Socio-Demographic Vulnerability of Youth
2008
For a kind of inertia effect, the Italian welfare state protects today the old age too intensely while little the new risks associated with other phases of life course. Young Italians seem to suffer the actual changes: “youth remain longer in parental home and postpone the creation of its own independent life to most advanced age”. To understand the vulnerability situation increasingly widespreading among young people, it seems more and more necessary the depth analysis of the reasons and the subjective status of this discomfort that occur through a delay in transition to adulthood. In particular we study the self-perceived vulnerability situation of young Italians in the labor market (both…
Un approccio innovativo per la modellazione degli edifici in muratura intelaiata. Applicazione ad un caso di studio
2013
Le strutture in muratura intelaiata rappresentano una parte rilevante delle strutture esistenti e sono ancora largamente adottate come sistema strutturale per la costruzione di edifici residenziali, soprattutto in aree del mondo a forte sismicità non fortemente industrializzate e nelle quali la muratura rappresenta ancora un materiale tradizionale e a basso costo. In questo lavoro viene presentato un approccio per macro-elementi per la valutazione della risposta sismica di strutture in muratura confinata. La complessa interazione tra il telaio e la muratura è simulata mediante un approccio originale in cui il telaio è modellato con aste a plasticità concentrata mentre il contributo della mu…
Physiological incongruity of the humero-ulnar joint: a functional principle of optimized stress distribution acting upon articulating surfaces?
1993
Investigations into the distribution of subchondral bone density in the human elbow have suggested that the geometry of the trochlear notch deviates from a perfect fit with the trochlea, and that the load is transmitted ventrally and dorsally rather than through the centre of the humero-ulnar joint. We therefore decided to make a quantitative assessment of the degree of incongruity between the two components in 15 human specimens (age distribution 60 to 93 years) with different types of joint surface. Polyether casts of the joint cavity were prepared under loads of 10, 40, 160 and 640 N. The thickness of the casts was then measured at 50 predetermined points, and an area distribution of the…
Physiotherapists’ experiences of direct access for clients with musculoskeletal pain and dysfunction: a qualitative study
2019
Aims: The aim of this study was to qualitatively analyse physiotherapists’ experiences and perspectives for delivering services directly, without prescription or referral, for clients with musculoskeletal pain or dysfunction. Methods: This was a qualitative study where data were collected from questionnaires given to 34 physiotherapists, 18 of them being in direct access for 6 years and 16 for 6 months. There were 15 structured questions and 3 open-ended ones. The answers were analysed with quantitative and qualitative methods. Results: The data analysis of the open-ended questions showed that physiotherapists had positive experiences of direct access. This practice brought meaningfulness, …
The radial artery is larger than the ulnar.
2003
The radial artery is presently widely used as a bypass graft for coronary artery reconstruction. However, the traditional opinion that the ulnar artery is the larger forearm artery has been questioned.The internal diameters of the radial and ulnar arteries were measured at the wrist in postmortem angiograms of 24 cadavers. Differences in mean values of variables between ulnar and radial arteries were analyzed using the Wilcoxon test.The mean diameter of the radial artery was 28% larger than that of the ulnar artery in the right arm (p0.001) and 26% larger in the left arm (p0.001). In the right arm the radial artery was dominant in 20 of 24 cadavers (83%), the ulnar artery in 3 of 24 (13%), …
Kinematics of the ulna during pronation and supination in a cadaver study: implications for elbow arthroplasty
2003
Objective. Aim of this study was to exactly describe and quantify kinematics of the ulna during pro- and supination. Design. Biomechanical study in fresh frozen cadavers. Background. A previous MRI study revealed a varus/valgus motion of the ulna averaging 7.1° during pro-/supination. Axial rotation, however, could not be quantified. Methods. Sixteen arms were examined in a new apparatus that fixed the humerus on a template and allowed forearm rotation. Motion of a Kirschner wire placed in the ulna was recorded in steps of 30° by two perpendicularly arranged charge coupled device cameras during pro- and supination. Results. From supination to pronation the ulna showed a semi-lunar evasive m…
Ultrasound-guided musculoskeletal interventional procedures around the elbow, hand and wrist excluding carpal tunnel procedures.
2021
Ultrasound is a fast, reliable and radiation-free method for the assessment of a wide range of pathological conditions, as well as for the guidance of percutaneous interventional procedures around the elbow, hand and wrist. Intraarticular and periarticular interventional procedures can be easily performed under continuous ultrasound monitoring to ensure correct needle positioning and medication delivery to a specific target. The most common ultrasound-guided procedures performed around the elbow, wrist, and hand are described in this review, excluding carpal tunnel procedures. Specifically, elbow steroid injections are performed in patients with inflammatory disorders, while hyaluronic acid…
Spätsynovektomie des Ellenbogens und Resektion des Radiusköpfchens bei chronischer Polyarthritis
2008
Between 1974 and 1984 16 patients with rheumatoid arthritis, who had elbow synovectomy and excision of the radial head, were revised with an average follow-up of 5 years after operation. Resection of the radial head was performed on 16 elbows, in 3 elbows the ulnar nerve was transposed. The indication for the operation were pain, swelling, warmth and radiological destruction. The parameters used, to assess efficacy of the operation were range of motion, local finding and patient satisfaction. Synovectomy results were good especially in respect of relief of pain and range of motion. The good results justify elbow synovectomy even in the late stages of disease.
Criteri per l’analisi post-danno – Criteria for post-damage analysis.
2010
Gli elementi non-strutturali risultano assai più vulnerabili al sisma delle strutture, così come reso evidente dai terremoti che nell’ultimo decennio hanno colpito il nostro paese. Il danneggiamento di tali elementi, oltre a mettere a serio rischio la sicurezza degli edifici, e dunque l’incolumità, spesso rende diseconomici, disagevoli o addirittura impraticabili gli interventi di riparazione degli edifici. Ciò anche quando questi sono a struttura intelaiata e progettati e realizzati con criteri antisismici e le strutture non hanno subito danni di rilievo. D’altronde il comportamento sismico degli elementi non strutturali è stato lungamente trascurato e dall’analisi dello stato dell’arte in…
