The study presents the results of clinical and laboratory observations 121 children aged 3 to 36 months with the diagnosis «ARVI with convulsive syndrome».  The prevalence of patients with burdened hereditary anamnesis for the development of febrile seizures (FS) (31.4 ± 4.2%). During the laboratory examination along with the respiratory viruses group noted the high herpes virus infection (51.2%), particularly human herpes virus 6 type (of 38.7%). The extension of the spectrum of the diagnostic examination of children  with FS will establish  the role of infectious triggers in the occurrence of FS and thereby define rational tactics and dispensary observation of this group of patients.

To describe the spectrum of neurological complications in children with varicella and against the background of herpes zoster. The study included children at the age of 0—16 years (n = 84), who recovered from exanthematous form of the disease not longer than 21 day before the appearance  of neurological symptoms (n = 82) or presented with herpes zoster (n = 2). Results: Clinical syndromes  included acute cerebellar ataxia (n = 37), meningoencephalitis (n = 34), meningitis (n = 7), polyradiculoneuropathy (n = 4), acute disseminated encephalomyelitis (n = 1), and ischemic stroke (n = 1). The period from varicella onset to the appearance of neurological symptoms was 6 [5;8] days. We have not lethal cases. Аcute cerebellar ataxia is most common  postvaricella complication  in children.

The article presents the current clinical and epidemiological features of enterovirus infection in children of Krasnoyarsk Territory. A retrospective analysis of the incidence of enterovirus infection and enterovirus meningitis in the period 2014—2015 according to the forms of state statistical reporting №2 «Information on infectious and parasitic diseases». Clinical and epidemiological analysis of enterovirus infection in 454 children who were treated at MBUZ «City Children's Infectious Hospital №1» in the period of seasonal rise of morbidity in 2014 revealed a prevalence of etiological structure of enteroviruses Coxsackie B, Coxsackie B5, Coxsackie B3, Coxsackie B4. The region recorded the different clinical forms of enterovirus infection (rash, myalgia, diarrhea, gerpangina), the structure of which is still, aseptic meningitis prevails.

In this article are presented the results of comparative of experimental (on cell cultures) study of the influenza virus strains sensitivity to neuraminidase  inhibitor — Oseltamivir and blocker of M-canal — Rimantadin аnd the results of study effectiveness of the inclusion in the complex therapy of 331 hospitalized patients (children and adults) rapy of А(Н1N1)pdm09 antiviral drug — inhibitor of neuraminidase Oseltamivir that occurred during the epidemic seasons 2009—2010 and 2015—2016  in terms of observational clinical studies.  It is shown that this drug, can be successfully used in the treatment of children and adults with influenza А(Н1N1)pdm09 during 8—9 years after beginning of pandemic cycle.

In this article are presented the results of comparative observation of the effectiveness of the inclusion in the complex therapy of 203 hospitalized children aged 2 years and older with influenza А(Н1N1)pdm09 domestic antiviral drug — Umifenovir  (Arbidol) that occurred during the epidemic seasons 2009—2013 and 2015—2016 in terms of observational clinical studies.  It is shown  that this drug, possessing a wide spectrum of antiviral activity, including against Oseltamivir — and Zanamivir-resistant influenza virus strains, antioxidant activity and low toxicity (Code ATX Ј05АХ13), can be successfully used in the treatment of infants with influenza А(Н1N1)pdm09.

Conducted clinical and immunological examination of 51 children with acute Epstein-Barr viral mononucleosis (EBV) in age from 1 year to 7 years. All children diagnosed with a moderate degree of the disease. In the treatment of 25 people (comparison group) used the standard treatment (pathogenetic, symptomatic), treatment 26 people (main group) included the use as antiviral and immunotropic means of the preparation of human recombinant interferon Alfa-2b in the form of rectal suppositories — VIFERON®. The immunological survey was conducted in dynamics: at the height of the disease and in the convalescence period. The blood was determined indicators of cellular immunity (leukocytes, lymphocytes, CD3+, CD4+, CD8+, CD56+, HLAII+, CD95+, CD1 6+, CD25+), the concentration of IFN-a, IFN-y, IL-4 levels in spontaneous and induced production, in the serum). At milestones children of the main group noted rapid regression of clinical symptoms, normalization of body temperature, reducing intoxication, positive dynamics lymphoproliferative syndrome), a significant reduction in bed-days, no layering respiratory viral infections. Interferon had also expressed a positive impact on the changed parameters of cellular immunity and cytokine links. At the same time, 80% of patients after basic treatment is established the predominance of Th2 type immune response, indicating a high risk of developing chronic course of EBV-mononucleosis.

This article presents a scheme of antibiotic treatment of children with acute sinus infections, paired with Chlamydial  infection, which is based on the use of cyclic poliantibiotikoterapii macrolide drugs. The most significant advantage of this therapy is the high degree of eradication of Chlamydial agent (87.5 %), which allows high-quality conduct antichlamydial treatment prevents the chronization inflammation, disseminated infection and helps reduce the number of complications. Recommended for use in medical practice physicians otorhinolaryngology for the treatment of acute sinusitis in children,  coupled with the Chlamydial infection.

This review presents an analysis of the literature data on the etiology and pathogenesis  of Herpetic Eczema (Kaposi's Eczema). Modern views on the complex genetic and phenotypic determinants of disease, reflecting the complex interactions between the skin and the immune system. Along with the general regularities characteristic of Herpetic Eczema in sufficient detail the reasons of infringements of functioning of the epidermal skin barrier, which contribute to an easier penetration of the Herpes Simplex  Virus in the skin and its binding  to cellular receptors in the implementation of the infectious process. The effect of systemic and local immunity, namely, changes in T-cell and interferon system in the development of the pathological process.

The purpose of the study is to determine the features of the formation of the intestinal microbiota, its role of histamin release in children with atopic dermatitis. 110 children are surveyed: 56 — with atopic dermatitis and 54 — the healthy children. Studied the ability from intestinal microbiota to histamin release. The results of the study  — the severity of disorder of the intestinal microbiota correlated with the severity of atopic dermatitis and with unfavorable factor prenatal development. The intense of histamin release from intestinal microbiota in children  with atopic dermatitis is more pronounced than in healthy children and correlated with severity of disorder of the intestinal microbiota and with severity and stage of the disease.

Presents literary and own data (52 patients) on the role of mycoplasma infection. Mycoplasma infection is associated with long-term antigenemia in children, causes recurrent disease and autoimmunity. Among the 52 examined patients diagnosed with pneumonia in 17, bronchitis — from 19, rhinosinusitis  — at 11, StevensJohnson syndrome — in 2 children.  In half the cases mycoplasmosis occurs against the backdrop of persistent active herpes virus infection (in 27 children (52%). To optimize the causal and pathogenetic therapy mycoplasma requires correction of immune disorders.

In case of viral infections, ophthalmologists, pediatricians and general practitioners should all be aware of ocular manifestations of these diseases. According to our observations, despite the presence of corneal disorders, in 95 percent of children changes were reversible and in 1.5 months visual acuity was high. Only in five percent of cases despite the intensive therapy, patients had bacterial complications, causing a decrease in visual acuity.

The combined  efforts of infectious disease specialists and ophthalmologists as well as timely and proper treatment are required to reduce the inflammation symptoms and prevent complications. By adding Ophtalmoferon® medication to the complex therapy of ocular surface diseases we observed its high therapeutic efficacy and a good safety profile. This medication is available in the form of ready-to-use eye drops, unlike other antiviral agents, improving  its compliance in outpatients.

Analysis and examination of 220 families allowed to reveal the presence of interfamily concentration of chronic HBV-infection in 30.9% cases. The role of interdependence of the different haptoglobin (HP) phenotypes with the genotypic properties of the virus in the formation of «family cases» of chronic hepatitis В (CHB) were defined and the peculiarities of the profile of HBV markers depending on the carrier and HP viral genotype in children from family cases with CHB were discovered.

The article presents the results of research on the study of etiology, the logical structure of viral diarrhea in Baku (Azerbaijan) in 2015. It was found that more than half (62.6%), gastroenteritis in children of viral etiology, of which the leading role as an etiological factor, have a company — and adenoviruses, among infants astroviruses. But-roviral gastroenteritis and enterovirus takes only insignificant-tive percentage of cases. There were no significant differences in the proportion of virustion of diarrhea depending on the age of the patients was not revealed.
