  • Missed Opportunities in the Referral of High-Risk Infants to Early Intervention PEDIATRICS Tang, B. G., Feldman, H. M., Huffman, L. C., Kagawa, K. J., Gould, J. B. 2012; 129 (6): 1027-1034

    Abstract

    Using a statewide population-based data source, we describe current neonatal follow-up referral practices for high-risk infants with developmental delays throughout California.From a cohort analysis of quality improvement data from 66 neonatal follow-up programs in the California Children's Services and California Perinatal Quality Care Collaborative High-Risk Infant Follow-Up Quality of Care Initiative, 5129 high-risk infants were evaluated at the first visit between 4 and 8 months of age in neonatal follow-up. A total of 1737 high-risk infants were evaluated at the second visit between 12 and 16 months of age. We calculated referral rates in relation to developmental status (high versus low concern) based on standardized developmental testing or screening.Among infants with low concerns (standard score >70 or passed screen) at the first visit, 6% were referred to early intervention; among infants with high concerns, 28% of infants were referred to early intervention. Even after including referrals to other (private) therapies, 34% infants with high concerns did not receive any referrals. These rates were similar for the second visit.In spite of the specialization of neonatal follow-up programs to identify high-risk infants with developmental delays, a large proportion of potentially eligible infants were not referred to early intervention.

  • Severe Feeding Disorder and Malnutrition in 2 Children With Autism JOURNAL OF DEVELOPMENTAL AND BEHAVIORAL PEDIATRICS Tang, B., Piazza, C. C., Dolezal, D., Stein, M. T. 2011; 32 (3): 264-267

    Abstract

    Leanna, a 10-year-old girl with autism, was hospitalized for severe malnutrition and 20 pound weight loss secondary to reduced intake over 4 months. Her food choices became increasingly restrictive to the point where she only ate certain types and brands of foods. She gradually stopped drinking and developed severe constipation and encopresis. A new behavior of collecting saliva in her mouth and spitting onto napkins also emerged. Vital signs and electrolytes were normal on admission. A nasogastric tube was placed because she refused to eat. A behavior modification plan was implemented that awarded points for completing specific tasks related to feeding, which could later be redeemed for specific rewards, such as computer time. Although her ideal body weight increased from 68% to 75% (due to continuous nasogastric tube feeds), her refusal to eat persisted. Upon further data gathering, the staff learned that she moved and changed schools 5 months ago. She was cared for by either a family friend or paid caregiver while her mother worked. Although she could conduct basic self-care activities without assistance and write and draw at a third-grade level, she functioned cognitively at a 4-year-old level. The behavior plan was modified, breaking the tasks into shorter components with immediate and tangible rewards. She soon began eating small portions of food and spitting less frequently. Toileting was later incorporated into this plan. She was referred to a behavioral therapist in the community to work with her at home and school. Weekly visits with her pediatrician and appointments with a child psychiatrist and dietician were made. Orlando, a 3-year-old boy with autism, was evaluated in the emergency room for lethargy and generalized edema for 6 weeks. The history revealed a restrictive diet of commercial pureed fruit and coconut juice for 2 years. He only ate a particular brand and with specific containers; the limited food intake occurred only with his favorite blanket. He refused to eat other types of food. Outpatient treatments were unsuccessful. On physical examination, he was irritable with an erythematous, scaly rash throughout his body. His hair was thin, coarse, and blonde. He had nonpitting edema in his arms, legs, and periorbital region. The laboratory evaluation was significant for anemia, hypoalbuminemia, and hypoproteinemia. He was admitted to the pediatric service where nutritional formula feedings were initiated through a nasogastric tube. Weight gain was adequate, and the hemoglobin, serum albumen, and protein became normal. The rash improved with zinc supplementation. He was transferred to an inpatient feeding disorders unit where a team of occupational therapists implemented a behavioral modification program to overcome his severe food aversion.

  • Delayed Recognition of Profound Hearing Loss in a 7-Year-Old Girl With a Neurological Condition JOURNAL OF DEVELOPMENTAL AND BEHAVIORAL PEDIATRICS Tang, B. G., Feldman, H. M., Padden, C., Israeli, N., Stein, M. T. 2010; 31 (3): S42-S45

    Abstract

    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.
