Published: July 2017

Over the period of time, human race has evolved and till date the development is going on. There is continuous civilization and change in life style of human being. Due to these changes in life style, human being is constantly struggling against the changing environmental conditions to maintain optimum health and vigor throughout the life. These changes have lead to increase in the disease burden in the society. Juvenile Diabetes is also such condition which is going to increase day by day in children. Children are the most vulnerable community in society. Juvenile diabetes (Insulin Dependent Diabetes Mellitus – IDDM/ Type 1 DM / T1DM) is the most common endocrine/metabolic disorder of childhood and adolescence. The high prevalence data of Juvenile Diabetes is also alarming. Globally, the incidence of Type 1 DM is increasing in children and youth by about 3% per annum. It is characterized by deficient insulin production and requires daily parenteral administration of insulin, otherwise may prove fatal. The cause of type 1 diabetes is not known and it is not preventable with current knowledge. So a survey of 50 diagnosed juvenile diabetes patients in Jamnagar city of Gujarat state was conducted. With this survey study an effort has been done to find out some contributory factors in the manifestation of the disease from an Ayurvedic perspective.

Authors: Vidyashree Vidyashree , Shankar Gowda , M. S. Doddamani
Published: July 2017

Pishti Kalpana is one of the Kharaliya Kalpanas of Rasashastra which brings the heat sensitive substances to micro particle level without applying the heat for better therapeutic efficacy and is considered as Sukshma as Bhasma. In Rasa texts it is said that Marana of Ratna and Uparatna are not worthwhile hence, Pishti Kalpana is advocated. There is no direct reference for the Siddhilakshana of Pishti, but our Acharyas has mentioned that Pishti is a Anagnisidhdha Bhasma i.e. Pishti should be Bhasmavat, so the parameters mentioned for quality control of Bhasma in ancient text are applicable for assessing the Siddhi Lakshanas of Pishti. So an attempt has been made to study analytically Sidddhilaxana of Pishti by both ancient and modern parameters with special reference to Akika Pishti. Akika is one of the semiprecious gems grouped under the Paradadi Varga, Uparatna Varga and Spatika Varga Ratna. In present study Pishti was prepared as per pharmacopeal standards and subjected to both ancient and modern tests to analyze them viz. Pishtivarna, Mrudutva and Slakshanatva, Rekhapurnata, Varitara, Nirdhooma, Unama and Nischandratva tests according to classics and according to modern parameters, organoleptic tests, physio chemical like LOD, pH, ash values, instrumental analysis like XRD , SEM-EDAX and particle size.

Ayurveda is a science of life with a holistic approach to health and personalized medicine. It is a system of traditional medicine developed during antiquity and the medicinal period and as such as comparable to modern system of medicine. Ayurveda gives us a model to look at each individual as a unique make up of Tridosha and to thereby design treatment protocols. Unfortunately, due to lack of scientific validation in various concepts like Tridosha, Prakruti, Mahabhuta, Guna and its affect on body. Hence evidence-based research as highly needed for global recognition and acceptance of Ayurveda, which need further advancements in vitro study. The present review highlights to improve the fundamental principles, drugs, pharmaceuticals and clinical research in Ayurveda through cell line study. In vitro studies permit a species-specific, simpler, convenient and more detailed analysis that can be done with the whole organism. This attempt will certainly encourage to researchers to work on cell line for the development and promotion of Ayurveda.
Role of Uttarabasti in the management of Functional Bladder Outlet Obstruction: A Case Study
Authors: Patel Jaimin R.
Published: July 2017

Bladder outlet obstruction (BOO) produces compression or resistance upon the bladder outflow channel at any location from the bladder neck to urethral meatus. It may be induced by specific functional and anatomic causes. Functional obstruction may be caused by detrusor-sphincter dyssynergia (DSD) and anatomic obstruction most commonly from benign prostatic enlargement (BPH) or urethral stricture. Obstructive symptoms include hesitancy, sensation of incomplete bladder emptying, diminished urinary stream. The combination of PVR, urinary flow measures, and symptom appraisal has been generally accepted as the initial screening and evaluation paradigm for BOO. In, Ayurveda, BOO is similar to Mutraghata means obstruction in the urine flow. Uttarbasti is the prime treatment of Mutraghata. Present case is diagnosed as a functional bladder outlet obstruction (BOO) on the basis of symptoms, normal reports of USG and ascending urethrogram and diminished flow of urine in Uroflowmetry. Total 7 Uttarbasti with 50ml Sahcharadi Tailam was given along with Rasayana and Mutraghatahara medicine. Patient has complete relief in his obstructive urine complains and has normal urine flow without taking Tab. AFDURA after 7 years. And also improvement appear in Uroflowmetry.
Variant origin of Common Interosseous Artery from Brachial Artery
Authors: Subbannavar Pralhad D.
Published: July 2017

Acharya Sushruta has emphasized the method and importance of dissection to study anatomy practically. Perfect knowledge of anatomy is vital for practicing surgeons and hence the training of dissecting the dead body was considered as mandatory for surgeons. Though dissection techniques may give the perception of the structure of organs, the pervading and subtle consciousness in the body can be experienced with the eyes of knowledge and penance only. Though the standard anatomy is defined based on statistical inferences on comparing large number of subjects, individual variations and exceptional structural specialties tend to occur quite frequently. Proper recording and publication of such instances would strengthen the knowledge base of the science. Knowledge regarding arterial variations of upper limb is important for surgeons and orthopedicians as they are commonly involved in invasive procedures. We report a case ofvariant origin of right common interosseous artery from brachial artery in cubital fossa. It followed a normal course after the origin.

Da corte ao Estado Novo: singularidades em Mozart e Villa-Lobos
Authors: Matias Carlos Dos Passos Paulo , Zanelatto João Henrique
Published: July 2017

Quase um século e meio separa o nascimento de Mozart do nascimento de Villa-Lobos. Na tragédia de Bajazzo, Norbert Elias nos mostra, com maestria, o drama da vida de um músico na corte de Salzburgo. Sua análise sociológica busca compreender um pouco da vida e da obra de Mozart, desde sua formação musical, proporcionada pelo pai, até o rompimento do músico com a “sua” corte e sua corajosa busca pela independência artística em Viena. A tragédia villalobiana é outra, mas não menos dramática. Villa-Lobos não foi músico de uma corte absolutista, como foi Mozart; não sofreu pensando em como sair de serviçal da corte para tornar-se livre, um músico do mundo. No entanto, os dois sofreram a angústia de buscar um lugar na sociedade de suas épocas. Mozart queria sair do julgo do mecenas, e o fez; Villa-Lobos queria ser empregado do mecenas/governo, e o fez. Para compreender e retomar este debate, trabalhou-se com as fontes de diálogo os autores Norbert Elias, Vasco Mariz, Bruno Kieffer, José Miguel Wisnik, Anália Cherñavsky e Arnaldo Contier.

Uninterruptible Energy Production in Standalone Power Systems for Telecommunications
Authors: E. F. F. Ribeiro  , A. J. Marques Cardoso  , C. Boccaletti
Published: July 2017

A continuously energy production is the most difficult and important feature to be guaranteed when designing a standalone power system for telecommunications. This paper focuses on a standalone power system for telecommunications already proposed in the literature, combining the most mature generators and technologies related to renewable energies and environment friendliness. It is important to know the operational problems, the best way to solve them and how to apply efficient maintenance. Reliability studies based on existent applications of renewable generators (some of them used in standalone power systems) help to know what to expect from their operational behaviour and to reduce time and costs in maintenance tasks. Notwithstanding their undoubted importance, they are not much recognised in literature, yet. The paper presents a brief review based on the few reliability reports about wind and photovoltaic systems available in the literature. Contributions and important aspects are discussed having in mind all the obstacles to achieve an uninterruptible power supply.

Concept for Optimization and Simulation of renewable energy parks with desalination
Authors: D. Buschert  , B. Bitzer
Published: July 2017

This paper is about the concept of the combination of renewable energy parks and water desalination. During the energy production a lot of waste heat is produced which is in the majority of cases unused. The needed (waste) heat for the water desalination unit can be generated with biomass power plants, geo thermal or solar power. So the idea is to use this unused energy to convert saltwater into freshwater. This water can be used to irrigate fields or to produce common products. The advantage is that the produced water and energy can be used independent from each other. The current project is about the optimization between the water desalination unit from the company Terrawater [5] and the produced waste heat from a renewable energy source. At first there will be coded a simulation programme for a physical – mathematical model. Furthermore a control programme will be written which works together with the simulation programme to control the heat flow volume from the power plant or heat generator to the desalination unit to get the best performance and a best amount of freshwater. During the simulation process a lot of different aspects have to be regarded and they have to be included in the control programme.

A Control Circuit Small Wind Turbines with Low Harmonic Distortion and Improved Power Factor
Authors: O. Carranza  , E. Figueres  , G. Garcerá  , L. G. González
Published: July 2017

This paper presents the application of average current mode control to reduce the THDi and increase the PF in a Three-Phase Boost Rectifier driving a small wind turbine. It is used as input stage of small wind turbines with permanent magnet synchronous generators operating at variable speed. The Boost Rectifier´s output is connected to an inverter which feeds the energy to a distribution power grid. The operation in discontinuous conduction mode allows significantly reducing the Total Harmonic Distortion of the current in the small wind turbine. However, it is necessary to add an input filter so that the switching ripple doesn´t arrive to the small wind turbine. It is evaluated the convenience of the current sensors placement in the DC side of the rectifier or at the output of the generator. The results demonstrate that it is better to place the sensors in the output of the generator, because it is achieved smaller THDi and higher PF.

The main point of such a rotor construction is the design of the flux barriers because of its direct connection with the saliency of the machine. The performance analysis is derived from the results of a transient 2D-finite-element method with a direct coupled electrical circuit. Furthermore an optimized rotor design results in an elementary reduction of the supplementary losses caused by the higher harmonics.
Performance analysis of three-phase PWM rectifiers for high power quality applications
Authors: J. A. A. Caseiro  , A. M. S. Mendes
Published: July 2017

New power quality issues have brought new concerns about how the electrical devices connected to the mains behave and how their behaviour affects the mains quality and, consequently, other energy consumers. In result of these recent concerns, various new standards were made to limit the harmonic pollution that each device may produce. Diode rectifiers are one of the main polluters, not complying with these standards. The necessity for alternatives reaffirmed PWM rectifiers as a viable alternative. PWM additional capabilities as unity power factor and energy regeneration are other advantages that can be decisive in certain applications. This paper compares diode and PWM rectifiers. It analyses the performance of these systems and explores the PWM systems’ new capabilities. A Matlab/Simulink model has been made to allow the comparison. Simulation results are then verified by laboratorial implementation of the model. Simulation and experimental results are presented and commented.

OBJECTIVE To evaluate the feasibility of laparoscopy versus exploratory laparotomy for the diagnosis of specific lesions in dogs with suspected gastrointestinal obstruction.

DESIGN Controlled trial.

ANIMALS 16 client-owned dogs with physical and radiographic findings consistent with gastrointestinal obstruction.

PROCEDURES Single-incision laparoscopy with intracorporeal and extracorporeal examination of the gastrointestinal tract was performed by 1 surgeon. Immediately afterward, exploratory laparotomy was performed by a second surgeon. Accessibility and gross appearance of organs, surgical diagnoses, incision lengths, procedure duration, and complications were compared between diagnostic techniques.

RESULTS Mean (95% confidence interval) incision length was 4.9 cm (3.9 to 5.9 cm) for laparoscopy and 16.4 cm (14.0 to 18.7 cm) for exploratory laparotomy. Mean (95% confidence interval) procedure duration was 36.8 minutes (31.6 to 41.2 minutes) and 12.8 minutes (11.4 to 14.3 minutes), respectively. Diagnoses of the cause of obstruction were the same with both methods. In 13 dogs, the laparoscopic examination was successfully completed, and in the other 3, it was incomplete. In 4 dogs in which laparoscopy was successful, conversion to exploratory laparotomy or considerable extension of the laparoscopic incision would have been required to allow subsequent surgical treatment of identified lesions. No dogs developed major complications, and minor complication rates were similar between procedures.

CONCLUSIONS AND CLINICAL RELEVANCE Laparoscopy was feasible and clinically applicable in dogs with suspected gastrointestinal obstruction. Careful patient selection and liberal criteria for conversion to an open surgical approach are recommended when laparoscopy is considered for the diagnosis of gastrointestinal lesions in dogs.

OBJECTIVE To define learning curves for fourth-year veterinary students performing ovariohysterectomy procedures in dogs and cats and castration in dogs.

DESIGN Retrospective study.

SAMPLE 3,196 ovariohysterectomies or castrations performed in dogs and cats by 88 veterinary students during a spay-neuter surgery and animal shelter rotation (n = 3,056) or by 1 experienced general practitioner (n = 140).

PROCEDURES Data collected from medical records included patient signalment, type and duration of procedure, and sequence (by date and time) of the procedure within a list of procedures of the same type generated for each student. For each procedure type, geometric mean surgery time and 95% confidence intervals were determined for each number of surgeries completed by ≥ 10 students. Median surgery times for the same procedure types were determined for the experienced practitioner. The learning curve for each procedure was modeled with nonlinear (3-factor exponential equation with a nonzero asymptote) and linear regression. For each procedure, the asymptote (optimal surgery time) for students was compared with the experienced practitioner's median surgery time.

RESULTS 2,945 surgeries (mean, 33/student) performed by ≥ 10 students were analyzed. Surgery time decreased in a nonlinear manner as student experience increased for castration of adult or pediatric dogs and ovariohysterectomy of pediatric dogs and adult or pediatric cats. Surgery time decreased in a linear manner as experience increased for ovariohysterectomy of adult dogs.

CONCLUSIONS AND CLINICAL RELEVANCE To the authors' knowledge, this was the first study to map surgery times for common surgical procedures consecutively performed by veterinary students. Results clearly indicated the value of repetition to improve surgical skills (as measured by surgery time) during a 3-week period.

«-Eu que fiz!» A produção de curtas-metragens como estratégia tecnológica de autoria, aprendizagem e inclusão (maio 2016)
Authors: Lindenmeyer Simone , Schmidt Madebe , Matias Flávia , Bez Maria Rosangela
Published: July 2017

Este relato aborda uma prática pedagógica que utilizou a produção de curtas-metragens como estratégia de autoria, aprendizagem e inclusão. O projeto ocorreu no ano de dois mil e quinze, com dez alunos do quarto e quinto anos que frequentavam o chamado Laboratório de Aprendizagem e também alunos com deficiência, que faziam e fazem parte ainda hoje do Atendimento Educacional Especializado de uma escola da cidade de Novo Hamburgo, região metropolitana de Porto Alegre, Rio Grande do Sul/Brasil. Propõe uma reflexão e traz visibilidade às diferenças daqueles que chamamos de alunos com dificuldades de aprendizagem e dos alunos com deficiência. Existem diferentes maneiras de se olhar as diferenças que emergem no ambiente escolar. A proposta é de que o leitor experimente contemplar as potencialidades desses sujeitos e não as suas dificuldades ou a sua deficiência; que coloque as lentes da criação, da autoria e do prazer que se constrói e circula a nível das individualidades como da coletividade a partir deste artefato tecnológico-criativo. A produção de curtas-metragens surge como uma ferramenta para demonstrar como o protagonismo do aluno pode ser fortalecido por meio da autoria.
Process of Change in Pain-Related Fear: Clinical Insights From a Single Case Report of Persistent Back Pain Managed With Cognitive Functional Therapy

Published: July 2017

Study Design

Single case report with repeated measures over 18 months.

Background

Management of persistent low back pain (PLBP) associated with high pain-related fear is complex. This case report aims to provide clinicians with insight into the process of change in a person with PLBP and high bending-related fear, who was managed with an individualized behavioral approach of cognitive functional therapy.

Case Description

A retired manual worker with PLBP believed that his spine was degenerating, that bending would hurt him, and that avoidance was the only form of pain control. At baseline, he presented high levels of pain-related fear on the Tampa Scale of Kinesiophobia (score, 47/68) and a high-risk profile on the Örebro Musculoskeletal Pain Questionnaire (score, 61/100). Unhelpful beliefs and behaviors led to a vicious cycle of fear and disengagement from valued life activities. Guided behavioral experiments were used to challenge his thoughts and protective responses, indicating that his behavior was modifiable and the pain controllable. Using a multidimensional clinical-reasoning framework, cognitive functional therapy management was tailored to target key drivers of PLBP and delivered over 6 sessions in a 3-month period.

Outcomes

Over an 18-month clinical journey, he demonstrated improvements in bending-related fear, pain expectancy, and pain experience, and substantial changes in pain-related fear (Tampa Scale of Kinesiophobia: 33/68; change, −14 points) and risk profile (Örebro Musculoskeletal Pain Questionnaire: 36/100; change, −25 points). Clinical interviews at 6 and 18 months revealed positive changes in mindset, understanding of pain, perceived pain control, and behavioral responses to pain.

Discussion

This case report provides clinicians with an insight to using a multidimensional clinical-reasoning framework to identify and target the key drivers of the disorder, and to using cognitive functional therapy to address unhelpful psychological and behavioral responses to pain in a person with PLBP and high pain-related fear.
