Thanks @SAM_2014 So are you still waiting medical result for both the categories?We did medical for visitor and got furtherance letter for one of my parent.
Mean while got request for PGP medical and informed visa office about extension medical... and they replied that once my parents gets passed for visa extension medical then they will look into it and will confirm later that its acceptable for PGP catg or not ... so in hanging situations for both medicals.
Best wishes!
