Developmental Aspects of Lung Disease Flashcards
In what stage of morphogenesis does surfactant being to develop
Saccular stage
Common upper congenital abnormalities
Tracheal anagenesis and stenosis
Tracheomalacia
Tracheo-oesphageal fistula
Common lower congenital abnormalities
Lung anagenesis/pulmonary hypoplasia
Bronchogenic cyst
Congenital pulmonary airway malformation (CPAM)
Congenital diaphragmatic hernia
Presenting features in antenatal scanning
Ultrasound - show up more at 20 weeks scan
Presenting features in newborns
Tachypnoea
Respiratory distress
Feeding issues
Tachypnoea
Abnormally rapid breathing
Presenting features in childhood
Stridor/wheeze
Recurrent pneumonia
Cough
Feeding issues
Asymptomatic presenting features
Incidental finding
Tracheal agenesis
Trachea is absent or underdeveloped
Presentation of tracheal agenesis
Acute respiratory distress at birth
Tracheal stenosis
Tracheal cartilage rings are completed too early, may be generalised or segmental
Time of detection of tracheal stenosis
At birth or within first year
Tracheomalacia
Dynamic abnormal collapse of tracheal walls
Presentation of tracheomalacia
Braking cough
Recurrent croup
Breathless on exertion
Stridor/wheeze
Management of tracheomalacia
Physiotherapy and antibiotics when unwell, natural resolution with time
Causes of tracheomalacia
Genetic conditions
External compression
Tracheo-oesphageal fistula
Abnormal connection between trachea and oesophagus
