Developmental-behavioral pediatrics (DBP) subspecialists care for children with complex neurodevelopmental and behavioral health conditions; additional roles include education and training, advocacy, and research. In 2023, there were 1.0 DBP subspecialists per 100 000 US children aged 0 to 17 years (range 0.

Background: Down syndrome is a chromosomal disorder with considerable neurodevelopmental impact and neurodegenerative morbidity. In a pilot trial in young adults with Down syndrome, memantine (a drug approved for Alzheimer's disease) showed a significant effect on a secondary measure of episodic memory. We aimed to test whether memantine would improve episodic memory in adolescents and young adults with Down syndrome.

Objective: To examine and define the evolving subspecialty of developmental-behavioral pediatrics (DBP) by analyzing workforce surveys presubspecialty and postsubspecialty certification.

Methods: In 2015, an electronic workforce survey was sent to the members of the American Academy of Pediatrics Section on DBP and Council on Children with Disabilities and the Society for DBP. Answers from the 1998 survey for respondents with subspecialty fellowship training were compared.

Background: It is unknown how insurance status affects elements of evaluation at developmental behavioral (DB) pediatric sites.

Objective: To compare DB referrals, evaluation, and treatment for children with Medicaid and private insurance.

Design/methods: Fifty-six developmental behavioral pediatricians at 12 sites recorded anonymous data on structured forms for ≤15 consecutive referrals.

Objective: To determine whether access to an Autism Patient Navigator (APN) for children diagnosed with autism spectrum disorder (ASD) at <48 months of age would be useful and lead to more appointments with needed services.

Method: Participants included parents of 39 children diagnosed with ASD in a multidisciplinary clinic. After diagnosis, the patients were randomized to 4 groups: Medicaid early (n = 9) or late support (n = 9) and non-Medicaid early (n = 11) or late support (n = 10).

Objective: To determine the prevalence of hearing loss in newborns with Down syndrome.

Study Design: We performed a cross-sectional, retrospective chart review of all infants with Down syndrome born at a university-affiliated hospital (n = 77) or transferred in to the associated pediatric hospital (n = 32) following birth at an outlying hospital between 1995 and 2010. We determined the rate of failure of newborn hearing screens, the proportion of infants lost to follow-up, and the rate of confirmed hearing loss, as well as the associations of risk factors for hearing loss with confirmed hearing loss.

Objective: To determine the frequency of medical problems in a large population of children with Down syndrome.

Study Design: Study population included 440 children with Down syndrome (ages 3-14 years) identified primarily through the New York Congenital Malformations Registry. Parents completed questionnaires on medical problems.

Context: Twelve to twenty-one percent of children and adolescents have psychiatric disorders with at least mild functional impairment. Pediatricians and family medicine physicians prescribe 85% of psychotropic medications taken by children. However, little is known about the comfort level of these physicians with the diagnosis and treatment of psychiatric disorders in children.

Background: The majority of children with 22q11.2DS deletion syndrome (22q11.2DS) have learning disabilities, and a substantial number have mental retardation.

Objective: To examine prevalence rates of psychopathology in children with velocardiofacial syndrome (VCFS).

Method: One hundred fifty-four children ages 6 to 15 participated in our between-group design with three samples, 84 children with VCFS (37 girls, 47 boys), 32 sibling controls (18 girls, 14 boys), and 38 community controls (12 girls, 26 boys). The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version and several other parent report measures were used to assess for psychopathology.

In their role as committed advocates, parents of children with Down syndrome have always sought alternative therapies, mainly to enhance cognitive function but also to improve their appearance. Nutritional supplements have been the most frequent type of complementary and alternative therapy used. Cell therapy, plastic surgery, hormonal therapy, and a host of other therapies such as massage therapy have been used.

Background: The American Academy of Pediatrics (AAP) has published clinical practice guidelines for the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD). However, implementation of guidelines has been notoriously difficult to achieve in the wider context of changing individual physicians' clinical practice.

Objective: Implement a formalized diagnostic protocol for ADHD and study whether this protocol improved adherence of pediatric residents and faculty to published guidelines for the diagnosis of ADHD.

A survey of developmental-behavioral pediatricians was conducted to obtain data and insights on their current practice. As part of the Future of Pediatric Education (FOPE) II Survey of Sections Project, questionnaires were sent to individuals who were most likely to represent those pediatricians engaged in the subspecialty of developmental-behavioral pediatrics. Four groups of physicians were compared within the survey: developmental-behavioral fellowship group (n = 272), developmental disabilities fellowship group (n = 139), general academic pediatrics or other fellowship group (n = 57), and a nonfellowship group (n = 224).

Nongenetic causes of hearing loss.

Ment Retard Dev Disabil Res Rev

September 2003

Nongenetic as well as genetic etiologies must be explored in the child with identified hearing loss. Graduates of the neonatal intensive care unit are at increased risk for developing hearing loss due to hypoxia, hyperbilirubinemia, very low birth weight, and ototoxic medications. Although meningitis has decreased in frequency, it is still a risk factor for hearing loss.

The sequencing of chromosome 21 and the use of models of Down's syndrome in mice have allowed us to relate genes and sets of genes to the neuropathogenesis of this syndrome, and to better understand its phenotype. Research in prenatal screening and diagnosis aims to find methods to identify fetuses with Down's syndrome, and reduce or eliminate the need for amniocentesis. Other areas of active research and clinical interest include the association of Down's syndrome with coeliac disease and Alzheimer's disease, and improved median age of death.

As the child with Down syndrome enters the second decade of life, some of the original medical issues, such as cardiac, vision, and hearing problems, continue to concern parents. Dermatologic and podiatric problems may become particularly bothersome. Although the child may be doing well, monitoring for thyroid and celiac disease continues to be needed.
