The biggest insight from years of practice is that if you put your heart and soul into the patient, you will have a different outcome. There was a case of a patient with fever to be investigated, persistent high fever, and parotid enlargement, chest and abdominal fluid, low blood count, the patient is a young woman, consider the infection, for an orofacial cellulitis, given advanced antibiotic treatment for 7 days after the infection is controlled, but the appearance of neurological symptoms, very confused, the last doctor suspected that it is an autoimmune system disease, checked the autoantibodies and other diagnoses of lupus erythematosus, and finally applied hormones to control the disease. Finally the disease was controlled by applying hormones. A doctor should learn from his patients and see them more often.
