In Sri Lanka, Russell's viper, Vipera russelli pulchella, kills more people than any other species of snake. At Anuradhapura in the dry central zone of the island we studied 23 patients with systemic envenoming after proven bites. Seventy-three per cent had swelling at the bite site. Neurotoxicity was the commonest sign of systemic envenoming: 82 per cent had external ophthalmoplegia and 77 per cent had ptosis. Incoagulable blood was found in 59 per cent but only 36 per cent had spontaneous bleeding. Other signs included generalized muscle tenderness (32 per cent), black urine (27 per cent) and persistent oliguria (9 per cent). Laboratory studies showed evidence of a severe clotting disorder: fibrinogen was often depleted as were factors V and X. Fibrin degradation products, including cross-linked moieties, were grossly elevated, clear evidence for enhanced fibrinolysis. Intravascular haemolysis, unrelated to G6PD deficiency, was often present. Myoglobin was detected in the plasma of all 19 patients tested (range 100- greater than 8000 ng/ml) and in the urine in 14 of 18 patients (110- greater than 16,000 ng/ml). Venom antigen (16.5-702 ng/ml) was detected by specific ELISA in the serum of all patients. Its concentration fell with the administration of 50-200 ml of Haffkine polyspecific antivenom raised against Indian venoms. Complete permanent clearance of venom antigen from the circulation was seen in only one of 21 patients who were followed until discharge. Blood coagulability was restored between one and 25 h (mean 8.8) after the first dose of antivenom in the 12 surviving patients whose clotting defect could be followed; no dramatic reversal of neuromyotoxic signs was seen. Haffkine antivenom thus has limited efficacy against systemic poisoning by Russell's viper in Sri Lanka.

This study determines whether or not fibrin deposits occur more frequently in patients who had gynecologic surgical procedures for prolapse of uterus and treated with estrogens than in those in a control group. 11 women were given 50 ug of ethinyl estradiol daily for 3 weeks while 8 women were given 200 ug ethinyl estradiol daily for 12 days. The remaining 157 women who received no hormonal treatment served as controls. The women were examined postoperatively by the Iodine fibrinogen uptake test and phlebography according to the method of Nylander. The chi-square test with Yate's correction was used for data analysis. Fibrin deposits were found in 6 of the 11 women who received 50 ug ethinyl estradiol for 3 weeks and in 4 of 8 women receiving 200 ug for 12 days. Corresponding figures for the control group were 18 of 157, p 0.001. Estrogens should not prescribed to patients preoperatively. Estrogen therapy should be discontinued in patients who are about to be operated.

Twenty two cases of colorectal mucosal prolapse from a variety of clinical situations were examined histologically to identify changes in the microvasculature which may predispose to ulceration. The findings were compared with 10 tubular adenomas and 10 hyperplastic polyps. Fibrin insudation into vessel walls and thickened mucosal vessels were significantly associated with the presence of ulceration. Possible mechanisms of ulceration are discussed, and an hypothesis based on a microvascular pathogenesis is presented.

Of the filtering procedures employed, trabeculectomy is the one most frequently used for surgical therapy in primary open angle glaucoma patients. Intra- and postoperative complications must be detected promptly and treated adequately. Many complications arise within the first weeks, such as bleb scaring, decreased flow beneath the scleral flap, extensive filtration with choroidal detachment and anterior chamber narrowing. Fibrin reaction, corneal dellen, iris prolapse, conjunctival leakage and ciliary body detachment are seen more rarely. With prophylactic pre- and perioperative application of antibiotics, wound infections are rare and the risk of endophthalmitis following trabeculectomy remains small. Careful surgical planning requires special consideration of the conjunctiva and provides the basis for long-term success as long as intensive follow-up treatment is ensured. The success of trabeculectomy depends on the preoperative, intraoperative as well as postoperative condition and in particular on bleb development. Early detection of postoperative complications, especially in terms of early scaring in the bleb area, enables implementation of adequate therapeutic measures, such as needling procedures and early bleb revision. Close patient monitoring substantially increases long-term success rates.
