Normal hormone,normal male sperm study and normal menses: still canโ€™t conceive then give TRY with clomiphene, that is Antagonist at GnRH receptor at Hypothalamas, Block Estrogen mediated inhibition of GnRH hence Increase release of GnRH>>>>>>inc. LH surge ovulation Bromocriptine - would be helpful if the pt has infertility due to INCREASE PROLACTIN. DES - is stopped in US due to clear cell carcinoma in young female born to mother. Ethinyl estradiol - bind estrogen recepto>>>>>inhibit GnRH >>>>no LH surge: no use (inc. Risk of endometrial carcinoma) Medroxyprgestroene - is progestrin โ€”-bind progesterone receptor....is(component of morning after pill)

This baby has abetalipoproteinemia. ("without Beta apolipoproteins"). Thus they will lack B-48 and B-100 and have absent levels of chylomicrons, VLDL, and LDL. Infants present with severe fat malabsorption and deficiencies of all fat soluble vitamins (ADEK). Lack of vitamin A renders them vulnerable to Retinitis pigmentosa and lack of VitE leads to spinocerebellar degeneration.

Positive staining for synaptophysin and chromogranin are immediate buzzwords for neuroendocrine tumors. Paragangliomas are the only type listed here.

Others would be small cell carcinoma of lung, carcinoid tumor, gastrinomas/insulinomas/etc, pheos, medullary carcinoma of thyroid.
