Does dehydration increase the renal response to atrial natriuretic peptide in fetal sheep?
These results demonstrate that in the fetus at 113 days' gestation plasma atrial natriuretic factor levels increase with dehydration, probably a result of decreased plasma atrial natriuretic factor clearance, and the fetal renal responsiveness to atrial natriuretic factor infusion increases during maternal dehydration.
The RCL does not invariably bisect or fall within the middle third of the capitellum in normal pediatric elbows. Therefore, an abnormal RCL is suggestive but not pathognomonic for injury such as Monteggia fracture. An RCL drawn along the radial shaft will miss the capitellum in 15.6% of elbows. The most consistent RCL is drawn along the radial neck on the lateral view. Patient variables such as age and sex should be considered in the ability of the RCL to identify elbow injury.
