background: osteonecrosis (on) is known to be one of the most disabling complications following corticosteroid (cs) medications. however, evidence regarding risk of asymptomatic prevalence of on among different diseases and the impact of variable steroid regimens are conflicting. we aimed to determine the prevalence of on of femoral head in asymptomatic patients with systemic rheumatic diseases...

The incidence of osteonecrosis was 24% in 248 patients who had received 262 kidney transplants 1971-1982. However, based only on patients at risk, i.e. alive with functioning transplants, the incidence at 1, 3 and 6 years was found to be 13, 27 and 36%; after six years no new cases were found. The relative increase in body-weight at 180 days was predictive as regards risk for osteonecrosis, whi...

Osteonecrosis of the humeral head is an uncommon and slow progressive condition. This condition is difficult to be recognized because its initial symptoms are nonspecific. Simple radiography is the standard tool to stage disease progression. However, plain radiographic findings of osteonecrosis are nearly normal in the initial stage. We report a case of 74 years old female patient who have suff...

introduction: herpes zoster infection (hzi) is a viral disease with painful skin rashes and blisters in a limited area on one side of the body, often in a strip. osteonecrosis with spontaneous exfoliation of teeth in association with hzi of the mandibular nerve is a rare phenomenon. in this report, such an unusual complication of hzi is presented.   case report: the clinical course of a 53-year...

OBJECTIVE The aim of this systematic review was to assess the role of microsurgical reconstruction of the jaws in patients with bisphosphonate-related osteonecrosis, and biological complications after an observation period of at least 12 months. MATERIAL AND METHODS An electronic MEDLINE search supplemented by manual searching was conducted to identify studies reporting data of at least 12 mo...

Our aim was to assess the local extent of osteocyte death in the proximal femur of 16 patients with osteonecrosis of the femoral head. We performed histological examination of the femoral heads and cancellous bone biopsies from four regions of the proximal femur in patients undergoing total hip arthroplasty. A control group consisted of 19 patients with osteoarthritis. All histological specimen...

HIV infected patients receiving antiretroviral therapy (ART) can develop avascular osteonecrosis, 45 times greater than the general population. Avascular osteonecrosis increased in the last few years in patients with HIV infection. The most important mechanisms for avascular osteonecrosis in HIV-infected patients are: changes in bone metabolism, especially osteoporosis correlated with protease ...

BACKGROUND Osteonecrosis of the humeral head is a frequent complication in adults with sickle cell disease. However, little is known about the rate of, and the factors influencing, progression of symptomatic shoulder osteonecrosis in patients with this disease. METHODS Eighty-two adult patients with sickle cell disease and symptomatic osteonecrosis of the humeral head (104 shoulders) were ide...

Background This study aims to evaluate the influence of changes in the teaching contents on medication-related osteonecrosis of the jaw may have on the knowledge and the capacity for practical case resolution about this pathology. Material and Methods A cross-sectional descriptive study was conducted through a survey divided into four sections: degree of means of knowledge acquisition, habitu...
