    Deslizamientos, flujos de escombrera y desastres geológicos similares provenientes de volcanes ocurren alrededor del mundo. Cada año estos desastres causan billones de dólares en pérdidas y un sinnúmero de fatalidades y heridos. El primer paso para reducir los efectos dañinos causados por estos desastres es el conocimiento y educación acerca de ellos. El Servicio Geológico de los Estados Unidos se dedica a educar una gran cantidad de personas a través de información e investigaciones acerca de peligros geológicos.

    Full Text Available Considerando la crisis de la investigación social, el propósito del estudio fue configurar un fundamento paradigmático para la investigación en ciencias sociales. Partiendo de dos cuerpos teóricos: Mardones, (1991; y Padrón, (1994, 1998, por medio de la deducción y del análisis se obtuvieron cuatro paradigmas de investigación que, integrados, permitieron obtener un quinto paradigma. Así, como resultado del estudio se presentan cinco paradigmas posibles para abordar la realidad: el empírico- inductivo; el racionalista deductivo; el fenomenológico vivencial, el reflexivo crítico y el holístico o de la complejidad. A lo largo del estudio, cada uno de ellos se analiza en cuatro aspectos paradigmáticos: el Ontológico, el Epistemológico, el Axiológico y el Metodológico.

    Graves' ophthalmopathy (GO) is a chronic autoimmune process that affects the retrobulbar tissue and has strong etiological links with graves' disease. Pathogenesis is incompletely understood. Symptoms include proptosis, extraocular muscle dysfunction, eyelid swelling and retraction. In its severe expression, it is a disfiguring and potentially sight threatening disease that profoundly influences and impairs the quality of life of affected individuals. Only a minority of patients develop severe expressions of the disease, requiring aggressive treatments. Glucocorticoids, orbital radiotherapy and decompressive orbital surgery represent a mainstay and a well established treatment for severe and active GO.

    Graves' orbitopathy (GO) is the main extrathyroidal manifestation of Graves' disease and the full clinical picture can impair the quality of life of the patients considerably. Active inflammation can often be effectively treated by intravenous steroids/immunosuppression, however does not lead to full remission, since inflammation rather quickly results in irreversible fibrosis and increase of orbital fat. Very important is the control of risk factors (smoking cessation, good control of thyroid function, selenium supplementation) to prevent progression to severe stages. Treatment should rely on a thorough assessment of activity and severity of GO. Rehabilitative surgery (orbital decompression, squint surgery, eyelid surgery) is needed in many patients to restore function and appearance. Anti-thyroid-stimulating hormone (TSH) receptor antibodies do specifically occur in these patients and correlate to the course of thyroid and eye disease. The levels of these antibodies can be used for treatment decisions at certain time points of the disease.

    Full Text Available Graves' ophthalmopathy constitutes a major therapeutic challenge, so specialists of various disci-plines have to combine their forces. According to the last consensus of EUGOGO (European Group On Graves' Orbitopathy the treatment of choice for Graves' ophthalmopathy is pulses of glucocorticoid (GC. Evidence for the superiority of any of the different intravenous (iv glucocorticoid schedules is lacking. Objective: to evaluate the efficacy of two different methylprednisolone pulse therapy schedules in Graves' ophthalmopathy. Materials and Methods: 30 Graves' patients with Graves' ophthalmopathy were subcategorized into two groups: Group A subjects (n = 14 were given iv glucocorticoid daily for 5 days (total 5 g and Group B patients (n = 16 were given iv glucocorticoid weekly for 5 weeks (total 5 g. All patients were examined by the ophthalmologist before and in 1 and 12 weeks after the treatment. Results: We found that in group A visual acuity was significantly higher than in group B at 12 weeks. By 12 week proptosis, diplopia had improved as well as CAS had fallen in two groups but there were no significant differences between the two groups. Conclusion: Both schedules are effective on proptosis, soft tissue swelling. Daily pulse therapy appeared to be more effective on visual acuity. Thereby in case of active Graves' ophthalmopathy associated with impairment of visual acuity, daily pulse therapy is a treatment of choice. But, in spite of improvement, strabismus, diplopia, proptosis have a marked negative effect on quality of life, disturb a lifestyle. In these cases surgery should be considered. After end of our research two patients (3 orbits had bone decompression with a good result. We consider that eye muscle surgery is next needed to restore their binocular vision.

    Graves' orbitopathy (GO), also known as thyroid eye disease is an inflammatory disease of the orbital tissue of the eye that arises as a consequence of autoimmune thyroid disease. The central feature of the disease is the production of antibodies to the thyrotropin hormone receptor (TSHR) that modulate the function of the receptor leading to autoimmune hyperthyroidism and GO. Over the years, all viable preclinical models of Graves' disease have been incomplete and singularly failed to progress in the treatment of orbital complications. A new mouse model of GO based upon immunogenic presentation of human TSHR A-subunit plasmid by close field electroporation is shown to lead to induction of prolonged functional antibodies to TSHR resulting in chronic disease with subsequent progression to GO. The stable preclinical GO model exhibited pathologies reminiscent of human disease characterized by orbital remodeling by inflammation and adipogenesis. Inflammatory lesions characterized by CD3+ T cells and macrophages were localized in the orbital muscle tissue. This was accompanied by extensive adipogenesis of orbital fat in some immune animals. Surprisingly, other signs of orbital involvement were reminiscent of eyelid inflammation involving chemosis, with dilated and congested orbital blood vessels. More recently, the model is replicated in the author's independent laboratories. The pre-clinical model will provide the basis to study the pathogenic and regulatory roles of immune T and B cells and their subpopulations to understand the initiation, pathophysiology, and progression of GO.

    Advances in the past few years have helped clinicians understand some of the pathogenetic mechanisms of Graves orbitopathy (GO), particularly the role of receptors for TSH and insulin-like growth factor I in the orbit. Optimal treatment strategies have been formulated and published by the European Group on Graves' Orbitopathy, which are hoped to improve the management of patients with this condition. The administration of intravenous pulses of steroids has been established as a superior treatment approach compared with other steroid regimens. In addition, orbital radiotherapy was effective in a subgroup of patients with GO who had eye dysmotility. The use of immunotherapies for the treatment of GO is currently being explored; of these, rituximab has emerged as a promising new agent.

La transformación de los espacios costeros al ser ocupados por el turismo, es uno de los graves problemas que no se tienen en cuenta a la hora de planificar la actividad. Cancún es un modelo paradigmático en el cual un crecimiento explosivo de turistas, habitantes y construcciones turísticas ha llevado a la masiva ocupación de un espacio costero afectado histórica y actualmente por tormentas tropicales y huracanes. De ello resulta un claro aumento de la exposición al riesgo y de la vulnerabilidad. Esta colonización espacial por el turismo y los impactos de los huracanes tienen repercusiones directas sobre los establecimientos hoteleros y las urbanizaciones turísticas que ponen en entredicho el mantenimiento de la actividad turística en un futuro.

    Full Text Available The paper aims to demonstrate that some points in the explicationof the figurative expression digging one’s own grave via the concept of blending given by Gilles Fauconnier and Mark Turner are problematic: (1 Not understanding the consequences of one’s deeds is an almost universal presuppositionof and impulse or motivation for actualizing any utterance with a forewarning or gloating content (e.g., proverbs, not the singularity characterizing just the expression of grave-digging as such. (2 The inversion of causal and temporal structure is not the case because of metonymic association between the concepts of the grave and death, as a result of which specific causal and temporal order loses any significance. Many synonymous examples can be given in which the image refers to events before the death, between the death and funeral, as well as those after burial. (3 The source domain needs not to be restricted to natural death and modern civilized funerals but should include also the cases of violent deaths, e.g., the scenario of execution and the scenario of hunting and trapping. Preliminarily, a very brief synopsis of the main phases of development of cognitive linguistic theory of metaphor and some favourite examples of blends, used also in previous works, is provided.

    Graves' ophthalmopathy (GO) is the most frequent extrathyroidal manifestation of Graves' disease, an autoimmune disorder of the thyroid, whereas the precise pathogenesis still remains unclear. In Hashimoto's thyroiditis the occurrence of proptosis is an extremely rare event. The therapy for middle and severe courses of GO shows in partly disappointing results, although several therapy modalities are possible (glucocorticoid therapy, radiotherapy, antithyroid drug treatment, surgery). All these therapies lead in only 40 - 70 % to an improvement of the pathogenic symptoms. An intensive interdisciplinary cooperation is necessary to satisfy the requirements for the treatment of Graves' ophthalmopathy. As a consequence of the very different results of the few of clinical studies that were accomplished with reference to this topic, treatment by radiotherapy in the management of the disease is presently controversially discussed. In the German-speaking countries the radiotherapy is, however, firmly established as a therapy option in the treatment of the moderate disease classes (class 2-5 according to NO SPECS), especially if diplopia is present. This article describes the sequences, dosages and fractionation schemes as well as the risks and side effects of the radiotherapy. Altogether, radiotherapy is assessed as an effective and sure method. The administration of glucocorticoids can take place before the beginning of or during the radiotherapy. For the success of treatment the correct selection of patients who may possibly profit from a radiotherapy is absolutely essential. By realising that GO proceeds normally over a period of 2-5 years, which is followed by a period of fibrotic alteration, the application of the radiotherapy in the early, active phase is indispensable. A precise explanation for the effects of radiotherapy in treatment of the GO does not exist at present. The determination of the most effective irradiation doses was made from retrospectively evaluated

    Thyroid orbitopathy is a relatively rare disease. Prevalence data are lacking and can only be estimated. The incidence of thyroid orbitopathy has been documented in one American study (16 cases per 100,000 population per year for females and 2.9 cases per 100,000 population for males). Thyroid orbitopathy can affect every race and age group. The majority of patients present in middle age with concurrent thyrotoxicosis due to Graves' disease. The onset of orbitopathy usually coincides with the hyperthyroidism, though the two may be asynchronous by months or sometimes years. A small proportion of patients with thyroid orbitopathy have primary hypothyroidism or are euthyroid. Female patients outnumber males by 2-5 to 1. Smoking increases the risk of thyroid orbitopathy up to 8-fold.

    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.

Design: A prospective, controlled, University Hospital based study Subjects and Methods: The current study comprised 60 patients diagnosed with GO at Mansoura Ophthalmic Center. Thirty five patients of them with moderate to severe GO formed the study group and twenty five patients with negligible to very mild GO formed the control group in the euthyroid state. The study group was further subdivided based on their predominant clinical signs into a proptosis subgroup and a muscle restriction subgroup . Psychiatric changes were assessed with the Middlesex Hospital Questionnaire (MHQ. Biochemical analyses included serum-free thyroxine and thyroid-stimulating hormone (TSH concentrations, TSH receptor antibody (TRAb activity and anti-thyroglobulin particle agglutination (TGPA and antithyroid microsomal particle agglutination (MCPA. Results: The proptosis group reported significantly higher scores on anxiety, depression, and phobia than the muscle restriction group (P< 0.0001. The proptosis and muscle restriction subgroups reported significantly higher scores on all subscales compared to the control group (P < 0.05. The scale scores of depression and phobia showed a positive correlation with scores of anxiety (P< 0.0001. The serum TRAb activity showed a significant correlation with anxiety, phobia and hysteria (P < 0.0001. Conclusion: The psychiatric aspect of GO should be evaluated during routine follow-up and should be considered when making management decisions. Thyroid specific antibodies may be useful in confirming the diagnosis of GO.

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.

    Graves' ophthalmopathy is a complex orbital condition with a controversial pathogenesis. It is the clinical expression of a discordance between the inextensible orbit and hypertrophic muscular and fatty elements within the orbit responding to immunological stimulation. The relationship between the orbital and its content can be improved by surgical expansion which increases the useful volume of the orbit. This procedure can be combined with lipectomy to decrease the volume of the orbital contents. We briefly recall the history of surgical decompression techniques and present our experience with Graves' ophthalmopathy patients.

    Full Text Available Introduction. Graves ophthalmopathy is an autoimmune disease, which is the consequence of thyroid dysfunction. Ocular manifestations occur in 50% of patients with Graves disease. The changes occur due to the inflammatory cell infiltration of retrobulbar fat tissue and extraocular muscles. Ultrasonography of eye orbit provides important information about the condition of retrobulbar adipose tissue and the thickness of extraocular muscles. Objective. The aim of our study was to show the clinical significance of orbital ultrasonography in the diagnostics and follow-up of patients with Graves disease. Methods. The authors examined 154 patients with Graves ophthalmopathy at the Clinic of Ophthalmology of the Clinical Centre in Kragujevac during the period 2008–2010. Ophthalmological examination included visual acuity testing (Snellen chart, biomicroscopy and applanation tonometry, direct and indirect ophthalmoscopy, dry eye testing and exophthalmometry (Hertel. Orbital ultrasonography examination and extraorbital muscle measurement was done by ultrasound B-scan. Results. The disease was more frequent in women (79.87% aged from 36–45 years. Most patients had hyperthyreoidism (54.55%. In relation to the duration of the disease, the most frequent clinical signs were bilateral ptosis, conjunctival chemosis and periorbital edema. According to our data the highest number of patients had enlarged medial straight muscle. Conclusion. Graves ophthalmopathy is the most frequent sign of thyroid disease. By orbital ultrasonography we detected extended echogram and measured the thickness of the extraocular muscle. Computerized tomography and magnetic resonance scan were utilized for cases of insufficiently manifested clinical signs of the disease. The advantages of ultrasonography lie in easy handling, patients’ comfort, short time of examination and possibilities of repetition.

    Una sociedad que en camino de su progreso (técnico) se genere a sí misma múltiples peligros debe, en compensación, desarrollar los instrumentos de control social que le procuren seguridad. A tal efecto se recurre, también, cada vez más al Derecho penal, el cual, sin embargo, no puede ejecutar esa tarea sin acortar o incluso renunciar a elementos esenciales del más básico Estado liberal de derecho.

  16. Mass Graves, Landscapes of Terror

    Ferrándiz, Francisco

    2009-06-01

    Full Text Available The recent exhumation of mass graves from the Spanish Civil War and the Post-War years, mostly involving the largely abandoned graves of the Francoist rearguard, have become a central element in contemporary debates about the conflict and the regime following it. In this paper, the complexity and dynamism of this process is analysed, including from political and legal initiatives of great social and media impact to local actions on the ground, at times failed, ephemeral or almost imperceptible, but no less crucial. From the point of view of many of the people involved in the pro-exhumation associations, opening up the graves is part of a basic exercise in justice and ‘dignification’, showing the scope and systematic nature of repression while reverting the ‘infrahuman’ disposition of the executed corpses, a feeling crystallised in the common expression ‘thrown’ or ‘buried like dogs’, used very often to justify the need of carrying out exhumations. Politics of dignification and ‘rehumanization’ of these ‘incorrectly’ buried bodies are incorporating, in the last few months, elements drawn from international law, such as the concept of ‘crimes against humanity’.

    Las exhumaciones de fosas comunes de la Guerra Civil española y la posguerra de la última década, muy especialmente de fosas abandonadas de la retaguardia franquista, se han colocado en un lugar central de los debates contemporáneos sobre la naturaleza y alcance de la contienda y el régimen que surgió de ella. En este artículo, se analiza la complejidad y dinamismo del proceso, que incluye desde iniciativas políticas y judiciales de enorme proyección pública y mediática, como la Ley de la Memoria o el controvertido auto de Garzón sobre los crímenes del franquismo, hasta acciones locales a veces fallidas, imperceptibles o efímeras, pero no menos cruciales. Desde el punto de vista de muchos de los actores sociales implicados en las exhumaciones

    Graves' orbitopathy is the extrathyroidal manifestation of Graves' disease, which is the most common cause of exophthalmos. As eye symptoms usually coincide with the development of thyrotoxicosis, the diagnosis of the disease is rarely difficult. The aim of the authors was to summarize the differential diagnosis of Graves' orbitopathy based on literature review and presentation of their own four problematic cases on this topic. They conclude that symptoms similar to endocrine orbitopathy are present in other disorders. Endocrinologists need to be aware of these other conditions to avoid treatment failures.

    Full Text Available En el estado de Baja California Sur existen solo cuatro oasis con extensiones mayores a 2.0 km 2 ; La Purísima (2.25 km 2 representa el tercero en extensión. En el pasado el oasis fue frecuentemente afectado por inundaciones resultantes de los eventos extremos de precipitación, que generaron graves daños en la cuenca. Se realizó un diagnóstico del oasis La Purísima, con respecto a posibles inundaciones como consecuencia de lluvias extremas, lo cual incluye el análisis estadístico de la precipitación para la elaboración de un modelo hidrológico e hidráulico, con el fin de calcular el caudal máximo, el volumen y la frecuencia de crecidas en los cursos del arroyo Cadegomo bajo diferentes escenarios de lluvias extremas. Finalmente se elaboró un mapa de peligro por inundación según los escenarios elaborados Se efectuó un análisis de la ocurrencia de inundaciones en el pasado y sus efectos en el oasis por medio de evidencias históricas de inundación de la zona, para verificar su posible aplicación en la calibración de los modelos. Los caudales resultantes de los eventos de precipitación extremos generan un incremento importante de los niveles en el drenaje de la cuenca. La respuesta del arroyo es un incremento en el área de inundación de hasta 14% respecto al tiempo de retorno de 20 años. Un evento de 1 000 años generaría un incremento en el área de inundación de 67% y bajas, afectando las zonas de la región urbana, así como todos los lotes de cultivo

    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.

    Full Text Available Los aluviones repentinos representan uno de los principales peligros geológicos que afectan el departamento Pocito. Las aguas de lluvias torrenciales ocurridas durante los meses de verano, pueden dar lugar, en sólo algunas horas, a violentos aluviones caracterizados por su alta velocidad, poca profundidad, gran carga de sedimentos y detritos. El fenómeno se agrava cuando se reduce el índice de infiltración debido a lluvias previas. Estos torrentes se generan en la zona montañosa, con fuerte pendiente. La extensión del área de las unidades activas en el piedemonte de la sierra de Zonda se determinó a través del estudio de fotografías aéreas y de mapas con la topografía de la zona. Las áreas activas se ubicaron topográficamente por debajo de las unidades más antiguas del piedemonte. En la planicie aluvial pedemontana, donde se encuentra la zona urbana y rural, los aluviones se han restringido a las calles 13 y 15, orientadas paralelas a la dirección de flujo. Durante las lluvias torrenciales, estas calles se convierten en verdaderos cauce fluviales, mientras que en las calles orientadas perpendicularmente a las anteriores, los daños son mayores.En este trabajo se realiza la evaluación de los aspectos hidrológicos de una cuenca de régimen torrencial, como es la del arroyo La Lechuza, causante de la mayoría de los daños en el departamento. Los efectos de estos eventos pueden ser minimizados a través del establecimiento de un sistema de predicción y alerta, de la educación pública y toma de medidas estructurales.

    Menconi, Francesca; Marcocci, Claudio; Marinò, Michele

    2014-01-01

    Graves' disease (GD) is an autoimmune disorder involving the thyroid gland, typically characterized by the presence of circulating autoantibodies that bind to and stimulate the thyroid hormone receptor (TSHR), resulting in hyperthyroidism and goiter. Organs other than the thyroid can also be affected, leading to the extrathyroidal manifestations of GD, namely Graves' ophthalmopathy, which is observed in ~50% of patients, and Graves' dermopathy and acropachy, which are quite rare. Presumably, the extrathyroidal manifestations of GD are due to autoimmunity against antigens common to the thyroid and other affected organs. Although its exact etiology remains to be completely understood, GD is believed to result from a complex interaction between genetic susceptibility and environmental factors. Clinically, GD is characterized by the manifestations of thyrotoxicosis as well as by its extrathyroidal features when present, the latter making the diagnosis almost unmistakable. In the absence of ophthalmopathy, the diagnosis is generally based on the association of hyperthyroidism and usually diffuse goiter confirmed with serum anti-TSHR autoantibodies (TRAbs). Hyperthyroidism is generally treated with anti-thyroid drugs, but a common long term treatment strategy in patients relapsing after a course of anti-thyroid drugs (60-70%), implies the use of radioactive iodine or surgery.

    Graves' disease (GD) is a systemic autoimmune disease that is characterized by hyperthyroidism, orbitopathy and in rare cases dermopathy. Graves' orbitopathy (GO) is an inflammatory disease of eye and orbit which occurs in about 30-60% of patients. Hyperthyroidism occurs due to the presence of stimulating TSHR-autoantibodies (TRAbs) leading to increased serum levels of thyroid hormones. Attempts to induce Graves' disease in mice by immunization against the hTSHR or its variants have resulted in production of TRAbs that stimulate thyroid follicular cells to increase thyroid hormone secretion. Graves' like orbital changes, such as inflammation, adipogenesis and muscle fibrosis are more difficult to induce. In this review we summarize different methods used to induce murine Graves'-like disease and their impact on murine orbits.

    To report the results of radiotherapy for patients with failure, adverse reactions or relative contraindications to the use of steroids or immunosuppressants, by using newly developed quantitative indexes. Fourteen female and six male patients with Graves` ophthalmopathy were treated with radiotherapy between 1989 and 1996. Prior to radiotherapy, eight patients received treatment with prednisone, four received immunosuppressants and four received a combination of both. Four patients with contraindications to steroids were initially managed with radiotherapy. Most of the patients received a dose of 24-28 Gy in 2 Gy fractions. We used the newly developed motility limitation index to assess extraocular motility. Treatment was well tolerated. There have been no late complications. All 12 patients with soft tissue signs such as edema, irritation, tearing and pain were improved. Proptosis did not improve or improved only slightly, 3 mm at best. However, proptosis in all but two has been stabilized and has not deteriorated in the follow-up period. Most of the patients have experienced an improvement of eye-muscle motility. Extraocular muscles that work for elevation were impaired more severely than the other muscles and this tended to remain. Of the 16 patients using steroids before or when radiotherapy was initiated, 15 were tapered off and only one patient required additional steroids, thus sparing the majority from steroid adverse reactions. Radiotherapy was effective in preventing exacerbations of active inflammatory ophthalmopathy in patients with Graves` disease with minimal morbidity and thus eliminated the adverse reactions associated with protracted corticosteroid use. The newly developed motility limitation index was useful in detecting delicate changes in motility of individual extraocular muscles. (author)

  2. Graves' Disease that Developed Shortly after Surgery for Thyroid Cancer

    2013-09-01

    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.

    Full Text Available Costa Rica ha incrementado el uso de plaguicidas de mayor toxicidad, debido entre otras cosas al desarrollo de plagas más resistentes y la necesidad que tienen algunos productos agrícolas de exportación de mantener su posición en el mercado internacional. El ser humano al entrar en contacto con los plaguicidas puede experimentar efectos adversos en su salud desde agudos hasta crónicos que se manifiestan en diferentes grados. Para generar indicadores de peligro en salud en algunos cultivos por el uso de estas sustancias, se utilizaron la cantidad de plaguicidas aplicada y su toxicidad. Los datos de uso se recopilan directamente de los productores, a través de un cuestionario, los ingredientes activos identificados se caracterizaron por su toxicidad y se clasificaron por la manifestación de los efectos. Se calculó como indicador la cantidad de plaguicidas aplicada (kg ia/ha/año por las clases de toxicidad consideradas más peligrosas: 1. Efectos de toxicidad aguda en grado de alto a extremo y 2. Tres o más efectos crónicos positivos. Se recomienda vigilar el uso de bromuro de metilo, metam sodio, terbufos, etoprofos, endosulfan, MCPA y carbofuran por toxicidad aguda de alta a extrema y mancozeb, paraquat, diazinon, 2,4-D y carbofuran por efectos crónicos.  

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

    LENUS (Irish Health Repository)

    Cronin, C C

    2012-02-03

    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.

En este estudio se abordará la regulación de la prescripción de la acción disciplinaria por estas graves conductas en los Regímenes Disciplinarios aplicables a la Fuerza Pública en los últimos treinta años y en el actual Código Único Disciplinario. Para esto se tendrá en cuenta las consecuencias de orden jurídico, político, social y económico, a nivel nacional e internacional, que puede ocasionar la declaratoria de prescripción, bien sea por la ineficiencia o el desinterés por parte de los agentes estatales en adelantar los respectivos procesos disciplinarios tendientes a evitar no sólo la impunidad en materia administrativa sancionadora, por la comisión de infracciones atroces, sino también ante la necesidad de preservar el buen nombre y la buena marcha de la administración, y a su vez, cumplir con los estándares internacionales trazados sobre la materia. Finalmente se propone una reforma legal extendiendo el término de prescripción de manera razonable, para preservar los derechos de las víctimas y los disciplinados y asegurar el cumplimiento eficaz de las obligaciones del Estado colombiano, para garantizar el cumplimiento de los compromisos internacionales sobre la materia, en defensa de los derechos humanos y del derecho internacional humanitario.

  6. Orbital dissection defatting technique for Graves disease.

    1984-04-01

    Five patients with Graves disease and bilateral proptosis were treated with different incisional approaches. They all underwent orbital decompression by removal of the anterior medial orbital walls, the anterior ethmoidal sinuses, the orbital floors, and multiple incisions of the orbital periosteums . The defatting technique, which consists of applying manual anterior orbital pressure with alternate removing of small lobules of fat, was added when it was intraoperatively decided by Hertel exophthalmometer measurement that more decompression was needed. It is estimated that one-third more reduction in proptosis resulted. An average total decrease in proptosis of 9 mm per orbit occurred. Both visual accuities and visual fields returned to normal. The only important complication was the development of hypertropia in down gaze in one patient. A potential value of this technique is its use with orbital floor decompression alone. It may be possible to avoid removing the medial and lateral walls of the orbit, thereby decreasing complications. Defatting may also be a valuable addition in those rare cases where all decompression techniques available are needed to affect an adequate decompression.

    Purpose: To report a rare sign, paracentral corneal dellen that developed in a middleaged female patient with Graves ophthalmopathy.Methods:A paracentral corneal dellen developed in the left eye in a 42-year-old woman who was diagnosed as Graves ophthalmopathy. The patient had remarkable upper eyelid retraction, upper eyelid lag and upward motility restriction. The Graves ophthalmopathy was classified as Grade V according to NOSPECS classification.Results:Local artificial tear film and 0.3% Tobramycin eye drops were administered to both eyes.Twenty-four hours later, the left corneal dellen disappeared.Conclusions:Graves ophthalmopathy can lead to paracentral corneal dellen because of severe upper eyelid retraction and upward motility restriction of the eye in spite of the lack of lagophthalmos. Artificial tear drop and antibiotic eye drop therapy helped even though the patient did not have corneal exposure.

    Autoimmune thyroid disease is the most common organ-specific autoimmune disorder which consists of two opposing clinical syndromes, Hashimoto's thyroiditis and Graves' (hyperthyroidism) disease. Graves' disease is characterized by goiter, hyperthyroidism, and the orbital complication known as Graves' orbitopathy (GO), or thyroid eye disease. The hyperthyroidism in Graves' disease is caused by stimulation of function of thyrotropin hormone receptor (TSHR), resulting from the production of agonist antibodies to the receptor. A variety of induced mouse models of Graves' disease have been developed over the past two decades, with some reproducible models leading to high disease incidence of autoimmune hyperthyroidism. However, none of the models show any signs of the orbital manifestation of GO. We have recently developed an experimental mouse model of GO induced by immunization of the plasmid encoded ligand binding domain of human TSHR cDNA by close field electroporation that recapitulates the orbital pathology in GO. As in human GO patients, immune mice with hyperthyroid or hypothyroid disease induced by anti-TSHR antibodies exhibited orbital pathology and chemosis, characterized by inflammation of orbital muscles and extensive adipogenesis leading to expansion of the orbital retrobulbar space. Magnetic resonance imaging of the head region in immune mice showed a significant expansion of the orbital space, concurrent with proptosis. This review discusses the different strategies for developing mouse models in Graves' disease, with a particular focus on GO. Furthermore, it outlines how this new model will facilitate molecular investigations into pathophysiology of the orbital disease and evaluation of new therapeutic interventions.

    To evaluate the association of HLA types with Turkish patients with Graves' disease, HLA typing, clinical findings, and thyroid antibodies were correlated. The HLA types, clinical findings (ophthalmopathy and age at onset), and thyroid stimulating hormone (TSH) receptor (TRAb) and antithyroid microsomal antibodies (MAb) were analyzed. Seventy Turkish patients with Graves' disease and 306 control subjects were assessed. Serological HLA typing was performed in HLA A, B, C, DR, and DQ loci. There was a significantly increased prevalence of HLA B8, B49, DR3, DR4, and DR10 in Graves' disease. The association of Graves' disease with HLA DR3 was found to be less strong than previously described. The HLA DR4 antigen may contribute to the predisposition of Graves' disease in Turkey. The results suggest that HLA B7, B13, DR7, DQw2, and DQw3 may confer a protective effect for Graves' disease in Turkey. Patients carrying HLA B12, B18, and B44 haplotypes had a tendency to develop the disease at a later age. The difference from the other studies may be the result of the selection of the controls; in part, of the variability in serological typing reagents; and, also, of the rather weak HLA associations with the disease.

    Graves disease is a common diffuse abnormality of the thyroid gland usually characterized by thyrotoxicosis. We performed color-flow Doppler sonography in 16 patients with Graves disease and compared the results with those in 15 normal volunteers and 14 patients with other thyroid diseases (eight with multinodular goiter, four with focal masses, and two with papillary thyroid carcinoma). All 16 Graves disease patients exhibited a pulsatile pattern we call "thyroid inferno." This pattern consists of multiple small areas of intrathyroidal flow seen diffusely throughout the gland in both systole and diastole. In systole, both high-velocity flow (color coded white) and lower velocity flow (color coded red and blue) were noted. In diastole, fewer areas of flow and lower velocity flow were noted. Patients with Graves disease also exhibited color flow around the periphery of the gland. The inferno pattern did not occur in normal subjects or in patients with other thyroid diseases. On occasion, focal areas of intrathyroidal flow were detected in patients with multinodular goiter and focal thyroid masses. High-resolution gray-scale images did not show the small vascular channels from which the flow signal originated. Color-flow Doppler sonography shows promise as a cost-effective, noninvasive technique for diagnosing Graves disease.

    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)

    2014-11-01

    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 OBJECTIVES: To estimate oculometric parameters of Graves' ophthalmopathy in comparison to healthy eyes using digital photography and digital image analysis. INTRODUCTION: Graves' ophthalmopathy is the main cause of eye proptosis. Because these protrusions cause clinically perceived distortions in orbital architecture, digital photographs can be used to detect and quantify these changes. METHODS: We carried out a cross-sectional study comprising 12 healthy volunteers and 15 Graves' ophthalmopathy patients with the purpose of evaluating the use of simple, non-invasive digital photography to estimate oculometric parameters of Graves' ophthalmopathy and compare them with the parameters of unaffected eyes. Facial photographs of cases and controls were taken in a standardized manner. Oculometric parameters were compared between the groups and then correlated to proptometer measures. RESULTS: All estimated oculometric variables showed significant differences between the groups, in particular with regard to mediopupilar aperture, lateral height, distance from the iris edge to the lateral boundary of the palpebral fissure, and distance from the higher point of the iris to the lateral limit of the palpebral fissure. The product of medial aperture and horizontal palpebral fissure also revealed greater discrepancy between the groups. Proptometer measures showed significant linear correlation between the distance from the iris edge to the lateral boundary of the palpebral fissure and between the distance from the higher point of the iris to the lateral limit of palpebral fissure (p<0.05. CONCLUSIONS: Comparative analysis of oculometric parameters in Graves' ophthalmopathy suggests that eye proptosis is related to an asymmetric increase in lateral oculometric measures. Standardized digital photographs can be used in clinical practice to objectively estimate oculometric parameters of Graves' ophthalmopathy patients.

    Full Text Available We describe a female patient who presented with Graves disease and a neck mass. Radiological characteristics of the mass suggested thymic hyperplasia. She was treated with methimazole, and because the mass did not regress after six months of therapy, the patient had total thyroidectomy and thymectomy. Pathological examination was consistent with chronic lymphocytic thyroiditis and thymic hyperplasia. Microscopic changes in the thymus can be detected in one third of patients with Graves disease, but massive enlargement is rare. It has been reported that regression occurs in most patients after a euthyroid state has been achieved; however, in some patients, thymectomy may be indicated. Turk Jem 2009; 13: 11-2

    Peripartum cardiomyopathy (PPCM) is a rare life-threatening cardiomyopathy of unknown etiology that occurs during the peripartum period in previously healthy women. Autoimmune and viral factors have been suggested to be involved in PPCM. Here we describe a patient with Graves' disease, which is one of the organ-specific autoimmune diseases, who developed acute heart failure due to PPCM at 2 weeks after her first delivery. The patient recovered completely with conservative treatment for heart failure. An association between PPCM and Graves' disease has not been reported before. PPCM may be an organ-specific autoimmune disease, so the coexistence of other autoimmune diseases should be considered in PPCM patients.

    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.

    Full Text Available En tanto “mapa” es toda “representación gráfica que facilita el conocimiento espacial de cosas, conceptos, condiciones, procesos o eventos que conciernen al mundo humano”, el término “mapa” refiere a muchas imágenes muy diferentes, que usan diversas técnicas y soportes, apelan a lenguajes visuales muy heterogéneos, convenciones gráficas que han variado a lo largo del tiempo, etcétera. Este trabajo propone dos categorías metodológicas para abordar la pluralidad de la imagen cartográfica sin renunciar a esa definición amplia e inclusiva. La primera es la noción de género cartográfico, que permite agrupar y clasificar mapas que comparten claves temáticas, estilísticas, técnicas y/o composicionales. La segunda es la noción de serie, porque el armado de una serie crea claves de lectura y de interpretación y, consecuentemente, un mismo mapa no comunica lo mismo en dos series diferentes. Con ejemplos se discutirán las potencialidades y las limitaciones de estas propuestas metodológicas

    1982-11-01

    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 9/-9..mu..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<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.

    2015-09-01

    Although there are adequate therapies for Graves' hyperthyroidism, mild to moderate Graves' orbitopathy (GO) is usually treated symptomatically whereas definitive therapy is reserved for severe, vision-threatening GO. Importantly, none of the treatment regimens for Graves' disease used today are directed at the pathogenesis of the disease. Herein, we review some aspects of what is known about the pathogenesis of these 2 major components of Graves' disease, specifically the apparent important roles of the TSH and IGF-1 receptors, and thereafter describe future therapeutic approaches directed at these receptors. We propose that targeting these receptors will yield effective and better tolerated treatments for Graves' disease, especially for GO.

    Full Text Available A presença de hipertrigliceridemia grave durante a gravidez é rara, mas comporta grande possibilidade de desenvolver complicações, como a pancreatite aguda, que coloca em risco a mãe e o feto. Apresentamos o relato da evolução da gestação de uma paciente portadora de hipertrigliceridemia grave que havia apresentado pancreatite aguda dois meses antes da fecundação. Foi tratada durante o pré-natal com dieta e 3,0 g de ácidos graxos de cadeia ômega-3 (ácidos eicosapentaenóico 14% e docosahexaenóico 11,13%. Os níveis de triglicerídeos foram mantidos abaixo de 800 mg/dl, sendo este limite considerado seguro para evitar o desenvolvimento de pancreatite aguda. A gestação evoluiu, sem intercorrências, para parto vaginal, a termo. O recém-nato não apresentou alterações morfológicas ao nascimento. Concluímos que, nesta paciente grávida e portadora de hipertrigliceridemia grave, uma dieta adequada e o emprego de ácidos graxos de cadeia ômega-3 foram eficazes em prevenir a pancreatite aguda. Esta abordagem terapêutica pode ser uma alternativa para as gestantes portadoras de hipertrigliceridemia familiar.

El énfasis del análisis se centra en la construcción de argumentos para demostrar que el uso del diario impreso es una herramienta en el proceso de enseñar y aprender contenidos geográficos, considerándolo como generador de informaciones que pueden ser utilizadas para la construcción de conocimientos. Las informaciones disponibles en los artículos de diario necesitan de un análisis crítico, ya que no son informaciones neutras, para esto, se utilizaron dos opciones metodológicas: los padrones de manipulación de los principales medios de comunicación y la dimensión de los discursos. Esos recursos analíticos ofrecen una interpretación pautada en criterios que sirve para filtrar las informaciones utilizadas en la construcción de los conocimientos. De esta manera, enseñar y aprender contenidos geográficos con la ayuda de diarios, en una perspectiva de la Educación Geográfica, implica que el profesor contemple el poder de la información y lo fundamental que es su uso en el proceso de enseñanza-aprendizaje, basándose en criterios relacionados a principios socio ambiéntales.

  7. Clinical update: treatment of hyperthyroidism in Graves' ophthalmopathy.

    The presence of thyroid eye disease (TED) may influence the treatment of hyperthyroidism in patients with Graves' disease. Moreover, treatment of hyperthyroidism may affect the course of Graves' ophthalmopathy (GO). We review the literature and summarise recent knowledge about the impact of treatment modality for hyperthyroidism in GO. Anti-thyroid drugs (ATDs) remain the simplest and safest way to treat hyperthyroidism in patients with GO, but they are associated with a high relapse rate of hyperthyroidism and they have no effect on the course of GO. Radioactive iodine (RAI) treatment may be associated with exacerbation of GO especially in high risk patients, when glucocorticoid prophylaxis may be indicated. Large prospective trials are still lacking to define the exact effect of RAI on the course of GO, particularly in relation to other known risk factors. Likewise, clear guidelines for prophylactic glucocorticoid therapy are needed. RAI should be cautiously used in patients with more severe ophthalmopathy and concomitant I.V glucocorticoids should be considered. Thyroid surgery, whether total or subtotal thyroidectomy, has no effect on the course of ophthalmopathy. However, total thyroid ablation that combines surgery with radioactive iodine, as a means of achieving thyroid antigen disappearance, is increasingly gaining attention for the treatment of patients with GO, especially those undergoing thyroid surgery, but also for those with severe unresponsive ophthalmopathy. Studies supporting this approach are awaited.

  8. Hyperthyroidism in Graves disease. Current trends in management and diagnosis

    The radioimmunoassay for T/sub 3/ is now widely available and is a useful diagnostic tool for hyperthyroidism, especially in T/sub 3/-thyrotoxicosis. It is an essential tool in the management of hyperthyroidism that persists after treatment with normal T/sub 4/ serum levels or, in euthyroid cases, with low T/sub 4/ serum levels. In these conditions, it reflects the metabolic state more accurately than serum levels of T/sub 4/. A promising new test is the response of radioimmunoassayable TSH to protirelin relin (TRH) administration. An absent response indicates pituitary suppression and thyroid autonomy as seen in frank hyperthyroidism or euthyroid Graves disease, treated or untreated. It is safer and quicker than the conventional T/sub 3/ suppression test of thyroid radioactive iodine uptake and may replace it at least partly in the future. The recently recognized sharp decline in the remission rate of patients subjected to thyroid drug therapy in the last decade has made this treatment much less efficacious. By necessity, it will probably lead to greater reliance on treatment with radioactive iodine in the majority of the patients with the hyperthyroidism of Graves disease.

    Graves' orbitopathy (GO) is the main extrathyroidal manifestation of Graves' disease, though severe forms are rare. Management of GO is often suboptimal, largely because available treatments do not target pathogenic mechanisms of the disease. Treatment should rely on a thorough assessment of the activity and severity of GO and its impact on the patient's quality of life. Local measures (artificial tears, ointments and dark glasses) and control of risk factors for progression (smoking and thyroid dysfunction) are recommended for all patients. In mild GO, a watchful strategy is usually sufficient, but a 6-month course of selenium supplementation is effective in improving mild manifestations and preventing progression to more severe forms. High-dose glucocorticoids (GCs), preferably via the intravenous route, are the first line of treatment for moderate-to-severe and active GO. The optimal cumulative dose appears to be 4.5-5 g of methylprednisolone, but higher doses (up to 8 g) can be used for more severe forms. Shared decision-making is recommended for selecting second-line treatments, including a second course of intravenous GCs, oral GCs combined with orbital radiotherapy or cyclosporine, rituximab or watchful waiting. Rehabilitative treatment (orbital decompression surgery, squint surgery or eyelid surgery) is needed in the majority of patients when GO has been conservatively managed and inactivated by immunosuppressive treatment.

  1. Premature hair greying may predict reduced bone mineral density in Graves' disease.

    LENUS (Irish Health Repository)

    Leary, A C

    2012-02-03

    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.

    Full Text Available OBJETIVO: Descrever o padrão de distribuição das oclusopatias em adolescentes brasileiros e identificar fatores associados a esse agravo bucal. MÉTODOS: Foram analisados dados de 7.328 e 5.445 adolescentes de 12 e 15-19 anos, respectivamente, participantes da Pesquisa Nacional de Saúde Bucal (SBBrasil 2010. O desfecho foi oclusopatia muito grave segundo o índice de estética dental. As variáveis de exposição foram sexo, cor da pele, renda familiar mensal, número de bens, aglomeração no domicílio, cárie não tratada, perda dentária, uso, frequência e motivo da consulta odontológica. Foram conduzidas análises de regressão logística considerando a complexidade do desenho amostral, com base em modelo hierarquizado. RESULTADOS: Prevalência de oclusopatia muito grave foi observada em 6,5% e 9,1% nos jovens de 12 e 15-19 anos, respectivamente. Após análise ajustada, a chance do desfecho foi 1,59 (IC95% 1,08;2,34 vez maior nos pardos e pretos em relação aos brancos e 2,66 (IC95% 1,26;5,63 vezes maior dentre aqueles com perda de pelo menos um primeiro molar aos 12 anos. Jovens de 15-19 anos cuja renda familiar mensal foi de até R$ 1.500,00 (OR 2,69 [IC95% 1,62;4,47] e aqueles que consultaram o dentista para tratamento (OR 2,59 [IC95% 2,55;4,34] apresentaram maior chance de oclusopatia muito grave quando comparados aos de maior renda e que procuraram o dentista para prevenção. CONCLUSÕES: A distribuição das oclusopatias em adolescentes brasileiros segue o padrão de iniquidade social de outros agravos à saúde. Essas informações são úteis para a formulação de critérios relacionados tanto com a distribuição e provisão de recursos quanto com as prioridades de tratamento ortodôntico fundamentados no princípio da equidade da atenção à saúde bucal.

    The immune mechanism of Graves' diseases (GD) and the roles of regulator T cells were investigated. In 32 patients with GD (GD group) and 20 healthy volunteers (control group), flow cytometry was used to detect the proportion of CD4+CD25+ cells, MACS to isolate CD4+ CD25+ cells,RT-PCR to assay the expression of FOXP3, and ELISA to test the level of IL-10, respectively. It was found that there was no significant change in the proportion of CD4+CD25+ T cells between GD group and control group (P>0.05), while secretion of IL-10 and expression of FOXP3 in GD group were lower than control group (P<0.01 and P<0.05, respectively). In conclusion, though the proportion of regulatory T cells of peripheral blood lymphocytes in the patients with GD, the functions of them were significantly weakened, which might be a pathogenic factor in GD.

  5. The story of the only (? megalith grave on Gotland Island

    2010-12-01

    Full Text Available In this paper, we discuss the easternmost material expression of the Funnel Beaker Culture – a megalith grave on the west coast of Gotland Island in the Baltic Sea. The people who built and used the megalith brought the Neolithic lifestyle to Gotland. The biography of this monument includes two excavations, of which we participated in the latest in 1984. Our osteological analysis confirms that some thirty individuals of both sexes and various ages were buried there. The structure of the monument is that of a rectangular dolmen. This paper discusses the discovery of this specific site, and explores the existence of this type of monument in a Gotland context. Furthermore, is this really the only megalith on Gotland, or are more of these structures yet to be recognised? Finally, one may ask if the Neolithic way of life really was successful on Gotland.

    Most patients with Graves' orbitopathy have mild disease that requires no or minimal intervention. For the minority of patients with moderate or severe disease, multiple medical and surgical treatments may be required at different stages. It is crucial that such patients are monitored closely and treatments applied with care in the right sequence. Medical treatments should be used as early as possible and only during the active phase of the disease. Rehabilitative surgery is indicated in the inactive phase of the disease and should follow the sequence: surgical decompression followed by eye muscle surgery, followed by lid surgery. Delivery of care in a coordinated fashion that makes use of best available expertise is important and best implemented through a Combined Thyroid Eye clinic.

    The article analyzes the 660 grave in Megara Iblea, a Greek colony in Sicily, in which a woman has been buried. On her breast a magnificent neckless was found, made of amulets recalling the travel of the sun during the summer solstice. Some objects allude to solar cults (a cock; round pendants), others seem to came from Gallia and Macedonia (summer far West and East), others recall archeological contexts such as tombs in Marvinci, in the Vardar Valley, and allude to relations with female practices of medicine and magic and to female roles characterized by extraordinary powers, due to being descendants of the Sun god. These solar symbols, joint with the discovery of many little objects, typical of children burials, allow to hypotize a relation with the cult of Mater Matuta and seem to point out a difficult or anomalous pregnancy or birth.

  9. Association between polymorphisms in the TSHR gene and Graves' orbitopathy.

    Directory of Open Access Journals (Sweden)

    Beata Jurecka-Lubieniecka

    Full Text Available BACKGROUND: Graves' orbitopathy (GO as well as Graves' disease (GD hyperthyroidism originate from an autoimmune reaction against the common auto-antigen, thyroid-stimulating hormone receptor (TSHR. GO phenotype is associated with environmental risk factors, mainly nicotinism, as well as genetic risk factors which initiate an immunologic reaction. In some patients GO is observed before diagnosis of GD hyperthyroidism, while it can also be observed far after diagnosis. The intensity of GO symptoms varies greatly in these patients. Thus, the pathogenesis of GD and GO may correlate with different genetic backgrounds, which has been confirmed by studies of correlations between GO and polymorphisms in cytokines involved in orbit inflammation. The aim of our analysis was to assess genetic predisposition to GO in young patients (age of diagnosis ≤30 years of age, for whom environmental effects had less time to influence outcomes than in adults. METHODS: 768 GD patients were included in the study. 359 of them had clinically evident orbitopathy (NOSPECS ≥2. Patients were stratified by age at diagnosis. Association analyses were performed for genes with a known influence on development of GD - TSHR, HLA-DRB1, cytotoxic T-lymphocyte antigen 4 (CTLA4 and lymphoid protein tyrosine phosphatase (PTPN22. RESULTS: The rs179247 TSHR polymorphism was associated with GO in young patients only. In young GO-free patients, allele A was statistically more frequent and homozygous carriers had a considerable lower risk of disease incidence than patients with AG or GG genotypes. Those differences were not found in either elderly patients or the group analyzed as a whole. CONCLUSIONS: Allele A of the rs179247 polymorphism in the TSHR gene is associated with lower risk of GO in young GD patients.

  10. Atypical Clinical Manifestations of Graves' Disease: An Analysis in Depth

    Directory of Open Access Journals (Sweden)

    Mohamed Osama Hegazi

    2012-01-01

    Full Text Available Over the past few decades, there has been an increase in the number of reports about newly recognized (atypical or unusual manifestations of Graves' disease (GD, that are related to various body systems. One of these manifestations is sometimes the main presenting feature of GD. Some of the atypical manifestations are specifically related to GD, while others are also similarly seen in patients with other forms of hyperthyroidism. Lack of knowledge of the association between these findings and GD may lead to delay in diagnosis, misdiagnosis, or unnecessary investigations. The atypical clinical presentations of GD include anemia, vomiting, jaundice, and right heart failure. There is one type of anemia that is not explained by any of the known etiological factors and responds well to hyperthyroidism treatment. This type of anemia resembles anemia of chronic disease and may be termed GD anemia. Other forms of anemia that are associated with GD include pernicious anemia, iron deficiency anemia of celiac disease, and autoimmune hemolytic anemia. Vomiting has been reported as a presenting feature of Graves' disease. Some cases had the typical findings of hyperthyroidism initially masked, and the vomiting did not improve until hyperthyroidism has been detected and treated. Hyperthyroidism may present with jaundice, and on the other hand, deep jaundice may develop with the onset of overt hyperthyroidism in previously compensated chronic liver disease patients. Pulmonary hypertension is reported to be associated with GD and to respond to its treatment. GD-related pulmonary hypertension may be so severe to produce isolated right-sided heart failure that is occasionally found as the presenting manifestation of GD.

    2012-01-01

    Full Text Available Much of the debate over stateness in Latin America assumes that states should sustain basic levels of stability, and if they cannot, the question is why not. This article departs from the assumption of stability, by asking how the relationship between states and other actors has evolved over time. This departure requires a shift in focus: from stateness as referring to states and how they should operate, to stateness as referring to the relationships between states and other actors, and how they change over time. The article argues that such relationships can be understood as emergent complex adaptive systems (CAS, and considers three specific CAS mechanisms: networks, arms races, and moral hazards. This conceptual shift in how to think about states is especially challenging in a region historically accustomed to hierarchical governance.Buena parte del debate sobre la estatalidad en América Latina presupone que los estados deben mantener niveles básicos de estabilidad, y que si no pueden hacerlo, la pregunta es por qué no. Este artículo se aleja del supuesto de la estabilidad, al preguntar cómo la relación entre los estados y otros actores ha evolucionado con el tiempo. Esto requiere un cambio de enfoque: de estatalidad que se refiere a los estados y cómo debieran funcionar, a la estatalidad en referencia a las relaciones entre los estados y otros actores, y cómo éstas cambian con el tiempo. El artículo sostiene que este tipo de relaciones se puede entender como sistemas complejos adaptativos (SCA emergentes, y considera tres mecanismos específicos de SCA: redes, carreras armamentistas y peligros morales (moral hazards. Este cambio conceptual en laforma de pensar acerca de los estados es especialmente difícil en una región históricamente acostumbrada a la gobernanza jerárquica.

    Full Text Available The recent and continuing reduction in glacier ice cover in high mountains and thaw of alpine permafrost may have an impact on many potentially hazardous processes. As glaciers thin and retreat, existing ice- and moraine-dammed lakes can catastrophically empty, generating large and destructive downstream floods and debris flows. New ice-dammed lakes will form higher in mountain catchments, posing additional hazards in the future. The magnitude or frequency of shallow landslides and debris flows in some areas will increase because of the greater availability of unconsolidated sediment in new deglaciated terrain. Continued permafrost degradation and glacier retreat probably will decrease the stability of rock slopes.La reciente y continua reducción de la cobertura glaciaria en alta montaña y el deshielo del permafrost pueden tener un impacto negativo en muchos procesos potencialmente peligrosos. A medida que los glaciares reducen su espesor y retroceden, los lagos formados por diques de hielo o morenas pueden vaciarse catastróficamente, resultando en grandes y destructivas inundaciones o flujos detríticos río abajo. Nuevos diques de hielo van a formarse en zonas más altas de las cuencas montañosas, generando peligros adicionales en el futuro. La magnitud o frecuencia de movimientos en masa superficiales y flujos detríticos va a aumentar en algunas áreas debido a la mayor disponibilidad de materiales no consolidados en nuevos terrenos desglasados. La degradación continua del permafrost y el retiro de glaciares probablemente va a disminuir la estabilidad de laderas rocosas.

    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.

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

    Directory of Open Access Journals (Sweden)

    Miloš Žarković

    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.

    Radioiodine therapy is often employed for treatment of patients with relapse of hyperthyroidism due to Graves' disease, after previous thyroid surgery. Little is known about the outcome of this treatment compared to patients with no previous surgery. A total of 20 patients who had received surgical...... treatment for Graves' hyperthyroidism 1-46 years previously and with relapse of the hyperthyroidism, and 25 patients with hyperthyroidism due to Graves' disease and no previous thyroid surgery were treated with radioiodine, following the same protocol. Early after treatment the previously operated patients...

  18. Strategies of radioiodine therapy for Graves' disease

    Several therapeutic options are available for the treatment of Graves' disease (GD), including long-term antithyroid drug medication (ATD), near-total resection (NTR) and radioiodine therapy (RIT). These treatments are used with different frequencies depending on geographical location, size of the goitre, age of the patient and experience of the physician. It should be noted that RIT is still being applied more frequently in the United States than in Europe. Despite the fact that RIT was introduced as long ago as 1941, several questions are still the subject of debate: Should a fixed dose or a calculated dose be used. If the dose is calculated, how many Grays (Gy) should be delivered to the thyroid? What is the goal of RIT in GD? Which factors, including ATD, influence the outcome of RIT? Is RIT appropriate in GD with Graves' ophthalmopathy (GO)? Although not all these questions have been answered yet, conclusions can be derived regarding a general strategy for use of RIT in GD. As with surgery, the goal of RIT in GD is euthyroidism with or without L-thyroxine medication. There is a clear advantage of dose calculation over use of a fixed dose because the only factor influencing the outcome is the dose delivered to a certain thyroid volume. To minimise recurrent hyperthyroidism, an ablative approach using a delivered dose of 250 Gy is widely accepted. Beside pretherapeutic T{sub 3} levels, thyroid volume and 24-h thyroid uptake, ATD may influence the outcome of RIT. Today it is accepted by most thyroidologists that, if ATD medication is necessary in overt hyperthyroidism, it should be withdrawn at least 2 days before RIT. In patients with GD and GO, RIT may worsen GO. If RIT is performed in GO it should be done under a 3-month steroid medication regimen. In conclusion, RIT can be considered an appropriate and cost-effective therapy in GD, although the decision regarding treatment should be taken on an individual basis, paying due respect to the course and

    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).

  1. Cradle-to-Grave Logistic Technologies for Exploration Missions

    Human exploration missions under study are very limited by the launch mass capacity of exiting and planned vehicles. The logistical mass of crew items is typically considered separate from the vehicle structure, habitat outfitting, and life support systems. Consequently, crew item logistical mass is typically competing with vehicle systems for mass allocation. NASA is Advanced Exploration Systems (AES) Logistics Reduction and Repurposing (LRR) Project is developing four logistics technologies guided by a systems engineering cradle-to-grave approach to enable used crew items to augment vehicle systems. Specifically, AES LRR is investigating the direct reduction of clothing mass, the repurposing of logistical packaging, the processing of spent crew items to benefit radiation shielding and water recovery, and the conversion of trash to propulsion supply gases. The systematic implementation of these types of technologies will increase launch mass efficiency by enabling items to be used for secondary purposes and improve the habitability of the vehicle as the mission duration increases. This paper provides a description, benefits, and challenges of the four technologies under development and a status of progress at the mid ]point of the three year AES project.

    Sheehan's syndrome (SS), which is an important cause of hypopituitarism, is common in developing countries. The most common presentation is the absence of lactation and amenorrhea. Hypothyroidism rather than hyperthyroidism is the usual expected phenomenon in SS. Postpartum hyperthyroidism is also common and Graves' disease (GD) is an important cause of postpartum hyperthyroidism. Here we report a case of a 22-year-old female patient in our clinic presented symptoms of amenorrhea, lack of lactation, palpitations and sweating. Her physical examination revealed goiter, moist skin and proptosis. Her laboratory evaluation showed suppressed thyroid stimulating hormone, elevated levels of free thyroxine and free triiodothyronine. Thyroid antibodies were positive. Tec 99m thyroid scintigraphy results were gland hyperplasia and increased uptake consistent with GD. She gave birth 7 months ago; after delivery she had a history of prolonged bleeding, amenorrhea and inability to lactate. She had hypogonadotropic hypogonadism, hyperprolactinemia and growth hormone deficiency. Serum cortisol and adrenocorticotropic hormone levels were normal. Her magnetic resonance imaging was empty sella. Our diagnosis was GD co-existing with SS. GD with concomitant hypopituitarism is rare but has been described previously, but there are no reports of GD occurring with SS. In this case study, we report a patient with GD associated with SS.

    Graves' disease (GD) is extremely rare in children younger than 4 years of age, but if not recognized and treated it can seriously interfere with growth and development. We report three unrelated children, all females, in whom GD occurred before the age of 3. These children presented with goiter, exophthalmos, tachycardia, and hyperactivity. Moreover, one showed a severe psychomotor delay, and had previously undergone surgery due to craniosynostosis; the other two manifested a language delay. All had high thyroid hormones and thyrotropin receptor antibody (TRAb) serum levels that clearly indicated autoimmune hyperthyroidism. In all of them, the disease presumably had developed during the first or second year of life. No maternal history of GD was present in two. The third child was born to a mother affected with GD during pregnancy, but it is likely that her GD began to develop after 6 months of life. These children are being treated with methimazole, and treatment is still necessary after 32 months. TRAb levels were persistently high at follow-up. Psychological evaluation including language development at follow-up was appropriate for age in two children; the third child improved, but severe mental retardation is still evident. GD assessment in early childhood also needs to focus on psychological evaluation. Pediatricians should be aware of the possibility of permanent brain damage and craniosynostosis due to hyperthyroidism in infancy.

    The aim of the present work was to study the relationship between thyroid low echogenicity, the thyroid blood flow by color-Doppler (CD) and histological features in patients with Graves' disease (GD). Thyroid ultrasonography and CD was performed on 28 patients with GD. In 5 patients has been compared CD with histology. The thyroid volume was higher in 100% of patients with GD at the onset rather than in euthyroidism. Diffuse hypoechogenicity of the thyroid was discovered in 100% of patients with GD at the onset and it persisted in 57.1% of patients that became euthyroid after therapy. Qualitative CD resulted in different patterns that were classified as follow: pattern A ("thyroid inferno") in 17 patients (60.7%); pattern B (mildly increased of parenchymal blood flow) in 11 patients (39.3%). In the 5 histological proven cases, in the pattern A (3 cases) there was a diffuse microfollicular hyperplasia with functional activation notes. There was lymphocytic infiltration. While in the pattern B (two cases) there were a non-follicular hypercellular nodule with pseudocapsule and rare colloid. We conclude that there are two different histological types with different CD patterns in GD.

    Each of the three major therapies for Graves' disease has its own advantages, disadvantages, indications, and contraindications. Today, radioactive iodine (RAI) therapy is the most commonly employed means of therapy for Graves' disease in the United States, with approximately 70% of patients so treated after initial presentation and an additional fraction of arguably 10-15% treated with RAI after failure of antithyroid drugs or surgery. RAI therapy is acknowledged to have the clear-cut advantage of being safe, with low morbidity and cost. The indications for RAI therapy are clear and noncontroversial for most patients with Graves' disease. Moreover, RAI treatment is employed by some thyroidologists for subclinical thyrotoxicosis (normal T4 or T3 but immeasurable TSH), particularly in patients > age 45 due to risks of atrial fibrillation. RAI therapy is not considered indicated or is contraindicated during breast feeding and in pregnancy, subacute thyroiditis, postpartum thyroiditis, struma ovarii, pituitary (TSH-driven) hyperthyroidism, euthyroid, hyperthyroxinemia, and thyroid hormone resistance. Opinions vary on the use of RAI therapy in children with Graves' disease; generally, a lower age cutoff of 17 years is acceptable in most clinics. Even more controversial is whether RAI therapy in the presence of Graves' ophthalmology constitutes a risk for worsening ophthalmopathy. Resolution of this latter issue awaits more definitive studies, but RAI therapy is likely to remain the first choice for most patients with Graves' disease.

  6. Prognostic factors of the outcomes of subtotal thyroid resection in graves disease

    Full Text Available The long-term results of subtotal resection of thyroid gland on 82 patients with Graves' disease were studied. There was analysed the influence of three factors on outcome at Graves' disease: volume of a thyroid gland before operation, morphological structure of thyroid tissue and volume of thyroid remnant. Outcomes of subtotal resection of thyroid gland were studied on the basis of thyrotropic hormone level of blood in 3, 6, 12 months, 2 and 3 years after operation. Based on research it has been established that the volume of thyroid gland before operation does not influence to outcome of subtotal resection of thyroid gland with Graves' disease. Morphological changes of removed thyroid tissue in the form of colloidal nodules at patients with Graves' disease statistically significantly raise risk of development of postoperative complications after subtotal resection of thyroid gland. The surgeon defining the volume of thyroid rem-nant durng the operation could be mistaken as towards it's increase so towards it's reduction, with an average deviation about 35%. Various outcomes of subtotal resection of thyroid gland at the same volume of thyroid remnant let us conclude that this out-come depends more on intensity of autoimmune process rather than on the volume of thyroid remnant. According modern views to aetiology and patogenesis of Graves' disease, the optimum volume of operation at Graves' disease is thyroidectomy.

    Full Text Available The three major forms of treatment for Graves thyrotoxicosis are antithyroid drugs, radioactive iodine therapy and thyroidectomy. Surgery is the definitive treatment for Graves thyrotoxicosis that is generally recommended when other treatments have failed or are contraindicated. Generally, thyrotoxic patients should be euthyroid before surgery to minimize potential complications which usually requires preoperative management with thionamides or inorganic iodine. But several cases of refractory Graves' disease have shown resistance to conventional treatment. Here we report a 40-year-old female patient with Graves' disease who complained of thyrotoxic symptoms for 7 months. Her thyroid function test and thyroid autoantibody profiles were consistent with Graves' disease. One kind of thionamides and β-blocker were started to control her disease. However, she was resistant to nearly all conventional medical therapies, including β-blockers, inorganic iodine, and two thionamides. She experienced hepatotoxicity from the thionamides. What was worse is her past history of serious allergic reaction to corticosteroids, which are often used to help control symptoms. A 2-week regimen of high-dose cholestyramine improved her uncontrolled thyrotoxicosis and subsequent thyroidectomy was successfully performed. In conclusion, cholestyramine could be administered as an effective and safe adjunctive agent for preoperative preparation in patients with severe hyperthyroid Graves's disease that is resistant to conventional therapies.

It is caused by an arbovirus and transmitted by an arthropod; there are two known epidemiologic modalities, and it has an endemic area that comprises most of South America and part of the African continent. In Costa Rica the last outbreak of yellow fever was in the fifties. The physiopathology of yellow fever is not well known. Most of the infections are symptomatic and have a high mortality that varies from outbreak to outbreak. The diagnosis is definitely confirmed by serology and although this test isn’t performed in Costa Rica, the suspicious samples are sent to Panamanian labs. Taking into consideration its high mortality and the lack of specific treatment, it’s obvious that the only way to deal with yellow fever is to get rid of the vector and prevention with massive vaccination in endemic areas. Yellow fever continues to be an entity that considerably affects public health in several countries; Costa Rica has quite a few conditions that will ease its appearance and dissemination, that’s why this is a disease which’s characteristics are convenient to keep handy

    Members of the American Thyroid Association were invited to participate in a survey of the management of Graves' disease. One primary case and several variations were provided, which differed in respect to age, sex, goiter size, severity, etc. The questionnaire was based on the format used in a similar survey of members of the European Thyroid Association. The aim of the survey was to determine (1) how expert thyroidologist employ diagnostic procedures for this disorder, and (2) the choice of therapy of the three treatment options and its manner of implementation. Questionnaires were sent only to clinically active members. The overall response rate was 62%. Data analysis was possible on 52% of members surveyed and was performed using SPSS and a specific Fortran program. In the laboratory evaluation of the primary case a radioiodine uptake, scan, serum total T4, and basal TSH were requested by 92%, 47%, 83%, and 66%, respectively, with 84% of respondents using an ultrasensitive TSH assay. For management of the primary case, radioiodine treatment was the first choice of 69% of the respondents. Antithyroid drugs were used briefly (3-7 days) before 131I by 28%, whereas 41% said they would employ thioureas after 131I. Of those using 131I, 66% tailored the dose to achieve euthyroidism as the goal of therapy, while 34% aimed for hypothyroidism requiring T4 replacement. Only 30% of respondents chose thioureas as a first line of treatment (72% propylthiouracil; 28% tapazole). The duration of drug therapy was a predetermined fixed interval for 80% of the respondents, with 90% treating for 1-2 yr. Other specific trends in diagnostic approach and therapeutic preferences were identified for the eight variations on the primary case problem.

  11. Lithium as an Alternative Option in Graves Thyrotoxicosis

    2015-01-01

    Full Text Available A 67-year-old woman was admitted with signs and symptoms of Graves thyrotoxicosis. Biochemistry results were as follows: TSH was undetectable; FT4 was >6.99 ng/dL (0.7–1.8; FT3 was 18 pg/mL (3–5; TSI was 658% (0–139. Thyroid uptake and scan showed diffusely increased tracer uptake in the thyroid gland. The patient was started on methimazole 40 mg BID, but her LFTs elevated precipitously with features of fulminant hepatitis. Methimazole was determined to be the cause and was stopped. After weighing pros and cons, lithium was initiated to treat her persistent thyrotoxicosis. Lithium 300 mg was given daily with a goal to maintain between 0.4 and 0.6. High dose Hydrocortisone and propranolol were also administered concomitantly. Free thyroid hormone levels decreased and the patient reached a biochemical and clinical euthyroid state in about 8 days. Though definitive RAI was planned, the patient has been maintained on lithium for more than a month to control her hyperthyroidism. Trial removal of lithium results in reemergence of thyrotoxicosis within 24 hours. Patient was maintained on low dose lithium treatment with lithium level just below therapeutic range which was sufficient to maintain euthyroid state for more than a month. There were no signs of lithium toxicity within this time period. Conclusion. Lithium has a unique physiologic profile and can be used to treat thyrotoxicosis when thionamides cannot be used while awaiting elective radioablation. Lithium levels need to be monitored; however, levels even at subtherapeutic range may be sufficient to treat thyrotoxicosis.

El fenómeno se agrava cuando se reduce el índice de infiltración debido a lluvias previas. Estos torrentes se generan en la zona montañosa, con fuerte pendiente. La extensión del área de las unidades activas en el piedemonte de la sierra de Zonda se determinó a través del estudio de fotografías aéreas y de mapas con la topografía de la zona. Las áreas activas se ubicaron topográficamente por debajo de las unidades más antiguas del piedemonte. En la planicie aluvial pedemontana, donde se encuentra la zona urbana y rural, los aluviones se han restringido a las calles 13 y 15, orientadas paralelas a la dirección de flujo. Durante las lluvias torrenciales, estas calles se convierten en verdaderos cauce fluviales, mientras que en las calles orientadas perpendicularmente a las anteriores, los daños son mayores.En este trabajo se realiza la evaluación de los aspectos hidrológicos de una cuenca de régimen torrencial, como es la del arroyo La Lechuza, causante de la mayoría de los daños en el departamento.

    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

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 construct an animal model of Graves' disease (GD) by immunizing BALB/c mice with hM12 cells co-expressing major histocompatibility complex (MHC) class Ⅱ molecules and human thyrotropin receptor (TSHR) molecules. Methods BALB/c mice in experimental group (H-2d) were immunized with hM12 cells Intraper-itoncally every 2 weeks for six times, while mice in control group were immunized with M12 cells. Five weeks later, the thyroids were histologically examined, and serum samples were tested for thyroid-stimulating antibodies (TSAb) and thyroid hormone levels. Results One BALB/c mouse in experimental group developed Graves'-like disease. Total T4 and T3 levels in this mouse were above the upper limit of normal, TSAb activity was displayed in its serum. The thyroid histologically showed the features of thyroid hyperactivity including thyrocyte hypercellularity and colloid absorption.None of control mice developed Graves'-like disease. Conclusion An animal model with some characteristics of human Graves' disease was successfully induced and the model will facilitate studies aimed directly at understanding the patho-genesis of autoimmunity in Graves' disease.

    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.

  1. The Roma: People without a Home or Grave

    Full Text Available Although the Roma have been living in Europe for centuries, they still face rejection by majority populations, being treated as undesirable strangers in almost all European countries. Written evidence of their arrival can be traced back to the fourteenth and fifteenth centuries. There are many legends and myths about their origins and reasons for emigrating from their country of origin. Until recently, the Roma transmitted their own history only as oral tradition. One of the best-known contemporary Roma intellectuals, journalist and writer Rajko Djurić, picturesquely explains the importance of the Romany language for further exploration of Roma culture and their origin: “Romany is the only book they brought from India; it constitutes their collective memory and reflects the views of this people, to themselves, to the world, and to other peoples. Their language is an inventory of the material and spiritual culture to which they once belonged, and contains elements of culture of other peoples that they came into contact with during their long and yet insufficiently studied journey.” When the Roma arrived in Europe, their lifestyle differed significantly from that of other European peoples. As a result, majorities and other groups in Europe intervened in their lives for centuries. They were forced to abandon their nomadic way of life. In the past, authorities often expelled them from their territory and they did not enjoy legal protection when violence or crimes were committed against them. Living in isolated settlements, excluded from social life, segregated, and discriminated against by others, they lived on the margins as a people without a home or a grave. At the same time, they established their parallel world as a system of social norms valid within their community, and within it all non-Roma were perceived as gadje ‘outsiders’. Roma legends explain the reasons for their nomadic way of life: they contain stories of persecution and

  2. 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.

  5. Postpartum thyrotoxicosis in a patient with Graves' disease. Association with low radioactive iodine uptake

    Energy Technology Data Exchange (ETDEWEB)

    Eckel, R.H.; Green, W.L.

    1980-04-11

    A patient with previously diagnosed Graves' hyperthyroidism had a transient episode of thyrotoxicosis three months postpartum. This was associated with a diffusely enlarged thyroid gland, a rise in antithyroid microsomal antibody titer, a 24-hour radioactive iodine uptake (RAIU) of 1%, and an aspiration biopsy specimen suggestive of chronic lymphocytic thyroiditis. An alternative cause for the depressed RAIU was not discovered. This case would suggest that patients with previously diagnosed Graves' disease can have thyrotoxicosis without an enhanced RAIU and that the postpartum thyrotoxin syndrome may involve an immunologic injury causing a release of performed thyroid hormone.

    2013-05-01

    Clinical hyperthyroidism during the first trimester of pregnancy due to Graves' disease can be associated with maternal, obstetrical and fetal complications, indicating an active treatment to restore normal thyroid function. Antithyroid drugs are the first line treatment in pregnant women with hyperthyroidism. Due to the increased congenital malformations reported in neonates after first-trimester carbimazole/methimazole treatment and propylthiouracil associated hepatotoxicity, the recommended treatment for pregnant women with hyperthyroid Graves' disease is propylthiouracil during the first trimester of pregnancy and following the first trimester, consideration should be given switching to carbimazole/methimazole during the second part of gestation.

    Full Text Available The Hazard Analysis and Critical Control Point (HACCP is a preventive system which tries to ensure the food safety and wholesomeness and allows us product protection and flaw correction. Quality control costs are therefore reduced, since final super-control becomes almost unnecessary. In this work the hazards that can be found in a processing line of virgin olive oil are described, as well as the preventive actions which can be taken in the oil mill, the surveillance systems to be implemented, the eventual corrective actions and the records to be kept by the plant. The implementation of these principles would make possible, for any oil mill (regardless of the system used for solid-liquid separation, a production self-control based on the HACCP system.El Análisis de Peligros y Puntos de Control Crítico (APPCC es un sistema preventivo que trata de garantizar la seguridad e inocuidad alimentaria, y que permite la protección del producto y la corrección de fallos, mejorando los costes de calidad por defectos y ahorrando casi el supercontrol final.

    1984-06-01

    From 1977 to 1982, 315 patients suffering from thyrotoxicosis with diffuse and/or nodular goitre or Graves' disease were treated with /sup 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 /sup 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 /sup 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.

    2011-11-01

    Full Text Available Abstract Background Limited data are available on the association between vitiligo and autoimmune thyroid disease in pediatric patients. In addition, reported studies of pediatric patients have been based on a population known to have vitiligo and subsequently evaluated for the presence of thyroid function abnormalities. Methods A retrospective chart review was performed on 333 children who had been followed for thyroid disorders by endocrinologists at the Yale Pediatric Thyroid Center over the last 5 years for autoimmune thyroid disease. Demographical and clinical features of patients found to have thyroid disease and vitiligo were recorded. These studies were approved by the Yale Human Investigation Committee. Results Of the total 333 children and adolescents, 9 (2.7% were noted to have vitiligo. Four patients (44% had Graves' disease and 5 patients (66% had Hashimoto's thyroiditis. For patients with Graves' disease and vitiligo, the average age of onset of thyroid disease was young at 4 ± 0.7 years, and the diagnosis of vitiligo usually preceded that of thyroid disease. For children with Hashimoto's thyroiditis and vitiligo, thyroid disease was diagnosed at an average age of 13.25 ± 2.8 years. Conclusion In our population, 4.6% of children with Graves' disease and 2.0% of children with Hashimoto's thyroiditis had vitiligo. Interestingly, when vitiligo presents with Graves' disease, it occurs in younger rather than older children.

  6. Subclinical Hypothyroidism after 131I-Treatment of Graves' Disease: A Risk Factor for Depression?

    Directory of Open Access Journals (Sweden)

    Jing Yu

    Full Text Available Although it is well accepted that there is a close relationship between hypothyroidism and depression, previous studies provided inconsistent or even opposite results in whether subclinical hypothyroidism (SCH increased the risk of depression. One possible reason is that the etiology of SCH in these studies was not clearly distinguished. We therefore investigated the relationship between SCH resulting from 131I treatment of Graves' disease and depression.The incidence of depression among 95 patients with SCH and 121 euthyroid patients following 131I treatment of Graves' disease was studied. The risk factors of depression were determined with multivariate logistic regression analysis. Thyroid hormone replacement therapy was performed in patients with thyroid-stimulating hormone (TSH levels exceeding 10 mIU/L.Patients with SCH had significantly higher Hamilton Depression Scale scores, serum TSH and thyroid peroxidase antibody (TPOAb levels compared with euthyroid patients. Multivariate logistic regression analysis revealed SCH, Graves' eye syndrome and high serum TPO antibody level as risk factors for depression. L-thyroxine treatment is beneficial for SCH patients with serum TSH levels exceeding 10 mIU/L.The results of the present study demonstrated that SCH is prevalent among 131I treated Graves' patients. SCH might increase the risk of developing depression. L-thyroxine replacement therapy helps to resolve depressive disorders in SCH patients with TSH > 10mIU/L. These data provide insight into the relationship between SCH and depression.

    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

    2009-01-01

    Full Text Available Introduction. The clinical diagnostic of Graves ophthalmopathy is based on the association of ocular signs and the disease of the thyroid gland. The evolution of the disease involves the development of eye globe protrusion, extraocular muscle thickening pressuring the optic nerve, which can result in its thickness. Objective. The aim of the paper is to find whether the retrobulbar optic nerve thickened and if there was a correlation between its possible thickening and the thickness of the muscles in Graves ophthalmopathy. We also wished to test the theory of compressive aetiology of such thickening using a 30-degree test. Methods. We examined 28 patients with Graves ophthalmopathy. The thickness of the retrobulbar optic nerve was measured by ultrasound on a B-scan using the Schraeder's method and by the largest thickness of the internal muscle. Results. The thickness of the retrobulbar portion of the optic nerve in the 52 analyzed eyes with signs of the disease ranged between 3.24 mm to 6.30 mm, with median of 5.13 mm, indicating that the majority of the patients had optic nerve thickening rating at this value. Forty-eight eyes had a marked retrobulbar optic nerve thickening, with the thickening over 4 mm, while in 4 eyes with signs of Graves ophthalmopathy the thickness of the optic nerve was within normal limits. We detected that 92.3% of the patients with muscular thickening also had a directly proportional thickening of the retrobulbar optic nerve. By using the 30-degree test we confirmed the diagnosis of compressive neuropathy. Conclusion. Patients with Graves ophthalmopathy and thickened muscles, also have a thickening of the retrobulbar optic nerve; the rate of the thickness directly depends on the degree of the muscular thickness. The word is of compressive neuropathy, i.e. the thickness of the optic nerve is the result of subarachnoid fluid stasis caused by the compression on the optic nerve.

    2009-08-13

    Warm antibody autoimmune hemolytic anemia is due to the presence of warm agglutinins that react with protein antigens on the surface of red blood cells causing premature destruction of circulating red blood cells. We report the first case of concurrent reactive arthritis, Graves' disease, and autoimmune hemolytic anemia. A 40-year-old man with reactive arthritis, Graves' disease, type 2 diabetes mellitus, mitral valve prolapse, and Gilbert's disease presented with a one month history of jaundice, fatigue, and black stools. After diagnosis of warm autoimmune hemolytic anemia, the patient was started on prednisone 1 mg/kg with rapid improvement in his anemia and jaundice. Our subject's mother and possibly his maternal grandmother also had autoimmune hemolytic anemia, which raises the possibility of hereditary autoimmune hemolytic anemia, a rarely reported condition.

    Shirley Graves M.D., D.Sc. (honorary) (1936), Professor Emeritus of Anesthesiology and Pediatrics at the University of Florida, was one of the most influential women in medicine in the 1960 and 1970s, a time when the medical profession was overwhelmingly male-dominated. In today's society, it is hard to believe that only 50 years ago, women were scarce in the field of medicine. Yet Dr. Graves was a pioneer in the fields of pediatric anesthesia and pediatric critical care medicine. She identifies her development of the pediatric intensive care unit and her leadership in the Division of Pediatric Anesthesia at the University of Florida as her defining contributions. Through her journal articles, book chapters, national and international lectures, and leadership in the American Society of Anesthesiology and the Florida Society of Anesthesiology, she inspired a generation of men and women physicians to conquer the unthinkable and break through the glass ceiling.

  18. Scientific studies on pottery and pro-porcelain from group of graves in Henglingshan, Guangdong Province

    2009-01-01

    The findings of the Henglingshan group of graves, Guangdong Province, were appraised as one of the ten major archaeological excavations in 2000. The pottery and proto-porcelain samples excavated from the group of graves in Henglingshan are very important for studying the development history of Guang-dong ceramics. In this paper, the chemical compositions, micro-structure and physical properties of the samples were systematically analyzed. The results were subjected to multivariate statistical analysis. Different compositional patterns were found for specimens from different periods. The reasons for these variations were discussed. In addition, compared with the pottery and proto-porcelain samples from different production sites in other provinces of China, the obvious regional characters and unique law of the development for ancient ceramics of Guangdong were also discussed.

    The main goal of therapy for Graves' orbitopathy (GO) is to restore visual function and to improve quality of life (QOL); therefore, the idea of self-assessment of eye changes by the patient has been developed. We developed a validated Polish version of the GO-QOL questionnaire (GO-QOLpl). As an original version we used the English version of GO-QOL, which consists of 15 questions summarised in two subscales. GO-QOLpl was translated and validated in accordance with standard principles for translation of patient-reported outcomes (PRO). GO-QOLpl is a linguistically validated version of the original GO-QOL questionnaire, which is recommended by the European Group of Graves' Orbitopathy (EUGOGO). We strongly support the use of GO-QOLpl for the assessment of QOL among Polish patients with GO in clinical practice.

  20. The philosopher Socrates had exophthalmos (a term coined by Plato) and probably Graves' disease.

    According to a previously published theory, Socrates was afflicted with temporal lobe epilepsy since his childhood. Plato, Xenophon, and Aristoxenus described Socrates as having exophthalmos, probably diplopia, and some symptoms compatible with hyperthyroidism. Using these data, we theorize that Socrates had Graves' disease. In order to determine a cause of his temporal lobe epilepsy, we speculate that the philosopher also had autoimmune thyroiditis and Hashimoto encephalopathy during his childhood and his epilepsy may have been a sequel to this hypothesized encephalopathy.

    Graves' orbitopathy (GO) is uncommon, but responsible for considerable morbidity. A coordinated approach between healthcare professionals is required in order to meet the needs of patients. Early diagnosis can be achieved by a simple clinical assessment. Low-cost effective interventions can be initiated by generalists, which may improve outcomes. Moderate-to-severe GO should be referred to specialised centres. Recommendations for clinical diagnosis, initial management and referral pathways are highlighted.

    The aim of this study was to investigate the predictive role of the orbital somatostatin receptor scintigraphy with (99m)Tc-EDDA/HYNIC-TOC ((99m)Tc-TOC) to detect clinical stage of Graves' ophthalmopathy and the response to corticosteroid therapy. The subjects of the experiment were 46 patients with Graves' ophthalmopathy (GO) and four volunteers without eye disease or GO as the normal group (NG). Single photon emission computed tomography (SPECT), computed tomography (CT) and the left and right lateral position planar imaging of the heads of the all subjects were obtained 4 h after the intravenous injection of 555 MBq of (99m)Tc-TOC. The (99m)Tc-TOC SPECT/CT was repeated 3 months later. 35 (35/46) patients were received corticosteroid therapy (prednisolone, 10 mg po tid ) for 3 months, however, the other 11 patients as control groups did not receive any treatment. The treatment effect was evaluated both by the orbital (99m)Tc-TOC uptake and NOSPECS. A significant decrease in the O/OC ratio was observed in 22 GO patients between pre- and post-treatment (1.64 ± 0.13 vs. 1.21 ± 0.09, P TOC scintigraphy is a feasible technique to estimate the Graves' ophthalmopathy activity and predict the response to subsequent corticosteroid therapy in GO patients.

    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)

    Corticosteriods are usually given for management of Graves' ophthalmopathy, but they have many and serious side-effects. By comparison, retrobulbar irradiation is well tolerated, although its efficacy has been evaluated only in uncontrolled studies. Therefore, the authors did a double-blind randomized trial, in which 28 patients with moderately severe Graves' ophthalmopathy were treated with a 3-month course of oral prednisone and sham irradiation, and 28 received retrobulbar irradiation (20 Gy) and placebo capsules. Therapeutic outcome, assessed twenty-four weeks after the start of treatment, was determined by the change in the highest NOSPECS class. A successful outcome was observed in 14 prednisone-treated and in 13 irradiated patients. Responders to treatment (but not nonresponders) in both groups showed improvements in total and subjective eye score and a decrease in eye-muscle volume. Response to either treatment was due largely to changes in soft-tissue involvement and eye-muscle motility. Radiotherapy and oral prednisone appear to be equally effective as initial treatment in patients with moderately severe Graves' ophthalmopathy. In view of its better tolerability, radiotherapy should be considered the treatment of first choice.

    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.

    During the excavation of the Spanish Civil War mass grave at La Pedraja (Burgos, Spain), 104 individuals were found interred within it, 45 of which displayed brains that were preserved but dehydrated and reduced in size. This exceptional finding has resulted in the formation of a multidisciplinary team, with the aim of obtaining as much information as possible and to primarily understand the taphonomic phenomena that has led to the preservation of these brains. The following types of analyses were undertaken on three of these brains: macroscopy, histology, radiology, chemical-toxicology, genetics, chemical analysis of the soil and 3D modelling for stereolithography. The historical context was considered, plus all archaeological and other forensic data provided by the investigation of the mass grave. The results of the analyses on these morphologically identifiable human brains confirmed the presence of nerve structures, fatty acids, and in one case ante-mortem evidence for an intracranial haemorrhage. The fatty acid profile corresponds to the process of saponification. Therefore, the interpretation is that the preservation of these brains at the mass grave of La Pedraja was due to the saponification process, which was influenced by the manner and cause of death, the chemical composition of the brain, the physicochemical properties of the soil and the meteorological conditions at the time.

  17. A study of the effect of seasonal climatic factors on the electrical resistivity response of three experimental graves

    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.

    We experienced a coincidental case of two types of glomerulopathy associated with Graves' disease. A 64-year-old man, who had been treated with propylthiouracil(PTU) for Graves' disease for 15 years, was admitted to our hospital for macroscopic hematuria and rapidly progressive deterioration of renal function. Although his thyroid function had been within the normal range during treatment, the level of thyrotropin receptor antibody(TRAb) gradually increased from a year before admission. Serological tests revealed that he was positive for myeloperoxidase-antineutrophil cytoplasmic antibody(MPO-ANCA). The renal biopsy specimen showed necrotizing and crescentic glomerulonephritis(GN) superimposed on membranous nephropathy(MN). This is a rare case of MN complicated with ANCA associated crescentic GN in a Graves' disease patient. Association of these two renal alterations was not clearly defined. MN involved with Graves' disease also has been rarely reported. Some reports demonstrated deposition of thyroglobulin and other thyroid related antigens in the glomeruli. In the present case, long-term impairment of Graves' disease and elevation of TRAb might have been responsible for the formation and deposition of thyroid-associated immune complex in the glomeruli. As for crescentic GN, PTU might have induced ANCA-associated GN independently of MN. This case is instructive for considering the relation between Graves' disease and renal injury.

    Full Text Available OBJETIVO: Estimar a prevalência da morbidade materna extremamente grave e identificar procedimentos hospitalares associados. MÉTODOS: Foram utilizados dados do Sistema de Informação Hospitalar fornecidos pela Secretaria de Saúde de Juiz de Fora, MG, de 2006 a 2007. Foram selecionadas as internações para procedimentos obstétricos (n = 8.620 mulheres cujo diagnóstico principal compreendia todo o capítulo XV, gravidez, parto e puerpério, da Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde, Décima Revisão. Foram identificados os códigos dos procedimentos realizados, procedimentos especiais e atos profissionais que pudessem contemplar o critério de morbidade materna extremamente grave da Organização Mundial da Saúde e outros procedimentos não habitualmente utilizados no período gravídico-puerperal. A análise de regressão logística foi utilizada para identificar associações entre desfecho e variáveis selecionadas. RESULTADOS: A prevalência de morbidade materna foi 37,8/1000 mulheres e a proporção de mortalidade foi 12/100.000 mulheres. O tempo de internação > 4 dias foi 13 vezes mais alto entre as mulheres que apresentaram alguma morbidade. Após análise ajustada, os fatores preditores de morbidade materna extremamente grave foram: tempo de internação, número de internações e filhos natimortos, e os procedimentos/condições mais frequentes foram a transfusão de hemoderivados (15,7/1.000, "permanência a maior" (9,5/1.000 e pré-eclâmpsia grave/eclâmpsia (8,2/1.000. CONCLUSÕES: Foi alta a prevalência de morbidade materna extremamente grave, associada principalmente às internações e variáveis relacionadas ao recém-nascido. O critério para identificação dos casos e o uso do Sistema de Informações Hospitalares mostraram-se úteis para a vigilância da morbimortalidade materna e para ampliar o conhecimento sobre os aspectos que a envolvem, contribuindo para a

    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.

  4. Discordant hypothyroxinemia and hypertriiodothyroninemia in treated patients with hyperthyroid Graves' disease

    1986-07-01

    Hypothyroxinemia and hypertriiodothyroninemia may occur in the course of antithyroid drug or /sup 131/I treatment for hyperthyroid Graves' disease. To determine the frequency of combined high serum T3 and low serum T4 concentrations during such treatment and to assess the clinical significance of its recognition, we reviewed 60 patients treated for hyperthyroid Graves' disease with antithyroid drugs (n = 43) or radioactive iodine (n = 17). Six of these patients (10%) were found to have high serum T3 and low serum T4 concentrations during therapy. Four were receiving antithyroid drugs, and 2 had received radioactive iodine. At the time this abnormality occurred, 4 patients were euthyroid, 1 was hypothyroid, and 1 was hyperthyroid. The serum TSH concentration was increased in 2, at the upper limit of normal in 1, and undetectable in 3 patients. After discontinuation or reduction in the dose of antithyroid drug, clinical and chemical euthyroidism was restored in 2 additional patients with previously elevated TSH levels. In 2 patients, both of whom previously had undetectable serum TSH levels, clinical hyperthyroidism persisted or recurred, and additional therapy was required. No patient developed permanent hypothyroidism during the period of follow-up (1-22 months). An additional 19 of the 60 patients (32%) had an elevated serum T3 level with a normal serum T4 concentration during the course of follow-up. Among the 19 patients, the magnitude of serum T3 elevation was not different between clinically euthyroid (n = 13) and hyperthyroid (n = 6) patients. We conclude that discordance of serum T4 and T3 concentrations is frequently encountered in patients with hyperthyroid Graves' disease during or after therapy. The low serum T4 level does not predict hypothyroidism, nor does a high serum T3 level predict hyperthyroidism.

    Full Text Available Pretibial myxedema is an uncommon manifestation of Graves' disease and because of its rarity, information regarding its natural course and its relationship with other manifestations of Graves' disease is not sufficient."nWe reviewed 150 consecutive cases diagnosed as having pretibial myxedema in a twenty-year period in a tertiary care center. Only one patient in this group did not have ophthalmopathy, and the majority of cases had significant proptosis and ophthalmopathy, 30% required orbital decompression surgery. Dermopathy is a late manifestation of the Graves' disease and its onset is usually after the diagnosis of hyperthyroidism and ophthalmopathy. In a few patients, dermopathy preceded diagnosis of hyperthyroidism or the onset of ophthalmopathy. Fourteen patients have never had hyperthyroid, eleven patients in this group had developed spontaneous hypothyroidism."nAll cases showed the involvement of the lower extremities, and only one patient showed to have combined upper and lower extremities involvement. The most common form of thyroid dermopathy was non-pitting edema. Nodular and plaque forms were also relatively common and occurred with equal frequency. Polypoid form occurred in one patient and elephantiatic form in another. There was no consistent correlation among different types of dermopathy and severity of eye disease."nDuring a three-month to nineteen-year follow up in 120 patients, complete remission was observed only in twelve patients. Partial remission was more common and occurred more frequently in patients who had local steroid therapy. it is possible that patients with remission might have been excluded of the follow up program.Thus, the remission data should be interpreted cautiously.

  6. Current perspectives on the role of orbital fibroblasts in the pathogenesis of Graves' ophthalmopathy.

    Graves' ophthalmopathy (GO) is an extra-thyroidal complication of Graves' disease (GD; Graves' hyperthyroidism) characterized by orbital tissue inflammation, expansion, remodeling and fibrosis. Although the initiating trigger of GO is still indistinct, excessive orbital fibroblast activity is at the heart of its pathogenesis. Orbital fibroblasts are activated by cellular interactions with immune cells and the soluble factors they secrete. Orbital fibroblasts, especially from GO patients, express the thyrotropin receptor (TSH-receptor; TSHR), and activation of the orbital fibroblast population by stimulatory autoantibodies directed against the TSHR may provide an important link between GD and GO. Furthermore, stimulatory autoantibodies directed against the insulin-like growth factor-1 receptor have been proposed to contribute to orbital fibroblast activation in GO. Activated orbital fibroblasts produce inflammatory mediators thereby contributing to the orbital inflammatory process in GO. Moreover, orbital fibroblasts exhibit robust proliferative activity and extracellular matrix (especially hyaluronan) synthesizing capacity and can differentiate into adipocytes and myofibroblasts with disease progression, thereby contributing to tissue expansion/remodeling and fibrosis in GO. Orbital fibroblasts, especially those from GO patients, exhibit a hyper-responsive phenotype when compared to fibroblasts from other anatomical regions, which may further contribute to GO pathogenesis. Fibrocytes have been identified as additional source of orbital fibroblasts in GO, where they may contribute to orbital tissue inflammation, adipogenesis and remodeling/fibrosis. This review addresses our current view on the role that orbital fibroblasts fulfill in GO pathogenesis and both established as well as less established not fully crystallized concepts that need future studies will be discussed.

    We studied the effects of radioiodine treatment of hyperthyroidism due to Graves' disease on Graves' ophthalmopathy and the possible protective role of corticosteroids. Between June 1985 and June 1988, 26 patients were randomly assigned to treatment with radioiodine alone (group 1) and 26 to treatment with this agent and concomitant administration of systemic prednisone for four months (group 2). The initial dose of prednisone was 0.4 to 0.5 mg per kilogram of body weight for one month; the drug was gradually withdrawn over the next three months. All patients were evaluated at 3-month intervals for 18 months after they underwent radioiodine therapy. Ocular changes were assessed with the ophthalmopathy index; patients with moderate-to-severe changes (scores greater than or equal to 4) were excluded from the study. Before treatment, 10 patients in group 1 and 5 in group 2 had no evidence of ophthalmopathy: in none of them did ocular symptoms appear after radioiodine therapy. Among the patients in group 1 with an initial ophthalmopathy index greater than or equal to 1, ocular disease worsened in 56 percent (mostly involving soft-tissue changes and extraocular-muscle function) and did not change in 44 percent. In contrast, ophthalmopathy improved in 52 percent and did not change in 48 percent of group 2. The mean ophthalmopathy index increased from 1.5 to 3.0 in group 1 (P less than 0.005) and decreased from 2.2 to 1.3 in group 2 (P less than 0.05). We conclude that systemic corticosteroid treatment prevents the exacerbations of Graves' ophthalmopathy that occur after radioiodine therapy in a substantial proportion of patients with hyperthyroidism who have some degree of ocular involvement before treatment.

    2016-02-01

    Full Text Available CONTEXT Acute surgical pathology may be overlooked in pregnancy. Despite advances in medical technology, preoperative diagnosis of potentially grave pathologies of the gastrointestinal tract (GIT is often delayed due to overlap with symptoms of pregnancy non-specific elevation of some laboratory parameters due to pregnancy and a dilemma for obstetricians and surgeons in ordering radiological imaging modalities given the risk associated with fetal exposure to ionizing radiation and contrast. AIMS The aim of this study is to analyse the cases of gastrointestinal tract problems encountered in pregnancy so that increasing awareness can be created among obstetricians. This is important because early diagnosis and timely intervention can significantly improve maternal and fetal outcome in these cases. SETTINGS AND DESIGN There is a retrospective case study of potentially grave GIT problems encountered at Vanivilas hospital, Bangalore, a tertiary referral institute wherein the clinical presentation was confounded by pregnancy. MATERIALS AND METHODS All the included cases were analysed for age of the patient, pre-existing gastrointestinal tract disorders, gestational age at diagnosis, maternal and fetal outcome. RESULTS A total of 8 cases of GIT problems in pregnancy were studied. Though acute appendicitis is the most common cause of GIT emergency in pregnancy as quoted in literature 5, we did not encounter any case of acute appendicitis in pregnancy in the study period. Other conditions which were encountered were small bowel obstruction, stomach and bowel perforation and bleeding oesophageal varices. Whilst few of the conditions could be managed conservatively without harm to the pregnancy, others required a laparotomy and reparative procedures. Delay in diagnosis and intervention proved to be fatal in some of these women. CONCLUSIONS Knowledge about potentially grave gastrointestinal tract problems during pregnancy, high index of clinical suspicion

    Graves' disease (GD) is a common autoimmune disease (AID) that shares many of its susceptibility loci with other AIDs. The thyroid stimulating hormone receptor (TSHR) represents the primary autoantigen in GD, in which autoantibodies bind to the receptor and mimic its ligand, thyroid stimulating...... hormone, causing the characteristic clinical phenotype. Although early studies investigating the TSHR and GD proved inconclusive, more recently we provided convincing evidence for association of the TSHR region with disease. In the current study, we investigated a combined panel of 98 SNPs, including 70...

    Splenic abscesses are increasingly being identified, possibly due to widespread use of imaging modalities in clinical practice. The commonest clinical features are high grade fever and exclusively localised left upper quadrant abdominal pain. These symptoms are similar to most infectious diseases prevalent in the tropics, making imaging by ultrasonography or computer tomography a necessity in the diagnosis. There are reports from different geographic areas on splenic abscesses associated with typhoid fever. We reported ruptured splenic abscess presenting with peritonitis as a rare and grave complication of typhoid fever.

    Full Text Available Abstract I developed Graves' Disease four months postpartum. After one year on propylthiouracil, I learned that omega-3 fatty acids may reduce inflammation associated with certain autoimmune disorders, although no investigations for thyroiditis have been reported. Within eight weeks of beginning flaxseed oil supplements, TSH levels normalized, but fell somewhat when flaxseed was decreased and PTU discontinued. During another pregnancy, plasma TSH normalized, but was again suppressed by four weeks postpartum, then undetectable by four months. This time, flaxseed supplementation alone coincided with TSH normalization. Omega-3 fatty acids should be investigated as a potential treatment for autoimmune thyroid disease.

    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

    Graves' disease and Hashimoto's thyroiditis are common autoimmune thyroid disorders. Experimentally, 1,25(OH)(2) D(3) prevents Hashimoto's thyroiditis. Vitamin D serum levels in Graves' disease were found to be significantly lower than in nonautoimmune hyperthyroidism. The polymorphic vitamin D-binding protein (DBP) greatly facilitates vitamin D actions, and DBP alleles differ regarding their affinity for 1,25(OH)(2) D(3). Therefore, we investigated polymorphisms of the DBP gene for an association with thyroid autoimmunity. Families with an offspring affected by Graves' disease (95 pedigrees) or by Hashimoto's thyroiditis (92 pedigrees) encompassing 561 individuals of Caucasian origin were genotyped for three DBP polymorphisms [(TAAA)(N) in intron 8; StyI; and HaeIII in exon 11]. Indirect haplotyping and (extended) transmission disequilibrium testing were performed. There was a significant transmission disequilibrium of the intron 8 polymorphism in patients with Graves' disease (P < 0.03) but not of the exon 11 polymorphism. In contrast, neither the intron 8 nor the exon 11 polymorphism was associated with Hashimoto's thyroiditis. Maternal and paternal transmission as well as allele frequencies in DQ2(+) and DQ2(-) patients did not differ in either disease. Therefore, allelic variants of the DBP gene confer susceptibility to Graves' disease but not to Hashimoto's thyroiditis in our population. These findings support a role of the vitamin D endocrine system in thyroid autoimmunity.

    In the context of the preliminary study phase for the CubeSats supporting ESA's Asteroid Impact Mission (AIM) to the Didymos, we investigate a miniaturized gravimeter as part of the geophysical instrument package for the Asteroid Geophysical Explorer (AGEX). AGEX intends to land a CubeSat on the secondary object in the Didymos system, Didymoon in order to characterize the asteroid surface and internal structure A 3D compact gravimeter is developed at the Royal Observatory of Belgium. Its design allows to meter a weak 50 μm/sec² gravity field corresponding to 5 ppm of Earth gravity in a harsh environment. A system with three components mounted in an orthogonal geometry allows obtaining the gravity field in amplitude and in angular position without any requirement of levelling. B-GRAVES will use a in-situ calibration and multi-parameter approach for validation of the measurements. A laboratory simulation is induced with centrifugal forces applied to the pendulum set-up in a vertical position to reject the Earth gravity field. Signal treatment and uncertainties are discussed keeping in mind questions of thermal and vibration influence. The B-GRAVES can serve as a novel and robust instrument for future lander and rover missions .

  14. Association between age at diagnosis of Graves' disease and variants in genes involved in immune response.

    Beata Jurecka-Lubieniecka

    Full Text Available BACKGROUND: Graves' disease (GD is a complex disease in which genetic predisposition is modified by environmental factors. The aim of the study was to examine the association between genetic variants in genes encoding proteins involved in immune response and the age at diagnosis of GD. METHODS: 735 GD patients and 1216 healthy controls from Poland were included into the study. Eight genetic variants in the HLA-DRB1, TNF, CTLA4, CD40, NFKb, PTPN22, IL4 and IL10 genes were genotyped. Patients were stratified by the age at diagnosis of GD and the association with genotype was analysed. RESULTS: Polymorphism in the HLA-DRB1, TNF and CTLA4 genes were associated with GD. The carriers of the HLA DRB1*03 allele were more frequent in patients with age at GD diagnosis ≤30 years than in patients with older age at GD diagnosis. CONCLUSIONS: HLADRB1*03 allele is associated with young age at diagnosis of Graves' disease in Polish population.

    Full Text Available Foi feita avaliação dos resultados da timectomia transtorácica em 73 pacientes com miastenia grave generalizada, sendo 64 não timomatosos e 9 com timomas. Os resultados foram analisados à curto, médio e, em muitos casos, a longo prazo. Foi feito, também um estudo comparativo dos resultados em relação à idade, sexo, tempo de doença e à presença ou não do timoma. A experiência adquirida neste grupo de pacientes sugere que a timectomia transtorácica é método terapêutico útil na miastenia grave generalizada não timomatosa; seu efeito benéfico aparece no pós-operatório mediato e se mantém a longo prazo na maioria dos pacientes. Os resultados da timectomia em pacientes com timoma foram menos favoráveis. A análise estatística não mostrou diferenças significantes na evolução pós-operatória entre os pacientes não timomatos selecionados e não selecionados.

Estes três grupos foram comparados quanto a idade, idade de início dos sintomas, tempo de doença, formas clinicas, escala funcional e intensidade dos sintomas, seguidos durante vários anos, estudando-se o número de remissões, melhora, estabilidade ou piora dos sintomas e número de óbitos. Somente tiveram melhora dos sintomas (p<0,05 os timectomizados do grupo 1; os demais parâmetros de todos os grupos não se mostraram estatisticamente significativos. Esses resultados sugerem que o tipo de tratamento pouco interferiu na evolução da miastenia grave neste grupo de pacientes.

    Full Text Available Fundamentados no fato de que, tanto na literatura nacional quanto na estrangeira, inexiste referência da associação de polimiosite, miastenia grave e timoma em adulto jovem do sexo masculino, os autores se propõem a descrever um caso da citada síndrome. O paciente aqui apresentado teve sua doença iniciada aos 22 anos de idade, atingindo sua expressão clínica máxima 4 anos miais tarde. No estudo em apreço, são enfatizadas as dificuldades no diagnóstico diferencial entre polimiosite e miastenia grave, doenças que, a principio, têm suas manifestações clinicas características, de modo geral bem individualizadas. Na presente observação chamamos a atenção para a possível existência de aspectos clínicos sugestivos de miastenia em enfermos com polimiosite e, por outro lado, alterações histopatológicas típicas de polimiosite em músculos de miastênicos, inviabilizando muitas vezes o diagnóstico clínico de certeza.

    Full Text Available Objective. Graves' disease is the most common cause of hyperthyroidism in the pediatric population. Antithyroid medications used in children and adults include propylthiouracil (PTU and methimazole (MMI. At our center we have routinely used MMI for Graves' disease therapy. Our goals are to provide insights into adverse events that can be associated with MMI use. Methods. We reviewed the adverse events associated with MMI use in our last one hundred consecutive pediatric patients treated with this medication. Results. The range in the patient age was 3.5 to 18 years. The patients were treated with an average daily dose of MMI of 0.3±0.2 mg/kg/day. Adverse events attributed to the use of the medication were seen in 19 patients at 17±7 weeks of therapy. The most common side effects included pruritus and hives, which were seen in 8 patients. Three patients developed diffuse arthralgia and joint pain. Two patients developed neutropenia. Three patients developed Stevens-Johnson syndrome, requiring hospitalization in 1 child. Cholestatic jaundice was observed in 1 patient. No specific risk-factors for the development of adverse events were identified. Conclusions. MMI use in children is associated with a low but real risk of minor and major side effects.

    2013-03-01

    Full Text Available Evidências recentes sugerem que o balanço proteico negativo secundário à doença grave se associa ao aumento de morbidade. A perda da proteína corporal total é inevitável nesse cenário, mesmo com uma abordagem nutricional agressiva, e resulta, principalmente, do catabolismo da fibra muscular esquelética. O principal mecanismo bioquímico e metabólico envolvido nesse processo é o sistema ubiquitina-proteassoma, que, paradoxalmente, consome a adenosina trifosfatocomo fonte energética e motriz. É possível que a neutralidade do balanço proteico nessas instâncias clínicas, seja tão importante na melhora dos desfechos quanto atingir a meta calórica estimada ou medida pela calorimetria indireta. Estudos recentes apontam a utilização de concentrações mais elevadas de proteínas na terapia nutricional do paciente grave como importante para um impacto positivo na mortalidade. A proposta deste trabalho foi revisar alguns princípios da terapia nutricional relativos ao metabolismo proteico, sinalizar para as principais assertivas das diretrizes das sociedades especializadas e comentar estudos recentes, que abordam a questão em tela, sob a visão crítica da experiência clínica dos autores.

Results The study showed significantly (p Conclusion The results indicated a clinically relevant impact of thyroid function on bone modulation also in premenopausal women with Graves' disease, and further indicated the possibility for a direct action of TRAb on bones.

  3. Transient Hypothyroidism after Radioiodine for Graves' Disease: Challenges in Interpreting Thyroid Function Tests.

    2016-03-01

    Graves' disease is the most common cause of hyperthyroidism and is often managed with radioactive iodine (RAI) therapy. With current dosing schemes, the vast majority of patients develop permanent post-RAI hypothyroidism and are placed on life-long levothyroxine therapy. This hypothyroidism typically occurs within the first 3 to 6 months after RAI therapy is administered. Indeed, patients are typically told to expect life-long thyroid hormone replacement therapy to be required within this timeframe and many providers expect this post-RAI hypothyroidism to be complete and permanent. There is, however, a small subset of patients in whom a transient post-RAI hypothyroidism develops which, initially, presents exactly as the typical permanent hypothyroidism. In some cases the transient hypothyroidism leads to a period of euthyroidism of variable duration eventually progressing to permanent hypothyroidism. In others, persistent hyperthyroidism requires a second dose of RAI. Failure to appreciate and recognize the possibility of transient post-RAI hypothyroidism can delay optimal and appropriate treatment of the patient. We herein describe five cases of transient post-RAI hypothyroidism which highlight this unusual sequence of events. Increased awareness of this possible outcome after RAI for Graves' disease will help in the timely management of patients.

    Full Text Available According to the EUGOGO’s (European Group On Graves' Orbitopathy last consensus, the treatment of choice for Graves’ Orbitopathy (GO is pulses of glucocorticoid (GC. There is a lack of evidence for superiority of any intravenous (iv GC schedules. As a rule this therapy is pretty safe. However, acute cardiovascular diseases and acute severe liver damage has been reported in sporadic cases during ivGC, resulting in fatal acute liver failure in a few patients. Design: we performed a prospective study in 36 Graves' patients with GO who were treated with 1000 mg of ivGC daily for 5 days (group I, n = 20 or weekly for 5 weeks (group II, n = 16. Results: ALAT and ASAT increases were much more prominent in group I than in group II especially during the treatment and in the first 4 weeks after the treatment. Increase of blood pressure, glycemia and negative ECG alterations in group I resulted to their management. And we revealed much more patients complains in group I. Conclusion: Both schedules seem to be pretty safe, but therapy once a week (for 5 weeks is safer and allows to treat patients in outpatient clinics, reduce expenditures on inpatient care, accelerate of initial treatment and include more patients into treatment.

    Background: Graves' ophthalmopathy (GO) occurs commonly in children with Graves' disease (GD). However, there are limited studies on the clinical manifestations and thyroid autoantibodies in pediatric GO. The aim of this study was to investigate the prevalence and risk factors of GO in childhood GD. Methods: Clinical and biochemical data from children and adolescents with GD were retrospectively reviewed. Eighty patients under 19 years of age were included in the present study. We compared the clinical and biochemical differences between patients with and without GO. Results: Thirty-nine percent of the patients had GO, and 81% of the GO patients were females. Of these, two patients showed unilateral GO. Triiodothyronine (T3) levels were higher in GO patients than in those without GO. Anti-thyroglobulin antibody and thyroid stimulating hormone receptor antibody titers were not significantly different between the two groups. Anti-thyroid peroxidase antibody (TPO Ab) positivity was 68% in the patients with GO and only 47% in the patients without GO. In multivariate regression analysis, high T3 levels and TPO Ab positivity were related to the presence of GO. Conclusion: In children and adolescents with GD, TPO Ab positivity and high T3 levels could act as predictive factors for the presence of GO.

    Adipocytokines are thought to be associated with inflammatory disorders and autoimmune diseases. However, limited information is available on the relationship between serum adipocytokine levels, Graves' disease (GD), and Graves' ophthalmopathy (GO). The present study examined the relationship between serum adipocytokine levels and GD and GO. A total of 80 patients with GD participated in this study. The medical records of patients were reviewed retrospectively. GO activity was assessed using the clinical activity score (CAS). GO severity was assessed by the modified NOSPECS classification and included soft tissue involvement, proptosis, and extraocular muscle involvement. Serum adiponectin, leptin, resistin, and retinol-binding protein 4 (RBP-4) levels were measured using commercially available enzyme-linked immunosorbent assays. The prevalence of GO was 36.3%. Serum adiponectin, leptin, and resistin levels were significantly higher in patients with GO than in those without GO. The CAS was positively correlated with serum adiponectin and leptin levels. The total eye score was positively correlated with serum adiponectin, leptin, resistin, and RBP-4 levels. A multivariate analysis revealed that serum leptin and resistin levels were associated with the presence of GO after adjusting for clinical factors. Free thyroxine was negatively correlated with serum leptin level. These results suggest that adipocytokines, such as leptin and resistin, may play a role in inflammatory and autoimmune processes of GD and GO. Future studies with larger numbers of patients are required to establish relationships between serum adipocytokines levels and GO and ascertain the role of adipocytokines in GD and GO.

    Purpose: To evaluate the clinical and radiologic response of patients with Graves' ophthalmopathy given low-dose orbital radiotherapy (RT) with a protracted fractionation. Methods and Materials: Eighteen patients (36 orbits) received orbital RT with a total dose of 10 Gy, fractionated in 1 Gy once a week over 10 weeks. Of these, 9 patients received steroid therapy as well. Patients were evaluated clinically and radiologically at 6 months after treatment. Clinical response assessment was carried out using three criteria: by physical examination, by a modified clinical activity score, and by a verbal questionnaire considering the 10 most common signs and symptoms of the disease. Radiologic response was assessed by magnetic resonance imaging. Results: Improvement in ocular pain, palpebral edema, visual acuity, and ocular motility was observed in all patients. Significant decrease in symptoms such as tearing (p < 0.001) diplopia (p = 0.008), conjunctival hyperemia (p = 0.002), and ocular grittiness (p = 0.031) also occurred. Magnetic resonance imaging showed decrease in ocular muscle thickness and in the intensity of the T2 sequence signal in the majority of patients. Treatments were well tolerated, and to date no complications from treatment have been observed. There was no statistical difference in clinical and radiologic response between patients receiving RT alone and those receiving RT plus steroid therapy. Conclusion: RT delivered in at a low dose and in a protracted scheme should be considered as a useful therapeutic option for patients with Graves' ophthalmopathy.

RELATO DOS CASOS: O primeiro é uma paciente de 22 anos de idade com quadro súbito de disartria e déficit motor em dimídio esquerdo. Ao exame clínico, apresentava taquicardia, exoftalmia bilateral e bócio difuso. Referia tratamento para hipertiroidismo há um mês. O segundo é uma paciente de 15 anos de idade, que apresentou quadro súbito de perda da consciência seguindo-se distúrbio de linguagem e déficit motor em hemicorpo direito. RESULTADOS: Os exames de imagem revelaram áreas de lesão cerebral sugestivas de isquemia. Os estudos angiográficos cerebrais evidenciaram estenoses vasculares múltiplas compatíveis com arterite. Foram descartadas outras causas possíveis de vasculite cerebral. Os exames laboratoriais revelaram hipertiroidismo e presença dos anticorpos antimicrossomais e antitireoglobulina. As duas pacientes receberam tratamento para o hipertiroidismo. CONCLUSÃO: A associação entre arterite cerebral e doença de Basedow-Graves sugere que possa existir um elo na patogenia das duas doenças através de mecanismo auto-imune comum a ambas.

  12. Imaging studies for diagnosing Graves' orbitopathy and dysthyroid optic neuropathy

    Allan C. Pieroni Gonçalves

    2012-11-01

    Full Text Available Although the diagnosis of Graves' orbitopathy is primarily made clinically based on laboratory tests indicative of thyroid dysfunction and autoimmunity, imaging studies, such as computed tomography, magnetic resonance imaging, ultrasound and color Doppler imaging, play an important role both in the diagnosis and follow-up after clinical or surgical treatment of the disease. Imaging studies can be used to evaluate morphological abnormalities of the orbital structures during the diagnostic workup when a differential diagnosis versus other orbital diseases is needed. Imaging may also be useful to distinguish the inflammatory early stage from the inactive stage of the disease. Finally, imaging studies can be of great help in identifying patients prone to develop dysthyroid optic neuropathy and therefore enabling the timely diagnosis and treatment of the condition, avoiding permanent visual loss.

    We report a case of a 60-year-old lady who presented with bilateral lower limb swelling and a thyroid swelling with clinical features consistent with thyrotoxicosis. Investigations revealed the presence of a thrombus in bilateral external, internal iliac veins, and inferior vena cava extending up to its infrahepatic part. Hormone profile and radioiodine uptake scan confirmed the diagnosis of Graves' disease. Further workup revealed the presence of antiphospholipid antibodies (confirmed after a repeat test at 12 weeks). The patient was treated with antithyroid drugs and anticoagulants. The patient improved with normalization of thyroid function and partial recanalization of the infrahepatic part of inferior vena cava. Hyperthyroidism has been implicated as a potential hypercoagulable state; however, the association of Graves' disease with antiphospholipid antibody syndrome is limited to isolated case reports. This case highlights a new mechanism underlying hypercoagulability associated with Graves' disease.

    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{sub 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{sub 3} suppression test, this rapid and simple method seemed suitable for routine use in clinical practice.

Colombia, por la diversidad de climas y condiciones variadas de suelos, está capacitada para producir ventajosamente las especies frutales que en general son consideradas como de carácter comercial. Entre las cuales, el aguacate, dentro de la zona tropical y subtropical, ocupa lugar prominente, junto con el popular grupo de los Citrus. Aunque la explotación de estas especies frutales se encuentra en forma incipiente, y para mejor decirlo en estado semisilvestre, la correcta vegetación y fructificación abundante lograda dentro de vastas zonas, son un elocuente índice, que unido a la demanda creciente de fruta en los mercados, insatisfecha con la escasa producción nacional, aseguran el éxito de las empresas que consagren sus esfuerzos a la lucrativa industria de la producción de frutas. 2.

L'objectif de cette étude est d'analyser certains facteurs favorisants et d’évaluer les critères de gravité en fonction des formes anatomo-cliniques. Il s'agit d'une étude rétrospective réalisée, entre janvier 2007 et décembre 2012, au service de chirurgie maxillo faciale de l'hôpital militaire Avicenne de Marrakech. Sur 147 cas de cellulites cervico-faciales pris en charge au niveau du service, 13 dossiers de cellulites graves ont été retenus. Neuf hommes (69%) et quatre femmes (31%) ont fait l'objet de cette étude, avec un âge moyen de 35 ans. Tous les patients ont été adressés pour prise en charge secondaire après avoir pris des anti-inflammatoires (AI). Sept cas (54%) étaient immunocompétents. La cause dentaire était soulevée chez neufs cas (69%). Cinq cas (38%) ont présenté une forme pseudo phlegmoneuse avec des signes compressifs des voies aéro-digestives. L'extension médiastinale a été observée chez quatre patients (31%). La forme nécrosante extensive a été retrouvée dans trois cas (23%). L’étude bactériologique, réalisée chez tous les patients, avait mis en évidence une flore microbienne mixte et polymorphe. Les cellulites cervico-faciales graves posent un réel problème de prise en charge thérapeutique. L'analyse des facteurs favorisants et l’évaluation des critères de gravité dans cette série ont permis de limiter une évolution défavorable. PMID:26113891

    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; (ii) 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

    Full Text Available La nutrición enteral se ha demostrado como un método eficaz y seguro de nutrir a los enfermos graves ingresados en una Unidad de Cuidados Intensivos. Aunque se desconoce cuánto tiempo puede estar un enfermo grave sin nutrición, el catabolismo acelerado y el ayuno pueden ser deletéreos en el enfermo grave y la recomendación más frecuente es la de empezar la nutrición artificial cuando se prevea un período de ayuno superior a los siete días. Las ventajas de la nutrición enteral sobre la nutrición parenteral son evidentes a nivel experimental inmune tanto local como sistémica y mantiene las funciones de barrera del intestino. Estudios clínicos han demostrado que la nutrición enteral precoz, administrada en las primeras 48 horas de ingreso, disminuye la incidencia de infecciones nosocomiales en estos enfermos aunque no la mortalidad, salvo en grupos concretos de pacientes, especialmente en enfermos quirúrgicos. El mayor inconveniente de la nutrición enteral es su intolerancia digestiva y el abordaje trans-pilórico, necesario cuando se produce gastroparesia. También existen dudas de su eficacia cuando el enfermo está en situación de isquemia tisular. Para que la nutrición enteral precoz sea eficaz hace falta instaurar una estrategia terapéutica que incluye tanto medidas sencillas como la elevación del cabecero de la cama, a medidas más sofisticadas como el abordaje trans-pilórico o el uso de nutrientes con capacidad inmunomoduladora. El uso de nutrición enteral precoz es, hoy por hoy, el mejor método de soporte nutricional en estos enfermos si se individualiza su uso en función de la situación clínica de cada paciente y se realiza mediante una estrategia terapéutica adecuada.

    In the present work we show a forensic case study carried out in a mountainous environment. Main objective was to locate a clandestine grave which is around 10-20 years old and contains human remains of one individual and a metallic tool, probably a pick. Survey design started with an experimental burial of a pick at the expected depth (1m) as well as the calculation of synthetic radargrams in order to know if the 250MHz antenna was suitable for its detection and to have a record of the reflection of the pick. Conclusions extracted from the experiments together with rough terrain conditions suggested the use of the 250MHz antenna which allowed a good compromise between target detection and dense grid acquisition of an extensive survey area.

    Hazardous materials management includes interactions among materials, personnel, facilities, hazards, and processes of various groups within a DOE site`s environmental, safety & health (ES&H) and line organizations. Although each group is charged with addressing a particular aspect of these properties and interactions, the information it requires must be gathered into a coherent set of common data for accurate and consistent hazardous material management and regulatory reporting. It is these common data requirements which the Cradle-to-Grave Tracking and Information System (CGTIS) is designed to satisfy. CGTIS collects information at the point at which a process begins or a material enters a facility, and maintains that information, for hazards management and regulatory reporting, throughout the entire life-cycle by providing direct on-line links to a site`s multitude of data bases to bring information together into one common data model.

    Palpable purpura is a concerning clinical finding in pediatric patients and can have many causes, including infectious and autoimmune processes. A rare cause, drug-induced vasculitis, may result from the production of antineutrophil cytoplasmic antibodies (ANCAs) in response to a medication. We report a girl with Turner syndrome and Graves' disease who presented with palpable purpuric lesions. The diagnosis of propylthiouracil (PTU)-associated vasculitis was made by observation of consistent clinical features, the detection of elevated ANA and ANCA in the blood, and the observed clinical resolution of symptoms following withdrawal of PTU. Subsequent treatment of persistent hyperthyroidism with radioablation did not result in an exacerbation of the vasculitis, a complication described in prior case reports.

    Radioactive iodine therapy using I-131 for hyperthyroidism has been used for more than 50 years, and generally considered safe and devoid of major side effects. Appropriate patient selection criteria and clinical judgement concerning patient preparation should be employed for its optimal use. It has not been possible to resolve the trade-off between efficient definite cure of hyperthyroidism and the high incidence of post-therapy hypothyroidism. The dose of the I-131 needed to maintain euthyroid state remains an area of uncertainty and debate. Early side effects are uncommon and readily manageable. Other than the need for long-term monitoring and, in most cases, lifelong thyroid hormone treatment for late adverse consequences of this treatment remains only conjectural. We have reviewed general principles and recent advances in radioiodine treatment for Graves' hyperthyroidism, specially regarding to several controversies.

    To compare the dosimetry of tomotherapy and the conventional half-beam technique (HBT) or non-split beam technique (NSBT) for target coverage and radiation dose to the lacrimal glands and lens. A retrospective review of 7 patients with Graves' ophthalmopathy who had radiotherapy because of disease progression on high steroid dose is reported: 3 patients were treated with tomotherapy and 4 patients with HBT. Compared to HBT, tomotherapy may provide better target coverage and significant reduction of radiation dose to the lacrimal glands and a higher dose to the lens. The NSBT improved target coverage but resulted in significantly higher doses to the lens and lacrimal glands. Tomotherapy may provide better coverage of the target volume and may be more effective in reducing severe exophthalmos compared to the conventional radiotherapy technique. (orig.)

    This study evaluated the prevalence and severity of ophthalmic manifestations in all Graves disease patients (n = 68) presenting to endocrine clinics at Mashad University of Medical Sciences between December 2002 and September 2005. The mean age of patients was 38.0 (SD 14.0) years, range 15 to 71 years. The most common complaints were foreign body sensation (54.0%) and puffy eyelids (48.4%). The most common apparent abnormality was lid retraction in 64.2% of patients (bilateral in 95.3% of cases). The patients had a mean modified Werner's NO SPECS classification score of 3.00 (SD 1.46). The score was significantly higher in males than females [3.58 (SD 1.44) versus 2.63 (SD 1.35)] and was positively correlated with age.

    A hallmark of regulatory B cells is IL-10 production, hence their designation as IL-10+ B cells. Little is known about the ability of self-antigens to induce IL-10+ B cells in Graves' disease (GD), Hashimoto's thyroiditis (HT), or other autoimmune disease. Here we pulsed purified B cells from 12 HT...... patients, 12 GD patients, and 12 healthy donors with the thyroid self-antigen, thyroglobulin (TG) and added the B cells back to the remaining peripheral blood mononuclear cells (PBMCs). This procedure induced IL-10+ B-cell differentiation in GD. A similar tendency was observed in healthy donors......, but not in cells from patients with HT. In GD, B cells primed with TG induced IL-10-producing CD4+ T cells. To assess the maximal frequency of inducible IL-10+ B cells in the three donor groups PBMCs were stimulated with PMA/ionomycin. The resulting IL-10+ B-cell frequency was similar in the three groups...

Se realizó un estudio prospectivo, observacional, longitudinal, en 80 pacientes sépticos graves en el lapso de 1 año para determinar el desarrollo de injuria renal aguda y su relación con la mortalidad; correlacionar antecedentes clínicos y variaciones del laboratorio con la mortalidad; determinar la tasa de mortalidad de la sepsis grave; relacionar óbito y foco séptico primario; evaluar la predictibilidad de mortalidad según niveles de creatinina de ingreso y sus variaciones finales. Se definieron dos grupos: Obito (n = 25 y No-óbito (n = 55. Analizados según la creatinina de ingreso, 39 tenían valores normales de creatinina (10 óbitos y 41 la presentaban elevada (15 óbitos; según la creatinina de egreso, 48 presentaron creatinina normal y fallecieron 7, mientras que 32 tenían daño renal agudo, de los cuales 18 fallecieron. De los 25 pacientes fallecidos, el 72% presentaron daño renal. De éstos, 7 pacientes vivos y 2 fallecidos requirieron hemodiálisis. El foco primario más frecuente fue el respiratorio (26.4%. El desarrollo de daño renal es un alto predictor de mortalidad en la sepsis, independientemente de los valores iniciales de creatinina. Edad más avanzada, hipertensión arterial, score APACHE más elevado, anemia más grave, hipoalbuminemia, hiperfosfatemia e hiperkalemia se asociaron a mayor mortalidad. La mortalidad global fue 31.3%. La imposibilidad de identificar el foco séptico primario se asoció a mayor mortalidad.

    Full Text Available It has been found during the research that the changes of Th1 and Th2 marker cytokine content in Graves Disease are dynamic and are directly correlated not only with the severity of autoimmune thyrotoxicosis, but also with the method of treatment used and duration of Thiamazole therapy. The beginning of autoimmune thyrotoxicosis shows the largest amounts of both pro-inflammatory (IL-1a, IL-8, IFN-γ and anti-inflammatory (IL-10 cytokines which are significantly reduced during Thiamazole therapy, with the exception of the cases of severe disease course. Thyroid resection does not result in immunologic remission either, which is confirmed by persisting high serum levels of IL-1a, IL-8, IFN-γ, IL-10 and TSH antibodies in the severe GBD group. Among the unfavorable prognostic factors for recurrent disease are high serum levels of TSH antibodies, IL-1a and IFN-γ during pre-surgery period.

    Interferon-induced thyroiditis (IIT) is a major clinical problem for patients receiving interferon-alpha (IFN-α) therapy. But, destructive thyroiditis followed by Graves' disease associated with IFN-α therapy is very rarely reported. Herein, we report a rare case of pegylated IFN-α (pegIFN-α) induced destructive thyroiditis followed by Graves' disease in a patient with HCV infection. A 31-yr-old woman suffered from chronic active hepatitis C and was treated with pegIFN-α and ribavirin for 12 months. Results of a thyroid function test and autoantibody levels were normal before IFN-α therapy was initiated. Destructive thyrotoxicosis appeared seven months after the initiation of IFN-α therapy, followed by Graves' thyrotoxicosis two months after the cessation of therapy. The diagnoses of destructive thyroiditis and Graves' disease were confirmed by the presence of TSH receptor antibodies in addition to Tc-99m scintigraphy findings. The patient's antithyroglobulin antibody titer increased gradually during IFN-α therapy and remained weakly positive after IFN-α therapy was discontinued.

    Objective To explore the roles of Fcγ receptor in the pathogenesis of Graves' disease. Methods Fcγ receptor gene knockout mice(Fcγ R KO mice) which were rooted in C57BL/6 mice and wild type C57BL/6 mice were immunized by hTSH receptor expressing cells (DAP3.WT).1-2×107 DAP3.WT cells were peritoneally injected into mice every two weeks for a total of six times.Two weeks after final immunization, mice were killed for measurement of total thyroxine,TRAb and pathological examination.Results The thyroxine level of the immunized Fcγ receptor gene knockout mice was significantly lower than that of the immunized wild type control mice (2.2±0.31 vs.3.32±0.59g·dL-1,P<0.05), but there was no significant difference between immunized Fcγ R KO mice and non-immunized wild type control group.The TRAb levels of the immunized Fγ R KO mice significantly increased compared to those of the immunized wild type mice (21.75±8.21 vs.14.11±6.21, P<0.05). The lymphocyte cells infiltration and destruction of thyroid follicles were found in the thyroid gland of the immunized Fcγ R KO mice. Conclusion These results suggest that Fcγ receptor may be involved in the pathogenesis of Graves'disease.

    Full Text Available PURPOSE: To evaluate the efficacy of radiotherapy (RT with total dose of 20 Gy (RT 20 Gy in the treatment of Graves' ophthalmopathy. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical treatments for Graves' ophthalmopathy. The MEDLINE, EMBASE, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. RESULTS: A total of 8 randomized controlled trials (439 patients were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85-250, p=0.04, RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.59-6.23, p=0.003 and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, p=0.01. There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. CONCLUSION: Our data have shown that RT 20 Gy should be offered as a valid therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs.

    Full Text Available Severe acute pancreatitis is associated with a systemic inflammatory response leading to a hypermetabolic, hypercatabolic condition; for those reasons, patients suffering from this disease require an excellent artificial nutritional support in order to maintain the structural integrity and the function of vital organs with minimal pancreatic secretion. Total parenteral nutrition has been the standard practice in the treatment of patients with severe acute pancreatitis because of the favorable outcomes of early nutritional support while avoiding pancreatic stimulation; however, recent evidence suggests there are potentially greater benefits with enteral as compared with parenteral nutrition, including fewer septic and metabolic complications and lesser costs. That is why present guidelines for the management of acute pancreatitis recommend that enteral instead of parenteral nutrition be used in patients with severe acute pancreatitis. La pancreatitis aguda, especialmente en su forma grave, está asociada con una respuesta inflamatoria sistémica que lleva a un estado de hipermetabolismo e hipercatabolismo, en el que se requiere un excelente soporte nutricional que permita mantener la integridad estructural y la función de los órganos vitales con un estímulo mínimo de la secreción pancreática. La nutrición parenteral total era el soporte de elección, que permitía obtener todos los beneficios de la nutrición temprana sin estimular la secreción pancreática; pero la evidencia actual muestra mayores beneficios con la nutrición enteral, porque se asocia con menos complicaciones infecciosas y metabólicas y con disminución en los costos. Por ello las guías actuales de tratamiento de la pancreatitis aguda grave recomiendan como primera elección el soporte nutricional enteral.

    Full Text Available A pancreatite aguda tem sido alvo de grandes discussões que vão desde o entendimento de sua fisiopatologia até a investigação de novas modalidades terapêuticas. Reconhece-se que a necrose pancreática e a falência orgânica múltipla - mormente associadas à infecção - representam os principais fatores determinantes da evolução para o óbito, mas, apesar dos grandes avanços em seu estudo, a doença permanece como um desafio para o clínico e o cirurgião. Deste modo, um melhor conhecimento dos mecanismos envolvidos em sua fisiopatologia pode ser a chave para um tratamento mais eficaz, principalmente em relação às formas graves, cuja letalidade ainda encontra-se substancialmente elevada. Baseado nestas considerações, o presente trabalho tem por objetivo a revisão bibliográfica da fisiopatologia, dos fatores patogênicos envolvidos na história natural da pancreatite aguda grave e dos eventos associados à síndrome da resposta inflamatória sistêmica e à sepse, esboçando-se assim o mosaico patogênico desta importante condição.Acute pancreatitis has been the objective of discussion, principally regarding its physiopathology and treatment. It is recognized that pancreatic necrosis, infections and multiple organ dysfunction are associated with high mortality. This disease remains a challenge for physicians and surgeons. However, a better understanding of evolved mechanisms may be the key for an appropriated treatment, principally for severe forms of disease in which mortality remains elevated. This study reviews the physiopathology and natural history of severe acute pancreatitis, and its association to SIRS and sepsis.

    Full Text Available BackgroundHyperthyroidism relapse in Graves disease after antithyroid drug (ATD withdrawal is common; however, measuring the thyrotropin receptor antibody (TRAb at ATD withdrawal in order to predict outcomes is controversial. This study compared measurement of thyroid stimulatory antibody (TSAb and thyrotropin-binding inhibitory immunoglobulin (TBII at ATD withdrawal to predict relapse.MethodsThis retrospective study enrolled patients with Graves disease who were treated with ATDs and whose serum thyroid-stimulating hormone levels were normal after receiving low-dose ATDs. ATD therapy was stopped irrespective of TRAb positivity after an additional 6 months of receiving the minimum dose of ATD therapy. Patients were followed using thyroid function tests and TSAb (TSAb group; n=35 or TBII (TBII group; n=39 every 3 to 6 months for 2 years after ATD withdrawal.ResultsTwenty-eight patients (38% relapsed for a median follow-up of 21 months, and there were no differences in baseline clinical characteristics between groups. In the TSAb group, relapse was more common in patients with positive TSAb at ATD withdrawal (67% than patients with negative TSAb (17%; P=0.007. Relapse-free survival was shorter in TSAb-positive patients. In the TBII group, there were no differences in the relapse rate and relapse-free survivals according to TBII positivity. For predicting Graves disease relapse, the sensitivity and specificity of TSAb were 63% and 83%, respectively, whereas those of TBII were 28% and 65%.ConclusionTSAb at ATD withdrawal can predict the relapse of Graves hyperthyroidism, but TBII cannot. Measuring TSAb at ATD withdrawal can assist with clinical decisions making for patients with Graves disease.

    According to many guidelines, scintigraphy remains the first suggested diagnostic procedure in hyperthyroid patients in spite of the widespread availability of ultrasounds. The aim of this study was to evaluate the cost-effectiveness of sonography versus scintigraphy in the management of Graves's disease, and to assess ultrasound features suggesting cancer in detecting thyroid nodules. Among 1470 hyperthyroid patients evaluated in our department from 2002 to 2005, 426 (29%) had Graves' disease: echographic and scintigraphic features were not suggestive of GD in 20/426 (4.8%) and 11/426 (2.6%) patients, respectively (p = 0.763), even if one of the two procedures was almost always diagnostic. Ultrasound identified 68/426 (16%) patients with a concomitant solid lesion, while scintigraphy detected only 9/426 (2.1%) 'cold' nodules (p < 0.001). Thyroid cancer was diagnosed in 30/68 (47.7%) patients. Malignancy presented at ultrasound investigation blurred margins (26.7% versus 15.8%), microcalcifications (33.3% versus 28.9%) and an anteroposterior and transverse diameter ratio {>=}1 (73.3% versus 71.1%); more frequently than benign nodules, but this was not statistically significant. The total cost to obtain a diagnosis by ultrasound was Euro 14645.34 ( Euro 13312.5 for echography + Euro 1332.84 for scintigraphy in the 29 patients 'negative' at echographic evaluation for GD) versus Euro 19922.71 by scintigraphy ( Euro 19578.96 for scan + Euro 343.75 for ultrasounds in the 11 patients 'negative' at scintigraphy). Our data show no difference in terms of diagnosis between sonography and scintigraphy. Indeed, scintigraphy was less sensitive in detecting nodules (often of malignant nature) than ultrasound, and, moreover, with a consequent increase of the direct cost of nodule management when scintigraphy is the first line procedure. In conclusion, according to our results, we suggest that ultrasounds with color-Doppler evaluation should

Materials and methods: Dossiers of 226 patients submitted to radioiodine therapy for Graves' disease in the period between January 1990 and December 2001 were retrospectively evaluated. For the purposes of statistical analysis, the 12-year period was subdivided into three periods of 4 years, with a comparison of clinical and laboratory variables in these periods. Results: The authors have observed that the total number of patients referred for radioiodine therapy as well as the percentage of female patients presented a significant increase (from 62% to 86%; p = 0.005). The percentage of patients pretreated with methimazole before radioiodine therapy increased significantly (from 9.1% to 35.6%; p = 0.03). The mean radioiodine dose delivered has also presented a significant increase (from 7.6 mCi to 12.7 mCi; p = 0.000003) with a direct reflection on a higher percentage of patients cured one year after the radioiodine therapy (from 55.6% to 83.7%; p = 0.004). Conclusion: Radioiodine therapy has increasingly been accepted for treatment of patients with Graves' disease and the doses delivered have increased to achieve a permanent cure as well as a reduction of the chances of recurrence.

    Glomerular filtration rate (eGFR) by serum creatinine (eGFRCr) or standardized cystatin C (eGFRCysC) were estimated in Japanese patients with Graves׳ disease (GD) of different sex. Clinical samples were collected from patients with GD with normal renal function to accurately validate eGFRCr and eGFRCysC levels and evaluate how hyperthyroidism affects renal function. Levels of eGFRCr and eGFRCysC showed clinical usefulness in successfully treated euthyroid patients with GD regardless of sex. The article includes detailed experimental methods and data used in our analysis. The data relates to the "Paradoxical effect of thyroid function on the estimated glomerular filtration rate by serum creatinine or standardized cystatin C in Japanese Graves' disease patients" (Suzuki et al., 2015) [1].

    Ubiquitous media is not just a matter of (digital) media being everywhere and embedded in various objects (clothing, household hardware, buildings…). Using the practices of bereavement and commemoration as displayed by parents on children’s graves and online memorial sites as a case, this paper...... claims that ubiquitous media as a concept also relates to processes of mediatization (Cf. Hjarvard 2008, Lundbye 2009, Hepp 2013); to the ‘thingification of media’ (Lash & Lury 2007) and to everyday practices through which we (re)appropriate and change existing media ‘to suit our needs’ (Cf.

    Graves` disease presents itself clinically mainly as hyperthyroidism and infiltrative ophthalmopathy and to a minimal extent also as dermopathy and acropachy. Autoimmune processes are the basic pathogenesis. Stimulating antibodies against the TSH receptor cause hyperthyroidism. Autoantibodies and autoreactive T lymphocytes against primarily thyroidal antigens cross-react with similar antigens of the eye muscles and orbital connective tissue, thus spreading the disease from the thyroid to the eyes. The therapeutic goal comprises not only the treatment of hyperthyroidism, but also the induction of a steady immuntolerance in order to minimize the irreversible damage to the eye. The therapeutic armamentarium is formed by antithyroid drugs, glucocorticoids, retrobulbar radition and thyroid ablation, either by nearly total thyroidectomy or by radioiodine. The different indications for both ablative procedures are discussed. (orig.) [Deutsch] Der Morbus Basedow manifestiert sich klinisch hauptsaechlich als Hyperthyreose und infiltrative Orbitopathie, waehrend Demopathie und Akropathie selten sind. Der Krankheit liegt ein Autoimmunprozess zugrunde, wobei stimuliernde Autoantikoerper gegen den TSH-Rezeptor die Hyperthyreose hervorrufen. Autoantikoerper und T-Lymphozyten gegen primaer thyreoidale Antigene verursachen durch Kreuzreaktion mit aehnlichen Antigenen an den Augenmuskeln und orbitalem Bindegewebe die Orbitopathie. Das therapeutsiche Ziel besteht nicht nur in der Behandlung der Hyperthyreose, sondern vor allem in der Induktion einer immuntoleranten Remission, um die irreversiblen Schaeden am Auge zu minimieren. Die Therapie umfasst Thyreostatika, Glukokortikoide und Orbitaspitzenbestrahlung sowie eine Schilddruesenablation entweder durch fast totale Schilddruesenresektion oder durch Radiojodtherapie. Die Differentialindikationen fuer die beiden ablativen Massnahmen werden eroertert. (orig.)

    Full Text Available BackgroundThyrotoxic periodic paralysis (TPP is a rare complication of thyrotoxicosis characterized by acute attacks of muscle weakness and hypokalemia. Recently, variation in several genes was suggested to be associated with TPP. This study evaluated the genetic predisposition to TPP in terms of the β2-adrenergic receptor (ADRB2, androgen receptor (AR, and γ-aminobutyric acid receptor α3 subunit (GABRA3 genes.MethodsThis study enrolled 48 men with Graves disease (GD and TPP, and 48 GD patients without TPP. We compared the frequencies of candidate polymorphisms between the two groups.ResultsThe frequency of the Gly16/Gly16 genotype in ADRB2 was not significantly associated with TPP (P=0.32. More CAG repeats (≥26 in the AR gene were not correlated with TPP (odds ratio [OR], 2.46; 95% confidence interval [CI], 0.81 to 8.09; P=0.08. The allele frequency of the TT genotype in the GABRA3 gene was not associated with TPP (OR, 1.83; 95% CI, 0.54 to 6.74; P=0.41.ConclusionThe polymorphisms in the ADRB2, AR, and GABRA3 genes could not explain the genetic susceptibility to TPP in Korean men with GD.

    The aim of this article is to outline and assess an educational intervention programme targeted at improving the skills of families and the personal and social development of children living in situations of grave social vulnerability. The sample comprised 10 families during the first phase of the intervention and six during the second. The design, intervention and assessment process of this study was carried out in two phases over a period of a year and a half. For both phases, three different groups—of men/fathers, women/mothers and children—were established. Study variables (parenting skills and children's personal and social development) were evaluated before and after the intervention in every group, as well as during the entire process. The results, taking into account the improvements reported by all the participants (social workers, group monitors, fathers, mothers, children) show that inter-professional involvement and coordination at all phases of the intervention is vital in order to achieve small but significant improvements.

    Full Text Available Objective: The primary goal of this study is to evaluate predictors of nodular goiter in Graves Disease (GD.Materials and Methods: A total of 202 consecutive patients (mean age: 45; 145 female, 57 male were enrolled. All patients were treated with antithyroid drugs as initial therapy. TSH, FT3, FT4, TRAb, ATPO, and ATG were measured. Radioactive iodine uptake and thyroid ultrasonography were performed, and thyroid volume and nodule diameter were assessed. Ultrasound-guided fine needle aspiration was performed on thyroid nodules ≥8mm. Results: Diffuse goiter was detected in 51% of patients. Solitary nodules were detected in 16%, and multi-nodular disease in 33%. Mean nodule diameter was 8.82 mm. Nodular disease was slightly more common in women (p=0.063. Patients with nodular GD were older (p=0.004, had lower levels of FT3 (p=0.016 and TRAB (p=0.002 when compared with subjects with diffuse GD. Age (OR:6.867 was the independent variable predicting nodular GD. Conclusion: Increased prevalence of nodules was associated with advanced age and milder thyrotoxicosis. Apoptosis of thyroid follicular cells due to excess iodine might interfere with nodule formation, and lead to diffuse goiter in severe thyrotoxicosis. Because of increased rate if malignancy in GD, comprehensive evaluation of thyroid nodules of any size is mandatory. Turk Jem 2009; 13: 1-4

    Full Text Available To determine whether genetic heterogeneity exists in patients with Graves' disease (GD, the cytotoxic T-lymphocyte associated 4 (CTLA-4 gene, which is implicated a susceptibility gene for GD by considerable genetic and immunological evidence, was used for association analysis in a Chinese Han cohort recruited from various geographic regions. Our association study for the SNPs in the CTLA4 gene in 2640 GD patients and 2204 control subjects confirmed that CTLA4 is the susceptibility gene for GD in the Chinese Han population. Moreover, the logistic regression analysis in the combined Chinese Han cohort revealed that SNP rs231779 (allele frequencies p = 2.81x10(-9, OR = 1.35, and genotype distributions p = 2.75x10(-9, OR = 1.42 is likely the susceptibility variant for GD. Interestingly, the logistic regression analysis revealed that SNP rs35219727 may be the susceptibility variant to GD in the Shandong population; however, SNP, rs231779 in the CTLA4 gene probably independently confers GD susceptibility in the Xuzhou and southern China populations. These data suggest that the susceptibility variants of the CTLA4 gene varied between the different geographic populations with GD.

    Graves' disease is an autoimmune disorder that causes hyperthyroidism because of autoantibodies that bind to the thyroid-stimulating hormone receptor (TSHR) on the thyroid gland, triggering thyroid hormone release. The physiological control of thyroid hormone homeostasis by the feedback loops involving the hypothalamus-pituitary-thyroid axis is disrupted by these stimulating autoantibodies. To reset the endogenous thyrotrophic feedback control, we designed a synthetic mammalian gene circuit that maintains thyroid hormone homeostasis by monitoring thyroid hormone levels and coordinating the expression of a thyroid-stimulating hormone receptor antagonist (TSHAntag), which competitively inhibits the binding of thyroid-stimulating hormone or the human autoantibody to TSHR. This synthetic control device consists of a synthetic thyroid-sensing receptor (TSR), a yeast Gal4 protein/human thyroid receptor-α fusion, which reversibly triggers expression of the TSHAntag gene from TSR-dependent promoters. In hyperthyroid mice, this synthetic circuit sensed pathological thyroid hormone levels and restored the thyrotrophic feedback control of the hypothalamus-pituitary-thyroid axis to euthyroid hormone levels. Therapeutic plug and play gene circuits that restore physiological feedback control in metabolic disorders foster advanced gene- and cell-based therapies.

    Full Text Available Após traumatismos crânio-encefálicos graves ocorre hipoxia cerebral, não apenas nas primeiras horas mas também durante vários dias da fase aguda. A saturação arterial de O2 é muitas vêzes normal, mas, com mais freqüência do que se supõe, existe anemia; como conseqüência do aumento da pressão intracraniana, da hipotensão arterial ou da alcalose respiratória, diminui o afluxo sangüíneo ao encéfalo, baixando a tensão do O2 celular, o que é demonstrado pela diminuição da tensão de O2 no sangue venoso provindo do encéfalo. Por isso, no tratamento da fase aguda pós-traumática deve-se, ao lado da normalização da pressão intracraniana, manter a pressão arterial, evitar a hiperventilação pulmonar mediante a administração de neuroplégicos e impedir a anemia mediante transfusões de sangue.

    In Graves' ophthalmopathy (GO) it is important to distinguish acute inflammation at an early stage, responsive to immunosuppressive treatment, from inactive fibrotic end stage disease, unresponsive to the same treatment. The purpose of this study was to identify the most relevant signal intensities on orbital MR imaging with contrast administration both to classify patients according to their clinical activity score (defined by a cut-off value of 3) and to make a prediction of patient's CAS. Such threshold was considered as widely used in literature. Sixteen consecutive patients with a diagnosis of GO in different phases of thyroid disease based on clinical and orbital MR imaging signs, and six normal volunteers were examined. Orbital MR imaging was performed on a 1.5 Tesla MR Unit. MR scans were assessed by an experienced neuroradiologist, blinded to the clinical examinations. We found a statistical correlation between CAS and both STIR and contrast enhanced T1-weighted sequences. There was also a statistically significant correlation between STIR and contrast-enhanced T1 images disclosing the possibility of avoiding the injection of contrast medium. Our study proved that signal intensity values on STIR sequence increase in the inflammatory oedematous phase of disease. We confirmed the correlation between signal intensities on this sequence and CAS, showing an increase in signal intensity proportional to the CAS value. So we validated MRI use to establish the activity phase of disease more sensitively than CAS alone.

Pre-existing pattern of development of autoimmune thyroiditis (Hashimoto's thyroiditis and Graves' disease (GD as a state with two opposite positions of the predominant profile of Th1/Th2-lymphocyte activation. The study evaluated the cytokine production by Th1- and Th2-lymphocytes in patients with GD, assessment of lymphocyte receptor system and identified lymphocytes subpopulation in patients with BG, and the impact on the functional state of thyroid gland. It was shown that the immunoregulatory cytokines as Th1(IL2- and Th2(IL-4-helper lymphocytes are involved in the immune mechanism of BG. The level of IL-2, IL4, and TNF-α, and the number complementary lymphocyte receptors were not significantly changed in euthyroid or hyperthyroid GD patient. Nevertheless, there are strong correla! tions between production of immunoregulatory cytokines (IL-2, IL-4 with the functional state of the thyroid gland and increase of its volume in GD patient, what confirms the “functional synergies” of these cytokines in autoimmune inflammation in the GD.

    Objective: to compare ultrasonography (US) to magnetic resonance imaging (MRI) and the clinical activity score (CAS) in Graves' ophthalmopathy. Subjects and methods: Nineteen patients underwent extraocular muscle thickness measurements by US and MRI, reflectivity by US and signal-intensity ratio by MRI. There were also twelve US control subjects. Results: US median thicknesses were greater than in controls. Correlation was found between US and MRI in the median thickness of the left eye rectus medial muscle as well as between signal-intensity ratio (SIR) and thickness by US. An inverse correlation was found between reflectivity and SIR in the inferior and lateral rectus. On associating the tests for detecting activity the best results were obtained with CAS plus MRI (sensitivity 75%), and US and MRI (positive predictive value 77% and specificity 80%). Conclusion: CAS and US results showed poor correlation with MRI results suggesting that they cannot replace each other but when combined these methods can improve the evaluation of thyroid-associated ophthalmopathy.

    Graves' disease (GD) may display uncommon manifestations. We report a patient with rare complications of GD and present a comprehensive literature review. A 35-year-old woman presented with a two-week history of dyspnea, palpitations, and edema. She had a raised jugular venous pressure, goiter, and exophthalmos. Laboratory tests showed pancytopenia, a raised alkaline phosphatase level, hyperbilirubinemia (mainly direct bilirubin), and hyperthyroidism [TSH: 46.08 pmol/L (reference values: 2.6–5.7)]. Her thyroid uptake scan indicated GD. Echocardiography showed a high right ventricular systolic pressure: 60.16 mmHg. Lugol's iodine, propranolol, cholestyramine, and dexamethasone were initiated. Hematologic investigations uncovered no reason for the pancytopenia; therefore, carbimazole was started. Workup for hepatic impairment and pulmonary hypertension (PH) was negative. The patient became euthyroid after 3 months. Leukocyte and platelet counts and bilirubin levels normalized, and her hemoglobin and alkaline phosphatase levels and right ventricular systolic pressure (52.64 mmHg) improved. This is the first reported single case of GD with the following three rare manifestations: pancytopenia, cholestatic liver injury, and PH with right-sided heart failure. With antithyroid drugs treatment, pancytopenia should resolve with euthyroidism, but PH and liver injury may take several months to resolve. PMID:28348902

    Paroxysmal non-kinesigenic dyskinesia (PNKD) is a rare hyperkinetic movement disorder and falls under the category of paroxysmal movement disorders. In this condition, episodes are spontaneous, involuntary, and involve dystonic posturing with choreic and ballistic movements. Attacks last for minutes to hours and rarely occur more than once per day. Attacks are not typically triggered by sudden movement, but may be brought on by alcohol, caffeine, stress, fatigue, or chocolate. We report a patient with multiple atypical features of PNKD. She had a 7-year history of this condition with onset at the age of 59, and a remote history of Graves' disease requiring total thyroidectomy. The frequency of attacks in our case ranged from five to six times a day to a minimum of twice per week, and the duration of episode was short, lasting not more than 2 min. Typically, PNKDs occur at a much younger age and have longer attack durations with low frequency. Administering clonazepam worked to reduce her symptoms, although majority of previous research suggests that pharmacological interventions have poor outcomes.

Sixteen consecutive patients with a diagnosis of GO in different phases of thyroid disease based on clinical and orbital MR imaging signs, and six normal volunteers were examined. Orbital MR imaging was performed on a 1.5 Tesla MR Unit. MR scans were assessed by an experienced neuroradiologist, blinded to the clinical examinations. We found a statistical correlation between CAS and both STIR and contrast enhanced T1-weighted sequences. There was also a statistically significant correlation between STIR and contrast-enhanced T1 images disclosing the possibility of avoiding the injection of contrast medium. Our study proved that signal intensity values on STIR sequence increase in the inflammatory oedematous phase of disease. We confirmed the correlation between signal intensities on this sequence and CAS, showing an increase in signal intensity proportional to the CAS value. So we validated MRI use to establish the activity phase of disease more sensitively than CAS alone. PMID:24199816

    Full Text Available El síndrome hemofagocítico constituye una entidad infrecuente, heterogénea, subdiagnosticada, y muchas veces fatal. En los casos secundarios, los desencadenantes pueden ser numerosos, tales como infecciones, fármacos, enfermedades autoinmunes y neoplasias. El mecanismo fisiopatogénico se explica por la presencia de una función disminuida o defectuosa de células NK y linfocitos T citotóxicos, que resulta en una activación inmune inefectiva y descontrolada, conduciendo al daño celular, falla multiorgánica y proliferación macrofágica con hemofagocitosis. Existen diferentes opciones terapéuticas, mayormente combinaciones de citostáticos y esteroides, cuyo objetivo es la supresión de la respuesta inmune descontrolada. Ocasionalmente, la condición clínica de algunos pacientes con síndrome hemofagocítico impide la utilización de esquemas terapéuticos intensivos. Comunicamos el caso de un paciente quemado grave, que reúne los criterios diagnósticos de síndrome hemofagocítico, quien presentó una evolución favorable con el tratamiento combinado de esteroides e inmunoglobulinas endovenosas.

    The rapid Arab-Islamic conquest during the early Middle Ages led to major political and cultural changes in the Mediterranean world. Although the early medieval Muslim presence in the Iberian Peninsula is now well documented, based in the evaluation of archeological and historical sources, the Muslim expansion in the area north of the Pyrenees has only been documented so far through textual sources or rare archaeological data. Our study provides the first archaeo-anthropological testimony of the Muslim establishment in South of France through the multidisciplinary analysis of three graves excavated at Nimes. First, we argue in favor of burials that followed Islamic rites and then note the presence of a community practicing Muslim traditions in Nimes. Second, the radiometric dates obtained from all three human skeletons (between the 7th and the 9th centuries AD) echo historical sources documenting an early Muslim presence in southern Gaul (i.e., the first half of 8th century AD). Finally, palaeogenomic analyses conducted on the human remains provide arguments in favor of a North African ancestry of the three individuals, at least considering the paternal lineages. Given all of these data, we propose that the skeletons from the Nimes burials belonged to Berbers integrated into the Umayyad army during the Arab expansion in North Africa. Our discovery not only discusses the first anthropological and genetic data concerning the Muslim occupation of the Visigothic territory of Septimania but also highlights the complexity of the relationship between the two communities during this period.

    In most Latin American countries there are significant numbers of missing people and forced disappearances, currently 80,000 only in Colombia. Successful detection of shallow buried human remains by forensic search teams is currently difficult in varying terrain and climates. Within this research we built four simulated clandestine burial styles in tropical rainforests, as this is a common scenario and depositional environment encountered in Latin America, to gain knowledge of optimum forensic geophysics detection techniques. The results of geophysically monitoring these burials using ground penetrating radar, magnetic susceptibility, bulk ground conductivity and electrical resistivity are presented from one to forty three weeks post-burial. Radar survey results with both the 250 MHz and 500 MHz frequency antennae showed good detection of modern simulated burials on 2D profiles and horizontal time slices but poor detection on the other simulated graves. Magnetic susceptibility, bulk ground conductivity and electrical resistivity results were generally poor at detecting the simulated targets. Observations of botanical variations on the test site show rapid regrowth of Malvaceae and Petiveria alliacea vegetation over all burials that are common in these forests, which can make detection more difficult.

    In most Latin American countries there are significant numbers of both missing people and forced disappearances, ∼71,000 Colombia alone. Successful detection of buried human remains by forensic search teams can be difficult in varying terrain and climates. Three clandestine burials were simulated at two different depths commonly encountered in Latin America. In order to gain critical knowledge of optimum geophysical detection techniques, burials were monitored using: ground penetrating radar, magnetic susceptibility, bulk ground conductivity and electrical resistivity up to twenty-two months post-burial. Radar survey results showed good detection of modern 1/2 clothed pig cadavers throughout the survey period on 2D profiles, with the 250MHz antennae judged optimal. Both skeletonised and decapitated and burnt human remains were poorly imaged on 2D profiles with loss in signal continuity observed throughout the survey period. Horizontal radar time slices showed good anomalies observed over targets, but these decreased in amplitude over the post-burial time. These were judged due to detecting disturbed grave soil rather than just the buried targets. Magnetic susceptibility and electrical resistivity were successful at target detection in contrast to bulk ground conductivity surveys which were unsuccessful. Deeper burials were all harder to image than shallower ones. Forensic geophysical surveys should be undertaken at suspected burial sites.

    A study was conducted to investigate the effect of Lugol's iodine on the superior thyroid artery (STA) blood flow with use of a Duplex ultrasound scanner for 12 patients with Graves' disease. All patients were treated with antithyroid drugs until they were euthyroid and then, with randomization, the patients received either Lugol's iodine, 0.3 ml thrice daily, or placebo for 9 days in a double-blind fashion. Antithyroid drugs were continued throughout the study. Reduction in the diameter, time-averaged velocity (TAV), and volume flow (VF) of the STAs was demonstrated in all patients in the treatment group, whereas there were no consistent trends in the placebo group. The changes in TAV and VF were significantly different between the placebo and treatment groups (p less than 0.01 for TAV and p less than 0.005 for VF). These changes were more marked in patients with high initial VF and minimal in patients with low initial VF. On the basis of these results, we recommend that patients with high thyroid blood flow before thyroidectomy should receive Lugol's iodine preoperatively.

    Objectives. To evaluate the prevalence of infertility in women with Graves' disease (GD) or Hashimoto's thyroiditis (HT) and associated factors. Material and Methods. This cross-sectional study was conducted at the Endocrinology Clinic for Thyroid Autoimmune Diseases, with 193 women aged 18-50 years with GD and 66 women aged 18-60 years with HT. The women were interviewed to obtain data on their gynecological and obstetric history and family history of autoimmune diseases. Their medical records were reviewed to determine the characteristics of the disease and to confirm association with other autoimmune diseases. Infertility was defined as 12 months of unprotected sexual intercourse without conception. Results. The prevalence of infertility was 52.3% in GD and 47.0% in HT. Mean age at diagnosis was 36.5 years and 39.2 years, in GD and HT, respectively. The mean number of pregnancies was lower in women who were 35 years old or younger at diagnosis and was always lower following diagnosis of the disease, irrespective of age. The only variable associated with infertility was a shorter time of the disease in HT. Conclusions. The prevalence of infertility was high in women with GD and HT and affected the number of pregnancies in young women.

    Summary Myxoedema madness was first described as a consequence of severe hypothyroidism in 1949. Most cases were secondary to long-standing untreated primary hypothyroidism. We present the first reported case of iatrogenic myxoedema madness following radioactive iodine ablation for Graves' disease, with a second concurrent diagnosis of primary hyperaldosteronism. A 29-year-old woman presented with severe hypothyroidism, a 1-week history of psychotic behaviour and paranoid delusions 3 months after treatment with radioactive iodine ablation for Graves' disease. Her psychiatric symptoms abated with levothyroxine replacement. She was concurrently found to be hypertensive and hypokalemic. Primary hyperaldosteronism from bilateral adrenal hyperplasia was diagnosed. This case report serves as a reminder that myxoedema madness can be a complication of acute hypothyroidism following radioactive iodine ablation of Graves' disease and that primary hyperaldosteronism may be associated with autoimmune hyperthyroidism. Learning points Psychosis (myxoedema madness) can present as a neuropsychiatric manifestation of acute hypothyroidism following radioactive iodine ablation of Graves' disease.Primary hyperaldosteronism may be caused by idiopathic bilateral adrenal hyperplasia even in the presence of an adrenal adenoma seen on imaging.Adrenal vein sampling is a useful tool for differentiating between a unilateral aldosterone-producing adenoma, which is managed surgically, and an idiopathic bilateral adrenal hyperplasia, which is managed medically.The management of autoimmune hyperthyroidism, iatrogenic hypothyroidism and primary hyperaldosteronism from bilateral idiopathic adrenal hyperplasia in patients planning pregnancy includes delaying pregnancy 6 months following radioactive iodine treatment and until patient is euthyroid for 3 months, using amiloride as opposed to spironolactone, controlling blood pressure with agents safe in pregnancy such as nifedipine and avoiding

    Objective: Several methods are utilized for determining the radioiodine activity in the treatment of Graves' disease (hyperthyroidism). Some of this methods do not take into consideration the thyroid absorbed dose or the necessary parameters for this estimation. The association between absorbed dose and administered activity depends on effective half-life, iodine uptake and thyroid mass of each patient. The present study was aimed at developing a methodology for individualized {sup 131}I therapy for Graves' disease in patients with hyperthyroidism of the Graves' disease. Materials and methods: A neck-thyroid phantom developed at Instituto de Radioprotecao e Dosimetria, containing a standard solution of {sup 131}I, was utilized for calibrating the scintillation gamma camera and uptake probe installed in the Department of Nuclear Medicine of the Hospital Universitario Clementino Fraga Filho da Universidade Federal do Rio de Janeiro. Results: The view angle of the collimator/detector assembly presented values compatible with the thyroid gland size for distances of 25 cm (uptake probe) and 45.8 cm (scintillation gamma camera). Calibration factors were 39.3 {+-} 0.78 and 4.3 {+-} 0.17 cpm/kBq, respectively. The 14-30-hour interval in the retention curve allows the estimation of activity between two points for determining the effective iodine half-life in the thyroid. Conclusion: The utilization of equipment usually available in nuclear medicine clinics is feasible, so this is a simple, effective and low cost methodology. (author)

    In most Latin American countries there are significant numbers of missing people and forced disappearances, 68,000 alone currently in Colombia. Successful detection of shallow buried human remains by forensic search teams is difficult in varying terrain and climates. This research has created three simulated clandestine burial styles at two different depths commonly encountered in Latin America to gain knowledge of optimum forensic geophysics detection techniques. Repeated monitoring of the graves post-burial was undertaken by ground penetrating radar. Radar survey 2D profile results show reasonable detection of ½ clothed pig cadavers up to 19 weeks of burial, with decreasing confidence after this time. Simulated burials using skeletonized human remains were not able to be imaged after 19 weeks of burial, with beheaded and burnt human remains not being able to be detected throughout the survey period. Horizontal radar time slices showed good early results up to 19 weeks of burial as more area was covered and bi-directional surveys were collected, but these decreased in amplitude over time. Deeper burials were all harder to image than shallower ones. Analysis of excavated soil found soil moisture content almost double compared to those reported from temperate climate studies. Vegetation variations over the simulated graves were also noted which would provide promising indicators for grave detection.

    Aim: Graves' hyperthyroidism and antithyroid drugs empty the intrathyroid stores of hormones and iodine. The consequence is rapid {sup 131}I turnover and impending failure of radioiodine therapy. Can administration of additional inactive iodide improve 131I kinetics? Patients, methods: Fifteen consecutive patients, in whom the 48 h post-therapeutically calculated thyroid dose was between 150 and 249 Gy due to an unexpectedly short half-life, received 3 x 200 {mu}g inactive potassium-iodide ({sup 127}I) daily for 3 days (Group A), while 17 consecutive patients with a thyroid dose of = 250 Gy (Group B) served as the non-iodide group. 48 hours after {sup 131}I administration (M1) and 4 or 5 days later (M2) the following parameters were compared: effective {sup 131}I half-life, thyroid dose, total T3, total T4, {sup 131}I-activity in the T3- and T4-RIAs. Results: In Group A, the effective {sup 131}I half-life M1 before iodine (3.81 {+-} 0.93 days) was significantly (p <0.01) shorter than the effective {sup 131}I half-life M2 (4.65 {+-} 0.79 days). Effective {sup 131}I half-life M1 correlated with the benefit from inactive {sup 127}I (r = -0.79): Administration of {sup 127}I was beneficial in patients with an effective {sup 131}I half-life M1 of <3 or 4 days. Patients from Group A with high initial specific {sup 131}I activity of T3 and T4 showed lower specific {sup 131}I activity after addition of inactive iodine compared with patients from the same group with a lower initial specific {sup 131}I activity of T3 and T4 and compared with the patient group B who was given no additional inactive iodide. This correlation was mathematically described and reflected in the flatter gradient in Group A (y = 0.5195x + 0.8727 for {sup 131}I T3 and y = 1.0827x - 0.4444 for {sup 131}I T4) and steeper gradient for Group B (y = 0.6998x + 0.5417 for {sup 131}I T3 and y = 1.3191x - 0.2901 for {sup 131}I T4). Radioiodine therapy was successful in all 15 patients from Group A

    Full Text Available On May 1st, 2014 members of the historical memory team from the Aranzadi Sciences Society arrived in Oropesa de Toledo. The objective: to locate two mass graves containing the remains of Republicans killed in the weeks after Franco’s troops entered the town in 1936. Despite evidence regarding the mass graves’ existence, they were never found. Drawing on empirical, ethnographic data collected in the town of Oropesa in the months following this “unsuccessful” exhumation, this paper narrates the curious story of two graves that have “gone missing.” It considers the intellectual labor exerted to produce historical knowledge in a context where municipal archives remain inaccessible and family histories are marked by silence and dis-information. The author suggests that the absence of information –the dearth of historical, narrative evidence– regarding the lives of the defeated makes the production of historical and forensic knowledge a complicated affair. It tracks how kin-based knowledge and scarce archival documents are gathered and animated in order to make exhumations possible. Considering the forms of knowledge that are needed in order to engage techno-scientific expertise in meaningful ways, the paper attends to the important role that kin-based knowledge and seemingly “unimportant” documents play in processes of historical enunciation.El 1 de mayo de 2014, los miembros del equipo forense de la Sociedad de Ciencias Aranzadi llegaron a Oropesa de Toledo.

    The human leukocyte antigen (HLA) genomic region spanning about 4 Mb is the most gene dense and the polymorphic stretches in the human genome. A total of the 269 loci were identified, including 145 protein coding genes mostly important for immunity and 50 noncoding RNAs (ncRNAs). Biological function of these ncRNAs remains unknown, becoming hot spot in the studies of HLA-associated diseases. The genomic diversity analysis in the HLA region facilitated by next-generation sequencing will pave the way to molecular understanding of linkage disequilibrium structure, population diversity, histocompatibility in transplantation, and associations with autoimmune diseases. The 4-digit DNA genotyping of HLA for six HLA loci, HLA-A through DP, in the patients with Graves' disease (GD) and Hashimoto thyroiditis (HT) identified six susceptible and three resistant HLA alleles. Their epistatic interactions in controlling the development of these diseases are shown. Four susceptible and one resistant HLA alleles are shared by GD and HT. Two HLA alleles associated with GD or HT control the titers of autoantibodies to thyroid antigens. All these observations led us to propose a new model for the development of GD and HT. Hematopoietic stem cell transplantation from unrelated donor (UR-HSCT) provides a natural experiment to elucidate the role of allogenic HLA molecules in immune response. Large cohort studies using HLA allele and clinical outcome data have elucidated that (1) HLA locus, allele, and haplotype mismatches between donor and patient, (2) specific amino acid substitution at specific positions of HLA molecules, and (3) ethnic background are all responsible for the immunological events related to UR-HSCT including acute graft-versus-host disease (GVHD), chronic GVHD, graft-versus-leukemia (GvL) effect, and graft failure.

    Graves' ophthalmopathy (GO) is a disfiguring and sometimes blinding disease, which is characterized by inflammation and swelling of orbital tissues, with fibrosis and adipogenesis being predominant features. The aim of this study is to investigate whether the expression levels of fibrosis-related genes, especially that of connective tissue growth factor (CTGF), are altered in orbital fibroblasts of patients with GO. The role of oxidative stress in the regulation of CTGF expression in GO orbital fibroblasts is also examined. By a SYBR Green-based real time quantitative PCR (RT-QPCR), we demonstrated that the mRNA expression levels of fibronectin, apolipoprotein J, and CTGF in cultured orbital fibroblasts from patients with GO were significantly higher than those of age-matched normal controls (p = 0.007, 0.037, and 0.002, respectively). In addition, the protein expression levels of fibronectin, apolipoprotein J, and CTGF analyzed by Western blot were also significantly higher in GO orbital fibroblasts (p = 0.046, 0.032, and 0.008, respectively) as compared with the control. Furthermore, after treatment of orbital fibroblasts with a sub-lethal dose of hydrogen peroxide (200 μM H2O2), we found that the H2O2-induced increase of CTGF expression was more pronounced in the GO orbital fibroblasts as compared with those in normal controls (20% vs. 7%, p = 0.007). Importantly, pre-incubation with antioxidants including N-acetylcysteine (NAC) and vitamin C, respectively, resulted in significant attenuation of the induction of CTGF in GO orbital fibroblasts in response to H2O2 (p = 0.004 and 0.015, respectively). Taken together, we suggest that oxidative stress plays a role in the alteration of the expression of CTGF in GO orbital fibroblasts that may contribute to the pathogenesis and progression of GO. Antioxidants may be used in combination with the therapeutic agents for effective treatment of GO.

    Full Text Available Objetivo: Analisar os desfechos aumento/diminuição da pressão intracraniana e/ou queda da pressão de perfusão cerebral, proporcionados pela fisioterapia respiratória em pacientes graves assistidos em unidade de terapia intensiva. Métodos: Por meio de uma revisão sistemática da literatura, foram selecionados ensaios clínicos publicados entre 2002 e 2012. A busca envolveu as bases de dados LILACS, SciELO, MedLine e PEDro, usando os descritores "physical therapy", "physiotherapy", "respiratory therapy" e "randomized controlled trials" em cruzamento com o descritor "intracranial pressure". Resultados: Foram incluídos 5 estudos, que somaram 164 pacientes, com média de idade entre 25 e 65 anos, e que indicaram que as manobras de fisioterapia respiratória aumentaram significativamente a pressão intracraniana, sem alterar a pressão de perfusão cerebral. Os artigos abordaram as técnicas de vibração, vibrocompressão, tapotagem, drenagem postural, além da manobra de aspiração intratraqueal. Todos os pacientes estavam sob ventilação mecânica invasiva. Conclusão: A fisioterapia respiratória promove aumento da pressão intracraniana. Os estudos sugerem que não há repercussões hemodinâmicas e respiratórias a curto prazo ou alteração da pressão de perfusão cerebral. Entretanto, não há estudos que avaliem desfechos clínicos e que assegurem a segurança das manobras.

    Graves' disease (GD) is an autoimmune oligogenic disorder with a strong hereditary component. Several GD susceptibility genes have been identified and confirmed during the last two decades. However, there are very few studies that evaluated susceptibility genes for GD in specific geographic subsets. Previously, we mapped a new locus on chromosome 3q that was unique to GD families of Italian origin. In the present study, we used association analysis of single-nucleotide polymorphism (SNPs) at the 3q locus in a cohort of GD patients of Italian origin in order to prioritize the best candidates among the known genes in this locus to choose the one(s) best supported by the association. DNA samples were genotyped using the Illumina GoldenGate genotyping assay analyzing 690 SNP in the linked 3q locus covering all 124 linkage disequilibrium blocks in this locus. Candidate non-HLA (human-leukocyte-antigen) genes previously reported to be associated with GD and/or other autoimmune disorders were analyzed separately. Three SNPs in the 3q locus showed a nominal association (p < 0.05): rs13097181, rs763313, and rs6792646. Albeit these could not be further validated by multiple comparison correction, we were prioritizing candidate genes at a locus already known to harbor a GD-related gene, not hypothesis testing. Moreover, we found significant associations with the thyroid-stimulating hormone receptor (TSHR) gene, the cytotoxic T-lymphocyte antigen-4 (CTLA-4) gene, and the thyroglobulin (TG) gene. In conclusion, we identified three SNPs on chromosome 3q that may map a new GD susceptibility gene in this region which is unique to the Italian population. Furthermore, we confirmed that the TSHR, the CTLA-4, and the TG genes are associated with GD in Italians. Our findings highlight the influence of ethnicity and geographic variations on the genetic susceptibility to GD.

    Full Text Available About 25-50% of Graves' disease (GD patients develop thyroid eye diseases, which is associated with inflammatory process and abnormalities in the levels of several cytokines in orbital tissues in GD.  The aim of this study was to determine the Th1 and Th2 serum cytokines in patients with GD with or without ophthalmopathy.Serum  levels of  cytokines  and  autoantibodies  including Interferon-gamma  (IFN-γ,Interleukin-2 (IL-2, Interleukin-4 (IL-4, Interleukin-10 (IL-10, TSH receptor autoantibody (TRAb, thyroid  peroxidase antibody (TPOAb  and  thyroglobulin antibody(TgAb were measured by enzyme linked immunosorbent assay(ELISA in 34 patients with GD and in 33 normal controls. Patients were also divided in two subgroups: 18 cases with ophthalmopathy and 16 cases without ophthalmopathy. Cytokine and antibody responses were analyzed in both groups.Compared with control subjects, patients with GD  showed elevated levels of IL-2 and IL-10. IFN-γ  levels were lower in patients in comparison to the controls. No significant differences were found  between patients and controls regarding the IL-4. There was no statistically significant  difference  in  cytokine  levels  between  those   with  or   without ophthalmopathy.Quantitative-cytokine  analysis  demonstrated  that  a  combination  of  Th1  and  Th2 cytokines may contribute to the pathogenesis of GD. These results also indicate that IL-10, but not IL-4, is related to the moderate and severe forms of thyroid associated ophthalmophathy.

    Full Text Available Abstract Background We previously reported that depressive personality (the scores of hypochondriasis, depression and psychasthenia determined by the Minnesota Multiphasic Personality Inventory (MMPI and daily hassles of Graves' disease (GD patients treated long trem with antithyroid drug (ATD were significantly higher in a relapsed group than in a remitted group, even in the euthyroid state. The present study aims to examine the relationship among depressive personality, emotional stresses, thyroid function and the prognosis of hyperthyroidism in newly diagnosed GD patients. Methods Sixty-four untreated GD patients responded to the MMPI for personality traits, the Natsume's Stress Inventory for major life events, and the Hayashi's Daily Life Stress Inventory for daily life stresses before and during ATD treatment. Results In the untreated thyrotoxic state, depressive personality (T-scores of hypochondriasis, depression or psychasthenia greater than 60 points in MMPI were found for 44 patients (69%. For 15 (23% of these patients, the scores decreased to the normal range after treatment. However, depressive personality persisted after treatment in the remaining 29 patients (46%. Normal scores before treatment were found for 20 patients (31%, and the scores were persistently normal for 15 patients (23%. The remaining 5 patients (8% had higher depressive personality after treatment. Such depressive personality was not associated with the severity of hyperthyroidism. Serum TSH receptor antibody activity at three years after treatment was significantly (p = 0.0351 greater in the depression group than in the non- depression group. The remission rate at four years after treatment was significantly (p = 0.0305 lower in the depression group than in the non- depression group (22% vs 52%. Conclusion The data indicate that in GD patients treated with ATD, depressive personality during treatment reflects the effect of emotional stress more than that of

    Early (20 min) thyroid radio-iodine uptake (ERU) and thyroid-stimulating antibodies (TSab) were determined in 27 untreated unselected patients with Graves' disease at the time of diagnosis. In 21 subjects the same tests were further performed in parallel during combined carbimazole-L-T3 therapy (mean duration of follow-up: 10.8 +/- 5.8 months; mean +/- SD). TSab was determined by a cAMP-human thyrocyte culture stimulation assay and expressed in microliter-equivalent of a TSab standard/ml (microliter-eq/ml). Before treatment, ERU, ranging from 15 to 54% of the injected dose (normal less than or equal to 8% dose) correlated with serum T3 (r: 0.54; P less than 0.01); TSab, ranging from 6 to 85 microliter-eq/ml was detected in 21/27 patients. There was a significant correlation between ERU and TSab (Spearman rank test: r: 0.57; P less than 0.01). During the first months of treatment, 5 of the 21 patients sequentially studied had undetectable TSab levels throughout the study and in these patients ERU decreased by 57% of its initial value; the remaining 16 subjects were divided into two groups according to ERU changes: in group A (9 patients), initial ERU decreased by 50% or more or the absolute value became less than 20% of the dose and TSab decreased from 10.9 +/- 4.8 microliter-eq/ml to 5.3 +/- 1.6 microliter-eq/ml (P less than 0.01); in group B (7 patients), the fall of ERU was less than 50% or the absolute value remained greater than 20% of the dose and TSab values remained unchanged.(ABSTRACT TRUNCATED AT 250 WORDS)

  20. Thyroid storm associated with Graves' disease covered by diabetic ketoacidosis: A case report

    Science.gov (United States)

    2011-01-01

    Background Thyroid storm is a condition in which multiple organ dysfunction results from failure of the compensatory mechanisms of the body owing to excessive thyroid hormone activity induced by some factors in patients with thyrotoxicosis. While diabetic ketoacidosis (DKA) is an important trigger for thyroid storm, simultaneous development of DKA and thyroid storm is rare. Case presentation A 59-year-old woman with no history of either diabetes mellitus or thyroid disease presented to our hospital because of developing nausea, vomiting and diarrhea for 2 days. Physical examination showed mild disturbance of consciousness, fever, and tachycardia. There were no other signs of thyrotoxicosis. Laboratory studies revealed elevation of random blood glucose and glycosylated hemoglobin, strongly positive of urine acetone, and metabolic acidosis. Since DKA was diagnosed, we initiated the patient on treatment with administration of insulin and adequate fluid replacement. Although the hyperglycemia and acidosis were immediately relieved, the disturbance of consciousness and tachycardia remained persistent. Levels of FT3 and FT4 were extremely high and TSH was below the detectable limit. TRAb was positive. The thyroid storm score of Burch & Wartofsky was 75/140, and the thyroid storm diagnostic criteria of the Japan Thyroid Association were satisfied. Oral administration of thiamazole, potassium iodide and propranolol resulted in immediate relief of the tachycardia. Discussion We encountered a case of thyroid storm associated with Graves' disease covered by DKA. Thyroid storm and DKA are both potentially fatal, and the prognosis varies depending on whether or not these conditions are detected and treated sufficiently early. The thyroid storm diagnostic criteria prepared in 2008 by the Japan Thyroid Association are very simple as compared to the Burch & Wartofsky scoring system for thyroid storm. The Japanese criteria may be useful in the diagnosis of this condition since they

    Full Text Available This paper presents the results of TL and OSL dating of soil and fragments of bricks from a grave, which was occupied by two mummified nuns, found at "Luz" Monastery, located in the state of São Paulo, Brazil. The TL and OSL ages were compared to C-14 dating ones obtained from bone collagens of the mummies. The majority of the ages is related to the eighteenth century. The gamma-ray spectroscopy was used to evaluate natural radioisotope concentrations in the samples, and by using these concentrations the annual dose rates, from 3.0 to 5.3 Gy/kyr, were obtained. Neutron activation analysis was performed and the radioisotope contents results are in agreement with those obtained by gamma-ray spectroscopy. The contents of U, Th and Ce elements were higher than those found in usual sediments.Este artigo apresenta os resultados de datação por TL e OSL de solos, e fragmentos de tijolos de um túmulo, que foi ocupado por duas freiras mumificadas encontradas no Mosteiro da "Luz", localizado no Estado de São Paulo, Brasil. As idades encontradas por TL e OSL foram comparadas às obtidas a partir de C-14 dos colágenos contidos em amostras de osso das múmias. A maioria das idades obtidas são do século XVIII. A espectroscopia de radiação-gama foi utilizada para avaliar concentrações de radioisótopos naturais nas amostras e para calcular as taxas de dose anual que resultaram em 3,0 a 5,3 Gy/kano. As concentrações radioativas são próximas daquelas obtidas através de Análise por Ativação de Nêutrons. Os conteúdos de elementos U, Th e Ce são superiores aos encontrados na maioria dos sedimentos.

  2. Differences in Gene-Gene Interactions in Graves' Disease Patients Stratified by Age of Onset.

    Beata Jurecka-Lubieniecka

    Full Text Available Graves' disease (GD is a complex disease in which genetic predisposition is modified by environmental factors. Each gene exerts limited effects on the development of autoimmune disease (OR = 1.2-1.5. An epidemiological study revealed that nearly 70% of the risk of developing inherited autoimmunological thyroid diseases (AITD is the result of gene interactions. In the present study, we analyzed the effects of the interactions of multiple loci on the genetic predisposition to GD. The aim of our analyses was to identify pairs of genes that exhibit a multiplicative interaction effect.A total of 709 patients with GD were included in the study. The patients were stratified into more homogeneous groups depending on the age at time of GD onset: younger patients less than 30 years of age and older patients greater than 30 years of age. Association analyses were performed for genes that influence the development of GD: HLADRB1, PTPN22, CTLA4 and TSHR. The interactions among polymorphisms were analyzed using the multiple logistic regression and multifactor dimensionality reduction (MDR methods.GD patients stratified by the age of onset differed in the allele frequencies of the HLADRB1*03 and 1858T polymorphisms of the PTPN22 gene (OR = 1.7, p = 0.003; OR = 1.49, p = 0.01, respectively. We evaluated the genetic interactions of four SNPs in a pairwise fashion with regard to disease risk. The coexistence of HLADRB1 with CTLA4 or HLADRB1 with PTPN22 exhibited interactions on more than additive levels (OR = 3.64, p = 0.002; OR = 4.20, p < 0.001, respectively. These results suggest that interactions between these pairs of genes contribute to the development of GD. MDR analysis confirmed these interactions.In contrast to a single gene effect, we observed that interactions between the HLADRB1/PTPN22 and HLADRB1/CTLA4 genes more closely predicted the risk of GD onset in young patients.

    Purpose: To review our institutional outcomes of patients treated with radiation therapy (RT) for Graves' orbitopathy (GO), assess the role of orbital reirradiation, and identify prognostic factors of complete response (CR). Methods and Materials: This is a retrospective review of 211 patients who presented with a diagnosis of GO and received RT between January 2000-2010. RT dose was 20 Gy in 10 fractions. Patient median age was 51 years (range, 15-84 years), median follow-up was 11 months (range, 1-88 months). Patient symptoms included any combination of proptosis (90.9%), extraocular muscle dysfunction (78.9%), soft tissue signs (68.4%), and diplopia (58.4%). Corticosteroids were used as first-line therapy in 20.6% of patients. Among those who achieved either CR or partial response (PR), prognostic factors were evaluated. Results: Stabilization of disease without recurrence was clinically achieved overall in 202 patients (96.7%). At the completion of RT, 176 patients (84.2%) reported a symptomatic improvement of pretreatment symptoms. CR of GO symptoms was achieved using multiple treatment modalities, including RT by 93 patients (44.5%), of which 32 patients received RT only. Corticosteroids were discontinued in 97.8% of patients who received them as initial therapy. Surgical intervention following radiotherapy was required for 144 (68.9%) of all patients. Fourteen patients received orbital reirradiation for persistent or recurrent symptoms. Five of these achieved a CR, and the other nine achieved disease stabilization but retained persistent ocular symptoms. Long-term side effects of RT included dry eyes (12%). Of the prognostic factors we investigated, only gender predicted CR, which was less common in men (33.9%) than in women (49.7%) p = 0.0471. Conclusions: Orbital radiation for GO is an established treatment modality for patients. Orbital reirradiation is beneficial for patients who do not respond to initial RT or experience symptom recurrence without

    Full Text Available BACKGROUND: Graves' disease (GD is the leading cause of hyperthyroidism and thyroid eye disease inherited as a complex trait. Although geoepidemiology studies showed relatively higher prevalence of GD in Asians than in Caucasians, previous genetic studies were contradictory concerning whether and/or which human leukocyte antigen (HLA alleles are associated with GD in Asians. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a case-control association study (499 unrelated GD cases and 504 controls and a replication in an independent family sample (419 GD individuals and their 282 relatives in 165 families. To minimize genetic and phenotypic heterogeneity, we included only ethnic Chinese Han population in Taiwan and excluded subjects with hypothyroidism. We performed direct and comprehensive genotyping of six classical HLA loci (HLA-A, -B, -C, -DPB1, -DQB1 and -DRB1 to 4-digit resolution. Combining the data of two sample populations, we found that B*46:01 (odds ratio under dominant model [OR]  = 1.33, Bonferroni corrected combined P [P(Bc]  = 1.17 x 10⁻², DPB1*05:01 (OR  = 2.34, P(Bc = 2.58 x 10⁻¹⁰, DQB1*03:02 (OR  = 0.62, P(Bc  = 1.97 x 10⁻², DRB1*15:01 (OR  = 1.68, P(Bc = 1.22 x 10⁻² and DRB1*16:02 (OR  = 2.63, P(Bc  = 1.46 x 10⁻⁵ were associated with GD. HLA-DPB1*05:01 is the major gene of GD in our population and singly accounts for 48.4% of population-attributable risk. CONCLUSIONS/SIGNIFICANCE: These GD-associated alleles we identified in ethnic Chinese Hans, and those identified in other Asian studies, are totally distinct from the known associated alleles in Caucasians. Identification of population-specific association alleles is the critical first step for individualized medicine. Furthermore, comparison between different susceptibility/protective alleles across populations could facilitate generation of novel hypothesis about GD pathophysiology and indicate a new direction for future

    Full Text Available Os estudos que relacionaram lesão renal aguda (LRA e trauma surgiram durante a Segunda Guerra Mundial e, desde então, tem havido progressiva evolução dos cuidados para a prevenção da LRA. Entretanto, a determinação dos fatores de risco para o desenvolvimento de LRA pós-trauma permanece crucial e pode ajudar a reduzir esta complicação. OBJETIVO: Este estudo tem como objetivo identificar os fatores de risco para o desenvolvimento de LRA em pacientes com trauma grave e sua influência na mortalidade. Trata-se de um estudo retrospectivo com 75 pacientes incluídos por apresentarem trauma grave; seis foram excluídos por terem chegado ao hospital sem condições de ressuscitação. MÉTODO: As variáveis estudadas foram: idade, sexo, gravidade do trauma de acordo com Injury Severity Score (ISS e Escala de Coma de Glasgow (ECG, mecanismo de trauma, pressão arterial média na admissão, reposição volêmica nas primeiras 24h, níveis séricos de creatinina, uso de antibióticos nefrotóxicos, tempo de internação, necessidade de internação em UTI e mortalidade. RESULTADOS: A prevalência de LRA em traumatizados graves foi de 17,3%, sendo que os fatores associados à IRA nessa amostra foram TCE, ECG < 10. A mortalidade, o tempo de internação e a necessidade de UTI foram significativamente maiores nos pacientes que desenvolveram LRA. CONCLUSÕES: A identificação desses fatores de risco é de suma importância para a formulação de estratégias de atendimento aos pacientes vítimas de trauma grave, visando à prevenção da lesão renal aguda e da elevada mortalidade.

    The radioiodine is used as complementary treatment of thyroid cancer and as first choice for the treatment of Graves' disease, being efficient, safe and easy administration, but without there is a protocol defined. This work was evaluated the thyroid absorbed dose from its mass and maximum uptake of I-131 obtained in the examination of diagnostic radiology of radiotherapeutic patients undergoing treatment of Graves' disease. Based on the results, it is observed that the thyroid absorbed dose, as much in terms of mass as the maximum uptake of I-131 for different values of administered activity, varies significantly. The analysis of these parameters is an excellent indicator for the pre-define quantity of radionuclide that is administered to the patient in terms of the radiation dose required to achieve an efficient therapeutic treatment. Moreover, it was observed that the thyroid absorbed dose depends on the degree of pathology of the disease, its mass and of the maximum uptake of I-131. (author)

    Full Text Available PURPOSE: To develop an experimental model of severe acute pancreatitis in rabbits through a pancreatic ductal injection of sodium taurocholate. METHODS: Twenty-four albino rabbits of the New Zealand lineage were distributed into four groups of six animals (A, B, C and S. The rabbits of three experimental groups (A, B and C were submitted to a laparatomy and received a pancreatic ductal injection of 1ml/kg sodium taurocholate 5%. Also, they were submitted to further laparatomies after 4h, 8h and 12h, respectively. The control group (S was subdivided into two groups of three animals: in subgroup S1 only the pancreatic duct catheterization was performed whereas in subgroup S2 the pancreatic duct catheterization as well as an injection of 1ml/kg physiologic solution 0.9% were carried out. After 12 hours, the rabbits were evaluated. In the re-intervention, blood was collected to determine the amylasemia and a pancreatectomy was carried out to investigate interstitial infiltration, steatonecrosis and necrosis of the organ, using an optical microscope. RESULTS: There was an elevation of amylase in all groups thus proving the existence of acute pancreatitis. The size of the interlobular septum increased progressively with a greater variation between group S1 (0.13 and group C (0. 53 (p=0.035. While all the animals in group A exhibited focal cellular necrosis, it was more intense in the rabbits of group B and culminated with a high proportion of severe pancreatic necrosis in group C animals. The difference in the intensity of cellular necrosis showed statistic significance (p=0.001. CONCLUSION: The proposed experimental model demonstrated its reproducibility and effectiveness in producing severe acute pancreatitis in rabbits.OBJETIVO: Desenvolver modelo experimental de pancreatite aguda grave em coelhos por meio da injeção de taurocolato de sódio no ducto pancreático.

    Full Text Available The Morgado Superior cave is a karst cave located in the municipality of Tomar (Santarém, Portugal. As other caves of the same area, it has provided stratigraphic data and votive deposits falling within the Holocene, more precisely in a diachronic time range that extends from the Neolithic to the early Bronze Age. In the Morgado Superior cave there are multiple burials with a few votive objects like jars, bone artefacts and lithic tools (blades, arrowheads etc., beads, pendants, and other decorative items in association with more than 8,000 human bones: the number of the grave goods elements is low if compared with the number of individuals buried in the cave. Concerning the use-wear study, we analyzed the grave goods in order to understand both their meaning in this funerary context and their function in the economy of this prehistoric society. We focused on the most representative elements of the grave goods: arrowheads and knapped lithic artefacts. This study led us to understand that the majority of the grave goods were everyday objects but with a strong symbolic value. Since in the Morgado Superior Cave there are a lot of grave goods showing prior breaks, their symbolic value does not seem to be lost even if the objects were broken. Thus, the use-wear analysis of the grave goods from the Morgado Superior Cave allowed us to identify the strong symbolic value of these elements for that human community, but at the same time to hypothesize a funerary practice that did not provide a special respect for the body and the grave goods of those dead previously buried in the cave. For these reasons we hypothesize a progressive spoliation (probably ritual of the previous grave goods. Through the use-wear study of the knapped lithic assemblage of the Morgado Superior Cave it was possible to reconstruct part of the ritual activities that were carried out in the site: the 90% of the lithic artefacts are used objects, all of the artefacts have been

    The oxygen present in a human organism comes from numerous sources, but the major factor that causes variation in the isotopic composition of this element in a tissue is available drinking water. The isotopic ratio of oxygen in an organism's tissue, including that found in bones and teeth, reflects the isotopic oxygen composition typical for the area where a given individual developed and lived. Of particular interest with regard to this issue were a series of skeletons from the multiple grave discovered at the Funnel Beaker-Baden settlement at Bronocice (southern Poland). The question therefore arose whether the specimens buried in this grave were part of the local community. The oxygen isotope level was established using apatite isolated from bones or teeth. A femur and root dentine samples taken from permanent teeth were subjected to oxygen isotope analysis. The oxygen isotope level of the site was established on the basis of local water precipitation and measurements taken from the oxygen isotope concentration in apatite samples isolated from the bones of animals co-occurring with the studied human group. It has been found that the oxygen isotope levels in the bones and dentine of almost all the analysed specimens from the excavated site at Bronocice were within the established range for the area's environment, providing evidence for their local origin. Thus, it can be assumed that the analysed group inhabiting the macrosettlement at Bronocice during the Funnel Beaker phase of the Baden culture was most probably of local origin.

    Graves' ophthalmopathy (GO) is a potentially sight threatening orbital disease that can have a large negative impact on the quality of life of the patient. Studies on long-term effects of GO on the quality of life are few. The aim of this study is to evaluate the health-related quality of life in patients with GO, before and after orbital decompression surgery. This is a prospective, longitudinal, interventional study in which patients who had orbital decompression were given the Graves´ ophthalmopathy quality of life questionnaire (GO-QOL) before and after surgery. The GO-QOL is a disease specific instrument to measure health-related quality of life. The answers are transformed into scores from 0-100 on 2 subscales. Higher score indicates better health. An additional patient satisfaction questionnaire was also given post-surgery. A significant, long-term, improvement in quality of life after orbital decompression was noted (p orbital decompression to a fellow patient. Persistent disturbing oscillopsia was seen in 2% and persistent disturbing infraorbital nerve hypoesthesia in 8% of the patients. Orbital decompression surgery has a positive effect on quality of life for patients with severe GO. The GO-QOL questionnaire showed significant improvement in QOL-scores even many years after surgery.

    Full Text Available Even though pre-historic burials have been the favourite topic of research of Estonian archaeologists at least for the past century, the focus has been on their appearance, chronology, ethnic context and objects discovered in them. Burial tradition, as it reflects in the archaeological remnants, has hardly been studied. Research in the field over the past few years, as well as osteological analysis of bone material, which was first carried out in the 1990s, has introduced new findings in the funeral customs of our ancestors. The article examines funeral customs on the island of Saaremaa, and the ideology behind it. The main focus is on the final centuries of the prehistoric period and the beginning of the Middle Ages – more specifically, on changes brought along by Christianity, although the study also provides an overview of earlier customs. A separate chapter discusses the partial distribution of bones and objects in graves, objects determining the boundaries of graves, and traces of funeral rituals. This evidently reflects a set of traditions, and thus also conceptions about the otherworld, composed of multiple layers and differing considerably from the modern funeral tradition. Christianisation of the population of Saaremaa in the 13th century changed these conceptions beyond recognition over a very short period of time.

    In Graves' Ophthalmopathy, it is important to distinguish active inflammatory phase, responsive to immunosuppressive treatment, from fibrotic unresponsive inactive one. The purpose of this study is, first, to identify the relevant orbital magnetic resonance imaging signal intensities before treatment, so to classify patients according to their clinical activity score (CAS), discriminating inactive (CAS < 3) from active Graves' Ophthalmopathy (GO) (CAS > 3) subjects and, second, to follow post-steroid treatment disease. An observational study was executed on 32 GO consecutive patients in different phases of disease, based on clinical and orbital Magnetic Resonance Imaging parameters, compared to 32 healthy volunteers. Orbital Magnetic Resonance Imaging was performed on a 1.5 tesla Magnetic Resonance Unit by an experienced neuroradiologist blinded to the clinical examinations. In pre-therapy patients, compared to controls, a medial rectus muscle statistically significant signal intensity ratio (SIR) in short-time inversion recovery (STIR) (long TR/TE) sequence was found, as well as when comparing patients before and after treatment, both medial and inferior rectus muscle SIR resulted significantly statistically different in STIR. These increased outcomes explain the inflammation oedematous phase of disease, moreover after steroid administration, compared to controls; patients presented lack of that statistically significant difference, thus suggesting treatment effectiveness. In our study, we proved STIR signal intensities increase in inflammation oedematous phase, confirming STIR sequence to define active phase of disease with more sensibility and reproducibility than CAS alone and to evaluate post-therapy involvement.

In a longitudinal study, we assessed the influence of sex, age, antithyroid drugs, target radiation dose, target mass, applied activity, delivered dose, interval between last meal and application, and TSH, FT{sub 3} and FT{sub 4} levels on the outcome of radioiodine therapy. One hundred and forty-four patients (111 female, 33 male) suffering from Graves' disease (GD) and 563 patients (434 female, 129 male) with toxic nodular goitre (TNG) were entered in the study and followed up until 8 months after therapy. Treatment was defined as successful when the TSH level was found to be normal or elevated. Ninety-eight GD patients and 418 TNG patients were successfully treated. Forward stepwise multiple regression analysis models retained only the target mass in GD and the applied activity in TNG as significantly associated with the outcome of therapy. The predictive value of all variables involved was extremely low in both disease groups. Whereas concomitant antithyroid medication had no influence in GD, it adversely influenced radioiodine therapy of TNG. This effect may be attributed to a radioiodine ''steal phenomenon'' induced by TSH-stimulated normal thyroid tissue, which causes overestimation of the uptake in toxic nodules. (orig.)

  13. Remission of anorexia nervosa after thyroidectomy: A report of two cases with Graves' disease and anorexia nervosa

    Full Text Available Abstract We report two patients with anorexia nervosa and Graves' disease who received subtotal thyroidectomy for Graves' disease and concomitantly experienced remission from anorexia nervosa. Both were young women (aged 20 and 26 at the time of surgery. Both had well controlled thyroid function and eating behavior at the time of surgery. Both were followed for over five years without relapse of anorexia nervosa or hyperthyroidism. These cases suggest the existence of an endocrine factor originating from the thyroid gland that is involved in the pathogenesis of anorexia nervosa. Since patients of thyroidectomy can remain in good health with supplement of thyroxine alone, it can be hypothesized that this anorexigenic endocrine factor is an evolutionary relic not necessary for the normal function of humans and does not have physiological effects unless secreted beyond normal levels. Given that, it implies the existence of a creature in the animal kingdom for which such an anorexigenic hormone is essential for survival. Migrating birds eat beyond their caloric expenditure before migration and become anorexic for the duration of their flight. It is also known that their thyroid function is elevated during migration. The normal physiology of migration is a complex mechanism involving the hypothalamic, pituitary, thyroid, adrenal and reproductive hormones. The mechanism of disease, however, can be simpler. A review of the literature is presented that suggest a heretofore unreported thyroid hormone, which is involved in the regulation of migration behavior, may be the responsible factor behind anorexia nervosa.

    Aim: this study was performed to analyse the impact of the choice of antithyroid drugs (ATD) on the outcome of ablative radioiodine therapy (RIT) in patients with Graves' disease. Patients, material, methods: a total of 571 consecutive patients were observed for 12 months after RIT between July 2001 and June 2004. Inclusion criteria were the confirmed diagnosis of Graves' disease, compensation of hyperthyroidism and withdrawal of ATD two days before preliminary radioiodine-testing and RIT. The intended dose of 250 Gy was calculated from the results of the radioiodine test and the therapeutically achieved dose was measured by serial uptake measurements. The end-point measure was thyroid function 12 months offer RIT; success was defined as elimination of hyperthyroidism. The pretreatment ATD was retrospectively correlated with the results achieved. Results: relief from hyperthyroidism was achieved in 96% of patients. 472 patients were treated with carbimazole or methimazole (CMI) and 61 with propylthiouracil (PTU). 38 patients had no thyrostatic drugs (ND) prior to RIT. The success rate was equal in all groups (CMI 451/472; PTU 61/61; ND 37/38; p = 0.22). Conclusion: thyrostatic treatment with PTU achieves excellent results in ablative RIT, using an accurate dosimetric approach with an achieved post-therapeutic dose of more than 200 Gy. (orig.)

    Objectives To investigate the clinical characteristics of childhood Graves' disease, the efficacy of methima-zole (MMT) and the impact of thyrotropin receptor antibody (TRAb) level on MMT therapy. Methods Clinical data from 36 children diagnosed with Graves' disease and treated with MMT over 2 years were retrospectively analyzed. Results The main clinical manifestations of children with Graves' disease were increase in appetite (61.1%) accompanied by no weight gain (63.8%), palpitations (44.4%) and sweating (36.1%). A decline in academic performance (27.7%) and inattention (19.4%) were specific to childhood, and goiter (100%), tachycardia (44.4%) and proptosis (44.4%) were common. Among 36 cases, 6 cases were cured (2 cases relapsed), 4 cases achieved relief and symptoms of 26 cases were improved. The recovery rate and remission rate of children with 3 to 4 years MMT treatment course were higher than those of with under 3 years MMT treatment course (P<0.017), but no statistically significant difference was observed compared with children treated over 4 years (P=0.037). The TRAb levels at onset and at the end of 2 years treatment in the group of successfully tapered MMT treatment were different statistically comparing to the group of tapered MMT dosage with difficulty (P<0.001). Conclusions Graves' disease in children is often misdiagnosed or missed to be diagnosed due to its wide spectrum of clinical manifestations with subtle early signs. The children with sustained high level of TRAb are difficult to be relieved by MMT treatment. Appropriately extended antithyroid drug therapy and detection of TRAb level on a regular basis will contribute to the higher remission rate and the prognosis assessment.%目的 探讨儿童Graves 病临床特征、他巴唑(MMT)治疗疗效以及促甲状腺激素受体抗体(TRAb)水平对疗效的影响.方法 回顾性分析36 例确诊为Graves 病且正规使用MMT 治疗,总疗程达2 年以上患儿的临床资料.结果 儿童Graves

    Objective. Patients with Graves' disease (GD) have marked lymphocytic infiltration in their thyroid glands. We examined the gene for the variable regions of the α-chain of the Chinese T-cell receptor( Vα gene) in intrathyroidal Tcells to determine the role of T cells in the pathogenesis of GD and offer potential for the development of immunothera-peutic remedies for GD. Methods. We used the reverse transcription and polymerase chain reaction(RT-PCR) to amplify complementary DNA(cDNA) for the 18 known families of the Vα gene in intrathyroidal T cells from 5 patients with Graves' disease.The findings were compared with the results of peripheral blood T cells in the same patients as well as those in normalsubjects. Results. We found that marked restriction in the expression of T cell receptor Vα genes by T cells from the thyroidtissue of Chinese patients with GD(P < 0.001). An average of only 4.6 ± 1.52 of the 18 Vα genes were expressed insuch samples, as compared with 10.4 ± 2.30Vα genes expressed in peripheral blood T cells from the same patients.The pattem of expressed Vα genes differed from patient to patient with no clear predominance. Condusions. Expression of intrathyroidal T cell receptor Vα genes in GD is highly restricted suggesting the prima-cy of T cells in causing the disorders.

A presença de edema e alterações inespecíficas nas concentrações plasmáticas de proteínas; variáveis antropométricas alteradas, refletindo muito mais o rearranjo da água corporal total do que modificações do estado nutricional; estudos pouco conclusivos com a bioimpedância elétrica; ausência de dados relativos à aplicação da avaliação subjetiva global; indicadores bioquímicos alterados como conseqüência das mudanças metabólicas, entre outros, indicam as várias limitações dos métodos a esses pacientes. Na ausência de estudos que os validem, existem recomendações baseadas em evidências clínicas, observação e fundamentação nas alterações fisiopatológicas. Independentemente dos métodos, a observação clínica pela equipe de saúde é imprescindível em todas as etapas.

    Full Text Available Context: Most of the information on remission related factors in Grave's disease are derived from Western literature. It is likely that there may be additional prognostic factors and differences in the postdrug treatment course of Grave's disease in India. Aim: To study factors which predict remission/relapse in Grave's disease patients from South India. Also to establish if technetium (Tc uptake has a role in predicting remission. Subjects and Methods: Records of 174 patients with clinical, biochemical, and scintigraphic criteria consistent with Grave's disease, seen in our Institution between January 2006 and 2014 were analyzed. Patient factors, drug-related factors, Tc-99m uptake and other clinical factors were compared between the remission and nonremission groups. Statistical Analysis Used: Mann–Whitney U-test and Chi-square tests were used when appropriate to compare the groups. Results: Fifty-seven (32.7% patients attained remission after at least 1 year of thionamide therapy. Of these, 11 (19.2% patients relapsed within 1 year. Age, gender, goiter, and presence of extrathyroidal manifestations were not associated with remission. Higher values of Tc uptake were positively associated with remission (P- 0.02. Time to achievement of normal thyroid function and composite dose: Time scores were significantly associated with remission (P - 0.05 and P - 0.01, respectively. Patients with lower FT4 at presentation had a higher chance of remission (P - 0.01. The relapse rates were lower than previously reported in the literature. A higher Tc uptake was found to be significantly associated with relapse also (P - 0.009. Conclusion: The prognostic factors associated with remission in Graves's disease in this South Indian study are not the same as that reported in Western literature. Tc scintigraphy may have an additional role in identifying people who are likely to undergo remission and thus predict the outcome of Grave's disease.

    A patient-especific method has been used to calculate the therapeutic {sup 1}'3{sup 1} I activity to administer to patients with Graves disease in order to obtain the optimal thyroid dose. The aim of this study was to analyze the dose variation in contrast to the fixed a ctivity regimen. In 30 patients, biokinetic and morfological parameters were estimated from planar scintigraphic images obtained at 4, 24 and 96 hours after injection of {sup 123} I and {sup 131} I activities were calculated to deliver 120 Gy to the thyroid. Comparative dose calculations were carried out assuming that the individual patients had been treated according to 370 MBq activity administration. Activity (or dose) was reduced by an average factor of 2.4 and up to a factor 4.9 for an individual patient. The implemen ted method seeks a balance among the accuracy of the calculations, resource consumption and patient comfort. (Author)

    We analyzed the performance of the Irikura and Miyake (Pure and Applied Geophysics 168(2011):85-104, 2011) (IM2011) asperity-based kinematic rupture model generator, as implemented in the hybrid broadband ground motion simulation methodology of Graves and Pitarka (Bulletin of the Seismological Society of America 100(5A):2095-2123, 2010), for simulating ground motion from crustal earthquakes of intermediate size. The primary objective of our study is to investigate the transportability of IM2011 into the framework used by the Southern California Earthquake Center broadband simulation platform. In our analysis, we performed broadband (0-20 Hz) ground motion simulations for a suite of M6.7 crustal scenario earthquakes in a hard rock seismic velocity structure using rupture models produced with both IM2011 and the rupture generation method of Graves and Pitarka (Bulletin of the Seismological Society of America, 2016) (GP2016). The level of simulated ground motions for the two approaches compare favorably with median estimates obtained from the 2014 Next Generation Attenuation-West2 Project (NGA-West2) ground motion prediction equations (GMPEs) over the frequency band 0.1-10 Hz and for distances out to 22 km from the fault. We also found that, compared to GP2016, IM2011 generates ground motion with larger variability, particularly at near-fault distances (1 s). For this specific scenario, the largest systematic difference in ground motion level for the two approaches occurs in the period band 1-3 s where the IM2011 motions are about 20-30% lower than those for GP2016. We found that increasing the rupture speed by 20% on the asperities in IM2011 produced ground motions in the 1-3 s bandwidth that are in much closer agreement with the GMPE medians and similar to those obtained with GP2016. The potential implications of this modification for other rupture mechanisms and magnitudes are not yet fully understood, and this topic is the subject of ongoing study. We concluded

    Full Text Available Graves' disease is a thyroid-specific autoimmune disorder in which the body makes antibodies to the thyroid-stimulating hormone receptor leading to hyperthyroidism. Therapeutic options for the treatment of Graves' disease include medication, radioactive iodine ablation, and surgery. Radioactive iodine is absolutely contraindicated in pregnancy as exposure to I-131 to the fetal thyroid can result in fetal hypothyroidism and cretinism. Here we describe a case of a female patient with recurrent Graves' disease, who inadvertently received I-131 therapy when she was estimated to be eight days pregnant. This was despite the obtaining of a negative history of pregnancy and a negative urine pregnancy test less than 24 hours prior to ablation. At birth, the infant was found to have neonatal Graves' disease. The neonatal Graves' disease resolved spontaneously. It was suspected that the fetal thyroid did not trap any I-131 as it does not concentrate iodine until 10 weeks of gestation.

    Full Text Available A atenção integral em saúde mental é um desafio para os serviços de saúde, sobretudo no que diz respeito ao acompanhamento não psiquiátrico. O objetivo deste artigo é apresentar uma revisão bibliográfica acerca do atendimento ofertado ao paciente com transtorno mental grave, internado no hospital geral devido a complicações clínico-cirúrgicas. Como resultado, verifica-se que as publicações, ainda que escassas, indicam que o louco é considerado perigoso, violento e imprevisível. Assim, conclui-se que não basta criar no hospital geral leitos de atenção integral a pacientes com transtorno mental sem que se promova espaços de elaboração das representações negativas associadas à loucura.

    2015-01-01

    Warthin-like Papillary thyroid carcinoma (WPTC) is a rare variant of papillary carcinoma of thyroid, PTC which derives its name by closely resembling Warthin's tumor of salivary gland. Hallmark histological feature of this variant is papillary folding lined by oncocytic neoplastic cells with clear nuclei and nuclear pseudoinclusions, accompanied by prominent lymphocytic infiltrate in the papillary stalks. It is thought to be one of those differentiated thyroid cancers with favorable prognosis. We report a case of Graves' disease with a cold nodule harboring WPTC with initial presentation of lymph nodal metastases. It is important to identify this peculiar variant of PTC as 5 to 10% of them undergo dedifferentiation and 30% have the lymph nodal metastases and extra thyroidal extension.

    Based on experience from the treatment of other autoimmune diseases and because of the limitations imposed by existing therapeutic options for Graves' disease (GD) and thyroid-associated ophthalmopathy (TAO), rituximab (RTX) was recently proposed as a novel therapy option. Here, we summarize...... the rationale for using RTX; give an overview of the possible mechanisms of action; and give an account of its effects and side-effects when used in GD and TAO. Scant evidence, originating from only a few methodologically inhomogeneous studies, suggests that RTX may prolong remission for hyperthyroidism over...... favourably to conventional therapy. It is the first in what is likely to be a series of new and emerging treatments specifically targeting relevant components of the immune system. Further studies will hopefully lead to improved and better tailored, individualized therapy for GD and especially TAO....

    This paper presents the results of TL and OSL dating of soil and fragments of bricks from a grave, which was occupied by two mummified nuns, found at 'Luz' Monastery, located in the state of Sao Paulo, Brazil. The TL and OSL ages were compared to C-14 dating ones obtained from bone collagens of the mummies. The majority of the ages is related to the eighteenth century. The gamma-ray spectroscopy was used to evaluate natural radioisotope concentrations in the samples, and by using these concentrations the annual dose rates, from 3.0 to 5.3 Gy/kyr, were obtained. Neutron activation analysis was performed and the radioisotope contents results are in agreement with those obtained by gamma-ray spectroscopy. The contents of U, Th and Ce elements were higher than those found in usual sediments. (author)

    Objective To investigate changes in T lymphocyte subsets and NK cells in patients with simple Graves' disease (GD)and Graves' disease combined with type 2 diabetes mellitus (GD/T2DM). Methods Fifteen cases of GD/ T2DM were selected from our hospital from November 2001 to November 2004. Before and after therapy thyroid function, thyroglobulin antibody (TGA), thyroid microsomal antibody (TMA) and blood glucose level were measured, and T lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) and NK cells (CD56) were measured by immunofluorescence double labeling monoclonal antibody and flow cytometry, respectively. At the same time, comparison was made with simple GD (15 cases), T2DM (15 cases) and healthy control (20 cases). Results Before therapy, CD4/CD8, CD4 and NK cells in GD/T2DM were less than normal, and there was no significant difference in comparison with simple GD (P<0.05). In T2DM group, only CD4/CD8 and CD4 were less than those of healthy controls (P<0.05). When thyroid function recovered after 1 to 3 months of methimazole treatment in both GD/T2DM and simple GD groups, various indexes recovered, which were more obvious in simple GD. Conclusion Immune hypofunction of GD may be the key to the immune abnormality of GD/T2DM, which is more significant than that of simple GD or T2DM. The recovery of thyroid function and immune abnormality is not consistent, and the recovery of GD is more significant than that of GD/T2DM.

    Full Text Available El linfedema puede afectar a cualquier parte del cuerpo, incluido el escroto y el pene. Esta alteración en el drenaje linfático provoca en ocasiones grandes deformidades que conocemos como elefantiasis. El linfedema genital causa graves limitaciones funcionales y emocionales en los pacientes que lo padecen, pues a menudo sufren dolor debido a la irritación crónica, infecciones recurrentes, incapacidad para asearse, disfunción sexual, deformidad estética, llegando incluso a limitar la movilidad o la deambulación. No existe un tratamiento médico o quirúrgico ideal para el linfedema genital masculino. En la literatura se hace referencia a colgajos fasciocutáneos de la cara interna de los muslos tras grandes resecciones de tejido escrotal, pero este tipo de cirugía altera la termorregulación testicular y puede producir esterilidad. También está descrito el uso de injertos laminares de piel, que no aportan una cobertura estable. Otra opción es la reconstrucción con colgajos perineales posteriores, que preservan los linfáticos perirrectales para proveer un drenaje linfático adecuado a la zona. Presentamos 2 casos de linfedema escrotal grave, elefantiásico, no infeccioso, en los cuales realizamos linfangiectomía, resección de todo el tejido linfedematoso y reconstrucción con colgajos perineales locales. En ambos pacientes los resultados fueron satisfactorios, mejorando significativamente su calidad de vida sin evidenciar signos de recurrencia 1 año después del tratamiento.

    Orbital fibroblast differentiation to adipocytes is a peroxisome proliferator-activated receptor g (PPARg)-dependent process essential for pathogenic tissue remodeling in Graves' orbitopathy (GO). PPARg2 Pro¹²Ala polymorphism modulates expression and/or function of the molecule encoded by this gene and is a promising locus of GO. Here, we analyzed associations of PPARg2 Pro¹²Ala with clinical manifestation of GO in 742 Polish Caucasians including 276 Graves' disease (GD) patients. In our study, the Ala¹² allele and Ala¹² variant (Ala¹²Ala and/or Pro¹²Ala genotype) decreased the risk of GO (p = 0.000012 and p = 0.00013). Moreover, Ala¹²Ala genotype was observed only in patients without GO (p = 0.002). GD patients with Ala¹² variant had less active and less severe eye symptoms. Female carriers of the Ala¹² allele rarely developed GO, but the marker was not related to symptoms of GO. The opposite finding was recorded in males, in whom the studied polymorphism was related to activity, but not to the development, of GO. In Ala¹² variant carriers without familial history of thyroid disease, risk of GO was lower than in persons with a familial background. The Ala¹² allele seemed to protect smokers from GO, but in nonsmokers, such a relation was not obvious. A multivariate analysis indicated the Pro¹²Ala marker as an independent risk factor of eye symptoms (p = 0.0001) and lack of Ala increases the risk of GO 3.24-fold. In conclusion, the gain-of-function Ala¹² variant protects against GO and modulates the course of the disease.

    Purpose: To evaluate the efficacy of radiotherapy (RT) with total dose of 20 Gy (RT 20 Gy) in the treatment of Graves' ophthalmopathy. Methods: A systematic review and meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical treatments for Graves' ophthalmopathy. The Medline, Embase, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. Results: A total of 8 randomized controlled trials (439 patients) were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85-250, p=0.04), RT 20 Gy vs sham RT, OR= 3.15 (CI95% 1.59-6.23, p=0.003) and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, p=0.01). There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. Conclusion: Our data have shown that RT 20 Gy should be offered as a valid therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs. (author)

Objetiva ampliar a compreensão do que é o trabalho, mostrando que este vai muito além daquilo que se realiza no mercado. Pretende contribuir para a crítica e transformação da idéia socialmente difundida segundo a qual aquelas pessoas não são capazes de trabalhar. Considera que para o ser humano construir sua própria saúde precisa enfrentar as tentativas de imposições do meio em que está inserido em um dado momento, assim como trabalhar envolve sempre negociar com os elementos que o meio - ambiente e laborativo - apresenta. Conclui que, ao colocar-se em situação de trabalho, a pessoa com transtorno mental grave desenvolve a capacidade de negociar com aquelas tentativas de imposição, construindo assim sua saúde e abandonando uma imagem social e pessoal de incapaz.This paper deals with the role of labor in the human life, especially in the lives of mentally handicapped individuals. In this sense, the paper aims to show the meaning of labor, stating that it goes a lot beyond than what is carried out in the working market. The widely accepted idea that these people are not capable of working is criticized. The paper takes into consideration that a human being needs to struggle to build his own health in order to face the restrictions of the environment, once working demands a constant negotiation presented by the labor and living environments. It is shown that a person with a severe mental disorder develops the ability to overcome the restriction imposed his previous image associated with a social and personal weakness.

    Thyroid uptake of (99m)Tc-pertechnetate is a useful way to determine the cause of thyrotoxicosis. In daily clinical practice, (99m)Tc-pertechnetate uptake is used to discriminate between Graves' disease and painless thyroiditis when clinical information is not enough to make the distinction. However, since the optimal cutoff value of (99m)Tc-pertechnetate uptake has not yet been elucidated, our aim was to determine this value. We recruited patients with thyrotoxicosis in whom (99m)Tc-pertechnetate uptake was measured in clinical settings between 2009 and 2013. Three experienced endocrinologists (who were blinded to the value of (99m)Tc-pertechnetate uptake and initial treatment) diagnosed the cause of thyrotoxicosis based on thyrotropin, free triiodothyronine, free thyroxine, and thyrotropin receptor antibody levels, and by ultrasound findings and using images of thyroid uptake of (99m)Tc-pertechnetate without the actual values. Ninety-four patients diagnosed as having Graves' disease or painless thyroiditis were finally included. According to the diagnosis, the optimal cutoff value of (99m)Tc-pertechnetate uptake was determined by receiver operating characteristics analysis. A cutoff value of 1.0% provided optimal sensitivity and specificity of 96.6% and 97.1%, respectively. Then, its validity was confirmed in 78 patients with confirmed Graves' disease or painless thyroiditis diagnosed at another institute. Applying this cutoff value to the patients with thyrotoxicosis revealed positive and negative predictive values for Graves' disease of 100% and 88.9%, respectively. In conclusion, a cutoff value for (99m)Tc-pertechnetate uptake of 1.0% was useful to discriminate between Graves' disease and painless thyroiditis.

  16. Exceptional hyperthyroidism and a role for both major histocompatibility class I and class II genes in a murine model of Graves' disease.

    Directory of Open Access Journals (Sweden)

    Sandra M McLachlan

    Full Text Available Autoimmune hyperthyroidism, Graves' disease, can be induced by immunizing susceptible strains of mice with adenovirus encoding the human thyrotropin receptor (TSHR or its A-subunit. Studies in two small families of recombinant inbred strains showed that susceptibility to developing TSHR antibodies (measured by TSH binding inhibition, TBI was linked to the MHC region whereas genes on different chromosomes contributed to hyperthyroidism. We have now investigated TSHR antibody production and hyperthyroidism induced by TSHR A-subunit adenovirus immunization of a larger family of strains (26 of the AXB and BXA strains. Analysis of the combined AXB and BXA families provided unexpected insight into several aspects of Graves' disease. First, extreme thyroid hyperplasia and hyperthyroidism in one remarkable strain, BXA13, reflected an inability to generate non-functional TSHR antibodies measured by ELISA. Although neutral TSHR antibodies have been detected in Graves' sera, pathogenic, functional TSHR antibodies in Graves' patients are undetectable by ELISA. Therefore, this strain immunized with A-subunit-adenovirus that generates only functional TSHR antibodies may provide an improved model for studies of induced Graves' disease. Second, our combined analysis of linkage data from this and previous work strengthens the evidence that gene variants in the immunoglobulin heavy chain V region contribute to generating thyroid stimulating antibodies. Third, a broad region that encompasses the MHC region on mouse chromosome 17 is linked to the development of TSHR antibodies (measured by TBI. Most importantly, unlike other strains, TBI linkage in the AXB and BXA families to MHC class I and class II genes provides an explanation for the unresolved class I/class II difference in humans.

They were monitored with ophthalmologic assessment (clinical activity score-CAS and magnetic resonance imaging, using a signal intensity ratio (SIR of the recti muscles in comparison to the cerebral substantia alba. RESULTS: Amelioration of CAS was seen in 68% of the orbits in both groups. SIR also had a significant reduction after treatment: the initial median of 1.14 in G1 and 1.27 in G2, evolved, after treatment, to 1.07 in G1 and 0.69 in G2. The variation between both groups after treatment was not significant (p=0.22. None of the patients treated with colchicine had side effects; on the other hand, side effects in G2 were weight gain, edema, gastric complaints, hirsutism, weakness, depression, and alterations in blood pressure. CONCLUSION: Colchicine had a beneficial effect on the inflammatory phase of GO without the side effects of prednisone.OBJETIVO: Investigar se a colchicina é eficaz no tratamento da oftalmopatia de Graves, nós comparamos o seu efeito com a prednisona em 22 pacientes tratados na fase inflamatória da doença.

    Full Text Available Las enfermedades tiroideas autoinmunes (ETA son los desórdenes más frecuentes que llevan a la disfunción de la glándula tiroidea. Incluyen varias formas clínicas como Tiroiditis de Hashimoto (TH y Enfermedad de Graves (EG. La relación entre TH y EG ha sido objeto de debate por décadas. Si bien, muy diferentes en su clínica, algunos las consideran los lados opuestos de una misma moneda. En su patogénesis tienen aspectos en común, como la predisposición genética demostrado por la ocurrencia en una misma familia y en un mismo individuo. Sin embargo, diferencias en el microambiente local determinan la diferente expresión fenotípica o el viraje de una a otra patología. El objetivo de esta monografía es investigar similitudes y diferencias entre TH y EG en las distintas etapas que llevan al desarrollo de autoinmunidad. Los autores declaran no poseer conflictos de interés.Autoimmune thyroid disease (ATD is the most common disorder that leads to thyroid gland dysfunction. ATD manifests in various clinical forms, such as Hashimoto's Thyroiditis (HT and Graves' Disease (GD. The relation between HT and GD has been discussed for decades. Even if they greatly differ in their clinical features and treatment, some people believe they are the opposite sides of the same coin. In their pathogenesis, they share some mechanisms, such as genetic susceptibility, shown by the fact that they tend to occur both in the same person and within the same family. However, differences in the local micro-environment can determine the distinct phenotypic expression or the switch from one disease to the other. The aim of this monograph was to investigate similarities and differences between HT and GD at the diverse stages leading to the development of autoimmunity. No financial conflicts of interest exist.

    The study was performed under the auspices of the International Atomic Energy Commission, Vienna, Austria, with the aim of determining the optimal minimum therapeutic dose of iodine-131 for Graves' disease. The study was designed as a single-blinded randomised prospective outcome trial. Fifty-eight patients were enrolled, consisting of 50 females and 8 males aged from 17 to 75 years. Each patient was investigated by clinical assessment, biochemical and immunological assessment, thyroid ultrasound, technetium-99m thyroid scintigraphy and 24-h thyroid {sup 131}I uptake. Patients were then randomised into two treatment groups, one receiving 60 Gy and the other receiving 90 Gy thyroid tissue absorbed dose of radioiodine. The end-point markers were clinical and biochemical response to treatment. The median follow-up period was 37.5 months (range, 24-48 months). Among the 57 patients who completed final follow-up, a euthyroid state was achieved in 26 patients (46%), 27 patients (47%) were rendered hypothyroid and four patients (7%) remained hyperthyroid. Thirty-four patients (60%) remained hyperthyroid at 6 months after the initial radioiodine dose (median dose 126 MBq), and a total of 21 patients required additional radioiodine therapy (median total dose 640 MBq; range 370-1,485 MBq). At 6-month follow-up, of the 29 patients who received a thyroid tissue dose of 90 Gy, 17 (59%) remained hyperthyroid. By comparison, of the 28 patients who received a thyroid tissue dose of 60 Gy, 17 (61%) remained hyperthyroid. No significant difference in treatment response was found (P=0.881). At 6 months, five patients in the 90-Gy group were hypothyroid, compared to two patients in the 60-Gy group (P=0.246). Overall at 6 months, non-responders to low-dose therapy had a significantly larger thyroid gland mass (respective means: 35.9 ml vs 21.9 ml) and significantly higher levels of serum thyroglobulin (respective means: 597.6 {mu}g/l vs 96.9 {mu}g/l).

Furthermore, the interaction between rs1990760 polymorphism with human leukocyte antigen (HLA risk haplotype DQ2(DQA*0501-DQB*0201, the risk haplotypes DQ2/DQ8 (DQA*0301-DQB*0302 and the status of thyroglobulin antibody (TgAb, thyroid peroxidase antibody (TPOAb and TSH receptor antibody (TRAb in patients and families were analysed. Results No significant differences were found between the allele and genotype frequencies for rs1990760 IFIH1 polymorphism in patients with GD, HT, AD and HC. Also no differences were observed when stratifying the IFIH1 rs1990760 polymorphism for gender, presence or absence of thyroid antibodies (GD:TRAb and HT:TPOAb/TgAb and HLA risk haplotypes (DQ2:for GD and HT, DQ2/DQ8:for AD. Furthermore the transmission analysis in GD and HT families revealed no differences in alleles transmission for rs1990760 IFIH1 from parents with or without HLA risk haplotype DQ2 to the affected offspring. In contrast, by dividing the HT parents according to the presence or absence of thyroid Ab titers, mothers and fathers both positive for TPOAb/TgAb overtransmitted the allele A of IFIH1 rs1990760 to their HT affected offspring (61.8% vs 38.2%;p = 0

    Full Text Available A tuberculose é uma doença curável que pode evoluir para formas graves com necessidade de tratamento dos pacientes em UTI, especialmente se essa não for diagnosticada em tempo ou se afetar pacientes idosos, aqueles em diálise e aqueles com infecção pelo HIV ou outros estados de imunossupressão, assim como nos casos de doença multirresistente. O conhecimento da apresentação radiológica dos casos pode auxiliar no diagnóstico dessas formas graves, assim como a introdução de novos testes, como a detecção rápida do agente por PCR e a TC de tórax, favorecendo o início precoce do tratamento. Além disso, o uso de esquemas sem isoniazida e rifampicina, a absorção entérica incerta e as baixas concentrações séricas das drogas antituberculose podem contribuir para a diminuição da eficácia do tratamento. O prognóstico desses pacientes geralmente é ruim, com elevadas taxas de mortalidade.Tuberculosis is a curable disease that can evolve to severe forms, requiring the treatment of the patients in an ICU, especially if there is a delay in the diagnosis or if it affects elderly patients, those on dialysis, or those with HIV infection or other states of immunosuppression, as well as in cases of multidrug resistant disease. Knowledge of the radiological presentation of the cases can help diagnose these severe forms, as can the introduction of new tests, such as the early detection of the etiological agent by PCR and chest CT, which favors the early initiation of treatment. In addition, the use of regimens without isoniazid and rifampin, as well as uncertain enteral absorption and low serum concentrations of antituberculosis drugs, can reduce the efficacy of treatment. For such patients, the prognosis is generally poor and mortality rates are high.

    Full Text Available The present paper reports the long-term use of clozapine in a prospective sample of 46 chronic schizophrenics. In six months, 21 subjects had been excluded for a number of reasons. In four of them the reasons for exclusion were related to lack of response or adverse effects. The median daily clozapine dose was 400 mg in the remaining 25 patients. As a whole, there were remarkable improvements in core dimensions of psychopathology, global cognitive status, and level of functioning. We confirmed that clozapine is effective in a subgroup of schizophrenics with the severest forms of the disease. If tolerated after the first few months it leads to progressive gains in several domains of behavior. Clozapine should be tried in every patient with schizophrenia in whom positive symptoms, disorganization, or bizarre behavior are a matter of incapacitation despite efforts to keep them under control with other drugs.O presente estudo, prospectivo, relata o uso de longo-prazo da clozapina em 46 esquizofrênicos graves, com mais de cinco anos de doença. Com seis meses de uso da droga, 21 indivíduos haviam sido excluídos por diversas razões. Em quatro, a exclusão se deveu a efeitos adversos ou ausência de resposta. A dose mediana de clozapina foi de 400 mg nos demais 25 pacientes. No todo, observamos melhora em dimensões de psicopatologia, estado cognitivo global, e nível funcional. Concluímos que a clozapina é eficaz em um subgrupo de esquizofrênicos com formas graves da doença. Se tolerada depois dos primeiros meses, produz benefícios progressivos em diversos domínios do comportamento. Clozapina deve ser tentada em todo paciente com esquizofrenia incapacitado por sintomas positivos, desorganização, e/ou comportamentos bizarros, que persistem a despeito de esforços para mantê-los sob controle com outras drogas.

    The treatment options for the hyperthyroidism of Graves' disease are antithyroid drugs, surgery and radioiodine, none of which is considered ideal, as they do not act directly on the etiopathogenesis of the disease. Radioiodine has been increasingly used as the treatment of choice because it is a safe and definitive therapy whose administration is very easy. Some authors prefer to administer higher doses in order to deliberately induce hypothyroidism, while others recommend lower doses that result in a lower incidence of hypothyroidism and a greater incidence of euthyroidism. There is no consensus for the optimal regimen of fixed doses to be used and this is the main focus of the present study, where doses of 10 and 15 mCi of {sup 131}I were compared. Among the 164 patients analyzed, 61 (37.2%) were submitted to 10 mCi and 103 (62.8%) to 15 mCi. In the longitudinal analysis it was observed that remission of the hyperthyroidism was statistically different in the sixth month (p < 0.001), being higher in the group that used the dose of 15 mCi, but similar in both groups at 12 and 24 months. It may be concluded that the administration of fixed doses of 10 and 15 mCi of {sup 131}I brought about a similar remission of the hyperthyroidism after 12 months of treatment. Moreover, the remission rate of the hyperthyroidism had no association with age, sex or previous therapy with antithyroid drugs. (author)

Historically the species has been collected at only 5 localities and all of these are currently threatened by human activities. The scarce number of individuals per population and its narrow geographic distribution contribute to this species being critically endangered, and it is urgent to carry out activities to help it escape extinction.

    The outcome of {sup 131}I therapy for 109 patients with Graves' disease was analysed according to pretreatment laboratory data including thyrotropin receptor antibody (TRAb) activities. Forty-five percent of patients became euthyroid, and 13% of patients became hypothyroid within one year after {sup 131}I therapy. Forty-two percent of patients remained hyperthyroid one year after {sup 131}I therapy. Pretreatment values for serum T{sub 4}, T{sub 3}, and the estimated weight of the thyroid were significantly higher in the hyperthyroid group. The mean for the TRAb index of the hyperthyroid group was significantly higher than that of the euthyroid group. Life table analysis revealed a significant effect of the TRAb index on the rate of hyperthyroidism after 3 months or later. These results appear to suggest that the TRAb index is one of the factors which influence the outcome of {sup 131}I therapy for Graves' disease. (author).

    A 40-year-old woman was admitted due to an urticarial rash that was attributed to recent onset of methimazole treatment for a diagnosis of Grave's disease. The patient had no prior significant medical history and used no medications, including over-the-counter or herbal medications. Her sister had Grave's disease. On admission, the patient received corticosteroids with improvement in her rash. On the second day of the hospitalization, the patient complained of abdominal discomfort. Abdominal ultrasound revealed a large amount of new onset ascites. Peritoneal tap yielded a milky fluid with high triglyceride level (12.2 mmol/L or 1080 mg/dL), consistent with chylous ascites. After discontinuation of the methimazole, the ascites disappeared. The patient later underwent therapeutic thyroidectomy, after which all features of thyrotoxicosis had improved. PMID:26366308

    Full Text Available La mayoría de los pacientes con derrame pericárdico crónico son mujeres y mayores de 50 años. En esta presentación se describe el caso de una paciente de 63 años con derrame pericárdico crónico grave, con antecedente de carcinoma de mama izquierda irradiado, diagnóstico presuntivo no confirmado de tuberculosis pulmonar e hipotiroidea sustituida. Ante la recurrencia del derrame luego de pericardiocentesis y el fracaso del tratamiento antiinflamatorio con AINE se decidió realizar una ventana pericárdica percutánea, sin que se presentaran complicaciones técnicas. Se inició tratamiento con colchicina y se evaluaron las posibles causas: tuberculosa, oncológica, secundaria a hipotiroidismo o por radiación. Por exclusión se llegó a la etiología radiante. Al mes de la realización de la ventana pericárdica no se observaba derrame pericárdico en el ecocardiograma.

    Full Text Available Apresentamos pesquisa avaliativa qualitativa sobre modos de morar de pessoas com transtorno mental grave, vinculadas às redes municipais de saúde mental de três cidades de grande porte. Realizamos observação participante de dez moradores e respectivos cuidadores de Serviços Residenciais Terapêuticos (SRT e acompanhamos o cotidiano de oito usuários de Centros de Atenção Psicossocial (CAPS que constituíram suas moradias por iniciativas próprias. Os moradores e usuários também foram entrevistados em profundidade. O material de campo foi analisado, segundo o método interpretativo, da perspectiva de arquitetos, antropólogos, psicanalistas e sanitaristas. Os resultados apontam carência de processos sistemáticos de reabilitação psicossocial dos moradores de SRT e despreparo dos cuidadores para lidarem com a complexidade de demandas para seu acompanhamento, além de baixo envolvimento dos CAPS com os SRT. Por outro lado, usuários ligados aos CAPS, que não moram em SRT, apresentaram criativa diversidade nos modos de constituir suas moradias e maior interação com a comunidade, embora alguns contem com o apoio de albergues e asilos para resolver suas necessidades. Algumas direções para a superação dos problemas encontrados são apontadas ao final do texto.

    Full Text Available O penfigoide de membranas mucosas é entidade nosológica encarada como um fenótipo, que engloba várias dermatoses autoimunes com lesões bolhosas subepidérmicas, ocorrendo predominantemente nas membranas mucosas, com êxito cicatricial. O acometimento esofágico no penfigoide de membranas mucosas é raro e observado em pacientes com lesão disseminada. As alterações mais comuns são múltiplas membranas ou constrições esofagianas. No presente relato, os autores apresentam paciente com PMM sem lesões cutâneas e estenose esofágica grave, que entrou em remissão após uso de imunoglobulina venosaMucous membrane pemphigoid (MMP is a rare nosological entity. MMP consists of a clinical phenotype in which several autoimmune subepidermal bullous diseases are classified. It occurs predominantly in the mucous membranes and usually results in scarring. Esophageal involvement in MMP is rare and is generally seen in patients in whom lesions are widespread. The most common alterations are multiple esophageal membranes or strictures. In the present case, the authors report on a patient with MMP without any skin lesions and with severe esophageal strictures who went into remission following use of intravenous immunoglobulin
