Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

4.9K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Measures of Central Tendency

21.2K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

What is Central Tendency?

17.6K
Descriptive statistics describe or summarize relevant characteristics of a sample and aid in the analysis of data of interest. When analyzing large quantities of data and developing an inference, one needs to identify a value representative of the entire data set. Characteristics such as central tendency, extreme values, range of measurements, or the most repeated value can help better understand the data.
The central tendency is the most conventionally used data characteristic. It is a...

Trait Centrality01:21

Trait Centrality

198
Trait centrality refers to the degree to which a particular characteristic influences the overall impression of an individual. Some traits exert a disproportionately strong impact on perception, shaping how people interpret other attributes of a person. Solomon Asch first systematically studied this phenomenon in 1946.Asch’s Experiment on Trait CentralityAsch's seminal study demonstrated the centrality of certain traits through a controlled experiment. Participants were presented with a...

Summary
This summary is machine-generated.

Endoscopic thyroidectomy by bilateral areola approach (ETBAA) allows for feasible central compartment dissection (CND) in papillary thyroid cancer (PTC) patients. This minimally invasive technique yielded more lymph node retrieval than open thyroidectomy with comparable safety.

Area of Science:

  • Surgical Oncology
  • Minimally Invasive Surgery
  • Endocrinology

Background:

  • Endoscopic thyroidectomy by bilateral areola approach (ETBAA) may face challenges in central compartment lymph node dissection (CND) due to anatomical limitations.
  • A comparative analysis between ETBAA and open thyroidectomy approach (OTA) for CND is warranted.

Purpose of the Study:

  • To compare the efficacy and safety of ETBAA versus OTA for central compartment dissection in papillary thyroid cancer (PTC) patients.
  • To evaluate the technical feasibility of ETBAA for comprehensive CND.

Main Methods:

  • A comparative study involving 400 PTC patients undergoing CND from October 2013 to August 2017.
  • 200 patients underwent ETBAA using a 10-mm areolar incision and accessory ports for endoscopic visualization.
  • 200 patients underwent OTA for CND.

Main Results:

  • Significantly more lymph nodes were retrieved during ETBAA (mean 5.25) compared to OTA (mean 4.58) (P<0.05).
  • Metastatic rates were 18.6% for ETBAA and 12.1% for OTA, with no significant difference in resected side or surgical morbidity.
  • No recurrence or detectable serum thyroglobulin was observed in either group during follow-up.

Conclusions:

  • Central compartment dissection is feasible using the endoscopic thyroidectomy by bilateral areola approach.
  • ETBAA offers a viable minimally invasive alternative for CND in PTC management.
