Unintentional injuries among youth with developmental disabilities in the United States, 2006-2007.

We examined unintentional injury among youth with and without developmental disabilities. Our nationally representative sample included 6369 injured youth, aged 0-17 years, who were seen in one of the 63 US hospital emergency rooms that participated in the National Electronic Injury Surveillance System - All Injury Program (NEISS-AIP) in 2006-2007. Parents or guardians of injured youth were interviewed by telephone after the hospital visit to ascertain disability status.

Persistent lipophilic environmental chemicals and endometriosis: the ENDO Study.

Background: An equivocal literature exists regarding the relation between persistent organochlorine pollutants (POPs) and endometriosis in women, with differences attributed to methodologies.

Objectives: We assessed the association between POPs and the odds of an endometriosis diagnosis and the consistency of findings by biological medium and study cohort.

Methods: Using a matched cohort design, we assembled an operative cohort of women 18-44 years of age undergoing laparoscopy or laparotomy at 14 participating clinical centers from 2007 to 2009 and a population-based cohort matched on age and residence within a 50-mile catchment area of the clinical centers.

Potent induction of tumor immunity by combining tumor cryoablation with anti-CTLA-4 therapy.

Thermal ablation to destroy tumor tissue may help activate tumor-specific T cells by elevating the presentation of tumor antigens to the immune system. However, the antitumor activity of these T cells may be restrained by their expression of the inhibitory T-cell coreceptor CTLA-4, the target of the recently U.S.

Preventing young children's injuries: analysis of data from a population-based surveillance.

The objective of this study is to determine prevention strategies for potentially serious injury events among children younger than 3 years of age based upon circumstances surrounding injury events. Surveillance was conducted on all injuries to District of Columbia (DC) residents less than 3 years old that resulted in an Emergency Department (ED) visit, hospitalization, or death for 1 year. Data were collected through abstraction of medical records and interviews with a subset of parents of injured children.
