We present two neonates with nasal obstruction because of anterior choanal stenosis (congenital nasal pyriform aperture stenosis). An associated single maxillary central incisor was also shown on computed tomography imaging in the neonatal period. These midline anomalies are recognized minimal manifestations (microforms) of holoprosencephaly. We describe their neonatal investigation, multidisciplinary management and clinical course.

Bladder catheterization is a common technique employed in obtaining urine for culture, monitoring urine output and for diagnostic radiological procedures. We present two cases of knot formation in male infants catheterized with a 5 gauge feeding tube. We discuss avoidance, recognition and management of this complication.
