Sjogren's Syndrome Symptoms
What are the symptoms of Sjogren's syndrome?
Symptoms of Sjogren's syndrome can involve the glands, as above, but there are also possible affects of the illness involving other organs of the body (extraglandular manifestations).
When the tear gland (lacrimal gland) is inflamed from Sjogren's, the resulting eye dryness can progressively lead to eye irritation, decreased tear production, "gritty" sensation, infection, and serious abrasion of the dome of the eye (cornea). Dry eyes can lead to infections of the eyes.
Inflammation of the salivary glands can lead to mouth dryness, swallowing difficulties, dental decay, gum disease, mouth sores and swelling, stones and/or infection of parotid gland inside of the cheeks. Dry lips often accompany the mouth dryness.
Other glands that can become inflamed, though less commonly, in Sjogren's syndrome include those of the lining of the breathing passages (leading to lung infections) and vagina (sometimes noted as pain during intercourse recurrent vaginal infections).
Extraglandular (outside of the glands) problems in Sjogren's syndrome include joint pain or inflammation (arthritis), Raynaud's phenomenon, lung inflammation, lymph-node enlargement, kidney, nerve, and muscle disease. A rare serious complication of Sjogren's syndrome is inflammation of the blood vessels (vasculitis), which can damage the tissues of the body that are supplied by these vessels.

What is Sjogren's syndrome?
Sjogren's syndrome is an autoimmune disease characterized by dryness of the mouth and eyes. Autoimmune diseases feature the abnormal production of extra antibodies in the blood that are directed against various tissues of the body. This particular autoimmune illness features inflammation in glands of the body that are responsible for producing tears and saliva. Inflammation of the glands that produce tears (lacrimal glands) leads to decreased water production for tears and dry eyes. Inflammation of the glands that produce the saliva in the mouth (salivary glands, including the parotid glands) leads to dry mouth and dry lips.
Sjogren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjogren's syndrome.
Sjogren's syndrome that is also associated with a connective tissue disease, such as
rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjogren's syndrome.
What causes Sjogren's syndrome?
While the exact cause of Sjogren's syndrome is not known, there is growing scientific support for genetic (inherited) factors. The genetic background of Sjogren's syndrome patients is an active area of research. The illness is sometimes found in other family members. It is also found more commonly in families that have members with other autoimmune illnesses, such as systemic lupus erythematosus, autoimmune thyroid disease, type I diabetes, etc. About 90% of patients with Sjogren's syndrome are female.

- prednisone, Deltasone, Liquid Pred - Defines the medication prednisone (Deltasone, Liquid Pred) a drug used for suppressing the immune system and inflammation. Article includes descriptions, uses, drug interaction, and side effects.
- Antinuclear Antibody Test - Read about antinuclear antibodies (ANAs), unusual antibodies that can bind to certain structures within the nucleus of the cells, are found in patients whose immune system may be predisposed to cause inflammation against their own body tissues. ANAs are indicative of the potential presence of an autoimmune illness.
- Rheumatoid Arthritis - Learn more about rheumatoid arthritis, an autoimmune disease that causes chronic joint inflammation, which has symptoms that include stiffness, fever, muscle and joint aches, loss of appetite, and fatigue. Treatment of rheumatoid arthritis incorporates the use of first-line drugs (aspirin and corticosteroids for pain and inflammation) and second-line drugs (methotrexate and hydroxychloroquine to prevent joint destruction and promote remission).

Dental X-Rays: When to Get Them »
What Types of Problems Can X-Rays Detect?
In adults, X-ray films can be used to:
- Show areas of decay that may not be visible with an oral examination,
especially small areas of decay between teeth
- Identify decay occurring beneath an existing filling
- Reveal bone loss that accompanies gum disease
- Reveal changes in the bone or in the root canal resulting from
infection
- Assist in the preparation of tooth implants, braces, dentures, or other
dental procedures
- Reveal abscesses (an infection at the root of a tooth or between the gum
and a tooth)
- Reveal other developmental abnormalities, such as cysts and some types of
tumors
In children, dental X-ray films are used to:
- Watch for decay
- Determine if there is enough space in the mouth to fit all incoming
teeth
- Determine if p...
