Q

Obstructive Lung Diseases:

What is/are the defenition, site, pathology, aetiology, clinical features, histological features and complications of Asthma?

A

Asthma

DEFINITION: Chronic airway inflammation characterized by intermittent airway obstruction + hyper-reactivity

Site: Bronchi

Aetiology: Genetic + environmental

Pathology: SM cell hyperplasia, excess mucus, inflammation

Clinical presentation: Presents with wheezing, acute SOB, cough [sx worse @night/morning]

Complications: Chronic asthma, Death [severe attack, patients develop status asthmaticus and go into acute respiratory failure]

Note (understanding only): Status asthmaticus is considered a medical emergency. It is the extreme form of an asthma exacerbation= respiratory failure + death

  2. Tracheal and bronchial stenosis
  3. Congenital cysts
41
Q

Congenital lung diseases - Lung agenesis or hypoplasia causes + presentation?

A

Lung agenesis or hypoplasia

  • Low weight or underdeveloped lung e.g. this could be due to compression through a diaphragmatic abnormality
  • Impaired foetal respiratory movements (movement is important in lung development)
  • Very often, these patients present with poor respiratory function after birth

Obstructive lung disease - Asthma presentation - when are sx worst and what is a severe attack called?

A
44
Q
A
45
Q

Asthma Pathophysiology?

A

The first step is sensitisation to an allergen

A patient is exposed to a pollen allergen

Dendritic cells in the airways take up this antigen and present to Th2 cells, activate B-cells = proiduction of allergic IgE antibodies which sit on the surface of mast cells and eosinophils [[∴ type 1 hypersensitivity reaction]

When exposed to the antigen after subsequent sensitisation, there is an immediate phase reaction

There is cross-linking of antibodies on the surface of mast cells when in contact with the antigen

This leads to a massive release of inflammatory mediators which have a number of local effects that cause the initial asthma attack.

  • Granules contain - histamine, leukotrienes, prostoglandins,
