Abstract
OBJECTIVES The purpose of this study was to construct fetal biometric charts between 16 and 40 weeks' gestation that were customized for parental characteristics, race, and parity, using quantile regression analysis. METHODS In a multicenter cross-sectional study, 8070 sonographic examinations from low-risk pregnancies between 16 and 40 weeks' gestation were analyzed. The fetal measurements obtained were biparietal diameter, head circumference, abdominal circumference, and femur diaphysis length. Quantile regression was used to examine the impact of parental height and weight, parity, and race across biometric percentiles for the fetal measurements considered. RESULTS Paternal and maternal height were significant covariates for all of the measurements considered (P < .05). Maternal weight significantly influenced head circumference, abdominal circumference, and femur diaphysis length. Parity was significantly associated with biparietal diameter and head circumference. Central African race was associated with head circumference and femur diaphysis length, whereas North African race was only associated with femur diaphysis length. CONCLUSIONS In this study we constructed customized biometric growth charts using quantile regression in a large cohort of low-risk pregnancies. These charts offer the advantage of defining individualized normal ranges of fetal biometric parameters at each specific percentile corrected for parental height and weight, parity, and race. This study supports the importance of including these variables in routine sonographic screening for fetal growth abnormalities.

Abstract
Interstitial pregnancy is considered one of the most hazardous types of ectopic pregnancies, with a mortality rate of 2-2.5%. We describe a case of a viable monochorionic twin pregnancy in a 35-year-old woman successfully treated with systemic methotrexate associated with bilateral uterine arteries' embolization. β-hCG was undetectable 67 days after the first administration of methotrexate and the ultrasonography performed on day 67 showed the remnant of the gestational sac in the right uterine horn, a thin endometrium and a normal myometrial vascularization. Conservative treatment allowed us to avoid surgical treatment and to preserve the patient's fertility.

Abstract
Catamenial epilepsy is defined as a pattern of seizures that changes in severity during particular phases of the menstrual cycle, wherein estrogens are proconvulsant, increasing the neuronal excitability; and progesterone is anticonvulsant, enhancing GABA-mediated inhibition. Thus, changes in serum estradiol/progesterone ratio throughout a normal reproductive cycle bring about an increased or decreased risk of seizure occurrence. To date, there are no specific drug treatments for catamenial epilepsy however, non-hormonal and hormonal therapies have been proposed. The aim of this review is to report preclinical and clinical evidences about the relationship between female reproductive steroids and epileptic seizures, and to describe treatment approaches for catamenial epilepsy.

Abstract
OBJECTIVE Antepartum amnioinfusion is a relatively recent procedure introduced with fetal medicine techniques. It is usually indicated for severe oligohydramnios in order to avoid the related complications such as pulmonary hypoplasia, the deforming effects of oligohydramnios, variable fetal heart rate decelerations and intraventricular hemorrhage. Antepartum amnioinfusion is also employed to improve ultrasound visualization in cases with oligohydramnios. Our objective was to evaluate the benefits and complications related to this procedure which is still less commonly used compared to intrapartum amnioinfusion, and whose risks are therefore not well established. STUDY DESIGN Reports of study designs identified from searches of MEDLINE, PUBMED, the Cochrane Collaboration, specialized databases and bibliographies of review articles were identified. Studies in women who underwent amnioinfusion between 1987 and 2002 were included. RESULTS AND CONCLUSIONS Amnioinfusion seems to offer several benefits, in terms of both prenatal diagnosis and favorable perinatal outcome. Most clinical experiences report that amnioinfusion is safe, both for the mother and for the fetus. However, randomized control-group studies subdivided on the basis of the cause of oligohydramnios (e.g. premature rupture of membranes, fetal growth restriction, obstructive uropathy and renal agenesis) could help to determine the advantages and risks linked to this procedure. Prospective randomized studies should therefore be encouraged, to clarify any possible doubts regarding the procedure, before it can be introduced into routine practice in the management of oligohydramnios.

Abstract
The acrofacial dysostosis (AFD) syndromes are an heterogeneous group of disorders with undefined classification and inheritance. We report the sonographic and clinical features of an AFD fetus with predominantly pre-axial forms. We made a prenatal diagnosis of Nager syndrome but postnatal examination showed post-axial defects previously undetectable by ultrasound.

Abstract
Rupture of a splenic artery aneurysm (SAA) during pregnancy is a rare and severe condition. A 35-year-old woman at 34 weeks' gestation came to our observation for acute abdominal pain. After being diagnosed with intra-pancreatic SAA rupture, she was delivered of a live fetus by cesarean section. This is a rare case with both fetal and maternal survival.

Abstract
AIM The purpose of our study was to evaluate the ability of the International Ovarian Tumor Analysis (IOTA) classification and its impact on the identification of benign and malignant adnexal masses by less experienced sonographers. METHODS One hundred and five patients undergoing elective surgical treatment for single adnexal masses at the University of Parma were enrolled. After the final diagnosis, we had the ultrasound recordings reviewed retrospectively by a group of three residents, and the features of each adnexal mass were evaluated according to the morphological score reported by the IOTA Group. RESULTS Based solely on the qualitative classification of the IOTA Group unilocular cysts were associated with a high, significant probability of a benign lesion (odds ratio (OR) = 12.6 (95% CI, 1.61-99.10), P < 0.001). This probability remained high also with multilocular cysts (OR = 7.9 (95% CI, 1.00-62.38), P < 0.05). By contrast, multilocular-solid cysts were significantly associated with the probability of malignancy (OR = 6.4 (95% CI, 1.81-22.70), P < 0.001), as were solid masses (OR = 5.5 (95% CI, 1.48-20.92), P < 0.05). None of the five ultrasound categories of lesions could be significantly correlated with borderline masses. CONCLUSIONS A simple qualitative classification based solely on the recognition of five different ultrasound categories may be enough to guide the physician to an accurate identification of the nature of the mass. Our findings confirm the diagnostic reliability of the IOTA Group classification by less experienced sonographers. This system is especially helpful because it is capable of discriminating between ovarian masses without further tests and clinical examinations.

Abstract
BACKGROUND AND AIM OF THE WORK Diagnosis and treatment of endometrial pathology nowadays ranges from clinical examination to transvaginal ultrasound (TVS), saline infusion sonohysterography (SIS), hysterosalpingography (HSG) and hysteroscopy (HYS). However, many gynaecologists prescribe blind endometrial biopsies, such as Vacuum ABRAsion (VABRA), as single strategy. The purpose of this work is to evaluate whether the procedure of VABRA should still be performed alone in perimenopausal women with abnormal uterine bleeding, compared to biopsies and samples obtained after a previous transvaginal sonohysterography. METHODS We retrospectively reviewed the records of 216 patients referred to our Ultrasonography and Day-Surgery Center between November 2005 and December 2006 with persistent premenopausal uterine bleeding, spotting or postmenopausal bleeding. One hundred and five out of 216 pts.(48.6%), defined as Group "A", underwent a sole endometrial sampling by VABRA; 111 out of 216 pts. (51.4%), Group "B", had a SIS first. RESULTS Vabra showed a poor sensitivity in the diagnosis of polyps (19%) and submucosal myoma, with a negative predictive value of 73.4%. Likelihood ratio for test negative was 0.81, with an overall diagnostic accuracy of 75%. CONCLUSIONS This study confirms that blind endometrial biopsies should no longer be performed as the only diagnostic strategy in perimenopausal women with abnormal uterine bleeding. On the other hand, a sonohysteroscopy-guided approach allows an accurate detection of focal lesions; nevertheless, it should not be forgotten that SIS is an ultrasound based procedure, and may provide further information on endometrial thickness, myomas, ovaries and pelvis.

Abstract
Ultrasound screening of structural fetal malformations is mainly based on the use of ultrasounds during the second trimester of pregnancy. The diagnostic sensibility of ultrasounds varies in the different multicentric studies reported in literature and is correlated to different factors: gestation period, type of malformation, number of ultrasounds performed, operator experience, etc. Third trimester ultrasounds may identify late-onset malformations and offer adequate information for postnatal assistance.

Abstract
OBJECTIVE The twin-twin transfusion syndrome (TTTS) is a complication of monozygotic-monochorionic twinning and is a direct result of transplacental communication between the circulations of twins. When acute TTTS occurs in the second trimester, the perinatal mortality can be as high as 95% in the absence of treatment. For this reason, several aggressive, even desperate treatment modalities have been attempted including selective fetocide, umbilical cord ligation, maternal digoxin therapy. None have gained wide acceptance. Serial drainage amniocentesis or amnioreduction is actually the most widely used therapy. More recently, laser ablation under fetoscopic guidance of placental vessel has been reported in an attempt to improve survival. The objective of this review was to evaluate the impact of treatment modalities in TTTS. STUDY DESIGN Reports of prospective and retrospective trials and other study designs in English identified from searches of MEDLINE, EMBASE, specialized databases, bibliographies of review articles. Study on twin pregnancies affected by TTTS between 1990 and 2003 that met our inclusion criteria were included. RESULTS AND CONCLUSIONS No single therapy is associated with a uniformly improved outcome for the involved twins and success is primarily related to gestational age and severity at diagnosis. Standard therapy has commonly been serial amnioreduction, which appears to improve the overall outcome. Intertwin sepstostomy similary improves outcome but has no survival advantage over serial amnioreduction. Selective fetoscopic laser photocoagualtion has emerged as an alternative treatment strategy in TTTS with at least comparable if not superior survival to serial amnioreduction. TTTS diagnosed before 26 weeks' gestation has significantly better survival rates and fewer neurological sequelae after laser therapy than amnioreduction.

Abstract
Ultrasound evaluation of amniotic fluid volume (AFV) is frequently used to detect fetuses at high risk for an adverse outcome - an event that is often correlated with AFV abnormalities. As is well known, ultrasound is a non invasive procedure, which makes it ideal for application on a very large scale: in practice, it can be used for routine monitoring of all pregnancies and, not infrequently, for repeat AFV determination in those cases where there is the suspect of amniotic fluid abnormalities. Sonographic quantification of AFV, whether it is performed through a simple visual estimation or through biometric measurement of one or more amniotic fluid pockets, can never represent a true "quantitative" method and its actual reliability has not consistently been proved by scientific evidence. Moreover, even though ultrasound AFV evaluation is indispensable in the management of high-risk pregnancies, there is no consensus on which ultrasound index is the most accurate in predicting perinatal morbidity and mortality. The sonographer can evaluate AFV by directly observing amniotic fluid pockets and his experience is crucial for a high reliability of the procedure. When pathological AFV changes are present, especially if the examination is performed by a not so expert sonographer, biometric measurements (Single Deepest Pocket, Amniotic Fluid Index, Two-Diameter Pocket) with their respective reference ranges might be helpful in confirming the diagnosis of oligohydramnios or hydramnios. A complete review of all tests performances and confidences is made by the Authors.

Abstract
We studied a cohort of 41 singleton pregnancies induced at term with prostaglandins and, when necessary, oxytocin. We evaluated with ultrasound the amniotic fluid index (AFI) and the largest vertical pocket (LVP), at least 2 days before the delivery, to compare the sonographic measurement of amniotic fluid with fetal distress and perinatal outcome. We analysed the incidence of fetal distress using intrapartum monitoring of fetal heart rate, considering the absence of variability, the presence of persistent severe variable and/or late decelerations. The oligohydramnios group, indipendently by ultrasound index, showed the same incidence of abnormal FHR, and rate of Cesarean section for fetal distress as the group with normal amniotic fluid. In conclusion there is no significant difference between the group of patients with oligohydramnios and the one with normal amniotic fluid regarding the perinatal outcome in induced labor.

Abstract
In this retrospective analysis we studied 1489 women who underwent prenatal invasive diagnostic procedures between January 2000 and December 2002. We examine the influence of risk factors and the incidence of early complications following amniocentesis and chorion villus sampling, in particular the incidence of fetal loss. The study group included 438 women who underwent CVS and 1051 underwent amniocentesis. For each woman we studied anamnestic risk factors (recurrent pregnancy losses, fibroids, twin birth, uterine hematic loss), intraoperative risk factors (repetition of the insertion, transplacental sample, hematic liquid, early bleeding) and postoperative risk factors (pelvic pain, hematic losses, liquid losses, spastic pain, fever). In our data the miscarriage incidence was 1% for CVS and 1.7% for amniocentesis. Our results showed that in relation to CVS, the presence of fibroids gives an OR of miscarriage of 68 (95% C.I.=6.50-659.78; p=0.000). In relation to amniocentesis, the incidence of hematic losses gives an OR of miscarriage of 10 (95% C.I.=1.50-32.94; p=0.04). If these results were confirmed by other experiences, they could induce obstetricians to avoid CVS in these women with uterine fibroids and hence recommend amniocentesis to them. Particular attention has to be taken in those patients with vaginal bleeding following amniocentesis.

Abstract
In this study it has been evaluated the connection between the maternal immune status and the obstetrical factors on the one hand end the perinatal transmission of HIV in the other as well as, the effects of zidovudine prophylaxis and elective caesarean section on vertical HIV transmission. From January 1987 to September 1999, 60 HIV infected pregnant women were followed with their 64 infants. From July 1995 15 women and their respective children were treated with zidovudine prophylaxis (protocol ACTG 076); from June 1997, in 8 of these patients a systematic caesarean section was performed (7 electively and 1 on an emergent basis). The transmission rare was 20.5% among the 44 children in the group without zidovudine prophylaxis, compared with 7.1% among the 14 children in the group receiving Zidovudine. As for as the mother-child pairs receiving Zidovudine therapy, the rate of vertical transmission was 0% for the 7 mothers who underwent elective cesarean section and 14.3% for the 7 mothers with other ways of delivery. The interaction between zidovudine prophylaxis and elective caesarean section was associated with the lowest rate of vertical HIV transmission.

Abstract
Vertical transmission of HIV is by far the most important way of infection in pediatric patients. Transmission rate of infection varies between 15-40% in the absence of antiretroviral prophylaxis. Only 2% of infected pregnant women who underwent caesarean section and zidovudine treatment transmitted the infection to their newborns. From January 1995 to September 2000 twenty seropositive pregnant women and their twenty newborns were followed at the Azienda Ospedaliera of Parma. Nine women (45%) were treated with only zidovudine according to the ACTG 076 protocol; eight women (40%) continued the treatment they were assuming before pregnancy with the eventual addition of zidovudine. 3 women (15%) were not treated because HIV infection was only detected after delivery. 15 women underwent caesarean section, in 13 cases in association to antiretroviral prophylaxis: in the remaining 2 cases no intrapartum treatment was started due to the urgency of delivery. The rate of vertical transmission among the 20 women was 5% (1/20), significantly less then that observed (20.5%) among 31 pregnant HIV women followed in Parma from January 1987 to December 1994 and not treated with antiretroviral prophylaxis and/or cesarean section (Magnani G. Personal data). The only infected baby was born by vaginal delivery. No transmission was observed in the group of pregnant women who underwent the combination of antiretroviral prophylaxis and cesarean section.

Abstract
Amnioinfusion is a relatively recent procedure introduced among fetal medicine techniques. Its applications focus on two different methods: transcervical and transabdominal. The first procedure usually is carried out during "intrapartum amnioinfusion" to prevent or treat fetal heart rate (FHR) decelerations related to oligohydramnios or to dilute thick meconium staining of the amniotic fluid. The latter method used during "antepartum amnioinfusion" is usually indicated for severe oligohydramnios in order to avoid the complications related such as pulmonary hypoplasia, deforming effects of oligohydramnios, variable FHR decelerations and intraventricular hemorrhages. Antepartum amnioinfusion, also used to improve ultrasound visualisation in presence of oligohydramnios, is less employed as compared to intrapartum amnioinfusion, therefore its risks are not well established. In order to study possible adverse effects on the mother or foetus, fifty five patients affected by oligohydramnios at 17th-34th week of gestational age were submitted to antepartum amnioinfusion (1-5 procedures) and were matched retrospectively with forty seven women with the same characteristics treated with the conservative and expectant management. The trend of pregnancy was the same for both groups in relation to maternal fever > 38 degrees (10.9% in the amnioinfused group vs 17.0% in control group ns), leukocyte count > 18,000/mm3 (25.5% vs 21.3%, ns), C-reactive protein > 10 ng/ml (10.9% vs 6.4%, ns). The latency period between admission and delivery was significantly longer in the amnioinfused group than in the control one [21 (range 1-98) vs 9 days (range 0-72); p < 0.001] and the frequency of Apgar score < 7 at the 5th min was less represented in the amnioinfused group than in the control group (32.3% vs 66.6%; p < 0.001). In conclusion, it was interesting to note that antepartum amnioinfusion seems to increase the latency period between premature rupture of membranes and delivery, but it remains to clarify if this procedure is as much safe for the fetus as for the mother.

Abstract
The incidence of hepatitis C in childhood is approximately 0.4%. The mode of transmission can be parenteral, sexual, occupational and also vertical. The latter has an incidence that varies widely and it increases in the case of human immuno-deficiency virus (HIV) coinfection and high titers of HCV in the mother. The vertical transmission is not influenced by breast feeding, however, data are discrepant with regard to child delivery (cesarean section vs vaginal delivery). Ninety-seven babies born from mothers with hepatitis C from 1996 to 1999, were evaluated prospectively in the Day Hospital of the Pediatric Department of Parma. The protocol of observation established a blood sampling for titers of antibodies anti-HCV and HCV-RNA at the 3rd trimester of pregnancy and subsequent clinical and biochemical controls at 3-6-9-12-15 and 18 months. Thirty (31.2%) out of the 96 mothers evaluated were positive for antibodies anti-HCV and 66 (68.8%) were positive for antibodies anti-HCV and HCV-RNA. Five (5.15%) out of the 97 babies evaluated were infected by HCV. Of these 4 were delivered vaginally and 1 by cesarean section. Of the 3 babies born to mothers with HIV coinfection, none was infected by HIV, but 1 was infected by HCV. Vertical transmission is increased by HCV viral load or HIV coinfection in the mother. The vaginal delivery and breastfeeding do not represent an additional risk factor.

Abstract
Puerpera and baby's early discharging falls within a bigger project that deals with the reduction of medical treatment and with the razionalization of economic resources. We can talk about early discharging when it occurs by 48 hours after a vaginal childbirth and by 96 hours after a cesarean section. When the mother and the baby have been discharged from hospital, their health will chiefly depend on the efficiency of the sanitary organization that works on the territory. If the nursing service at home is competent and specialized, the stay in hospital will get shorter and shorter. The most deepen studies about early discharging after vaginal childbirth agree upon the lack of any risk both for the mother and for the baby. Early discharging is possible without any risk for the mother's health after a cesarean section as well, but only if the woman is well-disposed, if she is at low risk, if she answers to predetermined criteria of eligibility, and if she has an adequate follow-up when she comes back home. On the basis of these evidences, we have traced a clinical outline that draws the early discharging in obstetrics that, in the last five years, has led to a progressive reduction of the stay in hospital both after vaginal childbirth and after cesarean section.

Abstract
OBJECTIVE The aim of our study was to evaluate the efficacy of Doppler velocimetry and cardiotocography in surveillance of the fetus affected by severe fetal growth retardation (FGR) and hence their capacity in predicting adverse perinatal outcome. This could therefore permit the timing of delivery thus reducing perinatal morbidity and mortality. METHODS 53 women with high risk pregnancies, all suffering from various pathologies such as gestational hypertension, preeclampsia, HELLP syndrome, Antithrombin III deficit, and in whom FGR (fetal abdominal circumference < 2.5th percentile for gestational age) diagnosed between the 24th and 35th week of gestational age, were retrospectively enrolled in the study. Doppler velocimetry was carried out on the main vascular districts - both arterial [umbilical artery (UA), middle cerebral artery (MCA), aorta (Ao) and uterine artery] and venous [umbilical vein (UV), ductus venosus (DV), inferior vena cava (IVC)]. Also evaluated was the amniotic fluid index (AFI). Daily non stress tests (NST) were conducted at least thrice a day for an overall period of not shorter than 60 min. Also considered were the methods of delivery and the perinatal outcome, e.g. gestational age at birth, perinatal mortality, incidence resuscitation, etc. RESULTS The 53 patients studied were subdivided into three groups on the basis of the initial velocimetric exam of the umbilical and uterine arteries. Group A was comprised of those with altered waveforms of the UA, Group B those with altered waveforms on the uterine artery while Group C contained those with altered waveforms both of the UA and uterine artery. The period of study for group C was on average six days (p < 0.05) while for groups A and B they were on average 10 and 22 days, respectively. Group C also presented higher incidences of altered waveforms in the venous compartment, i.e. absent or reversed end diastole (ARDEF) was observed in 89% of the cases versus 0% and 7.6% observed in Group A and B, respectively. Altered waveforms in the DV and pulsations in the UV were both observed in Group C while the same was not observed in either group A or B. The NST did not show any substantial difference between the groups - only as the appearance of decelerations present in over half the cases in all groups at the end of the study. Group C also presented higher incidences in adverse perinatal outcome as compared to groups A and B such as as low birth weight (868 g vs 1,324 g & 1,397 g, p < 0.001), neonatal resuscitation (52.6% vs 0% & 7.6% p = 0.001), longer periods of admission to neonatal intensive care unit (67 days vs 32 & 33 p < 0.001) and perinatal mortality (36% vs 0 & 0, p < 0.05). The velocimetric indices which appear to better predict perinatal mortality are those related to the venous compartment giving a diagnostic accuracy of 92.8% (KI > 0.75) in case of pulsations in the UV, 86.6% (KI > 0.75) with alterations on the DV, and of 78.5% (KI > 0.40) for those on the IVC. Cardiotocography revealed to be less capable in predicting perinatal mortality giving a diagnostic accuracy of 66.6% (KI > 0.40) with a non reactive, non variable NST. CONCLUSION The data presented show that velocimetric modifications in the fetal venous compartment constitute a relevant prognostic sign in the prediction of perinatal mortality and neonatal resuscitation. The further the vessels compromised are from the heart, the higher is the relative risk for perinatal mortality, equal to 5.0 (95% C.I. = 0.61-40.9) with alterations on the IVC, of 8.2 (95% CI = 1.04-61.5) when they involve the DV, and of 18.0 (95% = 2.44-133) when pulsations are obtained on the UV.

Abstract
BACKGROUND The study analyses the diagnostic possibilities regarding ovarian neoplasms offered by different clinical approaches: B-mode morphological ultrasonographic examination, colour Doppler and Doppler pulsed ultrasonography, and lastly the assay of a number of tumour markers. METHODS A prospective study was carried out in 125 selected patients attending the Ultrasonography unit of the Obstetrics and Gynecology Clinic at Parma University between June 1997 and June 1999 who presented an adnexal mass . All patients underwent transvaginal ultrasonography (multifrequency vaginal probe 5.0-6.5 MHz, Esaote Idea, Genova) to characterise the mass, applying 5 different ultrasonographic scores: Granberg, Sassone, Di Priest, Lerner, Ferrazzi. Colour Doppler imaging was then performed to analyse the vascularisation of the mass, also using pulsed Doppler to study a number of velocimetric parameters: pulsatility index, index of resistance, systolic and diastolic peak velocity, mean velocity. All the patients underwent surgery using laparotomy or video laparoscopy, accompanied by histological analysis. A number of different tumour markers were assayed prior to surgery: Cal25, CA19-9, CEA, beta-HCG, alpha-fetoprotein. RESULTS Out of 127 pelvic masses examined, histological analysis showed that 19 were malignant and 108 benign. The diagnostic accuracy of malignancy was comparable for the 5 scores studied, with a minimum of 57.48% for Lerner and a maximum of 77.16% for Di Priest. The central importance of vascularisation was the only significant parameter among those analysed using colour Doppler which was useful for the diagnosis of a malignant neoplasm, with a diagnostic accuracy of 82.95%. No indicator obtained using pulsed Doppler was useful for diagnostic purposes. CA125 was the only tumour marker that revealed a statistically significant difference emerged between the benign (21.6 U/ml) and malignant (220.8 U/ml) masses. Its diagnostic accuracy was 75.58%. CONCLUSIONS This study confirmed that the three methods analysed do not differentiate substantially in their overall diagnostic capacity of malignant ovarian neoplasms. The best performances for ecographic scores (Di Priest) did not exceed a sensitivity of 89.47% with a 21.25% incidence of false positives; this was comparable to CA125 with a sensitivity of 85.71% and false positives in 22.09%. In relation to the central importance of vascularisation, colour Doppler achieved a lower sensitivity (55.55%), but this was confirmed by a low incidence of false positives (7.95%). This revealed its importance as a useful method, especially for excluding the presence of malignant tumours.

Abstract
The prevalence of antibodies for one or more HCV antigens was 2.3% of 1,347 mothers at childbirth. Compared with the principal factors studied, the presence of antibodies was more frequent in women who were carriers of HIV infection (3/3), in those who had suffered liver diseases (5/37) or who had had transfusion (3/25). This was as opposed to women who did not have any risk factor (p < 0.001). The prevalence of HCV-RNA was 1.3%; in relation to the antibody state, such a condition was more frequent in subjects with antibodies for 3 or 4 antigens (about 80%) compared with those who were positive for 1 or 2 antigens. HCV-RNA of the same genotype as the mother (type 1; 1a) was also found in the funicular blood of 2 of the 18 babies born to mothers who were positive for HCV-RNA. In the course of the follow-up (from the 3rd to the 18th month) the viral RNA was not found in any of the babies, nor was it found in the 2 who were positive at birth. Even the antibodies gradually disappeared, although slowly. At the 10th month, 91% of the babies resulted as having no antibodies and at the 18th month none of the babies resulted as having antibodies. Breast-feeding also appeared to have no influence on the transmission of the infection; out of 18 viremic mothers indeed 12 (67%) breast-fed their babies.

Abstract
Plasma concentration, urinary excretion and renal clearance of free, total and esterified L-carnitine were monitored monthly in 14 women during the last 6 months of pregnancy and 1 month after delivery. Plasma concentration and renal clearance measured 1 month after delivery overlapped with normal values for females of comparable age, and were considered the reference values for further comparisons. Plasma concentration of free, total and esterified L-carnitine decreased during pregnancy, reaching values as low as half of those measured 1 month after delivery, whereas urinary excretion and renal clearance, mainly of L-carnitine esters, increased, with renal clearance reaching a peak at the 16th week of pregnancy. Pregnancy thus leads to a reversible secondary deficiency of L-carnitine. The involvement of L-carnitine in the excretion of an excess of acyl-S-coenzyme A groups to prevent a possible systemic acidosis, as well as hormonal changes and a reduction of L-carnitine biosynthesis, could play a significant role in the variations in L-carnitine metabolism encountered in pregnancy. As physiological components of L-carnitine are excreted via a saturable tubular reabsorption, their threshold seems to follow plasma concentration, even when they decrease markedly, as in pregnancy.

Abstract
In the present study the authors, on the basis of the existing literature, analyse the delivery problem in previous cesarean section patient, especially about maternal mortality and morbidity. After cesarean section vaginal delivery may occur only in selected patients, with precautionary measures and continuous monitoring in labor. The maternal mortality is lower in vaginal delivery patients after cesarean section than in iterative cesarean section patients; also the post operating complications are more frequent after iterative cesarean section. Perinatal mortality is in relation to uterine rupture, perinatal morbidity to iatrogenic prematurity and neonatal respiratory adaptation.
