Forrester M. Neonicotinoid insecticide exposures reported to six poison centers in Texas [published online ahead of print February 10, 2014]. Hum Exp Toxicol.
Neonicotinoids are a relatively newer class of insecticide. Used primarily in agriculture, neonicotinoids are also used for flea control in domestic animals. Information on human exposures to neonicotinoids is limited. Neonicotinoid exposures reported to Texas poison centers during 2000-2012 were identified and the distribution by selected factors examined. Of 1,142 total exposures, most products contained imidacloprid (77%) or dinotefuran (17%). The exposures were seasonal with half reported during May-August. The most common routes of exposure were ingestion (51%), dermal (44%), and ocular (11%). The distribution by patient age was 5 years or less (28%), 6-19 years (9%), 20 years or more (61%), and unknown (2%); and 64% of the patients were female. Of all, 97% of the exposures were unintentional and 97% occurred at the patient's own residence. The management site was on-site (92%), already at/en route to a health care facility (6%), and referred to a health care facility (2%). The medical outcomes included no effect (22%), minor effect (11%), moderate effect (1%), not followed judged nontoxic (14%), not followed minimal effects (46%), unable to follow potentially toxic (1%), and unrelated effect (4%). The most commonly reported adverse clinical effects were ocular irritation (6%), dermal irritation (5%), nausea (3%), vomiting (2%), oral irritation (2%), erythema (2%), and red eye (2%). The most frequently reported treatments were dilution/wash (85%) and food (6%). In summary, these data suggest that the majority of neonicotinoid exposures reported to the poison centers may be managed outside of health care facilities with few clinical effects expected.

Morris SA, Ethen MK, Penny DJ, et al. Prenatal diagnosis, birth location, surgical center, and neonatal mortality in infants with hypoplastic left heart syndrome. Circulation. 2014;129(3):285-92.
BACKGROUND: Most studies have not demonstrated improved survival after prenatal diagnosis of critical congenital heart disease, including hypoplastic left heart syndrome (HLHS). However, the effect of delivery near a cardiac surgical center (CSC), the recommended action after prenatal diagnosis, on HLHS mortality has been poorly investigated. METHODS AND RESULTS: Using Texas Birth Defects Registry data, 1999 through 2007, which monitored >3.4 million births, we investigated the association between distance (calculated driving time) from birth center to CSC and neonatal mortality in 463 infants with HLHS. Infants with extracardiac birth defects or genetic disorders were excluded. The associations between prenatal diagnosis, CSC HLHS volume, and mortality were also examined. Neonatal mortality in infants born <10 minutes from a CSC was 21.0%, 10 to 90 minutes 25.2%, and >90 minutes 39.6% (P for trend <0.001). Prenatal diagnosis alone was not associated with improved survival (P=0.14). In multivariable analysis, birth >90 minutes from a CSC remained associated with increased mortality (odds ratio, 2.03; 95% confidence interval, 1.19-3.45), compared with <10 minutes. In subanalysis, birth >90 minutes from a CSC was associated with higher pretransport mortality (odds ratio, 6.69; 95% confidence interval, 2.52-17.74) and birth 10 to 90 minutes with higher presurgical mortality (odds ratio, 4.45; 95% confidence interval, 1.17-17.00). Higher surgical mortality was associated with lower CSC HLHS volume (odds ratio per 10 patients, 0.88; 95% confidence interval, 0.84-0.91). CONCLUSIONS: Infants with HLHS born far from a CSC have increased neonatal mortality, and most of this mortality is presurgical. Efforts to improve prenatal diagnosis of HLHS and subsequent delivery near a large volume CSC may significantly improve neonatal HLHS survival.
