Unexplained rash or bruising — may indicate haematological or inflammatory joint disease, or child maltreatment.
Limp and stiffness worse in the morning — may indicate inflammatory joint disease.
Unable to bear weight or painful limitation of range of motion — may indicate trauma or infection.
Severe pain, anxiety, and agitation after a traumatic injury — may indicate neurovascular compromise or impending compartment syndrome.

projectile vomiting
examination findings in pyloric stenosis?>
f examined after feeding, often the peristalsis can be seen by observing the abdomen. A firm, round mass can be felt in the upper abdomen that “feels like a large olive”. This is caused by thehypertrophicmuscle of thepylorus.
PS ABG?

Urinary frequency
Signs and symptoms in of UTIs older infants and children are more specific:

patches of reduced uptake -> scarring
VUR?
> Vesico-ureteric reflux (VUR) is where urine has a tendency to flow from the bladder back into the ureters.
This predisposes patients to developing upper urinary tract infections
MCUG used to diagnose

with oral antibiotics for 3 days according to local guidelines, usually trimethoprim, nitrofurantoin, cephalosporin or amoxicillin
children aged more than 3 months old with an upper UTI should be
considered for admission to hospital. If not admitted oral antibiotics such as cephalosporin or co-amoxiclav should be given for 7-10 days
Ix for haematuria and proteinuria?
> urinalysis
FBC, u&Es, clotting
ACR
GFR
Primary nocturnal enuresis
where the child has never managed to be consistently dry at night.
Causes of PNE?
> Most common: variation of normal development
OAB
Fluids before bed
failure to wake
secondary causes of PNE?
chronic constipation, urinary tract infection, learning disability or cerebral palsy
first line PNE?
The initial step in management of primary nocturnal enuresis is to establish the underlying cause. It can be helpful to keep a2 week diaryof toileting, fluid intake and bedwetting episodes
management of PNE?
> Reassurance of under 5s that it is likely to resolve w/o Tx
lifestyle changes
treat underlying causes like constipation
eneuresis alarms
what is secondary NE?
> where a child begins wetting the bed when they have previously been dry for at least 6 months. This is more indicative of an underlying illness than primary enuresis.
Causes of secondaru NE?
> UTI
const
T1D
psych problems or maltreatment
what is diurnal enuresis?
daytime incontinence. Dry at night but episodes of incontinence during the day
2 types of diurnal eneuresis?
> Urge incontinence is an overactive bladder that gives little warning before emptying
Stress incontinence describes leakage of urine during physical exertion, coughing or laughing.
meds for eneuresis?
> desmopressin
oxybutinin
imipramine
primary assessment of child w decreased LOC?
> ABCDE
D: use GCS or ACVPU
What would suggest ICP in a previously normal child?
decorticate or decerebrate positioning
CI of LP?
> Signs of raised ICP
neurological signs
prolonged/ focal seizures
GCS under 13
dilated pupils
Dolls eye reflex
abn posture - decorticate or decerebrate
coag disorder
dolls eye reflex?
> CI of LP
eyes should move opp to head movement
if dolls eye reflex is absent and eyes move W the head -> BS dysfunction
cushings triad?
> slow HR
abn breathing
Widening pulse pressure (raised bp)
> late sign of raised ICP
Mx of ICP?
> reduce pCO2 by hyperventillating
Head elevation to 30
mannitol or hypertonic saline
catheter and monitor u/o
Mx of oedema in a SOL?
Dexamethasone
cerebral perfusio pressure?
> cerebral perfusion pressure (CPP) is the net pressure gradient causing cerebral blood flow to the brain
CPP = mean arterial pressure - ICP
causes of raised ICP?
> Idiopathic intercranial HTN
traumatic head injuries
hydrocephalus
meningitis
tumours
features of raised ICP?
> headache
vomiting
reduced levels of consciousness
papilloedema
Ix for raised ICP?
> CT/MRI - looking for underlying cause
ICP - removing CSF?
> repeated lumbar puncture (e.g. idiopathic intracranial hypertension)
ventriculoperitoneal shunt (for hydrocephalus)
Immediate management of a child with raised ICP?
> abc assessment
Oxygen
GCS
tilt head up
O2
Mannitol
Dexamethasone
A?
> Consider intubation if GCS is <8 (or patient is unresponsive to pain on the AVPU), unless the child is showing signs of improvement.
> Give 100% oxygen if oxygen saturations are ≤95%.
Circ?
Circulatory compromise should be considered if one or more of the following are present:
> mottled, cool extremities
diminished peripheral pulses.
Consider circulatory shock if one or more of the following are present:
> systolic blood pressure is less than fifth percentile for age
decreased urine output <1 mL/kg/hour
differentials for decreased LOC?
> Meningitis
acute hydrocephalus
hypoglycaemia
intoxication
HTN
Sepis?
> htn
tachycardia
tachypnoea
WCC raised
non blanching rash
