3The History of Diabetes
- Diabetes was first diagnosed by Greek physician
Aretaeus of Cappodocia in the 1st Century A.D. - He deemed it a wonderful affection . . . Being
meltdown of the flesh and limbs into urine. For
the afflicted, life is disgusting and painful
thirst unquenchable . . . And one cannot stop
them from drinking or making water.
4The History of Diabetes
- Aretaeus referred to the disease state as
Diabetes. It is from the Greek word meaning to
siphon or passing through. - In 1675, Thomas Willis added mellitus to the word
diabetes. Mellitus stems from the Latin word
meaning honey.
5The History of Diabetes
- 1870s French physician notices the
disappearance of glycosuria in his patients with
diabetes during rationing of food in Paris while
under siege by Germany during the Franco-Prussian
war formulates idea of individualized diets for
his patients with diabetes.
6The History of Diabetes
- Oskar Minkowski and Joseph von Mering remove the
pancreas from a dog to determine the effect of an
absent pancreas on digestion in 1889. - 1900-1915 Fad diabetes diets included
- Oat cure
- Milk diet
- Rice cure
- Potato therapy
- Opium
7The History of Diabetes
- Fredrick Allen publishes Studies Concerning
Glycosuria and Diabetes and Total Dietary
Regulation in the Treatment of Diabetes.
Recommended drastically restricting caloric
intake. - Establishes the Physiatric Institute in New
Jersey in 1919 and treated patients with diabetes
and hypertension there.
8Patient prior to Insulin Therapy
13 year old female weighing 45 lbs.
9Development of Insulin
- 1920 Fredrick Banting removes the pancreas
from dogs. - Summer 1921 Insulin used to successfully treat
a dog whose pancreas was removed. - Banting presents The Beneficial Influences of
Certain Pancreatic Extracts on Pancreatic
Diabetes in December 1921.
10Dr. Banting and Dr. Best
With Marjory (one of the experimental dogs).
11What about the patient?
12Bad Old Days of Diabetes
(Before 1980)
- 1 or 2 insulin injections a day
- Urine tests for glucose
- Aggressive therapy unsafe and of unknown benefits
- Hemoglobin A1Cgt10
- Eye and kidney complications
13Early 1980s
- Intensive insulin therapy was made
- possible by the introduction of
- Self Monitoring of Blood Glucose
- Hemoglobin A1c assays
- Multiple daily injections (MDI) and Continuous
Subcutaneous Insulin Infusions (CSII)
14Type 1 Diabetes Mellitus
- Previously referred to as insulin-dependent or
juvenile diabetes - Polygenic, multifactorial, autoimmune disease
- Most commonly occurs in the young
15Epidemiology
- In 2004, 3 million Americans were estimated to
have type 1 diabetes. - There is a 3 increase in incidence per year.
- Approximately 1 in every 400-500 children has
type 1 Diabetes. - Diabetes is second most common chronic disease in
childhood after asthma.
16Epidemiology
- Peak ages at onset 5-7 and early puberty
- 30 of cases onset 18 - 40 years of age
- There is a genetic association in regards to the
risk of developing diabetes.
17Risk for Type 1 DiabetesBy Family Member with
Diabetes
18Pathogenesis of T1DM
- T-cell mediated process directed at pancreatic ?
cell. - Pancreatic islet cell destruction results in
absence of insulin. - Absence of insulin causes chronic hyperglycemia.

20What does insulin do?
- Insulin is a hormone secreted by the ?-cells of
the pancreas in response to rising glucose
levels. - Insulin is a key that allows peripheral tissues
to open and allow glucose to enter.
21What does insulin do?
22Absence of Insulin
- Absence of insulin causes the body to act in
fasting state, despite being fed. - Serum glucose cannot be used by peripheral
tissues because of dependence on insulin. - Stimulation of hepatic glycogenolysis and
gluconeogenesis cause further hyperglycemia. - All of the above cause serum glucose levels to
exceed the renal threshold (180 mg/dl) and
glucose is spilled into the urine.
23Osmotic Diuresis
- Once the renal threshold of 180mg/dL is exceeded
glucose is spilled into the urine. Water is
dragged out along with the glucose due to the
molecular weight of glucose in a process known as
osmotic diuresis. - Polyuria persists and the body struggles to
maintain homeostasis by taking in more fluid. - Without glucose cells resort to lipolysis and
proteolysis (breakdown of fatty acids and amino
acids for energy) leading to an accumulation of
ketone bodies. - Weight loss results.
24New Onset Patients
- Symptoms
- Polydipsia
- Polyuria
- Weight loss
- Vomiting
- Nocturia
- Abdominal Pain
- Decreased energy
- Fatigue, General Malaise
25New Onset Patients
- Started on subcutaneous insulin.
- Instructed on basics of diabetes care including
- How to check blood glucose
- Basic nutrition guidance
- How to administer insulin injection
- Basic understanding of different types of insulin
- Treatment of low bloods sugars
- What to do in case of high blood sugars
26Treatment Goals
- Monitoring of blood glucose levels at least four
times a day - Nutrition sufficient for growth
- Insulin to achieve near normal blood glucose
levels - Activity and exercise
- Quarterly HbA1c levels
- Support child and family psychologically
- Prevent complications
27Blood Glucose Monitoring
- Meters require a small amount of blood
(0.3microliters for freesytle flash) - Most meters allow for alternate site testing
(forearm or finger) - When to test
- At least 4 times a day (before meals and before
bed) - As needed for symptoms of low and high blood
sugars - Before and after exercise
- Prior to driving
28Meal Planning for Type 1 DM
- All carbs (except fiber) are absorbed in the form
of glucose molecules - The total amount of carbs eaten has a greater
effect on blood glucose rise than does the type
or the source of carb. - Keep carb intake consistent during meals from day
to day if on fixed doses or adjust insulin dose
to food intake (bolus).
29Carbohydrate Counting
- Allows for more flexibility
- Only grams of carbohydrate are counted
- Insulin dose is varied based on amount of carb
and blood sugar level - However, it is important to note serving size!
30What About Sugar?
- Carbohydrates are carbohydrates no matter what
the source of the carb is. - Table sugar, sweets, and candy will be broken
down into glucose. - As long as someone with diabetes counts the
carbohydrate they are eating or follows a
pre-specified amount of carbohydrates daily, it
is okay to eat such foods.
31Free foods No need to bolus
- Non-starchy vegetables
- Low-fat cheese and lean meats
- Pickles, eggs
- Unsalted nuts and seeds, peanut butter
- Artificially sweetened drinks with Nutrasweet or
Splenda - Sugar-free jello, popsicles and syrup
32Meal Planning for T1DM
- Remember to Treat Children with Diabetes
- like all other Children
- Adjust insulin regimen and doses to
- their lifestyle and eating habits
-
- Flexibility is important!

- Controversy remains about the level of glycemic
control that should be targeted for children
despite the findings of fewer complications with
better control. - Concerns exists given the high risk of
hypoglycemia and what hypoglycemia can do to the
developing brain.

45How can insulin be delivered?
- Draw up from vial and administer with syringe
- Insulin pens
- Insulin pumps
46Insulin via Syringe
- Insulin is drawn from a vial into a 28-31 gauge
insulin syringe - Used for all patients who are newly diagnosed
with diabetes as insulin doses are being adjusted
daily
47Insulin Pens
- Doses are dialed up
- Administer like insulin injection via syringe and
hold down back of pen - Benefits Faster than syringe injections
- Drawbacks Less fine tuning of doses due to
increments and pre-mixed pens come in specified
dosages (70/30 or 75/25)
48 The Development of the Insulin Pump
- Initially, subcutaneous infusion pump being used
by Howard Pearson for patients with thalessemia
major. - Decision made to try insulin delivery with pump
to children with type 1 diabetes.

51The Development of the Insulin Pump
Autosyringe AS2C Used 50mL syringe Had only one
basal rate No memory Slightly noticeable when
worn
52Advances to Pumps
- Smaller size (roughly the size of a pager)
- Multiple basal rates
- Temporary basal rates
- Direct glucose entry from meter or continuous
monitor - Able to check history
- Reminders and alerts
- Ability to disconnect infusion sets
- Bolus wizard availability
- Preprogrammed carbohydrate ratios and correction
factors - Glucose targets
- Duration of insulin action
53New Insulins for Use in Pumps

54Insulin pumps versus multiple daily injections
(MDI)
- Advantages of pumps
- More reliable insulin action
- Greater precision in dosages
- Automatic dose calculation with smart pumps
- Flexible mealtimes
- Flexible schedule (exercise, shift work, skipping
meals) - Increased sense of well being
55Pump Basics
- Target Blood Glucose glucose to which your pump
will correct your blood glucose using correction
factor. May have multiple target blood glucose
based on time of day. - Daytime target blood glucose 100mg/dL
- Overnight target blood glucose 120mg/dL
56Pump Basics
- Bolus a quick release or burst of insulin
- Carbohydrate Ratio - the ratio of how many grams
of carbohydrates are covered by each unit of
insulin - Example 1 unit for 10 grams of carbs
- Correction Factor - the mg/dL that each unit of
insulin will drop your blood glucose. - Example 1 unit for 50mg/dL
57Pump Basics

69Infusion Sets
- Tubing may be disconnected without removing
insertion site - Should be removed for swimming or bathing
- Should be removed for contact sports
- May be removed for other sports
- If disconnecting for more than 2 hours, patients
should check their blood sugars, reconnect, and
give a bolus to prevent hyperglycemia
70Bad Infusion Sets
- Infusion set may go bad (pulled out, kinked, or
blocked). - Because the pump only uses rapid-acting insulin
if the site is not changed may end up with
hyperglycemia or Diabetic Ketoacidosis. -
- So, if someone on a pump has a high blood sugar
- 1- A correction is given through the pump.
- 2- Re-test blood sugar in 2 hours. If still
high, then change infusion set and give injection
of insulin. - 3- Check urine for ketones.
71How are the pumps worn?
- Older patients will wear the pump on a clip which
can be attached to a belt, pants, or in a pocket. - Pumps can also be left without a clip inside a
pocket. - Special pump holders are sold which can be
attached to the thigh or inside of bra to hold
pump for discretion. - Younger patients may use pump packs.
72(No Transcript)
73Continuous Glucose Monitoring
- Subcutaneous catheter placed.
- Measures glucose in interstitial fluid.
Conversion done to display blood glucose in
mg/dL. - Glucose measured every 5 minutes.
- Must be calibrated with fingerstick blood glucose.
74Continuous Glucose Monitoring
- Increased sense of security.
- Trend arrows for real time adjustment.

77The highs and lows of diabetesHypo and
Hyperglycemia
78Causes of Hypoglycemia
- Too much insulin
- Inadequate food intake
- Delayed meals or snacks
- Exercise
79Symptoms of Hypoglycemia
80Moderate/Severe Hypoglycemia
- Lethargy
- Extreme weakness
- Unsteady Gait
- Combativeness
- Seizure Activity
- Unresponsiveness
81Treatment of Mild Hypoglycemia
- Child is responsive and able to swallow
- Blood sugar is lt70mg/dL
-
- Give 15 grams of FAST ACTING carbohydrate
- (3-4 ounces of juice, 3 glucose tablets)
- Re-test in 15 minutes if persistence of symptoms
see if blood sugar has risen.
82Treatment of Mild Hypoglycemia
- Children who are able, can keep this treatment in
the classroom. - Children should be assisted to the nurses office
if necessary. - Children on insulin pumps may need less glucose
for treatment.
83Over treatment of Hypoglycemia
- More is not always better!!!
- Over treatment of lows can cause hyperglycemia in
the next 1-3 hours - If patterns of lows persist over days, family
should be notified so insulin adjustments can be
made.
84Treatment of Moderate/ Severe Hypoglycemia
- Defined as requiring assistance of an adult to
get treatment. - If child is able to sit and swallow, use juice or
glucose tablets - If unable to swallow, use glucose gel first
squirting the tube on the buccal mucosa. - If gel isnt bringing the glucose up, then use
call 911 and/or use glucagon.
85Glucagon
- If altered level of consciousness or seizure
activity consider glucagon use. -
- Mix powdered glucagon with diluent.
- Draw mixture up in insulin syringe.
- Administer subcutaneously.
86Prevention of Hypoglycemia
- Child may need juice or glucose tabs before gym
class or recess - If necessary, the pump may be disconnected for
gym class or recess. - If recurrent lows inform the parents so they can
call their clinicians to make dose adjustments.
87Hyperglycemia
- In children and teens dx with T1D, glucose levels
over 130/140 mg/dl are considered high. - Hemoglobin A1c target range is 6-7 for children
and teens. - The child may not have symptoms of a high until
glucose level is over 250.
88Causes of Hyperglycemia
- Inadequate doses of insulin
- Additional carbohydrates
- Missed injection of insulin glucose will be
very high with ketones - Malfunctioning pump catheter glucose will not
respond to corrections given via pump, ketones
may be present - Illness ketones may be present
- Lipohypertrophy scar tissue at injection site
89Symptoms of Hyperglycemia
90Hyperglycemia Correction
- Correction can take 2-3 hours to normalize
glucose - If glucose is not decreasing after 2 hours in a
child on pump, then insulin injection should be
given - If the child feels okay he/she may
- Return to class
- Participate in gym
- Sugar free liquids help with hydration
- Contact Yale if treatment plan requires
clarification
91Hyperglycemia Correction
- Most patients will have personalized correction
factors but the guidelines below can be helpful
to determine a correction factor based on age.
92Signs/Symptoms of Hyperglycemia and Ketonuria
- Extreme thirst
- Increased urination
- Abdominal pain
- Nausea/vomiting
- Weakness
- Dizziness
- Labored breathing
93Treatment of Hyperglycemia with Ketonuria.
- Parents should be contacted immediately
- Parents call Yale Pediatric Diabetes Clinic
- Increased amounts of insulin will be required via
injection. - Provide sugar free liquids.
- Insulin is required even with vomiting and
hypoglycemia with ketones. - No exercise with ketones
94 95Scenario 1
- A student on a pump performs a routinely
scheduled BG test just before lunch and the
result is 61 mg/dL. The student is asymptomatic.
- What is the most appropriate action to take?
96Scenario 2
- 13 yo student on a pump. Pre-lunch blood
glucose is 302 mg/dL. The student boluses for
both meal coverage and a correction. You ask the
student to come back 2 hours later for a BG
check. At that time, the BG is 290 mg/dL. - What is going on?
97Scenario 3
- A 6yo student is normally quiet and follows
directions well. One afternoon during quiet
reading time he starts to read out loud and
states he is tired and puts his head down on the
desk. - What is most likely going on?
98Scenario 4
- 16yo patient on injection therapy comes to your
office mid-morning saying that they are not
feeling well. Upon questioning, you find out
that the patient left the house that morning
without testing the BG or taking any insulin - What do you do now?
99Scenario 5
- A 9yo student has had BG levels gt 250mg/dl for
at least 3-4 days per week for the last 2-3
weeks. You have been calling the parent who has
asked that you give the prn order for insulin. - What is the best course of action for managing
this patients BG levels?
100Scenario 6
- A 12yo student come into your office shortly
after arriving at school and states she is not
feeling well. She indicates that she did not eat
much this morning because her stomach hurts and
everyone at home has the stomach bug. She
proceeds to vomit in the office - What is/are the first steps to take?
101Scenario 7
- One of the 6th grade teachers calls you at the
beginning of the school day to let you know that
a mother is bringing in cupcakes for the class.
They will be having the cupcakes whenever the
mother arrives. The teacher is concerned about
the 11yo boy who was recently diagnosed w/
diabetes. She called to ask your opinion about
what to do. - What is the best course of action?
102 103Meal Planning
- Sugar is NOT a bad word
- Children with diabetes should not be excluded
from school parties or events - On the Pump, parties or special events may
require additional bolusing - With injection therapy, parties or special events
should be planned for ahead of time
104A Parents Role
- Work with the school and healthcare team to
design a diabetes management plan that normalizes
the childs life as much as possible - Supply all materials needed for BG monitoring
- Supply preferred treatments for Low blood sugars
- Supply individualized information related to
diabetes in their child (including meal planning) - Supply emergency contact numbers
105A Schools Role
- Train adults who will interact with the child
about diabetes - Identify at least 2 adults who can perform
diabetes management tasks - Allow for immediate access (in the classroom) to
hypoglycemia treatments - Communicate with parent as needed to modify
diabetes plan - Permission for the child to eat a snack when
necessary wherever they may be - Access to water and bathroom as needed
- Diabetes supplies should go with the child during
extracurricular activities or field-trips
106The Take Home Message
- Diabetes is a complex condition.
- Children with diabetes are not sick
- Children with diabetes should be allowed to
participate fully in all school-sponsored
activities - Successful diabetes management requires a team
approach involving the child, parents, school
personnel and healthcare providers
107 Our Philosophy
- One of the biggest things to always remember is
our patients arent diabetic they have diabetes.
We will educate them not to define themselves by
their diabetes, but to live with this disease. - Diabetic Has diabetes
108Thank you!
