Objective: to study the relationship of the main mediators of atopy and clinical and morphological characteristics lesions of the stomach with its secretory-motor disorders in children with atopic dermatitis. We study 134 patients aged 7 to 14 years with atopic dermatitis and 30 healthy children as control group. All children passed general clinical and laboratory instrumental investigations. In addition, children with manifestations of atopic dermatitis and secretory-motor disorders of the stomach Fibroesophagogastroduodenoscopy, topographic intragastric pH-metry with aspiration biopsy of the gastric mucosa were performed, followed by morphological investigations. In sick children, an increase in the levels of total IgE, histamine and serotonin was detected in the blood, combined with a tendency to decrease acid-forming function, endoscopic and morphological changes in the gastric mucosa. It is assumed that concomitant atopic dermatitis secretory-motor disorders of the stomach are manifestations of gastrointestinal syndrome, which can be both secondary and primary in relation to skin manifestations and in both situations contribute the formation of endoallergens and maintain a vicious cycle of the pathological process.

Background. In children with spondylolisthesis, there are still unexplained aspects in the relationship of the degree of displacement of the L5 vertebra with the severity of the clinical picture and neurological disorders. At the same time, aspects of the mutual aggravating influence of the indicated spinal disorder on the condition of the feet have not been studied. Therefore, the problem of identifying disorder of foot function in children with spinal spondylolisthesis of the L5 vertebra is relevant.Aim of the study — to evaluate the deviations in parameters of the transverse and longitudinal arches of feet in children suffering from severe spondylolisthesis of the L5 vertebra.Materials and Methods. In the period from 2016 to 2018, 12 children aged 14.1 y.o. [12,7; 15,5] were examined with spondylolisthesis of the L5 vertebral body of grade III-IV, accompanied by stenosis of the spinal canal at the same level and by compression of the roots of the spinal cord. Imaging diagnostics included multispiral computed tomography (MSCT) and magnetic resonance imaging (MRI). To estimate the function of the feet, double-bearing and single-bearing plantography was used. The data for the control group included only plantographic examinations of 12 healthy children of the same age.Results. In patients with spondylolisthesis, the mean value of the anterior t and intermediate s plantographic bearing indices were significantly lower than those of healthy children. At the same time, in tests with an increased load on the foot in patients, there was no significant increase in the mean anterior t and medial m indices, which indicates the dynamic rigidity of the transverse and medial longitudinal arches. The value of the lateral plantographic index l showed its significant pathological increase compared with the normal value at double-bearing load, which indicates the static rigidity of the lateral longitudinal arch. Correlation analysis demonstrated that, against the normal state, the bearing ability of the feet in sick children is realized through a pathological strengthening of the functional relationship between the arches of the foot at double-bearing load and a non-physiological reduction of the interaction between arches at single-bearing load.Conclusion. In children with severe forms of vertebra spondylolisthesis, the parameters of plantographic characteristics indicate the rigidity of the arches of the feet and the distortion of their bearing pattern. It is necessary to take into account the aggravating effect of rigid feet on the state of the spine and include the examination of the bearing function of the feet in the algorithm for the comprehensive diagnosis of children with spondylolisthesis.

THE AIM. To determine the concentration of natriuretic peptide in the blood serum in children with congenital malformations of the urinary system (CM US) and to compare with the activity of renin-angiotensin-aldosterone system (RAAS).MATERIALS AND METHODS.119 patients with CM US aged 3 to 18 years were examined. A control group of 10 clinically healthy children. 3 groups were assigned: group I – 55 children with  congenital vesicoureteral reflux, and group II – 34 children with  congenital hydronephrosis and ureterohydronephrosis, III group – 30 children with other forms of dysembryogenesis of the US. Following indicators were identified by ELISA in the blood: renin, aldosterone,  N – terminal propeptide natriuretic hormone (NT-рroВNР). RESULTS.NT-рroВNР, renin and aldosterone hyperproduction were diagnosed in 59,6%, 69,7%, 54.6 % of sick children relatively. Concentrations were higher in all variants of  malformations in comparison with the control group. Significant  differences were revealed in obstructive species, where arterial  hypertension (AH) was diagnosed more often. Patients with AH  recorded significantly higher concentrations of NT-proВNР and renin.CONCLUSION.The key point in pathological processes developmentand progression in the cardiovascular system and kidneys is the  activation of RAAS. The system of natriuretic factors is important in maintaining the compensated state of patients due to the blockade of RAAS.

The article presents data on the long-term effect (nine months) of a silicon compound supplied with drinking water – nonahydrate sodium metasilicate (10 mg/l in terms of silicon), on CD68-positive macrophages in the liver and spleen of laboratory rats. Changes in the morphological characteristics of this cell population were found. There was a decrease in the average cell area (in the liver of the control group of rats, the average macrophage area was 179.23±5.94 microns2, and in the group receiving silicon with drinking water – 117.04±3.35 microns2; in the spleen-136.02±3.93 microns2 and 103.44±2.8 microns2, respectively). Macrophages in the liver preparations of the experimental group of rats had a fewer processes and a darker cytoplasmic membrane. The number of macrophages in the liver per unit area was comparable, for the control group of rats it was 18.78±1.24, and for the rats that received with water with the addition of silicon – 19.41±0.75 cells. CD68+ macrophages of the red splenic pulp in laboratory rats that received silicon also underwent the following morphological changes: they were located in a denser way and had fewer processes, while the number of macrophages per unit area was 73.7±2.3 for the control group, 91.6±5.0-for the experimental group, respectively. The distance between them did not change. There was a change in the intensity of CD68 expression on the surface of the cytoplasmic membrane and in the cytoplasm of liver and spleen macrophages. These changes can be interpreted as the adaptive ability of liver and spleen macrophages to silicon introduced with drinking water. Given the heterogeneity of the macrophage population in the liver and spleen, further studies using markers for different subpopulations of macrophages are needed to clarify their role in the response of tissues to silicon supplied with drinking water.

AbstractBackground:Abnormalities in the hippocampus have been implicated in the pathophysiology of psychosis. However, it is still unclear whether certain abnormalities are a pre-existing vulnerability factor, a sign of disease progression or a consequence of environmental factors. We hypothesized that first-episode psychosis patients who progress to schizophrenia after one year of follow up will display greater volumetric and morphological changes from the very beginning of the disorder.Methods:We studied the hippocampus of 41 patients with a first-episode psychosis and 41 matched healthy controls. MRI was performed at the time of the inclusion in the study. After one year, the whole sample was reevaluated and divided in two groups depending on the diagnoses (schizophrenia vs. non-schizophrenia).Results:Patients who progressed to schizophrenia showed a significantly smaller left hippocampus volume than control group and no-schizophrenia group (F = 3.54; df = 2, 77; P = 0.03). We also found significant differences in the morphology of the anterior hippocampus (CA1) of patients with first-episode psychosis who developed schizophrenia compared with patients who did not.Conclusions:These results are consistent with the assumption of hyperfunctioning dopaminergic cortico-subcortical circuits in schizophrenia, which might be related with an alteration of subcortical structures, such as the hippocampus, along the course of the disease. According with these results, hippocampus abnormalities may serve as a prognostic marker of clinical outcome in patients with a first-episode psychosis.

The results of genetic studies have proven the relationship of celiac disease with class II genes of the major histocompatibility complex (HLA), in particular with the DQ locus. The presence of specific alleles at the HLA-DQ locus is necessary, but insufficient, for the realization of the disease phenotype. In Uzbekistan, the distribution of HLA markers in children with celiac disease has not been studied and these studies are required. Purpose — to establish the peculiarities of the distribution of HLA II class celiac disease alleles in children in the Uzbek population. Materials and methods. We examined 54 children with celiac disease of the Uzbek population, who were registered and receiving inpatient treatment at the Republican Specialized Scientific and Practical Medical Center of Pediatrics. The age of the examined children was from 1 to 14 years old, the average age was 7.3±1.9 years. The control group consisted of 109 unrelated Uzbeks without immune diseases. Molecular typing of HLA II class genes was determined by DNA chain reaction polymerase. Results. As a result of gene typing, 48 (88.8%) out of 54 investigated had DQ2 and DQ8 haplotypes associated with celiac disease. Haplotypes with only DQ2 and DQ8 were found in 19 (39.5%) and 7 (14.5%), respectively. DQ2 from 48 children was found in 18 (37.5%) children in the trans-position, in 2 (4,1%) — as two copies of DQ2 dimers, and in 1 (2%) case in combination with DQ8. Only in one case (2%) was DQ8 found as two copies of DQ8 dimers. The frequency of occurrence of the HLA-DRB1*07 and *13 alleles was significantly higher than in the control group. The maximum value of the relative risk and the criterion of reliability are noted in the DQA1*0501 allele, i.e. it is positively associated with celiac disease (χ2=7.28, RR=2.03). Significance criterion and relative risk were observed in sick children with DQB1*0201 (χ2=6.74, RR=1.97) associated with celiac disease. The number of haplotype (DQA1*0501-DQB1*0201) was 36 (75%). Conclusions. A specific predisposition to celiac disease in children of the Uzbek population is associated with the genes HLA-DQA1*0501, HLA-DQB1*0201, HLA-DRB1*07 and *13. Alleles such as DRB1*15, DQA1*0102, DQB1*0303 and *0502, have a protective effect in the development of celiac disease in children of the Uzbek population. A high frequency of carriage of the DRB1*13 — HLA-DQА1*0501 and DQB1*0201 (DQ2 type) haplotype in Uzbeks (75%) was found, which requires a more thorough population genetic study of the Uzbek population for the HLA II class DRB1-DQA1-DQB1 genes. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: celiac disease, children, genetics, HLA class II.

Objective: to study the clinical neuropsychiatric and neuropsychological features of children suffering from systemic somatovegetative disorders.Materials and methods: the study involved children from 5 to 12 years old with an established diagnosis of bronchial asthma — 108 children; atopic dermatitis — 105 children; gastroesophageal reflux disease — 112 children; the control group consisted of 60 same age healthy children. All children underwent clinical-anamnestic, neurological, psychopathological and neuropsychological research.Results: the children with systemic somatovegetative disorders have a significantly high incidence of pathogenic factors of central nervous system damage in early stages of ontogenesis (pathology of pregnancy and childbirth). Early sensory and motor deprivation due to somatic suffering aggravates neuropsychiatric deficiency. Neuropsychological disorders were predominantly represented by a violation of the perception of their body, lack of kinesthetic and motor functions, spatial and quasi-spatial representations.Conclusion: the clinical dynamics of neuropsychiatric disorders in children with systemic somatovegetative disorders corresponds to the dynamics of residual cerebral organic impairment with a stage-age changes of syndromes. The revealed neuropsychological disorders correspond to preferential damage to the first (energy) functional block of the brain.

Objective: Acute bronchiolitis is one of the most common causes of hospitalization for children younger than 1 year. Although the prognosis for these children is generally good, the condition involves a risk of mortality. Here, we evaluate the immature platelet fraction (IPF) as a biomarker for the severity of acute bronchiolitis. Material and Methods: In total, 179 children who had been diagnosed with acute bronchiolitis were classified into three groups: mild, moderate, and severe bronchiolitis, and 80 healthy children were included as a control group. The diagnostic capacity of the IPF, mean platelet volume (MPV), platelet distribution width (PDW), white blood cell count (WBC), and platelet count (PLT) values to predict bronchiolitis was evaluated using receiver operating characteristic (ROC) curves and their respective areas under the curves (AUCs) calculated with 95% confidence intervals. Results: Patients with acute bronchiolitis had a larger IPF than their healthy counterparts (p < 0.001). Additionally, a positive correlation was observed between the clinical severity of the disease and the IPF. The ROC curve analysis indicated that the IPF cut-off point for predicting acute bronchiolitis was >3.2%, with a sensitivity of 84% and specificity of 97%. Our results clearly demonstrate that the AUCs for IPF, MPV, PDW, WBC, and PLT were statistically significant for the bronchiolitis versus the control group. The AUC was greatest for the IPF. Conclusion: The IPF is a new marker for diagnosing and evaluating the clinical severity of acute bronchiolitis.

Background. Atopic dermatitis (AD) is the most common allergic disease among children of young age. Severe forms of AD with skin bacterial and fungal overgrowth may be associated with features of the immune response in different age groups. Plenty of studies demonstrated not only polarization of the Th2 immune response in AD patients, but also the Th1 immune dysregulation. The purpose of this study was to investigate the features of the immune response in children with varying severity of atopic dermatitis. Materials and methods. The study included 85 children aged 3 months to 3 years with a verified diagnosis of AD, living in the Zaporozhzhia region. Twenty healthy children without atopy formed a control group. The patients were divided into groups depending on the severity of AD based on the SCORAD scale. The serum levels C3, C4–2, CD3+, CD19–, CD4+, CD8–, CD4–, CD8+, CD3–, CD56+, CD19+, CD14, CD45, IgA, IgM, IgG, IgE, С3, С4–2, phagocytic acti­vity of neutrophils, and proliferative activity of lymphocytes were measured by flow cyto­metry (Synevo). ELISA method was used to detect serum levels of IL-13 (ELISA Kit, Thermo Fisher Scientific, Austria). Statistical processing of the results was performed using the official software package Statistica 13.0. Results. The study revealed eosinophilia in 60 % of the children with a mild and moderate course of AD (Me 5.62 [3.64; 7.81]) and in 56 % of the children with a severe course (Me 6.18 [3.13; 9.42]). The children with a severe course of AD and low levels of IL-13, C3 had transient hypogammaglobulinemia and significantly lower le­vels of the C3 complement, increased levels of CD4+, CD8– with simultaneously decreased levels of CD4–, CD8+ compared with groups of the children with high levels of ­IL-13 (р < 0.05). Conclusion. The results suggest that severe forms of AD in children of the young age were associated with changes in the complement system and low levels of cytotoxic cells, transient hypogammaglobulinemia. It requires deeper research of the cascades of the immune response in children with AD.

The paper presents research results of patho-morphological effects of extremely low frequency rotating magnetic fields and pulsed traveling magnetic fields on the kidneys of mammals from the perspective of in-formation theory. The study was conducted in four experimental groups and one control group, each of which consisted of 15 adult mice line S/Bl6. The following information characteristics were determined for all groups: information capacity, i.e. the maximum structural diversity of functional systems, information entropy, information organization, information relative entropy and the coefficient of relative organization of the system. Analysis of the values of information characteristics have allowed to establish that the lowest values of information entropy and maximum values of the coefficient of relative organization of the system were obtained in the groups with the most severe pathological changes. This indicates the formation of stable equilibrium as the norm, and in terms of irreversible pathological process. The results of the correlation analysis in all groups showed that the highest accuracy of prediction have regression model for relative information entropy, obtained in the control group and in group 2, in which severe pathological changes didn’t observed.

Nasal Cytology

The aim of this study was to evaluate the cytological picture of nasal mucosa in children with atopic diseases and to determine the diagnostic value of the test for the diagnosis of atopic diseases. The study included 140 children from 4 months to 17 years old. Among children with a history of atopy, there were 30 children with atopic dermatitis, 30 children with asthma, and 46 children with allergic rhinitis. The control group consisted of 34 healthy children. The nasal scraping technique has been used to collect samples from the nasal cavity. The samples were evaluated under light microscope. Epithelial cells as well as infiltrating cells were assessed. The only statistically significant group of cells differentiating children with atopic disease and without atopy were eosinophils, which in children with atopy were significantly more common. Assuming a significant eosinophilia value of at least 5% of all cells in cytogram, the sensitivity of nasal cytology in allergic rhinitis was 52.2%, in asthma 33.3%, and in atopic dermatitis 13.3%. The specificity of the test in atopic diseases was 94.1%. It can be concluded that nasal cytology with eosinophilia assessment can be a useful tool for an early diagnosis of atopic disease in children.
