User :   My son smelled distinctly like maple syrup once with no other symptoms. Should I be concerned about intermittent MSUD?
Doctor :   Hi
User :   Hi
Doctor :   I am Dr.XXX here
Doctor :   Let me read your query
Doctor :   Ok
Doctor :   May I know his age?
User :   He is now 5 months. I noticed the distinct smell 1 time when he was around 8 weeks old. But I recently brought him to the dr because I thought his urine smelled very strong.
Doctor :   Ok
Doctor :   Was it tested?
User :   They sent the urine to the lab and said they won't have results for a week. It was not tested when he had the distinct maple syrup smell though.
Doctor :   Ok
Doctor :   Also for that serum Leucine will have to be tested
Doctor :   to confirm MSUD
User :   His newborn screenings were both normal so he doesn't have the classic version for sure but i'm worried about intermittent
Doctor :   Ok
Doctor :   if the serum leucine levels are normal then there is nothing to worry
User :   But with no other symptoms, can a maple syrup smell ever be normal?
Doctor :   urinary infections can also produce smell
Doctor :   so that also should be thought of
User :   UTI was negative
Doctor :   as a differential diagnossi
Doctor :   fine
User :   But with no other symptoms, can a maple syrup smell ever be normal?
Doctor :   If it is confirmed with the blood test that there is no problem
Doctor :   then nothing to worry
User :   Intermittent can only be detected during an active period I've read though so with that one time being such a distinct smell I'm concerned.
Doctor :   thats right
Doctor :   but with one time, no diagnosis can be made
Doctor :   Did you talk about this with your pediatrician?
User :   Yes, he had blood work done on Monday. I'm still waiting on the results. But I'm concerned that even if they come back normal that I should still be on the lookout due to that one time at 8 weeks old. His urine smell now is strong but to me it is not maple syrupy like he smelled that one time
Doctor :   As per my knowledge, I dont see any problem with it
Doctor :   it should be normal if the reports come out fine
Doctor :   for further guidance on it
Doctor :   you can consult our Pediatrician
Doctor :   who can give the additional info
Doctor :   about the future prognosis
User :   ok, how do i go about doing that?
Doctor :   I shall give the link for the same
