[Risk of chromosomal pathology in fetus with abnormal umbilical artery flowmetry]. / Rischio di cromosomopatie in feti con alterazioni flussimetriche dell'arteria ombelicale.

BACKGROUND: Goal of this study is to consider the incidence of chromosomal abnormalities in fetuses by velocimetry abnormalities. METHODS: The author select 64 pregnancies by velocimetry abnormalities of umbilical artery diastolic flow (ARED: Absent or Reverse end Diastolic Flow). RESULTS: The fetal cariotype from amniociti or from umbilical blood at delivery moment is resulted abnormal in 5 cases. Fetal-maternal risk factors of chromosomopaties are: malformations; fetal growth retardation; maternal age > or = 35. CONCLUSIONS: Other studies and other results are necessary for this discussion.

[Usefulness of ultrasonography of the cervical canal in the screening of pregnant women at risk of premature labor]. / Utilità dello studio ecografico del canale cervicale nello screening delle gestanti a rischio di parto pretermine.

BACKGROUND: Goal of the study is to evaluate the utility of cervical sonography in the second quarter as screening of pregnancies with risk of preterm labor. METHODS: A.A. evaluate, by transvaginal sonography (TVS) of the uterine cervix, 75 pregnancies with history of preterm labor and 25 with risk of preterm labor between XXIV and XXXIII week of pregnancy. The uterine cervix length < 40 mm and width > 5 mm, funneling were pathological and predictive factors of preterm labor. RESULTS: Eighty-five percent of pregnancies that have, at sonography TVG, abnormal values of length and width of uterine cervix, delivered before XXXVI week. CONCLUSIONS: These results confirm the importance of the high frequency ultrasonography transvaginal, TVS, for its predictive value and for treatment in pregnancies with risk of preterm labor.

[Prevention of gestational hypertension with calcium, linoleic acid, mono and polyunsaturated fatty acid supplements]. / Calcio, acido linoleico e acidi grassi mono e polinsaturi nella prevenzione della ipertensione gestazionale.

BACKGROUND: The aim of this study was to evaluate the benefits of calcium, linoleic acid and mono- and polyunsaturated fatty acids in the prevention of gestational hypertension. METHODS: Between January 1999 and June 2000, 65 primagravidas with a risk of gestational hypertension between the 20th and 24th week of pregnancy were recruited using Doppler velocimetry of the uterine arteries and Holter 24-h pressure monitoring. Patients with diabetes, hypertensive gestosis and previous renal pathologies were excluded. The patients were divided into 2 unequal groups: Group A (40 patients) was treated with calcium, linoleic acid, and mono and polyunsaturated fatty acid supplements; Group B (25 patients) received no treatment. The patients in both groups underwent Doppler velocimetry of the uterine arteries and Holter pressure monitoring at 28-30-32-35 weeks of gestation. RESULTS: Calcium linoleic acid and mono and polyunsaturated fatty acid supplements were effective in significantly reducing the incidence of gestational hypertension (p>0.05); in fact 90% of patients in Group A underwent a physiological evolution of pregnancy compared to only 10% affected by gestational hypertension. In the control group the incidence of this pathology was much higher (32%). CONCLUSIONS: The authors conclude that calcium linoleic acid and mono and polyunsaturated fatty acid supplements are useful and effective in the prevention of gestational hypertension in women at risk for this pathology.

The importance of high resolution transvaginal sonography in early screening of fetal chromosomal pathology.

BACKGROUND: Continuous technological improvement made in the field of ultrasound applied to obstetric diagnostics (see tridimensional sonography) has contributed to a better and non-invasive early diagnosis of fetal malformations. METHODS: To evaluate the usefulness of ultrasound in detecting early chromosomal derangements, the authors carried out a high resolution transvaginal sonography (> 6.5 mHz), between the 10th and 14th week of gestational age, on 650 pregnant women at risk for congenital anomalies and afterwards they were subjected to early amniocentesis RESULTS: Sonographic fetal anomalies were seen in 61 cases (9.3%). The incidence of fetal anomalies in these cases was 52.5%. Trisomies and number of sexual chromosome anomalies were seen, especially, in the cases of cystic septated hygroma and fetal nuchal translucency > or = 3 mm which are the most frequent sonographic markers of chromosomopathies. CONCLUSIONS: Although further studies are necessary, these findings suggest the usefulness of high resolution transvaginal sonography for the early screening of chromosomopathies.

[Prevention of vaginal prolapse in patients undergoing abdominal hysterectomy]. / La prevenzione del prolasso vaginale in pazienti sottoposte a laparoisterectomia.

BACKGROUND: In our study we evaluate a personally developed surgical technique that, when used for abdominal hysterectomy, helps prevent posthysterectomy vaginal wall prolapse. METHODS: We have used this modified surgical procedure in 244 consecutive abdominal hysterectomies performed from January 1973 through December 1986, compared with 133 abdominal hysterectomies performed without this new procedure. Patients returned monthly and annually thereafter for follow-up. The longest follow-up period to date is 12 years. RESULTS: Of the 244 patients in our study followed up for 12 years, 234 (95.9%) retained excellent vaginal support. Vaginal wall prolapse occurred in 10 patients (4.1%), and it was asymptomatic prolapse, with the vaginal wall descending less than halfway from the ischial spines to the hymen. CONCLUSIONS: This procedure is an acceptable method to help prevent posthysterectomy vaginal wall prolapse.
