Introduction: The aim of this study was to assess the epidemiological aspect and the difficulties associated with the surgical management of hyperthyroidism in our context. Hyperthyroidism is an over function of the thyroid gland resulting in thyrotoxicosis. Thyroidectomy is one of the Main treatments. It also uses synthetic antithyroid drugs, radioactive iodine. Methodology: We carried out a descriptive 6-year retrospective from January 1, 2011 to December 31, 2017 inclusively. Our study variables were qualitative and quantitative, Results: During our study, 26 cases were collected between January 2011 and August 2017 with a predominance of 73% female and an average age of 52, 78 years. The clinic was dominated by the signs of thyrotoxicosis which were found in all patients. The exploration identified 14 cases of toxic multi-hetero nodular goiter, ie 53.84%; 9 cases of basal disease 34, 66% and 3 cases of toxic adenoma 11, 54%. Medical preparation was required in all our patients Total thyroidectomy was performed in one patient, i.e. 4%, and Lobo isthmectomy in 24 patients, ie 96%. Postoperatively, complications were collected: 1 case of intraoperative hemorrhage 20%; 1 case of postoperative hematoma 20%; 1 case of dysphonia 20%. Conclusion: Surgery for toxic goiter known to be hemorrhagic and adherent should be performed after obtaining euthyroidism and double vigilance to minimize the morbidity represented mainly by laryngeal paralysis and hyperparathyroidism

Toxic Goiter

Graves' disease (GD) is the most common cause of juvenile thyrotoxicosis in children and adolescents (1, 2). Three treatment modalities are now available for the treatment of Graves' thyrotoxicosis in childhood: antithyroid drugs (ATD), surgery and radioactive iodine (RAI). However, none of these treatments has been shown to be ideal or clearly superior to the others. Physicians in different countries have different approaches concerning the optimal treatment of juvenile GD.In a European questionnaire study (3), which was conducted by the European Thyroid Association in 1993 and in which 99 individuals or groups from 22 countries participated, it was found that 22 out of 99 physicians from nine countries would consider RAI treatment as the treatment of choice for children with recurrent thyrotoxicosis after surgery, or with recurrent thyrotoxicosis 2 years after ATD. However, RAI is preferred by only a small percentage of physicians for this group of patients in Europe. Hardly any of the respondents chose RAI for the patients with a toxic adenoma or a multinodular toxic goiter (3). On the other hand, in view of the difficulties with medical therapy in children and adolescents, including poor compliance, a high rate of relapse, drug toxicity and continued thyroid enlargement, some eminent American physicians emphasize the safety, simplicity and economic advantages of (131)I ablation which should be considered more commonly in children (4, 5).We had the opportunity to conduct a similar study during a pediatric thyroidology symposium, which was organized by Professors Buyugkebiz and Laron in Izmir (Smyrna) Turkey from 30 October to 1 November 2003. During the congress a questionnaire with the following four questions was circulated among the 120 participants from eight countries who were mainly paediatric endocrinologists. Most of them were from Turkey and the rest, except for one who came from the USA, were Europeans. Sixty-one out of the 120 physicians responded.

The COVID-19 outbreak has created an unprecedented challenge for governments to convey information to the public, and social media has become a critical method of COVID-19 communication in Taiwan. Objectives: This study examines a total of 1128 Facebook posts published by Taiwan’s principal health authority from December 1, 2019 to May 31, 2020. Methods: Using both qualitative and quantitative approaches, this study investigates strategies used by the Taiwan government to communicate the COVID-19 outbreak and public responses toward these strategies. Result: Novel uses of Facebook posts on outbreak communication were identified, including solidarity, reviews of actions, press conferences, and the use of animal and cartoon images. Quantitative results showed that the public responded significantly more frequently to messages generating positive affects, such as posts that reviewed government actions and public efforts; posts that expressed thanks, approval, or comradeship; and posts that paired text with photographs of frontline workers or cute animals. Conclusion: These results suggest that, amid a disease outbreak, the public not only look for updated situations and guidelines but also for affective affirmation from government agencies.

The use of anthropomorphic test devices (ATDs) for calculating injury risk of occupants in spaceflight scenarios is crucial for ensuring the safety of crewmembers. Finite element (FE) modeling of ATDs reduces cost and time in the design process. The objective of this study was to validate a Hybrid III ATD FE model using a multidirection test matrix for future spaceflight configurations. Twenty-five Hybrid III physical tests were simulated using a 50th percentile male Hybrid III FE model. The sled acceleration pulses were approximately half-sine shaped, and can be described as a combination of peak acceleration and time to reach peak (rise time). The range of peak accelerations was 10–20 G, and the rise times were 30–110 ms. Test directions were frontal (−GX), rear (GX), vertical (GZ), and lateral (GY). Simulation responses were compared to physical tests using the correlation and analysis (CORA) method. Correlations were very good to excellent and the order of best average response by direction was −GX (0.916±0.054), GZ (0.841±0.117), GX (0.792±0.145), and finally GY (0.775±0.078). Qualitative and quantitative results demonstrated the model replicated the physical ATD well and can be used for future spaceflight configuration modeling and simulation.

<p><strong>Objective:</strong> The modified fixed doses of radioactive iodine (RAI) in different types of hyperthyroidism had been practiced at National Institute of Nuclear Medicine &amp; Allied Science (NINMAS) according to Society of Nuclear Medicine Bangladesh (SNMB) protocol since 2002 which was upgraded in 2015. The objective of the study was to observe the treatment outcome in modified fixed dose on previous protocol. Patients and Methods: In the present study the outcome of radioiodine therapy of hyperthyroid patients was retrospectively evaluated in 1349 consecutive primary hyperthyroid patients treated from January 2010 to December 2014 at NINMAS. Diagnosis of hyperthyroidism was done by thyroid function test; thyroid stimulating hormone (TSH), free triiodothyronine (FT3)   &amp; free thyroxine (FT4), 99m Technetium scan, thyroid radioiodine uptake and ultrasound imaging of thyroid gland. All patients received a fixed dose (8-29 m Ci) of radioactive iodine (RAI) depending on types of hyperthyroidism, visual assessment of gland size and severity of disease at diagnosis. They were followed up at 2 months of therapy, then every three months intervals for first year and thereafter 6 monthly up to 5 years or as needed during fluctuation of thyroid function.</p><p><strong>Results:</strong> Among the study population, 832 patients had diffuse toxic goiter (Graves’ disease), 369 patients were diagnosed as toxic multinodular goiter and 148 patients with single toxic nodule. At one year follow-up, permanent hypothyroidism occurred in 61.62% of patients and the cumulative incidence of hypothyroidism progressively increased up to 79.25% after 5 years. Cure or success of RAI therapy was considered as attainment of euthyroid state or hypothyroid state. About 11.26 % patients received more than single dose.</p><p><strong>Conclusion:</strong> Fixed dose RAI therapy is very much cost effective mode of treatment for primary hyperthyroidism with ~89% success by giving single dose.</p><p>Bangladesh J.

Poor Lighting

Image enhancement is a critical process in imagebased systems. In these systems, image quality is a crucial factor to achieve a good performance. Scenes with a dynamic range above the capability of the camera or poor lighting are challenging conditions, which usually result in low contrast images, and, with that, we can have the underexposure and/or overexposure problem. In this work, our aim is to restore illexposed images. For this purpose, we present UCAN, a small and fast learning-based model capable to restore and enhance poorly exposed images. The obtained results are evaluated using image quality indicators which show that the proposed network is able to improve images damaged by real and simulated exposure. Qualitative and quantitative results show that the proposed model outperforms the existing models for this objective.
