  4. Diabetes Mellitus: a group of diseases characterised by high levels of blood glucose resulting from defects in insulin production, insulin action, or both • Consists 2 main types: 1) Type 1 diabetes 2) Type 2 diabetes

  5. Diabetes Mellitus: a group of diseases characterised by high levels of blood glucose resulting from defects in insulin production, insulin action, or both • Consists 2 main types: 1) Type 1 insulin secreting cells destroyed 2) Type 2 diabetes

  6. Diabetes Mellitus: a group of diseases characterised by high levels of blood glucose resulting from defects in insulin production, insulin action, or both • Consists 2 main types: 1) Type 1 insulin secreting cells destroyed 2) Type 2 insufficient insulin action

  7. Why to treat diabetes mellitus? stroke blindness myocardial infraction kidney failure haemodialysis gangrene amputation nerve damage • In type I acute complication and death

  8. How to treat diabetes? • Insulin is applied subcutaneously • Before application glucose level is measured • Glucose regulation is one of the most sophisticated ones in the body • Impossible to imitate

  9. INFORMATION • What is happening with me today? • How high is the glucose level now? • Am I going to eat a lot? • Is my food going to contain many carbohydrates? • Am I going to perform an exercise and for how long? • How much insulin should I apply? • Which type of insulin should be applied and when? • When is the proper time to measure blood glucose again?

Educational tutorials • web sites designed for educational and teaching purposes • AIDA: a freeware diabetes software simulator / modelling program of blood glucose-insulin action + insulin dose & diet adjustment • for education, self-learning & teaching diabetes programmes www.2aida.net/welcome

  23. Glucose monitoring • Continuous glucose monitoring • tiny sensor inserted under the skin checks glucose levels • sensor stays in for several days • transmitter sends information about glucose levels via radio waves to wireless monitor • pricking a fingertip • using a glucose meter that measures the blood sample’s glucose level

  24. Glucose monitoring • Software systems download data to a computer to see patterns and trends in their glucose levels • Send to a physician by email • Analyse, store

  25. Insulin pump • disposable infusion set: • short tube with a needle • tubing system the pump itself: • controls • processing module • batteries reservoir for insulin • delivers insulin continuously into the body

  26. Artificial pancreas • Science fiction?

  29. closed loop system data from continuous glucose monitoring blood glucose reading every few minutes sensor is connected via wire to the insulin pump blood glucose variation is signalling to the pump how much insulin to deliver Artificial pancreas =insulin pump + continuous glucose monitoring Friedrich M J.

  30. Telemedicine • medicine at distance • facilitates communication among two or more medical professionals or among medical professional and patientcare • Telemedicine on Croatian islands • Croatian Telemedicine Society of the Croatian Medical Association

  31. Telemedicine Croatia-Japan • Live TV report ( National Japanese TV) about successful telemedicine activities in cardiology between National Institute of Health, Osaka, Japan and Makarska, Croatia www.mef.hr/telmed-MA2002

  32. In 1922 a 14-year-old boy Leonard Thompson, patient with diabetes type 1, was dying from ketoacidosis. He was the first patient who got insulin in therapy. Without insulin he would dye in a few days, but the fact that he lived 13 years more was considered a miracle

  33. “We have data on hand today that suggests that you could get much better diabetes outcomes with the computer taking the lead instead of the person with diabetes doing it all themselves.” Aaron Kowalski research director of the Juvenile Diabetes Research Foundation's Artificial Pancreas Project
