Neurodevelopmental markers that are present early in childhood may identify children at risk for later developmental disabilities. This paper attempts to clarify the relationship between one such proposed marker, toe walking, and language development in a general pediatric population. One hundred sixty-three children being seen for well-child visits were included in the study. Information from each child's caretaker was obtained for language development and a history of toe walking; observation of toe walking during the visit was also included. The frequency of toe walking was 24%. Language quotients were calculated and compared for toe walkers (n=39) and non-toe walkers (n=127). The mean language quotient for toe walkers tended to be consistently lower than that for non-toe walkers. The specificity of toe walking for low language scores was 85% but had a sensitivity of only 32%. Although an association between toe walking and language delay is supported by the present data, the association does not appear to be clinically significant.

Retrospective history of middle ear disease was compared with developmental diagnosis in 507 consecutively referred school-age children. History of major ear problems was positively associated with discrepancies between the performance and verbal IQ on the WISC-R. History of major ear problems was positively associated with the presence of articulation disorders for children in the low social class, hyperactivity in the middle social class, and language problems in the high social class. A history of significant middle ear disease in early childhood should raise concerns for articulation difficulties and possible language problems in children presenting to clinicians with school problems.

Retrospective maternal report of fetal activity level was compared with developmental diagnosis in 608 consecutively referred children. Maternal history of fetal activity level was also obtained from 140 unmatched well children in a general pediatric clinic. Fetal hyperactivity was positively associated with a diagnosis of child hyperactivity, and fetal hypoactivity was positively associated with a diagnosis of mental retardation in the children. Maternal histories of fetal activity level in the control group weakened the strength of the association between fetal hyperactivity and child hyperactivity but did not affect the association between fetal hypoactivity and mental retardation in children.

"When Arnold Capute goes through the spastic motions of a child with cerebral palsy (CP), an initial impression is that he is dramatizing his comments with rather callous mimicry. But no, he is not imitating a CP child. For the moment, as his head snaps backward and his arms flex uncontrollably, he is a CP child, just as later in discussing the primitive reflexes of infants (of which the fencing position is most common), he momentarily becomes a newborn infant. Dr. Capute is a man of unabashed empathy and enthusiasm and he is wholly convinced that medical therapy can do much more than previously to overcome developmental disabilities in children. So keen and articulate is Dr. Capute in elaborating on his subject matter that the Hopkins pediatric house staff chose him to receive the Alexander Schaffer Award this past June for excellence in clinical teaching.

After a detailed behavioral and developmental history has been supplemented by the use of formal questionnaires, the diagnosis of an attentional disorder can be further clarified by the judicious selection of psychoeducational and pediatric physical and neurodevelopmental examinations. The most common difficulty in the interpretation of psychoeducational test subscores and profiles is the significant overlap between the patterns generated by attentional deficits and those associated with memory-based learning disabilities. Certain other medical and behavioral conditions need to receive careful consideration prior to finalizing the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD). A thorough but focused general examination coupled with the pediatric neurodevelopmental examination can contribute to this differentiation.

Thirteen elementary school age children with acute leukemia who had received cranial irradiation with dosages between 1,800 and 4,800 rads a mean of 6.3 years earlier were evaluated for the presence of learning disorders. The authors utilized both psychometric and educational tests. The results were analyzed according to a graduated regressed standard score procedure and yielded the following diagnoses: mental retardation, two (15%); learning disability in reading and mathematics, two (15%); learning disability in mathematics, five (39%); no psychoeducational diagnosis, four (31 %). Of the nine children (69%) who qualified for a specific psychoeducational diagnosis, only three were receiving any special educational services. The failure of a previous assessment of this same group of children at our center and of other research reports to uncover a similarly high incidence of neurodevelopmental pathology may be due to the specific tests employed or to the later onset of measurable difficulties in these patients.

Although language is recognized as one of the best predictors of develop ment, the lack of a simple evaluation tool has contributed to the general pediatrician's unfamiliarity with linguistic milestones. Here described is a 32-item instrument for the recording and assessment by the practicing pediatri cian of language milestones during the first two years of life.

Toe walking unassociated with an autistic disorder or cerebral palsy generally has been considered a normal infant gait. The incidence of toe walking in various diagnostic subgroups of 799 developmentally disabled children presenting to a tertiary-level multidisciplinary assessment clinic was reviewed to investigate the authors' clinical impression that toe walking may be a marker for language dysfunction. Toe walking was found to be more frequent in those diagnostic subgroups with more severe language disorders. Toe walking also correlated with lower IQ scores (p < 0.0001). The sensitivities, specificities, predictive validities and odds ratios all supported the hypothesized association between toe walking and language disorders. Further prospective studies of the neurodevelopmental outcome of children with toe walking are needed to determine whether this behavior can identify children at risk for language disorders.

Six cases of inner city black children with both infantile autism and lead poisoning are reviewed. In three cases, developmental deviance seems to have been present before the possible impact of lead toxicity. In two cases the lead poisoning may have contributed to the onset or acceleration of developmental symptomatology. In one case the temporal sequence remains unclear. Possible patterns of interaction and the implications for clinical practice are discussed.
