Given that Sirenomelia is a very rare birth defect, epidemiological studies are scarce. The aim of this study is to evaluate prevalence, geographic clusters and time trends of sirenomelia in Argentina, using data from the National Network of Congenital Anomalies of Argentina (RENAC) from November 2009 until December 2014.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This is a descriptive study using data from the RENAC, a hospital-based surveillance system for newborns affected with major morphological congenital anomalies.

We observed a likely real increase in the initial period of our study. We used strict diagnostic criteria, excluding cases that only had clinical diagnosis of sirenomelia. Therefore, real prevalence could be even higher. This study did not show any geographic clusters. Because etiology of sirenomelia has not yet been established, studies of epidemiological features of this defect may contribute to define its causes.

First, we explored prenatal exposures in heterotaxy syndrome (cases) and Down syndrome (controls).

No differences in intoxication use during pregnancy were found between cases and controls, including smoking (28.0% vs. 22.7%; <i>p</i> = 0.40), alcohol (14.0% vs. 26.9%; <i>p</i> = 0.052), and recreational drugs (0 vs. 0.3%; <i>p</i> = 1.00). We found an association between heterotaxy syndrome and prenatal drug exposure to follitropin-alfa (5.6% vs. 1.1%; <i>p</i> = 0.04), and drugs used in nicotine dependence (3.7% vs. 0.2%; <i>p</i> = 0.02).

Our data suggest the possibility that there is an increased risk of birth defects (including renal, urological, and cardiac abnormalities) in children born among mothers taking PTU prenatally, but not for heterotaxy syndrome.
