Prader-Willi syndrome
• In infancy – Hypotonia
(‘floppy baby’)
– Feeding difficulties w/ FTT
• Then btwn 1- 6yrs old: – Rapid wt gain w/ central obesity
– Hyperphagia w/ food-seeking, hoarding & foraging behaviors
Prader-Willi syndrome
Genetic cause:
• Paternal deletion of a small part (15q11-q13) of chromosome 15 (70%)
• UPD maternal uniparental disomy of chromosome 15 (25%)
• Imprinting problem on chromosome 15 (<5%)
at 15q11-q13 (increased risk of recurrence)

PWS-Common characteristics
• Obesity
• Short stature w/ decreased levels of growth hormone
• Small hands & feet
• Almond-shaped eyes
• Hypogonadism
3 Causes of Obesity in PWS
• Hyperphagia w/ decreased satiety
• Decreased caloric requirements likely d/t hypotonia, decreased activity & short stature
• High threshold for vomiting & decreased pain perception (eating large quantities without discomfort)
PWS
• Obesity-related illness:
–Diabetes
–HTN
–Hyperlipidemia
– Sleep apnea (ST memory impairment)
–Pica
–Cellulitis (skin-picking)
PWS
• Elevated tolerance to pain
(may have injury or # but may not c/o pain)
• Decreased or absent vomit/gag reflex
• Thick viscous saliva: increased caries
• Thermoregulatory instability (masked fever)
• Osteoporosis( increased risk of # ), scoliosis, kyphosis
• Adrenal insufficiency (so check cortisol levels during times of severe illness or injury!)
• Seizures in 10-20% of PWPWS, but are relatively mild, are easily treated & often resolve w/ time
PWS: monitoring
• Developmental & educational assessment along with speech therapy assessment
• Assess males for cryptorchidism
• Strabismus in infants & children
• X-rays to r/o scoliosis
• Bone density to r/o osteoporosis, most likely will need calcium supplementation
• Annual BMI
• HgbA1C for those with significant obesity
• Sleep study to r/o sleep apnea
• Psych assessment to r/o OCD & psychosis

PWS - Intervention Strategies... Food issues:
**DO NOT USE FOOD AS A REWARD OR PUNISHMENT
• Caloric intake: 800-1200cal/day
• Calcium & vitamin supplements: high risk for osteoporosis
• Limit access (locks on cupboards, fridge)
• Environmental changes (PWS residences)
• Teach Heimlich maneuver to caregivers
PWS - Intervention Strategies...
Tantrums: (*verify if due to food issues!!)
• DO NOT ARGUE
• BE CONSISTENT (provide structure & routine)
• set firm limits
• written rules/contracts (with them)
• allow time to settle
• change the environment (quiet area)
• diversion, humour (but not sarcasm)
PWS - Intervention Strategies...
Skin-picking: • Reinforce + behavior • cut nails short • encourage alternative activities/distractions:
collages, scrapbooks, Play-Doh, playing cards, hand cream, puzzles (*scheduling)
• bandaids may be helpful as an initial layer to be removed before skin-picking can occur (liquid bandaid, long term drsg-duoderm/allevyn)
• HANDWASHING!!!!!
• N-Acetylcysteine & Topiramate has helped some for skin-picking
Intervention Strategies Educational strategies:
• a.m. classes when person is more alert
• consistency with breaks, lunchtime
• demo’s, pictures, models to teach
• specific choices (ex. red or blue crayon not which one)
• Nurturing: encourage helping others, taking care of pets (Jobs? Volunteer opportunities?)
• using puzzles (jigsaw) => provides flow!
• extra physical activities: Regular exercise, toning & strengthening exercises, cycling, skating, dancing, trampoline use & PT all can help maintain healthy weight
Intervention Strategies Psychiatric considerations:
• OCD (food rituals - but may also make poor food
choices, hoarding, ordering, repeating)
• Depression
• Psychosis (more common in UPD: ~ 100%)
• ASD (more common in UPD: ~ 38%)
• Anxiety
SSRIs helpful for OCD, psychosis & mood
GHRT: Growth hormone replacement Tx
• Improves final adult height, muscle tone, BMD & lean body mass, & decreases body fat.
• Increases energy, activity & strength, respiratory muscle forces.
• Body shape & facial features may normalize if Tx started early (age 2 or earlier)
• May even have some cognitive benefit!
• However, should be started in infancy, if possible
• But NEED SLEEP STUDY FIRST to assess for OSA (tonsils & adenoids may grow quicker than the pharynx if OSA is left untreated & GHRT started!)

PWS- Strategies • Replacement of sex hormones for hypogonadism
in boys may be helpful.
• May require Sx for undescended testes
• Modafinil may be helpful for daytime sleepiness
• No medications are known to aid in controlling hyperphagia yet…. – The Rhythm drug, RM-493
– The Zafgen drug, beloranib

Angelman Syndrome • Identified in 1965 by Dr. Harry Angelman • “Happy Puppet” until 1982 : I/DD, laughing ++, ataxic
gait, complex communication needs Genetics of AS: • Microdeletion on maternal chromosome 15 (75%) • UPD uniparental disomy (paternal X2) (3%)
(low recurrence risk) • Imprinting defects on maternal chromosome 15
(deactivated UBE3A section) (2%) (increased risk of recurrence)
• UBE3A mutation (5-10%) more common in familial AS (increased risk of recurrence)
• Mosaicism
Angelman syndrome
• Epilepsy (86-96%), most by age 3, with a very typical EEG (rhythmic slow wave + sharp/spike activity)
(May have non-convulsive status (just a little ‘off’))
• Ataxia (100%)
• Scoliosis (more common w/ advancing age)
• Strabismus (42-75%)
• Sleep problems common
• Complex Communication Needs
(expressive impairment > receptive impairment, difficulties with labelling, describing & echoing/imitating sounds/words)
• Individuals w/ UPD, may have less severe ataxia, seizures & language impairments
2017 DDNA Annual Conference
02/03/2017
Terry Broda, NP, CDDN 5
Epilepsy in AS
• Baseline MRI & EEG to assess for epilepsy (*AVOID AEDs that increase GABA levels –vigabatrin (Sabril) & tigabine Also avoid phenobarbitol, carbamazepine, oxcarbazepine as they may
exacerbate myoclonus)
Some helpful Therapies: • Clobazam (Onfi) & benzodiazepines: BDZ (broad coverage but
may worsen absence sz) • Ethosuximide (Zarontin) ESM (vs absence & myoclonic sz only) • Lamotrigine (Lamictal) LTG (helpful but may exacerbate
myoclonus in higher doses) • Levetiracetam (Keppra) LEV (vs myoclonus & atypical absence) • Topiramate (Topamax) TPM (convulsive & focal sz) • Valproate (Depakote) VPA (vs all sz types) • Ketogenic/LGI (low glycemic) diet (broad spectrum & can help
all sz types) Tx to avoid prolonged, frequent seizures that would impact on cognitive function & learning: BALANCE!
AS: monitoring
• Baseline MRI & EEG to assess for epilepsy (*AVOID AEDs that increase brain GABA levels –vigabatrin &
tigabine) (VPA ++SE, LMG & Lev also but CLBZ OK!)
• Adults may also have non-epileptic myoclonus (does not respond as well to meds, CLNZ ok)
• MSK exam: assess ataxia & scoliosis: w/ age • Ophthalmology consult to r/o strabismus & assess
visual acuity • Assess for FTT (tongue movements/protrusion => swallowing
problems), GERD & constipation • Consults for communication & educational
strategies, SLP, PT & OT
AS-Intervention Strategies... Communication strategies: • Offer choices (2) & provide item ASAP • Sign language, may be simple gestures • Objects of reference (Velcro straps for travelling, if this is
the only time they use straps; toothbrush, hairbrush, piece of quilt from bedding for sleep)
• Miniatures (smaller hairbrush, toothbrush, spoon, etc)

Anesthesia considerations
• No specific concerns re. anesthetic agents used, even though those w/ microdeletion also have deletion of GABA receptor gene & this is commonly the receptor for benzos
• Caution w/ various agents d/t seizures in persons w/ AS
• Anecdotal incidents of bradycardia due to increased activity of the vagus nerve

2017 DDNA Annual Conference
02/03/2017
Terry Broda, NP, CDDN 11
Intervention Strategies...
Anxiety/Fear:
• provide reassurance (but with set limits to attention-seeking behavior)
• Use distraction by changing topics after initial reassurances
• CBT-cognitive behavioral therapy
• Pharmacotherapy (*with caution!): start with low doses since WS persons are Rx-sensitive (Ex. Ritalin, tricyclics & )
WS - Intervention Strategies

• Use ‘buddy system’ to practice social skills, role-plays, & social stories
• Topics to cover: how to make & keep friends, approaching others, taking turns, conversational skills, dealing with romantic issues & sexuality, how & why to be wary of strangers
• Group therapy can increase self esteem (but may not be appropriate for some d/t anxiety or ADHD)
Chronic Constipation
Monitoring:
• Bristol stool form
Positioning : legs bent at the knee, with thighs elevated to h pressure on the abdomen (crouching) (rocking on the seat)
• Interventions:
• Stool softeners to maintain regularity & prevent rectal prolapse
PKU video
Phenylketonuria
• Inborn error of metabolism
• Phenylalanine hydroxylase (PAH) deficiency results in intolerance to the dietary intake of the essential amino acid phenylalanine (Phe) and produces a spectrum of disorders including phenylketonuria (PKU), non-PKU hyperphenylalaninemia (non-PKU HPA), and variant PKU
• Autosomal recessive
PKU
• Blond/light hair (increased phenylalanine inhibits melanogenesis)
• Sclerodermoid changes
• Generalized hypopigmentation
• Blue eyes
• Eczematous dermatitis
• Developmental disability
• Hyperreflexia, spasticity
• Seizures
• SIB, aggression, ADHD, pica

PKU
In the hours after a protein-rich meal, persons with PKU will often experience:
–Nervousness
– Fatigue
–Difficulty concentrating
–Problems memorizing
–Difficulty completing complex tasks
Phenylalanine
• Essential amino acid : the body cannot produce it so it comes from food
• Source of Phe: in foods containing proteins that break down into amino acids: – Meat & substitutes (fish, eggs, nuts & grains,
legumes) +++
– Milk products +++
– Cereals ++
– Fruits & vegetables +
– Aspartame +++
PKU- Dietary principles
• Monitor Phe levels
• Assure adequate protein & caloric intake to keep Phe levels within safe range
• Consistency (no cheating!)
• Dietician: dietary intervention for life & needs to start ASAP!
PKU diet
• Phenylalanine : A restricted intake of Phe is necessary but a
minimim amount is required by the body. Low Phe levels can lead to other problems:
lethargy, anorexia, anemia, dermatological issues and diarrhea.
– Females > 19yrs: 220-700mg/day –Males > 19yrs: 290-1200mg/day
PKU Diet • Fruits & vegetables +++ • No meat or substitutes • No milk products or limited amounts • No restriction (other than for weight concerns!) • « Tang », regular colas, tea, coffee, iced tea,
vegetable oil, Jello, clear candies, honey, regular popsicles…
• ►ALL foods can contain some Phe so it NEEDS to be calculated :
• Can be used as a “limited intake treat”. • 15mg = 1 treat
PKU Diet
• Frequent bldwk to monitor Phe levels in early yrs (q. week eventually q. month)
• Phe levels btwn 2-6mg/dl (120-360μmol/L)
• Abnormal bloodwork:
wait for 2 elevated Phe results before adjusting the diet & then suggested Phe dietary decrease by 10%
• Regular monitoring of weight & adjust diet accordingly
2017 DDNA Annual Conference
02/03/2017
Terry Broda, NP, CDDN 13
Medication: sapropterin (Kuvan)
• Increases tolerance to phenylalanine
• To use in combination w/ PKU diet
• More long term studies needed to determine true efficacy & safety in the long-term
