Caused by Haemophilia influenza type b (HIb)

18
Q

A

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

19
Q

20
Q

Pertussis clinical features

A
Week of coryza 
Paroxysmal or spasmodic cough
Inspiratory whoop
Often worse at night may have cough
Goes red/blue in the face
21
Q

Cystic fibrosis

A

Autosomal recessive disease

Misfolded CFTR

22
Q

Clinical features of CF

A

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
23
Q

Pneumothorax

A

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.

24
Q

Bacterial tracheitis

A

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.

25
Laryngomalacia
Most common cause of stridor in infancy. Due to congenital softening of the tissues of the larynx. Hence predisposed to collapse upon inspiration and partially block airway.
26
Clinical features of bronchiolitis
``` dry wheezy cough • tachypnoea and tachycardia • subcostal and intercostal recession • hyperinflation of the chest • fine end-inspiratory crackles • high-pitched wheezes – expiratory > inspiratory. ```
27
Laryngomalacia presentation
Feeding related vomiting choking etc Fine inspiratory crackles Weight loss and failure to thrive presents at birth or within 6 weeks peaks at 6-8 months. Often Dx at 4.
28
Bronchiolitis Tx
Humidified air | May require fluids or CPAP
29
Causes of anaphylaxis
``` Food allergy Drugs Insect stings Latex Exercise ```
30
signs of anaphylaxis AABC skin
``` Acute Onset Airway: swelling hoarsness, stridor Breathing: Tachypnoea, wheeze, Sp02>92% Circulation: Clammy, Pale, hypotension, drowsy, coma Skin: Urticaria, angiodema ```
31
Emergency treatment of anaphylactic shock
ABCDE If breathing difficult Sit up If hypotensive- supine and elevate legs If unconcious- recovery position and BALS. ``` Adrenaline- 1:1000 IM Additional treatment: Establish airway High-flow oxygen IV fluid (20 ml/kg crystalloids) Chlorpheniramine (IM or slow IV) Hydrocortisone (IM or slow IV) Consider salbutamol if wheeze ```
32
CENTOR criteria
Tonsillar exudate Tender anterior cervical lymphadenopathy or lymphadenitis History of fever (over 38°C) Absence of cough
33
What Centor score require Abx
3/4
34
Tx for tonsillitis/pharyngitis who require Abx
Phenoxymethylpenicillin 1 to 11 months, 62.5 mg four times a day or 125 mg twice a day for 5 to 10 days 1 to 5 years, 125 mg four times a day or 250 mg twice a day for 5 to 10 days 6 to 11 years, 250 mg four times a day or 500 mg twice a day for 5 to 10 days
35
Acute otitis media presentation
Most common 6-12 months Fever Bright red bulging with loss of light reflection May have perforation or pus visible
36
Tx for acute otitis media
Paracetamol or ibuprofen for the pain | Can give prescription of amoxicillin and tell parents to only give if child unwell after 2-3 days
37
Tx of otitis media with effusion
Grommets | If persists grommet insertion with adenoidectomy
38
Allergic rhinitis Tx
Second-generation non-sedating antihistamines (used topically or systemically) • Topical corticosteroid nasal or eye preparations (the latter under specialist ophthalmology supervision) • Cromoglycate eye drops • Leukotriene receptor antagonists, e.g. montelukast • Nasal decongestants (use for no more than 7–10 days due to risk of rebound effect) • Allergen immunotherapy – sublingual or subcutaneous (limited by anaphylaxis risk) • Systemic corticosteroids should not be used due to the risk of adverse effects
39
Acute sinusitis
Often paranasal sinus as frontal sinuses do not develop until late childhood. Treat with Abx and analgaesia. Ofte secondary to URTI
40
Tx for epistaxis
Lean forward, pinch nose cartilage firmly for 10-15mins. If still bleeding: Nasal cautery Nasal Packaging If bleeding is posterior aspect of nose admit to hospital
