RESUMO
OBJECTIVES: The purpose was to demonstrate that an objective, multivariate case definition of fetal alcohol syndrome (FAS) and partial fetal alcohol syndrome (PFAS) can be derived by means of craniofacial anthropometry. STUDY DESIGN: Craniofacial measurements (n = 21) were taken of 100 individuals who had been exposed to alcohol before birth (41 FAS, 59 PFAS) and 31 members of a control group. Multivariate discriminant analysis was used to identify craniofacial measurements that best differentiated the 3 groups (FAS, PFAS, and control). RESULTS: Both the FAS and PFAS groups had a unique craniofacial phenotype that could be accurately discriminated from that of the control group. Stepwise discriminant analysis identified 6 craniofacial measurements that could differentiate individuals with and without prenatal alcohol exposure with 96% accuracy, 98% sensitivity, and 90% specificity. CONCLUSIONS: Individuals with FAS and PFAS have a distinctive facial phenotype that can be characterized anthropometrically. The phenotypic case definition could be used as a screening tool to identify individuals prenatally exposed to alcohol who do not exhibit a "classic" FAS phenotype but exhibit a more subtle craniofacial dysmorphia.

The natural history of Williams syndrome, including medical complications, growth patterns, and problems in adulthood, was investigated. A growth pattern characterized by delay in the first 4 years of life, catch-up growth in childhood, and low ultimate adult height was found. Despite multiple medical problems in infancy, including feeding problems, failure to thrive, colic, and otitis media, mean age at diagnosis was 6.4 years. Developmental disabilities and cardiovascular disease were the major concerns in childhood. The older children developed progressive joint limitation and hypertonia. Adult patients were handicapped by their developmental disabilities. Hypertension, and gastrointestinal and genitourinary problems occurred frequently. Independent living and competitive employment were limited less by the individual's physical problems than by the psychologic and adaptive limitations. Williams syndrome is a progressive disorder with multisystem involvement.

The proportion of women with tetanus antitoxin titers adequate to provide protection for themselves and for their newborn infants varied from 96% in New Haven, Connecticut to 19% in Santiago, Chile. Women of childbearing age in five of the nine areas (São Paulo, Recife, and Pôrto Alegre, Brazil; Ecuador; and Gazankulu, South Africa) had an average of 40% immunity to tetanus and did not differ significantly from one another. By comparison with Chile, where vaccination during pregnancy is not current policy, we estimate that 21%-34% of the women in these five areas had received toxoid recently. In general about half the women with inadequate titer had undetectable levels of antibody and may require more than one dose of vaccine to attain immunity.
