A 53-year-old female patient presents to the outpatient clinic for her asthma review.
She has been admitted to the hospital three times in the last year with asthma exacerbations. Admission duration was 2-3 days in hospital but never required intubation or intensive care admission. This is on a background of multiple admissions to hospitals in previous years.
On review, she reports wheeze associated with dyspnoea on most days and this is usually triggered by exertion. There is a non-productive cough most mornings which settles throughout the course of the day. There is no history of allergic rhinitis, eczema or other medical problems. She is a life-long non-smoker.
Current asthma therapy is high dose inhaled fluticasone propionate plus salmeterol 2 puffs twice daily, prednisolone 10mg once daily and inhaled salbutamol as required. She has been taking regular prednisolone 10mg for the last eighteen months.
On examination, observations revealed a respiratory rate of 14/min, oxygen saturation of 98% on room air, heart rate 80/min regular, blood pressure 130/70 mmHg and a temperature of 36.8ºC. There is no clubbing, cervical lymphadenopathy or elevation of the jugular venous pressure. Auscultation of the chest revealed dual heart sounds with no murmurs and some mild expiratory wheeze in the upper zones. The calves were soft and non-tender, with no pedal oedema.
You had reviewed this patient during her most recent exacerbation and had arranged some outpatient tests, the results of which are shown below:

2. Hb 14 g/dl,
WBC 8 x 10^9/L (Neuts 4.5 x 10^9/L, Lymphs 1.0 x 10^9/L, Eosin 2.5 x 10^9/L)
Platelets 350 x 10^9/L
Sodium 138 mmol/L, Potassium 3.4 mmol/L, Urea 5 mmol/L, Creatinine 70 mcmol/L
CRP 7 mg/l

Fraction of exhaled nitric oxide – 65 parts per billion (upper limit of normal 50 ppb)

24 / 98

24.

A 62-year-old man sees his GP with complaints of leg pain. Over the last few months, he notices a crampy uncomfortable feeling in the back of both of his calves when he walks to the shops. The discomfort can be so bad that he has to stop and rest for a few minutes after which he notices that his symptoms are improved. On occasions, he also gets the symptoms when he is shopping in the supermarket. He attributes this to overexerting himself, and tries to rest on his shopping trolley while walking but does not seem to help. He has a 40-pack year smoking history and takes amlodipine for his blood pressure, and paracetamol and ibuprofen for lower back pain that has troubled him for years.
Physical examination reveals mild atrophy of his thigh and calf muscles bilaterally, in addition to shiny pale skin with significant hair loss throughout his lower limbs. His pedal pulses are bilaterally impalpable, and popliteal pulses are faint. Power in both lower limbs is normal throughout all movements, and he has normal patellar reflexes bilaterally and absent ankle reflexes. His Babinski reflex is downgoing on the left side and equivocal on the right side. A recently obtained ankle-brachial pressure index test yielded a result of 0.70 on the right side and 0.95 on the left side. X-rays of his lumbar spine show evidence of joint space narrowing and osteophytes.
Which one of the following is the next best step in the management of this patient?

30.

A 60-year-old man presents to his general practitioner a month after a permanent pacemaker (PPM) insertion, which was inserted for symptomatic first-degree heart block. He reports that since this was inserted, he has actually felt worse and his exercise tolerance has become more limited.
An ECG is performed and shows a paced rhythm on VVI at 68/min. Each pacing spike is followed by a QRS complex and there are no pacing spikes in between beats. He has regular P-waves at a rate of 35/min which are not related to the QRS complexes.

31 / 98

31.

A 64-year-old female was admitted to the hospital with a moderate-large sized embolic stroke. She had a history of diabetes and newly diagnosed atrial fibrillation (AF). Her blood pressure on admission was 165/90 mmHg with a heart rate of 95 beats per minute.
An MRI brain was performed 24 hours after admission which showed a moderate to a large area of infarction involving the anterior 2/3rd of the left middle cerebral artery territory without haemorrhagic transformation.

32 / 98

32.

A 68-year-old man is being treated in a medical ward for an empyema. A chest drain was inserted under ultrasound guidance at the time of admission and antibiotics were started. Over the past few days, there have been significant volumes drained and the patient has been improving clinically. On the daily morning ward round, his chest drain is reviewed which is on suction. There is minimal drain output over the past 24 hours, and it is noted that the chest drain is bubbling. This bubbling is more significant when the patient is asked to cough.
What does this indicate?

A 42-year-old with a past medical history of asthma was reviewed by you in the clinic. Asthma was diagnosed in childhood. In adulthood, he has had multiple admissions to the hospital with asthma exacerbations in the summer months and never required intubation and ventilation for these.
He reports a nocturnal cough up to three times per week. There are associated rhinorrhoea and dry eyes that have been present since the weather became a bit warmer. Currently, he is using a salbutamol inhaler every other day for wheeze and mild dyspnoea. He works in construction and finds that his symptoms are worse when he is outside.

56. A 72-year-old woman is brought to ER after she had an episode of loss of consciousness. She gives a history of increasing shortness of breath on exertion. Her past medical history includes a right total hip replacement following a fractured neck of femur about 4 years ago. Otherwise, she is on no regular medication. There are no drug allergies.

A 30-year-old man presents to the emergency department with a four-day history of subjective fevers, shortness of breath, non-productive cough and malaise. On arrival at the emergency department, his observations revealed a temperature of 38.5ºC, heart rate 120/min, blood pressure 90/60 mmHg, respiratory rate 35/min and oxygen saturation of 80% on room air. An arterial blood gas revealed severe type 1 respiratory failure and the patient was intubated and placed on mechanical ventilation.
A post-intubation chest x-ray revealed bilateral pulmonary infiltrates and within the limits of a portable chest x-ray, a normal-sized cardiac silhouette.
Intravenous 1g ceftriaxone, 500mg azithromycin and 200mg hydrocortisone were given in the emergency department for severe community-acquired pneumonia prior to transfer to the intensive care unit (ICU). The patient remained on invasive mechanical ventilation for the first 24 hours. During this time, he underwent computed tomography pulmonary angiography (CTPA) and bronchoalveolar lavage. He made good progress and was extubated to high flow nasal cannulae after 24 hours. He is haemodynamically stable. He is stepped down to the high dependency unit (HDU), where you review the patient.
You speak with the patient’s wife to obtain a collateral history. The patient has no known past medical, surgical, drug or family history of note. He works as a full-time chef and there have been no known sick contacts. He drinks 1-2 cans of standard strength beer per night and occasionally binge drinks at the weekends. He recently started smoking cigarettes to cope with increased stress at work and there is no history of illicit drug use. There has been no recent travel history.
On examination in the HDU, the temperature was 37.5ºC, heart rate 90/min, blood pressure 100/60 mmHg and respiratory rate 26/min. He is on high flow oxygen via nasal cannulae, with a flow rate of 30 litres per minute, the fraction of inspired oxygen is 30% and has an oxygen saturation of 95%. There are fine inspiratory crepitations audible in the lower posterior chest bilaterally which do not change with coughing. The jugular venous pressure was not elevated and there was no pedal oedema.
Current medications are IV Ceftriaxone, Azithromycin and PRN Paracetamol.

A 60-year-old man with metastatic small cell lung cancer is admitted with shortness of breath, cough and purulent sputum.
His chest x-ray shows right lower lobe pneumonia with partial collapse of the right lung. He has a bulky primary tumour at the right hilum and extensive hilar lymphadenopathy.
He is treated with IV antibiotics, fluids and oxygen. His symptoms improve over the next 5 days and his breathing is comfortable on 2 litres of oxygen via nasal cannulae.
