Tonsillectomy adenoidectomy and adenotonsillectomy - post operative complications. A meta-Analysis

Introduction: Tonsillectomy and adenoidectomy is a relatively safe procedure and is one of the most common operations performed by otolaryngologists, but it is nevertheless associated with certain complications.AIM: The aim of the present study was to summarize the data about complications after tonsillectomy with or without adenoidectomy.Matherial and methods : A meta-analysis was performed, comprising publications on tonsillectomy and adenoidectomy retrieved from the Medline bibliographic database. We show are results and compare with published articles.Results: The average rate of postoperative complications in the reviewed publications is 7.48% with range from 1, 37% to 14,96%.Discussion: The postoperative period is with a low risk of complications. The results from published articles and our clinic showed that the larger share occupy major complications - 1854/93.63% in the Medline bibliographic database and 23/52.27% - our result. The complications after tonsillectomy with/without adenoidectomy are rare, but for the most part - major, which necessitates caution in the postoperative period.Conclusion: In conclusion we can say that tonsillectomy is one of the most commonly practiced operations with rare rate of complications, which anyway requires knowledge for recognizing

Лапароскопическая холецистэктомия у больных, ранее перенесших оперативные вмешательства на органах брюшной полости

Авторами приводится опыт выполнения лапароскопической холецистэктомии 910 больным, ранее перенесшим оперативные вмешательства на органах брюшной полости, из них, 85 больным выполнен адгезиолизис. Проведен анализ эффективности дооперационной диагностики и лапароскопических методов коррекции спаечной болезни. По мнению авторов, сонография обладает высокой диагностической ценностью при спаечной болезни и позволяет выбрать наиболее безопасную точку введения первого троакара, наиболее эффективным и безопасным методом адгезиолизиса является использование для рассечения спаек ультразвукового скальпеля. Авторами наводиться досвід виконання лапароскопічної холецистектомії 910 хворим, які раніше перенесли оперативні втручання на органах черевної порожнини, з них 85 хворим виконано адгезіолізис. Проведений аналіз ефективності доопераційної діагностики та лапароскопічних методів корекції злуково хвороби. На думку авторів, сонографія має високу діагностичну цінність при злуковій хворобі та дозволяє вибрати найбільш безпечне місце введення першого троакару, найбільш ефективним та безпечним методом адгезіолізису є використання для розсічення спайок ультразвукового скальпеля. Authors are bring experience of execution of laparoscopic cholecystectomy at 910 patients, endured operations on the organs of abdominal cavity in past, of them, at 85 of patients it was executed adheziolysis. The analysis of efficiency of the preoperative diagnostics and laparoscopic methods of correction of soldering disease is conducted. In opinion of authors sonography possesses a high diagnostic value at soldering disease and allows to choose the most safe point of introduction of the first troacar, the most effective and safe method of adhesiolysis is the use of ultrasonic scalpel for the section of joints

Heminephrectomy in adults: a systematic review with cumulative analysis

Introduction: Duplex collecting system of the kidney is a relatively common abnormality, with the majority of symptomatic cases discovered in childhood. Treatment is commonly a heminephrectomy of the affected moiety. We aimed to conduct a systematic review of the literature to provide the best available evidence for heminephrectomy for duplex kidneys in the adult population. Materials and Methods: A literature search was conducted in September 2017 with no limitations being placed on language, region, date or publication type. Data were represented numerically and analysed cumulatively. Results: Seven retrospective studies with 66 patients were included. Of which, 56/66 operations were performed laparoscopically, 5/66 were robot-assisted and 5/66 were open procedures. Complete resolution of symptoms was reported in 53/55 (96.4%) of patients in five studies providing outcome data. Of the 6 studies reporting complications, there were a total of 9 complications (9/62, 14.5%), however 5 of these were found to be in one study alone. Conclusions: This review emphasises the scarcity of evidence for heminephrectomy in adults. Nonetheless, it has been shown that this operation may be effective in alleviating patients’ symptoms in addition to being safe in experienced hands

A theorem prover-based analysis tool for object-oriented databases

We present a theorem-prover based analysis tool for object-oriented database systems with integrity constraints. Object-oriented database specifications are mapped to higher-order logic (HOL). This allows us to reason about the semantics of database operations using a mechanical theorem prover such as Isabelle or PVS. The tool can be used to verify various semantics requirements of the schema (such as transaction safety, compensation, and commutativity) to support the advanced transaction models used in workflow and cooperative work. We give an example of method safety analysis for the generic structure editing operations of a cooperative authoring system

Formation of safety conditions for development of deposits by open mining

The researched parameters of the catching device, which ensures the safe operation of equipment and working people in deep open pits, where are formed the benches by steep dipping layers. For obtaining the results, the following methods were used: analytical – in determining existing devices for the capture of rocks; geometric – in determining the direction of the flight of blocks, semigraphical – in plotting and analyzing them. The modern technological catching devices, their structure, construction are analyzed. These structures protective devices can be used in deep pits in the development of deposits. Analytical dependence of the height of the jump the block of rock after hitting about a horizontal surface is improved, which takes into account the rate of falling and the angle of rebound the block, the elasticity of the surface. Creating of catching designs which capture the blocks of rock in the falling from the upper horizons in open pits allows to operate safely the mining equipment and to save the lives of workers. Especially this is important in the development of deposits by steep dipping layers. Proposed solutions can improve the safe using of dump trucks and moving workers in the work zone in the mining ledges of height over 30 meters

A renormalization fixed point for Lorenz maps

A Lorenz map is a Poincar\'e map for a three-dimensional Lorenz flow. We describe the theory of renormalization for Lorenz maps with a critical point and prove that a restriction of the renormalization operator acting on such maps has a hyperbolic fixed point. The proof is computer assisted and we include a detailed exposition on how to make rigorous estimates using a computer as well as the implementation of the estimates.Comment: 29 pages, 2 figure
