Paeds Key Flashcards
Acute epiglottitis
◘ A rare but serious infection
◘ Caused by Haemophilus influenzae type B.
◘ Immediate recognition and treatment is essential as airway obstruction may
develop.
◘ Epiglottitis was generally considered a disease of childhood but in the UK, it
is now more common in adults due to the immunisation programme.
Causative organism of acute epiglottis
is haemophilus influenzae type B
Features of acute epiglottis
And management
The incidence of epiglottitis has decreased since the introduction of the Hib
vaccine. (Hib = Hemophilus Influenza type B).
Features
√ rapid onset
√ high temperature,
√ generally unwell, toxic child
√ stridor
√ drooling of saliva
√ Muffling/ hoarse / Changing voice.
√ lateral neck X-ray → Thumb sign
◙ Rx
◙ Call (Summon) anaesthetist → Intubation “before airway obstruction occurs”
◙ Secure His Airways
Any of these two would be a valid answer in Acute epiglottitis
Croup (Laryngotracheobronchitis)
◙ An upper respiratory tract infection seen in infants and toddlers.
◙ Commonest organism → Parainfluenza viruses.
◙ Features
√ stridor
√ barking cough (worse at night) “often the hint”
√ fever
√ coryzal symptoms
√ X-ray → Steeple sign.
Severe croup symptoms
◙ If moderate to severe, we admit. Look at these features of severe croup:
♠ Frequent barking cough.
♠ Prominent inspiratory (and occasionally, expiratory) stridor at rest
.
♠ Marked sternal wall retractions.
♠ Significant distress and agitation, or lethargy or restlessness (a sign of
hypoxaemia).
♠ Tachycardia occurs with more severe obstructive symptoms and
hypoxaemia.
◙ Management of Croup (important √)
√ A single dose of oral dexamethasone 0.15mg/kg to all children regardless of severity.
(Prednisolone is an alternative if dexamethasone is not available).
◙ Emergency treatment
high-flow O2
Nebulised adrenaline → In severe cases of croup.
√ The prognosis of most cases of barking cough (Croup) is:
→ natural resolution (complete recovery).
Nocturnal Enuresis.
♦ The majority of children achieve day and night time continence by 3 or 4 YO.
♦ Enuresis → ‘involuntary discharge of urine by day or night or both, in a child ≥ 5
YO, in the absence of congenital or acquired defects of the nervous system or
urinary tract’
.
♦ Nocturnal enuresis can either be
:
Primary- the child has never achieved sustained continence before)
or,
secondary
(the child had been dry for at least 6 months before).
Management of Primary Enuresis
(The child has never achieved sustained continence before)
Management of Primary Enuresis
(The child has never achieved sustained continence before)
◙ If WITH Daytime enuresis (+) > 2 YO
→ Refer to 2ry care or enuresis clinic for further assessment.
This is the case here but he is already being seen in the 2ry care.
Important Causes (imp. √):
√ Urinary tract infections (need urine dipstick, urinalysis, possibly urine culture and
√ Urge incontinence (Overactive bladder):
Bladder retraining.
antibiotics).
- This is treated by →
- Another valid answer is →
1.- If Bladder retraining and or 2.Behavioural therapy are not given in the options or
tried but failed, go for → Oxybutynin or drugs (anticholinergics).
Behavioural Therapy.
Tolterodine, which are antimuscarinic
√ Others: congenital malformations, chronic constipation, neurological disorders.
◙ If WITHOUT Daytime symptoms (only night bedwetting)
• < 5 YO → Reassure (they may achieve continence soon).
• ≥ 5 YO:
◘ If infrequent (<2 times a week) → Reassure.
◘ If frequent (>2 times a week):
💕If Long-term control is required → (enuresis alarm)(
💕first-line)
Reward system
+ -
💕If short-term control of bedwetting is required (eg, the child is going to sleep at a
camp for 2 days) or > 7 YO → (
ie, for
💕temporary control and is also useful in overactive bladder ie urge incontinence).
Desmopressin -orally not intranasally- for temporary control
💕If after 2 complete courses of treatment with alarm, reward system, desmopressin,
they are still bedwetting → Refer to 2ry care.
Management of 2ry Enuresis.
The child was dry for at least 6 months of his life and then started wetting
himself at night ± at daytime
→ Refer to a Paediatrician
√ Common causes of 2ry enuresis → Emotional upset (could be a result of child
abuse),
UTI, DM (polyuria), constipation. Therefore, a paediatrician needs to
investigate possible causes.
General Points
√ Look for possible underlying causes/triggers (e.g. Constipation, diabetes mellitus,
UTI if recent onset, emotional upset).
√ Advise on fluid intake, diet and toileting behaviour.
√ Reward systems (eg, Star charts). NICE recommend these ‘should be given for
agreed behaviour rather than dry nights’ e.g. Using the toilet to pass urine before
sleep, give reward.
√ NICE advise: ‘Consider whether alarm or drug treatment is appropriate,
depending on the age, maturity and abilities of the child or young person, the
frequency of bedwetting and the motivation and needs of the family’ (Ass shown
above).
√ Generally:
◘ An enuresis alarm is first-line for children under the age of 7 years.
◘ desmopressin may be used first-line for children over the ago 7 years,
particularly
if short-term control is
needed or an enuresis alarm has been
ineffective/is not acceptable to the family.
Reflux Nephropathy
• Urine goes back from bladder to ureters and kidneys (Vesico-Ureteric Reflux)
→ Dilated Pelvicalyceal system → Repeated UTIs → Progressive Renal Failure.
• Occurs mainly in the young (children).
♦ An important cause → Congenital abnormality of the insertion of ureters
into the urinary bladder (can be seen on US).
Reflux Nephropathy
• Urine goes back from bladder to ureters and kidneys (Vesico-Ureteric Reflux)
→ Dilated Pelvicalyceal system → Repeated UTIs → Progressive Renal Failure.
• Occurs mainly in the young (children).
♦ An important cause → Congenital abnormality of the insertion of ureters
into the urinary bladder (can be seen on US).
Dx
√Initial
√Gold standard
√For parenchymal damage →
1.Renal Ultrasound (+) Urinalysis, urine culture and sensitivity.
2.→ Micturating Cystourethrogram. (Not done >3 years age).
(3. cortical scars) → Technetium Scan (DMSA).
Reflux Nephropathy
• Urine goes back from bladder to ureters and kidneys (Vesico-Ureteric Reflux)
→ Dilated Pelvicalyceal system → Repeated UTIs → Progressive Renal Failure.
• Occurs mainly in the young (children).
♦ An important cause → Congenital abnormality of the insertion of ureters
into the urinary bladder (can be seen on US)
For Exam: Recurrent UTIs in children:
• First-step → US.
• Next step→ DMSA. (Not urgent, can be booked 4-6 month after acute UTI).
♦ Rx
√ Initially → Low-dose antibiotics prophylaxis (trimethoprim) daily.
√ Failed? Or Parenchymal damage? → Surgery (Ureters Re-implantation).
◙ Branchial cyst → Lateral neck mass – Not-translucent.
◙ Lymphangioma → Lateral neck mass – Translucent.
Lateral = along or near sternocleidomastoid muscle.
◙ Painless, mobile lump in the anterior midline neck that moves up with
tongue protrusion ➔ Thyroglossal Cyst.
√ The most appropriate Ix → Ultrasound!
If suspicious → FNAC
Notes:
* Thyroglossal cyst is the commonest neck congenital anomaly.
* It may become painful if infected.
- A thyroglossal cyst moves up with tongue protrusion because it is
attached to the thyroglossal tract which attaches to the larynx by the
peritracheal fascia. - A neck midline lump that moves up with swallowing → Goitre?
- Fluctuant lump and transilluminate in the neck → Cystic hygroma?
Suspect Non-Accidental Injury (Child Abuse) in Paediatrics if:
◙ Delayed presentation to medical care.
◙ Delay in attaining milestones (eg, low weight for age).
◙ Lack of concordance between proposed and actual mechanism of injury
(the carer gives a Hx which is not compatible with the signs and injuries
).
◙ Multiple injuries.
◙ Injuries/ Bruises at sites not commonly exposed to trauma.
◙ Bruises are often of varying degrees and colours.
◙ A child/ baby lives with a step-parent or a friend
◙ Irritable, crying, distressed baby with multiple bruises (in pain).
◙ The victim child is Not making eye contact.
Management
Admit to ward
→ relieve pain and treat underlying medical conditions
→ perform Skeletal Survey (Then)
→ inform local safeguarding
→ refer to social service
◙ Note that the answer can be a mix of two of the above.
For example, → Admit to general paediatrics ward + Refer to social service.
Skeletal Survey ◙ Also note that after giving analgesia, perform seek legal child protection (inform safeguarding, refer to social services).
and THEN
Note, do not get distracted by a “runny nose” in a baby with low weight for
age,
multiple bruises and irritability.
Runny nose might just be a result of
excessive crying 2ry to pain and abuse.
Other Distractors (DDx)
Bruises: (See haematology chapter)
• Haemophilia (X-linked recessive, so the affected individual is a boy mainly)
→ ↑ PTT + (Bleeding into muscles or joints or easily bleeds).
• Henoch-Schonlein Purpura (HSP)
HSP → PAAN: non-blanching Purpura ± Arthralgia, Abdominal pain,
Nephropathy (Hematuria, Proteinuria).
• Purpura is non-blanching and mainly on the buttocks and Lower Limbs.
• Precipitated by URTI – Sore Throat.
• All Blood Results are NORMAL “Normal Hb, WBCs and Platelets”.
• However, there might be ↑ ESR/ IgA/ Creatinine.
• One rare complication of HSP is → Intussusception (severe abdominal pain +
rectal bleeding in 6-36 months old. It can develop a few days after HSP)
• Idiopathic Thrombocytopenic Purpura (ITP)
Isolated Thrombocytopenia (low platelets) has to be given in a stem.
Fractures
• Osteogenesis Imperfecta
(Type 1- Autosomal dominant – collagen metabolism disorder → Brittle Bone Disease)
Other hints would be given, which are:
Blue Sclera ▐ Dental abnormalities ▐ Brittle bones - ▐ Multiple/
Unexplained fractures ▐ Hearing loss 2ry to Otosclerosis
→ Give Bisphosphonate
Management of Acute Asthma Exacerbation in Paediatrics
1 ♦ O2
2 ♦ Salbutamol 3 ♦ Add Nebuliser (could be given back-to-back).
Nebuliser.
“Salbutamol and Ipratropium can be mixed in a solution and repeated)
Ipratropium Bromide 4
♦ Corticosteroids
√ Oral prednisolone (either liquid or crushed tablets dissolved in water)
√ OR IV hydrocortisone.
5 ♦ If still in asthma exacerbation, consider:
♠ IV Magnesium sulphate (MgSO4): tried first before the following 2 options.
♠ IV Salbutamol
♠ IV Aminophylline (unlikely to be the correct answer as it is given by seniors
in severe life-threatening asthma exacerbations that have failed to respond to
the max doses of bronchodilators and steroids)
◙ Once there is a Silent chest → Intubate.
Salbutamol is a short-acting beta2 agonist (SABA)
Ipratropium bromide is anticholinergic.
After giving O2, Salbutamol…etc, if the child develops tachypnea, SOP, drowsiness
Request → Arterial blood gas.
(To look for respiratory acidosis and manage accordingly)
DDx of Stridor in paediatrics:
Acute epiglottitis and Croup are mentioned above.
Inhaled FB ♦ Symptoms depend on the site of impaction of foreign
body.
♦ Features are of sudden onset.
→ coughing, choking, vomiting, stridor.
→ Laryngoscopy
Laryngomalacia ♦ Congenital abnormality of the Larynx. √
♦ Typically presents at 4 weeks of age with → Stridor.
♦ Stridor can be worse on crying.
♦ Usually resolve within one year of life.
♦ Laryngomalacia is the most common congenital
airway disorder and the most common cause of stridor
in neonates.
Asked before:
What structure is not fully developed at birth?
→ Larynx.
• Hx of travel, WATERY Diarrhea (Not-bloody), Weight Loss,
abdominal pain, foul-smelling flatulence, bloating → Giardiasis
♦ First line Investigation → ♦ Another investigation → Stool ELISA/ PCR
Stool microscopy “for ova and parasite
♦ First line Rx → Metronidazole + Hygiene.
