Alterations in vitamin D homeostasis, mainly involving its nuclear receptor (VDR), could have a role in the pathophysiology of the spine. The association between VDR polymorphisms and spine disorders has been analyzed in different ethnic groups, focusing on the functional FokI polymorphism. However, so far, inconsistent findings were reported. The aims of(More)
Loss of articular cartilage through injury or disease presents major clinical challenges also because cartilage has very poor regenerative capacity, giving rise to the development of biological approaches. As autologous blood product, platelet-rich plasma (PRP) provides a promising alternative to surgery by promoting safe and natural healing. Here we tested(More)
A large body of evidence attests that quality programs developed around the analytical phase of the total testing process would only produce limited improvements, since the large majority of errors encountered in clinical laboratories still prevails within extra-analytical areas of testing, especially in manually intensive preanalytical processes. Most(More)
Biochemistry and haematology are more and more important and sometimes crucial in sport medicine for diagnosing, controlling and preventing purposes. The analytical process and the global laboratory quality are heavily influenced by the preanalytical phase, including biological material collection, identification, storage and transport of the specimen,(More)
OBJECTIVES We performed a systematic review of current evidence regarding ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) in the shoulder aimed to: assess different published techniques; evaluate clinical outcome in a large combined cohort; and propose suggestions for homogeneous future reporting. METHODS Cochrane(More)
Anticoagulants are used to prevent clot formation both in vitro and in vivo. In the specific field of in vitro diagnostics, anticoagulants are commonly added to collection tubes either to maintain blood in the fluid state for hematological testing or to obtain suitable plasma for coagulation and clinical chemistry analyses. Unfortunately, no universal(More)
BACKGROUND After the introduction of microsurgical principles in endodontics involving new techniques for root canal treatment, there has been a drive to enhance the visualisation of the surgical field. It is important to know if the technical advantages for the operator brought in by magnification devices such as surgical microscopes, endoscopes and(More)
Human growth hormone (hGH) characteristically increases during physical exercise. In sports medicine, hGH changes have mostly been described in short-term performances under standardized laboratory procedures. We studied hGH and insulin-like growth factor I (IGF-I) under field conditions in 7 runners performing a marathon at 4000 m of altitude, to study the(More)
T he use of platelet rich plasma (PRP) has been proposed for tendon and ligament healing. The rationale is the release of large amounts of growth factors and cytokines with regenerative, anabolic, and anti-inflammatory effects on damaged tissues. We applied PRP in tendinopathies of professional athletes. PRP was obtained using the gravitational platelet(More)
AIM The efficacy of PRP in the treatment of tendinopathies has been already studied both in in vitro and in clinical studies. This paper describes the local and the systemic effects of US-guided autologous PRP (Platelet Rich Plasma) injections in chronic tendinopathies in sportspersons. METHODS Fifteen patients (13 male, 2 female) between 17 and 68 years(More)
