Steroid, no antibiotics unless positive sputum sample
Common organisms: H. Influenzae [key], Strep Pneumoniae, Maroxella Catarrhalis

51
Q

What happens in T1DM

A

Autoimmune destruction of insulin-producing beta cells of pancreatic islets of Langerhans -> absolute insulin deficiency

52
Q

Diagnosis of DM in Sx patient ? Asx? Why does HBA1C <48 not exclude DM?

A

Symptomatic patient
fasting glucose ≥ 7.0 mmol/l
random blood glucose ≥ 11.1 mmol/l (or after 75g OGTT)
HbA1c >48 (6.5%)

In an asymptomatic patient one of the above must be demonstrated on 2 separate occasions

not as sensitive test as Fasting blood glucose and results can be misleading in conditions whre there is increased RBC turnover

53
Q

Management of T1DM

A

Individual care plan

Insulin: mixture of short and long acting insulin e.g. Novorapid boluses and Detemir BD

Annual reviews: BP, renal function, eye check, foot check

Target HbA1c <48 mmols/mol

54
Q

3 main parts of T2DM management?

A

Blood glucose control

Monitor and treat microvascular complications

Modify RF for CVD – BP, lipids
QRISK

55
Q

Usual initial weight loss target in T2DM? What dietary advice do you give?

A

5-10%

High fibre, low GI carbs, lower sat fat but can include low fat dairy and fish

56
Q

Metformin S/E? Weight change? Hypoglycaemia risk? C/I? How does it work?

A

S/E: GI upset, risk of lactic acidosis if impaired renal function
Weight neutral
No risk of hypoglycaemia
C/I: recent tissue hypoxia, CT contrast within 48h

Increase insulin sensitivity, hepatic gluconeogensis and GI absorption of CHO

57
Q

Metformin and HBA1C >58 next step?

A

Metformin + Sulfonylurea / DPP4i / SGLT2i / Pioglitazone

58
Q

Sulfonylureas

Eg? S/E? Anything to remember? CI? Mechanism?

A

S/E: weight gain, hypoglycaemia, SIADH, peripheral neuropathy
Only effective if some functioning beta cells present
C/I: breast feeding, pregnancy

Bind to beta cell receptors and stimulate insulin release so only effective if you have some functioning beta cells left

59
Q

Poiglitazone

S/E? Anything to remember? C/I? Mechanism ?

A

S/E: weight gain, # risk, bladder cancer
Need LFT monitoring
C/I: heart failure (fluid retention)

PPARgamma receptor aggonist – increases adipogenesis and improves insulin sensitivity

60
Q

SGLT2 inhibitor Egs?

S/E? Mechanism ?

A

‘flozins’: dapaglifozin, canaglifozin
S/E: UTI, thrush, euglycaemic ketoacidosis
Weight loss

Block renal absorption of glucose

61
Q

DPP4 inhibitors eg? Weight? Hypo? Mechanism ?

A

‘gliptins’: sitagliptin, vildagliptin
Weight neutral, no risk of hypoglycaemia

prevents GLP1 degradation and therefore inhibits glucagon secretion

62
Q

Full T2DM treatment pathway

A

Metformin tolerated - HBA1C target 48

Hba1c >58
Dual therapy - HBA1C target 53

-> triple therapy

Triple therapy not tolerated / ineffective
-> BMI<35 - INSLUIN
Bmi>35 GLP1 agonist Eg exenatide

63
Q

GLP1 mimetics eg Exenatide

S/E? CI? Mechanism?

A

S/E: nausea/vomiting, severepancreatitis
Weight loss
C/I: breast feeding, pregnancy

Preserves beta cells, increases insulin secretion and inhibits glucagon

64
Q

Pathway if metformin not tolerated? HBA1C targets?

A

Sulphonyurea (HBA1C target 53) OR DPP4i / pioglitazone (HBA1C target 48)

IF hba1c >58
-> dual therapy
Target 53

If HBA1C >58
-> insulin

65
Q

67 year old man comes into your GP surgery saying he’s been feeling under the weather and has lost his appetite.

He’s been feeling more tired and achey recently but put it down to ‘getting older’. He’s also been feeling generally itchy and has been getting twitchy legs at night.
PMH: HTN

Diagnosis? Common features? Main complication to look out for?

A

CKD
Uraemic features : anorexia, vomiting, restless legs, fatigue, weakness, bone pain, oedema, pruritis, men – impotence, females – amennorhoea., yellow tinge skin – rare!
Main complications to look out for: encephalopathy,

66
Q

RF for ckd

A

Most common causes in the UK: Hypertension, DM
Others: RAS, glomerulonephritis, adult PKD, SLE
20%: unknown cause

67
Q

CKD staging?

When can you diagnose CKD in stage 1 and 2?

A 
1 - GFR >90ml/min with signs of kidney damage on other tests 
2 GFR 60-90 
3a: 40-59 
3b: 30-44
4: 15-29 
5: <15

Can only diagnose CKD in stages 1 and 2 if abnormal U+E, proteinuria or haematuria i.e. evidence of renal damage

68
Q

Eg of a reversible cause of CKD? Management considerations ? When to refer to nephrology? What do you want to check? What if CKD management part of CVD management?
Diet in CKD?

A

Medications, Blockage, Reduced blood flow

Limit progression/complications  target BP 130/80, renal osteodystrophy, CVD

Symptom control -> anaemia, oedema, restless legs

Refer to nephrology when eGFR <30

Want to check PTH, calicum, alk phosphate.
Offer a statin and an antiplatelet to patients with CKD as part of secondary prevention of cardiovascular disease – decreased eGFR is an independent risk factor for CVD.
Diet – avoid foods with high potassium and phosphate,

69
Q

73yr old lady, currently on lisinopril and felodipine, her clinic and ABPM are consistently >150/90. What should be added next?

VIT K, Beriplex

70
Q 
Interpret this ABG:
65 yr old man brought into A&amp;E with an exacerbation of COPD. On 28% oxygen via simple facemask. 
pH 7.35
PaO2 7.3
PaCO2 11.2
HCO3 36.0
A

Type 2 resp failure as bicarbonate is increased

71
Q

What oxygen saturations are the target for COPD patients on oxygen therapy?

Three things that require annual review in a diabetic?

If an asymptomatic patient has an incidental random plasma glucose test done with a result of 12.0 what does the result of his GTT have to be to be diagnosed as diabetic?

A

88-92%
Renal function, hba1c, bp, eyes, feet
>11.1

72
Q

Paeds asthma >5

A

1 SABA
2 SABA +ICS

3 Add long acting B2 agonist (Salmeterol)

4 Consider leukotriene receptor antagonist
Increase dose of inhaled steroid

Add oral low dose steroid (prednisolone) + refer

73
Q

Sodium / Acid / Alkalosis in dehydrations and causes?

A

Metabolic acidosis – Bicarbonate loss in diarrhoea/shock with lactic acidosis

Metabolic alkalosis – Loss of H+ ions from vomiting in pyloric stenosis

Hyponatraemia – Na high Diarrhoea– Child is lethargic and skin feels dry

Hypernatraemia – Water high Diarrhoea – Child is thirsty and skin feels doughy

74
Q

Maintenence fluids

A

4ml/kg/hour for first 10kg
2ml/kg/hour next 10kg
1ml/kg/hour for rest

75
Q

side effects of chemo

A

Tumour lysis syndrome – The breakdown of large numbers of malignanct cells can lead to high urate, phostpahte and potassium serum levels. Urate can cause renal failure and allopurinol/hydration should be used to prevent this.

Bone marrow suppression (can be congenital too) – Anaemia/thrombocytopenia (bruising/bleeding) can be treated with infusions. Neutropenia needs broad spec antibiotics at any sign of infection.

Long term – Subfertility, nephrotoxicity, deafness, pulmonary fibrosis, cardiomyopathy.

A

Carbimazole

Radioactive iodine
