Hyperlipidaemia is a major risk factor for the development of atherosclerosis and cardiovascular disease. Statins are the mainstay of therapy and new guidelines focus on the use of these agents without specific targets for low-density lipoprotein (LDL)-cholesterol or non high-density lipoprotein (HDL)-cholesterol. ⋯ Specialised therapies are in development for treatment of orphan disoders such as homozygous familial hypercholesterolaemia (lomitapide) or familial chylomicroaemia (alipogene tiparvovec). These novel lipid-lowering agents are likely to find uses in treating patients at the highest cardiovascular risk.

Insulin therapy is important in many patients with diabetes, but the UK National Diabetes Inpatient Audit (NaDIA) suggests that insulin therapy in hospital is poorly monitored and managed. Although most hospitals should have access to an inpatient diabetes specialist team, it is important for the non-specialist clinician to be aware of the indications for insulin therapy, types of insulin and insulin regimens, methods of adjusting insulin doses and the need for care with insulin prescribing. Here, we demystify issues around insulin therapy.

The optimum management of acute medical patients requires prompt and accurate diagnosis, monitoring and treatment. The clinical history and physical examination remain central to diagnosis, but often need supplementation by laboratory testing or imaging. Echocardiographic assessment of cardiac structure and function provides valuable information that can aid diagnosis and assess clinical progress. ⋯ Hand-held ultrasound devices can also be used in acute situations, as well as geographically remote areas or special situations (eg disaster zones) where other imaging is not available. However, the diagnostic yield of echocardiography is user dependent, and training is required for its benefits to be realised, adding to the hardware costs. More data are needed on the incremental value of hand-held ultrasonography and a quick-scan over conventional methods of assessment, their impact on clinical outcomes, and cost effectiveness.

The purpose of modern radiotherapy is to deliver a precise high dose of radiation which will result in reproductive death of the cells. Radiation should transverse within the tumour volume whilst minimising damage to surrounding normal tissue. Overall 40% of cancers which are cured will have received radiotherapy. ⋯ Brachytherapy enables very high radiation doses to be delivered by the direct passage of a radiation source through or within the tumour volume and similar results can be achieved using rotational stereotactic X-ray beam techniques. Protons have the characteristics of particle beams which deposit their energy in a finite fixed peak at depth in tissue with no dose beyond this point - the Bragg peak. This has advantages in certain sites such as the spine adjacent to the spinal cord and particularly in children when the overall volume of tissue receiving radiation can be minimised.

An increasing number of women who are pregnant have diabetes, whether gestational or pre-existing. Diabetes in pregnancy is associated with a number of adverse outcomes including birth trauma, neonatal hypoglycaemia, macrosomia and pre-eclampsia. Those with pre-existing diabetes have the additional risks which include congenital defects and increased perinatal mortality. This paper summarises the complications of diabetes in pregnancy and highlights some of the recent controversy surrounding the diagnosis of gestational diabetes.
