Oral contraceptives and cyproterone acetate in female acne treatment.

The sebaceous gland is a target of androgens, and hormonal influences play an important role in the multifactorial pathogenesis of acne. In both men and women, acne may be related to an excessive hypersensitivity of the sebaceous end organ to androgens. However, in women, the ovarian and adrenal production and the plasma transport of androgens may be implicated, particularly in late-onset or persistent acne or with associated hirsutism. Many reports have shown that females with acne frequently have abnormal levels of circulating androgens. Hormonal treatment is not usually the first line in female acne. But in relation to the possibilities, particularly the tetracyclines, this may be a choice when one prescribes a pill like Dianette to a young woman presenting a mild acne and who requests contraception. However, antiandrogen treatment is sometimes mandatory, especially in resistant acne in adult women and/or in female acne which is resistant or relapsing rapidly after treatment with Roaccutane and which is often related to hyperandrogenism. Finally, in severe prepubertal acne, the possible cause is an adrenal enzymatic block of which the only treatment is hormonal.

Neoadjuvant GnRH-agonist treatment (triptorelin and cyproterone acetate for flare protection) and total prostatectomy.

The effects of 3 months treatment with the GnRH agonist triptorelin as a neoadjuvant to total prostatectomy in 40 men with localized prostatic cancer have been evaluated. The study included 1 patient with a stage T1b tumour, 25 patients with stage T2 tumours and 14 with stage T3 tumours. The patients were examined by digital rectal examination, transrectal ultrasound before and after treatment. Serum testosterone and prostate-specific antigen (PSA) levels were followed. The totally removed prostate gland was step-sectioned at 5-mm intervals and the whole-mount sections were assessed for tumour pathology stage (pT stage). Triptorelin treatment resulted in a significant decrease in total gland and tumour volume and in a reduction in the serum levels of PSA and testosterone. In comparison with the findings from a previous study, in which neoadjuvant treatment was not used, it appears that the proportion of tumours invading the margins of the surgical specimen decreased.
