Abstract: The de-excitation of medium mass nuclei 118,134Ba produced in fusion process of 78,86Kr on 40,48Ca targets at 10 AMeV is studied, in order to investigate the isospin dependence of the decay modes; the neutron enrichment of the compound nuclei is in fact expected to play an important role on the emission mechanisms, providing crucial information on fundamental nuclear quantities such as level density, fission barrier, viscosity and symmetry energy. The experiment was performed at INFN-LNS with the 4π multidetector for charged particles CHIMERA, used for the first time in this low energy regime, thanks to a suitable Pulse Shape Discrimination method for charge identification applied to the silicon detectors. Preliminary results show a different isotopic composition and relative enrichment for the same Z in the two systems. The yields of the Intermediate Mass Fragments (IMF, 3

Abstract: A quantitative comparison is made between the absolute cross sections associated with statistical and dynamical emission of heavy fragments in the 124Sn+64Ni and 112Sn+58Ni collisions experimentally investigated at 35A MeV beam energy using the multidetector CHIMERA. The result shows that the dynamical process is about twice as probable in the neutron-rich 124Sn+64Ni system as in the 112Sn+58Ni neutron-poor one. This unexpected and significant difference indicates that the reaction mechanism is strongly dependent on the entrance-channel isospin (N/Z) content.

356. Strutture sintattiche, semantico-metaforiche e pragmatiche nei resoconti di immigrazione in inglese pidgin e creolo africano: malintesi interpretativi ed equivoci traduttivi

Abstract: Le incomprensioni nella comunicazione interculturale attraverso una ‘lingua franca’ come l’inglese sono principalmente dovute a modi differenti attraverso cui le diverse culture concettualizzano gli eventi, li testualizzano nelle rispettive lingue native e, quindi, trasferiscono tali concettualizzazioni e testualizzazioni nelle strutture della ‘lingua franca’. Le conseguenze di questi ‘trasferimenti’ concettuali e testuali, o transfers, possono spesso essere drammatiche, soprattutto in colloqui istituzionali mirati a valutare i diritti dei migranti privi di documenti nei Paesi Occidentali. Ma cosa rende possibile l’incomprensione in simili situazioni? Per rispondere a questa domanda, il presente studio intende investigare alcuni motivi cruciali che determinano i malintesi in contesti di comunicazione istituzionale con migranti attraverso la lingua franca inglese. L’interesse è pertanto incentrato sul concetto di ‘lingua franca’ come una lingua ‘dislocata’ (displaced) – vale a dire, collocata al di fuori del proprio contesto sociale e geografico – e ‘transidiomatica’ – cioè, scollegata da una specifica comunità linguistica. Infatti, una ‘lingua franca’, come l’inglese, codifica strutture semantiche, sintattiche, pragmatiche e socio-culturali che derivano dalle lingue native dei migranti sottoposti a colloqui e interrogatori istituzionali (cfr. Nigerian Pidgin English e Sierra Leone Krio). Tuttavia, i mediatori/interpeti interlinguistici e interculturali (europei) che gestiscono questo genere di situazioni comunicative spesso decodificano le strutture linguistiche dei migranti secondo i propri parametri linguistici e socio-culturali nativi. I malintesi che ne derivano possono pertanto causare problemi sociali e politici con conseguenze molto serie per coloro che richiedono l’asilo o un permesso di soggiorno.

Subjects: interpretazione, Letteratura Inglese, Walter Pater
Abstract: Questo studio esplora la lettura pateriana della Monna Lisa nel saggio dedicato a Leonardo da Vinci, inserito nella raccolta The Renaissance (1873), indagandone la relazione con alcuni contesti, in particolare i commenti di Ruskin su Leonardo, la critica di Anna Jameson in Memoirs of Early Italian Painters (1845). L’influenza della lettura pateriana nella cultura novecentesca viene inoltre rimarcata attraverso un’analisi dell’interpretazione del dipinto fornita da Freud nel saggio Un ricordo d’infanzia di Leonardo da Vinci (1910).

Abstract: International audience; For fragments emitted in the reactions 124Sn + 64Ni and 112Sn + 58Ni at 35 AMeV, isotopic composition and velocity correlations have been studied as a function of the centrality of the collision, using the 4\pi Chimera multidetector. We have investigated the time scale for fragments formation, in order to distinguish between prompt dynamical and sequential statistical emission. Promptly emitted light fragments (Z \leq 9) produced in the mid-rapidity domain are characterised by larger N/Z ratio and stronger angular anisotropies than those produced in sequential statistical emission. Results are compared with stochastic BNV code simulations obtained for primary fragments. Valuable information on the symmetry term of the nuclear equation of state at sub-saturation densities are obtained.

Abstract: Signatures of isospin effects were investigated for neutron-rich (124Sn+64Ni) and neutron-poor (112Sn+58Ni) systems at 35 MeV/nucleon for noncentral collisions. The centrality dependence of these signatures was tested for several impact parameter estimators. Our main observations are (i) the yields of 1H and 3He particles in the neutron-poor system are strongly enhanced with respect to the neutron-rich system, and the yields of 3H, 6He, and 7,8Li are suppressed at all impact parameters, (ii) the yields of 2H, 4He, and 6Li particles are almost the same for both systems, (iii) the N/Z ratio of intermediate mass fragments is correlated with the neutron richness of the system and is weakly dependent on the centrality of the collision, and (iv) the neutron richness of the detected fragments increases strongly with decreasing rapidity in the range from that of the projectile-like fragment to the c.m. region. The gross features of experimental data are reproduced by quantum molecular dynamics model calculations. A comparison between model calculations and the data indicates that the fragments produced in the c.m. regions are weakly excited.

Abstract: Some properties of fast, nonequilibrium splitting of projectiles in the 124Sn+64Ni reaction at 35AMeV were determined using the 4π CHIMERA detector system. In particular the charge distributions, in- and out-of-plane angular distributions, and relative velocities of projectilelike fragments were measured. The time scale of the processwas estimated and it turned out that the process is sequential but much faster than the ordinary, equilibrated fission.

365. Gli opposti che convergono: Amleto e Don Chisciotte nell'opera di I.S. Turgenev

Author: POLITI, Gloria, G. Politi, and Politi, Gloria
Abstract: Il discorso di I.S. Turgenev sugli Amleto e i Don Chisciotte è la quintessenza del genio turgeneviano. Come nei romanzi e nei racconti, il germe di una storia non è stata mai per il romanziere questione di trama, bensì la rappresentazione di alcuni tipi: anche qui Amleto incarna l'uomo superfluo della generazione precedente e Don Chisciotte Il modello dei rivoluzionari degli anni Cinquanta.

Author: POLITI, Gloria, G. Politi, and Politi, Gloria
Abstract: Nel discorso, Turgenev fornisce una sorta di dossier particolareggiato sui due personaggi oggetto d'analisi, senza mai scadere nella rappresentazione di quadri stantii di eroi letterari ma nella volontà dichiarata di raffigurare esseri viventi, palpitanti, immersi nel flusso della realtà quotidiana, esseri che lottano sì contro i mulini a vento o si macerano nei dubbi esistenziali ma che sono facilmente riconoscibili in qualsiasi tempo e in qualsiasi luogo.

371. Psychological factors in functional hypothalamic amenorrhea: A systematic review and meta-analysis.

Author: Bonazza F, Politi G, Leone D, Vegni E, and Borghi L
Subjects: Female, Humans, Thinness complications, Attitude, Amenorrhea etiology, Hypothalamic Diseases complications
Abstract: Background: Psychological factors have been found to be associated with functional hypothalamic amenorrhea (FHA); however, their role in the onset or persistence of FHA is still understudied. The study aims to assess the associations of psychological factors with the presence vs the absence of FHA., Methods: A systematic literature search has been conducted across the major databases (PubMed, PsycINFO, Scopus, and Embase) to explore the psychological factors associated with FHA. The search was limited to English-written articles published from 2000 onwards. Articles were selected based on stringent inclusion/exclusion criteria. After data extraction, meta-analysis and meta-synthesis were conducted., Results: Of 349 retrieved articles, eight studies were included. Findings indicate that the main psychological factors associated to FHA seem to be depression and eating attitudes, especially drive for thinness. FHA women present higher levels of anxiety, sleep disorders, dysfunctional attitudes, and alexithymia. The meta-analysis on drive for thinness revealed that the pooled MD across the studies was statistically significant both in the fixed 0.63 (95% CI: 0.31-0.95) and random model 0.70 (95% CI: 0.13-1.26). Likewise, as for depression, the pooled MD across the studies was statistically significant both in the fixed 0.60 (95% CI: 0.36-0.84) and random model 0.61 (95% CI: 0.20-1.01)., Discussion: Findings showed the association of psychological factors and FHA and recognized their involvement in the persistence of the disorder. A multidisciplinary approach should involve a collaborative process between gynecologists, clinical psychologists, and psychiatrists, from diagnosis to treatment. Longitudinal studies should be implemented with a comparison/control group or by including clinical psychologists in the psychological assessment and study design., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Bonazza, Politi, Leone, Vegni and Borghi.)

372. IoT-Based Microclimate and Vibration Monitoring of a Painted Canvas on a Wooden Support in the Monastero of Santa Caterina (Palermo, Italy).

Author: Trigona C, Costa E, Politi G, and Gueli AM
Subjects: Humidity, Temperature, Vibration, Environmental Monitoring, Microclimate
Abstract: The main objective of this work is the characterization and observation of the performance of an IoT measurement and monitoring system in the field of cultural heritage conservation for assessing the health condition of artworks. This article also describes the application of this system to the monitoring of a canvas painting applied on a wooden support, an artwork from the 19th century by the painter Giuseppe Patricolo depicting The Deposition , placed inside a niche in the Santa Caterina Monastery in Palermo (Italy). Considering the presence of the wooden structure, it is useful to measure not only microclimatic parameters such as temperature and humidity, but also vibrations that can in fact cause degradation phenomena in these artworks. This is a first step towards the development of mimetic systems integrated in the work of art without causing physical, mechanical or chemical alterations and ensuring that the level of microclimatic parameters is below the threshold values whose exceeding could compromise the entire artefact.

Abstract: Objectives: The aims of this study were to investigate the feasibility of coronary ostia cannulation after transcatheter aortic valve replacement (TAVR) and to assess potential predictors of coronary access impairment., Background: Certain data concerning the feasibility and reproducibility of coronary cannulation after TAVR are lacking., Methods: RE-ACCESS (Reobtain Coronary Ostia Cannulation Beyond Transcatheter Aortic Valve Stent) was an investigator-driven, single-center, prospective, registry-based study that enrolled consecutive patients undergoing TAVR using all commercially available devices. All patients underwent coronary angiography before and after TAVR. The primary endpoint was the rate of unsuccessful coronary ostia cannulation after TAVR. Secondary endpoints were the identification of factors associated with the inability to selectively cannulate coronary ostia after TAVR., Results: Among 300 patients enrolled in the RE-ACCESS study from December 2018 to January 2020, a total of 23 cases (7.7%) of unsuccessful coronary cannulation after TAVR were documented. This issue occurred in 22 of 23 cases with the use of Evolut R/PRO transcatheter aortic valves (TAVs) (17.9% vs. 0.4%; p < 0.01). In multivariate analysis, the use of Evolut R/PRO TAVs (odds ratio [OR]: 29.6; 95% confidence interval [CI]: 2.6 to 335.0; p < 0.01), the TAV-sinus of Valsalva relation (OR: 1.1 per 1-mm increase; 95% CI: 1.0 to 1.2; p < 0.01), and the mean TAV implantation depth (OR: 1.7 per 1-mm decrease; 95% CI: 1.3 to 2.3; p < 0.01) were found to be independent predictors of unsuccessful coronary cannulation after TAVR. A model combining these factors was demonstrated to predict with very high accuracy the risk for unsuccessful coronary cannulation after TAVR (area under the curve: 0.94; p < 0.01)., Conclusions: Unsuccessful coronary cannulation following TAVR was observed in 7.7% of patients and occurred almost exclusively in those receiving Evolut TAVs. The combination of Evolut TAV, a higher TAV-sinus of Valsalva relation, and implantation depth predicts with high accuracy the risk for unsuccessful coronary cannulation after TAVR.

Abstract: Purpose: This study was undertaken to prospectively determine the diagnostic capabilities of magnetic resonance (MR) imaging in detecting myometrial and cervical invasion and lymph node involvement in endometrial carcinoma and to identify the causes of errors in staging endometrial carcinoma., Materials and Methods: Twenty consecutive patients with a histological diagnosis of endometrial carcinoma underwent preoperative MR imaging. MR findings were compared with surgical staging, considered as the standard of reference., Results: In assessing myometrial invasion, MR imaging showed 70% accuracy, 80% sensitivity, 40% specificity, 80% positive predictive value (PPV), and 40% negative predictive value (NPV). In detecting cervical invasion, MR imaging had 95% accuracy, 100% sensitivity, 94.4% specificity, 66.7% PPV, and 100% NPV. In evaluating lymph node involvement, MR imaging showed 100% accuracy, sensitivity, specificity, PPV and NPV. Errors in evaluating myometrial invasion were caused by polypoid tumour, adenomyosis and leiomyomas, whereas those in evaluating cervical invasion were caused by dilatation and curettage., Conclusions: MR imaging is a reliable technique for preoperative evaluation of endometrial carcinoma. Its main limitation is differentiating between stage IA and IB carcinomas, which is not highly important for surgical planning. Cooperation between the gynaecologist and radiologist is mandatory to avoid staging errors.

Abstract: Purpose: This study prospectively compared the diagnostic capabilities of magnetic resonance (MR) imaging with conventional defecography (CD) in outlet obstruction syndrome., Materials and Methods: Nineteen consecutive patients with clinical symptoms of outlet obstruction underwent pelvic MR examination. The MR imaging protocol included static T2-weighted fast spin-echo (FSE) images in the sagittal, axial and coronal planes; dynamic midsagittal T2-weighted single-shot (SS)-FSE and fast imaging employing steady-state acquisition (FIESTA) cine images during contraction, rest, straining and defecation. MR images (including and then excluding the evacuation phase) were compared with CD, which is considered the reference standard., Results: Comparison between CD and MR with evacuation phase (MRWEP) showed no significant differences in sphincter hypotonia, dyssynergia, rectocele or rectal prolapse and significant differences in descending perineum. Comparison between CD and MR without evacuation phase (MRWOEP) showed no significant differences in sphincter hypotonia, dyssynergia or enterocele but significant differences in rectocele, rectal prolapse and descending perineum. Comparison between MRWEP and MRWOEP showed no significant differences in sphincter hypotonia, dyssynergia, enterocele or descending perineum but significant differences in rectocele, rectal prolapse, peritoneocele, cervical cystoptosis and hysteroptosis., Conclusions: MR imaging provides morphological and functional study of pelvic floor structures and may offer an imaging tool complementary to CD in multicompartment evaluation of the pelvis. An evacuation phase is mandatory.

Abstract: 40Ca+;{40,48}Ca,46Ti reactions at 25 MeV/nucleon have been studied using the 4pi CHIMERA detector. An isospin effect on the competition between fusionlike and binarylike reaction mechanisms has been observed. The probability of producing a heavy residue is lower in the case of N approximately Z colliding systems as compared to the case of reactions induced on the neutron rich 48Ca target. Predictions based on constrained molecular dynamics II calculations show that the competition between fusionlike and binary reactions in the selected centrality bins can constrain the parametrization of the symmetry energy and its density dependence in the nuclear equation of state.

Abstract: To verify the hypothesis of an early impairment of erythropoietin (Epo) production and to assess the adequacy of its circulating levels in diabetic nephropathy, we investigated Epo values in 18 microalbuminuric type 2 diabetic patients with normal renal function (7 anaemic and 11 nonanaemic), 24 subjects with uncomplicated iron-deficiency anaemia, and 15 healthy controls comparable for sex and age. Mean+/-S.D. plasma Epo level was 56.4+/-12.7 mU/mL in iron-deficient patients and 9.3+/-2.6 mU/mL in controls. In diabetic groups, mean+/-S.D. Epo level was 11.38+/-3.65 mU/mL in nonanaemic and 49.12+/-6.44 mU/mL in anaemic subjects. No significant difference (P>.05) in Epo values was found between controls and nonanaemic diabetic patients. Anaemic diabetics and iron-deficient subjects had significantly higher values than the nonanaemic groups (P>.001). An inverse significant relation between Epo levels and Hb concentration resulted in both anaemic diabetics (r=-.44, P>.05) and iron-deficient patients (r=-.61, P=.001). Analysis of covariance (P>.05) and comparison of the two regression lines (t=0.4, df=29, P>.05) did not show any significant difference between diabetic patients with anaemia and iron-deficient patients. These results suggest that normochromic anaemia observed in microalbuminuric diabetic patients with normal renal function is not due to Epo deficiency, and circulating levels of this hormone are suitably increased with regard to Hb concentration.

Abstract: Objective: To evaluate and compare the long-term efficacy and safety of two different beta-interferon preparations (IFN-beta-1a vs IFN-beta-1b)., Materials and Methods: Two parallel outpatient groups with relapsing-remitting multiple sclerosis (RRMS), according to Poser criteria, were treated with either intramuscular IFN-beta-1a 30 microg (group A, n = 62) or subcutaneous IFN-beta-1b 250 microg (group B, n = 64)., Results: A statistically significant reduction was seen in the relapse rate (P < 0.0001) in both groups. No significant difference was found between the two groups (P = 0.43). After 6 years of therapy, the mean Expanded Disability Status Scale score was 3.22 +/- 1.47 (delta 1.03 +/- 1.35) in group A and 3.34 +/- 1.47 (delta 0.97 +/- 1.47) in group B (P = 0.47)., Conclusions: Our study results suggest that the efficacy of IFN-beta-1a 30 microg once weekly and SC IFN-beta-1b 250 microg every other day is similar. Both IFN-beta-1a and IFN-beta-1b are effective in slowing disability progression.

Abstract: The aim of the present study was to evaluate the efficacy of the combination of cyclophosphamide (CTX) and interferon beta (IFN beta) in a group of relapsing remitting (RR) multiple sclerosis (MS) patients who experienced treatment failure during IFN beta therapy. It is the general experience that immunomodulatory agents (IMA) are only partially effective in RR patients. Recent data on the efficacy of immunosuppressive therapies for these patients are encouraging. The anti-inflammatory and immunosuppressive effects of CTX have been utilized to treat selected cases of multiple sclerosis with a progressive and worsening course as rescue therapy. Thirty RR MS patients with clinically defined MS who experienced treatment failure during IFN beta therapy (2 or more relapses per year or 1.5 EDSS point worsening in one year) were enrolled in the study and treated with CTX iv pulse therapy added to IFN beta and followed up for 24 months. As primary endpoints we evaluated the yearly relapse rate. We also evaluated the percentage of patients free of relapses and of EDSS variations. We analysed the results at one year before entry (T0: IFN beta alone), 12 (T1) and 24 (T2) months after entry. Brain MRI was performed at T0, at T1 and T2. The 30 RR patients who had experienced a high number of relapses (rr =1.4) at T0 showed a significant improvement in yearly relapse rate (rr = 0.4) at T1 and a further improvement (rr = 0.17) at T2 (p < 0.001). The percentage of patients free of relapse was 70% at T2 (p < 0.0001). EDSS score changed from 2.6+/-1.23 at T0 to 2.2 +/- 1.5 at T2, showing only a trend of improvement. No significant variation of MRI lesion load and no severe adverse events were recorded during the study. These data showed that the combination of CTX plus IFN beta halted the progression of disease in active and deteriorating MS patients suggesting the necessity of RCTs to test the efficacy of this combination therapy in active RRMS patients or in patients who experienced treatment failure in response to disease modifying drugs (DMDs).

Abstract: Aim: In the inflammatory state, intercellular adhesion molecule-1 (ICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) play a key role in promoting migration of immunological cells from the circulation to target site. Aim of our study was to investigate soluble forms of these molecules in patients with virus-related chronic liver diseases, to assess their behavior in different pathologies and correlation with severity of liver damage., Methods: Circulating ICAM-1 and VCAM-1 were assayed by EIA commercial kits (R and D System Co., Abington, UK) in 23 patients with chronic active hepatitis (CH), 50 subjects affected by liver cirrhosis (LC) and 15 healthy controls comparable for sex and age. In patients, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also detected by autoanalyzer., Results: LC patients had significantly higher ICAM-1 values than CH patients (38.56+/-7.4 ng/mL vs 20.89+/-6.42 ng/mL; P < 0.001) and these ones had significantly higher values than controls (12.92+/-1.08 ng/mL; P < 0.001). In CH group, ICAM-1 levels were significantly related to inflammatory activity (P = 0.041) and ALT values (r = 0.77; P < 0.05). VCAM-1 values were significantly increased only in LC patients (P < 0.001) and related to severity of liver impairment., Conclusion: These findings suggest that the determination of serum ICAM-1 can be considered as an additional useful marker of hepatocellular necrosis and inflammatory activity in chronic hepatitis, while serum VCAM-1 is an indicator of liver fibrogenesis and severity of disease in cirrhosis.

Abstract: Aim: The aim of our study was to investigate circulating levels of intercellular adhesion molecule-1 (sICAM-1) and vascular cellular adhesion molecule-1 (sVCAM-1) in cirrhotic patients, with and without chronic anaemia, to establish whether there was a relationship between inflammatory activity and anaemia., Methods: We investigated 14 anaemic (mean hemoglobin value 10.65+/-1.06 g/dL) and 14 non anaemic (mean hemoglobin value 13.8+/-0.89 g/dL) subjects affected by virus C-related liver cirrhosis comparable for sex, age and degree of liver dysfunction such as expressed by Child-Pugh classification. Circulating sICAM-1 and sVCAM-1 were measured by EIA commercial kit (R&D System Co, Abington, UK) and mean+/- standard deviation values in two groups were compared by t-test and Kruskall-Wallis test., Results: Mean+/-standard deviation sICAM-1 was 35.06+/-4.06 ng/mL in anaemic and 23.39+/- 6.1 ng/mL in non anaemic cirrhotic patients. Mean+/-standard deviation sVCAM-1 was 47.66+/-8.18 ng/mL in anaemic 31.77+/-6.08 ng/mL in non anaemic patients, respectively. Statistical analysis showed a significant difference between the two groups both in sICAM-1 (p=0.01) and sVCAM-1 (p=0.03) values., Conclusions: Our study show that chronic anaemia, in liver cirrhosis, is associated to a greater increase of circulating adhesion molecules and suggests that inflammation may contribute to persistence of anaemic state, worsening the outcome of cirrhotic patients.

Abstract: Cyclophosphamide (CTX) is an alkylating agent related to nitrogen mustards whose anti-inflammatory and immunosuppressive effects have been utilised to treat selected cases of multiple sclerosis with a progressive and worsening course. To halt the progression of disease in patients refractory to disease modifying drugs CTX has been given, and several open-label studies have recently shown clinical benefits. In a previous study we demonstrated the effectiveness of a combination of IV monthly pulses of CTX and interferon beta (IFN-beta) in 10 patients with "rapidly transitional" form of multiple sclerosis characterised by severe and frequent attacks and rapid progression of disability. The present study reports the clinical and MRI follow-up 36 months after the discontinuation of CTX showing the maintenance of the results obtained in relapse rate (p<0.001), EDSS (p<0.001), T2 MRI total lesion load (p<0.001) and T2 lesions number (p<0.001) compared to the pre-treatment period. These encouraging findings and the absence of significant recorded side effects affirm that the association of CTX plus interferon-beta is amenable, safe and can be recommended in rapidly worsening MS patients.

Abstract: Introduction: The aim of this study is to assess the accuracy of a new US examination: 'voiding color Doppler US ' in the early diagnosis and staging of vesico-ureteral reflux (VUR). The contrast agent US was SH U 508A (Levovist, Schering, Berlin), which produces a chromatic accentuation of the signals picked up by the color Doppler US. Eighteen patients (10 females, eight males) were recruited for the study. In two patients a second examination was performed for follow-up after a VUR conservative therapy. All patients were taken under examination for the evaluation of possible VUR. In all patients the voiding color Doppler US was followed by voiding cystourethrography (VCUG) and the data obtained were compared., Materials and Methods: A total of 18 patients aged between 3 months and 10 years, were recruited for the study. The results of the examination were the following: urinary tract infections, follow-up of VUR after conservative or surgical therapy, miscellaneous indications. Voiding color Doppler US was performed, followed by a VCUG. The voiding color Doppler US consists in the trans-catheter introduction of a contrast agent SHU 508 A (Levovist, Schering, Ag. Berlin) into the bladder and a subsequent test with the color Doppler US to show or exclude the presence of reflux into the ureters and/or into the pyelo-caliceal cavity of the kidneys. After the introduction of the contrast agent US the ultrasound scanning of the bladder, the ureters and the pyelo-caliceal cavity was performed to examine the reflux degree. The ultrasonographic investigations were perfomed with AU 590 asyncronus US (Esaote Biomedica, Genova) with a 3.5 MHz convex probe., Results: After the trans-catheter introduction of the contrast agent US, vesico-ureteral reflux occured in 13 patients (77.2%). The reflux degree was also measured by means of ultrasound and was later confirmed by VCUG. The mean times of each examination were as follows: initial US, 10 min; catheterization, 8 min; voiding color Doppler US, 15 min; overall VCURG examination 10 min. The overall mean duration of the voiding color Doppler US examination was 33 min. The comparable mean time for VCUG, including the catheterization time, was 20 min. No reactions of intolerance to the ultrasound contrast agent occurred., Discussion and Conclusions: The voiding color Doppler US test has evidenced in all patients the presence of the contrast agent US in the bladder after the introduction. In 13 patients (77.2%) with presence of VUR, the voiding color Doppler US test has established the reflux degree confirmed by cystourethrography. The superimposability of the data obtained with voiding color Doppler US and VCUG would seem to confirm the importance of this new ultrasonographic technique in the diagnosis and staging of VUR.

Abstract: Purpose: We investigated the accuracy of a new US investigation technique, called retrograde cystography US, in the early diagnosis and staging of vesicoureteral reflux., Material and Methods: We examined 5 patients, aged 3 months to 10 years, suffering from hydronephrosis and/or pyelonephritis. Retrograde cystography US was followed by conventional retrograde cystography. Retrograde cystography US consists in the transcatheter introduction of a contrast agent (Levovist, Schering AG, Berlin, Germany) into the bladder and a subsequent color Doppler examination to show or exclude the presence of reflux. Superpubic scanning of bladder, ureters and pyelocaliceal cavity was performed after echocontrast agent introduction to assess the reflux grade. US was performed with an Esaote AU 590 asynchronous scanner (Esaote Biomedica, Genova, Italy) with a 3.5 MHz convex probe., Results: After the transcatheter introduction of Levovist, vesicoureteral reflux was seen in 5/5 patients. Reflux grade was also measured with US and then confirmed at retrograde cystography. In a patient with pyelonephritis and no reflux at follow-up cystography, retrograde cystography US identified a unilateral reflux (grade 1)., Discussion and Conclusions: Retrograde cystography US showed the echocontrast agent in the urinary tract and assessed the reflux grade in all 5 patients, which was then confirmed at cystography. In a patient with grade 1 unilateral reflux at cystography US, follow-up conventional cystography showed no reflux, which seems to confirm a higher sensitivity of the US technique. The total agreement of conventional and US findings seems to confirm the importance of the US method for the diagnosis and staging of vesicoureteral reflux.

Abstract: Introduction: The differential diagnosis of focal hepatic lesions is still studied by diagnostic imaging operators. A big step forward in the field of ultrasound (US) has come from the color Doppler mode permitting accurate studies of the vascularization of focal hepatic lesions. Echocontrast agents have further improved color Doppler sensitivity to slow flows and have permitted to visualize intralesional vascular signals which were missed at B-mode US. New data have thus been acquired which can be integrated with flowmetric findings to help make the correct differential diagnosis with a fair safety margin. We studied the pathognomonic US pattern for each type of lesion., Material and Methods: We examined 55 patients with single hepatic lesions which had already been typified: they were 10 hepatic angiomas, 3 focal nodular hyperplasias (FNH), 2 hepatic adenomas, 20 hepatocarcinomas and 20 hepatic metastases. Color Doppler investigations were performed on each patient before and after the intravenous (i.v.) administration of an echocontrast agent (Levovist, Schering AG, Berlin, Germany). For each lesion we studied the morphological characteristics, the resistance index (RI) of intralesional arterial vessels, the hepatic perfusion index and the maximum speed in intralesional vessels., Results: Contrast-enhanced US showed no intralesional signals or afferent branches in 8 hepatic angiomas, which however exhibited some peripheral vascularization; weak intralesional vascular signals were demonstrated in 2 cavernous angiomas. Intralesional signals, as well as peripheral vascularization, were detected in the 3 FNH cases, which also exhibited a centripetal afferent branch; the hepatic perfusion index in these lesions never exceeded .25. The two hepatic adenomas had similar color flowmetry to FNH also after i.v. contrast agent administration, except for the contripetal afferent vessel which was not seen. In the 20 hepatocarcinomas, contrast-enhanced images showed numerous intralesional signals and afferent branches which, with the peripheral vascularization, resulted in a basket-like pattern. Flowmetry of intralesional arterial vessels showed an irregular systodiastolic range, with RI = .32 +/- .5 in 12 lesions and high in the remaining 8 lesions (RI = .82 +/- 10). The hepatic perfusion index was .65 +/- 10 in all patients. In 14 of the 20 hepatic metastases, B-mode US showed no intralesional signals except for 6 metastases from colorectal carcinoma, and contrast-enhanced findings were about the same. The hepatic perfusion index at flowmetry ranged .30 to .45 in all patients.

400. [Familial Marfan's syndrome. A critical review and presentation of a clinical case].

Subjects: Adolescent, Female, Humans, Prognosis, Marfan Syndrome complications, Marfan Syndrome diagnosis, Marfan Syndrome genetics
Abstract: Aim of this paper is to describe and discuss, on the basis of an exhaustive review of literature, the case of a 14-year-old girl with familiar Marfan's syndrome. This disease is a generalized inherited disorder with involvement of connective tissue and symptoms affecting ocular, skeletal and cardio-vascular systems, usually diagnosed in young age and associated with a poor prognosis because of late severe aortic complications (dissection, dilation or aneurysms, regurgitation, etc.). The young patient sought to our medical attention because of severe leanness, delayed menarca and irregular menstruations; physical examination disclosed the typical "morphotype of Marfan" with long limbs, slenderness of hands and feet, severe kyphoscoliosis, narrow chest with "pectus excavatum", marked hyperextensible joints, and high arched palate with malocclusion. Echocardiography demonstrated a mild mitral valve prolapse. The 43-year-old patient's mother presented an undiagnosed Marfan's syndrome, despite typical morphotype, muscle-skeletal alterations and moderate dilation of ascending aorta. The maternal grand-mother deceased prematurely for cardiopathy of unknown origin. It is stressed that the disease should not be underestimated, because the early diagnosis is important for the patient's prognosis, allowing the early preventive surgical intervention for correcting aortic or valvular alterations. The echocardiography represents a sensitive and noninvasive mean, useful to manage the patients with proven or suspected aortic dilation. The subjects with Marfan's syndrome who exhibit rapid progression of aortic dilation, or an aortic diameter in excess of 50 mm, should be considered for an elective surgical intervention (at low mortality and suitable to increase remarkably the lifetime expectation). Women with syndrome of Marfan should be advised on the high cardio-vascular risk during pregnancy.
