[Essential thrombocythemia in pregnancy. A case report and general considerations].

Essential thrombocythemia is a rare disease of unknown etiology characterized by an abnormal increase in the platelet count which cannot be explained by other identifiable causes such as malignancy, infection, chronic inflammatory diseases or other myeloproliferative disorders. It rarely affects people less than 50 years of age and may be associated with hemorrhagic or thrombotic tendencies. A care of pregnancy complicated by essential thrombocythemia treated with aspirin, antiaggregating agent, throughout pregnancy and with hydroxyurea, a platelet lowering drug is reported. Also examine are some pathogenetic and therapeutic aspects of the thrombotic tendency secondary to elevated platelet count in pregnancy.

[The role of transvaginal ultrasonography in the screening of ovarian tumors].

BACKGROUND: From January 1992 to March 1996, 1987 women underwent vaginal sonography screening, at the Department of Obstetrics and Gynaecology of the II Faculty of Medicine and Surgery "Federico II" in Naples. This mass screening aimed at early diagnosis of ovarian cancer. METHODS: Patients included in this investigations were all asymptomatic and had no pelvic abnormalities. Each ovary was measured in three planes and ovarian volume was calculated using the prolate ellipsoid formula. In premenopausal women, ovaries were normal if their volume was of > or = 18 cm3 and if they were hypoechogenic or anechogenic. In postmenopausal women a normal ovary was defined as having a volume of > or = 8 cm3 and a uniformly hypogenic internal structure. RESULTS AND CONCLUSIONS: In thirty-five premenopausal women was detected an abnormal volume of the ovaries. Forty-six postmenopausal women had abnormal vaginal sonograms. In this investigations vaginal sonography has permitted the detection of about 4.88% ovarian tumors in asymptomatic women, so that, it can be considered a more accurate and direment screening method for ovarian cancer than abdominal sonography.

[Changes in fetal karyotype in non-immune hydrops fetalis].

BACKGROUND AND METHODS: Among the pregnant patients who underwent an amniocentesis at our department of prenatal diagnosis (Division of Gynecology and Obstetrics of the University "Federico II" in Naples) from 1989 to 1996, 16 patients were affected by non-immune hydrops faetalis associated with chromosomal diseases. RESULTS: The karyotype test revealed at an ultrasound exam of the fetus that 11 cases were affected by trisomy 21, 4 cases by Turner syndrome and one case by trisomy 18. This study took into consideration all the pathogenetic factors and the diagnostic problems of non-immune hydrops faetalis in fetus affected by associated chromosomal associated anomalies. CONCLUSIONS: Since the incidence of the chromosomal anomalies on fetus affected by non-immune hydrops foetal is was very high, there was the necessity to carry out a routine karyotype test if the ultrasonography revealed anomalies of the hydrops, during the first three months of pregnancy.

[Needle aspiration of ovarian cysts. Our experience].

80 patients underwent ultrasound guided cyst puncture of ovarian cysts. Six patients were pregnant and in four of them needle aspiration was executed through the transvaginal tract. The sediment aspirated was examined by a cytologic method and when possible it was also correlated to a histological test. Technique and results have been dealt with. No relevant complication was found. Finally, the echoguided (induced) needle aspiration is a simple and safe method to treat benign ovarian cysts in fertile women. It is particularly advisable in pregnancy and in patients for whom both laparascopy and traditional surgery are not practicable.

[Ultrasonic criteria for the evaluation of placentation in twin pregnancies].

Ultrasound assessment of septum thickness is useful in twin pregnancies for predicting the type of placentation. In fact, its greater or lesser acoustic resonance distinguishes monochorionic or dichorionic pregnancies. This makes adoption of therapeutic measures more secure in the event of pathology involving only one of the two fetuses.

The morphological characteristics and ultrastructural aspects of cervical ripening induced by sulprostone.

Cervical tissue biopsies from fifteen pregnant women who were seeking a second trimester elective abortion were examined before and after sulprostone systemic administration, to evaluate the hystological and ultrastructural modifications. While light microscopy showed an increase in vascularity and a submucosal edema with an infiltration of inflammatory cells, electron microscopy pointed out a complete dissociation of collagen fibers with a large increase of basic substance constituents. These features are similar to modifications found in the ripening process at term, demonstrating that sulprostone can be useful to prime uterine cervix.

[Experience with non-immunologic hydrops fetalis].

Non-immune hydrops fetalis (NHF) has become, with the decrease in frequency of rhesus-isoimmunization during the last years, an important aspect of modern obstetrics in consideration of the increased diagnostic and therapeutic means now available. Some cases of NHF with particular etiology (viral twin-twin transfusion syndrome, malformations) are reported and the necessity of a multidisciplinary specialistic approach for the resolution of diagnostic and prognostic problems of this serious complication of pregnancy is underlined.
