Two epidemiologically unrelated outbreaks of trichinellosis were registered in Rostov Province in the November and December of 1984 with 16 patients in the Salsk District and 20 patients in Rostov-on-Don. The course of the disease was characterized by 6-20% of severe and 31-45% moderate forms, respectively. The source of the infection was pork that had not been controlled for Trichinella spiralis. Late diagnosis and inadequate treatment in one case led to a fatal outcome. Economic losses accounted for 490,000 rubles (as of 1985). In spite of energetic prophylaxis measures, the situation in the Rostov Province continues to be serious. In 1989-1992, eighteen cases of trichinellosis were registered in the Salsk District again.
Four new species of blackflies (Diptera: Simuliidae) are described. Helodon rezidentsii Yankovsky, sp. n., Khabarovsk Territory, differs from all known species of the genus with morphology of eyes consisting only of microommatidii in male; from related species H. kamtshaticus (Rubzov, 1940) with large triangular posteromedial lobes of branches of genital fork in female; with number of rays of primary fan of premandibles (20-22, when in H. kamtshaticus 30-32) in larva. Helodon submulticaulis Yankovsky, sp. n., Transbaikalia, differs from related species H. multicaulis (Popov, 1968) with number of rays of primary fan of mandibles (36-40, when in H. multicaulis 26-28), narrow anterior branches of anal sclerite, number of rows of hooks in posterior attachment organ (88-92, when in H. multicaulis 78-80) in larva; with morphology of respiratory organ, consisting of 5-8 lobes bearing 40-60 tune filaments (in H. multicaulis 3-4 lobes bearing more than 150 filaments) in pupa. Sch. samarkandica Yankovsky, sp. n., Uzbekistan, differs from related species Sch. pseudopusilla Rubzov, 1956 with 3 (not 2 as in Sch. pseudopusilla) hooks in parameres, bifurcated lateral branches of X sternite, long projection of gonostyles in male. Schoenbaueria ivdelensis Yankovsky, sp. n., Middle Ural, differs from related species Sch. rangiferina (Rubzov, 1956) with prolonged gonostyles bearing narrow projection in male; with number of rays of secondary fan of premandibles (20-28, when in Sch. rangiferina 44-48), deep ventral groove of cephalic capsule, number of rows of hooks in posterior attachment organ (80-82, when in Sch. rangiferina 70-72) in larva; with morphology of respiratory organ (very long stems of 2 and 3 pairs of filaments) in pupa.
Great experience with treatment and a comprehensive investigation of the severe combined trauma allowed the authors to choose six basic principles to be followed in diagnosing and treatment of this surgical pathology whose peculiarity is the phenomenon of mutual aggravation of the injuries. Following these principles, especially at surgical hospitals, promotes complete diagnosing, choice of the rational treatment policy in order to avoid medical errors and severe posttraumatic and postshock complications and to improve the outcomes. The authors prove expediency of organization of the multifield specialized centers for treatment of patients with the severe combined traumas.
A six-year prospective study of 3775 individuals, first examined in 1978, using an original mathematical program of myocardial infarction risk prognosis, is reported. The program is based on an integral assessment of 19 risk factors, each having 4 degrees of severity. The subjects were allocated to one of 3 groups, depending on the prognostic risk score. In the low coronary risk group (2068 people), there was 1 (0.048%) myocardial infarction over 6 years. There were 12 (0.76%) infarctions in the medium risk group (1569 people), and 62 (44.92%) infarctions in the high risk group (138 people). Therefore, the program is capable of identifying a limited (about 4%) population that is going to develop 80% of all myocardial infarctions within the next 5 or 6 years.
