To evaluate the relative importance of the medical history, the physical examination, and laboratory investigations in the diagnosis and management of medical outpatients some physicians recorded their diagnosis and a prediction of the method of management after reading the patient's referral letter, again after taking the history, and again after performing the physical examination. These diagnoses and predictions were compared with the diagnosis and method of management which had been adopted two months after the patient's initial attendance. A diagnosis that agreed with the one finally accepted was made after reading the referral letter and taking the history in 66 out of 80 new patients; the physical examination was useful in ot..y seven patients, and the laboratory investigations in a further seven. In only one of six patients in whom the physician was unable to make any diagnosis after taking the history and examining the patient did laboratory investigations lead to a positive diagnosis.

The content of interventions for caregivers of dementia patients is highly varied. None of the reviews conducted to date have focused on evaluating the effects of the content of interventions exclusively for dementia caregivers, and this issue is not well understood. The purpose of this review was to first identify the type of components (e.g. education, counselling) that have been utilized in psychosocial/psycho-educational interventions for dementia caregivers, and to evaluate the success of the different components or combination of components in producing positive outcomes for dementia caregivers. Forty studies were included in the review. Approximately two-thirds of the interventions did not show improvements in any outcome measures. Among those studies, which did demonstrate improvements, the inclusion of social components (e.g. social support) or a combination of social and cognitive (e.g. problem solving) components seemed to be relatively effective. It is important to note, however, that these analyses were based on small numbers and the review was limited by a number of methodological issues (e.g. poor description of interventions). To advance our understanding of the efficacy of psychosocial interventions for caregivers of people with dementia, a more systematic approach is required. Intervention components need to be carefully contrasted in appropriately designed studies of sufficient size.

The purpose of this study is to describe the process of parenting a child with life-threatening heart disease. Despite advances in pediatric cardiac sciences, hypoplastic left heart syndrome remains difficult and controversial to treat. The Norwood surgical approach is a developing technology, and little is known about how mothers and fathers experience parenting a child who survives this treatment. Constructivist grounded theory informed this Canadian study that involved multiple interactive interviews with 9 mothers and 7 fathers of children with hypoplastic left heart syndrome who were at various stages of treatment. Extraordinary parenting in a context of uncertainty was evident as parents simultaneously safeguarded their child's precarious survival as well as their own survival. As technologically advanced treatment contributes to the survival of children with complex health conditions, health care professionals must consider how to promote and support parenting strategies that benefit the new survivors of technology as well as their families.
