Slide 1-

Pancreas & diabetes Željka Kušter Mentor: A. Žmegač Horvat
Slide 2-

Anatomy Retroperitoneal abdominal organ Exocrine and endocrine cells lobules ducts pancreatic duct
Slide 3-

ppt slide no 3 content not found
Slide 4-

Exocrine function Acinar cells - exocrine cells of the pancreas that produce and transport digestive enzymes Amylase, lipase, phospholipase, proteases (trypsinogen, chymotrypsinogen)
Slide 5-

Endocrine function Islets of Langerhans - endocrine cells of the pancreas that produce and secrete hormones into the bloodstream Glucagon - Alpha cells (A cells) - raises the level of glucose (sugar) in the blood Insulin - Beta cells (B cells) - stimulates cells to use glucose Somatostatin - Delta cells (D cells) - regulate the secretion of glucagons and insulin
Slide 6-

Pancreatitis Inflammation of the pancreas
Slide 7-

Acute pancreatitis Pancreas suddenly becomes inflamed Causes: Gallstones Ethanol Trauma Steroids Mumps Autoimmune Scorpion venom Hyperlipidaemia, hypothermia ↑Ca2+ ERCP Drugs
Slide 8-

Symptoms epigastric and central abdominal pain vomiting and nausea swollen and tender abdomen fever dehydration and low blood pressure Diagnosis medical history and physical exam blood test: ↑ amylase, lipase abdominal ultrasound, EUS, CT scan
Slide 9-

Treatment nothing to eat or drink intravenous fluids analgesia ERCP and gallstone removal Complications shock, ARDS, renal failure, DIC, sepsis, ↓Ca2+ pancreatic necrosis, pseudocyst, abscesses, bleeding, thrombosis
Slide 10-

Chronic pancreatitis inflammation of the pancreas - gets worse over time and leads to permanent damage Causes: many years of alcohol use hereditary disorders of the pancreas cystic fibrosis haemochromatosis autoimmune conditions
Slide 11-

Symptoms nausea and vomiting weight loss diarrhea steatorrhea Diagnosis medical history and physical exam abdominal ultrasound, CT scan, MRCP, ERCP
Slide 12-

Treatment drugs - analgesia, lipase, fat-soluble vitamins diet surgery – pancreatectomy pancreaticojejunostomy Complications pseudocyst, diabetes, biliary obstruction, local arterial aneurysm, splenic vein thrombosis

Slide 14-

Diabetes increased level of glucose in the blood (normal blood glucose level 3.5-6.0 mmol/l) Type 1 ( insulin-dependent DM, IDDM) destruction of insulin-secreting pancreatic β cells juvenile diabetes patient always needs insulin
Slide 15-

Type 2 (non-insulin dependent DM, NIDDM) insulin resistance Β cell dysfunction, ↓insulin secretion Causes of insulin resistance: metabolic syndrome (central obesity, hyperglycaemia, hypertension, ↓HDL cholesterol, ↑triglycerides) renal failure pregnancy cystic fibrosis polycystic ovarian syndrome
Slide 16-

Mechanisms of insulin resistance: post-receptor defects in insulin action gene mutation circulating autoantibodies
Slide 17-

Slide 18-

Diagnosis blood glucose level urine sample HbA1c test
Slide 19-

Treatment: diet oral hypoglycaemics
Slide 20-

insulin injections (long-acting, short-acting, rapid-acting) insulin pen insulin pump therapy
Slide 21-

Complications
Slide 22-

diabetec ketoacidosis hypoglycaemia diabetic retinopathy
Slide 23-

atherosclerosis (heart disease and stroke) neuropathy (diabetic foot care)
Slide 24-

Diabetes risk factors Age over 45 years Diabetes during a previous pregnancy Excess body weight Family history of diabetes Dyslipidaemia Hypertension Low activity level Metabolic syndrome Polycystic ovarian syndrome Acanthosis nigricans
