Administration of lithium chloride and copper sulfate to adult monkeys caused marked elevations in plasma vasopressin (AVP) levels without significant increases in plasma oxytocin (OT) levels. Emesis was produced in five of the seven animals given these agents, in support of nausea as the main stimulus to AVP release. A similar pattern of AVP release without OT release was found after administration of cholecystokinin (CCK). Although most monkeys vomited in response to 10 micrograms/kg of CCK, a significant increase in plasma AVP levels also was produced with a dose of 1 microgram/kg, which did not produce emesis in any animal. These findings are in marked contrast with previous results in rats, which indicated that lithium chloride, copper sulfate, and CCK each stimulated OT rather than AVP release. Despite this interspecies difference, the significant neurohypophysial hormone secretion in response to both nausea-producing agents and CCK suggests that AVP secretion in monkeys, similar to OT secretion in rats, might reflect activation of central pathways mediating nausea and/or inhibition of food intake, even when overt illness is not produced.

Appendicitis caused by a misplaced IUD was found in a 29-year-old pregnant woman. The woman had had the device inserted 8 years before. About 5 months after placement and a severe experience of right lower quadrant pain, medical examination revealed that she was pregnant. Abdominal and pelvic X-ray films were thought to be consistent with IUD expulsion, a fairly common occurrence, with an estimated rate of 2-20% within 1 year of placement. Over the next 7 years, the woman continued to experience right lower quadrant pain, but the pain was mild until 20 weeks into her next pregnancy when she was hospitalized with nausea, anorexia, fever, and severe pain. Surgery revealed that her appendix and cecum were bound to an inflamed mass of tissue. During the course of an appendectomy, this tissue mass was found to contain a copper-coated IUD, which was removed by blunt dissection and gentle traction. The IUD had probably partially perforated the uterus on insertion; complete perforation followed in 2-3 months; and copper from the device caused inflammation that eventually involved the appendix. Several months after the appendectomy, it was discovered that the inflammatory mass had been replaced by dense adhesions. This case shows that abdominal and pelvic X-ray examinations may not be sufficient to locate a misplaced IUD in a pregnant woman. If a misplaced device is not clearly visible on X-ray films, further workup may be necessary to avoid the possibility of chronic abdominal pain and complications.

Suprofen (Suprol-Cilag S.p.A.), a prostaglandin synthetase inhibitor, was tested in a double-blind crossover design on 28 women whose IUDs caused them pain or increased menstrual bleeding. The subjects had worn either a Gravigard (18 women) or a Copper T (10) for 6 to 10 months. Each subject was observed for the first month, and took either placebo or Suprofen during the next menses, followed by the alternative for the third cycle. They took 20 mg Suprofen 4 times daily, at the first sign of bleeding and or pain, then 3 times daily thereafter, for the duration of symptoms or up to 7 days. Before treatment, 71% had severe bleeding, 18% had moderate bleeding and 11% had slightly increased bleeding. During Suprofen, 43% obtained a strong decrease in menstrual blood loss, 36% had a moderate decrease and 7% had a slight decrease. Placebo decreased bleeding moderately in 2. Pain was moderate to intense in 26 women and slight or none in 2 before treatment. With Suprofen, pain decreased moderately or greatly in 23 and slightly or not at all in 5 women. Placebo improved pain moderately in 1 subject. Reported side effects of the drug were stomach cramps in 1 and nausea and headaches in 2 women. In this study, when the subjects were categorized by degree of symptoms, the prostaglandin antagonist was more effective in those complaining of more severe bleeding and pain.

Information from animal studies has demonstrated the harmful effects of zinc supplementation on copper transport. Although some studies have been carried out in humans, the effect on humans has not been as well documented as the effect on animals. Forty-seven healthy volunteers (26 women and 21 men) took part in a double-blind cross-over trial which lasted for 12 weeks. The subjects were asked to take 50 mg of elemental zinc (as 220 mg zinc sulphate) or placebo, three times a day for six weeks. Venous blood was collected for the analysis of plasma levels of copper and zinc. Symptoms, which included headaches, abdominal cramps, nausea, loss of appetite and vomiting, were registered from 84% of women and 18% of men. Six female volunteers discontinued the trial; five owing to gastric irritation and one owing to consistent headaches. Plasma zinc levels rose significantly in both men and women, the increase being 36% and 57%, respectively. Plasma copper levels did not change significantly. Our study suggests that the gastric discomfort that is associated with zinc supplementation may be related to body weight as symptoms were reported from the lower-weight volunteers. Our study also shows no detrimental effect of 150 mg of zinc a day on plasma copper levels in healthy volunteers over a period of six weeks.

The plastic intrauterine device is now being used as a carrier to hold the contraceptive agent (copper in this case) in the uterus. The action of copper as a contraceptive agent is thought to be due to an alteration in intrauterine environment thus preventing implantation and causing rapid loss or destruction of the fertilized ova. Studies show that such local use of copper appears to be safe over long-term use, and no changes in cervical cytology or endometrial histology and no evidence of tumor production due to copper have been seen. Presented here is a study of 127 women using a Gravigard (Copper 7) IUD. The patients ranged from 18 to 42 years old, and 33 (26%) were nulliparous. Insertion was easy in 111 (87%), there were minor problems in 10 (8%), and difficulties in 6 (4.7%). The majority of patients had no immediate postinsertion pain or problems, but 11 (9%) did complain of uterine cramps or symptoms of faintness or nausea. 3 patients were lost to follow-up, and the remaining 124 women were followed over a total of 1089 woman-months. 7 patients (5.5%) expelled the Gravigard, 3 (2.4%) became pregnant, and 10 (7.9%) had their IUDs removed for medical reasons.

Postcoital contraceptives, the so-called "morning after pill," are agents used as emergency treatment to prevent pregnancy after unprotected intercourse or contraceptive accidents. In the 1960s and early 1970s high doses of estrogens were used in 5-day courses such as diethylstilbestrol 25-50 mg a day or ethinyl estradiol 0.5-5 mg a day begun within 72 hours after coitus. Although effective, a considerable drawback of the associated nausea and vomiting as well as an increased risk of menstrual disturbance during the treatment cycle. Norgestrel alone in various dosages has been used postcoitally. Quingestanol has been used as a continuing postcoital agent in Latin America but proved unacceptable owing to nausea and irregular bleeding. In China "visiting pills" have been devised containing anordrin. In the West regimens of this sort have been superseded by the Yuzpe treatment of 100 mcg ethinylestradiol and 0.5 mg levonorgestrel initially, repeated after precisely 12 hours. The treatment must be initiated within 72 hours of exposure. Postcoital contraceptives act by combinations of mechanisms--the function of the corpus luteum is disrupted, tubal motility may be affected, and changes in endometrial biochemistry prevent ovoimplantation. In a multicenter trial involving 602 women Yuzpe reported a pregnancy rate of 1.6%. Other workers show comparable figures of 0-3%. The primary side effects of the current hormonal method are nausea, which occurs in 61% of cases, and vomiting, 20% of cases. Both are mild and of short duration. All postcoital methods carry a risk of ectopic pregnancy should the treatment fail. 3 ectopic pregnancies were recorded with diethylstilbestrol and 1 recently with the Yuzpe regimen. There have been no reports of thromboembolic complications. If a hormonal form of postcoital treatment fails, the theoretical possibility of the pregnancy being harmed cannot be ruled out. The patient needs to be counseled about this, and careful records should be kept. Also important is the taking of an accurate menstrual and coital history to exclude exposures earlier in the menstrual cycle. Lippes and coworkers showed the efficacy of copper IUDs as postcoital agents. These can be used up to 5 days from intercourse. An IUD is preferred if hormones are contraindictated, if exposure was more than 72 hours beforehand, if the woman desires the most effective method, and if she wants the IUD for longterm contraception. Postcoital contraception, however defined, raises ethical questions. Postcoital methods could be classed as contraceptive rather than abortive within the maximum period (defined by medical scientific consensus) that may elapse between intercourse and nidation.

Postcoital contraception (PC) has become more effective in recent years and is recommended for women who have had unprotected coitus between the 8th and 17th days of their cycles. Vaginal douche using a spermicide solution is ineffective as it has resulted in a 37% pregnancy rate. Estrogens are far more effective: Diethylstilbestrol (DES), taken in doses of 25-50 mg daily for 5 days, e.g., 10 mg of conjugated estrogens 3 times daily, and 2.5 mg ethinyl estradiol 2 times daily for 5 days 24-72 hours after coitus, has resulted in a .5-1.5% pregnancy rate. Side effects, however, include nausea, vomiting, mastalgia, menorrhagia, extrauterine pregnancy, and adenocarcinoma in daughters of DES-treated women. Gestagens, such as .15-.40 mg of d-norgestrel taken 3 hours after coitus, can be used as a form of planned PC. In an experiment, an estrogen-gestagen preparation consisting of 50 mcg ethinyl estradiol and 500 mcg dl-norgestrel taken 12-72 hours after coitus produced a .9% pregnancy rate in 1300 menstrual cycles with few serious side effects. Copper 7 or copper-T IUDs also prevent the implantation of the fertilized egg, and, when used within 5 days after coitus, produced only 1 pregnancy in 727 cases. The ideal future PC would be a preparation that inhibits either ovulation or nidation and has limited side effects. Among some promising agents are a luteinizing hormone-releasing factor agonist as well as natural and synthetic prostaglandins; however, until their cardiovascular and gastrointestinal side effects have been ameliorated, their routine use is unlikely.

An outbreak of metal fume fever (MFF) among workers involved in cutting brass pipes with electric cutting torches in an enclosed, poorly ventilated steam condenser is described. Twenty-six workers were affected. Symptoms most commonly reported were fever (21), dyspnea (23), chills (21), headache (21), and nausea (19). Fourteen of the workers experienced the symptom of an unusual sweet or metallic taste in the mouth. Clinical signs were limited to wheezing or rales in eight patients. Leukocytosis and an increase in band cell forms were noted in 21 and 20 of 24 workers, respectively. The median time interval between exposure and onset of symptoms was five hours. None of three workers who spent less than one hour in the condenser became ill, whereas 25 of 26 of those who spent more than one hour became ill (p = .001). Five of 12 workers had urine copper levels in excess of 0.05 mg/l. To our knowledge, this is the first reported outbreak of MFF for which urinary copper levels have been measured.

A case of primary ovarian pregnancy involving a Copper 7 (Cu 7) IUD is described, and the pertinent literature is reviewed. A 29-year old white woman, gravida 2, para 2, presented with nausea and fatigue of 1 months' duration and severe bilateral upper abdominal pain with radiation to both shoulders of 1 day's duration. Her menstrual cycles for the previous 4 months had been irregular and her last menstrual period started 35 days prior to admission. She was known to have had a Cu 7 IUD in situ for 26 months. On admission, the patient was in moderate abdominal distress. Direct and rebound tenderness with some voluntary guarding was found in the upper abdomen, with minimal lower abdominal tenderness. Pelvic examination was normal, except for slight tenderness. Pelvic examination was normal, except for slight tenderness in the right adnexal area. No vaginal bleeding was observed. Serum pregnancy test (RIA) was positive. Sonogram of the abdomen showed the IUD in situ, free fluid in the peritoneal cavity, and a mass in the right adnexal area containing fetal parts and a fetal heartbeat. Dilation and curettage after removal of the IUD obtained a minimal amount of tissue. Laparotomy revealed 500-600 ml of blood. The uterus, both fallopian tubes, and the left ovary were normal. A hemorrhagic cystic area at the distal pole of the right ovary was actively bleeding. Wedge resection of the right ovary was performed. The patient recovered well and was discharged from the hospital 4 days after the operation. The hemorrhagic ovarian mass measured 6.0x4.5x3.0 cm. Section demonstrated at 3.0 cm cavity filled with clear fluid. The cavity was lined with a smooth membrane and contained a 1.6 cm embryo. A corpus luteum, 1.5 cm in greatest dimension, was adjacent to the cavity. Microscopic sections showed an edematous stroma and an area of implantation with vascularized chorionic villi adjacent to a corpus luteum. Hemorrhage extended from the area of implantation to the ovarian surface. Sections of the fetus were histologically normal. The diagnosis was ovarian pregnancy. Available data allow an approximation of the proportion of woman years of IUD use that involve the Cu 7 IUD in the US since 1966, which is calculated to be 28%. This calculation agrees with the observed 27% of the cases of ovarian pregnancy with an IUD in situ that involved the Cu 7 IUD reported in the US literature. This comparison suggests that the Cu 7 does not increase or decrease the risk of ovarian pregnancy relative to inert plastic IUDs. Clinicians should be aware of the possibility of ovarian pregnancy in patients who use the IUD.

Uterine perforation is known to be associated with IUD use. Usually the perforation occurs upon insertion, but the IUD can become embedded in the uterus and later be forced through the wall by uterine contractions. On occasion, IUDs have been noted in abdominal viscera, most often the sigmoid colon. Recently, a 20-year-old black woman was encountered whose Copper-7 IUD had perforated her appendix and had caused chronic appendicitis during pregnancy. The woman had had 3 live-born children and 1 spontaneous abortion. The Copper-7 had been inserted 6 months previously without apparent difficulty. At 21 weeks' gestation, the patient developed right lower abdominal pain radiating to the right buttock. She had no other gastrointestinal complaints, was afebrile, and exhibited no abnormal physical findings to explain her symptoms. Urine cultures were negative. 12 weeks later, the patient developed nausea, vomiting, anorexia, and constipation. She was again afebrile. After spontaneous labor at 40 weeks, the patient was delivered of a normal male infant. Following spontaneous expulsion of the placenta, the uterus was manually explored, and no IUD was found. The patient desired postpartum tubal ligation. An x-ray film of the abdomen revealed a Copper-7 IUD in the right lower quadrant at the level of the iliac crest. During the operation, it was noted that the IUD had apparently perforated the uterus 1 centimeter below the right uterotubal junction. The strings were in the myometrium, but the body of the IUD had passed transversely through the lumen of the appendix and remained embedded in it. The IUD may have induced inflammation in an otherwise normal appendix, and this seems most likely particularly because copper-containing IUDs are prone to cause irritation and adhesion formation.
