Imagine:  you are the single provider manning a rural clinic in Northern Tanzania along the shore of Lake Victoria.  You are one of only a handful of physicians in the entire region and you have minimal access to diagnostics or therapeutics.  Your clinic does not have any power.   Your diagnostics include:  urinalysis, urine pregnancy, CBC and rapid tests for HIV, syphilis, and malaria.  You have 2 nurses, one of whom acts as a translator (from Swahili to English).  You are armed primarily with your intellect, knowledge of local disease processes, and your keen sense of intuition.
