[Roentgenosurgery for aortic coarctation and open arterial duct with intravascular ultrasonic examination].

Forty-five patients (32 with open arterial duct and 13 with aortic coarctation) were examined. Forty-nine intravascular ultrasonic examinations were performed, qualitative and quantitative analysis of 139 vascular segments was carried out. Despite the fact that mean morphometric indices of open arterial duct and aorta in angiography and intravascular ultrasonic examination had no significant difference, real confidence of the o data was seen only in 13.3% cases for open arterial duct an in 16.7% cases--for aortic coarctation. In 37.5 and 50% patients, respectively, difference in the dimensions was so significant that dictated choice of instruments with difference size. Roentgenoendovascular surgeries were performed in 23 patients with open arterial duct and in 12--with aortic coarctation. Choice of instruments parameters based on data of intravascular ultrasonic examination provided safer and more efficient procedures.

[Errors in the microbiologic diagnosis of shigellosis].

The authors analyze the diagnostic errors that occurred at bacteriologic laboratories of one of the districts of Russia and that led to misrepresentation of the true etiologic structure of acute enteric infections and therefore to useless ineffective antiepidemic measures. They emphasize strict adherance to a certain order of stages of laboratory diagnosis and to methodologic recommendations on microbiologic diagnosis of diseases induced by enterobacteria.

[The characteristics of the biological properties of Shigella dysenteriae 1 circulating in the USSR and India: its biochemical activity and agglutinability].

The properties of 71 S. dysenteriae 1 strains isolated from patients in the USSR and India in 1986-1988 were studied. The cultures possessed typical biochemical and serological properties. As revealed in this investigation, high fastidiousness of this infective agent to the quality of synthetic nutrient could become the cause of false negative reactions in different substrates used for the identification of enterobacteria, thus leading to diagnostic mistakes. The variability of the biochemical activity of different strains with respect to arginine, glycerol, maltose and trehalose (as well as the stability of these signs) was regarded as the theoretical substantiation of the possibility, in principle, to work out the scheme for the subdivision of S. dysenteriae 1 into independent biochemical variants.

[The epidemiological characteristics of the spread of Grigor'ev-Shiga dysentery in the territories of the former USSR in recent years].

On the basis of special data on the registered cases of Grigor'ev-Shiga dysentery on the territory of the former USSR the spread of this nosological form of Shigella infections since 1980 until the present moment has been analyzed. As shown by this analysis, Grigor'ev-Shiga dysentery is not widely spread on the whole territory of the former USSR, the cases of this disease being mostly registered in Namangan (the Uzbek Republic). The study has shown that the area of the circulation of Shigella dysenteriae 1 is not completely determined. This disease is quite widely spread in some areas of Central Asia, penetrating from these areas to other regions. Everyday contacts have shown to play the main role in the transmission of S. dysenteriae 1 due to poor municipal sanitation facilities and pronounced deficiency in the level of general and sanitary education. The withdrawal of Soviet troops from Afghanistan has led to the rapid improvement of the epidemiological situation on the territory of the former USSR as the result of a sharp decline in the "import" of Shigella dysenteriae 1.
