The Parathyroid Glands00:59

The Parathyroid Glands

4.0K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

The Thyroid Gland01:23

The Thyroid Gland

6.2K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

380
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

1.8K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

5.4K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

3.5K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Summary
This summary is machine-generated.

Fine-needle aspiration (FNA) of neck masses, including thyroid nodules and lymph nodes, is effective. This biopsy technique is safe for anticoagulated patients and offers valuable diagnostic information with minimal complications.

Area of Science:

  • Diagnostic imaging and interventional procedures.
  • Head and neck oncology and endocrinology.

Background:

  • Neck masses frequently require biopsy for diagnosis, with thyroid nodules, parathyroids, and lymph nodes being common targets.
  • Fine-needle aspiration (FNA) is a primary method for evaluating these lesions.

Purpose of the Study:

  • To summarize the key aspects and diagnostic utility of fine-needle aspiration and core biopsy for neck masses.
  • To highlight procedural considerations and diagnostic enhancements for specific neck lesions.

Main Methods:

  • Review of fine-needle aspiration (FNA) and core biopsy techniques for neck masses.
  • Discussion of diagnostic yield related to the number of passes for thyroid nodules.
  • Consideration of specific assays (thyroglobulin, parathyroid hormone) for lymph node and parathyroid biopsies.

Main Results:

  • Diagnostic yield for thyroid nodule FNA plateaus after approximately 6 passes.
  • Thyroid FNA is feasible and safe in anticoagulated patients.
  • Additional assays improve diagnostic sensitivity for recurrent thyroid cancer and parathyroid evaluation.

Conclusions:

  • Neck biopsies, particularly FNA, are simple procedures with low complication rates.
  • Optimized techniques and adjunctive assays enhance the diagnostic value of neck biopsies for various lesions.
