Abstract
Introduction Virtual coaches (VCs) can support people with Diabetes Mellitus (DM) by motivating them to better manage their health. Few VCs were aimed at providing psychosocial support. In this regard, motivation is a pivotal construct in diabetes self-management as it allows adults with DM to adhere to the clinical recommendations. Objectives The present study aimed to develop a VC able to motivate adults with DM to adopt and acquire healthier coping strategies, to decrease symptoms of depression, anxiety, perceived stress, and diabetes-related emotional distress, while also improving their well-being. Methods A total of 12 adults with DM (M=27.91 years; SD=9.82) interacted with a VC, called Motibot using Telegram for an overall duration of 12 sessions. Participants completed a battery of instruments at pre-, post-intervention and follow-up. Results highlighted a decrease in anxiety, and depression symptoms between pre-, post-intervention and follow-up, as also showed by the results that emerged through the text mining. Motibot was perceived as motivating and encouraging in the adoption of appropriate coping strategies, such as mindfulness practices. Motibot was also perceived as trustworthy, reflective, and stimulating in its dialogical interaction. Indeed, adults felt involved in the interaction with Motibot, thereby showing an overall perception of a better quality of life, in the absence of diabetes distress. Conclusions This study sheds light on the importance of VCs in health care for people with DM for psychosocial support. This is the first experimental study on the matter, and thus, further iterations of the intervention are needed using a larger sample size. Disclosure No significant relationships.

Abstract
The detection of atypical Kinetoplastida in vertebrate hosts and vectors might suggest unexpected host-parasite contacts. Aside to major vectors of Leishmania (Leishmania) infantum in Italy (e.g. Phlebotomus perniciosus and Phlebotomus perfiliewi), the sand fly fauna also includes Sergentomyia minuta, herpetophilic and proven vector of Leishmania (Sauroleishmania) tarentolae, in which records of blood meal on mammals and detection of L. infantum DNA are increasing. This study was conducted in Central Italy aiming to molecularly detect potential atypical Leishmania host-vector contacts. Detection of Leishmania spp. DNA was performed by polymerase chain reaction (SSU rRNA, ITS1 targets) on field-collected sand fly females (N = 344), blood samples from humans (N = 185) and dogs (N = 125). Blood meal identification was also performed on engorged sand flies. Leishmania spp. DNA was found in 13.1% sand flies, 3.7% humans and 14.4% dogs. Sequence analysis identified L. infantum in S. minuta (4.4%), P. perniciosus (9.1%), humans (2.2%) and dogs (14.4%). Leishmania tarentolae was detected in S. minuta (12.6%), P. perfiliewi (6.6%) and human (1.6%) samples. Of 28 S. minuta examined for blood meal, 3.6 and 21.4% scored positive for human and lizard DNA, respectively. These results indicate the importance of one-health approach to explore new potential routes of transmission of leishmaniasis involving S. minuta.

Abstract
Abstract
Backgrounds
Intestinal parasitic infections (IPI) are a major health issue for children of low- and middle-income countries. Water, sanitation and hygiene (WASH) practices are crucial for preventing IPI. The aim of the study was to evaluate the effects of a school-based health education intervention on handwashing behavior and IPI prevalence in children
Methods
This is a randomized intervention trial in 8 primary schools in rural communities over the course of 3 school years; preliminary results from the first two years of the trial are here presented. Schools were randomly selected and assigned in a 1:1 ratio to intervention or control (no intervention) groups. For each school year, the intervention included 14 school-based educational sessions and 2 skit events, involving children aged 8-12 years. Knowledge, attitude and practice questionnaire and handwashing at key events was assessed at the beginning and end of each school year. IPI prevalence was assessed with repeated cross-sectional parasitology surveys 12 months apart, involving a minimum of 50 children for each school
Results
At baseline, no significant differences between intervention and control schools were present in the proportion of children who washed their hands at key events (7.2% vs 9.3%, p = 0.28), in IPI (79.4% vs 75.3%, p = 0.3) and multiple parasitic infections (MPI) prevalences (47.6 vs. 38.6; p = 0.051). At the end of the second year, the percentage of children who washed their hands at key events was significantly higher in the intervention schools (75.4% vs 12.1%, p < 0.001), and the prevalence of IPI and MPI in the intervention schools were respectively about 25% and 15% lower than in the control schools (respectively, 42.9% vs 67.8%, p < 0.001; 16.1% vs 31.6%, p < 0.001)
Conclusions
A school-based health education intervention could achieve significant changes in hand-washing behaviors and reduction in the prevalence of IPI in children. The third year survey results are needed to confirm these findings
Key messages
An health education intervention on water, sanitation and hygiene (WASH) practices can reduce the risk of IPI infection in children. An health education intervention on water, sanitation and hygiene (WASH) practices could be configured as a sustainable long-term approach to intestinal parasitic infections control in children.

Abstract
We describe a rare case of Dirofilaria repens infection presenting as peripheral lung nodules and mimicking a metastatic focus from a previously diagnosed cutaneous melanoma. To avoid invasive investigations before arriving at the correct diagnosis, dirofilariasis should be included as a part of the diagnostic process in subjects with lung nodules who live in (or have traveled to) endemic regions.

Abstract
Essentials Three dominant variants for the autosomal recessive bleeding disorder type-8 have been described. To date, there has been no phenotype/genotype correlation explaining their dominant transmission. Proline plays an important role in P2Y12R ligand binding and signaling defects. P2Y12R homodimer formation is critical for the receptor function and signaling. SUMMARY Background Although inherited platelet disorders are still underdiagnosed worldwide, advances in molecular techniques are improving disease diagnosis and patient management. Objective To identify and characterize the mechanism underlying the bleeding phenotype in a Caucasian family with an autosomal dominant P2RY12 variant. Methods Full blood counts, platelet aggregometry, flow cytometry and western blotting were performed before next-generation sequencing (NGS). Detailed molecular analysis of the identified variant of the P2Y12 receptor (P2Y12R) was subsequently performed in mammalian cells overexpressing receptor constructs. Results All three referred individuals had markedly impaired ADP-induced platelet aggregation with primary wave only, despite normal total and surface P2Y12R expression. By NGS, a single P2RY12:c.G794C substitution (p.R265P) was identified in all affected individuals, and this was confirmed by Sanger sequencing. Mammalian cell experiments with the R265P-P2Y12R variant showed normal receptor surface expression versus wild-type (WT) P2Y12R. Agonist-stimulated R265P-P2Y12R function (both signaling and surface receptor loss) was reduced versus WT P2Y12R. Critically, R265P-P2Y12R acted in a dominant negative manner, with agonist-stimulated WT P2Y12R activity being reduced by variant coexpression, suggesting dramatic loss of WT homodimers. Importantly, platelet P2RY12 cDNA cloning and sequencing in two affected individuals also revealed three-fold mutant mRNA overexpression, decreasing even further the likelihood of WT homodimer formation. R265 located within extracellular loop 3 (EL3) is one of four residues that are important for receptor functional integrity, maintaining the binding pocket conformation and allowing rotation following ligand binding. Conclusion This novel dominant negative variant confirms the important role of R265 in EL3 in the functional integrity of P2Y12R, and suggests that pathologic heterodimer formation may underlie this family bleeding phenotype.

Abstract
INTRODUCTION Mean platelet volume (MPV) assists the differential diagnosis of inherited thrombocytopenia (IT) but lacks standardisation and varies between automated analysers. Classification of IT based on mean platelet diameter (MPD) has been proposed by an international collaborative study but has not been validated. METHODS To assess the applicability of MPD to classify forms of IT, digital images of blood films from patients with established genetic causes for IT were generated, and the MPD measured (ZEISS Axio-scanner and Image J software) by a blinded reviewer. Comparison was made to the proposed classification system. RESULTS Mean platelet volume was measured in thrombocytopenia with different genetic aetiologies, bilallelic BSS (bBSS) (n = 1), monoallelic BSS (mBSS) (n = 2), MYH9-related disorders (MYH9-RD) (n = 11), GFI1B-related thrombocytopenia (RT) (n = 15), FLI1-RT (n = 2), TUBB1-RT (n = 3), ITGA2B/ITGB3-RT (n = 1), RUNX1-RT (n = 2) and controls (n = 54). bBSS and 82% of MYH9-RD samples had MPD >4 μm which correlated with "IT with giant platelets." Only 55% of samples expected in the "large platelet group" had MPD meeting the classification cut-off (MPD >3.2 μm). FLI1-RT MPD were significantly larger than expected whilst ITGA2B/ITGB3-RT MPD were smaller than proposed. MPD in FPD/AML were "normal." CONCLUSION Platelet MPD measurements are a useful guide to classify IT, but the time taken to record measurements may limit clinical applicability.

Abstract
Essentials The phenotypes of different growth factor-independent 1B (GFI1B) variants are not established. GFI1B variants produce heterogeneous clinical phenotypes dependent on the site of mutation. Mutation of the first non-DNA-binding zinc-finger causes a mild platelet and clinical phenotype. GFI1B regulates the CD34 promoter; platelet CD34 expression is an indicator of GFI1B mutation. SUMMARY Background Mutation of the growth factor-independent 1B (GFI1B) fifth DNA-binding zinc-finger domain causes macrothrombocytopenia and α-granule deficiency leading to clinical bleeding. The phenotypes associated with GFI1B variants disrupting non-DNA-binding zinc-fingers remain uncharacterized. Objectives To determine the functional and phenotypic consequences of GFI1B variants disrupting non-DNA-binding zinc-finger domains. Methods The GFI1B C168F variant and a novel GFI1B c.2520 + 1_2520 + 8delGTGGGCAC splice variant were identified in four unrelated families. Phenotypic features, DNA-binding properties and transcriptional effects were determined and compared with those in individuals with a GFI1B H294 fs mutation of the fifth DNA-binding zinc-finger. Patient-specific induced pluripotent stem cell (iPSC)-derived megakaryocytes were generated to facilitate disease modeling. Results The DNA-binding GFI1B variant C168F, which is predicted to disrupt the first non-DNA-binding zinc-finger domain, is associated with macrothrombocytopenia without α-granule deficiency or bleeding symptoms. A GFI1B splice variant, c.2520 + 1_2520 + 8delGTGGGCAC, which generates a short GFI1B isoform that lacks non-DNA-binding zinc-fingers 1 and 2, is associated with increased platelet CD34 expression only, without quantitative or morphologic platelet abnormalities. GFI1B represses the CD34 promoter, and this repression is attenuated by different GFI1B zinc-finger mutations, suggesting that deregulation of CD34 expression occurs at a direct transcriptional level. Patient-specific iPSC-derived megakaryocytes phenocopy these observations. Conclusions Disruption of GFI1B non-DNA-binding zinc-finger 1 is associated with mild to moderate thrombocytopenia without α-granule deficiency or bleeding symptomatology, indicating that the site of GFI1B mutation has important phenotypic implications. Platelet CD34 expression appears to be a common feature of perturbed GFI1B function, and may have diagnostic utility.

AIM The aim of this paper was to evaluate the lower uterine segment (LUS) thickness through transvaginal sonography in late preterm and full term pregnancies with a single previous Cesarean section, to correlate the obtained LUS measurements with intraoperative observations, and to identify a predictive cut-off value in order to select the best candidates for a vaginal birth after Cesarean delivery (VBAC). METHODS Two hundred and fourteen women with a single previous Cesarean section who had an ultrasound measurement of the LUS thickness (stratified in S1, S2 and S3) in pregnancy were enrolled. The outcome of interest was the visual finding of a thin uterine scar at the time of the iterative Cesarean section. Linear regression was used to correlate the LUS thickness with gestational age (GA). A ROC curve has been used to determine the detection rate (DR) and the risk of each actual value of LUS thickness versus a thin uterine scar (outcome of interest). RESULTS The LUS thickness was correlated with the gestational age (R2=0.034, P-value =0.005). The DR as estimated by ROC curves to detect a translucent lower uterine segment (S3) was 94.1% at a false positive rate (FPR) of 20%. The correspondent cut-off value was 1.8 mm. Finally a likelihood ratio (LR) of observing S3 was estimated. At the quoted cut-off of 1.8 mm the LR was 3. As demonstrated, for a segment of 1 mm the LR was instead about 13. CONCLUSION The obtained values lead us to the conclusion that a thickness less than 1.8 mm can be reasonably considered a valid cut-off value to identify patients with a higher risk of thin uterine scar.

Abstract
Few studies have been published on bovine piroplasmoses in Italy, and therefore a clear picture of the epidemiology of these infections is difficult to obtain. Vertebrate and invertebrate hosts in Central and Northern Regions of Italy were investigated in 2005 and 2006, when microscopy, molecular tools and serological tests were applied to 468 blood samples drawn from cattle in order to evaluate the presence of these protozoa and identify possible risk factors. Ticks were also collected, identified and analyzed by molecular techniques. Microscopy identified 6.5% of the animals as positive, whereas PCR detected piroplasm DNA in 21.6%. BLAST analysis showed 67 amplicons (17.0%) referable to the Theileria sergenti/buffeli/orientalis group, 17 (4.3%) to Theileria annae, and 1 to Babesia divergens. Serology evidenced a prevalence of 45.4% for Babesia bovis, 17.4% for Babesia bigemina, and 34.9% for B. divergens. The 127 collected ticks were identified as belonging to 5 species, mostly represented by Rhipicephalus bursa, Hyalomma marginatum and Ixodes ricinus. Molecular analyses evidenced the presence of B. bovis and B. bigemina, in 3 and 5 ticks, respectively. Our findings suggest that different species of piroplasms are circulating in bovine populations in Central and Northern Italy, and provide new insights into the complex epidemiology of bovine piroplasmoses in Italy.

Abstract
Human dirofilariosis is a relatively rare infection caused by filarial worms of the genus Dirofilaria. We herein report the first case of human subcutaneous dirofilariosis in the southeastern part of Serbia. A complete alive nematode was removed from a nodule in the periorbital region of a 50-year-old woman. The nematode was morphologically identified as a D. repens-like immature female. The diagnosis was confirmed with molecular methods. The patient was probably infected in the South-East Serbia as she had not travelled abroad, nor in other parts of Serbia such as Vojvodina, recently identified as a hyperendemic area for D. repens infection of dogs.

Abstract
OBJECTIVE To investigate the clinical implications of two categories of fetal bilateral cleft lip and palate (BCLP): with premaxillary protrusion and with a flattened profile. METHODS This was a retrospective study of fetuses with a prenatal diagnosis of BCLP at the Department of Obstetrics and Gynecology of the University of Bologna in the period 1991-2005. RESULTS BCLP was diagnosed prenatally in 14 cases (mean gestational age at diagnosis, 21 (range, 12-36) weeks). In nine of these, there was a premaxillary pseudomass; in the remaining five, the profile was flat. Associated structural and/or chromosomal anomalies were found in two of the nine with a premaxillary pseudomass and in all five of those with a flat profile (P = 0.02). All fetuses with a flat profile had aneuploidies (three trisomy 18, one trisomy 13, one trisomy 8 mosaic), as did one of the nine with a premaxillary pseudomass. Eight of the pregnancies were terminated, including three of those with a premaxillary pseudomass and all five of those without. All continuing pregnancies resulted in live births, although one neonate affected by Krabbe's disease died shortly after birth. CONCLUSIONS Our findings suggest that a third of cases of BCLP diagnosed in utero have a flat profile and these are at high risk of lethal aneuploidies.

Abstract
In Italy, canine piroplasmosis is believed to be widespread, but few data are available on its presence in most areas. In 2005 and 2006, vertebrate and invertebrate hosts were investigated in Central and Northern Regions of the Country. Microscopy on blood smears, molecular tools and serological tests were applied to 420 blood samples collected from dogs, in order to evaluate the presence of these protozoa and to identify possible risk factors. Moreover, ticks were analyzed by molecular techniques. Microscopy identified as positive 2.8% of the animals, all from Central Italy, and PCR detected 'piroplasm' DNA in 6.0%. Serology evidenced a mean prevalence of 34.0% with a decreasing trend from Central to Northern areas. The 507 collected ticks were identified as belonging to 8 species, mostly represented by Rhipicephalus sanguineus (n=376) and Ixodes ricinus (n=58). Molecular analyses evidenced the presence of babesial parasites (Babesia canis canis, B. canis vogeli, B. microti-like) in 25 (4.9%) of them; in Rh. sanguineus there was also demonstration of the vertical transmission of B. canis canis. Statistical analysis identified 'kennel' as risk factor for Babesia infection. Our findings evidenced that different species of piroplasms potentially infectious for dogs are circulating in Italy, and that epidemiological aspects of these infections are more complex than expected. Vector importance of both Rh. sanguineus and I. ricinus is hypothesized, but further investigation is needed.

Abstract
During a survey carried out to define the occurrence of Echinococcus granulosus in cattle bred in the province of Rieti (Central Italy), molecular diagnostics (PCR amplification and sequencing of a partial region of the mitochondrial CO1 gene) showed that 6/10 positive bovines harboured hydatid cysts (No.=16) genetically identical (95.8-100%) to the Indian buffalo genotype G3. As far the location of the 16 cysts, 11 of them were found in the lungs of three animals, whereas 5 cysts were in the liver of three parasitized hosts. The occurrence of genotype G3 in 60% of parasitized bovines living in an area never studied before provides more definite evidence about the existence of the strain in this region, and proves that cattle have to be considered a non-accidental host.

Abstract
To identify the natural vectors of Dirofilaria repens Railliet et Henry, entomological samplings were carried out in four sites within the Lazio region, foci of canine subcutaneous dirofilariasis. Collections were made in 2002-2003 by means of dog-baited and miniature Centers for Disease Control and Prevention traps as well as on humans. Microscopy identified 1576 attracted mosquito females as belonging to six species, but molecular diagnostics detected filarial DNA only in Culex pipiens L. and Aedes albopictus (Skuse, 1894). Dirofilaria immitis Leidy DNA, D. repens DNA, or both were found in the head and thorax of both mosquitoes. The simultaneous presence of vectors showing diurnal and nocturnal activity patterns is of concern for animal and human health. The finding of D. immitis DNA in mosquitoes in areas where only D. repens was been recovered in dogs also demonstrates that this filarial parasite circulates among carnivores (wild or domesticated pets).

Abstract
OBJECTIVES To calculate the risk of developing pre-eclampsia (PET) in a consecutive series of low-risk women at 18-24 weeks' gestation, using recently published logistic regression models. METHODS This was a prospective study, with complete follow-up, in a consecutive series of unselected low-risk singleton pregnancies. Uterine artery pulsatility index as well as a combination of maternal factors were recorded at 18-24 weeks' gestation. The distribution of the estimated risks for the 16 PET patients was compared with that obtained for 136 women who had a normal pregnancy, as assessed by routine testing. A receiver-operating characteristics (ROC) curve was plotted to evaluate the detection rate at fixed false-positive rates (FPRs) of 5%, 10% and 20% and the corresponding odds cut-offs. RESULTS Just 1/16 (6.2%) women with PET developed the disease before the 34(th) week of gestation. Using the 'All PET' logistic regression model, for 16 PET cases the overall median odds was 1 : 1454, higher compared with that of 1 : 41635 estimated for controls. Using the 'PET >or= 34 weeks' model, the median odds of the 15 women who developed PET late was 1 : 3405, compared with 1 : 40785 for controls. In the case of PET before 34 weeks, the risk was 1 : 426373 vs. 1 : 4159823126 estimated for controls ('PET < 34 weeks' model). Detection rates for the All PET model were 18%, 50% and 62% at a FPR of 5%, 10% and 20%, respectively. For the PET >or= 34 weeks model these detection rates were 6%, 46% and 60%, respectively. CONCLUSION Even though the individual odds estimation is too low to represent the real risk of PET, the recently published logistic regression models detected more than 60% of PET at a FPR of 20% for both All PET and PET >or= 34 weeks models. Using these models in clinical practice does not seem to give any significant improvement over Doppler alone in the prediction of PET, but the use of a PET-specific odds instead of an actual Doppler value alone seems to be useful for clinical management.

Abstract
Entomological investigations by means of dog- and human-baited traps were carried out in summers 2000-2002 in urban and rural areas of the Tuscan region in central Italy. The aim of the study was to define the mosquito species involved in the transmission of Dirofilaria nematodes and to assess the risk that their presence might represent for animal and human health. Nocturnal fieldwork on host-seeking activity and feeding preferences was followed by microscopic identification of the mosquito species attracted and by molecular identification of Dirofilaria parasites in mosquitoes. In total, 3,611 mosquito females belonging to 12 species, largely represented by Culex pipiens L. and Aedes caspius (Pallas), were caught. Some females of each species collected fed on the dogs, indicating their possible role as an intermediate host, but filarial DNA was found only in Cx. pipiens, Anopheles maculipennis s.l. (Meigen), and Coquillettidia richiardii (Ficalbi). In rural environments, the DNA evidence indicated the presence of infective larvae of Dirofilaria immitis, whereas in urban areas, infective larvae of Dirofilaria repens were present. The role of Cx. pipiens as a vector for heartworm disease and subcutaneous infections in natural and artificial environments was confirmed, whereas Ae. caspius seemed refractory to the infection. The different role of the collected species is discussed. The vector competence of An. maculipennis and Cq. richiardii needs further investigation, because the importance of these species poorly represented, and the role of species such as Aedes albopictus (Skuse), characterized by a dominant diurnal activity pattern, has to be evaluated.

Abstract
PURPOSE To report the results of a three-year observational pilot study of lung cancer screening with low dose computed tomography (CT) and to present the study design of a randomised clinical trial named as ''Italung-CT''. MATERIALS AND METHODS Sixty (47 males and 13 females, mean age 64+/-4.5 years) heavy smokers (at least 20 packs-year) underwent three low-dose spiral CT screening tests one year apart on a single slice or multislice CT scanner. Indeterminate nodules were managed according to the recommendations of the Early Lung Cancer Action Project. RESULTS and Indeterminate nodules were observed in 33 (55%) of the subjects (60% at the baseline screening test, 24% at the first annual test and 16% at the second annual test). The size of the largest indeterminate nodule was <5 mm in diameter in 20 subjects, 10 of whom showed the nodule at the baseline test. Forty-five subjects (75%) completed the first annual test and 42 (70%) the second annual test. One (1.6%) prevalent lung cancer (adenosquamous carcinoma) and one (2.2%) incident lung cancer (small cell cancer at the first annual examination) were observed, as well as a pulmonary localisation of Hodgkin's lymphoma (at the second annual test). In addition, one subject underwent lung surgery for a chondromatous hamartoma. CONCLUSIONS The results of the pilot study are substantially in line with those of other observational studies of greater sample size. This justifies optimism about the reliability of the results in the screened arm of the ''Italung CT'' trial which has just begun.

Abstract
Protein aggregation is a notable feature of various human disorders, including Parkinson's disease, Alzheimer's disease and many others systemic amyloidoses. An increasing number of observations in vitro suggest that transition metals are able to accelerate the aggregation process of several proteins found in pathological deposits, e.g. alpha-synuclein, amyloid beta (Abeta) peptide, beta(2)-microglobulin and fragments of the prion protein. Here we report the effects of metal ions on the aggregation rate of human muscle acylphosphatase, a suitable model system for aggregation studies in vitro. Among the different species tested, Cu(2+) produced the most remarkable acceleration of aggregation, the rate of the process being 2.5-fold higher in the presence of 0.1 mM metal concentration. Data reported in the literature suggest the possible role played by histidine residues or negatively charged clusters present in the amino acid sequence in Cu(2+)-mediated aggregation of pathological proteins. Acylphosphatase does not contain histidine residues and is a basic protein. A number of histidine-containing mutational variants of acylphosphatase were produced to evaluate the importance of histidine in the aggregation process. The Cu(2+)-induced acceleration of aggregation was not significantly altered in the protein variants. The different aggregation rates shown by each variant were entirely explained by the changes of hydrophobicity or propensity to form a beta structure introduced by the point mutation. The effect of Cu(2+) on acylphosphatase aggregation cannot therefore be attributed to the specific factors usually invoked in the aggregation of pathological proteins. The effect, rather, seems to be a general related to the chemistry of the polypeptide backbone and could represent an additional deleterious factor resulting from the alteration of the homeostasis of metal ions in cells.

Abstract
Investigations were carried out in Padova town (Veneto region, NE Italy) to define the actual role of Aedes albopictus in the natural transmission of Dirofilaria nematodes, and to assess the risk that its presence might represent for veterinary and medical health. During summer 2000-2002 daytime captures of human-attracted mosquitoes were carried out in three areas of the town. The presence of filarial parasites in mosquitoes was evaluated by PCR, and sequencing confirmed species assessment. DNA extraction was performed separately on pools of the insect abdomen and thorax-head, to discriminate between Dirofilaria infected/infective specimens. A total of 2721 mosquitoes were caught and A. albopictus was the most abundant species (2534). Filarial DNA was found in 27.5% (19/69) of the abdomen pools formed with mosquitoes collected in summer 2000, and in 11.1% (16/144) and 4.9% (6/123) thorax-head pools coming from samplings 2001 and 2002, respectively. Filarial DNA was belonging to D. immitis and all studied areas harboured infective specimens. These results prove A. albopictus as natural vector of D. immitis in Italy. Moreover, they support the hypothesis that the presence of the mosquito could affect the transmission pattern of canine heartworm disease in urban environment and, considering the aggressive anthropophylic behaviour of the species (30-48 bites/h) proven in Padova town, could enhance the circulation of filarial nematodes from animals to humans.

Abstract
The invasive mosquito Aedes albopictus (Skuse) (Diptera: Culicidae) has become widespread in Italy during the past decade. Also Italy has foci of canine filariasis caused by Dirofilaria (Spirurida: Onchocercidae), due to subcutaneous D. repens Railliet & Henry as well as the dog heartworm D. immitis (Leidy) transmitted by various vector mosquitoes (Diptera: Culicidae). In 2002, at Fiumicino, west of Rome (Lazio Region), 17% of dogs were found to have D. repens microfilariae in peripheral blood. To evaluate the role of Ae. albopictus as a vector of Dirofilaria in this area, female mosquitoes were collected daily, June-October 2002, landing on dog or human bait in a rural house at Focene. Mosquitoes were maintained at 27 degrees C and 70% RH for 6 days, to allow development or purging of filaria larvae, then identified and frozen for subsequent molecular assay with filaria-specific ribosomal S2-S16 primers. To distinguish specimens harbouring infective L3 Dirofilaria larvae, DNA was extracted separately from the mosquito abdomen and head-thorax. Dirofilaria species were identified by sequencing, confirmed by polymerase chain reaction of positive specimens using primers specific for D. immitis and D. repens. Dirofilaria DNA was detected in 3/154 (2%) of Ae. albopictus females examined: D. repens DNA in head-thorax and abdomen of one collected 27th July; D. immitis in the abdomen of one collected 24th September; DNA of both D. immitis and D. repens in the head-thorax of one collected 11th October 2002. Thus Ae. albopictus is a potential vector of both Dirofilarias in Italy, representing risks for veterinary and human health.

Abstract
OBJECTIVE This was a prospective observational cohort study to evaluate the outcome and prognostic criteria of pregnancies with first-trimester bleeding and a gestational sac <or=16 mm without a demonstrable embryo. METHODS Criteria for admission into the study included: (1) first-trimester bleeding; (2) a transvaginal scan performed upon admission demonstrating a single intrauterine gestational sac with a mean diameter <or=16 mm and without a demonstrable embryo. The outcome variable was miscarriage, defined as pregnancy loss prior to 22 weeks. The following explanatory variables were considered: maternal age, menstrual age, size of the gestational sac, presence or absence of the yolk sac and subchorionic hematoma, and beta-human chorionic gonadotropin levels. The relationship of these variables with pregnancy failure was analyzed by stepwise logistic regression. RESULTS Of 50 patients, 32 (64%) underwent miscarriage. The receiver-operating characteristics (ROC) curve of the size of the gestational sac demonstrated a high level of statistical significance (area under the ROC curve 0.9080, P < 0.000001) and stepwise logistic regression revealed that this was the only variable independently correlated with the subsequent occurrence of miscarriage. DISCUSSION It is commonly accepted that in pregnant patients with first-trimester bleeding, demonstration by transvaginal ultrasound of an intrauterine gestational sac <or=16 mm without an embryo may be compatible with a viable pregnancy. Our results suggest that in general this finding is associated with a poor outcome, with miscarriage occurring in two-thirds of patients. When the sac is small for gestational age, the risk of miscarriage is greatly increased. In the present series, a gestational sac diameter less than -1.34 standard deviations of the mean was associated with pregnancy failure in over 90% of cases.

Abstract
OBJECTIVES To assess the visualization rate and size of the cavum septum pellucidum (CSP) by transabdominal sonography in normal fetuses throughout pregnancy. METHODS The CSP was prospectively researched and measured using an axial transventricular plane in 286 consecutive uncomplicated singleton pregnancies between 15 and 41 weeks of gestation. RESULTS The CSP was seen in 40% of cases at 15 weeks, 82% at 16-17 weeks, 100% at 18-37 weeks and 79% at 38-41 weeks. Compared to biparietal diameter (BPD), the visualization rate was 33% between 31 and 32 mm, 45% between 33 and 34 mm, 84% between 35 and 43 mm, 100% between 44 and 88 mm and 86% between 89 and 99 mm. Mean CSP width was 5.3 +/- 1.7 mm (range 2-9 mm). The CSP width increased with gestational age and BPD but with a slight decrease around term. CONCLUSIONS In normal fetuses the CSP should always be visualized between 18 and 37 weeks, or with a BPD of 44-88 mm. Failure to observe the CSP in this interval, or possibly the presence of a large CSP, may indicate abnormal cerebral development and warrant further investigation. Conversely, absence of the CSP prior to 18 weeks, or later than 37 weeks, is a normal finding.

Abstract
Current ultrasound equipment allows the antenatal identification of many central nervous system anomalies from early gestation. In selected cases, special techniques (transvaginal sonography, three-dimensional ultrasound, colour Doppler) may enhance the diagnostic potential. Diagnostic accuracy, however, remains heavily dependent upon the expertise of the sonologist. Fetal ultrasound is effective in identifying neural tube defects, although alpha-fetoprotein screening seems to yield a greater sensitivity. The sensitivity in the diagnosis of central nervous system malformations other than neural tube defects remains unclear because of the ascertainment biases of the few large prospective studies that have been carried out so far. Magnetic resonance imaging may play a major role in the evaluation of cases with suboptimal ultrasound visualization, or when specific anomalies are suspected, such as intracranial haemorrhage or migrational disorders.

Abstract
OBJECTIVE To assess the clinical significance of fetal isolated borderline cerebral lateral ventriculomegaly defined as a width of the atrium of the lateral cerebral ventricles of 10-15 mm in the absence of other sonographically demonstrable malformations. DESIGN Retrospective study of the outcome of fetuses with a sonographic diagnosis of isolated borderline cerebral lateral ventriculomegaly and review of the English-language literature. RESULTS Of 31 fetuses, two had chromosomal aberrations (trisomy 21 and trisomy 13) and three had neurological complications (one infant developed shunt-dependent hydrocephalus, one lissencephaly and one cerebral hemorrhage and periventricular leukomalacia). The literature search revealed eight independent studies. Including the present series, 234 cases were available for analysis. An abnormal outcome was documented in 22.8% of cases. Perinatal death occurred in 3.7%. Chromosomal aberrations, mostly trisomy 21, were present in 3.8%, malformations undetected at a second-trimester sonogram in 8.6% and neurological sequelae, mostly a mild to moderate delay in cognitive and/or motor development, were present in 11.5%. The risk of an abnormal neurological outcome was increased in females versus males (22.6% versus 4.6%, relative risk 4.892; 95% confidence interval 1.356-17.656), when the atrial width was 12 mm or more (13.9% versus 3.8%, relative risk 3.6, 95% confidence interval 1.035-12.846) and when the diagnosis was made in the second trimester versus later in gestation. CONCLUSIONS In most cases, isolated borderline cerebral lateral ventriculomegaly has no consequence. However, this finding carries an increased risk of cerebral maldevelopment, delayed neurological development and, possibly, chromosomal aberrations. The optimal management of these cases remains uncertain.

Abstract
OBJECTIVE To evaluate the possibility of an early diagnosis of skeletal dysplasias in high-risk patients. METHODS A total of 149 consecutive, uncomplicated singleton pregnancies at 9-13 weeks' amenorrhea, with certain menstrual history and regular cycles, were investigated with transvaginal ultrasound to establish the relationship between femur length and menstrual age, biparietal diameter and crown-rump length, using a polynomial regression model. A further eight patients with previous skeletal dysplasias in a total of 13 pregnancies were evaluated with serial examinations every 2 weeks from 10-11 weeks. RESULTS A significant correlation between femur length and crown-rump length and biparietal diameter was found, whereas none was observed between femur length and menstrual age. Of the five cases with skeletal dysplasias, only two (one with recurrent osteogenesis imperfecta and one with recurrent achondrogenesis) were diagnosed in the first trimester. CONCLUSIONS An early evaluation of fetal morphology in conjunction with the use of biometric charts of femur length against crown-rump length and femur length against biparietal diameter may be crucial for early diagnosis of severe skeletal dysplasias. By contrast, in less severe cases, biometric evaluation appears to be of no value for diagnosis.

Abstract
OBJECTIVE To evaluate the accuracy of cytologic screening in pregnancy through routine colposcopy and to confirm the safety of conservative management of cervical intraepithelial neoplasia (CIN) in pregnancy. STUDY DESIGN In total, 3,658 pregnant women, screened for cervical cancer with either cytology or colposcopy, were prospectively evaluated. Patients with abnormal findings underwent colposcopically directed biopsy and, in case of CIN, repeat cytology and colposcopy. Biopsy was repeated in case of suspected progression of the lesion. Suspected microinvasion was the only reason for diagnostic conization during pregnancy. After delivery, excisional treatment provided a final specimen from all patients. Diagnostic methods were compared. RESULTS Comparison between cytology and colposcopy showed 97.1% concordance with a few false positives (2.5%) and false negatives (0.2%). Abnormal cytology and colposcopy, as compared with histology, showed similar concordances, but the risk of underestimation by cytology was significantly higher (P < .05). Initial and final histology of the 63 cases of CIN and microinvasive carcinoma showed 88.9% concordance. Progression of the lesion was not observed. CONCLUSION These data do not justify combined use of cytology and colposcopy to improve screening for cervical cancer in pregnancy. Delayed treatment of CIN after delivery is safe.

Abstract
During a 5-year-period, 17 cases of congenital adenomatoid malformation of the lung were observed in the Department of Pediatric Surgery of Bologna University-S. Orsola-Malpighi Hospital; 16 cases were diagnosed in utero by ultra-sound. 13 patients had prenatal diagnosis between 21 and 23 weeks of gestation; 2 cases were diagnosed at 25 weeks and another one at 26 weeks. The other case came from another hospital, and the diagnosis was accidentally detected postnatally. In 3 cases the parents decided to terminate the pregnancy 3 cases had spontaneous improvement during the last weeks of gestation, and were perfectly normal at birth. One case was lost to follow-up; all remaining patients underwent resection. Among these patients only one was a nonsurvivor, while 9 have completely recovered. However, one patient developed persistent pulmonary hypertension, which could successfully be treated with drugs, another underwent laser treatment for laryngeal stenosis due to intubation. A special epidemiological information: 13 out 17 cases (76.5%) were female.

Abstract
OBJECTIVE To evaluate whether microcolposcopic topographic endocervical assessment reduces the failures of excisional treatment of cervical intraepithelial neoplasia (CIN). METHODS Three hundred fifty patients with colposcopic and histopathologic findings of endocervical CIN were recruited for excisional treatment. Three hundred forty-eight of these were randomized to have or not have microcolposcopy before excisional treatment. Measurement of endocervical lesion was the only aim of microcolposcopic evaluation. When an endocervical extension was available, the cone biopsy was cut according to microcolposcopic measurement. Excision status was evaluated and related to presurgical management on operative specimens. After excision, patients were followed-up for at least 5 years after treatment. Three hundred thirty (171 and 159 with and without preoperative microcolposcopy, respectively) patients completed the study. Disease persistences were defined by cytologic, colposcopic, and histologic results. Microcolposcopic value was defined as completeness of excision and/or lack of persistent disease. RESULTS. On surgical specimens, involved margins were detected in 19 (5.4%) cases. Presurgical microcolposcopy was performed in only one of these cases. The difference of incomplete excision between cases with or without microcolposcopy was statistically significant (P < .001). In patients who were followed-up, persistent disease was detected in one (0.6%) woman in the microcolposcopy group and in 16 (10%) women in the control group. Comparison between the two groups showed a significantly lower risk of persistent disease when presurgical microcolposcopy was performed (P < .001). CONCLUSION By measuring endocervical extension of the lesion, preoperative microcolposcopy allows individualized cones, thus improving the prognosis after excisional treatment of CIN.

Abstract
The aim of this study was to evaluate the diagnostic accuracy of transvaginal sonography vs. hysteroscopy in the preoperative staging of endometrial carcinoma, in order to establish the most appropriate surgical therapy. Transvaginal sonography and hysteroscopy were used preoperatively in 67 women with histologically proven endometrial carcinoma. Deep myometrial invasion (> 50%) was present at postoperative pathology in 26/67 (39%) women and spread to the cervix occurred in 11/67 (16%) women. Transvaginal sonographic examination was initially directed at assessing myometrial invasion, which was correctly predicted in 52/67 (78%) women. Transvaginal sonography demonstrated a sensitivity of 88% (23/26) and a specificity of 71% (29/41) for deep invasion, with a positive predictive value (PPV) of 66% (23/35) and a negative predictive value (NPV) of 91% (29/32). The accuracy of transvaginal sonography in detecting cervical involvement was 82% (55/67), and that of hysteroscopy was 72% (48/67): transvaginal sonography was slightly less sensitive (54% vs. 64%), but more specific (87% vs. 73%) than hysteroscopy. When cervical invasion was present, the PPVs of transvaginal sonography and hysteroscopy were 46% (6/13) and 32% (7/22), respectively, while the NPV was 91% for both techniques (49/54; 41/45). Our data show that the accuracy of transvaginal sonography was comparable with that of hysteroscopy in detecting cervical involvement. Therefore, in the majority of cases, when both techniques showed that disease was limited, the appropriately limited type of surgery would be performed. Conversely, detection of a myometrial invasion of > 50% or an extension to the cervix would lead to an unnecessarily extensive operation if this was the sole criterion used for making the decision.

Abstract
Essential thrombocythemia (ET) in pregnancy is associated with adverse perinatal outcome, which is likely due to thrombosis of the uteroplacental circulation. Obstetrical management is still controversial. Different therapeutic protocols have been adopted, including the use of aspirin, plateletpheresis, and interferon. We herein report a case of ET treated with interferon-2 alpha from 13 weeks gestation until term. Therapy was well tolerated, leading to a linear reduction of platelet and white blood cell count that rapidly returned within normal limits. A healthy, 3,020-g male infant was delivered at 40 weeks gestation. Albeit further experience is required, recombinant interferon-alpha 2a may play an important role in preventing complications in pregnant patients with ET.

Abstract
OBJECTIVE To define the accuracy of the umbilical artery Doppler flow velocity waveforms, according to different cut-off values, in predicting adverse perinatal outcomes among fetuses at high risk of hypoxic complications. SUBJECTS Two hundred and sixty-five pregnant women with diagnosis of small for gestational age fetus and/or pregnancy induced hypertension studied in four Italian ultrasound units. METHODS Prospective study. Serial Doppler ultrasound measurements of the umbilical artery were performed. Results were not available for clinical management. Cut-off curves, corresponding to different age-specific centiles of the pulsatility index distribution among pregnancies resulting in healthy newborns, regardless of birthweight, were computed by regression methods. Sensitivity, specificity, positive predictive value and negative predictive value of such cut-off curves, and of absent/reverse end-diastolic flow, in predicting different adverse outcomes were estimated. The adverse outcomes were: perinatal or neonatal death (OUTCOME 1). Death or Apgar<7 at 5' or need for admission to intensive care unit or other hypoxic related abnormalities (OUTCOME 2). Either OUTCOME 2 or birthweight<l0th centile (OUTCOME 3). Both OUTCOME 2 and birthweight<10th centile (OUTCOME 4). RESULTS The best accuracy was in predicting OUTCOMES 1 and 4. Positive predictive value increased strongly with higher cut-off curves while negative predictive value only decreased slightly. For absent/reverse end-diastolic flow, negative predictive value and positive predictive value were respectively 94% and 39% for death, and 81% and 72% respectively for OUTCOME 2. For the 95th centile curve the corresponding figures were 96%, 33% and 84%, 67%. The 60th centile curve had a 85% and 74% sensitivity value for death and OUTCOME 2 respectively, but the corresponding positive predictive values were 18% and 40% only. CONCLUSIONS The findings of an absent end diastolic flow or of pulsatility index values above the 95th centile curve strongly suggest it is time to deliver the fetus. The 60th centile curve is the most suitable to recognize fetuses at risk for abnormal outcome, but early delivery should be avoided because of its low positive predictive value.

Abstract
Ultrasonography has been used increasingly in the first trimester to identify fetal anomalies as early as possible in gestation. First trimester sonographic screening may detect a greater proportion of aneuploid fetuses than sonography performed later in pregnancy, and it may allow determination of potential markers for prediction of chromosomal anomalies.

Abstract
To assess the efficacy of the Doppler velocimetry of the uterine and umbilical arteries as a screening test for preeclampsia and fetal growth retardation, we studied 916 low risk pregnancies. The S/D ratios of the uterine and umbilical arteries were obtained at 19 to 24 weeks and at 26 to 31 weeks of gestational age. Mean values, receiver operator curves, and the diagnostic accuracy of the tests were calculated for the following end-points: (1) pregnancy-induced hypertension, (2) low birth weight for gestational age, (3) small for gestational age with abnormal outcome, (4) pregnancy-induced hypertension needing preterm delivery. The prevalences for these outcomes were 3.4%, 4.6%, 1%, and 0.7%, respectively. The study was blinded. The umbilical and uterine artery S/D ratios were significantly higher in the abnormal than in the normal outcome group. When uterine arteries were studied at 19 to 24 weeks, sensitivity was 59% in the detection of pregnancy-induced hypertension, 11% in the detection of small for gestational age fetuses, 33% in the detection of small for gestational age fetuses with abnormal outcome, and 83% in the detection of pregnancy induced hypertension needing preterm delivery; the corresponding values for specificity were 69%, 94%, 94%, and 68%. At 26 to 31 weeks the sensitivity values were respectively, 69%, 58%, 75%, and 100% and specificity values were 80%, 59%, 39%, and 79%. When umbilical arteries were studied at 19 to 24 weeks, sensitivity was 38% in the detection of pregnancy-induced hypertension, 46% in the detection of small for gestational age fetuses, 78% in the detection of small for gestational age fetuses with abnormal outcome, and 67% in the detection of pregnancy-induced hypertension needing preterm delivery. The corresponding values of specificity were 74% for all four groups. At 26 to 31 weeks the sensitivity values were 38%, 43%, 87%, and 67%, respectively, and specificity values were 80% for all four groups. We concluded that Doppler examinations of the uterine and umbilical arteries can detect, at midpregnancy, the severe forms of pregnancy-induced hypertension and small for gestational age fetuses but they cannot be used to screen a low risk population in which the prevalence of the disease is low, and hence the positive predictive value is low.

Abstract
Our objective was to assess the clinical significance of the sonographically derived head-to-abdomen circumference ratio in small-for-gestational-age (SGA) fetuses. The head-to-abdomen ratio was determined in 134 singleton SGA fetuses without ultrasound evidence of malformations at 26-40 weeks' gestation. Data were collected regarding antenatal surveillance, umbilical artery Doppler velocimetry and neonatal outcome. In SGA fetuses, the head-to-abdomen ratio, adjusted for gestational age, had a normal frequency distribution, positively skewed with regard to fetuses with normal birth weight. An elevated head-to-abdomen ratio was found in 56 SGA fetuses (42%), and was associated with increased perinatal mortality (odds ratio 3.27; 95% confidence internal 1.04-9.34), lower birth weight (1533 +/- 635 g vs. 2022 +/- 655 g, p < 0.0001) and lower gestational age at delivery (34 +/- 3.6 weeks vs. 36.3 +/- 3.6 weeks, p < 0.005). However, logistic regression revealed that the most powerful antenatal determinants of pregnancy outcome were Doppler velocimetry of the umbilical artery, followed by biophysical profile, while no independent correlation was found with the head-to-abdomen ratio. The existence of two distinct categories of SGA fetuses, 'symmetric' and 'asymmetric', remains uncertain. An elevated head-to-abdomen ratio is an adverse risk factor for pregnancy outcome. However, this parameter has no clearcut clinical value when umbilical artery Doppler velocimetry and biophysical antenatal testing are available.

Abstract
The utility of Doppler ultrasonography as a means of assessing potential alterations of vascular resistance prior to fetal or maternal compromise is very attractive. We investigated this relationship by prospectively performing Doppler studies of the fetal umbilical artery in 56 diabetic patients, 14 of whom had varying degrees of vascular complications. When regression curves were established for the S/D ratio, the Pourcelot index, and the resistance index of the fetal umbilical artery, the mean Doppler values were higher in diabetic patients with vasculopathy than in nondiabetic control patients or in diabetic patients without vasculopathy. The third trimester S/D ratio was greater than 3.0 in almost 50% of patients with vasculopathy. A tendency toward adverse outcomes was observed at S/D ratios approaching 4.0. Statistically significant correlations were found between elevated Doppler indices and maternal vasculopathy associated with hypertension and worsening renal insufficiency. Intrauterine growth retardation and neonatal metabolic complications were also significantly correlated with elevated Doppler indices. There was, however, no correlation between Doppler indices and glucose values, although most were within a euglycemic range. The aforementioned data indicate an increased resistance circuit among diabetics with vasculopathy, which may reflect a relative reduction in basal uteroplacental blood flow and the need for cautious interpretation of Doppler indices in these patients.

Abstract
A prospective cross-sectional study was performed in 248 pregnant women between 5 and 12 weeks' menstrual age with transvaginal sonography to establish biometric charts of the gestational sac, embryonic crown-rump length and biparietal diameter, amniotic sac and yolk sac to be used for assessment of gestational age and prediction of pregnancy failure. Polynomial regression analysis was applied and demonstrated a statistically significant positive correlation that could be described in all cases as a quadratic function, between gestational age and all the measurements with the exclusion of the yolk sac. Centile charts of both growth models and dating models were tabulated. The interrelationship between different measurements, including the gestational sac, crown-rump length, biparietal diameter and amniotic sac was also evaluated to produce age-independent charts. The dating model of the crown-rump length was found to have mean values similar to those described in transabdominal studies. The 95% reference interval was, however, 8.4 days, which was not lower than those reported in most transabdominal studies. It was concluded that transvaginal sonography was more able than the abdominal route to allow measurement of the crown-rump length in very early gestation, but did not yield a greater accuracy in predicting gestational age.

Abstract
Transvaginal ultrasound was performed upon admission of 127 patients with a clinical suspicion of ectopic pregnancy in association with human chorionic gonadotropin (hCG) determination. Failure to visualize with sonography an intrauterine gestational sac with an hCG level superior to 1000 mIU/ml identified 25/42 tubal pregnancies with a positive predictive value of 86% and a specificity of 93%. Abnormal adnexal findings occurred in 95% of the ectopic pregnancies. Extrauterine gestational sacs with or without embryos could be confidently detected in 19 ectopic pregnancies (45%). A complex adnexal mass was seen in 19 cases and yielded a positive predictive value of 90% (19/21). Adnexal gestational sacs and complex masses were seen more frequently in those ectopic pregnancies with an hCG level above 1000 mIU/ml but the difference was not significant (100% versus 78%). Simple adnexal cysts were found more frequently in intrauterine pregnancies, and fluid in the cul-de-sac was also not indicative of ectopic pregnancy (positive predictive value, 29%). Transvaginal ultrasound has a primary role in the diagnosis of ectopic pregnancy. The combined use of uterine and adnexal sonography associated with elevated hCG levels allows a definitive diagnosis in the vast majority of cases at a very early stage, when the chances for a successful conservative treatment are greater.
