Thyroid to salivary (TS) ratio is the most commonly used scintigraphic parameter for differentiating euthyroid and hyperthyroid cats. Studies to determine the normal TS ratio have been performed in small cat populations. In this study, the TS ratio was determined in 32 cats between 8 and 13 years of age. The study population was documented to be euthyroid based on normal initial and 6-week follow-up serum thyroid concentrations and normal T3 suppression tests. All images were obtained with a low-energy all-purpose collimator between 20 and 40 min after the injection of approximately 111 MBq (3.0 mCi) pertechnetate. Manual regions of interest (ROI) were made of the thyroid and salivary glands of the ventral image A 95% prediction interval based on the natural log of the TS ratio was computed to provide a normal range of 0.48-1.66. This range is similar to previous studies, but suggests a slightly higher upper limit than previously reported.

Introduction: Thyroid lesions are one of the most common diseases observed in clinical practice in the North India. These diseases have distinct cytological morphology and thus FNAC is done frequently. Here we report a case of adenomatoid goitre mimicking adenoid cystic carcinoma (ACC) of salivary gland on cytology.

Introduction: A growing amount of evidence points at lymph node yield (LNY) and lymph node ratio (LNR) as useful indicators in the prognostic evaluation of patients affected by head and neck squamous cell carcinoma (HNSCC) who require neck dissection. The aim of this study was to assess the importance of LNY and LNR in the prognostic evaluation of head and neck cancer patients.
Materials And Methods: Included studies were those examining LNY and/or LNR in head and neck cancer patients.
Introduction: Thyroid and salivary gland cytopathology frequently present diagnostic challenges due to complex presentations, overlapping features between benign and malignant conditions, particularly with grey-zone entities and rare pathologies. To address these issues, the 45th European Congress of Cytology (ECC) held a slide seminar focused on challenging cases. This article reviews key findings from the six cases discussed, emphasizing the importance of a comprehensive diagnostic approach.

Autoimmune thyroid disorders (AITD) are the most common autoimmune human disorders as thyroid gland is a main target for autoimmunity. The association between rheumatologic and thyroid disorders has long been known, the most common being the association with rheumatoid arthritis. Our study was conducted to screen for the presence of symptoms, signs and immune markers suggesting presence of Sjogren's syndrome among patients with autoimmune thyroid disorders.

Objectives: To evaluate the impact of thyroid diseases (TD) on the comorbidities incidence and immune system of patients with primary Sjögren's syndrome (pSS).
Methods: A total of 329 patients diagnosed with pSS who were admitted between January 2018 and September 2023 were evaluated. The patients were divided into two groups: those with and without TD.
