Evaluation of hemoptysis
-mild/moderate ==> workup +/- CT +/- broncoscopy if needed -massive (600/24hr or 100/hr) ==> intubate/secure airway -bleeding stops ==> workup -bleeding continues ==> bronchoscopy
Bilateral renal agenesis of fetus ==>
incompatible with life
Lower intestinal pathology assoc. w/Down’s
Hirschsprung
Causes of precocious puberty
-central ==> high FSH & LH -peripheral ==> low FSH & LH (e.g. excess peripheral conversion, estrogen-producing ovarian cyst, CAH)
NF1 features
-cafe-au-lait -macrocephaly -feeding problems -short stature -learning disabilities ==> fibromas, neurofibromas, other tumors

Definition of precocious puberty
secondary sex characteristics @ :
girls < age 8
boys < age 9
Evaluation of precocious puberty
- bone age
- normal ==> premature thelarche (breast development) vs. premature adrenarche (pubic hair development)
- advanced ==> basal LH
- basal LH
- high ==> central
-
low ==> GnRH stimulation test
- low LH ==> peripheral
- high LH ==> central
Neurologic deficits in B12 deficiency
- loss of distal vibration sense & proprioceptive sense
- memory loss, irritability, dementia
Tx of megaloblastic anemia w/folic acid alone ==>
- if 2/2 B12 deficiency, folic acid will correct anemia but accelerate neurologic sx of B12 deficiency
Evaluation of gastric adenocarcinoma
- may be discovered by biopsy during endoscopy
- stage w/CT scan
