Abstract
The O/ME-SA/Ind-2001d has been the main foot-and-mouth disease virus (FMDV) lineage responsible for FMD epidemics outside the Indian subcontinent from 2013 to 2017. In 2014, outbreaks caused by this FMDV lineage were reported in Maghreb, where it was initially detected in Algeria and Tunisia and later in Morocco. This was the first incursion of an FMDV type O of exotic origin in the Maghreb region after 14 years of absence. In this study, we report analyses of both VP1 and whole-genome sequences (WGSs) generated from 22 isolates collected in Algeria and Tunisia between 2014 and 2015. All the WGSs analysed showed a minimum pairwise identity of 98.9% at the nucleotide level and 99% at the amino acid level (FMDV coding region). All Tunisian sequences shared a single putative common ancestor closely related to FMDV strains circulating in Libya during 2013. Whereas sequences from Algeria suggest the country experienced two virus introductions. The first introduction is represented by strains circulating in 2014 which are closely related to those from Tunisia, the second one, of which the origin is more uncertain, includes strains collected in Algeria in 2015 that gave origin to the 2015 outbreak reported in Morocco. Overall, our results demonstrated that a unique introduction of O/Ind-2001d FMDV occurred in Maghreb through Tunisia presumably in 2014, and from then the virus spread into Algeria and later into Morocco.

Abstract
BackgroundThere is growing interest in reproductive issues in patients with Spondyloarthritis (SpA) and Psoriatic arthritis (PsA).ObjectivesTo describe a real-life cohort of prospectively-followed pregnancies in SpA and PsA patients, focusing on obstetric outcome and on flare during pregnancies and post-partum.MethodsData on SpA and PsA pregnancies prospectively-followed in 2 European pregnancy clinics from 2010 to 2021 were retrospectively analysed.Disease activity was assessed using ASDAS-CRP or DAS28-CRP according to the main involvement (peripheral or axial). Disease flare was defined as the need to treatment modification (introduction or increase ≥5mg/day of prednisone, introduction of cDMARD or bDMARD). Miscarriages were excluded from the analysis of flares.ResultsData on 122 pregnancies (53 PsA and 69 ‘other SpA’: 39 axialSpA, 20 undifferentiated SpA, 6 IBD-related SpA, 4 reactive arthritis) in 102 patients (median age at conception: 34 [IQR: 31-36] years; median disease duration: 72 [24-132] months) were collected.We recorded 98 (86%) live births and 16 (14%) miscarriages (8 missing data).Cesarean section was performed in 15/98 (15%) cases. Median week of gestation at delivery was 39 [38-40]; 8 preterm births (<37 week of gestation) and 2 severe preterm births (<34 week of gestation) occurred. There was no difference between PsA or ‘other-SpA’ concerning pregnancy outcome and route of delivery.Fourty-two pregnancies (40%) had at least 1 flare during pregnancy; 7 pregnancies had more than 1 flare. Overall, there were 13, 24 and 12 flares in the 1st, 2nd and 3rd trimester, respectively.A higher frequency of patients with axial involvement was observed in the ‘flare’ group as compared to pregnancies without flare (83% vs 59%, p=0.02) (Table 1).Table 1.Comparison between ‘flare’ and ‘without flare’ groups.FLARE (42)WITHOUT FLARE (64)pAge at conception (years)33 (31-37)33 (31-35)0.88Disease duration at conception (months)71 (24-120)60 (24-137)0.74PsA13 (31%)31 (48%)0.11‘Other SpA’29 (69%)33 (52%)0.11Axial involvement35 (83%)38 (59%)0.02Peripheral involvement30 (%)54 (%)0.17bDMARD useAny time before pregnancy16 (38%)19 (30%)0.49Stop at + pregnancy test/1st trimester8 (19%)4 (6%)0.09Start/continue 1st trimester7 (17%)10 (16%)0.89Start in 2ndtrimester5 (12%)00.02Start in 3rd trimester2 (5%)00.30Post-partum flare11/34 (32%)22/49 (45%)0.36Continuous variables were compared using Mann-Whitney test; categorical variables were compared using Chi-square with Yates’ correction or Fisher’s exact test.Medications resumed to treat flare were steroids (29 pregnancies), csDMARDs (14 pregnancies) and TNF-inhibitors (7 pregnancies: 5 during the 2nd and 2 during the 3rd trimester).A post-partum flare was registered in 33/83 (40%) of cases, without difference between ‘flare’ group vs ‘without flare’ group (Table 1), as well as between PsA vs ‘other SpA’ pregnancies (47% vs 33%, p=0.2).ConclusionIn this cohort of SpA pregnancies, 40% experienced a flare during pregnancy and 40% during post-partum. Flares occurred more frequently in the 2nd trimester and especially in patients with axial involvement, requiring the start of a TNF-inhibitor during the 2nd or the 3rd trimester in 7 pregnancies. Having a flare during pregnancy was not associated with a post-partum flare.Disclosure of InterestsNone declared

Abstract
Introduction Attention Deficit / Hyperactivity Disorder (ADHD) is a highly prevalent neurodevelopmental condition characterized by inattention, motor hyperactivity and impulsivity. ADHD cognitive and behavioral presentation is characterized by a high heterogeneity (APA, 2013). Indeed, a complex diagnostic process, that considers several validated tools, is, to date, necessary. Objectives The main aim is to develop supervised machine learning (ML) algorithms that could be used to support the diagnostic process for ADHD, by identifying the most relevant features in discriminating between the presence or absence of the ADHD diagnosis in children. Methods We analyzed data from 342 children (Mean age: 8y 8m ± 1y; 61 F) referred for possible ADHD symptomatology. Assessments were performed by an expert clinician and through questionnaires: Social Responsiveness Scale (SRS), Child Behavior Checklist (CBCL), Conners Rating Scale for Parents (CPRS) and for Teachers (CTRS). Data were analyzed using a decision tree classifier and random forest algorithms. Results The decision tree model performed an accuracy of 0.71. The random forest model that was identified as the best tested, performed an accuracy of 0.77 (Figure 1) and it identified as most informative parent- and teacher-rated DSM-oriented ADHD symptoms (Figure 2). ![]()

Figure 2: Ranking of variables importance. Conclusions A random forest classifier could represent an effective algorithm to support the identification of ADHD children and to simplify the diagnostic process as an initial step. The use of supervised machine learning algorithms could be useful in helping the diagnostic process, highlighting the importance of a personalized medicine approach.

Abstract
Introduction Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by lack of self-regulation and deficits in organizing behaviors in response to emotional stimuli. Methylphenidate (MPH) is one of the most effective psychostimulant drugs for ADHD, however, a possible predictive utility of brain hemodynamic data related to MPH administration and its relation to clinical symptomatology is still not clear. To address these questions, we used Near Infrared Spectroscopy (NIRS) technology, a non-invasive optical technique that allows to investigate the effect of psychopharmacological treatment on cortical hemodynamics. Methods Twenty children with ADHD underwent a three-waves study and 25 healthy controls were recruited at W1. At W2 children with ADHD received first MPH administration and at W3 they reached the titration phase. At each phase children performed - during NIRS recording - an emotional continuous performance task with visual stimuli of different emotional content. Clinical data were also collected at W1 and W3. We investigated the relationship among the difference between NIRS activation at W2 and W1 (Delta1) and W3 and W2 (Delta2), for each subject, task condition and brain region. Lastly, we investigated correlations between the Delta1 and clinical symptomatology indexes at W1 and between Delta2 and clinical data at W3. Conclusions Our study results suggest that hemodynamic changes in right prefrontal region probably induced by first MPH administration could predict hemodynamic changes related to MPH titration phase. These biological indexes could be associated to clinical evidences related not only to core ADHD symptoms but also to affective correlates. Disclosure No significant relationships.

Abstract
Introduction Epigenetics hypothesizes a crucial link between postnatal risk factors, individual response to stress, DNA methylation and psychiatric symptomatology changes during life. Objectives We analyzed methylation within two gene exons: NR3C1 and SLC6A4, which are involved in responses to environmental stressors. We investigated the relationship between methylation, postnatal risk factors and psychopathology assessed by Child Behavior Checklist (CBCL) in our help-seeking sample evaluated in infancy (W1), preadolescence (W2) and adult life (W3). Methods Postnatal risk factors data were collected at W1 in 205 clinical subjects (156 M, 49 F; age=9,13±1,95). The CBCL scores were collected at W1 and W2 (W2 age=14,52±2,12). Data regarding methylation were collected at W2. At W3 we are also collecting clinical scores. A Spearman correlation coefficient was calculated between methylation percentage and clinical data at W2. The externalizing and internalizing trajectories were evaluated through repeated measure ANOVA with postnatal risk factors (presence/absence) as between-groups factor. Results Significant associations were found between methylation and internalizing and total clinical scores (Table 1). The rm-ANOVA results showed a significant interaction between the CBCL internalizing score and presence/absence of postnatal risk, with higher internalizing problems in subjects that were exposed to postnatal risk factors. This effect was significant at W2 but not at W1 (Figure 1).![]() ![]() Conclusions Psychopathological symptoms trajectories could depend on epigenetics and early environmental risk factors. Further analyses will address a Linear Discriminant Analysis to proceed to a machine learning oriented approach. Disclosure No significant relationships.

Abstract
Introduction Our 15-years follow-up ReMIND project aims to re-assess an epidemiological and a clinical sample of adults (Wave 3), who were assessed in preadolescence (Wave 1) and adolescence (Wave 2), to evaluate symptoms trajectories and their relationship with genetic/epigenetic data, environmental risk factors and neuroimaging measures. Objectives Here, we depict preliminary results regarding the epidemiological sample. Methods We assessed internalizing and externalizing symptoms in 40 italian subjects (25 F) from general population at three waves (W1 mean age: 12±0,82; W2 mean age: 17±0,88, W3 mean age: 28±1), through the Child Behavior Checklist (W1 and W2) or the Adult Self Report (W3), and perinatal risk factors through a socio-anamnestic questionnaire, by a new online platform (MedicalBit). We analyzed symptoms trajectories and their relation with perinatal risk factors through a repeated measures multivariate analysis of variance (rm-MANOVA). Results rm-MANOVA results show that high number of perinatal risks was significantly associated with higher internalizing symptomatology in preadolescence but not in adolescence and adult life. The mean difference was 8 T-points. The same trend is evident in adolescence but not in adult age (Graph 1). Perinatal risk factors did not have a significant effect on externalizing symptoms at any time point, despite a non-significant trend is evident (Graph 2).![]() ![]() Conclusions Our preliminary results suggest a trend of increased internalizing symptoms from childhood to adulthood and a significant role of perinatal risk factors in pre-adolescence. Further investigations are necessary to better understand symptoms trajectories and the role of biological and environmental factors. Disclosure No significant relationships.

Abstract
We conducted a cross-sectional study during 2013 to quantify the serological prevalence of peste des petits ruminants (PPR) infection and to investigate host factors associated with PPR infection in small ruminants in Libya. A two-stage sampling design was carried out. A total number of 148 flocks owning at least 100 heads each were randomly selected. Sixteen to forty-eight samples were collected from each selected flock. A total number of 3,508 serum samples from unvaccinated animals were collected and analysed at IZSLER Brescia, Italy, by using competitive ELISA, IDvet innovative diagnostics (IDvet 310, France). The overall serological prevalence among SR was 33% (95% CI: 31.4-34.5). Significant differences between the prevalence in the geographical branches were observed. The lowest prevalence level was observed in Zawiyah branch (16.1%), whereas the highest value was obtained for the Sabha branch (56.8%). Considering the age, a serological prevalence of 24.7%, 31.5% and 42.1% was observed in SR <1 year, between 1 and 2 years and more than 2 years, respectively. Statistically significant differences (p < .001) in the sero-prevalence levels were also observed between the age groups. Our findings suggest that the southern part of Libya could be more exposed to the infections coming from the neighbouring countries and this should be better investigated to correctly identify wherever specific entry points can be considered at higher risk than others. The results also confirmed the endemic status of PPR in Libya, with a constant exposure to the infection of the animals during their life. In the framework of the global strategy for control and eradication of PPR, our results, even if obtained by a preliminary study, can contribute to the assessment of the epidemiological situation of PPR in Libya as required by the Stage 1 of the plan.

Abstract
BACKGROUND The Pulmonary Embolism (PE) Severity Index (PESI) is a clinical prognostic rule that accurately classifies PE patients into five risk classes with increasing mortality. PESI score has been validated in studies with a relatively short-term follow-up and its accuracy in predicting long-term prognosis has never been established. METHODS Consecutive patients admitted to the tertiary care hospital of Varese (Italy) with an objectively diagnosed PE between January 2005 and December 2009 were retrospectively included. Information on clinical presentation, diagnostic work-up, risk factors, treatment and mortality during a 1-year follow-up was collected. RESULTS Five hundred and thirty-eight patients were enrolled in this study. The mean age was 70.6 years (± SD 15.2), 44.4% of patients were male, and 27.9% had known cancer. One-year follow-up was available for 96.1% of patients. The overall mortality rate was 23.2% at 3 months, 30.2% at 6 months and 37.1% at 12 months. The discriminatory power of the PESI score to predict long-term mortality, expressed as the area under the ROC curve, was 0.77 (95%CI, 0.72-0.81) at 3 months, 0.77 (95%CI, 0.73-0.81) at 6 months and 0.79 (95%CI, 0.75-0.82) at 12 months. The PESI score confirmed its accurate prediction in patients without cancer. Simplified PESI had a similar overall accuracy to the original PESI at 3 and 6 months, but this was significantly lower at 1 year. CONCLUSIONS The results of this study suggest that PESI score may also be an accurate tool to define the 6-month and 1-year mortality rates in PE patients.

Abstract
To validate the use of serology in substantiating freedom from infection after foot-and-mouth disease (FMD) outbreaks have been controlled by measures that include vaccination, 3551 sera were tested with six assays that detect antibodies to the non-structural proteins of FMD virus. The sera came from naïve, vaccinated, infected and vaccinated-and-infected animals; two-thirds from cattle, the remainder from sheep and pigs. The assays were covariant for sensitivity, but not necessarily for specificity. A commercial kit from Cedi-diagnostics and an in-house assay from IZS-Brescia were comparable to the NCPanaftosa-screening index method described in the Diagnostic Manual of the World Animal Health Organisation. Using these three tests the specificity and sensitivity for the detection of carriers in vaccinated cattle approaches or exceeds 99% and 90%, respectively.

Abstract
A blocking ELISA that differentiated foot-and-mouth disease virus (FMDV) infected animals from vaccinated animals was developed which uses baculovirus expressed FMDV 3ABC non-structural protein as antigen and monoclonal antibody against FMDV 3ABC non-structural protein as capture and detector antibody. Sera from naive, vaccinated and infected cattle, sheep and pigs were examined. The specificity of the test was high. Non-specific reactions observed in particular in sera of cattle and sheep could be removed by filtration and inactivation. Positive reactions were obtained for sera from cattle infected with all seven serotypes of FMDV. The test detected antibodies from days 7 or 9 following experimental infection of non-vaccinated cattle and sheep, and in cattle strong positive reactions persisted for up to 395 days after infection. In vaccinated cattle that became carriers after challenge with homologous FMDV, positive reactions were obtained in all but one case. In some of these cattle the antibody response was detected late in comparison to the non-vaccinated infected cattle. The test gave results that compared favourably with two commercial ELISA's when used to test sera from cattle, pigs and sheep collected after experimental or natural infection. The blocking ELISA based on recombinant FMDV 3ABC antigen and a monoclonal antibody to 3ABC is a promising tool for FMD control and eradication campaigns, where vaccination has been carried out.

Abstract
Recent devastating outbreaks of foot-and-mouth disease (FMD) in Europe have reopened the discussion about the adequacy of the non-vaccination strategy implemented by the EU in 1991. Here we describe the evaluation of a new commercially available test kit for the discrimination between vaccination and infection. The test is based on the detection of antibodies against the recombinant non-structural (NS) protein 3ABC. In contrast to immunization with vaccines free of 3ABC, these antibodies are elicited as a consequence of infection. Testing more than 3600 negative sera from several countries revealed a specificity of > 99% for bovine, ovine, and porcine samples. Antibodies specific for 3ABC can be detected as soon as 10 days post-infection. As compared with the occurrence of antibodies against structural proteins of FMDV, anti-3ABC antibodies can be detected 5-10 days later, depending on the species. No anti-3ABC antibodies were detected in sera from vaccination experiments or in field sera from vaccinated animals. However, anti-3ABC antibodies can be detected in vaccinated animals upon challenge. These results provide evidence that this test can facilitate the use of vaccines in new strategies against FMD.

Abstract
OBJECTIVE Molecular variants of the angiotensinogen (AGT) and the angiotensin II type 1 receptor (ATR) genes have been associated with the risk of coronary artery disease (CAD) and myocardial infarction (MI), but data so far available are conflicting. The primary object of the paper is to verify this possible association by a rigorous, angiographically controlled study in a large sample of patients with or without multi-vessel CAD. DESIGN We designed a large case-control study in Italian patients candidates for coronary artery bypass grafting, with angiographically documented multi-vessel CAD, compared to subjects with angiographically documented normal coronary arteries. METHODS AND RESULTS AGT M235T and ATR A1166C gene polymorphisms were analysed in 699 subjects; 454 patients were candidates for coronary artery bypass grafting, having angiographically documented (mainly multi-vessel) CAD. An appropriate documentation of previous MI was obtained from 404/454 (89%, 247 with and 157 without MI). Subjects (n = 245) with angiographically documented normal coronary arteries, were included as control group (CAD-free group). CAD patients had a substantial burden of conventional risk factors as compared with controls free of coronary atherosclerosis. Age, gender, smoking habit and number of stenosed vessels were the only differences between patients with or without previous myocardial infarction, who were similarly exposed to the other conventional risk factors (including hypertension). AGT M235T and ATR A1166C allele and genotype frequencies were similar between CAD and CAD-free patients. In the CAD group, AGT 235T allele was found more frequently in subjects with a previous myocardial infarction (0.494 versus 0.414; P < or = 0.05). By logistic regression, homozygosity for AGT 235T variant appeared to confer 1.9-fold increased risk for MI in both the univariate and the multivariate (adjusted for age, gender, smoking habit and number of stenosed vessels) model. CONCLUSIONS AGT 235 T homozygous patients with multivessel CAD have an increased risk of myocardial infarction as compared with subjects with clinically similar phenotype but different genotype.

Abstract
Genes that influence the renin-angiotensin system have been investigated in recent years as potential etiologic candidates of cardiovascular and renal diseases. In atheromatous renal artery stenosis (RAS), a condition characterized by persistent activation of the renin-angiotensin system, the study of these genes may be of particular relevance. We evaluated angiotensin-converting enzyme (ACE) insertion/deletion, angiotensinogen (AGT) M235T, and angiotensin II receptor (ATR) A1166C polymorphisms in relation to the occurrence of RAS. We studied 58 patients with angiographically documented RAS; 102 normotensive subjects with normal coronary arteries and no history or clinical or instrumental evidence of atherosclerosis in other vascular districts were considered the control group. Patients had a significantly higher D allele frequency (0.70 versus 0.55; chi(2) 6.88, P=0.01; odds ratio [OR] 1. 9, 95% CI 1.17 to 3.07) than did the control population; 48.3% of patients were homozygous for DD (chi(2) 6.62, P<0.05; OR 2.04, 95% CI 1.05 to 3.95); and only 8.6% carried the II genotype (OR 0.34, 95% CI 0.19 to 1.47). No significant association was found for AGT M235T and ATR A1166C. Our results suggest a predisposing role for ACE genetic polymorphism in the development and progression of atheromatous RAS.

Abstract
Rabbit hemorrhagic disease virus (RHDV) is a noncultivable calicivirus that infects rabbits (Oryctolagus cuniculus) and causes epidemics of an acute fatal hepatitis. In 1997 we identified two RHDV isolates from geographically distant Italian regions, which differed antigenically from the reference strain RHDV.Bs89. In fact, they were not reactive with mAb 1H8, that is able to protect rabbits from RHD and showed a low reactivity with the rabbit convalescent serum raised against RHDV.Bs89. Experimental infection of rabbits with either RHDV isolates confirmed their high pathogenicity and their peculiar antigenic profile; nevertheless, rabbits vaccinated with the current vaccine were protected against challenge infection with these isolates. Sequence comparison definitely demonstrated that the two isolates originated from the same RHDV variant and that the similarity of their structural protein (VP60) sequences with the RHDV.Bs89 is equal to 93%. This variant was named RHDVa since shows consistent genetic and antigenic differences from the wild-type RHDV. In particular, 44% of amino acid substitutions in RHDVa VP60 were located between amino acids 344 and 370, where the similarity with RHDV.Bs89 drops to 70%, suggesting that this region probably contains the epitope recognized by mAb 1H8. In addition, this paper presents preliminary data concerning the amino acids of VP60 involved in the hemagglutination site of the virus.

Abstract
Breast cancer in women 35 years old or younger is unusual. It accounts for 1-3.6% of all breast cancers but is the leading cause of cancer mortality in women 15-35 years old. The diagnostic delay, with T2 or more advanced cancer at clinical presentation, is due to the patient's age and the opinion of low mammographic reliability for cancer diagnosis in this age group. To assess the usefulness of mammography in breast cancer patients aged 35 years or younger, we reviewed the clinical, mammographic and histologic data of 65 cancers collected in 7 breast diagnosis and counseling centers in Lombardy. Fifty-three patients (81.5%) were referred for a palpable breast mass, which was a T2 or more advanced cancer in 23 cases. Mammography showed malignant patterns (spiculated opacities, clusters of microcalcifications, casting, branching and ductal type calcifications) in 31 patients (47.7%). Mammography was not definitive but correctly suggested further examinations in 30 women and it had only 4 false negatives. Ultrasonography performed in 43 patients was negative in 3 (7%), pathologic and pathognomonic for cancer in 27 (62.8%) and pathologic but not indicative of malignancy in 13 (20.2%). The cytologic or histologic diagnosis of breast cancer was made under US guidance in 24 cases. In women aged 35 years or younger mammography was effective in identifying breast cancers; US and fine-needle aspiration biopsy (FNAB) complete mammography. We believe that mammography can be a valuable screening tool in young women at high risk for breast cancer because of family history.

Abstract
Resistance to activated protein C (APC-R) is at present considered the most frequent laboratory abnormality in patients with deep vein thrombosis. An increased risk for venous thrombosis is associated with the use of oral contraceptives (OCs). We recently described a statistically significant association between APC-R status and oral contraceptives use in a healthy group of women. We re-evaluated 50 healthy women taking low-dose combination OCs in order to consider a possible correlation between the APC sensitivity ratio (APC-SR) and different oral contraceptive formulations. Seven women showed an APC ratio < or = 2 (APC-resistant). Only one of the seven women was found to be heterozygous for Leiden factor V mutation. We observed no significant differences between normally sensitive and APC-resistant women in terms of duration of OC use, amount of estrogenic or progestogenic dose, or type of formulation. We conclude that APC-resistance associated with oral contraceptives use seems to occur only in predisposed subjects (in our results, about 12% of the healthy population).

Abstract
To detect in children with tetralogy of Fallot (ToF) the prevalence of associated cardiac anomalies in syndromic and isolated cases, the additional cardiac defects of 150 consecutive patients with ToF (102 isolated and 48 syndromic cases) were evaluated by review of echocardiographic, angiocardiographic, and surgical reports. Syndromic patients were classified into groups with branchial arch defects, Down syndrome, and other genetic conditions. ToF is significantly associated with additional cardiac malformations in patients with branchial arch (11 of 21, p <0.01) and Down (10 of 20, p <0.0001) syndromes. The subarterial ventricular septal defect with deficiency of the infundibular septum (4 of 21, p <0.01) and the right aortic arch (6 of 21, p <0.05) were prevalent in patients with branchial arch syndromes, whereas atrioventricular canal (10 of 20, p <0.0001) was associated with ToF in patients with Down syndrome. Peculiar anatomic cardiac patterns are present in children with ToF and may alert the cardiologist to look at additional cardiac anomalies. Moreover, the presence of some associated cardiac anomalies may suggest careful clinical evaluation for genetic syndromes.

Abstract
UNLABELLED Among 41 consecutive children with classic Noonan syndrome, 27 patients (66%) presented cardiac anomalies. Eight patients (19.5%) had a congenital anomaly of the mitral valve consisting of 5 with partial atrioventricular canal defect and 3 with anomalous insertion of the mitral valve on the ventricular septum. Five patients (12%) presented with a significant left ventricular outflow tract obstruction caused by the anterior leaflet of the mitral valve: two cases with atrioventricular canal and three cases with isolated anomalous insertion of the mitral valve. Echocardiography is the best tool for the diagnosis. Cardiac defects of patients with Noonan syndrome may be explained on the basis of anomalies of the extracellular matrix involving cardiac valves including the mitral valve. CONCLUSION In children with Noonan syndrome and left ventricular hypertrophy a careful echocardiographic assessment of the mitral valve should reveal those in whom the left ventricular outflow tract obstruction is anatomical in nature.

Abstract
We report 2D-echocardiographic and angiocardiographic assessment of 28 cases of visceral heterotaxia with left atrial isomerism, with particular emphasis on infundibular ventricular morphology. Ventricular D-loop was present in 15 cases (52.6%), and ventricular L-loop in 13 (46.4%); 25/48 patients had concordant ventricular loop and cardiac position (89.3%). In 18 patients (64.3%) there were 2 balanced ventricles; of the other 10 patients, 9 (32.1%) presented right and 1 (3.6%) left ventricular dominance. Ventricular septal defect was present in 12 cases (42.8%). Ventriculo-arterial connections were concordant, with "normally related" great arteries in 9/15 cases with ventricular D-loop (60%). In these cases, ventricular morphology, connections and relations of the great arteries were typical of situs solitus. In the remaining 6 patients there was double-outlet right ventricle, also with normally related great arteries. In 12/13 cases (92.3%) with ventricular L-loop ventriculo-arterial connections were concordant with "mirror image normally related" great arteries. In these cases, ventricular morphology, connections and relations of the great arteries were typical of situs inversus. In one patient there was double-outlet right ventricle, also with mirror image normally related great arteries. Twelve patients (42.8%) had pulmonary stenosis and 5 had a systemic outflow obstruction (17.8%). From these observations we conclude that ventriculo-infundibular morphology, either of situs solitus-type or of situs inversus-type, is a typical anatomical feature of left atrial isomerism. These results may have important implications in the diagnosis and in the surgical management of patients with left atrial isomerism.

The patterns of pulmonary circulation were assessed by angiography in a series of 24 patients with right atrial isomerism (asplenia syndrome) and pulmonary atresia. Mean age at catheterization was 21.5 days (range 1 day-11 months). The pulmonary arteries were confluent in 22 cases (91.7%). Eighteen patients (75%) had ductus-dependent pulmonary circulation in presence of confluent pulmonary arteries, similar to cases of pulmonary atresia combined with complex congenital heart disease. The ductus appeared in continuity with the aortic arch, shaping an acute angle with the descending aorta, as in cases of pulmonary atresia with ventricular septal defect. A bilateral ductus was present in 5 cases (20.8%), 3 with confluent and 2 with nonconfluent pulmonary arteries. One patient presented multiple systemic collaterals to the lungs. All the other patients had normal arborization of the pulmonary arteries. Seven patients presented an obstructed total anomalous pulmonary venous connection: 4 in inferior vena cava and 3 in superior vena cava. These anatomical observations provide useful information for the surgical palliation of these anomalies and, probably, warrant pre-operative angiographic evaluation in all the patients with right atrial isomerism.

Abstract
The muscular ventricular septal defect associated with the atrioventricular canal is a malformation which has not yet been extensively studied. Between June 1982 and December 1989, 151 patients with atrioventricular canal underwent echocardiography and angiocardiography in our Department. Of these 95 (62.9%) had a complete form and 56 (37.1%) a partial. Among the 151 patients, 81 (53.6%) presented Down syndrome. We found 5 muscular ventricular septal defects in 4 patients; in 3 cases there was a single defect and in one case two defects. These defects were midmuscular in all patients and one patient also presented an apical defect. All 4 patients with muscular ventricular septal defect presented a complete atrioventricular canal and aortic coarctation; 3 out of 4 patients had a hypoplastic left ventricle with absence of Down syndrome. The muscular ventricular septal defect is a malformation which is rarely associated with atrioventricular canal (4/151 = 2.6%). In our experience, it was always associated with a complete form with aortic coarctation and was very rare in Down syndrome patients (1/81 = 1.2%). These findings may represent a peculiar association of anomalies which may be caused by fetal hemodynamic mechanisms.
