The number of older substance misusers requiring treatment is likely to double over the next couple of decades. However, there are many misconceptions and myths about this often hidden population. Older people misuse alcohol, nicotine, prescription medication and illicit drugs. ⋯ Patients present to a very wide variety of social and medical care settings, so screening and assessment for substance use are of paramount importance. This provides the opportunity to determine to what extent the substance problem is related to the presentation, which may be subtle and atypical in older people. Since evidence is accumulating of the benefit of treatment for substance problems in the older population, this group should not be marginalised and neglected by practitioners, researchers, educators and policy makers.

Eosinophilic oesophagitis is a clinico-pathologic diagnosis that describes patients with dysphagia (intermittent or continuous), food bolus obstruction or regurgitation, where endoscopy and biopsy reveals high concentrations of eosinophils in the lining of the oesophagus. At endoscopy, the presence of rings (trachealisation), furrows, micro-abscesses and strictures may be noted, but sometimes the appearance is normal. ⋯ It is important for all general physicians to recognise this and make an accurate diagnosis in order to give specific treatment. This may involve topical steroids, leukotreine D4 antagonists, dietary exclusions and dilatations.

The field of HIV medicine has changed rapidly in the last two decades since effective and tolerable antiretroviral treatment became available. As a result, although classical opportunistic infections of the brain have become less common, clinicians need to be aware of a wider range of acute and chronic complications of HIV and its treatment. In this article, we summarise major opportunistic infections, immune reconstitution inflammatory syndrome, HIV-associated neurocognitive disorders, and cerebrovascular disease in HIV positive patients. We also emphasise the preventability and reversibility of most of the central nervous system complications of HIV, and hence the importance of early diagnosis of HIV and involvement of clinicians with special expertise in HIV medicine.

The diverse and complex community of microorganisms that has co-evolved with the human gut is vital to intestinal functioning, and disturbances in the microbiota and its relationship with the host immune system have been linked to inflammatory bowel diseases, including Crohn's disease and ulcerative colitis. This has suggested several treatment options, including antibiotics, probiotics and faecal transplantation. The human microbiome project has been established to enable comprehensive characterisation of the human microbiota and in the coming years, knowledge in this area is expected to continue to expand.

Stroke is an important cause of death and disability throughout the world. Most strokes are ischaemic, caused by thrombotic or embolic occlusion of blood vessels. The advent of thrombolysis for acute ischaemic stroke has revolutionised the treatment of acute stroke in the developed world. ⋯ Clinical stroke services need to ensure that all acute stroke patients can be scanned, treated and admitted to stroke units without delay. Future research needs to address the prevention and better management of complications, such as secondary intracerebral haemorrhage and angioedema. In addition, the evidence base for direct intra-arterial intervention such as thrombectomy needs to be established.
