Paediatric Common Conditions 1 Flashcards
What is achondroplasia?
Achondroplasia is an autosomal dominant disorder associated with short stature
mutation in the fibroblast growth factor receptor 3 (FGFR-3) gene
This results in abnormal cartilage giving rise to:
short limbs (rhizomelia) with shortened fingers (brachydactyly)
large head with frontal bossing and narrow foramen magnum
midface hypoplasia with a flattened nasal bridge
‘trident’ hands
lumbar lordosis
What is acute epiglottitis? Presentation?
rare but serious infection caused by Haemophilus influenzae type B
Causes inflammation of the epiglottis
Features:
rapid onset
high temperature, generally unwell
stridor
drooling of saliva
‘tripod’ position
How can acute epiglottitis be diagnosed?
direct visualisation (only by senior/airway trained staff)
x-rays may be done, particularly if there is concern about a foreign body:
a lateral view in acute epiglottis will show swelling of the epiglottis - the ‘thumb sign’
PA view in croup will show subglottic narrowing, commonly called the ‘steeple sign’
How can acute epiglottitis be managed?
immediate senior involvement, including those able to provide emergency airway support (e.g. anaesthetics, ENT)
endotracheal intubation may be necessary to protect the airway
if suspected do NOT examine the throat due to the risk of acute airway obstruction
(the diagnosis is made by direct visualisation but this should only be done by senior staff who are able to intubate if necessary)
oxygen, IV antibiotics (ceftriaxone) , dexamethasone
What is the main complication to be aware of with epiglottitis?
epiglottic abscess, which is a collection of pus around the epiglottis
What is the most common malignancy affecting children?
Acute lymphoblastic leukaemia ( ALL)
How does ALL present?
anaemia: lethargy and pallor
neutropaenia: frequent or severe infections
thrombocytopenia: easy bruising, petechiae
Poor prognostic factors in ALL?
age < 2 years or > 10 years
WBC > 20 * 109/l at diagnosis
T or B cell surface markers
non-Caucasian
male sex
What are the key differentials for acute scrotal pain in children?
Testicular torsion - Most common around puberty
Irreducible inguinal hernia - Most common in children < 2 years old
Epididymitis - Rare in prepubescent children
Alpha-thalassaemia is due to a deficiency of alpha chains in haemoglobin.
Clinical severity depends on the number of alpha globulin alleles affected:
1/ 2 alpha globulin alleles affected = hypochromic and microcytic, Hb level is typically normal
3 alpha globulin alleles affected = hypochromic microcytic anaemia with splenomegaly, Hb H disease
If all 4 alpha globulin alleles are affected (i.e. homozygote) = death in utero (hydrops fetalis)
The Apgar score is used to assess the health of a newborn baby. At what times should it be used?
at 1, and 5 minutes of age
If the score is low then it is again repeated at 10 minutes
What are the APGAR criteria?
What are the normal values?
Activity (muscle tone)
Pulse
Grimace (reflex irritability)
Appearance (skin colour)
Respiratory effort
score of 0-3 is very low, between 4-6 is moderate low and between 7 - 10 means the baby is in a good state
How would you score activity (muscle tone) in the APGAR assessment?
active movement = 2
limb flexion = 1
flaccid = 0
How would you score pulse in the APGAR assessment?
> 100 = 2
< 100 = 1
absent = 0
How would you score grimace (reflex irritability) in the APGAR assessment?
Cries on stimulation/sneezes, coughs = 2
Grimace = 1
Nil = 0
How would you score appearance (skin colour) in the APGAR assessment?
pink = 2
body pink, extremities blue = 1
blue all over = 0
How would you score respiratory effort in the APGAR assessment?
strong, crying = 2

How should children with mild to moderate acute asthma be managed?
Bronchodilator therapy:
give a beta-2 agonist via a spacer (for a child < 3 years use a close-fitting mask)
give 1 puff every 30-60 seconds up to a maximum of 10 puffs
if symptoms are not controlled repeat and refer to hospital
Steroid therapy:
should be given to all children with an asthma exacerbation
treatment should be given for 3-5 days
What dose of prednisolone is given in kids with acute asthma?
1-2 mg/kg od (max 40mg)
OR
2 - 5 years = 20 mg od
> 5 years = 30 - 40 mg od
How should newly diagnosed asthma v newly diagnosed asthma with symptoms >= 3 / week or night-time waking be managed?
Newly diagnosed asthma = SABA
More symptomatic = SABA + paediatric low-dose inhaled corticosteroid (ICS)
What is the stepladder of mx for asthma in kids?
SABA
SABA + paediatric low-dose inhaled corticosteroid (ICS)
SABA + paediatric low-dose ICS + LTRA (e.g. montelukast)
SABA + paediatric low-dose ICS + LABA (e.g. Serevent- salmeterol)
In contrast to the adult guidance, NICE recommend stopping the LTRA at this point if it hasn’t helped
SABA + switch ICS/LABA for a maintenance and reliever therapy (MART)
What is Maintenance and reliever therapy (MART) ?
a form of combined ICS and LABA treatment in which a single inhaler, containing both ICS and a fast-acting LABA, is used for both daily maintenance therapy and the relief of symptoms as required
What is considered as a low dose ICS in kids?
<= 200 micrograms budesonide or equivalent
What is the stepladder for asthma mx in children under 5 years?
SABA
SABA + an 8-week trial of paediatric MODERATE-dose ICS
After 8-weeks stop the ICS and monitor the child’s symptoms:
if symptoms reoccur within 4 weeks of stopping ICS treatment, restart the ICS at a paediatric low dose as first-line maintenance therapy
if symptoms reoccur beyond 4 weeks after stopping ICS treatment, repeat the 8‑week trial of a paediatric moderate dose of ICS
SABA + paediatric low-dose ICS + LTRA
Referral for specialist assessment
What is ADHD?
Attention deficit hyperactivity disorder
a condition incorporating features relating to inattention and/or hyperactivity/impulsivity that are persistent
Give some features that might suggest “hyperactivity” ( ADHD criteria)
Unable to play quietly
Talks excessively
Does not wait their turn easily
Will spontaneously leave their seat when expected to sit
Is often ‘on the go’
Often interruptive or intrusive to others
Will answer prematurely, before a question has been finished
Will run and climb in situations where it is not appropriate
How can ADHD be managed?
ten-week ‘watch and wait’ period following presentation
Secondary care referral if sxs continue
Drug therapy should as a last resort and is only available to those aged 5 years +
Methylphenidate is first line and should initially be given on a 6 week trial basis
Dexamfetamine and Atomoxetine are also available
What is Methylphenidate’s mechanism of action? ADRs? How should patients be monitored?

What is autism?
a neurodevelopmental condition characterized by qualitative impairment in social interaction and communication as well as repetitive stereotyped behaviour, interests, and activities.
three to four times more common in boys than girls
typically evident before 2–3 years of age
What clinical features may autism present with?
Impaired social communication and interaction:
- Children frequently play alone and maybe relatively uninterested in being with other children
- may fail to regulate social interaction with nonverbal cues like eye gaze, facial expression, and gestures
- Fail to form and maintain appropriate relationships and become socially isolated
Repetitive behaviours, interests, and activities:
- Stereotyped and repetitive motor mannerisms, inflexible adherence to nonfunctional routines or rituals
- particular ways of going about everyday activities
ASD is often associated with intellectual impairment or language impairment
How can Autism spectrum disorder be managed?
Early educational and behavioural interventions
SSRIs: reduce symptoms like repetitive stereotyped behaviour, anxiety, and aggression
Antipsychotic drugs: reduce symptoms like aggression, self-injury
Methylphenidate: for associated ADHD
Family support and counselling
What is Benign rolandic epilepsy?
form of childhood epilepsy that typically occurs between the age of 4 and 12 years
Features:
seizures characteristically occur at night
seizures are typically partial (e.g. paraesthesia affecting the face) but secondary generalisation may occur (i.e. parents may only report tonic-clonic movements)
the child is otherwise normal
Excellent prognosis; seizures usually stop by adolescence
What is biliary atresia?
obliteration or discontinuity within the extrahepatic biliary system, which results in an obstruction in the flow of bile = neonatal cholestasis in first few weeks of life
What are the 3 types of biliary atresia?
Type 1: obliteration of the common bile duct
Type 2a : obliteration of the common hepatic duct
Type 2b: obliteration of the common bile duct, cystic duct, and hepatic duct
Type 3: obliteration of the common bile duct, cystic duct, and hepatic duct up to the level of the porta hepatis (90% of cases)

Jaundice extending beyond the physiological two weeks
Dark urine and pale stools
Appetite and growth disturbance, (however, may be normal in some cases)
Hepatomegaly with splenomegaly
Cardiac murmurs if associated cardiac abnormalities present
How should biliary atresia be investigated?
Serum bilirubin : Total bilirubin may be normal, whereas conjugated bilirubin is abnormally high
LFTs including serum bile acids and aminotransferases : usually raised but cannot differentiate causes of neonatal cholestasis
Serum alpha 1-antitrypsin: Deficiency may be a cause of neonatal cholestasis
Sweat chloride test: check for CF
Ultrasound of the biliary tree and liver: May show distension and tract abnormalities
How can biliary atresia be managed? Complications?
Surgical intervention is only definitive tx
Medical intervention includes antibiotic coverage and bile acid enhancers following surgery
Complications :
Unsuccessful anastomosis formation
Progressive liver disease
Cirrhosis with eventual hepatocellular carcinoma
What is Bronchiolitis? Offending pathogen? Presenting features?
acute bronchiolar inflammation
Usually RSV (respiratory syncytial virus)
other causes: mycoplasma, adenoviruses
may be secondary bacterial infection
coryzal symptoms (including mild fever) precede:
dry cough
increasing breathlessness
wheezing, fine inspiratory crackles
feeding difficulties
Give some signs of respiratory distress in a child
Raised respiratory rate
Use of accessory muscles of breathing, such as the sternocleidomastoid, abdominal and intercostal muscles
Intercostal and subcostal recessions
Nasal flaring
Head bobbing
Tracheal tugging
Cyanosis (due to low oxygen saturation)
Abnormal airway noises
Define wheezing, grunting and stridor
Wheezing is a whistling sound caused by narrowed airways, typically heard during expiration
Grunting is caused by exhaling with the glottis partially closed to increase positive end-expiratory pressure
Stridor is a high pitched inspiratory noise caused by obstruction of the upper airway, for example in croup
In which patients is bronchiolitis more likely to be severe?
bronchopulmonary dysplasia (e.g. Premature), congenital heart disease or cystic fibrosis
When should 999 be called for a child with bronchiolitis?
child looks seriously unwell to a healthcare professional
apnoea- cessation of respiratory effort lasting more than 20 seconds, or shorter accompanied with bradycardia or cyanosis
severe respiratory distress, for example grunting, marked chest recession, or a respiratory rate of over 70 breaths/minute
central cyanosis
persistent oxygen saturation of less than 92% when breathing air
How can bronchiolitis be investigated and managed?
immunofluorescence of nasopharyngeal secretions may show RSV
Management is largely supportive:
humidified oxygen is given via a head box
nasogastric feeding may be needed if children cannot take enough fluid/feed by mouth
suction is sometimes used for excessive upper airway secretions
What options are available for ventilatory support in children?
High-flow humidified oxygen via tight nasal cannula (“Airvo” or “Optiflow”):
delivers air and oxygen continuously with some added pressure (“positive end-expiratory pressure” (PEEP)) to maintain the airway at the end of expiration
Continuous positive airway pressure (CPAP):
involves using a sealed nasal cannula that can deliver much higher and more controlled pressures
Intubation and ventilation
What is palivizumab?
a monoclonal antibody that targets the respiratory syncytial virus
A monthly injection is given as prevention against bronchiolitis caused by RSV to high risk babies, such as ex-premature and those with congenital heart disease.
What is bronchopulmonary dysplasia?
also known as Chronic lung disease of prematurity (CLDP)
It occurs in premature babies, typically before 28 weeks gestation, who suffer with respiratory distress syndrome and require oxygen therapy or intubation and ventilation at birth
Diagnosis is made based on chest xray changes and when the infant requires oxygen therapy after they reach 36 weeks gestational age.
How can bronchopulmonary dysplasia (or CLDP) be prevented?
Giving corticosteroids (e.g. betamethasone) to mothers that show signs of premature labour at less than 36 weeks gestation
Once the neonate is born the risk of CLDP can be reduced by:
Using CPAP rather than intubation and ventilation when possible
Using caffeine to stimulate the respiratory effort
Not over-oxygenating with supplementary oxygen
How can bronchopulmonary dysplasia (or CLDP) be managed?
formal sleep study to assess their oxygen saturations during sleep
Babies may be discharged from the neonatal unit on a low dose of oxygen to continue at home, via nasal cannula. They are followed up to wean the oxygen level over the first year of life.
Babies with CLDP require protection against respiratory syncytial virus (RSV) - monthly injections of a monoclonal antibody (palivizumab)
Differntiate between Caput succedaneum and Cephalohaematoma
Both are swellings on the head of a newborn, more common following prolonged/ difficult deliveries
Managed conservatively

Resolves within days
Cephalohaematoma: collection of blood between periosteum and skull
Typically develops several hours after birth
Most commonly in parietal region, doesn’t cross suture lines
May take months to resolve

Possible manifestations include:
abnormal tone in early infancy
hand preference below 18 months
delayed motor milestones
abnormal gait
feeding difficulties
learning difficulties
Describe the gait that may be seen in cerebral palsy
hemiplegic or diplegic gait
this gait is caused by increased muscle tone and spasticity in the legs
the leg will be extended with plantar flexion of the feet and toes, meaning they have to swing the leg around in a large semicircle when moving their leg from behind them
What may you see on examination of a patient with cerebral palsy?
signs of an upper motor neurone lesion
good muscle bulk, increased tone, brisk reflexes and slightly reduced power
look for athetoid movements that indicate extrapyramidal (basal ganglia) involvement
What can cause cerebral palsy?
antenatal (80%): e.g. cerebral malformation and congenital infection (rubella, toxoplasmosis, CMV)
intrapartum (10%): birth asphyxia/trauma
postnatal (10%): intraventricular haemorrhage, meningitis, head-trauma
What are the different classifications of cerebral palsy?
spastic (70%)
hemiplegia, diplegia or quadriplegia
increased tone resulting from damage to upper motor neurons
dyskinetic
damage to the basal ganglia and the substantia nigra
athetoid movements and oro-motor problems
ataxic
caused by damage to the cerebellum with typical cerebellar signs
mixed

anticonvulsants, analgesia as required.
Chickenpox is caused by primary infection with varicella zoster virus. How does it present?
fever initially
itchy rash starting on head/trunk before spreading - macular then papular then vesicular
systemic upset is usually mild
infectivity = 4 days before rash, until 5 days after the rash first appeared
How can chickenpox be managed?
keep cool, trim nails
calamine lotion
school exclusion: until lesions have crusted over (usually about 5 days after the onset of the rash)
immunocompromised patients and newborns with peripartum exposure should receive varicella zoster immunoglobulin (VZIG)
If chickenpox develops then IV aciclovir should be considered
Complications of chickenpox?
Secondary bacterial infection of the lesions - NSAIDs may increase risk, group A strep may cause necrotising fasciitis

cleft lip results from failure of the fronto-nasal and maxillary processes to fuse
cleft palate results from failure of the palatine processes and the nasal septum to fuse
How can feeding and speech be improved in children with cleft lip / palate?
What problems can cleft palate cause?
feeding: orthodontic devices may be helpful
speech: with speech therapy 75% of children develop normal speech
increased risk of otitis media for cleft palate babies
How are cleft lip and palate managed?
cleft lip is repaired earlier than cleft palate, with practices varying from repair in the first week of life to three months
cleft palates are typically repaired between 6-12 months of age

Can add a stimulant laxative after 2 weeks if needed
consider regular toileting and non-punitive behavioural interventions
consider asking the Health Visitor or Paediatric Continence Advisor to help support the parents
How can constipation in an infant be managed?
Infants not yet weaned (usually < 6 months)
bottle-fed infants: give extra water in between feeds. Try gentle abdominal massage and bicycling the infant’s legs
breast-fed infants: constipation is unusual and organic causes should be considered

Central cyanosis in the neonatal period can be recognised clinically when the concentration of reduced haemoglobin in the blood exceeds 5g/dl. How can you distinguish between cardiac and non-cardiac causes?
The nitrogen washout test
The infant is given 100% oxygen for ten minutes after which arterial blood gases are taken. A pO2 of less than 15 kPa indicates cyanotic congenital heart disease
Initial management of suspected cyanotic congenital heart disease?
supportive care
