Insight into epileptic and physiological déjà vu: from a multicentric cohort study

BACKGROUND AND PURPOSE

The presence of a continuum between physiological déjà vu (DV) and epileptic DV is still not known as well as epidemiological data in the Italian population. The aim was to identify the epidemiological distribution of DV in Italy, and secondly to look for specific features of DV able to discriminate between epileptic and non-epileptic DV.

METHODS

In all, 1000 individuals, 543 healthy controls (C) (313 women; age 40 ± 15 years) and 457 patients with epilepsy (E) (260 women; age 39 ± 14 years), were prospectively recruited from 10 outpatient neurological clinics throughout Italy. All populations were screened using the Italian Inventory for Déjà Vu Experiences Assessment (I-IDEA) test and E and pairwise C underwent a comprehensive epilepsy interview.

RESULTS

Of E, 69% stated that they experienced 'recognition' and 13.2% reported that this feeling occurred from a few times a month to at least weekly (versus 7.7% of the control group). Furthermore, a greater percentage of E (6.8% vs. 2.2%) reported that from a few times a month to at least weekly they felt that it seemed as though everything around was not real. In E, the feeling of recognition raised fright (22.3% vs. 13.2%) and a sense of oppression (19.4% vs. 9.4%). A fifth of E felt recognition during epileptic seizures.

CONCLUSION

Only E regardless of aetiology firmly answered that they had the feeling of recognition during an epileptic seizure; thus question 14 of the I-IDEA test part 2 discriminated E from C. Paranormal activity, remembering dreams and travel frequency were mostly correlated to DV in E suggesting that the visual-memory network might be involved in epileptic DV.

Short gonadotropin-releasing hormone agonist versus flexible antagonist versus clomiphene citrate regimens in poor responders undergoing in vitro fertilization: a randomized controlled trial

OBJECTIVE

Poor responders represent a frustrating condition for couples undergoing IVF and clinicians, and their treatment remains disputed. To assess the efficacy and the most suitable protocol, we conducted a randomized controlled trial comparing three different protocols of ovarian stimulation in poor responder women: clomiphene citrate (CC) plus a high dose of gonadotropins and GnRH antagonist, flexible GnRH antagonist protocol and a short GnRH agonist protocol.

PATIENTS AND METHODS

Between July 2014 and December 2015 we enrolled 250 poor responders in a previous IVF cycle at least 3 months before. We divided into three groups: group A, 68 women treated with clomiphene citrate and FSH plus antagonist; Group B, 71 patients treated with FSH plus antagonist; Group C, 75 patients treated with FSH plus GnRH agonist.

RESULTS

The GnRH agonist protocol showed a significantly higher pregnancy rate (29.3% vs. 5.9% vs. 14.1% respectively) than the clomiphene and the GnRH antagonist protocol, number of mature oocytes collected, estradiol levels and endometrial thickness. The cost of medications for each baby born was lower for the GnRH agonist protocol than for the others; the implantation rate was significantly lower in the clomiphene group (4.8%) than in the GnRH antagonist group (9.3%) and the GnRH agonist groups (19.2%). No significant differences emerged for total FSH administered, days of stimulation, numbers of oocytes retrieved and embryos transferred.

CONCLUSIONS

This study demonstrates that short GnRH agonist protocol should be the first choice in poor responders; instead, clomiphene citrate should be avoided due to its very low success rate and high costs.
