Pediatr Radiol 2018 Dec 13. Epub 2018 Dec 13.

Department of Diagnostic Radiology, Division of Pediatric Radiology,, Children's Hospital Colorado,, 13123 East 16th Ave., Mailbox B-463,, Aurora, CO, 80045, USA.

The term cloacal malformation is commonly used to describe the classic cloacal malformation where there is a single common urogenital and intestinal channel located at the expected site of the urethra. There is, however, a spectrum of cloacal abnormalities that differ from this classic type and are less well discussed in the radiologic and surgical literature. The aim of this pictorial essay is to familiarize radiologists with the anatomy, appropriate terminology and key prenatal imaging findings that differentiate the six entities that constitute the spectrum of cloacal abnormalities.

Am J Clin Nutr 2018 Dec;108(6):1357-1368

School of Nutrition Sciences, University of Ottawa, Ottawa, Ontario, Canada.

The Government of Canada and the Society of Obstetricians and Gynaecologists of Canada both recommend a daily multivitamin supplement containing 400 µg folic acid (FA) for the primary prevention of neural tube defects among low-risk women from before conception and throughout lactation. Prenatal supplements marketed and prescribed in Canada typically exceed the recommended dose, usually providing ≥1000 µg FA/d. This high daily dose, coupled with staple-food FA fortification, has resulted in the observation of very high blood folate concentrations among reproductive-aged women consuming FA-containing supplements.
