OBJECTIVE This study investigated the relationship between mental retardation and lifetime events in patients with Duchenne muscular dystrophy (DMD). METHODS The data on mental retardation and ages of lifetime events (first walking, loss of ambulation, introductions of ventilator support and tube nutrition and death) were collected retrospectively, and the relationships between the factors we...

Sum mary Aim: Several factors including genetic factors, nutrition and environment play a critical role in the growth of children. Adenotonsillar hypertrophy (ATH) can cause growth retardation by obstructing the upper airway. Surgical treatment of ATH has been considered to have a positive effect on growth. The aim of this study was to evaluate the role of chronic ATH on growth by measuring wei...

The study reported here classified 9,660 newborn infants delivered at a maternal and child health center in Mexico City by length of gestation, presence or absence of growth retardation, and (in the case of growth-retarded infants) proportionate or disproportionate growth retardation in terms of the infants' weight and length. It was found that preterm infants (delivered before 38 weeks of gest...

Sjogren-Larsson Syndrome (SLS) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. We report a case of Sjogren-Larsson Syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and MRI findings such as seen in multiple sclerosis (MS). So this rare syndrome can be another differen...

A diagnosis of mental retardation carries with it certain unique treatment needs that must be understood and addressed. Unfortunately, most psychiatrists are ill-equipped to handle this situation, having received little or no formal training in this area. This article is written with the specific goal of giving psychiatrists a better understanding of the special needs of patients with mental re...

SOURCES OF DATA MEDLINE (January 2000 through October 2003), using the following key words: mental retardation, developmental disability, child, and adolescent. Search of the Pediatrics and New England Jou...

The aim of this paper is to clarify which kinds of retardation foils are most suited to extend the viewing angle of π-cells [1]. For this reason we focussed on the simulated conoscopic retardation plots of the π-cell on the one hand and of the retardation foils on the other hand. Among the foils we investigated are hybrid retardation layers with positive and negative birefringence, homogeneous ...
