Unlabelled: We report the presence of iopromide in the bowel and urine of a preterm infant, born 10 days after intravenous administration of the nonionic monomer to his mother. Excessive urinary iodine excretion and borderline hyperthyrotropinaemia were observed in the infant. Moreover, crossing of the fetal blood-brain barrier was demonstrated by detection of the angiographic material in CSF and thus direct fetal neurotoxic effects cannot be excluded.
Conclusion: These widely used contrast media may cross the placenta and accumulate in various fetal tissues in significant amounts causing possible neonatal toxicity. Therefore the perinatal safety of these diagnostic agents should at least be questioned.

L-Mimosine is the main active component of the plant Leucaena leucocephala. Due to its metal-chelating mechanism, it interacts with various metabolic pathways in living organisms, making it a potential pharmacological target, although it also leads to toxicity. The present study aimed to investigate the transplacental passage of L-mimosine and its effects on embryofetal development.

Gestational pemphigoid is a rare, autoimmune, subepidermal bullous disease with an incidence of 1 in 50,000 pregnancies, displaying itself through pruritic erythema and urticarial papules and plaques that evolve into tense bullae. Histopathological findings consist of subepidermal vesicles with perivascular eosinophils and lymphocytes, and direct immunofluorescence reveals C3 complement and, more rarely, IgG in a linear band along the basement membrane. The course is usually self-limiting within 6 months after delivery but, later, can be triggered by subsequent pregnancies, menstruation, or treatment with oral contraceptives.

Medication use during pregnancy poses risks to both the mother and the fetus. These risks include an elevated potential for fetotoxicity due to placental drug transport. Nanomedicines offer a promising solution by potentially preventing trans-placental passage.
