What is the Peritoneum/what does it do?
A membrane that forms the lining of the abdominal cavity and covers most of the intra-abdominal organs
What are the greater and lesser omentum?
Omenta are fused peritoneal folds that connect the stomach and duodenum with other abdominal organs
Can you list the Retriperitoneal organs?
Hint: SADPUCKER
S = Supra (adrenal) glands A = Aorta/IVC D = Duodenum P = Pancreas U = Ureters C = Colon K = Kidneys E = Oesophagus R = Rectum
What does Vitamin A help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with Vision - forms light absorbing pigment rhodopsin
Maintains healthy skin and body immunity
Deficiency = Night blindness, dry mucous membrane, Infection
Excess = Fat soluble vitamins retained over time resulting in liver problems, hair loss, bone and joint pain, loss of appetite
What does Vitamin D help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with absorption of calcium, bone formation and teeth strengthening
Deficiency = Rickets (Children), Brittle bones (adults)
Excess = Widespread calcification of soft tissues, adverse effects to muscles and heart tissue
What does Vitamin E help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with antioxidants, formation of RBC, preserve healthy muscular + nervous system, maintains function of reproductive system
Deficiency = Fatigue, slow wound healing, premature ageing, low fertility
Excess = Fat soluble vitamin overdose - toxic
What does Vitamin E help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with antioxidants, formation of RBC, preserve healthy muscular + nervous system, maintains function of reproductive system
Deficiency = Fatigue, slow wound healing, premature ageing, low fertility
Excess = Fat soluble vitamin overdose - toxic
What does Vitamin K help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with blood clotting
Deficiency = slow blood clotting
Excess = Problems to red blood cells, baby’s brain damage
What does Vitamin B help with?
What are the effects of deficiency?
What are the effects of excess intake?
Vitamin B helps with oxidising carbohydrates, metabolism of carbs, proteins and fatty acids, formation of RBC’s, tissue formation and DNA/RNA synthesis
Deficiency = Anaemia, irritability, fatigue, pernicious anaemia, dry/cracked skin, mouth sores, poor growth, pellagra.
Excess = Nerve problems, they are water soluble so excess is normally excreted via urine
What does Vitamin C help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with forming collagen
Deficiency = Poor collagen formation, scurvy
Excess = N/A
What does Calcium help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with formation of bones and teeth, blood clotting
Deficiency = Rickets, Osteoporosis
Excess = kidney disease, calcification of soft tissues, disruption to the heart
What does Iron help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with making haemoglobin
Deficiency = Anaemia
Excess = N/A
What does Phosphorus help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with formation of bones/teeth, nucleic acid formation, energy (ATP) release in cells
Deficiency = Bone and teeth formation affected, cell respiration and muscle contractions effected
Excess = N/A
What does Sodium help with?
What are the effects of deficiency?
What are the effects of excess intake?
Helps with regulating body fluid balance and nerve impulse transmission
Deficiency = Muscular cramps
Excess = Hypertension, heart disease, stroke, kidney damage
What does SOCRATES stand for and what is it used to assess?
S = Site O = Onset C = Characteristics R = Radiaton A = Associated symptoms T = Timing E = Exacerbating/relieving factors S = Severity /10
Is a sudden or gradual onset of pain more concerning? Why?
Sudden onset pain is more concerning due to it being caused by a potential rupture/tear or torsion e.g. ruptured aneurysm, ectopic pregnancy, torsion of testis/ovarye
What is Gastroenteritis?
Symptoms?
Treatment?
A viral or bacterial infection of the stomach and bowel
Symptoms = Sudden, watery diarrhoea, feeling sick, mild fever, vomiting
Treatment = Drinking plenty of fluids, rest and paracetamol
Why can NSAID’s cause stomach cramps?
NSAID’s reduce an enzyme that preserves mucosal lining in the stomach
What is appendicitis?
Appendicitis is inflammation of the appendix, it becomes full of fluid and can compress surrounding vessels, compromising blood flow and causing ischaemia and necrosis.
This pressure can escalate forcing bacteria and toxins out, abscesses and peritonitis develop and eventually the appendix will rupture.
Rupture can accelerate peritonitis which can be life threatening
What are the symptoms of appendicitis?
Typically starts with central abdominal pain that may come and go. A burst appendix will cause sudden, severe pain
Within hours, pain travels to lower-right abdomen, becoming constant and severe
Positive McBurneys point/Rovsing’s sign
Palpation/coughing/walking can all make pain worse
Other symptoms include nausea, vomiting, lack of appetite, diarrhoea, high temp, flushed face, tachycardia
Check if they have had their appendix removed!!
Why does Positive Rovsings sign indicate appendicitis
It occurs due to irritation of overlying peritoneum, this pulls on the peritoneum that overlaps the appendix causing referred pain
What is pancreatitis?
Pancreatitis is inflammation of the pancreas, it can be acute or chronic
Causes include gall stones, alcohol, idiopathic cause
Gall stones can become stuck at the entrance to the duodenum, blocking the pancreatic duct and triggering pancreatitis
With this, enzymes that digest food are inactive in pancreas but can become active and auto-digest pancreas
It is a medical emergency, mortality increases with age
What are the associated complications of Pancreatitis?
Acute respiratory distress
Diabetes can develop
Infection
Shock
Renal failure
Malnutrition
What is Diverticulitis?
Bulging pouches in the intestinal wall called diverticula can become inflamed and infected. This often occurs due to faecal matter becoming stuck in the pouches
