Sir.—I read with interest the articles by Kenney et al1 and Hersh et al2 as well as the editorial by Hoyme,3 all of which were related to the association (or lack of association) between supernumerary nipples and renal anomalies. I would like to point out that Kenney et al misquoted an article by me and my colleagues4 on the same topic published in AJDC four years ago. Our population consisted of Israeli (not American) neonates, and we did perform renal ultrasound examinations (not solely physical examinations) in 11 neonates.
As Dr Hoyme pointed out, the study design was eminently different in the articles by Kenney et al and Hersh et al; in the former report, term neonates were studied; in the latter report, dysmorphic children. Both studies were conducted with American children, and the results were diametrically opposed.
I would like to draw a parallel
