22
Q
causes of congenital hypothyroidism
A
MCC= maldescent and athyrosis
dyshormonogenesis
MCC WORLDWIDE= iodine def
TSH deficiency= panyhypopit
23
Q
tx DKA
A
- fluids– slowly over 48-72hours
+ monitor fluid status
2……….insulin (after 1 hour of fluids), after 24hrs– blood glucose around 14mmol/L - potassium– ONCE URINE PASSED, monitor heart
- acidosis– self corrects,; only give bicarb if in shock
- re-establish oral fluids, sc insulin, diet [only stop IV insulin once oral given for 1 hour)
- ID and Tx underlying cause
24
Q
other autoimmune diseases associated with diabetes
A
celiac
hypothyroidism
addisons
25
monitoring for DMT1 complications
yearly:
- HTN
- kidneys-- microalbuminuria
- hypothyroidism
3 years:
- celiac screen
5 years:
- retinopathy/cataracts
26
permanent neuro sequelae of hypoglycaemia
1. epilepsy
2. developmental
3. microcephaly
27
causes of hypoglycaemia - insulin XS
1. OD
2. nesidioblastosis/ insulinoma
3. autoimmune Ab to receptor
4. beck with syndrome
5. sulphonylureas
28
causes of hypolgycaemia- no insulin XS
1. liver disease
2. ketotic hypoglycaemia of childhood
3. glycogen storage disorder
4. hormonal def-- GH, ACTH
29
causes of hypoglycaemia= reactive
1. galactosemia
2. fructose intolerance
3. leucine sensitivity
4. hormonal def
5. alcohol or aspirin poisoning
6. maternal diabetes
30
Diagnosis of hypoglycaemia
CONFIRM BLOOD GLUCOSE
| --- then run through the labs specific to the numerous causes
31
Tx of hypoglycaemia from weird causes
1. glucose 10% ml/kg dextrose, followed by 10% dextrose infusion
2. IM glucagon
3. corticosteroids-- hypopituitarism, hypoadrenalism
32
thyroid hormones kids
fetal= reverse T3= inactive
| at birth SURGE TSH, then decreases, normalises at 1 week
33
causes of congenital hypothyroidism
MCC= maldescent
dyshormonogenesis
MCC WORLDWIDE= iodine def
TSH deficiency= panyhypopit
34
PC juvenile hypothyroidism/ acquired
- goitre
- loss of eyebrow hair
- coarse skin
- dry hair
- cold
- bradycardia
neurodevelopment decreased
- decrease reflexes
SUFE
obesity

juvenile hypothyrodism a/w which two syndromes
DOWNS
TURNERS
36
what autoimmune diseases a/w juvenile hypothyroidism
```
V.RAD
vitiligo
RA
addisons
DM
```
37
difference in presentation of hyperthyroidism in kids
NO EYE SIGNS
38
Two NB bone things for hyperthyroidism in kids
rapid growth height
| advanced bone maturity
39
true or false, maternal TSI antibodies can cross the placenta
TRUE! IgG
40
causes of hypoparathyroidism
1. preme- common
2. DiGeorge
3. Addisons-- older
4. McCune Albright syndrome
