Maternal complications after caesarean section in HIV infected women.

OBJECTIVE: To assess the intervention related risk in HIV-infected women, undergoing caesarean section (CS). SETTING: Tertiary care center for high risk obstetrics and infectious diseases in pregnancy. PATIENTS AND METHODS: Thirty-three HIV-positive women and one hundred and sixty-eight controls, cross matched for age, weight, parity, obstetrical characteristics at delivery and indication for CS, were prospectively recruited for the study. Infection related characteristics, as mode of acquisition, drug abuse, immune status and stage of disease were also recorded. Complications of the intervention were evaluated according to infectious status and risk factors. RESULTS: Post-operative complications were significantly more frequent among HIV-infected mothers. More advanced disease and maternal age were the risk factors statistically related to complications. DISCUSSION: According to our data, CS carries a higher chance of post-operative complications in HIV-infected women, these complications being also related with the severity of infection (stage and duration of the disease). Given the characteristics of the population in the study (mode of acquisition, prevalence of early stage of the disease), the rate of complication is still relatively low compared to non-western, malnourished, drug-abusers groups.

Primary peritoneal carcinoma: a report of twelve cases and a review of the literature.

Primary peritoneal carcinoma (PPC) is rare tumor histologically identical to epithelial ovarian carcinoma (EOC); it is differentiated from EOC based on the extent of gross ovarian involvement and microscopic invasion of the cortex. We report 12 cases of PPC which were diagnosed in our Department during a 9-year period. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed in 9 patients, while 3 underwent only explorative laparotomy with bilateral salpingo-oophorectomy. All patients were treated with postoperative platinum-based chemotherapy. After a median follow-up of 42 months, only 5 patients are alive without disease. PPC is a rare tumor currently managed in the same way as ovarian cancer. Primary debulking surgery and chemotherapy represent the cornerstones of treatment. Considering the limited number of patients with PPC, no definitive conclusion can be drawn concerning the prognostic factors for survival.

Endoscopic examination of the fetus in early pregnancy.

OBJECTIVE: To assess if fetal examination is feasible by endoscopy in the late first-early second trimester. SETTING: Tertiary referral center for high risk obstetrics and genetics. PATIENTS AND METHODS: Patients (total number 9) submitted to pregnancy termination for social reason (7) or for chromosomal abnormality (2) between 10 and 14 weeks of pregnancy. Visualisation of the foetus by a transabdominally introduced endoscope (19 gauge) under local anaesthesia. Step by step examination of the foetal contour and double check of the recordings by a senior Pathologist. RESULTS: Patients complained no serious discomfort. Visualisation was accomplished in all cases with ease and the images were judged satisfactory by the Pathologist. Fetal examination was found easier at 10-12 weeks of gestation rather than at 13-14 weeks. DISCUSSION: Endoscopy is a simple and well tolerated procedure, which enables precise visualization of external fetal anatomy as early as the first trimester of gestation. Therefore it can be proposed before surgical termination of pregnancy.

Predictive value of serum androstenedione basal levels on the choice of gonadotropin or laparoscopic ovarian electrocautery as ovulation induction in clomiphene citrate-resistant patients with polycystic ovary syndrome.

Therapeutic approaches to chronic anovulation from polycystic ovaries in clomiphene-resistant infertile patients are under debate. This study discusses evidence that supports the possible predictive value of serum basal level of androstenedione in the choice of the better therapy between laparoscopic ovarian electrocautery and ovulation induction. Lower androstenedione levels seem to be correlated with a better ovarian response after ovulation induction with gonadotropins, while high androstenedione levels are associated with a higher incidence of conception after laparoscopic ovarian electrocautery. Obesity does not seem to represent a hindrance to laparoscopic treatment.

[Combination of cisplatin and vinorelbin in the neoadjuvant treatment of locally advanced cervical carcinoma. Phase II study].

BACKGROUND: Aim of this phase II study is to evaluate the cytoreductive efficacy and the toxicity of a regimen consisting of cisplatin and vinorelbine as neoadjuvant chemotherapy for three cycles every 21 days in patients with locally-advanced cervical carcinoma. METHODS: Between April 1996 and December 1998, 33 untreated patients with locally-advanced cervical carcinoma received neoadjuvant chemotherapy with cisplantino 80 mg/m2 (day 1) plus vinorelbine 25 mg/m2 (day 1 and 8). Within 28 days from completion of chemotherapy patients in complete or partial response were submitted to radical hysterectomy plus pelvic lymphadenectomy. RESULTS: Twenty-six patients (79%) were submitted to radical surgery; four patients were not submitted to surgery because of poor response to treatment, two for anesthesiological contraindications and one refused surgery. The combination of cisplatin plus vinorelbine in this phase II study induced a clinical overall response rate of 90%, with 8 pathologic complete response (24%). CONCLUSIONS: The association of cisplatin and vinorelbine as neoadjuvant chemotherapy in locally-advanced cervical carcinoma showed to be safe and effective with a low cost and poor toxicity.

[Reconstructive surgery in oncological gynecology. Our experience].

BACKGROUND: Personal experience in reconstructive surgery for gynecologic oncology is reported. These techniques are playing, during last years, a leading role since it is necessary to assure a good treatment and top quality lifestyle to oncologic patients. METHODS: A retrospective study was made on 357 major surgical treatments for neoplastic disease at the IInd Clinic of Obstetrics and Gynecology, University of Bari. For each disease the technique, the length of surgery and possible complications have been reported. In total 50 reconstructive procedures on 357 surgical interventions for gynecologic neoplastic disease (14%) were made. RESULTS: There was no rate of mortality, and the complications were found only in 5 patients (10%). CONCLUSIONS: Reconstructive surgery can increase surgical radicality, improve the quality of life of the patients and reduce the postoperative complications.

Aggressive angiomyxoma of the pelvis. A case report.

Aggressive angiomyxoma is a locally mesenchymal, benign, and rare neoplasm. The vulva, perineum, and pelvis are the most common sites of involvement. The preoperative diagnosis is postulated by CT, sonography, MR image and angiography. The immunohistochemical study reveals the definitive diagnosis. The therapy is only surgical, and because of its tendency to recur locally, the excision has to be as complete as possible.

[Fetal growth restriction and insulin-like growth factors].

The insulin-like growth factors (IGFs) and their receptors are implicated in pre- and postnatal growth and development. It is believed that the alteration in their activity may contribute to intrauterine growth restriction (IUGR). The aim of this experimental study was to relate some metabolic alterations, involving insulin-like growth factor pathway, in the placenta of pregnancies complicated by intrauterine growth restriction. Placental samples were obtained from six uncomplicated pregnancies and four pregnancies complicated by IUGR. These samples were then stained by immunohistochemical technique, using monoclonal antibodies. Our data have not shown a significant difference in the IR, the Shc isoforms and Akt levels between normal and IUGR placentas. The IUGR placentas had significantly lower levels of IRS-2 expression and higher levels of p85 transcription. IGF-I receptor binds to its ligand and activates two intracellular processes mainly a Shc-mediated pro-mitotic pathway and an anti-apoptotic pathway mediated by IRS and Akt. The diminished activity of one of the two pathways may alter the mitosis/apoptosis balance. Because of the low number of samples and the knowledge about the enzymatic pathways, we have not been able to associate our data to any biological consequence. We can only demonstrate that the enzymatic differences between IUGR and controls tend to the pro-apoptotic processes. It seems to be an other in vivo aspect in favour of the placental role in the IUGR pathogenesis.

[Echographic measurement of subcutaneous adipose tissue as fetal growth index].

OBJECTIVE: To evaluate, by 3rd trimester ultrasound examination, fetal adipose tissue to predict fetal growth and birthweight. PATIENTS AND METHODS: Thirteen pregnant women (group 1) with uncomplicated pregnancy and 9 diabetic women (group 2) have been enrolled. We have examined adipose tissue at the cross sectional level of arm, thigh and abdomen and at the longitudinal sectional level of shoulder. During 3rd trimester measurements were taken at the beginning (28-32 gestational weeks), at the middle (34-38 gestational weeks) and at term (39-41 gestational weeks). At birth we recorded the skinfolds of arm, thigh and shoulder and the neonatal weight. Subsequently, by regression analyses ultrasound parameters of physiological pregnancies were correlated to skinfolds measurements at birth, while abdomen thickness was compared to birthweight. In addition, ultrasound markers of the physiological pregnancies were compared to those of diabetic pregnancies by the t-test. RESULTS: Fetal limbs examination had not a prognostic value at any gestational week. Shoulder ultrasound measurements appeared well correlated to the shoulder skinfold after birth since the 34th week. Diabetic mothers' fetuses presented much more adipose tissue than control cases, particularly of arm and thigh at 28-32 weeks, of shoulder at 34-38 weeks and in all the markers at term pregnancy. CONCLUSION: Ultrasound examination of fetal adipose tissue seems to have a predictive value for fetal growth both in physiological and diabetic pregnancy.

[Incidence of thyroid diseases in pregnant women with type I diabetes mellitus].

The interaction between pregnancy, Diabetes Mellitus and thyroid disturbance needs a particular attention. The antithyroid antibodies are more frequent in pregnant women with insulin-dependent diabetes mellitus (IDDM) than in normal pregnant women. Beside, an increased prevalence of subclinic ipotyroidism has been described in pregnant diabetic women. The object of this study is to verify if women with insulin-dependent diabetes mellitus have more probability than normal women to develop a thyroid pathology in pregnancy, in an area with sufficient iodine. Twenty-eight women have been studied: 15 with IDDM, with age 20-37 years, and 13 healthy women, with the same age. Patients were evaluated at the following time-intervals: 9-12 and 18-20 weeks' gestation, at delivery and six months after delivery. Diabetic women followed an insulinic therapy optimized for to reach a good metabolic control. All follow the patients had a thyroid ecography to evaluate thyroid volume and possible presence of nodular formation or others pathologic signs. A blood sample to assay FT3, FT4, TSH, of the antibodies Anti-Thyreoperoxidase (Anti-TPO) and Anti-Thyreoglobulin (Anti-TG). A urine specimen taken to evaluate the iodine excretion. No significant difference was observed between diabetic and normal women, for the values of TSH (p < 0.2), FT4(p < 0.7), FT3(p < 0.6). Instead a significant difference was found between the thyroid volume (p < 0.04), in the diabetic patients versus the normal women, at delivery and six months after delivery. The results of this study underline the importance of the screening of the thyroid function and morphology, in all the pregnant women and, particularly, in the diabetic patients, to find the presence of glandular alterations as early as possible.

[Prevalence and distribution of congenital cardiopathy at birth and in pregnancy termination: impact of prenatal diagnosis in 4 years of experience].

OBJECTIVE: To evaluate in two time intervals the potential impact of prenatal diagnosis on prevalence and spectrum of CHD at birth and in aborted fetuses. PATIENTS AND METHODS: At the University Hospital of Bari, south-east Italy, in the period between January 1st 1996 and December 31st 1999 a retrospective study was performed of all newborns and termination of pregnancy (TOP) beyond 18 weeks' gestation with postnatally diagnosed CHD. An antenatal fetal ultrasonic evaluation had been always performed between 18-22 weeks' gestation. The prevalence, distribution and detection rate of CHD at birth and in TOP were assessed and compared between two different periods of time (96-97 vs 98-99) to verify an eventual improvement in the prenatal diagnosis due to the learning curve and to new technologies. RESULTS: Prevalence of severe CHD in livebirths and aborted fetuses showed no significant changes between the two study periods (respectively 4.6@1000 vs 5.4@1000, at birth; 10% vs 11%, in TOP) and the same was observed as for as distribution of CHD. Maternal or fetal risk factors were found in 23% of cases of CHD at birth and in 74% of cases of CHD in aborted fetuses. The antenatal detection rate of CHD did not change between the two study periods in newborns (25% vs 27%, NS) while in aborted fetuses it was higher and showed a significant longitudinal improvement (53% vs 85%, p < 0.05), which was more evident if only selected cases were considered (56% vs 93%, p < 0.03). DISCUSSION: Our data show that gain in experience in fetal echocardiography has increased the prenatal diagnostic accuracy for congenital cardiac malformations only in selected cases, evaluated by more expert operators. In conclusion the impact of antenatal routine screening for congenital heart disease appears still relatively small.

[Risk assessment of vertical transmission of Toxoplasma infections].

BACKGROUND: It is important to estimate the risk of congenital toxoplasmosis infection and its clinical sequelae. This information will assist the clinical counselling of pregnant women with acute toxoplasmosis and may guide individual decisions on investigative and therapeutic options. METHODS AND PATIENTS: Since January 1998 to July 2000 we collected data on 63 pregnant women referred to our Prenatal Diagnosis Centre for suspicion of acute maternal toxoplasmosis. In case of positive screening tests for IgG and IgM or documented seroconversion, we sent samples of maternal serum to a reference laboratory to detect specific IgM, IgG, IgA antibodies and IgG avidity. We estimated the risk of mother-to-child transmission as high or low in relation to gestational age at the time of maternal seroconversion. Antiparasitic treatment with spiramycin since before confirmation of infection and evaluation of fetal biometry were done. In high risk women we advised amniocentesis for polymerase chain reaction (PCR). If infection was diagnosed in the fetus, the regimen of treatment was changed. Live-born children of all these mothers were followed up serologically for at least 1 year. RESULTS: In 13/63 cases (20%) we excluded maternal infection. Thirty-six out of 63 cases (57%) with high transmission risk underwent an amniocentesis, except one case requesting termination of pregnancy. Four out of the remaining 14 cases estimated at low risk had an amniocentesis for maternal anxiety. Among high risk women, PCR on amniotic fluid was positive in 4 cases (10%): 2 of these requested pregnancy termination, while the other 2 decided to proceed with the pregnancy and the therapy was shifted to 3 weeks courses of pyrimethamine and sulphadiazine with folinic acid alternating with spiramycin. Five infants were lost at follow-up, 20 babies resulted not infected and the remaining 21 are still followed-up. CONCLUSION: It is possible to select by specific serological tests, high risk cases for mother-to-child transmission of infection and to decide a specific approach.

["Defensive medicine" in the choice of cesarean section].

AIM: To evaluate the perception of "Defensive Medicine" by hospital obstetricians and the influence of this attitude on the choice of cesarean delivery. METHODS: Questionnaire sent by mail to a sample of obstetricians of general district, teaching and university hospitals in a region of southern Italy (Puglia). Doctors were selected as the head, the senior and the junior specialist of each department. Independent variables of the study were considered as demographic data of the subjects, seniority, interest in private practice, size of the hospital, background cesarean section rate, personal and site of work exposure to legal claims. Outcome measures were experience and confidence in training for operative vaginal and breech delivery, use of the partogram in labour, opinion about a trial of labour after a previous cesarean section and about section on request, personal perception of Defensive Medicine. Univariate and multivariate analysis of data were performed. RESULTS: The response rate was 83%. According to our data, seniority in service meant confidence in obstetrics manoeuvres and more will to teach them; size of hospitals was positively related to a more rationale approach of the diagnosis of dystocia; heads of units were more prone to accept the patient's wish for a cesarean section. Doctors with large private practices were less likely to be sued and the perception of legal pressure was directly related to the rate of cesarean section in each unit. CONCLUSIONS: Defensive Medicine is a reality that encompasses all categories of doctor in this survey. The only differences were in the rate of perception of legal pressure. We believe that residential programs should be modified in order to improve specialists' understanding of malpractice problems and that the patient-doctor relationship should be ameliorated in public hospitals.

Transvaginal sonography and hysteroscopy in postmenopausal uterine bleeding.

OBJECTIVE: To compare the diagnostic accuracy of transvaginal ultrasound and hysteroscopy in the detection of endometrial pathologies in women with postmenopausal bleeding not using hormonal replacement therapy (HRT). METHODS: Between January 1997 and April 1998, 106 postmenopausal women with uterine bleeding not using HRT underwent a diagnostic work-up including pelvic examination, transvaginal ultrasound, hysteroscopy and endometrial biopsy. Sonographic measurement of endometrial thickness and hysteroscopic findings were compared with histological results. The 'classification tree' method was used to identify cut-off values of sonographic endometrial thickness that could be indicative of a class of uterine pathology. Statistical analysis was performed with the McNemar test. RESULTS: No case of endometrial cancer was found with a cut-off point of 5 mm of endometrial thickness evaluated by ultrasound, whereas all patients with endometrial thickness > or = 15 mm at sonography had an endometrial carcinoma. In the group of patients with endometrial thickness between 6 and 14 mm, we found normal atrophic endometria, benign and malignant pathology. On the other hand, the McNemar test showed a very good correspondence between hysteroscopy and histology (sensitivity 97.5% and specificity 100%), confirming its usefulness in diagnosis of postmenopausal uterine bleeding. CONCLUSIONS: Transvaginal ultrasound has revealed some limitations, mainly in the group of patients with endometrial thickness between 6 and 14 mm. The absence of endometrial malignancy in women with endometrial thickness < or = 5 mm and the high possibility of cancer in those with endometrial thickness > or = 15 mm should be confirmed in larger series. Hysteroscopy proved to be a simple and safe outpatient procedure with a high diagnostic accuracy, and in our opinion it should be considered in all women with postmenopausal uterine bleeding.
