Constructing biological knowledge bases by extracting information from text sources.

Recently, there has been much effort in making databases for molecular biology more accessible and interoperable. However, information in text form, such as MEDLINE records, remains a greatly underutilized source of biological information. We have begun a research effort aimed at automatically mapping information from text sources into structured representations, such as knowledge bases. Our approach to this task is to use machine-learning methods to induce routines for extracting facts from text. We describe two learning methods that we have applied to this task--a statistical text classification method, and a relational learning method--and our initial experiments in learning such information-extraction routines. We also present an approach to decreasing the cost of learning information-extraction routines by learning from "weakly" labeled training data.

Mortality following spinal cord injury.

This study analyzed the mortality in 1453 spinal cord injured patients admitted early after injury to a specialised Spinal Injuries Unit within a University teaching hospital over a 40-year period. The cohort comprised 55.3% patients with cervical lesions and 44.7% patients with thoracic/lumbar lesions. Those patients who died within 18 months of the spinal injury (132) were excluded from the final analysis. Standardised Mortality Ratios, survival rates and life expectancy ratios were calculated for specific ranges of current attained age and duration since injury with reference to level and degree of spinal cord injury. The projected mean life expectancy of spinal cord injured people compared to that of the whole population was then estimated to approach 70% of normal for individuals with complete tetraplegia and 84% of normal for complete paraplegia (Frankel grade A). Patients with an incomplete lesion and motor functional capabilities (Frankel grade D) are projected to have a life expectancy of at least 92% of the normal population.

Mental health services in the family physician's office: a Canadian experiment.

This paper describes a program in Hamilton-Wentworth, Ontario, Canada, that brings mental health counselors and psychiatrists into the offices of 87 local family physicians, working in 35 practices serving 170,000 people. It outlines the organization of the mental health teams in the family physician's office and the way in which these teams are coordinated and discusses how this "shared care" approach can overcome many of the problems that traditionally bedevil the relationship between psychiatric services and family practices. It summarizes the benefits of this approach for patients providers and the health care system and looks at its implications for learners and for new approaches to continuing education. This model can be adapted to most communities.

Integrating mental health services within primary care. A Canadian program.

The increasingly prominent role of the family physician in delivering mental health care can be enhanced if productive and collaborative relationships can be established with local mental health services. This paper describes a Canadian program that has achieved this by bringing mental health counselors and psychiatrists into the offices of 87 family physicians in 35 practices in a community in Southern Ontario. The paper describes the program, the activities of counselors and psychiatrists within the practices, and the administrative structures set up to coordinate these activities. Data is presented from the evaluation of the first year of the program's operation (13 practices and 45 family physicians) during which time 3085 referrals were received. The program made mental health care more available and accessible, increased continuity of care, provided additional support for the family physician, offered new opportunities for continuing education, and led to a reduced and more efficient use of other mental health services. The components of the program can be adapted to most communities.

An integrated regional emergency psychiatry service.

This paper presents a model of an integrated Psychiatric Emergency Service serving Hamilton, a community of 450,000 in Southern Ontario. It describes the evolution of the service and how it has integrated five separate, hospital-run Emergency Psychiatric Services into a single service. The principles of the service and ways in which it operates are outlined and the advantages and drawbacks of the model are discussed. The authors conclude that such a model leads to a more efficient use of resources and is adaptable to most urban communities with a similar, or even larger population.

Case reviews in the family physician's office.

The majority of patients with emotional or psychiatric disorders are treated in the primary care setting without psychiatric input. Psychiatrists need to find ways of helping family physicians manage these patients without necessarily taking over their care. One way of achieving this is for a psychiatric consultant to visit the family physician's office on a regular basis to discuss the physician's problem cases. This paper describes such a pilot project, outlines the kinds of problems family physicians discussed and recommendations that were made, and discusses the benefits of this collaborative approach.

The surgical treatment of childhood moyamoya disease.

Moyamoya disease is a progressive disorder, predominantly seen in childhood, that can cause severe permanent disability. The search for effective treatment has largely been unsuccessful in the past, but recent efforts at surgical intervention have shown promising results. The natural history of moyamoya disease, the options for treatment, and a series of patients from the Hospital for Sick Children in Toronto are reviewed. The results of surgical treatment are encouraging and the authors believe that it should be offered to all pediatric patients in the progressive stage of the disease.
