Traumatic haemarthrosis causing femoral head subluxation.
(76/84)
We report seven children in whom traumatic haemarthrosis of the hip had produced lateral subluxation of the femoral head, which is different from the apparent displacement seen in Perthes' disease. In all seven cases, aspiration of the haemarthrosis allowed reduction of the femoral head, and follow-up for a mean of 14 months revealed no evidence of avascular necrosis of the proximal femoral epiphysis. Traumatic haemarthrosis of the hip in children appears to be a clinical entity which can produce femoral head subluxation. Aspiration and traction is the treatment of choice and can cure the condition. (+info)
Trauma and seronegative spondyloarthropathy: rapid joint destruction in peripheral arthritis triggered by physical injury.
(77/84)
Two B27 positive patients developed peripheral arthritis immediately after a significant musculoskeletal injury. Unlike previously reported peripheral arthritis precipitated by trauma in B27 positive subjects the arthritis was rapidly destructive. (+info)
The probability of death following a fracture of the hip.
(78/84)
All patients 45 years of age and over admitted with fractures of the hip to hospitals in the Atlantic Health Region of Nova Scotia were followed up over a two-year period. Actuarial methods were used to estimate survivorship from the date of fracture in 202 patients.Over-all, it was estimated that only 63.8% would be alive by one year post-fracture. This is 70% of the survival rate expected in the general population of corresponding age and sex. The period of greatest mortality was within the first 12 weeks. Patients surviving to one year could be considered "cured", for after that their survivorship was at least as favourable as that of the "normal" population.Mortality was greatest in males in those 75 years of age and over and especially in patients who were relatively immobilized prior to their fracture. In this "dependent" group the relative survival ratio at one year was only 38%. (+info)
Renal lysozyme levels in animals developing Proteus mirabilis-induced pyelonephritis.
(79/84)
In animals developing experimentally induced unilateral pyelonephritis, both the infected kidney (IK) and the contralateral noninfected kidney (NIK) showed an immediate increase in renal lysozyme activity of about 5 days' duration after the unilateral injection of viable Proteus mirabilis into the renal cortex. Lysozyme activities of the NIK were consistently higher than those of the IK. This initial increase was followed by a second increase which lasted throughout the period of observation (17 days), and enzyme activities of the NIK were consistently higher than those of the IK. In saline punctured kidneys of control animals, both the saline punctured kidney (SP) and the non-saline punctured kidney (NSP) showed only the immediate increase in renal lysozyme activity, which persisted until the SP was completely healed. These enzyme activities were less than those observed in the infected animals, but the response of the NSP was greater than that of the SP. Trauma not directed to the kidney does not produce a similar response of renal lysozyme. The elevated renal lysozyme of the NIK could not be shown to protect it from bacterial infection. (+info)
Transient synovitis of hip. A virological investigation.
(80/84)
Virological studies in 17 children with transient synovitis of the hip did not confirm the suggestion that this is caused by a viral infection. Minor trauma is thought to be a more likely cause. (+info)
