Summary
Forensic pathology can now better detect neck compression using postmortem serum free triiodothyronine (fT3) levels adjusted for thyroid weight. This Neck Compression Score (NCS) improves diagnostic accuracy, especially in cases with minimal external signs.
Area of Science:
- Forensic Pathology
- Biomarker Analysis
- Toxicology
Background:
- Neck compression diagnosis in forensic pathology is challenging, especially with minimal external signs.
- Postmortem serum thyroglobulin (Tg) has limited reliability as a biomarker for neck compression.
Purpose of the Study:
- To evaluate the diagnostic utility of postmortem serum free triiodothyronine (fT3) for neck compression.
- To determine if adjusting fT3 levels for thyroid weight improves diagnostic performance.
Main Methods:
- Retrospective analysis of 130 forensic autopsy cases (78 neck compression, 52 controls).
- Measurement of postmortem serum fT3 and Tg levels.
- Thyroid gland weight measurement and multivariable logistic regression analysis.
Main Results:
- Serum fT3 and Tg levels were significantly higher in the neck compression group.
- fT3 and thyroid weight were identified as independent predictors of neck compression.
- The developed Neck Compression Score (NCS) showed good diagnostic performance (AUC 0.811), outperforming fT3 alone.
Conclusions:
- Postmortem serum fT3 is a useful screening tool for neck compression.
- Adjusting fT3 for thyroid weight enhances diagnostic sensitivity.
- The NCS provides a quantitative adjunct for evaluating neck compression alongside macroscopic findings.

01:20Synthesis and Regulation of Thyroid Hormones
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 iodine is then...

01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:23The Thyroid Gland
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...

01:23Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
