The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...

BACKGROUND Inappropriate patellar cut during total knee arthroplasty can lead to patellar complications due to increased bone strain. In this study, we evaluated patellar bone strain of a patient who had a deeper patellar cut than the recommended. METHODS A patient-specific model based on patient preoperative data was created. The model was decoupled into two levels: knee and patella. The kne...

Does biting food lead to aggressive behavior? An experimental study is reported where children ages 6-10 (n = 12) were served chicken either on-the-bone or pre-cut in bite-size pieces. When children ate on-the-bone chicken, they exhibited more aggressive behavior than pre-cut, boneless chicken. For example, children were more likely to violate the counselor's instructions by leaving the eating ...

BACKGROUND A high Ki-67 proliferation index (PI) in neoplastic cells is associated with poor survival in mantle cell lymphoma (MCL). We aimed to determine the cut-off values for the Ki-67 PI as a prognostic factor in MCL according to bone marrow findings. METHODS Immunohistochemical (IHC) staining for Ki-67 was performed on formalin-fixed paraffin-embedded biopsy tissues from 56 patients with...

Background: Total knee arthroplasty (TKA) has become the gold standard for definitive treatment of osteoarthritis. One crucial aspect in implantation a TKA is precise orientation femoral and tibial components. The main purpose present study to assess, patients undergoing total replacement, whether difference between planned angulation distal cut obtained postoperative radiological control low e...
