Q

What is Klinefelter’s syndrome? how may it present?

A

karyotype 47XXY, is associated with primary hypogonadism in patients with male external genitalia
-tall stature, low-volume testes, sparse pubic hair, and gynaecomastia.

Q

What are the common side effects of imipramine, and what drug class is it in?

A

Tricyclic antidepressant

“can’t pee, can’t see, can’t spit, can’t sh*t”

As well as 5-HT and NA, tricyclics interact with number of other receptors that contribute to their side-effect profile:
antagonism of histamine receptors-drowsiness
antagonism of muscarinic receptors-dry mouth
-blurred vision
-constipation
-urinary retention
antagonism of adrenergic receptors- postural hypotension
-lengthening of QT interval

19
Q

What is Budd-Chiari syndrome? and its classical features?

A

Budd-Chiari syndrome, or hepatic vein thrombosis, is usually seen in the context of underlying haematological disease or another procoagulant condition.

The features are classically a triad of:
abdominal pain: sudden onset, severe
ascites → abdominal distension
tender hepatomegaly

20
Q

Causes of Budd-chiari syndrome and investigations?

A

Causes
polycythaemia rubra vera
thrombophilia: activated protein C resistance, antithrombin III deficiency, protein C & S deficiencies
pregnancy
combined oral contraceptive pill: accounts for around 20% of cases

Investigations
ultrasound with Doppler flow studies is very sensitive and should be the initial radiological investigation

21
Q

What is acute intermittent porphyria?

A

deficiency of one of the enzymes needed to synthesise haem.

22
Q

Symptoms of acute intermittent porphyria?

A

The classical presentation is a combination of abdominal, neurological and psychiatric symptoms:
abdominal: abdominal pain, vomiting
neurological: motor neuropathy
psychiatric: e.g. depression
hypertension and tachycardia common

23
Q

How is acute intermittent porphyria diagnosed?

A

classically urine turns deep red on standing
raised urinary porphobilinogen (elevated between attacks and to a greater extent during acute attacks)
assay of red cells for porphobilinogen deaminase
raised serum levels of delta aminolaevulinic acid and porphobilinogen

24
Q

Management of acute intermittent porphyria?

A

Management
avoiding triggers - e.g. nitrofurantoin
acute attacks
IV haematin/haem arginate
IV glucose should be used if haematin/haem arginate is not immediately available

25
Q

What is Still’s disease?

A

Adult-onset is a Diagnosis of exclusion has a bimodal age distribution - 15-25 yrs and 35-46 yrs

arthralgia
elevated serum ferritin
rash: salmon-pink, maculopapular
pyrexia
typically rises in the late afternoon/early evening in a daily pattern and accompanies a worsening of joint symptoms and rash
lymphadenopathy
rheumatoid factor (RF) and anti-nuclear antibody (ANA) negative

26
Q

Management of adult onset still’s disease?

A

Management
-NSAIDs should be used first-line to manage fever, joint pain and serositis
they should be trialled for at least a week before steroids are added.
-steroids
-may control symptoms but won’t improve prognosis
if symptoms persist, the use of methotrexate, IL-1 or anti-TNF therapy can be considered

27
Q

What is Sheehan’s syndrome?

A

hypopituitarism caused by ischemic necrosis due to blood loss and hypovolaemic shock.
Features may include:
agalactorrhoea
amenorrhoea
symptoms of hypothyroidism
symptoms of hypoadrenalism

28
Q

A 15 y/o girl with family hx of hereditary spherocytosis- what is the most likely cause of episodic upper abdominal pain?

A

Biliary colic

29
Q

If a patient has suspected PE and renal impairment what investigation should be used?

A

Ventilation-perfusion scan
as this avoids nephrotoxic contrast of CTPA

30
Q

Spot diagnosis:
Sudden onset-
Left eye down and out, pupil fixed and dilated
Reduced power on the right side

A

Weber’s syndrome- the branches of the posterior cerebral artery that supply the midbrain are affected.

Sudden-onset neurological deficits (weakness and oculomotor palsy) strongly suggestive of a stroke.

patient has an ipsilateral oculomotor nerve palsy and contralateral weakness of the upper and lower extremity, meaning they have Weber’s syndrome.

31
Q

What medication can be given following a stroke if clopidogrel isn’t tolerated?

A

Aspirin and dipyridamole

32
Q

What can be offered in gonorrhoea if the patient refuses IM ceftriaxone?

A

oral cefixime + oral azithromycin

33
Q

Indications for haemodialysis?

A

AEIOU
Acidosis
Electrolyte abnormalities
Intake - drug over dose
Overloads (oedema)
Uraemia

Drugs SLIME
Salicylates
Lithium
Isopropanol
Methanol
Ethylene glycol

34
Q

How to calculate number needed to treat for a drug?

A

NNT = 1 / Absolute Risk Reduction.
Calculate event rate in trail and placebo group e.g 30/300=0.1
and 60/300=0.2

0.2-0.1=0.1

1/0.1=10=NNT

35
Q

What is Conn’s syndrome?

A

primary hyperaldosteronism, refers to the excessive secretion of the hormone aldosterone.
Normal renin levels

36
Q

Symptoms of Conn syndrome?

A

UNCONTROLLABLE
BLOOD PRESSURE
* EXCESSIVE THIRST
* ^ URINARY FREQUENCY
* ^ NOCTURIA
* MUSCLE CRAMPS
* WEAKNESS or TINGLING
* DIZZINESS
* BLURRED VISION
* HEADACHES

37
Q

Causes of Conn syndrome?

A

ALDOSTERONE-PRODUCING ADENOMAS
BILATERAL ADRENAL HYPERPLASIA

38
Q

Tx of Conn syndrome?

A

aldosterone-producing adenomas and other adrenal tumours may be surgically removed laparoscopically,

Bilateral adrenal hyperplasia can be treated with medications that inhibit aldosterone, such as spironolactone.

In most cases, individuals are also recommended to maintain a low-salt diet, stop smoking, limit alcohol intake, and exercise regularly.

39
Q

Treatment of invasive diarrhoea?

A

Ciprofloxacin

40
Q

What is invasive diarrhoea?

A

Gastritis causing bloody diarrhoea and fever

41
Q

Which organism causes desaturation on exercise?

A

Pneumocystis jirovecii

42
Q

What is Lemierre’s syndrome?

A

Caused by a primary infection in the oropharyngeal region.
If left untreated can spread to the carotid sheath which contains the internal jugular vein (IJV).
-can cause a thrombus to be formed and then septic emboli occur which typically goes to the lungs, liver, and other areas in the body.
