Objective To investigate clinically and by laboratory methods the most common pediatric infections of the past 5 years in different hospitals and health centers of Northern Greece and study their course through time.
Methods We retrospectively studied the files and the laboratorial examinations of children who attended the emergency room or who were hospitalized in our health institutions. We studied a total of 4865 cases concerning pediatric patients in the last 5 years.
Results We registered 478 (9.8%) cases of upper respiratory system infections, 786 (16.2%) cases of lower respiratory system infections, 353 (7.3%) cases of urinary infections, 543 (11.2%) cases of bronchial asthma attacks and 622 (12.8%) cases of gastroenteritis.
Conclusions There was no improvement found over the past 5 years in the infections status of children:
a) The cases of lower respiratory system infections and the cases of urinary infections have increased through these years (23% and 41% respectively). This could be a result of the generous use of antibiotics as we found new microbial strains responsible for infection that are resistant to the common antibiotics.
b) The cases of upper respiratory system infections and the cases of gastroenteritis were found to be stable.
c) The cases of bronchial asthma attacks increased by 3% due to the increase of new chemical allergiogens.
