    Summary
    This summary is machine-generated.

    Nuclear segmentation in fine needle aspirate smears is significantly higher in toxic goitres (2.2%) than atoxic goitres (0.9%). This finding aids in differentiating thyroid conditions based on nuclear morphology.

    Area of Science:

    • Cytopathology
    • Endocrinology
    • Thyroid disease research

    Background:

    • Fine needle aspiration (FNA) is a key diagnostic tool for thyroid nodules.
    • Nuclear morphology in thyroid aspirates can indicate disease state.
    • Distinguishing between toxic and atoxic goitres is crucial for patient management.

    Purpose of the Study:

    • To investigate the presence and significance of nuclear segmentation in thyroid goitres.
    • To determine if nuclear segmentation differs between toxic and atoxic goitres.
    • To assess the diagnostic utility of nuclear segmentation in differentiating these conditions.

    Main Methods:

    • Analysis of fine needle aspirate smears from patients with toxic and atoxic goitres.
    • Utilizing a smear technique that flattens nuclei for enhanced visualization.

  • Quantifying the percentage of nuclei exhibiting segmentation.

    • Main Results:

    • Nuclear segmentation was observed in 2.2% of nuclei in toxic goitres.
    • Nuclear segmentation was observed in 0.9% of nuclei in atoxic goitres.
    • The difference in nuclear segmentation between toxic and atoxic goitres was statistically significant (p < 0.001).

    Conclusions:

    • Nuclear segmentation is a quantifiable feature in thyroid FNA smears.
    • Significantly higher nuclear segmentation is characteristic of toxic goitres compared to atoxic goitres.
    • This cytological finding may serve as a valuable marker for differentiating toxic from atoxic goitres.
