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.
It may be reassuring to know spotting or bleeding after sex is common and can come from the vagina, cervix, or urinary tract. It occurs most commonly in women 20 to 40 years old. Cervical Cancer: A very rare cause of spotting. ... Vaginal Dryness: Often caused by inadequate foreplay or vaginal lubrication.

You get a shot with a needle that has infected blood on it. ... You get a tattoo or a piercing with a needle that has infected blood on it.
Our results in this study of MIPO treated with conventional plates are comparable to the results of the femoral shaft fractures treated with intramedullary nailing. The technique can be used for all femoral shaft fractures. Although the biomechanics of the plate fixation are less stable compared to the intamedullary nail, the mechanical stability is stable enough for bone healing. Healing was rapid, and postoperative care was simplified. The two major complications were malalignment and screw breakage. We recommend using at least three separated screws in each fragment to prevent stress on the screw and screw breakage. Intraoperative limb length, axial alignment, and rotation must be carefully assessed to prevent malalignment. The limitations of our study include lack of a comparison group, retrospective data collection, and no randomisation in outcome evaluation
At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may result when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

Unlike the messy, old-fashioned neti pot or competitors with badly-designed, backflow-prone squeeze bottles that can cause sinus infection, NasalCare’s patented NasalCare® Nasal Rinse System ensures comfortable and effective delivery throughout the nasal passages, preventing sinus infection, allergy and post nasal drip. A soothing mix of sea salt and Aloe Vera extract washes away nasal irritants and the common causes of colds and flu while providing nasal congestion relief via our nasal wash. NasalCare also acts as a sinus rinse for allergy treatment. Though used for centuries in the Orient as a natural remedy and preventative measure for all sinus conditions, nasal irrigation is just catching on here. Catch us now and stop catching colds and the flu! Learn more at: http://www.nasalcleanse.com/index.html.
A vasectomy is a simple surgery done by a doctor in an office, hospital, or clinic. The small tubes in your scrotum that carry sperm are cut or blocked off, so sperm can’t leave your body and cause pregnancy. The procedure is very quick, and you can go home the same day. And it’s extremely effective at preventing pregnancy — almost 100%
A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.
Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.
Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.
A hematoma is a collection of blood outside of a blood vessel. There are several types of hematomas and they are often described based on their location. Examples of hematomas include subdural, spinal, under the finger or toenail bed (subungual), ear, and liver (hepatic). Some causes of hematomas are as pelvic bone fractures, fingernail injuries (subungual), bumps, passing blood clots, blood clot in the leg (DVT), blood cancers, and excessive alcohol use. Symptoms of hematomas depend upon their location and whether adjacent structures are affected by the inflammation and swelling associated with the bleeding and may include
