How can we prevent and diagnose Osteoporosis

May 17th, 2010

To reach optimal peak bone mass and continue building new bone tissue as you age, you should consider several factors.
- Calcium: An inadequate supply of calcium over a lifetime contributes to the development of osteoporosis. Food sources of calcium include low-fat dairy products, such as milk, yogurt, cheese, and ice cream; dark green, leafy vegetables, such as broccoli, collard greens, bok choy, and spinach; sardines and salmon with bones; tofu; almonds; and foods fortified with calcium, such as orange juice, cereals, and breads.
- Vitamin D: Vitamin D plays an important role in calcium absorption and bone health. It is synthesized in the skin through exposure to sunlight. Food sources of vitamin D include egg yolks, saltwater fish, and liver.
- Smoking: Women who smoke have lower levels of estrogen compared with nonsmokers, and they often go through menopause earlier. Smokers also may absorb less calcium from their diets.
- Exercise: Like muscle, bone is living tissue that responds to exercise by becoming stronger. Weight-bearing exercise is the best for your bones because it forces you to work against gravity.
- Alcohol: Regular consumption of 2 to 3 ounces a day of alcohol may be damaging to the skeleton, even in young women and men.
- Medications that cause bone loss: The long-term use of glucocorticoids (medications prescribed for a wide range of diseases, including arthritis, asthma, Crohn’s disease, lupus, and other diseases of the lungs, kidneys, and liver) can lead to a loss of bone density and fracture.

Diagnosis of Osteoporosis

Women who have had a fracture due to fragility are diagnosed with severe osteoporosis and have a high risk for another fracture. Early diagnosis can prevent fractures and slow deterioration of bone tissue.
If the doctor suspects osteoporosis, a bone scan would be suggested. – A common test that measures bone density is called a dual energy X-ray absorptiometry (DEXA). This test measures the density of the bones in your hips, spine and wrist, which are all places likely to be affected by osteoporosis.
- Quantitative computed tomography (QCT) measures bone density in the hip and spine and produces a three-dimensional image that shows true volume density. QCT has the capacity to isolate an area for testing. The radiation level in QCT is 10 times higher than in DEXA.
- Peripheral bone density testing uses ultrasound to identify bone loss in a localized area such as the heel or hand.
Doctor may also order an ultrasound or a computerized tomography (CT) scan to help check the density of your bones.

Diagnosis and treatment of Cystitis

May 11th, 2010

The term ‘cystitis’ refers to inflammation of the urinary bladder. The recurrence of cystitis may, in some cases, be associated with kidney troubles. Children and men should always see their GP if they have cystitis. Women should always see their GP the first time they have the condition. They should also return to see their GP if they have the condition more than three times in one year.The symptoms of cystitis usually clear up without treatment within 4-9 days. There are some self-help treatments that can ease the discomfort of any symptoms, or your GP may prescribe antibiotics.

- Over-the-counter (OTC) painkillers, such as paracetamol, or ibuprofen, can be taken to reduce discomfort.
- Drinking plenty of water is often recommended as a treatment for cystitis.
- If your symptoms are moderate, or severe, your GP may prescribe a short course of antibiotics. This will usually be in the form of a tablet to be swallowed 2-4 times a day, for three days.
- For a more complicated case of cystitis, such as cystitis with another underlying infection, you may be given antibiotics to take for 5-10 days.

How does a doctor diagnose cystitis?

The diagnosis of cystitis is primarily based on symptoms and signs. Visual appearance of the urine is not helpful. The most important examination of urine is done by chemical testing (dipstick test), which is very quick, and by urine culture where the specimen is sent to a hospital laboratory to grow and examine the bacteria. The specimen must be fresh. It is also important that the woman has separated her labia (lips) during urination, to avoid bacteria from the skin and vagina contaminating the specimen. If there is inflammation, the doctor will identify bacteria and red and white blood cells in the urine using the dipstick test. If this is positive, your doctor can prescribe antibiotics immediately while waiting for further confirmation from the urine culture.

How is staging determined for thyroid cancer?

May 3rd, 2010

If the diagnosis is thyroid cancer, the doctor needs to know the stage, or extent, of the disease to plan the best treatment. Staging is a careful attempt to learn whether the cancer has spread and, if so, to what parts of the body.
Staging is based on the results of the physical exam, biopsy, and imaging tests, ultrasound, CT scan, MRI, chest x-ray, and/or nuclear medicine scans.
The TNM method is the most universally used staging method and applies to both papillary and follicular thyroid cancers.
- T indicates the size of the main (primary) tumor and whether it has grown into nearby areas.
- N describes the extent of spread to nearby (regional) lymph nodes. Lymph nodes are small bean-shaped collections of immune system cells that are important in fighting infections. Cells from thyroid cancers can travel to lymph nodes in the neck and chest areas.
- M indicates whether the cancer has spread (metastasized) to other organs of the body. If there is distant metastases, M = 1, if the cancer has not spread outside of the neck region, M = 0.

Based on these three categories, the cancer is assigned a Stage of 1, 2, 3 or 4. Stage 1 is the least advanced form of cancer with the best prognosis, and Stage 4 is the most advanced category.
