Oral communication abstractsprovided clinically/prognostically important information in five cases and additional clinically irrelevant information in four. In the former group, the ultrasound diagnoses were: MCM + inferior vermis defect (MRI: isolated MCM), hydrocephalus + partial ACC (MRI: hydrocephalus), borderline ventriculomegaly + craniosynostosis + hemimegalencephaly (MRI: borderline ventriculomegaly), hypoplasia of the CC splenium (MRI: normal CC) and corpus callosum lipoma (MRI: + lissencephaly). Overall, the prognosis of the lesion was changed by the MRI examination in 5/92 cases (5.4%), while it increased the confidence of the diagnosis in 21/92 cases (22.8%). Conclusions: Expert neurosonography is able to reach a conclusive diagnosis in most CNS abnormalities referred to a tertiary center. The use of MRI as a second-line diagnostic procedure has a specific place in the evaluation of selected fetal anomalies, following specific queries raised by the expert neurosonologist.

The intrinsic chemistry of imidazolium‐based room‐temperature ionic liquids, related to the acidity of the C‐2 imidazolium cation, can be modified via cathodic cleavage of the C‐2/hydrogen bond. N‐Heterocyclic carbenes, electrogenerated by electrolysis of imidazolium‐based room‐temperature ionic liquids, are stable bases that are strong enough to deprotonate bromoamides 1a–k yielding the azetidin‐2‐one ring via C‐3/C4 bond formation. The electrosynthesis of β‐lactams 2a–k has been achieved under mild conditions, elevated yields and avoiding the use of toxic, volatile, molecular solvents.
