Abstract
The use of artificial nutrition and hydration (ANH) has become relatively commonplace. With the development of the PEG years ago, the difficulties that surrounded the use of naso-gastric feeding tubes have all but disappeared. However, the clinical, ethical and legal aspects of ANH have replaced issues of procedural techniques and the discomfort experienced by older patients when the nasogastric tubes were used for prolonged periods. Many in the field of aging and long-term care in particular are particularly sensitive to the long-term implications for the patient and family once ANH is implemented. The issues of starting such intervention when its discontinuation may cause moral conflict, legal challenges and for many who are believers religious conundrums must be considered especially when such decisions are being made during a period of crises and clinical uncertainty.
Key Words: artificial nutrition, hydration, long-term care, implications.

Abstract
The pathogenesis of acne is tied to Propionibacterium acnes (P. acnes), an anaerobic bacteria. There has been a dramatic rise in resistance to antibiotics that are usually prescribed to treat acne. Given resistance to antibiotic therapy can occur in more pathogenic bacteria than P. acnes, and the fact that a rise in pathogenic P. acnes has been reported, the development of antibiotic resistance in acne is a public health matter globally. Clinical practice guidelines are aiming to curb the further development of antibiotic resistance without detracting from effective management of both inflammatory and non-inflammatory acne.
Key Words: acne vulgaris, antibiotic resistance, benzoyl peroxide, anti-inflammatory, sub-antimicrobial dosing.

Abstract
With the rapidly increasing numbers of elders in North American Society, the prevalence of those living with dementia is clearly on the increase. According to the most recent document provided by the Alzheimer Society of Canada, The Rising Tide the growth in the numbers of those living with dementia will increase from 480,600 in 2008 (1.5% of Canada's population) to in the year 2038—1,125,200 people with dementia (2.8% of Canada's population).¹ All the challenges that Canadian society faces with this growing population merely mirror the enormous complexities that those living with dementia, their families and health care professional providers must increasingly contend with. Government policy makers must find ways to address this increasing population in which Dementia plays a prominent role. The result of the Supreme Court ruling on the Rasouli case has major potential implication for those facing the later stages of dementia and those under whose care members of this population will be entrusted.
Key Words: dementia, aging population, substitute decision makers.

Abstract
Hairy tongue, or known as lingua villosa, is a result of hypertrophy, elongation, and defective desquamation of the filiform papillae of the tongue. This condition may present in a variety of colors depending on the specific etiology. Etiologies of hairy tongue include poor oral hygiene, lack of mechanical stimulation and debridement of the tongue, the use of medications (especially broad-spectrum antibiotics), and therapeutic radiation of the head and the neck. This condition is also commonly seen in people having high consumption in coffee and tea, heavy use of tobacco, individuals addicted to drugs, patients who are HIV positive, and intravenous drug users. In most cases, non-pharmacologic interventions are used for the management of hairy tongue. Treatment involves brushing the tongue with a toothbrush or using a commercially available tongue scraper to retard the growth or to remove elongated filiform papillae. If Candida albicans is present, topical antifungal medications are used for patients who are symptomatic.
Key Words: Hairy tongue, Lingua villosa, Glossopyrosis, Halitosis.
