Timing of prenatal stressors and autism

Recent evidence supports a role for genetics in autism, but other findings are difficult to reconcile with a purely genetic cause. Pathological changes in the cerebellum in autism are thought to correspond to an event before 30-32 weeks gestation. Our purpose was to determine whether there is an increased incidence of stressors in autism before this time period. Surveys regarding incidence and timing of prenatal stressors were distributed to specialized schools and clinics for autism and Down syndrome, and to mothers of children without neurodevelopmental diagnoses in walk-in clinics. Incidence of stressors during each 4-week block of pregnancy was recorded. Incidence of stressors in the blocks prior to and including the predicted time period (21-32 weeks gestation) in each group of surveys was compared to the other prenatal blocks. A higher incidence of prenatal stressors was found in autism at 21-32 weeks gestation, with a peak at 25-28 weeks. This does support the possibility of prenatal stressors as a potential contributor to autism, with the timing of stressors consistent with the embryological age suggested by neuroanatomical findings seen in the cerebellum in autism. Future prospective studies would be needed to confirm this finding.

American Academy of Pediatrics. Committee on Children with Disabilities. The treatment of neurologically impaired children using patterning

This statement reviews patterning as a treatment for children with neurologic impairments. This treatment is based on an outmoded and oversimplified theory of brain development. Current information does not support the claims of proponents that this treatment is efficacious, and its use continues to be unwarranted.

American Academy of Pediatrics. Committee on Children With Disabilities. Care coordination: integrating health and related systems of care for children with special health care needs

Care coordination is a process that links children with special health care needs and their families to services and resources in a coordinated effort to maximize the potential of the children and provide them with optimal health care. Care coordination often is complicated because there is no single entry point to multiple systems of care, and complex criteria determine the availability of funding and services among public and private payers. Economic and sociocultural barriers to coordination of care exist and affect families and health care professionals. In their important role of providing a medical home for all children, primary care pediatricians have a vital role in the process of care coordination, in concert with the family.

Responding to the developmental consequences of genetic conditions: the importance of pediatric primary care

This article characterizes the critical role of the primary care physician in the identification, initial evaluation, and management of children with developmental disabilities. Problems of definition and epidemiology are reviewed and linked to issues of referral and eligibility for services and supports. Developmental screening methods afford opportunities for early identification, whereas chronic condition management in primary care defines a more explicit role for the pediatric primary care provider.

Autosomal dominant familial spastic paraplegia: description of a large New England family and a study of management

A large New England family with autosomal dominant familial spastic paraplegia (ADFSP) is described. In a pedigree of 173 family members, 71 affected individuals were identified. 16 cases examined by the authors are described with regard to the natural history of ADFSP in this family, and a staging system for following progress and planning interventions is proposed. Three illustrative cases are presented. In this family, ADFSP was found to have a homogeneous clinical course, with nearly complete penetrance. Onset, with involvement limited to the lower extremities, occurred by three years of age, after which no significant progression was noted. Early, aggressive habilitative care may result in more functional ambulation for the youngest family members.

Reactions of mothers and medical professionals to a film about Down syndrome

Parents, genetic counselors, and nurses were shown an 18-minute video-taped discussion involving parents of persons with Down syndrome and were asked to complete an evaluation. Some of the statistically significant differences were as follows: 89% of mothers believed that the film was an accurate portrayal of parental attitudes compared with 14% of the genetic counselors and 40% of the nurses; 48% of genetic counselors believed that problems outweigh the benefits in parenting a child with Down syndrome, but 94% of mothers and 83% of nurses thought that the benefits predominated; and 56% of genetic counselors believed that parents of a child with Down syndrome would choose to abort a subsequent affected fetus while only 8% of parents and 10% of nurses agreed. It is important that medical professionals have a balanced and accurate view of the impact of Down syndrome on families.

Autosomal dominant familial spastic paraplegia: report of a large New England family

A large New England family with autosomal dominant familial spastic paraplegia is described. In a pedigree of 173 individuals, 71 affected individuals are identified. Seventeen cases examined by the authors are described with regard to the natural history of FSP in this family. A staging system for following progress and planning interventions is proposed. Three illustrative cases are presented. In this family, FSP is found to have a homogeneous clinical course with nearly complete penetrance. Onset occurs at or before 3 years of age with involvement limited to the lower extremities. After the initial onset, no significant progression was noted. Early aggressive habilitative care may result in more functional ambulation.

Free proximal trisomy 21 without the Down syndrome

Analysis of partial duplication of chromosome 21 suggests that band 21q22 contains determinants for the Down syndrome. We report two cases of free proximal trisomy 21 without manifestations of the Down syndrome. Phenotypic anomalies included marked microcephaly, short stature, hypoplastic nails, and mental retardation/developmental delay. Our cases are consistent with the assignment of band 21q22 as the causal duplicated segment in the Down syndrome.
