Q

What is the utility of blood cultures in PUO?

A

Poor positive predictive value (contamination > actual infection) and poor negative predictive value (small volumes usually >1ml)
However younger children have higher rates of OB and SBI so it is recommended

Q

Why is Aspirin avoided in children?

A

The risk of Reye’s Syndrome, a rapidly progressive encephalopathy with hepatic dysfunction
Largely occurs when given to children infected with VZV or Influenza A + B

Q

When is NG fluid resuscitation deemed appropriate?

A

In Pre-school aged children not accepting oral rehydration and only mild to moderately dehydrated (10% or less dehydrated)

Caution in dehydration caused by conditions prone to SIADH (meningoencephalitis, resp infections) or known electrolyte disturbance

Q

How is NG bolus dosing of fluids done? What is put down the NG?

A

10-25ml/kg/hr over 4 hrs
so 10kg child would get 100-250mls/hr for 4 hrs with a total of 400-1000mls
Rates generally do not exceed 300mls/hr, if wanting to give more fluids then do so over longer time ie 6hrs

Pedialyte (or breast mild depending on age)

Q

What are the advantages of NG fluids over IV fluids

A

Safer due to less risk of electrolyte derangment
Usually well tolerated
Help promote recovery from Gastroenteritis
Have the option to given nutritional fluids (ie breast milk)

17
Q

For maintenance fluids what is the NGT rate?

A

Same as IV fluids, 4mls/kg for 1st 10kg, 2mls/kg for the next 10kg, 1ml/kg every kg after this
If CNS or Resp infection the the total dose and rate should 2/3rds the amount due to risk of SIADH

18
Q

What are the Can NOt MISS diagnoses, the 7 for patients under 7?

A

Cardiac
NAI
Oncological/Tumour
Metabolic
Ingestions + FB
Surgical
Sepsis

19
Q

What are the differences in the airways of infants and small children?

A

Obligate nasal breathers
larger tongues
larynx more anterior and cranial
cricoid is the narrowest part of the airway (as opposed to the vocal folds in adults)

20
Q

What are the redlfags for children with airway noises?

A
  • Severe croup during the day
  • <12 months old
  • Known structural abnormalities (ie laryngomalacia)
  • Un-immunised
  • Already treated but still severe (ie adrenaline and dexamethasone)
  • Cerebrally agitated
  • Signs of tiring
21
Q

What is a mnemonic for NAI in children?

A

TEN 4 FACESp

Trunk
Ears
Neck

Frenulum
Angle of Jaw
Cheeks
Eyelids
Subconjunctiva
patterned injuries

Above are for children under 4 years

Any bruising in child <4months should be suspicious for NAI

22
Q

Differential other than NAI for unusual bruising?

A

Coagulopathy
Malignancy
DIC
Vit K deficiency
Mongolian blue spot
ITP
sepsis with purpura

23
Q

Burns red flags

A

<5yo
Higher TBSA
bilateral
Scalds (non-spill injury pattern)
- Immersion pattern
- thrown spill pattern
Hot water (neglect)
Posterior trunk, genitals, buttocks and legs other than the feet

24
Q

Fracture red flags

A

Any in pre-mobile child
long bone injury <3yo
Bucket handle/metaphyseal edge
Posterior ribs
scapular/sternal/spinal
Hands and feet
Multiple, old or healing
Complex or multiple skull fracture

25
Q

Differentials for severe anaemia in children?

A
  • GI bleed
  • Trauma
  • Blood cancer
  • Diet (cows mild protein allergy, iron poor diet leading to deficiency etc)
  • Haemolysis (G6PD deficiency, sickle cell anaemia, HUS, drug induced, sepsis etc)
  • Vitamin K deficiency in neonates
  • Transient erythblastopaenia of childhood
26
Q

What are the common things that should be avoided in G6PD deficiency?

A

Fava beans (Favism)
Any infections
Sulfamethoxazole
Dapsone
Rasburicase
Amyl nitrate (sexually active)

27
Q

What are the specific differentials for limp in a toddlers 0-4?

A

Transient hip synovitis (most common)
Toddlers fracture (most specific to age)

Other
Acute Myositis
Developmental dysplasia of the hip

28
Q

Why are Down syndrome children at higher risk of respiratory presentations and deterioration?

A

Development delay
- Late presentation
Hypotonia + GORD
- Risk of aspiration
Heart defects
- higher risk cardiac failure
OSA and pulmonary HTN
Relatively immunocompromised
High risk of AML
- Atypical infections

29
Q

What is the most accurate weight for age calculation?

A

(3x age) +7
So a 5yo would be 15 + 7 = 22kg

APLS uses (age +4) x 2
So a 5yo would be 18kg

Both can be used, but 3xage +7 is considered more accurate in developed countries as it has been shown to underestimate “well nourished” children less (33% vs 6% underestimation_

30
Q

What are the general criteria for discharge to be met for the safe discharge of a child for any general medical problem?

A
  • Significant acute medical issues excluded
  • Responsible adult to care for child
  • Safe transport home (ie drunk parent cant drive them home)
  • Return advice given for the medical presentation
  • Discharge information and follow up as applicable
  • Time of day (generally not overnight)
  • Risk assessment performed ie home situation, NAI etc
31
Q

What are the risk factors for SIDS?

A

Maternal
- Young maternal age (<20)
- Smoking during pregnancy
- Late or no pre-natal care

Infant
- Low birth weight
- Pre-term deilvery
- Sibling had SIDS (x5 risk)

Environment
- Prone sleeping position
- Bed sharing
- Overheating
- Loose accessories (blankets, pillows)
- Sleeping on a soft surface

32
Q

What are the preventative measures for SIDS?

A
  • Smoking cessation
  • Pre-natal care
  • Supine sleeping
  • Firm sleep surface
  • Room sharing without bed sharing
  • Pacifier use
  • Prevent overheating
  • No loose objects in bed
33
Q

If you are suspecting NAI how generally should this be approached?

A
34
Q

What is the definition and crtieria for diagnosis of a BRUE? What investigations are performed for non-low risk BRUE’s? How are BRUE’s risk stratified?

A

Investigations
- BSL
- ECG
- Urine
- Basic bloods +/- culture
- NPA for viruses + Pertussis
- FBE and UEC

Low risk
- No concerning features oh Hx/Exam
- Age >60 days
- Born >32 weeks and currently >45 weeks corrected age
- No trained healthcare professional CPR
- 1st event
- Lasted <1minute

35
Q

When considering diagnosing rheumatic fever in indigenous patients, what is a general differential list?

A
  • RA or JRA
  • Kawasakis disease
  • SLE
  • Sepsis/septic arthritis
  • Reactive/Gonococcal arthritis
  • Influenza/covid
  • EM Major/SJS/TEN
36
Q

What factors form part of the general follow up for Rheumatic fever?

A
  • Patient has access to and is educated on monthly IM injections
  • Patient has been educated on and has the times for their cardiology/echo follow up
  • Patients is readily contactable ie have their phone number, address or some other reliable way to contact
37
Q

What is thought to be the most common cause of BRUE’s?

A

Exaggerated airway reflexes in the context of feeding, reflux or increased upper airway secretions
