Care of cerebral-palsied children; the special role of pediatricians

Because the cerebral-palsied child is also a growing person whose development should be encouraged along as normal a course as possible, the pediatrician may well take the lead in coordinating orthopedic, psychiatric, educational and vocational services for such children. In El Centro this policy has been followed in a school for handicapped children serving 30 with cerebral palsy, 15 of them pupils at the school. Those with sufficient intelligence and milder physical handicap attend a regular public school, while others are unable to attend even the special school. Emphasis has been placed on working with children who are less seriously affected. As to children with severe neuromuscular and intellectual handicap, the chief effort is to prevent contractures and maintain function. The pediatrician confers monthly with all workers concerned with the child, and maintains liaison with the family physician who treats acute illnesses, including palsy seizures. Special effort has been made to investigate family circumstances such as foreign background which make it more difficult to evaluate the palsied child's true capabilities.

The growth of IQ among Estonian schoolchildren from ages 7 to 19

The Standard Progressive Matrices test was standardized in Estonia on a representative sample of 4874 schoolchildren aged from 7 to 19 years. When the IQ of Estonian children was expressed in relation to British and Icelandic norms, both demonstrated a similar sigmoid relationship. The youngest Estonian group scored higher than the British and Icelandic norms: after first grade, the score fell below 100 and remained lower until age 12, and after that age it increased above the mean level of these two comparison countries. The difference between the junior school children and the secondary school children may be due to schooling, sampling error or different trajectories of intellectual maturation in different populations. Systematic differences in the growth pattern suggest that the development of intellectual capacities proceeds at different rates and the maturation process can take longer in some populations than in others.     

Seduced by Images: Identity and Schooling in the Lives of Puerto Rican Girls

Based on a two-year ethnographic study at an urban middle school, this article describes the power that images created by and about Puerto Rican girls hold in shaping their schooling experiences. Using a black, critical, feminist framework, I show how dichotomizing the sexuality of Puerto Rican females against their intellectual development obscures the complex ways that identities are co-constructed and then affirmed, appropriated, or resisted within their school site. I conclude that to resist the reproduction of educational inequality in the lives of Puerto Rican females, we must explore and seek to transform the influential ways that identities are mediated and educational outcomes are produced within the school contexts where Puerto Rican females are educated .

Paradigmatic Processes in Culture Change

Paradigmatic processes in culture change are defined, in the sense of Thomas Kuhn, as the consequence of long-continued deliberate effort by numbers of persons to innovate within a recognized technical, artistic, or intellectual tradition (or "school" or "discipline"). The evolving paradigm will often, after a certain point of development, attract exploitation; there will then occur various functionally entailed social-cultural consequences; and ultimately efforts will be made to rationalize the change in religious, ethical, and philosophical terms.

The Fundamental Processes of Mental Life

Arithmetic is one of the complex forms of human intellectual activity. This kind of intellectual operation is usually studied by psychologists. It has been found that the learning of arithmetic by children is closely related to the development of speech, the perception of spatial relations, and the maturation of higher forms of analytic-synthetic activity by the cerebral cortex. The development of the intellectual operations of arithmetic goes through several stages from visual-operational forms to abstract forms [9-11].     

Intellectual development of 15- to 16-year-old boys and girls: Psychophysiological structure

The structure of intelligence in senior adolescents has been studied. The analysis of intelligence in adolescents of both sexes has shown that there are no distinct differences in the structure of intellectual development between boys and girls aged 15–16 years. Significantly better results have been obtained only for the memory development of girls. This suggests that the pattern of cognitive development does not depend on the sex at the last stages of puberty. Significant variation of individual intellectual characteristics confirms a high variability of the psychophysiological structure of intelligence in adolescents at this ontogenetic stage.     

Relation between biochemical severity and intelligence in early treated congenital hypothyroidism: a threshold effect.

OBJECTIVES--To assess whether early treatment of congenital hypothyroidism fully prevents intellectual impairment. DESIGN--A national register of children with congenital hypothyroidism who were compared with unaffected children from the same school classes and matched for age, sex, social class, and first language. SETTING--First three years (1982-4) of a neonatal screening programme in England, Wales, and Northern Ireland. SUBJECTS--361 children with congenital hypothyroidism given early treatment and 315 control children. MAIN OUTCOME MEASURES--Intelligence quotient (IQ) measured at school entry at 5 years of age with the Wechsler preschool and primary scale of intelligence. RESULTS--There was a discontinuous relation between IQ and plasma thyroxine concentration at diagnosis, with a threshold at 42.8 nmol/l (95% confidence interval 35.2 to 47.1 nmol/l). Hypothyroid children with thyroxine values below 42.8 nmol/l had a mean IQ 10.3 points (6.9 to 13.7 points) lower than those with higher values and than controls. None of the measures of quality of treatment (age at start of treatment (range 1-173 days), average thyroxine dose (12-76 micrograms in the first year), average thyroxine concentration during treatment (79-234 nmol/l in the first year), and thyroxine concentration less than 103 nmol/l at least once during the first year) influenced IQ at age 5. CONCLUSIONS--Despite early treatment in congenital hypothyroidism the disease severity has a threshold effect on brain development, probably determined prenatally. The 55% of infants with more severe disease continue to show clinically significant intellectual impairment; infants with milder disease show no such impairment. The findings predict that 10% of early treated infants with severe hypothyroidism, compared with around 40% of those who presented with symptoms in the period before screening began, are likely to require special education.     

Differences in Perception and in the Operational Level of Thinking of Children Four to Eight Years Old

Today the importance for intellectual development of a child's acquisition of the conservation of quantity is generally recognized. However, the question of the mechanism of the ontogeny of invariant perception has not yet been definitively resolved. Piaget and his disciples thought that the genesis of invariant perception depended basically on internal structural equilibria, as a result of which new structures (inventions) constituting the basis of intellectual development are formed. In recent years, adherents to this theory have begun to admit a limited possibility of intervening in the development of intelligence [7,8,12].     

Psychophysiological Correlates of Writing and Reading Difficulties in Children of Elementary School Age

A psychophysiological study of the mechanisms underlying writing and reading difficulties at elementary school included assessment of the actual level of speech development, language abilities, intellectual functions, visual memory, visuomotor coordination, and neuropsychological parameters of first- and third- or fourth-grade students. The leading mechanisms of writing and reading difficulties were identified for different stages of skill formation. The role of factors determining the efficiency of learning changed accordingly. From the first to the third (fourth) grade, a decrease was observed in the role of the factors of speech development, formation of motor skills, visual perception, and visual memory, while the voluntary organization of activity, working capacity, and fatigability became the most significant factors. At all stages of teaching writing and reading, the rate of teaching activity must correspond to the functional and adaptive capabilities of schoolchildren.

Grades of undernutrition and socioeconomic status influence cognitive development in school children of Kolkata

Cognitive development of children is influenced by different environmental factors like nutritional and socio‐economic status. The objectives of the present study were to determine the influence of grades of undernutrition and socio‐economic status (SES) on the cognitive development of school children of Kolkata. Five hundred sixty six (566) school children having 5–12 years of age were selected from different schools of Kolkata. The cognitive development was measured by the scores of Raven's colored progressive matrices (RCPM). The chronic and acute nutritional statuses were measured from height‐for‐age (HAZ) and weight‐for‐age (WAZ) Z scores respectively with reference to the values of WHO. SES was determined by updated Kuppuswamy scale. The prevalences of undernutrition in the observed children were 57.95% (according to HAZ) and 52.82% (according to WAZ). The age dependent growth curve of RCPM scores of the observed children remains in between the 10th and 25th centile of British children. The children belonging to superior and intellectual deficit IQ classes were 21.55 and 36.40%, respectively of the total subjects. Most of the subjects belong to lower middle (39.93%) and upper middle (36.40%) class of SES. RCPM scores of school children were gradually decreased with the grades of undernutrition and SES. RCPM scores were significantly correlated with HAZ, WAZ, SES, age, and sex (P < 0.001) and strongly associated with HAZ, SES, age, and sex (P < 0.001, P < 0.05). Present study indicates that cognitive development of school children of Kolkata is influenced by the grade of undernutrition and SES.

The Concept of Developmental Teaching

Both theoreticians and educational practitioners have been devoting increasing attention in the past few years to the problems of developmental teaching. Some major scientific works have been devoted to these problems, which are being tackled in various special textbooks and methodological manuals. The Ministry of Education of the Russian Federation is preparing and publishing special programs on developmental teaching [42]. All these efforts are evidence that the problems of the intellectual, moral, and physical development of schoolchildren are becoming very urgent in our education—moreover, one of the principles of reform of contemporary school education is that authentic developmental teaching be put to ample use (see, for example [20. Pp. 159-160], etc.).     

A consideration of the patentability of enantiomers in the pharmaceutical industry in the United States

During the last thirty years, concern over stereoselectivity of drug action has drawn a great deal of interest within the pharmaceutical field due to an improved understanding of the pharmacology and pharmacokinetics of enantiomers. Developing single enantiomers versus racemates or introducing a single enantiomer following the development of the racemic mixture appears to be the new trend. The intellectual property status of single enantiomers from racemates may be unclear. Drug discoverers and patent attorneys must examine the examples of the past to establish an appropriate pathway towards the development and intellectual property protection of chiral drugs. The review will focus on the patenting of an enantiomer in view of the prior art disclosure for the racemic mixture.

Autism and Intellectual Disability-Associated KIRREL3 Interacts with Neuronal Proteins MAP1B and MYO16 with Potential Roles in Neurodevelopment

Cell-adhesion molecules of the immunoglobulin superfamily play critical roles in brain development, as well as in maintaining synaptic plasticity, the dysfunction of which is known to cause cognitive impairment. Recently dysfunction of KIRREL3, a synaptic molecule of the immunoglobulin superfamily, has been implicated in several neurodevelopmental conditions including intellectual disability, autism spectrum disorder, and in the neurocognitive delay associated with Jacobsen syndrome. However, the molecular mechanisms of its physiological actions remain largely unknown. Using a yeast two-hybrid screen, we found that the KIRREL3 extracellular domain interacts with brain expressed proteins MAP1B and MYO16 and its intracellular domain can potentially interact with ATP1B1, UFC1, and SHMT2. The interactions were confirmed by co-immunoprecipitation and colocalization analyses of proteins expressed in human embryonic kidney cells, mouse neuronal cells, and rat primary neuronal cells. Furthermore, we show KIRREL3 colocalization with the marker for the Golgi apparatus and synaptic vesicles. Previously, we have shown that KIRREL3 interacts with the X-linked intellectual disability associated synaptic scaffolding protein CASK through its cytoplasmic domain. In addition, we found a genomic deletion encompassing MAP1B in one patient with intellectual disability, microcephaly and seizures and deletions encompassing MYO16 in two unrelated patients with intellectual disability, autism and microcephaly. MAP1B has been previously implicated in synaptogenesis and is involved in the development of the actin-based membrane skeleton. MYO16 is expressed in hippocampal neurons and also indirectly affects actin cytoskeleton through its interaction with WAVE1 complex. We speculate KIRREL3 interacting proteins are potential candidates for intellectual disability and autism spectrum disorder. Moreover, our findings provide further insight into understanding the molecular mechanisms underlying the physiological action of KIRREL3 and its role in neurodevelopment.     

Study of intellectual performance of children in ordinary schools after certain serious complications of whooping cough. Swansea Research Unit of the Royal College of General Practitioners.

In a case-control study 27 index children from ordinary schools who had had convulsions or apnoea as a complication of whooping cough about eight years previously were compared with 27 children who had never had whooping cough and 15 who had had whooping cough without complications. Other factors likely to cause intellectual impairment after conception were considered. The index group had a significantly lower median intelligence quotient and poorer school attainment than either of the control groups. The results support the hypothesis that convulsions or apnoea as a complication of whooping cough may be associated with subsequent intellectual impairment.     

Physical activity and the healthy mind.

Physicians should seek to enhance the quality rather than the quantity of human life. Physical activity programs can increase life satisfaction through an immediate increase of arousal and a long-term enhancement of self-esteem and body image. In the young child competition can cause excessive arousal, but long-term adverse effects are rare. In the adult a reduction of anxiety and stress and a general feeling of well-being reduce the frequency of minor medical complaints, generating important economic benefits. Physical activity programs also help to correct the reactive depression that accompanies conditions such as myocardial infarction. Interest in physical activity should be stimulated from the earliest years of primary school. The allocation of curricular time to physical education does not hamper academic achievement. Rather, through its impact on psychomotor learning, it enhances the total process of intellectual and psychomotor development.
