Pruritus in older people is caused by a wide range of dermatological, systemic, neurological and psychogenic diseases. It can also be attributed to various cutaneous drug reactions. The dermatological, neurological and immunological changes associated with ageing predispose older people to pruritus of a wide range of aetiologies. The most common cause of pruritus in older people is xerosis, or dry skin. Regular use of emollients is the mainstay of treatment for pruritus of any cause, with general measures aiming to ensure optimal skin hydration and to prevent the itch–scratch cycle. Topical treatments are generally better tolerated for localized pruritus. Anti-histamines are the predominant agents to treat pruritus, but can be inadequate in many cases. Numerous other systemic agents have been demonstrated to alleviate pruritus depending on the cause, but may be limited by their adverse effects. This article reviews the current published literature on pruritus in older people, with a practical approach to its evaluation and management in non-specialist settings.

Chronic kidney disease prevalence will continue to rise due to increased life expectancy and population ageing. It is likely that the decline in glomerular filtration rate with increasing age represents a renal manifestation of widespread vascular disease. In addition to its associated cardiovascular risk, chronic kidney disease in older people is associated with increased prevalence of geriatric syndromes such as functional and cognitive decline, which lead to disability and frailty. Competing risks for mortality, because of the co-existence of multiple co-morbidities in old age, means that the majority of older people with chronic kidney disease will not progress to end-stage renal disease. Management of chronic kidney disease in older people is complex and an individualized and holistic, rather than disease-orientated, approach is necessary, which takes into account patients’ priorities and wishes, especially frail and very elderly populations with multiple co-morbidities.

Most individuals with dementia live in the community, receiving care from family or lay carers. Carers’ wellbeing, and the quality of the care they provide, depends on their resilience in the face of the challenges associated with caring for someone with dementia. However, factors associated with carers’ resilience are not yet fully understood. The aim of this review is to present a narrative synthesis of factors, materials and resources associated with carers’ resilience. Electronic and hand searches identified relevant published literature, which was narratively synthesized. A framework consisting of three inter-related domains of factors influencing carers’ resilience emerged, encompassing: social and cultural factors; properties of the care relationship; and carers’ psychological factors. Holistic assessment based on this framework can help practitioners to identify vulnerable carers and to target help on factors that help to make them vulnerable but that are amenable to change.

Falls and fall-related injury are common and become more prevalent with increasing age. Risk factors for falling are numerous, synergistic and complex, and require multidisciplinary assessment. The evidence base for intervention strategies continues to improve, but is often limited by the methodological difficulties that are inherent in falls research. The most effective intervention is a multifactorial approach that targets identified risk factors. Multicomponent exercise, either in a group or individually, is one of the most effective components of intervention. Other successful components include home hazard modification and psychotropic medication withdrawal. Primary prevention does not appear to be cost effective, but secondary prevention far outweighs the cost of falls and fall-related injury.

As the proportion of elderly people in the general population increases, so does the number admitted to critical care. In caring for an older patient, the intensivist has to balance the complexities of an acute illness, pre-existing co-morbidities and patient preference for life-sustaining treatment with the chances of survival, quality of life after critical illness and rationing of expensive, limited resources. This remains one of the most challenging areas of critical care practice.

Syncope is a common cause of presentation to the emergency department in the older population, who are at increased risk of syncope resulting in serious injury in the form of fractures, adverse cardiac outcomes and death, lack of confidence and mental health issues. Older patients can present diagnostic challenges due to multiple co-morbidities, polypharmacy and the problem of amnesia associated with transient loss of consciousness. The underlying cause of their syncope can be established through a structured approach, and targeted patient selection can limit inappropriate investigations in syncope assessment units and ensure appropriate treatments are instituted. A previous review article in this journal, by Nath and Kenny in 2005, examined the evidence surrounding various aspects of syncope, including prevalence, cause, risks, investigations and treatment. This review updates the evidence and guidelines on the aetiology, investigation and treatments of syncope in the older person, with emphasis on recent advances.

Although sarcopenia has been used to define muscle mass loss in older subjects, muscle mass is not directly linked to muscle function. Recent definitions consider sarcopenia as a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes, such as physical disability, poor quality of life, and death. It is closely linked with physical frailty, and also with other muscle wasting disorders, including cachexia and malnutrition. This review focuses on the incorporation of sarcopenia into clinical practice, reviews case finding and diagnosis of sarcopenia, proposes a syndromic approach for the diagnostic work-up of sarcopenic patients, and looks at intervention trials with physical exercise and nutrition, as drugs to treat this condition are not expected to be available in the near future.

Transient global amnesia (TGA) has been described since the 19th century. It is characterized by an episode of anterograde and retrograde amnesia lasting less than 24 hours. During this episode patients are conscious and able to interact normally, but are typically distressed and repeat questions without remembering explanations. Despite progress in medical imaging, no cause for the condition has been proven. Prognosis is excellent and management centres on recognition and reassurance. We describe the epidemiology, pathophysiology, clinical features and management.

Emergency care of elderly patients is frequent and complex in the emergency department. Frail older patients have a high risk of poor short-term results following emergency care. There is no practical universal or standardized tool defining frailty. It must be systematically identified in older patients at risk using a screening test, and in those who are positive, a diagnostic scale of frailty or preferably a geriatric scale adapted to emergency care is carried out. An adapted geriatric assessment including brief scales related to clinical, mental, functional and social aspects has been proposed. There are currently no geriatric intervention models with sufficient evidence in frail older patients.

Coeliac disease (CD) results from immunologically mediated inflammation of the small intestinal mucosa precipitated by ingestion of gluten in wheat and other cereals in genetically susceptible people. There is a broad spectrum of clinical and histological features associated with gluten sensitivity. Overt clinical malabsorption is uncommon, and clinical symptoms are often non-specific. This is particularly true of older people and the diagnosis of CD may be delayed or missed as a result. The incidence of metabolic bone disease, neurological symptoms and nutritional deficiencies are high in older people with CD and respond well to treatment. Sensitive and specific serological tests are now available and these have improved ease of detection of CD in patients without classical symptoms. Hence, a high index of suspicion is warranted in older people with potential symptoms of CD.

Many viral infections that cause minor illness in younger adults can lead to significant mortality and morbidity in older people, particularly as co-morbidities tend to accumulate with increased age. Respiratory and gastrointestinal viruses are ubiquitous and frequently cause outbreaks, with major impact on those in care homes or residential accommodation. Advances in medicine have opened the way for increased impact of the herpes viruses (varicella zoster virus, herpes simplex virus, Epstein–Barr virus and cytomegalovirus), as immune systems are manipulated. People are also leading more active lives in older age; human immunodeficiency virus (HIV) will be increasingly prevalent, as those living with HIV grow older in good health. In addition, new diagnoses of HIV, viral hepatitis and travel-related infections will present to those working in health care of older people. This review article of viral infections aims to highlight relevant pathology, with specific reference to management in older people.

Frailty as a clinical syndrome is becoming more widely recognized and current evidence shows the importance of early detection of pre-frail states with a potential for reversibility of poor outcomes. The purpose of this review is to present the latest literature on frailty since the last review in this journal in 2007, with a particular focus on interventions aimed at reversing the processes of frailty.

Physical training, if including specific different training modalities, reduces the fall risk in healthy community-dwelling older people, as does a home hazards modification programme. Vitamin D supplementation in older individuals with low levels of vitamin D, adjustment of psychotropic medication, and structured modification of multi-pharmacy are all drug-focused programmes that reduce the number of falls. Anti-slip shoe devices during icy conditions for older people who walk outdoors and multifaceted podiatry in patients with specific foot disability reduce the fall risk. First eye cataract surgery and pacemakers in patients with cardio-inhibitory carotid sinus hypersensitivity are surgical interventions that reduce the fall risk. Multi-factorial preventive programmes that include training, both individually designed and generally prescribed, also reduce the fall frequency. With this in mind, we ought to initiate fall preventive programmes in older people, especially in high- risk groups, to reduce the number of falls and fallers in society.

Electroconvulsive therapy (ECT) is a powerful acute treatment for severe and resistant depression. We review literature related to the efficacy, safety and tolerability of ECT in older people, with an emphasis on research studies and reviews published in the last 25 years. In general ECT has been considered a very effective and safe treatment for depression and other psychiatric and non-psychiatric disorders in older people. Amnesia is commonly attributed to ECT treatment, but studies suggest that the negative effects of ECT on cognition are probably small in older patients. Currently the balance of risks and benefits of ECT justify its use for severe depression in older patients, both with and without dementia.

A major advancement in the field of medicine has been the timely advent of amyloid imaging, which has allowed critical evaluation of the complex relationship between amyloid β peptide (Aβ) aggregation and Alzheimer's disease in vivo. Most importantly, amyloid imaging has the potential to detect Aβ in mildly affected as well as asymptomatic individuals, when the therapeutic window of opportunity might still be open to pharmacological intervention. It also shows significant promise in differential diagnosis of mild cognitive impairment or atypical dementias. Amyloid imaging studies support a model in which amyloid aggregation is considered an early event on the path of dementia, beginning insidiously in cognitively healthy individuals being accompanied by subtle cognitive, functional and structural brain alterations suggestive of incipient AD. As individuals progress to dementia, clinical decline and neurodegeneration accelerate and might proceed independently of amyloid accumulation. In this review we focus on amyloid imaging with particular emphasis on [11C]PIB in AD, mild cognitive impairment and other dementias, and discuss the advances made in this perplexing field.

The lymphatic system must have variation in tissue pressure to load it and to help flow. Being a low pressure system, external pressure must not be constantly high on any segment and there must be a pressure gradient along it. When the flow rate of lymph fails there can be compromised immunity, a tendency to deposit fat, fibrotic induration, and a vicious cycle of worsening of cellular and organ health often associated with recurrent infection.

As we age we become less active, lose muscle tone, and increase our weight, develop a higher percentage of body fat, and may have poor skin care and be prescribed medications which impact on lymphatic load. Combined with this, the tendency to immobility, limb dependency and periods of time when high external pressures exist in small superficial areas increase the risk of or contribute to lymphoedema through reducing lymphatic flow. Older people are more likely to have had more radical surgery and radiotherapy for cancer with more significant damage to their lymphatic systems, again adding to lymphoedema risk. Immobility, hypertension, venous disease, kidney and liver failure can lead to oedema, while thyroid dysfunction can cause myxedema, and genetic or metabolic issues can cause lipoedema, compounding the clinical problems.

A key point in good management is early identification and accurate diagnosis. Ideally, other issues that especially impact on lymphatic load should be managed prior to targeted and sequenced treatment for the swelling, with the aim being to improve patient comfort. Management can involve the patient, partner, family or carer as well as a range of health professionals to help reduce or maintain limb size, appearance and function as well as reduce symptoms of heaviness, tension and discomfort and a range of other issues that impact on quality of life and activities of living.

Identifying what makes people vulnerable to developing Alzheimer's disease (AD) is at the forefront of many research programmes, while early diagnosis is the goal in clinical practice. What individuals themselves tell their general practitioners (GPs) is clearly important because these subjective complaints may be a clue that something is wrong. More specifically, subjective cognitive complaints (SCC) may be the first sign of AD in individuals whose cognitive performance on standard neuropsychological tasks is normal for their age. The challenge for researchers in this field is twofold: (a) determining when SCC do or do not predict current cognitive functioning and future dementia; and (b) estimating how relevant they are for patients and their proxies. The current article addresses these issues, while guidelines are also provided in an attempt to help clinicians interpret and make treatment decisions about their patients’ SCC.

Hip fracture is a common and potentially devastating injury that occurs mainly in older people. The incidence is predicted to rise by 30% in the next 10 years alone. Many of those who recover suffer a loss of mobility and independence. There is growing emphasis to improve the care of patients sustaining hip fracture, especially in those with concurrent cognitive impairment. This review focuses on current best practice as well as several key areas of management, including analgesia, anaemia and nutrition. In doing so, we hope to identify interventions that may form the basis of a future Enhanced Recovery Pathway dedicated to hip fracture care.

Shoulder disorders are very common in the older population. These can be traumatic injuries such as proximal humerus fractures, or degenerative pathology, with rotator cuff disease being the most frequently diagnosed. Lower functional demands along with the presence of co-morbidities means that conservative management is usual. However, surgery can provide pain relief and improve functional outcomes in selected patients. A thorough pre-operative assessment should be performed to avoid surgical or post-operative complications. Osteoporosis is the major concern when undertaking bone fixation in orthopaedic implants and should be routinely ruled out and treated in order to achieve better results.

The VIPS framework is a four-part definition of person-centred care for people with dementia (PCC), which arose out of an earlier review article for this journal. The definition has assisted in the practical application of person-centred care. It has been operationalized into the VIPS practice model (VPM), which has been subject to a recent randomized controlled trial within Norwegian nursing homes. The VPM provided a vehicle for the VIPS framework to be utilized during reflective practice meetings focusing on understanding care situations from the perspective of residents with moderate to severe dementia. VPM incorporated an education and coaching approach, clearly defined staff roles, and resident-focused outcomes in a cycle to support improvements in quality of care. The use of VPM in practice is discussed. VPM was built utilizing the literature from organizational change. The role of literature reviews in bringing about change in practice is highlighted.
