Clinical analysis of 124 cases of mycoplasma pneumoniae infection with conjunctivitis in children

Objective: To explore the distribution characteristics of symptoms and signs of respiratory mycoplasma pneumoniae infection complicated with conjunctivitis in children of different age groups. Methods: A retrospective case series study was conducted. Data of children who were treated in Beijing Children's Hospital Affiliated to Capital Medical University from September 20, 2023 to November 30, 2023, had definite mycoplasma pneumoniae infection as confirmed by mycoplasma pneumoniae nucleic acid or mycoplasma pneumoniae IgM antibody test, and had conjunctivitis as the first diagnosis in ophthalmology department were continuously collected. The included children were divided into infant group (age<4 years), preschool group (age 4 to 6 years), and school-age group (age>6 years) for analysis. Information such as the time of ocular symptoms onset, the time of systemic symptoms onset, conjunctival sac secretion, subconjunctival hemorrhage, conjunctival congestion, corneal epithelial damage, co-infection with other pathogens, and treatment of all children was collected and compared among children of different age groups. Results: During this period, there were a total of 31 133 children with positive laboratory test results for mycoplasma pneumoniae. Among them, 835 children visited the ophthalmology department during the same period, and 124 cases (229 eyes) had conjunctivitis as the first diagnosis. The age was (5.43±2.83) years, including 72 males and 52 females. There were 37 cases (69 eyes) in the infant group, 48 cases (92 eyes) in the preschool group, and 39 cases (68 eyes) in the school-age group. Among the 229 eyes, 179 eyes (78.16%) had conjunctival secretion, all manifested as mucopurulent secretion; 12 eyes (5.24%) had corneal epithelial defect; and 26 eyes (11.35%) had subconjunctival hemorrhage. There was 1 eye (1.45%) with subconjunctival hemorrhage in the infant group, 16 eyes (17.39%) in the preschool group, and 9 eyes (13.24%) in the school-age group. The proportion of subconjunctival hemorrhage in the preschool group and school-age group was higher than that in the infant group (both P<0.05). Thirty-nine cases (31.45%) were found to have co-infection with viruses in laboratory tests, including influenza A virus, adenovirus, respiratory syncytial virus, and coxsackievirus. The proportion of children in all age groups with ocular symptoms first was higher than that with systemic symptoms first. There was no statistically significant difference among children in the three age groups in terms of whether there was conjunctival secretion, whether there was corneal epithelial damage, whether there was co-infection with viruses, and the interval between ocular symptoms and systemic symptoms onset (all P>0.05). Conclusions: The characteristic ocular manifestations of children with mycoplasma pneumoniae infection complicated with conjunctivitis are conjunctival congestion and subconjunctival hemorrhage, and the signs are more obvious in preschool children. The conjunctival sac secretion of such children with conjunctivitis is mostly manifested as mucopurulent. Ocular symptoms may be the first manifestation of mycoplasma pneumoniae infection.

Margin of safety for needle puncture of a radial artery in children: Recommendation for ultrasound-guided cannulation.

The radial artery is commonly selected for arterial puncture and cannulation, but radial nerve palsy may occur. To minimize possible damage to the nerve, needle puncture should be made within the margin of safety (between the wrist to the distal end of the radial artery and the radial nerve running in parallel). In adults, the margin of safety for radial artery puncture is approximately 6.8cm from the wrist in men and approximately 5.4cm in women, but the margin of safety is not known in children of different age groups. Using an ultrasound device, we measured the margin of safety in 100 anesthetized patients aged 0months to 15yr. Polynomial quadratic regression models were made, and the lower limit of the prediction interval was regarded as the margin of safety. These results were then compared with the results obtained in adults. The margin of safety became wider as a child grows older, and the height, weight, and age were all suitable explanatory variables to predict the margin of safety, providing fairly a constant predicted margin of safety from a few millimeters in neonates to approximately 4cm in adolescents (much narrower than in adults). In children and adolescents, the margin of safety for radial artery puncture is much narrower than in adults, and these findings support the recommendation to use ultrasound guidance during radial artery puncture in children and adolescents, to minimize the risk of associated complications. jRCT1032230243.

The purpose of the study. To analyze the epidemiological situation of “childhood infections” among children under 1 year old for 2017–2021 in the Astrakhan region. Materials and methods. There were analyzed, epidemiological maps of infants with “children’s” infections as well as maps of inpatient sick infants who were treated in an infectious hospital. The results of the study. The main complaints of the majority of patients were fever — 87.8% and exanthema syndrome — 84.6%. In rare cases, patients showed catarrhal phenomena of the upper respiratory tract — 13.2%. Dyspeptic phenomena were observed in 15.9% of children. In rare cases, patients had angina — 0.5% and lymphadenopathy — 8.9%. Conjunctivitis and scleritis were observed in 9.6% of infants, including twelve cases with whooping cough, four with chickenpox and 58 with measles. The phenomena of meningitis were observed in one child — 0.1% with chickenpox. Lesions of the lower respiratory tract in the form of bronchitis — in 18.5% of infants, including two infants with chickenpox, 117 infants with whooping cough and 24 infants with measles. Research limitations. Epidemiological maps of infants with “childhood” infections identified in them were studied, during which data on the structure of the incidence of measles, scarlet fever, whooping cough and chickenpox were analyzed. Conclusions. The leading place in the incidence in infants falls on chickenpox, group outbreaks of which were repeatedly recorded over 2017 and 2018. There is a decrease in the incidence of infections such as scarlet fever and whooping cough among infants under the age of 1 year. During 2020–2021, against the background of general well-being, there is an increase in the number of cases of measles among children of different age groups, including among infants under the age of 1 year. The main complaints were fever and exanthema syndrome.

Background. Allergic rhinitis and atopic dermatitis are common allergic diseases in children. Analysis of the incidence and trends of allergic diseases development is necessary for successful solving the problem of morbidity, helping the child population at the regional level, disease forecasting and control. Purpose of the study. To study the long-term dynamics of the main epidemiological indicators of the general and primary incidence of allergic rhinitis and atopic dermatitis in the child population of the Grodno region. Material and methods. Retrospective analysis of indicators of general and primary incidence of allergic rhinitis and atopic dermatitis in the child population of the Grodno region was performed. The study periods were 1999-2023 years (children aged 0-14 years old) and 2008-2023 years (children aged 15-17 years old). Results. The average long-term age-standardized overall morbidity rate of allergic rhinitis in children aged 0-14 years old was 266.89 (95% CI: 238.33-295.47), the primary morbidity rate was 67.67 (95% CI: 57.36-77.9) per 100,000 children of the corresponding age. The average long-term overall incidence rate of allergic rhinitis in children aged 15-17 years (2008-2023) was 791.97 (95% CI: 680.79-903.14), the primary incidence rate was 113.73 (95% CI: 92.84- 134.61) per 100,000 children of the same age. The average long-term age-standardized rate of overall incidence of atopic dermatitis in children aged 0-14 years old was 872.89 (95% CI: 825.27-919.782) per 100,000 children of the corresponding age, the primary incidence rate was 459.1 (95% CI: 399. 96-518.24) per 100,000 children of the same age. The average long-term overall incidence rate of atopic dermatitis in children aged 15-17 years was 415.68 (95% CI: 377.63-453.73), the primary incidence rate was 143.88 (95% CI: 120.53-167.23) per 100,000 child population of the corresponding age. The long-term epidemic dynamics of allergic rhinitis was characterized by a moderately pronounced tendency towards an increase in the overall incidence rate among children aged 0-14 years old (average growth (decrease) rate = +2.4%) and 15-17 years old (average growth (decrease) rate = +3.62 %) as well as stabilization of the primary morbidity rate in children aged 0-14 years old (average growth (decrease) rate = -0.67%) and 15-17 years old (average growth (decrease) rate = +0.72%). The long-term epidemic dynamics of atopic dermatitis was characterized by a moderately pronounced tendency towards a decrease in the overall morbidity rate for children aged 0-14 years old (average growth (decrease) rate = -1.57%) and an increase in the morbidity rate for children of 15-17 years old (average growth (decrease) rate = +2.1%). There also was a pronounced downward trend in the primary morbidity rate of children aged 0-14 years old (average growth (decrease) rate = -5.42%) and children aged 15-17 years old (average growth (decrease) rate = -5.89%). The cartograms of the territorial distribution of incidence rates of allergic rhinitis and atopic dermatitis in the child population of the Grodno region in the periods 1999-2023 (0-14 years old) and 2008-2023 (15-17 years old) are presented. Conclusions. The reasons for the established patterns of changes in the incidence of allergic diseases in children of different age groups, as well as those living in different territories, are most likely due to the influence of environmental and socio-economic factors. The presented cartograms make it possible to visualize the incidence rates of allergic rhinitis and atopic dermatitis in individual territorial and administrative regions of the region.

Characteristics of inflammatory disease structure in the maxillofacial region among children of different age groups in Krasnodar Krai

Relevance. Acute purulent-inflammatory diseases of the maxillofacial region (APID-MFR) are the leading cause of pediatric referrals to the maxillofacial surgery department. The prevalence of APID-MFR requiring hospitalization among children in Krasnodar and Krasnodar Krai averaged 42.9% from 2017 to 2021.Objective. To investigate the nature and structure of odontogenic and non-odontogenic inflammatory processes in patients treated at the maxillofacial surgery department of the State Healthcare Institution "Children’s Regional Clinical Hospital" (CRCH), Krasnodar.Materials and methods. Medical records of patients with inflammatory diseases of the maxillofacial region, treated in the maxillofacial surgery department at CRCH, Krasnodar, from 2017 to 2021, were analyzed. The study focused on examining the structure and characteristics of the pathology in patients receiving inpatient care.Results. The most common pathology identified in children was periostitis (30.9%), which significantly differed (p = 0.007) from the second most prevalent condition, exacerbation of chronic periodontitis (26.1%). The third place was shared by lymphadenitis (13.6%) and inflammatory skin and subcutaneous tissue diseases, including boils and carbuncles (13.5%), both of which significantly differed from the top two conditions (p &lt; 0.001) but not from each other (p &gt; 0.05). In fourth, fifth, and sixth places were other inflammatory skin and subcutaneous tissue diseases: abscess (10.1%), phlegmon (4.8%), and adenophlegmon (1.0%), which also significantly differed from one another.Conclusion. The high prevalence of odontogenic APID-MFR in children highlights the insufficient prevention of caries-related complications and emphasizes the need for enhanced pediatric dental care. Early diagnosis and pre-vention of APID-MFR complications are crucial to improving outcomes in affected children.

Characteristics of early cognitive development in children with Williams syndrome: a prospective cohort study

To investigate the early cognitive development characteristics of children with Williams syndrome (WS) at different age stages. From September 2018 to June 2023, 106 children diagnosed with WS at the Department of Pediatric Health Care, Children's Hospital, Zhejiang University School of Medicine, aged 1 to <5 years, were prospectively enrolled. All children underwent Gesell developmental diagnostic assessments to analyze the cognitive development characteristics of WS children across different age groups. The average age of the 106 WS children was (3.1±1.2) years; 58 were male, and 48 were female. There were no significant differences in developmental levels between males and females in the five domains of gross motor skills, fine motor skills, language, personal-social skills, and adaptive behavior (P>0.05). The incidence rates of mild, moderate, severe, and profound developmental disabilities among children of different age groups showed no significant differences (P>0.05). Comparisons of developmental levels in gross motor skills, language, personal-social skills, and adaptive behavior among different age groups were also not statistically significant (P>0.05). With the increase of age, the developmental level of fine motor skills showed a decreasing trend (P<0.05). There were no significant differences in verbal IQ and non-verbal IQ within each age group of WS children (P>0.05). The overall developmental level of WS children stabilizes with age, and their early language abilities do not significantly exceed their non-verbal abilities.

Behavioral observation and assessment protocol for language and social-emotional development study in children aged 0–6: the Chinese baby connectome project

BackgroundThe global rise in developmental delays underscores the critical need for a thorough understanding and timely interventions during early childhood. Addressing this issue, the Chinese Baby Connectome Project (CBCP)’s behavior branch is dedicated to examining language acquisition, social-emotional development, and environmental factors affecting Chinese children. The research framework is built around three primary objectives: developing a 0–6 Child Development Assessment Toolkit, implementing an Intelligent Coding System, and investigating environmental influence.MethodsUtilizing an accelerated longitudinal design, the CBCP aims to enlist a minimum of 1000 typically developing Chinese children aged 0–6. The data collected in this branch constitutes parental questionnaires, behavioral assessments, and observational experiments to capture their developmental milestones and environmental influences holistically. The parental questionnaires will gauge children’s developmental levels in language and social-emotional domains, alongside parental mental well-being, life events, parenting stress, parenting styles, and family relationships. Behavioral assessments will involve neurofunctional developmental evaluations using tools such as the Griffiths Development Scales and Wechsler Preschool and Primary Scale of Intelligence. Additionally, the assessments will encompass measuring children’s executive functions (e.g., Head-Toe-Knee-Shoulder), social cognitive abilities (e.g., theory of mind), and language development (e.g., Early Chinese Vocabulary Test). A series of behavior observation. experiments will be conducted targeting children of different age groups, focusing primarily on aspects such as behavioral inhibition, compliance, self-control, and social-emotional regulation. To achieve the objectives, established international questionnaires will be adapted to suit local contexts and devise customized metrics for evaluating children’s language and social-emotional development; deep learning algorithms will be developed in the observational experiments to enable automated behavioral analysis; and statistical models will be built to factor in various environmental variables to comprehensively outline developmental trajectories and relationships.DiscussionThis study’s integration of diverse assessments and AI technology will offer a detailed analysis of early childhood development in China, particularly in the realms of language acquisition and social-emotional skills. The development of a comprehensive assessment toolkit and coding system will enhance our ability to understand and support the development of Chinese children, contributing significantly to the field of early childhood development research.Trial registrationThis study was registered with clinicaltrials.gov NCT05040542 on September 10, 2021.

Household job insecurity, food insufficiency, and children’s mental health needs: Household Pulse Survey in June 2023

BackgroundEconomic hardships have far-reaching implications for families with children, impacting their well-being and development during the COVID-19 pandemic. The pandemic has led to household financial problems following job loss and reduced income. As parents or caregivers face financial difficulties, children may experience emotional distress through heightened anxiety and a sense of helplessness. This study examined the effects of household job insecurity and food insufficiency due to the pandemic's aftermath on the mental well-being of children in the United States.MethodThis study utilized data from the Household Pulse Survey (HPS) during June 7–19, 2023 (Phase 3.9). The prevalence and effect of job insecurity, delineated by recent household job loss and employment status, and food insufficiency, measured through levels of food insufficiency, were analyzed across households with different age groups of children: under 5 years, 5–11 years, and 12–17 years, with an overall perspective on children under 18. We calculated unweighted observations, survey-weighted proportions, and survey-weighted 95% confidence intervals to analyze the impact of job insecurity and food insufficiency on children’s mental health treatment needs.ResultsThis study highlighted differences in economic hardships due to household job insecurity and food insufficiency across households with children in multiple age groups. There were almost twice as many respondents with no work in the last 7 days (33.68%) compared to those who experienced job loss within the last 4 weeks (14.82%). Additionally, 51.68% of respondents reported food insufficiency over the last 7 days, with more than half of the households experiencing food insufficiency due to the inability to afford more food. Mental health treatment needs among children were significantly higher in households experiencing job loss and food insufficiency. The need for mental health support for children increased with age in households facing job loss or no employment.ConclusionsThis study enhances our understanding of post-pandemic economic hardships and their influence on children’s mental health needs across different age groups. By identifying disparities and patterns, policymakers and practitioners can design targeted interventions to address employment opportunities and food access in the aftermath of the COVID-19 pandemic. Providing mental health treatments is crucial, especially for children aged 5–11 and 12–17, who are at higher risk of experiencing emotional distress due to household economic hardships.

Статистические аспекты обращений детей за стоматологической помощью при острой зубной боли.

The study analyzes the characteristics of the treatment of children with acute toothache in dental departments. The object of the study was the medical records of dental institutions in St. Petersburg. The subject of the study is the treatment of children of different age groups. The time period of the study is from 2010 to 2023. Relevance. The study of pediatric dentistry issues related to intense toothache occupies a special place in many studies. This is largely due to the age characteristics of children, who, due to their lack of development of communication skills, are not able to independently control what is happening. Analyzing applications to dental clinics, special attention should be paid to the fact that a significant part of patients are children suffering from acute toothache. This phenomenon highlights the importance of a statistical study of the causes and sequences associated with the need for dental care among the younger generation. Focusing on aspects related to children’s dental care for acute toothaches opens up access to a deep understanding of the problem and the development of strategies to overcome it. The study of statistical data can reveal certain trends, which, in turn, will help to develop more effective methods of prevention and treatment of dental diseases in children. The purpose of the study: the study of statistical aspects of children’s requests for dental care for acute toothache. Materials and methods of research: analysis of scientific and practical literature, generalization, statistical and analytical analysis. As a result of the research, a review of scientific, practical, statistical information was carried out, an empirical study was conducted, and the author’s conclusions were given. Based on the analysis, which affected the frequency of children’s visits to dental institutions, the main reasons for such visits were identified. At the top of the list are preventive measures that emphasize parents’ awareness of the importance of taking care of their child’s dental health, as well as indicating the effectiveness of educational programs in the field of dentistry. They are followed by an urgent need to consult a specialist due to severe toothache caused by a variety of causes, among which there may be diseases such as pulpitis or periodontitis. The analysis of data for the period from 2010 to 2023 revealed the immutability of the main reasons for dental office attendance and the quantitative characteristics of such requests, which confirms the constant relevance of this issue

БРОНХИАЛЬНАЯ АСТМА У ДЕТЕЙ ГРОДНЕНСКОЙ ОБЛАСТИ. РАСПРОСТРАНЕННОСЬ, ЗАБОЛЕВАЕМОСТЬ, МНОГОЛЕТНИЕ ЭПИДЕМИОЛОГИЧЕСКИЕ ТРЕНДЫ ДИНАМИКИ

Background. Bronchial asthma is the most widespread chronic nonspecific lung disease in children. Monitoring the prevalence of asthma is an important part of a set of measures aimed at preventing and effectively treating the disease. Purpose of the study. To study the long-term dynamics of the main epidemiological indicators of the overall and primary incidence of asthma in the child population of the Grodno region. Material and methods. We performed a retrospective analysis of the indicators of the overall and primary incidence of bronchial asthma in children of the Grodno region. The study period was 1999-2023 years for children aged 0-14 years and 2008-2023 years for children of 15-17 years old. Results. The long-term average standardized indicator of the overall incidence of bronchial asthma in children aged 0-14 years (1999-2023) was 597.13 (95% CI: 562.88-631.37), that of primary incidence – 79.94 (95% CI: 67.52-92.37) per 100,000 children of the corresponding age. The long-term average incidence of bronchial asthma in children aged 15-17 years (2008-2023) was 1157.69 (95% CI: 1070.69-1244.71), that of primary incidence – 44.29 (95% CI: 33.52-55.05) per 100,000 children of this age. In the age group of 0-14 years, the overall incidence of bronchial asthma was dominated by children aged 10-14 years, the primary incidence – by children of 5-9 years old. The long-term epidemic dynamics were characterized by a moderately pronounced tendency towards an increase in the standardized indicator of the overall incidence in children aged 0-14 years (average growth rate =+1.32%) and those aged 15-17 years (average growth rate =+2.87%), stabilization of the indicator of primary morbidity in children of 0-14 years old (average rate of decline = -0.49%) and a downward trend in the rate of primary morbidity (average rate of decline = -3.48%) in children aged 15-17 years. The levels and average long-term trends in the dynamics of indicators in individual territorial and administrative districts of the region have been established. The trends in the dynamics of asthma incidence rates in the administrative territories of the region during the analyzed period were multidirectional and had varying degrees of stability. The cartograms of the territorial distribution of bronchial asthma incidence rates in children of the Grodno region in the periods 1999-2023 (0-14 years) and 2008-2023 (15-17 years) are presented. Conclusions. The reasons for the established patterns in changes in the incidence of bronchial asthma in children of different age groups and those living in different territories require further study.

Analysis of the epidemic characteristics of common respiratory pathogens infection in children in a 3A special hospital

ObjectiveTo analyze the epidemic characteristics of common respiratory tract infection pathogens in children with respiratory tract infection, and provide scientific basis for the prevention and control of respiratory tract infection.MethodsA retrospective collection of clinical data was conducted on 11,538 children with respiratory tract infections at Luoyang Maternal and Child Health Hospital from December 2022 to November 2023. The types of respiratory tract infections, including upper and lower respiratory tract infections, as well as five respiratory pathogens: influenza A virus (influenza A), influenza B virus (influenza B virus, adenovirus (ADV), respiratory syncytial virus (RSV), and Mycoplasma pneumoniae (MP) infections, were analyzed and compared for different genders, ages, temperatures, and air quality in different months; And the changes of five pathogens in children with respiratory tract infections of different disease severity.ResultsFrom December 2022 to November 2023, a total of 11,538 children with respiratory infections were included in the analysis, including 6436 males and 5102 females, with an age of 4.92 ± 2.03 years. The proportion of upper respiratory tract infections is as high as 72.17%, and lower respiratory tract infections account for 27.83%. Among them, 2387 were positive for Flu A antigen, with a positive rate of 20.69%, 51 cases were positive for Flu B antigen, and the positive rate was 0.4%, 1296 cases were positive for adv antigen, with a positive rate of 11.23%, 868 cases were positive for RSV antigen, with a positive rate of 7.52%, 2481 cases were positive for MP IgM antibody or MP antigen, and the positive rate was 21.50%. Flu B in male children The infection rate of ADV and MP was higher than that of female children (p < 0.05); Among children in different age groups, the older the age, the older the Flu A The higher the infection rate of MP (p < 0.05), the higher the positive rate of RSV in children with younger age (p < 0.05). The positive rate of ADV in children aged 3–6 years and > 6 years was higher than that in children aged 0–3 years (p < 0.05); Flu A and MP are popular throughout the year, and the positive rate peaks during the period of temperature rise and air quality decline from February to March, and during the period of temperature drop and air quality index rise from August to November, The positive rate of RSV peaked after the turning point of temperature rise from March to April. The infection rate was higher during the period of sharp decline in air quality from March to May and sharp decline in temperature in November, The positive rate of ADV was higher at the turning point of temperature rise from February to March, and then the infection rate decreased. During the period of sharp temperature drop from August to November, the positive rate increased sharply, and the peak of infection occurred; As the disease worsens, The positive rates of Flu A, Flu B, RSV, MP and combined infection with more than two pathogens were all increased (p < 0.05).ConclusionAfter the new coronavirus epidemic in 2022, Flu A and MP have the highest infection rate of respiratory pathogens in children, showing a peak growth in general, with epidemic characteristics changing with environmental temperature, air quality and seasons. The main disease type is upper respiratory tract infection, MP and adv infections were mainly in male children, Flu A, MP and ADV infections are more common in older children, RSV infection was more common in younger children; Flu A, Flu B, RSV and MP infection and the co infection of more than two pathogens may more easily lead to the occurrence of severe pneumonia.

Age-related Variation in Sleep-dependent Obstruction in Surgically Naive Children.

Little is known about age-related variations in sites and grade of sleep-dependent airway obstruction in children with obstructive sleep apnea (OSA) or obstructive sleep-disordered breathing (oSDB). The objective was to compare sites and grade of obstruction on drug-induced sleep endoscopy (DISE) across different age groups of surgically naïve children with OSA or oSDB. A retrospective chart review was performed for surgically naïve children aged 0-18 years with OSA/oSDB who underwent DISE from July 2021 to August 2023. Participants were categorized into: infants (aged 0-1 years), younger toddlers (aged 1-2 years), older toddlers (aged 2-3 years), preschool (aged 3-5 years), younger school-aged (aged 5-10 years), and older school-aged (aged 10-18 years). On DISE, obstruction was rated 0 = none/mild, 1 = moderate, 2 = severe for inferior turbinates, adenoid, velum, palatine tonsils/lateral pharyngeal wall, lingual tonsils, tongue base, epiglottis, and supra-arytenoid tissue. A series of multiple regression analyses were used to identify age differences in the grade of obstruction across all sites combined and at each individual site separately. The sample consisted of 252 children aged 1 month to 17 years with 57.9% males. Older patients had greater total obstruction scores (B = 0.42, SE = 0.10, p < 0.01) and greater number of sites that were severely obstructed (B = 0.11, SE = 0.05, p = 0.03). Older age groups had more obstruction at inferior turbinates (p = 0.02), adenoid (p < 0.01), palatine tonsils/lateral pharyngeal wall (p < 0.01), lingual tonsil (p < 0.01), and base of tongue (p < 0.01). Younger age groups had more obstruction at the supra-arytenoid tissue (p < 0.01). Varying patterns of sleep-dependent airway obstruction should be expected across different age groups in children with OSA or oSDB. 3 Laryngoscope, 2024.

Early-onset scoliosis in children aged 4-7 years in Nanjing, China: A cross-sectional study.

This study aimed to investigate the potential variance in the prevalence of early-onset scoliosis among children aged 4-7 years and analyze the influencing factors. The goal was to establish a crucial reference point for monitoring and evaluating spinal curvature development in preschoolers, ultimately to reduce the occurrence of adverse health outcomes. Children aged 4-7 years within the main urban area of Nanjing were selected using a stratified random sampling method. A team of four senior therapists conducted screenings for spinal curvature among children using visual inspection, the Adams forward bending test, and an electronic scoliometer to measure the angle of trunk rotation (ATR) and identify children displaying signs of scoliosis. Children with suspected scoliosis in the initial screening underwent X-ray Cobb angle assessment for confirmation. The prevalence of early-onset scoliosis was then determined from the screening results. R version 4.2.0 software was used to analyze the factors associated with scoliosis among children using partial least squares structural equation modeling. A total of 2281 children were included in this study, consisting of 1211 boys and 1070 girls, with a mean age of 5.44 ± 0.81 years (ranging from 4 to 7 years). Among them, 7.58% exhibited positive signs of scoliosis, 5.87% had early-onset scoliosis, and the positive predictive value was 77.5%. Significant differences in ATR were observed among children in different age groups (Kruskal-Wallis = 15, p = 0.0104) and by sex (t = 3.17, p = 0.00153). Significant variations in ATR were noted in children with scoliosis (t = -22.7, p < 0.001), with a cutoff at ATR = 4.5°, and auxiliary values of 0.947 and 0.990. Children diagnosed with early-onset scoliosis generally exhibited lower body mass index values, with a statistically significant difference (t = 2.99, p = 0.003). Using visual inspection, the Adams test, and an electronic scoliometer to measure the ATR, the present triad method is more sensitive for early scoliosis screening in children with abnormal posture aged 4-7 years. A full spine X-ray is advised in children with an ATR over 4.5° and poor posture.

Surveying adult support for child and youth voice on environmental governmental decision-making in Australia and New Zealand

The global movement of student strikes for climate action illustrates that many children and youth want to have a voice on governmental decisions on the environment. Yet in most nations, an electoral voice is not granted to those under the age of 18. From prior research, we see the main barrier for child and youth voice to parliament is adult attitudes towards children and youth. To find out who supports their voice on government decisions for the environment, we added such a question to the Australia and New Zealand iterations of the International Social Survey Program 2020 survey. The results indicated that the majority of surveyed adults support 11–14 year olds (Aus 62 %, NZ 59 %) and 15–18 year olds (Aus 79 %, NZ 80 %) having opportunities to influence government decisions on the environment. Analysis of responses to this question in relation to demographic survey data indicated variations in preferences for different age groups of children and youth, and that age, gender, education, concern for the environment, environment organisation membership and prior election political party preference of respondents were variables of significance for both nations. Recommendations for policy and practice to broaden support for child and youth voice to contribute to government decisions on the environment are suggested with application of Iris Marion Young’s propositions for more inclusive democracy.

Epidemiological characteristics of fatal drowning and related factors in children in Zhejiang Province, 2022

Objective: To understand the epidemiological characteristics of fatal drowning in children in Zhejiang Province in 2022, analyze factors such as the swimming ability of children, the caregiver behavior at drowning site, types of first aid personnel and methods of first aid of unintentional fatal drowning and provide evidence for targeted intervention. Methods: Using the "Survey Form of Fatal Drowning Case in Children" designed by National Center for Chronic and Non-communicable Disease Control and Prevention of the China CDC, we collected case information of children aged 0-17 years who died due to drowning in Zhejiang in 2022 from medical history/death investigation records, telephone interviews, and home visits. Results: A total of 341 fatal drowning cases in children occurred in Zhejiang in 2022 and 330 cases were investigated (96.77%). The male to female of the cases was 2.33∶1, most cases were aged 15-17 years and 0-4 years, and 54.24% of fatal drowning cases occurred in children from other provinces. In the drowning cases, 83.33% were unintentional ones, and the proportion of intentional fatal drowning cases in children increased with age. Fatal drowning cases mainly occurred in open natural water bodies and public water storage facilities. More fatal drowning cases occurred in open natural water bodies in older children, while more fatal drowning cases occurred in public water storage facilities in younger children. In 275 children who died due to unintentional drowning, 73.09% could not swim, and only 1.09% were fully supervised by adults within an arm's length. First aid personnel, mainly medical staffs, bystanders and adult caregivers, were present for 47.63% fatal drowning cases. The proportion of the cases who had cardiopulmonary resuscitation as the first aid within 5 minutes was 2.18%. Conclusions: Drowning poses a serious threat to children's lives and there are differences in reasons and locations of fatal drowning in children in different age groups in Zhejiang Province in 2022. It is necessary to conduct to interventions to improve children's swimming skills, strengthen effective adult care and conduct health education about field first aid of drowning to reduce the incidence of drowning and related deaths in children.

PARAMETERS OF THE INTERCONDYLAR FOSSA OF THE FEMUR IN CHILDRENIN NORMAL CONDITIONS AND WITH CONGENITAL MALFORMATIONS OF THE LOWER LIMBS

According to literature sources, radiography can indirectly visualize congenital insufficiency of the cruciate ligaments both in isolated form and in combination with other congenital malformations of the lower extremities. Objective. To study the parameters of the intercondylar fossa of the femur in children of different age groups with stable/unstable knee jo ints due to congenital malformations of the lower limbs using instrumental imaging methods. Methods. A prospective diagnostic study was conducted of 359 knee joints of 217 children who were treated at the pediatric orthopedics clinic from 2019to 2022 and with a retrospective control group (2010–2021). limbs, as well as with congenital malformations of the lower limbs. X-ray examinations were performed on the OPERA T90cex X-ray and fluoroscopic system. Results. 217 patients took part in the study, including 105 patients without knee jointpathology and 112 with congenital malformations of the lower limbs. Comparison of the accuracy of radiological diagnostic indicators was performed using the Studentʼs t-test with the results of computer and magnetic resonance imaging studies, which showed the absence of a statistically significant differencein the results research. A diagnostic study was also conducted to find the regularity of the development of the knee joints and to identify the parameters of the radiological norm of the development of the intercondylar fossa of the femur in children of different age categories. Conclusions. Using the resultsof instrumental studies, the parameters of the intercondylar fossa of the femur in children of different age categories with stable and unstable knee joints due to congenital malformations of the lower limbs were investigated. The results of the study should be taken into account for the diagnosis of congenital defects of the knee joint.

Estimating Effective Diameter and Scan Length of Abdomen and Pelvis for Radiation Dose Optimization in Computed Tomography Imaging Suitable for the Indian Population – A Preliminary Study

Abstract Background: Utilization of computed tomography (CT) has dramatically increased during the last decade with a concurrent increase in exposure to ionizing radiation. Even low levels of exposure have been linked to the development of cancer. Various dose reduction and optimization techniques have been attempted to minimize the risk. Dose optimization becomes crucial when scanning thin and small-built individuals, particularly children. Reference phantoms of European or North American descent are used to develop radiological protocols. CT dose index (CTDI) metrics like scan length, volume CTDI, and dose-length product help to measure the amount of radiation dose received by patients during CT scans. Methodolgy: We studied the anatomical dimensions of the CT abdomen and pelvis from the topographic and tomographic images using the standard bony landmarks in 340 children and 500 adults (F = 250, M = 250) and. Cross-sectional measurements and effective diameter were also used to generate CT phantom models. Results: Using measured variables, phantom models have been generated in different age groups in children and adults representative of the Indian population showing a significant increase in dimensions from pediatric to adult phantom. Dimensions vary from classic reference phantoms of European or North American descent. Conclusion: Diagnostic reference levels must be adjusted according to the age of the patient, size of organs, or surface area of examination as body proportions vary between age groups, sex, and race. Data from this study can be used to generate the age- and sex-specific preset protocols for dose optimization in the adult Indian and pediatric population to minimize exposure risk, particularly in young children.
