Bone marrow examination refers to the pathologic analysis of samples of bone marrow obtained by bone marrow biopsy (often called a trephine biopsy) and bone marrow aspiration. Bone marrow examination is used in the diagnosis of a number of conditions, including leukemia, multiple myeloma, anemia, and pancytopenia. The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells. While much information can be gleaned by testing the blood itself (drawn from a vein by phlebotomy), it is sometimes necessary to examine the source of the blood cells in the bone marrow to obtain more information on hematopoiesis; this is the role of bone marrow aspiration and biopsy.
Before deciding how to treat one episode of high blood glucose, it is important to figure out why the number is high. Some possible causes include eating a heavy meal, not getting enough physical activity, forgetting to take diabetes medication, and dealing with illness and stress. Insulin is the medication that will bring blood glucose down the fastest. Someone who uses mealtime insulin can take correction doses to lower blood glucose. This requires a thorough understanding of when to inject, how often to give correction doses, and how much insulin to use. You will need to work with your doctor or diabetes educator to learn how to do this. Apart from administering insulin, the fastest way to lower your blood glucose is to engage in physical activity. Exercise results in an increased sensitivity to insulin. It causes your muscle cells to take up more glucose, leaving less of it to circulate in your bloodstream during and after the physical activity (which means a lower blood glucose when you test). Frequent, regular exercise is very important to good blood glucose control no matter what type of diabetes you have. Research has shown that it is vital in warding off long-term complications like neuropathy, retinopathy, and heart and kidney diseases. Don't forget to check with a doctor, though, before making any major changes to your exercise routine. And, if you have type 1 diabetes and your glucose is 250 mg/dl or higher, check for urine ketones. You should not exercise if ketones are present.
Colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine (rectum and colon). He or she uses a thin, flexible tube called a colonoscope to look at the colon. A colonoscopy helps find ulcers, colon polyps, tumors, and areas of inflammation or bleeding.
Pinch air out of the tip of the condom. Unroll condom all the way down the penis. After sex but before pulling out, hold the condom at the base. Then pull out, while holding the condom in place. Carefully remove the condom and throw it in the trash.
Restrictive cardiomyopathy (RCM) is a rare form of heart muscle disease that is characterized by restrictive filling of the ventricles. In this disease the contractile function (squeeze) of the heart and wall thicknesses are usually normal, but the relaxation or filling phase of the heart is very abnormal.
A giant abdominal wall hernia can develop from an existing ventral or incisional hernia, sometimes arising after one or more failed repair attempts. These hernias may also result from a traumatic injury where the abdomen was required to be left open and healing was delayed. In giant abdominal wall hernias, multiple loops of intestines and sometimes other abdominal organs reside within the hernia sac. The abdominal wall muscles then become conditioned to this and retract reducing the available space inside the abdomen.
A chalazion is a swollen bump on the eyelid. It happens when the eyelid’s oil gland clogs up. It may start as an internal hordeolum (stye). At first, you might not know you have a chalazion as there is little or no pain. But as it grows, your eyelid may get red, swollen, and sometimes tender to touch. If the chalazion gets large, it can press on your eye and cause blurry vision. Rarely, the whole eyelid might swell.
