The main benefits of intrauterine devices (IUDs) are a lack of adverse systemic effects, excellent effectiveness, high continuation rates and the single act of motivation required for use. First year failure rates range from 2% to 3%, but decline steadily thereafter to a cumulative annual failure rate of less than 1% after six years. The risks of IUDs include increased blood loss, uterine perforation, pelvic infection and pregnancy-related complications. The incidence of perforation of the uterine fundus ranges from 1:1000 to 1:2500 insertions, while that of cervical perforation with the copper devices ranges from 1:600 to 1:1000. IUD use is associated with about a three-fold increased incidence of developing acute salpingitis in comparison with use of oral contraceptives and diaphragms. If pregnancy occurs with an IUD in place, there is a three-fold increased risk of spontaneous abortion, a ten-fold increased risk of ectopic pregnancy (5% of all IUD pregnancies) and a possible increased incidence of sepsis during the pregnancy.

Insertion of one of three types of intrauterine contraceptive device--the Lem, copper 7, and 'Progestasert' system--was carried out in 274 obstetric patients. These devices were all inserted within 20 min of delivery of the placenta and membranes, with a special 25 cm inserter. The expulsion-rate was low (less than 7%), and there were no uterine perforations. There was no difference in puerperal morbidity between these patients and a matched control group, and no cases of pelvic sepsis developed.

Eleven out of a series of twenty-nine patients (37-9%) with acute copper sulphate poisoning developed acute renal failure. Intravascular haemolysis appeared to be the chief factor responsible for renal lesions in these patients. Histological lesions observed in the kidney varied from those of mild shock to well established acute tubular necrosis. In one case, granulomatous lesions were seen in response to tubulorrhexis. Renal failure was the chief indication for dialysis in ten patients, whereas one patient was dialysed primarily for removal of copper. Notwithstanding the adequate control of uraemia by dialysis, only six of the eleven patients recovered. Septicaemia was responsible for death in three, hepatic failure in one and methaemoglobinaemia in another. It is postulated that release of copper from haemolysed red cells during acute haemolytic episodes may initiate, or contribute to, the development of renal damage.

Peroxynitrite (ONOO-), the reaction product of superoxide (O2-) and nitric oxide (NO), may be a major cytotoxic agent produced during inflammation, sepsis, and ischemia/reperfusion. Bovine Cu,Zn superoxide dismutase reacted with peroxynitrite to form a stable yellow protein-bound adduct identified as nitrotyrosine. The uv-visible spectrum of the peroxynitrite-modified superoxide dismutase was highly pH dependent, exhibiting a peak at 438 nm at alkaline pH that shifts to 356 nm at acidic pH. An equivalent uv-visible spectrum was obtained by Cu,Zn superoxide dismutase treated with tetranitromethane. The Raman spectrum of authentic nitrotyrosine was contained in the spectrum of peroxynitrite-modified Cu,Zn superoxide dismutase. The reaction was specific for peroxynitrite because no significant amounts of nitrotyrosine were formed with nitric oxide (NO), nitrogen dioxide (NO2), nitrite (NO2-), or nitrate (NO3-). Removal of the copper from the Cu,Zn superoxide dismutase prevented formation of nitrotyrosine by peroxynitrite. The mechanism appears to involve peroxynitrite initially reacting with the active site copper to form an intermediate with the reactivity of nitronium ion (NO2+), which then nitrates tyrosine on a second molecule of superoxide dismutase. In the absence of exogenous phenolics, the rate of nitration of tyrosine followed second-order kinetics with respect to Cu,Zn superoxide dismutase concentration, proceeding at a rate of 1.0 +/- 0.1 M-1.s-1. Peroxynitrite-mediated nitration of tyrosine was also observed with the Mn and Fe superoxide dismutases as well as other copper-containing proteins.

Diseases of striped bass, their hybrids, and redfish (red drum) are important constraints to the culture of these two species. Since striped bass have been cultured for years the organisms that cause most diseases of these fish are well known, but very little specific disease information exists for redfish. However, it appears that the organisms that cause diseases of striped bass and redfish do not differ greatly from those of other fishes. The most significant viral disease is lymphocystis, but infectious pancreatic necrosis has occurred in striped bass. Vibriosis (Vibrio sp.) and motile Aeromonas septicemia (Aeromonas hydrophila) are the most frequently encountered bacterial diseases. Both species of fish are affected by fungi (usually Saprolegnia) when the fish are injured or stressed. Amyloodinium ocellatum is the most serious protozoan that infects striped bass and redfish, but the other common protozoans (Trichodina, Ichthyophthirius, Cryptocaron, etc.) have also been reported. Treatment of any of these diseases is a problem because of the absence of approved drugs or chemicals for use on striped bass or redfish. The most common therapeutics used on striped bass and redfish are copper sulfate, formalin, salt (in freshwater) and Terramycin.

Tumor necrosis factor (TNF) is a peptide secreted by macrophages in response to endotoxin that can produce many of the changes seen in septic shock. After cecal ligation and puncture (CLP) rats gradually develop tachycardia, hypotension, tachypnea, and hypothermia. At 5 h post-CLP, rats have a peak in serum levels of endotoxin and 60% of rats have blood cultures that grow Gram-negative rods (Escherichia coli and Klebsiella pneumonia). At 20 h post-CLP all rats develop positive blood cultures. Serum levels of TNF are not reproducibly measurable in rats following CLP. Rats undergoing CLP have a 50-80% mortality with deaths usually occurring 24-72 h postinjury. Repetitive (twice daily x 6 d) i.p. injection of sublethal doses of recombinant human TNF-alpha (100 micrograms/kg) to rats undergoing CLP 1 d after the treatment period resulted in a significant reduction in mortality compared to control rats previously unexposed to rTNF (P less than 0.03). Animals treated with rTNF had no hypotension or hypothermia after CLP and regained normal food intake faster than control rats. 12 h after CLP the gene expression for manganous superoxide dismutase (MnSOD), an inducible mitochondrial metalloenzyme responsible for cellular resistance to injury from toxic reactive oxygen species, was higher in livers of rats treated with rTNF suggesting that the TNF treatment augmented expression of this protective enzyme. Unlike MnSOD, expression of the gene for copper-zinc SOD was not affected by CLP or rTNF treatment. The results suggest that prior treatment with recombinant TNF can ameliorate the lethality, hypotension, hypothermia, and anorexia of Gram-negative sepsis in rats and that the mechanism may be related to enhanced hepatic expression of the gene for MnSOD. Repeated administration of recombinant TNF may be a strategy to minimize mortality and morbidity of Gram-negative sepsis.

The object of this is to evaluate the influence of several micronutrients on the survival rate of septic patients following abdominal surgery. A retrospective assessment was done of sixty-one patients suffering from neoplastic or non-neoplastic pathology associated to septicemia. On admission the following parameters were determined: number of total lymphocytes, serum albumin, transferrin, zinc, copper, magnesium, iron, calcium, phosphorus, and copper/zinc levels. The differences obtained between surviving and non-surviving patients were analyzed. The most relevant findings revealed statistically significant lower serum albumin, zinc and transferrin values in the latter group. We conclude by stating that such parameters may be of prognostic value in this type of patients, and that supplemental micronutrients must be administered in order to improve prognosis.

This is a comprehensive review of the risk of infertility or adverse effects on pregnancy outcome, such as chromosomal or congenital birth defects, amenorrhea, pelvic inflammatory disease (PID), or spontaneous abortion, after use of oral contraceptives, IUDs, induced abortion or spermicides. The sequelae reported for orals are chromosomal abnormalities, the VACTERL anomalies, masculinization of female fetus, Down's syndrome and post-pill amenorrhea. Several large studies found no increased risks for birth defects, although the risk of malformations when pregnant women inadvertently take the pill in early pregnancy was high in 1 of 2 such studies. Masculinization was reported with high dose combined hormone treatment and in 2 infants of a woman who took Enovid. the bulk of recent studies on secondary amenorrhea indicate that it is rare, but just as likely to occur in women with prior normal or abnormal menstrual patterns. One study found that amenorrhea is 7.7 times more likely to develop in women who took the pill to regulate menses. It is recommended that women with amenorrhea be screened for pituitary tumors and counseled before prescribing pills, and that those who fail to ovulate after stopping the pill be treated at least 6 months with clomiphene. A massing of all studies on the impact of 1st trimester induced abortion on subsequent fertility, premature delivery and spontaneous abortion, shows all relative risks around 1.0. After multiple abortions, the results are conflicting. In contrast, prior series analyzing illegal abortion have an unquestioned adverse effect on fertility and pregnancy outcome. Asherman's syndrome, a rare disorder of intrauterine adhesions, menstrual abnormalities, infertility and habitual abortion, has been associated with D & C abortion concurrent with pelvic sepsis, or traumatic pregnancy with D & C. This condition can be treated with moderate success. The bulk of IUD studies conclude that there is no overall decrement in fertility, while some disaggregated studies point the Dalkon shield as a higher risk and copper IUDs as a lower risk. PID and its consequences are now considered related to the immediate post-insertion time frame, or specifically to women who are at risk of contracting sexually transmitted disease, i.e., those with multiple partners, those with prior PID and nulliparas. Comprehensive review of current large series on spermicides shows no relationship between their use and spontaneous abortion or congenital malformation.

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS), a visceral myopathy causing intestinal obstruction in the newborn, is a generally fatal condition, with death being secondary either to sepsis or to malnutrition if long-term intravenous feeding is not provided. A patient with MMIHS is described who has been raised by total parenteral nutrition (TPN) for seven years since her birth. Severe hepatic dysfunction was encountered in early infancy, which gradually cleared after the initiation of milk feeding by mouth, although the milk could not be absorbed because of the high-output jejunostomy. The patient also experienced a bone disease similar to scurvy but caused by copper deficiency at the age of 9 months. The central venous catheter now in situ is the 25th one for the patient. When these catheters were evaluated, the Broviac proved more efficacious than the traditional Silastic for use in long-term TPN. The patient does not yet have normal bowel function and still requires TPN.

The pattern of acute renal failure in third-world countries is changing albeit at a slower pace compared to that in developed countries. Of the 1862 patients with acute renal failure requiring dialysis between 1965 and 1986 in a north Indian centre, 60, 15 and 25 per cent were related to medical, obstetrical and surgical conditions respectively. Among the medical patients, diarrhoeal diseases which caused 23 per cent of the total number of cases of acute renal failure in the period 1965 to 1974 caused only 10 per cent in 1981 to 1986. In the same period, acute renal failure due to sepsis and drugs increased while that due to copper sulphate poisoning and intravascular haemolysis showed a downward trend. Obstetrical acute renal failure declined from 22 per cent in 1965 to 1974 to 9 per cent during the period 1981 to 1986. This decline was chiefly due to a fall in cases of septic abortion, puerperal sepsis and postpartum haemorrhage. Surgical acute renal failure increased from 11 per cent during the period 1965 to 1974 to 31 per cent in the 1980s, predominantly due to an increase in patients with obstructive uropathy. Despite these favourable trends, the pattern of acute renal failure in the third world continues to be different from that in the developed countries.
