first pass elimination

A

extensive drug extraction and metabolism in liver immediately after gut absorption

19
Q

ASD diagnosis

A

deficits in social communication/interaction + restricted repetitive behaviors

20
Q

discontinuation syndrome with SSRIs

A

dizziness, confusion, nausea, abdominal cramps, sweating, dyesthesias, irritability

21
Q

Fragile X syndrome

A

MC inherited cause of IDD
mutation in FMR1 gene on x chromosome
elongated face, large ears, enlarged testicles

typically mutation is CGG trinucleotide segment repeat

common comorbid ADHD, ASD, Anxiety DO

up to 73% have axis 1 psych disorder

22
Q

common in Down syndrome pts

A

thyroid disorders. Should have FT4, TSH drawn at birth, 6 mo, 12 mo and annually

sleep apnea, 
hearing loss
otitis media 
vision and eye disease
hypodontia
neurologic dysfunction
gastrointestinal atresias
hirschsprung dz
hip dislocation 
autism
celiac conditions 
hematologic conditions 
atlantoaxial instability
23
Q

repeated vomiting, chewing, reingesting vomitus

does not occur during sleep
should not respond to standard medical therapy for reflux

24
Q

guanfacine

A

more selctive alpha adrenergic than clonidine
less sedation and longer duration
shows reduced tics and ADHD at doses 0.5mg BID to 1mg TID

25
Q

neurobiological feature of ASD

A

decreased formation of purkinje cells in cerebellum

increased overall head size, accelerated head growth during infancy

26
Q

FDA max doses for methyphenidate stimulants

A

dexmethylphenidate (focalin IR): 20mg

methylin, ritalin (SA, SR), and metadate (ER/CD)- 60mg

methylphenidate-oros (Concerta)- 72mg

methyphenidate patch (Daytrana)- 30mg

27
Q

lithium monitoring

A

q 6 mo

BUN, creatinine, TSH, calcium, lithium, ECG

can increase OR decrease thyroid. either goiter or hypothyroidism

28
Q

metabolic capacity of kid v adult

A

kids is higher
drugs must be given at shorter intervals.
kids have more efficient renal elimination of drugs and will excrete drugs faster
have greater extracellular water

29
Q

percentage of ODD that will go to CD

A

30%

30
Q

consequence of infantile anorexia

A

food refusal by infant leads to failure to develop somatopsychological differentiation, the abilty to differentiate sensations in the body

between 6mo and 3 years of age

feeding is directed by his or her emotinal needs instead of psysiological sensatios of hunger and satiety

31
Q

atomoxetine

A

selectively inhibits presynaptic norepi reuptake

p450 2d6

CI: pheocromocytoma, MAOIs, glaucoma

32
Q

TCAs

A

inhibit 5HT and norepi uptake

33
Q

kids v adults metabolism

A

higher metabolic capacity in kids

drugs in kids have to be given at shorter intervals

peds have more efficinet renal elimination, will excrete drugs faster.

greater vol of extracellular water in peds patints , drugs like litium will have lower plasma concentration compared to adults

34
Q

avoid this med in IDD

A

potent anticholinergic due to cognitive blunting
