What to ask in hx of constipation
Stool pattern (size, consistency, interval)
Large bowel movements suggest constipation
History of constipation/soiling (onset)
Incontinence during sleep suggesting constipation
Diet history (type and amount of food, changes in diet)
Decrease in appetite
Abdominal pain
Medications
Urinary symptoms (day or night enuresis, UTI)
Family history of bowel disease
Family/personal stressors
Toilet training, separation, change in schedule
Management of constipation/ retention encopresis
PEG 3350 1-1.5 g/kg PO daily x 3-6 days or until loose stool, then maintenance 0.4g/kg daily
Assessment and guidance regarding psychosocial stressors
Behavioural modification
Positive association with toilet sits
Schedule regular 3-5 times daily toilet sits (eg. after each meal)
While sitting, offer proper foot support, and enjoyable relaxing activities
Ensure soft, well formed stools
What to ask in hx of enuresis

Stool history (Constipation, encopresis)
Treatment of primary nocturnal enuresis
Reassurance (15% resolve spontaneously each year)
Behaviour modification
Limit fluids/caffeine
Void prior to sleep
Ensure easy access to toilet
Remove diapers
Include child in morning cleanup in non-punitive manner
Motivational therapy (eg. star chart)
Bladder retention exercises
Scheduled toileting overnight
“Wet” alarm wakes child upon voiding (70% success)
Consider referral if inadequate response to enuresis alarm

Slipped capital femoral epiphysis (SCFE)
Legg-Calvé-Perthes disease (LCP) / Avascular necrosis
Neoplastic (night-time pain, unrelated to activity, systemic symptoms, anemia, leukopenia, thrombocytopenia, high LDH or uric acid)
What hip XR views should you get in peds?
(anteroposterior and frog-leg views)
What does an XR vs US vs MRI r/o in ped hip pain?
Hip X-ray
r/o trauma, malignancy, advanced (not early) LCP, JIA, SCFE
Hip Ultrasounds
r/o effusion (bilateral suggestive of transient synovitis, unilateral r/o septic arthritis consider joint aspirate)
MRI
r/o osteomyelitis, early LCP, and early SCFE
What criteria to use to r/o septic arthritis + how to Ix?
Kocher Criteria
Non-weight-bearing on the affected side
ESR > 40 mm/hr
Fever
WBC count > 12,000
If low pre-test probability + negative hip US for effusion, outpt FU
If moderate pre-test probability
Negative U/S
If <24h, Repeat U/S in 12h or MRI
If >24h, Outpatient follow-up
If positive ultrasound -> Arthrocentesis for synovial fluid analysis

Buckle fracture features, management
Usually FOOSH
Removable wrist (volar) splint x 2-4 weeks
Start ROM if at 2w no tenderness (discontinue immobilization)
No need for repeat X-rays
Non-displaced greenstick fracture management
Short-arm cast x 2-4 weeks
displaced greenstick fracture management
Displaced >10 degrees angulation
Closed reduction (gentle steady pressure for physeal) under conscious sedation
Long-arm cast (elbow 90 degrees flexion, forearm in neutral rotation, and wrist in neutral flexion-extension
Repeat X-rays weekly
Remove cast at 4 weeks if healed clinically and radiographically
non displaced physis fracture management
Non-displaced (if X-rays normal initially, tenderness over growth plate, immobilize x 2 weeks, re-image and re-assess)
Short-arm cast x 3-6 weeks
What to assess on an elbow fracture
Assess Vascular (Brachial) and Nerve (Ulnar/Anterior Interosseous Nerve)
Capillary refill, distal neurovascularity
Immobilize at flexion 20-30 degrees (least nerve tension) before X-rays to avoid further injury
How to approach elbow XR, what signs are you looking for
Fat pad (sail) sign, posterior always indicates effusion (rule out fracture)
Anterior humeral line should intersect middle 1/3 of capitellum (if not think supracondylar fracture)
Radiocapitellar line shoulder intersect capitellum, if not think radial head dislocation (rule out Monteggia fracture-dislocation)
Remember CRITOE (Capitellum, Radial head, Internal epicondyle, Trochlea, Olecranon, External epicondyle)
Age 1, 3, 5, 7, 9, 11
Consider image bilaterally
Rx for supracondylar fractures
For non-displaced, neurovascular intact
Long arm posterior splint then long arm casting with less than 90° of elbow flexion x 4 weeks with repeat X-ray
Rx for lateral condylar fractures
FOOSH + Varus force
Non-displaced
Posterior splint, elbow 90°, weekly follow-up, if stable x2 weeks long-arm cast for 4-6 weeks
Proximal humerus acceptable deformity
Age 1-4yo = 70° without displacement
Age 5-12yo = 40° and displacement <51% width of shaft
Age >12yo = 15° and displacement <30% width of shaft
Rx for prox humerus fractures
discuss conservative measures and consider Sarmiento brace with repeat X-rays in 2 weeks
Clavicular fracture features + management
Most commonly middle third of clavicle after fall on shoulder (or may be from FOOSH)
Broad arm sling (or figure of 8) 2 weeks until comfortable and fracture site non-tender
Repeat X-ray if lateral third fracture at 1 week (no repeat X-ray at middle-third)
ROM as tolerated (elbow/wrist/hand ROM throughout recovery)
Return to non-contact sports 6 weeks after injury
Avoid contact sports 1-2 months after healing
Advise that bony deformity possible
Refer to ortho if displaced medial or lateral third fracture
Feature’s of toddlers fractures
Children <2yo learning to walk (often no history of trauma)
Fall with twisting motion or from significant height
Spiral fracture of distal/middle tibia (13-43% initial X-rays negative)
Pain with dorsiflexion of ankle
Rule out abuse (bruising, other fracture)
Rx for non-displaced fractures
Bent knee long-leg cast
X-rays weekly
May change to short-leg cast for 4-6 weeks if callus present
No evidence that casting speeds healing, but may decrease risk of displacement
Healing usually by 6-10 weeks
Varus deformity should remodel if <10 degrees
When to refer toddler’s fractures
Refer to ortho if open, pathologic, displaced >10 degrees anterior angulation, >5 degrees varus/valgus angulation, >1cm shortening, concurrent tibia/fobular fracture
