Children of farmworkers can be exposed to pesticides through multiple pathways, including agricultural take-home and drift as well as residential applications. Because farmworker families often live in poor-quality housing, the exposure from residential pesticide use may be substantial. We measured eight locally reported agricultural pesticides and 13(More)
The collection of environmental samples presents a responsibility to return information to the affected participants. Explaining complex and often ambiguous scientific information to a lay audience is a challenge. As shown by environmental justice research, this audience frequently has limited formal education, increasing the challenge for researchers to(More)
Adequate housing is a basic human right and an important determinant of environmental health. Little research has documented the housing quality of immigrant Latino farmworker families. This analysis uses data from four surveys of North Carolina farmworker communities conducted in 2001 and 2003 to document aspects of housing quality that could affect(More)
A 9-year-old boy was found to have ruptured sinus of Valsalva aneurysm (RSVA) and aortic coarctation. Following relief of aortic coarctation by balloon angioplasty, transcatheter coil occlusion of the RSVA was performed successfully under transesophageal echocardiographic and fluoroscopic monitoring; bioptome-assisted delivery of 0.052" Gianturco coil was(More)
It has been postulated that nitric oxide (NO) can react with superoxide anion (.O2-) to generate hydroxyl (.OH) radical. If this is correct, inhibition of NO synthesis could attenuate .OH radical mediated ischemia/reperfusion injury. Therefore we studied the effects of NG-nitro-L-arginine (L-NNA), a competitive inhibitor of the NO synthase enzyme on(More)
This paper describes the explanatory model of green tobacco sickness (GTS) held by migrant and seasonal farmworkers in North Carolina and compares it with a research-based biobehavioral model. GTS is a form of acute nicotine poisoning that affects individuals who work in wet tobacco fields. It is characterized by nausea, vomiting, headache, and dizziness.(More)
The case is presented of an infant, referred at the age of 8 hours, who underwent a Waterston anastomosis for pulmonary atresia with intact ventricular septum and a hypoplastic right ventricle. Angiographic studies performed 3 days and 12 months after the Waterston anastomosis clearly demonstrated that kinking was not present soon after the operation but(More)
Since the first description of balloon pulmonary valvuloplasty in 1982 by Kan, the procedure has been extensively utilized by several groups of workers for relief of pulmonary valve stenosis. It is generally recommended that the procedure be performed for peak-to-peak gradients in excess of 50 mmHg. The technique involves positioning one or more balloon(More)
Pesticide exposure has been linked with immediate and delayed health effects. Anyone who lives in a farmworker household may be exposed to pesticides. Studies with farmworkers have found generally low levels of awareness of pesticide exposure and prevention. Less is known about the perceptions of nonfarmworkers living with farmworkers. This article presents(More)
