Drugs of the Benzodiazepine family are among the most frequently prescribed in France. Since anxiety disorders, for which these substances are mostly indicated, affect 10% of pregnant women, it is very likely that such a treatment could expose many foetuses to BZD during the first three Months of pregnancy. We know that the teratologic effect is not necessarily based on dose rate, but that it is associated with fetal drug exposure during the first 12 weeks of gestation, when organ formation occurs. ⋯ Step 4: similarly, the lorazepam/anal atresia finding was upheld when the analysis was restricted to the 262 malformed infants exposed to BZDs in utero. Six cases of anal atresia were found among all newborns exposed to BZD in utero, and five of them were exposed to lorazepam, representing a hypothesis to be tested in further. We are not aware of other reports of this association, and it should be regarded as preliminary until confirmed in other data sets.

Surgery can be proposed for some patients affected by psychiatric diseases such as severe, disabling and refractory affective disorders (depression), OCD and chronic anxiety states. It can be performed after a period of evolution of minimum 5 Years and after all other classical treatments have failed. For the last Years, different stereotactic techniques have been used: capsulotomy, cingulotomy, subcaudate tractotomy and limbic leukotomy, performed by radiofrequency thermolesions or radiosurgery (g rays). ⋯ Although psychosurgery is still controversial from an ethical view point, this treatment appears to be an ultimate solution for these severe disabled patients. Psychosurgery is a safe and relatively effective treatment which should be carried out by an expert multidisciplinary team in these disorders; surgery should be considered as part of an entire treatment program including an appropriate psychiatric rehabilitation part. Research in this field is currently focused on MRI-guided basal ganglia stimulation techniques which would allow to target specific structures in a reversible way.
