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.","PeriodicalId":10867,"journal":{"name":"Current pediatrics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75847217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":10867,"journal":{"name":"Current pediatrics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88964942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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).

Participants are secondary school students of the 8th–11th grades. Digital activity was examined via online survey among adolescents. We took into account the use of social media, information search, watching videos on the Internet, using of messengers, playing games with electronic devices. Cognitive features (memory, thinking, executive functions, sensory information procession, reading and speech, understanding of emotions, decision-making) and emotional state of adolescents (anxiety) were evaluated by clinical psychologists via various tests. School performance was determined by the recent results of the school quarters/semester finished by the time of the survey. Social and age factors included regular out-of-school physical activity and family structure (complete/ incomplete).Results. We have examined 438 teenagers. 53 (12%) respondents spend more than 5 hours a day with digital devices on weekdays, 133 (30%) — on weekends, 147 (34%) — during the holidays. Structure of digital activity during weekdays (≥ 1 hour) among adolescents was the following: activity in social media prevailed (63.5% of respondents), fewer teenagers searched for information or watched videos on the Internet (47.3 and 42.9%, respectively), about a third (34.9%) played via electronic devices. Structure of digital activity changed over the weekend and during the holidays. We have revealed differences between the information search activity and the volume of short-time memory, understanding the verbal messages, and verbal-logical operations level. Adolescents with different levels of computer gaming activity have shown diversity in sensomotor reaction speed, visuospatial memorization accuracy, number of errors in high-speed reading, reading pace, and understanding text basic meaning.Conclusion.

This disease is characterized by multisystem involvement and chronic progressive course.Clinical case description. The clinical case attracted our attention due to the late disease diagnosis in a boy living in a metropolis. The child has classic clinical manifestations of the disease: typical phenotype, spinal deformity, developmental speech and motor delays, hearing loss, hepatomegaly, splenomegaly, umbilical and inguinal hernias. Despite developmental speech delay and frequent recurrent otitis, the patient has not been referred to surdologist examination until the age of 4.5 years. Intriguing fact is the presence of congenital cataract that was the reason for surgery twice.Conclusion. Congenital cataract is one of the early manifestation of this disease. 3 out of 8 patients with alfa-mannosidosis observed in our centre had congenital cataract. We assume that such patients should be referred to genetics for the early exclusion of alpha-mannosidosis. Late diagnosis and progressive course of the disease led to early disability of the patient.

Onasemnogene abeparvovec is the first gene replacement therapy medication based on the adeno-associated viral vector (AAV9). One injection to a patient with 5q spinal muscular atrophy (SMA) leads to replacement of the missing or defective SMN1 gene with its functional copy. It leads to normalization of survival motor neuron protein (SMN) production.Objective. The aim of the study is to evaluate efficacy, safety, and causes of different responses to therapy after single administration of onasemnogene abeparvovec in 5 patients with 5q SMA (types I and II) comparing the baseline status with the results of continued monitoring in real clinical practice in Russian Federation.Methods. Interim results of continued follow-up of children with 5q SMA with 2–3 copies of the SMN2 gene are presented: 2 boys and 1 girl with type I who received single dose of onasemnogene abeparvovec at 4 and 7 months of age; and 2 girls with type II who received therapy at 11 and 16 months of age.Results. Short-term controlled fever was observed in 4 out of 5 patients during first 2 weeks after viral vector therapy administration (max in patient 5 — up to 38.5 ° C). All 5 children had transaminases increase,  1 patient — significant transaminases increase during the sensitisation period (> 10 from upper normal level (UNL)), 1 patient — delayed significant transaminases increase (> 20 UNL), 1 patient — transaminases increase (> 3 UNL) after discontinuation of longterm therapy with glucocorticosteroids (according to prescribing information). All patients had shown positive and sustained response to therapy over time at motor status assessment via CHOP INTEND / HFMSE scales. The more significant response was observed in patients with less aggressive baseline 5q SMA type II with 3 copies of the SMN2 gene.Conclusion. Onasemnogene abeparvovec is relatively safe medication for management of children with 5q SMA.

Differential diagnosis of attenuated forms of mucopolysaccharidosis (MPS) and juvenile idiopathic arthritis (JIA) can be challenging due to their similarities.Objective. The aim of the study is to create simple diagnostic criteria (DScore) that would allow to differentiate MPS from JIA for earlier MPS diagnosis.Methods. The retrospective multicenter study included analysis of clinical (joint, heart, eye involvement, hearing loss, hernias, psychomotor delay, noisy breathing, posture disorders, macrocephaly, hepatomegaly, splenomegaly, and growth delay) and laboratory data (ESR, CRP, hemoglobin, WBC, and platelets) from MPS patients (n = 41) and from rheumatoid factor-negative polyarticular category of JIA patients (n = 255). These variables allowed to differentiate both conditions and were used to create DScore.Results. Patients with MPS had younger onset age, male predominance, height and weight delay, lower inflammation markers (WBC, platelets, and ESR), and usually involved joints, especially cervical spine, upper limbs joints, hip, and small foot joints. The prevalence of eye involvement was similar for both diseases, however, the type of involvement was different. JIA patients had uveitis and its’ complications and MPS patients — corneal opacity and cataract. No differences in CRP levels were revealed in most cases. The major diagnostic criterion of MPS was the presence of more than one extra-articular manifestation associated with polyarticular involvement. DScore has included 5 following criteria: ESR ≤ 11 mm/h (38 points), height ≤ -2.0 SD (20 points), onset age of articular manifestations ≤ 1.1 year (24 points), male gender (15 points), and symmetrical limitation of movements in elbow joints (29 points). The sum > 38 points allowed us to differentiate MPS and JIA with sensitivity of 92.7% and specificity of 91.0%.Conclusion.

Patients with MPS IVA look healthy at birth, however, they develop typical spine deformities (kyphoscoliosis), pectus carinatum, wrists hypermobility with decreased muscle strength and loss of fine motor skills, valgus deformation of lower limbs during the first years of life. Pathological changes in cardiovascular and respiratory systems, visual and acoustic analyzers can be revealed. Early diagnosis of the disease is crucial for timely initiation of enzyme replacement therapy. Thus, low incidence of the disease and its heterogeneous clinical picture complicates diagnosis. Consequently, patients with MAS IVA often become severely disabled as early as adolescence.
