Q

A 23-year-old woman presents with dysuria, malaise, vaginal pain, fever, and myalgia. She consents to a vaginal examination which reveals multiple painful ulcerations around the vagina and perineum. Urinalysis reveals trace leukocytes, no nitrites, and microscopic haematuria. Swabs are taken and sent and a urine MCS is also sent.

Given the most likely diagnosis, what is the most appropriate treatment?

A

This woman has genital herpes. The painful nature rules out lymphogranuloma venereum.

Therefore it is a Genital Herpes caused by HSV-1 which requires an antiviral for 10 days.

Q

A 38-year-old woman presents with a litany of symptoms that have been ongoing for the past four months. These include weight gain, which particularly bothers her around the abdomen, with troubling purplish stretch marks, thin skin and easy bruising. She has been noticing increased swelling in her ankles and poor mood. In the diagnostic work-up, a range of laboratory tests is taken.

What is the expected electrolyte abnormality in this patient?

A

This woman has Cushing’s Syndrome.

The elevated cortisol is due to ectopic production or exogenous sources.

Cortisol may simulate aldosterone thus increased sodium reabsorption, potassium excretion. At high levels of potassium excretion, bicarbonate is absorbed.

This results in a metabolic alkalosis that is hypokalaemic thus Hypokalaemic metabolic alkalosis.

Q

A 68-year-old male presents to the Emergency Department with a two-hour history of crushing left-sided chest pain radiating to the jaw. He has a past medical history of dyslipidaemia and hypertension. You perform an electrocardiogram and serum troponin which confirm an anterior ST-elevated myocardial infarction (STEMI). The nearest primary percutaneous coronary intervention (PCI) centre is three hours away by ambulance and urgent fibrinolysis is therefore given in preference to PCI.

What is the most appropriate management plan regarding myocardial revascularisation of this patient?

A

Take ECG 60-90 minutes later and if no correction, transfer for PCI

Why might a magnet be placed over an ICD?
In the event that you are unclear whether an ICD has been deactivated, placing a large magnet over the device will temporarily deactivate the defibrillation function for the duration of time the magnet is in place. The magnet should therefore be securely taped over the ICD to prevent it slipping off the patient’s chest. If it turns out the ICD has been deactivated, the magnet will do no harm and can simply be removed once it is confirmed deactivation has taken place.

55
Why may Glycopyrronium be preferred to Hyoscine hydrobromide?
Hyoscine hydrobromide is an antimuscarinic drug which will also dry secretions, it can cross the blood-brain barrier and cause agitation, so glycopyrronium might be preferable.
56

Jenna is an 18-year-old woman who was initially admitted with a fever and disseminated rash. She had not been previously vaccinated and was in contact with her 2-year-old cousin who had developed a fever and disseminated blisters and vesicles containing clear fluid. She began to have a fever and flu-like symptoms 2 weeks after seeing her cousin. Similar clear-fluid filled vesicles and blisters developed 3 days later and she was admitted for further observation. After 3 days, she noticed that while most of her skin lesions are healing, one of the lesions on the thigh appears to be red and becoming hot to touch. An area of skin approximately 3x3cm was erythematous. The skin was marked and she was commenced on IV flucloxacillin. Over the coming 12 hours, the erythema around this lesion continued to spread. The pain around her leg increased in intensity, requiring morphine to take the edge off the pain. A blueish discolouration begins to develop around the rash. Given the likely complication that has developed, what is the likely organism that has caused the complication?
GAS

76
A 32-year-old woman comes to surgery for her blood results. She is 25 weeks pregnant and has had her glucose tolerance test. The results are as follows: Fasting glucose = 7.3 mmol/L 2-hour glucose 8.5 mmol/L What would be the most appropriate next step?
Fasting glucose > 7 thus insulin immediately If fasting glucose < 7 then 1 week trial of diet and exercise may be given
77
A 43-year-old man is attending today following a referral from his GP. He has a history of poorly controlled hypertension and has come in today to have his aldosterone: renin ratio performed. The results showed high aldosterone and low renin levels. The patient also has a CT scan which shows bilateral hyperplasia of the adrenal glands. How should this patient be managed?
This patient has a high aldosterone : renin ratio therefore there is elevated levels of aldosterone which feeds back to suppress renin. Aldosterone levels increase sodium retention and potassium secretion thus hypertension occurs. The cause is bilateral thus surgery not indicated, but something to antagonise the effects of aldosterone hence Spironolactone
78
A 29-year-old woman presents to the GP with her mother. She has been experiencing fatigue for 2 weeks which she says is unusual for her.

An 85-year-old man is bought into hospital after developing severe abdominal pain at home. His family report that he has also seemed more confused today and is 'off his legs'. On examination, his abdomen is full with a large palpable bladder. A PR examination reveals a smooth, mildly enlarged prostate with an empty rectum. A bladder scan shows 1L of urine in his bladder. His most recent prescription shows that he takes aspirin, fexofenadine, ramipril, paracetamol, prazosin and insulin. What medication is most likely to have contributed to this presentation?
Fexofenadine - may cause urinary retention
