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…
Mycoplasma pneumonias distribution, epidemiology and prevalence in a triennial survey.
2005
OBJECTIVES. To evaluate: (1) the incidence of pneumonia monthly distribution; (2) the rate of pneumonitis due to Mycoplasma Pneumoniae; (3) the suitability of choosing an empirical-based antibiotic-therapy; (4) the need of a critical revision of Mycoplasma serological data. PATIENTS AND METHODS. We studied 188 patients admitted to the Palermo University Pediatrics Department, from september 1998 to august 2001, with admission diagnosis of pneumonia. RESULTS. The highest incidence of pneumonia was in december and march as in both months 28 cases occurred in the whole period 1998-2001 (average of 9.3 cases per each month). The highest rate of pneumonias by Mycoplasma Pneumoniae was in may wit…
