RESUMO

BACKGROUND: Gynecomastia can be physiological or pathological. A limited study of gynecomastia is recommended during puberty and in the elderly, ages in which gynecomastia is usually considered physiological. Other authors suggest that this condition should be studied when it is painful, rapidly growing, of recent onset, when its diameter is more than 4 cm and when is associated to testicular masses. AIM: To investigate the causes of gynecomastia and to evaluate the above mentioned criteria to exclude pathological conditions. MATERIAL AND METHODS: Prospective study of 117 patients aged 10 to 83 years, consulting for gynecomastia. All were subjected to a standardized study including a clinical examination and measurement of plasma estradiol and testosterone levels. RESULTS: Forty one percent of gynecomastias were considered pathological and the rest, physiological. Among pathological conditions, 18 patients had an endocrine etiology (hypogonadism in ten patients, estrogen secreting tumors in three, hyperestrogenism of unknown etiology in four and peripheral resistance to androgens in one), in 17 it was secondary to medications and in 13 it was secondary to other causes (idiopathic, pesticide exposure, alcoholism, diabetes or re feeding). In 79% of 86 patients of less than 20 years, the condition was physiological and in four of five elderly subjects, it was pathological. Thirty nine percent of pathological gynecomastias lacked the signs and symptoms that according to authors, should prompt a thorough study. CONCLUSIONS: All patients with gynecomastia should be studied with a complete medical history and the measurement of estradiol and testosterone levels. The criteria proposed to conduct minimal studies in gynecomastia, would miss a large volume of pathological conditions.

RESUMO

BACKGROUND: Hypothalamic dysfunction is a cause of menstrual disturbances in women, in whom other diseases have been discarded. This condition is characterized by a failure of the GNRH pulse generation system and is associated to psychological and environmental factors. A lack of ovulatory response to the administration of clomiphene can be a sign of bad prognosis in hypothalamic dysfunction. AIM: To report the natural history of patients with hypothalamic dysfunction and a bad or deficient response to the administration of clomiphene. PATIENTS AND METHODS: Fifty patients with hypothalamic dysfunction, that consulted for menstrual disturbances at the age of 15 to 20 years old, were studied. All received clomiphene and 31 had an ovulatory response, 12 had menses without ovulation and 7 did not menstruate. Of these 19 women eleven were interviewed again about their menstrual and reproductive history, after a lapse of 9 to 17 years of loss from follow up. RESULTS: Eight of the eleven women had stressful events during adolescence (going away from family house in 3, starting university studies in 3, migration out of the natal country in one and non competitive physical activity in one). All restarted their menses and eight with active sexual life had spontaneous pregnancies, giving birth from two to five children. Ovulatory cycles were documented in women without active sexual life. CONCLUSIONS: In teenagers with hypothalamic dysfunction and menstrual disturbances, a deficient or bad response to clomiphene does not necessarily indicate a bad prognosis in terms of menses or fertility.

RESUMO

BACKGROUND: Flutamide is an antiandrogen devoid of other hormonal effects, except for a decrease in the secretion of adrenal androgens such as dehydroepidandrosterone sulphate (DHEA-s) and androstenedione. AIM: To assess the effectiveness of flutamide in the treatment of hirsutism, used as monotherapy or combined with oral contraceptives (OC). PATIENTS AND METHODS: Women with peripheral hirsutism (defined as the presence of normal serum androgen levels and normal ovulatory menstrual cycles) were assigned to receive flutamide alone (500 mg/day) or flutamide plus an OC (ethynylestradiol 0.03 mg and desogestrel 150 microg). Hirsute with hyperandrogenism (polycystic ovary syndrome) were assigned to receive flutamide plus an OC. The degree of hirsutism was assessed using a clinical score (Moncada) at three, six and twelve months of therapy. RESULTS: Twenty five women with peripheral hirsutism received flutamide alone and 18 receive flutamide plus the contraceptive. Eighteen women with polycystic ovary syndrome were studied. At three months, the reduction in hirsutism was 11.2, 15.9 and 24.7% in women with peripheral hirsutism receiving flutamide alone or flutamide plus OC and in hyperandrogenic women receiving flutamide plus OC, respectively. At twelve months, the figures were 57.2, 57.3 and 52.5% respectively. In hyperandrogenic women, at baseline and three months, serum testosterone levels were 0.96 and 0.42 ng/nl and serum DHEA-s levels were 2,980 and 1,490 ng/ml respectively. No collateral effects of treatment or elevations in serum transaminase levels were observed. CONCLUSIONS: Flutamide is effective in the treatment of hirsutism in women with normal or elevated androgen levels. Adding OC did not improve the efficacy of the drug.
