Effects of neonatal dexamethasone or methylprednisolone on rat growth and neurodevelopment.

Background: Clinical studies have demonstrated that premature infants receiving long-term dexamethasone therapy have reduced linear growth, decreased weight gain, and smaller head circumferences. The purpose of the present study was to investigate the effects of the same equivalent doses for anti-inflammatory potency of neonatal dexamethasone and methylprednisolone on rat growth and neurodevelopment.

Methods: The pups were randomly separated into three treatment groups on postnatal day (PD) 3.

Childhood asthma and its relationship with tonsillar tissue.

The aim of this study was to evaluate the prevalence of asthma among 4-17 years old school children and to determine the relationship between frequent tonsillitis, tonsillar hypertrophy and asthma-related symptoms.
