To determine the diagnostic accuracy of Kernig's sign, Brudzinski's sign, and nuchal rigidity for meningitis, 297 adults with suspected meningitis were prospectively evaluated for the presence of these meningeal signs before lumbar puncture was done. Kernig's sign (sensitivity, 5%; likelihood ratio for a positive test result [LR(+)], 0.97), Brudzinski's sign (sensitivity, 5%; LR(+), 0.97), and ...

The possible contribution of computed tomography (CT) in the management of patients with solitary pulmonary nodules (SPNs) or masses was reviewed retrospectively in 65 patients undergoing fiberoptic bronchoscopy (FOB). Nodules were evaluated by size, location, surface contour, and the presence in cross-section of a bronchus leading to or contained within the nodule or mass, a "positive bronchus...

A positive sonographic Murphy sign, the presence of maximal tenderness elicited over a sonographically localized gallbladder, has been reported to be a helpful adjunctive finding in patients with proven acute cholecystitis who are evaluated with ultrasonography. We evaluated 200 patients with right upper quadrant pain, thought to be acute cholecystitis. Results of ultrasound examinations and su...

An important argument in favor of the encyclical theory of the epistle to the Ephesians is based upon the peculiarities found in the epistle itself. Yet these unusual features (e.g., the lack of personal greetings, the unusual statements in 1:15, 3:2, and 4:21, etc.) can all be satisfactorily explained in the light of an original Ephesian destination. After an examination of early scribal habit...

Markov fluid models with fluid level dependent behaviour are considered in this paper. One of the main difficulties of the analysis of these models is to handle the case when in a given state the fluid rate changes sign from positive to negative at a given fluid level. We refer to this case as zero transition. The case when this sign change is due to a discontinuity of the fluid rate function r...

In the early events of human immunodeficiency virus type 1 (HIV-1) infection, immature dendritic cells (DCs) expressing the DC-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) receptor capture small amounts of HIV-1 on mucosal surfaces and spread viral infection to CD4(+) T cells in lymph nodes (22, 34, 45). RNA interference has emerged as a powerful tool to gain insigh...

Background: Development of thoracic ultrasound made it a useful tool for diagnosing respiratory disorders. But it has been rarely described in literatures about the accuracy of sonographic signs specific to pneumothorax. We studied the sonographic findings of pneumothorax in children and examined the patients with chest pain and/or dyspnea in our pediatric emergency department to determine the ...
