Savelli aus dem Archaologischen M»seum in Zagreb publiziert, zahlt der Verfasser in seiner Studie noch einige Medaillen desselben Autors in kroatischen Museen und Galerien auf. Neben der Biographie und Interpretation der stilistischen Ausdrucksweise von S. Savelli bringt der Autor auch einen ausfuhrlichen Katalog aller seiner bekannten und bis heute erhaltenen Medailleurarbeiten.In this paper the author discusses one of the 200-odd medals of the Italian Renaissance kept in the Department of Coins and Medals of the Archeological Museum in Zagreb. It is the rare medal of the Venetian dodge Agostino Barbarigo (born 1419, dodge 1486, abdicated 1501), by Sperandio Savelli (born c. 1425, died 1504) with the bust of Barbarigo three quarters to the right , with a long beard, wearing the ducal cap and mantle, on the obverse. The legend is: (rose) AVGVSTINVS BARBADICVS VENETORVM DVX On the reverse one can see the doge in cap and robes, kneeling right and holding a banner with the lion of St. Mark; before him is the Lion of St. Mark, standing, left, nimbate, holding a book with his right forepaw. Both are on a rocky ground. Both the obverse and the reverse show a plain border. The legend on the reverse is: (leaf)OPVS(leaf)/ SPERA/NDEI , in exergue, (Armand I, 75, 46; Hill. p. 103, 401, P1.75; Hall 66). This medal was cast during Sperandio s year spent in Mantua (1495 — 1496) to commemorate the victory over the French and their king Charles VIII at Fornovo on 6th June 1495. Except for a few scratches and a hole, it is well preserved. It entered the Zagreb Collection in 1894 as a gift of Dr. Gjuro Catti of Rijeka. There are three more medals by Sperandio Savelli in museums of Croatia: the portrait of Andrea Barbazzo (Armand I, 64, 4; Hill 384) at the Town Museum in Split , the medal od Giovanni Bentivoglio II (Armand I , 65, 7; Hill 355) at the Museum of Applied Arts in Zagreb and a battered specimen of the Federigo Montefeltro medal (Armand I , 71, 29; Hill 389) at the Museum of the Požega Valley at Slavonska Požega
Mineral chemistry of the calcalkaline lavas from Marsili Seamount (southeast Tyrrhenian Sea): some magmatological and geodynamic considerations
No full textMineral chemistry data from lavas recovered over a large depth interval of the deep-water volcano of Marsili (Aeolian back-arc, SE Tyrrhenian Sea) are presented. The volcano is built up by products of calcalkaline affinity with the only exception of one outcrop of sub-alkaline, within plate basalts in the crestal area. On the whole, the calcalkaline lavas of Marsili have bimodal composition, and consist of basalts and andesites with, respectively, calcalkaline and high-K serial affinity. The andesites mark a change in the geodynamic conditions that is reflected by the clockwise rotation of the seamount rifting from the early NNE-SSE orientation, associated with the extrusion of the basalts, to a dominant tensional regime trending almost NE-SW. This evolution is discussed in the context of some magmatic-structural features in the southest Tyrrhenian volcanic area. -from Author

No full textFetal MRI of the cardiovascular system: role of steady-state free precession sequences for the evaluation of normal and pathological appearances
No full textPurpose. This study aimed to evaluate the feasibility of fetal magnetic resonance imaging (MRI) with steady-state free precession (SSFP) sequences to visualise the normal and pathological appearances of the cardiovascular system. Materials and methods. This is a prospective observational study of 83 pregnant women who underwent fetal cardiac MRI: 43 patients (cases) had echocardiographic suspicion of congenital heart disease; 40 patients (controls) did not. Fetal cardiac MRI consisted of a static phase with multiplanar SSFP sequences and a dynamic phase with real-time SSFP sequences. Two radiologists evaluated the diagnostic quality of the SSFP images in both the controls and cases, the MRI morphological and functional features in the controls and the MRI signs of congenital heart disease in the cases. Results. In both groups, SSFP sequences produced good-quality MR images and good visualisation of morphological features. Functional data appeared to be unavailable due to the current small temporal resolution and the technical impossibility of fetal cardiac triggering. MRI detected direct signs of congenital heart disease in 21 fetuses, indirect signs in six and both signs in 15. Conclusions. SSFP sequences are effective in demonstrating the morphological features of the cardiovascular system, whereas dynamic SSFP cine-MRI sequences may provide adjunctive albeit suboptimal functional information

Assessment of congenital heart disease (CHD): Is there a role for fetal magnetic resonance imaging (MRI)?
No full textPurpose: To review our experience with fetal magnetic resonance imaging (MRI) to evaluate congenital heart disease (CHD). Methods: We performed fetal MRI in 32 fetuses with an echocardiographically assessed CHD. Both direct and indirect signs of CHD were investigated. Direct signs considered were: morpho-volumetric abnormalities of the heart; malrotations; ventricular and atrial septal defects; anomalies of the origin, size and course of the great arteries. Indirect signs considered were: difficulty to recognize a "normal" anatomical structures in the reference projections; increase of the vascular size before a stenosis; hypertrophy of the papillary muscles; cardiomegaly and pericardial effusion. All MRI findings were compared with postnatal or autoptic findings. Results: MRI allowed the CHD to be visualised by direct signs in 17 fetuses, indirect signs in 5 and both direct and indirect signs in 9 fetuses, excluding the prenatal echocardiographic suspect of hypoplastic left heart syndrome in I fetus. Postnatal echocardiograms or autoptic findings confirmed a normal heart in I fetus and CHD in 31 fetuses including a single cardiac anomaly or syndrome in 19 fetuses, 2 associated cardiac abnormalities in I I and 3 cardiac anomalies in I fetus. However, in 2 fetuses MRI detected a ventricular septal defect successively disclosed by gold standard. Conclusions: MRI is a promising method for further assessment of the cardiovascular pathologies diagnosed by echocardiography, and may be a valuable tool in assessing associated extracardiac anomalies.

Robotic versus laparoscopic gastrectomy for gastric cancer: protocol for umbrella review of systematic reviews and meta-analyses
No full textLaparoscopic surgery has been adopted in some parts of the world as an innovative approach to the resection of gastric cancers. However, in the modern era of surgical oncology, to overcome intrinsic limitations of the traditional laparoscopy, the robotic approach is advocated as able to facilitate the lymph node dissection and complex reconstruction after gastrectomy, to assure oncologic safety also in advanced gastric cancer patients. Previous meta-analyses highlighted a lower complication rate as well as bleeding in the robotic approach group when compared with the laparoscopic one. This potential benefit must be balanced against an increased time of intervention. The aim of this umbrella review is to provide a comprehensive overview of the literature for surgeons and policymakers in order to evaluate the potential benefits and harms of robotic gastrectomy (RG) compared with the laparoscopic approach for gastric cancer.

POTENTIAL ROLE OF FETAL CARDIAC EVALUATION WITH MAGNETIC RESONANCE IMAGING: PRELIMINARY EXPERIENCE.
No full textOBJECTIVE: To report our experience with magnetic resonance imaging (MRI) in fetal heart evaluation. METHOD: Two radiologists examined 31 MRI of fetuses with no ultrasound (US) evidence of cardio-thoracic anomalies. T2-weighted half-Fourier single-shot turbo spin-echo sequences were acquired for anatomic evaluation; fast imaging with steady-state free precession (TrueFISP) and cine-MR sequences with real-time steady-state free precession oriented like standard fetal echocardiographic projections were acquired for the characterization of cardiovascular morphology and function. RESULTS: In every case, MRI assessed the viscero-atrial situs. The four-chamber view and the short-axis view of the left ventricle were obtained in all fetuses, the long-axis view of the aortic arch in 28, the long-axis view of the ductus arteriosus in 17, the five-chamber view in 12, the long-axis of the left ventricle in 9, the three-vessel view in 7, the tricuspid-aortic view in 3, and the transverse view of the aortic arch and the angulated view of the arch and the ductus arteriosus simultaneously in 2 fetuses. CONCLUSION: Our preliminary experience demonstrates the feasibility to visualize the fetal heart with routine fetal MRI protocols in particular, by means of acquisition of TrueFISP imaging (morphological study) and real-time cine-MRI (dynamic study), potentially making MRI a second-level tool to add to fetal echocardiography in the prenatal study of congenital cardiac malformations
