Abstract

The preextraction profile record is a means of easily, quickly, and inexpensively recording clinical data prior to extraction of the natural teeth. The record contains a great deal of preextraction information and can be easily stored in the patient's chart. However, the preextraction profile record does not obviate the need for other preextraction records such as radiographs, photographs, and diagnostic casts. The information recorded in preextraction records allows the dentist to have access to and compensate for the progressive changes which occur when the natural teeth are extracted.

[Rett syndrome a developmental disorder. Presentation of a variant with preserved speech].

Rett's syndrome is a disorder of neuropsychological development of unknown aetiology. All those described as having all the classical traits of the syndrome are girls. Typically apparently normal development in the first year of life is followed by loss of acquired hand skills and speech, together with deceleration in the growth of the head and development of characteristic hand washing movements, hyperventilation and mental retardation. The disorder is the most common cause of progressive mental retardation in girls. Parents experience health workers who have not heard about this disorder. The article describes a four year-old girl with some preserved speech and an ability to sing. This is an atypical trait in a variant of Rett's syndrome. The importance of cooperation between different professions and medical specialties is underlined. Early diagnosis and start of intervention may delay loss of function. Controlled clinical trials, both medical and psychological, are needed.

The size of the intra- and extraventricular cerebrospinal fluid compartments in children with idiopathic benign widening of the frontal subarachnoid space.

The aim of this study was to quantify the intra- and extraventricular cerebrospinal fluid (CSF) spaces in children with benign enlargement of the frontal subarachnoid space (BE). The infra- and supratentorial CSF compartments were measured in 61 CT examinations of children with BE, 3-27 months old, and compared with those of 96 CT examinations considered normal. Measurements of the ventricular system, and the pontine and chiasmatic cisterns were related to cranial size. In all children with BE the lateral and third ventricles were dilated and the chiasmatic cistern was widened. The subarachnoid space was wider than the upper limits in the control group, in the frontal region (4 mm), and the anterior interhemispheric (4 mm) and Sylvian (3 mm) fissures. The infratentorial CSF compartments, the occipital subarachnoid space, the posterior part of the interhemispheric fissure and, in most cases, the cortical sulci were normal in size in children with BE. The majority were macrocephalic or had rapid head growth but there were also normocephalic children with normal head growth. The size of the posterior fossa was within the normal range in all children with BE. Idiopathic BE is not uncommon in children up to about 3 years old who are healthy or have minimal neurological disturbance and is characterised by a specific pattern of widening of the supratentorial CSF compartments.

Assessment of mass properties of human head using various three-dimensional imaging modalities.

Better methods are needed to analyse personal protective devices, such as helmets or facemasks, before they are used in practice. Software tools to quantify three-dimensional craniofacial mass properties are developed to improve our understanding of craniofacial impact biomechanics, supplement existing knowledge of osseous structure and provide a comprehensive description of human head morphology. The application of state-of-the-art imaging systems, solid modelling and other software tools are studied to determine the associated errors in mass property estimation by spiral computed tomography, three-dimensional magnetic resonance and optical surface scanning using phantoms and cadaver head studies. Volume, centre of gravity and principal moments of inertia are determined from solid mathematical models for each scanning modality. Landmark-based registration is used to register scans of the same object obtained from the three imaging modalities to a common reference co-ordinate system. Physically and analytically determined mass properties are used as the standard for truth. Although this comparative study does not lend itself to statistical analysis owing to the small sample size, results indicate that any of the three imaging modalities can be used to predict mass properties within the uncertainty of existing methods. Applying these techniques in vivo is practical and feasible.
