Now I frankly must disagree with this statement.
If you were living in the 1950's as transistors were replacing vacuum tubes would you advise someone to become a vacuum tube engineer if they loved it regardless of job market trends?
Would you advise someone to become a meter reader if they loved it even though these jobs are going away as the ability to read meters remotely multiplies?
Would you advise someone to become a medical transcriptionist if they love it even though voice recognition software is becoming more widespread?
Would you advise someone to go into nuclear medicine which has been decimated as V-Q scans have fallen out of favor and the job market for straight nuclear medicine docs is practically non-existent as radiologists are reading many nuc scans?
Syphilis is a complex systemic illness with protean clinical manifestations caused by the spirochete Treponema pallidum. It holds a special place in the history of Western medicine because of its earlier prevalence and its variable clinical presentations, for which it earned the epigram the great imitator or the great impostor.
The first medical specialists treating this disease were called syphiliologists and they established special clinics. In addition, one of the first specialized medical journals appeared, the American Journal of Syphilis, Gonorrhea and Venereal Disease http://www.mdconsult.com/das/book/body/149159662-2/0/1259/1890.html
Would you advise someone to specialize in treating only syphilis patients today?
