Comparative StudyA comparison of propofol target controlled infusion-based and sevoflurane-based anesthesia in adults undergoing elective anterior cervical discectomy and fusion.
The target controlled infusion (TCI) of propofol with fentanyl facilitates easy titration of the depth of anesthesia, and thereby may improve the quality of anesthesia. The aim of this study is to investigate if propofol TCI-based anesthesia is practical for anterior cervical discectomy and fusion (ACDF), one of the most common surgical interventions in spine procedures, when compared with sevoflurane-based anesthesia with respect to the quality of anesthesia. Patients were classified into two groups according to the anesthesia regimen of maintenance of anesthesia with fentanyl and either propofol TCI (group FP) or inhalational sevoflurane (group FS), respectively. ⋯ No differences in average length of intensive care unit (ICU) stay and hospital stay were noticed. However, opioid consumption and blood loss during the operation for patients in group FP were significantly higher than those of patients in group FS (551.28 ± 193.98 vs. 446.86 ± 177.15 μg, p = 0.005; 52.06 ± 58.25 vs. 28.33 ± 40.74 mL, p = 0.019, respectively). In these adult patients undergoing ACDF, propofol TCI-based anesthesia appears to be as efficacious as sevoflurane-based anesthesia but consumed more fentanyl and experienced higher blood loss.

Usefulness of admission hematologic parameters as diagnostic tools in acute pulmonary embolism.
The purpose of this study was to determine the role of red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) in the diagnostic phase of acute pulmonary embolism (PE). We screened 248 consecutive patients who were admitted to the emergency service with PE foremost in the differential diagnosis. Based on spiral computed chest tomography, the patients were divided into two groups. ⋯ In multivariate logistic regression analysis, troponin I, D-dimer, high-sensitivity C-reactive protein, and RDW were found to be independent predictors of PE [odds ratio (95% confidence interval) respectively: 5.208 (2.534-10.704), 1.242 (1.094-1.409), 1.005 (1.000-1.010), 1.175 (1.052-1.312)]. In receiver operating characteristic analysis of the patients in the study, RDW >18.9 predicted acute PE with a sensitivity of 20.7% and a specificity of 93.4%. In conclusion, RDW can be considered useful as a diagnostic measure for patients with suspected acute PE.

Utilization of 18F-FDG PET/CT as a staging tool in patients with newly diagnosed lymphoma.
The aim of this study was to investigate the role of 2-fluorine-18-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) in the initial staging and prediction of bone marrow involvement in patients with newly diagnosed lymphoma. A total of 185 patients with newly diagnosed lymphoma were enrolled. All patients received PET/CT and bone marrow biopsy as part of a staging work-up. ⋯ PET/CT had a high PPV for aggressive B-cell lymphoma with diffuse bone marrow FDG uptake and high NPVs for excluding bone marrow involvement in aggressive B-cell lymphoma and Hodgkin's lymphoma. Bone marrow biopsy may be omitted for the above subgroups of patients with medical conditions not suitable for this procedure. For patients with indolent B-cell lymphoma, bone marrow biopsy is still an indispensable procedure for staging.
