If you are faced with the problem of an unrecognized diagnosis or with a disease that is difficult to treat, the book by O. I. Eliseeva will certainly be of interest to you. It contains letters from people suffering from diseases before which orthodox medicine turned out to be powerless, people desperate to overcome their ailment, and who turned to the famous doctor as a "last resort." Olga Ivanovna Eliseeva, a practicing doctor of the highest category, has been giving the joy of recovery to thousands of patients for many years. Every day she receives dozens of letters in which people ask for help. Being unable to personally help everyone in need, Olga Ivanovna decided to write the book "Encyclopedia of Unrecognized Diagnoses." Using readers' letters as a kind of anamnesis, she makes presumptive diagnoses, illustrates them with clinical examples from her richest practice, and makes recommendations on what research should be done to recognize the true causes of the disease, make a correct diagnosis, and finally get rid of annoying ailments.
