(42 cards)
1
Q
What is rhinitis?
A
- URTI
- Very common
□ 5-10 per year - Winter months
- Self-limiting condition
- Prodrome to other illnesses
□ Pneumonia, bronchiolitis
□ Meningitis
□ Septicaemia - Review if not sure
- Typically lasts 11 days before they resolve but they may be a little longer
2
Q
What is otitis media?
A
- URTI
- Pain and redness
- The drum is no longer red and shiny
- The drum is being pushed forward until it bursts and then it gets better
- On average lasts 3 days- 1 week
- Primary viral infection
- Secondary infection with pneumococcus/ H’flu
- Spontaneous rupture of the drum
3
Q
What is the treatment of otisis media?
A
- Antibiotic treatment usually doesn’t help
- Oxidation, hydration, analgesia and nutrition
- Analgesia
4
Q
What is tonsillitis/ pharygitis and how is it diagnosed?
A
- URTI
- Common
- Viral or bacterial
- Throat swab
5
Q
What is the treatment for tonsillitis/ pharyngitis?
A
- Either nothing or 10 days penicillin
□ Ongoing swinging fevers and rash give penicillin as it suggest bacterial- you can’t tell from the throat - Don’t give amoxycillin
6
Q
What is Croup?
A
- URTI
- Para’ flu I
- Common

- Loose rattily cough
- Post-tussive vomit- “glut”
- Chest free of wheeze/ creps
- Haemophilus/ pneumococcus
- Mostly self-limiting
- Child very well, parent worried
- Symptoms have been going on for the whole winter
12
Q
What is the mechanisms that cause bronchitis?
A
- Disturbed mucociliary clearance ◊ Minor airway malacia ◊ RV/ adenovirus - Lack of social inhibition - Bacterial overgrowth is secondary
13

A
□ Make the diagnosis
□ Reassure
□ Do not treat
14

- Static weight
- Disrupts child’s life
- Associated SOB (when not coughing)
- Acute admission
- Other co-morbidities (neuro/ gastro)
15
Q
What is bronchiolitis?
A
- LRTI
- A clinical diagnosis
- LRTI of infants
- Affect 30-40% of all infants
- Usually RSV, others include paraflu III, HMPV (human metapneuma virus)
- Nasal stuffiness, tachypnoea, poor feeding
- Crackles +/- wheeze
- There is no uncertainty
□ <12 months old
□ One off (not recurrent)
□ Typical history…
16
Q
What investigations are carried out in bronchiolitis?
A
□ NPA (nursing in same ward) □ Oxygen saturations (severity) □ No routine need for ® CXR ® Bloods ® Bacterial cultures
17
Q
What is the management of bronchiolitis?
A
□ Make sure oxygen, hydration and nutrition is ok
□ Maximal observation
□ Minimal intervention
18
Q
How can you tell if it is pneumonia?
A
- Totally academic
- Word causes great anxiety
- You might call it pneumonia if
□ Signs are focal, i.e. in one area
□ Creps
□ High fever - Otherwise call it LRTI
19
Q
What investigations are done for comunity aquired pneumonia?
A
CXR and inflammatory markers not routine
20
Q
What is the management of community aquired pneumonia?
A
® Nothing if symptoms are mild ® Always review if things are getting worse ® Oral Amoxycillin first line ® Oral Macrolide second line ® Only for IV if vomiting
21
Q
What is Pertusis?
A
- Whooping cough
- Common
- Vaccination reduced risk
- Vaccination reduces severity
- “coughing fits”
- Vomiting and colour change
22
Q
Do you give antibiotics to a child with otitis media?
A
No unless age under two years AND bliateral OM give oral amaxycillin
23
Q
Do you give antibiotics to a child with Bronchiolitis?
A
No
24
Q
Do you give antibiotics to a child with Tonsillitis?
A
Yes (if you know it is strep.) give penicillin
25
Do you give antibiotics to a child with LRTI/ pneumonia?
No, unless 2 day history of fevere, cough and focal signs then give oral amoxycillin
26
Do you give antibiotics to a child with Bronchitis?
No
27
What is asthma?
- Chronic
- Wheeze, cough, SOB
- Variable/ reversable
- Responds to asthma treatment
- No uniform definition
28
What are the triggers of asthma
- URTI
- Exrercise
- Allergen
- Cold weather
- ETC.
29
What is the aetiology of asthma?
```
- Genes
□ ~10 variants making modest contribution
□ ADAM33, ORMDL3
- Interact with the environment
□ Rhinovirus
□ Exercise
□ Smoking
- Epigenetics
```
30
How is asthma diagnosed in children?
- All in the history
- Examination unhelpful
□ Unlikely to be wheezing
□ Stethoscope never important (often unhelpful)
- No asthma test in children
□ Peak flow random number generator
□ Allergy test irrelevant
□ Spirometry lacks specificity
□ Exhaled nitric oxide unproven
31
How is one able to tell if a child has asthma?
```
- Wheeze
□ A must have
□ Cough variant asthma does not exist
□ Cough predominant asthma not uncommon
- SOB at rest
□ Lost 70% lung function
□ Using their abdomen to breath
- Cough
□ Everyone coughs
□ Dry
□ Nocturnal (just after falling asleep)
□ Exertional
- Responds to treatment
□ What has asthma symptoms and responds to asthma treatment?
□ Asthma treatment= ICS for 2 months
□ Remember "false positive responses"- holiday
```
32
What is the differential diagnosis for asthma if the onset is under 5 years?
```
□ Congenital
□ CF
□ Primary ciliary dyskinesia
□ Bronchitis
□ Foreign body
```
33
What is the differential diagnosis for asthma if the onset is over 5 years?
□ Dysfunctional breathing
□ Vocal cord dysfunction
□ Habitual cough
□ Pertussis
34
What are the goals of treatment in asthma?
□ "Minimal" symptoms during day and night
□ Minimal need for reliever medication
□ No attacks (exacerbations)
□ No limitation of physical activity
35
How is asthma monitored?
® Closed questions
® SANE
◊ Short acting beta agonist/ week (>2 days a week then asthma is poorly controlled)
◊ Absence school/ nursery
◊ Nocturnal symptoms (if you get it once a week)
◊ Exertional symptoms/ week
36
What are the classes of asthma medication?
```
® Short acting beta agonists
® Inhaled corticosteroids
® Long acting beta agonists*
® Leukotriene receptor antagonists*
® Theophylline
® Oral steroids
® *=add ons
```
37
Explain inhaled corticosteroids
```
◊ Very useful for diagnosis
◊ Very effective
◊ Very safe (when prescribed correctly)
◊ Adverse effects
- Hight suppression (0.5-1cm)
- Oral canditis
- Adrenocortical suppression
- Doesn't cause hypertension
- Doesn't cause cataracts
```
38
When should you use a regular preventer in asthma?
◊ Diagnostic test
◊ B2 agonist >2 days a week
◊ Symptomatic three times a week or more, or waking one night a week
39
What should be used as a regular preventer in asthma>
Start with low dose inhaled corticosteroids (or LTRA in <5s)
40
What non-medication interventions should be done in asthma?
```
□ Stop tobacco smoke exposure
□ Remove environmental triggers
® Cat, Dog
® HM??
□ Diet- evidence negative
□ Alter humidity- no evidence
® Air ionisers increase cough
□ Weight reduction- no evidence
```
41
What is the step-up step-down approach to treating asthma in children?
□ Start on low dose ICS
® Severe may respond to minimal treatment
□ Review after 2 months
® No routine test to monitor progress
® Stepping up easier than down
® Need an inhaler holiday when Easter comes round
42
What is the initial add on preventer?
```
□ Gets complicated
® Add on LABA or LTRA (BTS/SIGN)
® Add on LTRA (NICE)
® Increase ICS dose (GINA)
® Add on LABA but keep an open mind (clinician)
□ Long acting beta agonist***
® Do not use without ICS
® Use as fixed dose inhaler
□ Leukotriene receptor agonist
® Montelukast only
® Rule of thirds
® Better adherence
® Granules for reluctant toddlers
```
