OBJECTIVE IL-4 plus IL-10 prevents blood-induced cartilage damage. The aim of the present study was to evaluate whether cartilage damage can still be averted by addition of IL-4 plus IL-10 when added after the onset of a bleed and whether aspiration of blood prior to addition of IL-4 plus IL-10 is of additive protective value. METHODS Healthy canine hip and human shoulder cartilage was expose...

In a European multicentre study, 39 ankles in 28 haemophilic boys were investigated by magnetic resonance imaging (MRI). A new MRI score was developed in the format A(e:s:h) for evaluating haemophilic arthropathy. This scheme provides high resolution and allows separation of different pathological components. The factor A is calculated as the sum of scores for subchondral cysts (maximum value 6...

Attendances at the Regional Haemophilia Reference Centre in the Edinburgh Royal Infirmary have been analysed over a period of five years from 1969 to 1973. Of 77 patients registered in 1969, 64 had haemophilia A (factor VIII deficiency) and 13 had haemophilia B (factor IX deficiency). In 1973 the numbers were 68 and 14 respectively. An increased attendance at the Centre from 123 in 1969 to 624 ...

Spontaneous haemorrhage in patients with haemophilia is generally considered to occur randomly and without a predictable temporal or seasonal pattern; however, there is a lack of evidence in the literature on the effects of weather, temperature and atmosphere on bleeding episodes. This post hoc analysis of a multicentre, open-label crossover study examined the influence of seasonality on bleedi...

The results of total knee replacement in five patients aged between 22 and 37 with severe haemophilia A or B are described. All patients had been managed conservatively without success. Frequent bleeds, severe pain and limitation of movement were the indications for operation. Despite close haematological surveillance, bleeding problems occurred in three of the patients and large quantities of ...

Arthropathy is a frequent and serious complication of repeated joint bleeding in patients with hemophilia, resulting in pain, deformity, and disability. Although the pathogenesis of hemophilic arthropathy has not been fully elucidated, it appears to have similarities with the degenerative joint damage that occurs in osteoarthritis and the inflammatory processes associated with rheumatoid arthri...

We present a case report of acute spontaneous knee hemarthosis due to erosion of the nail through the knee joint capsule in a boy, seven months following retrograde flexible nailing for fractured femur. Careful positioning of the location of the insertion site of flexible nails and proper nail tip management are important to avoid this rare late complication.

Twenty-three operations of synovectomy (15 on the knee, 5 on the ankle, and 3 on the elbow) were carried out over a three-year period in 19 patients with severe haemophilia A and B who were followed for an average period of 15 months postoperatively. Short-term evaluation of the results was mainly based on the postoperative incidence of haemarthrosis and on the range of joint motion, which were...

BACKGROUND Hemophilia is a potentially disabling condition as hemophilic arthropathy develops early in life and is progressive, especially in patients treated in an on-demand regime. OBJECTIVE This study aimed to describe the structural joint status and the functional independence score of hemophiliac adults and correlate structural damage with the functional deficits found in these patients....

BACKGROUND We have investigated the behaviour of a newly characterised population of haemarthrosis fluid-derived human mesenchymal stem cells (HF-hMSCs) with titanium (Ti) surfaces. METHODS HF-hMSCs were seeded onto round cannulated interference (RCI; Smith and Nephew) screws or control Ti discs and cultured under pro-osteogenic conditions. RESULTS Electron microscopy showed the attachment ...
