deposition of radiolabeled aerosols have been performed in conscious dogs. HYPOTHESIS/OBJECTIVES Assess respiratory tract deposition of radiolabeled, inhalant corticosteroid (fluticasone propionate labeled with 99m Tc) delivered from a nebulizer...
