Pituitary adenoma (cushings’s disease)
Drugs is most common cause (steroids)
If no asthma signs and ipratropium not working what to do
Stop the SAMA (ipratropium)
Start LAMA and LABA so tiotropium and formoterol
LAMA and SAMA work on the same receptors
Also add salbutamol ?
Crypt abscesses which GI problem
Ulcerative colitis
Goblet cells and granulomas, villus atrophy are coeliac
Which antihistamines are sedating and non-sedating
Clhlorphenamine is sedating
Cetirizine, fexofenadine and loratadine are non sedating
Which test determines whether kidney injury is acute or chronic
If hypocalcaemic it is chronic
How to manage bilateral adrenocortical hyperplasia vs adrenal adenoma
Hyperplasia treat with spirinolactone (aldosterone antagonist)
Adenoma treat with surgery
How to treat trigeminal neuralgia
Carbemazepine is first line
Neuro referall if that doesn’t work
How to differentiate lambert Eaton and myasthenia gravies
Lambert Eaton usually gets a bit better with muscle use, MG worsened
MG affects the face and arms earlier, then legs
LES affects legs
What size of AAA requires what monitoring
3-4.5cm = every 12 months USS
4.5-5.5 = every 3 months USS
>5.5cm= 2ww to vascular surgery
Breastfeeding with HIV
No
What condition is carbimazole used to treat
Propanolol initially to help with Sx
Then if graves
Then carbimazole
How to treat mild/ moderate UC flares vs severe
Mild/moderate treat at home with topical (rectal) aminosalicylate -> add oral if that doesn’t work
Severe colitis treat with IV steroids -> add IV cyclosporine if that doesn’t work
Which cardiac abnormality occurs with high calcium
Short QT
Same with high k+
And the opposite is true for low of both
Triad of budd-chiari syndrome,e
Sudden onset abdominal pain
Ascites
Tender hepatomegaly
How to manage idiopathic intracranial hypertension
Weight loss
Carbonic anhydrase inhibitors e.g. acetazolamide
Can also use topiramate which helps with WL also
Which seizure Types do you not give sodium valproate
Focal seizure (partial) give lamotrigine or levetriacetam
Absence seizures (petit mal) give ethosuximide
How do discern between anaemia of chronic disease and IDA from iron studies
Total iron binding capacity (body’s ability to take in iron)
High in IDA as there’s no iron
Low/ normal in AOCD as the body is storing iron outside of the blood so no free space
How to diagnose chronic pancreatitis
CT pancreas
Which type of prostate drug is likely to cause gynaecomastia
GnRH agonists e.g. goserelin
Not doxazosin as much but i think it still can
Which diabetes drug causes weight gain
Sulphonylureas e.g. gliclazide
Why could u do an ECG before starting SSRIs or TCIs
Risk of prolonged QT syndrome
So can do a baseline ECG
Seen more in higher dose
Severe acute alcoholic hepatitis Mx
Glucocorticoids e.g. pred in acute episode
Pentoxyphylline is also sometimes used
Which BP drug causes ED
Indapamide or other thiazide-like diuretics
Which clotting screen does warfarin affect
PT (prolongs it )
No effect on APTT
Because warfarin reduces F7 levels which is in the extrinsic pathway afffecting PT but nt the intrinsic pathway which affects APTT
How to differentiate between gastric and duodenal ulcer
Gastric worse on eating
Duodenal better on eating
As when eating the sphincter is closed between the stomach and duodenum so no acid in duodenum and all in stomach
Lyme disease Mx
If caught early then 14-21daycourse of oralodxycycline
IV cef when there is CNS involvement
What should all people with peripheral artery disease be taking
Statin 80mg
Clopidogrel
what us Chvostek’s sign
Twitching of facial muscles on percussion
Classic indication of hypocalcaemia
E.g. after thyroid surgery, damage to PT gland
What rate should maintainance fluids be prescribed at
30 ml / kg / DAY
So someone who weighs 75kg needs 2250mls over 24 hours
So they need 93.75 ml/hr aka 100 ml/hr
What is a normal anion gap
8-14
On pass med it says 10-18
How do you investigate a suspected perforated duodenal ulcer
Erect CXR
As you can see pneumoperitoneum
Which is suggestive of the above
Which analgesic is first line in renal colic pain
IM diclofenac 75mg
In less severe pain you can do rectal or oral route
How to manage alcohol withdrawal in those with and without liver cirrhosis
Without cirrhosis= chlordiazepoxide (long-acting benzodiazepine)
With cirrhosis= lorazepam (metabolism less affected by liver dysfunction)
How to discern between IgA nephropathy and post-streptococcal glomerulonephritis
IgA nep is shorter word so comes on after 1-3 days of infection
Post-strep glom is longer so comes on 1-2 weeks after infection
Which t2dm meds can cause pancreatitis
DPP-4 inhibitors e.g. gliptins e.g. sitaliptin
UC is linked with which liver problem and how do we diagnose it
Linked with primary sclerosing cholangitis
Diagnose with ERCP or MRCP (ERCP is endoscopic and MRCP is MRI scan)
Which blood pressure med messes with thyroid levels
Amiodarone
Can cause hypo and hyperthyroid
4 drugs that cause idiopathic intracranial hypertension
Tetracyclines e.g. doxycycline
Isotretinoin
Contraceptives
Steroids
Also levothyroxine, lithium, cimetidine (for ulcers)
Hello how do you manage thyrotoxic storm
Beta blockers
Propylthiouracil
Hydrocortisone
How do you investigate hyperadrenalism vs adrenal insuficiency
Hyper e.g. Cushing = dexamethasone supression test
Hypo e.g. addisons = ACTH stimulation test (short Synacthen test)
Ischaemic stroke management outline
1) exclude haemorrhage with CT head
2) Aspirin 300mg OD for 2 weeks
3) if presents <4.5 hours then thrombolysis with alteplase (or <9 hours sometimes)
4) if proximal ant circ (or sometimes prox post circ) and presents <6 hours then thrombectomy, consider thrombectomy <24 hours if salvageable tissue
