ABSTRACT A type of subacute thyroiditis occurring epidemically in a factory in Helsinki was observed in 44 cases. In every case the thyroiditis followed an acute infection of the upper respiratory tract. The variation in incidence during one and a half years was in good agreement with that of the acute infection. Since Helsinki is in an endemic goitre region, the fact that the disease was of the migrating type was of great diagnostic importance. In all cases but one, the nodules have persisted. One case of asymptomatic thyroiditis was seen. In the majority of the patients the thyroid gland had been carefully palpated before the thyroiditis occurred, and in all cases the condition was followed up by the same investigator. Special attention was paid to changes in the iodine metabolism, the serum cholesterol, the electrophoretic distribution pattern of the serum proteins, and the circulating thyroid auto-antibodies. In many cases needle biopsy of the thyroid gland was performed. Thyroid function invariably returned to normal with time, although one patient remained in a hypothyroid state for about a year. In no cases were thyroid auto-antibodies found. For the beta-globulin fraction, the electrophoretic distribution pattern of the serum proteins gave values which were still not normalized in any case, and only in two cases was the alpha2-fraction normalized. The needle biopsy, when thyroid tissue was obtained, showed almost the same picture as in endemic goitre, but in some specimens nonspecific inflammatory changes were seen. Prednisolone relieved the symptoms, but did not affect the course of the disease. According to the present observation this type of epidemic thyroiditis would seem to represent a form of nonspecific subacute thyroiditis.

Abstract Objective: Incretins are expressed in thyroid tissue but without clearly-known clinical significance in human. The long-term effect of GLP-1 receptor activation on the thyroid is unknown. In the literature, liragludite-related thyroiditis has not been reported yet and here we wanted to draw attention to this association. Case Summary: A 52-year-old woman with type 2 diabetes mellitus presented with thyroid tenderness, tremor and fever. Her lab results were as follows: undetectable TSH, free T4 (FT4) = 2,4 ng/dl (0.93-1.7), free T3 (FT3) = 4.4 pg/mL (2-4.4). Erythrocyte sedimentation rate (ESR) was 60 mm/hour, C-reactive protein (CRP) was 80 mg/L. Thyroid autoantibodies were negative. USG revealed that thyroid gland was in normal localization and the right lobe was 24x22x46 mm and the left lobe was 20x21x45 mm, isthmus thickness was 5 mm. The parenchyma was heterogeneous, coarsely granular, with bilateral patchy hypoechoic areas. All these findings suggested that the patient had subacute thyroiditis. When we examine the etiological factors of subacute thyroiditis in the patient, there was no history of trauma, no previous viral or bacterial illness, contrast agent exposure. But, she had only been using liraglutide for a week. Firstly liraglutide therapy was ceased and than 20 mg prednisolone and 40 mg beta-blocker therapy was initiated. At the 8 weeks’ of cessation, patient had no symptoms. Also thyroid function tests and other laboratory values were all in normal limits. Conclusions: It has been proven by previous studies that liraglutide has several effects on the thyroid gland. Liraglutide therapy might be related to subacute thyroiditis, as well.

Radioiodine Uptake

ABSTRACT Radioiodine parameters, mainly 131I uptake by the thyroid gland were reviewed in 31 cases of subacute thyroiditis (SAT). Seven cases presented depressed uptake. The remainder had either normal or high uptakes regardless of the phase of the disease during which the measurements were made. Fifteen subjects had lived in endemic goiter areas and 16 were from Buenos Aires where 131I uptakes are high and »subendemic« conditions prevail. It is thought that under these circumstances the inhibitory effect of SAT on 131I uptake as usually seen, does not become evident. PB131I and BE131I were normal in the subjects with normal or high 131I uptakes. It is concluded that radioiodine parameters in an endemic environment do not contribute to the diagnosis of SAT. The pathophysiology of SAT is discussed in the view of the present and related studies.

Ectopic thyroid tissue is seen rarely. It is often seen in cervical midline, and rarely in other areas such as submandibular area. Diagnosis is made histopathologically by fine needle biopsy after the elimination of malignancy. In the treatment of ectopic thyroid tissue, surgical excision is mostly applied. According to our knowledge, there is no exophytic thyroid tissue reported in the literature. In this paper, a 32-year-old woman who presented with a swelling under the right jaw and found a thyroid tissue attached to the normally located thyroid gland with a fibrous band in the neck was discussed.

SUMMARY Hypophyseal tumours in mice develop after prolonged treatment with oestrogens, after injection of radioactive iodine in doses which destroy the thyroid tissue and after prolonged treatment with thiouracil-derivatives. The tumours of the hypophysis only occur in certain strains of mice and hence the genetic constitution is of importance. The origin of this difference between strains has hitherto remained completely obscure. The hypophyseal tumours in mice seen following administration of oestrogens and those observed after destruction of the thyroid gland are morphologically similar. They consist of cells staining blue to varying degrees, and they may thus be termed amphophile tumours. The possible mechanism of development of the hypophyseal tumours has been discussed.

ABSTRACT A series of cases of clinically diagnosed subacute thyroiditis comprising 11 patients is reported. Studies on the iodine metabolism, electrophoretic distribution of the serum proteins and the responsiveness to TSH were carried out. The patients were observed for periods up to 16 months from the onset of the disease. In the early phase there was an elevation of the serum PBI in a few cases and hyperthyroid signs in some, accompanied by depressed thyroid uptake of radioactive iodine and a fairly good response to TSH. Later, the thyroid grew hard and the iodine metabolism changed. In several cases there was a marked increase in the conversion ratio and the serum PB131I level. The responses to TSH was variable for different parameters of thyroid function, suggesting a state of »low thyroid reserve« as defined by Jefferies et al. (1956). Hypothyroidism developed in 3 cases; in two of them there was a response to exogenous TSH, in the third no response was seen at this stage of the disease. Cortisone and synthetic analogues seem to be of great benefit in the treatment of the acute symptoms of the disease.

Rule Out

Scintigraphy using technetium-99m (<sup>99m</sup>Tc) is the gold standard for imaging the thyroid gland in infants with congenital hypothyroidism (CHT) and is the most reliable method of diagnosing an ectopic thyroid gland. One of the limitations of scintigraphy is the possibility that no uptake is detected despite the presence of thyroid tissue, leading to the spurious diagnosis of athyreosis. Thyroid ultrasound is a useful adjunct to detect thyroid tissue in the absence of <sup>99m</sup>Tc uptake. <b><i>Aims:</i></b> We aimed to describe the incidence of sonographically detectable in situ thyroid glands in infants scintigraphically diagnosed with athyreosis using <sup>99m</sup>Tc and to describe the clinical characteristics and natural history in these infants. <b><i>Methods:</i></b> The newborn screening records of all infants diagnosed with CHT between 2007 and 2016 were reviewed. Those diagnosed with CHT and athyreosis confirmed on scintigraphy were invited to attend a thyroid ultrasound. <b><i>Results:</i></b> Of the 488 infants diagnosed with CHT during the study period, 18/73 (24.6%) infants with absent uptake on scintigraphy had thyroid tissue visualised on ultrasound (3 hypoplastic thyroid glands and 15 eutopic glands). The median serum thyroid-stimulating hormone (TSH) concentration at diagnosis was significantly lower than that in infants with confirmed athyreosis (no gland on ultrasound and no uptake on scintigraphy) (74 vs. 270 mU/L), and median free T4 concentration at diagnosis was higher (11.9 vs. 3.9 pmol/L). Six of 10 (60%) infants with no uptake on scintigraphy but a eutopic gland on ultrasound had transient CHT. <b><i>Conclusion:</i></b> Absent uptake on scintigraphy in infants with CHT does not rule out a eutopic gland, especially in infants with less elevated TSH concentrations. Clinically, adding thyroid ultrasound to the diagnostic evaluation of infants who have athyreosis on scintigraphy may avoid committing some infants with presumed athyreosis to lifelong levothyroxine treatment.

Abstract Background Ectopic thyroid tissue is a rare embryological aberration described by the occurrence of thyroid tissue at a site other than in its normal pretracheal location. Depending on the time of the disruption during embryogenesis, ectopic thyroid may occur at several positions from the base of the tongue to the thyroglossal duct. Ectopic mediastinal thyroid tissue is normally asymptomatic, but particularly after orthotopic thyroidectomy, it might turn out to be symptomatic. Symptoms are normally due to compression of adjacent structures. Case presentation We present a case of a 66-year-old male submitted to a total thyroidectomy 3 years ago, due to multinodular goiter (pathological results revealed nodular hyperplasia and no evidence of malignancy), under thyroid replacement therapy. Over the last year, he developed hoarseness, choking sensation in the chest, and shortness of breath. Thyroid markers were unremarkable. He was submitted to neck and thoracic computed tomography, magnetic resonance imaging, and radionuclide thyroid scan. Imaging results identified an anterior mediastinum solid lesion. A radionuclide thyroid scan confirmed the diagnosis of ectopic thyroid tissue. The patient refused surgery. Conclusions Ectopic thyroid tissue can occur either as the only detectable thyroid gland tissue or in addition to a normotopic thyroid gland. After a total thyroidectomy, thyroid-stimulating hormone can promote a compensatory volume growth of previously asymptomatic ectopic tissue. This can be particularly diagnosis challenging since ectopic tissue can arise as an ambiguous space-occupying lesion.

Abstract Background Ectopic thyroid is a developmental anomaly of the thyroid gland of embryological origin. Instead of having a pretracheal situation, thyroid tissue is elsewhere, most commonly in the median cervical line along the course of the thyroglossal duct. Lingual thyroid is the most common presentation. Ectopic thyroid tissue in the submandibular region has been rarely reported. Case presentation We report herein a case of a 65-year-old man admitted to our department with a complaint of a painless swelling in the left submandibular region. Conclusions Thyroid gland ectopia should be considered among the differential diagnoses of submandibular swelling. Ectopic thyroid tissue can present with the same pathology affecting the normal thyroid gland such as malignancy and hyperthyroidism.
