Some issues Dr. Joseph N. Sidari, MD can help you with:

Subcutaneous Allergen Immunotherapy (Allergy Shots)

Also known as allergy shots, subcutaneous allergen immunotherapy is a treatment in which gradually increasing doses of an allergen are injected under the skin. An allergen is a substance that can bring about an allergic reaction. Pollen, dust mites, and pet dander are the most common examples of these substances. When patients receive an allergy shot, their body produces "blocking" antibodies that decrease the immune system's sensitivity to an allergen, thus reducing their symptoms.

Before treatment is begun, patients and their doctors first have to identify different factors that trigger their symptoms. Then, skin tests are done to confirm which substances cause allergic reactions. Blood tests may be performed as well, but they are typically not necessary.

There are two phases to subcutaneous allergen immunotherapy: a build-up phase and a maintenance phase. The build-up phase lasts three to six months, during which patients receive shots with increasing amounts of the allergens once or twice a week. When the effective dose is reached, the maintenance phase begins and may continue for up to five years.

Although allergy shots are the longest-lasting and most effective allergy treatment available, they are not for everyone. If patients have heart problems, high blood pressure, or severe asthma, they should not be given allergy shots. The injections are generally safe, but they may have a little swelling at the injection site, which is normal. Rarely, severe shock-like reactions, called anaphylaxis, can also occur. Patients will likely be required by their doctor to stay for half an hour after their shot, so in the event of an anaphylactic reaction, it can be treated immediately.

Thyroid Surgery

Thyroid surgery is a procedure to remove all or part of the thyroid gland. The thyroid is a small, butterfly-shaped gland in the lower neck that regulates the hormones that manage metabolism. Thyroid surgery, also known as thyroidectomy, treats thyroid disorders such as hyperthyroidism (overactive thyroid), hypothyroidism (underactive thyroid), goiters (noncancerous thyroid inflammation), and thyroid cancer. It may also be used to remove thyroid nodules or cysts that have a risk of becoming cancerous.

Both hypothyroidism and goiters are caused by an autoimmune reaction where the body produces antibodies that attack the thyroid cells for unknown reasons. The thyroid reacts by releasing too little or too much T3 and T4 thyroid hormones, impairing thyroid function and causing irregular metabolism. Goiters develop from the autoimmune reaction causing continued antibody damage to the thyroid over time. Thyroid goiters are large, swollen lumps that can be felt near the base of the neck. Obstructive goiters can cause pain, coughing, and abnormal breathing. Hypothyroidism may also be caused by iodine deficiency, as iodine is needed to produce thyroid hormones.

The exact cause of thyroid cancer and thyroid nodules or cysts is unknown. While thyroid cancer and thyroid nodules or cysts can occur in individuals with thyroid disorders, they are not associated with a malfunctioning thyroid.

Physicians may prescribe thyroid surgery if blood tests reveal patients' thyroid stimulating hormones (TSA) are outside of the acceptable range, indicating a malfunctioning thyroid. Thyroid biopsies (tissue samples) and tests for thyroid-attacking antibodies are also criteria for surgery.

An ENT or general surgeon performs thyroid surgery. While a patient is placed under anesthesia, the surgeon makes an incision at the center of the neck and removes the thyroid gland. Two alternative methods of thyroid surgery are transoral (incision through the mouth) and endoscopic, where a surgeon operates a video camera for live footage to help guide the removal process.

Thyroid surgery requires minimal aftercare. Most patients recover quickly and resume normal activities within a few days of surgery. However, thyroid surgery patients must take daily synthetic thyroid medication (levothyroxine) for life to replace their removed thyroid.
