Effect of Radial Nerve Release on Lateral Epicondylitis Outcomes: A Prospective, Randomized, Double-Blinded Trial.

Purpose: The purpose of our study was to examine the result of lateral epicondylitis surgery with and without posterior interosseous nerve release.

Methods: We conducted a prospective, randomized, double-blind single-center clinical trial in 54 patients treated surgically for lateral epicondylitis, without any EMG or imaging sign of compression of the posterior interosseous nerve at the arcade of Frohse. The patients were equally divided into intervention (supplemental radial nerve release) and control groups (no radial nerve release).

Expression of lineage markers using real-time quantitative polymerase chain reaction (RT-qPCR) in normal and in leukemia bone marrow.

Background: The study of lineage markers by real-time quantitative polymerase chain reaction (RT-qPCR) at diagnosis enables differentiation between acute myeloblastic leukemia, B- or T-lineage acute lymphoblastic leukemia, without cell sorting. Our objective was to assess the relationship between protein expression and the amount of lineage marker mRNA in acute leukemia samples and to determine whether four lineage markers could be used to differentiate between normal and acute leukemia bone marrow (BM) without cell sorting.

Methods: Quantification of the mRNA of CD19, CD79a, CD3e, and myeloperoxidase was performed by RT-qPCR on 130 acute leukemia BM samples at diagnosis and on 20 BM samples from healthy donors, without cell sorting.

Patellar fracture following combined proximal and distal patella realignment.

The authors present a case of a proximal avulsion fracture of the patella two months after a combined proximal and distal realignment operation. Devascularisation of the patella due to the combined technique was considered the main pathogenic factor. Treatment with open reduction and transosseous fixation was successful.

Are bone autografts still necessary in 2006? A three-year retrospective study of bone grafting.

Autograft is considered as the gold standard in bone grafting. However, the development of tissue banks has allowed for a wider use of bone allografts, with good results. Demineralised Bone Matrix (DBM) and recombinant human Bone Morphogenetic Proteins (rh-BMP's) were also introduced to replace the time-honoured autograft.
