DIABETES IN CHILDREN AND ADOLESCENTS: ANYTHING NEW AND EXCITING?
FYI: Below, I have posted a short outline and reference list to accompany a lecture I was asked to give at the University of Missouri Annual Family Medicine Update, April 2013. If you want a copy of the actual powerpoint from the lecture, let me know and I will send it to you. By the way, the answer to the question posed in the lecture title is that not much is new, at least over the past 20 years or so. But, we did make extraordinary advances in diabetes care back in the 1990s which have not yet been fully translated into better patient care. I am not exaggerating when I state that all diabetes chronic complications are now more or less completely preventable; yet many patients are still developing serious complications of the disease. We as physicians, nurses, dietitians, and others who care for patients with diabetes must do whatever it takes to lead to better patient outcomes. Of course, it is not enough that health care givers do their part; patients and their families also must do their part.
DIABETES IN CHILDREN AND ADOLESCENTS: ANYTHING NEW AND EXCITING?

35Th Annual Family Medicine Update- April 19-20, 2013
1. Diabetes mellitus is a syndrome with many different causes, all of which have three things in common: insulin deficiency, hyperglycemia, and risks for the development of chronic complications. About 95% of patients have either type 1 (T1DM) or type 2 (T2DM) diabetes.
2. Most diabetes in children and adolescents is T1DM, an inherited, autoimmune disorder with destruction of the pancreatic islet beta-cells. About 1 in 500 children and adolescents in the U.S. have T1DM; about 1 in 1000 have T2DM but it is rare before age 10 yrs. The prevalence of T2DM is 3-5 times higher in African American and Hispanic American youth than in non-Hispanic white youth.
3. Most patients with T1DM present in the “classic” manner with polyuria, polydipsia, and poly/hyperphagia with weight loss over the previous 2-4 weeks. About 40% of patients have ketoacidosis (DKA)at presentation. DKA should be always considered a medical emergency. Very young children often present with a flu-like illness. Some patients present with an “acute abdomen,” which can be mistaken for acute appendicitis.
4. Diagnosis can be established by one of the following criteria: random plasma glucose > 200 mg/dl with typical symptoms; fasting plasma glucose 126 mg/dl or greater; plasma glucose 200 mg/dl or greater 2 hours after a 75 gm oral glucose load; or hemoglobin A1c (HbA1c) 6.5% or greater.
5. Routine management is best accomplished by a “team approach,” that ideally includes a diabetes specialist, dietitian, nurse-educator, a social worker, and a behaviorist. The patient’s primary care physician/nurse should be part of the team. Treatment goals should be defined at the onset and reviewed frequently. Key care components include the following: appropriate insulin therapy (basal-bolus), monitoring of glycemic status (daily fingerstick blood glucose testing by patients and HbA1c testing) , nutrition counseling, and monitoring for chronic diabetes complications. Patient and family education at the onset and at regular intervals are critical to success.
6. In the long run, an important goal is for patients to be independent in managing all aspects of their diabetes. But, shared responsibilities between pediatric patients and their parents are critical to success. The health care team must fully understand developmental stages and not promote too much or too little patient independence in the diabetes management.
7. The future is bright for children with diabetes. Better insulin delivery systems and better methods for monitoring glycemic control and for preventing hypoglycemia are on the horizon. Both prevention and cures for diabetes remain important but elusive goals to achieve.
