Childhood cancer and residential radon exposure - results of a population-based case-control study in Lower Saxony (Germany)
1999
A population-based case-control study on risk factors for childhood malignancies was used to investigate a previously reported association between elevated indoor radon concentrations and childhood cancer, with special regard to leukaemia. The patients were all children suffering from leukaemia and common solid tumours (nephroblastoma, neuroblastoma, rhabdomyosarcoma, central nervous system (CNS) tumours) diagnosed between July 1988 and June 1993 in Lower Saxony (Germany) and aged less than 15 years. Two population-based control groups were matched by age and gender to the leukaemia patients. Long-term (1 year) radon measurements were performed in those homes where the children had been liv…
Incidence, time trends and regional variation of childhood leukaemia in Germany and Europe.
2008
This paper presents data on the German and Europe-wide incidence, time trends and regional variations of childhood leukaemia. Data were provided by the German Childhood Cancer Registry (GCCR), a population-based cancer registry recording all cases of malignant diseases in children under 15 y of age residing in Germany and by the Automated Childhood Cancer Information System (ACCIS) co-ordinated at International Agency for Research on Cancer, Lyon, that combines and evaluates data from several European population-based cancer registries. The incidence of leukaemia (44.0 per million) has increased in Europe as well as in Germany in the last decades (0.6% annually on average). Germany shows no…
Cancer patterns among children of Turkish descent in Germany: A study at the German Childhood Cancer Registry
2008
Abstract Background Cancer risks of migrants might differ from risks of the indigenous population due to differences in socioeconomic status, life style, or genetic factors. The aim of this study was to investigate cancer patterns among children of Turkish descent in Germany. Methods We identified cases with Turkish names (as a proxy of Turkish descent) among the 37,259 cases of childhood cancer registered in the German Childhood Cancer Registry (GCCR) during 1980–2005. As it is not possible to obtain reference population data for children of Turkish descent, the distribution of cancer diagnoses was compared between cases of Turkish descent and all remaining (mainly German) cases in the reg…
The Burden of Allergic Asthma in Children: A Landscape Comparison Based on Data from Lithuanian, Latvian, and Taiwanese Populations
2012
Asthma is one of the most common chronic respiratory diseases with an increasing prevalence and financial burden worldwide. This disease affects individuals in all countries and all ethnic groups; however, prevalence rates of asthma have been reported to vary significantly between different regions. To understand the origin of asthma and to manage it effectively, it is necessary to analyze the genetic and environmental factors that cause these geographic differences. Therefore, we aimed to review published data from the investigations of asthma patients in Eastern Europe, represented by Latvia and Lithuania, and of patients from Eastern Asia represented by Taiwan. We hope that some of the c…
Early-life weight gain, prematurity, and asthma development.
2014
Early childhood asthma is a clinical syndrome, the development and clinical manifestations of which result from a complex interplay among airway anatomy, physiology, and inflammation. Although multiple phenotypes of early childhood wheezing and asthma have been described, the mechanisms that promote and differentiate these phenotypes remain poorly understood. Over the past decade, substantial understanding has emerged as to the early-life factors that influence childhood asthma development. One area of great interest has been the relationships between patterns of fetal and infant growth, subsequent wheezing, and asthma. Although several studies strongly suggest that intrauterine growth patt…
Gender-Dependent Effect of GSTM1 Genotype on Childhood Asthma Associated with Prenatal Tobacco Smoke Exposure
2014
It remains unclear whether the GSTM1 genotype interacts with tobacco smoke exposure (TSE) in asthma development. This study aimed to investigate the interactions among GSTM1 genotype, gender, and prenatal TSE with regard to childhood asthma development. In a longitudinal birth cohort in Taiwan, 756 newborns completed a 6-year follow-up, and 591 children with DNA samples available for GSTM1 genotyping were included in the study,and the interactive influences of gender-GSTM1 genotyping-prenatal TSE on childhood asthma development were analyzed. Among these 591 children, 138 (23.4%) hadphysician-diagnosed asthmaat 6 years of age, and 347 (58.7%) werenull-GSTM1. Prenatal TSE significantly incre…
Large proportions of overweight and obese children, as well as their parents, underestimate children's weight status across Europe. The ENERGY (Europ…
2015
AbstractObjectiveTo investigate the magnitude and country-specific differences in underestimation of children’s weight status by children and their parents in Europe and to further explore its associations with family characteristics and sociodemographic factors.DesignChildren’s weight and height were objectively measured. Parental anthropometric and sociodemographic data were self-reported. Children and their parents were asked to comment on children’s weight status based on five-point Likert-type scales, ranging from ‘I am much too thin’ to ‘I am much too fat’ (children) and ‘My child’s weight is way too little’ to ‘My child’s weight is way too much’ (parents). These data were combined wi…
Incidence, Trends, and Survival of Children With Embryonal Tumors.
2015
BACKGROUND: Central nervous system (CNS) and non-CNS embryonal tumors occur principally in children and are rarely seen in adults. The incidence rates for rare entities such as atypical teratoid/rhabdoid tumors (AT/RT) or primitive neuroectodermal tumors in the CNS are rarely published. Incidence rates for certain subgroups, such as hepatoblastomas, have been increasing in some countries. METHODS: Data of 8337 embryonal tumors, registered in children (0–14 years) between 1991 and 2012 (for AT/RT 2000–2012) in the population-based German Childhood Cancer Registry with complete national coverage were analyzed for incidence rates, time trends, and survival. RESULTS: For most entities, the inc…
Survivors of childhood cancer for more than twenty years.
2001
Present health status, complications, and development of long-term survivors of childhood cancer followed for more than 20 years in a single institution were reviewed. The departmental database was searched to identify patients diagnosed with childhood cancer and consequently treated between 1965 and 1978. A total of 124 (77%) long-term survivors participated on a voluntary basis in the study. A semi-standardized interview consisted of measures evaluating the present health condition, sequelae of treatment, second malignancies, intellectual development and presence of offspring of the former patients. The majority of patients were treated with chemotherapy (82%). 67% received radiotherapy a…
Childhood Cancer Risk From Conventional Radiographic Examinations for Selected Referral Criteria: Results From a Large Cohort Study
2011
OBJECTIVE: Little is known about the long-term effects of exposure to diagnostic ionizing radiation in childhood. Current estimates are made with models derived mainly from studies of atomic bomb survivors, a population that differs from today's patients in many respects. MATERIALS AND METHODS: We analyzed the cancer incidence among children who underwent diagnostic x-ray exposures between 1976 and 2003 in a large German university hospital. We reconstructed individual radiation doses for each examination and sorted results by groups of referral criteria for all cancers combined, solid tumors, and leukemia and lymphoma combined. RESULTS: A total of 68 incidence cancer cases between 1980…
