Delivering Breech Baby
Delivering Breech Baby samer kareem 6,756 Views • 3 years ago

Most babies will move into delivery position a few weeks prior to birth, with the head moving closer to the birth canal. When this fails to happen, the baby’s buttocks and/or feet will be positioned to be delivered first. This is referred to as “breech presentation.” Breech births occur in approximately 1 out of 25 full-term births.

Almost all the cells in your body were produced by mitosis. The only exception is sperm or eggs which are produced by a different type of cell division called meiosis. During fertilization the sperm and egg unite to form a single cell called the zygote which contains chromosomes from both the sperm and egg.

Most times, a pulmonary embolism is caused by blood clots that travel from the legs or, rarely, other parts of the body (deep vein thrombosis, or DVT). Symptoms include shortness of breath, chest pain, and cough. Prompt treatment to break up the clot greatly reduces the risk of death. This can be done with blood thinners and drugs or procedures. Compression stockings and physical activity can help prevent clots from forming in the first place.

Neurotransmission
Neurotransmission samer kareem 1,510 Views • 3 years ago

Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.

Carpal Tunnel Release Procedure
Carpal Tunnel Release Procedure Surgeon 58,007 Views • 3 years ago

Carpal tunnel surgery, also called carpal tunnel release (CTR) and carpal tunnel decompression surgery, is a surgery in which the transverse carpal ligament is divided. It is a treatment for carpal tunnel syndrome and recommended when there is static (constant, not just intermittent) numbness, muscle weakness, or atrophy, and when night-splinting no longer controls intermittent symptoms of pain in the carpal tunnel. In general, milder cases can be controlled for months to years, but severe cases are unrelenting symptomatically and are likely to result in surgical treatment.

Hand Transplant Surgical Procedure
Hand Transplant Surgical Procedure samer kareem 2,146 Views • 3 years ago

Not every person who is missing a hand or upper limb might be eligible to receive a transplant. Many people are able to live full lives and accomplish everything they desire with the aid of a prosthetic device and sometimes without the aid of anything. However, some people find prosthetics difficult to use and the lack of sensory “feedback” from their prosthesis can significantly limit their function. These persons may consider reconstructive transplantation. We find that those patients who have either bilateral (both hands) amputations or those who have had their dominant hand amputated are likely to receive the most benefit from the procedure. However, we will provide information to any interested person regardless of the nature of their amputation.

Western Blot HIV Test
Western Blot HIV Test samer kareem 5,111 Views • 3 years ago

The window period is the time from infection until a test can detect any change. The average window period with HIV-1 antibody tests is 25 days for subtype B. Antigen testing cuts the window period to approximately 16 days and nucleic acid testing (NAT) further reduces this period to 12 days.[2] Performance of medical tests is often described in terms of: sensitivity: The percentage of the results that will be positive when HIV is present specificity: The percentage of the results that will be negative when HIV is not present. All diagnostic tests have limitations, and sometimes their use may produce erroneous or questionable results. False positive: The test incorrectly indicates that HIV is present in a non-infected person. False negative: The test incorrectly indicates that HIV is absent in an infected person.

Hypothyroidism
Hypothyroidism samer kareem 1,207 Views • 3 years ago

Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. The estimates vary, but approximately 10 million Americans have this common medical condition. In fact, as many as 10% of women may have some degree of thyroid hormone deficiency. Hypothyroidism is more common than you would believe, and millions of people are currently hypothyroid and don't know it.

Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]

Situs inversus is a condition in which the arrangement of the internal organs is a mirror image of normal anatomy. It can occur alone (isolated, with no other abnormalities or conditions) or it can occur as part of a syndrome with various other defects. Congenital heart defects are present in about 5-10% of affected people. The underlying cause and genetics of situs inversus are complex. Familial cases have been reported.[1][2]

A thin polymer film that seals surgical wounds could make sutures a relic of medical history.

Measuring just 50 microns, the film is placed on a surgical wound and exposed to an infrared laser, which heats the film just enough to meld it and the tissue, thus perfectly sealing the wound. Known as Surgilux, the device's raw material is extracted from crab shells and has Food and Drug Administration approval in the US

Waardenburg Syndrome
Waardenburg Syndrome samer kareem 2,270 Views • 3 years ago

Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. Although most people with Waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears. The hearing loss is present from birth (congenital). People with this condition often have very pale blue eyes or different colored eyes, such as one blue eye and one brown eye. Sometimes one eye has segments of two different colors. Distinctive hair coloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition. The features of Waardenburg syndrome vary among affected individuals, even among people in the same family.
