[The peculiarities of the influenza epidemics in some areas of Russia during 2012-2013 season. The influenza A (H1N1) pdm09 virus domination in European countries].

The peculiarities of the influenza viruses circulation in 2012-2013 are discussed. The results were obtained in 10 cities of Russia, where basic laboratories of the Influenza Ecology and Epidemics Center of on the basis of Ivanovsky Institute of Virology, Ministry of Health of the Russian Federation, are situated. The increasing rate of the ARD morbidity caused by influenza viruses was observed in January-March 2013. The highest indices of the morbidity were detected during 6-7 weeks with the following decreasing rate till threshold levels to week 14. The influenza A (H1N1) pdm09, A (H3N2), and B viruses were the cause of the epidemic, but their activity differed over areas of Russia. The results of study of the antigenic and genetic properties of the influenza strains demonstrated closed relatives with respect to vaccine strains. In addition, some heterogeneity of the circulating strains and their drift variants were found as well. All tested strains were sensitive to oseltamivir (excluding one A (H1N1) pdm09 strain), zanamivir, arbidol, and remained resistant to rimantadine. The ratio of the ARD viruses was comparable with the last epidemic seasons.

[Efficiency of the influenza A and B viruses isolation from nasopharyngeal swabs taken in the test tubes Sigma-Virocult (M40 Compliant, Sigma Virocult) and Virocult (M40 Compliant, Virocult) in 2010-2011 epidemic season].

The goal of this work was to compare the efficiency of the influenza A and B viruses Isolated during 2010-2011 epidemic season. The clinical samples were taken in the test tubes with the transport medium on the.basis of the medium EMEM and commercial test tubes Sigma-Virocult (M40 Compliant, Sigma Virocult) and Virocult (M40 Compliant, Virocult). The results of this work demonstrated higher efficiency of influenza A and B viruses isolation from nasopharyngeal swabs of the patients taken in the test tubes Sigma-Virocult (M40 Compliant, Sigma Virocult) and Virocult (M40 Compliant, Virocult) with the transport medium as compared with the efficiency of influenza strains isolation from nasopharyngeal swabs taken in test tubes with the medium EMEM with respect to all estimated indicators: efficiency of isolation, a passage of isolation and the titer of isolates. The possibility of the long-term storage of a clinical material at room temperature and at 4 degrees C was confirmed, without resorting to freezing, which is significant in the absence of the necessary equipment.

[Development of the influenza epidemic in season 2011-2012 in some areas of Russia: results of activity of the Influenza Etiology and Epidemiology Center of the Ivanovsky Institute of Virology].

The results of analysis of the peculiarities of the epidemic 2011-2012 development in the areas of 10 cities of Russia obtained by basic laboratories of IEES on the base of D.I. Ivanovsky Research Institute of Virology, Ministry of Public Health and Social Development of Russia, are presented. The increasing ARD morbidity caused by the influenza viruses was detected rather late--in February-March 2012. The highest indices of the morbidity were detected during weeks 10-13 followed by decreasing to threshold levels by week 27. Children 0-2 and 3-6 years old were involved the most, meantime the high rate of hospitalization was found for 15-64 years old aged group (25%). Influenza A(H3N2) and B viruses were the cause of the epidemic. The results of studies of the antigenic and genetic properties of the influenza strains showed most of them to be close relatives to the vaccine strains. Some heterogeneity of circulating strains and their drift variants were found as well. All tested strains were sensitive to arbidol, oseltamivir and zanamivir, and saved resistance to rimantadine. The ratio of ARD viruses was comparable with the last epidemic seasons.

[The specific features of the cocirculation of influenza viruses in the 2010-2011 postpandemic period according to the results of activities of the D. I. Ivanovsky Research Institute of Virology, Ministry of Health and Social Development of Russia].

The paper gives the results of monitoring the circulation of influenza viruses in the 2010-2011 season, that covers the second year of circulation of pandemic A(H1N1)v virus strains, and their interaction with seasonal A (H3N2) and B strains. Unlike the previous season, the beginning of an increase in morbidity was recorded in January 2011; its peak in the most of contiguous areas was noted at 5-7 weeks of 2011, with its further decline to threshold levels at week 11 of 2011. Preschool and school children were most involved in the epidemic process. Three influenza virus strains (A(H1N1)v, A(H3N2), and B) were found to circulate. Differences were found in the level of participation of the isolated strains in individual areas of the Russian Federation. Detailed typing of the isolated strains determined the compliance of the vast majority of them with vaccine viruses. The pandemic influenza A(H1N1)v virus strains retained their susceptibility to oseltamivir and were resistant to rimantadine. The participation of non-influenza acute respiratory viral infection pathogens was estimated as follows: 11.9% for parainfluenza viruses, 5.9% for adenoviruses, and 3.5% for PC viruses, and 0.7% for pneumonia Mycoplasma, which was comparable with the previous epidemic seasons.

[Experimental investigations of the analgesic activity of fentanyl and the non-opiodal agents -clonidine and isradipine, and protease inhibitors].

The analgesic activity of clonidine, isradipine, antagosane (aprotinine), transamine, and their combinations with fentanyl in subanalgesic doses was experimentally studied on mice, by using the tail-flick test. Analgesic activity was found in clonidine, antagosane, and transamine. A combination of fentanyl used in subanalgesic doses and clonidine, isradipine, antagosane, or transamine had supertotal analgesic activity. The findings serve as a basis for effectively making up a component of analgesia during anesthetic support at surgery made in patients with baseline sympathicotonia, ischemia/reperfusion syndrome, and a systemic inflammatory reaction.

[Optimization of anesthetic maintenance of a facial dermabrasion operation].

Facial dermabrasion requires the preservation of natural mimic muscle tone, adequate spontaneous respiration, and contact with a patient. By taking into account the commercial pattern of surgical interventions, anesthesia should be as safe and comfortable as possible. For these purposes, the standard procedure of intravenous anesthesia with spontaneous respiration being preserved is optimized on the anticipatory analgesia principle, by using analgesics having the non-opiate mechanism of action: the kininogenesis inhibitor transamine and the nonsteroidal anti-inflammatory drug ketonal. This makes it possible to provide the adequacy of anesthesia and a good cardiovascular response with the doses of narcotic analgesics, hypnotics, and an anxiolytics, which do not cause respiratory distress, and to avoid using narcotic analgesics. The use of the antiemetics tropisetron and dexamethasone at the induction stage of anesthesia has been ascertained to be a reliable preventive measure against postoperative nausea and vomiting, by substantially enhancing its comfortability.

[Optimization of anesthetic management in blepharoplasty]. / Optimizatsiia anesteziologicheskogo obespecheniia operatsii blefaroplastiki.

The anesthetic management in cosmetic surgery must be as much controllable, safe and comfortable for a patient as possible, i.e. it must be in line with all requirements of outpatient surgery. Fifty-two patients were added, to the anesthetic-management scheme in blepharoplasty, the following: ketoralak - 0.4-0.6 mg/kg, transamine - 13.5-15 mg/kg, analgetics with non-opiate effect and antiemetic tropisetron - 0.05-0.08 mg/kg. It ensured an adequate analgesic action without suppression of the breathing function and a more comfortable postoperative course with a lesser postoperative syndrome of nausea and vomiting - by 3-4 times less versus the controls.
