As a curious child, you might remember staring at an older relative's thick stockings at the blue, gnarled veins lying under the skin like bumpy snakes. Known as varicose veins, these blood vessels, which return blood from the legs to the heart, are actually a more superficial system. The real, working venous system for the legs lies deeper, says to Robert A. Weiss, MD, assistant professor of dermatology at the Johns Hopkins School of Medicine in Baltimore. This is good news, because it means that if the surface veins begin to clump up and bulge, they can be removed or destroyed without ruining circulation to the leg. The National Institutes of Health estimates that 60% of all men and women suffer from some form of vein disorder. A quarter of varicose vein sufferers are men, although Weiss notes that it is almost always women who seek help for spider veins.
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.
Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.
Methotrexate anti-tumor activity is a result of the inhibition of folic acid reductase, leading to inhibition of DNA synthesis and inhibition of cellular replication. The mechanism involved in its activity against rheumatoid arthritis is not known.
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.
Repairing a myelomeningocele in utero, rather than after birth, reduces the risk for fetal or neonatal death and the need for shunting by age 1 and substantially improves neurologic and motor outcomes. However, it is not without maternal and fetal risks. These are the findings, in a nutshell, of the long-awaited Management of Myelomeningocele Study (MOMS), which were published online February 9 in The New England Journal of Medicine.
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
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.
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.
Repair of post-infarction ventricular septal defect (VSD) remains a challenging procedure with a high risk of VSD recurrence. In order to reduce this risk, a double patch and glue technique was introduced in the department in 1986. This surgical technique is hereunder presented. Since 1971, ninety-three patients have been operated on early (≪15 days) after the occurrence of a post-infarction VSD. This retrospective study allows to compare the results of this double patch and glue technique to those obtained with the conventional one, in terms of hospital death and VSD recurrence. The double patch and glue technique avoids recurrence of VSD and plays a part in reducing hospital mortality.
Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza, commonly called the flu, is not the same as stomach "flu" viruses that cause diarrhea and vomiting. For most people, influenza resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include: Young children under 5, and especially those under 2 years Adults older than 65 Residents of nursing homes and other long-term care facilities Pregnant women and women up to two weeks postpartum People with weakened immune systems People who have chronic illnesses, such as asthma, heart disease, kidney disease and diabetes People who are very obese, with a body mass index (BMI) of 40 or higher Your best defense against influenza is to receive an annual vaccination.
Rhinoplasty enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. Rhinoplasty surgery can change: Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide, or upturned Nasal asymmetry
A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include
