Pseudo-ainhum
Ainhum (from Portuguese, ), 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. Signs and symptoms The groove begins on the lower and internal side of the base of the fifth toe, usually according to the plantar-digital fold. The groove becomes gradually deeper and more circular. The rate of spread is variable, and the disease may progress to a full circle in a few months, or still be incomplete after years. In about 75 percent of cases both feet are affected, though not usually to the same degree. There is no case reported where it begins in any other toe than the fifth, while there is occasionally a groove on the fourth or third toe. The distal part of the toe swells and appears like a small potato. The swelling is due to lymphatic edema distal to the constriction. After a time crusts can appear in the groove which can be infected with staphylococcus. While the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Syringomyelia
Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. Often, syringomyelia is used as a generic term before an etiology is determined. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in loss of feeling, paralysis, weakness, and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands. It may also lead to a cape-like bilateral loss of pain and temperature sensation along the upper chest and arms. The combination of symptoms varies from one patient to another depending on the location of the syrinx within the spinal cord, as well as its extent. Syringomyelia has a prevalence estimated at 8.4 cases per 100,000 people, with symptoms usually beginning in young adulthood. Signs of the disorder tend to develop slowly, although sudden onset may occur with coughing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dermal And Subcutaneous Growths
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.). Saunders. Pages 1, 11–12. . The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix.Marks, James G; Miller, Jeffery (2006). ''Lookingbill and Marks' Principles of Dermatology'' (4th ed.). Elsevier Inc. Page 8–9. . It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, swe ...

Foot Diseases
Diseases of the foot generally are not limited, that is they are related to or manifest elsewhere in the body. However, thfootis often the first place some of these diseases or a sign or symptom of others appear. This is because of the foot's distance from the central circulation, the heart and its constant exposure to pressures from the ground and the weight of the body. Thfootmay is a complex structure with 26 bones, 33 joints, numerous muscles, nerves and different ligament types. Any part of the foot can be affected by diseases, with symptoms ranging from mild aches to more serious pain hindering one's ability to walk or bear weight. Most minor cases of foot pain can be responded to by home care treatments. However, when severe pain is present, medical attention is required as it is a disabling condition. If foot pain is not treated in time, it can lead to long-term disability and continuing damage to the foot. Causes The most common cause of foot pain is wearing ill ...

Yaws
Yaws is a tropical infection of the skin, bones, and joints caused by the spirochete bacterium ''Treponema pallidum pertenue''. The disease begins with a round, hard swelling of the skin, in diameter. The center may break open and form an ulcer. This initial skin lesion typically heals after 3–6 months. After weeks to years, joints and bones may become painful, fatigue may develop, and new skin lesions may appear. The skin of the palms of the hands and the soles of the feet may become thick and break open. The bones (especially those of the nose) may become misshapen. After 5 years or more, large areas of skin may die, leaving scars. Yaws is spread by direct contact with the fluid from a lesion of an infected person. The contact is usually nonsexual. The disease is most common among children, who spread it by playing together. Other related treponemal diseases are bejel (''T. pallidum endemicum''), pinta (''T. carateum''), and syphilis (''T. p. pallidum''). The appearan ...

Epidemiological Society Of London
The Epidemiological Society of London was a British medical society founded in 1850 with the objective of investigating the causes and conditions which influence the origin, propagation, mitigation, and prevention of epidemic disease. In 1907 it merged with the Royal Medical and Chirurgical Society of London and became a part of the Royal Society of Medicine as the Epidemiological Section and then Epidemiology and Public Health section. __TOC__ History Following a severe outbreak of cholera in England in 1831-32 a London physician, J.H.Tucker, proposed in a letter to the ''Lancet'' that a society should be formed to specifically study epidemics.

At a follow-up meeting in July, chaired by Sir Astley Cooper, a constitution was agreed and officers appointed. Benjamin Guy Babington, a Guy's Hospital physician, was elected as the first president of the society, whose agreed o ...

Z-plasty
Z-plasty is a versatile plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. It can elongate a contracted scar or rotate the scar tension line. The middle line of the Z-shaped incision (the central element) is made along the line of the greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and then transposed. The length and angle of each flap are usually the same to avoid mismatched flaps that may be difficult to close. Some possible complications of Z-plasty include flap necrosis, Hematoma, haematoma (blood clot) formation under the flaps, wound infection, trapdoor effect and sloughing (necrosis) of the flap caused by wound tension and inadequate blood supply. Classification Z-plasties can be functional (elongate and relax scars) or cosmetic (realign scars to make them less noticeable). They can be single or multiple. Variations include skew and planimetric Z-plasties. Technique The tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
