Respiratory Flashcards
Bronchiolitis common pathogen
RSV 80% Parainfluenza Rhinovirus Adenovirus Influenza virus
3 patterns of wheezing
Viral episodic-in response to infection
Multi-trigger- likely to develop into asthma
Asthma
Causes of recurrent/persistent wheeze
Viral episodic wheeze
Multiple trigger wheeze
Asthma
Recurrent anaphylaxis (e.g. in food allergy) Chronic aspiration
Cystic fibrosis Bronchopulmonary dysplasia Bronchiolitis obliterans Tracheo-bronchomalacia
Asthma treatment
SABA ICS >5 LABA. <5 LRTA >5 increase ICS. <5 refer Max ICS 1600 ug. 800 ug for under 5
Criteria for hospital admission: asthma
If after high dose inhaled bronchodilator therapy:
Different types of URTI
commoncold(coryza)
sore throat (pharyngitis,tonsillitis)
Acute otitis media
Sinusitis (relatively uncommon)
Most common pathogen of coryza (common cold)
Rhinovirus
Coronavirus
Respiratory syncytial virus (RSV)
Common pathogens for pharyngitis
Adenovirus
Enterovirus
Group A B-Haemolytic streptococcus
Common pathogens Tonsillitis
Group A beta haemolytic streptococcus
Epstein-Barr virus (infectious mononucleosis)
Treatment of bacterial tonsillitis
Penicillin V or erythromycin m
Acute otitis media pathogens
RSV
Rhinovirus
Pneumococcus
Non typical H.Influenza
Common indications for tonsillectomy
Recurrent severe tonsillitis Peritonsillar abscess (Quincy) Obstructive sleep apnoea
Croup pathogens
Parainfluenza
Rhinovirus
Influenza virus
Croup peak incidence
6 months to 6 years
Peak at 2
Features of croup
Coryza Fever Hoarseness Barking cough Harsh stridor Symptoms often start and are worse at night
Croup first line Tx
Oral steroids
Dexamethasone, prednisolone
Nebulises steroid- budenoside
In severe cases adrenaline with oxygen via face mask
Acute epiglottis
Intense swelling of the epiglottis and surrounding tissues
Caused by Haemophilia influenza type b (HIb)
Acute epiglottis presentation m
High fever in an ill looking child
Painful throat prevents child from speaking or swallowing
Saliva drools from mouth
Soft inspiratory stridor
Child sits immobile upwards with mouth open to breath
Another name for pertussis
Whooping cough caused by Bordtella pertussis.
Pertussis clinical features
Week of coryza Paroxysmal or spasmodic cough Inspiratory whoop Often worse at night may have cough Goes red/blue in the face
Cystic fibrosis
Autosomal recessive disease
Misfolded CFTR
Clinical features of CF
Newborn
• Diagnosed through newborn screening
• Meconium ileus
Infancy • Prolonged neonatal jaundice • Growth faltering • Recurrent chest infections • Malabsorption, steatorrhoea
Young child • Bronchiectasis • Rectal prolapse • Nasal polyp • Sinusitis
Older child and adolescent • Allergic bronchopulmonary aspergillosis • Diabetes mellitus • Cirrhosis and portal hypertension • Distal intestinal obstruction (meconium ileus equivalent) • Pneumothorax or recurrent haemoptysis • Sterility in males
Pneumothorax
pneumothorax may occur spontaneously in up to 2% of deliveries. It is usually asymptomatic but may cause respiratory distress. Pneumothoraces also occur secondary to meconium aspiration, respiratory distress syndrome or as a complication of mechanical ventila- tion.
Bacterial tracheitis
This rare but dangerous condition is similar to severe epiglottitis in that the child has a high fever, appears very ill, and has rapidly progressive airways obstruction with copious thick airway secretions. It is typically caused by infection with Staphylococcus aureus. Man- agement is by intravenous antibiotics and intubation and ventilation if required.
