Craniofacial malformations and their syndromes. An overview for the speech and hearing practitioner.

Congenital malformations of the craniofacial region represent an important class of human developmental disorders. Abnormalities of speech and hearing frequently occur in this vast array of conditions. Knowledge of the diagnostic criteria, genetics, and natural history of these conditions is important for audiologists and speech-language pathologists because of their close involvement with the children and families in their care-providing role. Awareness of the important distinction between individuals with isolated defects vs. individuals who have their facial defect as part of a syndrome is important in diagnosis and management. Referral for genetic counseling is always indicated in families who have questions about these issues. The dysmorphologist, genetics professional, and speech-language pathologists are among those who play key roles in the care of persons with these disorders.

Use of carbon fibers for repair of abdominal-wall defects in rats.

Carbon in the form of 8-micron fibers induces growth of connective tissue. The purpose of this study was to measure and histologically characterize tissue ingrowth occurring in carbon fibers implanted for up to 12 months in abdominal-wall defects in rats, compared with polypropylene mesh. Carbon fibers induced significantly more tissue ingrowth than polypropylene mesh at 6 to 12 months postoperatively. The predominant tissues associated with carbon fibers and polypropylene mesh were dense connective tissue and fat, respectively. Fragmentation of the implants did not occur, and implant debris was not found in the regional lymph nodes. Carbon fibers are potentially useful for reinforcing abdominal-wall defects.

Effects of repeated assessment on standardized test performance by infants.

Infant-intervention programs that evaluate their effectiveness by repeatedly testing infants with standardized tests may confound intervention effects with repeated-testing effects. Further, maternal participation in testing may increase infants' test scores, either directly by giving infants practice with test-like items at home between test administrations or indirectly by helping infants adapt to the test setting. Thirty-five infants were tested at 3-month intervals between 4 and 28 months of age with the Bayley Scales of Infant Development and at 31 months of age with the Stanford-Binet; 25 infants were tested with the Bayley at 4 months and the Stanford-Binet at 31 months. Mothers of some infants in each group participated in the testing process. Between-subjects analysis on the Stanford-Binet revealed no effects for repeated testing or maternal participation. Within-subjects analyses for repeatedly tested groups demonstrated that maternal presence during testing, but not repeated testing, was associated with significantly higher Bayley scores. It was concluded that maternal presence is a potent influence on Bayley performance, that repeated experience with the Bayley biased neither performance on another standardized test of development nor subsequent Bayley performance, and that infant intervention programs are not likely to confound their evaluation designs by testing infants repeatedly.
