Q:

What are the symptoms of a bone island?

A:

Quick Answer

A bone island, technically known as enostosis, is usually asymptomatic, according to National Center for Biotechnology Information. Asymptomatic means enostosis has no known symptoms, and the condition reveals itself during a bone scan performed for other reasons. Bone islands are benign, notes Orthopaedics One.

Full Answer

Enostosis is marked by a spot of compact bone within that of spongy bone. The benign spot forms during the bone's development or congenitally, and bone islands are believed to occur during the layering of new bone tissue, notes Skeletal Radiology. Bone islands typically occur in the pelvis, femur, ribs and other long bones.

In radiological scans, bone islands appear as lesions between 2 millimeters and 2 centimeters in diameter, according to Orthopaedics One. MRIs typically show no destruction of surrounding tissues with regards to enostosis lesions. Doctors may monitor bone islands for growth later. If the spot enlarges 25 percent in six months or 50 percent in one year, a closer examination of the bone island may be needed.

Multiple bone islands in the same area are collectively called osteopoikilosis, notes Radiopaedia. Bone islands more than 2 centimeters in diameter are known as giant bone islands as these structures may show slow growth over time. Large enostoses may interfere with diagnosing malignancies in known cancer patients, and these large spots may be confused with other bony growths or bone tumors during the initial radiological scans.

    What is the diagnosis if liver spots are discovered during a CT scan?

    A:

    Possible diagnoses when spots are found on the liver during a computed tomography or CT scan are hepatocellular carcinoma or noncancerous conditions such as hemangioma, hyperplasia or hepatocellular adenoma, according to a study published on National Center for Biotechnology Information. A definitive diagnosis requires additional testing, a physical examination and thorough patient history.

    How long does it take to lose weight on Topamax?

    A:

    Topamax, formally known as topiramate, is not normally prescribed for weight loss, but rather as a medication for other conditions; although, it has been known to help patients achieve weight loss over the course that it has been prescribed, which can range anywhere from 2 to 4 weeks to 8.5 weeks, according to a paper published by the National Center for Biotechnology Information. Topiramate reaches peak levels in the body within 1.75 to 4.3 hours, and will begin to help with weight loss although results may not be noticed immediately. Depending on the treatment that topiramate was originally prescribed for, dosages range anywhere from 100 to 375mg per day with the average total weight loss being 22 pounds.

    How do you cure acid reflux, or GERD?

    A:

    Surgery corrects the underlying cause of GERD, according to the National Center for Biotechnology Information. It creates a barrier that prevents acid reflux and the progression of the disease into Barrett's esophagus. However, surgery is a last option for GERD as medication and lifestyle changes reduce symptoms, according to WebMD.
