Bócio em bovinos / Goiter in cattle

Bócio é o aumento não inflamatório e não neoplásico da glândula tireoide em animais adultos e recém-nascidos. Uma das principais causas envolvidas é a deficiência nutricional de iodo. Relata-se neste trabalho, a ocorrência de três surtos de bócio em bovinos. Na primeira propriedade (Propriedade A), 60 bezerros foram afetados, sendo que 20 morreram logo após o nascimento, 30 recuperaram-se e 10 permaneceram doentes e tiveram remissão dos sinais apenas após tratamento parenteral com iodo. Na segunda propriedade (Propriedade B) uma vaca e seu feto foram acometidos e na terceira (Propriedade C) dois bezerros foram afetados. Os principais sinais clínicos observados nos bezerros foram aumento de volume bilateral na região cervical ventral, emagrecimento, dificuldade respiratória, hipotricose e desenvolvimento corpóreo retardado. Na propriedade A foi relatada ainda a ocorrência de abortamentos. Macroscopicamente, os bezerros e o feto apresentavam tireoide aumentada, vermelho-escura, com vascularização evidente e edema subcutâneo cervical. No surto dois também foi observado, à necropsia, aumento de volume da glândula tireoide da vaca. Microscopicamente, a tiroide dos bezerros e do feto apresentava folículos tireoidianos hiperplásicos, heterogêneos, destituídos de coloide e com interstício acentuadamente vascularizado. A tireoide da vaca era semelhante à dos bezerros, no entanto, possuía quantidade maior de coloide. Em todos os casos a suplementação mineral era realizada por meio da mistura de sal mineral com sal branco. Na Propriedade A o sal branco era não iodado e misturado em partes iguais com o sal mineral. Na Propriedade B o sal também era misturado a um sal branco não iodado na proporção e 1:2, respectivamente. Na Propriedade C o sal mineral e o sal branco não iodado eram ofertados em cochos separados no campo e, segundo relato do proprietário, os animais priorizavam o consumo do sal branco. Em todas as propriedades acompanhadas foi recomendada a interrupção da adição de sal branco na mistura mineral e a administração de iodo aos bezerros acometidos. Após essas medidas não foram observados novos casos nas propriedades. Apesar de ser uma enfermidade bem conhecida, ainda são poucos os relatados de casos de bócios em bovinos no Brasil. Além disso, pouco se sabe sobre as reais deficiências minerais de cada região, e que simples orientações de manejo nutricional ainda são necessárias.(AU)

Goiter is a non-inflammatory and non-neoplastic enlargement of the thyroid gland in adults and neonates. One of the main causes involved is the nutritional deficiency of iodine. In this study three outbreaks of goiter in cattle are reported. In the first outbreak (Farm A) 60 calves were affected, of which 20 died soon after birth, 30 recovered and 10 remained sick. In the second outbreak (Farm B) a cow and its fetus were affected and in the third outbreak (Farm C) two calves were affected. The main clinical signs observed were bilaterally enlarged thyroid glands, weight loss, respiratory distress, hypotrichosis and myxedema. Additionally in the Farm A abortions were reported. Macroscopically the thyroid of the calves and fetus was enlarged, dark red with evident vascularization and cervical subcutaneous edema. In the Farm B the cow showed enlarged thyroid gland as well. Microscopically the calves and the fetus had hyperplastic and heterogeneous thyroid follicles with absence of colloid and vascularized interstitium. The thyroid of the cow was also hyperplastic, but had higher amount of colloid. In all outbreaks the mineral supplementation was performed by mixing non-iodized white salt with the mineral mixture. On the property A the white salt was non-iodized and mixed in equal parts with the mineral salt. At property B the salt was also mixed to a non-iodized white salt in ratio and 1:2, respectively. In the property C, mineral salt and non-iodized white salt were offered in separate troughs in the field, and according to the owner's report the animals prioritized the consumption of white salt. In all the monitored properties it was recommended to stop the addition of white salt in the mineral mixture and the administration of iodine to the affected calves. After these measurements no new cases were observed in the properties. Despite being a well-known disease, there are still few reported cases of goiter in cattle in Brazil. Moreover, little is known about the actual mineral deficiencies of each region, and that simple nutritional management guidelines are still needed.(AU)

Goitres volumineux : traitement chirurgical au CHU du Point G

But : Décrire le traitement chirurgical des goitres volumineux au CHU du Point G.Patients et méthodes : Il s'agissait d'une étude réalisée entre 2009 et 2014 au CHU du Point G. Elle a porté sur les goitres ayant une hauteur et ou une largeur supérieure ou égale à 10 centimètres.Résultats : Nous avons colligé les dossiers de 115 cas de goitres volumineux. Les patients étaient de sexe féminin dans 87,8% des cas. Nous avons trouvé une dyspnée dans 40% descas (n=46), une dysphonie dans 13,0% des cas (n=15) et une dysphagie dans 8,6% des cas(n=10). La hauteur moyenne de la tuméfaction a été de 12,1 cm ± 3,5 et la largeur moyenne de 14,4 cm ± 5,4. Les goitres étaient hyperthyroïdiens chez 21,7% des patients (n=25) et multinodulaires dans 96,5% des cas. Il y avait 3 cas de cancer de la thyroïde. Tous les cas d'hyperthyroïdie ont été équilibrés par un anti thyroïdien de synthèse associé au Beta bloquant et au lugol fort avant la chirurgie. Le traitement chirurgical a constitué en une thyroïdectomie subtotale dans 97,4% des cas (n=112) et une thyroïdectomie totale dans 2,6% des cas (n=3). Les suites opératoires ont été simples dans 81,7% des cas (n=94). 18,3% de complications ont été notées(hématome compressif, Dysphonie, Dyspnée, Hyperparathyroïdie, Hypothyroïdie). La mortalité post opératoire était nulle.Conclusion : Le traitement chirurgical passe par la connaissance de l'anatomie de la région cervicale et une technique de thyroïdectomie bien codifiée

Suivi hormonal post thyroidectomie : Etude prospective à propos de 112 cas opérés à l'Hôpital National de Niamey de Mars 2014 à Avril 2015

Le goitre est la maladie endocrinienne la plus répandue au monde. L'objectif de notre étude est d'évaluer l'influence de la thyroïdectomie sur la fonction hormonale dans le service de chirurgie générale de l'hôpital national de Niamey. A cet effet nous avons recueilli les données relatives à 112 cas, ayant bénéficié d'une thyroïdectomie, entre mars 2014 et avril 2015. Le sexe féminin est prédominant avec 96,4% soit un sex ratio de 0,04, la tranche d'âge comprise entre 30-39 ans est la plus touchées avec 37,5% et une moyenne de 41,2 ans. La durée d'évolution du goitre est plus de 4 ans dans 33% des cas avec une moyenne de 7,5 ans et des extrêmes allant de 5 mois à 20 ans. Le premier motif de consultation est la tuméfaction cervicale antérieure. L'échographie a montré un aspect hyperéchogène dans 58% des cas. La radiographie cervicale est pathologique dans 76% des cas. Le goitre euthyroidien est majoritaire avec 89,2%. Sur le plan thérapeutique, la loboisthmectomie est le geste le plus pratiqué avec 43,7%, suivi de la thyroïdectomie subtotale avec 34%, thyroïdectomie totale 16% et la nodulectomie avec 9%. Le bilan hormonal post opératoire a objectivé 16 cas (14,3%) d'hypothyroïdie à 1 mois, 30 cas (26,7%) à 3 mois et à 6 mois et 2 cas (1,8%) à 1 an. La corrélation entre les gestes chirurgicaux et le bilan hormonal à 6 mois nous a permis de faire les constats suivants : dans les 30 cas d'hypothyroïdie, 16 étaient liées à la thyroïdectomie totale, 8 patients des loboisthmectomies et 6 des thyroïdectomies subtotales. A 1 an, nous avons constatés au total 2 cas d'hypothyroïdie liée à la thyroïdectomie totale, malgré la subtutition hormonale. Partant de ce résultat, nous pensons qu'il faut conserver un peu du tissu thyroïdien que ça soit le lobe ou la lame postérieure afin d'éviter la prescription des hormones thyroïdiennes

Clinical, biochemical & cytomorphologic study on Hashimoto’s thyroiditis.

Background & objectives: Despite, the extensive salt iodization programmes implemented in India, the prevalence of goiter has not reduced much in our country. The most frequent cause of hypothyroidism and goiter in iodine sufficient areas is Hashimoto’s thyroiditis (HT). This study records the clinical presentation, biochemical status, ultrasonographic picture and cytological appearance of this disease in a coastal endemic zone for goiter. Methods: Case records of patients with cytological diagnosis of HT were studied in detail, with reference to their symptoms, presence of goiter, thyroid function status, antibody levels and ultrasound picture. Detailed cytological study was conducted in selected patients. Results: A total of 144 patients with cytological proven HT/lymphocytic thyroiditis were studied. Ninety per cent of the patients were females and most of them presented within five years of onset of symptoms. Sixty eight per cent patients had diffuse goiter, 69 per cent were clinically euthyroid and 46 per cent were biochemically mildly hypothyroid. Antibody levels were elevated in 92.3 per cent cases. In majority of patients the sonographic picture showed heterogeneous echotexture with increased vascularity. Cytological changes were characteristic. Interpretation & conclusions: our study showed predominance of females in the study population in 21-40 yr age group with diffuse goiter. We suggest that in an endemic zone for goiter, all women of the child bearing age should be screened for HT.

Uso de mascarilla laríngea en cirugía tiroidea / Laryngeal mask in thyroid surgery

Introducción: Tradicionalmente la cirugía tiroidea ha sido practicada bajo anestesia general con intubación endotraqueal. Sin embargo, tomando en cuenta que el riesgo de intubación difícil aumenta en presencia de bocio, que el paso del tubo endotraqueal puede lastimar las cuerdas vocales y que su colocación requiere de relajación muscular y de una laringoscopia con estimulación simpática, el uso de mascarilla laríngea (ML) en cirugía tiroidea pareciera ser una buena alternativa. Con el propósito de determinar si el tamaño del bocio, el diagnóstico de cáncer, el grado de Mallampati y la extensión de la cirugía tiroidea inciden en la dislocación de la ML, se diseñó un estudio incluyendo pacientes con patología tiroidea operados bajo anestesia general con Mascarilla laríngea clásica (MLc). Diseño, lugar y participantes: Se presenta una serie prospectiva de casos, con 168 pacientes sometidos a cirugía tiroidea bajo anestesia general con MLc, operadosde marzo de 1999 a agosto del 2008 en los hospitales Universitario Esperanza y Nuestra Señora del Pilar de la ciudad de Guatemala. Su uso se consideró exitoso cuando la cirugía pudo ser completada con la MLc sin necesidad de sustituirla por intubación endotraqueal. Resultados:La edad promedio de los pacientes fue de 45 años, 148 (88%) fueron del sexo femenino y 20 (22%) del sexo masculino, el tamaño promedio de la glándula tiroides fue de 9.03cm, 166 (99%) tenían Grado I-II de Mallampati, 119 (71%) fueron operados por enfermedad benigna y 49 (29%) por cáncer, a 77 (46%) se les practicó una lobectomía, a 85 (51%) una tiroidectomía total y a 6 (3%) un vaciamiento ganglionar cervical. De los 168 pacientes operados, en 159 (95%) el procedimiento quirúrgico pudo completarsecon la MLc y en 9 pacientes (5%), la MLc fue sustituida por un tubo endotraqueal. Después de análisis univariados y multivariados se pudo establecer que: ni la edad, el sexo, el tamaño de la glándula tiroides, el grado de Mallampati, el diagnóstico histopatológico, ni la extensión de la cirugía, se asociaron estadísticamente con dislocación de la MLc y la necesidad de sustituirla por un tubo endotraqueal. Conclusiones: El uso de la MLc en cirugía tiroidea es posible independientemente del tamaño del bocio, del grado de Mallampati, de la presencia de cáncer y de la extensión de la cirugía.

Background:Traditionally thyroid surgery has been performed under general anesthesia with an endotracheal tube; in the presence of large goiters management of the upper air way using and endotracheal tube can prove to be difficult causing trauma to the vocal chords and requiring a laryngoscopy after neuromuscular blockade. The use of a laryngeal mask could be a valid option in these patients. The aim of this study was to determine if thyroid surgery could be completed using a laryngeal mask. In order to do this, we analyzed if goiter size pathologic diagnosis, Mallampati score and surgical procedure were associated with rates of dislodgement of a classic laryngeal mask (MLc) during thyroid surgery. Design, setting and participants: We present a prospective series of 168 patients who were submitted to thyroid surgery under general anesthesia using an MLc. All surgeries were performed at Hospital Universitario Esperanza and Hospital NuestraSeñora del Pilar in Guatemala City from March 1999 to August 2008. The use of an MLc was considered to be successful if surgery was able to be completed without the need of changing to the use of an endotracheal tube. Results: The average age of our patients was 45 years, 88% (148) were female, the average size of the glands was 9.03 cms., 166 (99%) had a grade I/II Mallampati score, 119 (71%) had a benign diagnosis and 49 (29%) had cancer, 77 (46%) were submitted to a lobectomy, 85 (51%) had a total thyroidectomy and 6 (3%) had a radical neck resection. Thyroid surgery was successfully completed using aMLc in 95% of cases (159). In 9 patients (5%) the MLc was substituted with an endotracheal tube. After univariate and adjusted analysis age, sex, goiter size, Mallampati score, pathologic diagnosis and surgical procedure were not statistically associated with rate of dislodgement of classic laryngeal mask during thyroid surgery. Conclusions: Thyroid surgery is possible using aMLc. This is independent of goiter size, pathologic diagnosis, and the extent of the surgical procedure.

Thyroid autoimmunity in patients with hyperprolactinemia: an observational study / Autoimunidade tireoidiana em pacientes com hiperprolactinemia: um estudo observacional

Objective : To establish whether there is a relationship between hyperprolactinemia and primary thyroid disorders, focusing on patients with autoimmune features. Materials and methods : The medical records of 100 patients with hyperprolactinemia (HPRL) were retrospectively examined. Records of thyroid ultrasonography (USG), basal serum levels of thyroid stimulating hormone, circulating free thyroxine, free triiodothyronine, antithyroglobulin (anti-Tg), and antithyroperoxidase (anti-TPO) antibodies were analyzed. In 100 control subjects, matched by age and gender with HPRL patients, thyroid USG, thyroid function tests (TFTs), and autoantibody panel were obtained. Results : The median PRL in patients was 93 ng/mL (range: 37-470). Twenty-five patients (25%) and 22 controls (22%) had positive anti-Tg and/or anti-TPO titers (P = 0.739). The median serum PRL was 98 (37-470) ng/mL in patients with positive thyroid autoantibodies, and 92 (40-470) ng/mL in patients who were negative (P = 0.975). Among the individuals with autoantibody positivity TFTs abnormalities were more frequent in HPRL patients (60%, out of 25 patients, 14 with subclinical hypothyroidism and one with hyperthyroidism) than in controls (9.1%, out of 22 patients, 2 with subclinical hyperthyroidism) (P < 0.001). Twenty-seven patients with HPRL and 31 controls had goiter (27 vs. 31%, P = 0.437). Forty-six patients (46%) and 50 (50%) controls had one or more of the features of thyroid disorder, which were goiter, positive thyroid autoantibody, and thyroid function abnormality (P = 0.888). Conclusion : HPRL may be associated with more severe thyroid dysfunction in patients with thyroid autoimmunity. .

Objetivo : Verificar se existe uma relação entre a hiperprolactinemia e distúrbios primários da tireoide, focando em pacientes com características autoimunes. Materiais e métodos : Os prontuários de 100 pacientes com hiperprolactinemia (HPRL) foram examinados retrospectivamente. Foram analisados registros de ultrassonografia da tireoide (USG), níveis séricos basais de hormônio tireoestimulante, tiroxina livre, triiodotironina livre e anticorpos antitireoglobulina (anti-Tg) e antitireoperoxidase (anti-TPO). Foram obtidos de 100 controles, pareados por idade e sexo com pacientes com HPRL, USG, testes de função da tireoide (TFTs) e painel de autoanticorpos. Resultados : A média de PRL em pacientes foi de 93 ng/mL (variação: 37-470). Vinte e cinco pacientes (25%) e 22 controles (22%) foram positivos para títulos de anti-Tg e/ou anti-TPO (P = 0,739). A mediana de PRL sérica foi de 98 (37-470) ng/mL em pacientes positivos para autoanticorpos tiroidianos e 92 (40-470) ng/mL em pacientes negativos (P = 0,975). Entre os indivíduos positivos para autoanticorpos, as anormalidades da TFTs foram mais frequentes em pacientes HPRL (60%; de 25 pacientes, 14 com hipotireoidismo subclínico e um com hipertireoidismo) do que nos controles (9,1%; de 22 pacientes, 2 com hipertireoidismo subclínico) (P < 0,001). Vinte e sete pacientes com HPRL e 31 controles apresentavam bócio (27 contra 31%; P = 0,437). Quarenta e seis pacientes (46%) e 50 (50%) controles tiveram uma ou mais das características de problemas de tireoide, como bócio, autoanticorpos antitireoide e anormalidades da função tiroidiana (P = 0,888). Conclusão : A HPRL pode estar associada à disfunção da tireoide mais grave em pacientes com autoimunidade contra a tireoide. .

Prevalence of goiter and thyroid nodular disease in patients with class III obesity / Prevalência de bócio e doença nodular tireoidiana em pacientes com obesidade grau III

OBJECTIVES: To evaluate the prevalence of goiter and nodular disease in patients with class III obesity, and to correlate results with serum leptin levels and insulin resistance (IR) parameters. SUBJECTS AND METHODS: A cross-sectional study was performed to assess thyroid ultrasound (US) patterns, HOMA-IR, serum leptin, and TSH levels in obese patients and controls. RESULTS: Thyroid volume was positively correlated with body mass index (BMI) (r = 0.240, p = 0.039) and with HOMA-IR (r = 0.329; p < 0.01). Thyroid US patterns were similar between groups. However, when data from the male group was considered, greater thyroid volume was detected in the obese group compared with controls (10.8 vs. 8.5 cm³; p = 0.04). Also, nodules were more frequently detected (67% vs. 18%), as were nodules requiring FNAB (33.3% vs. 0%, p ≥ 0.05-0.09), in this group. CONCLUSION: Although IR did not correlate directly with the presence of nodules, the results support the hypothesis of a direct association between insulin resistance and thyroid volume.

OBJETIVOS: Avaliar a prevalência de bócio e doença nodular tireoidiana em pacientes com obesidade grau III e correlacionar os resultados com os níveis de leptina e parâmetros de resistência à ação da insulina (RI). SUJEITOS E MÉTODOS: Estudo seccional foi desenvolvido realizando ultrassonografia (US) tireoidiana e níveis séricos de HOMA-IR e TSH nos pacien­tes obesos e nos controles. RESULTADOS: Volume tireoidiano foi positivamente correlacionado com índice de massa corporal (IMC) (r = 0,240, p = 0,039) e com HOMA (r = 0,329; p < 0,01). Volume tireoidiano e prevalência de doença nodular tireoidiana foram similares entre os grupos. Quando avaliado o subgrupo masculino, maiores volumes tireoidianos foram detectados no grupo dos obesos comparados aos controles (10,8 vs. 8,5 cm³; p = 0,04), nódulos foram mais frequentes (67% vs. 18%), assim como nódulos com indicação de punção (33,3% vs. 0%, p ≥ 0,05-0,09). CONCLUSÃO: Embora RI não se correlacione diretamente com a presença de nódulos, os resultados suportam a hipótese da direta associação entre resistência à ação da insulina e volume tireoidiano.

Prenatal diagnosis and treatment perspective of fetal hypothyroidism with goiter

We describe two cases of fetal goiter in women with no history of thyroid disease. Diagnosis of fetal goiter during antenatal care was made by ultrasound and MRI. Congenital hypothyroidism was confirmed by fetal blood sampling that was treated with weekly intra-amniotic injections of L-thyroxin. One fetus was initially treated with four weekly intra-amniotic injections of 200 micro gms of L-thyroxin, later increased to 400 micro gms. The other fetus was treated with only three weekly intraamniotic injections of 400 micro gms of L-thyroxin. Therapeutic response was monitored by repeated ultrasound and MRI along with fetal blood sampling. At birth, none of the babies had goiter and were put on oral thyroxin. Post-natal studies were suggestive of congenital hypothyroidism due to dyshormogenesis. No abnormality was detected at follow-up. These cases highlight the role of intra-amniotic thyroxine in management of fetal hypothyroidism with goiter

Epidemiological Assessment of Goiter.

Research Question: 1. What is the magnitude of problem of Goiter? 2. What is the level of iodised salt consumed by school children at school & home? Objectives: 1. To find out incidence of Goiter. 2. To find out level of iodised salt consumed by school children at school & home. Study Design: Cross-sectional study. Settings: School & houseto- house survey of urban & rural area of Raichur district. Participant: School children & general population of both sexes. Sample size: 45173. Statistical analysis: Proportion & Chi-squared test. Results: Total population covered 45173 in five talukas. Males were 23463 & females 21730, adult population 16404, children more than 15 yrs were 28769 & school population was 24984. School boys were 14269 & girls 10715. Highest prevalence of goiter found in Raichur taluka i.e. 5.68% and lowest in Lingsur taluka i.e. 0.86%. Over all prevalence of Goiter among surveyed villages is found to be 3.19 % (1439 cases). Higher prevalence has been reported among females in age group of 10- 14 yrs 5.25% & 15-19 yrs 4.66% compared to other age groups of village population. School children in Raichur district revealed the prevalence of Goiter 3.66%. Conclusion: Prevalence of Goiter among surveyed villages is found to be 3.19 % (1439 cases), which is less compared to the National figures. The people are consuming the iodated salt and ban on non-iodated salt may be effectively implemented in study region.

Clinical and laboratory features of children and adolescents with congenital hypothyroidism due to dyshormonogenesis in southern Brazil / Características clínicas e laboratoriais de crianças e adolescentes com hipotireoidismo congênito devido a disormonogênese no sul do Brasil

OBJECTIVE: To characterize the phenotype of patients with congenital hypothyroidism (CH) due to dyshormonogenesis, and to hypothesize on the degree of genetic defect. SUBJECTS AND METHODS: Patients with dyshormonogenesis were subdivided into G1 (radioactive iodine uptake, RAIU > 15%; n = 62) and G2 (RAIU < 15%; n = 32). Thyroglobulin (TG) was measured in all patients; perchlorate discharge test (PDT) was performed in G1; and saliva-to-plasma radioiodine ratio (I- S/P) in G2. RESULTS: Levels of TSH, TT4, and FT4 before treatment and upon diagnosis confirmation were significantly different in both groups, but not between groups. In G1, 27 patients developed goiter; 17 had positive PDT (14%-71% discharge), 11 had TG < 2.5 ng/dL (one with high TSH), and one developed thyroid carcinoma. In G2, four patients developed goiter, and three had low I- S/P. CONCLUSION: These data suggest an iodide organification defect in 17 cases; an iodide transport defect (NIS defect) in three, probable TSH resistance in 10, and a TG synthesis defect in two cases.

OBJETIVO: Caracterizar o fenótipo de pacientes com hipotireoidismo congênito (HC) por disormonogênese e sugerir o nível do defeito genético. SUJEITOS E MÉTODOS: Pacientes com disormonogênese foram subdivididos em G1 (captação de 131I > 15%; n = 62) e G2 (captação < 15%; n = 32). Tireoglobulina (TG) foi dosada em todos, teste de descarga do perclorato (TDP) foi realizado no G1 e relação iodo salivar/sérico (I- S/P), no G2. RESULTADOS: Os valores de TSH, T4T e T4L pré-tratamento e na confirmação do diagnóstico foram significativamente diferentes em ambos os grupos (p < 0,01), mas não entre eles. No G1, 27 pacientes desenvolveram bócio; TDP foi positivo em 17 (descarga de 14%-71%); 11 tiveram TG < 2,5 ng/dL (um com TSH elevado) e um desenvolveu carcinoma de tireoide. No G2, quatro pacientes desenvolveram bócio e três apresentaram baixa I- S/P. CONCLUSÃO: Esses dados sugerem defeito na organificação do iodeto em 17 casos; defeito no transporte do iodeto (defeito na NIS) em três, provável resistência ao TSH em 10 e defeito na síntese de TG em dois.

Surgical management of retrosternal goiter: local experience at a university hospital

Retrosternal goiter [RSG] is a term that has been used to describe a goiter that extends beyond the thoracic inlet. Surgery plays an important role in the treatment of these patients, but whether all or selected patients with RSG should undergo this operation remains controversial. Our aim is to look into the demographics, presentation, and treatment of patients with RSG and essentially to determine the role of surgery in its treatment. Retrospective study, teaching hospital-based. Retrospective analysis of 537 thyroidectomies performed at King Khalid University Hospital between 2003 and 2010. The twenty-six patients with RSG were analyzed further, with regard to demographics, presentation, indications, and outcome of surgical treatment. Statistical analysis was performed, where age was expressed as mean and range, and other variables were presented as numbers and percentage. There were 26 patients [4.8%] with RSG out of 537 thyroidectomies, who underwent an operation for removal of RSGs, in a seven-year period. The most common presentation was dyspnea [34.6%] and the surgical procedure predominantly used was total thyroidectomy. The RSGs were removed by collar incision in 96% of the cases. The final histological diagnosis revealed malignancy in 26.9% of the thyroid specimens. There was no mortality and minor complications occurred in nine patients. The presence of an RSG is an indication for surgery owing to the lack of effective medical treatment, the higher incidence of symptoms related to compression, low surgical morbidity, and the risk of malignancy

High prevalence of thyroid disorders in relatives of patients with familial papillary thyroid cancer / Elevada prevalencia de alteraciones tiroideas en familiares de pacientes con diagnóstico de carcinoma papilar familiar

In the familial form of papillary thyroid cancer (PTC), two or more members of the same family have to be affected with PTC. Prevalence is around 5% of all PTC. We performed a clinical analysis in 79 relatives of 16 patients of 7 unrelated kindred with the diagnosis of familial papillary thyroid carcinoma (FPTC). The results were compared with a control group. Thyroid palpation and TSH and TPO-Ab assessment was carried out in the relatives without a diagnosed PTC. Additionally, molecular analysis was performed in the sixteen affected patients. Clinical screening of the 79 family members showed the presence of goiter in 22/79 (29 %). This frequency was much higher than that observed in the control group (8.7%), p < 0.001. Hypothyroidism was found in 4 of the relatives (5%) vs. 2.5% observed in the control group, p < 0.01, and anti-thyroid antibodies (TPO-Ab) were positive in 14% of the relative's group vs. 10 % in the control group, (p = NS). In the molecular analysis, only a protooncogene TRK rearrangement was observed in family # 6. In conclusion, we found a higher incidence of goiter and hypothyroidism in the relatives of patients with FPTC. Nevertheless, TPO-Ab frequency was not different. No molecular abnormalities were indicative of a specific pattern in this subset of patients with FPTC.

En la forma familiar del carcinoma papilar de tiroides (CPT), dos o más miembros de la misma familia deben presentar CPT. Esta entidad ocurre en aproximadamente el 5% de todos los CPT. En este estudio, realizamos una evaluación de 79 familiares de 16 pacientes con diagnóstico de carcinoma papilar familiar (CPF) provenientes de 7 familias diferentes. Los resultados se compararon con los hallados en un grupo control. Se realizó palpación tiroidea y medición de TSH y anticuerpos anti-tiroperoxidasa (TPO-Ab) en todos los familiares. Además, se llevó a cabo el análisis molecular en los 16 sujetos que presentaban el diagnóstico de CPF. La evaluación de los 79 familiares de estos pacientes demostró la presencia de bocio en 22/79 (29%). Esta frecuencia fue mucho mayor que la observada en el grupo control (8.7%), p < 0.001. Se diagnosticó hipotirodismo en 4 familiares (5%) vs. 2.5%, observado en el grupo control, p < 0.01, y los TPO-Ab fueron positivos en 14% de los familiares vs. 10% del grupo control, (p = ns). En el análisis molecular, solamente se halló un rearreglo del protoncogen TRK en una de las 7 familias con CPF. En conclusión, hallamos una elevada prevalencia de bocio e hipotiroidismo en los familiares de pacientes con CPT. Sin embargo, la frecuencia de autoinmunidad no fue diferente. No se hallaron alteraciones moleculares distintivas en estos pacientes con CPF.

Solitary thyroid nodule, frequency of malignancy at combined military hospital Rawalpindi

To determine frequency of malignancy in solitary thyroid nodule. Case-series study. The study was conducted at Department of Surgery, Combined Military Hospital Rawalpindi, from April 2002 till April 2003. Sixty patients with clinical solitary thyroid nodule fulfilled the selection criteria and were included in the study. Thyroid function tests, ultrasonography and thyroid scanning was done. Finally FNAC and histopathology were done in all the operated cases and record was evaluated. Out of 60 cases studied, 8 [13.33%] were found to have malignant lesions. The remaining 52 [86.67%] cases had benign pathology. Male patients with solitary thyroid nodule showed a higher incidence of malignancy 17.65% as compared to females 11.63%, Maximum malignant cases [50%] were found between the ages of 31 to 40 years. Papillary carcinoma was the most common malignancy [50%] found in our study. The incidence of malignancy in solitary thyroid nodule is quite high [13.33%]. So people should be educated to attend thyroid clinics for early diagnosis and adequate treatment

Aspectos patogênicos e clínicos do bócio multinodular / Pathogenic and clinical aspects of multinodular goiter

O bócio multinodular (BMN) é definido como um aumento da glândula tireóide secundário à proliferação multifocal de tireócitos e caracteriza-se pela heterogeneidade no crescimento e função das células foliculares. O BMN é considerado uma neoplasia benigna da tireóide. É uma doença comum, com aumento da prevalência em áreas com deficiência de iodo, sendo este o principal fator etiológico ambiental. A patogênese desta disfunção tireoidiana ainda não está inteiramente elucidada. Nesta revisão serão abordados os principais mecanismos envolvidos na patogênese, seguidos das implicações clínicas dessa patologia.

Multinodular goiter (MNG) is defined as an enlargement of the thyroid gland that is characterized by heterogeneity in growth and function of thyroid follicular cells. MNG is now considered a true thyroid neoplasm. It is a common disease, with higher prevalences in iodine deficiency areas. Iodine deficiency is the main environmental etiologic factor for MNG. The pathogenesis of multinodular goiter is not yet fully clarified. The purpose of this review is to summarize the current knowledge of MNG with respect to the pathology, etiologic and clinical characteristics.

Trastornos tiroideos en pacientes con falla ovárica prematura / Thyroid disorders in patients with premature ovarian failure

La falla ovárica prematura (FOP), también llamada menopausia precoz, se define como la pérdida de la función cíclica de los ovarios antes de los 40 años de edad y después de la pubertad. Se ha reportado anormalidades endocrinas y autoinmunes asociadas con la FOP y se ha sugerido que las enfermedades tiroideas son comunes. Sesenta y dos mujeres con FOP fueron estudiadas para determinar la frecuencia de trastornos tiroideos, ya que no hay estudios sobre esta asociación en esta región geográfica. La evaluación incluyó historia clínica y examen físico, medición de tiroestimulina (TSH)...
