Acute myeloid leukaemia (AML) is a heterogeneous disease characterised by clonal malignant haematopoiesis with a differentiation arrest and excessive proliferation of leukaemic blasts. Over the past decades, the heterogeneity of AML has been illustrated by evolving classifications based on morphology (French-American-British classification (FAB classification), cytogenetic abnormalities (e.g. t(8;21), monosomies etc.), phenotype and÷or molecular abnormalities (e.g. Fms-like tyrosine kinase 3 gene internal tandem duplication (FLT3-ITD), mutations in nucleophosmin 1 (NPM1) and the transcription factor CCAAT ÷enhancer binding protein a (CEBPA), etc.). ⋯ However, enhanced understanding of the molecular biology of AML will likely result in more 'tailor-made' therapies, for example by adding specific tyrosine kinase inhibitors to standard chemotherapy. In this review, we summarise the variables currently used to classify AML. Specifically, the contribution of microarrays in classification, prognosis and understanding of pathobiology of AML is discussed.

Large colorectal cancer screening studies using primary colonoscopy have reported a low risk of major complications. Studies on diagnostic and therapeutic colonoscopy have pointed to a frequent occurrence of(minor) cardiopulmonary events, and with the steady increase of colonoscopy screening, it is important to investigate their occurrence in colonoscopy screening. ⋯ Mainly procedure-related and not subject-related factors were found to be associated with the occurrence of cardiopulmonary events in primary colonoscopy screening in this relatively healthy screening population.

Case Reports
Recovery from near drowning and postanoxic status epilepticus with controlled hypothermia.
A diver was resuscitated after cardiac arrest due to near drowning and was hypothermic on hospital arrival. During rewarming, status epilepticus occurred, previously identified as a predictor of poor outcome. ⋯ This case supports the hypothesis that hypothermia offers neuroprotection, even in the presence of status epilepticus. We recommend that near-drowning victims who are comatose after resuscitation for cardiac arrest be treated with controlled mild hypothermia for 12 to 24 hours.
