After resolution of the spinal anesthesia, patients were randomized into 2 groups: "3-in-1" femoral nerve blocks were performed using 30 mL of 0.25% levobupivacaine (Group 1, n = 20) or 0.375% levobupivacaine (Group 2, n = 20). Pain was …

To examine the surgical outcome of 2 different techniques used in the treatment of developmental dislocation of the hip with delayed diagnosis. Materials and methods: The patients were divided into 2 groups based on the technique applied: 21 hips of 18 patients were included in Group 1 and 20 hips of 16 patients were included in Group 2. Initially, all the patients were subjected to femoral osteotomy, shortening, varization and derotation. In Group 1, additionally extra-articular grafting was performed for acetabulum and in Group 2, acetabular osteotomy and extraarticular grafting were performed. The mean age of Group 1 was 8 …

Stenotrophomonas maltophilia is a nosocomial pathogen of increasing importance. Empiric antibiotic therapy for S. maltophilia infection is difficult because the microorganism is resistant to a number of agents typically used for health care associated infections, thus potentially increasing mortality. This study investigates 23 nosocomial pneumonia cases caused by S. maltophilia, the antibacterial sensitivity of the bacterium and the effect on mortality of suitable empiric therapy. Materials and methods: Twenty-three patients with nosocomial pneumonia caused by S. maltophilia between January 2000 and December 2006 at the Karadeniz Technical University Hospital were retrospectively investigated. Results: Suitable empiric therapy was used with 12 …
