A re-analysis of the Sydney Diet Heart Study (Ramsden et al., BMJ 2013) suggested that a diet high in linoleic acid increased the risk of coronary heart disease. The authors ascribe this to a lack of the omega-3 fatty acid, alpha-linolenic acid, in the oils and fats consumed. This argument has some weaknesses. ⋯ Additionally, the fats consumed by subjects in the intervention group were high in trans fats, which may have increased risk. Finally, a large recent clinical trial failed to show any benefit of linolenic acid. The conclusion is, therefore, that this re-analysis provides insufficient evidence to justify changes in current dietary recommendations.

A 43-year-old woman came to the Emergency Room with acute abdominal pain during the night. CT examination of the abdomen showed ventral herniation of the stomach and parts of the small intestine and colon in the right hemithorax. We made the diagnosis 'symptomatic Morgagni hernia', a rare congenital defect that is usually diagnosed soon after birth.

Screening for lung cancer with computed tomography (CT) appears to be highly effective. A large randomized trial in the United States reported a 7% reduction in all-cause mortality in patients screened by CT in comparison with those screened by chest radiography. ⋯ As CT is superior to radiography in lung cancer detection, CT seems the preferred imaging modality for case finding. As more trial results have to be awaited and cost-effectiveness and optimal screening strategy remain uncertain, CT lung cancer screening is not yet ready for implementation.

Advance directives containing a request for euthanasia in cases of severely debilitating dementia are of no use. In such an advanced stage of the disease, the doctor would have to administer lethal medication to a patient who does not realise what is happening to him/her. The Dutch Euthanasia Act is ambivalent about this possibility.

A substantial number of patients suffering from aortic dissection will show neurological signs. These can dominate the clinical picture and hinder an accurate diagnosis of this life-threatening disease. We present a case of lower extremity pain and a case of transient global amnesia caused by aortic dissection. ⋯ High-risk clinical features are predisposing factors in medical history, typical acute onset back or chest pain, and pulse deficit, blood pressure asymmetry or a new cardiac murmur on physical examination. These features should be explicitly evaluated in patients with an acute neurological deficit. If neurological symptoms and a high-risk clinical feature are present, immediate aortic imaging should be considered since early detection can be life saving.
