For those who do not know our duet of internist, EL and RK both used to be physician of the same ward. Two particular stories between them are worth mentioning:
*********************
(EL met RK at the nursing station. The latter had just finished seeing a patient who was referred by the professor of rheumatology for a neurologist's opinion.)
EL: What's wrong with my patient?
RK: I'm not sure. I need some time to sort it out.
EL: What are you going to do for her now?
RK: I don't know. I need to think it over before making a decision.
EL: The condition is critical. You've got to make the decision now.
RK: Em... OK, I decide... to make the decision tomorrow.
*********************
(Same scenario. Nursing station again. RK just finished seeing another patient referred by the rheumatologist.)
EL: What's wrong with my patient?
RK: I'm not sure. I need some time to sort it out.
EL: What are you going to do for her now?
RK: Let's do a CT brain.
EL: CT brain is quite useless in this situation.
RK: Let's do an MRI.
EL: MRI is equally useless.
RK: Let's do lumbar puncture and EEG.
EL: These are also useless.
RK: Yes, but, if we put all useless things together, they may become useful.
This is what I call intelligence.
