Loeb’s Laws of Medicine or Loeb’s Rules of TherapeuticsRobert Frederick Loeb (March 14, 1895-October 21, 1973) was a famous American Physician who provided some very simple common sense approach to treating patients know as:1. If what you are doing is doing good, keep doing it.2. If what you are doing is not doing good, stop doing it.3. If you do not know what to do, do nothing.4. Never make the treatment worse than the disease.The last ‘law’ in present times is often replaced with:“If at all possible, keep your patient out of the operating room.”Or“Above all, never let a surgeon get your patient.”This is a decent reference for this: https://www.ncbi.nlm.nih.gov/books/NBK13258/Dr. Glaucomflecken gives some tips for attending trying to go back to the ICU: https://twitter.com/DGlaucomflecken/status/1238954558140772354?s=20Francis Deng and going back to become an internist: https://twitter.com/francisdeng/status/1245475268158009349?s=20JCI article on using convalescent serum for treating disease: https://www.jci.org/articles/view/138003Human trial of convalescent serum from JAMA: https://jamanetwork.com/journals/jama/fullarticle/2763983 It works!
