Purpose: Investigating the prevalence of hyperuricemia and its association with metabolic syndrome (MetS) and cardiometabolic risk factors (CMRFs) in Korean children and adolescents. Methods: This cross-sectional survey used data from the 7th Korea National Health and Nutrition Examination Survey (2016–2017); 1,256 males and females aged 10–18 years were included.

The deficiency of enzyme hypoxanthine-guanine phosphoribosyltransferase(HPRT) results in hyperuricemia and subsequently manifests in diverse symptoms. Lesch-Nyhan syndrome is a disorder characterized by hyperuricemia, mental retardation, choreoathetosis, spasticity and self-mutilation, resulting from complete deficiency of the enzyme, whereas partial deficiency of the enzyme shows symptoms of milder forms more often without abnormal neurologic signs. A 7-year-old boy with normal growth and...

Lesch-Nyhan syndrome is an X-linked recessive disorder characterized by hyperuricemia, choreoathetosis, spasticity, mental retardation, and compulsive, self-injurious behavior. This disorder results from a complete deficiency of the purine salvage enzyme, hypoxanthine-guanine phosphoribosyl transferase(HPRT). We report here on a case of Lesch-Nyhan syndrome in a 1-year, 7-month-old male who presented with frequent vomiting, failure to thrive, and developmental delay. The diagnostic...

To assess the incidence and the effectiveness of preventive measures for tumor lysis syndrome, we analyzed the serial electrolytes levels in leukemia (Group A, 15 patients) and in lymphoma (Group B, 8 patients) patients. The results were 1)Serum LDH were elevated in all of the patients before the chemotherapy. 2)Serum uric acid were also elevated in 8 patients (A 5, B...
