What is ATA classification?

Definition. A numerical technical classification of all the systems and sub systems on an aircraft which is universally used in aircraft engineering and aircraft maintenance. It was developed by the former Air Transport Association (ATA) since renamed Airlines for America (A4A).

Is papillary thyroid cancer curable?

This cancer type grows slowly. Although papillary thyroid cancer often spreads to lymph nodes in the neck, the disease responds very well to treatment. Papillary thyroid cancer is highly curable and rarely fatal. Follicular: Follicular thyroid cancer accounts for up to 15% of thyroid cancer diagnoses.

What is the purpose of ATA?

Air transportation Association (ATA) published a numbering system to learn and understand the technical features of an Aircraft. ATA chapters make it easy to categorize technical information.

What is the ATA 100 system?

ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike.

Can stress cause thyroid nodules?

Stress alone will not cause a thyroid disorder, but it can make the condition worse. The impact of stress on the thyroid occurs by slowing your body’s metabolism. This is another way that stress and weight gain are linked.

What are the two types of MTC?

Medullary thyroid cancer (MTC). There are two types of MTC: sporadic and familial. Sporadic MTC occurs mostly in adults, does not occur in families, and usually affects only one lobe of the thyroid gland. Familial MTC can develop during early childhood, occurs in families, and can spread to other parts of the body.

What causes MTC?

In MTC, the flushing, diarrhea, and itching (pruritus) are all caused by elevated levels of calcitonin gene products (calcitonin or calcitonin gene-related peptide). By comparison, the flushing and diarrhea observed in carcinoid syndrome is caused by elevated levels of circulating serotonin.

Which is a high risk category for ATA?

In addition to the above, in 2015 ATA high-risk category includes patients with large-volume cervical metastases (≥3 cm) and follicular thyroid cancer with extensive vascular invasion. 2015, ATA guidelines can be summarized as follows: Clinical N0 or ≤5 pathologic N1 micrometastases (<0.2 cm in largest dimension)

When to use dynamic risk stratification in ATA?

In dynamic risk stratification, the patient’s risk of recurrence is reassessed during every followup based on primary therapy, response to therapy and the course of the disease for a minimum period of 2 years. At each follow-up visit, patients are classified as having one of the following clinical outcomes

Why is ATA risk stratification important for differentiated thyroid cancers?

This risk stratification in differentiated thyroid cancers is crucial to avoid overtreatment of low-risk and undertreatment of high-risk patients. It will also help to accurately identify those patients who are at risk of recurrence over the years and tailor their treatment plan accordingly.

Which is the best ATA calculator for thyroid disease?

The American Thyroid Association has posted these thyroid disease related calculators to provide assistance to practitioners for select practice areas concerning thyroid disease and thyroid cancer. It is recommended that these calculators be used in conjunction with respective ATA guidelines.
