Abstract
OBJECTIVE To determine the diagnostic accuracy of prenatal ultrasound in detecting coarctation of the aorta (CoA). METHODS An individual participant data meta-analysis was performed to report on the strength of association and diagnostic accuracy of different ultrasound signs in detecting CoA prenatally. MEDLINE, EMBASE and CINAHL were searched for studies published between January 2000 and November 2021. Inclusion criteria were fetuses with suspected isolated CoA, defined as ventricular and/or great vessel disproportion with right dominance on ultrasound assessment. Individual participant-level data were obtained by two leading teams. PRISMA-IPD and PRISMA-DTA guidelines were used for extracting data, and the QUADAS-2 tool was used for assessing quality and applicability. The reference standard was CoA, defined as narrowing of the aortic arch, diagnosed after birth. The most commonly evaluated parameters on ultrasound, both in B-mode and on Doppler, constituted the index test. Summary estimates of sensitivity, specificity, diagnostic odds ratio (DOR) and likelihood ratios were computed using the hierarchical summary receiver-operating-characteristics model. RESULTS The initial search yielded 72 studies, of which 25 met the inclusion criteria. Seventeen studies (640 fetuses) were included. On random-effects logistic regression analysis, tricuspid valve/mitral valve diameter ratio > 1.4 and > 1.6, aortic isthmus/arterial duct diameter ratio < 0.7, hypoplastic aortic arch (all P < 0.001), aortic isthmus diameter Z-score of < -2 in the sagittal (P = 0.003) and three-vessel-and-trachea (P < 0.001) views, pulmonary artery/ascending aorta diameter ratio > 1.4 (P = 0.048) and bidirectional flow at the foramen ovale (P = 0.012) were independently associated with CoA. Redundant foramen ovale was inversely associated with CoA (P = 0.037). Regarding diagnostic accuracy, tricuspid valve/mitral valve diameter ratio > 1.4 had a sensitivity of 72.6% (95% CI, 48.2-88.3%), specificity of 65.4% (95% CI, 46.9-80.2%) and DOR of 5.02 (95% CI, 1.82-13.9). The sensitivity and specificity values were, respectively, 75.0% (95% CI, 61.1-86.0%) and 39.7% (95% CI, 27.0-53.4%) for pulmonary artery/ascending aorta diameter ratio > 1.4, 47.8% (95% CI, 14.6-83.0%) and 87.6% (95% CI, 27.3-99.3%) for aortic isthmus diameter Z-score of < -2 in the sagittal view and 74.1% (95% CI, 58.0-85.6%) and 62.0% (95% CI, 41.6-78.9%) for aortic isthmus diameter Z-score of < -2 in the three-vessel-and-trachea view. Hypoplastic aortic arch had a sensitivity of 70.0% (95% CI, 42.0-88.6%), specificity of 91.3% (95% CI, 78.6-96.8%) and DOR of 24.9 (95% CI, 6.18-100). The diagnostic yield of prenatal ultrasound in detecting CoA did not change significantly when considering multiple categorical parameters. Five of the 11 evaluated continuous parameters were independently associated with CoA (all P < 0.001) but all had low-to-moderate diagnostic yield. CONCLUSIONS Several prenatal ultrasound parameters are associated with an increased risk for postnatal CoA. However, diagnostic accuracy is only moderate, even when combinations of parameters are considered. © 2024 The Authors.

Abstract
OBJECTIVES To determine the incremental diagnostic yield of exome sequencing (ES) after negative chromosomal microarray analysis (CMA) in cases of prenatally diagnosed agenesis of the corpus callosum (ACC) and to identify the associated genes and variants. METHODS A systematic search was performed to identify relevant studies published up until June 2022 using four databases: PubMed, SCOPUS, Web of Science and The Cochrane Library. Studies in English reporting on the diagnostic yield of ES following negative CMA in prenatally diagnosed partial or complete ACC were included. Authors of cohort studies were contacted for individual participant data and extended cohorts were provided for two of them. The increase in diagnostic yield with ES for pathogenic/likely pathogenic (P/LP) variants was assessed in all cases of ACC, isolated ACC, ACC with other cranial anomalies and ACC with extracranial anomalies. To identify all reported genetic variants, the systematic review included all ACC cases; however, for the meta-analysis, only studies with ≥ three ACC cases were included. Meta-analysis of proportions was employed using a random-effects model. Quality assessment of the included studies was performed using modified Standards for Reporting of Diagnostic Accuracy criteria. RESULTS A total of 28 studies, encompassing 288 prenatally diagnosed ACC cases that underwent ES following negative CMA, met the inclusion criteria of the systematic review. We classified 116 genetic variants in 83 genes associated with prenatal ACC with a full phenotypic description. There were 15 studies, encompassing 268 cases, that reported on ≥ three ACC cases and were included in the meta-analysis. Of all the included cases, 43% had a P/LP variant on ES. The highest yield was for ACC with extracranial anomalies (55% (95% CI, 35-73%)), followed by ACC with other cranial anomalies (43% (95% CI, 30-57%)) and isolated ACC (32% (95% CI, 18-51%)). CONCLUSIONS ES demonstrated an incremental diagnostic yield in cases of prenatally diagnosed ACC following negative CMA. While the greatest diagnostic yield was observed in ACC with extracranial anomalies and ACC with other central nervous system anomalies, ES should also be considered in cases of isolated ACC. © 2023 The Authors.

Abstract
OBJECTIVE To quantify the rate of perinatal mortality in monochorionic monoamniotic (MCMA) twin pregnancies, according to gestational age, and to ascertain the incidence of mortality in pregnancies managed as inpatients compared with those managed as outpatients. METHODS MEDLINE, EMBASE and CINAHL databases were searched for studies on monoamniotic twin pregnancy. The primary outcomes explored were the incidence of intrauterine death (IUD), neonatal death (NND) and perinatal death (PND) in MCMA twins at different gestational-age windows (24-30, 31-32, 33-34, 35-36 and ≥ 37 weeks of gestation). The secondary outcomes were the incidence of IUD, NND and PND in MCMA twins according to the type of fetal monitoring (inpatient vs outpatient), and the incidence of delivery ahead of schedule. Random-effects model meta-analyses were used to analyze the data. RESULTS Twenty-five studies (1628 non-anomalous twins reaching 24 weeks of gestation) were included. Single and double intrauterine deaths occurred in 2.5% (95% CI, 1.8-3.3%) and 3.8% (95% CI, 2.5-5.3%) of cases, respectively. IUD occurred in 4.3% (95% CI, 2.8-6.2%) of twins at 24-30 weeks, in 1.0% (95% CI, 0.6-1.7%) at 31-32 weeks and in 2.2% (95% CI, 0.9-3.9%) at 33-34 weeks of gestation, while there was no case of IUD, either single or double, from 35 weeks of gestation. In MCMA twin pregnancies managed mainly as inpatients, the incidence of IUD was 3.0% (95% CI, 1.4-5.2%), while the corresponding figure for those managed mainly as outpatients was 7.4% (95% CI, 4.4-11.1%). Finally, 37.8% (95% CI, 28.0-48.2%) of MCMA pregnancies were delivered before the scheduled time, due mainly to spontaneous preterm labor or abnormal cardiotocographic findings. CONCLUSIONS MCMA twins are at high risk of perinatal loss during the third trimester of pregnancy, with the large majority of such losses occurring as apparently unexpected events. Inpatient management seems to be associated with a lower rate of mortality, although further studies are needed in order to establish the appropriate type and timing of prenatal assessment in these pregnancies.

Abstract
OBJECTIVE To assess the predictive value of sonographic cervical-length (CL) measurement in mid-gestation for spontaneous preterm birth (PTB) in asymptomatic triplet pregnancy. METHODS This was a retrospective study of asymptomatic triplet pregnancies followed at five Italian tertiary referral centers, between 2002 and 2015. CL was measured transvaginally between 18 and 24 weeks' gestation. Pregnancies with medically indicated PTB were excluded. Demographic and pregnancy characteristics of pregnancies complicated by PTB were analyzed and the distributions of CL measurements in these patients were calculated. Logistic regression analysis was performed to assess the association between CL and PTB, adjusted for confounders. Performance of CL measurement in prediction of PTB < 28, < 30 and < 32 weeks of gestation was assessed. RESULTS A total of 120 triplet pregnancies were included in the final analysis. Median CL was 35 (interquartile range (IQR), 29-40) mm measured at a median gestational age of 20 + 2 (IQR, 20 + 0 to 23 + 4) weeks. Overall, 23 (19.2%), 17 (14.2%) and eight (6.7%) patients had a CL < 25, < 20 and < 15 mm, respectively. Spontaneous PTB < 32 weeks occurred in 41 (34.2%) cases, < 30 weeks in 23 (19.2%) and < 28 weeks in 12 (10%) cases. CL < 15 mm was significantly more frequent in the group of patients who delivered < 28 (P = 0.03) and < 30 (P = 0.01) weeks' gestation, compared with those who delivered after 28 and after 30 weeks, respectively, while CL < 20 mm was more common in triplet pregnancies with delivery < 32 weeks compared with those delivered ≥ 32 weeks (P = 0.03). Logistic regression analysis was possible only for PTB < 32 weeks due to the small number of cases that delivered < 30 and < 28 weeks. After adjustment for confounders, CL was not significantly associated with PTB < 32 weeks (adjusted odds ratio, 0.97; 95% CI, 0.94-1.01). CL measurement had an area under the receiver-operating characteristics curve of 0.41 (95% CI, 0.20-0.62), 0.41 (95% CI, 0.26-0.56) and 0.42 (95% CI, 0.31-0.54) for the prediction of spontaneous PTB < 28, < 30 and < 32 weeks, respectively. CONCLUSION CL assessed in mid-gestation is a poor predictor of PTB < 28, < 30 and < 32 weeks' gestation in asymptomatic triplet pregnancy. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
In a prospective trial conducted by the Gruppo Onco Urologico Piemontese, newly diagnosed prostate cancer patients with bone metastases were randomized to receive goserelin (3.6 mg subcutaneously every 4 weeks) or goserelin plus mitomycin at 14 mg/m2 i.v. every 6 weeks. Treatment was planned to be continued until progression. The study was interrupted because of inadequate accrual rate when 63 patients had been recruited. A long-term follow-up (median, 47 months), performed to counterbalance the limited number of patients included, revealed no difference in time to progression and overall survival between the study treatments. However, 56.5% of assessable patients allocated to the chemotherapy arm presented a ≥90% reduction of prostate-specific antigen levels compared with 36.3% in the goserelin group, and previously elevated levels normalized in 73.9% versus 45.4%. Non-progressing patients received 5-7 cycles of mitomycin C with acceptable toxicity, but the cytotoxic treatment was interrupted early in all cases within the first year due to cumulative myelotoxicity. In conclusion, the results, although inconclusive, fail to support a clear advantage in terms of cost/benefit of chemotherapy plus hormone therapy over hormone treatment alone in advanced prostate cancer with bone involvement.

Abstract
OBJECTIVE To explore the outcome of monochorionic twin pregnancies affected by selective intrauterine growth restriction (sIUGR) according to the umbilical artery Doppler pattern of the smaller twin. METHODS An electronic search of MEDLINE, EMBASE, CINAHL and ClinicalTrials.gov databases (2000-2016) was performed. sIUGR was defined as the presence of one twin with an estimated fetal weight and/or abdominal circumference < 10th or < 5th percentile and classified according to the umbilical artery Doppler flow pattern of the smaller twin (Type I: persistently positive; Type II: persistently absent/reversed; Type III: intermittently absent/reversed). Primary outcomes were perinatal mortality, intrauterine death, neonatal death and double fetal loss. Secondary outcomes were neonatal morbidity, including abnormal postnatal brain imaging, intraventricular hemorrhage, periventricular leukomalacia, admission to neonatal intensive care unit and respiratory distress syndrome, deterioration of fetal status, gestational age at delivery and degree of birth-weight discordance. A composite adverse outcome, defined as the presence of any mortality or abnormal brain findings, was also assessed. Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was used to compute the summary odds ratios (ORs), mean differences (MD) and proportions for the different outcomes. RESULTS Thirteen studies (610 pregnancies) were included. The risk of perinatal mortality was higher in twins affected by Type II compared with Type I sIUGR (OR, 4.1 (95% CI, 1.6-10.3)), whereas there was no difference among the other variants of growth restriction. Risk of abnormal postnatal brain imaging was significantly higher in twins affected by either Type II (OR, 4.9 (95% CI, 1.9-12.9)) or Type III (OR, 8.2 (95% CI, 2.0-33.1)) sIUGR compared with Type I sIUGR. The risk for neonatal intensive care unit admission was higher in Type II compared with Type I sIUGR (OR, 18.3 (95% CI, 1.0-339.7)). Twin pregnancies affected by Type I sIUGR were delivered at a significantly later gestational age compared with Type II (MD, 2.8 (95% CI, 1.83-3.86) weeks) and Type III (MD, 2.1 (95% CI, 0.97-3.19) weeks). The degree of birth-weight discordance was higher in Type II compared with Type I (MD, 21.6% (95% CI, 9.9-33.2%)) and Type III (MD, 9.3% (95% CI, 3.8-14.9%)) sIUGR. CONCLUSION Monochorionic twin pregnancies affected by Type II sIUGR are at a higher risk of perinatal mortality and morbidity compared with Type I. The likelihood of an abnormal outcome is usually not significantly different between sIUGR Types II and III, although the latter has an unpredictable clinical course. Copyright © 2016 ISUOG.

Abstract
OBJECTIVE To investigate the diagnostic performance of ultrasound in predicting birth-weight (BW) discordance in twin pregnancy. METHODS Electronic databases PubMed, EMBASE and CINAHL were searched using combinations of MeSH terms 'birth weight', 'discordance', 'twins' and 'ultrasound'. Summary estimates of sensitivity, specificity, positive and negative likelihood ratios and diagnostic odds ratios for the predictive accuracy of sonographically estimated fetal-weight (EFW) discordance and abdominal-circumference (AC) discordance in predicting BW discordance were computed using hierarchical summary receiver-operating characteristics curves. RESULTS Twenty studies (including 5826 twin pregnancies) were included. EFW discordance ≥ 20% had a sensitivity of 65.4% and specificity of 90.8% in predicting BW discordance ≥ 20%. The predictive performance of ultrasound performed within 1 month, 2 weeks and 3 days before birth was 61.4%, 72.3% and 78.9%, respectively. EFW discordance ≥ 25% had a sensitivity of 57.7% and specificity of 95.2% in predicting BW discordance ≥ 25%. The sensitivity of EFW discordance ≥ 25% detected within 1 month, 2 weeks and 3 days before birth was 60.0%, 75.0% and 60.3%, respectively, while the corresponding values for specificity were 97.7%, 96.2% and 87.3%, respectively. In view of the different cut-offs reported among studies, it was not possible to perform comprehensive data synthesis for each AC discordance cut-off. The optimal diagnostic performance of AC discordance was for prediction of BW discordance ≥ 25%, with a sensitivity of 70.8% and specificity of 86.4%. CONCLUSION Ultrasound EFW discordance has an overall moderate accuracy in predicting BW discordance in twin pregnancy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE To explore the outcome of fetuses with a prenatal diagnosis of ovarian cyst. METHODS The electronic databases MEDLINE and EMBASE were searched using keywords and word variants for 'ovarian cysts', 'ultrasound' and 'outcome'. The following outcomes in fetuses with a prenatal diagnosis of ovarian cyst were explored: resolution of the cyst, change of ultrasound pattern of the cyst, occurrence of ovarian torsion and intracystic hemorrhage, need for postnatal surgery, need for oophorectomy, accuracy of prenatal ultrasound examination in correctly identifying ovarian cyst, type of ovarian cyst at histopathological analysis and intrauterine treatment. Meta-analyses using individual data random-effects logistic regression and meta-analyses of proportions were performed. Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale. RESULTS Thirty-four studies (954 fetuses) were included. In 53.8% (95% CI, 46.0-61.5%) of cases for which resolution of the cyst was evaluated (784 fetuses), the cyst regressed either during pregnancy or after birth. The likelihood of resolution was significantly lower in complex vs simple cysts (odds ratio (OR), 0.15 (95% CI, 0.10-0.23)) and in cysts measuring ≥ 40 mm vs < 40 mm (OR, 0.03 (95% CI, 0.01-0.06)). Change in ultrasound pattern of the cyst was associated with an increased risk of ovarian loss (surgical removal or autoamputation) (pooled proportion, 57.7% (95% CI, 42.9-71.8%)). The risk of ovarian torsion was significantly higher for cysts measuring ≥ 40 mm compared with < 40 mm (OR, 30.8 (95% CI, 8.6-110.0)). The likelihood of having postnatal surgery was higher in patients with cysts ≥ 40 mm compared with < 40 mm (OR, 64.4 (95% CI, 23.6-175.0)) and in complex compared with simple cysts, irrespective of cyst size (OR, 14.6 (95% CI, 8.5-24.8)). In cases undergoing prenatal aspiration of the cyst, rate of recurrence was 37.9% (95% CI, 14.8-64.3%), ovarian torsion and intracystic hemorrhage were diagnosed after birth in 10.8% (95% CI, 4.4-19.7%) and 12.8% (95% CI, 3.8-26.0%), respectively, and 21.8% (95% CI, 0.9-40.0%) had surgery after birth. CONCLUSION Size and ultrasound appearance are the major determinants of perinatal outcome in fetuses with ovarian cysts. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE To assess the role of first- and early second-trimester markers in the prediction of twin-to-twin transfusion syndrome (TTTS) in monochorionic twin pregnancies. METHODS Electronic databases MEDLINE, EMBASE and ClinicalTrials.gov were searched from inception to April 2014, using the MeSH term 'fetofetal transfusion' in combination with phrases 'predictive value', 'sensitivity', 'specificity', 'false positive', 'false negative', 'screening', 'accuracy' and 'ROC'. Study quality was assessed using the PRISMA guidelines and QUADAS-2 tool. A meta-analysis was planned for the following predictive factors: intertwin nuchal translucency (NT) discrepancy; NT > 95th percentile in at least one twin; intertwin crown-rump length (CRL) discrepancy as a percentage of the larger CRL; abnormal ductus venosus (DV) flow in at least one twin. The outcome assessed was TTTS, defined according to the presence of a twin oligohydramnios-polyhydramnios sequence. The diagnostic performance of the predictive factors was evaluated for each included study. RESULTS The electronic search identified 152 records, of which 23 were assessed in full for eligibility. We identified 13 eligible studies that reported the predictive accuracy of ultrasound parameters, measured before 16 weeks, for the development of TTTS, including a total of 1991 pregnancies, of which 323 developed TTTS. An increased risk of TTTS was associated with: intertwin NT discrepancy (positive likelihood ratio (LR+), 1.92 (95% CI, 1.25-2.96); negative likelihood ratio (LR-), 0.65 (95% CI, 0.50-0.84)); NT > 95th percentile (LR+, 2.63 (95% CI, 1.51-4.58); LR-, 0.85 (95% CI, 0.75-0.96)); CRL discrepancy > 10% (LR+, 1.80 (95% CI, 1.05-3.07); LR-, 0.92 (95% CI, 0.81-1.05)); abnormal DV flow (LR+, 4.77 (95% CI, 1.33-17.04; LR-, 0.49 (95% CI, 0.17-1.41)). The highest sensitivities were observed for intertwin NT discrepancy (52.8% (95% CI, 43.8-61.7%)) and abnormal DV flow (50.0% (95% CI, 33.4-66.6%)). CONCLUSION Monochorionic twin pregnancies with intertwin NT discrepancy, NT > 95th percentile, intertwin CRL discrepancy > 10% or abnormal DV flow on first-trimester ultrasound examination are at significantly increased risk of developing TTTS.

Abstract
OBJECTIVES To assess the role of intertwin discrepancy in middle cerebral artery peak systolic velocity (MCA-PSV) for the prediction of late selective intrauterine growth restriction (sIUGR) at birth and birth weight discrepancy of > 25% (BW-25) in otherwise uncomplicated monochorionic-diamniotic (MCDA) twin pregnancies. METHODS This was a cohort study including all MCDA pregnancies followed in a tertiary fetal medicine unit between 2008 and 2013. Exclusion criteria were referral after first trimester, abnormal karyotype, structural anomalies, twin-to-twin transfusion syndrome, twin anemia-polycythemia sequence and sIUGR detected before 28 weeks. MCA-PSV values of both twins measured in the second trimester (18-24 weeks) and early third trimester (26-32 weeks) were converted in multiples of the median (MoM). sIUGR was defined as birth weight < 5(th) centile. The relationship between MCA-PSV discrepancy, sIUGR and BW-25 was assessed by logistic regression analysis. Receiver-operating characteristics (ROC) curves were used to ascertain the predictive value of MCA-PSV discrepancy for such complications. RESULTS In total, 136 MCDA twin pregnancies were included in the analysis. Thirty (22.1%) were complicated with sIUGR at birth and 12 (8.8%) were complicated with BW-25. Logistic regression analysis identified MCA-PSV discrepancy as an independent predictor for sIUGR. ROC curves identified third-trimester MCA-PSV discrepancy as the best predictor for both sIUGR (area under ROC curve (AUC), 0.73 (95% CI, 0.62-0.85)) and BW-25 (AUC, 0.79 (95% CI, 0.65-0.93)). The optimal cut-off point for MCA-PSV discrepancy was 0.30 MoM (sensitivity, 70% and specificity, 69% for sIUGR; sensitivity, 83% and specificity, 72% for BW-25). CONCLUSION In MCDA twin pregnancies, MCA-PSV discrepancy is associated with both sIUGR at birth and BW discordance. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE Short cervical length (CL) in mid-gestation is considered predictive of spontaneous preterm birth (PTB). The medical literature suggests 20 mm as the cut-off for high risk in twin pregnancies. Our objective was to assess the predictive value of CL for spontaneous PTB < 32 weeks' gestation in twin pregnancies and to calculate the cut-off point with the best sensitivity and specificity. METHODS This was a single-center retrospective cohort study of women in whom CL had been measured by transvaginal ultrasound at 18-23 weeks' gestation. Pregnancies complicated by twin-to-twin transfusion syndrome, those requiring intrauterine therapy or those with indicated PTB were excluded. The predictive value of CL for PTB < 32 weeks was assessed. The distribution of CL measurements and the optimal cut-off in patients with PTB were calculated and logistic regression analysis was performed to assess the association between pregnancy characteristics and PTB. RESULTS A total of 940 twin pregnancies were included. CL showed an area under the receiver-operating characteristics curve of 0.65 (95% CI, 0.58-0.71) for the prediction of PTB < 32 weeks. The optimal cut-off value for predicting PTB was 36 mm (sensitivity, 64.1%; specificity, 62.8%; positive predictive value, 13.5%; negative predictive value, 95.1%; accuracy, 62.9%). The relative risk of PTB with CL ≤ 36 mm was 2.35 (95% CI, 1.53-3.60; P < 0.001). After adjusting for confounders in logistic regression analysis, only CL (adjusted odds ratio (aOR), 0.94 (95% CI, 0.90-0.99); P = 0.03), and not monochorionicity (aOR 4.14 (95% CI, 0.89-19.25); P = 0.07), was independently associated with PTB. More than one-third (36%) of PTB cases delivering < 32 weeks had a normal CL in mid-gestation. This proportion rose to 85% when considering the 20-mm cut-off suggested by the medical literature. CONCLUSIONS This study shows that, despite the weak independent association, CL assessed in mid-gestation is a poor predictor of PTB < 32 weeks' gestation in asymptomatic twin pregnancies.

Abstract
OBJECTIVES The finding of fetal ventriculomegaly is variably associated with other fetal abnormalities and, even when isolated, is thought to be linked to abnormal neurodevelopmental outcome. The aim of this study was to undertake a systematic review and meta-analysis of the current literature to assess the prevalence of neurodevelopmental delay in cases of isolated mild fetal ventriculomegaly, as well as the false-negative rate of prenatal imaging for the diagnosis of associated abnormalities in patients referred for isolated mild ventriculomegaly. METHODS Studies that assessed neurodevelopmental outcome in isolated ventriculomegaly were identified from a search of scientific databases. Studies that did not check for karyotype or that excluded cases of bilateral ventriculomegaly were not included in the analysis. Ventriculomegaly was defined as mild when the width of the ventricular atrium was between 10 and 15 mm. Cases in which an associated abnormality (abnormal karyotype, structural abnormality or fetal infection) was observed either before or after birth were not considered as part of the isolated group. Neurodevelopmental delay was defined as an abnormal quotient score, according to the test used. RESULTS The search yielded 961 possible citations; of these, 904 were excluded by review of the title or abstract as they did not meet the selection criteria. Full manuscripts were retrieved for 57 studies, and 20 were included in the review with a total of 699 cases of isolated mild ventriculomegaly. The overall prevalence of neurodevelopmental delay was 7.9% (95% CI, 4.7-11.1%). Of the 20 studies included in the systematic review, nine reported data on postnatal imaging, showing a prevalence of previously undiagnosed findings of 7.4% (95% CI, 3.1-11.8%). CONCLUSIONS The false-negative rate of prenatal imaging is 7.4% in apparently isolated fetal ventriculomegaly of ≤ 15 mm. The incidence of neurodevelopmental delay in truly isolated ventriculomegaly of ≤ 15 mm is 7.9%. As the latter rate is similar to that noted in the general population, large prospective cohort studies assessing the prevalence of childhood disability, rather than subtle neurodevelopmental delay, are required.

Abstract
OBJECTIVE The aim of this systematic review was to explore the relationship between crown-rump length (CRL) discordance detected at 11-14 weeks of gestation and adverse outcome in twin pregnancy and to assess its predictive accuracy. METHODS A protocol designed a priori following MOOSE guidelines and recommended for systematic review and meta-analysis was used. The outcomes observed were: total fetal and perinatal loss, fetal loss at <24 weeks, fetal loss at ≥ 24 weeks, birth-weight (BW) discordance, preterm delivery (PTD) at < 34 weeks and fetal anomalies. The analysis was performed for all twins and for dichorionic (DC) and monochorionic (MC) twins separately. RESULTS A total of 2008 articles were identified and 17 studies were included in the systematic review. Twin pregnancies with CRL discordance ≥ 10% were at significantly higher risk of perinatal loss (RR, 2.80; 95% CI, 1.25-6.27; P = 0.012), fetal loss at ≥ 24 weeks (RR, 4.07; 95% CI, 1.47-11.23; P = 0.006), BW discordance (RR, 2.24; 95% CI, 1.89-2.64; P < 0.001) and PTD at < 34 weeks (RR, 1.49; 95% CI, 1.23-1.80; P < 0.001) but not of fetal loss at < 24 weeks (P = 0.130). A meta-analysis of fetal anomalies was not possible because fewer than two studies explored this outcome. However, when used alone to screen for adverse pregnancy outcome, the predictive accuracy of CRL discordance was low for each of the outcomes explored. CONCLUSION CRL discordance is associated with an increased risk of adverse pregnancy outcome. However, the accuracy of CRL discordance in predicting adverse outcome is poor and thus limits its routine use in clinical practice.

Abstract
OBJECTIVES To evaluate the association between second-trimester uterine artery (UtA) Doppler pulsatility index (PI) with reduced fetal movements (RFM) and adverse pregnancy outcome at term. METHODS This was a retrospective cohort study of all singleton pregnancies referred for routine antenatal care at a fetal medicine unit over a 5-year period. UtA Doppler indices were obtained at the time of the routine anomaly scan between 19 and 23 weeks' gestation to assess the risk for pre-eclampsia. All episodes of RFM within 1 month of the expected date of delivery were recorded. Regression and sensitivity analyses were used to assess the relationship between UtA-PI with RFM, small-for-gestational-age (SGA) fetuses and stillbirth after 36 weeks' gestation. RESULTS Overall, 17, 649 pregnancies were included in the analysis, of which 742 presented with RFM, 1494 gave birth to an SGA newborn and 53 were complicated by stillbirth after 36 weeks' gestation. Logistic regression analysis showed a significant and independent association between UtA-PI and RFM (odds ratio (OR), 5.03 (95% CI, 4.21-6.01); P < 0.001), SGA (OR 2.41 (95% CI, 2.09-2.79); P < 0.001) and stillbirth (OR 1.55 (95% CI, 1.21-1.98); P< 0.001). The association between UtA-PI and SGA was significantly stronger in women presenting with RFM than in the rest of the cohort (P < 0.001). Similarly the association between UtA-PI and RFM was significantly stronger in those pregnancies complicated by stillbirth (P < 0.001). CONCLUSIONS Compared with normal pregnancies, those complicated by RFM, SGA and stillbirth at term had higher UtA-PI at 19-23 weeks' gestation. These findings support the assertion that RFM at term is independently related to placental dysfunction and subsequent risk for SGA and stillbirth.

Abstract
OBJECTIVES To evaluate the accuracy of gestation-adjusted birth-weight estimation using a three-dimensional (3D) fractional thigh volume (TVol) method in pregnant women with gestational diabetes mellitus (GDM), and to compare it with the conventional two-dimensional method of Hadlock et al. METHODS Pregnant women with GDM were referred at 34 to 36 + 6 weeks' gestation for ultrasound examination. Estimated fetal weight (EFW) was obtained using both the Hadlock and the TVol methods. Using a gestation-adjusted projection method, predicted birth weight was compared to actual birth weight at delivery. RESULTS Based on 125 pregnancies, the TVol method with gestation-adjusted projection had a mean (± SD) percentage error in estimating birth weight of -0.01 ± 5.0 (95% CI, -0.96 to 0.98)% while the method of Hadlock with gestation-adjusted projection had an error of 1.28 ± 9.1 (95% CI, -0.33 to 2.87)%. The mean percentage error of the two methods was significantly different (P = 0.039), while the random error was not (P = 1.0). For the prediction of macrosomia (birth weight ≥ 4000 g, n = 19), sensitivity was 84 and 63% for the TVol and Hadlock methods, respectively (95% CI for difference -2 to 44%, P = 0.22) and specificity was 96 and 89% for the TVol and Hadlock methods, respectively (95% CI for difference 5-9%, P = 0.01). CONCLUSIONS In women with GDM, a new method of estimating birth weight based on 3D-TVol measurements performed at 34 + 0 to 36 + 6 weeks' gestation and gestation-adjusted projection of estimated fetal weight, is more accurate than the standard method based on Hadlock's formula in predicting birth weight. The TVol method has comparable sensitivity but higher specificity than the Hadlock method in predicting neonatal macrosomia.

Abstract
OBJECTIVES To ascertain the outcome of twin reversed arterial perfusion (TRAP) sequence cases managed in our unit and to review systematically cases reported in the literature treated with intrafetal laser therapy. METHODS This was a retrospective cohort study of all TRAP sequence cases identified from 2000 to 2012 at our center. Pregnancy management and outcomes were ascertained from maternal and neonatal records. We also performed a meta-analysis of the literature on the use of intrafetal laser therapy for the treatment of TRAP. Adverse pregnancy outcome was defined as a composite of intrauterine death (IUD) and preterm birth before 37 weeks' gestation. RESULTS Twenty-three cases of TRAP were identified during the study period. Six were managed conservatively and 17 were treated with laser therapy. All cases managed conservatively were complicated by IUD at a median gestational age of 14 + 4 (interquartile range (IQR), 12 + 4 to 16 + 5) weeks. Among the treated cases, 14 (82%) delivered a healthy twin at a median gestational age of 37 + 1 (IQR, 34 + 0 to 38 + 3) weeks. Ten studies were reviewed in detail and the data were combined with those from the current study. The overall neonatal survival was 80%. Adverse pregnancy outcome was significantly lower when the treatment was performed before 16 weeks' gestation (19 vs 66%, P = 0.0025). CONCLUSION The study data demonstrate a high risk of spontaneous fetal demise in early pregnancy, lack of accurate prognostic markers and improved pregnancy outcome after laser therapy in cases of TRAP. In these cases we recommend elective treatment with intrafetal laser therapy at between 13 and 16 weeks' gestation.

Abstract
Background: The post-surgical management of ductal intraepithelial neoplasia (DIN) of the breast is still a dilemma. Ki-67 labelling index (LI) has been proposed as an independent predictive and prognostic factor in early breast cancer. Methods: The prognostic and predictive roles of Ki-67 LI were evaluated with a multivariable Cox regression model in a cohort of 1171 consecutive patients operated for DIN in a single institution from 1997 to 2007. Results: Radiotherapy (RT) was protective in subjects with DIN with Ki-67 LI ≥14%, whereas no evidence of benefit was seen for Ki-67 LI <14%, irrespective of nuclear grade and presence of necrosis. Notably, the higher the Ki-67 LI, the stronger the effect of RT (P-interaction <0.01). Hormonal therapy (HT) was effective in both Luminal A (adjusted hazard ratio (HR)=0.56 (95% CI, 0.33–0.97)) and Luminal B/Her2neg DIN (HR 0.51 (95% CI, 0.27–0.95)). Conclusion: Our data suggest that Ki-67 LI may be a useful prognostic and predictive adjunct in DIN patients. The Ki-67 LI of 14% could be a potential cutoff for better categorising this population of women at increased risk for breast cancer and in which adjuvant treatment (RT, HT) should be differently addressed, independent of histological grade and presence of necrosis.

Abstract
Abstract
BACKGROUND: metformin has been associated with antitumor activity in epidemiological and clinical studies. This effect has been related to different mechanisms of actions, including a reduction of the proliferative activity and an increase of apoptosis. We have recently shown that a 4 week pre-surgical treatment with metformin did not affect Ki-67 LI overall but reduced tumor proliferation Ki67 LI in breast cancer (BC) patients with insulin resistance (IR) (HOMA, fasting blood glucose (mmol/L)*insulin (mU/L)/22.5>2.8) or BMI>27 (Bonanni et al. JCO epub May 7, 2012). The objective of the current analysis was to determine whether metformin induced a modulation of apoptosis (TUNEL) overall and by HOMA index.
TRIAL DESIGN: After tumor biopsy we randomly allocated 200 non-diabetic women with operable breast cancer to either metformin (850 mg/bid) or placebo for 4 weeks prior to surgery. The primary outcome measure was the difference between arms in Ki-67 after 4 weeks of treatment. Here we analyzed the apoptotic cell nuclei in 88 consecutive core biopsies and their paired surgical samples from the initial 100 randomized subjects.
RESULTS: Median TUNEL levels at surgery (Metformin = 10%, IQR, 4–20, Placebo = 8%, IQR, 3–15) were significantly higher as compared with baseline (Metformin = 4%, IQR, 2–7, Placebo = 3%, IQR, 2–6, p < 0.0001), but no difference between arms was noted (p = 0.2, adjusted for age, BMI, TUNEL and Ki67 at baseline). Interestingly, Ki67 and TUNEL levels were highly and positively correlated both at baseline and at surgery (Spearman r=0.51, p < 0.0001). Furthermore, we found a trend to a different metformin effect by the HOMA index (p = 0.1). In the 59 women with HOMA <2.8 there was a higher level of TUNEL at surgery on metformin versus placebo (p = 0.05), while an opposite trend was found in the 28 women with HOMA>2.8 (p = 0.6).
CONCLUSIONS: The levels of TUNEL are significantly higher in the surgical specimens compared with baseline biopsy and are directly correlated with those of Ki-67 (TUNEL is high when Ki-67 is high). We found no significant modulation of TUNEL by metformin but a trend to a different effect according to the IR state, with a similar pattern to Ki-67: decrease by metformin in IR women and increase in non-IR women. Our findings confirm the notion that metformin has dual effects on breast cancer according to IR state. As expected, cancer apoptosis and proliferation are directly related. Our results strengthen the importance of placebo control arms in biomarker trials.

Abstract
INTRODUCTION Uterine artery (UtA) Pulsatility index assessed in the second trimester is known to be the best predictor of Pre-eclampsia (PE) in women with risk factors. The role of this index when PE occurs seems to be related with clinical outcome. OBJECTIVES To detect if there does exist a correlation between mean UtA PI, assessed at diagnosis of PE, and: (A) Gestational Age (GA) at delivery; (B) birth weight (BW) percentile. To detect the predictive value of mean UtA PI and the development of adverse pregnancy outcome (APO). METHODS Cohort study on 100 consecutive singleton pregnancies complicated with pre-eclampsia referred to our Department from January 2010 and December 2011. Doppler evaluations were performed from diagnosis to delivery. Mean UtA PI obtained at time of diagnosis of PE were analysed. PE was defined according to ISSHP criteria. Clinical and perinatal outcomes were reviewed. APO was defined as Apgar score less than 7 at five minutes, pH <7.20; birth weight <5th percentile (SGA), stillbirth or neonatal death. Receiver-operating characteristics (ROC) curve was used to determine the predictive ability for subsequent development of APO. RESULTS Maternal characteristics and main pregnancy outcomes are shown in Table 1. Fifty-six pregnancies developed APO. One case of stillbirth and four cases of neonatal death were observed. SGA occurred in 56/100 neonates; 52/95 (55%) live births were admitted to Neonatal Intensive Care Unit. Table 1. Mean UtA PI at diagnosis of PE was 1.40 (SD±0.28) in women that developed APO and 1.10 (SD±0.41) in women that did not develop APO (p=0.02). Pearson's Correlation coefficient for mean UtA PI and GA at Delivery was -0.533 (p=0.002); while for mean UtA PI and BW percentile was -0.466 (p=0.007). The prediction of subsequent development of APO, expressed as the area under ROC curve, was 61.6 (95% CI 0.44-0.79) for UtA PI at Diagnosis of PE. CONCLUSION Our data confirm that mean UtA PI, assessed at diagnosis of PE, represent a good independent predictor for GA at delivery end BW percentile. However the predictive value for development of APO seems to be poor.

Abstract
INTRODUCTION Pre-eclampsia (PE) is a leading cause of maternal and foetal mortality and morbidity. Chronic Hypertension (CH) and a previous PE are well known risk factors for PE. If the prevalence of PE in nulliparous is about 2%, it raise up to 7-10% in women with CH or a previous PE. However, the role of these risk factors when PE occurs is still under discussion OBJECTIVES To detect if maternal history of previous PE and/or Chronic Hypertension (CH) is associated with a worse clinical outcome in women affected by PE. METHODS Cohort study on 100 consecutive singleton pregnancies complicated by PE referred to our Department from January 2010 to December 2011. PE and CH were defined according to ISSHP criteria. Small for Gestational Age (SGA) was defined as Birth Weight under the 5th percentile per Gestational Age. Patients were divided into two groups depending on positive (Group A, n=25) or negative (Group B, n=75) history for PE and/or Chronic Hypertension (CH). Patients assessed to group A were under prophylactic therapy with ASA 100mg oid. Clinical and perinatal outcomes were reviewed. Adverse Pregnancy Outcome (APO) was defined as Apgar score less than seven at five minutes, pH<7.20; birth weight<5th percentile (SGA), stillbirth or neonatal death. RESULTS Groups were comparable for Maternal Age (Group A: 34years median, IQR 30-36yy; Group B: 34years, IQD 28-36yy ) and BMI (Group A: 23.7Kg/mq median, IQR 20.8-27.1Kg/mq; Group B: 22.4Kg/mq median IQR 20.3-26.0Kg/mq). One case of stillbirth (Group A) and four cases of neonatal death were observed, 1/25 in Group A (4%) and 3/75 (4%) in Group B. No differences were found in Gestational Age (GA) at diagnosis of PE (Group A: 32+2w median, IQR 28+0-35+4w; Group B: 33+2w median, IQR 30+0-36+1w); GA at delivery (Group A: 34+1w median, IQR 31+5-36+5w; Group B: 34+2w median, IQR 32+0-36+3w) Birth Weight percentile (Group A: 6th percentile median, IQR 2-21th percentile; Group B: 5th percentile median, IQR 1-15th percentile), prevalence of Small for Gestational Age (14/25 and 42/75, for Group A and B respectively), prevalence of APO (13/25 and 44/75, for Group A and B respectively). CONCLUSION Our data suggest that a positive history for PE and/or CH does not influence clinical outcome in women affected by PE. This result could be explained by the administration of prophylactic ASA 100mg oid in this group of patients.

Abstract
BACKGROUND Breast conserving surgery (BCS) plus external beam radiotherapy (EBRT) is considered the standard treatment for early breast cancer. We have investigated the possibility of irradiating the residual gland, using an innovative nuclear medicine approach named IART(®) (Intra-operative Avidination for Radionuclide Therapy). AIM The objective of this study was to determine the optimal dose of avidin with a fixed activity (3.7 GBq) of (90)Y-biotin, in order to provide a boost of 20 Gy, followed by EBRT to the whole breast (WB) at the reduced dose of 40 Gy. Local and systemic toxicity, patient's quality of life, including the cosmetic results after the combined treatment with IART(®) and EBRT, were assessed. METHODS After tumour excision, the surgeon injected native avidin diluted in 30 ml of saline solution into and around the tumour bed (see video). Patients received one of three avidin dose levels: 50 mg (10 pts), 100 mg (15 pts) and 150 mg (10 pts). Between 12 to 24 h after surgery, 3.7 GBq (90)Y-biotin spiked with 185 MBq (111)In-biotin was administered intravenously (i.v.). Whole body scans and SPECT images were performed up to 30 h post-injection for dosimetric purposes. WB-EBRT was administered four weeks after the IART(®) boost. Local toxicity and quality of life were evaluated. RESULTS Thirty-five patients were evaluated. No side effects were observed after avidin administration and (90)Y-biotin infusion. An avidin dose level of 100 mg resulted the most appropriate in order to deliver the required radiation dose (19.5 ± 4.0 Gy) to the surgical bed. At the end of IART(®), no local toxicity occurred and the overall cosmetic result was good. The tolerance to the reduced EBRT was also good. The highest grade of transient local toxicity was G3, which occurred in 3/32 pts following the completion of WB-EBRT. The combination of IART(®)+EBRT was well accepted by the patients, without any changes to their quality of life. CONCLUSIONS These preliminary results support the hypothesis that IART(®) may represent a valid approach to accelerated WB irradiation after BCS. We hope that this nuclear medicine technique will contribute to a better management of breast cancer patients.

Abstract
CONTEXT Development of gallstones (GS) is reported during the use of somatostatin analogs (SA) that are at present the mainstay for the medical treatment of acromegaly. OBJECTIVE To review the prevalence and clinical and biochemical correlates of GS in acromegalic patients. DESIGN AND SETTING Retrospective survey on hospital records in acromegalic patients followed up in the last 20 yr in tertiary referral centers. PATIENTS Four hundred and fifty-nine patients (272 females). MAIN OUTCOME MEASURES According to SA use and GS occurrence, patients were divided in 4 groups: 1) treated with SA without GS (SA+GS-), 2) GS developed while on SA (SA+GS+), 3) GS without SA use (SA-GS+), 4) neither GS nor SA (SA-GS-). RESULTS Patients were unevenly distributed in the 4 groups: 232, 125, 38, 64, respectively, pointing to a prevalence of GS in acromegaly of 8.3% at diagnosis with an additional 35% developing GS during SA. GS occurred after 3 months-18 yr (median 3 yr) of SA treatment, were diagnosed after symptoms in 17.6%, were associated to steatosis, ultrasound biliary dilation, and biochemical cholestasis, in 25.6%, 12.8%, and 4% of patients, respectively. Ursodehoxicolic acid was administered after GS occurrence, causing their dissolution in 39% of patients after 3-48 months (median 12). Cholecystectomy was performed in 16.8%of patients in group 2. At multivariate analysis obesity, dyslipidemia, and SA treatment were independent predictors of GS onset, whereas gender and age were not. CONCLUSIONS GS are a frequent occurrence in acromegalic patients treated with SA, may occur at any time, but are seldom symptomatic or prompt acute surgery. Obesity and dyslipidemia appear to play a major role in the occurrence of GS in acromegalic patients on SA treatment.

Abstract
BACKGROUND in acromegaly, the criteria for the cure of the disease after neurosurgery have become tighter and tighter. In contrast, the evaluation of control of disease activity during medical treatment is based upon the normalisation of IGF-I levels and epidemiological criteria, i.e. lessening GH (assessed by RIA) to levels reported to normalise increased mortality. The aim of this study was to evaluate GH and IGF-I suppression during prolonged SS analogues (SA) treatment. The concordance between "safe" GH and normalised IGF-I levels during SA was also assessed, according to gender and gonadal status. DESIGN multicentre, retrospective. Patients. GH/IGF-I levels were evaluated in 207 acromegalic patients (132 females, aged 20-85 yr) during a prolonged treatment (longer than 12 months) with individually tailored doses of depot SA( lanreotide or octreotide-LAR in 97 and 110 patients, respectively). Final IGF-I levels were transformed in z-scores using data collected in a large cohort of normal subjects of 3 different age groups (20-40 yr old, 41-60 yr old, 61-80 yr old, n=160, 148, 115, respectively), that allowed to set up quartiles of normality (I = 3rd-25th percentile, II = 26th-50th, III = 51th-75th, IV = 76th-97th). RESULTS fifty-nine and 19.3% of patients achieved GH levels <2.5 and <1 microg/l, respectively. IGF-I were normalised (z-score between 2 and -2) in 58.4% of patients. The distribution of normal IGF-I values among quartiles was uneven: 7%, 19%, 25%, and 49% of values were distributed in the I, II, III, and IV quartile, respectively. The concordance between GH and IGF-I values was poor: 28.4% of patients attaining GH values <2.5 microg/l had still pathological IGF-I (even 12.5% of those with GH <1 microg/l), and 39.3% of those with GH levels still above the "safe" limit had "nor IGF-I. Although proportions of IGF-I normalisation were not different between males and females, the regression line obtained between GH and IGF-I z-score showed the same slope but with a significantly lower intercept in regularly cycling women than in males and in postmenopausal females. Thus for any GH value, cycling females had lower IGF-I than menopausal women and males, and their IGF-I normalisation could be achieved by higher GH values. By ROC analysis, the achievement of normal IGF-I was predicted by the GH value of 1.8 microg/l in males and 2.4 microg/l in females. CONCLUSIONS in acromegalic patients on SA treatment, GH and IGF-I levels are often not concordant. In addition to age, sex is to be taken into account in the evaluation of hormonal targets. A better refinement of GH and IGF-I targets to be reached while on treatment with SA is warranted.

Abstract
Acromegaly is a severe slow-developing disease associated with a poor prognosis for cardiovascular disease. To evaluate the impact of age and gender on the severity of the disease, 151 de novo patients with acromegaly (79 women, 72 men, age range 19-77 yr) were included in this open retrospective multi-center cohort study. Basal GH and IGF-I levels, GH response after glucose load and maximal tumor diameter at MRI were measured in all patients at diagnosis. Fasting GH levels and maximal tumor diameter were similar in women and men, while serum IGF-I levels were lower (664.9+/-24.9 vs 755.9+/-32 microg/l; p=0.02) and GH nadir after glucose load was higher (27.5+/-3.7 vs 18.5+/-2.2 microg/l; p=0.04) in women than in men. In both sexes, patients' age was negatively correlated with basal and nadir GH, IGF-I levels and tumor size; fasting GH levels were positively correlated with IGF-I levels and nadir GH after glucose. No interaction between age and gender was found on biochemical and morphological parameters. At diagnosis, elderly patients with acromegaly have lower GH and IGF-I levels, lower GH nadir after glucose load and smaller adenomas than young patients. Women have lower IGF-I levels but higher GH nadir after glucose load than men. These age and gender differences should be considered to appropriately evaluate the activity of acromegaly throughout a life-span.

Abstract
The modulation of penicillin G acylase (PGA) properties via immobilization techniques has been performed studying the acylation of 7-aminocephalosporanic acid with R-mandelic acid methyl ester. PGA from Escherichia coli, immobilized onto agarose activated with glycidol (glyoxyl-agarose), has been used for the design of a novel one-pot synthesis of Cephamandole in aqueous medium and without isolation of intermediates, through three consecutive biotransformations catalyzed by D-amino acid oxidase, glutaryl acylase and PGA.

Abstract
A series of 2-substituted isothiazolo[5,4-b]pyridine-3(2H)-thiones, isothiazolo[5,4-b]pyridin-3(2H)-ones, N-substituted 2-sulfanylnicotinamides and the corresponding carbothioamide derivatives were synthesized and evaluated for their antimicrobial activity against several strains of Gram+ and Gram- bacteria and fungi. Chemical syntheses were resumed into a comprehensive cyclic route that enables the reversible conversion for each derivative of the series considered. Among the tested compounds the N-(aralkyl)-2-sulfanylnicotinamides show the highest fungitoxicity (MIC = 1.25-5 microg/ml). The best activity towards Gram-positive bacteria was in the range of 2.5-5 microg/ml. Activity against Gram-negative bacteria was generally very poor for all compounds.

Abstract
OBJECTIVE Slow-release (SR) lanreotide is a long-acting somatostatin analog that has been developed in order to overcome the inconvenience of multiple daily subcutaneous injections of octreotide, required for metabolic control in acromegaly. Lanreotide SR has been found to be well tolerated and effective in reducing GH and IGF-I levels but clinical data are still limited compared with those with subcutaneous octreotide treatment. DESIGN Sixty-six unselected patients with active acromegaly were therefore evaluated in a multi-center, prospective, open label study. Lanreotide SR was given at a dose of 30mg intramuscular every 7-14 days. METHODS At baseline and after 2, 4, 8, 12, 24, 36 and 48 weeks patients underwent a clinical examination with assessment of acromegaly related symptoms, and blood was sampled for serum GH, IGF-I, prolactin, glycosylated hemoglobin, fasting glucose, hematology, kidney function and liver function tests. Biliary ultrasonography and pituitary magnetic resonance imaging were performed at baseline and after one year. RESULTS Treatment resulted in a significant improvement in the symptom score from 2.69+/-0.27 to 1.06+/-0.17 (P<0.0001). Serum IGF-I levels fell from 699+/-38microg/l at baseline to 399+/-26microg/l (P<0.0001, n=60) after one month, after which levels remained stable: 480+/-37microg/l after 6 months (n=54) and 363+/-32microg/l after one year (n=46). GH levels dropped from 13.8+/-3.2microg/l to 4.3+/-0.7microg/l after one month (P<0.0001, n=60) and remained stable thereafter: 3.9+/-0.4microg/l (n=54) after 6 months and 3.5+/-1.1microg/l after one year (n=46). Twenty-nine out of 66 patients (44%) attained a normal age-corrected IGF-I level and 30 patients (45%) attained a GH level below 2.5microg/l. Pituitary adenoma shrinkage of at least 25% was found in 5 of 14 patients (36%) after one year. Side effects were mainly transient gastrointestinal symptoms and pain at the injection site, resulting in drug discontinuation in only 6 patients (9%). Two patients developed new gall stones. No difference was found between subcutaneous octreotide and lanreotide SR in efficacy and almost all patients preferred the easier dose administration of lanreotide SR. CONCLUSIONS Long-term treatment of acromegaly with SR-lanreotide is effective in controlling GH and IGF-I levels and symptoms and is well tolerated in the majority of patients. Compared with subcutaneous octreotide, lanreotide SR considerably improves patient's acceptance of therapy while having the same overall efficacy.

Abstract
BACKGROUND AND PURPOSE Intravascular treatment of intracranial aneurysms is a relatively new therapeutic technique and long-term controlled angiographic trials are needed to assess persistence of aneurysm occlusion. Our purpose was to evaluate the effectiveness of 3D time-of-flight (3D-TOF) MR angiography as a noninvasive screening tool in the follow-up of cerebral aneurysms treated with Guglielmi detachable coils (GDCs). METHODS Forty-nine patients with 50 intracranial aneurysms previously treated with GDCs were studied with both DSA and 3D-TOF MR angiography. In 14 cases, a second follow-up examination was performed, for a total of 64 aneurysms evaluated. In 25 aneurysms, both pre- and postcontrast MR angiographic studies were obtained. RESULTS In seven of 64 aneurysms, the MR angiographic studies were considered to be unreliable owing to the presence of artifacts that obscured part of the parent artery and did not allow an accurate evaluation of the aneurysm neck. These seven aneurysms, however, all were shown to be completely occluded at digital subtraction angiography (DSA). In the remaining 57 aneurysms, DSA revealed complete occlusion in 39 and the presence of residual patency in 18, whereas MR angiography showed complete occlusion in 38 and residual patency in 19. Enhanced MR angiography proved to be useful in evaluating residual patency in large and giant aneurysms and in better depicting the distal branch arteries. CONCLUSION Although artifacts related to the presence of coils are evident on a considerable number of imaging studies, our findings indicate that MR angiography is useful in the evaluation of residual patency of cerebral aneurysms treated with GDCs and may eventually prove valuable in the follow-up of those cases in which a good initial correlation with DSA was demonstrated.

Abstract
Disseminated infections with Mycobacterium tuberculosis (MT) and Mycobacterium avium complex (MAC) are increasingly opportunistic diseases in patients with advanced acquired human immunodeficiency syndrome (AIDS). A series of N-alkyl-1, 2-dihydro-2-thioxo-3-pyridinecarbothioamides has been synthesized, and MICs for MT and MAC strains, either standard or isolated from infected patients, have been determined. Preliminary tests show a good activity and a very low toxicity for some derivatives. Pharmacokinetic studies in the rat show a very rapid elimination from the body after intravenous administration and a poor absorption after oral administration.

Abstract
Penta-O-acetyl-alpha-D-glucopyranose was selectively deacetylated in aqueous media by lipases from Candida cilindracea (CCL) adsorbed on octyl-agarose support. Enzymatic hydrolyses was regioselective at the 4-position under neutral pH and towards the 6 position under acidic conditions. This enzymatic approach allows the one step synthesis of 1,2,3,6-tetra-O-acetyl-alpha-D-glucopyranoses 1, a useful intermediate in oligosaccharide synthesis.

Abstract
BACKGROUND To review a series of 11 patients affected by hyperplasia of parathyroid glands and to discuss diagnostic and therapeutic tools. METHODS A series of 11 patients out of 44 (= 25%) with primary hyperparathyroidism has been retrospectively reviewed. They underwent surgery in I surgical Department of OORR of Bergamo. All 11 patients were submitted to ultrasound and computed tomography examination before surgery, without any localisation of hyperplastic or adenomatous tissue. An exploring cervicotomy was performed with subtotal parathyroidectomy after the anatomopathological result of hyperplasia. RESULTS No adverse effects related to surgery were observed. All patients could be considered as cured with a median follow-up of 36 months. CONCLUSIONS Among hyperparathyroidism, hyperplasia is an underhand form and even if the laboratory diagnosis is simple, the imaging techniques cannot always localise the pathologic tissue. Personal experience shows the role of subtotal parathyroidectomy (removal of 3 parathyroid glands and a half of the last one) confirmed by the absence of adverse effects or relapse with a median follow-up of 36 months.

Abstract
It is essential to know whether drinking water contains any pesticides up to concentrations close to the European Union limit of 0.1 microgram/l, in order to protect the population. Mass spectrometry (MS) using a suitable internal standard (I.S.) should improve the quantitative analysis of pesticides, the I.S. circumventing loss of compounds during the analytical procedure and correcting the analytical variability. In this study we verified this assumption in GC-MS, synthesising specific internal standards for four organophosphorus pesticides with poor stability, comparing the performances with and without the I.S.

Abstract
The FRAXE fragile site, 600 Kb distal to the more common FRAXA, has been reported to be expressed in subjects with mild nonsyndromal mental retardation. Amplification of more than 200 GCC repeats associated with methylation of the adjacent CpG island at Xq28 is responsible for FRAXE fragility. We describe two unrelated, mentally retarded males identified during a screening for fragile X syndrome. Both index cases underwent FRAXE molecular analysis, following cytogenetic expression of the fra X site and negative FRAXA test. In family 1, we were able to investigate other 13 subjects over three generations, identifying two additional FRAXE-positive males, one with a fully mutated allele and one with a mosaic genotype. Detailed evaluation of physical traits and psychometric tests was performed on three retarded males from family 1 and the propositus from family 2. All of them were found to lack a definite phenotype, and showed different degrees of mental retardation. Slight mental retardation was evident in the mosaic male, suggesting that methylation might be an important determinant of mental impairment.

Abstract
A transient rise in serum alkaline phosphatase (ALP) activity (ALP flare) after androgen deprivation in prostate cancer patients with bone metastases has been previously correlated with both response to therapy and poor prognosis. In the present study we analyzed data coming from an Italian multicenter phase III, trial aimed to compare the efficacy of treatment with goserelin alone with that of goserelin plus mitomycin C. Sixty-seven bone metastatic patients were enrolled: 32 were treated with goserelin and 35 with and goserelin plus mitomycin. 58 cases had ALP measured every month; and were considered for flare assessment. Remarkably elevated ALP and PSA levels at baseline were significantly correlated with poor prognosis. The addition of mitomycin to goserelin resulted in a greater percent reduction of PSA values with respect to goserelin alone but did not augment the time to progression and overall survival. The monthly profile of ALP serum levels was superimposable in patients assigned to hormone therapy or chemotherapy plus hormone therapy. Patients showing a flare in ALP activity (transient rise > 15% in ALP values with respect to baseline at the first month) were classified as responders to therapy or as having stable disease upon PSA evaluation and/or at bone pain assessment, but had a shorter time to progression (median 12 months) in comparison to those showing a different ALP pattern (median 23 months). The measurement of flare in ALP activity during androgen suppression with or without concomitant mitomycin administration, may permit the early identification of patients who are likely to progress rapidly, and hence be candidate for more aggressive treatments.

Abstract
N-Hydroxyethyl- and N-hydroxypropyl-1,2-benzisothiazol-3(2H)-one carbamic esters were prepared in order to test their activity against representative bacterial and fungal strains. The obtained results were compared with those reported for parent alcohols and some interesting considerations were drawn. None of the studied derivatives possess genotoxic activity in the Bacillus subtilis rec-assay and Salmonella-microsome test.

Abstract
OBJECTIVE In the medical treatment of acromegaly different factors are influential; among these the impact on growth hormone binding protein (GHBP) has not been clarified. DESIGN Twenty acromegalic patients and nineteen age- and gender-matched normal subjects participated in this study. The patients were treated for 21 months with depot long-acting microsphere-enclosed octreotide (Sandostatin-LAR). Previously, all the patients were treated s.c. with octreotide t.i.d. After a 2-week wash-out period (baseline) the patients received the first i.m. injection of the long-acting octreotide. The first two injections were administered at 60-day intervals; thereafter the injections were at 28-day intervals. METHODS The levels of GHBP, complexed GHBP, growth hormone (GH) and insulin-like growth factor-I (IGF-I) were determined in fasting serum samples. RESULTS In the 2-week wash-out period GHBP levels decreased from 1.13 +/- 0.17 to 0.92 +/- 0.15 nmol/l (P < 0.05). During the 21-months treatment, GHBP increased again to 1.10 +/- 0.16 nmol/l. In the age- and gender-matched control group GHBP levels were significantly higher at all times (1.95 +/- 0.21 nmol/l. P(all) < 0.02). Mean levels of 8-h GH decreased from 12.6 +/- 2.58 microg/l at baseline to 1.97 +/- 0.20 microg/l after 21 months of treatment (P < 0.05). Mean 8-h GH levels were unchanged during long-acting octreotide treatment compared with levels during s.c. treatment (1.97 +/- 0.20 microg/l and 1.90 +/- 0.20 microg/l respectively). In fasting blood samples GH-complexed GHBP ranged from 13.8 +/- 2.4% (9 months) to 25.4 +/- 4.5% (baseline) of total GHBP. Serum IGF-I increased from 367 +/- 45 to 764 +/- 80 microg/l (P < 0.05) during the 2-week wash-out period and decreased to 290 +/- 35 microg/l (P < 0.05) after 21 months of treatment with long-acting octreotide. IGF-I levels after 21 months were significantly lower than during s.c. octreotide treatment (P < 0.05). CONCLUSION Serum GHBP levels are similar during treatment with long-acting octreotide as compared with regular octreotide. Furthermore, significant changes in GHBP can occur within 2 weeks. Finally, in addition to the lowering effect on GH levels, the induced increase in GHBP levels may imply a further advantage in octreotide treatment of acromegaly. circulating GH bound to GHBP may less readily reach the tissues.

Abstract
A series of N-(2-hydroxyethyl)-1,2-benzisothiazol-3(2H)-one and -thione carbamic esters have been synthesised and tested against Mycobacterium avium strains. The MIC values determined by the radiometric broth dilution method were between 2 and 8 micrograms/mliters for the benzisothiazolthione derivatives and between 16 and 32 micrograms/mliters or higher for the corresponding benzisothiazolone derivatives.

Abstract
A stable and sustained suppression of growth hormone (GH) secretion was noted in 101 patients treated long term with individual doses (20 and 30 mg in 89 patients, 40 mg in 12 patients) of Sandostatin LAR (Sandoz Pharma Ltd, Basel, Switzerland). Doses of 20 mg and 30 mg at 4-week intervals delivered average octreotide concentrations of 1,348 +/- 483 ng/L and 2,631 +/- 1,026 ng/L, respectively, in steady-state conditions and provided adequate control of patients who had been well controlled during treatment with 0.1 mg and 0.2 mg thrice-daily subcutaneous (SC) Sandostatin. Suppression of GH serum concentrations to less than 5 micrograms, 2 micrograms, and even 1 microgram/L was recorded in more patients and more consistently during long-term treatment with Sandostatin LAR than Sandostatin. A marked decrease or even a normalization of insulin-like growth factor-1 (IGF-1) serum concentrations was observed after the first double-blind 10-, 20-, or 30-mg dose of Sandostatin LAR. A progressive improvement was recorded during long-term treatment, with normalization of IGF-1 serum concentrations in 65.3% of patients. A marked clinical improvement was observed in parallel, with 36 of 101 patients (35.6%) becoming asymptomatic after the nineteenth injection of Sandostatin LAR. A greater than 20% shrinkage of the GH-secreting adenoma was also recorded in 12 of 14 patients treated with Sandostatin LAR after receiving only 2 to 4 weeks of treatment with SC Sandostatin and in 11 of 18 patients receiving Sandostatin LAR as adjuvant therapy after failure of surgery. The systemic tolerability of Sandostatin LAR was good, and most adverse events were mild and short term (1 to 2 days). No impairment of thyroid function was detected. Newly occurring gallstones were recorded in four of 101 patients and microlithiasis in four of 101 after up to 30 months of treatment with Sandostatin LAR. Due to its excellent efficacy, good tolerability, convenience of administration, and acceptability by patients, Sandostatin LAR is considered a promising therapeutic tool in the management of acromegalic patients.
