Dr Theokisto is an infectious disease doctor who is trying to find additional help for clinical trials in Texas for my pseudomonas aeruginosa infection in my lungs. I have been fighting for five years. treatment includes repeated antibiotics which don't solve the problem. I need Baylor Scott to help me with this so I may recover my health and get better. Dr Theokisto is taking care of this disease with treatments she has available.
