“…[24] However, USG can not differentiate the lesions which are not surrounded by normal tissue. [24,25] Despite a significant increase in earlier stage diagnosis of thyroid cancer there is no decrease in mortality due to this disease. [27] Studies have suggested that there are more than 5% prevalence of thyroid nodules; whereas, investigators have shown more than 50 % of randomly selected population showed nodules in thyroid gland during ultrasonography.…”

Background: Thyroid diseases are, debatably, among the commonest endocrine disorders worldwide. According to a projection from various studies on thyroid disease including thyroid nodules, it has been estimated that about 42 million people in India suffer from thyroid diseases. The ultrasonography is a non-invasive sensitive diagnostic in assessing thyroid nodule size and number. This study aimed to determine the ultrasound findings of thyroid nodules in patients and correlate it with clinical records. Methods: This was a cross-sectional study conducted at teerthanker Mahavir medical college and research centre. In these patients, high frequency 7.5-10.0 MHz probe was used for Ultrasound examination of a thyroid nodule. It includes diameter, echogenicity (Hyper, Hypo, Iso and An Echo), composition (Cystic, Solid, Mixed), microcalcifications (Presence and Absence), Borders (Irregular and Regular) and Halo (Presence and Absence). From Lew et al. guidelines ultrasound of nodule margins, suggestive of malignancy guidelines was adopted. A fine needle aspiration (FNA) biopsy was recommended to the referring physician is required. Results: Benign and malignant lesions were recorded in 88.9% and 11.1% patients respectively. On the other hand, histopathological findings revealed that 90.9% and 9.1% as benign and malignant correspondingly. In the present study, sensitivity, specificity and positive predictive values were 91%, 8.5% and 50% respectively. Whereas, the negative predictive value was 47%. Conclusion: Findings of the current study suggest that radiological evidences are reliable enough for the diagnosis of the benign and malignant thyroid tumours. However, studies on larger populations are warranted to establish guideline for the radiological diagnosis of thyroid tumours.

“…REVISIÓN DE LA BIBLIOGRAFÍA Con el fin de obtener los objetivos fijados, realizamos una revisión los protocolos y téc-nicas recomendados por las principales sociedades científicas orientados al estudio de las glándulas tiroides y paratiroides, principalmente para la correlación con las aplicaciones disponibles en nuestro centro, para poder evaluar las diferentes pruebas diagnós-ticas, las indicaciones y los criterios de inclusión [11][12][13].…”

“…The major limitation of ultrasound in thyroid imaging is that it cannot determine thyroid function, i.e. whether the thyroid gland is underactive, overactive or normal in function; for which a blood test or radioactive isotope uptake test is generally required [4], [5]. However, when Doppler US is used, increased gland vascularity may often indicate hyperthyroidism.…”

Several interactions exist between thyroid and kidney function in many disorders. Many publications explored the relationship between thyroid diseases (TD) and chronic kidney diseases (CKD). However, the morphological thyroid changes in patients with CKD or End Stage Kidney Disease (ESKD) were not fully explored. The aim of this study is to explore the morphological and the functional abnormalities of the thyroid gland among ESKD patients as detected by Doppler ultrasound. Patients and methods:All of the 92 ESKD patients at our center were consented and included in the study.Demographic and clinical data and biochemical and hormonal profiles were recorded. Every patient received a dedicated ultrasound scan of the thyroid gland. GE ultrasound system with Doppler capabilities and high frequency transducer was used. Grey scale imaging and Doppler ultrasound were used to image the thyroid gland for every patient. Taking the thyroid morphology detected by ultrasound and the thyroid function as the dependent variables, all other parameters of age, sex, BMI, occupation, residence, duration of time on dialysis and other comorbilities were taken as independent variables and their relationship to the dependent variables was further studied using appropriate statistical tests.Results: Thyroid nodule(s) presence was found to be the most prevalent thyroid morphology detected on ultrasound scanning. Fifty three patients (57.6%) were found to have ultrasound detected nodule(s). The nodule presence was correlated to different independent variables and was found to significantly correlate with age only. The thyroid function as reflected by the level of thyroid hormones was also studied for correlation with the independent variables. No correlation was found between the thyroid function and the presence of nodules. Conclusion and recommendation:Ultrasound detected nodules are very common in ESKD patients. The presence of nodule significantly correlates with patient age denoting its degenerative nature. Ultrasound screening of the thyroid in ESKD patients may be cost effective. However, we recommend a larger multicenter study for better results.
