Head injuries in infants and children: Measures to reduce mortality and morbidity in road accidents

In the 6-year period from 1983 to 1988, 12 infants (<24 months of age) and 103 children (2 to 14 years of age) were killed in road crashes in South Australia. This represents an annual incidence of 6.4 deaths per 100,000 children at risk. At least 4 other children were killed in off-road vehicle-related accidents. Of these deaths, approximately half were car passengers, one third pedestrians, and one sixth pedal cyclists. Most of these infants and children died at the accident site or soon after, but 26 of them survived long enough to be admitted to hospitals with neurosurgical units and an audit of these patients suggests that there were at least 3 preventable deaths. However, autopsies of 78 patients show that the great majority of these deaths resulted from devastating brain and/or trunk visceral injuries. Better emergency care and the use of neurosurgical retrieval teams may save some lives. But more lives might be saved by the use of appropriate restraints for infants and children in cars, by reducing the exposure of child pedestrians and cyclists to road traffic, and by mandatory use of helmets by child cyclists. Off-road vehicular accidents are not as a rule included in road crash statistics; the practice of giving small motorcycles to young children has created a new category of vehicular accidents sometimes causing severe head injury.

Resumen En el período de seis anños 1983–1988, murieron 12 infantes (edades menores de 24 meses) y 103 niños (edades 2–14 años) en accidentes viales en el Sur de Australia, lo cual representa una incidencia anual de 6.4 muertes por 100,000 miños en riesgo. Por lo menos cuatro niños más murieron en accidentes fuera de carreteras pero relacionados con automotores. De tales muertes, approximadamente la mitad correspondió a pasajeros en carros, una tercera parte a peatones y una sexta parte a ciclistas. La mayoría murió en el lugar del accidente o poco tiempo después, pero 26 sobrevivieron un tiempo sufiente para ser hospitalizados en instituciones con unidades neurológicas; una auditoría de tales casos sugiere que por lo menos hubo tres muertes prevenibles. Sin embargo, la autopsia de 78 casos demostró que la mayoría de estas muertes se debió a lesiones devastadores del cerebro y/o las vísceras corporales. Mejores servicios de urgencia y la utilización de equipos de resucitación neuroquirúrgica pueden salvar algunas vidas, pero más vidas pueden ser salvadas mediante el uso de sistemas adecuados de seguridad para infantes y para niños instalados en los carros, reduciendo la exposición de peatones y ciclistas infantiles al tráfico víal y mediante el uso obligatorio de cascos por los ciclistas infantiles. Los accidentes que ocurren por fuera de las carreteras generalmente no son incluídos en las estadísticas de siniestros víales; la costumbre de obsequiar pequeñas motocicletas a niños pequeños ha creado una nueva categoría de accidentes vehículares que en ocasiones causan grave trauma craneano.

Résumé Pendant la période de six ans allant de 1983 à 1988, 12 enfants âgés de moins de 24 mois et 103 enfants âgés de 2 à 14 ans ont été tués dans un accident de la route en Australie du Sud. Ceci représente une incidence annuelle de 6.4 morts par 100,000 enfants à risque. Au moins quatre autres enfants ont été dans un accident dû à un véhicule motorisé mais hors de la route. Parmi ces morts, la moitié, environ, était des passagers de la voiture, un tiers, des piétons, et un sixième, des cyclistes. La plupart sont morts sur le lieu de l'accident, mais 26 ont survécu suffisamment pour être transportés dans un Hôpital comportant une service de neurochirurgie avant de décéder. Une évaluation de ces accidents mortels a montré qu'au moins trois décès eux étaient évitables. L'autopsie de 78 de ces enfants a démontré que la plupart des décès étaient dus soit à des lésions cérébrales, soit à des lésions viscérales ou du tronc. De meilleurs soins en urgence, et un meilleur déploiment des équipes neurochirurgicales pourraient éviter quelques morts, mais aussi, un certain nombre de morts pourraient être évitées en utilisant correctement less ceintures de sécurité adaptées aux enfants dans les voitures, en réduisant l'exposition aux accidents de ces enfants, ainsi qu'en rendant obligatoire le port de casque pour les enfants se déplacant à vélo. Les accidents qui n'ont pas lieu sur les routes ne sont pas habituelement inclus dans ces statistiques. La croissance de l'utilisation de petits véhicules motorisés par de très jeunes enfants a créé une nouvelle catégorie d'accidents pouvant parfois être responsables de traumatismes crâniens graves.

     

Executive cognitive deficits in primary dystonia.

Primary dystonia is a disorder of movement for which no consistent pathophysiology has been identified; in the absence of evidence to the contrary, it is assumed to be cognitively benign. We have studied a clinically heterogeneous group of 14 patients with primary dystonia on a battery of neuropsychological tests. Despite well-preserved speed of information processing, language, spatial, memory and general intellectual skills relative to normal controls, we have identified a constellation of attentional-executive cognitive deficits on the Cambridge Neuropsychological Test Automated Battery (CANTAB). Specifically, patients demonstrated significant difficulties negotiating the extra-dimensional set-shifting phase of the IED task. The implications of these findings for the pathophysiology of primary dystonia are discussed. This is, to the best of our knowledge, the first report of a significant cognitive deficit in patients with primary dystonia.     

Facial reanimation with the VII-XII anastomosis: analysis of the functional and psychologic results

The VII-XII anastomosis has been employed for more than a decade by The Otology Group, P.C., in the facial reanimation of patients undergoing extirpation of tumors involving the cerebellopontine angle and the skull base. A retrospective review based upon a detailed questionnaire and submitted photographic documentation from 61 patients forms the basis for this review. Details and analysis of the functional results include onset of function, synkinetic activity, corneal irritation and associated ophthalmologic problems, facial tone and symmetry, and volitional mimetic function. From a psychosocial perspective, evaluation was made regarding workplace and home acceptance, self consciousness, adaptation, and overall satisfaction. Because of the nature of its technical performance and reliability, the VII-XII anastomosis is an important technique for the otolaryngologist to be familiar with. Cognizance of the functional and psychologic results with this procedure will ensure optimal (yet realistic) rehabilitation for this patient population.     

Improvement in depressive illness is not associated with altered release of neurophysins over a course of ECT

The hypothesis that the release of vasopressin-associated neurophysin (hNpI) or oxytocin-associated neurophysin (hNpII) is modified by a course of electroconvulsive therapy (ECT) was tested by the measurement of serum neurophysins before and after the first and last ECTs given to 17 unipolar depressed patients. Neither basal nor ECT-induced neurophysin release changed between the first and last ECTs. Data from the present study were combined with data from a previous published study to provide a sample of 29 unipolar depressed patients. In this extended sample, the release of hNpII after the first ECT was significantly correlated with improvement in symptoms of depression over a course of ECT as measured by the Hamilton Rating Scale for Depression and the Montgomery-Asberg Depression Rating Scale.     

Desmoplastic malignant melanoma: An aggressive tumor

Summary The clinical features and histological appearance of desmoplastic malignant melanoma are presented. Aggressive surgical management and close follow-up are mandatory if this highly aggressive tumor is to be controlled. Despite this, the prognosis is poor.
