Tick bite fever in South Africa

Tick bite fever has been a constant feature of the South African medical landscape. While it was recognised many years ago that there was a wide spectrum of clinical severity of infection, only recently has it been established that there are two aetiological agents, with different epidemiologies and clinical presentations. Rickettsia conorii infections resemble the classical Mediterranean spotted fever (fièvre boutonneuse), and patients are sometimes at risk of severe or even fatal complications. On the other hand, African tick bite fever is a separate entity caused by Rickettsia africae and tends to be a milder illness, with less prominent rash and little tendency to progress to complicated disease. Irrespective of the agent, the treatment of choice for tick bite fever in South Africa remains doxycycline or tetracycline, and the role of macrolide and quinolone antibiotics is still unclear, or at least restricted.

Lessons learned applying CASE methods/tools to Ada software development projects

This paper describes the lessons learned from introducing CASE methods/tools into organizations and applying them to actual Ada software development projects. This paper will be useful to any organization planning to introduce a software engineering environment (SEE) or evolving an existing one. It contains management level lessons learned, as well as lessons learned in using specific SEE tools/methods. The experiences presented are from Alpha Test projects established under the STARS (Software Technology for Adaptable and Reliable Systems) project. They reflect the front end efforts by those projects to understand the tools/methods, initial experiences in their introduction and use, and later experiences in the use of specific tools/methods and the introduction of new ones
