Q

How can PDR lead to blindness? [4]

A
  • New blood vessels are very fragile; easily break and leak
  • Retinal haemorrhage can lead to acute blindness
  • If repeated; leads to fibrosis & scarring
  • Can lead to: tractional retinal detachment: when scar tissue or other tissue grows on your retina and pulls it away from the layer underneath

Q

What is the management of diabetic retinopathy? [5]

A

Laser photocoagulation

Anti-VEGF medications such as ranibizumab, bevacizumab & Aflibercept

Vitreoretinal surgery (keyhole surgery on the eye) may be required in severe disease or a vitrectomy may be necessary to clear severe vitreous hemorrhage or to relieve tractional retinal detachment.

Corticosteroids: (triamcinolone, dexamethasone implant) can also be used, particularly in refractory DME.

Pan-retinal photocoagulation (PRP): laser used to make small burns evenly across the peripheral retina - should make blood vessels shrink and dissapear

Q

What is the most common cause of visual loss in patients with diabetes? [1]

Describe this [1]

A

Diabetic macular oedema (DMO)

DMO is the commonest cause of visual loss in patients with diabetes

DMO is characterised by oedematous changes in or around the macula. As the macula is responsible for central vision, affected patients tend to complain of blurred vision when reading or difficulty recognising faces in front of them. DMO is the commonest cause of visual loss in patients with diabetes.9

Q

Treatment of mild [2], moderate [2] and severe [4] hypoglycaemia?

A

Mild:
 Sugary drink, e.g. lucozade, ordinary coke, orange juice
 5-7 glucose tablets, or 3-4 heaped teaspoons of sugar in water

Moderate:
Glucogel® – 1-2 tubes buccally (into cheek), or jam, honey, treacle massaged into the cheek.
Intramuscular glucagon if needed

Severe (unconscious)
 Do not put anything in the mouth
 Place the person in the recovery position Administer 0.5-1mg glucagon IM
 If carer is unable to administer glucagon, call 999
 In hospital, administer iv glucose:
- Ideally 75mls of 20% glucose or 150mls 10% glucose over 15 mins
- 50mls 50% glucose can be given, but take care with veins – extravasation can cause chemical burns

Name this complication of diabetic retinopathy [1]

A

Diabetic retinopathy is one of several causes of neovascular glaucoma: a type of secondary glaucoma.

Neovascularization can occur within the iris and its trabecular meshwork (rubeosis) causing a narrowing and closure of the drainage angle and therefore increased intraocular pressure.

Thiazide like diuretics [1] Lithium [1] Tertiary hyperparathyroidism [1]
26
How do you treat hyperparathyroidism? - Surgically? [1] - Therapeutically? [1]
 **Parathyroidectomy**  **Cinacalcet** directly lowers parathyroid hormone levels by increasing the sensitivity of the calcium sensing receptors to activation by extracellular calcium, resulting in the inhibition of PTH secretion. Indicated in patients with: - **Chronic renal failure** - **Tertiary hyperparathyroidism**
27
How do you treat ptx with hypocalcaemia: With < 1.9 Ca2+, no symptoms? [2] With < 1.9 Ca2+, symptoms? [2]
 < 1.9 with no symptoms -  **Oral calcium supplements** -  If due to severe vitamin D def, treat with **high dose vit D** (Calcitriol)  < 1.9 with symptoms -  **IV calcium gluconate**
28
How does renal artery stenosis cause HTN? [2]
- **Atherosclerosis** or fibromuscular dysplasia most causes narrowing of the renal arteries - The chronic ischemia produced by the obstruction of renal blood flow leads to adaptive changes in the kidney which include the **formation of collateral blood vessels and secretion of renin by juxtaglomerular apparatus**

36
Explain specific change in blood flow from portal hypertension contributes to hepatic encephalopathy [1]
**Collaterals** between s**plenic and renal veins**: **spleno-renal shunts**: allow blood from bowel to bypass the liver and leak into systemic circulation, ammonia included (instead of being converted to urea and excreted). Goes to brain
37
How does portal hypertension lead to ascites? [5]
- Increased pressure in portal system causes fluid to leak out of the capillaries in the liver and into peritoneal cavity. Increase in pressure also causes release of splachnic vasodilators. - Drop in circulating volume due to vasodilators on splachnic vessels and fluid forced out causes reduced pressure in kidneys - Renin is released - Aldosterone is secreted via RAAS - Increased aldosterone increase Na+ and therefore fluid reabsorption - Cirrhosis is causes low albumin levels, which decreases oncotic pressure

43
What is dialysis dysequilibrium syndrome? [1]
As urea doesn't leave the BBB as quick so you have excess urea in the brain but lower in circulation so there is a shift of water into the brain **causing cerebral oedema**

Sickle cell disease causes a **normocytic anaemia with raised reticulocyte count** - due to haemolysis
45
What is the treatment of nephrogenic DI? [1]
**Thiazide like diuretic**: - In simple terms DI leads to the production of vast amounts of dilute urine which is dehydrating and raises the plasma osmolarity, stimulating thirst. The effect of the thiazide causes more sodium to be released into the urine. This lowers the serum osmolarity which helps to break the polyuria-polydipsia cycl

54

55
How can you distinguish between a fibroadenoma and phyllodes tumour? [2]

A patient has A 65 year old man presents to the district nurse clinic with acute urinary retention secondary to an enlarged prostate. An immediate urinary catheterisation is attempted and the volume post-catheterisation is recorded as 1200ml. Explain what the next appropriate management is [1]
This patient has a large retention volume of >1000ml. **He should be admitted to monitor for post-obstructive diuresis** - Patients will be at risk for dehydration and **should be monitored closely for their urine output in the hospital and if >200ml/hr urine is being produced**, they should be replaced with intravenous fluids to **avoid acute kidney injury.**
57
How do you differentiate between ASD and VSD based off their murmurs? [2]

**more than 120mls of frank blood in 24 hrs**
67
Which drug should be avoided when giving levothyroxine as it reduces the effectiveness? [1] How do you alter dosing timing to alleviate this? [1]
**Ferrous sulphate** should not be taken at the same time as Levothyroxine as the **iron interferes with levothyroxine absorption.** The two medications should be taken **about 2-4 hours** **apart** with the Levothyroxine taken first.
68
Explain the change in JVP waveform you see in tricuspid regurgitation
**Big v waves** - Tricuspid regurg happens during ATRIAL DIASTOLE, and means some blood moves from the ventricle to the atria filling it even more, and sending more of an equal and opposite force upwards to the internal jugular vein hence why we see prominent v waves.
69

23. A 45-year-old man presents with a carcinoma 10cm from the anal verge, he has completed a long course of chemoradiotherapy and has achieved downstaging with no evidence of threatened circumferential margin on MRI scanning. What is the most appropriate colonic resction for this patient?
**Anterior resection with covering loop ileostomy** - 'carcinoma 10cm from the anal verge' implies that the anus is unaffected by the cancer. **Abdominal-perineal excision of rectum is only used when the anus is involved.** Low rectal cancer is usually treated with a low anterior resection. Contraindications to this include involvement of the sphincters (unlikely here) and poor sphincter function that would lead to unsatisfactory function post resection. Most colorectal surgeons defunction resections below the peritoneal reflection as they have an intrinsically high risk of anastomotic leak. A loop ileostomy provides a safe an satisfactory method of defunctioning these patients. A contrast enema should be performed prior to stoma reversal.

If not already there, patients are transferred to the local on-call dissection centre. Emergency open surgery is typically required, management depends on the exact pattern of findings but may consist of root replacement and valve repair or replacement. **Infective endocarditis**: - management depends upon pattern of valvular involvement (multiple valves may be affected) and complications (e.g. annular/aortic abscess, septic emboli). Coronary angiogram may be performed in selected stable patients prior to operative management. AR is generally an indication for early surgery. -
