Epilepsy and chromosomal abnormalities

BACKGROUND Many chromosomal abnormalities are associated with Central Nervous System (CNS) malformations and other neurological alterations, among which seizures and epilepsy. Some of these show a peculiar epileptic and EEG pattern. We describe some epileptic syndromes frequently reported in chromosomal disorders.

In human live births, the prevalence of a chromosome aberration is ?0.5% and, of these, 0.1–0.3% correspond to structural chromosome rearrangements such as translocations, inversions, insertions and deletions .Our proband is an infant who had died 4 hours after birth due to a variety of abno...

Effect of copper on isolated rabbit blastocysts.

The effect of copper on the electrical membrane properties of the isolated-perfused 6-day rabbit blastocyst was studied to understand changes in the intrauterine environment caused by the copper IUD. Blastocysts were perfused in an environmental chamber containing Krebs-Ringer bicarbonate with 1 mg bovine serum albumin/ml. Electrical measurements made included short-circuit current (SCC) (the...
