Pulmonary embolism is a common condition and can be the source of significant morbidity and mortality. ⋯ Various clinical decision rules and algorithms are available to assist in the diagnosis of pulmonary embolism, and the Wells score and Pulmonary Embolism Rule-out Criteria rule are presented in this article. The utility of D-dimer testing and the role of imaging to confirm the diagnosis are also discussed. Treatment options once pulmonary embolism is confirmed are presented.

Male urinary incontinence adversely affects health-related quality of life and is associated with significant psychosexual and financial burden. The two most common forms of male incontinence are stress urinary incontinence (SUI) and overactive bladder (OAB) with concomitant urge urinary incontinence (UUI). ⋯ The initial evaluation of male urinary incontinence usually occurs in general practice, and the basic work-up aims to identify reversible causes. First-line treatment is conservative management, such as lifestyle interventions, pelvic floor muscle training with or without biofeedback, and bladder retraining. Treatment options include male slings and artificial urinary sphincter surgery for men with persistent SUI, and medical therapy, intravesical botulinum toxin, sacral neuromodulation or surgery in refractory cases for those with predominant OAB/UUI.

The best use of diagnostic imaging is a challenge for many health professionals and the health system. Potential hazards of inappropriate imaging include exposure to ionising radiation, false positive and negative results, unexpected incidental findings, overdiagnosis and cost. ⋯ While normal imaging results can reassure a patient, abnormal incidental findings can sometimes cause harm. When serious disease is very unlikely, verbal reassurance may be more appropriate than imaging. We remind doctors of the risks of ionising radiation, including how to access resources to estimate these risks and the need to ensure that the potential benefit of the test outweighs the risk - the process of justification. We point readers to imaging guidelines to help guide decision-making, such as the 'Diagnostic imaging pathways' resource. We look forward to relationships between radiologists and general practitioners characterised by collaboration and consultation, rather than just ordering and reporting.

A polymorphism is a variant within a gene that does not necessarily affect its function, unlike a pathogenic mutation. Genetic testing for two common polymorphisms in the methylenetetrahydrofolate reductase gene (MTHFR), 677C>T and 1298A>C, is being accessed by general practitioners (GPs) and alternative medicine practitioners (based on in-house records from referrals), and promoted through some pharmacies in Western Australia (based on the authors' personal communication). Due to the large, varied and often conflicting data reported on MTHFR, these polymorphisms have been weakly associated with multiple conditions, including autism, schizophrenia, cardiac disease, fetal neural tube defects, poor pregnancy outcomes and colorectal cancer. ⋯ On the basis of the available scientific evidence, we propose that there are very limited clinical indications for testing for the 677C>T and the 1298A>C polymorphisms in the MTHFR gene, and that testing is not indicated as a non-specific screening test in the asymptomatic general population.
