Minor physical anomalies in children with autism spectrum disorder.

2007

Abstract Aim To investigate the rate and topological profile of minor physical anomalies (MPAs) (prenatal errors of morphogenesis) in a group of children with Autism Spectrum Disorder (ASD), in order to better set a temporal framing of embryological factors involved in the neurodevelopmental etiology. Method A new modified Waldrop scale and a mixed approach of computerized photogrammetry and classic anthroposcopy was used to detect the presence or absence of 41 MPAs in 24 children (mean age: 7 years; sex ratio: 22M:2F) with ASD and 24 healthy comparison subjects (mean age: 7 years; sex ratio: 19M:5F) selected with DSM IV and CARS. Results We found that children with ASD presenting MPAs (n =…

Comparative statistical studies on the anthropology of the Iron Age (last millennium B.C.)

1975

Abstract Extending previous statistical studies on the anthropology of the Neolithic and Bronze Ages, anthropological material from the Iron Age (1000-0) was compiled and condensed into 71 series (population samples). Penrose distances were calculated on the basis of 10 skull measurements. The dendrogram consisting of 49 larger series shows a division into a west- and an east-cluster. The west-cluster can be broken down into a northern, entirely European section, and into a southern subcluster, stretching from Sardinia to Pakistan. The east-cluster differs from the west-cluster above all in the larger width measurements, as in the case with the north-east and south-west complexes in the Neo…

Background: Cranio-facial anomalies frequently occur in neurodevelopmental disorders because both face and brain are derived from neuroectoderm. The identification of differences in the facial phenotype of children with Autism Spectrum Disorders (ASD) may reflect alterations in embryologic brain development in children with ASD. Methods: we evaluated 33 caucasian children with ASD using a 2D computerized photogrammetry. Anthropometric euclidean measurements and landmarks located on the soft tissue of the face and head, were based on five cranio-facial indexes. Relationships between anthropometric z-scores and participant characteristics (i.e., age, Global IQ, severity of autistic symptoms m…

A Preliminary Study on Cranio-Facial Characteristics Associated with Minor Neurological Dysfunctions (MNDs) in Children with Autism Spectrum Disorder…

2020

Background. Craniofacial anomalies and minor neurological dysfunction (MNDs) have been identified, in literature, as risk factors for neurodevelopmental disorders. They represent physical indicators of embryonic development suggesting a possible contributory role of complications during early, even pre-conceptional, phases of ontogeny in autism spectrum disorders (ASD). Limited research has been conducted about the co-occurrence of the two biomarkers in children with ASD. This study investigates the associative patterns of cranio-facial anomalies and MNDs in ASD children, and whether these neurodevelopmental markers correlate with intensity of ASD symptoms and overall functioning. Methods. …
