    OBJECTIVE. To characterize utilization of oral hygiene devices and customs in schoolchildren. MATERIAL AND METHODS. We performed a cross-sectional study in 1,404 schoolchildren (6- 12 year olds) from 14 public schools in Pachuca, Hidalgo, México, using a questionnaire for sociodemographic variables and 1) Tooth brushing frequency (customs were 85.5% tooth brushing, 90.9% toothpaste, 19.4% flossing, and 28.2% mouthwash. Only 11.8% of participants reported utilization in all 4 categories. We observed differences (p < 0.05) across sexes only in the use of toothpaste, as women used it more often. Differences across age were observed (p < 0.05) for tooth brushing (younger children brushed more often) and flossing (older children flossed more often). CONCLUSIONS. Tooth brushing was the oral hygiene practice more often performed in this sample, with other frequencies being relatively low. There were differences by age and sex across some variables.

    Muscular hypertrophy secondary to denervation is very rare, but well-documented phenomena in adults. This is the first report of a child with neurogenic unilateral hypertrophy due to S1 radiculopathy. A 12-year-old girl presented with left calf hypertrophy and negative history of low back pain or trauma. The serum creatinine kinase level and inflammatory markers were normal. Magnetic resonance imaging showed muscle hypertrophy of the left gastrocnemius and revealed a protruded lumbar disc at the L5-S1 level. The protruded disc abuts the S1 root on the left side. Electromyography showed mild left S1 radiculopathy. Passive stretching and work load might clarify the origin of neurogenic hypertrophy but there is still a need for further evidence. Clinical, laboratory, magnetic resonance imaging and electromyography findings showed that S1 radiculopathy could be a cause of unilateral calf swelling in youth even in the absence of a history of back or leg pain.

    A 12-year-old congenitally-blind girl drew a car moving, stationary, and braking. For stationary, she put the wheels inside the car and, for braking, drew the wheels as rough rectangles. At the age verbal metaphor is understood (Winner, 1988), the girl invented metaphoric drawings. In these, what is shown is not what is meant. In late childhood, metaphor may be understood similarly in pictures and words and by the sighted and blind.

    Full Text Available The present study aims to determine the level of oral hygiene, periodontal status and treatment needs, indicating if there are differences between men and women, in 12-year-old students from Castro, Los Lagos region, during March and April of 2014. A cross-sectional study was carried out. A total of 242 12-year-old students from municipal and subsidized private schools in Castro were selected through a stratified random sample representative of each school. Students were evaluated by a calibrated examiner to determine the Simplified Oral Hygiene Index (OHI-S and the Community Periodontal Index of Treatment Needs (CPITN. Data were transferred to a Microsoft Excel spreadsheet and statistically analyzed to calculate the amount and percentage of the variables. Mann-Whitney U-test was used for comparison between genders. From the total, 59.5% of the students have regular hygiene. Also, 86.4% of the assessed adolescents have gingivitis and 13.6% of them have periodontitis. The periodontal treatment need indicates that 58% of the students require oral hygiene instructions and scaling. No statistically significant differences were found for gender. There is a higher prevalence of periodontal diseases associated with regular oral hygiene than the regional and national reference in 12-year-old adolescents in Castro. Then, it is necessary to teach and promote specific public health strategies based on epidemiological data

    Full Text Available Bezoar is a tightly packed collection of undigested material that is unable to exit the stomach. Most bezoars are of indigestible organic matter such as hair-trichobezoars; or vegetable and fruit-phytobezoars; or a combination of both. Trichobezoars commonly occur in patients with psychiatric disturbances who chew and swallow their own hair. In very rare cases, the Rapunzel syndrome hair extends through the pylorus into the small bowel causing symptom and sign of partial or complete gastric outlet obstruction. A case report of trichobezoar in the stomach causing Rapunzel syndrome in a 12-year-old female is reported.

    Undifferentiated sarcomas are rare tumors not classified into any sarcoma subtype. Due to their rarity, imaging findings of undifferentiated sarcomas are poorly characterized. The purpose of this report was to present imaging findings of a pathologically confirmed undifferentiated sarcoma originated from the left kidney of a 12-year-old boy. The mass was infiltrative involving the renal pelvis. It mimicked massive hilar lymphadenopathy with a preserved renal contour visible by both ultrasonography and CT. Renal vein thrombosis was also observed. Although undifferentiated sarcomas are rare, they should be considered in differential diagnosis of infiltrative renal masses with renal pelvis invasion in children.

    The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. Four hundred sixty-three Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordinationstest für Kinder (KTK) and two Athletic Skills Tracks (AST-1, AST-2). The validity of AST-1 and AST-2 was examined by correlating the time (s) needed to complete the tracks and the KTK Motor Quotient (MQ). Overall, there was a low correlation between AST-1 and the KTK MQ (r = -0.474 (P year-olds. The results indicate that fundamental movement skills of 6- to 12-year-old children can be assessed with a quick, convenient and low-cost motor competence test in a physical education setting, i.e., an Athletic Skills Track. Future studies should further assess the reliability, discriminative ability and validity of age-specific versions of the AST.

    We sought to determine the prevalence of interictal epileptiform discharges (IEDs) in healthy 11- and 12-year-old children. Sixth grade students with no history of seizure, or neurologic or psychiatric disease, were enrolled in a longitudinal physical activity intervention study. Per study protocol, each student had two EEG recordings approximately 6months apart. Epileptiform discharges were present in 4 (2.9%) of 140 students: centrotemporal in three and generalized in one. In three children, the discharges were still present six months later. None of the children had developed seizures a minimum of one year after the second EEG. These results are consistent with those of two landmark European studies performed nearly a half century ago, before the modern era of digital EEG. Healthy 11- and 12-year-old children with no history of seizure may have centrotemporal or generalized epileptiform discharges on EEG, which can persist for at least 6months. Based on both our results and those of the two prior European studies, such discharges, if found incidentally in otherwise healthy children in this age group, should not prompt further evaluation or treatment.

    Full Text Available Background and Aim: Extensive studies on the epidemiology of teeth and oral diseases are an important part of health care programs specially for hearing impaired groups. For adequate programming in this field, proper situation analysis is mandatory. The aim of this study was to assess the DMFT (decayed missed filled teeth of 12 years old students attending hearing impaired schools in Tehran and exploring the relation between sex, hygiene and hearing threshold with the index. Materials and Methods: This cross sectional descriptive study was based on examining 12 years old (± 6 month students (117 cases attending hearing impaired schools in Tehran. A questionnaire was filled for each case. T, Chi-square and Kruskall-Wallis tests were used to analyze the results with p<0.05 as the limit of significance. Results: The mean DMFT in these students was 3.07. Mean DMFT in students with very severe hearing loss was 2.99. Mean ranked DMFT in girls and boys was similar (56.09 in boys and 61.96 in girls. Mean ranked DMFT in students who didn’t use floss (66.40 was higher than those who used floss (46.71. Mean ranked DMFT in students who seldom brushed, was the highest (72.82 and in students who brushed once a day was the lowest (51.26. Conclusion: The DMFT index in hearing disabled children was 3.07. Regular brushing and flossing reduced the index.

    Full Text Available The last two decades a huge progress has taken place in the field of the primary prevention of infections and many new vaccines have been introduced in the compulsory vaccination program. There is evidence, however, that immunization coverage against some infectious diseases is not adequate. Aim: It was to investigate the level of immunization coverage of Greek and Immigrants' children aged 4-12 years old in the prefecture of Evritania regarding vaccines against pertussis-diphtheria-tetanus (DTaP, poliomyelitis (IPV and measles–mumps–rubella (MMR. Material and methods: The sample of the study consisted of the pupils of all nursing and elementary schools of the prefecture of Evritania , aged 4-12 years old. Children's personal Health Cards were used to evaluate the adequacy of vaccine doses. X2 was usedfor comparisons. Statistics was processed with SPPS 17.0. Results: The boys of the sample were 469 (51.9% and the girls 434 (48.1%. Full vaccination coverage with DTaP, MMR and IPV was 87.3%, 79.9%, and 97.6% respectively. No statistically significant differences were observed between Greek and Immigrants' children. Conclusion: Vaccination coverage against measles, mumps and rubella was inadequate. Immigrants' and Greek children are equally covered. Vaccination coverage with MMR is troublesome.

    Early-onset bipolar disorder has significant morbidity and mortality. Development of safe, effective treatments to which patients will adhere is critical. Pharmacologic interventions for childhood bipolar spectrum disorders are limited and are associated with significant risk for adverse events. Diet and nutrition research suggests vitamins, minerals, and other nutrients are important underpinnings of general physical and mental health; furthermore, they may even be useful in treating mood dysregulation by providing a more favorable risk-benefit ratio than contemporary psychotropic agents. This article reviews the literature on multinutrient supplementation and mental health, and examines a case study of a 12-year-old boy with bipolar disorder and co-morbid diagnoses treated for 6 years with conventional medication and finally a multinutrient supplement. The multinutrient supplement in this case study is EMPowerplus (EMP+), a 36-ingredient supplement containing 16 minerals, 14 vitamins, 3 amino acids, and 3 antioxidants. It was used to treat a 12-year-old boy initially diagnosed with bipolar disorder not otherwise specified (BP-NOS) at age 6, and whose diagnosis evolved by age 10 to bipolar I (BP-I), mixed, with psychotic features. He also met criteria for generalized anxiety disorder by age 8 and obsessive-compulsive disorder by age 10. After 6 years of conventional treatment (ages 6-12), he received 14 months of EMP+. Symptom manifestation over 7 years is described in conjunction with treatment history. EMP+ resulted in outcome superior to conventional treatment. This report adds to accumulating preliminary evidence that further basic science and clinical studies of multinutrient supplements are warranted.

    Full Text Available Despite advances in imaging and antibiotic treatment, brain abscess is still encountered occasionally. Various aerobic and anaerobic bacteria have been reported as causative agents of brain abscess but only a few cases of enterococcal brain abscesses have been reported. Here we report a case of brain abscess in a 12-year-old female patient, who presented with a history of fever, chills, headache, convulsions since seven days and history of altered sensorium and aphasia since the last two days . The patient had chronic suppurative otitis media of both ears following trauma and presented with ear discharge. The diagnosis of brain abscess was done by computerized tomography scan and the pus was aspirated by left suboccipital burr hole operation. Enterococcus species was cultured from the aspirated pus sample. The patient responded to surgical drainage and antibiotic treatment.

    2008-08-01

    Annular lichenoid dermatitis of youth was first described by Annessi et al. in 2003. Clinical criteria are persistent erythematous macules and annular lesions with a red-brown edge and a central hypopigmentation usually found on the flanks and groins of children and adolescents. Histologically, the disease is characterized by a lichenoid interface dermatitis with necrotic keratinocytes at the tip of the rete ridges. In our case a 12-year old girl developed annular red-brown macules with papules at the borders in an inframammary location. The histology of the lesion's border showed a lichenoid lymphocytic infiltrate with apoptotic keratinocytes at the tip of rete ridges. The lesions cleared with 0.03% tacrolimus ointment. Annular lichenoid dermatitis of youth is probably a new entity in the group of lichenoid dermatoses.

    Full Text Available Background: Bloom′s syndrome, an autosomal recessive inherited disorder, belongs to the group of chromosomal breakage syndromes. The clinical diagnosis of BS is confirmed cytogenetically. Its frequency in the general population is unknown but it is common in eastern European Ashkenazi Jews . Case Report: A 12-year-old girl was referred to us because of short stature. She was the second child of the first cousin marriage. She had a slender body frame, short stature, and microcephaly. Her face was long and narrow with prominent nose, and malar and mandibular hypoplasia. The spots of hyper and hypo pigmentation were observed in the trunk and limbs. Telangectasia spots were observed in some areas of the trunk. Additionally, generalized hirsutism was present in the whole body. Cytogenetic findings revealed an abnormality in the structural chromosome. Conclusion: This is the first BS case that has been reported in Iranian female population.

    Full Text Available Introduction & Objective: DMFT Index is the best epidemiologic caries index in dentistry and can show the state of oral and dental hygiene in one society. By considering this index we can design suitable preventive and treatment program for total population of a society. The aim of this descriptive analytical study was evaluation of DMF6 index in 12 years old children in Hamadan city.Materials & Methods: Using explorer and mirror under natural light, 4 permanent first molars of 480 twelve years old students were examined from the aspect of decay, missing and filling; then DMF6 was accounted for each subject. The statistical analysis was done by SPSS 12 and Pearson, Chi- square test. Results: The mean of DMF6 was 2.17±1.39. DMF6 in girls (2.22 was more than boys (2.12 but this difference was not statistically significant. 72.9% of girls and 72.5% of boys had carries in their first permanent molars. 1.3% of girls and 2.5% of boys had one missing first molar. The difference between girls and boys in missing and decayed teeth was not statistically significant. 22.5% of girls and 11.7% of boys had filling teeth and only this difference was statistically significant. 26% of population had no sound teeth and only 18.8% of them had 4 sound first permanent molors. 72.7% of population had caries and 1.9% had missing and 17.1% had filled teeth. Conclusion: Analysis of DMF6 showed that untreated caries is the most important problem in 12 years old children in Hamadan.

    Full Text Available Background and Objectives: The group of 6-12 year-old students are the main target of oral health programs due to the high prevalence of dental caries and the formation of permanent teeth during this age and the lifestyle-shaping nature of the period. Schools provide the easiest and most effective means of accessing this group. The present study was conducted to examine the impact of school-based interventions on improved oral health in 6-12 year-old students. Materials and Methods: The present systematic review searched for its English and Persian keywords in databases such as the Scopus, Proquest, Science Direct, Pubmed, Springer, Biomed Central, Google Scholar, IranMedex and SID and examined studies published between January 2004 and September 2014 about educational interventions aiming to prevent oral diseases and promote associated health behaviors in students. Results: The 17 studies selected for examination were divided into two categories: first, assessing an education based on self-care behaviors and preventive services second, assessing an education based on self-care behaviors only. Those interventions that were consistent in nature, involved the parents and the school personnel, used behavior change models, used a combination of several training methods, used practical experiences and provided preventive services were more effective in promoting knowledge and health behaviors and reducing dental caries and plaque in this group of children. Conclusion: Providing consistent community-based education, using a combination of several organized educational programs, following up on the children's progress, using behavior change theories and models and providing prevention services are the most effective measures for achieving the desired goals.

    Full Text Available "nThe aim of the present study was to determine the effects of adenotonsillectomy on height, weight and body mass index (BMI in children under 12 years old, with or without airway obstruction and evaluation of the risk of overweight in them. In this case-control study, 120 children with the age of 2-12 years old were studied; 60 children as case group who underwent adenotonsillectomy and 60 healthy children as control group. After collecting the data related to appetite status and sleep breathing disorder of the case group, height, weight and BMI have been measured for all children in two stages; preoperatively and 6 months later. Also in the case group, BMI percentiles, pre and postoperatively have been calculated. Patients with Low appetite in the initiation and at the end of the study in the case group were 80% and 8.3% respectively (P=0.01. Mean of height, weight and BMI variation after 6 months were significantly different between case and control groups (P<0.05. BMI percentiles in the case group preoperatively were: 20% underweight, 67% healthy weight, 10% at risk of over weight, 3% over weight. Postoperatively, after 6 months BMI percentiles in order of above frequency were: 10%, 57%, 22% and 11% (P=0.02. Analysis of the results showed that adenotonsillectomy can lead to increase of height, weight, BMI and appetite not only in the children with low weight due to airway obstruction but also in the normal weight and over weight children. Therefore risk of overweight should be mentioned as a probable undesirable outcome of adenotonsillectomy.

    Background. Fracture resulting from household electric shock is uncommon. When it occurs, it is usually the result of a fall; however, electricity itself can cause sufficient tetany to produce a fracture. We present the case of bilateral fractures of the distal radii of a 12-year-old boy which were sustained after accidental shock. The literature regarding fractures after domestic electric shock is also reviewed. Methods. An Ovid-Medline search was conducted. The resultant articles and their bibliographies were surveyed for cases describing fractures resulting from a typical household-level voltage (110-220 V, 50-60 Hertz) and not a fall after the shock. Twenty-one articles describing 22 patients were identified. Results. Twenty-two cases were identified. Thirteen were unilateral injuries; 9 were bilateral. Proximal humerus fractures were most frequent (8 cases), followed by scapula fractures (7 cases), forearm fractures (4 cases), femoral neck fractures (2 cases), and vertebral body fracture (1 case). Eight of the 22 cases were diagnosed days to weeks after the injury. Conclusions. Fracture after electric shock is uncommon. It should be suspected in patients with persistent pain, particularly in the shoulder or forearm area. Distal radius fractures that occur during electrocution are likely due to tetany.

    Full Text Available Calcinosis cutis is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin in various parts of the body. Four main types of calcinosis cutis have been recognized according to etiology: associated with localized or widespread tissue changes or damage (dystrophic calcification, that associated with an abnormal calcium and phosphorus metabolism (metastatic calcification, not associated with any tissue damage or demonstrable metabolic disorder (idiopathic calcification, and Iatrogenic. Very few cases of idiopathic calcinosis cutis are reported in early childhood in the literature. We report one such case of idiopathic calcinosis cutis over elbow in a 12-year-old female child. Histological examinations of the lesions resected in this case reveal calcium deposits in the dermis, surrounded by foreign body giant cells. Idiopathic calcinosis cutis is a rare phenomenon and occurs in the absence of known tissue injury or systemic metabolic defect. It is important to delineate it from other calcification disorders for further plan of management. Medical therapy in calcinosis cutis is of limited benefit in pediatric age group and poses a challenging problem of postsurgical management.

    Expectations prior to needle-related procedures can influence individuals' decision making and compliance with immunization programmes. To protect from human papilloma virus (HPV) and cervical cancer, the immunization needs to be given before sexual debut raising interest for this study's aim to investigate how 11 to 12-year-old girls narrate about their expectations prior to HPV vaccination. A total of 27 girls aged 11 to 12 years participated in this qualitative narrative study by writing short narratives describing their expectations. The requirement for inclusion was to have accepted HPV vaccination. Data were subjected to qualitative content analysis. Findings showed the following expectations: going to hurt, going to be scared and going to turn out fine. The expectations were based on the girls' previous experiences, knowledge and self-image. The latent content revealed that the girls tried to transform uneasiness to confidence. The conclusion drawn from this study is that most girls of this age seem confident about their ability to cope with possible unpleasantness related to vaccinations. However, nurses need to find strategies to help those children who feel uneasy about needle-related procedures.

    Full Text Available Idiopathic central serous chorioretinopathy (CSC typically affects middle-aged males. To date, only one case of idiopathic CSC in a prepubertal subject has been reported. Atypical idiopathic CSC presentation may be challenging to diagnose. Exclusion of secondary causes of serous retinal detachment (SRD is warranted. We describe the atypical case of a 12-year-old female with a circumscribed SRD that resolved spontaneously and with fluorescein angiography (FA findings that were compatible with idiopathic CSC. Optical coherence tomography (OCT and systemic assessment were performed to exclude other etiologies. FA demonstrated multiple focal leaks in early phases, with subretinal leakage and pooling in late phases. OCT showed a localized circumscribed retinal detachment. Complete blood count was within normal limits. Serum cortisol was normal (22.1 µg/dl and mean arterial blood pressure was 100/60 mm Hg, thereby excluding secondary causes of CSC. This is the second reported case of idiopathic CSC in a prepubertal female and the first one documented by FA and OCT, as well as other studies to exclude secondary causes. Albeit rare, idiopathic CSC should be considered in the differential diagnosis of SRD in this (prepubertal age group, after excluding secondary ocular or systemic etiologies.

    The aim of this study was to describe malocclusion prevalence and its association with individual and contextual factors among Brazilian 12-year-old schoolchildren. This cross-sectional study included data from an oral health survey carried out in Goiânia, Brazil (n = 2,075), and data from the files of the local health authority. The data were collected through oral clinical examinations. The Dental Aesthetic Index (DAI) was used to assess occlusion. The presence of malocclusion (DAI > 25) was used as the dependent variable. The individual independent variables consisted of adolescents' sex and race and their mothers' level of schooling. The clinical variables were caries experience and presence of adverse periodontal condition (calculus and/or gingival bleeding). The contextual variables included type of school and the location of schools in the city's health districts. The Rao-Scott test and multilevel logistic regression were performed. The prevalence of malocclusion was 40.1%. In the final model, significantly higher rates of malocclusion were found among those who attended schools located in less affluent health districts and whose mothers had fewer years of education. Rates were also higher among those presenting calculus and/or gingival bleeding. Malocclusion demonstrated a high prevalence rate and the inequalities in its distribution were determined by individual and contextual factors.

    The aim of this ecological study was to analyze to what extent World Health Organization goals were met in relation to dental caries in 2000 in Minas Gerais State, Brazil, identifying factors associated with variation in DMFT and the occurrence of DMFT < or = 3 among 12-year-old children and in the percentage of caries-free 5-year-olds. Secondary data from different sources were used. Linear regression and multiple logistic regression techniques were applied to the analysis of the numerical and dichotomous dependent variables. Socioeconomic and dental services supply/utilization indicators were used as potential explanatory variables. The goals expressed by DMFT < or = 3 at 12 years and a minimum of 50% caries-free 5-year-olds were met by 37% and 9% of the State's municipalities, respectively. In general the dependent variables were associated with socioeconomic level, and no associations were identified with dental care. The results should not be generalized, but they do suggest inequities in oral health and the role played by socioeconomic factors and water fluoridation.

    Full Text Available Introduction Tachycardia-induced cardiomyopathy (TIC is a ventricular dysfunction secondary to chronic and persistent tachycardia that can regress partially or completely following heart rate normalization. Paroxysmal atrial tachycardia and permanent junctional reciprocating tachycardia are two types of frequent arrhythmias that can cause cardiomyopathy in children. Case Presentation A 12-year-old child with obesity (body mass index > 26.8 was admitted with fatigue, pallor and tachypnea to the clinic. He had palpitation for the past 24 hours. On the cardiac auscultation, holosystolic 2/6 murmur was heard in the apex as well as gallop rhythm. Electrocardiogram revealed heart rate of 150 - 160 bpm and negative P waves in II, III and AVF leads. The echocardiography revealed dilated cardiomyopathy with an ejection fraction of 30%. Conclusions Diagnosis of tachycardia-induced cardiomyopathy in children is important, since appropriate treatment improves the prognosis. Every child with recurrent and persistent palpitation with the first episode of congestive heart failure should be evaluated for tachycardia- induced cardiomyopathy.

    Full Text Available Abstract Background There is great interest in appropriate phenotypes that serve as indicator of genetically transmitted frontal (dysfunction, such as ADHD. Here we investigate the ability to deal with response conflict, and we ask to what extent performance variation on response interference tasks is caused by genetic variation. We tested a large sample of 12-year old monozygotic and dizygotic twins on two well-known and closely related response interference tasks; the color Stroop task and the Eriksen flanker task. Using structural equation modelling we assessed the heritability of several performance indices derived from those tasks. Results In the Stroop task we found high heritabilities of overall reaction time and – more important – Stroop interference (h2 = nearly 50 %. In contrast, we found little evidence of heritability on flanker performance. For both tasks no effects of sex on performance variation were found. Conclusions These results suggest that normal variation in Stroop performance is influenced by underlying genetic variation. Given that Stroop performance is often hampered not only in people suffering from frontal dysfunction, but also in their unaffected relatives, we conclude that this variable may constitute a suitable endophenotype for future genetic studies. We discuss several reasons for the absence of genetic effects on the flanker task.

    Full Text Available Background: Fluoride increases tooth resistance to dental caries, but mild toxicity due to excessive ingestion of fluoride can cause dental fluorosis. Drinking water naturally contains fluoride and is a major source of fluoride. In Bushehr port, drinking water is supplied from limestone springs with normal fluoride levels but dental fluorosis is observed. Methods: A total of 95 native school children (between the ages of 10-12 years old were randomly selected from four Bushehr port regions. Dental fluorosis, height and weight were examined. Probable attributing factors of dental fluorosis were also questioned. A 16 to 18 hours urinary fluoride concentration was measured with a fluoride ion selective electrode. Results: Dental fluorosis in four upper incisors was apparent in 52.6 % of the subjects. The urinary fluoride concentration was 2.18 mg/lit. Fluoride concentration in drinking water of schools ranged from 0.41 to 0.58 mg/lit. Forty percent of subjects were caries free. Conclusion: In spite of the normal range of fluoride concentration in the drinking water of Bushehr, dental fluorosis and urinary fluoride concentration are higher than the recommended ranges. Therefore, it is necessary to further investigate the amount and effects of fluoride ingestion in residents of Bushehr province.

    Full Text Available Background The causes of obesity in children are multifactorial, including genetics, physiology, metabolism, psychology, socioeconomic status, lifestyle, and culture. Objective To assess for relationships between obesity in 6 to 12-year-old children and maternal nutritional status, maternal education, eating breakfast, eating fast food, physical activity, TV watching, and playing video games. Methods This case-control study included students of Sejahtera Public School aged 6 to 12 years. Questionnaires were distributed to their parents for data on maternal education, eating breakfast, eating fast food, physical activity, TV watching and playing video games. Maternal nutritional status was assessed by one of the researchers. Univariate analysis with Chi–square test was used to assess every risk factor. Those with a P value of <0.25 were subjected to multivariate analysis, performed using multiple logistic regression analysis. Results From June to July 2013, 60 obese children and 60 well-nourished children, as a control group, were enrolled in the study. Obese mothers tended to have obese children [odds ratio/OR 252.48; 95%CI 33.4 to 1908.4]. Children who ate fast food 6–8 times/week, had low physical activity, and watched TV more than 8 hours/week had significantly higher risk for obesity [OR 12.94, 95%CI 1.7 to 100.7; and OR 266.94, 95% CI 7.8 to 9137.7; OR 21.44, 95%CI 2.68 to 171.61; respectively]. Maternal education, eating breakfast, and playing video games were not significant risk factors for childhood obesity. Conclusion Maternal obesity, eating fast food 6-8 times per week, low physical activity and watching TV more than 8 hours/week are risk factors for childhood obesity.

    The neighbouring cantons Basel-Stadt and Basel-Landschaft had introduced different fluoridation schemes for caries prevention: Basel-Stadt provided drinking water fluoridated at 0.8-1 ppm F since 1962, while Basel-Landschaft introduced fluoridated domestic salt (250 ppm F since 1983). Representative samples of 12-year-old schoolchildren (6th-graders) were studied to evaluate the prevalence of (I) dental fluorosis (FOP) using the Thylstrup-Fejerskov (TF) index, (II) non fluoride-associated enamel opacities (non-FOP), and (III) hypoplasia of the incisors. Standardised frontal colour photographs were taken and assessed by four examiners after projection. Of 373 schoolchildren studied in 1999 in Basel-Stadt 119 (31.9%) showed fluoride-associated enamel opacities, i. e. 66 (17.7%) a very mild form (TF score 1), 47 (12.6%) a mild form (TF score 2), five scored TF3 and one TF5. In addition, non-FOP were diagnosed in 115 (30.8%) and hypoplasia in 47 (12.6%) children. Among the 448 children evaluated in 2001 in Basel-Landschaft 143 (31.9%) showed FOP, namely 74 (16.5%) scored TF1, 54 (12.2%) scored TF2, 12 (2.7%) scored TF3, and three (0.7%) scored TF5. Non-FOP were found among 93 (20.8%) and hypoplasia among 56 (12.5%) children. Thus, in spite of different fluoridation schemes in the two cantons, the prevalences of FOP were identical. Most fluoride-associated enamel opacities were mild or very mild. They did not represent an aesthetic problem and certainly not a public health concern.

    Full Text Available Introduction: Caries is a factor of teeth missing and its prevalence and also its expenditure are very light in Iran. Treatment ways need a lot of time, but they have little success, so it is important to prevent caries. Now if we want to have a successful model, having person's statistics is important and useful for our Research purposes. This research was done to detect caries free prevalence in students twelve year of age in Izeh city and it contained 2groups of girls and boys. It was done to indicate the connection between caries free prevalence and individual oral hygiene with brushing times, numbers during 24 hours. Methods: This research is a kind of epidemiological and descriptive study. It was done in Izeh city in 78-79 educational years. Its only document, was selection the 12 years old students. Informations collected by clinical inspections and interrogatory J method Sample volume was 400 students according to this formula N=Z2(1-p/ d2. We use Chi-square statistics test and also its soft disk (SPSS or statitistics program was about social science. Conclusion: Caries free prevalence within the whole sample was 16.5%and it was 17.5% within the girls and 15-5% within boys. According to brushing times numbers, 25% brushed once a day, 47% brushed twice and 5.5% brushed three time a day and 22.5% never brushed their teeth. Discussin and conclusion: According to the obtained dates, caries prevalence related to sex difference was meaningless and they had no connection with each other there was a meaningful connection between brushing times, numbers and oral hygiene situation which caries free developed by increasing anyone of them.

    Full Text Available Background The causes of obesity in children are multifactorial, including genetics, physiology, metabolism, psychology, socioeconomic status, lifestyle, and culture. Objective To assess for relationships between obesity in 6 to 12-year-old children and maternal nutritional status, maternal education, eating breakfast, eating fast food, physical activity, TV watching, and playing video games. Methods This case-control study included students of Sejahtera Public School aged 6 to 12 years. Questionnaires were distributed to their parents for data on maternal education, eating breakfast, eating fast food, physical activity, TV watching and playing video games. Maternal nutritional status was assessed by one of the researchers. Univariate analysis with Chi–square test was used to assess every risk factor. Those with a P value of <0.25 were subjected to multivariate analysis, performed using multiple logistic regression analysis. Results From June to July 2013, 60 obese children and 60 wellnourished children, as a control group, were enrolled in the study. Obese mothers tended to have obese children [odds ratio/OR 252.48; 95%CI 33.4 to 1908.4]. Children who ate fast food 6–8 times/week, had low physical activity, and watched TV more than 8 hours/week had significantly higher risk for obesity [OR 12.94, 95%CI 1.7 to 100.7; and OR 266.94, 95% CI 7.8 to 9137.7; OR 21.44, 95%CI 2.68 to 171.61; respectively]. Maternal education, eating breakfast, and playing video games were not significant risk factors for childhood obesity. Conclusion Maternal obesity, eating fast food 6-8 times per week, low physical activity and watching TV more than 8 hours/ week are risk factors for childhood obesity.

    ABSTRACT Background: A malocclusion is an irregularity of the teeth or a malrelationship of the dental arches beyond the range of what is accepted as normal. Objectives: To determine the prevalence of malocclusion in children aged 10-12 years in Kozhikode district of Kerala, South India. Materials and methods: A descriptive cross-sectional study was conducted among schoolchildren aged 10-12 years in six schools in Kozhikode district of Kerala, South India. A total of 2,366 children satisfied the inclusion criteria. Occlusal characteristics like crossbite, open bite, deep bite, protrusion of teeth, midline deviations, midline diastema and tooth rotation were recorded. The data were tabulated and analyzed using Chi-square test. Results: The results revealed that the overall prevalence of malocclusion was 83.3%. Of this, 69.8% of the children had Angle’s class I malocclusion, 9.3% had class II malocclusion (division 1 = 8.85%, division 2 = 0.5%) and 4.1% had class III malocclusion; 23.2% showed an increased overjet (>3 mm), 0.4% reverse overjet, 35.6% increased overbite (>3 mm), 0.29% open bite, 7.2% crossbite with 4.6% crossbite of complete anterior teeth, 63.3% deviation of midline, 0.76% midline diastema and 3.25% rotated tooth. No significant differences in gender distributions of malocclusions were noted except for increased overjet and overbite. Conclusion: There is high prevalence of malocclusion among schoolchildren in Kozhikode district of Kerala. Early interception and early correction of these malocclusions will eliminate the potential irregularities and malpositions in the developing dentofacial complex.

    Full Text Available Background: Oral and dental health are among the most important aspects of individual health. Thus, it is necessary to determine community’s oral health status. Various epidemiological studies are required at different levels to assess the efficacy of preventive, oral and dental health control programs in a society. Complications such as nutritional adverse effects, periodontal diseases and adverse psychological effects of dental caries and etc. could be prevented by in-time diagnosis and treatment. This study aimed to assess DMF, dmf index and periodontal status in 6-12 year-old students in Kermanshah City in 2009. Material and Methods: This was a descriptive cross-sectional study. Data were collected through interview and dental clinical examination using disposable dental explorer, dental mirror, periodontal probe, a flash light and a marker. Data were entered into a questionnaire containing demographic characteristics and oral and dental health status of subjects (WHO oral health assessments form. A total of 1050 students aged 6 to 12 years were evaluated for their oral health status in Kermanshah City. Data were analyzed using SPSS version 14 software. T-test and chi square test were also used for analysis. Results: A total of 50% of boys and 52% of girls were susceptible to dent facial problems due to caries, extraction, premature loss of deciduous teeth, and congenital or acquired maxillofacial problems following conditions like mouth breathing due to adenoid and etc. Overall, 18.3% of 6 year old students were caries free. Among middle school students, DMFT was 1.65±1.82 and 3.88±2.72 among female and male 12 year old students, respectively. In general, 19.8% of elementary and 16.8% of 12 year old students had clinically healthy gingiva 21.6% of 6 to 12 year old students did not brush their teeth. A significant correlation was found between the frequency of tooth brushing per day and mean dmft, mean DMFT and gingival health (P<0

    The objective of this work was to assess the quality of life of children aged 6 to 12 years old. The authors present the different conceptual and operational steps which lead to the construction of a prototype tool. It was a generic tool composed of 63 items which covered the classically described areas of life. Its originality was due to the method of construction used which included children's involvement, to the pictorial representation of real-life situations for children, and to its adaptation for gender. The evaluation of this tool showed a good level of acceptability but statistical analysis revealed some metrological inadequacies leading to the reconsideration of the initial concepts and their methods of exploration. Therefore a new tool was constructed whose validation is presented in a second article in the next issue.

    The aim of this study was to assess the prevalence, extent, severity, intraoral distribution and risk indicators for erosive tooth wear (ETW) among 12-year-old schoolchildren from Montevideo, Uruguay. A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was detected in 4.4% of schoolchildren. The overall prevalence of ETW differed significantly between categories of gender and socioeconomic status, but only between gender in the severe ETW analysis. The overall extent of ETW was significantly different between categories of gender, socioeconomic status, and swish before swallow. The extent of severe ETW differed between categories of swish before swallow and brushing frequency. In the logistic regression analysis, no association was found between the studied variables and the overall prevalence of ETW. Males were more likely to have severe ETW than females (OR = 3.22, 95% CI = 1.50-6.89). ETW may be considered a public health problem among 12-year-old-Uruguayan schoolchildren.

    Full Text Available Background: The 12 years-old children population is worldwide taken as a reference age to compare the buccal health condition of different countries, by means of various indicators that measure the presence of the main buccal diseases. The knowledge of these epidemiological profiles generates information to guide the services planning policies of the Primary Health Care. Objective: To characterize 12 years-old population's buccal health condition. Methods: Cross- sectional descriptive correlative study with a stratified probabilistic sample of 90 children starting from a universe conformed by the 269 adolescents that constitute the total of the 12 years old population of the Health Care Area VIII in Cienfuegos municipality. Pearson’s chi-square and Mantel-Haenszel lineal tendency tests were used with the determination of the relative risk and reliance intervals of 95%. Results: The decay prevalence reached 54, 4%. The COP-D index was 2, 45 being the decayed component the major percentage with 4.6%. The periodontal disease was more frequent in boys than in girls, with 54, 9% and 30, 8% respectively. 80,9% of the segments is healthy. In those affected, the calculation prevailed in 11,7%. It was determined that faulty obturations, inheritance and faulty buccal hygiene were the most affecting risk factors for children with decays, while in the periodontal disease it was faulty buccal hygiene. Malocclusions presented a prevalence rate of 40%. Out of which, 55,6% required secondary level attention. Those with habits present a risk 2 times superior of making sick. The sick epidemiological category was present in 77,8% of the total. Conclusions: We emphasize the prevention need as core issue of the primary medical care in the world today; being the General-Integral Dentist a transforming agent that according to his/her formation is capable to assume the existent health problem and to modify it positively, acting from the earliest ages.

    Oral Submucous Fibrosis (OSMF) is a chronic debilitating, potentially malignant disorder of the oral cavity. It is characterized by restricted mouth opening which results due to abnormal accumulation of collagen in the sub-epithelial layers leading to dense fibrous bands in the mouth. The pathogenesis of the disease is believed to be multifactorial. However, literature reports suggest a strong association of OSMF and arecanut chewing habit. The present paper presents a case of OSMF in a 12-year-old boy without arecanut chewing habit, but with a heavy practice of chewing tamarind seeds.

    A vesicovaginal fistula with vagina obstruction associated with vaginal calculi is an extremely rare medical condition. We report a giant primary vaginal calculus resulting from vesicovaginal fistula with partial vaginal outlet obstruction secondary to perineum trauma and surgery in a 12-year-old girl. Episiotomy was performed and the adhesive labia minora was split. After the removal of a giant calculus in the vagina, approximately 8 cm in diameter, the fistula tract was completely excised, followed by the repair of the vesicovagina fistula and the vagina. The patient was symptom-free at 6-month follow-up examination.

    Introduction. The aims of this qualitative study were to explore (a) the factors influencing mothers' decisions to vaccinate 11- to 12-year-old daughters against human papillomavirus (HPV) and (b) the mothers' and daughters' perspectives about HPV vaccine-related decision making. Methods. Participants were girls (N = 33) who had received an HPV vaccine and their mothers (N = 32), recruited from suburban and urban pediatric practices. Semistructured interviews were conducted with girls and mothers separately, and data were analyzed using framework analysis. Results. The primary factors influencing mothers' decisions to vaccinate daughters against HPV were (a) mother's beliefs and experiences; (b) interactions with clinicians, friends, and family members; and (c) exposure to media reports/marketing. Most daughters believed the decision to be vaccinated was a mutual one, although most mothers believed the decision was theirs. Conclusions. This study provides novel insights into perspectives on decision making about HPV vaccination among mothers and 11- to12-year-old daughters, which can be used in interventions to improve vaccination rates.

    Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft-tissue sarcoma that usually presents in young adults as a painless, slow-growing mass. Evans first described LGFMS in 1987 as a spindle-cell sarcoma with bland histological features and paradoxically aggressive behavior. Although young adults are most frequently affected, recent reports describe pediatric cases being increasingly more common. Males and females are affected approximately equally and common locations include the deep soft tissue of the lower extremity, particularly the thigh and trunk. Primary occurrence within the chest cavity is exceedingly rare. Local recurrence and metastasis are not uncommon and present the clinician and radiologist with challenges regarding follow-up recommendations. Review of the literature reveals many cases of slowly progressive symptoms related to a mass effect. We present a healthy 12-year-old African-American girl who interestingly developed acute symptoms of shortness of breath and chest pain while playing with her brother. (orig.)

    Stroke is a well-known complication of sickle cell disease (SCD). It is estimated to occur in approximately 11% of patients with SCD by the age of 20. The most frequent cause of cerebrovascular accident (CVA) is blockage of the intracranial internal carotid and middle cerebral arteries. Hemorrhagic stroke is less common, occurring in approximately 3% of children by age 20. Transcranial Doppler (TCD) is the standard test for prediction of stroke risk in children with sickle cell anemia. The authors present a case of a 12-year-old female with SCD transferred to their institution after suffering a catastrophic intracranial hemorrhage. Her most recent TCD was normal 6 months prior to her admission.

    Cholesterol granulomas are benign granulomatous lesions caused by tissue reaction to a foreign body such as cholesterol crystals. These crystals have been are associated with pathological conditions of pneumatized spaces, including those causing inadequate aeration, obstruction of drainage, and hemorrhage in pneumatized spaces, and where materials trapping materials, such as hemosiderin or cholesterol become trapped, and then forming a cholesterol granuloma. Cholesterol granulomas are frequently found in the temporal bones, with the middle ear, mastoid caverna, and petrous apex being the most commonly affected sites. As there have been few reported cases of cholesterol granulomas presenting as a mass in the external acoustic canal (EAC), a cholesterol granuloma occluding the entire EAC in a pediatric patient is considered quite rare. We encountered a large cholesterol granuloma occupying the entire EAC, resulting in total EAC occlusion in a 12-year-old girl. The granuloma was diagnosed via medical imaging and surgically excised.

    Full Text Available Introduction and objective: Tooth caries is the most prevalent infectious disease in children. The purpose of this study was to assess carries experience indexes and related factors among 7-12 year-old school children in Yasuj, Iran, in 2014. Materials and methods: In the present Cross-sectional and analytical study, using a two-stage random sampling, 460 students from primary schools of Yasuj city and surrounding villages were selected. The children were clinically examined at their school by a professional calibrated dentistry team. Their demographic and socioeconomic status, mouth health behaviors and teeth carries status and consumed nutritional materials were gathered by a questioner and a dental chart. The data were analyzed using inferential statistical methods. The SPSS software version 22 was used to extract the outputs and &alpha=0.05 was considered as the significant level. Results: The dental caries prevalence of deciduous, permanent and total of  two type of dents were  75.2, 41.1 and  89.8 percent, respectively and the dmft, DMFT and dmft+DMFT indexes were 3.57, 0.87, and 4.44, respectively.. The caries prevalence of permanent teeth and DMFT in girls were significantly higher than boys (p=0.046, but the caries prevalence in total of dents in boys was significantly higher than girls ( p=0.32. Furthermore, the dental caries prevalence in permanent teeth and DMFT in children resident in rural areas were significantly higher than those in urban areas (p0.1.  Conclusions: Prevalence and severity score of dental caries among 7 - 12 year-old Yasuj students were higher than the WHO standards. The tooth caries experiences were more prevalent in boys and in children resident in rural areas, increased with age and decreased with BMI and less prevalent in children with higher family socioeconomic status. Tooth brushing and flossing and consuming dairy foods were protective agents in occurring tooth caries in primary school children in

    The illusion of control can be defined as the erroneous belief that one's actions cause a specific outcome, whereas sense of agency refers to the subjective feeling of authorship over one's actions. In the present study we investigated the development of illusory control and sense of agency. A novel card-guessing game was developed in which 7- to-12-year old children (Study 1) and adults (Study 2) were required to select a card, and we manipulated the congruence of the outcome with their initial choice (i.e., congruent or incongruent) and the valence of the outcome that was presented (i.e., positive or negative). We found that illusory control and the self-attribution bias (i.e., the bias to attribute positive outcomes to oneself) in the card guessing game decreased, as children get older. In contrast, for both children and adults sense of agency in the task was similarly affected by outcome congruency, suggesting that the ability to relate predicted to observed action outcomes reflects a basic mechanism that helps people to sustain a sense of agency. Thus, while the illusion of control decreases as we get older, the experience of agency as a function of outcome congruency seems to be more stable across development.

    Full Text Available The study aimed to describe periodontal health status and its association with individual and contextual factors among 12-year-old schoolchildren in a midwest Brazilian capital city. This cross-sectional study included data from an oral health survey carried out in 2010 in the city of Goiania, Brazil and secondary data obtained from the local health authority. Data were collected through oral clinical examinations and interviews. For assessment of periodontal status two components of the community periodontal index (CPI were used: calculus and bleeding after probing. Dependent variable was presence of any periodontal condition. Independent individual variables were the children’s sex and color/race, and their mother’s level of schooling. Contextual variables were related to the schools (type and existence of toothbrushing program and its geographic location in the health districts. Rao-Scott test and multilevel Poisson analysis were performed. The prevalence of calculus and/or bleeding was 7%. Brown color, public schools, and those located in health district with intermediate socioeconomic indicators were associated to a higher prevalence of this condition. The prevalence of adverse periodontal condition was low and the inequalities in its distribution were determined by individual as well as contextual factors related to the schools and the geographic area.

    Leiomyosarcomas (LMSs) are rare malignant mesenchymal tumors which show smooth-muscle differentiation. Most LMSs involving the oral tissues primarily affect the maxillary sinus, the maxillary or mandibular bone. We present a case of LMS of the mandibular alveolar mucosa, arising in a 12-year-old male child from Ethiopia. A malignant spindle cell-like neoplasm was diagnosed on clinical and radiographic findings as well as on incisional biopsy. The tumor was resected with wide margins. The following histopathologic examination with additional immunohistochemical studies secured the diagnosis LMS. Microscopically, the spindle-shaped tumor cells were arranged in an interlacing fascicular pattern and contained oval to elongated, blunt-ended (cigar-shaped) nuclei. The immunohistochemical examination showed immunoreactive tumor cells for vimentin, actin, desmin, and H-caldesmon, which is pathognomonic for LMS. Immunohistochemical studies are mandatory to differentiate the LMS from other similar spindle cell neoplastic lesions. Radical resection with safety margins and a lifelong periodic follow-up has to be recommended.

    Full Text Available The nutcracker syndrome (NCS is a rare cause of haematuria. It embraces an extended nonpathognomonic spectrum of symptoms that imply a difficult diagnosis. Ultimately it may be associated with substantial morbidity and even life-threatening events. We report a rare cause if a 12-year-old boy who presented with a history of frequent intermittent episodes of painless constant haematuria. The cystoscopy showed a bloody urine ejaculate from the left ureter meatus. The Doppler ultrasonography showed turbulent pattern of venous blood flow of the posterior renal vein branch behind the aorta. The abdominopelvic computer tomography (apCT revealed left renal vein (LRV duplication with a dilated retroaortic branch, entrapped between the aorta and the vertebral column, promoting the renal nutcracker syndrome. The patient was initially hospitalized and managed with oral iron supplements and continuous saline bladder irrigation, not requiring additional treatment. The child is currently asymptomatic, with haemoglobin value returning to normal and therefore proposed to conservative management with close followup. The authors present a case report of episodic haematuria caused by a rare entity—posterior nutcracker syndrome with renal vein duplication.

    Background Evidence from animal and human studies suggests that early-life stress such as physical maltreatment has long-lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis and is associated with blunted HPA axis reactivity in adulthood. Few studies have investigated whether blunted HPA axis reactivity observed in children exposed to early-life stress signals social, emotional, and behavioral problems. Methods Participants were 190 12-year-old children (50.5% males) recruited from the Environmental Risk Longitudinal Twin Study, a nationally representative 1994 to 1995 cohort of families with twins. Cortisol responses to psychosocial stress were measured in maltreated/ bullied (n = 64) and comparison children (n = 126). We ascertained maltreatment and bullying victimization using mothers’ reports and assessed children’s social, emotional, and behavioral problems at ages 5 and 12 using mothers’ and teachers’ reports. Results Piecewise multilevel growth curve analyses indicated that maltreated/bullied and comparison children showed distinct cortisol responses to stress. Specifically, maltreated/bullied children had lower cortisol responses than comparison children who exhibited a significant increase. Lower cortisol responses were, in turn, associated with more social and behavioral problems among maltreated/bullied children. Conclusions These findings provide support for the influence of childhood harm on blunted HPAaxis reactivity and its potential impacton children’s functioning. Our findings emphasize the need to integrate stress biomarkers in guiding prevention efforts for young victims. PMID:21839988

    Full Text Available Background The growing prevalence of being overweight and obesity in children has raised significant public health concerns. Obesity is considered a risk factor for several chronic health conditions and is associated with increased mortality. In addition, recent studies have shown an association between obesity and periodontal disease. Objectives The present study sought to assess the correlation of body mass index (BMI with periodontal disease. Materials and Methods A total of 1,024 12-year-old elementary school students were selected by cluster sampling from five regions of Tehran. BMI was used as a measure of being overweight and obesity, and the oral hygiene index (OHI was used to assess periodontal disease. A linear regression model was applied to estimate the association between BMI and OHI. The parents’ level of education and family income were also evaluated. Results A significant association was found between BMI and OHI (P = 0.001. Also, a significant reverse correlation was detected between the parents’ education level with OHI (P < 0.05. Conclusions Obesity is not a potential risk factor for periodontal disease in children of low-income families. However, periodontal disease is associated with increased BMI. Promotion of healthy nutrition and adequate physical activity may prevent the progression of periodontal disease.

    Purpose Retinal vessel analysis is affected by both systemic and ocular factors. Malays are the major ethnicity in South East Asia. Data on the retinal microvasculature in Malays is limited, especially among children. We aim to evaluate the influence of ocular biometry on retinal vessel parameters in young Malay girls. Methods This was a cross-sectional, hospital-based study involving 86 Malay girls aged 6 to 12 years old in Hospital Universiti Sains Malaysia from 2015–2016. Ocular examination, refraction, biometry, retinal photography, and anthropometric measurements were performed. The central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE) and overall fractal dimension (Df) were measured using validated computer-based methods (Singapore I vessel analyzer, SIVA version 3.0, Singapore). The associations of ocular biometry and CRAE, CRVE and Df were analyzed using multivariable analysis. Results The mean CRAE, CRVE and Df in Malay girls were 171.40 (14.40) um, 248.02 (16.95) um and 1.42 (0.05) respectively. Each 1 mm increase in axial length was associated with a reduction of 4.25 um in the CRAE (p = 0.03) and a reduction of 0.02 in the Df (p = 0.02), after adjustment for age, blood pressure and body mass index. No association was observed between axial length and CRVE. Anterior chamber depth and corneal curvature had no association with CRAE, CRVE or Df. Conclusion Axial length affects retinal vessel measurements. Narrower retinal arterioles and reduced retinal fractal dimension were observed in Malay girls with longer axial lengths. PMID:28107389

    Full Text Available Background There is a high prevalence of iron deficiency anemia (IDA in Indonesia. Iron deficiency anemia impairs the growth and development process in children. The reference standard to diagnose IDA is serum ferritin level. Since this test is expensive and rare not widely available, an inexpensive, simpler test is needed. The Mentzer index (mean corpuscular volume/red blood cell or MCV/RBC has been used to identify hypochromic-microcytic anemia with good validity. Objective To assess the validity of the Mentzer index for diagnosing IDA by comparing Mentzer indexes to serum ferritin and to define an optimal Mentzer index cut off point with good sensitivity and specificity. Methods The study was a diagnostic test with cross-sectional design. Subjects were collected by multistage, random sampling, from April to May 2013 at 18 elementary schools in Palembang. The study had a survey phase and diagnostic test phase. Subjects were aged 6-12 years with hypochromic-microcytic anemia. We examined complete blood counts to diagnose hypochromic-microcytic anemia, calculated Mentzer indexes, and measured serum ferritin levels of our subjects. We analyzed the validity of index compared to serum ferritin level for diagnosing IDA. Results There were 100 children in our study, consisting of 51 boys and 49 girls with a mean age of 9.1 (SD 2.02 years. From the receiver-operator curve (ROC curve analysis, the area under the curve (AUC was 91.9% for a Mentzer index cutoff point of 13.51. Diagnostic test analysis revealed a sensitivity of 93%, specificity 84%, and accuracy 90%. Conclusion Mentzer index has good validity as an inexpensive and simple screen for IDA in 6-12-year-old children with hypochromic-microcytic anemia [Paediatr Indones. 2014;54:294-8.].

    Summary Early life stress (ELS) is expected to increase reactivity of the hypothalamic–pituitary–adrenocortical (HPA) axis; however, several recent studies have shown diminished cortisol reactivity among adults and children with ELS exposure. The goal of this study was to examine cortisol activity in 10–12-year-old internationally adopted children to determine if moderate and severe ELS have different impacts on the HPA axis. Salivary cortisol and two measures of autonomic activity were collected in response to the Trier Social Stress Test for Children (TSST-C). Three groups reflecting moderate, severe, and little ELS were studied: early adopted children who came predominantly from foster care overseas (early adopted/foster care (EA/FC), n = 44), later adopted children cared for predominantly in orphanages overseas (late adopted/post-institutionalized (LA/PI), n = 42) and non-adopted (NA) children reared continuously by their middle- to upper-income parents in the United States (n = 38). Diminished cortisol activity was noted for the EA/FC group (moderate ELS), while the LA/PI group (severe ELS) did not differ from the NA group. Overall, few children showed cortisol elevations to the TSST-C in any group. The presence/absence of severe growth delay at adoption proved to be a critical predictive factor in cortisol activity. Regardless of growth delay, however, LA/PI children exhibited higher sympathetic tone than did NA children. These results suggest that moderate ELS is associated with diminished cortisol activity; however, marked individual differences in cortisol activity among the LA/PI children suggest that child factors modify the impact of severe ELS. Lack of effects of severe ELS even for growth delayed children may reflect the restorative effects of adoption or the generally low responsiveness of this age group to the TSST-C. PMID:18835102

    Full Text Available OBJECTIVE: Childhood and adolescent overweight, defined by body mass index (BMI are associated with an increased risk of cardiovascular disease in later life. Abdominal adiposity may be more important in associations with cardiovascular diseases but waist circumference (WC has been rarely studied in children. We studied associations between BMI and WC and blood pressure (BP and cholesterol in 12-year-old children and prospectively changes in BMI or WC status between age 8 and 12 years and BP and cholesterol at age 12. STUDY DESIGN: Weight, height, WC, BP and cholesterol concentrations were measured in 1432 children at age 12 years. Linear regression was used to study the associations between high BMI and large WC (>90(th percentile and BP and cholesterol. RESULTS: Systolic BP was 4.9 mmHg higher (95% (CI 2.5, 7.2 in girls and 4.2 mmHg (95%CI 1.9, 6.5 in boys with a high BMI. Large WC was also associated with higher systolic BP in girls (3.7 mmHg (95%CI 1.3, 6.1 and boys (3.5 mmHg (95%CI 1.2, 5.8. Diastolic BP and cholesterol concentrations were significantly positively (HDL cholesterol negatively associated with high BMI and large WC, too. Normal weight children with a history of overweight did not have higher blood pressure levels or adverse cholesterol concentrations than children that were normal weight at both ages. CONCLUSION: A high BMI and large WC were associated with higher BP levels and adverse cholesterol concentrations. WC should be taken into account when examining cardiovascular risk factors in children.

    The aim of this study was to assess the associations of circulating levels of leptin with the peak O(2) consumption (VO(2)peak ) in 10- to 12-year-old boys of different BMI selected by Cole et al. (BMJ, 320,2000,1-6): total group (n = 248), normal (n = 190), overweight (n = 34) and obese (n = 24). We hypothesized that there is a close relationship in overweight and obese subgroups of boys with relative VO(2)peak kg (-1) (ml min(-1) kg(-1)) and leptin. Most of the subjects were Tanner stage 2. Peak O(2) consumption was measured directly using an increasing incremental protocol until volitional exhaustion on an electronically braked cycle ergometer. The expired gas was sampled continuously breadth-by-breadth mode for the measurement of oxygen consumption (MetaMax, Germany). Blood samples were obtained after an overnight fast from an antecubital vein for leptin measurements. Peak O(2) consumption (l min(-1)) was higher or lower (ml min(-1) kg(-1)) in overweight and obese groups, compared with normal BMI group. Leptin was higher in overweight and obese groups, compared with normal BMI group. Peak O(2) consumption (l min(-1)) correlated significantly with leptin only in total group (n = 248, r = 0·196). Contrary, relative VO(2)peak kg (-1) correlated significantly and negatively with leptin. The relationship was highest on the total group (r = -0·674). We can conclude that leptin first of all correlated negatively with relative peak O(2) consumption. Absolute VO(2)peak correlated with leptin only in total group.

Access to oral healthcare refers to patient's ability to obtain or utilize oral healthcare. Aim: To assess the dentition status and treatment needs among 6–12-year-old school children and to assess the factors affecting utilization of dental care among parents. Materials and Methods: A cross-sectional survey was conducted among 420 school children (6–12 years in Bangarpet taluk. Factors affecting utilization of dental care were assessed using a validated questionnaire and dentition status and treatment needs was recorded according to WHO 1997 proforma. Descriptive and inferential statistics were used. Results: The proportion of children with dmft was 62 (30% and 54 (26% in urban and rural children, respectively whereas the proportion of children with DMFT was 48 (23% and 79 (38% in urban and rural children, respectively. Among urban children 99 (47% did not need any treatment when compared to 87 (41% rural children. Around 32 (15.2% needed one surface filling in urban children and 20 (9.52% in rural children. About 30 (14.28% urban and 40 (19.04 in rural children needed preventive care, respectively. Most of the parents were not aware of fluoride content in the toothpaste. Parents agreed that maintenance of oral health is their duty. There was a significant difference between urban and rural parents for the barriers "no time to visit" (P = 0.0002, "affects my work" (P = 0.048 and "scared of injection" (P = 0.0033. Dental visits were found to be low in both urban 37 (18% and rural 56 (27% children. Conclusion: The caries experience was similar among urban and rural children. Most of the children required restorative and preventive care. Fear of injection and lack of time to visit dentist were the major barriers to parents for utilization of dental care. Hence, integrated approach is suggested to strengthen preventive and

    Background Traumatic dental injuries to anterior teeth are a significant public health problem, not only because their prevalence is relatively high, but also because they have considerable impact on children’s daily lives. Traumatic dental injuries (TDIs) cause physical and psychological discomfort, pain and other negative impacts, such as tendency to avoid laughing or smiling, which can affect social relationships. Objectives This study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12-year-old school children in Kashmir, India. Patients and Methods A cross-sectional study was conducted in private and government schools of India among 1600 schoolchildren aged 12 years. In addition to recording of the type of trauma (using Ellis and Davey classification of fractures, 1970), over jet, Angle’s molar relation and lip competence were also recorded. The socioeconomic status and academic performance of the study subjects were registered. The data obtained were compiled systematically and then statistically analyzed. The statistical significance for the association between the traumatic injury and the variables was analyzed using the chi-square test. Logistic regression was used to identify potential risk predictors of TDIs. Results The overall prevalence of TDI to anterior teeth was found to be 9.3%. The TDI to anterior teeth in male was more than female, but the difference was statistically nonsignificant (P sports were the most common causes of trauma in the present study. The highest potential risk factor for the occurrence of trauma was over jet. Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model. Conclusions It was concluded that the prevalence of traumatic dental injuries was 9.3%. Traumatic dental injuries among children exhibit complex interaction between the victims’ oral conditions and their behavior. Therefore, prevention should

    Full Text Available OBJECTIVE: To describe the prevalence of dental fluorosis, to investigate its association with individual and contextual variables among 12-year-old schoolchildren, and to determine whether there were changes in the prevalence of this condition from 2003 to 2010.METHODS: This cross-sectional study used data from an oral health survey carried out in Goiânia, Goiás, in 2010 (n = 2,075, and secondary data from the files of the local health authority. Clinical data were collected through oral examinations in public and private schools. The dependent variable was the presence of dental fluorosis, assessed using the Dean Index. The independent individual variables were sociodemographic characteristics (the child's gender and race, and the mother's level of schooling and those related to clinical conditions (caries experience, evaluated using Decayed, Missing, and Filled teeth index; and presence of periodontal calculus and/or bleeding, evaluated using Community Periodontal Index. The contextual variables were linked to the school (type and existence of toothbrushing program and its geographic location in the city's health districts. The Rao-Scott test was performed, and the percentage difference between the prevalences in the period from 2003 to 2010 was calculated.RESULTS: The prevalence of dental fluorosis in 2010 was 18.7%, being distributed as very mild (11.2%, mild (4.4%, moderate (2.6%, and severe (0.5%. No significant association was found between prevalence of dental fluorosis and the investigated variables. The prevalence of fluorosis increased 230% from 2003 to 2010, and such difference was significant.CONCLUSIONS: The prevalence of dental fluorosis was low, predominantly of the very mild degree, has increased over a 7-year period, and was not associated with the individual or contextual factors studied.

    Childhood is a critical period in the development of obesity. Eating patterns established early in life track into later life. Therefore, parental approaches to feeding in their general parenting style, feeding styles, and specific feeding practices will have a profound impact on how children eat and grow. A systematic research review following PRISMA guidelines was conducted to identify, discuss and integrate recent research investigating the relationship between parenting styles, feeding styles, feeding practices, and body mass index (BMI) in children. Medline (Ovid), PsycINFO, Web of Science, and Food Science and Technology Abstracts were systematically searched using sensitive search strategies. Studies were limited to papers published in English between 2010 and February 2015 with participants aged 4-12 years old with outcomes including obesity, change in weight, or BMI. The search yielded 31 relevant quantitative peer-reviewed papers meeting all inclusion criteria: seven longitudinal, 23 cross-sectional, one randomized control trial. Associations between parenting style and child BMI were strongest and most consistent within the longitudinal studies. Uninvolved, indulgent or highly protective parenting was associated with higher child BMI, whereas authoritative parenting was associated with a healthy BMI. Similarly for feeding styles, indulgent feeding was consistently associated with risk of obesity within cross-sectional studies. Specific feeding practices such as restriction and pressure to eat were linked to BMI, especially within cross-sectional studies. Where child traits were measured, the feeding practice appeared to be responsive to the child, therefore restriction was applied to children with a high BMI and pressure to eat applied to children with a lower BMI. Behaviors and styles that are specific to the feeding context are consistently associated with child BMI. However, since obesity emerges over time, it is through longitudinal, carefully

    The oral health status of 6- and 12-year-old Filipino children was assessed in a representative national sample of 2030 6-year-old and 2022 12-year-old children, using WHO Basic Methods for Oral Health Surveys (4th edition, 1997) and the PUFA (pulpal involvement [P/p], ulceration caused by dislocated tooth fragments [U/u], fistula [F/f], and abscess [A/a]) index. A subsample of 242 12-year-old children was included to assess backward comparability between the 1998 Oral Health Survey that used WHO Basic Methods (3rd edition, 1987). The results showed that 97% of 6-year-old children had caries (mean dmft 8.4), 85% showed dental infection (mean pufa 3.4), 20% reported pain when examined. In all, 82% of 12-year-old children had caries (mean DMFT 2.9), 56% prevalence of pulp involvement (mean PUFA 1.0), and 16% reported pain when examined. Differences in methodology between the 1998 and the 2006 surveys are likely to have had an effect on the observed reduction in DMFT, indicating that the real caries prevalence had not changed much and remains very high.

    Aim To assess the effect of combining 0.2% chlorhexidine (CHX) mouthwash with xylitol (XYL) chewing gum on Streptococcus mutans and biofilm levels among 8- to 12-year-old children. Materials and methods Sixty children aged 8 to 12 years were selected with moderate and high salivary S. mutans levels. They were divided into three groups of 20 children each: (1) XYL group where the subjects chewed XYL twice daily; (2) CHX where rinsing was done twice daily; and (3) combination of XYL and CHX group (XYL+CHX) where both the agents were used once daily. The S. mutans colony-forming units (CFUs) were counted by using the mitis salivarius agar plate at the beginning of the study and at 15 days, 1, 2, and 6 months from the start of the study. Results The XYL+CHX group showed the maximum reduction in both the biofilm and S. mutans scores throughout the study period. Conclusion The XYL+CHX combination reduced both the biofilm and S. mutans score significantly better than either XYL chewing gums or CHX mouthwash used alone.

    Full Text Available Crouzon syndrome or craniofacial dysostosis is a rare syndrome characterized by craniosynostosis, midfacial hypoplasia and exophthalmia. The abnormalities found in this syndrome change too much from case to case depending on the suture fusion order. We report a case of a 12 year old child and a mother showing variations in the dentofacial tissues clinically and radiographically. Subsequently, the application of digital software [Dolphin Imaging 11] enabled us to solve out the case as Crouzon syndrome by analyzing the skeletal and soft tissue alterations. An update of the effects of this syndrome on various systems and dentofacial features with emphasis on tooth abnormalities is documented.

    Full Text Available Background. Children in low-income developing countries are likely to suffer from undergrowth. Dental caries is another common problem in these countries. Aim. To examine the association between untreated dental caries in primary and permanent teeth with age-adjusted height and weight among 6–12-year-old children in Bangladesh. Design. Social, behavioural, and clinical data were collected from 1699 children in nine different randomly selected primary schools in socially deprived areas of Bangladesh. The associations of age-adjusted weight and height and being underweight with dental caries were examined adjusting for sex, area of residence, socioeconomic position, skipping meals, tooth cleaning, and doctor visits. Results. 26% of the children were underweight and 55% had untreated dental caries. Children with at least one decayed tooth were significantly underweight with odds ratios 1.6 (95% CI 1.1, 2.3 and 1.5 (95% CI 1.1, 2.0 for 6–8-years and 9–12-year-old children, respectively, in the adjusted model. The number of decayed teeth was inversely and significantly associated with the standardized age-adjusted weight. Conclusions. The findings highlight the association between untreated dental caries and being underweight in primary school children in socially deprived areas in low-income developing countries and emphasize the need to integrate oral and general health policies with social policies.

    Full Text Available Food consumption is playing an important role for nutritional status of children 2-12 years old. During growth and development phase, body needs macro and micro nutrients even more than later phase. The process can not be catched up at later stage therefore it is very important to pay attention to food consumption during this phase. This study used secondary data of South East Asian Nutrition Surveys (SEANUTS 2011-2012 which was covered recapitulation profile data of 300 children age 2-12 years old representative of 48 districts in Indonesia. The study showed that Indonesian children consuming less calcium and vitamin D-rich foods than the recommended daily allowance (RDA. It does not reflects on the result of anthropometry data, vitamin D on the blood and bone mass density since the dietary recall 24 hours shows only food consumption in that specific day while nutritional status shows a result of longer process. However, vitamin D in blood has a significant correlation with bone mass density of tibia bone (p<0.05. Deficiency of calcium and mainly vitamin D is a new finding at this time. Therefore, the study showed that fortification of calcium and vitamin min D in food become important to improve nutritional status of Indonesian children. 20% of RDA per serving size twice a day is recommended as well for fortification level of Calcium and Vitamin D.

    Objective The aim of the study was to investigate oral health-related knowledge, attitudes and habits and their relationship to perceived oral symptoms among 12-year-olds and differences between boys and girls. Material and methods The study population consisted of children (n = 588) in 15 randomly selected elementary schools in Turku, Finland. Associations between oral health-related habits, knowledge and attitudes with perceived oral symptoms and gender differences were evaluated with χ(2)-test, Mann-Whitney U-test and logistic regression analysis. Results Oral health promoting habits but not knowledge or attitudes associated significantly with absence of oral symptoms. Girls reported a higher percentage of several health promotional habits than boys. Girls reported more frequently gingival bleeding and less frequently dental calculus than boys did. The most common oral symptom was gingival bleeding. Conclusions The present findings suggest some gender-related differences in oral health habits, attitudes, as well as perceived oral symptoms in 12-year-olds. There seems, however, not to be gender differences in relation to knowledge or the association of health habits with perceived oral symptoms. It is important to maintain health promotion at schools and additional efforts should be aimed at translating knowledge into action.

    Full Text Available Abstract Background In recent decades low-income countries experienced an increasing trend in dental caries among children, particularly recorded in 12-year olds, which is the principal WHO indicator age group for children. This increases the risks of negative affects on children's life. Some data exist on the oral health status of children in low-income countries of Southeast Asia. However, information on how oral health is associated with socio-behavioural factors is almost not available. The aims of this study were to: assess the level of oral health of Lao 12-year-olds in urban and semi-urban settings; study the impact of poor oral health on quality of life; analyse the association between oral health and socio-behavioural factors; investigate the relation between obesity and oral health. Methods A cross sectional study of 12-year old schoolchildren chosen by multistage random sampling in Vientiane, Lao P.D.R (hereafter Laos. The final study population comprised 621 children. The study consisted of: clinical registration of caries and periodontal status, and scores for dental trauma according to WHO; structured questionnaire; measurement of anthropometric data. Frequency distributions for bi-variate analysis and logistic regression for multivariate analysis were used for assessment of statistical association between variables. Results Mean DMFT was 1.8 (SEM = 0.09 while caries prevalence was 56% (CI95 = 52-60. Prevalence of gingival bleeding was 99% (CI95 = 98-100 with 47% (CI95 = 45-49 of present teeth affected.

    Based on data from 156 typically developing 10-12-year-olds from Sweden, reading comprehension skills were studied in three subgroups: those classified with specific poor word decoding skills (n = 10), those with specific poor language comprehension (n = 12), and those with mixed difficulties in word decoding and language comprehension (n = 11). The mixed poor group achieved significantly lower scores than both specific groups in reading comprehension, and was the only group displaying poor reading comprehension test results relative to the performance of the full sample. Results are indicative of the necessity of a combined effect of poor word decoding and language in reading comprehension difficulties for this group. Implications and limitations are discussed.

    Full Text Available Objective: To report a case of a 12-year-old boy with intellectual disability and attention deficit hyperactivity disorder, who came to surgery for an examination due to a minor bulge on the left thumb, which had been growing for the previous month. His mother denied any trauma. Methods: After the removal of the clinically ambiguous bulge and a pathohistological confirmation that it was a periungual fibroma, complete patient analysis was performed due to the presence of hypomelanotic macules and a suspected tuberous sclerosis. Results: Considering the presence of hypomelanotic macules, as one of the main criteria, possible TS diagnosis was set. Conclusion: Early detection of the symptoms of TS enables a timely provision of protocols for further patient monitoring, which affects the patient’s morbidity and mortality.

    We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

    Background: radiogenic malignancies require cure of the primary disease and a prolonged survival. The introduction of high-volt technology in the 1950s and 1960s made radical radiotherapy feasible and successful in terms of higher cure rates and longer survival. We are already in a time when a higher number of patients with radiogenic secondary malignancies must be expected. Case report: a 12-year-old boy is reported who suffered from an advanced nasopharynx carcinoma and was treated with radical irradiation in 1983. 15 years later he developed a rare microcystic adnexal carcinoma of the auditory canal inside the volume of the target dose. The secondary malignant neoplasm was resected and required another radiation treatment (1 Gy b.i.d.) due to involved margins. Discussion and literature review: the entity of microcystic carcinoma is discussed with a review of the literature on biology, diagnosis, and treatment. (orig.)

    Erythromelalgia is a rare disorder characterized by recurrent pain attacks, swelling and redness in the distal extremities. The primary forms of the disorder are caused by mutations in voltage-gated sodium channels. Treatment is difficult and controlled therapeutic studies offer little to no guidance. We report on a 12-year-old boy and his first occurrence of primary erythromelalgia. Genetic findings for mutations in the SCN9A gene, which encodes for the α-subunit of sodium channel NaV1.7, were negative. Although initial treatment with sodium nitroprusside was ineffective, subsequent medication with lidocaine and mexiletine, in combination with gabapentin, was successful. Despite negative findings for mutations in the sodium channels, the use of sodium channel blockers should be considered in these patients.

    Twenty-seven children, with typical language development (TLD), 8-10 years old and 10-12 years old, were assessed with keystroke-logging in order to investigate their narrative writing. Measures of the writing process and the written product were used. One purpose was to explore how children produce written narratives in on-line production, and to relate the writing process to the written product. The results showed that those children who produced the final text faster, also wrote stories that comprised of more words. In the group of older children, children with better narrative ability used less pause time than those with worse ability, and the girls were faster writers than the boys. We believe that keystroke-logging gives valuable information for the assessment of young children's writing and that it is a potentially valid assessment tool for children from about 10 years of age.

  9. Linking adverbials in research articles across eight disciplines

    Full Text Available Biber et al. (1999 contend linking adverbials perform important cohesive and connective functions by signalling connections between units of discourse; however, there has been little previous corpus-based research in this important area of ESP. This paper describes an analysis of linking adverbials, such as “however” and “therefore”, in a corpus of 320 published research articles (RAs across eight disciplines, four science and four non-science. New lists of linking adverbials were developed and the parameters of frequency, function and disciplinary variation were examined using WordSmith Tools. They were found to be more frequent than previously thought, with numerous statistically significant disciplinary differences, for example between the sciences and non-sciences. Also, they often clustered together in complex sequences. A close examination of RAs in two of the sciences revealed some reasons for the much lower rate of occurrence there. Authors developed claims in a different way, describing methods and results in a more narrative or descriptive style rather than explicitly telling readers the connections between ideas, claims and facts. Conclusions are that linking adverbials are more important in RAs as signalling and cohesive devices, and for helping RA authors construct and strengthen claims, than previously thought by experts in this field. Also, different disciplines achieve this in significantly different ways, confirming the importance of discipline variation when researching their use.

    This study evaluated the effects of two different types of tennis lessons-those involving a technique-based approach (TBA) and those involving a game-based approach (PLAY+STAY [P+S])-on the executive functions (EFs) of junior tennis players. Eighty-one tennis players (6-12 years old) were recruited and assigned to one of three groups: TBA, P+S, or watching TV (CONT). Subjects completed evaluations of EFs (inhibitory control, working memory, and cognitive flexibility) before and after 50min programs. The overall score for EFs improved significantly for both the P+S and TBA groups but not for the CONT group; indeed the CONT group showed no improvement in overall EFs. Furthermore, the overall EF score improved more for P+S participants than for those in TBA. Looking at components of EFs, the pattern for inhibitory control reflected the pattern for the overall EF index: Improvement in the P+S and TBA groups but not in the CONT group. Only the P+S group improved in working memory. Thus, playing tennis and practicing isolated tennis skills both improved EFs of junior players more than did watching TV, and game-based tennis lessons seem to hold more promise for improving EFs than drills of tennis skills.

    This study aimed to determine the prevalence of dental fluorosis and its relationship to socioeconomic status, knowledge, and awareness among 12-year-old school children in Quetta, Pakistan. A cross sectional study was conducted among 349 school children aged 12 years in Quetta, Pakistan. By interviewing children and questionnaire for parents, socioeconomic status, knowledge, and awareness of fluorosis were collected. Dental fluorosis was examined using Dean's Index and Community Fluorosis Index. Prevalence of dental fluorosis was high (63.6%) among children with a majority of moderate and mild degree at 32.1% and 27.5%, respectively. The community fluorosis index was 1.6. While most children and parents had low-to-moderate levels of fluorosis knowledge, the majority of them worried about dental fluorosis. Most parents (84.8%) were uncertain about the condition of fluorosis in their children, and 87.4% did not know about fluorosis before. Dental fluorosis was found significantly associated with gender, family income, and parents' awareness (p ≤ 0.05). Multivariate analysis indicated that gender, and parent's awareness significantly predicted children's dental fluorosis. Knowledge and basic information regarding dental fluorosis is lacking in the community. Efforts in dissemination and communication about dental fluorosis should be increased in order to raise awareness and prevent the dental fluorosis in Pakistan.

    Previous studies have reported sex differences in wayfinding performance among adults. Men are typically better at using Euclidean information and survey strategies while women are better at using landmark information and route strategies. However, relatively few studies have examined sex differences in wayfinding in children. This research investigated relationships between route learning performance and two general abilities: spatial ability and verbal memory in 153 boys and girls between 6- to 12-years-old. Children completed a battery of spatial ability tasks (a two-dimension mental rotation task, a paper folding task, a visuo-spatial working memory task, and a Piagetian water level task) and a verbal memory task. In the route learning task, they had to learn a route through a series of hallways presented via computer. Boys had better overall route learning performance than did girls. In fact, the difference between boys and girls was constant across the age range tested. Structural equation modeling of the children’s performance revealed that spatial abilities and verbal memory were significant contributors to route learning performance. However, there were different patterns of correlates for boys and girls. For boys, spatial abilities contributed to route learning while verbal memory did not. In contrast, for girls both spatial abilities and verbal memory contributed to their route learning performance. This difference may reflect the precursor of a strategic difference between boys and girls in wayfinding that is commonly observed in adults. PMID:26941701

    We report a 12-year-old boy referred to the Clinical Genetics service in view of facial dysmorphism, learning difficulties and autistic spectrum disorder. 60K arrayCGH revealed an 8.2-Mb duplication on chromosome 13q31.3q32.3, which was paternally inherited. This specific duplication on chromosome 13 has not been previously reported in the medical literature, and there are no familial or de novo patients with the same duplication breakpoints. This region contains 24 OMIM genes, including the glypicans GPC5 and GPC6, and the ZIC2 gene. We discuss the relevance of this chromosome imbalance and discuss the impact of this duplication on our patient's phenotype. Given that the duplication on 13q was paternally inherited, and although initially thought to be of uncertain significance, on exploring the family history further, it became apparent that the father had learning difficulties as a child and previous surgery for congenital diaphragmatic hernia. Here we explore the phenotype in association with this novel duplication on chromosome 13q and add to the existing literature on array findings within this region.

    The aim of this study is to investigate associations of family-related factors with children's fruit drink/juice and soft drink consumption. A cross-sectional survey among 10- to 12-year-old children and their parents in eight European countries was conducted to gather this data. Key variables of interest were children's self-reported fruit drink/juice and soft drink intake per day (outcome) and family-related factors (based on parents' report) related to these two behaviors (modeling, automaticity, availability, monitoring, permissiveness, negotiating, communicating health beliefs, avoid negative modeling, self-efficacy, rewarding, and family consumption). 7915 Children (52% girls; mean age=11.7 ± 0.8 years) and 6512 parents (83% women; mean age=41.4 ± 5.3 years) completed the questionnaire. Multilevel regression analyses were used to examine the aforementioned associations. Three of the 11 family-related factors (modeling, availability, and family consumption) were positively associated with children's fruit drink/juice and soft drink intake. Additionally, three family-related factors (permissiveness, monitoring, and self-efficacy) were solely associated with soft drink intake and one family-related factor (communicating health beliefs) was related to fruit drink/juice intake. Future interventions targeting children's fruit drink/juice and soft drink intake should focus on the home environment, parents and their practices, especially on parents' fruit drink/juice and soft drink intake and availability of these beverages at home.

To establish the prevalence of restrictive eating problems, the overlap and association with attention-deficit/hyperactivity disorder (ADHD, and autism spectrum disorders (ASD and to estimate the heritability of eating problems in a general population sample of twins aged 9 and 12. Methods. Parents of all Swedish 9- and 12-year-old twin pairs born between 1993 and 1998 (n=12,366 were interviewed regarding symptoms of ADHD, ASD, and eating problems (EAT-P. Intraclass correlations and structural equation modelling were used for evaluating the influence of genetic and environmental factors. Cross-twin, cross-trait correlations were used to indicate a possible overlap between conditions. Results. The prevalence of eating problems was 0.6% in the study population and was significantly higher in children with ADHD and/or ASD. Among children with eating problems, 40% were screened positive for ADHD and/or ASD. Social interaction problems were strongly associated with EAT-P in girls, and impulsivity and activity problems with EAT-P in boys. The cross-twin, cross-trait correlations suggested low correlations between EAT-P and ADHD or EAT-P and ASD. Genetic effects accounted for 44% of the variation in liability for eating problems. Conclusions. In the group with eating problems, there was a clear overrepresentation of individuals with ADHD and/or ASD symptoms.

    Full Text Available Abstract Background The relative number of children meeting the minimal required dose of daily physical activity remains execrably low. It has been estimated that in 2015 one out of five children will be overweight. Therefore, low levels of physical activity during early childhood may compromise the current and future health and well-being of the population, and promoting physical activity in younger children is a major public health priority. This study is to gain insight into effects of a Physical Education based playground program on the PA levels during recess in primary school children aged 6-12. Methods/design The effectiveness of the intervention program will be evaluated using a prospective controlled trial design in which schools will be matched, with a follow-up of one school year. The research population will consist of 6-12 year old primary school children. The intervention program will be aimed at improving physical activity levels and will consist of a multi-component alteration of the schools' playground. In addition, playground usage will be increased through altered time management of recess times, as well as a modification of the Physical Education content. Discussion The effects of the intervention on physical activity levels during recess (primary outcome measure, overall daily physical activity and changes in physical fitness (secondary outcome measures will be assessed. Results of this study could possibly lead to changes in the current playground system of primary schools and provide structured health promotion for future public health.

    Full Text Available The UP4FUN intervention is a family-involved school-based intervention aiming at reducing and breaking up sitting time at home (with special emphasis on screen time, and breaking up sitting time in school among 10-12 year olds in Europe. The purpose of the present paper was to evaluate its short term effects.A total of 3147 pupils from Belgium, Germany, Greece, Hungary and Norway participated in a school-randomized controlled trial. The intervention included 1-2 school lessons per week for a period of six weeks, along with assignments for the children and their parents. Screen time and breaking up sitting time were registered by self-report and total sedentary time and breaking up sitting time by accelerometry. The effect of the intervention on these behaviors was evaluated by multilevel regression analyses. All analyses were adjusted for baseline values and gender. Significance level was p≤0.01. No significant intervention effects were observed, neither for self-reported TV/DVD or computer/game console time, nor for accelerometer-assessed total sedentary time and number of breaks in sitting time. The intervention group, however, reported more positive attitudes towards (β = 0.25 (95% CI 0.11, 0.38 and preferences/liking for (β = 0.20 (95% CI 0.08, 0.32 breaking up sitting time than the control group.No significant intervention effect on self-reported screen time or accelerometer-assessed sedentary time or breaks in sitting time was observed, but positive effects on beliefs regarding breaking up sitting time were found in favor of the intervention group. Overall, these results do not warrant wider dissemination of the present UP4FUN intervention.International Standard Randomized Controlled Trial Number Registry ISRCTN34562078.

    In India, endemic goitre is present in sub-Himalayan region and in pockets in states of Andhra Pradesh, Karnataka and Gujarat. Being a public health problem amenable for prevention, the assessment of prevalence of endemic goitre in an area helps in understanding whether the preventive strategies under National Iodine Deficiency Disorder Control Program (NIDDCP) have any impact on the control of endemic goitre. Hence, the current study was carried out to determine the prevalence, distribution and factors associated with iodine deficiency goitre among 6-12-year-old children in a rural area in south Karnataka. A cross-sectional study was conducted among 838 children, using a questionnaire adopted from Iodized Salt Program Assessment Tool and the tools prescribed by WHO for goitre survey. The prevalence of goitre in the study area was 21.9% (95% CI 19.2-24.8). There was higher prevalence of goitre among those having salt iodine 15 ppm (P = 0.01; OR 1.59; 95% CI 1.10-2.29). In 10% of the children, urinary iodine excretion (UIE) was assessed and prevalence was higher among those with goitre. The study area was found to be moderately endemic for goitre based on the WHO criteria. Higher prevalence of goitre was found to be still associated with consumption of low iodized salt (<15 ppm) necessitating emphasis on monitoring of salt iodine levels in the study area. Though NIDDCP is being implemented since five decades in India, the burden of iodine deficiency disorders (IDDs) is still high demanding further impetus to the monitoring systems of the programme.

    Full Text Available Growing evidence shows that metabolic syndrome (MetS is already starting in childhood however there is no consensus regarding how to diagnose this condition in pediatric population. Studies in adults show that altered levels of specific micro-RNAs are related with components of the MetS.We determined the plasma levels of four MetS-associated micro-RNAs (miR-126, miR-132, mir-145 and Let-7e in 10 to 12 years old children with or without MetS traits.Pediatric subjects were selected from a cohort of 3325 school-age children, and clustered by the absence (control, n = 30, or the presence of 1 (n = 50, 2 (n = 41 or 3 (n = 35 MetS traits according to Cook´s criteria. Micro-RNAs were isolated from plasma, and levels of miR-126, miR-132, miR-145 and Let-7e were determined by Taqman qPCR.Regression analysis of the different MetS traits regarding the different miRNAs analyzed showed that Let-7e presented a negative association with HDL-C levels, but a positive correlation with the number of MetS traits. Levels of miR-126 presented a positive correlation with waist circumference, waist to hip ratio, BMI, and plasma triglycerides and VLDL-C. Levels of miR-132 showed a positive correlation with waist to hip ratio. Plasma levels of Let-7e were increased (~3.4 fold in subjects with 3 MetS traits, and showed significant AUC (0.681; 95%CI = [0.58, 0.78]; p < 0.001 in the ROC analysis which were improved when miR-126 was included in the analysis (AUC 0.729; p < 0.001. In silico analysis of the interaction of proteins derived from mRNAs targeted by Let7 and miR-126 showed an important effect of both Let-7e and miR-126 regulating the insulin signaling pathway.These results suggest that changes in the plasma levels of Let-7e and miR-126 could represent early markers of metabolic dysfunction in children with MetS traits.

    Full Text Available Abstract Background Over the last decade notable progress has been made in developed countries on monitoring smoking although experimenting with cigarettes and smoking in young people remains a serious public health problem. This paper reports a cross-sectional study at the beginning of the 3-year follow-up community study TA_BES. The aim was to study the prevalence of smoking in addition to determining predictive factors for when smoking commences in a representative population of 12-year-old first year compulsory secondary education students. Methods Twenty-nine secondary schools (N = 29 from an area of Catalonia participated in the study. In these schools 2245 students answered a questionnaire to study the attitudes, behaviors, and tobacco consumption in the subject's surrounding circle and family in relation to smoking; carbon monoxide measurements were taken by means of co-oximetry on 2 different occasions. A smoker was defined as a student who had smoked daily or occasionally in the last 30 days. For non-smokers the criteria of not considering was set up for those who answered that in the future they would not be smokers and considering those who answered that they did not rule out becoming a smoker in the future. Results Among the total 2245 students included in the analysis 157(7% were classified as smokers. Among non-smokers we differentiated between those not considering smoking 1757 (78.3% and those considering smoking 288 (12.8%. Age is among the factors related to commencing smoking. The risk of becoming a smoker increases 2.27 times/year. The influence of the group of friends with a very high risk for boys OR 149.5 and lower, albeit high, in girls OR 38.1. Tobacco consumption of parents produces different effects in young people. A smoking father does not produce alterations in the smoking behavior of young people. However having a smoking mother or former smoking is a risk factor for boys and a protective factor for girls. We

    Although figures in scientific articles have high information content and concisely communicate many key research findings, they are currently under utilized by literature search and retrieval systems. Many systems ignore figures, and those that do not typically only consider caption text. This study describes and evaluates a fully automated approach for associating figures in the body of a biomedical article with sentences in its abstract. We use supervised methods to learn probabilistic language models, hidden Markov models, and conditional random fields for predicting associations between abstract sentences and figures. Three kinds of evidence are used: text in abstract sentences and figures, relative positions of sentences and figures, and the patterns of sentence/figure associations across an article. Each information source is shown to have predictive value, and models that use all kinds of evidence are more accurate than models that do not. Our most accurate method has an F1-score of 69% on a cross-validation experiment, is competitive with the accuracy of human experts, has significantly better predictive accuracy than state-of-the-art methods and enables users to access figures associated with an abstract sentence with an average of 1.82 fewer mouse clicks. A user evaluation shows that human users find our system beneficial. The system is available at http://FigureItOut.askHERMES.org.

    Full Text Available Abstract Background To determine the prevalence, intensity and extent of the Oral Impacts on Daily Performances associated with self-perceived malocclusion among Peruvian schoolchildren. Methods Eight hundred and five children aged 11 to 12 years attending 4 of 7 randomly selected schools linked to a Health Centre in Lima, Peru, participated in the study. The Spanish (PeruChild-OIDP was used to assess the prevalence, intensity and extent of oral impacts on 8 daily performances (eating, speaking, teeth cleaning, sleeping, smiling, studying, emotion and social contact. Self-perceived malocclusion included complaints about position of teeth, spacing of teeth and deformity of mouth or face. The prevalence of oral impacts was compared by covariables using the Chi-square test, whereas the intensity and extent of oral impacts were compared by covariables through the Mann-Whitney test. Results Only 15.5% of children reported impacts associated with self-perceived malocclusion during the last 3 months. Of them, 18.4% reported impacts of severe or very severe intensity and 76.0% reported impacts on only one daily performance. Psychosocial activities such as smiling, emotion and social contact were the most frequently and severely impacted everyday activities. Conclusion Impacts of self-perceived malocclusion primarily affected psychological and social everyday activities. These findings provide further evidence to support the importance of psychological and social components of oral health on children's lives.

    Background: Appetite lowering characteristics of dairy have attracted scientists to look for its effect on energy intake particularly among children. In the present study, we tried to assess the effect of low-fat milk on total and short-term energy intake among obese boys in a randomized three-way cross-over clinical trial. Methods: A total of 34 obese 10-12-year-old boys were randomized to consume three beverages (low-fat milk, apple juice, or water) with a fixed energy breakfast for two consecutive days, 1 week apart. Ad libitum lunch was provided for subjects 5 h later. The energy intake from breakfast till lunch and total energy intake on intervention days, and 2 days after intervention were compared. Generalized linear model repeated measures procedure in which test beverages were considered as repeated factors. Results: Energy intake from breakfast till lunch was lower when low-fat milk consumption was included in the breakfast compared with water and apple juice (adjusted mean ± standard error: Low-fat milk = 1484.33 ± 15.30 Kcal, apple juice = 1543.39 ± 20.70 Kcal, water = 1606.6 ± 19.94 Kcal; P 0.05). Conclusions: One serving of low-fat milk might affect the energy intake in a short-term period. The possible effect of frequent consumption of dairy products on long-term energy intake among children is needed to be examined. PMID:25538836

    Full Text Available Abstract Introduction McCune-Albright syndrome is a complex inborn disorder due to early embryonal postzygotic somatic activating mutations in the GNAS1 gene. The phenotype is very heterogeneous and includes polyostotic fibrous dysplasia, typically involving the facial skull, numerous café-au-lait spots and autonomous hyperfunctions of several endocrine systems, leading to hyperthyroidism, hypercortisolism, precocious puberty and acromegaly. Case presentation Here, we describe a 12-year-old Caucasian girl with severe facial involvement of fibrous dysplasia, along with massive acromegaly due to growth hormone excess and precocious puberty, with a prolactinoma. Our patient was treated with a bisphosphonate and the prolactin antagonist, cabergoline, resulting in the inhibition of fibrous dysplasia and involution of both the prolactinoma and growth hormone excess. During a follow-up of more than two years, no severe side effects were noted. Conclusion Treatment with bisphosphonates in combination with cabergoline is a suitable option in patients with McCune-Albright syndrome, especially in order to circumvent surgical interventions in patients suffering from polyostotic fibrous dysplasia involving the skull base.

    Introduction Television (TV) viewing is popular among adults and children, and child TV-viewing time is positively associated with parent TV-viewing time. Efforts to limit the TV-viewing time of children typically target parent rule-setting. However, little is known about the association between parent TV-viewing practices and rule-setting. Methods We used baseline height and weight data and survey data collected from 2011 through 2015 on parents and their 8- to 12-year-old children (N = 212 parent/child dyads) who were participants in 2 community-based obesity prevention intervention trials conducted in metropolitan Minnesota. Multivariable binary logistic regression analysis was used to assess the association between parent TV-viewing time on weekdays or weekend days (dichotomized as ≤2 hrs/d vs ≥2.5 hrs/d) and parent rules limiting child TV-viewing time. Results Child mean age was 10 (standard deviation [SD], 1.4) years, mean body mass index (BMI) percentile was 81 (SD, 16.7), approximately half of the sample were boys, and 42% of the sample was nonwhite. Parent mean age was 41 (SD, 7.5) years, and mean BMI was 29 (SD, 7.5); most of the sample was female, and 36% of the sample was nonwhite. Parents who limited their TV-viewing time on weekend days to 2 hours or fewer per day were almost 3 times more likely to report setting rules limiting child TV-viewing time than were parents who watched 2.5 hours or more per day (P = .01). A similar association was not seen for parent weekday TV-viewing time. Conclusion For most adults and children, a meaningful decrease in sedentariness will require reductions in TV-viewing time. Family-based interventions to reduce TV-viewing time that target the TV-viewing practices of both children and parents are needed. PMID:28103183

    Epidemiological studies have revealed several associations between asthma symptoms and environmental and dietary factors, but the potential environment- diet interactions on asthma incidence have rarely been investigated. The aim of this work was to evaluate the interrelationships between urban/rural environment, adherence to a healthy dietary pattern, the Mediterranean diet, and childhood asthma. A cross-sectional survey was performed and 1125 (529 boys), 10- to 12-year-old children were selected from 18 schools located in urban Athens area (n = 700) and from 10 schools located in rural areas of Ilia and Viotia (n = 425), Greece. Children and their parents completed standardized questionnaires, which evaluated, among others, environmental factors and dietary habits. Asthma was defined according to Phase II of the International Study on Allergies and Asthma in Childhood criteria. Adherence to the Mediterranean diet was assessed using the Mediterranean and Diet Quality Index for children and adolescents (KIDMED) score. Living in urban areas was associated with higher odds of ever had asthma symptoms by 1.78 times (95% confidence interval [CI], 1.25-2.54) when compared with rural areas. In contrast, 1-unit increase in the KIDMED score was associated with 16% lower likelihood of having asthma symptoms (95% CI, 0.77-0.91), after adjusting for various confounders. When stratifying the analysis by area of living it was observed that adherence to the Mediterranean diet was associated with lower likelihood of asthma in both urban and rural areas (urban, odds ratio [OR] = 0.81, 95% CI, 0.73-0.91; rural, OR = 0.87, 95% CI, 0.75-1.00). Urban environment seems to increase the likelihood of childhood asthma, whereas adherence to the healthy Mediterranean dietary pattern could mediate the aforementioned association and confers significant protection.

Un reconocimiento oportuno puede prevenir una anemia ferropénica, etapa final y grave de dicha deficiencia, insuficientemente conocida en nuestro país. El objetivo de este estudio fue determinar los valores hematológicos en adolescentes y conocer las prevalencias de anemia y deficiencia de hierro. Definidas como a anemia: hematocrito (Hto Iron deficiency is highly frequent among adolescents. Its early detection can prevent the development of a ferropenic anemia, a serious condition. The problem has not been well studied in our country. The purpose of this work was to determine the frequency of iron deficiency and anemia in adolescents. The criteria considered were: hematocrit below 38%, b saturation transferrin below 16%, c ferritin below 15 ng/ml. The study was carried out in 2.265 schoolchildren, 12 years old, of both sexes, in urban and periurban areas in the city of San Salvador de Jujuy (1.250 a.s.l.. The following parameters were measured: hematocrit as well as serum iron and total iron binding capacity, both by colorimetric method. Ferritin was measured by ELISA. Anemia was not found. Iron deficiency as estimated by the iron functional component, was found in 25% of girls and 21% of boys and, through iron stores, in 28% of girls and 18% of boys. Iron deficiency stores in both sexes is the more relevant alteration, indicating that the population sample here studied constitutes a highly vulnerable group. The early detection of iron deficiency will help physical and intellectual development so that adequate sanitary policies are necessary for its prevention.

    Full Text Available Abstract Background Cycling to school has been identified as an important target for increasing physical activity levels in children. However, knowledge about correlates of cycling to school is scarce as many studies did not make a distinction between walking and cycling to school. Moreover, correlates of cycling to school for those who live within a distance, that in theory would allow cycling to school, stay undiscovered. Therefore, this study examined individual, social and physical environmental correlates of never and always cycling to/from school among 10 to 12 year old Belgian children living within a 3.0 km distance from school. Methods 850 parents completed a questionnaire to assess personal, family, behavioral, cognitive, social and physical environmental factors related to the cycling behavior of their children. Parents indicated on a question matrix how many days a week their child (1 walked, (2 cycled, was (3 driven by car or (4 public transport to and from school during fall, winter and spring. Multivariate logistic regression analyses were conducted to examine the correlates. Results Overall, 39.3% of children never cycled to school and 16.5% of children always cycled to school.

    from a representative sample of 1,400 children were collected and analyzed in a cross-sectional study (year 2002. All subjects were clinically evaluated by one of two calibrated and standardized examiners. Results: 28.6% children were caries free in both dentitions. Caries prevalence in primary teeth in 6-years-old children was 72.6% and 45.0% in permanent teeth in 12-years-old children. Mean deft and DMFT were 2.98 ± 2.93 (n = 1,125 and 0.65 ± 1.43 (n = 1,379, respectively. The SiC at 12 years of age was 4.12. Children with caries experience in primary teeth were more likely to have caries in permanent teeth (odds ratio = 2.48; 95% confidence interval, 1.66-3.79 than children without caries in primary teeth. Conclusion: Low caries prevalence and experience were observed in the permanent dentition, with a substantial proportion of filled teeth. Such favorable finding was not observed in the primary dentition. Levels of caries failed to meet the oral health goal of FDI/WHO for the year 2000 in 6-years-old. However, the levels found in 12-year-olds had already met the goal for 2000. The present findings confirmed prior reports that the caries experience in primary teeth is associated with the experience of caries in permanent teeth.

    We describe the implementation of a specially designed teaching innovation, embedded in the context of energy, for the promotion of specific aspects of the nature of science (NOS). We present empirical results from the implementation of the teaching and learning materials in three intact sixth-grade classes that involved a total of 64 students. We report on students' learning gains and we discuss the ensuing implications for teaching and learning with an emphasis on epistemic ideas. The integration of activities promoting understandings of energy and specific aspects of the NOS seems to work well in impacting on students' epistemic awareness. The findings reveal interesting aspects about the interplay between understandings of energy and the NOS. The article also illustrates that it is possible to teach productively specific aspects of a consensus view of the NOS from a fairly young age without having to rely on advanced science knowledge or explore the intricacies and differentiations across science disciplines.

    Background: The 12 years-old children population is worldwide taken as a reference age to compare the buccal health condition of different countries, by means of various indicators that measure the presence of the main buccal diseases. The knowledge of these epidemiological profiles generates information to guide the services planning policies of the Primary Health Care. Objective: To characterize 12 years-old population's buccal health condition. Methods: Cross- sectional descriptive correlative study with a stratified probabilistic sample of 90 children starting from a universe conformed by the 269 adolescents that constitute the total of the 12 years old population of the Health Care Area VIII in Cienfuegos municipality. Pearson’s chi-square and Mantel-Haenszel lineal tendency tests were used with the determination of the relative risk and reliance intervals of 95%. Results: The decay prevalence reached 54, 4%. The COP-D index was 2, 45 being the decayed component the major percentage with 4.6%. The periodontal disease was more frequent in boys than in girls, with 54, 9% and 30, 8% respectively. 80,9% of the segments is healthy. In those affected, the calculation prevailed in 11,7%. It was determined that faulty obturations, inheritance and faulty buccal hygiene were the most affecting risk factors for children with decays, while in the periodontal disease it was faulty buccal hygiene. Malocclusions presented a prevalence rate of 40%. Out of which, 55,6% required secondary level attention. Those with habits present a risk 2 times superior of making sick. The sick epidemiological category was present in 77,8% of the total. Conclusions: We emphasize the prevention need as core issue of the primary medical care in the world today; being the General-Integral Dentist a transforming agent that according to his/her formation is capable to assume the existent

    Full Text Available A prevalência dos anticorpos neutralizantes contra os três tipos de poliovírus e os níveis de imunidade para diferentes grupos etários foram determinados, através de um inquérito soro-epidemiológico, numa população de crianças de 0-12 anos de idade, residentes no município de São Paulo, Brasil e assistidas pelo Hospital Menino Jesus. Os resultados mostraram um número elevado de crianças suscetíveis à infecção por poliovírus no primeiro ano de vida, particularmente no grupo etário de 9-12 meses, em que a proporção de crianças completamente desprotegidas (triplo-suscetíveis alcançou 42,5%. Neste grupo, a prevalência de anticorpos dos tipos 1, 2 e 3 foi apenas em torno de 40%. Dentre as crianças do grupo etário de 0-5 anos, que receberam três ou mais doses de vacina oral trivalente, verificou-se a baixa proporção de 60% de duplo mais triplo-imunes. Os resultados mostraram que o estado imunitário das crianças deste grupo foi o mesmo nas três zonas geográficas da Capital, sendo em torno de apenas 50% a proporção de crianças duplo mais triplo-imunes. Estes resultados indicam níveis precários de imunidade, particularmente nas crianças do primeiro ano de vida. Existe, pois, uma necessidade evidente de realizar novos inquéritos sorológicos, além de intensificar e melhorar a vacinação de manutenção contra a poliomielite em nosso meio.The prevalence of neutralizing antibodies for the three types of polioviruses and the immunity levels of different age groups were determined through a seroepidemiological survey, in a population of 0 to 12 year old children, living in the city of S.

    fluorosis, 45.9% of the children had TFI 1, 6.1% TFI 2 and 0.9% TFI 3. A polarization of the experience of caries and gingivitis was observed in the studied population. Only 14.4% of the students had DMFS higher than 7. A small percentage of children (12% presented with BI ³ 40%. The experience of caries and gingivitis of 12-year-old schoolchildren in Porto Alegre is comparable to that of children from developed countries. That probably results from the intense utilization of fluoride, which is also causing an increased prevalence of fluorosis. The severity of fluorosis does not justify any public health measure. The results show that the employed public health measures are effective, although part of the population still needs additional care.

    Objective Cerebral palsy (CP) is a non-progressive CNS disorder due to an insult to the growing brain, usually occurring in the first two years of life. During the recent years, its etiology has been changed; perinatal and postnatal insults are not considered as its main causes in developed countries any more. The aim of this study was to evaluate the causes of CP in children in southern Iran. Materials & Methods Overall, 200 children with CP aged 1-12 yr old referring to Pediatric Neurology Clinic affiliated to Shiraz University of Medical Sciences, Shiraz, Iran between 2012 and 2013 were enrolled. In addition, 200 healthy age and sex-matched children were considered as the control group. Exclusion criteria were isolated movement disorders with no other evidence of CP, progressive neurologic disorders, metabolic disorders, and incomplete or uncertain past history. After collecting the data on pregnancy period, prenatal history and past medical problems, they were analyzed with appropriate statistical methods. Results Maternal age, medical problems during pregnancy period, route of delivery, head circumference at birth, neonatal admission, neonatal jaundice, and prematurity were the main risk factors for CP. Discussion The distribution of risk factors of CP is different from that of developed countries in our region. Pre- and peri-natal etiologies are still among the common causes of CP in Iran.

    Full Text Available Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the microorganisms responsible for the post-dysenteric form. The human leukocyte antigen (HLA-B27 antigen is the best-known predisposing factor. We report a case of HLA-B27-associated reactive arthritis after Salmonella enteritis at Pusan National University hospital.

    The aim of this cross-sectional study was to evaluate the relationships between cognitively engaging exercise (i.e., game-based and coordination exercises), executive functions (i.e., inhibitory control and working memory), and physical fitness. Forty junior tennis players (6-12 years old), who regularly participated in tennis lessons (2.55 years, SD = 1.61) prior to the study, were investigated. All participants completed evaluations of executive functions (inhibitory control and working memory) at rest. The duration of each lessons' instructional activities, including coordination training, game-based exercise, rallying, and non-physical activity (explanations and breaks), was recorded. Physical fitness was evaluated using the Tennis Field Test. A longer duration of game-based exercise was positively correlated with inhibitory control and physical fitness. Coordination training was associated with improved working memory. Non-physical activity was inversely correlated with inhibitory control, working memory, and physical fitness. The results suggest that game-based tennis lessons have beneficial effects on inhibitory control and physical fitness levels, and a longer duration of coordination training is associated with better working memory. The present study indicates that shortened non-physical activity time within a sports setting is associated with the development of executive functions and physical fitness.

    Aim: The aim of the present study was to evaluate the relationship of drinking water fluoride levels with children's intelligence quotient (IQ). Materials and Methods: Water was collected from initially identified endemic fluoride regions according to the geological research of Government of India. Fluoride concentration of the water was assessed by utilizing fluoride ion selective electrode, Orion 9609BN, and categorized on the basis of fluoride concentration into low, medium, and high-fluoride regions, i.e., Virajpet (low fluoride level 3 ppm). Government school from all three villages were selected randomly and IQ levels were assessed by using Raven's Standard Progressive Matrices. This test was conducted on each child in the study sample. Results: A significant inverse relationship was found between the fluoride concentration in drinking water and IQ (r value = −0.204; P < 0.000). It was observed that IQ level was negatively correlated with fluoride concentration in drinking water. Conclusion: It is concluded that IQ level was negatively correlated with fluoride level in drinking water. Factors that might affect children's IQ need to be considered, and it is necessary to devise solutions for preventing the harmful effects of excessive intake of fluoride ion to the body.

    To be successful takes creativity, flexibility, self-control, and discipline. Central to all those are executive functions, including mentally playing with ideas, giving a considered rather than an impulsive response, and staying focused. Diverse activities have been shown to improve children's executive functions: computerized training, noncomputerized games, aerobics, martial arts, yoga, mindfulness, and school curricula. All successful programs involve repeated practice and progressively increase the challenge to executive functions. Children with worse executive functions benefit most from these activities; thus, early executive-function training may avert widening achievement gaps later. To improve executive functions, focusing narrowly on them may not be as effective as also addressing emotional and social development (as do curricula that improve executive functions) and physical development (shown by positive effects of aerobics, martial arts, and yoga).

    Full Text Available The present study aimed to evaluate the need for orthodontic treatment in Brazilian schoolchildren presenting both late mixed dentition and early permanent dentition as well as to determine the possible factors associated with this necessity. Our randomly selected sample consisted of 407 schoolchildren aged between 9 and 12 years from Nova Friburgo (State of Rio de Janeiro, Brazil. All the children were evaluated according to the two components of the Index of Orthodontic Treatment Need (IOTN, namely, the Dental Health Component (DHC and the Aesthetic Component (AC. Data analysis involved multiple logistic regression. Definite need for orthodontic treatment was found in 34.2% and 11.3% of the children according to, respectively, DHC and AC. The most prevalent malocclusions included the following: contact point displacement (crowding, crossbite, and increased overjet. Male gender, permanent dentition and aesthetic reasons were factors associated with a great need for orthodontic treatment. It was concluded that about one-third of the children evaluated had a definite need for orthodontic treatment. This necessity was greater in the permanent dentition, thus emphasizing the importance of an early identification of malocclusions and a timely referral of patients for treatment. The correlation between AC and DHC was considered important since they involve distinctive characteristics.

    1980-11-01

    Eleven tests of specific cognitive abilities were administered to 108 pairs of young twins (average age of 7.6 years). Internal consistencies are high for all measures except Raven's Coloured Progressive Matrices and Delayed Picture Memory. Two-month, test-retest reliabilities are also reported. The twin sample is representative in terms of both means and variances when compared to normative data from standardization samples, and twin correlations for height and weight are similar to those obtained in six other twin studies. Because all measures were highly correlated with age (average correlation with age was 0.64), scores were aged adjusted. Previous twin studies of specific cognitive abilities in adolescents and adults found genetic variance for nearly all tests. In contrast, our study of young twins yielded significant genetic influence for only 1 of the 11 measures, PIAT Reading Recognition, and suggested the possibility of genetic influence on 2 others (vocabulary and WISC-R mazes). Environmental influences seem to dominate, particularly for nonverbal measures, as children begin their education. In accord with other studies, we found that between-family environmental factors have an important influence on the development of nearly all of the measures of specific cognitive abilities. However, we found that our tests of perceptual speed and memory were substantially influenced by within-family environmental factors independent of error.

The methodology proposed by the World Health Organization (1997 was used for caries diagnosis in 2,378 individuals. According to the DMFT index obtained in each evaluated city, 3 prevalence groups with representative samples were formed, being classified as low, moderate and high. SiC index was used to classify the one third of the population with the highest caries prevalence. In the low prevalence group, 32.4% of the children were caries free (DMFT=0, with mean DMFT of 2.29 and SiC index of 4.93. In the moderate prevalence group, 21.8% of the children were caries free, with mean DMFT of 3.36 and SiC of 6.74. Only 6.9% of the children in the high prevalence group were caries free and the mean DMFT was 5.54 (SiC=9.62. There was a great heterogeneity in dental caries distribution within the studied population, as well as a high caries prevalence considering the 3 classifications. Other indexes besides DMFT could be used to improve oral health assessment during establishment of the treatment plan and intervention.

    Full Text Available The cause for severe, recurrent lower gastrointestinal (LGI bleeding in children can usually be diagnosed readily by means of the commonly used investigative/diagnostic techniques such as colonoscopy, laparoscopy ± laparotomy. Occasionally less commonly used investigations may be necessary to look for more elusive causes of LGI bleeding such as capsule endoscopy, angiography, technetium-99m (99m Tc-labeled red blood cell (RBC scintigraphy, cross-sectional imaging such as CT/MRI (including angiography and laparotomy combined with on-table small bowel enteroscopy. We report a case of severe, recurrent LGI bleeding that had occurred over several years, where the cause remained elusive despite numerous investigations and interventions. The etiology of this was eventually found to be a gastric duplication cyst infiltrating into adjacent transverse colon and causing bleeding from peptic ulceration in the colon. The process by which this diagnosis was made and the lessons learned are discussed.

    BACKGROUND: Nearly 45% of all deaths are associated with chronic fibroproliferative diseases, of which the primary characteristic is altered remodelling of the extracellular matrix. A major difficulty in developing anti-fibrotic therapies is the lack of accurate and established techniques...... to estimate dynamics of fibrosis, regression or progression, in response to therapy. AIM: One of the most pressing needs in modern clinical chemistry for fibroproliferative disorders is the development of biomarkers for early diagnosis, prognosis, and early efficacy for the benefit of patients...... and to facilitate improved drug development. The aim of this article was to review the serological biomarkers that may assist in early diagnosis of patients, separate fast from slow- or nonprogressors, and possibly assist in drug development for fibroproliferative diseases, exemplified by liver fibrosis.

    Full Text Available X-linked agammaglobulinemia (XLA is a primary immune deficiency characterized by recurrent bacterial infections and profoundly depressed serum immunoglobulin levels and circulating mature B cells. We describe a 12-year-old boy with XLA and enthesitis-related arthritis (ERA. To date, there has been a paucity of reports of noninfectious inflammatory arthritis in children with XLA. This case illustrates that functional B cells and/or immunoglobulin are not required for ERA pathogenesis. In addition, this case suggests a possible link between immune deficiency, immune dysregulation, and rheumatic illness.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    The purpose of this work is to analyze, in a pilot study, the effects of video modeling and imagery training over 24 weeks on tennis service performance. Three groups of 9- to 12-yr.-old tennis players participated: (a) a physical practice group, who received physical training, (b) a physical practice + video group who received physical training plus watched a video modeling mental training, and (c) a physical practice + video + imagery group who received physical training plus video modeling and imagery mental training. The results for the intragroup pre-post-test comparisons showed that tennis performance did not significantly improve for the physical training group. The groups given mental training showed improvement from pre- to postintervention. Finally, the posttest comparison between groups indicated that there were significant differences between the group given physical training only compared to the groups given mental training but that the latter two did not differ significantly from each other.

    Tics are the most frequent movement disorder in children and they are most prevalent during the school-age years. Most tics are transitory; however, certain tics can be chronic, causing negative repercussions at school, within the family, and socially. In some cases, tics are associated with obsessive compulsive disorder, attention-deficit hyperactivity disorder (ADHD) and other conditions that require diagnosis and prompt treatment. In South America, there are no indexed studies determining the prevalence of tics in school-age children. The aim of this study was to establish the prevalence of tics in schoolchildren aged 6 to 12 years. From 16 000 students aged 6 to 12 years who were enrolled in first to fifth grade, a sample of 346 school-aged children was chosen via a multistage sampling process that randomized the educational systems in terms of proportional size and the stratification between public and private schools and adjusted for the design effect. The students were screened and those who were positive for tics underwent clinical evaluations and semistructured interviews by the researchers to determine the prevalence of the disease. The parents and teachers of 323 students returned our surveys (93.3%). One hundred thirty-eight students (42.7%) were considered positive for tics based on parents' and teachers' reports. The clinical evaluation established a 17.97% prevalence of tics (58 students), and 25 students (43.2%) also met diagnostic criteria for ADHD. Of the students with tics, 27.6% presented with transitory tics, and 72.4% presented with chronic tics. Gilles de la Tourette syndrome was detected in 11 of the children (3.4%). The average age of child with tics was 9 ± 1.5 years, and the majority of the children with tics attended third grade at a basic primary school. Children from public and private schools were equally likely to present with tics. Tics are noteworthy in our field and are associated with other neurobehavioral disorders, such as ADHD. Both tic disorders and ADHD require diagnosis and prompt treatment to promote social and school performance.

  10. Perioral Dermatitis after Dental Filling in a 12-Year-Old Girl: Involvement of Cholinergic System in Skin Neuroinflammation?

    Directory of Open Access Journals (Sweden)

    Fabrizio Guarneri

    2008-01-01

    Full Text Available The etiopathogenesis of perioral dermatitis (PD is still unknown and, consequently, medical treatment is difficult, not precisely defined, and often unsatisfactory. On the basis of a peculiar case that appeared soon after multiple dental fillings with a mercury-containing amalgam, we proposed that neurogenic inflammation could play a role in the pathogenesis of PD. According to the new findings provided by clinical and basic research, neurogenic inflammation has a relevant part in the pathogenesis of many cutaneous diseases. We report a similar case of PD, taking into account, more specifically, the possible involvement of the cholinergic system. Also in this case, PD seems to be mainly related to the mercury contained in dental fillings and/or its organic compounds formed by oral/gut bacteria. We examined the possible role of these substances as causes of PD, providing new information on the possible cross-talk between neuroimmunodermatology and potential triggers of PD.

    It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis-stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

    Full Text Available Background: It has recently been revealed that H. pylori infection is one the most important causes of anemia inhibiting iron uptake. The current study was designed to evaluate the correlation between the iron deficiency anemia and IgG to H. pylori in anemic children. Methods: In this analytical study, 100 anemic children were analyzed using total Iron, Ferritin, TIBC and H. pylori IgG assay. Data were collected using a questionnaire including parameters of age, blood group, infancy nutrition, iron consumption, fatigue, weakness, height, weight, gastrointestinal infectious, parasitic and blood diseases, parent literacy, income, inhabitation, etc. Data were analyzed using Multivariate Regression Analysis Models, Pearson Correlation- test and Kolmogrov Smirnov. Results: The most prevalent blood group detected in the study sample was group O (62%; 79% were breastfed, 9% were bottle- fed, 12% were both breastfed and bottle- fed. The history of gastrointestinal disorders was mentioned amongst 91% of the patients′ family members. A significant relationship was observed between the iron level with serum, ferritin, level of TIBC and elevated level of IgG titer to H. pylori (p < 0.001. There was a significant association between the shared dishes, GI disorders, fatigue and weakness and level of TIBC, ferritin, Iron and IgG (p < 0.001. Conclusions: The significant relationship between the iron level, IgG titer and H. pylori infection rate can be referred to as important factors influencing the anemia rate. Therefore, H. pylori IgG test can be checked for anemia together with the other routine tests.

    Several studies investigating the relationship between body mass index (BMI), waist circumference (WC), and/or body fat (BF) with macronutrient composition of the diet have suggested that dietary composition may play an important role to overweight/obesity in childhood, but its relation remains inconclusive. The aim was to assess the association between energy intake (EI) and macronutrient diet composition with overweight/obesity among children.Nonrandomized cohort study including 396 Italian children and preadolescents (9-13 years old), 200 overweight/obese and 196 normal-weight. The children's weight, height, WC, and food intake were measured.Reported EI was higher in overweight/obese than in nonoverweight children; however, after body weight was considered, the overweight/obese children had less EI than their leaner counterparts. Percentages of EI from proteins, SFA, MUFA and PUFA (in males), and dietary fiber (g/1000 kcal) were higher in the overweight/obese children than in the leaner ones. EI from carbohydrates and fats was lower in overweight/obese males and females, respectively. Positive correlations between BMI and waist-to-height ratio with EI from proteins were found in males (r = 0.296, P regression, the highest EI from proteins were associated with higher odds ratio for overweight/obesity, while the lowest EI from carbohydrates was associated with higher odds ratio for overweight/obesity in males.Reported EI of overweight/obese children was higher than nonoverweight peers. Overweight/obese children had higher intakes of proteins compared with nonoverweight ones. Overweight/obese males and females showed lower EI from carbohydrates and fats, respectively, than their leaner counterparts.

    Directory of Open Access Journals (Sweden)

    Sorin Paliga

    1999-12-01

    Full Text Available I shall attempt to resume a long, almost endless discussion: the origin of the Romanian definite article. Any grammar of Romanian or any comparative grammar the Romance languages (e. g. Tagliavini 1977 always observes that Romanian, an iso­ lated case in the Romance family, has an agglutinated definite article. The typology is not indeed rare: Bulgarian, Albanian, Armenian, Basque and Swedish witness the same mechanism. We cannot approach the topic by analysing all these languages, yet a comparative analysis would be finally useful. In our case, it is obvious that Romanian cannot be isolated from Albanian and Bulgarian. A potential solution must explain the situation in ALL these three "Balkanic" languages, even if Romanian is not Balkanic stricto sensu1. The paper shall focus on the deep roots of the Romanian and Albanian definite arti­ cle, its typological relations with other linguistic areas, and shall attempt to explain this isolated situation in the field of Romance linguistics. For sure, the Romanian definite article mainly reflects the Latin heritage. Nevertheless, by saying only this, the tableau is not complete: some forms are not Latin but Pre-Latin, Thracian. This paper will try to substantiate this assertion.

  11. Preventive and interceptive orthodontics for the 5 to 12 year-old. Functional appliances: the Nite-Guide and Occlus-o-Guide techniques.

    Kleinerman, V; Bergersen, E O

    2011-04-01

    hree orthodontic procedures are described that are used to prevent, intercept, and correct malocclusions at three distinct stages of dental development. Each stage of development (5 to 7 years, 8 to 12 years, and 12 years through adulthood) uses an appliance selected from a series of several preformed sizes. All have predicted socket dimensions to receive unerupted, erupting or fully erupted teeth. These sockets are prearranged in a perfect Class I occlusion. In the first group of appliances, specifically designed for the 5 to 7 year-old (called Nite-Guide), one selects a single size that is large enough to accommodate the teeth after they become straight. This appliance is worn passively while sleeping and simply guides the incoming incisors to straighten themselves using only their own force of eruption. Once straight, the adult collagenous fibers form and thereby prevent most future relapse from occurring. At the same time, the incoming incisors are prevented from over-erupting into a deep overbite and the mandible is advanced to correct any excess overjet. Similarly-designed appliances are also used to correct malocclusions in the mixed and adult dentitions. To obtain optimum results at these ages, active wear of about two hours per day is required. The treatment time is very fast (1 to 12 months in most cases) and the same appliance is also used as the retainer of choice. Most malocclusion problems such as crowding, rotations, overbite, overjet and TMD are 80 to 95% corrected in those wearing the appliance as directed.

    Full Text Available Objectives: Treating a carious tooth in children with high caries experience by providing a restoration does not cure the disease. If the unfavorable oral environment that caused the cavity persists so will the disease and more restorations will be required in future. Treating the oral infection by reducing the number of cariogenic microorganisms and establishing a favorable oral environment to promote predominantly remineralization of tooth structure over time will stop the caries process. The present study was conducted: (1 To evaluate the efficacy of povidone-iodine and chlorhexidine mouth rinses on plaque Streptococcus mutans when used as an adjunct to restoration. (2 To compare the anti-microbial effect of 1% povidone-iodine and 0.2% chlorhexidine mouth rinses on plaque S. mutans count. Study Design: Forty-five study participants in the age group of 6-12 years with dmft (decay component of three or four were selected from one government school in Bangalore city. They were divided into three groups after the restorative treatment. Group-A, Group-B, and Group-C received 1% povidone-iodine mouth rinse, 0.2% chlorhexidine mouth rinse and placebo mouth rinse, respectively, twice daily for 14 days. The plaque sample was collected and S. mutans count was estimated at six phases: (1 Baseline, (2 3 weeks after restoration, (3 First day after mouth rinse therapy, (4 15 days after mouth rinse therapy, (5 1 month and (6 3 months after mouth rinse therapy Results: After the restoration the percentage change in S. mutans count was 28.4%. Immediately after mouth rinse therapy there was significant reduction in S. mutans count in all the three groups. After which the count started to increase gradually and after 3 months the bacterial counts in the povidone-iodine group and placebo group were almost near the postrestorative count. Conclusion: Mouth rinses can be used as adjunct to restoration for short duration as temporary measure in reduction of S. mutans count and restorations provide longer effect. In case a mouth rinse has to be used, chlorhexidine can be recommended as it has shown to have better effect than Povidone-iodine and placebo.

The aim of the present study was to examine effects of the APPsw transgene on memory of AD minipigs compared with non-transgenic controls at two ages (1–2 years) using the spontaneous object recognition test (SORT), which is based on behavioural...... discrimination of familiar and novel objects. No significant difference between AD minipigs and controls was found when comparing object recognition as a measure of memory. The minipigs did explore the novel object significantly more than the familiar, indicating the expected recognition of the familiar object....... Two different inter-phase intervals were used (IPI: 10–40 min). For both ages, object recognition was evident using 10 min IPI. When using 40 min IPI, object recognition was evident only at age 1 year. Comparing memory of a relatively small group of AD minipigs and controls at two rather young ages...

    Gender assignment of children with intersexuality and related conditions has recently become highly controversial. On the basis of extensive animal research and a few human case reports, some authors have proposed the putative masculinization of the brain by prenatal hormones-indicated by the degree of genital masculinization-as the decisive criterion of gender assignment and have derived the recommendation that 46,XX newborns with congenital adrenal hyperplasia (CAH) and full genital masculinization should be assigned to the male gender. The purpose of this study was to test in CAH girls of middle childhood the assumption that prenatal androgens determine the development of gender identity. Fifteen girls with CAH (range of genital Prader stage, 2-4/5), 30 control girls, and 16 control boys (age range, 5-12 years) underwent 2 gender-play observation sessions, and a gender identity interview yielding scales of gender confusion/dysphoria. About half a year earlier, mothers had completed 2 questionnaires concerning their children's gender-related behavior. The results showed that, as expected, CAH girls scored more masculine than control girls on all scales measuring gender-related behavior, with robust effect sizes. By contrast, neither conventionally significant differences nor trends were found on the 3 scales of the gender identity interview. We conclude that prenatal androgenization of 46,XX fetuses leads to marked masculinization of later gender-related behavior, but the absence of any increased gender-identity confusion/dysphoria does not indicate a direct determination of gender identity by prenatal androgens and does not, therefore, support a male gender assignment at birth of the most markedly masculinized girls.

    Full Text Available The purpose of the study is to monitor the effect of 8-week dynamic stretching exercises on flexibility development and swimming performance in male swimmers in 10-12 age group. The study is carried out among 30 boys between ages of 10-12 who regularly do swimming exercises in a variety of sport clubs in Konya. The children taking part in the research is divided in experiment group (EG (age=10,93±0,80 years, height=150,94±0,06 cm, weight=43,07±3,13 kg and control group (CG (age=11,00±0,85years, height=151,7±0,05 cm, weight=47,80±3,61 kg, each of 15. In the course of 8 weeks, experiment group performed dynamic stretching exercises in addition to the swimming exercises while CG only did swimming exercises. In analysing the results Paired Samples T-Test and Independent Sample T-Test has been used. At the end of the study, it was identified that EG made a significant progress in sit-and-stretch, arm flexibility, bridge pose, hip flexion and extension, knee flexion, shoulder flexion, torso flexion and 25-50-200 freestyle and technical swimming tests (p˂0,05. On the other hand, no substantial change was observed in any of CG’s flexibility parameters (p˃0,05. It was revealed that experiment group’s extension values were profoundly higher and its 25 meter swimming and turns in 50-100-150-200 meters were significantly shorter compared to the control group (p˂0,05. Consequently, it is possible to claim that dynamic stretching exercises performed before swimming exercises make substantial contribution to the flexibility and performance development of swimmers who are in the adolescence period.

    Indonesia is currently facing the double burden of malnutrition. While undernutrition is still a major public health problem, the prevalence of overnutrition is increasing. The objective of the South East Asian Nutrition Survey (SEANUTS) was to provide up-to-date data on nutritional status, food consumption and biochemical parameters related to nutrition for children aged 0·5-12 years. The SEANUTS study in Indonesia was conducted in a nationwide representative sample of 7·211 children using multistage cluster sampling based on probability proportional to size, stratified for geographical location, in forty-eight out of 440 districts/cities. The results show that the growth (weight for age, height for age, weight for height and BMI for age) of Indonesian pre-school- and school-aged children is below the WHO standards. The older the children, the more the deviation from the WHO standard curves. Underweight was more prevalent in rural areas (28·9 v. 19·2%) and overweight/obesity was observed to be more widespread in urban areas (5·6 v. 3·2%). The prevalence varied with age groups and sexes. The overall prevalence of stunting was 25·2 and 39·2% in urban and rural areas, respectively. The prevalence of anaemia was nearly 55% in children aged 0·5-1·9 years and ranged from 10·6 to 15·5% in children aged 2-12 years. Fe deficiency was observed in 4·1-8·8% of the children. The percentage of children with dietary intakes of energy, protein, and vitamins A and C below the Indonesian RDA was high and differed across urban and rural areas and age groups.

    2016-05-01

    Primary amoebic meningoencephalitis (PAM) is a rare and almost always fatal disease that is caused by Naegleria fowleri, a freshwater thermophilic amoeba. Our case involves an adolescent female who presented with fever of unknown origin. A lumbar puncture was performed, and the Wright-Giemsa and Gram stained cerebrospinal fluid (CSF) cytospin slides showed numerous organisms. Experienced medical technologists in the microbiology and hematology laboratories identified the organisms as morphologically consistent with Naegleria species. The laboratory made a rapid diagnosis and alerted emergency department care providers within 75 minutes. The patient was treated for PAM with amphotericin, rifampin, azithromycin, fluconazole and aggressive supportive therapy including dexamethasone. The Centers for Disease Control and Prevention (CDC) was contacted, and miltefosine, an investigational medication, was started. Additional treatment included an intraventricular shunt and controlled hypothermia in order to mitigate potential cerebral edema. Our patient is a rare success story, as she was diagnosed swiftly, successfully treated, and survived PAM.

    An adequate coordination level in children is important for their general development, but also for health, psychosocial, academic and well-being-related reasons. In this study, the suitability of the KörperkoordinationsTest für Kinder (KTK) as an assessment instrument for the gross motor coordination was evaluated in 2470 children from 26 elementary schools for general education spread over the Flemish and Brussels-capital region. All children performed four subtests: walking backwards (WB), moving sideways (MS), hopping for height (HH) and jumping sideways (JS). Age and gender-specific values were established for the Flemish children anno 2008. Overall, the current sample scored significantly worse than their 1974 German counterparts (P<0.001). Score distribution showed 21% of the children being placed in the problematic range of gross motor coordination level. A decline in coordination was observed especially in those tasks relying primarily on coordinative capacities (WB and MS), while improvements or status quo in those tasks relying on strength and speed (JS and HH) were explained by secular trends. We suggest that the KTK is a valuable instrument for the assessment of the gross motor coordination of Flemish children and efforts should be made in order to face the decline in coordination.

    Aim Research suggested a positive association between physical fitness and neurocognitive functioning in children. Aim of the present study is to investigate possible dose-response relationships between diverse daily physical activities and a broad range of neurocognitive functions in preadolescent children. Furthermore, the relationship between several sedentary behaviours, including TV-watching, gaming and computer time, and neurocognitive functioning will be investigated in this group of children. Methods A total of 168 preadolescent boys, aged 8 to 12 years, were recruited from various locations, including primary schools, an amateur soccer club, and a professional soccer club, to increase variability in the amount of participation in sports. All children performed neurocognitive tasks measuring inhibition, short term memory, working memory, attention and information processing speed. Regression analyses examined the predictive power of a broad range of physical activities, including sports, active transport to school, physical education (PE), outdoor play, and sedentary behaviour such as TV-watching and gaming, for neurocognitive functioning. Results Time spent in sports significantly accounted for the variance in inhibition, short term memory, working memory and lapses of attention, where more time spent in sports was associated with better performance. Outdoor play was also positively associated with working memory. In contrast, time spent on the computer was negatively associated with inhibition. Conclusions Results of the current study suggest a positive relationship between participation in sports and several important neurocognitive functions. Interventions are recommended to increase sports participation and to reduce sedentary behaviour in preadolescent children. PMID:27906965

    Reducing glycaemic index (GI) and glycaemic load (GL) inconsistently improves aspects of cognitive function and appetite in children. Whether altering the GL by lowering carbohydrate relative to protein and fat has a role in these effects is unknown. Therefore, we assessed the differential effects of beverages varying in GL and dairy composition on appetite, energy intake and cognitive function in children. A total of forty children (10–12 years) completed a double-blind, randomised, crossover trial, receiving three isoenergetic drinks (approximately 1100 kJ): a glucose beverage (GI 100, GL 65), a full milk beverage (GI 27, GL 5) and a half milk/glucose beverage (GI 84, GL 35). For 3 h post-consumption, subjective appetite and cognitive performance (speed of processing, memory, attention and perceptual speed) were measured hourly. At completion, each child was provided a buffet-style lunch and energy intake was calculated. Blood glucose was objectively measured using the Continuous Glucose Monitoring System. Blood glucose AUC values were significantly different between the drinks (P,0·001), but did not sustain above the baseline for 3 h for any drink. Mixed modelling revealed no effect of beverage on subjective appetite or energy intake. Participant sex and drink GL significantly interacted for short-term memory (P,0·001). When girls consumed either milk-containing beverage, they recalled 0·7–0·8 more words compared with 0·5 less words after the glucose drink (P#0·014). Altering GL of drinks by reducing carbohydrate and increasing protein did not affect appetite or cognition in children. Girls may demonstrate improved short-term memory after consuming beverages with higher protein and lower GL.

The study included a total of 64 children, of which 43 were boys and 21 were girls, ages 10-12. All subjects have been regularly participating in basketball trainings for at least one year. Postural disorder is defined as an irregularity in posture of the spine and feet, and it is assessed by visual methods from the front, side and rear side of the body. The prevalence of spinal deformities in our group was 53.13%. The boys had a significantly higher prevalence than girls, 65.1% compared to 28.57% (p=0.006). There was no significant difference in prevalence of spine deformities between children of different ages. The prevalence of feet deformities was 64.06%. There was a statistically significant difference between the sexes, where boys had a significantly greater prevalence of the feet deformities than girls, 83.7% compared to 23.81% (p=0.001). Flat feet were the most common in 10 year old children (85.71%). In conclusion, it can be said that despite regular participation in basketball training, subjects in this study have high prevalence of deformities; especially boys who stand out with the high prevalence of flat feet.

    Full Text Available OBJECTIVE: To investigate associations of family-related factors with children's breakfast consumption and BMI-z-score and to examine whether children's breakfast consumption mediates associations between family-related factors and children's BMI-z-score. SUBJECTS: Ten- to twelve-year-old children (n = 6374; mean age = 11.6 ± 0.7 years, 53.2% girls, mean BMI-z-score = 0.4 ± 1.2 and one of their parents (n = 6374; mean age = 41.4 ± 5.3 years, 82.7% female, mean BMI = 24.5 ± 4.2 kg/m(2 were recruited from schools in eight European countries (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia, Spain, and Switzerland. The children self-reported their breakfast frequency per week. The body weight and height of the children were objectively measured. The parents responded to items on family factors related to breakfast (automaticity, availability, encouragement, paying attention, permissiveness, negotiating, communicating health beliefs, parental self-efficacy to address children's nagging, praising, and family breakfast frequency. Mediation analyses were performed using multi-level regression analyses (child-school-country. RESULTS: Three of the eleven family-related variables were significantly associated with children's BMI-z-score. The family breakfast frequency was negatively associated with the BMI-z-score; permissiveness concerning skipping breakfast and negotiating about breakfast were positively associated with the BMI-z-score. Children's breakfast consumption was found to be a mediator of the two associations. All family-related variables except for negotiating, praising and communicating health beliefs, were significantly associated with children's breakfast consumption. CONCLUSIONS: Future breakfast promotion and obesity prevention interventions should focus on family-related factors including the physical home environment and parenting practices. Nevertheless, more longitudinal research and intervention studies to support these findings between family-related factors and both children's breakfast consumption and BMI-z-score are needed.

    We present 2 cases of the slow-fast form of AVNRT with initially narrow QRS complexes followed by sudden unexpected transition to persistently wide QRS complexes due to aberrant intraventricular conduction. Introduction of a properly timed extrastimulus in one case and critical oscillations in cycle length due to short-long coupling in the second case set the stage for the initial bundle branch block. However, persistence of the aberrancy pattern once the initial event abated was maintained by the "linking" phenomenon. Delayed, retrograde concealed activation from the contralateral bundle branch perpetuated the initial bundle branch block. PMID:23840106

    Full Text Available Biomedical literature is an essential source of biomedical evidence. To translate the evidence for biomedicine study, researchers often need to carefully read multiple articles about specific biomedical issues. These articles thus need to be highly related to each other. They should share similar core contents, including research goals, methods, and findings. However, given an article r, it is challenging for search engines to retrieve highly related articles for r. In this paper, we present a technique PBC (Passage-based Bibliographic Coupling that estimates inter-article similarity by seamlessly integrating bibliographic coupling with the information collected from context passages around important out-link citations (references in each article. Empirical evaluation shows that PBC can significantly improve the retrieval of those articles that biomedical experts believe to be highly related to specific articles about gene-disease associations. PBC can thus be used to improve search engines in retrieving the highly related articles for any given article r, even when r is cited by very few (or even no articles. The contribution is essential for those researchers and text mining systems that aim at cross-validating the evidence about specific gene-disease associations.

    The current study explored subtle dehumanization-the denial of full humanness-in children, using distinctions of forms (i.e., animalistic vs. mechanistic) and social targets (i.e., friends vs. non-friends). In addition, the link between dehumanization and moral disengagement in bullying and victimization was investigated. Participants were 800 children (7-12 years old) from third to fifth grade classrooms. Subtle animalistic and mechanistic dehumanization toward friends and non-friends were measured with the new Juvenile Dehumanization Measure. Results showed that animalistic dehumanization was more common than mechanistic dehumanization and that non-friends were dehumanized more than friends. The highest levels of dehumanization were found in animalistic form toward non-friends and the lowest levels in mechanistic form toward friends. Both moral disengagement and animalistic dehumanization toward friends were positively associated with bullying. However, moral disengagement was negatively associated with victimization, whereas both animalistic and mechanistic dehumanization toward non-friends were positively associated with victimization. The current findings indicate that children are able to distinguish different forms and targets of dehumanization and that dehumanization plays a distinct role from moral disengagement in bullying and victimization.

    Full Text Available The purpose of this paper is to provides general information about avian influenza (bird flu and specific information about one type of bird flu, called avian influenza A (H5N1, that has caused infections in birds in Asia and Europe and in human in Asia. The main materials in this report are based on the World Health Organization (WHO , world organization for animal health (OIE , food and agriculture organization of the united nations (FAO information and recommendations and review of the published literature about avian influenza. Since December 2003, highly pathogenic H5N1 avian influenza viruses have swept through poultry populations across Asia and parts of Europe. The outbreaks are historically unprecedented in scale and geographical spread. Their economic impact on the agricultural sector of the affected countries has been large. Human cases, with an overall fatality rate around 50%, have also been reported and almost all human infections can be linked to contact with infected poultry. Influenza viruses are genetically unstable and their behaviour cannot be predicted so the risk of further human cases persists. The human health implications have now gained importance, both for illness and fatalities that have occurred following natural infection with avian viruses, and for the potential of generating a re-assortant virus that could give rise to the next human influenza pandemic.

  4. Finding and Recommending Scholarly Articles

    Kurtz, Michael J.; Henneken, Edwin A.

    2014-05-01

    The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

    The Appreciation of RMB, the Behavior of Firms and the Export Trade: A Case Study Based on the Enterprise Data of a Large Specimen between 2005 and 2009 In this article, we have constructed a simplified dynamic discrete choice model to analyze, within the framework of the maximization of profit, the two-stage decision of firm' s export behavior and the effect of the exchange rate. We have, by the means of the specimen data on China' s industrial enterprises between 2005 and 2009 and by the use of Heckman selection model, evaluated the general impact of the appreciation of RMB (AORMB) on the export trade and the structural impact. The results of our study indicate that the AORMB has generated significant negative shock to firm ' s export through extensive margins and intensive margins. Meanwhile, the difference in operation strategy of heteroge- neous firms has resulted in the fact that the AORMB can hardly achieve the expected purpose of the survival of the fit- test; instead it has interrupted the optimization of the adjustment in the optimization of the structure of the main body of the export trade. The AORMB has, in a certain degree, driven the industry structure of export to develop to a higher phase. However, such positive effects have mainly rooted in the contribution of foreign-funded enterprises, but this pos- itive role has restricted the growth space of the local enterprises in the advanced manufacturing industry. Under the cir- cumstance of high uncertainty in foreign and domestic economy, in order to guarantee the steady transition of the eco- nomic transition, the AORMB should be slowed for the time being, and other more pertinent measures should be adopt- ed to drive the upgrade of the export trade and the adjustment of economic structure.

  7. Data Sharing Effect on Article Citation Rate in Paleoceanography

    Sears, J. R.

    2011-12-01

    The validation of scientific results requires reproducible methods and data. Often, however, data sets supporting research articles are not openly accessible and interlinked. This analysis tests whether open sharing and linking of supporting data through the PANGAEA° data library measurably increases the citation rate of articles published between 1993 and 2010 in the journal Paleoceanography as reported in the Thomson Reuters Web of Science database. The 12.85% (171) of articles with publicly available supporting data sets received 19.94% (8,056) of the aggregate citations (40,409). Publicly available data were thus significantly (p=0.007, 95% confidence interval) associated with about 35% more citations per article than the average of all articles sampled over the 18-year study period (1,331), and the increase is fairly consistent over time (14 of 18 years). This relationship between openly available, curated data and increased citation rate may incentivize researchers to share their data.

      Currently, there has been a growing interest in the study of academic writing; focusing on the structural organization of academic text or specific linguistic features. However, very few studies have been done on the structural organization of the Methods and the linguistic features link to each move. Thus, the purpose of this study is to identify rhetorical structure of the Methods of agricultural science research articles and to explore the linguistic features linked to each identified move, by analyzing thirty research articles based on Kanoksilapatham’s (2005) framework. Altogether, five moves were found in the Methods, showing that rhetorical structure of Methods in agricultural science has its own format. The moves and linguistic features realizing rhetorical functions may help novice researchers or learners write the Methods of science research articles effectively and professionally

Iran J Child Neurol. 2014 Summer;8(3: 1-5.AbstractObjectiveInfantile spasm (IS is a convulsive disease characterized by brief, symmetric axial muscle contraction (neck, trunk, and/or extremities. IS is a type of seizure that was first described by West in 1841, who witnessed the seizure in his own son. West’s syndrome refers to the classic triad of spasms, characteristic EEG, and neurodevelopmental regression. Most cases involve flexors and extensors,but either of the types may be involved independently.IS, as its name implies, most often occurs during the first year of life with an incidence of approximately 1 per 2000-4000 live births. Most, but not all, patients with this disorder have severe EEG abnormalities; this pattern was originallyreferred to as hypsarrhythmia by Gibbs and Gibbs. Cases with known etiology or signs of brain damage are considered as symptomatic. The Overall prognosis of the disease is poor. Peak onset age of the epileptic syndrome is 3 to 7 months, which mainly occurs before 2 years of age in 93% of patients.

    Writing a good quality scientific article takes experience and skill. I propose 'Ten Tips' that may help to improve the quality of manuscripts for scholarly journals. It is advisable to draft first version of manuscript and revise it repeatedly for consistency and accuracy of the writing. During the drafting and revising the following tips can be considered: 1) focus on design to have proper content, conclusion, points compliant with scope of the target journal, appropriate authors and contributors list, and relevant references from widely visible sources; 2) format the manuscript in accordance with instructions to authors of the target journal; 3) ensure consistency and logical flow of ideas and scientific facts; 4) provide scientific confidence; 5) make your story interesting for your readers; 6) write up short, simple and attractive sentences; 7) bear in mind that properly composed and reflective titles increase chances of attracting more readers; 8) do not forget that well-structured and readable abstracts improve citability of your publications; 9) when revising adhere to the rule of 'First and Last' - open your text with topic paragraph and close it with resolution paragraph; 10) use connecting words linking sentences within a paragraph by repeating relevant keywords.

The combination of Linked Data with a search engine can help to improve ad-hoc retrieval. This article presents and documents the process of building a search index for the Solr search engine from bibliographic records published as linked open data.

  19. Why does attention to web articles fall with time?

    CERN Document Server

    Simkin, M V

    2012-01-01

    We analyze access statistics for a few dozen blog entries for a period of several years. Access rate falls as an inverse power of time passed since publication. The power law holds for periods up to thousand days. The exponents are different for different blogs and are distributed between 1 and 3. Decay of attention to aging web articles has been reported before and two explanations were proposed. One explanation introduced some decaying with time novelty factor. Another used some intricate theory of human dynamics. We argue that the decay of attention to a web article is simply caused by the link to it first dropping down the list of links on the website's front page, disappearing from the front page and subsequent movement further into background.

  20. Toward an interactive article: integrating journals and biological databases

    2011-05-01

    Full Text Available Abstract Background Journal articles and databases are two major modes of communication in the biological sciences, and thus integrating these critical resources is of urgent importance to increase the pace of discovery. Projects focused on bridging the gap between journals and databases have been on the rise over the last five years and have resulted in the development of automated tools that can recognize entities within a document and link those entities to a relevant database. Unfortunately, automated tools cannot resolve ambiguities that arise from one term being used to signify entities that are quite distinct from one another. Instead, resolving these ambiguities requires some manual oversight. Finding the right balance between the speed and portability of automation and the accuracy and flexibility of manual effort is a crucial goal to making text markup a successful venture. Results We have established a journal article mark-up pipeline that links GENETICS journal articles and the model organism database (MOD WormBase. This pipeline uses a lexicon built with entities from the database as a first step. The entity markup pipeline results in links from over nine classes of objects including genes, proteins, alleles, phenotypes and anatomical terms. New entities and ambiguities are discovered and resolved by a database curator through a manual quality control (QC step, along with help from authors via a web form that is provided to them by the journal. New entities discovered through this pipeline are immediately sent to an appropriate curator at the database. Ambiguous entities that do not automatically resolve to one link are resolved by hand ensuring an accurate link. This pipeline has been extended to other databases, namely Saccharomyces Genome Database (SGD and FlyBase, and has been implemented in marking up a paper with links to multiple databases. Conclusions Our semi-automated pipeline hyperlinks articles published in GENETICS to

    The author presents two tricks to accelerate depth-first search algorithms for a class of combinatorial puzzle problems, such as tiling a tray by a fixed set of polyominoes. The first trick is to implement each assumption of the search with reversible local operations on doubly linked lists. By this trick, every step of the search affects the data incrementally. The second trick is to add a ghost square that represents the identity of each polyomino. Thus puts the rule that each polyomino be used once on the same footing as the rule that each square be covered once. The coding simplifies to a more abstract form which is equivalent to 0-1 integer programming. More significantly for the total computation time, the search can naturally switch between placing a fixed polyomino or covering a fixed square at different stages, according to a combined heuristic. Finally the author reports excellent performance for his algorithm for some familiar puzzles. These include tiling a hexagon by 19 hexiamonds and the N queen...

    Review article or literature review actually is the simplest form of writing compared to a case report or study report. The writing process begins at pointing out topics to be written and informed to readers. The next step after the topic has been selected is to find literatures related to the article review writing. Principally, article writing plays an essential part in a doctor's life, whether as a specialist or consultant. And the most important is the desire to publish the article review.

  7. Measuring the Interestingness of News Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

  14. Articles on elderly in Serbian medical journals

    2009-01-01

    Full Text Available Introduction Population aging is a feature of all countries in the world. According to statistics, the Republic of Serbia is one of the countries with the majority of the elderly. Taking this into account, are articles on the elderly well represented in domestic medical journals? Objective The aim of the paper was to determine whether there was a sufficient number of articles on the elderly in domestic medical journals. Methods The articles on the elderly were searched using search engines in domestic and foreign medical journals for the last 5 years compared with the number of articles on children in the same publications for the same period. Results In the Serbian Citation Index, 11 articles on the topic of the elderly, and 487 on children were registered. In Srpski arhiv za celokupno lekarstvo, there was registered only one article on the topic of the elderly, and 30 on children. In Vojnosanitetski pregled, 2 articles on the elderly and 13 on children were registered (p<0001. For the last five years, in the New England Journal of Medicine, there were 593 articles on the elderly and 759 articles on children; in the JAMA, there were 63 articles on the elderly and 303 articles on children; and in The Lancet, in the last five years, 46 articles on the elderly and 148 articles on children were published. Conclusion The themes of the elderly were rarely represented in Serbian medical journals. This has reduced the interest of physicians in medical problems of this growing population of patients and further sent them away from making standards in the diagnosis and treatment of the elderly.

    This study analyzed the psychological adjustment of parents of children and adolescents with type 1 diabetes (T1D) and examined whether family cohesion and parental adjustment were connected through the perceived impact of this condition on family functioning, as well as whether these links varied according to the child's age. In total, 104 parents of children (8-12 years old) and adolescents (13-18 years old) with T1D and 142 parents of healthy children and adolescents completed self-report measures of family cohesion, parental stress, quality of life (QOL), anxious and depressive symptoms, and perceived impact of chronic illness. The results indicated that the parents of children and adolescents with T1D were more anxious and perceived less family cohesion than the parents of healthy children and adolescents. No significant differences were found on depressive symptoms, QOL, and parental stress. The hypothesized moderated mediation model showed that parents who perceived their family environments as more supportive and caring tended to evaluate the impact of T1D on their families less negatively; in turn, this perception was associated with better QOL and less parental stress and anxious and depressive symptoms. These associations were independent of the children's age. Based on a risk and resistance framework, this study highlighted the relevance of the perceived impact of T1D on the family as a mechanism explaining the link between cohesion and parental adjustment. Family-centered interventions that help parents better cope with the demands of T1D and help family members be more supportive of each other seem to be particularly useful in this context.

    Full Text Available Objetivo. Identificar los factores de exposición asociados a las concentraciones de plomo en niños de escuelas primarias públicas y privadas de la ciudad de México. Material y métodos. Se realizó un estudio transversal en 340 niños que asistían a la escuela primaria. Las escuelas se seleccionaron por conveniencia y los niños en forma aleatoria. Se aplicó un cuestionario y se tomaron muestras de sangre venosa. Los niveles de plomo se determinaron por espectrofotometría de absorción atómica. Se compararon medias mediante la prueba t de Student-Fisher y ANDEVA; y para el análisis multivariado, regresión lineal múltiple. Debido a que los niveles de plomo no seguían una distribución normal, se transformó con logaritmo neperiano, con la que se trabajó en todo el análisis estadístico. Resultados. Las medias geométricas para escuelas privadas y públicas fueron: MG=8.76 µg/dl, IC95%=9.1-10.5; MG=11.5 µg/dl, IC95%=9.4-13.5, respectivamente. Los niveles de plomo son más elevados en los niños que asisten a la escuela pública y que presentan las siguientes características: ser varones, tener entre seis y ocho años de edad y cursar el primer o segundo grado de primaria; las madres de estos niños son profesionistas; en sus hogares se utiliza la cerámica vidriada y cerca de sus domicilios existen diferentes tipos de talleres contaminantes con plomo. Conclusiones. Los factores de exposición que predicen las concentraciones de plomo en sangre son: tener entre seis y ocho años de edad, la ocupación de la madre, la utilización de cerámica vidriada, la cercanía de diferentes tipos de talleres contaminantes con plomo a los domicilios y cursar el segundo año de primaria.Objective. To identify exposure factors contributing to lead poisoning in school children from Mexico City. Material and methods. Cross-sectional study of 340 children. A convenience sample of schools and a random sample of children were selected. A questionnaire was filled out and venous blood samples were taken. Lead levels were measured by atomic absorption spectrophotometry. Statistical analysis consisted of comparison of means using Student’s t test and ANOVA. Multiple linear regression was used for multivariate analysis. Logarithmic transformation of lead blood levels were used to account for their non-normal distribution. Results. Geometric means for private and public schools were: GM=8.76 µg/dl, 95% CI=9.1-10.5; GM=11.5 µg/dl, 95% CI=9.4-13.5. Lead levels were higher among children from public schools who are male, between 6 and 8 years of age, in first and second grade, whose mothers have a profession, who use glazed earthenware utensils, and who live near glazed earthenware shops or factories. Conclusions. Exposure predictors of lead blood levels are: being between 6 and 8 years of age, having a professional mother, using glazed earthenware utensils, living near glazed earthenware shops or factories, and studying the second grade of elementary school.

    Full Text Available Introduction & aims: The identification of determinants of childhood overweight is crucial to early diagnosis and prevention. The aim of this study was to assess perinatal and parental related risk factors concerning children for having excessive body weight. Methods: Cross-sectional study involving 3,101 children participating in the programme "Alimenta su salud" conducted in Castilla-La Mancha (Spain. Anthropometric and sociodemographic data were obtained from a general questionnaire. Analysed factors as potential predictors of childhood overweight were sex, age, birth weight, infant feeding, number of siblings, as well as parental marital status, educational level and obesity. Prevalence of overweight stratified by potential determinants was assessed. Univariate and multivariate logistic regression analyses were used to examine the associations between variables and the likelihood of being overweight. Results: The overweight prevalence (including obesity was 30.3% in boys and 28.3% in girls, according to the IOTF criteria. Higher rates in younger subjects and some gender differences were observed. Parental obesity was the most important predictive variable for childhood overweight in both sexes and birth weight over 3,500 g in girls (OR 1.8, 95% CI 1.3-2.3. Having one or more siblings (OR 0.7, 95% CI 0.5-0.9 and higher paternal education (OR 0.8, 95% CI 0.6-0.9 in boys, and older age in girls (OR 0.7, 95% CI 0.5-.09, resulted protective factors against childhood overweight. No independent effects of marital status, maternal education and infant feeding patterns on childhood excess weight were identified. Conclusions: Perinatal and parental factors could contribute to predict the risk of being overweight/obese in children aged 6 to 12 years, which should be considered when formulating obesity prevention and intervention strategies, stressing the importance of targeting obese parents with young children.Objetivos: Identificar los determinantes del sobrepeso infantil resulta clave para la prevención y diagnóstico precoz. El objetivo de este trabajo fue evaluar factores perinatales y paternos asociados al riesgo de sobrepeso y obesidad infantil. Métodos: Estudio transversal en 3.101 niños participantes en el programa "Alimenta su salud" llevado a cabo en Castilla-La Mancha. Los datos antropométricos y sociodemográficos fueron obtenidos mediante la aplicación de una encuesta. Las variables consideradas como potenciales predictores de sobrepeso infantil fueron sexo, edad, peso al nacer, lactancia recibida y número de hermanos de los niños, así como estado civil, nivel educativo y obesidad en los padres. El estudio analizó la frecuencia de sobrepeso estratificada por los potenciales factores de riesgo y se empleó regresión lineal univariante y multivariante para estudiar la asociación entre las variables candidatas y la probabilidad de tener sobrepeso. Resultados: La prevalencia de sobrecarga ponderal (incluyendo obesidad fue del 30,3% en los varones y el 28,3% en las niñas, de acuerdo con los criterios de IOTF. Los mayores porcentajes de exceso de peso se observaron en edades más tempranas con diferencias en función del sexo. La obesidad en los padres resultó el factor de riesgo más importante de sobrepeso y obesidad infantil en ambos sexos y en las chicas además, un peso al nacer mayor de 3.500 g (OR 1,8 IC 95% de 1,3-2,3. Por otro lado, tener uno o más hermanos (OR 0,7 IC 95% de 0,5-0,9 y un mayor nivel educativo paterno (OR 0,8 IC 95% de 0,6-0,9 resultaron factores protectores frente al sobrepeso infantil en chicos. La probabilidad de tener sobrepeso fue menor en las chicas de mayor edad (OR 0,7 IC 95% de 0,5 a 0,9. No se identificó un efecto independiente del estado civil, la educación materna o la lactancia recibida asociado al riesgo de sobrepeso infantil. Conclusiones: Ciertos factores perinatales y paternos pueden contribuir a predecir el riesgo de sobrepeso/obesidad en niños de 6 a 12 años, por lo que deberían ser considerados en el diseño de estrategias orientadas a la prevención e intervención precoz, haciendo hincapié en aquellas dirigidas a los padres obesos con niños pequeños.

Setenta e oito crianças participaram do experimento em que foram manipulados os fatores idade, posição espacial, similaridade visual e cor dos estímulos memorizados. Os resultados mostraram que todos os fatores principais alcançaram significância estatística. As crianças mais velhas tiveram uma freqüência de acertos maior que as crianças mais novas. Os estímulos dos conjuntos com similaridade baixa foram mais bem recordados que os estímulos com similaridade alta. A taxa de recordação foi melhor nas provas em que as letras de um conjunto foram todas apresentadas com a mesma cor, assim como a porcentagem de respostas corretas variou de forma significativa em função da posição espacial dos estímulos. Os resultados foram interpretados de acordo com modelos que enfatizam aspectos do desenvolvimento de estratégias cognitivas ao longo do desenvolvimento humano, especialmente o modelo de memória de trabalho.This study aimed to evaluate the mechanisms of visual-spatial memory in children. Seventy eight children took part in an experiment with four factors: children's age, stimuli spatial position, stimuli visual similarity, stimuli set color. The results have shown that all main factors are statistically meaningful. The oldest children presented a better performance than the youngest ones. Stimuli set formed by low similarity letters were better recollected than the stimuli set formed by high similarity letters. The recall of the spatial position of letters was better in trials where the letters of a set were presented in the same color. The percentage of correct recall changed meaningfully as a function of the spatial position in which the target had been presented. The results were interpreted according to models that emphasize aspects of development of cognitive strategies along with the human development, especially the working memory model.

    The retraction of an original article aims to ensure that readers are alerted to the fact that the findings are not trustworthy. However, the present research suggests that individuals still believe in the findings of an article even though they were later told that the data were fabricated and that the article was retracted. Participants in a debriefing condition and a no-debriefing condition learned about the scientific finding of an empirical article, whereas participants in a control condition did not. Afterward, participants in the debriefing condition were told that the article had been retracted because of fabricated data. Results showed that participants in the debriefing condition were less likely to believe in the findings than participants in the no-debriefing condition but were more likely to believe in the findings than participants in the control condition, suggesting that individuals do adjust their beliefs in the perceived truth of a scientific finding after debriefing-but insufficiently. Mediational analyses revealed that the availability of generated causal arguments underlies belief perseverance. These results suggest that a retraction note of an empirical article in a scientific journal is not sufficient to ensure that readers of the original article no longer believe in the article's conclusions.

    Full Text Available This article aims to analyze motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations of scholarly journal articles are good indicators for the societal impact of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging published between 01/01/2012 to 18/06/2014 were subjected to content analysis. An existing categorization scheme was used and modified inductively. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty-one (22.68% of all journals cited were from the category of social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy-five percent of all journals were referenced only once. The average age of articles cited was 5.8 years. The most frequent (38, 12.67% motivation was to ‘neutrally presenting details of a study’. Overall, social science blogs were rather subject-oriented than article oriented. This means a considerable number of blog posts were not driven simply by writing about an article, instead bloggers tend to write about their subject of interest and use references to support their argument. The study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact.

    Duchane, D.V.

    1981-05-29

    Super-smooth rounded or formed articles made of thermoplastic materials including various poly(methyl methacrylate) or acrylonitrile-butadiene-styrene copolymers are produced by immersing the articles into a bath, the composition of which is slowly changed with time. The starting composition of the bath is made up of at least one solvent for the polymer and a diluent made up of at least one nonsolvent for the polymer and optional materials which are soluble in the bath. The resulting extremely smooth articles are useful as mandrels for laser fusion and should be useful for a wide variety of other purposes, for example lenses.

    This exploratory study investigates the bipartite network of articles linked by common editors in Wikipedia, 'The Free Encyclopedia that Anyone Can Edit'. We use the articles in the categories (to depth three) of Physics and Philosophy and extract and focus on significant editors (at least 7 or 10...... edits per each article). We construct a bipartite network, and from it, overlapping cliques of densely connected articles and editors. We cluster these densely connected cliques into larger modules to study examples of larger groups that display how volunteer editors flock around articles driven...

  14. Discovering opinion leaders for medical topics using news articles

    2012-03-01

    Full Text Available Abstract Background Rapid identification of subject experts for medical topics helps in improving the implementation of discoveries by speeding the time to market drugs and aiding in clinical trial recruitment, etc. Identifying such people who influence opinion through social network analysis is gaining prominence. In this work, we explore how to combine named entity recognition from unstructured news articles with social network analysis to discover opinion leaders for a given medical topic. Methods We employed a Conditional Random Field algorithm to extract three categories of entities from health-related new articles: Person, Organization and Location. We used the latter two to disambiguate polysemy and synonymy for the person names, used simple rules to identify the subject experts, and then applied social network analysis techniques to discover the opinion leaders among them based on their media presence. A network was created by linking each pair of subject experts who are mentioned together in an article. The social network analysis metrics (including centrality metrics such as Betweenness, Closeness, Degree and Eigenvector are used for ranking the subject experts based on their power in information flow. Results We extracted 734,204 person mentions from 147,528 news articles related to obesity from January 1, 2007 through July 22, 2010. Of these, 147,879 mentions have been marked as subject experts. The F-score of extracting person names is 88.5%. More than 80% of the subject experts who rank among top 20 in at least one of the metrics could be considered as opinion leaders in obesity. Conclusion The analysis of the network of subject experts with media presence revealed that an opinion leader might have fewer mentions in the news articles, but a high network centrality measure and vice-versa. Betweenness, Closeness and Degree centrality measures were shown to supplement frequency counts in the task of finding subject experts. Further

    Do you have a poor-performing employee on your medical practice team? If so, you're not alone. Unfortunately, this is a problem that many medical practice managers face. This article describes the best strategies for managing your team's weakest link. It explores common yet very difficult circumstances that cause low employee performance and that test the patience, heart, and skills of a practice manager. It guides readers through a process of self-discovery to determine whether their negative biases or grudges may be causing employees to perform poorly. It suggests several possible other reasons for weak employee performance, including problems with the job, practice, leadership, communication, and fit between the employee and the job. This article also suggests the best strategy for communicating concerns about performance to the weakest-link employee. It offers guidance to practice managers about protecting their time and energy when handling a poor performer. It provides a simple formula for calculating the cost of a low-performing employee, 10 possible personal reasons for the employee's poor work performance, specific questions to ask to uncover the reasons for poor performance, and an eight-rule strategy for confronting poor performance effectively. Finally, this article offers practice managers a practical strategy for handling resistance from their weakest link, illustrated with a sample dialogue.

    2013-01-01

    Predicting the popularity or access usage of an article has the potential to improve the quality of PubMed searches. We can model the click trend of each article as its access changes over time by mining the PubMed query logs, which contain the previous access history for all articles. In this article, we examine the access patterns produced by PubMed users in two years (July 2009 to July 2011). We explore the time series of accesses for each article in the query logs, model the trends with regression approaches, and subsequently use the models for prediction. We show that the click trends of PubMed articles are best fitted with a log-normal regression model. This model allows the number of accesses an article receives and the time since it first becomes available in PubMed to be related via quadratic and logistic functions, with the model parameters to be estimated via maximum likelihood. Our experiments predicting the number of accesses for an article based on its past usage demonstrate that the mean absolute error and mean absolute percentage error of our model are 4.0% and 8.1% lower than the power-law regression model, respectively. The log-normal distribution is also shown to perform significantly better than a previous prediction method based on a human memory theory in cognitive science. This work warrants further investigation on the utility of such a log-normal regression approach towards improving information access in PubMed.

    Full Text Available In Nicaragua levels Linking state, university and business are low, Nicaraguan universities have initiated communication strategies with the state and the private sector. The idiosyncrasies of its citizens favor this link. The entailment policies formalize the communications and information networks. Universities have a key role in building models and organizations that provide alternatives to economic development. Linking the university with the environment, generating virtuous circles, where companies achieve greater competitiveness, the state, higher taxes and public stability, universities generate new knowledge. This article analyzes the strategies linking U-E- E that can be applied in Nicaragua, to strengthen and achieve positive developments in the country.

  2. Tracking Multiple Topics for Finding Interesting Articles

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    of JCE in the mail each month, and I expect you do too. I can glance at the cover to get an overview of an issue's content, and I usually am enticed inside by intriguing cover art. I can scan the table of contents to find articles I want to read, or I can just browse through the issue to see what looks interesting. Usually the editors have juxtaposed related articles so that I often find a small treasure trove. The printed Journal is quite portable and can be read in a car or airplane. It will last a long time, and until the paper deteriorates, I will never have a problem reading back issues. I have almost every issue from the first day I subscribed and have even added some older ones from collections of retired colleagues who no longer had shelf space for them. I certainly would not want to give up my printed copies, and I want to keep getting them. I find that JCE Online provides a different kind of resource that is equally valuable. It contains more information, and information that is more appropriate in electronic form. It links related ideas into a much more complex web of information than is possible in print. And it opens pathways to lots of information that is not part of JCE but resides elsewhere. Using this issue as an example, let's take a tour of what JCE Online can do. Point your Web browser to http://jchemed.chem.wisc.edu Click on Journal and then on Current Issue (unless September 1999 is no longer the current issue, in which case you will find it in Past Issues). In the table of contents, find the article "UV Catalysis, Cyanotype Photography, and Sunscreens". Click on the title. When the abstract appears, click on Full Text (PDF) to see the article, just as it appears on page 1199 in this issue. When you are prompted, enter the name and subscriber number from your address label. At the end of the article you will find that supplementary materials are available (including a procedure for testing sunscreens) and you can click on the link to view them

  4. Mining Related Articles for Automatic Journal Cataloging

    2016-06-01

    Full Text Available Purpose: This paper is an investigation of the effectiveness of the method of clustering biomedical journals through mining the content similarity of journal articles. Design/methodology/approach: 3,265 journals in PubMed are analyzed based on article content similarity and Web usage, respectively. Comparisons of the two analysis approaches and a citation-based approach are given. Findings: Our results suggest that article content similarity is useful for clustering biomedical journals, and the content-similarity-based journal clustering method is more robust and less subject to human factors compared with the usage-based approach and the citation-based approach. Research limitations: Our paper currently focuses on clustering journals in the biomedical domain because there are a large volume of freely available resources such as PubMed and MeSH in this field. Further investigation is needed to improve this approach to fit journals in other domains. Practical implications: Our results show that it is feasible to catalog biomedical journals by mining the article content similarity. This work is also significant in serving practical needs in research portfolio analysis. Originality/value: To the best of our knowledge, we are among the first to report on clustering journals in the biomedical field through mining the article content similarity. This method can be integrated with existing approaches to create a new paradigm for future studies of journal clustering.

    Scientific research and the publication of the results of the studies go hand in hand. Exquisite research methods can only be adequately reflected in formal publication with the optimum structure. To ensure the success of this process, it is necessary to follow orderly steps, including selecting the journal in which to publish and following the instructions to authors strictly as well as the guidelines elaborated by diverse societies of editors and other institutions. It is also necessary to structure the contents of the article in a logical and attractive way and to use an accurate, clear, and concise style of language. Although not all the authors are directly involved in the actual writing, elaborating a scientific article is a collective undertaking that does not finish until the article is published. This article provides practical advice about formal and not-so-formal details to take into account when writing a scientific article as well as references that will help readers find more information in greater detail.

    2006-12-01

    Full Text Available Purpose: Shared services is a viable business model that can be used by organisations to reduce costs and enhance efficiency and effectiveness in the organisation. The purpose of this trilogy of articles is to introduce shared services as a business model, and how to efficiently and effectively manage a shared services business unit. The purpose of the first article in the trilogy, introduces shared services as a business model, defines what shared services is, the transformation required to successfully implement a shared services business model, as well as the benefits that can be derived from implementing a shared services business model. Methodology: A comprehensive literature study was conducted in order to: - Define and describe shared services as a business model, - Compare shared services with centralisation and de-centralisation, - Determine and describe the transformation required to successfully implement shared services. Findings: In the article, a framework is generated to help organisations understand the business concept of shared services. This work has further potential: when applied correctly, there are both tangible and intangible benefits that can be accrued above cost savings. Implications: The findings of this article are important for organisations that are in the process of implementing or have implemented shared services, as it will assist the organisation in determining if shared services is the correct business model for them to implement. Value: This article provides an understanding of shared services and the business environment required to successfully implement a shared services business model. Value created by a shared services business model is further enhanced once the organisation has embarked on the successful implementation of a shared services business model, which is the primary objective of the second article, Implementation and continuous evolution in shared services.

    2016-06-10

    Introduction Altmetrics is a new and emerging scholarly tool that measures online attention surrounding journal articles. Altmetric data resources include: policy documents, news outlets, blogs, online reference managers (eg Mendeley and CiteULike), post-publication peer-review forums (eg PubPeer and Publons), social media (eg Twitter, Facebook, Weibo, Google(+), Pinterest, Reddit), Wikipedia, sites running Stack Exchange (Q&A), and reviews on F1000 and YouTube.Methods To identify the top 50 dental articles in 2014, PubMed was searched using the following query "("2014/1/1"[PDAT]:"2014/12/31"[PDAT]) and jsubsetd[text]" in December, 2015. Consequently, all PubMed records were extracted and sent to Altmetric LLP (London, UK) as a CSV file for examination. Data were analysed by Microsoft Office Excel 2010 using descriptive statistics and charts.Results Using PubMed searches,15,132 dental articles were found in 2014. The mean Altmetric score of 50 top dental articles in 2014 was 69.5 ± 73.3 (95% CI: -74.14 to 213.14). The British Dental Journal (48%) and Journal of Dental Research (16%) had the maximum number of top articles. Twitter (67.13%), Mendeley (15.89%) and news outlets (10.92%) were the most popular altmetric data resources.Discussion Altmetrics are intended to supplement bibliometrics, not replace them. Altmetrics is a fresh and emerging arena for the dental research community. We believe that dental clinical practitioners, research scientists, research directors and journal editors must pay more attention to altmetrics as a new and rapid tool to measure the social impact of scholarly articles.

    Full Text Available - It is an emerging challenge for data mining is the problem of mining richly structures datasets, where the objects are linked in some way. Links among the objects may demonstrate certain patterns, which can be helpful for many data mining tasks and are usually hard to capture with traditional statistical models. Many datasets of interest today are best described as a linked collection of interrelated objects. These may represent homogeneous networks, in which there is a single-object type and link type (eg. people connected by friendship links, or the WWW, a collection of linked web pages or richer, heterogeneous networks, in which there may be multiple object and link types (and possibly other semantic information. Examples of heterogeneous networks include those in medical domains describing patients, diseases, treatments and contacts, or in bibliographic domains describing publications, authors, and venues. Link mining refers to data mining techniques that explicitly consider these links when building predictive or descriptive models of the linked data. Commonly addressed link mining tasks include object ranking, group detection, collective classification, link prediction and subgraph discovery. This is an exciting and rapidly expanding area. In this article we review some of the common emerging themes and discuss ongoing link mining challenges; open issues and suggest ideas that could be opportunities for solutions. The most conclusion of this article is that providing an idea to usage link mining techniques from link mining to help to construct the Semantic Web.

    We describe a physical and logical layout analysis algorithm, which is applied to segment and label online medical journal articles (regular HTML and PDF-Converted-HTML files). For these articles, the geometric layout of the Web page is the most important cue for physical layout analysis. The key to physical layout analysis is then to render the HTML file in a Web browser, so that the visual information in zones (composed of one or a set of HTML DOM nodes), especially their relative position, can be utilized. The recursive X-Y cut algorithm is adopted to construct a hierarchical zone tree structure. In logical layout analysis, both geometric and linguistic features are used. The HTML documents are modeled by a Hidden Markov Model with 16 states, and the Viterbi algorithm is then used to find the optimal label sequence, concluding the logical layout analysis.

    2003-01-01

    If we examine the text of scientific articles it is clear that there is a generally accepted way of writing them. Scientific prose in English stereotypically uses the third person, the passive tense, complex terminology, and various footnoting and referencing systems. Scientific prose is not known for discursive anecdotes, humour, pictures, colour, bizarre typography or exclamation marks! Often the written text appears quite impersonal-the human element is removed.

    Reyes, Humberto; Palma, Joaquín; Andresen, Max

    2007-04-01

    Authors of clinical articles have similar motivations and rules than authors in other scientific fields. In addition, medical research must obey specific ethical rules that apply to studies involving human subjects, including biological samples, tissues, cellular or sub cellular samples obtained from them. When submitting their reports for publication, authors must declare that they have followed such ethical rules and also should declare any possible conflict of interest that may have arisen. External peer reviewers and the editors should also conform to limitations by eventual conflicts of interest. Authors should respect specific ethical norms that apply to the process of submitting, publishing and reproducing their manuscripts. In recent years, the editors of Revista Médica de Chile have become aware of five instances of misconduct committed by authors of articles submitted or already published. Four correspond to redundant publications and one exhibits overt plagiarism in the text and syntax. Appropriate actions have been taken following recommendations published by the International Committee of Medical Journal Editors, the World Association of Medical Editors and other groups. The present article stresses that authors and their sponsoring institutions must be aware of the importance of following ethical rules when reporting scientific work.

    2013-01-01

    Objective: To investigate the distribution of academic conflicts, if any, in medical research articles. Methods: Twenty-seven and 25 medical research articles in the field of internal medicine were selected from English and Chinese respectable jour⁃nals, respectively. Then, the speech acts that reflected a conflict between a scientist’s knowledge claim and another scientist’s knowledge claim were manually searched and recorded in each paper. Data were analyzed using non-parametric Chi-test. Results:There were 123 academic conflicts recorded in the English corpus and 49 Academic Conflicts in the Chinese corpus. Significant difference was observed in the overall frequency of academic conflicts between the English and Chinese medical discourse (p=0.001). Besides, as for the distribution within research articles, introduction and discussion sections were the sections where Aca⁃demic Conflict speech acts were most likely to occur in both corpra. Conclusion: The Chinese scholars are less likely to criticize peers. Introduction and discussion sections were the sections where Academic Conflict speech acts were most likely to occur. Our results are in agreement with previous results and confirmed the claim that highly different cultures vary in their discourse prefer⁃ences. Our findings are of pedagogical significance.

    Full Text Available Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases, vision deteriorates and can require corneal transplant surgery. Corneal collagen cross-linking (CCL with riboflavin (C3R is a recent treatment option that can enhance the rigidity of the cornea and prevent disease progression. Since its inception, the procedure has evolved with newer instrumentation, surgical techniques, and is also now performed for expanded indications other than keratoconus. With increasing experience, newer guidelines regarding optimization of patient selection, the spectrum of complications and their management, and combination procedures are being described. This article in conjunction with the others in this issue, will try and explore the uses of collagen cross-linking (CXL in its current form.

    Full Text Available Multiple sclerosis (MS is a chronic auto-immune disease. Most therapeutic strategies for treatment of this disease direct immune modulation and control of inflammatory processes. First-line therapeutic agents showed moderate efficacy and frequent side-effects with moderate efficacy in trials. Their parental administration and limited long-term adherence restrict their efficacy compared with second-line therapies. Fingolimod as a second-line therapeutic agent has been shown to reduce annualized relapse rate, risk of disability progression and inflammatory activity of relapsing MS. Safety and efficacy FTY720: Safety and efficacy issues are the main metrics for judgment of drug efficacy. In this article, we focus on cardiovascular effects of FTY720 treatment. Effect of FTY720 on rate and rhythm, impact of FTY720 on endothelial cells, its atheroprotective effects, its effects on cardiac transplantation outcomes, vascular complications of FTY720, effects of FTY720 on endocrine functions and interaction of FTY720 with cardioactive agents are explained in this review article.

    The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. Digital libraries such as the NASA Astrophysics Data System permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads, and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with the obsolescence function as measured by citations. We find that the citation function is proportional to the sum of two of the components of the readership function. This proves that the normative theory of citation is true in the mean. We further examine in...

  19. The Language of Islamophobia in Internet Articles

    Haja Mohideen

    2008-06-01

    Full Text Available Abstract: Islamophobia, the hatred for and fear of Islam and Muslims, manifests itself in physical, political, cultural, linguistic and other forms. From the linguistic perspective, many words have been coined to perpetuate prejudices against Muslims and their religion. Expressions are freely used to associate Islam, which means “peace” in Arabic, with concepts and actions which the religion and practising Muslims do not approve of, much less condone. Expressions such as Islamic terrorism, Islamic fanaticism, Muslim extremists, Islamist and political Islam have been used pejoratively. To strike fear and misgivings in the minds of many Europeans, the British capital has even been mischievously called “Londonistan” by anti-Muslim elements. Known Islamophobic items taken from Internet articles need to be analysed to respond objectively to linguistic Islamophobia.

    Full Text Available "nBackground: Rupture of pectoralis major muscle is a very rare and often athletic injury. These days in our country this injury occurs more frequently. This could be due to increase in professional participation of amateur people in different types of sport, like body building and weight-lifting (especially bench-pressing without adequate preparation, training and taking necessary precautions. In this article, we have tried to review several aspects of complex anatomy of pectoralis major muscle, epidemiology, mechanism, clinical presentations, imaging modalities, surgical indications and techniques of its rupture. Complex and especial anatomy of pectoralis major muscle, in its humeral insertion particularly, have a major role of its vulnerability to sudden and eccentric contraction as the main mechanism of rupture. Also, restoration of this complex anatomy seems to be important during surgical repair to have normal function of the muscle again.
