CAP management

Mild=
If allergic =

Q

In a pleural effusion what is the criteria for a chest tube drainage straight away?

Everyone with…. needs ….

  1. 2
A

All patients with a pleural effusion in association with sepsis or a pneumonic illness require diagnostic pleural fluid sampling:

  1. if the fluid is purulent or turbid/cloudy a chest tube should be placed to allow drainage
  2. if the fluid is clear but the pH is less than 7.2 in patients with suspected pleural infection a chest tube should be placed

Q

Alpha-1 antitrypsin deficiency is a risk factor for which cancer?

A

Alpha-1 antitrypsin deficiency produced in the liver is a risk factor for hepatocellular carcinoma

17
Q

asthma stepping down treatment rules with steroids

A

consider stepping down treatment every 3 months or so.
When reducing the dose of inhaled steroids the BTS advise us to do this by 25-50% at a time.

18
Q

What rash do you get in sarcoidosis and how is different to SLE?

Features = A GRUELLING DISEASE:

A

lupus pernio is a purple nodule or plaque found on the nose, cheek, or lips.

A GRUELLING DISEASE:
ACE increase
Granulomas
aRthritis
Uveitis
Erythema Nodosum
Lymphadenopathy (B/L Hilar)
Lupus pernio
Idiopathic
Noncaseating
Gammaglobulinaemia
vit D increase (hypercalcaemia)

19
Q

Aspergilloma presents with episodic haemoptysis, what do you see on CXR?

Also a past history of…

A

Chest x-ray shows a rounded opacity in the right upper zone surrounded by a rim of air.

PM Hx of TB

20
Q

3 categories and their underlying pathology
category 1 (3)

category 2 (3)

Category 3 (3)

A

assess the position of the trachea - is it central, pulled or pushed from the side of opacification.

Trachea pulled toward the white-out
- Pneumonectomy
- Complete lung collapse e.g. endobronchial intubation
- Pulmonary hypoplasia

Trachea central
- Consolidation
- Pulmonary oedema (usually bilateral)
- Mesothelioma

Trachea pushed away from the white-out
- Pleural effusion
- Diaphragmatic hernia
- Large thoracic mass

21
Q

Indications for corticosteroid treatment for sarcoidosis

A
  1. parenchymal lung disease
  2. uveitis
  3. hypercalcaemia 4. neurological or cardiac involvement
22
Q

In suspected lung cancer should you do contrast or non-contrast CT?

A

contrast-enhanced CT scan of the chest, liver and adrenals.

23
Q

What smoking cessation drugs CAN be given in preg and CANNOT

A

nicotine replacement therapy should be offered,

varenicline and bupropion are contraindicated

24
Q

ARDS- what is it?

Causes (5/7)

Key investigations? (2)

A

Acute, diffuse, inflammatory lung injury and life-threatening condition in seriously ill patients, characterized by poor oxygenation, pulmonary infiltrates, and acute onset

Infection: sepsis, pneumonia
massive blood transfusion
trauma
smoke inhalation
acute pancreatitis
Covid-19
cardio-pulmonary bypass

Investigations
chest x-ray and arterial blood gases

25
Q

-
-
- pO2/FiO2 < ….

Management- usually ITU

A
  • acute onset (within 1 week of a known risk factor)
  • pulmonary oedema: bilateral infiltrates on chest x-ray (‘not fully explained by effusions, lobar/lung collapse or nodules)
  • non-cardiogenic (pulmonary artery wedge pressure needed if doubt)
  • pO2/FiO2 < 40kPa (300 mmHg)
  1. oxygenation/ventilation to treat the hypoxaemia
  2. general organ support e.g. vasopressors as needed
  3. treatment of the underlying cause e.g. antibiotics for sepsis
  4. Put them in a prone position when ventilating (increasing bilteral lung inflation) and muscle relaxation have been shown to improve outcome in ARDS
26
Q

A
  1. have chest x-ray findings that suggest lung cancer
  2. aged 40 and over with unexplained haemoptysis

offer CXR:
>= 40yo with 2 or more from the following list, or if they have ever smoked and have 1 of the following unexplained symp

  • cough
  • fatigue
  • SOB
  • chest pain
  • weight loss
  • appetite loss

Consider CXR
- persistent or recurrent chest infection
- finger clubbing
- supraclavicular lymphadenopathy or persistent cervical lymphadenopathy
