The transition experience of epilepsy patients/families: results of a telephone survey.

Little has been written about the transition experiences of persons with epilepsy and their families. The results of the survey presented in this report support the notion that transition from pediatric to adult care for persons with chronic illness can be very painful. The sadness produced by the ending of close relationships, and fear and uncertainty about the future are commonly experienced emotions at this time. Careful assessment and planning by the entire team coupled with cooperative efforts between adult and pediatric care providers are necessary to ensure a smooth and seamless transition from pediatric to adult epilepsy care.

Injury prevention programs: do they really make a difference?

Brain and spinal cord injuries are a leading cause of death and disability for the youth of Canada (Damba et al, 1996). The costs of these injuries to the individual, the family, and society at large are immense. Most of these injuries are preventable (Tator et al, 1993). Over the last decade, a number of injury prevention programs have been developed to address the high incidence of traumatic central nervous system (CNS) injuries in young people. However, what remains unclear is how effective these programs are in terms of altering risk-taking behaviours. The following paper/presentation will highlight three injury prevention programs currently offered in the Toronto area: The Party Program. The Heroes Program, and The Think First Program. Each program will be outlined in terms of historical development and infrastructure, content, setting, format, and intended audience. In addition, each program will be evaluated based on criteria established by the author. Measurement of outcomes will also be addressed.

Advanced concepts in the management of cerebral vasospasm associated with aneurysmal subarachnoid hemorrhage.

Despite advances in the diagnosis and surgical treatment of aneurysmal subarachnoid hemorrhage (SAH), the morbidity and mortality rates remain disturbingly high. In those patients that survive the initial event, deaths due to re-bleeding have been reduced as a result of a trend to earlier surgical repair of the aneurysm. Unfortunately, a large percentage of patients go on to die or become permanently disabled from cerebral infarction as a consequence of vasospasm. The exact mechanisms that contribute to the development of cerebral vasospasm in these patients continue to elude researchers. The pathological processes implicated in the vasospasm phenomenon will be described. Even though no single pharmacological agent or treatment protocol has been identified that prevents or reverses this deadly complication, a number of promising intervention strategies are being employed in the critical care setting. These will be explored in light of the most current research findings. Clearly, early detection and prompt treatment are vital if the outcomes for persons suffering aneurysmal SAH are to improve. A sound knowledge base, well-developed assessment and clinical reasoning skills, and a deeper understanding of the pathological processes and treatment objectives will assist the neuroscience practitioner to more ably care for these most challenging patients.

The cardiopulmonary complications of aneurysmal subarachnoid hemorrhage: current trends in management.

It is well established that excessive sympathetic activity, resulting in the development of cardiopulmonary complications, commonly occurs in patients who have suffered aneurysmal subarachnoid haemorrhage. Cardiac dysfunction and neurogenic pulmonary edema are life threatening conditions that have serious implications with regard to patient outcome. The purpose of this article is to familiarize the neuroscience practitioner with the effects of subarachnoid haemorrhage on the heart and lungs and to provide an update in terms of current medical and nursing management trends. It is vital that these patients receive aggressive therapy including definitive surgical treatment of the aneurysm, vigilant monitoring for cardiopulmonary complications and prompt medical and nursing intervention should they occur. A brief review of the anatomy and physiology of the sympathetic division of the autonomic nervous system will be presented. In addition, the theories that have been proposed to explain the underlying pathogenesis will be introduced. Medical and nursing management strategies will also be addressed.

The pain experience of a multiple sclerosis population: a descriptive study.

A detailed survey questionnaire was distributed to patients attending a multiple sclerosis clinic for the purpose of describing the pain experience of an MS population. Three hundred and sixty-four (364) questionnaires were completed and returned for evaluation. Two hundred and thirty-three (233) or 64 percent of subjects surveyed reported painful symptoms at some time during the course of their disease. Data was gathered and analyzed with regard to age, gender, duration of illness, age of onset of MS, employment status, classification of disease, onset of painful symptoms and their frequency and intensity. Similarities between the two groups (pain vs no pain) were observed in mean age (44.15 years vs 43.40), duration of illness (10.97 years vs 10.26 years), employment status (56 percent employed vs 57 percent employed), age of disease onset (33.74 years vs 32.07 years) and breakdown of illness classifications in both groups. Onset of pain was reported at time of diagnosis or before in 41 percent of subjects surveyed. Females were more likely to complain of pain than were men (68 percent vs 55 percent) and tended to report a significantly higher pain intensity than males. Forty-nine percent of subjects with pain reported difficulty working, 44 percent difficulty sleeping and 34 percent reported troubled interpersonal relationships. Forty percent of patients with pain report never being completely pain free.
