Do toys get in the way? The duration of shared emotional experiences is longer when mothers engage their infants without toys

During mother-infant interaction, shared emotional experiences, defined as reciprocal and synchronous emotional sharing between mother and infant, are an indicator of early relational health. Yet, it is unclear how mothers' efforts to engage with their infants relate to dyadic-level shared emotional experiences. Utilizing a sample of 80 randomly selected videos of the NICHD Study of Early Child Care and Youth Development, we examined how mothers' bids for interaction with their 6-month-old infants related to the duration of shared emotional experiences. An event sampling, sequential coding system was used to identify a maternal bid for interaction (i.e., with toy, without toy) and the subsequent presence or absence of a shared emotional experience, including duration of the shared emotional experience. Results indicated that shared emotional experiences were longer following mothers' efforts to engage their infants in play without toys. Findings suggest that methods matter; researchers and practitioners interested in studying and promoting shared emotional experiences between mothers and infants may wish to focus on dyadic interactions without toys.

Association between Contextual Factors and Affordances in the Home Environment of Infants Exposed to Poverty

Home environments of infants exposed to poverty exhibit fewer affordances for child development. This study aimed to investigate the association between contextual factors and affordances in the home environments of infants facing poverty. Term infants (n = 128) were divided into two groups: (1) exposed group (EG), comprising term infants exposed to poverty, and (2) comparison group (CG), consisting of term infants classified with medium and high socio-economic status. The main dependent variables were physical space, variety of stimulation, gross and fine motor toys, and the total score; measured using the Brazilian version of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire, named Affordances no Ambiente Domiciliar para o Desenvolvimento Motor-Escala Bebê. Statistical analysis employed independent sample t-tests or Mann-Whitney tests, chi-square tests, and stepwise multiple linear regression models to evaluate predictors of less adequate home environments. The EG presented significantly fewer affordances in gross motor toys (Cohen's r = 0.353; p < 0.01); fine motor toys (Cohen's r = 0.327; p < 0.01); and total score (Cohen's r = 0.377; p < 0.01). Binary logistic regression analysis showed a significant association (r2 = 0.828, p < 0.01) between the less than adequate home environment category and maternal age (p = 0.043, OR: 0.829 (0.692-0.994)), revealing that maternal age was associated with better quantity and quality of affordances for child development.

Unveiling the Health Ramifications of Lead Poisoning: A Narrative Review

The presence of lead (Pb) in children's toys and paint is a significant global public health concern. Numerous studies conducted worldwide have measured lead concentrations in these products. This article aims to examine the research findings and shed light on the implications for human health, including legal consequences and public awareness. Despite regulations on lead levels in polyvinyl chloride (PVC) paints and children's toys in many countries, several reviewed documents indicate that these products often contain substantial amounts of lead, frequently surpassing legal limits. Particularly high levels of lead in paints have been found in countries such as China, Thailand, and Brazil. It is crucial to raise awareness among parents by educating them about this issue and empowering them to take proactive measures to protect their children from lead poisoning associated with toys and colored paints. There is also global support for eliminating lead pigments and regulating the amount of lead in PVC toys.

How Do Children Play with Toy Trains and for What Benefits? A Scoping Review

Children play with different toys in different ways which may be associated with different developmental outcomes. While existing work has investigated different categories of toys, differences may also be present within specific toy categories. Therefore, understanding how specific toys promote play behaviours and their associated developmental outcomes has important implications for teachers, parents, caregivers, and researchers. To better understand how children play with toy trains, whether groups of children show a particular preference for toy trains and what (if any) associated benefits there are for playing with toy trains, 36 studies published in psychology and educational databases up to December 2022 were reviewed. A key finding emerged regarding the importance of the structured, realistic, and familiar nature of toy trains being important for facilitating pretend play as well as social collaboration behaviours during social play. Whilst findings in relation to gender-stereotyped preferences for playing with toy trains were mixed and no gender differences were found in research investigating play styles, neurodivergent children were found to have a preference for toy trains. These findings are important given that certain play styles, pretend play in particular, have been associated with benefits in children's executive function, language, creativity, and social understanding.

Quantitative composite testing model based on measurement uncertainty and its application for the detection of phthalate esters

To improve the quantitative detection efficiency of chemical analysis and reduce the detection cost, the sample pass rate was estimated and mathematical statistics were used to calculate the optimal group size (K opt) of the composite testing to save on the maximum workload. A quantitative composite testing model was developed based on chemical analysis measurement uncertainty. Using this model, the maximum allowable number of composited samples (K max) is first calculated using parameters of regulated limits (L), limit of quantification (LOQ), and method measured uncertainty (U rel) to ensure that the sensitivity of the composite testing can meet the limit requirements. Finally, the appropriate composite group size (K a) can be obtained by creating a balance between K opt, K max, and the practical information used for that particular test. Furthermore, based on a constructed model, a practical quantitative composite testing method of 3-10 samples was established for the routine detection of toy phthalates (PAEs). The experimental results showed that the quantitative limits of 7 PAEs were 9.1-41.8 mg/kg, the relative expansion uncertainties were 16.6%-23.2%, and the recovery rates were 91.0%-112.3%, with a relative deviation of less than 10%. All these meet international PAEs standards. Compared with the traditional individual and qualitative composite testing, this model will not decrease the detection sensitivity, but can save up to 17.9%-80.4% of the workload when it is employed in toy PAEs testing with the pass rate of 80%-99%. This quantitative composite testing method will be implemented in the coming revision of ISO 8124-6 toy PAEs standards.

Preschool Children's Loose Parts Play and the Relationship to Cognitive Development: A Review of the Literature

Play is an integrative process, and the skills acquired in it-overcoming impulses, behavior control, exploration and discovery, problem-solving, reasoning, drawing conclusions, and attention to processes and outcomes are foundational cognitive structures that drive learning and motivation. Loose parts play is a prominent form of play that many scholars and educators explicitly endorse for cognitive development (e.g., divergent thinking, problem-solving). It is unique among play types because children can combine different play types and natural or manufactured materials in one occurrence. While educators and policymakers promote the benefits of loose parts play, no previous research has explored the direct relationship between preschool-age children's indoor loose parts play experiences and cognitive development. We address this gap by bringing together the relevant literature and synthesizing the empirical studies on common play types with loose parts, namely object and exploratory, symbolic and pretend, and constructive play. We also focus on studies that examine children's experiences through loose parts, highlighting the impact of different play types on learning through the reinforcement of cognitive skills, such as executive function, cognitive self-regulation, reasoning, and problem-solving. By examining the existing literature and synthesizing empirical evidence, we aim to deepen our understanding of the relationship between children's play with loose parts and its impact on cognitive development. Ultimately, pointing out the gaps in the literature that would add to the body of knowledge surrounding the benefits of play for cognitive development and inform educators, policymakers, and researchers about the significance of incorporating loose parts play into early childhood education.

An Italian survey on the microbiological safety of toys containing aqueous media

AIMS

The purpose of the present investigation is to fill the current gap in information regarding the microbiological quality of toys containing aqueous media and the related risks for users.

METHODS

Over eighteen years, a total of 491 sealed toys containing aqueous media were analysed using conventional microbial culture methods. In addition, molecular methods (PCR/nested RT-PCR, followed by Sanger sequencing) were employed to test for enteric viruses (enteroviruses and adenoviruses) in a subset of toys; subsequently, the infectivity of the positive samples was tested on cell cultures.

RESULTS

Of the examined toys, 23.8% were noncompliant with the limits of the European guideline. The most frequently exceeded limits were those for Aerobic bacteria (84.6%), and Pseudomonas aeruginosa (29.9%). Other opportunistic bacterial species that were frequently detected were Stenotrophomonas maltophilia, Pseudomonas fluorescens, Burkholderia cepacia Sphingomonas paucimobilis and Comamonas acidovorans. In a subset of 28 samples, adenovirus (25%) and enterovirus (11%) genome was also found to be present, although the samples with viral positivity did not show infectivity after inoculation on appropriate cell monolayers.

CONCLUSIONS

The results indicate a condition of microbial exposure related to the use of toys containing aqueous media.

SIGNIFICANCE AND IMPACT OF STUDY

The investigation highlights the need for more stringent monitoring during the production, packaging and storage of toys containing aqueous matrices in order to safeguard children's health.

Expanding the palette of pediatric playthings: A call to action for pediatric dermatologists

Children recognize race and skin color from a young age. Given the important role of play in the development of children's understanding of social norms and cultural values, it is essential to incorporate toys and other educational materials with diverse skin tones to teach children about race and skin color. Analyses of children's books and toys have shown a lack of diversity in representation of races and skin types. Pediatric dermatologists are uniquely positioned to foster conversations about skin tone and advocating for more diverse materials in classrooms and clinics. In this manuscript, we discuss best practices and resources for facilitating discussions on skin tone with children in the dermatology clinic.

Occupational physical risk factors and prevalence of musculoskeletal disorders among the traditional lacquerware toy makers of South India

BACKGROUND

The majority of handicraft workers in India falls under the informal sector, which plays a prominent role in the employment generation. Artisans in handicraft sectors encounter various hazards and risks causing occupational diseases.

OBJECTIVE

The key objective of the study is to identify the prevalence of musculoskeletal disorders and occupational risk factors among the artisans involved in making traditional lacquerware toys in Karnataka and Andhra Pradesh, South India.

METHODS

The subjects considered in this study are 177 artisans who work in mechanized lathes at Channapatna of Karnataka and Etikoppaka of Andhra Pradesh, South India. The information regarding the reported work-related musculoskeletal disorders (WMSD) symptoms from 7 days to 12 months are collected through modified Standardized Nordic Questionnaire and by direct observations. Moreover, the intervention of WMSD in their day-to-day life and the overall comfort of their body are also determined. The questionnaire survey is conducted through face-to-face interviews and by direct field study.

RESULTS

From the statistical analysis, it is found that about 76.83%of the study population (77.4%male and 74.28%female) has self-reported WMSDs. The prevalence of WMSD is most common in the age group of 30-40 years. Physical factors like workplace adaptability, stress at work, body postures, health status, body mass index, active and enough breaks during work and body condition at the end of work have a significant association with WMSD.

CONCLUSION

In this study, many of the work-related and lifestyle/health-related factors show a significant association with WMSD in artisans. The sub-standard working environment and the nature of work expose artisans to many occupational risks in their day-to-day life. To mitigate the occupational risks and musculoskeletal disorders, the workspace needs to be redesigned ergonomically.

When Parents Go Shopping: Perspectives on Gender-Typed Toys among Polish Mothers and Fathers from Big Cities

Children learn to understand gender categories and roles typical for women and men from the earliest stages of their life. Toys, by which they are surrounded in everyday routine, may have a significant role in their knowledge of cultural norms and societal expectations, but also might have a great impact on children’s health in the context of psychosocial development. Parental attitudes can also be an important moderator of the choice of gender-stereotyped toys. The aim of the study was to investigate parents’ perspectives on toys’ appropriateness for children according to gender, and to analyze parents’ knowledge about the labeling of toys in shops. In total, 526 parents from big cities participated in the study; to assess parental knowledge and perspectives on toys’ categorization, The World of Toys questionnaire was used. The results indicated that most parents from big cities observe that toys are arranged according to the child’s age and sex and the toys’ functionality. Moreover, in parents’ opinion, the compliance with the role of a woman or man affects categorization the most. Furthermore, both parents tended to attribute toys to both sexes more often than they believe the stores do. To conclude, despite the still visible division of toys in shops, Polish parents from big cities are more liberal and egalitarian than shops are when it comes to the perception of toys’ appropriateness, allowing children to play with most toys regardless of their sex.

Assessing Children's Fine Motor Skills With Sensor-Augmented Toys: Machine Learning Approach

Background

Approximately 5%-10% of elementary school children show delayed development of fine motor skills. To address these problems, detection is required. Current assessment tools are time-consuming, require a trained supervisor, and are not motivating for children. Sensor-augmented toys and machine learning have been presented as possible solutions to address this problem.

Objective

This study examines whether sensor-augmented toys can be used to assess children’s fine motor skills. The objectives were to (1) predict the outcome of the fine motor skill part of the Movement Assessment Battery for Children Second Edition (fine MABC-2) and (2) study the influence of the classification model, game, type of data, and level of difficulty of the game on the prediction.

Methods

Children in elementary school (n=95, age 7.8 [SD 0.7] years) performed the fine MABC-2 and played 2 games with a sensor-augmented toy called “Futuro Cube.” The game “roadrunner” focused on speed while the game “maze” focused on precision. Each game had several levels of difficulty. While playing, both sensor and game data were collected. Four supervised machine learning classifiers were trained with these data to predict the fine MABC-2 outcome: k-nearest neighbor (KNN), logistic regression (LR), decision tree (DT), and support vector machine (SVM). First, we compared the performances of the games and classifiers. Subsequently, we compared the levels of difficulty and types of data for the classifier and game that performed best on accuracy and F1 score. For all statistical tests, we used α=.05.

Results

The highest achieved mean accuracy (0.76) was achieved with the DT classifier that was trained on both sensor and game data obtained from playing the easiest and the hardest level of the roadrunner game. Significant differences in performance were found in the accuracy scores between data obtained from the roadrunner and maze games (DT, P=.03; KNN, P=.01; LR, P=.02; SVM, P=.04). No significant differences in performance were found in the accuracy scores between the best performing classifier and the other 3 classifiers for both the roadrunner game (DT vs KNN, P=.42; DT vs LR, P=.35; DT vs SVM, P=.08) and the maze game (DT vs KNN, P=.15; DT vs LR, P=.62; DT vs SVM, P=.26). The accuracy of only the best performing level of difficulty (combination of the easiest and hardest level) achieved with the DT classifier trained with sensor and game data obtained from the roadrunner game was significantly better than the combination of the easiest and middle level (P=.046).

Conclusions

The results of our study show that sensor-augmented toys can efficiently predict the fine MABC-2 scores for children in elementary school. Selecting the game type (focusing on speed or precision) and data type (sensor or game data) is more important for determining the performance than selecting the machine learning classifier or level of difficulty.

Cultural Significance of Beetles in Sub-Saharan Africa

An overview is given of how beetles are utilised, perceived, and experienced in daily life across sub-Saharan Africa. More than 300 people from 27 countries were interviewed and the results were compared with literature findings. Both the adults and larvae of many beetle species are eaten, mainly from the families Curculionidae, Buprestidae, Cerambycidae, Dytiscidae and Scarabaeidae. Some beetle species are used for medicinal purposes. The use of breast-shaped water beetles by adolescent girls to stimulate breast growth could be due to superstition or the effect of the defensive secretion containing steroid hormones. Blister beetles contain cantharidin, which influences the urinary tract, and is therefore used as an aphrodisiac and for treating venereal disease. Throughout Africa children play with beetles by letting them fly on a string. In the Sahel, the hard work of dung beetles is an inspiration for stories. Fireflies are generally associated with ghosts and witches, likely because the glowing of the beetles is interpreted as magical. Many beetle groups are brightly and attractively coloured and are therefore used in ceremonies and commerce. This type of indigenous knowledge, revealed in stories provided by older people, is rapidly disappearing due to urbanisation.

Magnet Ingestion in Children Management Guidelines and Prevention

Purpose: Foreign body ingestion is common in children, and most foreign bodies pass spontaneously without causing serious injuries. Ingestion of multiple high-power magnet pieces is unique and increases the risk of morbidity and mortality. The longer the duration of ingestion, the increased likelihood of complications. Various management options have been reported, and there is no consensus on the ideal management which necessitates the need for a practical algorithm. The incidence of magnet ingestion has been increasing and directly related to the laws and recalls. The aim of this review is to provide an easy and practical pathway for management and to highlight the preventive rules of the legislations and recalls. Methods: PubMed/MEDLINE, the Cochrane Database of Systematic Reviews, and the list of references from all identified complete publications were searched for all publications in English-language for pediatric magnet ingestion. Conclusion: Practical and time-saving management pathways are recommended to minimize the risk of complications. Preventive rules and recalls are important for eliminating the availability of these hazardous magnets. Public awareness about the unique risks posed by these magnets if ingested is important.

Toy Buying Today: Considerations, Information Seeking, and Thoughts about Manufacturer Suggested Age

Children frequently play with toys purchased by their parents, yet little is known about the how these toys are selected by parents. Mothers with children from 0-12 years of age filled out a survey about their toy purchasing habits. Results revealed that the most common place mothers sought out information about toys was online, and mothers most frequently found the manufacturers' suggested age only somewhat accurate. Further analyses demonstrated that mothers who bought their toys from different sources (i.e., online, stores, secondhand) considered dissimilar items before purchasing a toy for their child and obtained information in distinct ways. In contrast, regardless of where mothers purchased toys, they regarded the manufacturers' suggested age in the same way. This study is one of the few to examine parental toy selection patterns, providing useful knowledge for understanding how to reach parents and provide them information they desire when selecting toys for their children.

Particle and organic vapor emissions from children's 3-D pen and 3-D printer toys

Objective: Fused filament fabrication "3-dimensional (3-D)" printing has expanded beyond the workplace to 3-D printers and pens for use by children as toys to create objects.Materials and methods: Emissions from two brands of toy 3-D pens and one brand of toy 3-D printer were characterized in a 0.6 m3 chamber (particle number, size, elemental composition; concentrations of individual and total volatile organic compounds (TVOC)). The effects of print parameters on these emission metrics were evaluated using mixed-effects models. Emissions data were used to model particle lung deposition and TVOC exposure potential.Results: Geometric mean particle yields (106-1010 particles/g printed) and sizes (30-300 nm) and TVOC yields ( Collapse

Emissions of VOCs From Polymer-Based Consumer Products: From Emission Data of Real Samples to the Assessment of Inhalation Exposure

The development of consumerism led to an increase in toy production. Such consumer products may contain non-intentionally added toxic substances that can emit from the product and may be inhaled by the consumer. Little data is available on the inhalation exposure of humans to volatile organic compounds (VOCs) from consumer products, so a reliable exposure assessment is needed. Only the emission chamber technique developed for building material emissions can provide solid estimations as it allows the products to be studied under real room conditions. This paper proposes a strategy to interpret emission experiment results from consumer products and assess the corresponding potential risk. It focuses on 14 common VOCs. The identification of the polymer type of 41 plastic articles was first performed by pyrolysis coupled online to gas chromatography with mass spectrometric detection (pyr-GC/MS). Their VOC profile was also determined by Dynamic Headspace-GC/MS (DHS-GC/MS). Softer polymers caused higher and broader emission profiles. Four specific toy samples were selected to be studied in a 203 l emission chamber and their emissions were compared to a reference material. A rapid decrease in the emissions was observed for each product and VOC. Based on these emission curves over time, the corresponding indoor air concentration could be calculated for the target VOCs for short-term or long-term exposures. The indoor air levels obtained were at least 35 times lower than the levels according to conventional indoor air guidelines. Guideline values were only exceeded using very conservative exposure scenarios.

Bacterial Contamination of Children's Toys in Rural Day Care Centres and Households in South Africa

Background: Young children exhibit a high susceptibility to several diarrhoea-causing bacterial microorganisms. In this study, the prevalence of fecal contamination on children’s toys was determined using total coliform and E. coli as bacterial fecal indicators. The prevalence of diarrhoeagenic E. coli strains were used as an indication of the potential health risks. Materials and Methods: A cross-sectional descriptive study was carried out for 3 months in rural communities in the Vhembe district, Limpopo province of South Africa. Nonporous plastic toys (n = 137) used by children under 5 years of age in households and day care centres (DCCs) from rural villages were collected for assessment. New toys (n = 109) were provided to the households and DCCs and collected again after 4 weeks. Microbiological assessment was carried out using the Colilert^® Quanti-Tray/2000 system. Diarrhoeagenic E. coli strains were identified using a published multiplex PCR protocol. Results: Water, sanitation and hygiene (WASH) conditions of the children in the households and DCCs were assessed. Statistical analysis was used to identify the relationship between fecal contamination of the existing and introduced toys. All the existing and introduced toy samples, both from DCCs and households, tested positive for total coliform counts and 61 existing and introduced toy samples tested positive for E. coli counts. Diarrhoeagenic E. coli strains identified included EHEC, ETEC, EPEC, EIEC and EAEC. Conclusions: The results indicated that water, sanitation and hygiene conditions could be responsible in the contamination of children’s toys and the transmission of diarrhoea to young children.

Primary Teeth Bite Marks Analysis on Various Materials: A Possible Tool in Children Health Risk Analysis and Safety Assessment

BACKGROUND

All objects put into a child's mouth could be hazardous in terms of trauma and toxic substance exposure. The aims of this study were to evaluate morphological characteristics of the primary teeth bite marks inflicted on various materials and to assess material wear using experimental model.

METHODS

Bite marks were analyzed on five materials: rubber, plastic, foil, wood, and silicone. In order to mimic children mouthing behavior an experimental setup has been designed using primary teeth placed in dentures and children's equipment specimens.

RESULTS

Deciduous teeth make visible and recognizable traces when using physiological forces on all investigated materials. The most significant material loss was revealed in silicone samples, but it has been observed in all material groups, while mouthing with incisors using higher mastication forces were identified as significant predictors for material wear. There were no significant differences between type, species, and morphological-morphometric characteristics of the bite marks which are made by incisors, canines, and molars.

CONCLUSIONS

In the range of physiological bite forces, deciduous teeth lead to wear of material from which toys are made while the analysis of bite marks in children equipment could give some information regarding the risk of trauma and exposure.

[Determination of monomethyltin migration from toys by gas chromatography-mass spectrometry and confirmation of its false positive]

Based on migration procedures using simulated gastric juice specified in the EU toy Safety Standard EN 71-3:2013/A2:2017, a method was developed for the determination of monomethyltin (MMT) migration from toys by gas chromatography-mass spectrometry (GC-MS). Further, a reliable confirmation method for judgement of a false positive for MMT obtained by GC-MS, was established. After optimizing the migration conditions, derivatization steps and chromatographic parameters, the method yielded a linear range from 0.02 to 1.0 mg/L with a correlation coefficient (R²) of 0.9992. The limits of detection and quantification of the method were 0.11 and 0.32 mg/kg, respectively. The recoveries were 86.2%-104.2% under different spiked levels (0.5, 1.0 and 1.5 μg), and the relative standard deviations were 3.1%-8.2% (n=6). MMT migration ranging from 0.44 to 0.67 mg/kg was detected in the surface coating of tin-plating (Sn-Fe alloy) toy materials, which was subsequently confirmed to be false positive. Therefore, a novel confirmative approach using methanol or acetone as the migration solvent was proposed, aiming at verifying the false positive of MMT. The results showed that the previously positive MMT detected by GC-MS could no longer be detected when treated by these migration solvents.Hence, this approach can be used to confirm false positive detected for MMT after GC-MS detection.

Analysis and Assessment of Exposure to Selected Phthalates Found in Children's Toys in Christchurch, New Zealand

Internationally several phthalates are subject to regulatory control regarding maximum allowable concentrations in children's toys. Such regulation is not in place in New Zealand. Phthalates have been associated with developmental toxicity and endocrine disruption. We determined the concentration of seven phthalates in children's toys purchased in Christchurch, New Zealand. These results provided data for an exposure assessment deriving Hazard Indices (HI) for oral and dermal exposure routes in children, based on the concentration of mixtures of phthalates shown by the EU to produce either reproductive/developmental or hepatotoxic effects. Of the 49 toys analyzed, 65% contained at least one phthalate at a concentration of >0.1% by mass; and 35% contained multiple-phthalates at individual concentrations of >0.1%. A HI of 3.4 was derived for the combined exposures to the four phthalates associated with reproductive and developmental effects. A HI of 0.3 was derived for the group of phthalates associated with hepatotoxic effects. Five phthalates were detected at levels exceeding the EU regulatory limit of 0.1% by mass. Risk assessment calculations indicate that, using realistic exposure scenarios, the worst-case combined exposure to phthalates associated with developmental toxicity exceeded a HI of 1 so may cause adverse developmental effects.

TOY SAFETY SURVEILLANCE FROM ONLINE REVIEWS

Toy-related injuries account for a significant number of childhood injuries and the prevention of these injuries remains a goal for regulatory agencies and manufacturers. Text-mining is an increasingly prevalent method for uncovering the significance of words using big data. This research sets out to determine the effectiveness of text-mining in uncovering potentially dangerous children's toys. We develop a danger word list, also known as a 'smoke word' list, from injury and recall text narratives. We then use the smoke word lists to score over one million Amazon reviews, with the top scores denoting potential safety concerns. We compare the smoke word list to conventional sentiment analysis techniques, in terms of both word overlap and effectiveness. We find that smoke word lists are highly distinct from conventional sentiment dictionaries and provide a statistically significant method for identifying safety concerns in children's toy reviews. Our findings indicate that text-mining is, in fact, an effective method for the surveillance of safety concerns in children's toys and could be a gateway to effective prevention of toy-product-related injuries.

Lead migration from toys by anodic stripping voltammetry using a bismuth film electrode

Metals may be released from toys via saliva during mouthing, via sweat during dermal contact, or via gastric and intestinal fluids after partial or whole ingestion. In this study, we determined the lead migration from toys bought on the Portuguese market for children below 3 years of age. The lead migration was performed according to the European Committee for Standardization EN 71-3, which proposes a 2-hour migration test that simulates human gastric conditions. The voltammetric determination of migrated lead was performed by anodic stripping voltammetry (ASV) at a bismuth film electrode (BiFE). For all the analyzed toys, the values of migrated lead did not exceed the limits imposed by the European Committee for Standardization EN 71-3 (90 mg kg^-1) and by the EU Directive 2009/48/EC (13.5 mg kg^-1) on the safety of toys.

Metal Contamination in Low-Cost Jewelry and Toys in Cambodia

BACKGROUND

The existence of lead-contaminated consumer products is a global issue. Toys and low-cost jewelry may contain toxic metals and Cambodia is known to have consumer products with toxic metals.

OBJECTIVES

It is important to inform Cambodians about sources of toxic metals so that they can reduce their exposure risk, particularly for children.

METHODS

Student volunteers purchased, or brought from home, low-cost jewelry and toys to either the University of Health Science or a Don Bosco Institute in Phnom Penh, Cambodia, where they were analyzed using X-ray fluorescence (XRF). The initial analysis was performed in 2011. A subset of the 2011 samples was re-analyzed in 2015 using new preparation techniques and a new x-ray fluorescence (XRF) unit.

DISCUSSION

The analysis of low-cost jewelry in Phnom Penh in 2015 indicated that lead in jewelry clasps is a more serious health concern than was first perceived in 2011. Mercury, nickel, cadmium and copper were also found in toys, and occasionally these toys had been produced by well-known companies. Sources of jewelry production of samples in the present study are unknown. Lead in clasps in low-cost jewelry appeared to be the greatest risk to children in our sampling.

CONCLUSION

One-third of toys and low-cost jewelry exceeded the United States and European Union guidelines for heavy metals. XRF analysis allows for rapid screening of lead and other toxic metals and could be used to reduce the sales of low-cost jewelry and toys containing toxic metals.

Estimating children's exposure to toxic elements in contaminated toys and children's jewelry via saliva mobilization

Children's potential for exposure to potentially toxic elements in contaminated jewelry and toys via mouth contact has not yet been fully evaluated. Various toys and jewelry (metallic toys and jewelry [MJ], plastic toys, toys with paint or coating, and brittle/pliable toys; n = 32) were tested using the saliva extraction (mouthing) compartment of the DIN and RIVM bioaccessibility protocols to assess As, Ba, Cd, Cr, Cu, Mn, Ni, Pb, Sb, and Se mobilization via saliva. Total concentrations of As, Cd, Cu, Ni, Pb, and Sb were found elevated in analyzed samples. Four metals were mobilized to saliva from 16 MJ in significant quantities (>1 μg for highly toxic Cd and Pb, >10 μg for Cu and Ni). Bioaccessible concentrations and hazard index values for Cd exceeded limit values, for young children between 6 mo- and 3 yr-old and according to both protocols. Total and bioaccessible metal concentrations were different and not always correlated, encouraging the use of bioaccessibility for more accurate hazard assessments. Bioaccessibility increased with increasing extraction time. Overall, the risk from exposure to toxic elements via mouthing was high only for Cd and for MJ. Further research on children's exposure to toxic elements following ingestion of toy or jewelry material is recommended.

Toys and toilets: cross-sectional study using children's toys to evaluate environmental faecal contamination in rural Bangladeshi households with different sanitation facilities and practices

OBJECTIVE

To evaluate household faecal contamination using children's toys among 100 rural Bangladeshi households categorised as 'cleaner' (toilet that reliably separates faeces from the environment and no human faeces in/around living space) or 'less clean' (no toilet or toilet that does not reliably separate faeces from the environment and human faeces in/around living space).

METHODS

We distributed toy balls to each household and rinsed each study toy and a toy already owned by the household in 200 ml of Ringer's solution. We enumerated faecal coliforms and faecal streptococci from each rinse using membrane filtration methods.

RESULTS

Study toys from 39 cleaner households had lower mean faecal coliform contamination than toys from 61 less clean households (2.4 log10 colony-forming units (CFU)/200 ml vs. 3.2 log10 CFU/200 ml, P = 0.03). However, wealth measures explained a portion of this relationship. Repeat measures were moderately variable [coefficient of variation (CV) = 6.5 between two toys in the household at the same time, CV = 37.6 between toys in the household at two different times 3-4 days apart]. Too few households owned a non-porous toy to compare groups without risk of bias.

CONCLUSION

In rural Bangladesh, improved sanitation facilities and practices were associated with less environmental contamination. Whether this association is independent of household wealth and whether the difference in contamination improves child health merit further study. The variation found was typical for measures of environmental contamination, and requires large sample sizes to ascertain differences between groups with statistical significance.

Detection of pathogenic micro-organisms on children's hands and toys during play

AIMS

This study aimed to determine if the children's leisure activities impact the presence of pathogens on their hands and toys.

METHODS & RESULTS

To assess the microbiological hazard in playground areas, a pilot study that included 12 children was conducted. We then conducted an intervention study; children's hands and toys were washed before playing. Faecal coliforms, pathogenic bacteria and Giardia lamblia were quantified by membrane filtration, selective media and flotation techniques, respectively; rotavirus, hepatitis A and rhinovirus by RT-PCR. Pilot study results revealed faecal contamination on children's hands and toys after playing on sidewalks and in public parks. Pathogenic bacteria, hepatitis A and G. lamblia on children's hands were also found. In the intervention study, Staphylococcus aureus and Klebsiella pneumoniae were found on children's hands at concentrations up to 2·5 × 10(4) and 1 × 10(4) CFU hands(-1), respectively. E. coli and Kl. pneumoniae were detected on toys (2·4 × 10(3) and 2·7 × 10(4) CFU toy(-1), respectively). Salmonella spp, Serratia spp and G. lamblia cysts were also present on toys.

CONCLUSION

Children's play activities influence microbial presence on hands and toys; the transfer seems to occur in both ways.

SIGNIFICANCE AND IMPACT OF THE STUDY

Control strategy needs to be implemented to protect children from infectious diseases.

Modified ride-on toy cars for early power mobility: a technical report

BACKGROUND AND PURPOSE

Children with significantly decreased mobility have limited opportunities to explore their physical and social environment. A variety of assistive technologies are available to increase mobility; however, no single device provides the level of functional mobility that children developing typically enjoy. The purpose of this technical report is to formally introduce a new power mobility option--the modified ride-on toy car.

KEY POINTS

This report will provide (a) an overview of toy car features, (b) examples of basic electrical and mechanical modifications, and (c) a brief clinical case.

CLINICAL IMPLICATIONS

With creative use and customized modifications, toy cars can function as a "general learning environment" for use in the clinic, home, and school. As such, we anticipate that these cars will become a multiuse clinical tool to address not only mobility goals but also goals involving body function and structure such as posture and movement impairments.

Play therapy: considerations and applications for the practitioner

Play therapy represents a unique form of treatment that is not only geared toward young children, but is translated into a language children can comprehend and utilize-the language of play. For the referring provider or practitioner, questions may remain regarding the nature, course, and efficacy of play therapy. This article reviews the theoretical underpinnings of play therapy, some practical considerations, and finally a summary of the current state of research in regard to play therapy. The authors present the practicing psychiatrist with a road map for referring a patient to play therapy or initiating it in appropriate cases.
