The 2 groups are children aged 0-5 years and treated by PI and followed since birth during years 2003-2018. Study group consists of children diagnosed at least 2 times as AH and control group as similar children with UTI, GE, vomiting or diarrhea. Respiratory problems (pneumonia, bronchopneumonia, bronchitis), ear problems (otitis media OM, serous OM), antibiotic treatment, use of bronchodilators, inhaled corticosteroid (ICS), chest X-rays, anomalous laboratory results, emergency room visits and hospitalization rates will be compared in the two groups, together with details concerning feeding position during the first years of life. Correlation between morbidity, degree of nasopharyngeal obstruction, allergy, GER and supine feeding position, will be evaluated.
500 children aged 0-5 years followed since birth by Principal Investigator (PI)since January1, 2003 till December 31, 2018 and diagnosed with adenoid hypertrophy (AH) (study group) and 500 children aged 0-5 years followed by principal investigator during the same years and diagnosed as urinary tract infection (UTI), gastroenteritis (GE), diarrhea, vomiting but without AH (control group) were compared.
