What defines Short Stature?
|
measurements that fall below the 3rd percentile for height
|
|
|
What are the 4 basic patterns of proportional short stature?
|
1. Pathologic = postnatal onset
2. Constitutional growth delay 3. FAmilial Short stature 4. Prenatal onset short stature (IUGR) |
|
|
In this short stature, normal final adult height is reached, but the growth spurt & puberty are delayed
|
Constitutional Short Stature
|
|
|
Patients with this short stature stay parallel to the growth curve
|
Familial Short Stature
|
|
|
This short stature is parallel to the growth curve but is much more marked
|
Prenatal short stature (IUGR)
|
|
|
What is the single most important diagnostic study to obtain in short stature?
|
X-ray of the left hand & wrist for bone age
|
|
|
What are 3 endocrine causes of Tall Stature?
|
1. GH excess = gigantism & acromegaly
2. Androgen excess = tall as children but short as adults 3. Hyperthyroidism |
|
|
What are genetic syndromes & metabolic disorders responsible for Tall Stature?
|
1. Homocystinuria
2. Cerebral gigantism 3. Beckwith-Wiedemann = hereditary disorder characterized by exomphalos, macroglossia, and gigantism, often with neonatal hypoglycemia 3. Weaver-Smith 4. Klinefelter Syndrome |
|
|
What are the symptoms of Homocystinuria?
|
-Autosomal recessive
-Marfanoid appearance -Mental retardation -psychiatric illness |
|
|
This syndrome presents with large for gestational age, mental retardation, & a mild hydrocephalus
|
Cerebral Gigantism = Sotos Syndrome
|
|
|

|
|
|
Chronological Age > Bone Age
with abnormal growth velocity |
Chronic system disease or Endocrine disorders
|
|
|
Chronological age = Bone Age
with normal growth velocity |
Genetic short stature
|
|
|
Chronological age < Bone Age with normal growth velocity
|
Obesity
|
|
|
Chronological age < Bone Age with abnormal growth velocity
|
Precocious puberty
Congenital Adrenal Hyperplasia Hyperthyroidism |
|
|
A baby weighs 16 lbs at 1 year of age. Birth weight was 8 lbs. Parents state that the baby feeds well. Physical exam reveals a baby with little subcutaneous fat, long dirty fingernails, impetigo, & a flat occiput
|
Failure to thrive
|
|
|
What are the risk factors of FTT?
|
Malnutrition
-starvation, deprivation, abuse Malabsorption -infection, celiac dx, CF, Disaccharidase deficiency, protein-losing enteropathy Allergies Immune deficiency states Chronic disease |
|
|
What test should be considered in a FTT patient?
|
Sweat chloride for CF
|
|
|
What are the complications associated with Obesity? (4)
|
CV = HTN, high cholesterol
Hyperinsulinism Slipped Capital Femoral Epiphysis Sleep Apnea |
