It's not about diagnosis it's about keeping our kids healthy. Has your children been with this care center through this previous winter with infections that turned to pneumonia? My son has S1235R and G551D. He sees Dr. Marie Egan at Yale. I think it is worth your while to come down to see her for a consult. You should be treating your children more aggresively. What 's the harm? I really wonder with your dr's motivation is? Why would you not want to arm a parent with how to do CPT? Is he looking to minimize the nubmer of CF patients he follows? My husband and I wonder if statistically speaking it would look better for the center to give a CRMS diagnosis than an CF diagnosis. Do yu know if CRMS cases are entered into the registry? I really wonder if late diagnoses are going to become like the ***** child of the cf world where no one wants them (like ceapcia cfers seeking transplant) since the statistical outcomes are so much poorer. It sounds like your kids cases are quite advanced. I'm sorry. Please do smething for them. Call Dr. Egan tommorrow. Or something.
