[Adrenocortical carcinoma in women of reproductive age].

Adrenocortical carcinomas are rare tumors, usually hyperfunctioning, with poor overall survival. Frequent age of presentation is described in adults between 40 and 60 years of age, predominantly female. Two unusual cases of adrenal carcinoma diagnosed in young women are presented.

[Anti-estreptavidin antibodies. Diagnostic confusion by biochemical interference].

We present the case of a patient who, during studies for fertility and subsequent pregnancy, showed an altered thyroid profile with elevated levels of free T4 and normal TSH. After ruling out a thyrotropic adenoma and in the absence of clinical symptoms of hyperthyroidism, the possibility of analytical interference in the immunoassays used to measure hormones was investigated. Interferences caused by heterophile antibodies, macro TSH, anti-thyroid antibodies, biotin, and to a lesser extent anti-streptavidin and anti-ruthenium antibodies have been described.

Influence of obesity on atherogenic dyslipidemia in women with polycystic ovary syndrome.

Background: Obesity is known to underlie, at least partially, dyslipidemia in polycystic ovary syndrome (PCOS), but it is unclear whether PCOS status per se increases the risk of alterations of lipoprotein subfractions, which differ in size and atherogenic potential. Our objective was to evaluate whether PCOS influences lipoprotein profile and LDL and HDL subfractions and to study the impact of obesity on these parameters.

Materials And Methods: This was a case-control study conducted in an academic medical centre.

Symptomatic meningioma induced by cross-sex hormone treatment in a male-to-female transsexual.

Transsexualism is defined as a strong conviction of belonging to the opposite sex in individuals without any physical intersex condition. Cross-sex hormone therapy is an important component of medical treatment of transexuals but it is not exempt from adverse effects. We report a case of a meningioma in a male-to-female transsexual patient treated with estrogens and cyproterone acetate for the past 4 years.
