Prolonged survival of stage IV malignant mixed Müllerian tumor of the ovary after carboplatin, mesna, ifosfamide, and cis-platin chemotherapy: case report.

Malignant mixed müllerian tumors (MMMT) of the ovary are rare, aggressive and rapidly progressive tumors. According to the available literature, the presence of metastatic disease rarely permits long term survival. We report on a 64-year old patient with stage IV ovarian MMMT who achieved a surgically-documented complete response (CR) after 6 cycles of carboplatin, mesna, ifosfamide, cis-platin. Pelvic recurrence was diagnosed 14 months later; the patient received 6 cycles of the same regimen used as first-line chemotherapy which resulted in a second complete response lasting for 4 months. The patient died 37 months after initial diagnosis due to intestinal occlusion. In the current case Ca 125 was significantly increased at clinical presentation of disease but not at the time of recurrence.

[Angiogenesis and endometrial carcinoma. Correlations with blood flow analysis by transvaginal color Doppler ultrasonography].

Neoangiogenesis is a basic event in the evolution and spread of several solid neoplasms. Angiogenesis is an active phenomenon in physiological endometrium in the reproductive age and seems to disappear in postmenopause. Endometrial hyperplasia and adenocarcinoma are associated with signs of angiogenetic activity. The factors promoting angiogenesis in endometrial carcinoma are still unknown. Similarly it is not possible to recognize which endometrial carcinoma is potentially angiogenetic, but a relationship between angiogenesis and early metastatic spread has been established. Angiogenesis is definitely a late component of invasive tumour, but an early angiogenetic behaviour of some neoplastic clones, that could be a main prognostic factor for endometrial carcinoma is hypothesized.

Hemangioma of the ovary. A case report.

BACKGROUND: Ovarian hemangioma is extremely rare. CASE: We report a case of a 32-year-old woman who complained of pelvic pain due to a large right adnexal mass. On color Doppler sonography the mass showed very rich and complex vascularity, with prominent blood flow. A 10 x 8-cm hemangioma of the right ovary was resected. CONCLUSION: Hemangiomas should be considered when a richly vascularized tumor with prominent blood flow is detected on color Doppler sonography or magnetic resonance imaging.

Non-Hodgkin lymphoma in a gynecologic service. A report of three cases.

Primary lymphoma arising in female genital tract organs is extremely rare. We report three cases of non-Hodgkin lymphoma which were encountered during a four-year period at our gynecologic department. One patient presented with an inguinal mass; another had a primary lymphoma of the vagina and the third had massive pelvic and para-aortic lymphomatous involvement. The gynecologists should be aware that, although rarely, lymphomas may arise in the genital tract, and that a massive involvement of inguinal, pelvic or para-aortic nodes may be related to a lymphoproliferative disease.

Astroglia-microvessel relationship in the developing human telencephalon.

The telencephalon of 12 and 18 week-old human foetuses was examined for evidence of astroglia-microvessel relationship. Immature astroglia cells (radial glia and astroblasts) and astrocytes were immunostained using antibodies to the cytoskeletal proteins vimentin (VIM) and glial fibrillary acidic protein (GFAP). The microvessels were detected using an antibody to the blood-brain barrier (BBB)-specific glucose transporter GLUT1. Two extracellular matrix (ECM) glycoproteins, laminin (LM), an endothelial-derived molecule, and tenascin-C (TN-C), a glia-derived molecule, were also analyzed. In the two stages examined, VIM- and GFAP-positive fibers of the radial glia establish close relationships with the radial and periventricular microvessels, which are GLUT1-positive and lined by an LM-positive basal lamina-like matrix. At the 18th week, also radial glia transitional forms and immature astrocytes exhibit extensive contacts with the microvasculature. A TN-C-rich ECM is revealed around the vascular plexus of ventricular zones at the 12th week, and around the newly growing radial microvessels and the microvessel branching sites at the 18th week. The observations taken as a whole, suggest that during the telencephalon morphogenesis the immature astroglia cells play a role in the early establishment of the distribution pattern of the neural microvessels and in their growth and maturation.

[Maternal viral and gestational risk factors in vertical transmission of HIV-1 infection].

BACKGROUND: Several risk factors are related to vertical transfer of HIV-1 infection, but the influence of each one separately is controversial. Various risk factors have been evaluated altogether and separately, in order to find a single condition, that is, early in pregnancy predictive of fetal infection. METHODS: A prospective, observational study has been carried out during the period January 1992-January 1997, at the Centre for infectious diseases in pregnancy, University Hospital of Bari, a tertiary reference setting. Forty-four HIV-1 infected mothers have been recruited in early pregnancy, to be followed-up until delivery. Neonates have been evaluated in the Pediatric Department of the same hospital until 18 months of age. Maternal risk factors, such as age, infection in the partner, mode of acquisition of HIV-1, drug addition, life-style and risky behaviour as well as stage of disease, immunological status and antiviral treatment were considered. Obstetrical factors, too, (parity, preterm delivery, rupture of membranes, duration of labour and mode of delivery) were taken into account. Data were analyzed according to Fisher exact test and Draper and Smith multivariate analysis. RESULTS: Thirty cases (9 inadequate for follow-up, 4 ongoing pregnancies, 1 perinatal death before ascertainment of infection) were evaluated for final results. The overall transmission rate was 13.3%. Single factors significantly related to transmission were stage of disease (p < 0.01), mode of maternal infection (p < 0.03) and maternal HCV infection (p < 0.04). Multivariate analysis has shown the stage of disease to be the only positively-related risk-factor. CONCLUSIONS: The data identify a sub-group among HIV-1 infected women, where the more sustained rate of vertical transmission is associated with risky behaviour, as determined both by drug addiction and positivity for another sexually transmitted disease. Maternal compromise and immunological status are, however, the highest-risk conditions for delivering a HIV-1 infected baby.

Serous papillary cystadenoma of borderline malignancy of the broad ligament.

Serous papillary cystadenoma of borderline malignancy arising in the broad ligament is extremely rare. We report the case of a 28-year-old female with a cystic mass in the broad ligament, who underwent complete excision of the mass, right salpingo-oophorectomy, omentectomy and multiple peritoneal biopsies. Pathology showed a serous papillary cystadenoma of borderline malignancy of the broad ligament, without peritoneal and omental involvement. A review of the literature about this rare pathologic condition is reported.

A vaginoscopic approach to reduce the pain of office hysteroscopy.

We developed a new approach to diagnostic hysteroscopy that reduces patient discomfort and increases the possible applications of hysteroscopy. Between February 1992 and March 1996, 1200 hysteroscopies were performed at our institution. Of these, the last 680 were done using the vaginoscopic approach without preselection. Discomfort was reduced in all patients, including those with moderate stenosis of the internal cervical os. Vaginoscopy is easy to perform and incurs no additional cost for the patient. It is ideal for office hysteroscopy and in patients who otherwise might require general anesthesia, such as virgins and older women with somewhat stenotic vaginas.

Transvaginal color Doppler sonography in predicting the response to chemotherapy in advanced cervical cancer.

The role of Doppler ultrasonography in the diagnosis of advanced cervical cancer continues to be controversial. This study was designed to assess the clinical value of the technique in terms of predicting the response to chemotherapy in patients with advanced cervical cancer. Twenty-three patients with cancer of the cervix (FIGO stages Ib bulky-IIIb) and 20 healthy women underwent transvaginal color Doppler assessment of the uterine arteries (both ascending and descending branches) and the intracervical vessels. Statistical analysis was performed by Student's t test for paired and unpaired data. The intracervical vessels were the only site to show significant differences both in the resistance and in velocity parameters. A subgroup of 14 patients, scheduled for neoadjuvant chemotherapy, were evaluated before and at the completion of treatment. A significant increase in resistance and pulsatility index values and a decrease in peak systolic velocity were observed in the ten patients who responded to chemotherapy. Preliminary results of our study suggest that Doppler parameters can be clinically useful in the evaluation of the response to neoadjuvant chemotherapy. More patients, sampled in a prospective way in order to increase the number of non-responders, would be necessary to assess the possible role of Doppler ultrasound in predicting which patients will respond to chemotherapy.

Central nervous system involvement secondary to metastatic mixed müllerian tumor of the uterus.

The central nervous system is traditionally considered an uncommon site for metastatic disease from female genital tract tumors. We report the case of a 48-year-old woman with malignant mixed müllerian tumor of the uterus, who developed spinal cord compression by epidural metastasis a few days after the diagnosis of the uterine malignancy. Emergency decompressive laminectomy was performed and a good recovery of the neurological function was achieved. In the following days, while submitted to extensive staging for the uterine malignancy, the patient complained of headache, confusion and visual disturbance. CT scan revealed multiple brain metastases. No other site of metastatic disease could be detected. The patient refused any further treatment and died 1 month later from progressive cerebral disease. Attention should be paid to the possibility of unusual distant metastases associated to uterine sarcoma in order to treat these patients promptly.

Transvaginal color Doppler ultrasound for monitoring the response to neoadjuvant chemotherapy in advanced cervical cancer.

BACKGROUND: To evaluate the role of transvaginal color Doppler ultrasound in monitoring the response to neoadjuvant chemotherapy in patients with locally-advanced cervical cancer. METHODS: Fourteen patients with locally-advanced cervical cancer, scheduled for neoadjuvant chemotherapy, were investigated with transvaginal color Doppler ultrasonography before and at the completion of chemotherapy in order to study hemodynamic changes in cervical and intratumoral vessels. Twenty healthy women matched for age and parity served as a control group. Statistical analysis was performed with Student's t test for paired data. RESULTS: Statistically different blood flow recording between patients with cervical cancer and healthy controls could be observed only in intratumoral vessels. A significant increase of RI and PI values, recorded in both cervical artery and intratumoral vessels, have been observed in the group of patients responding to neoadjuvant chemotherapy. In patients with stable disease at the completion of chemotherapy, flow characteristics did not change significantly. CONCLUSION: Preliminary results of our study suggest that transvaginal color Doppler ultrasound evaluation of flow characteristics in the cervical and intratumoral vessels might be useful in monitoring the response to neoadjuvant chemotherapy in patients with invasive cervical cancer.

Neutropenia in neonates delivered of women with pre-eclampsia.

OBJECTIVE: To show that neutrophil counts are decreased in neonates born of mothers with pre-eclampsia and that pre-eclampsia itself is an independent risk factor for perinatal neutropenia. METHODS: In a tertiary referral centre two groups of patients at high risk to have a neonate with neutropenia. All patients were delivered by elective caesarean section, group 1 because of pre-eclampsia, group 2 because of idiopathic fetal growth restriction. RESULTS: Neutrophil counts were significantly lower in infants of group 1 compared to group 2 and this difference was still present if the sub-group of less premature neonates (> 32 weeks of gestation) was considered. The rate of infections was also raised in the newborns of hypertensive mothers. CONCLUSION: Pre-eclampsia of the mother is an independent risk factor for neutropenia and infections in premature newborns. Early detection and prophylactic treatment of this high risk group of infants are probably necessary.

Fibromatosis of the female pelvis.

BACKGROUND AND AIMS: Desmoid tumour is a rare entity characterized by benign proliferation of fibroblasts. Although non malignant, this tumour can be life-threatening due to its invasive property and high recurrence rate. MATERIAL AND METHODS: We report a case of pelvic fibromatosis whereby the tumour was completely resected without sacrificing organs or major vessels. RESULTS: Thirty months after surgery the patient is asymptomatic, without any sign of recurrent disease. CONCLUSIONS: Radical surgery represents the main primary treatment for pelvic fibromatosis. The other available therapeutic options are discussed.

Lipoperoxidation and antioxidant enzymes activity in pregnancy complicated with hypertension.

OBJECTIVE: To assess maternal circulating levels of lipid peroxidation breakdown products and antioxidant enzymes activity in pregnancies complicated with hypertension. STUDY DESIGN: Ten women with uncomplicated pregnancies and nine women with hypertension antedating pregnancy were prospectively sampled. Eight women, who had developed preeclampsia, were also cross-sectionally included. Twenty healthy non pregnant volunteers were the control group. Thiobarbituric acid reactive substances (TBA-RS), as lipid peroxidation products, and the activity of catalase (CAT), glutathione peroxidase (GPX) and superoxide dismutase (SOD), as antioxidant enzymes, were assayed in red blood cell hemolysates. A prooxidant/antioxidant (P/A) ratio (TBA-RS/CAT + GPX + SOD) was determined from the mean value of the volunteers. RESULTS: In women with chronic hypertension, TBA-RS levels were higher than those in normal pregnant women, whereas antioxidant enzymes activities were either stable or decreased. Therefore the P/A ratio was progressively lower in the second and third trimester. Similar result were found in patients with preeclampsia. CONCLUSIONS: Normal gestation induces an increase of lipid peroxidation products, whereas antioxidant activity seems stable. In pregnancies complicated by chronic hypertension, a deficiency of the oxidative system balance is detectable, which consistently progresses in the second and third trimester, strongly suggesting a failure of the protective mechanisms.

Pathological significance of first-trimester fetal nuchal oedema.

The pathological mechanism that causes the transient phenomenon sonographically defined as "nuchal translucency' is still poorly understood. Seven pregnancies in which the fetuses clearly presented this ultrasonic sign at 10-14 weeks' gestation were terminated because of an abnormal fetal karyotype. The pathological specimens, compared by morphometric analysis with normal fetuses of the same gestational age, showed oedema and dilatation of lymphatic capillary vessels. No particular relationship was found with any structural abnormality. We speculate that nuchal oedema is a transient non-specific phenomenon which is probably related to an early disarrangement of lymphatic connections.
