Radioiodine therapy in elderly patients with subclinical hyperthyroidism due to non-voluminous nodular goiter and its effect on bone metabolism / Terapia com radioiodo em pacientes idosos com hipertireoidismo subclínico por bócio nodular não volumoso e efeito sobre o metabolismo ósseo

OBJECTIVE: To evaluate 131I therapy in elderly patients with subclinical hyperthyroidism (SCH) due to nodular disease and who did not receive antithyroid drugs (ATDs), and the effect of the treatment on bone metabolism. SUBJECTS AND METHODS: Thirty-six patients with TSH ≤ 0.1 mIU/L and non-voluminous goiter (< 60 cm³) were studied. Bone mineral density (BMD) was assessed in 17 women with osteopenia. RESULTS: Mean 24-h 131I uptake was 17.5%. Symptoms of thyrotoxicosis were reported by two (5.5%) patients in the first week after therapy. One year after radioiodine treatment, SCH was resolved in 30 (83.3%) patients, and hypothyroidism was detected in one (2.7%). In the patients in whom TSH returned to normal, femoral and lumbar spine BMD increased by 1.9% and 1.6%, respectively, in average. CONCLUSIONS: In elderly patients with SCH and non-voluminous goiter, radioiodine not preceded by ATDs is a safe and effective therapeutic alternative. Resolution of SCH has beneficial effects on BMD in postmenopausal women with osteopenia.

OBJETIVO: Avaliar a terapia com 131I em idosos com hipertireoidismo subclínico (HSC) por doença nodular que não receberam drogas antitireoidianas (DATs) e o efeito no metabolismo ósseo. SUJEITOS E MÉTODOS: Trinta e seis pacientes com TSH ≤ 0,1 mUI/L e bócio não volumoso (< 60 cm³) foram estudados. Dezessete mulheres com osteopenia foram submetidas à avaliação da densidade mineral óssea (DMO). RESULTADOS: Captação média de 131I em 24 h foi 17,5%. Sintomas de tireotoxicose foram reportados por dois pacientes (5,5%) na primeira semana após a terapia. Um ano após o radioiodo, HSC foi resolvido em 30 pacientes (83,3%) e hipotireoidismo ocorreu em 1 (2,7%). Nas pacientes que normalizaram o TSH, DMO em fêmur e coluna lombar incrementou em média 1,9% e 1,6%, respectivamente. CONCLUSÕES: Em idosos com HSC e bócio não volumoso, radioiodo, não precedido de DATs, é uma alternativa terapêutica segura e eficaz. Resolução do HSC tem benefício na DMO em mulheres menopausadas com osteopenia.

Combination Therapy of Temporary Tracheal Stenting and Radiofrequency Ablation for Multinodular Thyroid Goiter with Airway Compression

We report a case of multinodular thyroid goiter in an 80-year-old man who successfully underwent tracheal stent placement for respiratory distress caused by the thyroid goiter and following two radiofrequency (RF) ablation sessions performed for thyroid volume reduction. This sequential treatment allowed elective stent removals four weeks after the second RF ablation session because the thyroid volume had been progressively reduced. Combination therapy of temporary airway stenting and RF ablation for the treatment of thyroid goiter has two advantages, i.e., immediate reliefs of dyspnea with airway stenting and reductions of the thyroid volume with RF ablation, and thus, allowing symptom reliefs even after the stent removals.

Insuficiência respiratória aguda secundária a bócio mergulhante da tireoide / Acute respiratory insufficiencysecondary to substernal thyroid goiter

Relato de caso de bócio mergulhante (BM) em idosa com longa história de bócio nodular tóxico (BNT) e que evoluiu com insuficiência respiratória aguda enquanto aguardava cirurgia eletiva para extirpação do bócio. A evolução das complicações respiratórias dessa paciente sugere que o tratamento cirúrgico do BM em idosos deveria ser feito o mais breve possível, após o surgimento de sintomatologia respiratória, para evitar complicações.

Case report of substernal thyroid goiter in an elderly woman with long record of toxic nodular goiter that progressed to acute respiratory insufficiency while waiting for elective surgery for extirpation of goiter. The development of respiratory complications suggests that the surgical treatment of substernal thyroid goiter affecting elderly people should be pursuit as soon as possible after the appearance of respiratory symptomatology as a means of avoiding complications.

frequency of malignancy in nodular goiter - a single center study

To find out the frequency of malignancy in nodular goiters. A total of 204 cases were studied in the department of ENT and Head and Neck surgery, Hayatabad Medical Complex, Peshawar. The duration of this descriptive study was from June 1, 2008 to May 31, 2010. After taking informed consent, a detailed history was obtained. Clinical and laboratory investigations were carried out as an aid to diagnosis and determine the patients' fitness for surgery. Patients with nodular goiters were categorized into two categories i.e., Solitary thyroid nodule and multinodular goiter. Surgically resected thyroid specimens were examined histopathologically. The data was analyzed using SPSS 16.0 for windows to determine the frequency of malignancy in nodular goiter. Ages of the patients ranged from 17 to 84 years with a mean age of 37 +/- 12.48 years. The male to female ratio was 1:3:5. 18.14% cases presented as solitary thyroid nodules [STN] and 81.86% as multinodular goiters [MNG]. Out of the total 83.82% cases were benign and 16.18% cases were malignant. The prevalence of malignancy in multinodular goiter was 14.37% and in the solitary thyroid nodules as 24.32%. Papillary carcinoma was the commonest malignancy followed by follicular carcinoma. The prevalence of cancer is significant in nodular goiters and these malignant tumours are usually of the papillary type. Solitary thyroid nodules have more chances of being malignant than multinodular goiter

Acute respiratory failure caused by neglected giant substernal nontoxic goiter / Insuficiência respiratória aguda resultante de bócio atóxico mergulhante gigante negligenciado

Substernal goiter is usually defined as a goiter in which the thyroid mass has descended the plane of the thoracic inlet or if more than 50 percent of the thyroid mass is located below the thoracic inlet. Substernal goiters may be asymptomatic or may present with symptoms caused by compression of adjacent organs. Acute respiratory failure is rare in cases of substernal goiter. In cases of symptomatic substernal goiter the treatment is surgical by thyroidectomy. We present a rare case of a giant substernal nontoxic goiter which caused acute respiratory failure which was treated by urgent thyroidectomy through a T-incision.

Geralmente se define o bócio mergulhante como o bócio em que a massa da tireoide descende ao plano da cavidade torácica ou mais do que 50 por cento da massa tireoidiana se localiza abaixo da cavidade tireoidiana. O bócio mergulhante pode ser assintomático ou apresentar sintomas resultantes da compressão de órgãos adjacentes. A insuficiência respiratória aguda é rara nos casos de bócio mergulhante. Nos casos de bócio mergulhante sintomático, o tratamento indicado é cirúrgico, por tireoidectomia. Nesse relato, descreveu-se um caso raro de bócio atóxico mergulhante gigante negligenciado que resultou em insuficiência respiratória aguda e foi tratado com tireoidectomia de emergência com incisão em T.

Disfunção hepática aguda em paciente com hipertireoidismo e hepatite por vírus B: recuperação após plasmaférese e tireoidectomia - relato de caso / Acute hepatic failure in a patient with hyperthyroidism and virus B hepatitis: recovery after plasmapheresis and thyroidectomy - a case report

Paciente masculino, 31 anos, internado com quadro de dor abdominal, náuseas, vômitos, icterícia e febre, iniciado há duas semanas. História de hipertireoidismo e tratamento irregular com propiltiuracil há dois anos, interrompeu a medicação quando iniciou o quadro atual. Apresentava bócio difuso, cerca de 120 g, T4L 22,7 ng/dL (VN 0,8-1,9 ng/dL); TSH < 0,002 µUI/mL (VN 0,4-5 µUI/mL). Transaminases, bilirrubinas total e direta séricas elevadas. Foi mantido sem antitireoidiano e iniciado propranolol até a dose de 480 mg/dia. Ultra-sonografia de abdome foi normal e sorologias para hepatites A, B e C indicaram infecção aguda por vírus B. Ocorreu piora da função hepática e manutenção de níveis elevados de hormônios tireoidianos. Visando evitar necessidade futura de antitireoidiano, obter rápida normalização dos níveis de hormônios tireoidianos e em virtude do tamanho do bócio foi indicado tireoidectomia. O paciente foi submetido a uma sessão de plasmaférese terapêutica, imediatamente antes da cirurgia, e tireoidectomia subtotal sem intercorrências. No quinto dia após a cirurgia, o paciente apresentava melhora da função hepática e baixos níveis séricos de T4 livre. Concluímos que o hipertireoidismo prévio pode exacerbar e perpetuar a disfunção hepática causada por hepatite viral aguda e que a plasmaférese é um meio rápido, seguro e eficaz de reduzir os níveis de hormônio tireoidiano, permitindo uma tireoidectomia bem-sucedida em pacientes com tireotoxicose grave.

A 31-year-old man admitted with abdominal pain, nauseas, vomiting, jaundice and fever that had began 2 weeks before. He had a history of hyperthyroidism and an irregular treatment with propylthiouracil (PTU) for 2 years. He had stopped PTU when the current symptoms started. The patient presented diffuse goiter, about 120g, FT4 22.7 ng/dL (N: 0.8 - 1.9 ng/dL); THS < 0.002 µUI/mL (N 0.4-5 µUI/mL). Transaminases, serum total and direct bilirubins were increased. He was kept without PTU and propranolol was started and increased until the dose of 480 mg/day. Abdominal ultrassonography was normal and serologic markers for hepatitis A, B and C pointed to acute virus B hepatitis. The patient presented a worse of hepatic function and elevated thyroid hormones levels. To avoid the future need of antithyroid drugs, to get a fast normalization of thyroid hormones levels and because of the goiter size thyroidectomy was recommended. The patient underwent one therapeutic plasmapheresis session just before the surgery. A total thyroidectomy was performed without complications. At the 5th day after surgery the patient presented improvement of hepatic function and low FT4 serum levels. We concluded that preexisting hyperthyroidism may aggravate or perpetuate a hepatic failure caused for acute viral hepatitis and plasmapheresis is a rapid, reliable and effective way to lower thyroid hormones serum levels, allowing a successful thyroidectomy in patients with severe thyrotoxicosis.

Glycemic status in hyperthyroid subjects.

This was an observational case-control study carried out in the Department of Biochemistry, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka jointly with the 'Thyroid and Endocrine Clinic' of the same institution during the period of January 2002 to December 2002. Sixty-five (65) newly diagnosed hyperthyroid patients between 20-60 years of age were studied, where forty-five (45) were Graves' disease and twenty (20) were TMNG (Toxic multinodular goiter) patients. Thyrotoxicosis was diagnosed by history, clinical examination and biochemical investigations- FT4, TSH, and Radioactive iodine uptake (RAIU) test. Thirty (30) age and sex matched healthy subjects were taken as control. The mean age was 33.02+/-9.24 years in Graves' disease and 37.55+/-9.49 years in TMNG. Female predominance observed in both the diseases. Glucose intolerance was found in 72.3% of thyrotoxic patients, which is much higher than European population. Our study showed Diabetes mellitus (DM) in 11% of Graves' disease patients. The incidence of DM in Graves' disease was slightly higher in our population. Incidence of DM in TMNG in our study was much lower (5%) than that of Graves' disease (11%) but the incidence of IGT (Impaired glucose tolerance) in TMNG was more (85%) in relation to Graves' disease (54%). Percentage of RAIU was more marked in Graves' disease than TMNG. There is a significant positive correlation (p<0.05) between plasma glucose and FT4 in Graves' disease. Glucose intolerance is frequently found in Thyrotoxic patients.

role of pharyngo-esophageal manometery in the evaluation of dysphagia in patients with multinodualr goiter

The incidence of dysphagia was reported in up to 35% of goiter patients with mild to moderate severity. Pharyngo-esophageal manometry is a diagnostic test that provides both quantitative and qualitative assessment of pressure, coordination and motility for both the pharynx and esophagus

Nodular goitre. Presentation and prevalence of complications.

OBJECTIVE: To evaluate the presentation and prevalence of different preoperative complications in patients with nodular goitre. DESIGN: Patients of either age and sex with nodular thyroid swelling [goitre] admitted from January 1992 to November 1992. SETTING: Surgical Unit-Il of Services Hospital, Lahore SUBJECTS: Forty patients of either sex and age presenting with nodular goitre were included. MAIN OUTCOME MEASURE: Mode of presentation and prevalence of different preoperative complications in patients with nodular goitre. Peak incidence of nodular goitre was in age group between 20-40 years. 75% patients belonged to this group with male to female ratio being 1:4. Simple non toxic multi-nodular goitre was present in 57.50%, adenoma in 27.50%, toxic adenoma in 2.50%, secondary toxic goitre in 2.50% where as 10% patient had malignant goitre. 70% of patients of present study did not have any symptoms other than a swelling in front of neck. 30% patients had some symptoms like respiratory obstruction in 50%, dysphagia in 8.33%, hoarseness in 16.66%, weight loss and anorexia in 33,33%, toxicity in 16.66"lo, histo-pathological evidence of malignancy was found in 10% of patients and papillary carcinoma was heading the list

Long-term results of two schedules of treatment for toxic multinodular goitre with radioiodine therapy.

Results of the long-term effects of two schedules of radioiodine therapy I131 in 130 toxic multinodular goitre patients were evaluated. Seventy five patients (group I) were treated with low doses and 55 patients (group II) with calculated high doses adjusted for thyroid weight (0.5-1 mci/g) and radioiodine uptake. Follow up (mean +/- SEM) was 4.5 +/- 0.4 years and 4.8 +/- 0.6 years respectively (P > 0.1). At the end of follow up, hyperthyroidism was successfully reversed in 78% (Group I) and 82% (Group II). In group I hypothyroidism was present in 5% of patients, while it was 12.5% in group II patients. The total dose per gram of thyroid tissue was not significantly different in both the groups (.058 mci +/- .0054 VS .073 +/- .0054 mci/g). However in group II the number of I131 administration was significantly lower (1.5 +/- 0.2) than in group I (3.2 +/- 0.4). The percentage of patients who were adequately treated in Group II with single dose was more as compared in group I (62% in group II versus 40% in group I). Euthyroidism was reached in a shorter time after treatment in group II (median time 0.8 year in group II Vs 1.1 yrs in group I) It is concluded that radioiodine is an effective treatment for toxic multinodular goitre with a significant low incidence of post therapy hypothyroidism in patients treated with low doses as compared to higher doses of radioiodine therapy.

Efficacy of standard ten millicurie dose of radio-iodine in management of autonomously functioning toxic thyroid nodules.

Therapeutic effect of radio-iodine treatment on thyroid patients with autonomously functioning toxic thyroid nodule was evaluated. Fifty one patients were given a standard dose of 10 mci of radioiodine (I-131) and were followed up for 2-3 years. The failure rate (relapse after 10 mci of radioiodine) of this regime was 10%. It was found that the nodules less than or equal to 3 cms. in size were completely cured after a dose of 10 mic. of radio-iodine therapy, over a follow up period of next 6 months. Patients having nodules larger than 3 cms. relapsed after first dose of 10 mci of radio-iodine, but were cured completely after the second dose of 10 mci of radio-iodine therapy. Tri-iodothyronine (T3) and thyroxine (T4) values were both found to be high before giving treatment in all the cases. Only one case developed hypothyroidism after radioiodine therapy.

Carcinoma medular da tireóide associado a bócio nodular autônomo: relato de caso / Medullary carcinoma of the thyroid associated with an autonomously functioning nodule: report of case

Os autores relatam caso de paciente feminina com 55 anos, que mostrou carcinoma medular da tireóide associado a bócio nodular autônomo compensado. Na evoluçao evidenciou metástase pulmonar iodocaptante, que se beneficiou do tratamento com 176mCi de 131-I. A despeito da raridade desta associaçao, sugerem que os nódulos quentes tenham conduta cirúrgica e que o tratamento com radioiodo seja considerado como alternativa nas metástases captantes.

Bócio uninodular autônomo atóxico: estudo retrospectivo de 31 casos / Solitary nontoxic autonomously functioning nodules: retrospective study of 31 cases

Estudamos retrospectivamente o quadro clínico e laboratorial, assim como a evoluçäo, de 31 pacientes com diagnóstico de bócio uninodular autônomo atóxico (BUAA), acompanhados na Disciplina de Endocrinologia da Escola Paulista de Medicina de 1983 a 1989. Eram 29 mulheres e 2 homens, com idades variando de 18 a 68 anos, eutiroidianos clínica e laboratorialmente à apresentaçäo; 18 mostravam tecido extra-nodular parcialmente captante e 13 näo evidenciavam tecido extra-nodular captante; no teste TRH 8 tinham resposta abolida, 8 resposta parcial e 4 resposta normal; todos os 13 casos que se submeteram à supressäo com T3 tiveram a resposta abolida; todos os 12 casos que realizaram o teste de estímulo com TSH exógeno apresentaram resposta positiva. Näo houve correlaçäo entre o aspecto do nódulo ao mapeamento e a resposta do TSH ao TRH, nem entre o teste do TRH e o teste de supressäo com T3. Quanto ao seguimento, 4 pacientes evoluiram para o hipertiroidismo no espaço de 1 a 3 anos, enquanto que um apresnetou hipotiroidismo por tiroidite de Hashimoto; além disso, indicamos ciruriga ou radioterapia profiláticas em outros 7 casos por possuirem nódulos grandes ou doenças associadas

Tireoidite aguda supurativa causada por Escherichia coli associada a hipotireoidismo primário / Acute suppurative thyroiditis due to Escherichia coli associated with primary hypothyroidism

Os autores apresentam um caso de tireoidite agudo supurativa em um paciente de 46 anos que era portador de bócio de longa duraçäo. A infecçäo tireoidiana foi causada por Escherichia coli, um germe muito pouco freqüente nesta situaçäo. O paciente desenvolveu, concomitantemente ao processo infeccioso, manifestaçöes laboratorias de hipotireoidismo primário. Relata-se também o emprego inédito da cintilografia com Ga no diagnóstico desta afecçäo

Histopathologic study of the so called 'palpation thyroiditis'

We have reviewed 1066 thyroid lesions and compared the relative incidence of the so called 'palpation thyroiditis' between autoimmune thyroiditis and normal thyroid parenchyme surrounding the nodular thyroid lesion and also discussed the pathogenesis of palpation thyroiditis. The typical histopathologic features of 'palpation thyroiditis' were seen in 275 cases among 467 adenomatous goiters and in none of the autoimmune thyroiditis. We here in this paper suggest that the so called 'palpation thyroiditis' is not merely a secondary phenomenon to mechanical follicular damage by vigorous palpation, but this lesion more likely develops in conditions where certain types of physiologic alteration has occurred in follicular basement membrane, just like a pathogenesis of subacute granulomatous thyroiditis.
