Hyperlipidemia and presence of thyroid autoantibodies in girls with Turner's syndrome or mosaic variance.

OBJECTIVE: The investigation of differences in the medical status between girls with Turner's syndrome or mosaic variance and healthy girls of the same age. In addition, the existence of differences between those persons with full Turner's syndrome and those with mosaic variance were examined. The influence of the treatment was also of concern because a number of the subjects in the study group were being treated with hormones (estrogen and progestin). Investigation concerned cardiovascular abnormalities, bone age, and lipid and hormonal profiles of the participating persons. PARTICIPANTS: Girls came to the hospital with problems in their menstrual cycles. Genetic control (karyotyping) took place. Each patient with symptoms of Turner's syndrome or mosaic variance was included in the study group. Every third patient with no symptoms of the syndromes and near the same age were included in the control group. METHODS: Stratification was made according to the body mass index of the participating persons. Nonparametric tests were used for the analysis. RESULTS: Differences were detected in the levels of cholesterol, low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and triglycerides, and were increased in the study group. Presence of thyroid autoantibodies, antithyreo-globulin-antibodies (AASTs) and antimicrosomatic antibodies (AASMs), was observed in the study group. In addition, differences were observed in HDL levels between persons with full Turner's syndrome and those with mosaic variance. Finally, significant difference was observed in the level of triglycerides and in the presence of AASTs and AASMs in treated and untreated persons with mosaic variance. CONCLUSIONS: Metabolic, genetic, eating or autoimmune mechanisms are suspected.

Effects of two combined monophasic and triphasic ethinylestradiol/gestodene oral contraceptives on natural inhibitors and other hemostatic variables.

OBJECTIVE: To evaluate the effects of two preparations of combined oral contraceptives (COCs), the monophasic COC containing 30 micrograms ethinylestradiol and 75 micrograms gestodene and the triphasic COC containing 30/40/30 ethinylestradiol and 50/70/100 micrograms gestodene on seven natural inhibitors and hemostatic variables. METHOD: Forty-four healthy young women, randomly allocated into two groups (A and B) received the two preparations of COCs, respectively. The following variables were tested in a basic examination and at 1-, 3- and 6-month intervals to evaluate the role of the above preparations on the hemostatic balance of prothrombin time, fibrinogen, antithrombin III activity, protein C activity, total protein S antigen, plasminogen activity and lupus anticoagulant. RESULTS: Group A women presented shorter prothrombin time at 6 months, an increased fibrinogen level at 3 months, no influence on the anticoagulant factors, antithrombin III, protein C and total protein S and an increased plasminogen activity at the 1st and 3rd months of treatment. On the other hand, group B women presented shorter prothrombin time at 3 months, no increase in fibrinogen, a decrease in antithrombin III activity and total protein S activity at the 6th month, whereas protein C and plasminogen activities were found to be increased at the 3rd and 1st, 3rd and 6th month, respectively. CONCLUSIONS: The study did not find differences between the two treatment groups, for the evaluated parameters. This finding is clearly important in the light of the recent epidemiological reports on third-generation COCs. However, differences were found among the various periods of administration of both COCs.

A flexible protocol for the induction of recipient endometrial cycles in an oocyte donation programme.

Synchronization of the availability of good quality oocytes from donors and adequate endometrial maturation of recipients are very important for the success of an oocyte donation programme. A flexible protocol for the endometrial preparation of recipients is important in timing embryo transfer between days 17 and 19 of the cycle ('window of receptivity'). The purpose of this study was to evaluate the effect of the length of oestradiol administration to recipients on pregnancy outcome. Oestrogen administration was 8 mg/day, but its length varied prospectively from 6 to 27 days, followed by the addition of progesterone (100 mg daily i.m.) for 2-4 days according to the availability of good quality oocytes. Pregnancy outcome was evaluated regardless of age, indication for oocyte donation or number of embryos transferred per patient. The pregnancy rate per cycle was comparable when oestradiol was administered from 6 to 11 days before progesterone addition, while it dropped significantly thereafter. The variation in progesterone administration did not affect pregnancy outcome. These findings provide us with a greater flexibility by allowing us to vary oestradiol administration to recipients from 6 to 11 days prior to progesterone, reducing considerably, therefore, the need to cancel embryo transfer because of oocyte unavailability. Thus we can arrange to transfer embryos between days 17 and 19 of the recipient's cycle so as to obtain the best possible clinical outcome.

High-grade endometrial stromal sarcoma in a 16-year-old girl.

Endometrial stromal sarcoma (ESS) is a rare uterine malignancy with a variety of morphologic characteristics and clinical courses. We describe a case of high-grade malignant ESS in an adolescent girl, arising in a rudimentary uterine horn and presenting symptoms of an acute abdomen. The patient underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy due to a stage IVA high-grade ESS. An adjuvant chemotherapy and radiotherapy treatment was recommended, but 10 days after her discharge the condition of the patient deteriorated, with diffused metastases into the lungs and the abdomen, and finally she succumbed to the disease 1 month after her first admission to the hospital.

Treatment of polycystic ovarian disease during adolescence with ethinylestradiol/cyproterone acetate versus a D-Tr-6-LHRH analog.

OBJECTIVE: This study was undertaken to compare the clinical and endocrinological results of two kinds of treatment on adolescents with polycystic ovarian disease (PCOD). METHOD: Forty-five adolescents with PCOD were randomly allocated into two groups, treated either with ethinylestradiol (EE)/cyproterone acetate (group A) or the GnRH analog D-Tr-6-LHRH (group B). RESULT: No significant changes were detected on the body mass index and waist-hip circumference. A significant improvement of hirsutism was noticed in both groups of patients. A normal menstrual period was recorded in group A adolescents while all group B patients became amenorrheic. A favorable decrease of ovarian volume was detected in both groups. LH/FSH ratio and delta 4-androstenedione serum levels were found significantly reduced in both groups in comparison to pre-treatment levels. The comparison between the two groups, after 6 months, showed significantly lower values of LH/FSH ratio in group B cases. CONCLUSION: Both forms of treatment are safe and effective to a various degree for the management of PCOD adolescents.

Teenage pregnancy: comparison with two groups of older pregnant women.

To evaluate the risk of adolescent pregnancies, we examined three groups of primigravidae in a prospective study from 1987 to 1988. A special protocol for the evaluation and follow-up of adolescent pregnancies was made. The rate of adolescent pregnancies was found to be two times higher between the years 1985 and 1987-1988. The pregnancy complications seen in the adolescent patients were equal to or lower than those found in older women. The cesarean section rate was also found to be lower in adolescent pregnancies. We conclude that sexual education programs are necessary for the reduction of teenage pregnancies and adequate medical prenatal care, as well as psychologic and social support, must be given to avoid both medical and psychologic problems for the sensitive young mother.

Outcome of ovarian response after suppression with a gonadotropin releasing hormone agonist in different chronological periods prior to gonadotropin stimulation for in vitro fertilization.

Gonadotropin-releasing hormone analogues (GnRH-a) are currently used in combination with gonadotropins in ovarian stimulation for in vitro fertilization programs (IVF). The present study aims at evaluating the treatment cycles for IVF for which human menopausal gonadotropin (HMG) was initiated only when pituitary desensitization was confirmed regardless of the time of GnRH-a administration. Two groups of patients were examined. Patients in group A (n = 46) were commenced with HMG treatment on day 15 when E2 level was less than 40 pg/ml. Group B patients (n = 27) comprised the cycle treatments in which E2 levels were greater than 40 pg/ml on day 15. In these cases HMG was first given when E2 levels declined to less than 40 pg/ml. The fertilization rate was similar in both A and B groups, 71.6 and 67.7% respectively. The pregnancy rate per transfer was 27.5 and 34.6% in group A and B respectively. Multiple pregnancies were found at 18.1% in group A versus 44.4% in group B. It is concluded that postponement of HMG administration in patients with high levels of E2 on day 15 after GnRH-a administration seems to offer an improvement in embryo cleavage speed, pregnancy rate and multiple pregnancies.

Prostaglandins: PGF2 alpha, PGE2, 6-keto-PGF1 alpha and TXB2 serum levels in dysmenorrheic adolescents before, during and after treatment with oral contraceptives.

Ten adolescents with primary dysmenorrhea (PD) were treated with the oral contraceptive (OC) Lyndiol 2.5 mg (R) for one cycle. The levels of PGF2 alpha, PGE2 and the metabolites of PGI2 and TXA2: 6-keto-PGF1 alpha and TXB2 were tested by a radioimmunoassay method during the 1st and 23rd day of the pre-treatment cycle (PrTC), the 23rd day of treatment (TC) and the 1st day of the post-treatment cycle (PoTC). The ratios PGF2 alpha/PGE2 and TXB2/6-keto-PGF1 alpha were also tested and compared during the above-mentioned days. Analytical comparison was made, for each Prostaglandin (PG) separately, between the 1st day of the PrTC and PoTC as well as the 23rd day of the PrTC and TC, respectively. All PG levels during TC and PoTC were found significantly lower, compared to those of the PrTC respectively. With regard to the ratios mentioned above, no statistically significant differences were found on the same days and cycles as previously stated. The reduction of the PG levels in PD patients after treatment with oral contraceptives, together with an improvement of the clinical findings of the disease, support the theory that oral contraceptives can be used for the treatment of PD cases, especially for those adolescents who also desire a contraceptive method.
