Le Fratture di Rotula
2015
Patellar fractures are relatively uncommon, accounting for approximately 1% of all fractures. Non-operative treatment represents the best choice for undisplaced patellar fractures. However, surgery becomes necessary when fractures are displaced by more than 2 mm, and may include open reduction and internal fixation. Accurate reduction and rigid fixation are required in order to allow early knee mobilization and to obtain a better clinical outcome. Several techniques have been described for patellar fracture fixation, such as tension band wiring, interfragmentary screw fixation, and the combination of screw fixation and cerclage. In this article up-to-date diagnosis, classification and treat…
A Locked Intraosseous Nail for Transverse Patellar Fractures: A Biomechanical Comparison with Tension Band Wiring Through Cannulated Screws.
2018
Background Displaced transverse patellar fractures require open reduction and internal fixation. State-of-the-art stabilization techniques are tension band wiring (TBW) using Kirschner wires or cannulated screws. These techniques are associated with high rates of secondary fracture displacement, implant migration, implant prominence, wound-healing disturbances, and the need for implant removal. Recently, a locked intraosseous patellar nail prototype was developed. The aim of the present study was to investigate the biomechanical performance of this nail compared with TBW using cannulated screws. Methods Seven paired fresh-frozen human cadaveric knees were stripped of all soft tissues except…
(i) Comminuted patellar fractures
2006
Summary Purpose of review This article reviews current best practice for the diagnosis and treatment of comminuted patellar fractures. Recent findings Patellar fractures make up about 1% of all fractures. As a rule, fractures of the patella are caused by direct trauma to the knee. A transverse fracture is the most common fracture type. Open reduction and internal fixation is the treatment of choice for the majority of displaced patellar fractures. Treatment must achieve anatomic reduction of the articular surface and reestablish the continuity of the extensor mechanism. Tension-band wiring, interfragmentary screw fixation and a combination of cerclage wiring and screw fixation are the most …
The revised ghent nosology; reclassifying isolated ectopia lentis
2014
Inherited ectopia lentis (EL) is most commonly caused by Marfan syndrome (MFS), a multisystemic disorder caused by mutations in FBN1. Historically the diagnosis for patients with EL who have no systemic features of MFS is isolated EL (IEL). However, the Ghent nosology for MFS was updated in 2010 and made some important alterations. In particular, patients with EL and a FBN1 mutation are now categorically diagnosed with MFS, if their mutation has previously been described with aortic dilation/dissection. This carries significant systemic implications, as many patients previously diagnosed with IEL are now reclassified. We provide a review of all published cases of IEL caused by FBN1 mutation…
"Okei, kokeillaan! N-Y-T nyt!" : lasten musiikillinen ryhmäluovuus iPadeilla ja koulusoittimilla
2016
Luovuuden ja musiikillisen improvisaation sekä musiikkiteknologian käytön osuus uudessa musiikin Perusopetuksen opetussuunnitelmassa (2014) lisääntyy ja omaa musiikillista keksintää tulisi olla kaikilla luokka-asteilla. Siksi onkin tärkeää tarkastella, onko tietoteknisten laitteiden käytöllä improvisaation ja musiikillisen luovuuden opetuksessa joitain erityisiä etuja verrattuna tavallisilla soittimilla musisoimiseen. Tässä maisteritutkielmassa vertailtiin luovaa musiikillista keksintää ryhmämusisointitilanteissa iPadeilla ja koulusoittimilla musisoitaessa. Tavoitteena oli tutkia, miten oppilaat kokivat luovan musiikillisen keksinnän koulusoittimilla ja iPadeilla GarageBand-musiikkiohjelmal…

Muutokset naissalibandypelaajien voima- ja nopeusominaisuuksissa kilpailukauden aikana
2016
Salibandya on tutkittu kohtalaisen vähän huolimatta sen suosion suuresta kasvusta viime vuosina. Varsinkaan naispelaajien suorituskyvystä ei ole tutkimustietoa. Tämän tutkimuksen tarkoituksena oli selvittää kilpailukauden aikaisia muutoksia naispelaajien voima- ja nopeusominaisuuksissa. Suorituskyvyn ylläpitäminen ja jopa parantaminen kilpailukauden aikana on tärkeää, sillä kauden tärkeimmät ottelut pelataan kilpailukauden lopussa runkosarjan jälkeen. Tutkimus toteutettiin kaudella 2014–15 ja koehenkilöinä toimi naisten salibandyliigajoukkueen kenttäpelaajia (n = 11–13). Pelaajien suorituskykyä mitattiin ennen runkosarjan alkua (pre), noin runkosarjan puolessa välissä (middle) sekä runkosar…

Aggiornamento sulla nidificazione della Tartaruga marina Caretta caretta (Reptilia Cheloniidae) in Sicilia. Riflessioni sul valore della Citizen Scie…

Updating of egg-laying of Loggerhead sea Turtle Caretta caretta (Reptilia Chelonidae) in Sicily. Remarks on the value of the Citizen Science. The aim of this paper is to put together data on the egg- laying by the Loggerhead sea Turtle Caretta caretta in Sicily, mainly after recordings by amateurs, tourists and occasional observers. 25 nesting events by this turtle are reported in the main island in 2017 and 2018. Comparing these figures with past records, they appear very high; it may be in part due to an awareness campaign carried out in the last years to solicit such reports. This suggests that Sicily may host a much higher nesting population of the Loggerhead sea Turtle than previously …
MAKE LIFE EASIER ON CAMPUS WITH HIGH-SPEED NETWORK
2012
In this paper I have shown that with the evolution of technology, networks and the Internet have become an almost daily necessity, being an essential part of our individual, economic and social life. On their well-functioning depend our governmental, commercial and even personal activities. The modern information society is already a reality, which ignores frontiers which may pass any spatial or temporal limitations due to the communication system. Economy, politics and society today are based ever more on a computerized infrastructure.
