Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder commonly caused by mutation of the CYP21A2 gene, resulting in deficiency enzyme required for cortisol synthesis cortex. In 90-95% cases, deficient 21-hydroxylase (21-OH), with incidence ranging from 1 5,000 to 15,000 live births across various ethnic and racial backgrounds. classical 21-OH (21-OHD) CAH, excessive androgen e...
Obesity is linked to increased incidence of endometrioid endometrial cancer (EEC) and complex atypical hyperplasia (CAH). We here explore pattern and sequence of molecular alterations characterizing endometrial carcinogenesis in general and related to body mass index (BMI), to improve diagnostic stratification and treatment strategies. We performed molecular characterization of 729 prospectivel...
Congenital adrenal hyperplasia (CAH) is a well-recognized, but uncommon, cause of azoospermia and infertility in men. Commonly this is due to undertreatment of excessive adrenal androgen secretion which suppresses gonadotrophin stimulation of the testes. A less common complication of CAH is development of adrenal tissue within the testes; this is important to recognize because it may be confuse...
Receptor-type protein tyrosine phosphatase beta (RPTP beta) is expressed in the developing nervous system and contains a carbonic anhydrase (CAH) domain as well as a fibronectin type III repeat in its extracellular domain. Fusion proteins containing these domains were used to search for ligands of RPTP beta. The CAH domain bound specifically to a 140 kDa protein expressed on the surface of neur...
We describe a patient with signs and symptoms of virilization caused by 21-hydroxylase deficiency. The patient, a Hispanic woman, first sought medical attention at age 24, when she presented to a medical clinic with an uncomplicated urinary tract infection. At that time several signs of virilization were noted and she was referred to the endocrinology clinic. Evaluation revealed temporal baldin...
There is considerable controversy about the origins of sex differences in cognitive abilities, particularly the male superiority in spatial abilities. We studied effects of early androgens on spatial and mechanical abilities in adolescents and young adults with congenital adrenal hyperplasia (CAH). On tests of three-dimensional mental rotations, geography, and mechanical knowledge, females with...
Three distinct isolates of Candida albicans were used to establish systemic and oral infections in inbred mice that are genetically resistant or susceptible to tissue damage. Patterns of infection differed significantly between both yeasts and mouse strains. Systemic infection conferred significant protection against re-challenge with the homologous, but not the heterologous yeast; however, the...
RÉSUMÉ. L’hypothèse de cluster est l’hypothèse fondamentale de l’utilisation du clustering dans la recherche d’information. Elle indique que les documents semblables ont tendance à être pertinents pour la même requête. Des travaux passés testent intensivement cette hypothèse avec les méthodes de la classification ascendante hiérarchique (CAH). Mais leurs conclusions ne sont pas cohérentes en te...
Congenital adrenal hyperplasia (CAH) resulting from 17α-hydroxylase/17,20-lyase deficiency is a rare autosomal recessive disease and the second most common form of CAH in Brazil. We describe the case of a Brazilian patient with CYP17 deficiency (17α-hydroxylase/17,20-lyase deficiency) caused by a homozygous p.R96W mutation on exon 1 of the CYP17 gene, an unusual genotype in Brazilian patients w...
