A male patient with aphallia, anal stenosis, tetralogy of Fallot, multiple vertebral anomalies including sacral agenesis and central nervous system (CNS) malformations was born after a pregnancy complicated by poorly controlled maternal diabetes. Aphallia is an extremely rare abnormality and can be part of the urorectal septum malformation sequence (URSMS). While aphallia has not been reported in infants of diabetic mothers, urogenital malformations are known to occur with increased frequency. Two female products of pregnancies complicated by diabetes presented with multiple malformations including anal atresia and recto-vaginal fistula consistent with the diagnosis of URSMS. The three patients share CNS, cardiac, and vertebral anomalies, abnormalities secondary to abnormal blastogenesis and characteristic of diabetic embryopathy. URSMS is also caused by abnormal blastogenesis. Therefore, this particular malformation should be viewed in the context of the multiple blastogenetic abnormalities in the cases reported here. The overlap of findings of URSMS in our cases with other abnormalities of blastogenesis, such as VATER association or sacral agenesis is not surprising, as these associations are known to lack clear diagnostic boundaries.

Eicosanoids are highly active lipid mediators in physiologic and pathologic processes, with their effects ranging from cytoprotection and vasoactivity to modulation of inflammatory and proliferative reactions. Generation of eicosanoids can be affected by changes in the pools of their precursors, the long-chain polyunsaturated fatty acids (LCPUFA). Thus, dietary interventions such as supplementation of infant formula with specific n-3 and n-6 LCPUFA will alter formation as well as activity of the eicosanoids produced. This report summarizes the results and discussion of the workshop on "Eicosanoids and Polyunsaturated Fatty Acids in Infants." The intention of the workshop organizers was to give an overview of the role of eicosanoids in physiological and pathophysiological processes in infants, to discuss the implications that an increased n-3 and n-6 LCPUFA intake may have on eicosanoid generation, and to point out open questions and controversies for future research.
