Objectives: To study the clinical and therapeutic profiles of voluminous goiter. Patients and Methods: We carried out a descriptive and prospective study, relating to a series of 30 cases of voluminous goitre, collected in the Department of Otorhinolaryngology and cervicofacial surgery (ENT and CCF) of the CHU Luxembourg Mother Child of Bamako. It has been spread over a period of 4 years from January 2015 to December 2018. Patients of all ages operated for large goitre at the ENT Department of CHU Luxembourg Mother Enfant were included. Results: In 4 years we collected 30 cases of voluminous goitre;during this period we realized 180 thyroidectomies, i.e. frequency of 16.67%. The average age was 51.37 years with an extreme ranging from 38 to 65 years. Females were common in 66.7% with a sex ratio of 0.50. The long duration of evolution has been 40 years. The sign of compression was found in 85.7%. The physical examination found a mobile swelling, hard and painless in all patients with normal endolaryngeal examination;there was no cervical lymphadenopathy. The lower dipping pole was found in 5 cases on CT. All our patients were euthyroid. The classification of TIRADS 2 was found in 80.0% of cases. Total thyroidectomy was frequent with 50.0% of cases. The average weight of the operative specimen was 586.67 g with extremes ranging from 500 g to 800 g. The size of the operative piece of 14 cm was the longest. Injury of internal jugular vein was found in 26.7% of cases. Colloid adenoma of the thyroid was found in 100% of cases, postoperative complications of the type of hematoma of the lodge in 3.3% of cases, the release of the operative wound in 10% of cases local superinfection in 7.1%. Signs of hypothyroidism were common with 50.0%. Postoperative nasofibroscopy found good vocal fold mobility in all patients. Conclusion: The large goiters have become rare because of the early management of thyroid nodule. Its management must allow the prevention of recurrent and parathy

Tonsillitis or angina, is considered as an inflammation of the palatine tonsils most often of infectious origin. It can be acute or chronic. The germs in question are mostly viruses and bacteria. Objectives: The objective of this work was to study the epidemiological and therapeutic profile of tonsillitis and their complications in the ENT Department and Head and Neck Surgery of the Mother-Child University Hospital in Luxembourg. Patients and Methods: This is a prospective study over a 12-month period from January 2018 to December 2018, including all patients who presented with tonsillitis and/or their complications. Results: Three hundred and fifteen (315) patients were collected during this period. The average age in our study was 14.25 years with extremes ranging from 2 years to 61 years. The sex ratio was 0.65 in favor of the female sex. During this period we recorded 80.95% of cases of uncomplicated tonsillitis including 60.50% for acute tonsillitis, 24.5% for chronic tonsillitis 5% for adenoid tonsillitis and 19.05% for complications. Complications included peritonsillar phlegmon 42.22%, heart disease 33.33%, cervical cellulitis 8.89%, adeno-phlegmon 6.67%, para-pharyngeal abscess 4.44%, and sepsis 4.44%. The exclusive medical treatment was performed in 44.31%. Surgical treatment (drainage incision and tonsillectomy) was performed in 55.69%. Conclusion: Tonsillitis and its complications represent an important pathology in ENT. Feynophagy febrile is the pair-origin symptom that can lead to the diagnosis. The prevention of complications is the guarantor of the reduction of its morbidity. We recommend that in the absence of RDT (Rapid Diagnostic Test), it is necessary to systematize antibiotic therapy to prevent serious complications.

Introduction: Cervical cystic lymphangiomas are rare benign dysembryoplastic tumors of lymphatic origin. Its severity in the child is due on one hand to their fast evolution and the compression of the way aerodigestive and on the other hand, by the classical difficulty of their excision. The purpose of this work was to report a case of giant cervical cystic lymphangioma in a child to discuss the difficulties associated with its management in our context. Observation: This was a 3-year-old female child who was admitted to the ENT department of CHU “Luxembourg” for right lateral cervical swelling. The clinical examination had noted a large anterior-latero cervical swelling of soft, renitent, painless palpation, movable in relation to the superficial and deep plane, measuring about 20 cm × 17 cm, the skin was healthy. It wasn’t particularity to the rest of the physical examination. The diagnosis of giant cervical cystic lymphangioma was discussed. Thorough excision of the swelling by right lateral cervicotomy was performed. Anatomopathological examination of the operative specimen confirmed the diagnosis. The postoperative course was simple and the evolution was favorable. Conclusion: Cervical cystic lymphangiomas are rare. Their management involves surgery, with short and long-term post-operative outcomes are often excellent.

Introduction: Neonatal mortality remains a major public health concern. According to the World Health Organisation (WHO), the number of newborns dying each year has fallen from 5 million in 1990 to 2.4 million in 2019. The aim of our study was to describe the main morbid conditions and their lethality in newborns admitted to the paediatric ward of the CSREF in Commune V. Methodology: We conducted a 12-month prospective descriptive and analytical study from August 2020 to July 2021. Results: During the 12 months of the study, out of 2654 neonates admitted to hospital, 216 met our inclusion criteria, i.e. 8%. Newborns admitted in the first few hours of life represented 99.54% of cases. Full-term newborns accounted for 65.74% of the total. Forty-eight percent of newborns had hypothermia on admission. The most common diagnosis was asphyxia in 55.56% of cases, followed by neonatal infection in 27.78% and prematurity in 10.65%. Death was recorded in 22.2% of cases. Asphyxia was the main cause of neonatal death, followed by prematurity in our context. Conclusion: Improving the prognosis of newborn babies will require a thorough understanding of neonatal pathologies and the implementation of a pre- and perinatal prevention policy.

As computers have become faster at performing computations over the decades, algorithms to play games have also become more efficient. This research paper seeks to see how the performance of the Minimax search evolves on increasing Connect-4 grid sizes. The objective of this study is to evaluate the effectiveness of the Minimax search algorithm in making optimal moves under different circumstances and to understand how well the algorithm scales. To answer this question we tested and analyzed the algorithm several times on different grid sizes with a time limit to see its performance as the complexity increases, we also looked for the average search depth for each grid size. The obtained results show that despite larger grid sizes, the Minimax search algorithm stays relatively consistent in terms of performance.

本文采用二维数值模拟和室内试验相结合的方法研究了土石混合体裂缝的渐进剪切特性。采用颗粒流程序（PFC 2D）进行模拟。在PFC 2D中,以矩形盘的组合模拟断裂和完整试样。通过在PFC 2D中进行剪切试验模拟,得到了完整试样微观和宏观特性之间的相关性。为了定义断裂颗粒所对应的一组微观属性,并研究其对平面裂缝剪切行为的影响,对断裂模型微观属性进行了敏感性分析,包括颗粒摩擦系数、接触刚度和约束压力。室内剪切试验为直剪试验,对土石混合体完整和断裂试件进行了试验研究。根据土石混合体强度固结的影响因素,建立了相应的影响因素结构体系,基于摩尔-库伦准则建立了土石混合体抗剪强度表达式,并结合剪切破坏模型,描述了土石混合体基本的破坏形式。通过固结实验揭示了固结压力、固结时间这两个关键因素与土石混合体抗剪强度参数的关系,固结压力的增长引起土石混合体平均黏聚力呈二次函数规律增长,固结时间增长引起土石混合体黏聚力呈对数规律递减。土石混合体是一种具有岩土性质的地质材料。露天矿排土场由土石混合料组成。采用有限元法（Geo5 Finite Element method）和颗粒流离散元法（Particle flow code discrete Element method）对土石混合体边坡的稳定性进行了分析。在较硬的土石混合体中,随着固结压力的增加,黏聚力也随之增大。通过固结试验和直剪试验,确定了排土场的物理力学参数。根据PFC 2D对排土场堆积过程数值模拟的计算结果,得到了排土场的应力分布、位移和塑性区。采用强度折减法计算模型各分析步骤的安全系数（FOS）。采用极限平衡法进行排土场稳定性分析。分析结果表明,该排土场是稳定的。排土场潜在的破坏模式主要有组合滑动破坏模式,即上部为圆形滑动,下部为折线滑动,将土石层切入重度风化层。本文还介绍了矿用排土场设计分析的一些步骤和方法。为进一步优化排土场提供参考。该论文有图35幅,12表,参考文献111篇。
