[SONNEI DYSENTERY MORBIDITY IN KHABAROVSK AND KHABAROVSK REGION DUE TO ATYPICAL MANNITOL-NEGATIVE CAUSATIVE AGENT].

AIM: Determine features of epidemic process (EP) of Sonnei dysentery in Khabarovsk Region in 2012 - 2014 due to atypical causative agent. MATERIALS AND METHODS: Detailed characteristics of 161 cultures of Shigella sonnei isolated from 81 patients from epidemic focus in children boarding school in Bikin as well as from 22 patients from sporadic and group foci of dysenteryin Khabarovsk (biochemical type, colicin-genotype, spectrum of drug resistance) is given. Molecular-biologic subtyping was carried out for 11 strains by Pulsed Field Gel Electrophoresis method (PFGE). RESULTS: Materials of observation of a prolonged foci of Sonnei dysentery with contact-domestic transmission route of the infection in children boarding house for disabled (October 2012 - September 2014) are presented. The diseases are etiologically connected with atypical mannitol- negative types of shigella isolated for the first time in 40 years of observation in Khabarovsk region. Epidemic process of shigellosis was supported by prolonged carriership of the causative agent in patients and special contingent ofthe nursing home. Shigella cultures isolated in the focus belonged to the same colicin-genotype and 2 distinct drug resistance clones, but a single genotype established by PFGE method. CONCLUSION: Results of the studies give evidence on the importance of determi- nation of traditional phenotypic and contemporary genotypic variants of shigella and the neces- sity of search for arguments, additional methodic approaches for establishing similarities and differences of shigella isolates from within the same outbreak of the diseases as well as for com- parison of strains circulating in different territories.

[The sanitary and hygienic state of solid garbage burial grounds in the stages of a life cycle].

The purpose of the study was to assess the sanitary-and-hygienic state of solid garbage (SG) burial grounds in the Perm Territory in different stage of a life cycle. This paper presents the results of the study of deposited waste, forming dump soil, and SG ground emissions by general sanitary and sanitary-microbiological parameters and their effect on environmental objects. The performed studies of the sanitary-and-hygienic situation on some grounds of the Perm Territory suggest that there is a need for setting up a system for sanitary-and-monitoring of SG ground and for elaborating engineering, organizational, and prophylactic measures to assure the sanitary-and-hygienic safety of objects and to control the quality and quantity of waste to be buried and the currents of emissions (ground body degassing, filtrating sewage drainage and purification).

Comparative assessment of pediatric intensive care in Moscow, the Russian Federation: a prospective, multicenter study.

OBJECTIVE: Comparative assessment of pediatric intensive care. DESIGN: Prospective multicenter study. SETTING: Four pediatric intensive care units in Moscow, the Russian Federation. PATIENTS: Consecutive unselected admissions (n = 583), < or = 14 yrs of age, in a 6-month period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Effectiveness was defined as the ratio of observed to predicted mortality, based on prediction by Pediatric Risk of Mortality (PRISM) severity of illness scoring. Efficiency (on the day of admission only) depended on either a mortality risk of > 1% or the administration of intensive care unit-dependent therapies. In all four hospitals, observed mortality rates were higher than expected, with a range of standardized mortality ratios between 1.10 and 1.83 (mean 1.32). The excess mortality was found in the low- and medium-risk strata (risk of mortality of < 1% to 15%). Admission efficiency ratings did not fluctuate greatly between institutions (mean 60.4%, range 55.7 to 65.9). CONCLUSIONS: We provided a quantitative description and assessment of pediatric intensive care in Moscow. Moderate efficiency may reflect a low threshold for ICU admission due to poor nurse/patient ratios on the wards. Effectiveness in the low- and medium-risk strata is below standard, as compared with a Western reference population. Excess mortality was concentrated in the low- and medium-risk strata, and can only partially be explained by the inclusion of co-morbidity. Future analysis should focus on specific treatment protocols, protocol adherence, and the determination of infectious and therapeutic complications.

[The prevalence of disseminated sclerosis in the southern region of Ukraine]. / Rasprostranennost' rasseiannogo skleroza v iuzhnom regione Ukrainy.

Some aspects were studied of the occurrence of disseminated sclerosis (DS) in the south of Ukraine (Odessa and Nikolaev Provinces) with special reference to geoclimatic, ecological and ethnic factors over the period 1992-1993, DS incidence was noted to be on the increase in the region, which fact permits classifying the South territories of Ukraine as a zone with moderate DS prevalence. Data are submitted on nonuniformity of distribution of frequency of DS cases on the territory in question. Lineage was traced to the climatic-and-geographic factors of the region, locality one lives in as well as to sex and race.

[The intensity of respiration in pea and corn seedlings under high-altitude hypoxia]. / Intensivnost' dykhaniia prorostkov gorokha i kukuruzy v usloviiakh vysotnoi gipoksii.

Dynamics of CO2 gas-exchange and enzymatic activity of the respiratory metabolism of pea (Pisum sativum L.) and maize (Zea mays L.) seedlings during hypobaric hypoxia simulating the altitude of 5000 m above the sea level was studied. In the 48-hour chamber experiment (total barometric pressure is 54 kPa, partial O2 pressure is 11 kPa), the relative intensity of CO2 emission was found to increase and be essentially higher for pea than maize. Periodic reactions with small upward spikes and time offset were recorded in the pea plants. The initial increase of CO2 emission velocity by maize rapidly reached the level of saturation and since then remained constant. High velocity of the main catabolic ways and carboxylating activity in maize seedlings was the effect of hypoxic stress. Utilisation of respiratory substrates by pea seedlings was blocked at the Krebs cycle level, whereas glycolysis and oxidizing pentose phosphate pathways were activated. Weak activity of the carboxylate system does not provide refixation of endogenous carbon dioxide, excessive quantities of which invade the environment.
