Susceptibility patterns of uropathogens identified in hospitalized children.

Background: Urinary tract infection (UTI) is the most common serious bacterial infection in childhood. The aim of the present study was therefore to identify the organisms responsible for community-acquired febrile UTI in children, to investigate their susceptibility to commonly used antibiotics, and to identify possible risk factors for antibiotic resistance.

Methods: A total of 284 children (male, 38%; female, 62%), who were hospitalized due to a community-acquired UTI over a 5 year period in a general district hospital of southern Greece, were enrolled in the study.

Interpretation of lymphocyte subset counts by the general pediatrician.

The immune system poses one of the greatest challenges for the scientific community. The general pediatrician should be able to screen and identify an immunodeficient patient based on certain clinical indications. Further investigation is crucial for the distinction between primary or secondary immunodeficiency as well as for between cellular and humoral immunity defects.
