Management of the lost intrauterine contraceptive device

In order to establish that a lost IUD is within the uterine cavity, a special hook-type instrument was designed to enable removal of the device when it was located within the uterine cavity. This instrument was 100% successful in removing 17 IUDs with no visivle tails and which were within the uterine cavity. Failure to remove a lost IUD by this method in 4 other patients indicated the device's absence from the uterine cavity. The technic is simple and has not been associated with any patient discomfort or complications. X-ray procedures or operative manipulations may thereby be avoided. Therefore, when the tail of an IUD is no longer visible, immediate removal can be attempted in order to establish the intrauterine location of the device. If the patient wishes to continue using this form of contraception, a new device should be inserted.     

Loss of radiopacity may impede localization of intrauterine contraceptive device

While ultrasound is the primary modality for localization of an intrauterine contraceptive device, plain films are often employed if the ultrasound examination is negative. A case is reported in which loss of radiopacity hampered identification of an intrauterine device.     

The copper-7 intrauterine contraceptive device: 5-year evaluation

Over a 5-year period a family practitioner inserted copper-7 (Cu-7 intrauterine contraceptive devices (IUDs) in 134 women. The rates of continued use after 2 years, 53.0% for the women's first IUD and 63.9% for all their IUDs, and of accidental pregnancy, 2.4%, are comparable to those in the literature. However, in this series the rate of expulsion was 0.8%, much lower than that in the literature. Fertility did not appear to be reduced in women who planned to have pregnancies after the device was removed. A carefully scrutinized technique of insertion and conscientious follow-up make the Cu-7 IUD an acceptable form of contraception for many patients in a family practice.     

Clinical experience with the copper-7 intrauterine contraceptive device. A preliminary report

There have been 203 copper-7 IUD insertions performed in 199 women. The data from 2,230 woman-months of use have been analyzed and compared with other published reports. The copper-7 IUD was an acceptable contraceptive method in regard to effectiveness, continuation, and lack of serious complications.     

Abdominal actinomycosis associated with intrauterine device: CT features

Abdominal actinomycosis is a severe and progressive peritoneal infection, due to an anerobic gram-positive bacterium, Actinomyces israelii. The presence of a long-standing intrauterine device (IUD) is a well-known risk factor in young women. We report two cases of pelviperitoneal actinomycosis appearing in two young women with acute low abdominal pain. Abdominal CT demonstrated multiple solid or encapsulated peritoneal masses with marked contrast enhancement and infiltration of the adjacent mesenteric fat. Laparoscopy confirmed the presence of intraperitoneal abscesses which contained Actinomyces israelii. High doses of amoxicillin and clavulanic acid (Augmentine) were given and following CT scan after 2 and 6 weeks showed a slow, but complete, resolution of the lesions. Although the radiologic presentation of actinomycosis is nonspecific, the diagnosis should be raised in the presence of pseudotumoral mesenteric infiltration, particularly in young women with an IUD. Abdominal CT is a useful method for diagnosis and for follow-up.     

Factors affecting intrauterine contraceptive device performance. I. Endometrial cavity length

The relationship of endometrial cavity length to intrauterine contraceptive device (IUD) performance was evaluated in 319 patients wearing three types of devices. The rate of events, defined as pregnancy, expulsion, or medical removal, increased significantly when the length of the IUD was equal to, exceeded, or was shorter by two or more centimeters than the length of the endometrial cavity. Total uterine length was found to be a less accurate prognostic indicator of IUD performance than endometrial cavity length alone.     

Ectopic pregnancy associated with the intrauterine device: a study of seventy cases

Seventy cases of ectopic pregnancy associated with an IUD comprised 10% of all ectopics in a 9 year period. This increased to 15% in the last 19 months as more IUD's were in use. In two thirds of the ectopics the IUD had been in situ more than 1 year. Unusual bleeding and cramping attributed to the IUD obscured the diagnosis and resulted in removal or replacement of the IUD in over one half the cases 1 to 8 weeks before surgery. The episodic nature of the abdominal hemorrhage in two thirds of all ectopics resulted in surgery on day 44 average gestational age. The IUD is probably not causal in ectopic pregnancy but does not protect the predisposed patient from ectopic pregnancy which should be suspected in any patient with an IUD who has irregular bleeding and abdominal pain.     

Ileal penetration by a Multiload-Cu 375 intrauterine contraceptive device. A case report with review of the literature

A case of a 28-year-old gravida 3 para 2 woman with an ileal penetration by an intrauterine device (IUD) is reported. Four weeks following insertion of a Multiload-Cu 375, the woman underwent laparotomy due to persistent vague abdominal pain and translocation of the IUD. The device had perforated the fundal uterine wall and the two flexible side arms and the copper-bearing rod had completely eroded into the wall of the ileum with only the strings protruding outside the small bowel mesentery. Resection of an ileal segment with end-to-end anastomosis was performed. The woman made an uneventful recovery. It appears that a translocated Multiload-Cu 375 IUD body can penetrate and be entirely embedded within the bowel wall as early as 4 weeks following translocation. This report documents the shortest interval between insertion and proven bowel injury by an IUD.     

Fetal and maternal endocrine responses to experimental intrauterine infection in rhesus monkeys

OBJECTIVE: Our purpose was to describe the temporal and quantitative relationships among intrauterine infection, fetal-placental steroid biosynthesis, and preterm labor in a nonhuman primate model. STUDY DESIGN: On approximately day 130 of gestation (term 167 days) chronically instrumented rhesus monkeys (Macaca mulatta) were infected with 10(6) colony-forming units of group B streptococci either by intraamniotic (n = 4) or choriodecidual (n = 2) inoculation. As controls, four additionally chronically instrumented noninfected monkeys were followed up to spontaneous parturition. Amniotic fluid and maternal and fetal arterial blood were serially sampled in all monkeys (both before and after infection) for progesterone, estrone, estradiol, dehydroepiandrosterone, dehydroepiandrosterone sulfate, androstenedione, and cortisol by specific radioimmunoassays, and uterine activity was continuously recorded. RESULTS: Spontaneous parturition was preceded by gradual and significant increases in the plasma concentrations of fetal dehydroepiandrosterone, dehydroepiandrosterone sulfate, and androstenedione and fetal and maternal levels of estrone, estradiol, and progesterone but not by changes in cortisol. In contrast, infection-associated parturition (either intraamniotic or choriodecidual) was characterized by abrupt increases in fetal dehydroepiandrosterone, dehydroepiandrosterone sulfate, androstenedione, progesterone, and cortisol but not by increases in maternal or fetal estrone or estradiol. Infection-associated steroid changes occurred concurrently with or after increases in uterine activity. CONCLUSION: Infection-associated preterm parturition is associated with dramatic increases in fetal adrenal steroid biosynthesis but not by corresponding increases in placental estrogen biosynthesis. This suggests that fetal stress in accompanied by placental dysfunction and that infection-associated parturition is not dependent on the increased estrogen biosynthesis observed in spontaneous parturition.     

Hepatic adenoma associated with oral contraceptive use: an unusual clinical presentation

A young woman who had taken contraceptive steroids for many years had the acute onset of abdominal pain because of central necrosis and hemorrhage into a hepatic adenoma. She had multiple lesions confined to one lobe of the liver. Persistent pyrexia and leukocytosis were also prominent clinical findings. She has had no evidence of recurrence of this problem during the seven years following right hepatic lobectomy. A review of the anabolic and contraceptive steroid-associated hepatic neoplasms is presented with comments directed toward the recognition of the critical clinical sequelae that can befall the patient with hepatic adenoma. Although all the patients in the steroid-treated group have tumors with benign and striking histologic similarity, microscopic evidence of malignant invasion of surrounding tissue is occassionally noted.     

Mechanism of action of the intrauterine contraceptive device: evidence for a specific biochemical deficiency in the endometrium

The precise mechanism of action of the intrauterine contraceptive device (IUCD) is uncertain. In this study we compared the circulating concentrations of a specific endometrial protein, placental protein 14 (PP14), in 62 women with an IUCD and 16 controls. The concentrations of PP14 were substantially lower in IUCD users. There was no difference in the concentrations of another and less specific endometrial protein, insulin-like growth factor binding protein-1 (IGFBP-1). There was no difference in PP14 concentrations between those women with and without intermenstrual bleeding. We conclude that the reduced concentrations of PP14 in IUCD users reflect defective endometrial function in these women, probably related to the contraceptive effect. We propose that the measurement of PP14 might be a means of comparing the efficiency of different devices.     

Fetal heart rate patterns in patients with intrauterine growth retardation

Electron microscopy of the absorption surface of the jejunal epithelium of the howler monkey Alouatta caraya showed the presence of core filaments implanted at the level of the terminal web in the microvilli. These microvilli are 5 to 7 mum long and up to 5 mum thick, their extraordinary development is attributed to a conditioned adaptation of the species to its feeding habits and nature of absorption.     

The diagnosis of brain lesions in newborns with an intrauterine herpetic infection

Enzyme immunoassay and DNA hybridization technique were used to diagnose herpetic infection. Blood and liquor antiherpetic antibodies were detected, with anticytomegalovirus antibodies used as reference ones. Intrauterine herpetic infection was detected in 61.5% of 91 risk group newborns. We should like to emphasize that two laboratory tests should be used to diagnose an intrauterine herpetic infection in newborns. Detection of antiviral antibodies in the CSF is a valuable method for the diagnosis and differentiation of brain involvement in intrauterine herpetic infection.     

Safety of intrauterine contraceptive devices during MR imaging

OBJECTIVE: We report a case of candidiasis of the upper urinary tract that presented as acute renal failure associated with septic syndrome. The patient initially required hemodialysis. Right hydronephrosis and perirenal collection were observed on ultrasound examination. METHODS: A percutaneous nephrostomy was performed. Nephrostomy urine cytology and cultures were positive for Candida tropicalis. An anterograde pyelography showed a 'fungus ball' in the urinary tract. RESULTS: Therapy with oral fluconazole and percutaneous amphotericin B achieved excellent results. CONCLUSIONS: Candidiasic urinary infection of the upper urinary tract often produces obstructive uropathy requiring percutaneous nephrostomy, which can also be used to instill amphotericin B. Combination therapy with amphotericin B and fluconazole can achieve excellent results.     

Intrapericardial foregut cyst associated with intrauterine death

Intrapericardial developmental foregut cysts are rare and are most frequently incidental findings at necropsy in adults. A 29 year old Asian woman delivered a 24 week stillborn fetus seven days after diagnosis of intrauterine death caused by rupture of a foregut cyst. Multiple cysts occupied the wall of the right atrium and its rupture caused haemopericardium and cardiac tamponade.     

Appropriate use of the intrauterine device

The intrauterine device, a common form of birth control in the early 1970s, is now avoided by American physicians and women because of concern about complications. This concern is largely the result of the problems reported with use of an intrauterine device that is no longer manufactured. More recent intrauterine devices have an improved design, and reevaluation has shown them to be a safe, efficacious and cost-effective form of birth control. Careful patient selection and preinsertion counseling are crucial to success with the device. Recent studies conclude that the intrauterine device poses no increased risk of pelvic inflammatory disease or infertility when used by appropriately selected patients.     

Pregnancy in the presence of an intrauterine contraceptive loop (IUD) in the uterine cavity

One of the most important questions, raised after the occurrence of intrauterine contraceptive loop, is the problem about the fate of pregnancy. The authors describe the attitude of the obstetrician toward pregnancy and a loop during the 3 trimesters of gestation. They give some practical important rules for roentgenological control and diagnosis and for treatment of women. To illustrate the seriousness of the problems which could arise, the authors present 2 cases--1 with interrupted pregnancy and another with full term pregnancy and normal delivery. Typical roentgenological pictures illustrate the difficulties which the physician should overcome frequently in order to establish the correct diagnosis and eventually to begin the proper treatment.
