Association between medication and intestinal intussusception in children: a case-crossover study.

Objectives: This study aimed to assess the association between the appearance of intussusception in children and medication intake in the immediately preceding period (2-15 days).

Methods: A case-crossover design was used. We selected cases of children admitted with a diagnosis of intussusception (International Classification of Diseases, Ninth Revision, 860) to the major hospitals in the city of Valencia, Spain, from 2006 to 2009.

Prenatal exposure to cooking gas and respiratory health in infants is modified by tobacco smoke exposure and diet in the INMA birth cohort study.

Background: Studies that have evaluated the association between exposure to gas appliances emissions at home with respiratory health in children obtained heterogeneous and limited results. The aim of this study is to analyze the association between the use of gas cooking at home during pregnancy and respiratory problems in children during their first year of life.

Methods: In the years 2003 through 2008 pregnant women were enrolled in 4 Spanish areas and visited in different age-points following a common protocol.

Outdoor, but not indoor, nitrogen dioxide exposure is associated with persistent cough during the first year of life.

Background And Aims: Because their lungs and immune system are not completely developed, children are more susceptible to respiratory disease and more vulnerable to ambient pollution. We assessed the relation between prenatal and postnatal nitrogen dioxide (NO(2)) levels and the development of lower respiratory tract infections (LRTI), wheezing and persistent cough during the first year of life.

Methods: The study population consisted of 352 children from a birth cohort in Valencia, Spain.

Indoor and outdoor air concentrations of BTEX and determinants in a cohort of one-year old children in Valencia, Spain.

BTEX is the commonly used term for a group of toxic compounds (benzene, toluene, ethyl benzene, ortho-xylene and meta- and para-xylene), some of which, most notably benzene, are known carcinogens. The aim of this study is to measure the BTEX levels both inside and outside the homes of 352 one-year old children from the Valencia cohort of the INMA study (Spain) and to analyze the determinants of these levels. Passive samplers were used to measure BTEX levels during a 15day period and a questionnaire was administered to gather information on potentially associated factors (sociodemographics, residential conditions, and lifestyle).

Sources of indoor air pollution and respiratory health in preschool children.

We carried out bibliographic searches in PubMed and Embase.com for the period from 1996 to 2008 with the aim of reviewing the scientific literature on the relationship between various sources of indoor air pollution and the respiratory health of children under the age of five. Those studies that included adjusted correlation measurements for the most important confounding variables and which had an adequate population size were considered to be more relevant.

Short-term relationship between meteorological variables and hip fractures: an analysis carried out in a health area of the Autonomous Region of Valencia, Spain (1996-2005).

Introduction: Diverse studies have shown a seasonal influence on the incidence of hip fracture (HF), possibly associated with adverse meteorological conditions. In this paper, we present an analysis of the short-term relationship between meteorological conditions and the incidence of HF in people over 45 years of age living in a Mediterranean climate zone.

Material And Methods: HF cases admitted to the two reference hospitals in the health area were selected.

Levels of pollutants in indoor air and respiratory health in preschool children: a systematic review.

The aim of this paper is thus to identify, evaluate, and summarize in a systematic fashion all the epidemiological studies that have analyzed the association between exposure to specific indoor air pollutants and respiratory disease among children under the age of five. A search was carried out in the main biomedical bibliographic sources in December 2006 and updated in February 2008. The study period covered 12 years (1996-2007).

Environmental factors affecting children's respiratory health in the first years of life: a review of the scientific literature.

The aim of this paper is to quantitatively summarize the original articles on the relationship between environmental hazards and respiratory health in young children. A search was carried out in the main biomedical bibliographical sources in December 2006 and then the results were updated in June 2007. The study period covered 11 years (1996-2006).
