In this study we validated intraoperatively the analysis of polymorphonuclear leucocyte frozen sections for diagnosis of infection in hip and knee revisions. Between 1996 and 2002 we examined sections and cultured periprosthetic tissues in prosthetic revision in 170 cases, including 146 cases (83 hips and 63 knees). We assessed sensitivity (SE), specificity(More)
The optimal management of pyogenic discitis is not agreed on. We conducted a retrospective, cross-sectional, observational study in which all patients with discitis who attended Hospital San Carlos Madrid from January 1999 to January 2009 were included. We identified 108 consecutive adult patients with infectious discitis. There were 49 men and 59 women(More)
Pathological fractures of the long bones are common complications of metastatic disease; however, the outcome of different surgical techniques for the treatment of these fractures has not been clearly defined. The aim of this study was to evaluate differences in prophylactic and therapeutic intramedullary nailing in femoral metastasic implants. Sixty-five(More)
Periprosthetic fractures (PPF) have become a frequent complication of total hip and knee replacements with rates up to 15 % in major registries. Other artificial articulations such as the shoulder and the elbow, although less frequently concerned, are not immune to this complication. This observation is related to the increased number of procedures(More)
A series is here reported of 30 hips from 21 patients with the diagnosis of avascular necrosis in different stages (Ficat 0 = 1, I = 4, II = 13, III = 10, IV = 2). Patients underwent external electro-stimulation by means of a electromagnetic field generator, and results were evaluated by NMR at three-month intervals. Lesions were categorized by NMR: < 25%,(More)
AIM To develop a novel validated method for the isolation of Bifidobacterium animalis ssp. lactis BB-12 (BB-12) from faecal specimens and apply it to studies of BB-12 and Lactobacillus rhamnosus GG (LGG) recovered from the healthy human gastrointestinal (GI) tract. METHODS AND RESULTS A novel method for isolating and enumerating BB-12 was developed based(More)
A further case of juxta-cortical chondroma in the first finger-ray of a 61-year-old woman. Periosteal chondroma is an extremely rare benign tumor. Only 34 cases can be found in the literature. The tumor is cured with surgical removal.
