Clubfoot
Clubfoot is a congenital or acquired defect where one or both feet are rotated inward and downward. Congenital clubfoot is the most common congenital malformation of the foot with an incidence of 1 per 1000 births. In approximately 50% of cases, clubfoot affects both feet, but it can present unilaterally causing one leg or foot to be shorter than the other. Most of the time, it is not associated with other problems. Without appropriate treatment, the foot deformity will persist and lead to pain and impaired ability to walk, which can have a dramatic impact on the quality of life. The exact cause is usually not identified. Both genetic and environmental factors are believed to be involved. There are two main types of congenital clubfoot: idiopathic (80% of cases) and secondary clubfoot (20% of cases). The idiopathic congenital clubfoot is a multifactorial condition that includes environmental, vascular, positional, and genetic factors. There appears to be hereditary component ...

Distal Arthrogryposis
Arthrogryposis (AMC) describes congenital joint contracture in two or more areas of the body. It derives its name from Greek, literally meaning 'curving of joints' (', 'joint'; ', late Latin form of late Greek ', 'hooking'). Children born with one or more joint contractures have abnormal fibrosis of the muscle tissue causing muscle shortening, and therefore are unable to perform active extension and flexion in the affected joint or joints. AMC has been divided into three groups: amyoplasia, distal arthrogryposis, and syndromic (is a syndrome or part of a syndrome). Amyoplasia is characterized by severe joint contractures and muscle weakness. Distal arthrogryposis mainly involves the hands and feet. Types of arthrogryposis with a primary neurological or muscle disease belong to the syndromic group. Signs and symptoms Often, every joint in a patient with arthrogryposis is affected; in 84% all limbs are involved, in 11% only the legs, and in 4% only the arms are involved. Every join ...

Tutankhamun
Tutankhamun or Tutankhamen, (; ), was an Egyptian pharaoh who ruled during the late Eighteenth Dynasty of Egypt, Eighteenth Dynasty of ancient Egypt. Born Tutankhaten, he instituted the restoration of the traditional polytheistic form of ancient Egyptian religion, undoing a previous shift to the religion known as Atenism. Tutankhamun's reign is considered one of the greatest restoration periods in ancient Egyptian history. His endowments and restorations of cults were recorded on what is today known as the Restoration Stela. The cult of the god Amun at Thebes, Egypt, Thebes was restored to prominence, and the royal couple changed their names to "Tutankhamun" and "Ankhesenamun", replacing the -aten suffix. He also moved the royal court from Akhenaten's capital, Amarna, back to Memphis, Egypt, Memphis almost immediately on his accession to the kingship. He reestablished diplomatic relations with the Mitanni and carried out military campaigns in Nubia and the Near East. Tutankh ...

Amniocentesis
Amniocentesis is a medical procedure used primarily in the prenatal diagnosis of genetic conditions. It has other uses such as in the assessment of infection and fetal lung maturity. Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis being the gold-standard procedure after 15 weeks' gestation. In this procedure, a thin needle is inserted into the abdomen of the pregnant woman. The needle punctures the amnion, which is the membrane that surrounds the developing fetus. The fluid within the amnion is called amniotic fluid, and because this fluid surrounds the developing fetus, it contains fetal cells. The amniotic fluid is sampled and analyzed via methods such as karyotyping and DNA analysis technology for genetic abnormalities. An amniocentesis is typically performed in the second trimester between the 15th and 20th week of gestation. Women who choose to have this test are prima ...

Smoking And Pregnancy
Tobacco smoking during pregnancy causes many detrimental effects on health and reproduction, in addition to the general health effects of tobacco. A number of studies have shown that tobacco use is a significant factor in miscarriages among pregnant smokers, and that it contributes to a number of other threats to the health of the foetus. Because of the associated risks, people are advised not to smoke before, during or after pregnancy. If this is not possible, however, reducing the daily number of cigarettes smoked can minimize the risks for both the mother and child. This is especially true for people in developing countries, where breastfeeding is essential for the child's overall nutritional status. Smoking before pregnancy Women who are pregnant or planning to become pregnant are advised to stop smoking. It is important to examine these effects because smoking before, during and after pregnancy is not an unusual behavior among the general population and can have detrimental ...

Metatarsus Adductus
Pigeon toe, also known as in-toeing, is a condition which causes the toes to point inward when walking. It is most common in infants and children under two years of age and, when not the result of simple muscle weakness, normally arises from underlying conditions, such as a twisted shin bone or an excessive anteversion (femoral head is more than 15° from the angle of torsion) resulting in the twisting of the thigh bone when the front part of a person's foot is turned in. Causes The cause of in-toeing can be differentiated based on the location of the misalignment. The variants are: * Curved foot (metatarsus adductus) * Twisted shin (tibial torsion) * Twisted thighbone (femoral anteversion) Metatarsus adductus This is the most common form of being pigeon toed, when the feet bend inward from the middle part of the foot to the toes. This is the most common congenital foot abnormality, occurring every 1 in 5,000 births. The rate of metatarsus adductus is higher in twin pregnan ...

Māori People
Māori () are the Indigenous peoples of Oceania, indigenous Polynesians, Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of Māori migration canoes, canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed Māori culture, a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Early contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi, Treaty of Waitangi/Te Tiriti o Waitangi in 1840, the two cultures coexisted for a generation. Rising ten ...

Ultrasound
Ultrasound is sound with frequency, frequencies greater than 20 Hertz, kilohertz. This frequency is the approximate upper audible hearing range, limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of String instrument ...

Orthopedic Casting
An orthopedic cast, commonly referred to simply as a cast, is a form of medical treatment used to immobilize and support bones and soft tissues during the healing process after fractures, surgeries, or severe injuries. By restricting movement, casts provide stability to the affected area, enabling proper alignment and healing of bones, ligaments, and tendons. They are commonly applied to the limbs but can also be used for the trunk, neck, or other parts of the body in specific cases. Orthopedic casts come in various types and designs, tailored to the nature and severity of the injury, as well as the patient's needs. Advances in medical techniques have made casts more comfortable, effective, and versatile, allowing for both weight-bearing and non-weight-bearing options. Upper extremity casts Upper extremity casts are frequently utilized to immobilize the arm, wrist, or hand for the treatment of fractures, soft tissue injuries, or during post-surgical recovery. They offer stabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developing World
A developing country is a sovereign state with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries. There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthopedics
Orthopedic surgery or orthopedics (American and British English spelling differences, alternative spelling orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal Physical trauma, trauma, Spinal disease, spine diseases, Sports injury, sports injuries, degenerative diseases, infections, tumors and congenital disorders. Etymology Nicholas Andry coined the word in French as ', derived from the Ancient Greek words ("correct", "straight") and ("child"), and published ''Orthopedie'' (translated as ''Orthopædia: Or the Art of Correcting and Preventing Deformities in Children'') in 1741. The word was Assimilation (linguistics), assimilated into English as ''orthopædics''; the Typographic ligature, ligature ''æ'' was common in that era for ''ae'' in Greek- and Latin-based words.

Han Chinese
The Han Chinese, alternatively the Han people, are an East Asian people, East Asian ethnic group native to Greater China. With a global population of over 1.4 billion, the Han Chinese are the list of contemporary ethnic groups, world's largest ethnic group, making up about 17.5% of the world population. The Han Chinese represent 91.11% of the population in China and 97% of the population in Taiwan. Han Chinese are also a significant Overseas Chinese, diasporic group in Southeast Asian countries such as Thailand, Malaysia, and Indonesia. In Singapore, people of Han Chinese or Chinese descent make up around 75% of the country's population. The Han Chinese have exerted a primary formative influence in the development and growth of Chinese civilization. Originating from Zhongyuan, the Han Chinese trace their ancestry to the Huaxia people, a confederation of agricultural tribes that lived along the middle and lower reaches of the Yellow River in the north central plains of Chin ...
