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.

Correlation between hypo-osmotic swelling test and 'water test' to assess human sperm membrane integrity.

Fifty-nine men who requested vasectomy and 43 infertile patients had a semen analysis performed prior to surgery or during evaluation. A hypo-osmotic swelling test (HOS) and a new 'Water test' were performed simultaneously, in order to assess correlation between these two procedures. Our results showed that values obtained with the 'Water test' were significantly higher than those obtained with the HOS test (P < 0.001). These findings suggest that it is necessary to determine normal values for this new test before introducing it in the routine semen analysis.

Physician-patient communication in the prevention of female reproductive tract infections: some limitations.

The objective of this study was to describe the information that women with tubal infertility recalled having received from physicians when they consulted for a reproductive tract infection (RTI) and the information physicians reported having provided to women consulting for RTIs. Interviews were conducted with 16 women presenting primary tubal infertility selected on the basis of purposeful sampling criteria. Also, 15 physicians working in the public health network in the city of Campinas, Brazil, were selected at random and interviewed. Analysis of the women's statements concerning previous RTI-related medical consultations showed that they did not recall having received any information on either prevention or the impact of RTI on their reproductive future. Analysis of interviews with physicians showed that the information they provided to women consulting for RTIs was incomplete and unclear. The information women recalled having received and that which physicians remembered having provided at the time of treating a patient with RTI was similar. In conclusion, these women lacked adequate or complete information and that it was probably not possible for them to adopt measures to avoid repetition of RTI and minimize risk of tubal infertility.

[Hydatidosis of the humerus complicated with fracture, bacterial infection, fistula, and extraosseous localization].

The clinical case of an apparently healthy 63-year-old man from a rural area, with previous contact with dogs, who had a pathological fracture of the right humerus is presented. Initially he presented slight local pain, and functional discapacity. Eight months later, after a radiological study and surgery (curettage), diagnosis of hydatid disease was made. Later on, after receiving two courses with albendazole, the parent continued in similar conditions for seven years, when his situation became complicated with bacterial, fistula and extraoseous hydatidosis. The humerus was resected and a segmentary prothesis was successfully set.
