Objective: To verify how efficient respiratory parameters are in the follow-up of subjects with amyotrophic lateral sclerosis (ALS) and to observe possible correlations between respiratory and nutritional functions. Method: Sixteen patients with probable or defined ALS were selected and evaluated over eight months using the following respiratory parameters: spirometry, maximum inspiratory press...

Air pollution is composed of a particulate phase and a gaseous phase. The particulate phase, consisting of dust and aerosols, is the vehicle of toxic pollutants, transporting them into the respiratory tract. The irritants (sulphur dioxide, nitrogen oxides, aldehydes, and hydrocarbons) are the most important pollutants as regards health; the mucous membranes of the eyes and the respiratory tract...

KEY POINTS Children with neurocognitive impairment often present with chronic or recurrent respiratory problems.The respiratory problems have an important impact on quality of life and life expectancy.The underlying causes are multiple: risk of aspiration, insufficient cough, upper airway obstruction and progressive kyphoscoliosis.There is often a complex interplay between these known risk fact...

Viruses are now thought to play an important role in chronic obstructive pulmonary disease pathogenesis. Viral infection and adaptive immunity show complex interactions in this disease. Tobacco, pollutants, immunosenescence, and chronic intake of steroids alter the adaptive immune response. Impairment of the adaptive response potentially predisposes to infection by respiratory viruses. Viral in...

In a coffee growing area of Papua New Guinea, a developing country in the western Pacific region, coffee factory workers were found to have more chronic symptomatic respiratory impairment than a carefully matched group of neighbouring villagers. This impairment was not related to their duration of employment. Coffee factory workers were found also to have a greater prevalence of reversible but ...

introduction: although the main hazard in cement processing is dust, and respiratory tract disorders are the most important group of occupational diseases in this industry, evidence for association between exposures to cement dust and either respiratory symptoms or functional impairment has not been conclusive. this study was, therefore, undertaken to examine, more thoroughly, the effects of oc...

the recently emerged middle east respiratory syndrome coronavirus (mers-cov) emerged in the middle east region in 2012. the virus is phylogenetically related to bat cov, but other animal species like camels and goats may potentially act as an intermediate host by spreading the virus to humans. this virus is thought to cause a severe disease in patients with underlying comorbidities. laboratory ...

respiratory syncytial virus (rsv) is the major cause of lower respiratory tract infections in infants,and also an important factor for hospitalization during the winter months. to determine the prevalence and importance of rsv as a cause of acute lower respiratory tract infection, we carried out a prospective study during 5 months period from november to march 1998 in 6 pediatric hospitals. a n...

background: petrochemical industry emits air pollutants in abundance, which may harm human health, especially the population living near the industry. children are reported to be the population group of main concern since this susceptible population spends the majority of their time outdoors and their active lifestyle can increase their breathing rate, which then leads to a greater inhalation d...

OBJECTIVE To report the neurodevelopmental outcome of infants enrolled in a randomized multicenter trial of early inhaled nitric oxide (iNO) in term and near-term neonates with hypoxic respiratory failure and pulmonary hypertension. STUDY DESIGN Neonates born at > or = 34 weeks gestation who required assisted ventilation and had an oxygenation index > or = 15 and < 25 were randomized to an ea...
