[Clinical and laboratory presentation of the influenza A (H1N1pdm 2009) in children and adults during the period of 2009-2013 in St. Petersburg].

Comparative analysis of the clinical laboratory data from 419 children and 468 adults hospitalized during the pandemic of A (H1N1pdm 2009) and pre- and post-pandemic periods (2010-2013) showed that the clinical presentation of the pandemic influenza in patients of all ages is generally typical for influenza, and its character is determined by the degree of involvement of lungs in the process. Besides, the incidence of pneumonia in adults is statistically significantly higher than in children. During all compared periods hyperthermia (≥ 39 degrees C), hemorrhagic and dyspeptic syndrome were observed.

Recognition of stable distribution with Lévy index α close to 2.

We address the problem of recognizing α-stable Lévy distribution with Lévy index close to 2 from experimental data. We are interested in the case when the sample size of available data is not large, thus the power law asymptotics of the distribution is not clearly detectable, and the shape of the empirical probability density function is close to a Gaussian. We propose a testing procedure combining a simple visual test based on empirical fourth moment with the Anderson-Darling and Jarque-Bera statistical tests and we check the efficiency of the method on simulated data.

[Effect of losartan, lisinopril and their combination on hemodynamics and morphofunctional parameters of the heart in patients with chronic cardiac failure].

The aim of the study was to evaluate effects of losartan receptor I antagonist (AT) and/or angiotensin converting enzyme inhibitor (iACE) on clinical manifestations of the disease, hemodynamic characteristics, morphofunctional heart parameters in patients with chronic cardiac insufficiency (CHI) complicating coronary heart disease (CHD). A total of 60 patients aged 48-72 (mean 62 +/- 8.4) years with persistent symptoms of functional class II-IV CHI and left ventricular (LV) fraction = < 45% complicating CHD.

[Clinical trial of safety and immunogenicity of new influenza vaccine Grifor in children].

Aim: Assessment of reactogenicity, safety and immunogenicity after single intramuscular immunization of children with Grifor vaccine.

Materials And Methods: Reactogenicity, safety, and immunogenicity of Grifor vaccine compared with Vaxigrip vaccine was evaluated during phase III clinical trial in the Institute of Influenza. Thirty-six children aged 12 - 17 years, divided on 2 groups, participated in single blind comparative prospective randomized trial.
