BackgroundThe incidence of childhood leukemia has increased annually. Recent studies have shown that childhood leukemia is initiated in utero, and have focused on prenatal risk factors such as birth weight and parental age. Exposure to pesticides and radiation, as well as parental smoking

Children treated for acute lymphoblastic leukemia, the most common cancer in childhood, are at risk for learning problems, including decreased IQ scores and deficits in mathematics, attention, and memory, both during their treatment phase and after cure. Psychosocial problems, particularly

Background: Compelling evidence suggests that childhood leukemia often originates in utero. Birth weight is one of the few pregnancy-related risk factors that has been associated with leukemia risk, but the association has remained poorly characterized. We conducted a population-based case–

Childhood leukemia, particularly acute lymphoblastic leukemia (ALL), haslong been hypothesized to be affected by abnormal immune responses to microbial challengesstemming from a lack of immune modulation in early childhood. Studies of allergies suggest that a child'simmune development may

Cigarette smoke has been linked to adult myeloid leukemia; however, the association between parental smoking and childhood leukemia remains unclear. Parental smoking and the risk of childhood leukemia were examined in the Northern California Childhood Leukemia Study, a case-control study, between

BACKGROUND: During 1990–1991 a childhood leukemia cluster was observed in the sparsely populated region surrounding two nuclear establishments southeast of Hamburg, Germany. Since then, several new cases have been reported. Recently a possible accidental release of radionuclides in 1986

The objectives of this study were to examine the association between contact current exposure and the risk of childhood leukemia and to investigate the relationship between residential contact currents and magnetic fields. Indoor and outdoor contact voltage and magnetic-field measurements were

Urine polyamine: creatinine ratios (nm per mg) measured in eight chil dren with active hematologic cancers were compared with those of age-matched controls and children with hematologic cancer in remission. Polyamine: creatinine ratios in the children with active disease were signifi cantly higher than those of the controls (p < 0.0025) and of the children in remission (p < 0.0025). Putrescine: creatinine ratios were, in general, higher in children with hematologic tumors than in those with solid tumors. Urinary polyamines are thought to reflect variations in bone marrow polyamine content and have been postulated to be an indicator of clinical status.
