Plasma amino-terminal pro-brain natriuretic peptide levels in subjects presenting to the Emergency Department with suspected acute coronary syndrome: possible role in selecting patients for follow up?
Plasma amino-terminal pro-brain natriuretic peptide (NT-proBNP) level is a sensitive and specific indicator of cardiac dysfunction. ⋯ Although elevated NT-proBNP level detected heart failure with high sensitivity, NT-proBNP level did not assist in the diagnosis of acute myocardial ischaemia. These findings indicate that the major determinant of elevated NT-proBNP level on presentation with suspected ACS was underlying cardiac dysfunction rather than acute myocardial ischaemia. This suggests that NT-proBNP measurement in patients with a suspected cardiac reason for presentation to the Emergency Department may identify a previously unrecognized group of patients without acute ischaemia who may nevertheless benefit from further investigation of cardiac function.

Adverse drug events as a cause of hospital admission in the elderly.
Previous studies of adverse drug events (ADE) as a cause of hospital admission in the elderly have often been limited in their ability to assess fully the impact and potential for prevention because they either did not include all categories of ADE and/or did not assess severity and preventability. ⋯ Adverse drug events are a common preventable cause of unplanned medical admissions in the elderly. Non-compliance and omission of indicated treatment are causes of ADE-related admissions that are both preventable and frequently associated with severe ADE.

Scleroderma in South Australia: epidemiological observations of possible pathogenic significance.
Scleroderma is an autoimmune disorder of unknown cause. Previous epidemiological studies have suggested some regional clustering and associations with occupations involving exposure to silica dusts and hydrocarbons. ⋯ No strong genetic or environmental influences were found to account for the relatively common occurrence of scleroderma in SA. The age at onset versus age-specific incidence curve suggests that scleroderma can be considered as a stochastic illness involving a number of random events occurring in a predisposed population. These random events may involve mutations of pivotal somatic genes.
