Ann: Remestemcel-L for COVID-19 MIS-C published in Pediatrics, page-161

I think you overstepped there. First of all, this is a case report. You have been an ER doctor long enough to know that case reports are very common in the medical field. Although case reports are not clinical trials, they are very important in driving the medical field forward and discover new treatments. If you are only allowed to treat patients based on the use of medications for their approved conditions, what are you going to give to patients with an unknown diagnosis or idiopathic diseases?

As far as I know, Doctors do 'experiments' on real patients based on their best judgement and experiences and use treatments that Do not harm the patients. So it is better for all doctors to publish case reports, just like the authors of this paper. All they are saying is, MSCs look interesting and so far the result is encouraging (here is the evidence), one should look into it further.
