Single Site Surgery

Laparo-Endoscopic Single-Site surgery (LESS) for kidney diseases is quickly evolving and has a tendency to expand the urological armory of surgical techniques. However, we should not be overwhelmed by the surgical skills only and weight it against the basic clinical and oncological principles when compared to standard laparoscopy. The initial goal is to define the ideal candidates and ideal centers for LESS in the future. Modification of basic instruments in laparoscopy presumably cannot result in better functional and oncological outcomes, especially when the optimal working space is limited with the same arm movements. Single port surgery is considered minimally invasive laparoscopy; on the other hand, when using additional ports, it is no more single port, but hybrid traditional laparoscopy. Whether LESS is a superior or equally technique compared to traditional laparoscopy has to be proven by future prospective randomized trials.

Проблема понимания текстов и способов его оценки является одной из фундаментальных для современной психологии, педагогики, лингвистики. На настоящий момент имеется большое количество попыток выработки метода оценки понимания текстов, который бы отражал объективную картину интериоризации материала текста читателем, и вместе с тем подходил бы для стандартизации и применения на широком диапазоне текстов различного содержания и структуры, по возможности с минимальными затратами ресурсов оценщика и самого читателя. В настоящей статье раскрываются современные подходы к оценке понимания текстов, их преимущества и недостатки, и формулируется новый перспективный метод оценки понимания текстов, использующий в своём основании модель Латентного размещения Дирихле. Данный метод затем проходит исследование валидности через сравнение результатов его применения и наиболее часто используемых современных методов оценки понимания текстов, делается вывод о его применимости в реальных условиях и перспективах использования в спектре прикладных задач. The problem of understanding texts and methods of assessing it is one of the fundamental for modern psychology, pedagogy, linguistics. At the moment, there are a large number of attempts to develop a method for assessing the understanding of texts, which would reflect an objective picture of the internalization of the material of the text by the reader, and at the same time would be suitable for standardization and application on a wide range of texts of different content and structure, if possible with minimal expenditure of resources of the evaluator and the reader himself. This article reveals modern approaches to assessing text understanding, their advantages and disadvantages, and formulates a new promising method for assessing text understanding, based on the Dirichlet Latent Placement model. This method then goes through a validity study through a comparison of the results of its application and the most commonly used modern methods for assessing text understanding, a conclusion is made about its applicability in real conditions and the prospects for use in a range of applied problems.

Irrigação de pastagens via pivô central, na bovinocultura de corte.  Leonardo Pretto de Azevedo1; João Carlos Cury Saad21 Instituto Federal de São Roque, São Roque, SP, [email protected] de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP,   1 RESUMO          O presente trabalho teve como objetivo apresentar o sistema de irrigação de pastagens via pivô central na bovinocultura de corte brasileira, bem como discutir a viabilidade econômica desta prática em diferentes regiões do país. Foram apresentados fatores importantes na produção de massa seca de forrageiras tropicais, como temperatura, radiação solar, adubação e água. Também foram apresentadas as vantagens e desvantagens do sistema, bem como uma breve discussão de sua viabilidade econômica. Concluiu-se que a irrigação de pastagens pode ser uma técnica economicamente viável para regiões específicas do Brasil, considerando-se os fatores envolvidos e esclarecendo que apenas o fornecimento de água às culturas não resolve o problema da estacionalidade durante o inverno. UNITERMOS: pivô central, forrageiras, viabilidade econômica  AZEVEDO, L. P.; SAAD, J. C. C. Pasture irrigation under center pivot for beef cattle.  2 ABSTRACT          The aims of this work were to show the pasture irrigation system by center pivot with Brazilian cattle and to discuss the economic feasibility of this technique in different regions of the country. Important parameters to dry matter production of tropical forage plants, as temperature, solar radiation, fertilization, and water requirement were shown Also, the system advantages and disadvantages and a discussion about economic feasibility of this technique were presented. It was concluded that pasture irrigation is a feasible and economical technique to some specific Brazilian regions, depending on appropriated parameters. This work also concludes that just water supply is not enough to assure forage production avoiding reduction in dry production in the winter. KEYWORDS: center pivot, pasture, economic feasibility

Traumatic atlantoaxial instability usually results from a motor vehicle accident, falls and motorcycle accidents. Atlantoaxial instability can lead to spinal cord compression and neck pain, but, spasticity and radicular symptoms as well. The purpose of surgery is to remove the compression and stabilize the joint permanently. To date, several surgical techniques have been described to remedy C1-C2 instability. In this study, the clinical and radiological outcomes of patients who operated with the C1 (Atlas bone) laminar hooks fixation and bilateral C2 (Axis bone) trans-pedicular screw technique were shown. Also, the advantages and disadvantages of this technique are discussed. From March 2010 to December 2017, 12 patients who have atlantoaxial instability were surgically treated by modified fixation technique which consists C1 laminar hooks fixation and bilateral C2 transpedicular screw. Twelve patients were operated with this procedure from March 2010 to December 2017. All the patients were checked with flexion-extension x-rays at the end of the twelfth week. The posterior bony fusion formation was observed on imaging in all patients. C2 bilateral pedicle screw combined with C1 laminar hook system is a good method for atlantoaxial instability in the conditions which is not convenient for insertion of C1 lateral mass and C2 trans-articular screw. However, this method may not be available in some cases such as traumatic, infection, neoplastic or degenerative pathologies in which the posterior arch of the atlas is damaged.

Nasal Augmentation

Multiple techniques have been described for dorsal nasal augmentation in rhinoplasty. In this article, we review common surgical techniques for raising the dorsum or eliminating dorsal irregularities, by highlighting inherent advantages and disadvantages of each method. Within the past few years, the use of diced cartilage grafts has become the workhorse in this field of interest. To overcome drawbacks of methods based on diced cartilage, we present a new concept for autologous augmentation, using regenerative medicine protocols. A mix of cartilage scales with cartilage pâté was embedded in platelet-rich fibrin (PRF). Since December 2015, a total of 48 patients were treated with this technique. Based on our preliminary results, cartilage scales in PRF appear to be a promising and reliable alternative to existing procedures for dorsal nasal augmentation.

Cesarean delivery is one of the most frequently performed surgeries in women throughout the world. However, the most optimal technique to minimize maternal and fetal morbidities is still being debated due to various clinical situations and surgeons’ preferences. The contentious topics are the use of vacuum devices other than traditional fundal pressure to assist in the delivery of the fetal head and the techniques of uterine repair used during cesarean deliveries. There are two well-described techniques for suturing the uterus: The uterus can be repaired either temporarily exteriorized (out of abdominal cavity) or in situ (within the peritoneal cavity). Numerous studies have attempted to compare these two techniques in different aspects, including operative time, blood loss, and maternal and fetal outcomes. This review provides an overview of the assistive method of vacuum devices compared with fundal pressure, and the two surgical techniques for uterine repair following cesarean delivery. This descriptive literature review was performed to address important issues for clinical practitioners. It aims to compare the advantages and disadvantages of the assistive methods and surgical techniques used in cesarean deliveries. All of the articles were retrieved from the databases Medline and PubMed using the search terms cesarean delivery, vacuum, and exteriorization. The searching results revealed that after exclusion, there were 9 and 13 eligible articles for vacuum assisted cesarean delivery and uterine exteriorization, respectively. Although several studies have concluded vacuum assistance for fetal extraction as a simple, effective, and beneficial method during fetal head delivery during cesarean delivery, further research is still required to clarify the safety of vacuum assistance. In general, compared to the use of in situ uterine repairs during cesarean delivery, uterine exteriorization for repairs may have benefits of less blood loss and shorter operative time. However, it may also carry a higher risk of intraoperative complications such as nausea and vomiting, uterine atony, and a longer time to the return of bowel function. Clinicians should consider these factors during shared decision-making with their pregnant patients to determine the most suitable techniques for cesarean deliveries.
