Asthma Management

A

Step 1

Q

Mesothelioma

builder, chimney , veteran

A

Asbestos exposure
Latent period to develop up to 45yrs
Finger Clubbing (seen in <1% of patients)

Shortness of breath , Chest pain , Weight loss

CT/ CXR - pleural thickening or effusion
(lung cancer does not necessarily show pleural thickening)

Diagnosis - Thoracoscopy - PLEURAL BIOPSY - Histology
(Broncoscopy - Lung malignancy and Pneumocystis jiroveci )

if there is pleural effusion due to mesothelioma -> long term indwelling pleural drainage is the management for the pain relief

Q

Diagnosis of Asthma RM 3941

A

The initial test for 5 to 16 years is spirometry.
A bronchodilator reversibility (BDR) test should be considered if spirometry shows an obstruction.
if diagnostic uncertainty remains after spirometry and BDR, consider a FeNO test.
If diagnostic uncertainty remains after FeNO, monitor peak flow variability for 2 to 4 weeks.

The initial tests for >17 years and over are FeNO followed by spirometry.
A BDR test should be carried out if spirometry shows an obstruction.
If diagnostic uncertainty remains after FeNO, spirometry and BDR,
monitor peak flow variability for 2 to 4 weeks.
If diagnostic uncertainty remains after measuring peak flow variability,

refer for a histamine or methacholine direct bronchial challenge test.
