    Full Text Available La gravedad de la infección respiratoria aguda (IRA es mayor en países en desarrollo, sobre todo entre grupos social y económicamente pobres. Las neumonías virales son las más comunes, especialmente en niños. Con el fin de medir algunos factores asociados con formas graves de infección respiratoria baja realizamos un estudio de casos y controles prospectivo y de base hospitalaria en Bogotá entre noviembre de 2000 y agosto de 2001. Los casos fueron niños entre 2 meses y 5 años que llenaban los criterios de la OMS para IRA grave o muy grave. Los controles eran niños con IRA en el mismo rango de edad, que consultaban al mismo hospital y que no presentaban tirajes. Se estudiaron 638 niños entre los 2 meses y los 5 años de edad (277 casos y 361 controles. Los factores más importantes fueron: vivienda en préstamo (OR=2,7; IC95%: 1,06-7,07, compartir la cama (OR=1,88; IC95%: 1,0-3,7, más de 9 personas en la misma casa (OR=1,82; IC95%: 1,0-3,51 y fumadores en la vivienda (OR=1,4; IC95%: 1,0-2,05. Se tomaron 114 muestras nasofaríngeas (niños con 3 días de haber iniciado síntomas y se obtuvieron virus en 98 de ellas, y se identificó el virus sincitial respiratorio en 41,8%, virus influenza A en 3,1% y virus influenza B en 1%. El 100% de los aislamientos positivos para influenza A y B fueron enviados al CDC en Atlanta, donde fueron clasificados como influenza A/PANAMA/2007/99-like e influenza B/SICHUAN/379/99-like, respectivamente.

    2008-12-01

    Full Text Available La amiloidosis es una entidad clínica que se produce a consecuencia del depósito a nivel extracelular de un material proteico amorfo, causando una desorganización de la arquitectura normal de múltiples órganos y tejidos y, por tanto, una alteración funcional de los mismos. La amiloidosis secundaria es una complicación infrecuente pero muy grave que aparece en el contexto de neoplasias, enfermedades infecciosas e inflamatorias de curso crónico, como es el caso de la enfermedad inflamatoria intestinal, principalmente enfermedad de Crohn, ensombreciendo el pronóstico de estos pacientes. A continuación presentamos dos casos clínicos correspondientes a dos pacientes con enfermedad de Crohn que desarrollaron amiloidosis secundaria.Amyloidosis is a clinical entity that results from the deposition of an extracellular protein material that causes disruption in the normal architecture of multiple organs and tissues, and impairs their function. Secondary amyloidosis is a rare but serious complication that may worsen the prognosis of patients with cancer, infection or chronic inflammatory disease, including inflammatory bowel disease, particularly Crohn's disease. We report two cases of Crohn's disease associated with secondary amyloidosis.

    2012-01-01

    El Mal Agudo de Montaña (MAM) es un conjunto de síntomas inespecíficos padecidos por sujetos que ascienden rápidamente desde baja a alta altura sin adecuada aclimatación. Usualmente es autolimitado, pero las formas graves (edema pulmonar y cerebral) pueden causar la muerte. La hipoxemia exagerada en reposo está relacionada con el desarrollo de MAM pero su valor predictivo es limitado. Dado que el ejercicio en altura se acompaña de mayor hipoxemia y síntomas, postulamos el valor predictivo de un simple test de ejercicio para pronosticar MAM grave. Se estudió el valor predictivo de la saturación de oxígeno en reposo y ejercicio submáximo a 2 700m y 4 300m en 63 sujetos que ascendían al cerro Aconcagua (6 962m). Se consideró desaturación de oxígeno con ejercicio a una disminución >=5% respecto al reposo. Se utilizó la escala de Lake-Louise para establecer la presencia de MAM grave. 6 sujetos presentaron MAM grave (9.5%) y requirieron evacuación. La saturación de oxígeno en reposo a 2 700m no fue significativa para clasificar sujetos que luego desarrollaron MAM grave. Por el contrario, la asociación de desaturación durante el ejercicio a 2 700m más la saturación inapropiada en reposo a 4 300m fue significativa para clasificar a los sujetos que desarrollaron MAM grave con un valor predictivo positivo de 80% y un valor predictivo negativo del 97%. Nuestros resultados son relevantes para el montañismo y sugieren la adición de un simple test de ejercicio en la predicción del MAM grave. PMID:20228017

  6. Grado de alfabetización informacional del profesorado de Secundaria en España: Creencias y autopercepciones

    Full Text Available La alfabetización informacional es una de las dimensiones de la competencia digital y, como tal, debe ser tenida muy en cuenta dentro de las competencias asumibles por cualquier persona en nuestros días, inmersa en la sociedad de la información y la comunicación, pero más concretamente por el profesorado de Educación Secundaria dada la gran importancia que tiene esta etapa en la formación de los alumnos. En este estudio hemos querido conocer cuál es el grado de alfabetización informacional del profesorado de Secundaria del estado español. Para ello hemos construido y aplicado un cuestionario (n=2.656. En dicho instrumento hemos sometido al profesorado a dos partes bien diferenciadas, una con cuestiones de creencia y autopercepción sobre los indicadores de la alfabetización informacional, y por otra, con cuestiones de situación, casos prácticos en los que el profesorado ha tenido que poner en práctica las habilidades y destrezas que tiene sobre la alfabetización informacional. Los resultados obtenidos confirman que las creencias del profesorado de Educación Secundaria dan valores bastante elevados pero también nos muestran que si bien el grado de alfabetización informacional del profesorado consigue el aprobado, hay ciertos aspectos de los indicadores relativos a la evaluación, gestión y transformación de la información donde los docentes tienen graves carencias. Todo ello pone de manifiesto la necesidad de plantear un plan formativo en alfabetización informacional del profesorado de Educación Secundaria de España.

    Full Text Available El objetivo general del presente estudio ha sido evaluar los patrones de uso del teléfono móvil en población adolescente escolarizada en centros de Educación Secundaria. De modo adicional, hemos evaluado correlatos psicológicos (ansiedad, depresión y conductuales y asociación con rendimiento escolar. Para la realización del estudio se contó con 528 alumnos, con edades entre los 12 y los 19 años, pertenecientes a cinco centros educativos, cuatro públicos y uno concertado. Los instrumentos utilizados fueron el Cuestionario de Evaluación de la Depresión de Beck (BDI, el Cuestionario de Evaluación de la Ansiedad de Beck (BAI, las escalas de baja autoestima y problemas escolares del Cuestionario de Personalidad MMPI-A, y el Cuestionario para evaluar el uso excesivo del Móvil (COS. Los resultados indican que un porcentaje significativo de estudiantes que abusan del teléfono móvil muestran sintomatología depresiva y ansiógena y baja autoestima. Un 14.8% de los participantes obtiene puntuaciones que les sitúa en un rango de problemas escolares elevado o alto, a su vez vinculado con un uso patológico del teléfono móvil.

    2012-02-01

    Full Text Available En la actualidad existe un amplio interés por el valor del paisaje como una alternativa de análisis ambiental, sin embargo, esta aproximación ha sido poco utilizada en los ecosistemas de México. El objetivo de este estudio fue determinar el valor del paisaje en la selva baja caducifolia (SBC de la cuenca baja del río Papagayo, Guerrero, México. Se realizó una clasificación jerárquica de paisajes y se aplicó un índice de valor del paisaje basado en cuatro indicadores: sensibilidad de laderas, fragmentación, calidad visual y significado social. Los resultados indican que el área está constituida por tres sistemas de paisajes –montañas, lomeríos y llanura aluvial– definidos por cambios morfo-litológicos y bioclimáticos; 17 subsistemas de paisajes y 16 paisajes elementales, definidos por los tipos de vegetación, usos de suelo y niveles de perturbación. El valor del paisaje fue heterogéneo, aunque tiende a ser mayor en los subsistemas montañosos de selvas y bosques, debido a que son más inaccesibles, por lo que el significado social y los niveles de perturbación y fragmentación se reducen. En contraste, los subsistemas de lomeríos con selva baja caducifolia tienen alto significado social debido a la cercanía y accesibilidad, lo cual favorece la intensificación de los usos del suelo, el incremento de la fragmentación y la caída de la calidad visual y del valor natural del paisaje. Si bien, la vegetación secundaria de la SBC (acahual ha sido valorada por su importancia en los mecanismos de regeneración de las selvas, en este caso obtuvo un valor reducido debido a la intensidad en el manejo de recursos, tanto en el pastoreo, como en la extracción de leña y la producción de carbón. El método implementado en este estudio permite sintetizar el balance entre la degradación ambiental y los caracteres de la apropiación cultural del paisaje en escalas geográficas amplias.

  12. Miastenia grave y miastenia grave ocular

    Rosa María Naranjo Fernández

    Full Text Available La miastenia grave es una enfermedad caracterizada por debilidad y fatiga de los músculos voluntarios debido a una trasmisión anómala a nivel de la unión neuromuscular. La prevalencia es aproximadamente de 5 casos/100 000 personas. La miastenia grave puede ser bulbar, ocular o generalizada.Existen formas clínicas en la infancia como son la miastenia neonatal transitoria, la miastenia congénita y la miastenia juvenil. Los músculos oculares, faciales y bulbares son los más frecuentes afectados por la enfermedad. Cuando los síntomas se limitan a la musculatura cercana al ojo se denomina miastenia grave ocular. Una vez el oftalmólogo diagnostica o sospecha la miastenia grave, un neurólogo generalmente dirige la comprobación y tratamiento. El papel del oftalmólogo continúa siendo importante, además de chequear la motilidad y disfunción palpebral y proporcionar el alivio sintomático para estos desórdenes, debe estar alerta a la posibilidad de ambliopía.

  20. Graves' disease following subacute thyroiditis.

    Science.gov (United States)

    Nakano, Yoshishige; Kurihara, Hideo; Sasaki, Jun

    2011-12-01

    Subacute thyroiditis is a painful, inflammatory disease frequently accompanied with fever. It is suspected to be a viral infectious disease, while Graves' disease is an autoimmune disease. Thus, there appears to be no etiological relationship between the two diseases. A total of 25,267 thyroid disease patients made their first visits to our thyroid clinic during a period of 24 years between 1985 and 2008. Among them, subacute thyroiditis and Graves' disease accounted for 918 patients (3.6%) and 4,617 patients (18.2%), respectively. We have encountered 7 patients (one male and six female) with subacute thyroiditis followed by Graves' disease in this period (0.15% of the 4,617 patients with Graves' disease and 0.76% of the 918 patients with subacute thyroiditis). The age ranges were 40~66 years (mean 48.7 years) at the onset of subacute thyroiditis. The intervals between the onsets of subacute thyroiditis and Graves' disease were 1~8 months (mean 4.7 months). Because Graves' disease was preceded by subacute thyroiditis, the signs and symptoms of both diseases were evident together in the intervening period. The diagnosis of Graves' disease in those patients is always difficult because of atypical signs and symptoms and an unclear onset time. The causes of the Graves'disease that followed subacute thyroiditis are still unknown. However, the inflammatory nature of subacute thyroiditis may lead to the activation of the autoimmune response in susceptible subjects, resulting in the onset of Graves' disease. Graves' disease should be suspected when a high blood level of thyroid hormone persists after subacute thyroiditis.

  3. Thyroid surgery for Graves' disease and Graves' ophthalmopathy.

    Graves' disease is an autoimmune disease caused by the production of auto-antibodies against the thyroid-stimulating hormone receptor, which stimulates follicular cell production of thyroid hormone. It is the commonest cause of hyperthyroidism and may cause considerable morbidity with increased risk of cardiovascular and respiratory adverse events. Five per cent of people with Graves' disease develop moderate to severe Graves' ophthalmopathy. Thyroid surgery for Graves' disease commonly falls into one of three categories: 1) total thyroidectomy, which aims to achieve complete macroscopic removal of thyroid tissue; 2) bilateral subtotal thyroidectomy, in which bilateral thyroid remnants are left; and 3) unilateral total and contralateral subtotal thyroidectomy, or the Dunhill procedure. Recent American Thyroid Association guidelines on treatment of Graves' hyperthyroidism emphasised the role of surgery as one of the first-line treatments. Total thyroidectomy removes target tissue for the thyroid-stimulating hormone receptor antibody. It controls hyperthyroidism at the cost of lifelong thyroxine replacement. Subtotal thyroidectomy leaves a thyroid remnant and may be less likely to lead to complications, however a higher rate of recurrent hyperthyroidism is expected and revision surgery would be challenging. The choice of the thyroidectomy technique is currently largely a matter of surgeon preference, and a systematic review of the evidence base is required to determine which option offers the best outcomes for patients. To assess the optimal surgical technique for Graves' disease and Graves' ophthalmopathy. We searched the Cochrane Library, MEDLINE and PubMed, EMBASE, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). The date of the last search was June 2015 for all databases. We did not apply any language restrictions. Only randomised controlled trials (RCTs) involving participants with a diagnosis

  5. Hashimoto's thyroiditis following Graves' disease.

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment.

    Graves' disease is a common cause of thyrotoxicosis. Treatment options include anti-thyroid medications or definitive therapy: thyroidectomy or radioactive iodine (I(131) ). Traditionally, I(131) has been the preferred definitive treatment for Graves' disease in New Zealand. Reports of concomitant thyroid cancer occurring in up to 17% of Graves' patients suggest surgery, if performed with low morbidity, may be the preferred option. The aim of this study was to determine the rate of thyroid cancer and surgical outcomes in a New Zealand cohort of patients undergoing thyroidectomy for Graves' disease. This study is a retrospective review of Waikato region patients undergoing thyroid surgery for Graves' disease during the 10-year period prior to 1 December 2011. A total of 833 patients underwent thyroid surgery. Of these, 117 were for Graves' disease. Total thyroidectomy was performed in 82, near-total in 33 and subtotal in 2 patients. Recurrent thyrotoxicosis developed in one subtotal patient requiring I(131) therapy. There were two cases of permanent hypoparathyroidism and one of permanent recurrent laryngeal nerve palsy. Eight patients (6.8%) had thyroid cancer detected, none of whom had overt nodal disease. Five were papillary microcarcinomas (one of which was multifocal), two were papillary carcinomas (11 mm and 15 mm) and one was a minimally invasive follicular carcinoma. Thyroid cancer was identified in approximately 7% of patients undergoing surgery for Graves' disease. A low complication rate (<2%) of permanent hypoparathyroidism and nerve injury (<1%) supports surgery being a safe alternative to I(131) especially for patients with young children, ophthalmopathy or compressive symptoms. © 2012 The Authors.

    Full Text Available En el marco de una investigación sobre las relaciones de humillación entre estudiantes desde la perspectiva de alumnos de educación secundaria se indagaron los modos en que los actores escolares abordan estas modalidades de vinculación. Se analizaron, por un lado, las maneras de responder a las humillaciones por parte de los alumnos que son humillados y, por otro, las intervenciones que realiza la escuela (docentes, directivos, preceptores. Los datos se obtuvieron a partir de entrevistas en profundidad a estudiantes de dos escuelas de la provincia de Buenos Aires, Argentina. Los resultados revelan que existe por parte de los estudiantes que sufren estas prácticas una escasa demanda de la mediación de los docentes y directivos; lo cual se complementa con una baja intervención de las autoridades de la escuela ante estas formas de sociabilidad. De este modo, las maneras de actuar de los diversos actores componen un escenario que dificulta un abordaje institucional que permita dar soluciones a esta problemática.

    Graves' disease is the most common cause of hyperthyroidism in the developed world. It is caused by an immune defect in genetically susceptible individuals in whom the production of unique antibodies results in thyroid hormone excess and glandular hyperplasia. When unrecognized, Graves' disease impacts negatively on quality of life and poses serious risks of psychosis, tachyarrhythmia and cardiac failure. Beyond the thyroid, Graves' disease has diverse soft-tissue effects that reflect its systemic autoimmune nature. Thyroid eye disease is the most common of these manifestations and is important to recognise given its risk to vision and potential to deteriorate in response to radioactive iodine ablation. In this review we discuss the investigation and management of Graves' disease, the recent controversy regarding the hepatotoxicity of propylthiouracil and the emergence of novel small-molecule thyroid-stimulating hormone (TSH) receptor ligands as potential targets in the treatment of Graves' disease.

    Full Text Available La osteoporosis puede y debe prevenirse, diagnosticarse y tratarse, preferentemente antes de que aparezca la fractura por fragilidad. El objetivo fue analizar las intervenciones de prevención primaria y secundaria llevadas a cabo en las personas que sufrieron fractura de cadera por fragilidad en 2014 en el sector sanitario de Teruel. Método: Estudio descriptivo transversal. Variables analizadas: sexo, edad, zona básica de salud, residencia, situación funcional basal, antecedente de osteoporosis, fractura de fémur o vertebral, pérdida de estatura, utilización de FRAX, tratamiento al alta, exitus y su causa. Se empleó t- Student y ANOVA para variables cuantitativas por categorías y regresión para relaciones lineales. Resultados: Se incluyó a 148 personas, de las cuales 123 eran mujeres, con una mediana de edad de 87 años, 27,4% tenían dependencia grave o total para las actividades de la vida diaria, 33% estaban institucionalizados.

En este trabajo se analizaron las emociones de 38 futuros profesores de secundaria que cursan el Máster Universitario en Formación del Profesorado en Educación Secundaria de la Universidad de Extremadura en tres especialidades: Biología y Geología, Matemáticas, y Física y Química. Se utilizó un cuestionario para estudiar sus emociones frente a las distintas asignaturas de ciencias y matemáticas de secundaria, como futuros docentes y en su etapa de estudiantes. Los resultados indican que en el recuerdo de sus emociones como alumnos de secundaria se apreciaron diferencias en las distintas asignaturas según las especialidades del máster. En general los futuros docentes mostraron emociones positivas frente a las asignaturas que se corresponden con su especialidad y negativas frente al resto, salvo para la Biología y la Física. Para la Biología todos muestran emociones positivas. En relación a las emociones que expresaron como futuros docentes, éstas eran siempre positivas ante asignaturas de su especialidad y negativas frente al resto. Sin embargo ante la Física los futuros profesores de la especialidad de Física y Química mostraron casi en la misma medida emociones positivas y negativas durante su etapa de secundaria y como futuros docentes. Parece ser que la falta de especialización del profesorado está relacionada no sólo con los conocimientos específicos sino también con las emociones. Por este motivo es necesario que en su formación se les dé a los futuros docentes la oportunidad de reflexionar sobre las experiencias educativas que han generado emociones positivas o negativas y de cómo estas emociones pueden influir en la enseñanza-aprendizaje de la ciencia.

    2003-01-01

    This brief review describes the history of Graves' disease, starting with the original descriptions by Parry, Graves and von Basedow. The true aetiology of the disorder was uncovered in the 1950s and 1960s, based on the search for a novel thyroid stimulator which turned out to be an immunoglobulin G autoantibody. Assays for these thyroid stimulatory antibodies have been continually refined and their epitopes on the thyroid stimulating hormone receptor are increasingly well characterized. We also understand far more about the genetic and environmental susceptibility factors that predispose to disease, and even thyroid-associated ophthalmopathy has now been better defined as primarily a T-cell-mediated disease resulting from cytokine stimulation of orbital fibroblasts. These advances should improve treatment options for Graves' disease in the foreseeable future.

We followed up 158 Graves' hyperthyroid patients treated with radioiodine of which 49 had Grave's' ophthalmopathy during presentation in Nuclear Medicine Centre, Khulna during the period from 1995 to 2000. The aim of our study is to see the effect of radioiodine in Graves' ophthalmopathy. All the patients received radioiodine at fixed dose regime ranged from 7 mCi to 12 mCi. The duration of follow up was at least 12 months Graves' ophthalmopathy patients, 4 (4/49 i.e., 8.2%) showed exaggeration of ophthalmopathy and the rest (45/49 i.e., 91.8%) remained unchanged. None of ophthalmopathy developed among any of Graves' hyperthyroid or disappeared after radioiodine treatment during follow up period. From the study we concluded that eye changes in Graves' hyperthyroidism remain unchanged or exaggerated after radioiodine therapy and needs ophthalmologist care.(author)

    To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

    Full Text Available La Educación Secundaria ha estado en el centro del desarrollo de las políticas sociales y el sistema educativo en Finlandia durante las últimas tres décadas. Después de crear, en los años 70, una escuela comprensiva que dura nueve años y es igual para todos los alumnos, los objetivos de la política educativa han sido siempre que todos los que dejan la escuela básica puedan tener acceso a la educación superior que elijan. Hoy en día, el sistema educativo finlandés está considerado como un estándar internacional de la buena calidad, junto con su condición de equidad y acceso a todo el sistema. En este artículo, analizo el doble reto -o sea, calidad de y acceso a la educación secundaria- a través de tres dimensiones: la tasa de transición de la Educación Secundaria Básica a la Educación Secundaria Superior, tasas de finalización de la Educación Secundaria y el aprendizaje de los alumnos. Luego, argumento que Finlandia ha sido capaz de crear un sistema de Educación Secundaria que funciona bien a un coste razonable, porque ha utilizado estrategias de reforma educativa basadas en (1 una visión a largo plazo de una buena Educación Secundaria para todos, (2 mejorar la calidad de la Educación Primaria para todos los niños, (3 diseñar un sistema de intervención temprana y asesoramiento y consejo educativo en los centros educativos de Primaria y Secundaria, (4 ayudar a todos los alumnos a tener éxito en la transición de Primaria a Secundaria y crear caminos de segundas oportunidades para incrementar las tasas de éxito, y (5 promover la construcción de la capacidad lateral en la que las escuelas y los municipios aprenden unos de otros. La experiencia en Finlandia sugiere que mejorar la calidad de la Educación Secundaria requiere políticas sostenibles y liderazgo, cultivando profesionalidad y confianza en todo el sistema educativo, y acercamientos inteligentes al currículum y a la responsabilidad.

    Full Text Available Princely graves of the Iron Age represent a particular phenomenon in archaeology, which is constantly the subject of interest. They are usually dated to the end of the 6th and the beginning of the 5th century. The author discusses the chronology of princely graves in the Central Balkans and analyses their appearance in each part of this territory: on the Glasinac plateau, in Serbia, Kosovo and Metohija, Montenegro, North Albania and Nordwest Bulgaria. He concludes that they date from the middle of the 7th to the middle of the 4th century, depending on the cultural and socio-economic situation in the respective area. In the middle of the 7th century princely graves in the true sense of the word were known only on the Glasinac plateau, in the Ilijak necropolis. At the end of the 7th and in the beginning of the 6th century they still appear on Glasinac, though in greater number and in various parts of the plateau. In northwest Bulgaria a grave dating to the second half of the 7th century was found, which would, according to grave goods, correspond to the Glasinac princely graves. On the other hand, there are no princely graves in Serbia and north Albania from that time but some outstanding warrior graves are known, belonging possibly to the chiefs of smaller warlike bands, whose power was limited. Princely graves from Arareva gromila on Glasinac, Pilatovići by Požega and Lisijevo Polje by Berane date to the beginning of the second half of the 6th century, and according to their characteristics represent princes, whose power and wealth were considerable and known to the neighbours. Culmination of the rise of the princes in this region was demonstrated by the graves from Novi Pazar, Atenica, and Pećka banja, which date to the end of the 6th and the first quarter of the 5th century. Some decades later there are several rich graves, e.g. the recently discovered grave from Velika Krsna, which could belong to a prince, but can not be compared with the

    Objective: To analyze the correlation between the therapeutic effect of Graves' hyperthyroidism and the outcomes of Graves' ophthalmopathy after 131 I therapy, and to explore the effect of 131 I treatment on turnout of Graves' ophthalmopathy. Methods: Six hundreds and fifty-two patients of Graves' disease accompanied with Graves' ophthalmopathy, received one-time 131 I treatment according to routine procedure. We recorded exophthalmometer readings, the signs and symptoms of eyes before therapy. Regular follow-up and appraisal of curative effect were carried out. Results: At least six months after 131 I therapy, the effective rate of Graves' hyperthyroidism and Graves' ophthalmopathy were 94.3% and 73.3% respectively. The total effective rate of hyperthyroidism with ophthalmopathy was 71.2%. There was a significant correlation between the prognosis of Graves' ophthalmopathy and therapeutic efficacy of hyperthyroidism (r=0.302, P 131 I therapy (χ 2 =0.296, P>0.05). Conclusions: The key to treat Graves' ophthalmopathy is the cure of Graves' hyperthyroidism through 131 I therapy. The timely diagnosis and replacement treatment of hypothyroidism can effectively avoid the aggravation of Graves' ophthalmopathy after 131 I therapy. (authors)

    The aim of the study was to determine the blood serum sulfated glycosaminoglycans (GAGs) and hyaluronic acid (HA) concentration of Graves' disease patients before treatment and after attainment of the euthyroid state. The study was carried out on the blood serum obtained from 17 patients with newly recognised Graves' disease and from the same patients after attainment of the euthyroid state. Graves' patients had not any clinical symptoms neither of ophthalmopathy nor pretibial myxedema. GAGs were isolated from the blood serum by the multistage extraction and purification using papaine hydrolysis, alkali elimination, as well as cetylpyridium chloride binding. Total amount of GAGs was quantified by the hexuronic acids assay. HA content in obtained GAGs sample was evaluated by the ELISA method. Increased serum concentration of sulfated GAGs in non-treated Graves' disease patients was found. Similarly, serum HA level in untreated patients was significantly elevated. The attainment of euthyroid state was accompanied by the decreased serum sulfated GAGs level and by normalization of serum HA concentration. In conclusion, the results obtained demonstrate that the alterations of GAGs metabolism connected with Graves' disease can lead to systemic changes of the extracellular matrix properties.

    The report describes a woman with primary antiphospholipid antibody syndrome complicated with Grave's disease. Developing symptoms included a small cutaneous nodule on her finger and subsequently ecchymotic purpura on the cheeks, ears, buttocks and lower legs. Histological examinations showed thrombosed vessels in the dermis without or with hemorrhage, respectively. Laboratory investigation revealed positive lupus anticoagulant and immunogenic hyperthyroidism due to Grave's disease. There is a close relationship between the cutaneous manifestation of antiphospholipid antibody syndrome and the activities of Grave's disease and a possible link of antiphospholipid antibody syndrome with Grave's disease was suggested both by the etiology of the disease as well as the disease activity.

Pada penelitian ini dilakukan analisa respon seismik Steel Slit Damper (SSD pada portal baja 1 lantai yang menerima beban lateral berupa beban gempa, dengan membandingkan portal baja konvensional, portal baja inverted-v, dan portal baja dengan SSD. Hasil analisa menunjukkan bahwa gaya geser, gaya normal, dan momen yang dihasikan portal dengan SSD lebih kecil hingga 80,49% dari gaya-gaya yang dihasilkan portal konvensional, tetapi gaya-gaya tersebut masih lebih besar daripada yang dihasilkan portal inverted-V. Portal dengan SSD dapat memperkecil simpangan sebesar 94,12% pada portal konvensional dan sebesar 33,33% pada portal bracing inverted-v. Hasil penelitian juga menunjukkan bahwa portal SSD memiliki daktilitas 105,85% lebih tinggi dari portal konvensional dan 298,67% lebih tinggi dari portal bracing inverted-v

    It is still debated which treatment modality for Graves' hyperthyroidism (GH) is most appropriate when Graves' orbitopathy (GO) is present.

    It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as experience tetany postoperatively than patients undergoing total thyroidectomy for other indications. This suggests that

    The incidence of thyroid carcinoma is increasing worldwide. Graves' disease is the most common hyperthyroid disease. Studies have suggested an increased risk of thyroid malignancy in Graves' disease: there has not yet been a meta-analysis to allow quantitative comparison. The purpose of this study was to determine the risk of thyroid carcinoma in Graves' disease, and to gather information on the histological subtypes of carcinoma and the co-existence of thyroid nodules. Several databases and article reference lists were searched. Inclusion criteria included appropriate diagnostic criteria for thyroid conditions and a diagnoses of carcinoma based on histology. 33 studies were selected, all reporting on surgically-resected specimens. The event rate of thyroid carcinoma in Graves' disease was 0.07 (95% CI 0.04 to 0.12). There was no data to allow comparison with patients without hyperthyroid diseases. There was no increase in the odds of developing carcinoma in Graves' disease compared to toxic multinodular goitre and toxic uninodular goitre. 88% of thyroid carcinomas in Graves' disease were papillary, with solitary papillary micro-carcinoma (diameter 10 mm or less) comprising 23% of all detected thyroid carcinomas. Patients with Graves' disease and co-existing thyroid nodules were almost 5 times more likely to be diagnosed with thyroid carcinoma than those without nodules. Thyroid malignancy in Graves' disease requiring surgical treatment should be considered as likely as in other hyperthyroid diseases needing surgical treatment. Clinicians should consider screening selected patients with Graves' disease for nodules whilst being aware of potentially over-diagnosing papillary micro-carcinoma. Crown Copyright © 2015.

    Full Text Available Uniones libres or consensual union formation has increased in Mexico and this is not an exception in its Northern region. Information from the Mexican Population and Household Census of 2010 and the Survey on Reproductive Health of Adolescents in Baja California, 2006 show that unión libre as an preferential type of conjugal arrangement is more clearly manifested among the Baja California’s youth of both sexes in general and particularly among those residing in Tijuana and Rosarito. Also, union libre formation among the Baja California’s youth is extensively associated with childbearing what seems to indicate continuity in its traditional role in the Mexican family formation process, but this is happening in higher proportions among the young adults of the new generations.

    Intronic thyroid-stimulating hormone receptor polymorphisms have been associated with the risk for both Graves' disease and Graves' ophthalmopathy, but results have been inconsistent among different populations. We aimed to investigate the influence of thyroid-stimulating hormone receptor intronic polymorphisms in a large well-characterized population of GD patients. We studied 279 Graves' disease patients (231 females and 48 males, 39.80 ± 11.69 years old), including 144 with Graves' ophthalmopathy, matched to 296 healthy control individuals. Thyroid-stimulating hormone receptor genotypes of rs179247 and rs12885526 were determined by Real Time PCR TaqMan(®) SNP Genotyping. A multivariate analysis showed that the inheritance of the thyroid-stimulating hormone receptor AA genotype for rs179247 increased the risk for Graves' disease (OR = 2.821; 95 % CI 1.595-4.990; p = 0.0004), whereas the thyroid-stimulating hormone receptor GG genotype for rs12885526 increased the risk for Graves' ophthalmopathy (OR = 2.940; 95 % CI 1.320-6.548; p = 0.0083). Individuals with Graves' ophthalmopathy also presented lower mean thyrotropin receptor antibodies levels (96.3 ± 143.9 U/L) than individuals without Graves' ophthalmopathy (98.3 ± 201.9 U/L). We did not find any association between the investigated polymorphisms and patients clinical features or outcome. We demonstrate that thyroid-stimulating hormone receptor intronic polymorphisms are associated with the susceptibility to Graves' disease and Graves' ophthalmopathy in the Brazilian population, but do not appear to influence the disease course.

    Co-existence of thyroid nodules with Graves' disease has been reported in various studies. 10-15% of such nodules harbor thyroid cancer with papillary thyroid cancer being the commonest. Medullary thyroid cancer (MTC) in nodules associated with Graves' disease is rare. On literature survey, we came across 11 such cases reported so far. We report a 62-year-old female with Graves' disease who also had a thyroid nodule that on fine-needle aspiration cytology and the subsequent postthyroidectomy histopathological examination was reported to be MTC.

    Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

A partir de la interrogante acerca de la existencia de una crisis en la educación secundaria costarricense, las autoras plantean en este artículo la necesidad de vincular el análisis de esta situación con el contexto social en el que se produce. Concluyen que sí hay crisis en la educación secundaria y que entre otras formas, se expresa en la exclusión, la violencia social y su reproducción en las aulas, el malestar de los educadores, la naturaleza tecnocrática y fragmentaria del currículo, todo lo cual provoca la ausencia de sentido de la educación, tanto para jóvenes como para educadores. Se identifican algunas lecturas que sobre dicha crisis hacen diversas agencias sociales, por ejemplo, los medios de comunicación, el Ministerio de Educación Pública y las instituciones educativas. Se propone la construcción de un marco teórico desde el cual generar una lectura política y pedagógica acerca de la situación de la educación secundaria en Costa Rica, que propicie la reflexión y la toma de conciencia activa de quienes participamos, cotidianamente, en el trabajo educativo con los jóvenes.

    In Graves' disease, changes in orbital tissue and structure are caused by inflammatory infiltration, which induces increase of capillary permeability and breakdown of blood-tissue barriers. Using the uptake of 99m Tc-DTPA in inflammatory lesion, Eye/Brain radioactivity ratios in brain scintigraphy were evaluated in 15 normal controls and 40 Graves' patients. The results were as follows; 1) Eye/Brain radioactivity ratio was significantly higher in Graves' ophthalmopathy group than in control group (p 99m Tc-DTPA brain scintigraphy may be useful to determine the activity of Graves' ophthalmopathy and whether treatment of Graves' ophthalmopathy is necessary or not.

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients

    Graves' disease (GD) is associated with excess morbidity and mortality, but little is known about unnatural manners of death and the potential relation with Graves' orbitopathy (GO). This study investigated the risk of unnatural death in Graves' patients with and without orbitopathy compared to matched control populations. This was a cohort study covering all adult Danes (≥18 years) diagnosed with GD or GO during 1995-2012. Median follow-up time was 7.9 years (range 0-17.5 years). Utilizing the Danish Register of Causes of Death and the Danish National Patient Registry, 28,461 subjects with GD and 3965 with GO were identified and matched for age and sex with four subjects from the background population. The manner of death was identified, and hazard ratios (HR) for mortality due to unnatural deaths (accident, suicide, violence/homicide, and unknown) were calculated using Cox regression analyses, adjusted for pre-existing somatic and psychiatric morbidity. In Graves' disease overall (GD + GO), there was an increased risk of death from unknown unnatural manners (HR = 2.01 [confidence interval (CI) 1.17-3.45], p = 0.012) and of suicide, although the latter difference was not with certainty statistically significant (HR = 1.43 [CI 1.00-2.04], p = 0.053). There was no significant difference in risk of death from suicide in GD subjects compared to their controls (HR = 1.27 [CI 0.85-1.89], p = 0.253). However, GO patients had a significantly higher risk of death from suicide (HR = 2.71 [CI 1.16-6.32], p = 0.022). Mortality by suicide was increased in Graves' disease overall, most significantly in patients with GO, also after adjustment for pre-existing somatic and psychiatric disease. These findings indicate that GD and GO may have a significant role in the pathophysiological mechanisms of suicidal behavior. Beyond independent confirmation, reasons for this need to be explored in order to introduce preventive measures.

    2013-09-01

    Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

    Patients with Graves' disease were studied for two years during and after a twelve-month course of treatment. Disease activity was determined by repeated measurements of thyroidal uptake of [/sup 99m/Tc]pertechnetate during tri-iodothyronine administration. These in-vivo measurements of thyroid stimulation were compared with the results of in-vitro assays of Graves, immunoglobulin (TSH binding inhibitory activity--TBIA). There was no correlation between the thyroid uptake and TBIA on diagnosis. Pertechnetate uptake and TBIA both declined during the twelve months of antithyroid therapy. TBIA was detectable in sera from 19 of the 27 patients at diagnosis; in 11 of these 19 patients there was a good correlation (p less than 0.05) throughout the course of their disease between the laboratory assay of the Graves, immunoglobulin and the thyroid uptake. Probability of recurrence can be assessed but sustained remission of Graves' disease after treatment cannot be predicted from either measurement alone or in combination

    Full Text Available En Costa Rica, la informática dejó de ser una “nueva tecnología” para ser parte cotidiana de la vida de docentes y estudiantes. Sin embargo, el valor y tipo de uso de las computadoras y otros componentes de la informática en la enseñanza-aprendizaje aún son sujeto de debate entre los teóricos de la educación. La discusión se centra en un aspecto teórico y otro práctico. El teórico: ¿debe enseñarse cómo funciona la computadora o debe enseñarse simplemente a usarla? El práctico: ¿conviene usar la informática durante las lecciones, o sólo como un complemento extra-clase? Tras consultar a 231 mujeres y hombres dedicados a la enseñanza primaria y secundaria en toda Costa Rica, se encontró que la mayoría está a favor de cómo enseñar a usar la computadora (más que cómo funciona, tanto en el aula como fuera de ella. Sin embargo, en la vida real usan la informática más en actividades administrativas que educativas, y no han aprovechado el verdadero potencial de la tecnología de la información y comunicación (TIC en educación, por lo cual no han cosechado los logros que se esperan de su uso. Es urgente entonces un giro radical en la forma en que se apoya al personal docente y en cómo se emplean realmente las computadoras en la educación primaria y secundaria de Costa Rica.

    The association of external ionizing radiation to the head and neck and the subsequent development of hyperfunctioning parathyroid glands has been documented in recent years. This also has been demonstrated experimentally in animals. Despite the numbers of patients with Graves disease who have been treated with radioactive iodine, there are no reports in the literature of parathyroid surgery for hyperparathyroidism secondary to earlier treatment with radioactive iodine for Graves disease. This report describes the operative and pathologic findings in four patients with hyperparathyroidism. These patients had previously been treated with radioactive iodine for Graves disease. The pathologic findings at surgery included in three cases a single enlarged hyperplastic gland consistent with a parathyroid adenoma. One patient had hyperplasia of all four glands. The two largest glands and halves of the two remaining glands were removed. In a long-term follow-up of children and adolescents treated with radioactive iodine for Graves disease, Levy and Schumacher found calcium elevations in 10 of 159 patients. The increased incidence of hyperparathyroidism following radioactive iodine treatment for Graves disease in children and adolescents would seem several times higher than normal. Whether adults who have radioactive iodine treatment for Graves disease have a similar increase incidence is not known. Meanwhile it would seem reasonable to suggest that patients whose hyperthyroidism is treated with radioactive iodine should have their serum calcium levels determined at 5-year intervals

    Graves' disease is the most common cause of hyperthyroidism in the United States. Graves' disease occurs more often in women with a female:male ratio of 5:1 and a population prevalence of 1% to 2%. A genetic determinant to the susceptibility to Graves' disease is suspected because of familial clustering of the disease, a high sibling recurrence risk, the familial occurrence of thyroid autoantibodies, and the 30% concordance in disease status between identical twins. Graves' disease is an autoimmune thyroid disorder characterized by the infiltration of immune effector cells and thyroid antigen-specific T cells into the thyroid and thyroid-stimulating hormone receptor expressing tissues, with the production of autoantibodies to well-defined thyroidal antigens, such as thyroid peroxidase, thyroglobulin, and the thyroid-stimulating hormone receptor. The thyroid-stimulating hormone receptor is central to the regulation of thyroid growth and function. Stimulatory autoantibodies in Graves' disease activate the thyroid-stimulating hormone receptor leading to thyroid hyperplasia and unregulated thyroid hormone production and secretion. Below-normal levels of baseline serum thyroid-stimulating hormone receptor, normal to elevated serum levels of T4, elevated serum levels of T3 and thyroid-stimulating hormone receptor autoantibodies, and a diffusely enlarged, heterogeneous, hypervascular (increased Doppler flow) thyroid gland confirm diagnosis of Graves' disease (available at: http://supplements.amjmed.com/2010/hyperthyroid/faculty.php).

    We report a case of an adolescent boy with Down's syndrome and ESRD on hemodialysis who developed mild Graves' disease that was not amenable to radioablation, surgery, or ATDs. After 14 months of observation without resolution of Graves' disease, he successfully received a DDRT with a steroid minimization protocol. Thymoglobulin and a three-day course of steroids were used for induction and he was started on tacrolimus, MMF, and pravastatin for maintenance transplant immunosuppression. One month after transplantation, all biochemical markers and antibody profiling for Graves' disease had resolved and remain normal one yr later. © 2016 John Wiley & Sons A/S.

    The Patients with Graves disease hyperthyroidism are often accompanied by disorder of glycometabolism. β-cell dysfunction and insulin resistance play a main role in this disease, while the immune and genetic factors are also relevant with the disease. The blood glycose level can become normal gradually with the recovery of thyroid hormone after 131 I and antithyroid drug treatment. Therefore, the blood glycose level could be improved and complications could be prevented by early treatment in the patients with Graves disease hyperthyroidism accompanied with glycometabolism disorder is helpful for improving the blood glycose level.

    Microchimerism is the presence of cells from one individual in another genetically distinct individual. Pregnancy is the main cause of natural microchimerism through transplacental bidirectional cell trafficking between mother and fetus. The consequences of pregnancy-related microchimerism are under active investigation. However, many authors have suggested a close relationship linking fetal microchimerism and the development of autoimmune diseases. It has been more than ten years now since the demonstration of the presence of a significant high number of fetal microchimeric cells residing in thyroid glands from operated patients with Graves' disease. This intrathyroidal fetal microchimerism is an attractive candidate mechanism for the modulation of Graves' disease in pregnancy and the postpartum period. PMID:22577597

  8. Climate change and the northern elephant seal (Mirounga angustirostris population in Baja California, Mexico.

    Full Text Available The Earth's climate is warming, especially in the mid- and high latitudes of the Northern Hemisphere. The northern elephant seal (Mirounga angustirostris breeds and haul-outs on islands and the mainland of Baja California, Mexico, and California, U.S.A. At the beginning of the 21st century, numbers of elephant seals in California are increasing, but the status of Baja California populations is unknown, and some data suggest they may be decreasing. We hypothesize that the elephant seal population of Baja California is experiencing a decline because the animals are not migrating as far south due to warming sea and air temperatures. Here we assessed population trends of the Baja California population, and climate change in the region. The numbers of northern elephant seals in Baja California colonies have been decreasing since the 1990s, and both the surface waters off Baja California and the local air temperatures have warmed during the last three decades. We propose that declining population sizes may be attributable to decreased migration towards the southern portions of the range in response to the observed temperature increases. Further research is needed to confirm our hypothesis; however, if true, it would imply that elephant seal colonies of Baja California and California are not demographically isolated which would pose challenges to environmental and management policies between Mexico and the United States.

    Full Text Available Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

    Neonatal Graves' disease presenting as conjugated hyperbilirubinemia is a diagnostic challenge because the differential includes a gamut of liver and systemic diseases. We present a unique case of neonatal Graves' disease in a premature infant with conjugated hyperbilirubinemia born to a mother with hypothyroidism during pregnancy and remote history of Graves' disease. Infant was treated with a combination of methimazole, propranolol, and potassium iodide for 4 weeks. Thyroid function improved after 8 weeks of treatment with full recovery of thyroid function, disappearance of thyroid-stimulating antibodies, and resolution of failure to thrive and conjugated hyperbilirubinemia. This case provides several clinical vignettes as it is a rare, severe, presentation of an uncommon neonatal disease, signs, symptoms, and clinical history presented a diagnostic challenge for neonatologists and endocrinologists, normal newborn screen was misleading, and yet timely treatment led to a full recovery.

    The onset of Graves disease during pregnancy exposes the neonate to the risk of hyperthyroidism. The newborn must be monitored and treatment modalities known to ensure early treatment of the newborn. We report on the case of an infant born at term of a mother with Graves disease discovered during pregnancy. He was asymptomatic during the first days of life, before declaring the disease. Neonatal hyperthyroidism was confirmed by hormonal assays. Hyperthyroidism was treated with antithyroid drugs and propranolol with a satisfactory clinical and biological course. Neonatal hyperthyroidism should be systematically sought in infants born to a mother with Graves disease. The absence of clinical signs during the first days of life does not exclude the diagnosis. The duration of monitoring should be decided according to the results of the first hormonal balance tests. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  14. Psychiatric manifestations of Graves' hyperthyroidism: pathophysiology and treatment options.

    Bunevicius, Robertas; Prange, Arthur J

    2006-01-01

    Graves' disease is an autoimmune disorder that is the most common cause of hyperthyroidism. Other symptoms associated with the disease are goitre, ophthalmopathy, and psychiatric manifestations such as mood and anxiety disorders and, sometimes, cognitive dysfunction. Graves' hyperthyroidism may result in these latter manifestations via the induction of hyperactivity of the adrenergic nervous system. This review addresses the psychiatric presentations, and their pathophysiology and treatment, in patients with hyperthyroidism, based on literature identified by a PubMed/MEDLINE database search. Although the focus is on mental symptoms associated with Graves' disease, it is not always clear from the literature whether patients had Graves' disease: in some studies, the patients were thought to have Graves' disease based on clinical findings such as diffuse goitre or ophthalmopathy or on measurements of thyroid antibodies in serum; however, in other studies, no distinction was made between Graves' hyperthyroidism and hyperthyroidism from other causes. Antithyroid drugs combined with beta-adrenoceptor antagonists are the treatments of choice for hyperthyroidism, as well as for the psychiatric disorders and mental symptoms caused by hyperthyroidism. A substantial proportion of patients have an altered mental state even after successful treatment of hyperthyroidism, suggesting that mechanisms other than hyperthyroidism, including the Graves' autoimmune process per se and ophthalmopathy, may also be involved. When psychiatric disorders remain after restoration of euthyroidism and after treatment with beta-adrenoceptor antagonists, specific treatment for the psychiatric symptoms, especially psychotropic drugs, may be needed.

  15. The Role of Oxidative Stress on the Pathogenesis of Graves' Disease

    2012-01-01

    Full Text Available Graves' disease is a most common cause of hyperthyroidism. It is an autoimmune disease, and autoimmune process induces an inflammatory reaction, and reactive oxygen species (ROSs are among its products. When balance between oxidants and antioxidants is disturbed, in favour of the oxidants it is termed “oxidative stress” (OS. Increased OS characterizes Graves' disease. It seems that the level of OS is increased in subjects with Graves' ophthalmopathy compared to the other subjects with Graves' disease. Among the other factors, OS is involved in proliferation of orbital fibroblasts. Polymorphism of the 8-oxoG DNA N-glycosylase 1 (hOGG1 involved in repair of the oxidative damaged DNA increases in the risk for developing Grave's disease. Treatment with glucocorticoids reduces levels of OS markers. A recent large clinical trial evaluated effect of selenium on mild Graves' ophthalmopathy. Selenium treatment was associated with an improved quality of life and less eye involvement and slowed the progression of Graves' orbitopathy, compared to placebo.

    We present two patients with Graves' disease and concurrent myasthenia gravis. The impact of the dual diagnosis on the clinical course and the potential for a delayed diagnosis of myasthenia gravis is discussed. Patient 1, a 28-year-old man was diagnosed with Graves' disease following his second respiratory arrest. His history was strongly suggestive of a second pathology. Patient 2, a 66-year-old Cantonese woman with established Graves' disease presented with thionamide-related neutropaenia. Examination revealed bilateral ptosis and right lateral rectus palsy. Both patients had thyrotoxicosis secondary to Graves' disease with concurrent myasthenia gravis. Although neuromuscular weakness is common in Graves' disease, coexisting myasthenia gravis (MG) is rare and can cause profound morbidity. Ocular signs in both diseases may cause diagnostic confusion although ptosis suggests coexisting MG. In both cases, the thyrotoxicosis delayed the diagnosis of MG. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    The association between vitamin D levels and Graves' disease is not well studied. This update review aims to further analyze the relationship in order to provide an actual view of estimating the risk. We searched for the publications on vitamin D and Graves' disease in English or Chinese on PubMed, EMBASE, Chinese National Knowledge Infrastructure, China Biology Medical and Wanfang databases. The standardized mean difference (SMD) and 95% confidence interval (CI) were calculated for the vitamin D levels. Pooled odds ratio (OR) and 95% CI were calculated for vitamin D deficiency. We also performed sensitivity analysis and meta-regression. Combining effect sizes from 26 studies for Graves' disease as an outcome found a pooled effect of SMD = -0.77 (95% CI: -1.12, -0.42; p Graves' disease were more likely to be deficient in vitamin D compared to the controls (OR = 2.24, 95% CI: 1.31, 3.81) with a high heterogeneity (I2 = 84.1%, p Graves' disease.

    Objective: To explore the value of serum thyrotrophin receptor antibody (TRAb) on the pathological mechanism of Graves ophthalmopathy. Methods: Two hundred and nineteen newly diagnosed Graves disease patients who were divided into Graves ophthalmopathy group (n=121) and without Graves ophthalmopathy group (n=98) were tested serum concentration with thyroid function, thyroperoxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and TRAb. According to the consensus statement of the European Group on Graves ophthalmopathy, clinical activity score (CAS) and severity evaluation were carried out on Graves ophthalmopathy patients. Results: There was no significant difference in serum concentration of free thyroxine (FT 4 ), free triiodothyronine (FT 3 ), TPOAb and TRAb between the Graves ophthalmopathy group and the without Graves ophthalmopathy group. Serum concentration of TRAb was not correlated with the severity and CAS of Graves ophthalmopathy. Conclusions: The CAS and the severity of Graves ophthalmopathy were irrelevant to the serum concentration of TRAb. Therefore, the correlation between TRAb and Graves ophthalmopathy still needs further study. (authors)

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients.

    Graves' disease (GD) accounts for 10-15% of thyroid disorders in patients less than 18 years of age. It is the most common cause of thyrotoxicosis in children and accounts for at least 95% of cases in children. Pediatric Treatment of Graves' disease consists of anti-thyroid drugs, radioactive iodide and thyroidectomy but the optimal treatment of GD in children is still controversial. To review treatment outcome of pediatric Graves' disease in Albania. Descriptive review of 15 children with Graves' disease, diagnosed from Jan.2007 to Dec. 2013, at the Division of Pediatric Endocrinology, Department of Pediatrics, University Hospital Centre "Mother Teresa", Albania was performed. All patients, mean age 10.56 ± 3.37 years, (range 2.02-16.09 years) were presented with goiter and increased serum FT4, mean 39.80 ± 16.02 ng/mL, (range 21.0-74.70 ng/mL), serum FT3, mean 12.98 ± 3.45 pg/mL, (range 6.90 -17.90 pg/mL) and suppressed TSH levels, mean 0.02 ± 0.01 mUI/L, (range 0.01-0.05 mUI/L). Anti TSH Receptor were positive in 100% of patients mean value 6.51 ± 3.61 UI/mL (range 1.63 - 14.10 UI/mL). Anti-thyroglobulin and Anti-TPO antibodies were positive in 60% and 46.6% respectively. Clinical course of 15 patients after treatment with anti-thyroid drugs mainly MMI for 3.19 ± 1.48 (range 0.60 - 6.20) years is as follows: seven (46.66%) underwent remission, five out of seven (71.41%) who underwent remission, relapsed. Three of them (20%) were treated with I(131), and two (13.3%) underwent to total thyroidectomy. MMI was the most common first line therapy in the presented patients with Graves' disease. Remission rate was 46.66% after an average 1.48 ± 0.71 years (range 0.60 - 2.70 years) of treatment with anti-thyroid drugs. Remission period was 2.70 ± 0.36 years (2.1 - 3.1 years) Relapse occurred in 71.41% of patient. I(131) and thyroidectomy were used as second line therapy in the present study.

    HTLV-I carriers or patients with HTLV-I associated myelopathy (HAM) are prone to immune-mediated inflammatory disorders. We present a 44-year-old female with HAM who developed Graves' disease. She developed severe Graves' ophthalmopathy shortly after 131 I therapy, concurrently with a remarkable increase in TSH-receptor antibody titer. Ophthalmopathy was aggravated in spite of prednisolone therapy and euthyroidism being maintained by thyroxine replacement. Uveitis also developed after 131 I therapy and iridocyclitis finally required trabeculotomy. This case suggests that HAM patients may have a higher risk of immune-mediated Graves' ophthalmopathy after 131 I therapy.(author)

    Graves' orbitopathy is caused by intraorbital inflammatory reaction due to autoimmune thyroid disease. In most cases the diagnosis is based on the coexistence of typical eye signs and hyperthyroidism symptoms. In presented case, the absence of thyroid dysfunction implicated performance of differential diagnosis. Among many available diagnostic tools nuclear magnetic resonance seems to be the most accurate in confirmation of diagnosis of Graves' orbitopathy.

    Full Text Available El alto índice de reprobación en la escuela secundaria mexicana, que se convierte en el antecedente inmediato de la exclusión vía el abandono escolar, es un problema grave en la educación mexicana. Aunque se conocen datos sobre diversidad de factores que pretenden comprender el fenómeno, poco se ha incursionado en el campo de los significados que los propios alumnos tienen al respecto. Aquí se pretende abonar a este propósito al analizar los significados hacia la escuela y su particular situación académica que dos alumnos con altos índices de reprobación presentan y se hacen candidatos a la exclusión. Esto es abordado desde la teoría de las representaciones sociales, ya que ello permitirá conocer la subjetividad producida al respecto. Usando una metodología cualitativa, es como se reconocen en la construcción de las representaciones sociales, la existencia de cuatro dimensiones que configuran esta realidad: el mercado laboral, la escuela, la familia, y los alumnos adolescentes, quienes aceptan en lo general, pero no sumisamente, que la escuela es un factor de movilidad social. Es un mal necesario. Las representaciones sociales en estos casos, revelan su carácter dialéctico y contradictorio, crítico y conformista hacia la escuela.

    The number of patients achieving long-term survival following neck irradiation for Hodgkin's disease and other malignancies is increasing. Paralleling this increase in survivors is the development of late complications of the therapy itself. Eleven patients have previously been reported who developed Graves ophthalmopathy 18 months to seven years after receiving neck radiotherapy for nonthyroidal malignancies. The seven patients who had HLA typing were all HLA-B8 negative, despite the reported association of the HLA-B8 antigen with Graves disease. A patient who is HLA-B8 positive who developed Graves ophthalmopathy and hyperthyroidism nine years after receiving mantle radiotherapy for Hodgkin's disease is reported. It is recommended that Graves disease be included among the thyroid diseases that receive consideration during follow-up of patients who have received mantle radiotherapy

    To evaluate the diagnostic accuracy of chest CT findings to diagnose Grave's disease in pulmonary hypertension. We retrospectively evaluated chest CT and the medical records of 13 patients with Grave's disease with (n=6) or without pulmonary hypertension (n=7) and in 17 control patients. Presence of iso-attenuation of diffusely enlarged thyroid glands compared with adjacent neck muscle on non-enhanced CT as a diagnostic clue of Grave's disease, and assessment of pulmonary hypertension on CT has high diagnostic accuracy. Chest CT has the potential to diagnose Grave's disease with pulmonary hypertension in the absence of other information. Copyright © 2017 Elsevier Inc. All rights reserved.

Actualmente los distintos agentes educativos y sociales muestran una gran preocupación por las crecientes denuncias del alumnado de esta etapa educativa. A tal fin, se realiza un proceso sistemático de indagación documental en distintas bases de datos sobre estudios, en el contexto educativo español, realizados en torno a esta temática. Se concluye, por un lado, que el profesorado encuestado, conoce y desarrolla más acciones de prevención primaria y secundaria sobre el acoso escolar que de prevención terciaria. Que las acciones primarias y secundarias tienen un enfoque más educativo que punitivo o sancionador y buscan principalmente la generación de un clima adecuado de convivencia tanto en el centro como en el grupo-clase. Por otro lado, en el nivel de prevención terciaria, desarrollan acciones centradas en hablar con el alumnado, aplicar las normas de disciplina y convivencia y derivar los casos a los departamentos de orientación de sus centros.

    Purpose behind developing these guidelines: Over one decade ago, the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2006" (Japan Thyroid Association (JTA)) were published as the standard drug therapy protocol for Graves' disease. The "Guidelines for the Treatment of Childhood-Onset Graves' Disease with Antithyroid Drug in Japan, 2008" were published to provide guidance on the treatment of pediatric patients. Based on new evidence, a revised version of the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2006" (JTA) was published in 2011, combined with the "Handbook of Radioiodine Therapy for Graves' Disease 2007" (JTA). Subsequently, newer findings on pediatric Graves' disease have been reported. Propylthiouracil (PTU)-induced serious hepatopathy is an important problem in pediatric patients. The American Thyroid Association's guidelines suggest that, in principle, physicians must not administer PTU to children. On the other hand, the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2011" (JTA) state that radioiodine therapy is no longer considered a "fundamental contraindication" in children. Therefore, the "Guidelines for the Treatment of Childhood-Onset Graves' Disease with Antithyroid Drug in Japan, 2008" required revision.

    BACKGROUND: Premature hair greying has been associated with low bone mineral density (BMD), and it may be more frequent in Graves\\' disease. AIMS: To determine whether premature greying is associated with reduced BMD in women with Graves\\' disease and in control women, and to examine whether premature greying is more common in Graves\\' disease. METHODS: Premature greying (> 50% grey by 40 years) and BMD were determined in 44 women with a history of Graves\\' disease and 133 female controls referred for routine BMD measurement. Exclusion criteria included diseases or drugs known to affect BMD. RESULTS: Mean Z and T scores at the lumbar spine were significantly lower (P < 0.04) in subjects with premature greying than in those not prematurely grey among women with Graves\\' disease, but not among control women. Multiple regression confirmed this difference between Graves\\' and control women (P = 0.041). There were no differences at other measurement sites. Of Graves\\' patients, 36% were prematurely grey compared with 25% of control women (P = 0.14). CONCLUSION: Premature greying may be a weak marker for reduced BMD in women with a history of Graves\\' disease, but it is not a marker in normal women.

    The best preoperative examination in Graves' disease with thyroid cancer still remains uncertain. The objectives of the present study were to investigate the prevalence of thyroid cancer in Graves' disease patients, and to identify the predictive factors and ultrasonographic features of thyroid cancer that may aid the preoperative diagnosis in Graves' disease. This retrospective study included 423 patients with Graves' disease who underwent surgical treatment from 2002 to 2012 at our institution. The clinical features and ultrasonographic findings of thyroid nodules were recorded. The diagnosis of thyroid cancer was determined according to the pathological results. Thyroid cancer was discovered in 58 of the 423 (13.7 %) surgically treated Graves' disease patients; 46 of those 58 patients had thyroid nodules, and the other 12 patients were diagnosed with incidentally discovered thyroid carcinomas without thyroid nodules. Among the 58 patients with thyroid cancer, papillary microcarcinomas were discovered in 50 patients, and multifocality and lymph node involvement were detected in the other 8 patients. Multivariate regression analysis showed younger age was the only significant factor predictive of metastatic thyroid cancer. Ultrasonographic findings of calcification and intranodular blood flow in thyroid nodules indicate that they are more likely to harbor thyroid cancers. Because the influencing factor of metastatic thyroid cancers in Graves' disease is young age, every suspicious nodule in Graves' disease patients should be evaluated and treated carefully, especially in younger patients because of the potential for metastasis.

    Graves' disease is an autoimmune disorder in which inappropriate stimulation of the thyroid gland results in unregulated secretion of thyroid hormones resulting in hyperthyroidism. Graves' disease is the most common cause of autoimmune hyperthyroidism during pregnancy. Treatment options for Graves' disease include thioamide therapy, partial or total thyroidectomy, and radioactive iodine. In this article, we review guideline recommendations for Graves' disease treatment in women of reproductive age including the recent guideline from the American College of Obstetricians and Gynecologists. Controversy regarding appropriate thioamide therapy before, during, and after pregnancy is reviewed. Surgical and radioactive iodine therapy considerations in this patient population are also reviewed. In patients who may find themselves pregnant during therapy or develop Graves' disease during their pregnancy, consideration should be given to the most appropriate treatment course for the mother and fetus. Thioamide therapy should be used with either propylthiouracil or methimazole at appropriate doses that target the upper range of normal to slightly hyperthyroid to avoid creating hypothyroidism in the fetus. Consideration should also be given to the adverse effects of thioamide, such as agranulocytosis and hepatotoxicity, with appropriate patient consultation regarding signs and symptoms. Individuals who wish to breastfeed their infants while taking thioamide should receive the lowest effective dose. Surgery should be reserved for extreme cases and limited to the second trimester, if possible. Radioactive iodine therapy may be used in nonpregnant individuals, with limited harm to future fertility. Radioactive iodine therapy should be withheld in pregnant women and those who are actively breastfeeding. Clinicians should keep abreast of developments in clinical trials and evidence-based recommendations regarding Graves' disease in reproductive-age women for any changes in evidence

    Graves' disease is the most frequent cause of hyperthyroidism, affecting mainly young aged women, with an etiology of autoimmune basis. One of its manifestations, Graves' ophthalmopathy whose pathophysiology is unknown, represents one of the greatest therapeutic challenges in these patients, because they require aggressive treatment with steroids and multiple subsequent reconstructive surgeries in certain cases. It also represents a high burden to the health system. Drugs targeting B cells have been very effective for many autoimmune diseases. Rituximab is a murine humanized monoclonal antibody against CD20 + cells currently being studied in various autoimmune diseases including Graves' disease. The objective of this paper is to expose possible mechanisms by which rituximab could act in both hyperthyroidism and ophthalmopathy of Graves' disease, as well as the experience with its use acquired so far. The employment of rituximab in recently diagnosed patients or with mild ophthalmopathy is questionable with the evidence available today however, we think that it may have a role in refractory cases or those who have a contraindication for steroid use.

    Graves' disease is an autoimmune disease of the thyroid gland mediated by T cells. CD28, a member of costimulatory molecules, plays a pivotal role in regulating T-cell responses. Plasma-soluble CD28 is one form of CD28 in peripheral blood. To investigate the concentrations of soluble CD28 in patients with Graves' disease, we used a sensitive dual monoclonal antibody sandwich enzyme-linked immunosorbent assay (ELISA) to detect the soluble form of CD28. Our results suggested that mean concentrations of soluble CD28 in plasma of patients with Graves' disease were 1.79 ±1.52 ng/ml, and levels of soluble CD28 in healthy subjects were only 0.83 ±1.35 ng/ml. Concentrations of soluble CD28 detected in patients with Graves' disease were significantly higher than those of healthy subjects (p Graves' disease. Therefore, aberrant elevation of plasma-soluble CD28 in patients with Graves' disease may reflect the dysregulation of immune system, and may serve as a useful biomarker in Graves' disease diagnosis.

    Objective: To study the incidence of Graves' disease and associated factors. Methods: From 1997.4 to 1999.12, by using cluster and stratified sampling, total of 31530 people aged 6 years and over were surveyed epidemiologically for Graves' disease in five districts and one county of Tianjin area where the study subjects had been resided for at least one year. The researching team consisted of endocrinologists, epidemiologists and technicians and was divided into three branches, they served as investigators, professional experts and technicians, respectively. The serum thyroid hormones, thyroid antibodies, iodine in table salt, urine iodine and B-US were examined for the suspected cases, the final diagnoses were concluded by the professional experts. Results: Eighty-nine patients with Graves' disease were confirmed, 26 (0.166%) of them were males and 63(0.397%) of them were females, the total incidence was 0.282%. The incidence significantly associated with sex (female higher than male, P<0.001), age (50-60 group for male and 30-40 group for female higher than others, P<0.001) and family history (the patients with vs without family history, P<0.001). The survey showed an ascending trend of incidence of Graves' disease, along with decreasing of goiter rate and increasing of iodine contents in table salt and in urine. Further research work should be pursued. Conclusion: This study may provide some theoretical basis for prevention and treatment of Graves' disease

    Ignacio José Subijana

    2018-01-01

    Full Text Available El abuso sexual en la infancia es un fenómeno relativamente frecuente y tiene graves consecuencias para el desarrollo del menor. La víctima suele demorar la revelación del abuso sexual por temor a una reacción negativa de su entorno o por amenazas del abusador. El abuso sexual infantil se lleva a cabo habitualmente en la intimidad, por lo que no hay testigos ni pruebas externas de lo ocurrido. Por ello, cuando estos casos se denuncian en los tribunales, a menudo el testimonio del menor es la prueba de cargo única o más significativa. En este artículo se proponen diversas recomendaciones para, cuando sea factible su presencia en el juicio, mejorar la calidad del testimonio aportado por los menores en el sistema judicial, protegiéndoles también de la victimización secundaria, al mismo tiempo que se garantiza la presunción de inocencia de los acusados. Se plantean, al respecto, algunas sugerencias para armonizar los derechos de los acusados y de las víctimas.

    Objective: To study the changes of hepatofibrosis markers (IV-C, PC III, HA, LN) in Graves' disease. Methods: Serum levels of hepatofibrosis were measured with RIA in 40 patients with Graves' disease (CD) before any treatment and 35 patients with Graves' disease after successful anti-thyroid drug therapy as well as in 30 controls. Results: The serum IV-C and PC III levels in GD patients were significant higher than those in controls before treatment (P<0.01). After successful treatment, the IV-C, PC III levels dropped markedly (vs before treatment, P<0.01). However, there were no significant differences among the serum HA, LN levels in all the subjects tested. Conclusion: Serum levels of IV-C and PC III increased markedly with hyperthyroidim. When IV-C and PC III levels were taken for assessment of degree of hepatofibeosis, GD must be ruled out first. (authors)

Los datos se derivaron de una investigación etnográfica y de un programa de atención psicológica desarrollado en tres escuelas secundarias mexicanas durante cuatro años. En estas escuelas los y las maestras consideran que la indisciplina, el bajo rendimiento y la violencia y agresividad entre estudiantes, son los principales conflictos existentes. Sin embargo, hay estudiantes que no tienen mala conducta en el contexto escolar pero tienen problemas emocionales y sociales que necesitan atención psicológica pero que son poco visibles para los maestros y maestras. En el artículo se exponen aspectos de los discursos y prácticas sociales de los participantes en la escuela que obstaculizan el desarrollo del programa de atención psicológica. Se ofrecen ejemplos sobre la labor de intervención psicológica y se enfatiza la necesidad de tomar en cuenta las perspectivas de los actores para ajustar las estrategias de intervención a la realidad cultural de estos grupos sociales. También se exponen los alcances y las limitaciones del programa implementado. Finalmente, se hacen sugerencias acerca de cómo los profesionales de la psicología deben proceder para ayudar en procesos de negociación entre maestros y estudiantes, para mantener una actitud neutral y objetiva en la intervención y para entender la complejidad de las acciones humanas que están en juego en la construcción de los problemas.

    Hyperthyroidism caused by Graves' disease is common in women, yet little is known about risk factors for the disease. We sought to determine whether lifestyle factors, including smoking, alcohol consumption, physical activity level, and body mass index, are risk factors for Graves' hyperthyroidism. This analysis was conducted using data from the Nurses' Health Study II, among 115109 women aged 25 to 42 at entry. Incident reports of women with Graves' hyperthyroidism, confirmed to have the disorder, were included. During 1 328 270 person-years of follow-up, incident diagnoses of Graves' hyperthyroidism were confirmed in 543 women; the 12-year incidence was 4.6 per 1000 women. Cigarette smoking was a predictor of Graves' hyperthyroidism. The hazard ratio among current smokers was 1.93 (95% confidence interval [CI], 1.54-2.43), and among past smokers it was 1.27 (95% CI, 1.03-1.56), after adjusting for recent pregnancy, parity, and other variables. Among current smokers, the hazard ratio increased with the intensity of smoking and was 2.63 (95% CI, 1.71-4.04) among women who smoked 25 or more cigarettes daily. Obesity was associated with a decreased risk of Graves' hyperthyroidism. The hazard ratio for the disorder among women with a body mass index of 30 kg/m(2) or higher was 0.68 (95% CI, 0.49-0.92). Alcohol intake and physical activity level were not associated with risk of Graves' hyperthyroidism. Smoking is a risk factor for Graves' hyperthyroidism in women. Obesity may be associated with a reduced risk, although weight loss as the first manifestation of hyperthyroidism cannot be excluded.

    Primary biliary cirrhosis (PBC), which predominantly affects women, has been associated with various autoimmune diseases. Although hypothyroidism accompanying PBC is well documented, the concomitance of PBC and hyperthyroidism is rare. Herein, we report the case of a 62-year-old man who was diagnosed with PBC several years after the development of Graves' disease. This is the first case of a male patient developing PBC with Graves' disease. Both serum alanine aminotransferase levels and serum thyroid hormone levels were normalized after the administration of thiamazole for Graves' disease. However, the cholestatic liver enzyme abnormalities continued, indicating that the PBC was actualized by the administration of thiamazole. After starting ursodeoxycholic acid treatment, cholestatic liver enzyme abnormalities improved. Taken together, when a cholestatic pattern of liver enzymes is observed during follow-up for Graves' disease, an association between Graves' disease and PBC should be considered as a differential diagnosis.

    Jaundice in Grave's diseases is uncommon, but when it does occur, complication of thyrotoxicosis (heart failure/infection) or intrinsic liver disease should be considered. Grave's disease can cause asymptomatic elevation of liver enzymes, jaundice and rarely acute liver failure. It is associated with other autoimmune diseases like autoimmune hepatitis, or primary biliary cirrhosis. The cause of jaundice in Grave's disease is multifactorial. PMID:25755537

    Treatment options for Grave's disease include radio-iodine ablation, which is the standard treatment in the USA, antithyroid drug therapy, which is popular in Japan, and surgery, which is commonly employed in Europe and India. There are very few reports about the outcome of surgery in Grave's disease in the Indian setting. Surgery for Grave's disease is an attractive option in under developed countries to cut short prolonged drug treatment, costly follow up and avoid the need for radio-isotope facilities for 1311 ablation. Aim of the present study was to assess the result of subtotal thyroidectomy in 32 cases of Grave's Disease referred for surgery by the endocrinologist in a teaching hospital. Patients were prepared for surgery with Lugol's iodine and propranalol. Subtotal thyroidectomy was performed by a standard technique, which included dissection and exposure of recurrent laryngeal nerves and parathyroid glands. Actual estimation of weight of the remnant gland was not part of the study. Duration of follow up ranged from 6 months to 4 years. 13 of 32 cases were males. Age ranged from 20 to 57 years. There was 1 death in the immediate post-operative period. There were no cases of permanent hypoparathyroidism or recurrent laryngeal nerve palsy. 1 patient developed temporary hypoparathyroidism. 1 patient developed recurrence of hyperthyroidism and 3 cases developed hypothyroidism all within 2 years of surgery. The study has demonstrated the safety and effectiveness of surgery for Grave's Disease in comparison to the reported high incidence of hypothyroidism following radio-iodine therapy and high recurrence rate after anti thyroid drug therapy.

  5. Prevention of Graves' ophthalmopathy.

    Smoking is the most important risk factor for the occurrence/progression of Graves' ophthalmopathy (GO), as well as for its lower/slower response to immunosuppression. Accordingly, refrain from smoking should be urged, both as primary prevention (removal of risk factors in Graves' patients without GO), secondary prevention (early detection and treatment of asymptomatic/very mild GO) and tertiary prevention (reduction of complications/disability of overt GO). A 6-month course of 200 μg/day sodium selenite can prevent progression of mild GO to more severe GO and is, therefore, a form of secondary prevention and, probably, primary prevention. Correction of thyroid dysfunction and stable maintenance of euthyroidism are important preventive measures. The optimal treatment for hyperthyroidism in patients with GO is uncertain, because evidence demonstrating the superiority of antithyroid drugs over thyroid ablation (radioiodine, thyroidectomy, or both) is lacking. If radioiodine is used, low-dose steroid prophylaxis is recommended, particularly in smokers, to prevent radioiodine-associated GO progression. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Actualmente existen siete especies de tortugas marinas, todas amenazadas o en riesgo inminente de extinción. Los estudios con ADN mitocondrial han permitido hacer acercamientos sobre filogenia, evolución, rutas migratorias y centros de dispersión, además para la identificación de polimorfismos y haplotipos, siendo base para planes de manejo y conservación. El presente estudio representa la primera descripción comparada de la estructura primaria y secundaria del ARNtTrp mitocondrial en tortugas marinas. Se realizó un alineamiento múltiple de 26 secuencias del gen que codifica para el ARNtTrp y se propuso la estructura secundaria utilizando el programa ARWEN. Se identificaron potenciales interacciones terciarias por homología comparada con el ARNtTrp de mamíferos. Los resultados mostraron una secuencia consenso de 76 bases con siete regiones conservadas que representan el 76 % de la molécula. Se identificaron polimorfismos que representan tres haplotipos para C. caretta, dos para C. mydas y uno para cada una de las demás especies. Las estructuras secundarias mostraron cambios nucleotídicos puntuales para cada especie y también mostraron que el tallo aceptor, el brazo TψC y el bucle anticodón son motivos conservados en el ARNtTrp de las tortugas marinas. Se encontró un enlace no canónico tipo A-A en el tallo DHU que podría considerarse característico de tortugas marinas. Además, se obtuvo una estructura secundaria consenso en donde se identificaron las siete regiones conservadas, seis posibles interacciones terciarias y el bucle DHU como región variable.

    Graves' disease, the most common form of hyperthyroidism in iodine-replete countries, is associated with the presence of immunoglobulins G (IgGs) that are responsible for thyroid growth and hyperfunction. In this article, we report the unusual case of a patient with acromegaly and a severe form of Graves' disease. Here, we address the issue concerning the role of growth hormone (GH) and insulin-like growth factor 1 (IGF1) in influencing thyroid function. Severity of Graves' disease is exacerbated by coexistent acromegaly and both activity indexes and symptoms and signs of Graves' disease improve after the surgical remission of acromegaly. We also discuss by which signaling pathways GH and IGF1 may play an integrating role in regulating the function of the immune system in Graves' disease and synergize the stimulatory activity of Graves' IgGs. Clinical observations have demonstrated an increased prevalence of euthyroid and hyperthyroid goiters in patients with acromegaly.The coexistence of acromegaly and Graves' disease is a very unusual event, the prevalence being Graves' disease associated with acromegaly and show that surgical remission of acromegaly leads to a better control of symptoms of Graves' disease.

    Total thyroidectomy for treatment of Graves' disease is controversial and much of the debate centers on the concern for complications. The purpose of this study was to evaluate the morbidity of total thyroidectomy for Graves' disease and determine if it is different than for patients with nontoxic nodular goiter. The rates of life threatening neck hematoma, recurrent laryngeal nerve (RLN) injury, transient hypocalcemia, and hypoparathyroidism were determined for consecutive patients with Graves' disease treated with total thyroidectomy from 1996 to 2010. Results were compared with patients who underwent total thyroidectomy for nontoxic nodular goiter during the same period, matched for the weight of the excised thyroid gland. Total thyroidectomy was performed in 111 patients with Graves' disease (group I) and 283 patients with nontoxic nodular goiter (group II). Parathyroid autotransplantation was performed in 31(28%) patients in group I and 98 (35%) patients in group II (P = NS). Comparative analysis of morbidity revealed no significant difference in neck hematoma, 0(0%) (I) versus 3(1%) (II); permanent RLN injury, 0(0%) (I) versus 2(1%) (II); and permanent hypoparathyroidism in 1(1%) (I) versus 1 (0.4%) (II) (P = NS). Transient hypocalcemia was more common in patients with Graves' disease, 80(72%) (I) versus 170 (60%) (II) (P Graves' disease; only transient hypocalcemia occurred more often than in patients with nodular goiter. Total thyroidectomy should be presented as a therapeutic option for all patients with Graves' disease. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available Graves' disease is the most common form of autoimmune thyroid disorder, characterized by hyperthyroidism due to circulating autoantibodies. To address the pathological features and establish a therapeutic approach of this disease, an animal model carrying the phenotype of Graves' disease (GD in concert with Graves' Ophthalmopathy (GO will be very important. However, there are no ideal animal models that are currently available. The aim of the present study is to establish an animal model of GD and GO disease, and its pathological features were further characterized.A recombinant plasmid pcDNA3.1- T289 was constructed by inserting the TSHR A-subunit gene into the expression vector pcDNA3.1, and genetic immunization was successfully performed by intramuscular injection of the plasmid pcDNA3.1-T289 on female 8-week-old BALB/c mice. Each injection was immediately followed by in vivo electroporation using ECM830 square wave electroporator. Morphological changes of the eyes were examined using 7.0T MRI scanner. Levels of serum T4 and TSHR antibodies (TRAb were assessed by ELISA. The pathological changes of the thyroid and orbital tissues were examined by histological staining such as H&E staining and Alcian blue staining.More than 90% of the immunized mice spontaneously developed goiter, and about 80% of the immunized mice manifested increased serum T4 and TRAb levels, combined with hypertrophy and hyperplasia of thyroid follicles. A significantly increased synthesis of hyaluronic acid was detected in in the immunized mice compared with the control groups.We have successfully established an animal model manifesting Graves' hyperthyroidism and ophthalmopathy, which provides a useful tool for future study of the pathological features and the development of novel therapies of the diseases.

    2013-07-01

    To report a rare case of Graves' disease without ophthalmopathy presenting with pretibial myxedema (PM) as an initial presentation. We present the clinical history, physical findings, laboratory studies and biopsy data of a 62-year-old man with a history of uncontrolled type 2 diabetes (DM2) presenting with arm and leg skin lesions in the absence of other physical findings. Histopathology confirmed PM. Graves' disease and its association with PM without Graves' ophthalmopathy and the pertinent literature are reviewed. A 60-year-old man with a history of uncontrolled DM2 presented for glycemic management. He described symptoms of anxiety, insomnia and fatigue for the last 5 to 6 months. He described diffuse chest pain, occasionally associated with palpitations, and a 50-pound weight loss. He also complained of severe itching and burning of his arms and legs for the past several months. Subsequent thyroid studies revealed hyperthyroidism suggestive of Graves' disease. In the interim, he was hospitalized for atrial flutter and was cardioverted. After being started on methimazole, his symptoms abated. His skin lesions were biopsied, and the leg biopsy was consistent with PM. He however had no lid lag or proptosis characteristic of Graves' disease. He subsequently underwent radioiodine ablation. His hyperglycemia was better control led after treatment of his hyperthyroidism. PM is an autoimmune manifestation of Graves' disease. Almost all cases of thyroid dermopathy are associated with relatively severe ophthalmopathy. Usually ophthalmopathy appears first and dermopathy much later. However, this case represents a rare initial presentation of Graves' disease with PM without ophthalmologic symptoms or findings. Hyperthyroidism is typically associated with worsening glycemic control and increased insulin requirements. In patients with diabetes having hyperthyroidism, deterioration in glycemic control should be anticipated and treatment should be adjusted accordingly

    Pancytopenia can rarely complicate Grave's disease. It can be due to uncontrolled thyrotoxicosis or as a result of rare side effect of antithyroid medication. Pernicious anemia leading to Vitamin B12 deficiency is another rare associated cause. We report a case of a patient with Grave's disease and undiagnosed pernicious anemia whom was assumed to have antithyroid drug induced pancytopenia. Failure to recognize this rare association of pernicious anemia as a cause of pancytopenia had resulted in delay in treatment and neurological complication in our patient.

    HTLV-I carriers or patients with HTLV-I associated myelopathy (HAM) are prone to immune-mediated inflammatory disorders. We present a 44-year-old female with HAM who developed Graves' disease. She developed severe Graves' ophthalmopathy shortly after [sup 131]I therapy, concurrently with a remarkable increase in TSH-receptor antibody titer. Ophthalmopathy was aggravated in spite of prednisolone therapy and euthyroidism being maintained by thyroxine replacement. Uveitis also developed after [sup 131]I therapy and iridocyclitis finally required trabeculotomy. This case suggests that HAM patients may have a higher risk of immune-mediated Graves' ophthalmopathy after [sup 131]I therapy.(author).

    The variety of clinical presentations of eye changes in patients with Graves' disease (GD) suggests that complex interactions between genetic, environmental, endogenous and local factors influence the severity of Graves' ophthalmopathy (GO). It is thought that the development of GO might be influenced by genetic factors and environmental factors, such as cigarette smoking. At present, however, the role of genetic factors in the development of GO is not known. On the basis of studies with candidate genes and other genetic approaches, several susceptibility loci in GO have been proposed, including immunological genes, human leukocyte antigen (HLA), cytotoxic T-lymphocyte antigen-4 (CTLA-4), regulatory T-cell genes and thyroid-specific genes. This review gives a brief overview of the current range of major susceptibility genes found for GD.

    Radiation-related thyroid dysfunction is a common occurrence in patients with Hodgkin's disease treated with mantle field radiation. Although chemical and clinical hypothyroidism are most commonly seen, Graves' disease has also been described. We have examined the records of 437 surgically staged patients who received mantle field irradiation between April 1969 and December 1980 to ascertain the frequency of manifestations of Graves' disease. Within this group, seven patients developed hyperthyroidism accompanied by ophthalmic findings typical of those seen in Graves' disease. The actuarial risk of developing Graves' disease at 10 years following mantle irradiation for Hodgkin's disease was 3.3% in female patients and 1% in male patients in this study. The observed/expected ratios were 5.9 and 5.1 for female and male patients, respectively. This observed risk significantly exceeded that seen in the general population

    We report a patient with Graves' disease who remained persistently hyperthyroid after a total thyroidectomy and also developed de novo Graves' ophthalmopathy 5 months after surgery. She was subsequently found to have a mature cystic teratoma containing struma ovarii after undergoing a total hysterectomy and salpingo-oophorectomy for an incidental ovarian lesion. It is important to investigate for other causes of primary hyperthyroidism when thyrotoxicosis persists after total thyroidectomy.TSH receptor antibody may persist after total thyroidectomy and may potentially contribute to the development of de novo Graves' ophthalmopathy.

    Objective: To explore the anatomy and imaging manifestations of thyroid arteries for improving the efficiency and lowering the complication in interventional embolization of Graves' disease. Methods: Thyroid arteries were investigated, including 16 adult cadavers (Cadaver group), 8 non-thyropathic patients (Normal group)and 17 Graves patients (Graves group). The inner diameters of the trunk and supplying branches of thyroid artery, the angles between the origination of branches and the beginning of the trunk, and the angles between the trunk of thyroid artery and carotid or subclavian artery were measured. In addition, data of the three groups were statistically analyzed. Results: Many non-thyroid arterial branches arose from thyroid artery, with no statistical difference in their indexes between Cadaver group and Normal group. The thyroid arteries showed much longer, obviously wider in diameter, and larger angles between the trunk of thyroid artery and carotid artery in Graves group than those of Cadaver group and Normal group; outcoming with significant statistical differences; and furthermore, with increase of interglandular branches and dangerous internal and external anastomoses. Conclusions: The specific thyroid arterial changes of Graves' disease are helpful for the interventional embolization. Non-thyroid branches and dangerous anastomoses should not be embolized as far as possible, for decreasing the complications of the interventional procedure for Graves' disease. (authors)

    We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p 286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

    Objective: To explore the clinical significance of changes of serum TRAb levels in patients with relapsing Graves' disease. Methods: Serum TRAb (with RRA) and several other thyroid-related hormones (TT 4 , TT 3 , TSH, FT 3 , with CLIA) were determined in the following subjects: 1. 25 cases of relapsing Graves' disease after previous successful treatment; 2. 18 cases of recently diagnosed Graves' disease; 3. 31 cases of successfully treated Graves' disease; 4. 15 cases of simple goiter; 5. 10 cases of nodular goiter; 6. 18 cases of hypothyroidism due to Hashimoto disease. Results: Positive rate of TRAb was 76.00% in patients with relapsing Graves' disease and 77.78% in recently diagnosed Graves' disease cases, both being significantly higher than that in all the other sets of patients studied (P<0.01). Conclusion: Determination of serum TRAb levels was helpful for the diagnosis of relapse in Graves' disease

    Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy. Patients with Graves' disease were younger than MNG and thyroid cancer patients (M age  = 42.8 years vs. 55.5 and 51.0 years; p Graves' disease group included a higher proportion of women (p Graves' disease was independently associated with a higher risk of vocal-cord paralysis (odds ratio [OR] = 1.36 [confidence interval (CI) 1.08-1.69]), tracheostomy (OR = 1.35 [CI 1.1-1.67]), postoperative hypocalcemia (OR = 1.65 [CI 1.54-1.77]), and hematoma requiring reoperation (OR = 2.79 [CI 2.16-3.62]) compared to MNG patients. High-volume centers for total thyroidectomy were independently associated with lower risk of postoperative complications, including in patients with Graves' disease. Despite low overall morbidity following total thyroidectomy, Graves' disease patients are at increased risk of postoperative complications, including bleeding, vocal-cord paralysis, tracheostomy, and hypocalcemia. These risks appear

    The purpose of this study was to assess the frequency and sonographic and laboratory characteristics of Graves disease with intrathyroid hypovascularity in Japanese patients and to compare these characteristics in patients with painless thyroiditis. A total of 194 consecutive patients with Graves disease and 21 patients with painless thyroiditis were enrolled. The patients underwent thyroid volume measurement, mean superior thyroid artery peak systolic velocity (PSV) measurement, power Doppler sonography, and proper blood testing to discriminate between Graves disease and painless thyroiditis. Based on the power Doppler sonographic findings, they were divided into 4 groups: from pattern 0 (most hypovascular thyroid) to pattern III (most hypervascular thyroid). Comparisons of multiple thyroid parameters were made among the groups. The prevalence of Graves disease with pattern 0 (n = 27) was 13.9% among the patients with Graves disease. The sonographic and laboratory data for patients with Graves disease and pattern 0 were compared to those of the 21 patients with painless thyroiditis, which typically shows intrathyroid hypovascularity. Free triiodothyronine and thyroxine levels and the superior thyroid artery PSV were significantly lower in patients with Graves disease and pattern 0 than those with patterns I, II, and III (P thyroid volume and thyrotropin receptor antibody level were significantly lower in patients with Graves disease and pattern 0 than those with pattern III. In the comparison between patients with Graves disease and pattern 0 and those with painless thyroiditis and pattern 0, apart from thyrotropin receptor antibody, only the superior thyroid artery PSV was different. Although the clinical features of patients with Graves disease and intrathyroid hypovascularity were similar to those patients with painless thyroiditis, the superior thyroid artery PSV showed a moderate ability to discriminate these patients. © 2014 by the American Institute of

    Recent reports indicate that orbital irradiation for Graves' ophthalmopathy is sometimes beneficial, particularly for dysthyroid optic neuropathy, and is not associated with serious complications. We are aware, however, of four patients who were found to have radiation retinopathy after orbital irradiation for Grave's ophthalmopathy. All four patients have decreased central acuity, and three of the four are legally blind in one or both eyes. Computer reconstruction of the dosimetry, based on computed tomography and beam profiles, shows that errors in dosage calculations and radiotherapy technique probably account for the radiation retinopathy in three of the four patients. Radiotherapy for Graves' ophthalmopathy should be administered only by competent radiotherapists who are experienced in the treatment of this disease. Similar errors in dosage calculations and treatment techniques may account for other reports of radiation retinopathy after reportedly safe dosages

    We saw 24 thyrotoxic Graves' patients with normal thyroidal uptake of technetium-99m pertechnetate ({sup 99m}Tc) out of 201 untreated thyrotoxic Graves' patients seen over 4 years. The clinical and laboratory findings for these patients were studied and analyzed. Thyroid uptake and scintigraphic examinations by means of {sup 99m}Tc, TBII and TSab activity measurement clearly distinguished these patients from other thyrotoxic disorders (destruction-induced thyrotoxicosis and autonomously functioning thyroid lesions). Different from other disorders, these patients had not lower but normal thyroid uptake and also showed diffuse and discrete trapping into the enlarged glands. These patients had significantly smaller goiters, a lower serum thyroid hormone level, and lower TBII and TSab activity, when compared with other high {sup 99m}Tc uptake groups with Graves' disease, and their condition could be easily controlled with small amounts of antithyroid drugs. Our study indicates that thyrotoxic Graves' disease with normal {sup 99m}Tc uptake exists and {sup 99m}Tc uptake study and TBII activity measurement is very useful for the diagnosis. The normal {sup 99m}Tc uptake thyrotoxic Graves' patient might be early stage patients with general Graves' disease and their early discrimination from general Graves' patients is very advantageous for treatment and prognosis.

    Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

    Postoperative hypocalcaemia has been reported to be more common after total thyroidectomy (TT) for Graves' disease than after TT for benign atoxic multinodular goitre (MNG). The reasons for this potential association are not clear. In the present study, the frequency and risk factors of hypocalcaemia after TT for Graves' vs MNG were compared. Between January 1999 and October 2009, patients with first-time surgery for Graves' disease or MNG treated with a TT were included in the study. Postoperative hypocalcaemia was defined by symptoms, calcium levels and treatment with calcium and/or vitamin D analogues during postoperative hospital stay, at discharge, and at the 6-week and 6-month follow-ups. Outcomes were compared with Mann-Whitney, chi(2) and Fishers' exact test where appropriate and by multivariable logistic regression analysis. There were 128 patients with Graves' disease and 81 patients with MNG. Patients with Graves' disease were younger than patients with MNG (median age, 35 vs 51 years, p Graves' disease (p Graves' disease, there was no difference in the overall frequency of biochemical hypocalcaemia, low levels of PTH and/or treatment with calcium and vitamin D.

  12. Magnetic Ghosts: Mineral Magnetic Measurements On Roman and Anglo-saxon Graves

    Science.gov (United States)

    Linford, N.

    The location of inhumations, in the absence of ferrous grave goods, often presents a considerable challenge to archaeological geophysics given the small physical size of the features and the slight contrast between the fill of the grave and the surround- ing subsoil. Even during excavation, the identification of graves may be complicated where site conditions do not favour the preservation of human skeletal remains and often only a subtle soil stain is likely to survive. A recent initiative in the United King- dom has seen the formation of the Buried Organic Matter Decomposition Integrated with Elemental Status (BODIES) research group, to examine the decomposition of organic artefacts in ancient graves with respect to localised changes in pH, redox po- tential and nutrient status. This paper presents initial results from a limited mineral magnetic study of two grave sites in an attempt to ascertain whether the decomposi- tion of organic remains may lead to a detectable magnetic signature within the soil. Results from a series of isothermal, hysteresis and magneto-thermal experiments will be presented together with surface magnetometer and topsoil susceptibility surveys.

  13. Concomitant Graves' disease and Hashimoto's thyroiditis, presenting as primary hypothyroidism.

    Hypothyroidism in patients with Graves\\' disease is usually the result of ablative treatment. We describe a 58 year old man with Graves\\' ophthalmopathy and pre-tibial myxoedema, who presented with spontaneous primary hypothyroidism. Circulating TSH receptor antibody activity was increased, while thyroid microsomal antibody was detectable in titres greater than one in one hundred thousand. It is likely that the TSH receptor antibody of Graves\\' disease was ineffective in stimulating hyperthyroidism because of concomitant thyroid destruction due to Hashimoto\\'s disease. Alternatively, primary hypothyroidism could have resulted from the effects of a circulating TSH receptor blocking antibody.

    Immunoglobulin A (Ig A) nephropathy is the most common form of primary glomerulonephritis. The association of Ig A nephropathy with Grave's disease has not been reported so far. We report a case of 20-year-old female with Grave's disease who presented with edema, facial puffiness, and decreased urine output. She was found to be hypertensive with renal failure and nephrotic range proteinuria. Renal biopsy revealed features of Ig A nephropathy. The patient was treated with oral corticosteroids (1 mg/kg/day). To our knowledge, this is the first case showing association of Grave's disease with Ig A nephropathy.

    2003-05-01

    Full Text Available This autoethnographic story shows the process of tending the graves of family members. In the past, the author reluctantly accompanied her mother on her visits to the family cemetery. Once there, she took on the role of distant observer as her mother took care of the family cemetery plots. When her mother becomes disabled, the author begins to arrange the flowers on the graves. Doing so leads her to examine the meaning of visiting the cemetery, feel and connect with her losses, and consider the customs she wants to be part of her own death. When her mother dies, the next generation of women in the family—the author, her sister, and sister-in-law—take on the role of tending the graves, connected in their love and respect for their mother and their feelings of family and family responsibility. This story examines the meanings of family rituals around death and how they are passed from generation to generation. URN: urn:nbn:de:0114-fqs0302285

    Here we present the case of a 14-yr-old girl who developed thyroid follicular carcinoma accompanied by Graves' disease. She was diagnosed with Graves' disease at 10 yr of age and soon achieved a euthyroid state after starting treatment. When she was 13 yr of age, her hyperthyroidism and goiter worsened despite medical therapy. Multiple nodules were found in her enlarged thyroid gland by ultrasonography. Her serum Tg level seemed within the normal range. She underwent near-total thyroidectomy for control of thyroid function. Histopathological study demonstrated that multiple oxyphilic follicular neoplasms were surrounded by the thyroid tissue compatible with Graves' disease. Capsular invasion was identified in one of the nodules, and thus the histological diagnosis was minimally invasive follicular carcinoma. She did not have signs suggesting metastasis, and has had no relapse for 18 mo after the operation. Although some previous studies showed a high prevalence of thyroid cancer with an aggressive nature in adult patients with Graves' disease, few reports about thyroid cancer accompanied by Graves' disease are available in children. The present case, however, suggests that careful investigation is needed when we detect thyroid nodules or progressive thyroid enlargement, especially in children with Graves' disease.

    From 1977 to 1982, 315 patients suffering from thyrotoxicosis with diffuse and/or nodular goitre or Graves' disease were treated with 131 I. In 246 patients, the results of treatment after 7 months to 5 1/2 years could be evaluated. After a single treatment with 131 I, 72% of the patients with hyperthyroid nodular goitre and 61% of those with diffuse goitre, but only 36% of the patients with Graves' disease showed normal thyroid function. By repeated 131 I treatments - as many as 5 for those with Graves' disease - normal thyroid function could be achieved in nearly all patients examined. Patients with immune thyrotoxicosis, type Graves' disease, showed a high resistance to therapy. A dependence was found between the results of these treatments and previous antithyroidal drug therapy or surgery. The rate of hypothyroidism varied between 4 and 15%. The highest rate of hypothyroidism was observed in operated patients with persistent or recurring thyrotoxicosis. (orig.) [de

  4. Graves hyperthyroidism and pregnancy: a clinical update.

    2010-01-01

    To provide a clinical update on Graves' hyperthyroidism and pregnancy with a focus on treatment with antithyroid drugs. We searched the English-language literature for studies published between 1929 and 2009 related to management of hyperthyroidism in pregnancy. In this review, we discuss differential diagnosis of hyperthyroidism, management, importance of early diagnosis, and importance of achieving proper control to avoid maternal and fetal complications. Diagnosing hyperthyroidism during pregnancy can be challenging because many of the signs and symptoms are similar to normal physiologic changes that occur in pregnancy. Patients with Graves disease require prompt treatment with antithyroid drugs and should undergo frequent monitoring for signs of fetal and maternal hyperthyroidism and hypothyroidism. Rates of maternal and perinatal complications are directly related to control of hyperthyroidism in the mother. Thyroid receptor antibodies should be assessed in all women with hyperthyroidism to help predict and reduce the risk of fetal or neonatal hyperthyroidism or hypothyroidism. The maternal thyroxine level should be kept in the upper third of the reference range or just above normal, using the lowest possible antithyroid drug dosage. Hyperthyroidism may recur in the postpartum period as Graves disease or postpartum thyroiditis; thus, it is prudent to evaluate thyroid function 6 weeks after delivery. Preconception counseling, a multidisciplinary approach to care, and patient education regarding potential maternal and fetal complications that can occur with different types of treatment are important. Preconception counseling and a multifaceted approach to care by the endocrinologist and the obstetric team are imperative for a successful pregnancy in women with Graves hyperthyroidism.

    Although Graves' disease has been recognised for more than 100 years, its physiopathological mechanisms are incompletely understood. Treatment strategies today mainly focus on suppression of thyroid hormone production by use of antithyroid drugs or radio-iodine, but neglect the underlying immunological mechanisms. Although Graves' disease is often seen as a prototype for an autoimmune mechanism, it is more likely to be a heterogeneous syndrome showing characteristics of both autoimmunity and immunodeficiency. The interplay of these two mechanisms may well characterise the physiopathology of this disease and its complications. Immunodeficiency may be either genetically determined or secondarily acquired. Various triggering events lead to autoimmunity with stimulation of the thyroid gland resulting in the clinical syndrome of hyperthyroidism. Also, relapse risk differs from patient to patient and can be estimated from clinical parameters incorporated into the Graves' Recurrent Events After Therapy (GREAT) score. Accurate risk stratification may help to distinguish high-risk patients for whom a more definitive treatment approach should be used from others where there is a high probability that the disease will recover with medical treatment alone. Several smaller trials having found positive effects of immunosuppressive drugs on recurrence risk in Graves' disease; therefoore, there is great potential in the use of novel immunomodulating drugs in addition to the currently used antithyroid drugs for the successful treatment of this condition. Further in-depth exploration of susceptibility, triggering factors and immunological mechanisms has the potential to improve treatment of Graves' disease, with more personalised, risk-adapted treatment strategies based on the different physiopathological concepts of this heterogeneous condition.

    The effect of radiation therapy for Graves` ophthalmopathy was evaluated. Ten patients with Graves` ophthalmopathy were treated with radiation therapy between 1992 and 1993 in Gunma University Hospital. All patients had a past history of hyperthyroidism and received 2,000 cGy to the retrobulbar tissues in 20 fractions. Nine of ten patients were treated with radiation therapy after the failure of corticosteroids. Six patients (60%) showed good or excellent responses. The exophthalmos type was more responsive to radiation therapy than the double vision type in this series. Two of five patients with the exophthalmos type demonstrated excellent responses, and their symptoms disappeared almost completely. The improvement of symptoms appeared within 3-6 months, and obvious clinical effects were demonstrated after 6 months of radiotherapy. Radiation therapy was well tolerated, and we have not observed any side effects of radiation therapy. In conclusion, radiation therapy is effective treatment for Graves` ophthalmopathy. (author)

    Concern about the side effects of radiation exposure has deterred physicians from using radioiodine treatment for Graves' disease, although the efficacy and safety of this treatment have been established in the 35 years since its introduction. In that time, no significant side effects have been discovered. We believe iodine-131 should be considered the treatment of choice in most patients with Graves' disease. This article reviews the current understanding of the risks in radioiodine treatment of Graves' disease, including the risks for teratogenicity, genetic damage, carcinogenesis, and cellular dysfunction

    Treatment options in Graves' disease are clearly defined, but management practices and the perceptions of success are varied. The outcomes of treatment in large consecutive cohorts of Graves' disease have not been well characterised. The study describes the epidemiology, management strategies and medium term outcomes following anti-thyroid drug treatment, radio-iodine ablation and surgery in Graves' disease. All patients (n = 659) who received treatment for a new diagnosis of Graves' disease in secondary care over a 5 year period were included with a median (interquartile range) follow-up of 42.9 (29-57.5) months. The age adjusted incidence of adult onset Graves' disease in Sheffield, UK was 24.8 per 100,000 per year. Excluding 35 patients lost to follow-up, 93.1% (n = 581) were controlled on anti-thyroid drug treatment. Of these, 73.6% went into remission following withdrawal of anti-thyroid drugs; 5.2% were still undergoing initial therapy; 13.3% lost control whilst on anti-thyroid drugs; and 7.9% went on to have either surgery or radio-iodine ablation whilst controlled on anti-thyroid drugs. Of the 428 patients who achieved remission, 36.7% relapsed. Of 144 patients who had radio-iodine ablation treatment, 5.6% relapsed and needed further treatment. Of 119 patients having surgery, 5.2% had long-term hypoparathyroidism and none had documented long-term recurrent laryngeal nerve palsy. In the follow-up, 39.9% of patients underwent surgery or radio-iodine ablation with little morbidity. Up to two-thirds of patients who achieved remission did not relapse. Data on effectiveness and risks of treatments for Graves' disease presented in this study will help clinicians and patients in decision making.

    This study evaluates F-18-FDG PET of the thyroid in Graves' disease. Methods: Thirty patients were investigated the day before radioiodine therapy, 15 patients 3-10 days after radioiodine therapy. Twenty patients with cancer of the head or neck and normal thyroid function served as controls. Results: F-18-FDG uptake was higher in Graves' disease patients than in controls. Negative correlations of F-18-FDG uptake with half-life of radioiodine and absorbed radiation dose due to radioiodine therapy were found along with a positive correlation to autoantibody levels. Conclusion: Thus F-18-FDG PET is likely to give information on the biological activity of Graves' disease as well as on early radiation effects. (orig.) [de

    Graves' disease is an autoimmune disorder in which autoantibodies to the thyroid-stimulating hormone receptor cause hyperthyroidism through unregulated stimulation of the thyroid-stimulating hormone receptor. Effective management of Graves' disease in pregnancy must address the competing fetal and maternal priorities of controlling hyperthyroidism in the mother on the one hand, and on the other, minimizing the impact of maternal disease and antithyroid drugs on the well-being of the fetus. Optimal strategies for achieving this intricate balance are currently a source of continued debate among thyroid experts and studies in recent decades are now providing greater clarity into the risk posed to the unborn baby by the combination of biochemical, immunological and pharmacological hazards arising from Graves' disease and its therapy. This review summarizes the current best practice and highlights important considerations and areas of uncertainty in the management of Graves' disease in pregnant women.

    Lithium is known to cause goiter and hypothyroidism. In the mechanism of goitrogenesis, there is general agreement that lithium inhibits the release of the thyroid hormones from the thyroid gland without significantly impairing other thyroid functions. The present study was undertaken, therefore, to investigate the usefulness of lithium in the radioiodine treatment of Graves' disease. Nine patients with Graves' disease who were all, except one, previously treated with antithyroid drugs were studied. 600 mg of lithium carbonate were administered daily to investigate the effects on thyroidal 131 I uptake, disappearance rate of 131 I from the prelabeled thyroid and the serum concentrations of thyroid hormones. Lithium showed no significant effect on the thyroidal 131 I uptake when the 24 hour thyroidal 131 I uptakes were determined both before and during lithium treatment in the five cases. On the other hand, lithium clearly prolonged the mean value of effective half-lives of 131 I to approximately 8 days vs. 5.1 days before lithium treatment (p 4 and T 3 levels significantly decreased during lithium treatment, from 21.3 to 12.4μg/dl (n=9, p 131 I for the Graves' disease can be reduced by using lithium, the radiation exposure to the total body is decreased. Moreover, it is possible to perform the 131 I therapy while improving the thyrotoxicosis with lithium. Finally, it is concluded that lithium is a very useful drug to be combined with the 131 I therapy of Graves' disease. (author)

    Thyroid ophthalmopathy is a complication most commonly associated with Grave's disease. The disease course ranges from mild to severe, with severe cases resulting in major visual impairment. A complete ophthalmic examination in a 35-year-old secundigravida to 14 weeks of gestation presented to the hospital for a routine ophthalmological examination with eyelid retraction in the right eye was made. We studied the course of ocular disease through the gestation with orbit ecography and a 3T MRI. A diagnosis of Grave's Ophthalmopathy was made. This case presents an unusual course of the GD during pregnancy and a normal post-partum relapse, according to the Th1/Th2 balance. The frequent follow-up and the use of MRI allowed a prompt identification and complete control of the disease.

    Full Text Available El mal agudo de montaña (MAM es un conjunto de síntomas inespecíficos padecidos por sujetos que ascienden rápidamente desde baja a alta altura sin adecuada aclimatación. Usualmente es autolimitado, pero las formas graves (edema pulmonar y cerebral pueden causar la muerte. La hipoxemia exagerada en reposo está relacionada con el desarrollo de MAM pero su valor predictivo es limitado. Dado que el ejercicio en altura se acompaña de mayor hipoxemia y síntomas, postulamos el valor predictivo de un simple test de ejercicio para pronosticar MAM grave. Se estudió el valor predictivo de la saturación de oxígeno en reposo y ejercicio submáximo a 2.700 m y 4 300 m en 63 sujetos que ascendían al cerro Aconcagua (6 962 m. Se consideró desaturación de oxígeno con ejercicio a una disminución = 5% respecto al reposo. Se utilizó la escala de Lake-Louise para establecer la presencia de MAM grave. Seis sujetos presentaron MAM grave (9.5% y requirieron evacuación. La saturación de oxígeno en reposo a 2.700 m no fue significativa para clasificar sujetos que luego desarrollaron MAM grave. Por el contrario, la asociación de desaturación durante el ejercicio a 2.700 m más la saturación inapropiada en reposo a 4.300 m fue significativa para clasificar a los sujetos que desarrollaron MAM grave con un valor predictivo positivo de 80% y un valor predictivo negativo del 97%. Nuestros resultados son relevantes para el montañismo y sugieren la adición de un simple test de ejercicio en la predicción del MAM grave.Acute mountain sickness (AMS is a group of non-specific symptoms, seen in subjects that ascend from low to high altitude too quickly, without allowing sufficient time to acclimatize.

    Airway complications rarely occur in 131 I radioiodine therapy for Graves' disease. This study presents two cases in which 131 I therapy caused this acute complication. The patients complained of the symptom 6 h and 33 h after administration of 131 I. A histamine H1 receptor antagonist and hydrocortisone rapidly resolved symptoms in both cases. These two cases remind physicians that 131 I therapy for Graves' disease may cause potentially life-threatening complications. (author)

    In order to study the role of LATS in the pathogenesis of the Graves' disease, the serum activity of the LATS was determined by the bioassay of the modified McKenzie method. The subjects examined in the study consisted of 76 individuals including 12 cases of normal control, 54 cases with typical Graves' disease and 10 cases of chronic thyroiditis. The data observed in the patients with the Graves' disease were analyzed in comparison with the clinical features, laboratory findings, and responsiveness to the treatment. The results obtained are as follows: 1) None of the subjects which did not have the Graves' disease showed a positive LATS activity, except one case with the chronic thyroiditis. 2) Twenty-two oui of the 54 cases with the Graves' disease showed positive results for LATS (40.7%). The positivity was significantly higher in the patients who had been treated with antithyroid regimen but still showed hyperthyroidism than in the patients who had not been treated. 3) The activity of LATS was gradually decreased or even became absent as the hyperthyroidism was corrected after the treatment. 4) No significant difference was noticed in age and-sex between the positive and negative groups of LATS. 5) There was no evidence of significant correlation between the LATS activity and clinical features.

    2005-10-01

    Full Text Available In many polycrystalline ceramic materials, the main phase coexists with a secondary phase, generally glassy in nature. The existence of this phase is associated to the use of certain sintering additives. In a general sense, the secondary phase is located at “pockets” between various grains, or it is distributed as a thin film at the grain boundaries. From the viewpoint of the creep behaviour at high temperatures, the secondary glassy phase plays a triple role: firstly, the secondary phase may flow under the applied stress. Secondly, the grain boundaries occupied by the secondary phase constitute high-diffusivity trajectories, even at temperatures lower than those required for bulk diffusion. Finally, the regions with secondary phase are preferential locations for the nucleation of cavities. In this work, the deformation mechanisms characteristic of ceramic polycrystals with secondary glassy phases (viscous flow, solution-precipitation and cavitation creep, which are related to the triple role played by these phases. Particularly, the most significant models for each mechanism are presented, as well as a comparative with experimental results obtained in different materials.

    En un gran número de materiales cerámicos policristalinos, la fase mayoritaria coexiste con una fase secundaria, generalmente de naturaleza vítrea. La existencia de esta fase se debe al uso de determinados aditivos durante la sinterización. En general, la fase secundaria se acumula en “bolsas” entre varios granos, o bien se distribuye en forma de película delgada en las fronteras de grano. Desde el punto de vista de la fluencia a alta temperatura, la fase secundaria desempeña un triple papel: en primer lugar, esta fase puede fluir bajo la acción de la tensión aplicada. Por otra parte, las fronteras de grano ocupadas por la fase secundaria constituyen trayectorias de alta difusividad, incluso a temperaturas menores que las requeridas para la difusión por

    No consensus exists on optimal treatment for Graves' disease once anti-thyroid medication fails to induce remission. Total thyroidectomy is a more cost-effective treatment than radioactive iodine or life-long anti-thyroid medication, but hypocalcaemia is an important complication, leading to longer hospital admissions and increased prescription costs. This study aimed to compare the relative risk of hypocalcaemia requiring medical treatment for patients with Graves' disease. Prospective cohort study of patients undergoing total thyroidectomy for Graves' disease and for multinodular goitre, calculating serum calcium levels 24-hours post-operatively and prescription rates. Mean corrected calcium concentrations 24 hours post-operatively were 2.05 mmol/l for Graves' disease patients and 2.14 mmol/l for multinodular goitre patients (p = 0.003). Biochemical hypocalcaemia developed in 92 per cent (n = 34) of Graves' disease patients and 71 per cent (n = 43) of multinodular goitre patients (p = 0.012). Graves' disease patients were more likely to be prescribed calcium supplementation pre-discharge (p = 0.037). Total thyroidectomy for Graves' disease carries an increased risk of hypocalcaemia at 24 hours, and of calcium supplementation pre-discharge. Graves' disease patients should be informed of the increased risk of hypocalcaemia associated with total thyroidectomy, and this risk must be factored into future cost-effectiveness analysis.

This research shows the predicted secondary structure of protein from its primary amino acid sequence using Support Vector Machines. As inputs, in the proposed methodology, features are used from different structural motifs or text strings associated with the primary structure which represents the secondary structure, such as R-group and the probability that the amino acid at position adopts a central particular secondary structure. For feature extraction method is used coding of sequences in which each symbol in the primary structure is associated with each symbol in the secondary structure. The use of this encoding method reduces the dimensionality of the data of thousands of characteristics only 220 of these. The results obtained are comparable to those reported in the literature, taking about 70% accuracy. Furthermore, it is possible to reduce computational cost in the construction of classifiers because this work models the problem of multi classification as a group of binary classifiers.

    2002-01-01

    At the 15th conference on the human thyroid in Heidelberg in 2001 the following aspects of the radioiodine therapy of benign thyroid disorders were presented: General strategies for therapy of benign thyroid diseases, criterions for conservative or definitive treatment of hyperthyroidism as first line therapy and finally preparation, procedural details, results, side effects, costs and follow-up care of radioiodine therapy as well as legal guidelines for hospitalization in Germany. The diagnosis Graves' hyperthyroidism needs the decision, if rather a conservative treatment or if primary radioiodine therapy is the best therapeutic approach. In the USA 70-90% of these patients are treated with radioiodine as first line therapy, whereas in Germany the conservative therapy for 1-1.5 years is recommended for 90%. This review describes subgroups of patients with Graves' disease showing a higher probability to relapse after conservative treatment. Comparing benefits, adverse effects, costs, and conveniences of both treatment strategies the authors conclude that radioiodine therapy should be preferred as first line therapy in 60-70% of the patients with Graves' hyperthyroidism.

The study group comprised of 561 Polish Caucasians, including 172 unrelated Graves' disease patients. CTLA-4c.49A>G, CTLA-4g.319C>T, and CT60 were genotyped by PCR-RFLP; Jo31 and CD28c.17+3C>T by minisequencing; CTLA-4g.*642AT(8_33) and ICOSc.1554+4GT(8_15)-PCR and fluorescence-based technique.

TCG(AT 16-21 )GG(l) haplotype increased risk of Graves' disease and reduced the chance of successful medical treatment. Although this haplotype was mainly observed in patients without signs of Graves' orbitopathy, if Graves' orbitopathy developed it favored a Graves' orbitopathy outcome. Haplotype TCA(AT >21 )GT(m) increased Graves' disease risk in women and, in all patients, was linked to Graves' disease without Graves' orbitopathy. TCG(AT Graves' disease risk factor, whereas CT60 was an independent factor for disease progression. Sporadic Graves' disease was related to presence of CTLA-4c.49A>G[A] and the rare CTLA-4g.319C>T[T] allele variant. Familial background of the disease was exclusively associated with CTLA-4g.*642AT(8_33)[AT >21 ]/[AT >21 ] genotype.

    Hyperthyroidism, or thyrotoxicosis, results when the body's tissues are exposed to excessive levels of thyroid hormone. Hyperthyroidism affects 2% of women but only one-tenth as many men. Graves' disease is the most common form of hyperthyroidism, often occurring in young adults. It is an autoimmune disorder with an important genetic component. Hyperthyroidism's hallmarks include goiter and myriad signs and symptoms related to increased metabolic activity in virtually all body tissues. Increased sensitivity to circulating catecholamines adds to the clinical picture. Diagnosed by patient history, physical examination, and laboratory tests, Graves' disease is treated with antithyroid drugs, radioactive iodine, and/or surgery, plus supportive therapy. A good treatment outcome can be expected; long-term follow-up is indicated.

    Medical treatment of Graves' hyperthyroidism is based on the use of thionamides; namely, methimazole and propylthiouracil. In the past, methimazole was preferred by European endocrinologists, whereas propylthiouracil was the first choice for the majority of their North American colleagues. However, because of the recent definition of a better side-effect profile, methimazole is nowadays the first choice world while. Although thionamides are quite effective for the short-term control of Graves' hyperthyroidism, a relatively high proportion of patients relapses after thionamide withdrawal. Other possible medical treatments, include iodine and compounds containing iodine, perchlorate, lithium (as an adjuvant in patients undergoing radioiodine therapy), β-adrenergic antagonists, glucocorticoids, and some new molecules still under investigation. Management of Graves' hyperthyroidism using thionamides as well as the other available medical treatments is here reviewed in detail, with a special mention of situations such as pregnancy and lactation, as well as neonatal and fetal thyrotoxicosis.

    Full Text Available Introducción: la mayoría de los adolescentes usa Internet sin que esto repercuta en su salud; sin embargo, algunos pueden presentar pérdida de control sobre la manera en la que utilizan este medio, lo que conlleva a un uso problemático que puede derivar en adicción. Objetivo: identificar los tipos de uso de Internet en estudiantes de secundaria y bachillerato, sus posibles causas y su relación con la impulsividad. Método: se realizó un estudio observacional, transversal, analítico y ex post facto en una muestra estratificada de 123 estudiantes de secundaria y 125 de bachillerato, de entre 12 y 18 años de edad, inscritos en dos escuelas de Xalapa, Veracruz, México; se utilizó la prueba de Adicción a Internet de Young en español. Resultados: 83% de los estudiantes presentó control sobre el uso de Internet, 17% mostró un uso problemático y no se encontró adicción a la red. El uso problemático fue mayor entre los estudiantes de secundaria (23%, que entre los de bachillerato (10%. La impulsividad no fue estadísticamente significativa para presentar un uso problemático, pero sí lo fueron indicadores como estar conectado más de seis horas y el empleo exclusivo de Internet para consultar y relacionarse en las redes sociales. Discusión y conclusiones: no se encontró una relación significativa entre impulsividad y uso problemático de Internet; sin embargo, los factores de exposición pueden explicar que el individuo disminuya el contacto con su entorno familiar y social. Los hallazgos de este trabajo pueden constituir una guía para futuras líneas de investigación que profundicen en el conocimiento de este problema.

    Overt neonatal Graves' disease is rare, but may be severe, even life threatening, with deleterious effects on neural development. The main objective of this study was to describe the course of thyrotropin (TSH) and free thyroxin (fT4) levels, as well as postnatal weight gain in relation to fT4 levels, in neonates born to women with Graves' disease without overt neonatal thyrotoxicosis. Such information is important to deduce the optimal schedule for evaluation. We conducted a retrospective chart review of neonates born to mothers with Graves' disease between January 2007 and December 2012. The records were reviewed for sex, gestational age, birth weight, maternal treatment during pregnancy, and maternal thyroid stimulating immunoglobulin (TSI) level. For each visit in the clinic, the data included growth parameters, presence of symptoms suspected for hyperthyroidism, blood test results (levels of TSH, fT4, and TSI), and treatment. Ninety-six neonates were included in the study (49 males), with a total of 320 measurements of thyroid function tests (TSH and fT4). Four neonates (4%) had overt neonatal Graves' disease; one of them along with nine others were born preterm. In 77 (92.9%) of the remaining 83 neonates (the subclinical group), fT4 levels were above the 95th percentile on day 5. All had normal fT4 on day 15. A negative association was found between fT4 and weight gain during the first two weeks. In this cohort, most neonates born to mothers with Graves' disease had a subclinical course with abnormal fT4 levels that peaked at day 5. After day 14, all measurements of fT4 returned to the normal range, although measurements of TSH remained suppressed for up to three months. Elevated fT4 was associated with poor weight gain.

    Full Text Available En este artículo se señala la utilidad de la investigación histórico-educativa para identificar la etiología y analizar el desarrollo de las problemáticas que afectan al sistema educativo. A lo largo del siglo XIX y la mayor parte del XX, la formación inicial del profesorado de Secundaria estuvo definida por la episteme y por un estilo docente de carácter universitario. Sin embargo, la universalización de la Enseñanza Secundaria y los retos derivados del Proyecto DeSeCo, en el que se definen las Competencias Básicas que deben adquirir los alumnos en la educación obligatoria, reclaman nuevas funciones y capacidades al profesorado de Educación Secundaria. Tras este análisis y a la luz del estudio de algunos trabajos recientes, como conclusión proponemos un perfil competencial del nuevo docente de Secundaria, articulado en torno a los cuatro pilares fundamentales para la educación del siglo XXI: saber, saber hacer, saber convivir y saber ser.

    Grave's disease is an autoimmune disease of the thyroid gland characterized by hyperthyroidism, a homogenous goiter and occasionally an ophtalmopathy. It occurs in less than 1% of the population with a large predominance in women (10/1). Treatment is directed to inhibit thyroid hormone synthesis with carbimazole during 12-18 months. Recurrence rates after stopping treatment is about 50%; in these patients, radioactive iodine is the preferred treatment.

    To make a preliminary quality control (QC) criteria and apply on the various stages of clinic 131 I treatment of Graves' disease in order to decrease the early happening of hypothyroidism and enhance the onetime 131 I cure rate of Graves' disease, the quality control criteria in the stochastic outpatient with 131 I treatment, such as plan of the indication, contraindication, method of treatment, matters needing attention, follow-up observation and curative effect appraisal, patient selection, RAIU, thyroid gland weight measurement and 131 I dose criteria for the various steps of 131 I medication were determined. The 131 I treatment effects of Graves' disease including the once-cure rate, the improving rate, duplicate cure rate and the early happening rate of hypothyroidism were analyzed in patients with applying QC and without QC ccriteria. The results showed that the oncecure rate in patients with applying QC criteria was increased from 76.6% to 90.9% (P≤0.01); the improving rate was decreased from 12.2% to 7.0% (P≤0.01); the duplicate cure rate was increased from 90.1% to 93.0% (P>0.05); the early happening rate of hypothyroidism was decreased from 11.0% to 2.1% (P≤0.01). The 131 I treatment of Graves' disease applying with QC criteria had tremendously improved the oncecure rate and decreased the early happening of hypothyroidism rate. (authors)

En primer lugar, se presentan las variables psicológicas y sociodemográficas del agresor y de la víctima, así como de la relación de pareja. Y en segundo lugar, se determinan las diferencias más significativas entre la violencia grave y la violencia menos grave en relación con esas mismas variables. Los resultados ponen de manifiesto que tanto los agresores como las víctimas tienden a ser jóvenes, con una sobrerrepresentación de agresores y víctimas extranjeros inmigrantes. En el caso de los maltratadores graves, tienden a ser celosos o posesivos, a sentirse humillados por la ruptura de la pareja, lo que redunda directamente en un descenso de su autoestima y a consumir abusivamente alcohol o drogas. Por lo que se refiere a las víctimas de la violencia grave, se suelen sentir con frecuencia en peligro de muerte y están más fácilmente en circunstancias de vulnerabilidad, como una edad muy joven, una personalidad muy dependiente, una situación de enfermedad crónica o de dependencia económica, un consumo de drogas o un entorno de soledad. Se comentan las implicaciones de este estudio para la investigación y para la práctica clínica.

    Generally, clinical presentations of Graves' disease range from asymptomatic disease to overt symptomatic hyperthyroidism with heat intolerance, tremor, palpitation, weight loss, and increased appetite. However, atypical presentation of Graves' disease with hematological system involvement, notably pancytopenia, is distinctly uncommon. Hereby, we present and discuss a series of three untreated cases of Graves' disease clinically presented with pancytopenia and the hematological abnormalities that responded well to anti-thyroid treatment. With resolution of the thyrotoxic state, the hematological parameters improved simultaneously. Thus, it is crucial that anti-thyroid treatment be considered in patients with Graves' disease and pancytopenia after a thorough hematological evaluation.

    1982-01-01

    Thirteen patients with varying degrees of Graves' ophthalmopathy were examined using high-resolution infrared oculography to determine peak velocities for horizontal eye movements between 3 degrees and 30 degrees. As severity of the orbital disease increased, peak velocities became substantially lower. Vertical-muscle surgery failed to have any effect on peak velocity of horizontal eye movements. In contrast, orbital decompression caused notable improvement in peak velocity of eye movements. Eye-movement recordings, which provide a measure of extraocular muscle function rather than structure, may provide a safe, sensitive, and accurate method for classifying and following up patients with Graves' ophthalmopathy

    Full Text Available Graves' disease is a common condition and is known to have a wide range of effects on a variety of organs. Hepatic dysfunction ranging from mild to severe due to direct effect of high circulating thyroid hormones as well as a deleterious effect of antithyroid medications (methimazole and propylthiouracil has been well - documented in literature. However, severe autoimmune hepatitis (AIH associated with Graves' disease is rare and limited to few case reports only. A 38-year-old woman presented with abdominal pain and yellowish discolouration of conjunctivae. On investigation, she was found to have Graves' disease and AIH. The liver histopathology showed typical features of AIH. She responded excellently to glucocorticoid therapy with normalisation of thyroid function and liver histology.

    In Graves' disease, because a thyroid tends to have extreme vascularity, the amount of intraoperative blood loss (AIOBL) becomes significant in some cases. We sought to elucidate the predictive factors of the AIOBL. A total of 197 patients underwent thyroidectomy for Graves' disease between 2002 and 2012. We evaluated clinical factors that would be potentially related to AIOBL retrospectively. The median period between disease onset and surgery was 16 months (range: 1-480 months). Conventional surgery was performed in 125 patients, whereas video-assisted surgery was performed in 72 patients. Subtotal and near-total/total thyroidectomies were performed in 137 patients and 60 patients, respectively. The median weight of the thyroid was 45 g (range: 7.3-480.0 g). Univariate analysis revealed that the strongest correlation of AIOBL was noted with the weight of thyroid (p Graves' disease, and preparation for blood transfusion should be considered in cases where thyroids weigh more than 200 g.

    Graves' disease has been associated with an increased psychiatric morbidity. It is unclarified whether this relates to Graves' disease or chronic disease per se. The aim of our study was to estimate the prevalence of anxiety and depression symptoms in patients with Graves' disease compared to patients with another chronic thyroid disease, nodular goitre, and to investigate determinants of anxiety and depression in Graves' disease. 157 cross-sectionally sampled patients with Graves' disease, 17 newly diagnosed, 140 treated, and 251 controls with nodular goitre completed the Hospital Anxiety and Depression Scale (HADS). The differences in the mean HADS scores between the groups were analysed using multiple linear regression, controlling for socio-demographic variables. HADS scores were also analysed dichotomized: a score >10 indicating probable 'anxiety'/probable 'depression'. Determinants of anxiety and depression symptoms in Graves' disease were examined using multiple linear regression. In Graves' disease levels of anxiety (p = 0.008) and depression (p = 0.014) were significantly higher than in controls. The prevalence of depression was 10% in Graves' disease versus 4% in nodular goitre (p = 0.038), anxiety was 18 versus 13% (p = 0.131). Symptoms of anxiety (p = 0.04) and depression (p = 0.01) increased with comorbidity. Anxiety symptoms increased with duration of Graves' disease (p = 0.04). Neither thyroid function nor autoantibody levels were associated with anxiety and depression symptoms. Anxiety and depression symptoms were more severe in Graves' disease than in nodular goitre. Symptoms were positively correlated to comorbidity and duration of Graves' disease but neither to thyroid function nor thyroid autoimmunity.

    Graves' ophthalmopthy is one of the most common causes of exophthalmos as well as the most common manifestation of Graves' disease. The treatment of Graves' ophthalmopathy includes ophthalmological and endocrinological therapy. The aim of this study was to clinically evaluate the patients with Graves' ophthalmopathy treated with corticosteroids. Evaluation of 21 patients was performed in the Ophthalmology Clinic and Endocrinology Clinic, Clinical Centre Kragujevac, in the period from 2009 to 2010. They were treated with pulse doses of intravenous corticosteroids. They were referred to ophthalmologist by endocrinologist in euthyroid condition in the active phase of Graves' ophthalmopathy (ultrasonography of orbit findings and positive findings of antithyroid stimulating hormone receptor antibody--anti-TSH R Ab). The clinical activity score (CAS) and NO SPECS classification for evaluation of disease severity were used. Ophthalmological examination includes: best corrected visual acuity, slit-lamp exam, Hertels' test, direct ophthalmoscopy and ultrasonography of the orbit. According to our results 76.19% of the patients were female; mean age of the patients was 35.2 +/- 5.6 years. According to CAS classification after 6 months of the treatment recovery was shown in 23.81% of the patients, partial amelioration in 47.62% and no clinical amelioration in 28.57% of the patients. We achieved better results with male, young patients with high clinical activity score. Good results were observed after the first dose of corticosteroids, much better CAS after the third dose, which maintained until 6 months after the first treatment. Our results signify that intravenous pulse dose of corticosteroids treatment of the patients with Graves' ophthalmopthy is safe, comfortable, clinically justified and accessible for the clinicians and patients. Positive results are achieved after the first dose with increasing trend up to the third dose, which was maintained for the next three months.

    Full Text Available Graves' disease, the main cause of hyperthyroidism in the pediatric age group, is very rare in children younger than 4 years old but can seriously interfere with growth and development if not recognized and treated. Here we report a case of a 3-year-old girl with Graves' disease who presented with goiter, exophthalmos, heat intolerance, and hyperactivity. At her first visit, her serum concentrations of triiodothyronine (T3 and free thyroxine (free T4 were normal, whereas that of thyroid-stimulating hormone (TSH was decreased. Antimicrosomal antibody was 7,053.94 IU/mL, and TSH-binding inhibitory immunoglobulin was 31.62%. A thyroid scan showed diffuse enlargement with markedly increased uptake of both thyroid glands. Although T3 and free T4 levels were initially normal, she developed hyperthyroidism 3 months later. She was finally diagnosed with Graves' disease and treated with methimazole for 6 months. This is the first report of Graves' disease in children younger than 4 years old in Korea.

    Graves' orbitopathy, a condition seen in the autoimmune syndrome Graves' disease, affects the fatty tissue and muscles inside the orbit. Graves' orbitopathy is associated with increasing exophthalmos and sometimes leads to compressive dysthyroid optic neuropathy, resulting in progressive vision loss. Dysthyroid compressive optic neuropathy, functional problems, and cosmetic problems are the main indications for surgical decompression of the orbit, especially if conservative treatment has not led to a reduction in symptoms. Many surgical techniques are described in the literature. This article presents a modification of the lateral orbital wall osteotomy, involving the rotation and reduction of the osteotomized bone segment using preoperative planning, intraoperative computed navigation, and piezoelectric surgery. This new method combines the advantages of different techniques and appears to be a valid approach to the treatment of severe cases of Graves' orbitopathy.

    We studied the effects of radioiodine therapy (RIT) for autonomously functioning thyroid nodules (AFTNs) and Graves' disease on thyroid function and size up to one year after RIT. In 230 patients with AFTNs, a dose of 300 Gy was effective in about 90% of the cases 6 months after RIT. Out of 65 patients suffering from Graves' disease, 5 patients (8%) had persisting hyperthyroidism 6 months after RIT with a dose of 150 Gy. This group consisted exclusively of patients with manifest hyperthyroidism at the time of RIT. As determined by ultrasonography 6 months after RIT, a reduction of thyroid size by about 40% and 60% was observed in patients with AFTNs and Graves' disease, respectively. (orig.) [de

    Graves' disease is the most common cause of hyperthyroidism. Both antithyroid medications and radioiodine are commonly used treatments but their frequency of use varies between regions and countries. Despite the commonness of the diagnosis, any possible differences between the two treatments with respect to long-term outcomes remain unknown. To assess the effects of radioiodine therapy versus antithyroid medications for Graves' disease. We performed a systematic literature search in the Cochrane Library, MEDLINE and EMBASE and the trials registers ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was September 2015 for all databases. Randomised controlled trials (RCTs) comparing the effects of radioiodine therapy versus antithyroid medications for Graves' disease with at least two years follow-up. Two authors independently screened titles and abstracts for relevance. One author carried out screening for inclusion, data extraction and 'Risk of bias' assessment and a second author checked this. We presented data not suitable for meta-analysis as descriptive data. We analysed the overall quality of evidence utilising the GRADE instrument. We included two RCTs involving 425 adult participants with Graves' disease in this review. Altogether 204 participants were randomised to radioiodine therapy and 221 to methimazole therapy. A single dose of radioiodine was administered. The duration of methimazole medication was 18 months. The period of follow-up was at least two years, depending on the outcome measured. For most outcome measures risk of bias was low; for the outcomes health-related quality of life as well as development and worsening of Graves' ophthalmopathy risks of performance bias and detection bias were high in at least one of the two RCTs.Health-related quality of life appeared to be similar in the radioiodine and methimazole treatment groups, however no quantitative data were reported (425 participants; 2 trials; low quality evidence

    Thyrotoxicosis, most often caused by Graves' disease (GD), when treated inadequately may result in premature mortality. There is little consensus as to which of the 3 treatment options available - antithyroid drugs (ATD), radioactive iodine (RAI) and surgery, is better. (i) To assess factors involved in treatment choice and treatment satisfaction in patients treated for Graves' disease; (ii) To assess quality of life (QoL) following treatment of Graves' disease. Participants were selected from a prospective study cohort assessing thyrotoxicosis incidence and severity. Of the 172 eligible patients with Graves' disease, 123 treated patients participated (64% had received ATD only, 11% RAI and 25% total thyroidectomy, the latter 2 usually after a period of ATD), along with 18 untreated patients with newly diagnosed Graves' disease (overall participation rate, 73%). Consented patients completed a questionnaire detailing factors involved in treatment choice, QoL and satisfaction with treatment. Participants reported that the most important factors in choosing a treatment were the following: the effects on activities of daily living, concern about use of radioiodine, possibility of depression or anxiety, and doctor's recommendations. Satisfaction levels were high across all 3 treatment types. QoL 1-year following treatment was higher than in untreated patients, and comparable with other international studies. Patient satisfaction with therapy and QoL does not differ by treatment type. Therefore, clinical and social factors, in combination with patient choice and resource availability, should determine which treatment modality patients with Graves' disease should receive. © 2018 John Wiley & Sons Ltd.

    Radioiodine[131I] has been used for the treatment of Graves' hyperthyroidism since the late 1940's and is now generally regarded as the treatment of choice for Graves' hyperthyroidism who does not remit following a course of antithyroid drugs. But for the dose given, several different protocols have been described by different centers, each attempting to reduce the incidence of long-term hypothyroidism while maintaining an acceptable rate control of Graves' hyperthyroidism. Our goals were to evaluate effective half-life and predict absorbed dose in Graves' hyperthyroidism patients, therefore, to calculate and read minister radioiodine activity needed to achieve aimed radiation dose. Our data showed that the mean effective 131I half-life for Graves' disease is 5.3 days(S.D=0.88) and mean biologic half-life is 21 days, range 9.5-67.2 days. The mean administered activity and the mean values of absorbed doses wet: 532 MBq(S.D.=254), 112 Gy (S.D.=50.9), respectively. The mean activity needed to achieve aimed radiation dose were 51 MBq and marked differences of 131I thyroidal uptake between tracer and therapy occurred in our study. We are sure that the dose calculation method that uses 5 days thyroidal 131I uptake measurements after tracer and therapy dose, provides sufficient data about the effective treatment in Graves' hyperthyroidism.

    We present a rare case of chylothorax associated with an intrathoracic goiter in Graves' disease that was treated with radioactive iodine. A 23-year-old woman with Graves' disease was referred to our clinic with a pleural effusion, dyspnea, characteristic bilateral proptosis, and a diffuse goiter. The pleural fluid biochemistry was consistent with chylothorax. However, the chylothorax did not decrease with conservative therapy. Therefore, RAI was administered. Subsequently, the chylothorax and goiter improved more quickly than expected. This case illustrates that chylothorax associated with a substernal goiter in Graves' disease can be treated successfully with radioactive iodine instead of surgery.

    In some children, psychological events have appeared to be important in the triggering of Graves' disease. This report examines the case histories of three children in whom the appearance of symptomatology of Graves' disease was associated with depression following the death of a loved one. An analysis of neuroendocrine and immunologie pathways suggests that depression, set off by bereavement, causes low levels of norepinephrine in the brain. The latter in turn may mediate an increase in ACTH and cortisol, leading to reductions in immune surveillance and resultant production of thyroid-stimulating immunoglobulins, hence the development of Graves' disease.

    Herein we report a 36-year-old man with hyperparathyroidism and a past history of internal irradiation to the thyroid. Twelve years previously at age 24 years he had received 8 mCi of radioactive iodine for Graves' disease. An additional dose of 4 mCi was required 3 years later. A right lower parathyroid adenoma (28 x 23 x 20 mm, 5.7 g) was found at neck exploration. Although the association of external ionizing radiation to the head and neck and the subsequent development of hyperfunctioning parathyroid glands has been described in recent years, there are only 4 cases in the literature of parathyroid surgery for hyperparathyroidism secondary to earlier treatment with radioactive iodine for Graves' disease. In a long-term follow-up of 180 patients treated with radioactive iodine for Graves' disease, neither hypercalcemia nor hypophosphatemia was found. Whether internal radiation therapy can be a causative factor in the development of hyperparathyroidism should be elucidated in future. However, it seems reasonable to suggest that patients whose hyper-thyroidism has been treated with radioactive iodine should have their scrum calcium levels examined at 5-year intervals. (author)

    Although the etiology of Graves' disease is still not clear, it is generally suggested that environmental factors such as infections contribute to the development of Graves' disease. We report here three cases of Graves' disease which presented simultaneously with infectious mononucleosis due to primary EBV infection. Acute EBV infection might play an important role in the onset of Graves' disease. These three women complained of a sore throat or neck pain, resembling subacute thyroiditis. In the case of thyrotoxicosis accompanied by sore throat or neck pain, Graves' disease must be distinguished from subacute thyroiditis.

    In most cases, the histopathologic and cytologic distinction between Graves' disease and papillary thyroid carcinoma is relatively easy, but on occasion Graves' disease may simulate a thyroid papillary carcinoma. For example, papillary fronds with fibrovascular cores may be present in both Graves' disease and papillary carcinoma. p27kip1 (p27) is a cyclin-dependent kinase inhibitory protein that has been shown to be an independent prognostic factor in a variety of human tumors. Our previous studies of p27 expression in hyperplastic and neoplastic endocrine lesions showed that the level of p27 was quite different in these two conditions. To determine if this distinction could also be made between Graves' disease and papillary carcinoma, we analyzed expression of p27 and other cell cycle proteins in a series of cases of Graves' disease with papillary hyperplasia and a series of papillary thyroid carcinomas. Formalin-fixed paraffin-embedded tissues from 61 randomly selected patients with thyroid disease, including 29 cases of Graves' disease with papillary architectural features and 32 cases of papillary carcinoma, were analyzed for expression of p27, Ki-67, and DNA topoisomerase II alpha (topo II alpha) by immunostaining. The distribution of immunoreactivity was analyzed by quantifying the percentage of positive nuclei that was expressed as the labeling index (LI) plus or minus the standard error of the mean. The papillary hyperplasia of Graves' disease had a p27 LI of 68.2 +/- 3.1 (range, 24 to 88), whereas papillary carcinomas had a LI of 25.6 +/- 2.5 (range, 12 to 70) (P hyperplasia in Graves' disease and papillary carcinoma. These results indicate that p27 protein expression is significantly higher in papillary hyperplasia of Graves' disease compared to papillary carcinoma, which may be diagnostically useful in difficult cases.

    The etiology of Graves' orbitopathy (GO) remains enigmatic. Optimal therapeutic choices for the hyperthyroidism associated with Graves' disease (GD) in the presence of GO remain controversial. Whether antithyroid drugs (ATDs), radioiodine (RAI), or thyroidectomy should be favored in such patients...... - independent of extent - do not influence the natural course of GO. RAI can cause de novo development or progression of GO, which is largely preventable with oral steroid prophylaxis. In patients with mild GO, the thyroid treatment is largely independent of GO.

    The development of Grave's ophthalmopathy (GO) following radioiodine (RI) treatment for Grave's thyrotoxicosis, though controversial, is well described. The development of ophthalmopathy following RI treatment for toxic nodular goitre is much less recognised. We report a 49 year-old female patient who developed thyrotoxicosis and GO after receiving RI treatment for toxic nodular goitre and we also review the relevant literature.

    Graves' disease is an autoimmune thyroid disease of complex inheritance. Multiple genetic susceptibility loci are thought to be involved in Graves' disease and it is therefore likely that these can be identified by genome wide association studies. This study aimed to determine if a genome wide association study, using a pooling methodology, could detect genomic loci associated with Graves' disease. Nineteen of the top ranking single nucleotide polymorphisms including HLA-DQA1 and C6orf10, were clustered within the Major Histo-compatibility Complex region on chromosome 6p21, with rs1613056 reaching genome wide significance (p = 5 × 10 -8 ). Technical validation of top ranking non-Major Histo-compatablity complex single nucleotide polymorphisms with individual genotyping in the discovery cohort revealed four single nucleotide polymorphisms with p ≤ 10 -4 . Rs17676303 on chromosome 1q23.1, located upstream of FCRL3, showed evidence of association with Graves' disease across the discovery, replication and combined cohorts. A second single nucleotide polymorphism rs9644119 downstream of DPYSL2 showed some evidence of association supported by finding in the replication cohort that warrants further study. Pooled genome wide association study identified a genetic variant upstream of FCRL3 as a susceptibility locus for Graves' disease in addition to those identified in the Major Histo-compatibility Complex. A second locus downstream of DPYSL2 is potentially a novel genetic variant in Graves' disease that requires further confirmation.

    The Palaeolithic paintings of Baja California constitute an important contribution to the national, historic and cultural patrimony of Mexico. The aim of this investigation was to determine the physicochemical characteristics, the microstructure and texture of these polychrome paintings, painted on rocks encountered in the mountainous, desert/arid zones of Baja California and Baja California South. The first stage of this work was devoted to the examination and recording of the cave paintings of 'El Vallecito', a narrow fluvial valley displaying large granitic rocks emerging from the sandy soil. Tiny painting samples were collected and analyzed by SEM, EDS and FTIR techniques. The painters used four main colours: red, black, yellow and white. The paint raw materials are mineral pigments: white (kaolin, calcite, and gypsum), red (hematite), yellow (ochre, limonite), black (charcoal from burnt wood or calcined bones) and water as a diluent and/or a binder, all encountered in the painters habitat. The minerals were collected, ground and sometimes heated to change their tone. By mixing with water, a spreadable paste or a thick slurry was produced, which was applied with the fingers for lines or a piece of animal skin for figures, respectively. The 100% solids, dry paint converts into a dense, hard layer, incrusted into the grainy, rough, hollow granite rock surface. This paint might be called s tone on stone , explaining its permanence for centuries enduring heat, wind and weather. A simulation of the painting technique was done at the Materials and Corrosion Laboratory, UABC by collecting mineral pigments, preparing the paint as a paste or slurry and applying it on a granitic rock. Knowing the paint composition, production and application techniques will be useful in e conservation and restoration of cave paintings and stone-built, ancient structures such as pyramids, cathedrals and monuments.

    We herein report a child case of autoimmune hepatitis (AIH) accompanied with Graves' disease. Elevated aminotransferase levels were found in a 12-year-old Japanese girl with Graves' disease. In her first liver biopsy, necrosis and inflammation was limited to the centrilobular area, while the second biopsy showed different findings. Namely, portal injury newly appeared, including interface hepatitis, which represents the histological characteristics of AIH. As the histological findings at the onset of AIH do not always show typical findings, a re-biopsy is considered to be important in individuals suspected to have AIH. AIH should be included in the differential diagnosis of liver dysfunction in Graves' disease, even in children.

    There is an ongoing debate about whether robotic thyroidectomy (RT) is appropriate for Graves' disease. The aim of this study was to compare the safety of bilateral axillo-breast approach (BABA) RT with that of open thyroidectomy (OT) in patients with Graves' disease. From January 2008 to June 2014, 189 (44 BABA RT and 145 OT) patients underwent total thyroidectomy for Graves' disease. Recurrence of Graves' disease, intraoperative blood loss, hospital stay, and complication rates including recurrent laryngeal nerve (RLN) palsy and hypoparathyroidism were analyzed between BABA RT and OT groups, after propensity score matching according to age, gender, body mass index, surgical indication, the extent of operation, excised thyroid weight, and follow-up period. No patient experienced recurrence of Graves' disease after median follow-up of 35.0 months. Intraoperative blood loss (151.8 ± 165.4 mL vs. 134.5 ± 75.4 mL; p = 0.534) and hospital stay (3.4 ± 0.7 day vs. 3.3 ± 0.7 day; p = 0.564) were not different between BABA RT and OT groups. Complication rates including transient RLN palsy (11.4 vs. 11.4%; p = 1.000), transient hypoparathyroidism (18.2 vs. 20.5%; p = 0.787), permanent RLN palsy (0 vs. 2.3%; p = 0.315), and permanent hypoparathyroidism (2.3 vs. 2.3%; p = 1.000) were also comparable between groups. BABA RT for Graves' disease showed comparable surgical completeness and complications to conventional OT. BABA RT can be recommended as an alternative surgical option for patients with Graves' disease who are concerned about cosmesis.

    Objective: To evaluate the method and result of thyroid artery embolization as a new therapy for Graves disease. Methods: Ten patients with Graves disease underwent selective thyroid artery embolization. Totally 25 thyroid arteries were embolized with PVA microspheres. The indications to this therapy were as following: Graves disease with recurrent clinical symptoms or with leucopenia during the period of treating with administration of antithyroid drugs or recurrence after subtotal thyroidectomy. Results: Serum level of thyroid hormones dropped significantly [median FT 3 from 20.90 pmol/L (13.36-50.92 pmol/L) to 7.81 pmol/L (3.67-35.3 pmol/L), median FT 4 from 57.9 pmol/L (30.96-57.9 pmol/L) to 28.13 pmol/L (20.44-39.60 pmol/L), (P < 0.005)] and then followed-up for 5-8 months. The symptoms of hyperthyroidism were controlled in 7 patients and the remaining 3 cases were treated with lower dosage of antithyroid drug therapy. None serious complications were found. Conclusions: thyroid artery embolization represents a promising new method for treating Graves disease with safety and good clinical results. Further investigation would be required to assess its long-term effect

    Moyamoya disease is a cerebrovascular condition that results in the narrowing of the vessels of the circle of Willis and collateral vessel formation at the base of the brain. Although relationships between Graves' disease and cerebrovascular accidents in Moyamoya disease are obscure, the coexistence of the two diseases is noteworthy. Moyamoya disease has been rarely reported in adolescent patients with thyrotoxicosis. Recently, we encountered two adolescent Korean patients with Moyamoya disease associated with Graves' disease who presented with episodic right-sided hemiparesis and syncope. These two girls who had Graves' disease had no history of other diseases or head trauma. A thyroid function test revealed a euthyroid state and a high thyroid-stimulating hormone (TSH) receptor antibody titer at that time. The patients were diagnosed with Moyamoya disease based on brain magnetic resonance angiography and cerebral four-vessel angiography. The patients underwent cranial revascularization by encephalo-duroarterio-synangiosis as soon as a diagnosis was made, which resulted in successful symptom resolution. They fared well and had no additional neurological symptoms as of their last follow-up visits. Here, we report these two cases of confirmed Moyamoya disease complicated by Graves' disease with a review of the literature, and discuss the possible association between the two diseases. To our knowledge, this is the first report in South Korea on Moyamoya disease associated with Graves' disease in adolescents with a euthyroid.

El estudio tuvo un enfoque post positivista. Empleó la metodología mixta en su modalidad de secuencial exploratoria. En la fase cualitativa se recolectaron datos aplicando entrevistas semiestructuradas a seis estudiantes de primero y segundo de secundaria; los resultados fueron analizados mediante una codificación inductiva. En la fase cuantitativa se aplicó un autorreporte con escala Likert a 50 estudiantes de secundaria. Los datos de esta etapa se sometieron a análisis descriptivo, psicométrico y de relaciones. Se descubrió que el alumnado de secundaria competente en desarrollo de pensamiento crítico tiene habilidades de resolución de problemas, de emisión de juicios y de disposición hacia el pensamiento crítico. Se destaca su solidaridad, el gusto por compartir su conocimiento y por ayudar a quien se lo solicita. También se encontró que es mínima la diferencia de esta competencia entre hombres y mujeres, aunque en el contexto del aula se reflejen más las capacidades de las mujeres. Estos hallazgos pueden ser tomados en cuenta en la práctica educativa para impulsar el desarrollo del pensamiento crítico en estudiantes y, a la vez, su aprendizaje; puesto que al fortalecer la competencia del pensamiento crítico mediante la práctica, se ponen en juego diferentes habilidades, conocimientos y actitudes, lo cual es afín al enfoque de educación actual en México, al enfoque basado en competencias.

    To assess the value of echo-tracking technology in evaluating endothelial function of the femoral artery in patients with Grave's disease. Thirty-four patients with Grave's disease patients and 30 normal adults as controls were recruited in this study. The intima-media thickness (IMT), arterial stiffness (β), pressure strain elastic modulus (Ep), arterial compliance (AC), pulse wave conducting velocity (PWVβ) and augmentation index (AI) parameters were examined using echo-tracking technology for evaluating the right femoral arterial elasticity. Compared with the control subjects, the patients with Grave's disease showed significantly increased β, Ep, and PWVβ and significantly decreased AC (P0.05). In patients with Grave's disease, β and Ep were positively correlated with FT3, FT4, TT3, TT4, and PWVβ was positively correlated with FT3 and FT4. Echo-tracking technology can provide more accurate quantitative evidences for early diagnosis of femoral artery endothelial dysfunction in patients with Grave's disease, but the influence of procedural factors on the measurement accuracy should be considered in the evaluation.

    Thyrotropin-producing pituitary tumor is relatively rare. In particular, concurrent cases associated with Graves' disease are extremely rare and only nine cases have been reported so far. We describe a case of a thyrotropin-producing pituitary adenoma concomitant with Graves' disease, which was successfully treated. A 40-year-old Japanese woman presented with mild signs of hyperthyroidism. She had positive anti-thyroid-stimulating hormone receptor antibody, anti-thyroglobulin antibody, and anti-thyroid peroxidase antibody. Her levels of serum thyroid-stimulating hormone, which ranged from low to normal in the presence of high levels of serum free thyroid hormones, were considered to be close to a state of syndrome of inappropriate secretion of thyroid-stimulating hormone. Magnetic resonance imaging showed a macropituitary tumor. The coexistence of thyrotropin-producing pituitary adenoma and Graves' disease was suspected. Initial therapy included anti-thyroid medication, which was immediately discontinued due to worsening symptoms. Subsequently, surgical therapy for the pituitary tumor was conducted, and her levels of free thyroid hormones, including the thyroid-stimulating hormone, became normal. On postoperative examination, her anti-thyroid-stimulating hormone receptor antibody levels decreased, and the anti-thyroglobulin antibody became negative. The coexistence of thyrotropin-producing pituitary adenoma and Graves' disease is rarely reported. The diagnosis of this condition is complicated, and the appropriate treatment strategy has not been clearly established. This case suggests that physicians should consider the coexistence of thyrotropin-producing pituitary adenoma with Graves' disease in cases in which thyroid-stimulating hormone values range from low to normal in the presence of thyrotoxicosis, and the surgical treatment of thyrotropin-producing pituitary adenoma could be the first-line therapy in patients with both thyrotropin-producing pituitary adenoma

    Objective: To investigate the clinical diagnostic value of serum TRAb levels determination in patients with Graves' disease. Methods: Serum TRAb (with RRA), FT 3 , FT 4 , TSH (with CLIA) levels were measured in 223 patients with Graves' disease both before and 6, 12, 36 months after treatment with antithyroid drugs (ATD) as well as in 50 controls. Results: Positive rate of serum TRAb was 93.3% in patients with Graves' disease before treatment. Six months after ATD therapy the positive rate dropped to 41.3%, being still significantly higher than that in controls (P<0.05). The TRAb positive rate dropped steadily with 12 (18.3% ), 24 (8.9% ) and 36 months (4.9%) of ATD treatment. In the 21 patients who had hyperthyroidism recurred after the course of treatment, TRAb remained positive in 18 of them (80.7%). Conclusion: Persistent positive TRAb despite euthyroid status in patients with Graves' disease after seemingly successful ATD treatment donates persistent immunodysfunction and possible recurrence. It is mandatory to continue ATD treatment until TRAb negative. (authors)

    The purpose of the present study was to investigate CT Hounsfield unit (H.U.) of the thyroid in hyperthyroid and euthyroid Graves' disease and destructive thyrotoxicosis. The mean thyroid CT number in 95 controls was 122±18 H.U.(±SD) and did not change significatly with advancing age. The mean thyroid CT number (±SD) of 85±22 H.U. in 60 patients with hyperthyroid Graves' disease was significantly lower than either in normal controls or 116±22 H.U. in 11 patients with euthyroid Graves' disease. Comparison of thyroid hormones and TSH receptor Ab values of untreated patients with a normal and an abnormally low thyroid CT number showed that serum total and free T 3 were significantly higher in the latter group than the former group. With respect to the effect of methimazol (MMI) on the thyroid CT number, in the untreated 10 patients with a low thyroid CT number, the initial mean CT number was 65±11 H.U. and increased significantly to 76±14 H.U. after treatment with MMI. In contrast, in 6 patients with a normal thyroid CT number prior to therapy, the initial mean thyroid CT number was 102±11 H.U. and fell significantly to 84±16 H.U. after treatment with MMI. The thyroid CT number in destructive thyrotoxicosis is markedly decreased to less than 70 H.U. and the mean values of 57±7 H.U. in 6 patients with silent thyroiditis and of 61±5 H.U. in 7 with subacute thyroiditis differ significantly from Graves' disease. In conclusion, the thyroid CT number is significantly reduced in hyperthyroid Graves' disease, normal in euthyroid Graves' disease and markedly decreased in destructive thyrotoxicosis. The high T-3 value seemed to play an important role in the pathogenesis of a decline in the thyroid CT number in Graves' disease. An antithyroid drug therapy caused two different changes in the thyroid CT number, depending on whether the thyroid CT number prior to therapy was normal or low. (author)

    Polycystic ovary syndrome (PCOS) and Graves' disease are the common causes of menstrual irregularity leading to infertility in women of child-bearing age. A 21-year-old female patient visited us with complaints of oligomenorrhea and hand tremor. She was diagnosed as having PCOS and hyperthyroid Graves' disease, simultaneously. She had low body weight (BMI: 16.4 kg/m(2)), mild hirsutism, and thyrotoxicosis. The patient was treated with anti-thyroid drug and beta-blocker for about two years, and then recovered to normal thyroid function. Although some studies have suggested a connection between PCOS and autoimmune thyroiditis, no study indicated that PCOS is associated with Graves' disease until now. Here, we describe the first case report of a lean woman with normal insulin sensitivity presenting PCOS and Graves' disease simultaneously.

    The subjects of Raman and X-ray analyses were the beads from two necklaces found in ancient graves from the 11'"t"h and 12"t"h centuries at the Castle of Devin. One of the necklaces, consisting of 23 beads, was found in tomb 12/1980. Inside the grave, an incomplete skeleton of a woman was found, oriented in the west - east direction. The skull, shoulder blades and lower limbs were preserved in good condition. The grave contained a rich inventory: a silver ear-ring at the left side of the skull, a necklace between the shoulder blades and a ring on the right side at the height of the right hand. The other necklace, consisting of six stones, was found in grave 145/1985 in which, similarly like in the first grave, a woman's skeleton was discovered. The stones were found below the mandible. All beads are drilled through axially. (authors)

    Pruritus is a lesser known symptom of hyperthyroidism, particularly in autoimmune thyroid disorders. This is a case report of a 27-year-old woman who presented with generalised pruritus at a primary care clinic. Incidental findings of tachycardia and a goiter led to the investigations of her thyroid status. The thyroid function test revealed elevated serum free T4 and suppressed thyroid stimulating hormone levels. The anti-thyroid antibodies were positive. She was diagnosed with Graves' disease and treated with carbimazole until her symptoms subsided. Graves' disease should be considered as an underlying cause for patients presenting with pruritus. A thorough history and complete physical examination are crucial in making an accurate diagnosis. Underlying causes must be determined before treating the symptoms.

    The purpose of the present study was to investigate CT Hounsfield unit (H.U.) of the thyroid in hyperthyroid and euthyroid Graves' disease and destructive thyrotoxicosis. The mean thyroid CT number in 95 controls was 122[+-]18 H.U.([+-]SD) and did not change significatly with advancing age. The mean thyroid CT number ([+-]SD) of 85[+-]22 H.U. in 60 patients with hyperthyroid Graves' disease was significantly lower than either in normal controls or 116[+-]22 H.U. in 11 patients with euthyroid Graves' disease. Comparison of thyroid hormones and TSH receptor Ab values of untreated patients with a normal and an abnormally low thyroid CT number showed that serum total and free T[sub 3] were significantly higher in the latter group than the former group. With respect to the effect of methimazol (MMI) on the thyroid CT number, in the untreated 10 patients with a low thyroid CT number, the initial mean CT number was 65[+-]11 H.U. and increased significantly to 76[+-]14 H.U. after treatment with MMI. In contrast, in 6 patients with a normal thyroid CT number prior to therapy, the initial mean thyroid CT number was 102[+-]11 H.U. and fell significantly to 84[+-]16 H.U. after treatment with MMI. The thyroid CT number in destructive thyrotoxicosis is markedly decreased to less than 70 H.U. and the mean values of 57[+-]7 H.U. in 6 patients with silent thyroiditis and of 61[+-]5 H.U. in 7 with subacute thyroiditis differ significantly from Graves' disease. In conclusion, the thyroid CT number is significantly reduced in hyperthyroid Graves' disease, normal in euthyroid Graves' disease and markedly decreased in destructive thyrotoxicosis. The high T-3 value seemed to play an important role in the pathogenesis of a decline in the thyroid CT number in Graves' disease. An antithyroid drug therapy caused two different changes in the thyroid CT number, depending on whether the thyroid CT number prior to therapy was normal or low. (author).

    2011-06-01

    Unilateral Graves' disease is a rare disease variant that can occur in a bilobar thyroid gland. We report the first documented case of unilateral Graves' disease in the left lobe of a bilobar thyroid gland and review the pertinent literature. A 48-year-old man presented in June 2010 with thyrotoxicosis. I-131 radioisotope uptake was elevated at 33.4%, and scintigraphy revealed that uptake of the radioisotope was uniformly increased in the left lobe of the thyroid gland. Ultrasonography of the thyroid gland revealed a non-nodular, enlarged, and heterogeneous left lobe; Doppler investigation of the lobe showed hypervascularity classically seen in Graves' disease. The right lobe of the thyroid, on the other hand, appeared homogeneous and hypovascular on ultrasonography. Thyroid-stimulating immunoglobulin was significantly elevated at 191% (reference range disease was the most likely diagnosis. As has occasionally been described in the literature, unilateral involvement of the thyroid gland is a rare presentation of Graves' disease. Pre-existing functional or structural differences (either congenital or acquired) between the two lobes may contribute to this rare presentation. To our knowledge, this is the first reported case of unilateral Graves' disease presenting in the left lobe of a bilobar thyroid gland. Although the pathophysiology of unilateral Graves's disease has not been clearly elucidated, clinicians should be aware that Graves' disease can present unilaterally in either lobe of the thyroid gland.

    Microclimate measurements in a Neolithic passage grave in Denmark have shown that natural ventilation through the open entrance destabilizes the relative humidity (RH), whereas a sealed entrance gives a much more stable RH, above 90%. Episodes of condensation occur on the stone surfaces in summer...... with too much ventilation and in winter with too little ventilation. Soil moisture measurements above, below, and beside the grave mound indicate that rainfall on the mound is not a significant source of moisture to the chamber, whereas the ground below the sealed chamber is constantly moist. The chamber...... can be kept dry all year by putting a moisture barrier membrane over the floor. Apart from the more variable climate within the open chamber, there is also a significant penetration of ozone, which is absent in the sealed chamber. The ozone may have deteriorated the folds of birch bark put between...

    Full Text Available Abstract Introduction Pseudotumor cerebri is an entity characterized by elevated intracranial pressure with normal cerebrospinal fluid and no structural abnormalities detected on brain MRI scans. Common secondary causes include endocrine pathologies. Hyperthyroidism is very rarely associated and only three case reports have been published so far. Case presentation We report the case of a 31-year-old Luso-African woman with clinical symptoms and laboratory confirmation of Graves' disease that presented as pseudotumor cerebri. Conclusion This is a rare form of presentation of Graves' disease and a rare cause of pseudotumor cerebri. It should be remembered that hyperthyroidism is a potential cause of pseudotumor cerebri.

    Severe aplastic anaemia (SAA) is considered to be an autoimmune disorder affecting the haematopoietic cells and most often is idiopathic. An association between SAA and other autoimmune diseases is rare and has been described in adults for eosinophilic fasciitis, thymomas, systemic lupus erythematosus and thyroid disorders. We describe the first paediatric patient with chronic relapsing SAA and Grave's disease. We discuss the difficulty in diagnosis of Grave's disease, the possibility of its manifestation due to withdrawal of immunosuppressants, and issues to consider in the treatment of this disease in the setting of bone marrow failure.

    Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to deficiency of sex steroid hormone. Graves' disease is also an important cause of secondary osteoporosis. However, IHH does not preclude the development of primary hyperthyroidism caused by Graves' disease, leading to more severe osteoporosis rapidly. Here, we describe the first case of 35-year-old Asian female patient with IHH accompanied by Graves' disease and osteoporosis-induced multiple fractures. Endocrine laboratory findings revealed preserved anterior pituitary functions except for secretion of gonadotropins and showed primary hyperthyroidism with positive autoantibodies. Sella magnetic resonance imaging showed slightly small sized pituitary gland without mass lesion. Dual energy X-ray absorptiometry revealed severe osteoporosis in lumbar spine and femur neck of the patient. Plain film radiography of the pelvis and shoulder revealed a displaced and nondisplaced fracture, respectively. After surgical fixation with screws for the femoral fracture, the patient was treated with antithyroid medication, calcium, and vitamin D until now and has been recovering fairly well. We report a patient of IHH with Graves' disease and multiple fractures that is a first case in Korea.

On the basis of qualitative and quantitative analyses of B- and T-cell subsets, and autoantibody levels obtained in other...... diseases before and after rituximab therapy, the authors interpret the results of the only two clinical investigations of the efficacy of rituximab in the treatment of Graves' disease and Graves' opthalmopathy reported so far. No significant effect on autoantibody levels was observed. Nonetheless, 4 out...... of 10 Graves' disease patients remained in remission 400 days after rituximab treatment versus none in the control group, and remarkable improvements in the eye symptoms of patients with Graves' ophthalmopathy were observed.

    Full Text Available Mexico needs to exploit its renewable resources and many studies have determined the great renewable potential it has using wind energy. However it is necessary to calculate the amount of this resource for small urban communities, which in this country lack essential services such as electricity. This study is focused in the Baja California Peninsula, using GIS as a tool to identify small urban zones with higher wind power. For this work data was analyzed from meteorological stations and recorded every 10 min for two years (2012–2014. Weibull distribution, linear regression, kriging interpolation, power and energy output and useful hours were calculated for each station. It was found that the total energy generated is 38,603,666 kWh per year and the mean of useful hours is 5220 h per year for the whole Peninsula. Maps of Wind Power Density (WPD show a good power per square meter, GIS shows the areas with the most wind power where it can be used i.e., the state of Baja California wind power can generate electricity for 12% of those communities, meanwhile for Baja California Sur, the electric power generation could electrify almost 25% of the total of small urban communities.

    The majority of pediatric patients with Graves' disease will ultimately require definitive therapy in the form of radioactive iodine (RAI) ablation or thyroidectomy. There are few studies that directly compare the efficacy and complication rates between RAI and thyroidectomy. We compared the relapse rate as well as the acute and long-term complications of RAI and total thyroidectomy among children and adolescents with Graves' disease treated at our center. Medical records from 81 children and adolescents with a diagnosis of Graves' disease who received definitive therapy over a 12-year period were reviewed. Fifty one patients received RAI and 30 patients underwent thyroidectomy. The relapse rate was not significantly different between RAI and thyroidectomy (12.1% vs. 0.0%, p=0.28). There were no acute or long-term complications in the RAI group, but there were eight cases of hypoparathyroidism (two transient and six permanent) in the thyroidectomy group. None of the patients developed a recurrent laryngeal nerve injury. RAI is a safe and effective option for treatment of children and adolescents with Graves' disease. In light of the rate of permanent hypoparathyroidism seen at our center with thyroidectomy and previously published long-term safety of RAI, we recommend RAI as the first line treatment for children and adolescents with Graves' disease. For those centers performing thyroidectomies, we recommend that each center select 1-2 high-volume pediatric surgeons to perform all thyroid procedures, allowing individuals to increases case volume and potentially decrease long-term complications of thyroidectomy.

    Graves` ophthalmopathy can occur in 25-30% of patients with hyperthyroidism. This condition can result in serious visual disturbance and disfigurement. The treatment options for symptomatic disease are oral corticosteroids or orbital irradiation. Ten patients with Graves` ophthalmopathy were treated with external beam radiotherapy at Saint Lukes Hospital from March 1991 to February 1994. Eight of these patients had excellent response with minimal morbidity. A dose of 2000 cGy in 10 fractions over 2 weeks is considered to be sufficient to alleviate symptoms in most patients. It is concluded that orbital radiotherapy is effective and well tolerated, and should replace corticosteroid therapy as the initial treatment modality in these patients. A minimum follo-up of 6 months is considered adequate for detecting radiation-induced complications. 7 refs., 1 fig.

    Grave's ophthalmopathy is an inflammatory, autoimmune disorder often associated with Grave's disease. The inflammatory infiltration involves the retrobulbar fatty tissue and the extrinsic eye muscles, causing proptosis, extraocular muscle dysfunction and often diplopia. Orbital decompression is an effective treatment in such cases, particularly when resistant to drugs and external radiation therapy. This work compares the results of orbital decompression performed by removing: a) the medial and lateral walls (Mourits technique) in 10 patients (19 orbits) and b) the medial and lower walls (Walsh-Ogura technique) in 17 patients (31 orbits). The results show that removing the floor of the orbit enables better reduction of proptosis but more easily leads to post-operative diplopia. Thus it proves necessary to combine the two techniques, modifying the surgical approach on a case-by-case basis.

    The state of Baja California Sur (Mexico) does not form part of the national interconnected electrical system of the country, reason why is local its electrical power supply; one of the alternatives to cover future demands is the use of gas-based combined cycles, which presents the additional problem of including a high price for gas transportation in its costs. In order to reduce total costs, including investment, fuels and operation and maintenance in the operation of the Baja California Sur state electricity system in the coming years, mainly due to the estimated natural gas cost order of $11.50 dollars per million BTU, a proposal is presented to reduce the costs of the electrical system by replacing the necessary combined cycles with the new Small Modular Reactor type nuclear reactors, this alternative is economically competitive.

    Thyrotropin-secreting adenoma (TSHoma) is rare. Even though the thyrotoxicosis is mild in patients with TSHoma, it is still a rare cause of arrhythmia, ignore of mild disfunction of thyroid function of TSHoma can lead to the delayed diagnosis of pituitary tumor or leading to recurring of complications. Graves' disease is an auto-immue endocrinological disorder. Association of TSHoma and Graves's disease is extremely rare. Coexistence of these two diseases made the diagnosis and treatment complicated. This patient was a 55-year-old man who had been referred to the department of endocrinology and metabolism of the West China Hospital due to recurrent atrial fibrillation (AF) and thyroxicosis. Examinations revealed pituitary thyrotropin-secreting macroadenoma with Graves' disease. We conducted transsphenoidal surgery. Thyrozol was used to treat the recurrence of Graves' disease after pituitary surgery. The TSHoma was successfully cured, and recurrent Graves' disease was controlled very well. The association of TSHoma and Graves' disease is extremely rare. Even though the clinical features of thyrotoxicosis are milder in patients with TSHoma, thyroid function tests are still important clinical assessment of patients with AF, which is an arrhythmia associated with hyperthyroidism. TSHoma is a rare cause of thyrotoxicosis; however, ignoring of the mild disfunction caused by TSHoma can lead to the delayed diagnosis of pituitary tumors or to recurring of complications of TSHoma.

    The aim of this study was to evaluate the usefulness of diffusion-weighted magnetic resonance imaging (DWMRI) for differentation between Graves' disease and Hashimoto's thyroiditis. Fifty patients (27 Graves diseases and 23 Hashimoto thyroiditis) and twenty healthy volunteers were examined using T1, T2 and DWMRI. The patients were diagnosed on the basis of physical findings and the results of thyroid function tests and serological tests. Circular ROIs were positioned on the bilateral thyroid lobes and isthmus. All measurements were repeated three different b values including 100, 600 and 1000 s/mm2 in all cases. ADC (Apparent diffusion coefficient) maps were calculated automatically with the MR system. Mean ADC values were 2.93 × 10-3, 1.97 × 10-3 and 1.62 × 10-3 mm2/s in the healthy volunteers; 3.47 × 10-3, 2.25 × 10-3 and 1.64 × 10-3 mm2/s in Graves' disease; 2.53 × 10-3, 1.76 × 10-3, 1.28 × 10-3 mm2/s in Hashimoto thyroiditis for b100, b600 and b1000, respectively. The ADC values of the Graves diseases were higher than healty volunteers and Hashimoto thyroiditis. ADC values were statistically significant for differentation between Hashimoto thyroiditis and Graves' disease all b values (p Hashimoto thyroiditis and Graves' disease.

    Radioiodine[131I] has been used for the treatment of Graves' hyperthyroidism since the late 1940's and is now generally regarded as the treatment of choice for Graves' hyperthyroidism who does not remit following a course of antithyroid drugs. But for the dose given, several different protocols have been described by different centers, each attempting to reduce the incidence of long-term hypothyroidism while maintaining an acceptable rate control of Graves' hyperthyroidism. Our goals were to evaluate effective half-life and predict absorbed dose in Graves' hyperthyroidism patients, therefore, to calculate and read minister radioiodine activity needed to achieve aimed radiation dose. Our data showed that the mean effective 131I half-life for Graves' disease is 5.3 days(S.D=0.88) and mean biologic half-life is 21 days, range 9.5-67.2 days. The mean administered activity and the mean values of absorbed doses wet: 532 MBq(S.D.=254), 112 Gy (S.D.=50.9), respectively. The mean activity needed to achieve aimed radiation dose were 51 MBq and marked differences of 131I thyroidal uptake between tracer and therapy occurred in our study. We are sure that the dose calculation method that uses 5 days thyroidal 131I uptake measurements after tracer and therapy dose, provides sufficient data about the effective treatment in Graves' hyperthyroidism.

    Contradictory results have been obtained with regards to the effect of various treatment modes on the exacerbation of Graves' ophthalmopathy, probably because the number of patients in each study was small and some studies were analyzed only in relation to one type of treatment. To circument these problems, we studied the course of Graves' ophthalmopathy after various modes of therapy for thyrotoxicosis among 537 patients with Graves' disease. A total of 537 patients with Graves' disease were prospectively studied over an 11-year period. Thirty-one patients were lost to follow-up during the first six months after treatment and were excluded from the study. Of those remaining, 426 received one form of treatment, 79 received two kinds of therapy, and one received three kinds of therapy. Thus, surgical treatments numbered 164, radioactive iodine-131 ( 13 1I) treatments numbered 241, and medical treatments numbered 182. Ocular signs were considered improved or exacerbated by the following criteria: decrement or increment of the exophthalmos of 2 mm or more, improvement or deterioration of visual acuity, and regression or progression of extraocular muscle involvement causing diplopia. Among patients who did not have infiltrative ophthalmopathy before treatment, there was no difference in the occurrence of posttreatment exophthalmos in the surgically, medically, and 131I-treated patients (7.1%, 6.7%, and 4.9%, respectively). The incidence and the degree of progression of ophthalmopathy in patients who already had exophthalmos before treatment were similar in the medically, surgically, and 131I-treated groups (19.2%, 19.8%, and 22.7%, respectively). Most of the progression occurred in the posttreatment euthyroid stage. The incidence of improvement of ophthalmopathy was also similar 14.1%, 12.6%, and 12.3% in the medically, surgically, and 131I-treated patients

  9. Remote sensing studies and morphotectonic investigations in an arid rift setting, Baja California, Mexico

    El-Sobky, Hesham Farouk

    The Gulf of California and its surrounding land areas provide a classic example of recently rifted continental lithosphere. The recent tectonic history of eastern Baja California has been dominated by oblique rifting that began at ˜12 Ma. Thus, extensional tectonics, bedrock lithology, long-term climatic changes, and evolving surface processes have controlled the tectono-geomorphological evolution of the eastern part of the peninsula since that time. In this study, digital elevation data from the Shuttle Radar Topography Mission (SRTM) from Baja California were corrected and enhanced by replacing artifacts with real values that were derived using a series of geostatistical techniques. The next step was to generate accurate thematic geologic maps with high resolution (15-m) for the entire eastern coast of Baja California. The main approach that we used to clearly represent all the lithological units in the investigated area was objectoriented classification based on fuzzy logic theory. The area of study was divided into twenty-two blocks; each was classified independently on the basis of its own defined membership function. Overall accuracies were 89.6%, indicating that this approach was highly recommended over the most conventional classification techniques. The third step of this study was to assess the factors that affected the geomorphologic development along the eastern side of Baja California, where thirty-four drainage basins were extracted from a 15-m-resolution absolute digital elevation model (DEM). Thirty morphometric parameters were extracted; these parameters were then reduced using principal component analysis (PCA). Cluster analysis classification defined four major groups of basins. We extracted stream length-gradient indices, which highlight the differential rock uplift that has occurred along fault escarpments bounding the basins. Also, steepness and concavity indices were extracted for bedrock channels within the thirty-four drainage basins. The

    The use of radioiodine as the first line of treatment in Graves' disease is restricted in India because of its limited availability and an unrealistic risk perception associated with it. Additionally, the effectiveness of radioiodine ablation in Graves' disease is influenced by many factors. Prior medical antithyroid therapy is one such important factor. To analyze the efficacy of low dose radioiodine therapy (5 mCi) in treatment of naive patients of Graves' disease in comparison to that in which it was already primed with an antithyroid drug, carbimazole. A non-randomized, interventional study conducted in the Department of Medicine and Endocrinology of a tertiary care institute in South India. The study had two groups; Group A (36 treatment naive, uncomplicated Graves' disease patients) and B (34 Graves' disease patients on carbimazole prior to radioiodine therapy). Both groups had baseline clinical, biochemical evaluation and were reassessed at 3 and 6 months for evaluating the clinical status for possible documentation of cure. The cure rate was 61.1% in drug naive group and 58.8% in pretreated group at 6 months following radioiodine (P = 0.845). Higher baseline 999m technicium (99m Tc) uptake, male gender, BMI and higher baseline free thyroxine (fT4) level predicted treatment failure following radioiodine therapy. Administration of carbimazole prior to low dose radioiodine therapy does not alter the efficacy of radioiodine. Low fixed dose (5 mCi) of radioactive iodine may be a safe and effective primary therapeutic option in Graves' disease patients pretreated with antithyroid drugs.

    Geophysical techniques such as ground-penetrating radar (GPR) have been successfully used for forensic searches to locate clandestine graves and physical evidence. However, additional controlled research is needed to fully understand the applicability of this technology when searching for clandestine graves in various environments, soil types, and for longer periods of time post-burial. The purpose of this study was to determine the applicability of GPR for detecting controlled graves in a Spodosol representing multiple burial scenarios for Years 2 and 3 of a three-year monitoring period. Objectives included determining how different burial scenarios are factors in producing a distinctive anomalous response; determining how different GPR imagery options (2D reflection profiles and horizontal time slices) can provide increased visibility of the burials; and comparing GPR imagery between 500 MHz and 250 MHz dominant frequency antennae. The research site contained a grid with eight graves representing common forensic burial scenarios in a Spodosol, a common soil type of Florida, with six graves containing a pig carcass (Sus scrofa). Burial scenarios with grave items (a deep grave with a layer of rocks over the carcass and a carcass wrapped in a tarpaulin) produced a more distinctive response with clearer target reflections over the duration of the monitoring period compared to naked carcasses. Months with increased precipitation were also found to produce clearer target reflections than drier months, particularly during Year 3 when many grave scenarios that were not previously visible became visible after increased seasonal rainfall. Overall, the 250 MHz dominant frequency antenna imagery was more favorable than the 500 MHz. While detection of a simulated grave may be difficult to detect over time, long term detection of a grave in a Spodosol may be possible if the disturbed spodic horizon is detected. Furthermore, while grave visibility increased with the 2D

    To determine genetic diversity by comparing the whole genome sequences of cattle and human Mycobacterium bovis isolates from Baja California. A whole genome sequencing strategy was used to obtain the molecular fingerprints of 172 isolates of M. bovis obtained from Baja California, Mexico; 155 isolates were from cattle and 17 isolates were from humans. Spoligotypes were characterized in silico and single nucleotide polymorphism (SNP) differences between the isolates were evaluated. A total of 12 M. bovis spoligotype patterns were identified in cattle and humans. Two predominant spoligotypes patterns were seen in both cattle and humans: SB0145 and SB1040. The SB0145 spoligotype represented 59% of cattle isolates (n=91) and 65% of human isolates (n=11), while the SB1040 spoligotype represented 30% of cattle isolates (n=47) and 30% of human isolates (n=5). When evaluating SNP differences, the human isolates were intimately intertwined with the cattle isolates. All isolates from humans had spoligotype patterns that matched those observed in the cattle isolates, and all human isolates shared common ancestors with cattle in Baja California based on SNP analysis. This suggests that most human tuberculosis caused by M. bovis in Baja California is derived from M. bovis circulating in Baja California cattle. These results reinforce the importance of bovine tuberculosis surveillance and control in this region. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Management options are limited for the treatment of Graves' disease, and there is controversy regarding optimal treatment. We describe the demographic and biochemical characteristics of children with Graves' disease and the outcomes of its management. This is a retrospective study reviewing medical records from 2001 to 2011 at a tertiary-care paediatric hospital. Diagnostic criteria included elevated free T4 and total T3, suppressed TSH, and either positive thyroid-stimulating immunoglobulin or thyroid receptor antibodies or clinical signs suggestive of Graves' disease, for example exophthalmos. Patients were treated with antithyroid drugs (ATD), radioactive iodine, or thyroidectomy. The main outcome measures were remission after medical therapy for at least 6 months and subsequent relapse. A total of 291 children met diagnostic criteria. A total of 62 were male (21%); 117 (40%) were Hispanic, 90 (31%) Caucasian, and 59 (20%) African American. Mean age (±standard deviation) at diagnosis was 12·3 ± 3·8 (range 3-18·5) years. At diagnosis, 268 patients were started on an antithyroid drug and 23 underwent thyroid ablation or thyroidectomy. Fifty-seven (21%) children achieved remission and 16 (28%) of these patients relapsed, almost all within 16 months. Gender and ethnicity did not affect rates of remission or relapse. Of 251 patients treated with methimazole, 53 (21%) had an adverse reaction, including rash, arthralgias, elevated transaminases, or neutropenia. Most children with Graves' disease treated with ATD do not experience remission, but most remissions do not end in relapse. Adverse reactions to methimazole are common but generally mild. © 2016 John Wiley & Sons Ltd.

    Aplastic anemia (AA) is mediated by T-cell autoimmunity in the majority of cases; it is rare and mostly idiopathic in children. We describe a child, who developed AA following Graves' disease which could not be attributed to antithyroid drugs. We hypothesized that both diseases were caused by similar autoimmune process. We monitored the blood counts and did not administer any conventional treatment for AA assuming that the existing anti- hematopoietic stem cell humoral and cellular immunity might subside with induction of remission of Grave's disease. The child went into complete remission with the treatment of the Graves' disease.

    The effects of 131 I therapy on thyrotrophin binding inhibiting immunoglobulins (TBII) were studied in fifty-five patients with Graves' disease and five patients with toxic multinodular goitre (MNG). A group of forty patients with Graves' disease and four patients with toxic MNG were treated with drugs and acted as controls. In 78% of patients treated with 131 I there was a dramatic increase in serum TBII activity during the 3 months following therapy, whereas drug-treated patients showed a decrease (77%) or no change in TBII activity over the same period. TBII activity was not detectable in patients with toxic MNG before or after drug or 131 I therapy. Consideration of the mechanisms involved in the changes in serum TBII activity after 131 I treatment or during drug treatment provide insight into the basic defects responsible for the development of Graves' disease and suggest that both the thyroid and immune system are involved.

    A case of a 25-year-old woman with bulimia nervosa and Graves' disease is presented. Graves' disease is the cause of 50-80 % of hyperthyroidism. The disease is characterized by increases of thyroid hormone production, activation of the metabolism, and successive weight loss. Bulimia nervosa is characterized by purging behavior after binge eating episodes. We report a patient suffering from both entities. A pronounced non-compliance to the intake of antithyroid drugs (Carbimazole) correlated with eating disorder symptoms like negative evaluation of the body and fear of weight gain. Thus, elevated hyperthyroidism due to Graves' disease served as a purging method. During 8 weeks of inpatient psychotherapy, the patient adapted to a structured eating behavior. Self-esteem was less influenced by body shape and body weight, and compliance to endocrinological recommendations improved. Non-compliance to antithyroid drugs may be a symptom of an eating disorder. A careful and primarily non-confronting interdisciplinary diagnostic and treatment approach is required.

    Important growth of population in Baja California Peninsula has triggered the need for energy and fresh water. The most sustainable possibility for increasing the availability of fresh water is the use of renewable energy sources in desalination plants. The abundance of geothermal manifestations in the peninsula provides a reliable energy source for desalination purposes. Geothermal development of the Baja California Peninsula dates from the 70's, when the Cerro Prieto geothermal field started producing electricity. Two important cities, Tijuana and Ensenada, are located in the north-western area of Baja California. The city of Ensenada has a desalination plant that is due to be replaced and the geothermal resources of the area could be an option for the new desalination plant. Punta Banda, a region near Ensenada, was specially investigated to determine its geothermal potential. Subaerial springs and the submarine vents were sampled and studied in this work, also geological and geochemical studies were performed, moreover geoelectrical surveys were accomplished to characterize the hydrothermal system at depth. Even though saline intrusion is a severe problem in Ensenada (TDS higher than 3000), thermal springs away from the coast and coastal springs have salinities lower than sea water. According to the geoelectrical models obtained from profiles, the inferred conductive features can be related to thermal anomalies. The existence of hot springs located along a trend suggests that the dynamic of the thermal fluid is restricted by secondary faults.

    To determine clinical and biochemical features of Grave's disease at presentation predict response to medical and radioiodine treatment. We carried out a retrospective 10-year study of 194 consecutive Saudi subjects with Grave's disease who was treated with antithyroid drugs, radioiodine therapy, or both, between January 1995 and December 2004 at King Khalid University Hospital, Riyadh, Saudi Arabia. At diagnosis, the mean age was 32+-0.9 years. Only 26% of patients had successful outcome after a course of antithyroid medication. None of the clinical or biochemical factors were associated with a favorable outcome of antithyroid treatment. One dose of radioiodine [13-15 mCi (481-555 MBq)] cured hyperthyroidism in 83% of patients. Presence of ophthamopathy at presentation was shown to be a significant contributing factor to failure to respond to a single dose of radioiodine (odds ratio, 6.4; 95%CI, 1.51-24.4; p<0.01). Failure of radioiodine treatment was also associated with higher serum free T3 concentration at presentation (p=0.003). In patients with Grave's hyperthyroidism, radioiodine treatment is associated with higher success rate than antithyroid drugs. A dose of 13-15 mCi (481-555 MBq) seems to practical and effective, and should be considered as first line therapy. Patients with high free T3 concentration and, those with ophthalmopathy at presentation were more likely to fail radioiodine treatment. A higher dose of radioiodine may be advisable in such patients.

    To evaluate the prevalence of mood and anxiety disorders in women with treated hyperthyroidism caused by Graves' disease and to compare them with the prevalence of such findings in women without past or present thyroid disease. Thirty inpatient women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease and 45 women hospitalized for treatment of gynecologic disorders such as abnormal vaginal bleeding, benign tumors or infertility were evaluated for the prevalence of mood and anxiety diagnoses using a standard Mini-International Neuropsychiatric Interview and for mood and anxiety ratings using the Profile of Mood States (POMS). At the time of assessment, it was discovered that 14 of 30 women with treated hyperthyroidism caused by Graves' disease were still hyperthyroid, while 16 women were euthyroid. Significantly greater prevalence of social anxiety disorder, generalized anxiety disorder, major depression and total mood and anxiety disorders, as well as higher symptom scores on the POMS, was found in hyperthyroid women with Graves' disease in comparison with the control group. A prevalence of total anxiety disorder, as well as history of mania or hypomania and lifetime bipolar disorder, but not lifetime unipolar depression, was more frequent in both the euthyroid and the hyperthyroid subgroups of study women in comparison with the control group. These results confirm a high prevalence of mood and anxiety disorders in women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease. Hyperthyroidism plays a major role in psychiatric morbidity in Graves' disease.

    A young female presented with evidence of right-sided heart failure and was subsequently found to have significant pulmonary artery hypertension (PAH). Because of her normal left ventricular function and pulmonary capillary wedge pressure, the most probable site of etiology seemed to be the pulmonary vasculature. All the common possible secondary causes of PAH were ruled out, but during the investigations, she was found to have elevated thyroid function tests compatible with the diagnosis of Grave's disease. The treatment of Grave's disease, initially by medications and subsequently by radioiodine therapy, was associated with a significant reduction in the pulmonary artery systolic pressure. The purpose of this case report is to highlight one of the unusual and underdiagnosed presentations of Grave's disease.

    Full Text Available Commemoration of the dead is intricately linked to the history of civilization itself. Consequently, art history (understood in a broad sense, encompassing architectural history, social history of art, aesthetics, political iconography, etc. is characterized by a long tradition of paying minute attention to Christian and profane iconography of chapels, epitaphs, and death dances; and to memorials, tombs, and other manifestations, particularly with regard to the Middle Ages and Early Modern Times. Twentieth century war graves, war cemeteries, memorial shrines, and burial sites of the fallen, however, have received only little attention. This assessment was the starting point of our joint endeavor: If the history of conflicts and wars, and the history of war death in particular, is such a major topic for the humanities at large, and especially for contemporary and cultural history, memory studies, etc., then the question arises to what degree art history can contribute to that ongoing discourse.

  16. A possible connection between post-subduction arc magmatism and adakite-NEB rock association in Baja California, Mexico

    Castillo, P. R.

    2007-05-01

    Late Miocene to Recent arc-related magmatism occurs in Baja California, Mexico despite the cessation of plate subduction along its western margin at ~12.5 Ma. It includes calcalkaline and K-rich andesites, tholeiitic basalts and basaltic andesites, alkalic basalts similar to many ocean island basalts (OIB), magnesian and basaltic andesites with adakitic affinity (bajaiites), adakites, and Nb-enriched basalts (NEB). A popular model for the close spatial and temporal association of adakite (plus bajaiite) and NEB in Baja California is these are due to melting of the subducted Farallon/Cocos plate, which in turn is caused by the influx of hot asthenospheric mantle through a window created in the subducted slab directly beneath the Baja California peninsula [e.g., Benoit, M. et. al. (2002) J. Geol. 110, 627-648; Calmus, T. et al. (2003) Lithos 66, 77-105]. Here I propose an alternative model for the cause of post-subduction magmatism in Baja California in particular and origin of adakite-NEB rock association in general. The complicated tectonic configuration of the subducting Farallon/Cocos plate and westward motion of the North American continent caused western Mexico to override the hot, upwelling Pacific mantle that was decoupled from the spreading centers abandoned west of Baja California. The upwelling asthenosphere is best manifested east of the peninsula, beneath the Gulf of California, and is most probably due to a tear or window in the subducted slab there. The upwelling asthenosphere is compositionally heterogeneous and sends materials westward into the mantle wedge beneath the peninsula. These materials provide sources for post-subduction tholeiitic and alkalic magmas. Portions of tholeiitic magmas directly erupted at the surface produce tholeiitic lavas, but some get ponded beneath the crust. Re-melting and/or high-pressure fractional crystallization of the ponded tholeiitic magmas generate adakitic rocks. Alkalic magmas directly erupted at the surface

    Full Text Available Mexico’s business structure has been characterized by the presence of microenterprises, particularly those averaging two workers, representing 65% of establishments in 2008 and 18% of employment. This makes them important for equity and welfare improvement of their members. This paper analyzes the performance of a group of 227 microenterprises in the state of Baja California, by the use of a practical application of the concept of learning curve arranged to incorporate returns to scale. The results indicate that in 48% of cases there is evidence of learning processes and 58% exhibited increasing returns to scale. This allows evaluating the development potential of these microenterprises and the design and implementation of proactive programs that encourage their learning and consolidation in the market.

  3. Facts and fallacies about radioactive iodine therapy for Graves' disease

    The therapeutic options available in the hyerthyroidism of Graves' disease are two basic treatments. Firstly antithyroid drugs and secondly one can 'ablate' the thyroid gland by means of thyroidectomy or radioactive iodine ( 131 I). At present 131 I is the current treatment of chioce for Graves' disease. In a follow-up study of 21 714 patients who were treated with 131 I and observed for a period of 8 years, there was no increase in the incidence of thyriod carcinoma. A possible explanation for this is that the dose of 131 I used destroys the ability of the thyroid cells to replicate and thus transmit genetically damaged material

    It has been increasingly suggested that specific microRNAs expression profiles in the circulation and atrial tissue are associated with the susceptibility to atrial fibrillation. Nonetheless, the role of circulating microRNAs in Graves' disease patients with atrial fibrillation has not yet been well described. The objective of the study was to identify the role of circulating microRNAs as specific biomarkers for the diagnosis of Graves' disease with atrial fibrillation. The expression profiles of eight serum microRNAs, which are found to be critical in the pathogenesis of atrial fibrillation, were determined in patients with Graves' disease with or without atrial fibrillation. MicroRNA expression analysis was performed by real-time PCR in normal control subjects (NC; n = 17), patients with Graves' disease without atrial fibrillation (GD; n = 29), patients with Graves' disease with atrial fibrillation (GD + AF; n = 14), and euthyroid patients with atrial fibrillation (AF; n = 22). Three of the eight serum microRNAs,i.e., miR-1a, miR-26a, and miR-133, had significantly different expression profiles among the four groups. Spearman's correlation analysis showed that the relative expression level of miR-1a was positively correlated with free triiodothyronine (FT3) and free thyroxine (FT4), and negatively related to thyroid stimulating hormone. Spearman's correlations analysis also revealed that the level of miR-1a was negatively correlated with a critical echocardiographic parameter (left atrial diameter), which was dramatically increased in GD + AF group compared to GD group. Furthermore, the receiver-operating characteristic curve analysis indicated that, among the eight microRNAs, miR-1a had the largest area under the receiver-operating characteristic curves not only for discriminating between individuals with and without Graves' disease, but also for predicting the presence of atrial fibrillation in patients with Graves' disease. Our findings

    Graves' disease is the most frequent cause of hyperthyroidism in iodine-sufficient geographical areas and is characterized by the presence in patients' serum of autoantibodies directed against the thyrotropin receptor (TRAb) that cause overproduction and release of thyroid hormones. Clinical presentation results from both hyperthyroidism and underlying autoimmunity. The diagnosis is based on characteristic clinical features and biochemical abnormalities. If serum thyrotropin (TSH) is low, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations should be measured to distinguish between subclinical (with normal circulating thyroid hormones) and overt hyperthyroidism (with increased circulating thyroid hormones). Graves' disease is treated with any of three effective and relatively safe initial treatment options: antithyroid drugs (ATDs), radioactive iodine ablation (RAIU), and surgery. Total thyroidectomy is favored in several clinical situations, such as intolerance, ineffectiveness or recurrence after ATD treatment, radioiodine therapy contraindicated, documented or suspected thyroid malignancy, one or more large thyroid nodules, coexisting moderate-to-severe active Graves' orbitopathy, women planning a pregnancy within 6 months. Whenever surgery is selected as treatment, selection of an expert high-volume thyroid surgeons is fundamental and careful preoperative management is essential to optimize surgical outcomes. Pretreatment with ATDs in order to promptly achieve the euthyroid state is recommended to avoid the risk of precipitating thyroid storm during surgery. For the majority of patients, euthyroidism is achieved after few weeks of ATD treatment. Beta-blockers, such as propranolol, are often added effectively to control hyperthyroid symptoms. Saturated solution of potassium iodide (SSKI) or potassium iodine (Lugol's solution), given for a short period prior to surgery, in order to reduce both thyroid hormone release and thyroid gland

    To reduce intraoperative and postoperative complications, using Lugol solution to preoperatively prepare patients with Graves' disease has (1) rapidly reduced the severity of thyrotoxicosis and (2) reduced the vascularity of the thyroid gland. The vascularity reduction normally accompanies reducing the severity of thyrotoxicosis. However, the effects and mechanism of Lugol solution for reducing blood flow have not been well investigated in the patients with euthyroid (normally functioning thyroid) Graves' disease. Twenty-five patients with euthyroid Graves' disease being preoperatively treated with Lugol solution for 10 days were measured, at baseline and on the operative day, for (1) superior thyroid artery blood flow; (2) systemic angiogenic factor (VEGF); and (3) systemic inflammatory factor [interleukin (IL)-16]. All three parameters were significantly (p Graves' disease. We recommend routine preoperative Lugol solution treatment for all patients with Graves' disease.

    Graves ophthalmopathy is a chronic, multisystem, autoimmune disorder characterized by increased volume of intraorbital fat and hypertrophic extraocular muscles. Proptosis, impaired ocular motility, diplopia, lid retraction, and impaired visual acuity are treated with orbit decompression and fat reduction. The authors present the addition of skeletal augmentation to further improve periorbital aesthetics. Through a transconjunctival with lateral canthotomy incision, a balanced orbital decompression was executed, removing medial and lateral walls and medial floor. Intraorbital fat was excised. All patients underwent placement of porous polyethylene infraorbital rim implants and midface soft-tissue elevation, increasing inferior orbital rim projection and improving the globe-cheek relationship. From 2009 to 2012, 13 patients (11 female and two male; 26 eyes) with Graves ophthalmopathy underwent surgery at two institutions. Outcomes were evaluated for improvements of proptosis, diplopia, dry eye symptoms, and cosmetic satisfaction. Postoperative follow-up ranged from 0.5 to 3 years (median, 1.5 years). The mean improvement on Hertel exophthalmometry was 5.4 mm. Diplopia resolved in three patients (23 percent). No patients had worsening diplopia, and 12 (92 percent) discontinued use of eye lubricants. All patients had cosmetic satisfaction. One patient suffered temporary inferior orbital nerve paresthesia. There were no infections, hematomas, or ocular complications. Skeletal augmentation is a useful adjunct to orbital decompression and fat excision for treating Graves ophthalmopathy. Balanced orbital decompression with infraorbital rim implants is reliable, effective, and safe, with good, lasting results. Resolution of ocular symptoms is improved, as are the patient's personal well-being and social life, with a high-benefit-to-low-risk. Therapeutic, IV.

    Directory of Open Access Journals (Sweden)

    Julio Ruiz Berrrio

    2001-01-01

    Full Text Available El autor considera que una de las características más acusadas en la evolución de los estudios de enseñanza secundaria en España ha sido la primacía concedida a la instrucción sobre los aspectos formativos. Se recuerda que el Bachillerato nació en España con una decidida voluntad de proporcionar mayor número de conocimientos a las clases privilegiadas, especialmente a la burguesía, y que este talante se ha mantenido a través del siglo y medio siguiente. En ese tiempo han variado mucho los planes de estudio, las leyes, los reglamentos; han evolucionado bastante menos los espacios y los tiempos escolares; se han renovado poco los edificios y el mobiliario; se han hecho algunas innovaciones en el currículo; se han alternado diferentes ideologías en el poder, pero tanto para la Administración como para las fuerzas vivas la adquisición de conocimientos, la instrucción, ha sido el parámetro estrella de las sucesivas refonnas de la enseñanza secundaria. En muy pocas ocasiones una concepción annónica de los estudios de secundaria ha pennitido tener en cuenta la necesidad de desarrollo tanto cognitivo como afectivo, moral, físico, etc.; y, cuando así ha sido, hay que reconocer que la sugerencia venía de los particulares, como en el caso del Instituto-Escuela.

    Objective: To study the therapeutic effect and find new ways on treatment of Grave's hyperthyroidism in youngsters. Methods: 260 Grave's hyperthyroidism patients (age under 21 years) treated with 131 I were followed up 1-16 years later. Results: 118 of all patients were cured and 55 cases improved, failed treatment 2 cases, subclinical hypothyroidism 9 cases, clinical hypothyroidism 6 cases. 35 cases were treated with 131 I two or three times. All the patients with subclinical hypothyroidism and clinical hypothyroidism caused by 131 I were cured with medicine. 131 I treatment had no effect on growth and mentality and didn't cause leukemia nor thyroid cancer. Conclusions: The therapy of youngsters with Grave's hyperthyroidism with 131 I has the same effectiveness as adult.

    Full Text Available Abstract Cardiac failure is an uncommon complication of juvenile hyperthyroidism. We describe an adolescent boy with Graves' disease who developed manifestations of heart failure while on antithyroid medications. There was no evidence of any underlying cardiac disease. He had paradoxical euthyroid hormone profile which rose to hyperthyroid range when the manifestations of the cardiac failure subsided. The case highlights several unusual features of Graves' disease.

    Full Text Available Las vías terrestres son la principal herramienta para el desarrollo comercial y económico de una región. La falla de un puente en un proyecto vial genera la interrupción total del tráfico de bienes en su superficie, produciendo cuantiosas e incalculables pérdidas mientras se restituye el normal flujo vehicular. Antioquia cuenta con una de las redes viales secundarias más extensas del territorio colombiano, y en ella hay un número importante de puentes que conforman su patrimonio vial. Gran porcentaje de estos puentes no han recibido un mantenimiento adecuado desde su construcción posibilitando la aparición de fallas en su estructura e incluso su eventual colapso. El inventario realizado a la totalidad de puentes de las vías secundarias del departamento de Antioquia identificó los principales parámetros físicos del puente, su tipología constructiva, el tipo de estructura y el nivel de daños presentado. Como resultado se observa que la tipología estructural más empleada es la de puentes de concreto reforzado, con una longitud de mayor repetición entre 5m y 10m, de los cuales el 11 % requiere una intervención inmediata por el nivel de daños presentados y el 48 % de ellos se encuentran funcionando adecuadamente.

    Graves' ophthalmopathy is characterized by hyperthyroidism, which is associated with higher serum T 3 levels than T 4 due to deiodinase enzymes.The effect of Graves' patient's sera (n=52) with elevated thyroid hormone and TSH receptor or thyroid peroxidase antibody (anti-TPO) levels was investigated on thyroidal, skeletal and eye muscle type 2 deiodinase enzyme (DII) activities. DII activities were measured with 125 I-T 4 substrate, while thyroid hormone and antibody levels with immunoassays.In Graves' ophthalmopathy, sera with elevated FT 4 or FT 3 levels reduced DII activites remarkably in all tissue fractions. Thyroidal DII activities were lower than those using eye muscle fraction (0.6±0.22 vs 1.14±0.43 pmol/mg/min, PEffect of sera with increased FT 3 levels demonstrated also reduced DII activities in patients with Graves' ophthalmopathy after methimazole therapy compared to those who had no ophthalmopathy (2.88±2 vs 20.42±11.82 pmol/mg/min, PHyperthyroid sera with TSH receptor antibodies resulted in increased DII activities, while sera with anti-TPO antibodies were connected to lower DII activities in Graves' ophthalmopathy.In summary, the actions of hyperthyroid sera derived from patients with Graves' disease were tested on tissue-specific DII activities. Elevated FT 4 level-induced DII inactivation is present in Graves' ophthalmopathy, which seems to be also present at the beginning of methimazole therapy. Stimulating TSH receptor antibiodies increased DII activities via their nongenomic effects using sera of hyperthyroid Graves' ophthalmopathy, but anti-TPO antibodies could influence DII activities via altering FT 4 levels. © Georg Thieme Verlag KG Stuttgart · New York.

    Electrical resistivity surveys have proven useful for locating clandestine graves in a number of forensic searches. However, some aspects of grave detection with resistivity surveys remain imperfectly understood. One such aspect is the effect of seasonal changes in climate on the resistivity response of graves. In this study, resistivity survey data collected over three years over three simulated graves were analysed in order to assess how the graves' resistivity anomalies varied seasonally and when they could most easily be detected. Thresholds were used to identify anomalies, and the ‘residual volume' of grave-related anomalies was calculated as the area bounded by the relevant thresholds multiplied by the anomaly's average value above the threshold. The residual volume of a resistivity anomaly associated with a buried pig cadaver showed evidence of repeating annual patterns and was moderately correlated with the soil moisture budget. This anomaly was easiest to detect between January and April each year, after prolonged periods of high net gain in soil moisture. The resistivity response of a wrapped cadaver was more complex, although it also showed evidence of seasonal variation during the third year after burial. We suggest that the observed variation in the graves' resistivity anomalies was caused by seasonal change in survey data noise levels, which was in turn influenced by the soil moisture budget. It is possible that similar variations occur elsewhere for sites with seasonal climate variations and this could affect successful detection of other subsurface features. Further research to investigate how different climates and soil types affect seasonal variation in grave-related resistivity anomalies would be useful.

    Radioactive 131I is currently reported to be a potential effective intervention for Graves' Disease treatment in China. Whether 131I treatment was associated with effective outcome or reduced risk of side effects, reccurence rate remained unknown. Eligible studies were selected from Chinese VIP, Wangfang, CNKI databases using the keywords "Iodine" and "Graves Disease". Finally, 13 clinical trials met the inclusion criterion and were included this meta-analysis. Our meta-analysis included 1355 patients diagnosed of Graves' Disease with regular anti-thyroid drugs oral administration and 1320 patients with 131I therapy. The results showed that there was significant symptom improvement with radioactive iodine intervention (Odd Ratio (OR)=4.50, 95% CI [3.55, 5.71], PGraves' Disease. Treatment with 131I was associated with better clinical outcome; it reduced side effects and reccurence rate but increased hypothyroidism in Graves' Disease.

    Objective: To perform literature search and review on the controversial relationship between therapies of hyperthyroidism due to Graves' disease (GD) and the course of Graves' ophthalmopathy (GO). Methods: We searched the database of MEDLINE (1966-2006.3), EMBASE (1984-2005), Cochrane Library(2006 No. 1), CBMdisc (1978.1-2006.4) and CNKI (1994-2006). The methodological quality of the studies selected for review was assessed according to the quality assessment criteria suggested by the Cochrane systematic review guideline. Meta-analysis was performed by RevMan 4.2 software. Results: Eight studies were included in the systematic review. Meta-analysis showed that there was statistically significant difference between mi and other forms of therapy [surgery or antithyroid drugs (ATD)] (test value: 2.31, 5.97, 3.70, 5.55; all P 0.05). There were not yet any studies on the impact between early prevention of hypothyroidism after mi therapy and GO. Conclusions: Based on meta-analysis on literature data, if early measures are not performed to prevent hypothyroidism after mi therapy, it may induce or aggravate GO more frequently than ATD or surgical treatment. Symptomatic relief of GO after 131 I therapy is also less effective than the other 2 forms of therapy. Therefore, 131 I therapy should be delivered carefully in those patients with GO. (authors)

    The aim of this study was to evaluate the safety, feasibility, effectiveness, and cosmesis of a gasless endoscopic-assisted thyroidectomy via the anterior chest in patients with Graves' disease. We retrospectively reviewed 38 patients with Graves' disease treated with thyroidectomy from November 2007 to June 2015. We analyzed clinical characteristics of patients, type of operation, operative indications, operative duration, length of postoperative hospital stay, and postoperative complications. The thyroidectomies were classified as total thyroidectomy (n = 12) or near-total thyroidectomy with a remnant of Graves' disease is a safe, feasible, and effective and provides an excellent cosmetic outcome procedure. It is a valid option in appropriately selected patients.

    Thyroid dermopathy is not a frequent feature of hyperthyroid Graves' disease, being present in less than 5% of the patients. Graves' disease has been shown to exist in euthyroid or hypothyroid forms in untreated patients. Here, we describe a case of hypothyroid Graves' disease with elephantiasis nostras verrucosa (ENV), which is an extreme form of thyroid dermopathy (TD). A 58-year-old female patient was admitted to the emergency department with somnolence, hypothermia, and bradycardia. Her mental status gradually worsened, resulting in a deep coma. She was intubated and followed in the intensive care unit, as she needed mechanical ventilatory assistance due to respiratory failure. She also had bilateral non-pitting edema, a cobblestone-like appearance, and hyperkeratotic greenish-brown-colored lesions in the pretibial and dorsal regions of the feet that were compatible with ENV. Hypothyroid Graves' disease is a very rare condition among autoimmune thyroid disorders, and ENV is an extremely rare form of TD. Here, we present a patient with hypothyroid Graves' disease and ENV.

    The evidence that stress may provoke Graves' hyperthyroidism in genetically susceptible subjects is substantial. Whether exposure to stress is related to the severity of thyrotoxicosis has not been studied. Advancing age is associated with not only less severe Graves' hyperthyroidism but also self-reported stress. We tested the hypothesis whether advancing age is associated with less exposure to stress, resulting in a lower immunological response, and less severe Graves' hyperthyroidism. Cross-sectional multicenter study. Two hundred and sixty-three consecutive untreated patients with a first episode of Graves' hyperthyroidism were included. The severity of Graves' hyperthyroidism was evaluated biochemically (freeT(4)-index and freeT(3)-index, thyrotropin-binding inhibitory immunoglobulin (TBII)) and clinically by the hyperthyroid symptom scale score (HSS score). Stress exposure was quantitated by three questionnaires. Advancing age was associated with less severe Graves' hyperthyroidism, both biochemically by lower serum freeT(3)-index and freeT(4)-index (Phyperthyroidism. Advancing age was associated with lower scores for stress exposure. Multivariate regression analysis showed that HSS score was independently related to the tendency to report negative feelings (Phyperthyroidism. Because no direct relationship exists between stress exposure and TBII or freeT(3)-index and freeT(4)-index, we reject our hypothesis that less stress is causally related to biochemically less severe Graves' hyperthyroidism in old age. HSS score is primarily determined by negative feelings and not by age.

    Hypothyroidism is a well recognized complication of 22q11.2 deletion syndrome. Auto-immune hyperthyroidism is less common. We report three patients with a 22q11.2 deletion and Graves' disease diagnosed at age 17, 14 and 11 years, respectively. The clinical and biological presentation was typical for auto-immune hyperthyroidism. Graves' disease should be periodically sought during the follow-up program of patients with 22q11.2 deletion syndrome.

    Aim of this study was a characterization of radioiodine therapy (RIT) failures in Graves' disease without simultaneous carbimazole. Method: 226 patients with a confirmed diagnosis of Graves' disease received 686.8 ± 376.4 MBq of iodine-131 orally for thyroid ablation. Target dose was 250 Gy. All patients were followed up for 6 months. Therapy failures were compared with successes regarding possible influencing variables initial thyroid volume, thyroid function, immune activity (TRAb), I-131 uptake, effective half-life, absorbed energy dose, age and gender. Results: 212 of 226 patients (93.8%) were treated successfully, 14 (6.2%) showed a hyperthyroidism relapse within 6 months which required a second radioiodine therapy. A success rate of 92.5% (62/67) could also be achieved with 67 patients who were hyperthyroid at the time of RIT. Compared to the therapy successes, the 14 failures achieved significantly lower absorbed doses (223.8 ± 76.6 Gy vs. 285.2 ± 82.1 Gy, p 0.2). Of the 14 failures, n = 8 reached an absorbed dose 250 Gy. Stepwise logistic regression revealed only absorbed energy dose as a variable significantly influencing therapy success (p 0.2) or gender (p = 0.13). Two-tailed Fisher's exact test showed no significant influence of gender on success rates (failures/successes: male 1/36, female 13/176, p = 0.48). Conclusions: Except for the absorbed energy dose, no other significant variable influencing the outcome of radioiodine therapy in Graves' disease without simultaneous carbimazole could be found. It should be noted, though, that 5 therapy failures (2.2%) reached an absorbed energy dose of >250 Gy. (orig.) [de

    Full Text Available OBJETIVO: Analisar perfil epidemiológico da morbidade materna grave/near miss em uma maternidade pública de referência regional, utilizando diferentes critérios identificadores. MÉTODOS: Trata-se de um estudo descritivo de corte transversal dos casos de morbidade materna grave/near miss realizado em Hospital de referência regional entre junho e outubro de 2009, identificados a partir dos livros de registro de internação da maternidade e análise dos prontuários clínicos. Foram estudadas mulheres que, durante a gestação, parto ou puerpério, apresentaram qualquer quadro clínico compatível com os critérios definidores de morbidade materna grave/near miss de Waterstone et al., Mantel et al. e Organização Mundial de Saúde. RESULTADOS: Entre as 1.544 internações foram identificadas 89 mulheres com morbidade materna grave, considerando os critérios adotados. As razões de morbidade materna grave/near miss variaram entre 81,4 a 9,4 por 1.000 NV, dependendo do critério utilizado. O índice de Mortalidade foi de 3,2%, chegando a 23% no critério da OMS. Das 89 mulheres, apenas 40% fizeram mais de seis consultas de pré-natal e 10% não realizaram qualquer consulta. Os marcadores mais encontrados foram a pré-eclâmpsia grave seguida de hemorragia grave, internação em UTI, Síndrome HELLP e eclâmpsia. Ocorreram três mortes maternas por causas obstétricas com RMM de 280/100.000 NV e uma morte tardia. O critério da OMS se mostrou mais específico, identificando os casos mais graves, enquanto o de Waterstone foi mais sensível. CONCLUSÃO: O estudo da morbidade materna grave/near miss em um hospital de referência regional pode contribuir para o conhecimento da magnitude deste evento, como também identificar suas características e condições clínicas mais frequentes, sendo extremamente importante para o enfrentamento da morbi-mortalidade materna.OBJECTIVE: To investigate severe maternal morbidity/near misses in a tertiary

    To determine the factors associated with 20 minute Tc-99m pertechnetate thyroid uptake, we examined all patients in whom thyrotoxicosis was diagnosed at Chiba-Hokusoh Hospital, Nippon Medical School from 2001 April through 2003 March. Patients with thyrotoxicosis diagnosed during this period were 57 with Graves' disease (76%), 11 with transient hyperthyroxinemia (TH) (14.7%), and 7 with subacute thyroiditis (SAT) (9.3%). The uptake of Tc-99m ranged from 0.97% to 40.1% in Graves' disease and from 0.15% to 0.8% in TH. Although TH may include spontaneous resolution of Graves' disease as well as painless thyroiditis, no treatment was necessary for these patients. Uptake in all patients with SAT was less than 0.5%. There were significant correlations between the level of Tc-99m uptake and the levels of free triiodothyronine (fT3), free thyroxine (fT4), thyroid-stimulating hormone (TSH)-binding inhibitory immunoglobulin (TBII), and thyroid stimulating antibody (TSAb) in patients with Graves' disease. Older patients with Graves' disease showed lower uptake than did younger patients. Both Tc-99m pertechnetate uptake and TBII levels, but not fT3, fT4 or TSAb levels, at the beginning of antithyroid drug treatment correlated significantly with the duration of treatment until the daily dose of methimazole reached 5 mg. These data suggest that Tc-99m pertechnetate uptake reflects the severity of Graves' disease and its response to the medical treatment and that antithyroid drug therapy is not necessary when the uptake is less than 0.9%.

    Depression in a common, life-threatening complication of Cushing's syndrome and may occur in several other endocrine disorders. It is not clear, however, whether distinct features pertain to hypercortisolism. We studied depression in Cushing's syndrome differentiating pituitary-dependent and pituitary-independent forms, its incidence compared to Graves' disease, and its appearance in the prodromal phase of both conditions. To 66 consecutive patients with Cushing's syndrome and 70 with Graves' disease, after treatment, a semistructured interview for depressive symptoms based on Paykel's clinical interview for depression was administered. In Cushing's syndrome, the response of depression to normalization of urinary cortisol levels was evaluated by Kellner's global rating method. There was a significant difference in the occurrence of depression (p Cushing's syndrome (62%) and Graves' disease (23%). Depression appeared in the prodromal phase in 27% of patients with Cushing's syndrome and in 14% of those with Graves' disease, but the difference was not significant. In Cushing's syndrome, there were no significant differences in depression between patients with pituitary-dependent (n = 41) and pituitary-independent (n = 20) forms, or in their response to treatment. About 70% of patients fully recovered from their depression, whereas there was no substantial change in the others and even worsening in 2. Our findings in Cushing's syndrome and Graves' disease are in agreement with previous investigations using specific diagnostic criteria for depression. We found a tendency for this symptom to manifest in the prodromal phase of both illnesses. An endocrine etiology should be, therefore, considered in depressed patients not responding to standard psychiatric treatment.

    Objective: To evaluate the long-term outcome and the sequelae of Graves' orbitopathy treated with radiotherapy, and to specify the prognostic factors. Methods: From 1979 to 1999, 104 patients with progressive Graves' orbitopathy were treated with conventional orbital radiotherapy. Post globe and pituitary irradiation of 25-35 Gy was given to 56 patients, which was followed by a boost of 15-20 Gy to the pituitary. Follow-up time was 7.5 - 25.0 years. The result of radiotherapy was analyzed. Results: Overall response rate was 71.1%. The response rate of patients with soft-tissue infiltration, corneal involvement, proptosis, sight loss and extraocular muscle dysfunction was 88.4%, 75.1%, 55.6%, 68.8% and 64.4%, respectively. Twelve patients (11.5%) developed cataracts 2.5-18.3 years (median 11.2 years) after irradiation. One patient developed left-eye retinopathy 3.2 years after irradiation. No patient developed secondary tumor within the irradiation field. Conclusions: Orbital radiotherapy for progressive Graves' orbitopathy, being effective and safe, can control the disease progression and improve the symptoms. The side effect of radiotherapy is fewer than other treatment modalities. (authors)

    Objective: The clinical value of thyrotrophin receptor antibody (TRAb) in patients with Graves' hyperthyroidism was investigated during 131 I radiotherapy. Methods: A total of 130 patients with Graves' hyperthyroidism and 50 normal controls were included in the study. Serum concentration of TRAb was measured by radioreceptor assay (RRA) before and at 3, 6, 12 and 24 months after 131 I radiotherapy. Results: Abnormally higher TRAb level [(92.93±68.99)U/L] was noted in patients before treatment(P 131 I radiotherapy, the TRAb [(12.99±5.52) U/L] was back to normal with no difference to that of controls (P>0.05). Conclusion: Serum concentration of TRAb was of clinical significance in the diagnosis of Graves' hyperthyroidism and in the monitoring of 131 I radiotherapy. (authors)

    Full text: Detection of autoantibodies to the TSH receptor by radioreceptorial assays (RRA) is largely requested in clinical practice for the diagnosis of Graves' disease and its differentiation from diffuse thyroid autonomy. Additionally, TRAb measurement during antithyroid drug treatment can be useful to evaluate the risk of disease's relapse alter therapy discontinuation. Nevertheless, some patients affected by Graves' disease are TRAb negative when 1st generation assay is used. Recently a new RRA method for TRAb assay was developed by using human recombinant TSH-receptor and solid-phase technique. Aim of our work was the comparison between 1st and 2nd generation TRAb assays in Graves' disease patients and, particularly, the evaluation of 2nd generation test in a sub-group of patients affected by Graves' disease but with negative 1st generation TRAb assay. We evaluated the diagnostic performance of a newly developed 2nd generation TRAb assay (DYNOtest(r) TRAK human, BRAHMS Diagnostica GmbH, Germany) in 46 patients affected by Graves' disease with negative 1st generation TRAb assay (TRAK Assay(r), BRAHMS Diagnostica GmbH, Germany) . A control groups of 50 Graves' disease patients with positive 1st generation TRAb assay, 50 patients affected by Hashimoto's thyroiditis and 50 patients affected by nodular goiter were also examined. 41 out of 46 patients affected by Graves' disease with negative 1st generation TRAb assay showed a positive 2nd generation test. The overall sensitivity of the 2nd generation test was significantly improved respect the 1st generation assay in Graves' disease patients (χ 2 = 22.5, p<0.0001). 1 and 3 out of 50 patients affected by Hashimoto's thyroiditis were positive by 1st and 2nd generation TRAB assay, respectively. All these patients showed primary hypothyroidism. No differences resulted in euthyroid Hashimoto's thyroiditis sub-group and in nodular goiter control group. The 2nd generation TRAB assay is clearly more sensitive than the 1

    The aim of this retrospective study was to assess the long-term outcome of a personalized dosimetry approach in Graves' disease aiming to render patients euthyroid from a planned thyroid absorbed dose of 60 Gy. A total of 284 patients with Graves' disease were followed prospectively following administration of radioiodine calculated to deliver an absorbed dose of 60 Gy. Patients with cardiac disease were excluded. Outcomes were analysed at yearly intervals for up to 10 years with a median follow-up of 37.5 months. A single radioiodine administration was sufficient to render a patient either euthyroid or hypothyroid in 175 (62%) patients, the remainder requiring further radioiodine. The median radioactivity required to deliver 60 Gy was 77 MBq. Less than 2% patients required 400-600 MBq, the standard activity administered in many centres. In the cohort receiving a single administration, 38, 32 and 26% were euthyroid on no specific thyroid medication at 3, 5 and 10 years, respectively. Larger thyroid volumes were associated with the need for further therapy. The presence of nodules on ultrasonography did not adversely affect treatment outcome. A personalized dosimetric approach delayed the long-term onset of hypothyroidism in 26% of patients. This was achieved using much lower administered activities than currently recommended. Future studies will aim to identify those patients who would benefit most from this approach.

Para lograr ese objetivo, se analiza la información de las Encuestas Demográficas de Baja California de 1986 y 1990 con el modelo de los determinantes próximos de la fecundidad. Los resultados de dicho análisis muestran, por una parte, que los patrones reproductivos de la población migrante y no-migrante son c1aramentediferenciados (tanto en términos de fecundidad ilegítima como de formación de uniones, de sus prácticas anticonceptivas y de lactancia postparto, y que de ello se deriva un diferencial de fecundidad que resulta ser 17.5% superior para la población migrante en 1990. Por otra parte, los resultados también permiten estimar que, por cada tres nuevos inmigrantes que por año recibe la entidad, la inmigración acumulada aporta dos nuevos residentes con los nacimientos generados por las mujeres migrantes. Dada la magnitud que adquieren esos procesos (i.e. 59 mil nuevos habitantes por año ~ total, se concluye sugiriendo líneas generales de acción que permitan adecuar la política de población a las condiciones específicas de Baja California

    Prediction and early diagnosis of orbitopathy is needed in patients with Graves' disease, especially when radioiodine therapy is planned. Positron emission tomography/computerized tomography (PET/CT) using flourine-18-fluorodeoxyglucose (FDG) is an effective imaging modality in detection of inflammation, however, its ability to detect orbital inflammation has not been well studied. The aim of our study is to determine the ability of FDG PET/CT to detect orbital inflammation related with Graves' disease, identify active orbitopathy, predict the radioiodine-triggered orbitopathy, and find out the effects of radioiodine on orbital inflammation. Total 31 Graves' disease patients and 17 controls were included. All Graves' disease patients underwent cranial FDG PET/CT imaging prior therapy. Radioiodine therapy and post-treatment PET/CT study was applied to 21 patients. PET/CT images of all examinees were evaluated, measuring extraocular muscle maximum standard uptake value (SUVmax) and muscle thickness. FDG uptake was increased in the majority of extraocular muscles in Graves' disease patients in comparison to controls and this increase was found to be irrelevant from muscle thickness. Extraocular muscle SUVmax values did not increase in Graves' orbitopathy patients who received radioiodine under corticosteroid prophylaxis. SUVmax level of all orbital rectus muscles were increased after radioiodine therapy in nonsmokers, whereas no increase was detected in smokers. FDG PET/CT may be helpful in detection of extraocular muscle inflammation and it may show ongoing orbitopathy in early stages of inflammation before anatomical changes occur.

    Full Text Available The works of Sir James George Frazer had an outstanding influence on the literature of modernism. Among those who benefited from Frazer’s ritualism were W. B. Yeats, T. S. Eliot. James Joyce, Ernest Hemingway, D. H. Lawrence, Ezra Pound, Mary Renault, Joseph Campbell, Robert Graves and many others. Robert Graves was known for his famous adaptation of Frazer’s concept of the sacred king who is sacrificed for the benefit of his subjects thus forming the narrative frame for the one of his most controversial novels. The dying king is also identified with the poet striving to attain the favour of the Triple Muse Goddess - who represents the embodiment of true poetic inspiration. The aforementioned concept is not the only thing that Graves inherited from his famous ancestor. In our analysis we laid stress on the customs, rituals, magic symbols and deities both authors dealt with. We also observed a striking resemblance of the style Greves and Frazer developed and their euchemeristic approach to myths as well.

    Flowering plants possess mechanisms that stimulate positive emotional and social responses in humans. It is difficult to establish when people started to use flowers in public and ceremonial events because of the scarcity of relevant evidence in the archaeological record. We report on uniquely preserved 13,700-11,700-y-old grave linings made of flowers, suggesting that such use began much earlier than previously thought. The only potentially older instance is the questionable use of flowers in the Shanidar IV Neanderthal grave. The earliest cemeteries (ca. 15,000-11,500 y ago) in the Levant are known from Natufian sites in northern Israel, where dozens of burials reflect a wide range of inhumation practices. The newly discovered flower linings were found in four Natufian graves at the burial site of Raqefet Cave, Mt. Carmel, Israel. Large identified plant impressions in the graves include stems of sage and other Lamiaceae (Labiatae; mint family) or Scrophulariaceae (figwort family) species; accompanied by a plethora of phytoliths, they provide the earliest direct evidence now known for such preparation and decoration of graves. Some of the plant species attest to spring burials with a strong emphasis on colorful and aromatic flowers. Cave floor chiseling to accommodate the desired grave location and depth is also evident at the site. Thus, grave preparation was a sophisticated planned process, embedded with social and spiritual meanings reflecting a complex preagricultural society undergoing profound changes at the end of the Pleistocene.

  6. Mediastinal neoplasms in patients with Graves disease: a possible link between sustained hyperthyroidism and thymic neoplasia?

    Full Text Available Abstract Background Anterior mediastinal masses are a rare but well documented finding in Graves disease. The vast majority of these lesions represents benign thymic hypertrophy and regress after treatment of the hyperthyroidism. A small percentage of these cases however represent neoplastic/malignant diseases which require further treatment. Cases 12 year old boy with one year history of refractory Graves disease was found to have an anterior mediastinal mass and underwent curative thyroidectomy for sustained hyperthyroidism. Cervical lymphadenopathy was detected during the procedure and biopsy was obtained. A 23 year old woman who presented with a one month history of hyperthyroid symptoms, was diagnosed with Graves disease and also was found to have an anterior mediastinal mass on imaging. Biopsy of the anterior mediastinal mass was obtained and subsequently the patient underwent robotic thymectomy. Histologic examination and immunophenotyping of the cervical lymph node in a 12 year old boy revealed neoplastic proliferation of T lymphoblasts diagnostic of T lymphoblastic leukemia/lymphoma. Examination of the anterior mediastinal mass biopsy in the 23 year old woman revealed type B1 thymoma which was confirmed after examination of the subsequent robotic thymectomy specimen. Conclusion This is the first reported case of T cell lymphoblastic lymphoma and the third reported case of thymoma associated with sustained hyperthyroidism due to Graves disease. These cases indicate that an anterior mediastinal mass in a patient with active Graves disease may be due to a neoplastic cause, which may require definitive treatment. Caution should be exercised when dismissing a mediastinal mass as benign thymic hyperplasia in patients with active Graves disease.

    Women requiring thyroid hormone replacement after definitive therapy (surgery or radioiodine) for Graves' disease who later conceive require an early increase in levothyroxine dose and monitoring of thyroid hormone levels throughout pregnancy. In addition, as TSH receptor antibodies (TRAb) can cross the placenta and affect the fetus, measurement of these antibodies during pregnancy is recommended. To review the management of pregnancies following definitive treatment for Graves' disease in order to assess the rates of maternal hypothyroidism and TRAb measurement. Retrospective chart review of women who had undergone definitive treatment for Graves' disease at a tertiary hospital and subsequently had one or more pregnancies. A total of 29 women were identified, each of whom had at least one pregnancy since receiving definitive treatment for Graves' disease: there were a total of 49 pregnancies (22 in the surgical group and 27 in the radioiodine group). Both groups had high rates of hypothyroidism documented during pregnancy (47 and 50%, respectively). The surgical group was more likely to be euthyroid around the time of conception. Less than half of the women were referred to an endocrinologist or had TRAb measured during pregnancy. Neonatal thyroid function was measured in one-third of live births. One case of neonatal thyrotoxicosis was identified. Adherence to the current American Thyroid Association guidelines is poor. Further education of both patients and clinicians is important to ensure that treatment of women during pregnancy after definitive treatment follows the currently available guidelines. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Objective: To study the feasibility of radioactive treatment of Graves disease with dosimetry of 131 I in novel method by computer. Methods: The database comprised 206 selected Graves disease cases and according to this database the nonlinear functions could be inferred consequently, then 206 Graves disease patients were divided into two groups. The group one, 109 patients, was treated with back-propagation (BP) dosimetry method. The group two was treated with traditional method. The results were analyzed. Results: Group one had an effective rate of 93.5%, cure rate of 90.8%, recurrent rate of 3.6% and early stage of hypothyroidism rate of 3.6%. Group two had an effective rate of 90.7%, cure rate of 85.5%, recurrent rate of 5.1% and early stage of hypothyroidism rate of 5.1%. Conclusion: The BP method is efficient and the results reflect that this method might increase the accuracy of the dosimetry of 131 I and reduce recurrent rate and early stage of hypothyroidism occurrence

    We recently demonstrated that moderate alcohol consumption is associated with a considerable reduction in the risk of autoimmune hypothyroidism, similar to findings in other autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. We aimed to study a possible association between alcohol intake and autoimmune Graves' hyperthyroidism. This is a population-based, case-control study. In a well-defined Danish population (2,027,208 person-years of observation), we prospectively identified patients with new overt thyroid dysfunction and studied 272 patients with Graves' hyperthyroidism. For each patient, we recruited four age-gender-region-matched controls with normal thyroid function (n = 1088). Participants gave detailed information on current and previous alcohol intake as well as other factors to be used for analyses. The association between alcohol intake and development of hyperthyroidism was analysed in conditional multivariate Cox regression models. Graves' patients had a lower reported alcohol consumption than controls (median units of alcohol (12 g) per week: 2 vs 4, P hyperthyroidism. Odds ratios (95% confidence interval) compared with the reference group with a recent (last year) consumption of 1-2 units of alcohol per week were as follows: 0 units/week 1·73 (1·17-2·56), 3-10 units/week 0·56 (0·39-0·79), 11-20 units/week 0·37 (0·21-0·65), ≥21 units/week 0·22 (0·08-0·60). Similar results were found for maximum previous alcohol consumption during a calendar year. No interaction was found with the type of alcohol consumed (wine vs beer), smoking habit, age, gender or region of inhabitancy. Moderate alcohol consumption is associated with a considerable reduction in the risk of Graves' disease with hyperthyroidism--irrespective of age and gender. Autoimmune thyroid disease seems to be much more dependent on environmental factors than hitherto anticipated. © 2012 John Wiley & Sons Ltd.

    The aim of the this study was to evaluate different states in hyperthyroid patients and incidence of hypothyroidism after I-131 therapy.We observed a total of 184 hyperthyroid pts, from which 108(58,7%)pts with Graves' disease,65(35,3%)pts with single toxicum nodule and 11(6%)pts with toxicum multinodular goitre,treated with radioiodine therapy during the period 1986-2001.Dose of I-131 orally administered ranged 150-1100MBq and was calculated according to the 'MBq/gram' method.The radioiodine-131 therapy was performed once in 69,5%(128/184)pts,twice in 21,2%(39/184)pts and in 9,3%(17/184)pts more than two doses. Completely cured of hyperthyroidism occurred in 61%(66/108)pts with Graves' disease,81,8%(9/11)pts with toxic multinodular goiter and 90,7%(59/65)pts with single toxic nodule. The patients in our study were evaluated 6 months to 15 years after received J-131 therapy. Incidence of early hypothyroidism within one year was 23,1%(25/108) in Graves' disease,9%(1/11) in toxic multinodular goiter and 4,6%(3/65) with single toxicum nodule.Overall incidence of hypothyroidism within one year was 17,6% and had cumulative increase of Graves' disease every following year approximately for 3%,while for adenoma toxicum there was no any significant changes. We concluded that radioiodine therapy is simple,comfortable radical method for medical treatment of hyperthyroidism and indicate higher incidence of hypothyroidism in patients treated with I-131 for Graves' disease than that of patients treated for toxicum multinodular goiters and single toxic nodule

    Graves' disease is an autoimmune disorder with various clinical manifestations. Thyrotropin receptor antibodies (TRAbs), the circulating autoantibodies specific to Graves' disease, are the cause for hyperthyroidism, the most prevalent abnormality. Hyperthyroidism leads to increased bone turnover and a negative bone balance. The aims of the present study were to determine the relationship between TRAbs and bone mineral density (BMD), to assess the extent of BMD change in patients with Graves' disease, and to determine the impact of conservative and surgical therapy on BMD. Fifty female postmenopausal patients with Graves' disease were chosen for this study. Twenty women had a recent diagnosis of Graves' disease, 30 women presented with a compensated disease state after either conservative or surgical treatment, and 30 healthy postmenopausal women served as controls. Thyroid parameters were measured, and BMD values were obtained by dual energy x-ray absorptiometry scan.Femoral neck and lumbar spine BMD and T-scores were significantly lower in newly diagnosed patients compared with the control group, but a difference was not observed between the treated and control groups. Statistical analysis revealed a strong and significant negative correlation between femoral neck and lumbar spine BMD and TRAb values.Both surgical and conservative therapies are effective for restoring BMD in postmenopausal patients with Graves' disease, and the increased level of TRAb can be a useful marker of bone density impairment.

    Thyroid cancer and Graves' disease may present simultaneously in one patient. The incidence of the development of hyperthyroidism from metastatic differentiated thyroid carcinoma is rare. We herein report a case of metastatic follicular carcinoma complicated with Graves' disease after total thyroidectomy. A 57-year-old woman underwent right hemithyroidectomy for follicular carcinoma. Metastatic lesions appeared in the lungs and skull two years after the first surgery, and remnant thyroidectomy was performed for radioactive iodine-131 (RAI) therapy, during which the TSH receptor antibody (TRAb) was found to be negative. The patient was treated with RAI therapy four times for four years and was receiving levothyroxine suppressive therapy. Although radioiodine uptake was observed in the lesions after the fourth course of RAI therapy, metastatic lesions had progressed. Four years after the second surgery, she had heart palpitations and tremors. Laboratory data revealed hyperthyroidism and positive TRAb. She was diagnosed with Graves' disease and received a fifth course of RAI therapy. 131I scintigraphy after RAI therapy showed strong radioiodine uptake in the metastatic lesions. As a result, the sizes and numbers of metastatic lesions decreased, and thyroid function improved. Metastatic lesions produced thyroid hormone and caused hyperthyroidism. RAI therapy was effective for Graves' disease and thyroid carcinoma.

    Full Text Available Concrete is known as a porous building material, this can causes materials outside the concrete mass infiltrate into the concrete. Concrete structures constructed around the beach/seashore tend to have deterioration problems due to salt attack. This paper discusses models to predict the service life of concrete structure based on the deterioration problems. The service life of concrete structure is divided into three periods. Period I is time needed by Cl−ion to infiltrate into concrete up to the surface of the reinforcement, period II is time needed by corrosion products to fill the transition zone pores, and period III is deterioration time. The value of parameters used in the proposed equations is derived from the result of experiments. Finally, the proposed equations were evaluated by the relationship between variations of depth of concrete cover, water cement ratio (W/C and distance of structure from shore line with service life. It could be concluded that the results of the prediction is satisfactory. Abstract in Bahasa Indonesia : Beton dikenal sebagai bahan bangunan yang berpori. Sifat ini menyebabkan senyawa dari luar dapat berinfiltrasi ke dalam beton. Bangunan beton yang dibangun di sekitar daerah pantai/laut cenderung mengalami kerusakan akibat serangan garam klorida. Makalah ini mendiskusikan model untuk memprediksi waktu layan bangunan beton terhadap kerusakan akibat korosi baja tulangan. Waktu layan bangunan beton dibagi menjadi tiga periode. Periode I adalah waktu yang dibutuhkan oleh ion Cl− untuk melakukan infiltrasi sampai ke permukaan baja tulangan, Periode II adalah waktu yang dibutuhkan oleh senyawa hasil korosi untuk mengisi pori-pori yang ada di transition zone, dan Periode III adalah waktu kerusakan pada bangunan beton. Parameter-parameter yang digunakan dalam persamaan yang diusulkan ditentukan dari hasil pengukuran di laboratorium. Persamaan tersebut dievaluasi dalam hal hubungan antara variasi tebal selimut beton

    Prolonged worry has generally been acknowledged as one of the main precipitating factors of the onset of Graves' disease. A review of literature reveals that emotional stresses of considerable severity precede the onset of hyperthyroidism in about 90% of cases. However, not everyone subscribes to the Stress/Graves' disease hypothesis. Attempts to resolve this issue have tended to focus on whether a correlation can be shown between the magnitude of antecedent life events and the disease. Hence the main objective of the present study was to identify the possible association between stressful life events and Graves' disease. This paper presents the results of a case-control study, involving patents and subjects from the Veterans Memorial Medical Centre of Manila. A total of 224 patients of Graves' disease, newly or previously diagnosed, representing the 'patient's' arm were interviewed. All patients were questioned regarding various stresses, which greatly affected their life style spanning over a 12-month period prior to the onset of the disease. Simultaneously, 224 control subjects were also interviewed, and their stresses spanning over a similar period preceding the dates of interviews were recorded in quantifiable terms. Different stresses were given different intensity scores based on a social readjustment scale taking into consideration the life situations, emotions and diseases. In cases of multiple stresses, intensity scores were added to obtain the total stress intensity. Results were expressed as mean, standard deviation, median, frequency and percent distribution. Scatter plot was also constructed for intensity of stressful life events. To determine association of different factors with Graves' disease, Students t-test and chi-square tests were applied to the data. Odds ratio (OR) was also computed to determine risk attributed to each factor. Since there was significant difference in gender distribution between the patients and controls, stratified Mantel

    The state of Baja California Sur (Mexico) does not form part of the national interconnected electrical system of the country, reason why is local its electrical power supply; one of the alternatives to cover future demands is the use of gas-based combined cycles, which presents the additional problem of including a high price for gas transportation in its costs. In order to reduce total costs, including investment, fuels and operation and maintenance in the operation of the Baja California Sur state electricity system in the coming years, mainly due to the estimated natural gas cost order of $11.50 dollars per million BTU, a proposal is presented to reduce the costs of the electrical system by replacing the necessary combined cycles with the new Small Modular Reactor type nuclear reactors, this alternative is economically competitive.

    The outcome of 234 patients with Graves' disease treated by subtotal thyroidectomy over a 12-year period is analysed with specific reference to hypothyroidism. Of definite hypothyroid cases, 98% occurred within 2 years. Failure to develop hypothyroidism was statistically related to large remnant size and a large goitre preoperatively. Histological review showed that any degree of lymphocytic infiltration was associated with the development of hypothyroidism (50% vs 22%). Late onset hypothyroi...

    Finding agranulocytosis (AG) at an early stage is important to improve outcome, but periodic granulocyte count monitoring is not generally recommended for patients with Graves' disease, because AG develops suddenly. At the Kuma Hospital, Graves' patients under antithyroid drug (ATD) treatment in an outpatient clinic have a granulocyte count examination during each visit, and if it is Graves' disease were 131 I-radioisotope therapy (19 patients), thyroidectomy (2 patients), inorganic iodine (1 patient), or another ATD (1 patient). Among the 33 GP patients, 31 (94%), including 20 asymptomatic cases, were discovered during periodic granulocyte count monitoring. Most of them stopped ATD, and other treatments for Graves' disease were selected. Periodic monitoring of granulocyte counts is useful for identifying AG and GP patients with no or minimum infection symptoms.

    Graves' disease is an autoimmune disease. It accounts for 50-80% of cases of hyperthyroidism. Antibodies against the TSH receptor (TRAb) are responsible for hyperthyroidism (TRAB). The key role in monitoring and diagnosis of Graves' disease plays the level of hormones of free thyroxine and triiodothyronine. Helpful is an ultrasound of the thyroid scintigraphy which due to its functional character is both a valuable addition to morphological studies as well as plays an important role in the diagnosis and therapy in patients with Graves' disease. There is no perfect treatment for Graves' disease. The reason for this is the lack of therapy directed against primary pathogenic mechanisms. Currently available treatments need to be thoroughly discussed during the first visit as the patient's understanding of the choice of a treatment constitutes a vital role in the success of therapy. Graves' disease treatment is based on three types of therapies that have been carried out for decades including: pharmacological treatment anti-thyroid drugs, I131 therapy and radical treatment - thyroidectomy. The purpose of the treatment is to control symptoms and patient to return to euthyreosis. Treatment of Graves' disease is of great importance because if left untreated, it can lead to long-term harmful effects on the heart, bone and mental well-being of patients.

    Objective: To investigate the mechanism of Graves disease by observing the changes of CD4 + CD25 + CD127 - regulatory T cells (Treg) population in the patients. Methods: Flow cytometry was used to detect the proportion of CD4 + CD25 + CD127 - Treg of CD4 + T cells in 90 Graves disease patients (Graves disease group) and 50 healthy adults (control group). Thyroid function and autoantibody levels were determined simultaneously. The t test was adopted for comparison between groups. The relationship between CD4 + CD25 + CD127 - Treg and thyroid function was analyzed by linear correlation analysis. Results: The percentages of CD4 + CD25 + CD127 - Treg in Graves disease group and control group were 1.39%±1.09% and 4.59%±1.14% separately. There was significant difference between the two groups (t=16.4, P<0.01). There were negative correlation between CD4 + CD25 + CD127 - Treg percentages and total triiodothyronine, total thyroxine,free triiodothyronine, free thyroxine and thyrotropin receptor antibody,thyroglobulin antibody, thyroid microsomal antibody (r=-0.62, -0.65, -0.56, -0.71, -0.50, -0.15, all P<0.01). Conclusions: The reduction of CD4 + CD25 + CD127 - Treg percentages in Graves disease group and close relations of CD4 + CD25 + CD127 - Treg with thyroid function and thyroid autoantibody levels suggest that CD4 + CD25 + CD127 - Treg decrease in the number may be associated with the onset of Graves disease. CD4 + CD25 + CD127 - may be the specific marker of Treg. (authors)

    The effect of selenium supplementation on recurrent hyperthyroidism caused by Graves' disease is unclear. Our study aimed to assess the efficacy of selenium supplementation therapy on recurrent Graves' disease. Forty-one patients with recurrent Graves' disease were enrolled in this study. All patients received the routine treatment using methimazole (MMI), while patients allocated to the selenium group received additional selenium therapy for 6 months. The influence of selenium supplementation on the concentrations of thyroid stimulating hormone (TSH), anti-TSH-receptor antibodies (TRAb), free thyroxine (FT4), and free triiodothyronine (FT3) were assessed. The remission rate was also compared between 2 groups. There was no obvious difference in the demographic data and the levels of serum FT4, FT3, TSH, and TRAb between the 2 groups at baseline. Both FT4 and FT3 decreased more at 2 months in the selenium group than the controls, while the TSH level increased more in patients receiving selenium supplementation (pGraves' disease. Randomized trials with large number of participants are needed to validate the finding above. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Glutamic acid decarboxylase antibodies (GADAs are one of the markers of islet cell autoimmunity and are sometimes present before the onset of type 1 diabetes (T1D. GADA can be present in Graves' patients without diabetes; however, the outcome of GADA-positive Graves' patients is not fully understood, and the predictive value of GADA for the development of T1D in Graves' patients remains to be clarified. We investigated the prevalence of GADA in 158 patients with Graves' disease and detected GADA in 10 patients. They were followed up to discover whether or not T1D developed. In the course of eight years, 2 patients with high titers of GADA developed T1D, both had long-standing antithyroid drug-resistant Graves' disease. Thus, Graves' disease with high GADA titer seems to be at high risk for T1D.

    Background: Radiotherapy (RT) has been proven effective in the management of Graves' orbitopathy in numerous studies. Most commonly is the use of conventional fractionated RT and the value of hypofractionated irradiation has not been investigated. Materials and methods: The results in 33 euthyroid cases who underwent RT with a total dose of 21.0 Gy given in three weekly fractions of 3.0 Gy are retrospectively analyzed. The duration of symptoms ranged from 1-84 months and all of the cases had treatment failure after previous administration of corticosteroids. After a mean follow-up period of 33.6 months the overall results were assessed according to the criteria by Donaldson et al. and for evaluation of the clinical outcome a classification with the main criteria being eye-lid changes, exophthalmos, myopathy and eye nerve involvement was used. Results: At follow-up, the overall response to RT was 84.8% (28/33 cases). The analysis with the clinical classification demonstrated that in 19/33 (57.6%) cases occurred a decrease of eye lid changes and exophthalmos and 12/33 (36.4%) had a relief of myopathy. 2/33 cases (6.0%) developed an eye nerve compression causing the necessity of surgical decompression. 3/33 cases (9.0%) had a progression of at least of one of the single criteria of the score and therefore they were classified as non-responders. Conclusions: Hypofractionated RT has been proven effective for treatment of severe cases of Graves' orbitopathy in cases with a prolongated duration of symptoms. The comparison with literature data demonstrate that the results after hypofractionated RT are comparable to those obtained after conventional fractionated RT. (orig.)

    Experience using low-dose radioiodine given six-monthly instead of yearly in hyperthyroid patients with Graves' disease is reported. One hundred and thirty-five patients have been treated over a three-year period with 74 MBq (2 mCi) doses of 131 I. |Thirty-eight|percent| were controlled with a single dose. Those patients requiring more than one dose were treated with a further 74 MBq (2 mCi) 131 I at six-monthly intervals until euthyroid. Using this approach, 46% were euthyroid one year after starting treatment, and 75% were euthyroid at two years. The incidence of hypothyroidism following treatment was 2.2% at one year, with a yearly incidence thereafter of 4-6%. Six-monthly scheduling of low-dose radioiodine in Graves' disease can reduce the time taken to become euthyroid, compared with conventional yearly low-dose treatments. Further follow up is required to confirm the present low incidence of hypothyroidism following treatment. (author)

    Full Text Available Aim: The aim of our study was to assess the limitation of clinical examination in determining the morphology of thyroid gland in patients with hyperthyroidism and its implications. Methods: A retrospective analysis of consecutive patients with hyperthyroidism seen in a tertiary endocrine clinic were analyzed. Sub-analysis was performed on patients with proven Graves' disease. Results: Of the 133 patients included in this study with hyperthyroidism, 60 (45% patients had significant nodularity on ultrasound (US. However, only 67% of these were identified on clinical examination. In patients with confirmed Graves' disease (n = 73, the discordance between US and clinical examination was very similar (18 of 30 patients, 60%. Conclusion: US should form an essential part of the evaluation of hyperthyroidism as the morphology of thyroid gland could be variable and nodules in these glands would also need to be appropriately investigated. This would also significantly influence decision-making and appropriate immediate and follow-up management plan.

    Graves' ophthalmopathy is an autoimmune process initiated and maintained by antigen(s) shared by the thyroid and the orbit. A matter of argument concerns the choice of the method of treatment for Graves' hyperthyroidism when clinically evident ophthalmopathy is present. Restoration of euthyroidism appears to be beneficial for ophthalmopathy. On the other hand the continuing disease activity associated with the recurrence of hyperthyroidism appears to adversely affect the course of ophthalmopathy. For these reasons it is our opinion that in patients with Graves' hyperthyroidism and ophthalmopathy the permanent control of thyroid hyper function by ablation of thyroid tissue should be obtained by radioiodine therapy or thyroidectomy. The rationale for an ablative strategy is the following: i) permanent control of hyperthyroidism avoids exacerbations of eye disease associated with recurrence of hyperthyroidism; i i) hypothyroidism, which follows thyroid tissue ablation, should be regarded as a therapeutic end point rather than as an undesirable result; iii) ablation of thyroid tissue may result in the removal of both the thyroid-orbit cross-reacting antigen(s) and the major source of thyroid-auto reactive lymphocytes. The relationship between radioiodine therapy and the course of GO is a matter of controversy, and some authors have suggested that radioiodine administration ma be associated with a worsening of preexisting ophthalmopathy. This was not observed when radioiodine treatment was associated with a 3-month oral course of prednisone. The development or progression of GO after radioiodine therapy might be due to the release of thyroid antigens following radiation injury and to subsequent exacerbations of autoimmune reactions directed towards antigens shared by the thyroid and the orbit. The view that radioiodine therapy may be associated with a progression of ophthalmopathy is not shared by some authors who claim that the apparent link between progression of

    Neonatal thyrotoxicosis is most commonly due to transplacental transfer of maternal thyroid-stimulating hormone receptor antibodies (TRAb). Bioassay of thyrotropin receptor antibodies may help to determine the risk for neonatal hyperthyroidism. Thyrotoxicosis developed in a premature infant born to a mother with Graves' disease, with a low level of TRAb by bioassay. The infant was treated with carbimazole for two months, until TRAb had disappeared. Bioassay TRAb is not always reliable for predicting the development of neonatal hyperthyroidism in infants born to mothers with Graves' disease. Thyroid function should be measured in all these neonates.

    Full Text Available The present article is a detailed study of the image of an ancient Chinese goddess, The Queen Mother of the West, called Xiwangmu 西王母 in Chinese. In the mythological tradition, Xiwangmu is a goddess who possesses the elixir of immortality and dwells in the western paradise, on the magic mountain Kunlun 崑崙. While her image can be found in mural paintings, and on lacquered objects and bronze mirrors, it appears primarily in the form of relief images on the stones and bricks of grave chambers and temples in the Han (206 BCE–220 CE grave complexes. The literary tradition reveals a multifunctional role of the mother, with her many attributes developing in accordance with the changing values of social and mythological concepts. The article concludes with a detailed discussion of her image and role within the wider cosmological context of Han grave art.

    Graves' disease is an autoimmune thyroid disorder characterized by hyperthyroidism, and patients exhibit thyroid-stimulating hormone receptor antibody. The major methods of measuring circulating thyroid-stimulating hormone receptor antibody include the thyroid-stimulating hormone-binding inhibitory immunoglobulin assays. Although the diagnostic accuracy of these assays has been improved, a minority of patients with Graves' disease test negative even on second-generation and third-generation thyroid-stimulating hormone-binding inhibitory immunoglobulins. We report a rare case of a thyroid-stimulating hormone-binding inhibitory immunoglobulin-positive patient with Graves' disease who showed rapid lowering of thyroid-stimulating hormone-binding inhibitory immunoglobulin levels following administration of the anti-thyroid drug thiamazole, but still experienced Graves' hyperthyroidism. A 45-year-old Japanese man presented with severe hyperthyroidism (serum free triiodothyronine >25.0 pg/mL; reference range 1.7 to 3.7 pg/mL) and tested weakly positive for thyroid-stimulating hormone-binding inhibitory immunoglobulins on second-generation tests (2.1 IU/L; reference range hyperthyroidism for more than 8 years, requiring 15 mg/day of thiamazole to correct. During that period, he tested negative on all first-generation, second-generation, and third-generation thyroid-stimulating hormone-binding inhibitory immunoglobulin assays, but thyroid scintigraphy revealed diffuse and increased uptake, and thyroid ultrasound and color flow Doppler imaging showed typical findings of Graves' hyperthyroidism. The possible explanations for serial changes in the thyroid-stimulating hormone-binding inhibitory immunoglobulin results in our patient include the presence of thyroid-stimulating hormone receptor antibody, which is bioactive but less reactive on thyroid-stimulating hormone-binding inhibitory immunoglobulin assays, or the effect of reduced levels of circulating thyroid

    Piezosurgery uses microvibrations to selectively cut bone, preserving the adjacent soft tissue. The present study evaluated the use of piezosurgery for bone removal in orbital decompression surgery in Graves disease via a modified pterional approach. A piezosurgical device (Piezosurgery medical) was used in 14 patients (20 orbits) with Graves disease who underwent orbital decompression surgery in additional to drills and rongeurs for bone removal of the lateral orbital wall and orbital roof. The practicability, benefits, and drawbacks of this technique in orbital decompression surgery were recorded. Piezosurgery was evaluated with respect to safety, preciseness of bone cutting, and preservation of the adjacent dura and periorbita. Preoperative and postoperative clinical outcome data were assessed. The orbital decompression surgery was successful in all 20 orbits, with good clinical outcomes and no postoperative complications. Piezosurgery proved to be a safe tool, allowing selective bone cutting with no damage to the surrounding soft tissue structures. However, there were disadvantages concerning the intraoperative handling in the narrow space and the efficiency of bone removal was limited in the orbital decompression surgery compared with drills. Piezosurgery proved to be a useful tool in bone removal for orbital decompression in Graves disease. It is safe and easy to perform, without any danger of damage to adjacent tissue because of its selective bone-cutting properties. Nonetheless, further development of the device is necessary to overcome the disadvantages in intraoperative handling and the reduced bone removal rate. Copyright © 2017 Elsevier Inc.

    Recent studies have identified common genetic variants associated with TSH, free T4 and thyroid peroxidase antibodies, but it is unclear whether these differ between patients with Hashimoto's disease and Graves' disease. To examine whether 11 common genetic variants differ between Graves' disease and Hashimoto's disease. We genotyped 11 common variants in a discovery cohort of 203 Australian patients with autoimmune thyroid disease (AITD). Two variants with significant or suggestive associations were analysed in a replication cohort of 384 Danish patients. For rs753760 (PDE10A), the minor allele frequency in Graves' disease and Hashimoto's disease was 0·38 vs. 0·23, respectively, (P = 6·42 × 10 -4 ) in the discovery cohort, 0·29 vs. 0·24 (P = 0·147) in the replication cohort and 0·32 vs. 0·24 in combined analysis (P = 0·0021; all analyses adjusted for sex). In healthy controls from Busselton, the frequency was 0·29, significantly different from Hashimoto's disease but not Graves' disease. For rs4889009 (MAF gene region), the frequency of the minor G-allele in Graves' disease and Hashimoto's disease was 0·48 vs. 0·36 (P = 0·0156) in the discovery cohort, 0·48 vs. 0·34 (P = 1·83 × 10 -4 ) in the replication cohort and 0·48 vs. 0·35 in the combined analysis (P = 7·53 × 10 -6 ); in controls, the frequency was 0·38, significantly different from Graves' disease but not Hashimoto's disease. After further adjustment for smoking, associations with rs4889009 remained significant, whereas those with rs753760 were not. Common variants in PDE10A and MAF gene regions may influence whether patients with AITD develop Graves' disease or Hashimoto's disease. © 2015 John Wiley & Sons Ltd.

    Full Text Available En este ensayo se desarrolla una reflexión acerca de la ciencia y su enseñanza. Desde las visiones epistemológicas, las interpretaciones sociológicas y complejas que conceptualizan y advierten el desarrollo y trascendencia de la ciencia hasta el examen de las ciencias naturales en el currículum de la educación secundaria, en el marco de la Reforma Integral de la Educación Básica, realizada por el gobierno mexicano en el año 2011. La reflexión sobre la ciencia contempla las diversas posturas que filósofos, s ociólogos, científicos y otros investigadores han planteado para comprender la generación y desarrollo del conocimiento. En otro momento, los planteamientos curriculares de Bernstein y el concepto de “mundo de vida” de Habermas permiten un acercamiento a l as ideas y prácticas de los docentes de educación secundaria. Aquí se vislumbra que en el desarrollo de los programas de ciencias y la cotidianidad de la escuela se encuentran obstáculos e incertidumbres que hacen difícil para los docentes transformar las concepciones simplistas de la ciencia o las prácticas rutinarias. Además, es interesante advertir que la comprensión del profesor frente a la ciencia y el currículum admite repensar los procesos de formación docente, de tal forma que los profesores cuenten con elementos que les permitan reconocer el carácter complejo del conocimiento científico y su enseñanza.

    Full Text Available Purpose : Graves' disease is the most common cause of hyperthyroidism in children and adolescents. In this study, we investigated the natural course and the prognostic factors of Graves' disease in Korean children and adolescents. Methods : One-hundred thirteen (88 girls and 25 boys patients were included in this study. A retrospective analysis was made of all patients who were diagnosed with Graves' disease. The following parameters were recorded and analyzed: patient's sex, age at diagnosis, duration of disease, laboratory findings, symptoms and signs, and family history of autoimmune thyroid disease. Results : All patients were initially treated with antithyroid drugs, either methimazole (93.8% or propylthiouracil (6.2%. Antithyroid drugs had been discontinued in 75 (66.4% of 113 patients. Of these 75 patients, 23 (20.4% relapsed after 25.5¡?#?3.7; months. Thirteen (11.5% of 23 patients, who experienced the first relapse, showed a second remission. However, 2 (1.8% of 13 patients relapsed again. Euthyroid state could not be achieved by antithyroid drugs in 1 patient, and radioactive iodine therapy was performed. The older the patient at diagnosis, the greater the likelihood of remission (P =0.034. Conclusion : Age at diagnosis seems to be a prognostic factor in Korean children and adolescents with Graves' disease, and should be taken into account in treatment plan determination.

    The aim of this study was to clarify whether Tc-99m HIG (Polyclonal Human Immunoglobulin G) can image and determine the severity of orbital involvement in patients with Graves' ophthalmopathy. Twenty-six patients between 19 and 56 years old with Graves' ophthalmopathy were examined. All patients received approximately 370 MBq Tc-99m HIG by intravenous (i.v.) injection. Planar and SPECT examination were performed 4 hours after the injection. Visual and semiquantitative evaluations were performed for both orbits by two independent observers. Clinically active ophthalmopathy patients had noticeably increased orbital accumulation of Tc-99m HIG. In patients with inactive disease, and 14 of 19 had no uptake, whereas 5 patients had orbital radioactivity accumulation. The duration of Graves' ophthalmopathy did not correlate with the presence of active ophthalmopathy and Tc-99m HIG grade. There was no correlation between clinical classification and clinical activity (r=278). There was a good correlation between clinical activity and the radioactivity grade with r=0.666 (p=0.01). The clinical classification closely correlated with Tc-99m HIG grade (r=0.423, p=0.05) Tc-99m HIG scan can clearly identified clinically active patients, and subclinical inflammation can be shown by this scintigraphic evaluation. The current preliminary results suggested that Tc-99m HIG SPECT might be useful for the assessment of disease activity in Graves' ophthalmopathy. (author)

    1 31 I therapy is safe and effective for most Graves' disease patients. It is being used more frequently in previously restricted populations such as children, adolescents, and women of childbearing age. It affords prompt, consistent relief of hyperthyroidism, but permanent hypothyroidism ensues in almost all patients. This complication is readily diagnosed with modern in vitro assays and inexpensive, life-long replacement therapy renders the patient asymptomatic and able to resume a normal lifestyle. Recent changes in NRC requirements have further liberalized the use of 1 31 I for Graves' disease in the USA, permitting more patients to be treated with effective outpatient therapy. The controversial role of 1 31 I in exacerbation of GO has been further clarified and preventive measures are available

  6. Correlation of stress with outcome of radioiodine therapy for Graves disease

    1985-06-01

    Between November 1965 and December 1983, 293 patients were treated for Graves disease using /sup 131/I. All patients were asked to identify a stressful event antedating the onset of overt clinical symptoms. Eighty-one patients were able to do this (27.6%). Two hundred forty-four patients received a single treatment, 49 required two or more treatments. Patients with stress initiating the symptoms of Graves disease became hypothyroid earlier, 50% at 12 mo compared with 36 mo for the nonstress group. At 10 yr 5% of the stress group remained euthyroid compared with 17% nonstress. The authors conclude that stress in the 12 mo or less before the onset of clinical symptoms potentiates the development of hypothyroidism induced by a standard dose of radioiodine.

    In situ observations of submarine hydrothermal activity have been conducted in Punta Banda. Baja Califronia, Mexico, approximately 400 m from the coast and at a seawater depth of 30 m. The hydrothermal activity occurs within the Agua Blanca Fault, a major transverse structure of Northern Baja California. Hot springwater samples have been collected and analyzed. Marked differences exist between the submarine hot springwater, local land hot springwaters, groundwater, and local seawater. SiO 2 , HCO 3 , Ca, K, Li, B, Ba, Rb, Fe, Mn, As, and Zn are enriched in the submarine hot springwater, while Cl, Na, So 4 2 , Mg, Cu, Ni, Cd, Cr, and perhaps Pb are depleted in relation to average and local seawater values. Very high temperatures, at the hydrothermal vents, have been recorded (102 0 C at 4-atm pressure). Visible gaseous emanations rich in CH 4 and N 2 coexist with the hydrothermal solutions. Metalliferous deposits, pyrite, have been encountered with high concentrations of Fe, S, Si, Al, Mn, Ca, and the volatile elements As, Hg, Sb, and Tl, X ray dispersive spectrometry (1500-ppm detection limit). X ray diffraction, and scanning electron microscopy of the isolated metalliferous precipitates indicate that the principal products of precipitation are pyrite and gypsum accompanied by minor amounts of amorphous material containing Si and Al. Chemical analyses and XRD of the reference control rocks of the locality (volcanics) versus the hydrothermally altered rocks indicate that high-temperature and high-pressure water-rock interactions can in part explain the water chemistry characteristics of the submarine hydrothermal waters. Their long residence time, the occurrence of an extensive marine sedimentary formation, their association with CH 4 and their similarities with connate waters of oil and gas fields suggest that another component of their genesis could be in cation exchange reactions within deeply buried sediments of marine origin

    Uncertainty about factors influencing the susceptibility and triggers for Graves' disease persists, along with a wide variation in the response to anti-thyroid drugs, currently at approximately 50% of non-responders. The aim of this narrative review is to summarize immunological concepts, with a combined endocrine and immunological perspective, to highlight potential new areas of research. Relevant studies were identified through a systematic literature search using the PubMed and EMBASE databases in March 2016. No cut-offs regarding dates were imposed. We used the terms "Graves' Disease" or "Basedow" or "thyrotoxicosis" together with the terms "etiology", "pathophysiology", "immunodeficiency", "causality", and "autoimmunity". The terms "orbitopathy", "ophthalmopathy", and "amiodarone" were excluded. Articles in English, French, German, Croatian, Spanish, and Italian were eligible for inclusion. While concepts such as the impact of iodine, smoking, human leucocyte antigen, infections, and ethnicity are established, new ideas have emerged. Pertaining evidence suggests the involvement of autoimmunity and immunodeficiency in the pathophysiology of Graves' disease. Recent studies point to specific immunological mechanisms triggering the onset of disease, which may also serve as targets for more specific therapies.

    Graves' disease, one of the commonest autoimmune disorders, has a complex genetic basis. Interleukin-17A (IL-17A) is an important cytokine involved in innate and adaptive immune responses. This case-control study sought to investigate genetic association between the IL-17A gene and the process of Graves' disease (GD). Our pilot study was performed on a cohort from Shanghai, which included 713 patients with GD and 756 healthy controls. A replicate cohort was from Xiamen, recruiting 444 patients with GD and 427 healthy subjects. Six single nucleotide polymorphisms (SNPs) (rs4711998, rs3819024, rs2275913, rs8193037, rs3819025 and rs3748067) within the IL-17A gene were genotyped by the SNPstream Genotyping Systems and Taqman PCR method. In Shanghai cohorts, the frequencies of rs8193037 alleles were strongly different between patients with Graves' disease (G, 87·6% and A, 12·4%) and healthy controls (G, 91·4% and A, 8·6%) (P = 0·00067). The A carriers were associated with increased Graves' disease risks when compared with the G carriers (OR = 1·51, 95%CI = 1·19-1·92). In replicate cohorts, the proportion of individuals carrying the A allele of rs8193037 was significantly higher in patients with Graves' disease than in controls [Graves' disease vs control, 14·3% vs 9·1%, OR = 1·66 (95% CI: 1·23-2·24), P allele  = 0·0082]. In addition, rs8193037 and rs3748067 were found to be different in both genotype and allele distributions in Graves' disease-associated ophthalmopathy patients and controls in Shanghai cohorts. Haplotype association analysis also identified five main haplotypes of those six SNPs. These results suggested that the polymorphism of IL-17A rs8193037 was strongly associated with Graves' disease susceptibility in the Chinese Han population.z. © 2015 John Wiley & Sons Ltd.

    Thyrotoxic periodic paralysis (TPP) is an uncommon complication of Graves' disease, characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. Graves' encephalopathy is an extremely rare form of encephalopathy associated with autoimmune thyroid disease (EAATD), characterized by neuropsychiatric symptoms, increased antithyroid antibodies and cerebrospinal fluid protein concentration, nonspecific electroencephalogram abnormalities, and cortico-responsiveness. Coexistence of both these complications in the same patient has not been reported before. We herein present a 48-year-old white male patient with TPP and encephalopathy as initial presentations of Graves' disease. Flaccid tetraparesis was reversed a few hours after potassium level correction and the patient did not suffer any relapse with the successful pharmaceutical management of the thyroid function. One month later, the patient presented with dizziness and behavioral symptoms, such as inappropriate laughter and anger. Brain magnetic resonance imaging revealed meningeal enhancement and cerebrospinal fluid analysis showed a mild protein increase, with a blood-brain barrier disruption. With the suspicion of EAATD, the patient was treated with high doses of corticosteroids and improved dramatically. To our knowledge this is the first reported coexistence of potentially treatable TPP and EAATD as initial neurological manifestations of Graves' disease, thereby underscoring the necessity of suspicion of possible underlying Graves' disease in patients with acute paralysis and encephalopathy of unclear origin.

    Autoimmune ophthalmopathy is one of the salient clinical features associated with Graves' disease. Exophthalmos is one of the commonest manifestations of Graves' associated ophthalmopathy. It is reported to regress after thyroidectomy favourably compared to radioiodine or antithyroid drug therapy. In this context, we present our experience based on a surgical series of Graves' disease. This is a prospective study of 15 patients of Graves' disease associated with ophthalmopathic exophthalmos. Preoperative and monthly postoperative evaluation of exophthalmos was done with Hertel's exophthalmometer, apart from documenting lid, extra-ocular muscle and orbital involvement. The minimum follow-up of the cohort was 12 months. The female to male ratio was 12:3 and the mean age of the subjects was 33.4 years (18-55). Exophthalmos was bilateral in 13 and unilateral in 2 patients. All the 15 patients underwent total thyroidectomy without any major morbidity. Exophthalmos regressed in 12 patients at a mean follow-up of 15.6 ± 6.4 months (14-38) and was static in 3. None of the cases had worsened ophthalmopathy at the final follow-up. Mean regression of exophthalmos was 2.1 mm (1-5). The regression was statistically significant at P value = 0.035. Surgery has a positive impact on the regression of ophthalmopathic exophthalmos associated with Graves' disease.

    Graves's disease is the most common cause of hyperthyroidism. There are three current therapeutic options: anti-thyroid medication, surgery, and radioactive iodine (I 131). There are few data in the literature regarding the effects of radioiodine therapy on the larynx and voice. The aim of this study was: to assess the effect of radioiodine therapy on the voice of Basedow-Graves patients. Material and method: A prospective study was done. Following the diagnosis of Grave's disease, patients underwent investigation of their voice, measurement of maximum phonatory time (/a/) and the s/z ratio, fundamental frequency analysis (Praat software), laryngoscopy and (perceptive-auditory) analysis in three different conditions: pre-treatment, 4 days, and 20 days post-radioiodine therapy. Conditions are based on the inflammatory pattern of thyroid tissue (Jones et al. 1999). Results: No statistically significant differences were found in voice characteristics in these three conditions. Conclusion: Radioiodine therapy does not affect voice quality. (author)

    Objective: To investigate the clinical curative effects of 131 I therapy combined with low-dose lithium carbonate for Graves disease. Methods: Patients with Graves disease took lithium carbonate (250 mg, once per day) orally for 5 weeks. Then they were treated with 131 I (doses=3.15 MBq(80 uCi)/g, based on 60%-70% of the thyroid size). We kept track from 6 to 24 months (averaging 14 months) and classified the results into three: cured, improved or no effect. Results: After a single cycle of 131 I therapy combined with low-dose lithium carbonate, 106 patients with Graves disease were cured, 28 were improved and 8 saw no effects, respectively 74.6%, 19.7% and 5.6% among the 142 patients. We then treated 23 of them with another 131 I therapy (without lithium carbonate). 10 of such were cured (43.5%), 8 were improved (34.8%) and the other 5 saw no effects. Among all patients, hypothyroidism was observed from 25(17.6%), 6 months after the first 131 I therapy. Conclusions: Notable curative results were observed from 131 I therapy combined with low-dose lithium carbonate for Graves disease. Moreover, the dosage of 131 I was therefore decreased, which also lowered the toxicity response. (authors)

    In the clinical management of Graves' thyrotoxicosis, one of the most important subject is when to stop antithyroid drugs after achieving an euthyroid state. T 3 suppression test and other methods have been used to forecast the outcome after drug cessation, but the results were not always satisfactory. We have attempted to predict remission of Graves' disease by single measurement of early technetium uptake without administration of triiodothyronine. Drugs were discontinued in the seventy-five patients with Graves' disease on maintenance doses of either methimazole or propylthiouracil who showed normalized uptake (4.0% or less). Of 64 patients evaluable after twelve months, 55 (86%) remained euthyroid, 8 relapsed, and 1 became hypothyoid. With its accuracy in prediction of short-term remission comparable or superior to T 3 suppression test, this rapid and simple method seemed suitable for routine use in clinical practice. (author)

    Full Text Available Osteogenesis imperfecta (OI – is a group of genetically disorders, which are charaterized by a disturbed bone formation. In turn, the excess of thyroid hormones in Graves' disease (GD also posses a negative effect on bone tissue, thereby aggravating OI. That requires from the endocrinologist the most careful management of patients with the combination of these pathologies. In this article, we present a unique clinical case of a combination of GD and OI.

    Graves' disease can be treated with antithyroid drugs (ATDs), radioiodine or surgery. Use of definitive treatments (radioiodine or surgery) varies widely across centres. Specific clinical circumstances, local facilities, patient and clinician preferences and perceptions will affect the choice of treatment. Detailed understanding of UK clinicians' views and their rationale for different treatments is lacking. To study the preferences and perceptions of UK clinicians on the role of surgery and radioiodine in the management of Graves' disease. 'British Thyroid Association' (BTA), 'Society for Endocrinology' (SFE) and 'British Association of Endocrine and Thyroid Surgeons' (BAETS) members were invited to complete an online survey examining their management decisions in Graves' disease and factors that influenced their decisions. 158 responses from UK consultants were included. The ratio of physicians to surgeons was 11:5 and males to females was 12:4. Most clinicians would commence ATDs in uncomplicated first presentation of Graves' disease. A wide range of risk estimates on the effectiveness and risks of treatment was given by clinicians. Radioiodine was used most frequently in relapsed Graves' disease. However, severe eye disease and pregnancy strongly influenced choice in favour of surgery. Surgeons underestimated the success of radioiodine (pGraves' disease. The variation appeared to be dependent on patient and disease-specific factors as well as physician experience, gender and specialty. Published by the BMJ Publishing Group Limited.

    The serum T3 to T4 ratio is a useful indicator for differentiating destruction-induced thyrotoxicosis from Graves' thyrotoxicosis. However, the usefulness of the serum free T3 (FT3) to free T4 (FT4) ratio is controversial. We therefore systematically evaluated the usefulness of this ratio, based on measurements made using two widely available commercial kits in two hospitals. Eighty-two untreated patients with thyrotoxicosis (48 patients with Graves' disease and 34 patients with painless thyroiditis) were examined in Kuma Hospital, and 218 patients (126 with Graves' disease and 92 with painless thyroiditis) and 66 normal controls were examined in Ito Hospital. The FT3 and FT4 values, as well as the FT3/FT4 ratios, were significantly higher in the patients with Graves' disease than in those with painless thyroiditis in both hospitals, but considerable overlap between the two disorders was observed. Receiver operating characteristic (ROC) curves for the FT3 and FT4 values and the FT3/FT4 ratios of patients with Graves' disease and those with painless thyroiditis seen in both hospitals were prepared, and the area under the curves (AUC), the cut-off points for discriminating Graves' disease from painless thyroiditis, the sensitivity, and the specificity were calculated. AUC and sensitivity of the FT(3)/FT(4) ratio were smaller than those of FT(3) and FT(4) in both hospitals. The patients treated at Ito hospital were then divided into 4 groups according to their FT4 levels (A: 2.3 approximately 5.4 ng/dl), and the AUC, cut-off points, sensitivity, and specificity of the FT(3)/FT(4) ratios were calculated. The AUC and sensitivity of each group increased with the FT4 levels (AUC: 57.8%, 72.1%, 91.1%, and 93.4%, respectively; sensitivity: 62.6%, 50.0%, 77.8%, and 97.0%, respectively). The means +/- SE of the FT3/FT4 ratio in the Graves' disease groups were 3.1 +/- 0.22, 3.1 +/- 0.09, 3.2 +/- 0.06, and 3.1 +/- 0.07, respectively, versus 2.9 +/- 0.1, 2.6 +/- 0.07, 2.5 +/- 0

    Full Text Available It is acknowledged that an effective path to globally protect marine ecosystems is through the establishment of eco-regional scale networks of MPAs spanning across national frontiers. In this work we aimed to plan for regionally feasible networks of MPAs that can be ecologically linked with an existing one in a transboundary context. We illustrate our exercise in the Ensenadian eco-region, a shared marine ecosystem between the south of California, United States of America (USA, and the north of Baja California, Mexico; where conservation actions differ across the border. In the USA, California recently established a network of MPAs through the Marine Life Protection Act (MLPA, while in Mexico: Baja California lacks a network of MPAs or a marine spatial planning effort to establish it. We generated four different scenarios with Marxan by integrating different ecological, social, and management considerations (habitat representation, opportunity costs, habitat condition, and enforcement costs. To do so, we characterized and collected biophysical and socio-economic information for Baja California and developed novel approaches to quantify and incorporate some of these considerations. We were able to design feasible networks of MPAs in Baja California that are ecologically linked with California's network (met between 78.5 and 84.4% of the MLPA guidelines and that would represent a low cost for fishers and aquaculture investors. We found that when multiple considerations are integrated more priority areas for conservation emerge. For our region, human distribution presents a strong gradient from north to south and resulted to be an important factor for the spatial arrangement of the priority areas. This work shows how, despite the constraints of a data-poor area, the available conservation principles, mapping, and planning tools can still be used to generate spatial conservation plans in a transboundary context.

    Objective: To discuss the change of serum TRAb and changeable regularity of thyroid function and clinical significance of pregnant women with Graves' diease treated by propylthiouracil. Methods: Detecting the serum TRAb, FT 3 , FT 4 , TSH levels of pregnant women with Graves' disease treated by propylthiouracil using radioreceptor assay and electro chemiluminescence. Results: The serum TRAb level of the pregnant women with Graves' disease in early gestation treated by propylthiouracil descended much more than that in the initial diagnosis (P<0.01). The positive rates of TRAb in the women before treated by propylthiouracil and treated 3 months, 6 months, 8 months were 90.2%, 82.9%, 68.2% and 21.9% separately. The activity of TRAb descended slightly 3 months latter after treated. The activity of TRAb descend obviously and the positive rates changed largely 8 months after treated. Conclusion: There is very important clinical significance of monitoring of serum TRAb in pregnant women with Graves' disease in diagnosis and differential diagnosis and observation of therapeutic effects. Also, a favourable prognosis judgement. Meanwhile, provides significant reference index of pathogenetic condition judgement and drug discontinuance whether or not for the clinician. (authors)

  11. A review of treatment options for Graves' disease: why total thyroidectomy is a viable option in selected patients.

    Graves' disease is the most common cause of hyperthyroidism. If left untreated, patients may have multiple systemic complications such as cardiac, reproductive, and skeletal disease. Thionamides, such as methimazole and propylthiouracil, and I(131) iodine ablation are the most commonly prescribed treatment for Graves' disease. Total thyroidectomy is often overlooked for treatment and is usually only offered if the other options have failed. In our case, we discuss a patient who was admitted to our medical center with symptomatic hyperthyroidism secondary to long-standing Graves' disease. She had a history of non-compliance with medications and medical clinic follow-up. The risks and benefits of total thyroidectomy were explained and she consented to surgery. A few months after the procedure, she was biochemically and clinically euthyroid on levothyroxine. She had no further emergency room visits or admissions for uncontrolled thyroid disease. Here we review the advantages and disadvantages of the more typically prescribed treatments, thionamides and I(131)iodine ablation. We also review the importance of shared decision making and the benefits of total thyroidectomy for the management of Graves' disease. Given the improvement in surgical techniques over the past decade and a significant reduction of complications, we suggest total thyroidectomy be recommended more often for patients with Graves' disease.

    Graves' disease is an autoimmune disease, which can manifest with a variety of extrathyroidal clinical syndromes like ophthalmopathy, pretibial myxedema (dermopathy), acropathy, cardiomyopathy, and encephalopathy. Though quite rare, this disease can also manifest with gastrointestinal symptoms such as dysphagia, heartburn, nausea, vomiting and diarrhea. We report a clinical case of Graves' disease manifesting with dysfunction of the esophagus and heartburn in a 61-year-old man. In the muscular layer of the esophagus we found dystrophic changes led to its atony, which was documented by endoscopy and high-resolution manometry. The pathology features of esophageal symptoms were: focal proliferation of the basal cells, vascular distension, and dystrophy of the epithelial cells. Antithyroid treatment led to decrease of all clinical symptoms after 5 d of Thiamazole administration. Complete restoration of peristalsis in the esophagus, according to manometry, was observed in 1 mo after initiation of treatment.

    This editorial briefly reviews studies which might answer the question as to whether radioiodine treatment causes the ophthalmopathy of Graves' disease. However, the data do not allow any conclusion one way or the other. Other possible causal factors are discussed. Further studies are required to define whether treatment of hyperthyroidism aggravates the ophthalmopathy and whether one thereby is worse than the others and by how much. (UK)

    To evaluate the relationship between eye changes and autoantibody to the thyrotropin receptor in patients with Graves' disease, the authors evaluated the eye changes using magnetic resonance imaging and the results were correlated with thyroid-stimulating antibody, thyrotropin binding inhibitor immunoglobulin and thyroid growth activity. Subjects were 15 patients with Graves' disease who had Graves' ophthalmopathy, including exophthalmos and other signs and symptoms, and 9 patients without ophthalmopathy; all were maintained in a euthyroid state by antithyroid drugs. The thyrotropin-binding inhibitor imunoglobulin was measured by a kit, and thyroid-stimulating antibody and thyroid growth activity were evaluated by cyclic adenosine 3', 5'-monophosphate production and [ 3 H]thymidine incorporation, respectively, by cultured functional rat thyroid lined cells. The sum of the swelling ratios of the four extraocular muscles correlated well with the degree of exophthalmos. The thyrotropin-binding inhibitor immunoglobulin was positive in 9 out of 15 patients with ophthalmopathy; however, no correlation was observed between the activity and exophthalmos or muscle swelling. No significant correlation was observed between muscle changes and thyroid growth activity either. On the other hand, thyroid-stimulating antibody in Graves' patients with ophthalmopathy was significantly higher than that in patients without ophthalmopathy. Moreover, the level of the stimulating activity in Graves' patients with ophthalmopathy showed a significant positive correlation with the sum of the swelling ratios of the individual eight eye muscles. These results suggest that thyroid-stimulating antibody has a close relation to Graves' ophthalmopathy. 23 refs., 4 figs

  19. Histologic Findings and Cytological Alterations in Thyroid Nodules After Radioactive Iodine Treatment for Graves' Disease: A Diagnostic Dilemma.

    Unlike the well-documented relation between radiation to the neck and development of papillary thyroid carcinoma, a causal association between radioactive iodine treatment for Graves' disease and development of thyroid malignancy is less defined. However, patients with a background of thyroid dysfunction presenting with clinically palpable thyroid nodules are followed more closely than the average population, and fine needle aspiration is recommended in such circumstances. Cytological examination of aspirates, and histologic examination of tissue provided from patients with a known history of Graves' disease, managed by radioactive iodine therapy can create a diagnostic dilemma, as the distinction between radiation effect and a malignant primary thyroid neoplasm can be very challenging. Thus, pathologists should be aware of the existence of these changes in the setting of radiation therapy for Graves' disease. Providing pathologists with appropriate clinical history of Graves' disease treated with radioactive iodine is of paramount importance in order to prevent an overdiagnosis of malignancy.

    Purpose: The aim of this study is to evaluate the response of Graves' orbitopathy to irradiation, and to specify the prognostic factors allowing one to better define the indications of orbital radiotherapy. Methods and Materials: From 1977 to 1996, 199 patients received bilateral orbital irradiation delivering 20 Gy in 10 fractions and 2 weeks for a progressive Graves' orbitopathy. 195 patients were seen between 1 and 6 months after radiotherapy. The different symptoms were studied and their response to radiation was analyzed. Factors such as age, sex, evolution of thyroid disease, history of symptoms, and previous or combined treatments were analyzed. Results: The results revealed that 50 patients (26%) had a good or excellent response, 98 (50%) had a partial response, 37 (19%) were stable, 10 (5%) had a progression of disease. The signs that best responded to radiotherapy were the infiltration of soft tissues and the corneal involvement. Responses of proptosis or oculomotor disorders were more complete when these signs were not advanced at the time of treatment. Irradiation seemed to have the same efficacy when applied as first-line treatment or after failure of corticosteroids. Neither modality of treatment of hyperthyroidism nor thyroid status at the time of orbital irradiation modified the results. The best results were recorded for early or moderately advanced presentation (p = 0.05). Patients treated within a delay of 7 months after the beginning of the ophthalmopathy had better responses than patients treated later (p = 0.10). Conclusion: Radiation therapy was successful in Graves' orbitopathy by stopping the progression of disease in almost all cases, by improving the comfort of patients, by obtaining objective responses, and by avoiding surgical treatments particularly when signs were moderate
