Lumbar puncture is a common emergency department procedure used to obtain information about the cerebrospinal fluid (CSF) for diagnostic and, less commonly, therapeutic reasons. Please refer to the full article on Lumbar Puncture for more details on the lumbar puncture procedure. Lumbar puncture is typically performed via “blind” surface landmark guidance. The surface landmark technique is reported to be successful in a high percentage of attempted lumbar punctures; however, surface landmark identification of underlying structures has been shown to be accurate only 30% of the time. [1] Unsuccessful identification of proper landmarks often leads to increased difficulty in obtaining CSF, if the procedure is performed, and a higher rate of complications. Few alternatives are available in these cases. If available, fluoroscopic-guided lumbar puncture may be performed. If not, treatment is sometimes initiated empirically without obtaining CSF. Disadvantages of using fluoroscopy include limited availability or necessary transport of the patient outside of the emergency department, inability to directly visualize the spinal canal, and inherent radiation exposure
Claudication, which is defined as reproducible ischemic muscle pain, is one of the most common manifestations of peripheral arterial occlusive disease (PAOD) caused by atherosclerosis. Claudication occurs during physical activity and is relieved after a short rest. Pain develops because of inadequate blood flow.
During the examination, the doctor gently puts a lubricated, gloved finger of one hand into the rectum. He or she may use the other hand to press on the lower belly or pelvic area. A digital rectal exam is done for men as part of a complete physical examination to check the prostate gland .
The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam’s apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle. When the thyroid is its normal size, you can’t feel it.
When is endoscopy used? Endoscopes were first developed to look at parts of the body that couldn’t be seen any other way. This is still a common reason to use them, but endoscopy now has many other uses too. It’s often used in the prevention, early detection, diagnosis, staging, and treatment of cancer. To prevent and screen for cancer Some types of endoscopes are used to look for cancer in people who have no symptoms. For example, colonoscopy (KO-lun-AH-skuh-pee) and sigmoidoscopy (SIG-moid-AH-skuh-pee) are used to screen for colon and rectal cancer. These procedures can also help prevent cancer because they let doctors find and remove polyps (growths) that might become cancer if left alone. To find cancer early Endoscopy can sometimes be used to find cancer early, before it has had a chance to grow or spread. Looking for causes of symptoms When people go to the doctor with certain symptoms, endoscopy can sometimes be used to help find a cause. For instance: Laryngoscopy to look at the vocal cords in people with long-term hoarseness Upper endoscopy in people having trouble swallowing Colonoscopy in people with anemia (low red blood cell counts) with an unknown cause Colonoscopy in people with blood in their stool Looking at problems found on imaging tests Imaging tests such as x-rays and CT scans can sometimes show physical changes within the body. But these tests may only give information about the size, shape, and location of the problem. Doctors use endoscopes to see more details, like color and surface texture, when trying to find out what’s going on. Newer methods of endoscopy that include high magnification are being tested to find out whether they are more useful in detecting cancer and other abnormal cells on the inner surfaces of the body. To diagnose and find out the stage (extent) of cancer To get a tissue sample Going one step further, most types of endoscopes have tools on the end that the doctor can use to take out small tissue samples. This procedure is called a biopsy (BY-op-see). Samples can be taken from suspicious areas and then looked at under a microscope or tested in other ways to see if cancer is there. A biopsy is usually the best way to find out if a growth or change is cancer or something else. Getting a closer look In some cases endoscopes are used to help find out how far a cancer has spread. Thoracoscopy (THOR-uh-KAHS -kuh-pee) and laparoscopy (LAP-uh-RAHS-kuh-pee) can be very useful in finding out if cancer has spread into the thorax (chest) or abdomen (belly). The surgeon can look into these places making only a small incision (cut) in the skin.
This hormone, insulin, causes the liver to convert more glucose into glycogen (this process is called glycogenesis), and to force about 2/3 of body cells (primarily muscle and fat tissue cells) to take up glucose from the blood through the GLUT4 transporter, thus decreasing blood sugar.
Sed rate, or erythrocyte sedimentation rate ( ESR ), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it can help your doctor diagnose or monitor the progress of an inflammatory disease. ... Inflammation can cause the cells to clump.
An atrioventricular septal defect (AVSD) is a heart defect in which there are holes between the chambers of the right and left sides of the heart, and the valves that control the flow of blood between these chambers may not be formed correctly
Your doctor says your chest pain (angina) is caused by blockages in your heart arteries and that you need to get those blockages taken care of. What are your options? First, it's important to determine what type of angina you have. Different types of angina may need different treatments. Common types of angina are chronic stable angina — a type of angina that occurs when your heart is working hard — and unstable angina, which is new chest pain or chest pain that is getting worse. Other types of angina include variant angina — a rare type of angina caused by a spasm in the coronary arteries — and microvascular angina, which can be a symptom of disease in the small coronary artery blood vessels. Unstable angina is a serious situation and requires emergency treatment. Treatment for unstable angina involves hospitalization with medications to stabilize your condition. Some people with unstable angina may require a procedure called angioplasty (also known as percutaneous coronary intervention), usually combined with the placement of a small metal tube called a stent. In some cases of unstable angina, heart surgery (coronary bypass surgery) may be needed. Generally, if you have mild stable angina that is controlled by medications, you may not need further treatments. If you're experiencing symptoms of chronic stable angina even after taking medications and making lifestyle changes, or if you're at higher risk of serious heart disease, your doctor may recommend angioplasty or coronary bypass surgery. Making a decision on how to treat your angina can be difficult, but knowing the benefits and risks of stents and medications may help you decide.
Memory Loss & the Brain. It's not just a movement disorder. Besides causing tremors and other motion-related symptoms, Parkinson's disease affects memory, learning, and behavior. Parkinson's disease is notorious for so-called motor symptoms like muscle rigidity, tremor, slowed movement, and unsteady posture and gait.
If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.
In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
What is systemic lupus erythematosus? The immune system normally fights off dangerous infections and bacteria to keep the body healthy. An autoimmune disease occurs when the immune system attacks the body because it confuses it for something foreign. There are many autoimmune diseases, including systemic lupus erythematosus (SLE). The term lupus has been used to identify a number of immune diseases that have similar clinical presentations and laboratory features, but SLE is the most common type of lupus. People are often referring to SLE when they say lupus.
Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.
