Abstract. Iodine prophylaxis was introduced to the moderately severe goitre endemic area in Salta, Argentina, in 1963. All thyroidectomies from a 20 year period were reviewed, and 148 thyroid malignancies carefully studied. The period from 5 to 15 years after iodization was associated with a lower frequency of follicular carcinomas and a higher frequency of papillary carcinomas than the period before and up to 5 years after prophylaxis. Lymphoid infiltration in the non-tumorous thyroid was relatively infrequent before iodine prophylaxis: it was much higher in each of the post-prophylaxis periods. These results, in agreement with other studies, support the view that an increased iodine intake is associated with an increased incidence of papillary carcinoma of the thyroid and thyroiditis.

Abstract. Endemic goitre of moderate severity was mainly found in the east of Finland in the 1930's. Studies in the 1950's showed an average daily iodine intake of 65–70 μg in the west and 50–65 μg in the east of the country. The use of iodized salt was introduced in the late 1940's but added only 15 μg of iodine to the daily intake. In the late 1950's iodine prophylaxis was intensified and the use of salt containing 25 mg KI/kg was recommended. In 1978 about 95% of all household salt used in the Savonlinna area was iodized. This region in the east of Finland has been used as an area of surveillance and studies have been carried out there in 1959, 1969 and 1979. During this period the thyroidal uptake decreased from 67 to 23% in non-goitrous subjects and from 62 to 28% in goitre patients the difference between the two last figures being statistically significant. The goitre patients also had significantly higher serum thyroxine and triiodothyronine levels. During the same period the urinary excretion of stable 127I increased from 45 μg to about 250 μg a day. Concomitantly the goitre prevalence among school children has decreased. Having been in the early 1950's in most parts 15–30% it is generally now 1–4%. It seems that the iodine intake is now adequate and that the endemia is gradually sub-siding.

ABSTRACT Introduction The most common differentiated malignant thyroid neoplasm is papillary carcinoma. Association of concurrent presence of chronic lymphocytic thyroiditis and its subtypes with differentiated epithelial thyroid carcinoma remains controversial. Objective To evaluate epidemiological factors of chronic lymphocytic thyroiditis and association between chronic lymphocytic thyroiditis and its subtypes with papillary thyroid carcinoma. Materials and methods A total of 684 patients who underwent thyroidectomy at Teaching Hospital Kandy, Sri Lanka, for a period of two-and-half years from 2013 January were reviewed. The clinical and pathological characteristics were analyzed. Chronic lymphocytic thyroiditis was diagnosed by histology. Results Thyroid malignancies were detected in 14.2% of thyroidectomy specimen, of which well-differentiated epithelial thyroid carcinoma was seen in 82%. Chronic lymphocytic thyroiditis was present in 31%, out of which 73.1% were nonspecific chronic lymphocytic thyroiditis and 26.9% were Hashimoto's thyroiditis. Gender, age, and presence of thyroiditis were significantly associated with papillary thyroid carcinoma. Males were more likely to have papillary carcinoma compared with females (p = 0.013). Those with nonspecific chronic lymphocytic thyroiditis were more likely to have papillary thyroid carcinoma (p = 0.002) compared with those without. With increasing age, proportion of lymphovascular invasion in patients with papillary thyroid carcinoma significantly (p = 0.010) decreases. None of the three factors mentioned were significant predictors of tumor focality, capsular or lymphovascular invasion. Conclusion Presence of nonspecific chronic lymphocytic thyroiditis is associated with papillary thyroid carcinoma at a given age and gender. Influence of nonspecific chronic lymphocytic thyroiditis on the prognosis of well-differentiated epithelial thyroid carcinoma needs to be investigated further with a larger sample size.

Objectives: Iodine is a trace element that is essential for the synthesis of thyroid hormone. Both chronic iodine deficiency or iodine excess have been associated with hypertrophy and hyperplasia of follicular cells in thyroid gland and the influence of thyroid hormone (T3, T4) and thyrotropin (TSH) secretion. Increase rates of the thyroid cancer are increasing after radiation exposure to 131I in children or aldolescents. Methodology: In respective published reports in literature and in combination of our previous study, dietary iodine excess goiter, iodine induced hyperthyroidism (IIH) and IIT, Iodine intake and the prevalence of papillary carcinoma (PTC), as well as the case-control and cohort studies of thyroid cancer and intake of seafood and milk products, were systematically reviewed. Relative factors that should be considered when studying the effect of dietary iodine in the development of thyroid cancer include screening programs, pathological criteria, diagnostic techniques, radioactive iodine, and standard of medical care in the studied population. Results and conclusion: In current surveys, papillary thyroid carcinoma forms the largest group of thyroid malignancies, after iodine intake excess or iodine prophylaxis where an increase in the papillary: follicular carcinoma ratio was uncovered. Also, there is clear temporal relationship in many countries between introduction of iodine intake excess especially as to radioactive iodine and an increase in incidence of PTC. Iodine goiter, IIH and IIT were also noted. Autoimmune hashimoto's thyroiditis are linked to dietary iodine. Dietary iodine intake is another care of environmental relevance factor in thyroid diseases and papillary carcinoma. Available evidence of oncogenic thyroid hormone receptor mutants from animal experiments and clinical investigation have been a shift toward the oncogenic function of human thyroid carcinoma, and also its target therapy.                    Peer Review History: Received:  May 2021; Revised:  June; Accepted:  June, Available online: 15 July 2021 Academic Editor: Ahmad Najib, Universitas Muslim Indonesia, Makassar, Indonesia, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Background. Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results. We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side of the absent lobe, left of the isthmus. Fine-needle aspiration biopsy revealed class V papillary carcinoma, but no lymph node metastases. Total thyroidectomy was performed for stage cT1bN0M0 carcinoma. Histopathology revealed normal thyroid tissues in the right lobe and isthmus, while the left lobe was absent. The mostly papillary carcinoma was adjacent to the truncated thyroid tissue, with a portion histologically consistent with poorly differentiated carcinoma. Conclusions. All previously reported cases of thyroid cancer complicated by hemiagenesis have represented carcinoma occurring within the present lobe. This case is extremely rare.

Abstract Background Parathyroid carcinoma is a rare endocrine malignancy, rarer when synchronous with a non medullary well differentiated thyroid carcinoma. Parathyroid carcinoma accounts of 0.005% of all malignant tumors and it is responsible for less than 1% of primary hyperparathyroidism. The intrathyroidal localization of a parathyroid gland is not frequent with a reported prevalence of 0.2%. Carcinoma of parathyroids with intrathyroidal localization represents an even rarer finding, reported in only 16 cases described in literature. The rare constellation of synchronous parathyroid and thyroid carcinomas has prompted us to report our experience and perform literature review. Case presentation We herein report a case of a 63-years-old man with multinodular goiter and biochemical diagnosis of hyperparathyroidism. Total thyroidectomy with radio-guide technique using gamma probe after intraoperative sesta-MIBI administration and intraoperative PTH level was performed. The high radiation levels in the posterior thyroid lobe discovered an intrathyroidal parathyroid. Microscopic examination revealed a parathyroid main cell carcinoma at the posterior thyroidal left basal lobe, a classic papillary carcinoma at the same lobe and follicular variant of papillary carcinoma at the thyroidal right lobe. To the best of our knowledge, this is the first case documenting a synchronous multicentric non medullary thyroid carcinomas and intrathyroidal parathyroid carcinoma. Conclusions Our experience was reported and literature review underlining challenging difficulties in diagnostic workup and surgical management was carried out.

Background: The aim of this retrospective study was to investigate clinical and pathological characteristics of the tall cell variant of papillary thyroid carcinoma compared to conventional variants. Methods: The clinical records of patients who underwent surgical treatment between 2009 and 2015 were analyzed. The patients were divided into two groups: those with a histopathological diagnosis of tall cell papillary carcinoma were included in Group A, and those with a diagnosis of conventional variants in Group B. Results: A total of 35 patients were included in Group A and 316 in Group B. All patients underwent total thyroidectomy. Central compartment and lateral cervical lymph node dissection were performed more frequently in Group A (42.8% vs. 18%, p = 0.001, and 17.1% vs. 6.9%, p = 0.04). Angiolymphatic invasion, parenchymal invasion, extrathyroidal extension, and lymph node metastases were more frequent in Group A, and the data reached statistical significance. Local recurrence was more frequent in Group A (17.1% vs. 6.3%, p = 0.02), with two patients (5.7%) in Group A showing visceral metastases, whereas no patient in Group B developed metastatic cancer (p = 0.009). Conclusions: Tall cell papillary carcinoma is the most frequent aggressive variant of papillary thyroid cancer. Tall cell histology represents an independent poor prognostic factor compared to conventional variants.

BACKGROUND Papillary thyroid carcinoma is the most common malignancy of the thyroid gland. Fine Needle Aspiration Cytology (FNAC) is a rapid, safe and economic procedure, and has a sensitivity approaching of 93.5 % and specificity close to 90 % for diagnosing papillary thyroid carcinomas. This study aims at correlating the cytological and histological diagnosis to arrive at the rate of concordance and discordance, identify variants of papillary thyroid carcinoma (PTC) on cytology and discuss the cytological mimics of PTC. METHODS Data from cases was collected over a period of three years (2015 - 2018). A descriptive study was done. Cases from Osmania General Hospital representing histologically proven cases of papillary carcinoma thyroid along with their corresponding cytological findings were analysed. Cytosmears were obtained from fine needle aspiration of thyroid lesions using a 26-gauge needle, stained with haematoxylin and eosin (H&E). Thyroidectomy specimens were fixed in 10 % buffered formalin, grossed and paraffin embedded. After processing, sections obtained by microtomy were stained with H & E for histopathologic evaluation. RESULTS The institute received a total of 258 thyroid specimens for histopathology and 686 cases for thyroid FNAC over a period of three years. This study includes 70 cases which had both cytology and histopathology correlation at our institution. 65 cases were diagnosed as PTC on histopathology and correct diagnosis was made on cytology with 73.8 % concordance (48 / 65 cases) and discordance was seen in 26.1 % (17 / 65 cases). 5 cases were misdiagnosed on cytology as PTC, and on histopathological examination were diagnosed as non-PTC. CONCLUSIONS Fine needle aspiration shows variable accuracy for PTC, ranging from 65 % to 90 %. The architectural arrangement of cells in papillary fragments and presence of nuclear features in majority of cells is diagnostic of the conventional variant of PTC. The other variants however, pose a diagnostic dilemma on account of their architectural variation, altered cytomorphology and the scant presence of nuclear features. An increase in the awareness of cytomorphology of variants and also of the mimics of PTC helps improve the diagnostic accuracy on FNAC.

Iodine is an essential component of thyroid hormones, but excessive iodine intake can lead to thyroid dysfunction. Traditionally, Korean mothers consume brown seaweed soup (miyeokguk), a high source of iodine, after childbirth. There is controversy regarding the effects of excessive postpartum iodine intake on the health of mothers and infants. Thus far, there have been no nationwide large-scale surveys regarding the status of iodine intake among postpartum women in Korea. Therefore, we conducted a nationwide survey of postpartum dietary iodine intake among Korean women. In total, 1054 Korean women aged ≥19 years, at less than 8 weeks postpartum, participated in this survey. Dietary data were collected using self-reported 2-day dietary records, along with before-and-after meal photos. To evaluate the correlation between dietary iodine and urinary iodine excretion (UIE), spot urine, and 24 h urine samples were collected from 98 and 29 participants, respectively. The mean daily iodine intake among all participants was 2945.6 μg, and it gradually decreased over time after childbirth. Dietary iodine intake was significantly correlated with 24 h UIE (r = 0.396, p < 0.05) and spot urine UIE (r = 0.312, p < 0.05). Follow-up studies are required to examine the influence of excessive postpartum iodine intake on thyroid health in mothers and their infants.
