[The significance of screening tests for aneuploidies in populations at low and high maternal-age-related risk]. / Il significato dei test di screening per le aneuploidie in popolazione a basso e alto rischio per età.

AIM: The aim of this study was to evaluate the validity of the triple test and the screen test in maternal populations at low and high maternal-age-related risk for fetal aneuploidy. METHODS: As a whole, 9,680 pregnant women at low risk and 627 at high risk underwent the triple test; 2,780 pregnant women at low risk and 408 at high risk underwent the screen or combined test; sensitivity, specificity, false positives and detection rate were compared between populations using Student's t-test. RESULTS: The triple test showed a detection rate of 75% in the low and 83.3% in the high risk population with a difference (P<0.003) for detection of trisomies 21 and 18 between the 2 populations; the screen test had a detection rates of 100% and 90% in the 2 populations, respectively, with a difference (P<0.005) between the 2 tests. CONCLUSIONS: Both tests are reliable for screening aneuploidies in the low risk population, the screen test having better performance; in the high risk population, the number of invasive procedures can be reduced by 78% with the triple test and by 84% with the screen test.

[Treatment of neurovegetative menopausal symptoms with a phytotherapeutic agent]. / Trattamento dei disturbi neurovegetativi della donna in menopausa con un preparato fitoterapico.

BACKGROUND: Menopausal symptoms include hot flushes, insomnia, nocturnal sweating, dizziness, headaches and palpitations. These symptoms reflect adaptation of the body to estrogen deprivation which affects various central neurotransmitters. METHODS: In this study, the efficacy has been tested of a plant product based on extracts of the leaves of Salvia officinalis (sage) and Medicago sativa (alfalfa) in the treatment of hot flushes in 30 menopausal women with these symptoms. RESULTS: Hot flushes and night sweating completely disappeared in 20 women: four women showed good improvement and the other six showed a reduction in symptoms. GnRH and TRH tests were performed in 8 women to evaluate TSH and Prl responses before and after 3 months of therapy. The plants product induced a significant increase in Prl and TSH response to TRH. Basal levels of estradiol, LH, FSH, Prl and TSH were unchanged. CONCLUSIONS: The product seams to have a central slight antidopaminergic action without side effects and is an effective agent in the treatment of menopausal symptoms.
