MRCP2-4309

An 80-year-old woman presents with worsening breathlessness and a productive cough. She has a history of exertional dyspnoea for two years, which has recently become more severe. She was a heavy smoker until three months ago and currently takes Beclasone, salmeterol, and Ventolin. On examination, she is obese with a BMI of 32 kg/m2, cyanosed, and pale. She has no clubbing or lymphadenopathy, but her chest is hyperinflated with expiratory wheezes and she has bilateral swollen ankles. After treatment with nebulised bronchodilators, oxygen therapy, prednisolone, antibiotics, and diuretics, she improves and is discharged home. Six weeks later, her arterial blood gas analysis shows a PaO2 of 6.9 kPa and a PaCO2 of 6.8 kPa, and her pulmonary function testing reveals an FEV1 of 0.9 l and an FVC of 4.2 l. What is the primary indication for long-term domiciliary oxygen therapy in this patient?

MRCP2-4301

A 20-year-old Caucasian male presents with a two-day history of epigastric pain accompanied by nausea and vomiting. He was admitted under the surgical team for management of acute pancreatitis due to an elevated serum amylase level. The surgical team has requested a medical consult as the patient reports a worsening productive cough.

During your assessment, the patient reports that this is his third presentation with acute pancreatitis. He does not consume alcohol, and an ultrasound of the abdomen did not reveal any gallstones. The cough has been present for several months, initially dry but now productive of green sputum with no haemoptysis. He denies fever, chills, chest pain, and dyspnoea. Three weeks ago, he received a course of oral antibiotics from his General Practitioner after presenting with nasal congestion and mild facial pain. He states having had multiple courses of antibiotics in the past for similar presentations.

There is no significant past medical history or family history.

The patient takes no regular medications and has been receiving simple analgesia and intravenous crystalloid fluids under the surgical team’s care. He is a lifelong non-smoker and works full time in administration.

On examination, the patient’s height was 178cm with a weight of 58kg, heart rate 90/minute, blood pressure 100/60 mmHg, temperature 37.2ºC, respiratory rate 16/min, and oxygen saturation 94% on room air. Respiratory examination revealed early clubbing, no cervical lymphadenopathy, a central trachea, normal chest expansion, mild coarse inspiratory crepitations that improved somewhat after coughing at both posterior bases. Abdominal examination revealed mild epigastric tenderness but no signs of peritonism. Remaining clinical examination was unremarkable.

Lab results showed Hb 130 g/l, Na+ 136 mmol/l, Platelets 400 * 109/l, K+ 4 mmol/l, WBC 12 * 109/l, Urea 6 mmol/l, Neuts 10 * 109/l, Creatinine 65 µmol/l, Lymphs 1 * 109/l, and CRP 30 mg/l. Chest x-ray was normal.

Sputum microscopy and culture results revealed Pseudomonas aeruginosa.

What is the most appropriate management for this patient?

MRCP2-4303

A 63-year-old man with metastatic small cell lung cancer is admitted with shortness of breath, cough, and purulent sputum. His chest x-ray reveals a right lower lobe pneumonia with partial collapse of the right lung. The right hilum has a bulky primary tumor and extensive hilar lymphadenopathy. He receives IV antibiotics, fluids, and oxygen, and his symptoms improve over the next five days. He is comfortable on 2 liters of oxygen via nasal cannulae and his pain is controlled on 20mg long-acting morphine sulfate twice daily. The decision is made to discharge him to a hospice for end-of-life care. However, due to the proximity of his lung tumor to major vessels, he is at risk of a major terminal bleed. What medication should the hospice be advised to administer in the event of a major bleed?

MRCP2-4302

A 65-year-old man presents to the emergency department with a two month history of productive cough. He reports feeling increasingly worse over the past week and experiencing feverish symptoms. He mentions that he often coughs up large amounts of mucous, but this time it is much worse and he suspects an infection. The patient discloses that he is regularly under the care of the respiratory team for a lung condition, but cannot provide further details. He is a non-smoker.

Upon examination, the patient appears sweaty and has a temperature of 38.2ºC. His heart rate is 103/min and his capillary refill time is 3 seconds. Blood pressure is 102/54 mmHg. Coarse crackles are heard bilaterally and on the right mid-zone. Heart sounds are normal with no added sounds.

A chest x-ray reveals increasing bronchovascular markings with bilateral consolidation.

Reviewing the patient’s medications, it is noted that he is on salbutamol and ipratropium nebulisers, carbocisteine, aspirin, and ramipril. The patient also mentions that he has been taking ciprofloxacin for 14 days as prescribed by the respiratory team due to an organism isolated in his sputum. Upon further investigation, it is discovered that the patient has previously grown Pseudomonas aeruginosa.

Given the patient’s penicillin allergy, what antibiotic would be appropriate to prescribe in this setting?

– Intravenous meropenem
– Intravenous co-amoxiclav
– Intravenous tazocin
– Intravenous metronidazole
– Nebulised colomycin

Answer: Appropriate treatment of Pseudomonas positive bronchiectasis failing to respond to ciprofloxacin includes IV tazocin, ceftazidime, aztreonam or meropenem. Given the patient’s penicillin allergy, the safest choice is meropenem. Nebulised colomycin has a place in the treatment of these patients, but not in the acute setting.
