Attentional function as measured by a Continuous Performance Task in children with dyscalculia.

This study determined whether or not students with dyscalculia had difficulty with attention as measured by the Conners' Computerized Continuous Performance Test (CPT). Fifty-six control subjects and 27 subjects with dyscalculia were administered the CPT. Performance was measured using percent omission errors, percent commission errors, mean response time, SE of response times (SE-RT), and a calculated overall attention index (CPT Index). Compared with controls, subjects with dyscalculia had higher CPT Index scores, made more omission errors, and had more inconsistent response times (SE-RT). Multiple regression analysis of arithmetic scores showed that SE-RT and percent commission errors were the only CPT measures that contributed to the arithmetic scores. Problems with attention, as measured by the Conners' CPT, were associated with lower arithmetic achievement scores. Students who have difficulties in arithmetic may have more attentional problems than other children, and students with attentional difficulties may be at risk for difficulties in arithmetic.

The relationship of the glenoid fossa to the functional occlusal plane.

The geometric relationship of the functional occlusal plane to the center of the glenoid fossa, as seen in the sagittal view, is described for males and females from age 7 through 25 years. This relationship is fully described by the distance from the geometric center of the glenoid fossa perpendicular to the functional occlusal plane (L, in millimeters) and its angulation (theta, in degrees) relative to a constructed Frankfort horizontal (SN-7 degrees ). Regression formulas with 95% confidence levels are described for L and theta for both genders combined. The differences between genders were found to be statistically insignificant. No correlation was found between these dimensions relative to the presence of temporomandibular joint dysfunction symptoms. A statistically significant difference in both L and theta was found in males who exhibited a Class III relationship compared with males exhibiting a Class II relationship.

Early ear problems and developmental problems at school age.

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.

Maternally reported fetal activity levels and developmental diagnoses.

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.

[Reconstruction of foot arteries after injury in arterial occlusive disease].

At the Maribor Teaching Hospital two elderly with progressive atherosclerotic disease below the knee were treated between 1986-1992 for open fracture of ankle joint and pedal arterial trauma. The only patent atherosclerotic vessel (dorsal artery of the foot) that was disrupted was reconstructed in both cases by interposition of a part of the great and small saphenous vein in one case each. A termino-terminal anastomosis with a long, triangular patch was used, fixed with interrupted sutures. The fractures were stabilized with external fixators. Both extremities were saved.

Toe walking and language development.

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.

Minor malformations, hyperactivity, and learning disabilities.

Standardized minor malformation scores have been reported to predict and identify children with attentional problems and hyperactivity. The reason why this marker works for only a subset of children with attention deficit hyperactivity disorder remains unclear. The dysmorphology scores on all children presenting for a multidisciplinary team evaluation of developmental disorders were examined for diagnostic correlations after children with chromosomal disorders and recognized dysmorphic syndromes were excluded. For 1233 subjects, the mean minor malformation score was 2.94 (SD = 2.05). A significant association between minor malformation scores and IQ (mean = 80.95, SD = 23.67) was accounted for by the group with IQs greater than 100 exhibiting the higher dysmorphology scores. An analysis of variance revealed no significant association between minor malformation scores and hyperactivity or attention deficit disorder. Indeed, the presence of an attention deficit disorder yielded lower mean dysmorphology scores. When the minor malformation scores were compared for those subgroups of children with and without specific learning disabilities, the learning-disabled subjects had significantly higher dysmorphology scores. Minor dysmorphic features do not relate to the presence or absence of attentional problems or hyperactivity in referred children. Rather they appear to characterize that subpopulation of children with attention deficit disorder and learning disabilities as well as a group of learning-disabled children without attentional disorders.

Administrative role and educational administration program effectiveness: perception by principals.

A survey of 85 graduates from 14 midwestern universities offering doctoral degrees in educational administration was carried out to assess perceptions of graduates regarding their training program. The emphasis of the survey was on how closely their training corresponded to current perceptions of their roles as educational administrators. Most indicated emphasis in graduate training should more closely match the roles of administrators.
