Authors:   The Korea Society Of Educational Studies In Mathematics, Kim Hye Mi , Kim Yongseok , Han Sunyoung
Published: July 2018

This study used longitudinal data from the middle school year 2010 (1st grade in middle school) to 2015 (3rd grade in high school) in Seoul Education Longitudinal Study. Using the Potential Growth Mixed Modeling (LGMMs), it looked for patterns that similarly change in math achievement as the school grade goes up, and it divided into groups, and then the Simple Growth Models were compared for each group average. Beginning in the third year of junior high school, in case of the G1 (157 students, 5.83%) group that have low score in study vertical scaling and G2 group that have high score in study vertical scaling, the study vertical scaling scores are reversed after 2nd grade of high school, and in case of G3 group (2,308 students, 85.8%), there was no change in scores over the entire school year. And as a result of promoting Random Slopes to see the impact of the defined factors such as classroom attitude, satisfaction, and atmosphere on the average of study vertical scale scores, it shows that G1 group was not influenced by both classroom attitude, satisfaction and atmosphere and G2 group was influenced by class attitude and G3 group was influenced by class attitude and satisfaction. Based on the results of this study, it would like to explore implications and improvement method that can lead the school education reinforcing and shadow education reduction.

Fitts’ Law: On Calculating Throughput and Non-ISO Tasks
Authors: Roig-Maimó Maria Francesca , MacKenzie Ian Scott , Manresa-Yee Cristina , Varona Gómez Javier
Published: July 2018

We used a target-selection task to evaluate head-tracking as an input method for mobile devices. First, the method of calculating Fitts’ throughput is described by means of a raw data detailed example. Then, the method of calculating throughput is discussed for non-ISO tasks, since the procedure targets were randomly positioned from trial to trial. Due to a non-constant amplitude within each sequence of trials, throughput was calculated using two methods of data aggregation: the first one, by sequence of trials using the mean amplitude, and the second one, by common A-W conditions. For each data set, we used four methods for calculating throughput. The grand mean for throughput (calculated through the division of means and the adjustment for accuracy) was of 0.74 bps, which is 45 % lower than the value obtained using an ISO task. We recommend to calculate throughput using the division of means plus the adjustment for accuracy, and to avoid using the reciprocal slope of the regression model. We present various design recommendations for non-ISO tasks, such as: i) to keep amplitude and constant target within each sequence of trials, and ii) to use strategies to avoid or remove reaction time.
Keywords: Fitts’ law, throughput, ISO 9241-411, mobile HCI, head-tracking.

Published: July 2018

Tangible User Interfaces (TUIs) are those in which users interact with a digital system through the direct manipulation of physical objects (tokens). Tokens are directly linked to a certain data/functionality within the system, so manipulation of these objects affects the system behavior. This paper introduces TanQuery, a tangible system to support the process of learning Relational Algebra. TanQuery incorporates components to detect and track tokens, and to analyze and execute query trees. The system was tested by university students, and obtained results allowed to observe and analyze that students found this type of interface useful and pleasant.
Keywords: Tangible user interfaces; relational algebra.

Published: July 2018

Actualmente, los juegos pervasivos son uno de los tipos de experiencia de juego que causan el mayor impacto en los jugadores, pues rompen el entorno usual del juego en su dimensión espacial, temporal o social. Este documento tiene el objetivo de proponer, en esos juegos, una integración de la narrativa con la interactividad y la geolocalización. Esta integración requiere un modelo que represente y estructure la historia y su fusión con el resto de elementos del juego. Además, ese modelo debe permitir analizar la efectividad de la historia y cómo ésta ayuda a crear una buena experiencia de usuario. En este trabajo, proponemos una fuerte estructuración de la narrativa que incluye soporte a la geolocalización. A través de un ejemplo de diseño de una historia interactiva geolocalizada, se explican las diferentes características del modelo que hacen posible la creación de buena narrativa interactiva. Palabras clave: Narrativa; Juegos pervasivos; Narrativa geolocalizada; Experiencia de usuario; Videojuegos.

Published: July 2018

Son dönemin dikkat çeken yönetmenlerinden birisi olan Yorgos Lanthimos,
filmlerinde özgün konuları, alışılmışın dışında bir anlatı tarzıyla ele
almaktadır. Lanthimos, toplumsal düzene ve değerlere karşı olan eleştirilerini
filmlerindeki distopyan temsiller ile ortaya koymaktadır. Bu çalışma, toplumsal
düzene ilişkin olumsuz düşünceleri ve tasarımları ifade eden distopya
kavramının sinemaya yansımasını, Lanthimos’un sinematografik yaklaşımı
aracılığıyla değerlendirmeyi amaçlamaktadır. Çalışmada eleştirel bir güce sahip
sinema ile distopya arasındaki ilişkiye ve yönetmen Lanthimos’un filmlerindeki
distopyan unsurlara ilişkin tespitler yer almaktadır. Lanthimos’un distopyan
sinemasını değerlendirmek amacıyla son filmi olan The Lobster seçilmiştir. Yalnız yaşamanın yasaklandığı bir toplumu
anlatan ve çeşitli metaforik anlatılara sahip olan film, distopya kavramı
üzerine şekillendirilen nitel yöntem ile analiz edilmiştir. Elde edilen
bulgulara göre Lanthimos, özgürlüklerin kısıtlanması, insani değerlerin
yitirilmesi, yabancılaşma, umutsuzluk vb. gibi kavramları temsil eden distopyan
bir sinema anlayışını ortaya koymaktadır. Ancak Lanthimos, çoğu distopya gibi
aşırı bilimkurgu unsurları yerine kapalı topluma yönelik varsayımla hareket

Published: July 2018

Türkiye’de
siyasi seçimlerde uygulanan stratejilere bakıldığında, stratejilerin hayata
geçirilmesi için kullanılan mecralar farklı partilerde benzerlik
gösterebilmektedir. Ancak 21. yüzyılla beraber, yeni iletişim teknolojileri, dünyada
olduğu gibi Türkiye’de de sosyal hayatı doğrudan etkileyebilecek duruma gelmiş
ve siyasal iletişimde kullanılan ana mecralardan biri olmuştur. Özellikle
sosyal medya, kullanan kişi sayısı ve sahip olduğu özellikleri nedeni ile yeni
dönemin çok önemli bir siyasi taktiği haline gelmiştir. 2000’li yıllardan sonra
da Türkiye’deki partiler de bu önemli taktiği stratejilerinin en önemli
parçalarından biri olarak düşünmektedir. Son yıllarda bunun örneklerine sıklıkla
rastlanmaktadır.

Bu
çalışma Türkiye’de siyasal iletişim sürecinde sosyal ağlarda neler yapıldığı
temel düşüncesi ile ortaya çıkmıştır. Çalışmanın amacı; 2017 yılında Türkiye’de
yapılan başkanlık sistemine yönelik referandum sürecinde, sosyal ağlarda Recep
Tayyip Erdoğan’ın görsel imajının nasıl yansıtıldığını ortaya koymaktır. Çözülmeye
çalışılan temel sorunsal ise;  bir siyasi
liderin sosyal ağlardaki fotoğraflarında en çok nelerin öne çıkarıldığını belirlemektir.
Sorunsalın çözümlenmesi için, yapısal uygunluğu ve Türkiye’de kullanıcı sayısı
bakımından ilk sıralarda yer alan Facebook ve Instagram isimli sosyal ağlarda Recep
Tayyip Erdoğan’ın görsel kimliğinin nasıl yansıtıldığı, göstergebilimsel analiz
yöntemiyle irdelenmiştir. Recep Tayyip Erdoğan’ın sosyal ağlarındaki
fotoğraflarında; mavi, kırmızı ve beyaz renkler, pozitif imaj oluşturabilecek
beden dili, çoğunda takım elbiseli bireysel görüntüsü (çok azında seçmenle birlikte)
ve tebessümü öne çıkarılmıştır. Ayrıca fotoğraflarda Recep Tayyip Erdoğan ana
karakter olarak kullanılmış ve sadelik benimsenmiştir. Bu doğrultuda Recep

Conceptualizing change in marine governance: Learning from Transition Management
Authors: Kelly Christina , Ellis Geraint , Flannery Wesley
Published: July 2018

Coastal states are increasingly urged to transform their sectoral and fragmented marine governance regimes, and to implement integrated and holistic management approaches. However, to be successful, integrated governance mechanisms, such as marine spatial planning and ecosystem-based management, will involve transformative change of institutions, values and practices. Although ‘integration’ is commonly championed as an important normative attribute of marine management by academics, policymakers and environmental groups, it is often done so with little consideration of the complexity of institutional context in which a shift to new management approaches takes place. This paper reviews the most cited academic papers in the field of marine governance, showing that most overlook many of the key institutional challenges to integration, often derived from issues such as incumbency, path dependency, policy layering and other pragmatic strategies. While integrated management approaches have a normative capacity to fundamentally transform marine governance, the failure to understand the institutional dynamics that may impede effective implementation, leaves much of the research in this field naively impotent. There is a need, therefore, to develop a more realistic understanding of the context in which transformative change takes place. It is argued that Transition Management has the potential to both conceptualise and operationalise strategies to address these barriers based on a long term perspective using a participatory process of visioning and experimentation.

Authors: Cáceres Correa Silvia Alexandra , Hernández Navarro Elena , Leiva Suero Lizette Elena
Published: July 2018

La Fluorosis dental es una enfermedad grave que implica además un problema estético, caracterizada por una anomalía de las piezas dentales, que es el primer signo de que la persona ha estado expuesta a niveles elevados de flúor, en el Ecuador su prevalencia es mayor en la región andina. Objetivo: Realizar una revisión sistemática y crítica de la literatura sobre la Fluorosis dental. Material y Métodos: Se efectuó una revisión sistemática y crítica de la literatura, usando motores de búsqueda de artículos indexados en Scopus, Latindex, Scielo sobre el tema Fluorosis Dental. Resultados: La revisión sistemática de la Literatura  permitió analizar 20 artículos publicados en revistas indexadas sobre el tema Fluorosis Dental, evidenciándose que es una condición irreversible causada por la ingestión excesiva de fluoruros presentes en el medio ambiente, alimentos, pastas dentales, agua, enjuagues, que afecta no solo a la estética sino fundamentalmente a la formación y maduración normal de las estructuras del esmalte en dentición temporal y definitiva en grupos etarios comprendidos entre 1 - 18 años. Se analizó la documentación y se evidenció que entre los factores determinantes de la salud para esta patología tenían mayor relevancia los biológicos, sociales, medio ambientales y la asistencia sanitaria estableciendo que el patrón común de la patología era el suministro de agua y de ahí su posibilidad de prevención. Por ser el agua la fuente principal de fluoruros y su fluorización, hace varios años, se constituyó en estrategia, asumida por varios países como medio de prevención de caries, hoy por el contrario se prohíbe, al considerar que el consumo de alimentos y bebidas embotelladas, los efectos aditivos de los dentífricos y suplementos fluorados son suficientes y están dentro del límite establecido de aporte al organismo. Conclusiones: La Fluorosis dental puede ser evitable regulando la fluorización del agua de consumo en las comunidades andinas.

Published: July 2018

Background: Barrett’s esophagus a is metaplasia of normal squamous cells that line the lower part of the esophagus and carries a major risk for adenocarcinoma of esophagus. In Asian population, the prevalence of Barrett’s esophagus and adenocarcinoma are less common than in Western countries but has been increasing.Methods: This is a hospital based descriptive study comprising of 120 consecutive patients with symptoms of gastroesophagial reflux disease belonging to both sexes of any age group. The diagnosis of gastroesophagial reflux disease was based on the symptoms like heart burn and regurgitation. Upper gastrointestinal endoscopy was done in all the patients. Four quadrant biopsies were taken from the esophagogastric junction in suspected case of Barrett’s esophagus. The diagnosis of Barrett’s esophagus was confirmed histopathologically.Results: There were 44.2% males and 55.8% females, age ranging from 22 to 85 years mean being 44.33+13.37. Of them, gastroesophagial reflux disease was mild in 54.16%, moderate in 21.16% and severe in 16.66%. Upper Gastrointestinal endoscopy revealed non erosive gastroesophagial reflux disease in 50%, erosive in 45%, hiatal hernias in 5% and Barrett’s esophagus in 1.6%. Both patients with Barrett’s esophagus were elderly and had short segment (<3cm) involvement with no evidence of dysplasia or adenocarcinoma histopathologically.Conclusions: Endoscopic surveillance with detailed inspection and systematic biopsies is recommended for most patients with Barrett’s esophagus. Esophageal carcinoma if detected should be treated at the earliest.

Published: July 2018

Background: Early identification of severe acute pancreatitis is important for early stratification, goal directed fluid therapy, rationalizing level of care to improve outcome. Various clinical, laboratory and imaging scoring system has been used to identify severe acute pancreatitis with variable results. Recently a decision tree model was proposed using serum creatinine, serum lactate dehydrogenase and oxygenation index to predict severe acute pancreatitis. This system is easy and usable at our centre. Hence, we conducted the study to validate the decision tree model prospectively.Methods: Patients admitted with a diagnosis of acute pancreatitis were included in the study. Decision tree model was used to identify patients at high and low risk for severe acute pancreatitis. Sensitivity and specificity were calculated for prediction of the decision tree model.Results: Fifty-three patients were included in the study. Fourty-one (77.4 %) patients with mild acute pancreatitis, five (9.4 %) patients had moderately severe pancreatitis and seven (13.2 %) patients had severe acute pancreatitis. Sensitivity and specificity of decision tree model to predict severity of pancreatitis was 97.83% (95 % CI – 88.47% to 99.94%) and 71.43 % % (95 % CI – 29.04% to 96.33%) respectively with positive and negative predictable value of 95.74 % % (95 % CI – 87.45% to 98.64%) and 83.33 % % (95 % CI – 40.49% to 97.35%) respectively.Conclusions: Decision tree model with serum creatinine, lactate dehydrogenase, and oxygenation index is an easy and useful tool to predict patients at high risk of developing severe acute pancreatitis.

Acute transverse myelitis is a focal infl ammatory disorder of the spinal cord. One of the main etiologic factors include, multiple sclerosis, post-infectious and post-traumatic events although autoimmune phenomenon is the most common cause. Transverse Myelitis (TM) due to etiology other than Multiple Sclerosis has shown spinal cord involvement of two or more segments. Annually millions of active immunization with vaccines is carried out globally with few transverse myelitis caused because of the adverse reactions due to these vaccinations. In order to improve accuracy of reporting, research and diagnosis, the Transverse Myelitis Consortium Working Group (TMCWG) have produced criteria for the diagnosis of ATM. Here we report a case of TM in adult, diagnosed as TM consistent with the TMCWG criteria and probably this is the first ever been reported case from Nepal. Nepal Journal of Neuroscience.

Authors: Gautam Rupesh , Adhikari Deepak , Dhital Matrika , Thakur Sudip , Adhikari Bhawana
Published: July 2018

Introduction: The variation in the course of infraorbital canal and protrusion of the infraorbital nerve through it to the maxillary sinus may lead to its accidental injury during reconstructive or endoscopic sinus surgery. Preoperative identification of this variant will prevent unintended injuries. Methods: A retrospective study of 307 patients who underwent CT scan study of the paranasal sinuses at Chitwan Medical College, Nepal was conducted. The protrusion of infraorbital nerve to the maxillary sinus was identified and the length of the bony septum along with the infraorbital nerve was measured. It was further classified as Class I to III according to the length of the septum.Results: The prevalence of protrusion of inferior orbital nerve in our study was 11.40 % and bilateral protrusion was 5.8 %.  The median length of the protruding component along with the septum was 4.9 mm. Conclusion: Preoperative identification of the normal protrusion of infraorbital nerve to the maxillary sinus will prevent accidental injuries during sinus surgery. CT scan of the paranasal sinus would be the modality of choice for identification of this variant.

Multiple Relationships
Authors: Brownlee Keith , Halverson Glen , Chassie Ahlea
Published: July 2018

Working in a rural community locates the professional in a wider social network as community members often expect more from their professionals; not only as service providers, but also as engaged members of the community. This can result in the rural social worker being highly visible both personally and professionally and it can also lead to overlapping relationships. These higher expectations can place stress on the worker in terms of maintaining accepted professional roles and a sense of professional identity. This qualitative study explores the first-hand experiences of a cross-section of service providers in more than a dozen communities within northwestern Ontario and northern Manitoba, Canada. The responses of the participants provide some insight into how rural practitioners maintain their professional identity when working within the unique demands of the rural and remote context. Recurring themes from the interviews suggest that these professionals craft their own informal decision-making processes to address intersecting roles, community gossip, and personal isolation, even while, in some cases, practicing in their home community. The findings provide greater understanding of the pressures and realities of working in small remote towns and the challenges of responding to the expectations and realities of relationships including the expectation of working with friends and family members of friends or colleagues: issues that have not been adequately studied in the literature to date.

Published: July 2018

Several studies have indicated a worldwide trend for higher gall-forming insect richness on sclerom orphic vegetation growing in infertile soils. The goal of this study was to survey the gall-forming insect fauna in the varzea, a seasonally flooded forest in the Amazonian region. Samples were taken at Mamirauá Sustainable Development Reserve, AM , Brazil. 21,098 insect galls belonging to 236 morphotypes were found on 242 tree crowns. The number of gall morphotypes was correlated with the number of plants sampled and gall abundance. Contrary to the predictions, we found a high richness and abundance of galling insects in the

varzea, a non-scleromorphic vegetation that grow in fertile soils. The explanation to the trends found may lie on plant physiological

adaptations to flooding and occurrence of different plant communities due to different flood levels and flooding time extents, or even due to the harsh conditions found in the upper canopy.
IDENTIFICAÇÃO DAS ESPÉCIES DE APISTOGRAMMA REGAN (CICHLIDAE: PERCIFORMES) DA DRENAGEM DOS LAGOS AMANÃ E URINI (AM, BRASIL) E CHAVE PARA AS ESPÉCIES DE OCORRÊNCIA LOCAL

Published: July 2018

The identification of species of Apistogramma Regan, one of the most diversified cichlid genus, found in lakes Amanã and Urini, and tributaries (Amanã Sustainable Development Reserve), Japurá-Solimões drainage, Brazilian Amazon, is herein presented. Individuals of the genus collected in the area were previously classified in eight morphotypes separated in A. agassizii, A. cacatuoides and six unidentified types. After detailed analyses, it was concluded that these eight morphotypes belonged, in fact, to five species. The diagnosis for each species is presented, as well as an identification key for the area. Briefly, individuals formerly identified as Apistogramma sp.2 belong to a species, possibly yet undescribed, of Pertensis group, thus classified as Apistogramma gr. pertensis. Apistogramma sp.3 was identified as A. hippolytae and Apistogramma sp.4 as Apistogramma cf. eunotus. Individuals formerly classified as A. cacatuoides are, in fact, A. bitaeniata. Individuals formerly classified as Apistogramma sp.1 are, in their majority, young specimens of A. agassizii, and few A. bitaeniata. Individuals at first classified as A. agassizii really correspond to the referred species. The results made possible the prompt identification of occurring species, aiding additional scientific studies and the further use of these species in the ornamental fishes management by Amanã Reserve riverine communities.
CONSERVAÇÃO AMBIENTAL E DIREITOS MULTICULTURAIS: APONTAMENTOS SOBRE DIREITO E CIÊNCIAS

Published: July 2018

From an interdisciplinary approach, focused on human sciences, this work is concerned with action situations that have occurred in protected environmental areas. these action situations do not involve only questions regarding socio- environmental rights and obligations seen from a state juridical point of view – here we are dealing with the superposition of two constitutionally protected domains: environment and cultural diversity. these actions also lead us to reflect on the importance and limits of scientific knowledge, on the positivated rights, and on the state itself as legitimate delineators, capable of defining and managing brazilian public policies, in particular those destined to the protection of the environmental and cultural.
ASPECTOS BIOLÓGICOS DE PYRRHULINA SEMIFASCIATA STEINDACHNER, 1876 (CHARACIFORMES: LEBIASINIDAE) NA RESERVA DE DESENVOLVIMENTO SUSTENTÁVEL AMANÃ, AM.

Published: July 2018

The present work aimed characterizing some biological aspects of Pyrrhulina semifasciata in the Reserve of Sustainable Development Amanã, Amazonas.  Of the 472 sampled individuals, 126 were females and 42 were males. Sex identification of 304 individuals was not possible due to the small size of their gonads. The growth was considered isometric, with individuals’ length ranging from 10 to 57 mm. Fish immature and in maturation process were found during all the sampled period (April 2006 to February 2007), indicating that reproductive activity occurs throughout the year, but it is more intense from December to February. Average fecundity was estimated at 939 oocytes. This study supplies basic information about P. semifasciata, a species too little studied with a great ornamental potential.
The Rise and Decline of the Bank of Italy's Autonomy between 1893 and 1936. A historical interpretion
Authors: Lardo Alessandro , Lombardi Rosa , Trequattrini Raffaele , Cuozzo Benedetta
Published: July 2018

The aim of this paper is to analyse the autonomy of central banks from a historical perspective, with reference to the founding and development of the Bank of Italy in the period between its inception (1893) and the passing of the Italian Banking Law of 1936. The issue of the autonomy of central banks from governments and budgetary policies has been investigated by several scholars, for whom the degree of autonomy is linked exclusively to factors connected with those wielding power or influence at the time, and factors related to the contingent historical and economic situation. Few studies so far have investigated the causes of the evolution of the degree of autonomy of the central banks, considering this evolution as strictly linked with the process of central state autonomy. The authors aim to investigate the evolution of the Bank of Italy's level of autonomy in light of Michael Mann's thinking.

Background: Anti-mullerian hormone (AMH) in largely expressed throughout folliculogenisis (by granulosa cells in ovarian follicles) but highest in pre-antral and small antral steges (<4mm) drameter of development.Objective: To analyse the usefulness of plasma anti-mullerian hormone (AMH) measurement as a test for assessing ovarian reserve in Polycystic ovary syndrome with sub fertility,Methodology: Women with PCOS and sub fertility, were included in this study with age group 18-35yrs. This Prospetive cohort study done in 30 cases in ShSMC with purposive randomized sampling, from January 2015 to December 2015. Serum, plasma & for evaluation of PCOS, preferably TV-USG was done.Result: In this study we analyze 30 serum samples from patient aged between 18-35 years and transvaginal ultrasonography was done simultaneously. Mean age group of my patient was 25.2±4.7 years which correlates with AMH level in PCOS which is statistically significant (p<0.001). Mean level of AMH is 5.7±4.9 mg/ml which is also correlate with transvaginal USG scan with the feature of PCOS (p<.0.001). More than 50% woman presents with features of subfertility with PCOS and 46.7% are normal ovaries. Mean menstrual day 7.6 (4-12 days) which have a good linear correlation with irregularities of menstrual cycle and PCOS (p<0.05).Conclusion: To conclude AMH appears to have a major inhibiting role during folliculogenesis, which may contribute to anovulation in PCOS. The reason for the raised AMH in PCOS may give clues as to the mechanism os anovulation.J Shaheed Suhrawardy Med Coll, June 2017, Vol.9(1); 3-5

Background : Complications of pregnancy and childbirth have always been one of the leading causes of death and disability among women of reproductive age in developing countries .Globally, postpartum haemorrhage is the single most important cause of maternal death, accounting for about 25% of the total and claiming an estimated 1,50,000 lives annually. Among the postpartum hemorrhage, the primary postpartum hemorrhage is more prevalent, but sufferings from secondary postpartum hemorrhage have been emerging. With the rising trend of cesarean section rate, the incidence of secondary postpartum hemorrhage is also rising.Objective: The objectives of this study is to evaluate secondary postpartum hemorrhage cases following cesarean section and vaginal delivery with the aim of reducing the maternal mortality at child bearing age.Methods: This is a cross sectional observational study in the department of Obstetrics and Gynaecology, DMCH , by purposive sampling method. Total 100 cases of secondary PPH were observed during 1st January 2013 to 31 December 2013.Result: In this study, among the cases 67% were following cesarean section and 33% were following vaginal delivery, mean age of the patients were 29 year, parity ranges from 1 to 5. Regarding the outcome of secondary PPH, severe anaemia, anaemic heartfailure, renal failure and DIC were common in cesarean sections along with hazards of massive blood transfusion and jaundice. 7 patients were died in post cesarean cases and 2 died in post vaginal delivery cases. Causes of death were due to hemorrhagic shock & septicemia.Conclusion: In this is study, the rate of secondary PPH is 67% following cesarean section which is very much alarming . The outcome of secondary PPH following cesarean section is worse than vaginal delivery.J Shaheed Suhrawardy Med Coll, June 2017, Vol.9(1); 23-25

Solid pseudopapillary neoplasm of pancreas (SPN) is a rare entity; therefore proper diagnosis, evaluation and formulation of treatment protocols is difficult. The commonest presenting symptom is abdominal pain. This article presents a case of solid pseudopapillary neoplasm of pancreas in a 35 years old lady. A high index of clinical suspicion is necessary to suspect and diagnose SPN. This diagnosis should be borne in mind when young female patients present with a pancreatic mass.J Shaheed Suhrawardy Med Coll, June 2017, Vol.9(1); 31-34

Though anorectal foreign body cases are rare, they have become increasingly frequent in recent years. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault. The diagnosis may be made by rectal examination and metallic objects can be confirmed by plain abdominal radiographs. Transanal removal is only possible for very low-lying objects, while patients with high-lying foreign bodies usually require an operative intervention. An early decision of laparotomy should only be made after subjecting the patient to suitable investigations to determine exact location of the object, in order to avoid any inadvertent damage to the adjoining vasculature as well as anal incontinence. . We report the case of a young male who presented at surgery department of Shaheed Suhrawardy medical college hospital with severe rectal pain due to insertion of an apple into rectum by some eunuchs. It was successfully removed transanally under spinal anesthesia. Post operative period was uneventful and referred for psychiatric consultation.J Shaheed Suhrawardy Med Coll, June 2017, Vol.9(1); 35-37
