Chilblains, also known as pernio, is a medical condition in which damage occurs to capillary beds in the skin, most often in the hands or feet, when blood perfuses into the nearby tissue, resulting in redness, itching, inflammation, and possibly blisters.
In surgery or medical procedure, a ligature consists of a piece of thread (suture) tied around an anatomical structure, usually a blood vessel, another hollow structure or an accessory skin tag to shut it off.
Lamellar ichthyosis, also known as ichthyosis lamellaris and nonbullous congenital ichthyosis, is a rare inherited skin disorder, affecting around 1 in 600,000 people.
An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb to stabilize and hold anatomical structures—most often a broken bone, in place until healing is confirmed. It is similar in function to a splint.
Ainhum, also known as dactylolysis spontanea, is a painful constriction of the base of the fifth toe frequently followed by bilateral spontaneous autoamputation a few years later.
An ingrown nail, also known as onychocryptosis from Greek: ὄνυξ 'nail' and κρυπτός 'hidden', is a common form of nail disease. It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed. While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails, and for the most part are only problematic and painful on the big toe.
A periorbital hematoma, commonly called a black eye or a shiner, is bruising around the eye commonly due to an injury to the face rather than to the eye. The name refers to the dark-colored bruising which is the result of accumulated blood and fluid in the loose areolar tissue following a blow to the head. This blood tracks freely under the scalp producing a generalised swelling over the dome of the skull but cannot pass into either occipital or the temple regions because of the bony attachments of the occipitofrontalis muscle. But this fluid can, however, track forward into the eyelid because the occipitofrontalis muscle has no bony attachment anteriorly. This leads to formation of hematoma a few hours after the head injury or cranial operation. If injury is more extensive, potentially even a skull fracture, an apparent black eye can sometimes worsen and may require professional medical treatment before it will resolve. This is more likely if the area around both eyes has been injured or if there is a history of prior head injury or fracture around the eye. Though disfiguring, the vast majority of black eyes are not serious, require little or no treatment, and will resolve spontaneously within a week or two.
Meleda disease (MDM) or "mal de Meleda", also called Mljet disease, keratosis palmoplantaris and transgradiens of Siemens, is an extremely rare autosomal recessive congenital skin disorder in which dry, thick patches of skin develop on the soles of the hands and feet, a condition known as palmoplantar hyperkeratosis. Meleda Disease is a skin condition which usually can be identified not long after birth. This is a genetic condition but it is very rare. The hands and feet usually are the first to show signs of the disease but the disease can advance to other parts of the body. Signs of the disease include thickening of the skin, on hands and soles of feet, which can turn red in color. There currently is no cure and treatment is limited, but Acitretin can be used in severe cases.
Lymphangitis is an inflammation or an infection of the lymphatic channels that occurs as a result of infection at a site distal to the channel. It may present as long red streaks spreading away from the site of infection. It is a possible medical emergency as involvement of the lymphatic system allows for an infection to spread rapidly. The most common cause of lymphangitis in humans is bacteria, in which case sepsis and death could result within hours if left untreated. The most commonly involved bacteria include Streptococcus pyogenes and hemolytic streptococci. In some cases, it can be caused by viruses such as mononucleosis or cytomegalovirus, as well as specific conditions such as tuberculosis or syphilis, and the fungus Sporothrix schenckii. Lymphangitis is sometimes mistakenly called "blood poisoning". In reality, "blood poisoning" is synonymous with sepsis.
Fox–Fordyce disease is a chronic blockage of the sweat gland ducts with a secondary, non-bacterial inflammatory response to the secretions and cellular debris in the cysts. The inflammation is often accompanied by intense itching. In general, the disease often causes skin to darken near the affected area and raised bumps or papules to appear. In addition, hair follicles can become damaged which cause hair loss. Hidradenitis is very similar, but tends to have a secondary bacterial infection so that pus-draining sinuses are formed. It is a very devastating skin disease that does not have universally curative treatments.
Conidiobolomycosis is a rare long-term fungal infection that is typically found just under the skin of the nose, sinuses, cheeks and upper lips. It may present with a nose bleed or a blocked or runny nose. Typically there is a firm painless swelling which can slowly extend to the nasal bridge and eyes, sometimes causing facial disfigurement.
Monilethrix is a rare autosomal dominant hair disease that results in short, fragile, broken hair that appears beaded. It comes from the Latin word for necklace (monile) and the Greek word for hair (thrix). Hair becomes brittle, and breaks off at the thinner parts between the beads. It appears as a thinning or baldness of hair and was first described in 1897 by Walter Smith
Emergency bleeding control describes actions that control bleeding from a patient who has suffered a traumatic injury or who has a medical condition that has caused bleeding. Many bleeding control techniques are taught as part of first aid throughout the world. Other advanced techniques, such as tourniquets, are taught in advanced first aid courses and are used by health professionals to prevent blood loss by arterial bleeding. To manage bleeding effectively, it is important to be able to readily identify types of wounds and types of bleeding.
Jammed finger is a colloquialism referring to a variety of injuries to the joints of the fingers, resulting from axial loading beyond that which the ligaments can withstand. Common parts of the finger susceptible to this type of injury are ligaments, joints, and bones. The severity of the damage to the finger increases with the magnitude of the force exerted by the external object on the fingertip. Toes may become jammed as well, with similar results.
Klippel–Trénaunay syndrome, formerly Klippel–Trénaunay–Weber syndrome and sometimes angioosteohypertrophy syndrome and hemangiectatic hypertrophy, is a rare congenital medical condition in which blood vessels and/or lymph vessels fail to form properly. The three main features are nevus flammeus, venous and lymphatic malformations, and soft-tissue hypertrophy of the affected limb. It is similar to, though distinctly separate from, the less common Parkes Weber syndrome.
Prepubertal hypertrichosis, also known as childhood hypertrichosis, is a cutaneous condition characterized by increased hair growth, found in otherwise healthy infants and children. Prepubertal hypertrichosis is a cosmetic condition and does not affect any other health aspect. Individuals with this condition may suffer with low self esteem and mental health issues due to societal perceptions of what a "normal" appearance should be. The mechanism of prepubertal hypertrichosis is unclear, but causes may include genetics, systemic illnesses, or medications.
Cold injury is damage to the body from cold exposure, including hypothermia and several skin injuries. Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. Freezing cold injuries involve tissue damage when exposed to temperatures below freezing. Nonfreezing cold injuries involve tissue damage when exposed to temperatures often between 0-15 degrees Celsius for extended periods of time. While these injuries have disproportionally affected military members, recreational winter activities have also increased the risk and incidence within civilian populations. Additional risk factors include homelessness, inadequate or wet clothing, alcohol abuse or tobacco abuse, and pre-existing medical conditions that impair blood flow.
Constriction ring syndrome (CRS) is a congenital disorder with unknown cause. Because of the unknown cause there are many different, and sometimes incorrect names. It is a malformation due to intrauterine bands or rings that give deep grooves in, most commonly, distal extremities like fingers and toes. In rare cases the constriction ring can form around other parts of the fetus and cause amputation or even intrauterine death. The anatomy proximal to the site of constriction is developmentally normal. CRS can be associated with other malformations with club foot being most common. The precise configuration of the bands, lymphedema, and character of the amputations are not predictable and vary with each individual patient. Also, more than one extremity is usually affected, and it is rare for only one ring to present as an isolated malformation with no other manifestation of this syndrome.
A broken finger or finger fracture is a common type of bone fracture, affecting a finger. Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability.
Amplified musculoskeletal pain syndrome (AMPS) is an illness characterized by notable pain intensity without an identifiable physical cause.
