REFERENTIAL COMUNICATION SKILL IN CHILDREN WITH DOWN SYNDROME
2014
OBJECTIVES: The aim of this study is to investigate the Referential Communication skill in children with Down Syndrome (DS). In particular in this research, we have studied the development of pragmatic language in relation to non-verbal skills. It’s analyzed the Referential Communication skills in children with DS, both in production and comprehension of referential messages: oriented and / or ambiguous , adequate (appropriate) and inadequate (inappropriate) METHODS: The participants in this research are a total of 24 children: 12 children with DS and 12 children with typical development (TD) (control group). The mean age children with DS is 7 years and 8 months and the mean age children wi…
Down Syndrome and Referential Communication: Understanding and Production
2012
Abstract This study aimed to evaluate the ability of referential communication in subjects with Down Syndrome (DS). We evaluated the possibility that the referential communication is the result of a set of cognitive factors, verbal and nonverbal through the evaluation of relationship between cognitive abilities in individuals with DS and typically developing. In particular, we have identified some critical dimensions of communicative function, such as the referential communication, which means the subject's ability to produce o the listener or messages “referentially oriented”, ie messages that are characterized by “clarity or ambiguity referential”. The referential communication skills, in…
Aminoacid profile and oxidative status in children affected by Down syndrome before and after supplementary nutritional treatment
2003
Down syndrome is the most common autosomal aberration among liveborns, characterised by several clinical features and metabolic disturbances. Aminoacid pathways abnormalities and defective oxidative balance are the most common metabolic problems in Down Syndrome. To evaluate the biochemical responses of children with Down Syndrome to a nutritional regimen supplemented with aminoacids, vitamins and polyunsaturated fatty acids, we submitted 86 subjects divided in two groups (0-6 and 6-12 years) to the dosage of plasma levels of aminoacids, antioxidant enzymes activities and reactive oxygen species, before and after 12 months of such nutritional supplementation and in relation to normal contro…
Parental stress and resilience in autism spectrum disorder and Down syndrome
2020
The aim of this study was to compare parental stress and resilience in parents of children with autism spectrum disorder (ASD), Down syndrome (DS), and typical development (TD), and analyze the relationship between these two constructs. A total of 97 parents participated (ASD: n = 32, DS: n = 23, and TD: n = 42). The instruments used were the Parental Stress Index and the Resilience Scale. The ASD group obtained higher parental stress related to the child’s characteristics but not related to the parents’ characteristics. The three groups obtained moderate resilience, and high resilience was associated with low parental stress in the ASD and DS groups. The higher parental stress obtained in…
Lip and oral lesions in children with Down syndrome. A controlled study
2015
Background: Down syndrome (DS) is the most common chromosomal abnormality affecting numerous organs, including the orofacial region. The objective of the present study was to assess the prevalence of lip and oral soft tissue lesions, with particular emphasize on the incidence of fissured tongue, lip fissures and angular cheilitis, among individuals with DS in Yemen. Material and Methods: This controlled cross-sectional study included 50 children with DS (6-18 years), and 50 age- and gender-matched healthy controls. The prevalence of orofacial soft tissue lesions was evaluated in both groups. Data were analyzed by Chi-square and Fisher tests, and p <0.05 was considered to be statistically si…
Alterations in the organization of the isocortical layer I in trisomy 22.
1999
The isocortical layer I of human fetal brains obtained from different cases of chromosomal abnormalities (trisomy 18, 21, 22) and controls without pathological disturbances were investigated histologically and immunohistochemically by using the antibodies SMI 311, SMI 35 and SMI 81 (SNAP 25) as well as antibodies against GAP 43 and calretinin. In cases of trisomy 22 the Cajal-Retzius cells in Nissl-sections and in SMI 311-immunopreparations do not reveal any alterations regarding their location or morphology. However, the axonal plexus, selectively labelled with SMI 35, normally located in layer Ib, is malpositioned in Ia. Likewise, SNAP 25- and GAP 43-immunoreactive structures, which were …
Attribution style in adolescents with Down’s sindrome
2005
Educational research places emphasis on the fact that individuals who have experienced repeated failures may develop an attribution profile characterized by a bias towards primarily external causes. The aim of this study is to compare the attribution style of adolescents with Down's syndrome with that of normal children and adolescents matched for mental and chronological age; three groups consisting of 10 participants each were employed, an experimental group and two control groups were employed. The experimental group were Down's syndrome adolescents. Participants in the first control group were matched to the experimental groups for mental age, and those in the second for chronological a…
Oral health in children with physical (Cerebral Palsy) and intellectual (Down Syndrome) disabilities: Systematic review I
2016
Introduction Traditionally, patients with physical and/or intellectual disabilities presented greater oral pathology, owing to their condition and to other external factors. Improved social and health conditions make it necessary to update knowledge on their oral and dental health. Material and Methods For this purpose, a bibliographic review was done regarding the state of oral health of children with these two types of disability, in comparison with a control group. Some of the guidelines of the PRISMA statement were taken into account. The ranking of the articles found is based on the modified Newcastle-Ottawa Quality Assessment Scale. The final number of articles evaluated was 14. Param…
First trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction
2005
BACKGROUND: Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) and a large sample by ICSI. METHODS: First trimester Down's syndrome screening was performed in 1054 normal singleton pregnancies: natural conception (n = 498), ovulation induction (OS, n = 97), IVF (n = 47), ICSI (n = 222) and OD (n = 190). RESULTS: No differences in maternal levels of fbetahCG and …
Comparison of salivary cytokines levels among individuals with Down syndrome, cerebral palsy and normoactive
2019
Background Individuals with Down syndrome (DS) present increased susceptibility to infections and high prevalence of periodontal disease. The objective of this study is to evaluate the salivary concentrations of IL-1β, IL-6, IL-8, IL-10, TNFα and IL-12p70 of DS individuals and compare to cerebral palsy (CP) and normoactive patients (all with gingivitis). Material and Methods Twenty-two individuals with DS, 24 with CP and 22 normoactive participated in this cross-sectional study. Salivary flow rate, osmolality rate, Oral Hygiene Index, Gingival Index (GI) and salivary inflammatory markers IL-1β, IL-6, IL-8, IL-10, TNFα and IL-12p70 were evaluated. Shapiro-Wilks, Chi-square, ANOVA One-Way and…
