Published: April 2018

Analysis of the results of surgical treatment of 63 patients with knee-joint pathology who were treated in Vreden’s Scientific-research Institute of traumatology and orthopaedics (Saint-Petersburg, Russia) within the period from 2000 to 2011. All the patients had pedicled flap transfer or free tissue transfer. 53 patients (84,1%) had additionally various orthopedic operations on the knee joint: 42 patients had primary or revision total knee arthroplasty, 6 patients had resections of bony tumors and total knee arthroplasty, 4 - knee arthrodesis, 1 - open reduction and internal fixation of patella. The results of treatment were estimated according to WOMAC knee score. 4 patients had total necrosis of flap what demanded repeated reconstructive microsurgical operation. 6 patients had knee arthroplasty surgical site infection, 1 patient had recidive of osteoblastic sarcoma and he was made leg amputation. 65,7% of patients had good results according to WOMAC knee score, 28,6% patients had satisfactory results. Microsurgical operations in patients with pathology of knee-joint mainly aim to correct various pathological changes of tissues located in this particular area. In cases of scarry deformations and defects of tissues located in the area of knee-joint microsurgical technologies increase the opportunities for fulfilling total knee arthroplasty and improve its results as well as results of other orthopedical operations. At the same time microsurgical technologies may be used as preparative operations, single-step maneuvers and operations fulfilled in case of development of local infectious complications.

Published: April 2018

The authors analyzed the long-term results of surgical treatment 47 patients with true spondylolisthesis. The follow up period ranged from 14 to 25 years. All patients underwent an isolated anterior interbody riving allograft fusion. The scales of VAS and ODI were used for subjective assessment of treatment outcomes; objective assessment was based on clinical and radiographic, CT and MRI outcomes. There were 42.6% (20 cases) patients with good, 31.9% (15 cases) with satisfactory and 25.5% (12 cases) unsatisfactory results in the long-term follow-up. The main reasons of poor outcome were: the continued high degree of displacement of the vertebral body (17.6%), instability (38.3%) and the disbalance of the lumbosacral spine (63.8%), persistent compression of neural structures (42.6%). Most patients had the combination of these factors that were existed against backdrop of progressive degenerative changes of the spine.

Published: April 2018

Osteochondroma is the most common tumor of the skeleton. Its frequency is more than 40% of benign and at least 20% of all human bone tumors. The objective of this study was to improve methods of diagnostics of shin bone osteochondromas with using of modern imaging techniques. There were treated 81 patients with primary tibia osteochondroma and one with a secondary chondrosarcoma during the period from 2000 to 2011 in the Clinic of Traumatology and Orthopedics of the Astrakhan Medical Academy Diagnostics was based on the data of anamnesis, physical examination, standard X-rays and computed tomography. We applied ultrasound studies of shin bones in 11 patients. The ultrasonography has allowed revealing two main forms of osteochondromas: “globular-shaped” and “hill-shaped”. The tumor goes into the third “cauliflower-shaped” form in the case of malignant transformation. The distribution of the cartilage on the osteochondroma surface is irregular and depends on the tumor shape. The indirectly malignant signs are the loss of sharpness and smoothness of the contour, hyperechoic inclusions in the cartilage cap.

The authors determined the characteristics of secondary scar deformities in children depending on its localization and specificity of the primary injury. For the period from 2008 to 2010 we examined and treated 184 children with scar deformities of varying degrees of severity and location. The examination included: clinical methods including neurological examination, as well as rentgenography, electroneuromyography, ultrasound, CT and MRI, depending on indications. In addition, depending on the localization of a deformity were performed stabilographic and biomechanical studies. Surgical and medical treatment of cicatricial deformity in children depends on the anatomical and physiological characteristics of the affected segment. In planning the reconstruction of treatment, must be taken into account the conditions of local blood circulation, which can vary greatly depending on the duration of the existence the deformity and the etiology of the primary lesion.

ATYPICAL FRACTURES DUE TO LONG TREATMENT WITH BISPHOSPHONATES (CRITICAL REVIEW)
Authors: Golubev G. S.
Published: April 2018

This paper reviews the evidence for an association between atypical subtrochanteric fractures and long-term bisphosphonate use. A PubMed search of literature was performed. Estimation of scientific level of evidences, extraction of quantitative data about atypical fractures from publication were performed. Common clinical and X-ray features of ‘atypical’ fractures are described. Level IV publications contain assumptions of relationship between long term (more than 5 years) bisphosphonates’ (alendronate, ibandronate) treatment and atypical fractures. No data found about connection between zoledronic acid and atypical fractures. Data about relative risk of atypical fractures which is retrieved from meta-analysis’s and post-hock analysis’s of randomized clinical investigations is discrepant. No meta-analysis’s and randomized clinical investigations with statistically valid evidence of correlation between atypical fractures and long term bisphosphonates treatment have been found. Despite the relative rarity of atypical femoral fractures and doubtful evidences of their connection to bisphosphonates therapy, physicians and patients should be made aware of the possibility of such phenomenon. Principles of rational bisphosphonates therapy are being discussing. Because bisphosphonates accumulate in bone, they create a reservoir leading to continued release from bone for months or years after treatment is stopped. The feature described above is the base to recommendation for a drug holiday after 5-10 yr of bisphosphonate treatment. Clinical recommendations to reduce risks, rational diagnostic and surgical algorithm to treat atypical fractures are proposed for physicians dealing with osteoporosis, osteoporotic fractures and their consequences. Researches should be undertaken to get additional epidemiologic and clinical data to establish the true relationship between atypical fractures and long term bisphosphonates using. Bisphosphonates are effective and relatively safe remedies which reduce risk of osteoporotic fractures of any part of skeleton. Clinical advantages of bisphosphonates using exceed the doubtful and unproved risk of atypical fractures.

Authors: Dianov S. V.
Published: April 2018

Recurrence of a giant cell tumor or a malignization of the bone (osteoclastoma) is a common complication after surgical treatment. Increased surgical radicality in such pathology is an acute issue. Ablastic procedure can be performed by exposure to ultralow temperatures.Purpose — to improve the surgical treatment efficiency of osteoclastoma by uncontrolled cryodestruction of the visual cells and tissue elements in the resection of the tumor-affected bone.Material and methods. Experimental studies on tumor fragments in vitro. Pathological tumor tissue was three times treated with liquid nitrogen (boiling point −195.8°C). The time of each freeze-defrost cycle was up to three minutes. In the clinical practice, the same cooling agent instillation of the bone defect after resection and mechanical removal of the tumor was used in 67 patients (52 cryosurgical interventions and 15 traditional resections).Results. In the study the authors used the methods of evidence-based medicine. After instillation of liquid nitrogen on giant cell tumor the temperature of −154°C was noted. In the area of cryotreatment 80% of necrotic tumor tissue was identified morphometrically. The study of 67 operated patients demonstrated that positive results were obtained in 40 cases among patients exposed to cryogenic treatment and recurrent was observed in 8 cases. Good outcomes after conventional surgery were observed in 7 patients and recurrence of tumor was reported in 5 cases.Conclusion. Positive experience of cryosurgical procedures allows to restrict indications for articular and extensive segmental resections in favor of intrafocal and marginal resections with cryodestruction and bone defect grafting. The method allows to expand a preservation trend in orthopedic oncology.

Authors: Wu Chia-Lin , Chang Chia-Chu , Kor Chew-Teng , Yang Tao-Hsiang , Chiu Ping-Fang , Tarng Der-Cherng , Hsu Chih-Cheng
Published: April 2018

Background and objectives

Hydroxychloroquine is widely used in patients with rheumatoid arthritis. However, large-scale studies examining the long-term effects of hydroxychloroquine on the development of kidney disease in patients with rheumatoid arthritis are lacking. We aimed to assess the long-term association of hydroxychloroquine use with the risk of developing CKD in this population.

Design, setting, participants, & measurements

We conducted an observational cohort study for patients with newly diagnosed rheumatoid arthritis who were enrolled prospectively in Taiwan’s National Health Insurance Research Database between January 1, 2000 and December 31, 2013. We used multivariable Cox proportional hazard regression to analyze the association of hydroxychloroquine use with incident CKD.

Results

A total of 2619 patients, including 1212 hydroxychloroquine users and 1407 hydroxychloroquine nonusers, were analyzed. Incident CKD was reported in 48 of 1212 hydroxychloroquine users and 121 of 1407 hydroxychloroquine nonusers. The incidence rate of CKD was lower in hydroxychloroquine users than in hydroxychloroquine nonusers (10.3 versus 13.8 per 1000 person-years). After multivariable adjustment, hydroxychloroquine users still had a lower risk of incident CKD (adjusted hazard ratio, 0.64; 95% confidence interval, 0.45 to 0.90; P=0.01) than hydroxychloroquine nonusers. The lower risk of subsequent CKD development was dose dependent and consistent across subgroup analyses.

Conclusions

Hydroxychloroquine use in patients with newly diagnosed rheumatoid arthritis is associated with a significantly lower risk of incident CKD compared with in nonusers.

Published: April 2018

Global warming and climate change has reached the alarming levels due to increase of greenhouse gas emissions into the atmosphere which includes carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Flooded rice (Oryza sativa L.) cultivation has been identified as one of the prominent global agricultural sources of anthropogenic CH4 emissions. Moreover, it has been estimated that global rice production is responsible for 11% of total anthropogenic CH4 emissions. The inventory of CH4 emission from rice cultivation in Malaysia was estimated from 1990 to 2014 and was also used as basis for computing the projected emissions up to 2030 by using Auto-Regressive Integrated Moving Average (ARIMA) model. Results showed that CH4 emissions is higher from granary area (continuously flooded) than non-granary area (rain-fed) due to different water management practices. Continuously flooded irrigation system which lead to anaerobic conditions emit almost (75%) higher CH4 than rain-fed irrigation system. Emissions forecasted will be continuously increase from 2015 to 2030 within the confidence limits. Emissions were forecasted to increase up to 88 Gg by 2030 due to increase of country population which will lead to expansion of cultivation area in order to fulfil country needs.

SOME FIXED POINT THEOREMS FOR GENERALIZED $\alpha$-GERAGHTY CONTRACTION TYPE MAPPINGS IN $B$-METRIC~SPACES AND SOME APPLICATIONS TO THE NONLINEAR INTEGRAL EQUATION
Authors: Hieu Nguyen Trung , Chac Le Thi
Published: April 2018

The purpose of this paper is to introduce the notion of a generalized $\alpha$-Geraghty contraction type mapping in $b$-metric~spaces and state the existence and uniqueness of a fixed point for this mapping. These results are generalizations of certain the main results in [D.~\DJ uki\'{c}, Z.~Kadelburg, and S.~Radenovi\'{c}, \emph{Fixed points of Geraghty-type mappings in various generalized metric spaces}, Abstr. Appl. Anal. \textbf{2011} (2011), 13 pages] and [O.~Popescu, \emph{ Some new fixed point theorems for $\alpha$-Geraghty contraction type maps in metric spaces}, Fixed Point Theory Appl. \textbf{2014:190} (2014), 1 -- 12]. Some examples are given to illustrate the obtained results and to show that these results are proper extensions of the existing ones. Then we apply the obtained theorem to study the existence of solutions to the nonlinear integral equation.

FIXED POINT THEOREMS USING (CLCS) PROPERTY IN COMPLEX VALUED $b$-METRIC SPACES
Authors: Verma Rohit Kumar
Published: April 2018

Abstract. Various common fixed point theorems have been proved for oneor two pair of mappings using either (CLR) property ([24]), or by takingone of the range-subspace closed. In this paper, we introduce the notion of(CLCS)-property i.e., “common limit converging in the range sub-space”. Using this property, we prove common fixed point theorems for two pairs ofweakly compatible mappings in complex valued b-metric spaces satisfying acollection of contractive conditions. Our notion is meaningful and valid because the required common fixed point will always lie on the range-subspace of the mapping-pair. We give some examples to show that if a mapping pair (f, g) of a closed complex valued b-metric space X satisfy the (CLRf ) property, then it is also (CLRg), and vice-versa.

Authors: Ibrahim Rabha W.
Published: April 2018

In this paper, we aim to introduce some geometric properties of analytic functions by utilizing the concept of fractional entropy in a complex domain. We extend the fractional entropy, type Tsallis entropy in the complex z-plane, by using some analytic functions. Established by this diffusion,we state specic new classes of analytic functions (type Schwarz function). Other geometric properties are validated in the sequel. Our development is completed by the Euler form Lemma and Jack Lemma.

Authors: Indra Astutik Ika Ratna , Rosid Mochamad Alfan
Published: April 2018

AbstractTeaching plan is one of the obligations that must be made by lecturer before conducting any lecture because teaching plan will be used by lecturer as a reference in determining Learning Outcomes (LO) and providing recovery materials in each semester. Unfortunately, there are still many existing teaching plans in College which are still manually developed. Thus, they may undermine head courses and Institute of Educational Development Study and Majors to perform learning monitoring and evaluation in the department.This research developes a system application which facilitates lecturer in managing teaching plan recovery and facilitates the Institute of Educational Development Study and Majors in evaluating the learning effectiveness, the suitability of the teaching journal and the achievement of Learning Outcomes. The system is developed using FAST method (Framework for the Application of System Thinking) and designed using a responsive Twitter Bootstrap template. The information generated system can also be used to support the cccreditation of Program Study. The testing process in this system uses blackbox testing to check the stability of the deployed system. The result of the test shows that all functions in the system runs perfectly, and the lecturers are more easily managing the Teaching plan, and the head of the Department can evaluate the suitability of the Teaching plan with teaching journal.

Authors: Fitrianingsih Elis , Setyati Endang , Zaman Luqman
Published: April 2018

Facial feature extraction is the process of searching for features of facial components such as eyes, nose, mouth and other parts of human facial features. Facial feature extraction is essential for initializing processing techniques such as face tracking, facial expression recognition or face shape recognition. Among all facial features, eye area detection is important because of the detection and localization of the eye. The location of all other facial features can be identified. This study describes automated algorithms for feature extraction of eyes and mouth. The data takes form of video, then converted into a sequence of images through frame extraction process. From the sequence of images, feature extraction is based on the morphology of the eyes and mouth using Neural Network Backpropagation method. After feature extraction of the eye and mouth is completed, the result of the feature extraction will later be used to detect a person’s drowsiness, being useful for other research.

In segment-based clustering, the paragraphs selection as a dataset in the clustering process has a very important role. This is because the paragraph used as the dataset can affect the clustering result. This research uses paragraph selection using feature-based method which aims to optimize the clustering process conducted in the previous research. Based on the evaluation results using Silhouette Coefficient and Sum Square Errors evaluation methods to find the proper k value, it is found that with the utilization of Feature-based method, better results can be acquire compared to the evaluation result from the previous research.
ROI Based Post Image Quality Assessment Technique on Multiple Localized Filtering Method On Kinect HD Sensor Mobile Robot
Authors: Wardani Kholilatul , Kurniawan Aditya
Published: April 2018

The ROI (Region of Interest) Image Quality Assessment is an image quality assessment model based on the SSI (Structural Similarity Index) index used in the specific image region desired to be assessed. Output assessmen value used by this image assessment model is 1 which means identical and -1 which means not identical. Assessment model of ROI Quality Assessment in this research is used to measure image quality on Kinect sensor capture result used in Mobile HD Robot after applied Multiple Localized Filtering Technique. The filter is applied to each capture sensor depth result on Kinect, with the aim to eliminate structural noise that occurs in the Kinect sensor. Assessment is done by comparing image quality before filter and after filter applied to certain region. The kinect sensor will be conditioned to capture a square black object measuring 10cm x 10cm perpendicular to a homogeneous background (white with RGB code 255,255,255). The results of kinect sensor data will be taken through EWRF 3022 by visual basic 6.0 program periodically 10 times each session with frequency 1 time per minute. The results of this trial show the same similar index (value 1: identical) in the luminance, contrast, and structural section of the edge region or edge region of the specimen. The value indicates that the Multiple Localized Filtering Technique applied to the noise generated by the Kinect sensor, based on the ROI Image Quality Assessment model has no effect on the image quality generated by the sensor.
Application Kohonen Network and Fuzzy C Means for Clustering Airports Based on Frequency of Flight
Authors: Rahmalia Dinita , Herlambang Teguh
Published: April 2018

In Indonesia, the demands of air tranportation for reaching destination increase rapidly. Based on the flight schedule in airports spreading in Indonesia, the airports have different flight demand rate so that it requires clustering. This research will use two methods for clustering : kohonen network and Fuzzy C Means (FCM).Kohonen network is the type neural network which uses unsupervised training.Kohonen network uses weight vectors for training while FCM uses degree of membership. Both kohonen network and FCM, inputs are represented by the number of departure and arrival of airline in one day. For kohonen network, we update weight matrices so that minimizing the sum of optimum euclidean distance. For FCM, we update degrees of membership so that minimizing the objective function value.From the simulations, we can cluster the airports based on the number of departure and arrival of airline.
