Long-term evaluation of the clinical performance of the TCu200B and the TCu380A in Campinas, Brazil.

The clinical performance of the TCu200B and TCu380A was evaluated by life table analysis in a cohort of women who wore an IUD from July 1979 to July 1982. This paper presents the results up to five years of use. No significant differences in age and parity were found between the users in the two groups. Overall performance was very good with both models. The cumulative continuation rate was 83.6, 60.9 and 46.1 at one, three and five years with the TCu200 and 84.0, 64.7 and 49.3 with the TCu380A in the same periods. Differences between both IUDs were not significant. The pregnancy rate was lower with the TCu380A and reached statistical significance from the fourth year on. The authors conclude that both IUDs presented very good performance, the TCu380A being more effective, the only significant difference observed.

Evaluation of the performance of the copper T380A IUD up to ten years. Is this IUD a reversible but potentially permanent method?

The clinical experience of a cohort of 340 women using a TCu380A IUD for up to 10 years at the Family Planning Clinic of the State University of Campinas, Brazil was evaluated by life-table analysis. Removals for medical reasons were more frequent during the first year of use, while from the third year on, removals for personal reasons were more frequent. Expulsions were concentrated in the first two years of use, and none were detected after the fourth. Gross pregnancy rate accumulated to 2.0, 2.8 and 5.3 and continuation rate was 64.2, 43.4 and 27.8 per 100 women at three, six and ten years of use, respectively. The effectiveness of the device did not decrease significantly after the eighth year of use and it could be considered a reversible but potentially permanent method.

Comparison of local signs and symptoms after the insertion of Norplant implants with and without a scalpel.

The study compares NORPLANT subdermal implants acceptors enrolled randomly for two different insertion procedures. One group (420 women) received the implants with the use of a scalpel according to the manufacturer's instructions. The other group (423 women) received the implant without an incision, directly through a sharpened trocar. The local signs and symptoms were observed at 7 and 30 days after insertion. Pain, tenderness, edema/swelling, ecchymosis and defective scar were considered. Complication rates were low and no significant differences were found between the two procedures. Based on the data of this study, we recommend inserting NORPLANT implants without the use of a scalpel.

Menstrual pattern and ovarian function in women with hyperprolactinemia.

Prolactin (PRL) and progesterone were systematically measured in all women presenting with amenorrhea, oligomenorrhea or galactorrhea at the Infertility Clinic of the Department of Obstetrics and Gynecology, State University of Campinas, Brazil, during a period of 34 months. The same hormonal assays were done to all infertile patients presenting for the first time during the last 6 months of the same period, for a total of 190 subjects. Fifty-five patients with amenorrhea, 38 with oligomenorrhea and 97 with normal cycles, 20 of whom had galactorrhea, were included in the study. Fifty-five percent of amenorrheic patients, 37% of oligomenorrheic and 9% of those with normal menses had elevated PRL. The mean PRL was higher the greater the menstrual disturbance but was not influenced by presence or absence of galactorrhea. Short luteal phase was the ovarian function condition most frequently associated with high PRL among women with normal menses.
