2. Metabolic Disorder of Hyperglycemia & Ketosis
Results From Deficiency of Insulin Production in The Pancreas
Most Common Age of Presentation is 5-7Y Then Also in Adolescence
Rate in The Developing World Like Most Autoimmune Disease, is on The Rise
Pathology
Signs & Symptomes
A. Early Presentation
Weight Loss
Fatigue
Poly (Uria, Dipsia, Phagia)
B. Late Presentation
Polyuria Despite Dehydration
Delayed Capillary Refill, Dry Mucous Membranes
Sweet or Musty Breath Odor (From Ketones)
Tachycardia, Tachypnea
Confusion / Coma
VT/VF (Secondary to Hyperkalemia)
3. Dx
RBS (Random Glucose) > 200 mg/dl + Signs or Symptoms Of IDDM 1
Fasting Glucose Levels > 126 mg/dl (8h Fast) or 2H Post-Glucose Challenge > 200 mg/dl
HbA1C > 6.5 %
DIABETIC KETOACIDOSIS
Dx:
Hx. & Clinical Examination
Acidosis
1. PH < 7.35 , HCO3 < 15 mEq/dl
2. Pseudohypo-Na & Pseudohyper-K
Hyperglycemia (Glucose>300 mg/dl)
Ketonuria or Ketonemia (+ve)
Low C-Peptide
Management:
2 IV Lines
1st Line For Rehydration
2nd Line For Insulin
Finally Correct Electrolytes Disturbances
Admission to ICU

4. Representative Profiles of Insulin:
Traditional Methods for Insulin Delivery (S.C Route ) Daily Requirements:
0.7 unit/kg (Pre-Adolescents)
1 (Adolescents)
1,2 (Post-Adolescents)
Regimen 1:
2/3 At Morning (Mixtard 70% LA, 30% SA)
1/3 At Night (Mixtard 70% LA, 30% SA)
Regimen 2:
1/2 At Night (LA Glargine)
1/2 Divided For 3 Dose With Each Meal (VSA Aspart & Lispro)
5. 1. Tell Them About Hypoglycemia:
Signs & Symptoms (Tremors, Sweating, Palpitations, DLOC, Seizures)
Management (Directly Give Something Sweet or Use I.M. Glucagon Injection)
2. Ask The Father to Inform The Teachers About His Child Condition Especially The
Hypoglycemia & How Treat it Early
3. Also The child with DM should
Avoid Food With High Sugar (Pepsi, chocolateetc)
Eat More Than 3 Meals At Day
The Diet Should Continue 50-65% CHO, 25-30% Proteins & The Reminder is Fat
4. Allowed to Do Simple Exercises But Not Heavy Exercise
5- Follow up for :
Complications (Autoimmune Diseases Vitiligo & Coeliac Disease)
Growth & Height
Complications of DM
Acute (DKA, Hypoglycemia)
Chronic (Retinopathy, Neuropathy & Nephropathy)
Counselling:
6. A 7-year-old girl, 30 kg body weight presented to the ER with a 2-week history of being generally
unwell. Over the previous 2 days she had been vomiting and that evening she had started to become
delirious. On further discussion with the mother, it was found that the girl had been drinking
excessively, and unusually she had also been going to the toilet during the night. It was also thought
that she had lost some weight.
On examination, She was breathing spontaneously but shallowly and at a relatively rapid rate.
Auscultation of the chest revealed bilateral air entry. She was noted to be dehydrated with sunken
eyes. Her Glasgow Coma Score (GCS) was assessed as 8/15 (E2, M4, V2) as she was only responsive
to pain.
1. Past medical history

2. Regular medications
None
3. Allergies

4. Examination
Awake and responsive, but slightly confused Airway clear, face mask oxygen, breath ketotic Chest
clear, bilateral air entry, Sats 98% in air
Respiratory rate 35 min-l
