Q

Laryngo-tracheo-bronchitis?
Caused by?

A

Usually caused by viral such as measles + parainfluenza

Q

Influenza?

How do they always change ?

A

Orthomyxovirus A/B
Antigens are H and N
H = Haemogluttin -> for ADHESION
N = neuraminidase -> breaching mucosal membrane

Vulnerable to secondary bacterial opportunistic infection such as PNEUMONIA

Change because of ANTIGENIC DRIFT (of the H and N)

Q

Epidemiology of asthma

A

M>F in childhood BUT M=F in adults
Most common in first decade

22
Q

Causes of asthma
Extrinsic?
Intrinsic?
Additional?

A

Extrinsic:
House dust mite faeces
Pollen
Cat, dog, pets

Intrinsic:
Increased sensitivity due to raised igE levels
Bronchial hyper-reactivity

Short arm of chromosome 11

Additional:
Cold air
Exercise
Stress
Pollution
Infection
Drugs eg NSAIDS, B BLOCKERS
Diet

23
Q

Pathogenesis of asthma

A

Oedema
Bronchoconstriction
Increased mucus secretions

Mediated by
Mast cells - release histamine
Lymphocytes

24
Q

Symptoms of asthma

A

SOB
WHEEZE
cough
Symptoms worse in the morning

25
Q

Signs of asthma

A

Quieting of voice and shortness of sentences
Increased EXPIRATORY time
Decreased FEV1/FVC
Hyperinflation
Barrel chest

26
Q

Test for asthma

A

No single test but there are a range of tests can do

27
Q

Management of asthma

A

Education - medication use
Prevention - avoid allergens
Therapy :
sodium chromoglycate - mediates mast cells
B 2 adrenoceptor agonist - bronchodilator

28
Q

What is it common to have from inhalers?
How can you get over this?

A

Oral candidiasis (oral thrush)
(White marks+fungal)

Can get over this by using a spacer

29
Q

What are two types of chronic obstructive airway diseases?

A

Chronic bronchitis
Emphysema

30
Q

What is chronic bronchitis

A

Bronchi inflamed
Obstruction by narrowing airway lumen
Oedema
Excess mucus
Airflow limited
Cough produces sputum (fleghm) for 3 months of 2 successive years

Epithelial cell layer can ulcerate and heal as squamous epithelium (metaplasia)

31
Q

What is emphysema

A

Alveoli are damaged

Dilatation of air spaces by wall destruction

Obstruction by decreasing lungs elastic recoil that golds airways open in expiration -> expiratory airflow limitation

32
Q

Aetiology and pathogenesis of chronic obstructive airway diseases?

A

Smoking
Atmospheric pollution
Alpha 1 anti trypsin deficiency

33
Q

Symptoms of chronic obstructive airway diseases

A

Cough
Sputum
Wheeze
Dyspnoea

34
Q

Signs of chronic obstructive airway diseases

A

Hyperinflation
Quiet breathing sounds
Wheeze

35
Q
A
36
Q

Risk factors for chronic obstructive airway disease

A

Smokers

People who live in dusty environment

People who live in polluted environment

37
Q

Blue bloater vs pink puffer

A

Blue bloater = BRONCHITIS

Pink puffer = EMPHYSEMA

38
Q

Cystic fibrosis

Complication

Treatment

A

INHERITED

Autosomal recessive
Mutation on CFTR gene

Affects lungs and digestive system

Heavy thick sticky mucus - blocks airway passage

Complication - respiratory failure
Pneumothorax

Treatment - stop smoking
Drug therapy

39
Q

Bronchiectasis

A

Dilatation of bronchi

Dilatations caused by inflammation eg:
Measles
Obstruction
Congenital

40
Q

What are examples of lung parenchyma

A

Pneumonia
Lung abscess

41
Q

Pneumonia

A

Inflammation of substance of the lung

Usually bacterial
Can be viral or others

42
Q

What are the types of pneumonia

A

(A) LOBAR pneumonia - affects 1 lobe
BRONCHIAL pneumonia - affects lobules and bronchi

(B) By causative organism:

  • community acquired eg strep pneumonia
  • hospital acquired
43
Q

Risk factors of pneumonia

A

Smokers
Immunocompromised
Underlying lung disease

44
Q

Signs and symptoms of pneumonia

A

Pyrexia
Cough -DRY OR RED SPUTUM /fhlegm

45
Q

Aspiration pneumonia

A

(From Google - inflammation when food/liquid breathed into airways or lungs instead of being swallowed)

Aspiration of gastric acid into lungs (Mendelson syndrome)
Often fatal

Associated with period of loss of consciousness - EG DENTAL SEDATION

46
Q

What is a complication of pneumonia

A

Lung abcess

47
Q

Tuberculosis
Affects?
Risk factors?

A

Most common infective cause of death

Affect lungs, lymph nodes and gut

Risk factors- immunocompromised
Diabetics
Alcoholic
Immigrants - Asians
Doctors / nurses

Multi drug resistant tb organisms

48
Q

Pneumoconiosis?
Examples

A

Lung diseases that are caused by inhaling dusts

Pneumoconiosis - coal miners lungs
Asbestosis - brake linings, railway carriage insulation - Asbestos fibres cannot be broken down by macrophages
Silicosis - mining, builders
Berylliosis- electronics

49
Q

Bronchial carcinoma

Aetiology

A

Most common malignant tumour

More men than women

Aetiology - smoking cigarette
Occupation
Air pollution

50
Q

Pneumothorax

A

Collapsed lung
Air in pleural space
Air sucked in but cannot escape

Treatment is chest drain
