Forty-five patients received subcutaneous tryptorelin depot (Decapeptyl 3.75, IPSEN SpA), 41 received subcutaneous tryptorelin acetate daily (Decapeptyl 0.1 mg, IPSEN SpA) and 46 received 0.05 mg tryptorelin acetate daily from day 21 of the cycle. From day 3 of the new cycle, if the estradiol levels were < 30 pg/ml, patients received two or three ampules of gonadotropin daily. In the group receiving subcutaneous tryptorelin acetate depot, the mean number of total gonadotropin ampules was significantly higher (p < 0.05), otherwise estradiol levels and the number of oocytes retrieved, fertilized and cleaved were significantly lower (p < 0.05). Pituitary oversuppression induced by GnRH-a causes an increase in the gonadotropin requirement for assisted reproductive techniques (ART) and a reduction in the number of oocytes retrieved and fertilized. There is a high risk of oversuppression in normal-weight or underweight women, because there is greater bioavailability of the peptide, hence elevated circulating levels of GnRH-a. Thus, ovarian stimulation in ART cycles depends on many factors, not least the identification of the best GnRH-a dose.

Several pregnancy and delivery complications, mainly related to vascular and uterine rupture or to soft tissue tears, are described. A case of a full term pregnancy is reported and the clinical value of obstetrical management is discussed.

Furthermore, the behaviour of the complement (C) system was followed. Results showed that IC were low in the first trimester of normal pregnancy (25.3%) and decreased in the following trimesters, whereas they were always present in pre-eclampsia. A very significant difference (p less than 0.0001) was seen when we compared the incidence of IC in normal pregnancy at the third trimester and the pre-eclamptic patients. The follow-up study of the IC, carried out on 4 pre-eclamptic women, showed an increase in the IC levels associated with the exacerbation of the pre-eclamptic picture and a decrease after delivery. The study of complement in normal pregnancy showed a decrease in C1-INH, C1s and C1q, whereas C3, C5, C9 and the properdin factor B increased during the following weeks of gestation; CH50 did not vary excepting during the 1st trimester. In the puerperium all values increased. There was no significant difference between the serum levels of the C components in the 3rd trimester of normal pregnancy and pre-eclampsia. High levels of C3d were observed in normal pregnancy at the 3rd trimester and in pre-eclampsia. The study of this split product of C3 showed that there is activation of the C system, but, since the synthesis of the C components is increased, activation could be masked. Alloantibodies and circulating IC could be the factors responsible for this activation in normal pregnancy and in pre-eclampsia, respectively.

The data of 101 women between the 36th and 42nd week of gestation were included. The age of our patients ranged from 20 to 30 years.--For assessment of the degree of anxiety we used the STAI X-1 test (questionnaire for self-assessment of anxiety as condition and characteristically personal property, resp.). Cases of pathologic gestation were excluded by history and a carefully clinical examination. No significant correlations between the level of anxiety and fetal condition could be demonstrated. We detected only a slight tendency of decreasing heart-rate variability and increasing frequency of accelerations in the CTG, as well as an increase of active fetal movements with a raising maternal level of anxiety.

The percentages of T lymphocytes (E-rosetting and T3+ cells) were lower in cord blood than in peripheral blood (PB) from adults, while the percentage and absolute number of T6+ cells were higher in cord blood. As the sum of T4+ and T8+ cells exceeded the values of E-rosetting lymphocytes in cord blood, we suggest that immature lymphocytes with the phenotype of 'common' thymocytes (T6+, T4+, T8+) are present in cord blood of full-term newborns. Higher percentage and absolute number of B lymphocytes were detected in cord blood. More than 50% of B cells in cord blood formed rosettes with mouse erythrocytes, a surface marker of functional immaturity. Finally, cells bearing receptors for IgG-Fc fragments or C3 and expressing Ia-like and M1 antigens were uniformly increased in cord blood, suggesting higher percentages of cells of the monocytic lineage.

Histologically, neither endometrium nor cervix were involved. To date, only 2 cases of primary gastrointestinal (gastric) cancers with no metastases to the cervix, suspected by PAP-smear, have been reported in medical literature. A few more have been reported with cervical metastases. The suspicion of intraabdominal adenocarcinoma was based on the evidence of signet ring cells found in the smear with negative cervical biopsies and negative fractional curettage. A postmortem examination confirmed the absence of genital involvement. Our aim is to remind the clinician that an abnormal PAP-smear, due to non gynecological malignancies, can, on rare occasions, be observed. In order to obtain a positive cervico-vaginal PAP-smear by a non gynecologic intraabdominal exfoliating cancer, both previous literature and our case suggest peritoneal effusion to be of major importance.

The aim of this study was to evaluate prognostic factors for survival following surgical resection of brain metastases in patients with ovarian carcinoma. A retrospective chart review was conducted on 22 patients who had been submitted to neurosurgical resection of a solitary brain metastasis from ovarian carcinoma. Eighteen lesions were cerebral, 4 were cerebellar. CNS was the only site of disease in 9 patients, 9 patients had CNS and abdominopelvic disease, and 4 also had concomitant extraperitoneal dissemination. Following surgery, 17 received whole-brain radiotherapy and 5 received systemic chemotherapy. Median survival from diagnosis of cerebral metastasis for the entire series was 16 months (range, 4-41 months). Extracranial disease at the time of CNS metastasis and time interval between diagnosis of ovarian cancer and CNS involvement manifestation were the only factors significantly affecting survival. Neurosurgical resection of brain metastasis from ovarian carcinoma is indicated in solitary lesions in the absence of systemic disease. The role of chemotherapy and stereotactic radiosurgery should be investigated.

Out of 105 patients with abnormal uterine bleeding 47 showed structural abnormalities. Comparative analysis between hysteroscopic and histological results in 58 women without gross abnormalities has been performed in order to verify sensitivity and specificity of hysteroscopy in the diagnosis of endometrial hyperplasia. Specificity of hysteroscopy in diagnosing endometrial hyperplasia was 84.7% while sensitivity resulted to be 80%. Women with abnormal uterine bleeding and normal uterine cavity has a low rate (3.4%) of false negative endometrial hyperplasia. On the contrary findings of endometrial hyperplasia at hysteroscopy has a high incidence of false positive (25.8%). In conclusion, abnormal uterine bleeding could cause an increased thickness in endometrium, appearing as hyperplasia on hysteroscopic examination.
