Q

Can you make a new diagnosis of IBS (irritable bowel syndrome) in someone over the age of 50 years?

A

You shouldn’t make this diagnosis without first excluding/ considering other causes such as bowel cancer or diverticulosis which are more common with advancing age

Q

If a patient has diarrhoea, what medications should they stop taking until the diarrhoea has resolved and why?

A

ACE inhibitors, NSAIDs and diuretics. If the patient continues to take these drugs whilst they have diarrhoea, they run the risk of developing an AKI.

Side effects such as unscheduled bleeding or return of fertility can last for up to a year on stopping. There is also increased risk of osteoporosis and weight gain is another side effect.

Q

What are the key points about the Ulipristal acetate pill (ellaOne) for emergency contraception?

A

It is a selective progesterone receptor modulator (SPRM). Primary action is by inhibiting or delaying ovulation. More effective than Levonorgestrel and can be taken within 120 hours (5 days) of UPSI as a single dose. EllaOne is usually chosen over Levonorgestrel unless there has been recent progesterone use or the patient has severe asthma

A

If a BP measurement is >140/90 it should be repeated, if the two differ substantially (i.e. ~>20mmHg) a third should be taken. The lower of the last two measurements is taken as the clinic BP.

66
Q

What 2 main types of migraine are there?

A

Migraine with aura (classical migraine)

Migraine without aura (common migraine)

67
Q

Tell me about migraine with aura (classical migraine) and its 2 stages.

A

Prodromal (aura): transient neurological symptoms develop over ~5 minutes and last up to 1 hour. Can be visual, transient aphasia, tingling/numbness or weakness.
Headache: either starts before the end of the aura or within 1 hour of the aura finishing. Lasts several hrs (sometimes more than a day). Often unilateral and often begins in one spot -> generalised. Ass with nausea/vomiting and photophobia.

68
Q

Tell me about migraine without aura (common migraine)

A

The commonest form = recurrent headache associated with N&V. Typically unilateral pulsating headache which is aggravated by physical activity. Can be difficult to differentiate from tension headache. Prodromal symptoms often vague

69
Q

What are the differential diagnoses for a migraine?

A

Tension headache, cluster headache, sinus headache, medication overuse headache, temporal arteritis (GCA), TIA, meningitis, SAH, brain tumour

70
Q

What are some headache red flags?

A

Onset age >50. Worst headache patient has ever had/ very rapid onset (SAH). History of cancer (esp. lung/breast). Headache that gets progressively worse over days (tumour/abscess). Wakes patient at night (tumour). Early morning vomiting (raised ICP). Unilateral loss of power (stroke/TIA). Seizure (tumour). Weight loss (tumour/ cerebral TB). Altered consciousness (meningitis). Fever (meningitis).

71
Q

What should you do if you find a patient has papilloedema?

A

Emergency admission to hospital

72
Q

Outline the general management of migraines

A

Reassure patient, avoid precipitating dietary factors, try different brand of COCP or switch to POP (COCP is CI in classical migraine with aura), simple analgesia e.g. soluble aspirin 900mg or NSAIDs (caution as overuse can lead to analgesic-rebound headache), antiemetics (prochlorperazine or metoclopramide), triptans

73
Q

What is the general mechanism of action of triptans for migraine?

A

They are 5-HT1 receptor agonists

74
Q

How quickly do triptans work in the treatment of migraine attacks?

A

Oral triptans start working within 1 hour; nasal and s/c forms have more rapid onset

75
Q

In which group of patients are triptans contraindicated?

A

Patients with angina or those with high risk of IHD

76
Q

Can you purchase triptan medications over the counter?

A

Yes, sumatriptan (which was the first triptan to come onto the market) is available OTC without a prescription as a 50mg tablet

77
Q

At what point should you consider prescribing migraine prophylaxis for a patient?

A

Consider prophylaxis if >2 attacks per month or if the attacks are particularly severe/prolonged

78
Q

What is the first-line treatment for migraine prophylaxis?

A

Propranolol (providing there are no CIs e.g. asthma or peripheral vascular disease)

79
Q

What drug is 2nd line in the prophylaxis of migraines? And what SEs or cautions are there with its use?

A

Topiramate (an anti-epilepsy drug)
SEs: paraesthesia, impaired concentration and sleep, weight loss
Affects efficacy of contraceptive pills

80
Q

In terms of length of illness time for URTI, how long does it take for 90% of people to recover from the following illnesses? Acute sore throat/pharyngitis/tonsillitis, common cold, acute rhinosinusitis, acute cough/bronchitis.

A

Acute sore throat/pharyngitis/tonsillitis = 1 week
Common cold = 1.5 weeks
Acute rhinosinusitis = 2.5 weeks
Acute cough/ bronchitis = 3 weeks

81
Q

How can you further categorise the symptom of a sore throat?

A

Tonsillitis

Acute pharyngitis- inflammation of the part of the throat behind the soft palate

82
Q

What are the infectious causes for a sore throat?

A 
Common cold viruses e.g. rhinovirus- 25%
Bacteria- most commonly GABHS (group A beta-haemolytic strep)
Influenza
Herpes simplex (HSV-1) 
EBV (peak incidence 15-25 year olds)
83
Q

What investigation(s) can you do if you suspect EBV?

A

Monospot blood test plus FBC and LFTs

84
Q

What is the management of a patient presenting with an acute sore throat?

A

Reassure that most sore throats are self-limiting and resolve within 7 days without antibiotic treatment. Antibiotics should not be prescribed routinely (refer to Centor criteria / FeverPAIN criteria to help make decisions about Abx)

85
Q

NICE advises using one of two criteria to aid diagnosis of GABHS as the cause of a sore throat, and hence guide when it might be appropriate to use Abx- these are Centor and FeverPAIN criteria. Outline the Centor Criteria.

A 
Tonsillitis exudate
Tender anterior cervical lymph nodes 
Absence of cough
History of fever
Presence of 3 or 4 of these signs suggest the chance of having GABHS is between 40-60% so the patient may benefit from Abx Tx.
86
Q

Outline the FeverPAIN criteria

A 
Fever
Pus (exudate)
Attends rapidly (<3 days) 
Inflamed tonsils 
No cough/ coryza 
Each factor scores 1. If score = 0 or 1- no Abx. If score = 2 or 3- delayed antibiotic prescription. If score = 4 or 5 - immediate antibiotics
87
Q

What should you do if a patient who is taking a DMARD drug or carbimazole or is on chemotherapy presents with a sore throat?

A

Arrange an urgent FBC and seek specialist advice- this is due to the risk of neutropenia and agranulocytosis

88
Q

At what point should you consider a non-urgent referral to ENT for tonsillectomy?

A

If 7 or more episodes in 1 year disrupting normal activities (or if 5 or more episodes in 2 years)

89
Q

What is the classic triad of Glandular fever? And what age group is more commonly symptomatic?

A

Classic triad of: fever, acute pharyngitis and lymphadenopathy.
More commonly symptomatic in adolescence/ early adulthood
Tiredness and headache are also common and the fatigue can sometimes persist for 1-2 months

90
Q

What is the management of glandular fever (infectious mononucleosis) and what specific advise should you give people?

A

It is usually self-limiting with no specific Tx required. Supportive care with adequate hydration and analgesics. Up to 50% of people develop splenomegaly and should be advised to avoid contact sports until resolved.

91

Q

When you should refer under the 2ww for suspected lung cancer?

A

A

A CXR- consider lung cancer as a diagnosis

149
Q

If you suspect lung cancer in a patient and the CXR comes back as normal, does this rule out lung cancer as a cause of their symptoms?

A

No as CXRs may be negative even when the patient has cancer. If the CXR is normal and we still suspect lung cancer, we should request a CT scan or refer the patient for a bronchoscopy.
