Enlargement of the Plasma Membrane01:22

Enlargement of the Plasma Membrane

2.3K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

The Thyroid Gland01:23

The Thyroid Gland

6.9K
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...

Functions of Thyroid Hormones

5.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Protein Complex Assembly02:41

Protein Complex Assembly

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Cranial Bones: Superior and Posterior View

5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

7.4K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Summary
This summary is machine-generated.

Thyroid eye disease (TED) can present with superior rectus/levator complex enlargement, often leading to proptosis and eyelid abnormalities. Early diagnosis through imaging and antibody testing is crucial for timely management.

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Immunology

Background:

  • Thyroid eye disease (TED) is an autoimmune condition affecting the orbit.
  • Superior rectus/levator complex involvement is a less common initial presentation of TED.
  • Accurate diagnosis and characterization of TED presentations are essential for patient management.

Purpose of the Study:

  • To describe the demographic and clinical characteristics of patients with TED presenting with predominant superior rectus/levator complex involvement.
  • To identify key clinical features and imaging findings associated with this specific TED presentation.
  • To evaluate the diagnostic utility of orbital imaging and laboratory markers in these patients.

Main Methods:

  • Retrospective review of multi-institutional data.
  • Identification of TED patients with superior rectus/levator complex involvement.
  • Analysis of baseline and follow-up clinical data, including imaging and laboratory results.

Main Results:

  • Nineteen patients identified with enlarged levator/superior rectus complex on imaging.
  • All patients exhibited proptosis; 58% had vertical misalignment.
  • Elevated thyroid stimulating immunoglobulin (TSI) levels were noted in some patients.
  • Follow-up revealed potential enlargement of other extraocular muscles in some cases.

Conclusions:

  • Superior rectus/levator complex enlargement as an initial TED presentation may be under-recognized.
  • Orbital imaging and laboratory evaluations (e.g., TSI) support TED diagnosis.
  • Patients with suggestive findings may develop more typical TED features over time.
