Hello: You are referring to Sjögren's syndrome, also known as xerostomia, which is a chronic inflammatory disease of the exocrine glands and is classified as an autoimmune disorder.
The main symptoms include dry eyes and dry mouth, with other common symptoms such as joint pain, dryness in other skin areas, difficulty swallowing, and interstitial lung disease.
Some patients may have concurrent autoimmune diseases, referred to as secondary Sjögren's syndrome.
For patients diagnosed with this condition, long-term follow-up is necessary to monitor for the development of other autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma.
These patients also have a higher risk of developing lymphoma, which requires special attention.

In terms of treatment, commonly used immunomodulators include hydroxychloroquine, and sometimes corticosteroids may be added.
Symptomatic treatments such as Salagen can promote glandular secretion.
The most important aspect is to adjust daily lifestyle and dietary habits to maintain a good quality of life.
It is crucial to be aware that a minority of patients may develop interstitial lung disease, which can progress to pulmonary fibrosis and affect life expectancy.
Overall, the prognosis for this condition is generally good and does not affect life expectancy, but it is essential to have regular follow-up and treatment with a rheumatologist.
Wishing you good health.

Lin Hsiao-Yi, Department of Allergy, Immunology, and Rheumatology, Taipei Veterans General Hospital.

Blount's disease, also known as tibia vara, is a growth disorder that affects the shinbone (tibia) in children. It is characterized by an abnormal inward angulation of the tibia, leading to bowing of the legs. This condition can occur in one leg or both legs and is most commonly seen in children who are overweight or those who have a family history of the disease. The exact cause of Blount's disease is not fully understood, but it is believed to be related to abnormal growth and development of the tibia, particularly in the growth plate.

Blount's disease is not considered a terminal condition. It is a treatable disorder, and early intervention is crucial for the best outcomes. Treatment options vary depending on the severity of the condition and the age of the child. In mild cases, observation and monitoring may be sufficient, especially in younger children whose bones are still growing. However, if the bowing is severe or progressive, treatment may involve the use of braces or surgical intervention.

Bracing is often recommended for younger children, as it can help guide the growth of the tibia and correct the bowing. In cases where bracing is ineffective or if the child is older and the growth plates are closing, surgical options may be considered. Surgical procedures can include osteotomy (cutting and realigning the bone) or guided growth surgery, which involves placing plates or screws to control the growth of the bone.

It is important to note that while Blount's disease can lead to complications such as knee pain or arthritis if left untreated, it is not a life-threatening condition. With appropriate treatment, most children with Blount's disease can achieve normal leg alignment and function. Regular follow-up with a pediatric orthopedic specialist is essential to monitor the condition and adjust treatment as necessary.

In summary, Blount's disease is a manageable condition that requires medical attention but is not classified as a terminal illness. Early diagnosis and treatment can lead to positive outcomes, allowing children to lead active and healthy lives. If you suspect that a child may have Blount's disease, it is important to consult with a healthcare professional for a proper evaluation and treatment plan.
