  • monosomy 7 syndrome associated with congenital adrenal hypoplasia and Male Pseudohermaphroditism
    Obstetrics & Gynecology, 1996
    Co-Authors: Sy Q Le, William H Kutteh
    Abstract:

    Background: Bone marrow monosomy 7 is an uncommon disorder of the pluripotent stem cells that leads to frequent childhood infections and leukemia. Primary adrenal hypoplasia occurs very rarely and is incompatible with life. Male Pseudohermaphroditism results from inadequate androgen secretion or inappropriate androgen action. We report a case of monosomy 7, adrenal hypoplasia, and Male Pseudohermaphroditism. Case: An infant was born with sexual ambiguity and bilateral inguinal masses. Bone marrow karyotype was 45,XY,-7. Serum testosterone level was low normal. The infant died on the fourth day of life. Autopsy revealed severely hypoplastic adrenal glands, inguinal testes, and a vaginal pouch. Conclusion: Monosomy 7 and Male sexual ambiguity are reported in association with primary adrenal hypoplasia of the cytomegalic (X-linked) type.

  • nongenetic Male Pseudohermaphroditism and reduced prenatal growth
    The New England Journal of Medicine, 2001
    Co-Authors: Berenice B. Mendonca, Ana Elisa C Billerbeck, Francis De Zegher
    Abstract:

    To the Editor: Most cases of Male Pseudohermaphroditism have a genetic origin.1 A nongenetic variant of the disorder, characterized by reduced prenatal growth and the lack of evidence of any associated malformation or endocrinopathy,2 has not been established. We report here on a pair of twins (karyotype, 46,XY) who were born at term after a normal gestation sustained by one placenta. Monozygosity was corroborated by identity for seven informative DNA loci in six chromosomes (D5S818, D13S317, D7S820, VWA, FGA, THO1, and CSF1PO). One boy (birth weight, 3.0 kg; length, 48 cm) had normal genitalia. The twin (birth weight, 1.7 kg; . . .

  • normal bone density in Male Pseudohermaphroditism due to 5alpha reductase 2 deficiency
    Revista do Hospital das Clínicas, 2001
    Co-Authors: Elaine M F Costa, Marlene Inacio, Ivo J. P. Arnhold, Berenice B. Mendonca
    Abstract:

    RHCFAP/3050COSTA EMF et al. - Normal bone density in Male Pseudohermaphroditism due to 5α-reductase 2 deficiency. Rev. Hosp. Clin.Fac. Med. S. Paulo 56 (5):139-142, 2001.Bone is an androgen-dependent tissue, but it is not clear whether the androgen action in bone depends on testosterone or ondihydrotestosterone. Patients with 5 α-reductase 2 deficiency present normal levels of testosterone and low levels of dihydrotestosterone,providing an in vivo human model for the analysis of the effect of testosterone on bone.Objective: To analyze bone mineral density in 4 adult patients with Male Pseudohermaphroditism due to 5α-reductase 2deficiency.Results: Three patients presented normal bone mineral density of the lumbar column (L1-L4) and femur neck, and the otherpatient presented a slight osteopenia in the lumbar column.Conclusion: Patients with dihydrotestosterone deficiency present normal bone mineral density, suggesting thatdihydrotestosterone is not the main androgen acting in bone.DESCRIPTOR: Bone mineral density. Male Pseudohermaphroditism. 5 α-reductase type 2 deficiency.It has been well documented in theliterature that gonadal steroids regulatenormal bone metabolism and that in-adequate estrogen concentrations in fe-Males and androgen concentrations inMales cause osteoporosis
