    Overview Stony Brook Children's is home to a strong Pediatric Endocrinology Division with a wide range of expertise in diagnosing and treating endocrine disorders. A clinical resource for all of Suffolk County, we also are a designated endocrinology referral site for the State of New York's Newborn Screening Program. The Division treats newborns to young adults in both the inpatient and outpatient setting. Our child- and family-focused care is multidisciplinary, enhanced by the invigorating dialogue and advanced practices characteristic of an academic medical center. Working within the context of a teaching hospital and medical school, we also train tomorrow's specialists and engage in a variety of significant research.

    Our Team The core of our team consists of four board certified endocrinologists. A full-time, certified diabetes educator/pediatric nurse practitioner and a pediatric nutritionist play key roles. Our patients also have access to social services professionals. Three fellows in pediatric endocrinology enhance the division's capacity.

    Patient Resources Child- and family-centered, multidisciplinary care is standard in the division of pediatric endocrinology. Because many of the illnesses we treat are affected by compliance in medication, diet, and lifestyle choices, we devote a full-time nurse practitioner to education as well as clinical support, and we have a dedicated nutritionist providing information and diet plans for healthy eating. Together, we work as a team to help patients and families understand and fulfill their role staying healthier.

    Research and Education The pediatric endocrinology division is interested in the effect of insulin on protein metabolism; the effect of insulin on body composition; and the relationship between diabetic control and memory. We are researching ways to preserve beta cell function (the cells that make insulin) in new onset diabetes, and exploring the potential role of IGF-1 in the treatment of cystic fibrosis. A study of autoimmune thyroid disease and celiac disease in children has just been completed.

    Advances and Recognitions


    Pediatric Endocrinology Fellowship Training Program. The pediatric endocrinology division hosts a fellowship program that was recently re-accredited by the Accreditation Council for Graduate Medical Education (ACGME). This program trains pediatricians in endocrinology.


    New York State Newborn Screening Referral Site. Stony Brook a designated referral center for the New York State Newborn Screening Program, which screens every newborn shortly after birth with a tiny blood sample taken from the heel. Long Island newborns with thyroid or adrenal disorders are referred to us to confirm the diagnosis and provide treatment.


    Less Scary Blood Tests. The pediatric endocrinology division is always looking for ways to make medical care more comfortable for kids. Previously, standard procedure for children with diabetes was to go to a commercial laboratory for a blood draw every few months to monitor their diabetic control. However, for many children, blood draws can be scary. Recently, we reduced the anxiety around testing for diabetes control by switching to a simpler procedure: in-office finger stick hemoglobin A1c tests. Our staff can use a lancet to prick the patient's finger for a tiny drop of blood rather than requiring venipuncture in a lab.

    Definitions Adrenal glands - Located above each kidney, these glands make cortisol, androgens and aldosterone, hormones that regulate sodium (salt) balance, blood sugar, blood pressure and play a role in sexual development during puberty.


    Calcium, phosphorus and bone disorders - Hypocalcemia (low serum calcium concentration) and hypercalcemia (high serum calcium concentration) as well as disorders resulting in defective mineralization of bone in children, including various types of rickets.


    Diabetes - One of the world's most common chronic conditions, diabetes mellitus is a group of metabolic diseases that occur when the body fails to regulate the serum concentration of glucose (sugar) correctly.


    Endocrinologist - A physician that specializes in the function of the endocrine system and treatment of its disorders.


    Gender identity disorders - Conditions in which children and adolescents feel they belong in a different gender.


    Hypoglycemia - Lower than normal blood sugar levels.


    Lipid disorders - Abnormal levels of triglycerides or cholesterol in the blood.


    Metabolic syndrome - A combination of risk factors that increase the risk for heart disease and diabetes.


    Sexual differentiation disorders - Includes children with abnormal genital development or sexual differentiation.


    Thyroid disorders - Disorders when the thyroid gland is overactive or underactive or when the thyroid gland is enlarged (goiter), including thyroid nodules.
