Práticas de gestão da informação e inovação aberta em um pólo tecnológico brasileiro
Authors: Cândido Ana Clara , Vale Mariene Alves do
Published: March 2019

Resumo As inovações de produtos e serviços eram desenvolvidas, sobretudo, internamente nas organizações até a propagação do modelo de Inovação Aberta no ambiente de negócios. Os processos colaborativos de inovação acontecem a partir da interação entre atores distintos: fornecedores, clientes, instituições de ensino e pesquisa e o governo. Nesse cenário, a informação precisa ser tratada adequadamente por meio da gestão estratégica da informação. Dos procedimentos metodológicos, trata-se de um estudo exploratório e descritivo, quali-quantitativo que buscou conhecer como as empresas do polo tecnológico de Florianópolis gerem a informação e realizam suas práticas de inovação. Os resultados evidenciam a ausência de setores e profissionais dedicados exclusivamente à gestão da informação. As principais fontes de informação são as mídias digitais e os eventos promovidos por entidades representativas. Existem procedimentos padronizados, porém não formalizados, para organizar, armazenar, distribuir e utilizar a informação. A inovação, maioritariamente, é resultado da contribuição dos próprios colaboradores, assim como dos consumidores finais e dos fornecedores. O principal motivador para o investimento em inovação é a necessidade de manter-se à frente dos concorrentes, além da redução de custos e o aumento do valor percebido pelos clientes, também contribuindo para o aprendizado dos profissionais envolvidos.

Published: March 2019

Abstract Aim This study aimed to investigate the relative influence of climate (temperature and precipitation) and land use on limnological features of 30 floodplain lakes in the Araguaia River, in Central Brazil, an important river that drains in the Brazilian Cerrado. Methods The lakes were sampled in one same period, at a large spatial scale (900 km along the river) covering climate and landscape variability. For decomposing the relative importance of land use and climate, we used the RDA and partitioning variance techniques. Results The lakes presented limnological gradient along the floodplain; in general, the lakes presented low transparency, nutrients concentrations (total nitrogen and total phosphorus) and oxygen saturation. The water pH was considered weakly acidic. Considering land use in Araguaia river basin, lakes in downstream presented more remnant vegetation and lakes in upstream presented more livestock and agriculture soil use. The climate conditions were the most important in explaining the variation in limnological characteristics of the lakes, while the individual analysis of limnological variables showed that land use was important to explain to the pH and transparency of the water. Conclusions Finally, this study showed the importance of investigating regional climatic attributes and land use information to explain the limnological characterization of floodplain lakes. Thus, it highlights the importance of the possible impacts of global climate change on limnological conditions.
Size Dependent Elastic and Thermophysical Properties of Zinc Oxide Nanowires
Authors: Tripathi Sudhanshu , Agarwal Rekha , Singh Devraj
Published: March 2019

Size dependent characterisation is important for applications in nanoelectromechanical systems (NEMS), nanogenerators, biosensors and other related areas at higher temperature regimes. In this paper we have computed elastic, mechanical, thermal and ultrasonic properties of zinc oxide nanowires (ZnO-NWs) of different diameters at high temperatures. The higher order elastic constants of ZnO-NWs were computed using a simple interaction potential model. The mechanical properties such as bulk modulus, Young’s modulus, shear modulus and Poisson’s ratio were determined based on the formulated elastic constants. Various ultrasonic parameters such as ultrasonic wave velocities, ultrasonic Grüneisen parameter and ultrasonic attenuation were obtained with the help of elastic constants and density. The temperature dependent ultrasonic wave velocities propagating along the length of the nanowire at different orientations were calculated using elastic constants to determine anisotropic behaviour. The diameter dependent ultrasonic losses and thermal characteristics of ZnO-NWs were also determined. The ultrasonic attenuation due to the phonon-viscosity mechanism is predominant for the total ultrasonic attenuation for ZnO-NWs. The correlation among the ultrasonic parameters, thermal conductivity and size of ZnO-NWs is established leading to potential industrial applications.
Trabajo docente y políticas de evaluación externa en Colombia y Brasil
Authors: Remolina Caviedes Juan Francisco
Published: March 2019

El presente artículo tiene como objetivo investigar y analizar críticamente en qué medida las políticas de evaluación externa implementadas en Colombia y Brasil influyen en la configuración del trabajo docente. Con base en este interés, nos referimos a las percepciones docentes sobre la materialización de estas políticas en ambas realidades, adoptando la perspectiva de los Estudios Históricos Comparados en el ámbito de la matriz teórico-metodológica del Materialismo Histórico-Dialéctico. De tal manera, se realizaron entrevistas semi-dirigidas con un total de 30 docentes que actuaban en diferentes áreas de seis escuelas públicas de Colombia y Brasil. Los resultados evidenciaron que las políticas educacionales gestadas y diseminadas por organismos multilaterales al servicio del capital, como el Banco Mundial, median en la configuración de las políticas educativas de ambos países por intermedio de la ideología gestiocrática, contribuyendo progresivamente con la precarización del trabajo docente.
Condiciones de posibilidad psicosociales de una estudiante de psicología con enfermedad motora de origen cerebral
Authors: Campos Sanchez Marcela , Pedraza Cardozo Alba Paola
Published: March 2019

La investigación se llevó a cabo en el Programa de Psicología de la Corporación Universitaria Minuto de Dios – UNIMINUTO – Sede Principal. Tuvo como objetivo  comprender las condiciones de posibilidad psicosociales que estuvieron presentes en el desarrollo del proceso educativo de una estudiante de psicología con enfermedad motora de origen cerebral, tipo atetósica. En esta investigación la estudiante cumplió doble rol al ser el sujeto del estudio de caso y asistente de investigación. La metodología de la investigación contempló la revisión de investigaciones y sistematizaciones de casos similares, la reconstrucción autobiográfica de la experiencia educativa en educación superior, y la realización de entrevistas a los actores significativos de la experiencia. A partir del análisis de las prácticas discursivas desde Foucault se encontraron tres condiciones de posibilidad para desarrollar procesos para la educación para la diversidad: (a) disolver la correlación entre parálisis cerebral y discapacidad cognitiva, (b) cuestionar el saber-hacer especializado sobre la discapacidad, y (c) superar el miedo a relacionarse con los cuerpos diversos.
Las representaciones de la identidad del estudiante: perspectivas de dos comunidades lingüístico-culturales
Authors: Torres Oscar
Published: March 2019

Nuestro interés investigativo surge de la reflexión sobre las dificultades que los estudiantes experimentan cuando se vinculan a otras instituciones universitarias en el extranjero durante un programa de intercambio. Consideramos que esta problemática se puede explorar a partir del estudio lingüístico-discursivo de las representaciones identitarias del estudiante en términos de acciones, cualidades y su relación con el entorno. Para ello, nos dimos como objetivo analizar y comparar las representaciones identitarias del estudiante en dos comunidades lingüístico-culturales distintas, la primera conformada por estudiantes colombianos y la segunda por estudiantes franceses que se forman como profesores de lenguas extranjeras. En primer lugar, se dará cuenta de la metodología que estructuró nuestra investigación, la cual se fundamenta en la teoría de la Semántica de los Posibles Argumentativos, luego se expone el análisis de las representaciones del estudiante que fueron obtenidas, en diccionarios y en los discursos de los estudiantes, a nivel del núcleo, es decir a partir de las propiedades esenciales que caracterizan dicho término. Finalmente se estableció la comparación entre el discurso lexicográfico y el de los estudiantes con el fin de identificar los elementos compartidos que pueden constituir la base de un diálogo pedagógico intercultural.
Pertinencia y actualidad de la pedagogía amigoniana
Authors: Corredor Vargas Luis Eduardo , Zuluaga Mesa David Esteban
Published: March 2019

Este artículo de revisión presenta un rastreo de la producción escrita en torno al desarrollo teórico de la pedagogía amigoniana. El proceso metodológico implicó, en un primer momento, la identificación de fuentes referentes al amigonianismo en general; así se obtuvieron 78 referencias (13 libros, 32 artículos, 22 actas de congresos, 8 boletines informativos, 2 tesis doctorales y 1 cartilla). Luego se hizo una revisión en la que se seleccionó únicamente el material que tuviera relación con la pedagogía amigoniana; como resultado se descartaron 22 fuentes y se conservaron 56. Estas se leyeron a profundidad y se identificó cómo se aborda en ellas puntualmente el campo pedagógico amigoniano en torno a su identidad, carisma, espiritualidad, principios, valores, actitudes y perfil del educador amigoniano. Se encontró que solo 40 de ellas desarrollan el tema que nos ocupa, por lo tanto se descartaron las 16 restantes. El ejercicio de revisión permitió identificar los pilares de la pedagogía amigoniana, los retos que debe atender en el mundo contemporáneo, sus principales discusiones y, sobre todo, indagar acerca de su pertinencia y su actualidad. El artículo concluye indicando que la finalidad de la pedagogía amigoniana es reflexionar, investigar, sistematizar y socializar su saber pedagógico, direccionando sus esfuerzos a la formación de agentes sociales, buscando transformaciones benéficas a través de su identidad y carisma como garante de los derechos fundamentales de las personas.

La publicación de artículos en revistas científicas o académicas ha alcanzado gran preponderancia en las comunidades académicas y en los indicadores de calidad, principalmente de las instituciones universitarias. Presentamos las razones que llevaron a un grupo de docentes de inglés a enviar sus trabajos para publicar en una revista editada en Colombia. La información se recopiló mediante un cuestionario utilizado en un estudio de caso exploratorio. Analizamos los resultados desde la perspectiva de las lógicas del razonamiento científico-social implícitas en las opiniones de los autores y señalamos algunas implicaciones para la circulación de distintas voces en revistas editadas en países periféricos.
Profesores/as que marcan la diferencia. Experiencias escolares en contextos históricamente silenciados
Authors: Pons Bonals Leticia , Espinosa Torres Iván de Jesús , Contreras García Jesika Berenice , Estrada Soto Danae
Published: March 2019

El objetivo de este artículo es destacar la importancia que adquiere el profesorado en la construcción de experiencias escolares que marcan la vida de sus estudiantes en contextos diversos culturalmente en los que prevalecen procesos de exclusión y discriminación. Lo que se expone es producto del análisis de los resultados obtenidos en tres investigaciones recientes realizadas desde un enfoque interpretativo, haciendo uso de métodos biográficos que rescatan las experiencias vividas por estudiantes indígenas, por mujeres que han logrado posicionarse en el ámbito académico y por parejas lésbicas-gay-trans que han decidido conformar una familia. Como resultado del análisis de las narrativas que se presentan en las tres investigaciones se descubre una escuela de corte tradicional, en la que existe discriminación, en la que se silencian las voces de aquellos que no se ajustan a la norma. Pero también se advierte en esta escuela la presencia de un/a profesor/a que establece el cambio y hace posible la construcción de experiencias escolares significativas. Se concluye que la relación intercultural y afectiva que se establece entre profesor-estudiante marca esta diferencia.
Estado de la cuestión de los centros y programas de escritura de Latinoamérica
Authors: Molina-Natera Violeta , López-Gil Karen Shirley
Published: March 2019

Esta investigación buscaba identificar las teorías, prácticas y procesos de gestión de los centros y programas de escritura en universidades de América Latina. Para ello, se propuso un estudio exploratorio que tuvo como principal instrumento un cuestionario en línea. Participaron en la investigación 23 directores de centros y programas de escritura de la región. Los resultados evidencian una variedad de programas muy jóvenes en su conformación. La escritura empieza a incluirse en las agendas programáticas de las universidades latinoamericanas, teniendo en cuenta el respaldo institucional conferido a estas iniciativas en los últimos 10 años. Respecto a los fundamentos teóricos, se encontró una diversidad de enfoques y posturas teóricas que configuran estos centros y programas de forma distinta a sus antecesores en Norteamérica. Los programas incorporan prácticas que tienen que ver, en su mayoría, con el acompañamiento individual a través de tutorías o con el trabajo colaborativo entre docentes de lengua y docentes de otras disciplinas. La gestión administrativa plantea un desafío especial en cuanto a la medición del impacto de los programas. Los directores asumen una serie de funciones que requieren de una capacitación integral en tareas administrativas, con la cual no se cuenta aún en la región. Estos resultados evidencian la necesidad de fortalecer los procesos de gestión de estas iniciativas y la pertinencia de consolidar un campo propio de investigación.
Papel del docente y de la escuela en el fortalecimiento de los Proyectos de Vida Alternativos (PVA)
Authors: García-Yepes Karen
Published: March 2019

Este artículo surge de una tesis doctoral, cuyo objetivo es analizar el papel deldocente y del sistema educativo en el fortalecimiento de los proyectos de vida alternativos (PVA) de los estudiantes. Como metodología se recurrió a la investigación de tipo cualitativo, y la técnica de recolección de información fue la entrevista en profundidad, donde participaron docentes y directivos de una institución educativa colombiana. Con respecto a los resultados, se evidencia que los procesos educativos en contextos vulnerables están condicionados por las limitaciones sociales y económicas del entorno, así como por las características del sistema educativo tradicional. En cuanto a las conclusiones, se plantea que el papel del docente y del sistema educativo consiste en aportar prácticas pedagógicas innovadoras como alternativa a la visión instrumental de la educación. Estas estrategias deben orientarse hacia el impacto en las mentalidades del estudiante y a la interacción entre el aprendizaje de conocimientos y habilidades para la vida, con el fin de incidir de manera significativa en la construcción de los PVA.

Ética y formación de investigadores: la importancia de las virtudes y la sabiduría práctica
Authors: Cuadros-Contreras Raúl
Published: March 2019

En el artículo se defiende la importancia de los modelos o enfoques de pensamiento ético como marcos indispensables para ampliar el horizonte de sentido de la ética aplicada, más si se trata de promover la formación ética de investigadores. Se exponen brevemente los dos enfoques predominantes del pensamiento ético en nuestro tiempo (consecuencialismo y deontologismo), y se señalan algunas de sus limitaciones. Posteriormente se reivindica un enfoque antiguo pero cada vez más vigente: el enfoque de las virtudes, que más que centrarse en principios o en el cálculo de las consecuencias, concede primacía al ejercicio de la sabiduría práctica anclado en la formación del carácter. Al final se insiste en la bondad de un enfoque como este, que nos separa de una visión meramente defensiva de la ética de la investigación, a la que se opone una concepción afirmativa, que vincula las decisiones éticas con la busca de la realización personal del investigador y de los sujetos y comunidades con los que investiga.

Feather colour affect aggressive behaviour of chickens with same genotype on dominant white (I) locus v1
Authors: Nie Changsheng , Ban Liping , Ning Zhonghua , Qu Lujiang
Published: March 2019

Aggression in chickens is a serious economic and welfare issue. Pigmentation traits have been well documented to be associated with animal behaviour. Previous studies have shown that chicken pecking behaviour is related to the feather colour and premelanosome protein 17 (PMEL17) is one of the candidate genes. In the present study, we performed a genotypic and phenotypic association analysis between chicken plumage colour (red and white) and aggressive behaviour in an F1 hybrid group, generated by crossing an autosome dominant white feather breed, White Leghorn (WL), and a red feathered breed, Rhode Island Red (RIR). In genetic theory, the progeny should all have white feathers since the WL are homozygous autosome dominant white. However, we found a few red-feathered female chickens. We compared aggressiveness between the red and white females to determine whether the feather colour alone affected the behaviour since the genetic background should be the same except for the feather colour. The aggressiveness was recorded 5 days after sex maturity at 26 weeks. Generally, white plumage hens showed significantly higher aggressiveness than the red ones did in chase, attack, peck, and threatening behaviour. We also detected three feather colour candidate genes, PMEL17, solute carrier family 45 member 2 (SLC45A2), and SRY-box 10 (SOX10) in determining the genetic foundation for the red and white feather colour in our hybrids population and there was no association between the three loci and the feather colour. Additional studies should be conducted to elucidate further the genetic or phenotypic mechanisms underlying the feather colours and the behaviour.

Application of Plants Extracts as Green Corrosion Inhibitors for Steel in Concrete - A review
Authors: Asmara Yuli Panca , Kurniawan Tedi , Sutjipto Agus Geter Edy , Jafar Jamiluddin
Published: March 2019

High requirements in protection of steel reinforcing bar (steel rebar) from corrosion are necessary since there are multi interaction of corrosive chemicals which cause early damage of concrete buildings. Corrosion of steel in concrete can destroy the concretes and reduce concrete strength. To protect rebar from corrosion, application of corrosion inhibitor is believed to have higher performance compared to other protection systems. To date, organic inhibitors have promising methods in steel rebar protection as they are environment-friendly, compatible with concrete, cost effective and applicable in any various concrete conditions. Thus, demands in using these inhibitors tend to increase significantly. This paper reviews the applications of green corrosion inhibitor specifically highlighted in protecting mechanisms, typical plants extracted, performance in corrosion protection, and classification of green corrosion inhibitors. The corrosion resistances of carbon steels in concrete protected by green inhibitors are in focus. As summary, it can be conﬁdently notified that green corrosion inhibitors for steel in concrete will have a prospect to be used as corrosion prevention in the future with further improvements.
Career Education Discourse: Promoting Student Employability in a University Career Center
Authors: Helens-Hart Rose
Published: March 2019

In 2016, Gallup reported 80 percent of recent U.S. college graduates who had visited career services offices (CSO) rated their engagement to be somewhat to very helpful. Quantitative reports such as this provide student views of CSOs, but neither address CSO staff’s perceptions of the value of their work nor the tools they use to assist students. Staff perceptions provide insight into how they communicate with students and align with emerging career education paradigms. Through in-depth interviews and participant observations, this study illuminates the communicative strategies used by CSO staff at a large U.S. Midwestern public university to support student employability. This study extends our theoretical understanding of career education and employability discourse, where staff engaged students’ assumptions about careers and provided opportunities for them to diversify knowledge about themselves and work to develop their career identities. Additionally, career education activities supported the development of students’ social capital and personal adaptability through staying positively focused and proactive in career exploration and job searches. Practical implications for this study are that employability discourse could (1) emphasize how institution-sponsored activities could increase student job seeker competitiveness, but also (2) instill a “no guarantees” academic culture where students are responsible for their employability.
Multiple Layers: Education Faculty Reflecting on Design-Based Research focused on Curricular Integration
Authors: Gallagher Tiffany L. , Fazio Xavier
Published: March 2019

What insights emerge through researcher reflections on a Design-Based Research (DBR) curricular integration project that contribute to the professional learning of education faculty/ researchers? To answer this question, two researchers captured their debriefing discussions and reflections after monthly meetings with participating teachers. The meetings familiarized the teachers with DBR methods and enhanced teachers’ understanding of integrating literacy and science instruction. Data were open coded, collapsed into sub-categories and interpretations were then clustered into three themes. The first theme is our acknowledgement of the layers that needed to be peeled back to understand teacher participants’ planning and assessment. The second theme is the realization that the teacher participants were novices with respect to understanding and practicing curricular integration. The final theme honors the value of DBR as a research and professional learning method. Findings are discussed in light of the scant literature that describes the experience of DBR educational researchers.

Published: March 2019

The aim of this study was to examine Turkish first-time and advanced supervisees’ supervisory relationship experiences. A phenomenological design was preferred for examining whether undergraduate- and graduate-level supervisees’ supervisory relationship experiences according to their professional developmental levels. The participants consisted of 27 supervisees enrolled in undergraduate, master’s, and doctoral programs in Counseling and Guidance at a public university in western Turkey. A semi-structured interview form was used to collect data. The results of content analysis demonstrated that according to first-time and advanced supervisees, the unchanged but definitive constructs of the supervisory relationship were supervisor’s facilitative and prescriptive interventions, sincere and nonjudgmental characteristics, constructive feedbacks; supervisee’s self-disclosure within supervision, anxiety in the early stages of the relationship and calmness in the further stages of the relationship, development of self-awareness and professional kills. The study findings were discussed and some implications are suggested.
New Insights on Young Peoples’ Motivation in Lower Secondary Education in Denmark
Authors: Pless Mette , Katznelson Noemi
Published: March 2019

In this article we explore and develop the understanding of young people’s motives for (non)participation in lower secondary education. Based on a two-year study dominated by qualitative and explorative methods, we combine a focus on young peoples’ motives and goal orientations with a socio-cultural (and social constructivist) understanding of motivation/learning (Wenger, 1998; Wertsch, 1994). This combination allows us to explore the dynamic complexity of pupils’ motives for participation in school and look into how motivation is produced in the interplay between individual goals and motives and the learning climate within the school context (Ames, 1992; Dowson & McInerney, 2003; Maehr & Zusho, 2009; Jackson, 2006; Lemos, 2001). In the article, we identify key motivational orientations as they unfold in the social and learning processes that take place in the learning contexts young people are part of. As a mean to synthesise and highlight the complexities at play we introduce a situated model that visualises our results.

Authors: Gupta Eshna , Prateek Shashi , Mani Poonam , Yadav Lalita , Tyagi Mamta , Singh Arushi
Published: March 2019

Background: The objective of the present study was to observe the efficacy of LNG-IUS in the treatment of heavy menstrual bleeding and dysmenorrhoea associated with adenomyosis.Methods: LNG-IUS was inserted in forty women between 20-50 years of age presenting with heavy menstrual bleeding and dysmenorrhoea associated with adenomyosis diagnosed on transvaginal ultrasonography and followed up after 1 month, 3 months and 6 months of insertion. Subjective assessment of menstrual blood loss was done by pictorial blood loss assessment chart and dysmenorrhoea was assessed on the basis of universal pain assessment tool and side effects were noted at each visit.Results: Mean patients’ age was between 31-40 years (72.5%) and the follow up duration was 6 months. Significant improvements in dysmenorrhea, HMB and haemoglobin levels were observed. There was no significant change in the uterine volume. The most common side effect was prolonged vaginal spotting (n=26, 65%) and pain abdomen (n=13, 32.5%). LNG-IUS expulsion was observed in 1 patient (n=1, 2.5%). 3 patients underwent hysterectomy (n=3, 7.5%). The overall success rate of LNG-IUS was 82.5%.Conclusions: The LNG-IUS appears to be an effective method in alleviating dysmenorrhoea and heavy menstrual bleeding associated with adenomyosis during 6 months of study. It may be a valuable long-term alternative for the treatment of adenomyosis in young and perimenopausal women and it is a good strategy to reduce the number of hysterectomies in women with adenomyosis.

Authors: Armo Meena , Khunte Vimal , Sainik Siddhi , Kanniga G. Rohini , Jatwar Nandani
Published: March 2019

Background: Cervical cancer is a leading cause of morbidity and mortality among rural women in India. Early screening has been shown to be the most effective measure to prevent the disease. However, lack of awareness, lack of infrastructure, social stigma and fear are barriers to cervical cancer screening. The study was undertaken to assess the knowledge and practice among rural women regarding cervical cancer and screening tests with the aim of helping health professionals to revise policies and practices.Methods: It was a cross-sectional questionnaire-based study, conducted from January 2018 to September 2018 in the Department of Obstetrics and Gynecology at Government Medical College Rajnandgaon. A tertiary care hospital located in the southwest Chhattisgarh. A total of 506 women aged 21-65 years were included and assessed. Qualitative data were presented as frequencies and percentages by using SPSS version 21.Results: Of the total 506 respondents, 15.41 % had heard of cervical cancer, while 8.1% about cervical cancer screening. Unfortunately, only 1.2% women were ever been screened by Pap test. Although importance of screening had been thoroughly explained to the respondents, despite the fact only 57.1% showed willingness to undergo cervical cancer screening in the future. However, 63.9%women having gynecological complains were significantly associated with better attitude towards future cervical cancer screening than women without having gynaecological complains.Conclusions: Awareness and practice of the screening for cervical cancer was very poor in the rural population as well as in health care providers. Hence intensive health education is the need of the hour to change the scenario.
When is the ideal time to remove cerclage in cases requiring cesarean hysterectomy for placenta accreta spectrum?
Authors: Ito Futa , Matsuzaki Shinya , Endo Masayuki , Kimura Tadashi
Published: March 2019

Placenta accreta spectrum (PAS) presents one of the highest risks to pregnancy and often requires a cesarean hysterectomy for management, but the challenges associated with this surgery often cause severe obstetric haemorrhaging and high rates of maternal morbidity. Shirodkar cerclage is usually performed in cases with cervical insufficiency, a short cervix with previous preterm birth, etc., to decrease the preterm birth rate. It is recommended that Shirodkar cerclage is removed when the patient approaches term, but the ideal timing of removal for patient for whom cesarean hysterectomy is planned is not clear. Here, authors present a case of PAS in whom Shirodkar cerclage that was difficult to remove at the timing of cesarean hysterectomy. After cesarean hysterectomy, the patient had a vaginal abscess and required antibiotic therapy for approximately two weeks. In the light of our case, authors discuss the timing of removal of cerclage in the cases of PAS.

Published: March 2019

Background: Anemia due to Iron deficiency is the commonest malnutrition disorder seen throughout the world and in India. It is also responsible for increased incidence of premature births, low birth weight babies and high perinatal mortality. Hence, the present study undertaken to assess efficacy and safety of injectable iron sucrose with oral ferrous ascorbate.Methods: 100 pregnant women, between gestational age 14 and 28 weeks were divided randomly into two groups i.e. group A consists of oral iron, a total of 200 mg of elemental iron per day, two 100mg iron tablets per day and group B consists of iron sucrose at the rate of 200mg on alternate OPD day. Informed consent was taken from each patient.Results: The percentage rise in hemoglobin at fourth and eighth weeks of treatment was statistically significant when compared to the baseline. Statistically significant rise in hemoglobin, PCV and ferritin levels were found at fourth and eighth weeks in IV group when compared to oral group.Conclusions: This study concluded that intravenous iron sucrose is safe and highly efficacious for the treatment of anemia in pregnancy. It restores iron stores more promptly. Iron sucrose therapy is more effective in achieving the optimum results, an increase in hemoglobin concentration, PCV levels and an increase in ferritin levels also. Therefore, it is a suitable alternative to oral iron with minimal side effects in those patients who cannot tolerate oral iron therapy.

Published: March 2019

Background: Accuracy of ventriculoperitoneal shunt with the development of frameless neuronavigation in the field neurosurgery has been validated in different parts of the world. The objective of this study was to compare the success of electromagnetic (EM) navigation system on ventriculoperitoneal (VP) shunt versus standard shunt placement in patients with hydrocephalus.

Methods: This randomized controlled trial was carried out in the Department of Neurosurgery, Multan. This study was approved by the Ethical Review Committee of Nishtar Hospital Multan. Study subjects were selected after an informed consent. Patients were grouped as (A) who received EM and (B) who received routine shunt surgery. Patients with shunts were followed up at the end of 3 months and post-operative CT was performed at the end of 3 months. Both groups were compared in terms of success by using chi-square test.

Results: Among 100 study cases, mean GCS was 12.30±1.85 (with minimum GCS was 9 while maximum was 15) and mean duration of hydrocephalus was noted to be 6.80±2.02 weeks. Forty five (45%) were presented with mild hydrocephalus while 55 (55%) presented with moderate hydrocephalus. Grade outcome (post-operative) was noted in 78 (78%) of our study cases, grade 2 in 18 (18%) while grade 3 (failure) was noted in only 4 (4%).

Conclusions: The usage of electromagnetic (EM) navigation on ventriculoperitoneal (VP) shunt is safe and reliable which is beneficial for optimal positioning and trajectory of ventricular catheters in adult patients with hydrocephalus.

Background: Diarrheal disorders along with dysentery constitute the second killer infections in childhood. In fact, more than half of the dysentery cases are recorded in children under 9 years of age. Shigella infection comprises well over 60% of dysentery cases in age group of 6 month to 5 years. Shigella flexneri is the commonest etiology encountered in developing nations. E. coli and campylobacter comprises the second important bacterial isolates in childhood dysentery. The objective of this study was to ascertain the clinical spectrum, etiological profile and local antibiotic sensitivity of the enteropathogens isolated.Methods: 147 serial dysentery cases admitted in GB Panth hospital Srinagar, which is an associated hospital of government medical college Srinagar from October 2014 to September 2015 were taken up for the study. A thorough and detailed history and examination was taken and recorded as per the proforma. Freshly collected stool sample was subjected to gross and microscopic examination; and after due bacteriological instructions was cultured on enrichment and selective media as per the need. Antibiotic sensitivity was done using disc diffusion method.Results: Maximum cases occurred in 1-5 years age group. Malnutrition grades II and III recorded the highest admissions. Most of cases had moderate dehydration. Although not frequent severe anemia, paralytic ileus and renal failure were the commoner complications. Shigella was grown in 12.24% of cases. Among them Shigella flexeneri serotype was encountered in 65% patients. Drug resistance was seen for many of the antibacterials like amoxycillin, ampicillin, norfloxacin, cotrimoxazole and nalidixic acid. However, they were susceptible to ceftriaxone and amikacin in well over 80% cases. E. coli isolates had similar antibiotic sensitivity profiles, with most susceptibility to amikacin and ceftriaxone.Conclusions: Drug sensitivity and resistance pattern is a variable phenomenon and changes from place to place and time to time. Hence there is a need to document the local pattern of an area so as to guide a judicious antibiotic administration.
Tracheoesophageal groove: a reliable landmark

Published: March 2019

Background: Galen first described the recurrent laryngeal nerve (RLN) as a nerve that descended from the brain to the heart, then reversed the course and ascended to the larynx and caused the vocal cords to move. Tracheoesophageal groove is useful for identifying the RLN. In the present study we studied the course of RLN in tracheoesophageal groove and its anatomical position, in patients undergoing thyroid surgery.

Methods: The study was conducted in the Department of ENT and Head and Neck Surgery, SMGS Hospital, for a period of two years, on the patients who underwent thyroid surgeries. Tracheoesophageal groove was considered first landmark to identify RLN position and only after meticulous dissection in the groove, the nerve could be identified. The nerve was carefully dissected and its position evaluated in relation with trachea and esophagus.  

Results: Trajectory of the nerves studied in the patients was mostly in the tracheoesophageal groove (TEG), seen in 113 (69.75%) nerves. 16.05% of the nerves were seen in the posterior half of the trachea while 4.94% of the nerves were seen to travel from TEG to anterior half of trachea and 1.85% from TEG to posterior half of trachea. 6.17% of nerves travelled from oesophagus to the TEG.

Conclusions: A uniform dissection procedure should be followed and the recurrent laryngeal nerve must be first looked for in the TEG, which serves as important landmark and later any deviation must be considered.

Published: March 2019

Background: Supracondylar fractures of the femur in adults account for only 7% of all femoral fractures. However, these fractures present with numerous complications. The purpose of this study was to assess the outcome of locking condylar plate in supracondylar fractures of femur in adults.

Methods: This study was based on 25 patients of supracondylar fracture of the femur treated with locking condylar plate at Srinivas Institute of Medical Sciences and Research Centre, Mukka, Suratkal, Mangalore. The patients were followed up for 1 year.

Results: In present study, 84% fractures were sustained due to road traffic accidents. In 23 (92%) patients, full weight bearing was achieved at 20 weeks while only 2 (8%) patients required more than 20 weeks. 80% of cases required less than 16 weeks for union while 20% required more than 16 weeks. Average injury to surgery time was 3.62 days in the present series. Superficial stitch infection occurred in two cases. Deep infection occurred in a grade 2 compound fracture in a male who was treated initially with debridement and antibiotics.

Conclusions: Good results are seen by distal femur locking condylar plate alone. It is the main implant of choice for distal femur fractures of all varieties. Best outcome is expected if fracture fixation is done following all the basic principles of fracture fixation. Advantage of the mechanical properties of a locking plate is definitely useful.

Published: March 2019

Background: Syphilis caused by spirochete Treponema pallidum is a bacterial sexually transmitted infection [STI] with protean manifestations. There is a rising trend of this disease due to changing sexual orientation and behavioural practices. The aim was to study the incidence, age, sex distribution, clinical presentation and serological findings of secondary syphilis in patients attending the Institute of Venereology in a tertiary care centre at Chennai.

Methods: Retrospective analysis of data of patients diagnosed as secondary syphilis who attended our institute over a period of 2 years from March 2015 and February 2017 was done. Complete epidemiological, clinical and investigational data were analysed.

Results: Among 57,316 patients who attended the STD clinic 459 patients were diagnosed to have syphilis. Among them 11.6% were found to have secondary syphilis with majority falling within the age group of 21 to 30 years. Among the 53 patients with secondary syphilis 94% were males, among which only 30% were married. Males having sex with males were affected more. Out of the various clinical presentations of secondary syphilis macular leisons was most commonly observed. Serological test done showed VDRL and TPHA positivity in 100% of patients with secondary syphilis.

Conclusions: There is increased prevalence of secondary syphilis among the males, especially among young unmarried males with homosexual orientation and promiscuity. Observations of this study emphasize the urgent need for implementation of programs to focus on sex education and counselling to the adolescents and young adults who tends to be the vulnerable population in the society.
