One hundred twenty-two patients with tuberculous or pyogenic spondylitis were investigated retrospectively. Patient histories, laboratory tests, and radiographic findings were compared statistically between the two groups. Significant differences were calculated for the interval between onset of symptoms and diagnosis, erythrocyte sedimentation rate, mean(More)
Erb:YAG and Hol:YAG laser ablation rates of fibrocartilage and nucleus pulposus were measured in vitro simulating clinical conditions. After ablation macroscopic and microscopic appearance of the ablation site was investigated. Hol:YAG and Erb:YAG laser mean ablation rates increased almost linearly with rising energies, showing higher total ablation rates(More)
The aim of the current study was to reveal whether 7 days of indomethacin treatment sufficiently prevents heterotopic ossification after cementless total hip arthroplasty. One group received indomethacin for 14 days (n = 102), and the second for 7 days (n = 99) after cementless total hip arthroplasty. At followup 1 year postoperatively, the average Harris(More)
UNLABELLED Tourniquets commonly are used during total knee arthroplasties to reduce intraoperative blood loss, despite their various side effects. The goal of this study was to determine whether tourniquet use could be avoided using epinephrine-augmented hypotensive epidural anesthesia during a total knee arthroplasty without negative effects on(More)
Subcutaneous recombinant human erythropoietin (rHuEpo) treatment of renal anemia was performed in four boys and eight girls on CAPD, aged 0.8-12.5 (mean 7.4) years. In contrast to previous studies, our therapeutic goal was not set with a hematocrit of 30% but with full correction of anemia. Following a maximum weekly rHuEpo dosage of median 120 (range(More)
87 patients were treated for metastatic disease of the spine between 1970 and 1992. In the majority of the patients anterior decompression and stabilization was performed. The posterior approach was chosen only in case of predominant infiltration of the dorsal parts of the vertebra or in case of inaccessibility of the tumor via an anterior approach. The(More)
Sixty-nine male Sprague Dawley rats were divided into three groups of 23 animals each and osteotomies were performed in group 1 with a power saw, in group 2 with the Erb:Yag laser, and in group 3 with the Hol:YAG laser. Two animals of each group were sacrificed 1 week, 4, 8, and 12 weeks after operation for histologic investigation, and five animals of each(More)
The paucity of epidemiologic data, and the previous impression of high incidence of cerebrovascular disease in Brazil, made us elaborate a prospective institutional study in Joinville, Brazil, with objective of identifying first and recurrent episodes in stroke. This study occurred from March 1995 to March 1996. We evaluated during the first episode of(More)
Ho:YAG, Nd:YAG, and Erb:YAG laser ablation of Polymethylmethacrylate (PMMA) was investigated under in vitro and simulated clinical conditions. Ablation rates were measured for all lasers and after ablation, macroscopic and microscopic appearance of the ablation site was investigated. The mean ablation rates of the Erb:YAG, Ho:YAG, and Nd:YAG laser increased(More)
OBJECTIVES Recent data indicate an increased vascular reactivity due to an overactivity of the sympathetic nervous system in women with pre-eclampsia. We therefore evaluated whether this increased vascular reactivity can be detected prior to the clinical manifestation of preeclampsia by the use of a physiological stimulus.
