Senile pruritus is one of the most common conditions in the elderly or people over 65 years of age with an emerging itch that may be accompanied with changes in temperature and textural characteristics. [1] [2] [3] In the elderly, xerosis, is the most common cause for an itch due to the degradation of the skin barrier over time. [4]
Skin ulcers appear as open craters, often round, with layers of skin that have eroded. The skin around the ulcer may be red, swollen, and tender. Patients may feel pain on the skin around the ulcer, and fluid may ooze from the ulcer. In some cases, ulcers can bleed and, rarely, patients experience fever. Ulcers sometimes seem not to heal ...
Chronic wound exudate contains proteolytic enzymes and other components that degrade skin integrity and predispose it to inflammation. [8] [9] Moisture-associated skin damage can also be caused by bodily fluids or other contaminants that enter the periwound areas, for example, in patients with urinary or fecal incontinence, or colostomy ...
Certain characteristic features of the pathology seen point toward Crohn's disease; it shows a transmural pattern of inflammation, meaning the inflammation may span the entire depth of the intestinal wall. [1] Granulomas, aggregates of macrophage derivatives known as giant cells, are found in 50% of cases and are most specific for Crohn's disease.
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
Shearing is a separation of the skin from underlying tissues. When a patient is partially sitting up in bed, skin may stick to the sheet, making the skin susceptible to shearing in case underlying tissues move downward with the body toward the foot of the bed. This may also be possible on a patient who slides down while sitting in a chair.

Additionally, due to the natural processes of aging, the skin of geriatric patients has impaired mechanisms to protect against burns, including impaired neurosensory sensitivity, skin permeability, and regeneration capacity. These impairments lead to deeper wounds, prolonged wound healing, and lower potential for complete recovery.
