This article refutes one popular-science review that has appeared on the MDedge news site in January 2020. It has stated that there was no effect of vaccination with 7-valent pneumococcal conjugate vaccine (PCV-7) against invasive forms of Streptococcus pneumoniae in children with bronchial asthma. The author of this publication refers to the article «Asthma and the Risk of Invasive Pneumococcal Disease: A Meta-analysis» that described episodes of invasive pneumococcal disease and pneumonia development in children with bronchial asthma and in healthy children who was vaccinated with pneumococcal conjugate vaccine. It was concluded that the PCV-7 provides limited protection against colonization only with vaccine pneumococcus serotypes (according to the obtained data), and, thus, there was high risk of carriage of non-included serotypes in children with bronchial asthma (BA). The analysis of the article mentioned above has revealed that the representativeness of the data is extremely low. For example, the study groups were selected incorrectly, the PCV-7 administration scheme was not analyzed, whereas its violation may cause ineffective immunity development and as result disease development. Another crucial aspect is the lack of any data on the BA severity and inhaled corticosteroid therapy in vaccinated children. Nowadays, there are numerous scientific studies on the clinical efficacy of PCV in the prevention of IPD including the children with BA. Most world-class experts support the necessity of PCV-7 usage in children with BA for the prevention of IPD and suggest their patients over 6 years old on inhaled corticosteroid therapy to perform additional administration of pneumococcal polysaccharide vaccine.

Background. Development of thrombotic complications in the postoperative period worsens the course of the disease and increases mortality of children operated for congenital heart diseases (CDC). There is limited data on clinical risk factors of thrombosis after CDCs surgical correction in modern literature. In our opinion, there are several promising factors that have not been studied as predictors of thrombosis in children with CDCs. Aim of the study is to analyze possible effect of patient clinical characteristics on development of thrombotic complications in infants after surgical treatment of CDC. Methods. We have studied data of 156 children aged from birth to 11 months 29 days (median age — 5 months) with CDCs operated under artificial circulation. Following indexes were studied in all patients: age, surgical risk according to RACHS-1 (Risk adjustment for congenital heart surgery), anesthesia duration, surgery duration, aortic cross-clamping time, artificial circulation duration, gestation period, body weight and height at the time of surgery. Results. Thrombosis was diagnosed in 44 patients (28.2%) in the postoperative period. Thromboses of various localizations were found during the patients’ examination: cerebral, intracardiac, limbs vessels, etc. It was revealed that thrombosis detection in patients with RACHS-1 >3 has increased in 2.84 times (95% CI: 1.36-5.92), at anesthesia duration >220 minutes — in 2.64 times (95% CI: 1.15-6.05), at surgery duration >150 minutes — in 3.36 times (95% MD: 1.51-7.5), at aortic cross-clamping time >32 minutes – in 3.23 times (95% CI: 1.45-7.32), at artificial circulation duration >70 minutes — in 3.43 times (95% MD: 1.6-7.34), with gestation period less than 39 weeks — in 2.44 times (95% CI: 1.18-5.03), with child’s weight less than 5.000 grams – in 4.3 times (95% CI: 2.02-9.15), with child’s height less than 60 centimeters — in 4.57 times (95% CI: 2.15-9.73), and at the age less than 3 months old — in 2.31 times (95% CI: 1.08-4.92). Conclusion. RACHS-1 >3, anesthesia duration >220 minutes, surgery duration >150 minutes, aortic cross-clamping time >32 minutes, artificial circulation duration >70 minutes, gestation period less than 39 weeks, weight at the time of surgery less than 5000 grams, height at the time of surgery less than 60 centimeters, and age under 3 months increases the risk of thrombotic complications in postoperative period.

Background. Many social problems have worsened nowadays especially in the context of the COVID-19 pandemic. It is important that child health professionals have all the necessary knowledge for detection of child abuse in modern society. Aim of the study is to study the awareness and competence of pediatricians on child abuse. Methods. The cross-sectional study was conducted using the international standardized questionnaire (22 questions). The study has included practicing pediatricians from inpatient and outpatient (95% of all respondents) clinics in Kazan. Results. The data from questionnaire survey of 73 pediatricians has shown that 29 (40%) and 39 (53%) of all respondents encountered physical and psychological abuse against children, respectively. Physical abuse was considered as the most common form of abuse by 38 (52%) pediatricians. The child abuse was revealed during routine examination in 33 (45%) cases. 20 (28%) respondents have initiated proceedings for every case of physical abuse, and 23 (31%) — for psychological abuse. One in three pediatricians, 23 (31%), consider the present legislation comprehensive enough in the sphere of children protection against abuse. Meanwhile, 50 (68%) pediatricians regarded their own level of awareness in this topic as insufficient. Conclusion. The study has shown insufficient competence of pediatricians (especially in the visiting services) in the detection and maintenance of children abuse cases (physical and psychological). It is crucial to enhance and continuously improve education of pediatricians on pre-graduate and continuing professional education levels in issues of children abuse.

Background. The severity of thrombosis clinical course, poor prognosis, upcoming disability and permanent organ failure in newborns necessitate further search and study of thrombotic conditions predictors in order to prevent them. Aim of the study is to analyze the frequency of gene variants of plasmic, thrombocytic and fibrinolytic hemostasis components and determine their role in the thrombosis development in newborn children. Methods. The study included 46 full-term newborns with thromboses of different localization – cases group. Inclusion criteria were: child age 28 days or less, gestational period >37 weeks, informed consent on participation in the study. The control group included children of I and II health groups. Vascular thrombosis was diagnosed via instrumental imaging methods: vascular ultrasound, computer tomography, magnetic resonance imaging. Thrombophilic anamnesis and pregnant woman’s health condition was analyzed according to pregnancy medical records. The molecular genetic testing included 8 single nucleotide polymorphisms definition of the following genes: FGB -455 G>A (rs1800790), F2 20210 G>A (rs1799963), F5 1691 G>A (rs6025), F7 10976 G>A (rs6046), F13 G>T (rs5985), ITGA2 807 C>T (rs1126643), ITGB3 1565 T>C (rs5918), PAI-1 -675 5G>4G (rs1799889). Results. Molecular genetic predictors of thrombosis in newborns have been revealed: variants of fibrinogen gene FGB -455 G>А (AP, %=66), plasminogen activator inhibitor gene PAI-1 -675 4G > 4G (AP, % = 89), genotype associations PAI-1 -675 4G/>4G /F7 10976 G>G (AP, % = 82), PAI-1 -675 4G>4G / F13 34 G>G (AP, % = 63)PAI-1 -675 4G>4G / F7 10976 G>G / F13 34 G>G(AP, % = 61), and integrin alpha 2 gene ITGA2 807 T/T (AP, % = 93). Maternal factor of thrombosis development in children is impaired uteroplacental circulation in pregnant woman (AP, % = 66). Conclusion. The role of gene variants of plasmic, thrombocytic and fibrinolytic hemostasis components in development of thrombosis in newborns was determined, as well as quantitative estimation of their contribution was presented.

Acute gastroenteritis is an infectious disease, often with viral etiology, which can include diarrhea (three or more loose or liquid stools in 24 hours) and the possible presence of vomiting and fever. This pathology is common disease for any pediatrician in his practice. Currently, many specialists use a variety of different guidelines and approaches to the treatment of acute gastroenteritis, thus not all of them meet the criteria of evidence-based medicine. This review presents contemporary approaches to the pharmacotherapy of acute gastroenteritis based on world experience and guidelines from developed countries. This review also covers the issues of specific prevention of rotavirus infection and the role of vaccination in prevention of certain somatic diseases.

The official history of the International Pediatric Association begins on July 28, 1910, when its Charter was adopted at the meeting of the French Pediatric Association. This significant event was preceded by the years of professor I.V. Troitsky promotion of such idea as “science does not have any fatherland because the whole world belongs to it”. He has encouraged pediatricians from all countries of the world for the joint work with regular discussion of the results. Professor I.V. Troitsky has developed the Charter and has defined the goal and objectives of the future International Pediatric Association, largely determining the further evolution of pediatric science.

Background. This clinical case of orphan disease can be interesting for its early diagnostics which is essential for timely specific therapy and sufficient dynamic observation. Clinical case description. Mucopolysaccharidosis type II (Hunter syndrome) diagnosis at the age of 12 months was based on common external manifestations, recurrent otitis and isolated osteoarticular system lesions without any other systems decompensations. The awareness of doctors about the disease criteria and its diagnostics algorithm, as well as the availability of laboratory testing on lysosomal enzyme iduronate-2-sulfatase (I2S) activity are crucial for early diagnosis. The patient has undergone molecular genetic testing: mutations in the IDS gene encoding iduronate-2-sulfatase were revealed. The enzyme replacement therapy with idursulfase according to the protocol has been started. Patient’s condition has improved on the therapy (after 4 months of the therapy): stable neuropsychic development (no delay), increased large joints flexibility, reduced hepatosplenomegaly, and no hearing loss. Conclusion. Timely diagnostics of mucopolysaccharidosis allows to start enzyme replacement therapy early and significantly ease the disease course despite the severe congenital defect in the glycosaminoglycans metabolism.

Background. Type II mucolipidosis (I-cell disease, ICD) is one of the lysosomal storage diseases. It is very rare disease; the literature describes only few cases with confirmed diagnosis of mucolipidosis. Cardiovascular changes in children with such pathology are even less often. Clinical case description. The article describes the clinical case of type II mucolipidosis alongside with cardiovascular pathology — valvular heart apparatus defect with abdominal aortic hypoplasia and reversible myocardial dysfunction on the therapy of chronic heart failure (CHF). The patient has coarse face, gingival hyperplasia, macroglossia, dysostosis multiplex, diffuse muscular hypotonia, and mass of subcutaneous tissue. Arterial hypertension, heart cavities dilatation, left ventricular (LV) walls hypertrophy, and data of CT aortography let us to diagnosis abdominal aortic hypoplasia. Conclusion. Cardiovascular malformation in patients with mucolipidosis leads to severe, life-threatening conditions development. Untimely diagnosis can worsen the course of disease. Multidisciplinary approach is needed for the patient management.
