Health-Related Field-Based Fitness Tests: Normative Values for Italian Primary School Children.

conducting fitness tests in educational settings can lead to advantages for both individuals and groups, beyond just enhancing fitness. With the aim of appropriately interpreting performance, this study was conducted to establish sex- and age-specific percentile normative data for a physical fitness (PF) protocol and to define a compound measure of physical performance. In this cross-sectional study, a short, feasible, and easy-to-administer test battery was performed for 5106 school children, aged 6-10 years.

School self-efficacy is affected by gender and motor skills: findings from an Italian study.

Background: Perceived school self-efficacy (SE) is an important variable in students' activities as it affects their motivation and learning. Further, self-efficacy might represent a good predictor of performance, persistence and perseverance. Motor skills and other physical health determinants are extensively debated and linked to cognitive function in children of developmental age.

Six minute walk distance and reference values in healthy Italian children: A cross-sectional study.

The 6-minute walking test (6MWT) is a simple assessment tool to evaluate exercise capacity. The result of the test is the distance that a subject can walk at a constant and normal pace within 6 minutes (6MWD) and reflects the aerobic/fitness performance related to walking function. Use of 6MWT has been relevant to assess exercise tolerance either in healthy children or in patients with, heart, lung and metabolic diseases.

Urban and rural fitness level: comparison between Italian and Croatian students.

The goal of this study was to investigate the differences in physical fitness in relation to urban or rural living environment and between two countries: Italy and Croatia. Over 14,000 students were tested during physical education (PE) lessons. Croatian students were taller and heavier than Italian students, with women achieving better results in flexibility.

Medical robotics.

Information and communication technology (ICT) and mechatronics play a basic role in medical robotics and computer-aided therapy. In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery.

In vivo assessment of coronary stents with 64-row multidetector computed tomography: analysis of metal artifacts.

Objective: To evaluate stent-induced artifacts by 64-row multidetector computed tomography (MDCT).

Methods: We studied 26 stented patients with MDCT before conventional coronary angiography (CCA). The CT values were measured.

A new device to seal large coronary aneurysms: a case report.

Introduction: Coronary artery aneurysm is an uncommon disease. It is defined as a coronary artery dilatation, exceeding the diameter of the normal adjacent segment or the diameter of the patient's largest coronary vessel by 1.5 to 2 times.

Diagnostic work up of arrhythmogenic right ventricular cardiomyopathy by cardiovascular magnetic resonance (CMR). Consensus statement.

Cardiovascular Magnetic Resonance (CMR) has become a widespread diagnostic tool. Since its introduction CMR has been used to image patients with known or suspected arrhythmogenic right ventricular cardiomyopathy (ARVC). Several abnormalities have been found and described by CMR and at present this diagnostic tool is considered very important for the diagnosis.

Acute spontaneous aortic pathologies associated with intramural hematoma: can a differential diagnosis be made by imaging techniques?

Acute intramural aortic hematoma may result from ruptured vasa vasorum without intimal disruption (IMH hereafter) but can also be found in association with processes in which an intimal lesion is present, such as aortic dissections (AD), where the hematoma represents the acute thrombosis of the false lumen, or in penetrating atherosclerotic ulcers (PAU), where blood collects beyond the disrupted internal elastic lamina. As the clinical presentation of these conditions is very similar, imaging techniques should aim both to diagnose the hematoma and to characterize the underlying pathology. This review critically analyzes the diagnostic potential of several imaging methods based on personal experience and literature reports.

A model of an electro-goniometer and its calibration for biomechanical applications.

The paper describes a detailed model of an electro-goniometer based on a elastic beam connecting two 'bases' whose relative orientation should be measured. This kind of device, which has been developed for the analysis of human motion, is also suitable for different applications even when one or more rotations around moving axes occur. After a theoretical analysis of the device working principles, experimental verifications of the model are presented.

TAT, F1 + 2, and D-dimer levels in patients after coronary angiography with nonionic or ionic contrast media or after cardiac catheterization.

The prothrombotic effects of nonionic contrast media (NICM) have been evaluated in both biological and clinical studies. The question of whether there is a higher risk of thromboembolism during angiography with NICM than with ionic contrast media (ICM) has not yet been answered, nor has the precise role of the angiographic procedure per se in such complications been determined. The present study was performed to compare in vivo the potential prothrombotic effects during cardiac angiography of an NICM with those of an ICM, to estimate the effects of the procedure per se, and to assess how long these effects might be maintained.

CT demonstration of liquid intratumoral fat layering in a necrotic renal cell carcinoma.

We describe a case of clear-cell adenocarcinoma of the kidney with CT evidence of fat that contradicts the rule that radiologically demonstrable fat is absent in renal carcinoma. The cyst-like appearance, egg-shell parietal calcifications, and extrarenal development of the mass suggested a preoperatively incorrect diagnosis of teratoma.

Sonography after renal biopsy: assessment of its role in 230 consecutive cases.

Among 230 patients undergoing ultrasound (US) guided renal biopsy, 218 had postbiopsy sonography. Clinical records were reviewed to correlate symptoms to US findings. In each case of large hematoma (thickness above 1 cm), all postbiopsy sonographic studies were analyzed to look for findings indicative of unfavorable outcome.

[Surgical revascularization of the myocardium for atresia of the left main coronary artery and atherosclerotic coronary disease].

The authors report a rare case of atresia of the left main coronary artery in an adult patient, symptomatic for effort angina. At coronarography, the left main coronary artery was not found; instead, the arteries of the left coronary tree were filled via a single collateral vessel arising from the ostium of the right coronary artery and ending in the trunk of the left anterior descending artery. All left arteries had very narrow calibres, almost hypoplastic, while the right coronary artery had a normal calibre.

Preliminary study of a new fixation device for intertrochanteric femoral fractures.

The authors present a preliminary study on the treatment of intertrochanteric fractures with a reinforced 95 degrees blade-plate, devised and used at the II Orthopedic Dept. of the University of Milan, in cooperation with the Milan Polytechnic. They discuss the indications and clinical-radiographic findings of the first 14 cases operated on, with a mean follow up of two years.

[Echocardiographic evaluation of mitral valve calcification].

Preoperative assessment of calcifications is important in order to choose the correct surgical approach for mitral valve disease. To test the accuracy of echocardiography (ECHO) in the semiquantitative analysis of mitral valve (MV) calcifications we preoperatively echo-studied 66 patients, who were to undergo MV replacement of rheumatic disease. Echocardiograms were performed using a standardized method, recorded on videotape and analyzed by two independent observers.

[Proposal of a standardized graphic system for collecting coronary angiographic data. Processing with a personal computer].

A standardized method for the representation and filing of coronary angiographies is proposed. Semi-automatic reference is guided by a computer algorithm. The final report displays a diagram which shows all the information in graphic and alpha-numeric form.

MRI as an adjunct to echocardiography for the diagnostic imaging of cardiac masses.

Nine patients underwent magnetic resonance imaging (MRI) as part of the diagnostic evaluation for cardiac masses; eight of them had been preliminarily studied by 2D-echocardiography (US). MRI did not add to the US diagnostic information in patients affected by intracavitary masses. It represented the definitive diagnostic modality in two patients with intramural pathology: one with ventricular rhabdomyoma, the second with an echinococcyal cyst located within the left atrial wall.

[Intracavitary and parietal cardiac measurement with nuclear magnetic resonance: comparison with echocardiography in healthy volunteers].

For quantitative evaluation of cardiac dimensions by Nuclear Magnetic Resonance (NMR), we compared the values obtained by ECG gated NMR with those obtained by two-dimensional echocardiography (2D-echo) in 18 adult healthy volunteers aged 20-40 years (mean 31.6 +/- 5.8).
