Obstetrics And Gynaecology
Obstetrics and Gynaecology (also spelled as Obstetrics and Gynecology; abbreviated as Obs and Gynae, O&G, OB-GYN and OB/GYN) is the medical specialty that encompasses the two subspecialties of obstetrics (covering pregnancy, childbirth, and the postpartum period) and gynecology (covering the health of the female reproductive system – vagina, uterus, ovaries, and breasts). Postgraduate training programs for both fields are usually combined, preparing the practising obstetrician-gynecologist to be adept both at the care of female reproductive organs' health and at the management of pregnancy, although many doctors go on to develop subspecialty interests in one field or the other. Scope United States According to the American Board of Obstetrics and Gynecology (ABOG), which is responsible for issuing OB-GYN certifications in the United States, the first step to OB-GYN certification is completing medical school to receive an MD or DO degree. From there doctors must complete a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papanicolaou Test
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), cervical smear (BE), cervical screening (BE), or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or colon (in both men and women). Abnormal findings are often followed up by more sensitive diagnostic procedures and, if warranted, interventions that aim to prevent progression to cervical cancer. The test was independently invented in the 1920s by Georgios Papanikolaou and Aurel Babeș and named after Papanikolaou. A simplified version of the test was introduced by Anna Marion Hilliard in 1957. A Pap smear is performed by opening the vagina with a speculum and collecting cells at the outer opening of the cervix at the transformation zone (where the outer squamous cervical cells meet the inner glandular endocervical cells), using an Ayre spatula or a cytobrush. A similar method is used to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scalp
The scalp is the anatomical area bordered by the human face at the front, and by the neck at the sides and back. Structure The scalp is usually described as having five layers, which can conveniently be remembered as a mnemonic: * S: The skin on the head from which head hair grows. It contains numerous sebaceous glands and hair follicles. * C: Connective tissue. A dense subcutaneous layer of fat and fibrous tissue that lies beneath the skin, containing the nerves and vessels of the scalp. * A: The aponeurosis called epicranial aponeurosis (or galea aponeurotica) is the next layer. It is a tough layer of dense fibrous tissue which runs from the frontalis muscle anteriorly to the occipitalis posteriorly. * L: The loose areolar connective tissue layer provides an easy plane of separation between the upper three layers and the pericranium. In scalping the scalp is torn off through this layer. It also provides a plane of access in craniofacial surgery and neurosurgery. This layer i ...

Traction (orthopedics)
Traction is a set of mechanisms for straightening broken bones or relieving pressure on the spine and skeletal system. There are two types of traction: skin traction and skeletal traction. They are used in orthopedic medicine. Techniques Traction procedures have largely been replaced by more modern techniques, but certain approaches are still used today: * Milwaukee brace * Bryant's traction *Buck's traction, involving skin traction. It is widely used for femoral fractures, low back pain, acetabular fractures and hip fractures.Skin Traction - Lower Extremity from University of Stellenbosch, Department of Orthopaedic Surgery.

Decapitation
Decapitation or beheading is the total separation of the head from the body. Such an injury is invariably fatal to humans and most other animals, since it deprives the brain of oxygenated blood, while all other organs are deprived of the involuntary functions that are needed for the body to function. The term ''beheading'' refers to the act of deliberately decapitating a person, either as a means of murder or as an execution; it may be performed with an axe, sword, knife, machete or by mechanical means such as a guillotine or chainsaw. An executioner who carries out executions by beheading is sometimes called a headsman. Accidental decapitation can be the result of an explosion, a car or industrial accident, improperly administered execution by hanging or other violent injury. Suicide by decapitation is rare but not unknown. The national laws of Saudi Arabia, Yemen, and Qatar permit beheading; however, in practice, Saudi Arabia is the only country that continues to behead i ...

Knife
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, a ...

Cranioclast
A cranioclast (from Greek κρανίον ''kranion'' "head, scull" and -κλάστης ''-klastes'' "breaker") is surgical instrument akin to a strong forceps. It was once used to crush and then extract the skull of a fetus so as to facilitate delivery in cases of obstructed labour. Pictures Image:Medical_Instruments_O&G_Cranioclast_open.jpg, Open Image:Medical_Instruments_O&G_Cranioclast_closed.jpg, Closed See also * Cephalotribe * Puerperal fever * Instruments used in general surgery There are many different surgical specialties, some of which require very specific kinds of surgical instruments to perform.

Cannula
A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 24 gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula (extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Many types of cannulas exist: Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula is a piece of plastic tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo
An embryo is an initial stage of development of a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres are arranged as a solid ball that when reaching a certain size, called a morula, takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating into the endometrial lining of the womb. Once implanted the embryo will continue its development through the next stages of gastrulation, neurulation, and organogenesis. Gastrulation is the formation of the three germ layers that will form all of the different parts of the body. Neurulation forms the nervous ...

Scissors
Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats. Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles. Terminology The noun ' ...
