Hi L.,
I'm a second year medical student and I happen to be studying both pneumonia bacterias and probiotics right now. I went to a talk today about how they are starting to use probiotics even in the hospitals now, with great success, so I would suggest if your child has taken any sort of antibiotics, that she be given a good quality probiotic like Jarrow for Kids or something equivalent. Yogurt is good, however dairy products can increase mucus production and a good probiotic formula will deliver many more organisms, which can have a preventative effect. In addition, there are many bacteria that are becoming quite resistant to many antibiotics, and these are out in our communities now in greater and greater quantities. Make sure that they do a full sputum culture with gram staining and drug sensitivity testing. It might cost a bit more, but it is well worth it if your child is having a remission to figure out exactly which organism is causing the disease and what drugs will be effective on it. If your doc doesn't take this seriously, or it isn't going anywhere, get another opinion. Find a recommendation from another parent if possible on their doc that they LOVE! Finally, the person who suggested it could be structural, like trachea shape or a collapsed lung have valid points and any excellent physician is going to be concerned about these possibilities as well. Be your and your child's best advocate, don't hesitate to ask questions, and if your doctor's office isn't a comfortable place to have discussions and ask questions, you should try to find another doctor anyway. Health care is too important, and everyone needs to be working together as a team to find the best solutions. Best of luck to you!
