The status of open and closed children’s institutions (nurseries, orphanages), existing personnel potential, results of communicablediseases control in Yamal (home front territory) and in Kuibyshev region (front-line territory) were analyzed. The differences in primary problems solving by Yamal and the Kuibyshev Region health authorities stood out. The key issues in Yamalo-Nenets national district were prevention of mass diseases and combating highly infectious diseases (typhus, etc.). Meanwhile, the key aspect of medical care in Kuibyshev region was to implement measures to combat the spread of gastrointestinal tract diseases and digestive disorders. Data is provided to compare the nutrition status of children in Arctic region and in Middle Volga region using these two regions’ examples. Difficulties in food supply are shown. They were quite the same despite the difference in habitat and the contingent of children (evacuated from Kuibyshev region and tundra residents). The claim that Yamal was supplied with food and industrial products with higher standards than southern regions has been questioned as archival documents have revealed the insufficient availability of products in children’s institutions 

Relevant information on Langerhans cell histiocytosis development and course in children is presented. The current concepts of disease pathogenesis, principles of its severity evaluation, patients stratification into risk groups, as well as of clinical course features are described. Modern approaches to the disease treatment via targeted therapy are summarized and analyzed. 

Computed tomography (CT) of the brain has changed diagnostic neuroradiology significantly over the past 50 years since it was firstly used back in 1971 to visualize suspected frontal lobe tumour. The safety of head CT is determined by the small amount of radiation and the low sensibility of brain tissue to cytotoxic damage due to ionizing radiation compared to other organs. However, some population groups may be at increased risk. Thus, children are more susceptible to radiation cancer than adults and lifelong attributive risk (LAR) can be more than 10 times higher for an infant than for a middle-aged adult. The authors have reviewed published studies that examined the prevalence and mortality of intracranial tumors in children undergoing head CT in comparison to unaffected individuals. Electronic search of publications in the PubMed database from 1966 to date was carried out. We have carried out intersectoral search for documents containing keywords or medical subject headings (MeSH) related to three wide categories: 1) computed tomography, 2) radiation-induced tumors, 3) risk, morbidity or epidemiology. Further search was performed in manual mode. Available epidemiological data generally confirmed correlation between head CT and tumor growth induction. Thus, current epidemiological data accept the opinion that the risk of tumor induction associated with head CT in children is very small (one tumor per 3,000–10,000 studies). The minimal estimated risk of tumor induction due to head CT in children is mostly offset by its diagnostic imaging benefits considering the clinical indications to minimize radiation dose. Understanding and quantitative risk assessment of carcinogenesis associated with CT imaging led to dose reduction in pediatric CT protocols. This trend should continue and should be implemented in all age groups. Although the decision to perform head CT is often undeniable (injury or hemorrhage), careful assessment of studies frequency is required, especially in patients who need disease monitoring. Cumulative effect in such cases may increase the minimal risk of carcinogenesis. Larger and advanced epidemiological studies are required to better understand these risks. 

Background. Despite the decrease in fetoinfantile losses, the levels of perinatal mortality and stillbirth remain quite high. One of the medical criteria for viability is the anthropometric indicators of the child, therefore, their relevant medical and statistical assessment may allow us to establish potential opportunities for reducing the loss of viable children at perinatal period.

Objective. The aim of the study is to assess anthropometric data of children died at perinatal period.

Methods. We have analyzed 277 cases of children deaths at ante- and intranatal periods and 197 cases of newborns deaths during first 7 days of life. Assessment of anthropometric data of children died at perinatal period was presented via the method of sigmal deviations and the centile method.

Results. Anthropometric data of premature infants died at perinatal period in 90–94% of cases corresponded to the physical development for children of this gestational age. Anthropometric data of full-term children died during the first 168 hours of life, in 70.0% of cases, corresponded to 3–6 corridors of physical development (P10–P90), in 20.0% of cases — 7–8 corridors. 58.3% of full-term children died at perinatal period have harmonious development which significantly exceeds the proportion of children with sharply disharmonious development (19.5%) and with disharmonious development (22.2%). 79.0% of all neonatal deaths occur in the first 72 hours of life (for the early neonatal period), while losses on the first day account for 54.0% of all deaths in children during the first week.

Conclusion. This study has shown that the anthropometric data of children died at perinatal period significantly corresponded to the standard indicators established for children of this gestation age. 

Background. The early onset of nephropathies creates certain risk of early chronic kidney disease development with loss of function (especially in children with unfavorable intrauterine period), renal tissue dysplasia, congenital malformations and/or urodynamic disorders.

Objective. The aim of the study is to evaluate the role of ontogenesis factors in nephropathies development in tender-age infants with specification of the course features and kidneys morphometric parameters.

Methods. Cohort study was conducted. The study group included 69 children aged from 0 to 36 months with changes in the kidneys (compared to age-specific ones) according to ultrasound and/or urinary syndrome (leukocyturia, bacteriuria, proteinuria, etc.). The control group included 35 relatively healthy children of the same age. Comparative analysis of antenatal and postnatal medical history was carried out in both groups, as well as comparison of morphometric indicators of the urinary system organs at neonatal ultrasound screening. Pathological process onset was also considered in the group of children with nephropathies. The study was conducted during 2018–2021.

Results. Possible predictors of pathology process in children with early onset of nephropathies are: 1) maternal diseases: urinary system disorders (OR = 4.99), blood pathology, mainly anemia of the 2nd–3rd grade (OR = 6.94), cardiovascular system diseases (OR = 10.26), inflammatory diseases of genital tract (OR = 10.61); 2) pregnancy failures: gestational diabetes mellitus (OR = 7.24), preeclampsia and eclampsia (OR = 4.40); placental pathology (OR = 17.0), and fetoplacental insufficiency (OR = 7.61); 3) feeding features: early conversion to breast-milk substitutes (OR = 2.81). 50.7% of children of this group has shown persistent urodynamic disorders already at first months of life according to ultrasound data, as well as signs of bloated kidneys. It was shown that the inflammatory process manifestation associated with aggravated perinatal history and congenital defects occurs significantly earlier — 2 months, and without any defects — 4 months (p = 0.004).

Conclusion. Burdened antenatal and neonatal medical history has negative effect on the morphogenesis of the urinary system organs and creates conditions for early nephropathies development during the first months of life. 

Background. Nowadays, population generally has high contamination with herpes virus infections. Infection commonly is asymptomatic, and the virus persists in the human body over a lifetime. Excessive diagnosis of herpes virus infections as well as overestimation of their role in the genesis of various diseases in immunocompetent people are common in Russian pediatrics.

Objective. The aim of the study is to assess the frequency and efficacy of serological testing in the suspected correlation of herpes virus infections and infectious and somatic diseases in a multidisciplinary hospital.

Methods. The study included patients hospitalized in the multidisciplinary hospital in Moscow, who were assigned serological examination for herpes viruses. The laboratory study was carried out by enzyme-linked immunosorbent assay with the revealing the markers of herpes simplex virus type 1 and 2, Epstein-Barr virus, and cytomegalovirus. The results of the examination were analyzed according to the nosology and their role in diagnosis and management.

Results. The identification of herpes virus infections’ markers was performed for 996 patients undergoing medical treatment in 17 different hospital departments within 2 months. Most commonly the examination was prescribed in infectious disease, pediatric, and hematological departments and covered more than 140 different nosologies. Acute respiratory infection, reactive arthritis, thrombocytopenia, infectious mononucleosis, acute tonsillitis, gastrointestinal pathology, acute bronchitis, and pneumonia were the most common nosologies. Positive markers of acute infection were revealed in 1.71% of cases for HSV-1/HSV-2, in 4.89% — for EBV, in 3.81% — for CMV. Moreover, positive results of serological examination were mostly noted in the cases of infectious diseases: infectious mononucleosis, tonsillitis, or acute respiratory infections. Tests were assigned for all three infections at the same time in most cases.

Conclusion. Widespread examination for herpes virus infections is the typical variant of overdiagnosis and it is usually less informative. Generally positive markers are observed in typical course of herpes virus infections when clinical picture is enough for diagnosis verification. 

Background. Patients with clubfoot can have pain and functional disorders that lead to disability. Familiarity of obstetrician-gynecologists, general practitioners, surgeons with its early diagnosis and timely management may prevent disablement.

Objective. The aim of the study is to analyze the opinion from parents of children with clubfoot on medical care via Ponseti method in outpatient center of surgery, traumatology and orthopedics.

Methods. Cross-sectional study in the form of sociological survey (questionnaire) was carried out in N.F. Filatov Children’s City Hospital from March to December 2021 among parents of children with the following diagnoses: congenital bilateral clubfoot, congenital right clubfoot, congenital left clubfoot.

Results. Respondents rated the quality of provided medical care and its availability, the hospital stay conditions by 10.0 points on the scale from 0 to 10. Territorial accessibility of medical care was estimated by 9.0 (7.0; 10.0) points, 30 out of 99 respondents (30.3%) required improvement in territorial accessibility (7 points out of 10 and below). Only 36.4% (36 out of 99) of children were sent to N.F. Filatov Children’s City Hospital for treatment by doctor of out-patient clinic. Others learned about this variant from the Internet, from acquaintances, etc. 10 out of 15 (15.2%) children with disabilities included in the study had difficulties in learning socially necessary skills. None of 10 children who have been diagnosed antenatally had any difficulties in learning socially necessary skills or disabilities. Mean age of disability was 10.6 ± 7.3 months. Children with disease diagnosed since birth had difficulties in learning socially necessary skills in 7.1% (2 out of 28) cases, and in 13.3% (8 out of 60) cases if diagnosed after birth (p = 0.356). Disability did not affect conditions in which children received treatment (14.6% and 20.0% of children under outpatient and inpatient treatment, respectively, had disabilities; p = 0.646). 26.7% of children with disabilities and only 11.9% of children without disabilities received treatment in hospital before the treatment (p = 0.218). 5.9% of children treated on outpatient basis had difficulties with learning socially necessary skills. Children treated on inpatient basis had difficulties with learning socially necessary skills in 35.7% cases (p = 0.005). The choice of outpatient or inpatient treatment did not depend on the presence of spina bifida (p = 0.276), children age (2.1 (0.7; 3.6) months vs 3.65 (0.6; 4.975) months, respectively; p = 0.309).

Conclusion. Treatment can be delayed statistically significantly in case of late diagnosis, which is associated with the observed low awareness of doctors (working by the district principle) about specialized medical care. Ratio of children with disabilities and difficulties in learning socially necessary skills or disabilities is lower among patients with antenatal diagnosis. However, further studies are required for evaluation of these factors’ association. 

Background. Chronic diarrhea can be a symptom of a wide variety of diseases, either of which requires special therapy approaches. The diagnosis of rare causes of chronic diarrhea is especially difficulty as it may be associated with inflammatory bowel disease (IBD) with very early (under 1 year of age) debut.

Clinical case description. Boy E. had chronic diarrhea manifested on the first year of life. Ulcerative colitis was diagnosed at the age of 1.5 years, then the diagnosis was changed to Crohn’s disease at the age of 2.5 years. The results of 6-years-follow-up of the patient were presented, as well as analysis of diagnosis and treatment difficulties was carried out.

Conclusion. The clinical case of Crohn’s disease with diarrhea as the leading clinical manifestation at the disease onset is described. Sequential diagnostic search allowed us to establish the diagnosis of IBD and to exclude other causes of chronic diarrhea that determined the correct therapeutic strategy. 

Congenital knee dislocation is relatively rare pathology of the musculoskeletal system. Timely diagnosis and treatment onset allow us to achieve full range of motion in the knee joint. However, low awareness of physicians in these topics and, as a result, diagnostic errors lead to pseudo-correction and motor deficit in the knee joint. This article describes correct examination of a child with congenital knee dislocation directly in the delivery room, management after discharge, and subsequent patient's routing with the assistance of orthopedic traumatologist.
