RÉSUMÉ

OBJECTIVE: Polycystic ovary syndrome is associated with reproductive and metabolic dysfunction; in fact, treatment aims in PCOS focus on optimizing healthy weight, improving underlying hormonal disturbances, preventing future reproductive and metabolic complications, and improving quality of life. PATIENTS AND METHODS: This pilot study considered 8 overweight females (BMI > 30) in reproductive age with PCOS. Patients were treated with a galenical preparation mixture containing resveratrol and alpha-lipoic acid in association with vitamin D, B and folic acid for 12 weeks, after which anthropometric assessment was conducted. RESULTS: After 12 weeks of treatment, BMI, anthropometry and bioimpedance parameters were all reduced in the treated patients compared to baseline. CONCLUSIONS: The present nutraceutical combination resulted beneficial for improving the metabolic profile of women with PCOS, paving the way for new nutraceutical strategies for the management of metabolic disturbances in PCOS.

RÉSUMÉ

OBJECTIVES: To describe a newly developed machine-learning (ML) algorithm for the automatic recognition of fetal head position using transperineal ultrasound (TPU) during the second stage of labor and to describe its performance in differentiating between occiput anterior (OA) and non-OA positions. METHODS: This was a prospective cohort study including singleton term (> 37 weeks of gestation) pregnancies in the second stage of labor, with a non-anomalous fetus in cephalic presentation. Transabdominal ultrasound was performed to determine whether the fetal head position was OA or non-OA. For each case, one sonographic image of the fetal head was then acquired in an axial plane using TPU and saved for later offline analysis. Using the transabdominal sonographic diagnosis as the gold standard, a ML algorithm based on a pattern-recognition feed-forward neural network was trained on the TPU images to discriminate between OA and non-OA positions. In the training phase, the model tuned its parameters to approximate the training data (i.e. the training dataset) such that it would identify correctly the fetal head position, by exploiting geometric, morphological and intensity-based features of the images. In the testing phase, the algorithm was blinded to the occiput position as determined by transabdominal ultrasound. Using the test dataset, the ability of the ML algorithm to differentiate OA from non-OA fetal positions was assessed in terms of diagnostic accuracy. The F1 -score and precision-recall area under the curve (PR-AUC) were calculated to assess the algorithm's performance. Cohen's kappa (κ) was calculated to evaluate the agreement between the algorithm and the gold standard. RESULTS: Over a period of 24 months (February 2018 to January 2020), at 15 maternity hospitals affiliated to the International Study group on Labor ANd Delivery Sonography (ISLANDS), we enrolled into the study 1219 women in the second stage of labor. On the basis of transabdominal ultrasound, they were classified as OA (n = 801 (65.7%)) or non-OA (n = 418 (34.3%)). From the entire cohort (OA and non-OA), approximately 70% (n = 824) of the patients were assigned randomly to the training dataset and the rest (n = 395) were used as the test dataset. The ML-based algorithm correctly classified the fetal occiput position in 90.4% (357/395) of the test dataset, including 224/246 with OA (91.1%) and 133/149 with non-OA (89.3%) fetal head position. Evaluation of the algorithm's performance gave an F1 -score of 88.7% and a PR-AUC of 85.4%. The algorithm showed a balanced performance in the recognition of both OA and non-OA positions. The robustness of the algorithm was confirmed by high agreement with the gold standard (κ = 0.81; P < 0.0001). CONCLUSIONS: This newly developed ML-based algorithm for the automatic assessment of fetal head position using TPU can differentiate accurately, in most cases, between OA and non-OA positions in the second stage of labor. This algorithm has the potential to support not only obstetricians but also midwives and accoucheurs in the clinical use of TPU to determine fetal occiput position in the labor ward. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

RÉSUMÉ

Young pregnant women with HIV may be at significant risk of unplanned pregnancy, lower treatment coverage, and other adverse pregnancy outcomes. In a large cohort of pregnant women with HIV in Italy, among 2979 pregnancies followed in 2001-2016, 9·0% were in women <25 years, with a significant increase over time (2001-2005: 7·0%; 2006-2010: 9·1%; 2011-2016: 12·2%, P < 0·001). Younger women had a lower rate of planned pregnancy (23·2% vs. 37·7%, odds ratio (OR) 0·50, 95% confidence interval (CI) 0·36-0·69), were more frequently diagnosed with HIV in pregnancy (46·5% vs. 20·9%, OR 3·29, 95% CI 2·54-4·25), and, if already diagnosed with HIV before pregnancy, were less frequently on antiretroviral treatment at conception (<25 years: 56·3%; ⩾25 years: 69·0%, OR 0·58, 95% CI 0·41-0·81). During pregnancy, treatment coverage was almost universal in both age groups (98·5% vs. 99·3%), with no differences in rate of HIV viral suppression at third trimester and adverse pregnancy outcomes. The data show that young women represent a growing proportion of pregnant women with HIV, and are significantly more likely to have unplanned pregnancy, undiagnosed HIV infection, and lower treatment coverage at conception. During pregnancy, antiretroviral treatment, HIV suppression, and pregnancy outcomes are similar compared with older women. Earlier intervention strategies may provide additional benefits in the quality of care for women with HIV.

RÉSUMÉ

OBJECTIVES: The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. METHODS: Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. RESULTS: The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/µL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). CONCLUSIONS: Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple children may proceed safely and confidently with subsequent pregnancies.

RÉSUMÉ

This paper highlights the utility of 2D and 3D ultrasonography in the prenatal diagnosis of facial dysmorphisms suggestive of very rare syndromes such as 3-M syndrome. Two pregnant women at risk for fetal skeletal dysplasias were referred to our clinic for 2D/3D ultrasound scan in the second trimester of pregnancy. Only one of the patients had a familial history of 3-M syndrome. Karyotyping and genetic testing of abortion material were performed in both cases. 2D ultrasonography revealed growth retardation of the long bones in both cases. In the case without a familial history of the syndrome, 2D and 3D ultrasonography showed an absence of nasal bones and a flat malar region suggestive of 3-M syndrome, although the difficult differential diagnosis included other dysmorphic growth disorders with prenatal onset. The karyotype was normal but the pregnancy was terminated in both cases. Postmortem examination confirmed 3-M syndrome as indicated by prenatal findings. In high-risk cases with a familial history of 3-M syndrome, prenatal diagnosis of 3-M syndrome is possible by analyzing fetal DNA. In the absence of risk, a definitive prenatal diagnosis is often not possible but may be suspected in the presence of shortened long bones, normal head size and typical flattened malar region (midface hypoplasia) shown on complementary 2D and 3D sonograms. 2D and 3D ultrasonography has been shown to offer reliable information for the prenatal study of skeletal and facial anomalies and can be useful if there is a suspicion of 3-M syndrome in a pregnancy not known to be at risk.

RÉSUMÉ

PURPOSE: To provide information about main pregnancy outcomes in HIV-HCV coinfected women and about the possible interactions between HIV and HCV in this particular population. METHODS: Data from a multicenter observational study of pregnant women with HIV, conducted in Italian University and Hospital Clinics between 2001 and 2015, were used. Eligibility criteria for analysis were HCV coinfection and at least one detectable plasma HCV-RNA viral load measured during pregnancy. Qualitative variables were compared using the Chi-square or the Fisher test and quantitative variables using the Mann-Whitney U test. The Spearman's coefficient was used to evaluate correlations between quantitative variables. RESULTS: Among 105 women with positive HCV-RNA, median HCV viral load was substantially identical at the three trimesters (5.68, 5.45, and 5.86 log IU/ml, respectively), and 85.7 % of the women had at least one HCV-RNA value >5 log IU/ml. Rate of preterm delivery was 28.6 % with HCV-RNA <5 log IU/ml and 43.2 % with HCV-RNA >5log (p = 0.309). Compared to women with term delivery, women with preterm delivery had higher median HCV-RNA levels (third trimester: 6.00 vs. 5.62 log IU/ml, p = 0.037). Third trimester HIV-RNA levels were below 50 copies/ml in 47.7 % of the cases. No cases of vertical HIV transmission occurred. Rate of HCV transmission was 9.0 % and occurred only with HCV-RNA levels >5 log IU/ml. CONCLUSIONS: Coinfection with HIV and HCV has relevant consequences in pregnancy: HIV coinfection is associated with high HCV-RNA levels that might favour HCV transmission, and HCV infection might further increase the risk of preterm delivery in women with HIV. HCV/HIV coinfected women should be considered a population at high risk of adverse outcomes.

RÉSUMÉ

OBJECTIVE: To evaluate the prevalence and consequences of late antenatal booking (13 or more weeks gestation) in a national observational study of pregnant women with HIV. METHODS: The clinical and demographic characteristics associated with late booking were evaluated in univariate analyses using the Mann-Whitney U test for quantitative data and the chi-square test for categorical data. The associations that were found were re-evaluated in multivariable logistic regression models. Main outcomes were preterm delivery, low birthweight, nonelective cesarean section, birth defects, undetectable (<50 copies/mL) HIV plasma viral load at third trimester, delivery complications, and gender-adjusted and gestational age-adjusted Z scores for birthweight. RESULTS: Rate of late booking among 1,643 pregnancies was 32.9%. This condition was associated with younger age, African provenance, diagnosis of HIV during pregnancy, and less antiretroviral exposure. Undetectable HIV RNA at third trimester and preterm delivery were significantly more prevalent with earlier booking (67.1% vs 46.3%, P < .001, and 23.2% vs 17.6, P = .010, respectively), whereas complications of delivery were more common with late booking (8.2% vs 5.0%, P = .013). Multivariable analyses confirmed an independent role of late booking in predicting detectable HIV RNA at third trimester (adjusted odds ratio [AOR], 1.7; 95% CI, 1.3-2.3; P < .001) and delivery complications (AOR, 1.8; 95% CI, 1.2-2.8; P = .005). CONCLUSIONS: Late antenatal booking was associated with detectable HIV RNA in late pregnancy and with complications of delivery. Measures should be taken to ensure an earlier entry into antenatal care, particularly for African women, and to facilitate access to counselling and antenatal services. These measures can significantly improve pregnancy management and reduce morbidity and complications in pregnant women with HIV.

RÉSUMÉ

OBJECTIVE: We used data from a national study of pregnant women with HIV to evaluate the prevalence of congenital abnormalities in newborns from women with HIV infection. DESIGN: Observational study. SETTING: University and hospital clinics. POPULATION: Pregnant women with HIV exposed to antiretroviral treatment at any time during pregnancy. METHODS: The total prevalence of birth defects was assessed on live births, stillbirths, and elective terminations for fetal anomaly. The associations between potentially predictive variables and the occurrence of birth defects were expressed as odds ratios (ORs) with 95% confidence intervals (95% CIs) for exposed versus unexposed cases, calculated in univariate and multivariate logistic regression analyses. MAIN OUTCOME MEASURES: Birth defects, defined according to the Antiretroviral Pregnancy Registry criteria. RESULTS: A total of 1257 pregnancies with exposure at any time to antiretroviral therapy were evaluated. Forty-two cases with major defects were observed. The total prevalence was 3.2% (95% CI 1.9-4.5) for exposure to any antiretroviral drug during the first trimester (23 cases with defects) and 3.4% (95% CI 1.9-4.9) for no antiretroviral exposure during the first trimester (19 cases). No associations were found between major birth defects and first-trimester exposure to any antiretroviral treatment (OR 0.94, 95% CI 0.51-1.75), main drug classes (nucleoside reverse transcriptase inhibitors, OR 0.95, 95% CI 0.51-1.76; non-nucleoside reverse transcriptase inhibitors, OR 1.20, 95% CI 0.56-2.55; protease inhibitors, OR 0.92, 95% CI 0.43-1.95), and individual drugs, including efavirenz (prevalence for efavirenz, 2.5%). CONCLUSIONS: This study adds further support to the assumption that first-trimester exposure to antiretroviral treatment does not increase the risk of congenital abnormalities.

RÉSUMÉ

PURPOSE: This study assessed the diagnostic accuracy of pelvic magnetic resonance (MR) imaging completed by MR colonography for the preoperative evaluation of deep pelvic endometriosis in patients undergoing laparoscopic surgery. MATERIALS AND METHODS: A total of 143 patients (mean age 34.3 ± 5.1 years) with a clinical suspicion of deep pelvic endometriosis were assessed by pelvic MR and MR colonography. All patients underwent laparoscopic surgery 3-10 weeks after the MR examination. The presence, location, number and extent of endometriotic lesions were evaluated. Data obtained with MR were compared with surgical findings. MR sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and diagnostic accuracy values were calculated for each site by considering the laparoscopic and histological findings as the reference standard. RESULTS: Laparoscopy confirmed the presence of endometriosis in 119/143 patients (83%); in 76/119 (64%) deep pelvic endometriosis was diagnosed, whereas in the remaining 43/119 (36%), superficial peritoneal implants and endometriomas were found. In 32/119 (27%) patients, intestinal lesions were detected. MR had sensitivity, specificity, PPV, NPV and diagnostic accuracy values of 67-100%, 85-100%, 83-100%, 84-100% and 84-100%, respectively, in recognising lesions located in different pelvic sites. CONCLUSIONS: MR imaging combined with colonography is a highly accurate tool for characterising deep endometriotic lesions in patients scheduled for laparoscopic surgery. In particular, MR colonography has very high accuracy in detecting colorectal involvement.

RÉSUMÉ

OBJECTIVE: To investigate the accuracy of transvaginal sonography (TVS) and contrast-enhanced magnetic resonance-colonography (CE-MR-C) for the presurgical assessment of deep infiltrating endometriosis (DIE). METHODS: Ninety women were enrolled prospectively for suspicion of DIE. All patients underwent TVS and CE-MR-C, with each operator blinded to the results of the other exam, before laparoscopy. The sites of DIE examined by both imaging techniques were: rectovaginal septum, pouch of Douglas, uterosacral ligaments, vesicouterine pouch, bowel, bladder and vagina. The presence of adhesions and the involvement of adnexa and of a previous abdominal scar, when there was clinical suspicion, were also evaluated. TVS and CE-MR-C findings were compared with laparoscopic and histological results. RESULTS: Endometriosis was confirmed by laparoscopy in 95.6% (86/90) of cases. In 82.2% (74/90) of patients there was DIE. The global accuracy for TVS in the detection of DIE was 89.2%, sensitivity was 81.1%, specificity was 94.2%, positive predictive value was 89.6%, negative predictive value was 89.0%, the positive likelihood ratio was 13.9 and the negative likelihood ratio was 0.2. For CE-MR-C, these values were 87.2%, 71.1%, 97.1%, 93.7%, 84.6%, 24.4 and 0.3, respectively. CE-MR-C allowed diagnosis of all cases of bowel involvement; the accuracy for infiltration and stenosis was 100%. The accuracy of TVS for rectosigmoid nodules was 91.1% and that for infiltration was 88.9%. CONCLUSIONS: Both TVS and CE-MR-C showed satisfactory results for the presurgical assessment of DIE. TVS appears to be a powerful, simple, feasible, cost-effective tool for preoperative staging of DIE. CE-MR-C is an 'X-ray free' technique, which could be reserved for cases with deep infiltrating rectosigmoid lesions and for the prediction of stenosis and involvement of the upper part of the colon and small intestine.

RÉSUMÉ

We assessed recent trends in hepatitis C virus (HCV) prevalence in pregnant women with HIV using data from a large national study. Based on 1240 pregnancies, we observed a 3.4-fold decline in HCV seroprevalence in pregnant women with HIV between 2001 (29.3%) and 2008 (8.6%). This decline was the net result of two components: a progressively declining HCV seroprevalence in non-African women (from 35.7% in 2001 to 16.7% in 2008), sustained by a parallel reduction in history of injecting drug use (IDU) in this population, and a significantly growing presence (from 21.2% in 2001 to 48.6% in 2008) of women of African origin, at very low risk of being HCV-infected [average HCV prevalence 1%, adjusted odds ratio (aOR) for HCV 0.09, 95% CI 0.03-0.29]. Previous IDU was the stronger determinant of HCV co-infection in pregnant women with HIV (aOR 30.9, 95% CI 18.8-51.1). The observed trend is expected to translate into a reduced number of cases of vertical HCV transmission.

RÉSUMÉ

AIM: Consistent modifications of socio-economic factors may represent crucial non-clinical determinants for the rising rate of caesarean section among primiparae. This increasing trend has been reported in many countries and its relationship with social modifications is widely accepted, though poorly supported by published data. METHODS: Population-based social and economic data were analyzed between two study periods 30 years apart (1971 vs 2001). RESULTS: The number of births dropped dramatically within the study period (about -40%). Italian women tend to delay childbearing (25.1 vs 28.8 years of age at first delivery) to pursue a career and a later marriage and motherhood lead to a contraction of the number of members of the family. Older mothers are at higher risk of caesarean (treble over 40 years of age), especially those with high career position. Health expenditures increased significantly between 1971 and 2001. A progressive contraction of the number of women in reproductive age is expected in the next 50 years in Italy. CONCLUSION: Many determinants are involved in the choice of a caesarean section and most of these are not strictly medical. The rapidly mounting number of legal claims may indeed lead to defensive practices. Given these data, a reduction of caesarean section rate seems unlikely to be achieved at present.

RÉSUMÉ

BACKGROUND/AIMS: Extreme preterm birth, <28 weeks of gestation, represents a public health concern with major economic implications, being the leading cause of neonatal mortality and morbidity. METHODS: A single-centre retrospective cohort study was carried out to assess the role of caesarean section and to identify perinatal factors affecting neonatal survival and psychomotor development in these infants. 57 cases with complete maternal, obstetrical and neonatological information were selected for this study and neurological development was assessed for at least 18 months of life. RESULTS: Infant survival and neurological morbidity rates were directly and inversely correlated to birth weights and gestational age at birth, respectively. In multivariate analysis only extreme prematurity (

RÉSUMÉ

OBJECTIVE: The accuracy of current formulae for the sonographic estimation of fetal weight (EFW) is compromised by significant intra- and interobserver variability of biometrical measurements, particularly circumferences. The aim of this study was to assess the reliability of the linear measurement of mid-thigh soft-tissue thickness (STT) and to derive a novel formula for EFW. METHODS: This was a prospective study involving 388 singleton uncomplicated pregnancies. There were three consecutive phases: (1) to verify the relationship between STT and birth weight, (2) to derive a novel formula for EFW using femur length and STT only, and (3) to test the accuracy of the new equation. Only the 290 patients who delivered within 48 h of measurement were considered for the analysis. A comparison with other formulae was performed. RESULTS: STT was significantly correlated with both abdominal circumference and birth weight (r(2) = 0.36 and 0.46, respectively; P < 0.001). Both intra- and interobserver variability were satisfactory (0.44 +/- 0.27 and 0.57 +/- 0.35 mm, respectively). The equation for EFW was developed using multiple stepwise regression analysis (EFW = - 1687.47 + (54.1 x femur length) + (76.68 x STT)) and tested prospectively on 69 patients. The new formula yielded results (r = 0.79) that were slightly better in accuracy than two other published equations, and had an absolute mean error of < 15% in 97% of cases. CONCLUSIONS: Our findings confirm the potential of the linear measurement of mid-thigh STT as a valuable parameter for the sonographic assessment of fetal growth and EFW. Our new equation is apparently at least as reliable as the most widely used formulae for EFW.

RÉSUMÉ

BACKGROUND: The clinical relevance of antiphospholipid antibodies (aPL) in women undergoing in vitro fertilization/embryo transfer (IVF/ET) and the role of IVF treatment in affecting antiphospholipid levels are controversial. The aim of this study was to evaluate anticardiolipin antibody (aCL) levels and the effect of IVF treatment on aCL in women undergoing their first IVF/ET cycle. METHODS: Immunoglobulin G (IgG)- and IgM-aCL were determined by enzyme-linked immunosorbent assay in 50 women undergoing IVF/ET, 18 due to endometriosis, 16 to tubal factor (TF) and 16 to male factor, before starting treatment (T0), on the day of oocyte retrieval (T1) and 14 days after ET (T2). A group of 31 age-matched fertile women served as controls. RESULTS: aCL levels detected at T0 in patients were not significantly different compared with the control group. IgG- but not IgM-aCL significantly increased at T2 in comparison with T0 (P < 0.001) and T1 (P < 0.05). The difference between T2 and T0 reached statistical significance in patients with endometriosis (P = 0.003) or TF (P = 0.018). No relationship was found between aCL and pregnancy. CONCLUSIONS: Our results indicate that IVF treatment increases IgG-aCL levels in patients with endometriosis and TF, but their presence seems to have no clinical relevance.

RÉSUMÉ

We analysed the characteristics of the pregnancies with a previously undetected HIV infection in a national observational study of pregnant women with HIV in Italy. In a total of 443 pregnancies with available date of HIV diagnosis, 118 were characterized by a previously undetected HIV infection (26.6%, 95% CI 22.5-30.8). The following factors were independently associated with this occurrence in a multivariate analysis (adjusted odds ratios; 95% CIs): foreign nationality (5.1, 2.8-9.3); no pre-conception counselling (35.9, 4.8-266.1); first pregnancy (2.1, 1.2-4.0); asymptomatic status (6.8, 1.5-30.6). Women with previously undetected infection started antiretroviral treatment significantly later during pregnancy (P < 0.001). Missed diagnosis was responsible for one case of transmission. A high rate of previously undetected HIV infection was observed. This suggests a good HIV detection during pregnancy, but also the need to reinforce HIV testing strategies among women of childbearing age. We identified some determinants which may be considered for intervention measures.

RÉSUMÉ

BACKGROUND: Human immunodeficiency virus (HIV)-infected patients are more predisposed than HIV-negative women to develop squamous intraepithelial lesions (SIL) of the uterine cervix, and cervical dysplasia may be of higher grade in HIV-positive women than in HIV-negative subjects, with more extensive and multi-centric involvement of the lower genital tract by human papillomavirus (HPV)-associated lesions. Moreover, recurrence and progression rate of cervical intraepithelial neoplasia (CIN) is particularly higher in immunocompromised women. DESIGN: Retrospective case-control study of HIV-positive women and HIV-negative controls, all affected by low-grade SIL of the uterine cervix, treated by loop excision or followed-up without treatment. Correlation of progression and recurrence of SIL with HIV status and CD4+ count. PATIENTS: From September 1990 to October 1997, 75 HIV-positive low-grade-SIL patients, 47 treated and 28 followed-up without treatment, and 75 HIV-negative low-grade-SIL controls, 45 treated and 30 followed-up. RESULTS: Among treated patients, 17/47 (36.2%) HIV-positive and 5/45 (11.1%) controls had recurrence (P < 0.0101, O.R. = 4.53, 95% CI = 1.5-13.7), progression of untreated lesion was seen in 15/28 (53.6%) HIV-positive and 7/30 (23%) controls (P < 0.05, O.R. = 3.79, 95% CI = 1.23-11.69). The risk of recurrence or progression of low-grade SIL linked to HIV seropositivity is about 4-5 times higher in comparison with seronegative counterpart, matched for age, risk factors and lesion size. More significantly, considering the cut-off of 200 CD4+/mm(3) in HIV-positive women, 13/17 cases of recurrence (P < 0.05, O.R. = 4.88, 95% CI = 1.28-18.58) and 10/15 cases with progression (P < 0.05, O.R. = 6.67, 95% CI = 1.24-35.73) were immunocompromised (<200 CD4+/mm3), with a significant higher risk of recurrence or progression linked to immunodeficiency status. Considering time of progression or recurrence, during follow-up, Kaplan-Meier curves shows that HIV-positive status and immunodeficiency are correlated with more rapid evolution of cervical dysplasia and HPV-related lesions: comparison of recurrence in treated patients report P < 0.005 and progression in untreated P<0.05 (Mantel-Haenszel log-rank test). CONCLUSIONS: Immunological status seems to be a determinant factor in prognosis of cervical SIL, HIV-positive women affected by this lesion, even if low-grade, need more aggressive management than the immunocompetent counterpart. Strict cytologic and colposcopic screening is recommended and CD4+ count and HPV-DNA testing may be useful risk indicators. Excisional procedures are preferred, while ablative treatments or wait and see policy may expose to some risk this type of population with poor compliance to follow-up.

RÉSUMÉ

AIM: Prevention and treatment of congenital toxoplasmosis are still a matter of debate among obstetricians, pediatricians and epidemiologists. There is no consensus about antenatal screening and diagnostic tests, nor there is about treatment for presumed infection in pregnancy. As an example of this type of organisation for health care delivery, a regional model has been promoted as a multidisciplinary approach for prenatal diagnosis of congenital toxoplasmosis. The model had been designed on the national guidelines of the National Health Institute (Istituto Superiore di Sanità, ISS). METHODS: Suspected maternal infections are referred and seen as outpatients at our centre on a specific day of the week; maternal investigation (specific IgG, IgM, IgA and IgG avidity titres) are performed at the Institute of Virology of the University of Bari, and patients are started on spiramycin. All cases of true or presumed seroconversion are counselled for amniotic fluid sampling and the sample is sent to ISS. In cases of late seroconversion and positive amniotic fluid results, patients are prescribed pyrimethamine+sulphonamide+folinic acid and alternate spiramycin until the end of pregnancy. A fetal-neonatal follow-up is performed in all cases. RESULTS: During the period 1999-2001, 180 cases of presumed toxoplasmosis infection have been referred (average 60 cases per year). We have been able to reclute, since the adoption of the national network protocol, 1/3 of presumed regional cases with a positive increasing trend. CONCLUSION: The service for prenatal diagnosis of toxoplasma gondii infection has definitely benefitted from the adoption of this protocol, which combines adherence to a national network and pays respect to regional requirements.

RÉSUMÉ

OBJECTIVES: The aim of the study was to correlate the Ki-67 and cyclin A labelling index (LI) with clinical characteristics and risk of recurrence of craniopharyngiomas. METHODS: 47 consecutive patients were studied, 21 female and 26 male, aged 34.3 (2.8) years. Immunohistochemical analysis was performed on paraffin wax embedded material using monoclonal antibodies directed against the proliferation associated nuclear antigen Ki-67 and cyclin A. RESULTS: The median Ki-67 LI was 8.6% (interquartile range, 4.4%-14.0%). Ki-67 LI was significantly higher in tumours with a heavy inflammatory reaction and diabetes insipidus at presentation, whereas other clinical and histological features were not associated with the proliferation index. There was a strong linear correlation between Ki-67 LI and cyclin A LI (r = 0.77; p<0.0001); therefore, cyclin A LI showed the same clinical and histological relations described for Ki-67 LI. Recurrence of craniopharyngioma occurred in 13 of 46 patients (28.3%). The median Ki-67 LI in the 13 recurrent craniopharyngiomas (9.0%) was not significantly different from that of non-recurring tumours (7.9%). Cyclin A LI was also not associated with the risk of relapse. CONCLUSIONS: This study confirms the great variability of proliferative activity in craniopharyngiomas. Ki-67 and cyclin A LIs were associated with the presence of a heavy inflammatory reaction and diabetes insipidus, but did not correlate with the long term risk of tumour regrowth.
