Intra Operative Radiation Therapy (IORT) is a technique based on delivery of a high dose of ionising radiation to the cancer tissue, after tumour ablation, during surgery, while reducing the exposure of normal surrounding tissue. The Novac7 is a new linear accelerator expressly conceived to perform in the operating room. This accelerator supplies electron beams with high dose rate. Because these peculiar characteristics, classical dosimetric techniques are not able to give at once a real-time response and an extensive measure of the absorbed dose. The new system is composed by a grid of scintillating optical fibres coupled with two arrays of photodiodes. The instrument samples the delivered beam at 100 Hz. The dedicated software collects the two projection-signals and reconstructs the bi-dimensional image. Moreover it provides a series of dosimetric parameters. We studied an appropriate reconstruction algorithm searching the best compromise between the computational complexity and an high precision. An accelerator having energies ranging from 3 to 12 MeV has been used for the tests. The system is able to give a real time response (within 30 seconds), the resolution is of 1 millimeter. The response is linear versus dose and the measures are not affected by the high dose rate. The conclusions confirm the capability of the instrument to overcome problems encountered with classic dosimetry, showing that the results obtained strongly encourage the continuation of this research. Index Terms--Digital system, dosimetry, electron beam, FOS, Intra Operative Radiation Therapy (IORT), photodiode array, real-time acquisition.

Synchrotron-based digital radiography and microtomography devices are powerful, nondestructive, high-resolution research tools. In this paper, we present a linear system with a pixel size of 22.5 [micro]m and a field-of-view (FOV) 13 cm long and about 1 mm high. The system is composed of a linear converter GOS screen coupled to an intensified electron-bombarded CCD (EBCCD) camera, by means of a rectangular-to-linear fiber optic adapter. This optical guide is composed of seven bundles, each one transporting light in a coherent way to preserve spatial information. In this way, a high spatial resolution over an extended FOV is obtained. The detector works as an X-ray scanner by means of a high-precision translation mechanical device with 18 cm travel range. The total FOV obtained this way is 13 cm long and 18 cm high. The aim of this paper is to demonstrate the feasibility of this system to investigate a large area of a bone and to calculate the appropriate histomorphometric parameters. Here we present an investigation gained at ELETTRA synchrotron facility at Trieste, Italy. A monochromatic 34-keV beam has been used for imaging a human proximal femur, about 9 cm in width, with our system. The reconstructed images (13 cm x 13 cm) were cross sections containing femoral head, femoral neck, and greater trochanter. The local variations in trabecular and cortical structure of the examined bone were clearly visible at a level not obtainable with medical CT scanners. The used spatial resolution allowed the visualization of thin trabeculae, which typically lie in a range of 100 [micro]m or lower. The quality of the reconstructed cross-section images confirmed that the system presented is a novel tool for high resolution three-dimensional (3-D) imaging of bone structure, with a pixel size over a volume of interest not achievable with conventional microCT scanners. Index Terms--Biomedical, X-ray detectors, X-ray tomography.

In recent years there has been a growing demand from museums for computed tomography (CT) diagnostic measurements to be performed on famous artworks (sculptures and paintings) inside the museum itself in order to assess whether are they in good condition or need a restoration procedure. The problem of radioprotection becomes critical when the energy used in CT is high, as typically occurs in the case of CT measurements on sculptures, where linacs are used to produce the high-energy X-rays necessary to penetrate marble or metal. In this study we used Monte Carlo simulations in order to evaluate dose distribution inside a museum where a high-energy CT system is used for diagnostic measurements on a sculpture.

- Abstract
Information and technology (IT) based tools are widely used in all phases of the disaster management cycle (DMC), improving the effectiveness of the prevision-prevention, preparedness, response, and recovery phases. The availability of on-field collected data provides an answer to the need to represent the scenario in which decision-makers will intervene. In this context, disaster management experience has shown that in many cases the users of on-field assessment outcomes (i.e., decision-makers) need: a data collection tool quickly and simply adaptable to better respond to specific and conditional needs; the automated elaboration of situation results; and the ability to exchange the information between the different phases of the DMC. This paper illustrates the IT tool, called "SPRINT-Engine", which was developed to meet these requirements. The SPRINT-Engine has been specifically developed and improved to permit easy and rapid customizability, even in near real-time. The paper presents some applications in real cases of on-field assessment managed by SPRINT-Lab researchers in support of institutions in various activities and projects at different scales and in different phases of the DMC., (© 2023.

- Abstract
X-ray Computed Tomography (CT), a commonly used technique in a wide variety of research fields, nowadays represents a unique and powerful procedure to discover, reveal and preserve a fundamental part of our patrimony: ancient handwritten documents. For modern and well-preserved ones, traditional document scanning systems are suitable for their correct digitization, and, consequently, for their preservation; however, the digitization of ancient, fragile and damaged manuscripts is still a formidable challenge for conservators. The X-ray tomographic approach has already proven its effectiveness in data acquisition, but the algorithmic steps from tomographic images to real page-by-page extraction and reading are still a difficult undertaking. In this work, we propose a new procedure for the segmentation of single pages from the 3D tomographic data of closed historical manuscripts, based on geometric features and flood fill methods. The achieved results prove the capability of the methodology in segmenting the different pages recorded starting from the whole CT acquired volume.

- Abstract
Objectives: During the middle-to-upper Paleolithic transition (50,000 and 40,000 years ago), interaction between Neanderthals and Homo sapiens varied across Europe. In southern Italy, the association between Homo sapiens fossils and non-Mousterian material culture, as well as the mode and tempo of Neanderthal demise, are still vividly debated. In this research, we focus on the study of two human teeth by using 3D geometric morphometric approaches for a reliable taxonomical attribution as well as obtaining new radiometric dates on the archeological sequence., Material and Methods: This work presents two lower deciduous molars uncovered at Roccia San Sebastiano (Mondragone-Caserta, Italy), stratigraphically associated with Mousterian (RSS1) and Uluzzian (RSS2) artifacts. To obtain a probabilistic attribution of the two RSS teeth to each reference taxa group composed of Neanderthals and Homo sapiens, we performed and compared the performance of three supervised learning algorithms (flexible discriminant analysis, multiadaptive regression splines, and random forest) on both crown and cervical outlines obtained by virtual morphometric methods., Results: We show that RSS1, whose Mousterian context appears more recent than 44,800-44,230 cal BP, can be attributed to a Neanderthal, while RSS2, found in an Uluzzian context that we dated to 42,640-42,380 cal BP, is attributed to Homo sapiens., Discussion: This site yields the most recent direct evidence for a Neanderthal presence in southern Italy and confirms a later shift to upper Paleolithic technology in southwestern Italy compared to the earliest Uluzzian evidence at Grotta del Cavallo (Puglia, Italy)., (© 2022 The Authors.

- Abstract
The Bologna Archaeological Museum, in cooperation with prestigious Italian universities, institutions, and independent scholars, recently began a vast investigation programme on a group of Egyptian coffins of Theban provenance dating to the first millennium BC, primarily the 25th-26th Dynasty ( c. 746-525 BC). Herein, we present the results of the multidisciplinary investigation carried out on one of these coffins before its restoration intervention: the anthropoid wooden coffin of Un-Montu (Inv. MCABo EG1960). The integration of radiocarbon dating, wood species identification, and CT imaging enabled a deep understanding of the coffin's wooden structure. In particular, we discuss the results of the tomographic investigation performed in situ. The use of a transportable X-ray facility largely reduced the risks associated with the transfer of the large object (1.80 cm tall) out of the museum without compromising image quality. Thanks to the 3D tomographic imaging, the coffin revealed the secrets of its construction technique, from the rational use of wood to the employment of canvas ( incamottatura ), from the use of dowels to the assembly procedure.

- Abstract
Neanderthal foot bone proportions and morphology are mostly indistinguishable from those of Homo sapiens, with the exception of several distinct Neanderthal features in the talus. The biomechanical implications of these distinct talar features remain contentious, fueling debate around the adaptive meaning of this distinctiveness. With the aim of clarifying this controversy, we test phylogenetic and behavioral factors as possible contributors, comparing tali of 10 Neanderthals and 81 H. sapiens (Upper Paleolithic and Holocene hunter-gatherers, agriculturalists, and postindustrial group) along with the Clark Howell talus (Omo, Ethiopia). Variation in external talar structures was assessed through geometric morphometric methods, while bone volume fraction and degree of anisotropy were quantified in a subsample (n = 45). Finally, covariation between point clouds of site-specific trabecular variables and surface landmark coordinates was assessed. Our results show that although Neanderthal talar external and internal morphologies were distinct from those of H. sapiens groups, shape did not significantly covary with either bone volume fraction or degree of anisotropy, suggesting limited covariation between external and internal talar structures. Neanderthal external talar morphology reflects ancestral retentions, along with various adaptations to high levels of mobility correlated to their presumably unshod hunter-gatherer lifestyle. This pairs with their high site-specific trabecular bone volume fraction and anisotropy, suggesting intense and consistently oriented locomotor loading, respectively. Relative to H.sapiens, Neanderthals exhibit differences in the talocrural joint that are potentially attributable to cultural and locomotor behavior dissimilarity, a talonavicular joint that mixes ancestral and functional traits, and a derived subtalar joint that suggests a predisposition for a pronated foot during stance phase. Overall, Neanderthal talar variation is attributable to mobility strategy and phylogenesis, while H. sapiens talar variation results from the same factors plus footwear. Our results suggest that greater Neanderthal body mass and/or higher mechanical stress uniquely led to their habitually pronated foot posture., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

- Abstract
Scientific investigations of artworks are crucial in terms of preservation since they provide a measurable evaluation of the materials and the state of conservation. This is the case of Antonello da Messina's painting "Ecce Homo": its delicate state of conservation, with the need for constant monitoring, required a broad and in-depth diagnostic campaign to support the restorers. The project was carried out entirely in situ using non-invasive cutting-edge techniques and proposes a multimodal and data-centric approach, integrating 3D and 2D methodologies. The surface irregularities and the support were analysed with a structured-light 3D scanner and X-ray tomography. The painting materials were investigated with X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI). Primarily, the data were jointly used for a scientific scope and provided new knowledge of the painting in terms of materials and painting techniques. In addition, two web-based interactive platforms were developed: one to provide restorers and experts with a new perspective of the hidden geometries of the painting, and the other targeted at the general public for dissemination purposes. The results of the Ecce Homo scientific analysis were exhibited, using a touch-screen interface, and developed for different user levels, from adults to kids., (© 2021. The Author(s).)

27. Chemical analysis and computed tomography of metallic inclusions in Roman glass to unveil ancient coloring methods.

- Abstract
This paper describes the analysis of two near-spherical metallic inclusions partially incorporated within two Roman raw glass slags in order to elucidate the process that induced their formation and to determine whether their presence was related to ancient glass colouring processes. The theory of metallic scraps or powder being used in Roman times for glass-making and colouring purposes is widely accepted by the archaeological scientific community, although the assumption has been mainly based on oral traditions and documented medieval practices of glass processing. The analysis of the two inclusions, carried out by X-ray computed tomography, electrochemical analyses, and scanning electron microscopy, revealed their material composition, corrosion and internal structure. Results indicate that the two metallic bodies originated when, during the melting phase of glass, metal scraps were added to colour the material: the colloidal metal-glass system reached then a supersaturation condition and the latter ultimately induced metal expulsion and agglomeration. According to the authors' knowledge, these two inclusions represent the first documented and studied finds directly associated with the ancient practise of adding metallic agents to colour glass, and their analysis provides clear insights into the use of metallic waste in the glass colouring process.

- Abstract
Scientific literature concerning genital bones in primates consists of both ancient works (dating back to the nineteenth century) and more recent revisions/meta-analyses, which, however, are not always so detailed or exhaustive. Based on a thorough analysis, several conflicting data, inaccurate references, and questionable claims have emerged. We generated a binary matrix of genital bone occurrence data, considering only data at the species level, based on (1) a rigorous literature search protocol, (2) raw data (collected exclusively from primary literature), (3) an updated taxonomy (often tracing back to the species taxonomic history) and (4) new occurrence data from scanned genitals of fresh and museum specimens (using micro-computed tomography-micro-CT). Thanks to this methodological approach, we almost doubled available occurrence data so far, avoiding any arbitrary extension of generic data to conspecific species. This practice, in fact, has been recently responsible for an overestimation of the occurrence data, definitively flattening the interspecific variability. We performed the ancestral state reconstruction analysis of genital bone occurrence and results were mapped onto the most updated phylogeny of primates. As for baculum, we definitively demonstrated its simplesiomorphy for the entire order. As for baubellum, we interpreted all scattered absences as losses, actually proposing (for the first time) a simplesiomorphic state for the clitoral bone as well. The occurrence data obtained, while indirectly confirming the baculum/baubellum homology (i.e., for each baubellum a baculum was invariably present), could also directly demonstrate an intra-specific variability affecting ossa genitalia occurrence. With our results, we established a radically improved and updated database about the occurrence of genital bones in primates, available for further comparative analyses.

- Abstract
An isolated human cranium, dated to the early Eneolithic period, was discovered in 2015 at the top of a vertical shaft in the natural Marcel Loubens gypsum Cave (Bologna area, northern Italy). No other anthropological or archaeological remains were found inside the cave. In other caves of the same area anthropic and funerary use are attested from prehistory to more recent periods. We focused on investigating the circumstances surrounding the death of this individual, since the cranium shows signs of some lesions that appear to be the results of a perimortem manipulation probably carried out to remove soft tissues. Anthropological analyses revealed that the cranium belonged to a young woman. We analysed the taphonomic features and geological context to understand how and why the cranium ended up (accidentally or intentionally) in the cave. The analyses of both the sediments accumulated inside the cranium and the incrustations and pigmentation covering its outer surface suggested that it fell into the cave, drawn by a flow of water and mud, likely from the edges of a doline. The accidental nature of the event is also seemingly confirmed by some post-mortem lesions on the cranium. The comparison with other Eneolithic archaeological sites in northern Italy made it possible to interpret the find as likely being from a funerary or ritual context, in which corpse dismemberment (in particular the displacement of crania) was practiced., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Objectives: We aim to discuss the presence of treponemal infections in three individuals belonging to a large (∼400 individuals) Late Medieval cemetery (14th -16th century) that archaeological and documentary sources place within a Jewish context, and to discuss the role of these diseases in a biocultural perspective., Materials and Methods: An anthropological and paleopathological study was conducted on skeletal remains of three individuals, though macroscopic and tomographic examination., Results: Cranial lesions in which simultaneous destructive and proliferative processes (caries sicca) are noted. Long bones also present osseous alterations with increased bone density and non-uniform thickening., Conclusions: Skeletal lesions are consistent with treponemal infections (possibly either endemic or acquired syphilis). Historical documentation could help the interpretation of our cases, recording a syphilis outbreak in Bologna in 1496, possibly coeval to the Late Medieval Jewish cemetery., Significance: These cases of treponematosis are unique, documenting the presence of the disease within the Jewish Medieval community in Italy, as they frame the effects and consequence of the infection in shaping social and cultural contexts of the medieval Italian and European communities. They offer material evidence to elaborate on the historical documents on the hostility Jewish community suffered., Limitations: Radiocarbon dating have not been performed directly on skeletal remains of the three pathological individuals. δ
13 C and δ15 N isotope ratios should also be acquired to estimate the marine diet component, to account for possible marine reservoir effect on radiocarbon age calibration., (Copyright © 2020 Elsevier Inc. All rights reserved.)- Published

- Abstract
Novel bio-imaging techniques such as micro-Computed Tomography provide an opportunity to investigate animal anatomy and morphology by overcoming limitations imposed by traditional anatomical drawings. The primate genital bones are complex anatomical structures whose occurrence in both male penis (baculum) and female clitoris (baubellum) may be difficult to assess in individual cadavers. We tested a 3-step methodological protocol, including different techniques ranging from inexpensive/simple to more expensive/sophisticated ones, by applying it to a sample of primate species, and resulting in different levels of data complexity: (1) presence/absence manual palpation method; (2) 2D X-ray plates; 3) 3D micro-CT scans. Manual palpation failed on 2 out of 23 specimens by detecting 1 false negative and 1 false positive; radiography failed once confirming the false positive, however firmly disproved by micro-CT; micro-CT analysis reported the presence of 9 bacula out of 11 male specimens and 1 baubellum out of 12 female specimens. A different baculum position was identified between strepsirrhine and haplorrhine species. We also aim to assess micro-CT as a non-invasive technique providing updated anatomical descriptions of primate ossa genitalia. Micro-CT 3D volumes showed the surface of some bones as rough, with a jagged appearance, whereas in others the surface appeared very smooth and coherent. In addition, four main types of bone internal structure were identified: 1) totally hollow; 2) hollow epiphyses and solid diaphysis with few or several channels inside; 3) totally solid with intricate Haversian channels; 4) totally solid with some channels (structure of single baubellum scanned). Ossa genitalia appeared as a living tissue having its own Haversian-like channels. The high resolution of micro-CT 3D-images of primate genital bones disclosed additional form variability to that available from genital bone 2D images of previous studies, and showed for the first time new internal and external morphological characters. Moreover, micro-CT non-invasive approach proved appropriate to recover much of scientific knowledge still hidden and often neglected in both museum specimens and primate cadavers only destined to necropsy., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background and Aims: The Case/Care Manager (CCM) is a new position for in the Italian National Health Service scenario. Job satisfaction plays a key role for the CCM to engage in his work, accomplishing it in a complete. Nurses' job satisfaction is a complex construct and many different variables can influence it: personal characteristics, cultural characteristic, social characteristic, organizational characteristic, and environmental characteristic. The main aim of this study is to assess the job satisfaction in a sample of CCM and to assess if and how Social Variables (organizational climate and health) and Individual (socio-demographic variables, coping strategies, emotion regulation) relate to the CCM job satisfaction., Methods: This study has a quantitative exploratory cross-sectional design. Participants were Nurse CCM with or without specific training who filled a battery of questionnaires : Job Satisfaction Survey (JSS) , section three of ICONAS questionnaire, section five of the Multidimensional Organizational Health Questionnaire (MOHQ), anamnestic sheet, Coping Orientation to the Problems Experienced (COPE-NVI-25), and Emotion Regulation Questionnaire (ERQ). The battery was administered online on the website of Italian Case Manager, Italian Association of Care Manager, and IPASVI Colleges. It was also distributed during the National Congress for Case Manager in Padua., Results: 103 participants took part in the study. The total mean score of JSS was 117,28 (S.D.=21,12). The emotional regulation strategy most used was the "Cognitive Response", and the most used Coping strategy was "Problem Oriented". There were significant correlations between JSS and Social variables in the total score (ICONAS r=.574 p<0.01; MOHQ (positive indicators) r=.608 p<0.01; MOHQ (negative indicators) r=-.634 p <0.01) and in its subscales. There were also significant correlations between JSS subscales and Individual variables (COPE and ERQ). Participants with a specific training tend to use the emotion regulation strategy "Negative interpretation self-oriented" (U 910.500 p<0.005) and "Distraction" (U 885.000 p<0.005) more than those without specific training. The same significant difference was found in JSS pay (t=-2,48 per p<0.05) and JSS Fringe Benefits (t=-2,07 per p<0.05)., Discussion: The CCM job satisfaction seems to be ambivalent. It seems to be not entirely polarized on presence/absence, but rather still in a gray area. organizational climate and health influence significantly the overall perception of job satisfaction and its different areas. The most "avoiding" emotional regulation strategies, seem to negatively affect the perception of satisfaction. Emotional regulation and coping strategies related to challenges focusing and management, along with the individual perception of collaboration, positively influence satisfaction. Participants who underwent a specific CCM training, committing themselves financially and personally, perceive less job satisfaction when their role is not recognized in terms of pay. This study showed that that the main strategies used to regulate emotions are the Cognitive Response and the Social Contact. We suggest that further studies could be made to define the links between individual strategies and the presence of chronic distress and we suggest that a specific training on coping and emotion regulation may be implemented in graduation and post-graduation courses.

- Abstract
The diagnosis of tuberculosis (TB) in osteoarcheological series relies on the identification of osseous lesions caused by the disease. The study of identified skeletal collections provides the opportunity to investigate the distribution of skeletal lesions in relation to this disease. The aim of this study was to examine the skeletal evidence for TB in late adolescent and adult individuals from the identified human collection of the Certosa cemetery of Bologna (Italy, 19th-20th c.). The sample group consists of 244 individuals (138 males, 106 females) ranging from 17 to 88 years of age. The sample was divided into three groups on the basis of the recorded cause of death: TB (N = 64), pulmonary non-TB (N = 29), and other diseases (N = 151). Skeletal lesions reported to be related to TB were analyzed. The vertebral lesions were classified into three types: enlarged foramina (EnF, vascular foramina with diameter of 3-5 mm), erosions (ER), and other foramina (OtF, cavities of various shapes > 3 mm). A CT scan analysis was also performed on vertebral bodies. Some lesions were seldom present in our sample (e.g., tuberculous arthritis). OtF (23.7%) and subperiosteal new bone formation on ribs (54.2%) are significantly more frequent in the TB group with respect to the other groups. The CT scan analysis showed that the vertebrae of individuals who have died of TB may have internal cavities in the absence of external lesions. These traits represent useful elements in the paleopathological diagnosis of TB., (© 2015 Wiley Periodicals, Inc.)

- Abstract
Purpose: The temporal bone includes several important structures of the human body, some of which are smaller than 1 mm. The aim of this study is to demonstrate the feasibility of a computed tomography system capable of providing 3-dimensional images of the inner ear with low doses and a spatial resolution adequate for providing the surgeon with good guidance., Methods: A laboratory prototype, based on a CMOS Hamamatsu model C10900D detector, was set up, and several tomographic tests were carried out on 2 dedicated phantoms., Results: The proposed system is able to achieve a 150-μm spatial resolution (5% of modulation transfer function) with a voxel size of 88 μm, with an acceptable contrast and an estimated effective dose ranging from 1/20 up to 1/100 of the mean effective dose reported in literature for head computed tomography., Conclusion: The new tomographic system has shown excellent characteristics and proves suitable for the imaging of the inner ear. In particular, this prototype requires very low radiation doses.

- Abstract
Purpose: The Monte Carlo (MC) simulation is widely used to design and test complex physical phenomena. This paper presents a simulator of x-ray detector for imaging applications by providing a simple component that can be embedded into a MC code and allowing developers to focus their attention on the primary goals without hanging in the quality of the final output image., Methods: A simplified semiempirical model of x-ray detector was developed and implemented starting from the definition of absorber material and developing scintillator and photoconductor screens and detectors. The validation was done by comparing a Hamamatsu C10900D digital flat panel with a simulation of the same detector using the presented model: MTF, nNPS, and NEQ., Results: The results of validation tests shown excellent agreement of the simulation with respect to the experimental data. The simulation was fast and efficient even in older computers (2004) and it was excellent in newer multicore computers (2010)., Conclusions: Comparisons between experimental data and simulations shown that the simulator is able to mimic the output of a real imaging system, and it can have many applications in fields such as industry, medical physics, and teaching.

- Abstract
Background: Persistent pulmonary hypertension of the newborn (PPHN) is a rare syndrome with a severe prognosis, in which a prompt diagnosis can be life-saving. The aim of our study was to verify its prevalence in a neonatal population, define clinical and echocardiographic criteria for the diagnosis of PPHN and discuss therapeutic choices., Methods: The following clinical and echocardiographic criteria for the diagnosis of PPHN were defined: 1. cyanosis and hypoxemia non-responsive to O2 therapy; 2. right to left shunt at an atrial or ductal level. All neonates fulfilling these criteria referred to the neonatal units of seven pediatric or general hospitals over a two-year period were enrolled., Results: From January 1995 to December 1996, thirty neonates with PPHN (8%) were observed. Birth was pre-term in 5 out of 30. Ten (33%) had experienced chronic and/or fetal asphyxia (FA). Death occurred in 7 (22%), four of whom with FA. Echocardiography showed tricuspid insufficiency in 18 (60%); mean pulmonary systolic pressure was 67 +/- 16 mmHg (range 41-95). In 23 surviving neonates, normalization of clinical and echocardiographic parameters occurred in 8 +/- 5 days., Therapy: In most neonates, vasodilators (tolazoline, prostacyclin) and/or nitric oxide were employed., Conclusions: PPHN is confirmed to be a rare pathological condition; prognosis is severe, particularly in neonates with FA. Echocardiography is a reliable non-invasive method for a prompt diagnosis and follow-up. Subsequent studies are needed to assess therapeutic choices.

- Abstract
Background: The management of patients with isolated congenital complete heart block is controversial, and indications for cardiac pacing are not clearly defined. In the present study we report our long-term experience in the management of patients with this disease., Methods: Thirty-eight consecutive patients aged 2 days to 28 years (mean age 10 years) were studied and followed up for 130 +/- 57 months (range 18 to 274). They underwent an extensive evaluation including history, physical examination, electrocardiography and echocardiography; thirty-seven patients had Holter monitoring and exercise test. Electrophysiologic study was performed in 24 patients., Results: Twenty-two patients were asymptomatic, sixteen had symptoms as syncope or presyncope (7 patients), marked exercise intolerance (1 patient), presyncope and marked exercise intolerance (1 patient), heart failure (1 patient), mild dyspnea on exertion (6 patients). Electrocardiograms showed a narrow QRS in all patients. Holter monitoring showed a marked bradycardia (awake heart rate < or = 55 beats/min in infants, < or = 40 beats/min in children and adults) in 15 patients and junctional pauses of > 3 seconds in 9 of them. The exercise test showed a markedly reduced exercise tolerance in 2 patients and exercise-induced complex ventricular arrhythmias in 3 patients. Echocardiography showed a structurally normal heart and a normal left ventricular function in all patients. The electrophysiologic study always showed a suprahisian site of block. Twenty patients (53%) underwent cardiac pacing at a median age of 14 +/- 10 years and were followed up for 110 +/- 59 months (range 18 to 253) after pacing; prophylactic pacing was performed in 10 patients. Indications for cardiac pacing were: syncope or presyncope (7 patients), presyncope and marked exercise intolerance (1 patient), neonatal heart failure (1 patient), marked exercise intolerance (1 patient), neonatal marked bradycardia (2 patients), marked bradycardia with junctional pauses of > 3 seconds and/or complex ventricular arrhythmias (7 patients), complex ventricular arrhythmias (1 patient). No death occurred during the follow-up. In 9 of 20 patients who had cardiac pacing, indication for this procedure appeared during the follow-up (development of symptoms, marked bradycardia and/or complex ventricular arrhythmias). Complications of pacing were infrequent (9 complications in 7 patients) and mainly occurred in the first years of our experience. At present 12 patients have an atrioventricular sequential pacing and 8 have a rate-responsive ventricular one. All patients who had pacing showed an improvement of exercise tolerance; 11 of them underwent exercise test after pacing which showed a significant increase in exercise duration (from 11.1 +/- 1.9 to 15.3 +/- 1.1 min, p < 0.01). In the 3 patients with complex ventricular arrhythmias we observed their suppression after atrioventricular sequential pacing. At present 35 patients are asymptomatic and 3 have mild dyspnea on exertion., Conclusions: Our results confirm that patients with isolated congenital complete heart block often have symptoms and/or signs of electric instability without symptoms. Cardiac pacing relieves symptoms and improves working capacity. Although in this study we are not able to draw conclusions on the therapeutic value of prophylactic pacing, our favourable follow-up results suggest that this therapeutic approach may prevent complications.

- Abstract
Patients who have undergone surgical repair of congenital heart diseases are usually not allowed to participate in competitive sports. In the present study we report our long-term experience with 9 male athletes aged 17 to 23 years who participate in competitive sports after undergoing surgical repair of ostium secundum atrial septal defect at a median age of 9 years; six of them play football and three of them volleyball. Competitive sport activities began 1 to 5 years after surgical repair. The mean duration of follow-up is 88 +/- 26 months. Sport fitness was granted on the basis of the following criteria: 1) a normal physical examination; 2) a normal working capacity on exercise test; 3) no arrhythmias on exercise test and Holter monitoring, recorded also during sport activities; 4) a normal M-mode and two-dimensional echocardiography, including the normalization of right ventricular size; the persistence of an abnormal ventricular septal motion did not exclude sport fitness. Recently we also performed Doppler and color Doppler echocardiography and gated equilibrium radionuclide angiography at rest and during exercise. We studied left ventricular diastolic filling through the pulsed wave Doppler evaluation of transmitral flow and measured cardiac output by continuous wave Doppler echocardiography during exercise test in the supine position. We also performed exercise test and M-mode, two-dimensional, Doppler and color Doppler echocardiography in a control group made up of 15 athletes (10 football players and 5 volleyball players). The exercise duration at graded treadmill exercise test (according to the Carù protocol), the maximal heart rate and the maximal systolic blood pressure were, respectively, 12.9 +/- 0.8 min, 192 +/- 10 beats/min and 198 +/- 12 mmHg. Left ventricular end-diastolic dimension, mass and ejection fraction (single-plane area-length method) were 50.3 +/- 2.8 mm, 210 +/- 38 g and 65 +/- 6%. M-mode right ventricular diastolic dimension was 23.4 +/- 1.6 mm; the right ventricular maximal diastolic diameter and area obtained on two-dimensional echocardiography from the apical four chamber view were 44.1 +/- 3.6 mm and 25 +/- 3.8 cm2 respectively. The evaluation of transmitral flow showed the following data: E velocity 77 +/- 12 cm/sec, A velocity 45 +/- 6 cm/sec, E/A ratio 1.7 +/- 0.3, the isovolumic-relaxation period 72 +/- 8 m/sec and the deceleration half-time of the early rapid filling 71 +/- 10 m/sec. A trivial tricuspid regurgitation was detected in 6 subjects; the peak velocity of the regurgitant jet was less than 2.1 m/sec.(ABSTRACT TRUNCATED AT 400 WORDS)

- Abstract
Thirty-six infants under one year of age underwent surgical repair of coarctation of the aorta between 1968 and 1983 in our institution. Coarctation was isolated or associated to a patent ductus arteriosus in sixteen cases, while in twenty it was associated with significant intracardiac disease. Twenty-nine patients were operated on in the first three months of life and in twenty a severe heart failure was present before the operation. Nine patients (25%) died while in the hospital: all of them were less than three months of age and all but one were affected by major intracardiac anomalies and severe heart failure. Surgical repair was by subclavian flap aortoplasty in twenty-nine cases, resection with end-to-end anastomosis in three, patch aortoplasty in three and Blalock-Park anastomosis in one. Operative mortality was unaffected by the surgical technique. The surviving children were followed-up for 30 +/- 7 months; one late death occurred suddenly, two months after the repair of a ventricular septal defect. An arm/leg pressure gradient, indicative of recoarctation, was detected in five cases: only one had been repaired by the subclavian flap technique, while the others were the only survivors of the end-to-end anastomosis and patch aortoplasty group. Subclavian flap aortoplasty is suggested as the operation of choice for coarctation of the aorta in the first year of life.
