Preventive Effect of Cow's Milk Fermented with Lactobacillus paracasei CBA L74 on Common Infectious Diseases in Children: A Multicenter Randomized Co…
2017
Background: Fermented foods have been proposed to prevent common infectious diseases (CIDs) in children attending day care or preschool. Objectives: To investigate the efficacy of dietary supplementation with cow’s skim milk fermented with the probiotic Lactobacillus paracasei CBA L74 in reducing CIDs in children attending day care or preschool. Methods: Multicenter, randomized, double-blind, placebo-controlled trial on healthy children (aged 12–48 months) consuming daily 7 grams of cow’s skim milk fermented with L. paracasei CBA L74 (group A), or placebo (maltodextrins group B) attending day care or preschool during the winter season. The main outcome was the proportion of children who exp…
Upper respiratory tract infections in children: From case history to management
2015
Respiratory tract infections are the most common diseases in childhood. The respiratory tract, widely branched system of ducts, is particularly exposed to the action of microorganisms transmitted by air from here the high frequency of infections they face especially in the first years of life. It is usual distinguish: upper respiratory tract infections (URTI) and lower respiratory tract infections (LRTI). In particular, in infections of the upper airways, the inflammatory process, result of the interaction between microbes and the immune response, can be localized to the mucosa of the nose or sinuses (common cold and sinusitis), or the pharynx or larynx (pharyngotonsillitis and laryngitis) …
THE LINKAGE BETWEEN UPPER RESPIRATORY TRACT INFECTIONS AND OTITIS MEDIA: EVIDENCE OF THE 'UNITED AIRWAYS CONCEPT'
2012
Upper respiratory tract infection (URTI) is a nonspecific term used to describe acute infections involving the nose, paranasal sinuses, pharynx and larynx and resulting from interplay between microbial load (viral and bacterial) and immune response. Infant and young children are prone to developing upper respiratory tract infections, which often result in bacterial complications especially acute otitis media because of the passage of bacteria (colonizing the nasopharynx) in the middle ear via Eustachian tube.
Respiratory syncytial virus inhibits ciliagenesis in differentiated normal human bronchial epithelial cells: effectiveness of N-acetylcysteine.
2012
Persistent respiratory syncytial virus (RSV) infections have been associated with the exacerbation of chronic inflammatory diseases, including chronic obstructive pulmonary disease (COPD). This virus infects the respiratory epithelium, leading to chronic inflammation, and induces the release of mucins and the loss of cilia activity, two factors that determine mucus clearance and the increase in sputum volume. These alterations involve reactive oxygen species-dependent mechanisms. The antioxidant N-acetylcysteine (NAC) has proven useful in the management of COPD, reducing symptoms, exacerbations, and accelerated lung function decline. NAC inhibits RSV infection and mucin release in human A54…
