BACKGROUND Dichlorodiphenyldichloroethylene (DDE) and other organochlorines suppress immunity biomarkers in animals and humans. Our aim was to study the association between prenatal levels of DDE and lower respiratory tract infection in infants independently from polychlorinated biphenyls (PCBs) and other organochlorines. METHODS Maternal levels of p'p'-DDE, dichlorodiphenyltrichloroethane (p...

Thirty preschool children presenting with recurrent respiratory infections and their unaffected siblings were observed prospectively for a year. The index children experienced more episodes of acute respiratory infection than their siblings. Respiratory viruses were the major cause of respiratory infections. The index children had lower respiratory tract disease, predominantly wheeze, during 34...

AIM In our study, we aimed to clinically and epidemiologically evaluate respiratory tract infections the viral agents of which were detected by molecular methods and to compare influenza and other respiratory tract viruses in this context. MATERIAL AND METHODS The records of 178 patients aged above 2 years who presented to pediatric emergency outpatient clinic with fever and respiratory tract...

mycoplasma is an important respiratory tract pathogen worldwide, causing respiratory tract infection in small ruminants ( sheep and goats). it is a bacterium that causes acute respiratory illness ranging in severity from mild respiratory illness to severe pneumonia. mycoplasmosis in small ruminants is a serious and major problem in iran. this study was determined to isolate mycoplasma species a...

The human bocavirus (HBoV) was recently isolated from respiratory tract samples. Within a study collective of children with severe lower respiratory tract disease, the patients testing positive for HBoV (12.8%) had a higher rate of underlying cardiopulmonary disease. Viral loads in respiratory tract specimens varied from 10(2) to 10(10) genome equivalents/ml.

OBJECTIVE To assess the effectiveness of adenoidectomy in children with recurrent upper respiratory tract infections. DESIGN Open randomised controlled trial. SETTING 11 general hospitals and two academic centres. PARTICIPANTS 111 children aged 1-6 with recurrent upper respiratory tract infections selected for adenoidectomy. INTERVENTION A strategy of immediate adenoidectomy with or wit...

The International Agency for Research on Cancer and the World Health Organization have designated airborne particulates, including particulates of median aerodynamic diameter ≤ 2.5 μm (PM2.5), as Group 1 carcinogens. It has not been determined, however, whether exposure to ambient PM2.5 is associated with an increase in respiratory related diseases. This meta-analysis assessed the association b...

Pulse oximetry was used to measure transcutaneous arterial oxygen saturation in infants aged 2 to 11 months prone and supine in quiet sleep. Groups of healthy infants (n = 34), infants with upper respiratory tract infections (n = 13), and infants with generalised moderately severe lower respiratory tract infections (n = 17) were studied. No clinically important differences were demonstrated in ...

Abstract Anelloviruses (AVs) are ubiquitous in humans and the most abundant components of commensal virome. Previous studies on diversity, transmission persistence AVs mainly focused blood or transplanted tissues from adults; however, profile anellome respiratory tract children barely known. We investigated their dynamics upper a cohort with acute infections (ARTIs). Different to that adult, be...

Acute otitis media (AOM), sinusitis and tonsillopharyngitis are respiratory tract infections frequently encountered by primary-care physicians. Increasing bacterial resistance, particularly in Streptococcus pneumoniae, which is one of the most important respiratory tract bacteria implicated in community-acquired respiratory tract infections, has led to concern about the current options for empi...
