My youngest son, who is now 10 months old, has been sick off and on for several months now (actually since September). We have been in the hosptial with him twice over a two month time frame (in Oct and Dec). The pediatrician who was in charge of his care in the beginning stated that "it is just the weather". The first time he was hospitalized was for a viral infection (that they could never figure out what it was) and the second time was for RSV (confirmed, test was performed). We have been on the nebulizer(breathing issues, such as wheezing, panting, chest congestion, etc..X-rays were fine) and--Pulmicort and Xopenex--since October and we have been back and forth to the doctors office since the hospitalizations. I got fed up last week. The doctor had him on an antibotic (Omnicef) for twenty days and another refill at the pharmacy to pick up when he is finished with that antibotic, not to mention a fever for six days. I know that cannot be good. He has not had symptoms of any other condition ear, nose, throat is clear...but he has had diarrhea for longer than a week which may had been caused by the antibotic but he has been off of it for a week and still has diarrhea. I cannot really described the stool, his always has an odor. He also has not been eating good. Well, I decided to seek another pediatrician's advice and met with them last week. She mentioned Cystic Fibrosis but could be anything, he is in the 10% for growth but still a petite thing. Well, to make a long story short, she referred us to a Pediatric Pulmonologist for testing. The Pulmonologist also stated Cystic Fibrosis or childhood ashtma, etc...So we took the following test at the hospital: Barium Swallow, lab test...IGA, IGM, IGE, and IGG and then they took blood to be sent to Utah for the Genetic mutation for cystic fibrosis--32 mutations (from reading i assume this is the genetic test). We have not received the results yet because they stated it could take up to two weeks, but what do you all think? I have no idea if my husband or I are carriers. This does not run in my family. I have a daughter who is five and a son who is three and they are both failure to thrive but other than that, perfectly healthy. I was worried because the pulmonologist did not do a sweat test just blood test, will that still give me good results? Or~do you think this is just him getting over RSV and maybe a common cold too? Or is it just the weather? So many questions, just a very concerned mother seeking answers. The pulmonologist seemed to think that there is something there which caused the RSV. Just to let you know~he also had an infection at birth that they could not determine which required him to have antibotics in the level 2 nursery. Help!!!!! One more question if someone can help, his chest congestion and wheezing does not happen every day, just every now and then. Should I be concerned or am i over reacting?
