How to avoid negative appendectomies: Can US achieve this?

Background: Clinical diagnosis of acute appendicitis is based primarily on symptoms and physical findings. However, diagnosis of appendicitis is not always straightforward. The aim of this study was to demonstrate the diagnostic effectiveness of ultrasonography (US) in these cases in combination with white blood cell count (WBC) and C-reactive protein (CRP) level.

Salmonella identification from foods in eight hours: A prototype study with Salmonella Typhimurium.

Background And Objectives: The significant rise in food borne infections is mainly caused by Campylobacter spp., Salmonella serovars and Verotoxigenic Escherichia coli. As the emerging food borne pathogens cause disease, more studies have been conducted for rapid detection of these pathogens.

[Dennyson-Fulford subtalar extra-articular arthrodesis in the treatment of paralytic pes planovalgus and its value in the alignment of the foot].

Objectives: We evaluated the results of Dennyson-Fulford subtalar extra-articular arthrodesis performed in patients with paralytic planovalgus deformity and its success in realignment of the foot.

Methods: Dennyson-Fulford subtalar extra-articular arthrodesis was performed in 19 feet of 12 patients (5 girls, 7 boys; mean age 97.5 months; range 79-138 months) with paralytic planovalgus deformity.

Measurement of rubidium and xenon absolute polarization at high temperatures as a means of improved production of hyperpolarized (129)Xe.

We report on a rubidium-xenon (Rb-Xe) polarization unit for the continuous production of large quantities of hyperpolarized (129)Xe. The unit includes two diagnostic systems which enable the absolute measurement of both the (85)Rb and (129)Xe polarization in situ and at high temperatures. The Rb diagnostic system allows the measurement of one- or two-dimensional images of the absolute Rb polarization and thus enables the experimental study of light penetration into the optical pumping cell.
