A2 - Appachi, Elumalai Y1 - 2015 N1 - T2 - The Color Atlas of Pediatrics AB - A 9-month-old girl presents to her pediatrician for persistent cough, failure to gain weight and a bulging mass from her rectum. Her mother reports that the girl has had two episodes of “pneumonia” requiring hospitalization at the age of 3 and 5 months. Since that time, she has not gained much weight and is noted to be at the 10th percentile for weight and length. On examination, the patient has course breath sounds and wheezes throughout the lung fields, and has rectal prolapse (Figure 51-1). The pediatrician suspects cystic fibrosis and orders a sweat chloride test, which is 120 mEq/L. This confirms the suspected diagnosis, as a result greater than 60 mEq/L is diagnostic for cystic fibrosis. The family is referred to a comprehensive cystic fibrosis center.
