Ultrasound-guided thoracic paravertebral block in a premature neonate with congenital oesophageal atresia with a tracheo-oesophageal fistula: a case report

Ultrasound-guided thoracic paravertebral block (TPVB) is a promising new technique for use in children of various ages. In this case report, a successful ultrasound (USG) guided TPVB procedure in premature neonate is described. A 3-day-old 1600-g neonate, born at 32 weeks of gestation, was underwent thoracostomy for esophageal atresia with esophageal fistula repair. At the end of the surgery, USG-guided TPVB were successfully performed using a linear probe in the paramedian position. USG-guided TPVB could be an alternative method for providing effective analgesia in a premature neonates in the future.

Understanding disease symptoms and impacts and producing qualitatively-derived severity stages for MPS IIIA: a mixed methods approach

BackgroundMPS IIIA is a rare, degenerative pediatric genetic disease characterized by symptoms impacting cognition, mobility and behavior; the mean age of death is around 15 years of age. Currently, there are no approved therapies for MPS IIIA.MethodsA two-year, multi-center, prospective, descriptive cohort study was conducted to document the natural history course of MPS IIIA. In the context of this study, semi-structured interviews were performed with parents of children at study entry and one year later. Interview transcripts were analyzed using thematic analysis methods to identity concepts of interest to children and parents, identify what factors impacted parents’ burden the most, and develop qualitatively-derived disease severity stages. Children were sorted into these stages according to the symptoms their parents described at the entry interview. This sorting was compared quantitatively to the sorting of children at baseline according to the child’s calendar age and their BSID development quotient (DQ).Results22 parents in France, Germany, the Netherlands and the UK were interviewed. Children ranged in age from 28 to 105 months (mean 61.4 months). The conceptual models for children’s symptoms and impacts and parents’ impacts provided a detailed and comprehensive picture of what it is like for children of various ages and their parents to live with MPS IIIA. Four factors were identified as mediating the burden perceived by parents: state support, family support, time since diagnosis, and parent coping strategy. Four disease stages were developed, accounting for both the presence and the severity of MPS IIIA symptoms. The comparison of children’s sorting into these stages with the BSID DQ and the child’s calendar age showed strong statistical associations.ConclusionsThe findings of this qualitative research embedded in a natural history study add to the current understanding of MPS IIIA as a complex disease that impacts every aspect of the lives of children and their families. This study demonstrates the unique potential of mixed methods research in rare diseases to address some of the current limitations of more traditional quantitative approaches by providing an individualized, detailed understanding of the patient experience.

Seroprevalence of IgG and IgM antibodies to Haemophilus influenzae type a in Canadian children

BackgroundOver the last 2 decades, Haemophilus influenzae type a (Hia) has emerged as a significant cause of invasive disease in some geographic regions and populations. Recognition of the importance of Hia in the etiology of serious disease, particularly in young children, prompted the development of a new protein-capsular polysaccharide conjugate vaccine, similar in design to a vaccine against H. influenzae type b. At present, understanding of Hia immunology is incomplete; the immunological correlate of protection against invasive disease is unknown. MethodsOur objective was to study Hia antibody in children of various ages residing in a Canadian province with low incidence rates of invasive disease. The enzyme-linked immunosorbent assays were performed to quantify plasma IgG and IgM specific to Hia capsular polysaccharide in 133 children (3 months to 16 years). ResultsBoth anti-Hia IgG and IgM concentrations increased with age and were significantly higher in older children; a positive correlation between age and concentrations of Hia antibody was found. IgM antibody concentrations were significantly higher than IgG, with mean IgM concentrations over 10 times larger than IgG across all age groups. ConclusionsThe steady rise of naturally acquired, Hia-specific IgG and IgM concentrations in a pediatric population with low incidence rates of invasive Hia disease suggests the exposure to some cross-reactive environmental antigens as a major source of the antibody. However, the carriage rates of Hia in the region are unknown and further seroepidemiological studies are warranted. Although natural antibody may protect certain population groups against invasive disease, immunization of younger children will be essential to prevent serious infections if Hia continues to spread across North America.

ANATOMICAL RATIONALE FOR CHOOSING A BLADE FOR POWER-ASSISTED ADENOIDECTOMY IN CHILDREN DEPENDING ON DENTITION.

The aim: To study the anatomic features of the facial skull structures in children of various ages depending on dentition. Materials and methods: One hundred and forty-four children aged 2-12 years were divided into 4 groups depending on dentition. They underwent anthropometric measure¬ments during adenoidectomy. Based on the cosine theorem, the calculated values were obtained. Results: The distance from choana to the free edge of the retracted soft palate gradually increases from 2.01±0.61 cm in children with stable primary dentition up to 3.09±1.02 cm with mixed dentition. Palato-nasopharyngeal angle in children with stable primary dentition is 126.25±8.76°, in children with aging primary dentition - 132.81±12.21°, and in children with mixed dentition - 120.54±13.72°. Conclusions: The optimal configuration of the blade for power-assisted adenoidectomy in children with stable primary dentition has an angle of 53.53±8.76°, and the length of the working part of 2.01±0.61 cm, in children with aging primary dentition - 47.18±12.21° and 2.10±0.71 cm, with mixed dentition - 59.45±13.72° and 3.09±1.02 cm, respectively.

Dental caries prevention program in children and adolescents living in residential institutions

Was to assess the effectiveness of a new dental caries prevention program in children of various ages living in residential institutions. The program of oral health promotion and caries prevention was introduced in the autonomous non-profit organization «Social rehabilitation center Solba». The study comprised 98 children aged 12-17 years divided into two groups: the main group of 52 children aged 12-16 years enrolled in the program in 2013 in pre-school (32 children) and primary school age (20 children) and the control group of 46 adolescents aged 12-17 years not included in the program. DMFT and OHI-S index were compared in both groups as well as in children enrolled in the program at various ages. The overall caries prevalence was 84.7%. Statistically significant differences were documented between children enrolled in the program in pre-school and primary school ages regarding both caries prevalence (78% and 89%, respectively) and intensity (3.5 and 5.4 tooth, respectively (p=0.01)). Non-satisfactory, poor and very poor OHI-S was observed in 15.4% of children in the main group and 54.3% of controls. Good oral hygiene was seen in 67.3 and 37%, satisfactory - in 17.3 and 8.7% of children, respectively (p<0.05). Programs of dental caries prevention with oral health promotion component are effective for oral hygiene improvement in children living in residential institutions. The key for long-term effectiveness and dental caries prevalence and intensity reduction is the start of the program in pre-school age and education of caregivers and teachers to provide control of dental care in pre-school and primary school children.

The Effect of Mother’s Education on Sexual Education of Preschool Children Based on Health Belief Model

Aims: Nowadays the necessity of informing children of various ages about sexual issues is felt more than ever before. The present study has been conducted to determine the effect of the mothers’ education on the preschool children’s sexual training based on the health belief model. Methods: the present study is experimental intervention research performed on 144 mothers with preschool children in 2020 in Sanandaj. The participants were randomly selected from 12 preschools by multi-stage cluster sampling method. The intervention was conducted through the use of a combination of in-person and remote training according to the constructs of the health belief model. The data were collected by the use of a researcher-constructed questionnaire the validity and reliability of which have been assessed and confirmed and subsequently analyzed using SPSS, version 23, through the descriptive and analytical statistics, including chi-square tests, fisher’s exact test and t-test, one-way variance analysis, and LSD follow-up test and Kolmogorov-Smirnov test. Findings: the study results indicated that the mean values of the scores calculated for knowledge and perceived susceptibility constructs, perceived barriers, cues to action, and perceived self-efficacy in the intervention group’s mothers following training were significantly higher than those of the control group (p<0.05). Conclusions: the results of this study showed that 3 training sessions with the design of health belief model structures in mothers are effective in performing sexual education of children.

Multisystemic inflammatory syndrome in children associated with covid - 19. A case Report

Pediatric inflammatory multisystem syndrome (PIMS) associated with asymptomatic COVID-19 has been reported in children of various ages from infancy onwards. The dominant symptoms of PIMS are fever above 38.5 C lasting more than three days, elevated inflammatory markers, and the occurrence of symptoms from at least two systems; the digestive system and the cardiovascular system. Early diagnosis and treatment improve prognosis and may reduce life-threatening complications. We present a case of a 7-month-old infant hospitalized in the Department of Infectious Diseases and Child Neurology in Poznan.

THYMUS SONOMETRY AND RECURRENT RESPIRATORY INFECTIONS IN PRESCHOOL CHIKDREN

Introduction. The results of scientific research that have been received so far in terms of the relationship between health status of children of various age and thymus size are controversial. On the one hand, researchers mainly from the former Soviet Union note the presence of the clear association between thymomegaly and an increased tendency to recurrent respiratory infections among preschool children. On the other hand, according to current data of world medical science, a relatively larger thymus, on the contrary, is considered to be the sign of the optimal state of child's immune system. The study aimed at clarifying of the interdependence between the thymus physical parameters and the frequency of acute respiratory infections in children aged 1-6 years. Materials and Methods. Thirty-seven children (16 boys and 21 girls) aged from one to six years, undergoing inpatient treatment on acute respiratory infection, were involved in the clinical study. Two markers of acute respiratory infections recurrence (infections index, resistance index) were taken into account and several anthropometric parameters were calculated for each child. The participants also underwent ultrasound scan. The statistical processing of the obtained primary digital material was performed by IBM SPSS Statistics 26 licensed program. Results. The thymus size was within the reference values only in 14 (37.84%) examined children. In the majority of the patients (23 (62.16%)), it was below the mentioned values. The significant exceeding the thymic index values in the children of the younger age group as compared with the older children was found. There was no difference between the boys and girls in terms of thymus volume, mass and thymic index. Conclusions. There is а moderately pronounced inverse relationship between the age of the examined children and the thymic index, according to which this index values are decreased with increasing age. The integral indicators of acute respiratory infections recurrence among the preschool children are not correlated with the studied absolute and relative sonometric thymus parameters. The thymic index values are in the closest and inverse correlation with the body surface area among all the anthropometric parameters considered in the children.

Pulmonary hypertension in children with chronic bronchopulmonary pathology: a pulmonologist’s perspective to the problem

The respiratory diseases are consistently ranked first in the morbidity pattern among children and adolescents in the Russian Federation. Registry data show that 10-12% of children with pulmonary hypertension have PH-associated chronic lung pathology. Pulmonary hypertension as a life-threatening complication of such chronic lung diseases as hypersensitive pneumonitis, bronchiectasis, bronchial asthma, etc. aggravates the severity of their clinical course and has a great impact on the outcome of the disease. The article summarizes modern data on pulmonary hypertension in children of various ages associated with chronic bronchopulmonary pathology. The issues of classification, pathogenetic mechanisms, criteria and modern methods of diagnosis and treatment, as well as prognosis are considered. The authors come to the conclusion that despite the in-depth study of the pathogenetic aspects of the development of pulmonary hypertension in chronic bronchopulmonary pathology in children, which has recently made it possible to shed light on the understanding of many of its aspects, it should be admitted that the problem as a whole is far from being resolved. Early detection and treatment of pulmonary hemodynamic pathology is extremely important to prevent the formation of cor pulmonale. Pulmonary hypertension, which complicates the chronic lung diseases, is still incurable and is associated with high mortality. Now, young patients with pulmonary hypertension are still often examined and treated using guidelines for adult patients. However, differences in etiology, clinical presentations and diagnostic capabilities require a special approach to studying this problem in children, which raises the question of the need to develop separate clinical guidelines for pediatric practice.

ROLE OF PARENTAL, SCHOOL AND PEER GROUPS IN PREVENTION OF SUBSTANCE ABUSE

This research is an attempt to assess the role of parents, schools, and peer groups in substance abuse prevention. Substance misuse is more common in persons, particularly children, who believe they are ignored by others, are excluded from their peer groups, and have no one with whom to discuss their problems. Such children utilise escapism to escape from all of life's worries by immersing themselves in a completely fictional yet lovely world. This world, on the other hand, is a fleeting pleasure that can cost one's life. The direct and indirect effects of alcohol and other drugs on children can result in a variety of negative health and safety consequences for the kid, family, and community. Understanding the dangers and how to avoid them A first step toward alleviating the problem of drug use in the paediatric population is to identify factors that may influence the development of substance dependence. This page analyses the literature on substance abuse prediction, protection, and prevention in children, as well as a list of available preventative programmes for children of various ages. The earlier a youngster begins drinking and using other drugs, the greater the chance of catastrophic health repercussions and adult substance misuse. Accidental and purposeful deaths connected with adolescent drug and alcohol use are one of the main preventable causes of death in the 15- to 24-year-old demographic. Adolescents who use alcohol or other drugs have an increased risk of academic underachievement, delinquency, teenage pregnancy, and depression. Multiple medical consequences have resulted from inadvertent passive drug exposure in infants and toddlers, including respiratory infections, seizures, changed mental status, and death. There are numerous factors that lead to the formation of substance misuse in children. Prevention and intervention programmes that use research-based, comprehensive, culturally relevant social resistance skills training and normative education in an active school-based learning format can address behavioral, emotional, and environmental factors that put children at risk for substance abuse.

Peningkatan Pengetahuan dan Kemampuan Kader Posyandu dalam Stimulasi I Ntervensi dan Deteksi Dini Tumbuh Kembang Anak di Kelurahan Hadimulyo Barat Kota Metro

The golden period of growth and development of children occurs from the beginning of pregnancy until birth and children are 2 years or 1000 days. The impact of children not being stimulated can be growth disorders and delays. The problem of delays or deviations in child development is still a problem for children in Indonesia. The role of cadres needs to be increased to stimulate early detection and early intervention of developmental deviations. This activity aims to improve the knowledge and skills of cadres in early stimulation and intervention for growth and development, so as to be able to find early developmental deviations in toddlers. This activity uses a training method with education using modules and simulations using a developmental pre-screening questionnaire. The participants of the activity were the Melati Cadre and Kenanga Cadre totaling 14 people and 19 infants under five in the West Hadimulyo sub-district, Metro Central district, Metro city. Evaluation of activities was carried out by pre-test and post-test and assessment of the skills of cadres to stimulate development using developmental pre-screening questionnaires. The results of the activity obtained increased knowledge and skills of Integrated Service Post cadres to stimulate development with a developmental pre-screening questionnaire. The enthusiasm of the cadres in this activity and the support of partners, so that the activity can be smooth and successful. It is necessary to follow up the implementation of cadre skills directly during early stimulation activities and interventions for the growth and development of children of various ages

Prevalence of Epstein-Barr Viral DNA among children at a single hospital in Suzhou, China

ObjectiveThis study aimed to describe the prevalence of Epstein-Barr virus (EBV)-DNA among children in Suzhou, and to explore the association between plasma EBV load and disease diagnosis. MethodsAll children admitted to the Children's Hospital of Soochow University between January 2018 and September 2020 and subjected to the plasma EBV-DNA assay were included. The authors retrospectively collected demographic and discharge diagnostic information of the participants, and ascribed the disease distribution characteristics of children with positive plasma EBV-DNA by age and viral load. ResultsA total of 38,175 patients underwent plasma EBV-DNA PCR assay, of which 2786 (7.3%) had EBV-DNA in their plasma. Children aged 3–4 years had a high prevalence of EBV infection. Plasma EBV positivity was common with infectious mononucleosis (IM, 40.0%), respiratory infection (20.1%), atypical EBV infection (14.2%), acute leukemia (6.4%), hemophagocytic lymphohistiocytosis (HLH, 4.8%), and idiopathic thrombocytopenic purpura (ITP, 2.9%). With increasing age, plasma EBV positivity was more common in children with IM and atypical EBV infection. However, an inverse correlation was observed in children with respiratory infections and ITP. High levels of EBV loads were more likely to occur in HLH, IM, and atypical EBV infection, especially in HLH. However, lower viral loads were found in respiratory infection and acute leukemia. ConclusionsThis is a large sample study that revealed the prevalence of plasma EBV-DNA levels in children of various ages and presenting illnesses.

Adverse and Protective Childhood Experiences and Parenting Attitudes: the Role of Cumulative Protection in Understanding Resilience.

Theory and research indicate that adverse childhood experiences (ACEs) are linked to negative parenting attitudes and behaviors. We posit that protective and compensatory experiences (PACEs) in childhood buffer the negative effects of ACEs on later parenting. To test this premise, the present study examined associations between ACEs, PACEs, and attitudes towards nurturing and harsh parenting in an ethnically diverse sample of parents with children of various ages (N = 109; 65% mothers, 35% fathers; M age = 38). Parents completed a widely used parenting attitudes questionnaire and the ACEs and PACEs surveys. PACEs were negatively correlated with ACEs and positively correlated with nurturing parenting attitudes and parent income and education levels. Linear regression models indicate that higher PACEs, ACEs, and family income and less harsh parenting attitudes predict nurturing parenting attitudes. In contrast, higher ACEs and less nurturing attitudes were correlated with harsh parenting attitudes. As expected, moderation analyses indicated that the association between ACEs and harsh parenting attitudes was conditional upon the level of PACEs. When PACE scores were low (M – 1 SD), but not when PACE scores were average or high (M + 1 SD), ACEs were associated with harsh parenting attitudes, suggesting a buffering effect of PACEs on negative parenting attitudes. These findings support the importance of including protective as well as adverse childhood experiences when assessing the role of childhood experiences on parenting attitudes and practices. Implications of these findings for researchers and practitioners are discussed, as well as new directions for PACEs research using a cumulative protection approach.

Internalizing and externalizing problems in preschool children: The role of mothers' and fathers' observed parenting behavior in a well-resourced sample.

Empirical evidence links sensitive parenting behavior to positive developmental trajectories in children, whereas parental intrusiveness, in contrast, has been found to increase the risk of socio-emotional problems in children of various ages. However, most studies investigating the effect of parenting behavior have been conducted with mothers. Thus, little is yet known about fathers' role in child development and if mothers' and fathers' parenting behaviors are linked to child socio-emotional outcomes in similar or different ways. To date, findings are ambiguous, and this is why more studies are needed. The present study examined associations between mothers' and fathers' observed sensitivity and intrusiveness and children's internalizing and externalizing problems as reported by parents and by children themselves. The sample compromised 52 mothers, 41 fathers and their preschool children. Results from hierarchical regression analyses showed a negative association between fathers' intrusiveness, at low levels, and children's internalizing problems. This result was unexpected. However, in line with this finding, a number of recent studies suggest that when fathers challenge and push their children's limits, it buffers against emotional problems such as anxiety. The present study highlights the importance of a continuous investigation into fathers' potentially unique contribution to children's socio-emotional development. No other associations were identified between mothers' and fathers' parenting behaviors and children's internalizing and externalizing problems. Most likely, because this study was conducted with a low-risk sample, where children were in general well-functioning.

Spinal anaesthesia applications in pediatric subabdominal operations

Introduction: Spinal anesthesia is increasing in pediatric patients; 14 children of various ages who were operated for lower abdominal diseases were treated retrospectively. Cases: Intraoperative vital signs were stable. Hypotension and bradycardia were not observed generally; 0.5mg atropine was administered in only 1 patient. Heart rate and blood pressure were monitored from the monitor. The sensory dermatomal level was below thoracal 8. Postop pain, nausea, vomiting, itching, and tremor headache were not observed. Patient satisfaction and surgeon satisfaction were evaluated as very good. The patient had no tension or fear. The surgeon was not forced during the operation due to muscle spasm and the operation was successful. Intraoperative pulse, tension, mean arterial pressure, sp02 were noted; at least 73/min, 100/50.75mmhg, 97 respectively. All of the patients were discharged without complications. No serious side effects such as cardiovascular collapse, total spinal block, neurological damage, intravascular injection associated with spinal anesthesia were encountered. It is very important to use a safe, rapid-onset and effective anesthesia method in pediatric surgical procedures, where intraoperative pulmonary and cardiovascular stability is preserved and stress response is suppressed and effective postoperative analgesia is provided.

Children helping to co-construct a digital tool that is designed to increase children’s participation in child welfare investigations in Sweden

How do children (aged 6–12 years) understand and make use of a digital tool that is under development? This article builds on an ongoing interdisciplinary research project in which children, social workers (the inventers of this social innovation) and researchers together develop an interactive digital tool (application) to strengthen children’s participation during the planning and process of welfare assessments. Departing from social constructionism, and using a discursive narrative approach with visual ethnography, the aim of the article is to display how the children co-construct the application and contribute with “stories of life situations” by drawing themselves as characters and the places they frequent. The findings show that the children improved the application by suggesting more affordances so that they could better create themselves/others, by discovering bugs, and by showing how it could appeal to children of various ages. The application helped the children to start communicating and bonding when creating themselves in detail, drawing places/characters and describing events associated with them, and sharing small life stories. The application can help children and social workers to connect and facilitate children’s participation by allowing them to focus on their own perspectives when drawing and sharing stories.

Development of acetabular anteversion in children with normal hips and those with developmental dysplasia of the hip: a cross-sectional study using magnetic resonance imaging

Background and purpose — Acetabular anteversion (AA) is related to hip function. Most previous studies were based on radiographic investigations that determine osseous acetabular anteversion (OAA). But children’s acetabulum is mostly composed of cartilage; the cartilaginous acetabular anteversion (CAA) represents the real anteversion of the acetabulum. We measured OAA and CAA in children of various ages using MRI, and compared the developmental patterns between children with normal hips and those with developmental dysplasia of the hip (DDH). Patients and methods — The OAA and CAA were measured on MRI cross-sections of the hips in 293 children with normal hips (average age 8 years), and in 196 children with DDH (average age 34 months). Developmental patterns of OAA and CAA in children with normal hips were determined through age-based cross-sectional analysis. Differences in OAA and CAA between children with normal hips and those with DDH were compared. Results — Normal OAA increased from mean 8.7° (SD 3.2) to 12° (3.0) during the first 2 years of life and remained unchanged until 9 years of age. From 9 to 16 years, the OAA showed a minimal increase of 2°–3°. The normal CAA increased rapidly from a mean of 12° (3.1) to 15° (2.7) within the first 2 years of life, and remained constant at 15° (SD 3.4) until 16 years of age. The age-matched average OAA in the normal and DDH cases was 11° (3.2) and 15° (3.0), respectively (p < 0.001). The age-matched average CAA in normal and DDH cases was 17° (4.2) and 23° (4.5), respectively (p < 0.001). Similarly, there was a significant difference in OAA and CAA between the uninvolved hips in unilateral DDH and normal cases (p < 0.001). Interpretation — The CAA was fully formed at birth in normal children, and remained unchanged until adulthood, whereas the OAA increased with age. The OAA and CAA were both over-anteverted in DDH children. MRI evaluation is of importance in children during skeletal development when planning hip surgery.

INTERNET ELECTROCARDIOGRAPHY IN PEDIATRICS

&lt;b&gt;Introduction.&lt;/b&gt; Internet electrocardiography (internet-ECG) is becoming one of the most deman-ded areas of telemedicine; it becomes especially important in conditions of remoteness from medical and diagnostic institutions and impossibility of real consulting assistance of specialists. The general principle of operation of the internet-ECG devices is transferring the record to a server with subsequent processing and obtaining an automatic conclusion on the rhythm and morphology of the atrial-ventricular complex. At present, internet-ECG is widely used in adult network, while its possibilities in pediatrics are poorly covered. &lt;br&gt;&lt;b&gt;Materials and methods.&lt;/b&gt; The archive of children's ECGs recorded using the Cardiometer-MT system in the period from 2013 to 2021 has been analyzed. 3 groups of children were identified. 1&lt;sup&gt;st&lt;/sup&gt; - screening of practically healthy children of primary school age (2153 children), 2&lt;sup&gt;nd&lt;/sup&gt; group - school-age children examined in children's city polyclinics, who underwent stress and vegetative tests (2500 children), 3&lt;sup&gt;rd&lt;/sup&gt; group - 200 healthy full-term newborn children who had a standard resting ECG on 1-2 days of life. &lt;br&gt;&lt;b&gt;Results.&lt;/b&gt; The advantages of using such systems in the mass examination of children of various ages in the framework of screening programs are shown. The results of an ECG examination of 2153 healthy children of primary school age are presented. The results of the automatic and medical conclusion are compared, sensitivity and specificity in the detection of cardiac arrhythmias and conduction are determined. The advantages of internet-ECG in carrying out vegetative and stress tests in the examination of adolescent children are substantiated. Performance of functional (including vegetative) and stress tests using internet-ECG systems allows to estimate reliably the functional state of the cardiovascular system, to determine adaptive capabilities of the vegetative nervous system, to reveal hypertension at early stages. &lt;br&gt;&lt;b&gt;Conclusion.&lt;/b&gt; The internet-ECG makes it possible to significantly simplify and streamline the ECG examination of children, forming an electronic archive of records, which is relevant for field exa-minations in children's groups and in conditions of a shortage of qualified specialists in functional diagnostics.
