A pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae, which is also called the pneumococcus. S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. However, it is also a cause of significant disease, being a leading cause of pneumonia, bacterial meningitis, and sepsis. The World Health Organization estimates that in 2005 pneumococcal infections were responsible for the death of 1.6 million children worldwide. Infections
Pneumococcal pneumonia represents 15%–50% of all episodes of community-acquired pneumonia, 30–50% of all cases of acute otitis media, and a significant proportion of bloodstream infections and bacterial meningitis.As estimated by WHO in 2005 it killed about 1.6 million children every year worldwide with 0.7–1 million of them being under the age of five. The majority of these deaths were in developing countries. Pathogenesis
S. pneumoniae is normally found in the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. It can be found in higher amounts in certain environments, especially those where people are spending a great deal of time in close proximity to each other (day-care centers, military barracks). It attaches to nasopharyngeal cells through interaction of bacterial surface adhesins. This normal colonization can become infectious if the organisms are carried into areas such as the Eustachian tube or nasal sinuses where it can cause otitis media and sinusitis, respectively.
Videx, Inc. is a Corvallis, Oregon manufacturer of computer hardware such as access control products and data collection terminals. Its initial success came with the first release of the $345 Videoterm (80 column) display card in March 1980 and the $149 shift and custom keyboard mapping Enhancer II terminal card in November 1981, both for Apple II computers. Later, in 1984, it released its $379 UltraTerm expansion card boasting high-definition 96-pixel characters and up to 128 × 32 character display. These products became obsolete when Apple released the Apple IIe with most of the 80-column card hardware built-in - only a much simpler and cheaper RAM card was then required. Videx also produced software, including Desktop Calendar for the Apple Lisa. References
