Q

what is acrodermatitis enteropathica? What does it cause?

A

zinc deficiency, autosomal recessive

dermatitis around mouth and in limbs, diarrhea, alopecia

24
remembering caloric requirements / kg?
1500 for first 20kg, then 29 cal/kg for each additional
25
How many kcal/kg/day to term and preterm infants require?
100-120 kcal/kg/day
26
Premature infants require how much protein | Full term infants require how much protein
preterm: 3.5 g/kg/day term: 2-2.5 g/kg/day x mos
27
major reason post-op infant isn't gaining weight?
incr UOP b/c of incr renal solute load
28
what are the important components of renal solute load?
sodium, potassium, chloride, phosphorus
29
An essential fatty acid?
lineoleic acid
30
recommended concentration of iron in iron fortified formula?
12mg/L
31
which infants require iron supp
preterm, LBW before 6 mos, no matter what
32
what classifies a low iron formula, and when should it be used?
1.5mg/L, never use it.
33
infant with scaly dermatitis, alopecia, TCP?
Essential fatty acid (lineoleic acid) deficiency
34
Edema, Erythrocyte explosion (hemolytic anemia), elevated Plts caused by what deficiency?
Vit E def
35
Zinc deficiency may be apparent in what time/event period?
when weaning from breast milk b/c it contains protein that facilitates zinc absorption
36
When to give protein hydrolysate formula?
soy protein allergy or milk protein allergy
37
What type of fat should preemies get?
medium chain TGs, b/c they have decr bile salts, but these aren't sufficient for essential FAs. Preemie formulas have 50% total fat from MC TGs vs 12% in regular breast milk
38
What acids are decreased in mature breast milk vs colostrum
arachidonic acid (AA) and docosahexaenoic acid (DHA) for neuro development
39
Colostrum vs mature milk? | which has more protein, fat, lactose, energy?
Colostrum has higher protein. | Mature milk has higher fat, lactose, energy
40
cow's milk vs human milk on calcium, phosophorus?
breast milk has less phosphorous. Cow's milk has a lot, so if its given to kid < 12 mos, they will get too much and develop low Calcium. (hypocowlcemia)
41
When no breast feeding?
Rx: flagyl (for trichomonas), diazepam, antithyroid meds, tetracycline, sulfonamides HIV, HSV on breast CMV / TB radioactive meds/chemos, Errors of metab: galactosemia, PKU, Urea cycle defects
42
How long should breast feeding be stopped for for technetium 99 scan?
1-2 days (contraindication to radioactive rule)
43
Protein concentration in Human milk, cow milk, modified cow formula.
Human milk has 0.9 g/dL Cow milk 3.5 g/dL Formula 1.4 g/dL
44
whey: casein is highest in what kind of milk? | What type of whey in cow vs human milk?
human milk is 70% whey (alpha lactalbumin), 30% casein VS | Cow milk: 20% whey (beta lactalbumin)
45
why is alphalactalbumin in human whey milk better?
its got more lactoferrin, lysozyme, IgA for easier digestion
46
calcium: phosphorous ratio in human milk vs cow formula
human milk: 2:1 cow formula: 1.5:1 (more phosphorous in formula...)
47
protein requirement for preemies
3-4 g/kg/day vs 2-3 in full term
48
Big thing to avoid in preemies w/ regard to protein intake
negative nitrogen balance which causes wt loss
49
role of lactose in milk?
for infants: inhibits bacterial adhesion to mucosal surface, reduces risk of bacterial infx.
50
typical wt gain for newborn per day and how many cal? | preemies?
20-30 g/day, requires 100 cal/kg/day | Preemies 15-20 g/day on 120cal/kg/day
51
obesity: distinguishing from overeating vs hormonal/genetic?
overeating: tall, advanced bone age | hormonal / genetic: short, delayed bone age
52
chance of obesity if present at age 6 vs age 12?
25% --> 75%
53
head / craniotabes w/ delayed suture and fontanel closure, frontal bossing and bad tooth enamel should lead to consideration of ?
Rickets
54
marasmus hallmark?
severe nutritional deficiency: muscle wasting w/o edema, normal hair
55
most common complication of NGT feeding?, 2nd? | most severe?
diarrhea, GERD | most severe: vomiting w/ aspiration
56
poor feeding, irritability, metaphyseal irregularity, normal vitD,neutropenia? Who is at risk? How to supplement?
copper def preterm babies receiving inappropriate trace element supplementation with their parenteral nutrition Copper 200mcg / L
57
si/sx of magnesium def?
hypotonia, apnea
