Mental development after modified pi procedure: dynamic cranioplasty for sagittal synostosis.

A prospective developmental assessment was performed on 26 patients operated on with dynamic cranioplasty for sagittal synostosis. Because this technique entails the application of compressive force, it was of great concern to assess the effect of surgery on development and mental status. The surgical technique used was a modified pi procedure. Perioperative variables were recorded. Six patients underwent preoperative intracranial pressure (ICP) measurements. To evaluate objectively the developmental outcome, the Griffiths' Mental Development Scales was used for analysis before and after surgery. A parental questionnaire was used for subjective outcome measurement. Preoperative ICP recordings during sleep ranged from 12.8 to 22.8 mmHg (mean, 16.1 mmHg). The mean age at the time for surgery was 6.9 months (range, 4-16 months; standard deviation [SD], 2.32 months). The surgical technique included shortening of the anteroposterior diameter of the skull by a mean of 16.6 mm. The mean global development quotient (GDQ) preoperatively was 104.5 (range, 82-144; SD, 12.4) and the mean GDQ postoperatively was 101.4 (range, 62-129; SD, 13.6). Mean age at follow-up was 16.3 months (range, 9-40 months; SD, 4.04 months). There was no significant correlation between the amount of intraoperative shortening and mental development. In comparison of means, the GDQ preoperatively did not differ significantly from the GDQ postoperatively. The modified pi procedure is safe and efficient. When surgery was performed before 1 year of age, no significant (p = 0.33) effect on mental development-either detrimental or beneficial-was demonstrated.

Pupils with mild mental retardation in regular Swedish schools: prevalence, objective characteristics, and subjective evaluations.

Pupils in regular Swedish schools who met the psychometric criterion of mental retardation were identified and described. Using a national longitudinal data set, we compared a group of 13-year-old pupils (N = 116) not officially classified as having mental retardation to their peers without mental retardation across measures of school achievement, social background, self-evaluations of school experiences, and upper secondary school education. The results showed that the former group was low-achieving and had poor self-evaluations; however, some pupils in the general population shared these characteristics.

Longitudinal studies of mental development.

Two longitudinal research projects--Individual Statistics and Evaluation through Follow-up of Students (UGU)--are presented. Their overriding aim is evaluation of the role of school in individual developmental processes. Mental development is one interest of study. The sequential design and data collected are briefly presented. Four representative samples of students born 1948, 1953, 1967 and 1972 are under study. Two smaller exemplifying studies are presented. The first is a cross-sectional comparison between thirteen-year-olds tested in 1961, 1966 and 1980 with identical tests. The average level of results on spatial and reasoning tests have risen since 1961. There were no changes in differences between students from white-collar and blue-collar background. Differences between boys and girls had changed, though. There was no verbal test difference in 1961 but in 1980 girls performed better than boys. Concerning spatial and reasoning ability, boys were clearly better 1961 but that difference had practically disappeared 1980. In the other study MMR students are defined within the 1967-born cohort. Some data on their school-experiences are presented. They face more difficulties and have more remedial teaching than other low ability students, but most of them complete compulsory schooling and 2/3 have plans for secondary education. Plans for future analyses are presented.
