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

34
Diagnosis of Asthma RM 3941
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.

As he wash his mouth regularly (dont need Nystatin ) Check Spacer technique with his inhaled corticosteroid
39
RM3290 Coughing up for 18 months but only cough a tablespoon(very less)/ Chronic smoker and dyspnea sometime steak of blood . Initial appropriate Inv
Chest X ray (to rule out Lung CA , Bronchiectasis ) if ruled out (COPD) then sent to resp nurse for Spirometry and blood test for polycythemia

41
Broncho pleural fistula
1. Seen in lung cancer more likely in pneumonectomy rather than lobectomy. 2. More common in right side. 3. Coughing of copious amount of brown fluid is pathognomonic for BPF. 4. Diagnosis is confirmed by CT chest. 5. Two X-ray needed with classic finding of drop in the air fluid level. 6. Treatment is by endoscopy, bronchoscopy or open chest surgery.
42
RM 4052 | 85yr , COPD , increasing breathlessness , even on walking , BUT STILL SMOKES , most appropriate tx
