Treatment with an inhaled corticosteroid (ICS) should be considered for patients with any of the following except?

A 50 year old man with a previous lung transplant develops persistent cough and increasing shortness of breath for the last 3 days.Early inspiratory crackles are heard by lung auscultation. Pulmonary function demonstrates irreversible airflow obstruction with decreased FEV1:FVC ratio and low DLCO The chest radiograph shows normal lungs However the HRCT shows air trapping by the expiratory view, a mosaic pattern, bronchiolectasis and small airway wall thickening.

What is the most likely diagnosis?

A 17 year old man is referred with poorly controlled asthma.He has been taking inhaled Budesonide 400mcg 1 puff twice daily for the past 5 months but continues to have daily wheeze and cough requiring up to ten puffs of Salbutamol/day. Chest X ray shows hyperinflation but otherwise unremarkable.Lung function test shows a moderate obstructive pattern with 93% increase in FEV1 after bronchodilator.

What is the most appropriate next step?

A 30 year old lady with a history of asthma and chronic sinusitis develops worsening shortness of breath and wheezing after ingesting aspirin. She responded to treatment with salbutamol, oral corticosteroids,inhaled fluticasone and montelukast.

The other clinical feature the patient is most likely to have is?

A patient is on long term inhaled corticosteroid for her asthma.

Which complication is most likely to occur?

What is the antibiotic of choice for treating community acquired pneumonia?

What is the most common bacteria isolated in acute exacerbation of COPD?

In a 65 year old male with COPD, which of the following carries the greatest risk of death over the next 12 months?

The BODE index is a useful clinical tool in predicting the risk of death in patients with COPD.

Which of the following parameter is not part of the BODE index?

In patients with COPD, which of the following intervention has the greatest impact on mortality?

An 80 year old man with COPD has ankle edema, raised JVP and breathlessness.ABG shows PO2 of 56mmHg.CXR shows hyperinflated lung fields.

What is the best treatment to improve his survival?

Calculate the A-a gradient of this patient based on the following ABG: Ph 7.49 pCO2 48 PO2 54 HCO3 33
(The atmospheric pressure at sea level is 760 mmHg., the respiratory quotient is 0.8 and the water vapour pressure is 47 mmHg.Fi02 is 0.21.)

Which one of the following is a contraindication to surgical resection in lung cancer?

Which of the following feature is not consistent with the diagnosis of eosinophilic bronchitis?

In patients with COPD, inhaled steroids and LABA have a positive effect on all of the following except?

Which of the following is not an indication for a bronchoscopy in patients with bronchiectasis?

Which of the following lung cancer is most associated with smoking?

A 50 year old smoker is found to have an asymptomatic solitary pulmonary nodule on chest CT.

Which of the following features would be the strongest predictor of malignancy?

Vital capacity is the sum of:

Which one of the following carries a better prognosis in patients with cystic fibrosis?

The following are the criteria for diagnosing a patient with cystic fibrosis except?

Increasing the activity of defective cystic fibrosis transmembrane conductance regulator (CFTR) protein is a potential treatment for cystic fibrosis. A recent randomized controlled trial have demonstrated the efficacy of combination treatment with CFTR modulators elexacaftor, tezacaftor and ivacaftor.

Which group of CF patients will most likely benefit from this combination therapy?

Which of the following is the highest risk factor for developing lung cancer?

What is becoming the most common histological finding in lung cancer especially in females?

A 60 year old lady is referred to your respiratory clinic for advise on further management of her COPD. She is an ex-smoker with a 10 pack year smoking history. She has been complaining of worsening dyspnea over a period of 6 months. This is despite being on maximal medical therapy and following completion of 6 weeks pulmonary rehab program. 

Her latest lung function test is shown below:

• FEV1 of 1.8L, 82% predicted.
• FVC of 2.74L, 96% predicted.
• FEV1/FVC ratio of 0.6
• TLC of >110% predicted, RV of >250 percent predicted.
• DLCO of 50% predicted.

 These are the coronal and sagittal views of her chest CT:

Which of the following factors would make her a less favorable candidate for a bullectomy?
