Paralelismo, ciclicidad y creatividad en el arte verbal maya yucateco
Authors: Vapnarsky Valentina
Published: May 2016

Este artículo contribuye a demostrar que el recurso discursivo del paralelismo en la tradición maya juega un papel esencial en diferentes niveles de organización discursiva, y no sólo en cuanto al verso y unidades contiguas como se ha señalado generalmente. Analizamos la variedad de niveles en los cuales se pueden desarrollar los paralelismos, así como la relación con otras figuras retóricas, en especial la ciclicidad, que se destaca como un recurso importante para el despliegue de paralelismos entre unidades distanciadas. El análisis se hace mediante el estudio detallado de un diálogo ritual de la peregrinación de San Juan Bautista entre los mayas macehuales (cruso’ob) de Quintana Roo (México). Confirma que los paralelismos discursivos se deben considerar no sólo como elementos estéticos o poéticos, con sus efectos emocionales y enfáticos, sino también como procesos de organización macrodiscursiva, con funciones temáticas, semánticas y pragmáticas.
Concepciones culturales, género y migración entre mayas yucatecos en Cancún, Quintana Roo
Authors: Rosales Mendoza Adriana Leona
Published: May 2016

Este artículo presenta algunos elementos que contribuyen a mantener la memoria cultural en mayas peninsulares inmigrantes en Cancún, Quintana Roo. Refiero algunas concepciones culturales (rituales, leyendas y concepciones) que permiten a inmigrantes de esta etnia continuar reproduciendo y perpetuando su sentido de pertenencia étnica de ese polo turístico. Los testimonios que se presentan corresponden a cinco entrevistas efectuadas con mujeres procedentes del oriente del estado de Yucatán (X-Can, Temax, Espita, Tunkás, Dzitás, Chemax y Valladolid) durante el proceso de investigación para la tesis de doctorado de la autora. Las reflexiones para la elaboración de este artículo surgieron en el proceso de dicha investigación y en observaciones de campo posteriores, en las cuales fue posible profundizar en relatos sobre los rituales de chaa chac y hetz-mek, la leyenda Xtabay, el sentido conferido al corazón, y la denominada "metáfora de los ojos de venado"
Los intérpretes generales de Yucatán: hombres entre dos mundos
Authors: Lentz Mark
Published: May 2016

Este artículo se centra en un tipo importante de intermediarios en el Yucatán colonial, los intérpretes generales del Juzgado Privado de Indios de Yucatán. Desde la época de Gaspar Antonio Chi en 1580 hasta la desaparición de esta corte en la década de 1820, estos hombres mediaron directamente en disputas de propiedades, quejas contra las autoridades, y tradujeron decretos inicialmente publicados en español para la mayoría maya hablante de la provincia. Sus actividades demuestran que Yucatán poseyó un alto número de individuos que dominaron tanto el maya como el español hasta finales del periodo colonial. Además, la cantidad de individuos calificados sirviendo extraoficialmente como intérpretes durante finales del siglo dieciocho, y el sorprendente número de no-mayas que necesitaron sus servicios, muestran también que el periodo colonial fue una época en la que el maya se extendió como lenguaje predominante en Yucatán, en lugar de una época de declive para ese idioma.
Los señores de la entidad política de 'Ik'
Authors: Velásquez García Erik
Published: May 2016

Este artículo constituye el primer intento de reconstrucción de la dinastía real de 'Ik' que s eha publicado. En 1973, el glifo emblema de la entidad política de 'Ik' fue asociado por Joyce Marcus con el sitio arqueológico de Motul de San José, asentado en las cercanías del lago Chaltunhá o Petén Itzá. Desde entonces, diversos datos arqueológicos y epigráficos han fortalecido la hipótesis de que la entidad política de 'Ik' tuvo su sede en esa zona del Petén, si bien su primera capital conocida residió posiblemente en Bejucal. Del mismo modo, se contempla la posibilidad de que más de un sólo dignatario haya portado simultáneamente el glifo emblema de 'Ik', pues fue un título regional usado por distintas ciudades del mismoe stado. En est etrabajos e identifican dos gobernantes de 'Ik' del Clásico temprano, siente u ocho del Clásico tardío, y uno o dos del Clásico terminal, aunque en las vasijas producidas en la región existen otros dignatarios cuyos nombres son difíciles de comprender o que carecen de fechas en Rueda de Calendario. Una aportación significativa del texto reside en identificar los sitios arqueológicos del Petén, Petexbatún y Usumacinta con los que el señorío de 'Ik' sostuvo relaciones de muy diversa índole.

Relaciones entre africanos e indígenas en Chiapas y Guatemala
Authors: Peña Vicenteño Juan Pablo
Published: May 2016

La presencia africana en la Audiencia de Guatemala en los siglos XVI y XVII ha sido poco estudiada. Por lo tanto, en este trabajo se analizarán los diferentes mecanismos que utilizó la corona española para el traslado de esclavos, como las licencias y el sistema de asientos. Asimismo, se estudiará la inserción de los africanos en la sociedad colonial y principalmente su interrelación con la población indígena nativa de la región.En los documentos coloniales referentes a matrimonios, podemos observar los procesos de "interculturalidad" en los cuales el esclavo africano intercambió elementos culturales que influyeron en la música. Tal fue el caso de la marimba, instrumento que dio identidad a la región de estudio. Por último, se pretende observar, a través del análisis de las narrativas indígenas originadas en la década de los 90´ del siglo XX, cómo en la cosmovisión indígena aún continúa la presencia de los "negros".

La lectura y comprensión de los antiguos textos jeroglíficos producidos por los mayas prehispánicos genera hoy una de las fuentes más valiosas que poseen los investigadores modernos para el estudio de esta cultura, pues encontramos en las inscripciones datos importantes sobre antiguos dignatarios, guerras entre ciudades, sucesiones dinásticas, ritos, etcétera.
Transformación en el tiempo: definiendo el sitio de Xuenkal, Yucatán, durante el periodo Clásico Terminal
Authors: Kam Manahan T. , Ardren Traci
Published: May 2016

El antiguo centro maya de Xuenkal, ubicado en la región Cupul, aproximadamente a 45 km hacia el noreste de Chichén Itzá fue uno de los sitios tierra adentro que contaban con una ocupación Sotuta sustancial. La investigación del Proyecto Arqueológico Xuenkal (PAX) se enfoca en el estudio de la cultura material Sotuta y su relación con la ocupación Cehpech del Clásico Tardío-Terminal con el propósito de entender la naturaleza de tal transición. Utilizando una metodología de excavación de pozos de sondeo en contextos domésticos sugerimos que la ocupación pre-Sotuta fue mucho más robusta de lo que originalmente pensábamos. Los resultados del estudio del patrón de asentamiento demuestran que existía un asentamiento Cehpech extensivo que se extendía hacia la periferia, y las excavaciones de las unidades domésticas revelan que durante el Clásico Tardío Xuenkal era un asentamiento mucho más próspero de lo que imaginábamos y que sus pobladores probablemente tenían un contacto estrecho y recíproco con sus vecinos de Ek’ Balam, Kulubá y Cobá. En contraste, el asentamiento Sotuta se limita a grupos residenciales localizados dentro del núcleo del sitio. Estos datos en conjunto sugieren que el control que ejerció Sotuta sobre Xuenkal está probablemente ligado al resultado de un conflicto político regional, más que una transformación autóctona.
Identification of Postclassic Maya Constellations from the Venus Pages of the Dresden Codex
Authors: Park Changbom , Chung Heajoo
Published: May 2016

La civilización maya, que floreció del 1200 a.C. a 1500 d.C., dejó numerosos textos jeroglíficos sobre el calendario y observaciones astronómicos. El Códice de Dresde, en particular, contiene el más detallado de dichos antiguos legados mayas. Las páginas 24 y 46 a 50 de dicho códice describen el calendario de Venus con los augurios correspondientes. Nosotros hemos notado que éste es un calendario Venus-Solar, y nuestro trabajo se enfoca sobre la posibilidad de que estuviera hecho para trabajar en conjunción con la aparición de determinadas constelaciones en el cielo. Es a través del análisis y descripción de las páginas de Venus que proponemos que las columnas en cada página describen el movimiento de Venus respecto de constelaciones mayores, en fechas que corresponden a eventos especiales, mientras que las fechas calendáricas se incrementan horizontalmente dentro del periodo sinódico de Venus. Aquí presentamos veinte constelaciones mayas identificadas desde las páginas de Venus asumiendo que la primera fecha, en la página 46, fue febrero 6 de 1228. También reportamos, como entendemos, las expresiones verbales sobre el movimiento de Venus y las constelaciones.
Apicultura y organizaciones de apicultores entre los mayas de Yucatán
Authors: Rosales González Margarita , Rubio Herrera Amada
Published: May 2016

En las comunidades mayas la apicultura continúa siendo una actividad relevante pero complementaria, cuya lógica y condiciones de producción se contraponen a las nuevas normas del mercado internacional. La integración de organizaciones apícolas se considera una estrategia para la “modernización” de la apicultura y la comercialización de la miel en mejores condiciones. Este trabajo se refiere al sentido que tanto la apicultura como estas organizaciones tienen para sus integrantes, a sus expectativas, intereses, aprendizajes y a la forma en que se relacionan con instituciones y agentes externos. El escrito se basa en entrevistas y observaciones realizadas en 12 organizaciones apícolas durante 2005 y 2006 en el marco del proyecto de investigación del centro INAH Yucatán “Organizaciones indígenas y procesos de desarrollo en comunidades mayas del sur de Yucatán”.

De la autonomía política y cultural de la provincia de Río Bec
Authors: Michelet Dominique , Taladoire Eric , Arnauld M. Charlotte , Lacadena Alfonso , Patrois Julie , Nondédéo Phillippe
Published: May 2016

Ubicada en el corazón de la península de Yucatán, a medio camino entre Dzibanché y Calakmul (las dos probables sedes de la dinastía Kaan durante el Clásico), la región Río Bec, tan atípica por su patrón de asentamiento, su arquitectura y su iconografía, plantea un problema en este nuevo contexto estratégico-político. Dada su posición central entre las dos sedes, dicha región podría haber formado parte del reino Kaan en un momento u otro de su historia. Para tratar de contestar esta interrogante, y considerando la casi total ausencia de inscripciones en la región, se hizo una revisión de los datos arqueológicos disponibles, confrontándolos en la medida de lo posible con datos históricos. Al analizar de manera diacrónica la cultura material de la región, todo parece indicar que Río Bec tuvo un desarrollo propio, linear y continuo, independiente de la gran urbe de Calakmul en tiempos de la dinastía mencionada.
La Corona: un acercamiento a las políticas del reino Kaan desde un centro secundario del noroeste del Petén
Authors: Canuto Marcello A. , Barrientos Q. Tomás
Published: May 2016

El Proyecto Regional Arqueológico La Corona estudia la región del noroeste de Petén, Guatemala, donde se localiza la antigua ciudad maya de La Corona, que recientemente fue identificada como el Sitio Q. La investigación ha incluido las excavaciones de arquitectura monumental, asentamientos, la elaboración de mapas, el uso de sensores remotos y la realización de estudios paleoclimatológicos y ecológicos. Desde el punto de vista de los modelos de la organización política, las investigaciones en La Corona presentan una oportunidad para estudiar la naturaleza y las relaciones políticas de los sitios secundarios. Los datos epigráficos relatan una afiliación directa entre La Corona y la dinastía gobernante en Calakmul, por lo que el primer centro seguramente fungió como punto clave para las estrategias de expansión de Calakmul por las Tierras Bajas Mayas durante los siglos VI y VII d.C. Aquí se presentan algunos resultados obtenidos en las investigaciones llevadas al cabo entre 2005 y 2009.
Análisis iconográfico preliminar de fragmentos de las vasijas estilo códice procedentes de Calakmul
Authors: García Barrios Ana
Published: May 2016

Las cerámicas estilo códice fueron elaboradas durante la segunda mitad del siglo VII y principios del VIII d.C. en un área de la Cuenca del Mirador que abarca ciudades como Nakbé, Tintal, Pacaya y otras como Calakmul. En este último lugar se han recuperado en los últimos años más de 700 fragmentos cerámicos que tienen un gran parecido estilístico con muchas de las temáticas de las vasijas que se encuentran en colecciones privadas y museos, todas ellas procedentes del saqueo masivo de la década de los setenta. Entre los temas reconocidos en los fragmentos de Calakmul se encuentran diferentes episodios del mito del Dios del Maíz, así como el lanzamiento del Bebé Jaguar y otros episodios donde participa el Dios Viejo, así como el título ampliamente empleado en estas cerámicas que designa a un grupo de poder conocido como chatan winik.
Las comisarías y subcomisarías del municipio de Mérida: entre la tradición y la modernidad
Authors: Lugo Pérez José A. , Tzuc Canché Lizbeth
Published: May 2016

Las comisarías meridanas son poblaciones rurales en las que sus habitantes, a pesar de estar vinculados al mercado de trabajo urbano del que obtienen la mayor parte de sus ingresos económicos, también conservan ciertos elementos de la economía campesina. Entre estas destaca la práctica de actividades agropecuarias que, en la mayor parte de los casos, son un complemento a las primeras y, en otros, fungen como las principales fuentes de trabajo y de ingresos. Desde esta perspectiva, dichas comisarías, como también otros pueblos de la zona henequenera de Yucatán, ostentan las características de lo que algunos autores han denominado ruralidad o nueva ruralidad. En este marco nos enfocaremos en la discusión de cómo las creencias y costumbres relacionadas con algunas de las principales prácticas culturales como las ceremonias agrícolas y las fiestas tradicionales, en particular las corridas de toros, han sido impactadas por factores sociales y económicos impuestos por el neoliberalismo económico iniciado en la década de los ochenta.
Politics in the Wester Maya Region (III): The Royal and the Non-Royal Elite
Authors: Bíró Péter
Published: May 2016

En una serie de artículos investigo el uso de varias palabras en las inscripciones mayas de la época Clásica de la Región Occidental que se conectan con la que nosotros llamamos política. Estas palabras expresan ideas y conceptualizaciones que ayudan a entender los matices de las relaciones entre las entidades políticas de las Tierras Bajas Mayas y su organización interna. En este artículo investigo la distribución de los títulos secundarios. Propongo que, en vez de indicar un crecimiento del poder de la élite secundaria, aquellos proporcionan evidencia de la existencia de diferentes géneros inscripcionales que tal vez reflejen procesos históricos diferentes dentro de cada región.
El jaguar transformado. Una hipótesis poliédrica a propósito de la danza El caballito blanco
Authors: Ramírez Torres Juan Luis
Published: May 2016

Desde las nociones de complejidad (Edgar Morin) y semiosfera (Iuri Lotman), y en el marco de la matriz cultural constituida por Mesoamérica, se analiza el sistema simbólico de la danza maya-chontal El Caballito Blanco, asociada sistémicamente al simbolismo del jaguar maya y mesoamericano. Para ello, se propone una estrategia metodológica consistente en la clasificación del conjunto simbólico —construido a lo largo de la historia por heterogéneos significantes y significados—, sustentada en la geometría del poliedro como una manera de pensar y ordenar analíticamente el continuum semiótico yokot’an, y sobre lo cual se propone una explicación respecto al proceso de transformaciones simbólicas ocurridas en el devenir cultural indígena desde el mítico felino hasta el ibérico equino, pero donde ambos quedan integrados en una misma estructura siempre de sentido Chontal-yokot’an, en lo particular y, de constantes mayas, en lo general.

The Problematic of Small-Scale Land Acquisition (Less than 5 Hectares) for Public Interest Development
Authors: Setiabudhi Donna Okhtalia
Published: May 2016

Land acquisition for public interest development is stipulated in Act No. 2 of 2012 concerning Land Acquisition for Development of Public Interest. One arrangement of land acquisition in legal substances that have been formed are small-scale land acquisition (less than 5 hectares), but it is still governed by very vague and thus susceptible to the multi-interpretation and raises doubts in its implementation. This paper discusses the problematic that arise due to unclear regulations concerning small-scale land acquisition and to provide solutions to these problems. Based on the discussion the authors concluded first, the problematic of small-scale land acquisition is the arrangement of land acquisition that is so vague that there is no clarity regarding the procedures for determining of location, the phase of land acquisition, which excludes public consultation, there is no regulation regarding preventive measures against the impact for the community around location of land acquisition. Second, the solution could be found to this problem is a regulation of small-scale land acquisition should ideally be regulated more comprehensively considering that small-scale land acquisition allows the emergence of adverse effects for the community around location of land acquisition so that the stages of planning and preparation that is set for the large-scale land acquisition is similarly applied for small-scale.

Solvent-Selection Criteria Based on Diffusion Rate and Mixing Quality for Steam/Solvent Applications in Heavy-Oil and Bitumen Recovery
Authors: Marciales A.. , Babadagli T..
Published: May 2016

Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of investments and operations. Attention has been given to solvent injection for this purpose, and it has been observed that high recoveries are achievable when it is combined with steam injection. Heavier (“liquid”) solvents (liquid at ambient conditions) are especially becoming more popular because of availability and transportation. High oil prices will allow the application of this kind of technique if a proper design is made to retrieve the injected solvent efficiently. “Liquid” solvents are advantageous because they yield a better-quality mixing (especially with very heavy oils and bitumen) but a lower diffusion rate than lighter solvents such as propane or butane. Despite this understanding, there still is not a clear screening criterion for solvent selection to mitigate both diffusion rate and the quality of the mixture.

In this study, two main solvent-selection-criteria parameters—diffusion rate and mixing quality—were considered to evaluate solvent-injection efficiency at different temperatures. An optical method under static conditions and image-processing techniques were proposed to determine 1D diffusivity of liquid solvent into a wide range of oil samples in a capillary tube. This sampling range varies from 40-cp oil to 250-cp oil, for which digital-image treatment was developed. X-ray computerized tomography (CT) was applied for heavier (and darker) oils (viscosity range of 20,000 cp to 400,000 cp). The diffusion coefficients were then computed through nonlinear curve fitting on the basis of an optimization algorithm to ensure that the obtained values were in agreement with available analytical solutions. Next, viscosity measurements and asphaltene precipitation for the same heavy-oil/solvent mixtures were performed to determine the mixing quality. The ideal solvent types for different oil types were determined by using the results from the diffusion-rate and mixing-quality experiments.

The experimental and semianalytical outcome of this research would be useful in the determination of the best solvent type for a given oil and in understanding the key factors that influence the quality of mixtures including viscosity reduction and probable asphaltene precipitation.
Community Structure of a Mental Health Internet Support Group: Modularity in User Thread Participation
Authors: Carron-Arthur Bradley , Reynolds Julia , Bennett Kylie , Bennett Anthony , Cunningham John Alastair , Griffiths Kathleen Margaret
Published: May 2016

Background

Little is known about the community structure of mental health Internet support groups, quantitatively. A greater understanding of the factors, which lead to user interaction, is needed to explain the design information of these services and future research concerning their utility.

Objective

A study was conducted to determine the characteristics of users associated with the subgroup community structure of an Internet support group for mental health issues.

Methods

A social network analysis of the Internet support group BlueBoard (blueboard.anu.edu.au) was performed to determine the modularity of the community using the Louvain method. Demographic characteristics age, gender, residential location, type of user (consumer, carer, or other), registration date, and posting frequency in subforums (depression, generalized anxiety, social anxiety, panic disorder, bipolar disorder, obsessive compulsive disorder, borderline personality disorder, eating disorders, carers, general (eg, “chit chat”), and suggestions box) of the BlueBoard users were assessed as potential predictors of the resulting subgroup structure.

Results

The analysis of modularity identified five main subgroups in the BlueBoard community. Registration date was found to be the largest contributor to the modularity outcome as observed by multinomial logistic regression. The addition of this variable to the final model containing all other factors improved its classification accuracy by 46.3%, that is, from 37.9% to 84.2%. Further investigation of this variable revealed that the most active and central users registered significantly earlier than the median registration time in each group.

Conclusions

The five subgroups resembled five generations of BlueBoard in distinct eras that transcended discussion about different mental health issues. This finding may be due to the activity of highly engaged and central users who communicate with many other users. Future research should seek to determine the generalizability of this finding and investigate the role that highly active and central users may play in the formation of this phenomenon.

This paper presents the results of tests carried out to determine how the dosage of bentonite added as binder, affects the properties of green pellets made of the limestone fines that originate from Lithothamnium limestone processing. Bentonite was added to limestone in different mass fractions (1, 2.5, 5 and 10%), whereas all the other parameters of the pelletizing process remained constant. The aim of pelletizing was to consolidate limestone fines and form mechanically stable pellets, provided that all the other properties of limestone remain unchanged. The pellets formed in this way were analysed applying DTA/TG analysis and FTIR and SEM analyses. The results showed uniform distribution of bentonite in the pellets, demonstrated that the pellets are compact and there is no formation of new compounds. The pellets were tested for resistance to impact, compressive strength and abrasion resistance. Also disintegration tests were performed to determine the time required for the pellet to disintegrate completely in water. These mechanical properties are essential for transport, handling, storage and general use of pellets. The values of most of the parameters established for pellets with 5% bentonite, meet the standards required for use in agriculture for liming acid soils, however their application is limited because their impact resistance is unsatisfactory and the time required for their complete disintegration in water is extremely short. It should be noted that further increase of bentonite content (over 10%) will not improve the quality of green pellets. In view of the results obtained, it is necessary to introduce drying into the pelletizing process in order to bring the green pellets into solid state.

Stigmatization and discrimination of patients with chronic hepatitis C
Authors: Kostic Marina , Kocic Biljana , Tiodorovic Branislav
Published: May 2016

Background/Aim. Chronic hepatitis C (CHC) is often associated with injectable drug users and human immunodeficiency virus coinfection for which there is stigmatization in society. The aim of this study was to identify the presence of stigma and discrimination of patients with CHC, as well as the influence of sociodemographic factors on the occurrence of stigmatization. Methods. A cross-sectional study was performed. Patients with CHC and conducted antiviral therapy completed an anonymous structured questionnaire consisting of sociodemographic questions and Hepatitis C stigma scale. Results. Out of 154 patients 61.7% were male and 72.1% from the city; 59.7% have completed secondary school; 61.7% were employed before the disease while 31.8% after the disease; 45.5% were unsatisfactory with financial situation; 54.5% were married; 37.7% lived with a spouse and children; 86.4% in their own house/apartment; 5.2% of the patients were abandoned by their partners, while 35.7% consumed drugs. A statistical significance of the stigma score was found in those who lived in the city (p = 0.018), unmarried (p = 0.005), abandoned by the partners after the diagnosis of CHC (p < 0.001), drug users (p = 0.002) and those living with parents (p = 0.034). Univariate regression analysis singled out as significant: residence (p = 0.018), living with their parents (p = 0.046), abandonment by a partner (p < 0.001) and drug use (p = 0.002). A multivariate regression model of independent variables singled out abandonment by partners (Beta = 5.158, p = 0.007). Men disagree significantly with the two elements inside stigma [not the same as the others (p = 0.035)] and hurt by the reaction of others (p = 0.047)). Conclusion. The presence of stigma in patients with CHC was proven. The results indicate the need to strengthen anti-stigma programs that will reduce their psychological and social problems and reduce stigmatization in society.
Apical root-end filling with tricalcium silicate-based cement in a patient with diabetes mellitus: A case report
Authors: Biocanin Vladimir , Milic Marija , Vucetic Milan , Bacevic Miljana , Vasovic Dina , Zivadinovic Milka , Cetkovic Dejan , Calasan Dejan , Brkovic Bozidar
Published: May 2016

Introduction. The material used for root-end filling has to be biocompatible with adjacent periapical tissue and to stimulate its regenerative processes. Tricalcium silicate cement (TSC), as a new dental material, shows good sealing properties with dentin, high compression strengths and better marginal adaptation than commonly used root-end filling materials. Although optimal postoperative healing of periapical tissues is mainly influenced by characteristics of end-root material used, it could sometimes be affected by the influence of systemic diseases, such as diabetes mellitus (DM). Case report. We presented apical healing of the upper central incisor, retrofilled with TSC, in a diabetic patient (type 2 DM) with peripheral neuropathy. Standard root-end resection of upper central incisor was accompanied by retropreparation using ultrasonic retrotips to the depth of 3 mm and retrofilling with TSC. Post-operatively, the surgical wound healed uneventfully. However, the patient reported undefined dull pain in the operated area that could possibly be attributed to undiagnosed intraoral diabetic peripheral neuropathy, what was evaluated clinically. Conclusion. Although TSC presents a suitable material for apical root-end filling in the treatment of chronic periradicular lesions a possible presence of systemic diseases, like type 2 DM, has to be considered in the treatment outcome estimation.

Introduction. Pseudomesotheliomatous lung carcinoma is a special, rare entity characterized by large pleural growth and minor invasion of lung tissue. Clinically, radiologically, macroscopically and even histologically this tumor can be misdiagnosed as malignant pleural carcinoma. Case report. We represent a 64-year-old male patient, former smoker. Due to difficulties in the form of dry cough, feeling of dis-comfort and pain in the right hemithorax, fatigue, heavy breathing, sweating, fever up to 39.6?C the patient was treated as with combined antibiotic therapy (macrolides, cephalosporins and penicillin), but without improving of his condition. Chest radiography showed a shadow of pleural effusion by the height of the front end of the third right rib. Chest MSCT showed the extremely thickened pleura apically and to the posterior along the upper right lobe in addition to existence of massive pleural effusion. Subpleural condensation of parenchyma ranging about 30 mm was described in the upper right lobe. Cytological analysis of the pleural effusion showed the presence of malignant cells impossible to differentiate whether they were metastasis of adenocarcinoma or malignant pleural mesothelioma. By histochemical and immunohistohemical analyses of a pleural sample, pseudomesotheliomataus lung adenocarcinoma was diagnosed. Conclusion. Pseudomesotheliomataus carcinoma of the lungs can be a diagnostic problem. Its diagnosis is based on recognition of histopathological characteristics which enable its discernment from the epithelial variant of malignant pleural mesothelioma.
A critical examination of the relationship between vaginal orgasm consistency and measures of psychological and sexual functioning and sexual concordance in women with sexual dysfunction
Authors: Therrien Stephanie , Brotto Lori A.
Published: May 2016

A substantial body of research supports the hypothesis that vaginal orgasm is associated with overall better health outcomes for women. The primary aim of this study was to examine correlates of orgasm consistency with intercourse (OCI) in a sample of women with sexual dysfunction to see whether these findings held in a clinical sample. Study 1 (n=255) focused on demographic and psychological correlates of OCI and Study 2 (n=81) focused on the association between sexual arousal concordance and OCI. A longer relationship length and higher orgasm scores predicted OCI whereas mood, sexual abuse history, and relationship satisfaction did not. In Study 2, sexual arousal concordance, as measured with vaginal photoplethysmography and a continuous self-report measure of sexual arousal, was not associated with OCI. These findings challenge the conclusions of Brody et al. that vaginal orgasm is a sign of psychological, sexual, and relational health.

Dacryocystorhinostomy (DCR) is a bypass surgery in which an anastomosis is made between the medial wall of the lacrimal sac & the lateral wall of the nasal mucosa by cutting the intervening bone at the level of middle meatus to restore the flow of tears when the obstruction is beyond the common canaliculus. The only successful treatment of chronic dacryocystitis is DCR. The aim of this study was to evaluate the surgical intervention of conventional external DCR without silicon tube intubation. This prospective study was conducted at General Hospital, Faridpur from July 2012 to June 2014. Eighty cases with chronic dacryocystitis were selected for the study. We excluded the patients with lacrimal fistula, failed DCR and gross nasal pathology like deviated nasal septum, grossly hypertrophied inferior turbinate, atrophic rhinitis, nasal tumour, and polyp from our study. The patients' mean age at the time of surgery was 41.9±8.1 years ranged from 30 to 60 years. The operation was done under local anaesthesia by applying same technique. Then the patients were followed up for 12 months. In this study, we observed recurrence in five patients (6.25%) and complications from DCR are infrequent and not sight threatening. There were seven patients with reactionary haemorrhage, one wound infection, three wound gap, two epicanthal fold, one granuloma formation and five failed DCR. The success rate is 93.75% who underwent external DCR for the management of epiphora due to nasolacrimal duct obstruction.Faridpur Med. Coll. J. Jan 2015;10(1): 20-22

Lymphangiomas are benign hamartomatous lymphatic tumours characterized by multiple communicating lymphatic channels and cystic spaces. Cystic lyphangiomas may be seen anywhere in the body but are common in neck, axilla, mediastinum and groin. Treatment options are surgical resection, radiation, sclerotherapy etc but have got high recurrence rate and complications. In the present study we hypothesized that complete surgical resection along with keeping a drain for 2-3 wks, may reduce recurrence rate. This prospective study was performed from July 2008 to June 2013. Total 21 children treated during this period by the technique of complete surgical excision with keeping drain tube in situ for 2 to 3 weeks. Ultrasound performed in all patients, CT scan and Duplex study performed in some patients, histopathology done in all patients. Patients with intra-abdominal lymphangioma not included in this study. Twenty one patients were operated during the study period and average duration of keeping drain tube was 18.57 days. Among the 21 cases 2 (9.52%) patients developed mild infection, 1 (4.76%) patient developed infection with pus formation and 1 (4.76%) patient developed recurrence. Our success in the treatment warrants further verification of potential benefits of keeping drain tube in situ for 2-3 weeks after surgical excision of lymphangiomas.Faridpur Med. Coll. J.

Computer Vision Syndrome
Authors: Arif Khan Mohammad , Alam Md Jahangir
Published: May 2016

Computer Vision Syndrome (CVS) is a condition in which a person experience one or more of eye symptoms and/or headache and back pain as a result of prolonged working on a computer. Bankers, account section workers, professional computer workers, excessive near work by mobile, laptop or tab users are commonly affected. Headache, eye strain, dryness, burning, grittiness, heaviness or watering, stiff shoulders, low back pain and general fatigue are main symptoms. The duration of computer work is directly related to eye symptoms; and longer duration tends to result in long-lasting complaints even after the work is finished. Professional workers should practice preventive measure. Correction of refractive errors, modification of work station, using antiglare screen filter and hourly eye exercise are the chief preventive strategy. Neglected person may have less/decreased working capacity and reduced productivity.Faridpur Med. Coll. J. Jan 2015;10(1): 33-35
Pancreatic Disorders and Diabetes Mellitus-A Review
Authors: Rahman Md Hafizur , Ali Md Yusuf
Published: May 2016

Diabetes mellitus is a common disease among patients with pancreatic cancer and chronic pancreatitis. Hyperinsulinemia and peripheral insulin resistance are the prevailing diabetic traits in pancreatic cancer, whereas reduced islet cell mass and impaired insulin secretion are typically observed in chronic pancreatitis. Whether or not a causal relationship exists between diabetes and pancreatic carcinoma is an intriguing but unanswered question. Diabetes often precedes pancreatic cancer and is thus regarded as a potential risk factor for malignancy. Conversely, pancreatic cancer may secrete diabetogenic factors. Given these findings, there is increasing interest in whether close monitoring of the glycaemic profile may aid early detection of pancreatic tumor lesions. Exocrine pancreatic insufficiency is frequently associated with diabetes, with high prevalence in both insulin-dependent and insulinindependent patients. The incidence of diabetes caused by exocrine pancreatic disease appears to be underestimated and may comprise 8% or more of the general diabetic patient population. Non-endocrine pancreatic disease can cause diabetes by multiple mechanisms. Genetic defects have been characterized, resulting in a syndrome of both exocrine and endocrine failure. Regulation of beta cell mass and physiological incretin secretion are directly dependent on normal exocrine function. Algorithms for diagnosis and therapy of diabetes should therefore address both endocrine and exocrine pancreatic function.Faridpur Med. Coll. J. Jan 2015;10(1): 36-39

Hydatid disease, caused by Echinococcus granulosus is still endemic in certain parts of world but not a common disease in our country. Hydatid cysts mainly involve the liver and lungs but any other organ can potentially be involved. Renal hydatid cyst is uncommon and represents 2-4% of hydatid cyst in human. We report a case of isolated hydatid cyst of right kidney in our surgical care. A 36 years old lady was admitted under our care with gradually increasing lump and mild pain in right lumbar region for 6 months. Ultrasonography revealed a diagnosis of hydatid cyst. IVU showed smooth filling defect in right kidney which displaced pelvicaliceal system. Serological tests were not done due to unavailability. The patient was operated on and endocystectomy, deroofing and marsupialization were done. Hydatid cyst was confirmed by histopathological examination. Albendazole was started 2 weeks before operation and continued postoperatively for 1 month. The patient was discharged on 8th postoperative day and was closely followed up for 3 years without any further development of hydatid cyst in any organ.Faridpur Med. Coll. J. Jan 2015;10(1): 40-43
Taboo Teens and Ancient Adults: Overpopulation Motifs in Fictional Literature for Children and Young People
Authors: Ford Jennifer
Published: May 2016

Literature for children and young people is uniquely positioned in terms of intended readership and literary genres such as the young adult dystopian novel to scrutinise intergenerational and human fertility issues associated with overpopulation. However, fictional texts that explore overpopulation have a narrative form that is unstable and unreliable due to prevailing conventions of subjectivity and optimism in children's and young adult literature. Derrida's last interview, Learning to Live, is pertinent to an understanding of motifs of overpopulation in literature for children and young people. Derrida's recognition of the ‘rights’ of future and present generations, and of the temporal intergenerational problems between parent as child, and child as parent, are explored in recent fictional texts for children and young people.
Is Overpopulation a Growth? The Pathology of Permanent Expansion
Authors: Vieira Patricia
Published: May 2016

Both economic and population growth are commonly understood as an indefinite, quantitative increase that is both necessary and desirable for human well-being. In contrast, proponents of a steady state economy and of the de-growth movement have advocated for an end to the dominant ideology of growth as a way to tackle environmental problems, but have eschewed a deeper questioning of the meaning of growing. In the final section of the article, I put forth an alternative, qualitative notion of human growth that embraces both our unfolding as a species and a conscious acceptance of our finitude and limits.
Escape Velocity: Hyperpopulation, Species Splits, and the Counter-Malthusian Trap (after ‘tipping points’ Pass)
Authors: Cohen Tom
Published: May 2016

The ban today on “population talk” (Diana Coole) by the liberal western traditions as unethical has the inverse effect in a post-‘tipping point’ world defined by future population culls of peripheries. It turns out that this ban not only advances the outcome the liberal tradition would most avoid but blinds it from seeing what is now underway before its eyes—a ‘species split’ engineered by the hyper-elite with one eye to the coming climate catastrophism. It turns out that the ban conceals that the western anthropos had from the first been defined as arche-eugenicist and extinctivist. This in turn illuminates the puzzling non-response of global leadership to the prospect of irreversible ecocide.
