Clinico-cytomorphological features and thyroid function tests of different thyroid lesions – A hospital-based cross-sectional study

Background: Thyroid gland is an endocrine organ. The non-neoplastic and neoplastic conditions affecting the gland can manifest as the swelling of the gland with thyroid dysfunction. Based on cytology, the diseases can be categorized into non-neoplastic, benign neoplastic, and malignant neoplastic conditions and according to hormone status, the lesions of thyroid can be categorized in hypothyroid, euthyroid, or hyperthyroid condition. Aims and Objectives: Our study was done to find out the various cytomorphological spectrum of thyroid diseases and to record their common clinical presentation along with hormonal status in a tertiary care hospital in Northern Odisha. Materials and Methods: A total of 220 cases of thyroid disorder were taken for analysis over a period of 2 years. Patients demographic data, brief clinical features, finding on FNAC (cytomorphology), and thyroid function status were analyzed with appropriate statistical method. Results: The predominant age group affected was 21–40 years and total female to male patient ratio was 5.5:1. Most common presentations were heat intolerance (22.27%), cold intolerance (28.63%), and tachycardia (27.72%) apart from thyroid enlargement. Most common non-neoplastic lesion were multinodular and colloid goiter constituting 38.18% of total cases and most common neoplastic lesion was papillary carcinoma constituting 14.55% of total cases. Thyroid function test showed predominantly euthyroid states for all conditions. Conclusion: As the rest part of India, this part of Odisha also showed that thyroid disorders are more common in females and the most affected age group is 21–40 years. Multinodular and colloid goiter are the most common thyroid lesions. Most of the cases present with euthyroid state.

Goitre plongeant: Particularités cliniques et thérapeutiques / Sub-sternal goitre: Clinical and therapeutic features

Etudier les caractéristiques cliniques, radiologiques et thérapeutiques des goitres plongeants et établir un arbre décisionnel de prise en charge Méthodes: Nous rapportons une étude rétrospective portant sur 67 cas de goitre plongeant colligés sur une période de 27 ans entre 1990 et 2016. Résultats: L'âge moyen des patients était de 53 ± 15,1 ans et le sex-ratio de 0,24. La tuméfaction basicervicale antérieure était le motif de consultation le plus fréquent, rapportée dans 82% des cas associée à des signes de compression dans 31% des cas. Une paralysie récurrentielle unilatérale a été objectivée dans quatre cas. Une radiographie de thorax a montré une opacité médiastinale dans 75% des cas et une déviation trachéale dans 85% des cas. Un scanner cervico-thoracique pratiquée dans 73% des cas a confirmé le diagnostic en objectivant cinq prolongements dépassant la crosse de l'aorte. Le traitement chirurgical était mené par voie cervicale dans 99% des patients et une sternotomie a été réalisée devant l'échec d'extraction par cervicotomie. Une paralysie récurrentielle postopératoire a été observée dans un cas et l'hypoparathyroïdie définitive a été rapportée chez six malades avec un recul moyen de trois ans. Conclusion: Les goitres plongeants sont devenus rares en Tunisie du fait de la prise en charge plus précoce des nodules thyroïdiens. Le scanner cervico-thoracique représente le gold standard pour l'étude et la confirmation du diagnostic du goitre plongeant ainsi que pour l'attitude thérapeutique. L'indication chirurgicale est toujours impérative devant le risque vital qu'il pose.

El tratamiento paciente específico del hipertiroidismo con radioyodo: una oportunidad a la mejora / Radioiodine treatment of hyperthyroidism with patient-specific techniques: an improvement opportunity

Introducción: La aplicación de actividades fijas en el tratamiento del hipertiroidismo con I131 (yoduro de sodio, conocido también como radioyodo), es el método más usado en nuestro país, a pesar de la individualidad morfo-funcional que caracteriza esta afección. Sin embargo, no existe aún, un consenso internacional sobre la dosis más conveniente para cada caso, y por ende, los resultados no siempre son los deseados. Objetivo: Evaluar la aplicabilidad de varios métodos de cálculo de dosis paciente-específica para el tratamiento de hipertiroidismo con yoduro de sodio. Métodos: Se realizó un análisis de los resultados de varios métodos de cálculo de dosis recomendados internacionalmente a partir de la actividad fija prescrita en 10 pacientes, con el empleo de tecnologías y herramientas ya desarrolladas y disponibles en el país. Se evaluó la variabilidad inter-especialista y su impacto en la dosis planificada para el tratamiento. Resultados: El uso de la información incompleta de la biodistribución y farmacocinética del paciente produjo diferencias entre -42 por ciento y 37 por ciento de las dosis para el mismo paciente. El resultado de la comparación del método de cálculo recomendado por la Sociedad Europea de Medicina Nuclear, manejando la masa por gammagrafía-2D / 3D y por ultrasonido, arrojó diferencias no significativas entre sí. La variabilidad inter-especialista de las actividades prescrita mostró diferencias significativas, que arrojan sobre el mismo paciente, discrepancias entre 44Gy y 243Gy de las dosis terapéuticas a recibir, situación que puede comprometer el éxito del tratamiento y producir efectos secundarios no deseados. Conclusiones: Las técnicas dosimétricas paciente-específicas se pueden implementar satisfactoriamente en nuestro país. Las diferencias numéricas encontradas, especialmente la variabilidad inter-especialista, demuestran la no estandarización terapéutica, lo que apoya el uso de la farmacocinética paciente-específica pre terapéutica y la masa por gammagrafía-3D para planificar el tratamiento siempre que sean posible(AU)

Introduction: Despite of its typical morpho-functional individuality, fixed activities remain as the most used method in Cuba for hyperthyroidism treatment with I (sodium iodide, also known as radioiodine). However, there is not yet an international consensus on the most convenient doses for each case, so, the results are not always the desired ones. Objective: To evaluate the applicability of various patient-specific dose calculation methods for the treatment of hyperthyroidism with sodium iodide. Methods: It was carried out an analysis in 10 patients of the results of some methods for dose calculation from the prescribed fixed activity recommended internationally, with the use of technologies and tools already developed and available in the country. The inter-specialist variability and its impact in the planned dose for the treatment were assessed. Results: The use of uncompleted biodistribution and pharmacokinetics information of the patient showed differences between -42 percent and 37 percent in the doses for the same patient. The outcome of the comparison of the calculation method recommended by the European Society of Nuclear Medicine managing the mass by 3D/2D gammagraphy and ultrasound, presented no significant discrepancies among them. The inter-specialist variability of prescribed activity was statistically significant, and it can produce in the same patient differences between 44Gy and 243Gy of the therapeutic doses, which could affect the treatment success and lead to unnecessary side effects. Conclusions: The patient´s personalized calculation methods can be satisfactorily applied in Cuba. The numeric differences found, especially inter-specialist variability, show the lack of therapeutic standardization, which supports the use of pre-therapeutic patient-specific pharmacokinetics and the mass by 3D-gammagraphy to plan the treatment when possible(AU)

Large posterior mediastinal goiter post total cervical thyroidectomy: a case report

Thoracotomy approach is indicated for a complete and safe posterior mediastinal goitre removal. A 68 years old male was hospitalized due to a right mediastinal mass found in a chest X-ray and confirmed by computed tomography. The patient had undergone total cervical thyroidectomy thirty years ago. A computed tomography (CT) guided percutaneous needle biopsy of the mass revealed thyroid tissue. Subsequently, the mass was completely resected through a right posterolateral thoracotomy. The histopathology confirmed a large mediastinal goitre with no signs of malignancy. The patient had an uncomplicated recovery. We present a relatively rare case of a successful resection of a posterior mediastinal goitre, occurring thirty years post-total cervical thyroidectomy. We advocate lateral thoracotomy to achieve a broad operative field and enhance surgical safety.

Accuracy of fine needle aspiration cytology and thyroid imaging reporting and data system to predict the nature of nodular goiter and its comparison with postoperative histology

Background: Aim of the study was to find accuracy of pre-operative fine needle aspiration cytology (FNAC) and thyroid imaging reporting and data system (TIRADS) in predicting the nature of nodular goitre and confirming it with post-operative biopsy. Objective of the study was to assess the sensitivity and specificity of FNAC compared with post-operative biopsy and to assess the sensitivity and specificity of TIRADS compared with post-operative biopsy.Methods: This retrospective study was carried out at tertiary hospital, King George Hospital, Visakhapatnam over a period of 1 year from march 2018 to march 2019. Sensitivity and specificity are calculated based on formulae.Results: Sample size calculated with 90% confidence interval for population of vizag is 96, a sample of 100 patients were taken in this study. Of the 100 cases, 16 had thyroid carcinoma. 15 of them were papillary carcinoma and 1 follicular carcinoma. 8 cases matched with cytology report after post op biopsy and 8 we mismatched with cytology report after post op biopsy. The incidence of malignancy in clinically and cytologically benign goitre is 8.69. In our study sensitivity of FNAC is 50%, specificity is 100% and accuracy of test is 92% and TIRADS has a sensitivity of 100% and specificity of 72.62% and an accuracy of 77%.Conclusions: The current study has showed the disparity we see in thyroid neoplasms in FNAC test and TIRADS, which were proved to be different diagnosis in clinical and histopathology, so even if cytology is benign, we can’t rule out malignancy. FNAC and TIRADS combined have more sensitivity and specificity than individual tests.

A comparative study of postoperative hypocalcaemia following total thyroidectomy in patients with Hashimoto’s thyroiditis and multinodular goitre in a rural tertiary care hospital

Background: Recurrent laryngeal nerve injury, hypothyroidism and hypocalcaemia have long been recognized as the three main sequalae of thyroidectomy. Persistent hypocalcaemia may cause intracranial lesions and cardiac arrhythmias. As the definitive diagnosis of Hashimoto’s thyroiditis was not always possible with clinical and cytological parameters when antibody testing was not done, surgery was planned with the diagnosis of multinodular goitre. This study was conducted to find out the incidence of post-operative hypocalcaemia following total thyroidectomy by skilled surgeons in patients with multinodular goitre and Hashimoto’s thyroiditis.Methods: This was a cross-sectional study to compare the incidence of hypocalcaemia in patients with biopsy-proven Hashimoto’s thyroiditis and multinodular goitre. After obtaining approval from the institutional review board and ethics committee, data was collected serially, from the surgical records of 123 patients who underwent total thyroidectomy in this tertiary care centre, during the past two years.Results: The incidence of post-operative hypocalcaemia (71.1%) in patients undergoing total thyroidectomy with Hashimoto’s thyroiditis was significantly higher than in patients with multinodular goitre (56.4%). Of the 45 patients who had a biopsy report of Hashimoto’s thyroiditis, 8 (17.8 %) developed permanent hypocalcaemia while only 8 (10.3%) of the 78 patients with histopathological diagnosis of multinodular goitre developed persistent hypocalcaemia needing supplementation following total thyroidectomy in this rural tertiary care hospital.Conclusions: The significant risk of post-operative hypocalcaemia should be kept in mind before opting for total thyroidectomy for benign lesions of the thyroid and pre-operative antibody studies must be done to diagnose Hashimoto’s thyroiditis.

Incidence of thyroid pathologies requiring thyroid surgeries in a tertiary care hospital

Background: Diseases of the thyroid gland are one of the most common endocrine disorders in India and the world, many of these diseases require surgery for their treatment. The incidence of thyroid diseases differs from one geographical area to another. This study was aimed at finding out the thyroid pathologies for which thyroid surgeries were performed in D. Y. Patil Hospital, Nerul, Navi Mumbai.Methods: It is a retrospective analysis of all the patients who have undergone thyroid surgeries (lobectomy, hemithyroidectomy, subtotal or near total thyroidectomy or total thyroidectomy) in D. Y. Patil hospital, Nerul, Navi Mumbai from 1st January 2018 to 31st December 2019 (2 years duration).Results: Most common pathology for which thyroidectomy was performed was colloid goitre (41.33%). Benign diseases of the thyroid was much more common (76%) than malignant diseases (24%). Most common malignancy was papillary carcinoma thyroid. Thyroid surgeries were most commonly performed on women in their 5th decade of life.Conclusions: Colloid goitre was the most common pathology for which thyroid surgeries were performed and females in their 5th decade of life were the most common patients undergoing thyroidectomy.

A study of correlation of pre-operative fine needle aspiration cytology and ultrasonography with post-operative histopathology in thyroid swellings

Background:Diseases of the thyroid gland can be due to inflammatory and neoplastic causes. Many diagnostic tests like ultrasound, thyroid nuclear scan and fine needle aspiration cytology (FNAC) are available for their evaluation. Histopathologically, they can be adenomas, colloid nodules, cysts, infectious nodules, lymphocytic or granulomatous nodules, congenital abnormalities or hyperplasia, or various types of malignancy. It is therefore crucial to have a clear diagnostic approach to ensure patients are managed appropriately and are not over or under-treated. Present study was done to evaluate FNAC and ultrasonography (USG) as a diagnostic method in thyroid swellings and to plan surgery accordingly.Methods: A prospective observational study was conducted among 60 adult patients undergoing thyroid surgery at Victoria and Bowring and Lady Curzon Hospital. They were investigated with FNAC and USG of thyroid, and were subjected to surgery and subsequent histopathological examination. The histopathological examination reports were correlated with the findings of FNAC and USG in order to evaluate their findings by statistical methods.Results:The sensitivity and specificity of FNAC was 87.5% and 98% respectively. All malignant lesions on FNAC were confirmed by histopathology indicating its excellence. Therefore FNAC helps in planning the correct management and avoids second surgery. And the sensitivity and specificity of USG was 75% and 86% respectively. Therefore combination of both FNAC and ultrasonography will improve the diagnostic accuracy to higher level and helps in better management. Conclusions:FNAC has high sensitivity and specificity, so it is closest to ideal test. However, a combination of both FNAC and ultrasound will give desirable results and so that we can avoid mismanagement.

A study on risk factors for malignancy in solitary thyroid nodules at a tertiary care hospital

Background: Thyroid nodules are a common entity encountered in clinical practice and the prevalence by palpation is only 3-7%, but on ultrasonographic evaluation it is 20-76% with wide variability. Accurate prediction of malignancy with minimal diagnostic modalities and assessing the risk factors in malignancy may help in reducing extensive procedures. The objective of the study is to assess the risk factors associated with development of malignancy in solitary thyroid nodules and to find out the percentage of malignancy among the cases of solitary nodules.Methods: A three year prospective study was conducted at ACSR medical college and all cases diagnosed as solitary thyroid nodules were enrolled and institutional ethical approval was obtained. Socio demographic data, clinical history and ultrasonogram findings were collected and entered in a separate data sheet for analysis. Fine needle aspiration cytology, histopathological examination was done and reported findings were noted. Statistical analysis was done in SPPS version 20 and ‘p’ value <0.05 was considered significant.Results: 128 cases of solitary thyroid nodules (STN) with 41 male and 87 female cases and F:M ratio of 2.13:1 with mean age of 46.6±10.8 years was enrolled. 43.75% were euthyroid, 47.66% were hypothyroid and 8.59% were hyperthyroid on hormonal evaluation. Micro calcification was observed in 50.78%, increased vascularity in 38.28% and irregular margins in 34.38% of cases. Colloid goitre was predominant observation on fine needle aspiration cytology (40.6%) and follicular adenoma (32%) on histopathology.Conclusions: Features of micro calcification, solid echogenicity, and associated lymphadenopathy are associated features with increased risk of malignancy among STN.

Assessment of goitre among primary school children in district Chamba, Himachal Pradesh, India

Background: Goiter is one of the most visible manifestations of iodine deficiency disorders (IDD) that is caused due to overstimulation of thyroid as an adaptation to Iodine deficiency. IDD is among the major public health threats and important micronutrient deficiencies in developing countries.Methods: This cross-sectional study was conducted among 6-12 years school children in district Chamba of Himachal Pradesh from February to June 2019. The sample size of 336 was calculated and a total of 504 children from government schools were enrolled in the study. The assessment of goitre was done clinically by inspection and palpation of thyroid gland.Results: In this study, 504 school aged children of 6-12 yrs from district Chamba with mean age of 9±1.86 years were included. The prevalence of total goitre rate was 16% with mean age of 8.75±1.37 years. The highest prevalence (%) was observed in age of 10 years (28.4%) followed by 8 years and 9 years (25.9 % and 23.5% respectively).Conclusions: This study showed mild goitre prevalence in school aged children of 6-12 years in district Chamba of Himachal Pradesh. There is dire need of periodic survey to assess the magnitude of IDD in future.

Giant retrosternal goiter masquerading as, right posterior mediastinal mass: a rare case report

Complete mediastinal plunging thyroid gland is a rare entity, accounting for 1% of all mediastinal tumours, particularly posterior mediastinal tumour much more rare. We would like to present, a 30-year-old lady presented to ENT department with neck swelling and its further investigation shown to be giant posterior mediastinal mass. Thyroid function tests were normal. CT scans of the neck and chest revealed a large right mediastinal mass compressing the trachea from the right side and extending to the superior part of the posterior mediastinum with enlarged right thyroid gland in the cervical position. Midline extended sternotomy was done for complete surgical excision of the mass along with right hemi thyroidectomy. It was well circumscribed, capsulated, multinodular firm inconsistency, and vascular. Histopathology revealed thyroid tissue negative for malignancy. Giant plunging thyroid in the mediastinum is very rare. It should be differentiated from other mediastinal mass. The plunging goiter in posterior mediastinum is surgically challenging. Transsternal surgical removal is the treatment of choice in such cases.

Resultados a corto plazo del tratamiento con 131I en el bocio multinodular: valor adicional de la estimulación previa con rhTSH / Short-term results of treatment with 131I in multinodular goiter: additional value of previus stimulation with Recombinant human thyrotropin

OBJETIVO: El yodo radiactivo (131I) es una opción terapeútica segura y eficaz cuando se utiliza solo o con la estimulación previa de TSH recombinante humana (rhTSH) en el tratamiento del bocio multinodular (BMN). En espera de ensayos clínicos que determinen la dosis óptima, demuestren seguridad y confirmen la eficacia, diferentes protocolos se utilizan para aplicar la dosis de 131I. Analizamos la respuesta al tratamiento con una dosis calculada por protocolo mixto (dosis fijas y cálculo por porcentaje de captación) en pacientes con BMN toxico y no toxico en nuestro hospital, en el periodo 2010-2013. MATERIALES Y MÉTODOS: Estudio prospectivo en pacientes con BMN no quirúrgico (BMNNQ) que requerían reducción del volumen glandular y/o tratamiento del hipertiroidismo. Se evaluaron 134 pacientes, 14 cumplieron con los criterios de inclusión (13mujeres) de edad media 71.08 años. Un grupo con BMN toxico, otro grupo con BMN no toxico, un tercer grupo con BMN no toxico estimulado con 0,1 mg de rhTSH previo a la dosis. Se evaluó, función tiroidea, captación tiroidea de 99ᵐTc, volumen tiroideo y síntomas compresivos. Se siguió a los pacientes durante 12 meses. RESULTADOS: Se aplicaron dosis entre 15 y 30 mCi de 131I. Remitió el hipertiroidismo en 6 de 7 pacientes. Hubo una reducción del volumen glandular (p<0.01).Los pacientes con estímulo de 0,1 mg rhTSH, aumentaron el porcentaje de captación de 99ᵐTc a las 24 h en un 32.43±10.61 permitiendo aplicar menor dosis de 131I. La tasa de aparición de hipotiroidismo fue de 7.41 por cada 100 pacientes.mes, mayor en pacientes con BMN toxico tratados con dosis bajas (p-=0.03). Hubo una mejoría subjetiva de la clínica compresiva en todos los pacientes. No hubo eventos adversos. CONCLUSIONES: Una dosis de 131I calculada por protocolo mixto es efectiva y segura para la reducción del volumen glandular y control del hipertiroidismo asociado. La estimulación con rhTSH logra el mismo efecto con una menor dosis administrada.

OBJECTIVE: Radioactive iodine (131I) is a safe and effective therapeutic option when used alone or with prior stimulation of recombinant human Thyrotropin (rhTSH) in the treatment of multinodular goiter (MNG). In absence of clinical trials that determine the optimal dose, demonstrate safety and confirm efficacy, different protocols are used to apply the dose of 131I. We analyze the response to treatment with a dose calculated by mixed protocol (fixed doses and calculation by percentage of uptake) in patients with toxic and non-toxic MNG in our hospital, in the period 2010-2013. MATERIALS AND METHODS: Prospective study in patients with non-surgical MNG that required glandular volume reduction and / or treatment of hyperthyroidism. 134 patients were evaluated, 14 met the inclusion criteria (13 women) of average age 71.08 years. One group with toxic MNG, another group with non-toxic MNG and a third with non-toxic multinodular goiter stimulated with 0.1 mg of rhTSH prior to the dose. Patients were followed for 12 months. Upon following, we assessed Thyroid function, 99ᵐTc thyroid uptake, thyroid volume and compressive symptoms. RESULTS: Doses between 15 and 30 mCi of 131I were applied. We observed hyperthyroidism remission in 6 of 7 patients. There was a reduction in glandular volume (p <0.01) considering all patients. Patients with a stimulus of 0.1 mg rhTSH, increased the percentage of uptake of 99ᵐTc at 24 h by 32.43 ± 10.61, allowing a lower dose of 131I to be applied. The rate of onset of hypothyroidism was 7.41 per 100 patients-month, and was higher in patients with toxic MNG treated with low doses (p = 0.03). There was a subjective improvement of the compression clinic in all patients. No adverse events were observed. CONCLUSIONS: A dose of 131I calculated by a mixed protocol is effective and safe for achieving glandular volume reduction and associated hyperthyroidism control. Stimulation with rhTSH produces the same effect with a lower administered dose.

A seven year experience in patients undergoing total thyroidectomy for benign diseases in a single unit of tertiary care centre: a retrospective case study

Background: Thyroidectomy is a common surgical procedure performed worldwide by surgeons with varied training. It is the experience and the skills by which a surgeon performs, the indication of surgery and the extent of surgery which determines the outcome and the complication rates.Method: This study is a retrospective study performed from January 2012 to December 2018 when a total of 170 patients underwent total thyroidectomy via kocher’s incision for benign diseases with clinically in hypothyroid state at Safdarjung Hospital, New Delhi in a single unit of a tertiary care hospital.Results: The male: female ratio was 1:7.09 with average age of patients being 40years. The overall complication rate was 18.82% (32 patients). Postoperative transient hypocalcaemia being the most common complication. There was no case of permanent hypocalcaemia. There was no injury to any nerve (recurrent or superior laryngeal). Transient recurrent laryngeal paresis was noted in 4(2.35%) which resolved with conservative management. Complications like wound infection, sympathetic chain injury were not noted. The characteristic feature of this study was five cases of giant secondary retrosternal goitre which had average weight of greater than 500 grams which were operated using kocher’s incision. The average weight of other 165 patients was 70grams +/- 12 grams. There were no major post-operative complications except for post-operative recurrent laryngeal nerve paresis and seroma formation which was evacuated after 3 weeks of surgery.Conclusion: Hence, from this it is concluded that it is the surgical experience and skills of the surgeon which make total thyroidectomy a safe procedure providing permanent cure with a low post-operative morbidity risk even with large sized retrosternal thyroid glands which can be operated via neck incision.

Accuracy of FNAC for Diagnosis of Malignancy in Long Standing Multinodular Goiter and Histopathological Correlation

FNAC is widely accepted as the most accurate, sensitive,specific and cost affective diagnostic procedure in theassessment of thyroid nodules and helps to select people preoperative for surgery. The purpose of this study was toevaluate the accuracy of FNAC for diagnosis of malignancy inlong standing multinodular goiter and histopathological corelation. I evaluated the cytological and histological results of105 patients, who were underwent pre-operative FNAC andsubsequent surgery followed by post-operative histopathology.The cytological diagnosis was classified as- benign, suspiciousand malignant. The definitive cytological study showed benignlesion 92, suspicious 2 and malignant 11 among 105 patients.Post-operative histopathology study showed malignant lesion 9and 96 were benign, among the malignant lesion- 4 werefollicular variant of p. carcinoma and 4 were direct papillarycarcinoma. Benign lesions were distributed as 94 multinodulargoiter and 2 follicular adenoma. In FNAC- eleven patients werefound to be malignant but on post-operative histopathologyexamination confirmed 8 of them as malignant and 3 of themwere benign, 2 follicular adenoma and 1 multinodular goiter. 94patients were found to be benign in FNAC but post-operativehistopathology examination confirmed 93 as multinodular goiterand 1 papillary carcinoma. So total number of malignancyfound in post-operative histology is (8+1)= 9. Rest of them 96were benign. So there is discrepancy between 2 cases. So mystudy revealed a cytological and histological discrepancy in 2patient out of 105 patients due to either diagnostic or samplingerror.

Assessment of the Magnitude of Goiter in the Age Group of 6-12 Years in district Bandipura of Kashmir Division

Introduction: Iodine deficiency disorders (IDD) has beenrecognized as a public health problem in India Enlargementof thyroid gland is the common manifestation of the IDDand goiter prevalence survey is used as diagnostic tool foridentifying areas of IDD. Failure to undertake early detectionand intervention measure results in secondary disablingconditions. Aim: In the present study we have estimated theprevalence of goiter in the age group of 6-12 years in districtBandipura of Jammu and Kashmir state, India and haveassessed type of salt consumed by the population.Material and Methods: This was a Cross-sectional studyconducted in Bandipura district of J and K state and the studywas conducted between July 2018 to October 2018. Samplingmethod was Gender stratified cluster sampling technique andthe sample size was based on a goiter prevalence of 30% and95% confidence interval. 30 clusters were selected and eachcluster included 90 children. Data was entered in Microsoftexcel and then analyzed using appropriate statistical software.Data was interpreted using percentages, means and SD.Results: The prevalence of grade 1 and grade 2 goitre inmales was 35.6% and 15.1% respectively whereas it was30.8% and 15.1% in females and the prevalence was morein males to the extent of 52.08% and in girls it was 49.23%.Goitre was found to be highest (51.7%) in subjects 12 yearsof age and lowest (40.6%) in subjects aged 7 years of age.There was a significantly higher goitre prevalence in childrenwho consumed crystalline/non-iodised salt than in childrenconsuming iodised salt. The TGR was 61.4% and 46.9% inchildren consuming non-iodised and iodised salt respectivelyConclusion: We conclude our study with the finding thatpopulation of Bandipura district in the north Kashmir isseverely iodine deficient. We recommended a major thrustin the implementation of NIDDCP in the said district withregular and continuous monitoring of iodine status.

Correlations of water iodine concentration to earlier goitre frequency in Sweden-an iodine sufficient country with long-term iodination of table salt

BACKGROUND@#Before iodination of Swedish table salt in 1936, iodine deficiency resulting in goitre and hypothyroidism was common. Sweden has become iodine sufficient, as shown in a national survey in 2007, proving its iodination fortification programme effective for the general population. The objective of this study was to collect drinking water from water treatment plants nationally and test if water iodine concentration (WIC) correlated to urinary iodine concentration (UIC) of school-aged children in a national survey 2007 to former goitre frequency in 1929 and to thyroid volume data in 2007.@*METHODS@#In 2012, 166 treatment plants, located in 57% (166 of 290) of all Swedish municipalities, were asked to collect drinking water samples of approximately 10 ml. In 2007, tap water samples of the same volume were collected from 30 randomly selected schools for the national survey. Analysis of WIC was done in both treatment plants in 2012 (n = 166) and tap water in 2007 (n = 30). The correlation of WIC to the children's UIC and thyroid volume after iodination was tested based on data from the national survey in 2007. The association of WIC to former goitre frequency was tested based on pre-iodination data, derived from a map of goitre frequency drawn in 1929.@*RESULTS@#The median WIC from water treatment plants was 4.0 μg/L (range 0-27 μg/L). WIC was similar in coastal and inland areas, for both ground and surface water. WIC correlated with historical goitre areas and was lower in the goitre areas than in non-goitre areas (p < 0.001). WIC in the same municipalities as the schools correlated with the UIC of children (p < 0.01), but not with their thyroid volume.@*CONCLUSIONS@#WIC still contributes to iodine nutrition in Sweden, but iodination overrides the goitre effect.

Living in Rural Areas of Peninsular Malaysia: Risk Factor for Goitre

@#Introduction: Thyroid disorders are among common medical conditions encountered in clinical practice. However, the disease burden among Malaysian population has not been established. This study was aimed to determine the prevalence of goitre and its associated factors among adult population in Peninsular Malaysia. Materials and Methods: A cross-sectional study was performed in 5 pre-assigned regions in Peninsular Malaysia. Participants’ sociodemographic profile and medical history were recorded. Physical examinations were done looking for abnormalities of the thyroid gland and signs of thyroid dysfunctions. The diagnosis of goitre was made by palpation and corroborated by the repeat examination by another investigator. The World Health Organization (WHO) goitre grading system was used. Fifteen millilitre of blood were withdrawn and analysed at a central laboratory. Results: Among 2190 respondents, the prevalence of goitre was 9.3%. Goitre was associated with positive anti-thyroperoxidase and anti-thyroglobulin antibodies. Females were at higher risk of goitre (adjusted OR = 2.4; 95% CI 1.6–3.5; p<0.001). The other risk factors of goitre were Indian ethnicity (adjusted OR=2.0; 95%CI 1.2–3.3; p=0.006), positive anti-thyroperoxidase (adjusted OR=1.8; 95% CI 1.1-3.1; p=0.024) and living in rural area (adjusted OR = 1.7; 95% CI 1.2–2.5; p=0.002). These areas had been shown to suffer from some degree of iodine insufficiency in the past. Conclusions: The prevalence of goitre in Peninsular Malaysia was comparable with other studies. The main predictors of thyroid disorders are female gender and thyroid antibodies. Living in rural areas was associated with goitre.

Histopathological analysis of thyroid lesions: an institutional experience

Background: Diseases of thyroid are one of the most common endocrine disorders affecting general population which range from non-neoplastic to neoplastic lesions. The incidence and pattern of thyroid lesions depend on various factors which include sex, age, ethnic and geographical patterns. Majority of thyroid lesions are non-neoplastic only <5% are malignant. The aim of the present study was to determine the frequency and histomorphological pattern of thyroidectomy specimens and their relationship with age and sex of the patient.Methods: This retrospective study was conducted in the department of pathology, Govt. Medical College, Alappuzha for a period of 2 years. The study included 620 thyroidectomy specimens received in the Department of Pathology. All the biopsy reports were reviewed, and different lesions were categorised according to age and gender distribution. The data was analysed by standard statistical methods.Results: The commonest of the non-neoplastic lesions was nodular colloid goiter followed by lymphocytic thyroiditis, Hashimoto thyroiditis Nodular hyperplasia and thyroglossal cyst. Most common malignant lesion in this study is papillary carcinoma and benign lesion is follicular adenoma. Age group of patients ranged from 6 ½ to 84 years. The study showed a female predominance of 88.38%.Conclusions: Thyroid disorders are commonly encountered endocrine diseases. The study showed a female predominance. Peak age of incidence of thyroid lesions was between 40 and 50 years. Most common lesion was follicular adenoma and most common malignant lesion was papillary carcinoma.Histopathological examination is the mainstay for definite diagnosis and management of thyroid neoplasms.

Bocio endotorácico / Endothoracic goiter

Paciente masculino de 64 años de edad con antecedentes de hipertensión arterial y alergia al yodo, tratado con enalapril, que acudió a Consulta de Medicina Interna del Policlínico Máximo Gómez Báez de Holguín en enero de 2016 por presentar decaimiento, cansancio fácil, tos seca frecuente, palpitaciones, disfagia y cambios de la voz (ronquera), cuadro que comenzó hacía aproximadamente dos meses, y fue aumentando en intensidad sin otras complicaciones. Se realizaron los estudios de laboratorio para la valoración preoperatoria, además de los estudios de la función tiroidea, radiografías de tórax (vista antero posterior y lateral), tomografía de tórax, ecografía de la tiroides y biopsia de aspiración con aguja fina en el Hospital Clínico Quirúrgico Lucía Íñiguez de Holguín. Se encontró un bocio endotorácico y se realizó tratamiento quirúrgico que consistió en hemitiroidectomía derecha. El transoperatorio y el posoperatorio transcurrieron sin complicaciones, y el informe anatomopatológico reveló la presencia de un bocio coloide adenomatoso.

A 64-year-old male patient with a history of hypertension and iodine allergy, treated with enalapril, who came to the Internal Medicine Consultation of Máximo Gómez Báez Polyclinic in Holguín in January 2016 due to decay, easy fatigue, frequent dry cough, Palpitations, dysphagia and voice changes (hoarseness), a condition that began about two months ago, and increased in intensity without other complications. Laboratory studies were performed for preoperative assessment, in addition to studies of thyroid function, chest X-rays (anteroposterior and lateral view), chest x-ray, thyroid ultrasound, and fine needle aspiration biopsy at Lucía Íñiguez Clinical l Surgical Hospital of Holguín. An endothoracic goiter was found and surgical treatment consisted of right hemithyroidectomy. The transoperative and the postoperative period passed without complications, and the anatomopathological report revealed the presence of an adenomatous coloid goiter.

Prevalencia de enfermedades tiroideas en una población del área metropolitana de Buenos Aires / Prevalence of thyroid diseases in a population of the metropolitan area of Buenos Aires

La prevalencia de alteraciones morfológicas palpables tiroideas no supera el 8% en la población adulta. En el Hospital de Clínicas de la Universidad de Buenos Aires se llevó a cabo un programa gratuito para la detección de enfermedades tiroideas, convocándose a sujetos que desconocieran antecedentes tiroideos. Nuestro objetivo fue establecer la frecuencia de patología morfológica palpable tiroidea, en una población seleccionada de pacientes, y comparar dichos resultados con los hallazgos de un programa de detección similar, realizado en el año 2001¹. Adicionalmente, evaluar la prevalencia de alteraciones funcionales y de autoinmunidad tiroidea. Los individuos que concurrieron se dividieron en 3 grupos: Grupo 1 (n = 186) pacientes con antecedentes personales de enfermedad tiroidea conocida (excluidos del análisis); Grupo 2 (n = 184) sujetos con antecedentes familiares, otras enfermedades autoinmunes, o sintomatología que pudiera atribuirse a alteración de la función tiroidea (grupo inducido), y Grupo 3 (n = 288) sujetos que consultaron por mera curiosidad (grupo random). La función y autoinmunidad tiroidea se evaluó en 144 participantes del Grupo 3, citados al azar. En el grupo random, la prevalencia de alteraciones morfológicas tiroideas, detectadas por palpación, fue del 11,09%. Al comparar estos resultados con los obtenidos 12 años atrás en un estudio similar, realizado en nuestro hospital, no se encontraron diferencias estadísticamente significativas (8,7 vs. 11,09%; p = 0,25). En cuanto a la función tiroidea, se halló hipotiroidismo subclínico en el 6,25%, hipertiroidismo subclínico en el 0,7% y autoinmunidad en el 11% de los sujetos evaluados. En conclusión, la prevalencia de alteraciones palpables de la glándula tiroides no cambió en laúltima década. Esta investigación realizada en una población correctamente seleccionada constituye una herramienta útil para referencias futuras como población control en Argentina.

The prevalence of palpable thyroid morphological abnormalities does not exceed 8% in the adult population. A free program was conducted in the Hospital de Clínicas (University of Buenos Aires) for the detection of thyroid diseases, inviting subjects who were unaware of a history of these diseases. The aim was to establish the frequency of goitre in the selected population, as well as to evaluate the prevalence of functional disorders and thyroid autoimmunity, and to compare these results with the findings of a similar study performed in 2001¹. The subjects were divided into three groups: Group 1 (n = 186) patients with a history of previously known thyroid disorders (excluded subjects); Group 2 (n = 184) subjects with a family history of thyroid disease, other autoimmune diseases, or symptoms that could be attributed to changes in thyroid function (Induced Group), and Group 3 (n = 288) subjects who participated in this program due to mere curiosity (Random Group). Autoimmunity and thyroid function was assessed in 144 randomly selected participants in Group 3. In Group 3, the prevalence of morphological alterations of the thyroid gland was 11.09%. Comparing these results with those obtained 12 years ago in a similar study performed in our hospital, no statistically significant differences were found when the prevalence of morphological thyroid alterations were compared (8.7% vs 11.09%, p=.25). As for thyroid function, subclinical hypothyroidism was found in 6.25%, subclinical hyperthyroidism in 0.7%, and autoimmunity in 11% of subjects evaluated. It was concluded that the prevalence of palpable thyroid abnormalities had not change in the last decade. This study, made in a correctly selected population, is a useful tool for future reference as a control population in Argentina.
