Trench<unk>  Trench<unk>  is a medical condition caused by prolonged exposure of the feet to damp, unsanitary, and cold conditions. The use of the word trench in the name of this condition is a reference to trench warfare, mainly associated with World War I. Affected feet may become numb, affected by erythrosis (turning red) or cyanosis (turning blue) as a result of poor vascular supply, and feet may begin to have a decaying odour due to the possibility of the early stages of necrosis setting in. As the condition worsens, feet may also begin to swell. Advanced trench<unk>  often involves blisters and open sores, which lead to fungal infections; this is sometimes called tropical ulcer (jungle rot). If left untreated, trench<unk>  usually results in gangrene, which can cause the need for amputation. If trench<unk>  is treated properly, complete recovery is normal, though it is marked by severe short-term pain when feeling returns. As with other cold-related injuries, trench<unk>  leaves sufferers more susceptible to it in the future. Tropical<unk> <unk>  Tropical<unk> <unk>  (also known as "Paddy<unk> ", and "Paddy-field<unk> ") is a skin condition of the feet seen after continuous<unk>  of the feet in water or mud of temperature above for two to ten days. Warm water<unk> <unk>  Warm water<unk> <unk>  is a skin condition of the feet that results after exposure to warm, wet conditions for 48 hours or more and is characterized by maceration ("pruning"), blanching, and wrinkling of the soles, padding of toes (especially the big toe) and padding of the sides of the feet.<unk>  maceration occur whenever exposed for prolonged periods to moist conditions. Large watery blisters appear which are painful when they open and begin to peel away from the<unk>  itself. The heels, sides and bony prominences are left with large areas of extremely sensitive, red tissue, exposed and prone to infection. As the condition worsens, more blisters develop due to prolonged dampness which eventually covers the entire heel and/or other large, padded sections of the<unk> , especially the undersides as well as toes. Each layer in turn peels away resulting in deep, extremely tender, red ulcers. Healing occurs only when the feet are cleansed, dried and exposed to air for weeks. Scarring is permanent with dry, thin skin that appears red for up to a year or more. The padding of the feet returns but healing can be painful as the nerves repair with characteristics of diabetic neuropathy. Antibiotics and/or antifungal are sometimes prescribed.<unk> <unk>  is a common problem with homeless individuals wearing one pair of socks and shoes for extensive periods of time, especially wet shoes and sneakers from rain and snow. The condition is exacerbated by excessive dampness of the feet for prolonged periods of time. Fungus and bacterial infections prosper in the warm, dark, wet conditions and are characterized by a sickly odor that is distinct to<unk> <unk> .
