In this article, we discuss skin findings affecting older adults, with a focus on pruritus, flushing, dermatitis, and ulcers, and consider related internal diseases. Our goal is to make this information readily transferable to the clinical setting for the non-dermatologist.
Key words: dermatology, skin manifestations, older adults, pruritus, flushing, dermatitis, ulcers.

As the population ages, elder mistreatment is a growing concern in North America, and it includes physical and financial abuse and neglect. Careful documentation of the history, physical examination, and diagnostic data help achieve a clinical assessment that may be crucial to the outcome of a legal case and the protection of a patient. Good medical documentation ultimately saves clinicians time and demonstrates competency. This article discusses the items clinicians need to document in suspected cases of elder mistreatment. The emphasis is on issues that are above or beyond those performed in a routine clinical encounter.
Key words: elder mistreatment, elder neglect, elder abuse, financial exploitation, forensic documentation.

Ascites is the accumulation of free fluid in the peritoneal cavity. In over 80% of cases, it is a result of cirrhosis. Ascites develops in 60% of patients with cirrhosis within 10 years of the diagnosis of cirrhosis, and its development marks a turning point in the natural history of the disease. The mainstays of treatment are twofold: sodium restriction and diuretics. The development of spontaneous bacterial peritonitis is another ominous sign that requires indefinite antibiotic prophylaxis to prevent future infections. A referral to a transplant centre is essential once ascites or spontaneous bacterial peritonitis develop.
Key words: ascites, portal hypertension, cirrhosis, spontaneous bacterial peritonitis, paracentesis, albumin infusion.

The delivery of health care to people at home using information and communication technologies, often termed telecare, telehealth, or telehomecare, is set for rapid expansion. This article provides a brief overview of the applications and the evidence supporting its implementation. Relevant national policies in England and Canada are discussed, along with prominent examples of services and deployments. Finally, the links between research evidence, government policies, and service changes in primary care in the two countries are discussed.
Key words: telecare, telehealth, eHealth, telehomecare.

The liver undergoes substantial changes in structure and function in old age. There are age-related changes in liver mass, blood flow, and hepatocyte and sinusoidal cell morphology. These changes are associated with a significant impairment of many hepatic metabolic and detoxification activities, with implications for systemic aging and age-related disease. For example, the age-related impairment of the hepatic metabolism of lipoproteins predisposes to cardiovascular disease. The age-related decline in the hepatic clearance of most medications causes an increased risk of adverse drug reactions. Many of the beneficial effects of caloric restriction and caloric restriction mimetics such as resveratrol are mediated by their effects on the liver. Increasingly, the liver is seen as having a key role in aging.
Key words: liver, aging, hepatocyte, liver sinusoid, drug metabolism.

The following review uses case studies to illustrate the importance of a biopsychosocial approach to the assessment and management of behavioural and psychological symptoms of dementia (BPSD). Practical BPSD assessment strategies are reviewed, in addition to evidence-based and guideline-supported recommendations for acute and long-term BPSD management.
Key words: dementia, behaviour, agitation, antipsychotic, memantine.

For those with persistent gait and upper limb deficits after stroke, it is difficult to obtain recovery of motor control and functional capability in response to standard care methods. Functional electrical stimulation (FES) is a promising intervention. Surface FES for wrist and hand muscles can result in improved impairment sufficient to produce important gains in functional capability. In addition, an FES gait training system with multiple channels and implanted electrodes has shown a statistically significant additive advantage for the recovery of coordinated gait components versus a comparable comprehensive gait training treatment without FES. Results were sufficiently robust to show important gains in quality of life.
Key words: stroke, functional electrical stimulation, neuromuscular electrical stimulation, functional neuromuscular stimulation, functional recovery, rehabilitation.

The prevalence of chronic liver disease is increasing in older people. The presentation of these diseases is often asymptomatic or nonspecific, so they easily go undiagnosed. Investigating the older person who has abnormal liver function is important in primary care, and the same vigilance should be applied to an older person as to a young person, even with mild abnormalities. Referral for specialist opinion in appropriate older people provides important diagnostic and prognostic information. Treatment options are similar for all age groups. Morbidity and age-adjusted mortality are often more severe in older people; therefore, early diagnosis and intervention are important.
Key words: chronic liver disease, aging, liver function tests.

The prevalence of gallstones has been increasing among the aging population. Common sequelae of cholelithiasis include asymptomatic gallstones, biliary colic, acute cholecystitis, choledocholithiasis, cholangitis, and gallstone pancreatitis. Among individuals over age 65, gallstone diseases represent an important cause of recurrent abdominal symptoms and surgical admissions. As advanced age is correlated with increased mortality and morbidity in complicated gallstone disease, timely diagnosis and appropriate management are essential to improving disease outcomes.
Key words: older adults, gallstones, cholecystitis, choledocholithiasis.

Increases in life expectancy and the aging of the baby boomer generation has resulted in unprecedented high numbers of older adults in the U.S. and Canada and, thus, a rising number of frail older adults with chronic medical conditions. Informal caregivers, primarily family members, have traditionally provided a large proportion of care at home, and their contribution is expected to be of even greater significance. Informal caregivers provide care at great expense to themselves, because caregiving can result in emotional, physical, and financial stresses. This article discusses the role physicians play in identifying and alleviating caregiver stress.
Key words: family caregivers, informal caregivers, caregiver stress, physician, older adults.
