Aplicabilidade da termografia por infravermelho na odontologia: uma revisão de literatura atualizada
Authors: Soares Susana Silva , Karam Alexandre Melo
Published: June 2020

Na saúde, o prognóstico está atrelado a um diagnóstico preciso. No entanto, nos exames de diagnósticos por imagem, muitas vezes a subjetividade dos sinais/sintomas, associada à sobreposição de estruturas anatômicas ou presença de artefatos de imagem, dificulta a acurácia de diagnósticos e tratamentos.  Há séculos, é sabido que o excesso de calor ou frio está associado à disfunção ou doença. A termografia por infravermelho consiste em um método de diagnóstico funcional por imagem que permite inferir uma disfunção de um órgão/tecido, através da temperatura. Para tal, baseia-se no registro de diferenças de temperatura corporal e na detecção de padrões de assimetria térmica, em regiões contralaterais do corpo. Diante desse contexto, este trabalho objetiva realizar uma revisão narrativa da literatura atualizada sobre a aplicabilidade da termografia por infravermelho na Odontologia. Para a confecção deste trabalho, foram utilizados artigos que abordaram o uso da termografia infravermelha na Odontologia, no período de 1956 a 2019. No panorama atual, em que princípios como: sustentabilidade, eficácia, promoção de saúde e prevenção de doenças, ditam as diretrizes de saúde mundial, este trabalho corrobora com a concepção de que a inserção do exame termográfico na Odontologia pode favorecer diagnósticos precoces de disfunções/patologias, proporcionar um melhor direcionamento para outros exames mais específicos e contribuir para escolha de terapêuticas mais assertivas. Desta forma, embora a termografia por infravermelho ainda possua uma literatura incipiente e uma confiabilidade questionável, a utilização deste método auxiliar de análise mostra-se bastante promissor na Odontologia e em diversas outras áreas da saúde e do conhecimento.

The study of thermophysical properties of ceramics with the addition of the pyrolysis residue of solid waste
Authors: Kolibaba O.B. , Dolinin D.A. , Gabitov R.N. , Shavitova M.O.
Published: June 2020

A promising environmentally friendly method for processing municipal solid waste is pyrolysis. Pyrolysis allows obtaining a combination of solid, liquid and gaseous products in various proportions due to changes in process parameters. A promising area for the use of solid pyrolysis products is the production of various materials for industrial, civil and road construction. There are some known methods for producing cement, concrete and foam glass with improved properties on pyrolysis basis. In modern building technologies, ceramic materials are widely used. Their production requires various expensive additives such as quartz sand, dolomite, coal, coal mining rocks, etc. Thus, it seems relevant to use the residue of the pyrolysis of municipal solid waste as a free of charge structure-forming additive for the production of ceramic material. To determine the scope of the material application and to perform subsequent thermotechnical calculations, the data on its thermophysical characteristics is required. To determine the thermophysical characteristics of the ceramic material, the experimental method of the cylindrical layer and the calculation-experimental method of inverse heat conduction problem are used. The experimental studies of thermophysical properties of the new ceramic material have allowed obtaining the dependence of the average specific heat capacity and thermal diffusivity of the ceramic material on temperatures in the range of 30–90 оС, and the coefficient of thermal conductivity on the temperatures in the range of 30–500 оС. These characteristics enable to perform calculations of thermal processes that occur in the material during its industrial use. The coefficient of thermal conductivity of the material varies from 0,3 to 0,65 W/m×K, thermal diffusivity varies within (1,8–2,3)×10–7 m2/s, and the average specific heat capacity changes from 780 to 1300 J/kg×K, which is comparable with the thermophysical characteristics of known ceramic materials. It is advisable to use the pyrolysis residue of municipal solid waste as a free raw material instead of expensive additives to obtain ceramic material. It is recommended to use the new ceramic material in the production technology of building products for various purposes.
The development of multi-channel control system for a multi-phase synchronous electric drive with improved vibration noise characteristics
Authors: Golubev A.N. , Belonogov V.G.
Published: June 2020

Constantly increasing requirements for the performance of electromechanical systems include the task of improving the vibration and noise characteristics of the electric drive. Currently, this problem is solved mainly by using traditional three-phase systems. The transition to a multiphase version of the electric drive construction opens up new opportunities for its solution. The aim of the study is to improve the vibration and noise characteristics of the electric drive through the development of a multiphase control system that provides targeted formation of the field configuration in the gap of a multiphase electric machine. To conduct the research, the model of a multiphase synchronous motor proposed by the authors was used. The model considers the spatial non-sinusoidality of the field distribution in the gap and enables to represent the engine as a set of parallel substructures, the number of which depends on the number of phases. The technique to design a synchronous motor with an arbitrary number of winding phases based on the field model of the machine has been proposed. The correctness of the results obtained is ensured by the real geometry of the magnetic circuit and steel saturation. The multi-channel control system of the electric drive, characterized by the targeted formation of field configuration in the gap of a multiphase electric machine has been proposed. The calculation model of the electric drive has been developed. The model combines the field model of the engine and the control system. The engine model is implemented in the ElСut software package, the control system model is implemented in the MatLab (Simulink) complex. Compared to the traditional three-phase design of the electric drive with a sinusoidal supply voltage, the options for forming a field in the gap of a synchronous motor considered in the article provide a reduction in ponderomotive force by 8–14 %. The engineering methodology for designing an m-phase synchronous permanent magnet motor with permanent magnets and the structure of the multi-channel control system can be applied when developing electric drives with improved vibration and noise characteristics.
Health and Scientific Frames in Online Communication of Tick-Borne Encephalitis: Antecedents of Frame Recognition
Authors: Kohler Sarah , Koinig Isabell
Published: June 2020

In a period characterized by vaccine hesitancy and even vaccine refusal, the way online information on vaccination is presented might affect the recipients’ opinions and attitudes. While research has focused more on vaccinations against measles or influenza, and described how the framing approach can be applied to vaccination, this is not the case with tick-borne encephalitis, a potentially fatal infection induced by tick bites. This study takes one step back and seeks to investigate whether health and scientific frames in online communication are even recognized by the public. Moreover, the influence of selected health- and vaccine-related constructs on the recognition of frames is examined. Study results indicate that health frames are the most easily identified and that their use might be a fruitful strategy when raising awareness of health topics such as vaccination.

Authors: Kostenko Natalia , Ivanov Valerii
Published: June 2020

The Academy of Ukrainian Press since 2002, with the participation of scientists of the Institute of Sociology of the NAS of Ukraine, conducts research of prime time news (19:00-23:00) of the leading Ukrainian TV channels. Monitoring is carried out by content analysis, that is, a quantitative method of document study, characterized by rigor of the procedure and reliability of conclusions, and consists in quantitative processing of the text with subsequent interpretation of the results.

The article looks at the main trends that were identified in the March 2019 Prime Time News Analysis:

Political news in Ukraine focuses on March programs. Only 1+1 is traditionally dominated by all other news about Ukraine. The intensity of attention to political news varies markedly. The main source of information is media’s own correspondents.
Attention to the presidential election increased from 18% to 22% compared to February 2019 news.
Channels are heterogeneous in their focus on the 2019 election theme. Every third announcement on Ukraine on Inter, Ukraine, ICTV channels is electionrelated; each eleven on the 1st and twelve on the 5th.
In the news, 17 presidential candidates were mentioned out of 44 registered by the CEC (39%, in February 34%). The most frequently reported was the campaign of Yulia Tymoshenko, O. Vilkul, P. Poroshenko, and O. Lyashko.
The highest attention in the news to the candidate politicians P.Poroshenko, Y.Tymoshenko, O.Lyashko, O.Vilkul, Y.Boyko.
Only in a positive and neutral context was A. Gritsenko mentioned, and in the least ironic and negative about Y. Boyko and Y. Tymoshenko. The most frequently mentioned in the ironic and negative are Yuri Tymoshenko and E. Muraev.
P. Poroshenko, O. Vilkul, O. Lyashko, Y. Tymoshenko, and Y. Boyko had more time in the news. For two months in a row V. Zelensky has been in sync only in 1+1 news. Channels are markedly segmented by their political preferences, adhering strictly to their own election campaign strategies.
First Commercial Private Radio Stations in Ukraine: From Experiments to Business
Authors: Goian Oles , Goian Vita
Published: June 2020

The article concerns the first two years (1992-1993) of the formation of commercial broadcasting in Ukraine. It studies the factors that influenced the creation of the first commercial radio stations, which gradually attempted to switch from a “game mode” to the broadcasting business and business entrepreneurship. The activity of the first ten commercial radio companies is studied by means of systematization, content analysis, generalization and other methods. The authors of the article offer the documented time of the first airwaves of each company mentioned (from the authors‟ personal archives). The role that these stations played in the formation of commercial private broadcasting in Ukraine is analyzed. Additional information is given about the creation of the Association of Private Radio Stations in Ukraine which was intended to unite commercial radio stations. The minute of the seminar “Local Radio” is published for the first time. The meeting with the head officers of the radio stations present was organized by the public organization International Media Center – Internews (Ukraine) and by the training center British Broadcasting Corporation (BBC, England) from May 20 to June 3, 1994 in Pushcha-Vodytsia near Kyiv. It was there where they decided to create the association. One of the radio projects of MMC-Internews “Interview from Internews” is examined. It may be considered as the first radio project unifying commercial radio stations, and also the first student radio project at the private radio station in Ukraine. Therefore, the purpose of the article is to study facts and documents (from the authors‟ personal archive) certifying the dialectic progress of Ukrainian commercial broadcasting from the so-called “musical patchwork” to the transformation into a profitable means of mass communication.

Authors: Sydorenko Natalya , Volobuieva Anastasiia , Zental Olesia
Published: June 2020

The aim of this study is to analyze the representation of women in human rights media discourse during the armed conflict in the east of Ukraine in 2014–2019. Thus, critical discourse analysis was conducted using monitoring methods, qualitative content analysis, comparison, analysis, synthesis and generalization. For the first time, methodological innovation was introduced by combination of critical discourse analysis with agenda-setting theory through application of an integrative approach to the
research. Within media texts analysis, the discourse practice of using genres, interdiscursivity and intertextuality was identified. The existing social practice in Ukraine was studied which included women’s defence of their rights to serve in various army units; at the same time, one could observe a struggle between political discourse and the ideology of paternalism as well as between human rights protection discourse and ideology of feminism.
An analysis of social practice was also conducted, and for the first time, a methodological innovation was implemented by combining critical discourse analysis with agenda-setting theory using an integrative approach in the research. In particular, it was found that due to the media discourse reproduction of social inequality, members of the public competed for their agenda with politicians. It was found that in case of women’s struggle for their rights in the army during the armed conflict, there was
a conflict between human rights discourse of feminism ideology and political discourse of paternalism ideology. This study shows that in the studied conflict’s discriminatory situation, women succeded in defending their rights to serve in the army during the armed conflict in the eastern Ukraine, and, accordingly, human rights discourse succeded in the media space.
“Heart of Darkness” and “Dark Continent”: Africa and its Nations in Polish Media and Social Perception
Authors: Bodziany M. , Nowakowska M.
Published: June 2020

Objectives. The cognitive purpose of the article is to describe the stereotype of the Africans in the profiles of stereotypical perception of the Poles, created under the influence of the media and the low level of cultural competence of the Poles, as well as to identify the Poles’ attitudes towards the Africans and social problems arising in mutual relations.
Background. The image of Africa and its inhabitants in the social perception of Poles is an issue still under-studied and burdened with deficit empirical knowledge. He is burdened with stereotypes created over many years by building a distorted image of Africa through the media and pop culture. An important determinant of the subjective image of the inhabitants of Africa in the perception of Poles is also their lack of cultural competence, which is based on the small population of Africans in Poland and limited contacts with them, as well as the lack of tendency of Poles to expand their knowledge about other nations.
Methodology. The article is based mainly on qualitative research — on the analysis of secondary data (desk research) coming from research reports, which are supplemented by the results of quantitative research on the perception of refugees and immigrants in the opinion of the young generation of the Poles. The essence of the article is an attempt to answer the question: what is the image of Africans and Africa in Poland and to what extent is it changing?
Conclusions. However, the stigmas of the past seem to be disappearing, and Polish society is also opening up to the world in terms of culture. thanks to this, changes in the perception of Poles are visible not only towards Africans but also to other nations. The increase in the population of „foreign” nationalities, including those from Africa, as well as the spatial mobility of Poles observed in Poland mean that the image of Africans is changing. It is still a slow process, but it shows change — moving away from misperception and stereotypes in favor of knowledge and openness.

Published: June 2020

The aim of all education systems is to train students who are equipped with knowledge. In that case, that student is able to determine the most suitable profession for him/her success in education and career that are related to this profession will be higher. Studies done up to this day have been focused on finding out the factors affecting the career choice of the student, but they have not suggested any method for determining the most suitable procession. It is not possible to obtain satisfying results from a system that does not lead students to appropriate higher education departments. In this context, a student- department matching system is proposed which aims to increase the success of the education systems in our study. The department of computer engineering was dealt with as a sample department and the proposed study was examined to determine whether a student was suitable for computer engineering or. The required data was obtained with the help of the questionnaire, and then a model of successful and unsuccessful students was created. Data mining algorithms such as C4.5, C SVC, MLP, and Naïve Bayes are used during the test of the generated model. The best result was obtained by the C-SVC algorithm and the second best result by Naive Bayes. The lowest error rate achieved was 0.2700 and the highest accurate recognition rate was 73.00%.
Two lagrangian relaxation based heuristics for vertex coloring problem
Authors: MAHMUTOĞULLARI Ali İrfan
Published: June 2020

Vertex coloring problem is a well-known NP-Hard problem where the objective is to minimize the number of colors used to color vertices of a graph ensuring that adjacent vertices cannot have same color. In this paper, we first discuss existing mathematical formulations of the problem and then consider two different heuristics, namely HEUR-RA and HEUR-RC, based on Lagrangian relaxation of adjacency and coloring constraints. HEUR-RA does not require solving any optimization problem through execution whereas at each iteration of HEUR-RC another NP-Hard problem, maximal weight stable set problem, is solved. We conduct experiments to observe computational performances of these heuristics. The experiments reveal that although it requires longer running times, HEUR-RC outperforms HEUR-RA since it provides lower optimal gaps as well as upper bound information.
Comparison of functionally graded and ungraded cylinder liners with finite element analysis
Authors: ERTEK Cem , CİVELEK Fatih
Published: June 2020

In this study, functionally graded and ungraded Al-Si cylinder liners have been compared by the finite element analysis. At the beginning of the study, the most sold gasoline-powered automobiles in recent years have been investigated and the dimensions of the Al-Si cylinder liner have been determined. Al-Si alloy based cylinder liners with a wall-thickness of 6 mm and inner diameter of 74 mm, an outer diameter of 86 mm and a length of 165 mm have been designed. The functionally graded cylinder liner has a twenty-layered structure, and the silicon content of each layer is distinct. Si contents on the inner and the outer surfaces of the functionally graded liner are 32 vol.% and 8.5 vol.%., respectively. The ungraded cylinder liner, on the other hand, has a homogeneous structure and the silicon content of 21 vol.%. The maximum Von Mises stresses reached as a result of thermal loads in the functionally graded and ungraded cylinder liners are determined to be 47.526 MPa and 95.951 MPa, respectively. It has been observed that maximum Von Mises stress decreases by approximately 50% thanks to the functional grading.
Post-op bore profile estimation of workpiece clamped using three-jaw chuck
Authors: GÜVEN Fatih
Published: June 2020

Estimating bore profile is important to select an appropriate tool for precision manufacturing in the process planning stage. Also, it helps in reducing the rejection rate of the process. A manufacturer might not be well-equipped and want to make their best with the resource on hand. Three-jaw chuck allows machining a wide range of workpiece, mostly circular parts in a lathe. However, clamping via a three-jaw chuck distorts the workpiece. In this study, the deformation of the bore profile was investigated numerically for circular parts. Finite element analyses were performed to examine dimensional variation for various materials and different wall thicknesses under fully elastic plane stress conditions. The stressed workpiece had a triangular form. Results showed that wall thickness and materials are important parameters on the triangulation of bore diameter. A simple calculation method based on thick-walled vessel theory was proposed to estimate the tolerance grade of the workpiece. This simple method provides the opportunity to reduce the rejection rate in the mass production of circular parts.

Published: June 2020

In this study, polyhedral oligomeric silsesquioxane-N-acetylcysteine (POSS-NAC) conjugate as a potential antioxidant molecule was synthesized from N-acetylcysteine (NAC) and amino-functional POSS structure by click chemistry. The chemical structures and thermal properties of the synthesised POSS-NAC conjugate was characterized by spectroscopic and thermal analysis techniques. The antioxidant capacity of the POSS-NAC conjugate was also determined by the 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity and reducing power methods. According to the reducing power method, POSS-NAC structure has lower reducing activity than standard ascorbic acid and trolox (p<0.001). It was found from the ABTS radical scavenging activity results that the synthesized POSS-NAC conjugate had a significantly higher radical scavenging effect than the standards (p <0.001). Biocompatibility properties of the POSS-NAC structure were detected in vitro cell culture system with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test on L-929 mouse fibroblast cells. The synthesized POSS-NAC conjugate exhibits high antioxidant activity and good biocompatibility.
Certain results on Kenmotsu manifolds
Authors: YOLDAŞ Halil İbrahim
Published: June 2020

In this paper, we focus on Kenmotsu manifolds. Firstly, we investigate almost quasi Ricci symmetric Kenmotsu manifolds. Then, we study Kenmotsu manifold admitting a Yamabe soliton. We find that if the soliton field of the Yamabe soliton is orthogonal to the characteristic vector field then it is Killing and the manifold has constant scalar curvature. Also, we deal with a Kenmotsu manifold which admits a quasi-Yamabe soliton. Finally, we give an example which verify our results.

Authors: ELÇİ Şükrü Gökhan
Published: June 2020

In this research, a magnetic solid phase extraction based on the use of magnetic polyaniline-polythiophene copolymer (Fe3O4@coPANI-PTH) nanoparticles is applied for chromium speciation from water, beverages and seasoning samples followed by microsample injection system-flame atomic absorption spectrometry(MIS-FAAS) analysis. The selective adsorption of Cr(III) in presence of Cr(VI) by Fe3O4@coPANI-PTH in the pH range of 9.0-10.5 was obtained and the total Cr, after reduction of chromium(VI) to chromium(III) by adding 0.5 mL of concentrated H2SO4 and 10 mL of 5% (w/v) hydroxylamine hydrochloride, was determined. The detection limit, enhancement factor, and repeatability of the optimized method for Cr(III) were calculated to be 1.5 µg L-1, 38.5, and 1.78%, respectively. The method was validated by the analysis of TMDW-500 drinking water and LGC7162 Strawberry Leaves as certified reference materials. The relative error for total chromium was found to be lower than 4.6%. Recoveries were obtained quantitatively using this method (≥95%).

The spring field pea is one of the most important coarse legumes. This study was carried out to investigate the response of a spring field pea variety to three plant densities (50, 100, and 150 plant m-2) during the 2017 and 2019 growing seasons in eastern Croatia. The field study was set up as a Randomized Complete Block Design (RCBD) in four replications. The results have demonstrated a significant effect of the plant densities and the growing seasons on the seed yield and on the following yield components: plant height and the number of pods/plant. The effect of plant densities on the number of seeds/pod and the thousand-seed weight was not significant. As for a growing season, the highest seed yield, plant height, the number of pods/plant were obtained in the second growing season. Furthermore, a maximum seed yield was recorded at the 150-plant m-2 plant density. This study has demonstrated that planting the spring field pea at different plant densities significantly modifies the spring field pea yield, plant height and number of pods/plant.

Authors: Jaywant Shailaja S. , Kale Jayashri S.
Published: June 2020

Background: Premature infants often have feeding difficulties leading to morbidity or developmental co-morbidities. Premature infant oral motor intervention (PIOMI), has shown the positive effects on feeding progression of the premature infants. PIOMI with the massage technique, may help in improving oral motor activity, weight gain in preterm infants along with better neurobehavioral organization. The study was done to analyse effect of this combined protocol on achieving oral motor control and Neurobehavioral state regulation and evaluate its efficacy against PIOMI.Methods: A total 72 clinically stable infants admitted in premature care unit, fulfilling inclusion criterion were enrolled. They were allocated in control and experimental group. Infants from control group received PIOMI and experimental group received PIOMI with massage therapy (M technique), for 10 minutes each day. Data was collected for oral motor abilities, behavioural assessment, weight and day of achieving full feeds.Results: Gestational age at full feeds was 33.65 weeks and 32.89 weeks in control and experimental groups respectively with ‘p’ value 0.002. The number of days of full feed in experimental group was 3.7 days earlier (p=0.04). Infants from experimental group showed higher oral motor score and more weight gain with significant difference The behavioral regulation in infants of both the groups improved after 8 day.Conclusions: PIOMI with M technique was well tolerated by preterm infants. The modified protocol has resulted in achieving early oral feeds and reducing hospital stay. It has also shown the benefit of behavioural regulation along with better oral motor control.

Background: Hypertension is the one major global burden disease, causes 7.5 million deaths i.e.12.8%. Coronary Heart Disease Prevails 3-4% rural and 8-10% of urban population under 20 year’s age in India. Two fold rise in rural & six fold rise in urban areas since four decades. Environmental and Genetic factors i.e. Sex, BSA, obesity, family history of hypertension, dietary habits, physical activity, stress, race, ethnicity and socio economic status influence on children and adolescent. Many studies have established normal standards of BP for the children of different ages and races in their countries. Indian children cannot be adopted due to differences in ethnic, socio-economic, dietetic, environmental and emotional factors.Methods: A cross sectional study done with 2422 children of 5 to 16 years age school children, selected from 13 Schools (Government and Private) of Urban and Rural areas of Warangal.Results: A linear increase in mean BP with age, sex, weight, height, social status and locality. DBP has strong negative correlation with sex. i.e. female have high DBP and children of lower class and rural area has high DBP. 54 children <85th and 95th percentile and 5 children >95th percentile has comparatively high mean BP, 27 children with history of Hypertension in parents are >85th and 95th percentiles. Positive correlation with BMI in both sexes studied. A multivariate regression study confers positive strong correlation of Mean SBP and DBP with anthropometry.Conclusions: Observed similar results of SBP and DBP in both sexes, linear Increase in mean SBP and DBP with increasing age, weight, height and BMI. Family history of hypertension and high SES had direct correlation to SBP and DBP; class I SES has higher Mean SBP than class III SES.
Anti NMDA receptor encephalitis: a potentially treatable encephalitis
Authors: M. Archana K. , Save Sushma , Gautam Koppikar Rahul
Published: June 2020

Anti NMDA receptor encephalitis is autoimmune encephalitis where antibodies are directed against NMDA receptor subunit. It represents a new category of immune-mediated disorder that is often paraneoplastic, presenting with neuropsychiatric symptoms, which is treatable and can be diagnosed serologically affecting both children and adults. Patient can have variable clinical presentation ranging from prodromal illness, neuropsychiatric symptoms, seizures, autonomic instability, hyperkinesias, catatonia, hypoventilation and with or without an associated teratoma. A positive serum or CSF sample screening for antibodies to the NMDA receptor subunit is confirmative. Supportive findings include CSF study, EEG and MRI Brain. The first-line therapies includes IVIG, corticosteroids or plasma exchange. Second line immunotherapy is rituximab or cyclophosphamide or both. Given the high mortality rate (up to 25%), the likelihood of presentation across the age range and the potential for treatment, a high index of suspicion is warranted by clinicians. Authors report a case of a 5 year old child with anti NMDA receptor encephalitis who responded well to IVIG therapy.

Published: June 2020

Precocious puberty is defined as children attaining puberty more than 2.5 to 3 standard deviations (SD) earlier than the median age, or before the age of eight years in girls and nine years in boys. Hypothalamic hamartoma (HH) are rare, non progressive tumor like malformation. Precocious puberty due to HH occurs particularly at early ages, even 2 or 3 years. Treatment options for isolated CPP due to HH include GnRH analogs agonists continuously stimulates pituitary gonadotrophs, which further help in decreasing and desensitizing the release of LH, and to a lesser extent, FSH till the time puberty naturally set in. We present a case of precocious puberty due to hypothalamic hamartoma in 3 years old girl. Treated with GnRH analog lupirode and responded well to treatment with cessation of menstruation and reduction in breast size.

Authors: Meena Mahaveer , Chavan Vikas , Ghilley Sanjay Kumar , Jangir Nilesh Kumar
Published: June 2020

Background: Open fractures are surgical emergencies; incidence of open fractures is increasing with more high-energy road traffic accidents. The tibia is exposed to frequent injury because of its location. The need for aggressive debridement, adequate fracture fixation, and early flap coverage in reducing the morbidity cannot be over emphasized.

Methods: Treatment of open fracture by immediate debridement and anatomical fracture reduction using external fixator device. Gastrocnemius muscle flap done in upper 1/3 open fractures (type IIIB) with larger defects along with split thickness skin graft (STSG). In middle and lower 1/3 open fractures (type IIIB), fasciocutaneous and soleus muscle flaps done with relatively smaller soft tissue defects and exposed bone with STSG.

Results: The study included 15 patients with open tibia fracture Gustillo Anderson type IIIB classified after the initial debridement. Excellent flap takes up was seen in all cases. 11 cases (73.3%) achieved union at the end of 6 months follow-up while 4 cases (26.7%) showed delayed union which required additional procedures like BMI or bone graft.

Conclusions: Soft tissue coverage techniques like fascicutaneous flap, gastrocnemius and soleus muscle flap had a definitive role in the management of open fractures of tibia (type IIIB).

Published: June 2020

Background: Repair of degenerative rupture of tendoachilles is a challenge for orthopaedician. We used peroneus brevis tendon in our patients to augment the repair of degenerated tendoachilles tears by creating a dynamic loop.

Methods: In our study, we evaluated 31 patients with Achilles tendon rupture treated by reconstruction using peroneus brevis tendon transfer by dynamic loop suture technique. The patients were from all age groups excluding those lesser than 35 years. The average follow-up being 6 months.

Results: In total 31 patient’s majority of patients belong to 41-50 years (15 cases 48.4%). Male patients being 24 (77.4%) constituted the majority, right sided injury was noted in 23 (74.2%) of the patients. Most common symptom of Achilles tendon rupture is pain. The mechanism of injury in most of the patients by stumbling in the fields in 19 (61.3%). Results of testing the patient’s ability to heel raise for 60 seconds 20 patients were able to sustain, while 8 patients were able to stand on toe with heel raised but could not sustain it. 3 patients could not do raise the heel. 5 patients complained of sensory hypoesthesia at 12 months follow-up. By Rupp scoring, 77% patients had excellent or good results and 10% had fair or poor results.

Conclusions: Results of reconstruction of Achilles tendon ruptures using peroneus brevis tendon show a strong and stable repair that allows early weightbearing ambulation with favourable clinical results in most patients.

Published: June 2020

Percutaneous vertebroplasty is a safe and effective minimally invasive procedure with specific potential complications. Among these, vascular injuries have seldomly been reported. We present a rare case of retroperitoneal hematoma, presumably from injury to one of the lumbar arteries following percutaneous vertebroplasty in a patient treated for lumbar fracture. Even though the situation was life-threatening, conservative treatment and support measures sufficed in controlling the bleeding and the patient recovered fully. Spine surgeons should be especially aware of this specific and often late-presenting complication, as early recognition and prompt treatment are fundamental to decrease its morbidity and mortality.
