Ultrasound diagnosis of masses elevating the inferior vena cava.

The inferior vena cava is frequently involved in diseases of the abdomen and retroperitoneum. Critical evaluation of this vessel's course can greatly help in determining the origin of an adjacent mass. Ultrasound was used to divide the inferior vena cava into three parts. A vector type principle was applied to masses anteriorly displacing the vena cava, and the location of the mass was compared to the particular portion of the cava most affected. With this approach, it was often possible to determine what structures a mass may have originated from.

Water enema: a new ultrasound technique in defining pelvic anatomy.

A new technique is described for delineating pelvic structures by using a distended bladder in combination with a water enema. The distended urinary bladder, which acts as a sonic window to the pelvis, fully defines only the portion of structures that abut against the surface. With fluid in both the bladder and rectosigmoid colon, and occasionally the cecum, a 'sandwich effect' can be obtained, resulting in a more complete definition of interposed structures. Questionable masses that might be feces in the bowel can be easily distinguished from significant pathology. This new technique has the potential for increasing accuracy of diagnosis of pelvic masses and delineating tumor extension of masses arising in such pelvic organs as the bladder, prostate, and uterus.

Association between indoor residential contamination with methyl parathion and urinary para-nitrophenol.

Methyl parathion, a pesticide listed by the U.S. Environmental Protection Agency in Toxicity Category I (i.e., most toxic), is not licensed for indoor use, and human exposure has resulted in the deaths of infants and children. From January 1991 through November 1994, an unlicensed pesticide applicator sprayed the interior of more than 200 homes in Lorain County, Ohio, with methyl parathion. To measure the environmental contamination this spraying caused, we measured methyl parathion in residential samples (air filtration and surface wipe) collected from a subset of 64 homes. To measure human exposure, we collected urine samples from 142 people living in these homes and measured urinary levels of para-nitrophenol, a methyl parathion metabolite. We then used a generalized estimating equation to evaluate the association between residential contamination and human exposure. The model included the age of the resident, the number of days between pesticide application and sample collection, and air and surface-wipe methyl parathion concentrations. As expected, the air and surface-wipe concentrations each had a significant inverse relationship with the number of days between application and sample collection. The model explained 65.7% of the variation in urinary para-nitrophenol concentrations. The form of this model could be used to estimate urine p-nitrophenol in residents exposed to methyl parathion in situations where urine specimens are not available. We recommend site-specific validation of this model.
