i'm doing a case study at a free clinic and i have a 53 yearold overweight white man with several obvious problems. his feet are crackedand blistered and he has 3 infected toenails. he says he has been homeless forvarious periods during the last 10 yrs. he has seeping sores in the folds ofhis wrists and under his arms. his gums are bleeding. he has been greatlyconfused over the last 8 months and its getting worse (his purpose for comingto the clinic). he has episodes of ranting and raving and he reports"feeling crazy" and being very scared. upon questioning his healthhistory he reveals very little, saying his memory is bad but he talks a lotabout his past sexual exploits. i know mental illness is comon in homeless people. i believethat some of this mans neural symptoms are caused by syphilis - general paresis(a form of neurosyphilis). it is causedby the gram negative bacteria, treponema pallidum. if his blood test comes backpositive, can this man transmit the disease and why/why not? should he be treated with antibiotics andwhy/why not? what other infectious disease should he now be tested for if hisblood test came back positive?
