Inhibition of Fenton reaction is a novel mechanism to explain the therapeutic effect of intra-articular injection of PRP in patients with chronic haemophilic synovitis.

Introduction And Aim: Haemarthroses cause major morbidity in haemophilia resulting in chronic haemophilic synovitis (CHS) and arthropathy. Oxidation of haemoglobin-coupled iron released in synovium after haemolysis induces chondrocytes death and cartilage damage, allowing postulate using iron-chelating drugs as potential therapeutic tool for haemophilic joint damage. Considering that albumin, the most abundant plasma protein, is a physiologic iron chelator, we aim to demonstrate that impediment of haemoglobin oxidation is exerted by plasma as a mechanism involved in the therapeutic effect of intra-articular injection of platelet-rich plasma in CHS.

Percutaneous fixation of acetabular fractures.

The objective of surgery for acetabular fractures is to achieve precise reduction to restore joint congruence, fix internal bone fragments, avoid displacement of the fracture and allow rapid rehabilitation.Open reduction and internal fixation is the benchmark method for displaced acetabular fractures, but open reductions can increase morbidity, causing neurovascular injury, blood loss, heterotopic bone formation, infection and poor wound healing.An anatomical reduction with a gap of 2 mm or less is a predictor of good joint function and reduced risk of post-traumatic osteoarthritis.

Platelet Rich Plasma for Chronic Synovitis Treatment in Patients with Haemophilia.

Introduction: Haemophilic synovitis is caused by chronic accumulation of blood in the joint. Conservative treatment is insufficient to solve this pathology. Platelet-rich plasma (PRP) has a high concentration of growth factors (GFs) that play a key role in regulation and stimulation of healing processes.

Epidemiology of fractures in patients with haemophilia.

Introduction: Haemophilia is an X-chromosome linked inherited bleeding disorder characterised by an anomaly synthesis of coagulation factor VIII (Haemophilia A) or factor IX (Haemophilia B). There is very little information on the magnitude and management of fractures in PWH in the literature regards the advance on replacement therapy. The purpose of this paper is to present our 28 years experience treating PWH who suffered fractures and evaluate the impact of access to treatment.

Haemophilia pseudotumours in patients with inhibitors.

Development of inhibitors against factor VIII (FVIII) or FIX is the most serious complication of replacement therapy in patients with haemophilia. Haemophilic pseudotumours in a patient with inhibitors can lead to devastating consequences. The aim of this study is to show our experience in the treatment of 10 pseudotumours in 7 patients with inhibitors who were treated by the same multidisciplinary team in the period between January 2000 and March 2013.

Cavernous sinus tuberculoma mimicking a neoplasm: Case report, literature review, and diagnostic and treatment suggestions for tuberculomas in rare locations.

Background: Cavernous sinus tuberculomas are extremely rare, but the increasing incidence worldwide of central nervous system (CNS) tuberculosis, mostly due to human immunodeficiency virus and poor sanitary conditions, and the ability of tuberculomas to mimic a brain neoplasm makes cavernous sinus tuberculomas a suspicious pathologic finding in the differential diagnosis of a brain space-occupying lesion.

Case Description: We present an immunocompetent patient with no signs of systemic tuberculosis and an isolated right cavernous sinus space-occupying lesion. A skull base approach was performed and tumor resection achieved.
