Kelly is a 7-year-old girl with a complex medical history including asthma, mild spastic diplegia, and seizure disorder that is controlled with carbamazepine. She had a significant receptive and expressive language impairment and milder delays in gross and fine motor skills. Kelly is currently repeating first grade in a self-contained classroom; she receives speech, occupational, and physical therapy. At the 7-year-old well child visit, her mother is worried about Kelly's poor progress in school, and she expresses concern about her daughter's hearing. Her pediatrician observes that Kelly is withdrawn, uses minimal language, and is fearful of the examination.Kelly was born full-term by Cesarean section because of placental abruption. She was in the neonatal intensive care nursery for 2 weeks with metabolic acidosis because of acute tubular necrosis. One day after arriving home, she had a cardiopulmonary arrest followed by emergency open-heart surgery for critical pulmonary hypertension. Her postoperative course was significant for renal failure, extracorporal membrane oxygenation, ventilator dependency, tracheostomy, and gastrostomy. By 3 years of age her medical condition stabilized, and the tracheostomy and gastrostomy tubes were removed.A review of Kelly's previous audiological tests revealed a failed otoacoustic emission test at 5 months. An auditory brain stem response test at 8 months recorded normal hearing in the right ear. At 4 years, behavioral audiometry was attempted but not completed because Kelly cried throughout the session. At 5 years, testing with ear inserts showed normal hearing bilaterally.Because of the concerns raised by Kelly's mother at the pediatric visit, she was referred to audiology for a reevaluation. Testing at this time revealed moderate to profound sensorineural hearing loss in both the ears, which was confirmed on subsequent examinations. Kelly was promptly fitted for hearing aids. Her individual education plan was changed to reflect the diagnosis of hearing impairment, and hearing services were implemented in the classroom. On a recent follow-up visit, Kelly was talkative, engaging, and cheerful.

Wolcott-Rallison syndrome is a rare disease presenting with insulin-dependent diabetes mellitus (DM) before 6 months old, skeletal dysplasia after 6 months old, and liver failure. Other manifestations are renal failure, microcephaly, epilepsy, central hypothyroidism, neutropenia, and dental and dermal problems. The cases were 2 patients from 2 different states of Iran (Khoozestan and Fars) who had developed DM before 6 months old. The first one was a 7-month-old infant who was healthy; in the genetic study (screening), autosomal recessive pattern and novel deletion in EIF2AK3 were reported; her sister had died at 5.5 years old due to diabetic ketoacidosis (DKA) that was associated with liver and renal failure. The second patient had developed DKA at 45 days old, which was associated with mild acute tubular necrosis and abnormal coagulation tests at onset clinical presentation, which were then resolved. He was treated with insulin, and at follow-up, the laboratory data are normal; in the genetic study, EIF2AK3 nonsense homozygous mutation was diagnosed. Genetic study of patients with insulin-dependent DM before 6 months old, especially those with DKA and associated with or without other disorders; attention to novel deletion of in EIF2AK3 gene; screening for skeletal dysplasia after 1 year old; and renal, liver, pancreatic, and thyroid function tests are recommended.
