Strain 13 guinea pigs inoculated subcutaneously with Pichinde virus developed fever, lost body weight, decreased water and food consumption, and died at 14 +/- 0.6 days. After FPL-55712, a leukotriene D4 antagonist, was administered beginning on PID (post-inoculation day) 3 for 18 days, the magnitude of body weight loss decreased and food intake increased, despite a persistent fever. The treated guinea pigs also survived significantly longer than infected animals receiving placebo injection (21 vs 14 days). Using guinea pig ileum bioassay and radioimmunoassay, we detected significant levels of plasma leukotrienes in Pichinde virus-infected guinea pigs on PID 11 and possibly PID 14. These findings strongly suggest that leukotrienes play a role in the pathogenesis of arenavirus infection and may account in part for the observed cardiac depression, pulmonary edema, and eventual death.

The experience of the Utrecht State University with postcoital estrogens in high and low combined doses and with postcoital placement of IUDs since 1964 with over 4000 patients is summarized. The high dose postcoital estrogen treatment consists of 5 mg ethinyl estradiol for 5 days, either orally, or in case of vomiting not controlled by an antiemetic, estradiol benzoate 30 mg by injection. Side effects recorded in 3016 women were nausea in 54%, vomiting in 24%, tender breasts in 23%, menorrhagia in 11%, altered cycle length in 24%. Complications were 1 case of non-fatal pulmonary edema and 1 case of an 8 kg weight gain during treatment. There were 3 pregnancies. The overall failure rate in the whole series was 0.15%, with 10% ectopic pregnancies. There were no thromboembolisms or teratogenic effects. The combined estrogen treatment consisted of 50 mc ethinyl estradiol with 250 mc levonorgestrel (Neogynon oral contraceptive), 2 pills followed by 2 pills 12 hours later. A double-blind randomized trial resulted in no significant differences in pregnancy rates or side effects between the high and low dose regimens. The alternate treatment, if the woman presents more than 72 hours after intercourse, or if estrogens are contraindicated, is postcoital insertion of an IUD. The Dept. of Obstetrics and Gynecology does not place an IUD in a woman with infection nor in case of rape unless there is time for a complete work-up. Nulliparas are informed of the increased risk of pelvic inflammatory disease. Recently, the Multiload-copper 250 and later ML 375 were used exclusively, to achieve better blastocidal effect and lower expulsion rates. The ethical debate over use of postcoital methods centers around the morality of "procuring a miscarriage," but this argument is not relevant since these methods will not terminate a pregnancy once implantation has occurred. In the Netherlands, 25% of all abortion clients become pregnant during their 1st intercourse. In 1982, 35,000 postcoital contraceptives were administered, (roughly 16% of all pregnancies), compared to 15,000 abortions (7% of pregnancies; a total of 23% of pregnancies terminated). Compare these figures with 29% unwanted pregnancies all terminated by abortion in Sweden in that year. The postcoital methods are cheap, effective, and invaluable in emergency cases of rape, incest, intoxication, failure of barrier contraceptives, or unwanted pregnancy in women fearful or opposed to abortion.

Negative pressure pulmonary edema is an uncommon complication of the extubation of the endotracheal tube. An increase in intrathoracic pressure and negative pressure of the lung caused by acute laryngeal spasm results from acute upper respiratory obstruction causing life-threatening pulmonary edema by alveolar-capillary damage is called negative pressure pulmonary edema. We here describe 28-years old female case the preoperative diagnosis of pelvic inflammatory disease undergoing exploratory laporoscopy caused negative pressure pulmonary edema while extubation. With the immediate treatment, the patient was discharged without any abnormalities.
