Gangrene: Death and putrefaction of tissue usually due to a loss of blood supply.Gas Gangrene: A severe condition resulting from bacteria invading healthy muscle from adjacent traumatized muscle or soft tissue. The infection originates in a wound contaminated with bacteria of the genus CLOSTRIDIUM. C. perfringens accounts for the majority of cases (over eighty percent), while C. noyvi, C. septicum, and C. histolyticum cause most of the other cases.Penile Diseases: Pathological processes involving the PENIS or its component tissues.Toes: Any one of five terminal digits of the vertebrate FOOT.Amputation: The removal of a limb or other appendage or outgrowth of the body. (Dorland, 28th ed)Clostridium perfringens: The most common etiologic agent of GAS GANGRENE. It is differentiable into several distinct types based on the distribution of twelve different toxins.Scrotum: A cutaneous pouch of skin containing the testicles and spermatic cords.Debridement: The removal of foreign material and devitalized or contaminated tissue from or adjacent to a traumatic or infected lesion until surrounding healthy tissue is exposed. (Dorland, 27th ed)Clostridium septicum: A species of gram-positive bacteria in the family Clostridiaceae. Infections have a strong association with malignancies and also with GAS GANGRENE.Fasciitis: Inflammation of the fascia. There are three major types: 1, Eosinophilic fasciitis, an inflammatory reaction with eosinophilia, producing hard thickened skin with an orange-peel configuration suggestive of scleroderma and considered by some a variant of scleroderma; 2, Necrotizing fasciitis (FASCIITIS, NECROTIZING), a serious fulminating infection (usually by a beta hemolytic streptococcus) causing extensive necrosis of superficial fascia; 3, Nodular/Pseudosarcomatous /Proliferative fasciitis, characterized by a rapid growth of fibroblasts with mononuclear inflammatory cells and proliferating capillaries in soft tissue, often the forearm; it is not malignant but is sometimes mistaken for fibrosarcoma.Ischemia: A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.Foot Ulcer: Lesion on the surface of the skin of the foot, usually accompanied by inflammation. The lesion may become infected or necrotic and is frequently associated with diabetes or leprosy.Calciphylaxis: Condition of induced systemic hypersensitivity in which tissues respond to appropriate challenging agents with a sudden local calcification.Leg: The inferior part of the lower extremity between the KNEE and the ANKLE.Genital Diseases, Male: Pathological processes involving the male reproductive tract (GENITALIA, MALE).Noma: A severe gangrenous process occurring predominantly in debilitated and malnourished children, especially in underdeveloped countries. It typically begins as a small vesicle or ulcer on the gingiva that rapidly becomes necrotic and spreads to produce extensive destruction of the buccal and labial mucosa and tissues of the face, which may result in severe disfigurement and even death. Various bacteria have been implicated in the etiology. (Dorland, 27th ed)Fingers: Four or five slender jointed digits in humans and primates, attached to each HAND.Toe Phalanges: Bones that make up the SKELETON of the TOES, consisting of two for the great toe, and three for each of the other toes.Lower Extremity: The region of the lower limb in animals, extending from the gluteal region to the FOOT, and including the BUTTOCKS; HIP; and LEG.Bromhexine: A mucolytic agent used in the treatment of respiratory disorders associated with viscid or excessive mucus. (From Martindale, The Extra Pharmacopoeia, 30th ed, p744)Skin UlcerArterial Occlusive Diseases: Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.Tibial Arteries: The anterior and posterior arteries created at the bifurcation of the popliteal artery. The anterior tibial artery begins at the lower border of the popliteus muscle and lies along the tibia at the distal part of the leg to surface superficially anterior to the ankle joint. Its branches are distributed throughout the leg, ankle, and foot. The posterior tibial artery begins at the lower border of the popliteus muscle, lies behind the tibia in the lower part of its course, and is found situated between the medial malleolus and the medial process of the calcaneal tuberosity. Its branches are distributed throughout the leg and foot.
