    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. PMID:27059986

    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.

  6. Prevention of Graves' ophthalmopathy.

    Smoking is the most important risk factor for the occurrence/progression of Graves' ophthalmopathy (GO), as well as for its lower/slower response to immunosuppression. Accordingly, refrain from smoking should be urged, both as primary prevention (removal of risk factors in Graves' patients without GO), secondary prevention (early detection and treatment of asymptomatic/very mild GO) and tertiary prevention (reduction of complications/disability of overt GO). A 6-month course of 200 μg/day sodium selenite can prevent progression of mild GO to more severe GO and is, therefore, a form of secondary prevention and, probably, primary prevention. Correction of thyroid dysfunction and stable maintenance of euthyroidism are important preventive measures. The optimal treatment for hyperthyroidism in patients with GO is uncertain, because evidence demonstrating the superiority of antithyroid drugs over thyroid ablation (radioiodine, thyroidectomy, or both) is lacking. If radioiodine is used, low-dose steroid prophylaxis is recommended, particularly in smokers, to prevent radioiodine-associated GO progression. PMID:22632372

    Neuroimaging of Graves' orbitopathy (GO) plays an important role in the differential diagnosis and interdisciplinary management of patients with GO. Orbital imaging is required in unclear or asymmetric proptosis, in suspected optic neuropathy and prior to decompression surgery. Especially computed tomography and magnetic resonance (MR) imaging show the actual objective morphological findings, quantitative MR imaging giving additional information concerning the acuteness or chronicity of the disease. Major morphological diagnostic criteria include a spindle like spreading of the rectus muscles without involvement of the tendon, a compression of the optic nerve in the orbital apex (crowded orbital apex syndrome) and the absence of any space occupying intraorbital process. A longer lasting course of the disease may lead to a corresponding impression of the lamina papyracae, the normally parallel configured medial wall of the orbit, similar to a spontaneous decompression.

  8. Hashimoto's thyroiditis following Graves' disease.

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment. PMID:20305330

    Excavation of mock graves in sediments of aeolian and fluvial origin were conducted to test the bleaching efficiency of grave digging in materials that commonly host ancient burials in Australia. Grave-size pits were dug into Pleistocene aeolian sediments at Willandra Lakes and younger fluvial sediments on the Lachlan River, backfilled, and re-excavated. Samples for optical dating were taken from sediment infilling the mock graves and from the adjacent, undisturbed substrate, and analysed using the single aliquot-regenerative dose (SAR) protocol applied to single quartz grains. The resulting equivalent dose (De) distributions revealed that ≤1% of grains had been fully zeroed in both settings, and an additional 1-6% of poorly bleached grains were apparent in the fluvial sediments. Insufficient and heterogeneous bleaching of sediments during excavation and backfilling produced a decrease in the central dose of between 3 and 6 Gy, and an increase in over-dispersion values of between 5 and 10%. These differences were insufficient to clearly distinguish the disturbance event from the effects of bioturbation, biological mixing, or other sources of De variation. The use of the Minimum Age Model substantially over-estimated the burial age (zero years) in both depositional environments, with the degree of over-estimation increasing with the age of the host sediments. These results suggest that optically stimulated luminescence (OSL) techniques will not produce accurate ages for grave infill in a number of forensic and archaeological settings. Further study of the bleaching susceptibility of grains within grave infills, as well as the effectiveness of grave-digging as a bleaching mechanism is required. In other archaeological and geomorphological applications of OSL dating we recommend routine checks on the effective zeroing of sediments in modern equivalent situations. PMID:24953668

    The aims of surgical treatment in Graves's orbitopathy (GO) are improvement of function and appearance. Since antiinflammatory treatment of GO rarely results in a complete resolution of symptoms, surgical treatment is very important for patients well being. Rehabilitative surgery includes orbital decompression, squint correction, lid lengthening and blepharoplasty and these procedures have to be performed in centres of expertise. Various techniques have been developed for orbital decompression which allow now a graded approach to proptosis reduction and optic nerve decompression in emergency situations. Extraocular muscle recessions can be successfully performed to treat most of the patients with diplopia. Only large or complex squint angles are difficult to treat and step by step procedures are recommended in these patients. Lid lengthening procedures are performed most often in GO patients and should be performed under local anaesthesia to get a good result. Serious complications are rare. PMID:22632370

    In this review we have described the rationale for the appropriate treatment of patients with Graves' disease. Because the etiology of this disorder remains obscure, its management remains controversial. Since antithyroid drugs and radioiodine became readily available in the early 1950s, they have been widely used for the treatment of thyrotoxicosis, and the number of cases treated surgically has markedly decreased. However, almost four decades of experience have disclosed an unexpectedly high incidence of delayed hypothyroidism after radioiodine treatment and a low remission rate after antithyroid therapy. As a result, surgery is again being advocated as the treatment of choice. The three modalities of treatment have different advantages and disadvantages, and selection of treatment is of importance. In principle, we believe that for most patients a subtotal thyroidectomy should be performed after the patient has been rendered euthyroid by antithyroid drugs. We attempt to leave a thyroid remnant of 6 to 8 gm.36 references.

    We used radiation therapy (a total of 2,000 rads) to treat 14 patients (three men and 11 women, ranging in age from 27 to 72 years) with Graves' disease. Three of these patients had refused to take corticosteroids and the other 11 had failed to respond to them, had experienced side effects, or had other contraindications to their use. After follow-up periods ranging from six months to three years, soft-tissue inflammation was reduced in 13 of the 14 patients. All but two patients showed a decrease in proptosis of 1 to 3 mm. Myopathy showed the least improvement. Although we noted transient eyelid erythema, there were no permanent sequelae and none of the patients has had a recurrence of the inflammation.

    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. PMID:26876268

    The medical treatment of Graves' orbitopathy (GO) is usually reserved to moderate to severe disease. Steroids have been widely employed and possess anti-inflammatory activity, but about 20-30% of patients are not responsive and about 20% present with disease recurrence. Immunosuppressive therapy alternative to corticosteroids may target the different antigens involved in pathogenic mechanisms of GO. Some have already been employed in clinical studies and showed interesting results, although the lack of randomized and controlled trials suggests caution for their use in clinical practice. Potential targets for therapy in GO are the TSH receptor and the IGF-1 receptor on the fibroblasts, inflammatory cytokines, B and T cells. Most promising results are obtained by interacting with the PIK3/mTORC1 signaling cascades for adipogenesis and the anti-IGF-1R with the monoclonal antibody teprotumumab. A recent open study has shown that tocilizumab, an anti-sIL-6R antibody, inactivates GO. Consistent reports on the efficacy of rituximab have recently been challenged by randomized controlled trials. Clinical practice will greatly benefit from the use of disease modifying agents in GO, as compared to steroids, currently standard treatment for GO. Among these, rituximab may be useful, especially in patients resistant to steroid or with contraindications to steroids. However, larger randomized controlled trials are needed for definitive data on the potential disease-modifying role of rituximab in GO. Direct targeting of the orbital fibroblast via immunosuppression or nonimmunosuppressive drugs is emerging as a promising alternative. PMID:26361263

    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. PMID:25727474

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

    Background It is well known that thyrotoxicosis causes rhythm disorders including sinus tachycardia, atrial fibrillation, and atrial flutter. Atrial fibrillation is the most common arrhythmia in thyrotoxicosis, occurring in 5-15% of patients over 60 years of age, whereas ventricular arrhythmia is an unusual manifestation. Case Report An 18-year-old Japanese woman was admitted to our emergency department because of loss of consciousness caused by ventricular fibrillation. She had been diagnosed with Graves' disease only 5 days earlier and had no other past medical history. Blood examination showed no obvious abnormality except thyrotoxicosis, and coronary angiography revealed patent coronary arteries. She was diagnosed with thyroid storm due to Graves' disease and is currently healthy during outpatient follow-up. Conclusion This case highlights that thyrotoxicosis can, albeit extremely rarely, cause ventricular fibrillation even in the absence of hypokalemia or underlying cardiovascular disease.

    The Global Reference Analysis and Visualization Environment (GRAVE) is a research prototype multimedia system that manages a diverse variety of data types and presents them to the user in a format that is geographically referenced ton the surface of a globe. When the user interacts with the globe, the system automatically manages the `level-of-detail' issues to support these user actions (allowing flexible functionality without sacrificing speed or information content). To manage the complexity of the presentation of the (visual) information to the user, data instantiations may be represented in an iconified format. When the icons are picked, or selected, the data `reveal' themselves in their `native' format. Object-oriented programming and data type constructs were employed, allowing a single`look and feel' to be presented to the user for the different media types. GRAVE currently supports the following data types: imagery (from various sources of differing resolution, coverage, and projection); elevation data (from DMA and USGS); physical simulation results (atmospherics, geological, hydrologic); video acquisitions; vector data (geographical, political boundaries); and textual reports. GRAVE was developed in the Application Visualization System (AVS) Visual Programming Environment (VPE); as such it is easily modifiable and reconfigurable, supporting the integration of new processing techniques/approaches as they become available or are developed.

    Graves' disease is the most common cause of hyperthyroidism. Clinical features include thyroid enlargement, eye signs, tachycardia, heat intolerance, emotional lability, weight loss, and hyperkinesis. Three modes of therapy are available. The preferences of the patient and physician are usually prime considerations in devising the therapeutic plan. Radioactive iodine is the most frequently used and safest method of treatment for adults. Antithyroid drugs are preferred for children and pregnant women. Surgery is usually reserved for patients in whom the other forms of treatment are not acceptable. Considerable patient education during the decision-making process enhances the success of the therapeutic plan.

    Graves’ orbitopathy (GO) is rare in pediatric patients, however is the most common extrathyroid manifestation of Graves’ disease (GD), being present in 30-67% of patients. GO is an autoimmune inflammatory disorder involving orbital connective and fatty tissues as well as the extraocular muscles. In children, GO is less common and less severe than in adults. The most common symptoms are upper eyelid retraction, conjunctival injection, and proptosis and periorbital edema. Severe complications include dysthyroid optic neuropathy, corneal ulceration and eyeball subluxation. The diagnosis is established by clinical, laboratory and imaging findings. There are no management guidelines for GO in children but adult recommendations include the assessment of clinical activity and its severity, to implement the best treatment. Supportive therapies are intended to relieve symptoms and prevent corneal damage in mild cases. Tobacco exposure should also be avoided. The first line of treatment is systemic administration of corticosteroids in active and severe cases. Other options as somatostatin use and retrobulbar radiation have not been used in children, therefore their use is not recommended. PMID:26436933

    A key issue of Really Significant Genes (RSG) that caused Graves Disease is unresolved. RSGs are considered likely major contributors to genetic risk for a disease. These genes should be strongly linked within families and they could become clinically useful as predictors of disease. Some Graves Disease susceptibility genes have been identified. The first identified was the Human-Leucocyte-Antigen DR (HLA-DR) gene locus, then a non-HLA genes as cytotoxic T lymphocyte antigen (CTLA-4), CD40, protein tyrosine phosphatase-22 (PTPN22), thyroglobulin, and thyroid-stimulating hormone receptor (TSHR) gene. The sites observed in different populations were not always the same. With the completion of the HapMap, which provided the geography of thousands single nucleotide polymorphisms (SNPs), the search of more minor associated genes started again although studies never revealed stronger candidates, meanwhile, the role of the environment in disease development remains poorly understood. The importance of the environment with the mechanisms involved including genetic factors is needed to be decided. PMID:19258680

    To investigate the role of NAMPT/visfatin in euthyroid patients with Graves' disease without (GD) and with Graves' ophthalmopathy (GO), we analyzed NAMPT leukocyte expression and its serum concentration. This was a single-center, cross-sectional study with consecutive enrollment. In total, 149 patients diagnosed with Graves' disease were enrolled in the study. We excluded subjects with hyper- or hypothyroidism, diabetes mellitus, other autoimmune disorders, active neoplastic disease, and infection. The control group was recruited among healthy volunteers adjusted for age, sex, and BMI with normal thyroid function and negative thyroid antibodies. Serum levels of visfatin, TSH, FT4, FT3, antibodies against TSH receptor (TRAb), antithyroperoxidase antibodies, antithyroglobulin antibodies, fasting glucose, and insulin were measured. NAMPT mRNA leukocyte expression was assessed using RT-qPCR. NAMPT/visfatin serum concentration was higher in GD (n = 44) and GO (n = 49) patients than in the control group (n = 40) (p = 0.0275). NAMPT leukocyte expression was higher in patients with GO (n = 30) than in GD patients (n = 27) and the control group (n = 29) (p < 0.0001). Simple linear regression analysis revealed that NAMPT/visfatin serum concentration was significantly associated with GD (β = 1.5723; p = 0.021). When NAMPT leukocyte expression was used as a dependent variable, simple regression analysis found association with TRAb, fasting insulin level, HOMA-IR, GD, and GO. In the stepwise multiple regression analysis, we confirmed the association between higher serum NAMPT/visfatin level and GD (coefficient = 1.5723; p = 0.0212), and between NAMPT leukocyte expression and GO (coefficient = 2.4619; p = 0.0001) and TRAb (coefficient = 0.08742; p = 0.006). Increased NAMPT leukocyte expression in patients with GO might suggest a presently undefined role in the pathogenesis of GO. PMID:26767650

    Background. Due to low incidence of Graves' ophthalmopathy (GO) among children, the manifestation is poorly analyzed, posing a risk to late identification of insidious disease. Purposes. To identify predictive factors that may influence the development of GO in pediatric and young patients with Graves' disease (GD). Methods. A cross-sectional study of patients newly diagnosed with pediatric or juvenile GD during 2002–2012 was conducted at the Hospital of Lithuanian University of Health Sciences. Ocular evaluation was based on European Group on Graves' Orbitopathy survey. The ocular manifestations were analyzed in relation to demographic, environmental, and clinical factors. Results. In total, 130 patients with juvenile GD were included; 29.2% had GO. Median age at GD onset was 17 yrs (IQR 4–29). Main symptoms of GO were eyelids retraction (73.7%), proptosis (65.8%), injection of conjunctiva (42.1%), and eyeball motility disturbance (21.1%). Major significant and independent risk factors for GO development were high initial concentration of FT4 (OR = 5.963), TTHAb (OR = 6.358), stress (OR = 6.030), and smoking (OR = 7.098). Conclusion. The major factors that could influence GO development were smoking, stress, and increased levels of initial TRAb, FT4. Slight proptosis, retraction of eyelids, and conjunctive injection were found as predominant ophthalmological symptoms in juvenile GO. PMID:27413373

    The objective of this report is to present a case of Graves' thyrotoxicosis-induced cardiomyopathy. This is a case of a 26 year old woman that presented with severe symptomatic congestive heart failure and was subsequently diagnosed with dilated cardiomyopathy secondary to Graves' disease. Despite an initial left ventricular systolic ejection fraction of 20% on echocardiography, treatment with anti-thyroid agents led to rapid improvement of her clinical status and normalization of her ejection fraction. The proposed mechanisms underlying the development of systolic dysfunction in thyrotoxicosis are discussed and the literature on similar cases previously reported is highlighted. Cardiomyopathy should be considered even in young patients with Graves' thyrotoxicosis. PMID:23645990

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

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

    Chronic urticaria is a common condition characterized by recurrent episodes of mast cell-driven wheal and flare-type skin reactions lasting for more than 6 weeks. In about 75% of cases, the underlying causes remain unknown, and the term chronic idiopathic urticaria (CIU) is used to emphasize that wheals develop independently of identified external stimuli. Although CIU affects about 1.0% of the general population, its etiopathogenesis is not yet well understood. It is now widely accepted that in many cases CIU should be regarded as an autoimmune disorder caused by circulating and functionally active IgG autoantibodies specific for the IgE receptor (FceRI) present on mast cells and basophils or for IgE itself. The well-known association of CIU with other autoimmune processes/diseases represents further indirect evidence of its autoimmune origin. Autoimmune thyroid diseases, especially autoimmune thyroiditis, represent the most frequently investigated diseases in association with CIU. Here we review this topic with particular regard to the association between Graves' disease and CIU. The possible pathogenetic mechanisms and the clinical implications of such an association are discussed. PMID:23609949

    A suspected old royal cemetery has been surveyed at the Kwame Nkrumah University of Science and Technology (KNUST) campus, Kumasi, Ghana using Electrical Resistivity Tomography (ERT) with the objective of detecting graves in order to make informed decisions with regard to the future use of the area. The survey was conducted on a 10,000 m2 area. Continuous Vertical Electrical Sounding (CVES) was combined with the roll along technique for 51 profiles with 1 m probe separation separated by 2 m. Inverted data results indicated wide resistivity variations ranging between 9.34 Ωm and 600 Ωm in the near surface. Such heterogeneity suggests a disturbance of the soil at this level. Both high (≥ 600 Ωm) and low resistivity (≤ 74.7 Ωm) anomalies, relative to background levels, were identified within the first 4 m of the subsurface. These were suspected to be burial tombs because of their rectangular geometries and resistivity contrasts. The results were validated with forward numerical modeling results. The study area is therefore an old cemetery and should be preserved as a cultural heritage site.

    Fusobacterium necrophorum is the causative agent in the pharyngitis. After invasion of the oropharyngeal mucosa by the organism leads to the development of the grave complications like superficial thrombophlebitis of internal jugular vein, septic emboli in the lung and coagulopathy. A 23-year-old male presented with chief complaints of sore throat, headache and high grade fever with past history of upper respiratory tract infection one month ago. On examination, he had high grade fever, tachycardia, hypotension and tender cervical lymph nodes. Oropharyngeal mucosa appeared ooedematous and congested. Leucocytosis with raised ESR was present. Blood culture positive for Fusobacterium necrophorum. Dilated right IJV with the hypoechoic thrombosis seen on Ultrasonography & Doppler. Patient was diagnosed as a case of Lemierre syndrome secondary to oropharyngeal infection was made. He was treated with intravenous imipenem and metronidazole, and then shifted to oral amoxicillin. After completion of full course of the therapy of 6 weeks, patient was improved clinically and all routine blood investigations were normalized. Blood culture was negative for Fusobacterium necrophorum. No evidence of thrombosis within the right internal jugular vein on Doppler. PMID:26266187

    The Energy Resources Program of the U.S. Geological Survey promotes and supports coal research to improve the understanding of the coal endowment of the United States. This results in geologically based, non-biased energy information products for policy and decision makers, land and resource managers, other federal and state agencies, the domestic energy industry, foreign governments, nongovernmental groups, academia, and other scientists. A more integrated approach to our coal quality work involves what we call a 'cradle to grave' approach. These types of studies focus not on just one aspect of the coal but rather on how or where different quality parameters form and (or) occur and what happens to them through the mining, production, transport, utilization and waste disposal process. An extensive suite of coal quality analyses, mineralogical, petrology, and leaching investigations are determined on samples taken from the different phases of the coal utilization process. This report consists of a tutorial that was given on June 10, 2007 at the 32nd International Technical Conference on Coal Utilization & Fuel Systems, The Power of Coal, Clearwater Coal Conference in Clearwater, Florida, USA. This tutorial covers how these studies are conducted and the importance of providing improved, comprehensive, science-based data sets for policy and decision makers.

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

    A distinct clinical entity of uveitis associated with human T lymphotropic virus type 1 (HTLV-I) has been reported previously. During the period between January 1989 and April 1992, 93 patients were observed with HTLV-I uveitis and a significant correlation was found between Graves' disease and HTLV-I uveitis. Sixteen of the 93 patients with HTLV-I uveitis (17.2%) had a previous history of Graves' disease. Fifteen patients were female (15/60, 25.0%) and one was male (1/33, 3.0%). Interestingly, uveitis occurred after the onset of Graves' disease in all cases. On the other hand, none of 222 patients with idiopathic uveitis who were seronegative to HTLV-I had a history of Graves' disease. Although the mechanisms by which HTLV-I causes the correlation between uveitis and Graves' disease are unknown, the present data suggest that immune mediated or autoimmune mechanisms are involved in HTLV-I uveitis.

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

    The most common etiologic cause of thyrotoxicosis in children and adults is autoimmune Graves' (Basedow's) disease. Antithyroid medications, surgery and radioactive iodine have been used in the treatment of Graves' hyperthyroidism for more than six decades. The use of antithyroid drugs is the most common therapeutic approach. However, long-term remission with antithyroid drugs can be expected in 20-50% of adults and 20-30% of children. The methods for definitive treatment of Graves' hyperthyroidism are iodine-131 (radioiodine) and surgery. Both treatment modalities have benefits and risks and the decision is made according to the age, patient preference and the presence of other co-morbidities, individual characteristics of patients and the availability of certain treatment modality. Radioiodine is simple, safe, effective and economic procedure for definitive treatment of Graves' hyperthyroidism. It is administered ambulatory and can be given to the patient in thyrotoxicosis. Due to many benefits, radioiodine is preferred in most of the adult patients with Graves' hyperthyroidism while only small proportion of patients is sent to surgery. Radioiodine is especially the treatment of choice in elderly patients and patients with heart disease. In these patients radioiodine is indicated immediately after reaching euthyroidism with antithyroid drugs. Surgery is mainly indicated in younger patients, in the case of patient preference or in special indications. Clear indications for surgical treatment of Graves' hyperthyroidism are: suspected or confirmed malignancy, coexisting pathology that demands surgical treatment, pregnancy and breastfeeding, large goiter (> 80 grams) or goiter with symptoms and signs of compression, severe toxic side effects of antithyroid medications, requirement for immediate control of disease, age younger than 5 years and active ophtalmopathy. The risk of surgical treatment is negatively correlated with the surgeon's experience and nowadays

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

    Graves' orbitopathy has a deteriorating effect on patients' appearance and vision, thus significantly decreases their quality of life. A multidisciplinary team of endocrinologists, ophthalmologists, head and neck surgeons, nuclear medicine physicians, radiologists, and psychologists should constitute a standard health care team for those patients. It is vital that the therapy is based on an individual approach, with patients being well informed and involved in the decision-making process. Generally, traditional therapies include immunosuppression with steroids, orbital irradiation and surgical decompression. Novel treatment modalities include: biological agents, somatostatin analogs, antioxidants, methotrexate. Better insight into pathogenesis of Graves' orbitopathy is the only chance for targeted therapy development. PMID:26966785

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

    Graves disease is an autoimmune disorder characterized by goitre, hyperthyroidism and, in 25% of patients, Graves ophthalmopathy. The hyperthyroidism is caused by thyroid hypertrophy and stimulation of function, resulting from interaction of anti-TSH-receptor antibodies (TRAb) with the TSH receptor on thyroid follicular cells. Measurements of serum levels of TRAb and thyroid ultrasonography represent the most important diagnostic tests for Graves disease. Management of the condition currently relies on antithyroid drugs, which mainly inhibit thyroid hormone synthesis, or ablative treatments ((131)I-radiotherapy or thyroidectomy) that remove or decrease thyroid tissue. None of these treatments targets the disease process, and patients with treated Graves disease consequently experience either a high rate of recurrence, if receiving antithyroid drugs, or lifelong hypothyroidism, after ablative therapy. Geographical differences in the use of these therapies exist, partially owing to the availability of skilled thyroid surgeons and suitable nuclear medicine units. Novel agents that might act on the disease process are currently under evaluation in preclinical or clinical studies, but evidence of their efficacy and safety is lacking. PMID:24126481

    In Germany, patients with Graves' disease are usually treated with radioiodine after unsuccessful antithyroid drug medication, occurrence of side effects from antithyroid drugs or an increased risk from surgery. In patients with normal or only slightly enlarged thyroid glands (volume < or = 50 ml), radioiodine therapy is particularly effective. Radioiodine is the preferential treatment for Graves' patients with high titres of TSH-receptor antibodies and cigarette smoking. Children are still rarely treated with radioiodine in Germany. In contrast, treatment with radioiodine should be more liberally applied in elderly patients with subclinical hyperthyroidism and cardiac symptoms. Individual dosimetry to determine the therapeutic activity is mandatory in Germany. Patients with large goitres obviously need higher organ doses than patients with smaller goitres or normal thyroid glands. Antithyroid drug treatment may interfere with radioiodine therapy. Therefore, it is recommendable to withdraw antithyroid drugs several days before treatment with radioiodine is initiated (and a preceding radioiodine uptake test is performed). In patients with Graves' orbitopathy prophylaxis with corticosteroids can prevent the worsening of symptoms that may be induced by radioiodine treatment. Currently, a risk adapted procedure is recommended according to which prophylactic medication with corticosteroids before applying radioiodine treatment is not necessary in patients with symptoms of orbitopathy and lack of other risk factors (cigarette smoking, in particular). Present results suggest that the risks of radioiodine treatment in Graves' disease patients are very low, while at the same time the cost-effectiveness of this treatment regimen is high.

    We report a case of a 30-year-old woman who suddenly collapsed after having a physical altercation with her husband. Despite immediate resuscitation, she died on arrival at the hospital. The victim's parents requested an autopsy because they believed that their daughter was killed by her husband. Postmortem examination revealed that the victim had a diffusely enlarged thyroid gland and cardiomegaly with left ventricular hypertrophy. There was no evidence of significant trauma on the body. Further postmortem thyroid function tests and review of her medical history indicated that her death was due to Graves' disease. To the best of our knowledge, this is the first case reported of sudden death due to cardiac arrhythmia from Graves' disease induced by physical and emotional stress associated with the criminal activity of another person. The autopsy findings are described. In addition, the literature is reviewed and the significance of postmortem evaluation of thyroid hormones in the cases of sudden death is discussed. PMID:23919315

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

However, the emphasis and expectation is different in the young person, reflecting a range of considerations including age, pubertal status, disease natural history, likely impact of ATD on disease course and the implications of radiation exposure. New therapeutic strategies that could increase the likelihood of long-term remission are being explored. PMID:26252256

    Graves' disease is the most common cause of hyperthyroidism in children. Most children and adolescents are treated with anti-thyroid drugs as the initial modality. Studies have used Methimazole, Carbimazole and Propylthiouracil (PTU) either as titration regimes or as block and replacement regimes. The various studies of anti-thyroid drug (ATD) treatment of Graves' disease in pediatric patients differ in terms of the regimes, remission rate, duration of therapy for adequate remission, follow up and adverse effects of ATD. Various studies show that lower thyroid hormone levels, prolonged duration of treatment, lower levels of TSH receptor antibodies, smaller goiter and increased age of child predicted higher chance of remission after ATD. A variable number of patients experience minor and major adverse effects limiting initial and long term treatment with ATD. The adverse effects of various ATD seem to more in children compared to that of adults. In view of liver injury including hepatocellular failure need of liver transplantation associated with PTU, the use has been restricted in children. The rate of persistent remission with ATD following discontinuation is about 30%. Radioactive iodine therapy is gaining more acceptance in older children with Graves's disease in view of the limitations of ATD. For individual patients, risk-benefit ratio of ATD should be weighed against benefits of radioactive iodine therapy and patient preferences. PMID:25932387

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

    Graves' ophthalmopathy is a debilitating disease impairing the quality of life of affected individuals. The management of moderate-to-severe active Graves' ophthalmopathy is a major therapeutic challenge, and the treatment outcome is often unsatisfactory. We have carried out a retrospective study to assess the efficacy of combined orbital irradiation and systemic corticosteroids. Ten patients were included; all patients had received 20 Grays to the retrobulbar tissues in ten fractions, and oral or intravenous glucocorticoids. The main therapeutic outcome measures were the criteria of Donaldson and co-workers and a self-assessment evaluation. The quality of life outcome was also evaluated by the GO-QOL (Graves' ophthalmopathy quality of life) questionnaire. Seven patients (70%) demonstrated improvement in ocular parameters; the response was excellent in three cases, good in three cases and fair in one case. Three patients showed no response to the treatment. The self-assessment evaluation showed that 75% of patients were satisfied with the results of the treatment. Proptosis was the most responsive sign to radiation and steroids. A duration of the eye disease of more than 18 months was associated with less improvement and a higher failure of the treatment. Concerning the quality of life, the score for visual fonctionning was 882 +/- 18.2 after treatment, while the score for appearance was 63.3 +/- 23.3. In conclusion, a combination of orbital irradiation and systemic steroids is associated with 70% of favorable responses, but the quality of life is not restored in the same proportions and remains impaired after treatment.

    Airborne hyperspectral imaging (HSI) was assessed as a potential tool to locate single grave sites. While airborne HSI has shown to be useful to locate mass graves, it is expected the location of single graves would be an order of magnitude more difficult due to the smaller size and reduced mass of the targets. Two clearings were evaluated (through a blind test) as potential sites for containing at least one set of buried remains. At no time prior to submitting the locations of the potential burial sites from the HSI were the actual locations of the sites released or shared with anyone from the analysis team. The two HSI sensors onboard the aircraft span the range of 408-2524nm. A range of indicators that exploit the narrow spectral and spatial resolutions of the two complimentary HSI sensors onboard the aircraft were calculated. Based on the co-occurrence of anomalous pixels within the expected range of the indicators three potential areas conforming to our underlying assumptions of the expected spectral responses (and spatial area) were determined. After submission of the predicted burial locations it was revealed that two of the targets were located within GPS error (10m) of the true burial locations. Furthermore, due to the history of the TPOF site for burial work, investigation of the third target is being considered in the near future. The results clearly demonstrate promise for hyperspectral imaging to aid in the detection of buried remains, however further work is required before these results can justifiably be used in routine scenarios.

    Chronic idiopathic urticaria (CIU) is well known to be associated with antithyroid peroxidase antibodies and autoimmune thyroiditis. Coexisting Graves disease has only rarely been observed. We describe 2 patients with CIU who developed autoimmune hyperthyroidism with antithyrotropin receptor antibodies. Antithyroid peroxidase antibodies were also present in 1 of the patients, but both responded poorly to high-dose antihistamine therapy. Both patients improved significantly, and their thyroid function recovered with carbimazole. We advise clinicians to be alert to the symptoms of hyperthyroidism when patients with CIU respond poorly to antihistamine therapy, as prompt treatment of hyperthyroidism significantly improves urticaria.

    Graves' ophthalmopathy (GO) is an autoimmune inflammatory disorder associated with thyroid disease which affects ocular and orbital tissues. GO follows a biphasic course in which an initial active phase of progression is followed by a subsequent partial regression and a static inactive phase. Although the majority of GO patients have a mild, self-limiting, and nonprogressive ocular involvement, about 3–7% of GO patients exhibit a severe sight-threatening form of the disease due to corneal exposure or compressive optic neuropathy. An appropriate assessment of both severity and activity of the disease warrants an adequate treatment. The VISA (vision, inflammation, strabismus, and appearance), and the European Group of Graves' Orbitopathy (EUGOGO) classifications are the two widely used grading systems conceived to assess the activity and severity of GO and guide the therapeutic decision making. A critical analysis of classification, assessment, and management systems is reported. A simplified “GO activity assessment checklist” for routine clinical practice is proposed. Current treatments are reviewed and management guidelines according to the severity and activity of the disease are provided. New treatment modalities such as specific monoclonal antibodies, TSH-R antagonists, and other immunomodulatory agents show a promising outcome for GO patients. PMID:26351570

    The clinical and high-resolution computed tomographic (CT) findings in 71 patients (142 orbits) with Graves orbitopathy and 20 healthy patients (40 orbits) were retrospectively reviewed. The orbits with orbitopathy were subgrouped at clinical examination into those with (n = 18) and those without (n = 124) optic neuropathy. Mean extraocular muscle diameters and the calculated muscle diameter index were significantly increased in all orbits with ophthalmopathy, particularly in those with optic neuropathy. Graves orbitopathy affected the superior muscle group (63.4%) more than the medial (61.3%) or inferior (57%) recti. The most common pattern of muscle involvement involved all five measured extraocular muscles. Solitary muscle involvement most frequently involved the superior muscle group (6.3%). Significant enlargements of the retrobulbar optic nerve sheath and superior ophthalmic vein were noted only in orbits with optic neuropathy. Anterior displacement of the lacrimal gland at CT correlated with clinical palpability and occurred more frequently in patients with optic neuropathy. Severe apical crowding was the most sensitive indication of optic neuropathy at CT. PMID:2243967

    A retrospective analysis was done of the records of 454 patients who received their first /sup 131/I treatment for Graves' disease during six periods covering 1951 to 1978. In the earliest group, 3% of patients were hypothyroid 3 mo after /sup 131/I use, and 40% were hypothyroid at 1 yr. In the most recent group, 36% of patients were hypothyroid at 3 mo and 91% were myxedematous at 1 yr. Although no obvious trends were noted, whether in the number of patients pretreated with thionamide drugs, in the mean 24-hr /sup 131/I uptake, or in the calculated dose of /sup 131/I (muCi/estimated gram of thyroid tissue) during the years of the study, the initial mean dose of /sup 131/I administered increased from 8.1 mCi in the earliest group to 13.8 mCi in the latest group. Concurrently, estimates of gland size increased from a mean of 26 g in the first group to 43 g in the last. If, in patients with Graves' disease, the thyroid gland size did not truly increase during the years of the study, the increasing occurrence of early hypothyroidism seen after /sup 131/I use may reflect the conscious or unconscious decision to use larger doses of /sup 131/I calculated on the basis of inflated estimates of thyroid gland weight.

    Graves' disease, an autoimmune process associated with thyroid dysfunction, can also manifest as remodeling of orbital connective tissue. Affected tissues exhibit immune responses that appear to be orchestrated by resident cells and those recruited from the bone marrow through their expression and release of cytokines and surface display of cytokine receptors. Cytokines are small molecules produced by many types of cells, including those of the “professional” immune system. Aberrant cytokine expression appears to play an important role in the pathogenesis of many human diseases, including thyroid autoimmunity. The skewed pattern of cytokine expression in the thyroid, including the T helper cell bias, may condition the response to apoptotic signals and determine the characteristics of an autoimmune reaction. Furthermore, chemoattractant cytokines, including IL16, RANTES, and CXCL10, elaborated by resident cells in the thyroid and orbit may provoke mononuclear cell infiltration. Other cytokines may drive cell activation and tissue remodeling. Thus cytokines and the signaling pathways they activate represent attractive therapeutic targets. Interruption of these might alter the natural course of Graves' disease and its orbital manifestations. PMID:18713026

    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. In this paper, we review the imaging modalities that aid in the diagnosis and management of Graves' orbitopathy, with special emphasis on the diagnosis of optic nerve dysfunction in this condition.

    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.

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

    Methods for mass-grave documentation have changed markedly since the first forensic investigations nearly 70 years ago. Recently, however, there has been little advancement in developing new and better methodology, especially when compared to other forensic disciplines and even within traditional archaeology. This paper proposes a new approach, using 3D modelling for the documentation and eventual analysis of mass-graves. Structure-from-Motion (SfM), which creates digital 3D models from a set of still photographs, was tested on a small, simulated mass grave. The results of this test suggest that the method offers resolution previously unavailable to mass-grave investigators, and facilitates stronger analytical potential than the more traditional methods. Further tests are needed to validate these methods, but these initial findings are promising and their application could enhance our knowledge of mass grave dynamics. PMID:26874051

    Ablative approaches using radioiodine are increasingly proposed for the treatment of Graves' disease (GD) but their ophthalmologic and biological autoimmune responses remain controversial and data concerning clinical and biochemical outcomes are limited. The aim of this study was to evaluate thyroid function, TSH-receptor antibodies (TRAb) and Graves' ophthalmopathy (GO) occurrence after radioiodine thyroid ablation in GD. We reviewed 162 patients treated for GD by iodine-131 ((131)I) with doses ranging from 370 to 740 MBq, adjusted to thyroid uptake and sex, over a 6-year period in a tertiary referral center. Collected data were compared for outcomes, including effectiveness of radioiodine therapy (RIT) as primary endpoint, evolution of TRAb, and occurrence of GO as secondary endpoints. The success rate was 88.3% within the first 6 months after the treatment. The RIT failure was increased in the presence of goiter (adjusted odds ratio = 4.1, 95% confidence interval 1.4-12.0, P = 0.010). The TRAb values regressed with time (r = -0.147; P = 0.042) and patients with a favorable outcome had a lower TRAb value (6.5 ± 16.4 U/L) than those with treatment failure (23.7 ± 24.2 U/L, P < 0.001). At the final status, 48.1% of patients achieved normalization of serum TRAb. GO occurred for the first time in 5 patients (3.7%) who were successfully cured for hyperthyroidism but developed early and prolonged period of hypothyroidism in the context of antithyroid drugs (ATD) intolerance (P = 0.003) and high TRAb level (P = 0.012). On the basis the results of this study we conclude that ablative RIT is effective in eradicating Graves' hyperthyroidism but may be accompanied by GO occurrence, particularly in patients with early hypothyroidism and high pretreatment TRAb and/or ATD intolerance. In these patients, we recommend an early introduction of LT4 to reduce the duration and the degree of the radioiodine-induced hypothyroidism. PMID:22942775

  6. Monitoring controlled graves representing common burial scenarios with ground penetrating radar

    Implementing controlled geophysical research is imperative to understand the variables affecting detection of clandestine graves during real-life forensic searches. This study focused on monitoring two empty control graves (shallow and deep) and six burials containing a small pig carcass (Sus scrofa) representing different burial forensic scenarios: a shallow buried naked carcass, a deep buried naked carcass, a deep buried carcass covered by a layer of rocks, a deep buried carcass covered by a layer of lime, a deep buried carcass wrapped in an impermeable tarpaulin and a deep buried carcass wrapped in a cotton blanket. Multi-frequency, ground penetrating radar (GPR) data were collected monthly over a 12-month monitoring period. The research site was a cleared field within a wooded area in a humid subtropical environment, and the soil consisted of a Spodosol, a common soil type in Florida. This study compared 2D GPR reflection profiles and horizontal time slices obtained with both 250 and 500 MHz dominant frequency antennae to determine the utility of both antennae for grave detection in this environment over time. Overall, a combination of both antennae frequencies provided optimal detection of the targets. Better images were noted for deep graves, compared to shallow graves. The 250 MHz antenna provided better images for detecting deep graves, as less non-target anomalies were produced with lower radar frequencies. The 250 MHz antenna also provided better images detecting the disturbed ground. Conversely, the 500 MHz antenna provided better images when detecting the shallow pig grave. The graves that contained a pig carcass with associated grave items provided the best results, particularly the carcass covered with rocks and the carcass wrapped in a tarpaulin. Finally, during periods of increased soil moisture levels, there was increased detection of graves that was most likely related to conductive decompositional fluid from the carcasses.

    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.

He had a notable chin-down head position, diplopia in primary position, and 3 mm of left proptosis. He had been diagnosed with Graves disease 3 years before presentation. CT scans showed enlargement of the left inferior and medial rectus muscles with associated stranding of the retrobulbar fat and a low-density heterogeneous mass in the left aspect of the neck protruding in the nasopharynx. Biopsies of the orbit and nasopharynx revealed focal areas of amyloid. This represents the first report of bifocal amyloidomas of the orbit and nasopharynx. PMID:21178798

    Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas and is ultimately due to antibodies interacting with the TSH receptor on thyroid follicular cells [TSH-receptor antibody (TRAb)]. Antithyroid drugs (ATDs) belonging to the family of thionamides are the first-line treatment in Europe. ATD treatment is commonly continued for 18-24 months. Its major limitation is the high rate of relapses after drug withdrawal. Factors particularly bound to subsequent relapses are the large thyroid volume, smoking habit, persistence of TRAb in the circulation at the end of treatment, and the post-partum period. Under these conditions, consideration should be given to a definitive therapy for hyperthyroidism (radioiodine treatment, thyroidectomy), particularly if the patient is at risk of cardiovascular complications that might be exacerbated by persistence or recurrence of hyperthyroidism.

    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. PMID:25061884

    The objective of this study was to compare the results of total thyroidectomy (TT) for hyperthyroidism secondary to Graves' disease (GD) with TT for other benign thyroid diseases to determine if TT should be considered more often as first-line therapy for GD. Seven hundred eighty patients underwent TT for benign disease: 203 for GD, 56 for other hyperthyroidisms, and 521 for other benign diseases from March 1, 2003, to December 31, 2009. The perioperative results of these three groups were compared for demographics, blood loss, operative time, complications, and hospitalization. There were no significant differences among the three groups except the patients with GD were more likely to be younger (42 vs 56 vs 57 years; P < 0.001), have more blood loss (154 vs 99 vs 110 mL; P = 0.05), and were more likely to develop permanent hypoparathyroidism (1.0 vs 1.8 vs 0%; P = 0.03) when compared with other causes of hyperthyroidism and other benign thyroid diseases. Permanent recurrent laryngeal nerve injury did not occur in the GD group (0 vs 0 vs 0.4% nerves at risk; P = 0.69) with transient recurrent laryngeal nerve injury occurring in 1.7 versus 2.7 versus 3.1 per cent nerves at risk (P = 0.35). The lack of a euthyroid state preoperatively had no influence on surgical outcomes or complications. Eighty percent of the TTs for GD were done as same-day outpatient procedures. TT offers a safe, low-risk, and rapid cure for GD to justifiably be considered as a reasonable first-line therapy in selected patients with Graves' hyperthyroidism. PMID:24351357

    Management of Graves' orbitopathy (GO) must be based on the correct assessment of activity and severity of the disease. Activity is usually assessed with the Clinical Activity Score, whereas severity is classified according to a European Group On Graves' Orbitopathy (EUGOGO) consensus statement as mild, moderate-to-severe, and sight-threatening. Myopathic and chronic congestive forms are uncommon clinical presentations of GO. Restoration and maintenance of stable euthyroidism are recommended in the presence of GO.In moderate-to-severe disease, steroids have been widely employed and have shown to possess an anti-inflammatory activity, but about 20-30% of patients are not responsive and present recurrence. Some novel immunosuppressors have already been employed in clinical studies and have shown interesting results, although the lack of randomized and controlled trials suggests caution for their use in clinical practice. Potential targets for therapy in GO are the thyroid-stimulating hormone and the insulin-like growth factor 1 receptor on the fibroblasts, inflammatory cytokines, B and T cells, and the PIK3/mTORC1 signaling cascades for adipogenesis. A recent open study has shown that tocilizumab, an anti-sIL-6R antibody, inactivates GO. Consistent reports on the efficacy of rituximab have recently been challenged by randomized controlled trials.As the main goal of treatment is the well-being of the patient, the therapeutic strategy should be addressed to better suit the patient needs, more than improving one or more biological parameters. The increasing availability of new therapies will expand the therapeutic options for GO patients and allow the clinician to really personalize the treatment to better suit the patients' personal needs.

    Neonates born to mothers with Graves' disease are at risk for significant morbidity and mortality and need to be appropriately identified and managed. Because no consensus guidelines regarding the treatment of these newborns exist, we sought to generate a literature-based management algorithm. The suggestions include the following: (1) Base initial risk assessment on maternal thyroid stimulating hormone (TSH) receptor antibodies. If levels are negative, no specific neonatal follow-up is necessary; if unavailable or positive, regard the newborn as "at risk" for the development of hyperthyroidism. (2) Determine levels of TSH-receptor antibodies in cord blood, or as soon as possible thereafter, so that newborns with negative antibodies can be discharged from follow-up. (3) Measurement of cord TSH and fT4 levels is not indicated. (4) Perform fT4 and TSH levels at day 3 to 5 of life, repeat at day 10 to 14 of life and follow clinically until 2 to 3 months of life. (5) Use the same testing schedule in neonates born to mothers with treated or untreated Graves' disease. (6) When warranted, use methimazole (MMI) as the treatment of choice; β-blockers can be added for sympathetic hyperactivity. In refractory cases, potassium iodide may be used in conjunction with MMI. The need for treatment of asymptomatic infants with biochemical hyperthyroidism is uncertain. (7) Assess the MMI-treated newborn on a weekly basis until stable, then every 1 to 2 weeks, with a decrease of MMI (and other medications) as tolerated. MMI treatment duration is most commonly 1 to 2 months. (8) Be cognizant that central or primary hypothyroidism can occur in these newborns. PMID:26980880

    Thymic hyperplasia is frequently observed in Graves' disease. However, detectable massive enlargement of the thymus is rare, and the mechanism of its formation has remained elusive. This case showed dynamic changes in thymic hyperplasia on serial computed tomography images consistent with changes in serum thyrotropin receptor (TSH-R) antibodies and thyroid hormone levels. Furthermore, the patient's thymic tissues underwent immunohistochemical staining for TSH-R, which demonstrated the presence of thymic TSH-R. The correlation between serum TSH-R antibody levels and thymic hyperplasia sizes and the presence of TSH-R in her thymus suggest that TSH-R antibodies could have a pathogenic role in thymic hyperplasia.

    Graves' disease (GD) is a common thyroid disease, and Graves ophthalmopathy(GO) is the most common extra-thyroidal manifestation of GD. Genetic associations of the thyroid stimulating hormone receptor (TSHR) gene with GD and GO have been studied in different population groups for a long time. We aimed to obtain a more precise estimation of the effects of TSHR single nucleotide polymorphisms (SNPs) on GD/GO using a meta-analysis. Publications were searched on Pub Med and EMBASE up to December 30, 2015. Eight studies involving three SNPs (rs179247, rs12101255, and rs2268458), which included 4790 cases and 5350 controls, met the selection criteria. The pooled odds ratios (OR) and the 95% confidence intervals (CI) were estimated. SNPs rs179247 (dominant model [GG + GA vs. AA]: OR = 0.66, 95%CI: 0.61-0.73, P = 0.000, I(2) = 0%) and rs12101255 (dominant model [TT + TC vs. CC]: OR = 1.67, 95%CI: 1.53-1.83, P = 0.000, I(2) = 0%) were significantly associated with GD in all of the genetic models. TSHR rs12101255 and rs2268458 polymorphisms had no association between GO and GD (GD without GO). The results indicate that rs179247 and rs12101255 are likely to be genetic biomarkers for GD. Further studies with different population groups and larger sample sizes are needed to confirm the genetic associations of the TSHR gene with GD/GO. PMID:27456991

    This project refers to the search for clandestine sites where possibly missing people have been buried based on interpreted near surface high resolution geophysical anomalies. Nowadays, there are thousands of missing people around the world that could have been tortured and killed and buried in clandestine graves. This is a huge problem for their families and governments that are responsible to warranty the human rights for everybody. These people need to be found and the related crime cases need to be resolved. This work proposes to construct a series of graves where all the conditions of the grave, human remains and related objects are known. It is expected to detect contrasting physical properties of soil to identify the known human remains and objects. The proposed geophysical methods will include electrical tomography, magnetic and ground penetrating radar, among others. Two geographical sites will be selected to located and build standard graves with contrasting weather, soil, vegetation, geographic and geologic conditions. Forward and inverse modeling will be applied to locate and enhance the geophysical response of the known graves and to validate the methodology. As a result, an integrated geophysical program will be provided to support the search for clandestine graves helping to find missing people that have been illegally buried. Optionally, the methodology will be tested to search for real clandestine graves.

    Twelve pig carcasses were buried in single, shallow and deep (30 and 90 cm, respectively) graves at an experimental site near Ottawa, Ontario, Canada, with three shallow and three deep wrapped in black plastic garbage bags. An additional six carcasses were left at the surface to decompose, three of which were bagged. Six reference pits without remains were also dug. The objective of this three-year study was to examine the biogeochemistry and utility of nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) in grave detection and whether grave depth or cadaver condition (bagged versus bare) affected soil pore air concentrations and emission of the three gases. Graves showed significantly higher (α=0.05) concentrations and surface fluxes of N2O and CO2 than reference pits, but there was no difference in CH4 between graves and reference pits. While CH4 decreased with depth in the soil profiles, N2O and CO2 showed a large increase compared to reference pits. Shallow graves showed significantly higher emissions and pore air concentrations of N2O and CO2 than deep graves, as did bare versus bagged carcasses. PMID:25544693

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

    Graves' disease is an autoimmune disorder in which autoantibodies to the thyroid-stimulating hormone receptor cause hyperthyroidism through unregulated stimulation of the thyroid-stimulating hormone receptor. Effective management of Graves' disease in pregnancy must address the competing fetal and maternal priorities of controlling hyperthyroidism in the mother on the one hand, and on the other, minimizing the impact of maternal disease and antithyroid drugs on the well-being of the fetus. Optimal strategies for achieving this intricate balance are currently a source of continued debate among thyroid experts and studies in recent decades are now providing greater clarity into the risk posed to the unborn baby by the combination of biochemical, immunological and pharmacological hazards arising from Graves' disease and its therapy. This review summarizes the current best practice and highlights important considerations and areas of uncertainty in the management of Graves' disease in pregnant women. PMID:26041458

    Objective: To observe the clinical efficacy and safety of the traditional Chinese medicine (TCM) mixture Yingliu combined with methimazole medication for the treatment of Graves disease (GD). Method: In a randomized, paralleled control study, 92 GD patients were randomized into a Yingliu mixture treatment and a control treatment group, both receiving methimazole. Both treatments lasted for 12 weeks and outcome parameter were thyroid function, thyroid autoantibodies, TCM symptome scores and safety indicators. Results: The clinical efficiency of the Yingliu mixture-methimazole combination was 92.5% vs. 82.5% (P < 0.05) of the solely methimazole medication group. After 12 weeks treatments the Yingliu mixture in combination with methimazole improved free triiodothyronine (FT3), free tetraiodothyronine (FT4), thyroid-stimulating hormone (TSH) receptor antibody (TRAb) and thyroglobulin antibody (TGAb) values significantly more than methimazole alone and TCM symptome scores were significant lower after 12 week treatment in the Yingliu mixture- methimazole group (P < 0.05). The thyroid enlargement (21 vs. 10, P < 0.05), fatigue (39 vs. 30, P < 0.01) and dry mouth symptoms (37 vs. 29, P < 0.05) were superior improved in the Yingliu than in the control medication group, respectively. There was no significant difference regarding safety evaluations between both treatment groups (P = 0.499). Conclusion: Yingliu mixture as combined medication with methimazole can significantly improve the outcome of a solely methimazole application for GD treatments. PMID:26131218

    Graves disease (GD) can lead to complications such as cardiac arrhythmia and heart failure. Although dilated cardiomyopathy (DCMP) has been occasionally reported in adults with GD, it is rare in children. We present the case of a 32-month-old boy with DCMP due to GD. He presented with irritability, vomiting, and diarrhea. He also had a history of weight loss over the past few months. On physical examination, he had tachycardia without fever, a mild diffuse goiter, and hepatomegaly. The chest radiograph showed cardiomegaly with pulmonary edema, while the echocardiography revealed a dilated left ventricle with an ejection fraction (EF) of 28%. The thyroid function test (TFT) showed elevated serum T3 and decreased thyroid stimulating hormone (TSH) levels. The TSH receptor autoantibody titer was elevated. He was diagnosed with DCMP with GD; treatment with methylprednisolone, diuretics, inotropics, and methimazole was initiated. The EF improved after the TFT normalized. At follow-up several months later, although the TFT results again showed evidence of hyperthyroidism, his EF had not deteriorated. His cardiac function continues to remain normal 1.5 months after treatment was started, although he still has elevated T3 and high TSH receptor antibody titer levels due to poor compliance with drug therapy. To summarize, we report a young child with GD-induced DCMP who recovered completely with medical therapy and, even though the hyperthyroidism recurred several months later, there was no relapse of the DCMP.

    A 25-year-old woman presented with jaundice, palpitation, and weight loss of 5 kg during a period of 2 weeks. Laboratory tests showed elevated levels of liver enzymes (AST 1,282 IU/L, ALT 1,119 IU/L) and total bilirubin (6.4 mg/dL); negative for hepatitis virus infection; elevated serum levels of triiodothyronine (T3, 3.60 ng/dL), free thyroxine (fT4, 3.82 ng/dL), and lowered serum level of thyroid stimulating hormone (TSH, <0.025 μIU/mL); and positive for thyroid stimulating antibody and anti-mitochondrial antibody (AMA). The liver biopsy findings were consistent with autoimmune hepatitis (AIH). Accordingly, oral steroid therapy was started with 60 mg of prednisolone under the impression of AIH associated with Graves' disease. After a week of steroid therapy, the clinical manifestation showed significant improvement, with normalization of both liver and thyroid functions. Diagnosis of the liver condition of patients who present with hyperthyroidism and liver dysfunction is important, so that appropriate therapy can be promptly initiated. PMID:25603854

    In order to evaluate Graves' ophthalmopathy new CT parameters have been introduced such as: the diameters of the five extraocular muscles, the value of their addition, the grade of apical crowding, the enlargement of optic nerve sheaths and of the superior ophthalmic vein, and the anterior displacement of the lacrimal gland. On this subject we report our further experience after reviewing 68 cases in which the new ocular parameters were correlated with altered ocular motility and optic neuropathy. The results confirmed our previous study, dealing with several groups of patients, which at the moment seem to be 2, instead of 3 groups: a) patients with increase in both muscular and fatty tissue (54/68 cases); b) patients with main or exclusive increase in fatty tissue (14/68 cases). Relevant clinical signs were present only in the first group of patients, where the medial, inferior and superior muscles were affected in 53/55, 53/55 and 50/55 cases respectively. A muscle increase by nearly 50% was more frequently found in cases with altered ocular motility, an increase by 90% was often associated with optic neuropathy. In case of optic neuropathy apical crowding was often observed, mainly in coronal scans, together with significant enlargement of the optic nerve sheath and of the superior ophthalmic vein. As to proptosis, preseptal area and anterior displacement of the lacrimal gland, they demonstrated lower correlation with the reference symptoms, even though their occurrence was high in symptomatic patients.

    Since hypothyroidism is commonplace after treatment of Graves' disease with radioiodine, the goal should be cure of hyperthyroidism rather than avoidance of hypothyroidism. To find the optimal dose to accomplish cure, we treated 605 patients with stepwise increasing doses of 3, 4, 5, 6, 8, and 10 mCi, analyzing the relationship of dose, age, sex, gland weight, and thyroidal uptake to cure. Estimates of cure at doses above 10 mCi were made from the literature. Cure was directly related to dose between 5 and 10 mCi. There was no significant relationship between cure and age (chi-square, p = 0.74), sex (chi-square, p = 0.12), and 24-hr uptake if over 30% (chi-square for slope, p greater than 0.10). Cure and gland weight had an inverse relationship (chi-square for slope, 0.01 less than p less than 0.02). We concluded that the optimal 131I dose for curing hyperthyroidism is approximated by starting with 10 mCi and increasing it for unusually large glands or for special patient circumstances.

    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.

    A 50-year-old female patient presented with severe myalgia involving her proximal muscles for 3-4 weeks. She also reported mild thyrotoxic symptoms over the same time period. Examination revealed mild thyrotoxicosis, a moderate diffuse goiter and no eye signs. The clinical picture was dominated by muscle pain and tenderness involving mainly her proximal arms and legs, her calves and her fingers, requiring opiate analgesia. Muscle power and tendon reflexes were normal. Laboratory evaluation revealed undetectable serum thyroid stimulating hormone (TSH) with raised FT4, FT3 and positive TSH receptor antibodies. Treatment with carbimazole was started. Additional laboratory investigations were negative (inflammatory markers, creatine kinase and antibodies to antinuclear antibodies, gastric parietal cell, smooth muscle, mitochondrial, dsDNA, centromere, extractable nuclear antigen (ENA) ribonucleoprotein, ENA Sm, ENA Ro, ENA Anti-La, ENA Scl70, ENA Jo-1, anti-CCP and rheumatoid factor). Further assessment in the rheumatology clinic confirmed there was no small joint tenderness or loss of range of movement of her limbs, but widespread and profound muscle tenderness of the common extensors of the forearms, biceps, trapezius, calves and thighs. She was treated symptomatically with analgesic medication and continued on carbimazole. A month later she was euthyroid and her myalgia had resolved. Hyperthyroidism has a profound effect on skeletal muscle and often leads to myopathy. Severe myalgia in association with Graves' disease is rare and resolves with the restoration of euthyroidism.

    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.

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.

    Graves' disease (GD) is an organ-specific autoimmune disease, and thyrotropin (TSH) receptor (TSHR) is a major autoantigen in this condition. Since the extracellular domain of human TSHR (TSHR-ECD) is shed into the circulation, TSHR-ECD is a preferentially immunogenic portion of TSHR. Both genetic factors and environmental factors contribute to development of GD. Inheritance of human leukocyte antigen (HLA) genes, especially HLA-DR3, is associated with GD. TSHR-ECD protein is endocytosed into antigen-presenting cells (APCs), and processed to TSHR-ECD peptides. These peptide epitopes bind to HLA-class II molecules, and subsequently the complex of HLA-class II and TSHR-ECD epitope is presented to CD4+ T cells. The activated CD4+ T cells secrete cytokines/chemokines that stimulate B-cells to produce TSAb, and in turn hyperthyroidism occurs. Numerous studies have been done to identify T- and B-cell epitopes in TSHR-ECD, including (1) in silico, (2) in vitro, (3) in vivo, and (4) clinical experiments. Murine models of GD and HLA-transgenic mice have played a pivotal role in elucidating the immunological mechanisms. To date, linear or conformational epitopes of TSHR-ECD, as well as the molecular structure of the epitope-binding groove in HLA-DR, were reported to be related to the pathogenesis in GD. Dysfunction of central tolerance in the thymus, or in peripheral tolerance, such as regulatory T cells, could allow development of GD. Novel treatments using TSHR antagonists or mutated TSHR peptides have been reported to be effective. We review and update the role of immunogenic TSHR epitopes and HLA in GD, and offer perspectives on TSHR epitope specific treatments. PMID:27602020

    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.

    In 40 patients with Graves' disease (35 female, 5 male; mean age at presentation = 38 yrs) the authors examined the ability of thyroidal /sup 99m/Tc uptake and serum thyroid stimulating immunoglobins (TSI) to identify patients who would relapse after a course of medical therapy. Serum TSI and 20 minute thyroidal /sup 99m/Tc uptake were estimated every 3 months during a 12 month course of carbimazole and tri iodothyronine. TSI levels were estimated by inhibition of receptor binding and expressed as an index (normal value <25). 17 patients (Group 1) remained biochemically euthyroid for at least 1 year after cessation of therapy. 23 (Group II) developed recurrent thyrotoxicosis. Thyroid hormone level did not differ between Groups I and II at presentation. /sup 99m/Tc uptake did not differ significantly in the two groups at presentation and overlap of values persisted throughout therapy. 3 patients had undetectable TSI levels at presentation and throughout follow-up. In the remaining 37, TSI levels at presentation were significantly higher in Group II and all 7 patients with initial values >80 relapsed. After 12 months therapy a TSI level of >25 was present in 1 Group I patient and 16 Group II patients who had detectable TSI at presentation. /sup 99m/Tc uptake was a poor predictor of relapse of thyrotoxicosis. A very high TSI level at presentation (>80) was associated with relapse. An abnormal TSI on completion of 12 months medical therapy had a sensitivity of 86% and a specificity of 94% for prediction of relapse of thyrotoxicosis in the subsequent year.

    Genetic factors, including cytokine gene polymorphisms, are potential contributors to the pathogenesis of the Graves' disease (GD). We attempted in this study to determine the association between GD and the following polymorphisms in the interleukin-1 (IL-1) family genes: IL-1alpha (-889C/T), IL-1ss (-511C/T), IL-1ss (+3962C/T), IL-1R (Pst-1 1970C/T) and IL-1RA (Mspa-I 11100C/T). We studied 107 patients with an established diagnosis of GD and 140 healthy controls. Cytokine typing was performed by the polymerase chain reaction with sequence-specific primers assay. Genotype distributions among patients were in Hardy-Weinberg equilibrium for all polymorphisms. The frequency of the IL-1alpha -889T allele was significantly higher in patients than in controls (51.9% vs. 31.6%, OR=2.33, 95% CI=1.61-3.38; p<0.0001). The IL-1RA Msp-I 11100C allele was significantly more frequent in patients than in controls (50.0% vs. 22.9%, OR=3.38, 95% CI=2.29-4.97, p<0.0001). No significant associations were found for other polymorphisms. Although the IL-1 family has well-known roles in GD pathogenesis, the contributions of their genetic variations to the disease are unclear. In this study, we documented a highly significant association between GD and polymorphism in IL-1alpha and IL-1RA genes. Further studies in other populations are necessary to confirm our results.

    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. PMID:26425375

    Les traumatismes graves du rein de grade III, IV et V selon la classification de l'Amercan Society for Surgery For Trauma (ASST) sont plus rares et se retrouvent dans 5% des cas en moyenne. Leur prise en charge est souvent délicate, nécessitant alors des centres expérimentés dotés de moyen adéquats d'imagerie (scanner spiralé). Cependant, durant ces dernières années, la prise en charge de ces traumatismes a évolué vers une attitude de moins en moins chirurgicale grâce à l’évolution des techniques de la radiologie interventionnelle, de l'endourologie et des moyens de surveillance aux urgences et de réanimation. L'objectif de cette étude est d’évaluer notre expérience dans la prise en charge des traumatismes rénaux de haut grade. Notre étude rétrospective porte sur 25 cas de traumatismes grave du rein de grade III, IV et V selon la classification de l'ASST, colligés entre Janvier 2002 et Juin 2009 au service d'urologie du centre Hospitalier Universitaire Mohammed VI, Université Cadi Ayyad de Marrakech, Maroc. Nous avons étudié les données épidémiologiques, les signes cliniques et biologiques à l'admission (état de choc hémorragique, taux d'hémoglobine), les données radiologiques (échographie et scanner), les lésions associées, la prise en charge thérapeutique et les complications. L’âge moyen de nos patients était de 24,9 ans 15 et 58 ans, avec une prédominance masculine (sex-ratio = 7, 3). Le rein droit était intéressé dans 15 cas (60%). Le traumatisme rénal était fermé dans 15 cas, et ouvert par arme blanche dans 10 cas. Huit patients se sont présentés en état de choc hémorragique (32%). Une anémie inférieur à 10g /100ml a été observée dans 10 cas (40%). L'uroscanner fait systématiquement à l'admission a retrouvé un grade III (10 cas), grade IV (13 cas) et grade V (2 cas).

    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

    Graves’ disease (GD) is a common thyroid disease, and Graves ophthalmopathy(GO) is the most common extra-thyroidal manifestation of GD. Genetic associations of the thyroid stimulating hormone receptor (TSHR) gene with GD and GO have been studied in different population groups for a long time. We aimed to obtain a more precise estimation of the effects of TSHR single nucleotide polymorphisms (SNPs) on GD/GO using a meta-analysis. Publications were searched on Pub Med and EMBASE up to December 30, 2015. Eight studies involving three SNPs (rs179247, rs12101255, and rs2268458), which included 4790 cases and 5350 controls, met the selection criteria. The pooled odds ratios (OR) and the 95% confidence intervals (CI) were estimated. SNPs rs179247 (dominant model [GG + GA vs. AA]: OR = 0.66, 95%CI: 0.61–0.73, P = 0.000, I2 = 0%) and rs12101255 (dominant model [TT + TC vs. CC]: OR = 1.67, 95%CI: 1.53–1.83, P = 0.000, I2 = 0%) were significantly associated with GD in all of the genetic models. TSHR rs12101255 and rs2268458 polymorphisms had no association between GO and GD (GD without GO). The results indicate that rs179247 and rs12101255 are likely to be genetic biomarkers for GD. Further studies with different population groups and larger sample sizes are needed to confirm the genetic associations of the TSHR gene with GD/GO. PMID:27456991

    There is continuing debate on the optimal treatment for Grave's thyrotoxicosis with a resultant variation in clinical practice. The present study aimed to ascertain changes in practice in the treatment of Grave's thyrotoxicosis in Tayside, Scotland, over the past four decades. Methods. The “Scottish automated follow-up register” (SAFUR) was queried to identify all patients treated for Grave's thyrotoxicosis from 1968 to 2007 inclusive. Patients were divided into 4 groups (Groups A to D) according to the decades. Demographic profile, treatment modalities, radioactive iodine (RAI) dose, and recurrence rates were studied and outcomes were compared by χ2 test and ANOVA using SPSS v15.0. A p value of < 0.05 was considered significant. Results. Altogether, 3737 patients were diagnosed with Grave's thyrotoxicosis over the 4 decades. Use of RAI has increased from 43.1% in Group A to 68% in Group D (p < 0.001). The dose of RAI has increased (p < 0.001) and there has been a reduction in recurrence rate with higher dose of RAI. Surgical intervention rates decreased from 55.3% to 12.3% (p < 0.001) over time. Conclusions. Analysis of a large dataset of patients with Grave's thyrotoxicosis suggests increasing use of RAI as the preferred first line of treatment. Furthermore, using a single higher dose of RAI and adoption of total thyroidectomy have decreased recurrence rates. PMID:27313946

    Linford, N.

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

    Moyamoya disease is a cerebrovascular condition that results in the narrowing of the vessels of the circle of Willis and collateral vessel formation at the base of the brain. Although relationships between Graves' disease and cerebrovascular accidents in Moyamoya disease are obscure, the coexistence of the two diseases is noteworthy. Moyamoya disease has been rarely reported in adolescent patients with thyrotoxicosis. Recently, we encountered two adolescent Korean patients with Moyamoya disease associated with Graves' disease who presented with episodic right-sided hemiparesis and syncope. These two girls who had Graves' disease had no history of other diseases or head trauma. A thyroid function test revealed a euthyroid state and a high thyroid-stimulating hormone (TSH) receptor antibody titer at that time. The patients were diagnosed with Moyamoya disease based on brain magnetic resonance angiography and cerebral four-vessel angiography. The patients underwent cranial revascularization by encephalo-duroarterio-synangiosis as soon as a diagnosis was made, which resulted in successful symptom resolution. They fared well and had no additional neurological symptoms as of their last follow-up visits. Here, we report these two cases of confirmed Moyamoya disease complicated by Graves' disease with a review of the literature, and discuss the possible association between the two diseases. To our knowledge, this is the first report in South Korea on Moyamoya disease associated with Graves' disease in adolescents with a euthyroid. PMID:25076974

    The aim of the present study was to monitor long term antithyroid drug treatments and to identify prognostic factors for Graves' disease (GD). A total of 306 patients with GD who were referred to the Endocrinology Clinic at Weifang People's Hospital (Weifang, China) between August 2005 and June 2009 and treated with methimazole were included in the present study. Following treatment, patients were divided into non-remission, including recurrence and constant treatment subgroups, and remission groups. Various prognosis factors were analyzed and compared, including: Patient age, gender, size of thyroid prior to and following treatment, thyroid hormone levels, disease relapse, hypothyroidism and drug side-effects, and states of thyrotropin suppression were observed at 3, 6 and 12 months post-treatment. Sixty-five patients (21.2%) were male, and 241 patients (78.8%) were female. The mean age was 42±11 years, and the follow-up was 31.5±6.8 months. Following long-term treatment, 141 patients (46%) demonstrated remission of hyperthyroidism with a mean duration of 18.7±1.9 months. The average age at diagnosis was 45.6±10.3 years in the remission group, as compared with 36.4±8.8 years in the non-remission group (t=3.152; P=0.002). Free thyroxine (FT)3 levels were demonstrated to be 25.2±8.9 and 18.7±9.4 pmol/l in the non-remission and remission groups, respectively (t=3.326, P=0.001). The FT3/FT4 ratio and thyrotrophin receptor antibody (TRAb) levels were both significantly higher in the non-remission group (t=3.331, 3.389, P=0.001), as compared with the remission group. Logistic regression analysis demonstrated that elevated thyroid size, FT3/FT4 ratio and TRAb at diagnosis were associated with poor outcomes. The ratio of continued thyrotropin suppression in the recurrent subgroup was significantly increased, as compared with the remission group (P=0.001), as thyroid function reached euthyroid state at 3, 6 and 12 months post-treatment.

    Context: Thyrotoxic periodic paralysis (TPP) is a potentially life-threatening complication of hyperthyroidism that is underdiagnosed and frequently missed. It is relatively common in Asian men with Graves' disease. TPP attacks are frequently associated with hypokalemia. Case Report: Here we report a non-Asian female patient with Graves' disease, who presented with flaccid paralysis associated with an episode of subacute thyroiditis (SAT). Interestingly, she was found to have low normal potassium levels in the serum during the initial attack despite which she continues to require low dose potassium supplementation to prevent recurrent TPP attacks. Unique features in our patient include her gender, ethnicity, time lag between initial diagnosis of Graves' disease, and the development of TPP and borderline low potassium levels, with the continuous need for prophylactic potassium supplementation. Conclusion: It is important to be aware of this complication of hyperthyroidism that has a dramatic yet variable presentation, but is readily amenable to therapy. PMID:25839004

    An association between Graves' disease and the human leukocyte antigen (HLA) system has previously been reported. The disease was more strongly associated with the HLA D locus antigen Dw3 than with HLA B8. Products of the HLA D locus are determined by the interaction of test cells with standard typing lymphocytes, a technically difficult procedure. Recently, it has been possible to type serologically for D locus related (DRw) specificities on peripheral bone marrow-derived (B) lymphocytes. Blood B lymphocytes from 50 unrelated controls and 41 patients with Graves' disease were typed for seven HLA DRw specificities. 28 patients with Graves' disease (68%) were positive for DRw3, in contrast to 14 controls (28%); whereas only 21 patients (50%) were HLA B8 positive, compared with 13 (26%) controls. Thus, positivity for DRw3 afforded a relative risk for Graves' disease of 5.5, whereas that for HLA B8 amounted to 3.0. Additionally, a family with multiple cases of Graves' disease in which the disease was previously shown to be inherited with the haplotype, was linked to DRw2, which suggests that the susceptibility to the disease was inherited in association with that antigen. Two HLA B/glyoxalase recombination events were observed in this family; in both instances HLA DRw followed HLA B. This study thus demonstrates that the disease susceptibility gene for Graves' disease is in strong linkage disequilibrium with DRw3; however, it may be associated with other DRw specificities and inherited within family units in association with them.

    Graves' hyperthyroidism and its main extrathyroidal manifestation, Graves' orbitopathy (GO) are characterized by an increased oxidative stress. Treatment of hyperthyroidism with antithyroid drugs is usually associated with an amelioration of biochemical parameters associated with oxidative stress. Association of antithyroid drugs with antioxidants may favor a prompter control of thyroid hyperfunction. Reactive oxygen species may contribute to the pathogenesis of GO. A recent, large, multicenter, randomized, placebo-controlled clinical trial in patients with mild GO clearly demonstrated that selenium supplementation has beneficial effects on the quality of life and the overall ophthalmic involvement of these patients, while reducing the risk of progression to more severe forms of GO.

    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.

    ABSTRACT Basedow-Graves disease is an autoimmune condition with multiple local and systemic aspects. Among these, oculopathy has a major impact on patient's life from both functional and esthetic point of view. Basedow-Graves oculopathy requires an appropriate positive and differential diagnosis using clinical and imagistic approaches. Treatment is always required in moderate or severe forms and it begins with simple general points and continues with medical and surgical therapies. Current article stresses upon the most characteristic clinical signs of thyroidian ophthalmopathy and the required current therapeutic approaches. PMID:22205899

    TSH receptor antibody (TRAb) titer has been reported to be correlated with Graves' ophthalmopathy (GO). However, the correlation between GO activity and TRAb titer assessed with a third-generation assay has not been reported. We enrolled 238 untreated Graves' disease patients who came to the outpatient clinic of Ito Hospital and 28 patients who were euthyroid. All of the patients were assessed for GO by an ophthalmologist within 3 months of their initial visit to Ito Hospital. Clinical activity score (CAS), short inversion time inversion recovery (STIR), and sum of the maximum external orbital muscle areas (SEOMA) on a frontal sectional magnetic resonance imaging (MRI). The TRAb titer was significantly higher in patients with inactive ophthalmopathy (the inactive-GO group) than in patients with active ophthalmopathy (the active-GO group) (17.7 ± 13.5 IU/L vs 13.0 ± 13.1 IU/L, p=0.0082). The SEOMA values were not correlated with TRAb titer. The prevalence of active-GO was higher in euthyroid patients than in hyperthyroid patients although the difference was not significant. In conclusion, TRAb titer measured with a third-generation assay dose not correlate with GO activity based on MRI findings in untreated Graves' disease patients, and the prevalence of active-GO is higher in euthyroid patients with lower TRAb titers than in hyperthyroid patients.

    Objective. Thyroid disease has been reported among the endocrinopathies that can occur after treatment with ipilimumab. Graves' disease, however, has been rarely reported with this medication. Here we report a case of Graves' disease diagnosed after initiation of ipilimumab in a patient with melanoma. Methods. We present the clinical presentation and management course of this patient followed by a related literature review. Results. A 67-year-old male with metastatic melanoma was started on ipilimumab. He developed hyperthyroidism after two doses of ipilimumab. The cause of hyperthyroidism was determined to be Graves' disease. Ipilimumab was held and the patient was started on methimazole with return to euthyroid status. Ipilimumab was resumed and the patient continued methimazole during the course of ipilimumab therapy, with controlled hyperthyroidism. Restaging studies following four cycles of ipilimumab showed complete response in the lungs, with residual melanoma in the neck. The patient then underwent total thyroidectomy and left neck dissection as a definitive treatment for both hyperthyroidism and residual melanoma. Conclusion. Graves' disease can develop after starting ipilimumab and methimazole can be an effective treatment. For patients whose hyperthyroidism is well-controlled on methimazole, ipilimumab may be resumed with close monitoring. PMID:26881150

    Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to deficiency of sex steroid hormone. Graves' disease is also an important cause of secondary osteoporosis. However, IHH does not preclude the development of primary hyperthyroidism caused by Graves' disease, leading to more severe osteoporosis rapidly. Here, we describe the first case of 35-year-old Asian female patient with IHH accompanied by Graves' disease and osteoporosis-induced multiple fractures. Endocrine laboratory findings revealed preserved anterior pituitary functions except for secretion of gonadotropins and showed primary hyperthyroidism with positive autoantibodies. Sella magnetic resonance imaging showed slightly small sized pituitary gland without mass lesion. Dual energy X-ray absorptiometry revealed severe osteoporosis in lumbar spine and femur neck of the patient. Plain film radiography of the pelvis and shoulder revealed a displaced and nondisplaced fracture, respectively. After surgical fixation with screws for the femoral fracture, the patient was treated with antithyroid medication, calcium, and vitamin D until now and has been recovering fairly well. We report a patient of IHH with Graves' disease and multiple fractures that is a first case in Korea. PMID:26981520

    In homicide investigations, it is critically important that postmortem interval and postburial interval (PBI) of buried victims are determined accurately. However, clandestine graves can be difficult to locate; and the detection rates for a variety of search methods (ranging from simple ground probing through to remote imaging and near-surface geophysics) can be very low. In this study, simulated graves of homicide victims were emplaced in three sites with contrasting soil types, bedrock, and depositional environments. The long-term monthly in situ monitoring of grave soil water revealed rapid increases in conductivity up to 2 years after burial, with the longest study evidencing declining values to background levels after 4.25 years. Results were corrected for site temperatures and rainfall to produce generic models of fluid conductivity as a function of time. The research suggests soilwater conductivity can give reliable PBI estimates for clandestine burials and therefore be used as a grave detection method. PMID:26190264

    Incidental papillary carcinoma of the thyroid in patients treated surgically for benign thyroid diseases including Graves' disease is a known phenomenon. However, the management of these patients remains an issue of concern and controversy for those who care for them. We report a case of metastatic papillary carcinoma of the thyroid in a patient previously treated for Graves' disease. The subject of this presentation is a 50-year-old lady who was diagnosed with Graves' disease at the age of 29, for which she had a subtotal thyroidectomy following failure of medical and radioactive iodine treatment. Three years later, the patient was referred to our nuclear medicine department with a clinical diagnosis of suspected metastatic lymph nodes presumably from a thyroid malignancy.She had an 123I diagnostic whole body scan that showed 123I avid areas in the thyroid bed as well as left cervical lymph nodes, which later turned out to be metastatic papillary carcinoma of the thyroid on histology. She was treated with therapeutic doses of 131I. Follow-up radioactive iodine scans and serum thyroglobulin assays showed no evidence of malignant thyroid tissue. The occurrence of papillary carcinoma of the thyroid after a subtotal thyroidectomy for Graves' disease is hereby reported. The need for vigilance and regular follow-up in patients who receive all forms of treatment for benign thyroid diseases is emphasized. PMID:24705115

  2. The role of TSH receptor antibodies in the management of Graves' disease.

    The central role of thyrotropin receptor antibodies (TRAbs) in the pathogenesis of Graves' disease has been recognised for several decades. However, the practical application of testing for TRAbs in clinical decision making remains the subject of controversy. The diagnosis of Graves' disease can be made in most cases simply based on a patient's clinical presentation. The TRAb test is therefore of most value in ambiguous clinical scenarios such as in the differential diagnosis of unilateral exophthalmos, euthyroid Graves' ophthalmopathy, subclinical hyperthyroidism, thyrotoxicosis associated with hyperemesis gravidarum, amiodarone-induced thyrotoxicosis and painless thyroiditis. It may also have a role in predicting the risk of a recurrence of Graves' disease following a course of antithyroid drug treatment. One further clinical utility of the TRAb test is in pregnancy where antibody titre measured during the third trimester is used to predict the risk of neonatal thyroid dysfunction. The TRAb titre not only aids in clinching a difficult diagnosis but can also help guide treatment in some patients. Although the TRAb assay has become more affordable in recent years, cost remains an important factor when considering its use routinely. Nonetheless, this is an underutilised blood test that could augment standard endocrine investigations in the differential diagnosis of hyperthyroidism. PMID:21570635

    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

    The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by aplasia of the uterus and the upper part of the vagina in an XX individual with normal development of secondary sexual characteristics. Individuals with this syndrome may also present with renal and skeletal abnormalities. We report a case of a 16-year-old girl presenting with thyrotoxicosis and primary amenorrhea. After being diagnosed with Graves disease, this patient was placed on antithyroid medication. Although her thyroid function normalized, she did not start to menstruate. Therefore, we assessed her primary amenorrhea and diagnosed the patient with MRKH syndrome through pelvic imaging. To our knowledge, an association between Graves disease and MRKH syndrome has not yet been reported. PMID:23329766

    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.

    1985-06-01

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

    Immunomodulatory effects of low-dose radiotherapy (LD-RT) have been used for the treatment of several benign diseases, including arthrodegenerative and inflammatory pathologies. Graves' disease is an autoimmune disease and radiotherapy (RT) is a therapeutic option for ocular complications. The dose recommended in the clinical practice is 20 Gy (2 Gy/day). We hypothesized that lower doses (<10 Gy total dose, <1 Gy/day) could results in higher efficacy if we achieved anti-inflammatory and immunomodulatory effects of LD-RT. We review current evidence on the effects of RT in the treatment of Graves' disease and the possible use of LD-RT treatment strategy. PMID:27601953

    In California conservatorship is a legal mechanism that allows an individual or agency (the conservator) to act on behalf of a gravely disabled mentally ill person (the conservatee) to determine what arrangements are necessary to provide adequate food, clothing, shelter, and treatment, including hospitalization when indicated. Conservatorship can play an important role in clinical management and treatment, particularly if the gravely disabled person does not have close family involvement and support, as case histories indicate. The benefits of conservatorship can be greatly enhanced by combining it with case management. When family members are appointed as conservators, skilled clinical staff can help them use the leverage of conservatorship therapeutically. By giving up some of their freedom, many conservatees who would ordinarily need to be hospitalized for long periods are able to retain most of their independence and their community status.

    A 35-year-old woman with postoperative recurrent Graves' disease presented with a 5-day history of a red swelling on the right cheek associated with 4 days of remittent hyperpyrexia. Investigations revealed fever, a gangrenous ulcer on the right cheek, submandibular lymphadenopathy, and thyroid gland enlargement. Her white blood cell count, immunoglobulins, and lymphocyte subsets were unremarkable. Thyroid function tests showed low thyroid-stimulating hormone, high free thyroxine, and elevated radioactive iodine uptake. Repeated pus cultures grew Pseudomonas aeruginosa, but blood cultures were negative. An ill-demarcated erythematous plaque occurred on the right leg on hospital day 3. She was treated with intravenous antibiotics with topical gentamicin, recombinant bovine basic fibroblast growth factor, and radioiodine therapy with anti-thyroid drugs. The ulcer healed leaving a depressed scar at 35 days after discharge. This patient may represent the first case of P. aeruginosa ecthyma gangrenosum and cellulitis in postoperative recurrent Graves' disease. PMID:24560831

    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.

    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.

    This preliminary study was undertaken to investigate the efficacy of high-dose iv methylprednisolone pulse therapy in 5 patients with Graves' ophthalmopathy. One gram of methylprednisolone sodium succinate was given iv daily for 3 successive days. The 3-day infusion was repeated 3 to 7 times at intervals of 1 week; total duration of pulse therapy was 3 to 7 weeks. The clinical improvement of eye involvements by pulse therapy was assessed immediately after the last pulse therapy. The clinical assessment of the effect of pulse therapy for Graves' ophthalmopathy showed a good response in 3 patients, a fair response in one, and no response in one. However, in one patient, who was judged to show no response, complete improvement of the enlarged extraocular muscle was observed on orbital computed tomography. Moreover, two patients, who have been followed without any other therapies, showed no relapse of eye involvements for 32 and 10 months, respectively. Although it is impossible to determine whether pulse therapy is more effective than other immunosuppressive therapies, the results of this preliminary study suggest that pulse therapy may be a good immunosuppressive therapy for Graves' ophthalmopathy too. Controlled studies are desired. PMID:3321820

    2000-05-07

    A software system, GRAVE (Geometry Rendering and Visual Editor), has been developed at the Oak Ridge National Laboratory (ORNL) to perform interactive visualization and development of models used as input to the TORT three-dimensional discrete ordinates radiation transport code. Three-dimensional and two-dimensional visualization displays are included. Display capabilities include image rotation, zoom, translation, wire-frame and translucent display, geometry cuts and slices, and display of individual component bodies and material zones. The geometry can be interactively edited and saved in TORT input file format. This system is an advancement over the current, non-interactive, two-dimensional display software. GRAVE is programmed in the Java programming language and can be implemented on a variety of computer platforms. Three- dimensional visualization is enabled through the Visualization Toolkit (VTK), a free-ware C++ software library developed for geometric and data visual display. Future plans include an extension of the system to read inputs using binary zone maps and combinatorial geometry models containing curved surfaces, such as those used for Monte Carlo code inputs. Also GRAVE will be extended to geometry visualization/editing for the DORT two-dimensional transport code and will be integrated into a single GUI-based system for all of the ORNL discrete ordinates transport codes.

    Context: The immune response in autoimmune thyroid disease has been shown to occur primarily within the thyroid gland in which the most abundant antigens can be found. A variety of capture molecules are known to be expressed by thyroid epithelial cells and serve to attract and help retain an intrathyroidal immune infiltrate. Objective: To explore the entire repertoire of expressed genes in human thyroid tissue, we have deep sequenced the transcriptome (referred to as mRNA-Seq). Design and Patients: We applied mRNA-Seq to thyroid tissue from nine patients with Graves' disease subjected to total thyroidectomy and compared the data with 12 samples of normal thyroid tissue obtained from patients having a thyroid nodule removed. The expression for each gene was calculated from the sequencing data by taking the median of the coverage across the length of the gene. The expression levels were quantile normalized and a gene signature was derived from these. Results: On comparison of expression levels in tissues derived from Graves' patients and controls, there was clear evidence for overexpression of the antigen presentation pathway consisting of HLA and associated genes. We also found a robust disease signature and discovered active innate and adaptive immune signaling networks. Conclusions: These data reveal an active immune defense system in Graves' disease, which involves novel molecular mechanisms in its pathogenesis and development. PMID:24971664

    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.

    The aim of this study was to analyze the serum levels of activin A in hyperthyroid patients with Graves' disease. Serum activin A and FSH levels were measured in a total of 93 females (64 regularly cycling and 29 post-menopausal). Of these, 20 were hyperthyroid patients with Graves disease, 33 were euthyroid goitrous patients (20 had autoimmune thyroiditis AT and 13 only had goiter) representing the internal control group and 40 were healthy subjects representing the external control group. Serum levels of activin A were higher in goitrous patients with AT than in control subjects (p=0.0388). Activin A levels were almost doubled in the cycling and in post-menopausal hyperthyroid women (0.91+/-0.21 vs 0.43+/-0.07 microg/l; p<0.0001 and 0.92+/-0.22 vs 0.48+/-0.24 microg/l; p=0.0001, respectively). In 10 cycling hyperthyroid patients, studied even after methimazole treatment, that increase was substantially reversed, once euthyroidism was attained (p=0.002). These findings indicate that thyroid function and autoimmune processes significantly affect serum levels of activin A in patients with Graves' disease. PMID:12553556

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

    Graves' disease is an autoimmune disease. It accounts for 50-80% of cases of hyperthyroidism. Antibodies against the TSH receptor (TRAb) are responsible for hyperthyroidism (TRAB). The key role in monitoring and diagnosis of Graves' disease plays the level of hormones of free thyroxine and triiodothyronine. Helpful is an ultrasound of the thyroid scintigraphy which due to its functional character is both a valuable addition to morphological studies as well as plays an important role in the diagnosis and therapy in patients with Graves' disease. There is no perfect treatment for Graves' disease. The reason for this is the lack of therapy directed against primary pathogenic mechanisms. Currently available treatments need to be thoroughly discussed during the first visit as the patient's understanding of the choice of a treatment constitutes a vital role in the success of therapy. Graves' disease treatment is based on three types of therapies that have been carried out for decades including: pharmacological treatment anti-thyroid drugs, I131 therapy and radical treatment - thyroidectomy. The purpose of the treatment is to control symptoms and patient to return to euthyreosis. Treatment of Graves' disease is of great importance because if left untreated, it can lead to long-term harmful effects on the heart, bone and mental well-being of patients. PMID:26315874

    Background Radioactive iodine as a treatment modality has been shown in several studies to be a safe and effective therapy for Graves disease. However, there is still no uniformity regarding optimal dosing method. The aim of this study is to compare the efficacy of calculated and fixed dosing of radioiodine for the treatment of Graves disease. Methods A hundred twenty-two patients diagnosed with Graves disease were randomized to receive either fixed or calculated dose of radioiodine. Those randomized to fixed activity received either low fixed activity at 9.9 mCi for thyroid gland size <40 g or high fixed activity at 14.9 mCi for thyroid gland size 40 to 80 g, and those grouped to calculated activity received 160 µCi/g of thyroid tissue adjusted for 24 hours radioiodine uptake. Thyroid function tests (free thyroxine [T4] and thyroid stimulating hormone [TSH]) were monitored at 10, 16, and 24 weeks after radioactive iodine therapy. The primary outcome, treatment failure was defined as persistently elevated free T4 and low TSH. Results Of the 122 patients randomized, 56 in the fixed dose group and 56 in the calculated dose group completed the follow-up. At the end of 6 months, the percentage of treatment failure was 37.50% in the calculated dose group versus 19.64% in the fixed dose group with a relative risk of 0.53 (95% confidence interval, 0.28 to 0.98) favoring the fixed dose group. Conclusion Fixed dose radioiodine has a significantly lower incidence of persistent hyperthyroidism at 6 months post-radioactive therapy. PMID:26996425

Dans notre étude parmi 39 patients ayant présenté des réactions immunoallergiques, 10 avaient des formes graves. Le délai moyen d'apparition des signes était de 23 jours. Les réactions immunoallergiques observées étaient 5 cas de toxidermie généralisée fébrile, un cas de Dress syndrome, un cas de neutropénie, un cas de pancitopénie et 2 cas de thrombopénie. Tous nos patients avaient bien évolué cliniquement et bactériologiquement après l'adoption d'un régime thérapeutique excluant le ou les médicaments incriminés. En pratique, si l'effet indésirable imputé à un antituberculeux est grave, il est impératif de l'arrêter, de traiter l'incident et d'associer une autre molécule chez certains cas. Notre étude a montré une fréquence significative des complications graves probablement sous-estimée, surtout dans les pays fortement touchés par l'infection HIV.

    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.

    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.

  8. 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.

    The TSH receptor (TSHR) A-subunit is more effective than the holoreceptor in inducing thyroid-stimulating antibodies (TSAb) that cause Graves' disease. A puzzling phenomenon is that 2 recombinant, eukaryotic forms of A-subunits (residues 22-289), termed active and inactive, are recognized mutually exclusively by pathogenic TSAb and mouse monoclonal antibody 3BD10, respectively. Understanding the structural difference between these TSHR A-subunit forms could provide insight into Graves' disease pathogenesis. The 3-dimensional structure of the active A-subunit (in complex with a human TSAb Fab, M22) is known, but the structural difference with inactive A-subunits is unknown. We solved the 3BD10 Fab 3-dimensional crystal structure. Guided by prior knowledge of a portion of its epitope, 3BD10 docked in silico with the known active TSHR-289 monomeric structure. Because both TSAb and 3BD10 recognize the active TSHR A-subunit monomer, this form of the molecule can be excluded as the basis for the active-inactive dichotomy, suggesting, instead a role for A-subunit quaternary structure. Indeed, in silico analysis revealed that M22, but not 3BD10, bound to a TSHR-289 trimer. In contrast, 3BD10, but not M22, bound to a TSHR-289 dimer. The validity of these models is supported experimentally by the temperature-dependent balance between active and inactive TSHR-289. In summary, we provide evidence for a structural basis to explain the conformational heterogeneity of TSHR A-subunits (TSHR-289). The pathophysiologic importance of these findings is that affinity maturation of pathogenic TSAb in Graves' disease is likely to involve a trimer of the shed TSHR A-subunit. PMID:25419797

    Three patients with Graves disease had very unusual locations of localized myxedema. One patient had localized myxedema on the pretibial and shoulder areas after sodium iodide I 131 therapy. The second patient had localized myxedema on his neck, shoulders, and upper part of the back as well as on the pretibial area. The third patient had localized myxedema on the pinnae, also following sodium iodide I 131 therapy. After surgical removal followed by intralesional triamcinolone acetonide injections, the first patient's lesions recurred. The lesions in the second case did not respond to topical steroid cream. The third patient had a partial response to intralesional steroid injections.

    With the exception of exhumations of mass graves in Latin America, forensic dentists and odontologists are rarely involved in the examination of mortal remains recovered from mass graves. The cited reason is often that "there are no dental records-so what is the point"? In this presentation we review the published accounts of examination of remains arising from the conflict in the former Yugoslavia between 1991 and 1999 in which dental examinations are reported. There are roughly 30,000 missing persons of which more than 15,000 mortal remains have been identified, mostly based on DNA. There are 9 sources which describe postmortem dental examinations of 3919 sets of remains; of these, 23% were purported to have been identified specifically from dental information. Of the 8100 listed missing persons from the Srebrenica mass killings in 1995, we located 600 dental records. A sample of 263 charts was examined for information about first molar treatment as we are concerned that dental charting of individuals who lose their first molars may be incorrectly done if allowance is not made for mesial drift of the remaining molars. We found that of all the first molar extractions that are ever going to occur according to these dental charts, 63% have taken place by age 18. The majority of extracted first molars have a functional age of 17 years. We observe that an adult's remains from Srebrenica usually have only second and third molars, which have often drifted forward to occupy the position of the first molar creating the appearance of third molar agenesis. We conclude: that, since dental identifications of victims in mass graves and mass disasters is the exception rather than the rule, even in the absence of DNA-based identifications, international forensic odontologists have an ethical obligation to become more involved in examination of mass grave victims, that there must be more determined searches for antemortem dental records; that local dentists should be approached

    Ophthalmic Graves' disease and histiocytosis X involving the orbit are occasionally refractory to treatment, so that vision may be threatened. In these situations megavoltage external beam radiotherapy should be employed, and the indications for this treatment are discussed. A highly accurate technique is described, using precise planning with information obtained from high definition CT scans, a complete patient head shell for immobilisation, and modern megavoltage radiotherapy treatment machines. As a result the dose to the lens is minimised (to a maximum of 10% of the prescribed dose), and late morbidity will be small. Two cases are described to illustrate this procedure and the response to treatment. Images PMID:3259894

We herein report effects of thyroid hormone on the pathological condition of NASH in a patient with NASH complicated by Graves' disease. In our case, the liver enzyme level improved with the increasing thyroid hormone level; however, the liver enzyme level was aggravated with the improving thyroid hormone level.

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

    We have tested the possible association of HLA-DQB and HLA-DPB alleles with Graves' thyrotoxicosis, with or without severe ophthalmopathy, by polymerase chain amplification of genomic DNA and allele-specific oligonucleotide probing. There was no significantly abnormal distribution of DQB alleles compared to 50 control subjects except for a reduced prevalence of DQw 3.1 in the Graves' patients with severe ophthalmopathy (X2 = 6.23, P less than 0.02). HLA-DPB 2.1/8 was found in only 1 of 40 of these patients compared with 15 of the controls (X2 = 11.49, P less than 0.001). Ten of 48 patients with Graves' disease but without clinically significant eye involvement were HLA-DPB 2.1/8 positive, not significantly different from controls, but significantly different from the ophthalmopathy group (X2 = 6.70, P less than 0.01). The other DPB alleles in both groups of Graves' disease patients were the same as controls. These results suggest that HLA-DPB 2.1/8 may confer a protective effect in Graves' disease with respect to ophthalmopathy. PMID:2401099

    Thyroid ophthalmopathy is a rare extra-thyroid complication usually associated with Graves' disease. This disease can occur in the euthyroid pregnant patient. Graves' orbitopathy is characterized by eyelid retraction, proptosis, extraocular muscle dysfunction, and periorbital edema. In some cases an emergency surgical repair may be required to avoid irreversible vision loss. We present the case of a 35-year-old woman in her 30th gestational week, who suffered from Graves' ophthalmopathy, severe exophthalmia, and visual acuity decrease. Following consultations among anesthesiologists, ophthalmologists, maxillofacial surgeons, endocrinologists, obstetricians and the patient, it was decided to perform a surgical orbital wall decompression. The anesthetic and perioperative implications associated with gestational age and the considerations for this surgical procedure, and how to avoid increasing intraocular pressure are discussed.

    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. PMID:24812529

    A simulated clandestine shallow grave was created within a heterogeneous, made-ground, urban environment where a clothed, plastic resin, human skeleton, animal products, and physiological saline were placed in anatomically correct positions and re-covered to ground level. A series of repeat (time-lapse), near-surface geophysical surveys were undertaken: (1) prior to burial (to act as control), (2) 1 month, and (3) 3 months post-burial. A range of different geophysical techniques was employed including: bulk ground resistivity and conductivity, fluxgate gradiometry and high-frequency ground penetrating radar (GPR), soil magnetic susceptibility, electrical resistivity tomography (ERT), and self potential (SP). Bulk ground resistivity and SP proved optimal for initial grave location whilst ERT profiles and GPR horizontal "time-slices" showed the best spatial resolutions. Research suggests that in complex urban made-ground environments, initial resistivity surveys be collected before GPR and ERT follow-up surveys are collected over the identified geophysical anomalies.

    New-onset Graves' ophthalmopathy (GO) following radioiodine treatment (RAI) and worsening of existing GO are well-described in the endocrinology literature. These phenomena are recognized by ophthalmologists, yet poorly documented in the ophthalmology literature. Two male patients, aged 43 and 62 years, respectively, with Graves' disease without GO, received RAI. Four months later, one patient developed acute GO with unilateral reduction in visual acuity, conjunctival chemosis, lagophthalmos, bilateral severely restricted ocular motility, and lid retraction. High-dose intravenous steroids, followed by oral steroids, led to a dramatic clinical improvement. The second patient received a second dose of RAI for persistent hyperthyroidism and subsequently developed acute GO-comprising restricted ocular motility, peri-orbital swelling, and conjunctival chemosis. Symptoms gradually resolved on continued carbimazole treatment. Neither patient received pre-RAI prophylactic glucocorticoids, as currently they are only recommended for patients with pre-existing GO or multiple risk factors. We discuss the limitations of using this risk-based approach in preventing new-onset GO following RAI therapy. PMID:24409943

    Graves' disease (GD) is frequently associated with mild hypercalcemia. The hypercalcemia may be due to the activation of osteoclastic bone resorption caused by the excess thyroid hormone. In some cases of GD, the hypercalcemia can be attributable to concomitant parathyroid diseases. In this study, 21 patients with a history of GD developed parathyroid adenoma based on histology, intraoperative parathyroid hormone (IOPTH) monitoring, and other clinical features. There were 11 patients with a history of radioactive iodine therapy (RAI) for GD. The latency time of RAI was from 12 to 41 years. The case cohort was divided into two groups: patients with (group GR: 11 patients) and patients without a history of RAI (group G: 10 patients). Mean age of patients in group GR was 54.8 years compared to 62.2 years of group G (P = 0.08). There were no statistically significant differences regarding the parathyroid weight, serum calcium, and pre- and post-parathyroidectomy PTH levels. There was no histopathologic difference between the two groups. In conclusion, we report 21 cases of parathyroid adenoma in patients with Graves' disease. There may be a possible link between GD patients with a RAI history and an increased risk of parathyroid adenoma. The parathyroid adenomas showed no clinicopathological differences between GD patient with and without a history of RAI. PMID:25501495

    Since the identification of somatostatin receptors on lymphocytes, orbital infiltration with mononuclear cells in Graves' ophthalmopathy has provided a rationale for receptor imaging with the radiolabeled somatostatin analog Octreotide. In 40 patients with Graves' ophthalmopathy and 10 controls, 110 MBq indium-Octreotide were administered i.v., and scans were performed at 4 and 24 h after injection. An uptake ratio between the orbits and the brain was determined. In 20 ophthalmophathy patients, magnetic resonance imaging (MRI) of the orbits was performed and the T2 relaxation time was measured within the rectus muscles. Compared to controls (4 h Octreotide uptake: median 6.0 counts/pixel/MBq, orbit/brain ratio 5.6), ophthalmopathy patients showed a 2- to 3-fold increased uptake (15.8 counts/pixel/MBq vs controls p = 0.0032; ratio 12.6, vs controls p = 0.003). When considering patients with active disease only, a higher uptake was registered (16.8 counts/pixel/MBq vs controls p 0.0048, ratio 15.6 vs controls p = 0.0006). Untreated patients showed a markedly higher uptake (23 counts/pixel/MBq) compared to patients receiving steroid therapy (12.6, p = 0.001). MRI of the orbit revealed a correlation between T2 relaxation time of the eye muscles and orbital uptake of Octreotide (p < 0.001). PMID:7647569

    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.

  6. A case of Graves' disease with false hyperthyrotropinemia who developed silent thyroiditis.

    We encountered a patient who developed silent thyroiditis during the course of Graves' disease. The diagnosis of silent thyroiditis was made on the basis of a low thyroidal 131I uptake, no response to the thyrotropin releasing hormone (TRH) test, and subsequent hypothyroidism despite the presence of high titers of thyrotropin (TSH) receptor antibody (TRAb) and thyroid stimulating antibody (TSAb). The patient, in addition, had a discrepancy between serum TSH and thyroid hormone values. This was due to the presence of interfering substances that react to mouse IgG in the sera since serum TSH levels were decreased in a dose dependent manner by the addition of increasing amounts of mouse IgG to the sera. It should therefore be noted that silent thyroiditis can develop in patients with Graves' disease. Furthermore, clinicians should be aware that two-site immunoassay kits that use mouse monoclonal antibodies are subject to interference by some substances, possibly antibodies which react to mouse IgG.

    A retrospective analysis was done of the records of 454 patients who received their first I-131 treatment for Graves' disease during six periods covering 1951 to 1978. In the earliest group, 3% of patients were hypothyroid 3 mo after I-131 use, and 40% were hypothyroid at 1 yr. In the most recent group, 36% of patients were hypothyroid at 3 mo and 91% were myxedematous at 1 yr. Although no obvious trends were noted, whether in the number of patients pretreated with thionamide drugs, in the mean 24-hr I-131 uptake, or in the calculated dose of I-131 (..mu..Ci/estimated gram of thyroid tissue) during the years of the study, the initial mean dose of I-131 administered increased from 8.1 mCi in the earliest group to 13.8 mCi in the latest group. Concurrently, estimates of gland size increased from a mean of 26 g in the first group to 43 g in the last. If, in patients with Graves' disease, the thyroid gland size did not truly increase during the years of the study, the increasing occurrence of early hypothyroidism seen after I-131 use may reflect the conscious or unconscious decision to use larger doses of I-131 calculated on the basis of inflated estimates of thyroid gland weight.

    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. PMID:26864507

    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 .

    Combined segregation and linkage analysis is a powerful technique for modeling linkage to diseases whose etiology is more complex than the effect of a well-described single genetic locus and for investigating the influence of single genes on various aspects of the disease phenotype. Graves disease is familial and is associated with human leukocyte antigen (HLA) allele DR3. Probands with Graves disease, as well as close relatives, have raised levels of thyroid autoantibodies. This phenotypic information additional to affection status may be considered by the computer program COMDS for combined segregation and linkage analysis, when normals are classified into diathesis classes of increasing thyroid autoantibody titer. The ordinal model considers the cumulative odds of lying in successive classes, and a single additional parameter is introduced for each gene modeled. Distributional assumptions are avoided by providing estimates of the population frequencies of each class. Evidence for linkage was increased by considering the thyroid autoantibody diathesis and by testing two-locus models. The analysis revealed evidence for linkage to HLA-DR when the strong coupling of the linked locus to allele DR3 was considered (lod score of 6.6). Linkage analysis of the residual variation revealed no evidence of linkage to Gm, but a suggestion of linkage to Km. 32 refs., 10 tabs.

    The present study reports the case of a female Chinese patient with Graves' disease (GD) and severe Graves' ophthalmopathy (GO) in its active phase, who was treated with propylthiouracil and oral prednisolone for 2 months at a local hospital. However, a lack of improvement in symptoms meant that the patient was transferred to the First Affiliated Hospital of Xi'an Jiaotong University (Xi'an, China), whereupon the patient received high-dose intravenous methylprednisolone pulse therapy, although with limited efficacy. Subsequently, rituximab (RTX; anti-CD20 monoclonal antibody) combined with orbital irradiation treatment was initiated. The patient responded positively to the combined treatment; the clinical symptoms and enlargement of the extraocular muscles were ameliorated, and there were marked decreases in the clinical activity and NOSPECS grading scores. Furthermore, the serum levels of anti-thyrotropin receptor antibodies (TRAb) were markedly decreased at 2 months following RTX therapy. The patient was maintained in a euthyroid state by treatment with methimazole during and following RTX therapy. It was concluded that RTX treatment may attenuate severe GO by depleting lymphocytes, and may promote the recovery of GD by reducing the serum levels of TRAb. PMID:27446325

  12. Use of antihistamines after serious allergic reaction to methimazole in pediatric Graves' disease.

    2014-05-01

    Antithyroid drugs are usually considered first-line therapy for management of pediatric Graves' disease because they avoid permanent hypothyroidism, provide a chance for remission, and are less invasive than the alternatives of thyroidectomy or radioactive iodine. Methimazole (MMI) is the only antithyroid drug recommended in pediatrics due to the risk of propylthiouracil-induced liver toxicity. Allergic reactions with MMI occur in up to 10% of patients and, when mild, can be managed with concurrent antihistamine therapy. Guidelines recommend discontinuation of MMI with serious allergic reactions. We present the case of an adolescent girl with Graves' disease and a serious allergic reaction after starting MMI whose family refused radioactive iodine and was reluctant to proceed to surgery. Antihistamine therapy was successfully used to allow continued treatment with MMI. This case demonstrates extension of management guidelines for minor cutaneous allergic reactions to MMI, through the use of antihistamines for a serious allergic reaction, allowing us to continue MMI and provide treatment consistent with the family's preferences and values.

    La cellulite cervico-faciale grave est une infection polymicrobienne extensive et redoutable du tissu cellulo-adipeux de la face et du cou. 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

    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. PMID:22148004

    The Iberomaurusian necropolis of Taforalt (Morocco, 11-12000 BP), excavated by Roche in the 1950s, contains 28 multiple graves. The funerary practices of the Taforalt population have been the focus of a previous work (Mariotti et al., 2009). In the absence of the excavation records of the necropolis, these funerary practices were investigated through the analysis of the contents of each grave and the distribution of intentionally modified specimens (ochre-dyeing, cut marks). Previous research has drawn particular attention to Grave XII (containing three male adults and two juveniles), where many intentionally modified specimens were identified. The present study focused specifically on the human remains recovered from Grave XII. Analysis of these remains has provided evidence of interventions, such as dismemberment and defleshing of the cadaver, and the use of ochre to colour the bones. Furthermore, the presence of lesions on two skulls suggests the possibility of intentional killing and cannibalism among the Taforalt population. This study further supports our previous impression of the complex and diversified funerary practices, characterising the social life of the Iberomaurusian population of Taforalt. PMID:20471665

    Osteoporosis-related fractures are one of the complications of Graves' disease. This study hypothesized that the different actions of thyroid-stimulating hormone receptor (TSHR) antibodies, both stimulating and blocking activities in Graves' disease patients might oppositely impact bone turnover. Newly diagnosed premenopausal Graves' disease patients were enrolled (n = 93) and divided into two groups: patients with TSHR antibodies with thyroid-stimulating activity (stimulating activity group, n = 83) and patients with TSHR antibodies with thyroid-stimulating activity combined with blocking activity (blocking activity group, n = 10). From the stimulating activity group, patients who had matched values for free T4 and TSH binding inhibitor immunoglobulin (TBII) to the blocking activity group were further classified as stimulating activity-matched control (n = 11). Bone turnover markers BS-ALP, Osteocalcin, and C-telopeptide were significantly lower in the blocking activity group than in the stimulating activity or stimulating activity-matched control groups. The TBII level showed positive correlations with BS-ALP and osteocalcin levels in the stimulating activity group, while it had a negative correlation with the osteocalcin level in the blocking activity group. In conclusion, the activation of TSHR antibody-activated TSH signaling contributes to high bone turnover, independent of the actions of thyroid hormone, and thyroid-stimulation blocking antibody has protective effects against bone metabolism in Graves' disease.

    Graves' disease (GD) may be observed as an infrequent adverse effect after radioiodine therapy (RAIT) for toxic thyroid adenoma (TA) and toxic multi nodular goiter (MNG). We present a case of a 55-year-old male with a toxic nodule who was treated with RAI. After therapy, the patient's serum free triiodothyronine (fT3) and free thyroxine (fT4) levels gradually increased. Antithyroid peroxidase (TPOAb), antithyroglobulin (TgAb) and TSH-receptor antibodies (TRAb) were also positive. Thyroid scintigraphy revealed diffuse intense uptake after four months of RAIT. Radiation-induced GD should be considered in patients with aggravated hyperthyroidism 3-4 months after therapy. PMID:27529890

    For almost three decades, interest has continued to increase with respect to the application of fiber-optic sensing techniques for the upstream oil and gas industry. This paper reviews optical sensing technologies that have been and are being adopted downhole, as well as their drivers. A brief description of the life of a well, from the cradle to the grave, and the roles fiber-optic sensing can play in optimizing production, safety, and protection of the environment are also presented. The performance expectations (accuracy, resolution, stability, and operational lifetime) that oil companies and oil service companies have for fiber-optic sensing systems is described. Additionally, the environmental conditions (high hydrostatic pressures, high temperatures, shock, vibration, crush, and chemical exposure) that these systems must tolerate to provide reliable and economically attractive oilfield monitoring solutions are described.

    A 26-year-old Hispanic man with no significant medical history presented to our emergency room with gradual onset weakness of his lower extremities. He was haemodynamically stable and examination revealed loss of motor function in his lower limbs up to the level of hips. Laboratory data revealed hypokalaemia. The patient was started on potassium supplementation and he recovered his muscle strength. Differential diagnosis included familial hypokalaemic periodic paralysis and thyrotoxic periodic paralysis (TPP). Further investigations revealed a low thyroid-stimulating hormone and high free thyroxine levels. Radio iodine 123 scan revealed an enhanced homogeneous uptake in the thyroid suggesting Graves' disease. Thyroid stimulating antibodies were also found to be elevated. The patient was started on methimazole and propranolol and he never had another attack of TPP even at 1 year follow-up. PMID:24717588

    Adrenal crisis is a potential life threatening complication. The common causes of adrenal crisis are infections, surgical stress and abrupt cessation of steroid medications. Endocrine causes like Graves' disease with thyrotoxicosis is one of the less common causes of an adrenal crisis. We report a 42-year-old female who presented with recurrent episodes of adrenal crisis due to delayed diagnosis of thyrotoxicosis. She was initially treated with Carbimazole followed by Radio-iodine ablation and currently she is euthyroid. Her adrenal insufficiency was initially treated with hydrocortisone during the time of adrenal crisis followed by Prednisolone 5 mg once daily in the morning along with fludrocortisone 50 mcg once daily. This case highlights the need for high index of suspicion and less common causes like thyrotoxicosis should be ruled out in patients with adrenal crisis. PMID:27190873

    To date, 49 feldspathic lunar meteorites (FLMs) have been recovered, likely representing a minimum of 35 different sample locations in the lunar highlands. The compositional variability among FLMs far exceeds the variability observed among highland samples in the Apollo and Luna sample suites. Here we will discuss in detail one of the compositional end members of the FLM suite, Graves Nunataks (GRA) 06157, which was collected by the 2006-2007 ANSMET field team. At 0.79 g, GRA 06157 is the smallest lunar meteorite so far recovered. Despite its small size, its highly feldspathic and highly magnesian composition are intriguing. Although preliminary bulk compositions have been reported, thus far no petrographic descriptions are in the literature. Here we expand upon the bulk compositional data, including major-element compositions, and provide a detailed petrographic description of GRA 06157.

    Technetium 99 conjugated with methylene diphosphonate, which is an anti-inflammatory drug, can inhibit macrophage infiltration and downregulate a number of proinflammatory cytokines, such as tumor necrosis factor-α and interleukin-1β. Recently, numerous studies have indicated that it could improve rheumatoid arthritis (RA) activity by upregulating the frequency of peripheral γδ T cells and cluster of differentiation CD4+CD25+Foxp3+ Tregs, affecting the serum cytokine environment, inhibiting osteoclast formation and reducing the concentrations of rheumatoid factor-immunoglobulin M (IgM)/IgG/IgA. As well, it may have a therapeutic role for choroidal neovascularisation (CNV) and Graves' ophthalmopathy (GO). Therefore, it will be a valuable choice in the treatment of RA, CNV and GO.

    Hashimoto's thyroiditis (HT) and Graves' disease (GD) are the 2 most common autoimmune disease processes affecting the thyroid gland. The relationship between the two is complex and not clearly understood. It has been theorized that HT and GD are 2 separate disease processes due to unique genetic differences demonstrated by genome studies. On the other hand, based on occurrence of both HT and GD in monozygotic twins and within the same family, they have been regarded to represent 2 ends of the same spectrum. This case report describes 3 patients who presented with thyrotoxicosis due to both GD and HT. The initial presentation was thyrotoxicosis due to GD treated with antithyroid medication followed by temporary resolution. They all subsequently experienced recurrence of thyrotoxicosis in the form of Hashitoxicosis due to HT, and then eventually all developed thyrotoxicosis due to GD, requiring radioablation therapy.

    Forty-five patients with Graves' disease were studied prospectively to determine if 24-hour I-131 uptake measurements alone or in combination with serum thyroid hormone levels at six weeks would determine the necessity for retreatment of the thyrotoxicosis. All patients with an I-131 uptake greater than 30% at six weeks required retreatment. No patient with an I-131 uptake of less than 15% required retreatment. Patients with uptakes between 15% and 30% were variable. An elevated free thyroxin index at 6 weeks is not helpful to determine which patients will remain thyrotoxic. Patients with a free thyroxin index within the normal range at six weeks can be predicted to be euthyroid by 12 weeks if their 24-hour I-131 uptake is between 15% and 30% and to be hypothyroid if their 24-hour I-131 uptake is below 15%. There was no difference between patient groups treated initially with antithyroid medication and those who were not.

    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.

    The Madaras cemetery is the only one totally excavated Sarmatian site on the Great Hungarian Plain. The cemetery contained 623 graves from the Sarmatian period (from the second century till the middle of the fifth century AD). The preservation of the skeletons are very poor and fragmentary. The ratio of males is 30%, the ratio of skeletons belongig to females is 41%, while the children took 29%. Among pathological cases severe coxarthritis and in one case a metastatic carcinoma of a skull were found. At four individuals artificial deformation of the skull was diagnosed. On the basis of the metric and taxonomic analysis the Madaras population was heterogeneous, wich can be explained by the fact, that this population was diverse or mixed. PMID:20063665

    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. PMID:22569952

  13. Graves' Disease Mechanisms: The Role of Stimulating, Blocking, and Cleavage Region TSH Receptor Antibodies.

    The immunologic processes involved in Graves' disease (GD) have one unique characteristic--the autoantibodies to the TSH receptor (TSHR)--which have both linear and conformational epitopes. Three types of TSHR antibodies (stimulating, blocking, and cleavage) with different functional capabilities have been described in GD patients, which induce different signaling effects varying from thyroid cell proliferation to thyroid cell death. The establishment of animal models of GD by TSHR antibody transfer or by immunization with TSHR antigen has confirmed its pathogenic role and, therefore, GD is the result of a breakdown in TSHR tolerance. Here we review some of the characteristics of TSHR antibodies with a special emphasis on new developments in our understanding of what were previously called "neutral" antibodies and which we now characterize as autoantibodies to the "cleavage" region of the TSHR ectodomain.

    Substantial reductions in thyroid volume (up to 70-80%) after radioiodine therapy of Graves' hyperthyroidism are common and have been reported in the literature. A relationship between thyroid volume reduction and outcome of 131I therapy of Graves' disease has been reported by some authors. This important result could be used to decide individually the optimal radioiodine activity A0 (MBq) to administer to the patient, but a predictive model relating the change in gland volume to A0 is required. Recently, a mathematical model of thyroid mass reduction during the clearance phase (30-35 days) after 131I administration to patients with Graves' disease has been published and used as the basis for prescribing the therapeutic thyroid absorbed dose. It is well known that the thyroid volume reduction goes on until 1 year after therapy. In this paper, a mathematical model to predict the final mass of Graves' diseased thyroids submitted to 131I therapy is presented. This model represents a tentative explanation of what occurs macroscopically after the end of the clearance phase of radioiodine in the gland (the so-called second-order effects). It is shown that the final thyroid mass depends on its basal mass, on the radiation dose absorbed by the gland and on a constant value α typical of thyroid tissue. α has been evaluated based on a set of measurements made in 15 reference patients affected by Graves' disease and submitted to 131I therapy. A predictive equation for the calculation of the final mass of thyroid is presented. It is based on macroscopic parameters measurable after a diagnostic 131I capsule administration (0.37-1.85 MBq), before giving the therapy. The final mass calculated using this equation is compared to the final mass of thyroid measured 1 year after therapy administration in 22 Graves' diseased patients. The final masses calculated and measured 1 year after therapy are in fairly good agreement (R = 0.81). The possibility, for the physician, to decide a

    We report a patient and critically review the literature in order to define the demographic, clinical, neuroradiologic, and treatment features of moyamoya syndrome (MMS) in the setting of Graves' disease (GD). We performed a comprehensive English language Medline search using the keywords "moyamoya," "Graves' disease," and "thyrotoxicosis." We included all patients with angiographic findings consistent with MMS. A 23-year-old woman with active GD presented with intermittent confusion and right arm paresis. Brain magnetic resonance imaging revealed acute left and chronic bilateral hemispheric infarcts. Cerebral angiography revealed multivessel intracranial occlusive disease. Initial treatment with plasmapheresis plus aspirin stabilized the patient's neurologic deficits. Antithyroid treatment plus subsequent surgical encephalomyosynangiosis resulted in prolonged neurologic stability. We studied 30 patients (27 women [90%], 23 of Asian descent [77%]), with a mean age of 29 ± 11.6 years. Hemiparesis (n = 12; 40%) was the leading clinical sign, and ischemic infarction was the most frequent neuroimaging finding (n = 26; 87%). Treatment regimens included antithyroid medications alone (n = 5; 17%), antithyroid plus antiplatelet agents (n = 9; 30%), neurosurgical revascularization after antithyroid medication (n = 11; 37%), and plasmapheresis in the acute thyrotoxic state (n = 2; 7%). Most patients had good short-to-medium term outcome (n = 14; 78% of reported outcome). Plasmapheresis-treated patients achieved neurologic stabilization and had good outcomes. MMS, an infrequent complication of GD, typically affects young women. Our findings indicate that plasmapheresis can stabilize the neurologic picture in the acute phase, and that antithyroid and antiplatelet therapy, combined with revascularization surgery, may improve long-term outcomes. Further work is needed to establish an optimal treatment strategy. PMID:21130668

    Effectiveness of radioiodine for Graves' hyperthyroidism depends also on its intrathyroidal persistence. The latter is enhanced by lithium by blocking iodine release from the thyroid. One hundred ten patients with Graves' hyperthyroidism were randomly assigned to treatment with radioiodine or radioiodine plus lithium, stratified according to goiter size (< or =40 or >40 mL) and evaluated for changes in thyroid function and goiter size, at monthly intervals, for 12 months. Cure of hyperthyroidism occurred in 33 of 46 patients (72%) treated with radioiodine and in 45 of 54 patients (83%) treated with radioiodine plus lithium. The probability of curing hyperthyroidism was higher and its control prompter (P = 0.02) in the radioiodine-plus-lithium group. Patients with < or =40-mL goiters had similar persistence of hyperthyroidism (13%), but lithium-treated patients had hyperthyroidism controlled earlier (P = 0.04). Among patients with >40-mL goiters, hyperthyroidism was cured in 6 of 15 patients (40%) treated with radioiodine alone and in 12 of 16 patients (75%) treated with radioiodine plus lithium (P = 0.07), and cure occurred earlier in the latter (P = 0.05). Goiters shrank in both groups (P < 0.0001), more effectively and promptly (P < 0.0005) in the radioiodine-plus-lithium group. Serum free T4 and T3 levels increased shortly after therapy only in the radioiodine group (P < 0.01). Lithium carbonate enhances the effectiveness of radioiodine therapy, in terms of prompter control of hyperthyroidism, in patients with small or large goiters. In the latter group, lithium also increases the rate of permanent control of hyperthyroidism. PMID:10022407

    Correlating the CT scan features of patients with orbital Graves' disease with histopathologic observations allows one to focus more specifically on the distinguishing features of this disease with future research implications. Both CT scanning and pathologic studies have shown clearly that the extraocular muscles are the primary focus of the disease. Swelling of the extraocular muscles generally occurs within their bellys with sparing of the tendons. This contrast with idiopathic inflammation of the muscles or myositis, which tends to involve the tendon as well. All of the associated findings in orbital Graves' disease probably flow from the enlarged volume of the extraocular muscles: proptosis, bowing of the medial lamina papyracea to accommodate the swollen belly of the medial rectus muscle, venous engorgement from stasis induced by direct compression of the orbital venous drainage, conjunctival and lid swelling, and lacrimal gland enlargement. Both radiographic and pathologic changes in the orbital fat are secondary and comparatively insignificant. While there appears to be no selective inflammation of the optic nerve meninges or the perineural connective tissues, enlargement of the extraocular muscle bellys where they converge at the crowded orbital apex brings about compression of the optic nerve, impairs its function, and causes visual decrease. Lymphocytic and plasmacytic infiltration along with edema within the endomysium of the extraocular muscles leads to the activation of fibroblasts with the production of acid mucopolysaccharides and progressive fibrosis. It is not known what attracts the lymphocytes to the extraocular muscles, why certain extraocular muscles are affected preferentially, why the disease may be asymmetrically unilateral, and whether a defect in T cell or B cell functions (or both) is immunologically at fault.

    The pathogenesis of Graves' ophthalmopathy (GO) remains to be entirely elucidated. The present study aimed to determine the association between phenotypic expression of the MTHFR gene and susceptibility to GO in patients with Graves' disease (GD). A prospective case‑controlled study was conducted with 122 patients with GD and GO (n=72) or without GO (n=50) and 100 healthy controls in South Korea. Patient history, including smoking, nutritional status, thyroid function and antithyroid antibodies were investigated and clinical activity score, VISA classification (which includes vision, inflammation, strabismus and appearance/exposure) and orbit computed tomography were evaluated. Fasting plasma total homocysteine (tHcy) concentration was measured, and genotype analysis of the MTHFR gene was conducted. The TT homozygous genotype was associated with a two‑fold increased risk of GO [adjusted odds ratio (AOR), 2.19; 95% confidence interval (CI), 0.78‑6.14]. However, this result was not significant. The TT genotype significantly increased the risk of GO compared with that in healthy controls (AOR, 2.92; 95% CI, 1.11‑7.65). The MTHFR 677CT/1298AA genotype decreased the risk of GO in patients with GD (AOR, 0.26; 95% CI, 0.08‑0.91). tHcy levels in patients with GD without GO were significantly higher than in patients with GO, however, they were within the normal limit. The current study identified an association between MTHFR polymorphisms and GO. These results will aid understanding of the pathogenesis of GO and facilitate development of genetic therapeutic strategies. PMID:27430300

    Background Hyperthyroidism 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. Methods This 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. Results Twenty-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%. Conclusion TSAb 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. PMID:27118279

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

    Background: The Internet is a vital source of information for patients hoping to learn more about their disease. Health literacy of the general population is known to be poor, with the U.S. Department of Health and Human Services (USDHHS) recommending that patient-oriented literature be written at a fourth- to sixth-grade reading level to optimize comprehensibility. In this study we assessed the readability of online literature specifically for Graves' disease (GD) and thyroid-associated ophthalmopathy (TAO). Methods: Readability of the content of the top 20 English-language GD patient-oriented online resources and top 30 of the equivalent TAO resources returned by Google search was analyzed. Web pages were identified using the Google search terms “Graves' disease” and “Thyroid-Associated Ophthalmopathy,” respectively. Extraneous text (e.g., hyperlinks, affiliations, disclaimers) was removed. Relevant text proceeded to readability analysis using four validated measures: Flesch Reading Ease Score, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, and Gunning-Fog Index. Readability was compared with USDHHS standards. Results: Overall, median word count (with interquartile range [IQR] and range) was 990 (IQR 846, 195–3867), with a median of 18 words per sentence (IQR 4.0, 7.5–28). Median Flesch Reading Ease Score was 46 (IQR 13, 24–64), Flesch-Kincaid Grade Level 11 (IQR 3.0, 7.2–17), Simple Measure of Gobbledygook 13 (IQR 2.0, 9.6–17), and Gunning-Fog Index 13 (IQR 3.0, 9.2–19), each equivalent to a reading level of >11th grade and “difficult” on the USDHHS classification. None of the web pages evaluated had readability scores in accordance with published guidelines. There was no significant difference with the country of origin of each web page, website commercial status, or with pages predominantly focused on GD or TAO. Conclusions: Readability scores for online GD and TAO patient-focused materials are inferior to those recommended

    In July 2007, a group of nineteen K-12 teachers investigated an abandoned cemetery in Prairie View, Texas, utilizing ground-penetrating radar (GPR) to image the subsurface. In a period of two weeks, the group acquired and interpreted 59 GPR profiles in Wyatt Chapel Cemetery and surrounding areas in order to determine the local stratigraphy and try to locate unmarked graves. The sandy soil in this area is ideally suited for GPR investigations and numerous geophysical anomalies were identified. Wyatt Chapel Cemetery is located adjacent to the campus of Prairie View A&M University in Prairie View, TX, and is thought to have originated as a slave burial ground in the 1850's. Participants in a summer course at Rice University conducted a geophysical investigation of the site. Participants were in-service K-12 teachers from urban Houston school districts where the majority of students are members of historically underrepresented minority groups. Recruitment efforts targeted educators who are currently teaching science without a science degree. Participants included elementary, middle and high school teachers. This summer experience is followed by a content-intensive academic year course in Physical Geology. GPR is an excellent tool for investigating the sandy soil encountered at Wyatt Chapel Cemetery. The stratigraphy in the area consists of 3-6 feet of reddish-brown, medium-grained sand overlying a light gray, highly compacted clay. The sand-clay boundary appears as a strong reflector on the GPR profiles. Participants identified numerous anomalies in the GPR data and two were excavated. One consisted of a pair of bright hyperbolae, suggesting two edges of a metal object. This excavation resulted in the discovery of a metal plank thought to be a burial cover. The second anomaly consisted of a break in the horizon representing the top of the clay layer, and subsequent excavation revealed a grave shaft. Participants experienced the process of science first-hand and used

    Purpose: Thyroid {sup 131}I effective half-life (T{sub eff}) is an essential parameter in patient therapy when accurate radiation dose is desirable for producing an intended therapeutic outcome. Multiple {sup 131}I uptake measurements and resources from patients themselves and from nuclear medicine facilities are requisites for determining T{sub eff}, these being limiting factors when implementing the treatment planning of Graves' disease (GD) in radionuclide therapy. With the aim of optimizing this process, this study presents a practical, propitious, and accurate method of determining T{sub eff} for dosimetric purposes. Methods: A total of 50 patients with GD were included in this prospective study. Thyroidal {sup 131}I uptake was measured at 2-h, 6-h, 24-h, 48-h, 96-h, and 220-h postradioiodine administration. T{sub eff} was calculated by considering sets of two measured points (24-48-h, 24-96-h, and 24-220-h), sets of three (24-48-96-h, 24-48-220-h, and 24-96-220-h), and sets of four (24-48-96-220-h). Results: When considering all the measured points, the representative T{sub eff} for all the patients was 6.95 ({+-}0.81) days, whereas when using such sets of points as (24-220-h), (24-96-220-h), and (24-48-220-h), this was 6.85 ({+-}0.81), 6.90 ({+-}0.81), and 6.95 ({+-}0.81) days, respectively. According to the mean deviations 2.2 ({+-}2.4)%, 2.1 ({+-}2.0)%, and 0.04 ({+-}0.09)% found in T{sub eff}, calculated based on all the measured points in time, and with methods using the (24-220-h), (24-48-220-h), and (24-96-220-h) sets, respectively, no meaningful statistical difference was noted among the three methods (p > 0.500, t test). Conclusions: T{sub eff} obtained from only two thyroid {sup 131}I uptakes measured at 24-h and 220-h, besides proving to be sufficient, accurate enough, and easily applicable, attributes additional major cost-benefits for patients, and facilitates the application of the method for dosimetric purposes in the treatment planning of

    During autoimmune disease the fraction of CD4+CD28- T cells in the peripheral blood of has been found to be elevated. In the present study, peripheral blood was collected from 61 patients with Graves' disease (GD) and 30 healthy control participants. Serum concentrations of thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4) and thyrotropin receptor autoantibody (TRAb) were measured and peripheral blood mononuclear cell (PBMC) surface expression of CD4 and CD28 molecules was detected by flow cytometry. CD4+CD28- cells were sorted from six patients undergoing subtotal thyroidectomy and cultured ex vivo. The influence of TSH pretreated thyroid follicular cells on CD4+CD28- cell proliferation was evaluated using the agonist CD40 mAb 5C11, the blocking CD40L mAb 4F1 or B7-1 mAb 4E5 in 3H-TdR assays. Our data showed that the fraction of CD4+CD28- T cells was higher in GD patients than healthy donors (10.21%±8.56% vs. 2.33%±1.94%; P<0.001), and further elevated in 24 of 61 patients with Graves' ophthalmopathy (GO) (7.00±6.57% vs. 15.21±8.96%; P<0.001). A higher proportion of CD4+CD28- cells was detected in patients with degree II or III goiter than those with degree I goiter (11.53±9.18% vs. 6.11±3.97%; P<0.05 and 14.50±10.41% vs. 6.11±3.97%; P<0.01). The percentage of CD4+CD28- T cells correlated positively with serum levels of FT3 (r=0.354, P<0.01) and TRAb (r=0.304, P<0.05), but did not correlate with serum FT4 or TSH. Ex vivo, 5C11 enhanced proliferation of CD4+CD28+ cells (P<0.05), but did not influence the proliferation of CD4+CD28- cells. 4F1 inhibited the proliferation of both CD4+CD28+ (P<0.05) and CD4+CD28- (P<0.01) cells, and 4E5 inhibited proliferation of CD4+CD28+ cells (P<0.05). The elevation in circulating CD4+CD28- cells in GD patients correlates with disease severity and maybe plays an important role in the pathogenesis of GD. PMID:25839128

    Cigarette smoking is the most important risk factor for the development or deterioration of Graves' ophthalmopathy. Smoke-induced increased generation of reactive oxygen species may be involved. However, it remains to be clarified how orbital fibroblasts are affected by cigarette smoking. Our study demonstrated that Graves' orbital fibroblasts have exaggerated response to cigarette smoke extract challenge along with increased oxidative stress, fibrosis-related genes expression, especially connective tissue growth factor, and intracellular levels of transforming growth factor-β1 and interleukin-1β. The findings obtained in this study provide some clues for the impact of cigarette smoking on Graves' ophthalmopathy and offer a theoretical basis for the potential and rational use of antioxidants in treating Graves' ophthalmopathy.

    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

    Recent age constraints on Australia's oldest human remains (Mungo I and III), found at Lake Mungo in western New South Wales, relied on optical dating of sands from the same stratigraphic units as those into which the remains had been inserted (42±3 ka) and those that overlay the graves (38±2 ka), giving a burial age of 40±2 ka. This indirect means of dating the burials was necessary because the original site from which the remains had been excavated had been completely eroded away. At the time of the original excavation of the Mungo III grave, blocks of sediment from the grave-infill were collected for sediment fabric analysis. These sediment blocks were impregnated with polyester resin, sectioned for analysis and the remaining resin-impregnated sediment blocks were then stored in a cupboard, where they have lain for the last 30 years. Here we report on optical dating of single grains of quartz extracted from one of these sediment blocks. Grains extracted from the centre of the block show a wide distribution of equivalent doses (0.0±0.3 to 43.7±8.3 Gy), indicating that not all of the grains have remained hidden from light (light-safe) following excavation. We show that the population of grains with the maximum equivalent dose produces an age consistent with that of the previous study, indicating that some of the grains have remained light-safe. We also use linearly modulated optically stimulated luminescence to identify light-safe grains. These yield an age of 41±4 ka, which represents a direct optical age for the grave-infill and which is consistent with the age obtained in the previous study for sands from the same stratigraphic unit as that containing the burial. The results reported here demonstrate the potential of applying optical dating to archived sediment samples that have not been stored in a light-safe environment.

  9. Semblance analysis to assess GPR data from a five-year forensic study of simulated clandestine graves

    Ground penetrating radar (GPR) surveys have proven useful for locating clandestine graves in a number of forensic searches. There has been extensive research into the geophysical monitoring of simulated clandestine graves in different burial scenarios and ground conditions. Whilst these studies have been used to suggest optimum dominant radar frequencies, the data themselves have not been quantitatively analysed to-date. This study uses a common-offset configuration of semblance analysis, both to characterise velocity trends from GPR diffraction hyperbolae and, since the magnitude of a semblance response is proportional to signal-to-noise ratio, to quantify the strength of a forensic GPR response. 2D GPR profiles were acquired over a simulated clandestine burial, with a wrapped-pig cadaver monitored at three-month intervals between 2008 and 2013 with GPR antennas of three different centre-frequencies (110, 225 and 450 MHz). The GPR response to the cadaver was a strong diffraction hyperbola. Results show, in contrast to resistivity surveys, that semblance analysis have little sensitivity to changes attributable to decomposition, and only a subtle influence from seasonality: velocity increases (0.01-0.02 m/ns) were observed in summer, associated with a decrease (5-10%) in peak semblance magnitude, SM, and potentially in the reflectivity of the cadaver. The lowest-frequency antennas consistently gave the highest signal-to-noise ratio although the grave was nonetheless detectable by all frequencies trialled. These observations suggest that forensic GPR surveys could be undertaken with little seasonal hindrance. Whilst GPR analysis cannot currently provide a quantitative diagnostic proxy for time-since-burial, the consistency of responses suggests that graves will remain detectable beyond the five years shown here.

  10. The Accuracy of the Osteological Sexing of Cremated Human Remains: A Test Based on Grave Goods from East Lithuanian Barrows.

    The accuracy of the sex determination of cremated human remains is one of the vital parameters for archaeologists and skeletal anthropologists dealing with cremations. Few studies have so far aimed at testing it. In the present paper, the accuracy of the sexing techniques was assessed by paralleling biological sex (identified morphologically) to gender (presumed on the basis of the grave goods which accompanied the deceased). A collection of cremated bones from East Lithuanian barrows (c. fourth/fifth--eleventh/twelfth centuries AD) was employed. The fragmentary nature and poor state of the bones generally represents cremains from similar archaeological contexts. The database inevitably underwent several stages of filtration. Out of 364 cremations with a minimum of 445 individuals, only 157 were sexed single adult burials, of which only 81 had "gender-related" grave goods. The relationship of artefact type to gender was defined statistically, revising the results in line with the chronological and typological differences and the probable symbolism of the grave goods. Sex and gender coincided in 56 cases (69.14%), but a considerable distance between the results for both sexes was observed. Biological females displayed a fairly high match level, i.e. 35 out of the 41 (85.37%) individuals osteologically identified as females had been given "feminine" items. The burials of biological males, on the other hand, yielded a surprisingly low match rate, i.e. only 21 out of 40 (52.50%). This disparity suggests a possible misinterpretation of grave goods as gender markers, rather than (only?) erroneous sexing. It is thus argued that for females, the mean value for the accuracy of sexing is 85.5%. In most cases, such precision is entirely satisfactory for the analysis of a poorly-preserved osteological material. For males, however, the accuracy is likely to fall somewhere in the range between 52.5 and 85.5%, with the applied methodology so far failing to contribute to higher

    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. PMID:26921813

    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. PMID:26787873

    Sixty-nine cases of middle aged and senile female Graves' desease (GD) patients suffered from abnormal bone metabolism have been studied. They were divided randomly into group A and B, treated separately with antithyroid drugs (Tapazol and inderal, etc.) in group A, and added with Chinese herbal medicine for tonifying Kidney and promoting blood circulation in group B. Before treatment, patients of both groups showed obvious higher blood calcium (Ca) 24-hour urinary Ca, phosphorus (P) and serum clcitonin (CT) levels than that in normal subjects. These patients' serum Ca, moreover, had a parallel relationship with serum T3 levels (r = 0.6142, P < 0.01) and the serum Ca also a paralleled with serum CT levels (r = 0.5714, P < 0.05). After six months of treatment, the serum Ca, 24-hour urinary Ca, P and blood CT values were all reduced in various degree. The decrease of these bone metabolic parameters were more significant in group B than that in group A. PMID:9387746

    Objective. Thyrotoxic periodic paralysis (TPP) is a potentially life-threatening complication of Graves' disease (GD). The present study compared the long-term efficacy of antithyroid drugs (ATD), radioactive iodine (RAI), and surgery in GD/TPP. Methods. Sixteen patients with GD/TPP were followed over a 14-year period. ATD was generally prescribed upfront for 12–18 months before RAI or surgery was considered. Outcomes such as thyrotoxic or TPP relapses were compared between the three modalities. Results. Eight (50.0%) patients had ATD alone, 4 (25.0%) had RAI, and 4 (25.0%) had surgery as primary treatment. Despite being able to withdraw ATD in all 8 patients for 37.5 (22–247) months, all subsequently developed thyrotoxic relapses and 4 (50.0%) had ≥1 TPP relapses. Of the four patients who had RAI, two (50%) developed thyrotoxic relapse after 12 and 29 months, respectively, and two (50.0%) became hypothyroid. The median required RAI dose to render hypothyroidism was 550 (350–700) MBq. Of the 4 patients who underwent surgery, none developed relapses but all became hypothyroid. Conclusion. To minimize future relapses, more definitive primary treatment such as RAI or surgery is preferred over ATD alone. If RAI is chosen over surgery, a higher dose (>550 MBq) is recommended.

    PurposeTo evaluate the choroidal thickness in patients with Graves orbitopathy (GO) using enhanced depth imaging-optical coherence tomography (EDI-OCT).MethodsThirty-one patients with GO were evaluated prospectively. All subjects underwent ophthalmologic examination including best-corrected visual acuity, intraocular pressure measurement, biomicroscopic, and fundus examination. Choroidal thickness was measured at the central fovea. In addition, visual evoked potential measurement and visual field evaluation were performed.ResultsThe mean choroidal thickness was 377.8±7.4 μ in the GO group, and 334±13.7 μ in the control group. (P=0.004). There was a strong correlation between the choridal thickness and the clinical activity scores (CAS) of the patients (r=0.281, P=0.027). Additionally, there was a correlation between the choroidal thickness and the visual-evoked potential (VEP) P100 latency measurements of the patients (r=0.439, P=0.001).ConclusionsThe results of this study demonstrate that choroid is thicker in patients with GO. The choroidal thickness is also correlated with the CAS and VEP P100 latency measurements in these patients. PMID:27315349

    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.

    We describe autoantibodies against iodinated gastrin in a patient with Graves' disease. Values for serum gastrin differed in this case, depending on which of two different radioimmunoassay (RIA) kits was used. RIA with the dextran-coated charcoal method for separation of free tracer gastrin gave a value less than 9.5 pmol/L, whereas the value by a RIA kit by the double-antibody method was 318 pmol/L. The patient's serum contained a binding protein for /sup 125/I-labeled gastrin, as detected by Sephadex G-200 column chromatography. The IgG fraction was responsible for the ability of serum to bind /sup 125/I-labeled gastrin. Interestingly, of the two possible forms of iodinated gastrins, monoiodinated (MIT) and diiodinated (DIT) tyrosine-/sup 125/I-labeled gastrin, only the latter bound to patient's IgG. Furthermore, DIT-gastrin, but not gastrin or MIT-gastrin, inhibited the binding of DIT-/sup 125/I-labeled gastrin. The patient's serum evidently contains autoantibodies against DIT-gastrin that interfere with RIA of gastrin.

    The authors have established EBV-transformed human B cell clones producing monoclonal antithyrotropin receptor antibodies from two patients with Graves' disease. They then isolated and characterized Ig H chain genes of 5 B cell clones with thyrotropin-binding inhibitor Ig (TBII) activity and 4 B cell clones with thyroid-stimulating antibody (TSAb) activity. They found that V[sub H] gene families used in the 5 TBII clones were diverse, including V[sub H-II, -III, -IV,] and [sub -V]. Most of V[sub H] segments used in TBII and TSAb are commonly used in other autoantibodies and fetal liver repertoire. The frequency of somatic mutations in TBII was higher than that in TSAb. In as much as the same germline V[sub H] segment (V3-23) was used for both TBII and TSAb, the frequency and position of somatic mutations may be important for generation of TBII and TSAb. 56 refs., 2 figs., 2 tabs.

    In 2008, the skeletal remains of more than 60 human individuals were found in a mass grave on the grounds of the University of Kassel, Germany. There was no evidence helping to identify them or throwing light on the cause of their death. Mainly due to 14C age determination and initial hints on age and sex distribution, historians hypothesized that they had been soldiers of Napoleon's army who died in an epidemic in the winter of 1813/14. To test this assumption, morphological and molecular analyses were carried out on a sample. The morphological analyses comprised an age and sex determination as well as a macro- and micro-morphological inspection for pathological deviations after the commingled bones had been assembled as individuals. The molecular investigations aimed to identify the geographic origin of the remains. For this, mitochondrial and Y-chromosomal haplotypings were carried out. The results point to a group of mainly young men, some of them suffering from systemic inflammation of the periosteum. Others revealed severe aberrations in bone microstructure. The greatest similarities revealed by Y-haplogroup and -haplotype distribution were to populations that live in what are now the Benelux countries. All aspects support the thesis that these were soldiers of the Napoleonic army. PMID:22338792

    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. PMID:24347956

    Summary La pharmacologie des agents anesthésiques chez le brûlé est variable et imprévisible. Dans les premières 48 h, il y a une hypovolémie avec chute du débit cardiaque et des fuites plasmatiques. Après 48 h, il y a une hypervolémie avec augmentation du débit cardiaque, hypermétabolisme et la clearance des médicaments est augmentée. Parmi les facteurs de déséquilibre, on retrouve les variations des protéines plasmatiques. Deux protéines sont importantes chez le brûlé grave : l'albumine et l'alpha 1- glycoprotéine. Leur taux varie beaucoup au cours de l'évolution de la brûlure. Les agents anesthésiques dont la liaison avec ces deux protéines est prédominante verront leur pharmacocinétique modifiée. L'anesthésiste-réanimateur du service des brûlés va maîtriser ces notions pharmacologiques pour utiliser à bon escient les agents anesthésiques. PMID:21991108

    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.

    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. PMID:25596556

    We hypothesized that early uptake of iodine-131 (131I) at 3-6 hr (EU) by the thyroid could be used to calculate 131I therapy with results comparable to those obtained using late uptake of 131I at 20-28 hr (LU) results. A retrospective study was undertaken. Twenty-seven patients with untreated thyrotoxic Graves' disease were given 3-5 microCi of 131I and EU and LU were determined with an uptake probe. We derived a best fit curve on plots of EU (X-axis) and LU (Y-axis). The equation for the curve (LU = -55.7 + 73.2 log EU) was used to predict late uptake (PU) from EU results on a second group of 24 similarly defined Graves' patients. PU and measured LU were then applied to 131I treatment calculations in these 24 patients. PU correlated closely with LU (r = 0.94). Dose calculations based on PU and LU gave very similar results (r = 0.97). Using this method, same day diagnosis and treatment of Graves' is achievable.

    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 an

    Aim: To investigate the effects of diosgenin (Dio), a naturally occurring steroid saponin, on goiter formation in a mouse model of Graves' disease (GD) and the underlying mechanisms. Methods: Female BALB/c mice were injected with adenovirus expressing the A subunit of thyrotropin receptor to induce GD. The mice were treated with Dio (20, 100 mg·kg−1·d−1, ip) for 12 or 24 d. The serum levels of TT4 and TRAb were examined using radioimmunoassay and electrochemiluminescence. The size and morphology of thyroid glands were examined. Thyrocyte proliferation was determined using BrdU incorporation assay. The expression of proliferation-associated proteins IGF-1, NF-κB, cyclin D1, and PCNA in thyroids was analyzed using immunohistochemistry and real-time PCR. Results: The GD mice showed significantly high serum levels of TRAb and TT4 compared to the normal mice. Treatment of the GD mice with Dio for 24 d dose-dependently reduced the TT4 level and thyroid size, but did not affect the abnormal level of TRAb. Furthermore, Dio treatment dose-dependently reversed the morphological changes and reduced excessive thyrocyte proliferation in thyroids of the GD mice. Dio treatment also dose-dependently reduced the mRNA and protein levels of IGF-1, NF-κB, cyclin D1, and PCNA in thyroids of the GD mice. Conclusion: Dio relieves goiter in a mouse model of GD through the inhibition of thyrocyte proliferation. The mechanisms involve the suppression of IGF-1, NF-κB, cyclin D1, and PCNA expression.

    Both therapies for Graves' disease (GD), radioactive iodine (RAI) and antithyroid drugs (ATD), were reported to have specific immune effects. We aimed at investigating the effects of RAI therapy on cellular subsets involved in immune regulation. We conducted a thirty day follow-up prospective cohort study of adult patients. Patients eligible for RAI therapy at our centre were approached. Twenty seven patients with GD were recruited, among whom 11 were treated with ATD. Twenty-two healthy subjects (HS) were also studied. Over time, frequency of regulatory T cells (Treg) and of invariant natural killer T cells (iNKT), along with Treg cell-mediated suppression and underlying mechanisms, were monitored in the peripheral blood. Variance in frequency of Treg and iNKT after RAI therapy was higher in GD patients than in HS over time (p < 0.0001). Reduced Treg suppressive function was observed after RAI therapy in GD patients (p = 0.002). ATD medication prior to RAI dampened these outcomes: less variation of Treg frequency (p = 0.0394), a trend toward less impaired Treg function, and prevention of reduced levels of suppressive cytokines (p < 0.05). Shortly after RAI therapy, alterations in immunoregulatory cells in patients with GD were observed and partially prevented by an ATD pretreatment. Worsening of autoimmunity after RAI was explained in previous studies by enhanced immune activity. This study adds new highlights on immune regulation deficiencies after therapeutic interventions in thyroid autoimmunity. PMID:26701678

    Purpose. We wanted to investigate the relative significance of fat and muscle enlargement in the development of dysthyroid optic neuropathy (DON) in Graves' orbitopathy (GO). Methods. Preoperative coronal CT scans of 13 patients with and without DON who subsequently underwent orbital decompression were retrospectively analyzed. Thirteen patients imaged for unilateral orbital fractures served as controls. Results. The retrobulbar muscle volume was 2.1 ± 0.5 cm(3) (mean ± SD) in controls, 4.3 ± 1.5 cm(3) in GO without DON, and 4.7 ± 1.7 cm(3) in GO with DON. The retrobulbar fat volume was 5.4 ± 1.6 cm(3) in controls, 8.7 ± 8.0 cm(3) in GO without DON, and 9.4 ± 3.1 cm(3) in GO with DON. The muscle and fat volumes were higher in patients with GO than in controls (P < 0.001), but the volumes in orbits with and without DON were not significantly different. The volume of the optic nerve were similar in the 3 groups. The number of apical, coronal 2 mm thick slices with no fat was 2.9 ± 0.9 in normal orbits, it was 4.1 ± 1.0 in GO orbits without DON and 5.3 ± 0.8 in GO orbits with DON (P = 0.007). Conclusion. Apical muscle enlargement may be more important than orbital fat enlargement in the development of DON. However, the fact that apical crowding and muscle enlargement also occur in orbits without DON suggests that other factors also play a role in the development of DON. PMID:25101183

    Mass graves are complex products of large-scale crimes. Such scenes pose four conceptual challenges to investigators and forensic experts: the individual victim, the crime, the setting, and the statistical. Exhumation and post-mortem examination of mortal remains with associated personal and forensic evidence require integrated management of core forensic personnel including investigators, archaeologists, anthropologists, odontologists and pathologists, among whom there is overlapping expertise. The key to avoiding competition and ill-will among experts is to recognize that all such experts should be enabled to make known how their expertise matches with the temporal and spatial boundaries of victim, crime and setting. In turn, they should be apprised of where they fit into the overall judicial process and their limits within the investigation. Consequently, each expert requires access to the factual background of the case, to the site and its contents throughout the investigation. Each forensic team member has a responsibility to influence the investigation--throughout its course when possible--to make findings within their areas of expertise, and to make these available to the rest of the team so as to contribute most meaningfully to the aims of the investigation, both forensic and humanitarian. The on-site crime scene manager has an overarching role to enable integrated access to the complete scene and its contents by each forensic expert team member. In other words, the forensic scientist is given access and the ability to influence the investigation while control of evidence from the site as to identity and criminal activity are maintained by the crime scene manager. This contribution is directed at both the crime scene manager and each forensic expert; it describes the essential spatial and temporal parameters of an expert's opinion so as to encourage cooperation, and discourage conflict, within the forensic team.

    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' 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. PMID:27014188

    Objective The recurrence rate associated with antithyroid drug (ATD) treatment for Graves' disease (GD) is high compared with that for radioiodine therapy or surgery. It is important to identify patients in whom remission is unlikely, so that they are not given treatment that is destined to fail. The objective of this study was thus to evaluate factors influencing the prognosis of GD patients treated with ATDs. Patients One hundred and sixty-one patients were divided into two groups: 100 patients who could not discontinue ATDs for eight years or more (refractory group) and 61 patients who achieved remission within eight years after starting ATD treatment (nonrefractory group). The groups were compared in terms of age, thyroid function and thyroid-related autoantibodies at diagnosis, and the durations to the recovery of thyroid function and thyroid-related autoantibodies. Results The baseline levels of free triiodothyronine (T3), free thyroxine (T4), thyroid-stimulating antibodies (TSAbs) and thyroid-stimulating hormone (TSH) receptor antibodies (TRAbs) were high, and the age at diagnosis and the baseline level of thyroglobulin autoantibodies (TgAbs) were low in the refractory group compared with those in the nonrefractory group. The durations to the recovery of TSH, free T4, TRAb and TSAb levels were longer in the refractory group than in the nonrefractory group. No significant difference was observed with regard to thyroid peroxidase autoantibodies. Conclusion We compared the clinical features of these two groups in order to identify factors influencing the prognosis of GD patients treated with ATDs. A low baseline level of TgAbs is associated with the refractoriness of GD to ATD treatment. PMID:27301499

    Sialylation of cell components is an important immunomodulating mechanism affecting cell response to hormones and adhesion molecules. To study alterations in sialic acid metabolism in Graves' disease (GD) we measured the following parameters in various human thyroid tissues: lipid-bound sialic acid (LBSA) content, ganglioside profile, total sialyltransferase activity, and the two major sialyltransferase mRNAs for sialyltransferase-1 (ST6Gal I) and for sialyltransferase-4A (ST3Gal I). Fragments of toxic thyroid nodules (TN), nontoxic thyroid nodules (NN) and nontumorous tissue from patients with nodular goiter or thyroid cancer were used as a control (C). The LBSA content and sialyltransferase activity were the highest in the GD group (164 +/- 4.44 versus 120 +/- 2.00 nmoL/g, p = 0.005 and 1625 +/- 283.5 versus 324 +/- 54.2 cpm/mg of protein, p < 0.005 compared to control group C). Ganglioside profile in the GD group was similar to that in control tissues. Sialyltransferase- 1 mRNA and sialyltransferase-4A mRNA levels were significantly higher in the GD group than in the control group (12.52 +/- 6.90 versus 2.54 +/- 1.24 arbitrary units, p < 0.005 and 2,49 +/- 1.16 versus 1.23 +/- 0.46 arbitrary units, p < 0.05, respectively). There was a positive correlation between the increased sialyltransferase-1 mRNA level and the TSH-receptor antibody titer determined by the TRAK test. These results indicate that sialyltransferases expression and activity are increased in GD. Exact mechanism of this upregulation remains unknown, though one of possible explanations is the activation of the thyrotropin (TSH) receptor. PMID:16053379

    Context: There is no pathogenetically linked medical therapy for Graves' ophthalmopathy (GO). Lack of animal models and conflicting in vitro studies have hindered the development of such therapy. Recent reports propose that Graves' Igs bind to and activate thyrotropin receptors (TSHRs) and IGF-1 receptors (IGF-1Rs) on cells in orbital fat, stimulating hyaluronan (HA) secretion, a component of GO. Objective: The objective of the study was to investigate potential cross talk between TSHRs and IGF-1Rs in the pathogenesis of GO using a sensitive HA assay. Design/Setting/Participants: Orbital fibroblasts from GO patients were collected in an academic clinical practice and cultured in a research laboratory. Cells were treated with TSH, IGF-1, and a monoclonal Graves' Ig M22. Main Outcome Measures: HA was measured by a modified ELISA. Results: Simultaneous activation by TSH and IGF-1 synergistically increased HA secretion from 320 ± 52 for TSH and 430 ± 65 μg/mL for IGF-1 alone, to 1300 ± 95 μg/mL. IGF-1 shifted the TSH EC50 19-fold to higher potency. The dose response to M22 was biphasic. An IGF-1R antagonist inhibited the higher potency phase but had no effect on the lower potency phase. M22 did not cause IGF-1R autophosphorylation. A TSHR antagonist abolished both phases of M22-stimulated HA secretion. Conclusions: M22 stimulation of HA secretion by GO fibroblasts/preadipocytes involves cross talk between TSHR and IGF-1R. This cross talk relies on TSHR activation rather than direct activation of IGF-1R and leads to synergistic stimulation of HA secretion. These data propose a model for GO pathogenesis that explains previous contradictory results and argues for TSHR as the primary therapeutic target for GO. PMID:25485727

    We often recommend total thyroidectomy for patients with Graves' disease who wish to have a child in the near future in order to prevent fetal or neonatal hyperthyroidism, especially if the patients' serum thyrotropin receptor antibody (TRAb) values are high. The aim of this study was to analyze changes in serum TRAb values using a quantitative third-generation assay after total thyroidectomy and the half-lives of serum TRAb values to estimate the postoperative time needed to achieve the safe TRAb value for mothers. We retrospectively examined the records of 45 Graves' disease patients who underwent a total thyroidectomy and had high serum TRAb values. We also evaluated factors that prolonged the postoperative reduction of serum TRAb values. The serum TRAb values decreased rapidly in most of the patients, especially within the early postoperative (3-month) period. The presence of Graves' ophthalmopathy (GO) (p=0.001), smoking (p=0.004), and serum thyroglobulin values > 0.5 ng/mL at postoperative 12 months (p=0.039) were significantly associated with prolonged half-lives of the serum TRAb values. The median TRAb value half-life was 93.5 days in the patients without GO or smoking, 162.5 days in the patients with GO or smoking, and 357.4 days in the patients with both GO and smoking. Our findings indicate that using the half-life of patients' serum TRAb values determined by this third-generation assay would be effective to evaluate the reduction of serum TRAb values after total thyroidectomy and to estimate the postoperative time needed to achieve the maternal safe value.

    There are many potential purposes served by the investigation of human remains: criminal fact-finding, archaeological exploration, forensic research, and others. This paper focuses on the identification of remains from mass graves to find missing persons. The primary goal of such efforts is to honor the memory of the dead by bringing closure to living family members, thus supporting the human rights of both the living and the deceased. Cultures, customs, political, and interpersonal specifics will vary, but that singular goal should remain the central guiding principle. This article presents ethical and practical issues resulting from efforts to locate, exhume, and identify the remains of mass fatalities. PMID:12808715

    A 47-year-old woman presented with the complaints of nausea, vomiting, and weight loss. She had a history of bilateral surrenalectomy due to Cushing's syndrome. On examination she had tachycardia and orthostatic hypotension. Laboratory examinations revealed hypercalcemia and suppressed parathyroid hormone levels. She also had thyrotoxicosis due to Graves' disease. The investigations to rule out a malignancy were negative. With steroid, zoledronic acid, and antithyroid drug treatment her symptoms were resolved and calcium level was normalized. This case highlights the importance of recognizing thyrotoxicosis and concomitant adrenal failure as a possible cause of severe hypercalcemia. PMID:25878906

    2015-01-01

    Objective Graves' ophthalmopathy (GO) is an inflammatory disease in the orbital region. The first-line medical treatment is glucocorticoids. An important potential side effect of glucocorticoid treatment is suppression of the hypothalamic-pituitary-adrenal (HPA) axis with impairment of endogenous cortisol production, implicating symptoms of adrenocortical insufficiency, especially in the period after cessation of therapy with possible risks in cases of intercurrent illness. The aim of this study was to evaluate HPA axis function before and after methylprednisolone pulse treatment of GO. Study Design HPA axis function was evaluated by measurements of plasma ACTH and an ACTH stimulation test with plasma cortisol measurements at 0 and 30 min after an intravenous bolus of synthetic ACTH (Synacthen® 250 µg). This was done in 12 patients with GO before and at cessation of methylprednisolone pulse treatment (500 mg i.v. per week for 6 weeks followed by 250 mg i.v. per week for an additional 6 weeks). Results All patients included fulfilled the criteria of intact HPA axis function before and at cessation of methylprednisolone pulse treatment. Data are given as medians (with ranges). Before glucocorticoid treatment basal plasma cortisol was 290 nM (196-579) and 786 nM (612-1,050) after ACTH stimulation. At cessation of therapy the corresponding values were 309 nM (88-718) and 852 nM (524-1,011), respectively. Thus, all patients passed a 30-min stimulated plasma cortisol of 500 nM. Before treatment plasma ACTH was 4.2 pmol/l (4-16) and at cessation of therapy the corresponding value was 4.8 pmol/l (2-9; p = 0.27). Conclusion Transient suppression of the HPA axis with secondary adrenocortical insufficiency does not seem to be a common phenomenon after intravenous methylprednisolone pulse therapy for GO. Therefore, routine precautions are not necessary. However, our results do not exclude that transient secondary adrenocortical insufficiency might occur occasionally. PMID

    Context Thyroid associated ophthalmopathy (TAO) is a common and debilitating manifestation of Graves disease (GD). Presently little is known about factors that may increase the risk of developing TAO among patients with GD. Objective The purpose of this study is to identify risk factors associated with the development of TAO among individuals who are newly-diagnosed with GD. Design, Setting, Patients In this longitudinal cohort study, all beneficiaries age ≥ 18 years with newly-diagnosed GD who were continuously enrolled in a large nationwide U.S. managed care network and who had ≥1 visit to an eye care provider from 2001–2009 were identified. International Classification of Diseases (ICD-9-CM) billing codes were used to identify those who developed manifestations of TAO. Multivariable Cox regression was used to determine the hazard of developing TAO among persons who were newly-diagnosed with GD, with adjustment for sociodemographic factors, systemic medical conditions, thyroid stimulating hormone levels, and medical and surgical interventions for management of hyperthyroidism. Main Outcome Measure Hazard ratios (HR) with 95% confidence intervals (95% CIs). Results Of 8,404 patients with GD who met the inclusion criteria, 740 (8.8%) developed TAO (mean follow-up, 374 days since initial GD diagnosis). After adjustment for potential confounders, surgical thyroidectomy, alone or in combination with medical therapy, was associated with a 74%-decreased hazard for TAO (adjusted HR, 0.26 [95% CI, 0.12–0.51]), compared with radioactive iodine therapy alone. Statin use (for ≥60 days in the past year, vs. <60 days or nonuse) was associated with a 40%-decreased hazard (HR, 0.60 [CI, 0.37–0.93]). No significant association was found for use of non-statin cholesterol-lowering medications or COX-2 inhibitors and development of TAO. Conclusion and Relevance If prospective studies can confirm our finding that thyroidectomy and statin exposure are associated with

    Hyperthyroid patients exhibit accelerated bone loss by increased bone turnover, and normalization of thyroid function is associated with a significant attenuation of increased bone turnover, followed by an increase in bone mineral density. However, of patients with Graves' disease (GD) maintained on antithyroid drug (ATD) treatment, some exhibit persistent suppression of TSH long after normalization of their serum free T3 (FT3) and free T4 (FT4) levels. The aim of this study was to examine whether bone metabolism is still enhanced in TSH-suppressed premenopausal GD patients with normal FT3 and FT4 levels after ATD therapy (n = 19) compared with that in TSH-normal premenopausal GD patients (n = 30), and to evaluate the relationship between serum TSH receptor antibody (TRAb), an indicator of disease activity of GD, and various biochemical markers of bone metabolism. No difference was found between the two groups in serum Ca, phosphorus, or intact PTH, or in urinary Ca excretion. Serum bone alkaline phosphatase (B-ALP), bone formation markers, and urinary excretions of pyridinoline (U-PYD) and deoxypyridinoline (U-DPD), which are bone resorption markers, were significantly higher in the TSH-suppression group than in the TSH-normal group (B-ALP, P < 0.05; U-PYD, P < 0.001; U-DPD, P < 0.001). For the group of all GD patients enrolled in this study, TSH, but neither FT3 nor FT4, exhibited a significant negative correlation with B-ALP (r = -0.300; P < 0.05), U-PYD (r = -0.389; P < 0.05), and U-DPD (r = -0.446; P < 0.05), whereas TRAb exhibited a highly positive and significant correlation with B-ALP (r = 0.566; P < 0.0001), U-PYD (r = 0.491; P < 0.001), and U-DPD (r = 0.549; P < 0.0001). Even in GD patients with normal TSH, serum TRAb was positively correlated with B-ALP (r = 0.638; P < 0.001), U-PYD (r = 0.638; P < 0.001), and U-DPD (r = 0.641; P < 0.001). In conclusion, it is important to achieve normal TSH levels during ATD therapy to normalize bone turnover. TRAb was

    We studied the A/G single nucleotide polymorphism (SNP) at position 49 in exon 1 of the cytotoxic T lymphocyte-associated molecule-4 gene in 148 Chinese Graves' disease (GD) patients and 171 controls. Our primary aim was to test for the association of this SNP with the relapse of the hyperthyroidism after antithyroid withdrawal. Our secondary aim was to investigate the relationship between GD patients and controls according to the SNP genotypes. All GD patients were divided into the following three groups according to the time of relapse after drug discontinuation: group 1, early relapse within 9 months; group 2, relapse between 10 and 36 months; and group 3, relapse 3 or more years after discontinuation of treatment. There was a significant difference of genotype frequencies (P < 0.001) and allele frequencies (P < 0.001) among the three groups of patients. The frequency of the G/G genotype decreased from 79% to 64% and 39% in groups 1, 2, and 3, respectively. Compared with controls, a strong association (P < 0.001) of G allele was found for group 1, and moderate significance (P = 0.04) was found for group 2, but no association (P = 0.33) was found for group 3. At the end of treatment, the percentage of patients with persistent TSH-receptor antibody was statistically different (A/A, 9.0%; A/G, 20.8%; G/G, 45.5%; P = 0.004). Using 3 yr as the cutoff point for multivariate logistic regression analysis, we found that the G/G genotype (adjusted odds ratio, 3.1 compared with A/G plus A/A; 95% confidence interval, 1.3-7.1), larger goiter size at the end of treatment, and positive TSH-receptor antibody at the end of treatment were independent risk factors of recurrence. We conclude that the A/G polymorphism of the cytotoxic T lymphocyte-associated molecule-4 gene affects the progress of GD. The G/G genotype is associated with poor outcome. PMID:14715845

    Cigarette smoking has been reported to alter relapse rate in patients with Graves' disease (GD). However, the predictive effect of smoking in GD patients after withdrawal of antithyroid drug treatment (ATDT) is still controversial. A prospective multicenter trial has previously identified smoking as an independent risk factor for relapse. Based on this study, the present paper gives a more detailed analysis of the impact of smoking on the long-term course of GD after ATDT withdrawal. To this end, 86 smokers and 177 non-smokers were followed during two years after ATDT cessation. At the end of ATDT (visit 1) and four weeks later (visit 2) smokers had significant higher TSH receptor antibody (TRAb) levels than non-smokers (10.0 IU/L+/-1.6; mean+/-SEM vs. 6.4 IU/L+/-0.9; 11.0 IU/L+/-1.8 vs. 6.8 IU/L+/-0.8, p < 0.01, respectively). During follow-up, Kaplan Meier analysis showed a significantly higher relapse rate in smokers than non-smokers. A subset of GD patients with TRAb levels >10 IU/L had the highest risk to develop relapse during follow-up. Among them, smokers more often relapsed than non-smokers irrespective of TRAb levels, p < 0.01. Thus, in smokers with TRAb levels > or =10 IU/L the predictive values of a positive and negative test for relapse was 68% and 73%, respectively (specificity 95%). In conclusion, we identified two effects by which smoking alters the course of GD. First, smoking is implicated to elevate TRAb levels and therefore increase the risk for relapse during follow-up. Second, smoking is an independent risk factor to worsen the clinical course of both, GD patients with low and high immunological risk to experience relapse after a successful outcome of ATDT. Thus, our data suggest that smoking has modifying immunological consequences and an adverse impact on the course of GD after withdrawal of ATDT. Therefore, patients should be encouraged to stop smoking. PMID:17039420

    The meteorite Graves Nunataks 06128/06129 is a rare example of felsic asteroidal crust. Knowledge of its history can help shed light on the evolution processes of planetesimals. The noble gases can be used to constrain both the chronology of meteorites and the processes that result in movements of volatile elements on asteroidal bodies. We have examined the I-Xe and Ar-Ar systems of the plagioclase-rich achondrite, Graves Nunataks 06129 by high-resolution laser step-heating of irradiated samples. Iodine and 129Xe∗ are both present but are released at different temperatures and do not show a correlation, therefore the I-Xe system in GRA 06129 has no chronological significance. We propose that radiogenic 129Xe∗ was lost from primary phases and parentless 129Xe∗ was later introduced into the rock by interaction with a fluid sourced from a reservoir that evolved with a high I/Xe ratio. This could have been the same halogen-rich fluid that induced the conversion of merrillite and pyroxene into chlorapatite. Inherited 40Ar (i.e. not generated by in situ decay of 40K) is also present in one of three fragments studied here and may have been introduced at the same time as parentless 129Xe∗.

    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. PMID:24304615

    The aim of research is to arrange the results of ultrasonic and cytological researches during long-term drug treatment (more than 1 year) of patients with Graves' disease. From 2008 to 2013 the detailed examination of 220 patients was carried out in Kyiv City Centre for Endocrine Surgery which operates on the basis of the 3d Clinical Hospital. There were established three kinds of echographic patterns which pointed out the ultrasonic changes of the thyroid gland tissue, occurred during the drug treatment. Among 63 (28.6%) patients with long-term drug treatment the development of space-occupying lesions, occurred due to long duration of disease with long-term usage of tyreostatics, was recorded. After the surgical treatment the extracted thyroid gland tissue was subjected to histological study. The papillary carcinoma of thyroid gland was verified in 4 (6,3 %) of 63 patients with space-occupying lesions. The ultrasonic research of thyroid gland in combination with aspiration puncture biopsy and cytological research are the highly informative methods of examination of patients with Graves' disease which allow to objectify the organ structural condition while the disease duration.

    The aim of the study was to describe the typical sonographic features of the thyroid gland in patients with Graves' hyperthyroidism after radioiodine therapy (RIT). Thirty patients (21 female and 9 male) with a mean age of 53 y (standard deviation [SD] ± 11.3) and with previous Graves' disease who had been successfully treated with RIT were enrolled in the study. All were hypothyroid or euthyroid after treatment. The thyroid ultrasound was carried out by a single experienced operator with an 8-MHz linear transducer. Volume, vascularity, echogenicity and echotexture of the glands were noted. The presence of nodules and lymph nodes was also documented. The mean volumes of the right lobe were 2.4 mL ± 2.9 SD (0.6-14) and the left lobe were 1.8 mL ± 1.9 SD (0.4-9.1), with a mean total volume of 4.2 mL ± 4.7 SD (1.3-19.1). Of those who had a pre-treatment ultrasound (23%), the percentage reduction in volume was 87% (p < 0.05); 93% of the glands were hypovascular, with the remaining 7% showing normal vascularity. The glands were hyperechoic and of coarse echotexture. Overall, the sonographic features of the post-RIT gland included a significantly reduced mean total volume of 4.2 mL, hypovascularity, coarse echotexture and hyperechogenicity. PMID:26603660

    Graves` ophthalmopathy is a distressing autoimmune disease of unknown etiology. Analysis of the genes for antibodies secreted by orbital tissue-infiltrating plasma cells might provide insight into the pathogenesis of this disease. The authors, therefore, constructed an immunoglobulin heavy (H) chain and an immunoglobulin k light (L) chain cDNA library from the orbital tissue of a patient with active Graves` ophthalmopathy. Analysis of 15 H (IgG1) and 15 L (k) chains revealed a restricted spectrum of variable region genes. Fourteen of 15 variable k genes were about 94% homologous to the closest known germline gene, KL012. Thirteen of 15 H chain genes were 91% and 90% homologous to the closest germline genes, DP10 and hv1263, respectively. Remarkably, these germline genes also code for other autoantibodies to striated muscle (KL012) and thyroid peridase (KL012 and hv1263). These studies raise the possibility that particular germline genes may be associated with autoimmunity in humans. Further, the present study opens the way to identifying ocular autoantigens that may be the target of an humoral immune response. 29 refs., 4 figs., 1 tab.

    The effects of methimazole or betamethasone therapy on the TSH receptor antibody response to radioiodine therapy were compared in a prospective randomized study of 60 patients with hyperthyroidism due to Graves' disease. The patients were followed for 1 yr after treatment with 131I. Twenty-three patients received 131I alone, 17 were treated with methimazole for 2 months before and 3 months after 131I therapy, and 20 patients were treated with betamethasone for 3 weeks before and 4 weeks after 131I therapy. 131I induced a transient rise in the mean serum level of TSH receptor autoantibodies, measured as TSH binding inhibitory immunoglobulin (TBII), but in patients receiving methimazole treatment, no such rise occurred. In the betamethasone-treated patients, TBII increased similarly to that in patients treated with 131I alone. In addition, in patients given betamethasone, there was an early decrease in total serum immunoglobulin G, which persisted throughout the follow-up period. In the other 2 groups, no changes in total immunoglobulin G were found. The results demonstrate that in hyperthyroid Graves' disease, TBII production is influenced by therapy. Methimazole abolished the 131I-induced increase in TBII, whereas betamethasone did not have such an inhibitory effect.

    In this paper we present textural and mineral chemistry data for a PGM inclusion assemblage and whole-rock platinum-group element (PGE) concentrations of chromitite from Harold's Grave, which occurrs in a dunite pod in a mantle tectonite at Unst in the Shetland Ophiolite Complex (SOC), Scotland. The study utilized a number of analytical techniques, including acid digestion and isotope dilution (ID) ICP-MS, hydroseparation and electron microprobe analysis. The chromitite contains a pronounced enrichment of refractory PGE (IPGE: Os, Ir and Ru) over less refractory PGE (PPGE: Rh, Pt and Pd), typical of mantle hosted `ophiolitic' chromitites. A `primary' magmatic PGM assemblage is represented by euhedrally shaped (up to 60 μm in size) single and composite inclusions in chromite. Polyphase PGM grains are dominated by laurite and osmian iridium, with subordinate laurite + osmian iridium + iridian osmium and rare laurite + Ir-Rh alloy + Rh-rich sulphide (possibly prassoite). The compositional variability of associated laurite and Os-rich alloys at Harold's Grave fit the predicted compositions of experiment W-1200-0.37 of Andrews and Brenan (Can Mineral 40: 1705-1716, 2002) providing unequivocal information on conditions of their genesis, with the upper thermal stability of laurite in equilibrium with Os-rich alloys estimated at 1200-1250 °C and f(S2) of 10-0.39-10-0.07.

    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. PMID:27042408

    Graves' ophthalmopathy is an inflammatory autoimmune disease of the orbit, characterized by inflammation and proliferation of the orbital tissue caused by CD4+T cells and orbital fibroblasts. Despite recent substantial findings regarding its cellular and molecular foundations, the pathogenesis of Graves' ophthalmopathy remains unclear. Accumulating data suggest that microRNAs play important roles in the pathophysiology of autoimmunity and proliferation. Specifically, microRNA-155 (miR-155) can promote autoimmune inflammation by enhancing inflammatory T cell development. In contrast to miR-155, microRNA-146a (miR-146a) can inhibit the immune response by suppressing T cell activation. Furthermore, miR-155 and miR-146a are involved in cell proliferation, differentiation, and many other life processes. Thus, miR-155 and miR-146a, with opposite impacts on inflammatory responses carried out by T lymphocytes, appear to have multiple targets in the pathogenesis of Graves' ophthalmopathy. Our previous work showed that the expression of miR-146a was significantly decreased in peripheral blood mononuclear cells from Graves' ophthalmopathy patients compared with normal subjects. Accordingly, we proposed that the expression of miR-155 increased and the expression of miR-146a decreased in the target cells (CD4+T cells and orbital fibroblasts), thus promoting ocular inflammation and proliferation in Graves' ophthalmopathy. The proposed hypothesis warrants further investigation of the function of the differentially expressed microRNAs, which may shed new light on the pathogenesis of Graves' ophthalmopathy and lead to new strategies for its management.

    Background: In Graves' orbitopathy (GO), increased proliferation, excess adipogenesis, and hyaluronan overproduction produce GO exophthalmos. Enophthalmos occurs in some glaucoma patients treated with Bimatoprost (prostaglandin F2α, PGF2α) eye drops. We hypothesized that enophthalmos is secondary to reductions in orbital tissue proliferation, adipogenesis, and/or increased lipolysis. We aimed to determine which of these is affected by PGF2α by using the 3T3-L1 murine preadipocyte cell line and primary human orbital fibroblasts (OFs) from GO patients (n=5) and non-GO (n=5). Methods: 3T3-L1 cells and orbital OFs were cultured alone or with PGF2α (all experiments used 10−8 to 10−6 M) and counted on days 1/2/3 or 5, respectively; cell cycle analysis (flow cytometry) was applied. Adipogenesis (in the presence/absence of PGF2α) was evaluated (day 7 or 15 for 3T3-L1 and primary cells, respectively) morphologically by Oil Red O staining and quantitative polymerase chain reaction measurement of adipogenesis markers (glycerol-3-phosphate dehydrogenase and lipoprotein lipase, respectively). For lipolysis, in vitro–differentiated 3T3-L1 or mature orbital adipocytes were incubated with norepinephrine and PGF2α and free glycerol was assayed. Appropriate statistical tests were applied. Results: The population doubling time of 3T3-L1 was 27.3±1.4 hours—significantly increased by dimethyl sulfoxide 0.02% to 44.6±4.8 hours (p=0.007) and further significantly increased (p=0.049 compared with dimethyl sulfoxide) by 10−8 M PGF2α to 93.6±19.0 hours, indicating reduced proliferation, which was caused by prolongation of G2/M. GO OFs proliferated significantly more rapidly than non-GO (population doubling time 5.36±0.34 or 6.63±0.35 days, respectively, p=0.035), but the proliferation of both was significantly reduced (dose dependent from 10−8 M) by PGF2α, again with prolongation of G2/M. Adipogenesis in 3T3-L1 cells was minimally affected by PGF2α when assessed

    Basaltic eucrites, members of the HED achondrite clan, are thought to derive from the asteroid 4-Vesta [1]. Most eucrites show little compositional and petrographic variability, thus anomalous eucrite could provide key insights into differentiation processes that operated on Vesta. The eucrite Graves Nunataks (GRA) 98098 is an unbrecciated eucrite with cross cutting white tabular veins consisting of mainly equigranular tridymite and euhedral plagioclase with some pyroxene [2]. In addition, GRA has the second highest modal (volume) abundance of apatite in a eucrite studied thus far. The apatite is associated with the veins [2]. The GRA bulk rock composition is enriched in incompatible elements with concentrations ca. 3-5 times higher than in most basaltic eucrites [3]. Additionally, GRA has 10-20 times more Cl than any other analyzed eucritic apatite [2]. Here we measured the trace-element concentrations of plagioclase and pyroxene by laser ablation ICP-MS and the D/H ratio of the apatites by SIMS. In the domains of GRA cut by veins, the trace elements in plagioclase and pyroxene show an up to 15x enrichment in incompatible elements compared to other basaltic eucrites [4]. Here we report the first D/H measurement of any magmatic material from Vesta. The D/H of apatite in GRA is relatively light compared to vSMOW. Based on the high abundance of incompatible elements in GRA and the high Cl content found in apatites, Sarafian et al. [2] suggested that GRA could be akin to Lunar KREEP (lunar rocks enriched in K, REEs and P). With the additional evidence of enriched incompatible elements in plagioclase and pyroxene and the similarity in D/H compared to KREEP, it is likely that GRA was infiltrated by a late-stage melt enriched in incompatible elements, similar to Lunar KREEP. Further study is needed to determine if this late-stage melt formed in a similar manner as KREEP. 1. Consolmango, G.J. and M.J. Drake, Composition and evolution of the eucrite parent body: Evidence

    Antithyroid drugs (ATDs) have been shown to attenuate the effectiveness of radioiodine (radioiodine ablation, RIA) therapy in Graves' disease. We undertook a study to look at the impact of iodine uptakes on the outcome of 131I therapy. To determine the effect of prior ATD use on the duration of time to achieve cure in patients with high vs intermediate uptake Graves' disease who received a fixed dose (15 mCi) of 131I radioiodine. In a retrospective study of patients with Graves' disease, 475 patients who underwent RIA were followed-up on a two-monthly basis with thyroid function tests. Of the 123 patients with a documented preablation RAIU and consistent follow-up it was observed that 40 patients had an intermediate RAIU (10–30%) and 83 subjects had a distinctly increased uptake (>30%). Successful cure was defined as the elimination of thyrotoxicosis in the form of low free thyroxin and rising TSH levels. When a standard dose of 15 mCi 131I was administered, a cure rate of 93% was achieved. The median duration of time to cure (TC) was 129 days. Surprisingly, a direct proportional linear relationship (R 2=0.92) was established between time to cure and radioiodine uptake (TC> 3 0%=172days, TC10 – 3 0%=105 days, P<0.001). Patients who used ATD medications took a proportionately longer duration to achieve remission (TCNO ATD=102days, TCATD=253days, P<0.001). The effect of prior ATD therapy in delaying remission was amplified in the subset of patients with higher uptakes (TC> 3 0% + ATD=310days, TC> 3 0% + NO ATD=102days, P<0.001) compared to those with the intermediate uptakes (TC10 – 3 0% + ATD=126 days, TC10 – 3 0% + NO ATD=99 days, P<0.001). RIA, using a dose of 15 mCi achieved a high cure rate. Higher uptakes predicted longer time to achieve remission, with prior ATD use amplifying this effect. PMID:26772754

    This paper deals with the problem of competence of the forensic expert opinions on the exposure to "direct danger of death or grave detriment to health". According to the analysis of judicial verdicts and the comments of lawyers "direct danger" depends closely on the probability, time and number of occurrences between the behavior of the perpetrator and the threatening act. The competence of the forensic expert does not allow for the legal qualification of the act but for the assessment of from the medicolegal point of view, defining the threat and possible outcomes in a descriptive fashion. The assessment of "direct danger" should be the result of close cooperation between the judicial representative and forensic expert. PMID:15984124

    We report a case of 12-year-old girl with Graves' disease who had presented with deterioration in physical and scholastic performances since 10 years of age. She had an episode of atonic seizure and difficulty in speech. Brain MRI revealed formation of moyamoya vessels and a lesion suggestive of ischemic changes in the left frontal lobe. Because of uncontrollable thyrotoxicosis with anti-thyroid drug, she received a subtotal thyroidectomy. Two months later, she received a shunt operation between left superficial temporal artery and middle cerebral artery. The postoperative arterial spin-labeling MR imaging demonstrated an improvement of brain perfusion in left frontal lobe compared with the preoperative one, and provided comparable results of angiography and acetazolamide-challenged 150-gas PET. Thus, arterial spin-labeling MR imaging seems useful for follow-up evaluation of brain perfusion in qusai-moyamoya disease. PMID:25154228

    Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism, with recurrent muscle paralysis and hypokalemia that are caused by an intracellular shift of potassium. TPP is relatively common in Asian males, but is extremely rare in children and adolescents, even for those of Asian descent. We describe a 16-year-old Korean adolescent presenting with a two-week history of episodic leg weakness in the morning. He showed sinus tachycardia, lower leg weakness, and hypokalemia. Thyroid function test showed hyperthyroidism, and thyroid ultrasonography revealed a diffuse enlarged thyroid with increased vascularity, consistent with Graves' disease. He was treated with β-adrenergic blocker and antithyroid drugs. He has been symptom free for one year, as his hyperthyroidism has been controlled well with antithyroid drugs. TPP should be considered in children and adolescents with acute paralysis of the lower extremities and hypokalemia. PMID:25346923

    Calculation of the therapeutic activity of radioiodine 131I for individualized dosimetry in the treatment of Graves' disease requires an accurate estimate of the thyroid absorbed radiation dose based on a tracer activity administration of 131I. Common approaches (Marinelli-Quimby formula, MIRD algorithm) use, respectively, the effective half-life of radioiodine in the thyroid and the time-integrated activity. Many physicians perform one, two, or at most three tracer dose activity measurements at various times and calculate the required therapeutic activity by ad hoc methods. In this paper, we study the accuracy of estimates of four 'target variables': time-integrated activity coefficient, time of maximum activity, maximum activity, and effective half-life in the gland. Clinical data from 41 patients who underwent 131I therapy for Graves' disease at the University Hospital in Pisa, Italy, are used for analysis. The radioiodine kinetics are described using a nonlinear mixed-effects model. The distributions of the target variables in the patient population are characterized. Using minimum root mean squared error as the criterion, optimal 1-, 2-, and 3-point sampling schedules are determined for estimation of the target variables, and probabilistic bounds are given for the errors under the optimal times. An algorithm is developed for computing the optimal 1-, 2-, and 3-point sampling schedules for the target variables. This algorithm is implemented in a freely available software tool. Taking into consideration 131I effective half-life in the thyroid and measurement noise, the optimal 1-point time for time-integrated activity coefficient is a measurement 1 week following the tracer dose. Additional measurements give only a slight improvement in accuracy.

    A 2010 UK police search for a clandestine burial highlighted the need for more information and quantitative data to aid coastal beach searches. This study aimed to address this by establishing relevant forensic search methodologies to aid the search for clandestine coastal burial sites, using the North West English coastline as a search area. A set of parameters were established, including criteria such as tidal range, proximity to vehicular access points and distance from inhabited areas, which may inform forensic searches by prioritising likely locations of clandestine burials. Three prioritised coastal locations were subsequently identified: (1) coastal dunes at Formby, (2) coastal dunes and (3) beach foreshore at Southport, all sites part of the Liverpool City Region in the United Kingdom. At all locations, simulated clandestine graves were hand-dug by spades into which a naked adult-sized, metal-jointed fiberglass mannequin was buried at 0.5 m below ground level. Trial geophysical surveys were then undertaken with the aim of identifying the optimal geophysical instrumentation and technique to deploy in such environments. GPR data showed 450 MHz frequency antennae to be optimal, with significantly poor data obtained from the foreshore area due to saline seawater. Electrical resistivity and magnetic susceptibility surveys were successful in coastal environments in target detection (albeit not in non-vegetated sand dunes), with resistivity fixed-offset configurations deemed optimal. The latter survey successes may be due to the recent disturbed 'grave' rather than the target, which itself is of interest in terms of identifying the most recent clandestine burials. PMID:22285503

    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 < 0.001, paired t-test). 50 patients were included and follow-up time was 5.3 ± 1.2 years (mean ± SD). The QOL-scores increased 28 ± 35 and 26 ± 31 points, respectively, on the two subscales, "visual functioning" and "appearance" (mean ± SD). The patient satisfaction questionnaire showed that 88% of the patients would recommend 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. PMID:27159575

    The effects of betamethasone on thyroid autoantibody responses and outcome of radioiodine therapy were determined over a period of 1 yr in a prospective randomized study of 40 patients with Graves' disease. Twenty patients were given placebo tablets, and 20 patients were treated with betamethasone from 3 weeks before until 4 weeks after {sup 131}I therapy. At the time of inclusion in the study, the mean serum concentrations of TSH receptor antibodies, thyroid peroxidase antibodies, and thyroglobulin antibodies (TgAb) were increased in both groups. Three weeks of treatment with betamethasone reduced the thyroid peroxidase antibody and TgAb titers as well as the serum concentrations of thyroid hormones. A decrease in the TSH receptor antibody level was not statistically significant. After radioiodine therapy, transient increases in thyroid autoantibody levels were observed. The titers of the different antibodies generally changed in parallel. In some patients a detectable level of a given antibody was found only after the radioiodine treatment, and in two cases, TgAb did not appear at all, although the two other antibodies increased temporarily. Betamethasone delayed, but did not abolish, the {sup 131}I-induced antibody peaks. Betamethasone also caused a reduction in the total serum immunoglobulin G, a reduction which persisted throughout the study period. When the study ended, 17 patients given placebo and 9 patients given betamethasone were receiving replacement therapy due to the development of hypothyroidism. These patients at this point in time had lower antibody levels than those not requiring T4. The results of this study demonstrate that betamethasone reduces and modifies the thyroid autoantibody responses as well as the outcome of radioiodine therapy in patients with Graves' disease.

    Radioactive iodine-131 (RAI) has been reported to be associated with a high incidence of development or exacerbation of Graves` ophthalmopathy (GO). This is thought to be associated with a surge of autoantibodies after RAI therapy. The role of methimazole (MMI), which possesses immunomodulatory action, in the prevention of GO was explored by studying 114 patients with Graves` disease. They were assigned randomly to receive either RAI alone or adjunctive antithyroid drugs, which consisted of MMI and L-T{sub 4} as a block-replacement therapy for 12 months and were followed for 2 yr. Thirty-five patients (30.7%) had GO at presentation. Twenty-one (18%) patients developed new GO, and six had worsening of preexisting GO. The development of hypothyroidism (P < 0.01) and an elevation of TSH (P < 0.05) were associated with increased risk of development or exacerbation of GO. The chance of development or exacerbation of GO is higher in those with no ophthalmopathy than in those with preexisting GO at presentation (P = 0.002). The incidence of development or exacerbation of GO was similar in the two treatment groups (RAI, 22.8%; adjunctive antithyroid drugs, 23.7%; P = NS). MMI was able to suppress the surge of TSH receptor antibody (TRAB) after RAI, but a surge in TRAB was not of prognostic significance for the development of GO after RAI. Patients who developed or had exacerbation of GO actually had lower TRAB at presentation (P = 0.02). The authors conclude that hypothyroidism with elevated TSH is an important adverse factor for the development or exacerbation of GO, and MMI was unable to prevent the development or exacerbation of GO after RAI. 35 refs., 4 tabs.

    This paper describes molecular genetic identification of one third of the skeletal remains of 88 victims of postwar (June 1945) killings found in the Konfin I mass grave in Slovenia. Living relatives were traced for 36 victims. We analyzed 84 right femurs and compared their genetic profiles to the genetic material of living relatives. We cleaned the bones, removed surface contamination, and ground the bones into powder. Prior to DNA isolation using Biorobot EZ1 (Qiagen), the powder was decalcified. The nuclear DNA of the samples was quantified using the real-time polymerase chain reaction method. We extracted 0.8 to 100 ng DNA/g of bone powder from 82 bones. Autosomal genetic profiles and Y-chromosome haplotypes were obtained from 98% of the bones, and mitochondrial DNA (mtDNA) haplotypes from 95% of the bones for the HVI region and from 98% of the bones for the HVII region. Genetic profiles of the nuclear and mtDNA were determined for reference persons. For traceability in the event of contamination, we created an elimination database including genetic profiles of the nuclear and mtDNA of all persons that had been in contact with the skeletal remains. When comparing genetic profiles, we matched 28 of the 84 bones analyzed with living relatives (brothers, sisters, sons, daughters, nephews, or cousins). The statistical analyses showed a high confidence of correct identification for all 28 victims in the Konfin I mass grave (posterior probability ranged from 99.9% to more than 99.999999%).

    Orbital and pretibial fibroblasts are targets of autoimmune attack in Graves` ophthalmopathy (GO) and pretibial dermopathy (PTD). The fibroblast autoantigen involved in these peripheral manifestations of Graves` disease and the reason for the association of GO and PTD with hyperthyroidism are unknown. RNA encoding the full-length extracellular domain of the TSH receptor has been demonstrated in orbital and dermal fibroblasts from patients with GO and normal subjects, suggesting a possible antigenic link between fibroblasts and thyrocytes. RNA was isolated from cultured orbital, pretibial, and abdominal fibroblasts obtained from patients with severe GO (n = 22) and normal subjects (n = 5). RNA was reverse transcribed, and the resulting cDNA was amplified by the polymerase chain reaction, using primers spanning overlapping regions of the entire extracellular domain of the TSH receptor. Nucleotide sequence analysis showed an A for C substitution in the first position of codon 52 in 2 of the patients, both of whom had GO, PTD, and acropachy. Genomic DNA isolated from the 2 affected patients, and not from an additional 12 normal subjects, revealed the codon 52 mutation by direct sequencing and AciI restriction enzyme digestions. In conclusion, the authors have demonstrated the presence of a genomic point mutation, leading to a threonine for proline amino acid shift in the predicted peptide, in the extracellular domain of the TSH receptor in two patients with severe GO, PTD, acropachy, and high thyroid-stimulating immunoglobulin levels. RNA encoding this mutant product was demonstrated in the fibroblasts of these patients. They suggest that the TSH receptor may be an important fibroblast autoantigen in GO and PTD, and that this mutant form of the receptor may have unique immunogenic properties. 28 refs., 3 figs., 2 tabs.

    Activation of orbital fibroblasts resulting in excessive proliferation, cytokine and hyaluronan production and differentiation into adipocytes, is a main determinant of orbital tissue inflammation and tissue expansion in Graves' ophthalmopathy (GO). During the last years we have shown that the platelet-derived growth factor (PDGF) isoforms PDGF-AA, PDGF-AB and PDGF-BB are increased in orbital tissue from GO patients with active and inactive disease. These PDGF isoforms exhibit the capacity to stimulate proliferation, hyaluronan and cytokine/chemokine production by orbital fibroblasts. Moreover, PDGF-AB and PDGF-BB increase thyroid stimulating hormone receptor (TSHR) expression by orbital fibroblasts, which enhances the orbital fibroblast activating capacity of the THSR stimulatory autoantibodies present in Graves' disease (GD) patients. Of these PDGF isoforms PDGF-BB exhibits the strongest orbital fibroblast activating effects, which is likely related to its ability to bind both the PDGF-receptor (PDGF-R)α and PDGF-Rβ chains. Thus the PDGF-system fulfills important roles in orbital fibroblast activation in both active and inactive GO, which supports a therapeutic rationale for blocking PDGF signaling in GO. Tyrosine kinase inhibitors (TKIs) may be candidates to target PDGF signaling. Of several TKIs tested dasatinib exhibited the highest potency to block PDGF-R signaling in orbital fibroblasts and may represent a promising compound for the treatment of GO as it was effective at low dosage and is associated with less side effects compared to imatinib mesylate and nilotinib. In this review the contribution of PDGF to the pathophysiology of GO as well as therapeutic approaches to target this PDGF-system will be addressed. PMID:25759797

    Graves' (GD) hyperthyroidism leads to reduced bone mineral density (BMD) accompanied by accelerated bone turnover. Ample studies have identified association between estrogen receptor (ESR1) gene polymorphism and decreased BMD and osteoporosis. In contrast, number of publications that link ESR1, BMD and Graves' disease is limited. The purpose of this study was to identify the association between ESR1 polymorphisms and BMD in premenopausal women with GD and to determine whether ESR1 polymorphic variants can predispose to GD. The study included 75 women aged 23-46 years with GD and 163 healthy controls. BMD was measured at lumbar spine and femoral neck. We investigated two SNPs in the ESR1 gene and analyzed genetic variants in the form of haplotypes reconstructed by statistical method. Three out of four possible haplotypes of the PvuII and XbaI restriction fragment length polymorphisms were found in GD patients: px (55.3 %), PX (33.3 %) and Px (11.4 %). Women homozygous for xx of XbaI and for pp of PvuII had the lowest BMD at lumbar spine. Moreover, the px haplotype predisposed to reduced lumbar BMD. No associations were observed for femoral neck BMD. No statistically significant relationship were found between ESR1 polymorphisms or their haplotypes and GD. These results indicate that the PvuII and the XbaI polymorphisms of ESR1 gene are associated with bone mineral density in premenopausal women with GD and may help to estimate the risk of bone loss particularly at lumbar spine. However, none of the ESR1 gene alleles predict the risk of GD in Polish female patients. PMID:21423915

    Graves' ophthalmopathy (GO) is a common manifestation of Graves' disease (GD); however, its pathogenesis is not well understood. Recently, the dysregulation of regulatory T cells (Tregs) has been thought to be closely associated with the pathogenesis and clinical symptoms of autoimmune disease. We therefore evaluated whether T cell subsets, including Tregs, are associated with GO pathogenesis and clinical symptoms. In this observational study we evaluated 35 GD patients with overt ophthalmopathy (GOs) and 28 patients without ophthalmopathy (non-GOs). Fifteen healthy euthyroid patients served as healthy controls (HCs). Peripheral blood mononuclear cells from GOs, non-GOs and HCs were analyzed for CD4, CD25, and FoxP3 expression using flow cytometry. We also evaluated their correlation with disease activity according to the clinical activity score (CAS) and magnetic resonance imaging (MRI) findings. Disease severity was evaluated using the NOSPECS score, and clinical progression of GO was followed for 24 weeks. The main outcome measures were the frequencies of FoxP3-positive and -negative CD4(+) CD25(+) T cells at study outset, namely Tregs and effector T cells (Teffs), respectively. GOs had higher frequencies of Teffs (30.8±8.4%) than non-GOs (19.4±7.1%) and HCs (22.7±7.9%). Notably, patients with improved GOs had lower frequencies of Tregs (5.8±1.1%) than patients with stable or deteriorated GOs (7.3±1.2%), although ophthalmic and radiological parameters were not significantly different at the start of the study. In conclusion, an expanded Teff population may be associated with GO pathogenesis. Additionally, decreased Tregs in peripheral blood may predict a good clinical outcome. PMID:27349268

    Information on genetic susceptibility to Graves' disease in African Americans is limited. We studied DRB1, DQB1, DRB3 subtypes, DQA1*0501, DQA1*0201, and CTLA-4 polymorphisms in 49 African American patients with adult onset Graves' disease and 47 racially-matched controls using PCR-based sequence-specific priming methods. There were no significant differences in DRB1 or DQB1 allelic frequencies or CTLA-4 polymorphisms between patients and controls. However, we found that the frequency of DRB3 was significantly increased in the patients (75.5% vs. 57.4%, P = 0.006, X2 = 3.52), especially for the DRB3*0202 subtype (53.1% vs. 23.4, P = 0.003, X2 = 8.91). In this one respect, the finding was in concordance with our previous observations in Caucasian patients with adult-onset Graves' disease. In addition, whereas the frequency of DQA1*0501 was increased (P = 0.018, X2 = 5.63) in our patients, the haplotype of DRB3/DQA1*0501, or DRB3*0202/DQA1*0501 was found to be more strongly associated (P = 0.008, X2 = 7.0; P = 0.0008, X2 = 11.34, respectively). These data suggest that DRB3*0202, particularly when found with DQA1*0501 in a haplotype is a susceptible gene(s) for Graves' disease in adult African Americans. Considering these data with those in Caucasian patients, our results would suggest that the primary Graves susceptible locus is likely DRB3 and not DRB1. PMID:10770195

    Graves' hyperthyroidism is caused by antibodies to the TSH receptor (TSHR) that mimic thyroid stimulation by TSH. Stimulating TSHR antibodies and hyperthyroidism can be induced by immunizing mice with adenovirus expressing the human TSHR A-subunit. Prior analysis of induced Graves' disease in small families of recombinant inbred (RI) female mice demonstrated strong genetic control but did not resolve trait loci for TSHR antibodies or elevated serum T4. We investigated the genetic basis for induced Graves' disease in female mice of two large RI families and combined data with earlier findings to provide phenotypes for 178 genotypes. TSHR antibodies measured by inhibition of TSH binding to its receptor were highly significantly linked in the BXD set to the major histocompatibility region (chromosome 17), consistent with observations in 3 other RI families. In the LXS family, we detected linkage between T4 levels after TSHR-adenovirus immunization and the Ig heavy chain variable region (Igvh, chromosome 12). This observation is a key finding because components of the antigen binding region of Igs determine antibody specificity and have been previously linked to induced thyroid-stimulating antibodies. Data from the LXS family provide the first evidence in mice of a direct link between induced hyperthyroidism and Igvh genes. A role for major histocompatibility genes has now been established for genetic susceptibility to Graves' disease in both humans and mice. Future studies using arrays incorporating variation in the complex human Ig gene locus will be necessary to determine whether Igvh genes are also linked to Graves' disease in humans. PMID:25051451

    Autoimmune thyroid disease associated with interferon therapy can manifest as destructive thyroiditis, Graves' Hyperthyroidism, and autoimmune (often subclinical) hypothyroidism, the latter persisting in many patients. There are scare reports of a single patient developing extremes of autoimmune thyroid disease activated by the immunomodulatory effects of interferon. A 60-year-old man received 48 weeks of pegylated interferon and ribavirin therapy for chronic HCV. Six months into treatment, he reported fatigue, weight gain, and slowed cognition. Serum thyroid stimulating hormone (TSH) was 58.8 mIU/L [0.27–4.2], fT4 11.1 pmol/L [12–25], and fT3 4.2 pmol/L [2.5–6.0] with elevated anti-TPO (983 IU/mL [<35]) and anti-TG (733 U/mL [<80]) antibodies. He commenced thyroxine with initial clinical and biochemical resolution but developed symptoms of hyperthyroidism with weight loss and tremor 14 months later. Serum TSH was <0.02 mIU/L, fT4 54.3 pmol/L, and fT3 20.2 pmol/L, with an elevated TSH receptor (TRAb, 4.0 U/L [<1.0]), anti-TPO (1,163 IU/mL) and anti-TG (114 U/mL) antibodies. Technetium scan confirmed Graves' Disease with bilateral diffuse increased tracer uptake (5.9% [0.5–3.5%]). The patient commenced carbimazole therapy for 6 months. Treatment was ceased following spontaneous clinical and biochemical remission (TSH 3.84 mIU/L, fT4 17pmol/L, fT3 4.5 pmol/L, and TRAb <1 U/L). This raises the need to monitor thyroid function closely in patients both during and following completion of interferon treatment. PMID:27042364

    Monoclonal antibodies that bind to the TSH receptor were obtained by an autoantiidiotypic approach in which immunization of BALB/c mice was performed with mixtures of bovine (b) and human (h) TSH. Two of 28 positive wells were selected for cloning and characterization: D2 and 4G11. Their antiidiotypic character was evidenced by TSH-inhibitable binding to affinity-purified polyclonal anti-TSH. The specificity of D2 and 4G11 for the hormone-binding region of the TSH receptor was demonstrated by several findings: 1) they inhibited the binding of (125I)iodo-bTSH to receptor in a dose-dependent manner; 2) their binding to partially purified thyroid plasma membranes could be completely inhibited by bTSH and hTSH; and 3) they inhibited the TSH-dependent growth and adenylate cyclase stimulation in FRTL-5 cells in a dose-dependent manner. By Western blot analysis of bovine thyroid membranes, D2 bound to a polypeptide of 188,000-195,000 mol wt under nonreducing conditions and 54,000-59,000 mol wt after treatment of membranes with beta-mercaptoethanol; the 4G11 epitope was undetectable. Scatchard analysis of the binding of 125I-labeled antibodies to receptor showed that 4G11 bound to a single site with a Kd of 5.7 X 10(-9) M, whereas D2 showed complex binding characterized by high affinity (Kd = 1.74 X 10(-11) M) and low affinity (Kd = 1.3 X 10(-8) M) sites. Binding studies in which D2 and 4G11 competed with each other for the TSH receptor showed mutual but unequal inhibition. The data suggest that portions of the D2 and 4G11 epitopes overlap, but that there is a high affinity binding site(s) for D2 for which 4G11 competes less effectively. The binding of D2 and 4G11 to TSH receptor was inhibited by monoclonal antibodies secreted by Graves' heterohybridomas, showing that D2 and 4G11 share characteristics with autoantibodies of Graves' disease.

    Almost all pre-Hispanic societies from Quebrada de Humahuaca (north-western Argentina) buried their defuncts in domestic areas, demonstrating the importance of death and its daily presence among the living. Presumably, the collective graves contained related individuals, a hypothesis that can be tested through the study of ancient DNA. This study analyzes autosomal and uniparental genetic markers in individuals from two archaeological sites in Quebrada de Humahuaca occupied during the Late Formative (1450-1050 BP) and Regional Developments I (1050-700 BP) periods. Mitochondrial and Y-chromosome haplotypes were compared in order to establish possible maternal and paternal relatedness. Genotypes for 15 autosomal STRs were used to calculate pairwise relatedness coefficients and pedigree probabilities. High kinship levels among individuals buried in the same graves were found in both sites. Although only two particular cases were analyzed, these results represent an important contribution to the study of mortuary practices in the region by means of ancient DNA. PMID:27346733

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

    Graves' disease is caused by stimulating autoantibodies against the thyrotropin receptor inducing uncontrolled overproduction of thyroid hormones. A Bridge Assay is presented for direct detection of these thyroid-stimulating immunoglobulins using thyrotropin receptor chimeras. A capture receptor, formed by replacing aa residues 261-370 of the human thyrotropin receptor with residues 261-329 from rat lutropin/choriogonadotropin receptor and fixed to microtiter plates, binds one arm of the autoantibody. The second arm bridges to the signal receptor constructed from thyrotropin receptor (aa 21-261) and secretory alkaline phosphatase (aa 1-519) inducing chemiluminescence. The working range of the assay is from 0.3 IU/l to 50 IU/l with a cutoff of 0.54 IU/l and functional sensitivity of 0.3 IU/l. Sensitivity and specificity are 99.8 and 99.1%, respectively, with a diagnostic accuracy of 0.998. The low grey zone is from 0.3-0.54 IU/l. The stimulatory character of the assayed antibodies is shown through a good correlation (r=0.7079, p<10(-7)) to serum T4 levels of untreated patients. In Graves' disease, titers are increased in associated eye disease. In 3 hypothyroid patients with sera positive in the thyrotropin receptor competition assay and in the blocking bioassay, antibodies are not detected by the Bridge Assay, while the monoclonal blocking antibody K1-70 was detected. In Hashimoto disease thyrotropin receptor autoantibodies are detected in some patients, but not in goiter. This Bridge Assay delivers good diagnostic accuracy for identification of Graves' disease patients. Its high sensitivity may facilitate early detection of onset, remission, or recurrence of Graves' disease enabling timely adaption of the treatment.Human genes: TSHR, Homo sapiens, acc. no. M31774.1.

    Proposal of success criteria for strabismus surgery for patients with Graves' orbitopathy (GO) based on a systematic review of the literature. We performed a systematic search of OVID MEDLINE, OVID Embase, the Cochrane Central Register of Controlled Trials (CENTRAL) and the publisher subset of PubMed, to identify studies reporting on success criteria of strabismus surgery in GO. In addition, we handsearched several orthoptic journals and proceedings of strabismological congresses. Of the 789 articles retrieved, 42 articles described success criteria for strabismus surgery in GO. Most studies defined success in terms of a subjective diplopia-free field in primary and down gaze. Almost half of the studies used a graded scale (excellent, good, acceptable and failure) to describe the outcome of surgery. Three of the eligible studies described a tool to quantify the field of single vision in detail. Quality of life was not reported as an outcome measure in any of the published studies. In conclusion, success criteria for strabismus surgery in patients with GO are poorly defined and no consensus is available. The lack of standardization hampers comparative studies and thus the search for the best surgical treatment for diplopia in patients with GO. Therefore, we propose strict success criteria including a tool for quantification of remaining diplopia plus a disease-specific quality of life questionnaire (the GO-QoL). PMID:25876459

    Background Thyrotoxic 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. Methods This 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. Results The 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). Conclusion The polymorphisms in the ADRB2, AR, and GABRA3 genes could not explain the genetic susceptibility to TPP in Korean men with GD. PMID:26676335

    This paper focuses on a little discussed part of Chilean history and the efforts to resolve Human Rights cases from the period 1973 to 1990. A case file is presented to illustrate the different stages, problems and solutions found in one particularly challenging case studied by the Special Unit of Identification of Detained and Missing (UEIDDDD) of the Human Rights Program of the Forensic Service, Chile, during the period 2006-2009. A major complication found in this example was the fact that the remains studied were commingled, and in addition, were mixed with remains that were not of medico-legal interest - deposited prior to and after the case in question, but within the same common grave. Multiple burials and the consequences of commingled skeletal human remains are reviewed, paying special attention to the roles that different agents related to these types of cases play, how they influence the decision making process and the outcomes that can be expected in commingled cases due to the complexities and challenges they present. Effective communication between prosecutors and forensic practitioners is vital to optimize the resources. Equally important is the relationship that is built between the practitioners and the victims' families regarding communication, information and expectations that both parties may have.

    Purpose. To evaluate the effect of en bloc lateral wall decompression with additional orbital fat resection in terms of exophthalmos reduction and complications. Methods. A retrospective, noncomparative case series study from 1999 to 2011 (chart review) in Graves' orbitopathy (GO) patients. The standardized surgical technique involved removal of the lateral orbital wall including the orbital rim via a lid crease approach combined with additional orbital fat resection. Exophthalmos, diplopia, retrobulbar pressure sensation, and complications were analyzed pre- and postoperatively. Results. A total of 111 patients (164 orbits) with follow-up >3 months were analysed. Mean exophthalmos reduction was 3.05mm and preoperative orbital pressure sensation resolved or improved in all patients. Visual acuity improved significantly in patients undergoing surgery for rehabilitative or vision threatening purposes. Preoperative diplopia improved in 10 patients (9.0%) but worsened in 5 patients (4.5%), necessitating surgical correction in 3 patients. There were no significant complications; however, one patient had slight hollowing of the temporalis muscle around the scar that did not necessitate revision, and another patient with a circumscribed retraction of the scar itself underwent surgical correction. Conclusions. The study confirms the efficiency of en bloc lateral wall decompression in GO in a large series of patients, highlighting the low risk of disturbance of binocular functions and of cosmetic blemish in the temporal midface region.

    We treated 187 patients who had Graves' disease with low-dose radioactive iodide (/sup 131/I), using a protocol that included a compensation for thyroid size. The incidence of early hypothyroidism (12 per cent) was acceptably low in the first year after /sup 131/I treatment, but we found a cumulative high incidence (up to 76 per cent) at the end of the 11th year. In contrast, the incidence of permanent hypothyroidism was relatively stable in 166 surgically treated patients, increasing from 19 to 27 per cent at the end of 11 years. Among 122 medically treated patients, only 40 per cent entered remission, and hypothyroidism developed in 2 per cent during the same period of follow-up. The long-term incidence of hypothyroidism in our patients treated with low-dose /sup 131/I therapy was much higher than that found in earlier studies using a comparable dose. Our study suggests that it will be difficult to modify therapy with /sup 131/I alone to produce both early control of thyrotoxicosis and a low incidence of hypothyroidism.

    The effects of subtotal thyroidectomy and radioactive iodine on thyroid-stimulating immunoglobulins, as measured by a receptor assay, more appropriately termed TSH binding inhibitory immunoglobulins (TBII), were studied in 74 patients with Graves' disease. Fourty-four patients received radioactive iodine therapy, while 30 were subjected to subtotal thyroidectomy. After radioactive iodine, more patients were TBII-positive (90.5% vs 81.8%) than before treatment, and the mean TBII index decreased dramatically, the maximum decrease being 3 months. The mean TBI index subsequently returned gradually to the pretreatment level. Subtotal thyroidectomy had a different effect on TBII activity. TBII indices were positive in 89.3% of these patients before any treatment but were positive in only 40% (12 patients) after antithyroid drugs had been given before surgery. After surgery, TBII indices remained positive in 7 patients, while the remaining 5 patients became TBII negative. Seventeen patients (56.7%) were TBII negative before operation and remained so after surgery. One patient who was TBII negative before operation became TBII positive 2 months after operation. Interestingly, postoperative relapse of hyperthyroidism occurred in 3 patients who were TIBII positive, while hypothyroidism occurred in patients who were TBII negative. Thus, the TBII activity after subtotal thyroidectomy might be an important factor in determining the outcome of surgery.

    Previous reports on the excretion of /sup 131/I into human breast milk have recommended discontinuance of breast feeding from 1 to 12 days following diagnostic tracer doses of /sup 131/I. Recent excretion models have calculated that breast feeding could safely resume 56 days following a 5 microCi (0.185 MBq) /sup 131/I maternal tracer dose. We studied a postpartum patient with Graves' disease following first an uptake dose of 8.6 microCi (0.317 MBq) and then for 38 days following a 9.6 mCi (355 MBq) therapy dose of Na/sup 131/I. We calculated from our data that although nursing could not be safely resumed for 46 days following the 8.6-microCi uptake dose, nursing could resume in this patient 8 days after a 100-nCi (3.7 KBq) dose. Extrapolating this data to impure /sup 123/I (p, 2n or p, 5n) we feel that standard 100-microCi (3.7 MBq) doses of either /sup 123/I preparation is not suitable if nursing is to be resumed.

    OX40/OX40L pathway plays a very important role in the antigen priming T cells and effector T cells. In the present study, we aimed to examine the involvement of OX40/OX40L pathway in the activation of autoreactive T cells in patients with Grave's disease (GD). We found that OX40 and OX40L were constitutively coexpressed on peripheral CD4(+) T cells from GD patients using flow cytometry analysis. The levels of OX40 and OX40L coexpression on CD4(+) T cells were shown to be correlated with TRAbs. Cell proliferation assay showed that blocking OX40/OX40L signal inhibited T cell proliferation and survival, which suggested that OX40/OX40L could enhance CD4(+) T cell proliferation and maintain their long-term survival in GD by self-enhancing loop of T cell activation independent of APCs. Confocal microscopy and coimmunoprecipitation analysis further revealed that OX40 and OX40L formed a functional complex, which may facilitate signal transduction from OX40L to OX40 and contribute to the pathogenesis of GD.

    Autoimmune Regulator (AIRE) is a transcriptional regulator that is crucial for establishing central tolerance as illustrated by the Mendelian Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED) syndrome associated with AIRE-inactivating recessive or dominant mutations. Polymorphisms in AIRE have been proposed to be implicated in genetic susceptibility to non-Mendelian organ specific autoimmune diseases. Because there is evidence that in predisposition to Graves' disease (GD) central tolerance is crucial, we investigated whether AIRE polymorphisms could modulate risk of GD. A case-control association study using 29 variants and conducted in 150 GD patients and 200 controls did not detect any significant association. This result is not exceptional: a systematic review of the literature, including GWAS, on the association of AIRE variants with organ specific autoimmune diseases did not show clear associations; similarly heterozygous recessive mutations are not associated to non-Mendelian autoimmunity. Dominant negative mutations of AIRE are associated to autoimmunity but as mild forms of APECED rather than to non-Mendelian organ specific autoimmunity. The lack of association of common AIRE polymorphisms with polygenic autoimmune diseases is counterintuitive as many other genes less relevant for immunological tolerance have been found to be associated. These findings give rise to the intriguing possibility that evolution has excluded functionally modifying polymorphisms in AIRE. PMID:27266815

    CONTEXTE : Un nouveau traitement anti-immunoglobuline E (anti-IgE) contre l’asthme, l’omalizumab, a été approuvé au Canada. OBJECTIF : Passer en revue les données fondamentales et cliniques sur l’omalizumab et examiner le rôle possible de ce médicament dans la prise en charge de l’asthme au Canada. MÉTHODOLOGIE : Une recherche documentaire a été effectuée dans MEDLINE afin de repérer les études menées de 1960 à 2006 sur l’omalizumab. La recherche a également porté sur les résumés de réunions scientifiques récentes dans le domaine des maladies respiratoires et des allergies; par ailleurs, toute donnée non publiée a été demandée au fabricant. Après avoir revu et résumé les données, un comité mixte constitué de spécialistes des maladies respiratoires et des allergies a rédigé un ensemble de recommandations relatives à l’utilisation de l’omalizumab. RÉSULTATS : L’omalizumab est un anticorps monoclonal humanisé qui se lie au domaine C epsilon 3 de la molécule d’IgE pour former des complexes immuns solubles qui sont éliminés par le système réticulo-endothélial. L’administration d’injections sous-cutanées espacées de deux ou de quatre semaines à la dose recommandée entraîne une diminution rapide des taux d’IgE circulantes libres. Lors de deux essais cliniques de phase III menés auprès de 1 405 adultes et adolescents atteints d’asthme modéré à grave qui recevaient des doses moyennes stables de corticostéroïdes en inhalation (CSI), l’omalizumab a diminué les taux d’exacerbation par rapport au placebo et a été associé à une amélioration des symptômes ainsi qu’à une épargne plus importante des corticostéroïdes. Dans un essai mené auprès de 419 patients atteints d’asthme grave non maîtrisé malgré l’utilisation de doses élevées de CSI et de la prise concomitante d’agonistes bêta-2 à action prolongée, les exacerbations graves étaient de 50 % moins fréquentes chez

    Antibodies to TSH receptors (TRAb) have great pathogenetic importance in the development and maintenance of hyperthyroidism in Graves' disease (GD). Measurement of their serum level could be of diagnostic and prognostic importance in autoimmune hyperthyroidism and in monitoring the efficiency of thyrosuppressive drug (TSD) treatment in GD. The aim of our study was to assess the sensitivity (SN), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of the TRAb assay in confirming the diagnosis and to define its prognostic value for remission duration in GD patients at the end of TSD treatment with thionamide derivatives, propylthiouracil or methimazole. We studied 99 patients, 65 female, 34 male, 18-76 years old; 52 GD patients and 47 as control group. We have studied frequency of relapses and remission duration in GD patients by a 2nd generation serum TRAb commercial kit. Our results showed that, the SN, SP, PPV and NPV of the TRAb test were 100%, 97%, 98% and 100%, respectively. Remission duration after TSD treatment was longer and relapses were fewer in GD patients with lower levels of TRAb before (P<0.01) and at the end of TSD treatment (P<0.05). In conclusion, our results suggest that serum TRAb is very sensitive and specific for confirming the diagnosis of GD. TRAb levels at the beginning of TSD treatment, above 5 IU/L gives 18% greater chance, and above 15 IU/L, 36% greater chance for remission, shorter than 6 months. PMID:19675869

    The Spanish Civil War (1936-1939) and posterior dictatorship (until 1970s) stands as one of the major conflicts in the recent history of Spain. It led to nearly two hundred thousand men and women executed or murdered extra-judicially or after dubious legal procedures. Nowadays, most of them remain unidentified or even buried in irretraceable mass graves across Spain. Here, we present the genetic identification of human remains found in 26 mass graves located in Northern Spain. A total of 252 post-mortem remains were analyzed and compared to 186 relatives, allowing the identification of 87 victims. Overall, a significant success of DNA profiling was reached, since informative profiles (≥ 12 STRs and/or mitochondrial DNA profile) were obtained in 85.71% of the remains. This high performance in DNA profiling from challenging samples demonstrated the efficacy of DNA extraction and amplification methods used herein, given that only around 14.29% of the samples did not provide an informative genetic profile for the analysis performed, probably due to the presence of degraded and/or limited DNA in these remains. However, this study shows a partial identification success rate, which is clearly a consequence of the lack of both appropriate family members for genetic comparisons and accurate information about the victims' location. Hence, further perseverance in the exhumation of other intact graves as well as in the search of more alleged relatives is crucial in order to facilitate and increase the number of genetic identifications.

    From studies of binding of 51Cr-labeled T cells to human thyroid monolayers, we have postulated the existence of tissue "homing-like" receptors on thyroid cells in patients with Graves' disease (GD). In this study we have investigated whether the CD44 (Hermes-1) protein, well known as a putative human lymphocyte homing receptor, is expressed on thyroid cells in patients with GD, and if so whether its expression is influenced by interferon-gamma (IFN-gamma). Cell surface CD44, as well as CD54 (ICAM-1), another putative homing receptor, antigens were analyzed by flow cytometry and immunohistochemistry. CD44 and CD54 were both expressed on thyroid cells from untreated patients with GD, which, in the case of CD44, appeared as two peaks. IFN-gamma treatment enhanced the expression of the CD54 protein on Graves' thyroid cells and inhibited the expression of the larger of the two CD44 peaks, but not the other. Only small amounts of CD44 and CD54 were detected on normal thyroid cells, neither of which was affected by IFN-gamma. The CD44 protein was also demonstrated on both GD and normal thyroid cells by immunohistochemistry. These findings suggest that CD44, and possibly CD54, may induce putative adhesion pathways that lead to the homing of lymphocytes to the thyroid in patients who develop Hashimoto's thyroiditis and Graves' disease.

    A 48-year-old woman was diagnosed and treated for Graves' disease (GD) in 1999 but she discontinued treatment at her own discretion. In 2011, she was admitted to a local hospital for management of thyrotoxic crisis. Treatment with propylthiouracil, iodide potassium (KI), and prednisolone (PSL) was started, which resulted in improvement of the general condition. PSL and KI were discontinued before she was transferred to our hospital. At the local hospital, fasting plasma glucose (FPG) was 212 mg/dL and hemoglobin A1c concentration was 11.2%; intensive insulin therapy had been instituted. Upon admission to our hospital, FPG level was 122 mg/dL, but insulin secretion was compromised, suggesting aggravation of thyroid function and deterioration of glycemic control. The FPG level increased to 173 mg/dL; continuous glucose monitoring (CGM) identified dawn phenomenon at approximately 0400 h. Resumption of KI resulted in improvement of FPG and disappearance of the dawn phenomenon, as assessed by CGM. These results indicate that in patients with compromised insulin secretion, hyperthyroidism can induce elevation of not only postprandial blood glucose, but also FPG level due to the dawn phenomenon and that the dawn phenomenon can be alleviated with improvement in thyroid function. To our knowledge, no studies have assessed glucose variability by CGM before and after treatment of Graves' disease. The observations made in this case shed light on the understanding of abnormal glucose metabolism associated with Graves' disease. PMID:24420389

    Serum thyroid hormone concentrations increase after radioiodine (RAI) therapy for Graves' disease. This phenomenon has been ascribed to either antithyroid drug withdrawal before RAI therapy or release of preformed thyroid hormones into the bloodstream from the RAI-damaged thyroid. Lithium blocks the release of iodine and thyroid hormones from the thyroid, thus enhancing the effectiveness of RAI therapy. Changes in serum-free thyroxine (FT4) and triiodothyronine (FT3) levels after methimazole (MMI) discontinuation and RAI therapy were evaluated in a prospective, randomized, control study of 36 patients with Graves' disease. After a 3- to 4-month course of MMI, patients were assigned to one of three groups: G1 (RAI alone); G2 (RAI plus lithium for 6 d starting on the day of RAI therapy); or G3 (RAI plus lithium for 19 d starting on the day of MMI withdrawal). G1-G2 patients had an increase in serum FT4 and FT3 levels from 13.5 +/- 6.5 to 19.8 +/- 9.2 pmol/liter and 5.0 +/- 2.0 to 8.0 +/- 4.8 pmol/liter, respectively (P < 0.0001), 2-5 d after MMI withdrawal, but G3 patients showed no changes. In the 30 d after RAI therapy, mean serum FT4 values increased in G1 patients (P = 0.02), peaking at 3-7 d (P < 0.05) but not in G2 and G3 patients. Serum FT3 levels decreased in G1, G2, and G3 (P = 0.03, P = 0.001, P = 0.02, respectively). Hyperthyroidism was cured in 8 of 12 G1 patients, 11 of 12 G2 patients, and 11 of 12 G3 patients (P = 0.31). Control of hyperthyroidism was prompter in G2 (P = 0.08) and G3 (P < 0.05) than in G1 patients. Patients in the three groups received a similar dose of RAI, but the committed radiation to the thyroid was higher in G3 (563 +/- 174 Gray) and G2 (588 +/- 347 Gray) than in G1 (429 +/- 204 Gray) (P < 0.03). In conclusion, the results of the present study demonstrate that: 1) MMI withdrawal is associated with a slight rise in serum thyroid hormone levels; 2) a further increase occurs after RAI therapy; 3) changes in serum thyroid hormone

    The aim of the present study was to assess the apparent diffusion coefficient (ADC) in diffusion-weighted imaging (DWI), thyroid radioactive iodine uptake (RAIU), thyroid scintigraphy and thyrotropin receptor antibody (TRAb) levels in the differential diagnosis between Graves' disease (GD) and painless thyroiditis (PT). A total of 102 patients with GD and 37 patients with PT were enrolled in the study. DWI was obtained with a 3.0-T magnetic resonance scanner, and ADC values were calculated. RAIU and thyroid scintigraphy were performed. Tissue samples were obtained from patients with GD (6 cases) following thyroidectomy, and from patients with PT (2 cases) following biopsy. Receiver operating characteristic (ROC) curves were drawn, optimal cut-off values were selected, and the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were assessed. It was found that the ADC, TRAb and RAIU were significantly higher in GD than in PT (P<0.05). ROC curves showed areas under the curves for RAIU, ADC and TRAb that were >0.900. RAIU was the reference method. Sensitivity, specificity, accuracy, PPV and NPV were 96.078, 91.892, 95.000, 97.059 and 89.474% for ADC, and 88.235, 75.676, 84.892, 90.909 and 70.000% for TRAb, after the optimal thresholds of 1.837×10−3 mm2/sec and 1.350 IU/ml were determined respectively. Histopathology showed that tissue cellularity in PT was much higher than in GD due to massive lymphocytic infiltration. The results of the present study indicate that RAIU, ADC and TRAb are of diagnostic value for differentiating between GD and PT. DWI has great potential for thyroid pathophysiological imaging because it reflects differences in tissue cellularity between GD and PT. PMID:26136954

    Background In Graves' thyrotoxicosis tachycardia, weight loss and mental symptoms are common. Recovery takes time and varies between patients. Treatment with methimazole reduces thyroid hormone levels. According to previous research, this reduction has been faster if selenium (Se) is added. Objective The objective was to investigate whether supplementing the pharmacologic treatment with Se could change the immune mechanisms, hormone levels and/or depression and anxiety. Methods We prospectively investigated 38 patients with initially untreated thyrotoxicosis by measuring the thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), thyroid receptor antibodies and thyroid peroxidase auto-antibodies before medication and at 6, 18 and 36 weeks after commencing treatment with methimazole and levo-thyroxine, with a randomized blinded oral administration of 200 µg Se/day or placebo. The selenoprotein P concentration was determined in plasma at inclusion and after 36 weeks. The patients were also assessed with questionnaires about depression, anxiety and self-rated symptoms before medication was started and after 36 weeks. Results FT4 decreased more in the Se group at 18 weeks (14 vs. 17 pmol/l compared to the placebo group, p = 0.01) and also at 36 weeks (15 vs. 18 pmol/l, p = 0.01). The TSH increased more in the Se group at 18 weeks (0.05 vs. 0.02 mIU/l, p = 0.04). The depression and anxiety scores were similar in both groups. In the Se group, the depression rates correlated negatively with FT3 and positively with TSH. This was not seen in the placebo group. Conclusions Se supplementation can enhance biochemical restoration of hyperthyroidism, but whether this could shorten clinical symptoms of thyrotoxicosis and reduce mental symptoms must be investigated further.

    The purpose of this study is to evaluate and compare the incidence of hypothyroidism following different fixed radioactive iodine-131 ((131)I) activities in the treatment of Graves' disease (GD) and to investigate the predictive factors that may influence its occurrence. This retrospective analysis was performed on 272 patients with GD who were treated with (131)I, among whom 125 received 370 MBq and 147 received 555 MBq. The outcome was categorized as hypothyroidism, euthyroidism, and persistent hyperthyroidism. Multiple logistic regression analysis was performed to identify significant risk factors that affect the development of hypothyroidism. The incidence of hypothyroidism following the first low activity was 24.8% with a high treatment failure rate of 58.4%, compared with 48.3% and 32% following high activity. The overall cumulative incidence of hypothyroidism following repeated activities was 50.7%, out of which 73.9% occurred after the first activity and 20.3% after the second activity. The higher (131)I activity (P < 0.001) and average and mild enlargement of the thyroid gland (P = 0.004) were identified as significant independent factors that increase the rate of incidence of hypothyroidism (Odds ratios were 2.95 and 2.59). No correlation was found between the development of hypothyroidism and the factors such as age, gender, presence of exophthalmos, previous antithyroid medications, and the durations, and Technetium-99m (Tc-99m) pertechnetate thyroid uptake. In view of the high treatment failure rate after first low activity and lower post high activity hypothyroid incidence, high activity is recommended for GD patients, reserving the use of 370MBq for patients with average sized and mildly enlarged goiter; this increases patient convenience by avoiding multiple activities to achieve cure and long-term follow-up.

    The aim of the work was to investigate the effect of early thyroidectomy on the course of active Graves' orbitopathy (GO) in patients with low probability of remission [high TSH receptor antibody (TRAb) serum levels, severe GO] compared to that of continued therapy with antithyroid drugs. Two cohorts were evaluated retrospectively (total n=92 patients with active GO, CAS≥4). Forty-six patients underwent early thyroidectomy (Tx-group) 6±2 months after initiation of antithyroid drug (ATD) therapy, while ATD was continued for another 6±2 months in the ATD-group (n=46). These controls were consecutively chosen from a database and matched to the Tx-group. GO was evaluated (activity, severity, TRAb) at baseline and at 6 month follow-up. At baseline, both cohorts were virtually identical as to disease severity, activity and duration, as well as prior anti-inflammatory treatment, age, gender, and smoking behavior. At 6 month follow-up, NOSPECS severity score was significantly decreased within each group, but did not differ between both groups. However, significantly more patients of the Tx-group presented with inactive GO (89.1 vs. 67.4%, * p=0.02), and mean CAS score was significantly lower in Tx-group (2.1) than in ADT-group (2.8; * p=0.02) at the end of follow-up. TRAb levels declined in both groups (Tx-group: from 18.6 to 5.2 vs. ATD-group: 12.8-3.2 IU/l, p0=0.07, p6months=0.32). Residual GO activity was lower in Tx-group, associated with a higher rate of inactivation of GO. This allows an earlier initiation of ophthalmosurgical rehabilitation in patients with severe GO, which may positively influence quality of life of the patients. PMID:27351809

    The association between the human leukocyte antigen (HLA) serotype DR3 and Graves` disease (GD) in Caucasian populations is well known. However, an even stronger association has been reported recently, especially in the male population, between the closely linked HLA allele DQA1*0501 and GD. We postulated that the reported association between DQA1*0501 and GD may be a result of the linkage of this allele with DR3 and may not represent an independent association. Accordingly, we screened a population of North American Caucasians (n=218), including patients with GD (n=101, 32 males, 69 females) and individuals with documented normal thyroid function (n=117, 51 males, 66 females), for the presence of the DQA1*0501 allele and those alleles corresponding to the DR3 serotype (DRB1*03). Screening was accomplished using sequence specific PCR. A significant association was documented in the total study population between DR3 positivity and GD (P=0.0002), but not between DQA1*0501 positivity and GD(P=0.06). After gender stratification, significant associations were found only in the female population (DR3, P=0.0004; DQA1*0501, P=0.012) and not in the male population (DR3, P=1.0;DQA1*0501,P=.0). Additionally, in those DR3 negative female subjects (n=100), there was no independent association between DQA1*0501 positivity (n=26) and GD (P=0.82). P-values were corrected, where appropriate, for gender stratification and/or the number of HLA alleles tested. In conclusion, our results demonstrated a lack of independent association between the presence of the HLA allele DAQ1*0501 and GD. We suggest that the apparent association between this allele and GD in the female population may be the result of its` close linkage to DR3. 21 refs., 7 tabs.

    Graves' disease (GD) is an autoimmune disease of the thyroid gland caused by autoantibodies against thyroid-stimulating hormone receptor (TSHR). Currently, the diagnostic test for TSHR autoantibodies is based on an indirect competitive binding assay that measures the ability of TSHR autoantibodies to inhibit the binding of thyroid-stimulating hormone (TSH) to TSHR. Here, we have developed a specific and direct diagnostic method for autoantibodies in GD that incorporates immobilized TSHR-containing recombinant proteoliposomes into an enzyme-linked immunosorbent assay (ELISA). To reduce non-specific binding of autoantibodies to recombinant proteoliposomes, we investigated the effect of polyethylene glycol (PEG)-lipid on the binding of commercially available anti-TSHR antibodies (aTSHRAb). The incorporation of PEG-lipids into liposomes decreased non-specific binding, as compared to liposomes that did not contain PEG-lipids, and the addition of blocking reagents further decreased non-specific reactivity. aTSHRAb exhibited higher reactivity towards PEG-modified TSHR recombinant proteoliposomes than PEG-modified liposomes without TSHR (bare liposomes). Importantly, serum autoantibodies from patients with GD, which is associated with hyperthyroidism, exhibited remarkably specific binding to TSHR recombinant proteoliposomes. Serum autoantibodies from patients with Hashimoto's disease (HD), which is associated with hypothyroidism, also reacted specifically with proteoliposomal TSHR. These results suggest that immobilized TSHR recombinant proteoliposomes can serve as a direct diagnostic test for GD and HD. Furthermore, given that there is no competition test currently available for detecting autoantibodies in HD, the combination of TSHR recombinant proteoliposome ELISA and indirect competitive TSHR binding assay might be an effective way to discriminate between GD and HD.

    Summary Les brûlés graves nécessitent une prise en charge multidisciplinaire dans des centres hautement spécialisés. La rareté de ces centres impose souvent le transport aérien médicalisé longue distance. Cependant, il y a peu de données publiées sur ces transferts. Dans cette mise au point, pour optimiser la prise en charge des brûlés dès qu’un transport aérien est décidé ou même seulement envisagé, nous proposons d’extraire de cette littérature limitée des principes simples s’appuyant aussi sur l’expérience pratique du Service de Santé des Armées françaises. Nous décrivons d’abord comment les contraintes aéronautiques peuvent affecter le transport de brûlés graves à bord d’aéronefs. Nous abordons ensuite la régulation de ces missions, en analysant les risques associés au transport aérien des brûlés graves et leurs implications sur les indications, la chronologie et les modalités du transport. Enfin, nous développons la conduite de la mission, comprenant la préparation du matériel et des consommables avant le vol, l’évaluation et la mise en condition du patient avant l’embarquement, et la poursuite de la prise en charge en vol.

    We examined the relationships existing between serum cytokine levels and bone mineral density (BMD) in women of premenopausal age affected by Graves' disease with subclinical hyperthyroidism. The study population consisted of 21 women with untreated hyperthyroid Graves' disease (group H) (age, 36 +/- 2 years), eight women with untreated subclinical hyperthyroid status (group SH) (age, 33 +/- 5 years) and 10 healthy women (group N) (age, 35 +/- 3 years). The following measurements were made in all patients: free T4 (fT4), free T3 (fT3), thyroid stimulating hormone (TSH), TSH receptor antibody (TRab), anti-thyroid peroxidase antibody (anti-TPO), anti-thyroglobulin antibody (anti-Tg), interleukin-2 receptor (IL-2r), interleukin-4 (IL-4), interleukin-8 (IL-8) and interleukin-13 (IL-13). IL-2r and IL-8 levels significantly increased in group H compared with group SH (p < 0.01 and p = 0.05, respectively) and group N (p < 0.001 and p = 0.02, respectively). IL-4 and IL-13 levels tended to be lower in groups H and SH compared with group N, although this difference did not reach statistical significance. Bone mineral density was significantly reduced in only two areas of the femur in group H compared with group N. There was no difference in BMD between groups SH and N. There was no correlation between thyroid hormones, serum cytokine levels and BMD in either group. In conclusion, these results suggest that there were no relationships existing between the serum level of these cytokines and BMD in women of premenopausal age affected by Graves' disease with subclinical hyperthyroidism.

    Immunization with adenovirus expressing the TSH receptor (TSHR) induces hyperthyroidism in 25-50% of mice. Even more effective is immunization with a TSHR A-subunit adenovirus (65-84% hyperthyroidism). Nevertheless, TSHR antibody characteristics in these mice do not mimic accurately those of autoantibodies in typical Graves' patients, with a marked TSH-blocking antibody response. We hypothesized that this suboptimal antibody response was consequent to the standard dose of TSHR-adenovirus providing too great an immune stimulus. To test this hypothesis, we compared BALB/c mice immunized with the usual number (10(11)) and with far fewer viral particles (10(9) and 10(7)). Regardless of viral dose, hyperthyroidism developed in a similar proportion (68-80%) of mice. We then examined the qualitative nature of TSHR antibodies in each group. Sera from all mice had TSH binding-inhibitory (TBI) activity after the second immunization, with TBI values in proportion to the viral dose. After the third injection, all groups had near-maximal TBI values. Remarkably, in confirmation of our hypothesis, immunization with progressively lower viral doses generated TSHR antibodies approaching the characteristics of autoantibodies in human Graves' disease as follows: 1) lower TSHR antibody titers on ELISA and 2) lower TSH-blocking antibody activity without decrease in thyroid-stimulating antibody activity. In summary, low-dose immunization with adenovirus expressing the free TSHR A-subunit provides an induced animal model with a high prevalence of hyperthyroidism as well as TSHR antibodies more closely resembling autoantibodies in Graves' disease.

    The results of an experimental study of a magnetically-kicked flexible-beam oscillator are presented. The dynamics of the autonomous system are observed using nine strain gauges distributed along the length of the beam. The Karhunen-Lo{grave e}ve decomposition is used to study the dimensionality of the system in terms of modal interactions. Two modes which interact to produce the observed dynamics over a wide range of the system{close_quote}s bifurcation parameter are found. It is concluded that a two degree of freedom model is adequate to describe the observed steady-state phenomena. {copyright} {ital 1996 American Institute of Physics.}

    Background Intreleukin-37 (IL-37), a member of IL-1 family, is primarily an anti-inflammatory cytokine, which reduces systemic and local inflammation. However, the expression and role of IL-37 in Graves' disease (GD) remains unknown. This study aims to measure the levels of serum and peripheral blood mononuclear cells (PBMCs) IL-37 in patients with Graves' disease and to examine its association with disease activity. Furthermore, we investigate the effect of IL-37 on proinflammatory cytokines involved in the pathogenesis of GD. Methods The expressions of IL-37, TNF-α, IL-6, and IL-17 mRNA in peripheral blood mononuclear cells (PBMCs) of 40 patients with Graves' disease were determined by real-time reverse transcription-polymerase chain reaction (RT-PCR), and the levels of IL-37, TNF-α, IL-6, and IL-17 in serum were detected by enzyme-linked immunoassay (ELISA). The correlation of serum IL-37 levels with cytokines and disease activity in Graves' disease patients were investigated. The expressions of cytokines TNF-α, IL-6, and IL-17 in PBMCs under recombinant IL-37 stimulation were determined by RT-PCR and ELISA respectively. Results The levels of IL-37, TNF-α, IL-6, and IL-17 in PBMCs and serum were significantly increased in patients with GD compared with healthy controls (HC). Serum IL-37 were closely correlated with TNF-α, IL-6, IL-17, thyrotropin (TSH), free thyroxine (FT4),free triiodothyronine (FT3) and thyrotropin receptor antibody (TRAB). GD patients with active disease showed higher IL-37 mRNA and serum protein levels compared with those with inactive disease as well as HC. Moreover, IL-37 suppressed the production of IL-6, IL-17 and TNF-α in PBMCs of patients with GD. Conclusions Increased level of IL-37 in patients with GD are associated with TNF-α, IL-6, IL-17 and disease activity, and it plays a protective role against inflammatory effect in GD by inhibiting the production of proinflammatory cytokines. Thus, IL-37 may provide a novel research

    Whether radioactive iodine treatment of Graves' disease (GD) during pregnancy will increase pregnancy loss and affect fetal development is still a matter of concern. From May 2005 to December 2015, 2,276 childbearing-age women with GD received iodine-131 treatment in our departments and were retrospectively enrolled in our study. When some of them were found to have been pregnant, their thyroid functions were measured every 4 weeks, in addition, thyroid-stimulating hormone (TSH) was measured 6 weeks after delivery. When necessary, levothyroxine or propylthiouracil (PTU) was given in order to control their TSH levels during pregnancy. Finally, 69 pregnant women (29 ± 3.5 years old) and 1346 women who were not pregnant during the follow-up period were enrolled into this study. They were all hyperthyroid before or during pregnancy. Among 69 pregnant women, the administrated amount of iodine-131 was 254.9 ± 99.9 MBq. Fifty patients became subclinically hypothyroid after treatment and were administrated levothyroxine (55 ± 25 μg/d). Seven patients were diagnosed with subclinical hyperthyroidism during pregnancy and they received PTU (25 ± 12.5 mg/d). Twelve patients with normal thyroid function were also clinically followed. Among 69 women, 63 had a single birth, 3 had dizygotic twins, 2 had two pregnancies and 1 had a single twin birth. Sixty five babies were born full-term, while 9 were premature (4 ± 1 weeks early) with birth weight 3.2 ± 0.5 kg. Six new born babies were considered to be low birth weight infants (< 2.5 kg) while 5 were high birth weight (> 4 kg), but the weights of all the infants were within the normal range. During the period of observation to December 2015, all the infants were found to grow and develop normally. Among 1346 women who were not pregnant were in the further follow-up. Our study found no detrimental effects of the iodine-131 treatment in the pregnant women or their offspring so far. PMID:27181740

    Graves' disease (GD) is characterized by the presence of autoantibodies against the TSH-receptor (TSH-R) which are pathogenic and, upon binding to the receptor, trigger intracellular signal transduction. The autoantibodies are oligoclonal and as they are responsible for disease activity, their characterization would lead to a better understanding of the development of GD. Attempts to isolate anti-TSH-R antibodies from patients have proved to be difficult due to the exceedingly low serum levels due to rarity of these B cells, together with difficulties in obtaining purified TSH-R capable of interacting with patients autoantibodies. We employed phage antibody display technology and performed selection with a previously characterized semisynthetic antibody library on the purified extracellular ectodomain of the TSH-R. We report the isolation of six different anti-TSH-R monoclonal phage antibodies (moPhabs) from this library. All the moPhabs recognized TSH-R and its recombinant fragments by Western blotting, but failed to recognize the native TSH-R by flow cytometry. Consequently, the moPhabs did not lead to TSH-R activation. As these were the first moPhabs to TSH-R, they were analysed in terms of nucleotide and amino acid sequence and epitope specificity on the receptor. The moPhabs used immunoglobulin VH1 and VH3 germ line genes, all associated with Vλ3 genes. Interestingly, the CDR3 regions of all moPhabs were remarkably similar, though not identical. In light of the common CDR3 usage, the epitopes recognized on TSH-R appeared to be restricted to amino acids residues 405–411 and 357–364. In summary, our results show that semisynthetic libraries may be limited in isolating human monoclonal antibodies that resemble pathogenic antithyrotropin receptor autoantibodies present in patients with GD. It is likely that until preparations of purified TSH-R that can be recognized by patients autoantibodies become available, similar to the recently described

    An apparatus and a method for detecting a burial site of human remains are disclosed. An air stream is drawn through an air intake conduit from locations near potential burial sites of human remains. The air stream is monitored by one or more chemical sensors to determine whether the air stream includes one or more indicator compounds selected from halogenated compounds, hydrocarbons, nitrogen-containing compounds, sulfur-containing compounds, acid/ester compounds, oxygen-containing compounds, and naphthalene-containing compounds. When it is determined that an indicator compound is present in the air stream, this indicates that a burial site of human remains is below or nearby. Each sensor may be in electrical communication with an indicator that signals when the sensor has detected the presence of the indicator compound in the air stream. In one form, the indicator compound is a halogenated compound and/or a hydrocarbon, and the presence of the halogenated compound and/or the hydrocarbon in the air stream indicates that a burial site of human remains is below or nearby.

    This ongoing monitoring study provides forensic search teams with systematic geophysical data over simulated clandestine graves for comparison to active cases. Simulated "wrapped," "naked," and "control" burials were created. Multiple geophysical surveys were collected over 6 years, here showing data from 4 to 6 years after burial. Electrical resistivity (twin electrode and ERI), multifrequency GPR, grave and background soil water were collected. Resistivity surveys revealed that the naked burial had low-resistivity anomalies up to year four but then difficult to image, whereas the wrapped burial had consistent large high-resistivity anomalies. GPR 110- to 900-MHz frequency surveys showed that the wrapped burial could be detected throughout, but the naked burial was either not detectable or poorly resolved. 225-MHz frequency GPR data were optimal. Soil water analyses showed decreasing (years 4 to 5) to background (year 6) conductivity values. Results suggest both resistivity and GPR surveying if burial style unknown, with winter to spring surveys optimal and increasingly important as time increases. PMID:27404604

    A transient model for human Graves' disease was successfully established in mice using up to 3 immunizations with recombinant adenovirus expressing the extracellular A-subunit of the human TSH receptor (TSHR) (Ad-TSHR). We studied extension of adenovirally induced TSHR A-subunit immunization in mice by using a novel protocol of long-term 3- and 4-weekly injections. Generation of TSHR binding stimulatory antibodies (capacity to stimulate cAMP activity in TSHR-expressing test cells), goiter, and histological thyroid alterations were maintained for at least 9 months in all Ad-TSHR-immunized mice. In response to injection of 10(10) plaque-forming units of Ad-TSHR, also elevated mean serum T4 levels were observed throughout the study. Moreover, cardiac organ involvement (tachycardia and hypertrophy) were consistently observed in these mice. Higher doses of Ad-TSHR (10(11) plaque-forming units) did not produce consistent elevation of T4 and were not associated with a clear increase in heart rate vs controls, probably because these high doses provoked an immune response-induced tachycardia on their own. In summary, a long-term model of Graves' disease induced by a relatively simple protocol of continuing monthly immunizations should allow to investigate long-term disease mechanisms and may possibly obviate the need for more complicated disease models. Moreover, the clinical outcome predictor of tachycardia and cardiac involvement was reliably detected in the model. PMID:25562617

    Introduction. Pericardial effusion in the setting of hyperthyroidism is rare. We present a patient with Graves' disease who developed a sanguineous pericardial effusion and cardiac tamponade. Case Description. A 76-year-old man presenting with fatigue was diagnosed with Graves' disease and treated with methimazole. Two months later, he was hospitalized for uncontrolled atrial fibrillation. Electrocardiography showed diffuse low voltage and atrial fibrillation with rapid ventricular rate. Chest radiograph revealed an enlarged cardiac silhouette and left-sided pleural effusion. Thyroid stimulating hormone was undetectable, and free thyroxine was elevated. Diltiazem and heparin were started, and methimazole was increased. Transthoracic echocardiography revealed a large pericardial effusion with cardiac tamponade physiology. Pericardiocentesis obtained 1,050 mL of sanguineous fluid. The patient progressed to thyroid storm, treated with propylthiouracil, potassium iodine, hydrocortisone, and cholestyramine. Cultures and cytology of the pericardial fluid were negative. Thyroid hormone markers progressively normalized, and he improved clinically and was discharged. Discussion. We found 10 previously reported cases of pericardial effusions in the setting of hyperthyroidism. Heparin use may have contributed to the sanguineous nature of our patient's pericardial effusion, but other reported cases occurred without anticoagulation. Sanguineous and nonsanguineous pericardial effusions and cardiac tamponade may be due to hyperthyroidism. PMID:27446216

    Conflict and warfare are central but also disputed themes in discussions about the European Neolithic. Although a few recent population studies provide broad overviews, only a very limited number of currently known key sites provide precise insights into moments of extreme and mass violence and their impact on Neolithic societies. The massacre sites of Talheim, Germany, and Asparn/Schletz, Austria, have long been the focal points around which hypotheses concerning a final lethal crisis of the first Central European farmers of the Early Neolithic Linearbandkeramik Culture (LBK) have concentrated. With the recently examined LBK mass grave site of Schöneck-Kilianstädten, Germany, we present new conclusive and indisputable evidence for another massacre, adding new data to the discussion of LBK violence patterns. At least 26 individuals were violently killed by blunt force and arrow injuries before being deposited in a commingled mass grave. Although the absence and possible abduction of younger females has been suggested for other sites previously, a new violence-related pattern was identified here: the intentional and systematic breaking of lower limbs. The abundance of the identified perimortem fractures clearly indicates torture and/or mutilation of the victims. The new evidence presented here for unequivocal lethal violence on a large scale is put into perspective for the Early Neolithic of Central Europe and, in conjunction with previous results, indicates that massacres of entire communities were not isolated occurrences but rather were frequent features of the last phases of the LBK.

    In the present investigation some surface markers in peripheral blood T lymphocytes of patients with active Graves' disease and subjects in remission after /sup 131/I-therapy have been studied. We confirmed low TG levels in untreated patients and normal values in treated subjects. Increased percentages of DR+, MLR4+ (activated T cells), and 5/9+ (inducer-helper) T cells were detected in patients with active disease, thus indicating the presence of activated T cells and suggesting increased levels of helper T cells. High percentages of MLR4+ and 5/9+, but normal levels of DR+ were found in /sup 131/I-treated subjects. The different distribution of DR and MLR4 positivities on 5/9+ and 5+9-T cells confirm the different meaning of these two markers of the activation state. The imbalance of T-cell subsets found in /sup 131/I-treated subjects and the normal values observed in patients with hyperthyroidism due to toxic adenoma indicate that hyperthyroidism per se is not sufficient to explain the T-cell alterations. The possible meaning of these findings is discussed with respect to previous hypotheses on the pathogenesis of Graves' disease.

  15. Sanguineous Pericardial Effusion and Cardiac Tamponade in the Setting of Graves' Disease: Report of a Case and Review of Previously Reported Cases

    Introduction. Pericardial effusion in the setting of hyperthyroidism is rare. We present a patient with Graves' disease who developed a sanguineous pericardial effusion and cardiac tamponade. Case Description. A 76-year-old man presenting with fatigue was diagnosed with Graves' disease and treated with methimazole. Two months later, he was hospitalized for uncontrolled atrial fibrillation. Electrocardiography showed diffuse low voltage and atrial fibrillation with rapid ventricular rate. Chest radiograph revealed an enlarged cardiac silhouette and left-sided pleural effusion. Thyroid stimulating hormone was undetectable, and free thyroxine was elevated. Diltiazem and heparin were started, and methimazole was increased. Transthoracic echocardiography revealed a large pericardial effusion with cardiac tamponade physiology. Pericardiocentesis obtained 1,050 mL of sanguineous fluid. The patient progressed to thyroid storm, treated with propylthiouracil, potassium iodine, hydrocortisone, and cholestyramine. Cultures and cytology of the pericardial fluid were negative. Thyroid hormone markers progressively normalized, and he improved clinically and was discharged. Discussion. We found 10 previously reported cases of pericardial effusions in the setting of hyperthyroidism. Heparin use may have contributed to the sanguineous nature of our patient's pericardial effusion, but other reported cases occurred without anticoagulation. Sanguineous and nonsanguineous pericardial effusions and cardiac tamponade may be due to hyperthyroidism. PMID:27446216

    We report a 13-year-old girl with Graves disease, who showed an increased level of serum creatine kinase (CK) accompanied by myalgia after methimazole (MMI) treatment. This patient developed muscular pain two weeks after MMI administration, along with increased CK levels. The level of thyroid hormone was within the normal range when she showed increased CK levels. After the MMI dose was decreased and levo-thyroxine was added, serum CK levels decreased to normal and the myalgia improved. The pathophysiologic mechanism of this effect has not yet been elucidated. An acute relatively hypothyroid state occurs secondary to antithyroid drug (ATD) administration in chronic hyperthyroidism, which may cause changes in the CK levels. In this report, we present a rare pediatric case, along with a literature review of similar cases. In the initial state of MMI treatment, myalgia should be detected and when it occurs, CK levels should be measured. The clinical strategy of monitoring CK levels with the aim of normalizing thyroid hormones is helpful in case of the development of adverse reactions, such as myalgia, during ATD treatment for Graves disease in children.

    The detection of autoantibodies to the thyrotropin-receptor antibody (TRAb) is commonly used in clinical practice for the diagnostic assessment of Graves' disease (GD) and its differential diagnosis from toxic multinodular goiter (MNG) and autonomous adenoma. Additionally, TRAb assays can be useful during antithyroid drug treatment of GD to evaluate the risk of relapse and/or remission. The detection of TRAb was originally performed using a radioreceptor assay based on detergent-solubilized porcine thyroid membranes (TRAb). More recently new assays using purified porcine or recombinant human thyrotropin (TSH) receptor-coated plastic tubes (CT) have been developed (pCT-TRAb or hCT-TRAb). We have evaluated both assays (TRAb and pCTTRAb) in 300 individuals: healthy controls (n = 51); patients with GD before and after treatment (n = 200), patients with MNG (n = 29), and Hashimoto's thyroiditis [HT; n = 20]). All healthy controls and patients with HT had undetectable TRAb using both methods. Patients with active (not treated) GD had higher pCT-TRAb values (mean +/- standard deviation [SD], 58.2% +/- 20.3%, inhibition of TSH binding) compared to TRAb (41.2% +/- 15.4%, p < 0.01, Wilcoxon test). Results (as percent inhibition for both methods) had a positive and significant correlation (r = 0.68, p < 0.001). Moreover TRAb assay had a 97.3% sensitivity and 96.8% specificity; the pCT-TRAb sensitivity was 96.3% and specificity was 98.4% at a cutoff of 1.51 U/L. During treatment of GD, the TRAb method resulted in significantly lower (p < 0.05) values at 12, 24, and 30 months, while pCT-TRAb only exhibited significancy (compared to basal levels) at 30 months. The percent inhibition after 131I treatment of GD was significantly higher for pCT-TRAb (33.7 +/- 25.7) compared to TRAb (21.9 +/- 17.7, p < 0.01, Wilcoxon test). Only one patient with untreated MNG had a positive pCT-TRAb but negative TRAb value. Patients with MNG treated with 131I were divided into two groups: group 1

    Vascular and muscular involvements in Graves disease (GD) are rare. Here, we report a case of a 17-year-old patient with unilateral symptomatic middle cerebral artery stenosis concurrent with GD and myopathy. He presented with a 1-day history of acute severe right-sided hemiparesis and aphasia and a 3-week history of high metabolic syndrome. The pathogenesis of the stenosis is most likely vasculitis rather than atherosclerosis, based on contrast-enhanced high-resolution magnetic resonance imaging showing concentric wall enhancement. We suggest that lipid storage myopathy is secondary to GD, and it is likely mitochondrial dysfunction or immune dysfunction induced by GD responsible for the myopathy and that magnetic resonance spectroscopy (MRS) is capable of establishing the diagnosis of myopathy. Thus, MRS can be used for follow-up evaluations of the myopathy along with the pathology biopsy. PMID:25444029

    We asked 54 thyroidologists how they would treat each of four patients having moderate hyperthyroidism of Graves' disease and a thyroid gland weighing 70 g (three to four times normal). For a 19-year-old woman, 67% of thyroidologists recommended an initial course of therapy with antithyroid drugs, usually for 1 year; 24% favored radioiodine treatments; and 9%, surgery. Choices for treating a 19-year-old man were similar. For a 29-year-old man, 44% of thyroidologists preferred drug therapy; 50%, radioiodine; and 6%, surgery. For a 29-year-old woman, choices were similar to those for the 29-year-old man, except for a slight preference for drugs over radioiodine. If hyperthyroidism recurred after a first course of antithyroid drugs, the consultants favored radioiodine treatments and surgery about equally, except in the 29-year-old man, in whom radioiodine was preferred. This survey shows considerable variation among experts in treating hyperthyroidism in young adults.

    This study was designed to evaluate the effect of subtotal thyroidectomy and/or radioactive iodine therapy on plasma immunocalcitonin (iCT) levels and bone densities in patients treated for Graves' disease. Forty-eight women whose ages ranged from 29 to 79 years (mean, 55 years) were evaluated. All were at least 10 years beyond treatment. Fourteen patients had undergone subtotal thyroidectomy, 22 had received radioactive iodine therapy, and 12 had received both. Serum calcitonin levels were measured with the patient fasting and at 30 minutes and 2 hours after the ingestion of 15 mg of calcium in orange juice. Single photon absorptiometry was used to measure bone mineral density of the middle and distal radius. The mean fasting plasma levels of iCT for patients undergoing subtotal thyroidectomy was 27 +/- 2 mumol/L; women treated with radioactive iodine, 26 +/- 2; women undergoing subtotal thyroidectomy followed by radioactive iodine, 24 +/- 2, and for normal control women, 48.5 +/- 4.7. The mean stimulated iCT level of each of the patient groups was significantly lower than that of the normal controls (p = 0.01). There were no significant differences among the groups. Although there was an increased loss of bone mineral density in postmenopausal patients, with age and race as covariates, the bone densities of the distal radius in women undergoing subtotal thyroidectomy and/or receiving radioactive iodine were not significantly lower than those of normal control subjects (p greater than 0.05). These findings are consistent with other observations that patients treated by thyroidectomy and/or radioactive iodine for Graves' disease have lower basal levels of calcitonin and decreased calcitonin response to a provocative stimulus. Whether this loss of calcitonin reserve is a significant factor in development of postmenopausal osteoporosis remains unanswered.

    Patients with low thyroid peroxidase antibodies (anti-TPO) and increased TSH-receptor antibodies (TRAb) at diagnosis of Graves' disease (GD) have been suggested to have an increased risk to develop Graves' ophthalmopathy (GO). The aim was to evaluate if GO development can be predicted.This is an observational study with registration of possible GD and GO risk factors.399 patients with GD were registered 2003-2008 in Malmö, Sweden and out of these 310 were retrospectively followed up to 6 years. The main outcome measures were anti-TPO titer, TRAb titer, smoking habits, radioiodine treatment and GO development.TRAb was assessed with a third generation assay at GD diagnosis in 231 patients. The proportion of patients with GO increased above the median 6.3 IU/L both at diagnosis of GD (p=0.001) and at follow-up (p=0.0001).The distribution of GO patients anti-TPO above or below 20 kIU/L at diagnosis of GD was similar between groups (p=0.239). However at follow-up anti-TPO<20 kIU/L was associated with an increased proportion of newly developed GO as compared to the cohort with anti-TPO>20 kIU/L (p=0.018).87% of patients who developed GO after GD diagnosis had TRAb above 6.3 IU/L and/or anti-TPO below 20 kIU/L. The proportion of GO was doubled in GD patients treated with radioiodine but could not explain the described findingsAnti-TPO<20 kIU/L and/or TRAb>6.3 IE/L at the time of GD diagnosis were associated with an increased risk to develop GO after diagnosis of GD.

    The virtual experiments presented below reveal the counterintuitive archaeological demography of the Neolithic mass grave of Talheim and underline the importance of distinguishing between the demographic structures of living and dead populations, as well as between attritional and catastrophic mortality patterns. We utilise a new agent-based modelling approach called Population & Cemetery Simulator based on the NetLogo programming language and the Behaviour Composer of the modelling4all project, which allows us to extrapolate from dead to living populations and vice versa. Contrary to received opinion, we argue that the population of the Neolithic mass grave holds specific demographic information only, as it represents a pure catastrophic mortality pattern, i.e. a living population at a single point in time rather than the population of a conventional cemetery. The first experiments illustrate why the published demographic data (e.g. mortality, life expectancy, mean age at death) is misleading. It is illogical to utilise mortality tables devised for conventional (attritional) cemeteries in the case of living populations. Modelled populations with the published mortality rates of the massacre site are, furthermore, unable to stand up to plausible human demographic circumstances. In the second part, we evaluate the actual demographic information content of the Talheim sample. Comparative modelling illustrates that the Talheim population appears to be similar to possible living populations based on the mortuary record of Schwetzingen, an isochronal site of the Linear Pottery Culture (LBK), and Bärenthal, a site which dates back to the early medieval period (7th to 10th centuries). It is therefore very likely that the Talheim population is a representative sample of a living population in the LBK and might even represent a massacred village community in its entirety.

    As well as marine submersion or erosive phenomena, clay-silted sediment in-filling on estuarial and bay beaches are a main issue in these human-attractive areas. Coupled sandy/gravely and clay/silty intertidal areas can be observed in these particular coastal areas, depending of rivers characteristic (discharge of particle, water flow), ocean dynamics (wave exposure, current) and sediments sources. All around the world, sandy/gravely beaches are exposed to punctual or continuous input clay sediments. Vilaine estuary, Bay of Arcachon and Bay of Seine in France, Plymouth Bay in UK and also Wadden Sea in Deutschland are few examples of muddy/sandy coupled or mixed system. The beach of Bétahon (Ambon town, Brittany - France) is located on the external Vilaine estuary and is an example of this issue. This meso-macrotidal intermediate (low tide terrace) beach presents heterogeneous sediments. The upper intertidal zone is composed by sand and gravel and characterized by a steep slope. A very gentle slope characterized the lower part of the beach and is constituted by silt and clay. Clay/sand limit is characterized by a decimetric erosion cliff of mudflat along the beach. In order to understand bed variations and sediment transport of this complex heterogeneous beach, a well understanding of wave dynamic across the beach is necessary. This study focus on wave dynamics over the beach, using field observations and MIKE 21 3D wave numerical model. This paper is a preliminary approach of an upcoming global understanding of this estuarial beach behavior. Swell from deep-sea to near-shore area is modeled over a 100 km² area and real wind, deep sea wave characteristic, river water flow and tidal level are defined as open boundary conditions for the regional model. This last one is based on multiple bathymetric surveys over the last 50 years. Local model, triangular mesh gridded to 5 meters, covering Bétahon beach , is based on topographic and photographic survey of the mudflat

    The polymorphisms of thyroid stimulating hormone receptor (TSHR) intron 1 rs179247 and rs12101255 have been found to be associated with Graves' disease (GD) in genetic studies. In the present study, we conducted a meta-analysis to examine this association. Two reviewers systematically searched eligible studies in PubMed, Web of Science, Embase and China Biomedical Literature Database (CBM). A meta-analysis on the association between GD and TSHR intron 1 rs179247 or rs12101255 was performed. The odd ratios (OR) were estimated with 95% confidence interval (CI). Meta package in R was used for the analyses. Seven articles (13 studies) published between 2009 and 2014, involving 5754 GD patients and 5768 controls, were analyzed. The polymorphism of rs179247 was found to be associated with an increased GD risk in the allele analysis (A vs. G: OR=1.40, 95% CI=1.33-1.48) and all genetic models (AA vs. GG: OR=1.94, 95% CI=1.73-2.19; AA+AG vs. GG: OR=1.57, 95% CI=1.41-1.74; AA vs. AG+GG: OR=1.54, 95% CI=1.43-1.66). The site rs12101255 also conferred a risk of GD in the allele analysis (T vs. C: OR=1.50, 95% CI=1.40-1.60) and all genetic models (TT vs. CC: OR=2.22, 95% CI=1.92-2.57; TT+TC vs. CC: OR=1.66, 95% CI=1.50-1.83; TT vs. TC+CC: OR=1.74, 95% CI=1.53-1.98). Analysis of the relationship between rs179247 and Graves' ophthalmopathy (GO) showed no statistically significant correlation (A vs. G: OR=1.02, 95% CI=0.97-1.07). Publication bias was not significant. In conclusion, GD is associated with polymorphisms of TSHR intron 1 rs179247 and rs12101255. There is no association between rs179247 SNPs and GO. PMID:27465319

    Recently identified Fc receptor-like (FCRL) molecules are new members of the immunoglobulin superfamily dominantly expressed by B cells. Although FCRL expression patterns have been studied in normal and malignant cells, their biological functions and roles remain to be clearly identified in humans. Research has particularly focused on FCRL gene polymorphisms in autoimmune diseases, however, their involvement in the pathogenesis of autoimmune diseases is an interesting field for investigation. In the present study, we have investigated the gene expression profiles of FCRL1, 2, and 4 in 2 common thyroid diseases, Hashimoto's thyroiditis (HT) and Graves' disease (GD). FCRL1, 2, and 4 expressions were determined in peripheral blood samples of 55 HT patients, 40 GD patients and equal numbers of normal subjects by quantitative real-time PCR. Our results showed downregulation of FCRL1 and upregulation of FCRL2 transcripts in both HT and GD groups compared to healthy counterparts. Overexpression of FCRL4 was observed only in GD patients compared to controls. A significant correlation was observed between all FCRL gene expression levels in HT patients. Only FCRL2 and 4 had a correlation in GD patients. In addition, FCRL1, 2, and 4 gene expressions showed no correlations with the level of anti-thyroid peroxidase antibody (anti-TPO) or anti-thyroglobulin (anti-Tg) antibody from patients' sera. In conclusion, expressions of activating or inhibitory FCRL1, 2, and 4 showed significant alterations in HT and GD patients compared to healthy subjects. PMID:25738996

    Melting experiments of a synthesized, alkali-bearing, H-chondrite composition were conducted at ambient pressure with three distinct oxygen fugacity conditions (IW-1, IW, and IW+2). Oxygen fugacity conditions significantly influence the compositions of partial melts. Partial melts at IW-1 are distinctly enriched in SiO2 relative to those of IW and IW+2 melts. The silica-enriched, reduced (IW-1) melts are characterized by high alkali contents and have silica-oversaturated compositions. In contrast, the silica-depleted, oxidized (≥IW) melts, which are also enriched in alkali contents, have distinctly silica-undersaturated compositions. These experimental results suggest that alkali-rich, felsic, asteroidal crusts as represented by paired achondrites Graves Nunataks 06128 and 06129 should originate from a low-degree, relatively reduced partial melt from a parent body having near-chondritic compositions. Based on recent chronological constraints and numerical considerations as well as our experimental results, we propose that such felsic magmatism should have occurred in a parent body that is smaller in size and commenced accreting later than those highly differentiated asteroids having basaltic crusts and metallic cores.

    Graves' disease (GD) is an autoimmune thyroid disease defined by the production of stimulating autoantibodies to the thyroid-stimulating hormone receptor (TSHR) (TSAbs) that induce a sustained state of hyperthyroidism in patients. We previously demonstrated that TSHR, the target of this autoimmune response, is also a key susceptibility gene for GD, probably acting through thymic-dependent central tolerance. We also showed that TSHR is, unexpectedly, expressed in thymocytes. In this report, we confirm the expression of TSHR in thymocytes by protein immunoblotting and quantitative PCR, and show that expression is confined to maturing thymocytes. Using functional assays, we show that thymic TSHR is functional and that TSAbs can stimulate thymocytes through this receptor. This new activity of TSAbs on thymocytes may: 1) explain GD-associated thymic enlargement (hyperplasia), and 2) suggest the provocative hypothesis that the continuous stimulation of thymocytes by TSAbs could lead to a vicious cycle of iterative improvement of the affinity and stimulating capability of initially low-affinity antibacterial (e.g., Yersinia) Abs cross-reactive with TSHR, eventually leading to TSAbs. This may help to fill one of the gaps in our present understanding of unusual characteristics of TSAbs. PMID:25801430

    Purpose We aimed to investigate the predictive factors for early response to methimazole (MMI) in pediatric patients with Graves disease (GD). Methods Our study included 44 pediatric patients who were diagnosed with GD between January 1, 1993, and December 31, 2013, and were available for follow-up, achieving a normalization of thyroid functions (TFs) at the Chonbuk National University Hospital Pediatric Department. We retrospectively analyzed TFs such as tri-iodothyronine (T3), free thyroxine (fT4), thyroid-stimulating hormone (TSH), and thyroid antibody levels at diagnosis. We also examined their family history of thyroid disease, symptoms at presentation, and normalization time for TF after treatment. We divided our clinical series of patients into the following 4 age groups: <7 years old, 7–12 years old, 13–15 years old, and 16–18 years old. Results At diagnosis, the time of normalization of T3 was significantly shorter in the higher antimicrosomal antibody (AMA) group compared with the lower AMA group (2.53 months vs. 6.18 months) (P<0.05). However, the time of normalization of T3/fT4/TSH had no significant correlations with other variables such as age, sex, a family history of thyroid diseases, thyroglobulin, thyroid-stimulating immunoglobulin, or antithyroglobulin antibody (ATA). Conclusion Higher serological titers of AMA at diagnosis may have prognostic value in the response to initial MMI treatment in pediatric hyperthyroid GD patients. PMID:27462582

    We report a patient with branch retinal vein occlusion (BRVO) accompanied by superior ophthalmic vein (SOV) thrombosis resulting from severe SOV enlargement in a patient with Graves ophthalmopathy (GO). A 78-year-old woman diagnosed with BRVO presented with reduced vision. She had a more than 20-year history of unilateral GO. Fluorescein angiography and spectralis optical coherence tomography revealed BRVO with cystoid macular edema. Approximately 5 months later, she complained of advanced left proptosis. A computed tomography scan at that time revealed dilated SOV with high internal attenuation due to SOV thrombosis of the left orbit. Because of the uncertain onset of SOV thrombosis and minimal signs of acute orbital congestion, we prescribed prophylactic daily aspirin to improve blood flow rather than a heparin-based treatment. In addition, she was treated with lubricants for exposure keratopathy and a dorzolamide/timolol eyedrops to prevent increases in intraocular pressure. This is the first clinical report of BRVO accompanied by SOV thrombosis due to SOV enlargement in chronic severe GO. It should be recognized that SOV thrombosis can lead to an increase in proptosis even in chronic GO. PMID:24978681

    A recent association scan using a genome-wide set of nonsynonymous coding single-nucleotide polymorphisms (nsSNPs) conducted in four diseases including Graves' disease (GD), identified nine novel possible regions of association with GD. We used a case–control approach in an attempt to replicate association of these nine regions in an independent collection of 1578 British GD patients and 1946 matched Caucasian controls. Although none of these loci showed evidence of association with GD in the independent data set, when combined with the original Wellcome Trust Case–Control Consortium study group, minor differences in allele frequencies (P⩾10−3) remained in the combined collection of 5924 subjects for four of the nsSNPs, present within HDLBP, TEKT1, JSRP1 and UTX. An additional 29 Tag SNPs were screened within these four gene regions to determine if further associations could be detected. Similarly, minor differences only (P=0.042–0.002) were detected in two HDLBP and two TEKT1 Tag SNPs in the combined UK GD collection. In conclusion, it is unlikely that the SNPs selected in this replication study have a significant effect on the risk of GD in the United Kingdom. Our study confirms the need for large data sets and stringent analysis criteria when searching for susceptibility loci in common diseases. PMID:20442750

    We have prepared a biotinylated thyrotropin receptor (TSHR-BIO), and characterized its activity in cells and when bound to solid phase (streptavidin agarose). TSHR-BIO consists of the N-terminal 725 amino acids of the human thyrotropin (TSH) receptor linked to the 87-amino acid C-terminal domain of the biotin carboxyl carrier protein subunit of Escherichia coli acetyl-CoA carboxylase. The C-terminal domain directs the efficient post-translational biotinylation of the protein. TSHR-BIO was expressed using a vaccinia virus expression system. HeLa cells infected with recombinant virus produced large amounts of TSH receptor of approximately 120,000 molecules per cell. Vaccinia virus produced TSHR-BIO was fully functional interacting with TSH (Kd of 2.3+/-0.1 x 10(-10) M) and coupling to cyclic adenosine monophosphate (cAMP) second messenger system. The expressed protein was biotinylated with high efficiency; more than 90% of TSHR-BIO was bound to streptavidin. We have shown the application of streptavidin agarose immobilized TSHR-BIO for the detection of thyroid-binding inhibiting immunoglobulines in unfractionated sera. There was a good positive correlation between the results obtained in this assay and the commercially available TRAK assay performed with solubilized porcine TSH receptor (r = 0.71; p < 0.001, in 45 sera of patients with Graves' disease and 17 normal sera).

    There are doubtful points about the theory that autoimmunity with auto-antibody (Ab) to TSH receptor (R) causes hyperthyroidism in Graves' disease (GD). A main doubtful point is no curative effect of corticosteroid on Graves' hyperthyroidism in spite of curative effect of corticosteroid for all autoimmune diseases. Recently we demonstrated the immunological similarity of TSAb and TBAb-IgG to animal IgGs, except for human (h)IgG, by neutralization and purification of TSAb and TBAb-IgG using (1) heterophilic Ab to animal IgG in GD sera and (2) experimentally generated anti-animal IgG Abs [such as dog (d), bovine (b), porcine (p), and rabbit (rb)]. Furthermore, greater immunological similarity of Fab- and F(ab')(2)-portion of TSAb- and TBAb-IgG to bovine Fab, compared to hFab, was demonstrated using goat anti-bovine F(ab')(2) Ab. Existence of b and p TSH-like portions in the LATS-IgG molecule (probably Fab portion) was suggested by a previous report of neutralization of LATS activity by anti-b- or anti-p-TSH Ab. We suggested the existence of a mammalian animal-TSH-like structure, excepting hTSH, in the TSAb-IgG molecule (probably Fab portion), by discovery of anti-mammalian TSH Ab (such as d, b, p, guinea-pig, rat, whale, except h) in sera of GD. Lately, similar TSHR binding of H- and L-chain of human stimulating monoclonal TSHR Ab (M22)-Fab with TSH-α and-β subunit was reported. This evidence suggests that Fab portion of TSAb has a structure like mammalian TSH, but not hTSH. IgG-λ type of d, horse, b, p, goat, ovine is 95% and IgG-κ type is 5%, while human κ and λ chain is 60:40. Previous report that LATS (TSAb)-IgG composed of predominant λ type is supporting evidence that TRAb-IgG has immunological similarity with these animal IgGs compared to hIgG. We speculate that TSAb-IgG may be referred as a mermaid consisted in face (Fab) and trunk-leg (Fc). Face may be a kind of hormone with animal TSH-like structure and trunk-leg has animal IgG-like structure (in

    One of the major challenges to the more widespread use of individualized, dosimetry-based radioiodine treatment of Graves' disease is the development of a reasonably fast, simple, and cost-effective method to measure thyroidal {sup 131}I kinetics in patients. Even though the fixed activity administration method does not optimize the therapy, giving often too high or too low a dose to the gland, it provides effective treatment for almost 80% of patients without consuming excessive time and resources. In this article two simple methods for the evaluation of the kinetics of {sup 131}I in the thyroid gland are presented and discussed. The first is based on two measurements 4 and 24 h after a diagnostic {sup 131}I administration and the second on one measurement 4 h after such an administration and a linear correlation between this measurement and the maximum uptake in the thyroid. The thyroid absorbed dose calculated by each of the two methods is compared to that calculated by a more complete {sup 131}I kinetics evaluation, based on seven thyroid uptake measurements for 35 patients at various times after the therapy administration. There are differences in the thyroid absorbed doses between those derived by each of the two simpler methods and the ''reference'' value (derived by more complete uptake measurements following the therapeutic {sup 131}I administration), with 20% median and 40% 90-percentile differences for the first method (i.e., based on two thyroid uptake measurements at 4 and 24 h after {sup 131}I administration) and 25% median and 45% 90-percentile differences for the second method (i.e., based on one measurement at 4 h post-administration). Predictably, although relatively fast and convenient, neither of these simpler methods appears to be as accurate as thyroid dose estimates based on more complete kinetic data.

  14. Opaque assemblages in CR2 Graves Nunataks (GRA) 06100 as indicators of shock-driven hydrothermal alteration in the CR chondrite parent body

    We have studied the petrologic characteristics of sulfide-metal lodes, polymineralic Fe-Ni nodules, and opaque assemblages in the CR2 chondrite Graves Nunataks (GRA) 06100, one of the most altered CR chondrites. Unlike low petrologic type CR chondrites, alteration of metal appears to have played a central role in the formation of secondary minerals in GRA 06100. Differences in the mineralogy and chemical compositions of materials in GRA 06100 suggest that it experienced higher temperatures than other CR2 chondrites. Mineralogic features indicative of high temperature include: (1) exsolution of Ni-poor and Ni-rich metal from nebular kamacite; (2) formation of sulfides, oxides, and phosphates; (3) changes in the Co/Ni ratios; and (4) carbidization of Fe-Ni metal. The conspicuous absence of pentlandite may indicate that peak temperatures exceeded 600 °C. Opaques appear to have been affected by the action of aqueous fluids that resulted in the formation of abundant oxides, Fe-rich carbonates, including endmember ankerite, and the sulfide-silicate-phosphate scorzalite. We suggest that these materials formed via impact-driven metamorphism. Mineralogic features indicative of impact metamorphism include (1) the presence of sulfide-metal lodes; (2) the abundance of polymineralic opaque assemblages with mosaic-like textures; and (3) the presence of suessite. Initial shock metamorphism probably resulted in replacement of nebular Fe-Ni metal in chondrules and in matrix by Ni-rich, Co-rich Fe metal, Al-Ti-Cr-rich alloys, and Fe sulfides, while subsequent hydrothermal alteration produced accessory oxides, phosphates, and Fe carbonates. An extensive network of sulfide-metal veins permitted effective exchange of siderophile elements from pre-existing metal nodules with adjacent chondrules and matrix, resulting in unusually high Fe contents in these objects.

    Abstract A choice of the optimal treatment for Graves ophthalmopathy (GO) is a challenge due to the complexity of the pathogenesis. Alpha-lipoic acid (ALA) is well known as a multifunctional antioxidant, helping to protect cells against oxidative stress and inflammatory damage. The aim of this study was to investigate the effects of ALA on intracellular production of reactive oxygen species (ROS), inflammation, and adipogenesis using primary cultured orbital fibroblasts from patients with GO. Intracellular ROS levels and mRNA expressions of proinflammatory cytokines and chemokines including intercellular adhesion molecule-1 (ICAM-1), interleukin (IL)-6, monocyte chemoattractant protein (MCP)-1, and regulated upon activation normal T cell expressed and presumably secreted (RANTES) were measured. After adipogenesis, the expressions of peroxisome proliferator-activated receptor (PPAR)γ, CCAAT-enhancer-binding proteins (C/EBP)α and β, and heme oxygenase-1 (HO-1) were investigated. H2O2 dose-dependently stimulated ROS production and HO-1 expression. Addition of ALA strongly attenuated ROS production and further increased HO-1 expression. However, by pretreatment of zinc protoporphyrin (ZnPP), HO-1 inhibitor, ALA inhibition of ROS generation by H2O2 was abolished. Tumor necrosis factor (TNF)α-induced mRNA expressions of ICAM-1, IL-6, MCP-1, and RANTES were inhibited by ALA treatment. In this context, TNFα-induced phosphorylation of P65 was also inhibited. In addition, ALA dose-dependently inhibited H2O2-induced intracellular accumulation of lipid droplets. The expression of adipogenic transcription factors, including PPARγ, C/EBPα, and β, was also inhibited. ALA is a potential therapeutic agent for GO because of the inhibitory effects on ROS production and gene expression of proinflammatory cytokines and chemokines, resulting in prevention of adipose-tissue expansion.

    Until now, no data are present about the effect of peroxisome proliferator-activated receptor (PPAR){alpha} activation on the prototype Th1 [chemokine (C-X-C motif) ligand (CXCL)10] (CXCL10) and Th2 [chemokine (C-C motif) ligand 2] (CCL2) chemokines secretion in thyroid cells. The role of PPAR{alpha} and PPAR{gamma} activation on CXCL10 and CCL2 secretion was tested in Graves' disease (GD) and control primary thyrocytes stimulated with interferon (IFN){gamma} and tumor necrosis factor (TNF){alpha}. IFN{gamma} stimulated both CXCL10 and CCL2 secretion in primary GD and control thyrocytes. TNF{alpha} alone stimulated CCL2 secretion, while had no effect on CXCL10. The combination of IFN{gamma} and TNF{alpha} had a synergistic effect both on CXCL10 and CCL2 chemokines in GD thyrocytes at levels comparable to those of controls. PPAR{alpha} activators inhibited the secretion of both chemokines (stimulated with IFN{gamma} and TNF{alpha}) at a level higher (for CXCL10, about 60-72%) than PPAR{gamma} agonists (about 25-35%), which were confirmed to inhibit CXCL10, but not CCL2. Our data show that CCL2 is modulated by IFN{gamma} and TNF{alpha} in GD and normal thyrocytes. Furthermore we first show that PPAR{alpha} activators inhibit the secretion of CXCL10 and CCL2 in thyrocytes, suggesting that PPAR{alpha} may be involved in the modulation of the immune response in the thyroid.

    We recently described a preclinical model of Graves' orbitopathy (GO), induced by genetic immunization of eukaryotic expression plasmid encoding human TSH receptor (TSHR) A-subunit by muscle electroporation in female BALB/c mice. The onset of orbital pathology is characterized by muscle inflammation, adipogenesis, and fibrosis. Animal models of autoimmunity are influenced by their environmental exposures. This follow-up study was undertaken to investigate the development of experimental GO in 2 different locations, run in parallel under comparable housing conditions. Functional antibodies to TSHR were induced in TSHR A-subunit plasmid-immunized animals, and antibodies to IGF-1 receptor α-subunit were also present, whereas control animals were negative in both locations. Splenic T cells from TSHR A-subunit primed animals undergoing GO in both locations showed proliferative responses to purified TSHR antigen and secreted interferon-γ, IL-10, IL-6, and TNF-α cytokines. Histopathological evaluation showed orbital tissue damage in mice undergoing GO, manifest by adipogenesis, fibrosis, and muscle damage with classic signs of myopathy. Although no inflammatory infiltrate was observed in orbital tissue in either location, the appearances were consistent with a "hit-and-run" immune-mediated inflammatory event. A statistically significant increase of cumulative incidence of orbital pathology when compared with control animals was shown for both locations, confirming onset of orbital dysimmune myopathy. Our findings confirm expansion of the model in different environments, accompanied with increased prevalence of T cell-derived proinflammatory cytokines, with relevance for pathogenesis. Wider availability of the model makes it suitable for mechanistic studies into pathogenesis and undertaking of novel therapeutic approaches. PMID:26872090

    There are scarce reports regarding a functional prognostic value of thyroid-stimulating autoantibody (TSAb) levels using a thyroid-stimulating hormone receptor chimera (Mc4) in Graves' disease (GD) in iodine sufficient area. The aim of this study was to investigate whether Mc4-TSAb can predict GD remission/relapse after antithyroid drug (ATD) treatment and to compare Mc4-TSAb with a binding assay using M22 monoclonal antibody (M22-TRAb) in GD patients. We retrospectively reviewed the results of M22-TRAb and Mc4-TSAb in GD patients treated with ATD for 12 months. GD patients who underwent ATD treatment for at least 12 months were included. We compared the predictive values of M22-TRAb and Mc4-TSAb for GD remission and relapse. Of the 92 patients, 60 (65.2%) achieved remission and 32 (34.8%) relapsed within 12 months. In receiver operating characteristic analysis, there were no significant differences in the area under the curves (AUCs) between Mc4-TSAb [AUC=0.79 (95% CI 0.69-0.89)] and M22-TRAb [AUC=0.69 (95% CI 0.58-0.81)]. The optimal predictive cut-off values of M22-TRAb and Mc4-TSAb were 2.23 IU/L and 230%, respectively. At a high Mc4-TSAb cut-off, the better specificity of 85.0% and positive predictive value (PPV) of 69.0% were shown compared with those at the best cut-off for M22-TRAb. In conclusion, a high cut-off for an Mc4 assay may improve the predictive value of relapse with superior specificity and PPV compared with M22-TRAb in treated GD. PMID:24968734

    Graves disease (GB) is an autoimmune disease of the thyroid gland. Genes of, or closely associated to, the HLA complex are assumed to contribute to the genetic predisposition to GD. The authors have previously reported an increased frequency of HLA-DR3/DQ3 in Caucasian patients with GD, and recently the importance of Dw24 encoded by DRB3 gene has been suggested. To further investigate the associations of GD and these genes, 94 unrelated patients with GD and 75 control subjects were typed for HLA-DRB3, -DRB1, and -DQA1, and -DQB1, using sequence-specific oligonucleotide probes to analyze polymerase chain reaction amplified DNA (PCR-SSO). Three findings emerged from these studies. (1) The frequency of subjects positive for DQA1*0501 (GD, 73.4% vs. control 42.7%, P = 0.0001, RR = 3.71) was significantly increased among patients. The frequency of DR3 (GD, 34.0% vs. control 17.3%, P = 0.0146, RR = 2.46), which is in tight linkage disequilibrium with DQA1*0501, was also increased; however, it was not significant when the P value was corrected for the number of antigens tested. Neither DQB1 nor DRB3 alleles were significantly increased in frequency. (2) After exclusion of DR3-positive subjects, DQA1*0501 was still significantly increased (GD, 59.7% vs. control 30.6%, P = 0.0012, Pc < 0.01, RR = 3.35) among patients. (3) The distributions of Dw24 and Dw25,26 (Dw25 or Dw26) did not differ between patients and controls on either DR3 positive or negative groups. These findings suggest the DQA1*0501, or a closely associated unknown gene, confers susceptibility to GD, while Dw24 is not directly involved. The importance of DR3, however, remains to be elucidated, because of the fixed linkage with DQA1*0501. 34 refs., 1 fig., 5 tabs.

    Association of the major histocompatibility complex (MHC) class II-encoded HLA-DRB1-DQA1-DQB1 haplotype with Graves' disease (GD) has been known for several years. Recent evidence from other autoimmune diseases has suggested that the HLA class I encoded HLA-B/-C molecules could be conferring HLA-DRB1-DQA1-DQB1 independent effects on disease. The aim of this study was to determine the effect of HLA-B and HLA-C in GD in a white ethnic group of 806 patients with GD and 487 control subjects from the UK. Of the five loci (HLA-B, -C, -DRB1, -DQA1, -DQB1), HLA-C demonstrated the strongest association (P = 1.20 x 10(-20)) with HLA-C*07 predisposing [OR = 1.63, 95% CI (1.23-2.17)] and both HLA-C*03 [OR = 0.54, 95% CI (0.38-0.77)], HLA-C*16 [OR = 0.36, 95% CI (0.21-0.61)] protective. The other loci were then tested for HLA-C-independent associations. HLA-B was found to be associated independently of HLA-C (P = 1.54 x 10(-6)) with the other three loci, HLA-DRB1, HLA-DQB1 and HLA-DQA1, also improving the model but with less confidence (P > 10(-5)). This study has for the first time provided evidence of a primary association of HLA-C, and to a lesser extent HLA-B, with GD. Class II loci could still have effects on GD, but they appear smaller than the HLA-C association. A full investigation of the MHC region, including all class I and II loci is now required. Our results point to a primary role for class I-mediated responses in GD, a condition classically assumed to be a straightforward HLA-class II-restricted autoantibody response to the thyroid stimulating hormone receptor.

    Background: Thionamide antithyroid drugs (ATDs) have certain disadvantages and are associated with some adverse events (AEs). To overcome the problems associated with ATDs, a compound antithyroid ointment (CATO) containing methimazole (MMI) and hydrocortisone has been developed for use as a local thyroid treatment (LTT). Objective: The aim of this study was to assess the clinical effectiveness and tolerability of CATO LTT in patients with Graves disease (GD). Methods: This was a prospective, randomized, open-label, parallel-group clinical trial conducted at the Provincial Hospital Affiliated to Shandong University (Jinan, China). Patients with GD aged 19 to 65 years were randomized to receive either CATO LTT 0.3 g/d or oral MMI 37.5 mg/d (control group) treatment for 18 months, with a 4-year follow-up period. Hyperthyroid symptoms, thyroid function, granulocyte count, liver function, and AEs were assessed at baseline and every 2 weeks until serum thyroid hormone (TH) concentration normalized, at which point patients were assessed monthly. The primary efficacy end points were the duration of treatment required for serum TH concentration to normalize and the remission rate after completing the 18-month treatment regimen. Results: A total of 154 patients (133 women, 21 men; mean [SD] age, 39.6 [11.8] years; all Han Chinese) participated in the study; all patients completed the 18-month treatment period. Compared with the MMI group (n 76), the CATO- treated group (n 78) had a significantly shorter median (range) time to restoration of normal serum thyroid hormone concentration (43 [12–150] vs 22 [7–60] days; P < 0.001), a significantly lower rate of recurrence of hyperthyroidism (309/1520 [20.3%] vs 193/1368 [14.1%] person-time; P < 0.001), a significantly lower drug hypothyroidism rate (185/1520 [12.2%] vs 54/1368 [3.9%] person-time; P < 0.001), and a higher remission rate (year 1:46/69 [66.7%] vs 65/72 [90.3%] patients, P 0.001; year 2:40/69 [58.0%] vs 60/72 [83

    Activation of certain adhesion molecules within vascular endothelium and the surrounding extravascular space is a critical event in the recruitment and targeting of an inflammatory response or autoimmune attack to a particular tissue site. We have recently demonstrated that the adhesion of lymphocytes to cultured retroocular fibroblasts obtained from patients with Graves' ophthalmopathy (GO) is mediated predominantly by the interaction of lymphocyte function-associated antigen-1 (LFA-1), expressed on lymphocytes, with intercellular adhesion molecule-1 (ICAM-1), expressed by these cells following exposure to interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha), IL-1 alpha or purified thyroid-stimulating immunoglobulins. We now report the expression and localization in situ of several adhesion molecules, ICAM-1, endothelial leucocyte adhesion molecule-1 (ELAM-1), vascular cell adhesion molecule-1 (VCAM-1), and LFA-3 in retroocular tissues derived from patients with severe GO (n = 4) and normal individuals (n = 3). Serial cryostat sections of tissue specimens were processed for immunoperoxidase staining using various MoAbs against ICAM-1, ELAM-1, VCAM-1 and LFA-3. In addition, consecutive sections were stained with MoAbs against LFA-1, CD45RO (UCHL-1)DR-human leucocyte antigen (HLA-DR), CD11b/CD18 (Mac-1), and CD11c/CD18 (p150,95). In GO-retroocular tissues, strong immunoreactivity for ICAM-1 and LFA-3 was detected in blood vessels (> 90%), in perimysial fibroblasts surrounding extraocular muscle fibres, and in connective tissue distinct from extraocular muscle. No ICAM-1 or LFA-3 immunoreactivity was present in extraocular muscle cells themselves. ICAM-1 and LFA-3 immunoreactivity in normal tissues was minimal or absent both in connective and muscle tissues. Vascular endothelium was strongly positive for ELAM-1 and VCAM-1 in GO-retroocular tissues, while VCAM-1 immunoreactivity was minimal (< 5% of blood vessels) and ELAM-1 immunoreactivity was

    New major- and trace-element abundances, highly siderophile element (HSE: Os, Ir, Ru, Pt, Pd, Re) abundances, and oxygen and rhenium-osmium isotope data are reported for oligoclase-rich meteorites Graves Nunataks 06128 and 06129 (GRA 06128/9), six brachinites (Brachina; Elephant Morraine 99402/7; Northwest Africa (NWA) 1500; NWA 3151; NWA 4872; NWA 4882) and three olivine-rich achondrites, which are referred to here as brachinite-like achondrites (NWA 5400; NWA 6077; Zag (b)). GRA 06128/9 represent examples of felsic and highly-sodic melt products from an asteroid that may provide a differentiation complement to brachinites and/or brachinite-like achondrites. The new data, together with our petrological observations, are consistent with derivation of GRA 06128/9, brachinites and the three brachinite-like achondrites from nominally volatile-rich and oxidised 'chondritic' precursor sources within their respective parent bodies. Furthermore, the range of Δ17O values (˜0‰ to -0.3‰) among the meteorites indicates generation from isotopically heterogeneous sources that never completely melted, or isotopically homogenised. It is possible to generate major- and trace-element compositions similar to brachinites and the three studied brachinite-like achondrites as residues of moderate degrees (13-30%) of partial melting of primitive chondritic sources. This process was coupled with inefficient removal of silica-saturated, high Fe/Mg felsic melts with compositions similar to GRA 06128/9. Melting of the parent bodies of GRA 06128/9, brachinites and brachinite-like achondrites halted well before extensive differentiation, possibly due to the exhaustion of the short-lived radionuclide 26Al by felsic melt segregation. This mechanism provides a potential explanation for the cessation of run-away melting in asteroids to preserve achondrites such as GRA 06128/9, brachinites, brachinite-like achondrites, acapulcoite-lodranites, ureilites and aubrites. Moderate degrees of

La répartition annuelle des patientes ainsi que les caractéristiques démographiques et obstétricales étaient comparables dans leur globalité sur les quatre années. Les pratiques thérapeutiques étaient également comparables. Le taux global de mortalité par hémorragie dans notre unité était à 4,7%, avec un taux annuel de mortalité stable. L'analyse des facteurs de risque de mortalité par hémorragie en milieu de réanimation a montré une association statistiquement significative entre la survenue du décès et les facteurs suivants: recours aux catécholamines, survenue de sepsis, œdème pulmonaire aigu, coagulation intravasculaire disséminée, insuffisance rénale aigue avec recours à l'hémodialyse, SDRA ou TRALI, atteinte neurologique grave, défaillance multiviscérale et arrêt cardiaque récupéré.

    Cysteine 390 of the rat thyrotropin (TSH) receptor, when mutated to serine, results in a receptor with a reduced ability of TSH to bind and increase cAMP levels but a preserved ability of thyroid stimulating autoantibodies (TSAbs) from hyperthyroid Graves' patients to increase cAMP levels. The ability of receptor autoantibodies from hypothyroid patients with idiopathic myxedema to inhibit the TSAb activity which is preserved is, however, like TSH binding, significantly reduced. Cysteine 390, together with tyrosine 385, thus appears to be an important determinant in a high affinity TSH binding site which is an epitope for receptor autoantibodies which block TSH or TSAb action and cause hypothyroidism rather than TSAbs which increase cAMP levels and are associated with hyperthyroidism. Threonine 388 and aspartic acid 403 may contribute to this ligand interaction site. PMID:1719963

    Les pyréthrinoïdes sont des insecticides largement utilisés du fait de leur efficacité et de leur relative sécurité chez l'homme. Les intoxications mortelles liées à ces agents restent exceptionnelles. Leur métabolisme hépatique rapide limite considérablement leur toxicité chez l'homme. Cette observation relate une intoxication grave à un pyréthrinoïde (la cyperméthrine) dont le solvant était l'éthylène glycol. Ce dernier est un toxique nettement plus dangereux pour l'homme. Le tableau clinique consistait en une atteinte multiviscérale avec prédominance de la défaillance cardiovasculaire et neurologique. Le faible potentiel toxique des pyréthrinoïdes suggère l'implication évidente de l'éthylène glycol dans la gravité de cette intoxication. La prise en charge thérapeutique, essentiellement symptomatique, n'a pas pris en compte la présence d'éthylène glycol dans la formulation de l'insecticide. L'évolution clinique était défavorable. Devant toute intoxication grave à un insecticide pyréthrinoïde une intoxication associée au solvant tel que l'éthylène glycol doit être recherchée et traitée. PMID:23734273

    Introduction Les accidents domestiques de l'enfant représentent un vrai problème de santé publique dans les pays industrialisés. Au Maroc, la priorité en santé publique est toujours donnée aux pathologies infectieuses, et bien qu'elle soit très peu décrite, la pathologie accidentelle de l'enfant devient de plus en plus fréquente dans notre pays avec une mortalité importante. L'objectif est de mettre le point sur la prévalence, la gravité, les aspects étiologiques, les facteurs de risque et les circonstances de survenue de ces accidents, ainsi que les moyens de prévention active et passive. Méthodes Enquête rétrospective descriptive sur une période de douze mois portant sur tous les enfants pris en charge pour accident domestique grave au service de réanimation pédiatrique polyvalente de l'hôpital universitaire d'enfants de Rabat. Résultats Parmi 698 admissions, 108 cas d'accidents domestiques graves ont étaient colligés (soit 15,5%), L’âge moyen des enfants était de 04ans tout accident confondu, avec un sex-ratio de 1,08 en faveur des garçons. L’évolution générale était marquée par le décès de 16 enfants (soit 14,8%) parmi 164 décès toute pathologie confondue au cours de la même période d’étude (soit 9,75% des décès) avec une durée moyenne d'hospitalisation de 04jours. les brûlures constituaient le premier accident dans notre série par 37cas, et elles étaient la première cause de mortalité par huit cas; par ailleurs, la population la plus à risque de brûlure était les nourrissons (67,6%). L'inhalation intrabronchique d’épingle à foulard (accident particulier dans notre contexte islamique) à été retrouvée chez six cas. Conclusion Les accidents domestiques de l'enfant constituent rarement une préoccupation de premier plan dans la population alors qu'ils sont parfois très graves et source d'une mortalité importante. Le meilleur traitement reste la prévention active et passive. PMID:26015848

    Graves' disease (GD) is the only autoimmune disease where autoantibodies stimulate the target organs. Among the most common clinical manifestations are hyperthyroidism and orbitopathy (GO). To ensure the diagnosis of autoimmune hyperthyroidism, activity of TSH receptor autoantibodies (TRAb) should be determined. Because of their significantly improved sensitivity and equal specificity, second-generation TRAb assays (activity given in IU/l) should be preferred over first-generation assays (activity given in U/l). During follow-up of antithyroid drug therapy it is possible to predict outcome for some patients with high chances if TRAb levels are high. On this basis, thyreoablative treatment (operation or radioiodine) can already be indicated before the 1st year of antithyroid drug treatment has passed. If TRAb antibody titers are > 10 IU/l, it is possible to predict outcome as early as 6 months after initiation of antithyroid drug therapy. Below a certain threshold, depending on the time point of measurement, no representative risk analyses are available for TRAbs. TRAb measurement is also helpful to determine the course of GO. This may guide the physician through crucial treatment decisions, especially if the patient is at risk of deterioration. PMID:19444414

    Although literature has offered methods to predict 24-hour radioactive iodine uptake values from early (4- to 6-hour) measurements, the resultant dosage errors have not been examined. Potential errors include underdosage, overdosage, and a failure to recognize rapid turnover patients (early-to-late uptake ratios > or = 1) who are at high risk for treatment failure and full-body radiation exposure. We developed and tested a novel method for minimizing error involved in using a single early uptake measurement to derive late uptake. From a retrospective analysis of 203 Graves' disease patients, receiver operating characteristic (ROC) curve analysis enabled us to identify patients likely to experience rapid turnover and therefore should receive 24-hour studies. Twenty-four-hour uptake measurements are necessary with 77% or more 4-hour uptake values and 80% or more 6-hour values. After eliminating these patients, we developed linear regression equations to predict the 24-hour uptake from 4-hour (n = 61) and 6-hour (n = 22) rule groups, testing their efficacy on separate 4-hour (n = 61) and 6-hour (n = 21) patient groups. We also used our test population to measure error in four early-to-late uptake conversion formulas presented in the literature. Error involved in these predictions ranged from a 10.6% overestimate for 4-hour calculations to a 5.9% underestimate for 6-hour calculations. When applied to two dosage formulas incorporating gland size, absorbed dose, and 24-hour uptake, average dosage error was 7%. In comparison to the other sources of error radioactive iodine (131I) dosimetry, potential error in predicting 24-hour uptake from 4- or 6-hour uptake values is low. PMID:11041455

    Thyroid-associated ophthalmopathy is a disease caused by autoimmune processes that also affects the thyroid gland and the lower limbs; at orbital level, it involves the muscle and adipose tissue. When medical treatment fails to achieve appreciable results, surgery aims to decompress the orbital cavity. In recent years, the treatment has been considerably improved by the introduction of transpalpebral lipectomy, which has produced valid results especially in cases when extrinsic muscle hypertrophy is limited; if it is severe, however, lipectomy can be combined with expansion of the orbital cavity, thus enabling the latter to be restricted to one or two walls instead of three. Studying 52 patients who underwent orbital decompression involving lipectomy and/or orbital expansion, affecting a total of 96 orbits, enabled an assessment of the pros and cons of the single techniques in an attempt to identify a rational approach to this pathology. It emerged that lipectomy alone may suffice and obtain valid results in cases of mild-to-moderate proptosis (up to 24 mm) with limited extrinsic muscle hypertrophy, whereas orbital expansion--with or without lipectomy--is likely to be necessary in moderate-to-severe cases (proptosis greater than 24 mm). Additional procedures to correct the elevator and retractor muscles of the eyelids were almost always necessary. PMID:15605519

    The article is based on a paper read as a invited speaker at a conference, entitled "Medical experts and expertise in cases of humanitarian crises "convened by the University of Geneva and the Committee of the International Red Cross in April 2007. The article starts with an overview of Polish history from the end of World War I up to the disclosure of the mass graves in the spring of 1943, but is otherwise a translation of the original English lecture with some additions from new findings.in archives. Helge tramsen was born into a bourgois family in Copenhagen. After graduation in medicine from the University of Copenhegen in 1936 he married a British woman and joined the naval medical corps and also embarked on a surgical career.. From 1940 to 1943 he was prosector at the Institute of Forensic Medicine at the University of Copenhagen. After the finding of the mass graves at Katyn, Germany requested from a number of European countries under German control forensic experts to join an international commission to investigate the findings. As the professor of forensic medicine declined perobably due to health reasons Tramsen was sent. During the German occupation of Denmark 1940 to 1945 Tramsen according to family tradition participated in the resistance movement and he consulted with members of the more conservative part of it and was recommended to go to Germany with an added purpose of being able to transport material out of Germany. He went with special plane from Copenhagen to Berlin, where he joined the international group, which later flew to Smolensk via Warszawa. He conducted a post mortem on the body of a Polish officer, selected by himself. Following that he attended in the discussion on the final report, which later in Berlin was handed over to the German minister of health, and which later formed an important part of the official German material accusing the USSR for the killing.

    White dwarf evolution, particularly in the early phases, is not very strongly constrained by observation. Fortunately, white dwarfs undergo nonradial pulsation in three distinct regions of the H-R diagram. These pulsations provide accurate masses, surface compositional structure and rotation velocities, and help constrain other important physical properties. We demonstrate the application of the tools of stellar seismology to white dwarf evolution using the hot white dwarf star PG 1159-035 and the cool DAV (or ZZ Ceti) stars as examples. From pulsation studies, significant challenges to the theory of white dwarf evolution emerge.

  3. Two grave issues concerning the expected Tokai Earthquake

    Mogi, Kiyoo

    2004-08-01

    The possibility of a great shallow earthquake (M 8) in the Tokai region, central Honshu, in the near future was pointed out by Mogi in 1969 and by the Coordinating Committee for Earthquake Prediction (CCEP), Japan (1970). In 1978, the government enacted the Large-Scale Earthquake Countermeasures Law and began to set up intensified observations in this region for short-term prediction of the expected Tokai earthquake. In this paper, two serious issues are pointed out, which may contribute to catastrophic effects in connection with the Tokai earthquake: 1. The danger of black-and-white predictions: According to the scenario based on the Large-Scale Earthquake Countermeasures Law, if abnormal crustal changes are observed, the Earthquake Assessment Committee (EAC) will determine whether or not there is an imminent danger. The findings are reported to the Prime Minister who decides whether to issue an official warning statement. Administrative policy clearly stipulates the measures to be taken in response to such a warning, and because the law presupposes the ability to predict a large earthquake accurately, there are drastic measures appropriate to the situation. The Tokai region is a densely populated region with high social and economic activity, and it is traversed by several vital transportation arteries. When a warning statement is issued, all transportation is to be halted. The Tokyo capital region would be cut off from the Nagoya and Osaka regions, and there would be a great impact on all of Japan. I (the former chairman of EAC) maintained that in view of the variety and complexity of precursory phenomena, it was inadvisable to attempt a black-and-white judgment as the basis for a "warning statement". I urged that the government adopt a "soft warning" system that acknowledges the uncertainty factor and that countermeasures be designed with that uncertainty in mind. 2. The danger of nuclear power plants in the focal region: Although the possibility of the occurrence of a great shallow earthquake in the Tokai region was pointed out by CCEP in 1970, soon after, plans for construction of a nuclear power plant started in this region. Since 1976, Hamaoka nuclear power plants (Units 1˜4) have been operating near the center of the expected focal region of the great Tokai earthquake, and Unit 5 is under construction. This is quite a dangerous situation.

    Often expected to work institutional miracles although under resourced, most hospice and palliative care nurses excel in meeting consistently intense and demanding clinical and human challenges. They do so by staying focused and being grounded, highly accountable, responsive, and empathetic. With time and experience, they often master the art of advocacy, and through developing a capacity for "organization-with-heart," they navigate very complex institutional, systemic, cultural, and societal waters. Nurses are present to patient and familial wounds; the sights, sounds, smells of chaos and beauty; gladness and grief; intimacy and numbness. Our guest author today distills years of nursing experience into a very few words that can be shared in classrooms, homes, and clinics. It is clear that she not only knows of what she speaks, but, having died many times to that which is not fruitful, she separates the essential from the nonessential and, in so doing, is renewed and full of life. Isn't this an ultimate demonstration of integration and embodiment? Therese Schroeder-Sheker, The Chalice of Repose Project. PMID:16781537

    Myasthenia gravis (MG) is a prototypic autoimmune disease with overt clinical and immunological heterogeneity. The data of MG is far from individually precise now, partially due to the rarity and heterogeneity of this disease. In this review, we provide the basic insights of MG data precision, including onset age, presenting symptoms, generalization, thymus status, pathogenic autoantibodies, muscle involvement, severity and response to treatment based on references and our previous studies. Subgroups and quantitative traits of MG are discussed in the sense of data precision. The role of disease registries and scientific bases of precise analysis are also discussed to ensure better collection and analysis of MG data. PMID:27127759

    A potential complication of subtotal thyroidectomy where a large pyramidal lobe is present is described. The pyramidal lobe normally is immobilized inferiorly by its attachment to the thyroidal isthmus. When the isthmus is removed and the pyramidal lobe is left in situ during subtotal thyroidectomy its superior attachments will allow the pyramidal lobe to become situated sublingually. This may produce gagging and nausea. To avoid the complication, it is recommended that the pyramidal lobe be removed during subtotal thyroidectomy. If the patient also is thyrotoxic, I-131 can be used to treat this complication successfully.

    A 28-year-old patient showed clear signs of knee joint infection 8 days after arthroscopic reconstruction of the anterior cruciate ligament. The treating physicians recommended further observation although they stated that a knee joint infection could not be reliably excluded. One week later arthroscopic revision was performed and intraoperative smear tests showed infection by Pseudomonas aeruginosa. Therefore, another 6 days later the obviously infected transplant had to be removed. In the long run painful and limited range of motion of the affected knee joint persisted. The patient complained about medical malpractice concerning management of the complication. The expert opinion stated that due to the fateful course of infection the tendon graft could not be retrieved after the eighth day post surgery anyway. Thus, only flawed delay of treatment was criticized. The arbitration board argued, however, that scientific data concerning the fate of infected tendon grafts do not support the expert opinion and that immediate arthroscopy and antibiotic treatment at least had the potential to influence the course of infection in a positive manner. Evidence clearly shows that survival of an infected tendon graft depends on early diagnosis and emergency treatment rather than just on fate. Due to the fact that, although having in mind the possibility of a knee joint infection, the necessary therapy was delayed for 8 days, the arbitration board considered the described medical malpractice a severe treatment error, leading to reversal of evidence in favour of the patient.

    Carbon cycling in the rhizosphere is a nexus of biophysical interactions between plant roots, microorganisms, and the soil organo-mineral matrix. Plant roots are the primary inputs of soil organic C; the presence of roots significantly alters rates of organic matter mineralization by soil microbes. Our research on how roots influence decomposition of soil organic matter in both simplified and complex microcosms uses geochemical characterization, molecular microbiology, isotope tracing, 'omics and novel imaging approaches ('ChipSIP' and 'STXM-SIMS') to trace the fate of isotopically labelled root exudates and plant tissues. Our work seeks to understand the genomic basis for how organic C transformation and decomposition in soil is altered by interactions between plant roots and the soil microbial community (bacteria, archaea, fungi, microfauna). We hypothesize that root-exudate stimulation of soil microbial populations results in the altered expression of transcripts and proteins involved in decomposition of macromolecular C compounds. Using an isotope array that allows us to follow root C into bacterial, fungal, and microfaunal communities, we have tracked movement of 13C from labeled exudates and 15N from labeled root litter into the soil microbial community, and linked this data to 16S profiles and community gene transcripts. By integrating stable isotopes as tracers of natural resource utilization (i.e. root litter), and analysis of the functional properties of the communities that respond to those resources, we can identify the molecular pathways that are stimulated in the soil microbiome in response to root litter, living roots, and their interfaces.

    Summary The incorrect position of the foot in talipes equinus is common in the framework of prolonged confinement to bed in a patient in deep sedation. In the context of severe burns, this incorrect position is difficult to prevent and its fixation by cutaneous shrinkage, which is often associated with a musculotendinous fibrosis, constitutes an important functional after-effect. The onset of talipes equinus is insidious and progressive, and it is therefore important to be watchful both in detection and in prevention. Regular photographic assessment makes it possible to predict its appearance and to take appropriate preventive or curative action. PMID:21991119

    We extracted DNA from three skeletons belonging to the Yakut population, which were excavated from the At-Dabaan site (dating back 300 years) in the Sakha Republic (Russia). Ancient DNA was analyzed by autosomal STRs (short tandem repeats) and by the sequencing of the hypervariable region 1 (HV1) of the mitochondrial DNA (mtDNA) control region. The results showed that these three skeletons were not close relatives but probably linked to the same clan structure. Comparison of their haplotypes with the haplotypes of 8,774 Eurasian individuals suggested a relative specificity and continuity of part of the Yakut mitochondrial gene pool during the last 3 centuries.

    Objective. GD with ATD-induced hepatic injury or leukopenia occurs frequently in clinical practice. The purpose of the present study was to observe the clinical effect of lithium carbonate on hyperthyroidism in patients with GD with hepatic injury or leukopenia. Methods. Fifty-one patients with GD with hepatic injury or leukopenia participated in the study. All patients were treated with lithium carbonate, in addition to hepatoprotective drugs or drugs that increase white blood cell count. Thyroid function, liver function, and white blood cells were measured. Clinical outcomes were observed after a 1-year follow-up. Results. After treatment for 36 weeks, symptoms of hyperthyroidism and the level of thyroid hormones were improved and liver function, and white blood cells returned to a normal level. Twelve patients (23.5%) obtained clinical remission, 6 patients (11.8%) relapsed after withdrawal, 25 patients (49.0%) received radioiodine therapy, and 8 patients (15.7%) underwent surgical procedures after lithium carbonate treatment. Conclusion. Lithium carbonate has effects on the treatment of mild-to-moderate hyperthyroidism caused by GD, and it is particularly suitable for patients with ATD-induced hepatic injury or leukopenia.

    2016-06-01

    Hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal syndrome seen primarily in children. It is characterized by pathologic systemic hyper inflammation which in adults is easily overlooked due to non-specific clinical features. Most of the data available are on paedriatic population, making the diagnosis of HLH in adults challenging for the clinician. Here we report a case of HLH in a 48-year male who presented with pyrexia of unknown origin for 2 months but remained undiagnosed despite extensive workup. Due to a high index of suspicion, re-evaluation of bone marrow biopsy was done which showed hemophagocytosis, earlier reported as normal. It led to specific investigations, needed for establishing the diagnostic criteria of HLH. Even though chemotherapy was initiated, the patient did not survive. The aggressive nature of this disease makes it crucial for the physician to be aware of its signs and symptoms for the early diagnosis and immediate introduction of adequate treatment. PMID:27376224

  20. From Cradle to Grave: Research on Atmospheric Aerosols (Vilhelm Bjerknes Medal Lecture)

    2014-05-01

    Atmospheric aerosol particles are liquid or solid particles suspended in the atmosphere. Generally, the sizes of aerosol particles are in the range 0.001 - 100 μm. Atmospheric aerosols are of interest mainly because of their effects on health and climate. Concerning health, many epidemiological studies have shown a link between increased mortality/morbidity and increased PM10 or PM2.5 (particulate matter with an aerodynamic diameter smaller than 10 and 2.5 μm, respectively). Concerning climate, aerosol particles scatter and absorb light (known as the direct effect on climate), and modify cloud properties (with a variety of effects known as indirect effects). These effects are influenced by the chemical and physical properties of the aerosol particles, which makes these properties important to be measured. Atmospheric aerosol particles are produced by a large variety of sources, and are either emitted as primary particles (i.e., they are directly emitted as particles into the atmosphere) or formed by secondary processes (i.e., by transformation of emitted precursor gases). While the formation pathways of secondary inorganic aerosols such as nitrate and sulfate in general are reasonably well understood, the formation of secondary organic aerosol (SOA) is still an area of active research. A wide variety of gaseous precursors contribute to SOA, and their aerosol yields depend on a wide variety of conditions. In addition, it is still largely unknown to which extent and under which conditions oxidized organic molecules can contribute to nucleation, i.e., the formation of new particles. Elimination of aerosol particles from the atmosphere mostly occurs by wet deposition, where the ice phase plays an important role. Even though cloud glaciation augments precipitation formation and affects cloud radiative properties little is still known about mixed-phase cloud formation via heterogeneous nucleation. To elucidate some of the involved mechanisms in situ research in such mixed phase clouds has been performed in a series of Cloud Aerosol Characterization Experiments (CLACE) at the high altitude research station Jungfraujoch (3580 m asl). This presentation will give an overview on recent laboratory experiments and field campaigns. The lab studies relate to SOA formation from a variety of precursors as well as the formation of new particles from gaseous sulfuric acid in combination with other precursor gases where the latter experiments have been performed in the CLOUD experiment at CERN. The field studies relate to the latest developments of source apportionment studies for the organic aerosol, which build on positive matrix factorization of aerosol mass spectrometer data, as well as to aerosol cloud interaction studies on the Jungfraujoch.

    Graves’ disease (GD) may be observed as an infrequent adverse effect after radioiodine therapy (RAIT) for toxic thyroid adenoma (TA) and toxic multi nodular goiter (MNG). We present a case of a 55-year-old male with a toxic nodule who was treated with RAI. After therapy, the patient’s serum free triiodothyronine (fT3) and free thyroxine (fT4) levels gradually increased. Antithyroid peroxidase (TPOAb), antithyroglobulin (TgAb) and TSH-receptor antibodies (TRAb) were also positive. Thyroid scintigraphy revealed diffuse intense uptake after four months of RAIT. Radiation-induced GD should be considered in patients with aggravated hyperthyroidism 3-4 months after therapy.

  7. Fluid Simulation in the Movies: Navier and Stokes Must Be Circulating in Their Graves

    NASA Astrophysics Data System (ADS)

    Tessendorf, Jerry

    2010-11-01

    Fluid simulations based on the Incompressible Navier-Stokes equations are commonplace computer graphics tools in the visual effects industry. These simulations mostly come from custom C++ code written by the visual effects companies. Their significant impact in films was recognized in 2008 with Academy Awards to four visual effects companies for their technical achievement. However artists are not fluid dynamicists, and fluid dynamics simulations are expensive to use in a deadline-driven production environment. As a result, the simulation algorithms are modified to limit the computational resources, adapt them to production workflow, and to respect the client's vision of the film plot. Eulerian solvers on fixed rectangular grids use a mix of momentum solvers, including Semi-Lagrangian, FLIP, and QUICK. Incompressibility is enforced with FFT, Conjugate Gradient, and Multigrid methods. For liquids, a levelset field tracks the free surface. Smooth Particle Hydrodynamics is also used, and is part of a hybrid Eulerian-SPH liquid simulator. Artists use all of them in a mix and match fashion to control the appearance of the simulation. Specially designed forces and boundary conditions control the flow. The simulation can be an input to artistically driven procedural particle simulations that enhance the flow with more detail and drama. Post-simulation processing increases the visual detail beyond the grid resolution. Ultimately, iterative simulation methods that fit naturally in the production workflow are extremely desirable but not yet successful. Results from some efforts for iterative methods are shown, and other approaches motivated by the history of production are proposed.

    Purpose: The precise determination of organ mass (m{sub th}) and total number of disintegrations within the thyroid gland (A{sup ~}) are essential for thyroid absorbed-dose calculations for radioiodine therapy. Nevertheless, these parameters may vary according to the method employed for their estimation, thus introducing uncertainty in the estimated thyroid absorbed dose and in any dose–response relationship derived using such estimates. In consideration of these points, thyroid absorbed doses for Graves’ disease (GD) treatment planning were calculated using different approaches to estimating the m{sub th} and the A{sup ~}. Methods: Fifty patients were included in the study. Thyroid{sup 131}I uptake measurements were performed at 2, 6, 24, 48, 96, and 220 h postadministration of a tracer activity in order to estimate the effective half-time (T{sub eff}) of {sup 131}I in the thyroid; the thyroid cumulated activity was then estimated using the T{sub eff} thus determined or, alternatively, calculated by numeric integration of the measured time-activity data. Thyroid mass was estimated by ultrasonography (USG) and scintigraphy (SCTG). Absorbed doses were calculated with the OLINDA/EXM software. The relationships between thyroid absorbed dose and therapy response were evaluated at 3 months and 1 year after therapy. Results: The average ratio (±1 standard deviation) betweenm{sub th} estimated by SCTG and USG was 1.74 (±0.64) and that between A{sup ~} obtained by T{sub eff} and the integration of measured activity in the gland was 1.71 (±0.14). These differences affect the calculated absorbed dose. Overall, therapeutic success, corresponding to induction of durable hypothyroidism or euthyroidism, was achieved in 72% of all patients at 3 months and in 90% at 1 year. A therapeutic success rate of at least 95% was found in the group of patients receiving doses of 200 Gy (p = 0.0483) and 330 Gy (p = 0.0131) when m{sub th} was measured by either USG or SCTG and A{sup ~} was determined by the integration of measured {sup 131}I activity in the thyroid gland and based on T{sub eff}, respectively. No statistically significant relationship was found between therapeutic response and patients’ age, administered {sup 131}I activity (MBq), 24-h thyroid {sup 131}I uptake (%) or T{sub eff} (p ≥ 0.064); nonetheless, a good relationship was found between the therapeutic response and m{sub th} (p ≤ 0.035). Conclusions: According to the results of this study, the most effective thyroid absorbed dose to be targeted in GD therapy should not be based on a fixed dose but rather should be individualized based on the patient'sm{sub th} and A{sup ~}. To achieve a therapeutic success (i.e., durable euthyroidism or hypothyroidism) rate of at least 95%, a thyroid absorbed dose of 200 or 330 Gy is required depending on the methodology used for estimating m{sub th} and A{sup ~}.

    Epitaphs and memorials as immovable items in sacred spaces provide with their inscriptions valuable documents of history. Today not only photography or photos are suitable as presentation material for cultural assets in museums. Computer vision and photogrammetry provide methods for recording, 3D modelling, rendering under artificial light conditions as well as further options for analysis and investigation of artistry. For exhibition purposes epitaphs have been recorded by the structure from motion method. A comparison of different kinds of SFM software distributions could be worked out. The suitability of open source software in the mesh processing chain from modelling up to displaying on computer monitors should be answered. Raspberry Pi, a computer in SoC technology works as a media server under Linux applying Python scripts. Will the little computer meet the requirements for a museum and is the handling comfortable enough for staff and visitors? This contribution reports about the case study.

    The report analyzes the controversy over black lung disease among U.S. coal miners, situated within the recent struggle over industrial relations in bituminous coal. Summaries of the postwar coal industry and the changing medical approach to black lung provide the historical backdrop to the recent controversy. The development of the black lung movement is reconstructed primarily through material from oral interviews with its participants. The movement is viewed essentially as a class conflict between miners and operators over who would bear the burden of occupational disease: miners, by continuing to be disabled and without compensation; or the operators, by reducing dust levels in the mines and financing benefits for disabled workers.

  11. Tales from the grave: Opposing autopsy reports from a body exhumed.

    2012-07-01

    We report an autopsy case of a 42-year-old woman who, when discovered, had been dead in her apartment for approximately 1 week under circumstances involving treachery, assault and possible drug overdose. This case is unique as it involved two autopsies of the deceased by two different medical examiners who reached opposing conclusions. The first autopsy was performed about 10 days after death. The second autopsy was performed after an exhumation approximately 2 years after burial. Evidence collected at the crime scene included blood samples from which DNA was extracted and analysed, fingerprints and clothing containing dried body fluids. The conclusion of the first autopsy was accidental death due to cocaine toxicity; the conclusion of the second autopsy was death due to homicide given the totality of evidence. Suspects 1 and 2 were linked to the death of the victim by physical evidence and suspect 3 was linked by testimony. Suspect 1 received life in prison, and suspects 2 and 3 received 45 and 20 years in prison, respectively. This case indicates that cocaine toxicity is difficult to determine in putrefied tissue and that exhumations can be important in collecting forensic information. It further reveals that the combined findings of medical examiners, even though contradictory, are useful in determining the circumstances leading to death in criminal justice. Thus, this report demonstrates that such criminal circumstances require comparative forensic review and, in such cases, scientific conclusions can be difficult. PMID:22687773

    Embolism of fat and bone marrow tissue is quite often due to bone fractures but it is seldom with signs of systemic involvement as a fat embolism syndrome. The main forming factor is late stabilization of fractures and hypovolemia too. Clinical image of fat embolism syndrome results from lung and systemic microembolism which leads to activation of inflammatory and thrombogenic cascades. We present a case report of a 24-year-old male after bike accident in low speed suffering from isolated thighbone fracture--osteosynthesis was applied in 6 hours after injury. The very first day the organ failure and coma with negative CT occurred, then ARDS, petechiae into the skin of chest and conjunctiva, also embolic closure of a. centralis retinae. Treatment interventions included anticoagulation, steroids, artificial ventilation for 17 days. After 3 weeks from injury he was still unconscious (with GCS 10) so that we tried a hyperbaric oxygen therapy. The patient regained consciousness after 3 months after injury. One year later he is able to walk alone, he has no visual failure, but he is still quadruspastic although able to manipulate with a mobile phone. We discuss diagnostic criteria and treatment. We also point out need of volumetherapy in prevention of fat embolism syndrome--this was underrated here because of primary missed out diagnose of co-existing tibia fracture at the same time (this was stabilised 18 hours after injury).

    Carbon cycling in the rhizosphere is a nexus of biophysical interactions between plant roots, microorganisms, and the soil organo-mineral matrix. Plant roots provide 30-40% of soil organic C inputs, accelerate the rate of organic matter mineralization by ~10X, and support an active microhabitat for microbial transformation of soil C. Our research on how roots influence decomposition of soil organic matter in both simplified and complex microcosms uses geochemical characterization, molecular microbiology, isotope tracing, metabolomics and novel imaging approaches (';ChipSIP' and ';STXM-SIMS') to trace the fate of isotopically labelled root exudates and plant tissues. Our previous work suggests root exudates drive O2 limitation, alter metal chemistry and mineralogy, and influence the availability of SOM. Our most recent experiments using synthetic rhizospheres were designed to identify the role of root exudates on ligno-cellulose decomposition in soils. Cultures of 13C/15N-labeled single plant cells (lignin-rich tracheary elements) were added to rhizosphere microcosm soils, and their decomposition followed under the influence of different root exudates using the dual imaging approach ';STXM-SIMS'. Using this combination of X-ray spectromicroscopy and NanoSIMS, we imaged the deconstruction of 13C/15N-labeled ligno-cellulose in situ, and mapped associations of plant cell-derived decomposition products with specific soil minerals. We've also looked at microbial community function in the more complex rhizospheres surrounding roots of the annual grass Avena fatua. Using an isotope array that allows us to follow root C into bacterial, fungal, and microfaunal communities, we tracked the movement of 13C from labeled exudates and 15N from labeled root litter into the soil microbial community. Our results indicate that the microbial communities involved in litter decomposition differ in rhizosphere versus bulk soils, which may have implications for carbon stabilization in soil.

    Perdigões is a large site with a set of ditched enclosures located at Reguengos de Monsaraz, Alentejo, South Portugal. Recently at the central area of this site burnt human remains were found in a pit (#16). This structure had inside human remains, animal bones (namely pig, sheep or goat, cattle, dog, deer and rabbit), shards, ivory idols and arrowheads. All have been subjected to fire and later deposited in that pit, resulting in a secondary disposal of human bones. The recovered fragmented human bones (4845.18 g) correspond to a minimal number of 9 individuals: 6 adults and 3 sub-adults. The aim of this work is to document and interpret this funerary context based on the study of the recovered human remains. For that purpose, observations of all alterations due to fire, such as colour change and type of bone distortion, as well as anthropological data were collected. The data obtained suggest that these human remains were probably intentionally cremated, carefully collected and finally deposited in this pit. The cremation was conducted on probably complete corpses, some of them still fairly fresh and fleshed, as some bones presented thumbnail fractures. The collective cremation of the pit 16 represents an unprecedented funerary context for Portuguese, and Iberian Peninsula, Chalcolithic burial practices. Moreover, it is an example of the increasing diversity of mortuary practices of Chalcolithic human populations described in present Portuguese territory, as well as, in the Iberian Peninsula.

    Highlights: • We model environmental impacts of leaching from secondary construction material. • Industrial wastes in construction contain up to 45,000 t heavy metals per year (D). • In a scenario, 150 t are leached to the environment within 100 years after construction. • All heavy metals but As, Sb and Mo are adsorbed by 20 cm subsoil in this scenario. • Environmental impacts depend on material, pollutant, construction type, and geography. - Abstract: In industrialized countries, large amounts of mineral wastes are produced. They are re-used in various ways, particularly in road and earth constructions, substituting primary resources such as gravel. However, they may also contain pollutants, such as heavy metals, which may be leached to the groundwater. The toxic impacts of these emissions are so far often neglected within Life Cycle Assessments (LCA) of products or waste treatment services and thus, potentially large environmental impacts are currently missed. This study aims at closing this gap by assessing the ecotoxic impacts of heavy metal leaching from industrial mineral wastes in road and earth constructions. The flows of metals such as Sb, As, Pb, Cd, Cr, Cu, Mo, Ni, V and Zn originating from three typical constructions to the environment are quantified, their fate in the environment is assessed and potential ecotoxic effects evaluated. For our reference country, Germany, the industrial wastes that are applied as Granular Secondary Construction Material (GSCM) carry more than 45,000 t of diverse heavy metals per year. Depending on the material quality and construction type applied, up to 150 t of heavy metals may leach to the environment within the first 100 years after construction. Heavy metal retardation in subsoil can potentially reduce the fate to groundwater by up to 100%. One major challenge of integrating leaching from constructions into macro-scale LCA frameworks is the high variability in micro-scale technical and geographical factors, such as material qualities, construction types and soil types. In our work, we consider a broad range of parameter values in the modeling of leaching and fate. This allows distinguishing between the impacts of various road constructions, as well as sites with different soil properties. The findings of this study promote the quantitative consideration of environmental impacts of long-term leaching in Life Cycle Assessment, complementing site-specific risk assessment, for the design of waste management strategies, particularly in the construction sector.

    In most long-lived animal species, juveniles survive less well than adults. A potential mechanism is inferior foraging skills but longitudinal studies that follow the development of juvenile foraging are needed to test this. We used miniaturized activity loggers to record daily foraging times of juvenile and adult European shags Phalacrocorax aristotelis from fledging to the following spring. Juveniles became independent from their parents 40 days post-fledging. They compensated for poor foraging proficiency by foraging for approximately 3 h d(-1) longer than adults until constrained by day length in early November. Thereafter, juvenile foraging time tracked shortening day length up to the winter solstice, when foraging time of the two age classes converged and continued to track day length until early February. Few individuals died until midwinter and mortality peaked in January-February, with juvenile mortality (including some of the study birds) five times that of adults. In their last two weeks of life, juveniles showed a marked decline in foraging time consistent with individuals becoming moribund. Our results provide compelling evidence that juveniles compensate for poor foraging proficiency by increasing foraging time, a strategy that is limited by day length resulting in high winter mortality.

    Sounding rockets in university research provide a unique opportunity to train future space scientists and engineers. Besides fitting the typical schedule of a student, they allow a small group of students to be involved in all aspects of a space project from its inception through execution to a conclusion involving scientific discovery. Furthermore, universities with sounding rocket programs are cradles of innovations where the interdisciplinary nature of space experimentation is nurtured. These programs have formed the core research of many of the current Principal Investigators of NASA Space Science Missions. Additionally, they typically involve a large number of undergraduate students who gain in-depth experience into well-defined and critical components of a space mission. Researchers involved in sounding rocket experiments typically develop the science payload consisting of one or more instrument with the NASA Sounding Rocket Program Office (SRPO) providing all support necessary to make the science program a success. Unlike satellite missions, the sounding rocket experiments offer an opportunity to take more risks in terms of their science return. Some of these risks come in the form of new technology invention and development. Sounding rockets, with their flexible schedule and fewer formal procedural requirements, thus play an important role in maturing technology and developing new capabilities for satellite missions. The Student Launch Program was designed by NASA to provide a new opportunity where space science took a back seat to education and training. The program required that the proposing team provide components such as the nose cone, power and telemetry systems, which are typically provided to rocket experimenters by SRPO. The students involved in such programs thus gained invaluable experience with "mini-satellite" missions. We believe that they are essential for the long-term vitality of the space program and maintaining a technology-savvy workforce of the 21st Century. In this talk we will highlight the unique aspects of several sounding rocket experiments. We will also describe a Student Launch Program where the proposal was developed as a class project in the astronomy department at Boston University and the flight hardware were built through the Senior Design Projects class in the College of Engineering.

    Engineered nanomaterials (ENMs) promise great benefits for society, yet our knowledge of potential risks and best practices for regulation are still in their infancy. Toward the end of better practices, this paper analyzes U.S. federal environmental, health, and safety (EHS) regulations using a life cycle framework. It evaluates their adequacy as applied to ENMs to identify gaps through which emerging nanomaterials may escape regulation from initial production to end-of-life. High scientific uncertainty, a lack of EHS and product data, inappropriately designed exemptions and thresholds, and limited agency resources are a challenge to both the applicability and adequacy of current regulations. The result is that some forms of engineered nanomaterials may escape federal oversight and rigorous risk review at one or more stages along their life cycle, with the largest gaps occurring at the postmarket stages, and at points of ENM release to the environment. Oversight can be improved through pending regulatory reforms, increased research and development for the monitoring, control, and analysis of environmental and end-of-life releases, introduction of periodic re-evaluation of ENM risks, and fostering a "bottom-up" stewardship approach to the responsible management of risks from engineered nanomaterials.

    Historically serving as repositories for morphologically-based taxonomic research, natural history collections are now increasingly being targeted in studies utilizing DNA data. The development of advanced molecular techniques has facilitated extraction of useable DNA from old specimens, including type material. Sequencing diagnostic molecular markers from type material enables accurate species designation, especially where modern taxonomic hypotheses confirm morphologically cryptic species complexes. One such example is Chrysoperla carnea (Stephens), which belongs to a complex of about 20 cryptic species, most of which can only be reliably distinguished by their pre-mating courtship songs or by DNA analysis. The subtle morphological variation in the group has led to disagreement over the previous designation of the lectotype for C. carnea, an issue that has been further compounded because Chrysoperla carnea is a highly valued biological control agent in arable crops. Archival DNA extraction and sequencing from the 180 year old lectotype specimen, combined with Bayesian and Likelihood based phylogenetic analyses of modern specimens from the entire complex, were used to establish unambiguously the true identity of Chrysoperla carnea.

  6. Storm deposits as graves in Early Life: the Fezouata Lagerstätte case (Lower Ordovician, Morocco)

    The Fezouata Shale (Early Ordovician, Morocco) is renowned in the palaeontological community for its Konservat-Lagerstätte (Tremadocian in age) that yielded thousands of exceptionally well-preserved fossils (EPF) from the Great Ordovician Biodiversification Event. Lower Ordovician deposits in the central Anti-Atlas Mountain (Zagora area) are expressed by the Fezouata Shale and the Zini Formation. They consist in ca. 900m of siltstones and sandstones deposited in an epicontinental sea at the periphery of the Gondwanaland. Sedimentologic field analysis and sequence analysis were achieved on ten stratigraphic sections in order to constrain the palaeoenvironmental context of the Fezouata Biota and to predict the location (geographically and stratigraphically) of new Lagerstätten. Sedimentary structures (cm- to m-scale symmetrical ripples) and geometries (lobe, lobe-channel) point to storm dominance on the sedimentation but peculiar sedimentary features suggest a tide modulation. Thus, a wave-dominated tide-modulated model of deposition recording proximal offshore to shoreface environments for the Fezouata Shale and shoreface to foreshore environments for the overlying Zini Fm is proposed. Layers yielding EPF are argillaceous siltstones (with wave ripples of cm-scale wavelength) always overlain by fine-grained sandstones (distal storm deposits, few cm-thick, several m-long, with cm- to dm-scale hummocky cross-stratifications). Fast burying by storm deposits appear to be of prime importance to initiate the exceptional preservation of the soft tissues of animals in the fossil record. According to the model of deposition it correspond to environments close to the storm weather wave base. Lower Ordovician succession was deposited during a 2nd order cycle, although 3rd and 4th order cycles were also identified. Encoding these different orders of sea level fluctuations giving a value of "1" for the deepest part of sequences (for each order) and a value of "0" for the shallowest, a reconstruction of the sea level fluctuation is then proposed. This reconstruction clearly highlights the stratigraphic position of the today discovered Lagerstätte. It also suggests that a second, younger (Floian in age) stratigraphic interval has very comparable sedimentary conditions in terms of facies and sea level, and has the potential for being a new Lagerstätte in the Fezouata Shale.

    The partially earth-directed coronal mass ejection (CME) event of 1997 February 6-7 originated from the southwest quadrant of the sun. The CME accelerated from 170 km/s to about 830 km/s when it reached a distance of 25 solar radii. The CME was an arcade eruption followed by bright prominence core structures. The prominence core was tracked continuously from the solar surface to the interplanetary medium by combining data from the Nobeyama radioheliograph (microwaves), Mauna Loa Solar Observatory (He 10830 { Angstroms}), SOHO/EIT (EUV) and SOHO/LASCO (white light). The CME was accompanied by an arcade formation, fully observed by the YOHKOH/SXT (soft X-rays) and SOHO/EIT (EUV). The X-ray and EUV observations suggest that the reconnection proceeded from the northwest end to the southeast end of a filament channel. In the SOHO/EIT images, the the feet of the soft X-ray arcade were observed as EUV ribbons. The CME event also caused a medium sized geomagnetic storm: The hourly equatorial Dst values attained storm level during 18:00-19:00 UT on February 09. This means the disturbance took about 2.25 days to reach the Earth. The first signatures of an IP shock was a pressure jump in the WIND data around 13:00 UT on Feb 09, 1997 which lasted for about 14 hours, followed by flux rope signatures. This CME event confirms a number of ideas about CMEs: The three part structure (frontal bright arcade, dark cavity and prominence core), disappearing filament, elongated arcade formation, and terrestrial effects. We make use of the excellent data coverage from the solar surface to the Earth to address a number of issues regarding the origin and propagation of the geoeffective solar disturbances. We benefited from discussions at the first SOHO-Yohkoh Coordinated Data Analysis Workshop, held March 3-7, 1997, at Goddard Space Flight Center.

  10. America, you are digging your grave with your spoon--should the FDA tell you that on food labels?

    PubMed

    Card, Melissa M

    2013-01-01

    R.J. Reynolds Tobacco Co. v. Food & Drug Admin. discussed whether the FDA's promulgation of graphic images violated tobacco companies' First Amendment rights. While the tobacco companies contested the graphic images, the tobacco companies did not contest the promulgation of nine textual statements about the adverse effects of cigarettes. This uncontested mandate opens a door for the FDA to further expand its regulatory scheme. If the FDA can mandate textual statements about the adverse effects of cigarettes, can the FDA mandate textual statements about the adverse effects of sugar to combat the obesity crisis? This Article presents three textual statements about the adverse effects of sugar, to define the line between acceptable and unacceptable forms of compelled commercial speech under Central Hudson. Establishing this line ensures that the commercial speech doctrine does not deny the FDA from its authority to provide consumers with accurate information. While three textual statements are presented, this Article advocates that one of the textual statements is likely to serve as the best solution to the obesity crisis. The chosen textual statement serves as an effective solution because it presents meaningful information to the consumers enabling consumers to make healthful decisions about their food and encourages manufacturers to modify their products.

    A monoclonal antibody (LE4) specific for a thyrotropin (TSH) epitope shared by beta subunits of bovine (b), ovine (o), and human (h) TSH was obtained by immunization of mice with mixtures of purified bTSH and hTSH. LE4 also bound the beta subunits of bovine, ovine, and human lutropin (LH), and human chorionic gonadotropin (hCG) but not the beta subunits of porcine LH and TSH. Preliminary studies with deglycosylated (dg) bTSH and dg-hCG indicated that part of the epitope may be carbohydrate. Preincubation of LE4 with (/sup 125/I)bTSH inhibited the binding of the hormone to TSH receptor of bovine thyroid membranes in a dose-dependent manner. LE4 also inhibited TSH-induced mitogenesis of FRTL-5 cells. We conclude that LE4 binds to a site on the bTSH molecule that participates in high affinity binding of hormone to TSH receptor.

    The older of a pair of sisters experienced hypoglycemia after the start of thiamazole (MMI) treatment. Based on a high insulin antibody level, she was diagnosed with insulin autoimmune syndrome (IAS). HLA-DNA typing identified DRB1*04:06. Although a 75-g oral glucose tolerance test (OGTT) showed biphasic insulin secretion, the secretion pattern became monophasic after discontinuation of the MMI. The younger sister was diagnosed with IAS after the start of MMI treatment. HLA-DNA typing identified DRB1*04:06. The 75-g OGTT showed biphasic insulin secretion, but it became monophasic after discontinuation of the MMI. According to the similar insulin secretion kinetics in the two sisters with IAS, we suspect that a genetic predisposition may be associated with the features of anti-insulin antibodies.

    A 48-year-old woman with a history of diabetes was admitted for nausea and vomiting with body weight loss. A blood examination revealed high plasma glucose and thyroid hormone levels and metabolic acidosis. She was therefore diagnosed with both diabetic ketoacidosis (DKA) and hyperthyroidism. Nausea and vomiting continued intermittently despite the administration of saline and insulin. The patient was further diagnosed with superior mesenteric artery syndrome (SMAS) after abdominal computed tomography revealed that a horizontal portion of the duodenum was sandwiched between the aorta and the superior mesenteric artery. Clinicians should be vigilant for SMAS in patients with both DKA and hyperthyroidism who present body weight loss. PMID:27477411

    Introduction We describe three different fetal or neonatal outcomes in the offspring of a mother who had persistent circulating thyrotropin receptor antibodies despite having undergone a total thyroidectomy several years before. Case presentation The three different outcomes were an intrauterine death, a mild and transient fetal and neonatal hyperthyroidism and a severe fetal and neonatal hyperthyroidism that required specific therapy. Conclusions The three cases are interesting because of the different outcomes, the absence of a direct correlation between thyrotropin receptor antibody levels and clinical signs, and the persistence of thyrotropin receptor antibodies several years after a total thyroidectomy.

    Background Ample evidence has shown that early-life social conditions are associated with mortality later in life. However, little attention has been given to the strength of these effects across specific age intervals from birth to old age. In this paper, we study the effect of the family's socioeconomic position and mother's marital status at birth on all-cause mortality at different age intervals in a Swedish cohort of 11 868 individuals followed across their lifespan. Methods Using the Uppsala Birth Cohort Multigenerational Study, we fitted Cox regression models to estimate age-varying HRs of all-cause mortality according to mother's marital status and family's socioeconomic position. Results Mother's marital status and family's socioeconomic position at birth were associated with higher mortality rates throughout life (HR 1.18 (95% CI 1.12 to 1.26) for unmarried mothers; 1.19 (95% CI 1.12 to 1.25) for low socioeconomic position). While the effect of family's socioeconomic position showed little variation across different age groups, the effect of marital status was stronger for infant mortality (HR 1.47 (95% CI 1.23 to 1.76); p=0.04 for heterogeneity). The results remained robust when early life and adult mediator variables were included. Conclusions Family's socioeconomic position and mother's marital status involve different dimensions of social stratification with independent effects on mortality throughout life. Our findings support the importance of improving early-life conditions in order to enhance healthy ageing. PMID:26733672

    L'incompatibilité fœto-maternelle Rhésus peut être à l'origine d'un syndrome hémolytique dont l'expression clinique est l′anémie fœtale éventuellement compliquée par une anasarque fœto-placentaire ou à l'extrême une mort fœtale in utéro. Nous rapportons l'observation d'un cas d'allo immunisation Rhésus à 34 SA ayant aboutit un hydrops foetalis, l'extraction fœtale par césarienne en vue d'une exsanguino-transfusion a été réalisée, mais le nouveau né est décédé au cours de l'exsanguino-transfusion. Le dépistage des femmes à risque et l'utilisation d'Immunoglobulines anti D ont permis une réduction importante de l′incidence des accidents d'incompatibilité. La mesure du pic systolique de vélocité dans l'artère cérébrale moyenne a bouleversé la surveillance et la prise en charge prénatale des anémies fœtales secondaires à une allo-immunisation Rhésus. Son utilisation dans la surveillance des cas d'allo-immunisation Rhésus permettrait ainsi de réserver les procédures invasives (cordocentèse) comme geste thérapeutique qui permet la transfusion fœtale in utéro. Grâce à une collaboration multidisciplinaire cohérente, l'extraction fœtale peut être programmée, ce qui permet une prise en charge adéquate et rigoureuse, même des nouveaux nés avec atteinte sévère.

    For purposes of recovering correct absorption line strengths for stellar population analysis, emission corrections for Balmer series indices on the Lick index system in Sloan Digital Sky Survey (SDSS) stacked quiescent galaxy spectra are derived as a function of the Mg b index strength. These corrections are obtained by comparing the observed Lick index measurements of the SDSS composite spectra with new observed measurements of 13 Virgo Cluster galaxies, and checked with model grids. From the H{alpha}-Mg b diagram, a linear correction for the observed measurement is constructed using best-fit trend lines. Corrections for H{beta}, H{gamma}, and H{delta} are constructed using stellar population models to predict continuum shape changes as a function of Mg b plus Balmer series emission intensities typical of H II regions. The corrections themselves are fairly secure, but the interpretation for H{delta} and H{gamma} indices is complicated by the fact that the H{delta} and H{gamma} indices are sensitive to elemental abundances other than hydrogen.

    The gold necklace and penannular earrings from tomb 296 at Riqqa, containing the coffins of a female and of a male, the latter a scribe named Beri of the reign of Tuthmosis III (eighteenth Dynasty Egypt), were analysed by PIXE, XRF, and EDS, together with eight penannular earrings from other find-spots of the same period. Analysis of jewellery items from tomb 296 at Riqqa revealed the use of high-purity gold alloys and electrum alloys, while the other earrings investigated were found to be made of electrum with high Ag content. Two earrings conserved in different museums were shown to be originally a pair. PIXE mapping revealed the extensive use of a hard soldering technique for the joints, with the solders being obtained by the addition of Cu to the base alloy. The presence of PGE inclusions indicated the use of alluvial gold, but the variability of their composition could be ascribed to the recycling of gold from different origins, in the case of some objects.

    Graves (1996) developed a multi-echelon inventory model and used a negative binomial distribution to approximate the distribution of a random variable in the model. Two earlier multi-echelon inventory studies (Graves, 1985; Lee and Moinzadeh, 1987) have similarly used negative binomial approximations. Only computational evidence has been offered in support of the approximations. We provide, for the latest model (Graves, 1996), a mathematical analysis of the effectiveness of such an approximation.

  20. GPR Detection and Geophysical Characteristics of Burials in an 19th Century Cemetery

    NASA Astrophysics Data System (ADS)

    2009-12-01

    We conducted a GPR (Ground Penetrating Radar) survey as part of a forensic investigation of the Second Site Cemetery (Rice Cemetery, Hartt Cemetery) in Mecklenburg County, North Carolina. The oldest marked grave at Second Site is 1797, although it is likely that unmarked graves date back to 1780. The most recent marked grave is dated 1848, but forensic evidence suggest that Second Site was in active use until at least the 1880s. The Second Site cemetery contains a "members" section and a "servants" section. The servants section contains graves of slaves, former slaves, and possibly other individuals. Our objectives were to determine the locations of unmarked graves in the servants cemetery, and to define the GPR characteristics that might help distinguish between burials in simple (or no) enclosures and those involving ornamented caskets with hardware. We selected a 15 m by 15 m section of the servants cemetery (Section A) and a second 5 m by 5 m section (Section Z) to conduct GPR surveys, and excavated one grave in each section. Our GPR surveys were done with a GSSI SIR 3000 and a 400 MHz antenna in distance mode. The Section A GPR survey comprised parallel north-south profiles at 0.2 m intervals, and a set of cross lines at 0.5 m spacing. The Section Z profiles were north-south but at a spacing of 0.4 m. Soils in the cemetery are CeB2: Cecil sandy clay loam, clay, clay loam, and sandy loam derived from saprolitized metagranite. We established that a relative permittivity of 3 was suitable for this site at average depths of about 1.5 m, the nominal depth of burial. GPR profiles in both sections revealed some common geophysical characteristics. Most graves are longitudinally oriented east-west. Our north-south profiles therefore define grave lengths. Graves in non-migrated GPR sections are parabolic reflections with lower frequency responses than background. The size, shape, and spectral qualities of these reflections distinguish them from other sources (debris

  13. Characterization of soils containing adipocere.

    PubMed

    Fiedler, S; Schneckenberger, K; Graw, M

    2004-11-01

    The formation of adipocere (commonly known as grave wax), a spontaneous inhibition of postmortem changes, has been extensively analyzed in forensic science. However, soils in which adipocere formation occurs have never been described in detail. Therefore, this study is intended as a first step in the characterization of soils containing adipocere. Two grave soils (Gleyic Anthrosols) that prevent the timely reuse of graves due to the occurrence of adipocere and a control soil (Gleyic Luvisol) were selected from a cemetery in the Central Black Forest (Southwest Germany). Descriptions of soil morphology and a wide assay of physical, chemical, and microbiologic soil characteristics were accomplished. In contrast to the control soil, the grave soils were characterized by lower bulk density and pH. The degradation of the soil structure caused by digging led to a higher water table and the expansion of the reducing conditions in the graves where the prevalent absence of oxygen in range of the coffins inhibited decomposition processes. Although the formation of adipocere led to the conservation of the buried corpses, phosphorus, dissolved organic carbon, and cadavarine leaching from the graves was observed. Microbial biomass and microbial activity were higher in the control soil and hence reflected the inert character of adipocere. The study results clearly show the need for additional approaches in forensic, pedologic, and microbiologic research. PMID:15499507

    PubMed

    2005-01-01

    Community acquired pneumonia (CAP) is an acute respiratory infection that affects pulmonary parenchyma, and is caused by community acquired microorganisms. In Chile, pneumonia represents the main cause of death due to infectious diseases and is the third specific cause of mortality in adults. In 1999, an experts committee in representation of "Sociedad Chilena de Enfermedades Respiratorias", presented the first National Guidelines for the Treatment of Adult Community Acquired Pneumonia, mainly based in foreign experience and documents, and adapted it to our National Health System Organization. During the last decade, impressive epidemiological and technological changes have occurred, making the update of guidelines for treatment of NAC by several international scientific societies, necessary. These changes include: new respiratory pathogens that are being identified in CAP and affect adult patients (Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumophila); the increasing senescent adult population that carries multiple co-morbidities; the emergence of antimicrobial resistance among respiratory pathogens associated to massive antibiotic prescription; the development by the pharmaceutical industry of new drugs that are effective for pneumonia treatment (macrolides, ketolides and respiratory fluorquinolones); and the development of new diagnostic techniques for detection of antigens, antibodies, and bacterial DNA by molecular biology, useful in respiratory infections. Based on these antecedents, an Advisory Committee of "Sociedad Chilena de Enfermedades Respiratorias" and "Sociedad Chilena de Infectología" has reviewed the national and international evidence about CAP management in adults in order to update clinical recommendations for our country.

    2008-01-01

    The Natufians of the southern Levant (15,000–11,500 cal BP) underwent pronounced socioeconomic changes associated with the onset of sedentism and the shift from a foraging to farming lifestyle. Excavations at the 12,000-year-old Natufian cave site, Hilazon Tachtit (Israel), have revealed a grave that provides a rare opportunity to investigate the ideological shifts that must have accompanied these socioeconomic changes. The grave was constructed and specifically arranged for a petite, elderly, and disabled woman, who was accompanied by exceptional grave offerings. The grave goods comprised 50 complete tortoise shells and select body-parts of a wild boar, an eagle, a cow, a leopard, and two martens, as well as a complete human foot. The interment rituals and the method used to construct and seal the grave suggest that this is the burial of a shaman, one of the earliest known from the archaeological record. Several attributes of this burial later become central in the spiritual arena of human cultures worldwide. PMID:18981412

    2003-01-01

    A study was performed at the University of Florida to measure ground penetrating radar(GPR) performance for detecting forensic burials. In controlled scenarios, 24 burials were constructed with pig cadavers. Two soils were utilized to represent two of the most common soil orders in Florida: an Entisol and an Ultisol. Graves were monitored on a monthly basis for time periods up to 21 months with grid data acquired with pulsed and swept-frequency GPR systems incorporating several different frequency antennas. A small subset of the graves was excavated to assess decomposition and relate to the GPR images during the test. The grave anomalies in the GPR depth profiles became less distinctive over time due to body decomposition and settling of the disturbed soil (backfill) as it compacted. Soil type was a major factor. Grave anomalies became more difficult to recognize over time for deep targets that were within clay. Forensic targets that were in sandy soil were recognized for the duration of this study. Time elapsed imagery will be presented to elucidate the changes, or lack thereof, of grave anomalies over the duration of this study. Further analysis was performed using Synthetic Aperture Radar (SAR) reconstruction of images in 2-D and 3-D.

    1991-11-01

    To investigate the relationships between lymphocyte subsets and thyroid function, peripheral blood lymphocytes were analysed with cell surface antigens of activated (HLA-DR+) T, helper T (CD4+ 2H4-, CD4+ 4B4+) and suppressor-inducer T (CD4+ 2H4+, CD4+ 4B4-) cells subsets in 56 patients with Graves' disease, 16 patients with Hashimoto's thyroiditis, 7 patients with typical subacute thyroiditis and 2 patients with the thyrotoxic phase of autoimmune thyroiditis. Both patients with Graves' disease and Hashimoto's thyroiditis had increased percentages of HLA-DR+ T (Ia+ CD3+) cells as well as HLA-DR+ helper-inducer T (Ia+ CD4+) cells, which seemed to be independent of treatments. The percentage of HLA-DR+ suppressor-cytotoxic T (Ia+ CD8+) cells was increased in euthyroid or hypothyroid patients with Graves' disease following treatment, but was normal in hyperthyroid patients. The percentages of Ia+ CD4+ cells and Ia+ CD8+ were also increased in patients with thyroiditis, whereas these abnormal values normalized in the remission phase. These findings suggest that an increase in Ia+ CD4+ cells characteristically occurs during immune system activation in patients with hyperthyroid Graves' disease, Hashimoto's thyroiditis and the thyrotoxic phase of subacute thyroiditis, whereas the activated CD8+ cells in Graves' disease are induced by antithyroidal therapy.

  18. A tale of two celts.

    PubMed

    Wheeler, Malcolm H

    2010-06-01

    The eponym "Graves' disease" is usually applied to the condition of immunogenic hyperthyroidism, in no small part due to the promotion and influence of the French physician Armand Trousseau who wrote in 1862, "Du Goître Exophthalmique, ou Maladie de Graves." However, the distinguished Bath physician Caleb Hillier Parry, a friend of both Edward Jenner and John Hunter, first described the clinical picture of thyrotoxicosis associated with exophthalmos and cardiac dysfunction in a paper published posthumously in 1825, some 10 years before Robert Graves' initial report. Graves was unaware of Parry's earlier description and considered that the thyroid condition in the four female cases that he studied might be secondary to functional cardiac disorders and palpitations. The many outstanding contributions to medicine and science of Parry and Graves, two truly remarkable nineteenth century Celtic physicians, are compared and discussed. A case is made for considering the renaming of immunogenic hyperthyroidism as Parry's disease, a proposal made by Sir William Osler, who was the first to recognise Parry's claim for priority for the recognition of exophthalmic goitre.

    2015-01-01

    A 29-year-old pregnant woman with Graves' disease presented with severe persistent hypocalcaemia after thyroidectomy. Six months prior to presentation she was diagnosed with Graves' disease and remained uncontrolled with methimazole. She was confirmed pregnant prior to radioactive iodine ablation (RAI), and underwent total thyroidectomy during her second trimester. After surgery, continuous intravenous calcium infusion was required until delivery of the fetus allowed discontinuation at postoperative day 18, despite oral calcium and calcitriol administration. A total of 38 g of oral and 7.5 g of intravenous elemental calcium was administered. We report an unusual case of recalcitrant hypocalcaemia thought to be due to a combination of postoperative hypoparathyroidism, combined with thyrotoxic osteodystrophy and pregnancy, after surgical correction of Graves' disease. Increased vigilance and early calcium supplementation should be a priority in the management of these patients. PMID:25969482

    Inorganic pyrophosphatase (PPase) controls the level of inorganic pyrophosphate produced by biosynthesis of protein, RNA, and DNA. Thus, PPase is essential for life. PPase expression is unclear in the thyroid. We cloned a new human PPase, phospholysine phosphohistidine inorganic pyrophosphate phosphatase (LHPPase), and established a rabbit polyclonal anti-LHPPase antibody. This is First study to determine the PPase expression by immunohistochemistry and Western blot. Intranuclear LHPPase expression of thyrocytes was enhanced most prominently in Graves' disease and autonomously functional thyroid nodule. To estimate a regulating factor of subcellular localization of LHPPase, we examined its expression of Graves' disease-derived thyrocytes in vitro with the disease-originated serum. Nuclear expression of LHPPase was lost in cultured thyrocytes even with the serum, while its cytoplasmic expression was retained. The data suggest that increased expression of LHPPase is associated with hyperthyroidism. Intranuclear expression of LHPPase may not be regulated by Graves' disease-derived serum factors.

  1. Ancient DNA reveals kinship burial patterns of a pre-Columbian Andean community

    PubMed Central

    2012-01-01

    Background A detailed genetic study of the pre-Columbian population inhabiting the Tompullo 2 archaeological site (department Arequipa, Peru) was undertaken to resolve the kin relationships between individuals buried in six different chullpas. Kin relationships were an important factor shaping the social organization in the pre-Columbian Andean communities, centering on the ayllu, a group of relatives that shared a common land and responsibilities. The aim of this study was to evaluate whether this Andean model of a social organization had an influence on mortuary practices, in particular to determine whether chullpas served as family graves. Results The remains of forty-one individuals were analyzed with both uniparental (mtDNA, Y–chromosome) and biparental (autosomal microsatellites) markers. Reproducible HVRI sequences, autosomal and Y chromosomal STR profiles were obtained for 24, 16 and 11 individuals, respectively. Mitochondrial DNA diversity was comparable to that of ancient and contemporary Andean populations. The Tompullo 2 population exhibited the closest relationship with the modern population from the same region. A kinship analysis revealed complex pattern of relations within and between the graves. However mean relatedness coefficients regarding the pairs of individuals buried in the same grave were significantly higher than those regarding pairs buried in different graves. The Y chromosome profiles of 11 males suggest that only members of one male line were buried in the same grave. Conclusions Genetic investigation of the population that inhabited Tompullo 2 site shows continuity between pre-Columbian and modern Native Amerindian populations inhabiting the Arequipa region. This suggests that no major demographic processes have influenced the mitochondrial DNA diversity of these populations during the past five hundred years. The kinship analysis involving uni- and biparental markers suggests that the community that inhabited the Tompullo 2 site

    1990-01-01

    A program for mission planning called the Analytic Satellite Ephemeris Program (ASEP), produces projected data for orbits that remain fairly close to the Earth. ASEP does not take into account lunar and solar perturbations. These perturbations are accounted for in another program called GRAVE, which incorporates more flexible means of input for initial data, provides additional kinds of output information, and makes use of structural programming techniques to make the program more understandable and reliable. GRAVE was revised, and a new program called ORBIT was developed. It is divided into three major phases: initialization, integration, and output. Results of the program development are presented.

    The invention provides a light weight analyzer, e.g., detector, capable of locating clandestine graves. The detector utilizes the very specific and unique chemicals identified in the database of human decompositional odor. This detector, based on specific chemical compounds found relevant to human decomposition, is the next step forward in clandestine grave detection and will take the guess-work out of current methods using canines and ground-penetrating radar, which have historically been unreliable. The detector is self contained, portable and built for field use. Both visual and auditory cues are provided to the operator.

  4. Assessing the potential risks of burial practices on groundwater quality in rural north-central Nigeria.

    PubMed

    Zume, Joseph T

    2011-09-01

    Several cultures of north-central Nigeria do not use community cemeteries. Instead, human remains are buried in and around family compounds, often in shallow and sometimes unmarked graves. At several locations, graves and drinking water wells end up too close to be presumed environmentally safe. This paper reports findings of a pilot study that explored the potential for groundwater contamination from gravesites in some rural settlements of north-central Nigeria. Preliminary results suggest that the long-standing burial practices among some cultures of rural north-central Nigeria may potentially compromise groundwater quality, which is, by far, their most important source of drinking water.

    2016-07-01

    Amiodarone-induced thyrotoxicosis (AIT) type I describes inducement of clinical hyperthyroidism by excessive thyroidal iodine in the setting of latent Graves disease, and therapy differs from that used for AIT type II. A 65-year-old man previously on amiodarone for atrial fibrillation developed clinical hyperthyroidism. Diagnosis of AIT was made, but the type was not clear. Tc sestamibi thyroid scan showed diffusely increased uptake and retention in an enlarged thyroid gland, a pattern consistent with AIT type I. Methimazole was initiated and controlled the thyrotoxicosis. I iodide thyroid scan and uptake study performed later was consistent with Graves disease. PMID:27163459

    A coagglutination technique was established for the detection of lipoarabinomannan of Mycobacterium tuberculosis in human serum samples and evaluated for its utility in the diagnosis of tuberculosis at the Instituto Nacional de Enfermedades Respiratorias in Mexico City. The test had a sensitivity of 88% in patients with sputum-smear-positive active pulmonary tuberculosis. The sensitivity in patients with active pulmonary tuberculosis negative for acid-fast bacilli in sputum was 67%. Less favorable results were obtained for patients with AIDS and tuberculosis, with a sensitivity of 57%. The specificity in control patients with lung diseases different from tuberculosis and in healthy subjects was 100%. The positive predictive value was 100%, and the negative predictive value for patients with sputum-positive active pulmonary tuberculosis was 97%. The results of this study suggest that the detection of lipoarabinomannan is an accurate test for the diagnosis of pulmonary tuberculosis. PMID:1401008

  9. Study plan for conducting a section 316(a) demonstration: K-Reactor cooling tower, Savannah River Site

    SciTech Connect

    Paller, M.H.

    1991-02-01

    The K Reactor at the Savannah River Site (SRS) began operation in 1954. The K-Reactor pumped secondary cooling water from the Savannah River and discharged directly to the Indian Grave Branch, a tributary of Pen Branch which flows to the Savannah River. During earlier operations, the temperature and discharge rates of cooling water from the K-reactor were up to approximately 70{degree}C and 400 cfs, substantially altering the thermal and flow regimes of this stream. These discharges resulted in adverse impacts to the receiving stream and wetlands along the receiving stream. As a component of a Consent Order (84-4-W as amended) with the South Carolina Department of Health and Environmental Control, the Department of Energy (DOE) evaluated the alternatives for cooling thermal effluents from K Reactor and concluded that a natural draft recirculating cooling tower should be constructed. The cooling tower will mitigate thermal and flow factors that resulted in the previous impacts to the Indian Grave/Pen Branch ecosystem. The purpose of the proposed biological monitoring program is to provide information that will support a Section 316(a) Demonstration for Indian Grave Branch and Pen Branch when K-Reactor is operated with the recirculating cooling tower. The data will be used to determine that Indian Grave Branch and Pen Branch support Balanced Indigenous Communities when K-Reactor is operated with a recirculating cooling tower. 4 refs., 1 fig. 1 tab.
