Acute pulmonary embolism (APE) is an urgent clinical condition that can progress in a wide variety of ways. Therefore, we sought to develop an easy-to-apply algorithm, to be based on readily available clinical indicators, effective in predicting unfavourable outcomes. ⋯ Advanced age (i.e. > 40 years), the presence of hypoxaemia, a recent history of trauma and the presence of pre-existing lung or heart disease are risk factors for unfavourable outcome in patients with APE.

Case Reports
Incipient non-arteritic anterior ischaemic optic neuropathy: a distinct clinical entity, the Singapore scene 3.
We report five cases of non-arteritic anterior ischaemic optic neuropathy (NA-AION) where spontaneous resolution of the optic disc swelling occurred, and all relevant visual modalities were normal at presentation and remained so until resolution of the process after a median time of 9.6 weeks. This condition, which can be termed 'incipient NA‑AION' or 'threatened NA-AION', should be recognised so that unnecessary investigations for other and more serious causes of optic disc swelling can be prevented.
