To evaluate the normal development of the paranasal sinuses in children with CT, authors prospectively studied with brain CT scans of 260 children without known sinus disease, ranging image from 7 days to 16 years. Maximal anteroposterior and transverse diameters(mm) and maximal cross- sectional area(mm 2 ) of both sides of the maxillary sinus were measured with the aid of computer device. As to the ethmoidal and spheroidal sinuses, we simply documented the presence of the aplastic ethmoidal sinus and calculated the age-incidence of the spheroidal sinus pneumatization, respectively.There noted three phases in the development of the maxillary sinus. The anteroposterior and transverse diameters of the maxillary sinus increased nearly in parallel. The former was always greater than the latter. In no cases was the edathamil sinus aplastic and almost all sinuses were pneumatized even in infants as early as 7 old days. CT identified the conchal pattern of sphenoidal sinus pneumatization infants as early as 11 days old. Sphenoidal sinus pneumatization was seen in 38% of the children under the age of 1 year, 82% of the children between the age of 1 and 2 years, and almost all children older than 2 years. The anteroposterior and transverse diameters of the maxillary sinus seem to reach the adult size by 8 years of age, and the conchal pattern of sphemoidal sinus pneumatization can be recognized earlier with CT than on the plain radiographs

In sub-Saharan Africa, malaria is frequently overdiagnosed as the cause of an undifferentiated febrile illness, whereas arboviral illnesses are presumed to be underdiagnosed. Sera from 385 febrile Kenyan children, who presented to 1 of 4 clinical sites, were tested using microscopy and real-time molecular assays for dengue virus (DENV), chikungunya virus (CHIKV), malaria, and Leptospira . Malaria was the primary clinical diagnosis for 254 patients, and an arboviral infection (DENV or CHIKV) was the primary diagnosis for 93 patients. In total, 158 patients (41.0%) had malaria and 32 patients (8.3%) had CHIKV infections. Compared with real-time polymerase chain reaction, microscopy demonstrated a percent positive agreement of 49.7%. The percentage of malaria cases detected by microscopy varied significantly between clinical sites. Arboviral infections were the clinical diagnosis for patients on the Indian Ocean coast (91 of 238, 38.2%) significantly more often than patients in the Lake Victoria region (2 of 145, 1.4%; P < .001). However, detection of CHIKV infections was significantly higher in the Lake Victoria region (19 of 145 [13.1%] vs 13 of 239 [5.4%]; P = .012). The clinical diagnosis of patients with an acute febrile illness, even when aided by microscopy, remains inaccurate in malaria-endemic areas, contributing to inappropriate management decisions.

To compare interocular acuity differences, crowding ratios, and binocular summation ratios in 4- to 8-year-old children with albinism (n = 16), children with infantile nystagmus syndrome (n = 10), and children with normal vision (n = 72). Interocular acuity differences and binocular summation ratios were compared between groups. Crowding ratios were calculated by dividing the single Landolt C decimal acuity with the crowded Landolt C decimal acuity mono- and binocularly. A linear regression analysis was conducted to investigate the contribution of 5 predictors to the monocular and binocular crowding ratio: nystagmus amplitude, nystagmus frequency, strabismus, astigmatism, and anisometropia. Crowding ratios were higher under mono- and binocular viewing conditions for children with infantile nystagmus syndrome than for children with normal vision. Children with albinism showed higher crowding ratios in their poorer eye and under binocular viewing conditions than children with normal vision. Children with albinism and children with infantile nystagmus syndrome showed larger interocular acuity differences than children with normal vision (0.1 logMAR in our clinical groups and 0.0 logMAR in children with normal vision). Binocular summation ratios did not differ between groups. Strabismus and nystagmus amplitude predicted the crowding ratio in the poorer eye (p = 0.015 and p = 0.005, respectively). The crowding ratio in the better eye showed a marginally significant relation with nystagmus frequency and depth of anisometropia (p = 0.082 and p = 0.070, respectively). The binocular crowding ratio was not predicted by any of the variables. Children with albinism and children with infantile nystagmus syndrome show larger interocular acuity differences than children with normal vision. Strabismus and nystagmus amplitude are significant predictors of the crowding ratio in the poorer eye.

Full Text Available Abstract Background Children with severe malnutrition who develop shock have a high mortality. Contrary to contemporaneous paediatric practice, current guidelines recommend use of low dose hypotonic fluid resuscitation (half-strength Darrows/5% dextrose (HSD/5D. We evaluated the safety and efficacy of this guideline compared to resuscitation with a standard isotonic solution. Methods A Phase II randomised controlled, safety and efficacy trial in Kenyan children aged over 6 months with severe malnutrition and shock including children with severe dehydration/shock and presumptive septic shock (non-diarrhoeal shock. Eligible children were randomised to HSD/5D or Ringer's Lactate (RL. A maximum of two boluses of 15 ml/kg of HSD/5D were given over two hours (as recommended by guidelines while those randomised to RL received 10 ml/kg aliquots half hourly (maximum 40 ml/kg. Primary endpoint was resolution of shock at 8 and 24 hours. Secondary outcomes included resolution of acidosis, adverse events and mortality. Results 61 children were enrolled: 41 had shock and severe dehydrating diarrhoea, 20 had presumptive septic shock; 69% had decompensated shock. By 8 hours response to volume resuscitation was poor with shock persisting in most children:-HSD/5D 15/22 (68% and RL14/25 (52%, p = 0.39. Oliguria was more prevalent at 8 hours in the HSD/5D group, 9/22 (41%, compared to RL-3/25 (12%, p = 0.02. Mortality was high, HSD/5D-15/26(58% and RL 13/29(45%; p = 0.42. Most deaths occurred within 48 hours of admission. Neither pulmonary oedema nor cardiogenic failure was detected. Conclusions Outcome was universally poor characterised by persistence of shock, oliguria and high case fatality. Isotonic fluid was associated with modest improvement in shock and survival when compared to HSD/5D but inconclusive due to the limitations of design and effectiveness of either resuscitation strategy. Although isotonic fluid resuscitation did not result in cardiogenic heart

A cochlear implant is a device that helps hearing-impaired children by transmitting sound signals to the brain and helping them improve their speech, language, and social interaction. Although various studies have investigated the different aspects of speech perception and language acquisition in cochlear-implanted children, little is known about their social skills, particularly Persian-speaking cochlear-implanted children. Considering the growing number of cochlear implants being performed in Iran and the increasing importance of developing near-normal social skills as one of the ultimate goals of cochlear implantation, this study was performed to compare the social interaction between Iranian cochlear-implanted children who have undergone rehabilitation (auditory verbal therapy) after surgery and normal-hearing children. This descriptive-analytical study compared the social interaction level of 30 children with normal hearing and 30 with cochlear implants who were conveniently selected. The Raven test was administered to the both groups to ensure normal intelligence quotient. The social interaction status of both groups was evaluated using the Vineland Adaptive Behavior Scale, and statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 21. After controlling age as a covariate variable, no significant difference was observed between the social interaction scores of both the groups (p > 0.05). In addition, social interaction had no correlation with sex in either group. Cochlear implantation followed by auditory verbal rehabilitation helps children with sensorineural hearing loss to have normal social interactions, regardless of their sex.

The cost of uncomplicated childhood fevers to Kenyan households: implications for reaching international access targets

Full Text Available Abstract Background Fever is the clinical hallmark of malaria disease. The Roll Back Malaria (RBM movement promotes prompt, effective treatment of childhood fevers as a key component to achieving its optimistic mortality reduction goals by 2010. A neglected concern is how communities will access these new medicines promptly and the costs to poor households when they are located in rural areas distant to health services. Methods We assemble data developed between 2001 and 2002 in Kenya to describe treatment choices made by rural households to treat a child's fever and the related costs to households. Using a cost-of-illness approach, we estimate the expected cost of a childhood fever to Kenyan households in 2002. We develop two scenarios to explore how expected costs to households would change if more children were treated at a health care facility with an effective antimalarial within 48 hours of fever onset. Results 30% of uncomplicated fevers were managed at home with modern medicines, 38% were taken to a health care facility (HCF, and 32% were managed at home without the use of modern medicines. Direct household cash expenditures were estimated at $0.44 per fever, while the total expected cost to households (cash and time of an uncomplicated childhood fever is estimated to be $1.91. An estimated mean of 1.42 days of caretaker time devoted to each fever accounts for the majority of household costs of managing fevers. The aggregate cost to Kenyan households of managing uncomplicated childhood fevers was at least $96 million in 2002, equivalent to 1.00% of the Kenyan GDP. Fewer than 8% of all fevers were treated with an antimalarial drug within 24 hours of fever onset, while 17.5% were treated within 48 hours at a HCF. To achieve an increase from 17.5% to 33% of fevers treated with an antimalarial drug within 48 hours at a HCF (Scenario 1, children already being taken to a HCF would need to be taken earlier. Under this scenario, direct cash

Wiefferink, Carin H; Rieffe, Carolien; Ketelaar, Lizet; Frijns, Johan H M

2012-06-01

The purpose of the present study was to compare children with a cochlear implant and normal hearing children on aspects of emotion regulation (emotion expression and coping strategies) and social functioning (social competence and externalizing behaviors) and the relation between emotion regulation and social functioning. Participants were 69 children with cochlear implants (CI children) and 67 normal hearing children (NH children) aged 1.5-5 years. Parents answered questionnaires about their children's language skills, social functioning, and emotion regulation. Children also completed simple tasks to measure their emotion regulation abilities. Cochlear implant children had fewer adequate emotion regulation strategies and were less socially competent than normal hearing children. The parents of cochlear implant children did not report fewer externalizing behaviors than those of normal hearing children. While social competence in normal hearing children was strongly related to emotion regulation, cochlear implant children regulated their emotions in ways that were unrelated with social competence. On the other hand, emotion regulation explained externalizing behaviors better in cochlear implant children than in normal hearing children. While better language skills were related to higher social competence in both groups, they were related to fewer externalizing behaviors only in cochlear implant children. Our results indicate that cochlear implant children have less adequate emotion-regulation strategies and less social competence than normal hearing children. Since they received their implants relatively recently, they might eventually catch up with their hearing peers. Longitudinal studies should further explore the development of emotion regulation and social functioning in cochlear implant children. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The Assessment of Systemic Risk in the Kenyan Banking Sector

Full Text Available The present paper aims to assess the systemic risk of the Kenyan banking system. We propose a theoretical framework to reveal the time evolution of the systemic risk using sequences of financial data and use the framework to assess the systemic risk of the Kenyan banking system that is regarded as the largest in the East and Central African region. Firstly, we estimate the bilateral exposures matrix using aggregate financial data on loans and deposits from annual reports and analyze the interconnectedness in the market using network centrality measures. Next, we extend the Eisenberg–Noe method to a multiperiod setting to the systemic risk of the Kenyan banking system, in which the multiperiod includes the dynamic evolutions of the Kenyan banking system of every bank and the structure of the interbank network system. We apply this framework to assess dynamically the systemic risk of the Kenyan banking system between 2009 and 2015. The main findings are the following. The theoretical network analysis using network centrality measures showed several banks displaying characteristics of systematically important banks (SIBs. The theoretical default analysis showed that a bank suffering a basic default will trigger a contagious default that caused several other banks in the sector to go bankrupt. Further stress test proved that the KCB bank theoretically caused a few contagious defaults due to an unusually high interconnectedness. This methodology can contribute by being part of monitoring system of the Central Bank of Kenya (regulatory body as well as the implementation of policies (such as bank-internal stress tests that assist in preventing default contagion.

Structural and functional perspectives on classification and seriation in psychotic and normal children.

Breslow, L; Cowan, P A

1984-02-01

This study describes a strategy for examining cognitive functioning in psychotic and normal children without the usual confounding effects of marked differences in cognitive structure that occur when children of the same age are compared. Participants were 14 psychotic children, 12 males and 2 females, mean age 9-2, matched with normal children at preoperational and concrete operational stage levels on a set of Piagetian classification tasks. The mean age of the normal children was 6-4, replicating the usually found developmental delay in psychotic samples. Participants were then compared on both structural level and functional abilities on a set of tasks involving seriation of sticks; the higher-level children were also administered a seriation drawing task. Analysis of children's processes of seriating and seriation drawings indicated that over and above the structural retardation, psychotic children at all levels showed functional deficits, especially in the use of anticipatory imagery. The implications for general developmental theory are that progress in structural development is not sufficient for imaginal development, and that structural development of logical concepts is relatively independent of the development of imagery. It was suggested that "thought disorder" may not be a disordered structure of thinking or a retardation in psychotic populations but rather a mismatch between higher-level logical structures and lower-level functions.

Correlates of disclosure of sexual violence among Kenyan youth.

Sexual violence (SV) against children is a global health and human rights issue that can have short and long-term consequences for health and wellbeing. Disclosing SV increases the likelihood that children can access health and protective services and receive psychosocial support. Research in high-income countries has found that child SV survivors are more likely to disclose when they are girls/women, experience fewer SV events, and experience SV perpetrated by a stranger. No studies have examined correlates of SV disclosure in Kenya. The objective of this research was to assess the correlates of disclosing SV among Kenyan youth ages 13-24 who reported an SV experience before age 18. In 2010, the Kenya Ministry of Gender, Children and Social Development, the U.S. Centers for Disease Control and Prevention's (CDC) Division of Violence Prevention, the UNICEF Kenya Country Office, and the Kenya National Bureau of Statistics (KNBS) conducted a national survey of violence against children. These data were used to conduct weighted logistic regression analyses to determine which factors were correlated with reporting SV disclosure. Among the 27.8% of girls/women and 14.5% of boys/men who reported SV before age 18, 44.6% of girls/women and 28.2% of boys/men reported to have disclosed the experience. In weighted logistic regression analysis, the odds of disclosure were lower among survivors who were boys/men and among survivors who reported more SV events, and higher when any perpetrator was a family member. More context-specific research on SV disclosure among young people is needed globally. Copyright © 2018 Elsevier Ltd. All rights reserved.

Associations between the size of the amygdala in infancy and language abilities during the preschool years in normally developing children.

Recently, structural MRI studies in children have been used to examine relations between brain volume and behavioral measures. However, most of these studies have been done in children older than 2 years of age. Obtaining volumetric measures in infants is considerably more difficult, as structures are less well defined and largely unmyelinated, making segmentation challenging. Moreover, it is still unclear whether individual anatomic variation across development, in healthy, normally developing infants, is reflected in the configuration and function of the mature brain and, as importantly, whether variation in infant brain structure might be related to later cognitive and linguistic abilities. In this longitudinal study, using T1 structural MRI, we identified links between amygdala volume in normally developing, naturally sleeping, 6-month infants and their subsequent language abilities at 2, 3 and 4 years. The images were processed and manually segmented using Cardviews to extract volumetric measures. Intra-rater reliability for repeated segmentation was 87.73% of common voxel agreement. Standardized language assessments were administered at 6 and 12 months and at 2, 3 and 4 years. Significant and consistent correlations were found between amygdala size and language abilities. Children with larger right amygdalae at 6 months had lower scores on expressive and receptive language measures at 2, 3, and 4 years. Associations between amygdala size and language outcomes have been reported in children with autism. The findings presented here extend this association to normally developing children, supporting the idea that the amygdalae might play an important but as yet unspecified role in mediating language acquisition.

Sensory properties of some foods may be of importance to energy consumption and thus the development and maintenance of childhood obesity. This study compares selected food related qualities in overweight and normal weight children. Ninety-two participants were included; 55 were overweight with a mean age of 11.6 years (range 6-18 years) and a mean BMI z-score of 2.71 (range 1.29-4.60). The 37 normal weight children had a mean age of 13.0 years (range 6-19 years) and a mean BMI z-score of 0.16 (range -1.71 to 1.24). All children completed a half-hour long meal test consisting of alternation between consumption of foods and answering of questionnaires. Compared to the normal weight, the overweight children displayed lower self-reported intake paces (χ 2 (2) = 6.3, p = 0.04), higher changes in liking for mozzarella (F(1,63) = 9.55, p = 0.003) and pretzels (F(1,87) = 5.27, p = 0.024), and declines in wanting for something fat, of which the normal weight children displayed an increase (F(1,83) = 4,10, p = 0.046). No differences were found for sensory-specific satiety, wanting for the main food yoghurt, hunger, or satiety. In conclusion, overweight children did not differ from normal weight children in terms of sensory-specific satiety, hunger, or satiety. However, overweight children had lower intake paces and appeared to differ from normal weight children regarding foods with a fatty taste. Copyright © 2016 Elsevier Ltd. All rights reserved.

In the midst of the current environmental crisis, scientists, academics, authors, and politicians worldwide are urging citizens to create sustainable communities. However, there is little capability to build a sustainable society without an informed, active, and engaged populous. This requires more than just environmentally knowledgeable citizens. It requires a society that understands the principles of the environment and can also exemplify them in daily life. In order to create a more environmentally literate world, there has been a push for environmental education integrated into schools. This qualitative study sought to examine Kenyan teachers' perspectives on the human-nature interaction by conducting vignette focus-group interviews. It is a subject not widely explored but vital for conservation not only in this area, but also other areas that seek to have an ecological informed populous. The vignettes were created using photographs and explanations of the photographs that the participants collected and emailed to the authors. For the focus-group vignette interviews, there were a total of 55 participants (30 females and 25 males). After InVivo analysis, we had 6 codes (resentment, pride, perils, blame, pragmatism, and self-interested) within 3 major themes. This study has implications for informing science education to combat these traditions of subjecting students to a science curriculum that demotes Kenyan cultural heritage and lifestyle. By incorporating local knowledge such as the ideas discussed in this paper into Kenyan science education, Kenyans can reach one of most challenging objectives of education, which is to produce children who are fundamentally aware of their environment.

Lung auscultation has long been a standard of care for the diagnosis of respiratory diseases. Recent advances in electronic auscultation and signal processing have yet to find clinical acceptance; however, computerized lung sound analysis may be ideal for pediatric populations in settings, where skilled healthcare providers are commonly unavailable. We described features of normal lung sounds in young children using a novel signal processing approach to lay a foundation for identifying pathologic respiratory sounds. 186 healthy children with normal pulmonary exams and without respiratory complaints were enrolled at a tertiary care hospital in Lima, Peru. Lung sounds were recorded at eight thoracic sites using a digital stethoscope. 151 (81%) of the recordings were eligible for further analysis. Heavy-crying segments were automatically rejected and features extracted from spectral and temporal signal representations contributed to profiling of lung sounds. Mean age, height, and weight among study participants were 2.2 years (SD 1.4), 84.7 cm (SD 13.2), and 12.0 kg (SD 3.6), respectively; and, 47% were boys. We identified ten distinct spectral and spectro-temporal signal parameters and most demonstrated linear relationships with age, height, and weight, while no differences with genders were noted. Older children had a faster decaying spectrum than younger ones. Features like spectral peak width, lower-frequency Mel-frequency cepstral coefficients, and spectro-temporal modulations also showed variations with recording site. Lung sound extracted features varied significantly with child characteristics and lung site. A comparison with adult studies revealed differences in the extracted features for children. While sound-reduction techniques will improve analysis, we offer a novel, reproducible tool for sound analysis in real-world environments.

Socio-cultural determinants of health-seeking behaviour on the Kenyan coast: a qualitative study.

Full Text Available Severe childhood illnesses present a major public health challenge for Africa, which is aggravated by a suboptimal response to the child's health problems with reference to the health-seeking behaviour of the parents or guardians. We examined the health-seeking behaviour of parents at the Kenyan coast because understanding impediments to optimal health-seeking behaviour could greatly contribute to reducing the impact of severe illness on children's growth and development.Health-seeking behaviour, and the factors influencing this behaviour, were examined in two traditional communities. We held in-depth interviews with 53 mothers, fathers and caregivers from two rural clinics at the Kenyan Coast. Biomedical medicine (from health facilities and purchased over the counter was found to be the most popular first point of treatment. However, traditional healing still plays a salient role in the health care within these two communities. Traditional healers were consulted for various reasons: a attribution of causation of ill-health to supernatural sources, b chronic illness (inability of modern medicine to cure the problem and c as prevention against possible ill-health. In developing an explanatory model of decision-making, we observed that this was a complex process involving consultation at various levels, with elders, but also between both parents, depending on the perceived nature and chronicity of the illness. However, it was reported that fathers were the ultimate decision makers in relation to decisions concerning where the child would be taken for treatment.Health systems need to see traditional healing as a complementary system in order to ensure adequate access to health care. Importantly, fathers also need to be addressed in intervention and education programs.

Working memory (WM) is very important for normal development. The fronto-parietal neuronal network supporting WM has already been well-studied. Less is known about the cortical activity changes during development of WM. We evaluated the maturation of visual WM network at the electrophysiological level in a group of normally developing children. Multichannel (n=31) event-related potentials (ERP) were measured during a visuo-spatial backmatching task in 69 childrens (6-16 years old). One-backmatching (BM1) and two-backmatching (BM2) tasks were performed. Age-related changes in behavioral parameters (commission and omission errors and reaction times) and ERP parameters (peak amplitudes and latencies) were analyzed between different ages. Clear improvement in performance from young childhood toward adolescence was seen at the behavioral level: decrease of errors and fastening of reaction times. At the electrophysiological level age-related changes were seen in peak latencies and especially in amplitudes. Different peaks have different dynamics in amplitudes and latencies: early peak amplitude decreased and latency shortened with age, which was not always seen in late peaks. This reflects developmental changes in intensity and speed of WM processing. Later peaks were more clearly seen over the right hemisphere in older children, illustrating hemispheric lateralization in visuo-spatial working memory. Our results indicate that not only at the behavioral but also at the electrophysiological level clear age-related dynamics in WM processing can be seen. Furthermore, with ERP we showed that different WM components follow different developmental trajectories. Our work demonstrates that age-related dynamics in intensity and speed of information processing during WM task is reflected in developmental changes in different ERP components. It also states that fronto-parietal visual WM network can be functional even before all its nodes are fully mature. Copyright © 2012 The

Magnetic resonance (MR) imaging may provide a radiation-sparing alternative to CT in diagnosing appendicitis in children in whom US is equivocal. However, comparability with CT in the detection of the appendix remains to be established. To determine the detection rate of the normal appendix in children on oral and IV contrast-enhanced MRI. MR imaging of 58 patients who had previously undergone MR enterography was retrospectively reviewed. Detection rate, body mass index, age and gender were recorded. The normal appendix was detected in 28 cases (48 %), with greatest detection rate on the axial fast imaging employing steady-state acquisition (FIESTA) sequence. Children in whom the appendix was detected had significantly higher BMI compared to children in whom the appendix was not seen. Neither age nor gender demonstrated a significant association with detection rate. The detection rate of the normal appendix in children on oral and IV contrast-enhanced MRI was 48 %, which is comparable to detection rates on CT, as well as to previously reported detection rates on MR imaging with neither oral nor IV contrast agents. These findings may serve to guide the development of MRI protocols for pediatric appendicitis. (orig.)

Full Text Available Objectives: A large number of congenitally deaf children are born annually. If not treated, this will have destructive effects on their language and speech development, educational achievements and future occupation. In this study it has been tried to determine the level of language skills in children with Cochlear Implants (CI in comparison with Normal Hearing (NH age-mates. Methods: Test of Language Development was administered to 30 pre-lingual, severe-to-profound CI children between the ages of 5 to 8. The obtained scores were compared to a Persian database from scores of normally hearing children with the same age range. Results: Results indicated that in spite of great advancements in different areas of language after hearing gain, CI children still lag behind their hearing age-mates in almost all aspects of language skills. Discussion: Based on the results, it is suggested that children with average or above average cognitive skills who use CI have the potential to produce and understand language comparable to their normally hearing peers.

Joseph K Gona

Full Text Available To explore parents' and professionals' perceived causes and treatment of Autism Spectrum Disorders (ASD on the Kenyan Coast.In-depth interviews and focus group discussions using guiding questions were utilized in data collection. One hundred and three participants, who included parents of children with ASD, special needs teachers, clinicians, and social workers from diverse cultural background, participated in this study. The interviews and focus groups were recorded, transcribed verbatim and then translated to English. Themes were generated using content analysis.Preternatural causes were mentioned and included evil spirits, witchcraft, and curses. Biomedical causes comprised infections, drug abuse, birth complications, malnutrition, and genetic related problems. Treatment varied from traditional and spiritual healing to modern treatment in health facilities, and included consultations with traditional healers, offering prayers to God, and visits to hospitals.The results suggest that regardless of cultural backgrounds, people on the Kenyan Coast have similar views on perceived causes and treatment of ASD. These findings provide valuable conceptual understanding for professionals when planning and implementing community based rehabilitation interventions targeting children with ASD within a local context.

Full Text Available Vision rehabilitation in adults with low vision, even in children, is achieved with special devices, called low vision aids, LVA. The aim of the study is to determine the degree of visual function in amblyopic children and daily activities that are best related to those of normally sighted peers with normal visual acuity. The subjects were divided into two groups, matched 1:1 by age and gender: the first group consisted of 19 amblyopic children, and the second one consisted of 19 children with normal visual acuity. The questionnaire used to assess visual ability was Cardiff Visual Ability Questionnaire for Children (CVAQC, a reliable instrument for measuring visual ability in children with low vision. The study was conducted in the only rehabilitation center for amblyopic children in this region, so this is also a pioneer study. The overall result of CVAQC in amblyopic children was 1.287 log vs.-2.956, representing statistically significantly poorer visual ability in comparison to peers without vision deficit (p˂0.005. Amblyopic children function best in entertainment activities, especially in listening music (-2.31 log; as for sport, these children report swimming to be their favourite activity (-0.99 log. In the field of education they show best results in language acquisition (-0.79 log and the worst in mathematics (3.13 log. The greatest problem is reading small print texts books (2.61 log. Low vision children have poorer result of visual function in comparison to their peers with normal visual acuity. A precise deficit assessment in the most important spheres of life can be determined by using the questionnaires, so the rehabilitation can be rightly chosen.

There have been several reports as to normal CT in children. However, they included children with convulsions as normal subjects. In our experience, children with convulsions have an enlargement of the subdural space in the frontal region. Therefore, we studied CT in children without convulsions. Of the 10,000 patients examined with EMI 1000 or EMI 1010 at Kyoto Univ. Hospital from 1976 to 1979, 110 children could be classified into the following types according to their symptoms: 1) Type-1 head injury, without abnormalities in CT resulting from this injury, 2) non-migraining headaches, and 3) others without CT abnormalities who were routinely examined. Previous studies have shown that the enlargement of the subdural space in the frontal region was not abnormal under one year. However, the present study has shown that it was not dilated in children without convulsions. We stressed the usefulness of our newly calculated basal cistern index, because the SD was small and could be readily indentified (this index was under 0.29 in most cases; their SD's were 0.04 in those under one year and 0.02 over one year). The other data were not so different from those of previous studies.

Full Text Available Inexpensive and efficacious interventions that avert childhood deaths in sub-Saharan Africa have failed to reach effective coverage, especially among the poorest rural sectors. One particular example is insecticide-treated bed nets (ITNs. In this study, we present repeat observations of ITN coverage among rural Kenyan homesteads exposed at different times to a range of delivery models, and assess changes in coverage across socioeconomic groups.We undertook a study of annual changes in ITN coverage among a cohort of 3,700 children aged 0-4 y in four districts of Kenya (Bondo, Greater Kisii, Kwale, and Makueni annually between 2004 and 2006. Cross-sectional surveys of ITN coverage were undertaken coincidentally with the incremental availability of commercial sector nets (2004, the introduction of heavily subsidized nets through clinics (2005, and the introduction of free mass distributed ITNs (2006. The changing prevalence of ITN coverage was examined with special reference to the degree of equity in each delivery approach. ITN coverage was only 7.1% in 2004 when the predominant source of nets was the commercial retail sector. By the end of 2005, following the expansion of heavily subsidized clinic distribution system, ITN coverage rose to 23.5%. In 2006 a large-scale mass distribution of ITNs was mounted providing nets free of charge to children, resulting in a dramatic increase in ITN coverage to 67.3%. With each subsequent survey socioeconomic inequity in net coverage sequentially decreased: 2004 (most poor [2.9%] versus least poor [15.6%]; concentration index 0.281; 2005 (most poor [17.5%] versus least poor [37.9%]; concentration index 0.131, and 2006 with near-perfect equality (most poor [66.3%] versus least poor [66.6%]; concentration index 0.000. The free mass distribution method achieved highest coverage among the poorest children, the highly subsidised clinic nets programme was marginally in favour of the least poor, and the commercial

NORMAL VALUES AND FACTORS AFFECTING FUNCTIONAL REACH TEST IN SAUDI ARABIA SCHOOL CHILDREN WITH TYPICAL DEVELOPMENT

Directory of Open Access Journals (Sweden)

Hatem A. Emara

2015-10-01

Full Text Available Background: The most critical feature of motor development is the ability to balance the body in sitting or standing. Impaired balance limits a child’s ability to recover from unexpected threats to stability. The functional reach test (FRT defines the maximal distance an individual is able to reach forward beyond arm’s length in a standing position without loss of balance, taking a step, or touching the wall. The Purpose of this study was to establish the normal values for FRT in Saudi Arabia school children with typical development and to study the correlation of anthropometric measures with FRT values. Methods: This cross-sectional study was conducted in Almadinah Almonawarah, Kingdom of Saudi Arabia. A total of 280 children without disabilities aged 6 to 12 years were randomly selected. Functional reach was assessed by having subjects extend their arms to 90 degrees and reach as far forward as they could without taking a step. Reach distance was recorded by noting the beginning and final position of the subject's extended arm parallel to a yard stick attached to the wall. Three successive trials of FRT were performed and the mean of the three trials was calculated. Pearson product moment correlation was used to examine the association of FR to age, and anthropometric measures. Results: Normal mean values of FR ranged from 24.2cm to 33.95cm. Age, height and weight significantly correlate with FRT. Conclusion: The FRT is a feasible test to examine the balance of 6-12 year-old children. FRT may be useful for detecting balance impairment, change in balance performance over time.

Only limited and conflicting information is available regarding the relationship between socioeconomic status (SES) and narrative abilities. Besides, the role fathers' SES plays in the development of their children's narrative abilities has never been investigated. The aim of this study was to analyze the relationship between fathers' and mothers' SES and narrative abilities of their children assessed with the Italian version of the Bus Story Test (I-BST). A total of 505 normally developing Italian children were enrolled in the study. Information regarding parents' educational level and employment was collected for each child. Narrative abilities were evaluated using the I-BST. The relationships between parents' employment, educational level, and I-BST scores were analyzed by univariate and multivariate regression analysis. In univariate analysis, both fathers' and mothers' education and employment were associated with most I-BST subscale scores, especially when higher educational and employment levels were contrasted with the lowest educational and employment levels. In multiple regression analysis, significant associations were found only between the fathers' working status and educational level and I-BST subscale scores. Parental education and employment might impact narrative abilities of children. When both fathers' and mothers' SES variables are considered together, only fathers' education and working status seemed to be associated with I-BST scores. © 2016 S. Karger AG, Basel.

Polyunsaturated fatty acids are essential nutrients for the normal development of the brain. We investigated the associations between plasma polyunsaturated fatty acids and cognition in normal weight and overweight children. The study recruited 386 normal weight children and 58 overweight children aged six to eight years and blood samples were drawn after a 12-hour fast. We assessed plasma polyunsaturated fatty acids using gas chromatography, cognition using Raven's Coloured Progressive Matrices, and overweight and obesity using the age-specific and sex-specific cut-offs from the International Obesity Task Force. The data were analysed by linear regression analyses adjusted for age and sex. Higher proportions of eicosapentaenoic acid in plasma triacylglycerols (β = 0.311, p = 0.020, p = 0.029 for interaction) and docosahexaenoic acid in plasma triacylglycerols (β = 0.281, p = 0.038, p = 0.049 for interaction) were both associated with higher Raven's scores in overweight children but not in normal weight children. Higher eicosapentaenoic acid to arachidonic acid ratios in triacylglycerols (β = 0.317, p = 0.019) and phospholipids (β = 0.273, p = 0.046) were directly associated with the Raven's score in overweight children but not in normal weight children. These findings suggest that increasing the consumption of fish and other sources of eicosapentaenoic acid and docosahexaenoic acid may improve cognition among overweight children. ©2016 Foundation Acta Paediatrica.

2013-08-01

Full Text Available BACKGROUND: The optimization of gait performance is an important goal in the rehabilitation of children with cerebral palsy (CP who present a prognosis associated with locomotion. Gait analysis using videos captured by digital cameras requires validation. OBJECTIVE: To evaluate the validity of a method that involves the analysis of videos captured using a digital camera for quantifying the temporal parameters of gait in toddlers with normal motor development and children with CP. METHOD: Eleven toddlers with normal motor development and eight children with spastic hemiplegia who were able to walk without assistive devices were asked to walk through a space contained in the visual field of two instruments: a digital camera and a three-dimensional motion analysis system, Qualisys Pro-Reflex. The duration of the stance and swing phases of gait and of the entire gait cycle were calculated by analyzing videos captured by a digital camera and compared to those obtained by Qualisys Pro-Reflex, which is considered a highly accurate system. RESULTS: The Intraclass Correlation Coefficient (ICC demonstrated excellent agreement (ICC>0.90 between the two procedures for all measurements, except for the swing phase of the normal toddlers (ICC=0.35. The standard error of measurement was less than 0.02 seconds for all measures. CONCLUSIONS: The results reveal similarities between the two instruments, suggesting that digital cameras can be valid instruments for quantifying two temporal parameters of gait. This congruence is of clinical and scientific relevance and validates the use of digital cameras as a resource for helping the assessment and documentation of the therapeutic effects of interventions targeted at the gait of children with CP.

Full Text Available Objectives: Phonemic awareness skills have a significant impact on children speech and language. The purpose of this study was investigating the phonemic awareness skills of children with cochlear implant and normal hearing peers in primary school. Methods: phonemic awareness subscales of phonological awareness test were administered to 30 children with cochlear implantation at the first to sixth grades of primary school and 30 children with normal hearing who were matched in age with cochlear implant group. All of children were between 6 to 11 years old. Children with cochlear implant had at least 1 to 2 years of implant experience and they were over 5 years when they receive implantation. Children with cochlear implant were selected from Special education centers in Tehran and children with normal hearing were recruited from primary schools in Tehran. The phonemic awareness skills were assessed in both groups. Results: The results showed that the Mean scores of phonemic awareness skills in cochlear implant children were significantly lower than children with normal hearing (P<.0001. Discussion: children with cochlear implant, despite Cochlear implantation prosthesis, had lower performance in phonemic awareness when compared with normal hearing children. Therefore, due to importance of phonemic awareness skills in learning of literacy skills, and defects of these skills in children with cochlear implant, these skills should be assessed carefully in children with cochlear implant and rehabilitative interventions should be considered.

Children with congenital heart disease (CHD) commonly experience delayed growth. Because growth and development are closely related, both should be considered when a child's progress is examined. This paper reports a study to evaluate and compare the growth and development of preschool children with CHD to those of normal preschool children. The heights and weights of 42 preschool children with CHD and 116 normal preschool children were compared with standard growth curves. Differences in development of personal and social skills, fine motor skills and adaptability, language, and gross motor skills were evaluated. Developmental skills were assessed using the Denver Developmental Screening Test II. A significant difference was found in both body height (P motor sections (P development. Learning about the growth and developmental differences between children with CHD and normal children may help parents of the former to detect problems associated with delayed growth and development earlier. These children and their families should have the opportunity to participate in a long-term, follow-up programme that provides information and encourages developmental progress. The results could serve as a reference for those in both clinical and community workers who provide nursing care to children with CHD.

Full Text Available Objective: Linguistic and metalinguistic knowledge are the effective factors for definitional skills. This study investigated definitional skills both content and form in children with specific language impairment. Materials and Method: The participants were 32 Children in two groups of 16 SLI and 16 normal children, matched with age, sex and educational level. The SLI group was referred from Learning Difficulties Centers and Zarei Rehabilitation Center in Tehran, as well as the control group who was selected by randomized sampling from normal primary schools. The stimuli were 14 high frequency nouns from seven different categories. The reliability was calculated by interjudge agreement and the validity was assessed by content. Data was analyzed using independent T-test. Results: There were significant differences between mean scores of content and form of the definitional skills in two groups. The mean and SD scores of the content of word definition were M= 45.87, SD=12.22 in control group and M=33.18, SD= 17.60 for SLI one, out of possible 70 points (P= 0.025. The mean and SD scores of the form of word definition were M= 48.87, SD= 9.49 in control group and M= 38.18, SD= 12.85 for SLI one, out of 70 points (P= 0.012. Conclusion: Based on the results, it was concluded that, language problems of the SLI children may not let them semantic represention in order to form and present a complete process of word definition. Although this skill in children with SLI is inadequate, all the definitions given by SLI children were consistent with the categories of content and form of word definition used in this study. Therefore, an exact planning and intervention by speech and language pathologist can be effective for this skill. Linguistic intervention especially in semantic and grammatical aspects not only improves the definition of familiar words but also it might be useful for the definition of new words, consequently lead to educational and

Full Text Available The objective of the study was to compare the attention-deficit/ hyperactivity, and substance abuse disorders background in the parents of children with attention-deficit/ hyperactivity disorder (ADHD, and the parents of normal children. The available sampling method was used to choose 400 parents of children (200 parents of children with ADHD and 200 parents of normal children, the ages of children were 6-18 years old. The data were collected through the Schedule for Affective Disorders and Schizophrenia (SADS for parents and the Kiddy Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL, Connors Adult ADHD Rating Scale (CAARS and the Wender Utah Rating Scale (WURS for adult ADHD. The results were analyzed by using SPSS-17 software, based on two-variable Chi-Square and t-tests.and P value in all disorders were equals to P<0.05. The results indicated that substance abuse in parents of children with ADHD is 21% more prevalent, and parents of children with ADHD compared to parents of normal children have 2% ADHD, 9% attention deficit disorder, and 1% hyperactivity disorder more in their background. Therefore, we conclude that there exists a significant difference between the above mentioned disorders in the parents of children with ADHD, and parents of normal children. The high prevalence rate of disorders and background of ADHD in families of individuals with ADHD shows the probability of effect of inheritance in the disorder. Also, it shows that parents of children with ADHD have more substance abuse and history of ADHD in their background.

Street children turn to sex-work to survive.

Science.gov (United States)

1995-08-01

The Kenyan government currently deports tourists who are caught with child prostitutes and charges the children with prostitution. A harder treatment of foreigners caught with child prostitutes may soon emerge. The Undugu Society in Kenya, an organization working with street children, welcomes such changes. It teaches children practical skills, e.g., tailoring and carpentry. The Society has four schools and sponsors 1000 children to attend school or workshops. It sends social workers into the slums to counsel and gain the trust of street children as well as to encourage them to attend workshops. The Society has workshops on HIV transmission and emphasizes behavior change rather than condom use. Kenyan law prohibits adults from having sex with a child less than 18 years old. Juvenile courts deal with children caught engaging in solicitation of customers and/or prostitution. Children found guilty go to children's homes for rehabilitation into mainstream society. More and more countries of sex-tourists are punishing tourists who engage in sexual intercourse with minors in Kenya. Fear that high-profile cases will harm the multi-million-dollar tourist industry as well as lack of state resources makes Kenya reluctant to prosecute tourists. In 1994, most of Nairobi's 40,000 street children were engaged in prostitution. The leading centers of child prostitution are all tourist areas: Nairobi, Mombasa, Malindi, Lamu, and Diani. 80% of pornographic material in Kenya features children. Kenyan taxi drivers, tour guides, and hotel workers serve as middlemen in child prostitution. Urban poverty forces many children on to the streets. Rural children sent to urban areas to work as maids or servants in a rich house are often sexually abused. They then escape to the streets. Many child prostitutes come from poor families and have low literacy and no practical skills. AIDS orphans also become prostitutes to survive.

Full Text Available In today’s globalized world, businesses look to expand to have a global presence. Restaurant businesses have expanded internationally using franchising. This study sought to determine the critical success factors (CSFs of a franchised restaurant system entering the Kenyan market from the franchisors’ perspective. It sought to establish how franchisors define, identify, and evaluate success. This study provides a theoretical framework that helps to understand the background of why organizations seek to expand using franchising method and consequently the CSFs of franchised restaurants entering the Kenyan market. The study used qualitative methodology with the use of in-depth interviews for collecting data. The results yielded CSFs from the franchisors’ perspective. As revealed by the study, the CSFs include brand power/concept, competitive environment, government policies, distance management, cultural appeal, excellent selection of franchisees, good site/location selection, good relationship with the franchisees, and proper contract management. These findings can be used by restaurant franchises that seek to establish successful businesses in the Kenyan market and other similar regional markets. The Africa franchise partners may also find some useful information from this article as they seek to set up the Franchise Association of Kenya. Other franchise businesses may also benefit from some aspects of the study.

Full Text Available Background and Aim: Stress is associated with life satisfaction and also development of some physical diseases. Birth of a disabled child with mental or physical disability (especially deaf or blind children, impose an enormous load of stress on their parents especially the mothers. This study compared stress levels of mothers with hearing impaired children and mothers of normal children or with other disabilities.Methods: In this study, cluster random sampling was performed in Karaj city. 120 mothers in four groups of having a child with mental retardation, low vision, hearing impairment and with normal children were included. Family inventory of life events (FILE of Mc Cubbin et al. was used to determine stress level in four groups of mothers.Results: The results of this research indicated a significant difference (p<0.05 between stress levels of mothers with hearing impaired children and mothers of other disabled and normal children in subscales of intra-family stress, finance and business strains, stress of job transitions, stress of illness and family care and family members "in and out''. There was no difference between compared groups in other subscales.Conclusion: Since deafness is a hidden inability, the child with hearing impairment has a set of social and educational problems causing great stress for parents, especially to mother. In order to decrease mother’s stress, it is suggested to provide more family consultation, adequate social support and to run educational classes for parents to practice stress coping strategies.

Variant anatomy of renal arteries is important in renal transplant, vascular reconstruction, and uroradiological procedures. The variations show ethnic and population differences. Data from Africans are scarce and altogether absent for Kenyans. To describe patterns of origin, trajectories and branching of renal arteries in a Kenyan population. Descriptive cross-sectional study conducted in the Department of Human Anatomy, University of Nairobi. Three hundred and fifty six kidneys from 178 cadavers and postmortem specimens were used in the study. Aorta, renal arteries and kidneys were exposed by dissection. Number, trajectories, level of branching, number of branches and point of entry into the kidney were recorded. Data was analyzed using SPSS version 16.0, and presented using macrographs, tables, and bar charts. Additional arteries occurred in 14.3% of the cases. In 82.4% of these, there was one additional artery. Fifty nine point five per cent of the double renal arteries were parallel and 7.1% crossed. Of the 305 single arteries, 76.4% showed hilar, 21.6% prehilar and 2% intraparenchymal branching. In the hilar branching, ladder type was present in 65% and fork type in 35%. Bifurcation and trifurcation were present in 59.6% and 33.1% respectively. Polar arteries were present in 16.9% cases. Over 14% of the Kenyan population may have additional renal arteries while more than 20% show early branching. Several trajectories and hilar branching patterns exist which renal transplant surgeons and radiologists should be aware of to avoid inadvertent vascular injury.

Methods: This tool-making and non-experimental research was conducted in two stages. In the first stage the proper story was selected and recorded after evaluation of its content validity. In the second stage this test material was administered to a total 181 normal children (97 girls and 84 boys randomly chosen from the population of preschool and primary school children of Tehran (District 5, aged 5-8 years in four age groups to evaluate the reliability of test in order to develop the Persian version of the ANL test and assess its changes during the growth. Lawshe’s method and Cronbach’s alpha coefficient were used to assess the content validity and reliability of the test, respectively. Mann– Whitney U test was used to examine gender differences, and Kruskal-Wallis test was to examine age differences. Results: Test-retest correlation of 0.74 indicated acceptable reliability of the test. Significant differences were found between most of different age groups for the ANL mean scores (P0.05. Conclusion: The study results indicated good validity and reliability of the Persian version of the ANL test in children. Therefore this test can be useful in designing classrooms suitable for 5-8 year-old children of both genders.

Limited pediatric data exist examining the trend and predictors of antitissue transglutaminase (atTG) normalization over time in children with celiac disease (CD). We aimed to evaluate time to normalization of atTG in children after CD diagnosis, and to assess for independent predictors affecting this duration. A retrospective chart review was completed in pediatric patients with CD diagnosed from 2007 to 2014 at the Stollery Children's Hospital Celiac Clinic (Edmonton, Alberta, Canada). The clinical predictors assessed for impact on time to atTG normalization were initial atTG, Marsh score at diagnosis, gluten-free diet compliance (GFDC), age at diagnosis, sex, ethnicity, medical comorbidities, and family history of CD. Kaplan-Meier survival analysis was completed to assess time to atTG normalization, and Cox regression to assess for independent predictors of this time. A total of 487 patients met inclusion criteria. Approximately 80.5% of patients normalized atTG levels. Median normalization time was 407 days for all patients (95% confidence interval [CI: 361-453]), and 364 days for gluten-free diet compliant patients (95% CI [335-393]). Type 1 diabetes mellitus (T1DM) patients took significantly longer to normalize at 1204 days (95% CI [199-2209], P normalization time. GFDC was a significant predictor of earlier normalization (OR = 13.91 [7.86-24.62], P normalization. Patients with T1DM are less likely to normalize atTG levels, with longer normalization time. Additional research and education for higher-risk populations are needed.

Full Text Available BACKGROUND Global developmental delay/intellectual disability are on a rise in children in the present time. Ocular and visual anomalies are frequently associated with it of which refractive errors are the most frequent. This if goes unnoticed leads to strabismus and amblyopia. MATERIALS AND METHODS This study aims to assess the prevalence of refractive error, strabismus and amblyopia among children with normal development or global developmental delay/intellectual disability attending ophthalmology OPD at KLES Hospital, Belagavi. Case records of all 200 new patients less than or equal to 12 years of age group who attended KLES, Dr. Prabhakar Kore Hospital between January 2015 and December 2015 were retrospectively reviewed. RESULTS The male:female ratio was 1.22:1. Out of the total evaluated 200 cases, 130 cases were with normal development and 70 with GDD/ID. Refractive errors were 85%, whereas the cases of amblyopia was 45.50% and strabismus 39.50%. Amblyopia with refractive error having GDD/ID was stastically significant as compared to amblyopia with refractive error having normal development (p=0.001. CONCLUSION Refractive error was the most common ocular disorder seen. Refractive error with amblyopia is more in children with GDD/ID as compared to normal children. Owing to the high percentage of visual anomalies, ophthalmological referral becomes essential in children with developmental anomalies.

Sub-optimal physical growth has been suggested as a key pathway between the effect of environmental risk and developmental outcome. To determine if anthropometric status mediates the relation between socioeconomic status and psychomotor development of young children in resource-limited settings. A cross-sectional study design was used. A total of 204 (105 girls) children from two resource-limited communities in the Coast Province, Kenya. The mean age of these children was 29 months (SD = 3.43; range: 24-35 months). Psychomotor functioning was assessed using a locally developed and validated measure, the Kilifi Developmental Inventory. A significant association was found between anthropometric status (as measured by weight-for-age, height-for-age, mid-upper arm circumference, and head circumference) and psychomotor functioning and also between socioeconomic status and anthropometric status; no direct effects were found between socioeconomic status and developmental outcome. The models showed that weight, height and to a lesser extent mid-upper arm circumference mediate the relation between socioeconomic status and developmental outcome, while head circumference did not show the same effect. Among children under 3 years living in poverty, anthropometric status shows a clear association with psychomotor development while socioeconomic status may only have an indirect association.

To measure and compare hand function for children with normal hand development, congenital hand differences (CHD), and neuromuscular disease (NMD) using a function test with touch screen technology designed as an iPhone application. We measured touch screen hand function in 201 children including 113 with normal hand formation, 43 with CHD, and 45 with NMD. The touch screen test was developed on the iOS platform using an Apple iPhone 4. We measured 4 tasks: touching dots on a 3 × 4 grid, dragging shapes, use of the touch screen camera, and typing a line of text. The test takes 60 to 120 seconds and includes a pretest to familiarize the subject with the format. Each task is timed independently and the overall time is recorded. Children with normal hand development took less time to complete all 4 subtests with increasing age. When comparing children with normal hand development with those with CHD or NMD, in children aged less than 5 years we saw minimal differences; those aged 5 to 6 years with CHD took significantly longer total time; those aged 7 to 8 years with NMD took significantly longer total time; those aged 9 to 11 years with CHD took significantly longer total time; and those aged 12 years and older with NMD took significantly longer total time. Touch screen technology has becoming increasingly relevant to hand function in modern society. This study provides standardized age norms and shows that our test discriminates between normal hand development and that in children with CHD or NMD. Diagnostic III.

Kinematic differentiation of prosodic categories in normal and disordered language development.

Science.gov (United States)

Goffman, Lisa

2004-10-01

Prosody is complex and hierarchically organized but is realized as rhythmic movement sequences. Thus, observations of the development of rhythmic aspects of movement can provide insight into links between motor and language processes, specifically whether prosodic distinctions (e.g., feet and prosodic words) are instantiated in rhythmic movement output. This experiment examined 4-7-year-old children's (both normally developing and specifically language impaired) and adults' productions of prosodic sequences that were controlled for phonetic content but differed in morphosyntactic structure (i.e., content vs. function words). Primary analyses included kinematic measures of rhythmic structure (i.e., amplitude and duration of movements in weak vs. strong syllables) across content and function contexts. Findings showed that at the level of articulatory movement, adults produced distinct rhythmic categories across content and function word contexts, whereas children did not. Children with specific language impairment differed from normally developing peers only in their ability to produce well-organized and stable rhythmic movements, not in the differentiation of prosodic categories.

2016-03-01

Full Text Available The proportion of women working in the formal sector in Sub-Saharan Africa has increased in recent years. The kinship networks are weakening, leading to a decline in the traditional forms of support for child care and housework. This study examined the work–family balance options of women working in Kenyan universities within the context of changing national domestic workers’ legislation. Data were collected by use of surveys in two universities. Results showed that as the cost of hiring domestic workers increased, women became indifferent in their choice between employing domestic workers and using daycare centers. Women with older children who employed day domestic workers were more likely to use daycare centers than women with younger children who employed live-in domestic workers. Women with young children in preschool and primary school found their universities less accommodating in helping them balance work and family demands. Employers perceived that the domestic workers’ legislation led to a drop in morale among domestic workers, and demands of pay raises as they became choosier and more inclined to search for better paying employers. It also resulted in a shift of work–family balance strategy for women who opted to hire domestic workers on an “as-needed” or “weekend basis.” Some women stopped hiring them altogether and instead started taking their young children to daycare centers. Cost and affordability determined the use of domestic workers. These women suggested that their employers should increase their job flexibility and put up subsidized daycare centers.

Here we report on the vaccine's safety and tolerability. The experimental design was a Phase 2b, two-centre, double-blind (observer- and participant-blind, randomised (1∶1 ratio controlled trial. Three doses of study or control (rabies vaccines were administered intramuscularly at 1 month intervals. Solicited adverse events (AEs were collected for 7 days after each vaccination. There was surveillance and reporting for unsolicited adverse events for 30 days after each vaccination. Serious adverse events (SAEs were recorded throughout the study period which lasted for 14 months after dose 1 in Korogwe, Tanzania and an average of 18 months post-dose 1 in Kilifi, Kenya. Blood samples for safety monitoring of haematological, renal and hepatic functions were taken at baseline, 3, 10 and 14 months after dose 1. A total of 894 children received RTS,S/AS01(E or rabies vaccine between March and August 2007. Overall, children vaccinated with RTS,S/AS01(E had fewer SAEs (51/447 than children in the control group (88/447. One SAE episode in a RTS,S/AS01(E recipient and nine episodes among eight rabies vaccine recipients met the criteria for severe malaria. Unsolicited AEs were reported in 78% of subjects in the RTS,S/AS01(E group and 74% of subjects in the rabies vaccine group. In both vaccine groups, gastroenteritis and pneumonia were the most frequently reported unsolicited AE. Fever was the most frequently observed solicited AE and was recorded after 11% of RTS,S/AS01(E doses compared to 31% of doses of rabies vaccine. The candidate vaccine RTS,S/AS01(E showed an acceptable safety profile in children living in a malaria-endemic area in East Africa. More data on the safety of RTS,S/AS01(E will become available from the Phase 3 programme.

Objective: To study the developmental characters of the normal mandible in growing children. Methods: Twenty growing children undergoing skeletal scintigraphic study for isolated bone disease other than bones of the head and neck at hospital and turned out with normal results finally were studied. The 99 Tc m -MDP uptakes in the mandibular condyle, ramus, body and the fourth lumbar vertebra in these cases were quantitated and a ratio of the uptake in the three mandibular regions to that in the fourth lumbar vertebra was obtained. Results: The analysis results showed that the 99 Tc m -MDP uptake ratios of the three mandibular regions decreased in linear fashion with age increasing and leveled off after age of 20. The regression equations are: the mandibular condyle, Y-circumflex = -0.052 2X + 1.792 8; the mandibular ramus, Y-circumflex = -0.015 1X + 0.766 7; the mandibular body, Y-circumflex = -0.014 2X + 0.741 0. There was no significant difference of the 99 Tc m -MDP uptake ratio between the two sides of the mandible and between the male and female. Conclusion: The results suggest that the ideal time to undergo orthognathic surgery should be at the age of 20 or so if the circumstance of the deformity is not quite clear

Full Text Available Background: This cross-sectional study was carried out to compare balance performance between children with cochlear implants and post-aural aid and normal children. Methods: The present study was done on 67 severe to profound hearing impaired children. Of these, 21 children with an average age of 7 years and 4 months (±1.7 wore cochlear implant, 46 children with an average age of 7 years and 7 months (±1.7 wore post-aural aid and 60 children with an average 8 years and one month (±11 months were considered as a control group. All of the children were tested with the 9-stage balance subtest of Bruininks-Oseretsky Test of Motor Proficiency2 (BOT2. Results: The mean total BOT2 score of hearing impaired children was significantly lower than the normal group (P≤0.001. The mean total BOT2 score among children with cochlear implant, post-aural aids and normal group showed that cochlear implant group significantly performed weaker than the other two groups (P≤0.001. Conclusion: Hearing impaired children particularly children with cochlear implant are exposed to the risk of balance deficit. Hearing impaired children specially those who wear cochlear implants must be screened for vestibular hypofunction.

Growth and development after hematopoietic cell transplant in children.

Science.gov (United States)

Sanders, J E

2008-01-01

Hematopoietic cell transplantation (HCT) following high-dose chemotherapy or chemoradiotherapy for children with malignant or nonmalignant hematologic disorders has resulted in an increasing number of long-term disease-free survivors. The preparative regimens include high doses of alkylating agents, such as CY with or without BU, and may include TBI. These agents impact the neuroendocrine system in growing children and their subsequent growth and development. Children receiving high-dose CY or BUCY have normal thyroid function, but those who receive TBI-containing regimens may develop thyroid function abnormalities. Growth is not impacted by chemotherapy-only preparative regimens, but TBI is likely to result in growth hormone deficiency and decreased growth rates that need to be treated with synthetic growth hormone therapy. Children who receive high-dose CY-only have normal development through puberty, whereas those who receive BUCY have a high incidence of delayed pubertal development. Following fractionated TBI preparative regimens, approximately half of the patients have normal pubertal development. These data demonstrate that the growth and development problems after HCT are dependent upon the preparative regimen received. All children should be followed for years after HCT for detection of growth and development abnormalities that are treatable with appropriate hormone therapy.

Full Text Available Attention deficit hyperactivity disorder (ADHD is the most common behavioral problem during childhood and in school-aged children. Various projection drawings have been designed for assessing children's personality and psychological disorders including the tests of draw a person (DAP and draw a family (DAF. We aimed to compare the differences between typically developing children and children with ADHD using these tests.In this case-control study, all the 9-10 year-old boy students studying at the third and fourth grades were enrolled from schools in the 2nd educational district of Shiraz, south of Iran. Eighty students were then selected and enrolled into the ADHD group and the control group. The Diagnostic and Statistical Manual of Mental Disorders, 4th edition- text Revised (DSM-IV-TR, and the Child Symptoms Inventory were used to diagnose the children with ADHD. We evaluated and analyzed impulsiveness, non-impulsiveness, emotional problems and incompatibility indices in the DAP and DAF tests in each group.A significant difference was found in the indices of incompatibility and emotional problems, impulsiveness, non-impulsiveness and DAF between typically developing children and those with ADHD. The mean (±SD total scores of the above mentioned indices in the ADHD group were 19.79(±2.94, 12.31(±1.84, 5.26(±2.29 and 5.89(±2.13, respectively (P<0.001. The corresponding figures for these indices in the normal group were 12.11(±4.74, 5.63(±2, 10.36± (2.33 and 2.88(±2.13, respectively (P<0.001.Significant differences were obtained between the control group and children with ADHD using these two drawing tests. The rate of impulsivity and emotional problems indices in drawings of children with ADHD was markedly more common than those of the typically developing children. This suggests the need for further assessment to screen ADHD.

CT assessment of normal splenic size in children

International Nuclear Information System (INIS)

Prassopoulos, P.; Cavouras, D.

1994-01-01

The size of the normal spleen was estimated by CT in 153 children, examined with indication unrelated to splenic disease. In each patient the width, thickness, length and volume of the spleen were calculated. Measurements were also normalized to the transverse diameter of the body of the first lumbar vertebra. The spleen underwent significant growth during the first 4 years of life and reached maximum size at the age of 13. There were no differences in splenic volume between boys and girls. Splenic thickness correlated best with normal splenic volume. The strongest correlation was also found between splenic thickness and volume in a group of 45 children with clinically evident splenomegaly. Splenic thickness, an easy-to-use measurement, may be employed in everyday practice to represent splenic volume on CT. (orig.)

Full Text Available BACKGROUND Parents experience psychological trauma if they recognise that their children are having conduct disorder, which is unacceptable to the society and against the social norms. The intensity of depression in parents having children with conduct disorder is included in this study. MATERIALS AND METHODS Exploratory research was used in this study as the method of study. A sample was selected from parents having children with conduct disorder reported in various psychiatric settings in Kerala, India, and also from parents having normal children. Random sampling was used for selecting the sample. All the parents of children diagnosed with conduct disorder in the age group of 6 to 12 reported in the psychiatric settings on a random day is selected as sample. Mann-Whitney U test was used for statistical analysis. RESULTS Depression in parents affect their skills in caregiving, support to their children, nurturance and it will affect proper development of children physically and mentally. Similarly, conduct disorder in children will affect their parents mental and social functioning and their life functioning and the parents maybe suffering from depression. Mothers of children with conduct disorders are reported to have exhibit more depressed and they show very poor parenting skills and negative interactions with their children compared to normal mothers. Parents having children with conduct disorder did have higher intensity of depression compared to parents having normal children. CONCLUSION The study hopes to make contributions in identifying the intensity of depression in parents having children with conduct disorder and it’s serious and least recognised impact on their parents. The study will also help to find out the areas in which parents need intervention and to decide which type of therapy will be more helpful to the family as a whole. Identifying and understanding the relevant and feasible components of therapy can then facilitate

Brown adipose tissue (BAT) is identified in mammals as an adaptive thermogenic organ for modulation of energy expenditure and heat generation. Human BAT may be primarily composed of brown-in-white (BRITE) adipocytes and stimulation of BRITE may serve as a potential target for obesity interventions. Current imaging studies of BAT detection and characterization have been mainly limited to PET/CT. MRI is an emerging application for BAT characterization in healthy children. To exploit Dixon and diffusion-weighted MRI methods to characterize cervical-supraclavicular BAT/BRITE properties in normal-weight and obese children while accounting for pubertal status. Twenty-eight healthy children (9-15 years old) with a normal or obese body mass index participated. MRI exams were performed to characterize supraclavicular adipose tissues by measuring tissue fat percentage, T2*, tissue water mobility, and microvasculature properties. We used multivariate linear regression models to compare tissue properties between normal-weight and obese groups while accounting for pubertal status. MRI measurements of BAT/BRITE tissues in obese children showed higher fat percentage (P < 0.0001), higher T2* (P < 0.0001), and lower diffusion coefficient (P = 0.015) compared with normal-weight children. Pubertal status was a significant covariate for the T2* measurement, with higher T2* (P = 0.0087) in pubertal children compared to prepubertal children. Perfusion measurements varied by pubertal status. Compared to normal-weight children, obese prepubertal children had lower perfusion fraction (P = 0.003) and pseudo-perfusion coefficient (P = 0.048); however, obese pubertal children had higher perfusion fraction (P = 0.02) and pseudo-perfusion coefficient (P = 0.028). This study utilized chemical-shift Dixon MRI and diffusion-weighted MRI methods to characterize supraclavicular BAT/BRITE tissue properties. The multi-parametric evaluation revealed evidence of morphological differences in brown

One of the electroencephalographic (EEG) patterns that can be mistaken for paroxysmal clinical activity, when not taken into account and especially in children, is hypnagogic hypersynchrony (HH). This consists in generalised, paroxysmal, synchronic, symmetrical, slow, high voltage waves lasting 2 8 seconds, which appear in drowsiness and in stage I. It was observed that this pattern often appeared in children with learning disability (LD). AIMS. To correlate clinical data with the presence of HH during sleep in normal children and those with LD. We assessed 180 children between the ages of 6 12 years with normal neurological development, 130 of which suffered LD and 50 who did not have LD. EEG was performed with sleep deprivation, following the International Federation of Clinical Neurophysiology guidelines. The presence or absence of HH, together with its characteristics, was assessed. Of the children with LD, 35.38% displayed HH and of the children without LD, only 4% displayed HH. Since the characteristics of HH in the children with LD were different to previous descriptions, we put forward criteria with which to evaluate those differences. HH appeared more often in children with LD than in normal children. Qualitative, quantitative (p< 0.05) and morphological changes were found in the paroxysmal activity of HH during the stages of sleep in children with LD.

Children's grammatical categories of verb and noun: a comparative look at children with specific language impairment (SLI) and normal language (NL).

Skipp, Amy; Windfuhr, Kirsten L; Conti-Ramsden, Gina

2002-01-01

The study investigated the development of grammatical categories (noun and verb) in young language learners. Twenty-eight children with specific language impairment (SLI) with a mean language age of 35 months and 28 children with normal language (NL) with a mean language age of 34 months were exposed to four novel verbs and four novel nouns during 10 experimental child-directed play sessions. The lexical items were modelled with four experimentally controlled argument structures. Both groups of children showed little productivity with syntactic marking of arguments in the novel verb conditions. Thus, both groups of children mostly followed the surface structure of the model presented to them, regardless of the argument they were trying to express. Therefore, there was little evidence of verb-general processes. In contrast, both groups used nouns in semantic roles that had not been modelled for them. Importantly, however, children with SLI still appeared to be more input dependent than NL children. This suggests that children with NL were working with a robust noun schema, whereas children with SLI were not. Taken together, the findings suggest that neither group of children had a grammatical category of verb, but demonstrated a general knowledge of the grammatical category of noun. These findings are discussed in relation to current theories of normal and impaired language development.

The pattern of pneumatisation and normal width of the maxillary sinus in 191 Nigerian infants and children whose age range was 6 months to 14 years was determined. Fifty-four percent of children with no respiratory tract or sinus infection had opaque maxillary sinus. A figure of 44.5% was obtained amongst children with suspected bronchopneumonia. Only 41.5% of suspected cases of sinusitis, acute and chronic middle ear disease had opaque sinus. The highest rate of sinus opacity was seen in children under 2 years who were asymptomatic. The mean maximal width of normally aerated sinus was 8.74 mm for children under 2 years, 16.5 mm for 3-6 years, 21.5 mm for 7-11 years and 25 mm for children 12 years and above. We conclude that maxillary sinus opacity in our experience is an unreliable index for the diagnosis of sinusitis in children. (orig.)

The pathogenesis of asthma in the context of excess body weight may be distinct from asthma that develops in normal weight children. The study's objective was to explore the biology of asthma in the context of obesity and normal weight status using genetic methodologies. Associations between asthma and SNPs in 49 genes were assessed, as well as, interactions between SNPs and overweight status in child participants of the Greater Cincinnati Pediatric Clinic Repository. Asthma was significantly associated with weight (OR = 1.38; P = 0.037). The number of genes and the magnitude of their associations with asthma were notably greater when considering overweight children alone vs normal weight and overweight children together. When considering weight, distinct sets of asthma-associated genes were observed, many times with opposing effects. We demonstrated that the underlying heterogeneity of asthma is likely due in part to distinct pathogenetic pathways that depend on preceding/comorbid overweight and/or allergy. It is therefore important to consider both obesity and asthma when conducting studies of asthma. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full text: As part of a larger study looking at gastric emptying times in cystic fibrosis, we assessed the normal range of gastric emptying in a control group of children. Thirteen children (8 girls, 5 boys) aged 4-15 years (mean 10) were studied. Excluded were children with a history of relevant gastrointestinal medical or surgical disease, egg allergy or medication affecting gastric emptying. Imaging was performed at 08.00 h after an overnight fast. The test meal was consumed in under 15 min and comprised one 50 g egg, 80 g commercial pancake mix, 10 ml of polyunsaturated oil, 40 ml of water and 30 g of jam. The meal was labelled with 99 Tc m -macroaggregates of albumin. Water (150 ml) was also consumed with the test meal. One minute images of 128 x 128 were acquired over the anterior and posterior projections every 5 min for 30 min, then every 15 min until 90 min with a final image at 120 min. Subjects remained supine for the first 60 min, after which they were allowed to walk around. A time-activity curve was generated using the geometric mean of anterior and posterior activity. The half emptying time ranged from 55 to 107 min (mean 79, ± 2 standard deviations 43-115). Lag time (time for 5% to leave stomach) ranged from 2 to 26 min (mean 10). The percent emptied at 60 min ranged from 47 to 73% (mean 63%). There was no correlation of half emptying time with age. The normal reference range for a test meal of pancakes has been established for 13 normal children

The study population included all mothers of children with developmental, emotional, and disruptive behavior disorders, and mothers with normal children in Hamadan (a city in Iran. 240 mothers (4 groups include 60 mothers were chosen based on simple random sampling. Family inventory of life events and changes Mc Cubbin, Patterson & Wilson was used for assessing participants. The results showed that maternal stress in mothers with children who have diagnosis of disruptive behavior disorders were significantly more than of mothers of children with developmental disorders, emotional and mothers of normal children. The present study showed that disruptive behavior disorders in children have a greater impact on their mothers. So, we suggest approved psychological interventions for helping mothers of children with psychological problems, particularly children with external disorders.

The Pediatric Quality of Life (PedsQL inventory is a questionnaire to assess quality of life of the healthy and ill children. Objective To compare quality of life in children with cancer and their normal siblings, and to compare quality of life in those with hematologic malignancies to those with solid tumors. Methods A cross-sectional study was conducted among 5-to-18- year-olds at the Hematology-Oncology Division at Haji Adam Malik Hospital, Medan, North Sumatera, from May to July 2012. The case group (subjects with cancer filled the PedsQL 3.0 and 4.0 questionnaires, while the control group (normal siblings filled only the PedsQL 4.0 questionnaire. Independent T-test was used to compare the quality of life between children with cancer and their normal siblings. Results There were 46 children in each group. The PedsQL 4.0 results in children with cancer and their normal siblings, and PedsQL 3.0 between hematology malignant and solid cancer were as follows: physical function 36.9 vs. 80.7, respectively (95%CI of differences -52.639 to -34.990; P= 0.0001, emotional function 40.4 vs. 69.3, respectively (95%CI of differences -35.912 to -21.914; P=0.0001, social function 71.5 vs. 93.9, respectively (95%CI of differences - 29.238 to -15.587; P=0.0001, school function 20.7 vs. 74.2, respectively (95%CI of differences - 62.124 to -44.832; P=0.0001, and total score 42.1 vs. 79.3, respectively (95%CI of differences - 43.066 to -31.344; P=0.0001. School function was the most affected parameter in children with cancer compared to their normal siblings. Conclusion There is a significant difference in quality of life between children with cancer and their normal siblings, for all four parameters examined by the PedsQL inventory. However, there are no significant differences in quality of life between children with hematologic malignancy and those with

Plantar pressure distribution during walking is affected by several gait factors, most especially the foot progression angle which has been studied in children with neuromuscular diseases. However, this relationship in normal children has only been reported in limited studies. The purpose of this study is to clarify the correlation between foot progression angle and plantar pressure distribution in normal children, as well as the impacts of age and sex on this correlation. This study retrospectively reviewed dynamic pedobarographic data that were included in the gait laboratory database of our institution. In total, 77 normally developed children aged 5-16 years who were treated between 2004 and 2009 were included. Each child's footprint was divided into 5 segments: lateral forefoot, medial forefoot, lateral midfoot, medial midfoot, and heel. The percentages of impulse exerted at the medial foot, forefoot, midfoot, and heel were calculated. The average foot progression angle was 5.03° toe-out. Most of the total impulse was exerted on the forefoot (52.0%). Toe-out gait was positively correlated with high medial (r = 0.274; P plantar pressure as part of the treatment of various foot pathologies. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available The purpose of this paper is to begin a dialogue of developing a integrated and comprehensive system for youth in Kenya by identifying factors impacting the creation of a youth development system and exploring recommendations supporting and advancing such a system.  The results of two collaborative assessments of the needs and strengths of Kenyan youth and the youth-serving programs based on the perspectives of practitioners, policy-makers, and scholars of youth-development are presented. The study was framed from the perspective of a systems approach to youth development in Kenya (Bronfenbrenner & Morris, 2006; Overton & Lerner, 2012. Osgood (2012 identifies four steps for developing a systems approach for serving the needs of youth: (1 self-assessment, (2 goal identification, (3 planning, and (4 networking. The first step, self-assessment, was initiated through a SWOT analysis with two different groups of youth development professionals across a 2-year period (2014-2015.  The 2014 SWOT analysis presented the strengths, weaknesses, opportunities, and threats related to developing a youth development system from a national level, whereas the 2015 SWOT analysis focused on these same factors but from a more local level of youth development programs and services.  The results of these two analyses are presented and initial recommendations for building a more integrated and comprehensive youth development system in Kenya are presented.  The need for further input and investigation is also discussed.   This is a correction to the original article.

Full Text Available Background and Aim: Having healthy non-handicapped children plays a major role in mental health of the family and decreases family and society's costs. While consanguineous marriage could lead to expression of recessive genes and a variety of handicaps including deafness, the aim of present study was to scrutinize the prevalence of consanguineous marriage among parents of deaf and normal children as well as its relationship with deafness.Methods: In this study, 467 couples parenting normal children were selected by cluster sampling from elementary, guidance and high schools of Ardabil city and 423 couples parenting disabled children were selected non-randomly among which 130 had deaf children. Descriptive statistics was used to determine the prevalence of consanguineous marriage and chi-square test to compare prevalence of consanguineous marriage among parents of normal and deaf children.Results: Descriptive analyses showed that 80 out of 130 (61.54% parents who had deaf children have had consanguineous marriage. Furthermore data analysis demonstrated that prevalence of consanguineous marriage was significantly higher among parents of deaf children (p<0.001.Conclusion: Consanguineous marriage plays a major role in expression of recessive genes and could lead to development of various handicaps including deafness. Increasing couples' awareness about consequences of consanguineous marriage and conducting genetic counseling are indispensable.

Full Text Available Objective: Study of the children psychomotor development, is and interdisciplinary interest among medical and rehabilitation specialist. The psychomotor development is mostly dependent on normal ontogenetically evolution of the brain, thus it is reasonable that any defects in this complicated process would be able to cause irreversible cognitive, sensory and motor dysfunction. In addition to mental deficiency in Mental Retarded (MR children, some other notable defects in motor abilities including gross and fine movement and equilibrium also exist in these children. Hemispheric dominancy or lateralization is an important stage in normal brain development which thought to be affected in MR children, and thus affects the outcome of rehabilitation treatment for these children. The present research work is designed to study functional cerebral lateralization between mentally retarded children having mental age of 5 to 6 years old and normal ones of the same age. Materials & Methods: By using the Neurological Developmental Questionnaire of Delacatom the functional lateralization parameters including footedness, handedness, and eye and ear preference were considered in this study. Results: Statistical analysis of the results showed significant differences in above mentioned parameters among MR and normal children of the same age. Conclusion: On the bases of these results, we believe that different pattern of lateralization in MR children could affect the rehabilitation management and should be noted in therapeutic plan.

This study examines the differences in bone mineral density between normal-weight children and children with overweight or obesity. A systematic review and meta-analysis of observational studies (published up to 22 June 2016) on the differences in bone mineral density between normal-weight children and overweight and obese children was performed. Results were pooled when possible and mean differences (MDs) were calculated between normal-weight and overweight and normal-weight and obese children for bone content and density measures at different body sites. Twenty-seven studies, with a total of 5,958 children, were included. There was moderate and high quality of evidence that overweight (MD 213 g; 95% confidence interval [CI] 166, 261) and obese children (MD 329 g; 95%CI [229, 430]) have a significantly higher whole body bone mineral content than normal-weight children. Similar results were found for whole body bone mineral density. Sensitivity analysis showed that the association was stronger in girls. Overweight and obese children have a significantly higher bone mineral density compared with normal-weight children. Because there was only one study included with a longitudinal design, the long-term impact of childhood overweight and obesity on bone health at adulthood is not clear. © 2017 World Obesity Federation.

Full Text Available CONTEXT AND OBJECTIVE: Oral narrative is a means of language development assessment. However, standardized data for deaf patients are scarce. The aim here was to compare the use of narrative competence between hearing-impaired and normal-hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one moderately to profoundly bilaterally hearing-impaired children (cases and 21 normal-hearing children without language abnormalities (controls, matched according to sex, age, schooling level and school type, were studied. A board showing pictures in a temporally logical sequence was presented to each child, to elicit a narrative, and the child's performance relating to narrative structure and cohesion was measured. The frequencies of variables, their associations (Mann-Whitney test and their 95% confidence intervals was analyzed. RESULTS: The deaf subjects showed poorer performance regarding narrative structure, use of connectives, cohesion measurements and general punctuation (P < 0.05. There were no differences in the number of propositions elaborated or in referent specification between the two groups. The deaf children produced a higher proportion of orientation-related propositions (P = 0.001 and lower proportions of propositions relating to complicating actions (P = 0.015 and character reactions (P = 0.005. CONCLUSION: Hearing-impaired children have abnormalities in different aspects of language, involving form, content and use, in relation to their normal-hearing peers. Narrative competence was also associated with the children's ages and the school type.

The purposes of the present study were to establish the Standard-Chinese version of Lexical Neighborhood Test (LNT) and to examine the lexical and age effects on spoken-word recognition in normal-hearing children. Six lists of monosyllabic and six lists of disyllabic words (20 words/list) were selected from the database of daily speech materials for normal-hearing (NH) children of ages 3-5 years. The lists were further divided into "easy" and "hard" halves according to the word frequency and neighborhood density in the database based on the theory of Neighborhood Activation Model (NAM). Ninety-six NH children (age ranged between 4.0 and 7.0 years) were divided into three different age groups of 1-year intervals. Speech-perception tests were conducted using the Standard-Chinese monosyllabic and disyllabic LNT. The inter-list performance was found to be equivalent and inter-rater reliability was high with 92.5-95% consistency. Results of word-recognition scores showed that the lexical effects were all significant. Children scored higher with disyllabic words than with monosyllabic words. "Easy" words scored higher than "hard" words. The word-recognition performance also increased with age in each lexical category. A multiple linear regression analysis showed that neighborhood density, age, and word frequency appeared to have increasingly more contributions to Chinese word recognition. The results of the present study indicated that performances of Chinese word recognition were influenced by word frequency, age, and neighborhood density, with word frequency playing a major role. These results were consistent with those in other languages, supporting the application of NAM in the Chinese language. The development of Standard-Chinese version of LNT and the establishment of a database of children of 4-6 years old can provide a reliable means for spoken-word recognition test in children with hearing impairment.

Full Text Available Ontogenesis of the psychomotor development in group of congenital blind children has its own specifics. Visual defect is influenced by many things. In the period from birth to two years of age occur in children, significant changes in cognitive, psychomotor and social development. Compared with the normal sighted population go the development of congenital blind children in all these areas slower. Visual deprivation also influenced on development of body posture. More important is whether the development proceeds in stages that correspond to the development of normal vision child. If development proceeds in the right direction is the temporal aspect criterion rather orientation. For blind children is also important to strengthen the ability to correctly identify their own body through somatognosy. Stereognosy in turn determines the degree of contact with the outer world and focus it in relation to the physical schema.

Full Text Available Background Motor behavior is an essential aspect of child development, and usually assessed in terms of age of achievement of motor milestone. The early detection of infants experiencing subtle delays in motor maturation can allow early intervention in developmental problems. Intervention can be more effective if delays are identified early. In order to facilitate the identification of early delays, the Center of Nutrition and Foods Research and Development in Bogor has designed a simple tool to monitor the child (aged 3 to 18 months motor development. Objective To develop an observable of normal gross motor maturation for use to detect deviance or motor delay. Methods A total of 2100 healthy children, aged 3-18 months, from high socio-economic group, in urban and suburban areas, were studied. Body length, weight and motor development were measured on all children. Gross motor development was measured 17 pre selected milestones: lie, sit, crawl, creep, stand Mth assistance, walk with assistance, stand alone, walk alone, and run. Results There were no differences between males and females in the comparison of attainment motor maturation therefore a sex combined curve was developed. Conclusion The curve of normal motor milestone development can be used as a tool to evaluate motor development over time, and/or as a child development card for use in primary health care.

This study compared rCBF pattern in normal adult and normal children using statistical parametric mapping (SPM). The purpose of this study was to determine distribution pattern not seen visual analysis in both groups. Tc-99m ECD brain SPECT was performed in 12 normal adults (M:F=11:1, average age 35 year old) and 6 normal control children (M:F=4:2, 10.5{+-}3.1y) who visited psychiatry clinic to evaluate ADHD. Their brain SPECT revealed normal rCBF pattern in visual analysis and they were diagnosed clinically normal. Using SPM method, we compared normal adult group's SPECT images with those of 6 normal children subjects and measured the extent of the area with significant hypoperfusion and hyperperfusion (p<0.001, extent threshold=16). The areas of both angnlar gyrus, both postcentral gyrus, both superior frontal gyrus, and both superior parietal lobe showed significant hyperperfusion in normal adult group compared with normal children group. The areas of left amygdala gyrus, brain stem, both cerebellum, left globus pallidus, both hippocampal formations, both parahippocampal gyrus, both thalamus, both uncus, both lateral and medial occipitotemporal gyrus revealed significantly hyperperfusion in the children. These results demonstrated that SPM can say more precise anatomical area difference not seen visual analysis.

Renal length offers important information to detect or follow-up various renal diseases. The purpose of this study was to determine the kidney length of normal Korean children in relation to age, height, weight, body surface area (BSA), and body mass index (BMI). Children between 1 month and 15 years of age without urological abnormality were recruited. Children below 3rd percentile and over 97th percentile for height or weight were excluded. Both renal lengths were measured in the prone position three times and then averaged by experienced radiologists. The mean length and standard deviation for each age group was obtained, and regression equation was calculated between renal length and age, weight, height, BSA, and BMI, respectively. Renal length was measured in 550 children. Renal length grows rapidly until 24 month, while the growth rate is reduced thereafter. The regression equation for age is: renal length (mm) = 45.953 + 1.064 x age (month, ≤ 24 months) (R2 = 0.720) or 62.173 + 0.203 x age (months, > 24 months) (R2 = 0.711). The regression equation for height is: renal length (mm) = 24.494 + 0.457 x height (cm) (R2 = 0.894). The regression equation for weight is: renal length (mm) = 38.342 + 2.117 x weight (kg, ≤18 kg) (R2 = 0.852) or 64.498 + 0.646 x weight (kg, > 18 kg) (R2 = 0.651). The regression equation for BSA is: renal length (mm) = 31.622 + 61.363 x BSA (m2, ≤ 0.7) (R2 = 0.857) or 52.717 + 29.959 x BSA (m2, > 0.7) (R2 = 0.715). The regression equation for BMI is: renal length (mm) = 44.474 + 1.163 x BMI (R2 = 0.079). This study provides data on the normal renal length and its association with age, weight, height, BSA and BMI. The results of this study will guide the detection and follow-up of renal diseases in Korean children

Home fortification powders containing iron and other micronutrients have been recommended by World Health Organisation to prevent iron deficiency anaemia in areas of high prevalence. There is evidence, however, that home fortification at this iron dose may cause gastrointestinal adverse events including diarrhoea. Providing a low dose of highly absorbable iron (3 mg iron as NaFeEDTA) may be safer because the decreased amount of iron in the gut lumen can possibly reduce the burden of these adverse effects whilst resulting in similar or higher amounts of absorbed iron. To show non-inferiority of home fortification with 3 mg iron as NaFeEDTA compared with 12.5 mg iron as encapsulated ferrous fumarate, with haemoglobin response as the primary outcome. 338 Kenyan children aged 12-36 months will be randomly allocated to daily home fortification with either: a) 3 mg iron as NaFeEDTA (experimental treatment), b) 12.5 mg iron as encapsulated ferrous fumarate (reference), or c) placebo. At baseline, after 30 days of intervention and within 100 days post-intervention, blood samples will be assessed for primary outcome (haemoglobin concentration), iron status markers, Plasmodium parasitaemia and inflammation markers. Urine and stool samples will be assessed for hepcidin concentrations and inflammation, respectively. Adherence will be assessed by self-reporting, sachet counts and by an electronic monitoring device. If daily home fortification with a low dose of iron (3 mg NaFeEDTA) has similar or superior efficacy to a high dose (12.5 mg ferrous fumarate) then it would be the preferred choice for treatment of iron deficiency anaemia in children.

Full Text Available Objective: This research determined oral stereognosis (form recognition and spent time to recognize in normal children in north and south of Tehran city to use it in assessment and therapy of oral senses and speech in children with articulation disorders. Materials & Methods: This research was done in 200 children who were 6 & 7 years old and normal in Tehran city. 20 items with different shapes were used and children were wanted to recognize the shapes which were put in their mouth and they should choice one of three shapes located in front of them. Responses and the spent time were calculated. Results: The mean scores of form recognition in children of 6 years old is 17/34 and in children of 7 years old is 17/59. There was no significant difference between them in their scores (P=0.31. In addition, the time of formation diagnosis in 6 years old children is 2/67s (seconds and in 7 years old children is 2/82s, there was no significant difference between them (P=0.11.The northern city children responded slower than the other group (P=0.000. The only statistically significant score between two sexes was the time of formation recognition which was shorter in girls relative to the boys (P=0.043. Conclusion: Based on this study, a significant correlation could not be found in ability of oral stereognosis in 6 and 7 years old children. But in south of city children can recognize faster than children in northern city. Based on importance of this sense in speech, we suggest normalization of it in different ages.

Social conversational skills are a salient aspect of early pragmatic development in young children. These skills include two different abilities, assertiveness and responsiveness. This study investigated the development of these abilities in early implanted children and their relationships with lexical development and some language-sensitive variables. Prospective, observational, nonrandomized study. Participants included 28 children with congenital profound sensorineural hearing loss. The mean age at device activation was 13.3 months (standard deviation [SD] ±4.2). The Social-Conversational Skills Rating Scale was used to evaluate assertiveness and responsiveness. The MacArthur-Bates Communicative Development Inventory (Words and Sentences form) was used to analyze the lexical development. The device experience was 12 months for each child, and the mean age at testing was 25.9 months (SD ±4.6). Assertiveness and responsiveness scores were within the normal range of normal-hearing age-matched peers. Age at cochlear implant activation exerted a significant impact, with the highest scores associated to the youngest patients. The residual correlations between assertiveness and responsiveness with the lexical development were positive and strongly significant (r = 0.69 and 0.73, respectively). Preoperative hearing threshold demonstrated an associated significant coefficient on the assertiveness score. Age at diagnosis and maternal education level were not correlated with the social conversational skills. Early-implanted children developed social conversational skills that are similar to normal-hearing peers matched for age 1 year after device activation. Social conversational skills and lexical development were strongly correlated, but the present study design cannot specify the direction of this relationship. Children with better preoperative residual hearing exhibited better assertive ability. 4 Laryngoscope, 126:2098-2105, 2016. © 2015 The American Laryngological

Photovoltaic module quality in the Kenyan solar home systems market

International Nuclear Information System (INIS)

Duke, R.D.; Jacobson, A.; Kammen, D.M.

2002-01-01

As one of the largest unsubsidized markets for solar home systems (SHSs) in the world, Kenya represents a promising model for rural electrification based on private purchases of clean decentralized photovoltaic technologies. Small amorphous-silicon modules dominate the market and most brands provide high quality and affordable service. Product quality varies widely, however, and the public has limited capacity to distinguish among competing brands. This imposes direct hardships on households with the misfortune to purchase low-quality equipment, and it constrains sales as some customers refrain from purchasing solar equipment due to the associated performance uncertainty. This article analyzes market failure associated with photovoltaic module quality in the Kenyan SHS market and develops strategies to address the problem - emphasizing that similar quality problems may exist for other SHS components and in other markets. The principal conclusion is that domestic product testing with public disclosure represents an inexpensive low-risk strategy, but it may prove inadequate. Mandatory product quality standards based on international testing regimes (e.g. IEC standards), augmented with a basic domestic testing option, would provide stronger assurance, but the risks associated with this intervention suggest caution. An emerging multilateral SHS market support effort (PVMTI) should ensure quality for the credit-based sales it promotes in Kenya; however, the long-term impact of this approach is not yet clear and it is unlikely to address quality problems associated with the unsubsidized sales-based markets for SHSs. Finally, fee-for-service models would decisively address quality problems, but launching this model in the Kenyan market would likely require large subsidies. (author)

To measure the mean size of the various portions of the corpus callosum in normal Korean children, using MR imaging. Our subjects were 166 children (male : female=100 : 66) aged under 15 whose findings on MR imaging and neurologic examination were normal. Using midsagittal T1-weighted imaging, we measured the length of the brain and corpus callosum, the height of the latter, and the thickness of its genu body, transitional zone and splenium. The measurements were statistically analysed according to age and sex. Brain length and the size of the various portions of the corpus callosum tended to increase relatively rapidly during the first three years of life, but the rate of growth tended to decrease according to age. The mean lenght of the brain and corpus callosum and the mean thickness of the splenium of the corpus callosum did not differ according to sex. The mean thickness of the genu, body and transitional zone of the corpus callosum was greater in males than in females. The ratio of the length of the corpus callosum to the anteroposterior diameter of the brain was significantly greater in females than in males (alpha=0.05). Using MR imaging, we measured the mean sizes of the various portions of the corpus callosum in normal children;these values may provide a useful basis for determing changes occurring in its structure

Ninety children, aged from 2 month to 3 years, with thymomegaly and 25 aged-matched controls were studied. Most children with thymomegaly had disturbances of psychomotor development. Depending on their types, the cohort of children was stratified into 4 subgroups: 1st - 36 patients (40%) with schizotypal signs; 2nd - 30 hyperactive children (33%); 3rd - 19 children with hyperthymia signs (21%); 4th - 5 normal children (6%). The deviations of locomotion and psychiatric development were correlated with the extent of thymus enlargement and activation of innate and adaptive immunity.

Stoever, B.

1986-01-01

Standards of heart size, i.e. heart diameters and heart volume of normal children aged 4-15 years were obtained. In all cases requiring exact heart size determination, heart volume calculation is mandatory in children as well as in adults. Statistical work to date has provided precise calculation of heart volume plain films in the upright position. Additional plain films in prone position are unnecessary because no evident orthostatic influence on heart volume in children can be found. Percentiles of normal heart volume related to body weight representing the best correlation to the individual data are given as well as percentiles related to age. Furthermore ratios of normal vessel size to the height of the 8sup(th) thoracic vertebral body, measured on the same plain film, are given. In addition the ratio of upper to lower lung vessel size is calculated. These ratios are useful criteria in estimating normal vessel size and also in cases with increased pulmonary venous pressure.

The aim of this study was to demonstrate and explore the ability of novel game-based perimetry to establish normal visual field thresholds in children. One hundred and eighteen children (aged 8.0 ± 2.8 years old) with no history of visual field loss or significant medical history were recruited. Each child had one eye tested using a game-based visual field test 'Caspar's Castle' at four retinal locations 12.7° (N = 118) from fixation. Thresholds were established repeatedly using up/down staircase algorithms with stimuli of varying diameter (luminance 20 cd/m 2 , duration 200 ms, background luminance 10 cd/m 2 ). Relationships between threshold and age were determined along with measures of intra- and intersubject variability. The Game-based visual field test was able to establish threshold estimates in the full range of children tested. Threshold size reduced with increasing age in children. Intrasubject variability and intersubject variability were inversely related to age in children. Normal visual field thresholds were established for specific locations in children using a novel game-based visual field test. These could be used as a foundation for developing a game-based perimetry screening test for children.

Full Text Available This study intended to take a biomechanical approach to understand the success of Kenyan distance runners. Anthropometric, gait and lower extremity strength characteristics of six elite Kenyan distance runners were analyzed. Stride frequency, relative stride length and ground contact time were measured at five running speeds (3.5 - 5.4 m/s using a motion capture system. Isometric knee extension and flexion torques were measured at six angles and hamstrings and quadriceps (H:Q ratios at three angular velocities were determined using an isokinetic dynamometer. These runners were characterized by a low body mass index (20.1 ± 1.8 kg·m- 2, low percentage body fat (5.1 ± 1.6% and small calf circumference (34.5 ± 2.3 cm. At all running speeds, the ground contact time was shorter (p < 0.05 during right (170 - 212 ms compared to left (177 - 220 ms foot contacts. No bilateral difference was observed in other gait or strength variables. Their maximal isometric strength was lower than other runners (knee extension: 1.4 - 2.6 Nm·kg-1, knee flexion: 1.0 - 1.4 Nm·kg-1 but their H:Q ratios were higher than athletes in other sports (1.03 ± 0.51 at 60o/s, 1.44 ± 0.46 at 120o/s, 1.59 ± 0.66 at 180o/s. The slim limbs of Kenyan distance runners may positively contribute to performance by having a low moment of inertia and thus requiring less muscular effort in leg swing. The short ground contact time observed may be related to good running economy since there is less time for the braking force to decelerate forward motion of the body. These runners displayed minor gait asymmetry, though the difference may be too small to be practically significant. Further investigations are needed to confirm whether the bilateral symmetry in strength and high H:Q ratios are related to genetics, training or the lack of injuries in these runners

The article reviews the current studies regarding language and cognitive development in children who are deaf. Deaf communicate orally and with sign language. 90 % of deaf children are born into hearing families and hearing parents in most cases do not know the sign language. Besides, hearing parents usually want for their child to become "normally" speaking. Most of the deaf children born into hearing families have very poor early communication. It is now well established that deaf children ...

2017-01-01

The purpose of the present study was to investigate Mandarin tone recognition in background noise in children with cochlear implants (CIs), and to examine the potential factors contributing to their performance. Tone recognition was tested using a two-alternative forced-choice paradigm in various signal-to-noise ratio (SNR) conditions (i.e. quiet, +12, +6, 0, and -6 dB). Linear correlation analysis was performed to examine possible relationships between the tone-recognition performance of the CI children and the demographic factors. Sixty-six prelingually deafened children with CIs and 52 normal-hearing (NH) children as controls participated in the study. Children with CIs showed an overall poorer tone-recognition performance and were more susceptible to noise than their NH peers. Tone confusions between Mandarin tone 2 and tone 3 were most prominent in both CI and NH children except for in the poorest SNR conditions. Age at implantation was significantly correlated with tone-recognition performance of the CI children in noise. There is a marked deficit in tone recognition in prelingually deafened children with CIs, particularly in noise listening conditions. While factors that contribute to the large individual differences are still elusive, early implantation could be beneficial to tone development in pediatric CI users.

"For me it's just normal" - Strategies of children and young people from rainbow families against de-normalization. The case of Slovenia and Germany.

Full Text Available The paper presents some findings from an international study called “School is out – Experiences of children from rainbow families in school” which explored how children and young people from rainbow families anticipate, experience and deal with schools as heteronormative spaces. In the research, the term de-normalisation was developed to describe the processes by which children with LGBT-identified parents are perceived and constructed as not normal, as classified beyond the ‘hetero-normative normality’, which is expressed through ‘othering’ by others, for example in interaction. To avoid, prevent or reduce the impacts of de-normalisation processes, the interviewed children and youth have developed different strategies which we present in two frames: one involving disclosure and concealment and the other involving verbalisations and justifications. Based on these insights and findings, the article also outlines ideas on the resilience factors against de-normalisation and emphasises the importance of children and youth not standing alone against it.

2002-01-01

To determine the mean liver CT numbers, and differences between liver and spleen, and liver and back muscle CT numbers in normal children, and to correlate the findings with sex and age. One hundred and five normal children aged 2-14 years underwent pre-contrast CT scanning. Mean CT numbers of the liver, spleen, and back muscles were calculated, as well as the differences in CT numbers between the liver and spleen (liver-spleen CT numbers), and between the liver-back muscle CT numbers were 70.22±6.51 HU, 53.28±3.57 HU, 17.13±6.57 HU, and 11.88±5.94 HU, respectively. Mean liver CT numbers and the difference between liver and back muscle CT numbers were not different by age. By sex, all the CT numbers did not vary according to age. The sex of a subject did not affect the CT number. The children's mean liver CT number was 70.22±6.51 HU and the difference between liver and spleen CT numbers was 17.13±6.57 HU. Younger children had higher liver CT and liver-spleen CT numbers than older children. No CT numbers varied according to sex

Literature describing stigmatizing attitudes towards people with mental illness by children in the developing world is lacking. Children's mental health issues in the Kenyan context are especially pertinent due to the increased likelihood of exposure to risk factors and the high prevalence of mental disorders. The objective of the current study was to examine socio-demographic factors associated with the endorsement of stigmatizing attitudes towards people with mental illness among Kenyan school children. We analyzed cross-sectional survey data from 4585 primary school-aged children in standards one through seven in the Eastern Province of Kenya. We examined relationships between the endorsement of stigmatizing attitudes and age, gender, district, religion, being in the standard appropriate for one's age, and parental employment status. Stigma scores decreased with increasing age (β = -0.83; 95 % CI = -0.99 to -0.67). Boys had higher stigma scores compared to girls (β = 1.55; 95 % CI = 0.86-2.24). Students from the rural district had higher average stigma scores as compared to those from the peri-urban district (β = 1.14; 95 % CI = 0.44-1.84). Students who were not in the standard appropriate for their age had lower stigma scores than those who were in the standard typical for their age (β = -1.60; 95 % CI = -2.43 to -0.77). Stigmatizing attitudes toward the mentally ill exist among primary school children in Kenya; thus, anti-stigma interventions are needed, and our findings highlight particular subgroups that could be targeted.

The dentate nuclei lie deep within the cerebellum and play a vital role in the pathways involved in fine motor control and coordination. They are susceptible to a variety of diseases. Some pathological processes preferentially affect the dentate nuclei, while concomitant basal ganglia or white matter involvement can be a striking finding in others. A familiarity with the normal appearance of the dentate nuclei at different ages in combination with the radiological distribution of pathology in the brain allows the paediatric radiologist to develop a logical approach to the interpretation of MR imaging of these deep cerebellar nuclei. In this article we review the normal appearance and MR features of the dentate nuclei, including changes that are seen with myelination. We describe the specific imaging characteristics of childhood diseases that involve the dentate nuclei, and develop a systematic approach to the differential diagnosis of dentate nucleus abnormalities on MR imaging.

This study investigated whether social modeling of palatable food intake might partially be explained by the direct imitation of a peer reaching for snack food and further, assessed the role of the children's own weight status on their likelihood of imitation during the social interaction. Real-time observations during a 10-min play situation in which 68 participants (27.9% overweight) interacted with normal-weight confederates (instructed peers) were conducted. Children's imitated and non-imitated responses to the confederate's food picking movements were compared using a paired sample t-test. In addition, the pattern of likelihood of imitation was tested using multilevel proportional hazard models in a survival analysis framework. Children were more likely to eat after observing a peer reaching for snack food than without such a cue [t (67) = 5.69, P imitation responses during a social interaction based on their weight status (HR = 2.6, P = 0.03, 95% CI = 1.09-6.20). Overweight children were almost twice as likely to imitate, whereas normal-weight children had a smaller chance to imitate at the end of the interaction. Further, the mean difference in the likelihood of imitation suggest that overweight children might be less likely to imitate in the beginning of the interaction than normal-weight children. The findings provide preliminary evidence that children's imitation food picking movements may partly contribute to social modeling effects on palatable food intake. That is, a peer reaching for food is likely to trigger children's snack intake. However, the influence of others on food intake is a complex process that might be explained by different theoretical perspectives.

Full Text Available To date, there has been no standardized approach to the assessment of aerobic fitness among children who harbor parasites. In quantifying the disability associated with individual or multiple chronic infections, accurate measures of physical fitness are important metrics. This is because exercise intolerance, as seen with anemia and many other chronic disorders, reflects the body's inability to maintain adequate oxygen supply (VO(2 max to the motor tissues, which is frequently linked to reduced quality-of-life in terms of physical and job performance. The objective of our study was to examine the associations between polyparasitism, anemia, and reduced fitness in a high risk Kenyan population using novel implementation of the 20-meter shuttle run test (20mSRT, a well-standardized, low-technology physical fitness test.Four villages in coastal Kenya were surveyed during 2009-2010. Children 5-18 years were tested for infection with Schistosoma haematobium (Sh, malaria, filaria, and geohelminth infections by standard methods. After anthropometric and hemoglobin testing, fitness was assessed with the 20 mSRT. The 20 mSRT proved easy to perform, requiring only minimal staff training. Parasitology revealed high prevalence of single and multiple parasitic infections in all villages, with Sh being the most common (25-62%. Anemia prevalence was 45-58%. Using multiply-adjusted linear modeling that accounted for household clustering, decreased aerobic capacity was significantly associated with anemia, stunting, and wasting, with some gender differences.The 20 mSRT, which has excellent correlation with VO(2, is a highly feasible fitness test for low-resource settings. Our results indicate impaired fitness is common in areas endemic for parasites, where, at least in part, low fitness scores are likely to result from anemia and stunting associated with chronic infection. The 20 mSRT should be used as a common metric to quantify physical fitness and compare sub

Comparison of home fortification with two iron formulations among Kenyan children: Rationale and design of a placebo-controlled non-inferiority trial

Full Text Available Introduction: Home fortification powders containing iron and other micronutrients have been recommended by World Health Organisation to prevent iron deficiency anaemia in areas of high prevalence. There is evidence, however, that home fortification at this iron dose may cause gastrointestinal adverse events including diarrhoea. Providing a low dose of highly absorbable iron (3 mg iron as NaFeEDTA may be safer because the decreased amount of iron in the gut lumen can possibly reduce the burden of these adverse effects whilst resulting in similar or higher amounts of absorbed iron. Objective: To show non-inferiority of home fortification with 3 mg iron as NaFeEDTA compared with 12.5 mg iron as encapsulated ferrous fumarate, with haemoglobin response as the primary outcome. Design: 338 Kenyan children aged 12–36 months will be randomly allocated to daily home fortification with either: a 3 mg iron as NaFeEDTA (experimental treatment, b 12.5 mg iron as encapsulated ferrous fumarate (reference, or c placebo. At baseline, after 30 days of intervention and within 100 days post-intervention, blood samples will be assessed for primary outcome (haemoglobin concentration, iron status markers, Plasmodium parasitaemia and inflammation markers. Urine and stool samples will be assessed for hepcidin concentrations and inflammation, respectively. Adherence will be assessed by self-reporting, sachet counts and by an electronic monitoring device. Conclusion: If daily home fortification with a low dose of iron (3 mg NaFeEDTA has similar or superior efficacy to a high dose (12.5 mg ferrous fumarate then it would be the preferred choice for treatment of iron deficiency anaemia in children.

Altered neural control of movement and musculoskeletal deficiencies are common in children with spastic cerebral palsy (SCP), with muscle weakness and contracture commonly experienced. Both neural and musculoskeletal deficiencies are likely to contribute to abnormal gait, such as equinus gait (toe-walking), in children with SCP. However, it is not known whether the musculoskeletal deficiencies prevent normal gait or if neural control could be altered to achieve normal gait. This study examined the effect of simulated muscle weakness and contracture of the major plantarflexor/dorsiflexor muscles on the neuromuscular requirements for achieving normal walking gait in children. Initial muscle-driven simulations of walking with normal musculoskeletal properties by typically developing children were undertaken. Additional simulations with altered musculoskeletal properties were then undertaken; with muscle weakness and contracture simulated by reducing the maximum isometric force and tendon slack length, respectively, of selected muscles. Muscle activations and forces required across all simulations were then compared via waveform analysis. Maintenance of normal gait appeared robust to muscle weakness in isolation, with increased activation of weakened muscles the major compensatory strategy. With muscle contracture, reduced activation of the plantarflexors was required across the mid-portion of stance suggesting a greater contribution from passive forces. Increased activation and force during swing was also required from the tibialis anterior to counteract the increased passive forces from the simulated dorsiflexor muscle contracture. Improvements in plantarflexor and dorsiflexor motor function and muscle strength, concomitant with reductions in plantarflexor muscle stiffness may target the deficits associated with SCP that limit normal gait.

US detection of a normal appendix can safely rule out appendicitis. However, there is a wide range of accuracy in detection of a normal appendix. To optimize US examination to detect the normal and the abnormal appendix according to the potential positions of the appendix. This prospective study included 107 children who underwent gray-scale US scanning. Noncompressive and compressive graded sonography was performed to detect normal and abnormal appendices according to their potential positions. The maximum transverse diameter of the appendices was measured. Of the 107 children examined, 56 had a histologic diagnosis of acute appendicitis. Sonography had a sensitivity of 100% and specificity of 98% for the diagnosis of appendicitis. A normal appendix was visualized in 44 (86.2%) of the 51 patients without acute appendicitis, and of these 44, 43 were true-negative and 1 was false-positive. Normal and abnormal appendices, respectively, were positioned as follows: 54.4% and 39.3% were mid-pelvic; 27.2% and 28.6% were retrocecal; 11.4% and 17.8% were deep pelvic; and 6.8% and 14.3% were abdominal. US scanning according to the potential positions of the appendix was useful in the detection of normal appendices in children suspected of having appendicitis. (orig.)

Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1(st) Department of Obstetrics and Gynecology, Medical University of Warsaw. The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group (P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

Full Text Available Most children have periods in their life where they reject familiar as well as non-familiar food items and this is often referred to as pickiness. The consequences of pickiness may be malnutrition and, if prolonged, potentially lower body weight. However, studies investigating the consequence of pickiness on subsequent changes in diet intake and weight are limited.To examine whether pickiness influences body mass index as well as diet intake over subsequent 15 months among obesity prone normal weight children aged 2-6 years.Data was obtained from the "Healthy Start" intervention study which included 271 children aged 2-6 years susceptible to overweight later in life. Information on pickiness was obtained from a parental questionnaire. Dietary habits were collected by 4-day dietary records filled in by the parents and height and weight were measured by trained health professionals and both measured twice over a 15 month period. Linear regression models were performed to assess the influence of pickiness on body mass index and diet with adjustments for possible confounders.No differences in mean BMI Z-score were seen between picky/non-picky (P = 0.68 and little picky/non-picky (P = 0.68 children at 15 month follow-up. Picky children had a lower intake of protein (P = 0.01 than non-picky children despite no differences in total energy intake (P = 0.74, or in the other macronutrients, or the intake of fruit and vegetables, though children being a little picky had a lower intake of starch compared to non-picky children (P = 0.05. Results were essentially similar before and after adjustment for key covariates.Our study showed that BMI Z-score after 15 months follow-up was similar for picky and non-picky children. Picky children seemed to develop a lower protein intake despite similar total energy intake and diet composition.

Teachers often use analogies in classroom settings to clarify new concepts for their students. However, analogies may inadvertently confuse the youngster who has difficulty identifying the one-to-one comparisons underlying them. Although analogical reasoning has been studied extensively in normal children, no information was available concerning this construct in children having a specific language impairment. Thus, it was unknown to what extent they might be deficient in analogical reasoning. Therefore, in the present study, 20 children ages 6-8 years (mean age = 7:6) having normal nonverbal intelligence but deficits in language comprehension were administered tasks of verbal and perceptual proportional analogical reasoning and a problem-solving task of functional analogical reasoning. Compared to a normal-language control group matched on the basis of chronological age and sex, the language-impaired group was deficient in all three tasks of analogical reasoning. However, when the factor of nonverbal intelligence was controlled statistically, the differences between the groups on each of the tasks were removed. Additional findings were that verbal proportional analogical reasoning was significantly correlated to perceptual proportional analogical reasoning and to functional analogical reasoning. Implications for assessment and intervention with young school-age language-impaired children are discussed.

Full text: Introduction and objective: Stunting is prevalent in young children in low-income countries, and has detrimental effects on psychomotor development and later working capacity. The objective of this study was to assess the association of body composition (fat-free mass and fat mass), breastfeeding and sex with stunting in Kenyan children aged 6 and 15 months Subjects and Method: As part of a nutrition trial conducted in Western Kenya, 449 six months old infants were recruited if MUAC≥11.5 cm. At six and 15 months of age, weight, recumbent length, skinfolds and mid-upper arm circumference (MUAC) were measured. Deuterium oxide dilution method was used to determine body fat and fat-free-mass. A predose saliva sample was taken prior to a dose to the infant of 0.5 g deuterium oxide per kg of body weight. Postdose saliva samples were taken after 2 and 3 hours, respectively. Deuterium enrichment was measured using Fourier Transformed Infrared Spectrophotometer. Linear regression was used to assess the association of sex, breastfeeding, fat-free mass index (FFMI), fat mass index (FMI) and body mass index (BMI) as correlates of stunting Results: At 6 months, males had FMI being 14.03 kg/m2 (95% CI 13.80; 14.26) compared to females at 13.67(95% CI 13.40; 13.94). At 15 months males had an FMI of 14.74(95% CI 14.48; 14.99) while females had 14.41(95% CI 14.18; 14.64). At age 6 and 15 months, females had a lower -0.45 (95% CI -2.37; 1.46) kg/m2 and -0.36 (95% CI -0.59;-0.13) kg/m2 FFMI compared to girls, respectively. Stunting was not associated with body composition at neither 6 nor 15 months. Those who stopped breastfeeding before 15 months (11.1%) had a 0.01(95% CI 0.002; 0.02) kg/m2 lower FFMI when they reached 15 months. Conclusion: Longer duration of breastfeeding was associated with higher FFMI in early infancy in resource poor settings .Stunting was associated with lower FMI at the age of 6 months but not at 15 months. Wasting was associated with a deficit

The stress hormone cortisol is vital to survival, and a disturbed circadian rhythm can be deleterious to health. However, little is known about cortisol levels in healthy children. The aim of this study was to examine cortisol levels in relation to body mass index (BMI), age and sex. Salivary samples were collected in early morning, late morning and evening, on four consecutive days, from 342 children aged 6-12 years using Salivette(®) tubes. Samples were analysed using a commercial enzyme immunoassay (EIA). School nurses measured the children's height and weight, and these measurements were used to calculate their BMI. The children displayed a circadian rhythm in cortisol secretion, with morning zeniths and evening nadirs. Average cortisol levels in early morning, late morning and evening were significantly lower in overweight and obese children than in their normal weight counterparts. Cortisol levels did not vary significantly with age or sex. Our findings may suggest cortisol suppression in overweight and obese children. We found no evidence that sex or age influences cortisol levels. These findings highlight the need for further research on the relationship between stress and obesity in children. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Several recent investigations support the use of frequency modulation (FM) systems in children with normal hearing and auditory processing or listening disorders such as those diagnosed with auditory processing disorders, autism spectrum disorders, attention-deficit hyperactivity disorder, Friedreich ataxia, and dyslexia. The American Academy of Audiology (AAA) published suggested procedures, but these guidelines do not cite research evidence to support the validity of the recommended procedures for fitting and verifying nonoccluding open-ear FM systems on children with normal hearing. Documenting the validity of these fitting procedures is critical to maximize the potential FM-system benefit in the above-mentioned populations of children with normal hearing and those with auditory-listening problems. The primary goal of this investigation was to determine the validity of the AAA real-ear approach to fitting FM systems on children with normal hearing. The secondary goal of this study was to examine speech-recognition performance in noise and loudness ratings without and with FM systems in children with normal hearing sensitivity. A two-group, cross-sectional design was used in the present study. Twenty-six typically functioning children, ages 5-12 yr, with normal hearing sensitivity participated in the study. Participants used a nonoccluding open-ear FM receiver during laboratory-based testing. Participants completed three laboratory tests: (1) real-ear measures, (2) speech recognition performance in noise, and (3) loudness ratings. Four real-ear measures were conducted to (1) verify that measured output met prescribed-gain targets across the 1000-4000 Hz frequency range for speech stimuli, (2) confirm that the FM-receiver volume did not exceed predicted uncomfortable loudness levels, and (3 and 4) measure changes to the real-ear unaided response when placing the FM receiver in the child's ear. After completion of the fitting, speech recognition in noise at a -5

The study aimed to evaluate the growth and development of institutionalized children from 0-6 years old. It had a descriptive, transversal and quantitative approach, and was held in a shelter from the Bureau of Labor and Social Development of the Government of the State of Ceará, in the months of March and April 2011. The sample comprised 44 children. It the sample prevailed male children (59.1%), aged 24 to 72 months (56.8%) and with time of sheltering more than one year (72.7%). It was found that the children were in the normal range of nutrition; however, 65.9% of children did not achieve at least one of the development milestones proposed by the Ministry of Health. The study suggests a reflection on how children living in shelters are being assisted by the health team, making it necessary follow up their growth and development, in order to intervene on the alterations.

Normal weight obesity is defined as having excessive body fat, but normal BMI. Even though previous research revealed that excessive body fat in children inhibited their physical activity and decreased motor performance, there has been only little evidence about motor performance of normal weight obese children. This study aims to establish whether normal weight obese pre-school children aged 3-6 years will have a significantly worse level of fundamental motor skills compared to normal weight non-obese counterparts. The research sample consisted of 152 pre-schoolers selected from a specific district of Prague, the Czech Republic. According to values from four skinfolds: triceps, subscapula, suprailiaca, calf, and BMI three categories of children aged 3-6 years were determined: A) normal weight obese n = 51; B) normal weight non-obese n = 52; C) overweight and obese n = 49. The Movement Assessment Battery for Children (MABC-2) was used for the assessment of fundamental motor skills. Normal weight obese children had significantly higher amount of adipose tissue p < 0.001 than normal weight non-obese children but the same average BMI. Moreover, normal weight obese children did not have significantly less amount of subcutaneous fat on triceps and calf compared to their overweight and obese peers. In majority of MABC-2 tests, normal weight obese pre-schoolers showed the poorest performance. Moreover, normal weight obese children had significantly worse total standard score = 38.82 compared to normal weight non-obese peers = 52.27; p < 0.05. In addition, normal weight obese children had a more than three times higher frequency OR = 3.69 CI95% (1.10; 12.35) of severe motor deficit performance ≤ 5 th centile of the MABC-2 norm. These findings are strongly alarming since indices like BMI are not able to identify normal weight obese individual. We recommend verifying real portion of normal weight obese children as they are probably in higher risk of health and motor

The aim of this study was to estimate the prevalence and correlates of mental disorders among upper primary school children in grades five through seven in Kenya. The Youth Self Report (YSR) instrument was adapted for use in Kenyan schools and administered to 2267 school children in grades five through seven from 23 randomly selected schools. We estimated the prevalence of DSM-IV mental disorders, and used logistic regression analyses to examine the socio-demographic factors associated with each disorder. The prevalence of any mental disorder among Kenyan school children was 37.7 % (95 % CI = 35.7-39.7 %). Somatic complaints were the most prevalent (29.6 %, 95 % CI = 27.8-31.5 %), followed by affective disorders (14.1 %, 95 % CI = 12.7-15.6 %) and conduct disorder (12.5 %, 95 % CI = 11.2-13.9). The presence of one or more comorbid mental disorder was seen among 18.2 % (95 % CI = 16.6-19.8 %) of children. Male sex, living in a peri-urban vs. rural area, being held back in school, having divorced or separated parents, and having an employed mother were associated with an increased likelihood of having most of the mental disorders examined, whereas increasing age was associated with a reduced likelihood. We observed a high prevalence of mental disorders among school children in Kenya. If not detected early, these disorders may interfere with children's psychological, social, and educational development. Our findings highlight the importance of implementing screening measures in schools that can detect single and multiple disorders in order to improve the mental health and well-being of the next generation.

Radiographic appearance of the normal temporomandibular joint in newborns and small children

Larheim, T.A.

1981-01-01

The radiographic anatomy of the normal temporomandibular joint in newborns and children up to 4 years of age was investigated, partly on specimens, obtained at autopsy, with methods corresponding to clinical procedures, and partly on patients. A rather flat mandibular fossa and immature mandibular head were found at birth, whereas a well-developed articular tubercle and an adult-like radiographic appearance of the joint were found at about one year of age. No evident changes of the radiographic anatomy seemed to occur from one to 4 years of age. A striking similarity was observed between the dystrophic temporomandibular joint in patients with juvenile rheumatoid arthritis and micrognathia and the normal radiographic appearance in the first months of life, indicating an early involvement of this joint in patients developing micrognathia.

Purpose. The objectives of the study were to document the normal CT appearance and size of the crura of the diaphragm in children. Materials and methods. The CT scans of 80 children (0-15 years) were reviewed. The children were divided into eight age groups. The maximal transverse diameters of the right and left crura were measured. They were normalized by comparison with the transverse and anterior-posterior diameters of the 12th thoracic vertebra (T12) and the transverse abdominal diameter at T12. The crura were also evaluated as to whether their contour was smooth or nodular. Results. The diaphragmatic crura of smaller children appear large, relative to body size and the diameters of the T12 vertebral body, compared with those in older children. Crural width does not increase significantly with age. Additionally, the crura were found to have a greater tendency to be nodular in appearance in children under the age of 5 years than in older children. Conclusion. Diaphragmatic crura are more nodular and larger relative to body size in younger children. (orig.). With 6 figs., 2 tabs

In a retrospective study of prelinguistic communication development, clinically referred preschool children (n = 9) aged 3-4 years, who as infants had failed a community-based screening program, were evaluated for features of childhood apraxia of speech (CAS). Four children showed no features and either delayed or normal language, five had from three-to-seven CAS features and all exhibited delayed language. These children were matched by age with 21 children with typically-developing (TD) speech and language skills. Case-control comparisons of retrospective data from 9 months of age for two participants with more severe features of CAS at preschool age showed a dissociated pattern with low expressive quotients on the Receptive-Expressive Emergent Language Assessment-Second Edition (REEL-2) and records of infrequent babbling, but normal receptive quotients. However, other profiles were observed. Two children with milder CAS features showed poor receptive and expressive development similar to other clinically referred children with no CAS features, and one child with severe CAS features showed poor receptive but normal expressive developmental milestones at 9 months and records of frequent babbling. Results suggest some but not all children with features of suspected CAS have a selective deficit originating within speech motor development.

Mooses, M, Haile, DW, Ojiambo, R, Sang, M, Mooses, K, Lane, AR, and Hackney, AC. Shorter ground contact time and better running economy: evidence from female Kenyan runners. J Strength Cond Res XX(X): 000-000, 2018-Previously, it has been concluded that the improvement in running economy (RE) might be considered as a key to the continued improvement in performance when no further increase in V[Combining Dot Above]O2max is observed. To date, RE has been extensively studied among male East African distance runners. By contrast, there is a paucity of data on the RE of female East African runners. A total of 10 female Kenyan runners performed 3 × 1,600-m steady-state run trials on a flat outdoor clay track (400-m lap) at the intensities that corresponded to their everyday training intensities for easy, moderate, and fast running. Running economy together with gait characteristics was determined. Participants showed moderate to very good RE at the first (202 ± 26 ml·kg·km) and second (188 ± 12 ml·kg·km) run trials, respectively. Correlation analysis revealed significant relationship between ground contact time (GCT) and RE at the second run (r = 0.782; p = 0.022), which represented the intensity of anaerobic threshold. This study is the first to report the RE and gait characteristics of East African female athletes measured under everyday training settings. We provided the evidence that GCT is associated with the superior RE of the female Kenyan runners.

This study investigates the influence of oculomotor control, crowding, and attentional factors on visual search in children with normal vision ([NV], n=11), children with visual impairment without nystagmus ([VI-nys], n=11), and children with VI with accompanying nystagmus ([VI+nys], n=26). Exclusion criteria for children with VI were: multiple impairments and visual acuity poorer than 20/400 or better than 20/50. Three search conditions were presented: a row with homogeneous distractors, a matrix with homogeneous distractors, and a matrix with heterogeneous distractors. Element spacing was manipulated in 5 steps from 2 to 32 minutes of arc. Symbols were sized 2 times the threshold acuity to guarantee visibility for the VI groups. During simple row and matrix search with homogeneous distractors children in the VI+nys group were less accurate than children with NV at smaller spacings. Group differences were even more pronounced during matrix search with heterogeneous distractors. Search times were longer in children with VI compared to children with NV. The more extended impairments during serial search reveal greater dependence on oculomotor control during serial compared to parallel search. Copyright © 2014 Elsevier B.V. All rights reserved.

1985-01-01

We attempted to establish a computed tomographic value representing the normal volume ratio of gray matter to white matter (G/W) in children in order to have a baseline for studying various developmental disorders such as white matter hypoplasia. The records of 150 children 16 years of age or younger who had normal cranial computed tomography were reviewed. From these a group of 119 were excluded for various reasons. The remaining 3 were presumed to have normal brains. Using the region of interest function for tracing gray and white matter boundaries, superior and ventral to the foramen of Munro area, measurements were determined for consecutive adjacent frontal slices. Volumes were then calculated for both gray and white matter. A volume ratio of 2.010 (sigma=0.349), G/W, was then derived from each of 31 children. The clinical value of this ratio will be determined by future investigation. (orig.)

Full Text Available Abstract Background Hand hygiene is known to be effective in preventing hospital and community-acquired infections. The increasing number of hand sanitizer brands in Kenyan hospitals and consumer outlets is of concern. Thus the main aim of this study was to evaluate the anti-bacterial efficacy and organoleptic properties of these hand sanitizers in Kenya. Methods This was an experimental, laboratory-based study of 14 different brands of hand sanitizers (coded HS1-14 available in various retail outlets and hospitals in Kenya. Efficacy was evaluated using standard non-pathogenic Escherichia coli (ATCC 25922, Staphylococcus aureus (ATCC 25923 and Pseudomonas aeruginosa (ATCC 27853 as per the European Standard (EN. The logarithmic reduction factors (RF were assessed at baseline and after treatment, and log reduction then calculated. Ten and 25 healthy volunteers participated in the efficacy and organoleptic studies respectively. Results Four (28.6% hand sanitizers (HS12, HS9, HS13 and HS14 showed a 5.9 reduction factor on all the three bacteria strains. Seven (50% hand sanitizers had efficacies of <3 against all the three bacteria strains used. Efficacy on E. Coli was higher compared to the other pathogens. Three hand sanitizers were efficacious on one of the pathogens and not the other. In terms of organoleptic properties, gel-based formulations were rated far higher than the liquid based formulations brands. Conclusion Fifty percent (50% of the selected hand sanitizers in the Kenyan market have efficacy that falls below the World Health Organization (WHO and DIN EN 1500:2013. Of the 14 hand sanitizers found in the Kenyan market, only four showed efficacies that were comparable to the WHO-formulation. There is a need to evaluate how many of these products with <3 efficacy that have been incorporated into the health system for hand hygiene and the country’s policy on regulations on their usage.

Normal nonfluency of children under 5 years old is an important differential diagnosis of primary stuttering. The goals of this research are finding accuracy of diagnoses on children referred to Saba speech therapy Clinic labeled as normal nonfluency and introducing move precise methods of differential diagnosis.  Materials & Methods: The research method is case series study in which through simple sampling procedure stuttering children referring to SabA Clinic during 1382 & 83 were studied. 10. Research tools and data collection consist of: questionnair, spontaneous speech sample recording and determining VOT using laryngograph processor. It should be noted that because normative date of stutteres VOT the lack of the normal subjects VOT are analysed and comared with stutterers. Results: Based on numerical criteria, our findings indicate that only one of stutterers was normal nonfluent and the others were stutteres. VOT data of stutteres also were compared to that of normal matched children. The results revealed that all of stutterers had significantly (P<0.05 longer VOT than normal subjects . Conclusion: This study provides a good numeric and clinical index for speech language pathologists for diagnosis of primary stuttering and normal nonfluency. Morover,. using VOT would help accurate diagnosis.

Nephrotic syndrome (NS) is associated with a significant alteration in protein metabolism. While lowering the concentration of certain proteins, the disease often raises the level of certain other proteins. The current study aimed to investigate the serum erythropoietin (EPO) levels in children with NS either anemic or non-anemic and to compare them to children with iron deficiency anemia (IDA) and healthy controls with normal hemoglobin level (NHB). Sixteen nephrotic children with anemia (NS-A) and 15 nephrotic children with normal hemoglobin level (NS-NHB) were examined and compared with 10 children with iron deficiency anemia (IDA) and 10 healthy controls (NHB). Circulating serum EPO levels, blood indices and iron status were measured in nephrotic patients with anemia (NS-A) and compared to those nephrotic patients with normal HE (NS-NHB). Most NS-A children were steroid resistant. The NS-A children showed greater EPO levels than those without anemia (21.01 ±4.02 mlU/ml versus 9.18 ± 0.79 mlU/ml; P < 0.001) but their response to treatment of anemia was inappropriately low when compared to IDA (EPO 96.9 ±4.9 mlU/ml) despite similar HB concentration. A significant positive correlation was observed between serum EPO and serum albumin in NS-A (r = 0.84, P < 0.001) and in NS-NHB group (r = 0.89, P < 0.001). Moreover, a significant positive correlation was observed between serum EPO and HB in the nephrotic groups indicating a blunted EPO response to anemia in NS-A (r 0.63, P < 0.05) and in NS-NHB group (r = 0.80, P < 0.001). In conclusion, anemia is a common feature of NS and is present even before the worsening of kidney function. Depletion of the iron stores due to loss of iron and transferrin in urine due to massive proteinurea may contribute to the development of anemia, but it was found that iron replacement was ineffective alone

Full Text Available Background and Aim: Sustained attention refers to the ability to maintain attention in target stimuli over a sustained period of time. This study was conducted to develop a Persian version of the sustained auditory attention capacity test and to study its results in normal children.Methods: To develop the Persian version of the sustained auditory attention capacity test, like the original version, speech stimuli were used. The speech stimuli consisted of one hundred monosyllabic words consisting of a 20 times random of and repetition of the words of a 21-word list of monosyllabic words, which were randomly grouped together. The test was carried out at comfortable hearing level using binaural, and diotic presentation modes on 46 normal children of 7 to 11 years of age of both gender.Results: There was a significant difference between age, and an average of impulsiveness error score (p=0.004 and total score of sustained auditory attention capacity test (p=0.005. No significant difference was revealed between age, and an average of inattention error score and attention reduction span index. Gender did not have a significant impact on various indicators of the test.Conclusion: The results of this test on a group of normal hearing children confirmed its ability to measure sustained auditory attention capacity through speech stimuli.

Full Text Available Accurate interpretation of cervical spine imagining can be challenging, especially in children and the elderly. The biomechanics of the developing pediatric spine and age-related degenerative changes predispose these patient populations to injuries centered at the craniocervical junction. In addition, congenital anomalies are common in this region, especially those associated with the axis/dens, due to its complexity in terms of development compared to other vertebral levels. The most common congenital variations of the dens include the os odontoideum and a persistent ossiculum terminale. At times, it is necessary to distinguish normal development, developmental variants, and developmental anomalies from traumatic injuries in the setting of acute traumatic injury. Key imaging features are useful to differentiate between traumatic fractures and normal or variant anatomy acutely; however, the radiologist must first have a basic understanding of the spectrum of normal developmental anatomy and its anatomic variations in order to make an accurate assessment. This review article attempts to provide the basic framework required for accurate interpretation of cervical spine imaging with a focus on the dens, specifically covering the normal development and ossification of the dens, common congenital variants and their various imaging appearances, fracture classifications, imaging appearances, and treatment options.

Full Text Available Objectives: Auditory perception or hearing ability is critical for children in acquisition of language and speech hence hearing loss has different effects on individuals’ linguistic perception, and also on their functions. It seems that deaf people suffer from language and speech impairments such as in perception of complex linguistic constructions. This research was aimed to study the perception of complex syntactic constructions in children with hearing-impairment. Methods: The study design was case-control. According to the inclusion and exclusion criteria, twenty children with severe to profound hearing impairment, aged 8-12 years and twenty normal-hearing children, aged 6-7 years were selected in a simple random sampling from exceptional schools for deaf people and from normal kindergartens and schools for normal cases. The perception of sentences was tested by using a researcher-made task called sentence-picture matching task. At first the content validity was determined and then the reliability was confirmed with Cronbach Alpha Test. Data were analyzed by statistical tests such as Independent Samples T-Test and Mann-Whitney U Test using SPSS. Results: Perception of the group with hearing-impairment was significantly lower than the normal control group. The hearing-impaired children failed to perceive complex syntactic structures. Linguistic function of the group with hearing-impairment on perception of sentences with simple word order was better than on complex sentences. Discussion: If rich linguistic inputs are not available for children during the critical period of the first language acquisition, the syntactic skill, especially in complex syntactic constructions, will not normally develop. In order to establish a foundation for a healthy perfect development of syntax, at the early years of life, children should be exposed to a natural language.

A cohort of extremely prematurely born children and matched term controls was assessed at 5 years of age. The parents completed a questionnaire on their behavioral and social development. The purpose was to illuminate whether the children's general intellectual ability and parental sensitivity were...... associated with behavioral and social development. The index children exhibited more hyperactive behavior and had poorer social skills than the controls. Lower Full Scale IQ (FSIQ) was associated with outward reacting and hyperactive behavior and poorer social skills. Sensitive parenting was associated...... with less outward reacting and less hyperactive behavior. When controlling for differences in FSIQ and parental sensitivity, the index children persisted to have an increased risk of exhibiting hyperactive behavior but not poorer social skills. The index children with normal intellectual development...

The aim of the present study was to compare the benefit of monaural versus binaural ear-level frequency modulated (FM) fitting on speech perception in noise in children with normal hearing. Reception threshold for sentences (RTS) was measured in no-FM, monaural FM, and binaural FM conditions in 22 normally developing children with bilateral normal hearing, aged 8 to 9 years old. Data were gathered using the Pediatric Malay Hearing in Noise Test (P-MyHINT) with speech presented from front and multi-talker babble presented from 90°, 180°, 270° azimuths in a sound treated booth. The results revealed that the use of either monaural or binaural ear level FM receivers provided significantly better mean RTSs than the no-FM condition (Pbinaural FM did not produce a significantly greater benefit in mean RTS than monaural fitting. The benefit of binaural over monaural FM varies across individuals; while binaural fitting provided better RTSs in about 50% of study subjects, there were those in whom binaural fitting resulted in either deterioration or no additional improvement compared to monaural FM fitting. The present study suggests that the use of monaural ear-level FM receivers in children with normal hearing might provide similar benefit as binaural use. Individual subjects' variations of binaural FM benefit over monaural FM suggests that the decision to employ monaural or binaural fitting should be individualized. It should be noted however, that the current study recruits typically developing normal hearing children. Future studies involving normal hearing children with high risk of having difficulty listening in noise is indicated to see if similar findings are obtained.

Congenital disorders of glycosylation (CDG) are caused by defective glycosylation of proteins and lipids. PMM2-CDG is the most common subtype among the CDG. The severity of PMM2-CDG is variable. Patients often have a recognizable phenotype with neurological and multisystem symptoms that might cause early death. We report six patients from three families who are diagnosed with a clinically mild PMM2-CDG and have normal cognitive development. All these patients had delayed gross motor skills with mild-to-moderate neurological findings. Cerebellar hypoplasia was detected in all siblings for whom brain MRI was performed. In 5/6 children the Wechsler Intelligence Scale for Children (WISC) showed normal cognitive development with full scale IQ scores ranging from borderline to average. Four patients were diagnosed with PMM2-CDG at the age of 8 years or later as their neurological symptoms were quite mild and they had been able to participate in regular school programs. We report patients with p.Val231Met/p.Arg239Trp and p.Ile120Thr/p.Gly228Cys genotypes which may cause milder variants of PMM2-CDG. © 2017 Wiley Periodicals, Inc.

Magali Seassau

Full Text Available Studies dealing with developmental aspects of binocular eye movement behaviour during reading are scarce. In this study we have explored binocular strategies during reading and during visual search tasks in a large population of normal young readers. Binocular eye movements were recorded using an infrared video-oculography system in sixty-nine children (aged 6 to 15 and in a group of 10 adults (aged 24 to 39. The main findings are (i in both tasks the number of progressive saccades (to the right and regressive saccades (to the left decreases with age; (ii the amplitude of progressive saccades increases with age in the reading task only; (iii in both tasks, the duration of fixations as well as the total duration of the task decreases with age; (iv in both tasks, the amplitude of disconjugacy recorded during and after the saccades decreases with age; (v children are significantly more accurate in reading than in visual search after 10 years of age. Data reported here confirms and expands previous studies on children's reading. The new finding is that younger children show poorer coordination than adults, both while reading and while performing a visual search task. Both reading skills and binocular saccades coordination improve with age and children reach a similar level to adults after the age of 10. This finding is most likely related to the fact that learning mechanisms responsible for saccade yoking develop during childhood until adolescence.

Full Text Available Background and Aim: Stress is the source of many problems in human-kind lives and threatens people's life constantly. Having hearing-impaired child, not only causes stress in parents, but also affects their marital satisfaction. The purpose of this study was comparing the stress and marital satisfaction status between the normal and hearing-impaired children's parents.Methods: This was a causal-comparative study. Eighty parents of normal children and 80 parents of hearing-impaired children were chosen from rehabilitation centers and kindergartens in city of Tabriz, Iran by available and clustering sampling method. All parents were asked to complete the Friedrich's source of stress and Enrich marital satisfaction questionnaires.Results: Parents of hearing-impaired children endure more stress than the normal hearing ones (p<0.001. The marital satisfaction of hearing-impaired children's parents was lower than the parents of normal hearing children, too (p<0.001.Conclusion: Having a hearing-impaired child causes stress and threatens the levels of marital satisfaction. This requires much more attention and a distinct planning for parents of handicap children to reduce their stress.

Approximately 80% of deaths attributed to malaria worldwide occurred mainly in Africa in 2015. Kenya is one of the major malaria endemic countries, making malaria the leading public health concern in this country. This study intended to document the prevalence of malaria and determine associated factors including socioeconomic status among children aged 6 months to 14 years in Kenya. This study analyzed the secondary data extracted from the 2015 Kenya Malaria Indicator Survey (KMIS), a cross-sectional country representative survey. Associations of demographic, socioeconomic, community-based, and behavioral factors with the prevalence of malaria in children were analyzed using multivariable logistic regression analysis. Data from 7040 children aged 6 months to 14 years were analyzed. The prevalence of malaria showed an upward trend in terms of age, with the highest prevalence among children aged 11-14 years. Prevalence was also higher among rural children (10.16%) compared to urban children (2.93%), as well as poor children (11.05%) compared to rich children (3.23%). The likelihood of having malaria was higher among children aged 10-14 years (AOR = 4.47, 95% CI = 3.33, 6.02; P level of the household head (AOR = 1.15, 95% CI = 1.08, 2.25; P knowledge in practice to control the malaria burden in Kenya. Furthermore, this study suggests that improving the information available through the mass media and introducing behavior change communication and intervention program specifically for those of poor socioeconomic status will help to reduce malaria cases.

To document the prevalence of non-alcoholic fatty liver disease (NAFLD) and metabolic parameters among normal-weight and overweight schoolchildren. Cross-sectional study. Thirteen private schools in urban Faridabad, Haryana. 961 school children aged 5-10 years. Ultrasound testing was done, and 215 with fatty liver on ultrasound underwent further clinical, biochemical and virological testing. Prevalence of fatty liver on ultrasound, and NAFLD and its association with biochemical abnormalities and demographic risk factors. On ultrasound, 215 (22.4%) children had fatty liver; 18.9% in normal-weight and 45.6% in overweight category. Presence and severity of fatty liver disease increased with body mass index (BMI) and age. Among the children with NAFLD, elevated SGOT and SGPT was observed in 21.5% and 10.4% children, respectively. Liver enzyme derangement was significantly higher in overweight children (27% vs 19.4% in normal-weight) and severity of fatty liver (28% vs 20% in mild fatty liver cases). Eleven (8.1%) children with NAFLD had metabolic syndrome. Higher BMI (OR 35.9), severe fatty liver disease (OR 1.7) and female sex (OR 1.9) had strong association with metabolic syndrome. 22.4% of normal-weight and overweight children aged 5-10 years had fatty liver. A high proportion (18.9%) of normal-weight children with fatty liver on ultrasound indicates the silent burden in the population.

BackgroundGiven the usefulness of the product of triglycerides and glucose (TyG) to recognize individuals at high risk for developing cardiovascular events, the aim of this study was to determine whether the TyG index is associated with the presence of cardiovascular risk factors in apparently healthy normal-weight children and adolescents.MethodsApparently healthy children and adolescents with normal weight, aged 6-15 years, were enrolled in a population-based cross-sectional study. The children were allocated into groups with and without cardiovascular risk factors. Cardiovascular risk factors were considered as the occurrence of at least one of the following: elevated blood pressure, hypertriglyceridemia, low high-density lipoprotein cholesterol (HDL-C), or hyperglycemia.ResultsA total of 2,117 children and adolescents were enrolled in the study; of them, 1,078 (50.9%) participants exhibited cardiovascular risk. The adjusted logistic regression analysis showed that elevated TyG index was significantly associated with hypertriglyceridemia (odds ratio (OR)=96.45, 95% confidence interval (CI): 48.44-192.04), low HDL-C (OR=2.07, 95% CI: 1.46-2.92), and hyperglycemia (OR=3.11, 95% CI: 2.05-4.72), but not with elevated blood pressure (OR=1.39, 95% CI: 0.89-2.16).ConclusionThe elevated TyG index is associated with the presence of cardiovascular risk factors in healthy normal-weight children and adolescents.

To compare the optic disc topography parameters of children with juvenile diabetes mellitus and normal children using the Heidelberg Retinal Tomograph (HRT III) (Heidelberg Engineering, Heidelberg, Germany). The topographic optic disc parameters (cup volume, cup area, rim volume, rim area, disc area, mean cup-to-disc ratio, and mean cup depth) of 28 non-glaucomatous eyes of 28 children with type 1 diabetes mellitus and 28 eyes of 28 age-matched healthy children were compared using the nonparametric Mann-Whitney U test. No statistically significant differences were found between cup volume (P = .782), cup area (P = .878), rim volume (P = .853), disc area (P = .452), mean cup-to-disc ratio (P = .852), and mean cup depth (P = .711) of eyes of cases with diabetes mellitus and normal subjects. This result suggests that non-glaucomatous eyes of children with type 1 diabetes mellitus and healthy subjects have similar topographic optic disc characteristics.

Mild traumatic brain injury (mTBI) causes postural control deficits and accordingly comparison of aberrant postural control against normal postural control may help diagnose mTBI. However, in the current literature, little is known regarding the normal pattern of postural control in young children. This study was therefore conducted as an effort to fill this knowledge gap. Eight normal school-aged children participated. Posture assessment was conducted before (7-8 a.m. in the morning) and after (4-7 p.m. in the afternoon) school on regular school days using the Balance Master® evaluation system composed of 3 static tests and 2 dynamic balance tests. A significant difference in the weight-bearing squats was detected between morning hours and afternoon hours (P control of the lateral rhythmic weight shifts was observed at the end of the afternoon than at morning hours (P posture control in humans. On a regular school day, the capacity of postural control and laterality or medio-lateral balance in children varies between morning and afternoon hours. We suggest that posturographic assessment in children, either in normal (e.g., physical education and sports training) or in abnormal conditions (e.g., mTBI-associated balance disorders), be better performed late in the afternoon.

Conclusion The results showed that the children with CP have a lower level of participation in occupations compared to their normally-developing counterparts. One of the reasons for the low participation level of children with CP could be the lack of goal-oriented and occupation-oriented interventions. Thus, this finding will help the healthcare providers to create and develop appropriate  therapeutic and rehabilitation interventions so as to meet the needs of these children and promote their participation level and wellbeing.

In order to assess the range of normal values in radionuclide ventriculography, 53 normal children and adolescents were selected in retrospect. All were exdamined by radionuclide angiocardiography on account of clinical and echocardiographical suspicion of congenital heart disease with a left-to-right shunt; a significant shunt was, however, excluded. In all patients, after equilibration of the radiopharmaceutical the ventricular function was examined by radionuclide ventriculography. The usual volume, time and rate characteristics were evaluated. The normal range was defined as the mean ±2 standard deviations which is 47 to 72% for the ejection fraction of the left ventricle and 31 to 56% for the ejection fraction of the right ventricle.

Running economy (RE) is a determinant of performance in endurance sports and is a complex multi-factorial measure which reflects the combined functioning of bio-mechanical, neuro-muscular, metabolic and cardio-respiratory factors some of which are hereditary or adapt to coaching. Kenyan distance runners have dominated major global events with their unmatched performance for decades and this phenomenon has prompted several investigations aimed at establishing possible factors associated with their performance. This systematic review was aimed at establishing up-to date quantitative synthesis of evidence on biomechanical factors associated with running economy and performance of elite Kenyan distance runners and to provide an algorithm for future research and coaching strategies. A comprehensive electronic search was conducted through June 2017. Quality appraisal was independently done by both reviewers using the STROBE checklist. Descriptive summaries and tables were used to illustrate biomechanical outcomes, mean differences and confidence intervals. Evidence from reviewed studies was graded according to the Australian National Health and Medical Research Council (NHMRC) hierarchy for aetiological factors and meta-analysis was performed where applicable. Eight cross-sectional studies were included. The overall methodological score was moderate (58%). Elite Kenyan distance runners have significant longer gastroc-Achilles tendons compared to their counterparts while their shank length is not significantly longer. There is no certainty of evidence regarding the association between their characteristic unique profile of tall and slender bodies, low BMI and low body mass, short ground contact and flight times, greater forward lean torso and faster and greater forward leg swing with RE and performance. Our findings presents evidence on biomechanical factors associated with RE and performance of elite Kenyan distance runners. Despite these findings, there are a number of

Full Text Available Background and Aim: Reading is the most important human need for learning. In normal-hearing people working memory is a predictor of reading comprehension. In this study the relationship between working memory and reading comprehension skills was studied in hearing-impaired children, and then compared with the normal-hearing group.Methods: This was a descriptive-analytic study. The working memory and reading comprehension skills of 18 (8 male, 10 female sever hearing-impaired children in year five of exceptional schools were compared by means of a reading test with 18 hearing children as control group. The subjects in the control group were of the same gender and educational level of the sample group.Results: The children with hearing loss performed similarly to the normal-hearing children in tasks related to auditory-verbal memory of sounds (reverse, visual-verbal memory of letters, and visual-verbal memory of pictures. However, they showed lower levels of performance in reading comprehension (p<0.001. Moreover, no significant relationship was observed between working memory and reading comprehension skills.Conclusion: Findings indicated that children with hearing loss have a significant impairment in the reading comprehension skill. Impairment in language knowledge and vocabulary may be the main cause of poor reading comprehension in these children. In hearing-impaired children working memory is not a strong predictor of reading comprehension.

We empirically examine the reporting on biotechnology in Kenyan and international newspapers between 2010 and early 2014. We identify news articles that reported on biotechnology and analyze their use of words to determine whether there is a balance in the reporting of perceived risks and benefits. We also consider how the sources used in news articles and how the publication of the Séralini study of rats fed genetically modified maize affect the balance of reporting of perceived risks and benefits. We find that in Kenyan news reporting, more articles mention perceived benefits than risks, but when risks are mentioned, new articles contain more references to risks than to benefits. We also find that sources affect the reporting of perceived risks and benefits and that the Séralini study increased the likelihood that perceived risks are reported in Kenyan news reporting, but not in international newspapers. © The Author(s) 2015.

2005-01-01

Enlarged mesenteric lymph nodes (MLN) are frequently seen in children with abdominal pain and, in the absence of other disorders, have been attributed to primary mesenteric lymphadenitis. To evaluate the prevalence of enlarged MLN (short axis ≥5 mm) as detected by abdominal CT in children with a low likelihood for mesenteric lymphadenopathy. During a 14-month period, we identified all non-contrast abdominal CT examinations performed at a tertiary care pediatric hospital for evaluation of suspected or known renal stones. Two radiologists reviewed the examinations and recognized all enlarged MLN, measured the short-axis diameter, and noted the quadrant location. Sixty-one children were identified who met entry criteria; mean age was 10.7 years (range 1.1-17.3 years). Enlarged MLN were found in 33 (54%) of the 61 children; the largest enlarged MLN was most frequently in the right lower quadrant (RLQ) (29 of 33, 88%). Seventeen of the 61 children (28%) had three or more enlarged MLN; all were in the RLQ. The largest short-axis diameter measured was 10 mm. Summary: MLN with a short-axis diameter of >5-10 mm are commonly found on abdominal CT examination of children with a low likelihood for mesenteric lymphadenopathy and should be considered a non-specific finding. A short-axis diameter of 8 mm might better define the upper limit of normal mesenteric lymph node size in children. (orig.)

Emergence of inter-identity alliances in struggles for transformation of the Kenyan constitution

Jacob Mwathi Mati

2017-03-01

Full Text Available Struggles for transformation of the Kenyan constitution brought into alliances disparate movements from below, sections of middleclass, and factions of political, economic and religious elites, in challenging the government. The emergence of these alliances presents useful cases for examining the dynamic relationship and politics between these movements, and also for probing social movement theory. Specifically, given the centrality of identity consciousness in movements, how were intrinsic class, religious, gender, generational and ethnic identity interests, contestations and cleavages overcome to enable inter-identity alliances in these struggles? More critically, how relevant are the dominant social movement theories in explaining this phenomenon? Is theoretical straightjacketing useful for analysing movements with such diversity? Drawing from in-depth interviews and existing literature on Kenyan constitutional reform struggles, this paper illustrates how alliances between the different identities and movements were forged to allow for a common struggle. The paper further illustrates that while political opportunity structures explain certain aspects of this phenomenon, framing, civic education and community organising strategies were critical enablers for collective identity formation

To define normative standards for the knee in healthy children using contrast-enhanced MRI, focusing on normal synovial membrane thickness. Secondly, presence of joint fluid and bone marrow oedema was evaluated. For this study, children without disorders potentially resulting in (accompanying) arthritis were included. Patients underwent clinical assessments, followed by contrast-enhanced MRI. MRI features were evaluated in consensus using the Juvenile Arthritis MRI Scoring (JAMRIS) system. Additionally, the presence of joint fluid was evaluated. No cartilage lesions or bone abnormalities were observed. We included 57 healthy children. The overall mean thickness of the normal synovial membrane was 0.4 mm (min-max; 0.0-1.8mm). The synovium was thickest around the cruciate ligaments and retropatellar and suprapatellar regions. The mean overall diameter of the largest pocket of joint fluid was 2.8 mm (min-max; 0.9-8.0mm). Bone marrow changes were observed in three children (all in the apex patellae). The normal synovial membrane was maximally 1.8 mm thick, indicating that the JAMRIS cut-off value of 2 mm can be considered a valid measure for evaluating synovial hypertrophy. Some joint fluid and bone marrow changes suggestive of bone marrow oedema in the apex patellae can be seen in healthy children. (orig.)

Full Text Available Abstract Background Cognition in children with anxiety disorders (ANX and comorbid Attention Deficit Disorder (ADHD has received little attention, potentially impacting clinical and academic interventions in this highly disabled group. This study examined several cognitive features relative to children with either pure condition and to normal controls. Methods One hundred and eight children ages 8–12 and parents were diagnosed by semi-structured parent interview and teacher report as having: ANX (any anxiety disorder except OCD or PTSD; n = 52, ADHD (n = 21, or ANX + ADHD (n = 35. All completed measures of academic ability, emotional perception, and working memory. Clinical subjects were compared to 35 normal controls from local schools. Results Groups did not differ significantly on age, gender, or estimated IQ. On analyses of variance, groups differed on academic functioning (Wide Range Achievement Test, p Conclusion Though requiring replication, findings suggest that ANX + ADHD relates to greater cognitive and academic vulnerability than ANX, but may relate to reduced perception of anger.

Johnston, J L; Leong, M S; Checkland, E G; Zuberbuhler, P C; Conger, P R; Quinney, H A

1988-12-01

Body density and skinfold thickness at four sites were measured in 140 normal boys, 168 normal girls, and 6 boys and 7 girls with cystic fibrosis, all aged 8-14 y. Prediction equations for the normal boys and girls for the estimation of body-fat content from skinfold measurements were derived from linear regression of body density vs the log of the sum of the skinfold thickness. The relationship between body density and the log of the sum of the skinfold measurements differed from normal for the boys and girls with cystic fibrosis because of their high body density even though their large residual volume was corrected for. However the sum of skinfold measurements in the children with cystic fibrosis did not differ from normal. Thus body fat percent of these children with cystic fibrosis was underestimated when calculated from body density and invalid when calculated from skinfold thickness.

Low enrollment of women in higher education is a problem in Africa, particularly in Kenya, where despite the government's introduction of affirmative action, female enrollment averages only 36.7% at public universities. This gender gap may be due to the patriarchal influence in Kenyan society, where the role of women is seen as child-bearing,…

Full Text Available Introduction: ADHD is one of the most common disorders among school children throughout the world. Parents of these children are faced with more conflicts than normal children's parents. The Purpose of his study was to evaluate and compare the mental health status of mothers having children with attention deficit / hyperactivity disorder versus mental health of mothers having normal primary school children, Yazd, Iran. Materials and Methods: The sample consisted of 160 mothers of primary-school children who were selected through random cluster sampling; 80 of them had children with attention deficit / hyperactivity disorder and the remaining half had normal children. Also, for the diagnosis of children with attention deficit / hyperactivity disorder, the Conners test as well as test of General Mental Health (GHQ were used to measure mothers' mental health. The data were then analyzed in two levels of descriptive and inferential statistics (T-test and analysis of variance Results: Comparison of mental health and its subscales indicated that mothers of children with ADHD disorder were lower in all aspects of mental health than mothers of normal children. Conclution: According to the research results, mothers of children with attention deficit/hyperactive disorder have lower levels of mental health than mothers of normal children. So, it is recommended that education and health officials provide training courses for these parents to promote their mental health status and consequently their quality of family life.

Lynette Louw

2017-11-01

Full Text Available Orientation: Effective leadership is critical to the survival and growth of organisations. For such leadership to be realised, organisational leaders need to be competent in transformational leadership, which is described as a situation in which the leader and followers empower and shape each other’s behaviour to attain a desired goal. Research purpose: The purpose of this study is to empirically test the relationship between transformational leadership competency and leadership effectiveness in Kenyan indigenous banks. Motivation for this study: In spite of the fact that indigenous banks have been performing better recently, their overall poor performance is cause for concern. This study was motivated by a desire to establish the extent to which the recent improvement is attributable to transformational leadership competency and effectiveness. It is also anticipated that this investigation can highlight aspects of leadership which require more attention in order to sustain improved performance. Research design, approach and method: The study utilised a survey method to collect both quantitative and qualitative data while probability and non-probability techniques were used to sample target population. With 494 respondents targeted in the study, 257 responses were received and analysed. Data analysis was performed using structural equation modelling with Cronbach’s alpha, confirmatory factor analysis and goodness-of-fit indices for analysis and for testing relationships. Main findings: The overall findings confirm that a strong relationship exists between transformational leadership competencies and leadership effectiveness among the leaders of the indigenous banks in Kenya. Practical/managerial implication: Based on the findings of this study, Kenyan indigenous banks are able to identify specific and essential transformational leadership competencies and leadership effectiveness attributes. Contribution: The study has identified that

Normal Hg uptake values in children under 4 years old

1976-01-01

At birth the child's kidney is anatomically and functionally immature and the Hg uptake rate is only a quarter that of an adult. At 12 months this value is already 3/4 that of the adult and the final normal mature values are reached between 3 and 4 years. A curve of normal values for children below 4 years old is proposed, though being based on a small number of measurements only it must be taken as provisional [fr

Schenk-Rootlieb, A J; van Nieuwenhuizen, O; van Zoggel, J; van der Graaf, Y; Willemse, J

1992-09-01

The acuity card procedure proved to be a useful method for assessing visual acuity in children. Normal values of visual acuity measured by this method had already been assessed in children up to four years. To enable application of the test in older children this study obtained values in a group of 396 normal children, aged three months to 13 years. The mean curve as well as the 10th centile was calculated in different age groups. A considerable variation of acuity values causing a 'dip' in the 10th centile was found in the ages 18 to 24 months. A smaller 'dip' was found in the ages 48 to 52 months. This has to be attributed to behavioural properties connected with age. The results obtained in the group of children under four years of age corresponded fairly well with other studies. In schoolchildren a fair agreement could also be found between the data obtained using the acuity card procedure and the data obtained with the Landolt-C rings. Obtaining normal values for the acuity card procedure in children covering a wide age range facilitates recognition of visual handicap in children who are difficult to assess.

Renal function maturation in children: is normalization to surface area valid?

International Nuclear Information System (INIS)

Rutland, M.D.; Hassan, I.M.; Que, L.

1999-01-01

Full text: Gamma camera DTPA renograms were analysed to measure renal function by the rate at which the kidneys took up tracer from the blood. This was expressed either directly as the fractional uptake rate (FUR), which is not related to body size, or it was converted to a camera-based GFR by the formula GFR blood volume x FUR, and this GFR was normalized to a body surface area of 1.73 m2. Most of the patients studied had one completely normal kidney, and one kidney with reflux but normal function and no large scars. The completely normal kidneys contributed, on average, 50% of the total renal function. The results were considered in age bands, to display the effect of age on renal function. The camera-GFR measurements showed the conventional results of poor renal function in early childhood, with a slow rise to near-adult values by the age of 2 years, and somewhat low values throughout childhood. The uptake values showed a different pattern, with renal function rising to adult equivalent values by the age of 4 months, and with children having better renal function than adults throughout most of their childhood. The standard deviations expressed as coefficients of variation (CV) were smaller for the FUR technique than the GFR (Wilcoxon rank test, P < 0.01). These results resemble recent published measurements of absolute DMSA uptake, which are also unrelated to body size and show early renal maturation. The results also suggest that the reason children have lower serum creatinine levels than adults is that they have better renal function. If this were confirmed, it would raise doubts about the usefulness of normalizing renal function to body surface area in children

Luiz Roberto Leite

2001-01-01

Full Text Available Syncope in children is primarily related to vagal hyperreactivity, but ventricular tachycardia (VT way rarely be seen. Catecholaminergic polymorphic VT is a rare entity that can occur in children without heart disease and with a normal QT interval, which may cause syncope and sudden cardiac death. In this report, we describe the clinical features, treatment, and clinical follow-up of three children with syncope associated with physical effort or emotion and cathecolaminergic polymorphic VT. Symptoms were controlled with beta-blockers, but one patient died suddenly in the fourth year of follow-up. Despite the rare occurrence, catecholaminergic polymorphic VT is an important cause of syncope and sudden death in children with no identified heart disease and normal QT interval.

Full Text Available Objective: Sensory systems including proprioceptive, vestibular and visual network play an important role in motor control. Loss of information from each sensory channel can cause body sway on static positions. Materials & Methods: Seventeen blind children (9 girls, 8 boys and 30 deaf children (14 girls, 16 boys participated as the sample groups in Ardabil city. Sixteen normal children (30 girls and 30 boys also selected as the control group. One leg standing and tandem stance tests (reliability=0.87-0.99 in two condition (eyes open and closed was used for static balance evaluation. One-Way ANOVA and LSD post hoc test was used to compare groups, and independent t-test was used for comparing sexes in each group by using SPSS (16 version software. Results: results showed there is no significant difference between blind, deaf and normal girls in any of the balance tasks (p>0.05. While the balance function of deaf and normal boys was better than blind boys in all balance tasks except for tandem stance with eyes closed (p=0.507. Blind girls were better than blind boys in all balance tasks (p=0.05, p=0.02, p=0.02. Deaf boys were better than girls with deafness in one leg stance and tandem stance (eyes open tasks (p=0.04, p=0.02, p=0.04 but there was no significant different between deaf boys and girls in any other tasks (p=0.63, p=0.29, p=0.89. Normal boys have better performance than girls and only in tandem stance (eyes closed (p=0.21 and one leg stance (left foot eyes open (p=0.99 there was no significant difference between normal boys and girls. Conclusion: findings showed that static balance in deaf and normal children were better than the blinds. Since persons with blindness are not able to compensate the visual loss for postural stability, they show decreased postural stability in static conditions.

2005-07-01

A summary of electrical power engineering education in Kenyan universities was presented. Industry expectations for power systems graduates were discussed. Despite rapid changes in electrical power industries around the world, electrical power engineering in Kenya has remained the same for several years. Curriculum changes were last initiated in the 1980s. Universities have not promoted power engineering and its importance to society, and misunderstandings have led to a lack of employment opportunities for graduates and low enrolment levels. Recent advances in artificial neural networks, genetic algorithms, and fuzzy logic within power systems engineering are not currently taught at Kenyan universities. The deregulation of the power industry calls for a re-assessment of how power engineering is taught. Accidents related to poor engineering designs are relatively common in Kenya and have led to the loss of lives. Severe capacity shortfalls experienced in the country have led to a renewed interest in alternative sources of electricity generation. Environmental studies will help students appreciate the importance of using energy sources that do not degrade the environment. It was concluded that the introduction of new approaches to power engineering will result in increased interest from students. The establishment of industry-university collaborations was recommended, as well as active links with international universities. 12 refs.

The aim of this study was to compare working memory span in Persian-speaking preschool children with speech sound disorder (SSD) and their typically speaking peers. Additionally, the study aimed to examine Non-Word Repetition (NWR), Forward Digit Span (FDS) and Backward Digit Span (BDS) in four groups of children with varying severity levels of SSD. The participants in this study comprised 35 children with SSD and 35 typically developing (TD) children -matched for age and sex-as a control group. The participants were between the age range of 48 and 72 months. Two components of working memory including phonological loop and central executive were compared between two groups. We used two tasks (NWR and FDS) to assess phonological loop component, and one task (BDS) to assess central executive component. Percentage of correct consonants (PCC) was used to calculate the severity of SSD. Significant differences were observed between the two groups in all tasks that assess working memory (p working memory between the various severity groups indicated significant differences between different severities of both NWR and FDS tasks among the SSD children (p  0.05). The result showed that PCC scores in TD children were associated with NWR (p  0.05). The working memory skills were weaker in SSD children, in comparison to TD children. In addition, children with varying levels of severity of SSD differed in terms of NWR and FSD, but not BDS. Copyright © 2017 Elsevier B.V. All rights reserved.

Objective: The nutcracker and superior mesenteric artery (SMA) syndromes are rare conditions where the left renal vein or duodenum may be compressed by an unusually acute angle between the SMA and aorta, although the normal angle in children is unknown. We measured the SMA angle to define the normal range in children. Methods: We retrospectively measured SMA angles, left renal vein (LRV) distance, and duodenal distance (DD) in 205 consecutive pediatric abdominal CT. Total and visceral intra-abdominal fat at the level of the umbilicus were also assessed. Results: Mean SMA angle was 45.6 {+-} 19.6 Degree-Sign (range 10.6-112.9 Degree-Sign ), mean LRV distance was 8.6 {+-} 3.9 mm (range 2.0-28.6 mm) and mean DD was 11.3 {+-} 4.8 mm (range 3.6-35.3 mm). There was a significant but weak correlation between %visceral fat volume (%VF) and SMA angle (R = 0.30; p < 0.001), LRV distance (R = 0.37, p < 0.001) and DD (R = 0.32; p < 0.001). Conclusion: There is a wide range of SMA angle, LRV and DD in normal children, which correlated weakly with visceral fat volume. Using a definition of SMA angle <25 Degree-Sign would diagnose 9.3% of asymptomatic children with nutcracker syndrome, and using a DD definition of <8 mm would diagnose 20% with SMA compression. Our findings suggest exercising caution when attributing these rare syndromes to an absolute SMA angle.

2018-04-01

The introduction of neonatal hearing screening and the increasingly early age at which children can receive a cochlear implant has intensified the need for a validated questionnaire to assess the speech production of children aged 0‒18. Such a questionnaire has been created, the LittlEARS ® Early Speech Production Questionnaire (LEESPQ). This study aimed to validate a second, revised edition of the LEESPQ. Questionnaires were returned for 362 children with normal hearing. Completed questionnaires were analysed to determine if the LEESPQ is reliable, prognostically accurate, internally consistent, and if gender or multilingualism affects total scores. Total scores correlated positively with age. The LEESPQ is reliable, accurate, and consistent, and independent of gender or lingual status. A norm curve was created. This second version of the LEESPQ is a valid tool to assess the speech production development of children with normal hearing, aged 0‒18, regardless of their gender. As such, the LEESPQ may be a useful tool to monitor the development of paediatric hearing device users. The second version of the LEESPQ is a valid instrument for assessing early speech production of children aged 0‒18 months.

Diurnal changes in postural control in normal children: Computerized static and dynamic assessments

Directory of Open Access Journals (Sweden)

Sophie Bourelle

2014-07-01

Full Text Available Mild traumatic brain injury (mTBI causes postural control deficits and accordingly comparison of aberrant postural control against normal postural control may help diagnose mTBI. However, in the current literature, little is known regarding the normal pattern of postural control in young children. This study was therefore conducted as an effort to fill this knowledge gap. Eight normal school-aged children participated. Posture assessment was conducted before (7-8 a.m. in the morning and after (4-7 p.m. in the afternoon school on regular school days using the Balance Master ® evaluation system composed of 3 static tests and 2 dynamic balance tests. A significant difference in the weight-bearing squats was detected between morning hours and afternoon hours (P < 0.05. By end of afternoon, the body weight was borne mainly on the left side with the knee fully extended and at various degrees of knee flexion. A significantly better directional control of the lateral rhythmic weight shifts was observed at the end of the afternoon than at morning hours (P < 0.05. In summary, most of our findings are inconsistent with results from previous studies in adults, suggesting age-related differences in posture control in humans. On a regular school day, the capacity of postural control and laterality or medio-lateral balance in children varies between morning and afternoon hours. We suggest that posturographic assessment in children, either in normal (e.g., physical education and sports training or in abnormal conditions (e.g., mTBI-associated balance disorders, be better performed late in the afternoon.

To determine the relationship between mean arterial blood pressure (MAP) and blood viscosity in diabetic type 1 children and healthy controls to investigate whether MAP is independent of blood viscosity in healthy children, and vice versa. Children with diabetes type 1 treated by insulin injection were studied. Controls were healthy children of both sexes. MAP was calculated from systolic and diastolic pressure measurements. Blood viscosity was determined indirectly by measuring blood hemoglobin (Hb) content. The relationship between Hb, hematocrit (Hct) and blood viscosity was determined in a subgroup of controls and diabetics selected at random. 21 (10.6+/-2.5 years) type 1 diabetic children treated with insulin and 25 healthy controls age 9.6+/-1.7 years were studied. Hb was 13.8+/-0.8 g/dl in normal children vs. 14.3+/-0.9 g/dl in the diabetic group (p<0.05). MAP was 71.4+/-8.2 in the normal vs. 82.9+/-7.2 mmHg in the diabetic group (p<0.001). Glucose was 89.3+/-10.6 vs. 202.4+/-87.4 mg/dl respectively. Diabetics had a positive MAP/Hb correlation (p=0.007), while normals showed a non significant (p=0.2) negative correlation. The blood viscosity/Hb relationship was studied in a subgroup of 8 healthy controls and 8 diabetic type 1 children. There was no significant difference in Hb and Hct between groups. Diabetics showed a trend of increasing blood viscosity (+7%, p=0.15). Normal children compensate for the increase in vascular resistance due to increased blood viscosity (increased Hb and Hct) while diabetic children do not, probably due to endothelial dysfunction.

This article will provide information about the Pragmatics Checklist, which consists of 45 items and is scored as: (1) not present, (2) present but preverbal, (3) present with one to three words, and (4) present with complex language. Information for both children who are deaf or hard of hearing and those with normal hearing are presented. Children who are deaf or hard of hearing are significantly older when demonstrating skill with complex language than their normal hearing peers. In general, even at the age of 7 years, there are several items that are not mastered by 75% of the deaf or hard of hearing children. Additionally, the article will provide some suggestions of strategies that can be considered as a means to facilitate the development of these pragmatic language skills for children who are deaf or hard of hearing.

Material girls and Material love: Consuming femininity and the contradictions of post-girl power among Kenyan schoolgirls

Science.gov (United States)

Mojola, Sanyu A.

2016-01-01

In this paper, I use qualitative data to explore the practices engaged in by Kenyan schoolgirls to participate in modern consuming womanhood, as well as the contradictory implications of these practices for thinking about globalized mediated femininities and their enactment in resource-poor settings. The paper examines the centrality of consumption to valued modern femininity among young women around the world, as well as the structural reality of gendered access to income. I show how the cooptation of the materiality of romantic love and normative expectations of male provision in romantic relationships bridge the gap between consumption desires and economic realities among Kenyan schoolgirls in both powerful and problematic ways. The paper ends with a reflection of the implications of these findings for post-girl power, the post-feminist age and the re-inscription of patriarchy. PMID:28344428

Full Text Available Objective　To calculate the radios of peak area of proton magnetic resonance spectroscopy metabolites in brain white matter of normal infants and young children, to observe the features of metabolite spectra, and to explore the relations between their ratio with age. Methods　The peak areas of metabolites, including N-acetyl aspartate (NAA, choline (Cho, creatine (Cr, and their ratio of NAA/Cho, NAA/Cr, Cho/Cr, in paraventricular white matter of 180 normal infants and young children with different ages as evaluated by multi-voxel proton magnetic resonance spectroscopy. Results　In paraventricular white matter, spectrum of NAA increased, and that of Cho decreased gradually, while both of them were stabilized at 2 years old. Cr was increased obviously within 3 months, and stabilized after 4 months. Significant differences were found in ratio of different metabolites in paraventricular white matter in different ages (P<0.05. The ratios of NAA/Cho and NAA/Cr in paraventricular white mater were positively correlated with age (r=0.741, r=0.625, while that of Cho/Cr was negatively correlated with age (r=–0.552, P<0.05. Conclusion　The ratios of different metabolites are different in brain white matter in infants of different ages. Metabolites concentrations in brain white matter are correlated to some extent with age, which may provide a diagnostic criterion for evaluation of normal brain development and abnormal brain metabolism.

Less than 10% of implantees were postlingually deaf adults. The vast majority, i.e. 90% were pre- and perilingually profoundly deaf children. The aim of this study was to assess the influence of improved auditory perception due to cochlear implantation on comprehension of abstract words in children as compared with hearing impaired children with conventional hearing aids and normal hearing children. Methods. Thirty children were enrolled in this study: 20 hearing impaired and 10 normal hearing. The vocabulary test was used. Results. The overall results for the whole test (100 words showed a significant difference in favor of the normal hearing as compared with hearing impaired children. The normal hearing children successfully described or defined 77.93% of a total of 100 words. Success rate for the cochlear implanted children was 26.87% and for the hearing impaired children with conventional hearing aids 20.32%. Conclusion. Testing for abstract words showed a statistically significant difference between the cochlear implanted and the hearing impaired children with hearing aids (Mann- Whitney U-test, p = 0.019 implying considerable advantage of cochlear implants over hearing aids regarding successful speech development in prelingually deaf children.

Heel pain in children and secondary MR imaging (MRI) of the hindfoot have been increasing in incidence. Our purpose is to illustrate the, previously unreported, MRI stages in development of the posterior calcaneal apophysis, with attention to imaging pitfalls. This should aid in distinguishing normal growth from true disease. Consecutive ankle MRIs in children <18 years, from 2008-2014, were subdivided into 0≤5, 5≤10, 10≤15 and 15≤18 age groups and retrospectively reviewed for development of the calcaneal apophysis. 204 ankle MRI studies in 188 children were identified. 40 studies were excluded with final cohort of 164 studies in 154 patients (82 boys, 72 girls). The calcaneal apophysis was cartilaginous until age 5. Foci of decreased as well as increased signal were embedded in cartilage, prior to ossification. Early, secondary ossification centers appeared in plantar third of the apophysis in 100 % of children by age 7. Increased T2 signal in the ossifications was seen in 30 % of children. Apohyseal fusion began at 12 and was complete in 78 % of 14≤15 year olds and in 88 % of 15≤18 year olds. Curvilinear low signal in the ossification centers, paralleling, but distinguished from growth plate, and not be confused with fracture line, was common. Development of the posterior calcaneus follows a unique sequence. Apophyseal fusion occurs earlier than reported in the literature. Familiarity with this maturation pattern, in particular the apophyseal increased T2 signal and the linear low signal paralleling the growth plate, will avoid misinterpreting it for pathology.

Previous magnetic resonance imaging (MRI)-based volumetric studies have shown age-related increases in the volume of total white matter and decreases in the volume of total gray matter of normal children. Recent adaptations of image analysis strategies enable the detection of human brain growth with improved spatial resolution. In this article, we further explore the spatio-temporal complexity of adolescent brain maturation with tensor-based morphometry. By utilizing a novel non-linear elastic intensity-based registration algorithm on the serial structural MRI scans of 13 healthy children, individual Jacobian growth maps are generated and then registered to a common anatomical space. Statistical analyses reveal significant tissue growth in cerebral white matter, contrasted with gray matter loss in parietal, temporal, and occipital lobe. In addition, a linear regression with age and gender suggests a slowing down of the growth rate in regions with the greatest white matter growth. We demonstrate that a tensor-based Jacobian map is a sensitive and reliable method to detect regional tissue changes during development. (c) 2007 Wiley-Liss, Inc.

Background. Peripheral neuropathy (PN) is common among patients receiving antiretroviral therapy (ART) in resource-limited settings. We report the incidence of and risk factors for PN among human immunodeficiency virus (HIV)–infected Kenyan adults initiating ART. Methods. An inception cohort was formed of adults initiating ART. They were screened for PN at baseline and every 3 months for 1 year. We used the validated Brief Peripheral Neuropathy Screen (BPNS) that includes symptoms and signs (vibration perception and ankle reflexes) of PN. Results. Twenty-two (11%) of 199 patients had PN at baseline screening. One hundred fifty patients without evidence of PN at baseline were followed for a median of 366 days (interquartile range, 351–399). The incidence of PN was 11.9 per 100 person-years (95% confidence interval [CI], 6.9–19.1) and was higher in women than men (17.7 vs 1.9 per 100 person-years; rate ratio, 9.6; 95% CI, 1.27–72, P = .03). In stratified analyses, female sex remained statistically significant after adjustment for each of the following variables: age, CD4 cell count, body mass index, ART regimen, and tuberculosis treatment. Stratifying hemoglobin levels decreased the hazard ratio from 9.6 to 7.40 (P = .05), with higher levels corresponding to a lower risk of PN. Conclusions. HIV-infected Kenyan women were almost 10 times more likely than men to develop PN in the first year of ART. The risk decreased slightly at higher hemoglobin levels. Preventing or treating anemia in women before ART initiation and implementing BPNS during the first year of ART, the period of highest risk, could ameliorate the risk of PN. PMID:21844033

Prior to interpreting PET/CT, it is crucial to understand the normal biodistribution of fluorodeoxyglucose (FDG). It is also important to realize that the normal biodistribution can vary between adults and children. Although many studies have defined normal patterns of pediatric FDG uptake in structures like the thymus, brown fat and bone marrow, patterns of normal pediatric bowel activity, specifically uptake within the appendix, have not been well described. Active lymphoid tissue has increased FDG uptake when compared with inactive tissue. Since children have more active lymphoid tissue than adults, and because the appendix contains aggregated lymphoid tissue, we postulated that appendiceal uptake may be increased in pediatric patients. To define the normal level of appendiceal FDG activity in children by evaluating a series of consecutive FDG PET/CT scans performed for other indications. After obtaining IRB approval, we retrospectively reviewed 128 consecutive whole-body pediatric FDG PET/CT examinations obtained for a variety of clinical indications. CT scans on which the appendix could not be visualized were excluded from analysis. CT scans on which the appendix could be visualized were evaluated for underlying appendiceal pathology. Studies with appendiceal or periappendiceal pathology by CT criteria were excluded. A region of interest (ROI) was placed over a portion of each appendix and appendiceal maximum standardized uptake value (SUVmax) was calculated. If an adjacent loop of bowel activity interfered with accurate measurements of the appendix SUVmax, the scan was excluded from the analysis. A chart review was performed on patients with elevated appendiceal SUVmax values to ensure that the patients did not have clinical symptomatology suggestive of acute appendicitis. When the appendix or a portion of the appendix could be visualized and accurately measured, the SUVmax was determined. SUVmax of the appendix was compared to the SUVmax of normal liver and

To evaluate growth and development in children with anorectal malformations and to analyze effects of type of malformation and comorbidities. Non-syndromal children with anorectal malformations were prospectively evaluated at 0.5, 1, 2, and 5 years. Biometrics were obtained at all visits. Mental and psychomotor function development was determined. 108 children (59% male) were included. 49% had a high malformation, and 46% had ≥ 1 additional major comorbidity. All growth parameters were below the norm at all ages (pChildren with ≥ 1 additional major anomaly had lower height at all ages; at 5 years, mean (95% CI) height was -1.83 (-2.7 to -1.1) and -0.70 (-1.3 to -0.1) in children with and without comorbidities, respectively (p=0.019). Mental development was normal, irrespective of the type of malformation or comorbidities. Motor development was delayed at all ages. At 5 years, motor development (n=30) was normal in 70%, borderline in 23%, and 7% had definitive motor problems (p=0.043). Non-syndromal children with anorectal malformations are at risk for growth impairment, especially those with additional major comorbidity. Mental development is normal. Motor development is slightly impaired. Supportive care should focus on growth, dietary management, and motor development besides defecation problems. Copyright © 2013 Elsevier Inc.

Full Text Available Objective: This study was conducted aimed to compare the growth indices in 2 years old children with a history of low birth weight with normal birth weight children.Methods: Current retrospective cohort study on all two-year children with low birth weight and three times the normal weight children covered by health centers of Kahnooj, was conducted in 2015. Cares at birth, 1, 2, 4, 6, 7, 9, 12, 15, 18 and 24 months of age were studied and, child growth indices (weight, height, head circumference, along with some demographic variables were studied. Information were entered SPSS version 20 and the analysis was performed.Results: There were significant differences in children's growth of both groups in all periods of care. Despite the same slope, growth pattern in children showed a significant difference. Young mother, girl sex of baby and preterm birth are predictor factors of low birth weight.Conclusion: Trends and growth patterns of weight, height and head circumference in underweight children have significant difference with normal children and, despite the same slope, these children can not compensate for the backwardness of its growth to the age of two. So you need to plot separate growth curves for these children and, possible preventive measures should be taken to prevent bearing underweight baby.

Xueqing Chen

Full Text Available The aim of this study is to survey and compare the development of auditory skills in young children with Mondini dysplasia and profoundly-deaf young children with radiologically normal inner ears over a period of 3 years after cochlear implantation. A total of 545 young children (age 7 to 36 months with prelingual, severe to profound hearing loss participated in this study. All children received cochlear implantation. Based on whether or not there was a Mondini dysplasia as diagnosed with CT scanning, the subjects were divided into 2 groups: (A 514 young children with radiologically normal inner ears and (B 31 young children with Mondini dysplasia. The Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS was used to assess the children's auditory skills that include vocalization changes, spontaneous alerting to sounds in everyday living environments, and the ability to derive meaning from sounds. The assessment was performed prior to surgery and at 1, 3, 6, 9, 12, 24, and 36 months after implant device switch-on. The mean scores for overall auditory skills were not significantly different between groups A and B at pre-surgery, 1, 12, 24, and 36 months post-surgery, but were significantly different at 3, 6, and 9 months post-surgery. The mean scores for all auditory skills in children with Mondini dysplasia showed significant improvement over time. The mean scores for the three subcategories of auditory skills in children with Mondini dysplasia also showed significant differences at pre-surgery, 1, 3, 6, and 9 months, however, there were no significant differences at 12, 24, and 36 months. Overall, the auditory skills of young children with Mondini dysplasia developed rapidly after cochlear implantation, in a similar manner to that of young children with radiologically normal inner ears. Cochlear implantation is an effective intervention for young children with Mondini dysplasia.

2013-01-01

Women living on rural Kenyan dairy farms spend significant amounts of time collecting wood for cooking. Biogas digesters, which generate biogas for cooking from the anaerobic decomposition of livestock manure, are an alternative fuel source. The objective of this study was to quantify the quality of life and health benefits of installing biogas digesters on rural Kenyan dairy farms with respect to wood utilisation. Women from 62 farms (31 biogas farms and 31 referent farms) participated in interviews to determine reliance on wood and the impact of biogas digesters on this reliance. Self-reported back pain, time spent collecting wood and money spent on wood were significantly lower (p biogas group, compared to referent farms. Multivariable linear regression showed that wood consumption increased by 2 lbs/day for each additional family member living on a farm. For an average family of three people, the addition of one cow was associated with increased wood consumption by 1.0 lb/day on biogas farms but by 4.4 lbs/day on referent farms (significant interaction variable - likely due to additional hot water for cleaning milk collection equipment). Biogas digesters represent a potentially important technology that can reduce reliance on wood fuel and improve health for Kenyan dairy farmers.

Peck, Blake; Lillibridge, Jennifer

2005-03-01

This article reports findings from a larger qualitative study conducted to gain insight into the experience of fathers living with their chronically-ill children in rural Victoria, Australia. Data were collected via unstructured interviews with four fathers. The findings presented in this article explore the phenomena of normalization for fathers within the chronic illness experience. Fathers described normalizing the experience of living with their chronically-ill child as involving a combination of various coping strategies and behaviours including: (1) accepting the child's condition, (2) changing expectations, (3) focusing energies on a day-to-day basis, (4) minimizing knowledge-seeking behaviours, and (5) engaging in external distraction activities. Findings highlight the complex and unique normalization strategies these men utilized and contribute to knowledge and understanding of the complex nature of raising a chronically-ill child in rural Australia and provide a sound basis upon which to guide an ongoing and holistic assessment of fathers with chronically-ill children.

This study aimed to determine the association between sleep habits (including bedtime, wake up time, sleep duration, and sleep disorder score) and physical characteristics, physical activity level, and food pattern in overweight and obese versus normal weight children. Case control study. 164 Malaysian boys and girls aged 6-€“12 years. Anthropometric measurements included weight, height, waist circumference, and body fat percentage. Subjects divided into normal weight (n = 82) and overweight/obese (n = 82) group based on World Health Organization 2007 BMI-for-age criteria and were matched one by one based on ethnicity, gender, and age plus minus one year. Questionnaires related to sleep habits, physical activity, and food frequency were proxy-reported by parents. Sleep disorder score was measured by Children Sleep Habit Questionnaire. Sleep disorder score and carbohydrate intake (%) to total energy intake were significantly higher in overweight/obese group (p < 0.01 and p < 0.05, respectively). After adjusting for age and gender, sleep disorder score was correlated with BMI (r = 0.275, p < 0.001), weight (r = 0.253, p < 0.001), and WC (r = 0.293, p < 0.001). Based on adjusted odd ratio, children with shortest sleep duration were found to have 4.5 times higher odds of being overweight/obese (odd ratio: 4.536, 95% CI: 1.912-€“8.898) compared to children with normal sleep duration. The odds of being overweight/obese in children with sleep disorder score higher than 48 were 2.17 times more than children with sleep disorder score less than 48. Children who sleep lees than normal amount, had poor sleep quality, and consumed more carbohydrates were at higher risk of overweight/obesity. © 2014 Asian Oceanian Association for the Study of Obesity .

Early caregiving can have an impact on brain structure and function in children. The influence of extreme caregiving experiences has been demonstrated, but studies on the influence of normal variation in parenting quality are scarce. Moreover, no studies to date have included the role of both maternal and paternal sensitivity in child brain maturation. This study examined the prospective relation between mothers' and fathers' sensitive caregiving in early childhood and brain structure later in childhood. Participants were enrolled in a population-based prenatal cohort. For 191 families, maternal and paternal sensitivity was repeatedly observed when the child was between 1 year and 4 years of age. Head circumference was assessed at 6 weeks, and brain structure was assessed using magnetic resonance imaging (MRI) measurements at 8 years of age. Higher levels of parental sensitivity in early childhood were associated with larger total brain volume (adjusted β = 0.15, p = .01) and gray matter volume (adjusted β = 0.16, p = .01) at 8 years, controlling for infant head size. Higher levels of maternal sensitivity in early childhood were associated with a larger gray matter volume (adjusted β = 0.13, p = .04) at 8 years, independent of infant head circumference. Associations with maternal versus paternal sensitivity were not significantly different. Normal variation in caregiving quality is related to markers of more optimal brain development in children. The results illustrate the important role of both mothers and fathers in child brain development. Copyright © 2015 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

Full Text Available Background and Aim : Theory of mind refers to the ability to understand the others have mental states that can be different from one's own mental states or facts. This study aimed to investigate the relationship of theory of mind and executive functions in normal hearing, deaf, and cochlear-implanted children.Methods: The study population consisted of normal, deaf and cochlear-implanted girl students in Mashhad city, Iran. Using random sampling, 30 children (10 normal, 10 deaf and 10 cochlear-implanted in age groups of 8-12 years old were selected. To measure the theoty of mind, theory of mind 38-item scale and to assess executive function, Coolidge neuropsychological and personality test was used. Research data were analyzed using the Spearman correlation coefficient, analysis of variance and Kruskal-Wallis tests.Results: There was a significant difference between the groups in the theory of mind and executive function subscales, organization, planning-decision-making, and inhibition. Between normal and deaf groups (p=0.01, as well as cochlear-implanted and deaf groups (p=0.01, there was significant difference in planning decision-making subscale. There was not any significant relationship between the theory of mind and executive functions generally or the theory of mind and executive function subscales in these three groups independently.Conclusion: Based on our findings, cochlear-implanted and deaf children have lower performance in theory of mind and executive function compared with normal hearing children.

To investigate the status of pubertal development in children born with assisted reproductive technology (ART). A retrospective analysis was performed on the pubertal development data of children born with ART in Peking University Third Hospital from 1994 to 2003 (ART group). The data in the cross-sectional study "Reports on the Physical Fitness and Health Research of Chinese School Students in 2010" were used as a control. The age at menarche and the age at spermarche were compared between the two groups. The status of pubertal development in the overweight and obese children in the ART group was evaluated to investigate the correlation between pubertal development and body mass index (BMI). A total of 200 children born with ART were enrolled in this study, and 72 of them (41 males and 31 females) completed the survey (response rate=36.0%). In the ART group, the mean age at spermarche and the mean age at menarche were 13.9 years (95%CI: 13.7-14.3 years) and 12.2 years (95%CI: 11.8-12.6 years), respectively. There were no significant differences in the age at spermarche and the age at menarche between the ART and control groups (P>0.05). In the ART group, there were no significant differences in the age at spermarche and the age at menarche between the overweight and obese children and the normal weight children (P>0.05). There were also no significant differences in overweight rate and obesity rate between the children in the ART group and the adolescents in Beijing (P>0.05). In the ART group, there was no significant correlation between the age at spermarche or menarche and BMI (P>0.05). No delayed or precocious puberty is observed in children born with ART. This is consistent with the normal control data. And there is no significant correlation between pubertal development and BMI in children born with ART.

Full Text Available This article scaffolds on customer relationship management (CRM theory and explores the association between electronic CRM (e-CRM and electronic customer’s (e-customer electronic loyalty (e-loyalty in the banking sector. By using a survey design, data was collected from a convenience sample of customers of a major Kenyan commercial bank, and analysed using structural equation and multiple regression modelling. The findings reveal that there is a positive relationship between e-CRM and e-customers’ loyalty. The e-CRM features at all three stages of an electronic transaction cycle namely, pre-service, during-service and after-service, significantly influence the e-customers’ loyalty in the banking sector. Thus, to capitalize on the range of benefits that emanate from the use of e-CRM, continued review and enhancement of marketing strategies is needed, so as to achieve e-customers’ loyalty particularly, at the post-service stage. Kenyan commercial bank managers should focus on customer satisfaction specifically at post-service stage, to increase their ecustomers’ loyalty.

After a seizure, individuals with epilepsy have reported diverse symptoms in the postictal period, especially motor and cognitive dysfunction. However, these phenomena have not been well characterized in children, and their impact on patient well-being is not understood. We hypothesized that in a subset of epilepsy patients, postictal symptoms would affect their ability to return to normal childhood activities. To test our hypothesis, a survey-based approach was used to characterize the type, frequency, and duration, as well as the impact of these symptoms on the ability of these children to return to their normal activities. In this prospective study, data were analyzed from 208 patients seen in the pediatric neurology outpatient clinic at the Alberta Children's Hospital. We found that 86% (179 out of 208) of respondents reported postictal symptoms, with the most common symptom category being fatigue, sleepiness, and/or tiredness (90%; 161 of 179). The greatest impact resulted from weakness or being unable to move normally, which prevented 78% of those affected (71 of 91) from returning to normal activities after a seizure. Children who had focal seizures were more likely to experience postictal fatigue, sleepiness, or tiredness (P = 0.01; Bonferroni corrected), but no other postictal symptoms were significantly associated with a specific seizure type or epilepsy syndrome. The results of this study further our understanding of the frequency, type, and duration of symptoms experienced in the postictal period and how these symptoms impact children with epilepsy. It is clear that postictal phenomena often occur after epileptic seizures and have a significant impact on the lives of children with epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Background. The aim of the study was to find whether children conceived through ICSI and their families differ from the children conceived in normally fertile families. Methods. The study group (SG consisted of 41 children aged 3 years conceived through ICSI: 22 boys, 19 girls, 6 pairs of twins, and the control group (CG of 41 children matched for sex, age and twin pairs. Family characteristics were assessed using a self-administered questionnaire on family characteristics, conception, pregnancy, labour and delivery, and postpartum period. The children’s development was assessed using the Developmental Čuturić Scale, and the parents filled in the questionnaire from SPP-3 on signs of inadequate child’s adaptation. The mother’s personality was assessed using the BFQ. Differences between the groups were analyzed using SPSS for Windows. Results. Comparison between the SG and CG showed the following statistically significant differences: in the SG mothers were older, the ICSI child was more frequently the only child, the mean duration of infertility treatment was 4 years, in most couples pregnancy occurred by the 3rd ICSI attempt, the family had a better socio-economic status. During the pregnancy, the SG mothers were less ambivalent towards pregnancy and the relationship between the partners improved, after delivery their psychic condition deteriorated, they were more concerned whether their child would develop normally. In the SG parents’ opinion, the quality of life improved after their baby’s birth; they described their children as more demanding and more restless. More ICSI children were cared after by their grand parents than their CG peers that mostly attended kindergarten. The development of all children was normal. Although the sum of signs of inadequate adaptation was comparable between the groups, the ICSI children demonstrated stronger intensity of individual sings. Factor analysis showed very heterogenic latent structure

``I Have Been Given the Power to Teach. The Children Understand Me Very Well.'' The Social and Academic Impact of Deaf Teacher Training in Kenya

Science.gov (United States)

Johnstone, Christopher; Corce, Heidi

2010-02-01

Kenya has 41 Deaf schools that serve children from Class 1 through secondary school. These schools are all characterised by the fact that they have very few teachers who are fluent in Kenyan sign language. In order to meet the needs of schools and to provide employment opportunities for Deaf Kenyan adults, a small non-governmental organisation identified Deaf secondary school students for training. They received two years of teacher training free of charge. Most have since been awarded teaching contracts by the Kenyan Teacher Service Commission or local school boards. This article reports on results from a preliminary study of the social and academic impacts of this innovation. Results indicate that Deaf teachers are inspirational in the classroom, represent a significant resource for their school communities and are preferred by Deaf students. A follow-up study on the relative learning gains of Deaf students when taught by Deaf teachers is planned once relevant data are available.

Attention deficit hyperactivity disorder (ADHD) is the most common behavioral problem during childhood and in school-aged children. Various projection drawings have been designed for assessing children's personality and psychological disorders including the tests of draw a person (DAP) and draw a family (DAF). We aimed to compare the differences between typically developing children and children with ADHD using these tests. In this case-control study, all the 9-10 year-old boy students studying at the third and fourth grades were enrolled from schools in the 2nd educational district of Shiraz, south of Iran. Eighty students were then selected and enrolled into the ADHD group and the control group. The Diagnostic and Statistical Manual of Mental Disorders, 4th edition- text Revised (DSM-IV-TR), and the Child Symptoms Inventory were used to diagnose the children with ADHD. We evaluated and analyzed impulsiveness, non-impulsiveness, emotional problems and incompatibility indices in the DAP and DAF tests in each group. A significant difference was found in the indices of incompatibility and emotional problems, impulsiveness, non-impulsiveness and DAF between typically developing children and those with ADHD. The mean (±SD) total scores of the above mentioned indices in the ADHD group were 19.79(±2.94), 12.31(±1.84), 5.26(±2.29) and 5.89(±2.13), respectively (Pchildren with ADHD using these two drawing tests. The rate of impulsivity and emotional problems indices in drawings of children with ADHD was markedly more common than those of the typically developing children. This suggests the need for further assessment to screen ADHD.

Full Text Available Background and Aim: Families who have a child with hearing deficiency deal with different challenges, and mothers have a greater responsibility towards these children because of their traditional role of caregiver; so, they deal with more psychological problems. The aim of this study was to compare the psychological well-being and coping styles in mothers of deaf and normal children.Methods: In this cross-sectional and post event study (causal-comparative method, 30 mothers of deaf students and 30 mothers of normal students from elementary schools of Ardabil, Iran, were selected using available sampling. The Ryff psychological well-being (1989 and Billings and Moos coping styles (1981 questionnaires were used in this study. The data were analyzed using MANOVA test.Results: We found that in mother's of deaf children, psychological well-being and its components was significantly lower than mothers of normal children (p<0.01 and p<0.05, respectively. There was a significant difference between two groups in terms of cognitive coping style, too (p<0.01. However, mothers of deaf children used less cognitive coping style.Conclusions: It seems that child's hearing loss affects on mothers psychological well-being and coping styles; this effect can be visible as psychological problems and lower use of adaptive coping styles.

Fasting glucose (hexoquinase) and insulin blood levels (chemiluminiscence), were determined and HOMA index was calculated. Percentile distributions of these variables were calculated. The reference group included only subjects with normal body mass index and fasting blood glucose (n = 1,192). Girls had higher insulin and HOMA values than boys (12.5 ± 6.0 and 9.1 ± 4.9 μϋ/mL (p HOMA mean values than subjects with Tanner III and IV (9.0 ± 4.3 and 12.5 ± 6.2μϋ/ml (p HOMA distributions according to sex and maturation, was selected as the upper cut-off point to identify individuals with insulin resistance. HOMA cutoff point for Tanner I and II boys was 3.2, for Tanner I and II girls was 4.1, for Tanner III and IV boys was 4.2 and for Tanner III and IV girls was 5.0.

Fragmentary ossification of the inferior patella is often dismissed as a normal variant in children younger than 10 years of age. The purpose of this study was to determine whether fragmentary inferior patellar pole ossification is a normal variant or is associated with symptoms or signs of pathology using MRI and clinical exam findings as reference. A retrospective review was performed on 150 patients ages 5-10 years who underwent 164 knee radiography and MRI exams (45.1% male, mean age: 7.8 years). The presence or absence of inferior patellar pole fragmentation on radiography was correlated with the presence or absence of edema-like signal on MR images. Clinical notes were reviewed for the presence of symptoms or signs referable to the inferior patellar pole. These data were compared with a 1:1 age- and sex-matched control group without inferior pole fragmentation. Statistical analysis was performed using two-tailed t-tests. Forty of 164 (24.4%) knee radiographs showed fragmentary ossification of the inferior patella. Of these 40 knees, 62.5% (25/40) had edema-like signal of the inferior patellar bone marrow compared with 7.5% (3/40) of controls (P = 0.035). Patients with fragmentary ossification at the inferior patella had a significantly higher incidence of documented focal inferior patellar pain compared with controls (20% vs. 2.5%, P = 0.015). Inferior patellar pole fragmentation in children 5 to 10 years of age may be associated with localized symptoms and bone marrow edema-like signal and should not be routinely dismissed as a normal variant of ossification.

Studies conducted in developing countries have noted associations between concurrent stunting, social-emotional problems and poor cognitive ability in young children. However, the relative contribution of these variables in Latin America is likely changing as undernutrition rates decline and prevalence of childhood obesity rises. We conducted a cross-sectional study of 106 normal-weight and 109 obese preschool children to compare the relative contribution of early nutrition, sociodemographic factors and psychosocial variables on cognitive development in normal-weight and obese preschool children in Chile. The study variables were categorized as: (1) socio-demographic (age, sex, birth order and socioeconomic) (2) early nutrition (maternal height, birth weight, birth length and height at 5 years) (3) psychosocial factors (maternal depression, social-emotional wellbeing and home space sufficiency). In order to assess determinants of cognitive development at 4-5 years we measured intelligence quotient (IQ); variability in normal children was mostly explained by socio-demographic characteristics (r(2) = 0.26), while in obese children early nutritional factors had a significant effect (r(2) = 0.12) beyond socio-demographic factors (r(2) = 0.19). Normal-weight children, who were first born, of slightly better SES and height Z score >1, had an IQ ≥ 6 points greater than their counterparts (p birth weight >4,000 g and low risk of socio-emotional problems had on average ≥5 IQ points greater than their peers (p < 0.05). We conclude that in Chile, a post-transitional country, IQ variability of normal children was mostly explained by socio-demographic characteristics; while in obese children, early nutrition also played a significant role.

Full Text Available Objective: Theory of mind (ToM or mindreading is an aspect of social cognition that evaluates mental states and beliefs of oneself and others. Validity and reliability are very important criteria when evaluating standard tests; and without them, these tests are not usable. The aim of this study was to systematically review the validity and reliability of published English comprehensive ToM tests developed for normal preschool children.Method: We searched MEDLINE (PubMed interface, Web of Science, Science direct, PsycINFO, and also evidence base Medicine (The Cochrane Library databases from 1990 to June 2015. Search strategy was Latin transcription of ‘Theory of Mind’ AND test AND children. Also, we manually studied the reference lists of all final searched articles and carried out a search of their references. Inclusion criteria were as follows: Valid and reliable diagnostic ToM tests published from 1990 to June 2015 for normal preschool children; and exclusion criteria were as follows: the studies that only used ToM tests and single tasks (false belief tasks for ToM assessment and/or had no description about structure, validity or reliability of their tests. Methodological quality of the selected articles was assessed using the Critical Appraisal Skills Programme (CASP.Result: In primary searching, we found 1237 articles in total databases. After removing duplicates and applying all inclusion and exclusion criteria, we selected 11 tests for this systematic review. Conclusion: There were a few valid, reliable and comprehensive ToM tests for normal preschool children. However, we had limitations concerning the included articles. The defined ToM tests were different in populations, tasks, mode of presentations, scoring, mode of responses, times and other variables. Also, they had various validities and reliabilities. Therefore, it is recommended that the researchers and clinicians select the ToM tests according to their psychometric

Recommended disease prevention behaviors of hand washing, hygienic hand drying, and covering one's mouth and nose in a hygienic manner when coughing and sneezing appear to be simple behaviors but continue to be a challenge to successfully promote and sustain worldwide. We conducted a qualitative inquiry to better understand current hand drying behaviors associated with activities of daily living, and mouth and nose covering practices, among Kenyans. We conducted 7 focus group discussions; 30 in-depth interviews; 10 structured household observations; and 75 structured observations in public venues in the urban area of Kisumu; rural communities surrounding Kisumu; and a peri-urban area outside Nairobi, Kenya. Using a grounded theory approach, we transcribed and coded the narrative data followed by thematic analysis of the emergent themes. Hand drying, specifically on a clean towel, was not a common practice among our participants. Most women dried their hands on their waist cloth, called a leso, or their clothes whether they were cooking, eating or cleaning the nose of a young child. If men dried their hands, they used their trousers or a handkerchief. Children rarely dried their hands; they usually just wiped them on their clothes, shook them, or left them wet as they continued with their activities. Many people sneezed into their hands and wiped them on their clothes. Men and women used a handkerchief fairly often when they had a runny nose, cold, or the flu. Most people coughed into the air or their hand. Drying hands on dirty clothes, rags and lesos can compromise the benefits of handwashing. Coughing and sneezing in to an open hand can contribute to spread of disease as well. Understanding these practices can inform health promotion activities and campaigns for the prevention and control of diarrheal disease and influenza.

Right hemisphere, which is attributed to the sound intensity discrimination, has abnormality in people with attention deficit/hyperactivity disorder (AD/HD). However, it is not studied whether the defect in the right hemisphere has influenced on the intensity sensation of AD/HD subjects or not. In this study, the sensitivity of normal and AD/HD children to the sound intensity was investigated. Nineteen normal and fourteen AD/HD children participated in the study and performed a simple auditory reaction time task. Using the regression analysis, the sensitivity of right and left ears to various sound intensity levels was examined. The statistical results showed that the sensitivity of AD/HD subjects to the intensity was lower than the normal group (p Left and right pathways of the auditory system had the same pattern of response in AD/HD subjects (p > 0.05). However, in control group the left pathway was more sensitive to the sound intensity level than the right one (p = 0.0156). It can be probable that the deficit of the right hemisphere has influenced on the auditory sensitivity of AD/HD children. The possible existent deficits of other auditory system components such as middle ear, inner ear, or involved brain stem nucleuses may also lead to the observed results. The development of new biomarkers based on the sensitivity of the brain hemispheres to the sound intensity has been suggested to estimate the risk of AD/HD. Designing new technique to correct the auditory feedback has been also proposed in behavioral treatment sessions. Copyright © 2017. Published by Elsevier B.V.

To examine the independent and combined association of self-efficacy and fatness with physical activity in 5(th) grade children. Participants were 281 students (10.4 ± 0.7 years). Physical activity was assessed using a self-report question. Self-efficacy to be physically active was assessed using a 5-point scale. Body fatness was assessed by bioelectrical impedance. Descriptive statistics, ANOVA, and t-tests were used. There were no differences in reported days of physical activity between boys and girls, and normal-fat and over-fat children. However, children with high self-efficacy participated in significantly more physical activity compared to their low self-efficacy counterparts (3.4 ± 2.0 days vs. 5.4 ± 1.8 days, respectively, p < .001). Only physical activity self-efficacy was related to physical activity, fatness was not.

Although the etiology and pathology of autism spectrum disorder (ASD) is still poorly understood, a number of environmental, anthropological, neurobiological and genetic factors have been related to the pathophysiology of ASD, even the impact of oxidative stress response related to the environment and nutrition intake. Usual recommended dietary habits are based on the combination of behavioral and dietary or nutraceutical interventions together with pharmacotherapy. Investigations about a reliable relationship between diet and ASD are still lacking. The present study aimed at comparing dietary regimens and habits of normally developing apparently healthy children, without diagnosed ASD, with a pediatric population of individuals affected by autistic disorder. Assessments of nutritional and anthropometric data, in addition to biochemical evaluation for nutrient deficiencies, were performed. A total of 80 children with autistic disorder and 80 healthy, normally developing pediatric individuals were enrolled in the study. Parents were asked to complete the standardized questionnaire regarding the different types of food and the proportion of a serving for their children. Biochemical analysis of micro- and macronutrients were also done. Plotting on the Egyptian sex-specific anthropometric growth (auximetric) chart, absolute weights as well as weight-related for age classes, were significantly higher in cases than healthy controls. No differences between groups were observed in regard to total kilocalories (kcal), carbohydrates, and fat intake. A total of 23.8% of children with autistic disorder vs. 11.3% in the healthy control group had a nutrient intake with features below the Recommended Dietary Allowance (RDA) of protein. Children with autistic disorder showed low dietary intake of some micronutrients; calcium (Ca), magnesium (Mg), iron (Fe), selenium (Se) and sodium (Na), also they had significantly high intake of potassium (K) and vitamin C compared to healthy

Full Text Available Background Many factors contribute to language development in children. About 5-8% of children in Indonesia experience delayed language skills. Young children need appropriate stimulation for optimal development. Children who watch television (TV for long periods of time may receive less two-way interaction, the appropriate stimulation for learning. As such, shorter duration of the appropriate stimulation may impede language development in small children. Objective To assess for an association between duration of watching TV and language development in young children. Methods This cross-sectional study was done with primary data collected from questionnaires. Subjects, aged 18 months to 3 years, were from a Jakarta-area community health center (Puskesmas Jatinegara and the Pediatric Growth and Development Clinic, Cipto Mangunkusumo Hospital, Jakarta. Their language development was tested using the Developmental Pre-screening Questionnaire (Kuesioner Pra Skrining Perkembangan, KPSP and the Early Language Milestone (ELM Scale 2 test. Results From a total of 84 subjects, 47 (56% had normal and 37 (44% had delayed language development. Duration of watching TV was categorized as 4 hours per day. Children who watched TV >4 hours/day (OR 4.4; 95%CI 1.68 to 11.7; P=0.002, and children who watched both Indonesian and English language TV programs (OR 14.7; 95%CI 1.77 to 123.0; P=0.004 had higher risk of language delay. Other variables such as sex, first age exposed to TV, use of gadgets, and TV in the bedroom had no significant associations with delayed language development. Conclusion Children who watch TV >4 hours/day had four times higher risk of developing language delay. In addition, those who watch TV programs in both Indonesian and English, also have a 14.7 higher risk of delayed language development.

To measure shear wave velocities (SWVs) by acoustic radiation force impulse (ARFI) ultrasound elastography in normal kidneys and in hydronephrotic kidneys in young children and to compare SWVs between the hydronephrosis grades. This study was approved by an institutional review board, and informed consent was obtained from the parents of all the children included. Children under the age of 24 months were prospectively enrolled. Hydronephrosis grade was evaluated on ultrasonography, and three valid ARFI measurements were attempted using a high-frequency transducer for both kidneys. Hydronephrosis was graded from 0 to 4, and high-grade hydronephrosis was defined as grades 3 and 4. Fifty-one children underwent ARFI measurements, and three valid measurements for both kidneys were obtained in 96% (49/51) of the patients. Nineteen children (38.8%) had no hydronephrosis. Twenty-three children (46.9%) had unilateral hydronephrosis, and seven children (14.3%) had bilateral hydronephrosis. Seven children had ureteropelvic junction obstruction (UPJO). Median SWVs in kidneys with high-grade hydronephrosis (2.02 m/sec) were higher than those in normal kidneys (1.75 m/sec; P=0.027). However, the presence of UPJO did not influence the median SWVs in hydronephrotic kidneys (P=0.362). Obtaining ARFI measurements of the kidney is feasible in young children with median SWVs of 1.75 m/sec in normal kidneys. Median SWVs increased in high-grade hydronephrotic kidneys but were not different between hydronephrotic kidneys with and without UPJO.

The objectives of this study were as follows: to present the course and outcome of pregnancies complicated with fetal ventriculomegaly, determine the association between prenatal ultrasound diagnoses and definitive postnatal diagnosis or diagnoses after autopsy and additional analysis, and to monitor the psychomotor development of children born with ventriculomegaly. The survey was designed as retrospective study and included 62 pregnant women who were attending a regular ultrasound examinations at the Department of Gynecology and Obstetrics, Clinical Center of Serbia, or patients who were referred from other institutions in Serbia. Ventriculomegalies were divided into three groups: mild, moderate, and severe or hydrocephalus. The most common were severe ventriculomegalies, with 34 cases (55%). Of all pregnancies complicated with ventriculomegalies, 61% were terminated. Among those continued, 88% had normal psychomotor development. In 97% ultrasonographic diagnosis was confirmed. Majority of pregnancies complicated with ventriculomegaly were continued and most of the children born with anomalies had normal psychomotor development.

Full Text Available Dissociated motor development (DMD is considered when the baby starts independent walking late, with normality of the other fields of development. There is evidence that babies with DMD present an atypical crawling pattern and hypotonia. To investigate the frequency and characteristics of DMD, neurological examination was performed monthly in 177 healthy full-term babies from 6 months age, in urban and rural zone samples in Brazil. Among 20 children with atypical crawling, none presented hypotonia neither did they start independent walking late. The means of the ages at the begining of atypical crawling and independent walking acquisitions, 7.40mo (SD 1.4 and 12.76mo (SD 2.5 respectively, did not differ from the group with crossed crawling pattern. Thus, in this sample of Brazilian healthy children we did not find cases with DMD.

Full Text Available There is limited evidence to support the effectiveness of primary interventions aiming to prevent excess weight gain among young children. Evaluating behavioral changes, such as physical activity (PA, may add to future development of efficient interventions. The objective was to evaluate the effect on PA outcomes of the 15 month Healthy Start intervention that focused on changing diet, PA, sleep and stress management among normal weight but obesity-prone preschool children. Children were defined as obesity-prone if they had a birth weight > 4,000 g, mothers with a pre-pregnancy body mass index of > 28 kg/m2, or mothers with ≤ 10 years of schooling.From a baseline study population of 635 normal weight 2-6 year old preschool children from the greater Copenhagen area, parents of 307 children had given information on PA at both the baseline and follow-up examinations. PA was obtained from a 7 days recording in the Children's Physical Activity Questionnaire. Time used for sport activities were combined with outdoor playing time to achieve a proxy of total PA level of moderate to vigorous intensity.Linear regression analyses revealed that at follow-up the intervention group spent more time on sports and outdoor activities combined per week than the control group (ITT analyses: intervention: 400 min/week; 95% confidence interval (CI: 341, 459 versus control: 321 min/week; 95% CI: 277, 366; p = 0.02, although no significant intervention effects were seen for each of the subcategories, e.g. sports participation, outdoor activities, screen time, or commuting frequency.Our results suggest that the overall time spent on sports and outdoor activities combined was increased at follow-up among normal weight obesity-prone children, as a result of the Healthy Start intervention.ClinicalTrials.gov NCT01583335.

Full Text Available The emergence of artemisinin-resistant P. falciparum malaria in South-East Asia highlights the need for continued global surveillance of the efficacy of artemisinin-based combination therapies.On the Kenyan coast we studied the treatment responses in 474 children 6-59 months old with uncomplicated P. falciparum malaria in a randomized controlled trial of dihydroartemisinin-piperaquine vs. artemether-lumefantrine from 2005 to 2008. (ISRCTN88705995.The proportion of patients with residual parasitemia on day 1 rose from 55% in 2005-2006 to 87% in 2007-2008 (odds ratio, 5.4, 95%CI, 2.7-11.1; P37.5°C, 2.8, 1.9-4.1; P<0.001. Neither in vitro sensitivity of parasites to DHA nor levels of antibodies against parasite extract accounted for parasite clearance rates or changes thereof.The significant, albeit small, decline through time of parasitological response rates to treatment with ACTs may be due to the emergence of parasites with reduced drug sensitivity, to the coincident reduction in population-level clinical immunity, or both. Maintaining the efficacy of artemisinin-based therapy in Africa would benefit from a better understanding of the mechanisms underlying reduced parasite clearance rates.Controlled-Trials.com ISRCTN88705995.

The aim of this study was to establish normative data on the speech disfluencies of normally fluent French-speaking children at age 4, an age at which stuttering has begun in 95% of children who stutter (Yairi & Ambrose, 2013). Fifty monolingual French-speaking children who do not stutter participated in the study. Analyses of a conversational speech sample comprising 250-550 words revealed an average of 10% total disfluencies, 2% stuttering-like disfluencies and around 8% non-stuttered disfluencies. Possible explanations for these high speech disfluency frequencies are discussed, including explanations linked to French in particular. The results shed light on the importance of normative data specific to each language.

2004-09-15

Scoring of arousals in children is based on an extension of adult criteria, as defined by the American Sleep Disorders Association (ASDA). By this, a minimum duration of 3 seconds is required. A few recent studies utilized modified criteria for the study of children, with durations as short as 1 second. However, the validity and reliability of scoring these shorter arousals have never been verified. Based on studies in adults, we hypothesized that interscorer agreement for scoring arousals shorter than 3 seconds was poor. Retrospective review of polysomnograms by 2 experienced sleep practitioners who independently scored arousals according to the ASDA 3-second criteria and modified duration criteria of 1 and 2 seconds. Academic hospital. 20 polysomnographic studies from children aged 3 to 8 years with mild to severe obstructive sleep apnea syndrome, and 16 polysomnographic studies from normal children. None. The intraclass correlation coefficient for scoring ASDA arousals was 0.90 (95% confidence interval: 0.81-0.95), indicating excellent interscorer agreement. The intraclass correlation coefficient for scoring modified 1-second and 2-second arousals were 0.35 (95% confidence interval: 0.02-0.61) and 0.42 (95% confidence interval: 0.12-0.65) respectively, indicating poor to fair interscorer agreement. Furthermore, modified 1-second and 2-second arousals accounted for less than 15% of all arousals scored. We conclude that there is much poorer interscorer agreement for scoring arousals shorter than 3 seconds, when compared to the standard ASDA criteria. We propose that scoring of arousals in children should follow the standard ASDA criteria.

Learning disabled (LD) children are often targets for cognitive-behavioral interventions designed to train them in effective use of a self-directed speech. The purpose of this study was to determine if, indeed, these children display immature private speech in the naturalistic classroom setting. Comparisons were made of the private speech, motor accompaniment to task, and attention of LD and normally achieving classmates during academic seatwork. Setting effects were examined by comparing classroom data with observations during academic seatwork and puzzle solving in the laboratory. Finally, a subgroup of LD children symptomatic of attention-deficit hyperactivity disorder (ADHD) was compared with pure LD and normally achieving controls to determine if the presumed immature private speech is a function of a learning disability or externalizing behavior problems. Results indicated that LD children used more task-relevant private speech than controls, an effect that was especially pronounced for the LD/ADHD subgroup. Use of private speech was setting- and task-specific. Implications for intervention and future research methodology are discussed.

It is important for clinician such as speech-language pathologists and audiologists to develop more efficient procedures to assess the development of auditory, speech and language skills in children using hearing aid and/or cochlear implant compared to their peers with normal hearing. So, the aim of study was the comparison of the performance of 5-to-7-year-old Persian-language children with and without hearing loss in visual-only, auditory-only, and audiovisual presentation of sentence repetition task. The research was administered as a cross-sectional study. The sample size was 92 Persian 5-7 year old children including: 60 with normal hearing and 32 with hearing loss. The children with hearing loss were recruited from Soroush rehabilitation center for Persian-language children with hearing loss in Shiraz, Iran, through consecutive sampling method. All the children had unilateral cochlear implant or bilateral hearing aid. The assessment tool was the Sentence Repetition Test. The study included three computer-based experiments including visual-only, auditory-only, and audiovisual. The scores were compared within and among the three groups through statistical tests in α = 0.05. The score of sentence repetition task between V-only, A-only, and AV presentation was significantly different in the three groups; in other words, the highest to lowest scores belonged respectively to audiovisual, auditory-only, and visual-only format in the children with normal hearing (P audiovisual sentence repetition scores in all the 5-to-7-year-old children (r = 0.179, n = 92, P = 0.088), but audiovisual sentence repetition scores were found to be strongly correlated with auditory-only scores in all the 5-to-7-year-old children (r = 0.943, n = 92, P = 0.000). According to the study's findings, audiovisual integration occurs in the 5-to-7-year-old Persian children using hearing aid or cochlear implant during sentence repetition similar to their peers with normal hearing

In dyslexia, anomalous activations have been described in both left temporo-parietal language cortices and in left ventral visual occipito-temporal cortex. However, the reproducibility, task-dependency, and presence of these brain anomalies in childhood rather than adulthood remain debated. We probed the large-scale organization of ventral visual and spoken language areas in dyslexic children using minimal target-detection tasks that were performed equally well by all groups. In 23 normal and 23 dyslexic 10-year-old children from two different socio-economic status (SES) backgrounds, we compared fMRI activity to visually presented houses, faces, and written strings, and to spoken sentences in the native or in a foreign language. Our results confirm a disorganization of both ventral visual and spoken language areas in dyslexic children. Visually, dyslexic children showed a normal lateral-to-medial mosaic of preferences, as well as normal responses to houses and checkerboards, but a reduced activation to words in the visual word form area (VWFA) and to faces in the right fusiform face area (FFA). Auditorily, dyslexic children exhibited reduced responses to speech in posterior temporal cortex, left insula and supplementary motor area, as well as reduced responses to maternal language in subparts of the planum temporale, left basal language area and VWFA. By correlating these two findings, we identify spoken-language predictors of VWFA activation to written words, which differ for dyslexic and normal readers. Similarities in fMRI deficits in both SES groups emphasize the existence of a core set of brain activation anomalies in dyslexia, regardless of culture, language and SES, without however resolving whether these anomalies are a cause or a consequence of impaired reading.

Vertigo and imbalance are often underestimated in the pediatric population, due to limited communication abilities, atypical symptoms, and relatively quick adaptation and compensation in children. Moreover, examination and interpretation of vestibular tests are very challenging, because of difficulties with cooperation and maintenance of alertness, and because of the sometimes nauseatic reactions. Therefore, it is of great importance for each vestibular laboratory to implement a child-friendly test protocol with age-appropriate normative data. Because of the often masked appearance of vestibular problems in young children, the vestibular organ should be routinely examined in high-risk pediatric groups, such as children with a hearing impairment. Purposes of the present study were (1) to determine age-appropriate normative data for two child-friendly vestibular laboratory techniques (rotatory and collic vestibular evoked myogenic potential [cVEMP] test) in a group of children without auditory or vestibular complaints, and (2) to examine vestibular function in a group of children presenting with bilateral hearing impairment. Forty-eight typically developing children (mean age 8 years 0 months; range: 4 years 1 month to 12 years 11 months) without any auditory or vestibular complaints as well as 39 children (mean age 7 years 8 months; range: 3 years 8 months to 12 years 10 months) with a bilateral sensorineural hearing loss were included in this study. All children underwent three sinusoidal rotations (0.01, 0.05, and 0.1 Hz at 50 degrees/s) and bilateral cVEMP testing. No significant age differences were found for the rotatory test, whereas a significant increase of N1 latency and a significant threshold decrease was noticeable for the cVEMP, resulting in age-appropriate normative data. Hearing-impaired children demonstrated significantly lower gain values at the 0.01 Hz rotation and a larger percentage of absent cVEMP responses compared with normal-hearing children

This study examined rapid word-learning in 5- to 14-year-old children with normal and impaired hearing. The effects of age and receptive vocabulary were examined as well as those of high-frequency amplification. Novel words were low-pass filtered at 4 kHz (typical of current amplification devices) and at 9 kHz. It was hypothesized that (1) the children with normal hearing would learn more words than the children with hearing loss, (2) word-learning would increase with age and receptive vocabulary for both groups, and (3) both groups would benefit from a broader frequency bandwidth. Sixty children with normal hearing and 37 children with moderate sensorineural hearing losses participated in this study. Each child viewed a 4-minute animated slideshow containing 8 nonsense words created using the 24 English consonant phonemes (3 consonants per word). Each word was repeated 3 times. Half of the 8 words were low-pass filtered at 4 kHz and half were filtered at 9 kHz. After viewing the story twice, each child was asked to identify the words from among pictures in the slide show. Before testing, a measure of current receptive vocabulary was obtained using the Peabody Picture Vocabulary Test (PPVT-III). The PPVT-III scores of the hearing-impaired children were consistently poorer than those of the normal-hearing children across the age range tested. A similar pattern of results was observed for word-learning in that the performance of the hearing-impaired children was significantly poorer than that of the normal-hearing children. Further analysis of the PPVT and word-learning scores suggested that although word-learning was reduced in the hearing-impaired children, their performance was consistent with their receptive vocabularies. Additionally, no correlation was found between overall performance and the age of identification, age of amplification, or years of amplification in the children with hearing loss. Results also revealed a small increase in performance for both

Research in Western nations suggests that parents' involvement in their children's media use can make a difference in how adolescents select, process and respond to sexual television messages. Little or no published research has investigated this issue in sub-Saharan Africa, even though adolescents and young adults remain among the groups at highest risk for HIV transmission. This study investigated the relationship between Kenyan adolescents' level of exposure to sexual television content and their parents' mediation of their television use. A cluster sample of 427 Nairobi public high school students was surveyed regarding parental mediation of their media use and their intake of sexual television content. Co-viewing with opposite sex friends was associated with higher intake of sexual TV content. This relationship was stronger among boarding school students than among day school students. Parental mediation and co-viewing variables predicted three times as much variance among boarding than among day school students.

Normalizing clinical gait analysis data is required to remove variability due to physical characteristics such as leg length and weight. This is particularly important for children where both are associated with age. In most clinical centres conventional normalization (by mass only) is used whereas there is a stronger biomechanical argument for non-dimensional normalization. This study used data from 82 typically developing children to compare how the two schemes performed over a wide range of temporal-spatial and kinetic parameters by calculating the coefficients of determination with leg length, weight and height. 81% of the conventionally normalized parameters had a coefficient of determination above the threshold for a statistical association (pnormalized non-dimensionally. All the conventionally normalized parameters exceeding this threshold showed a reduced association with non-dimensional normalization. In conclusion, non-dimensional normalization is more effective that conventional normalization in reducing the effects of height, weight and age in a comprehensive range of temporal-spatial and kinetic parameters.

This study aimed to investigate the effect of hearing loss (HL) on emotion-perception ability among young children with and without HL. A total of 26 children 4.0-6.6 years of age with prelingual sensory-neural HL ranging from moderate to profound and 14 children with normal hearing (NH) participated. They were asked to identify happiness, anger, sadness, and fear expressed by an actress when uttering the same neutral nonsense sentence. Their auditory, visual, and auditory-visual perceptions of the emotional content were assessed. The accuracy of emotion perception among children with HL was lower than that of the NH children in all 3 conditions: auditory, visual, and auditory-visual. Perception through the combined auditory-visual mode significantly surpassed the auditory or visual modes alone in both groups, indicating that children with HL utilized the auditory information for emotion perception. No significant differences in perception emerged according to degree of HL. In addition, children with profound HL and cochlear implants did not perform differently from children with less severe HL who used hearing aids. The relatively high accuracy of emotion perception by children with HL may be explained by their intensive rehabilitation, which emphasizes suprasegmental and paralinguistic aspects of verbal communication.

Biomass burning in indoor environments has been highlighted as a major cause of respiratory morbidity for women and children in low-income countries. Inexpensive technological innovations which reduce such exposures are needed. This study evaluated the impact of low tech compost digesters, which generate biogas for cooking, versus traditional fuel sources on the respiratory health of nonsmoking Kenyan farmwomen. Women from 31 farms with biogas digesters were compared to age-matched women from 31 biomass-reliant farms, in June 2010. Only 43% of the biogas group reported any breathing problems, compared to 71% in the referent group (P = 0.03). Referent women self-reported higher rates of shortness of breath (52% versus 30%), difficulty breathing (42% versus 23%), and chest pain while breathing (35% versus 17%) during the last 6 months (P = 0.09 to 0.12) compared to biogas women. Biogas women demonstrated slightly better spirometry results but differences were not statistically significant, likely due to limited latency between biogas digester installation and spirometry testing. Most biogas women reported improved personal respiratory health (87%) and improved children's health (72%) since biogas digester installation. These findings suggest that using biogas in cookhouses improves respiratory symptoms but long-term impacts on lung function are unclear. PMID:22969815

Pregnancies after kidney transplantation are at high risk of complications such as preterm birth and foetal growth restriction. Until now, the impact of these factors on neurological development of children born to transplant mothers has not been established. A comparison of neurological examinations performed in 36 children of kidney transplant women (study group) and 36 children born to healthy mothers (control group). The children from both groups were born at a similar gestational age and in the similar time period from 12/1996 to 09/2012. Neurological examinations were performed from 07/2010 to 11/2013. Each examination was adjusted to the patient's age and performed after the neonatal period. Three years later children were re-consulted, if they presented neurological deviations or were less than 12 months old at the time of the first examination. Normal neurological development was found in 86% of children in both groups (p = .999). Mild neurological deviations were observed in four (11%) children born to kidney transplant mothers and in five (14%) children born to healthy mothers (p = .999). Moderate deviations were diagnosed in one premature child born to transplant mother, whose pregnancy was complicated with a severe preeclampsia and foetal growth restriction. In the study population, no severe neurological disorders were found. Almost all (8/10) children with neurological deviations were born prematurely in good general conditions. The neurological deviations observed in the first year of life were mild and transient. In children over 1 year of age, deviations were more pronounced and continued to maintain. The neurological development of children of kidney transplant women is similar to that of the general population and possible deviations seem to be the result of intrauterine hypotrophy and prematurity. Therefore, in clinical practice, it is necessary to plan post-transplant pregnancies especially in women at high risk of these complications.

Allometric scaling (Y=aXb has emerged as an efficient method to compare individuals of different body dimensions. Studies aimed to compare VO2max in individuals with different body sizes should use methodology that properly accounts for the body size effect, thereby avoiding misinterpretation and reaching the potentially wrong conclusion. The use of allometric scaling for studies aimed to compare aerobic fitness in children and adolescents who dramatically vary in body size is strongly recommended.

Full Text Available Introduction: Bisphenol A and several of the most commonly used phthalates have been associated with adverse metabolic health effects such as obesity and diabetes. Therefore, we analyzed these man-made chemicals in first morning urine samples from 107 healthy normal-weight Danish children and adolescents. Method: This was a cross-sectional study. Participants were recruited as part of the Copenhagen Puberty Study. The subjects were evaluated by an oral glucose tolerance test (OGTT, a dual-energy X-ray absorptiometry (DXA scan, direct oxygen uptake measurement during cycle ergometry and fasting blood samples. First morning urine was collected and phthalate metabolites and BPA were measured by liquid chromatography-tandem mass spectrometry (LC–MS/MS with prior enzymatic deconjugation. Individual chemical concentrations were divided into tertiles and analyzed in relation to biological outcome. Results: Children in the lowest tertile of urinary BPA had significantly higher peak insulin levels during OGTT (P = 0.01, lower insulin sensitivity index (P < 0.01, higher leptin (P = 0.03, triglyceride (P < 0.01 and total cholesterol levels (P = 0.04, lower aerobic fitness (P = 0.02 and a tendency toward higher fat mass index (P = 0.1 compared with children in the highest tertile for uBPA. No significant differences in anthropometrics, body composition or glucose metabolism were associated with any of the phthalate metabolites measured. Conclusion: This pilot study on healthy normal-weight children suggests an inverse association between BPA and insulin resistance. Our findings contrast other cross-sectional studies showing a positive association for BPA, which may be due to confounding or reverse causation because diet is an important source of both BPA exposure and obesity.

Irisin has been suggested to protect against overweight. There are no previous data on the association of plasma fatty acid (FA) composition with plasma irisin. We studied the association of FA composition with plasma irisin in normal weight and overweight/obese children. This cross-sectional study included pre-pubertal children (388 normal weight children and 55 overweight/obese children); 6-9 years of age, taking part in the Physical Activity and Nutrition in Children Study. After an overnight fast, we measured plasma FA composition by gas chromatography and plasma irisin levels by enzyme-linked immunosorbent assay. Higher proportion of total monounsaturated fatty acids in plasma cholesteryl esters (CEs) (β = 0.139, P = 0.003) and phospholipids (PLs) (β = 0.147, P = 0.002) and lower proportion of total polyunsaturated fatty acids in plasma CE (β = -0.130, P = 0.006) and PL (β = -0.165, P overweight/obese children compared to normal weight children. Higher proportion of γ-linolenic acid (β = 0.324, P = 0.017) and lower proportion of linoleic acid (β = -0.397, P = 0.005) in plasma CE were related to higher plasma irisin level among overweight/obese children, indicating the direct association of estimated D6D activity in plasma CE (β = 0.343, P = 0.011) with plasma irisin. Furthermore, higher proportion of oleic acid in plasma CE (β = 0.345, P = 0.012) and PL (β = 0.292, P = 0.033) and higher proportion of adrenic acid (β = 0.366, P = 0.008) and docosapentaenoic acid (β = 0.351, P = 0.010) in plasma PL were associated with higher plasma irisin level among overweight/obese children. Metabolically unfavourable plasma FA profile was associated with higher plasma irisin level especially in overweight/obese children, suggesting that excess body fat might modulate these relationships. © 2015 World Obesity.

Full Text Available Background. Inflammation, together with related oxidative stress, is linked with the etiology of kwashiorkor, a form of severe acute malnutrition in children. A diet rich in anti-inflammatory and antioxidant phytochemicals may offer potential for the prevention and treatment of kwashiorkor. We selected and assayed five leafy green vegetables, two wild fruits, and six medicinal plants from Kenya for their antioxidant and anti-inflammatory properties. Consensus regarding medicinal plant use was established from ethnobotanical data. Methods. Antioxidant activity and phenolic content were determined using the oxygen radical absorbance capacity (ORAC assay and Folin-Ciocalteu procedure, respectively. Anti-inflammatory activity was assessed in vitro targeting the inflammatory mediator tumour necrosis factor-alpha (TNF-α. Results. Mangifera indica (leaves used medicinally showed the greatest antioxidant activity (5940 ± 632 µM TE/µg and total phenolic content (337 ± 3 mg GAE/g but Amaranthus dubius (leafy vegetable showed the greatest inhibition of TNF-α (IC50 = 9 ± 1 μg/mL, followed by Ocimum americanum (medicinal plant (IC50 = 16 ± 1 μg/mL. Informant consensus was significantly correlated with anti-inflammatory effects among active medicinal plants (r2=0.7639, P=0.0228. Conclusions. Several plant species commonly consumed by Kenyan children possess activity profiles relevant to the prevention and treatment of kwashiorkor and warrant further investigation.

The effects of energy taxes on the Kenyan economy: a CGE analysis

The paper utilizes a computable general equilibrium model to evaluate the impact of the second oil price shock and consequent energy tax policies on the Kenyan economy. Simulations show that dramatic change in energy prices and consequent changes in domestic energy consumption generate sequential feedbacks in the production process and affect economic structures. Terms of trade deteriorate; the balance of payments deficit increases and national income falls. Energy import tariffs and a sales tax are effective policy instruments in controlling energy consumption and increasing government revenue. Both energy policies have net negative effects on other economics activities similar to those observed under the oil price shock. (author)

Reading is known to be primarily a linguistic task. However, to successfully decode written words, children also need to develop good visual-perception skills. Furthermore, motor skills are implicated in letter recognition and reading acquisition. Three studies have been designed to determine the link between reading, visual perception, and visual-motor integration using the Developmental Test of Visual Perception version 2 (DTVP-2). Study 1 tests how visual perception and visual-motor integration in kindergarten predict reading outcomes in Grade 1, in typical developing children. Study 2 is aimed at finding out if these skills can be seen as clinical markers in dyslexic children (DD). Study 3 determines if visual-motor integration and motor-reduced visual perception can distinguish DD children according to whether they exhibit or not developmental coordination disorder (DCD). Results showed that phonological awareness and visual-motor integration predicted reading outcomes one year later. DTVP-2 demonstrated similarities and differences in visual-motor integration and motor-reduced visual perception between children with DD, DCD, and both of these deficits. DTVP-2 is a suitable tool to investigate links between visual perception, visual-motor integration and reading, and to differentiate cognitive profiles of children with developmental disabilities (i.e. DD, DCD, and comorbid children).

The purpose of this study was to evaluate the relationship between zinc and the growth and development of young children. The parents of 8102 young children were surveyed in person by a trained surveyor using structured questionnaires. The hair zinc concentration of the children was determined using an atomic absorption spectrophotometer. The height, weight, sitting height, and head circumference of the children were measured at follow-up visits. There was a positive correlation between hair zinc concentration and adaptive developmental quotient (ADQ; r = 0.3164, P = 0.0272) while no correlation was found between hair zinc concentration and body measurement Z scores or intelligence quotient (IQ). There was a strong positive correlation between hair zinc concentration and weight-for-age Z scores (r = 0.3618, P = 0.0416) and ADQ (r = 0.2761, P = 0.0387) in boys; there was no correlation between hair zinc concentration and body measurement Z scores, IQ, and ADQ in girls. In boys with normal hair zinc levels, ADQ was 9.58 (P = 0.0392), higher than in boys who had zinc-deficient hair. In girls with normal hair zinc levels, ADQ was 2.52 (P = 0.0296), lower than in girls with zinc-deficient hair. In conclusion, there is no significant correlation between hair zinc levels and IQ or Z scores for all body measurements in young children.

COMPARISON OF STRESS LEVELS IN THE PARENTS OF CHILDREN WITH CEREBRAL PALSY AND PARENTS OF NORMAL CHILDREN IN VADODARA REGION OF GUJARAT

Directory of Open Access Journals (Sweden)

Dr. Vivek H. Ramanandi

2015-04-01

Full Text Available Background: Parenting is inherently stressful at times and several studies have shown that being a caregiver of a child who is disabled is even more stressful. A number of studies have identified the factors which exacerbate or mediate parenting stress in caregivers of children who are disabled. The aim of this study was to assess the parenting stress levels in parents of children who have cerebral palsy as compared to parents of normal children. Further objectives were to ascertain variables predictive of parenting stress levels. Methods: The Gujarati translated version of Parenting Stress Index/Short Form was first validated and was given to 49 parents of children with cerebral palsy (Group-A who were attending Varun Mahajan Apang Shishu Mandal, Vadodara and to the 50 parents of normal children(Group-B. Caregivers also completed a demographic questionnaire. 43 questionnaires from Group-A and 45 from Group-B were returned to the researcher. Means and frequencies were used to summarise the demographic data. T-tests were performed to establish whether there was any significant difference between the parenting stress levels in Group-A and Group-B. Results: The parents in Group-A showed clinically significant, and in many cases, pathological levels of parenting stress as compared to the parents in Group-B. Conclusions: The results of this study confirm that parenting stress is complex matter and it is important to predict the parenting stress levels of caregivers of disabled children. Therapists should evaluate the needs of each family individually and follow a family centred approach when managing children with cerebral palsy.

Revisiting normal {sup 51}Cr-ethylenediaminetetraacetic acid clearance values in children

Normal {sup 51}Cr-ethylenediaminetetraacetic acid (EDTA) clearance values as a function of age were published a number of years ago. These values were based on data from children with a normal left to right ratio and a normal appearance on DMSA scintigraphy, despite the presence of an acute renal infection. At that time, the authors were unaware that hyperfiltration is a common phenomenon in patients with acute renal infection and that their normal values could have been significantly overestimated. The present work therefore aimed to re-appraise these normal values. In a first step, in order to verify the previous results, the same type of population was selected, namely patients with present or past urinary tract infection but normal images and a normal left to right ratio on DMSA scintigraphy. In a second step, the selection was based on patients who had had no recent urinary tract infection. In both series, a single blood sample method was used for the evaluation of {sup 51}Cr-EDTA clearance. In the first group of patients, the results obtained were almost identical to those previously published. In the second group of patients, the results were significantly lower: after 2 years of age, the mean GFR value was 104 ml/min/1.73 m{sup 2} (10th and 90th percentiles 81 and 135 ml/min/1.73 m{sup 2}, respectively), compared with 117 ml/min/1.73 m{sup 2} in the first group. The data of the second group are probably more representative of the true normal GFR values and can be applied to the entire paediatric population. (orig.)

Development and analysis of a low-cost screening tool to identify and classify hearing loss in children: a proposal for developing countries

Alessandra Giannella Samelli

2011-01-01

Full Text Available OBJECTIVE: A lack of attention has been given to hearing health in primary care in developing countries. A strategy involving low-cost screening tools may fill the current gap in hearing health care provided to children. Therefore, it is necessary to establish and adopt lower-cost procedures that are accessible to underserved areas that lack other physical or human resources that would enable the identification of groups at risk for hearing loss. The aim of this study was to develop and analyze the efficacy of a low-cost screening tool to identify and classify hearing loss in children. METHODS: A total of 214 2-to-10 year-old children participated in this study. The study was conducted by providing a questionnaire to the parents and comparing the answers with the results of a complete audiological assessment. Receiver operating characteristic (ROC curves were constructed, and discriminant analysis techniques were used to classify each child based on the total score. RESULTS: We found conductive hearing loss in 39.3% of children, sensorineural hearing loss in 7.4% and normal hearing in 53.3%. The discriminant analysis technique provided the following classification rule for the total score on the questionnaire: 0 to 4 points - normal hearing; 5 to 7 points - conductive hearing loss; over 7 points - sensorineural hearing loss. CONCLUSION: Our results suggest that the questionnaire could be used as a screening tool to classify children with normal hearing or hearing loss and according to the type of hearing loss based on the total questionnaire score

The aim of this study was to describe oral development and morphology in 18-month-old children with Down syndrome (DS) treated with palatal plates in combination with structured communication and speech training. The aim is further to describe the design of the palatal plates, compliance in their use and to give a brief report of their effect on oral motor function and speech. Forty-two children with DS were followed from language intervention, and oral motor and sensory stimulation provided by speech therapists for all children with DS in Sweden, palatal plates provided by dentists are included in the training programme. In the evaluation, the children in the project were compared with two control groups of children matched for age; one group of children with DS who had not been treated with palatal plates, and one group of children with normal development. Compared to the children with normal development, both groups of children with DS had fewer teeth erupted and a lower prevalence of sucking habits. Deviant morphology of the tongue in the form of diastase, lingua plicata or a sulcus in the anterior third of the tongue was only seen in children with DS. All children with normal development had positive values for overjet compared to 53% of the children with DS. The palatal plates were used 2-3 times daily for a total mean time of 15 min. Compliance in use of the plates decreased with age, mainly due to eruption of teeth and subsequent loss of retention. Evaluation of oral motor function and speech show that the children with DS in the project had better motor prerequisites for articulation than the control children with DS. Palatal plate therapy did not affect oral parameters, i.e., eruption of teeth, types and prevalence of sucking habits, tongue morphology and symptoms of hypotonia. In combination with oral motor and sensory stimulation, palatal plate therapy had a positive effect on oral motor performance and prerequisites for articulation.

This article explores four Kenyan primary school teachers’ life-stories and narrative learning through living and telling stories about their lives from 2000 to 2011, and what this means for their relation to the teaching profession. Evidence suggests that narrative learning manifests as altered...... professionalism ‘in’ and ‘through’ the stories teachers tell about their lives and depends on ruptures in lived life, followed by periods of transition in life-stories. Teachers also learned narratively by recounting their life-stories. Thus, narrative learning is an important learning site and a resource...... for professional development in addition to pre-service teacher education....

Physical and sexual violence against children in Kenya within a cultural context.

Science.gov (United States)

Bridgewater, Grace

2016-02-01

The issue of physical and sexual abuse of children in Kenya is recognised as a highly prevalent and significant problem, occurring within a framework of social values that contribute to the exploitation of women and children. In order to understand the risk and protective factors for children who experience physical and sexual abuse, the cultural context must be taken into consideration. This paper will argue that patriarchy and traditional values underlie the norms and behaviours of parents and communities interacting with children. These values can be protective, eg the value placed on family structure; however, the traditional value-system justifies harsh physical punishment as a means of disciplining children. While systems exist to prevent abuse, these often disenfranchise the poor, who are then left to seek traditional means of support (eg out-of-court agreements and settlements). A culture of silence also prevents many children from reporting abuse. The paper argues that efforts must be made to gain a better understanding of the prevalence of child maltreatment in Kenya so that targeted services can be developed to reduce it, taking into consideration and overcoming negative cultural factors through the implementation of educational programmes and anti-oppressive practice. It is hoped that this paper will enable community practitioners and health visitors in the UK to provide better support to Kenyan children who are at risk of experiencing physical and sexual violence.

We examined parenting stress and mental health status in parents of autistic children and assessed factors associated with such stress. Participants were parents of 188 autistic children diagnosed with DSM-IV criteria and parents of 144 normally developing children. Parents of autistic children reported higher levels of stress, depression, and anxiety than parents of normally developing children. Mothers of autistic children had a higher risk of depression and anxiety than that did parents of normally developing children. Mothers compared to fathers of autistic children were more vulnerable to depression. Age, behavior problems of autistic children, and mothers' anxiety were significantly associated with parenting stress.

Mnemonic abilities of primary school children with delayed mental development.

2015-07-01

Full Text Available This paper presents the results of research regarding the mnemonic abilities of primary school children with developmental delays. Empirical studies of impaired mental development offer an opportunity to elucidate the psychological mechanisms underlying the process of normal development and enable us to consider at a micro level the formation of mental processes in ontogeny, which would, under normal conditions, be nondescript and not always amenable to psychological analysis. The research addresses an experimental investigation of productivity and qualitative characteristics of mnemonic abilities among primary school students with developmental delays. V.D. Shadrikov’s Theory of Abilities, developed in a systemic approach framework, is the theoretical basis of the research. The method of deploying a memorization activity, as elaborated by V.D. Shadrikov and L.V. Cheremoshkina, was the investigation tool used. The sample included students in grades 1 to 4 between ages 7 to 12 and included a total of 100 children (66 boys and 34 girls. The control group of primary school students with typical development included 105 children (50 boys and 55 girls. The research consisted of several stages: a pilot study, experimental research (the test task was to memorize card #1; the basic task was to memorize cards #2 and #3; to reproduce cards #2 and #3; and to poll the students, mathematical data processing, and a description of the levels of mnemonic ability development among primary students with developmental delays. The following procedures were employed during statistical analysis: Spearman r3, Mann-Whitney U-test, Jonckheere-Terpstra test, and Kruskal-Wallis test. The structure of mnemonic abilities in primary schoolchildren with developmental delays was determined to vary according to the underdevelopment of their operational mechanisms. For example, memory functions are based on the use of inborn mechanisms, and a portion of children differ in the

A large proportion of healthy children have wrist changes on MRI, namely carpal depressions, findings that have been described as pathological in children with juvenile idiopathic arthritis. We performed follow-up imaging in a cohort of healthy children to evaluate carpal surface depressions over time, focusing on the presence of overlying cartilage as a potential discriminator between normal variants and true erosions. 74 of the initial cohort of 89 healthy children (83%) had a re-scan of their wrists using the same protocol, including coronal T1 and fat-saturated T2 sequences. A cartilage-selective sequence was added for this study. We registered number and location of bony depressions and presence of overlying cartilage. The total number of carpal depressions increased by age group and over time; their location was unchanged in 370 of 487 (76%) carpal sites and 91 of 117 (78%) metacarpal sites. In total, 426 of the 1,087 (39.2%) bony depressions were covered by cartilage, with a decreasing percentage by age (P = 0.001). Normal appearances during growth, such as bony depressions, should not be mistaken for pathology. There must be additional findings to support a diagnosis of disease. A cartilage sequence may add to the diagnostic image analysis. (orig.)

Aside from the health consequences, observational studies indicate that being overweight may also negatively affect cognitive function. However, existing evidence has to a large extent not controlled for the possible confounding effect of having different lifestyles. Therefore, the objective was to examine the independent associations between weight status and lifestyle indicators with cognitive performance in 8-11year old Danish children. The analyses included 828 children (measured in 2011-2012) each having one to three measurement occasions separated by approximately 100days. Dietary intake, physical activity, sedentary time, and sleep duration were measured using dietary records and accelerometers. The Children's Sleep Habits Questionnaire was used to access sleep problems and the Andersen test was carried out to estimate cardio-respiratory fitness (CRF). Weight status (underweight, normal weight, and overweight/obese) was defined according to body mass index and cognitive performance was assessed using the d2-test of attention, a reading test, and a math test. A linear mixed model including a number of fixed and random effects was used to test associations between lifestyle indicators as well as BMI category and cognitive performance. After adjustment for demographics, socioeconomics, and multiple lifestyle indicators, normal weight children had higher cognitive test scores than overweight/obese and underweight children of up to 89% and 48% of expected learning within one school year (Pbreakfast consumption, fewer sleep problems, higher CRF, less total physical activity, more sedentary time, and less light physical activity were associated with higher cognitive performance independently of each other in at least one of the three cognitive tests (Pperformance compared to overweight/obese as well as underweight children, independent of multiple lifestyle indicators.

Is Peace Journalism possible in the ‘war’ against terror in Somalia? How the Kenyan Daily Nation and the Standard represented Operation Linda Nchi

Directory of Open Access Journals (Sweden)

Fredrick Ogenga

2012-10-01

Full Text Available This paper concludes that in Africa the non-Western press may have the best chance to employ peace journalism, given its proximity to major conflicts. Nevertheless, the Kenyan press has so far failed to take advantage of an ideal opportunity for such an experiment in reporting on the war against terror. Kenya's press still operates within the war journalism framework. This paper employs a theoretical approach that combines theories of media representation in mainstream journalism with the concepts of peace journalism. Methodologically, it adopts a triangulating approach, employing both quantitative and qualitative content analysis to study the representations of Operation Linda Nchi by the Kenyan Daily Nation and The Standard and thereby offers a critical appraisal of the possibility for peace journalism to cover international terrorism in Africa.

Understanding speech in acoustically degraded environments can place significant cognitive demands on school-age children who are developing the cognitive and linguistic skills needed to support this process. Previous studies suggest the speech understanding, word learning, and academic performance can be negatively impacted by background noise, but the effect of limited audibility on cognitive processes in children has not been directly studied. The aim of the present study was to evaluate the impact of limited audibility on speech understanding and working memory tasks in school-age children with normal hearing. Seventeen children with normal hearing between 6 and 12 years of age participated in the present study. Repetition of nonword consonant-vowel-consonant stimuli was measured under conditions with combinations of two different signal to noise ratios (SNRs; 3 and 9 dB) and two low-pass filter settings (3.2 and 5.6 kHz). Verbal processing time was calculated based on the time from the onset of the stimulus to the onset of the child's response. Monosyllabic word repetition and recall were also measured in conditions with a full bandwidth and 5.6 kHz low-pass cutoff. Nonword repetition scores decreased as audibility decreased. Verbal processing time increased as audibility decreased, consistent with predictions based on increased listening effort. Although monosyllabic word repetition did not vary between the full bandwidth and 5.6 kHz low-pass filter condition, recall was significantly poorer in the condition with limited bandwidth (low pass at 5.6 kHz). Age and expressive language scores predicted performance on word recall tasks, but did not predict nonword repetition accuracy or verbal processing time. Decreased audibility was associated with reduced accuracy for nonword repetition and increased verbal processing time in children with normal hearing. Deficits in free recall were observed even under conditions where word repetition was not affected

Moral emotions such as shame, guilt and pride are the result of an evaluation of the own behavior as (morally) right or wrong. The capacity to experience moral emotions is thought to be an important driving force behind socially appropriate behavior. The relationship between moral emotions and social behavior in young children has not been studied extensively in normally hearing (NH) children, let alone in those with a hearing impairment. This study compared young children with hearing impairments who have a cochlear implant (CI) to NH peers regarding the extent to which they display moral emotions, and how this relates to their social functioning and language skills. Responses of 184 NH children and 60 children with CI (14-61 months old) to shame-/guilt- and pride-inducing events were observed. Parents reported on their children's social competence and externalizing behavior, and experimenters observed children's cooperative behavior. To examine the role of communication in the development of moral emotions and social behavior, children's language skills were assessed. Results show that children with CI displayed moral emotions to a lesser degree than NH children. An association between moral emotions and social functioning was found in the NH group, but not in the CI group. General language skills were unrelated to moral emotions in the CI group, yet emotion vocabulary was related to social functioning in both groups of children. We conclude that facilitating emotion language skills has the potential to promote children's social functioning, and could contribute to a decrease in behavioral problems in children with CI specifically. Future studies should examine in greater detail which factors are associated with the development of moral emotions, particularly in children with CI. Some possible directions for future research are discussed.

The purpose of this investigation was to study the acute effects of caffeine on learning, performance, and anxiety in normal prepubertal children. Twenty-one children were evaluated in a double-blind, placebo-controlled crossover design. Subjects were studied during four sessions, 1 week apart, under the following conditions: baseline, placebo, 2.5 mg/kg caffeine, and 5.0 mg/kg caffeine. Subjects were randomized to order of placebo and the two dosages of caffeine. Dependent measures included tests of attention, manual dexterity, short-term memory, and processing speed. Anxiety rating scales were also administered. Saliva samples were analyzed for caffeine levels. Caffeine improved performance on two of four measures of the Test of Variables of Attention and on a test of manual dexterity in the dominant hand. There was a trend toward increased current level of self-reported anxiety after caffeine on a visual analogue measure of anxiety. Children reported feeling significantly less "sluggish" after caffeine ingestion than after placebo ingestion. In a small sample size, there was indication that caffeine enhanced performance on a test of attention and on a motor task. Children also reported feeling less "sluggish" but somewhat more anxious. Because caffeine is so widely available and frequently consumed by children, these results are important and need replication.

The definition of normal values is a prerequisite for the reliable evaluation of abnormality in the lumbar spine, such as spinal canal stenosis or dural ectasia in patients with Marfan syndrome. Values for vertebral body diameter (VBD) and dural sac diameter (DSD) for the lumbar spine have been published in adults. In children, normal values have been established using conventional radiography or myelography, but not by MRI. To define normal values for the sagittal diameter of the vertebral body and dural sac, and to calculate a dural sac ratio (DSR) in the lumbosacral spine (L1-S1) in healthy children using MRI. A total of 75 healthy children between 6 years and 17 years of age were examined using a sagittal T2-weighted sequence. Sagittal VBD and DSD were measured and a DSR was calculated. This was a retrospective and cross-sectional study. With increasing age there is a significant increase of VBD, a slight increase of DSD, and a slight decrease of DSR. There is no significant sex difference. DSR in healthy children is higher than in healthy adults. MRI is a reliable method demonstrating the natural shape of the lumbosacral spine and its absolute values. These normal values compare well with those established by conventional radiological techniques. Our data may serve as a reference for defining dural ectasia in children with Marfan syndrome.

The definition of normal values is a prerequisite for the reliable evaluation of abnormality in the lumbar spine, such as spinal canal stenosis or dural ectasia in patients with Marfan syndrome. Values for vertebral body diameter (VBD) and dural sac diameter (DSD) for the lumbar spine have been published in adults. In children, normal values have been established using conventional radiography or myelography, but not by MRI. To define normal values for the sagittal diameter of the vertebral body and dural sac, and to calculate a dural sac ratio (DSR) in the lumbosacral spine (L1-S1) in healthy children using MRI. A total of 75 healthy children between 6 years and 17 years of age were examined using a sagittal T2-weighted sequence. Sagittal VBD and DSD were measured and a DSR was calculated. This was a retrospective and cross-sectional study. With increasing age there is a significant increase of VBD, a slight increase of DSD, and a slight decrease of DSR. There is no significant sex difference. DSR in healthy children is higher than in healthy adults. MRI is a reliable method demonstrating the natural shape of the lumbosacral spine and its absolute values. These normal values compare well with those established by conventional radiological techniques. Our data may serve as a reference for defining dural ectasia in children with Marfan syndrome.

To evaluate the asymmetry of bilateral orbital development in Chinese children with congenital microphthalmia and to provide a criterion for tailoring treatment timing and therapy. Retrospective cohort study. By combining multisection helical computerized tomography imaging with a computer-aided design system, we measured 38 children between 0 and 6 years of age with congenital microphthalmia and 70 normal children of the same age group. Variables were measured, including orbital volume, depth, width, and height and eyeball volume. Displacement of the orbital rims was calculated by mirroring the unaffected orbit across the midsagittal plane of body. Significant differences were observed between the orbital volume, eyeball volume, orbital width, and orbital height of the affected and unaffected sides of children with congenital microphthalmia (P development is evident primarily in the inferior and lateral rims, correlating mostly with zygomatic and then maxilla and frontal bone. The growth of the affected orbit slows down or even stagnates by 3 years of age. Intervention therapy before 3 years of age was critical. Copyright © 2012 Elsevier Inc. All rights reserved.

Contrast enemas with barium or water-soluble contrast agents are sometimes performed in children with severe intractable constipation to identify anatomical abnormalities. However there are no clear definitions for normal colonic size or abnormalities such as colonic dilation or sigmoid redundancy in children. To describe characteristics of colonic anatomy on air contrast enemas in children without constipation to provide normal values for colonic size ratios in children. We performed a retrospective chart review of children aged 0-5 years who had undergone air contrast enemas for intussusception. The primary outcome measures were the ratios of the diameters and lengths of predetermined colonic segments (lengths of rectosigmoid and descending colon; diameters of rectum, sigmoid, descending colon, transverse colon and ascending colon) in relation to the L2 vertebral body width. We included 119 children (median age 2.0 years, range 0-5 years, 68% boys). Colonic segment length ratios did not change significantly with age, although the differences for the rectosigmoid/L2 ratio were borderline significant (P = 0.05). The ratios that involved the rectal and ascending colon diameters increased significantly with age, while diameter ratios involving the other colonic segments did not. Differences by gender and race were not significant. These data can be used for reference purposes in young children undergoing contrast studies of the colon.

Full Text Available The purpose of this study was to examine the level of empathy in deaf and hard of hearing (preadolescents compared to normal hearing controls and to define the influence of language and various hearing loss characteristics on the development of empathy.The study group (mean age 11.9 years consisted of 122 deaf and hard of hearing children (52 children with cochlear implants and 70 children with conventional hearing aids and 162 normal hearing children. The two groups were compared using self-reports, a parent-report and observation tasks to rate the children's level of empathy, their attendance to others' emotions, emotion recognition, and supportive behavior.Deaf and hard of hearing children reported lower levels of cognitive empathy and prosocial motivation than normal hearing children, regardless of their type of hearing device. The level of emotion recognition was equal in both groups. During observations, deaf and hard of hearing children showed more attention to the emotion evoking events but less supportive behavior compared to their normal hearing peers. Deaf and hard of hearing children attending mainstream education or using oral language show higher levels of cognitive empathy and prosocial motivation than deaf and hard of hearing children who use sign (supported language or attend special education. However, they are still outperformed by normal hearing children.Deaf and hard of hearing children, especially those in special education, show lower levels of empathy than normal hearing children, which can have consequences for initiating and maintaining relationships.

Numerous adverse factors are acting in the prenatal, perinatal and postnatal period of life and may be the cause of later mild or severe deviations from normal psychomotor development. Therefore, it is crucial to identify infants with neurological risk factors and infants that already have a delay from orderly development, in order to immediately initiate the rehabilitation process. The aim of this study was to determine whether there is difference in the assessment of psychomotor development in neurological risk children based on the psychomotor development test (Croatian, Razvoj psihomotorike, RPM test) and clinical evaluation of neuromotor development. RPM test is designed for rough estimate of psychomotor development in children in the first two years of life. The study included 15 full term children (8 male and 7 female) with clinical diagnosis of mild paraparesis and mild deviation from normal psychological and social development, and 15 full term children (8 male and 7 female) without neurological risk factors and deviations from normal psychomotor development, all at the age of 12-24 months. Of the 15 children diagnosed with mild paraparesis, none had delayed psychomotor development, 6.7% had suspect development and 93.3% had normal development on RPM test. All children in the control group had normal development on RPM test. According to the results, the RPM test is not sensitive enough to detect mild neurodevelopmental disorders.

Kenyan women adult literacy learners: why their motivation is difficult to sustain.

Kenya, like other Third World countries, has illiteracy rates for women which are twice those of men (in 1978, 35% of males and 70% of females aged 15 and above were illiterate). Since the beginning of the country's literacy campaign in 1979, women have comprised more than 70% of attendees. While this situation remains the case, the overall enrolment figures for the program have shown a gradual decline from 1979 to 1990 due to a lack of emphasis on individual motivation. Women dominate the literacy programs for several reasons: 1) women historically had less access to formal education than men; 2) the changing economy has forced women to assume extra responsibilities outside the home which make the women want to acquire formal skills; 3) women's schedules are often flexible enough to allow them to attend classes; 4) literacy classes provide women with needed socialization opportunities; and 5) in some communities cultural norms prevent men from attending classes with women. Women also have many obstacles which make their desire to become adult learners difficult to sustain. They have responsibilities which range from child-bearing to management of their family farms which leave them little time for study or class attendance. There is also little encouragement offered the women either at home or in their classes. At home they are confronted with a myriad of demands on their time. Their classes take place in conditions which are not very conducive to learning (classrooms designed for children or open air centers). The literacy teachers are, for the most part, unqualified. They must meet only minimal requirements and receive no training. The women also have less opportunities to practice their new skills outside of the classroom. Women have less time then men to read, and they are less fluent then men in English and Kiswahili, the 2 official languages of Kenya. Because Kenyan society is male-dominated, there is little encouragement given to women who attempt to

Adverse childhood experiences are a critical feature of lifelong health. No research assesses whether childhood adversities predict HIV-testing behaviors, and little research analyzes childhood adversities and later life HIV status in sub-Saharan Africa. We use regression models with cross-sectional data from a representative sample (n = 1974) to analyze whether adverse childhood experiences, separately or as cumulative exposures, predict reports of later life HIV testing and testing HIV+ among semi-rural Kenyan women and their partners. No significant correlation was observed between thirteen cumulative childhood adversities and reporting prior HIV testing for respondent or partner. Separately, childhood sexual abuse and emotional neglect predicted lower odds of reporting having previously been tested for HIV. Witnessing household violence during one's childhood predicted significantly higher odds of reporting HIV+. Sexual abuse predicted higher odds of reporting a partner tested HIV+. Preventing sexual abuse and household violence may improve HIV testing and test outcomes among Kenyan women. More research is required to understand pathways between adverse childhood experiences and partner selection within Kenya and sub-Saharan Africa, and data presented here suggest understanding pathways may help improve HIV outcomes. © The Author 2016.

Subclinical Hypothyroidism in Children: Normal Variation or Sign of a Failing Thyroid Gland?

Directory of Open Access Journals (Sweden)

Kaplowitz PaulB

2010-05-01

Full Text Available Subclinical hypothyroidism (SCH, defined by a normal total or free T4 level and a mildly elevated TSH (typically 5–10 mU/L, is common in children, but there is currently no consensus on management. Several recent pediatric studies indicate that progression of SCH to overt hypothyroidism (OH is uncommon and that over a period of several years, elevated TSH usually either normalizes or persists but does not increase. The etiology appears to be multifactorial, with some cases representing minor developmental abnormalities, some related to obesity, some to mild autoimmune thyroiditis, and some associated with mutations in the gene for the TSH-receptor. There are no pediatric studies showing clinical benefit of treating these children with thyroid hormone, but additional studies in this area are needed. Since few cases of pediatric SCH progress to OH, treatment can be deferred, and periodic follow-up testing may be the preferred strategy, with elevated thyroid antibodies or a goiter being considered risk factors for eventual OH.

Wide Ranging Insect Infestation of the Pioneer Mangrove Sonneratia alba by Two Insect Species along the Kenyan Coast.

Full Text Available Insect infestation of mangroves currently threatens mangrove forest health and management. In the Western Indian Ocean region, little is known about insect damage to mangroves despite the fact that numerous infestations have occurred. In Kenya, infestations of Sonneratia alba have persisted for almost two decades, yet the taxonomic identity of the infesting pest(s, the extent of infestation, the pests' biology, the impacts of infestation on host and the ecosystem, the host's defensive strategies to the infestation are poorly understood. S. alba is a ubiquitous, pioneer mangrove species of the Indo-Pacific, occurring along the waterfront in a variety of mangrove ecosystem settings. Our main objectives were to identify the pest(s responsible for the current dieback of S. alba in Kenya, and to determine the extent of infestation. To identify the pests responsible for infestation, we trapped emergent insects and reared larvae in the laboratory. To determine the overall extent of infestation within the S. alba zone, we assessed nine sites along the entire Kenyan coastline for the presence or absence of infested mangroves. Insect infestation in two mangrove embayments (Gazi and Mida was quantified in depth. Two wood-boring insects were identified: a metarbelid moth (Lepidoptera, Cossoidea of undescribed genus and the beetle Bottegia rubra (Cerambycidae, Lamiinae.The metarbelid moth infests mangroves in both northern (from Ngomeni to Kiunga and southern regions (from Vanga to Mtwapa of the Kenyan coast. B. rubra appeared in low density in Gazi, and in high density in Mida, Kilifi, and Ngomeni, with densities gradually decreasing northward. Insect infestation levels reached 18% in Gazi and 25% of S. alba stands in Mida. Our results indicate that B. rubra has the ability to infest young mangrove trees and expand its range, posing a danger to rehabilitation efforts where plantations have been established. Thus, there is great need for forest managers to

We explore whether perceived stress among Kenyan mothers is predicted by childhood exposure to emotional abuse - both witnessed among parents and experienced directly. Further, we explore whether this association is mediated by social support, family functioning and polygynous marriage. We used cross-sectional data from a systematic random sample (n = 1974) of mothers in semi-rural Kenya. Data were collected using validated scales and trained interviewers. Analyses were conducted using bootstrapped structural equation models and fixed-effects linear regression models, controlling for age and household wealth. Reported experience of emotional abuse - both directly experienced and observed among household adults - was high in the present population (72.5% and 69%, respectively). Perceived stress among women was significantly higher if they were exposed to more emotional abuse during childhood (p emotional abuse exposure during childhood and adult perceived stress. Future research should investigate whether social integration, identity formation and self-esteem underlie observed dynamics in sub-Saharan Africa. Efforts to promote social integration and support should target children currently experiencing emotional abuse, and may include child-targeted high quality television programing and adult-targeted media and celebrity campaigns.

Full Text Available Brachiaria grass is an emerging forage option for livestock production in Kenya. Kenya lies within the center of diversity for Brachiaria species, thus a high genetic variation in natural populations of Brachiaria is expected. Overgrazing and clearing of natural vegetation for crop production and nonagricultural uses and climate change continue to threaten the natural biodiversity. In this study, we collected 79 Brachiaria ecotypes from different parts of Kenya and examined them for genetic variations and their relatedness with 8 commercial varieties. A total of 120 different alleles were detected by 22 markers in the 79 ecotypes. Markers were highly informative in differentiating ecotypes with average diversity and polymorphic information content of 0.623 and 0.583, respectively. Five subpopulations: International Livestock Research Institute (ILRI, Kitui, Kisii, Alupe, and Kiminini differed in sample size, number of alleles, number of private alleles, diversity index, and percentage polymorphic loci. The contribution of within‐the‐individual difference to total genetic variation of Kenyan ecotype population was 81%, and the fixation index (FST = 0.021 and number of migrant per generation (Nm = 11.58 showed low genetic differentiation among the populations. The genetic distance was highest between Alupe and Kisii populations (0.510 and the lowest between ILRI and Kiminini populations (0.307. The unweighted neighborjoining (NJ tree showed test ecotypes grouped into three major clusters: ILRI ecotypes were present in all clusters; Kisii and Alupe ecotypes and improved varieties grouped in clusters I and II; and ecotypes from Kitui and Kiminini grouped in cluster I. This study confirms higher genetic diversity in Kenyan ecotypes than eight commercial varieties (Basilisk, Humidicola, Llanero, Marandú, MG4, Mulato II, Piatá and Xaraés that represent three species and one three‐way cross‐hybrid Mulato II. There is a need for further

Information Sharing, Cooperative Behaviour and Hotel Performance: A Survey of the Kenyan Hospitality Industry

Full Text Available Information sharing is the life blood of supply chain collaboration. Its role in achieving operational performance of supply chains has been widely acclaimed. However whether information sharing would result in improved performance in the context of the hospitality industry has not been empirically determined. This study sought to find out the role of information sharing on hotel performance when the relationship was mediated by cooperative behaviour. A survey design was employed where proportionate stratified sampling was used to select 50 out of 57 town hotels. Data was collected through the use of questionnaires as well interview guides to the procurement\\supply chain departments of these hotels. Logarithmic transformations were used in conjunction with multiple regression analysis to determine the relationship between information sharing, cooperative behaviour and hotel performance. The study concludes that information sharing in the Kenyan hospitality industry does not directly relate to hotel performance. Its relationship is mediated by cooperative behaviour (trust and attitude with supply chain partners. This suggests that information sharing is essential but insufficient by itself to bring significant performance improvements in hotels in the Kenyan hospitality industry. A possible reason for this is that this collaborative practice is highly dependent on information sharing capability, structure of the information as well as culture. Through quadrant analysis the study identifies and recommends the sharing of information about long term strategic plans and events such as entering new markets and acquiring a new customer base as an area of primary priority for improvement.

Use of technetium-99m labelled mercaptoacetyltriglycine ( 99m Tc-MAG3) simplifies and improves the quantification of renal clearance in children by virtue of its permanent availability, good imaging properties and low radiation exposure. Due to the lack of reference values for 99m Tc-MAG3 clearance in children, the Paediatric Task Group of the EANM initiated a multicentre study to evaluate 99m Tc-MAG3 clearance values in children with minimal renal disease. One hundred and twenty-five children aged between 12 months and 17 years, classified as renally healthy using defined diagnostic criteria, were included in the study. 99m Tc-MAG3 clearance was calculated using an algorithm on the basis of a single blood sample taken at any time between 30 and 40 min after tracer injection. In addition, the absolute 99m -Tc-MAG3 clearance values were normalized to body surface area. For further evaluation the children were classified into several groups according to age. There was a continuous increase in non-corrected 99m Tc-MAG3 clearance values from the age of 1 year up to the age of 17 years (mean value 8 years: 208±66 ml/min). Normal clearance values for adults were achieved by the age of 8 years. Analysis of the relationship between non-corrected clearance and age yielded a correlation coefficient of r=0.7. When these absolute clearance values were normalized to body surface area, we found nearly constant clearance values for all age groups, with a mean clearance value of 315±114 ml/min x 1.73 m 2 . The correlation coefficient for the relationship between normalized clearance and age was r=0.28. In conclusion, the clearance of 99m Tc-MAG3 increases continuously throughout childhood into adolescence due to the maturation and growth of the kidney. After normalization of the absolute clearance to body surface area, no correlation between clearance and age could be proven. (orig.)

The purpose of the present study was to obtain a cutoff value of liver fat content for the diagnosis of hepatic steatosis by comparing magnetic resonance (MR) spectroscopy results in children and adolescents with normal and excess weight. The study included 420 children and adolescents (91 normal-weight, 99 overweight, and 230 obese) 8-18 years of age. Proton magnetic resonance spectroscopy was performed with a 3T MR system using point resolved spectroscopy sequence with series echo times. The mean absolute mass concentration of liver fat was obtained: 0.5 ± 0.04% in normal-weight boys; 0.5 ± 0.03% in normal-weight girls; 0.9 ± 0.16% in boys with overweight; 1.1 ± 0.24% in girls with overweight; 1.7 ± 0.24% in boys with obesity; and 1.4 ± 0.21% in girls with obesity. The cutoff value of absolute mass concentration of liver fat for hepatic steatosis was found to be 1.5%. Based on this cutoff value, hepatic steatosis was diagnosed in 16% of boys with overweight, 11% of girls with overweight, 32% of boys with obesity, and 27% of girls with obesity. Proton magnetic resonance spectroscopy was successfully applied to obtain the cutoff value of absolute mass concentration of liver fat for the diagnosis of hepatic steatosis in children and adolescents. Children and adolescents with obesity have higher risk of hepatic steatosis than their peers with overweight. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

Kenny, D J; Casas, M J; McPherson, K A

1989-01-01

Preliminary results of an investigation that synchronizes the videotaped output of ultrasound camera and the analog data from physiological measurements of swallowing and ventilation in normal and cerebral palsied (CP) children are presented. Four cerebral palsied children and three control children undertook a single sip-swallow of 5 ml of liquid and a solid mastication-swallow sequence on three occasions according to a defined protocol. The CP children exhibited much more variability and less control of the liquid bolus than did the controls. The ultrasound image clearly demonstrates the lack of control of the posterior of the tongue in many CP children. Some parts of the sequence of oral swallow and the time to achieve maximum anterior displacement of the hyoid bone appear to be slowed. The sequential events of swallowing show less variability as the sip-swallow proceeds from the oral voluntary to pharyngeal and lower involuntary phases. This study also identified a short-latency apnea that appears to accompany a saliva (protective) swallow and a long-latency apnea that accompanies semi-solid or liquid bolus (alimentary) swallows. Further investigations of normal and CP children utilizing a combined diagnostic imaging-physiological measurement approach will follow this initial study.
