We did manage to carry out a successful three-week reconnaissance of Indochina in May. Christiana Hospital turned out to have its own travel medicine practice, so there was no need to return to Johns Hopkins. The travel doc, apprised of my situation, made no attempt to dissuade me from making the trip. She provided us with the necessary vaccinations (e.g. Hepatitis A and typhoid fever), as well as with some prophylactic anti-malaria pills (taken starting before the journey and continuing for a week after returning) and antibiotics (Cipro) for "traveller's diarrhea", should it occur. In the event, no one got hurt or ill on the trip, and a good time was had by all.
The biopsies on the tissue samples taken during the recent endoscopy turned up nothing. The GI doc is standing by his diagnosis of mild, "non-specific" (code for "we don't know where this is coming from") gastritis, but otherwise apparently has nothing to offer, at least based on the results of the endoscopy. The Xifaxan he had me try impacted my symptoms not one iota. I may follow up, but based on twenty years of on-again-off-again experience with GI specialists, it wouldn't be with any elevated hopes.
