Published: December 2019

The periodontal disease and gingival bleeding are highly prevalent in the adult population worldwide. The World Health Organization (WHO) data shows that 90–100% of the 34-year-old adults present gingival inflammation. Therefore, an investigation method is required to allow the assessment of the periodontal disease as well as the monitoring of the evolution of the gingival inflammation after periodontal treatments. Non-invasive and operator-independent methods for periodontal examination are necessary for diagnosing and monitoring the periodontal disease. The periodontal ultrasonography is a reliable technique for visualizing the anatomical elements which are necessary to diagnose the periodontal status. Using this imaging technique the dentino-enamel junction, the cortical bone, the radicular surface from the crown to the alveolar bone, the gingival tissue can be seen without interfering with those elements during the examination. Also, calculus visualization is possible before and after scaling in order to evaluate the quality of the treatment.
Using 2D ultrasonography is not feasible in dental practice as it requires extensive experience and is also time consuming. The reproducibility of the 2D slices is very difficult in order to have the possibility to compare different investigations efficiently. 3D reconstructions of the periodontal tissue can be a very good alternative to eliminate the operator dependence.
Ultrasonography allows the practitioner to visualize the anatomic elements involved in making a periodontal diagnosis. It also allows tracking of subsequent changes. This method is not commonly used for periodontal examination and further studies are required. Previous studies show that ultrasonography can be a reliable non-invasive method to diagnose and monitor the periodontal disease.
Transgredience in Toward Debesija by Bronius Radzevičius
Authors: Grigaitis Mindaugas 
Published: December 2019

The aim of this article is to present the transgredience theory of Russian scientist Mikhail Bakhtin as a compromise of the traditional and postmodern views of literature. Traditional criticism, which here is defined as a metaphysical view of literature as a subject’s self-representation, rejects the postmodern idea of the subject’s death as nihilistic blather. On the contrary, the postmodern attitude denies the subject’s identity as a centre of literature. The theory of transgredience admits that subjectivity is not dead, but rejects it as a constant and finite identity. It makes it possible to join the traditional and postmodern attitudes.The first section deals with these aspects of transgredience. Such categories as time, space, author, hero, exteriority, and inner world are defined. It is stressed that the word man, which traditionally is understood as a subject of constant identity, in Bakhtin’s theory means the possibility to create that identity. This possibility becomes aesthetic reality only when an author—the principle of organizing language—exteriorizes and, through exteriorization, materializes experience in a hero. Exteriorization and the separation of man-authorhero are stressed as the main aspects of the theory of transgredience.The forms of transgredience that are expressed in Radzevičius’s novels are analyzed in the second section. The texts of this author come into the center of analysis because of their intensive correlations of experience and language. It is considered that the best way to present the theory of transgredience as a compromise of traditional and postmodern thought is to use it in an interpretation of the texts of those authors who not only join experience and language into an intense unity, but even feel the boundaries of representing experience through language. Radzevičius is one of those authors.Even though Lithuanian literary critics sees him as a master of creating unity between word and feeling, his texts, as a separate world which is governed by the rules of language, reveal that sometimes feeling absorbs language and novels becomes non-esthetic acts. Such situations are called disturbance of transgredience and have two directions: a) hero absorbs author and becomes an author of his own; b) author absorbs hero and makes him a figure of representing the ideology of the author as a living person. Both directions are described through analyses of certain novels.

OBJECTIVES:
In Lyme disease endemic areas, initial management of children with arthritis can be challenging because diagnostic tests take several days to return results, leading to potentially unnecessary invasive procedures. Our objective was to examine the role of the C6 peptide enzyme immunoassay (EIA) test to guide initial management.

METHODS:
We enrolled children with acute arthritis undergoing evaluation for Lyme disease presenting to a participating Pedi Lyme Net emergency department (2015–2019) and performed a C6 EIA test. We defined Lyme arthritis with a positive or equivocal C6 EIA test result followed by a positive supplemental immunoblot result and defined septic arthritis as a positive synovial fluid culture result or a positive blood culture result with synovial fluid pleocytosis. Otherwise, children were considered to have inflammatory arthritis. We report the sensitivity and specificity of the C6 EIA for the diagnosis of Lyme arthritis.

RESULTS:
Of the 911 study patients, 211 children (23.2%) had Lyme arthritis, 11 (1.2%) had septic arthritis, and 689 (75.6%) had other inflammatory arthritis. A positive or equivocal C6 EIA result had a sensitivity of 100% (211 out of 211; 95% confidence interval [CI]: 98.2%–100%) and specificity of 94.2% (661 out of 700; 95% CI: 92.5%–95.9%) for Lyme arthritis. None of the 250 children with a positive or equivocal C6 EIA result had septic arthritis (0%; 95% CI: 0%–1.5%), although 75 children underwent diagnostic arthrocentesis and 27 underwent operative joint washout.

CONCLUSIONS:
In Lyme disease endemic areas, a C6 EIA result could be used to guide initial clinical decision-making, without misclassifying children with septic arthritis.

Published: December 2019

Background and aimsIndividuals with high level of negative mental health often tend to use the social platform Facebook to escape from daily stress. They are at risk to develop an emotional bond to Facebook linked to a need to stay permanently online. The current work investigated addictive use of Facebook and its conceptual framework in clinical context.MethodsIn a longitudinal study design, duration of daily use of Facebook, addictive Facebook use, depressiveness, insomnia, and positive mental health (PMH) were assessed in a sample of 349 inpatients [Mage(SDage) = 50.13 (9.41)] of a psychosomatic rehabilitation clinic in Germany over a period of on average 6 weeks.ResultsRegression analyses revealed that duration of daily Facebook use at the first measurement time point (T1) served as significant positive predictor of addictive Facebook use at the second measurement time point (T2). Addictive Facebook use (T1) significantly positively predicted depressiveness and insomnia (T2). Its prediction of PMH (T2) was significantly negative. Mediation analyses showed that PMH (T1) partially mediated the association between addictive Facebook use (T1) and depressiveness (T2), and fully mediated the relationship between addictive Facebook use (T1) and insomnia (T2).Discussion and conclusionsCurrent longitudinal results indicate that addictive Facebook use might negatively impact the recovery process of inpatients. Thus, it might be relevant to assess and consider addictive Facebook use in the clinical context. Therapeutic interventions are suggested to focus on the enhancement of inpatients’ PMH level, which may buffer the negative effect of problematic Facebook use.

A busca e o eye tracking: um olhar semiótico sobre o knowledge graph
Authors: Monteiro Silvana Drumond , Rodas Cecílio Merlotti , Vidotti Silvana Aparecida Borsetti Gregório 
Published: December 2019

O eye tracking é, ao mesmo tempo, uma tecnologia e método de pesquisa utilizado em várias áreas do conhecimento e, recentemente, pela Ciência da Informação. Sua tese principal, formulada por Just e Carpenter (1976), é o strong eye-mind, ou seja, a forte relação entre visualização e processamento da informação. Nessa direção, foi feita uma pesquisa básica, com delineamento experimental, visando avaliar o comportamento de busca em uma Search Engine Results Page do Google, em especial a visualização do Knowledge Graph ‒ ou mapa do conhecimento. A premissa da investigação pautou-se na semiótica peirceana, na qual os signos em um resultado de busca ‒ em maior ou menor medida ‒ podem influenciar escolhas, qualificar resultados, capturar o olhar e ser importantes ou determinantes em uma escolha a partir de uma busca, explicando assim o strong eye-mind. Os resultados demonstraram que a imagem é um atrator cognitivo; no entanto, a escolha depende também de outros fatores, como o tipo de busca e o hábito do sujeito em pesquisas nos mecanismos de busca.

Abstract- One of the most widely used processes for CO2 gas removal is Absorption. Carbon dioxide is the result of the fuel combustion process which of the hazardous gases. The aim of this research is to determine the total mass transfer coefficient and analyze the effect of the absorbent flow rate of the absorbent solution with the promoter and the gas flow rate to the total mass transfer coefficient value. The variables consisted of liquid flow rate: 1, 2, 3, 4, 5 liter/min, gas flow rate: 15, 25, 30, 40, 50 liter/min and MSG concentration: 0%, 1%, 3% and 5% by weight. The solution of Pottasium Carbonate as absorbent with MSG promoter is flowed through top column and CO2 gas flowed from bottom packed column. Liquids were analyzed by titration and the gas output was analyzed by GC. From this research, it is found that the flow rate of gas and the liquid flow rate is directly proportional to the value of KGa. The liquid flow rate variable 5 liters / minute, gas flow rate 15 l / min obtained value of KGa 11,1102 at concentration of MSG 5%. Keywords: Absorption, CO2, K2CO3, MSG.
PIPE CONDITION ANALYSIS USING ULTRASONIC TESTING TO PREDICT THE REMAINING SERVICE LIVE (RSL) OF THE PETROLEUM DISTRIBUTION PIPELINE
Authors: Dampang Sarah , Burhan Nanang , Ramayanti Cindi 
Published: December 2019

The pipeline network in the petroleum industry is very susceptible to corrosion. Corrosion problems can cause losses that are not small financially. Corrosion that occurs in underground pipes can be in the form of external corrosion on the outer surface of the pipe caused by acid content in the air or in the soil or internal corrosion inside the pipe caused by petroleum content in the form of water, carbon dioxide (CO2) and hydrogen sulfide (H2S). Corrosion causes the useful or service life of these pipes to be shorter than expected. This study aims to measure the Remaining Service Life (RSL) of the petroleum distribution pipeline as an initial step of preventive action to avoid fatal consequences of corrosion problems. In this study, ultrasonic testing was used as one of the Non Destructive Testing (NDT) methods to check the condition of the petroleum distribution pipe's wall. In this study, it is found that the Remaining Service Life (RSL) of the pipeline under investigation is 25 years.

Authors: Ray G.S. , Lechtig A. , Rozental T.D. , Bernstein D.N. , Merchan N. , Johnson A.H. 
Published: December 2019

Background:
Recent studies in a number of surgical subspecialties have demonstrated that financial relationships with industry differ between men and women. This study aimed to determine if gender disparities exist in industry relationships with orthopaedic surgeons.

Methods:
This retrospective study utilized publicly available data from the Centers for Medicare & Medicaid Services (CMS) at OpenPayments.cms.gov. Data were extracted for payments made to orthopaedic surgeons from industry for royalties, licensing, or consulting fees from 2016 to 2017. A physician’s profile was used to determine name, gender, practice location, and subspecialty. Years of experience were recorded from publicly available websites. Total number of payments and amounts were compared among men and women, subspecialties, and locations. Multivariable linear regression models were used to determine predictors of total payments and number of payments.

Results:
Royalties and consulting fees were paid to 3,418 individual physicians (11% of 29,996 physicians in the American Academy of Orthopaedic Surgeons [AAOS] census) and accounted for 88% of total payments. The majority of the total payment amount (99.6%) was made to men, while only 0.4% went to women. Male gender was a predictor of total number of payments (β = 5.17, p < 0.001), as were years of experience (β = 0.15 [95% confidence interval (CI): 0.10 to 0.20], p < 0.001), Mountain region (β = 2.77 [95% CI: 0.37 to 5.17], p = 0.02), and adult reconstructive subspecialty (β = 4.07 [95% CI: 1.89 to 6.25], p < 0.001). Years of experience (β = 0.046 [95% CI: 0.039 to 0.052], p < 0.001), male gender (β = 1.09 [95% CI: 0.67 to 1.51], p < 0.001), Mountain region (β = 0.35 [95% CI: 0.020 to 0.68], p = 0.04), and adult reconstructive subspecialty (β = 0.33 [95% CI: 0.030 to 0.63], p = 0.03) were associated with higher payments.

Conclusions:
Male gender, years of experience, Mountain region, and adult reconstructive subspecialty are independent predictors of a higher number of industry payments and payment amount. These disparities in industry payments may contribute to continued inequities in scholarship, academic rank, and leadership opportunities.
The Development of a Surgical Mission in the Peruvian Amazon
Authors: Lezak Bradley A. , Cole Peter A. , Schroder Lisa K. , Cole Peter A. 
Published: December 2019

Abstract:
Musculoskeletal disorders and injuries represent a substantial proportion of the global burden of disease. This burden is particularly prevalent in low and middle-income countries that already have insufficient health-care resources. The purpose of this paper is to highlight the vision, the history, the implementation, and the challenges in establishing an orthopaedic surgical mission in a developing nation to help address the epidemic of musculoskeletal trauma.
Scalpel At The Cross (SATC) is a nonprofit Christian orthopaedic surgical mission organization that sends teams of 10 to 20 members to Pucallpa, Peru, a rural town in the Amazon, to evaluate patients with musculoskeletal conditions, many that require surgery. The organization employs 4 full-time staff members and has included over 400 medical volunteers in 32 surgical campaigns since 2005. SATC has provided approximately 8.1 million U.S. dollars in total medical care, while investing approximately 2.2 million U.S. dollars in implementation and overhead.
Given the projected increase in trauma in low and middle-income countries, the SATC model may be increasingly relevant as a possible blueprint for other medical professionals to take on similar endeavors. This paper also highlights the importance of continued research into the effectiveness of various organizational models to advance surgical services in these countries.

Published: December 2019

Case:
A 72-year-old man presented 20 years after a Morel-Lavallée (ML) lesion with pain and drainage. Biopsies of the lesion and lymph nodes were positive for squamous cell carcinoma (SCC). There was no cutaneous involvement or distant metastasis. After chemotherapy and radiation, he underwent resection of the lesion and lymph nodes with flap closure. Two months postoperatively, he unfortunately developed malignant pleural effusions, hypercalcemia, and kidney injury and was eventually transferred to hospice care and died.

Conclusion:
This is the first report of SCC arising from a ML lesion. Chronic ML lesions should be treated aggressively and monitored for transformation into malignancy, even without cutaneous involvement.
Chronic Ulnohumeral Subluxation After Surgical Treatment of Lateral Condylar Fracture Dislocation of the Elbow in a Child
Authors: Park Geun Woo , Jang Woo Young , Lee Soon Hyuck 
Published: December 2019

Case:
A 10-year-old boy presented with chronic ulnohumeral subluxation 6 months after an open reduction of a Milch type II lateral condyle fracture subluxation performed at another hospital. The patient had persistent elbow pain and limited range of motion (ROM) between 20° and 50°. After the open reduction for chronic ulnohumeral subluxation and corrective osteotomy for articular surface reconstruction, he had an uneventful recovery with improved ROM of the affected elbow and no pain.

Conclusions:
Intra-articular corrective osteotomy for articular surface reconstruction may be feasible to improve mobility and relieve pain in pediatric patients with lateral condylar malunion and elbow subluxation.
