13 hospitals in the Guangdong province fitted 4321 women with a flower design IUD fabricated of high pressure polyethylene impregnated with 30% barium sulfate. The upper part of the device has 3 laterally flexible petals that overlap to adapt to the shape and size of the uterus. The lower part is narrow, where the petals are bound. Insertion can be done by paramedical personnel. An inserter is used. Expulsion rate in this series was 5.9%; 30% were expelled during menstruation and 48.2% were expelled during the first year. 125 of 4321 users became pregnant (2.9% rate). Most cases were pregnancies with device in situ. Most removals were necessitated by bleeding, pain, or leukorrhea. Removal rate was 7.5%. Severe symptoms which appear right after insertion tended to dissipate with time. Side effects noted were profuse menstrual bleeding, backache, abdominal pain, and increased leukorrhea. Change in uterine bleeding pattern was the most frequent complaint. 338 endometrial specimens were obtained for morphological examination, and changes were slight; only 3 cases showed signs of endometriosis. 209 of 221 IUDs examined after 3-9 years of use were still in good shape. 12 were cracked.

The radiographic appearance of ring-like densities in the true pelvis, when associated with pain, may suggest the presence of ureteral calculi or phleboliths, leading to either misdiagnosis or oversight by the physician who is unfamiliar with the appearance of fallopian tube occlusion rings. Tubal ligation of any type may be associated with intermittent lower abdominal pain. The recognition of fallopian tube occlusion rings may result in an accurate diagnosis of the cause of pelvic pain. 2 figures illustrate the appearance of the rings. Silicone rubber rings may be placed over a knuckle of the midfallopian tube as a highly reliable sterilization technique. The rings themselves are composed of barium sulfate-impregnated dimethypolysiloxane, an inert siliconized synthetic rubber. They have an outside diameter of 3.6 mm, an inner diameter of 1.0 mm, and are 2.2 mm thick. Foreshortening, obliquity, and film magnification may result in minor variations in dimensions. A review of more than 4000 procedures during the early experience with occlusion ring sterilization, the number of pregnancies was less than 1 in 600. The pregnancies usually occurred because conception occurred before the procedure or because of misplacement of the rings. Lower abdominal pain and bleeding continue as the most serious postoperative complications. Within the true pelvis the fallopian tube occlusion rings may lie close to the course of the pelvic ureters, simulating ureteral calculi. Ureteral calculi rarely have central lucencies. When seen at an angle or on end no central lucency may be visible. The rings may be overlooked amidst pelvic phleboliths. Arterial calcifications are curvilinear yet usually form an incomplete circle, and they rarely appear as sharply marginated as fallopian tube occlusion rings.

Intravenous injection of crude marijuana extract led to development of an acute illness with multisystem involvement. Gastrointestinal manifestations consisted of severe vomiting, diarrhea, and crampy abdominal pain. Hypotension, tachycardia, and peripheral vasodilation constituted the main cardiovascular manifestations of the disease. Moderate azotemia and oliguria, presumed to be of prerenal origin, were present and rapidly resolved with administration of intravenous fluids. Hematologic manifestations consisted of leukocytosis with a left shift, thrombocytopenia, prolonged partial thromboplastin time, increased fibrin degradation products, and positive protamine sulfate test. The observed coagulation abnormalities may suggest intravascular coagulation. C3, C4, and total hemolytic complement were reduced, suggesting possible activation of the complement system. Hyperventilation, hypoxemia, pulmonary edema, obstructive, and restrictive pulmonary function abnormalities and bilateral pleural effusions highlighted the pulmonary manifestations of the disease. Rhadbomyolysis and mild hepatic function abnormalities were also present. All observed abnormalities reversed in a few days with no significant sequelae.

Although allergic reactions to copper are rare, skin disorders may appear or worsen during the perimenstrual period. This paper presents the case of a 41-year-old user of a copper-containing IUD who presented with a history of recurrent, self-healing skin eruption associated with abdominal pain. The eruption followed a cyclical pattern, appearing 3-7 days before menses and improving spontaneously with the onset of bleeding. Patch testing revealed a positive reaction to copper sulfate and nickel sulfate. After the IUD was removed, abdominal symptoms subsided at the next cycle and progressive resolution of the dermatitis was observed.

The objective of this study was to determine the acute gastrointestinal effects caused by the consumption of drinking water containing graded levels of added copper. Sixty healthy, adult women were randomly assigned to receive copper [Cu(II)] at four concentrations in their drinking water following a Latin-square design. Each group (n = 15) received tap water with no added copper, 1, 3, and 5 mg Cu/l of added copper sulfate for a 2-week study period, followed by 1 week of standard tap water. The subjects recorded their water consumption and gastrointestinal symptoms daily on a special form. The average daily consumption of water was 1.64 liters per subject, regardless of the amount of copper added. Final serum copper, ceruloplasmin, and liver enzymes were measured in all subjects and were not different from baseline concentrations. Twenty-one subjects (35%) recorded gastrointestinal disturbances sometime during the study, 9 had diarrhea, some with abdominal pain and vomiting, and 12 subjects presented abdominal pain, nausea, or vomiting. There was no association between copper levels in drinking water and diarrhea. However, nausea, abdominal pain, or vomiting were significantly related to copper concentrations in water. The recorded incidence rate of these symptoms was 5, 2, 17, and 15% while ingesting water with 0, 1, 3, and 5 mg Cu/l, respectively (overall [chi]2 = 11.3, p<0.01; Cu [less than/equal to]1 mg/l versus Cu [Greater than/equal to]3 mg/l, [chi]2, p<0.01). When subjects interrupted their consumption of drinking water with added copper, most symptoms disappeared. We conclude that under the conditions of the study, there was no association between aggregate copper in drinking water within the range of 0-5 mg/l and diarrhea, but a [Greater than/equal to]3 mg Cu/l level of ionized copper was associated with nausea, abdominal pain, or vomiting. Additional studies with sufficient numbers of subjects are needed to define thresholds for specific gastrointestinal symptoms with precision and to extrapolate these results to the population at large.

Cyclic vomiting syndrome is characterized by sudden episodes of vomiting and abdominal pain. It occurs primarily in children, is exacerbated by stress, and is often considered a migraine equivalent. Migraines have been linked to mast cells, which are often found close to neurons where they are activated by neuropeptides. We investigated the ultrastructural appearance of rat ileal brush border and mast cells following acute stress by immobilization. The effect of sulfated proteoglycans heparin and chondroitin sulfate was also tested on mast cell histamine secretion. Ileal brush border appeared intact in control animals, but was shorter and exhibited intercellular gaps after 30 min of acute immobilization stress. Mast cell activation in control rats was minimal, while stress induced obvious signs of activation as judged from disappearance of secretory granule electron dense contents. However, these intragranular changes were not accompanied by typical degranulation through exocytosis. Treatment of purified homogeneic rat peritoneal mast cells with 10(-4) M heparin or chondroitin sulfate 30 min prior to stimulation with 0.5 microg/ml compound 48/80 decreased histamine release by over 70% and 50% (P < 0.05), respectively. These results suggest the possible usefulness of chondroitin sulfate in conditions such as cyclic vomiting syndrome.

The pharmacokinetic profiles, safety, and tolerability of continuous subcutaneous infusion with a novel drug deliver system (the MEDIPAD system) was compared to a standard infusion pump (the CADD-Micro) and to controlled-release tablets (MS Contin) for the administration of morphine sulfate. This was a single-center, open-label, three-treatment study conducted in 24 male and female healthy volunteers. The mean age was 40.6 yr (SD = +/- 12.27). A three treatment design was chosen to compare differences between modes of administration within each subject to minimize the impact of intersubject variability: Treatment A was a continuous 48-hr subcutaneous infusion of morphine sulfate (165.6 mg at a rate of 3. 45 mg/hr) with the MEDIPAD system attached to the chest, Treatment B was a series of four oral doses of morphine sulfate (120 mg each) at 12-hr intervals, and Treatment C was a continuous 48-hr subcutaneous infusion of morphine sulfate (163.2 mg at a rate of 3.40 mg/hr) with the CADD-Micro device attached to the chest. Subjects began treatment after eligibility was established and informed consent was obtained. The primary pharmacokinetic parameters (AUC, C(max)) for the two devices were similar; 90% confidence intervals showed that the MEDIPAD system was bioequivalent to the CADD-Micro in terms of both rate and extent of morphine absorption. The mean morphine plasma concentration versus time plot suggested that plasma concentrations rise more rapidly with the MEDIPAD device than with the CADD-Micro or oral administrations. The MEDIPAD system showed mild application and injection site reactions; there were no site reactions for the CADD-Micro or oral doses. As expected nausea, somnolence, and abdominal pain occurred more frequently in the oral treatment than the two infusion devices. These data suggest that the MEDIPAD system, which is currently undergoing clinical evaluation, is an acceptable alternative to the traditional oral treatment of morphine sulfate for delivery of analgesics as it allows rapid absorption of morphine; is small, easy to use, and disposable; and achieves plasma levels that are essentially equal to other standard infusion pumps.

Recent studies suggest that opioids can produce analgesia through peripheral mechanisms following inflammation of peripheral tissue. This study examined whether opioids administered prior to inflammation can produce antinociception by peripheral mechanisms in a model of visceral pain. Mice were injected intraperitoneally (i.p.) with 1% acetic acid to evoke abdominal writhing, a standard model of visceral pain. The number of writhes that occurred during 30 min after acetic acid were determined. Intraperitoneal injection of morphine sulfate (60, 90, 100 or 120 microg/0.3 ml) or the peripherally acting opioid loperamide (0.12, 0.36, 1.2 or 3.6 mg/0.3 ml) given 5 min after acetic acid decreased writhing in a dose-dependent fashion. Morphine (100 microg) produced an 70% attenuation in the number of writhes while loperamide (1.2 mg) decreased writhing by 56%. These antinociceptive effects were blocked by pretreatment with the opioid receptor antagonists naloxone (10 mg/kg) and its quarternary version naloxone methiodide (10 mg/kg). To determine whether opioids produced preemptive antinociception via peripheral mechanisms, mice received i.p. injections of morphine (1, 5, and 10 microg/0.3 ml) or vehicle 5 min before acetic acid. Doses of 5 and 10 microg morphine inhibited the number of writhes by 51 and 93%, respectively. The highest dose (10 microg) was ineffective when given intravenously 5 min before acetic acid, suggesting that antinociception following i.p. administration was acting via peripheral mechanisms. These data demonstrate that low doses of opioids, given before or after acetic acid, produce visceral antinociception through peripheral mechanisms. This may be clinically relevant for the management of postoperative abdominal pain.

OBJECTIVE: To identify any systemic effects of topical and subconjunctival administration of atropine sulfate in the horse. Animals studied Six mature grade horses were treated hourly in one eye with topical ophthalmic atropine drops for 24 h. Five horses were treated subconjunctivally in one eye with 3 mg of atropine sulfate. Procedures Pupillary light reflexes, pupil size, electrocardiographic parameters, girth measurements, intestinal motility, and clinical signs of abdominal pain were monitored. RESULTS: Alteration in auscultated gut motility and clinical signs of abdominal pain were the most sensitive indicators of the systemic manifestations of the topically applied atropine. Gut motility was absent in all horses for periods of 2-18 h in all four abdominal quadrants in horses given topically administered atropine. Signs of abdominal pain were observed in four of six horses that received topical atropine. In the subconjunctival test study, gut motility was absent in three horses for periods of 3-7 h. Uniocular subconjunctival injection of 3 mg atropine sulfate produced signs of abdominal pain in one of six horses. Conclusion The ophthalmic administration of atropine can affect gut motility and induce signs of colic in selected horses.

Ingestion of drinking water with a high copper content may induce acute gastrointestinal effects, mainly nausea and vomiting, rarely diarrhea and abdominal pain. The objectives of this study were to define nausea threshold in apparently healthy adult volunteers who received graded concentrations of copper and to explore how individual thresholds were modified by delivering copper in an orange-flavored drink. Sixty-one healthy subjects received 200 mL of a copper-containing solution in purified water, at concentrations 0, 2, 4, 6, 8, 10, and 12 mg/L, as copper sulfate, in random order. Nausea threshold concentration for first response was established and then this threshold was confirmed. Subsequently, following the same design, subjects received the same copper concentrations (up to 12 mg/L), delivered in an orange-flavored drink, starting at the confirmed threshold concentration found in water. Mild nausea shortly after ingestion of copper-containing water was the most frequent finding (33/61 subjects), starting at 4 mg/L; vomiting was observed in 7 individuals, starting at 6 mg/L. The NOEL for copper in purified water was 2 and 4 mg/L for nausea and vomiting, respectively. When copper was provided as an orange-flavored drink, 11 subjects (18%) reported nausea, starting at 8 mg Cu/L, and no subjects vomited up to 12 mg Cu/L. It is concluded that after consumption of copper in purified water, the NOEL is 2 mg Cu/L and the LOAEL 4 mg Cu/L for nausea, while tolerable intake is between 2 and 4 mg Cu/L in water depending on whether apparent or confirmed nausea is used as the criterion to define critical effects.
