3 yo child with recurrent pneumonia

[usmlelover]

3 yo child with recurrent rt. lower lobe pneumonia.Growth parameters---25th percentile, & developmentally appropriate for his age.
PMH----ear infection at 18 months & gastroenteritis at 2 yrs of age.
Which of the following conditions is most likely responsible for this pt.'s disease?
1.Primary B- or T- cell immunodeficiency
2.Cystic fibrosis
3.Chediak higashi syn.
4.Congenital lung abnormality
5.Foreign body aspiration

[jamesdonkey]

The answer is foreign body aspiration

Foreign body aspiration is the most common cause of recurrent pneumonia in an otherwise healthy 3 yo child. Becoz of the lung's anatomy,the rt.side is more common for aspiration.
Immunodeficinecy disorders........recurrent infections by oppurtunistic organisms+failure to thrive
Cystic fibrosis....failure to thrive, malabsorption,clubbing
Chediak higashi.....recurrent infections of skin & mucous membranes & RS, albinism.
Congenital lung abnormalities......present at a much earlier age.

i think this child has cystic fibrosis b/c he has ear infections and gastroenteritis too that is not explained by foreign body.
