Medulloblastoma is the most common malignant brain tumor in children. Post-surgical craniospinal irradiation (CSI; 30-36 Gy) plus local boost radiation therapy (RT; 54-56 Gy) is a standard treatment for children with medulloblastoma who are over 3 years old, resulting in a 5-year overall survival (OS) rate of 46% to 65% in average-risk patients and 50% in high-risk patients. The addition of chemotherapy has the benefit of reducing complications from radiation and improving the OS rate.

A term newborn with a birth weight of 3,900 g developed hypoglycemia one hour after birth and required up to 20 mg/kg/min of intravenous glucose infusion to maintain euglycemia. Investigations during the critical period revealed an inappropriately high insulin level.

Therefore, systematic screenings of the late complications are essential. The objective of this study was to determine the prevalence of late effects of Thai children and adolescents after completion of ALL therapy.

MDR cancer cells are characterized by the overexpression of multidrug resistance1(MDR1) gene which encodes P-glycoprotein (Pgp), a surface protein of tumor cells that functions to produce an excessive efflux and thereby an insufficient intracellular concentration of chemotherapeutic agents. A variety of studies have sought potent MDR modulators to decrease MDR1 gene expression in cancer cells.

Thus, WT1 mRNA and protein serve as promising tumor markers for the detection of leukemia and monitoring of disease progression. The purpose of this study was to investigate the modulating effects of curcumin on WT1 gene expression in the human leukemic cell line K562.

There were 23 children (14 boys and 9 girls; average age at diagnosis of malignancy, 4.2 years), and the incidence rate was 0.

A total of six mutations of the alpha-globin gene, which produced five genotypes, were detected. All patients had an alpha(0)-thalassemia (thal) deletion on one chromosome 16.

Coinheritance of alpha-thalassemia and hemoglobin E (Hb E) is prevalent in Thailand, where the gene frequencies of thalassemia and hemoglobinopathies are high. Hb E carriers with, concomitant inheritance of alpha-thalassemia 1 are known to have a lower level of Hb E. In this study, we reviewed the Hb E levels in Hb E carriers, who either had or did not have Southeast Asian (SEA)-type alpha-thalassemia, in order to seek a Hb E level that may be used as a predictor for concomitant alpha-thalassemia carrier status.

The purpose of this study was to evaluate psychosocial problems in children with thalassemia and their siblings by using a semi-structured interview and the Pediatric Symptom Checklist (PSC). The study sample included 82 children with thalassemia, 20 siblings, and 50 control children without a chronic illness.
