An association between kidney stone composition and urinary metabolic disturbances in children.

Objective: To determine kidney stone composition in children and to correlate stone fractions with urinary pH and metabolic urinary risk factors.

Patients And Methods: We studied 135 pediatric patients with upper urinary tract lithiasis in whom excreted or extracted stones were available for analyses. Composition of stones was analyzed.

Epidemiological study of acute poisoning in children: a 5-year retrospective study in the Paediatric University Hospital in Białystok, Poland.

Background: Poisoning among children and youths in the northeastern part of Poland accounted for 25% of the total number of patients admitted to the Hospital Emergency Department of the Paediatric University Hospital of Białystok. We hypothesise that the epidemiology of poisoned paediatric patients admitted is related to increase in 'designer drugs' (mainly amphetamine- and ecstasy-like psychostimulants, hallucinogens and synthetic cannabinoids ('spice') intake, which became popular 5 years ago in our country.

Methods: A retrospective chart review of medical records of 489 patients admitted due to poisoning in the 5-year period (2006-2010).
