An antisperm antibody test looks for special proteins (antibodies) that fight against a man's sperm in blood, vaginal fluids, or semen. The test uses a sample of sperm and adds a substance that binds only to affected sperm. Semen can cause an immune system response in either the man's or woman's body. The antibodies can damage or kill sperm. If a high number of sperm antibodies come into contact with a man's sperm, it may be hard for the sperm to fertilize an egg. The couple has a hard time becoming pregnant. This is called immunologic infertility.
Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.
When a stroke affects an extensive portion of the front and back regions of the left hemisphere, the result may be global aphasia. Survivors with global aphasia: May have great difficulty in understanding words and sentences. May have great difficulty in forming words and sentences. May understand some words. Get out a few words at a time. Have severe difficulties that prevent them from effectively communicating.
Women who have untreated chlamydia might develop pelvic inflammatory disease, which can cause ectopic pregnancies, chronic pelvic pain and infertility. ... The antibiotics used to treat chlamydia are safe in pregnancy and are used in pregnant women for many other types of infections.
Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst may enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms. Syringomyelia has several possible causes, though the majority of cases are associated with a condition in which brain tissue protrudes into your spinal canal (Chiari malformation). Other causes of syringomyelia include spinal cord tumors, spinal cord injuries and damage caused by inflammation around your spinal cord. If syringomyelia isn't causing any problems, monitoring the condition may be all that's necessary. But if you're bothered by symptoms, you may need surgery.
Reduction techniques can vary in terms of required force, time, equipment, and staff. [7] No single reduction method is successful in every instance; therefore, the clinician should be familiar with several reduction techniques. Techniques commonly used to reduce anterior shoulder dislocations include the following [35, 36, 37, 38, 39] : Stimson maneuver Scapular manipulation External rotation Milch technique Spaso technique Traction-countertraction
This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as persistent ventricular fibrillation/tachycardia). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.
Modern treatment of seizures started in 1850 with the introduction of bromides, which was based on the theory that epilepsy was caused by an excessive sex drive. In 1910, phenobarbital (PHB), which then was used to induce sleep, was found to have antiseizure activity and became the drug of choice for many years. A number of medications similar to PHB were developed, including primidone.
Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.
In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.
Traumatic Brain Injury (TBI) TBI is defined as an alteration in brain function, or other evidence of brain pathology, caused by an external force. Adopted by the Brain Injury Association Board of Directors in 2011. This definition is not intended as an exclusive statement of the population served by the Brain Injury Association of America. Acquired Brain Injury An acquired brain injury is an injury to the brain, which is not hereditary, congenital, degenerative, or induced by birth trauma. An acquired brain injury is an injury to the brain that has occurred after birth. There is sometimes confusion about what is considered an acquired brain injury. By definition, any traumatic brain injury (e.g. from a motor vehicle accident or assault) could be considered an acquired brain injury. In the field of brain injury, acquired brain injuries are typically considered any injury that is non traumatic. Examples of acquired brain injury include stroke, near drowning, hypoxic or anoxic brain injury, tumor, neurotoxins, electric shock or lightning strike.
While it is unclear whether high heel shoes may or may not cause back pain, it is common for high heels to exacerbate an already present spinal condition. ... This pain in the back may also result from foot or leg fatigue that results from wearing these shoes and this can affect whole body mechanics.
