A histochemical and ultrastructural study of human breast carcinomas with a view to their classification by cell of origin
(Experimental and Molecular Pathology, 1979-08)
We have studied 450 cases of human breast carcinoma at the histochemical and ultrastructural level. The breast biopsies were obtained from Canada, Mexico and Dominican Republic.This study was undertaken to evaluate the ...
Urinary steroid metabolites in subjects with male pseudohermaphroditism due to 5α-reductase deficiency
(Wiley, 1985-07)
To investigate the enzymatic basis for abnormal steroid metabolism in subjects with male pseudohermaphroditism due to 5α-reductase deficiency, the ring A reduced urinary 5β and 5α metabolites of testosterone, androstenedione, ...
Androgens and the evolution of male-gender identity among male pseudohermaphrodites with 5alpha-reductase deficiency.
(New England Journal of Medicine, 1979-05-19)
To determine the contribution of androgens to the formation of male-gender identity, we studied male pseudohermaphrodites who had decreased dihydrotestosterone production due to 5 alpha-reductase deficiency. These subjects ...

Testicular function in 2 cases of penile agenesis
(The Journal of Urology, 1981-10-05)

Male pseudohermaphroditism due to multiple defects in steroid-biosynthetic microsomal mixed-function oxidases — a new variant of congenital adrenal hyperplasia
(New England Journal of Medicine, 1985-11-07)
A six-month-old 46,XY infant with a female phenotype and ambiguous genitalia was evaluated for male pseudohermaphroditism. The principal findings were (1) low basal plasma levels of all measured C19 steroids and their ...
Decreased Urinary C19 and C21 Steroid 5α-Metabolites in Parents of Male Pseudohermaphrodites with 5α- Reductase Deficiency: Detection of Carriers
(The Journal of Clinical Endocrinology & Metabolism, 1985-05-01)
The urinary 5β/5α ring A-reduced metabolites of C19 and C12 steroids from obligate carrier parents of male) pseudohermaphrodites with 5a-reductase deficiency were analyzed by gas chromatography. Etiocholanolone/androsterone, ...
Reversibility of catecholamine-induced dilated cardiomyopathy in a child with a pheochromocytoma
(N Engl J Med, 1987-03-26)
Patients with a severe, dilated cardiomyopathy with congestive heart failure have a poor prognosis unless a correctable cause can be identified. Even when a cause is found, the degree of reversibility of myocardial injury ...
