Dear Eleanor,

You are right about not relying on Pubmed filters if you are looking for ALL you can find on a subject. 
In this case, the number of results is so low, that the best approach is not to limit according to study type, and just let your researcher screen all the results manually. 
This can be done very quickly for such a small amount of references.

In general, a more inclusive filter for PUBMED would be:
"Case reports" or "case report" or "case study" or "case studies" or "case history" or "case histories"
But, you can still miss some references. If you have a platform that allows for adjacency, you can do something like "case$ adj2 report$" OR ...etc.

And if it's important to get ALL relevant case reports on this subject, PUBMED is not enough. 
For example, I found the following reference in EMBASE:

A cause of pancreatitis in a commonly used antibiotic: Metronidazole-induced pancreatitis
Patel K., Shah S., George T.
American Journal of Gastroenterology (2017) 112 Supplement 1 (S1522).

Seems relevant, but does not appear in PUBMED....

Subject: CHAT: Question re establishing search parameters

Patron needs ALL the case reports on metronidazole-induced pancreatitis. I did a simple search, choosing "Case Reports" as a filter. 12 were retrieved. BUT.... I then opened one of them up, and went to the "similar articles" portion and clicked on one that looked likely. It is indeed a case report on this topic, making my current total 13.

But here's my question: how can I structure the search so that it grabs those articles that don't have Case Report in the title? I cannot see me going through each abstract, trolling for possibilities like I did for the 13th article. There must be a way to increase the retrieval via search terms, no? Thanks so much in advance. I hope I'm making sense!
