Acceptability for the use of postpartum intrauterine contraceptive devices: Assiut experience.
OBJECTIVES: To evaluate the acceptance of postpartum intrauterine contraceptive devices (PPIUCD) among the inhabitants of Assiut governorate, Egypt and to study the factors that influence this acceptance. SUBJECTS AND METHODS: Contraceptive counseling was given to 3,541 clients: 1,880 and 1,661 during the antenatal visits and postpartum hospitalization, respectively. Acceptors during antenatal counseling were to receive IUCDs via postplacental insertion in the case of vaginal delivery or transcesarean insertion in case of abdominal delivery. The clients who refused PPIUCD and chose interval IUCD insertion were referred to the Family Planning Clinic after the end of puerperium. Among postpartum counselees, PPIUCD acceptors received predischarge insertion within 48 h of delivery and the interval IUCD were referred to have IUCD inserted after the end of puerperium. The acceptance rate of both PPIUCD and interval IUCD and the percentage of actual insertions were recorded. The causes of both acceptance and refusal were also recorded. RESULTS: Of the 3,541 clients, 1,024 (28.9%) accepted the use of IUCD after delivery. Acceptance was approximately the same during antenal and postpartum counseling: 26.4 and 31.8%, respectively. Verbal acceptance was higher among women with formal education than among illiterate women. Planning another pregnancy in the near future, preference for another contraceptive method, namely lactational infertility, and complications from previous use of IUCD were the most common reasons for refusing the use of IUCD. Of the 1,024 verbal acceptors, only 243 (23.7%) had the actual insertion of IUCD. CONCLUSION: Both the acceptance and actual insertion of IUCD were low probably because the use of IUCD is a new concept in the community. For these women, the only opportunity to receive information about contraceptives is during childbirth when they are in contact with medical personnel. Hence, it is suggested that family planning should be integrated with maternal and child-care services in order to effectively promote the use of contraceptive devices in these women who otherwise would not seek the use of such a device.

Reduced menstrual blood loss by release of an antifibrinolytic agent from intrauterine contraceptive devices.
Lippes Loop and Multiload intrauterine contraceptive devices (IUDs) were fitted with silicone rubber sleeves which either did not contain any compound (blank) or contained the antifibrinolytic agent, epsilon-aminocaproic acid (EACA. In vitro measurements showed that the antifibrinolytic agent was released from the sleeves for a period of 20 days. After insertion into women, the blank Lippes Loop IUDs and Multiload IUDs as well as copper-containing Multiload IUDs caused a significant increase in blood loss beginning with the first menstrual cycle after insertion. The enhanced blood loss was generally retained during subsequent menstrual cycles. By contrast, the menstrual blood loss induced by IUDs containing EACA sleeves was not significantly greater during the first menstrual cycle after insertion that the preinsertion levels. When no more EACA was released, menstrual blood loss increased to approximately the same level as that observed with the blank and copper IUDs. Thus, release of EACA from an IUD retains menstrual blood loss at approximately physiologic levels. These results encourage the development of IUDs that are capable of releasing antifirbrinolytic agents over a long period so that the antimenorrhagic effect is maintained.

Molding of the uterus following intrauterine contraceptive device removal: documentation by hysterosalpingography.
Intrauterine contraceptive devices (IUDs) distort the uterine cavity. We report 2 cases of endometrial molding demonstrated by hysterosalpingography (HSG) following removal of an IUD. Other processes may cause filling defects in the uterine cavity including inflammatory synechiae (Asherman's syndrome), tuberculosis, endometrial hyperplasia, and polyps. Whenever filling defects are seen, the history of IUD usage should be determined.

Isolation and identification of actinomycetes from women using intrauterine contraceptive devices.
Of 259 women using intrauterine contraceptive devices 80 (31%) had visible actinomyces-like filaments in their cervical smears. Actinomycetes were cultured from a total of 31 women. Suspicious cultures were identified with the aid of a commercially available kit in conjunction with a computer data base. Culture was found to be less sensitive than microscopical examination of cervical smears in detecting actinomycetes in these women.

Scanning electron microscopy as an analytical tool for the study of calcified intrauterine contraceptive devices.
Within the endometrial cavity intrauterine contraceptive devices (IUDs) become encrusted with cellular, acellular, and fibrillar substances. Scanning electron microscopy was used to study the crust. Cellular material consisted mainly of blood cells and various types of bacteria. The fibrillar material appeared to be fibrin which was omnipresent in the crust and formed a thin layer immediately over the IUD surface. X-ray microanalysis of the acellular component of the crust revealed the presence of calcium. No other major peaks were identified. Near the IUD surface characteristic calcium phosphate crystals were present. Their microanalysis showed peaks for calcium and phosphorus. X-ray diffraction of the crust however, showed it to contain only calcite. It is through the use of scanning electron microscopy that calcium phosphate has been detected in the IUD crust and a fibrillar layer has been visualized on the IUD surface. This study further demonstrates the effectiveness of SEM analytical techniques in the area of biomedical research.

Scanning and transmission electron microscopy of material adherent to intrauterine contraceptive devices.
The material adherent to intrauterine contraceptive devices (IUCDs) has been studied by transmission and by scanning microscopy coupled with X-ray microprobe analysis. Inert (Lippes Loop D, Saf-T-Coil and Dalkon shield) and medicated (Copper 7 and Progestasert) IUCDs were removed for examination from uteri immediately after hysterectomy. The cellular material identified on the surface of all inert IUCDs consisted mainly of macrophages with some polymorphonuclear leucocytes, erythrocytes, a few platelets and fibrin fibres. Polymorphonuclear leucocytes were the principle cells on the copper devices. Larger numbers of cells were evident on the inert arms than on the active part of the Progestasert device. All the devices examined exhibited varying amounts of surface calcium deposition. The IUCDs which had been in utero for longer periods showed the greatest amount of calcium deposition. Although a less rapid calcium deposition appeared to occur on the Progestasert device, this deposition may influence the release of medications from IUCDs which are retained in utero for longer periods than one year.

[Migration of an intrauterine contraceptive device into the urinary bladder: report of one case].
OBJECTIVES: To report one case of uterine perforation and migration into the urinary bladder of an intrauterine contraceptive device. METHODS/RESULTS: 42-year-old female patient who presents with lower urinary tract irritative syndrome in association to recurrent urinary tract infection. Ultrasound revealed apart of an intrauterine device inside the bladder, device which was inserted years before and was supposed to have come out spontaneously. Urethrocystoscopy with extraction of the intravesical segment and hysteroscopy with extraction of the intrauterine segment were carried out. CONCLUSIONS: The postoperative period was satisfactory and patient is currently asymptomatic. Radiological or ultrasound controls should be performed in the follow-up of patients with intrauterine contraceptive devices. The inability to locate an intrauterine contraceptive device in a patient who did not realize it coming out should be considered an uterine perforation until proved otherwise.

Long-term use of intrauterine contraceptive devices in a private practice.
Clinical experience with 1504 insertions of intrauterine contraceptive devices (Lippes Loop, Dalkon Shield, Cu-7) in a private practice is evaluated. Expulsion rates and removal rates for bleeding and/or pain and personal reasons differed for the three types of devices. Pregnancy rates associated with use of the three types of devices were similar. Pelvic inflammatory disease rates were similar for Dalkon Shield and Cu-7 users but were higher than the rate for Lippes Loop users. Use of intrauterine contraceptive devices did not appear to compromise future fertility based on the experience of women who had the devices removed. The study shows that long-term IUD use (up to 5 years) provides a safe and effective method of contraception.

Intravesical stone formation on intrauterine contraceptive device.
Since more than 30 years, intrauterine contraceptive devices (IUCD) have been used for a contraceptive opportunity. Although they are termed to be a safe and effective method for contraception, they also have some type of complications and uterine perforation, septic abortion, pelvic abscess are the serious complications of these devices. The incidence of uterine perforation is very low, but in the literature nearly 100 cases were reported about the extra uterine localization of IUCD. Migration may occur to the adjacent organs. We here in describe a case of a 31 year-old woman who had an IUCD with stone formation in the bladder. In the literature all of the cases were reported as IUCD migration, but although it seems technically impossible, IUCD placement into the bladder should also be considered in misplaced IUCDs.

Mechanism of action of intrauterine contraceptive devices and its relation to informed consent.
The purposes of this review are to evaluate the available evidence for the mechanisms of action of copper-impregnated intrauterine contraceptive devices and to describe the informed consent consequences of those mechanisms. The medical literature was reviewed with the use of the Bioethics and Medline databases (1966 to present). Reports that supported or refuted the two major postulated mechanisms (interference with implantation of the fertilized ovum or spermicidal inhibition of fertilization) were assessed for their relative strength and support for the exclusivity of one or the other mechanism. The analysis of the evidence strongly suggests that the contraceptive effectiveness of intrauterine contraceptive devices is achieved by both a prefertilization spermicidal action and a postfertilization inhibition of uterine implantation. Patient informed consent for intrauterine contraceptive device insertion should include a discussion of these mechanisms of actions so as to avoid their use in patients with moral objections to postfertilization contraception.

Safety of intrauterine contraceptive devices during MR imaging.
Three intrauterine contraceptive devices (IUD) were examined in an experimental in vitro setup to test their MR compatibility: Multiload CU375. Nova T (containing copper and silver), and Gyne T. The devices were fixed in a polyacrylamide gel and exposed to the magnetic field and the radiofrequency (RF) of standard MR sequences (spin-echo, turbo-spin-echo, turboFLASH, and magnetization transfer prepared FLASH). The RF power of a turbo-spin-echo sequence was increased by a factor of 5. Temperatures of the IUDs and the gel were measured during the MR examination. No deflection of the IUDs exposed to the magnetic field of 1.5 Tesla was detected. Under normal imaging conditions no temperature increase could be observed. Using an increased RF power, a maximal temperature rise of 0.4 degree C per examination was seen. No differences between the gel and the IUDs were observed, indicating that there is no specific heating of the tested IUDs.

Analysis of surface deposits on intrauterine contraceptive devices.
Surface deposits on stainless steel contraceptive devices removed from the uterus after varying periods of insertion were examined and analyzed by means of scanning electron microscopy (SEM), X-ray energy dispersive analysis (XEDA), Augar electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and atomic absorption spectrophotometry for microquantitative analysis. The data obtained were compared with the data for copper-bearing IUDs (TCu200) obtained by the same method. The wire coils of stainless steel IUDs which had been in situ for 5 years showed no obvious changes, but copper wire coils showed varying degrees of erosion after the same period of time. Analysis clearly showed that the wire coils of both types of IUD were encrusted with deposits. Deposition began earlier on copper-bearing IUDs than on stainless steel IUDs (27 days and 3 months after insertion, respectively). This process began earlier than has previously been reported in the literature. The amount of deposit increased with duration of insertion, but there were large individual variations. The microanalysis showed that the principal component of the deposit on both types of IUD was calcium, which was present in the crystal form of calcium carbonate. The substances attaching to the crystals were similar to the nitrogenous organic compounds. We suggest that the mechanism regulating the deposited formation may be similar to that of calculus. The influence of these deposits on complications relating to IUD insertion, such as uterine bleeding and accidental pregnancy, is briefly discussed in this article. The subject should be studied in greater detail.

Copper intrauterine contraceptive devices in adolescent nulliparae.
Copper intrauterine contraceptive devices (IUCDs) were used in 243 young nulligravidae attending a gynaecological clinic for schoolgirls in Uppsala between March 1973 and June 1975; 226 of these girls (93%) were seen again during December 1975 making a total of 3138 months of observation. At the time of follow up, 126 patients (55.8%) still had the IUCD in situ; 20% had expelled the IUCD and in another 24.2% the IUCD had been removed because of bleeding and/or pain or because of suspected pelvic inflammatory disease (7 patients). Twelve of the girls conceived during the period of observation making the Pearl index 4.6; nine of the conceptions occurred within nine months of the insertion of the IUCD. Unlike others we do not advocate the use of the IUCD for young nulligravidae.

Removal of intra-abdominal intrauterine contraceptive devices.
Thirteen cases of misplaced intrauterine contraceptive devices removed from the abdominal cavity over a two year period at the Chelsea Hospital for Women, are reviewed. Five of the six plastic devices were removable laparoscopically but all the copper containing devices required a laparotomy for removal because of an omental or peritoneal reaction.

Laparoscopic removal of an intraperitoneal translocated intrauterine contraceptive device.
The use of an intrauterine contraceptive device (IUD) is often accompanied by various complications, the perforation of the uterus constituting the most dangerous. Here we report the case of a patient who complained of abdominal pains. She had had an IUD inserted 15 months previously. Three months later, as she could no longer see the IUD strings at the external os of the cervix, she underwent pelvic ultrasonography, which did not show the IUD in the uterine cavity. A diagnosis of expulsion of the IUD was made. A few months later, the patient accidentally became pregnant, and decided to have an abortion. From that time on, she started to complain of the above-mentioned symptoms. She had an abdominal X-ray which revealed the IUD in the abdominal cavity. She then underwent a laparoscopic removal of the translocated IUD.
